Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a search space associated with a physical downlink control channel (PDCCH) corresponding to a multicast/broadcast (MBS) physical downlink shared channel (PDSCH) for at least one MBS PDCCH communication having a payload that is scrambled according to a PDCCH payload scrambling sequence based on a value of a radio network temporary identifier (RNTI), wherein the value of the RNTI is equal to a group-RNTI (G-RNTI) or zero. The UE may receive the at least one MBS PDCCH communication. Numerous other aspects are described.

Abstract: A base station may transmit downlink control information messages (DCIs) that schedule multiple physical downlink shared channels (PDSCHs) in a single DCI (multi-PDSCH DCIs) to a UE. The base station may generate DCIs with multiple downlink association index (DAI) bitwidths. The base station generate a given DCI with a DAI bitwidth based on a DCI format of the DCI, based on whether the DCI is a multi-PDSCH DCI, based on a carrier that the DCI is transmitted on, or whether the base station is capable of scheduling the UE with multi-PDSCH DCIs in general. The UE may determine the DAI bitwidth of received DCIs and may determine whether any DCIs were missed based on the DAI and the bitwidth of the DAI.

Abstract: Methods, systems, and devices for wireless communications are described. A device may identify a transport block (TB) size for a TB that is scheduled across a set of component carriers (CCs) including a first CC and a second CC. The TB may include a first code block (CB) and a second CB. The device may rate match the TB with the set of CCs. Based on the rate matching, the device may identify redundancy portions of the first CB and redundancy portions of the second CB. The device may allocate a first redundancy portion of the first CB and a first redundancy portion of the second CB to the first CC, and may allocate a second redundancy portion of the first CB and a second redundancy portion of the second CB to the second CC. The device may transmit the TB over the set of CCs based on the allocating.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via multi-component carrier. The UE may monitor control channel occasions (e.g., physical downlink control channel (PDCCH) occasions), to receive wireless communications from a base station (e.g., a next-generation NodeBs (gNB)). For example, the UE may receive multiple downlink control information (DCI) messages that may schedule multiple PDSCH over different component carriers. The UE may identify one or multiple downlink assignment indices (DAI) in the received DCI messages. In some examples, the UE may generate one or more feedback bits of a HARQ feedback codebook (also referred to as an acknowledgement codebook). The one or more feedback bits include a same number of feedback bits for each downlink assignment index associated with each DCI message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a physical uplink control channel (PUCCH) format and a PUCCH resource to be used for concurrently transmitting hybrid automatic repeat request (HARQ) feedback and additional uplink control information based at least in part on downlink control information including a downlink assignment index equal to one. The UE may transmit one or more of the HARQ feedback or the additional uplink control information using the PUCCH format and the PUCCH resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a first network node (e.g., a user equipment (UE)) receiving first control information indicative of a first feedback scheme for multicast transmissions in a non-terrestrial network (NTN) and determining an applied feedback scheme based on the first feedback scheme. The method may also include the first network node monitoring for a multicast transmission and operating in accordance with the applied feedback scheme.

Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a network entity configuring a virtual cell group with multiple cells, where each cell may have a radio frequency spectrum band with a frequency gap that exceeds an operating band threshold. The network entity may transmit additional control signaling including information for the virtual cell group. In some cases, the additional control signaling may include resource allocation information for the virtual cell group, such that the UE may communicate multiple shared channels via different cells in the virtual cell group using the resources indicated in the resource allocation information. In some other cases, the additional control signaling may include a cancellation indication for the virtual cell group, such that the UE may refrain from communicating signals using one or more cells of the virtual cell group.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) messages scheduling downlink data transmissions at the UE, where at least one DCI message schedules two or more downlink data transmissions. The UE may determine, based on the DCI messages, a first set of downlink resources associated with a first control resource set (CORESET) group and a second set of downlink resources associated with a second CORESET group. The UE may receive one or more first downlink data transmissions on the first set of downlink resources and one or more second downlink data transmissions on the second set of downlink resources. The UE may communicate using a first set of parameters associated with the first CORESET group and a second set of parameters associated with the second CORESET group.
