METHOD OF OPERATION OF A WIRELESS COMMUNICATION SYSTEM

摘要

A method of operation (300) of a wireless communication system (100) includes: a client node sending (301) to the infrastructure node a message indicating that it intends to enter an unassociated state and a message requesting (303) the infrastructure node to store for the client node data of at least one multicast or broadcast transmission to be sent by the infrastructure node while the client node is in an unattached state; the client node entering (317) an unattached state and missing (319) at least one multicast or broadcast transmission while in the unattached state; the infrastructure node storing (323) for the client node while the client node is in the unattached state the data of the at least one missed multicast or broadcast transmission; and the infrastructure node sending (331) the stored data to the client node when the client node is in an associated state.
