Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an AP that requests a plurality of STAs to jointly enable and disable an MRP based on at least one of that each STA of the STAs has uplink traffic with the AP or that each STA of a subset of the STAs has a hidden node. The AP receives, from the STAs, information indicating a communication metric while jointly enabling or disabling the MRP. The AP determines, based on the received information indicating the communication metric, whether the joint enablement of the medium reserving procedure improves communication for the plurality of STAs. The AP requests the STAs to jointly enable the medium reserving procedure for subsequent communication when the joint enablement of the medium reserving procedure improves communication for the plurality of STAs.

Abstract: A method for monitoring feedback loop stability in a wireless repeater includes measuring a gain control metric in the feedback loop of the repeater periodically for a given time period where the gain control metric is indicative of a loop gain of the feedback loop of the repeater; and monitoring the magnitude of the gain control metric to determine the stability of the feedback loop of the repeater. In operation, a large magnitude of the gain control metric indicates instability in the feedback loop of the repeater.

Abstract: A method for estimating a feedback channel for a wireless repeater uses frequency domain channel estimation and uses a signal indicative of the amplified signal as a pilot signal. The channel estimation method generates a time domain feedback channel estimate from the frequency domain channel estimation and scales the time domain feedback channel estimate using scaling factors. In one embodiment, the scaling factors are function of a tap index and the block size of the frequency domain channel estimation.
