## Abstract

A method for measurement reporting performed by a wireless device includes obtaining a beam measurement configuration from a network. Based on the beam measurement configuration, the wireless device performs at least one beam measurement while operating in a dormant state. The wireless device reports a result of the at least one beam measurement to the network. The reporting is done after a transition from the dormant state to a connected state.

## Claims

### Claim at position 1

-39. (canceled)

### Claim 40

A method for measurement reporting performed by a wireless device, the method comprising:
receiving, from a network, a message indicating that the wireless device is to transition from a Radio Resource Control connected (RRC_CONNECTED) state to a Radio Resource Control Idle (RRC_IDLE) or Radio Resource Control Inactive (RRC_INACTIVE) state, the message comprising a beam measurement configuration;
based on the beam measurement configuration, performing the at least one beam measurement while operating in the RRC_IDLE or RRC_INACTIVE state;
transitioning from the RRC_IDLE or RRC_INACTIVE state to the RRC_CONNECTED state; and
reporting a result of the at least one beam measurement to the network while in the RRC_CONNECTED state.

### Claim 41 (depends on 40)

The method of claim 40, wherein the at least one beam measurement comprises at least one measurement performed on at least one reference signal that is beamformed by the network, the at least one reference signal comprising a Synchronization Signal Block (SSB).

### Claim 42 (depends on 40)

The method of claim 40, wherein the at least one beam measurement comprises at least one of:
Reference Signal Received Power, RSRP; and
Reference Signal Received Quality, RSRQ.

### Claim 43 (depends on 40)

The method of claim 40, wherein the result of the at least one beam measurement is reported in a RRCResumeComplete message.

### Claim 44 (depends on 40)

The method of claim 40, wherein the result of the at least one beam measurement is reported in a UEInformationResponse message.

### Claim 45 (depends on 40)

The method of claim 40, wherein the message comprises a RRCRelease message.

### Claim 46 (depends on 40)

The method of claim 40, wherein performing the at least one beam measurement while operating in the RRC_IDLE or RRC_INACTIVE state comprises performing the at least one beam measurement on a per cell and/or per carrier frequency while in the RRC_IDLE or RRC_INACTIVE state.

### Claim 47

A wireless device comprising:
processing circuitry configured to:
receive, from a network, a message indicating that the wireless device is to transition from a Radio Resource Control connected (RRC_CONNECTED) state to a Radio Resource Control Idle (RRC_IDLE) or Radio Resource Control Inactive (RRC_INACTIVE) state, the message comprising a beam measurement configuration;
based on the beam measurement configuration, perform the at least one beam measurement while operating in the RRC_IDLE or RRC_INACTIVE state;
transition from the RRC_IDLE or RRC_INACTIVE state to the RRC_CONNECTED state; and
report a result of the at least one beam measurement to the network while in the RRC_CONNECTED state.

### Claim 48 (depends on 47)
