Abstract: A method for mapping a physical hybrid automatic repeat request indicator channel (PHICH) is described. The method for mapping a PHICH includes determining an index of a resource element group transmitting a repetitive pattern of the PHICH, according to a ratio of the number of available resource element groups in a symbol in which the PHICH is transmitted and the number of available resource element groups in a first or second OFDM symbol, and mapping the PHICH to the symbol according to the determined index. In transmitting the PHICH, since efficient mapping is performed considering available resource elements varying with OFDM symbols, repetition of the PHICH does not generate interference between neighbor cell IDs and performance is improved.

Abstract: In an automation network comprising a plurality of network segments, fragmenting subscribers that support a fragmentation method as well as standard subscribers that do not support the fragmentation method can be provided for in the network. A distribution node in the automation network has at least one input/output interface that is in communication with a network segment. The switching unit in the distribution node checks whether a subscriber in a network segment to which a telegram is to be sent supports the fragmentation method, and whether the telegram to be sent is fragmented. If the subscriber does not support the fragmentation procedure and the telegram to be sent is fragmented, the switching unit in the distribution node assembles the telegram fragments to form the telegram and then sends the assembled telegram on to the subscriber.

The batch size is indicative of a threshold number of queued packets required to be present in the queue before the queued packets in the queue can be processed by the network device.
