Problems solved by technology

[0006] However, the carrying capacity of PDCCH is limited, and may not provide enough bits to clearly indicate each RO resource; on the other hand, when completing a complete SSB-RO (or CSI-RS-RO) mapping required When there are few RO resources, if more time points are allocated, dozens or even hundreds of repeated mappings may be performed at these time points, resulting in only a few resources being available for other uplink signals. This configuration The mode has a great influence on uplink control and data transmission, so the possibility of such a configuration is very small, and if more than ten bits of PRACH resource indication information are introduced specifically for this configuration, it will lead to waste of bits

Abstract

The present application provides a non-contention random access resource configuration method and device, the method includes: based on a preset mapping relationship, sending target resource indication information to the terminal device; wherein the target resource indication information is used to determine the physical random access Incoming channel transmission opportunity RO resources, the target resource indication information includes: at least one of a physical random access control channel PRACH mask index and an RO resource index, and the preset mapping relationship is the value of the target resource indication information The corresponding relationship between scope and RO resources. Since the network device sends the target resource indication information with less content to the terminal device, the indication of the RO resource can be realized, so the bit overhead required for indicating the RO resource of the non-contention access process can be reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and more specifically relates to a method and device for configuring non-contention random access resources. Background technique [0002] In the Long Term Evolution (LTE) system, for the non-contention random access process, the network device sends to the terminal device a preamble index (preamble index) and a physical random access control channel (Physical Random Access Channel, PRACH) mask Index (mask index) information to instruct the terminal device to send the preamble (preamble) corresponding to the preamble index on the PRACH resource indicated by the PRACH mask index, and the network device often passes the physical downlink control channel (Physical Downlink ControlChannel , PDCCH) or radio resource control (Radio Resource Control, RRC) signaling to send the above information to the terminal device. [0003] In the new radio (New Radio, NR) system, the network devi...
