Method and device for determining channel state information-reference signal transmission resource

A User Equipment (UE), comprising:

• a processor;
• a memory connected to the processor via a bus interface and configured to store therein programs and data for the operation of the processor;
• and
• a transceiver configured to be in communication with any other devices over a transmission medium,
• wherein the processor is configured to call and execute the programs and the data stored in the memory to:
• acquire uplink/downlink subframe configuration information for determining a position of a Channel State Information-Reference Signal (CSI-RS) resource;
• determine a type of a subframe within which a CSI-RS is to be transmitted in accordance with the uplink/downlink subframe configuration information;
• and
• determine the position of the CSI-RS resource within the subframe within which the CSI-RS is to be transmitted in accordance with the determined type of the subframe,
• wherein one or more types of subframes within which the CSI-RS is to be transmitted are determined by the first determination unit in accordance with the uplink/downlink subframe configuration information;
• the processor is further configured to call and execute the programs and the data stored in the memory to:
• in the case that one type of subframe within which the CSI-RS is to be transmitted is determined by the processor in accordance with the uplink/downlink subframe configuration information, determine the position of the CSI-RS resource in accordance with the one type of the subframe within which the CSI-RS is to be transmitted;
• and
• in the case that two or more types of subframes within which the CSI-RS is to be transmitted are determined by the processor in accordance with the uplink/downlink subframe configuration information, determine the position of the CSI-RS resource in accordance with each of the types of the subframes, to acquire a set of positions of the resources corresponding to each of the types of the subframes;
• and determine the set of the positions of the CSI-RS resources corresponding to each of the types of the subframes to be the position of the CSI-RS resource for receiving or measuring a downlink signal,
• wherein the processor is further configured to call and execute the programs and the data stored in the memory to, subsequent to determining, by the processor, the set of the positions of the CSI-RS resources corresponding to each of the types of the subframes to be the position of the CSI-RS resource for receiving or measuring the downlink signal;
• acquire a union of the sets of the positions of the CSI-RS resources corresponding to the types of the subframes, and receive or measure the downlink signal in accordance with the union;
• or
• receive or measure the downlink signal in accordance with the set of the positions of the CSI-RS resources corresponding to each of the types of the subframes.
