Abstract: The present disclosure provides a method for a multi-subscriber identity module (SIM) wireless communication. The method includes receiving a communication request, performing a first wireless communication, and performing a second wireless communication. Receiving a communication request by a second SIM while in wireless communication is based on a first SIM is performed via a plurality of antennas. Performing a first wireless communication is based on the first SIM communicating via a first antenna group that is a portion of the plurality of antennas, in response to a number of antennas used for wireless communication based on the first SIM and the second SIM that is greater than a number of available antennas of a terminal. Performing a second wireless communication is based on the second SIM via a second antenna group while the first wireless communication is performed and the second group is different from the first antenna group.

Abstract: The devices, systems, and techniques described herein provide for efficient communications between devices to reduce power consumption while maintaining performance. In some aspects, a terminal may adjust a transmission power limit for transmitting signals to a base station to reduce power consumption at the terminal. In some examples, the terminal may adjust the transmission power limit based on a temperature of the terminal and a number of resource blocks allocated to the terminal (e.g., such that the temperature remains below a threshold). In some other examples, the terminal may adjust the transmission power limit based on a block error rate (BLER) (e.g., such that the BLER remains below a threshold while minimizing the transmission power limit). In some other examples, the terminal may adjust the transmission power limit based on an importance of one or more transmissions (e.g., to avoid wasting power on less important transmissions).
