The present invention provides a detection method used for transmission bandwidth detection in multi-level transmission bandwidth assurance, including: detecting, by at least two transmission bandwidth detection units, a transmission bandwidth of a transmission link; where each transmission bandwidth assurance level in the multi-level transmission bandwidth assurance is corresponding to only one of the at least two transmission bandwidth detection units, and when the transmission link operates at a first transmission bandwidth assurance level, a first transmission bandwidth detection unit corresponding to the first transmission bandwidth assurance level detects the transmission bandwidth of the transmission link.

Detection method, device, and system

Embodiments of this application provide a method and an apparatus for setting a symbol in a communications system that uses a plurality of subcarrier spacings. The method includes: obtaining, by a terminal, a length of a reference blank symbol, where the length of the reference blank symbol is associated with a first subcarrier spacing, and the first subcarrier spacing is a minimum subcarrier spacing in the plurality of subcarrier spacings; and setting, by the terminal based on the length of the reference blank symbol and time domain information of the reference blank symbol, a blank symbol for a subcarrier corresponding to a second subcarrier spacing in the plurality of subcarrier spacings. According to the method and apparatus for setting a symbol provided in the embodiments of this application, when setting, based on the length of the reference symbol, a blank symbol in a subframe corresponding to a subcarrier used by the terminal, the terminal may set one or more complete symbols as blank symbols. This avoids a case in which a symbol cannot work normally because a part of the symbol is set as a blank symbol, thereby improving spectral efficiency of the system.

Method and apparatus for setting symbol

The embodiments of the present disclosure provide a power sharing method and a base station, wherein the method comprises the following steps of: according to a power demand of the communication systems of at least one mode among communication systems of different modes sharing a same power amplifier, determining whether to perform power sharing among communication systems of different modes (); if it is determined to perform power sharing among communication systems of different modes, adjusting an available power of communication systems of one or more modes therein (). According to the embodiments of the present disclosure, when it is determined to perform the power sharing according to the power demands, power sharing is performed among communication systems of different modes, thereby realizing dynamic and flexible power sharing among communication systems of at least two modes.

Embodiments of the present invention provide a method for converting mobile allocation and an upper control node of a base station. The method for converting mobile allocation includes: determining that at least one cell in cells controlled by an upper control node of a base station requires mobile allocation (MA) conversion; and instructing a base station to which the at least one cell belongs to convert, according to a time slot cluster, an MA occupied by a time slot of the at least one cell, where the time slot cluster is formed by the same time slots on different carrier frequencies. The embodiments of the invention may implement dynamic MA conversion according to actual conditions of a network, thereby guaranteeing the performance of the network, and improving the calling experience of users.
