| 发明名称 | Method of generating channel quality indicator adaptively in downlink status and user equipment for the same | ||
| 摘要 | A method for generating a channel quality indicator (CQI) in a mobile communication system is presented. The method includes grouping a number of subcarriers to form at least one channel quality indicator subband for generating a channel quality indicator, and generating a channel quality indicator in each channel quality indicator subband, wherein a size of each channel quality indicator subband is dependent on a system bandwidth value and is an integer multiple of a downlink frequency resource unit size, wherein the downlink frequency resource unit size is prescribed according to the system bandwidth value. | ||

| 主权项 | 1. A method for transmitting channel quality information from a user equipment (UE) in a mobile communication system, the method comprising: generating, by the UE, a single UE-selected subband channel quality indicator (CQI) for only M subbands, wherein the M subbands are selected, by the UE, from an entire downlink system bandwidth including N subbands, and wherein M and N are integers, M is a number of subbands, 1≦M<N; transmitting, by the UE, the single UE-selected subband CQI; and transmitting a combinatorial index indicating positions of the M subbands, wherein a size of each of the M subbands is an integer multiple of a downlink resource block (RB) including a plurality of subcarriers, and the size of each of the M subbands is determined based on the entire downlink system bandwidth, wherein M is set to a higher value for a wider bandwidth of the entire downlink system bandwidth, wherein M is set to a lower value for a reduced bandwidth of the entire downlink system bandwidth, and wherein the single UE-selected subband CQI for the selected M subbands is transmitted when M is greater than 1. | ||
