    摘要: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of channel state processes scheduled to be performed. The UE may receive a channel state feedback request corresponding to another set of channel state processes. The combination of the set of channel state processes and the other set of channel state processes may be greater than an amount that the UE may process at a given time. The UE may determine a priority for the channel state processes either on an individual or group basis. The UE may determine channel state process (es) to drop based on the determined priorities, and may perform the remaining channel state processes. The UE may generate and transmit a channel state feedback report message based on the performed channel state processes.

    摘要: 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.

    摘要: Aspects relate to mechanisms for improved uplink and sidelink coverages. A first network entity determines one or more channel state feedback (CSF) parameters of one or more beams associated with the first network entity, selects one or more beam coefficients based on the one or more CSF parameters, and transmits the one or more beam coefficients to at least a second network entity. The second network entity selects one or more beams for beaming forming based on the one or more beam coefficients, determines one or more CSF parameters of the one or more beams associated with the second network entity, and transmits the one or more CSF parameters of the one or more beams associated with the second network entity to the first network entity. The first network entity selects one or more new beam coefficients based on the one or more CSF parameters from the second network entity.
