Resource allocation and UE behavior for D2D synchronization signal transmission for cross-cell inter-device (D2D) detection

摘要

Techniques for improving resource allocation for cross-cell device-to-cell (D2D) detection and timing synchronization between user equipments (UEs) connected to an asynchronous network configuration are disclosed. In addition, transmission rules are provided for the network, and a storage area for sharing the detection resources is allocated by a frequency division multiplexing (FDM) method. In the first subframe of the transmission resource sharing storage area, there may be an overlap between the resources allocated for the detection resource sharing storage area and the resources allocated for the D2D synchronization signal (D2DSS). Good. Non-overlapping PRBs in the detection resource sharing storage area can also be allocated for WAN transmission or D2D detection transmission. In a situation where the detection resource sharing storage area is allocated using FDM, for example, a measurement result such as reference signal received power (RSRP) or path loss may be generated for the UE. The measurement result may be compared with a threshold for determining whether or not the UE transmits D2DSS.
