摘要： A method and a base station are provided. The base station obtains a first path gain of a cellular radio link to a first wireless device, a second path gain of a cellular radio link to a second wireless device and a third path gain of a Device-to-Device radio link between the first wireless device and the second wireless device. When the first, second and third path gains satisfy a threshold condition, the base station instructs the second wireless device to apply network coding on first data transmitted from the first wireless device and to transmit a network coded form of the first data. The base station receives a radio signal with the first data transmitted from the first wireless device and uses the network coded form of the first data transmitted by the second wireless device for decoding the first data.

摘要： Cooperative relaying and network coding to implement diversity in a cellular communications system is disclosed. A primary network node diversity combines a first copy of a first packet overheard by the primary network node with a second copy of the first packet received in a network coded packet from a relay network node to form a combined first packet.

摘要： Techniques are provided for third-party assisted peer-to-peer (P2P) communication. For example, there is provided a method, operable by a network entity, that may involve receiving first information from a first mobile entity, the first information comprising a first message for a second mobile entity. The method may involve receiving second information from the second mobile entity, the second information comprising a second message for the first mobile entity. The method may further involve coding third information based at least in part on the first information and the second information, and sending the third information to the first and second mobile entities. The method may also involve transmitting a control signal that includes processing information for decoding the coded third information to extract the first message or the second message.

摘要： A relay station and a method for relaying signals between a first signal source (S
1 ) and a second signal source (S
2 ) are described. The relay station (R) comprises at least two antennas (ANT
R1 , ANT
R2 ) for receiving/transmitting signals from/to the first and second signal sources (S
1 , S
2 ). At the relay station (R) first and second signals received from the first and second signal sources (S
1 , S
2 ) are network coded thereby generating a first network coded signal and a second network coded signal. The first and second network coded signals are transmitted from the relay station (R) to the first and second signal sources (S
1 , S
2 ) using different antennas (ANT
R1 , ANT
R2 ).

摘要： An overall encoding scheme comprises a first encoding for generating first encoded packets (b 1 , b 2 and b 3 ) from source packets and a second encoding for generating second encoded packets by combination of first encoded packets according to a combination scheme applied by predetermined nodes of the network. The overall encoding scheme is configured by: obtaining (440) a number N of defective paths among paths used to transmit the first and second encoded packets to at least one destination node, a path being defective if an associated quality of transmission is below a predetermined threshold; and selecting (450) the combination scheme from among at least two possible predetermined combination schemes for which a number of encoded second packets is greater than or equal to N.
