Abstract: Enhanced beam management for a wireless communication system is provided. In one example, a method comprises: receiving, from a mobile device, a message indicating first beam information for a selected first beam of beams associated with the base station device, wherein the message is a first received message of a random access channel procedure; and receiving, from the mobile device, message indicating second beam information for a selected second beam of the beams associated with the base station device, wherein the selected second beam is an alternative to the selected first beam for transmission of downlink data to the mobile device from the base station device, and wherein the second beam is indicated in the first message of a two-step random access channel procedure. Methods of signaling the second beam and/or transmission diversity approaches employing the first beam and/or the second beam are described.

Abstract: An example method may include a processing system of a device having a processor capturing, at a first position comprising a first location and a first spatial orientation of the device, a first measurement of a performance indicator based upon at least a first wireless signal from a base station of a beamformed wireless communication network and capturing, at a second position comprising a second location and a second spatial orientation of the device, a second measurement of the performance indicator based upon at least a second wireless signal from the base station of the beamformed wireless communication network. The method may include the processing system selecting a position for a deployment of the device based upon the first measurement of the performance indicator and the second measurement of the performance indicator and providing at least one instruction for the deployment of the device at the position that is selected.
