Abstract
The present invention relates to the field of communications network technologies, and discloses a data processing method and apparatus. In embodiments of the present invention, stream channel quality information is obtained, and then port mapping of a to-be-transmitted data stream is determined according to the stream channel quality information. The port mapping is used to make channel quality of data streams distributed in a same code word satisfy the following: a sum of fluctuation values that is used to represent channel quality of data streams in all code words is less than a sum of fluctuation values that is used to represent channel quality of data streams in all code words under original port mapping.
Claims13
A method, comprising:
- obtaining stream channel quality information, wherein the stream channel quality information represents channel quality of a channel on which a data stream is located;
- and
- determining port mapping of a to-be-transmitted data stream according to the stream channel quality information, wherein the port mapping is used to make channel quality of data streams distributed in a same code word satisfy a relation, the relation being that a sum of fluctuation values that represent channel quality of data streams in all code words is less than a sum of fluctuation values that represent channel quality of data streams in all code words in a case of original port mapping.
A method, comprising:
- receiving a downlink pilot signal that is sent by a network node;
- generating stream channel quality information according to the downlink pilot signal, wherein the stream channel quality information indicates channel quality of a channel on which a data stream is located;
- and
- sending the stream channel quality information to the network node.
An apparatus, comprising:
- a non-transitory memory, configured to store information comprising a program instruction;
- and
- a receiver, configured to receive a downlink pilot signal that is sent by a network node, and provide the downlink pilot signal to a processor;
- the processor, coupled to the memory, the receiver, and a transmitter, configured to execute the program to:
- generate stream channel quality information according to the downlink pilot signal, wherein the stream channel quality information represent channel quality of a channel on which a data stream is located;
- and
- provide the stream channel quality information to the transmitter;
- and
- the transmitter, configured to send the stream channel quality information to the network node.
