Abstract
A method and apparatus may be used in wireless communications. The apparatus may be an access point (AP), and may transmit a power save frame. The power save frame may include one or more Uplink (UL) Transmission Times (ULT)s. The apparatus may determine that a station (STA) did not transmit during its respective ULT. The AP may transmit another power save frame. The other power save frame may include a modified ULT. The modified ULT may be for a STA that did not transmit during its respective ULT. The other power save frame may include an unmodified ULT. The unmodified ULT may be for a STA that did not transmit.
Claims42
A method for use in an access point (AP), the method comprising:
- transmitting, to a plurality of stations (STA)s, a first power save frame that includes a plurality of scheduled Uplink (UL) Transmission Times (ULT)s;
- determining that one of the plurality of STAs did not transmit during its respective ULT;
- and
- transmitting a second power save frame to the plurality of STAs, wherein the second power save frame includes a modified ULT for the STA that did not transmit during its respective ULT and an unmodified ULT for a STA with a ULT scheduled after the STA that did not transmit.
A station (STA) comprising:
- a transmitter;
- a receiver configured to receive a first power save frame that includes a plurality of Uplink (UL) Transmission Times (ULT)s, wherein one of the plurality of ULTs is a scheduled ULT for the STA;
- wherein, on a condition that the transmitter does not transmit during the scheduled ULT for the STA, the receiver is further configured to receive a second power save frame that includes a modified ULT for the STA and an unmodified ULT for a STA with a ULT scheduled after the STA;
- and
- wherein the transmitter is configured to transmit packet data based on the modified ULT.
An access point (AP) comprising:
- a receiver;
- a transmitter configured to transmit, to a plurality of stations (STA)s, a first power save frame that includes a plurality of Uplink (UL) Transmission Times (ULT)s;
- and
- a processor in communication with the receiver and the transmitter, the processor configured to determine that one of the plurality of STAs did not transmit during its respective ULT,
- wherein the transmitter is further configured to transmit a second power save frame that includes a modified ULT for the STA that did not transmit during its respective ULT and an unmodified ULT for a STA with a ULT scheduled after the STA that did not transmit.
A method for use in a station (STA), the method comprising:
- receiving a first power save frame that includes a plurality of scheduled Uplink (UL) Transmission Times (ULT)s, wherein one of the plurality of ULTs is a scheduled ULT for the STA;
- receiving, on a condition that the STA does not transmit during the scheduled ULT for the STA, a second power save frame that includes a modified ULT for the STA and an unmodified ULT for a STA with a ULT scheduled after the STA;
- and
- transmitting packet data based on the modified ULT.
