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 during dual-active mode at a dual-SIM access terminal, 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; and modifying a preamble detection process of the second data at the second radio access circuit based on the transmitting time period.
