  • Patent number: 9143953
    Abstract: Methods and devices for transmission of communications during a silence interval are described. A base station (BS) provides timing data to an access terminal (AT) and AT uses timing data to synchronize with BS to carry our silence and non-silence intervals for an RF air interface. AT attempts to initiate communications by transmitting an access probe (AP) to BS during a non-silence interval. Other ATs may transmit communications to BS during non-silence interval. If BS acknowledges AP during non-silence interval, AT does not transmit during a subsequent silence interval. If AP was for an emergency communication and BS does not acknowledge AP sent during non-silence interval, AT transmits another AP during the subsequent silence interval to initiate emergency communication. If AP was not for emergency communication, AT does not transmit AP during the subsequent silence interval. The other ATs do not transmit communications to BS during the subsequent silence interval.

  • Patent number: 9088512
    Abstract: A mobile station involved in a call receives a forward link signal from a radio access network (RAN) and transmits a reverse link signal to the RAN. If the mobile station detects a reception failure of the forward link signal, such as the receipt of an errored frame, the mobile station transmits a wait time to the RAN. The wait time specifies how long the reception failure can continue before the mobile station will discontinue transmitting the reverse link signal. In response, the RAN may increase the transmit power level at which the RAN transmits the forward link signal, such that a maximum transmit power level is reached during the wait time. The wait time could be based on a user preference and/or user behavior with respect to abandoning calls.

  • Patent number: 9071431
    Abstract: Disclosed is a method and corresponding apparatus to make use of hybrid-ARQ repetition factors as a way to differentiate service quality to various mobile terminals. Depending on a mobile terminal's subscription service class, such as the mobile terminal's PLMN, the mobile terminal may be made to use a particular hybrid-ARQ repetition factor. For instance, a mobile terminal of a high service class may be made to use a low hybrid-ARQ repetition factor, which may help the mobile terminal experience less downlink transmission delay and thus a higher downlink data rate. Whereas, a mobile terminal of a low service class may be made to use a high hybrid-ARQ repetition factor, which may cause the mobile terminal to experience more downlink transmission delay and thus a lower downlink data rate, and may further free up downlink transmission resources to facilitate better service for other mobile terminals.

  • Patent number: 9055504
    Abstract: A serving base station (SBS) that provides service to a UE device can receive or determine admission capacity of a neighbor base station (NBS). The SBS can determine a reporting interval based on the admission capacity and provide the UE device with the reporting interval. Upon determining that handover from the SBS to the NBS may be necessary, the UE device can responsively start transmitting measurement data regarding the NBS to the SBS. Transmission of the measurement data can occur at intervals that equal the reporting interval. The value of the reporting interval can be conditioned on the admission capacity of the NBS. As the capacity for admitting more UE devices decreases, the likelihood of the UE device handing over to the NBS may decrease. Increasing the reporting interval for reporting measurement data regarding the NBS can reduce loading of the reverse-links to the SBS.

  • Patent number: 9042898
    Abstract: An inter-frequency handoff of a mobile station engaged in a call via wireless network is effected by gradually changing a carrier frequency of a forward link signal from a first-channel frequency, corresponding to a first frequency channel, to a second-channel frequency, corresponding to a second frequency channel. Initially, a first transmitter in the wireless network transmits the forward link signal in the first frequency channel. A second transmitter then transmits the forward link signal while changing the carrier frequency from the first-channel frequency to the second-channel frequency at a specified tuning rate. The tuning rate may be dynamically adjustable in response to requests from the mobile station. Once the second-channel frequency is reached, a third transmitter continues transmitting the forward link signal in the second frequency channel. The mobile station may also gradually change the carrier frequency of the reverse link signal that it transmits for the call.
