Abstract: A signaling method for a terminal that performs direct communication between terminals terminal is disclosed. A transmitting terminal transmits a link establishment request message for establishing a link to a receiving terminal, and the receiving terminal transmits a link establishment response message responding to this message to the transmitting terminal. The link establishment request message includes a field indicating a flow to use if the receiving terminal acquires a token.

Abstract: Disclosed are a method and an apparatus for providing low-latency services in a communication system. A downlink communication method may comprise receiving downlink control information (DCI) including resource allocation information from a base station through a control channel of a subframe #n; receiving downlink data from the base station through a data channel of a subframe #n+k indicated by the resource allocation information included in the DCI; and transmitting a first hybrid automatic repeat request (HARQ) response for the downlink data to the base station through a control channel of a subframe #n+k+l. Thus, the performance of the communication system can be improved.

Abstract: An operating method of a slave node that communicates with a master node in an in-band full duplex (IFD) system may comprise receiving a beacon signal from the master node during a training sequence period; transmitting a first self-interference (SI) training sequence including a first radio frequency (RF)/analog SI training sequence, a first automatic gain control (AGC) sequence, and a first digital SI training sequence to the master node during the training sequence period after the beacon signal is received; calculating a filter factor for canceling an analog SI signal input to the slave node on the basis of the first RF/analog SI training sequence; and canceling the analog SI signal from the first AGC sequence on the basis of the filter factor.

Abstract: An operation method of a terminal includes receiving configuration information from a serving base station; measuring channel states of the serving base station and a target base station; when a difference between received signal strengths of the serving base station and the target base station is not less than a handover preparation offset, determining that a handover preparation event has occurred and transmitting a measurement report message to the serving base station; and when the difference is equal to or greater than a handover execution offset, determining that a handover execution event has occurred and transmitting a handover indication message informing of execution of a handover to the target base station. The channel state is normal state, abnormal state, or RLF state, and the configuration information indicates a different handover preparation offset and a different handover execution event according to the channel state.

Abstract: A cooperation MIMO transmitting or receiving method is disclosed. A master terminal calculates a first signal to interference plus noise ratio (SINR), which is SINR between the mater terminal and a base station or between the master terminal and another cluster, and the master terminal calculates a second SINR, which is SINR between a slave terminal and the master terminal. Here, the master terminal forms a cluster with the slave terminal when the second SINR is higher than the first SINR.
