1. carry out order across the repeatedly transmission in a transmission frame and walk a method of falling to keep code check, comprising:

  • Generate multiple code elements of having encoded at access point place;

    According to the feedback from accessing terminal or to reflect that order walks the certainty mode of falling and upgrades MIMO transmission rank M;

    To determine the value M of each MIMO layer, wherein M is an integer point by described code element of having encoded;

    AndUtilize a spatial mappings matrix to carry out spatial mappings M layer.
