Ｖ２Ｘ送信のための改良された無線リソース選択およびセンシング

Document Type and Number:

Japanese Patent JP6990749

Kind Code:

B2

Abstract:

To provide an improved UE-autonomous radio resource allocation procedure for data transmission via a sidelink interface.SOLUTION: A procedure by a transmitting device comprises performing a resource sensing procedure to acquire information about usable radio resources and, after data becomes available for transmission, the transmitting device performs an autonomous radio resource allocation to select radio resources within a transmission window to be used for transmitting the data, based on the information acquired through the resource sensing procedure. The autonomous radio resource allocation comprises selecting radio resources in primary subframes of the transmission window preferably over radio resources in secondary subframes of the transmission window. The secondary subframes correspond to those subframes during which the transmitting device did not perform the resource sensing procedure in the period of a sensing window, and the primary subframes correspond to those subframes during which the transmitting device did perform the resource sensing procedure.SELECTED DRAWING: Figure 11
