Abstract
A resource configuration method and apparatus of reference signal and a communications system. The resource configuration method includes: configuring one or more resources by a base station for a first reference signal which is precoded with one or more beam weighting coefficients, and configuring one or more resources for a second reference signal which is not precoded with one or more beam weighting coefficients or precoding of which is unknown to a UE; and transmitting one or more resource configurations of the first reference signal and one or more resource configurations of the second reference signal to the UE. Hence, a 3D MIMO system may flexibly support reference signals of multiple types.
Claims17
A base station comprising:
- a processor configured to execute instructions to configure one or more resources for a first reference signal which is precoded with one or more beam weighting coefficients, and to configure one or more resources for a second reference signal which is not precoded with one or more beam weighting coefficients or precoding of which is unknown to a UE (user equipment);
- and
- transmitter configured to transmit one or more resource configurations of the first reference signal and one or more resource configurations of the second reference signal to the UE,
- wherein the transmitter is configured to trigger or activate the first reference signal by transmitting an activation of channel state information reference signal (CSI-RS) resources media access control (MAC) control element (CE) after transmitting the one or more resource configurations of the first reference signal, and to transmit the second reference signal while transmitting the one or more resource configurations of the second reference signal.
A user equipment (UE) comprising:
- a receiver configured to receive one or more resource configurations of a first reference signal which is precoded with one or more beam weighting coefficients and one or more resource configurations of a second reference signal which is not precoded with one or more beam weighting coefficients or precoding of which is unknown to the UE, transmitted by a base station;
- and
- a processor configured to execute instructions to detect the first reference signal upon reception of signaling for indicating to report a measurement result of the first reference signal after receiving the one or more resource configurations of the first reference signal, and to detect the second reference signal when the one or more resource configurations of the second reference signal is received.
A communications system, comprising:
- a base station, wherein the base station comprises a memory that stores a plurality of instructions, a processor that couples to the first memory and is configured to execute the instructions to configure one or more resources for a first reference signal which is precoded with one or more beam weighting coefficients, to configure one or more resources for a second reference signal which is not precoded with one or more beam weighting coefficients or precoding of which is unknown to a User Equipment, (UE), and a transmitter configured to transmit one or more resource configurations of the first reference signal and one or more resource configurations of the second reference signal;
- and
- the UE, wherein the UE comprises a receiver configured to receive the one or more resource configurations of the first reference signal and the one or more resource configurations of the second reference signal;
- wherein the transmitter is configured to trigger or activate the first reference signal by transmitting an activation of channel state information reference signal (CSI-RS) resources media access control (MAC) control element (CE) after transmitting the one or more resource configurations of the first reference signal, and to transmit the second reference signal while transmitting the one or more resource configurations of the second reference signal.
