Abstract: Methods, systems, and devices for wireless communications are described. Some networks, such as over-deployed integrated access and backhaul (IAB) networks operating in millimeter wave (mmW) bands, may experience high energy consumption if all nodes in the network are fully active at all times. Power utilization modes may mitigate energy consumption by allowing nodes to operate at varying levels of activity. A power utilization mode may include a fully active mode or may drop one or more functions that a fully active node may support, or may support less extensive configurations associated with one or more supported functions, as compared to the configurations associated with a fully active node. Nodes may request information regarding one or more nodes, request a change in power utilizations modes for itself, indicate another node should change modes, or may receive an indication to change modes.

Abstract: Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an IAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.

Abstract: Aspects relate to establishing a signaling connection between a radio access network (RAN) node and a first scheduling entity. The RAN node may communicate in a dual connectivity (DC) mode of operation with the first scheduling entity (e.g., a secondary gNB) using a first radio access technology (RAT) and with a second scheduling entity (e.g., a master eNB) using a second RAT. The RAN node and the first scheduling entity may support sending information for a first signaling connection between the RAN node and the first scheduling entity over a second signaling connection through the second scheduling entity (e.g., when the second signaling connection is more reliable than the first signaling connection). To establish the second signaling connection, the RAN node and the first scheduling entity may signal support for the second signaling connection and exchange Internet Protocol information for the second signaling connection.

Abstract: A user equipment (UE) may transmit, to a primary cell, an indication of a capability to synchronize with a secondary cell based on measurements of the primary cell. A UE may estimate a propagation delay (tp) and an angle of arrival (AoA) of the secondary cell based on a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) transmitted by the primary cell. A UE may perform automatic gain control (AGC), fine timing synchronization, and fine frequency synchronization of the secondary cell based on a temporary aperiodic tracking reference signal (A-TRS) transmitted by the secondary cell. A UE may perform a receive beam sweep on a burst of a CSI-RS transmitted by the secondary cell, wherein a range of the receive beam sweep is based on the estimated AoA.

A base station provides information regarding what transmit beams are used to transmit different reference signal (RS) resources.

Abstract: Aspects of the present disclosure allow a UE to request, in an anchor carrier on one frequency band, a base station to configure and transmit A-TRS in an SSB-less secondary carrier on a different frequency band. The UE transmits, in a first cell served by the anchor carrier, a request for A-TRS. Based on the request, the UE receives, in a second cell lacking SSB transmissions served by the secondary carrier, the A-TRS based on the request. The base station may also control transmission of the A-TRS in the SSB-less secondary cell based on a timer derived from the request. Using the A-TRS, the UE may apply AGC and time/frequency tracking loop operations prior to receiving a PDSCH in the SSB-less secondary cell, thereby improving reception performance of downlink data transmissions in the secondary carrier. Thus, network energy savings provided by SSB-less secondary carriers may be obtained in inter-band CA.
