Abstract: In an aspect, a UE estimates channel state(s) of channels(s) between the UE and network node(s) based on DL RS(s) for positioning that are scheduled and transmitted on DL resources from network node(s). The UE may apply TR filter(s) derived based on the estimated channel state(s) to a UL-RS for positioning. The UE may transmit the TR filtered UL-RS on UL resources which are associated with the DL resources of the DL-RS(s) and which are scheduled by the network node(s). The association between the UL resources and the DL resources may be indicated to the UE by the network node(s).

Abstract: This disclosure provides systems, methods and apparatuses for switching configurations for uplink transmission switching. A user equipment (UE) may receive, from a network entity such as a base station, a switching configuration for an uplink transmission switching for three or more carriers. The switching configuration may be associated with switching one or more uplink transmission chains of the UE from or to one or more carriers of the three or more carriers within a time period. The switching configuration may be associated with a UE capability. The switching configuration may permit switching from or to one carrier within the time period associated with the UE capability. The switching configuration may permit switching from or to two carriers within the time period associated with the UE capability. The switching configuration may depend on the UE capability, thereby not causing the uplink transmission switching to degrade a performance of the UE.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PUCCH/PUSCH DMRS bundling. A UE may transmit, to a network entity, a first indication of a maximum DMRS bundling duration for maintaining transmit phase coherence for transmitted DMRS. The UE may receive, from the network entity based on the first indication of the maximum DMRS bundling duration, a second indication of at least one of a DMRS bundling activation or a DMRS bundling duration. Based on the at least one of the DMRS bundling activation or the DMRS bundling duration, the UE may transmit at least one UL repetition including bundled DMRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a nominal time domain window duration and at least one of a quantity of nominal time domain windows or a quantity of actual time domain windows for demodulation reference signal bundling. The UE may calculate, in accordance with the quantity of nominal time domain windows being a single nominal time domain window or the quantity of actual time domain windows being a single actual time domain window, and in accordance with an indication that antenna switching is enabled, an adjusted nominal time domain window duration in accordance with applying a parameter to the nominal time domain window duration. The UE may calculate an adjusted quantity of nominal time domain windows and may identify a plurality of actual time domain windows. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may update its channel state information (CSI) on a sidelink between a first user equipment (UE) and one or more second UEs aperiodically using control information to trigger the CSI reporting process. The aperiodic CSI process may include the base station transmitting a timing requirement and control information to a UE. The control information contains a CSI request may be received and decoded at the UE. According to the CSI request, the first UE may transmit a reference signal on the sidelink for the second UE(s) to measure. The UE(s) may generate and transmit a CSI report on the sidelink to first UE, and the first UE may aggregate the received CSI report(s) and transmit them to the base station within the time period specified by the timing requirement received in the control information.
