Abstract

The invention provides a resource configuration method, an information sending method, a base station and a terminal. The resource configuration method is applied to a first base station to which a first cell belongs and comprises the steps of: acquiring configuration parameter information for optimizing the configuration of a physical random access channel resource of the first cell, wherein theconfiguration parameter information comprises resource configuration information about a MulteFire short physical random access channel (MF-sPRACH) of an adjacent cell of the first cell and / or randomaccess channel (RACH) information about the first cell; and configuring the physical random access channel resource of the first cell according to the configuration parameter information. The resourceconfiguration method, the information sending method, the base station and the terminal improve the preamble detection performance of the cell, and improve the success probability of cell random access.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a resource configuration method, an information sending method, a base station and a terminal. Background technique [0002] MulteFire (MF for short) is a new wireless access technology based on Long Term Evolution (LTE, Long Term Evolution), which can operate independently in unlicensed spectrum without using a licensed frequency band carrier. In order to fairly occupy unlicensed frequency band channels with other unlicensed frequency band devices (such as WiFi devices) and avoid mutual interference between unlicensed frequency band devices, the MulteFire physical layer introduces a WiFi-like carrier sense technology (LBT, Listen Before Talk )mechanism. When the base station or terminal detects that the unlicensed frequency band channel is occupied, that is, when LBT fails, it stops sending signals, and when it detects that the channel is idle, that is, when ...
