Abstract: An apparatus is configured for a user equipment (UE) device. The apparatus comprises baseband circuitry and/or application circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to generate a physical random access channel (PRACH) within a slot at a medium access control (MAC) layer, generate a scheduling request (SR) within the slot at the MAC layer, determine a PRACH prioritization and an SR prioritization at a physical layer according to a prioritization rule; and provide the PRACH and the SR to the RF interface for transmission according to the prioritization rule.

Abstract: Technology for a user equipment (UE) operable to assist a Next Generation NodeB (gNB) for beamforming is disclosed. The UE can determine a covariance matrix for a channel between the UE and the gNB. The UE can quantize the covariance matrix to obtain a quantized covariance matrix. The quantized covariance matrix can include M best diagonal entries that are selected from the covariance matrix, wherein M is an integer. The UE can encode the quantized covariance matrix as feedback for transmission to the gNB.
