    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) of a group of UEs may receive a groupcast retransmission from one or more UEs of the group. For example, a base station may transmit a groupcast transmission to the group of UEs. A first UE of the group of UEs may fail to receive the groupcast transmission and, in response, may transmit a feedback message via a sidelink feedback resource to a second UE of the group of UEs. The feedback message may include a negative acknowledgement (NACK) that indicates the failed reception of the groupcast transmission by the first UE, and the sidelink feedback resource may be indicated by the base station. The second UE may transmit a retransmission of the groupcast transmission to the first UE via a sidelink resource based on receiving the feedback message.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine two or more colliding uplink transmissions, wherein the two or more colliding uplink transmissions include first traffic and second traffic. The UE may select, from the two or more colliding uplink transmissions, one of the first traffic or the second traffic based at least in part on a first stage priority handling and a second stage priority handling, wherein the first traffic or the second traffic is selected based at least in part on one of three possible priority levels assigned to each of the two or more colliding uplink transmissions. The UE may transmit, to a network node, the one of the first traffic or the second traffic that is selected. Numerous other aspects are described.

    Abstract: Aspects relate to switching between different search space set groupings. A base station (BS) may send an indication to a user equipment (UE) to instruct the UE to switch from a first search space set grouping (SSSG) to a second SSSG. For example, the BS may send this indication after the BS transmits a first data burst to the UE. In some examples, the UE may then switch back to the first SSSG upon expiration of a timer. For example, the BS may configure the UE with a timer value (e.g., an absolute value, a relative value, or an indication thereof) that the UE may use to determine when to switch back to the first SSSG to receive a second data burst from the base station. In some examples, the UE may switch back to the first SSSG based on a discontinuous reception duration.
