Abstract
Official abstract text for this publication.
A communication apparatus and a communication method capable of suppressing an increase of bits used for a request to send a reference signal and flexibly setting a resource used for sending a reference signal. In a base station, a transmission processing unit transmits, in one of a plurality of formats, control information containing a request to send a sounding reference signal (A-SRS), and a reception processing unit receives the transmitted A-SRS using the resource specified by the format of the transmitted control information. Then, the plurality of formats is associated with each different SRS resource by a setting unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A communication apparatus comprising: a transmitter, which, in operation, transmits downlink control information including a transmission request of a sounding reference signal (SRS) using one downlink control information format (DCI format) among a plurality of DCI formats, wherein each DCI format corresponds to at least one set of SRS parameters, the at least one set of SRS parameters for one DCI format is different from the at least one set of SRS…
