Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. The techniques include a method wireless communication by a user equipment including receiving a configuration message, wherein the configuration message in part configures the UE to communicate coordinated transmissions with a plurality of transmission reception points using a coordinated transmission mode. The method further includes, receiving one or more physical downlink shared channel transmissions from a plurality of transmission reception points in accordance with the coordinated transmission mode. The method further includes, selecting a HARQ-ACK feedback mode based in part on the coordinated transmission mode. The method further includes, transmitting HARQ-ACK feedback to at least one of the plurality of transmission reception points using the selected HARQ-ACK feedback mode.

Abstract: Disclosed are techniques for signaling of reception-to-transmission measurements from gNBs and user equipments (UEs) for round trip time (RTT) based positioning in wireless networks such as new radio (NR). In multi-RTT positioning, the flow of messages that are exchanged differ depending on the entity acting as the location server determining the position of the UE.

Abstract: Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Abstract: Configurations and feedback schemes for compressed channel state information (CSI) feedback are provided. A User Equipment (UE) determines a constraint on a total number of transfer domain coefficients to be reported for compressed Channel State Information (CSI) feedback by the UE for a plurality of beams identified for the feedback, wherein each transfer domain coefficient is associated with amplitude information and phase information. The UE selects from a transfer domain coefficient compression matrix, based on the constraint, a set of one or more transfer domain coefficients to report for each of the beams. The UE reports information indicating a number of selected transfer domain coefficients in the set of transfer domain coefficients for each beam and a location of each transfer domain coefficient within the transfer domain coefficient compression matrix and reports at least the amplitude and phase information for the selected coefficients.

Abstract: A method performed by a communication device includes generating an initial channel estimate of a channel for a current time step with a Kalman filter based on a first signal received at the communication device. The method also includes inferring, with a neural network, a residual of the initial channel estimate of the current time step. The method further includes updating the initial channel estimate of the current time step based on the residual.

Abstract: The disclosure relates in some aspects to information encoding. Information encoding may involve puncturing bits of a codeword or repeating bits of a codeword. The disclosure relates in some aspects to selecting a puncturing or repetition pattern. In some aspects, a puncture pattern for data encoding is selected based on a criterion that the output and the repetition input of an XOR are not erased. In some aspects, a repetition pattern for data encoding is selected based on a criterion that repetition not be applied for the output and the repetition input of an XOR.

Abstract: Aspects directed towards new radio (NR) transmissions of uplink control information (UCI) are disclosed. In a particular example, a priority is assigned to each of a plurality of UCI components such that the priority is assigned according to at least one of a type or payload size respectively associated with each of the plurality of UCI components. The plurality of UCI components are then transmitted based on the priority respectively assigned to each of the plurality of UCI components.
