Document Type and Number:
WIPO Patent Application WO/2019/158002
Kind Code:
A1
Abstract:
Provided are a transmission method and a communication device. The method comprises: using, in a first time period, a transmit diversity scheme to transmit first control information; and using, in a second time period, a single antenna scheme to transmit second control information, wherein resources indicated in the first control information and the second control information are fully identical or partially identical, and there is a time interval between the first time period and the second time period. In the transmission method provided in an embodiment of the present invention, using different transmission schemes in a process of transmitting control information facilitates improving reception performance of communication devices having different relative speeds, thereby preventing deterioration of reception performance resulting from use of only one transmission scheme.
