Abstract
Methods and apparatus of performing spatial relation switching in new radio (NR) system is proposed. In one embodiment, a configured spatial relation of an uplink channel is Quasi-Co-Located (QCLed) to the source of a downlink reference signal (DL RS). In this QCLed relation, the active spatial relation switching shall differentiate known and unknown situation. In another embodiment, the configured spatial relation is QCLed to the root source of an uplink sounding reference signal (SRS). In this QCLed relation, the active spatial relation switching does not need to differentiate known and unknown situation. The proposed spatial relation switching shall apply for physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), and SRS transmission.
