Method and apparatus for receiving signal

An apparatus for receiving a Channel State Information-Reference Signal (CSI-RS), comprising:

• a processor;
• and a memory storing codes, which, when executed by the processor, cause the processor to:
• receive signaling comprising configuration information of a Channel State Information-Reference Signal (CSI-RS);
• and
• acquire the configuration information of the CSI-RS from the signaling,
• wherein the configuration information comprises:
• a number of CSI-RS ports, RS resource pattern information and an inter-CSI-RS-port multiplexing scheme, and the RS resource pattern information and the inter-CSI-RS-port multiplexing scheme are jointly-coded in the signaling comprising the configuration information of the CSI-RS;
• wherein when the number of the CSI-RS ports is larger than 1, the CSI-RS has M candidate RS resource patterns, where M is an integer greater than 1;
• wherein the M candidate RS resource patterns are divided into a first pattern set and a second pattern set, each of the first pattern set and the second pattern set comprises one or more candidate RS resource patterns, a first multiplexing scheme is used for CSI-RS ports in each candidate RS resource pattern of the first pattern set, a second multiplexing scheme is used for CSI-RS ports in each candidate RS resource pattern of the second pattern set, and the first multiplexing scheme is different from the second multiplexing scheme;
• and
• wherein the first multiplexing scheme is a first code division multiplexing with an orthogonal code length of 2, the second multiplexing scheme is a second code division multiplexing with an orthogonal code length of 4.

A non-transitory computer-readable storage medium, storing an executable instruction which executes:

• receive signaling comprising configuration information of a Channel State Information-Reference Signal (CSI-RS);
• and
• acquire the configuration information of the CSI-RS from the signaling,
• wherein the configuration information comprises:
• a number of CSI-RS ports, RS resource pattern information and an inter-CSI-RS-port multiplexing scheme, and the RS resource pattern information and the inter-CSI-RS-port multiplexing scheme are jointly-coded in the signaling comprising the configuration information of the CSI-RS;
• wherein when the number of the CSI-RS ports is larger than 1, the CSI-RS has M candidate RS resource patterns, where M is an integer greater than 1;
• wherein the M candidate RS resource patterns are divided into a first pattern set and a second pattern set, each of the first pattern set and the second pattern set comprises one or more candidate RS resource patterns, a first multiplexing scheme is used for CSI-RS ports in each candidate RS resource pattern of the first pattern set, a second multiplexing scheme is used for CSI-RS ports in each candidate RS resource pattern of the second pattern set, and the first multiplexing scheme is different from the second multiplexing scheme;
• and
• wherein the first multiplexing scheme is a first code division multiplexing with an orthogonal code length of 2, the second multiplexing scheme is a second code division multiplexing with an orthogonal code length of 4.
