USER EQUIPMENT AND BASE STATIONS THAT ACHIEVE UPLINK MULTIPLEXING

Title:

USER EQUIPMENT AND BASE STATIONS THAT ACHIEVE UPLINK MULTIPLEXING

Document Type and Number:

WIPO Patent Application WO/2020/262202

Kind Code:

A1

Abstract:

A user equipment (UE) is described. The UE includes receiving circuitry configured to monitor a physical downlink control channel (PDCCH) conveying a pre-emption indication that indicates pre-emption of a physical uplink shared channel (PUSCH) transmission. The receiving circuitry is also configured to receive radio resource control (RRC) signaling that comprises a configuration for a configured grant and a configuration for grant-based PUSCH. The UE also includes a higher layer processor configured to determine whether to follow the configuration for the configured grant or the configuration for grant-based PUSCH for a scheduled retransmission of a TB previously transmitted on a PUSCH with a configured grant. The UE further includes transmitting circuitry configured to transmit or skip the PUSCH transmission based on the pre-emption indication.
