Beam management for high-pathloss mode operations
Methods, systems, and devices for wireless communications are described. When operating in a high-pathloss mode, wireless devices in a network may transmit or receive downlink control information (DCI) that schedules a transmission time interval (TTI) for a physical shared channel (such as a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH)). A wireless device may determine one or more intervals that correspond to a periodic signal that collides with portions of the TTI. Based on the identified intervals, the wireless device may communicate over the physical shared channel during the TTI. In such cases, the TTI may overlap in time with the one or more intervals to allow communication of the periodic signal during the portions of the TTI. For instance, a periodic signal may be transmitted or received during each of the one or more intervals.
