发明名称 System and method for multicast/broadcast reliability enhancements over wireless LANs
摘要 A system comprises a communication engine for transmitting at least one groupcast packet to wireless stations on a wireless network; an ACK leader selection engine for identifying at least one of the wireless stations as a current ACK leader responsible for generating any ACK in response to the at least one groupcast packet, and for shifting the current ACK leader among a group of the wireless stations; and an ACK management engine for managing any ACK received from the current ACK leader.

主权项 1. A wireless network system comprising: an access point; and a plurality of wireless stations which communicate with the access point via a wireless network, wherein the access point includes: a communication engine for transmitting at least one groupcast packet to the wireless stations on the wireless network; an ACK leader selection engine for identifying a plurality of the wireless stations as a group of ACK leaders from the wireless stations, and for shifting the ACK leader among the group of the ACK leaders; and an ACK management engine for managing any ACK received from the ACK leader, wherein the at least one groupcast packet includes a plurality of groupcast packets, and the ACK includes a block-ACK; and wherein the ACK management engine instructs the communication engine to retransmit at least the groupcast packet identified in the block-ACK as having an error.
