## Abstract

Technology for improving the selection, transfer, and storage of user equipment (UE) radio capability information is disclosed. A cellular mobile network can be configured to identify radio-access-technology (RAT)-specific radio-capability information relating to RATs supported in the cellular mobile network and communicate the RAT-specific radio-capability information to a UE. The UE can use the RAT-specific radio-capability information to help determine which UE radio capability information to send to the network. In addition, the UE may store a list of supported frequency bands and/or supported frequency-band combinations (LOSB) indexed by network operators and use the list to help determine which UE radio capability information to send to the network. A network node may also selectively remove unnecessary information from UE radio capability information before storing the UE radio capability information at a mobility management entity (MME).

## Claims

### Claim at position 1

-20. (canceled)

### Claim 21

An apparatus of a user equipment (UE) operable to communicate radio access capability information, the apparatus comprising:
memory; and
one or more processors configured to:
decode, at the UE, a UE capability enquiry message received from a network, the UE capability enquiry message including a list of frequency bands that are supported in the network, and a maximum number of uplink carriers supported in the network;
create, at the UE, a list of frequency band combinations that are supported at the UE based in part on the UE capability enquiry message, wherein a number of carriers in an uplink for the frequency band combination does not exceed the maximum number of uplink carriers supported in the network; and
encode at the UE, a UE capability information message for transmission to the network that includes the list of frequency band combinations that are supported at the UE and the network.

### Claim 22 (depends on 21)

The apparatus of claim 21, further comprising a transceiver configured to:
receive the UE capability enquiry message from the network; and
transmit the UE capability information message to the network.

### Claim 23 (depends on 21)

The apparatus of claim 21, wherein the UE capability enquiry message further includes a maximum number of downlink carriers supported in the network.

### Claim 24 (depends on 23)

The apparatus of claim 23, wherein a number of carriers in a downlink for a frequency band combination in the list of frequency band combinations does not exceed the maximum number of downlink carriers supported in the network.

### Claim 25 (depends on 21)

The apparatus of claim 21, wherein the list of frequency band combinations are limited to the list of frequency bands that are supported in the network.

### Claim 26 (depends on 21)

The apparatus of claim 21, wherein the frequency band combinations that are included in the UE capability information message are carrier aggregation (CA) band combinations.

### Claim 27 (depends on 21)

The apparatus of claim 21, wherein the UE capability enquiry message is received at the UE via a radio resource control (RCC) signaling message.

### Claim 28 (depends on 21)

The apparatus of claim 21, wherein the UE capability enquiry message is received at the UE when the UE is in a connected mode.

### Claim 29

At least one non-transitory machine readable storage medium having instructions embodied thereon for a network node in a network to determine radio access capability information associated with a user equipment (UE), the instructions when executed by one or more processors cause the UE to perform the following:
