Abstract: A transmitting device may identify a set of bit locations of a polar code for encoding an input vector based at least in part on a reliability order of the bit locations, where the input vector includes a set of payload bits. The transmitting device may map bits of the input vector to respective bit locations of the identified set of bit locations and may apply a masking operation to a subset of bits of the input vector that is mapped to a most reliable subset of the set of bit locations. The transmitting device may perform an encoding operation according to the mapped input vector to generate a codeword for transmission. A receiving device may perform complementary operations to obtain the payload bits of the input vector. Based on the described techniques, a false alarm rate for the receiving device may be suppressed.

Abstract: A technique for hybrid automatic repeat request (HARD) transmissions using low-density parity-check (LDPC) coding with self-decodable retransmissions is disclosed. Data is encoded using a low-density parity check code to obtain encoded data, where the encoded data includes core data and non-core data. The encoded data is then stored in a buffer for transmission. A plurality of redundancy versions of the encoded data is then transmitted, wherein all redundancy versions of encoded data include core data, and each of the transmitted redundancy versions of the encoded data includes at least a different subset of the core data. The core data may be reordered prior to obtaining at least one of the different subsets of core data. Each of the transmitted redundancy versions of the encoded data includes sufficient core data to permit self-decodability of the transmission at a receiver.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE), may identify a default modulation and coding scheme table and a preconfigured modulation and coding scheme table associated with a resource pool. The UE may receive, from a transmitting communication device, an indication of the preconfigured modulation and coding scheme table to use for upcoming sidelink communications. The UE may then communicate based on the preconfigured modulation and coding scheme table.

Abstract: The techniques described herein provide procedures at user equipment (UEs) for performing channel state information (CSI) reporting and sounding reference signal (SRS) transmissions based on an ultra-reliable low latency communication (URLLC) block error rate (BLER) target and for reliably receiving PDCCH transmissions. For CSI reporting, a UE may be configured to generate a CSI report based on a BLER target and on received CSI reference signals (CSI-RSs), where the CSI-RSs may be transmitted on one or more groups of quasi co-located antenna ports. For SRS transmissions, a UE may be configured to transmit SRS based on an SRS configuration determined based on a BLER target. For receiving PDCCH transmissions, a UE may be configured to receive and combine DCI received from multiple base stations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of one or more sidelink resources, and the UE may identify wake-up signal occasions associated with the resources. The UE may monitor for wake-up signals during the wake-up signal occasions, and the UE may further monitor the associated set of one or more resources based on receiving a wake-up signal. In some examples, respective sets of one or more sidelink resources may be associated with a number of multiple-input multiple-output layers used for sidelink communications, or may indicate respective bandwidth parts used for monitoring sidelink transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a device, such as a user equipment (UE), may receive, from one or more base stations during a first time unit, a control signal including an indication of a reference signal bundling configuration associated with one or more physical channel types which may be potentially scheduled during a set of time units after the first time unit. The UE may determine the set of time units based on the indication of the reference signal bundling configuration. Additionally or alternatively, the UE may receive scheduling configuration of one or more physical channels, and the one or more physical channels during one or more second time units of the set of time units. The UE may then bundle the one or more physical channels based on the reference signal bundling configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive downlink control information corresponding to a transmission of a transport block over a plurality of transmission time intervals (TTIs). The wireless device may identify a redundancy version sequence for the transport block. The redundancy version may be a pre-defined sequence or may be configured by higher layer signaling based on sequence criterion. The wireless device may transmit or receive a plurality of redundancy versions of the transport block in the plurality of TTIs based at least in part on the redundancy version sequence. In some examples, the plurality of redundancy versions may be determined based at least in part on a starting redundancy version identified by another wireless device.

Abstract: Wireless devices may employ techniques for indicating alternative modulation coding schemes (MCSs) (e.g., MCS values or MCS indices not associated with a default list or default MCS table). That is, communications (e.g., such as physical downlink control channel (PDCCH) transmissions carrying downlink control information (DCI), physical downlink shared channel (PDSCH) transmissions carrying uplink grants, etc.) may include information (e.g., in MCS fields and reserved fields) that indicate alternative MCSs for subsequent communications. For example, random access radio network temporary identifier (RA-RNTI) scrambled DCI, random access response (RAR) messages, etc., may indicate an alternative MCS for subsequent messages in a random access procedure (e.g., for a RAR, an RRC connection request, etc.). The alternative MCS may be conveyed by indicating information such as MCS scaling factors, alternative MCS table IDs, MCS indices associated with the alternative MCS table, or some combination thereof.

Abstract: Wake-up signal (WUS) downlink control information (DCI) may be configured to convey a wake-up indication as well as UE wake-up behavior configuration information. For example, WUS DCI may include one or more wake-up indications for one or more UEs via wake-up indication bits (e.g., wake-up indication bits may be conveyed in locations of the WUS DCI associated with monitoring indices of the one or more UEs to be activated). For example, WUS DCI may be encoded to include a wake-up indication and an indication of behavior configuration information for a group of one or more UEs. UE wake-up behavior configuration information may indicate some BWP to activate, may trigger a CSI report, etc. A UE may decode the wake-up indication and the wake-up behavior configuration information based on a monitoring index and the WUS configuration.
