Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration message which includes one or more parameters pertaining to blind decoding attempts by the UE of repetition-based physical downlink control channel (PDCCH) candidates. The UE may determine, from the configuration message, a blind decoding count mode which indicates a process for counting a number of blind decoding attempts of repetition-based PDCCH candidates. The UE may monitor for one or more repetitions of a downlink control information by attempting to blind decode the one or more repetitions of a PDCCH candidate in accordance with a maximum blind decode count and the blind decoding count mode.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, transmissions from a neighboring base station may interfere with downlink transmissions from a serving base station to a target user equipment (UE). To coordinate interference between the base stations (e.g., mitigate interference, stabilize interference, etc.), the serving base station may generate an interference coordination message and may transmit the message over-the-air (OTA) to one or more neighboring base stations. The message may include parameters indicating a coordination scheme for the neighboring base station(s) to use for modifying one or more scheduling decisions. The coordination scheme may be configured or dynamically selected and may include interfering beam fixation, interfering beam suppression, or interfering beam avoidance. A neighboring base station receiving the OTA interference coordination message may modify a scheduling decision to mitigate or stabilize interference when the serving base station is transmitting to the target UE.

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.

Abstract: Certain aspects of the present disclosure provide techniques for interference randomization for multiple transmission configuration indicator (multi-TCI) state communications with disjoint resource sets for certain systems, such a new radio (NR). A method for wireless communication by a user equipment (UE) is provided. The method generally includes determining a disjoint resource split of a set of resource blocks (RBs) for a multi-TCI state transmission, the determination based on a pseudo-random sequence. The UE decodes the multi-TCI state transmission based on the determination. A base station (BS) also determines the disjoint resource split based on the pseudo-random sequence and transmit the multi-TCI state transmission to a UE on a subset of the RBs based on the determination.

Abstract: Certain aspects of the present disclosure provide techniques for per transmission configuration channel sensing. A method for wireless communication by a user equipment (UE) generally includes monitoring a plurality of dummy physical downlink control channel (PDCCH) transmissions from at least one base station (BS). The dummy PDCCH transmissions use a different transmission configuration. The UE sends acknowledgment feedback for the plurality of dummy PDCCH transmission. The ACK feedback for the dummy PDCCH transmissions may be multiplexed with ACK feedback to the at least one BS for physical downlink shared channel (PDSCH) transmissions. A UE may receive a configuration reserving one or more bits in a UE codebook for providing the ACK feedback. Each reserved bit may be for control resource sets associated with a transmission configuration. The UE monitors PDDCH transmissions using different transmission configurations and uses the reserved bits to transmit ACK feedback for the PDCCH transmissions.

Abstract: Certain aspects of the present disclosure provide techniques for rate-matching for a transmission by multiple transmission configuration indicator (TCI) states, such as a multiple transmission reception point (multi-TRP) transmission. A method by a user equipment (UE) includes receiving one downlink control information (DCI) scheduling a downlink transmission associated with multiple transmission configuration indicator (TCI) states. The UE determines whether the downlink transmission is associated with one rate matching or is associated with a separate rate matching for each of the multiple TCI states. The UE derate matches the downlink transmission based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described that support group-based acknowledgment feedback techniques. Two or more different groups of downlink transmissions may each have an associated group-based acknowledgment feedback, and a base station may transmit downlink control information to a UE that indicates one or more parameters that are used to determine which downlink transmissions are to be reported in the group-based feedback. Based on the parameters in the downlink control information, the UE may determine the feedback to be reported, and a timing for when to transmit the feedback to the base station.
