Abstract: Systems and methods are provided for coordinating power management for wireless communications devices in an independent basic service set (IBSS). An announcement traffic indication message (ATIM) coordinator receives address information for destination stations for which data is buffered for transmission at source stations. The ATIM coordinator sends an ATIM Indication frame at the end of an ATIM window, alerting any destination station to remain awake to receive buffered data. Source stations may enter power save mode during the ATIM window after transmitting the address information for the destination stations to the ATIM coordinator. Destination stations may enter power save mode after receiving a beacon at the start of the ATIM window. Source and destination stations may awaken at the end of the ATIM window to receive the ATIM Indication frame.

Abstract: The present disclosure provides techniques for rate adaptation under congestion and latency constraints. The approaches described herein focus on aspects of latency, reliability, and power consumption instead of the traditional aspect of throughput. In an example, a method for rate adaptation is disclosed. The method may include determining whether to transmit a new packet or a retry packet. The method may also include reducing a maximum rate for a rate search in response to determining to transmit the retry packet. The method may further include transmitting the retry packet based on the reduced maximum rate.
