Abstract: A method for managing beam alignment by a user equipment is provided. The method comprises receiving beam width information and base station location information from a base station, calculating a displacement of location of the UE based on location coordinates of the UE, measuring a change in a signal strength of the UE due to the displacement, and determining whether the UE is moving towards or away from the base station using at least one of the beam width information, base station location information, the displacement, and the measured change in the signal strength, determining whether a beam re-alignment is required based on the determination of the movement of UE, and transmitting a realignment request to the base station for a re-aligned beam width and a new transmission beam based on determining that the beam re-alignment is required.

Abstract: A method of dynamic memory management in a user equipment (UE) is provided. The method includes receiving, by the UE, transport block size (TBS) information, from a base station (BS), associated with a data packet to be transmitted by the BS to the UE; identifying, by the UE, a plurality of empty bins and a size of each of the plurality of empty bins in a memory of the UE; detecting, by the UE, a presence of one or more empty bins, among the plurality of empty bins in the memory, with a size of each of the one or more empty bins greater than the TBS of the data packet; and allocating, by the UE, a smallest size empty bin, with a size greater than the TBS of the data packet, among the one or more empty bins to the data packet.

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 a Long Term Evolution (LTE).The present disclosure provides a method and system for enabling discontinuous reception (DRX) over an unlicensed band in cellular networks. 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: Embodiments herein provide methods and systems for achieving D2D communications through unlicensed spectrum. The D2D-U operations can be achieved through multiple approaches. In the first approach, the devices can communicate with each other without any involvement of network. In the second approach, the network provides partial assistance to the devices such as allocating time and frequency resources for D2D-U communication. In the third approach, the network completely controls D2D-U operations between the devices. The embodiments include allocating time and frequency resources for transmission of PSBCH, PSDCH, PSCCH, and PSSCH. The allocations of the time and frequency resources meet regulatory requirements of minimum bandwidth utilization for unlicensed band operation. The embodiments include distributing power in narrow frequency sub-bands of D2D-U spectrum, in order to maximize transmission range of D2D-U communications.

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.
