The method of the embodiment of fig. 3 is specifically described below by taking fig. 8 as an example.
Step 81, for downlink data transmission, the access network device sends first data to the terminal device in time unit n of the first carrier, and the terminal device also receives the first data from the access network device in time unit n of the first carrier. For uplink data transmission, the terminal device sends the first data to the access network device in time unit n of the first carrier, and the access network device also receives the first data from the terminal device in time unit n of the first carrier. For sidestream data transmission, the terminal device transmits the first data to other terminal devices in time unit n of the first carrier, and the other terminal devices also receive the first data from the terminal devices in time unit n of the first carrier.
Step 82, the access network device determines a second time unit of the second carrier according to the time unit n of the first carrier, the first parameter k and the first time length.
And step 83, the terminal device determines a second time unit of the second carrier according to the first time unit of the first carrier, the first parameter k and the first time length.
In step 82 or step 83, the first parameter k is a preset parameter, or the first parameter k is a parameter included in the first control information and is sent by the access network device to the terminal device, where the first parameter k is 0 or a positive integer. The first duration is a time length of a time unit n of the first carrier or a time length of a second time unit of the second carrier. The time lengths of the time units n, n +1 to n +5 of the first carrier are equal, the time lengths of the time units m to m +11 of the second carrier are equal, but the time lengths of the time units n, n +1 to n +5 of the first carrier are different from the time lengths of the time units m to m +11 of the second carrier. Optionally, the first time length may be different from a time length of the time unit n of the first carrier or a time length of the second time unit of the second carrier, for example, if the time unit n of the first carrier is a time slot, the first time length may be a micro time slot, and if the time unit m of the second carrier is a micro time slot, the first time length may be a symbol, and so on. Optionally, the sequence of step 82 and step 83 is not limited.
In an optional embodiment, the access network device or the terminal device determines that the termination time of the time unit n is shifted backward by a first time length as the first time, where the first time length is obtained by multiplying the first parameter k by the first duration. For example, in fig. 8, the first parameter k is 4, and the first duration is the time length of the time unit n of the first carrier, so the first time in fig. 8 is a time at which the termination time of the time unit n of the first carrier is shifted backward by the time lengths of the time units of the 4 first carriers.
And the access network equipment or the terminal equipment determines a second time unit of the second carrier according to the first time. Optionally, the access network device or the terminal device determines that a time unit m +9 corresponding to the first time on the second carrier is the second time unit. Optionally, the access network device or the terminal device determines that time unit m +9 corresponding to the first time on the second carrier is the third time unit, and the access network device or the terminal device determines that the next time unit m +10 of m +9 is the second time unit. Then, in the downlink data transmission, the terminal device sends feedback information to the access network device at a second time unit of the second carrier. In uplink data transmission, the access network equipment sends feedback information to the terminal equipment in a second time unit of a second carrier. In the V2X sidelink data transmission, the terminal device sends feedback information to the access network device at the second time unit of the second carrier. Optionally, the feedback information may be received by the terminal device from the other terminal devices. Optionally, the feedback information may also be determined by the terminal device after receiving the first data from the other terminal device, so as to indicate whether the terminal device has successfully received the first data from the other terminal device.
In an optional embodiment, second data between the access network device and the terminal device or between the terminal devices is transmitted on a time unit n of the first carrier, the access network device or the terminal device determines a time unit m +9 of the second carrier as a transmission unit of the feedback information according to the time unit n, the first parameter, and the first duration, and the second data between the access network device and the terminal device or between the terminal devices is transmitted on a time unit n +1 of the first carrier, the access network device or the terminal device determines a time unit m +9 of the second carrier as a transmission unit of the feedback information according to the time unit n +1, the second parameter, and the second duration, and then the time unit m +9 of the second carrier is used for the transmission unit of the feedback information of the first data and the second data.
For another example, in fig. 9, the first parameter k is 4, and the first duration is the time length of the time unit m of the second carrier, so the first time in fig. 9 is a time at which the termination time of the time unit n of the first carrier is shifted backward by the time length of the time unit m of the 4 second carriers. In fig. 9 the length of the time unit of the first carrier is equal to 2 times the length of the time unit of the second carrier, and therefore the length of the time unit of the 4 second carriers is equal to the length of the time unit of the 2 first carriers.
