Abstract: A user equipment uses positioning reference signals (PRS) and non-PRS signals for position measurements. The non-PRS signals may be downlink and sidelink signals wherein the non-PRS are downlink or sidelink signals that are transmitted for purposes unrelated to positioning. Positioning assistance data is provided to the UE that associates the non-PRS signals with PRS-IDs. The association of the non-PRS signals to the PRS-IDs may be provided by a location server or serving base station. After performing positioning measurements using non-PRS signals, the UE reports measurement information using the PRS-IDs to identify the non-PRS signals used to generate the positioning measurements.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

Abstract: In a positioning session for a user equipment (UE), one or more base stations may receive and derive positioning measurements from uplink (UL) transmission from the UE that include a physical resource block (PRB) interlaced waveform based on at least one of interlaced physical uplink control channel (PUCCH) resource blocks, interlaced physical uplink shared channel (PUSCH) RBs resource blocks, interlaced sounding reference signal (SRS), interlaced uplink (UL) positioning reference signal (PRS), or a combination thereof. The interlaced waveforms span a greater wavelength than if interlacing were not used, and an enhanced accuracy requirement for the positioning measurements based on the span may be used for the positioning measurements. The UL interlaced PRBs may be used for UL positioning measurements for combined downlink (DL) and UL positioning measurements. The base station may report the positioning measurements along with the channel used and enhanced accuracy requirements to a location server for positioning.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) engaged in a positioning session with a transmission-reception point (TRP) receives, during a first state, a configuration of one or more sounding reference signal (SRS) resources, receives a first association between at least one SRS resource of the one or more SRS resources and at least one random access channel (RACH) resource of one or more RACH resources, switches out of the first state during an ongoing positioning session, and transmits, while outside the first state, at least a first signal of a RACH procedure to the TRP using transmission properties based on the first association between the at least one SRS resource and the at least one RACH resource.

Abstract: Techniques for compatibility between UEs that transmit SRS in only an existing SRS region and UEs that can transmit SRS using resources in an existing SRS region, an added SRS region, or both. Techniques for frequency domain subbband hopping using counters or subband hop shifts are disclosed. Techniques for compatibility for SRS transmissions that can use different scrambling sequence IDs, comb types, sequence/group hopping, and open loop power control are disclosed.

Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a device, such as a user equipment (UE), may receive, from one or more base stations during a first time unit, a control signal including an indication of a reference signal bundling configuration associated with one or more physical channel types which may be potentially scheduled during a set of time units after the first time unit. The UE may determine the set of time units based on the indication of the reference signal bundling configuration. Additionally or alternatively, the UE may receive scheduling configuration of one or more physical channels, and the one or more physical channels during one or more second time units of the set of time units. The UE may then bundle the one or more physical channels based on the reference signal bundling configuration.

Abstract: Methods and apparatus are disclosed according to certain aspects of the present disclosure. The methods and apparatus effect determination that a transmission configuration indicator (TCI) state is to be changed for a wireless transmission channel, where the channel includes time domain bundling of demodulation reference signals (DMRSs) across two or more symbols. Responsive to the determination that the TCI state is to be changed, the time domain bundling of the DMRSs in the transmission channel is selectively stopped prior to the TCI state change.

Abstract: Certain aspects of the present disclosure provide techniques for rate matching PDSCH around NZP CSI RS transmissions in multi-TRP scenarios. In some cases, a network entity may signal a rate matching behavior to a user equipment (UE) for processing a physical downlink shared channel (PDSCH) configured with a first quasi co-location association and transmitted from a first transmission reception point (TRP) that potentially collides with one or more types of non-zero power (NZP) reference signals (RS) configured with a second quasi co-location association and transmitted from a second TRP using one or more resource sets.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

Abstract: A method comprises: selecting, from a first number of first receive (RX) beams having a first beam width, a first RX beam to form a first beam-pair with a first transmit (TX) beam from one or more base stations, the selection being based on a first measurement of a first reference signal received by the UE using the first beam-pair; selecting, from a second number of second RX beams having a second beam width, a second RX beam to form a second beam-pair with the first TX beam, the selection being based on a second measurement of a second reference signal received by the UE using the second beam-pair, the second number of second RX beams being smaller than the first number of first RX beams, the second beam width being narrower than the first beam width; and performing a location estimate operation using either the second beam-pair, or a third beam-pair derived from the second beam-pair.
