Problems solved by technology

[0003] However, when a terminal device uses transmission resources in an unlicensed transmission area to send uplink data, different terminal devices may select the same transmission resource, resulting in conflicts between different terminal devices. For example, multiple terminal devices may Selecting identical or partially overlapping transmission resources in the authorized transmission area will lead to a higher probability of collision, and a higher probability of data transmission failure, which will reduce the reliability of data transmission

Abstract

Provided by the embodiments of the present application is a method for transmitting data, comprising: a network device sending first indication information to a terminal device in a first query area, the first indication information being used to indicate the distribution of transmission resources in an unauthorized transmission area corresponding to the first query area; the network device receiving data sent by the terminal device according to the first indication information in the unauthorized transmission area corresponding to the first query area, which thus helps improve the reliability of transmitting data.

Description

technical field [0001] The embodiments of the present application relate to the field of communications, and more specifically, to methods and devices for transmitting data in the field of communications. Background technique [0002] The future network system will introduce non-authorized (grant free, grant-free, grantless or without grant) mode to transmit data. In the non-authorized mode, the network device divides the terminal device into an unauthorized transmission area, and the terminal device uses the transmission resources in the non-authorized transmission area. Sending uplink data does not require the terminal device to implement the transmission of uplink data through a request, which can reduce delay and help save signaling overhead. [0003] However, when a terminal device uses transmission resources in an unlicensed transmission area to send uplink data, different terminal devices may select the same transmission resource, resulting in conflicts between differ...
