Abstract: Example communication methods and devices are described to reduce possibility that account information of a contact corresponding to an electronic business card is leaked. One example method includes receiving a first electronic business card sent by a second terminal. The first electronic business card is an electronic business card of a user corresponding to a client of a third terminal or a client of the second terminal. A first identifier used to identify an account of a user corresponding to the first electronic business card is displayed based on the first electronic business card. Displaying the first user account is skipped.

Abstract: Embodiments provide a data exchange method, a terminal device, and a network device. In accordance with the disclosure, a terminal device can obtain resource information for communicating with another terminal device. The resource information can indicate a time-frequency resource and an antenna port corresponding to an antenna polarization direction. The terminal device can then send scheduling information and data information to the another terminal device using the time-frequency resource and the antenna polarization direction. Time-frequency resources and/or antenna polarization directions used by any two terminal devices to send scheduling information and data information to other terminal devices can be different. In this way, terminal devices using different transmit antenna ports can use a same time-frequency resource, and an optional dimension of resource information is increased, thereby increasing an overall system communication capacity.
