Example information transmission methods, and apparatus are described. One example information transmission method includes determining resources for carrying N pieces of uplink control information (UCI) that partly overlap or completely overlap in time domain. The N pieces of UCI comprise 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. A priority of the beam channel quality information is lower than a priority of the ACK/NACK.

Information transmission method, terminal device, and access network device

An information transmission method, is provided, including, a terminal determines attribute information of uplink information based on a beam identifier, and sends the uplink information to a network side device based on the attribute information. After receiving the uplink information, the network side device determines the beam identifier based on the uplink information. In this process, the terminal implicitly indicates beam IDs of different selected beams by using attribute information of reported uplink information. Different beams correspond to different attribute information of the uplink information. In other words, each beam corresponds to specific attribute information of the uplink information. Implicitly indicating a beam ID to the network side device reduces LTE standardization complexity and reduces signaling overheads.

Information transmission method, terminal, and network side device

Embodiments of this application provide an uplink power control method and a terminal. The method includes: obtaining, by a terminal, a power control impact factor, where the power control impact factor includes at least one of the following: beamforming information, a subcarrier spacing, a time length, or a service type; determining, by the terminal, a transmit power of an uplink channel based on the power control impact factor; and sending, by the terminal, the uplink channel at the transmit power of the uplink channel. The embodiments can improve uplink power control precision.

Uplink power control method and terminal

Embodiments of this application disclose a reference signal transmission method, a message transmission method, a transmission resource determining method, and an apparatus. When a first device needs to transmit a reference signal, the first device may determine, from a slot and based on a time domain resource parameter of the reference signal, transmission resource information related to a transmission resource used to transmit the reference signal, where the transmission resource information may include a symbol location of the transmission resource in the slot and/or a space domain resource on a symbol in the transmission resource. Compared with a conventional manner in which a reference signal can be transmitted only at a fixed location, the transmission resource for transmitting the reference signal can be dynamically determined based on the time domain resource parameter of the reference signal.
