Abstract

A method for control of data transmission in a wireless communication system includes receiving, by an application, from a modem, information indicative of a radio coverage condition, where a user equipment (UE) includes the application and the modem; based on the received information, determining that the UE is in an enhanced coverage state; and in response to the determining, controlling uplink data transmission by the modem to reduce power consumption of the UE.

First claim

The invention claimed is:

1. A method, comprising:
receiving, by an application, from a modem, information indicative of a radio coverage condition, wherein a user equipment (UE) includes the application and the modem;
based on the received information, determining that the UE is in an enhanced coverage state; and
in response to the determining, controlling uplink data transmission by the modem, wherein the controlling uplink data transmission comprises refraining from sending uplink data when at least one of the following occurs:
the UE is in one of a set of predefined coverage enhancement levels, coverage classes, or coverage enhancement modes, a data repetition indicator at the UE is above a predefined repetition threshold, a signal strength at the UE is below a predefined signal strength threshold, or a signal quality at the UE is below a predefined signal quality threshold;
the uplink data has a predefined data type;
the uplink data is associated with at least one of a predefined Quality of Service (QoS) indicator, a predefined priority level, or a predefined bit rate information;
a predefined timer associated with the uplink data transmission has not expired;
a counter associated with the uplink data transmission has reached a predefined counter threshold;
the UE is moving;
a battery level of the UE is higher than a first threshold;
a battery level of the UE is lower than a second threshold; or
the UE is not plugged into a power outlet.

2. The method of claim 1 , wherein the received information comprises at least one of a coverage enhancement level, a coverage enhancement mode, a coverage class, a data repetition indicator, a signal strength, or a signal quality.

3. The method of claim 1 , further comprises:
receiving speed information from a location sensor or an accelerometer of the UE; and
based on the speed information, determining whether the UE is moving.

4. The method of claim 3 , wherein receiving speed information is responsive to a query sent by the application to the location sensor or the accelerometer.

5. The method of claim 1 , further comprising:
receiving battery information from an operating system, a device interface, or a battery sensor of the UE; and
based on the battery information, determining whether the battery level of the UE is higher than the first threshold or lower than the second threshold, or whether the UE is plugged into a power outlet.

6. The method of claim 5 , wherein receiving battery information is responsive to a query sent by the application to the operating system, the device interface, or the battery sensor.

7. The method of claim 1 , further comprising:
receiving, at the UE and from a network node, configuration information including an indication that the UE is configured to control uplink data transmission and parameters associated with controlling the uplink data transmission.

8. The method of claim 1 , wherein receiving information indicative of a radio coverage condition is responsive to a query sent by the application to the modem.

9. The method of claim 8 , wherein the query for information indicative of a radio coverage condition is conveyed in a first attention (AT) command.

10. The method of claim 1 , wherein the information indicative of a radio coverage condition is conveyed in a second AT command.

11. The method of claim 1 , further comprising:
receiving, from the modem, information indicative of a radio coverage condition when the radio coverage condition changes.

12. A user equipment (UE), comprising:
a memory; and
at least one hardware processor communicatively coupled with the memory and configured to::
receive, by an application, from a modem, information indicative of a radio coverage condition, wherein the UE includes the application and the modem;
based on the received information, determine that the UE is in an enhanced coverage state; and
in response to the determining, control uplink data transmission by the modem, wherein the controlling uplink data transmission comprises refraining from sending uplink data when at least one of the following occurs:
the UE is in one of a set of predefined coverage enhancement levels, coverage classes, or coverage enhancement modes, a data repetition indicator at the UE is above a predefined repetition threshold, a signal strength at the UE is below a predefined signal strength threshold, or a signal quality at the UE is below a predefined signal quality threshold;
the uplink data has a predefined data type;
the uplink data is associated with at least one of a predefined Quality of Service (QoS) indicator, a predefined priority level, or a predefined bit rate information;
a predefined timer associated with the uplink data transmission has not expired;
a counter associated with the uplink data transmission has reached a predefined counter threshold;
the UE is moving;
a battery level of the UE is higher than a first threshold;
a battery level of the UE is lower than a second threshold; or
the UE is not plugged into a power outlet.

13. The UE of claim 12 , wherein the received information comprises at least one of a coverage enhancement level, a coverage enhancement mode, a coverage class, a data repetition indicator, a signal strength, or a signal quality.

14. The UE of claim 12 , wherein the at least one hardware processor is further configured to:
receive speed information from a location sensor or an accelerometer of the UE; and
based on the speed information, determine whether the UE is moving.

15. The UE of claim 14 , wherein the speed information is received in response to a query sent by the application to the location sensor or the accelerometer.

16. The UE of claim 12 , wherein the at least one hardware processor is further configured to:
receive battery information from an operating system, a device interface, or a battery sensor of the UE; and
based on the battery information, determine whether the battery level of the UE is higher than the first threshold or lower than the second threshold, or whether the UE is plugged into a power outlet.

17. The UE of claim 12 , wherein the at least one hardware processor is further configured to:
receive, at the UE and from a network node, configuration information including an indication that the UE is configured to control uplink data transmission and parameters associated with controlling the uplink data transmission.

18. The UE of claim 12 , wherein the information indicative of a radio coverage condition is conveyed in a second AT command.

19. The UE of claim 12 , wherein the at least one hardware processor is further configured to:
receive, from the modem, information indicative of a radio coverage condition when the radio coverage condition changes.

20. A tangible, non-transitory computer-readable medium containing instructions which, when executed, cause a user equipment (UE) to perform operations comprising:
receiving, by an application, from a modem, information indicative of a radio coverage condition, wherein a user equipment (UE) includes the application and the modem;
based on the received information, determining that the UE is in an enhanced coverage state; and
in response to the determining, controlling uplink data transmission by the modem, wherein the controlling uplink data transmission comprises refraining from sending uplink data when at least one of the following occurs:
the UE is in one of a set of predefined coverage enhancement levels, coverage classes, or coverage enhanceme
