Claim Text:
1. A method implemented by a base station of receiving control information from a user terminal, the method comprising: scheduling downlink transmissions to a first user terminal on a single downlink component carrier associated with a primary cell and a second user terminal on multiple downlink component carriers including the single downlink component carrier associated with the primary cell; receiving control information associated with the downlink transmissions to the first user terminal on a first set of radio resources on an uplink component carrier associated with the primary cell, wherein the first set of radio resources is reserved for user terminals scheduled to receive downlink transmissions on the single downlink component carrier associated with the primary cell; receiving control information associated with the downlink transmissions to the second user terminal on a second set of radio resources on the uplink component carrier associated with the primary cell, wherein the second set of radio resources is reserved for user terminals scheduled to receive downlink transmissions on the multiple downlink component carriers and the second set of resources are additional resources as compared to the first set of resources; and transmitting, on the single downlink component carrier, an indication to assign radio resources in the second set of radio resources when the second user terminal is scheduled to receive the downlink transmissions on the multiple downlink component carriers.
