System and method for one-way traffic in wireless communications systems
First Claim
1. A method for operating a sharing station, the method comprising:
- receiving, by the sharing station, a request to send (RTS) frame on a wireless channel, wherein the RTS frame is not addressed to the sharing station, and wherein the RTS frame includes a transmit only indicator indicating that a transmitting station of the RTS frame will only transmit frames without receiving frames until expiration of a first time value in a first duration field of the RTS frame;
determining, by the sharing station, if a clear to send (CTS) frame corresponding to the RTS frame is received within a specified time period after receiving the RTS frame; and
transmitting, by the sharing station, a data frame when the CTS frame corresponding to the RTS frame is not received within the specified time period, wherein the data frame is transmitted prior to expiration of the first time value in the first duration field of the RTS frame.

Abstract
A method for operating a sharing station includes receiving, by the sharing station, a request to send (RTS) frame on a wireless channel, wherein the RTS frame is not addressed to the sharing station, and wherein the RTS frame including a transmit only indicator indicating that a transmitting station of the RTS frame will only transmit frames without receiving frames until expiration of a first time value in a first duration field of the RTS frame. The method also includes determining, by the sharing station, if a clear to send (CTS) frame corresponding to the RTS frame is received within a specified time period after receiving the RTS frame, and transmitting, by the sharing station, a frame when the CTS frame corresponding to the RTS frame is not received within the specified time period.

10. A method for operating a receiving station, the method comprising:
-
receiving, by the receiving station, a request to send (RTS) frame on a wireless channel, wherein the RTS frame is addressed to the receiving station, and wherein the RTS frame includes a transmit only indicator indicating that a transmitting station of the RTS frame will only transmit frames without receiving frames until expiration of a first time value in a first duration field of the RTS frame, wherein the transmit only indicator comprises at least one bit in a frame control field of the RTS frame, and wherein the frame control field is different from the first duration field; transmitting, by the receiving station, a clear to send (CTS) frame on the wireless channel; receiving, by the receiving station, a plurality of frames from the transmitting station of the RTS frame prior to expiration of the first time value in the first duration field of the RTS frame; receiving, by the receiving station, a block acknowledgement request frame from the transmitting station after expiration of the first time value in the first duration field of the RTS frame; and transmitting, by the receiving station, a block acknowledgement frame to the transmitting station, wherein the block acknowledgement frame is reflective of decoding attempts of the plurality of frames. - View Dependent Claims (11)

12. A method for operating a transmitting station, the method comprising:
-
transmitting, by the transmitting station, a request to send (RTS) frame on a wireless channel, wherein the RTS frame is addressed to a receiving station, and wherein the RTS frame including a transmit only indicator indicating that the transmitting station will only transmit frames without receiving frames until expiration of a first time value in a first duration field of the RTS frame, wherein the transmit only indicator comprises at least one bit in a frame control field of the RTS frame, and wherein the frame control field is different from the first duration field; receiving, by the transmitting station, a clear to send (CTS) frame from the receiving station; transmitting, by the transmitting station, a plurality of frames prior to expiration of the first time value in the first duration field of the RTS frame; transmitting, by the transmitting station, a block acknowledgement request frame after expiration of the first time value in the first duration field of the RTS frame; and receiving, by the transmitting station, a block acknowledgement frame from the receiving station, wherein the block acknowledgement frame is reflective of decoding attempts of the plurality of frames by the receiving station. - View Dependent Claims (13)

14. A sharing station comprising:
-
a receiver configured to receive a request to send (RTS) frame on a wireless channel, wherein the RTS frame is addressed to a station different from the sharing station, and wherein the RTS frame includes a transmit only indicator indicating that a transmitting station of the RTS frame will only transmit frames without receiving frames until expiration of a first time value in a first duration field of the RTS frame; a processor operatively coupled to the receiver, the processor configured to determine if a clear to send (CTS) frame corresponding to the RTS frame is received within a specified time period after receiving the RTS frame; and a transmitter operatively coupled to the processor, the transmitter configured to transmit a data frame when the CTS frame corresponding to the RTS frame is not received within the specified time period. - View Dependent Claims (15, 16, 17, 18, 19, 20)
