Abstract: Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.

Abstract: The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Abstract: Methods, systems, and devices for wireless communications are described for initiating beam training in systems that use beamformed wireless communications. A user equipment (UE) and a base station may establish communications using a first beam, and the UE may determine that a signal quality of the first beam is lower than a threshold value and that a beam training procedure is to be initiated. The UE may transmit a beam training request to initiate the beam training procedure, which may be transmitted as part of a bit sequence that is used to transmit uplink control information to the base station, such as with acknowledgment/negative-acknowledgment feedback, a scheduling request, or other uplink control information.

Abstract: The present disclosure relates to methods and apparatus for wireless communication of a first node. The apparatus can receive a first signal from a second node of one or more additional nodes, the first signal including at least one first timing reference. The apparatus can also determine a second timing reference quality of a second timing reference. The apparatus can also transmit a second signal to at least one node of the one or more additional nodes, the second signal including a second timing reference. Additionally, the apparatus can broadcast, to the one or more additional nodes, an indication of a second timing reference quality of the second timing reference. The apparatus can also receive an indication of a first timing reference quality. Moreover, the apparatus can adjust the indication of the quality of the at least one timing first reference from the second node.

Abstract: This disclosure provides systems, apparatus, methods, and computer-readable media for beam switching by a repeater node that forwards communications from one of a first node or a second node to the other of the first node or the second node. For example, after a change of position by the second node, the first node may provide the repeater node an instruction to perform a beam change operation to communicate with the second node. In some aspects, performing the beam change operation by the repeater node may improve reliability of wireless communications, such as by focusing signal energy in a particular direction. Further, a beam change delay time interval or a scheduling of the beam change delay time interval may be selected based on scheduling associated with other nodes, which may reduce a number of messages sent to the repeater node (such as by reducing instructions to change beam directions).

Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A scheduled entity (e.g., a user equipment (UE) or child integrated access backhaul (IAB) node) may observe a change in the downlink reception timing of downlink signals transmitted from a scheduling entity (e.g., a base station or parent IAB node). The scheduled entity may then autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. In addition, the scheduled entity may further maintain the same downlink transmission timing irrespective of the change in downlink reception timing.

Abstract: In some aspects, a node may configure whether a set of soft time resources is to be conditionally released or unconditionally released. The set of soft time resources may be configurable in a schedulable state or a non-schedulable state. The set of soft time resources may be schedulable subject to at most a directionality constraint when unconditionally released and, when conditionally released, being schedulable subject to: the directionality constraint and one or more conditions other than the directionality constraint if the set of soft resources is configured subject to the directionality constraint, or at least one of the directionality constraint or the one or more conditions other than the directionality constraint if the set of soft resources is not configured subject to the directionality constraint. The node may transmit a configuration that indicates whether the set of soft time resources is conditionally released or unconditionally released in the schedulable state.

Abstract: Methods, systems, and devices for wireless communications are described that support different, or adjusted, random access channel (RACH) preamble formats for efficient use of shared RACH time-frequency resources. The described techniques provide for assigning different RACH preamble formats to wireless devices that have a higher link budget, whereupon the devices may transmit the different RACH preamble using the link budget available to them in one or more RACH transmission opportunities in the shared RACH time-frequency resources. Such methods, systems, and devices may allow for more RACH transmission opportunities, as well as less interference between RACH transmissions. For example, wireless devices communicating over a backhaul network may have a higher link budget than wireless devices communicating over an access network. As such, RACH preambles transmitted by the wireless devices communicating over the backhaul network may be shorter than RACH preambles transmitted by the wireless devices communicating over the access network.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless node may transmit directional signals in a sweeping transmission pattern while receiving communications from a second wireless node. Another wireless node may then, during a listen-before-talk (LBT) procedure, receive one of the directional signals, and terminate a correspondence communication session to avoid potential interference. Additionally or alternatively, a wireless node may listen in directions in a sweeping receive pattern while transmitting to a second wireless node. While listening, the wireless node may detect a transmission from a third wireless node in a particular direction. The wireless node may then accordingly refrain from transmitting in that direction to avoid potential interference.
