Abstract

Flexibly configured containers consisting of resources within time-frequency blocks may be used to support multiple numerologies in new radio architectures. Uplink control may be defined in resources within a container, or in dedicated resources, by various nodes.

Sounding reference signal resources may be dynamically configured for each numerology. The sequence length may be adapted, as well as the time domain location of symbols. Time, frequency, and orthogonal resources may be allocated via a downlink control channel or a radio resource control.

Sounding reference signals may be pre-coded, and pre-coding weights may be based on a codebook or non-codebook approaches, e.g., via a radio resource control or a downlink RRC or DL control channel. Pre-coded sounding reference signals may be adapted to user equipment antenna configuration. Further, NR-SRS may be used as UL demodulation RS (DM-RS).
