  • Patent number: 9793980
    Abstract: Systems and methods for real-time signal validation are disclosed. In an example embodiment, a subset of terminals in a peer group of satellite terminals is determined. Operational statistics of the satellite terminals in the subset of terminals is measured. Operational statistics of each of the satellite terminals in the subset of terminals is compared to a prior measurement of the same operational statistics. An offset between a current measurement of the operational statistics and the prior measurement of the same operational statistics is determined. An average offset of the current measurement of the operational statistics and the prior measurement of the same operational statistics is determined for the subset of terminals. The average offset for the subset of terminals is merged with a previously determined peer group operational statistic. A signal validation of a terminal is performed using an updated deviation value.

  • Patent number: 9769773
    Abstract: A base station could establish maximum transmit power that the WCD should apply per carrier when serving the WCD on multiple carriers, with the base station considering the WCD's total power headroom and a delta of the WCD's uplink receive power per carrier. For instance, the base station could determine the WCD's total power headroom and could determine a receive power delta per carrier, the base station could effectively re-distribute the WCD's total power headroom among the carriers as adjustments to the maximum transmit power per carrier in accordance with a relative comparison of the receive power deltas on the carriers, the base station could further shift the adjustments to keep the sum of the WCD's maximum transmit power of the carriers in line with the WCD's maximum total transmit power, and the base station could direct the WCD to apply the shifted adjusted maximum transmit values.

  • Patent number: 9749970
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may coordinate power utilization across component carriers (CCs) with different transmission time interval (TTI) configurations. For example, the UE may reserve a portion of the transmit power for a CC with a reduced TTI length (e.g., an enhanced CC (eCC)). In other examples, the UE may dynamically allocate power between CCs with overlapping uplink periods. That is, the UE may borrow power allocated to one CC to transmit on an eCC. The UE may use a prioritization scheme to determine the transmit power for each CC. In some cases, the UE may send a power headroom report based on the power level of the eCC. The power headroom may be a virtual power headroom based on predicted eCC transmission power, or an actual power headroom based on uplink scheduling.

    Abstract: Disclosed herein are methods and systems for automatic creation of talkgroups based on received signal strength indicator (RSSI). In one embodiment, a first mobile radio broadcasts a talkgroup invite and receives responses from other mobile radios. The first mobile radio selects one or more of those other mobile radios based at least in part, for each received response, on one or both of (i) an invite-RSSI value included in the response and associated with receipt of the invite by the mobile radio from which the response was received and (ii) a response-RSSI value associated with receipt by the first mobile radio of the response. The first mobile radio establishes a talkgroup that includes itself and the one or more selected other mobile radios, and communicates as a participant in the established talkgroup.

  • Patent number: 9743363
    Abstract: Techniques are described for contention-based wireless communications channel access that may improve the likelihood that a contention procedure will pass and allow a device to transmit an uplink or downlink transmission using the contention-based channel. Various disclosed techniques may determine a transmit power for a subsequent transmission based on channel characteristics during one or more clear channel assessment (CCA) time durations. The transmit power may be selected to provide a CCA threshold that may increase the likelihood that a device will win contention for the channel during the CCA procedure.

  • Patent number: 9736794
    Abstract: The techniques described herein manage the transmission of reference signals on associated antennas of a cell site based on network conditions (e.g., the load of user data being transmitted via down-link (DL) transmissions). A reference signal includes control channel information that mobile devices are able to use to identify a particular cell and/or determine whether the particular cell is suitable for “camping” or “idling”. The techniques are configured to dynamically activate and/or de-activate various ones of multiple antennas, so that an inactive antenna does not broadcast reference signals. Rather, the techniques described herein configure a subset (e.g., one antenna) of a larger set of antennas (e.g., two antennas or four antennas) of a cell site to transmit reference signals so that the likelihood of control channel interference between neighboring cell sites is reduced.
