Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method and system for managing data transmission in a communication network is provided. During Data Resource Bearer (DRB) creation, network signals to a transmitting node, the data transfer requirement. The network uses a signaling parameter to indicate a large data transfer requirement. Based on the data transfer requirement information collected from the network, the transmitting node determines the type of data format that needs to be used for the data transmission. If the network signals large data transfer requirement, then the transmitting node selects a Subheader format in which the length field of the data format suits the large data transfer requirement. Further, data communication is initiated using the selected Subheader format.

Abstract: The present invention provides a method and system for performing Hybrid Automatic Repeat Request (HARQ) operation in an asymmetric multicarrier communication network environment. In one embodiment, a method includes receiving resource allocation information from a base station. The method also includes transmitting the HARQ packet to the base station in a transmit time interval (TTI) corresponding a first or second partition of an uplink allocation interval on a second carrier. The method further includes receiving HARQ feedback information corresponding to a previous HARQ packet transmission. Furthermore, the method includes determining a TTI in a subsequent uplink allocation interval based on the partition of the uplink allocation interval in which the HARQ packet is transmitted if the HARQ feedback information indicates negative acknowledgement. Moreover, the method includes transmitting the HARQ packet to the base station in the determined transmit time interval of the subsequent uplink allocation interval on the second carrier.

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.

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.
