The present invention relates to a method for configuring a retransmission protocol on the uplink between a network node and a relay node in a mobile communication system, the configuration being performed at a network node or at a relay node, and to the corresponding relay node apparatus and network node apparatus capable of configuring the retransmission protocol. In particular, the number of transmission processes is determined based on the position of time intervals available for the transmission and may be selected in order to control the round trip time of the retransmission protocol. Once the number of transmission processes has been configured, the transmission processes are mapped on the available time intervals in a predefined order and repetitively.

The present invention provides an uplink data receiving method and apparatus of wireless transceiver device. The method includes: obtaining a wireless channel state parameter of neighboring wireless transceiver device of the device; obtaining downlink data sent by the neighboring wireless transceiver device in a cross slot with the device; reestablishing an interference signal according to the wireless channel state parameter and the downlink data; and removing the interference signal from an uplink data signal received by the device. By reestablishing the interference signal of the neighboring wireless transceiver device on an uplink data signal received by the device in the cross slot, and removing the interference signal from the uplink data signal received by the device, cross slot interference may be eliminated without influencing the flexible allocation of a dynamic TDD system on wireless resources.

The method comprises: receiving data from a downlink subframe of a first serving cell; and transmitting the data for the ACK/NACK signal from an uplink subframe of a second serving cell; wherein the uplink subframe is determined in accordance with the ACK/NACK timing of the first serving cell, or the ACK/NACK timing of the second serving cell if the data is received from a downlink subframe of the second serving cell, which is identical to the downlink subframe of the first serving cell.

A controller, which is a communication device, includes: a transfer unit including a function of transferring data received from a first terminal to another communication device via wireless communication; and a determination unit configured to determine whether first information is included in the data received by the transfer unit, the first information indicating that the data is to be multicast. The transfer unit is further configured to multicast the data to a second terminal when the determination unit determines that the first information is included. In the data, the second terminal and the first terminal being different terminals.

A method of determining a pair of a target transmission node and a target reception node distributedly and concentratedly using a cooperation header in a multi-hop network performing interference neutralization, is provided. The method of distributedly determining the pair of the transmission node and the reception node includes determining whether any of other reception nodes broadcasts a pair configuration message to configure a pair between a corresponding one of the other reception nodes and the transmission node. The method further includes configuring the pair between the transmission node and the reception node based on the determination.

A technology is described for a time division duplex (TDD) repeater with network protection. The TDD repeater can comprise a first port, a second port, and one or more amplification paths coupled between the first port and the second port. The TDD repeater can comprise a signal detector configured to measure a received signal power for a downlink (DL) signal in a first set of one or more TDD DL subframes. The TDD repeater can be further configured to adjust an uplink (UL) noise power or gain of the one or more amplification paths based on the received signal power for the DL signal in the first set of the one or more TDD DL subframes.
