    Abstract: Wireless communications systems and methods related to reallocating resources assigned to sidelinks are provided. A first user equipment receives a preemption indication from a base station. The preemption indication is for reallocating resources allocated for communication between the first user equipment and the base station and for sidelink communication between the first user equipment and a second user equipment. Based on the preemption indication, the first user equipment reallocates the resources for the communication between the first user equipment and the base station. Based on the preemption indication, the first user equipment reallocates the resources for the sidelink communication between the first user equipment and the second user equipment.

    Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support communication between a base station and a user equipment (UE) during transmission time intervals (TTIs) having different lengths. The techniques described herein allow a UE to utilize appropriate configurations for communicating during a shortened TTI (sTTI) allocated for uplink communication (e.g., uplink control information transmissions). In one example, the UE may adjust a transmit power to use for transmitting uplink control information during an sTTI based on the length of the sTTI or based on the number of symbols allocated for transmitting the uplink control information in the sTTI. In another example, the UE may determine a frequency hopping pattern to use for transmitting uplink control information during an sTTI based on whether a portion of the sTTI is allocated for another transmission (e.g., a sounding reference signal (SRS) transmission).

    Abstract: Methods, systems, and devices for wireless communications are described that support time division duplexing (TDD) for dual connectivity (DC) to different radio access networks (RANs). A DC connection may be established between a user equipment (UE) and both a first RAN and a second RAN. A reference TDD configuration for the first RAN and a designated TDD configuration for both the first and second RAN may be identified. The designated TDD configuration may have a first set of uplink subframes and the reference TDD configuration may have a second set of uplink subframes that is a subset of the first set of uplink subframes. Downlink transmissions of the first RAN may be transmitted according to the reference TDD configuration, and uplink transmissions of the first and second RAN may be transmitted according to the designated TDD configuration.

    Abstract: Methods, systems, and devices for wireless communications are described that support splitting resources among different types of control information and uplink data for transmission on an uplink shared channel. A base station may transmit a grant indicating resource elements (REs) of an uplink shared channel allocated to a user equipment (UE) for an uplink transmission. The UE may process the grant and split the granted REs between different types of uplink control information (UCI) and uplink data based on a reference payload size. The UE may generate an uplink transmission based on the splitting of the REs, and may transmit the uplink transmission in the REs of the uplink shared channel indicated in the grant. The base station may monitor the REs of the uplink shared channel for the uplink transmission in accordance with the splitting of the plurality of REs.

    Abstract: Aspects and techniques relate to scheduling resources for uplink transmissions in wireless communication systems. In some examples, an allocation of resources for uplink may be based on a common reference resource (e.g., a reference physical resource block, PRB) also used for allocation of resources for downlink In other examples, allocation of resources for uplink may be based on a different reference resource. A scheduler may further provide an indication whether the same, common reference resource is used, or a different reference resource. A scheduler may further indicate a different reference resource as needed. Other aspects, embodiments, and features are also claimed and described.

    Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive scheduling information for a transmission associated with a particular radio access technology (RAT) of a 4G RAT or a 5G RAT, wherein the scheduling information identifies a particular resource of one of a first set of resources for the 4G RAT or a second set of resources for the 5G RAT, wherein one or more resources of the first set of resources are guaranteed for the 4G RAT based at least in part on a reference 4G time division duplexing (TDD) configuration, and wherein the one or more resources of the first set of resources and the second set of resources do not overlap in a time domain; and transmit or receive the transmission using the particular resource. Numerous other aspects are provided.
