Hybrid in-band same frequency full-duplex and offset-frequency full-duplex wireless communication

A method performed by a network entity, the method comprising:

• transmitting, to a user equipment (UE), a first allocation indicating a carrier bandwidth;
• responsive to a first pathloss between the network entity and the UE satisfying a threshold for a same-frequency full-duplex (SFFD) operation, simultaneously transmitting first data to the UE over a first frequency band and receiving second data from the UE over the first frequency band based on the first allocation indicating the carrier bandwidth, wherein the first frequency band is within the carrier bandwidth;
• transmitting, to the UE based on a second pathloss between the network entity and the UE failing to satisfy the threshold, a second allocation indicating a second frequency band for downlink (DL) communications and a third frequency band for uplink (UL) communications, wherein the second allocation is based on the first allocation such that the second frequency band and third frequency band are within the carrier bandwidth of the first allocation;
• switching, based on the second allocation, to an offset-frequency full-duplex (FD) operation;
• transmitting, based on the offset-frequency FD operation and the second allocation, third data to the UE over the second frequency band;
• and
• receiving, simultaneously with transmitting the third data and based on the offset-frequency FD operation and the second allocation, fourth data from the UE over the third frequency band, wherein the third frequency band is distinct from the second frequency band wherein the second frequency band and the third frequency band are spaced apart by at least one of a fourth frequency band or a fifth frequency band, and wherein the fourth frequency band and the fifth frequency band are allocated to a second UE for the offset-frequency FD operation based on a third pathloss between the network entity and the second UE failing to satisfy the threshold.

• receive, from the network entity based on a second pathloss between the UE and the network entity failing to satisfy the threshold, a second allocation indicating a second frequency band for uplink (UL) communications and a third frequency band for downlink (DL) communications, wherein the second allocation is based on the first allocation such that the second frequency band and the third frequency band are within the carrier bandwidth of the first allocation;
• switch, based on the second allocation, to an offset-frequency full-duplex (FD) operation;
• transmit, based on the offset-frequency FD operation and the second allocation, third data to the network entity over the second frequency band;
• and
• receive, simultaneously with transmitting the third data and based on the offset-frequency FD operation and the second allocation, fourth data from the network entity over the third frequency band, wherein the third frequency band is distinct from the second frequency band, wherein the second frequency band and the third frequency band are spaced apart by at least one of a fourth frequency band or a fifth frequency band, and wherein the fourth frequency band and the fifth frequency band are allocated to a second UE for the offset-frequency FD operation based on a third pathloss between the network entity and the second UE failing to satisfy the threshold.
