Method for uplink control information transmission, terminal device and access network device

Abstract

Provided are an uplink control information transmission method, device, and system. The method includes: when a first scheduling request and uplink information need to be sent in a target time unit, a terminal device simultaneously sends the uplink information and a second SR to an access network device on a physical resource in the target time unit. The terminal device uses multiple uplink logical channels for data transmission, the first SR is used for indicating at least one uplink logical channel containing available data in the multiple uplink logical channels, the second SR is used for indicating whether there is available uplink data on the multiple uplink logical channels, and parameters of at least two of the multiple uplink logical channels are different.

Dependencies are inferred from the claim text.
