Patent number: 10149316Abstract: The present invention relates to granting time intervals for transmitting a control signal burst and, more particularly, to methods and devices for granting Dedicated Physical Control Channel (DPCCH) bursts for Wideband Code Division Multiple Access (WCDMA). A base station determines whether a predetermined condition for transmitting a grant signal is satisfied and, if so, determines a schedule for receiving a control signal burst from a mobile device and transmits, in accordance with the determined schedule, the grant signal to at least said mobile device. Correspondingly, a mobile device transmits a report to a base station causing it to determine, in accordance with the report, a schedule for transmitting a control signal burst. Then the mobile device receives grant signals in accordance with the determined schedule and transmits a control signal burst in accordance with the grant signal.Type: GrantFiled: September 26, 2014Date of Patent: December 4, 2018Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Billy Hogan, Cagatay Konuskan, Gerardo Agni Medina Acosta, Stéphane Tessier

Patent number: 9961644Abstract: The present application discloses methods and apparatus for modifying a normal link adaptation process of a wireless device (200). The normal link adaptation process may be used to compensate for a fast fading dip detected by a base station (100). The present application teaches that the normal fast fading compensation may cause inter-cell interference and degrade system performance. The present application discloses imposing a fast fading restriction or limitation on the normal fast fading compensation can reduce inter-cell interference, improve system capacity, and extends the battery life of the wireless device.Type: GrantFiled: January 20, 2014Date of Patent: May 1, 2018Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Patrik Karlsson, Billy Hogan, Waikwok Kwong

Patent number: 9788283Abstract: The present disclosure relates to a method and user equipment, UE, in a wireless communication network of performing power scaling on uplink transmission to a receiving radio access node, RAN. In particular, the disclosure relates to a method and user equipment for power scaling on uplink transmissions on a multi-radio access bearer, multi-RAB, wherein a Dedicated Physical Data Channel, DPDCH, and enhanced Data Channels, E-DCHs are configured for uplink transmission from the UE to the receiving RAN. The method comprises determining a total UE transmit power exceeding a predetermined maximum power limit value. The total UE transmit power is reduced to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. When a predetermined minimum E-DPDCH gain factor, ‘smallest quantised ?ed,k value’, is reached for all E-DPDCH gain factors ?ed,k, and DTX is applied for all E-DPDCHs, the method comprises applying DTX on E-DPCCH.Type: GrantFiled: January 7, 2014Date of Patent: October 10, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Cagatay Konuskan, Billy Hogan, Andreas Andersson
