Abstract
Method and device for notifying reference signal configuration information are disclosed. Channel state information-reference signal (CSI-RS) configuration information is coded to obtain one or more CSI-RS configuration codes. The CSI-RS configuration codes are sent to a terminal device. The terminal device determines, based on CSI-RS configuration codes, CSI-RS configuration information such as a quantity of antenna ports for transmitting a CSI-RS, a CSI-RS pattern, a CSI-RS period and an offset corresponding to the CSI-RS period.
Claims16
A method, comprising:
- receiving, by a terminal device from a base station through a downlink channel, a channel state information-reference signal (CSI-RS) configuration information code, the CSI-RS configuration information code comprising a first code and a third code;
- determining, by the terminal device, a CSI-RS pattern based on the first code and a first relationship, the first relationship comprising a relationship among the first code, the quantity of antenna ports of the base station to transmit the CSI-RS and the CSI-RS pattern;
- and
- determining, by the terminal device, a data muting resource element (RE) according to the third code.
An apparatus, comprising:
- a storage medium for storing program instructions;
- and
- at least one processor coupled to the storage medium, wherein the instructions, when executed by the at least one processor, cause the apparatus to:
- receive, through a downlink channel, a channel state information-reference signal (CSI-RS) configuration information code, the CSI-RS configuration information code comprising a first code and a third code;
- determine a CSI-RS pattern based on the first code and a first relationship, the first relationship comprising a relationship among the first code, the quantity of antenna ports of the base station to transmit the CSI-RS, and the CSI-RS pattern;
- and
- determine a data muting resource element (RE) according to the third code.
A method, comprising:
- determining, by a base station, a channel state information-reference signal (CSI-RS) configuration information code;
- sending, by the base station to a terminal device through a downlink channel, the CSI-RS configuration information code, the CSI-RS configuration information code comprising a first code and a third code, the first code indicating the quantity of antenna ports of the base station to transmit the CSI-RS and a CSI-RS pattern, and the third code indicating a data muting resource element (RE).
An apparatus, comprising:
- a storage medium for storing program instructions;
- and
- at least one processor coupled to the storage medium;
- wherein the instructions, when executed by the processor, cause the apparatus to:
- determine a channel state information-reference signal (CSI-RS) configuration information code;
- send, to a terminal device through a downlink channel, the CSI-RS configuration information code, the CSI-RS configuration information code comprising a first code and a third code, wherein:
- the first code indicates the quantity of antenna ports of the base station to transmit the CSI-RS and a CSI-RS pattern, and
- the third code indicates a data muting resource element (RE).
