Abstract
One or more radio characteristics are considered to determine selection of one or more of the following: interleaving scheme, channel coding scheme, modulation scheme, and/or transmission scheme. Accounting for these factors and interdependencies improves performance in a mobile radio communications system. One example performance measure is throughput over the radio interface.
Claims45
A method for communicating blocks of data over a radio interface using multiple antennas, each antenna being associated with at least one corresponding radio channel and each data block including multiple data units, comprising:
- determining one or more characteristics of the radio channels associated with the multiple antennas;
- determining one or more diversity conditions of the radio channels based on one or more of the radio channel characteristics;
- based on the determined one or more radio channel characteristics, selecting one of plural channel coding schemes to code a data block;
- coding the data block using the selected channel coding scheme;
- based on the determined one or more diversity conditions, selecting one of plural multi-dimensional interleaving schemes;
- and
- allocating data units from the coded block over one or more of the multiple transmit antennas using the selected multi-dimensional interleaving scheme;
- and
- wherein the selected channel coding scheme and interleaving scheme are selected to optimize a performance of the data block transmission for the determined one or more radio channel characteristics and the one or more diversity conditions.
A radio node for communicating blocks of data over a radio interface, comprising:
- radio circuitry;
- multiple antennas coupled to the radio circuitry, each antenna being associated with at least one corresponding radio channel and each data block including multiple data units;
- and
- processing circuitry configured to:
- determine one or more characteristics of the radio channels associated with the multiple antennas;
- determine one or more diversity conditions of the radio channels;
- based on the determined one or more radio channel characteristics, select one of plural channel coding schemes to code a data block;
- based on the determined one or more diversity conditions, select one of plural multi-dimensional interleaving schemes to allocate data units from the coded block over one or more of the multiple transmit antennas,
- wherein the processing circuitry is configured to select the channel coding scheme and the interleaving scheme to optimize a performance of the data block transmission for the determined one or more radio channel characteristics and the determined one or more diversity conditions.
