Abstract: A method and a system for signaling and processing control information in a cloud cell environment are provided. According to an embodiment, in a cloud cell, a master Base Station (BS) coordinates with other BSs to determine resources available for use on communication links between a mobile station in the cloud cell and one or all the BSs during a scheduling interval. Based on the resources available, the master BS allocates cumulative resources associated with the BSs to the mobile station for the scheduling interval. Then, the master BS transmits resource allocation control information indicating the allocated cumulative resources to the mobile station over a communication link between the master BS and the mobile station. Upon receiving the resource allocation control information, the mobile station decodes the information and receives data packets from each of the BSs during the scheduling interval according to the decoded resource allocation control information.

Abstract: The present invention provides a method and apparatus for performing an uplink Hybrid Automatic Repeat Request (HARQ) operation in an asymmetric multicarrier communication network environment. In one embodiment, a method includes transmitting a HARQ packet to a base station in a transmit time interval of one of a plurality of partitions of an uplink allocation interval on a first carrier by a mobile station. Then, the method includes determining a partition of the uplink allocation interval in which the HARQ packet is transmitted, and determining a HARQ feedback region in the subsequent downlink subframe corresponding to the determined partition. The method further includes receiving HARQ feedback information in the determined HARQ feedback region in the subsequent downlink subframe on a second carrier from the base station.

Abstract: A method and system signal resource allocation information in an asymmetric multicarrier communication network. A MS communicates with a BS using asymmetric carriers consisting of at least one low frequency carrier (e.g., primary carriers) in a cellular band and at least one high frequency carrier (e.g., secondary carriers) in a millimeter Wave band. In one embodiment, the BS allocates resources for one or more transmit time intervals in at least one of DL allocation interval of a secondary DL carrier and UL allocation interval of a secondary UL carrier for the MS, where the DL allocation interval spans one or more subframes of the secondary DL carrier and the UL allocation interval spans one or more subframes of the secondary UL carrier. The BS then transmits information regarding the allocated resources to the MS in a Packet Data Control Channel region of a subframe of the primary DL carrier.
