Abstract
Embodiments of the application relate to the communications field, and disclose a channel quality information calculation method, apparatus, and system. The method includes: receiving, by a terminal, a downlink configuration instruction sent by an access network device; performing, by the terminal, measurement on a reference signal resource indicated by the downlink configuration instruction, to obtain first channel quality information, and sending the first channel quality information to the access network device; sending, by the terminal, an SRS to the access network device; and calculating, by the access network device, second channel quality information based on the first channel quality information and the SRS.
Claims15
A channel quality information calculation method, comprising:
- receiving, by a terminal, a downlink configuration instruction sent by an access network device;
- performing, by the terminal, measurement on a reference signal resource indicated by the downlink configuration instruction, to obtain first channel quality information, and sending the first channel quality information to the access network device, wherein the first channel quality information is used to feed_back received signal information or interference information obtained through measurement on the reference signal resource;
- and
- sending, by the terminal, a sounding reference signal SRS to the access network device, wherein the first channel quality information and the SRS are used to calculate second channel quality information.
A channel quality information calculation method, comprising:
- sending, by an access network device, a downlink configuration instruction to a terminal;
- receiving, by the access network device, first channel quality information sent by the terminal, wherein the first channel quality information is obtained by the terminal through measurement on a reference signal resource indicated by the downlink configuration instruction;
- and
- receiving, by the access network device, a sounding reference signal SRS sent by the terminal according to the downlink configuration instruction, wherein the first channel quality information and the SRS are used to calculate second channel quality information.
A channel quality information calculation apparatus, wherein the apparatus comprises:
- a receiver, configured to receive a downlink configuration instruction sent by an access network device;
- a processor configured to:
- perform measurement on a reference signal resource indicated by the downlink configuration instruction, to obtain first channel quality information, and send the first channel quality information to the access network device, wherein the first channel quality information is used to feed back received signal information or interference information obtained through measurement on the reference signal resource;
- and
- a transmitter;
- configured to send a sounding reference signal SRS to the access network device, wherein the first channel quality information and the SRS are used to calculate second channel quality information.
A channel quality information calculation apparatus, comprising:
- a transmitter, configured to send a downlink configuration instruction to a terminal;
- and
- a receiver configured to receive first channel quality information sent by the terminal;
- wherein the first channel quality information is obtained by the terminal through measurement on a reference signal resource indicated by the downlink configuration instruction;
- wherein the receiver is further configured to receive a sounding reference signal SRS sent by the terminal according to the downlink configuration instruction;
- wherein the first channel quality information and the SRS are used to calculate second channel quality information.
