摘要： A wireless communication system has a protocol enabling synchronous code division multiple access (CDMA) communication on a time division duplex (TDD) frequency, and provides for a smart antenna system as an integral component of the system. The protocol has downlink time slots (DTS) (302, 306) which provide for synchronization and paging of all remote terminals (10, 20, 30) from a base station (50) and on an omnidirectional code channel and while providing for traffic signals on directional traffic channels. The protocol has uplink time slots (UTS) (304, 308) which enable rapid link request by remote terminals (10, 20, 30), as well as enabling improved spacial estimation, synchronization and power control of remote terminals by the base station (50).

摘要： The present invention relates to, a pain control method for user terminal employed when cell perform initial searching in a TD-SCDMA mobile communication system. First, the user terminal receive and record data of plurality of subframe by BS transmitted in the case of receiver have maximum gain for each carrier frequency; Search the position of Downlink Pilot Times Slot (DwPTS) of plurality of subframe using time window determine method; Continue perform later process of cell initial searching when acquired the position of DwPTS; Determine whether receiver is saturated when not acquired the positon of DwPTS; lf receiver is saturated, decrease gain of receiver and continue receive and record data of plurality of subframe by BS transmitted; If receiver is not saturated, determine no BS adapt to currently carrier frequency. Repeat perform above discribed cell initial searching process, until the receiver is not saturated. The present invention can speedy complete cell initial searching in the condition of ADC of user terminal in a limit dynamic range
