Abstract
Circuits, methods, and apparatus that provide high-throughput control fields that, among other functions, provide efficient TXOP handoffs in wireless networks. A handoff may be made by setting one or more bits in a field in a QoS frame, such as the HT control or other appropriate field. Various conditions may be placed on a handoff by a granting station. For example, conditions specifying where a station receiving a TXOP handoff may send data, what the receiving station may do with any remaining TXOP, or what types of data may be transmitted by the receiving station may be imposed. These various conditions may be combined or omitted in any logic combination.
Claims28
An apparatus, comprising:
- means for receiving a data frame comprising a high-throughput control field, wherein the high-throughput control field includes information corresponding to a transmit opportunity transfer, wherein the transmit opportunity transfer includes an indication of a time interval for transmitting data;
- means for transmitting data in accordance with the transmit opportunity transfer;
- and
- means for determining a time remaining on the time interval for transmitting data, wherein the time remaining is based at least in part on the transmit opportunity transfer.
A wireless communication apparatus, comprising:
- at least one processor configured to:
- obtain a data frame that includes a high-throughput field, wherein the high-throughput field includes data corresponding to a transmit opportunity transfer, wherein the transmit opportunity transfer includes an indication of a time interval available for a data transmission;
- transmit information in accordance with the transmit opportunity transfer;
- and
- identify a time remaining on the time interval available for a data transmission, wherein the time remaining is based at least in part on the transmit opportunity transfer.
A computer program product, comprising:
- a computer-readable medium, comprising:
- code for causing at least one computer to receive a data frame comprising a high-throughput control field, wherein the high-throughput control field includes information corresponding to a transmit opportunity transfer, wherein the transmit opportunity transfer includes an indication of a time interval for transmitting data;
- code for causing the at least one computer to transmit data in accordance with the transmit opportunity transfer;
- and
- code for causing the at least one computer to determine a time remaining on the time interval for transmitting data, wherein the time remaining is based at least in part on the transmit opportunity transfer.
