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: Aspects relate to dynamically changing the slot format of a slot between half-duplex and sub-band full-duplex and/or to changing flexible symbols within a flexible slot between half-duplex and sub-band full-duplex when a base station is configured to operate in a sub-band full-duplex mode. A slot format indicator (SFI) indicating the slot format of the slot may be signaled, for example, via downlink control information (DCI) mapped to a downlink control channel or medium access control (MAC) control element (MAC-CE) mapped to a downlink data channel. To improve reliability, various SFI boosting mechanisms may further be employed. For example, the base station may apply a higher aggregation level to the SFI, transmit repetitions of the SFI across multiple beams, apply a CRC enhancement and/or MCS enhancement to the downlink control channel carrying the SFI, and/or apply a power boost to the SFI.
