Patent number: 11419071Abstract: Adopting a frequency multiplication scheme allows a network node to expand the number of transmit beams transmitted by it within a defined time interval, and allows the network node to transmit a greater number of synchronization signals on a per beam basis within the defined time interval. By way of example, the network node may operate in compliance with standardized restrictions regarding the timeframe during which it must transmit some base number of beam-based synchronization signals, while using a frequency multiplexing scheme to transmit additional beams within the same timeframe. Among the various advantages flowing from these operations, the ability to transmit more beams within the same timeframe allows the network node to tailor the beam shape and directions for broader coverage or enhanced range.Type: GrantFiled: October 17, 2017Date of Patent: August 16, 2022Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Magnus Åström, Fredrik Nordström
