Methods and devices for resource allocation
Methods and devices for resource allocation are provided. The method includes the following. A first terminal receives BSR information from a second terminal. The first terminal allocates a first transmission resource to the second terminal.
1. A method for resource allocation, comprising:
receiving, by a first terminal, buffer status report (BSR) information from a second terminal;
receiving, by the first terminal, first information from the second terminal, wherein the first information comprises a candidate transmission resource indicator, wherein the candidate transmission resource indicator is for indicating available transmission resource that is in a first resource selection window; and
allocating, by the first terminal, a first transmission resource to the second terminal based on the BSR information and the first information.
2. The method of claim 1 , wherein receiving, by the first terminal, BSR information from the second terminal comprises:
receiving, by the first terminal, first sidelink (SL) transmission channel transmitted by the second terminal, wherein the BSR information is carried by the first SL transmission channel.
3. The method of claim 2 , wherein the first SL transmission channel is a first SL control channel, and the BSR information is carried by first SL control information that is carried in the first SL control channel.
4. The method of claim 2 , wherein the first SL transmission channel is a first SL data channel, and the BSR information is carried by data that is carried in the first SL data channel.
5. The method of claim 3 , wherein the first SL control information carries a third information field, and the third information field is for indicating that the first SL control information carries scheduling request (SR) information.
6. The method of claim 3 , wherein the first SL control information carries a fourth information field, and the fourth information field is for indicating SR information.
7. The method of claim 4 , wherein SR information is carried by data that is carried in the first SL data channel.
8. The method of claim 1 , further comprising:
receiving, by the first terminal, a second SL transmission channel transmitted by the second terminal, wherein SR information is carried by the second SL transmission channel.
9. The method of claim 1 ,
wherein the first information further comprises at least one of: a channel quality indicator (CQI), channel state information (CSI), or a modulation and coding scheme (MCS).
10. The method of claim 9 , further comprising:
determining, by the first terminal, the first resource selection window according to one of:
pre-configuration information;
network configuration information; or
configuration information received from a third terminal.
11. A method of resource allocation, comprising:
transmitting, by a second terminal, buffer status report (BSR) information to a first terminal, the BSR information being used for the first terminal to allocate a first transmission resource to the second terminal; and
transmitting, by the second terminal, first information to the first terminal, wherein the first information comprises a candidate transmission resource indicator, wherein the candidate transmission resource indicator is for indicating available transmission resource that is in a first resource selection window.
12. A device for resource allocation, comprising:
a transceiver;
at least one processor; and
a memory storing instructions which, when executed by the at least one processor, cause the transceiver to:
receive buffer status report (BSR) information from a terminal; and
receive first information from the terminal, wherein the first information comprises a candidate transmission resource indicator, wherein the candidate transmission resource indicator is for indicating available transmission resource that is in a first resource selection window;
the instructions, when executed by the at least one processor, cause the processor to:
allocate a first transmission resource to the terminal based on the BSR information and the first information.
13. The device of claim 12 , wherein the transceiver is configured to receive a first sidelink (SL) transmission channel transmitted by the terminal, wherein the BSR information is carried by the first SL transmission channel.
14. The device of claim 13 , wherein the first SL transmission channel is a first SL control channel, and the BSR information is carried by first SL control information that is carried in the first SL control channel.
15. The device of claim 13 , wherein the first SL transmission channel is a first SL data channel, and the BSR information is carried by data that is carried in the first SL data channel.
16. The device of claim 14 , wherein the first SL control information carries a third information field, and the third information field is for indicating that the first SL control information carries scheduling request (SR) information.
17. The device of claim 14 , wherein the first SL control information carries a fourth information field, and the fourth information field is for indicating SR information.
18. The device of claim 15 , wherein SR information is carried by data that is carried in the first SL data channel.
19. The device of claim 12 , wherein the transceiver is further configured to receive a second SL transmission channel transmitted by the terminal, wherein SR information is carried by the second SL transmission channel.
20. The device of claim 12 , wherein the first information further comprises at least one of: a channel quality indicator (CQI), channel state information (CSI), or a modulation and coding scheme(MCS).
