    • The present invention is a method and system for supporting a beamforming antenna system in a mobile broadband communication network with an improved beam pattern, beam sweep pattern, pilot channel design with feedback and reporting rules, and control signaling design. Specifically, the improved beam pattern includes a method of supporting wireless communications in a wireless network forming at least two spatial beams within a cell segment where the at least two spatial beams are associated with different power levels, and separately, where at least two spatial beams can be moved across the cell segment according to a unique sweep pattern. The pilot channel design improves network bandwidth performance and improve user mobility tracking. Feedback and reporting rules can be established using a particular field designator, CQI, in the preferred embodiment.

    • Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EU-TRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for POSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and POSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.
    • 通过对于用于到达时差(TDOA)的信号引入非单位频率重用,可以通过包括可以在低灵敏度和低信噪比下检测的附加参考信号来提高邻近小区的可听性, 测量,例如从服务小区站点和各个相邻小区站点发送的信号的正交性。 提出了称为TDOA-RS的新参考信号,以提高部署3GPP EU-TRAN(LTE)系统的蜂窝网络中相邻小区的可听性,并且可以在任何资源块(RB)中传输TDOA-RS, 用于POSCH和/或MBSFN子帧,而不管后者是否在支持PMCH和POSCH的载波上。 除了附加的TDOA-RS参考信号之外,还可以包括附加同步信号(TDOA-sync)以提高相邻小区的可听性。
