1. 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.
