  • Publication number: 20120281593
    Abstract: A broadband cellular network (BCN) provides a user equipment (UE) access to TVWS resources. The BCN authorizes the UE to access TVWS resources by conveying a mobile device identifier received from the UE, and a cell identifier associated with the UE's coverage area, to a Federal Communications Commission (FCC)-certified Database and receiving, from the Database, and storing an FCC ID associated with the UE and a set of available TVWS resources. The BCN then conveys, to the UE via a broadband cellular technology, a channel resource information element (CRIE) that includes the cell identifier and identifies the set of available TVWS resources. Subsequently, the BCN re-authorizes the UE to access TVWS resources based on the stored FCC ID and without re-conveying the mobile device identifier to the Database. The BCN further utilizes broadband cellular technology procedures to provide a “virtual” contact verification signal (VCVS) to the UE.

  • Publication number: 20120257519
    Abstract: A method and apparatus for a co-scheduler can mitigate UE-to-UE adjacent carrier frequency band interference by allocating three sets to a first user equipment uplink. Each set has at least one sub-carrier in a first frequency band, at least one uplink time period, and at least one transmission power parameter. The co-scheduler initially allocates the first set. The co-scheduler allocates the second set in response to detecting a second user equipment operating proximal to the first user equipment, and the second set differs from the first set in either at least one sub-carrier or at least one transmission power parameter. The co-scheduler allocates the third set in response to detecting that the second user equipment is no longer operating proximal to the first user equipment, and the third set differs from the second set in either at least one sub-carrier or at least one transmission power parameter.

  • Publication number: 20120236736
    Abstract: A method (500) and apparatus for multi-radio coexistence has a victim user equipment (UE) that receives (515) a sequence of subframes at a first transceiver from a serving base station, measures (520) channel state on the subframes to obtain channel state measurements, determines (530) a high-low interference pattern based on the channel state measurements, and transmits (550) to the serving base station a report that includes an indicator related to the high-low interference pattern. The method can include the victim UE receiving (610) an aggressor reference waveform (ARW) from the second transceiver, determining (620) spatial characteristics of the second transceiver from the ARW, and configuring (630) its antenna system based on the spatial characteristics. The method can have the victim UE determining (640) second transceiver characteristics from the ARW and transmitting (650) information regarding the second transceiver characteristics to its serving base station.

  • Publication number: 20120172041
    Abstract: The cell searcher module (CSM) of a wireless communication device detects that the device is in coverage region of an eNB by processing received signal associated with the primary synchronization (PSCH) and secondary synchronization (SSCH) sequences transmitted by the eNB. The wireless device determines whether candidate SCH signals from candidate neighbor cells are synchronous with SCH sequences from the serving cell by implementing one of three methods. In a first method, the CSM generates a joint estimate of the received power of SSCH sequences corresponding to already detected/identified serving cell and a hypothetical neighbor cell. In a second method, the CSM re-constructs SCH sequences corresponding to already detected cells and subtracts the re-constructed SCH sequences from the received signal to obtain a residual signal with reduced serving cell interference. In a third embodiment, the CSM performs a correlation of estimated channel responses to determine whether the neighbor cell is present.

  • Publication number: 20120164948
    Abstract: A wireless terminal that supports operation on a first wireless technology and operation on a second wireless technology performs a first set of measurements on a received signal on first operating frequency of the first wireless technology, wherein the first set of measurements are performed during time periods that overlap time periods during which the wireless terminal transmits signals of the second wireless technology. The terminal also performs interference avoidance to avoid interference from transmissions of signals of the second wireless technology to reception of signals of the first wireless technology if the first set of measurements indicates interference due to transmission of signals of the second wireless technology by the wireless terminal.

    Abstract: A mobile terminal receives a transmission from a base station including a group of Nprs consecutive subframes, where Nprs is a number of subframes constituting the group, and each subframe is capable of transmitting a positioning reference signal (PRS). The group of Nprs consecutive subframes is configured such that a transition between a subframe that does, or does not, include a PRS transmission to a subsequent subframe that does not, or does, include a PRS transmission can occur only after an even number of subframes 2*k, where k=0, 1, 2 . . . . The mobile terminal determines an estimated time of arrival of the transmission from the base station based on a portion of the transmission that includes a PRS transmission.

  • Publication number: 20100260154
    Abstract: A base station communicates a positioning reference signal (PRS) to wireless communication devices over a downlink in a wireless communication system by encoding a PRS into a first set of transmission resources, encoding other information into a second set of transmission resources, multiplexing the two sets of resources into a subframe such that the first set of resources is multiplexed into at least a portion of a first set of orthogonal frequency division multiplexed (OFDM) symbols based on an identifier associated with the base station and the second set of resources is multiplexed into a second set of OFDM symbols. Upon receiving the subframe, a wireless communication device determines which set of transmission resources contains the PRS based on the identifier associated with the base station that transmitted the subframe and processes the set of resources containing the PRS to estimate timing (e.g., time of arrival) information.
