Abstract

The present application relates to a resource set transmission method, and terminals. The resource set transmission method comprises: a first terminal sends a transmission resource set to a second terminal, a transmission resource comprised in the transmission resource set being a transmission resource within a first time-frequency range. According to implementations of the present application, the time-frequency range of a transmission resource set can be accurately determined, so that the sending end and the receiving end of the resource set can determine the same time-frequency range, so as to determine the time-frequency location corresponding to a transmission resource in the transmission resource set, and perform correct resource selection according to the transmission resource in the transmission resource set.

First claim

What is claimed is:

1 . A transmission method of a resource set, comprising:
sending, by a first terminal, a transmission resource set to a second terminal, wherein a transmission resource included in the transmission resource set belongs to transmission resources in a first time-frequency range; wherein the first time-frequency range comprises a starting location of a frequency domain and an ending location of a frequency domain; wherein the starting location of the frequency domain and the ending location of the frequency domain are determined based on resource pool configuration information, wherein the resource pool configuration information comprises: an index of an initial sub-channel, a size of a sub-channel and a quantity of sub-channels of a resource pool.

2 . The method of claim 1 , wherein the first time-frequency range comprises a starting location of a time domain and an ending location of a time domain.

3 . The method of claim 2 , wherein the starting location of the time domain and/or the ending location of the time domain are determined based on first indication information sent by the first terminal.

4 . The method of claim 3 , wherein the first indication information is carried in sidelink control information (SCI), or media access control (MAC) control unit (CE).

5 . The method of claim 3 , wherein the first indication information and the transmission resource set are carried in a same sidelink channel.

6 . The method of claim 2 , wherein the starting location of the time domain and the ending location of the time domain are determined based on third indication information of the second terminal.

7 . The method of claim 6 , wherein the third indication information comprises time domain location indication information, wherein the time domain location indication information comprises the starting location of the time domain and the ending location of the time domain.

8 . The method of claim 6 , wherein the third indication information comprises indication information of a resource selection window, wherein the indication information of the resource selection window comprises:
a starting location of the resource selection window; an ending location of the resource selection window, wherein the starting location of the time domain is determined according to the starting location of the resource selection window, and the ending location of the time domain is determined according to the ending location of the resource selection window.

9 . The method of claim 6 , wherein the third indication information comprises information of a resource reservation period.

10 . A first terminal, comprising:
a transceiver, configured to send a transmission resource set to a second terminal, wherein a transmission resource included in the transmission resource set belongs to transmission resources in a first time-frequency range; wherein the first time-frequency range comprises a starting location of a frequency domain and an ending location of a frequency domain; wherein the starting location of the frequency domain and the ending location of the frequency domain are determined based on resource pool configuration information, wherein the resource pool configuration information comprises: an index of an initial sub-channel, a size of a sub-channel and a quantity of sub-channels of a resource pool.

11 . The first terminal of claim 10 , wherein the first time-frequency range comprises a starting location of a time domain and an ending location of a time domain.

12 . The first terminal of claim 11 , wherein the starting location of the time domain and the ending location of the time domain are determined based on first indication information sent by the first terminal.

13 . The first terminal of claim 12 , wherein the first indication information is carried in sidelink control information (SCI), or media access control (MAC) control unit (CE).

14 . The first terminal of claim 12 , wherein the first indication information and the transmission resource set are carried in a same sidelink channel.

15 . The first terminal of claim 11 , wherein the starting location of the time domain and the ending location of the time domain are determined based on third indication information of the second terminal.

16 . The first terminal of claim 15 , wherein the third indication information comprises time domain location indication information, and the time domain location indication information comprises the starting location of the time domain and the ending location of the time domain.

17 . The first terminal of claim 15 , wherein the third indication information comprise indication information of a resource selection window, and the indication information of the resource selection window comprises:
a starting location of the resource selection window; an ending location of the resource selection window, wherein the starting location of the time domain is determined according to the starting location of the resource selection window, and the ending location of the time domain is determined according to the ending location of the resource selection window.

18 . The first terminal of claim 15 , wherein the third indication information comprises information of a resource reservation period.
