Abstract: According to some aspects of the disclosure, techniques for compression techniques for the radar data that can be used in real-time applications for automated or self-driving vehicles. One or more compression techniques can be selected and/or configured based on information regarding operational conditions provided by a central (vehicle) computer. Operational conditions can include environmental data (e.g., weather, traffic), processing capabilities, mode of operation, and more. Compression techniques can facilitate transport of compressed radar data from a radar sensor to the central computer for processing of the radar data for object detection, identification, positioning, etc.

Abstract: A user equipment (UE) may communicate with a base station through a first active beam, the first active beam comprising a serving beam. The UE may receive a first reference signal and a second reference signal associated with beam tracking from the base station, where the first reference signal is received through a first beam of a first plurality of beams and the second reference signal is subsequently received through a second beam of a second plurality of beams, and where the beam tracking includes identifying a new beam for communication between the UE and the base station. The UE may communicate with the base station through a second active beam based on at least one of the first reference signal or the second reference signal associated with the beam tracking, the second active beam comprising the new beam.

Abstract: In millimeter wave systems, user equipment may not be able to receive RACH parameters through a PDCCH when the information is transmitted with an omni-directional beam. In an aspect of the disclosure, an apparatus, such as a base station, may determine the RACH parameters and transmit a subset of the RACH parameters via a PBCH. The user equipment may receive the RACH parameter subset and initiate a RACH procedure.

Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.

Abstract: A node for wireless communication identifies a number of actually transmitted reference signals. The node identifies a number of available PRACH time-frequency resources and preamble indices in a time period. The node identifies a number of configured PRACH time-frequency resources or PRACH preamble indices per reference signal. The node determines that the available number of PRACH time-frequency resources or PRACH preamble indices within the time period is not an integer multiple of the product of the number of actually transmitted reference signals and the number of configured PRACH time-frequency resources or PRACH preamble indices per reference signal. The node maps the actually transmitted reference signals to the available PRACH time-frequency resources and preamble indices based on the identified information and determination.

Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication with a network. In some aspects, the scheduled entity transmits a message that requests a scheduling entity to transmit at least one reference signal. The scheduled entity obtains channel state information based on the at least one reference signal. The scheduled entity transmits a report that includes the channel state information. In other aspects, the scheduled entity transmits a message that requests a scheduling entity to schedule a reference signal transmission for the scheduled entity. The scheduled entity obtains an assignment of resources for transmission of the reference signal in response to the message. The scheduled entity transmits the reference signal based on the assignment of resources. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine a transmission configuration for a first random access message based at least in part on one or more parameters associated with a target base station for initiating a backhaul connection. The transmission configuration may include information associated with a physical random access channel (PRACH) resource associated with transmitting the first random access message. The PRACH resource differs from a PRACH resource associated with a transmission of a random access message by a user equipment. The base station may transmit the first random access message using the transmission configuration. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for beam refinement. A base station provides information regarding what transmit beams are used to transmit different reference signal (RS) resources. In some cases, the information indicates whether a same transmit beam is used to transmit a set of RS resources (e.g., symbol, sub-symbol, or frequency resources) or whether different transmit beams are used to transmit the set of RS resources.
