Embodiment

[0093] What is claimed is: 1. A method for millimeter wave (mmW) beam acquisition implemented at a wireless transmit / receive unit (WTRU), the method comprising transmitting millimeter wave (mmW) WTRU (mmW WTRU) information to a base station over a cellular system.

[0094] 2. The method of embodiment 1, further comprising receiving a list of candidate mmW base stations (mBs) including mmW acquisition start timing information.

[0095] 3. The method of any preceding embodiment, further comprising calculating a correlation value for the mB in the candidate list based on the received mmW acquisition start timing information.

[0096] 4. The method of any preceding embodiment, wherein the mmW acquisition start timing information includes coarse timing information related to cellular system timing.

[0097] 5. The method of any preceding embodiment, further comprising receiving at least one of: a beam scan repetition number, an mB and beam-specific index corresponding to the signat...

Abstract

Methods and apparatus for establishment of a milli-meter Wave (mmW) link communication include initial selection of candidate mmW Base stations (mBs) and configuration of mmW acquisition resources and procedures, both with the assistance of the cellular network. Further methods transmit mmW acquisition beacons, process mmW acquisition beacons to achieve mmW beam alignment and timing synchronization, and uplink (UL) reporting via cellular or mmW links. In an example, a mmW wireless transmit/receive unit (WTRU) transmits millimeter wave (mmW) WTRU (mmW WTRU) information over a cellular system to a base station, receives a candidate list of candidate mmW base stations (mB) including mmW acquisition start timing information and calculates correlation values around the received mmW acquisition start timing information for the mBs in the candidate list. The mmw WTRU performs sliding window correlations by using signature sequences corresponding to mBs and beams in the candidate list.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of US Provisional Application No. 61 / 568,639, filed December 8, 2011, the contents of which are incorporated herein by reference. Background technique [0003] The 3rd Generation Partnership Project (3GPP) introduced Long Term Evolution (LTE) to increase cellular network bandwidth for expected mobile data demands. However, the planned growth in mobile data demand could export even LTE-Advanced (LTE-A) capacity. The transfer of high-speed mobile data can be implemented using millimeter waves (mmW). For example, further generation of high-speed mobile data can be delivered using 60GHz mmW. SUMMARY OF THE INVENTION [0004] Methods and systems for millimeter wave (mmW) communication systems are described herein. The method includes initial selection of candidate mmW base stations (mBs) and configuration of mmW acquisition resources and procedures, both with the assistance of the cellu...
