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 invention provides a non-competitive random access resource configuration method and equipment, and the method comprises the steps: transmitting target resource indication information to a terminal device based on a preset mapping relation; wherein the target resource indication information is used for determining a physical random access channel transmission opportunity RO resource; wherein the target resource indication information comprises at least one of a physical random access control channel (PRACH) mask index and a reverse osmosis (RO) resource index, and the preset mapping relationship is a corresponding relationship between a value range of the target resource indication information and RO resources. Since the indication of the RO resource can be realized by sending the target resource indication information with less content to the terminal device by the network device, the bit overhead required for indicating the RO resource in the non-competitive access process can bereduced.

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...
