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 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;
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.

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.

11. 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 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; 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, the block acknowledgement frame reflective of decoding attempts of the plurality of frames. - View Dependent Claims (12)

13. 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; 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, the block acknowledgement frame reflective of decoding attempts of the plurality of frames by the receiving station. - View Dependent Claims (14)

15. A sharing station comprising:
-
a receiver configured to receive 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; 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 frame when the CTS frame corresponding to the RTS frame is not received within the specified time period. - View Dependent Claims (16, 17, 18, 19, 20, 21)
