Communication method, terminal, and network device for repeating uplink control information to obtain data segment

A terminal, comprising

• a processor;
• and
• a transmitter,
• wherein the processor is configured to:
• repeat to-be-transmitted uplink control information for a quantity N of repetitions to obtain a first data segment, wherein N is a positive integer;
• determine an orthogonal cover code based on the quantity N of repetitions, wherein the orthogonal cover code is determined based on the quantity N of repetitions and a correspondence between the quantity N of repetitions and the orthogonal cover code;
• and
• multiply the first data segment by the orthogonal cover code to obtain a second data segment;
• and
• wherein the transmitter is configured to send the second data segment.

A network device, comprising:

• a receiver configured to receive a second data segment from a first terminal, wherein the second data segment is obtained based on processing a first data segment according to an orthogonal cover code, and wherein the first data segment is obtained based on repeating uplink control information of the first terminal for a quantity N of repetitions, wherein N is a positive integer;
• and
• a processor configured to:
• determine a conjugated orthogonal cover code based on N;
• multiply the conjugated orthogonal cover code by the second data segment to obtain the first data segment;
• and
• perform N rounds of deduplication processing on the first data segment to obtain the uplink control information of the first terminal.
