Abstract: A design is provided for spatially multiplexing uplink channels. A user equipment (UE) detects that a Physical Uplink Control Channel (PUCCH) and a Sounding Reference Signal (SRS) are to be transmitted simultaneously. The UE decides to spatially multiplex the PUCCH and the SRS for simultaneous transmission via different sets of one or more antennas. The UE determines time and frequency resources for the PUCCH and the SRS to avoid collision of at least a portion of the PUCCH with the SRS. The UE transmits the spatially multiplexed PUCCH and SRS using the determined time and frequency resources.

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.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support aperiodic and cross component carrier PRSs. Generally, the described techniques provide for receiving a dynamic trigger indicating that a UE is to monitor for one or more downlink positioning reference signals (PRSs). The UE may generate a timing measurement for the one or more downlink PRSs, and may transmit a measurement report that indicates the timing measurement to a transmission/reception point. A UE may also transmit a capability indicator, indicating that the UE is capable of maintaining phase coherence for a PRS that spans multiple component carriers, receive control signaling that indicates multiple component carries on which the PRS is phase coherent, generate a timing measurement for the PRS based on the control signaling, and transmit a measurement report that indicates the timing measurement to the transmission/reception point.

Abstract: Certain aspects of the present disclosure provide techniques for avoiding transmission configuration indication (TCI) reselection (e.g., due to some bandwidth part (BWP) switching scenarios). An exemplary method generally includes configuring a UE with TCI state information for communication via multiple BWPs, wherein the TCI state information indicates quasi co-location (QCL) assumptions of at least first and second types and determining whether to reconfigure the TCI state of the UE to reflect a BWP switch, based on one or more rules that define BWP switching for reference signals (RSs) of at least one of the QCL assumption types without TCI state reconfiguration. Other aspects and embodiments are also claimed and described.

Abstract: Wireless communications systems and methods related to determining a QCL for receiving a reference signal are provided. A user equipment (UE) determines a QCL configuration for receiving a reference signal during a first time period based on a transmit beam direction to be used for transmission during the first time period. The user equipment receives the reference signal using a first receive beam direction based on the QCL configuration while transmitting a first communication signal using the transmit beam direction in a common frequency band during the first time period.

Abstract: Disclosed are techniques for receiving reference radio frequency (RF) signals for positioning estimation. In an aspect, a user equipment (UE) receives, from a network node, multiple resource sets for tracking (TRSs). Each TRS comprises a plurality of reference signal resources. The multiple TRSs are signals from a same antenna port or are quasi-co-located signals. The UE processes the multiple TRSs to determine positioning-related quantity(ies). The UE can estimate its position based on the positioning-related quantity(ies) and/or send the positioning-related quantity(ies) to the network.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may schedule a user equipment (UE) to transmit a sidelink data message to another UE. The base station may consider timing capabilities of the transmitting UE and the receiving UE when scheduling the sidelink communication. For example, the base station may schedule a feedback resource based on the timing capabilities of the transmitting UE and the receiving UE. The feedback resource may be scheduled with enough time such that the sidelink UEs can finish processing any sidelink communications in time to provide the feedback for the sidelink communications to the base station using the feedback resource.
