Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may construct, for adjusted fractally enhanced kernel (FRANK) polar coding, encoding code for encoding data of an ultra-reliable low latency (URLLC) communication, wherein an information bit assignment to an information bit set associated with the encoding code is performed based at least in part on an adjusted dimensionality factor, wherein the encoding code is all-stage FRANK polar code or partial-stage FRANK polar code, and wherein the encoding code is constructed for code block shortening or code block puncturing. In some aspects, the user equipment may transmit the URLLC communication encoded using the encoding code based at least in part on the information bit assignment to the information bit set. Numerous other aspects are provided.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine at least one of a downlink path loss value or an uplink path loss value associated with a base station; receive system information, a semi-persistently configured grant via RRC or a dynamic uplink grant via DCI from the base station, wherein the RRC signaling or the dynamic uplink grant identifies a power control value associated with one user or a plurality of users associated with the base station; and determine a transmit power for a data or control transmission based at least in part on at least one of the downlink path loss value or the uplink path loss value and the power control value. Numerous other aspects are provided.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a size of an uplink control information (UCI) part exceeds a UCI part payload size limit, wherein the UCI part includes hybrid automatic repeat request acknowledgment information (HARQ-ACK), and may selectively transmit the UCI part based at least in part on determining that the size of the UCI part exceeds the UCI part payload size limit.

Abstract:
Certain aspects of the present disclosure provide techniques and apparatus for determining a modulation and coding scheme (MCS) and channel quality indicator (CQI) for ultra-reliable low latency communications (URLLC). An exemplary method generally includes receiving a channel quality indicator (CQI) from a user equipment (UE) and retrieving parameters from a modulation and coding scheme (MCS) table using the CQI, wherein the table has entries corresponding to different spectral efficiency (SE) values selected to allow the BS to efficiently allocate resources at low SE values to achieve at least a target block error rate (BLER). The method also includes sending a transmission to the UE based on the retrieved parameters.
Abstract:
Implementations of the technology described herein provide adjustment to the time-of-departure (ToD) of the start of the acknowledgement frames (ACK) based on the time-of-arrival (ToA) estimation and correction of their corresponding message frames to keep the turnaround time of the acknowledgement frames stable to a predefined order of precision, with special applications for Wi-Fi ranging to achieve double-sided time-of-arrival (ToA) correction accuracy with minimal frame exchanges. A receiving station uses its time-of-arrival (ToA) correction to adjust the transmission time of an acknowledgement message (ACK) so that both the sending station and the receiving station can estimate round trip time (RTT) (or perform ranging) at the same level or higher accuracy.
Abstract:
Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to establish a data session with a base station. The UE may transmit one or more session request messages including one or more route selection descriptors (RSDs) to the base station, and the UE may determine a successful RSD that may be compatible with the network based on a session accept message received from the base station. The UE may store the successful RSD at a location in memory for use in future session establishment procedures. For example, the UE may go out of service, and may re-acquire service with the same network. In such cases, the UE may transmit a session request message including the previously-accepted RSD to re-establish a data session with the base station.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission power for an uplink shared channel communication based at least in part on at least one of a code rate parameter, a block length parameter, or a target block error rate parameter associated with the uplink shared channel communication. In some aspects, the user equipment may transmit the uplink shared channel communication using the transmission power based at least in part on determining the transmission power.
