Abstract
A communication device for transmitting capabilities for mobility to a network supporting a standalone mode of a first radio access technology (RAT), comprises at least one storage device; and at least one processing circuit, coupled to the at least one storage device. The at least one storage device stores, and the at least one processing circuit is configured to execute instructions of: the communication device transmitting a first capability of the first RAT and a second capability of the first RAT to a first base station (BS) of a second RAT via the second RAT, wherein the first capability indicates a support of a standalone mode of the first RAT and the second capability indicates a plurality of supported bands of the first RAT.
Claims12
A communication device for transmitting capabilities for mobility to a network supporting a standalone mode of a first radio access technology (RAT), comprising:
- at least one storage device;
- and
- at least one processing circuit, coupled to the at least one storage device, wherein the at least one storage device stores, and the at least one processing circuit is configured to execute instructions of:
- transmitting a first capability of the first RAT and a second capability of the first RAT to a first base station (BS) of a second RAT via the second RAT, wherein the first capability indicates a support of a standalone mode of the first RAT and the second capability indicates a plurality of supported bands of the first RAT;
- and
- transmitting a third capability of the first RAT to the first BS of the second RAT, wherein the third capability indicates the communication device is capable of dual connectivity (DC) of the second RAT and the first RAT.
A first base station (BS) of a second radio access technology (RAT) for handling mobility to a second BS of a first RAT, comprising:
- at least one storage device;
- and
- at least one processing circuit, coupled to the at least one storage device, wherein the at least one storage device stores, and the at least one processing circuit is configured to execute instructions of:
- receiving a first capability of the first RAT and a second capability of the first RAT for a first communication device, wherein the first capability indicates a support of a standalone mode of the first RAT and the second capability indicates a plurality of supported bands of the first RAT;
- receiving a fourth capability and the second capability from the first communication device, the second BS or a CN, wherein the fourth capability indicates a support of mobility to New Radio (NR);
- handing over or redirecting the first communication device to the second BS of the first RAT, in response to the first capability or the fourth capability;
- and
- determining to initiate a secondary node (SN) addition procedure with a NR BS to configure EUTRA-NR dual connectivity (EN-DC) to the first communication device or the second communication device according to a third capability, wherein the third capability indicates a support of the EN-DC.
A communication device for transmitting capabilities for mobility to a New Radio (NR) standalone network, comprising:
- at least one storage device;
- and
- at least one processing circuit, coupled to the at least one storage device, wherein the at least one storage device stores, and the at least one processing circuit is configured to execute instructions of:
- transmitting a first capability and a second capability to a first base station (BS), wherein the first capability indicates a support of EUTRA-NR dual connectivity (EN-DC) and the second capability indicates a support of mobility to NR;
- and
- transmitting a third capability indicating a support of a NR standalone mode to the first BS;
- wherein the mobility to NR comprises a handover to a NR BS, camping on a NR cell and redirection to a NR cell.
