example 1

[0133] Example 1: The first sequence S contains [A(n) B(n)]. Specifically, the formula is expressed as follows:

[0134] S 1 (k) = [A(n) B(n)] (8)

[0135] Among them, n is the discrete expression of the time sampling point, which can be understood as a certain instant. The n in the subsequent formulas is the same as that described above, and will not be repeated here.

example 2

[0136] Example 2: The first sequence S contains continuous [A(n) B(n)]. Specifically, the formula is expressed as follows:

[0137] S 2 (k)=[A(n) B(n) A(n) B(n) ... A(n) B(n)], where [A(n) B(n)] is repeated a times, a> =1 (9)

example 3

[0138] Example 3: The first sequence S contains continuous A(n) and continuous B(n), wherein the number of A(n) and B(n) is the same; the formula is expressed as follows:

[0139] S 3 (k)=[A(n) A(n) ... A(n) B(n) B(n) ... B(n)], where A(n) and B(n) are repeated a times, a>=1 (10)

Abstract

A method for sending a wake-up packet, the sending device obtains the wake-up packet, the WUP includes a preamble sequence, and the preamble sequence is a first sequence S or a second sequence M; wherein the first sequence S is used to indicate The data rate adopted by the WUP is a first value, and the second sequence M is used to indicate that the data rate adopted by the WUP is a second value; wherein, the second sequence M and the first sequence S It is a bit logical NOT relationship; wherein, the number of 0s in the sequence in the preamble is the same as the number of 1s; wherein, the first sequence S, the second sequence M and the third sequence stored at the receiving side T is in accordance with the following relationship: T=S*2-1; and, the first sequence S is one of the sequences in each implementation manner.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more particularly, to a method and device for sending and receiving a wireless wake-up packet. Background technique: [0002] In short-distance wireless communication networks, such as IEEE802.11 series, that is, WLAN, or short-distance wireless communication networks such as Bluetooth, the feature of low power consumption has gradually aroused extensive discussions in the industry. Especially for the development requirements of the Internet of Things (IoT) based on the short-distance wireless communication technology, the feature of low power consumption is particularly important. Based on this situation, the application of Wake-up Receiver (WUR) can enhance the overall power consumption performance of the short-distance wireless network. [0003] The WUR is used to listen to and receive a wake-up packet (Wake-up Packet, WUP) for waking up the main circuit in a sleeping state w...
