Abstract
A communication system is disclosed in which a base station apparatus obtains information identifying a total integrity protected uplink data rate for a user equipment (UE), allocates a portion of the total integrity protected uplink data rate to a secondary node (SN), and notifies the UE about the portion allocated to the SN.
Claims6
A method performed by a base station comprising a central unit (CU), and one or more distributed units (DUs) for handling a user-plane transmission for a user equipment (UE), the method comprising:
- obtaining, for a Data Radio Bearer (DRB), an integrity protected data rate for a Protocol Data Unit (PDU) session associated with the UE;
- and
- sending information identifying the integrity protected data rate, from the CU to at least one DU, when setting up or modifying a user context associated with the UE,
- wherein the information identifying the integrity protected data rate comprises an information element identifying a bit rate at a DRB level for a uplink integrity protected data transmission.
A method performed by a distributed unit (DU) of a distributed base station handling a user-plane transmission for a user equipment (UE), the method comprising:
- receiving, from a central unit (CU) when setting up or modifying a user context associated with the UE, information identifying an integrity protected data rate, for a Data Radio Bearer (DRB), for a Protocol Data Unit (PDU) session associated with the UE,
- wherein the information identifying the integrity protected data rate comprises an information element identifying a bit rate at a DRB level for a uplink integrity protected data transmission.
A base station comprising a central unit (CU), one or more distributed units (DUs) for handling a user-plane transmission for a user equipment (UE), the base station comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- obtain, for a Data Radio Bearer (DRB), an integrity protected data rate for a Protocol Data Unit (PDU) session associated with the UE;
- and
- send information identifying the integrity protected data rate, from the CU to at least one DU, when setting up or modifying a user context associated with the UE,
- wherein the information identifying the integrity protected data rate comprises an information element identifying a bit rate at a DRB level for a uplink integrity protected data transmission.
A distributed unit (DU) of a distributed base station handling a user-plane transmission for a user equipment (UE), the DU comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- receive, from a central unit (CU) when setting up or modifying a user context associated with the UE, information identifying an integrity protected data rate, for a Data Radio Bearer (DRB), for a Protocol Data Unit (PDU) session associated with the UE,
- wherein the information identifying the integrity protected data rate comprises an information element identifying a bit rate at a DRB level for a uplink integrity protected data transmission.
