Abstract: Access terminals are adapted to facilitate optimized tune-away operations in multi-subscription wireless communication devices. According to one example, an access terminal can communicate on a first subscription. After a period of time, the access terminal can tune away from the first subscription to a second subscription to perform a communication activity corresponding to the second subscription. After tuning back to the first subscription, the access terminal may transmit uplink data while ignoring any absolute grant received after tuning back to the first subscription, and/or transmit a scheduling information message in response to tuning back to the first subscription from the second subscription. Other aspects, embodiments, and features are also included.

Abstract: Access terminals capable of employing multiple subscriptions are adapted to prevent out-of-service periods for one or more subscriptions. According to one example, an access terminal can establish a data communication on a first subscription utilizing a first network, and an idle mode connection on a second subscription utilizing a second network. A determination can be made that the first subscription is indicating data transfer. In response to such a determination, the second subscription can attempt a change from a radio access technology associated with the second network to a different radio access technology. Other aspects, embodiments, and features are also included.

Abstract: Apparatus and methods are disclosed for a multi-SIM/multi-standby wireless user equipment (UE) configured for tune-away operations enabling simultaneous communication on multiple subscriptions using a shared RF chain while maintaining an ongoing signaling procedure on a primary subscription. The UE performs a signaling procedure with a first network associated with a first subscription, and decodes a downlink channel of the first network during an initial period of a transmission time interval (TTI). If the decoded downlink channel indicates that no data of the first subscription is destined to the UE during the current TTI, the UE tunes away to a second subscription to receive data from a second network associated with the second subscription.

Abstract: The disclosure provides for a UE handling messages in wireless communication. The disclosure provides for a UE partially exchanging a first signaling-related message associated with a first UE configuration with a network entity and triggering a state transition message that initiates a change to a second UE configuration different from the first UE configuration. In an aspect, the UE determines that the first message has not been successfully received or successfully transmitted. In an aspect, the UE sends an indication message to coordinate discarding of the first message with the network entity and receives, after sending the indication message, a second signaling-related message associated with the second UE configuration. In another aspect, the UE, after partially sending a signaling-related message, receives a reconfiguration request associated with a second UE configuration. In an aspect, the UE determines that the message has not been successfully transmitted and causes a reconfiguration failure.

Abstract: Aspects of the disclosure provide for a method of efficiently implementing security configurations for multiple domains between a network entity and a UE in a wireless system. For instance, this disclosure provides for a network entity sending to a UE a first security mode command for a first domain, receiving a first security mode complete message in response to the first security mode command, and sending a second security mode command for a second domain. In an aspect, the second security mode command is sent in response to receiving the first security mode complete message. In an aspect, the UE does not receive a RLC acknowledgement. In another aspect, the UE saves the second security mode command until it receives the RLC acknowledgement. In an aspect, the network entity sends the second security mode command in response to receiving a message protected with first security procedure parameters.

Abstract: In aspects for controlling transmit power of dual carrier uplink transmission for wireless communications, a user equipment (UE) determines presence of transmit power imbalance between a first and second radio frequency (RF) carrier of respective dedicated physical control channels for uplink transmission. The UE determines an estimate of a remaining available transmit power after estimating the transmit power used by each of the dedicated physical control channels. The UE allocates the estimated remaining available transmit power to the first and second RF carrier respectively based on both a size of data granted for uplink transmission on each RF carrier and on an effective power per bit on each RF carrier. Additionally, the UE determines a higher reliability value for each RF carrier based on a lower data error rate, identifies priority values for data to be transmitted and sends higher priority data over the RF carrier with higher reliability value.
