  • Publication number: 20230262471
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a broadcast message via a cell associated with a network entity. The broadcast message may include an indication that the cell supports a first radio access technology (RAT) and a second RAT. In some examples, the first RAT may be associated with a first subcarrier spacing (SCS) and the second RAT may be associated with a second SCS. The UE may perform measurements of one or more reference signals associated with the first RAT based on the indication. In some examples, the one or more reference signals may be multiplexed with physical downlink shared channel (PDSCH) data. The UE may transmit a channel feedback report to the network entity based on performing measurements of the one or more reference signals, and may demodulate the PDSCH data using the first SCS and the second SCS.

  • Publication number: 20230247558
    Abstract: This disclosure provides methods, devices and systems for channel sounding for wireless communications. Some implementations more specifically relate to scheduling sounding reference signal (SRS) resource sets for wireless devices having more than 4 receive (RX) antenna ports. In some implementations, a base station may determine an antenna switching capability of a user equipment (UE). The antenna switching capability indicates a number of RX antenna ports of the UE. The base station schedules a number of SRS resource sets for the UE based at least in part on the number of RX antenna ports in excess of four. For example, the number of RX antenna ports may be equal to 8. As another example, the number of RX antenna ports may be equal to 6. The base station further receives, from the UE, uplink transmissions of one or more SRS resources for each of the scheduled SRS resource sets.

  • Patent number: 11683661
    Abstract: In an embodiment, a first node (e.g., a UE or a BS) performs a channel response measurement on a reference signal for positioning (e.g., UL reference signal such as SRS for positioning, or a DL PRS). The first node determines, for each of a plurality of peaks detected within the channel response measurement, peak-specific information comprising at least peak magnitude data that is based on a peak magnitude relative to a reference value. The first node reports the peak-specific information for the plurality of peaks to a second node (e.g., a BS, UE, or LMF). The second node receives the peak-specific information, and determines a positioning estimate for a UE based on the peak-specific information.

  • Publication number: 20230179295
    Abstract: Aspects presented herein may improve the precision and performance of a TDOA-based UE positioning scheme that is associated with an NTN. In one aspect, a UE receives, from a first satellite, a first PRS at a first reception time. The UE receives, from a second satellite, a second PRS at a second reception time and an indication of a transmission-reception time difference, the transmission-reception time difference being a difference between a time the second satellite transmits the second PRS to the UE and a time the second satellite receives an RS from the first satellite. The UE calculates an RSTD for the first PRS and the second PRS based at least in part on the first reception time of the first PRS, the second reception time of the second PRS, and the transmission-reception time difference.
