Abstract: Techniques are provide for calibrating device timelines for use in passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first device at a first time, receiving a second positioning reference signal from a second device at a second time, receiving a timeline difference value associated with the first device and the second device, and determining a time difference of arrival between the first positioning reference signal and the second positioning reference signal based at least in part on the timeline difference value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may perform a first encoding operation on source packets that generates a first set of network coding encoded packets and may broadcast the first set of network coding encoded packets for reception by a plurality of receivers. The transmitter may receive feedback information associated with the first set of network coding encoded packets, the feedback information indicating that a first subset of network coding encoded packets were received by at least one of the plurality of receivers, the feedback information further indicating that one or more receivers of the plurality of receivers did not successfully recover all of the plurality of source packets. The transmitter may broadcast a second set of network coding encoded packets that does not include any of the first subset of network coding encoded packets. Numerous other aspects are provided.

Abstract: Techniques are provide for passive positioning of user equipment (UE) with analog beamforming. An example method for positioning a user equipment includes receiving a first positioning reference signal from a first base station at a first time, receiving a first timing difference value based on two or more positioning reference signals transmitted from the first base station, receiving a second positioning reference signal from a second base station at a second time, receiving a second timing difference value based on two or more positioning reference signals transmitted from the second base station, and determining a time difference of arrival between the first positioning reference signal and the second positioning reference signal based at least in part on the first timing difference value and the second timing difference value.

Abstract: Techniques and apparatus for avoiding hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One technique involves receiving an indication of SPS configurations, where each SPS configuration allocates a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. A conflict is detected between a first HARQ process ID associated with a first SPS occasion of a first SPS configuration and a second HARQ process ID associated with a second SPS occasion of a second SPS configuration, where the first SPS occasion occurs prior to the second SPS occasion. At least one action to resolve the conflict is taken based on predetermined rule(s), in response to detecting the conflict.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling chain design. Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method generally includes determining a limit associated with a quantity of a plurality of downlink control information (DCI) for each of at least one scheduling chain, each of at least one of the plurality of DCI to be transmitted on one of a plurality of data channels, and wherein each of the plurality of DCI in the scheduling chain schedules another one of the plurality of data channels; and transmitting the plurality of DCI on the plurality of data channels in accordance with the determination to a user-equipment (UE).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a signal measurement. The UE may select, based at least in part on a result of performing the signal measurement, a channel state information (CSI) report parameter, from a plurality of CSI report parameters. The plurality of CSI report parameters may be included in a CSI reporting configuration configured for the UE. The UE may transmit an indication of the selected CSI report parameter in uplink control information (UCI). Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). An example method by a user equipment (UE) generally includes receiving a first physical downlink control channel (PDCCH) in a control channel monitoring occasion, the first PDCCH indicating at least one dynamic CORESET; and receiving a second PDCCH within the dynamic CORESET, wherein the second PDCCH is received in accordance with at least one QCL assumption for the at least one dynamic CORESET.
