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;
receive, from a base station of the cellular network, an indication of a selected bearer configuration including a range of values for at least one split bearer parameter; and
while transmitting data to the base station:
dynamically adjust the at least one split bearer parameter within the range of values, wherein said dynamically adjusting includes using a first value of the at least one split bearer parameter at a first time and using a second value of the at least one split bearer parameter at a second time.
2. The apparatus of claim 1 , wherein the selected bearer configuration further includes an initial value for the at least one split bearer parameter.
3. The apparatus of claim 1 , wherein the at least one split bearer parameter includes a data split threshold.
4. The apparatus of claim 3 , wherein said dynamically adjusting includes adjusting the data split threshold in response to detecting a change in radio conditions.
5. The apparatus of claim 1 , wherein the at least one split bearer parameter includes an offloading ratio.
6. The apparatus of claim 1 , wherein the processor is further configured to cause the UE to transmit information to the base station comprising a preference for a bearer configuration.
7. The apparatus of claim 6 , wherein the preference for the bearer configuration is based on one or more of:
battery level of the UE;
thermal status of the UE;
thermal stats of a component of the UE;
one or more active application; or
whether the UE is locked or actively in use.
8. The apparatus of claim 6 , wherein the preference for the bearer configuration comprises a first preference for uplink and a second preference for downlink, the second preference independent of the first preference.
9. The apparatus of claim 6 , wherein the preference for the bearer configuration comprises a first split threshold range for a first radio access technology (RAT).
10. The apparatus of claim 9 , wherein the preference for the bearer configuration further comprises a second split threshold range for a second RAT.
11. The apparatus of claim 9 , wherein the preference for the bearer configuration further comprises a preferred offloading ratio for the first RAT.
12. The apparatus of claim 6 , wherein the preference for the bearer configuration comprises a preferred primary radio link control (RLC) entity for a split bearer.
13. The apparatus of claim 1 , wherein the processor is further configured to cause the UE to:
dynamically indicate, to the base station, information for adapting a downlink split bearer parameter; and
receive downlink transmissions from the base station according to the downlink split bearer parameter.
14. The apparatus of claim 1 , further comprising a radio operably coupled to the processor.
15. A method, comprising:
entering a dual connectivity mode with a cellular network;
receiving, from a base station of the cellular network, an indication of a selected bearer configuration including a range of values for at least one split bearer parameter; and
while transmitting data to the base station:
dynamically adjusting the at least one split bearer parameter within the range of values, wherein said dynamically adjusting includes using a first value of the at least one split bearer parameter at a first time and using a second value of the at least one split bearer parameter at a second time.
16. The method of claim 15 , wherein the at least one split bearer parameter includes a data split threshold.
17. The method of claim 16 , wherein said dynamically adjusting includes adjusting the data split threshold in response to detecting a change in radio conditions.
18. A method, comprising:
entering a dual connectivity mode with a user equipment (UE);
transmitting, to the UE, an indication of a selected bearer configuration including a range of values for at least one split bearer parameter; and
while transmitting data to the UE:
dynamically adjusting the at least one split bearer parameter within the range of values, wherein said dynamically adjusting includes using a first value of the at least one split bearer parameter at a first time and using a second value of the at least one split bearer parameter at a second time.
19. The method of claim 15 , further comprising:
transmitting, to the UE, a second indication of a second selected bearer configuration including a second range of values for a second split bearer parameter; and
receiving data from the UE:
according to a third value of the second split bearer parameter at a third time; and
according to a fourth value of the second split bearer parameter at a fourth time.
20. The method of claim 15 , wherein said dynamically adjusting is in response to one or more indications from the UE.
