  • Publication number: 20240155609
    Abstract: Aspects are provided for repeating a configuration for a transmission after contention resolution in an early contention resolution. An apparatus may be configured to obtain a configuration indicating a number of repetitions for a PUCCH transmission for a PDSCH prior to activation of a dedicated PUCCH resource configuration. The PUCCH transmission may include a HARQ feedback message after receiving a contention resolution message carried in a prior PDSCH in a random access procedure. The apparatus may also be configured to transmit the HARQ feedback message for the PDSCH on a PUCCH according to the number of repetitions. The apparatus may further be configured to transmit a subsequent HARQ feedback message for the PDSCH on the PUCCH according to the number of repetitions for the HARQ feedback message for the PDSCH on the PUCCH. This allows coverage techniques to be applied to certain transmissions in order to improve coverage and reliability.

  • Patent number: 11968013
    Abstract: Methods, systems, and devices for wireless communication are described. In aspects of the present disclosure, a user equipment (UE) may report metrics (e.g., received signal power, beam identifier) about synchronization signal (SS) beams using the same (e.g., or a similar) framework that is used for channel state information reference signal (CSI-RS) reporting. Because SSs are intended to be broadcast across a wide coverage area in a beamformed manner, the SSs represent a promising complement to existing beam management techniques. Accordingly, beam management may be achieved at least in part based on reporting one or more metrics of beamformed SSs through a channel feedback framework.
