Abstract
Systems and techniques for managing channel reservation in a full-duplex wireless network. A transmitting node sends a media access control frame to a receiving node, including an integrity check field in a header of the frame. Upon performing an integrity check and determining that the media access control frame is addressed to itself, the receiving node sends a transmission so as to reserve the channel. If the receiving node has no data to send, the transmission may be an acknowledgement field, and if the receiving node has data to send, the transmission may be a media access control frame including an integrity check field in a header of the frame.
Claims20
An apparatus comprising:
- at least one processor;
- memory storing computer program code;
- wherein the computer program code is configured to, with the memory and the at least one processor, cause a receiving node of a wireless network to:
- upon detecting one or more fields in a header of a frame transmitted by a transmitting node of the wireless network, perform an integrity check on a received portion of the frame;
- and
- responsive to performing the integrity check and prior to receiving a complete transmission of the frame, perform an initial transmission to reserve a wireless network channel for use by the receiving node.
An apparatus comprising:
- at least one processor;
- memory storing computer program code;
- wherein the computer program code is configured to, with the memory and the at least one processor, cause a transmitting node of a wireless network to:
- initiate a transmission of a frame of the transmitting node, in a full-duplex operation in a license exempt spectrum, the frame including one or more fields in a header of the frame;
- and
- detecting, prior to completion of the transmission of the frame, a transmission initiated by a receiving node after an integrity check using the one or more fields.
A method comprising:
- upon detecting, at a receiving node of a wireless network, one or more fields in a header of a frame transmitted by a transmitting node of the wireless network, performing an integrity check on a received portion of the frame;
- and
- responsive to performing the integrity check and prior to receiving a complete transmission of the frame, performing an initial transmission to reserve a wireless network channel for use by the receiving node.
