Abstract

A method, device, computer readable storage medium and integrated circuit for providing user equipment (UE) capability information to a network. The method includes receiving a request from a network for radio access capabilities of the UE, determining a first plurality of band combinations that the UE is capable of utilizing for communications with the network, determining a number of band combinations that are to be included with a message generated in response to the request, ordering the plurality of band combinations into a prioritized order of band combinations based on at least one priority factor, generating the message that includes the radio access capabilities, wherein the message includes a second plurality of band combinations that are based on the prioritized order and the number of band combinations that are to be included with a message and transmitting the message to the network.

First claim

What is claimed:

1. A method, comprising:
at a user equipment (UE):
receiving a request from a network for radio access capabilities of the UE;
determining a first plurality of band combinations that the UE is capable of utilizing for communications with the network;
determining a number of band combinations that are to be included with a message generated in response to the request;
ordering the plurality of band combinations into a prioritized order of band combinations based on at least two weighted priority factors, wherein the at least two weighted priority factors are (i) weighted differently and (ii) applied to each band combination of the plurality of band combinations;
generating the message that includes the radio access capabilities, wherein the message includes a second plurality of band combinations that are based on the prioritized order and the number of band combinations that are to be included with a message; and
transmitting the message to the network.

2. The method of claim 1 , where ordering the plurality of band combinations is further based on whether each of the plurality of band combination supports supplementary uplink.

3. The method of claim 2 , further comprising:
determining whether a predetermined condition is satisfied,
wherein when one or more band combinations support supplementary uplink and the predetermined condition is satisfied, the one or more band combinations are deprioritized, and
wherein when the one or more band combinations support supplementary uplink and the predetermined condition is not satisfied, the one or more band combinations are prioritized.

4. The method of claim 1 , wherein the at least two priority factors comprise two of a performance priority factor, a multiple input multiple output (MIMO) related priority factor, an LTE-NR dual-connectivity (ENDC) related priority factor or an internet protocol (IP) multimedia subsystem (IMS) priority factor.

5. The method of claim 4 , wherein the MIMO related priority factor comprises whether a band combination includes a band that supports intra-band component carriers and multiple input multiple output (MIMO) communication.

6. The method of claim 4 , wherein the MIMO related priority factor comprises whether a band combination includes a band that supports gapless measurements and multiple input multiple output (MIMO) communication.

7. The method of claim 4 , wherein the MIMO related priority factor comprises whether a band combination includes a band that supports uplink (UL) multiple input multiple output (MIMO) communication and 256 quadrature amplitude (256-QAM).

8. The method of claim 4 , wherein the MIMO related priority factor comprises whether a band combination includes a band that supports higher order receiver diversity (HORxD) and multiple input multiple output (MIMO) communication.

9. The method of claim 4 , wherein the MIMO related priority factor comprises whether a band combination includes a band combination that supports multiple input multiple output (MIMO) communication on a higher order band.

10. The method of claim 4 , wherein the ENDC related priority factor comprises whether a band combination includes a band combination that supports dynamic power sharing.

11. The method of claim 4 , wherein the ENDC related priority factor comprises whether a band combination includes a band combination that supports dual power amplifying.

12. The method of claim 4 , wherein the ENDC related priority factor comprises whether a band combination includes a band within frequency range 1 (FR1).

13. A user equipment (UE), comprising:
a transceiver configured to connect to a network; and
a processor configured to:
receive a request from the network for radio access capabilities of the UE;
determine a first plurality of band combinations that the UE is capable of utilizing for communications with the network;
determine a number of band combinations that are to be included with a message generated in response to the request;
order the plurality of band combinations into a prioritized order of band combinations based on at least two priority factors, wherein the at least two weighted priority factors are (i) weighted differently and (ii) applied to each band combination of the plurality of band combinations, wherein the at least two priority factors are evaluated by the UE; and
generate the message that includes the radio access capabilities, wherein the message includes a second plurality of band combinations that are based on the prioritized order and the number of band combinations that are to be included with a message,
wherein the transceiver is further configured to transmit the message to the network.

14. The UE of claim 13 , where ordering the plurality of band combinations is further based on whether each of the plurality of band combination supports supplementary uplink.

15. The UE of claim 14 , further comprising:
determining whether a predetermined condition is satisfied,
wherein when one or more band combinations support supplementary uplink and the predetermined condition is satisfied, the one or more band combinations are deprioritized, and
wherein when the one or more band combinations support supplementary uplink and the predetermined condition is not satisfied, the one or more band combinations are prioritized.

16. The UE of claim 13 , wherein the at least two priority factors comprises two of a performance priority factor, a multiple input multiple output (MIMO) related priority factor, an LTE-NR dual-connectivity (ENDC) related priority factor or an internet protocol (IP) multimedia subsystem (IMS) priority factor.

17. A method, comprising:
at a user equipment (UE):
receiving a request from a network for radio access capabilities of the UE;
determining a first plurality of band combinations that the UE is capable of utilizing for communications with the network based on a radio frequency band list;
ordering the plurality of band combinations into a prioritized order of band combinations based on the radio frequency band list, wherein the prioritized order of band combinations is based on at least two weighted priority factors wherein the at least two weighted priority factors are (i) weighted differently and (ii) applied to each band combination of the plurality of band combinations, wherein the at least two weighted priority factors include two or more of a number of Long-Term Evolution (LTE) component carriers (CCs), a number of 5G New Radio (NR) CCs, a total aggregated bandwidth, an accumulated number of layers for LTE CCs, an accumulated number of layers for 5G NR CCs, or any combination thereof, and wherein the ordering of the plurality of band combinations comprises determining, based on the least two weighted priority factors and their respective weights, that a first band combination has a higher potential peak performance than a second band combination and prioritizing the first band combination over the second band combination in the prioritized order of band combinations;
generating a message that includes the radio access capabilities, wherein the message includes the prioritized order of band combinations; and
transmitting the message to the network.

18. The method of claim 17 , further comprising:
determining whether any two or more of the plurality of band combinations have a same priority.

19. The method of claim 18 , further comprising:
when two or more of the plurality of band combinations have the same priority, determining a further priority for each of the two or mo
