  • Patent number: 9544911
    Abstract: System and method for assigning communications resources in a wireless communications system. A method for operating a base station comprises receiving a resource request for radio resources for a mobile station, in response to a determining that the base station will service the resource request, assigning radio resources based on the resource request and transmitting an indicator of the assigned radio resources to the mobile station, and in response to a determining that the base station will not service the resource request, returning to a normal mode of operations. The assigning of radio requests makes use of a channel tree comprised of two non-orthogonal sets of mappings between nodes of the channel tree and radio resources, with each node corresponding to at least one radio resource.

  • Patent number: 9503948
    Abstract: First data packets for a wireless device are received from a data source at a network element, and are encoded into at least one second data packet using a data redundancy factor, where the at least one second data packet comprising at least two of the first data packets. The at least one second data packet is provided to an access node and is sent from the access node to the wireless device over a first frequency band. A round trip time of at least one of the first data packets is determined at the data source, and further a frequency band load of the first frequency band is determined. A handover is performed of the wireless device from the first frequency band to a second frequency band based on the round trip time and the frequency band load of the first frequency band.

  • Patent number: 9445380
    Abstract: An exemplary method of communicating includes a relay node that uses a cell identifier that is also used by a base station having a coverage area within which the relay node is located. The method includes determining that a mobile station is within a communication range of the relay node. A transmission power from the relay node is controlled so that the total transmission power of at least one transmission from the relay node and the base station corresponds to a selected transmit power limit. A timing of a downlink transmission from the base station and the relay node is coordinated based on a schedule determined by the base station. At least one uplink control parameter is set at the base station based upon uplink information regarding a link between the mobile station and the relay node.

  • Patent number: 9439199
    Abstract: Techniques for transmitting power decision pilots are described. A transmitter (e.g., a base station or a UE) may transmit a power decision pilot to indicate a transmit power level that it will use on subsequent time-frequency resources. In one design, the transmitter may determine a set of time-frequency resources to use for transmitting the power decision pilot, determine the transmit power level for the power decision pilot based on the transmit power level to use for data transmission, and transmit the power decision pilot on the set of time-frequency resources to indicate the transmit power level to use for data transmission on the subsequent time-frequency resources. A receiver (e.g., a UE or a base station) may receive power decision pilots from a set of transmitters and may estimate channel quality that the receiver can expect on the subsequent time-frequency resources based on the power decision pilots.

  • Patent number: 9408122
    Abstract: A method of obtaining system frame number for handover is provided. A UE receives a handover command from a serving base station in a serving cell. The UE performs downlink synchronization with a target base station. Upon synchronization, the UE determines a radio frame boundary of a target cell. The UE then obtains a system frame number of the target cell based on the radio frame boundary. The UE performs a handover procedure with the target cell by transmitting a RACH preamble to the target base station. The RACH preamble is transmitted over a PRACH resource determined from the system frame number without reading SFN information from a PBCH/BCH broadcasted from the target base station. Finally, the UE establishes data connection with the target base station. Handover interruption time is reduced by obtaining SFN before PBCH reading and decoding.

  • Patent number: 9398464
    Abstract: Certain aspects are directed to a base station router disposed in a distributed antenna system. The base station router includes a backplane and a controller. The backplane can manage an availability of sectors for coverage zones. Each sector can include communication channels to be radiated to mobile devices in the coverage zones and can represent an amount of telecommunication capacity. The controller can respond to a traffic indicator by causing the backplane to redistribute the availability of at least one sector. The sector can be redistributed from a first coverage zone to a second coverage zone.

  • Patent number: 9380480
    Abstract: A mobile wireless communication device efficiently uses memory when performing a minimization drive test (MDT) by storing less than all of the MDT measurements. The mobile wireless communication device receives a control signal comprising MDT configuration parameters indicating at least a measurement interval. When executing the MDT, the mobile wireless communication device measures a signal characteristic of measurement signals in accordance with the MDT configuration parameters to generate a number of measurements for a measurement period. Rather than storing all of the measurements, only a number of log values corresponding to the measurements are stored in memory, where the number of log values is less than the number of measurement values.

  • Patent number: 9351171
    Abstract: A technique for designing and testing drive-test plan for gathering location-dependent RF data is disclosed. In accordance with some embodiments of the present invention, one candidate drive-test plan is chosen for implementation over a second based on an economic cost-benefit analysis of both plans. This is in marked contrast to, for example, a selection of drive-test plans, or the design of a drive-test plan, based on a calibration-cost analysis, in which the data estimated to be the most effective to calibrate a radio-frequency tool is sought for a given cost or the least cost. Although a data-estimated-to-be-most-effective-to-calibrate-a-radio-frequency-tool vs. cost analysis is a species of cost-benefit analyses in general, it is not an economic cost-benefit analysis because a data-estimated-to-be-most-effective-to-calibrate-a-radio-frequency-tool vs. cost analysis has deficiencies that an economic cost-benefit analysis does not.
