Abstract: Various aspects of the disclosure relate to power control for independent links. For example, power control at a device may be based on transmissions on multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, power control for the first device may be based on power control commands received on multiple links. In some scenarios, a power control constraint may be met taking into account the transmission power on multiple links.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may transmit signaling indicating antenna module capability information including geometric shape information corresponding to one or more antenna modules of the UE. The geometric shape information is based on an availability of multiple boresight directions of the one or more antenna modules. The UE may receive an indication of a number of reference signals (RSs). The number of RSs is based on the antenna module capability information.

Abstract: Methods, systems, and devices for wireless communications are described. Repetitions of a reference signal may be transmitted by a first device. In some examples, the repetitions may be quasi-colocated with one another, share an antenna port, or both. The repetitions of the reference signal may arrive at a reconfigurable surface. The reconfigurable surface may apply a modulation sequence to the repetitions of the reference signal and output modulated repetitions of the reference signal in a direction based on a reflective state of the reconfigurable surface. A signal including the modulated repetitions of the reference signal may be received by a second device and combined with the modulation sequence used by the reconfigurable surface to obtain a combined signal. The combined signal may be used to determine, for the reconfigurable surface, information about a channel between the first device and the second device.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may perform an adjustment procedure for one or more frequency resources of an uplink message or a downlink message to avoid collisions within a sub-band full duplex (SBFD) slot. In some cases, the UE may identify that a resource allocation for the downlink message extends over at least a portion of a resource allocation for the uplink message (or a guard band for the uplink message), and may perform the adjustment procedure for the uplink resource allocation. The adjustment procedure may include only using resources of the uplink resource allocation that do not overlap resources of the downlink resource allocation, shifting the uplink resource allocation within an uplink sub-band, or both. Additionally, or alternatively, such techniques may be extended to adjust the downlink resource allocation, for example, based on a type of the downlink message.

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 user equipment (UE) may communicate, within a time period, with a network node via a primary communication path comprising a link between the network node and a first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE. The UE may communicate, within the time period, with the network node via at least one secondary communication path comprising a link between the UE and a second electromagnetic radiation reflection relay network node. Numerous other aspects are described.

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. Numerous other aspects are described.

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.
