METHODS AND APPARATUSES FOR TRANSMITTING REFERENCE SIGNAL, SETTING REFERENCE SIGNAL TRANSMISSION PATTERN, AND SETTING AND ALLOCATING RESOURCE BLOCK

摘要

A method for transmitting a reference signal, a method for establishing a reference-signal transmission pattern, and a method for establishing a block as well as corresponding apparatuses therewith are disclosed. The reference-signal density is adjusted according to the request degree of the channel estimation performance, and then the reference signal is transmitted to a destination. As a result, the apparatus prevents prevent resources from being unnecessarily wasted, and acquires a high channel estimation performance as necessary, resulting in an increased production yield of a system.
