Abstract: Methods are provided that enable mitigation of desense from a transmission on a first radio frequency (RF) resource associated with a first SIM to a receiver circuit of a second RF resource associated with a second SIM in the same device. A multi-SIM wireless device, such as a dual-SIM dual active (DSDA) device, may utilize characteristics of uplink and downlink signals to determine an optimal action that reduces interference from conflicting signals. Mitigating actions do not require involvement on the network side, and may greatly improve processing time for implementing interference prevention measures.

Abstract: A method is provided for conserving power on a wireless communication device having multi-subscription capabilities. Instead of scanning different paging channels for each of a plurality of subscriptions, power may be conserved by using a single paging channel from a serving access network for all paging messages from the plurality of subscriptions. The wireless communication device may provide a serving access network information for the plurality of subscriptions, where each of the plurality of subscriptions is associated with a different paging channel. The serving access network may select or obtain a single paging channel for all paging messages from different core networks associated with the plurality of subscriptions. The wireless communication device may be informed of the selected paging channel by the access network so it monitors for paging messages for all subscriptions on that selected paging channel only.

Abstract translation: 提供了一种用于在具有多订阅能力的无线通信设备上节省功率的方法。 代替为多个订阅中的每一个扫描不同的寻呼信道，可以通过对来自多个订阅的所有寻呼消息使用来自服务接入网络的单个寻呼信道来节省功率。 无线通信设备可以为多个订阅提供服务接入网络信息，其中多个订阅中的每个订阅与不同的寻呼信道相关联。 服务接入网络可以从与多个订阅相关联的不同核心网络的所有寻呼消息中选择或获得单个寻呼信道。 无线通信设备可以由接入网络通知所选择的寻呼信道，因此它仅监视所选择的寻呼信道上的所有订阅的寻呼消息。

Abstract: The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing robust transmit (Tx) processing to resolve radio frequency coexistence interference between two subscriptions operating on the DSDA device. The DSDA device may detect when one subscription (the “aggressor”) de-senses the other subscription (the “victim”) as a result of the aggressor's transmissions, and in response, implement robust Tx processing to mitigate the effects of de-sense on the victim.
