SYSTEM AND METHOD FOR INTRA-CELL FREQUENCY REUSE IN A RELAY NETWORK |
摘要 |
<p>A method for communicating using a wireless communication network is presented. The method may include receiving a channel quality indicator (CQI) from a first UE. The first UE is served by a base station. The CQI characterizes a channel quality between the first UE and the base station when the base station transmits at a high power. A first modulation and coding scheme (MCS) may be determined for when the base station transmits at a low power based on the received CQI. When the spectrum efficiency of the first MCS is equal to or higher than the spectrum efficiency of a pre-determined MCS, first UE may be communicated with using a low power transmission. In some cases, a physical downlink control channel (PDCCH) downlink control information (DCI) message is transmitted to the first UE to identify a power spectral density (PSD) level.</p> |
