    CPC classification number: H04W72/20

    Abstract: A resource mapping method and apparatus are described that reduce resource mapping complexity. The method includes an access network device obtaining resource mapping information of at least one terminal, and sending the resource mapping information to the at least one terminal respectively. The resource mapping information indicates a resource element RE to which each of the at least one terminal performs mapping in each RMB in a first resource mapping block RMB set. An RE to which a first terminal performs mapping in each RMB in the first RMB set is determined based on a first interleaved sequence, and the first interleaved sequence is determined based on a base sequence. The first terminal is any one of the at least one terminal, and the first RMB set includes at least one RMB.

    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.
