The present invention provides a wireless access control method, relay station and base station. The wireless access control method according to the present invention is characterized in that under the control of said base station, information of said subscriber station and said base station is received and forwarded via a wireless channel by using the relay station. Said method further comprises the steps of: uplink bearer data and control information from said subscriber station being first received by said relay station and then forwarded to said base station; downlink bearer data from said base station being first received by said relay station and then forwarded to said subscriber station. Said base station sends control information directly to the subscriber station. The present invention further comprises a relay station for implementing the above method and an improved base station. In the method and devices provided by the present invention, with the introduction of relaying access technique, subscriber stations located with the long distance to the base station or in shadowing areas may be connected by relaying.

A self-adaptive jitter buffer adjustment method for packet-switched network is presented in this invention, which involves both positive adjustment to jitter buffer and negative adjustment to jitter buffer. The positive adjustment part performs a positive adjustment to the jitter buffer according to an indication of a sequence number of the packet delaying, to absorb larger network jitters by dynamically detecting sequence numbers of the packets in the jitter buffer. The negative adjustment part performs a negative adjustment to the jitter buffer when the filling level descends, to match smaller network jitters by periodically detecting a filling level of the jitter buffer. This invention realizes the dynamic tracking of network jitter, so that a self-adaptive adjustment to the jitter buffer working parameters can be achieved. Comparing with traditional methods for self-adaptive buffer adjustment, the present method reduces the complicacy and computational costs of the self-adaptive jitter buffer adjustment algorithm. At the same time, the impact of self-adaptive jitter buffer adjustment on the performance of the entire system is greatly reduced.

The invention relates to methods and devices for setting up connection for wireless relay network, wherein, mobile station utilizes the primary transmission path from itself and relay stations in the initial ranging and network entry procedure to send a request signal to base station. After the base station receives the request signal, it allocates a transmission path for the mobile station, and sends the information to the relay station on the path along the primary transmission path, and sends a response message to the mobile station. When the mobile station and the related relay stations obtain the corresponding response message and transmission path information, the signal sent by the mobile station is sent to the base station via relay stations along the transmission path.

The present invention discloses a method and a base station for allocating bandwidth for subscriber stations and a backhaul station through taking into joint consideration uplink and down bandwidth requests from respective subscriber stations in a wireless single-hop self-backhaul network. Upon receipt of information on bandwidth requests from the subscriber stations, the base station takes uplink and downlink bandwidth requests into joint consideration, allocates bandwidth for the subscriber stations and the backhaul station, and then notifies the subscriber stations and the backhaul station. Since bandwidth allocation is no longer based on uplink and downlink resources separately, a relatively high system bandwidth utilization ratio can be achieved and uplink and downlink bandwidth fairness for asymmetric traffic be ensured even if the network is overloaded.
