摘要:
A method for controlling a sleep-mode operation in a communication system is provided, in which a Mobile Station (MS) transitions to an awake state in a listening interval of the sleep mode, performs one of a first operation, a second operation, and a third operation in the awake state, and transitions to a sleep state if the MS determines that there is no data to transmit to a BS and no data to receive from the Base Station (BS) after the one operation is performed. The first operation is for receiving data from the BS, the second operation is for transmitting data to the BS, and the third operation is receiving data from the BS and transmitting data to the BS.

A method for transmitting and receiving signals using multiple frequency band in a wireless communication system are provided, in which a BS determines whether an MS is to use a plurality of FAs, selects the plurality of FAs if it is determined that the MS is to use the plurality of FAs, transmits FA information about the selected FAs to the MS, and transmits and receives signals to and from the MS in the selected FAs.

摘要:
A method for controlling a sleep mode operation by a Mobile Station (MS) in a communication system. The MS includes transitioning to an awake state in a listening interval of the sleep mode; performing any one of a first operation, a second operation and a third operation in the awake state; and after any one operation is performed, transitioning to a sleep state upon detecting that there is no data to transmit to the BS and there is no data to be received from the BS. The first operation is a process of receiving data from the BS, the second operation is a process of transmitting data to the BS, and the third operation is a process of receiving data from the BS and receiving data from the BS.

A method for supporting a handover at a source Base Station (BS) in a wireless communication system is provided, in which a HandOver CoMmanD (HO-CMD) message is transmitted to a Mobile Station (MS). The HO-CMD message includes a Ranging CHannel (RCH) index of an RCH allocated to the MS by a target BS and a subframe index of the allocated RCH, and the RCH index of the allocated RCH does not overlap with indexes of other RCHs of the target BS.

A method for managing flow information of a mobile station by a target base station in a communication system is provided. The method includes receiving a ranging request message, which includes a flow identifier for each of flows between a serving base station and the mobile station and a change count indicating the number of times of an addition/change/deletion operation of a corresponding flow for each of flow identifiers, from the mobile station; and transmitting a ranging response message, which includes a validity indicator indicating whether the change count of each of the flow identifiers is valid or not, to the mobile station, wherein, when the validity indicator indicates that at least one change count among change counts for each of the flow identifiers is not valid, the ranging response message includes a list including the at least one change count that is not valid.

An apparatus and a method for transmitting and receiving an Automatic Repeat reQuest (ARQ) feedback message in a wireless communication system are provided. A method for receiving an ARQ feedback message at a transmitting unit in a wireless communication system includes allocating a fixed-size resource for transmitting an ARQ feedback message, to a receiving unit, the resource being an unsolicited bandwidth, and receiving an ARQ feedback message or a resource request message from the receiving unit over the fixed-size resource allocated.

摘要:
A method and an apparatus for reducing a handover delay in a broadband wireless communication system are provided. In a method for operating a terminal to reduce a handover delay in a broadband wireless communication system, a handover procedure is performed with a serving Base Station (BS) to obtain a dedicated ranging code and a Connection ID (CID). The dedicated ranging code is transmitted to one or more target BSs using the CID. Whether the dedicated ranging code is received is determined. Therefore, a handover delay and a chance of malfunction can be reduced.
