摘要： A contention-based uplink data transmission method, apparatus and system are provided. The method may include that: a main control node in a communication system receives data transmitted via uplink contention transmission resources, and decodes the data, wherein the uplink contention transmission resources are uplink transmission resources which the main control node allocates to a plurality of terminal nodes in the communication system and via which the plurality of terminal nodes transmits data in a contention-based way; and the main control node sends reception status information to each terminal node transmitting the data via the uplink contention transmission resources, wherein the reception status information reflects whether the data transmitted from each terminal node has been decoded successfully.

摘要： A radio base station improved in the efficiency of processing random accesses from mobile stations. The radio base station designates a random access signal when transmitting downlink data to a mobile station. The mobile station transmits the designated random access signal to the radio base station. The radio base station transmits, to the mobile station, timing adjustment information prepared based on the result of reception of the random access signal and allocation information about an uplink radio resource allocated to the mobile station. If there is control data to be transmitted to the radio base station, the mobile station transmits the control data by using the allocated uplink radio resource, and if there is no control data to be transmitted, the mobile station transmits a synchronization completion report prepared in reply to the timing adjustment information.

摘要： During handover, an origin base station saves data packets for a mobile station, as well as instructs the mobile station to switch communication to a destination base station, and requests a host station to switch the base station that communicates with that mobile station from the origin base station to the destination base station. After that, when in accordance to the switching request it is possible to save data packets, the host station begins to save the data packets for the mobile station in the place of the origin base station, and after communication between the mobile station and the destination base station has become possible, sends the saved data packets to the mobile station via the destination base station.

摘要： A wireless communication system comprises a mobile station and a base station, which use a plurality of communication channels and a pilot channel corresponding to at least one of the communication channels. The base station has a transmitting unit that employs at least one of the communication channels as a priority channel and transmits channel information of this priority channel and the other channels by use of a communication channel other than the pilot channel. The mobile station has a determining unit that determines a reception level of the pilot channel; an acquiring unit that acquires the channel information transmitted via the communication channel other than the pilot channel; and a deciding unit that decides, as an available communication channel, at least one of the communication channels based on both the channel information acquired by the acquiring unit and the reception level determined by the determining unit.
