  • Patent number: 10587299
    Abstract: A user equipment includes at least one transmitter, a processor, and a memory. The transmitter transmits RF communication signals through at least one antenna. The processor executes program code in the memory to perform operations. The operations include identifying occurrences of a user being proximately located to the at least one antenna during transmissions. The operations determine duration of the transmissions while the user continues to be identified as being proximately located to the at least one antenna, and generate a cumulative RF exposure metric based on the determined durations of the transmissions. The operations responsively initiate a RF exposure remedial action responsive to the cumulative RF exposure metric satisfying a defined rule. The user terminal may thereby operate to avoid unnecessary RF radiation exposure to a user when that exposure would reach an excessive level.

  • Patent number: 10588094
    Abstract: For a cluster of cellular communication sites, the power consumption and data load of each site is measured over multiple time periods to determine an energy factor indicating the degree by which the power consumption of each site increases with increasing data load. The energy factors are then analyzed to determine coverage area sizes for the communications sites that will serve a given area while taking advantage of more efficient site to reduce overall power consumption of the cluster of sites. Transmission power levels are then adjusted at the sites to achieve these coverage area sizes.

  • Patent number: 10582459
    Abstract: A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.

  • Patent number: 10575261
    Abstract: A wireless device receives configuration parameters of: first cell(s) in a first frequency band; and second cell(s) in a second frequency band. A calculated total transmit power for signals is determined that comprise: a first SRS configured for transmission, during a time interval, via the first cell(s); and a second SRS configured for transmission, during the time interval, via the second cell(s). At least one of the first SRS or the second SRS is dropped or scaled based on an SRS transmit power priority of the first SRS and the second SRS when the calculated total transmit power exceeds a first value. The SRS transmit power priority is based on: a frequency band of the first cell(s) or the second cell(s); and whether the first SRS or the second SRS is configured for transmission in the first frequency band or the second frequency band.

  • Patent number: 10568052
    Abstract: Device-to-device (D2D) cross link power control systems and methods may be disclosed. For example, a device such as a UE or WTRU may determine whether it may have simultaneous transmissions where at least one of the transmissions may include a cross link transmission. The device may further determine whether a total transmit power of the simultaneous transmissions may exceed a maximum transmit power of the device. If the device may have simultaneous transmissions and such transmissions may exceed the maximum transmit power, the device may reallocate power based on a priority or priority setting. The device may further determine a maximum cross link power, a maximum device power, and a cross link transmit power level such that the device may further control the power for transmissions based thereon.

  • Patent number: 10554824
    Abstract: The transmit power level of a transceiver coupled to a digital subscriber line (DSL) line is reduced from a first transmit power level sufficient for the transceiver to continuously transmit data on the DSL line at a first bit rate to a second transmit power level below the first transmit power level sufficient for the transceiver to continuously transmit data on the DSL line at a second bit rate that is lower than the first bit rate. The reduction in transmit power is limited so that the change does not induce time-varying crosstalk sufficient to destabilize a nearby DSL line. While the transmit power level of the transceiver is reduced to the second transmit power level, the transceiver is suspended from transmitting data on the DSL line for repeated periods of time. Suspending the data transmission is controlled to avoid further time-varying crosstalk sufficient to destabilize the nearby DSL line.
