Abstract: Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) may communicate in a high reliability and low latency communications system (e.g., ultra-reliable low latency communications (URLLC)). The base station may signal a UE-specific scheduling request (SR) repetition configuration that the UE may utilize to transmit an instantaneous SR when a buffer status report (BSR) is triggered by a new data packet. The UE may repeatedly transmit the SR until a number of repetitions or a time period of repetitions is met or an uplink grant is received from the base station. The SR repetition configuration may include a number of parameters including a repetition setting, power settings, a resource allocation, and an acknowledgement/negative acknowledgment (ACK/NACK) procedure.

Abstract: Full-duplex communication techniques are described. Some aspects may utilize full-duplex-slot formats, such as may be provided in addition to or in the alternative to uplink, downlink, and flexible slot formats. A full-duplex slot implemented in accordance with a full-duplex-slot format provides a slot in which the frequency band may be used for both uplink and downlink transmissions. Downlink and/or uplink transmissions of a full-duplex slot may occur in overlapping frequency bands or in adjacent frequency bands. A first wireless device may transmit slot signaling comprising one or more full-duplex-slot-indicator parameters. A second wireless device may base one or more full-duplex slot configuration determinations on a full-duplex-slot configuration. The second wireless device may apply one or more full-duplex-slot-indicator-parameter rules with respect to full-duplex-slot-indicator parameters for determining a full-duplex-slot format. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication for a first radio access technology (RAT) has been dynamically scheduled or semi-statically configured, wherein the UE is in a dual connectivity mode using the first RAT and a second RAT. The UE may identify an uplink subframe for transmission of the uplink communication based at least in part on whether the uplink communication has been dynamically scheduled or semi-statically configured, and based at least in part on a downlink-reference uplink-downlink configuration. The UE may transmit the uplink communication in the identified uplink subframe. Numerous other aspects are provided.

Abstract: A user equipment (UE) may be configured to generate a preamble of a first message associated with a random access channel (RACH) procedure, such as a two-step RACH procedure. The UE may be further configured to determine an identifier (ID) associated with the UE based on at least one of an ID associated with the preamble or a port index associated with a demodulation reference signal (DMRS). The UE may generate a payload of the first message that indicates the ID associated with the UE. The UE may then transmit the first message to a base station to initiate the RACH procedure. Potentially, the UE may receive a second message from the base station responsive to the first message, and the second message may confirm the ID associated with the UE.

Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement improved interference tracking over time. A BS may transmit information to a UE that allows the UE to quantize channel measurements into interference states. The UE may transmit an interference change report as triggered by an event, such as an interference metric exceeding a threshold after quantizing into the interference states. This enables the system to capture and respond to abrupt changes. Further, the interference change report may include historic interference information. The UE may include statistics based on the historic interference information. The UE may further be triggered to transmit an interference change report in response to a BS requesting it, or in response to a configured period of time elapsing. The UE may further include MCS information predicted for one or more future time periods based on historic information, which the BS may use in scheduling.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) for multiple transmission reception point (multi-TRP) transmission such as non-coherent joint transmission (NCJT), including determining subband sizes for CSI and rules for Part II CSI omission. A method that can be performed by a user equipment (UE) includes receiving a CSI report configuration. The CSI report configuration associated with one or more CSI reference signal (RS) resources, each CSI resource including a set of ports or port groups. The UE selects one or more CSI-RS resources for which to report CSI and determines a subband size for sending a CSI report based, at least in part, on payload of the CSI report. In an example method, the UE can determine whether the UE has sufficient resources for the CSI report and omit at least a portion of the CSI based on the determination.
