Abstract: Embodiments of this application provide a wireless communication method and an apparatus. The method includes: A first communication apparatus receives first information, where the first information indicates a determining threshold of a parameter in a first parameter set, and the first parameter set includes at least one of the following parameters: location information, delay information, a timing advance rate, a rate of the timing advance rate, a Doppler value, a Doppler rate, and remaining coverage time. The first communication apparatus determines, based on the first information, whether an access condition is met, and performs random access when the access condition is met. This avoids a random access failure in a current cell and re-access in a next cell due to random access performed when the condition is not met.

Abstract: In an information sharing method, a communication apparatus obtains first information sharing level of a first device, and sends first shared information corresponding to the first information sharing level to a second device. The apparatus obtains a second information sharing level of the first device, and sends second shared information corresponding to the second information sharing level to the second device. The second information sharing level is different from the first information sharing level, the second shared information is not exactly the same as the first shared information, and the first shared information and the second shared information are for model training.

Abstract: This application provides a method for processing a round trip delay, a related apparatus, and a readable storage medium, and pertains to the field of communications technologies. The method includes: receiving a delay quantization parameter of a common round trip delay (RTD), where the delay quantization parameter includes a first quantization parameter, and the first quantization parameter is used to indicate a height-related delay; and obtaining the common RTD based on the delay quantization parameter. The height-related delay is indicated by using the first quantization parameter, so that the common RTD is obtained based on the first quantization parameter.

Abstract: A terminal apparatus receives a parameter that is configured by a network apparatus and that is used to calculate an update period, where the update period is used to indicate time at which the terminal apparatus receives an uplink time-frequency synchronization parameter. The terminal apparatus receives an updated uplink time-frequency synchronization parameter based on the update period. The network apparatus configures the parameter for calculating the update period, so that the terminal apparatus can update the uplink time-frequency synchronization parameter in time.
