Abstract

Apparatus, systems, and methods to implement enhanced sounding reference signaling for uplink (UL) beam tracking in communication systems are described. In one example, an apparatus of an evolved Node B (eNB) comprising processing circuit to broadcast system information about one or more sets of uplink transmit time intervals and bandwidths available for a sounding reference signal (SRS) transmission from a first user equipment (UE), configure one or more UE-specific SRS processes for the first UE for uplink beam tracking, and configure one or more millimeter wave access points (mmW APs) to transmit a mmW signal to the first UE and receive a mmW signal from the first UE. Other examples are also disclosed and claimed.
