Abstract
Disclosed are a data transmission method and apparatus. The method includes encoding a data stream of a first receive end by using a first encoding mode, to obtain a first encoded data stream. The method also includes encoding a data stream of a second receive end by using a second encoding mode, to obtain a second encoded data stream. The method also includes encoding the first encoded data stream and the second encoded data stream by using a third encoding mode, to obtain a to-be-sent data stream. The method also includes sending the to-be-sent data stream to a corresponding receive end by using antennas.

A method, comprising:
- encoding a data stream of a first receive end using a first encoding mode, to obtain a first encoded data stream, wherein the first encoding mode corresponds to a Multiple Input Multiple Output (MIMO) transmission mode used by the first receive end, wherein the first encoding mode is a first MIMO precoding mode;
- encoding a data stream of a second receive end using a second encoding mode, to obtain a second encoded data stream, wherein the second encoding mode corresponds to a MIMO transmission mode used by the second receive end, wherein the second encoding mode is a second MIMO precoding mode;
- encoding the first encoded data stream and the second encoded data stream using a third encoding mode, to obtain a to-be-sent data stream;
- and
- sending the to-be-sent data stream to a corresponding receive end using a plurality of antennas.
An apparatus, comprising:
- a user encoding module, configured to:
- encode a data stream of a first receive end using a first encoding mode, to obtain a first encoded data stream, wherein the first encoding mode corresponds to a Multiple Input Multiple Output (MIMO) transmission mode used by the first receive end, wherein the first encoding mode is a first MIMO precoding mode;
- and
- encode a data stream of a second receive end using a second encoding mode, to obtain a second encoded data stream, wherein the second encoding mode corresponds to a MIMO transmission mode used by the second receive end, wherein the second encoding mode is a second MIMO precoding mode;
- a precoding module, configured to encode the first encoded data stream and the second encoded data stream using a third encoding mode, to obtain a to-be-sent data stream;
- and
- a transmission module, configured to send the to-be-sent data stream to a corresponding receive end using a plurality of antennas.
An apparatus, comprising:
- a plurality of antennas;
- a processor, and
- a non-transitory processor-readable medium having processor-executable instructions stored thereon that, when executed by the processor, cause the processor to:
- encode a data stream of a first receive end using a first encoding mode, to obtain a first encoded data stream, wherein the first encoding mode corresponds to a Multiple Input Multiple Output (MIMO) transmission mode used by the first receive end, wherein the first encoding mode is a first MIMO precoding mode;
- encode a data stream of a second receive end using a second encoding mode, to obtain a second encoded data stream, wherein the second encoding mode corresponds to a MIMO transmission mode used by the second receive end, wherein the second encoding mode is a second MIMO precoding mode;
- encode the first encoded data stream and the second encoded data stream using a third encoding mode, to obtain a to-be-sent data stream;
- and
- a transmitter, configured to send the to-be-sent data stream to a corresponding receive end using the plurality of antennas.
