Abstract
Certain aspects of the present disclosure provide methods and apparatus for indicating a type of response for acknowledging a protocol data unit. One example method for wireless communications by a first apparatus generally includes transmitting a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a second apparatus and setting at least one bit in a PLCP header of the PPDU to indicate a type of response expected from the second apparatus responsive to the transmitted PPDU.
Claims32
An apparatus for wireless communications, comprising:
- a receiver configured to receive a physical layer convergence protocol (PLCP) protocol data unit (PPDU) which is not intended for the apparatus;
- and
- a processing system configured to determine a deferral time based on at least one bit in a PLCP header of the PPDU, wherein the at least one bit indicates a type of response to be sent by an intended recipient of the PPDU.
A method for wireless communications by an apparatus, comprising:
- receiving a physical layer convergence protocol (PLCP) protocol data unit (PPDU) which is not intended for the apparatus;
- and
- determining a deferral time based on at least one bit in a PLCP header of the PPDU, wherein the at least one bit indicates a type of response to be sent by an intended recipient of the PPDU.
An apparatus for wireless communications, comprising:
- means for receiving a physical layer convergence protocol (PLCP) protocol data unit (PPDU) which is not intended for the apparatus;
- and
- means for determining a deferral time based on at least one bit in a PLCP header of the PPDU, wherein the at least one bit indicates a type of response to be sent by an intended recipient of the PPDU.
A computer program product for wireless communications by an apparatus, comprising a computer-readable medium having instructions executable to:
- receive a physical layer convergence protocol (PLCP) protocol data unit (PPDU) which is not intended for the apparatus;
- and
- determine a deferral time based on at least one bit in a PLCP header of the PPDU, wherein the at least one bit indicates a type of response to be sent by an intended recipient of the PPDU.
A wireless station, comprising:
- at least one antenna;
- a receiver configured to receive, via the at least one antenna, a physical layer convergence protocol (PLCP) protocol data unit (PPDU) which is not intended for the wireless station;
- and
- a processing system configured to determine a deferral time based on at least one bit in a PLCP header of the PPDU, wherein the at least one bit indicates a type of response to be sent by an intended recipient of the PPDU.
