COLLISION DETECTION AND BACKOFF WINDOW ADAPTATION FOR MULTIUSER MIMO TRANSMISSION |
摘要 |
Certain aspects of the present disclosure generally apply to a wireless local area network (WLAN) where an access point (AP) has data to send to multiple stations (STAs). By using the Downlink Spatial Division Multiple Access (DL-SDMA) technique, the AP may send data at the same time towards multiple STAs. Certain aspects of the present disclosure provide techniques and apparatuses for detecting that a multiuser multiple-input multiple-output (MU-MIMO) transmission has suffered a collision and to adapting a contention window (CW) size for a backoff counter applied to a subsequent MU-MIMO transmission. |
