Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may order assignment indicator values for transmissions for use by feedback information in a feedback message. The UE may receive, during a monitoring occasion, a first control information over a first serving cell and a second control information over a second serving cell, where each control information schedules a respective transmission for a scheduled serving cell. The UE may order assignment indicator values for the transmissions based on indexes associated with the first and second serving cells (e.g., scheduling serving cells), an index associated with the scheduled serving cell, a start time of the transmissions, or some combination thereof, among other examples. The assignment indicator values may be associated with hybrid automatic repeat request acknowledgement (HARQ/ACK) feedback, such that the UE may use the assignment indicator values to construct and transmit a feedback message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, via a first serving cell, a message including an indication to activate a second serving cell different from the first serving cell. The UE may receive, via the first serving cell, a control message indicating a first resource for transmitting a response message responsive to the message, and triggering a reference signal associated with time and frequency tracking for the second serving cell. The UE may transmit, via the first serving cell and within the first resource indicated via the control message, the response message acknowledging the message. The UE may then monitor a second resource of the second serving cell for the reference signal based on the control message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) to provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via cross component carrier. The UE may monitor control channel occasions, to receive wireless communications from a base station. For example, the UE may receive downlink control information (DCI) messages that may schedule multiple PDSCH over different component carriers. The DCI messages may include an indication of a timing offset for HARQ feedback for the multiple PDSCH. In some examples, the UE may be configured to receive multiple DCI messages and order the DCI messages based on component carrier indices or a PDCCH occasion, or both. The UE may then determine a slot to transmit HARQ feedback for the multiple PDSCH based on an indication in a latest DCI message identified according to the ordering.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a base station may transmit an indication of a pre-compensation timing value for transmission of a random access message by an aerial user equipment (UE), the random access message part of a random access procedure between the base station and the aerial UE when the aerial UE is in a connected state. The pre-compensation timing value may be based on a location of the aerial UE. In some examples, the base station may monitor a set of random access resources associated with the pre-compensation timing value and the aerial UE for the random access message, and the aerial UE may transmit the random access message using a first random access resource of a set of random access resources associated with the pre-compensation timing value and the aerial UE.

Abstract: Wireless communications systems and methods related to acknowledgement/negative-acknowledgement (ACK/NACK) feedback operations for multicast communications are provided. A first user equipment (UE) receives, from a base station (BS), a multicast feedback configuration indicating a first resource configuration for a negative-acknowledgement (NACK) feedback mode; and a second resource configuration for an acknowledgement/negative-acknowledgement (ACK/NACK) feedback mode. The first UE receives, from the BS, a first multicast communication. The first UE transmits, to the BS, a NACK feedback for the first multicast communication based on the first resource configuration. The first UE receives, from the BS, a second multicast communication. The first UE transmits, to the BS, an ACK feedback or a NACK feedback for the second multicast communication based on the second resource configuration.

Abstract: A configuration to enable a UE to select a new CSS set to use for monitoring for PDCCH based on changing conditions at the UE. The apparatus may receive, from a base station, a first indication of a search space for monitoring for a channel for at least one of system information, paging, or user data. A first set of monitoring occasions based on the search space indicated by the base station. The apparatus may determine a second set of monitoring occasions different than the first set of monitoring occasions based on a condition experienced by the apparatus. The apparatus may monitor for the channel based on the second set of monitoring occasions determined by the apparatus.

Abstract: A base station may transmit a multicast transmission to a group of user equipments (UEs) that are each configured with a group radio network temporary identifier (G-RNTI). The UEs may be configured to receive the transmission using the same modulation and coding scheme (MCS) and transport block size (TBS) such that the group of UEs may receive the same transmission. In particular, a UE may receive one or more configurations for multicast transmissions, each configuration associated with a G-RNTI. The UE may determine a MCS table for the G-RNTI. The UE may determine a TBS for a multicast transmission based on an overhead value for the G-RNTI. The UE may receive the multicast transmission based on the MCS table and the TBS.
