Abstract: Disclosed are methods for prompt re-direction of uplink access of a specific user equipment and controlling random access. Specifically, for initial random access to a network, if a user equipment (UE) transmits a preamble (S201), which includes information related to random access, to a network node, the network node sends grant/rejection information of the preamble and re-direction information as a response message to the preamble (S203) to the UE.

Abstract: A method of generating a data block for performing a polling procedure in a wireless communication system, a method of transmitting data and a method of performing a polling procedure are disclosed. A protocol layer performs the polling procedure for requesting a receiving side to transmit status report if there are no data to be transmitted to the receiving side in both a transmission buffer and a retransmission buffer. When determining whether there are no data to be transmitted to the receiving side in the retransmission buffer, it is preferable that a data block for which retransmission request information is not received from the receiving side is excluded.

Abstract: A method for transmitting radio resources in a mobile communication system is disclosed. The method includes receiving a random access channel (RACH) preamble from a plurality of UEs and transmitting response information associated with the received preambles over a common channel wherein the plurality UEs can access the common channel and receive corresponding information. If a HARQ scheme is used when a UE transmits data to the eNode-B using uplink radio resources allocated over the RACH, the eNode-B does not pre-allocate uplink radio resources required for re-transmission and performs allocation of radio resources for a first transmission of HARQ. If the re-transmission is required, the eNode-B allocates the radio resources required for the re-transmission with the NACK signal. If re-transmission is not required, the present invention can reduce an amount of wasted radio resources.

Abstract: A user equipment (UE) and method are provided for transmitting an in-device coexistence (IDC) indication message in a wireless communication system. The UE receives a configuration message including an IDC indication from a base station. The UE transmits an IDC indication message to the base station if the UE determines that the IDC indication contains specific information. The specific information comprises an activation bit. The presence of the activation bit in the configuration message represents permission for the UE to transmit the IDC indication message. The IDC indication message includes frequency division multiplexing (FDM) assistant information. The FDM assistant information includes information on an unusable frequency in which interference from a long-term evolution (LTE) module in the UE to other coexisting technology modules in the UE or interference from other coexisting technology modules in the UE to the LTE module in the UE is expected.
