RATE ADAPTATION FOR SDMA

摘要

A transmission parameter (430) for a link in a wireless network (100) is adapted for a current simultaneous transmission based on a loss parameter. The loss parameter is useable to determine an allocation for a wireless node (120d) of a plurality of wireless nodes (120d, 120e) participating in the simultaneous transmission. In some examples, the selected transmission parameter (430) and loss parameters for a previous transmission, along with the loss parameter for the current simultaneous transmission are used to determine the transmission parameter (410). In some embodiments, an access point (AP) (110) determines and communicates a loss parameter to a plurality of access terminals (AT) (120d, 120e). Each AT determines a modulation and coding scheme (MCS) based at least in part on the loss parameter. Each AT simultaneously transmits at least one data stream (160, 170) to the AP in accordance with the determined MCS. In some other embodiments, the transmission rate for simultaneous downlink communications (140, 150) is similarly adapted.
