Abstract: A first apparatus may puncture, in at least two subslots, a first type of data or control information with a second type of data or control information. The first apparatus may bundle the least two subslots within a subframe, and the subframe may include a portion for carrying acknowledgment (ACK)/negative acknowledgment (NACK) information associated with the second type of data or control information. The first apparatus may communicate with a user equipment (UE) during the at least two subslots within the subframe. A second apparatus may receive ACK/NACK information associated with a second type of data or control information. The second apparatus may reduce a transmission power for a first type of data or control information during a subsequent subframe when the ACK/NACK information indicates a negative acknowledgement.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a configuration of a radio link monitoring resource for a radio link that transports downlink traffic for a first type of service, the first type of service having a higher reliability specification and a lower latency specification than a second type of service offered by the base station. The UE may receive the configuration, and detect that the radio link satisfies a failure condition for the first type of service based on monitoring the RLM resource. The UE may transmit a radio link failure (RLF) indication for the first type of service to the base station based on detecting that the radio link satisfies the failure condition for the first type of service. The base station may receive the RLF from the UE, and transmit an RLF response to the UE.

Abstract: Wireless communication devices are adapted to employ Golay-based matrices for encoding a wireless transmissions. According to at least one example, a wireless communication device can identify an information vector to be transmitted as a wireless communication. A Golay-based generator matrix may be selected based on a length of the information vector, where the selected Golay-based generator matrix is generated by shortening a Golay generator matrix by removing a plurality of columns of systematic bits and a plurality of rows to obtain the shortened generator matrix, and extending the shortened generator matrix to obtain an extended generator matrix by adding columns to at least the systematic bits and appending rows to obtain a desired matrix size. A respective bit value may be determined for bits in each added column and for at least some of the bits in each appended row. Other aspects, embodiments, and features are also included.

Abstract: Aspects of the present disclosure describe an indication channel for wireless communications that indicates whether an ultra-reliable low-latency communication (URLLC) transmission is present in an enhanced mobile broad band (eMBB) slot. A user equipment (UE) may receive an indication channel identifying one or more resources defined by time domain parts and frequency domain parts that have been punctured by an Ultra-Reliable Low latency Communication (URLLC) transmission. The number of frequency domain parts may be greater than or equal to two. The UE may determine a number of resource block groups (RBGs) in an active band width part (BWP) of the UE. The UE may map the RBGs in the BWP among each of a number of sub-bands equal to the number of frequency domain parts based on a pre-defined rule.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine to block puncture or to block shorten a set of transmitted bits of an adjusted fractally enhanced kernel polar code for a communication of an incremental redundancy (IR)-hybrid automatic repeat request (HARQ) process based at least in part on a code rate associated with the communication of the IR-HARQ process. The wireless communication device may generate the adjusted fractally enhanced kernel polar code for the communication based at least in part on determining to block puncture or to block shorten the set of transmitted bits. The wireless communication device may transmit the communication using the adjusted fractally enhanced kernel polar code. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple physical downlink control channels (PDCCHs) in one or more slots along with data traffic, where one of the PDCCHs includes a downlink preemption indication (DLPI) signifying that a portion of the data traffic was preempted. In some cases, the UE may monitor, within a same slot, for both the data traffic and an additional PDCCH carrying the DLPI and then transmit, within the same slot, a feedback message based on attempting to decode the data traffic, taking into account the DLPI. Additionally, the UE may receive the data traffic via a first service, where the DLPI indicates a second service preempts the first service. In some cases, the DLPI may be transmitted based on the UE being capable of processing the data traffic and transmitting the feedback message within the same slot.

Abstract: Various aspects described herein relate to communicating hybrid automatic repeat/request (HARQ) feedback. A HARQ communication can be received over a set of one or more links based on a first scheduling grant. HARQ feedback for the HARQ communication including at least one of HARQ feedback for one or more of the set of one or more links can be transmitted.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may determine that a serving base station supports multi-code and single-code transmissions, receiving a scheduling message having a cyclic redundancy check scrambled with a radio network temporary identifier (RNTI), determine resources for communicating with the serving base station based on the scheduling message, and communicate on the resources using coding associated with the single-code transmissions. A base station may identify at least one user equipment that supports single-code transmissions, transmit a scheduling message having a cyclic redundancy check (CRC) scrambled with a radio network temporary identifier (RNTI), wherein the scheduling message schedules the at least one user equipment for communication on resources using coding associated with the single-code transmissions and communicate with the at least one user equipment on the resources using the coding.

Abstract: Aspects of the present disclosure provide a code block group (CBG) based HARQ retransmission process in which HARQ retransmission is performed based on CBG units. The CBG based HARQ process uses a CBG failure mask that can reduce the signaling overhead of CBG-based HARQ retransmissions. A base station can determine the error CBGs from different UEs that share a slot, and generate a CBG failure mask that capture all the CBGs NACKs from the UEs.
