Acknowledgment management techniques for uplink multi-user transmissions

Abstract

Acknowledgment management techniques for UL MU transmissions are described. In various embodiments, an AP may observe a limit with respect to a number of TIDs for which corresponding A-MPDUs are to be acknowledged in a given immediate/compressed multi-user (MU) block ACK (BA). In some embodiments, the AP may indicate such a TID limit in a broadcast transmission, such as a beacon or management frame. In various other embodiments, the AP may indicate such a TID limit in a response for a capability request, such as a Probe Response, or in a specific allocation frame, such as a trigger frame, for all STAs participating in UL MU transmissions. In various embodiments, a single TID limit may be indicated that is understood to apply to each STA. In some other embodiments, the AP may indicate a respective TID limit for each of multiple STAs. Other embodiments are described and claimed.
