Abstract: The present disclosure relates to an apparatus and method supportive of distributed turbo coding based on relay network utilizing a noisy network coding scheme. For this, included is a relay node operating as a component encoder to relay a signal from a source node to a next node in a distributed turbo coding scheme. The relay node quantizes the signal transmitted from the source node and then interleaves the quantized signal using a predetermined pattern to distinguish the signal transmitted from the source node from a signal to be output from an opposing node, so that the signal transmitted from the source node is relayed to the next node based on a noisy network coding scheme.
Abstract translation: 本公开涉及一种利用噪声网络编码方案的基于中继网络的支持分布式turbo编码的装置和方法。 为此，包括作为分量编码器操作的中继节点，以在分布式turbo编码方案中将来自源节点的信号中继到下一个节点。 中继节点对从源节点发送的信号进行量化，然后使用预定模式对量化信号进行交织，以将从源节点发送的信号与从相对节点输出的信号区分开，从而从源节点 基于嘈杂的网络编码方案中继到下一个节点。

Abstract: Disclosed is a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as LTE. A method for cancelling self-interference in a full-duplex communication system is provided. The method comprises the steps of: cancelling cancellable self-interference components through an analog interference cancellation circuit, and estimating a channel state of an uplink channel and a channel state of a downlink channel on the basis of remaining residual self-interference components; estimating a channel capacity for each of possible beam combinations on the basis of the estimated uplink channel state and downlink channel state; selecting the beam combination having the largest channel capacity from among the possible beam combinations; and cancelling self-interference from a received signal on the basis of the selected beam combination.

Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for performing a beamforming operation in a wireless communication system supporting a full-duplex scheme includes acquiring reference information for allocating a resource, determining a user equipment (UE) combination of a transmission (Tx) UE and a reception (Rx) UE which is capable of sharing a resource from combinations of at least Tx UE and at least one Rx UE, based on the acquired reference information, and allocating a Tx antenna beam for the Tx UE of the UE combination and an Rx antenna beam for the Rx UE of the UE combination.

Abstract: The present invention relates to a 5th-generation (5G) or pre-5G communication system provided for supporting higher data transmission rates than 4th-generation (4G) communication system such as long term evolution (LTE). The present invention relates to a method in which an access point (AP) operates a full-duplex scheme in a communication system supporting a beam-forming scheme, the method comprising the steps of: generating a magnetic interference intensity table according to transmitted beam patterns and received beam patterns; determining, by the AP, a transmitted beam pattern and a received beam pattern for all stations (STAs) on the basis of channel measurement feedback information received from the stations, which provide service, and the electromagnetic-interference intensity table; and performing a communication operation with each of the stations on the basis of the determined transmitted beam pattern and received beam pattern.

Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for cancelling a self-interference (SI) signal in a communication system supporting a full-duplex scheme is provided. The method includes estimating an SI channel, performing a pre-filtering operation on a transmission signal based on the estimated SI channel, generating copied-SI signals based on the estimated SI channel, and cancelling an SI signal based on the copied-SI signals, wherein the pre-filtering operation includes an operation for decreasing a number of SI signals.
