Uplink control information transmission method and apparatus

A method, comprising:

• receiving first indication information, wherein the first indication information comprises a parameter β and a parameter α;
• determining, based on the first indication information, first information;
• determining, based on the first information, a quantity of resources for sending uplink control information (UCI), wherein the first information comprises scheduling information, a ratio of a quantity of bits of the UCI to a quantity of bits of data, a first preset parameter, the parameter β, a quantity of available resources of a physical uplink shared channel (PUSCH), and the parameter α, wherein the parameter β is an offset of the UCI, and wherein the parameter α is configured by higher layer signaling and the parameter α is less than 1;
• and
• sending, based on the determined quantity of resources for sending the UCI, the UCI to a network device.

An apparatus, comprising:

• one or more processors;
• and
• one or more memories coupled to the one or more processors and storing programing instructions for execution by the one or more processors to:
• send first indication information to a terminal device, wherein the first indication information indicates a parameter β and a parameter α comprised in first information, and the first information further comprises scheduling information, a ratio of a quantity of bits of uplink control information (UCI) to a quantity of bits of data, a first preset parameter, and a quantity of available resources of a physical uplink shared channel (PUSCH), wherein the parameter β is an offset of the UCI, wherein the parameter α is configured by higher layer signaling and the parameter α is less than 1, and wherein the first information is used to determine a quantity of resources for the UCI;
• and
• receive, on the resources for the UCI, the UCI from the terminal device.

A system, the system comprising a network device and a terminal device, wherein the network device is configured to:

• send first indication information to the terminal device, wherein the first indication information indicates a parameter β and a parameter α comprised in first information, and the first information further comprises scheduling information, a ratio of a quantity of bits of uplink control information (UCI) to a quantity of bits of data, a first preset parameter, and a quantity of available resources of a physical uplink shared channel (PUSCH), wherein the parameter β is an offset of the UCI, wherein the parameter α is configured by higher layer signaling and the parameter α is less than 1;
• the terminal device is configured to:
• receive the first indication information;
• determine, based on the first information, a quantity of resources for the UCI;
• and
• send, based on the quantity of the resources, the UCI to the network device;
• and
• the network device is further configured to:
• receive the UCI from the terminal device.
