摘要： A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.

摘要： The present invention provides a method for transmitting and receiving random access channel messages in an extended range wireless communication system. One embodiment of the method may include accumulating, at a base station, signal energy received during a first portion of a transmission time interval. The method may also include accumulating, at the base station, signal energy received during a second portion of the transmission time interval. The first and second portions are offset from the start or end of the transmission time interval by selected delay intervals. The method may further include detecting the message(s) based on the signal energy accumulated during the first and second portions of the transmission time interval.

摘要： A method is provided for maintaining synchronization between an AT and a base station during an idle period. During the idle period, a reduced number of uplink reference signals for uplink channel quality estimation are sent to the base station by the AT. The uplink reference signals are sent to assist coherent demodulation and uplink channel quality estimation for scheduling. During the uplink idle period, the numbers of uplink reference signals are designed to be reduced in selective coherent bandwidths. The selection of the coherent bandwidth alternates in time and covers the entire spectrum to allow the channel quality estimation through the entire spectrum.

摘要： A method is provided for controlling a wireless communications system. The method comprises communicating data to a first base station, and selecting a switchover time for ceasing communications with the first base station and beginning communications with a second base station. The switchover time is based on channel conditions associated with the communications to the first and second base stations, such as SIR.

摘要： In the UMTS, semi-static uplink and downlink connection parameters relating to the frequently-used services of voice, fax and web browsing are intermittently broadcast to mobile user equipment (20) which stores the parameters. When a mobile requests (30) one of those services, the relevant dynamic parameters are sent (32) over the radio interface and the mobile is asked whether it has in its store the relevant parameters for the requested service; if so (34), the call is set up; if not (36), the semi-static parameters relevant to the requested service are sent (38) to the user equipment. Considerable saving of radio resource results.
摘要翻译： 在UMTS中，与语音，传真和网页浏览的频繁使用的服务相关的半静态上下行链路连接参数被间歇地广播到存储参数的移动用户设备（20）。 当移动请求（30）这些服务之一时，通过无线电接口发送（32）相关的动态参数，并且询问移动台是否在其存储中存储所请求的服务的相关参数; 如果是（34），则建立呼叫; 如果不是（36），则将与请求的服务相关的半静态参数发送（38）到用户设备。 大量节省无线电资源成果。
