Resource configuration method, random access method and device, base station and terminal

Abstract

The invention provides a resource allocation method, a random access method and device, a base station and a terminal. The method comprises the steps: configuring a mapping relation for scheduling request SR resource allocation information and physical random access channel PRACH resource allocation information; and / or configuring a mapping relationship for the logical channel and the PRACH resource configuration information; in the embodiments of the present invention, a base station configures a mapping relationship for SR resource configuration information / logical channel and PRACH resourceconfiguration information, according to the embodiment of the invention, the terminal performs random access by using the PRACH resource which is configured by the base station and has the mapping relationship with the SR resource configuration information / logical channel, and performs uplink data transmission on the uplink resource scheduled by the base station according to the corresponding time sequence relationship, so that the scheduling time delay can be reduced, and the call drop phenomenon can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method, a random access method, a device, a base station and a terminal. Background technique [0002] In NR (new air interface), when the user has uplink data to transmit, two methods can be used: 1) grant-free transmission (authorized transmission); 2) grant-based transmission (authorized transmission). Among them, the grant-based transmission refers to the execution of the scheduling request SR->uplink scheduling grant UL grant->buffer status reporting BSR->uplink scheduling grant UL grant process between the terminal UE and the base station eNB. In LTE (Long Term Evolution), the sending of the scheduling request SR is configured by the base station using Scheduling Request Config (scheduling request configuration information) and UE-specific (terminal specific information), mainly including time-frequency resources, maximum number...

Problems solved by technology

[0010] The purpose of the present invention is to provide a resource allocation method, a random access method, a device, a base station, and a terminal, so as to solve the problem in the prior art that the terminal has a large time delay from sending a scheduling request to accessing the base station, resulting in a high call drop rate. question
