  • Publication number: 20200022123
    Abstract: A mobile station (MS) communicates with a base station (BS) by a carrier aggregation using a plurality of downlink component carriers (DCCs). The MS receives on one or more activated DCCs. The MS receives using a PDCCH on one of activated DCCs, from the BS, first information including an information field for requesting a transmission of channel state information (CSI), the first information being used for scheduling of a PUSCH. The MS transmits using the PUSCH in a first subframe on an uplink component carrier, to the BS, first CSI for more than one activated DCCs. The MS transmits using the PUSCH in a second subframe on the uplink component carrier, to the BS, second CSI for only one activated downlink component carrier. The transmission of the second CSI is scheduled by the first information received using the PDCCH on the only one activated downlink component carrier.
