Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may communicate with multiple beacon devices (e.g., road side beacons), where messages from the road side beacons may be transmitted over a sidelink communications link and may be used to determine a speed and/or location of the wireless device. In some examples, the messages may carry public safety information, location information, navigation information, or other types of information, which may be used, for example, to notify the wireless device of a nearby event, to enable navigation, or the like. When receiving messages from the road side beacons, the wireless device may report a status to a base station, which may determine a relationship between transmissions from the wireless device and predict future transmissions based on the relationship. As a result, the base station may modify communications parameters in accordance with the status of the wireless device.

Abstract: Disclosed are techniques for positioning. A receiver measures a time of arrival (ToA) of a positioning reference signal (PRS) transmission of a first PRS sequence transmitted by a first transmitter, measures a ToA of a PRS transmission of a second PRS sequence transmitted by a second transmitter, and determines an observed time difference of arrival (OTDOA) as a difference between the ToA of the PRS transmission of the first PRS sequence and the ToA of the PRS transmission of the second PRS sequence, wherein the OTDOA is less than half a maximum differential delay expected between the PRS transmission of the first PRS sequence and the PRS transmission of the second PRS sequence, and wherein a repetition duration of the first PRS sequence and the second PRS sequence is greater than 10 milliseconds (ms) and at least twice the maximum differential delay.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may receive one or more signals indicating first and second uplink messages that at least partially overlap in time. The first uplink message may be associated with a first set of parameters and a first quantity of antenna ports and the second uplink message may be associated with a second set of parameters and a second quantity of antenna ports. The UE may transmit the first and second uplink messages using a third set of scheduling parameters based on a sum of the first quantity and the second quantity of antenna ports being greater than a quantity of available radio frequency (RF) chains at the UE. The third set of scheduling parameters may be associated with a third quantity of antenna ports that is less than the sum of the first and second quantities.

Abstract: Satellites in a non-terrestrial network may provide positioning reference signals (PRS) to user equipment (UE), with which the UE may determine its position using propagation delay difference measurements, such as Time Difference of Arrival (TDOA) measurement. Due to the large distances between satellites and the UE, the propagation delay differences in the PRS received from satellites may exceed half a radio frame, resulting in a frame level timing ambiguity in the differential measurements. The satellites transmit secondary PRS, along with primary PRS, that include timing information to resolve frame level timing ambiguity of the primary PRS. The positioning occasions in the secondary PRS, for example, may be aligned with corresponding positioning occasions primary PRS within each radio frame, and are transmitted with a periodicity that is an integer multiple (greater than 1) of that of the primary PRS to resolve the frame level timing ambiguity of the primary PRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a high Doppler configuration for UE paging is activated. The UE may detect, based at least in part on receiving the indication that the high Doppler configuration is activated, a phase tracking reference signal (PTRS) for a paging communication. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a resource configuration for a random access (RA) procedure. The resource configuration may identify multiple sets of transmission resources corresponding to multiple radio resource control (RRC) states. The UE may identify an RRC state and may determine a set of transmission resources and/or a transport format based on the indication of the resource configuration, the identified RRC state, and/or a UE identifier (UE ID). The UE may transmit a first RA procedure message (e.g., a msgA) using the determined transmission resources and/or transport format. The base station may receive the message and may identify the RRC state of the UE based on the first message and transmitted indication of the resource configuration. The base station may transmit a second RA procedure message (e.g., a msgB), which the UE may receive.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., non-orthogonal multiple access (NOMA) systems), a base station may serve a large number of user equipments (UEs) on the uplink. To improve detectability for these uplink transmissions (e.g., if reference signals are not available for the transmissions), the UEs may implement parallel transmissions of preambles with uplink data. A UE may split the uplink data into one or more data layers, and may select one or more preamble layers to transmit superposed with the data layers. These preambles may be sequences known to both the UE and the base station to aid in detectability. The UE may assign different signature sequences to each of these layers based on cross-correlation values (e.g., assigning sequences with higher cross-correlation values to the data layers for improved detectability), and may scramble the layers into a single shared signal for transmission.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing remote interference using a previously detected relationship between an aggressor base station and a victim base station. The described techniques provide for allocating reference signal sequences for various victim base stations to send to an aggressor base station. The victim base station may trigger the aggressor base station to perform reference signal monitoring based on the previously detected victim-aggressor relationship, and may transmit a reference signal carrying a unique identifier based on the triggering. The first base station may send a request that the second base station to transmit a reference signal for enabling the first base station to measure interference of a wireless channel, and performing interference mitigation techniques at the first base station, the second base station, or both, to mitigate the remote interference.

Abstract: Various aspects include methods for supporting Enhancement for Television (ENTV) service delivery to a user equipment (UE) in a fifth generation new radio (5G-NR) radio access network (RAN). Various aspects may include generating an ENTV capability message, the ENTV capability message indicating one or more ENTV parameters of the UE, and sending the ENTV capability message to a Next Generation NodeB (gNB) of the 5G-NR RAN. Various aspects may include receiving a ENTV capability message from the UE, the ENTV capability message indicating one or more ENTV parameters of the UE, determining one or more radio resource configurations for the UE based at least in part on the one or more ENTV parameters of the UE, and generating a configuration message indicating the one or more radio resource configurations for the UE, and sending the configuration message to the UE.
