First Claim
Patent Images
1. A method of mitigating receiver desense at a dual-SIM access terminal during dual-active mode, comprising:
- during a transmitting time period, transmitting first data using a first radio access circuit of a first radio access technology (RAT);
during at least a portion of the transmitting time period, receiving second data using a second radio access circuit of a second RAT;
storing the second data in a memory;
determining a desense value indicative of a degree of desense on the reception of the second data caused by the transmission of the first data; and
selectively nulling the second data in the memory based on the desense value.

Abstract
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.
