Abstract
To configure a UE, a DU of a distributed base station receives, from a central unit (CU) of the distributed base station, a UE context request message including a conditional indication related to a conditional procedure (2202); generates, and in response to the conditional indication, configuration information related to the conditional procedure (2220); and transmits, to the CU, a UE context response message including the configuration information (2216).
Claims16
A method in a distributed unit, DU, of a distributed base station, for configuring a user equipment (UE), the method comprising:
- receiving, from a central unit, CU, of the distributed base station, a UE context request message;
- in a first instance, determining that the UE context request message includes a conditional indication related to a conditional procedure and generating, based on the conditional indication, configuration information related to the conditional procedure, including generating a cell group configuration with a reconfiguration with sync information element (IE) or field;
- in a second instance, determining that the UE context request message does not include a conditional indication related to a conditional procedure and determining that the UE context request message includes a handover preparation information, generating, based on the handover preparation information, configuration information related to an immediate procedure, including generating a cell group configuration with a reconfiguration with sync IE or field;
- and
- transmitting, to the CU, a UE context response message including the configuration information.
A method in a central unit (CU) of a distributed base station, for configuring a user equipment, UE, the method comprising:
- transmitting, to a distributed unit (DU) of the distributed base station, a UE context request message;
- in a first instance, including, in the UE context request message, a conditional indication related to a conditional procedure and receiving, based on the transmitting, a UE context response message including configuration information related to the conditional procedure, the configuration information including a cell group configuration with a reconfiguration with sync information element (IE) or field;
- and
- in a second instance, omitting from the UE context request message, a conditional indication related to a conditional procedure and including, in the UE context request message, a handover preparation information and receiving, based on the transmitting, a UE context response message including configuration information related to an immediate procedure with a reconfiguration with sync IE or field.
A distributed unit (DU) of a base station, the DU including processing hardware and configured to:
- receive, from a central unit (CU) of the distributed base station, a UE context request message;
- in a first instance, determine that the UE context request message includes a conditional indication related to a conditional procedure, generate, based on the conditional indication, configuration information related to the conditional procedure, including a cell group configuration with a reconfiguration with sync information element (IE) or field;
- in a first instance, determine that the UE context request message does not include a conditional indication related to a conditional procedure and if the UE context request message includes a handover preparation information, generate, based on the handover preparation information, configuration information related to an immediate procedure including generate a cell group configuration with a reconfiguration with sync IE or field;
- and
- transmit, to the CU, a UE context response message including the configuration information.
