Abstract: A waveform selection method and a device are disclosed. The method includes: obtaining an uplink signal sent by a terminal device; measuring, based on the obtained uplink signal N corresponding signal-to-noise ratios when the terminal device sends the uplink signal by using N ranks; calculating a first modulation and coding efficiency corresponding to each of the first signal-to-noise ratios; calculating, based on the first modulation and coding efficiency corresponding to each first signal-to-noise ratio, a second modulation and coding efficiency corresponding to each rank; selecting a target modulation and coding efficiency from second modulation and coding efficiencies corresponding to the N ranks; determining a target modulation and coding scheme; determining a target modulation scheme based on a target rank and the target modulation and coding scheme; and determining, based on the target modulation scheme and the target rank, a waveform type for the terminal device.

Abstract: A method includes: obtaining a first time domain resource allocation mode at a current moment; switching from the first time domain resource allocation mode to a second time domain resource allocation mode when a preset switching condition corresponding to switching from the first time domain resource allocation mode to the second time domain resource allocation mode is met; and allocating a time domain resource to a terminal device in the second time domain resource allocation mode.

Abstract: The embodiment of the present invention provides an apparatus and a method for adjusting a control parameter. The method in the embodiment of the present invention includes: obtaining, by a base station, random access information reported by multiple user equipment (UEs), where the random access information includes a contention conflict indication and a number of times of sending a preamble; collecting, by the base station, statistics on the random access information including contention conflict indication indicating a non-contention conflict; determining, by the base station, a first random access probability according to the random access information including contention conflict indication indicating a non-contention conflict; and adjusting, by the base station, a first random access power control parameter according to the first random access probability, where the first random access power control parameter is a preamble-initial-received-target-power.
