Abstract: Techniques described herein provide for a mobile device communicating a timing quality metric related to an uplink (UL) signal for UL and/or downlink-uplink (DL-UL) positioning techniques. The timing quality metric can be indicative of an accuracy of the transmission timing of one or more reference signals (e.g., in relation to a downlink (DL) signal or other UL reference signal) and may be communicated using an indexed and/or enumerated value. This information can be included as an information element (IE) in a report provided by the mobile device to a receiving network entity or location server.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, downlink control information (DCI) that triggers one or more aperiodic sounding reference signal (SRS) resource sets. The UE may determine that a candidate slot is an available slot associated with the one or more aperiodic SRS resource sets based at least in part on available information at a timestamp of the candidate slot, and one or more of a radio resource control (RRC) configuration or dynamic event information. The UE may transmit, to the base station, an aperiodic SRS using the one or more aperiodic SRS resource sets of the available slot. Numerous other aspects are described.

Abstract: Aspects relate to delaying transmission of a sounding reference signal (SRS). A user equipment (UE) may transmit an SRS a certain number of slots after downlink control information (DCI) that triggers the transmission of the SRS. A base station may configure the UE with a set of delay parameters that are mapped to different bit values. The DCI that triggers the transmission of an SRS may include a bit field for indicating one of the delay parameters. A base station may set a bit in the bit field of the DCI to indicate that the UE is to use the corresponding delay parameter for the transmission of the SRS. A UE that receives the DCI may map the value of the DCI bit field to the set of delay parameters to determine the delay parameter to use for the SRS transmission.

Abstract: Techniques and apparatus for determining a transport block (TB) configuration and hybrid automatic repeat request (HARQ) acknowledgment (ACK)/negative acknowledgment (NACK) configuration for full duplex (FD) UE(s) are described. One technique involves receiving channel state information (CSI) report(s) from a UE operating in FD mode. At least one of a TB configuration or feedback type for a communication slot is determined based on the CSI report(s). The communication slot can include half duplex (HD) symbol(s) and FD symbol(s). An indication of at least one of the TB configuration or the feedback type is signaled to the UE. Another technique involves receiving, from a base station (BS), downlink data transmission(s) across a slot(s). A type of duplexing mode associated with each of the slot(s) is determined. The downlink data transmission(s) are acknowledged, based at least in part on the type of duplexing mode associated with each of the slot(s).

Abstract: Certain aspects of the present disclosure provide techniques for slot aggregation in new radio (NR) systems. A method of wireless communication by a user equipment (UE) includes receiving radio resource control (RRC) signaling providing a semi-static configuration for transmission and/or reception of a repeated transport block (TB) and/or a different TB in each of a plurality of aggregated slots. The UE transmits or receives the TBs in the plurality of aggregated slots based on the semi-static configuration. Another method is provided in which the UE transmits and/or receives a demodulation reference signal (DMRS) in each of a plurality of aggregated slots, each DMRS associated with a repeated TB or a different TB in the slot. The UE determines, based on received signaling, whether the DMRS use a same precoder or a different precoder and modulates and/or demodulates the TBs in the plurality of aggregated slots based on the determination.
