Abstract: One or more indications of signal quality as measured by a wireless communication device (WCD) served by a radio access network (RAN) may be transmitted from the WCD to the RAN. A determination may be made that the one or more indications of signal quality meet or exceed a threshold signal quality. Possibly based on the one or more indications of signal quality meeting or exceeding the threshold signal quality, the WCD may bundle at least some hybrid automatic repeat request (HARD) acknowledgments that the WCD transmits to the RAN.

Abstract: A base station is configured for latency-based contention free preamble reuse. The base station determines the latency between it and each of a plurality of neighboring stations and, in response to receiving two different handover requests for two different UEs from two different neighboring base stations, the base station assigns one contention free preamble for use by both of the two UEs based at least in part on respective latencies from the base station to each of the two different neighboring base stations.

Abstract: Embodiments described herein may help to provide a delayed zone-update process. An exemplary method may involve a user entity, which is initially operating in a first of a plurality of multi-coverage-area zones in a radio access network (RAN), subsequently determining that the user entity has moved into a second multi-coverage-area zone of the RAN, wherein the user entity is located in a first coverage area of the second multi-coverage-area zone. In response, the user entity may refrain from sending a registration message to register in the second multi-coverage-area zone until the earlier of: (i) a threshold period of time elapsing and (ii) the user entity moving into another coverage area in the second multi-coverage-area zone that is different from the first coverage area.

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.

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.

Abstract: During an initial part of a communication session, a transmitting node transmits digital data over a first air interface channel to a receiving node, using a first data rate and a first level of repetition. A degradation in quality of the communication session is detected. During a subsequent part of the communication session, the transmitting node transmits digital data over the first air interface channel as before but also transmits the digital data over a second air interface channel, using a second data rate and a second level of repetition. The second data rate is higher than the first data rate, and the second level of repetition is higher than the first level of repetition. Thus, during a given transmission period, the transmitting node may transmit a voice frame once over the first air interface channel and N times over the second air interface channel.

Abstract: A method and apparatus to help minimize tuneaway time of a user equipment device (UE), by dynamically scheduling when the UE should tune away to scan for coverage of a particular wireless communication system, such as a time division duplex (TDD) system for instance. The UE may receive downlink transmissions from a TDD system and determining a downlink transmission schedule of the TDD system based on when those downlink transmissions occurred. Further, the UE may then use the determined downlink transmission schedule as a basis to schedule tuneaway of the UE from a serving system to scan for coverage of the TDD system.

Abstract: A method, apparatus, and system for helping to manage advanced handoff to a coverage area based on correlation with a geographic region. A mobile station determines that it is in or approaching a defined geographic region, and the mobile station determines from correlation data that the geographic region is correlated with a particular cellular coverage area. The mobile station therefore requests handoff to the cellular coverage area and provides an advanced-handoff indication to cause the serving radio access network to maintain assignment of a radio connection in the coverage area longer than the network would normally, to help allow time for the mobile station to arrive at the coverage area and begin communicating on the radio connection with the network.

Abstract: In one aspect, an exemplary method involves a WCD: (i) determining a likelihood of roaming, wherein the likelihood of roaming indicates a likelihood that the WCD will be handed off from a preferred coverage area to a non-preferred coverage area; and (ii) using the likelihood of roaming as a basis for managing an active set of the WCD. In particular, the WCD may manage its active set by setting at least one active-set parameter affecting the number of active sectors in an active set of the WCD, and then maintaining its active set according to the setting of the at least one active-set parameter. According to an exemplary embodiment, a WCD will make an effort to increase the number of sectors in its active set when the likelihood of roaming is greater, and vice versa.
