Switching between subband full duplex and half duplex modes for different periodicities

An apparatus for wireless communication at a network node, comprising:

• memory;
• and
• at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
• configure a time and frequency location for each of a first set of time and frequency resources in a subband (SB) full duplex (SBFD) operation associated with a SBFD mode and a second set of time and frequency resources associated with a half-duplex (HD) mode, wherein the first set of time and frequency resources includes a set of downlink (DL) and uplink (UL) SBs;
• and
• transmit, for a user equipment (UE), at least one of (1) a first indication of the time and frequency location for each DL or UL SB of the set of DL and UL SBs in the SBFD operation associated with the SBFD mode, or (2) a second indication of the second set of time and frequency resources associated with the HD mode.

A method of wireless communication at a user equipment (UE), comprising:

• operating in at least one of a downlink (DL) or uplink (UL) subband (SB) full duplex (SBFD) mode associated with a SBFD operation or a half-duplex (HD) mode, wherein the SBFD operation is associated with a first set of time and frequency resources and the HD mode is associated with a second set of time and frequency resources, wherein the first set of time and frequency resources includes a set of DL and UL SBs;
• obtaining at least one of (1) a first indication of a time and frequency location for each DL or UL SB of the set of DL and UL SBs in the SBFD operation associated with the SBFD mode, or (2) a second indication of the second set of time and frequency resources associated with the HD mode;
• and
• switching to operate in another of the SBFD mode or the HD mode based on at least one of the first indication or the second indication.
