Abstract: Disclosed are a method and apparatus for determining an RA-RNTI. In the present application, a base station receives a random access preamble sent by a terminal; the base station determines an RA-RNTI according to a time-frequency resource occupied by the random access preamble, wherein the time-frequency resource is a time-frequency resource of an orthogonal frequency division multiplexing (OFDM) symbol level; and the base station sends a random access response message, wherein the random access response message comprises downlink control information allocated, by the base station, for the terminal, and the downlink control information is scrambled using the RA-RNTI. By means of the present application, an RA-RNTI can be determined during a random access process of an NR system.

Abstract: Disclosed are a data transmission method, device, and system. The method comprises: for the transmission of random access uplink data, according to the correspondence between preambles and data resources as described by a protocol, determining the data resource corresponding to the preamble in the uplink data transmission, different preambles corresponding to different data resources; transmitting the preamble and the uplink data that uses the determined data resource. In the embodiments of the present invention, a protocol describes the correspondence between preambles and data resources. For the transmission of random access uplink data, the data resource corresponding to the preamble in the uplink data transmission can be determined, and different preambles correspond to different data resources. Thus it can be ensured that different users use different data resources to bear uplink data, thereby enabling the data portion multiplexing for multiple users.
