    Abstract: A method is disclosed for performing timing advance command (TAC) updates, comprising: configuring an appropriate block error rate (BLER); forwarding a timing advance command (TAC) for a radio network temporary identifier (RNTI) x to a user equipment (UE), the TAC not equal to 31; tracking a time of receipt of a first downlink shared channel (DLSCH) protocol data unit (PDU) with redundancy version (RV) 0 at the user equipment (UE); adding k slots; and continuing tracking timing advance (TA) samples of the radio network temporary identifier (RNTI) x, where k may be based on the subcarrier spacing.

    Abstract: In one embodiment, a method includes transmitting a plurality of beamformed reference signals using a corresponding plurality of beamforming precoders; receiving from each of the plurality of UEs a signal quality metric for at least a subset of the plurality of beamformed reference signals; determining a beam-specific cross-correlation for pairs of the plurality of UEs using the signal quality metrics; determining one or more scheduling groups of UEs from the plurality of UEs based on the beam-specific cross-correlation for pairs of the plurality of UEs; and allocating a set of time-frequency resource elements to two or more UEs selected from one of the determined scheduling groups.
