Patent number: 8374619Abstract: Embodiments of the invention provide for allocating spectrum in a wireless communication system that supports simultaneously at least a first mode of operation and a second mode of operation. Logic is arranged for determining a proportion of spectrum required for the wireless communication unit to operate simultaneously in both the first mode of operation and the second mode of operation. Logic for allocating spectrum allocates a temporary guard band between a first portion of spectrum for the first mode of operation and a second portion of spectrum for the second mode of operation for use while the wireless communication unit operates simultaneously in the first mode of operation and second mode of operation.Type: GrantFiled: June 24, 2010Date of Patent: February 12, 2013Assignee: Nvidia CorporationInventors: Alan Edward Jones, Peter Bruce Darwood, Paul Howard

Patent number: 8243709Abstract: A method (400) and arrangement (200) for mitigation of intercell and intracell interference in a 3GPP cellular communication system (100) by, in a receiver in a cell of the system, deriving for a first channel in the cell a signal, representative of first channel transfer function (A(1)); deriving for at least a second channel originating in a different cell a signal (A(2 . . . M)), representative of second channel transfer function, based on: deriving a cell specific scrambling code (s), deriving a channel impulse response (h), and deriving a channelization code (c); and performing multi-user detection using the first and second signals. Where the channelization code is unknown, a substitute channelization code is preferably substituted. It will be appreciated that the technique can be applied to both downlink and uplink. This provides the advantage that both intra-cell interference and intercell interference are mitigated.Type: GrantFiled: February 22, 2011Date of Patent: August 14, 2012Assignee: Nvidia CorporationInventor: Alan Edward Jones

Patent number: 8081597Abstract: Aspects of the invention include a root node of a wireless communication infrastructure that buffers data packets for transmission by base stations over an air interface. The root node determines a time delay for transmission of a data packet from the root node to each base station, a maximum time delay of those time delays, and a timing latency based upon the maximum time delay. The root node transmits the timing latency to the base stations. In response, each base station initiates transmission of data packets received by the root node after expiration of the timing latency. Alternatively, the root node, instead of the base stations, may buffer the data packets, and transmit them so that they arrive at the base stations at substantially the same time.Type: GrantFiled: April 29, 2010Date of Patent: December 20, 2011Assignee: IPWireless, Inc.Inventors: Alan Edward Jones, William John Jones

Patent number: 8045599Abstract: A cellular communication system comprises a Multiple-In Multiple-Out, MIMO, transmitter (101) and receiver (103). The MIMO transmitter (101) comprises a message generator (303) for generating MIMO messages comprising selected training sequences and transceivers (305, 307, 309) transmitting the messages on a plurality of antennas (311, 313, 315).

The set of training sequences is associated with the cell of the MIMO transmitter and comprises disjoint subsets of training sequences for each of the plurality of antennas. The receiver (103) comprises a transmit antenna detector (419) which determines which antenna of the MIMO transmitter the message is transmitted from in response to the training sequence of the received message.Type: GrantFiled: February 17, 2005Date of Patent: October 25, 2011Assignee: Sony CorporationInventors: Peter B.

Patent number: 7792179Abstract: An efficient scheme for CDMA coding constructs codes by generating longer code sequences (430) via concatenation, from an existing set of short sequences (410, 420). The sequences may be spreading, scrambling and or training or channel estimation (such as midamble) sequences. The invention allows extension of sequences without performing an exhaustive search for sequences with optimal desired properties, as well as extension of the sequence duration to improve the detection of wanted signals via the use of a conventional matched filter, a multi-user detector or an adaptive filter/equaliser.Type: GrantFiled: November 3, 2003Date of Patent: September 7, 2010Assignee: IPWireless, Inc.Inventors: Peter Bruce Darwood, Alan Edward Jones

Patent number: 7369601Abstract: Processing of a received code division multiple access, CDMA, burst (405) when a spreading factor of the CDMA burst (405) has been changed from an allocated spreading factor (SF0) to a new spreading factor (SFn). The received burst (405) is processed with a CDMA detector (310), using the allocated spreading factor (SF0), to provide a CDMA detector output; the new spreading factor (SFn) of the burst is determined; and the CDMA detector output is decimated by a factor determined from the new spreading factor (SFn). The decimator may be a FIR decimator (315) and tap weights may be determined using the values of the new spreading factor (SFn) and the allocated spreading factor (SF0). Application in a Node B (150A) of a UMTS system (100), particularly in UTRA TDD mode, for processing received uplink communication is described.Type: GrantFiled: October 24, 2002Date of Patent: May 6, 2008Assignee: IPWireless, Inc.Inventors: Alan Edward Jones, David Trewren
