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: 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: An example security processing method includes receiving data packets at a packet data convergence protocol (PDCP) layer from an upper layer and parsing header information of each of the data packets to determine a length of each of the plurality of headers within the corresponding header information and whether a security header is present or absent in the corresponding data packets. The method further includes identifying corresponding header information of the data packets in which the security header is present based on the determination. The method further includes encrypting, based on the determined header lengths, only each of the plurality of headers of the identified corresponding header information in which the security header is present, and thereafter transmitting the one or more data packets to a lower layer after adding information regarding each of the encrypted headers along with their encryption length into a PDCP header.

Abstract: Embodiments of the disclosure provide a method for scheduling shared physical resource blocks (PRBs) by a user equipment (UE) in a wireless network and minimizing/reducing contention on the shared PRBs. The method includes: receiving PRBs from a network device, where the PRBs are shared among multiple UEs in the wireless network; detecting data at the UE for transmission; determining a modulation and coding scheme (MCS), a number of PRBs, and a size of a transport block required for data transmission in response to detecting the data; self-scheduling the shared PRBs based on at least one of the determined MCS, the number of PRBs, and the size of the transport block; and sending the data based on the self-scheduling along with self-scheduling information to the network device.
