Abstract: Techniques described herein include solutions for adaptively handling transport blocks (TBs) based on current memory backpressure conditions. In some aspects, a user equipment (UE) monitors a memory backpressure associated with an application processor of the UE. A baseband processor of the UE may receive a plurality of TBs (e.g., from a base station). Based on the memory backpressure, the UE may choose to only decode TBs having certain prioritized data types, and drop or ignore the remaining TBs. For example, the UE may drop certain low priority TBs destined for the application processor, which alleviates the memory backpressure by allowing the application processor to process piled up TBs causing the memory backpressure. In addition, this frees memory in the baseband processor, allowing the UE to handle high priority TBs used for essential functions (e.g., connection and synchronization with the network) in high memory backpressure scenarios.

Abstract: Methods, systems, and devices for transmitting credits in a downlink (DL) that include detecting adversity associated with the DL, e.g., network congestion, high CPU loads, thermal threshold of components, etc. In response to the adversity, a policy is determined that includes a number of ranked rules, and the policy is enabled. A baseband (BB) receives an indication of a number of available credits that may be received by an Application Processor (AP), and a number of credits equal to the number of available credits is downloaded based on the policy. The policy may include performing a first pass and a second pass of credit distribution to ensure fairness, while maintaining the respective priority levels of applications serviced in the DL.

Abstract: A method for reacquiring a cell after tune-away for an MSMS mobile communication device includes: measuring pilot signal energy of a cell on which a data call was suspended on a first subscription before tune-away; determining whether the measured pilot signal energy is less than a high threshold RSSI value; determining whether a difference between a measured cell timing and a pre-tune-away cell timing is less than a first threshold timing value; determining whether a strongest pilot signal energy received on one of a plurality of rake fingers is greater than a low threshold RSSI value; decreasing the low threshold RSSI value for reacquiring the cell; and in response to determining that the measured RSSI for the strongest pilot signal energy received on one of the plurality of the receiver rake fingers is not less than the decreased minimum threshold RSSI value, reacquiring the cell and resuming the data call.
