摘要： 5G and especially 6G are intended to accommodate high-speed mobile user devices and access points such as wireless devices on trains and airplanes, while retaining enhanced mobile broadband eMBB service. Therefore, new resource-efficient, low-complexity procedures are needed for measuring and correcting the Doppler frequency shift. To assist user devices, a base station or access point can periodically broadcast a current geographical location of the base station or access point in a localization message. In some embodiments, the geographical location data can be included in a periodically broadcast system information message, such as unused space of a SSB (synchronization signal block) message or an SIB1 (first system information block) message. User devices can then determine a vector toward the base station or access point relative to the user device location and velocity, and thereby calculate a Doppler correction without a frequency scan or other overhead, according to some embodiments.

摘要： This disclosure relates to a method for reducing power consumption of a first device for use in a wireless communication system. The first device receives a signal within a first reference sub-frame of a radio channel. The device determines whether to use the signal for obtaining channel state information to be reported to a second device within a reporting sub-frame, or whether to receive and use a second signal within a second reference sub-frame of the radio channel for obtaining channel state information to be reported to the second device within said predetermined later sub-frame. Based on this determination, the first device reports channel state information obtained based on the signal received within said first reference sub-frame or said second signal within said second reference sub-frame to the second device within said reporting sub-frame.

摘要： Apparatus and methods are disclosed for adaptive transmit power control for vehicle communication. An example disclosed vehicle includes a driving assistance unit and a communication module. The driving assistance unit determines an expected speed of target vehicles in the vicinity of the vehicle. The communication module determines a message type of a message received from a subsystem of the vehicle. Additionally, the communication module broadcasts the message at a power level. The power level is based on the message type and the expected speed of target vehicles.

摘要： An electronic device may include wireless circuitry that is configured to transmit wireless signals during operation. A maximum transmit power level may be established that serves as a cap on how much power is transmitted from the electronic device. Adjustments may be made to the maximum transmit power level in real time based on sensor signals and other information on the operating state of the electronic device. The sensor signals may include motion signals from an accelerometer. The sensor signals may also include ultrasonic sound detected by a microphone. Device orientation data may be used by the device to select whether to measure the ultrasonic sound using a front facing or rear facing microphone. Maximum transmit power level may also be adjusted based on whether or not sound is playing through an ear speaker in the device.

摘要： Methods and apparatus for identifying a subscriber station which is in motion, determining a mobility metric indicative of a level of mobility of the subscriber station and varying or updating one or more operating parameters based on the mobility metric. An apparatus can determine a measure of mobility based on one or a combination of a plurality of factors, such as variations in signal strength, variations in a channel estimate, or variations in phase or frequency of a particular signal or signal component. The one or more measures of mobility can be combined to form a single measure of mobility, the measure of mobility can be quantized to a predetermined number of mobility levels and one or more operating parameters can be varied or adjusted based on the mobility level.
