Abstract: 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.

Abstract: 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.

Abstract: A method of allocating resources in a wireless communication system includes dividing an available frequency band on a logical plane into a distributed zone and a localized zone, dividing the distributed zone into a plurality of subparts in time domain, and dividing the distributed zone and the localized zone into a distributed zone and a localized zone on a physical plane. The plurality of subparts included in one distributed zone on the logical plane is mapped to a different distributed zone on the physical plane.

Abstract: 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.

Abstract: A method of performing a cell reselection procedure in a wireless communication system includes evaluating priorities of a serving cell and neighbor cells, each of which use different frequency bands, performing inter-frequency measurement on a neighbor cell which has a higher priority than the serving cell, performing the inter-frequency measurement on a neighbor cell which has an equal or lower priority than the serving cell, when a signal characteristic of the serving cell is less than a threshold, and performing cell reselection according to the priorities.

Abstract: A data retransmission method using hybrid automatic repeat request (HARQ) includes transmitting a data block, receiving a retransmission request signal for the data block, generating a retransmission block by performing swapping or inversion between bits constituting the data block according to the retransmission request signal, and transmitting the retransmission block.

Abstract: 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.

The number of resource elements allocated for the virtual resource block is constantly maintained.

Abstract: A method of reporting a channel state for a plurality of bands includes transmitting channel quality indicators (CQIs) for the respective bands, and transmitting CQI variation information, wherein the CQI variation information comprises CQI up/down information indicating whether the CQIs of the respective bands collectively increase or decrease and a CQI variation indicating a collective variation of the CQIs of the respective bands. Accordingly, waste of resources consumed for the CQIs can be reduced.

Abstract: A method for configurating a basic signal allocation unit and a method of transmitting signals using the configurated basic signal allocation unit are disclosed. In particular, a basic frequency domain signal allocation unit is configurated by considering at least one selected from the group consisting of a signaling overhead, a size of a coherent bandwidth and a number of divisors among specific numbers and an OFDM symbol number corresponding to a multiple of a subframe unit, each of the specific numbers multiplied to a predetermined subcarrier spacing to enable a result value of the multiplication to have a difference smaller than a prescribed threshold from a divisor of a system bandwidth. And, a time domain unit is configurated by 1-subframe unit. Accordingly, signaling overhead can be efficiently reduced.
