Patent number: 8441933Abstract: Aspects of the invention pertain to routing packets in a computer system while avoiding deadlock. A turn rule is set according to unique identifiers associated with switches in the system. Numeric values of switches in possible turns are compared to determine whether a turn is permissible. The rule applies to all nodes in the system. The rule may be violated when using virtual channels. Here, a violation is permissible when using monotonically increasing virtual channel numbers or monotonically decreasing virtual channel numbers. Alternatively, the violations of the turn rule may be allowed if they force a packet to change to a later virtual channel in some fixed ordering of virtual channels. Deadlock can thus be avoided in many different types of architectures, including mesh, torus, butterfly and flattened butterfly configurations.Type: GrantFiled: February 6, 2012Date of Patent: May 14, 2013Assignee: Google, Inc.Inventor: Peter Michael Klausler

Patent number: 8441938Abstract: The present invention relates to methods and arrangements for uplink retransmissions from a user equipment to a radio base station in a UTRAN with enhanced uplink. The UE transmits a subframe comprising physical control channel(s) and physical data channel(s) in an initial transmission. According to the present invention, one or more of the physical control channels are transmitted with a lower transmission power level in all or some of the retransmitted subframes in the uplink. This results in reduced control overhead (a smaller part of the transmission power resource is used for control signaling) and thus reduced interference from the overhead. At the same time, the transmission power resource no longer used for the physical control channel information, can be used to increase the transmission power level of the physical data channel information in these retransmitted subframes, which improves the uplink coverage.Type: GrantFiled: December 10, 2008Date of Patent: May 14, 2013Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Markus Ringström, Dirk Gerstenberger, Johan Bergman

Patent number: 8441962Abstract: A method and corresponding device and system to provide a real-time call announcement to a called device. According to the method, a called device begins receiving call announcement media without having first engaged in session setup signaling to set up a session through which to receive the call announcement media. In normal operation, the device would disregard such incoming media, since no session has been set up for receiving the media. As disclosed, however, the device will also receive at about the same time a call setup request that seeks setup of the underlying call, and the device will treat its receipt of that call setup request as a key to allow playout of the call announcement media even though no session has been set up for receipt of the call announcement media. The called device will then play out the call announcement media as an announcement for the call.Type: GrantFiled: April 9, 2010Date of Patent: May 14, 2013Assignee: Sprint Spectrum L.P.Inventors: Jeremy R. Breau, Jason R. Delker, Manish Mangal, Mathew Oommen

Patent number: 8441968Abstract: Systems and methods are provided for processing a payload portion of a received signal in a single carrier mode or a multiple carrier mode based on a portion of the received signal. A single carrier signaling portion is received at a first rate, and whether the payload portion of the signal is a single carrier signal or a multiple carrier signal is detected from the received single carrier signaling portion. The payload portion of the received signal is received at the first rate and demodulated in a single carrier mode if the detecting determines that the payload portion of the received signal is a single carrier signal, and the payload portion of the received signal is demodulated in a multiple carrier mode if the detecting determines that the payload portion of the received signal is a multiple carrier signal.Type: GrantFiled: June 23, 2009Date of Patent: May 14, 2013Assignee: Marvell World Trade Ltd.Inventors: Hongyuan Zhang, Rohit U.

Patent number: 8441972Abstract: A WCDMA enabled user equipment device configured to have functions collectively or selectively idle to conserve power. A discontinuous receiver is used to detect and read network messages and report the messages to the host processor within the WCDMA enabled user equipment device. The host processor then activates functions previously powered down to receive incoming messages for the user of the WCDMA device. The discontinuous receiver is also used when the WCDMA device is active to read network messages, freeing a modem of the device to operate on user messaging; and therefore, enhancing user related performance.Type: GrantFiled: November 16, 2005Date of Patent: May 14, 2013Assignee: QUALCOMM IncorporatedInventors: Michael Kohlmann, Tae Hea Nahm, Beomsup Kim, Cormac Conroy

Patent number: 8441975Abstract: Medium accessing mechanisms within multiple user, multiple access, and/or MIMO wireless communications. A multi-user super-frame (MU-SF), as controlled by a MU-SF owner, is used to govern the manner by which various wireless communication devices have access to the communication medium. When various wireless communication devices operate within a wireless communication system, communication medium access can be handled differently for wireless communication devices having different capabilities. Per the MU-SF, those having a first capability may get medium access in accordance with a first operational mode (e.g., carrier sense multiple access/collision avoidance (CSMA/CA)), while those having a second capability may get medium access in accordance with a second operational mode (e.g., scheduled access).Type: GrantFiled: June 22, 2010Date of Patent: May 14, 2013Assignee: Broadcom CorporationInventors: Peiman Amini, Matthew James Fischer, Vinko Erceg, Joseph Paul Lauer, Joonsuk Kim
