摘要： A system and method for using a pilot signal in a communication receiver having multiple antenna elements is described. A set of data signals and a set of pilot signals are received (600). A first pilot signal from the set of pilot signals is identified based on a first characteristic of the first pilot signal from the set of pilot signals (640). A set of weight values associated with the antenna elements are adjusted so that a second characteristic of the first pilot signal is substantially optimized with respect to the second characteristic of the remaining pilot signals from the set of pilot signals (650). Consequently, a first data signal from the set of data signals and being uniquely associated with the first pilot signal is substantially optimized by the adjusting of the set of weight values associated with the antenna elements.

摘要： The present invention relates to a method of cell initial search in CDMA digital mobile telecommunication system. The method includes: the terminal obtains the downlink synchronization with a base station after selecting the operating frequency; correcting the carrier departure between the base stations in digital demodulator. The downlink synchronization includes: judging a scope of downlink training sequence time slot (DWPTS) by using the method of training sequence power feature window value; in this scope, obtaining the exact location of terminal reception by finding out the correlation between the received data and the training sequences. The step of correcting carrier departure between terminals and base station includes: estimating carrier departure using software, and adjusting hardware using the judge feed method, recovering the carrier departure using the carrier departure correction method based on the combined detection.

摘要： In a mobile communication system (T1) a data transmission determining means (DTDM) located in a subscriber station (MS) estimates a predetermined time interval in which no-data transmission will be directed from the base transmitter station (RBS) to said subscriber station (MS). An IF measurement means (IFMM) performs inter-frequency measurements necessary for handover procedures in the predetermined time interval in which no data transmission takes place. The determination of the no-data transmission is done autonomously by the subscriber station (MS) without the need of exchanging signalling or other data with the network control means (RNC). The invention is particularly useful for CDMA, WCDMA and TDMA mobile radio communication systems.

摘要： A mobile station accesses a base station by randomly selecting a first reverse link common control channel from a set of random access channels. The mobile station transmits a request portion of an access probe over the first reverse link common control channel. The request portion is subject to collision with other signals. The request portion comprises a hash identification which is derived from a uniquely identifying number using a hash function. The hash identification quasi-uniquely identifies the mobile station. The mobile station receives a channel assignment message from the base station designating the hash identification and a reserved access channel. The reserved access channel provides communication with a low probability of contention. The mobile station transmits a message portion of the access probe over the reserved access channel.

摘要：本申请公开了一种发送信号的方法，包括：发送端向接收端发送参考信号，该参考信号的发射功率为P 1 ；发送端向接收端发送数据信号，该数据信号的发射功率为P 2 ；发送端再次向接收端发送该参考信号，该参考信号的再次发射功率为P 3 ，P 3 大于P 1 ，且P 3 与P 1 的差值的绝对值为Δ1；发送端再次向接收端发送该数据信号，该数据信号的再次发射功率为P 4 ，P 4 大于或等于P 2 ，P 4 与P 2 的差值的绝对值为Δ2，Δ2小于Δ1。根据该方法，对数据信号采用较小的功率爬坡步长可以减小因数据信号的发射功率过大造成的对其它设备的干扰，与此同时，增大参考信号的发射功率以及重复传输参考信号和数据信号可以增强参考信号和数据信号的传输可靠性。
