Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate a connection release message via a first beam to release a connection between the UE and a network entity. The UE may obtain an indication associated with a second beam of a non-terrestrial network entity indicating a set of one or more beams associated with a paging early indication. The UE may monitor for the PEI paging message based on whether the first beam is included in the set of one or more beams. Alternatively, the UE may skip monitoring for the PEI based on the first beam being excluded from the set of one or more beams, and the UE may monitor for a paging message during a paging occasion. In some examples, the UE may receive a message indicating the set of one or more beams from the non-terrestrial network entity.

Abstract: Techniques are provided for calibrating group delay for a low-tier UE by leveraging the relatively high accuracy of RTT positioning for a premium UE. This can enable online/in-field group delay calibration of low-tier UEs, allowing for low-tier UEs to be calibrated when needed. Depending on desired functionality, techniques for calibration may include the use of RTT measurements with a base station, or an RTT measurement between the low-tier UE and the premium UE.

Abstract: Radio frequency (RF) sensing of a target object by a wireless network is supported by a sensing node and a network node using sensing assistance data. The sensing assistance data may include information for Doppler estimation from received RF signals. The information for Doppler estimation, for example, may include an indication of phase coherency of RF signals, such as phase coherence found in positioning reference signal (PRS) resources, resource sets, transmission reception points (TRPs), frequency layer or any combination thereof. The sensing assistance data may include an association of PRS resources and reference point objects (RPOs) so RF signals reflected from the RPOs may be excluded from the sensing measurements. The sensing assistance data may include beam pattern information for PRS resources for beam coordination for RF sensing.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a time period during which the UE is configured to receive grants scheduling communications for the UE, wherein the grants are associated with a first grant format type. The UE may determine that the grants include a feedback process identifier exceeding a threshold value. The UE may maintain a power saving state of a discontinuous reception procedure for a feedback process associated with the feedback process identifier during the time period based at least in part on the feedback process identifier exceeding the threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a waveform threshold for selecting a waveform type for transmitting a message of a random access procedure. The UE may select the waveform type for the message of the random access procedure based on the waveform threshold and a value associated with a power of signals received at the UE. The UE may transmit the message of the random access procedure to a network entity according to the waveform type selected for the message.

Abstract: Methods, systems, and devices for reducing latency for closed loop sidelink communications for non-terrestrial networks (NTNs) are described. In some examples, a first user equipment (UE) may transmit, to a network entity, a message requesting an allocation of sidelink resources for the first UE and an allocation of sidelink resources for a second UE. The first UE may receive, from the network entity in response to the request message, an indication of a first set of sidelink resources for the first UE. In some examples, the first UE may transmit one or more data messages to the second UE, including an indication of a second set of sidelink resources, an indication that the network entity may directly allocate the second set of sidelink resources, or both. In some example, the first UE may receive one or more data messages from the second UE on the second set of sidelink resources.

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.
