Title:
RADIO RESOURCE ALLOCATION METHOD AND APPARATUS FOR DEVICE TO DEVICE COMMUNICATION IN MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/105387
Kind Code:
A1
Abstract:
A method for supporting a device to device (D2D) communication in a base station of a mobile communication system according to one embodiment of the present specification comprises the steps of: determining one or more device groups including one or more devices among a plurality of devices; determining radio resources for measuring channels for the determined device groups; and transmitting, to the devices included in the respective groups, information on the radio resources for measuring the channels corresponding to the groups. According to the embodiment of the present specification, complexity of measuring a channel state in the D2D communication is reduced, and many more devices can measure the channel state using limited radio resources and can transmit and receive data.
