DUAL-SIM WIRELESS COMMUNICATIONS DEVICE AND METHOD FOR MITIGATING RECEIVER DESENSE IN DUAL-ACTIVE OPERATION

摘要

Aspects of the disclosure provide for an access terminal configured to enable communication with two or more wireless communications networks simultaneously. According to some aspects of the disclosure, an access terminal (e.g., dual-SIM access terminal) can be active simultaneously on both networks with reduced interference between transmission and reception. A number of different techniques for mitigating desense on a victim's Rx are illustrated in this disclosure with a GSM aggressor and an EV-DO victim as non-limiting examples. Other aspects, embodiments, and features are also claimed and described

主权项

1. A method of mitigating receiver desense at a dual-SIM access terminal during dual-active mode, comprising:
determining a transmitting time period for transmitting first data using a first radio access circuit of a first radio access technology (RAT); estimating a percentage of second data to be interfered by the transmission of the first data during the transmitting time period, the second data being to be received using a second radio access circuit of a second RAT; determining an effective signal-to-noise ratio (SNR) based on the estimated percentage; and sending a DRC request based on the effective SNR using the second radio access circuit.
