1. A communication apparatus, comprising at least one processor and a computer-readable storage medium, wherein the storage medium stores instructions, and wherein the instructions, when executed by the at least one processor, cause the communication apparatus to:
receive a physical layer protocol data unit (PPDU) from a transmission opportunity (TXOP) holder, wherein the PPDU comprises a TXOP duration field, wherein the TXOP duration field consists of 7 bits, wherein the TXOP duration field indicates remaining time for using a channel by the TXOP holder, wherein the TXOP duration field comprises a first part which indicates a granularity, and a second part which indicates the remaining time using the granularity, wherein a first value of the first part indicates a first granularity, wherein a second value of the first part indicates a second granularity, wherein the first granularity is 8 μs, and wherein the second granularity is 128 μs; and
obtain a TXOP duration according to the TXOP duration field.
