摘要： 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.

摘要： Embodiments of the present invention provide a wireless communications method, apparatus, and system. A terminal is provided. The terminal sets up a connection to a first base station, and stays in always connected mode. Therefore, when the terminal moves in a dense network, handovers of the first base station can be reduced. Further, when the terminal moves in the dense network, frequent signaling interaction is reduced, paging load in the entire network is reduced, and an end-to-end delay in service setup and transmission is reduced.
