Abstract
A method and apparatus for terminating frame reception in a wireless Local Area Network. A node receiving a frame transmitted on the common channel in a wireless Local Area Network determines the destination address of the frame. If the destination address indicates that the transmitted frame is not intended for that node, the node terminates reception of the frame for a time period at least as long as the time required to transmit the remainder of the transmitted frame. In a further embodiment, the time period can also include at least one Short Inter Frame Space and the time required to send an Acknowledgement frame.
Claims23
A method of processing a data frame at a node in a wireless Local Area Network, the method comprising:
- receiving a first part of a transmitted frame;
- identifying, within that first part of the transmitted frame, a frame destination address;
- and;
- terminating reception of a second part of the transmitted frame when it is determined that the frame destination address indicates that the transmitted frame is not intended for that node.
A wireless Local Area Network access node, comprising:
- a receiver adapted to receive a first part of a transmitted frame within the wireless Local Area Network;
- and
- a processor means configured to:
- (a) detect the frame destination address from the first part of the transmitted frame;
- and,
- (b) terminate reception of the second part of the frame when it is determined that the frame destination address indicates that the transmitted frame is not intended for that node.
A method of processing a data frame at a node in a wireless Local Area Network, the method comprising:
- receiving a first part of a transmitted frame;
- identifying, within that first part of the transmitted frame, a frame destination address;
- identifying, within the first part of the transmitted frame, a duration field, indicative of an expected duration of exchange of information related to the transmitted frame, after the transmission thereof;
- and,
- terminating reception of a second part of the transmitted frame when it is determined that the frame destination address indicates that the transmitted frame is not intended for that node and the duration field indicates the duration of exchange of information is less than a predetermined time.
