Further, the technical solution of the embodiments of the present disclosure may be applied to Multi-carrier transmission system which adopts non-orthogonal multiple access technology, for example, adopting Orthogonal Frequency Division Multiplexing ("OFDM"), Filter Bank Multi-Carrier ("FBMC"), Generalized Frequency Division Multiplexing ("GFDM"), and Filtered-OFDM ("F-OFDM") system or the like.

    [0040] The terminal device in the embodiment of the present disclosure may refer to User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, and a wireless communication device, a user agent or a user device. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device or a computing device with wireless communication functions or other processing devices connected to wireless modems, an in-vehicle device, a wearable device, a terminal device in the future 5G network or a terminal device in the future evolved Public Land Mobile Network (PLMN) and the like, which are not limited in the embodiment of the present disclosure.

    [0041] The network device in the embodiment of the present disclosure may be a device for communicating with a terminal device, where the network device may be a base station (Base Transceiver Station, BTS) in GSM or CDMA, or a base station (NodeB, NB) in a WCDMA system, or an evolved base station (Evolutional NodeB, eNB or eNodeB) in the LTE system, or a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, and a network device in a future 5G network or a network device in a future evolved PLMN network, which is not limited by the embodiment of the present disclosure.

    [0042] Fig. 1 is a schematic diagram of an application scenario of an embodiment of the present disclosure. The communication system in Fig. 1 may include a terminal device 10 and a network device 20. The network device 20 is configured to provide communication services for the terminal device 10 and access a core network. The terminal device 10 accesses the network by searching for synchronization signals, broadcast signals, and the like transmitted by the network device 20, thereby performing communication with the network. The arrows shown in Fig. 1 may represent uplink/downlink transmissions through a cellular link between the terminal device 10 and the network device 20. In the embodiment, the network device 20 supports Slice 1, Slice 2, and Slice 3, and the terminal device 10 supports Slice 1, Slice 2, and Slice 4.

    [0043] A slice herein refers to a set of network functions (including core network functions and/or access network functions), and any other description having the same function has an equivalent effect.

    [0044] In the future, logically, each network slice represents a type of service requirement of a certain type of terminal device. The network device selects a corresponding network function to match a service according to service requirements of the terminal device, and forms a corresponding slice.

    [0045] The most ideal way is to dynamically combine the functions of the core network device and/or the access network device according to the service requirements of the terminal device, and then make configuration for the terminal device. For example, if a physical network terminal device needs to be sent by a small packet, it needs to configure or activate a random access function and a recovery function for the network; as for a terminal device that supports a licensed-assisted access (LAA), LAA functions may be configured or activated for the network if necessary. However, complexity of the network configuration in this manner is high, and the implementation is quite cumbersome. The simplified solution is that the network device forms multiple matching slices in advance according to the type of the terminal and the type of the service, and when the terminal device needs to use the corresponding slice, the requirement is sent to the network device, and then the network device configures the resources to the terminal device according to the corresponding slice requirement.

    [0046] In a network configuration process, although multiple network slices can be supported at the same time, it need to solve the problem that how to handle the residing and access of different slice terminals supporting different slice under the limited resource. At the same time, the terminal device may simultaneously support multiple network slices, the terminal also needs to choose to use which network slice for residing and access, and let the network device learn about its own idea with respect to different network slices, so that the network device can select corresponding resources for itself better.

    [0047] For convenience of description, the flow of the wireless communication method 100 according to an embodiment of the present disclosure will be briefly described firstly with reference to Fig. 2. As shown in Fig. 2, the method 100 includes following steps.

    [0048] In step S101, a device 1 determines network slice information, wherein the network slice information is configured to indicate multiple network slices.

    [0049] S102, the device 1 sends the network slice information to a device 2.

    [0050] S103, the device 2 receives the network slice information sent by the device 1.

    [0051] S104, the device 1 determines, according to the network slice information, at least one network slice supported by the device 2 from the multiple network slices.

