Wireless wake-up packet sending method and apparatus and wireless wake-up packet receiving method and apparatus

A wake-up packet receiving method, comprising:

• receiving, by a receiving apparatus, a wake-up packet (WUP);
• performing correlation processing on a sequence in the received WUP and a third sequence T stored in the receiving apparatus, and determining that the sequence in the WUP is a wake-up preamble sequence based on a correlation processing result, wherein the wake-up preamble sequence has a synchronization function;
• and
• determining that the sequence comprises N consecutive first sequences S, or that the sequence comprises a second sequence M, wherein the N consecutive first sequences S are used to indicate that a data rate used for a WUP payload of the WUP is a first value, wherein the second sequence M is used to indicate that a data rate used for the WUP payload of the WUP is a second value, wherein the second sequence M and a first sequence S are in a bit logical negation relationship, wherein N is an integer greater than or equal to 2, wherein T meets one of the following relationships:
• T=S*2−1, T=[N consecutive Ss]*2−1, T=M*2−1, or T=[N consecutive Ms]*2−1 and wherein:
• the first sequence S has a length of 32 bits, and the first sequence S is [1 0 0 0 1 0 0 1 0 1 1 1 0 1 0 0 0 1 0 1 1 1 0 0 1 1 0 0 0].

A wake-up packet sending apparatus, comprising:

• at least one processor;
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to obtain a wake-up packet (WUP), wherein the WUP comprises a preamble sequence having a synchronization function, and wherein:
• the preamble sequence comprises N consecutive first sequences S, wherein the N consecutive first sequences S are used to indicate that a data rate used for a WUP payload of the WUP is a first value;
• or
• the preamble sequence comprises a second sequence M, wherein the second sequence M is used to indicate that a data rate used for the WUP payload of the WUP is a second value, and wherein the second sequence M and a first sequence S are in a bit logical negation relationship;
• and
• a transceiver, the transceiver configured to send the WUP to wake up a main receiver of a receiving apparatus, wherein:
• the first sequence S has a length of 32 bits, and the first sequence S is [1 0 0 0 1 0 0 1 0 1 1 1 0 1 0 0 0 1 0 1 1 1 0 0 1 1 0 0 0].
