Abstract
Relating to the field of wireless communications, a method and an apparatus for determining a signal-to-noise ratio in wireless communication are provided. The method includes: determining an effective signal-to-noise ratio of a received signal of current user equipment in the wireless communication; acquiring at least one parameter used to correct the effective signal-to-noise ratio; and determining, based on a mapping relationship used to correct the effective signal-to-noise ratio, a corrected signal-to-noise ratio corresponding to the at least one parameter and the effective signal-to-noise ratio.
Claims14
A method, comprising:
- determining an effective signal-to-noise ratio of a received signal of current user equipment in a wireless communication;
- acquiring a first parameter used to correct the effective signal-to-noise ratio, wherein the first parameter comprises:
- a second parameter indicating a receiver algorithm used by the current user equipment and a third parameter of an interference signal;
- determining, based on a mapping relationship for correcting the effective signal-to-noise ratio, a corrected signal-to-noise ratio corresponding to the first parameter and the effective signal-to-noise ratio;
- determining channel state information based on the corrected signal-to-noise ratio;
- and
- reporting the channel state information to a serving station of the current user equipment, to cause the serving station to communicate with the user equipment based on the channel state information.
An apparatus, comprising:
- a memory, configured to store a first parameter for correcting an effective signal-to-noise ratio of a received signal of current user equipment in a wireless communication, wherein the first parameter comprises:
- a second parameter indicating a receiver algorithm used by the current user equipment and a third parameter of an interference signal;
- a processor, configured to:
- determine the effective signal-to-noise ratio;
- acquire the first parameter from the memory;
- determine, based on a mapping relationship for correcting the effective signal-to-noise ratio, a corrected signal-to-noise ratio corresponding to the first parameter and the effective signal-to-noise ratio;
- determine channel state information based on the corrected signal-to-noise ratio;
- and
- report the channel state information to a serving station of the current user equipment, to cause the serving station to communicate with the user equipment based on the channel state information.
