Multi-user MIMO preference-indication signaling

Abstract:

An interface circuit in a recipient electronic device (such as a cellular telephone) may provide preference-indication information for an electronic device (such as an access point). Notably, the recipient electronic device may compute preference-indication information associated with the recipient electronic device, where the preference-indication information indicates whether the recipient electronic device prefers that the electronic device use downlink (DL) multi-user (MU) MIMO transmissions when communicating with the recipient electronic device. Then, the recipient electronic device may provide the preference-indication information in a packet or a frame associated with the electronic device. In some embodiments, the recipient electronic device determines a trigger event (such as measuring a motion indication), and the computing may be selectively performed based at least in part on the trigger event. Moreover, the preference-indication information may include additional information that was used by the recipient electronic device to compute the preference indication of the recipient electronic device.
