Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a timing advance value to use for an uplink transmission based on a unified transmission configuration indicator (TCI) state associated with the uplink transmission. In some examples, the control signaling configuring a unified TCI state for an uplink transmission may indicate the timing advance value for the uplink transmission. In some examples, the UE may receive control signaling indicating an association between a set of timing advance values for the component carrier associated with a set of unified TCI states or a set of unified TCI groups, and the UE may determine the timing advance value for a given uplink transmission based on the TCI state or TCI group indicated for the uplink transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may communicate with a second network node using a line-of-sight (LOS) multiple input multiple output (MIMO) configuration at a frequency. The first network node may communicate, based at least in part on a multi-user MIMO (MU MIMO) mode, with a third network node using the LOS MIMO configuration and at the frequency, wherein the MU MIMO mode corresponds to an antenna system configuration of the rectangular antenna array, wherein the antenna system configuration includes at least one of an antenna assignment scheme, an antenna amplitude configuration, or an antenna phase configuration.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may receive a configuration from a base station (BS). The configuration may indicate transmission parameters associated with different symbols such as sub-band full duplex (SBFD) symbols and non-SBFD symbols. For example, the transmission parameters may indicate power control parameters (e.g., a received power target value, a power control factor value, a closed-loop power control value) and a unified transmission configuration indicator (TCI) (e.g., a joint uplink and downlink TCI state, separate uplink and downlink TCI states). The UE may transmit uplink transmissions to the BS, in accordance with the transmission parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or relay node may transmit a beam report indicating a polarization layer mismatch (achievable rates are different for the first and second polarizations, or positioning estimation accuracy is different for the first and second polarizations). The report may include an indication of an imbalance in signal strength, an estimation error for the two polarizations, one or more beam pairs that are not supported across the two polarizations, a preferred polarization, or a combination thereof. In response to the beam report, the network entity may adjust one or more parameters, and may transmit accordingly. A relay node may indicate non-co-located polarization array construction via capability information. The UE may then transmit feedback indicating a direction of steered beams at the UE. The relay node performs relay operations based on transmission characteristics selected from the beam direction information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects involve enhancing an inter-user-equipment coordination (IUC) framework to enable user equipment (UE) to perform beam sweeping over the sidelink. Some aspects more specifically relate to fine-tuning beams, such as transmit beams or receive beams, using one or more IUC requests. In some aspects, multiple transmit beams or multiple receive beams may carry respective IUC requests and associated beam signals. In some aspects, one transmit beam or one receive beam may carry an IUC request and associated beam signal, multiple remaining transmit beams or receive beams may carry associated beam signals, and the transmit UE or the receive UE may identify a fine-tuned transmit beam or a fine-tuned receive beam responsive to, based on, or otherwise associated with the IUC request and associated beam signals.

Abstract: An integrated access and backhaul (IAB) node may establish a first connection with a first base station, establish a second connection with a second base station, and receive an indication, from the first base station or the second base station, that indicates at least one of the first base station or the second base station is to serve as an IAB donor for the IAB node. The first base station may indicate to the second base station, based on the second connection being established with the IAB node, that at least one of a first base station or the second base station is to serve as an IAB donor for the IAB node.

Abstract: A method of wireless communication by an integrated access and backhaul network (IAB) donor transmits a configuration message on a source path to a first IAB node via a first distributed unit of the IAB donor. The method also instructs the first IAB node to delay delivery of the configuration message to a second node. The method migrates at least part of communications to the first IAB node from the source path to a target path via a second distributed unit. Another method of wireless communication is executed by a first integrated access and backhaul network (IAB) node. The method receives a first configuration message over a source path to a first IAB donor via a first distributed unit of the first IAB donor. The method also delays delivery of the first configuration message to a second node until a trigger occurs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may detect and report blockage conditions based on measuring signal strengths of reference signals. A UE may determine a slew rate for the signal strength, corresponding to a rate of change of a signal strength parameter (e.g., a reference signal received power (RSRP) or a received signal strength indicator (RSSI)) with respect to time, and report the slew rate to a base station to indicate signal strength degradation (e.g., due to a blockage). In some examples, the UE may define multiple slew rates associated with different rates of change of the signal strength parameter with respect to time. When the UE crosses a level of slew rate, the UE may indicate this to the base station to initiate mitigation procedures. In some examples, the techniques described herein may be extended to reporting slew rates for multiple beams.
