Abstract: An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for a 4-step random access procedure with a gNB in a 5G-NR network, the processing circuitry is to encode a first message for transmission to the gNB using a PRACH, the first message including a random access preamble. A second message received from the gNB in response to the first message is decoded. The second message includes a MAC RAR with an uplink (UL) grant and an indication of an LBT procedure type or a channel access and CP extension. An LBT procedure based on the LBT procedure type or the channel access and CP extension provided in the indication is performed. Data is encoded for transmission to the gNB based on successful completion of the LBT procedure, the transmission using a PUSCH, and a UL resource indicated by the UL grant.

Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.
