Beam information in early measurements
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.
1. 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, the beam measurement configuration comprising a list of beams;
based on the beam measurement configuration comprising the list of beams, performing 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.
2. The method of claim 1 , 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).

6. The method of claim 1 , wherein the message comprises a RRCRelease message.
7. The method of claim 1 , 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.
8. 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, the beam measurement configuration comprising a list of beams;
based on the beam measurement configuration comprising the list of beams, perform 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.
9. The wireless device of claim 8 , 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).
10. The wireless device of claim 8 , wherein the at least one beam measurement comprises at least one of:
Reference Signal Received Power, RSRP; and
Reference Signal Received Quality, RSRQ.
11. The wireless device of claim 8 , wherein the result of the at least one beam measurement is reported in a RRCResumeComplete message or a UEInformationResponse message.
12. The wireless device of claim 8 , wherein the message comprises a RRCRelease message.
13. A method performed by a base station for configuring measurement reporting, the method comprising:
transmitting, to a wireless device, 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 configuring the wireless device to perform at least one beam measurement while the wireless device is operating in the RRC_IDLE or RRC_INACTIVE state, the beam measurement configuration comprising a list of beams;
receiving, from the wireless device, a reporting of a result of the at least one beam measurement, wherein the reporting is received after a first transition of the wireless device from the RRC_CONNECTED state to the RRC_IDLE or RRC_INACTIVE state and after a second transition of the wireless device from the RRC_IDLE or RRC_INACTIVE state to the RRC_CONNECTED state.
14. A base station comprising:
processing circuitry configured to:
transmit, to a wireless device, 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 configuring the wireless device to perform at least one beam measurement while the wireless device is operating in the RRC_IDLE or RRC_INACTIVE state, the beam measurement configuration comprising a list of beams;
receive, from the wireless device, a reporting of a result of the at least one beam measurement, wherein the reporting is received after a first transition of the wireless device from the RRC_CONNECTED state to the RRC_IDLE or RRC_INACTIVE state and after a second transition of the wireless device from the RRC_IDLE or RRC_INACTIVE state to the RRC_CONNECTED state.
