Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a failure event for a beam or a link, between the UE and a base station, is occurring or will occur, and transmit a message to the base station indicating that the UE is refraining from performing a recovery procedure for the beam or a link for a time duration. Numerous other aspects are provided.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This Patent Application claims priority to U.S. Provisional Patent Application No. 62/985,830, filed on March 5, 2020, entitled "SUSPENSION OF BEAM OR LINK RECOVERY FOR A FAILURE EVENT," and U.S. Nonprovisional Patent Application No. 17/249,394, filed on March 1, 2021, entitled "SUSPENSION OF BEAM OR LINK RECOVERY FOR A FAILURE EVENT," which are hereby expressly incorporated by reference herein. INTRODUCTION Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for suspending beam or link recovery. Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). A wireless network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A UE may communicate with a BS via the downlink and uplink. "Downlink" or "forward link" refers to the communication link from the BS to the UE, and "uplink" or "reverse link" refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a new radio (NR) BS, a 5G Node B, or the like. The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. NR, which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies. SUMMARY In some aspects, a method of wireless communication performed by a user equipment (UE) may include determining that a failure event for a beam or a link, between the UE and a base station, is occurring or will occur. The method may include transmitting a message to the base station indicating that the UE is refraining from performing a recovery procedure for the beam or the link for a time duration. In some aspects, a method of wireless communication performed by a base station may include receiving a message from a UE indicating that the UE has refrained or will refrain from performing a recovery procedure for a time duration after a failure event for a beam or a link. The method may include refraining from abandoning or reassigning the beam or the link for the time duration. In some aspects, a method of wireless communication performed by UE may include determining that one or more failure events for a beam or a link, between the UE and a base station, have occurred. The method may include transmitting a message, to the base station, indicating information associated with the one or more failure events. In some aspects, a method of wireless communication performed by a base station may include receiving a message from a UE indicating information associated with one or more failure events that occurred for a beam or a link between the UE and the base station. The method may include reconfiguring a recovery procedure for the UE based at least in part on the information associated with the one or more failure events. In some aspects, a UE for wireless communication includes a memory and one o
