Problems solved by technology

The non-harmonized beacon transmission interval (non-harmonized beacon transmission interval) between access points (AccessPoint, AP) brings high network discovery delay, which will lead to long network reselection time, so it is not conducive to service continuity

Embodiment Construction

[0035] Some embodiments of the invention will now be described in detail, some examples of which are illustrated in the accompanying drawings.

[0036] figure 1 is a schematic diagram of a control beam (Control Beam, CB) in a beamforming mmWave cellular network 100 according to one novel aspect. The beamforming network 100 includes a base station (BaseStation, BS) 101 and a user equipment (UserEquipment, UE) 102 . mmWave cellular networks use narrow beams for directional communications and can support multi-gigabit data rates. Directional communication may be accomplished by digital and / or analog beamforming, where multiple sets of beamforming weights are applied to multiple antenna elements to form multiple beams. For control purposes, a coarse set of TX / RX control beams is provided by the base station in the cellular system. The set of control beams may be configured periodically, or occur indefinitely and repeat in an order known to the UE. The set of control beams cov...

Abstract

A method of control signaling in a beamforming system is proposed. A user equipment (UE) receives control beam transmission from a base station using a set of control beams in a beamforming network. Each control beam comprises a set of DL control resource blocks, a set of UL control resource blocks, and an associated set of beamforming weights. The UE selects a control beam for establishing a connection with the base station. The UE then performs random access with the base station using the selected control beam.

Description

[0001] cross reference [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application 62 / 054,485, filed September 24, 2014, entitled "Control Signalingina Beamforming System," and U.S. Application 14 / 723,706, filed May 28, 2015, The above application is hereby incorporated by reference. technical field [0003] The present invention relates to wireless communications, and more particularly to control signaling and synchronization in millimeter wave (mmW) beamforming systems. Background technique [0004] The increasing shortage of mobile carrier bandwidth in next-generation broadband cellular communication networks has prompted the exploration of the underutilized mmWave spectrum between 3G and 300 GHz. The available spectrum in the mmWave band is two hundred times larger than that of traditional cellular systems. mmWave wireless networks use narrow beams for directional communications and can support multi-gigabit data rates. The bandwidt...
