Abstract: Systems and methodologies are described that effectuate establishment of an IPSec tunnel for utilization in a wireless communication environment. IPSec establishment procedures on home base stations can be used to establish IPSec tunnels between home base stations situated on open access sectors of wireless communication environments and packet data interworking function components positioned at the contiguity of secured segments of the wireless communication environments. Moreover, high rate packet data point-to-point protocol challenge-handshake authentication protocols can be directed through the IPSec tunnels to facilitate authentication of access terminals associated with the home base stations in order to facilitate further communications with components dispersed within secure areas of wireless communication environments. Further, international mobile subscriber identities (IMSI) affiliated with access terminals associated with home base stations can be used to identify packet data serving nodes with which to establish communications between home base stations and packet data serving nodes.

Abstract: Methods, systems and devices for prioritizing communication technologies to allocate resources in a mobile device. The mobile device may employ a dual subscription, dual active (DSDA) configuration in which two subscriptions may be associated with concurrently active communications, such as voice or data calls. The mobile device may identify current states that indicate the type of communications associated with the subscriptions. In an embodiment, an applications processor within the mobile device may perform the state identifications. The mobile device may determine priorities of the concurrently active subscriptions based on the identified states. In an embodiment, the priorities may be determined by a modem processor within the mobile device. When the priorities are determined to be the same, the mobile device may perform a tiebreaker algorithm to further identify priorities. Based on the determined priorities, the mobile device may allocate resources to favor the subscription with the higher priority.

Abstract: The various embodiments provide methods implemented in a MSMA communication device for managing a victim subscription's de-sense by proactively implementing an RF coexistence management strategy on the victim subscription when an RF coexistence event starts. In various embodiments, a MSMA communication device may implement an RF coexistence management strategy by determining when an aggressor subscription will de-sense a victim subscription and configuring the victim to anticipate and mitigate de-sense during the aggressor's transmissions. Thus, the various embodiments may provide dramatic improvements to the victim's overall reception performance and overall user experience.

Abstract: Disclosed are systems and techniques for wireless communications. For instance, a wireless device may receive a signal from a first wireless network while the wireless device is in an idle mode; determine, from the received signal, a signal to noise ratio (SNR) and a doppler shift; retrieve stored network capability information; and estimate, based on the SNR, the doppler shift, and the stored network capability information, a throughput of the first wireless network.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for determining a transmit power based on a pattern and/or future conditions for a transmission while maintaining radio frequency (RF) exposure compliance. An example method generally includes obtaining a pattern associated with one or more first transmissions, determining a transmit power for one or more second transmissions based at least in part on the pattern and an RF exposure limit, and transmitting the one or more second transmissions at the determined transmit power.

Abstract: Certain aspects of the present disclosure are generally directed to extended signaling protocols for multi-subscriber identity module (MSIM) user-equipment (UE) for new radio (NR). For example, certain aspects provide a method for wireless communication by a UE. The method generally includes receiving a first message from a network entity enquiring regarding information associated with a multi-subscriber identify module (SIM) capability of the UE, determining the information associated with the multi-SIM capability of the UE in response to the inquiry from the network entity, and communicating one or more messages to indicate the information regarding the multi-SIM capability to the network entity.
