    Description

    TECHNICAL FIELD



    [0001] The present invention relates to the field of mobile communications technologies, and in particular, to a resource allocation method and device for direct communication between user devices.

    BACKGROUND



    [0002] A device to device proximity service (Device to Device Proximity Service, D2D ProSe) has become a research subject of the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) in a Long Term Evolution (Long Term Evolution, LTE) Rel.12 system, and begins to be supported from the Rel.12 system. Direct communication between user devices includes a signal discovery process and a direct communication process. The signal discovery process includes sending of a discovery signal and receiving of the discovery signal. The direct communication process includes a series of processes such as call initiation, channel measurement, channel feedback, resource scheduling, data transmission, and call completion.

    [0003] In the prior art, in a scenario in which a user device communicates with a base station, the user device measures channel quality and feeds back the channel quality to the base station, and the base station performs resource scheduling for the user device according to the channel quality fed back by the user device. When delivering resource scheduling signaling, the base station may further send a parameter required for data communication on a scheduled physical resource to the user device. In this way, after receiving the scheduling signaling, the user device can perform data communication on the scheduled resource.

    [0004] However, in a scenario of direct communication between user devices, a base station cannot learn information about a state of a channel between the user devices, and therefore cannot learn a parameter required for direct communication between the user devices. The user devices need to send a channel sounding signal to obtain the channel state information, to determine the parameter required for data communication. Therefore, when a resource for direct communication changes, communication currently performed between the user devices needs to be interrupted, to perform channel sounding to obtain the parameter required for data communication, which affects a direct communication service of the user devices.

    [0005] WO 2012/159270 A1 provides a mechanism for allocating communication resources of a cellular communication network to a D2D communication. After an eNB has configured a number of resource pools indicating a set of resources usable in the D2D communication, D2D clusters which share a same resource pool are enabled to obtain resources for their respective D2D communication. By detecting the current resource utilization state in the allocated resource pool by measurement on the UE side, it is decided whether suitable resources are available or not. An overload situation is signaled to the eNB if no suitable resource can be detected.

    SUMMARY

    DESCRIPTION OF EMBODIMENTS



    [0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

    [0018] Technologies described in this specification may be applied to various communications systems, for example, current 2G and 3G communications systems and a next-generation communications system, for example, a Global System for Mobile Communications (GSM, Global System for Mobile communications), a Code Division Multiple Access (CDMA, Code Division Multiple Access) system, a Time Division Multiple Access (TDMA, Time Division Multiple Access) system, a Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) system, a Frequency Division Multiple Access (FDMA, Frequency Division Multiple Access) system, an Orthogonal Frequency-Division Multiple Access (OFDMA, Orthogonal Frequency-Division Multiple Access) system, a single-carrier FDMA (SC-FDMA) system, a General Packet Radio Service (GPRS, General Packet Radio Service) system, a Long Term Evolution (LTE, Long Term Evolution) system, and other communications systems.

    [0019] A terminal in this application, that is, user equipment, may be a wireless terminal or a wired terminal. The wireless terminal may refer to a device that provides a user with voice and/or data connectivity, a handheld device with a radio connection function, or another processing device connected to a radio modem. The wireless terminal may communicate with one or more core networks through a radio access network (such as RAN, Radio Access Network). The wireless terminal may be a mobile terminal, such as a mobile phone (also referred to as a "cellular" phone) and a computer with a mobile terminal, for example, may be a portable, pocket-sized, handheld, computer built-in, or in-vehicle mobile apparatus, which exchanges voice and/or data with the radio access network. For example, it may be a device such as a personal communication service (PCS, Personal Communication Service) phone, a cordless telephone set, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL, Wireless Local Loop) station, or a personal digital assistant (PDA, Personal Digital Assistant). The wireless terminal may also be called a system, a subscriber unit (Subscriber Unit), a subscriber station (Subscriber Station), a mobile station (Mobile Station), a mobile terminal (Mobile), a remote station (Remote Station), an access point (Access Point), a remote terminal (Remote Terminal), an access terminal (Access Terminal), a user terminal (User Terminal), a user agent (User Agent), a user device (User Device), or a user equipment (User Equipment).

