Communication using semi-persistent scheduling and sensing
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first transmission, wherein the first transmission includes information identifying a window, and wherein the UE is to transmit at least part of a second transmission in the window; and transmit at least part of the second transmission in the window. Numerous other aspects are provided.

one or more memories; and
one or more processors coupled to the one or more memories, the one or more processors configured to cause the UE to:
select one or more resources, of a window for a second transmission, that do not overlap one or more preemptive resources based at least in part on a priority level of another UE associated with a third transmission in the window;
transmit a first transmission including information that identifies the one or more selected resources that do not overlap the one or more preemptive resources; and
transmit at least part of the second transmission using the one or more selected resources that do not overlap the one or more preemptive resources.
2. The UE of claim 1 , wherein the one or more selected resources include one or more of:
one or more time resources, or
one or more frequency resources.
3. The UE of claim 1 , wherein the one or more processors, to cause the UE to transmit the first transmission, are configured to cause the UE to:
transmit the first transmission in a control channel.
4. The UE of claim 1 , wherein the first transmission is a UE-to-UE communication.
5. The UE of claim 1 , wherein the information comprises a reservation for the second transmission.
6. The UE of claim 1 , wherein the one or more processors, to cause the UE to select the one or more resources, cause the UE to:
select the one or more resources based at least in part on a past window or a past transmission by the other UE.
7. The UE of claim 1 , wherein the one or more selected resources are not occupied by the third transmission.
8. The UE of claim 1 , wherein the one or more processors, to cause the UE to select the one or more resources, cause the UE to:
select the one or more resources based at least in part on a proximity of the other UE.
9. The UE of claim 1 , wherein the second transmission comprises one of:
a retransmission of the first transmission,
a repetition of the first transmission, or
a new transmission different from the first transmission.
10. A method of wireless communication performed by a user equipment (UE), comprising:
selecting one or more resources, of a window for a second transmission, that do not overlap one or more preemptive resources based at least in part on a priority level of another UE performing a third transmission in the window;
transmitting a first transmission including information identifying the one or more selected resources that do not overlap the one or more preemptive resources; and
transmitting at least part of the second transmission using the one or more selected resources that do not overlap the one or more preemptive resources.
11. The method of claim 10 , wherein the one or more selected resources include one or more of:
one or more time resources, or
one or more frequency resources.
12. The method of claim 10 , wherein the first transmission is transmitted in a control channel.
13. The method of claim 10 , wherein the first transmission is a UE-to-UE communication.
14. The method of claim 10 , wherein the information comprises a reservation for the second transmission.
15. The method of claim 10 , wherein the one or more resources are selected based at least in part on a past window or a past transmission by the other UE.
16. The method of claim 10 , wherein the one or more selected resources are not occupied by the third transmission.
17. The method of claim 10 , wherein the second transmission comprises one of:
a retransmission of the first transmission,
a repetition of the first transmission, or
a new transmission different from the first transmission.
18. The method of claim 10 , wherein the one or more resources are selected based at least in part on a proximity of the other UE.
19. A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
select one or more resources, of a window for a second transmission, that do not overlap one or more preemptive resources based at least in part on a priority level of another UE associated with a third transmission in the window;
transmit a first transmission including information that identifies the one or more selected resources that do not overlap the one or more preemptive resources; and
transmit at least part of the second transmission using the one or more selected resources that do not overlap the one or more preemptive resources.
20. The non-transitory computer-readable medium of claim 19 , wherein the one or more selected resources include one or more of:
one or more time resources, or
one or more frequency resources.
21. The non-transitory computer-readable medium of claim 19 , wherein the first transmission is transmitted in a control channel.
22. The non-transitory computer-readable medium of claim 19 , wherein the first transmission is a UE-to-UE communication.
23. The non-transitory computer-readable medium of claim 19 , wherein the information comprises a reservation for the second transmission.
24. The non-transitory computer-readable medium of claim 19 , wherein the one or more instructions, that cause the UE to select the one or more resources, cause the UE to select the one or more resources based at least in part on a past window or a past transmission by the other UE.
25. The non-transitory computer-readable medium of claim 19 , wherein the second transmission comprises one of:
a retransmission of the first transmission,
a repetition of the first transmission, or
a new transmission different from the first transmission.
26. The non-transitory computer-readable medium of claim 19 , wherein the one or more instructions, that cause the UE to select the one or more resources, cause the UE to select the one or more resources based at least in part on a proximity of the other UE.
27. An apparatus for wireless communication, comprising:
means for selecting one or more resources, of a window for a second transmission, that do not overlap one or more preemptive resources based at least in part on a priority level of another UE performing a third transmission in the window;
means for transmitting a first transmission including information identifying the one or more selected resources that do not overlap the one or more preemptive resources; and
means for transmitting at least part of the second transmission using the one or more selected resources that do not overlap the one or more preemptive resources.
