Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple transport blocks (TBs) representing an application data unit (ADU) from a base station. The base station may transmit an indication that the UE is to provide ADU level feedback. The UE may determine the ADU level feedback based on whether the ADU is successfully received and decoded or not. The UE may indicate the ADU level feedback for the TBs to the base station. The base station and the UE may communicate according to the ADU level feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE has received, from a network, a sufficient quantity of protocol data units (PDUs) to decode a frame. Accordingly, the UE may indicate, to the network, that the UE has decoded the frame. Similarly, the UE may determine that the network has received, from the UE, a sufficient quantity of PDUs to decode a frame. Accordingly, the UE may refrain from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the UE may receive, from the network, an indication to disable some feedback to the network. Accordingly, the UE may refrain from transmitting one or more feedback signals based at least in part on the indication. Numerous other aspects are described.

Abstract: Redundancy information is added to information to be sent over a medium and sent as spatially coupled chain with the redundancy information as local decision verification codes. In the receiving end, when the local decision verification code has been satisfied a preset number of times, a sliding window is shifted.

Abstract: The present invention improves communication systems by providing a virtual binary erasure channel over a frame-based data exchange infrastructure, through a combination of time diversity mechanisms with bit-based interleaving agents. The interleaving agents are judiciously positioned in the data processing path to provide benefits to the forward error correction functions of the communication system. The invention thus allows for a significant reduction of the complexity of the error correction facilities of a communication system such as a DVB-SH system, by allowing the efficient use of a low-complexity binary based decoder.
