Adaptation of predetermined beam switching
Methods, systems, and devices for wireless communications are described. Communications by wireless devices may be modified when beam pair links (BPLs) experience decreased link quality. For example, a controlling wireless device may communicate with a secondary wireless device using a set of BPLs. The controlling and secondary wireless device may each cycle through the set of BPLs at respective times of a communication time period. Upon detecting one or more BPLs having a decreased link quality during a portion of the communication time period, the controlling wireless device may transmit a configuration modifying the communications. For instance, the modified communications may include replacing the one or more BPLs with different BPLs having a relatively higher link quality. In other cases, the modified communications may include using repeated transmissions during the portion of the communication time period or excluding the BPLs experiencing decreased link quality from the communication time period.
