摘要:
A synchronous retransmission method in a mobile communication system supporting a multicast service wherein one response channel is assigned on a multicast service-by-multicast service basis, and a response signal is transmitted through the response channel only when at least one mobile terminal fails in decoding for a packet transmitted by the multicast service. Accordingly, the response signal is rapidly transferred to the packet transmitted by the multicast service, and overhead from to the response channel can be reduced.
摘要:
A method of compressing uplink control information in a wireless communication system where an MSS scans neighbor BSs upon request from a serving BS and transmits neighbor BS information to the serving BS. In the method, the serving BS broadcasts a neighbor advertisement message including the BS ID of at least one neighbor BS about which the serving BS wants to acquire information, and the BS ID of the at least one neighbor BS. The MSS then scans a channel from the at least one neighbor BS and transmits a scanning result along with a BS index of the at least one neighbor BS to the serving BS.

A method of scheduling uplink resources in a wireless communication system supporting VoIP service is provided. A BS allocates an identical amount of the resource continuously until an uplink data rate is changed by an SS's request for a data rate change. When the data rate is changed, the SS reports this event to the BS so that the BS allocates an amount of resource corresponding to the requested data rate.

A system and method for transmitting resource allocation information in a wireless communication system is provided. A transmitter transmits resource allocation information mapped to a current time interval in a first region to a receiver, and transmits resource allocation information mapped to a next time interval in a second region. When receiving the resource allocation information of the second region, the receiver notifies the transmitter whether the resource allocation information has been received. The transmitter receives notification that the resource allocation information of the second region has been received and transmits resource allocation information mapped to a subsequent time interval in the second region.
摘要:
A method is provided for transmitting/receiving data in a communication system. The method includes allocating, by a Base Station (BS), bands unused in a band Adaptive-Modulation-and-Coding (band AMC) scheme to Mobile Stations (MSs) of a diversity scheme, and transmitting data by adaptively using the band AMC scheme and the diversity scheme; and identifying, by an MS, resources allocated to the MS, and transmitting data by using either the band AMC scheme or the diversity scheme according to a result of the identifying.

Provided is an apparatus and method for transmitting/receiving signals in a communication system. A base station allocates a quasi-dedicated control channel (QDCCH) to a first mobile station (MS), and allocates the QDCCH allocated to the first MS, to a second MS for a preset time. An MS receives a QDCCH allocated from the base station. If there is data to transmit to the base station, the MS determines whether the QDCCH is allocated to another MS different from the MS. If it is determined that the QDCCH is allocated to the MS itself, the MS transmits the data to the base station over the QDCCH.
摘要:
A method of reporting channel state information by a Mobile Station (MS) in a mobile communication system is disclosed. The method includes measuring a state of a downlink channel for the entire frequency band, determining a first Modulation and Coding Scheme (MCS) level corresponding to the measured channel state, and reporting the determined MCS level to a Base Station (BS).
