The NTN station transmits a communication signal at a second time and is received by the user equipment, which estimates a second downlink loss of the communication signal based on the first downlink loss and a power level of the communication signal. A first uplink loss is estimated based on the second downlink loss, and the user equipment adjusts a transmission power of its transmitter based on the first uplink loss.

  • Patent number: 11240762
    Abstract: There is provided a method for determining an uplink transmit power. The method may be performed by a user equipment (UE) and comprise: receiving information on an additional reduction value for an uplink transmission power and determining the uplink transmit power based on the additional reduction value. The additional reduction value may be used to reduce a cross link interference (CLI). The uplink transmit power may be determined within a lower bound and an upper bound. Based on that the uplink transmission may be performed in a frequency range 1 (FR1) for 5G, the additional reduction value is applied to one or both of the lower bound and the upper bound.

  • Patent number: 11240679
    Abstract: The techniques describe herein involve receiving, from a user device, captured network data associated with an altitude and analyzing the network data at a network node. The network node can determine a coverage index associated with the altitude and compare the coverage index with an aggregated coverage index to determine a network response. The network response can include deploying and/or modifying a network component associated with the altitude. Additionally, the network node can update a multidimensional coverage map based on the coverage index and/or the network response.

  • Patent number: 11228990
    Abstract: A wireless device transmits a first preamble via a first sub-band. The wireless device determines to perform a first preamble retransmission based on receiving no response to the first preamble. The wireless device selects, for the first preamble retransmission, a second sub-band. Based on the second sub-band being different from the first sub-band, the wireless device determines that a transmission power of the first preamble retransmission may be based on a same value of a power ramping counter used for transmitting the first preamble. The wireless device transmits, based on the transmission power, a second preamble for the first preamble retransmission via the second sub-band.

    Abstract: Methods, systems, and circuitries are provided to generate clock signals of different qualities in a device. A method includes determining whether the device is operating in a mid power mode or a high power mode. In response to determining that the device is operating in the mid power mode, oscillator circuitry is controlled to cause the oscillator circuitry to consume a lower amount of power, such that the oscillator circuitry generates a lower quality clock signal. In response to determining that the device is operating in the high power mode, the oscillator circuitry is controlled to cause the oscillator circuitry to consume a higher amount of power, such that the oscillator circuitry generates a higher quality clock signal. The lower amount of power and the higher amount of power are different from one another.
