Abstract: The apparatus wireless communication may include a UE. The UE may receive a DL communication triggering a UL communication starting in a first UL slot/subframe from an NTN BS over at least one DL slot/subframe ending in a first DL slot/subframe. The UE may monitor for DL communications from the NTN BS in at least a subset of DL slots/subframes between the first DL slot/subframe and a second DL slot/subframe that is time-aligned with the first UL slot/subframe. The DL communication may trigger a second DL communication starting at a third DL slot/subframe and ending at a fourth DL slot/subframe, and the UL communication is based at least in part on receiving the second DL communication, and the UE may monitor the at least the subset of slots/subframes between the fourth DL slot/subframe and the second DL slot/subframe.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently allocating resources for multicast feedback from one or more user equipment (UEs) and efficiently retransmitting information in transport blocks to the one or more UEs. If a UE fails to decode one or more transport blocks of a set of transport blocks from a base station, the UE may report feedback, such as a negative acknowledgment (NACK), to the base station. The base station may receive the feedback from the UE and potentially from other UEs that failed to decode one or more transport blocks of the set of transport blocks, and the base station may multicast one or more outer-coded transport blocks to the UEs. Each of the outer-coded transport blocks may include a different combination (for example, a linear combination) of transport blocks of the set of transport blocks.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, where the UE may identify a closed loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission based on the multicast transmission transmitted to multiple UEs. The closed loop power control parameter may be indicated by a base station in a separate message than a downlink control information (DCI) scheduling the multicast transmission. For example, the base station may transmit the indication of the closed loop power control parameter in a group-transmit power control DCI or in a configuration for transmitting sounding reference signals. Additionally, the UE may adjust a transmit power for the acknowledgment feedback based on whether or not a DCI scheduling a retransmission is received in a time window after transmitting the acknowledgment feedback.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a group-common physical downlink shared channel (PDSCH), where the group-common PDSCH is repeated for a number of repetitions. Accordingly, the UE may determine this number of repetitions and then monitor for the group-common PDSCH based on the number of repetitions. In some implementations, the group-common PDSCH may include a semi-static repetition scheme, where the number of repetitions is indicated via a group aggregation factor. Additionally or alternatively, the group-common PDSCH may include a dynamic repetition scheme, where the number of repetitions is indicated via a group repetition number. Additionally, the techniques described herein may enable the configuration for the repeated group-common PDSCH to include gaps between each repetition of the group-common PDSCH and for the UE to transmit acknowledgment feedback for the repetitions of the group-common PDSCH.

Abstract: Quasi-colocation (QCL) indication is discussed after downlink transmission. In the management of multiple transmission-reception point (TRP) downlink transmissions, a second indication of a QCL assumption for a particular downlink transmission may be transmitted to receiving user equipment (UEs) after transmission of the downlink transmission. Once a TRP passes a listen before talk (LBT) procedure in a first time interval, it may send a first downlink control information (DCI) with indication of a first QCL assumption for the transmission in the first time interval. The TRP then transmits the downlink transmission intended for part of the multi-TRP downlink transmission. Upon receiving an indication that another of the TRPs was unsuccessful in its part of the multi-TRP transmission, the TRP may transmit a second DCI in a subsequent time interval with adjustments to the QCL assumption for the UEs to use in processing the downlink transmission from the first time interval.

Abstract: Methods, systems, and devices for wireless communications are described. A set of uplink control channel resources that are configured for acknowledgment transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of uplink control channel resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel. After failing to receive a multicast transmission, UEs may transmit an acknowledgment feedback message over one of the shared uplink control channel resources that is associated with the set of channel state information determined by the UE. A base station that receives the acknowledgment feedback message may transmit a multicast retransmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied uplink control channel resource.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive signaling indicating a set of multicast configurations for a set of multicast modes supported by the UE. Each multicast mode of the set of multicast modes may be associated with one or more radio resource control (RRC) states. The UE may determine a multicast configuration of the set of multicast configurations based on an RRC state according to which the UE is operating. The UE may receive, while operating according to the RRC state, multicast data according to the determined multicast configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an autonomous uplink (AUL) transmission to a base station using a configured resource set, the AUL transmission comprising reference signals and data signals. The UE may determine whether a response signal was received from the base station in response to the AUL transmission. The UE may determine whether the response signal indicates that the base station received the reference signals, or the reference signals and the data signals. The UE may select an uplink transmission scheme to use for subsequent transmissions to the base station, the selected uplink transmission scheme based at least in part on the determination of whether the response signal was received from the base station and whether the response signal indicates that the base station received the reference signals or the reference signals and the data signals.
