    摘要： Systems and methods of pre-allocating identifiers to wireless devices for use in requesting resources over a random access channel are described. A wireless communication system includes a random access channel over which wireless devices can anonymously send requests for resources. The base stations receiving and processing the anonymous requests reduces the probability of random access channel collisions and conserves the resources needed to support the anonymous requests by pre-allocating one or more codes to select wireless devices. The wireless devices having the pre-allocated codes can transmit a particular code over the random access channel as a request for resources that uniquely identifies the requestor.

    摘要： In a synchronization judging circuit, a measuring portion measures a signal to interference power ratio of a received signal at each frame. An averaging portion calculates a moving average of a series of signal to interference power ratios for a predetermined number of frames to produce a mean value at each frame. A counter counts a number of consecutive frames each of which the mean value meets a predetermined threshold requirement. The counter further compares a counted value with a predetermined threshold value to decide whether to perform a transmission control operation or not.

    摘要： In a CDMA communication network, a first signal is transmitted from a base station to a mobile station, and a reply message is transmitted from the mobile station to the base station at the timing indicated by the first signal. At the base station, the actual timing of the reply message from the mobile station is repeatedly measured, and a timing signal repeatedly generated by detecting the timing difference between the measured actual timing and the expected timing of the reply message from the mobile station. The timing signal is repeatedly transmitted to the mobile station. Each mobile station comprises a repeatedly-adjustable delay circuit (53) for synchronizing an adjusted spread spectrum pattern accordingly.

    摘要： A method for initial synchronization with TD-SCDMA system in the connection mode of GSM system, to resolve the problem of the downlink synchronization codes (DwPTS) may be undetectable or taking too much time to be detected when a TD-SCDMA/GSM dual-mode terminal is examining TD-SCDMA frames in GSM connection mode with prior art; in the connection mode of the GSM system, the method receives or transmits service data within the service time slots of the GSM frame at the radio frequency band of the GSM system, and receives TD-SCDMA signal within the idle time slots of the GSM frame at the radio frequency band of the TD-SCDMA system, and detects DwPTS in the received TD-SCDMA signal, thus the terminal in the connection mode of the GSM system can quickly detect the DwPTS in TD-SCDMA frames, achieving the initial synchronization of the TD-SCDMA/GSM dual-mode system. A GSM system processing apparatus and a communication apparatus are also disclosed in the invention.
