Beam management procedures in radio systems
Abstract:
A wireless device receives, from a base station, one or more messages comprising configuration parameters indicating a sounding reference signal (SRS) resource set. A downlink control information is received. The downlink control information comprising an SRS resource indicator (SRI) and an uplink transmission configuration indicator (UL-TCI). The SRI indicates one or more SRS resources of the SRS resource set. In response to the UL-TCI being equal to a predefined value, a determination is made of an uplink spatial domain transmission filter based on the one or more SRS resources of the SRS resource set. A transport block with the uplink spatial domain transmission filter is transmitted via a physical uplink shared channel.
