Uplink beam management in wireless communication system
A wireless device receives configuration parameters comprising first parameters of downlink RSs and second parameter indicating that a default beam is used for uplink transmission. A DCI indicating a first uplink transmission via a PUSCH resource is received. A spatial relation information, for the first uplink transmission, is determined to be associated with one of the downlink reference signals in response to the second parameter indicating that the default beam is used. A transport block is transmitted via the PUSCH resource according to the spatial relation information.
