Embodiment Construction

[0182] figure 1 It is a frame diagram of a communication system involved in the embodiment of this application. Such as figure 1 As shown, the communication system includes: a network device 01 and a terminal device 02 . in,

[0183] Network device 01: may be the aforementioned base station, or various wireless access points, or may refer to a device in an access network that communicates with a terminal device through one or more sectors on an air interface. The base station can be used to convert received over-the-air frames to and from IP packets, acting as a router between the wireless terminal and the rest of the access network, which can include an Internet Protocol (IP) network. The base station may also coordinate attribute management for the air interface. For example, the base station may be a base transceiver station (BTS) in global system of mobile communication (GSM) or code division multiple access (CDMA), or it may be a wideband code division multiple access...

Abstract

An embodiment of the present application provides a data transmission method, a terminal device, and a network device. The method includes: the terminal device receives instruction information sent by the network device, and the instruction information is used to instruct the terminal device to send the first uplink transmission. The first time domain resource; the terminal device sends the first uplink transmission to the network device on the first time domain resource, and sends the second uplink transmission to the network device on the second time domain resource; the second The time domain resource is a time domain resource determined by the terminal device according to the first time domain resource, and the first time domain resource and the second time domain resource are continuous or discontinuous in time. According to the data transmission method, terminal device and network device provided by the embodiment of the present application, when the uplink transmission sent by the terminal device cannot occupy the full MCOT, the terminal device can continue to use the unoccupied MCOT to send other uplink transmissions, which can increase the resources of the MCOT utilization and channel utilization.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and in particular, to a data transmission method, terminal equipment, and network equipment. Background technique [0002] The licensed-assisted access using long term evolution (LAA-LTE) communication system can extend the available frequency spectrum to the 5GHz unlicensed frequency band through the carrier aggregation (CA) technology. With the assistance of licensed spectrum, terminal equipment and network equipment can transmit downlink transmission and uplink transmission on unlicensed spectrum. [0003] In order to share unlicensed frequency bands with other systems (such as communication systems of different operators, Wi-Fi networks, etc.), terminal devices in the LAA-LTE communication system use the listen-before-send method when using unlicensed frequency bands to send uplink transmissions. (listen-before-talk, LBT) channel access mechanism. That is, the termin...
