Problems solved by technology

The transmission direction of the transmission resource may change at any time. When the license-free transmission resource and the transmission resource are in the same frequency band, and there is a transmission resource whose transmission direction is downlink within the time range where the license-free transmission resource is located, the license-free transmission may fail.

Embodiment Construction

[0157] The technical solution in this application will be described below with reference to the accompanying drawings.

[0158] figure 1 A communication system to which the present application is applicable is shown. The communication system includes network equipment and terminal equipment. The network equipment and the terminal equipment communicate through the wireless network. When the terminal equipment sends information, the wireless communication module of the terminal equipment can obtain the information bits to be sent to the network equipment through the channel. These information bits For example, it is the information bits generated by the processing module of the terminal device, received from other devices, or stored in the storage module of the terminal device.

[0159] In this application, a terminal device may be referred to as an access terminal, user equipment (UE), subscriber unit, subscriber station, mobile station, mobile station, remote station, remote ...

Abstract

The present application provides a method for sending uplink information, including: determining the authorization-free transmission resource for uplink transmission according to the transmission direction of the transmission resource and the preset authorization-free transmission resource, and the transmission resource includes the authorization-free transmission resource ; Send uplink information on the license-free transmission resources used for uplink transmission. According to this method, the license-free transmission resources used for uplink transmission may be a subset of the preset license-free transmission resources, or resources determined based on the positions of the preset license-free transmission resources, no matter which case is, The license-free transmission resources used for uplink transmission belong to the transmission resources whose transmission direction is uplink transmission, and the terminal device can determine the license-free transmission resources used for uplink transmission according to the transmission direction of the transmission resources and the preset license-free transmission resources, Therefore, the failure of the authorization-free transmission caused by the inconsistency between the preset transmission direction of the authorization-free transmission resource and the transmission direction of the transmission resource can be avoided.

Description

technical field [0001] The present application relates to the field of communication, and in particular to a method and device for sending and receiving uplink information in the field of wireless communication. Background technique [0002] The fifth generation (the 5 th generation, 5G) mobile communication system, transmission resources include transmission resources for uplink transmission and transmission resources for downlink transmission, for example, network devices can indicate which time slots in the transmission resources are used for uplink transmission and which Time slots are used for downlink transmission. [0003] Grant free is a transmission method proposed by the 5G mobile communication system. Terminal devices that transmit in a grant-free manner can directly send uplink information on preset grant-free transmission resources without waiting for resource scheduling information from network devices. Therefore, it has the characteristics of low delay. ...
