This disclosure describes systems, methods, and devices related to enhanced multiple-input multiple-output (MIMO) beam refinement protocol (BRP) transmit sector sweep (TXSS). A device may establish a first communication link using a first antenna transmit chain of one or more transmit chains of the initiator, wherein the one or more antenna transmit chains further comprise a second antenna transmit chain. The device may initiate a MIMO BRP TXSS over the one or more antenna transmit chains. The device may map a single space-time stream over the one or more antenna transmit chains. The device may cause to send, to a responder device, an enhanced directional multi-gigabit (EDMG) frame using spatial expansion based on the mapping of the single space-time stream. The device may identify a feedback frame from the responder device. The device may determine one or more antenna weight vectors (AWVs) to use in a MIMO phase of the MIMO beamforming training based on the feedback frame.
A device of an initiator for performing multiple-input multiple-output (MIMO) beamforming training the device comprising processing circuitry and storage, the processing circuitry coupled to storage, and the processing circuitry configured to:
A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
A method comprising:
