Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a maximum transmission power for an uplink transmission on a first cell of a first cell group (CG) based on a direction of communications (e.g., uplink, downlink, or flexible) with a separate cell of a second CG during a same duration of the uplink transmission and within a same first frequency range, where the direction of communications is either an actual direction or an assumed direction. The UE may receive an uplink grant scheduling the uplink transmission during a symbol and within the first frequency range, determine the maximum transmission power for the UE based on the direction of communications for the separate cell during the symbol and within the first frequency range, and subsequently transmit the uplink transmission in accordance with the maximum transmission power.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first rate matching resource indication that indicates that a first rate matching resource is available for use by the UE in reception of a downlink shared channel. The UE may also receive a second rate matching resource indication that indicates that a second rate matching resource is not available for use by the UE in reception of the downlink shared channel. The UE may identify a rate matching resource indication conflict arising from an overlap of at least one resource element included in both the first rate matching resource and the second rate matching resource. The UE may then resolve the rate matching resource indication conflict in accordance with a conflict resolution rule.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more retransmissions of an initial group-common transmission. The UE may receive, in accordance with a first SPS configuration, a group-common transmission of a group-common downlink shared channel, the group-common transmission being associated with a first RNTI. The UE may transmit feedback information for the group-common transmission. The UE may then receive a downlink control information (DCI) message scheduling either a group-common retransmission of the group-common downlink shared channel or a unicast retransmission of the group-common downlink shared channel. The DCI may indicate that either the group-common retransmission is associated with the first RNTI or that the unicast retransmission is associated with a second RNTI that may be different from the first RNTI.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink control information (DCI) message to one or more user equipments (UEs) scheduling a multicast data message in a multicast downlink shared channel, the DCI message indicating a feedback process identifier (ID) for the multicast data message. The base station may transmit an additional DCI message to a UE scheduling a retransmission of the multicast data message in a unicast downlink shared channel and indicating a feedback process ID for the retransmission of the multicast data message. The feedback process ID for the retransmission may be the same as, or different from, the initial transmission of the multicast data message. The UE may transmit feedback for the multicast data message based on receiving the initial transmission of the multicast data or the retransmission of the multicast data and the feedback process IDs.

Abstract: Methods, systems, and devices for wireless communications are described, that provide for configuration and switching between multiple groups of search space sets based on activated serving cells or activated resources for one or more serving cells. An access network entity may configure multiple groups of search space sets, and a user equipment (UE) may monitor for control information in an activated search space set group. A first group of search space sets may be activated based on a serving cell being activated, and the UE may switch to a second group of search space sets when the serving cell is deactivated. Search space set group switching also may be performed based on one or more activated bandwidth parts (BWPs). An access network entity may trigger search space set group switching using explicit signaling, based on cell activation/deactivation, based on a timer, or any combinations thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration for periodic communications. The UE may determine that the UE has successfully received a respective initial transmission in each transmission cycle of a threshold number of transmission cycles associated with the periodic communications. The UE may deactivate repetitions in one or more transmission cycles based at least in part on the determination. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a wireless device with dual subscriptions to prioritize a subscriber. A user equipment (UE) may configure a first channel for a first subscription and a second channel for a second subscription. The UE may determine one or more slots for the first subscription for communicating in a first direction and for the second subscription for communicating in a second direction, where the first and second directions are different. The UE may prioritize communications of the first subscription according to the determined slots. The prioritizing may be based on the direction, whether the communications are scheduled or configured, or whether the slot includes a monitoring occasion. The UE may communicate in the first direction according to the first subscription.

Abstract: Methods, systems, and devices for wireless communications are described. In some implementations, a method for wireless communication at a user equipment (UE) is described that includes identifying that the UE is in carrier aggregation communication with a primary and secondary cell. The method may also include monitoring, during one or more time intervals, UE-specific search spaces of the secondary cell for control information scheduling data communications on the primary cell. The method may include switching, during one or more different time intervals, to monitoring UE-specific search spaces of the primary cell. Another method describes wireless communication at a base station that may configure a UE to communicate via carrier aggregation, transmit control information via the secondary cell to the UE during downlink TTIs, and transmit control information via the primary cell to the UE during uplink TTIs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may connect with a base station over a set of component carriers according to a carrier aggregation configuration. The UE may then monitor a search space configured for scheduling multiple component carriers and may receive downlink control information (DCI) based on monitoring the search space. The DCI may include a carrier indicator field (CIF) and may schedule a set of data transmissions over two or more component carriers (e.g., from the set of component carriers). The UE may determine that the two or more component carriers include the first component carrier and the second component carrier based on the monitored search space, the CIF within the DCI, or both. The UE may then transmit and receive the set of data transmissions over the first and second component carriers.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station over a set of component carriers according to a carrier aggregation configuration. In some cases, the UE may receive an indication of one or more groups of units, where each group may include one or more component carriers and/or one or more time intervals of each component carrier. The UE may receive downlink control information (DCI) including one or more fields that are common to a group of units that may schedule a set of data transmissions over the one or more groups of units such that the single DCI may schedule multiple component carriers (e.g., two or more) over one or more time intervals. The UE may transmit or receive the set of data transmissions (e.g., uplink or downlink data transmissions) over the scheduled units based on receiving the DCI.
