Abstract

The present invention discloses a random access transmission method and a terminal. The method includes: obtaining a demodulation reference signal DMRS sequence generation parameter of a physical uplink shared channel PUSCH; sending a random access message according to the DMRS sequence generation parameter; wherein, the random access The incoming messages correspond to PUSCH and PRACH. During the random access process, the terminal in the embodiment of the present invention sends a random access message on random access resources according to the DMRS sequence generation parameters of PUSCH. The PUSCH is demodulated to obtain corresponding random access messages, which improves the success rate of data detection, avoids unnecessary blind detection, and reduces the detection complexity of network equipment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a random access transmission method and a terminal. 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 certain resources for the tra...
