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 be configured with a mapping between downlink control information (DCI) codepoint values, multicast configurations, and unicast configurations. A DCI may then signal to the UE to apply one of a multicast configuration or a unicast configuration to receive a shared data channel transmission. For example, for a given DCI field of a group-common downlink control channel for multicast data, one or some DCI codepoint values may be associated with values configured for a multicast configuration, while remaining codepoints are associated with values configured for a unicast configuration. In some implementations, the UE may identify which multicast configuration or unicast configuration to apply based on the mapping, a type of data transmission scheduled by the DCI, specified values for the DCI codepoint values, whether the shared data channel transmission is a retransmission, or a combination thereof.

Abstract: In methods, systems, and devices for wireless communications, 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: In embodiments of systems and methods for managing control signaling for multicast communications, a base station may transmit to a wireless device an indication of whether to monitor a group common physical downlink control channel (GC PDCCH), a wireless device-specific PDCCH for multicast configuration information, or both. The base station may determine a schedule for transmitting multicast communications to the wireless device based on a capability reported by the wireless device, and may transmit to the wireless device an indication of whether a transport block for GC multicast communications including services for multicast communications will be scheduled by the GC PDCCH, the wireless device-specific PDCCH, or both. The base station may transmit, and the wireless device may receive, the multicast communications according to the multicast configuration information and the schedule.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for an orthogonal frequency division (OFDM) symbol that includes one or more cell-specific reference signal (CRS) resource elements and one or more narrowband physical downlink shared channel (NPDSCH) resource elements, an NPDSCH energy per resource element (EPRE), wherein the NPDSCH EPRE for the OFDM symbol is based at least in part on an EPRE differential between a narrowband reference signal (NRS) EPRE and a CRS EPRE. The UE may demodulate the OFDM symbol based at least in part on the NPDSCH EPRE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a set of measurements related to a unicast service channel based at least in part on one or more reference signals associated with the unicast service channel and a set of measurements related to a multicast/broadcast service (MBS) channel based at least in part on one or more reference signals associated with the MBS channel. The UE may apply one or more communication parameters to ensure continuity for an MBS service. For example, in some aspects, the one or more communication parameters are based at least in part on the set of measurements related to the unicast service channel and the set of measurements related to the MBS channel. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure an outer coded block which a user equipment (UE) may implement to recover an unsuccessfully decoded transmission. The base station may send, to the UE, downlink control information (DCI) indicating an outer coding scheme for the group of data blocks (e.g., a first data block and a second data block). The UE may monitor for the data blocks and the outer coded block. The UE may decode the data blocks based on the outer coded block and the outer coding scheme. In some examples, the outer code block may be made up of a combination of the first and second data blocks. The UE may use the combination of the outer coded block and one of the data blocks to decode an unsuccessfully decode data block.
