A first network node has first antenna nodes located along a track and associated with a first cell. Some of them serve a first cell overlap region that overlaps a second cell overlap region of second antenna nodes connected to a second network node. Some first antenna nodes form downlink beams in a same direction with power levels controlled such that respective amounts of overlap between the downlink beams and respective power levels of the downlink beams jointly cause the first cell's overlap region to emulate a cell border for a user equipment travelling at high speed. Emulated cell border signal power is lower at locations closer to an emulated cell outer edge than at more distant locations. Emulated cell border length is sufficient to cause the travelling user equipment to be within the emulated cell border long enough to successfully perform a handover between the first and second cells.

A method for determining a transmit power level in an electronic device and the electronic device thereof are provided. The method includes activating an emergency mode, determining a transmit power level based on a condition, and transmitting an emergency message, including information associated with a request for rescue, with the determined transmit power level.

An access device of a communication network system calculates power estimation values for successive time slots of a communication channel based on measurement values for the successive time slots from a user equipment accessing the communication network system via the access device. The access device performs transmit power control based on the power estimation values. If a compressed mode is active for the user equipment, from use for the transmit power control, power estimation values or measurement values for predetermined time slots are excluded, which include no time slot or at least one time slot before a first time point T1 at which the user equipment has entered the compressed mode, at least one time slot after a second time point T2 at which the user equipment has returned from the compressed mode, and each time slot between the first time point T1 and the second time point T2.

Methods and apparatus for determining a transmit antenna gain and a spatial mode of a wireless device (100) are disclosed. The apparatus (100) includes a main receive antenna (112) associated with a first receive signal strength, a diversity receive antenna (114) associated with a second receive signal strength, and a transmit antenna (116). Each of the antennas (112, 114, and 116) is operatively coupled to a controller (102). The controller (102) determines (i) a difference between the first receive signal strength and the second receive signal strength, (ii) a correction factor based on the difference, and (iii) the transmit antenna gain based on the correction factor. In addition, the difference between the first receive signal strength and the second receive signal strength may be used, along with other sensor data (e.g., accelerometer), to estimate the spatial mode (e.g., orientation and hand grip) of the device (100). This spatial mode estimation may be then be used, among other things, to more accurately determine transmit antenna gain.

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.
