Abstract
In a radio access network, user equipment (UE) is to encode signaling for sector-sweep transmission to a base station via a plurality of directional beams in a millimeter-wave radio band over a random-access shared channel during at least one contention period, and determine a transmission power setting for the directional transmission. The transmission power setting is based on a targeted received signal characteristic to be achieved at the base station using a selected beam direction, and the transmission power setting is determined based on transmission parameters of the UE and reception parameters of the base station, and on channel characteristics. The UE is to initiate transmission of the signaling using the transmission power setting for the plurality of directional beams, wherein the signaling is transmitted to be received according to a targeted received signal characteristic to be achieved at the base station.
