Publication number: 20110305181Abstract: In a method and a device for controlling the output power in a Base Transceiver Station adapted to transmit signals over an air interface using a power amplifier for multiple earners, the power of signals to be transmitted in an upcoming transmission time slot are added and compared to at least one threshold value. If the threshold is exceeded the output power is reduced. By implementing a power reduction scheme as set out above the risk for peak power effects is minimized at the same time as the dimensioning may be aggressive. This is made possible because no power will be backed off unless really needed.Type: ApplicationFiled: September 11, 2009Publication date: December 15, 2011Applicant: TELEFONAKTIEBOALGET LM ERICSSON (PUBL)Inventors: Sofia Svedevall, Benny Lennartson, Torsten Lind

Publication number: 20100081427Abstract: The invention discloses a method (700) for finding differences in path loss between a plurality of RF paths between a first (120, 130) and a second (120, 130) transceiver in a wireless communications system (100). During defined 5 intervals of time (SACCH1-SACCH4), only one RF path is used to transmit from one of said transceivers to the other of said transceivers, and the receiving transceiver measures the strength of the signal received during at least a number of said intervals, thus making it possible to compare signal strength and thereby path loss between different RF paths, which in turn 10 makes it possible to find imperfections in one or more of said RF paths.Type: ApplicationFiled: March 26, 2007Publication date: April 1, 2010Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Benny Lennartson, Lars Boncz

Publication number: 20100062771Abstract: In a mobile station for use in a cellular radio system, the mobile station is adapted to increase radio measurements relating to the currently best cell at times when the user is preparing to set up a call in order to increase the likelihood that a mobile station is camping in the correct cell when setting up a call. This is obtained by adding a third mode to the already existing idle and active modes. The additional mode provides for an increased amount of idle mode measurements compared to the conventional idle mode.Type: ApplicationFiled: March 8, 2007Publication date: March 11, 2010Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Krister Sundberg, Benny Lennartson
