Abstract: Wireless communications systems and methods related to monitoring a paging signal are provided. A wireless communication device may receive a first system information signal from a base station (BS) and may configure a counter with an initial counter value in response to receiving the first system information signal. Additionally, the wireless communication device may receive a second system information signal from the BS and may modify the counter value of the counter in response to receiving the second system information signal. The wireless communication device may monitor for a paging signal from the BS while the counter is outstanding.

Abstract: Wireless communications systems and methods related to communications in a network that supports data transmitted in an unlicensed frequency band and a licensed frequency band are provided. A first wireless communication device communicates, with a second wireless communication device, a configuration indicating a first resource in an unlicensed frequency band and a second resource in a licensed band. The first wireless communication device communicates, with the second wireless communication device in the unlicensed frequency band, a first communication signal based on the configuration. The first wireless communication device communicates with the second wireless communication device in the licensed frequency band, a second communication signal based on at least one of a channel status of the unlicensed frequency band or a transmission parameter associated with at least one of the first communication signal or the second communication signal.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for encoding uplink data for transmission based on control information included in a first uplink grant corresponding to a first set of uplink resources, receiving a second uplink grant associated with a second set of uplink resources, wherein the second uplink grant is associated with the encoded uplink data for transmission, determining a starting time (e.g., a first delay or a second delay) for the second set of uplink resources based at least in part on a timing of the encoding with respect to the second uplink grant, and transmitting uplink data during the second set of uplink resources based on the determined starting time.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a grant scheduling a downlink transmission of a set of configurable downlink transmissions. The downlink transmission may include reference slots corresponding to offset values associated with one or more feedback occasions. The UE may construct a feedback codebook based on a first quantity of slots in the set of configurable downlink transmissions, a second quantity of reference slots in the set of configurable downlink transmissions, and a third quantity of configurable offset values associated with one or more feedback occasions. Based on a size of the feedback codebook, the UE may generate feedback bits for reporting whether the UE successfully received a downlink transmission in corresponding slots. In some examples, the UE may identify a slot with a symbol reserved for an uplink transmission, and skip generating a corresponding feedback bit for the identified slot.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.

Abstract: Methods, systems, and devices for wireless communications at a device are described. The device may receive an indication of a configuration that schedules semi-persistently scheduled resources for transmissions from the first device. The device may also receive an indication of a set of resources available to the first device for requesting a set of the semi-persistently scheduled resources configured for the first device. The device may transmit a message over the set of resources to request the set of semi-persistently scheduled resources.

Abstract: Autonomous uplink (AUL) for wideband new radio (NR) unlicensed (NR-U) operations is disclosed. For user equipments (UEs) that have been configured for AUL transmissions and have received an activation signal to activate the AUL capabilities, further indications may be used to enable AUL transmissions on AUL transmission opportunities (TxOPs) that overlap the timing of a current TxOP reserved by a serving base station, but that are allocated outside of the resources reserved for the current TxOP. A UE that identifies a desired, next AUL TxOP that overlaps the current base station-initiated TxOP duration, but is allocated for resources outside of the current TxOP resources determines whether it has obtained an enablement indication either directly from the serving base station or implicitly, based on current conditions at the UE. When the UE determines that it has obtained an enabling indication, it may then perform AUL transmissions via the overlapping AUL TxOP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may be configured to monitor a first set of decoding candidates within a first search space for receiving a physical downlink control channel message. A base station may identify downlink data for the user equipment and may transmit a signal to the user equipment. The user equipment may receive the signal within the first search space. In some cases, the signal may include a command for activating a second search space. The user equipment may monitor a second set of decoding candidates within the second search space based on receiving the signal. The user equipment communicate, with the base station, based on monitoring the first set of decoding candidates within the first search space and the second set of decoding candidates within the second search space.

Abstract: Code block group (CBG) transmission indications for communications configured with multiple transmission time interval (TTI) grants is disclosed. Where multiple TTIs are configured for CBG transmission, the base station may select to signal CBG transmission indications and/or transport block (TB)-level new data indicator (NDI) for each of the configured TTIs along with an index of the TTIs that CBG transmission indicators are sent for. The base station may select to add one or more CBG transmission indications based on the predetermined payload size of the transmission indication signal of the physical downlink control channel (PDCCH).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a message to a transmission reception point (TRP) in a multi-TRP network that indicates a capability of the UE to support a communication scheme (e.g., a spatial division multiplexing (SDM) scheme, a single frequency network (SFN) scheme, a combined SDM and SFN scheme, or the like). The UE may receive a configuration that indicates parameters common to both the SDM scheme and the SFN scheme. The TRP may transmit an indication of an SDM scheme, an SFN scheme, a combined SDM and SFN scheme, or the like to the UE for communications between the UE and one or more TRPs. The UE may communicate with the one or more TRPs based on the communication scheme indicated by the TRP.
