摘要： A physical layer frequency translating repeater (600, 700) for use in a wireless network includes signal processor (710-714) coupled with a signal processing bus (711), a processor (627) and a memory (650). The physical layer repeater conducts physical layer repeating and selectively conducts layer 2 and possibly layer 3 functions depending on network conditions and other factors. A demodulator (623) can extract address information such as media access control (MAC) addressing to enable packets to be redirected, terminated, stored and forwarded, if necessary, based on network conditions.

摘要： A communication apparatus communicates with a receiving apparatus which receives, combines and decodes first and second data sections as part of a coded data block. The communication apparatus includes a controller that controls the ratio of how much part of the second data section overlaps with the first data section according to a difference of communication quality between a first resource used to transmit the first data section and a second resource used to transmit the second data section.

摘要： Providing for soft error decoding for wireless relay networks is described herein. By way of example, a wireless node in a wireless relay network can receive a direct signal from a source node, and can receive a forwarded version of the source signal from a relay node. An information flag included with the forwarded version is referenced to determine whether the relay node property received the source signal. If the relay node received the source signal with error, and a destination node received the source signal with error, soft decision information can be generated from the forwarded version of the source signal and employed to assist with decoding of the source signal at the destination node. The soft-decision information improves end-to-end performance of the wireless relay system, while mitigating complexity and bandwidth requirements for the relay node as compared with conventional signal decoding techniques.

摘要： The present invention relates to a method and a network coding node for resource allocation applicable to multi-directional network coding in an exchanging system. By estimating the number of bits per resource element (steps 402, 404) on uplink channels to a network coding node (200, 304, 504, 604), the number of resource elements for the sending on said uplinks is determined (step 410) to fully utilize the resources, i.e. such that link underutilization is avoided as well as incorporation of delays are avoided. The number of resource elements is decided such that the data transmitted to the network coding node is provided to end-nodes (302, 306, 502, 506, 602, 606) by sending one and the same representation of the data from a first and a second end-node, to said first and second end-nodes enabling extracting data originated from the differing end-node.

摘要： The present invention relates to a method for selective relaying in a communication network including a plurality of sources, a relay, and a recipient, characterized in that the method comprises the following steps: receiving, via the relay, messages transmitted by the sources, respectively, so as to obtain an estimate of the messages; detecting, at the relay, errors on the estimated messages; and transmitting, from the relay to the recipient, a signal representative of single messages for which no error has been detected resulting from a non-bijective surjective function applied to the detected error-free messages including interleaving and encoding. The representative signal is transmitted by the relay to the recipient with a control signal indicating which messages are represented in the representative signal. The present invention also relates to a device for selective relaying in a communication network.

摘要： A method for enabling simultaneous data transmissions in a wireless network includes broadcasting a first signal from a first node, receiving the first signal by a second node, and transmitting a second signal derived from the first signal by the second node. The second signal is received by the first node. A third signal is transmitted from a third node to the first node simultaneous with transmitting the second signal. The first node receives a combination signal which includes the second signal and the third signal. The first node then decodes the third signal from the combination signal using the first signal.

摘要： A wireless relay station apparatus for enabling a mobile station and a base station to reliably receive network coding data and to provide sufficient reception performance is provided. (1) A repeater divides data X received from a mobile station into important data and non-important data and divides data Y received from eNB into important data and non-important data. Next, (2) the repeater places the data so that important data Sx for the mobile station and important data Sy for the eNB do not overlap, XORs (exclusive ORs) them, and generates network coding data X (X) Y. (3) The repeater applies downlink propagation inverse characteristic H1 -1 to important data portion Px (X) Sy for the mobile station and on the other hand, applies uplink propagation inverse characteristic H0 -1 to important data portion Sx (X) Py for the eNB in the network coding data X (X) Y for transmission.
