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.

In one embodiment, the method comprises of monitoring, by a user equipment (UE), an unlicensed channel at a pre-configured on period of a DRX cycle, wherein the UE wakes up during a DRX on period and sleeps during DRX off period, receiving an indication of extension of the DRX on period from an associated evolved node B (eNB) when the associated eNB is unable to acquire an unlicensed channel during a DRX on period of the licensed channel and continuously monitoring the unlicensed band for the extended DRX on period. The time period for extension of the DRX on period of the unlicensed channel is selected from a set of pre-specified extension values. The present disclosure further enables the UE to terminate monitoring of the DRX on period of the unlicensed channel upon receiving a stop monitoring indication from the associated eNB.

Abstract: A method of enabling cell acquisition in a wireless communication includes determining, by a first base station, a Mobile Station (MS) located at a granularity of a first frequency carrier cell sector level, identifying at least one second base station within the first frequency carrier cell sector level, transmitting a second frequency carrier cell search command to the MS and identifying, by the MS, the second frequency carrier cell based on one or more parameters defined in the search command. The first frequency carrier cell enables the MS to search for the second frequency carrier cell by providing a predefined number of synchronization slots to be monitored based on the location information of the MS.
