Description

第1のデバイスが第1の期間に第2の情報を受信しない場合、第1のデバイスは第4のデバイスに第1の情報を送信し、または第1のデバイスは第2のデバイスに第1の情報を送信し、または第1のデバイスはリソース支援情報を使用せずに通信リソースを決定し、または第1のデバイスはもはや第2の情報を受信するのを待機せず、または第1のデバイスは第1の情報を再送する。第2の情報は、第2のデバイスが第1のデバイスにリソース支援情報を提供することを示し、または第2の情報は、第2のデバイスが第1のデバイスにリソース支援情報を提供するかどうかを示すために特に使用される。または第2の情報はリソース支援情報である。 If the first device does not receive the second information in the first period, the first device transmits the first information to the fourth device, or the first device transmits the first information to the second device, or the first device determines the communication resource without using the resource assistance information, or the first device no longer waits to receive the second information, or the first device resends the first information. The second information indicates that the second device provides resource assistance information to the first device, or the second information is specifically used to indicate whether the second device provides resource assistance information to the first device. Or the second information is resource assistance information.

Claims

receiving, by a first apparatus , second information from a second device, the second information indicating resource assistance information provided by the second device, the second information being carried by a physical sidelink feedback channel (PSFCH);
determining, by the first device , a communication resource according to the resource assistance information.

2. The method of claim 1 , wherein the second information corresponds to a third sequence cyclic shift value of the PSFCH .

The method of claim 2 , wherein the sequence cyclic shift value of the resource assistance information is zero.

the second information is carried on a first resource set, the first resource set being a complementary set of a resource set used to carry hybrid automatic repeat request (HARQ) information and included in a resource set used to transmit the PSFCH ;
4. The method according to any one of claims 1 to 3 .

prior to the step of receiving, by the first apparatus, second information from the second device;
transmitting, by the first apparatus, first information to the second device, the first information being used to request obtaining the resource assistance information;
5. The method of claim 1, further comprising:

the step of transmitting, by the first device, first information includes transmitting, by the first device, the first information in a first slot;
the step of receiving, by the first device, the second information includes receiving, by the first device, the second information in a second slot;
The second slot is the first slot that includes the PSFCH and is located after the slot in which the last symbol of the first information is located, or the second slot is the first slot that includes the PSFCH and is located at an interval of N time units from the first slot, where N is a positive integer.
The method of claim 5 .

The method of any one of claims 1 to 6, wherein the resources carrying the resource assistance information are different from the resources carrying the HARQ information.

The method of any one of claims 1 to 7, wherein the resource assistance information is carried on a first resource set and the HARQ information is carried on a second resource set.

The method of claim 8, wherein the first resource set and the second resource set are represented using different bitmaps.

transmitting, by a second apparatus , second information to a first device, the second information indicating resource assistance information to the first device, the second information being carried by a physical sidelink feedback channel (PSFCH) .

11. The method of claim 10 , wherein the second information corresponds to a third sequence cyclic shift value of the PSFCH .

The method of claim 11 , wherein the sequence cyclic shift value of the resource assistance information is zero.

the second information is carried on a first resource set, the first resource set being a complementary set of a resource set used to carry hybrid automatic repeat request (HARQ) information and included in a resource set used to transmit the PSFCH ;
13. The method according to any one of claims 10 to 12 .

prior to the step of transmitting, by the second apparatus, the second information to the first device;
receiving, by the second apparatus, first information from the first device, the first information being used to request obtaining the resource assistance information;
14. The method of any one of claims 10 to 13, further comprising:

the step of receiving, by the second device, first information includes receiving, by the second device, the first information in a first slot;
the step of transmitting, by a second device, the second information includes transmitting, by the second device, the second information in a second slot;
The second slot is the first slot that includes the PSFCH and is located after the slot in which the last symbol of the first information is located, or the second slot is the first slot that includes the PSFCH and is located at an interval of N time units from the first slot, where N is a positive integer.
The method of claim 14 .

16. The method according to claim 10, wherein the resources carrying the resource assistance information are different from the resources carrying HARQ information.

17. The method according to claim 10 , wherein the resource assistance information is carried on a first resource set and HARQ information is carried on a second resource set.

20. The method of claim 17 , wherein the first resource set and the second resource set are represented using different bitmaps.

Apparatus comprising a processor configured to carry out the method according to any one of claims 1 to 9 or any one of claims 10 to 18 .

A computer-readable storage medium storing a computer program, the computer-readable storage medium storing a computer program which, when executed, performs the method according to any one of claims 1 to 9 or any one of claims 10 to 18 .

A computer program comprising instructions which, when executed by a computer, cause the computer to carry out the method according to any one of claims 1 to 9 or any one of claims 10 to 18 .
