SRS transmit power priority based on a cell type in a wireless device
A wireless device receives configuration parameters of: one or more first cells of a first cell type; and one or more second cells of a second cell type. A calculated total transmit power for a plurality of signals is determined. The plurality of signals comprise a first sounding reference signal (SRS) configured for transmission, during a time interval, via the one or more first cells; and a second SRS configured for transmission, during the time interval, via the one or more second cells. The wireless device drops a transmission of the first SRS or scales a transmission power of the first SRS, based on a SRS transmit power priority of the first SRS, when the calculated total transmit power exceeds a first value. The SRS transmit power priority is based on a cell type of the one or more first cells.
Low noise amplifier saturation mitigation
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling from a base station and may pass the signaling through one or more low noise amplifiers (LNAs) at a receiver of the UE. The UE may determine a saturation threshold at the one or more LNAs is exceeded. The UE may transmit an indication to the base station that the saturation threshold is exceeded. The base station may send additional signaling to the UE whose content, schedule, or configuration is responsive to the indication that the saturation threshold is exceeded. The UE may process the additional signaling using a digital linearizer at a receive chain of the UE. A base station may indicate an LNA saturation state to a UE in advance. The UE may respond to the indication (e.g., by setting LNA and digital linearizer states to accommodate predicted saturation).
POWER CONTROL FOR BIDIRECTIONAL SIDELINK
Power control for a bidirectional Sidelink (SL) is provided. Solutions proposed herein limit the Physical SL Feedback Channel (PSFCH) transmit power level to that of the power level used for Physical SL Shared Channel (PSSCH) so as to prohibit too high transmit power for the PSFCH. In addition, if the difference between the PSSCH and PSFCH exceeds a preconfigured threshold (e.g., the PSFCH is too low), a Receiver (Rx) User Equipment (UE) can take preventive actions that ensure sufficient quality over the PSFCH. In further embodiments, both UEs continuously maintain the estimated SL Path Loss (PL) and transmit a single SL Channel State Information Reference Signal (SCSI-RS), and associated measurement reports rather than triggering new SCSI-RS transmissions and measurement reports for each PSSCH and associated PSFCH channel per SL (e.g., PC5) connection.
FACILITATION OF INTERFACE MANAGEMENT IN DIRECTION OF EARTH STATIONS FOR 5G OR OTHER NEXT GENERATION NETWORK
This disclosure proposes a system to manage radio frequency (RF) interferences towards earth stations to solve needs of network providers. For example, user a user equipment that is close to an earth station can cause signal interference with the earth station as the user equipment is communicating with a base station. However, if the base station shares earth station location information with the user equipment, the user equipment can adjust its frequency and/or reduce its signal power to mitigate interference with the earth station. Alternatively, or in addition to, the base station can adjust its signal strength, and/or terminate a signal or resource that it is sending to the user equipment to prevent signal interference with the earth station.

Provided is a communication device configured to be capable of floating in the air, the communication device including a control unit that receives information regarding interference with a first communication device from a second communication device, the first communication device being not a communication partner, the second communication device being the communication partner, and controls transmission on the basis of the information regarding the interference and of an altitude of the communication device.
Method and system for determining transmission power of radios of a time division duplexing system
Techniques for determining power levels of radios, including a time domain duplexing (TDD) system, in shared frequency spectrum is provided. A TDD radio, of the TDD system, in a neighborhood having a largest interference contribution in the frequency spectrum at the point. Transmit power levels are determined for (a) the selected TDD radio, (b) other radios in the neighborhood that are not part of the TDD system, and (c) at least one radio in the TDD system that is not the TDD radio having the largest interference contribution in the frequency spectrum. Thus, interference margin may be fairly allocated to radios in neighborhood(s) about protection points.
Multi-transceiver wireless communication device capable of adequately adjusting parameters for Bluetooth transceiver
Disclosed is a wireless communication device including a wireless transceiver, a Bluetooth (BT) transceiver and a BT controller. The wireless transceiver supports at least one wireless communication standard (e.g., at least one of a series of IEEE 802.11 standards) and executes wireless communication via a wireless channel in a period of time. The BT transceiver executes BT communication via a plurality of BT channels successively in the period of time. The BT controller determines that a central-frequency difference between the wireless channel and a BT channel falls within a frequency interval of N predetermined frequency intervals and thereby controls the BT transceiver to use a set of parameters related to the frequency interval, wherein the set of parameters is one of N predetermined sets of parameters.
Method and apparatus for generating shared information for joint use of frequencies between radio stations
A method of generating shared information includes determining an attenuation effect on transmission power of a new radio station due to a reception mask of an existing radio station, calculating an interference effect of the existing radio station due to the new radio station using the attenuation effect, determining a protection domain of the existing radio station according to the interference effect, and generating shared information to be used by the new radio station based on the protection domain, wherein the protection domain is a domain in which a frequency available to the new radio station is restricted.
