PRE-CODING

摘要

A pre-coding adaptation process includes one or more pre-coded reference signal exchange between an apparatus using a first resource type for a first pre-coded reference signal and a user device using a second resource type for a second pre-coded reference signal. For example, if the link direction is up-link, the first resource type may be a backward phase and the second resource type is a forward phase, and if the link direction is downlink, the first resource type may be a forward phase and the second resource type is a backward phase.
