Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a first network entity. The techniques may generally involve generating a message with entries that represent blocks of physical resource blocks (PRBs), for transmitting reference signals over a fronthaul interface using modulation compression; transmitting the message to a second network entity via the fronthaul interface; and processing reference signals, transmitted in the blocks of PRBs on the fronthaul interface using modulation compression.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may provide, to a second network node, an indication of a configuration of a beam group type that supports indications of activity statuses of beams for a frequency resource range. The first network node may provide, to the second network node, an indication of the activity statuses of the beams for the frequency resource range, the indication of the activity statuses of the beams including an indication of a first set of beams that are active and an indication of a second set of beams that are inactive. Numerous other aspects are described.

Abstract: A method, apparatus, and computer-readable medium for wireless communication at a first UE, such as C-V2X. The apparatus receives a message comprising a control channel and a data channel from a second UE. The apparatus decodes, at the physical layer, a subset of fields of the control channel. The apparatus determines a priority of the message relative to the first UE based on the subset of fields and determines, at the physical layer, whether to decode the message based on the priority of the message relative to the first UE. The apparatus forwards the message to higher OSI layers for a next stage of decoding when a determination is made at the physical layer to decode the message. The apparatus skips the next stage of decoding of the message at the higher OSI layers when the determination is made at the physical layer not to decode the message.

Abstract: In order to enable asynchronous, autonomous reception beam switching at a UE while minimizing degradation due to a transient in link performance, a method, apparatus, and computer-readable medium for wireless communication are provided. The apparatus receives CSI-RS on different reception beams in different symbols, wherein one reception beam being a current serving reception beam, and determines whether to switch to a different reception beam based on a SPEFF metric for the different reception beam and/or a severity of a potential link transient qualified in terms of the expected CQI/MCS degradation in the channel. The apparatus may switch from a current serving reception beam to a second reception beam when a first channel quality for the current serving reception beam is within a threshold value of a second channel quality for the second reception beam, the second channel quality being measured using a current configuration.

Abstract: Certain aspects of the present disclosure provide techniques for physical resource block allocation alignment. An example method, performed at a first network entity, includes transmitting beamforming weights (BFWs) to a second network entity, each beamforming weight to be applied to a different bundle of one or more physical resource blocks (PRBs), transmitting, to the second network entity, one or more parameters indicative of a misalignment between an allocation of PRBs and at least one logical structure, and processing signals transmitted between the first and second network entities, with beamforming applied to PRB bundles using the BFWs, in accordance with the one or more parameters.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications network may operate in accordance with an open-RAN (ORAN) network specification which may support functional splitting between the ORAN distributed unit (O-DU) and the ORAN radio unit (RU). The O-DU may communicate with the O-RU using control messaging. The control message may include a resource resource element (RE) mask and a resource symbol mask, the resource RE mask indicating frequency resources to be allocated for a reference signal transmission across a set of antenna ports and the resource symbol mask indicating time resources to be allocated for the reference signal transmission. Additionally or alternatively, the O-DU may transmit a control message including a puncturing resource RE mask indicating frequency resources for applying a puncturing pattern and a symbol mask indicating time resources for applying the puncturing pattern during a transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication identifying whether a physical resource block (PRB) allocation boundary discontinuity is present. The UE may communicate using a precoding configuration applied based at least in part on the indication identifying whether the PRB allocation boundary discontinuity is present. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, within a subframe, a plurality of sidelink control channel signals providing scheduling information for a plurality of sidelink shared channel signals that are also received within the subframe. The UE may determine to use one or more of the plurality of sidelink control channel signals as pilot signals for decoding the plurality of sidelink shared channel signals. The UE may decode the plurality of sidelink shared channel signals based at least in part on the plurality of sidelink control channel signals as pilot signals.
