摘要： The method for transmitting information in the wireless relay system includes the step that the information sent between the source node to the target node is relayed by several RSs. The RSs can send information in the same time-frequency field or different time-frequency field. The target node decodes the information from the RSs simultaneously when the information is in the same time-frequency field. Then the target decodes the information respectively from the different time-frequency field, and connects each information decoded to obtain the result. A system for transmitting information in the wireless relay system is given at the same time. The method and system above can improve the reliability of link transmitting, balance the load among RSs, and improve the QoS of the target node.

摘要： A paging method, a wireless network, a base station and a relay station in the wireless communication field are disclosed, which enable the terminal to be paged normally when there are relay stations in the network. In the present invention, the base station or the relay station starts paging in its own coverage area and sends down the paging message level by level upon receiving the paging message of a terminal in idle mode. The base station or the relay station can send down the paging message to the lower level relay station after it has received the paging message of a terminal in idle mode; it can also start paging first in the coverage area of the base station or the relay station, if it doesn't received the response message in a predetermined time period, it will send down the paging message to the lower level relay station. The relay station or base station stops sending down the paging message when it has received a location update request or network re-access request from the lower level relay station or from the terminal or when the paging times has reached the maximum paging times; the relay station can also stop sending down the paging message upon receiving a stopping paging message from the higher level relay station or base station.

摘要： A method for implementing the random access of the new access node and its system are disclosed, which belong to the wireless communication field, and which enable the new access node within the coverage of the relaying station implementing the random access. In the application, when a new access node is located within the coverage of the relaying stations, each of the relaying stations would inform a synchronization station of the access request sent by the new access node via a report message, the synchronization station compares the access request forwarded by the respective relaying stations and the access request received by itself fromthe same new access node, selects the station with the best received signal quality of the access request, and completes the access of the new access node in accordance with the types of the selected station and the synchronization station itself.

摘要： The present invention discloses a method for switching in a wireless relay system, the method comprises: a relay station RS monitors dynamically up-link signal quality of terminal MS, and reports the signal quality to a serving station; the serving station determines an anchor RS from the RS reporting up-link signal quality of MS according to up-link signal quality information reported by the RS; judges whether the anchor RS changed, if not, the RS normally runs, continues to monitor up-link signal; or switches to a new determined anchor RS to forward serving data between the serving station and the MS. In additional, the present invention also discloses a wireless relay system for implementing switching. The method and system supplied by the present invention can realize switching between the RS and the BS in the case that the MS don't know presence of the RS.

摘要： A method for HARQ in a communication system including a relay station is provided. The method comprising the following steps: a terminal or a base station sends the data block to the opposite, then the relay station returns the receiving status to the sender after it has sent the data block, finally the sender determines whether there is a need to retransmit the data block. An HARQ system including a base station and a relay station and a terminal is also provided. A relay station including a receiving module and a setting module and a forwarding module is also provided. HARQ in the communication including a relay station is realized, thus the performance of the system is improved and the transmission quality is improved; at the same time, the transparency of the relay station for the terminal is realized and the compatibility of the system is ensured for the traditional terminal without changing the existing terminal in the system including a relay station.

摘要： A method for starting and stopping the relay function of a relay station in a wireless communication system, in which both the relay station and the base station can send out the request for starting or stopping the relay function of the relay station, firstly the relay station negotiates with the base station to start or stop the relay function of the relay station, and then the relay station determines to set its operation mode as relay or terminal mode according to the negotiation result. A relay station sets its own operation mode according to the received request message for starting or stopping the relay function. It realizes the remote control to the operation state of the relay station, and at the same time provides the convenience for the user to control the relay station of which the user possesses.

摘要： A dual-mode relay station and a network access method, a mode conversion method and a control station thereof are provided. When it is accessing a network, the dual-mode relay station negotiates with its control station to determine whether accessing the network in a terminal mode, if it is selected that accessing the network at a terminal mode, after it accesses the network, a relay function of the dual-mode relay station can be activated based on service and network demand, and it is converted to be the relay mode and works. The dual-mode relay station and the control station both can initiate a request for activating the relay function of the dual-mode station. In the mode conversion process, firstly, the relay station and the base station negotiate to active the relay function of the dual-mode relay station, and negotiate a suitable path for activating the relay station. Then, the dual-mode relay station determines whether setting the work mode of the dual-mode relay station to the relay mode based on the negotiation result. The technical proposal realizes a flexible control of the relay station work mode, and there is dominance in the utilization of the non-fixed relay communication system, for example, nomadism and mobile, especially.
