Abstract: This application discloses a communication method and apparatus. In the method, a terminal device receives first configuration information from an access network device, where the first configuration information is for configuring M configured grant (CG) resources to correspond N downlink reference signals. The M CG resources are used by the terminal device to send uplink information when the terminal device is in a non-connected state. The terminal device then receives first reconfiguration information from the access network device after the terminal device enters the non-connected state, where the first reconfiguration information is for updating downlink reference signals corresponding to some or all of the M CG resources.

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.
