Abstract: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.

Abstract: A network management function of a relay network may identify relay node support of multi-mobile terminal (MT) operation, and may coordinate configuration of multiple backhaul links supported by the relay node via the multi-MT functionality of the relay node. In some cases, a relay node may transmit MT capabilities to the management function over a first established backhaul link, and the management function may configure a second backhaul link using a second MT function of the relay node. In other cases, the relay node may autonomously establish multi-MT connectivity based on preconfigured parent-selection policies, and the network management function may identify the relay node is dual-connected to the network management function. In either case, the network management function may configure backhaul routes (e.g., backhaul links) and resource configuration across the redundant topology.

Abstract: Methods, systems, and apparatuses are described for wireless communication at a base station. The base station may transmit a control message to a set of user equipments (UEs) using a directional transmission having a first beamform width. The base station may exchange, according to the control message, data messages with a first UE of the set of UEs using a directional transmission having a second beamform width. The second beamform width may be different from the first beamform width. The base station may exchange, according to the control message, data messages with a second UE of the set of UEs using a directional transmission having a third beamform width. The third beamform width may be different from the first beamform width, the second beamform width, or both.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a number of beam directions that satisfy a transmission power condition. The UE may select a beam direction for a random access signal by choosing one of the beam directions that satisfies additional criteria, such as transmitting a random access message at the next opportunity. The transmission power may be selected based on a target receive power and a path loss for the selected beam. In some cases, if the sum of the path loss for a beam direction and the target receive power exceeds a maximum transmission power by more than a predetermined amount, the random access signal will not be transmitted using that beam. In some cases, if a response to the random access is not received, a different beam direction may be selected, the transmission power may be increased, or both.

Abstract: Methods, systems, and devices for wireless communications are described that provide for hop-count indication in an integrated access and backhaul (IAB) network. An IAB-node may adopt and indicate multiple values for hop-count. The hop-count may be conveyed by a number of different reference signals and channels. A resource pattern and/or a slot pattern may also be associated with the hop-count to simply signaling. By associating the patterns with the hop-count, an IAB-node may be able to infer the resource pattern used by another IAB-node.

Abstract: Methods, apparatuses, and computer-readable mediums associated with a user equipment (UE) and a base station are provided for herein. In aspects, a UE may receive, from a base station, a beam modification command indicating at least one beam index for communicating through at least one beam on at least one channel. In an aspect, each beam index of the at least one beam index may indicate at least a direction for communicating through a corresponding beam of the at least one beam. The UE may communicate, with the base station, through the at least one beam corresponding to the at least one beam index on the at least one channel.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for generating and communicating reference signals. Certain aspects provide a method for communicating reference signals. The method includes selecting a demodulation reference sequence (DMRS) of a plurality of DMRSs for transmission in a synchronization signal block (SSB) based on a half-frame in which the SSB is transmitted. The method further includes transmitting the selected DMRS in the SSB.

Abstract: A first RAN may determine beamforming information for a UE served by the first RAN. Then, the first RAN may transmit, to a second RAN or a core network, paging information for the UE served by the first RAN, wherein the paging information comprises the beamforming information for the UE. A core network component, e.g., an AMF, may receive the paging information comprising the beamforming information for the UE and may send a paging request to a second RAN for the transmission of a paging message to the UE, wherein the paging request is based on the received paging information. The second RAN may receive, from the first RAN or from the core network, paging information for the UE comprising beamforming assistance information for the UE. The second RAN may then transmit a paging message to the UE based on the beamforming assistance information.

Abstract: Various aspects of the disclosure provide for methods of communication. One method, at a base station, involves determining a maximum number of consecutive MSG1 retransmissions that a user equipment (UE) is permitted to perform, and transmitting the maximum number of consecutive MSG1 retransmissions to the UE. Another method involves receiving a maximum number of consecutive MSG1 retransmissions to be performed, and transmitting consecutive MSG1 retransmission signals for the maximum number of times.

Abstract: Methods, systems, and devices for wireless communications are described that provide for multiple different receive beams at a user equipment (UE) that may be spatially associated with a single transmission beam from a base station. A UE may measure, using multiple different receive beams, multiple instances of a same reference signal transmitted by the base station using a same transmission beam. The UE may provide measurement reports associated with each of the measurements to the base station. A particular receive beam to be used for a downlink transmission may be selected from the multiple receive beams and may be indicated to the UE.
