    Description

    TECHNICAL FIELD



    [0001] Embodiments of the disclosure relate to the field of communications, and more particularly to an information transmission method and a device. The features of the preamble of the independent claims are known from EP 2056616A1 and US 2004/042492A1.

    BACKGROUND



    [0002] Along with continuous extension of an air interface technology and application, reducing a delay becomes one of key performance indicators in a future communication technology. For example, an end-to-end delay of real-time remote computing for mobile terminals is less than 10ms, a delay of traffic efficiency and safety is required to be less than 5ms, and a duration of a Transmission Time Interval (TTI) of the existing Long Term Evolution (LTE) is 1ms.

    [0003] A data processing and decoding delay is mainly related to a TTI. Therefore, one of key technologies for reducing a transmission delay is to shorten a TTI. At present, LTE-Advanced Release 13 (LTE-A Rel-13) has determined to start making researches on data transmission with a shorter TTI. However, compatibility with an existing LTE system is required to be ensured on a carrier supporting short-TTI transmission, that is, compatibility with a 1ms TTI is simultaneously required. A short TTI has the advantage of shortening a transmission delay, but also has the corresponding cost of high control signaling overhead and low spectrum efficiency.

    [0004] Considering that uplink and downlink service delay requirements may be different and coverage of uplink transmission may be relatively poor, a system may support use of different TTIs for uplink and downlink. Therefore, a method for determining a scheduling and feedback time sequence during use of different TTIs for uplink and downlink is required.

    DETAILED DESCRIPTION



    [0038] The technical solutions in the embodiments of the disclosure will be clearly and completely described below in combination with the drawings in the embodiments of the disclosure. Obviously, the described embodiments are not all embodiments but part of embodiments of the disclosure. All other embodiments obtained by those skilled in the art on the basis of the embodiments in the disclosure without creative work shall fall within the scope of the claims. The embodiments not falling within the scope of claims shall be treated as examples suitable for understanding the invention.

    [0039] FIG. 1 is a schematic flowchart of an information transmission method 100 according to an embodiment of the disclosure. As illustrated in FIG. 1, the method 100 includes the following operations.

    [0040] In S110, a sending end device sends first information to a receiving end device.

    [0041] Specifically, the sending end device sends the first information to the receiving end device in a first time unit n (n is an index of the first time unit). A duration of the first time unit is a first TTI, and the receiving end device may determine the duration of the first time unit according to a system default rule, or the receiving end device may also determine the duration of the first time unit according to indication information sent by the sending end device.

    [0042] In S120, the receiving end device sends second information for the first information to the sending end device.

    [0043] Specifically, the receiving end device may send the second information for the first information to the sending end device in a second time unit k (k is an index of the second time unit) after receiving the first information sent by the sending end device. A duration of the second time unit is a second TTI, and the second TTI is different from the first TTI. The receiving end device may determine a time interval between the second time unit k and the first time unit n according to the system default rule, or may also determine the time interval between the second time unit k and the first time unit n according to the indication information sent by the sending end device.

    [0044] Alternatively, as an embodiment, when the receiving end device is terminal equipment (or called as user equipment), the corresponding sending end device is a base station, and if the terminal equipment receives downlink data sent on a Physical Downlink Control Channel (PDCCH) in the first time unit n, the terminal equipment may send feedback information for indicating whether the terminal equipment successfully receives the downlink data to the base station in the second time unit k. The feedback information may be, for example, an Acknowledgement (ACK)/Negative ACK (NACK).

    [0045] Alternatively, as an embodiment, when the receiving end device is a base station, the corresponding sending end device is terminal equipment. If the terminal equipment receives downlink control signaling for scheduling transmission of uplink data of the terminal equipment, for example, an uplink grant (UL Grant), from the base station in the first time unit n, the terminal equipment may send the uplink data to the base station in a PUSCH in the second time unit n.

    [0046] Alternatively, as an embodiment, the second time unit k is a first one of second time units after a target time length since a starting moment of the first time unit n, wherein the target time length is an integral multiple of the duration of the first time unit n. For example, as illustrated in FIG. 2, a time interval between a starting moment of the second time unit k and the starting moment of the first time unit n is 4 times the duration of the first time unit.

    [0047] Alternatively, as an embodiment, a subframe includes M first time units, an ending moment of the ith first time unit in the M first time units is before a starting moment of the (i+1)th first time unit, or, the ending moment of the ith first time unit is the starting moment of the (i+1)th first time unit, wherein M is a positive integer more than or equal to 1, i is set to be 0 when M is 1, and i is a positive integer and 1≤i≤M-1 when M>1; and
    a subframe includes N second time units, an ending moment of the kth second time unit in the N second time units is before a starting moment of the (k+1)th second time unit, or, the ending moment of the kth second time unit in the N second time units is the starting moment of the (k+1)th second time unit, wherein N is a positive integer more than or equal to 1, k is set to be 0 when N is 1, and k is a positive integer and 1≤k≤N-1 when N>1.

    [0048] That is, 1ms duration of an existing subframe may include one or more first time units, and the 1ms duration of the existing subframe may include one or more second time units.

    [0049] Specifically, as an embodiment, the value of N is 1, and the value of M is 2. That is, for an FDD system, the first time unit is an LTE timeslot, and the second time unit is an LTE subframe. As illustrated in FIG. 3, for example, for transmission of downlink data, the downlink data is transmitted in time unit of a timeslot, i.e., 0.5ms TTI, and ACK/NACK information is transmitted in time unit of a subframe, i.e., 1ms TTI. Assume that a processing delay specified by a system is N times a TTI corresponding to data transmission. When a value of N is 4, if the receiving end device receives the downlink data in a timeslot 0 of a subframe a, the ACK/NACK information corresponding to the downlink data is transmitted in a subframe a+2; and if the receiving end device receives the downlink data in a timeslot 1 of the subframe a, the ACK/NACK information corresponding to the downlink data is transmitted in a subframe a+3.

    [0050] Alternatively, as an embodiment, the value of N is 1, and M is a positive integer more than or equal to 3. That is, for the FDD system, a subframe includes three or more than three first time units, and the second time unit is a subframe. As illustrated in FIG. 4, for example, for transmission of the downlink data, a subframe includes 3 time units (first time units) for transmitting the downlink data, and the ACK/NACK information is transmitted in time unit of a subframe, i.e., 1ms subframe. The processing delay specified by the system is N times the TTI corresponding to data transmission, N being a positive integer, and if N=4, specific feedback time of the ACK/NACK information is illustrated in FIG. 4.

    [0051] FIG. 5 is a schematic diagram of a downlink data and feedback information transmission time sequence when a timeslot includes two time units for transmitting downlink data and feedback information is transmitted in time unit of a subframe. Assume that the processing delay specified by the system is 4 times the TTI corresponding to data transmission. When the receiving end device receives the downlink data in a first one of first time units of the subframe a, the receiving end device sends feedback information (ACK/NACK) for the downlink data to the sending end device in a subframe a+1; and when the receiving end device receives the downlink data in a second or third or fourth one of first time units of the subframe a, the receiving end device sends the feedback information for the downlink data to the sending end device in the subframe a+2.

    [0052] Alternatively, as an embodiment, the value of M is 1, and N is a positive integer more than or equal to 2. That is, for the FDD system, a subframe includes one first time unit, and a subframe includes at least two second time units. As illustrated in FIG. 6, for example, for transmission of the downlink data, assume that the processing delay specified by the system is 4 times the TTI corresponding to data transmission.
