## Abstract

The present document describes methods, systems, and devices for configuring a measurement object in a wireless communication network. A plurality of candidate serving cell measurement object (MO) identifiers (IDs) are provided from a centralized unit (CU) to a distributed unit (DU). A a serving cell MO is selected by the DU from the plurality of candidate serving cell MO IDs to be used for a user equipment (UE). A per-bandwidth part (BWP) serving cell MO configuration is configured by the DU according to the serving cell MO.

## Claims

### Claim 1

A method for measurement configuration in a wireless communication network, comprising:
receiving, by a distributed unit (DU), a list of candidate serving cell measurement object (MO) identifiers (IDs) from a centralized unit (CU);
selecting, by the DU, a serving cell MO from the list of candidate serving cell MO IDs to be used for a user equipment (UE); and
configuring, by the DU, a serving cell MO configuration for a bandwidth part (BWP) according to the serving cell MO.

### Claim 2 (depends on 1)

The method of claim 1, wherein
the list of candidate serving cell MO IDs are provided in a UE context setup request message or a UE context modification request message sent from the CU to the DU.

### Claim 3 (depends on 2)

The method of claim 2, further comprising:
transmitting, by the DU, a response message to the UE context setup request message or the UE context modification request message, wherein the response message comprises information indicating:
which serving cell MO based on a non-cell defining synchronization signal block (NCD-SSB) is configured for a BWP configured for the UE.

### Claim 4 (depends on 3)

The method of claim 3, wherein
the response message comprises the serving cell MO configuration for the BWP, wherein
the serving cell MO configuration for the BWP is comprised in a serving cell MO information element (IE), the serving cell MO IE is comprised in a servingCellConfig IE.

### Claim 5 (depends on 1)

The method of claim 1, wherein
one or more candidate serving cell MO IDs are based on a non-cell-defining synchronization signal block (NCD-SSB) indicated by the CU to the DU.

### Claim 6 (depends on 5)

The method of claim 5, wherein
the one or more candidate serving cell MO IDs are indicated by the CU to the DU with:
a frequency information of the NCD-SSB that is associated with the serving cell MO.

### Claim 7 (depends on 1)

The method of claim 1, further comprising:
configuring, by the DU, a downlink BWP.

### Claim 8 (depends on 7)

The method of claim 7, wherein
the downlink BWP includes an NCD-SSB; and the method further comprises:
configuring, by the DU, the serving cell MO configuration for the BWP based on the NCD-SSB.

### Claim 9

A method for measurement configuration in a wireless communication network, comprising:
transmitting, by a centralized unit (CU) to a distributed unit (DU), a list of candidate serving cell measurement object (MO) identifiers (IDs); and
receiving, by the CU from the DU, information indicating which serving cell MO is configured for a bandwidth part (BWP) configured for a UE, and the information is based on a list of candidate serving cell MO IDs.

### Claim 10 (depends on 9)

The method of claim 9, wherein the list of candidate serving cell MO IDs are transmitted in a UE context setup request message or a UE context modification request message from the CU to the DU.

### Claim 11 (depends on 9)

The method of claim 9, wherein the information indicating the configured serving cell MO comprises a serving cell MO configuration for a BWP, and
the serving cell MO configuration for the BWP is transmitted in a UE context setup response message or a UE context modification response message from the DU to the CU.

### Claim 12 (depends on 9)

The method of claim 9, wherein
one or more candidate serving cell MO IDs are based on a non-cell-defining synchronization signal block (NCD-SSB) indicated by the CU.

### Claim 13 (depends on 9)

The method of claim 9, wherein the configured serving cell MO is related with:
a frequency information of the NCD-SSB that is associated with the serving cell MO.

### Claim 14 (depends on 9)

The method of claim 9, further comprising:
configuring, by the CU, a serving cell MO configuration for the UE based on the serving cell MO configuration for the BWP; or
transmitting, by the CU, a dedicated RRC message to the UE including the serving cell MO configuration.

### Claim 15 (depends on 1)

A device for wireless communication comprising:
at least one processor; and
a memory in communication with the at least one processor, the memory storing a plurality of instructions executable by the at least one processor to cause the device to:
implement the method of claim 1.

### Claim 16 (depends on 9)

A device for wireless communication comprising:
at least one processor; and
a memory in communication with the at least one processor, the memory storing a plurality of instructions executable by the at least one processor to cause the device to:
implement the method of claim 9.
