Embodiment Construction

[0070] Below, some terms in the embodiments of the present invention are explained, so that those skilled in the art can understand:

[0071] Base station: also known as radio access network (Radio Access Network, RAN) equipment, is a device that connects terminals to a wireless network, which can be Global System of Mobile communication (GSM) or code division multiple Base Transceiver Station (BTS for short) in Code Division Multiple Access (CDMA for short), or a base station (NodeB, NB for short) in Wideband Code Division Multiple Access (WCDMA for short), or It is an evolved base station (Evolutional Node B, eNB or eNodeB for short) in Long Term Evolution (LTE for short), or a relay station or an access point, or a base station in a future 5G network, etc., and is not limited here.

[0072] Terminal: It can be a wireless terminal or a wired terminal. A wireless terminal can be a device that provides voice and / or other business data connectivity to users, a handheld device w...

Abstract

An embodiment of the present invention provides a data transmission method and device, the method comprising: a terminal receives uplink permission information sent by a base station, and determines a transmission interval according to the uplink permission information; after the terminal receives the uplink permission information, According to the transmission interval, transmit uplink data to the base station. It is realized that the base station can flexibly indicate the transmission interval, so that the terminal can flexibly determine the transmission interval according to the indication of the base station to transmit uplink data, thereby reducing waste of resources.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a data transmission method and device. Background technique [0002] Currently, an enhanced machine type communication (Enhanced Machine Type Communication, eMTC for short) technology is in a continuous research process. For half-duplex user equipment (User Equipment, referred to as UE), if eMTC is used to transmit data, when scheduling the transmission of uplink and downlink data, it is necessary to abide by the preset transmission regulations, that is, there will be certain constraints on the transmission time, for example: MTC physical The interval between the downlink assignment (DL Assignment) carried on the downlink control channel (MTC Physical DL Control Channel, referred to as MPDCCH) and the data carried on the physical uplink shared channel (Physical Uplink Shared Channel, referred to as PUSCH) corresponding to the downlink assignment is 3 shortest transmiss...
