Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to transmission of a multicast message via a common frequency resource (CFR) in a full duplex slot. The CFR may be positioned within the downlink bandwidth parts (BWP)s configured for a group of user equipments (UE)s such that each UE in the group may monitor for and receive the multicast message. The network may indicate the frequency position of the CFR to the group of UEs. The frequency resources (e.g., the resource blocks) configured for downlink for a UE may be different between half duplex slots and full duplex slots. The network and the UE may determine the active CFR for a full duplex slot based on the resources configured for the full duplex slot. The UE may monitor for and receive a multicast transmission in the active CFR in the full duplex slot.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive, from a network entity, an indication of a set of time resource common to a set of UEs and available for communication of a multicast transmission from the network entity to two or more of the set of UEs, where the two or more of the set of UEs includes the UE, and where the set of time resources are a subset of a plurality of time resources of a carrier configured for the UE. The UE may receive, from the network entity, a grant for the multicast transmission and the multicast transmission over a subset of the set of resources, where the subset of the set of time resources is determined based on scheduling information associated with the grant and the indication of the set of time resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network may establish communications over a directional beam. The UE may receive, from the network, a configuration of one or more channel sounding messages for one or more directional beams, where each directional beam of the one or more directional beams is associated with a set of narrowband carriers, and each of the one or more channel sounding messages being configured for transmission on a narrowband carrier of the set of narrowband carriers. The UE may determine a trigger for transmitting the one or more channel sounding messaged based at least in part on the configuration and transmit, to the network, the one or more channel sounding messages on respective narrowband carriers in accordance with the trigger and the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may selectively determine to decode a downlink shared channel multicast transmission based on whether the downlink shared channel includes a retransmission of an initial multicast transmission. A base station may transmit a message in a downlink control channel to indicate if the downlink shared channel is carrying the retransmission of the initial multicast transmission. For example, the base station may transmit a group random network temporary identifier, downlink control information with a retransmission indicator bit, or both to indicate if the downlink shared channel is carrying the retransmission. In some cases, the message in the downlink control channel may be received at a layer one (L1) of the UE, and the downlink shared channel transmission may be decoded at L1 of the UE and sent to a layer two (L2) of the UE for processing.

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: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit a random access message (e.g., a message 3) associated with a random access procedure. A hybrid automatic repeat request (HARQ) feedback may be disabled for the random access procedure. The UE may initiate a contention resolution window associated with the random access procedure for a first downlink data channel transmission of a set of downlink data channel transmissions associated with the random access procedure. The UE may receive, during the contention resolution window, the first downlink data channel transmission carrying a contention resolution medium access control-control element (MAC-CE). The UE may transmit acknowledgment information for the first downlink data channel transmission carrying the contention resolution MAC-CE based on an indication to enable the HARQ feedback.

Abstract: The present disclosure relates to methods and devices for flexible resource allocation. In one aspect, a base station can generate a narrowband data channel including a plurality of resource blocks (RBs). The base station may shift a position of the RBs of the narrowband data channel to align with a wideband resource block group (RBG) boundary. The base station can also adjust a precoding resource block group (PRG) for the narrowband data channel. Also, the base station can transmit the narrowband data channel to a User Equipment (UE) based on adjusting the PRG. In another aspect, the base station may align a beginning or last RB of the plurality of RBs with the wideband RBG boundary and/or align a beginning or last RB of the PRG with the wideband RBG boundary. In another aspect, the base station may transmit an indication to the UE indicating a flexible resource allocation.

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.
