Abstract
A technique for performing a multi-layer transmission from a transmitting station to a receiving station on a radio frequency is described. The multi-layer transmission comprises multiple layers (902, 904) having different robustnesses on the radio frequency. As to a method aspect of the technique, a first portion (802.1) of first data (802) and a first portion (804.1) of second data (804) on a first layer (902) of the multi-layer transmission and, simultaneously on a second layer (904) of the multi-layer transmission, a second portion (802.2) of the first data (802) and a second portion (804.2) of the second data (804) are transmitted.

A method of performing a multi-intra-symbol-layer transmission from a transmitting station to a receiving station on a radio frequency, wherein each of a plurality of intra-symbol layers of a same modulation symbol has different robustnesses on the radio frequency, the method comprising:
- transmitting, on a first intra-symbol layer of the multi-intra-symbol-layer transmission, a first portion of first data and a first portion of second data and, simultaneously on a second intra-symbol layer of the multi-intra-symbol-layer transmission, a second portion of the first data and a second portion of the second data;
- wherein a size of the first portion of the first data, the second portion of the first data, the first portion of the second data, and/or the second portion of the second data depends on a signal to noise ratio (SNR) and/or a signal to interference and noise ratio (SINR) at the receiving station.
A method of performing a multi-intra-symbol-layer reception from a transmitting station at a receiving station on a radio frequency, wherein each of a plurality of intra-symbol layers of a same modulation symbol has different robustnesses on the radio frequency, the method comprising:
- receiving, on a first intra-symbol layer of the multi-intra-symbol-layer reception, a first portion of first data and a first portion of second data and, simultaneously on a second intra-symbol layer of the multi-intra-symbol-layer reception, a second portion of the first data and a second portion of the second data;
- wherein a size of the first portion of the first data, the second portion of the first data, the first portion of the second data, and/or the second portion of the second data depends on a signal to noise ratio (SNR) and/or a signal to interference and noise ratio (SINR) at the receiving station.
A transmit device for performing a multi-intra-symbol-layer transmission from a transmitting station to a receiving station on a radio frequency, wherein each of a plurality of intra-symbol layers of a same modulation symbol has different robustnesses on the radio frequency, the transmit device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the transmit device is operative to:
- transmit, on a first intra-symbol layer of the multi-intra-symbol-layer transmission, a first portion of first data and a first portion of second data and, simultaneously on a second intra-symbol layer of the multi-intra-symbol-layer transmission, a second portion of the first data and a second portion of the second data;
- wherein a size of the first portion of the first data, the second portion of the first data, the first portion of the second data, and/or the second portion of the second data depends on a signal to noise ratio (SNR) and/or a signal to interference and noise ratio (SINR) at the receiving station.
A receive device for performing a multi-intra-symbol-layer reception from a transmitting station at a receiving station on a radio frequency, wherein each of a plurality of intra-symbol layers of a same modulation symbol has different robustnesses on the radio frequency, the receive device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the receive device is operative to:
- receive, on a first intra-symbol layer of the multi-intra-symbol-layer reception, a first portion of first data and a first portion of second data and, simultaneously on a second intra-symbol layer of the multi-intra-symbol-layer reception, a second portion of the first data and a second portion of the second data;
- wherein a size of the first portion of the first data, the second portion of the first data, the first portion of the second data, and/or the second portion of the second data depends on a signal to noise ratio (SNR) and/or a signal to interference and noise ratio (SINR) at the receiving station.
