Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described. Different periodicities may be dynamically selected when monitoring and transmitting signaling used for link management, where respective periodicities may be based on the quality of the link between devices. For instance, a first wireless device may use a first monitoring periodicity to monitor for signals transmitted from another wireless device. Upon determining that a link condition has changed (e.g., decreased or reached a threshold), the first wireless device may decrease its monitoring periodicity (and increase monitoring frequency) to detect signals transmitted by the other wireless device more frequently. In such cases, the other wireless device may likewise transmit its measurement signals more often (e.g., in accordance with a second periodicity) based on the link quality. The adjusted monitoring and transmission periodicities may provide additional occasions for the wireless device to detect signals from another device.

Abstract: Methods, systems, and devices for wireless communications are described. A codebook adaptation may be performed for a flexible user equipment (UEs) to determine a codebook for a physical configuration of the UE. For example, if the UE determines that the physical configuration does not correspond to a pre-loaded codebook in its memory, the UE may provide information about the physical configuration to a base station to determine a corresponding codebook. Additionally, the UE may request that the base station provide channel information to assist with the codebook determination. In some cases, this request may indicate for the base station to allocate a specific number of channel state information reference signal symbols that the UE can use for the codebook determination. Additionally or alternatively, the UE may generate the codebook internally and then signal to the base station a request for a beam refinement procedure with the generated codebook.
