Triggering downlink traffic with timing indication

A method comprising:

• receiving a transmission block comprising a first portion indicating at least one target station, a second portion indicating a presence of downlink traffic, and a third portion indicating a transmission time;
• determining whether the at least one target station is capable of receiving data at the transmission time;
• causing transmission of an acknowledgement signal indicating whether the at least one target station is capable of receiving data at the transmission time;
• causing the at least one target station to enter a low power mode;
• causing the at least one target station to wake from the lower power mode at or before the transmission time;
• and
• receiving data at the transmission time.

An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:

• cause a transmission block to be provided with the transmission block comprising a first portion indicating at least one target station, a second portion indicating a presence of downlink traffic, and a third portion indicating a transmission time;
• receive of an acknowledgment signal from the at least one target station;
• and
• cause data to be provided to the at least one target station at the transmission time.
