CHANNEL STATE INFORMATION FEEDBACK METHOD AND APPARATUS IN WIRELESS COMMUNICATIONS SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18338947 titled 'CHANNEL STATE INFORMATION FEEDBACK METHOD AND APPARATUS IN WIRELESS COMMUNICATIONS SYSTEM
Simplified Explanation
The abstract describes a method for transmitting channel state information between a responder and an initiator in a wireless communication system. The responder receives a channel measurement signal from the initiator using one or more transmit antennas, and then sends a feedback frame to the initiator based on this signal. The feedback frame includes information indicating a subset of transmit antennas used by the initiator and the channel state information blocks of the channel between the subset of transmit antennas and the responder. The subset of transmit antennas is determined based on the antennas used to send the channel measurement signal.
- The method involves transmitting channel state information in a wireless communication system.
- The responder receives a channel measurement signal from the initiator using one or more transmit antennas.
- The responder sends a feedback frame to the initiator based on the channel measurement signal.
- The feedback frame includes information indicating a subset of transmit antennas used by the initiator.
- The feedback frame also includes channel state information blocks for the channel between the subset of transmit antennas and the responder.
- The subset of transmit antennas is determined based on the antennas used to send the channel measurement signal.
Potential Applications
- This method can be applied in various wireless communication systems, such as cellular networks, Wi-Fi networks, and satellite communication systems.
- It can be used in scenarios where channel state information needs to be transmitted between a responder and an initiator, such as in beamforming or MIMO (Multiple-Input Multiple-Output) systems.
Problems Solved
- The method solves the problem of efficiently transmitting channel state information between a responder and an initiator in a wireless communication system.
- It addresses the challenge of determining the subset of transmit antennas used by the initiator based on the channel measurement signal.
Benefits
- The method allows for accurate and efficient transmission of channel state information, enabling better communication performance in wireless systems.
- By providing information about the transmit antenna subset and channel state information blocks, the method enables effective beamforming and MIMO techniques, leading to improved signal quality and increased data rates.
- The method can enhance the overall capacity and reliability of wireless communication systems.
Original Abstract Submitted
A channel state information transmission method, where a responder receives a channel measurement signal sent by an initiator by using one or more transmit antennas, and the responder sends a feedback frame to the initiator based on the channel measurement signal. The feedback frame includes information used to indicate a transmit antenna subset of the initiator and one or more channel state information blocks of a channel between the corresponding transmit antenna subset of the initiator and the responder, where the transmit antenna subset is determined from one or more transmit antennas by using which a channel measurement signal is sent.