And the access network equipment or the terminal equipment determines a second time unit of the second carrier according to the first time. Optionally, the access network device or the terminal device determines that a time unit m +5 corresponding to the first time on the second carrier is the second time unit. Optionally, the access network device or the terminal device determines that time unit m +5 corresponding to the first time on the second carrier is the third time unit, and the access network device or the terminal device determines that the next time unit m +6 of m +5 is the second time unit. Then, in the downlink data transmission, the terminal device sends feedback information to the access network device at a second time unit of the second carrier. In uplink data transmission, the access network equipment sends feedback information to the terminal equipment in a second time unit of a second carrier. In the V2X sidelink data transmission, the terminal device sends feedback information to the access network device at the second time unit of the second carrier. Optionally, the feedback information may be received by the terminal device from the other terminal devices. Optionally, the feedback information may also be determined by the terminal device after receiving the first data from the other terminal device, so as to indicate whether the terminal device has successfully received the first data from the other terminal device.
In an alternative embodiment, in fig. 8 or fig. 9, the access network device or the terminal device determines, as a new second time unit, a time unit of the second carrier after the second time unit is shifted backward by the time length of the first offset. The first offset may be a specific time length, or a number of subframes, slots, minislots, or symbols, and optionally, the control information may also be used to indicate a time unit or granularity of the first offset, such as which subframe, slot, minislot, or symbol is, and the first offset may also be indication information used to indicate a time length of the offset. The first offset may be a preset offset, and the first offset may also be included in control information sent by the access network device to the terminal device, for example, included in downlink control information. For example, in the case that there is no first offset, the access network device or the terminal device determines that m +9 of the second carrier is the second time unit, and the first offset is the time unit length of 2 second carriers, then the access network device or the terminal device determines that m +11 of the second carrier is the second time unit. Optionally, the access network device or the terminal device shifts the first time backward by the first offset to obtain a second time, and then the access network device or the terminal device determines a second time unit corresponding to the second time on a second carrier according to the second time. The first offset may be determined by the access network device according to at least one of the number of the terminal devices, the priority of the data to be transmitted, the channel condition, and the amount of the data to be transmitted. The access network device determines a second time unit of the second carrier for data transmission to different terminal devices according to different offsets, so that the second carrier can be more effectively utilized in a time domain, and resource waste is avoided.
In an alternative embodiment, the time units n to n +5 of the first carrier are at least one of subframes, slots, minislots, and symbols, and the time units m to m +11 of the second carrier are at least one of subframes, slots, minislots, and symbols.
In an alternative embodiment, if the first time determined by the access network device or the terminal device according to the foregoing method is a start time or an end time of a time unit of the second carrier, the access network device or the terminal device determines a time unit before the first time as the second time unit, or the access network device or the terminal device determines a time unit after the first time as the second time unit. For example, in fig. 8, the first time is a termination time of the time unit m +9 of the second carrier, that is, the first time is a start time of the time unit m +10 of the second carrier, and then the access network device or the terminal device determines that the time unit m +9 or m +10 of the second carrier is the second time unit, and this second time unit is used for the access network device or the terminal device to receive or send the feedback information.
Step 84, the access network device transmits feedback information with the terminal device at the second time unit of the second carrier, where the feedback information is used to feed back the transmission state of the first data.
In this embodiment of the present application, although the lengths of the time units of the first carrier and the second carrier are different, that is, the granularity of the first carrier and the second carrier is different in the time domain, the access network device or the terminal device may shift the time unit for sending data in the first carrier backward by a first time length k times to determine that the second time unit of the second carrier is used as the time unit for transmitting the feedback information, since the first time length may be the length of the time unit in the first carrier, may also be the length of the time unit in the second carrier, or may also be another time length (for example, one of a subframe, a time slot, a micro-slot, and a symbol) other than the length of the time unit in the first carrier or the second carrier, the access network device or the terminal device may determine the second time unit of the second carrier according to the time unit n of the first carrier, the first parameter k, and the first time length for transmitting the feedback information, namely, the transmission of data and feedback information between carriers with different time unit lengths is realized.
