摘要:
Provided is a device and method for scheduling uplink resources in a wireless communication system supporting VoIP . When its data rate is decreased, an MS notifies a BS of the rate decreased. When increasing its data rate, the MS requests resource allocation to the BS by transmitting a BR header or a CQICH codeword. Compared to the conventional ertPS in which the BS periodically allocates uplink resources to the MS irrespective of the state of the MS, the BS does not allocate uplink resources when the MS transitions form a talk-spurt period to a silence period. Therefore, resources consumption arising from unnecessary bandwidth allocation is reduced.

Provided is an apparatus and method for transmitting frame information in a wireless communication system using a relay scheme. In a method for transmitting frame information from an upper node in the wireless communication system, downlink section information for communication with the lower relay station for a relay service is transmitted to a lower relay station at the request of the lower relay station for an initial connection. After the initial connection, frame information for communication with the lower relay station for a relay service is transmitted to the lower relay station through the downlink section.

An apparatus and a method for supporting multiple links in a multi-hop relay cellular network using at least two frequency bands are provided. A subframe for a link on which a Mobile Station (MS) or a Relay Station (RS) communicates with a Base Station (BS) is configured in a first frequency band, and a subframe for a link on which the BS or the RS communicates with the MS is configured in a second frequency band.
摘要:
A method and apparatus for supporting a Short Message Service (SMS) of a Mobile Station (MS) during an idle mode in a wireless communication system are provided. An MS operation method for supporting an SMS in a wireless communication system includes receiving an SMS message from a Base Station (BS) through a ranging message in an idle mode, upon receiving the SMS message from the BS, initiating a timer, while the timer operates, waitUpLink (UL) resource allocation for transmission of an ACKnowledge (ACK) message about the SMS message, and upon being allocated a UL resource for the ACK message transmission and transmitting the ACK message using the UL resource.
摘要:
An apparatus and method for transmitting and receiving a signal according to a change of downlink channel information by a mobile station in a broadband wireless access communication system. The method includes: detecting the change of the downlink channel information; receiving a report from a base station that there is data for the mobile station; and reporting the change of the downlink channel information to the base station, so that the base station and the mobile station have same downlink channel information.

Disclosed is a method for performing a network re-entry operation by a target base station (BS). The method includes detecting that a mobile station (MS) is to perform a handover to the target BS; and transmitting to the MS handover process optimization information, included in a Ranging Response (RNG-RSP) message, indicating a possibility of omitting at least one of a process of transmitting a registration response (REG-RSP) message from the target BS to the MS, and a process of transmitting a subscriber station basic capability response (SBC-RSP) message from the target BS to the MS, required by the MS to perform a network re-entry operation with the target BS due to the handover of the MS, wherein if the at least omitted one process is the process of transmitting the REG-RSP message, the handover process optimization information includes information indicating that the target BS omits the process of transmitting the REG-RSP message to the MS, and wherein if the at least one omitted process is the process of transmitting the SBC-RSP message, the handover process optimization information includes information indicating that the target BS omits the process of transmitting the SBC-RSP message to the MS.
