Abstract: To reduce the effectiveness of eavesdropping attacks, a filler such as one utilized in a data frame for link-layer LAPDm signaling may be dynamically selected to utilize a first bit pattern (first filler) generated utilizing a first algorithm when the transmissions are unencrypted, and to utilize a second bit pattern (second filler) generated utilizing a second algorithm different from the first algorithm when the transmissions are encrypted.

Abstract: Apparatus and methods are disclosed to provide for a multi-SIM wireless user equipment configured for discontinuous reception (DRX) utilizing two or more subscriptions, which may be in different radio access technologies. The user equipment is configured to originate a call using one subscription, to the same user equipment over another subscription. During the duration of a blanking window, statistics corresponding to repetitions of incoming page messages are recorded and analyzed to determine repetition behavior by the network of page messages. In this way, monitoring of the paging channel can be done during fewer than all DRX cycles, combating possible collisions between DRX cycles on different radio access technologies, and enabling reduced power consumption. Other aspects, embodiments, and features are also claimed and described.

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: Aspects of the present disclosure relate to a user equipment (UE) and a method of wireless communication using the UE that includes a first transceiver and a second transceiver. The method includes determining that the first transceiver is scheduled to communicate using a first transmission simultaneous to the second transceiver being scheduled to communicate using a second transmission, and altering an operation of at least one of the first and second transceivers to mitigate battery voltage droop due to simultaneous transmissions of the transceivers. Other aspects, embodiments, and features are also claimed and described.

Abstract: Apparatus and methods are disclosed to provide for a multi-SIM wireless user equipment configured for block-level, or slot-level tune-away operations enabling simultaneous communication with a plurality of channels. The first and second channels may correspond to different RANs, each of which the user equipment may subscribe to as corresponding to information in a plurality of SIMs at the user equipment. In other examples, the first and second channels may correspond to different cells within a single RAN. In either case, the tune-away operations disclosed provide for reduced data loss at the first channel and in some examples improved communication performance at the second channel. Other aspects, embodiments, and features are also claimed and described.

Abstract: The present patent application improves DARP by allowing multiple users on one time slot (MUROS). It comprises means and instructions for sharing signals on a single channel, comprising setting up a new connection, allocating a new time slot if there is an unused time slot on a channel frequency, selecting an used time slot for the new connection to share with an existing connection if there is not an unused time slot on the channel frequency, and selecting a different training sequence code for the new connection if the used time slot on the channel frequency has been selected for the new connection to share with an existing connection. Other aspects, embodiments, and features are also claimed and described.

Abstract: The various embodiments include methods for managing how a MSMS communication device that is accessing an arbitrary combination of multiple telephony networks processes paging collisions. The embodiment methods promote improving a subscription's page blocking rate by causing a MSMS communication device to implement a retransmission remedial action for a blocked subscription. In the various embodiments, the MSMS communication device may implement the retransmission remedial action by increasing a blocked subscription's priority during a subsequent retransmission interval to increase the likelihood that the blocked subscription will receive a repeated page message from its mobile network during this retransmission interval. In some embodiments, the blocked subscription's current priority may be based on the number of retransmission intervals that are presently occurring.
