Two-Level Mobility Reference Signal Configuration

A method, in a wireless device operating in a wireless communication system, the method comprising:

• receiving, from a network node in the wireless communication system, mobility or measurement reference signal (MRS) configuration information, the MRS configuration information specifying one or more parameters for each of a plurality of MRS configurations;
• receiving, from a network node in the wireless communication system, an activation command indicating that at least a first one of the MRS configurations is to be used by the wireless device, the activation command including an index identifying the first one of the MRS configurations from among the plurality of MRS configurations;
• and
• performing at least one measurement on at least one MRS specified by the first one of the MRS configurations.

An arrangement of one or more network nodes of a wireless communication system, wherein each of the one or more network nodes comprises:

• a transceiver circuit configured to communicate with a wireless device operating in the wireless communication system;
• and
• a processing circuit operatively associated with the transceiver circuit,
• wherein one or more processing circuits of the one or more network nodes are configured to:
• send, to the wireless device, mobility or measurement reference signal (MRS) configuration information, the MRS configuration information specifying one or more parameters for each of a plurality of MRS configurations;
• and
• send, to the wireless device, an activation command indicating that at least a first one of the MRS configurations is to be used by the wireless device, the activation command including an index identifying the first one of the MRS configurations from among the plurality of MRS configurations.

A wireless device of a wireless communication system, comprising:

• a transceiver circuit configured to communicate with one or more network nodes operating in the wireless communication system;
• and
• a processing circuit operatively associated with the transceiver circuit and configured to:
• receive, from a network node, mobility or measurement reference signal (MRS) configuration information, the MRS configuration information specifying one or more parameters for each of a plurality of MRS configurations;

• and
• perform at least one measurement on at least one MRS specified by the first one of the MRS configurations.

A non-transitory computer readable storage medium storing a computer program comprising program instructions that, when executed on at least one processing circuit of a wireless device in a wireless communication system, configures the wireless device to:

• receive, from a network node operating in the wireless communication system, mobility or measurement reference signal, MRS, configuration information, the MRS configuration information specifying one or more parameters for each of a plurality of MRS configurations;
• receive, from a network node in the wireless communication system, an activation command indicating that at least a first one of the MRS configurations is to be used by the wireless device, the activation command including an index identifying the first one of the MRS configurations from among the plurality of MRS configurations;
• and
• perform at least one measurement on the at least one MRS specified by the first one of the MRS configurations.
