Abstract
Certain aspects of the present disclosure provide a method for bearer count alignment during handover of a user equipment (UE) from a first radio access technology (RAT) to a second RAT. The UE establishes radio resource control (RRC) connections with the second RAT and transmits data radio bearer (DRB) capability of the UE to the second network. The second network utilizes this information to set up the DRBs with the UE.
Claims42
A method for wireless communications by a user equipment (UE), comprising:
- receiving a message from a first network to handover to a second network;
- establishing radio resource control (RRC) connections with the second network;
- and
- transmitting data radio bearer (DRB) capability of the UE to the second network, wherein the DRB capability includes a number of DRBs that are supported by the UE.
A method for wireless communications by a first network, comprising:
- receiving a notification of a handover of a user equipment (UE) and the context associated with the UE from a second network, wherein the first network is different from the second network;
- establishing radio resource control (RRC) connection with the UE;
- receiving data radio bearer (DRB) capability of the UE;
- and
- setting up DRBs with the UE based on the received UE context, wherein the number of the DRBs is equal to the DRB capability of the UE.
An apparatus for wireless communications by a user equipment (UE), comprising:
- logic for receiving a message from a first network to handover to a second network;
- logic for establishing radio resource control (RRC) connections with the second network;
- and
- logic for transmitting data radio bearer (DRB) capability of the UE to the second network, wherein the DRB capability includes a number of DRBs that are supported by the UE.
An apparatus for wireless communications by a first network, comprising:
- logic for receiving a notification of a handover of a user equipment (UE) and the context associated with the UE from a second network, wherein the first network is different from the second network;
- logic for establishing radio resource control (RRC) connection with the UE;
- logic for receiving data radio bearer (DRB) capability of the UE;
- and
- logic for setting up DRBs with the UE based on the received UE context, wherein the number of the DRBs is equal to the DRB capability of the UE.
An apparatus for wireless communications by a user equipment (UE), comprising:
- means for receiving a message from a first network to handover to a second network;
- means for establishing radio resource control (RRC) connections with the second network;
- and
- means for transmitting data radio bearer (DRB) capability of the UE to the second network, wherein the DRB capability includes a number of DRBs that are supported by the UE.
An apparatus for wireless communications by a first network, comprising:
- means for receiving a notification of a handover of a user equipment (UE) and the context associated with the UE from a second network, wherein the first network is different from the second network;
- means for establishing radio resource control (RRC) connection with the UE;
- means for receiving data radio bearer (DRB) capability of the UE;
- and
- means for setting up DRBs with the UE based on the received UE context, wherein the number of the DRBs is equal to the DRB capability of the UE.
A computer-program product for wireless communications by a user equipment (UE), comprising a computer readable medium having instructions stored thereon, the instructions being executable by one or more processors and the instructions comprising:
- instructions for receiving a message from a first network to handover to a second network;
- instructions for establishing radio resource control (RRC) connections with the second network;
- and
- instructions for transmitting data radio bearer (DRB) capability of the UE to the second network, wherein the DRB capability includes a number of DRBs that are supported by the UE.
A computer-program product for wireless communications by a first network, comprising a computer readable medium having instructions stored thereon, the instructions being executable by one or more processors and the instructions comprising:

- instructions for establishing radio resource control (RRC) connection with the UE;
- instructions for receiving data radio bearer (DRB) capability of the UE;
- and
- instructions for setting up DRBs with the UE based on the received UE context, wherein the number of the DRBs is equal to the DRB capability of the UE.
An apparatus for wireless communications by a user equipment (UE), comprising at least one processor configured to:
- receive a message from a first network to handover to a second network;
- establish radio resource control (RRC) connections with the second network;
- and
- transmit data radio bearer (DRB) capability of the UE to the second network, wherein the DRB capability includes a number of DRBs that are supported by the UE.
