  • Publication number: 20220053347
    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.

  • Publication number: 20220022107
    Abstract: When a user equipment (UE) is configured with a primary cell (PCell) and one or more secondary cells (SCell), scheduling of uplink (UL) and/or downlink (DL) resources for the UE may be received from the primary cell. However, in some circumstances, the primary cell may be unable to provide such scheduling related information. In such circumstances, one or more secondary cells may be enabled to provide scheduling related information to the UE such that cells other than the primary cell may function as scheduling cells. Information regarding dormancy states of the cells (primary and/or secondary) may also be provided by the scheduling cells.

  • Publication number: 20220015057
    Abstract: A target user equipment (UE) identifies other UEs that are available for a positioning reference signal (PRS) exchange for sidelink assisted positioning of the target UE. The target UE may provide to a network entity, such as a location server, the identifications of the UEs that are available for the sidelink-assisted positioning of the target UE. The network, entity may generate and provide for sidelink-assisted positioning the PRS configurations for UEs, which may include the one or more UEs recommended by the target UE. The target UE may provide a list of UEs, in response to a request from the network entity, in response to receipt of a network generated list provided to the target UE, or in response to a determination that PRS measurements based on previously acquired UE PRS configurations are inadequate. The sidelink-assisted positioning may be used when the target UE is present in a null-zone.

  • Publication number: 20210377698
    Abstract: Methods, systems, computer-readable media, and apparatuses are described for reporting, in support of positioning a UE, information about consistencies of positioning reference signal (PRS) measurements, PRS resources, PRS resource sets, or transmission and reception points (TRPs). In some embodiments, a UE receives PRS resources from TRPs and performs PRS measurements based on the PRS resources. The UE determines whether certain PRS measurements, PRS resources, PRS resource sets, or TRPs contribute to a consistent position estimate and/or consistent positioning measurements. The UE reports to a device, such as to a location server, information about consistent groups, where each consistent group identifies a set of such consistent elements.
