Patent number: 7881257Abstract: A control method allocates to a base station, at a control member of the base station, a list of channels shared by several terminals containing several sets of shared channels. For a communication session between the base station and a specific terminal, the method indicates to the terminal the list of shared channels allocated to the base station. At the base station, the method selects for the terminal one of the sets of shared channels, and independently of the control member, indicates the selected set to the terminal via a dedicated channel.Type: GrantFiled: January 3, 2003Date of Patent: February 1, 2011Assignee: Alcatel LucentInventors: Denis Fauconnier, Sarah Boumendil, Evelyne Le Strat

Patent number: 7852811Abstract: In a collaborative, multiple input, multiple output wireless communication system, a transmitting device transmits a peak-limited pilot signal to a receiving device. The receiving device independently synthesizes the same pilot signal transmitted by the transmitting device. The synthesis process involves precoding the pilot signal and peak limiting the precoded pilot signal. The receiving device receives a signal r that represents the product of (i) a channel matrix H between the transmitting device and the receiving device and (ii) the peak-limited pilot signal yp(n)? plus noise ?, i.e. r=Hyp(n)?+?. The synthesized, peak-limited pilot signal can then be used by a channel estimator to determine an estimated channel matrix ?. Thus, the estimated channel matrix ? represents a closer estimate of the channel matrix H than conventional channel estimation processes and, thus, can provide better corresponding performance than conventional MIMO wireless communication systems.Type: GrantFiled: February 3, 2006Date of Patent: December 14, 2010Assignee: Freescale Semiconductor, Inc.Inventor: James W.

Patent number: 7831217Abstract: An external speaker/microphone apparatus for a radio transceiver includes a speaker, a microphone, a push-to-talk switch, and an emergency switch. The apparatus further includes an encoder module operatively coupled to the push-to-talk switch and the emergency switch and configured to generate a digital identification each time the push-to-talk switch is pressed, and a digital emergency signal and digital identification when the emergency switch is pressed. The apparatus also includes a connector configured to operatively couple audio to the speaker from the transceiver, a combination audio signal from the microphone and the encoder module to the transceiver. The connector is further configured to operatively couple the push-to-talk switch and the emergency switch to the transceiver so that the transceiver is switched to a transmit mode when either the push-to-talk switch or the emergency switch is pressed.Type: GrantFiled: October 10, 2007Date of Patent: November 9, 2010Assignee: Pine Valley Investments, Inc.Inventors: Bruno Yurman, Eric Matthew Jamerson, Joshua Burke Tredway, Gregory Paul Farmer

Patent number: 7826403Abstract: When no messages exist which must be notified to a mobile transmitting/receiving apparatus (102), a carrier signal of non-modulation is outputted in an area of control information of transport data having a frame structure. As a specific example, an FSK modulator (16) causes a carrier signal of non-modulation to be outputted by a transmitting circuit (17) from a line control apparatus (101) in correspondence with the area for control information in which non-modulation data is set by a frame data processing unit (15), while causing a modulated wave signal as four-level FSK modulated to be outputted in the areas other than the non-modulation data area. When non-modulation data is set in the area for control information, function channel identification information in the same frame is set as non-modulation identification data, thereby allowing any unstable operation in the mobile transmitting/receiving apparatus (102) on the receiving side to be avoided.Type: GrantFiled: September 16, 2005Date of Patent: November 2, 2010Assignee: Kabushiki Kaisha KenwoodInventor: Masaru Taniguchi

Patent number: 7813373Abstract: In a network comprising a source, a destination, and intermediate nodes along a route between the source and the destination, techniques are provided for allocating one or more time slots to transmit a particular data stream along the route based on the QoS requirements to transmit the particular data stream. In one implementation, a Scout Request message (SRM) is sent from the source to the destination to allocate time slots along the route to transmit a particular data stream to the destination. The SRM can include QoS requirements to transmit the particular data stream. Each intermediate node along the route can allocate one or more time slots to transmit the particular data stream based on the QoS requirements needed to transmit the particular data stream along the route.Type: GrantFiled: May 25, 2006Date of Patent: October 12, 2010Assignee: Motorola, Inc.Inventors: Avinash Joshi, Manish Shukla

Patent number: 7792935Abstract: An IP-based group communication feature in a mobile communication network is based on the pre-established logical connections established between a gateway node (GGSN) and members of a group in the mobile communication network. No separate call establishment procedures using VoIP signaling are used for connecting a user equipment (UE) logically to group(s), but the procedure is preferably based on the normal logical connection establishment signaling (e.g. PDP context creation) as used for data service. The UE implements a host supporting the IP multicasting, and the next IP layer peer for the UE host is located in the gateway node. The gateway node provides an IP interface towards an external multicast router so that the UE host looks like a normal IP host supporting IP multicasting. The IP-based voice traffic is mapped and transferred over pre-established connections between the gateway and the UEs of the specific group.Type: GrantFiled: December 13, 2001Date of Patent: September 7, 2010Assignee: Nokia CorporationInventor: Juha Karjanlahti
