Start frame for distributed MIMO

摘要

Embodiments of the present disclosure generally relate to communication, and more specifically to distributed multiple-input multiple-output (MIMO) systems. For certain aspects, methods and apparatus are provided for transmitting a start frame containing information regarding parallel MIMO transmissions in a transmit opportunity and transmitting one or more parallel MIMO streams in accordance with the information contained in the start frame. For certain aspects, methods and apparatus are provided for receiving a start frame containing information regarding parallel MIMO transmissions in a transmit opportunity and transmitting one or more parallel MIMO streams in accordance with the information contained in the start frame. For certain aspects, methods and apparatus are provided for receiving a start frame containing information regarding parallel MIMO transmissions in a transmit opportunity and receiving one or more parallel MIMO streams in accordance with the information contained in the start frame.

主权项

1. A method for wireless communications, comprising:
transmitting, from an apparatus, a start frame including information regarding parallel multiple-input multiple-output (MIMO) transmissions in a transmit opportunity, wherein the information indicates a starting time to synchronize the start of the MIMO transmissions among multiple apparatuses, wherein the information specifies a transmission power requirement for each transmitter among the multiple apparatuses, and wherein the transmission power requirement for each transmitter includes a reduction of transmission power for at least one transmitter; and transmitting one or more MIMO streams in accordance with the information contained in the start frame.