    [0020] A base station (for example, an access point) involved in this application may refer to a device on the access network that communicates with the wireless terminal on an air interface by using one or more sectors. The base station may be configured to mutually convert a received over-the-air frame and an IP packet and serve as a router between the wireless terminal and a rest portion of the access network, where the rest portion of the access network may include an Internet protocol (IP) network. The base station may also coordinate attribute management of the air interface. For example, the base station may be a base station (BTS, Base Transceiver Station) in GSM or the CDMA, may also be a base station (NodeB) in WCDMA, and may further be an evolved NodeB (NodeB, eNB, or e-NodeB, evolved Node B) in the LTE, which is not limited in the present application.

    [0021] In addition, the terms "system" and "network" may be used interchangeably in this specification. The term "and/or" in this specification describes only an association relationship for describing associated objects and represents that three relationships may exist. For example, A and/or B may represent the following three cases: Only A exists, both A and B exist, and only B exists. In addition, the character "/" in this specification generally indicates an "or" relationship between the associated objects.

    [0022] FIG. 1 is a flowchart of an embodiment of a resource allocation method for direct communication between user devices provided by the present invention. As shown in FIG. 1, the method includes:

    S101: A third device determines a first resource, where the first resource includes some or all of a second resource, the second resource is determined by the third device before the first resource is determined, and the first resource and the second resource are both used for communication between a first user device and a second user device.

    S102: The third device sends resource signaling to the first user device and/or the second user device, where the resource signaling carries information about the first resource.



    [0023] The foregoing steps are performed by the third device, where the third device may be a base station, may be a user device, or may be a device of another type except the first user device and the second user device.

    [0024] The method provided in this embodiment is applicable to an implementation scenario of direct communication between the first user device and the second user device. The first resource is a resource currently allocated by the third device for communication between the first user device and the second user device, and the second resource is a resource allocated by the third device for communication between the first user device and the second user device before the first resource is allocated. The information about the first resource may be frequency domain information and/or time domain information and the like of the first resource; and similarly, the information about the second resource may also be frequency domain information and/or time domain information and the like of the second resource.

    [0025] The first resource may include some or all of the second resource. The following provides description by using an example in which the first resource includes some of the second resource: The second resource that is allocated by the third device for communication between the first user device and the second user device before the first resource is allocated (that is, the second resource allocated last time prior to the first resource that is currently allocated) includes a resource A and a resource B. The first user device and the second user device that participate in direct communication both learn channel state information of the resource A and the resource B, and the first user device and the second user device perform direct communication on the resource A and the resource B; therefore, direct communication can be performed on the resource A and the resource B. When the third device schedules a new resource, the first resource allocated by the third device for communication between the first user device and the second user device includes the resource B and a resource C. The resource B is not only included in the second resource that is allocated by the third device before the first resource is allocated, but also included in the first resource that is currently allocated by the third device. Therefore, for the new resource C, the first user device and the second user device need to perform channel sounding for a period of time to obtain channel state information. However, during this period of time, the first user device and the second user device can continue to perform direct communication by using the resource B, to ensure that communication proceeds normally without interruption.

    [0026] The third device may send the resource signaling to either or both of the first user device and the second user device. However, it should be noted that, in the implementation scenario in this embodiment, if the first resource currently allocated by the third device does not include any resource in the second resource, after the first user device and/or the second user device receives the resource signaling, it may be considered that the first resource currently allocated by the third device is an erroneous configuration. The direct communication can still be performed between the first user device and the second user device by using the second resource that is allocated by the third device before the first resource is allocated.

    [0027] This embodiment provides a resource allocation method for direct communication between user devices, where a first resource allocated by a third device for communication between a first user device and a second user device includes some or all of a second resource that is allocated by the third device before the first resource is allocated, so that when a resource for direct communication changes, a normal direct communication service between the user devices is ensured.

    [0028] FIG. 2 is a flowchart of another embodiment of a resource allocation method for direct communication between user devices provided by the present invention. As shown in FIG. 2, the method includes:

    S201: A first user device receives resource signaling sent by a third device, where the resource signaling carries information about a first resource determined by the third device, the first resource includes some or all of a second resource, the second resource is determined by the third device before the first resource is determined, and the first resource and the second resource are both used for communication between the first user device and a second user device.

    S202: The first user device determines, according to the information about the first resource, that the first resource is used for communication with the second user device.



    [0029] It should be noted that, the first user device that performs the foregoing steps in this embodiment may be either user device in two user devices that perform direct communication, that is, the two user devices that perform direct communication both can receive the resource signaling sent by the third device.

