1 . An apparatus for wireless communication at a user equipment (UE), comprising: one or more memories; and one or more processors coupled with the one or more memories and configured to cause the UE to: receive a first signal that indicates a communication resource pool comprising one or more contention-based communication resources for sidelink communications; receive a second signal that indicates a quantity of repetitions associated with the communication resource pool; and communicate, via a contention-based communication resource from the communication resource pool, one or more repetitions of a sidelink communication in a number of consecutive time periods based at least in part on the quantity of repetitions, the one or more repetitions of the sidelink communication unassociated with control information used for scheduling.
2 . The apparatus of claim 1 , wherein the one or more processors are configured to cause the UE to: select, based at least in part on a configuration for transmission priority or for detection of transmissions that overlap, the contention-based communication resource from the communication resource pool to communicate the one or more repetitions of the sidelink communication.
3 . The apparatus of claim 1 , wherein, to communicate the one or more repetitions of the sidelink communication, the one or more processors are configured to cause the UE to: communicate consecutive repetitions of the sidelink communication via at least partially different frequency ranges.
4 . The apparatus of claim 1 , wherein the one or more processors are configured to cause the UE to: identify a redundancy version identifier for each of the one or more repetitions of the sidelink communication based at least in part on a configured pattern of redundancy version identifiers.
5 . The apparatus of claim 1 , wherein the one or more processors are configured to cause the UE to: receive a third signal from a broadcast UE, the third signal indicating the communication resource pool, the quantity of repetitions, or both.
6 . The apparatus of claim 1 , wherein the one or more processors are configured to cause the UE to: receive a third signal from a base station, the third signal indicating the communication resource pool, the quantity of repetitions, or both.
7 . The apparatus of claim 1 , wherein the one or more processors are configured to cause the UE to: perform a combining process based at least in part on the one or more repetitions of the sidelink communication.
8 . The apparatus of claim 1 , the quantity of repetitions associated with feedback.
9 . The apparatus of claim 1 , the quantity of repetitions unassociated with feedback.
10 . A method for wireless communication at a user equipment (UE), comprising: receiving a first signal that indicates a communication resource pool comprising one or more contention-based communication resources for sidelink communications; receiving a second signal that indicates a quantity of repetitions associated with the communication resource pool; and communicating, via a contention-based communication resource from the communication resource pool, one or more repetitions of a sidelink communication in a number of consecutive time periods based at least in part on the quantity of repetitions, the one or more repetitions of the sidelink communication unassociated with control information used for scheduling.
11 . The method of claim 10 , further comprising: selecting, based at least in part on a configuration for transmission priority or for detection of transmissions that overlap, the contention-based communication resource from the communication resource pool to communicate the one or more repetitions of the sidelink communication.
12 . The method of claim 10 , the communicating the one or more repetitions of the sidelink communication comprising: communicating consecutive repetitions of the sidelink communication via at least partially different frequency ranges.
13 . The method of claim 10 , further comprising: identifying a redundancy version identifier for each of the one or more repetitions of the sidelink communication based at least in part on a configured pattern of redundancy version identifiers.
14 . The method of claim 10 , further comprising: receiving a third signal from a broadcast UE, the third signal indicating the communication resource pool, the quantity of repetitions, or both.
15 . The method of claim 10 , further comprising: receiving a third signal from a base station, the third signal indicating the communication resource pool, the quantity of repetitions, or both.
16 . The method of claim 10 , further comprising: performing a combining process based at least in part on the one or more repetitions of the sidelink communication.
17 . The method of claim 10 , the quantity of repetitions associated with feedback.
18 . The method of claim 10 , the quantity of repetitions unassociated with feedback.
19 . A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable by one or more processors to cause the UE to: receive a first signal that indicates a communication resource pool comprising one or more contention-based communication resources for sidelink communications; receive a second signal that indicates a quantity of repetitions associated with the communication resource pool; and communicate, via a contention-based communication resource from the communication resource pool, one or more repetitions of a sidelink communication in a number of consecutive time periods based at least in part on the quantity of repetitions, the one or more repetitions of the sidelink communication unassociated with control information used for scheduling.
20 . The non-transitory computer-readable medium of claim 19 , wherein the instructions are executable by the one or more processors to cause the UE to: select, based at least in part on a configuration for transmission priority or for detection of transmissions that overlap, the contention-based communication resource from the communication resource pool to communicate the one or more repetitions of the sidelink communication.
