  • Publication number: 20240129781
    Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) identifies a set of positioning sources, each positioning source comprising a positioning reference signal (PRS) resource, a PRS resource set, a PRS frequency layer, and/or a transmission/reception point (TRP). From the set of positioning sources, the UE identifies a consistency group comprising a collection of positioning sources grouped based on expected values of at least one metric of a reference signal from each positioning source, measured values of the at least one metric for the reference signal from each positioning source, and an error threshold. The UE identifies one or more subsets of positioning sources within the consistency group, each subset having at least one metric error value. The UE reports, to a network entity, information about the consistency group and information about at least one of the subsets of positioning sources within the consistency group.

  • Patent number: 11963023
    Abstract: Methods, systems, and devices for wireless communications are described. Some systems may support the transmission of a predicted negative acknowledgment (NACK) indication for a downlink data message. In some cases, a base station may transmit a downlink data message to a user equipment (UE). The UE may perform a decoding process for the message. The UE may determine whether the decoding process is likely to fail during a first portion of the decoding process prior to completion of the decoding process. The UE may transmit a predicted NACK message to the base station prior to a feedback opportunity configured for the UE to transmit feedback based on a result of the completed decoding process. The base station may determine whether to retransmit the downlink data message based on the predicted NACK message, such that the predicted NACK message may reduce the latency associated with retransmission of downlink data messages.