    [0052] S105, the device 1 determines a target network slice from the at least one network slice determined in S103.

    [0053] S106, the device 1 performs configuration or operation according to the target network slice.

    [0054] It should be noted that the device 1 herein may be a terminal device or a network device; the device 2 may be a terminal device or a network device. For convenience of description, the following describes the interaction between the terminal device and the network device as an example.

    [0055] The network slice information herein may include slice information of multiple network slices, for example, functions supported by each network slice, a cell to which each network slice belongs, a probability that the terminal device accesses each network slice, an identifier of each network slice, and priority of multiple network slices, and other information. The network slice information herein may be configured to indicate multiple network slices supported by the device 1, and may also include network slices supported by other devices. For example, the network device 1 sends multiple network slices supported by the network device 1 to the terminal device, and may also send network slices supported by neighboring network devices to assist the terminal device to perform reselection.

    [0056] The configuration or operation herein may be the behavior of the terminal device or the network device, such as the terminal device residing in a cell, the terminal device accessing the network device, or terminal device handing-over a cell.

    [0057] The target network slice herein can be one or more network slices.

    [0058] Therefore, through the wireless communication method in the embodiments of the present disclosure, by learning about network slice information of a peer end, the condition of multiple network slices sent by the peer end can be learnt about; and accordingly, a target network slice can be better selected to perform wireless communication, so as to improve the quality of the wireless communication.

    [0059] A wireless communication method according to an embodiment of the present disclosure will be separately described from the perspective of both ends of the communication device, respectively, in conjunction with Figs. 3 and 4.

    [0060] Fig. 3 shows a schematic block diagram of a wireless communication method 200 in accordance with an embodiment of the present disclosure. As shown in Fig. 3, the method 200 includes:

    S210, a first device receiving network slice information sent by a second device, the network slice information being configured to indicate multiple network slices;

    S220, the first device determining a target network slice from the multiple network slices according to the network slice information, the target network slice including at least one network slice supported by the first device; and

    S230, the first device performing wireless communication according to the target network slice.



    [0061] It should be understood that the first device performing wireless communication may be communicating with the second device, or may be communicating with other devices except the second device. For example, the network slice information includes information of network slices supported by other devices. The first device selects the target network slice to perform wireless communication with other devices.

    [0062] In an embodiment, the first device is a terminal device, and the second device is a network device. The network device may broadcast the slice information of multiple network slices to multiple terminal devices. After the terminal device receives the slice information of multiple network slices sent by the network device, the terminal device selects at least one network slice supported by itself from the multiple network slices, and then the terminal device determines a target network slice from the selected at least one network slice, thereby accessing the network device according to the target network slice or residing in a cell of the target network slice. For example, if the network slice information received by the terminal device includes slice information of Slice1, Slice2, Slice3, Slice4, and Slice5 while the terminal device supports Slice1, Slice2, and Slice6, at least one network slice selected by the terminal device may be Slice1 and Slice2. If the terminal device processes Slice1 with a priority higher than Slice2, the terminal device selects Slice1 from Slice1 and Slice2 as the target network slice.

    [0063] In another embodiment, the first device is a network device, and the second device is a terminal device. The terminal device may send, to the network device, slice information of multiple network slices. After the network device receives the slice information of the multiple network slices sent by the terminal device, the network device selects at least one network slice supported by itself from the multiple network slices, and then the network device determines a target network slice from the selected at least one network slice, thereby configuring or selecting a cell to handover or reside for the terminal device according to the target network slice. For example, if the network slice information received by the network device includes slice information of Slice1, Slice2, Slice3, Slice4, and Slice5 while the network device supports Slice1, Slice2, and Slice6, at least one network slice selected by the network device may be Slice1 and Slice2. If the network device processes Slice1 with a priority higher than Slice2, the network device selects Slice1 from Slice1 and Slice2 as the target network slice.

