Patent number: 7437175Abstract: Methods and apparatus for determining when uplink synchronization has been achieved when entering or adding a link in soft handover to a new node in a communication system. Transmit power control (TPC) commands from the new link are not included in a TPC command combination until an uplink synchronization detector determines that synchronization has been achieved. Since in many communication systems, a pattern of TPC commands is transmitted on the new downlink as long as the new node's uplink is not synchronized, the uplink synchronization detector can determine whether synchronization has been achieved by determining whether the TPC command pattern is present in the new downlink. In this way, the UL synchronization detector reduces the occurrence and magnitude of unwanted peaks and dips in uplink transmitted power.Type: GrantFiled: May 6, 2004Date of Patent: October 14, 2008Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Bengt Lindoff, Bo Bernhardsson

Patent number: 7428425Abstract: A criterion for biasing a binary decision requiring an unequal protection which utilizes a measured signal to interference ratio (SIR). The SIR may be derived from a determination of channel estimation. The SIR is compared against a threshold, the threshold being selected to bias the decision toward a NACK as opposed to an ACK determination. The technique is advantageous for providing biased binary decisions for high speed downlink packets (HSDP) but may be utilized for both uplink and downlink applications.Type: GrantFiled: February 19, 2003Date of Patent: September 23, 2008Assignee: InterDigital Technology CorporationInventors: Stephen G.

Publication number: 20080227406Abstract: Embodiments of the present invention extend the benefits of mobile transmit diversity to the initialization phase of communication with a base station over a random access channel. According to a method of the invention, the transmitter may attempt to initiate communication with a receiver by varying a transmit diversity parameter, for example, phase difference, in addition to or instead of varying power settings.Type: ApplicationFiled: March 5, 2008Publication date: September 18, 2008Inventors: Kenneth KLUDT, Sherwin J.

Publication number: 20080227476Abstract: A method for controlling power in a communication system. A base station allocats Channel Quality Information Channels to at least one mobile station, transmits the allocated Channel Quality Information Channel information, and transmits power control information to the mobile station to which the Channel Quality Information Channel is allocated. And a mobile station for receives Channel Quality Information Channel allocation information, receives power control information, and detects the power control information allocated to the mobile station by using the Channel Quality Information Channel allocation information.Type: ApplicationFiled: November 29, 2007Publication date: September 18, 2008Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jae-Hee CHO, Heon-Ki Chae, Soon-Young Yoon, In-Seok Hwang, June Moon

Publication number: 20080212528Abstract: The present invention relates to a radio network controller and a radio base station for prioritisation of signalling radio bearers (SRB) with regard to their content to achieve an efficient resource usage. The radio network controller can retrieve knowledge about the resource status in a Node B serving a certain user equipment and request this Node B to prioritize signalling radio bearers (SRB) carrying signalling information with regard to radio resource control that is of particular importance and intended to be efficiently forwarded to said user equipment. The Node B then prioritises such signalling radio bearers and schedules the prioritized signalling radio bearers with respect to their priorities using sufficient radio resources.Type: ApplicationFiled: July 10, 2006Publication date: September 4, 2008Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventors: Muhammad Kazmi, Henrik Enbuske

Patent number: 7418269Abstract: A wireless communications system has a plurality of uplink and downlink channels available for use. Channels are distributed among different operators who may plan their networks in a non-ideal manner. A terminal uses an uplink channel and a downlink channel selected from those available and performs a method to check whether it is causing interference to other users of the system. The method determines whether the terminal is transmitting at a power which may cause interference to an adjacent uplink channel. If so, the terminal determines which downlink channel is associated with the adjacent uplink channel and monitors that downlink channel. The terminal may then operate in a manner which will reduce interference.Type: GrantFiled: June 30, 2004Date of Patent: August 26, 2008Assignee: Nortel Networks LimitedInventor: Keith Russell Edwards

Patent number: RE40825Abstract: A method and an arrangement are provided for timing a change of diversity weights in a radio connection between a base station and a terminal. A response timing mode is selected from a number of predefined response timing modes. The terminal is informed about the selected response timing mode. An initiation is received from the terminal and it is responded to the initiation by changing certain diversity weights so that the exact moment of time for effecting the change is determined by the selected response timing mode.Type: GrantFiled: July 13, 2006Date of Patent: July 7, 2009Assignee: Nokia CorporationInventors: Hannu Hakkinen, Kari Pehkonen, Esa Malkamaki
