A method of resource reservation, the method comprising:

a first terminal sends a first channel, wherein the first channel is used for determining information of resources selected by the first terminal.

The method of claim 1, wherein the first channel is a Physical Sidelink Control Channel (PSCCH) including information of the resource selected by the first terminal.

The method of claim 2, wherein the PSCCH carries information of the resources selected by the first terminal through a first sidelink control information SCI.

The method of claim 1, wherein the first channel is a Physical Sidelink Shared Channel (PSSCH), and the PSSCH includes information about resources selected by the first terminal.

The method of claim 4, wherein the PSSCH carries information of the resource selected by the first terminal through a Media Access Control (MAC) Control Element (CE).

The method of claim 1, wherein the first channel is a PSCCH, the PSCCH includes first indication information, and the first indication information is used to indicate that a PSCCH corresponding to the PSCCH includes information about a resource selected by the first terminal.

The method of claim 6, wherein the PSCCH carries the first indication information with a second SCI.

The method of any of claims 1 to 7, wherein the first terminal transmitting a first channel comprises:

and the first terminal sends the first channel in the latest transmission period before a target time, wherein the target time is the time when the service data arrives or the time when a higher layer generates the service data.

The method of any of claims 1 to 8, wherein the method further comprises:

the first terminal receives a second channel sent by a second terminal, and determines whether the first terminal can use the resource selected in the first selection window or not based on the second channel;

if the resource selected by the first terminal and the resource selected by the second terminal have an overlapping part, when the service priority of the first terminal is higher than the service priority of the second terminal, the first terminal can transmit data or signaling by using the resource selected by the first terminal; and when the service priority of the first terminal is lower than that of the second terminal, the first terminal cannot transmit data or signaling by using the resource selected by the first terminal.

The method of claim 9, wherein the method further comprises:

if the service priority of the first terminal is the same as the service priority of the second terminal, when the time of sending the first channel of the first terminal is earlier than the time of sending the second channel of the second terminal, the first terminal can use the resource selected by the first terminal to transmit data or signaling; and when the time of the first terminal for sending the first channel is later than the time of the second terminal for sending the second channel, the first terminal cannot use the resource selected by the first terminal to transmit data or signaling.

The method according to claim 9 or 10, wherein when the first terminal cannot transmit data or signaling using the resource selected by the first terminal, the first terminal performs resource listening again and performs resource selection again.

An apparatus for resource reservation, the apparatus comprising:

a sending unit, configured to send a first channel, where the first channel is used to determine information of a resource selected by the first terminal.

The apparatus of claim 12, wherein the first channel is a PSCCH that includes information about resources selected by the first terminal.

The apparatus of claim 13, wherein the PSCCH carries information of the resource selected by the first terminal through a first SCI.

The apparatus of claim 12, wherein the first channel is a PSSCH including information of resources selected by the first terminal.

The apparatus of claim 15, wherein the psch carries information of the resource selected by the first terminal through a MAC CE.

The apparatus of claim 12, wherein the first channel is a PSCCH, the PSCCH includes first indication information, and the first indication information is used to indicate that a PSCCH corresponding to the PSCCH includes information about a resource selected by the first terminal.

The apparatus of claim 17, wherein the PSCCH carries the first indication information with a second SCI.

The apparatus according to any of claims 12 to 18, wherein the transmitting unit is configured to transmit the first channel in a last transmission cycle before a target time, where the target time is a time when traffic data arrives or a time when a higher layer generates traffic data.

The apparatus of any one of claims 12 to 19, wherein the apparatus further comprises:

a receiving unit, configured to receive a second channel sent by a second terminal, and determine whether the first terminal can use the resource selected in the first selection window based on the second channel;

a conflict processing unit, configured to, if the resource selected by the first terminal and the resource selected by the second terminal have an overlapping portion, enable the first terminal to transmit data or a signaling using the resource selected by the first terminal when the service priority of the first terminal is higher than the service priority of the second terminal; and when the service priority of the first terminal is lower than that of the second terminal, the first terminal cannot transmit data or signaling by using the resource selected by the first terminal.

The apparatus of claim 20, wherein the collision processing unit is further configured to, if the traffic priority of the first terminal is the same as the traffic priority of the second terminal, enable the first terminal to transmit data or signaling using the resource selected by the first terminal when the time of the first terminal transmitting the first channel is earlier than the time of the second terminal transmitting the second channel; and when the time of the first terminal for sending the first channel is later than the time of the second terminal for sending the second channel, the first terminal cannot use the resource selected by the first terminal to transmit data or signaling.

The apparatus according to claim 20 or 21, wherein when the first terminal is unable to transmit data or signaling using the resource selected by the first terminal, the resource listening unit performs resource listening again, and the resource selecting unit performs resource selection again.

A computer storage medium having stored thereon computer-executable instructions which, when executed by a processor, carry out the method steps of any of claims 1 to 11.
