Information transmission method and device

A method performed by a communication apparatus, comprising:

• receiving a slot format index from a network device, wherein the slot format index corresponds to a row in a slot format information table, and wherein each row in the slot format information table comprises positions, within a slot, of:
• uplink symbols, downlink symbols, and unknown symbols;
• and
• determining a slot format from the slot format information table based on the slot format index,
• wherein the slot format index corresponds to a row in the slot format information table that comprises a slot format of:
• DDXXXUUUDDDDDD,
• where:
• D represents a downlink symbol,
• U represents an uplink symbol, and
• X represents an unknown symbol.

A communication apparatus, comprising:

• a processor,
• a memory, and
• a communication interface;
• wherein the memory comprises computer-executable instructions that, when executed by the processor, cause the communication apparatus to carry out a method comprising:
• determining a slot format index for uplink-downlink transmission, wherein the slot format index corresponds to a row in a slot format information table, and wherein each row in the slot format information table comprises positions, within a slot, of uplink symbols, downlink symbols, and unknown symbols;
• and
• sending the slot format index to a terminal device through the communication interface,
• wherein the slot format index corresponds to a row in the slot format information table that comprises a slot format of:
• DDXXXUUUDDDDDD,
• where:
• D represents a downlink symbol,
• U represents an uplink symbol, and
• X represents an unknown symbol.
