Abstract: Aspects described herein relate to receiving, by a mobile termination (MT) function of an integrated access and backhaul (IAB) node, a first indication to migrate from a first IAB donor node associated with a first cell group and a first central unit (CU) to a second IAB donor node associated with a second cell group and a second CU, performing, by the IAB node and based at least in part on receiving the first indication, a first random access procedure to connect to the second cell group associated with the second IAB donor node, establishing, by the IAB node in addition to a first distributed unit (DU) function of the IAB node that serves a third cell group and based on performing the first random access procedure, a second DU function that serves a fourth cell group.

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.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on synchronization signal blocks (SSB) in a network (e.g., an Integrated Access and Backhaul (IAB) network. In some cases, a node determines resources used for periodic SSB transmissions by at least one parent node of the network, uses the determined resources to perform SSB-based interference measurements, and communicates with at least one of the parent node, a central unit (CU), or another node of the network based on the SSB-based interference measurements.

Abstract: Certain aspects of the present disclosure provide techniques for beam refinement. A base station provides information regarding what transmit beams are used to transmit different reference signal (RS) resources. In some cases, the information indicates whether a same transmit beam is used to transmit a set of RS resources (e.g., symbol, sub-symbol, or frequency resources) or whether different transmit beams are used to transmit the set of 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.

Numerous other aspects are provided.

The UE may then receive one or more TRSs, and may perform channel measurement in accordance with the set of updated TRS parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A repeater extends coverage of wireless communications services between two wireless nodes (a base station and a user equipment (UE)). A network control node (e.g., a base station) receives a first indication of a capability of a repeater to detect a time division duplexing (TDD) pattern of a channel between the base station and the UE. The base station transmits, to the UE and via the repeater, one or more parameters associated with the UE performing one or more channel measurements and reference signals for the channel measurements. The base station transmits, to the repeater, a second indication of a TDD pattern of the channel based on the capability of the repeater. Based on the indication of the TDD pattern, the repeater adjusts one or more radio frequency components of the repeater.
