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: 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: A method which allows an evolved node B (eNB) to perform multi-subframe scheduling in enhanced license assisted access (eLAA) is provided. The eNB determining the subframes in a maximum channel occupancy time (MCOT) within which uplink transmission is performed. The eNB schedules resources for uplink transmission by user equipments (UEs) within the determined subframes. The UEs receive index values associated with a first subframe and a last subframe, in the determined subframes from the eNB. The first subframe and last subframe may be within a single, or multiple MCOTs. The UEs perform uplink transmission between the first subframe and the last subframe. The method allows forming a group with the plurality of UEs. A group identity, broadcast by the eNB, is received by the UEs. The method allows scheduling beams for performing uplink transmission by the UEs in 5th generation (5G) systems and scheduling multiple UEs while accounting spectral emissions.
