Methods and apparatus for dynamic scheduling of sub-band full duplex communications

An apparatus for wireless communication by a user equipment, comprising:

• a memory;
• and
• a processor coupled with the memory and configured to:
• receive, at a user equipment (UE), a configuration message from a base station that modifies an initial sub-band full duplex (SBFD) resource configuration that is allocated for communication between the base station and the UE, wherein the initial SBFD resource configuration allows for both downlink and uplink communications on a sub-band basis within a same slot such that at least a first portion of bandwidth within a first slot is allocated for uplink communication and at least a second portion of the bandwidth within the first slot is allocated for downlink communication, wherein the configuration message is received as part of a downlink control information (DCI) that includes one or more bitfields that identify sub-bands within the first slot that are canceled or converted to one of uplink communications, downlink communications, or flexible sub-band communications;
• and
• communicate with the base station on a revised SBFD resource configuration based on the configuration message received from the base station, wherein the revised SBFD resource configuration modifies at least one of the first portion of the bandwidth within the first slot that was originally allocated for the uplink communication or the second portion of the bandwidth within the first slot that was originally allocated for the downlink communication in the initial SBFD resource configuration.

A non-transitory computer readable medium storing instructions, executable by a processor, for wireless communications, comprising instructions for:

• receiving, at a user equipment (UE), a configuration message from a base station that modifies an initial sub-band full duplex (SBFD) resource configuration that is allocated for communication between the base station and the UE, wherein the initial SBFD resource configuration allows for both downlink and uplink communications on a sub-band basis within a same slot such that at least a first portion of bandwidth within a first slot is allocated for uplink communication and at least a second portion of the bandwidth within the first slot is allocated for downlink communication, wherein the configuration message is received as part of a downlink control information (DCI) that includes one or more bitfields that identify sub-bands within the first slot that are canceled or converted to one of uplink communications, downlink communications, or flexible sub-band communications;
• and
• communicating with the base station on a revised SBFD resource configuration based on the configuration message received from the base station, wherein the revised SBFD resource configuration modifies at least one of the first portion of the bandwidth within the first slot that was originally allocated for the uplink communication or the second portion of the bandwidth within the first slot that was originally allocated for the downlink communication in the initial SBFD resource configuration.
