摘要： A first carrier of a carrier aggregation system has a downlink control region DCR which is selectively enabled and disabled. For the case the DCR of the first carrier is disabled, a DCR of a second carrier is used to cross-schedule a user equipment for radio resources on the first carrier. In various embodiments: the DCR of the first carrier lies within an unlicensed radio frequency band; the DCR of the first carrier is disabled by signaling which reduces to zero a number of symbols reserved for the DCR and is enabled by signaling which increases from zero a number of symbols reserved for the DCR; the signaling is downlink and group-based to a plurality of user equipments. The group-based signaling may be a broadcast system information block or a group RNTI, either of which give frequency information of the DCR and an enabled/disabled status indication.

摘要： Methods, apparatus and computer program products are provided for rebalancing the sizes of downlink (DL) association sets for component carriers having different time division duplex subframe configurations. A method is provided that includes determining DL subframes that are included in a DL association set for each of a plurality of component carriers. In an instance in which the number of acknowledgement (ACK)/negative acknowledgement (NACK) bits corresponding to the DL subframes included in the DL association sets for respective component carriers differ by at least a predetermined amount, the method modifies the number of ACK/NACK bits corresponding to the DL subframes that are included in the DL association sets for each of the respective component carriers. The method may also cause transmission of the ACK/NACK bits in accordance with the DL association sets, as modified, via the respective component carriers. Corresponding apparatus and computer program products are also provided.
