High-speed tune-away for multi-SIM devices

摘要

A user equipment (UE) prevents re-transmissions of downlink high-speed data during a tune away procedure when an acknowledgment (ACK) to the high-speed data is not received at a network. In one instance, the UE decodes a first high-speed grant and corresponding downlink high-speed data before tuning away from a serving base station. The UE determines that a first timing for transmitting an acknowledgement of the decoded high-speed downlink data occurs during a tune away gap. The UE determines a second time for sending the acknowledgment based on a determination of a second high-speed grant missed during the tune away gap. The UE transmits an acknowledgement (ACK) for the decoded downlink high-speed data in accordance with a time line of the missed second high-speed grant.

1. A method of wireless communication, comprising:
decoding a first high-speed grant and corresponding downlink high-speed data before tuning away from a serving base station; determining that a first time for transmitting an acknowledgement of the decoded downlink high-speed data occurs during a tune away gap; determining a second time for sending the acknowledgment based at least in part on a determination of a second high-speed grant missed during the tune away gap; and transmitting an acknowledgement (ACK) for the decoded downlink high-speed data in accordance with a time line of the missed second high-speed grant.
