Negotiation on bearer type configurations
Apparatuses, systems, and methods for a wireless device to perform negotiation of bearer type configuration and/or related parameters. A user equipment device (UE) and/or network may determine a bearer configuration and/or other parameters based on information or measurements of the UE. The UE and the BS may exchange data using a negotiated configuration.
1. An apparatus, comprising:
a processor configured to cause a user equipment device (UE) to:
enter a dual connectivity mode with a cellular network, wherein the dual connectivity mode includes connections to a master cell group and a secondary cell group;
transmit, to a base station of the cellular network, information including a preference for a suggested uplink split bearer configuration for a bearer connecting the UE to the master cell group and the secondary cell group, wherein the information includes a data split threshold, wherein for uplink transmissions less than the data split threshold amount, uplink transmission may occur via only a primary radio link control (RLC) entity;
receive, from the base station, an indication of a selected uplink bearer configuration; and
transmit, to the base station, uplink data according to the selected uplink bearer configuration.
2. The apparatus of claim 1 , wherein the information further includes a suggested downlink bearer configuration.
3. The apparatus of claim 1 , wherein the suggested uplink split bearer configuration includes a preferred radio access technology for uplink transmission.
4. The apparatus of claim 1 , wherein the suggested uplink split bearer configuration includes an offloading ratio.
5. The apparatus of claim 1 , wherein the information is transmitted via a medium access control (MAC) control element (CE).
6. The apparatus of claim 1 , wherein the suggested uplink split bearer configuration is based on a thermal and/or power status of the UE.
7. The apparatus of claim 1 , wherein the suggested uplink split bearer configuration is based on a measurement of the master cell group.
8. The apparatus of claim 1 , wherein the suggested uplink split bearer configuration is based on a measurement of a primary secondary cell (PSCell) of the secondary cell group.
9. The apparatus of claim 1 , wherein the suggested uplink split bearer configuration is based on a comparison of conditions on the master cell group and conditions on the secondary cell group.
10. A user equipment device (UE), comprising:
a radio; and
a processor operably coupled to the radio and configured to cause the UE to:
enter a dual connectivity mode with a cellular network, wherein the dual connectivity mode includes connections to a master cell group and a secondary cell group;
transmit, to a base station of the cellular network, information including a preference for a suggested uplink split bearer configuration for a bearer connecting the UE to the master cell group and the secondary cell group, wherein the information includes a data split threshold, wherein for uplink transmissions less than the data split threshold amount, uplink transmission may occur via only a primary radio link control (RLC) entity;
receive, from the base station, an indication of a selected uplink bearer configuration; and
transmit, to the base station, uplink data according to the selected uplink bearer configuration.
11. The UE of claim 10 , wherein the information further includes a suggested downlink bearer configuration.
12. The UE of claim 10 , wherein the suggested uplink split bearer configuration includes a preferred radio access technology for uplink transmission.
13. The UE of claim 10 , wherein the suggested uplink split bearer configuration includes an offloading ratio.
14. The UE of claim 10 , wherein the information is transmitted via a medium access control (MAC) control element (CE).
15. The UE of claim 10 , wherein the suggested uplink split bearer configuration is based on a thermal and/or power status of the UE.
16. The UE of claim 10 , wherein the suggested split bearer configuration is based on a measurement of the master cell group.
17. The UE of claim 10 , wherein the suggested uplink split bearer configuration is based on a measurement of a primary secondary cell (PSCell) of the secondary cell group.
18. The UE of claim 10 , wherein the suggested uplink split bearer configuration is based on a comparison of conditions on the master cell group and conditions on the secondary cell group.
19. A method, comprising:
at a cellular network:
entering a dual connectivity mode with a user equipment device (UE), wherein the dual connectivity mode includes connections between from the UE to a master cell group and a secondary cell group;
receiving, from the UE, information including a preference for a suggested uplink split bearer configuration for a bearer connecting the UE to the master cell group and the secondary cell group, wherein the information includes a data split threshold, wherein for uplink transmissions less than the data split threshold amount, uplink transmission may occur via only a primary radio link control (RLC) entity;
transmitting, to the UE, an indication of a selected uplink bearer configuration; and
receiving, from the UE, uplink data according to the selected uplink bearer configuration.
20. The method of claim 19 , wherein the information is transmitted via a medium access control (MAC) control element (CE).
