Abstract: Example information transmission methods, terminal devices, and access network devices are described. One example information transmission method includes determining resources for carrying N pieces of uplink control information (UCI) partly overlap or completely overlap in time domain. The N pieces of UCI include at least one piece of beam channel quality information and at least one of a piece of channel state information or an acknowledgement (ACK)/a negative acknowledgement (NACK). A priority of the beam channel quality information is higher than a priority of the channel state information, and/or lower than a priority of the ACK/NACK.
