摘要:
A method for transmitting a voice over Internet protocol (VoIP) packet includes allocating a radio resource for VoIP packet transmission to a user, transitioning a VoIP service from a talk period, in which the VoIP packet is transmitted using the radio resource, to a silence period in which the VoIP packet is not transmitted, releasing the radio resource during the silence period, and transitioning the VoIP service to the talk period by reallocating the radio resource. Limited radio resources can be further effectively used.

A method of transmitting an interference information signal in a wireless communication system is provided. The method includes receiving a neighbor sounding signal from a mobile station (MS) in a neighbor cell, obtaining an interference information signal based on the neighbor sounding signal and transmitting the interference information signal to a neighbor base station (BS), the neighbor BS which is a BS in the neighbor cell.

A method of transmitting data is provided. The method includes generating a frame, the frame comprising a data burst, a submap and a map wherein the submap indicates a resource allocation state of the data burst, and the map indicates a differential adaptive modulation and coding (AMC) level for the submap, and transmitting data using the frame, wherein the differential AMC level is information on change in an AMC level applied to the submap comparing with other submap in a different frame. High-speed data transmission is realized and limited radio resources can be more efficiently used.

A method of data transmission using HARQ is provided. The method includes transmitting an uplink data, receiving an ACK/NACK signal for the uplink data, keeping the uplink data in a HARQ buffer when the ACK/NACK signal is an ACK signal, and retransmitting the uplink data when an uplink scheduling information for retransmission of the uplink data is received. In the present invention, a transmission error in an ACK/NACK signal is promptly detected, and thus data can be transmitted at a high speed.

A method for saving power in a multi-carrier wideband wireless access system is provided. A method for saving the power of a receiver in a multi-carrier wireless communication system includes acquiring multi-carrier information from a transmitter on a primary carrier, entering one or more secondary carriers satisfying a predetermined power saving mode entry condition out of one or more secondary carriers included in the multi-carrier information into a power saving mode, and receiving data during a listening interval according to the power saving mode on the one or more secondary carriers entering the power saving mode. The multi-carrier information includes at least one of information about a plurality of available carriers, information indicating the primary carrier and the one or more secondary carriers out of the plurality of available carriers, and information about the power saving mode entry condition of the one or more secondary carriers.

Provided are a method and apparatus for allocating resources for enhanced multicast broadcast service (E-MBS) data in a wireless communication system. A base station divides a frequency region into at least one frequency partition and allocates subbands of KSB,E-MBS number as the resources for the E-MBS data in the frequency partition. One sub-band includes sub-band logical resource units (SLRUs) of N1 number and the SLRUs of N1 number have continuous indexes among a plurality of physical resource units (PRUs) included in the frequency partition and are the PRUs to be allocated to contiguous resource units (CRUs).

New multiplexing UL structures for supporting legacy system are provided. A 16m system of diversity mode can be multiplexed with 16e system in PUSC mode in FDM manner with the same tiles/permutation rules. A 16m system can be multiplexed with 16e system in AMC mode in FDM and/or TDM manner. The time length of multiplexed 16e PUSC packets and/or 16m packets can be extended to more than two sub-frames for UL coverage. A PRU for 16m system may consists of 16 sub-carriers by 6 OFDMA symbols, 18 sub-carriers by 6 OFDMA symbols, or 20 sub-carriers by 6 OFDMA symbols when FDM is used.
