The invention relates to a node address coding method of a wireless communication system, the wireless communication system and equipment. The method comprises the following steps: receiving a wake-upcode combination packet sent by a master node when a slave node is in a wake-up detection state, wherein the wake-up code combination packet comprises a first address code combination packet and a second address code combination packet, the first address code combination packet comprises a plurality of first address codes, the first address codes comprise a first lead code and a second lead code,and the second address code combination packet comprises a plurality of second address codes; enabling the slave node to detect the first lead code and the second lead code of a first address code inthe wake-up code combination packet sent by the master node; continuing to detect the spread spectrum sequence of the second address code when the slave node detects that both the first lead and thesecond lead are successfully detected; and enabling the slave node to enter a formal wake-up state from a wake-up detection state when the slave node detects that the spread spectrum sequence of the second address code is successfully detected, and receiving data sent by the master node. The method can save power consumption.
