Certain aspects of the present disclosure provide techniques and apparatus for quick radio link control (RLC) retransmission on hybrid automatic repeat request (HARQ) failure during tune away. According to certain aspects, a method for wireless communications is provided. The method generally includes performing communications with a base station (BS) using radio components tuned to a first air interface, detecting a tune-away of the radio components from the first air interface to a second air interface while performing the communications, and scheduling one or more packets for retransmission to the BS upon completion of the tune-away, wherein the one or more packets are one or more packets that failed to be transmitted due to the tune-away.

Quick RLC retransmission on HARQ failure during tune away

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines a failure to receive an MSI for a first MSP. The UE attempts to decode one or more subframes in the first MSP. The UE detects an occurrence of an MSP abort decoding event. The UE determines that the first MSP does not include any subframe that carries MBMS data of an MBMS segment based on the detection of the MSP abort decoding events. The UE aborts the attempt to decode the one or more subframes.

Abort blind MCH decoding

Aspects of the present disclosure relate to wireless communication devices and methods configured to operate with multiple communication protocols in tune-away operations. Some aspects of the present disclosure may improve the legacy tune-away operations at an access terminal. An access terminal establishes a call utilizing a first communication protocol, tunes away from the call to receive cell signaling utilizing a second communication protocol, and tunes back to the call utilizing the first communication protocol. Following the tuning back, during a first predetermined number of subframes and if the size of a reverse link (RL) packet is smaller than a first packet size and larger than a second packet size, the access terminal forces the RL packet to be a low latency (LoLat) packet.
