    Abstract: Methods, systems, and devices for updating beam-based communications are described. A base station may configure a user equipment (UE) with a set of beam management configurations, which may be used to modify (e.g., dynamically or periodically) beam-based communications. For example, the base station may indicate a beam configuration for utilization by the UE and the UE may switch to the indicated beam configuration or update a currently used beam configuration based on the indication. In another example, a set of beam configurations may be sequentially ordered, and the base station may indicate to the UE to use the next beam configuration in the sequence of beam configurations. The update to the beam configuration may be triggered based on a distance change (e.g., UE and base station getting closer or farther apart) or a reference signal measurement between the UE and the base station, among other factors.

    Abstract: A relay node supporting mobile terminal (MT) functionality and distributed unit (DU) functionality may receive a timing advance (TA) value for uplink synchronization associated with a timing alignment timer from a parent node. In some cases, the timing alignment timer may expire prior to the relay node receiving a next TA value. Upon expiration of the timing alignment timer, the relay node may initiate a second timer (e.g., a transition timer) associated with the transitioning of a DU entity of the relay node to a DU transition state. The DU transition state is associated with certain DU behavior for serving child nodes while the transition timer is active. Configuration of the DU transition state may be identified by the relay node, or received from a parent node. In cases where the transition timer expires prior to receiving a next TA value, the DU may declare a loss of uplink synchronization.

    Abstract: An intermediary base station supporting mobile terminal (MT) functionality and/or a user equipment (UE) may receive a time alignment (TA) command and associated timer value from one or more distributed units (DUs) and/or a central unit (CU) of a parent base station. The TA command and timer value may be based on an experienced or potential timer expiration associated with a TA of a communication link. The TA command may specify an updated TA value and a timer reset for scheduling communications on the communication link. In some examples, the TA command may be in response to a TA command request provided by the MT or UE on allocated resources or configurations indicated by the parent base station. In other cases, the TA command may be in response to a random access procedure on allocated resources or configurations indicated by the parent base station.

    Abstract: Methods, systems, and devices for wireless communications are described that provide a mechanism for a wireless node to identify resources that are controlled by a different wireless node in the wireless backhaul communications network and in some cases autonomously transmit certain transmissions using resources of the different wireless node. A first wireless node may receive signaling that indicates whether such transmissions may be autonomously transmitted via configuration information or a flag provided in signaling to the first wireless node. The first wireless node may in some cases determine that autonomous transmissions are enabled based on a type of communication or node that provides the information for the transmissions from the first wireless node. In some cases, a priority associated with the transmissions may be used to determine whether autonomous transmissions are enabled.
