Abstract: Various embodiments herein provide techniques for indication of a starting frequency of a control resource set (CORESET). In embodiments, two modes for determining the starting frequency are provided. An access node (e.g., next generation Node B (gNB)) may send an indication to a user equipment (UE) to indicate which mode to use (e.g., in a payload of a physical broadcast channel (PBCH)). Other embodiments may be described and claimed.

Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) unlicensed band (NR-U) communications, the processing circuitry is to decode downlink control information (DCI) received via a physical downlink control channel (PDCCH). The DCI provides allocation of uplink frequency resources of a transmission bandwidth. The allocation is a block interleaved frequency division multiple access (B-IFDMA) allocation including a plurality of interleaved physical resource blocks (PRBs) forming M number of interlaces within the transmission bandwidth, and N number of PRBs within each interlace of the M number of interlaces, with N and M being integers greater than or equal to 1. Data is encoded for transmission to a base station via a physical uplink shared channel (PUSCH) using the B-IFDMA allocation of uplink frequency resources.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for enhanced demodulation reference signal (DMRS) for uplink transmissions with up to eight layers (e.g., an uplink single user (SU)-multiple input, multiple output (MIMO) transmission). Additionally, embodiments relate to antenna port indication for DMRS transmission. Other embodiments may be described and claimed.

Abstract: Various embodiments herein provide techniques for minimum mean-square error interference rejection combining (MMSE-IRC) processing of a received signal, distributed between a baseband unit (BBU) and a remote radio unit (RRU). The RRU may perform uplink receive beamforming (e.g., using maximum ratio combining (MRC)) based on multiple channel measurements (e.g., a set of multiple sounding reference signal (SRS) channel measurements) obtained on respective measurement signals transmitted by a user equipment (UE). The RRU may send the processed signal to the BBU for further processing. The BBU may perform MMSE-IRC based on the processed signal received from the RRU, e.g., using demodulation reference signals (DM-RSs). Other embodiments may be described and claimed.
