Embodiment Construction

[0028] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to limit the scope of the present disclosure. Rather, the detailed description includes specific details in order to provide a thorough understanding of the inventive subject matter. It will be apparent to those skilled in the art that these specific details are not required in every instance, and in some instances, well-known structures and components are shown in block diagram form for clarity of presentation.

[0029]The detailed description relates to Logical Channel Prioritization (LCP) enhancements. Typically, a UE uses LCP to select a logical channel for uplink data. When operating in some Transceiver Point (TRP) modes, a UE may transmit data to different TRPs with spatial diversity (eg, different locations due to different antenna devices). The UE may send duplicate data to increase throughput and rel...

Abstract

Aspects of enhanced logical channel prioritization mapping processes and restrictions are disclosed. In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), a logical channel prioritization (LCP) restriction configuration for a logical channel, the LCP restriction configuration indicating a set of SRS configurations associated with the logical channel; receiving, by the UE, an uplink grant indicating an uplink grant instance and an SRS configuration for the uplink grant instance; and selecting, by the UE, a logical channel to use resources of the uplink grant instance based in part on the SRS configuration set and the SRS configuration for the uplink grant instance. Other aspects are also described.
