In a wireless communications system, a first UE may determine, for a set of symbols for sidelink communications between the first UE and a second UE, a first resource configuration including a single first TTI and a second resource configuration including two or more second TTIs. The first TTI and the second TTIs may span the set of symbols, and the two or more second TTIs may be shorter in length than the single first TTI. The first UE may select, from the first resource configuration and the second resource configuration, a sidelink channel resource configuration for a data transmission to the second UE. Then, the first UE may transmit the data transmission to the second UE according to the selected sidelink channel resource configuration.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a first configuration for a physical uplink control channel (PUCCH) resource set, the first configuration associated with a first configured number of symbols for a PUCCH. The UE may receive, from the base station, an indication of a number of symbols to be used for transmitting the PUCCH, the indicated number of symbols being different from the first configured number of symbols. The UE may transmit the PUCCH using the indicated number of symbols. Numerous other aspects are provided.
