Abstract: Disclosed are techniques for scheduling uplink (UL) and downlink (DL) physical layer resources for a serving node and a user equipment (UE) for round trip time (RTT) and observed time difference of arrival (OTDOA) based positioning. In an aspect, a serving node and/or a network entity configure the UL and DL physical layer resources, and inform the UE. A network node transmits RTT measurement (RTTM) signal to the UE and receives RTT response (RTTR) signals from the UE. The network node measures the times the RTTM signals are transmitted and the times the RTTR signals are received. The UE provides to serving node processing times indicating a duration between the UE receiving the RTTM signals and the UE transmitting the RTTR signals. The RTTs are calculated from the times measured by the network node and the processing times provided by the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit, to a second wireless device, capability control signaling indicating a first quantity of beam switches is supported within a first time period for a first antenna subarray, a first antenna module, or both, of the first wireless device. The first wireless device may receive, from the second wireless device in accordance with the capability control signaling, a grant scheduling one or more messages and indicating a set of beams of the first wireless device over which to communicate the one or more messages in respective transmission time intervals (TTIs) of the first time period. The first wireless device may then transmit or receive, over the first time period using the first antenna subarray, the first antenna module, or both, the one or more messages using the set of beams.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a positioning reference signal (PRS) configuration, the PRS configuration including at least a PRS periodicity defining repetitions of one or more PRS resources associated with at least a first transmission-reception point (TRP), receives a measurement gap configuration including at least a measurement gap repetition period (MGRP) defining repetitions of a measurement gap, and performs one or more positioning measurements of at least the one or more PRS resources during one or more repetitions of a measurement period, the one or more repetitions of the measurement period having an effective measurement periodicity, the effective measurement periodicity based on an alignment periodicity and a time period T during which the UE can process a duration N of PRS symbols, the alignment periodicity based on the PRS periodicity and the MGRP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sensing signal of a radio frequency (RF) sensing procedure at a first transmit power. The UE may receive, from a base station at least in part in response to the first sensing signal, a power control message for sensing signals of the RF sensing procedure. The power control message may indicate a power control strategy for transmitting sensing signals of the RF sensing procedure. The UE may then transmit, at a second transmit power based on the received power control message, a second sensing signal of the RF sensing procedure.

Abstract: Disclosed are techniques for reducing overhead of low layer positioning reports. In an aspect, a user equipment (UE) operating in discontinuous reception (DRX) mode determines that the UE is not expected to wake up during a next DRX ON duration of a DRX cycle; determines, based on one or more factors, whether to wake up during the next DRX ON duration to transmit a positioning measurement report or an uplink positioning reference signal (UL-PRS); and based on the determination: wakes up and transmits the positioning measurement report or the UL-PRS during the next DRX ON duration, or remains in a DRX sleep state and refrains from transmitting the positioning measurement report or the UL-PRS during the next DRX ON duration.

Abstract: Methods, systems, and devices for wireless communications are described that provide for mesh connectivity between integrated access and backhaul (IAB) nodes. A first node of an IAB network may determine a routing address for a second node, and communications may be transmitted to the second node based on the routing address to allow for coordination between the first and second nodes. The first node may detect a discovery signal of a second node, and may determine to communicate with the second node based on the discovery signal. The first node may obtain the routing address based on one or more of transmitting a request for the routing address to a third node, establishing a sidelink connection with the second node to obtain the routing address, receiving a mapping between routing addresses and cell IDs that are transmitted in discovery signals, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communication are described that support discontinuous scheduling. A base station may transmit, to a user equipment (UE), a grant of resources of a communication channel over a multiple of aggregated TTIs. The UE may monitor a control channel for the grant of resources transmitted by base station. The base station and the UE may identify a location of an excluded TTI within the plurality of aggregated TTIs. The excluded TTI may correspond to a TTI for communicating synchronization signals, random access channel (RACH) signals, or the like. The base station may communicate with the UE via the resources of the communication channel over at least a subset of the aggregated TTIs based on the grant and the location of the excluded TTI.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a random access occasion may overlap in time with a synchronization signal block resource, where the random access occasion and the synchronization signal block resource have a same index. In some such examples, a base station may transmit, to a user equipment (UE), an indicator of a mapping of the random access occasion to an uplink beam that is associated with a synchronization signal block resource with a different index than the random access occasion. The UE may transmit, to the base station, a random access preamble over the random access occasion using the uplink beam.
