A method of wireless communication performed by a user equipment (UE) includes: operating in a Dual SIM Dual Standby (DSDS) mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS); transmitting a sounding reference signal (SRS) from a communication port of the UE, wherein the SRS has a timing offset assigned by a network associated with the first SIM; receiving paging messages from a network associated with a second SIM; determining an offset adjustment to avoid a collision between the SRS and the paging messages; sending a request to the network associated with the first SIM to adjust the timing offset according to the offset adjustment; and receiving an offset change configuration from the network associated with the first SIM.

Disclosed are techniques for handling collisions between multiple radio resource control (RRC) connection establishment procedures for multiple connection events, such as mobile terminating pages and tracking area updates.

Handling collisions due to multiple radio resource control (RRC) connection requests

In an embodiment, a client device receives a set of network registration credentials configured to authorize access to one or more network services provided by a network server. The client device shares the set of network registration credentials with an external device (e.g., a peer client device or an access point) via D2D. In another embodiment, a device (e.g., the external device or a different device) receives the set of network registration credentials via D2D and interacts with the network server to access a network service using the set of network registration credentials. In another embodiment, the device shares the set of network registration credentials with another client device via D2D.

A wireless communication device having a first SIM and a second SIM and a radio frequency (RF) resource including multiple receive chains and at least one transmit chain may detect, during a connection to a first network associated with the first SIM, a start of a communication activity associated with the second SIM that uses one or more transmit chains and one or more of the receive chains. The wireless communication device may determine whether a carrier frequency of a cell serving the network associated with the first SIM is within a downlink frequency range supported by an unused receive chain of the RF resource. If not, the wireless communication device may identify a neighbor cell of the first network with a carrier frequency within a downlink frequency range supported by an unused receive chain of the RF resource, and attempt to camp the first SIM on that neighbor cell.

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine, when involved in a multimedia broadcast or multicast service, a set of parameters relating to the state of the wireless communication device. In some aspects, the wireless communication device may determine to decode a signal associated with the multimedia broadcast or multicast service during a measurement gap based at least in part on the set of parameters. In some aspects, the measurement gap may be a gap configured for performing an intra-radio access technology (IRAT) or inter-frequency cell measurement.

The various embodiments provide methods for implementing a forced reselection strategy after causing colliding subscriptions to perform reselection to neighboring cells. In various embodiments, the MSMS communication device may undo the effects of forced reselection in certain situations when continuing to employ forced reselection may be ineffective. In other embodiments, the MSMS communication device may force reselecting subscriptions to reselect to neighboring cells in a paging group based on the page timings of the neighboring cells. Thus, the various embodiments may increase the performance of the colliding subscriptions and may enhance the user's overall experience.

Methods and apparatus for wireless communication in mobile device that includes operating communication resources according to a first subscription to establish an active call at a certain transmit power. Aspects of the methods and apparatus include tuning away the communication resources to operate according to a second subscription. Aspects of the methods and apparatus include tuning back the communication resources to the first subscription from the second subscription. Aspects of the methods and apparatus also include calculating an adjusted transmit power for the first subscription and operating the first subscription on the adjusted transmit power.

Methods, systems, and devices are described for system acquisition at a mobile device. A scan list including a plurality of entries may be stored at the mobile device. Each entry may include at least one connection parameter for connecting to a cellular system associated with the entry. A connection may be established with a target cellular system at the mobile device. A connection time with the target cellular system may be measured at the mobile device. A time-based entry including at least one connection parameter for the target cellular system may be added to the scan list based at least in part on the measured connection time with the target cellular system. Other aspects, embodiments, and features are also claimed and described.
