Abstract
A mobile station device transmits channel quality indicators for a plurality of system bands, wherein each of the plurality of system bands includes a plurality of subbands comprising a set of contiguous resource blocks, and wherein each of the channel quality indicators is derived to satisfy a condition assuming a subband of the plurality of subbands, and wherein the number of the resource blocks within the subband is based on a frequency bandwidth of a system band of the plurality of system bands and the system band includes the subband.
Claims6
A base station device configured and/or programmed to communicate with a mobile station device, the base station device comprising:
- notifying circuitry configured and/or programmed to notify the mobile station device of information indicating a frequency bandwidth of each of a plurality of system bands to be used for the mobile station device to communicate with the base station device;
- and
- reception circuitry configured and/or programmed to receive, from the mobile station, channel quality indicators for each of the plurality of system bands, wherein
- each of the plurality of system bands includes a plurality of subbands, each of the subbands comprising a set of contiguous resource blocks,
- each of the channel quality indicators is derived to satisfy a condition assuming a subband of the plurality of subbands,
- for each of the plurality of system bands, the natural number, N, of the resource blocks within the subband is based on the frequency bandwidth of the corresponding system band, and the corresponding system band includes the subband, and
- in a case that the total number of resource blocks within the corresponding system band is not a multiple of N, N applies to all of the plurality of subbands within the corresponding system band except for one subband, and the number of resource blocks within the one subband is less than N.
