For instance, a measurement request may be transmitted from a first device to a second device. This measurement request directs the second device to take one or more measurements of a wireless channel. Various characteristics for the one or more measurements may be included in the measurement request. For example, the measurement request may indicate at least one directional parameter and at least one timing parameter for the one or more measurements. In response to the request, the first device receives a measure report that includes measured values for each of the one or more measurements. ## Claims ### Claim 1 A device for collecting directional channel quality measurements from one or more station devices, comprising: at least one memory that stores computer-executable instructions; and at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to: generate a directional channel quality request frame comprising one or more measurement fields, wherein the one or more measurement fields indicate a device identification associated with a first station device, at least one measurement method, a measurement start time, and a measurement duration, and wherein the first station device is associated with a first period allocation; cause to send the directional channel quality request frame to the first station device, wherein the directional channel quality request frame further comprises a first indication of a first directional channel and indicates that the first station device is to perform the at least one measurement method to measure a quality of the first directional channel from the first station device to a second station device; identify a first directional channel quality response received from the first station device, the response comprising a measurement report, wherein the measurement report includes one or more measured values for the first period allocation, the one or more measured values associated with an average noise plus interference power indicator (ANIPI) or a received signal-to-noise indicator (RNSI);
