System and Methods for Improving Data Performance Via Deliberate Hybrid Automatic Repeat Request (HARQ) Acknowledgment (ACK) and Fast Radio Link Control (RLC) Non-acknowledgment (NACK) in a Multi-Subscriber Identity Module (SIM) Wireless Communication Device

摘要

Methods and devices are disclosed for managing diversity tune-away on a wireless communication device configured with at least two radio frequency (RF) receive resources associated with a connection in a high speed data network. The wireless device may monitor data communications and downlink channel conditions in the high speed data network, and determine whether a diversity tune-away mode has been entered. Upon determining that the diversity tune-away mode has been entered, the wireless device may perform a deliberate acknowledgment procedure by ignoring normal error detection for received data and sending an acknowledgment message for the received data to the high speed data network. The wireless device may determine whether the diversity tune-away mode has ended, and in response to determining that the diversity tune-away mode has ended, and halt the deliberate acknowledgment procedure in response to determining that the diversity tune-away mode has ended.

主权项

1. A method of managing downlink data throughput in a wireless communication device having at least one radio frequency (RF) resource configured with at least a first and second receive chain that are both associated with a connection in a data network, the method comprising:
determining whether a diversity tune-away mode is entered; performing a deliberate acknowledgment procedure in response to determining that the diversity tune-away mode is entered, wherein performing the deliberate acknowledgment procedure comprises:
ignoring normal error detection for data received in a communication and sending an acknowledgment message for received data to the data network; anddetermining whether the diversity tune-away mode has ended on the wireless communication device; and halting the deliberate acknowledgment procedure and resuming normal error detection for the received data in response to determining that the diversity tune-away mode has ended.