    [0064] Optionally, in the embodiment of the present disclosure, the method further includes: the first device acquiring first priority information and/or second priority information, wherein the first priority information is configured to indicate a sequence of processing network slices supported by the second device from the multiple network slices by the second device, the second priority information is configured to indicate a sequence of processing network slices supported by the first device; wherein the first device determining a target network slice from the multiple network slices according to the network slice information includes: the first device determining the target network slice from the multiple network slices according to the first priority information and/or the second priority information.

    [0065] For example, the network device sends priority information of the network slice supported by five network devices Slice1, Slice2, Slice3, Slice4, and Slice5 to the terminal device, such as Slice1>Slice2>Slice3>Slice4>Slice5. The terminal device supports three network slices Slice1, Slice2, Slice3 and Slice6, and Slice1<Slice6<Slice3<Slice2. The terminal device can select the network slice Slice1 that is most preferentially processed by the network device from Slice1, Slice2, and Slice3. The terminal device can also select the network slice Slice2 that is most preferentially processed by the terminal device from Slice1, Slice2, and Slice3. The terminal device may also select the first two network slices Slice1 and Slice2 that are preferentially processed by the network device from Slice1, Slice2, and Slice3. The terminal device may also select the first two network slices Slice2 and Slice3 that are preferentially processed by the terminal device from Slice1, Slice2, and Slice3. The terminal device may also select Slice2 that is preferentially processed by both the network device and the terminal device. The terminal device may process the priority of the multiple network slices according to the network device, and/or the terminal device handles the priority of multiple network devices to determine the target network slice. The target network slice can be either one or more. The present disclosure is not limited thereto.

    [0066] It should be understood that the first priority information and the second priority information of the embodiment of the present disclosure may be pre-configured by the network device and/or the terminal device, or may also be determined by the network device and/or the terminal device according to a service state in a period of time. The manner of determining the priority information is not limited in the embodiment of the present disclosure.

    [0067] In addition, the first priority information and/or the second priority information herein may be associated with the network slice feature. For example, the priority of the corresponding network slice may be determined according to the identifier and priority information of the network slice. For example, the network slice supporting the function 1, function 2, and function 3 is identified as Slice1, and the network slice supporting the function 2, function 3, and function 4 is identified as Slice2. If the priority of the function 1 is greater than that of function 2, much greater than that of function 3, and further much greater than that of function 4, it can be determined that the priority of Slice1 is higher than that of Slice2.

    [0068] It should also be understood that the network slice supported by the first device herein may refer to a part of network slices including the target network slice, or may refer to all network slices supported by the first device; and the network slice supported by the second device herein may refer to a part of network slices including the target network slice, or may also refer to all network slices supported by the second device.

    [0069] Optionally, in the embodiment of the present disclosure, the network slice information includes the first priority information, and the first device acquiring the first priority information includes: the first device acquiring the first priority information from the network slice information.

    [0070] Optionally, in the embodiment of the present disclosure, the terminal device residing in a cell to which the target network slice belongs according to the target network slice includes: the terminal device residing in a cell to which the target network slice belongs according to the target network slice, when determining that a network slice with highest priority from network slices supported by the network device and processed by the network device and a network slice with highest priority from network slices supported by the terminal device and processed by the terminal device are identical.

    [0072] Optional, the access network device receiving the first priority information authenticated by a core network device and sent by the terminal device, and/or the method 200 further includes: the access network device sending the first priority information to a core network device when determining that the first priority information needs to be authenticated; the access network device receiving an acknowledgement message of the priority information sent by the core network device.

    [0073] Optionally, the terminal device may send the priority information to the core network device by using the signaling of an access layer or a non-access stratum, and the core network device feeds back to the access network device after completing the verification and confirmation. The terminal device may also send the priority information to the access network device directly through the access layer, and if necessary, the access network device forwards the information to the core network device for verification and confirmation.

