Claim of US Patent No. 10,342,039

1. An integrated circuit to control a process, the process comprising:in response to receiving downlink assignment information in a first control channel on a Control Channel Element (CCE) of a Physical Downlink Control Channel (PDCCH) region, wherein the downlink assignment information indicates a resource in a primary cell,
receiving first downlink data on the resource in the primary cell indicated by the downlink assignment information,
receiving second downlink data in a secondary cell,
generating response signals for the first downlink data and the second downlink data, and
transmitting the response signals on one of a first set of uplink resources including a first resource, the first resource determined by a first method, wherein the first method determines the first resource based on an index of the CCE of the PDCCH region on which the downlink assignment information is received; and
in response to receiving the downlink assignment information in a second control channel different from the first control channel,
receiving the first downlink data on the resource in the primary cell indicated by the downlink assignment information,
receiving the second downlink data in the secondary cell,
generating response signals for the first downlink data and the second downlink data, and
transmitting the response signals on one of a second set of uplink resources including a second resource, the second resource determined by a second method different from the first method.
