    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting sounding reference signal (SRS) resources with frequency hopping. In some implementations, a user equipment (UE) may use different SRS ports, different antenna ports, different numbers and sizes of SRS resources, different periodicities, different offsets, different transmission comb values, different number of symbols, different power control parameters, and/or different transmission comb offset values for SRS transmissions on different frequency subbands of the frequency hopping pattern to ensure that sounding operations cover all antennas of the UE, cover the entire frequency range of interest, and provide sufficiently dense SRS transmissions from which a base station can determine the best channel for DL transmissions while also using a minimum amount of SRS resources and consuming minimal power in the UE.

    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to identify a first set of scheduled transmissions to be received using a first set of time-frequency resources, where reference signals of the first set of transmissions may be bundled according to a first reference signal bundling pattern. The UE may identify a second scheduled transmission to be received using a second set of time-frequency resources that overlaps with the first set of resources. The UE may determine a second reference signal bundling pattern for bundling the reference signals received in the first set of transmissions. For example, the UE may modify the first reference signal bundling pattern to determine the second reference signal bundling pattern. The UE may receive the second scheduled transmission and the first set of scheduled transmissions according to the second reference signal bundling pattern.

    Abstract: Techniques for positioning a NR bandwidth-limited user equipment (UE) are provided. An example method of positioning performed by a bandwidth-limited UE includes transmitting a first timing measurement signal to at least one proximate premium UE, wherein the at least one proximate premium UE is capable of using more bandwidth than the bandwidth-limited UE, receiving a second timing measurement signal from the at least one proximate premium UE, and determining location information for the bandwidth-limited UE based at least on the first timing measurement signal and the second timing measurement signal.

    Abstract: A user equipment (UE) includes: a transceiver configured to receive positioning signals; a memory; and a processor, communicatively coupled to the transceiver and the memory, configured to: send, via the transceiver to a network entity, a capability indication that includes a first positioning-method indication indicating that the processor supports simultaneous processing of a first combination of positioning methods; and simultaneously process one or more first positioning signals in accordance with the first combination of positioning methods to determine first position information for the UE.

    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a UE may receive an indication of a set of sounding reference signal (SRS) parameters corresponding to a set of SRS resources for transmitting SRSs, where the set of SRS resources may refer to frequency, or time, or both. In some examples, the SRS parameters may include, among other examples, a frequency allocation, a frequency overlap parameter, a number of allocated symbols, a comb value, a cyclic shift, a comb offset, a frequency hopping parameter, a repetition parameter, a symbol grouping parameter, or any combination thereof. The UE may determine an SRS configuration for the one or more SRSs based on the set of SRS parameters and transmit the one or more SRSs based on the configuration. In some examples, the SRS configuration includes a configuration for SRS frequency hopping, or SRS repetition, or both.

    Abstract: Wireless communications systems and methods related to energy harvesting services are provided. A first wireless communication device transmitting, to a second wireless communication device, at least one of an energy request or an energy level indication. The first wireless communication device receives, from the second wireless communication device in response to the at least one of the energy request or the energy level indication, an indication of one or more resources for receiving a radio frequency (RF) energy harvesting signal. The first wireless communication device receives, from the second wireless communication device in the one or more resources, the RF energy harvesting signal. The first wireless communication device converts the RF energy harvesting signal to energy.

    Abstract: Wireless positioning accuracy of a user equipment (UE) is impacted by locations of the transmit/receive points (TRPs) and UE for wireless positioning. To improve the accuracy of estimated locations, a geometric dilution of precision (GDOP) may be determined for different groups of candidate TRPs, with the GDOP indicating a potential positioning error associated with the group of candidate TRPs. A UE may determine GDOPs for different combinations of candidate TRPs. One or more devices of a wireless network (e.g., a location server and/or a UE for positioning) may select or exclude one or more candidate TRPs from being used for wireless positioning of a UE based on the determined GDOPs. Exclusion or selection of candidate TRPs for wireless positioning may also be based on quality measurements of PRSs (such as an RSRP or SNR) or a time duration associated with measuring the PRSs from the candidate TRPs to be selected.
