摘要:
Provided is a method for transmitting/receiving data in a communication system providing Multicast/Broadcast Service (MBS). The method includes, generating transmission data to be transmitted to a receiver; allocating the transmission data to a frame; setting a MAP message that includes information on a frame offset related to the frame; and transmitting to the receiver the MAP message.
摘要:
A method for controlling an idle mode in a broadband wireless access (BWA) communication system. A mobile station (MS) transmits to a base station (BS) a de-registration request (DREG-REQ) indicating a state transition request to the idle mode. The BS transmits to the MS a de-registration command (DREG-CMD) for commanding state transition to the idle mode. The MS transmits to the BS a de-registration acknowledgement (DREG-ACK) in response to the DREG-CMD.
摘要:
A method for allocating a channel quality information channel (CQICH) in a communication system is disclosed. After fast switching from a serving anchor base station (BS) to a target anchor BS, a mobile station (MS) detects absence of a CQICH allocated from the target anchor BS. Upon detecting the absence of the allocated CQICH, the MS sends a request for allocating the CQICH to the target anchor BS. Upon receiving the CQICH allocation request, the target anchor BS detects a need to allocate a CQICH to the MS.
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.

摘要:
A broadband wireless access communication system including a serving BS that periodically broadcasts an MOB_NBR-ADV message to an MS, and different kinds of heterogeneous networks. In order to communicate using the neighbor Base Station (BS) information, the serving BS gathers information about neighbor BSs and determines if heterogeneous communication systems exist using the gathered information. If the heterogeneous communication systems exist, the serving BS includes the information about the heterogeneous communication systems in the MOB_NBR-ADV message and broadcasts the MOB_NBR-ADV message to an MSS. If the MOB_NBR-ADV message is received from the serving BS, the MSS identifies if the heterogeneous communication systems exist using the MOB_NBR-ADV message.
摘要:
A method for requesting allocation of a Channel Quality Information Channel (CQICH) by a Mobile Station (MS) in a communication system. The method includes switching, by the MS, from a serving anchor Base Station (BS) to a target anchor BS, detecting an absence of a CQICH allocated from the target anchor BS, and transmitting, from the MS to the target anchor BS, a CQICH allocation request. The CQICH allocation request includes a CQICH allocation request header including a basic Connection IDentifier (CID) of the MS and a Header Check Sequence (HCS) for the CQICH allocation request header.
摘要:
A broadband wireless access communication system including a serving BS which broadcasts a MOB_NBR-ADV message to an MS is provided. A method for configuring the MOB_NBR-ADV message is also provided, and includes adding a specific field, which represents whether at least one information field constituting the MOB_NBR-ADV message exists, to the MOB_NBR-ADV message, determining if at least one information field is included in the MOB_NBR-ADV message, and determining a bit value of the specific field according to whether at least one information field is included in the MOB_NBR-ADV message.
