Title:
INFORMATION SENDING METHOD AND RECEIVING METHOD, INFORMATION SENDING APPARATUS AND RECEIVING APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/093326
Kind Code:
A1
Abstract:
The present disclosure relates to an information sending method and receiving method, an information sending apparatus and receiving apparatus, and a storage medium in a sidelink communication scenario. The information sending method comprises: a sending device determining a first frequency domain bandwidth occupied by control information to be sent, and a second frequency domain bandwidth occupied by user data corresponding to said control information; the sending device occupying m different frequency domain resources in a frequency division multiplexing manner to repeatedly transmit the control information m times to a receiving device; and the sending device occupying target frequency domain resources to send the user data to the receiving device. In the technical solution provided by the present disclosure, a sending device occupies a plurality of different frequency domain resources and repeatedly transmits control information to a receiving device in a frequency division multiplexing manner; thus, compared with the sending device transmitting control information only once, the probability of detecting the control information is correspondingly improved when the receiving device performs blind detection of the control information, thereby reducing the complexity of blind detection of the control information by the receiving device.