    [0030] For S201 and S202, reference may be made to relevant descriptions in S101 and S102. It should be noted that, if the first resource that is carried in the resource signaling received by the first user device includes some or all of the second resource, where the second resource is allocated by the third device for communication between the first user device and the second user device before the first resource is allocated, the first user device may use the first resource according to the information about the first resource. Specifically, the following is included: During a period of time in which the first user device and the second user device perform channel sounding to obtain channel state information of a new resource (which refers to another resource in the first resource except the included second resource), direct communication is performed by using the second resource included in the first resource, to ensure that the communication proceeds normally without interruption. After the channel state information of the new resource is obtained through channel sounding, direct communication is performed by using the first resource.

    [0031] This embodiment provides a resource allocation method for direct communication between user devices, where a first resource that is received by the first user device and allocated by a third device for communication between a first user device and a second user device includes some or all of a second resource that is allocated by the third device before the first resource is allocated, so that when a resource for direct communication changes, a normal direct communication service between the user devices is ensured.

    [0032] FIG. 3 is a flowchart of still another embodiment of a resource allocation method for direct communication between user devices provided by the present invention. As shown in FIG. 3, the method includes:

    S301: A first user device receives first resource signaling sent by a third device, where the first resource signaling carries information about a first resource determined by the third device.

    S302: When determining that the first resource does not include some or all of a second resource, the first user device determines that a resource used for communication with a second user device is the first resource and the second resource or is the second resource, where the second resource is determined by the third device before the first resource is determined, and the first resource and the second resource are both used for communication between the first user device and the second user device.



    [0033] It should be noted that, the first user device that performs the foregoing steps in this embodiment may be either user device in two user devices that perform direct communication, that is, the two user devices that perform direct communication both can receive the resource signaling sent by the third device.

    [0034] Similar to the first resource signaling, before receiving the first resource signaling, the first user device receives second resource signaling sent by the third device, where the second resource signaling carries information about the second resource allocated by the third device for communication between the first user device and the second user device.

    [0035] When the third device schedules a new resource for the first user device, the first user device receives the first resource signaling sent by the third device, where the first resource signaling carries the information about the first resource allocated by the third device for communication between the first user device and the second user device.

    [0036] If the first resource currently allocated by the third device does not include some or all of the second resource allocated by the third device for communication between the first user device and the second user device before the first resource is allocated, for example, the second resources previously allocated by the third device are a resource A and a resource B, and the currently allocated first resources are a resource C and a resource D. In this implementation scenario, as a feasible implementation manner, the third device and the user device that receives the first resource signaling in direct communication determine that a resource used for communication with the second user device is the first resource and the second resource or is the second resource.

    [0037] Optionally, when determining that the to-be-used resources are the first resource and the second resource, the first user device may further start a preset timer (timer), where resources used for communication between the first user device and the second user device within timing duration are the first resource and the second resource, and the second resource is not used after the timing duration elapses. That is, the resource allocated before the first resource is allocated is valid only within a period of time. For example, the resource A and the resource B that are scheduled before the first resource is allocated are valid only within a period of time, and after the timing duration of the timer elapses, only the resource C and the resource D are used for direct communication between the first user device and the second user device. It should be noted that, the timing duration of the timer generally needs to be greater than a time length used by the first user device and the second user device to obtain, through channel sounding, channel state information of a new resource (the resource C and the resource D). After the timing duration of the timer elapses, the resource used for communication with the second user device is the first resource.

    [0038] If the first resource currently allocated by the third device does not include some or all of the second resource allocated by the third device for communication between the first user device and the second user device before the first resource is allocated, in another feasible implementation manner, the first user device determines that a resource used in direct communication with the second user device is the second resource. In this implementation scenario, the third device and the user device that receives the first resource signaling in direct communication determine that direct communication is performed by still using the second resource that is allocated by the third device before the first resource is allocated.

    [0039] This embodiment provides a resource allocation method for direct communication between user devices. If a first resource currently allocated by a third device does not include some or all of a second resource that is allocated by the third device before the first resource is allocated, it is determined that a resource used for communication with a second user device is the first resource and the second resource or is the second resource, so that when a resource for direct communication changes, a normal direct communication service between the user devices is ensured.
