Abstract

A method to operate an access node of a wireless communication network is provided. A first frame may be provided including a first header and a first data block with first data for a first wireless terminal and a second wireless terminal. The header may include a first control field indicating a first idle period resource and a second control field indicating a second idle period resource, and the first and second idle period resources may be different. Transmission of the first frame to the first and second wireless terminals may be initiated. Responsive to receiving a notification message using the first idle period resource, a second frame may be provided including a second header and a second data block with second data for the second wireless terminal. Transmission of the second frame to the second wireless terminal may be initiated while deferring transmission to the first wireless terminal.
