Abstract

The invention discloses an information transmission method of a random access process and a terminal. The method comprises the following steps: acquiring a preset mapping relationship between a physical uplink shared channel (PUSCH) resource and a physical random access channel (PRACH) resource; and sending a random access message on a random access resource according to the preset mapping relationship, the random access resource comprising a PUSCH resource and a PRACH resource. According to the invention, the processing complexity of the network equipment can be reduced in the process of initiating random access, and the success rate of access can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission method and a terminal of a random access process. Background technique [0002] Fifth generation (5 th Generation, 5G) mobile communication system, or New Radio (NR) system, needs to adapt to diverse scenarios and business requirements. The main scenarios of NR system include enhanced Mobile Broadband (eMBB) communication, large-scale IoT (massive Machine Type Communications, mMTC) communication and ultra-reliable and ultra-low latency communication (Ultra-Reliable and Low Latency Communications, URLLC). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage. For services that occur periodically and have a fixed packet size, in order to reduce the overhead of downlink control signaling, network devices can use semi-static scheduling to continuously allocate cer...
