  • Publication number: 20250088330
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a sounding reference signal (SRS) in multiple slots. A network entity may determine precoding weights in three domains based on the SRS and output reference signals that are precoded based on the precoding weights. The network entity may output control signaling that indicates reference signal resource grouping information that the UE is to use for channel estimations. The reference signal resource grouping information may specify whether the ports in one group are precoded with identical or different spatial, frequency, and time domain weights. A UE may receive the precoded reference signals and the grouping information and report estimated channel metrics and an indication of selected ports per group to the network entity. The network entity may determine precoding in three domains for subsequent downlink communications.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message from a base station that schedules multiple transport blocks (TBs) to be transmitted to the UE. Accordingly, the UE may determine a bundling configuration for grouping the multiple TBs into separate groups of TBs such that separate acknowledgment (ACK) feedback messages are transmitted by the UE for each group of TBs to indicate whether each of the TBs in each TB group was correctly received and decoded. In some cases, the UE may determine the bundling configuration based on radio resource control signaling from the base station, DCI signaling from the base station, relationships or equations or tables defined for the UE, or a combination thereof. Additionally, the UE may determine resource locations and timelines for transmitting the separate ACK feedback messages.

  • Publication number: 20250063599
    Abstract: Methods, systems, and devices for wireless communications are described. A network entity (e.g., a base station or reader) may transmit an initial access trigger message (e.g., modulating a continuous wave transmission using amplitude shift keying (ASK)), and the trigger message may include an indication of a type of passive user equipment (PUE) or a PUE use case (e.g., high priority/latency-critical PUEs or low priority/latency non-critical PUEs). A receiving PUE may harvest energy from the initial access trigger message for transmitting an initial access response message including an identifier for the receiving PUE. The receiving PUE may transmit the initial access response message (e.g., on one or more initial access resources) using the harvested energy if the trigger message indicates the PUE's type of PUE or PUE use case. In some examples, the receiving PUE may ignore triggers for different types of PUEs or PUE use cases.
