Abstract
An integrated access and backhaul (IAB) node may transition between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function. The IAB node may schedule communication using the DU function of the wireless device based on whether one or more guard symbols are provided for an allocation from a parent node for the MT function.
Claims20
A method of wireless communication at a wireless device, comprising:
- transitioning between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function;
- and
- scheduling a communication with a child node of the wireless device using the DU function of the wireless device based on whether or not one or more guard symbols are provided for an allocation from a parent node for the MT function, wherein:
- in response to the one or more guard symbols being provided for the allocation from the parent node and a number of the one or more guard symbols being equal to a number of requested guard symbols of the wireless device, the wireless device schedules the communication using the DU function without adjustment;
- and
- in response to the one or more guard symbols being provided for the allocation from the parent node and the number of the one or more guard symbols being less than the number of requested guard symbols of the wireless device, the wireless device schedules the communication using the DU function based on interference conditions.

An apparatus for wireless communication at a wireless device, comprising:
- means for transitioning between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function;
- and
- means for scheduling a communication with a child node of the wireless device using the DU function of the wireless device based on whether or not one or more guard symbols are provided for an allocation from a parent node for the MT function, wherein:
- in response to the one or more guard symbols being provided for the allocation from the parent node and a number of the one or more guard symbols being equal to a number of requested guard symbols of the wireless device, the means for scheduling schedules the communication using the DU function without adjustment;
- and
- in response to the one or more guard symbols being provided for the allocation from the parent node and the number of the one or more guard symbols being less than the number of requested guard symbols of the wireless device, the means for scheduling schedules the communication using the DU function based on interference conditions.
3 more elements
An apparatus for wireless communication at a wireless device, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- transition between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function;
- and
- schedule a communication with a child node of the wireless device using the DU function of the wireless device based on whether or not one or more guard symbols are provided for an allocation from a parent node for the MT function, wherein:
- in response to the one or more guard symbols being provided for the allocation from the parent node and a number of the one or more guard symbols being equal to a number of requested guard symbols of the wireless device, the at least one processor schedules the communication using the DU function without adjustment;
- and
- in response to the one or more guard symbols being provided for the allocation from the parent node and the number of the one or more guard symbols being less than the number of requested guard symbols of the wireless device, the at least one processor schedules the communication using the DU function based on interference conditions.
6 more elements
A non-transitory computer-readable medium storing computer executable code for wireless communication at a wireless device comprising a processor, the code being executable by the processor to:
- transition between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function;
- and
- schedule a communication with a child node of the wireless device using the DU function of the wireless device based on whether or not one or more guard symbols are provided for an allocation from a parent node for the MT function, wherein:
- in response to the one or more guard symbols being provided for the allocation from the parent node and a number of the one or more guard symbols being equal to a number of requested guard symbols of the wireless device, the wireless device schedules the communication using the DU function without adjustment;
- and
- in response to the one or more guard symbols being provided for the allocation from the parent node and the number of the one or more guard symbols being less than the number of requested guard symbols of the wireless device, the wireless device schedules the communication using the DU function based on interference conditions.
