COMMUNICATION METHOD, COMMUNICATION APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/191970
Kind Code:
A1
Abstract:
Provided is a communication method. The communication method is carried out in a communication system comprising a network device and a terminal device, wherein the terminal device is configured with N antenna ports, N being an integer greater than or equal to 2; the N antenna ports correspond to T antenna port combination modes; each of the antenna port combination modes corresponds to M antenna ports of the N antenna ports; and each set of antenna port combination modes comprises at least one antenna port combination mode. The network device receives first indication information from the terminal device, wherein the first indication information is used for indicating a first set of antenna port combination modes; and the network device determines, according to the first set of antenna port combination modes, K antenna ports from the N antenna ports; and the network device sends second indication information to the terminal device, wherein the second indication information is used for indicating the K antenna ports. By means of the communication method of the embodiments of the present application, an antenna port can be dynamically chosen from multiple antenna ports of a terminal device for uplink signal transmission. The method provided in the embodiment can be applied to a communication system, such as V2X, LTE-V, V2V, an Internet of vehicles, MTC, IoT, LTE-M, Μ2Μ and an Internet of things.
