CPC H04B 7/0456 (2013.01) [H04B 7/0413 (2013.01); H04B 7/0452 (2013.01); H04B 7/0628 (2013.01); H04B 7/0671 (2013.01)] | 6 Claims |
1. An integrated circuit for a terminal apparatus, the integrated circuit comprising:
at least one input which, in operation, receives an input; and
circuitry coupled to the at least one input, the circuitry, in operation, controls
transmitting capability information indicative of capabilities of the terminal apparatus, the transmitted capability information including at least one main capability field and a plurality of dependent capability fields, each of the plurality of dependent capability fields being associated with one of the at least one main capability field, wherein the at least one main capability field includes a multi-stream capability field for indicating whether multi-stream is supported or not, and the plurality of dependent capability fields include a precoding field for indicating a precoding method that is supported by the terminal apparatus;
receiving N multiplexed signal streams (N is an integer equal to 2 or greater) that are generated based on the multi-stream capability field in the transmitted capability information by a base station apparatus that receives the transmitted capability information; and
performing signal processing on the N multiplexed signal streams based on the at least one main capability field and the plurality of dependent capability fields in the transmitted capability information,
wherein the N multiplexed signal streams are generated by the base station apparatus by generating a transmission stream based on the at least one main capability field and the plurality of dependent capability fields in the transmitted capability information and performing spatial multiplexing on transmission streams.
