Embodiment Construction

[0019] Various embodiments will now be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References made to specific examples and implementations are for illustration purposes only and are not intended to limit the scope of the invention.

[0020] Various embodiments improve the performance of Multi-SIM Multi-Active (MSMA) wireless communication devices participating in simultaneous communication by enabling a first power saving mode in some dual-active scenarios. In various embodiments, an MSMA wireless communication device may be configured to use two or more power saving modes. A first power saving mode, an example of which is envelope tracking (ET), may provide maximum power consumption reduction of the power amplifier (ie, may cause the power amplifier to consume the least amount of current). For example, the second power saving mode may ...

Abstract

Various embodiments enable Multi-SIM Multiple Active (MSMA) when a first radio frequency (RF) resource is supporting data transmission for a communication network associated with a first SIM and a second RF resource is supporting a voice call in a discontinuous transmission mode. The communication device is capable of operating the power amplifier in a power saving envelope tracking mode. The MSMA communication device processor may monitor a second RF resource supporting the voice call for periods of silence, the power amplifier of the first RF resource may operate in a first power saving mode during the period of silence on the voice call, and when the second When the voice call on the RF resource is not in the silent period, the power amplifier of the first RF resource may operate in the second power saving mode. The period of silence may be determined by monitoring the protocol stack of the second RF resource for silence descriptor (SID) frames scheduled for transmission.

Description

Background technique [0001] Multiple Subscriber Identity Module (SIM) communication devices are becoming increasingly popular due to their flexibility in service options and other features. In various types of multi-SIM wireless communication devices, each modem stack associated with a subscriber may store information provided by its corresponding network operator in the SIM, which may allow the SIM to support the use of various communication services. For example, various wireless networks may be configured to handle different types of data, use different communication modes, implement different radio access technologies, and so on. One type of multi-SIM wireless communication device, known as a Dual-SIM Dual-Active (DSDA) device, is typically configured with a separate transmit / receive chain associated with each SIM, allowing the network to simultaneously correspond to two SIMs. Make an active connection. [0002] To enable communication in various networks, wireless commu...
