Abstract: Apparatus, methods, and computer-readable media for facilitating cross-carrier beam association are disclosed herein. An example method for wireless communication at a UE includes receiving, from a base station, an indication of a cross-carrier beam association associated with a first carrier and a second carrier different than the first carrier. The example method also includes determining an association between a first set of beams of the first carrier and a second set of beams of the second carrier based on the indication of the cross-carrier beam association. Additionally, the example method includes receiving on the first set of beams and the second set of beams based on the determined cross-carrier beam association.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example, the BS and UE each determine at least one timing value associated with an effective receive time for the PDCCH based upon a reference symbol of the PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message indicating that a control resource set for a downlink control channel is associated with a plurality of demodulation reference signal (DMRS) ports. The UE may determine, based at least in part on the configuration message, that a first set of DMRS resource elements in a first symbol of the control resource set correspond to a first DMRS port of the plurality of DMRS ports and a second set of DMRS resource elements in a second symbol of the control resource set correspond to a second DMRS port of the plurality of DMRS ports. The UE may decode the downlink control channel based at least in part on the determining.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a user equipment (UE) measures at least a line-of-sight (LOS) path and a non-line-of-sight (NLOS) path of a first downlink positioning reference signal (DL-PRS) from a first transmission-reception point (TRP), measures at least an LOS path and an NLOS path of a second DL-PRS from a second TRP, measures at least an LOS path and an NLOS path of a third DL-PRS from a third TRP, and enables a location of a non-participating target object to be determined based, at least in part, on reference signal time difference (RSTD) measurements between a time of arrival (ToA) of the LOS path of the first DL-PRS and the ToAs of the NLOS paths of the first, second, and third DL-PRS. In an aspect, the non-participating target object does not participate in determining its own location.

Abstract: Wireless communication devices, systems, and methods related to mechanisms for transmitting and receiving reference signals in a high-speed train (HST) single frequency network (SFN). A base station (BS) determines a first frequency pre-compensation value for a reference signal transmitted via a first transmission and reception point (TRP) and a second frequency pre-compensation value for a reference signal via a second TRP. The BS notifies a user equipment (UE) of the first and second pre-compensation values through at least one of the TRPs. The BS applies the first pre-compensation value to the reference signal via the first TRP and the second pre-compensation value to the reference signal via the second TRP. The UE adjusts its tracking loop for the reference signal based on the pre-compensation values, reducing estimation and/or search overhead at the UE.
