Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a transmission type for a physical downlink shared channel, wherein the transmission type is a multicast transmission type or a unicast transmission type. The UE may determine, based at least in part on the transmission type for the physical downlink shared channel, a transmission configuration indicator state, of a plurality of possible transmission configuration indicator states, that corresponds to a quasi-co-location assumption, of a plurality of possible quasi-co-location assumptions, for the physical downlink shared channel. The UE may decode the physical downlink shared channel based at least in part on the transmission configuration indicator state. Numerous other aspects are provided.

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: Various aspects described herein relate to techniques for frequency hopping for a wideband allocation in wireless communications. A wideband allocation of resources for transmitting uplink wireless communications can be determined, as well as a frequency hopping offset related to one or more narrowbands for transmitting uplink wireless communications. In addition, it can be determined whether to apply the frequency hopping offset to the wideband allocation in communicating data. The data can be communicated over resources related to the wideband allocation with the frequency hopping offset applied communicating, based on determining to apply the frequency hopping offset.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) block including DCI for a set of transport blocks scheduled for the UE, the DCI including a set of fields. The UE may decode the DCI block to obtain the DCI for the set of transport blocks, where at least two fields of the downlink control information are jointly decoded according to an encoding scheme, and where each possible output of the encoding scheme corresponds to a jointly valid combination of the at least two fields. The UE may receive the set of transport blocks from a base station based on the DCI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a satellite of a non-terrestrial network (NTN) may establish communications on a beam of the satellite. The UE may receive, on a first carrier of a first set of carriers associated with a first beam, a configuration for the first set of carriers associated with the first beam and a second set of carriers associated with a second beam. The first carrier may be used to send a first set of synchronization signals, and a second carrier of the second set of carriers may be used to send a second set of synchronization signals. The UE may identify some system information associated with the second set of carriers based on the configuration and reselect to the second beam based on the configuration.

Abstract: Methods, systems, and devices for wireless communications are described that support multiplexing multicast and unicast feedback. A base station may provision different subsets of resources from a set of resources for multicast feedback message transmission based on channel metric(s) of a user equipment (UE). The set of resources may include a plurality of subsets of resources, with each subset of resources being associated with a corresponding channel metric or range of channel metrics associated with each UE receiving the multicast transmission. A UE may determine that a feedback indication is to be provided in response to the multicast transmission, and select a subset of resources from the plurality of subsets of resources based on its own channel metric. The UE may multiplex the multicast feedback, an indication of the selected subset, and unicast feedback in a multiplexed feedback transmission to the base station.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for establishing rules for scheduling downlink data transmissions and flow control feedback for the downlink data transmissions to avoid confusion at a base station and a user equipment (UE). In one example, when flow control feedback from a UE is disabled for a downlink data transmission, the UE may still operate according to a timing for reporting flow control feedback for the downlink data transmission. In this example, the UE may drop (e.g., refrain from decoding) other downlink data transmissions based on the timing for reporting flow control feedback. In another example, when flow control feedback from a UE is disabled for a downlink data transmission, other downlink data transmissions to the UE may be scheduled according to one or more rules to avoid confusion.

Abstract: Methods, systems, and devices for multicast wireless communications are described. A base station may configure a user equipment (UE) for providing feedback for multicast transmissions from the base station while the UE is in an inactive or idle mode. Based on a configuration sent to the UE from the base station, the UE may determine resources or a timing advance (TA) to use for transmission of a feedback message for multicast communications. A base station may configure a UE with multiple TA commands, each corresponding to a TA value and a set of channel metrics associated with group of cells including a serving cell of the UE. Based on measure channel metrics at the UE, the UE may determine a TA to use for multicast feedback. TA values may be determined using neural network modeling.

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.
