Embodiment Construction

[0169] The embodiment of the present application discloses an uplink scheduling method, which can be applied in a wireless communication (such as LTE) system. For example, figure 2 It is a schematic diagram of the communication between the terminal and the base station in the LTE system, where the terminal and the base station perform data interaction through the licensed carrier. Corresponding to the licensed carrier, there is also an unlicensed spectrum in the space. The so-called unlicensed spectrum is It means that the spectrum has not been authorized by the relevant department to be occupied by a certain system, and other systems are not allowed to occupy it. For example, the frequency band of 5GHZ. At present, the carrier of this frequency band is mainly used for the transmission of signals of WIFI, Bluetooth, radar or medical systems. In order to expand the throughput of the LTE system, unlicensed carriers can be used to transmit signals of the LTE system. The purpose...

Abstract

The invention provides an uplink scheduling method as well as a terminal and a base station. The uplink scheduling method comprises the steps: detecting whether a non-authorized carrier is occupied or not by the terminal after the terminal receives a first uplink scheduling instruction transmitted by the base station, and executing the first uplink scheduling instruction by the terminal when the non-authorized carrier is not occupied, so only when the non-authorized carrier is idle, the terminal can execute the instruction for utilizing the non-authorized carrier to transmit the uplink data; or detecting whether the non-authorized carrier is occupied by virtue of the terminal to obtain a detection result, transmitting the detection result to the base station, transmitting a first uplink scheduling instruction to the terminal by the base station when the detection result indicates that the non-authorized carrier is not occupied, wherein the first uplink scheduling instruction is used for instructing the terminal to utilize the non-authorized carrier to transmit the uplink data, so only when the non-authorized carrier is idle, the base station can transmit the uplink scheduling instruction for utilizing the non-authorized carrier to transmit the uplink data, therefore, the failure in transmission of the uplink data caused by the occupation the non-authorized carrier can be avoided.

Description

technical field [0001] The present application relates to the communication field, and in particular to an uplink scheduling method and device. Background technique [0002] Currently, with the rapid development of mobile services, the capacity of the existing wireless spectrum allocated to mobile services cannot meet the requirements. In the 3GPP Rel-13 stage, a mechanism called licensed-assisted access (LAA) was introduced. In the LAA mechanism, the transmission of mobile communication can be carried on an unlicensed carrier, such as a 5GHz frequency band. These unlicensed carriers are currently mainly used by WiFi, Bluetooth, radar or medical systems. [0003] In the LTE system, for uplink transmission, the uplink scheduling instruction and the uplink data are transmitted at different subframe positions, and the interval between the subframe for transmitting the uplink scheduling instruction and the subframe for transmitting uplink data is predefined. [0004] Therefore...
