Beam Management and Beam Indication in Radio Systems
Abstract:
A wireless device receives configuration parameters, of a physical uplink control channel (PUCCH), indicating a timing gap threshold between a physical downlink shared channel (PDSCH) and the PUCCH. The wireless device receives one or more messages indicating a downlink transmission configuration indication (TCI) and an uplink TCI. The wireless device transmits uplink control information via the PUCCH using a spatial domain transmission filter, wherein the spatial domain transmission filter is based on one of the downlink TCI or the uplink TCI in response to a comparison between the timing gap threshold and a timing gap between a PDSCH resource and a PUCCH resource.
