  • Patent number: 8565684
    Abstract: A communication device and method for controlling reverse link transmissions. The device receives a broadcast transmission signal and determines a quality level of the broadcast transmission signal. It then communicates with the base station to establish how frequently reverse link transmissions will occur depending on the determined quality level. Alternatively, a network element can determining when a parameter crosses a threshold and transmit a message to select wireless communication devices to start gating on a reverse link when the parameter crosses the threshold.

  • Patent number: 8559458
    Abstract: A method and scheduler are provided that optimize utilization of an uplink (UL) data packet field of an UL sub-frame. In one embodiment, a request for an allocation of bandwidth is received from each of multiple mobile stations. The requests include requests for a bandwidth allocation of a first size range and requests for a bandwidth allocation of a second size range, wherein each request of the second size range requests more bandwidth than any request of the first size range. Bandwidth is allocated in a UL data packet field to the requests in order of priority, and when the allocated bandwidth does not fill the UL data packet field and a request of the second size range remains unallocated, an allocation of bandwidth to an unallocated request of the second size range is substituted for an allocation of bandwidth to a request of the first size range.

  • Patent number: 8560016
    Abstract: A method and system configures operating parameters associated with an operation of a connected accessory or second device in order to mitigate harmonic interference within an operating frequency band of a wireless communication device (WCD). In response to a connection between the WCD and the second device via a physical communications interface, Accessory Authentication and Configuration (AAC) logic of the WCD receives device identifying information about the second device. The AAC logic determines candidate values for each operating parameter, based on the device identifying information. The AAC logic dynamically selects a particular candidate value for each operating parameter, based on a current operating frequency band of the WCD, and an expected level of harmonic interference.

  • Publication number: 20130265953
    Abstract: A method for triggering a group of one or more detached wireless communication devices (122) to attach to a wireless communications network (101) for enabling data communications is disclosed. A trigger request message including a group identifier, size information for the group, and location information for the one or more wireless communication devices (122) is received (302) at the network (101). Based on this information, the network (101) determines (304) a delay time period during which the one or more wireless communication devices (122) are to transmit an access request message to the network (101) when triggered to attach to the network. The delay time period is based on the size of the group. During a trigger period, the delay time period and group identifier is transmitted (306) to the one or more wireless communication devices (122) in a trigger message. A wireless communication device (122) is also described.

  • Patent number: 8553594
    Abstract: A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced.

  • Patent number: 8553637
    Abstract: A method, system, and base station for deterministically selecting a downlink transmission mode and rank in a Long Term Evolution (LTE) configured wireless communication system. The Transmission Mode Selection (TMS) utility receives from a wireless device a request for downlink physical downlink shared channel (PDSCH) service using a particular transmission mode and specific rank. The TMS utility determines an estimate of the throughput corresponding to the request. In addition, the TMS utility obtains throughput estimates of other distinct pairings of transmission mode and rank to compare with the throughput estimate corresponding to the request. The TMS utility utilizes device feedback information and HARQ error information that are already existing/available in order to determine the best transmission mode and rank pair, according to the best Error-Adjusted-Throughput.
