Resource configuration method, network device and terminal device

Abstract

An embodiment of the invention discloses a resource configuration method, network device and terminal device. The method includes that the network device determines a subcarrier mapping method of a random access leader sequence according to the number of subcarriers occupied by the random access leader sequence and the number of subcarriers of a physical random access channel; if the number of thesubcarriers occupied by the random access leader sequence and the number of the subcarriers of the physical random access channel and frequency domain resource of L physical random access channels having identical formats is a continuous resource, unoccupied subcarriers of M physical random access channels among the L physical random access channels are configured between the continuous resourceand subcarriers occupied by other physical channels or physical random access channels of other formats and the random access leader sequence is mapped to a position that is not configured with the unoccupied subcarriers of the continuous resource; the random access leader sequence sent according to the determining subcarrier mapping method by the terminal device is received. By adopting the method provided by the invention, interference between the physical random access channel and other physical channels or physical random access channels of other formats can be reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a resource configuration method, network equipment and terminal equipment. Background technique [0002] With the continuous development of communication network technology, users have put forward new requirements for network transmission speed, network system capacity and network transmission quality. The fifth-generation mobile communication technology (5th-Generation, 5G) has emerged and is constantly improving. The 5G air interface needs to support various services in the future, and various services may have different requirements. For example, enhanced Mobile Broadband (eMBB) services mainly require speed, coverage, transmission delay and mobility. The main requirements of Ultra-Reliable and Low Latency (URLLC) services are reliability, mobility and transmission delay. The main requirements of the massive Machine Type Communications (mMTC) service are th...

Problems solved by technology

[0003] In the existing 5G technical discussion, a physical random access channel (Physical Random Access Channel, PRACH) design scheme is proposed, in which, since the symbol length of the random access preamble (Preamble) is different from the symbol length of the data, The resource mapping method of each PRACH is the same. The subcarriers of the PRACH are adjacent to the subcarriers of the data channel, and there is no blank subcarrier between them. There is greater interference when the base station receives data and PRACH at the same time
