Devices, apparatuses, and computer readable media for resource assignment

An apparatus for a network device, comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the network device at least to:
• transmitting to a terminal device served by the network device, a configuration of sub-band full duplex comprising non-contiguous downlink sub-bands, a configuration of a non-sub-band full duplex comprising a contiguous downlink band, and a frequency domain resource assignment for downlink;
• determine whether the frequency domain resource assignment is for the sub-band full duplex or for the non-sub-band full duplex;
• if the frequency domain resource assignment is for the sub-band full duplex, apply as a reference point of physical resource blocks for the frequency domain resource assignment, a first physical resource block of a first downlink sub-band of the non-contiguous downlink sub-bands;
• else if the frequency domain resource assignment is for the non-sub-band full duplex, apply as a reference point of physical resource blocks for the frequency domain resource assignment, a second physical resource block of the contiguous downlink band that is different from the first physical resource block;
• and
• determine physical resource blocks of the frequency domain resource assignment by using the applied reference point and transmit data in the determined physical resource blocks.

A method performed by an apparatus for a terminal device, comprising:

• receiving from a network device serving the terminal device, a configuration of sub-band full duplex comprising non-contiguous downlink sub-bands, a configuration of a non-sub-band full duplex comprising a contiguous downlink band, and a frequency domain resource assignment for downlink;
• determining whether the frequency domain resource assignment is for the sub-band full duplex or for the non-sub-band full duplex;
• if the frequency domain resource assignment is for the sub-band full duplex, applying as a reference point of physical resource blocks for the frequency domain resource assignment, a first physical resource block of a first downlink sub-band of the non-contiguous downlink sub-bands;
• else if the frequency domain resource assignment is for the non-sub-band full duplex, applying as a reference point of physical resource blocks for the frequency domain resource assignment, a second physical resource block of the contiguous downlink band that is different from the first physical resource block;
• and
• determining physical resource blocks of the frequency domain resource assignment by using the applied reference point and receiving data in the determined physical resource blocks.
