Patent number: 11096241Abstract: The layer processing includes at least processing on a first, a second and a third layer. At the transmitter side, the third layer receives a packet, adds its header and forwards the packet to the second layer. The second layer performs segmentation and provides segmented data to the first layer, which maps the segmented data onto physical resources. The segmentation is based on the allocated resources. Retransmissions may take place on the third layer and thus, the third layer may re-segment the packet according to the received feedback for particular segments and provide the re-segmented data to the lower layers. Alternatively, the feedback information is provided to the second layer which then performs the segmentation by taking it into account. Correspondingly, the receiver performs re-ordering and re-assembly at the third layer for which it receives also control information from the second layer.Type: GrantFiled: February 4, 2019Date of Patent: August 17, 2021Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Rikin Shah, Joachim Loehr, Prateek Basu Mallick, Takako Hori
