    Abstract: In embodiments of systems and methods for managing control signaling for multicast communications, a base station may transmit to a wireless device an indication of whether to monitor a group common physical downlink control channel (GC PDCCH), a wireless device-specific PDCCH for multicast configuration information, or both. The base station may determine a schedule for transmitting multicast communications to the wireless device based on a capability reported by the wireless device, and may transmit to the wireless device an indication of whether a transport block for GC multicast communications including services for multicast communications will be scheduled by the GC PDCCH, the wireless device-specific PDCCH, or both. The base station may transmit, and the wireless device may receive, the multicast communications according to the multicast configuration information and the schedule.

    Abstract: Methods, systems, and devices for wireless communication are described. In one example, a method for wireless communication at a user equipment (UE) includes identifying that the UE is in carrier aggregation communication with a first cell having a first sub-carrier spacing and a second cell having a second, different sub-carrier spacing. The method may further include monitoring one or more UE-specific search spaces of the first cell for first control information scheduling a first data communication on the first cell and one or more UE-specific search spaces of the first cell or the second cell for second control information scheduling a second data communication on the first cell, and resolving a scheduling order of the first control information scheduling the first data communication and the second control information scheduling the second data communication based at least in part on the monitoring and on a scheduling condition.

    Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for performing rate matching for a physical downlink shared channel (PDSCH). An example method generally includes monitoring for at least first and second downlink control information (DCI) formats for scheduling a physical downlink shared channel (PDSCH), determining a bitwidth of a rate matching indicator field of at least one of the first DCI format or the second DCI format, and performing PDSCH rate matching for a PDSCH scheduled by a DCI of the first or second DCI format based, at least in part, on the rate matching indicator field in the DCI or a format of the DCI.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure an outer coded block which a user equipment (UE) may implement to recover an unsuccessfully decoded transmission. The base station may send, to the UE, downlink control information (DCI) indicating an outer coding scheme for the group of data blocks (e.g., a first data block and a second data block). The UE may monitor for the data blocks and the outer coded block. The UE may decode the data blocks based on the outer coded block and the outer coding scheme. In some examples, the outer code block may be made up of a combination of the first and second data blocks. The UE may use the combination of the outer coded block and one of the data blocks to decode an unsuccessfully decode data block.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling indicating a group of transmission configuration indicator states including a first subset associated with a first bandwidth part and a second subset associated with a common frequency resource. The UE may determine, based on the group of transmission configuration indicator states, a transmission configuration indicator state list arrangement indicating a first state list associated with the first bandwidth part and a second state list associated with the common frequency resource. The UE may select, based on the transmission configuration indicator state list arrangement, a transmission configuration indicator state sharing scheme or a transmission configuration indicator state separation scheme. The sharing scheme may include at least one transmission configuration indicator state that may be common between a unicast transmission configuration and a multicast transmission configuration.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of carriers within a frequency band for communicating with a base station via either carrier aggregation or dual connectivity. The UE may determine that a first parameter for communications over a first carrier exceeds a threshold with respect to corresponding parameters of other carriers, the first parameter being either a downlink reception parameter or an uplink transmission parameter. The UE may refrain from communicating over the first carrier based at least in part on the first parameter exceeding the threshold.

    Abstract: Methods, systems, and devices for wireless communications are described. In one example, a user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, and the UE may identify an open loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission. The identification of the open loop power control parameter may be based on the transmission being multicast to a plurality of UEs, and in some cases a UE may identify an open loop power control parameter that is different than an open loop power control parameter associated with feedback responsive to unicast transmissions. In various examples, open loop power control parameters may correspond to respective feedback resources (e.g., according to a configuration for a set of open loop power control parameters), or to respective physical resource indicators (e.g., as signaled in downlink control information).
