Patent number: 7944893Abstract: A signal transmission method checks, when detecting an occurrence of a communication request, whether the communication request is a high speed communication (step S302). In the case of the high speed communication, it checks whether the number of current high speed communications (m) plus one is greater than the upper limit (mmax) of the high speed communication (step S312). If greater, it cancels the request as a call loss (S316), and sets to a variable a the ratio (h) of the rate of the high speed communication to that of a low speed communication. If the communication request is the low speed communication, it sets one to the variable a (step S304). It compares n plus a with nmax (step S306), where n is the total number of all the current communications, a is the value associated with the communication request, and nmax is the upper limit of the number of communications acceptable in a bandwidth, all of which are expressed in terms of the number of the low speed communications.Type: GrantFiled: December 11, 2008Date of Patent: May 17, 2011Assignee: NTT DoCoMo, Inc.Inventors: Shinji Uebayashi, Seizo Onoe, Minami Ishii, Takehiro Nakamura

Publication number: 20110092243Abstract: To control allocation of a portion of a shared channel to use for control information, a base station determines an amount of resource elements of the shared channel to use for the control information in place of traffic data. The base station sends, to a mobile station, an indication relating to an offset parameter, where the indication is provided to allow the mobile station to compute a value for the offset parameter such that the mobile station can determine the amount of the resource elements of the shared channel to allocate for the control information.Type: ApplicationFiled: June 30, 2009Publication date: April 21, 2011Applicant: NORTEL NETWORKS LIMITEDInventors: Lai-King Tee, Neng Wang, Yi Song

Publication number: 20110092242Abstract: The present invention provides a method, a radio base station (40) and a mobile terminal (50) for allocating resources in a telecommunications network, where communications between the radio base station (40) and the mobile terminal (50) take place over a plurality of carriers. The method comprises transmitting and receiving a resource allocation message comprising one or more bits. Each of the bits corresponds to a number of resource blocks, where the number is determined from the ratio of the aggregate bandwidth of the plurality of carriers divided by the bandwidth of the carrier over which the resource allocation message is sent.Type: ApplicationFiled: December 10, 2008Publication date: April 21, 2011Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Stefan Parkvall, Erik Dahlman, Ylva Jading, Bengt Lindoff

Publication number: 20110086652Abstract: A method and apparatus allocates a Physical Cell Identifier (PCID) in a wireless communication system by considering a PCID reuse factor. An allowable PCID list is acquired from a server. A set of candidate PCIDs is determined from the allowable PCID list according to PCID allocation conditions. A received signal strength of each cell using the determined set of candidate PCID is determined. At least one PCID is selected by using a PCID reuse factor and the received signal strength of each of the cells using the determined set of candidate PCIDs.Type: ApplicationFiled: October 7, 2010Publication date: April 14, 2011Applicants: SAMSUNG ELECTRONICS CO., LTD., INDUSTRY-UNIVERSITY COOPERATION FOUNDATION SOGANG UNIVERSITYInventors: Jung-Min So, Hee-Jung Byun, Bong-Jhin Shin, Ga-Hee Lee, Dae-Hyoung Hong, Mi-Sun Do, Hyon-Goo Kang

Patent number: 7924781Abstract: In a communication system, a method and an apparatus provide for efficient communications of data rate control information. A mobile station communicates a request on a data channel for reception of a data file on a traffic channel. In response to the request, a transmitter in mobile station starts communication of data rate control information on a data rate control channel. After concluding the delivery of a requested data file by a receiver in mobile station, transmitter ceases communication of data rate control information on data rate control channel from mobile station.Type: GrantFiled: August 29, 2006Date of Patent: April 12, 2011Assignee: QUALCOMM IncorporatedInventor: Yu-Cheun Jou

Patent number: 7925290Abstract: A system and method for providing high performance dispatch services for a push-to-talk (PTT) communication over a wireless communication network. When a wireless device is powered up, it registers with a server and then transitions to a paging state instead of an idle state. When the wireless device is ready to transmit PTT communications, it sends a message to the server and transitions to a transmission state when a confirmation is received from the server. Once in the transmission state, the wireless device is ready to transmit the PTT communications to the server.Type: GrantFiled: March 31, 2005Date of Patent: April 12, 2011Assignee: QUALCOMM IncorporatedInventors: Eric C. Rosen, Francesco Grilli, Harleen K. Gill

Patent number: 7925267Abstract: A method for transmitting to one cell a frame including broadcast channels in a cellular wireless communication system in which a base station supports a plurality of physical channels corresponding to the broadcast channels. The base station generates the frame and transmits the generated frame to a mobile station. The frame includes separate broadcast channels for the respective physical channels. A position, in the frame, of a first broadcast channel for a physical channel capable of supporting a mobile station having the worst channel state is fixed in all of transmission frames. The first broadcast channel includes positional information of the remaining broadcast channels except for the first broadcast channel. The mobile station detects only an address of a broadcast channel for a physical channel allocated thereto from the first broadcast channel among broadcast channels belonging to the frame.Type: GrantFiled: January 13, 2006Date of Patent: April 12, 2011Assignee: Samsung Electronics Co., LtdInventors: Young-Ho Jung, Jae-Hak Chung, Seung-Hoon Nam, Yung-Soo Kim, Sung-Hyun Cho

Publication number: 20110081932Abstract: The invention is a method and apparatus for signaling uplink control information in a mobile communication network using carrier aggregation. The signaling mechanism allows the transmission, on a single uplink component carrier, of control information associated with a downlink transmission on multiple aggregated downlink component carriers. Semi-statically reserved resources for the transmission of control information on the uplink component carrier may be dynamically shared by user terminals that are assigned multiple downlink component carriers for downlink transmissions. Implicit or explicit resource indication can be used in combination with dynamic resource indication.Type: ApplicationFiled: October 4, 2010Publication date: April 7, 2011Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: David Astely, Robert Baldemair, Dirk Gerstenberger, Daniel Larsson, Lars Lindbom, Stefan Parkvall
