Patent number: 8694044Abstract: A first communication device and a method in a node serving a first cell of a first frequency for controlling transmission power of a user equipment in the first cell, comprising receiving data relating to a second cell of the first frequency from the user equipment and determining to power regulate the user equipment. Determining to power regulate the user equipment is based on determining that the second cell is a cell to which a soft handover cannot be performed and determining that the user equipment is within a range of a cell border of the first cell. That being the case, the method further comprises transmitting a control message to the user equipment to control the transmission power of the user equipment.Type: GrantFiled: August 22, 2008Date of Patent: April 8, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Kimmo Hiltunen, Tomas Nylander, Håkan Olofsson, Jari Vikberg

Patent number: 8155065Abstract: The present invention relates to methods and arrangements for interference reduction for bursty or intermitted transmissions. DPCCH gating with regular on/off-gating patterns can create waveforms that can interfere with non-UMTS audio equipments, e.g. hearing aids. The present invention relates to modifying the transmission instants of data packets in such a way such interference can be significantly reduced. This is achieved by introducing a randomization mechanism into the mapping function of data packets onto the HARQ processes, which in turn are mapped onto predefined transmission occasions (sub-frames). This results in a non-periodic transmission pattern while maintaining user data transmission requirements.Type: GrantFiled: February 9, 2007Date of Patent: April 10, 2012Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Dirk Gerstenberger, Hakan Olofsson, Johan Bergman
