In the drawings, like numerals reference similar elements.įIG. Some features are shown by way of example, and not by limitation, in the accompanying drawings. These and other features and advantages are described in greater detail below. If a beam failure recovery request is repeated, the wireless device may send the second request using a new beam a threshold distance, in time and/or frequency, from a beam used for the prior request. The wireless device may perform beam failure recovery on other serving beams that have not failed. The wireless device may determine if only a subset of serving beams have failed. A wireless device may detect a beam failure (or any other wireless/communication resource failure). Systems, apparatuses, and methods are described for communications associated with beam failure recovery. The summary is not an extensive overview and is not intended to identify key or critical elements. The following summary presents a simplified summary of certain features. It is desired to improve wireless communications, including to improve reconnections, without adversely increasing signaling overhead and/or decreasing spectral efficiency. Interference that may cause an initial disruption, such as disconnection, may also prevent a reconnection. In wireless communications, communication disruptions may occur. The above-reference applications are hereby incorporated by reference in their entireties. ![]() 10,863,570, which claims the benefit of U.S. ![]() 15, 2019, which is a continuation of U.S. This application is a continuation of U.S. Patent Description CROSS-REFERENCE TO RELATED APPLICATIONS
