Embodiment 1

[0320] In this embodiment, the available resources are specific locations of time-frequency resources, and the first terminal sends indication information to a second terminal;

[0321] The indication information includes information about a specific location of a time-frequency resource of a second terminal; and the indication information includes an identifier of the second terminal.

[0322] Optionally, the information about the specific location of the time-frequency resource includes at least one of the following information:

[0323] 1. The number of time-frequency resources;

[0324] 2. The carrier index where the time-frequency resource is located;

[0325] 3. The index of the resource pool where the time-frequency resource is located;

[0326] 4. Partial bandwidth BWP index where the time-frequency resource is located;

[0327] 5. The parameter set of the time-frequency resource;

[0328] Wherein, the parameter set (numerology) of the time-frequency resource may s...

Embodiment 2

[0345] In this embodiment, the available resources are specific locations of time-frequency resources, and the first terminal sends indication information to multiple second terminals;

[0346] The indication information includes information about the specific location of the time-frequency resource of each second terminal; and the indication information includes the identity of the second terminal, and the indication information also includes each second terminal and the specific location of the time-frequency resource Correspondence of related information.

[0347] For example, the first terminal configures available resources for four second terminals, and the four second terminals are UE1 identified as "1", UE2 identified as "2", UE3 identified as "3", and UE3 identified as "4". ”; the indication information includes the identities of the four second terminals, and the relevant information about the specific location of the time-frequency resource corresponding to each sec...

Embodiment 3

[0350] In this embodiment, the available resource is a resource pool, and the first terminal sends indication information to a second terminal;

[0351] The indication information includes information about a resource pool of a second terminal; and the indication information includes an identifier of the second terminal.

[0352] In this embodiment, the indication information includes at least one of the following information:

[0353] 1. The carrier index where the resource pool is located;

[0354] 2. The index of the resource pool;

[0355] 3. The parameter set corresponding to the resource pool;

[0356] Wherein, the parameter set corresponding to the resource pool may specifically be subcarrier spacing and / or time slot length.

[0357] 4. Time-domain resource location indication of the resource pool, and / or frequency-domain resource location indication;

[0358] Wherein, the time-domain resource location indication of the resource pool and / or the expression manner of ...

Abstract

The present invention relates to the field of wireless communication technology, in particular to a resource indication method and a terminal, which are used to solve the problem that the way of UE autonomous resource selection cannot effectively avoid the influence of half-duplex, which will cause the inability to successfully receive messages sent by other members in the group, reliability drop problem. In the embodiment of the present invention, the first terminal determines the available resources configured for at least one second terminal; the first terminal sends indication information including information about the available resources of each second terminal to at least one second terminal, so that the second terminal According to the indication information, the transmission resources used when performing direct link communication with other terminals are determined. Since the first terminal in the embodiment of the present invention sends the indication information of available resource-related information to the second terminal, the second terminal no longer uses the method of autonomously selecting resources to determine the transmission resources used in direct link communication, effectively avoiding the impact of half-duplex. Improves communication reliability over direct links.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource indication method and a terminal. Background technique [0002] 3GPP Release14 and Release 15's LTE-V2X (Long Term Evolution-Vehicle to Everything; LTE: Long Term Evolution, Long Term Evolution; V2X: Vehicle to Everything) direct link communication supports direct link transmission mode 3 and direct link Send mode 4. In direct link transmission mode 3, the base station allocates resources for terminal scheduling, and in direct link transmission mode 4, UE (User Equipment, user equipment) independently selects resources. The LTE-V2X direct link communication of 3GPP Release14 and Release 15 only supports broadcast communication. [0003] The direct link transmission mode 4 of 3GPP Release14 supports the resource selection mechanism of Sensing+SPS (sensing+SPS (semi-persistent schedule, semi-persistent scheduling)), and the specific scheme is as ...
