1. An apparatus of a reduced capability (RedCap) user equipment (UE) comprising:
memory to store capability information for the RedCap UE that includes one or more of:
an indication of a number of receiver (Rx) branches supported by the RedCap UE for downlink (DL) reception, and an indication of a number of transmitter (Tx) branches supported by the RedCap UE for uplink (UL) transmission; and
processing circuitry, coupled with the memory, to:
retrieve the capability information from the memory;
encode a message for transmission to a next-generation NodeB (gNB) that includes the capability information;
support a maximum of one active transmission configuration indicator (TCI) state for physical downlink control channel (PDCCH) reception; and
receive a PDCCH transmission scheduling a physical downlink shared channel (PDSCH) transmission, wherein a demodulation reference signal (DMRS) associated with the PDSCH transmission has a common TCI state as a DMRS associated with the PDCCH transmission.
