Uplink information transmission method, terminal device, and access network device
An uplink information transmission method, a terminal device, and an access network device are provided. The method includes: obtaining, by a terminal device, indication information for sending uplink information on a first symbol set of a target carrier; and sending, by the terminal device, the uplink information in a second time in a time occupied by the first symbol set. The second time is a time in the time occupied by the first symbol set other than a first time, and is a time in which the terminal device is allowed to access a channel of the target carrier to send the uplink information.
1. A method, performed by a terminal device, the method comprising:
receiving, from a base station, an uplink scheduling grant, the uplink scheduling grant indicating at least two consecutive subframes comprising a first subframe and a second subframe, the first subframe is adjacent to the second subframe, and the second subframe is located before the first subframe;
detecting, in a second time period, that the terminal device is not allowed to access a channel in the second subframe, the second time period being comprised in a starting symbol of the second subframe;
detecting, in a first time period, that the terminal device is allowed to access the channel in the first subframe, wherein the first time period being comprised in a last symbol of the second subframe; and
transmitting uplink information to the base station in the first subframe.
2. The method according to claim 1 , wherein the uplink information comprises a sounding reference signal (SRS) and/or a physical uplink shared channel (PUSCH).
3. The method according to claim 1 , wherein the second subframe is a starting subframe of the at least two consecutive subframes.
4. An apparatus comprising:
a memory storage comprising instructions; and
one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to:
cooperate with a receiver to receive, from a base station, an uplink scheduling grant, the uplink scheduling grant indicating at least two consecutive subframes comprising a first subframe and a second subframe, the first subframe is adjacent to the second subframe, and the second subframe is located before the first subframe;
detect, in a second time period, that the terminal device is not allowed to access a channel in the second subframe, the second time period being comprised in a starting symbol of the second subframe;
detect, in a first time period, that the terminal device is allowed to access a channel in the first subframe, wherein the first time period being comprised in a last symbol of the second subframe; and
cooperate with a transmitter to transmit the uplink information to the base station in the first subframe.
5. The apparatus according to claim 4 , wherein the uplink information comprises a sounding reference signal (SRS) and/or a physical uplink shared channel (PUSCH).
6. The terminal device according to claim 4 , wherein the second subframe is a starting subframe of the at least two consecutive subframes.
7. A non-transitory computer-readable medium comprising processor-executable instructions which, when executed by a processor, cause the processor to implement operations for uplink information transmission, the operations including:
cooperating with a receiver to receive, from a base station, an uplink scheduling grant, the uplink scheduling grant indicating at least two consecutive subframes comprising a first subframe and a second subframe, the first subframe is adjacent to the second subframe, and the second subframe is located before the first subframe;
detecting, in a second time period, that the terminal device is not allowed to access a channel in the second subframe, the second time period being comprised in a starting symbol of the second subframe;
detecting, in a first time period, that the terminal device is allowed to access a channel in the first subframe, wherein the first time period being comprised in a last symbol of the second subframe; and
cooperating with a transmitter to transmit the uplink information to the base station in the first subframe.
8. The non-transitory computer-readable medium according to claim 7 , wherein the uplink information comprises a sounding reference signal (SRS) and/or a physical uplink shared channel (PUSCH).
9. The non-transitory computer-readable medium according to claim 7 , wherein the second subframe is a starting subframe of the at least two consecutive subframes.
