Abstract
A method and apparatus for confirming delivery of group data to a plurality of radio communication devices in a wireless communication system. The wireless communication system includes a plurality of radio communication devices in communication with a sender. In operation, the sender sends group data to the plurality of radio communication devices and further determines a call hang time sufficient to contain a dedicated acknowledgment slot for each of the plurality of radio communication devices. The sender reserves an acknowledgment slot in the determined call hang time for each radio communication device and further sends an acknowledgment polling signal to each radio communication device, where the acknowledgment polling signal identifies the respective acknowledgment slot that is reserved for each radio communication device to acknowledge receipt of the group data. The sender accordingly receives an acknowledgment from the radio communication devices during its respective reserved acknowledgment slot.
