1. A hybrid beamforming (HB) negotiation method comprising:
receiving, by an initiator from at least a first responder, at least one frame comprising capability information of the first responder,
wherein the at least one frame comprises a first subfield indicating polarization capability information of the first responder, a second subfield indicating whether HB is supported during Multi-User Multiple-Input and Multiple-Output (MU-MIMO) transmissions, and a third subfield indicating whether the HB is supported during Single-User Multiple-Input and Multiple-Output (SU-MIMO) transmissions,
wherein the second subfield comprises a first one-bit indicator to indicate whether the HB is supported during the MU-MIMO transmissions, and wherein the third subfield comprises a second, separate one-bit indicator to indicate whether the HB is supported during the SU-MIMO transmissions;
setting up, by the initiator, the HB in accordance with the capability information, for at least one upcoming Multiple-Input and Multiple-Output (MIMO) transmission between the initiator and at least the first responder, wherein the setting up of the HB for the at least one upcoming MIMO transmission between the initiator and at least the first responder includes transmitting, by the initiator to at least the first responder, another frame indicating an intention to use the HB in the at least one upcoming MIMO transmission; and
performing, by the initiator with at least the first responder, baseband HB training and feedback.
