Problems solved by technology

In the 3GPP RAN1 5G frame structure research, the mini-slot type has been added, so when sending data on the 5G unlicensed carrier, only the number of the start symbol of the sent data is sent to the terminal , at this time, the terminal does not know the type of frame structure that may be contained in the subframe, which increases the receiving complexity of the terminal side

Embodiment Construction

[0025] The embodiment of the invention discloses a subframe scheduling method and a base station, which are used to simplify the processing process of the terminal.

[0026] In order to better understand the subframe scheduling method and the base station disclosed in the embodiment of the present invention, the concept of the base station used in the embodiment of the present invention is firstly described below. At present, in the traditional LTE 4G network, the base station sends data based on a subframe. A subframe includes 14 symbols, and a subframe includes 2 slots, and each slot includes 7 symbols. , the symbol numbers in a subframe start from 0 to 13. see figure 1 , figure 1 It is a schematic diagram of a subframe disclosed by an embodiment of the present invention. like figure 1 As shown, symbols 1-6 are the first time slot, and symbols 7-13 are the second time slot. At present, in the LAA-LTE system, after the base station seizes the channel, it can only start s...

Abstract

A subframe scheduling method and a base station, the method is applied to the base station, including: when the base station seizes an unlicensed carrier, obtains the starting position of the preempted unlicensed carrier; determines the first serial number and the first subframe according to the starting position The type of the frame, the first number is the symbol number corresponding to the starting position used by the base station to send data, the first subframe is the subframe where the symbol corresponding to the first number is located; the type and the first number of the first subframe are sent to the terminal. The embodiment of the present invention can simplify the processing process of the terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a subframe scheduling method and a base station. Background technique [0002] The spectrum used by the wireless communication system includes a licensed spectrum (licensed spectrum) and an unlicensed spectrum (unlicensed spectrum). The licensed spectrum is a spectrum that can only be used by licensed users, and the unlicensed spectrum is a spectrum that can be used by any user. The carriers on the licensed spectrum are called licensed carriers, and the carriers on the unlicensed spectrum are called unlicensed carriers. Therefore, when the base station needs to use the unlicensed spectrum, it needs to seize the channel in a Listen Before Talk (LBT) manner. At present, in the Licensed-Assisted Access Using Long Term Evolution (LAA-LTE) system of Long Term Evolution, after the base station seizes the channel, it will send the number of the start symbol of the transm...
