Abstract

Embodiments described herein relate to extending an awake period (on duration) or an inactivity timer duration in a Connected Discontinuous Reception (CDRX) mode for a first subscription based on activities of a second subscription. A method according to some embodiments includes determining that the awake period of the CDRX cycle associated with the first subscription collides with the activities of the second subscription, and extending the awake period by an extended awake period in response to determining that the awake period collides with the activities of the second subscription. In addition, a method according to some embodiments includes determining that the inactivity timer duration collides with the activities of the second subscription, and extending the inactivity timer duration for an extended inactivity timer duration in response to determining that the inactivity timer duration collides with the activities of the second subscription.

First claim

What is claimed is:

1 . A method for a wireless communication device having a first Subscriber Identity Module (SIM) associated with a first subscription and a second SIM associated with a second subscription to manage communications over the first subscription and the second subscription, the method comprising:
determining that data transfer during an awake period of a Connected Discontinuous Reception (CDRX) cycle associated with the first subscription collides with activities of the second subscription; and extending the awake period by an extended awake period in response to determining that the data transfer during the awake period collides with the activities of the second subscription.

2 . The method of claim 1 , further comprising configuring a Radio Frequency (RF) resource of the wireless communication device to monitor downlink data in a Physical Downlink Shared Channel (PDSCH) during the awake period.

3 . The method of claim 2 , further comprising tuning the RF resource away from the first subscription to the second subscription for the activities of the second subscription.

4 . The method of claim 1 , wherein determining that the data transfer during the awake period collides with the activities of the second subscription comprises determining that at least a portion of the data transfer during the awake period collides with at least a portion of the activities of the second subscription.

5 . The method of claim 1 , wherein the activities of the second subscription comprises idle-mode reception activities of the second subscription.

6 . The method of claim 1 , wherein the idle-mode reception activities of the second subscription comprises receiving and decoding pages of the second subscription.

7 . The method of claim 1 , wherein extending the awake period by the extended awake period comprises configuring a Radio Frequency (RF) resource of the wireless communication device to monitor downlink data in a Physical Downlink Shared Channel (PDSCH) during the extended awake period.

8 . The method of claim 7 , further comprising:
receiving the downlink data in the PDSCH during the extended awake period, wherein the received downlink data corresponds to an identity of the wireless communication device; and continuously monitoring for downlink data in the PDSCH in response to receiving the downlink data during the extended awake period.

9 . The method of claim 1 , wherein the extended awake period occurs after a tune-away period corresponding to the activities of the second subscription.

10 . The method of claim 1 , wherein a length of the extended awake period is 8 ms.

11 . The method of claim 1 , wherein a length of the extended awake period is determined based on Hybrid Automatic Repeat Request (HARQ) processes.

12 . The method of claim 1 , wherein the first subscription is a Long Term Evolution (LTE) subscription associated with the CDRX.

13 . A wireless communication device, comprising:
at least one Radio Frequency (RF) resource; a processor operably connected to said at least one RF resource configured to connect to a first Subscriber Identity Module (SIM) associated with a first subscription and to a second SIM associated with a second subscription, and configured to:
determine that data transfer during an awake period of a Connected Discontinuous Reception (CDRX) cycle associated with the first subscription collides with activities of the second subscription; and
extend the awake period by an extended awake period in response to determining that the data transfer during the awake period collides with the activities of the second subscription; and
a memory.

14 . The wireless communication device of claim 13 , the processor is configured to extend the awake period by the extended awake period by configuring the at least one RF resource to monitor downlink data in a Physical Downlink Shared Channel (PDSCH) during the extended awake period.

15 . The wireless communication device of claim 14 , wherein the processor is further configured to:
receive the downlink data in the PDSCH during the extended awake period, wherein the received downlink data corresponds to an identity of the wireless communication device; and continuously monitor for downlink data in the PDSCH in response to receiving the downlink data during the extended awake period.

16 . A method for a wireless communication device having a first Subscriber Identity Module (SIM) associated with a first subscription and a second SIM associated with a second subscription to manage communications over the first subscription and the second subscription, the method comprising:
determining that an inactivity timer duration overlaps with the time the activities of the second subscription occur; and extending the inactivity timer duration for an extended inactivity timer duration in response to determining that the inactivity timer duration overlaps with the time the activities of the second subscription occur.

17 . The method of claim 16 , further comprising:
configuring a Radio Frequency (RF) resource of the wireless communication device to monitor downlink data in a Physical Downlink Shared Channel (PDSCH) during an awake period of a Connected Discontinuous Reception (CDRX) cycle associated with the first subscription; and receiving the downlink data during the awake period.

18 . The method of claim 16 , further comprising monitoring downlink data in a Physical Downlink Shared Channel (PDSCH) during the inactivity timer duration.

19 . The method of claim 18 , further comprising tuning the RF resource away from the first subscription to the second subscription for the activities of the second subscription.

20 . The method of claim 16 , wherein determining that the inactivity timer duration collides with the time the activities of the second subscription occur comprises determining that at least a portion of the inactivity timer duration collides with at least a portion of the time the activities of the second subscription occur.

21 . The method of claim 20 , wherein the at least a portion of the inactivity timer duration comprises an end duration of the inactivity timer duration, wherein the end duration comprises at least one subframe before expiration of the inactivity timer duration.

22 . The method of claim 21 , wherein the end duration comprises 8 subframes before the expiration of the inactivity timer duration.

23 . The method of claim 16 , wherein the activities of the second subscription comprises idle-mode reception activities of the second subscription.

24 . The method of claim 23 , wherein the idle-mode reception activities of the second mode comprises receiving and decoding pages of the second subscription.

25 . The method of claim 16 , wherein extending the inactivity timer duration for the extended inactivity timer duration comprises configuring a Radio Frequency (RF) resource of the wireless communication device to monitor downlink data in a Physical Downlink Shared Channel (PDSCH) during the extended inactivity timer duration.

26 . The method of claim 25 , further comprising:
receiving the downlink data during the extended inactivity timer duration; and extending the inactivity timer duration for an additional inactivity timer duration in response to receiving the downlink data during the extended inactivity timer duration.
