==DEVICE AND METHOD FOR HANDLING MULTIPLE SIM TRANSMISSION POWER RESTRICTIONS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18087399 titled 'DEVICE AND METHOD FOR HANDLING MULTIPLE SIM TRANSMISSION POWER RESTRICTIONS

==Simplified Explanation==

The patent application abstract describes a method for user equipment to transmit signals using multiple SIMs and perform power back-off when operating in MuSIM mode.

* User equipment can transmit signals using multiple SIMs concurrently.
* When user equipment decides to perform power back-off in MuSIM operation, it sends an indication to each network corresponding to each SIM.
* If a network supports MuSIM operation, user equipment sends an indication (M-MPR indication) that it is performing power back-off due to MuSIM operation.
* If a network does not support MuSIM operation, user equipment uses a legacy power back-off indication (P-MPR indication) to indicate that it is performing power back-off.

---

### Potential Applications
* Mobile devices with multiple SIM cards
* Networks supporting MuSIM operation

### Problems Solved
* Efficient power management in multi-SIM devices
* Compatibility with legacy networks

### Benefits
* Improved power efficiency
* Seamless operation in networks with different capabilities


==Original Abstract Submitted==

User equipment to transmit signals (e.g., concurrently) using multiple SIMs. If the user equipment determines to perform transmission power back-off due to operating using the multiple SIMs (MuSIM operation), the user equipment sends an indication to each network corresponding to each SIM that it is performing the power back-off. If a network supports MuSIM operation, then the user equipment sends an indication that it is performing the power back-off due to MuSIM operation (e.g., an MuSIM Maximum Power Reduction (M-MPR) indication). For such a network, it is assumed that the M-MPR indication would be standardized under an applicable specification. If a network does not support MuSIM operation (e.g., a legacy network), then the user equipment leverages a legacy power back-off indication (e.g., a Power Management Maximum Power Reduction (P-MPR) indication) to indicate to the network that it is performing a power back-off.
