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.

Claims14

Dependent claims

An IEEE 802.11 station (STA) comprising:

a transceiver configured to receive, from an access point (AP), a first frame that includes a first uplink transmission time (ULT) associated with the STA during which the STA is permitted to transmit uplink data to the AP;
a processor, coupled to the transceiver, configured to determine whether a wireless medium is available, and to transmit, along with the transceiver, uplink data to the AP when it is determined that the wireless medium is available, wherein on a condition that the processor and transmitter do not transmit uplink data during the first ULT associated with the STA, the processor and transceiver are configured to receive a second frame during the first ULT that includes a modified ULT associated the STA during which the STA is permitted to transmit uplink data to the AP;
and
the processor and the transceiver configured to transmit uplink data to the AP during the modified ULT associated with the STA.
