    摘要: A method and apparatus for transmitting/receiving a Channel Quality Indicator (CQI) in a communication system are provided. It is determined whether there is any uplink data to transmit, when a CQI transmission time arrives according to a predetermined CQI transmission period. If there is uplink data to transmit, a part of the uplink data is punctured to insert the CQI therein, and the inserted CQI is multiplexed with the uplink data before transmission. It is determined whether there is any uplink data to receive from a terminal, when a CQI reception time arrives according to a predetermined CQI transmission period. If there is uplink data to receive, the uplink data is received from the terminal, and the received uplink data is demultiplexed to extract the CQI.

    摘要: A method and system for indexing physical channels in an OFDMA system where one OFDM symbol includes a plurality of subcarriers and one TTI includes a plurality of OFDM symbols are provided. A total number of subcarriers per OFDM symbol are divided into N groups. A kth group is selected from the N groups in each OFDM symbol of a TTI, and a physical channel corresponding to a set of subcarriers indexed with predetermined values, included in the kth groups of the TTI is indexed with an ordered pair (N, k).

    摘要: Methods and apparatus are provided for constructing scheduling assignments for transmission, by a User Equipment (UE), of data signals over a single contiguous bandwidth and multiple non-contiguous clusters of contiguous bandwidth. The scheduling assignments for each transmission structure are designed to always result into the same maximum number of decoding operations the UE needs to perform to receive the scheduling assignments. The data signal transmission over the single contiguous bandwidth can be with or without frequency hopping and the data signal transmission over the multiple non-contiguous clusters of contiguous bandwidth may always be without frequency hopping.

    摘要: A transmission/reception method and apparatus in an Orthogonal Frequency Division Multiplexing (OFDM)-based wireless communication system are provided, in which a data transmitter adaptively selects a multiplexing scheme according to a code rate of the transmission packet or an effective SNR of a wireless channel for a corresponding terminal, when transmitting a packet data channel. The adaptive multiplexing scheme is equal in concept to a scheme of adaptively implementing unitary precoding. The unitary precoded multiplexing includes Orthogonal Frequency code Domain Multiplexing (OFCDM), Fast Fourier Transform-Spread-OFDM (FFT-S-OFDM), Fast Frequency Hopping-OFDM (FFH-OFDM), and the like. The method and apparatus adaptively selects the multiplexing scheme and transmits/receives data using the selected multiplexing scheme, thereby improving reception performance of the packet data.
