  • METHODS FOR UPLINK CONTROL CHANNEL CARRIER SWITCHING
    Publication number: 20240196390
    Abstract: PUCCH carrier switching at a UE may include decoding an RRC configuration including a time-domain pattern indicating a reference cell and a target PUCCH cell for one or more PUCCH transmissions at a given point in time. The reference cell may include a reference cell slot numerology and the target PUCCH cell may include a target PUCCH cell slot numerology. A slot for PUCCH transmissions may be determined based on the reference cell slot numerology. The determined slot may be used for transmission of at least one of an SR, a CSI, and a HARQ-ACK. The determined slot of the reference cell may be mapped to a corresponding slot of the target PUCCH cell. A PUCCH resource may be determined for performing a PUCCH transmission using the corresponding slot of the target PUCCH cell. The PUCCH resource determination may be based on a PUCCH configuration of the target PUCCH cell.

    Publication number: 20240195572
    Abstract: Systems and methods provide for physical downlink control channel (PDCCH) monitoring adaptation. A user equipment (UE) may monitor a default search space set group (SSSG) for downlink control information (DCI) from a base station in the PDCCH. In response to a first DCI trigger, the UE switches from monitoring the default SSSG to monitoring a first non-default SSSG associated with a first timer. In response to a second DCI trigger, the UE switches from monitoring the first non-default SSSG to monitoring a second non-default SSSG associated with a second timer. The first non-default SSSG may be a non-empty SSSG including a search space set with at least one associated search space. The second non-default SSSG may be an empty SSSG with no associated search space to emulate PDCCH skipping.

Each of the retransmission may include a corresponding transmission number. As an alternative, each of the retransmissions may be at least partially scrambled using a corresponding Radio Network Temporary Identifier (RNTI). As another alternative, a window for monitoring and RNTI calculation may be extended to include the one or more retransmissions. The successive retransmissions may include the same set of UE-specific payloads, or, a decreasing set of payloads over time as UE devices acknowledge successful receipt of their respective payloads.
