Abstract: A ranging method includes obtaining a first echo signal that is obtained after laser light emitted by a laser to a measured object is reflected by the measured object, determining that the first echo signal is a saturated echo signal, calculating an initial distance using a receiving moment of the first echo signal, determining a target distance compensation value corresponding to a saturation degree of the first echo signal, compensating, using the target distance compensation value and in a distance compensation manner, the initial distance, and setting a distance obtained after compensation as a measured distance between the measured object and the laser.

Abstract: In response to a user equipment (UE) sending data to a first network side device over a first channel and to a second network side device over a second channel, a method includes determining that the first channel separately overlaps the second channel and a third channel. The method further includes allocating, according to priorities of the first channel and the second channel, a first transmit power to the first subframe j and a second transmit power to the second subframe i. The first transmit power is less than or equal to a first power upper limit. A sum of the first transmit power and the second transmit power is less than or equal to a first threshold. A sum of third transmit power of the third subframe i+1 and the first power upper limit is less than or equal to a preset threshold.

Abstract: Embodiments of the present disclosure provide a backoff window adjustment method, and an apparatus. In downlink transmission, a base station obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the base station on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel. In uplink transmission, a user equipment (UE) obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the UE on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel.

Abstract: Embodiments of the present invention disclose a method and an apparatus for transmitting a synchronization signal. The method of the present invention includes: determining, by a first terminal, a D2D type, where the D2D type includes D2D discovery and D2D communication; and transmitting, by the first terminal, a synchronization signal according to the determined D2D type. Therefore, synchronization signals transmitted by terminals of different D2D types do not affect each other, avoiding that a second terminal detects and receives a synchronization signal that does not correspond to a D2D type of the second terminal and ensuring that user direct-connection communication can be performed correctly and efficiently.

Abstract: A method for determining a calibration parameter of a zero intermediate frequency radio receiver, and a zero intermediate frequency radio receiver are provided. The method includes: obtaining a plurality of sub-band training signals, where a sum of the plurality of sub-band training signals is a fullband training signal; determining a sub-band calibration parameter corresponding to each of the plurality of sub-band training signals; determining a fullband calibration signal according to the plurality of sub-band training signals and the sub-band calibration parameter corresponding to each of the plurality of sub-band training signals; and performing coefficient fitting on the fullband training signal and the fullband calibration signal, to determine a fullband calibration parameter. Because sub-band calibration parameters are obtained according to a plurality of different sub-band training signals, aliasing between an image signal and a training signal is reduced. Therefore, a speed and precision of determining a calibration parameter can be improved.
