Abstract

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform PUCCH repetition based on signaling from at least one base station. The UE may connect to at least one base station. The UE may receive signaling from the at least one base station configuring physical uplink control channel (PUCCH) transmission. The signaling may indicate a plurality of PUCCH resources for PUCCH repetition. The signaling may indicate a plurality of beams for PUCCH repetition. Based on the signaling from the at least one base station, the UE may transmit the PUCCH a plurality of times using the plurality of PUCCH resources and the plurality of beams.

Claims17

Dependent claims

A user equipment device (UE), comprising:

wireless communication circuitry;
and
one or more processors coupled to the wireless communication circuitry, wherein the one or more processors are configured to cause the UE to:
connect to at least one base station;
receive a configuration from the at least one base station configuring physical uplink control channel (PUCCH) resource, wherein the configuration indicates PUCCH transmission repetitions, and wherein a plurality of spatial relations are configured for the PUCCH transmissions repetitions;
receive a media access control (MAC) control element (CE) activating more than one spatial relation of the plurality of spatial relations for the PUCCH resource;
and
transmit the PUCCH transmission repetitions on the PUCCH resource using the plurality of spatial relations, wherein a respective PUCCH repetition is transmitted using one of the plurality of spatial relations and the repetitions are space division multiplexed within a slot.
