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.
