Abstract: Methods, systems, and devices for wireless communication are described that provide for generation of feedback at a code block (CB) level for a received transmission in which a transmit block (TB) includes a number of CBs. The feedback may indicate a request for a retransmission of one or more CBs, and retransmissions of the CBs may be provided at a repetition level that provides multiple repetitions of the one or more CBs. The repetition level may provide for two or more retransmissions of the one or more CBs. In some cases, the repetition level is configurable, and may be based on a number of requests for retransmission that are received. The configuration of repetition levels may be through radio resource control (RRC) signaling, downlink/uplink control information, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a dropping rule relating to: a first triggering communication, of a first transmit receive point (TRP), that triggers a first timeline for a first subsequent communication of the first TRP, and a second triggering communication, of a second TRP, that triggers a second timeline for a second subsequent communication of the second TRP, wherein the dropping rule indicates one or more communications to be dropped when the first triggering communication starts after a start of the second triggering communication and the first subsequent communication starts before a start of the second subsequent communication; and drop the one or more communications based at least in part on the dropping rule. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may report a phase-noise compensation reference signal (PCRS) configuration to a base station to enable per-UE PCRS signaling. For example, a UE may operate in a wireless communications system using carrier frequencies greater than 6 GHz, which may be affected by phase noise. The UE may accordingly determine a PCRS configuration based on a capability to receive signals. The PCRS configuration may include a resource mapping for one or more PCRS, a number of PCRS ports used for PCRS, a multiplexing scheme for one or more PCRS ports, or the UE's phase noise estimation capability. The UE may then transmit a reporting message including the PCRS configuration to a base station. The base station may use the PCRS configuration for PCRS transmissions to the UE.

Abstract: Techniques are described herein for collision handling in uplink transmissions. A user equipment (UE) may have more information to transmit during an uplink transmission than the allocated resources can handle. The UE may identify that an uplink transmission includes a plurality of different channels. The UE may exclude service types or scale the transmit power of service types based on performing a prioritization of the different channels in the uplink transmission. In some cases, the UE may prioritize ultra-reliable low-latency communications (URLLC) service types over enhanced mobile broadband (eMBB) service types. In some cases, the content of the URLLC service types and the content of the eMBB service types may be considered when prioritizing. The UE may be capable of configuring different sets of priority rules based on reliability thresholds and latency thresholds associated with the service types.

Abstract: Various aspects provide for communicating a first set of broadcast reference signals (RSs) in a first subframe that includes a synchronization (SYNC) channel and communicating a second set of broadcast RSs in a second subframe that follows the first subframe. The second subframe may immediately follow the first subframe. A portion of the SYNC channel may include information indicating a configuration of broadcast RSs in one or more other subframes. The brhoadcast RSs may be configured for timing-error estimation, frequency-error estimation, and/or channel estimation. Additional and alternative aspects, embodiments, and features are also provided herein.

Abstract: Transmission time interval (TTI) bundling for ultra-reliable low-latency communication (URLLC) uplink and downlink transmissions is discussed in which a base station or user equipments (UEs) determine conditions for one or more served UEs that would indicate enabling TTI bundling for data and/or control transmissions. The serving base station transmits an enablement signal signifying that TTI bundling will be performed for data and/or control transmissions. The enablement signal may include a bundle length for the transmission bundle. The data or control signal packets may then be repeatedly transmitted to the UEs a number of times corresponding to the bundle length.

Abstract: Methods, systems, and devices for wireless communication are described for dynamic frozen bits of polar codes for early termination and performance improvement. A wireless device may receive a signal comprising a codeword encoded using a polar code. The wireless device may perform decoding of the codeword including at least: parity check of a first subset of decoding paths for making a decision on early termination of decoding of the codeword based on dynamic frozen bits, and generating path metrics for a second subset of the decoding paths that each pass the parity check based on the dynamic frozen bits, and performing error detection on a bit sequence corresponding to one of the second subset of the decoding paths based at part on error detection bits and the generated path metrics. The wireless device may process the information bits based on a result of the decoding.

Abstract: The disclosure relates in some aspects to a scalable transmission time interval (TTI) and hybrid automatic repeat request (HARQ) design. The TTI is scalable to, for example, achieve latency and/or efficiency tradeoffs for different types of traffic (e.g., mission critical traffic versus traffic with more relaxed latency requirements). In the event a longer TTI is employed, various techniques are disclosed for ensuring a fast turn-around HARQ, thereby maintaining a high level of communication performance.

Abstract: Systems and methods for communicating mission-critical (MiCri) data in a network including a base station and user equipment (UE) are provided. The methods may include receiving a request message requesting MiCri data, and transmitting the MiCri data during a transmission time interval (TTI) of a first carrier component or during a transmission time interval (TTI) of a second carrier component. In various aspects, the TTI of the first carrier component may be staggered in time with respect to the TTI of the second carrier component. In another aspect, the UE may pre-report interference pattern information for a nominal TTI for use in communication of MiCri data.
