Abstract

The invention discloses an information transmission method, a terminal and network equipment, and the method comprises the steps: transmitting a first message of a random access process and filling information to the network equipment on a target transmission resource of a target transmission channel, wherein the first message and the filling information are subjected to frequency division multiplexing. According to the embodiment of the invention, the terminal jointly sends the first message and the filling information on the target transmission resource, so that the bandwidth utilization rate is further improved on the basis of ensuring the normal operation of the random access process on the authorized frequency band, the availability of idle transmission channels on the unauthorized frequency band can be ensured, and the normal operation of the random access process is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission method, a terminal and a network device. Background technique [0002] In a mobile communication system, processes such as initial access, system information acquisition, and link recovery can all be implemented through random access processes. Message 1 (message1, msg1) of the random access process in New Radio (NR) Both long and short sequences were introduced, 139 and 839, respectively. For the long sequence L=839, the subcarrier spacing (SubcarrierSpacing, SCS) of msg1 may be 1.25 kHz or 5 kHz. For the long sequence L=139, the subcarrier spacing of the preamble may be 15 / 30 / 60 / 120 / kHz. Physical Random Access Channel transmission occasion / Physical Random Access Channel occasion (RO) is defined as the time-frequency resources required to send a given format (format) msg1, under different subcarrier intervals, an RO occupies The band...
