Patent number: 10588037Abstract: In a wireless communication device, a subset of available carriers is maintained as monitored carriers for performing measurements and the set of monitored carriers is replenished from only a subset of available carriers. Consequently, the wireless communication device does not have to measure a large number of carriers when looking for optimal radio network coverage. At the same time the method ensures that there is always an available “bucket” of monitored carriers that may be used for signal measurement. This means that the wireless communication device does not have to use a lot of processing resources (and thereby battery power) while still ensuring stable radio contact with the radio network or networks.Type: GrantFiled: July 9, 2014Date of Patent: March 10, 2020Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (publ)Inventors: Ali Nader, Joakim Axmon
