Publication number: 20200084774Abstract: Techniques for supporting peer-to-peer (P2P) communication in a wide area network (WAN) are disclosed. In an aspect, interference coordination between P2P devices engaged in P2P communication and WAN devices engaged in WAN communication may be performed based on a network-controlled architecture. For the network-controlled architecture, P2P devices may detect other P2P devices and/or WAN devices and may send measurements (e.g., for pathloss, interference, etc.) for the detected devices to the WAN (e.g., serving base stations). The WAN may perform resource partitioning and/or association for the P2P devices based on the measurements. Association may include selection of P2P communication or WAN communication for a given P2P device. Resource partitioning may include allocation of resources to a group of P2P devices for P2P communication.Type: ApplicationFiled: November 14, 2019Publication date: March 12, 2020Inventors: Stefan GEIRHOFER, Naga BHUSHAN, Ravi PALANKI, Jaber BORRAN, Aleksandar DAMNJANOVIC

Patent number: 8892108Abstract: Systems and methodologies are described that facilitate defining control channels and resource identifiers related thereto as well as constraints for utilizing the control channels. A minimum number of required control reports for a set of resource indices can be specified as a constraint to provide a mobile device flexibility with respect to transmitting the control reports over available resource indices. Additionally, or alternatively, a maximum number of control reports can be specified for transmitted over the resource indices to prevent control channel overload. Moreover, a constraint can specify an exact number of control channels to utilize in transmitting control reports. Other constraints are possible as well, such as limiting a control report payload or change in payload, limiting out-of-band control reports based on in-band reports transmitted, etc.Type: GrantFiled: January 29, 2008Date of Patent: November 18, 2014Assignee: QUALCOMM IncorporatedInventors: Mohammad Jaber Borran, Alexei Gorokhov, Aamod Khandekar

Patent number: 8670777Abstract: Systems and methods that facilitate management of interference and communication resources are provided. A differential approach is devised in which other-sector interference (OSI) and communication resources are managed by adjusting an offset (delta) value associated with the resources in response to receiving an indication of other-sector interference. An OSI indication can be issued based on a short and a long time scale, and effective interference metrics over time-frequency resources. The adjusted delta value is communicated to a serving access point, which reassigns communication resources in order to mitigate other-sector interference.Type: GrantFiled: September 4, 2007Date of Patent: March 11, 2014Assignee: QUALCOMM IncorporatedInventors: Mohammad Jaber Borran, Alexei Gorokhov, Aamod Khandekar, Tingfang Ji, Arumugam Chendamarai Kannan

Patent number: 7889804Abstract: A signal constellation for a multiple input/multiple output (MIMO) communication system when channel knowledge at the receiver is imperfect includes at least two (n?1)-dimensional sub-constellations of points that together form an n-dimensional constellation, the number n representing real dimensions and n=2M where M is the number of transmit antennas. The n-dimensional spherical constellation may define a single sphere or a plurality of concentric subset spheres, and points between subsets are separated by a Kullback-Leibler distance rather than a Euclidian distance. Each sphere has sub-constellations that preferably are arranged in symmetric pairs that define equal numbers of points that lie in parallel planes, to allow recursive construction that minimizes computational complexity. An appropriate constellation may be chosen by ceasing a search once the optimum minimum distance stops increasing as a number of the concentric levels increases.Type: GrantFiled: September 24, 2003Date of Patent: February 15, 2011Inventors: Mohammad Jaber Borran, Ashutosh Sabharwal, Behnaam Aazhang, Prabodh Varshney

Patent number: 7394865Abstract: A signal constellation for wireline or wireless multi-carrier communication systems, such as systems using OFDM or MC-CDMA, has points separated from one another by maximizing a distance between conditional probability distributions, such as a Kullbeck-Leibler (KL) distance. Preferably, the constellation points are arranged in concentric circles, with or without a point at the origin, wherein adjacent circles are rotated to maximize an angular distance between points on adjacent circles. Pilot symbols inserted in the transmitted signal are used by a receiver to estimate the channel of the multi-carrier system. Different constellations show optimum performance for different signal to noise ratios, and for different numbers of taps used to estimate the channel, especially in a fast fading environment where there may be fewer pilots per OFDM or MC-CDMA symbol than channel taps.Type: GrantFiled: June 25, 2003Date of Patent: July 1, 2008Assignee: Nokia CorporationInventors: Mohammad Jaber Borran, Prabodh Varshney, Jorma Lilleberg

Patent number: 7313168Abstract: A hybrid receiver, and an associated method, for receiving a radio signal carrying transmitted data that is subject to distortion in the transmission channel. The receiver includes a plurality of stages that perform parallel interference cancellation (PIC) to establish successively more accurate estimates of the transmitted data, including a receiver first stage being either a RAKE receiver or a linear minimum mean-square error (LMMSE) receiver, a second stage including an LMMSE, and preferably a third stage also including an LMMSE. Each stage processes the estimates of the transmitted signal provided by the stage preceding it to mitigate or eliminate as much transmission-channel interference as possible and prove a refined estimate for processing by subsequent stages. Improved channel estimation may be achieved by processing the pilot signal in similar fashion as well.Type: GrantFiled: March 24, 2003Date of Patent: December 25, 2007Assignee: Nokia CorporationInventors: Panayiotis D.
