Supporting allocation modification during transition instance in integrated access and backhaul network

An apparatus for wireless communication at a wireless device, comprising:

• memory;
• and
• one or more processors coupled to the memory and configured to cause the wireless device to:
• transmit or receive a set of rules to apply when a channel allocation is punctured due to overlapping of one or more resources, wherein the set of rules includes use of one or more of at least one modified resource allocation or a modified grant;
• determine a first channel allocation will be punctured based on an overlap of the first channel allocation with at least one of a guard symbol or a second channel allocation, wherein the first channel allocation is from a parent device of the wireless device to the wireless device and the second channel allocation is from the wireless device to a child device of the wireless device, or wherein the first channel allocation is from the wireless device to the child device of the wireless device and the second channel allocation is from the parent device of the wireless device to the wireless device;
• and
• use, for the first channel allocation, one or more of the at least one modified resource allocation or the modified grant for communication, in response to a determination that the first channel allocation will be punctured and based on the set of rules.

A non-transitory computer-readable storage medium storing computer executable code at a wireless device, the code when executed by one or more processors causes the wireless device to:

• transmit or receive a set of rules to apply when a channel allocation is punctured due to overlapping of one or more resources, wherein the set of rules includes use of one or more of one modified resource allocation or a modified grant;
• determine a first channel allocation will be punctured based on an overlap of the first channel allocation with at least one of a guard symbol or a second channel allocation, wherein the first channel allocation is from a parent device of the wireless device to the wireless device and the second channel allocation is from the wireless device to a child device of the wireless device, or wherein the first channel allocation is from the wireless device to the child device of the wireless device and the second channel allocation is from the parent device of the wireless device to the wireless device;
• and
• use, for the first channel allocation, one or more of the at least one modified resource allocation or the modified grant for communication, in response to a determination that the first channel allocation will be punctured and based on the set of rules.
