5G/NR - UE Capability

UE Capability in a Nutshell

What is it for ? UE capability is a RRC signaling mechanism by which UE can inform its capabilities to gNB
gNB request UE to inform about its capability by sending the message : UE Capability Enquiry and UE responds to this request by sending UE Capability Information message.
NR UE capability Information in general is much more complicated than LTE UE capability Information because NR Radio stack is more flexible and complex than LTE radio stack.
gNB may not want to get all the possible UE capability information and can restrict the type and amount of UE capability information by putting a specific requirements in UE capability Enquiry. The entire list of UE capabilities without any restriction can be too long and cause too much signaling overhead if it is transmitted in full size.
Some of the most important information on UE capability Information in NR would be : bandwidth information, Bandwidth(for single carrier) and Bandwidth Combination(for Carrier Aggregation), MIMO, Subcarrier Spacing etc.

UE Capability in Detail

The purpose (Function) of UE Capability Information in NR is same as LTE UE Capability Information. In LTE UE capability information carries the information in roughly two large category : RF/Physical layer information and Feature Group(FGI). NR also reports similar information (i.e, RF/PHY information and Feature sets) but much more diverse information than LTE.

For the details of the meaning of each IEs listed here, refer to 38.306. But to understand the exact meaning of the descriptions in 38.306, you would need to understand the whole NR specification... simply put, it would be life time job to understand the full details of what you see in the UE capability information. So.. don't be hurry.. take time trying to one at a time. The best way is to take a look at specific IEs that you are interested one at a time and find some examples as shown below and try to understand the detailed meaning based on 38.306 and all other related specification.

Example 01 : nr single band

UE Capability Information - NR

Following is the RRC message structure of UE capability Information message. But it may be too complicated and in many cases too confusing as well because of too many parameters and too complicated inter-dependencies among multiple parameters. I think the best way is to check out specific examples for various cases.

38.306 specifies the meaning of this IE as follows :

channelBWs-DL/channelBWs-UL :

Indicates for each subcarrier spacing whether the UE supports channel bandwidthslower than the maximum channel bandwidth as defined in TS 38.101-1 and TS 38.101-2 . If this parameter is not included, it mean that the UE supports the channel bandwidths among [5, 10, 15, 20, 25, 30, 40, 50, 60, 80, 100] in FR1 and [50, 100, 200] in FR2.

For FR1, the bits starting from the leading / leftmost bit indicate 5, 10, 15, 20, 25, 30, 40, 50, 60 and 80MHz. For FR2, the bits starting from the leading / leftmost bit indicate 50, 100 and 200MHz.

NOTE : it is assumed that the maximum bandwidth (in most case 100Mhz in FR1 SCS30, 50 Mhz in FR1 SCS 15, 400 Mhz FR2) is supported by default.

Example 15 : NSA Supportability - NAS Capability

For NSA, there should be two major feature should be supported. One is lower layer band combination and the other one is higher layer dual connectivity. Higher layer dual connectivity (i.e, dual connectivity with NR) is notified by a NAS message with a parameter calledDCNR. This feature is configured in UE network capability in Attach Request (in case of LTE) or Registration Request (in case of NR).

NOTE : This is for NSA Supportability with NAS point of view. For the lower layer capability of NSA Supportability, Refer to Example 16.

How to handle the ever increasing size of UE capability Information ? - RRC Segmentation

As far as I recall, I have seen many issues even from LTE only cases in later 3GPP release in terms of processing UE capability information in both UE and network (or network simulator) side.

Sometimes UE fails to generate the well structured UE capability information with huge set of features, especially when the number of carrier aggregation gets increased. And problems heppens in network side in similar situation failing to decode properly the lengthy and complicated UE capability Information message.

This issue has become even more serious in NR (both SA and NSA). NR UE capability features in NR is much more complicated than LTE. When the number of aggregated carrier gets increases, the size of the UE capability Information message exceeds the maximum size of RRC signaling message.

To workaround this situation, a new mechanism of RRC signaling is introduced. The new mechanism is called 'Segmented RRC Message'. For further details of this mechanism, I would like to share what Anupam Shrivastava kindly contributed as below.

With the introduction of new UE-capa every release the size of RRC is increasing( below study on UE-capa IE introduction with different 3gpp releases from Rel-15.1 till Rel-17) and in scenarios of CA, HO there are situations when the RRC size will exceed the limit for 9k bytes as explained above for the NR, to overcome this situation we need to fragment/segment the capa into smaller chunks for which Segmentation is introduced, though it comes with a cost of additional delay in UECapabilityinformation received by gNB , as gNB need extra time to receive all segments and then reassemble them.

The maximum supported size of a PDCP SDU is 9000 bytes. The maximum supported size of a PDCP Control PDU is 9000 bytes. So the UE capability Information with size greater than 9000 byte should be split into multiple rrc messages and then combined later.

The RRC message carrying each of the segment is as follows :

ULDedicatedMessageSegment-r16 ::= SEQUENCE {

criticalExtensions CHOICE {

ulDedicatedMessageSegment-r16 ULDedicatedMessageSegment-r16-IEs,

criticalExtensionsFuture SEQUENCE {}

}

ULDedicatedMessageSegment-r16-IEs ::= SEQUENCE {
