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.
