Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may include a main radio and a low-power wake-up radio. While operating in a radio resource control (RRC) inactive state, the UE may use the low-power wake-up radio to monitor for signals. In some examples, the UE or a network entity may determine a relatively small amount of data (e.g., satisfying a threshold data volume) for communication between the UE and the network entity. The UE may receive a low-power synchronization signal via the low-power wake-up radio and may measure a signal strength or quality associated with the low-power synchronization signal. The UE may use this low-power synchronization signal measurement to determine whether to initiate a small data transmission (SDT) session for communicating the data. The UE may transmit an SDT initiation message if the low-power synchronization signal measurement satisfies a threshold value.

Abstract: Methods, systems, and devices for wireless communications are described in which a configuration of a wake-up signal (WUS), synchronization signal (SS), or both, may be selected based on one or more conditions at a user equipment (UE) that is to receive the signal.

The configuration may also indicate whether an associated signal is transmitted with or without Manchester coding. In some implementations, a UE may transmit an indication of a requested or preferred configuration for a WUS or SS, and may be configured in accordance with the requested configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving user equipment (UE) may broadcast messages containing inter-UE cooperation (IUC) information using multiple beams. The IUC information transmitted on each beam may be different for each beam of the receiving UE. For example, each IUC information may contain different preferred resources or non-preferred resources for the receiving UE to receive a transmission from a transmitting UE. The transmitting UE may receive a message containing IUC information from one of the beams of the receiving UE and transmit a signal using resources based on the IUC information contained in the received message. In some examples, the transmitting UE may transmit a channel busy ratio (CBR) request to a receiving UE. The CBR request may specify a transmission configuration indicator (TCI) state, spatial relation, spatial domain filter, or beam according to which the receiving UE is to measure the CBR.
