Aforesaid ”deactivation request (==an indication) may indicate that the gNB-DU 1 wants to enter into energy saving mode”: [0247]; aforesaid “deactivation request may include the list of cell(s) which the gNB-DU 1 manages. The deactivation request may be included in the information which represents service status of a cell which the gNB-DU 1 manages.”: [0249]; Aforesaid “F1 UE context is initiated by the gNB-CU and accepted or rejected by the gNB-DU based on admission control criteria (e.g., resource not available).”: [0161]; gNG CU receives deactivation request from gNB-DU to enter in saving energy mode : ]0112]-[0114]; “… gNB-CU receives deactivation request from gNB-DU1 indicating that gNB-DU1 wants to enter into energy saving mode:[00245]- [0247]); aforesaid gNB CU is not connected to any UE which below the capacity of gNB DU1 : no UE is connected to gNB DU1 : [0198]-[0199] ; “DU may transmit the deactivation request when there is no UE or IAB-node within coverage of the DU. For example, the DU may transmit the deactivation request when there is no data to be transmitted to and/or received from UEs or IAB-nodes connected to the DU. ”: [0206]; NOTE: gNB-DU1 is in full capacity but NO UE is connected to gNB DU1 now, so gNB-DU1 is not utilizing it full capacity so it is below its full capacity) ;
and
transmit, to the first DU (==gNB-DU1 1 in fig. 17) based on the indication… and while the first DU is operating under the energy saving mode or below the full capacity, a request for the admission of at least one resource in response to the at least one resource having a type included in the one or more types of resources indicated by the first DU (see fig. 17 element 1703, “when the gNB-CU accepts the deactivation request from the gNB-DU 1, the gNB-CU may transmit, to the gNB-DU 1, an existing message or a new message including the deactivation accept. The deactivation accept may indicate that the deactivation request from the gNB-DU 1 is permitted. ”: [0254]; aforesaid “gNB-DU 1 may enter into energy saving mode ”: [0257]-[0260]; “UE context is initiated by the gNB-CU and accepted or rejected by the gNB-DU based on admission control criteria (e.g., resource not available). ” : [0161]; “F1 UE context management function also supports the release of the context previously established in the gNB-DU.

The gNB-CU request the gNB-DU to release the UE Context when the UE enters RRC_IDLE or RRC_INACTIVE. ”: [0162]-[0170]).
While BYUN teaches “receive, from a first distributed unit (DU) associated with the first CU of the wireless network, 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, to the first DU based on … the handover request …., a request for the admission of at least one resource in response to the at least one resource having a type included in the one or more types of resources indicated by the first DU.
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:
receive, from a second CU of the wireless network, a handover request to handover the UE from a second DU to the first DU, wherein the second DU 1s associated with the second CU; and
transmit, to the first DU based … the handover request …., a request for the admission of at least one resource in response to the at least one resource having a type included in the one or more types of resources indicated by the first DU.
