Published: with international search report (Art. 21(3)) (54) Title: UPLINK RESOURCES FOR BEAM RECOVERY (57) : Methods, systems, and devices for wireless communication are described. Uplink resources may be allocated for transmissions of beam recov- ery messages. For example, a user equipment (UE) communicating in a sys- tem that supports beamformed transmissions may receive a configuration for resources from a base station, where the resources may be used for beam recov- ery signaling. The UE may identify a beam failure on one or more active beams 405 used to communicate with the base station, and the UE may transmit a beam recovery message to the base station. In such cases, the beam recovery message may be transmitted according to the configuration received from the base station such that the beam recovery message is transmitted using the beam recovery resources. In some cases, the configuration may be received at the UE via radio resource control (RRC) signaling or via a system information broadcast from the base station. 425 Parton, feasuremenfs 435 f Be am Recovers , Messag Determin Transmit Beam Direction - 445 \ 440 400 Reference Signet FIG. 4
