[0054] The technical solution of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0055] A method for processing control information transmission from a base station to a relay node provided by the present invention, such as figure 1 As shown, it mainly includes the following steps:
[0056] Step 101: The eNodeB carries its control information to the RN through at least one of resource block bearing, OFDM symbol bearing and frequency resource bearing.
[0057] Such as figure 2 As shown, the so-called resource block refers to occupying several subcarriers (for example, 12 subcarriers) in the frequency direction, and occupying all OFDM symbols in a slot or subframe in the time direction; the so-called frequency resource refers to the concentration of OFDM symbols. Several sub-carriers ( figure 2 Shown in both shades). The frequency resource bearing in the present invention includes: a centralized frequency r...
