Abstract: An uplink transmission methods and apparatuses to reduce a probability that a collision between a user equipment (UE) and another UE occurs when the UE sends uplink data, thereby improving network performance are described. A plurality of different preamble signals are sent to a network device by a user equipment (UE). A feedback signal of the network device in response to the plurality of preamble signals is received by the UE. The feedback signal in response to each preamble signal carries a timing advance (TA) corresponding to the preamble signal. A valid TA is determined by the UE from the plurality of received TAs. A parameter used for uplink transmission is determined by the UE based on a feedback signal carrying the valid TA or a preamble signal corresponding to the valid TA. Uplink data are sent according to the parameter by the UE.

Abstract: A model application method and an apparatus are provided. The method includes: determining first information based on a received reference signal, where the first information includes data of m ports for the reference signal; and mapping the data of the m ports to an input of a first model based on a correspondence between the m ports and n ports in an input dimension of the first model, to obtain an output of the first model, where both m and n are integers greater than or equal to 1, and m and n are not equal. By using the method and the apparatus in this application, self-adaptation to a port of the reference signal can be implemented, and model storage and training overheads can be reduced.

Abstract: This application provides an uplink transmission resource determining method and an apparatus. The method includes: receiving first system information sent by a network device, where the first system information includes a first PUSCH resource configuration; determining whether a preset condition is met; receiving second system information sent by the network device when the preset condition is not met, where the second system information includes a second PUSCH resource configuration; and determining, based on the second PUSCH resource configuration, a parameter used for uplink transmission. In this way, a terminal may flexibly select the PUSCH resource configuration in the first system information or the PUSCH resource configuration in the second system information based on a requirement of the terminal. The second system information is received only when the preset condition is not met, to reduce information obtained by the terminal and reduce power consumption of the terminal.
