摘要： The present invention provides a method of using a relay station to assist processing of requests from user ends (UEs), comprising: the relay station acquires and monitors channel resource information received from a base station; upon receiving a request from the UEs via the channel resource, the relay station sends the request received to the base station if it detects no response from the base station to the request. The present invention further provides an apparatus of using a relay station to assist processing of requests from UEs, comprising a channel resource acquisition unit for acquiring channel resource information from the base station; a user monitoring unit for monitoring the channel resource acquired by the channel resource acquisition unit and for receiving requests sent from the UEs; a base station monitoring unit for monitoring response from the base station to the requests upon receiving the requests sent from the UEs; a transmitting unit for sending the request to the base station when no response from the base station to the request is detected.

摘要： This invention provides a type of method used for providing channel aware relays in enhanced relay clusters. This method is based on the Centralized Cluster Relay Implementation Proposal, and is implemented by transferring MMR-BS channel information based functions to RS. Specifically, in this invention, RS receives authorization from the MMR-BS to receive the channel information from the MS or next single-hop RS point within its single-hop range, and, after performing applicable channel aware relays, reports the processing result to MMR-BS; MMR-BS configures the signal according to the processing result and joins RS to transmit the control signal to the cluster MS. Using the method provided by this invention can reduce the channel overhead between MMR-BS and RS, and at the same time ensure that the RS composition is simple, and the production costs are low.

摘要： The present invention provides a method for changing a route in wireless communication, and this method comprises the following steps: when there is subscriber equipment requesting a change of route in a cell, a base station negotiates downlink measurement contents with a relay station facilitating the route change in the cell; a network side informs the subscriber equipment requesting a change of route of the negotiated downlink measurement contents, and the subscriber equipment executes a downlink measurement according to the received measurement contents and reports the downlink measurement results to a radio access point; and the radio access point executes the route change for said subscriber equipment according to the received measurement results. The present invention can effectively improve the accuracy of the route change and alleviate the delay due to the route change.

摘要： Method and Node according to the inventive technique wherein support of a quality of service is provided for transmissions between at least one node (N) and at least one mobile station (MS1) in a multihop communication environment. Support is ensured by checking the quality of service class of each transmission prior to transmission. Once the checking has been performed, depending on the class of the checked transmission a multihop transmission or a direct transmission is selected for the transmission to the at least one mobile station, whereby a transmission having a quality of service class belonging to a first class of quality of service classes is transmitted using the direct transmission, whereas a transmission having a jquality of service class belonging to a further class of quality of service classes is transmitted using the multihop transmission.

摘要： The invention relates to a method for regulating random accesses in a radio-assisted local network comprising at least one access point (AP), a first radio station (QSTA2; QSTA3) located in the radio coverage area of the at least one access point (AP), at least one remote radio station located both outside the radio coverage area of the at least one access point (AP) and inside the radio coverage area of the first radio station (QSTA2; QSTA3), and optionally other radio stations located inside the radio coverage area of the at least one access point (AP), the at least one access point (AP) temporarily allocating radio resources (RPOLLQSTA2, RPOLLQSTA3), for sending information, to radio stations (QSTA2, QSTA3) inside the radio coverage area thereof, and radio stations (QSTA2, QSTA3) temporarily operating a random access to radio resources for sending information. According to the invention, the first radio station (QSTA2; QSTA3) sends a signal to the at least one remote radio station, containing information on the permissibility of a random access of the at least one remote radio station. The inventive method enables random accesses of remote radio stations to be granted and rejected, whereby random accesses can be efficiently implemented in a radio-assisted local network with remote radio stations.

摘要： The invention relates to a method for transmitting a sequence of data in a communication system, wherein a first transmitting station (S1) transmits a transmission signal (C(t)) to a first receiving station (R1) for transmitting the sequence of data via a radio interface (V). The radio interface is monitored with respect to an interference signal (I(t)) from an interference source (S2) prior to transmission via at least the first transmitting station (S1) and/or the first receiving station (R1). The transmission only begins if the radio interface (V) is sufficiently free from interference at a moment in time (T0).

摘要： A mobile communication data transmission method for a cell having one base station and more than one relay station involves switching the relay stations between at least two operating modes of signaling transmission under the control of the base station. A system transmits mobile communication data in a cell having one base station and more than one relay station. When transmitting an uplink signaling or a downlink signaling, the relay stations switch between at least two operating modes under the control of the base station. By using the method, network, relay station, and base station, data transmission in multiple modes can be achieved, so as to achieve a flexible relay scheme.

摘要： The invention relates to a method for the organisation of a radio communication system comprising a plurality of subscriber radio stations (1, 2, 3, 4, 5, 6) having, respectively, a radio transmission range (C), and a central radio station (Z). The subscriber radio stations (1, 2, 3, 4, 5, 6) are at least partially mobile and each radio station (Z, 1, 2, 3, 4, 5, 6) is disposed within the radio transmission range (C) of at least one adjacent subscriber radio station (1, 2, 3, 4, 5, 6). User data is sent from radio station (Z, 1, 2, 3, 4, 5, 6) to radio station (Z, 1, 2, 3, 4, 5, 6,) within the range (C) of a subscriber radio station (1, 2, 3, 4, 5, 6) in order to transfer user data. User data can be transferred directly or can be transferred via one or several other radio stations (z, 1, 2, 3, 5, 6,) from any particular first subscriber radio station (1, 2, 3, 4, 5, 6) to any particular second subscriber radio station (1, 2, 3, 4, 5, 6) in the radio communication system. According to the invention, the central radio station (Z) transmits information via the adjacent subscriber radio stations (1, 2, 3, 4, 5, 6) of each subscriber radio station (1, 2, 3, 4, 5, 6) within at least one part of the radio communication system to the plurality of subscriber-sided radio stations (1, 2, 3, 4, 5, 6) within the at least one part of the radio communication system. According to the inventive method, signalling costs in ad hoc networks can be reduced.

摘要： The invention relates to a method for allocating radio communication resources (R1, R2) in an at least partially self-organising radio communications system comprising several user stations (MT1, MT2, MT3, MT4, MT5). Said radio communications system comprises at least one central entity (AP/CC) for organising the allocation of radio communication resources (R1, R2), in addition to a corresponding radio communications system. According to the invention, resources (R1) for direct communication between at least two respective user stations (MT1, MT2; MT4, MT5) are allocated repeatedly at least partly by the central entity (AP/CC).
