Abstract
A DU and/or a CU of a distributed base station implement the techniques of this disclosure to support early data transmission from a UE operating in an inactive or idle state. In some embodiments, the DU receives (304) a MAC PDU from the UE when the radio connection between the UE and the DU is not active (302). The DU provides (308) the data packet included in the MAC PDU to the CU while preventing (306) the CU from initiating a procedure for resuming the radio connection. In this manner, the base station avoids an unnecessary transition of the UE to the connected state. The CU may then proceed with releasing (312) radio resources or otherwise determining to reactivate the radio connection.
Claims19
A method, in a central unit (CU) of a distributed base station, for managing data transmission from a user equipment (UE), the method comprising:
- receiving, from a distributed unit (DU), a transfer message including (i) an uplink message associated with a protocol for controlling radio resources and related to a UE, the uplink message including an early data transmission (EDT) indication, (ii) a radio configuration for the UE, and (iii) at least a portion of an uplink packet from the UE;
- and
- in response to the uplink message including the EDT indication, refraining from transmitting, to the UE, the radio configuration received from the DU.
A method, in a distributed unit (DU) of a distributed base station, for managing early data transmission (EDT) from a UE, the method comprising:
- receiving, when a radio resource control connection between the UE and the DU is not active, one or more messages from the UE;
- and
- transmitting, to a central unit (CU) of the distributed base station, a transfer message including (i) an uplink message associated with a protocol for controlling radio resources and related to a UE, the uplink message including an EDT indication, (ii) a radio configuration for the UE, and (iii) at least a portion of an uplink packet from the UE, while preventing, via the EDT indication, the CU from transmitting, to the UE, the radio configuration received from the DU.
A network node, operating as a central unit (CU) of a distributed base station, configured to manage data transmission from a user equipment (UE), the network node comprising:
- a transceiver;
- and
- processing hardware configured to:
- receive, from a distributed unit (DU), a transfer message including (i) an uplink message associated with a protocol for controlling radio resources and related to a UE, the uplink message including (ii) an early data transmission (EDT) indication, (ii) a radio configuration for the UE, and (iii) at least a portion of an uplink packet from the UE;
- and
- in response to the uplink message including the EDT indication, refraining from transmitting, to the UE, a radio configuration received from the DU.
