Embodiment Construction

[0083] 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: network equipment and terminal equipment. The communication system may be an LTE communication system, or other future communication systems, such as a 5G communication system, etc., which is not limited herein.

[0084] Network device: It can be a device that connects terminal devices to a wireless network. The device may be a 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 terminal device 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...

Abstract

The embodiment of the invention provides an information transmission method and device, and the method comprises the steps that network equipment determines time slot format information which is usedfor indicating the position of an uplink symbol, the position of a downlink symbol and the position of an unknown symbol in a time slot; The network devicesends the time slot format information, the terminal device receives the time slot format information from the network equipment, and the time slot format information is used for indicating the position of an uplink symbol, the position of a downlink symbol and the position of an unknown symbol in a time slot; And the terminal device determines a time slot format according to the time slot format information. The uplink-downlink ratio provided by the invention can meet the requirements of low-delay and high-reliability scenes.

Description

[0001] This application claims the priority of a Chinese patent application with application number 201711147522.4 and application title "Information Transmission Method and Device" filed with the China Patent Office on November 17, 2017, the entire contents of which are incorporated herein by reference. technical field [0002] The present application relates to the technical field of communications, and in particular to an information transmission method and device. Background technique [0003] The 5th Generation Mobile Communication (5G) New Radio Access Technology (NR) has received extensive attention and research in 3GPP and other international standardization organizations. 5G mobile communication systems Some application scenarios (such as Ultra-reliable and low-latency communications (URLLC)) have higher requirements, such as high reliability and low latency. [0004] In the existing Long Term Evolution (LTE) system, two different duplex modes, Frequency Division Du...
