Apparatus, methods, and computer-readable media for facilitating prioritizing PDCP retransmission and/or control information in dual connectivity scenarios are disclosed herein. An example method for wireless communication at a first network node includes receiving PDUs for transmitting to a second network node while operating in a dual connectivity mode associated with a first RLC leg and at least a second RLC leg, the PDUs associated with at least one of control information or retransmission data. The example method also includes transmitting first scheduling information via the first RLC leg and transmitting second scheduling information via the second RLC leg based on the PDUs being associated with at least one of the control information or the retransmission data. The example first network node may include a UE or a base station.

Techniques to facilitate prioritizing packet data convergence protocol (PDCP) protocol data units in dual connectivity

Methods and devices may select a particular radio access technology (RATs) available on a multi-technology wireless communication device to support a user activity based on monitored device usage patterns and power consumption profiles of the various RATs. Various embodiments may enable multi-RAT wireless communication devices to monitor the usage patterns of each service (i.e., wireless communication link) provided by the device, and estimate the power consumption during the user activity based on the power needs of services and the user activity. A multi-RAT wireless communication device may determine whether switching, enabling, or disabling services and/or RATs would reduce power consumption. Thus, the wireless communication device may extend the time that a user can perform a user activity when battery reserves are low by switching to a lower-power RAT and/or disabling power-hungry services.

Power management in multi-technology wireless communication devices

Methods and devices are disclosed for enabling efficient network registration using a shared radio resource for at least a first and second SIM of a multi-SIM wireless communication device. An overall priority-based ranking may be calculated for each SIM of the multi-SIM device, which may be used to determine an preferred order for the SIMs to register for services in their respective networks. Calculating the overall priority-based ranking for each SIM may include determining values for a service capability priority factor, an attachment time factor, and a sleep cycle duration factor.

System and methods for improving network registration for all SIMs of a multi-SIM device using a dynamically-determined registration order

Methods and devices are disclosed for enabling efficient network registration using a shared radio resource for at least a first and second SIM of a multi-SIM wireless communication device. After the end of a radio-off condition of the radio resource, the wireless device may identify services supported by each of the first and second SIMs, evaluate criticality of the supported services, determine which of the first and second SIM supports the service having the highest criticality, and prevent the other SIM from registering with its network before the SIM with the service of the highest criticality has successfully registered for service in its selected network.
