1. A communication method comprising: generating resource assignment information including a plurality of bits that indicate activation/deactivation statuses of respective downlink component carriers, the downlink component carriers being secondary downlink component carriers added to a primary component carrier which is always activated, each downlink component carrier corresponding to one bit included in the plurality of bits, and the one bit indicating that a corresponding downlink component carrier is to be activated or deactivated, wherein when any one bit of the plurality of bits indicates that its corresponding downlink component carrier is to be activated, the plurality of bits jointly indicate the activation/deactivation statuses and a sounding reference signal (SRS) transmission request; transmitting the generated resource assignment information; and receiving a SRS that is transmitted, in response to the SRS transmission request, on an uplink component carrier linked to an activated downlink component carrier(s).
