Abstract

The present invention relates to wireless communication devices and methods using reference signals. The method may include obtaining a plurality of pilot rules and obtaining radio channel information of a radio channel between the wireless communication apparatus and another wireless communication apparatus in an area. The area includes at least one cell and uses one or more data streams. Further, the method may include selecting applicable pilot rules from the plurality of pilot rules based on the radio channel information, creating at least one pilot structure to be used in the radio channel; and using the created at least one pilot structure to transmit data over the radio channel.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a wireless communication technology using a reference signal. Background technique [0002] In the field of next-generation wireless communication systems, the latest research and development aims to provide higher data transmission rates than existing systems. In order for wireless devices and systems to communicate at much higher data rates, better mechanisms are needed to perform initial clock and frequency synchronization, cell authentication, and channel estimation. Generally, reference signal or pilot signal symbols etc. are used to provide these mechanisms. [0003] A reference signal or pilot symbol refers to a known signal sequence inserted at a known location (clock or frequency) of a data stream, which allows the communication device to easily detect, and allows the communication device to perform clock and frequency Synchronization to measure channel inform...