    [0077] For example, the terminal device supports Slice1, Slice2, and Slice3. If a current service of the terminal device is function 1 and only Slice1 supports the function 1, the terminal device may preferentially select Slice1 to access the network device. If the current service of the terminal device is updated to a function 2 and only Slice 2 supports the function 2, the terminal device can preferentially select Slice 2 to access the network device.

    [0081] In order to solve the access problem of terminals with different network slicing capabilities in the cell, the network device broadcasts the slice priority to the terminal, to indicate the slice capability of preferentially accessing and processing in the cell, which includes the terminal residing priority, such as the terminal with the slice capability 1 preferentially residing in the cell 1; may also include the terminal slice access probability, that is, the terminal initiating the access according to a certain probability when accessing the terminal. When the terminal uses different slice capabilities to access, the terminal may preferentially select corresponding network slice resources for access according to its own slice capability.

    [0082] An idle state operation: when the terminal initially resides, the terminal selects a first cell that can be accessed to reside, and meanwhile receives information such as slice information (slice identifier, slice priority) sent by the cell. When the slice priority sent by the cell does not match the slice function of the terminal (for example, the cell slice priority is to preferentially process enhanced mobile broadband services, and the terminal slice priority is to preferentially process massive low-power connection services), other cells are selected to reside through reselection. The cell accessed at this time can send slice information of neighboring cells, to assist the terminal to perform reselection.

    [0083] A connection state operation: when the terminal initiates initial access of a certain slice, the terminal may access according to information such as an access probability of a corresponding slice included in the slice information. When the function that the terminal wants to start can be completed by multiple slices (for example, the packet transmission can be completed through enhanced mobile broadband or through massive low-power connection), a corresponding slice with the highest priority is selected to complete the access.

    Embodiment 2: Terminal slice priority and use of the terminal



    [0084] The terminal initiates the corresponding slice priority according to its own capabilities and/or service requirements, and performs idle state network residing according to the priority. Under a connected state, by notifying the network of the network priority information, it may assist the network to perform handing-over towards the terminal.

    [0085] An idle state operation: when the terminal resides in the idle state, considering the network slicing function possessed by multiple cells and its own terminal slicing function priority, it is preferably to select a cell to which the slicing function with high priority belongs to reside. For example, a network cell A supports slices 1, 2, a network cell B supports slices 2, 3, the terminal supports slices 1, 2, and the slice 1 has higher priority, then the terminal preferentially resides in the network cell A. If the terminal only supports slice 2, it is feasible to reside in either cell A or cell B.

    [0086] A connection state operation: when the terminal performs handing-over in the connected state, the network preferably selects the cell to which the slice function with high priority belongs for handing-over, according to the slice function priority reported by the terminal. For example, network cells A and B are both target cells for handing-over, wherein the network cell A supports slices 1, 2, the network cell B supports slices 2, 3, the terminal supports slices 1, 3, and the slice 1 has higher priority, then the network may preferentially handover the terminal to the network cell A. If the terminal only supports the slice 2, it is feasible to handover to either cell A or cell B.

    [0087] Therefore, in the wireless communication method in the embodiment of the present disclosure, it enables the terminal to select the most suitable access point for access by notifying information of different network slices of the peer end and the processing priority for different network slices. In addition, it enables the network to learn about the slice priority of the terminal when supporting multiple slice functions, so as to better match the terminal residing, access and handing-over behavior, and improve experience of end users.

    [0088] In addition, in the foregoing method embodiments, steps on the terminal device side may be separately implemented as the wireless communication method on the terminal device side, and steps on the network device side may be separately implemented as the wireless communication method on the network device side. In each of the foregoing method embodiments, the network device is usually a base station, and the terminal device is usually user equipment.

    [0090] It should also be understood that, in various embodiments of the present disclosure, the sequence numbers of the above processes do not imply a sequence of executions, and an execution order of the processes should be determined by its function and internal logic, but should not be make any limitation on implementation of embodiments of the present disclosure.
