    Abstract: Systems and methods configured to provide size matching of downlink control information (DCI) formats to restrict a number of DCI format sizes for a set of DCI formats for concurrent use are described, in accordance with embodiments of the present disclosure, size matching at least two DCI formats of a set of DCI formats to restrict a number of DCI format sizes for the set of DCI formats for concurrent use is implemented. Restrictions with respect to the number of DCI format sizes for the set of DCI formats may correspond both to a first number of DCI sizes parameter based on a total number of DCI format sizes per wireless communication slot, and to a second number of DCI sizes parameter based on a total number of DCI format sizes for DCI formats used to carry DCI payload encoded using an identifier per wireless communication slot.

    Abstract: Physical random access channel (PRACH) configuration on new radio unlicensed (NR-U) networks is disclosed. A UE may perform PRACH transmission either with a transmission opportunity (TXOP) or outside of a TXOP. The UE monitors for a control signal from a base station, such as a preamble or common control signal, identifying a TXOP. The UE may obtain an autonomous random access configuration for communications outside of the current TXOP that identifies a random access slot includes a plurality of random access occasions. If the UE fails to detect the control signal, it transmits an autonomous random access signal in a random access occasion corresponding to a beam direction of its location in relation to the base station. Otherwise, upon detection of the control signal and receipt of a trigger signal, the UE may transmit a random access request within the TXOP.

    Abstract: This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.

    Abstract: Synchronization signal block (SSB) multiplexing and remaining material system information (RMSI) monitoring in new radio unlicensed (NR-U) networks are disclosed. For SSB multiplexing, a user equipment (UE) receives an SSB configuration for a discovery signal detection window having a plurality of communication slots, wherein, based on the SSB configuration, UE identifies random access resource and time and frequency locations to monitor remaining minimum system information (RMSI) configured for each SSB. The UE further receives an SSB transmission indicator that reflects a listen before talk (LBT) result, which it may use with the SSB configuration to map one or more SSB for rate matching in selected slots. The UE can then rate match any data transmissions around the identified SSBs in those identified slots regardless of LBT result. The UE may further leverage the SSB configuration and indication of LBT result to monitor SSB transmissions for control resource set (CORESET) transmissions.

    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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a reference signal preemption scheme associated with one or more reference signal resources being preempted for priority transmissions during a time period. The UE may determine that resources of one or more reference signals have been preempted during the time period and in accordance with the reference signal preemption scheme. The UE may implement a reference signal preemption response scheme that is selected based at least in part on the resources of the one or more reference signals being preempted.

    Abstract: Methods, systems, and devices for wireless communications are described. A method may include receiving, from a base station and while being outside of a radio resource control (RRC) connected state, an indication of a length of downlink symbols used to transmit a physical downlink shared channel (PDSCH) that carries broadcast information, and decoding the PDSCH based on the indication. Another method may include receiving, from a base station, a PDSCH that carries broadcast information over a plurality of downlink symbols and while being outside of an RRC connected state, perform a first blind decoding of the PDSCH over a first set of the plurality of downlink symbols, and perform a second blind decoding of the PDSCH during a second set of the plurality of downlink symbols, the second set being different in length than the first set.
