Publication number: 20130163440Abstract: A network-based wireless location system (WLS) is configured to locate mobile devices, or user equipment (UE), wirelessly communicating with a relay node (RN). The RN is wirelessly backhauled to a serving donor enhanced NodeB (donor eNB), and the RN has eNB functionality to communicate with the UE and has UE functionality to communicate data from the UE with the donor eNB. The WLS carries out a method including receiving uplink transmissions from the RN, using the uplink transmissions from the RN to compute a location estimate for the RN, and determining a location estimate for the UE based on the location estimate for the RN.Type: ApplicationFiled: December 27, 2011Publication date: June 27, 2013Applicant: TRUEPOSITION, INC.Inventors: Simon Issakov, Matthew L.

Patent number: 8442538Abstract: For Wireless Communications Networks (WCNs) that support soft handover, cooperator receiver selection for a TDOA, AOA, TDOA/AOA, or hybrid network-based or network-overlay Wireless Location System (WLS) must contend with one or more network base stations as a serving cell. When the active set contains more than one member, two techniques for determining a set of cooperating and demodulating receivers to use in the signal collection for location estimation is disclosed. In one embodiment, the active set members are constructively reduced to a single member that is used as a proxy serving cell. In another embodiment, the information contained in the active set membership is retained and a new set of demodulating and cooperator receivers are generated based on the entire membership of the active set.Type: GrantFiled: December 29, 2009Date of Patent: May 14, 2013Assignee: TruePosition, Inc.Inventors: Edward Joseph Segall, Simon Issakov, Rashidus S.

Patent number: 8331386Abstract: In one embodiment, a method for processing a transport block having a MAC-hs protocol data unit (PDU) and a corresponding checksum in an HSDPA-compatible (high-speed downlink packet access) receiver in a 3GPP wireless communication network, the method including: (a) recovering the transport block, (b) performing, substantially in parallel: (i) a cyclic redundancy check (CRC) on the transport block to determine whether the transport block passes or fails, and (ii) MAC (media access control) disassembly to generate a modified MAC-hs PDU, and (c) determining whether to perform reordering-queue distribution and reordering on the modified MAC-hs PDU based on whether the transport block passes or fails. By performing the CRC check and disassembly substantially in parallel, processing efficiencies may be gained.Type: GrantFiled: May 31, 2007Date of Patent: December 11, 2012Assignee: Agere Systems LLCInventors: Rafael Carmon, Simon Issakov

Publication number: 20120020320Abstract: In an overlay, network-based, wireless location system, LMUs typically co-located with BTSs are used to collect radio signaling both in the forward and reverse channels for use in TDOA and/or AOA positioning methods. Information broadcast from the radio network and by global satellite navigation system constellations can be received by the LMU and used to reduce the difficulty of initial system configuration and reconfiguration due to radio network changes.Type: ApplicationFiled: July 23, 2010Publication date: January 26, 2012Applicant: TRUEPOSITION, INC.Inventors: Simon Issakov, Rashidus S.

Patent number: 7912028Abstract: In one embodiment, a method for determining whether an encoded message in a shared channel is not intended for a communications device. The method includes: (a) decoding the message to recover a multi-bit codeword; (b) determining whether the codeword is valid or invalid, wherein, if the codeword is determined to be invalid, then the encoded message is not intended for the communications device; and (c) if the codeword is determined to be valid, then performing one or more other steps of the method to determine whether the encoded message in the shared channel is not intended for the communications device.Type: GrantFiled: May 31, 2007Date of Patent: March 22, 2011Assignee: Agere Systems Inc.Inventors: Eliahou Arviv, Rafael Carmon, Simon Issakov

Publication number: 20100220638Abstract: In one embodiment, a method for processing a series of MAC-hs protocol data units (PDUs) in an HSDPA-compatible (high-speed downlink packet access) receiver in a 3G wireless communication network, the method including: (a) receiving a MAC-hs PDU having: (i) a queue identification (QID), (ii) a transmission sequence number (TSN), and (iii) one or more MAC-d PDUs, (b) then disassembling the MAC-hs PDU (c) then distributing the one or more MAC-d PDU to a reordering queue indicated by the QID, and (d) then performing reordering processing for the corresponding reordering queue based on the TSN. Steps (a) and (b) are performed in a physical layer of the receiver. Steps (c) and (d) are performed in a data-link layer of the receiver.Type: ApplicationFiled: February 7, 2007Publication date: September 2, 2010Applicant: AGERE SYSTEMS INC.Inventors: Rafael Carmon, Simon Issakov

Patent number: 7738369Abstract: In one embodiment, a transmitter (a) caches one or more MAC-d PDUs received from a network layer, (b) selects a subset of the MAC-d PDUs for combination into a MAC-e PDU, (c) generates the MAC-e PDU from the subset of selected MAC-d PDUs, (d) caches a data structure to allow re-generation of the MAC-e PDU, wherein the re-generation does not rely on any cached copy of the MAC-e PDU, (e) transmits the MAC-e PDU for receipt by a receiver; and (f) determines whether an ACK was received, wherein if an ACK was not received, then the MAC-e PDU is re-generated using the cached data structure and the subset of selected MAC-d PDUs, and steps (e) and (f) are repeated, and if an ACK was received, then the memories used to cache the data structure and the first subset of MAC-d PDUs are freed.Type: GrantFiled: January 17, 2007Date of Patent: June 15, 2010Assignee: Agere Systems Inc.Inventors: Rafael Carmon, Ido Gazit, Simon Issakov, Vladimir Kopilevitch
