摘要： 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.

摘要： In general, according to an embodiment, a wireless transmitter includes a plurality of coding and modulation modules to apply corresponding coding and modulation algorithms to input information blocks. A discrete Fourier transform (DFT) precoder applies DFT processing to outputs of the coding and modulation modules, and an inverse fast Fourier transform (IFFT) module receives a DFT output of the DFT precoder, which is mapped to different subcarriers according to the resource allocation indicated by the base station, and applies IFFT processing to the DFT output. An output processing stage produces output signals based on the output of the IFFT module to transmit wirelessly to a wireless receiver. In a different implementation, the outputs of the coding and modulation modules can be provided to an IFFT module to produce IFFT-processed output information.
