Incremental Scheduling for Wireless Communication System with Beamforming

摘要

An incremental scheduling scheme is proposed in a wireless communication system with beamforming. In an initial stage (stage-1), coarse scheduling plan is granted via control beam transmission. In a second stage (stage-2), fine scheduling plan is granted via dedicated beam transmission. Such incremental scheduling scheme provides load balancing for overhead channels on control/dedicated beams via stage-2 scheduling. It utilizes dedicated beam transmission that is more resource efficient and more UE-specific. Furthermore, it provides UE natural power-saving opportunities via stage-1 scheduling.

1. A method comprising:
(a) allocating a set of control resource blocks by a base station in a beamforming mobile communication network, wherein the set of control resource blocks are associated with a set of control beams; (b) allocating a set of dedicated resource blocks associated with a set of dedicated data beams, wherein the control resource blocks and the dedicated resource blocks are time division multiplexed (TDM) in time domain; (c) providing coarse scheduling information to a user equipment (UE) via control beam transmission; and (d) providing fine scheduling information to the UE via dedicated data beam transmission.
