Method of determining transmission rate of control response frame for acknowledging data receipt in wireless LAN
First Claim
1. A method of determining a transmission rate of a control response frame for acknowledging data receipt in a wireless network wherein at least one high throughput station and at least one legacy station with different data transmission capabilities respectively coexist, the method comprising:
- obtaining, by a receiving station, a modulation scheme and a coding rate of a data transmission frame of a high throughput format received from a transmitting high throughput station; and
determining, by the receiving station, the transmission rate of the control response frame based on a value corresponding to the obtained modulation scheme and the obtained coding rate among transmission parameters corresponding to a legacy format of a receiving station, wherein the obtained modulation scheme indicates 16-QAM and the obtained coding rate indicates ½

Abstract
A method is provided for determining a transmission rate of a control response frame for acknowledging data receipt in a wireless local area network. The method includes obtaining transmission parameters of a transmitting station from a data transmission frame received from the transmitting station, searching a receiving station for transmission parameters which correspond to the transmission parameters of the transmitting station, determining the transmission rate of the control response frame according to transmission parameters of the receiving station if the transmission parameters corresponding to the transmission parameters of the transmitting station are found in the receiving station, and determining a maximum rate among a set of basic transmission rates to be the transmission rate of the control response frame if the transmission parameters corresponding to the transmission parameters of the transmitting station are not found in the receiving station.
