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.

- 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.
