Abstract

Aspects of the disclosure provide methods and apparatus for dynamically assigning signal paths to multiple subscriptions in a user equipment (UE) that supports dual subscription dual active (DSDA) communications. The dynamic assignment of signal paths provide dynamic implementation of power classes for uplink transmissions based on communication parameters of the networks associated with the dual subscriptions.

First claim

What is claimed is:

1. A method of wireless communication at a user equipment (UE), comprising:
determining one or more communication parameters associated with one or more of a first subscription associated with a first subscription identity module (SIM) or a second subscription associated with a second SIM, the first subscription enabling wireless communications between the UE and a first network, the second subscription enabling wireless communications between the UE and a second network;
estimating a transmit power or a power requirement for uplink transmission by the UE based on the one or more communication parameters; and
assigning one of a first signal path or a second signal path to the first subscription based on the estimated transmit power or power requirement, wherein the first signal path is associated with a first hardware configuration supporting a first maximum transmit power for uplink transmissions, wherein the second signal path is associated with a second hardware configuration supporting a second maximum transmit power for uplink transmissions, and wherein the first maximum transmit power is a higher power than the second maximum transmit power.

2. The method of claim 1 , further comprising receiving, from the first network, a first communication parameter of the one or more communication parameters, wherein the first communication parameter is indicative of one or more of a bandwidth or a modulation order for uplink transmissions by the UE to the first network.

3. The method of claim 2 , further comprising:
estimating the transmit power for uplink transmissions by the UE based on one or more of the bandwidth or the modulation order; and
assigning the first signal path to the first subscription if the estimated transmit power for uplink transmissions by the UE is greater than the second maximum transmit power; or
assigning the second signal path to the first subscription if the estimated transmit power for uplink transmissions by the UE is less than the second maximum transmit power.

4. The method of claim 1 , wherein determining one or more communication parameter associated with one or more of the first subscription or the second subscription further comprises:
determining that both of the first network and the second network are in an idle state; and
estimating, in response to the determination that both the first network and the second network are in the idle state: (i) a first uplink power requirement for uplink transmissions in the first network, and (ii) a second uplink power requirement for uplink transmissions in the second network.

5. The method of claim 4 , further comprising:
assigning the first signal path to the first subscription if the estimated first uplink power requirement is greater than the second maximum transmit power; or
assigning the second signal path to the first subscription if the estimated first uplink power requirement is less than the second maximum transmit power.

6. The method of claim 4 , further comprising:
assigning the first signal path to the second subscription if the estimated second uplink power requirement is greater than the second maximum transmit power; or
assigning the second signal path to the second subscription if the estimated second uplink power requirement is less than the second maximum transmit power.

7. The method of claim 4 , wherein:
estimating the first uplink power requirement comprises measuring downlink radio conditions of the first network; and
estimating the second uplink power requirement comprises measuring downlink radio conditions of the second network, wherein the downlink radio conditions comprise one or more of received signal power or a received signal quality.

8. The method of claim 1 , wherein determining one or more communication parameter associated with one or more of the first subscription or the second subscription further comprises:
determining that the first network is in a connected state and the second network is in an idle state; and
assigning the first signal path to the first subscription.

9. The method of claim 1 , wherein determining one or more communication parameters associated with one or more of the first subscription or the second subscription further comprises determining that both of the first network and the second network are in a connected state, wherein the method further comprises:
in response to the determination that both the first network and the second network are in the connected state:
estimating (i) a first uplink power requirement for uplink transmissions in the first network, and (ii) a second uplink power requirement for uplink transmissions in the second network; and
determining one or more of a priority or a quality of service associated with data communicated using each of the first subscription and the second subscription.

10. The method of claim 9 , further comprising:
determining a difference between the estimated first uplink power requirement and the estimated second uplink power requirement;
if the difference between the estimated first uplink power requirement and the estimated second uplink power requirement is greater than a threshold value, assigning the first signal path to one of the first subscription or the second subscription corresponding to the greater of the estimated first uplink power requirement and the estimated second uplink power requirement; and
if the difference between the estimated first uplink power requirement and the estimated second uplink power requirement is less than a threshold value, assigning the first signal path to one of the first subscription or the second subscription corresponding to data having a higher one or more of the priority or the quality of service relative to the other of the first subscription or the second subscription.

11. The method of claim 1 , wherein the one or more communication parameters comprise one or more of:
a co-existence constraint associated with at least one of the first network and the second network;
a safety constraint associated with the UE; or
a specific absorption rate (SAR) constraint associated with the UE.

12. The method of claim 1 , wherein the UE supports a dual subscription dual active (DSDA) mode, wherein communications between the UE and the first network are enabled by a first subscriber identity module (SIM), and wherein communications between the UE and the second network are enabled by a second SIM.

13. The method of claim 1 , wherein the transmit power is a first transmit power estimated based at least in part on a first communication parameter associated with the first subscription, and wherein the method further comprises:
estimating a second transmit power based at least in part on a second communication parameter associated with the second subscription, wherein the first signal path is assigned to the first subscription based further on: (i) the first transmit power being a higher power than the second transmit power, and (ii) the first maximum transmit power being a higher power than the second maximum transmit power.

14. An apparatus for wireless communications, comprising:
a memory comprising instructions; and
one or more processors configured to execute the instructions and cause the apparatus to:
determine one or more communication parameters associated with one or more of a first subscription associated with a first subscription identity module (SIM) or a second subscription associated with a second SIM, the first subscription enabling wireless communications between the apparatus and a first network, the second subscription enabling wireless communications between the
