Abstract

The present disclosure presents a method and apparatus for reducing power consumption during a voice communication in a user equipment (UE). For example, the method may include receiving a plurality of frames associated with the voice communication. Further, such an example method may include determining whether a frame pattern based at least on the received plurality of frames corresponds to a transition from a speech burst period to a non-speech period, and disabling a portion of a receiver subsystem at the UE for at least a portion of a frame associated with the non-speech period. As such, the power consumption in a UE may be reduced.

Claims

1. A method for reducing power consumption during a voice communication at a user equipment (UE), comprising:

receiving a plurality of frames associated with the voice communication;

determining, based at least on the received plurality of frames, whether a frame pattern corresponds to a first frame pattern indicating a transition from a speech burst period to a non-speech period and a second frame pattern indicating continuation of the non-speech period, wherein the first frame pattern includes a first silence insertion descriptor (SID) frame followed by one or more null frames and the second frame pattern includes a second SID frame followed by seven null frames; and

disabling a portion of a receiver subsystem at the UE for at least a portion of a null frame of the second frame pattern.

2. The method of claim 1, wherein the disabling comprises:

disabling the portion of the receiver subsystem for alternate null frames of the second frame pattern.

3. The method of claim 1, further comprising:

detecting a first null frame of the second frame pattern; and

disabling the portion of the receiver subsystem for a portion of a second null frame of the second traffic frame pattern that immediately follows the first null frame.

4. The method of claim 1, further comprising:

determining that a first null frame of the second frame pattern is time aligned with a first portion of a control channel frame, the first portion of the control channel frame comprising at least a beginning of the control channel frame; and

disabling the portion of the receiver subsystem for at least a portion of a second null frame of the second frame pattern that immediately follows the first null frame.

5. The method of claim 1, further comprising:

receiving additional frames of the second frame pattern.

6. The method of claim 1, further comprising:

decoding a null frame of the second frame pattern after receiving a subset of data of the null frame; and

terminating the decoding of the null frame when a cyclic redundancy check (CRC) based on the subset is successful.

7. The method of claim 1, further comprising:

determining a probability of a frame of the second frame pattern being a null frame based on a subset of data of the frame;

comparing the probability to a null frame confidence threshold; and

disabling the portion of the receiver for a remainder of the frame in response to determining that the probability exceeds the null frame confidence threshold.

8. The method of 7, wherein the disabling further comprises:

disabling the portion of the receiver subsystem for a remainder of the null frame when a cyclic redundancy check (CRC) based on the subset is successful.

9. The method of claim 8, further comprising:

sending, to a voice frame decoder of the UE, a frame quality indicator that indicates successful receipt of a frame when receipt of a portion of the frame was skipped due to the disabling of the portion of the receiver subsystem.

10. The method of claim 9, further comprising:

generating a comfort noise according to a most recent SID update frame based on the frame quality indicator without recognizing that the receipt of the traffic frame was skipped due to the disabling of the receiver.

11. An apparatus for reducing power consumption during a voice communication at a user equipment (UE), comprising:

means for receiving a plurality of frames associated with the voice communication;

means for determining, based at least on the received plurality of frames, whether a frame pattern corresponds to a first frame pattern indicating a transition from a speech burst period to a non-speech period and a second frame pattern indicating continuation of the non-speech period, wherein the first frame pattern includes a first silence insertion descriptor (SID) frame followed by one or more null frames and the second frame pattern includes a second SID frame followed by seven null frames; and

means for disabling a portion of a receiver subsystem at the UE for at least a portion of a null frame associated with of the second frame pattern.

12. The apparatus of claim 11, wherein the means for disabling is further configured to disable the portion of the receiver subsystem for alternate null frames of the second frame pattern.

13. A non-transitory computer readable medium storing computer executable code for reducing power consumption during a voice communication at a user equipment (UE), comprising:

code for receiving a plurality of frames associated with the voice communication;

code for determining, based at least on the received plurality of frames, whether a frame patterns corresponds to a first frame pattern indicating a transition from a speech burst period to a non-speech period and a second frame pattern indicating continuation of the non-speech period, wherein the first frame pattern includes a first silence insertion descriptor (SID) frame followed by one or more null frames and the second frame pattern includes a second SID frame followed by seven null frames; and

code for disabling a portion of a receiver subsystem at the UE for at least a portion of a null of the second frame pattern.

14. The computer readable medium of claim 13, wherein the code for the disabling further comprises code for disabling the portion of the receiver subsystem for alternate null frames of the second frame pattern.

15. The computer readable medium of claim 13, further comprising:
