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

Abstract

The embodiment of the present invention discloses a resource configuration method, network equipment, and terminal equipment. The method includes: the network equipment determines the random access preamble according to the number of subcarriers occupied by the random access preamble sequence and the number of subcarriers of the physical random access channel. The subcarrier mapping method of the sequence; if the number of subcarriers occupied by the former is smaller than that of the latter, and the frequency domain resources of L physical random access channels of the same format are continuous resources, then the M physical random access channels in L The vacant subcarriers of the access channel are configured between continuous resources and subcarriers occupied by other physical channels or physical random access channels of other formats, and the random access preamble is mapped to the position of unconfigured vacant subcarriers of continuous resources; receiving The random access preamble sent by the terminal device according to the determined subcarrier mapping manner. By adopting the present invention, the 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...
