Abstract: Method and system for managing hidden node problem in a communication network. A receiving node in the system, upon receiving a data transmission request from at least one transmitting node, dynamically checks status of the channel between the transmitting node and the receiving node. If the channel is found to be clear for transmission, then the receiving node sends a message that indicates that the channel is clear, to the transmitting node, and the transmitting node starts transmitting the data. Upon receiving a message from the receiving node that the channel is not clear for transmission, then the transmitting node waits for a particular time period and attempts the connection again.

Abstract: Hybrid Automatic Repeat Request (HARQ) operation in an asymmetric multicarrier communication network environment is performed, in one embodiment, by receiving resource allocation information from a base station, 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, and receiving HARQ feedback information corresponding to a previous HARQ packet transmission. A TTI in a subsequent uplink allocation interval is determined based on the partition of the uplink allocation interval in which the HARQ packet is transmitted if the HARQ feedback information indicates negative acknowledgement. The HARQ packet is transmitted to the base station in the determined transmit time interval of the subsequent uplink allocation interval on the second carrier.

Abstract: A method and system for acquiring mmWave carrier in a wireless communication network is disclosed. In one embodiment, an MS acquires a low frequency carrier and then acquires the high frequency carrier. Since the low frequency carrier and the high frequency carrier are transmitted by same BS, the BS provides assistance information on the acquired low frequency carrier to the MS to acquire a synchronization signal which is transmitted on a high frequency carrier using beamforming. The assistance information includes synchronization signal beam time slots, synchronization signal beams which the MS needs to search, beam ID and so on. Based on the assistance information, the MS monitors the high frequency carrier to search and acquire the synchronization beam signal transmitted on the high frequency carrier. The MS determines the beam ID of the received synchronization beam signal and reports to the BS on the low frequency carrier.

Abstract: Embodiments herein provide a method for determining PO by UEs in an eDRX cycle. The method includes determining PHs in the eDRX cycle based on estimated values of UE_ID_H and number of hyper-frames in the eDRX cycle. The method includes determining a first radio frame of PTW based on a determined value of NPTW and ieDRX. The method includes determining a last radio frame of PTW based on the first radio frame and length of the PTW. The method includes determining PFs in the PTW. The determination of PFs is based on the UE_ID. The method includes determining the POs, in each of the determined PFs, based on an index associated with each of the POs. The index associated with each PO is computed based on the UE_ID, number of frames available for paging in a DRX cycle, and number of sub-frames available for paging in each PF.

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.
