20110199985 | SYSTEM AND METHOD FOR INTRA-CELL FREQUENCY REUSE IN A RELAY NETWORK - 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. | 08-18-2011 |

20130265966 | Supplemental Node Transmission Assistance in a Wireless Network - Supplemental node transmission assistance in a wireless network provides for transmissions between a wireless network and wireless user equipment in a first direction using a serving node of the wireless network while providing for transmissions between the wireless network and wireless user equipment in a second direction using a supplemental node of the wireless network. The supplemental node is selected based on providing better channel conditions between the network and the user equipment in the second direction than the serving node. The supplemental node thus provides transmission assistance for the serving node in order to provide the best available downlink and uplink communications between the user equipment and the network. | 10-10-2013 |
