Methods and apparatus for user equipment capability exchange

A wireless communication apparatus, comprising:

• means for transmitting, by a base station, one or more enquiries for user equipment (UE) capabilities associated with one or more of:
• one or more bands that are used by a network, a maximum number of carriers or bandwidth advertised by the network on uplink or downlink, or support of understanding skipped fall back band combinations by the network;
• means for receiving, by the base station, the associated UE capabilities and an identifier that identifies a portion of UE capabilities for features and band combinations supported by the UE for a mode of operation of multiple modes of operation of the UE;
• and
• means for determining, by the base station by accessing a capability database that maps identifiers to UE capabilities for features and band combination supported by one or more UEs, the portion of UE capabilities for features and band combinations supported by the UE based on the received identifier.

A wireless communication apparatus, comprising:

• at least one computer processor;
• and
• a memory coupled to the at least one computer processor, wherein the at least one computer processor is adapted to:
• transmit, by a base station, one or more enquiries for user equipment (UE) capabilities associated with one or more of:
• one or more bands that are used by a network, a maximum number of carriers or bandwidth advertised by the network on uplink or downlink, or support of understanding skipped fall back band combinations by the network;
• receive, by the base station, the associated UE capabilities and an identifier that identifies a portion of UE capabilities for features and band combinations supported by the UE for a mode of operation of multiple modes of operation of the UE;
• and
• access, by the base station, a capability database to determine, based on the identifier, the portion of UE capabilities for features and band combinations supported by the UE.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• program code executable by a computer for causing the computer to transmit, by a base station, one or more enquiries for user equipment (UE) capabilities associated with one or more of:
• one or more bands that are used by a network, a maximum number of carriers or bandwidth advertised by the network on uplink or downlink, or support of understanding skipped fall back band combinations by the network;
• program code executable by the computer for causing the computer to receive, by the base station, the associated UE capabilities and an identifier that identifies a portion of UE capabilities for features and band combinations supported by the UE for a mode of operation of multiple modes of operation of the UE;
• and
• program code executable by the computer for causing the computer to access, by the base station, a capability database to determine, based on the identifier, the portion of UE capabilities for features and band combinations supported by the UE.

A method of wireless communication, comprising:

• accessing, by a user equipment (UE), a capability database to determine an identifier that identifies a portion of UE capabilities for features and band combinations supported by the UE for a mode of operation of multiple modes of operation of the UE;
• determining, by the UE, UE capabilities to be reported to a network based on one or more of:
• one or more enquiries from the network, received system information, a home operator policy, configuration associated with public land mobile network (PLMN) information of one or more networks, a user preference, or a service type;
• and
• transmitting, by the UE, the determined UE capabilities and the identifier.

A wireless communication apparatus, comprising:

• accessing, by a user equipment (UE), a capability database to determine an identifier that identifies a portion of UE capabilities for features and band combinations supported by the UE for a mode of operation of multiple modes of operation of the UE;
• means for determining, by the UE, UE capabilities to be reported to a network based on one or more of:
• one or more enquiries from the network, received system information, a home operator policy, configuration associated with public land mobile network (PLMN) information of one or more networks, a user preference, or a service type;
• and
• means for transmitting, by the UE, the determined UE capabilities and the identifier.

A wireless communication apparatus, comprising:

• at least one computer processor;
• and
• a memory coupled to the at least one computer processor, wherein the at least one computer processor is configured to:
• access, by a user equipment (UE), a capability database to determine an identifier that identifies a portion of UE capabilities for features and band combinations supported by the UE for a mode of operation of multiple modes of operation of the UE;
• determine, by the UE, UE capabilities to be reported to a network based on one or more of:
• one or more enquiries from the network, received system information, a home operator policy, configuration associated with public land mobile network (PLMN) information of one or more networks, a user preference, or a service type;
• and
• transmit, by the UE, the determined UE capabilities and the identifier.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
