Abstract:
Provided are a device-to-device (D2D) group communication method and a device using the same. The method includes transmitting a scheduling request for D2D group communication to a base station, receiving first radio resource information for a status report of D2D data to be transmitted from the base station, transmitting a D2D buffer status report to the base station through a first radio resource, receiving second radio resource information including D2D resource allocation information necessary for the D2D group communication from the base station, and transmitting control information for the D2D group communication including a D2D group identifier (ID) as a device ID and D2D user data to two or more communication partner devices belonging to the D2D group.
Abstract:
Methods for flow control in a network are disclosed. In a dual connectivity network environment where a master base station and a secondary base station exist, an operation method of a master base station may comprise transmitting a data frame including a plurality of data packets to a secondary base station; receiving, from the secondary base station, a delivery status frame requesting retransmission of error data packet among the plurality of data packets; and retransmitting the error data packet indicated by the delivery status frame to the secondary base station. Therefore, network performance can be enhanced.
Abstract:
Disclosed are a method for scheduling control information and a method for receiving the scheduled control information in a mobile communication system. The method performed in a base station may comprise performing scheduling on a plurality of transmission time intervals (TTIs) including a first TTI to a Nth TTI which are temporally continuous, wherein N is a natural number larger than 1; and transmitting scheduling information obtained from the scheduling to a first terminal. Thus, power consumption of the terminal can be reduced, and overall system capacity can be increased.
Abstract:
Disclosed are operation methods of a terminal in a wireless communication network. An operation method of a terminal in a communication network may comprise configuring a layer-2 ID of the terminal which is used for device-to-device (D2D) communications for a transmission manner; and performing the D2D communications by using the layer-2 ID. Therefore, performance of the communication network can be enhanced.
