Transmission method and terminal device
View Patent ↗A transmission method and a terminal device are provided. The transmission method includes: when configuring a configured grant retransmission timer, a terminal device determining a hybrid automatic repeat request process and/or the state of the timer on the basis of a satisfied condition. By means of the embodiments of the present application, the transmission delay of a resource, especially a low-priority resource, can be reduced.
1 . A method for transmission, applied to a New Radio Unlicensed (NRU) scenario, comprising:
receiving, by a terminal device, a Configured Grant (CG) resource, wherein the CG resource comprises configuration information, and the configuration information comprises CG timer, CG Retransmission (retx) Timer, and autonomous TX;
in a case of the CG resource being a deprioritized resource and the CG timer and the CG retx Timer being running, stopping the CG timer and stopping the CG retx Timer, wherein the deprioritized resource is not transmitted by the terminal in at least one of following cases:
the CG resource is conflicted with a CG resource;
the CG resource is conflicted with a Dynamic Grant (DG) resource;
the CG resource is conflicted with a Scheduling Request (SR) resource;
the DG resource is conflicted with the SR resource; and
uplink grant is conflicted with a Physical Uplink Control Channel (PUCCH) resource;
whereinin in repsonse to the CG resource is a previous resource corresponding to a Hybrid Automatic Repeat Request (HARQ) process and a Medium Access Control (MAC) Protocol Data Unit (PDU) is acquired, a subsequent CG resource corresponding to the HARQ process is used to perform automatic transmission.
2 . The method of claim 1 , wherein the configuration information further comprises:
one or more HARQ process identifiers corresponding to the CG resource.
3 . The method of claim 1 , further comprising:
transmitting, by the terminal device, a prioritized resource in at least one of following cases:
the CG resource is conflicted with a CG resource;
the CG resource is conflicted with a Dynamic Grant (DG) resource;
the CG resource is conflicted with a Scheduling Request (SR) resource;
the DG resource is conflicted with the SR resource; and
uplink grant is conflicted with a Physical Uplink Control Channel (PUCCH) resource.
4 . The method of claim 1 , wherein the CG resource corresponds to a deprioritized MAC PDU.
5 . The method of claim 1 , wherein Ultra-Reliable and Low Latency Communication (URLLC) automatic transmission is used.
6 . The method of claim 1 , wherein the CG timer and the CG retx Timer are started at or after an end of a last symbol of a PUSCH resource when the PUSCH resource is a deprioritized resource.
7 . A terminal device, applied to a New Radio Unlicensed (NRU) scenario, comprising a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to invoke and run the computer program stored in the memory to cause the terminal device to perform:
receiving a CG resource, wherein the CG resource comprises configuration information, and the configuration information comprises CG timer, CG retx Timer, and autonomous TX;
in a case of the CG resource being a deprioritized resource and the CG timer and the CG retx Timer being running, stopping the CG timer and stopping the CG retx Timer, wherein the deprioritized resource is not transmitted by the terminal in at least one of following cases:
the CG resource is conflicted with a CG resource;
the CG resource is conflicted with a Dynamic Grant (DG) resource;
the CG resource is conflicted with a Scheduling Request (SR) resource;
the DG resource is conflicted with the SR resource; and
uplink grant is conflicted with a Physical Uplink Control Channel (PUCCH) resource;
wherein in response to the CG resource is a previous resource corresponding to a Hybrid Automatic Repeat Request (HARQ) process and a Medium Access Control (MAC) Protocol Data Unit (PDU) is acquired, a subsequent CG resource corresponding to the HARQ process is used to perform automatic transmission.
8 . The terminal device of claim 7 , wherein the configuration information further comprises:
one or more HARQ process identifiers corresponding to the CG resource.
9 . The terminal device of claim 7 , wherein the terminal device is further caused to perform:
transmitting a prioritized resource in at least one of following cases:
the CG resource is conflicted with a CG resource;
the CG resource is conflicted with a Dynamic Grant (DG) resource;
the CG resource is conflicted with a Scheduling Request (SR) resource;
the DG resource is conflicted with the SR resource; and
uplink grant is conflicted with a Physical Uplink Control Channel (PUCCH) resource.
10 . The terminal device of claim 7 , wherein the CG resource corresponds to a deprioritized MAC PDU.
11 . The terminal device of claim 7 , wherein Ultra-Reliable and Low Latency Communication (URLLC) automatic transmission is used.
12 . The terminal device of claim 7 , The method of claim 1 , wherein the CG timer and the CG retx Timer are started at or after an end of a last symbol of a PUSCH resource when the PUSCH resource is a deprioritized resource.
13 . A non-transitory computer-readable storage medium for storing a computer program, wherein when the computer program is run by a device, the device performs a method, applied to a New Radio Unlicensed (NRU) scenario, comprising:
receiving a CG resource, wherein the CG resource comprises configuration information, and the configuration information comprises CG timer, CG retx Timer, and autonomous TX;
in a case of the CG resource being a deprioritized resource and the CG timer and the CG retx Timer being running, stopping the CG timer and stopping the CG retx Timer, wherein the deprioritized resource is not transmitted by the terminal in at least one of following cases:
the CG resource is conflicted with a CG resource;
the CG resource is conflicted with a Dynamic Grant (DG) resource;
the CG resource is conflicted with a Scheduling Request (SR) resource;
the DG resource is conflicted with the SR resource; and
uplink grant is conflicted with a Physical Uplink Control Channel (PUCCH) resource;
wherein in response to the CG resource is a previous resource correpsonding to a Hybrid Automatic Repeat Request (HARQ) process and a Medium Access Control (MAC) Protocol Data Unit (PDU) is acquired, a subsequent CG resource corresponding to the HARQ process is used to perform automatic transmission.
14 . The non-transitory computer-readable storage medium of claim 13 , wherein the configuration information further comprises:
one or more HARQ process identifiers corresponding to the CG resource.
15 . The non-transitory computer-readable storage medium of claim 13 , wherein the method further comprises:
transmitting, by the terminal device, a prioritized resource in at least one of following cases:
