Problems solved by technology

In the existing method for configuring authorization-free transmission resources, there will be an overlap between the previous authorization-free transmission resource group and the subsequent authorization-free transmission resource group, resulting in the determination of the authorization-free transmission of the terminal device. The complexity of the time unit where the resource is located is high

Abstract

The present application provides a method for determining time-domain resources for authorization-free transmission, including: a terminal device acquires a first time-domain period and a second time-domain period for authorization-free transmission resources, wherein the first time-domain period is P 1 time units, the second time domain period is P 2 time units, where P 1 Greater than or equal to P 2 ; The terminal device acquires the number k of authorization-free transmission resources in the first time domain period; The number k of resources determines the index of the time unit in which the license-free transmission resource used for the license-free transmission resides. It can support the non-overlapped allocation of authorization-free transmission resources for terminal equipment in two adjacent periods.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method and device for determining time domain resources for license-free transmission. Background technique [0002] Uplink license-free transmission is a come-and-go uplink data transmission method, that is, when data arrives, the terminal device does not need to send a scheduling request (Scheduling Request, SR) to the network device to request the network device to allocate uplink transmission resources, and wait for The network device sends the uplink data to the network device after sending the authorization information, but directly uses the pre-allocated resources and specified transmission parameters of the network device to send the uplink data to the network device. Compared with the traditional "request-grant"-based transmission method, the uplink authorization-free transmission method, which is an instant uplink data transmission method, has obvious ...
