Flexible redundancy using RF switch matrix
Techniques including controlling coupling and uncoupling of RF ports included in an RF switch matrix including first-side RF ports and second-side RF ports, where each of the first-side RF ports is configured to be selectively coupled to at least one of two or more of the second-side RF ports, identifying one or more of the second-side RF ports as active ports including an active port, causing the RF switch matrix to couple the active port to a signal port included in the first-side RF ports, obtaining at least one of a bit error rate and a signal to noise ratio for a demodulation of an RF stream received via the active port, and causing, in response to at least one of the bit error rate or the signal to noise ratio, the RF switch matrix to couple the signal port to a spare port included in the second-side RF ports.

Method and apparatus for controlling packet transmission
The purpose of the present invention is to provide a method for increasing data transmission efficiency when performing packet duplication. A method for a terminal in a wireless communication system according to the present invention comprises the steps of: performing protocol data convergence protocol (PDCP) duplication in which an identical PDCP protocol data unit (PDU) is transmitted to a base station through each of a first logical channel and a second logical channel; when a request for retransmission of the PDCP PDU which has been transmitted through the second logical channel is received from the base station, retransmitting the PDCP PDU to the base station; and when the PDCP PDU has been retransmitted a predetermined number of times or more, receiving, from the base station, information indicating deactivation of the PDCP duplication.

Method and system for the error-correcting transmission of a data record via a unidirectional communication unit
A method and a system for fault-correcting transfer of a dataset from a first network into a second network via a unidirectional communication unit, the receiving apparatus having a limited computing and main memory capacity is provided. The dataset is divided into partial datasets and are each coded by adding at least one correction mark. The marks and correction marks are decoded repeatedly in the second network, wherein marks and correction marks associated with a first encoded partial dataset are stored in a main memory, marks and correction marks associated with other encoded partial datasets are buffered in a background memory, and the first coded partial dataset is decoded, and then the previously received marks and/or correction marks of one of the other coded partial datasets are shifted from the background memory into the main memory. The dataset is reproduced from the decoded partial datasets in the second network.
