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.
