Abstract: Methods, systems, and devices for sidelink wireless communications are described in which a transmitting device may determine a transport block size (TBS) for a sidelink data channel transmission and provide an indication in in sidelink control information (SCI) to allow a receiving device to determine the TBS to be used for decoding the sidelink communication. The indication provided in the SCI may be an explicit indication in an information element that indicates whether feedback channel resources are included or excluded when determining a number of symbols for use in a TBS determination. The indication provided in the SCI may also be an implicit indication based on one or more values of one or more parameters provided in the SCI. The sidelink communications devices may determine a same TBS across multiple instances of a sidelink data channel transmission that may be transmitted using slots having different slot formats.

Abstract: In a particular implementation, a method of wireless communication includes transmitting, from a first user equipment (UE) to a second UE, a radio resource control (RRC) request that includes a first discontinuous reception (DRX) preference at the first UE. The method also includes receiving, at the first UE from the second UE, a RRC setup message that includes a second DRX preference at the second UE. The method further includes transmitting, from the first UE to the second UE, a RRC setup complete message that includes an indication of a confirmed DRX cycle.

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. The described techniques relate to the categorization of resources in a system to enable a user equipment (UE) to determine whether resources may be reclaimed. At least two categories may be defined for the resources, and the UE may use various criteria for categorizing the resources in a system. For example, the UE may include a first set of resources in an “available” category and a second set of resources in an “occupied” category. Resources in the “occupied” category may be indicated as occupied by another UE's sidelink channel information. In cases where resources are indicated as reserved for retransmission by another UE, but no feedback is detected, then the UE may use additional parameters to determine whether those resources may be reclaimed for its own transmission and may categorize the resources accordingly.

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: Methods, systems, and devices for wireless communications are described, in which a user equipment (UE) may communicate with one or more other UEs using sidelink communications. Multiple UEs may form a sidelink communications group and provide for sidelink groupcast communications in which an identification of a UE is determined based at least in part on a member identification of the UE within the group. Each UE in the group may determine feedback resources for acknowledgment feedback within the group based on a UE identification and a size of the group.

Abstract: Wireless communications systems and methods related to sidelink communications in a TDD system are provided. A first user equipment (UE) may receive from a base station (BS), a time-division-duplexing (TDD) configuration. The first UE may select a first TDD configuration from a set of configured TDD configurations based on the TDD configuration. Additionally, the first UE may transmit to a second UE, an indication of the first TDD configuration. The first and the second UEs may communicate a sidelink communication based on the first TDD configuration. Other features are also claimed and described.

Abstract: Techniques are described for wireless communication. One method includes identifying a set of punctured bit locations in a received codeword. The received codeword is encoded using a polar code. The method also includes identifying a set of information bit locations of the polar code, with the set of information bit locations being determined based at least in part on polarization weights per polarized bit-channel of a polar code decoder that are a function of nulled repetition operations per polarization stage of the polar code identified based at least in part on the set of punctured bit locations. The method further includes processing the received codeword using the polar code decoder to obtain an information bit vector at the set of information bit locations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first downlink control information (DCI) at a first time, and may receive a second DCI at a second, later time. Each DCI may contain scheduling information for scheduling a number of transmissions at the UE. A transmission associated with the first DCI on a first cell may be scheduled to start before or during a transmission associated with the second DCI on a second cell. The UE may then determine priorities associated with the first and second cells. In cases where the priority of the second cell is greater than the priority of the first cell, the UE may transmit the second scheduled transmission before it transmits the first scheduled transmission. As a result, the UE may prioritize transmitting the second scheduled transmission before the first scheduled transmission.
