While BYUN teaches “receive, from a first distributed unit (DU) associated with the first CU of the wireless network prior to a request for admission of at least one resource, an indication of one or more types of resources for which the first DU supports admission during an energy saving mode of the first DU or an operation below a full capacity of the first DU ”,
BYUN does not expressively disclose:
wherein the one or more types of resources are associated with at least one capability of a user equipment (UE) to be served by the first DU,
wherein the at least one capability includes:
a beam correspondence associated with beam sweeping, and
whether the UE is capable of providing cross link interference (CLI) measurement and reporting,
transmit, ….., the request for the admission of the at least one resource that is selected by the CU based on having a type included in the one or more types of resources indicated by the first DU as supported for admission when the DU is in the energy saving mode or the operation below the full capacity.
PARK, in the same field of endeavor, discloses:
wherein the one or more types of resources are associated with at least one capability of a user equipment (UE) to be served by the first DU ( wireless device sends it’s capability information restriction information for network device/DU to network device/DU: “ capability restriction request may be sent by the wireless device (e.g., if allowed by a network) to signal the limited availability of some capabilities (e.g., due to hardware sharing, interference, and/or overheating) to the base station”: [0200]; aforesaid UE’s capability information includes serving information by DU : “ Inefficient radio resource configuration, increased call dropping, and/or increased link failures may occur, for example, if a base station DU configures radio resources of a cell without sufficient information, for example, from one or more wireless devices. Without sufficient information, the base station DU may configure non-preferred radio resource parameters and/or previously failed resource configuration parameters without wireless device information (e.g., resource preferences information and/or failure information of a wireless device).”: [0300]-[0301]; ),
wherein the at least one capability includes:
a beam correspondence associated with beam sweeping ( Part of capability of US, aforesaid wireless device provide beam sweeping after getting information from Base station : Aforesaid wireless device, are “similar or the same under” a configured criterion (==capability of UE ). In a multi-beam operation, a wireless device may perform an uplink beam sweeping to access a cell.”: [0245]-[0246]), and
whether the UE is capable of providing cross link interference (CLI) measurement and reporting (UE capability information include, inter alia, interference : ]0200]; “A wireless device may report its radio access capability information, which may be static. A base station may request one or more indications of capabilities for a wireless device to report based on band information (==cross talk interference information measurement and reporting ). A temporary capability restriction request may be sent by the wireless device (e.g., if allowed by a network) to signal the limited availability of some capabilities (e.g., due to hardware sharing, interference (NOTE: band information with interference which is crosstalk link measurement and report), and/or overheating) to the base station [0328]; NOTE: UE capability information include, inter alia, interference measurement and reporting to Base Station).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of BYUN to include the above recited limitations as taught by PARK. The suggestion/motivation would be to improve wireless communications without adversely increasing signaling overhead and/or decreasing spectral efficiency: (PARK; [0002]).
The combination for BYUN and PARK does not expressively disclose:
transmit, ….., the request for the admission of the at least one resource that is selected by the CU based on having a type included in the one or more types of resources indicated by the first DU as supported for admission when the DU is in the energy saving mode or the operation below the full capacity.

transmit, ….., the request for the admission of the at least one resource that is selected by the CU based on having a type included in the one or more types of resources indicated by the first DU as supported for admission when the DU is in the energy saving mode or the operation below the full capacity (see fig. 5 where CU 110 transmit “an admission request” the Donor DU 110-12 in Fig. 1 and Fig. 2: “ The Donor-CU 110-11 transmits (210) a first admission request to the Donor-DU 110-12. The first admission request comprises information about a resource set for the terminal device 130. For example, the resource set may be a DRB set, and/or a QoS flow set to be established for the terminal device 130. The first admission request also indicates the next downstream IAB node to reach the terminal device. The downstream IAB node may or may not be the serving IAB node for the terminal device 130. ”: [0059]; admission base on power saving of terminal : [0053]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of BYUN in view PARK to include the above recited limitations as taught by XU9629. The suggestion/motivation would be to improve admission control in an Integrated Access and Backhaul (IAB) system. (XU9629; [0001]).
