Problems solved by technology

[0005] Since the frequency domain resources occupied by user data are dynamically determined according to the size of user data, the selection of modulation and coding methods, etc., if the control information and user data use the same frequency domain resources, the receiving device needs to use all frequency domain resources that may be occupied by the control information. Blind detection is performed on the domain position, which will lead to a very high complexity for the blind detection of the control information by the receiving device

Abstract

The invention discloses a control information sending method, receiving method, device and a storage medium under directly-connected communication scene. The method comprises the steps that a sendingdevice determines a first frequency domain bandwidth occupied by user data to be sent; the sending device selects a second frequency domain bandwidth occupied by the control information correspondingto the user data from candidate frequency domain bandwidth in the number of n (n is integer more than 1); the sending device sends control information to the receiving device based on the second frequency domain bandwidth; the receiving device determines the candidate frequency domain bandwidth in the number of n of the control information sent by the sending device; the receiving device conductsblind detection on the control information based on the candidate frequency domain bandwidth in the number of n. The invention is advantageous in that as the second frequency domain bandwidth occupiedby the control information is selected by the preset candidate frequency domain bandwidth with limited amount, the frequency domain position possibly occupied by the control information can be relatively limited, and the blind-detecting complexity for the receiving device to the control information can be reduced.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a control information sending method, receiving method, device, and storage medium in a direct communication scenario. Background technique [0002] In a V2X (Vehicle to Everything, Internet of Vehicles) technology, a vehicle-mounted device can communicate with other devices (such as other vehicle-mounted devices, roadside infrastructure, etc.) through a direct link (sidelink). For the direct connection communication scenario in V2X technology, it is necessary to provide higher communication rate, shorter communication delay, and more reliable communication quality to meet more business needs. [0003] For the direct connection communication scenario in V2X technology, how the sending device sends control information and user data to the receiving device is a problem to be studied and solved. Before sending user data to the receiving device, ...
