    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor search spaces on a primary cell and an secondary cell in a carrier aggregation configuration. The UE may monitor the search spaces for control information according to a shared search space monitoring configuration. Based on the shared search space monitoring configuration, the UE may identify that the secondary cell is a scheduling cell and the primary cell is a scheduled cell (e.g., cross-carrier scheduling). The UE may monitor control channel candidates of search spaces on the primary cell and on the secondary cell for downlink control information messages scheduling data transmissions with the primary cell. In some examples, the cross-carrier scheduled communications may be configured according to a scheduling configuration, which may include one or more scheduling constraints.

    Abstract: Aspects relate to implementing a non-dropping rule for mini-slot based repetition of downlink channel data or control. In one example, cancelled repetition may be identified, non-cancelled remaining repetitions may be received, and acknowledgment feedback based on reception results may be generated. In another example, a plurality of time domain resource allocation (TDRA) candidate occasions may be identified where each occasion occurs within a different respective one of a plurality of mini-slots, each mini-slot carrying a different respective one of a plurality of downlink channel repetitions. A TDRA table may be maintained. The TDRA table may include TDRA entries such as location information of the plurality of TDRA candidate occasions associated with the plurality of downlink channel repetitions. The TDRA table may be maintained when at least one of the plurality of downlink channel repetitions is not decoded. A wireless communication device may refrain from dropping non-decoded downlink channel repetitions.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from a transmitter, an indication of a modulation signature associated with a reconfigurable intelligent surface (RIS). The receiver may receive a signal that uses the modulation signature, wherein the modulation signature identifies a link associated with the RIS and the transmitter. Numerous other aspects are described.

    Abstract: An aspect of this disclosure relates to a relay node, and a method of wireless communications by the relay node, including attempting to decode first code block groups of a transport block received in a resource allocation and according to a first encoding configuration. The aspects include identifying a symbol in the resource allocation that includes both of a first part of a successfully decoded one, and a first part of an unsuccessfully decoded one, of the plurality of first code block groups, and determining a modified transmit configuration for the symbol. Further, the aspects include encoding a second part of the successfully decoded one according to the first encoding configuration to define a second code block group that is outside of the symbol. Additionally, the aspects include transmitting the transport block including the one or more second code block groups and the symbol according to the modified transmit configuration.

    Abstract: Aspects of the present disclosure provide systems and methods for assigning one or more user equipments (UEs) at one or more corresponding starting positions of multiple slots to perform channel access procedures, such as listen before talk (LBT) procedures in New Radio unlicensed band (NR-U) sidelink communications. The network entity may indicate, to a UE, a starting position in a multi-opportunity grant (e.g., a DCI scheduling multiple slots). The network entity may multiplex different transmitter UEs with different starting positions. If the channel accessing procedure is successful, the transmitter UE with the earliest starting position than the rest may block the rest of the transmitter UEs. In some cases, starting position hopping may be used so that the multiple UEs may have different priority at different slots. In some cases, the DCI may include LBT parameters that are inherited from NR-U uplink transmission configurations.
