System and method for intra-cell frequency reuse in a relay network

摘要

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.

1. A method for communicating using a wireless communication network, the method comprising:
determining a first modulation and coding scheme (MCS) for use in communicating with a first UE served by a base station, the first MCS to be used when the base station transmits at a low power; and when a spectrum efficiency of the first MCS is equal to or higher than a spectrum efficiency of a pre-determined MCS, communicating with the first UE using a low power transmission.
