Abstract

A wireless device may initialize a candidate resource set for a sidelink transmission. The wireless device may exclude a first resource from the candidate resource set based on: the first resource being offset from a second resource by one or more reservation periods, and the second resource not being monitored in a sensing window. The wireless device may receive sidelink control information (SCI) indicating a resource reservation of the first resource. The wireless device may transmit, via the first resource, the sidelink transmission.

First claim

What is claimed is:

1 . A method comprising:
initializing, by a wireless device, a candidate resource set for a sidelink transmission; excluding a first resource from the candidate resource set based on:
the first resource being offset from a second resource by one or more reservation periods; and
the second resource not being monitored in a sensing window;
receiving a sidelink control information (SCI) indicating a resource reservation of the first resource; and transmitting, via the first resource, the sidelink transmission.

2 . The method of claim 1 , wherein the candidate resource set comprises candidate resources in a selection window of a resource selection procedure due to sidelink pre-emption.

3 . The method of claim 2 , wherein the sensing window is of the resource selection procedure.

4 . The method of claim 2 , further comprising receiving one or more configuration parameters indicating:
the sensing window of the resource selection procedure; the selection window of the resource selection procedure; and the one or more reservation periods for resource reservation.

5 . The method of claim 1 , wherein the transmitting further comprising transmitting the sidelink transmission based on a reference signal received power (RSRP) of the first resource being lower than a RSRP threshold.

6 . The method of claim 5 , wherein the RSRP threshold is incremented to a final value.

7 . The method of claim 1 , further comprising adding the first resource back to the candidate resource set based on the receiving of the SCI.

8 . The method of claim 1 , wherein the SCI indicates a first priority level.

9 . The method of claim 8 , wherein the transmitting further comprising transmitting the sidelink transmission based on the first priority level being lower than a second priority level of the sidelink transmission.

10 . The method of claim 9 , wherein a first priority value, indicating the first priority level, is greater than a second priority value, indicating the second priority level.

11 . A wireless device comprising:
one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
initialize, by a wireless device, a candidate resource set for a sidelink transmission;
exclude a first resource from the candidate resource set based on:
the first resource being offset from a second resource by one or more reservation periods; and
the second resource not being monitored in a sensing window;

receive a sidelink control information (SCI) indicating a resource reservation of the first resource; and
transmit, via the first resource, the sidelink transmission.

12 . The wireless device of claim 11 , wherein the candidate resource set comprises candidate resources in a selection window of a resource selection procedure due to sidelink pre-emption.

13 . The wireless device of claim 12 , further comprising receiving one or more configuration parameters indicating:
the sensing window of the resource selection procedure; the selection window of the resource selection procedure; and the one or more reservation periods for resource reservation.

14 . The wireless device of claim 11 , wherein the transmitting further comprising transmitting the sidelink transmission based on a reference signal received power (RSRP) of the first resource being lower than a RSRP threshold.

15 . The wireless device of claim 14 , wherein the RSRP threshold is incremented to a final value.

16 . The wireless device of claim 11 , further comprising adding the first resource back to the candidate resource set based on the receiving of the SCI.

17 . The wireless device of claim 11 , wherein the SCI indicates a first priority level.

18 . The wireless device of claim 17 , wherein the transmitting further comprising transmitting the sidelink transmission based on the first priority level being lower than a second priority level of the sidelink transmission.

19 . The wireless device of claim 17 , wherein a first priority value, indicating the first priority level, is greater than a second priority value, indicating the second priority level.

20 . A system comprising:
a first wireless device comprising one or more first processors and first memory storing first instructions that, when executed by the one or more first processors, cause the first wireless device to:
initialize a candidate resource set;
exclude a first resource from the candidate resource set based on:
the first resource being offset from a second resource by one or more reservation periods; and
the second resource not being monitored in a sensing window;

receive a sidelink control information (SCI) indicating a resource reservation of the first resource; and
transmit, via the first resource, a sidelink transmission; and
a second wireless device comprising one or more second processors and second memory storing second instructions that, when executed by the one or more second processors, cause the second wireless device to:
receive, via the first resource, the sidelink transmission.
