Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical random access channel (PRACH) preamble configuration that indicates a first preamble format for a first PRACH preamble and a second preamble format for a second PRACH preamble, wherein the first preamble format is different from the second preamble format. The UE may transmit the first PRACH preamble as part of a random access procedure based at least in part on the PRACH preamble configuration, wherein transmitting the first PRACH preamble enables a determination of a symbol boundary offset. The UE may transmit the second PRACH preamble as part of the random access procedure based at least in part on the PRACH preamble configuration, wherein transmitting the second PRACH preamble enables a determination of a symbol timing offset. Numerous other aspects are described.

Abstract: Various aspects relate generally to the beam management procedures in wireless communications systems. Some aspects more specifically relate to the selection of beams for communications to and from a UE and a network entity based on quantized orientation information for a user equipment (UE). In some implementations, a network entity can use the quantized orientation information and a machine learning model to predict a set of beams that may be suitable for communications to and from the UE and the network entity, which may be a subset of the beams that the network entity can generally use for communications to and from the UE and the network entity.

Abstract: A non-terrestrial network is provided that includes a satellite that transmits an orbital parameter message to a user equipment. The user equipment processes the orbital parameter message to determine a current range from the user equipment to the satellite based upon the received orbital parameter message, a timing offset and a frequency offset for an uplink transmission to the satellite.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first downlink control information (DCI) scheduling a downlink transmission at the UE, where the first DCI includes an indication of a first resource allocation for the downlink transmission. The UE may determine that the downlink transmission includes a downlink data message multiplexed with second DCI. The UE may receive an indication of a second resource allocation for the second DCI. The UE may determine a transport block size (TBS) of the downlink data message based on the first resource allocation for the downlink transmission and the second resource allocation for the second DCI. The UE may then process the downlink transmission based on the TBS of the downlink data message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration of a set of synchronization signal blocks (SSBs) to be transmitted by a first base station or a second base station. In some cases, the UE may be served by the first base station and the UE may receive, from the first base station or the second base station, a message indicating that a transmission of at least one SSB of the set of SSBs is canceled and indicating resources for a signal (e.g., a reference signal, alternative SSB transmission) to be transmitted by the first base station or the second base station as an alternative to the canceled at least one SSB. The UE may receive, based on the received message from the first base station or the second base station, the signal using the indicated resources.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify, for a user equipment (UE), a configuration for receiving a set of downlink control information (DCI) messages on one or more layers of a set of layers of a downlink shared channel. The base station may transmit, to the UE, a first DCI message in a downlink control channel, where the first DCI message may schedule resources of the downlink shared channel for the set of piggybacking DCI messages. The UE may receive the first DCI message and identify the configuration for receiving the set of DCI messages on the one or more layers of the downlink shared channel. The UE may receive, from the base station, the set of DCI messages on the one or more layers of the downlink shared channel based on the identified configuration.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive, from a base station, a first downlink control information message in a downlink control channel, the first downlink control information message scheduling first resources of a downlink shared channel for a second downlink control information message. The UE may identify a first, UE-specific scrambling sequence for the second downlink control information message. The UE may receive, from the base station, the second downlink control information message based on the first scrambling sequence, the second downlink control information message scheduling second resources of the downlink shared channel for a data message. The UE may receive, from the base station, the data message in the second resources scheduled by the second downlink control information message.

Abstract: A non-geosynchronous satellite system, where each satellite has an antenna (perhaps a multi-element antenna) to form a beam pattern comprising a set of beams in the footprint of the satellite, where in one implementation each beam is substantially elliptical in shape having a minor axis and a major axis, where the minor axes are substantially collinear and the major axes are substantially oriented east to west. For a satellite, power is reduced or turned off for a subset of the set of beams, wherein each beam in the subset is reduced at or below a corresponding power level such that when a beam is powered above its corresponding power level an equivalent power flux-density (EPFD) exceeds a limit at some point on the Earth's surface.
