Abstract
Methods and apparatus for configuring, in a network node of a wireless communication network, a reference signal resource. An example method comprises obtaining a combination of one or more components to be used for a reference signal resource, the one or more components being contained in one or more physical resource blocks of a slot; and indicating, to the one or more wireless devices, the combination of the one or more components in the one or more physical resource blocks that are to be used for the reference signal resource.
Claims18
A method of configuring, in a network node of a wireless communication network, a reference signal resource in the wireless communication network, the method comprising:
- obtaining a combination of a plurality of components to be used for a reference signal resource, the one or more components being contained in one or more physical resource blocks of a slot;
- and
- indicating, to one or more wireless devices, the combination of the plurality of components in the one or more physical resource blocks that are to be used for the reference signal resource,
- wherein the physical resource block spans a plurality of subcarriers, and wherein indicating the combination of the one or more components includes indicating one or more subcarrier indexes,
- wherein the indication of the one or more subcarrier indexes includes a bitmap, and
- wherein each bit in the bitmap uniquely corresponds to a subcarrier index and a set bit in the bitmap indicates that a component located at a subcarrier index corresponding to the set bit is part of the combination of one or more components used for the reference signal resource.
A method of obtaining, in a wireless device of a wireless communication network, an indication of a reference signal resource in the wireless communication network, the method comprising:
- receiving an indication, from a network node, of a combination of a plurality of components contained in one or more physical resource blocks of a slot;
- and
- using the indicated combination of the plurality of components for a reference signal resource,
- wherein the physical resource block spans a plurality of subcarriers, and wherein indicating the combination of the plurality of components includes indicating one or more subcarrier indexes,
- wherein the indication of the one or more subcarrier indexes includes a bitmap, and
- wherein each bit in the bitmap uniquely corresponds to a subcarrier index and a set bit in the bitmap indicates that a component located at a subcarrier index corresponding to the set bit is part of the combination of a plurality of components used for the reference signal resource.
A user equipment (UE) for facilitating communications in a wireless communication network by obtaining an indication of a reference signal resource in the wireless communication network, the UE comprising:
- an antenna configured to send and receive wireless signals;
- a transceiver connected to the antenna and to processing circuitry, and configured to condition signals communicated between the antenna and the processing circuitry;
- the processing circuitry being configured to:
- receive an indication, from a network node, of a combination of a plurality of components contained in one or more physical resource blocks of a slot;
- and
- use the indicated combination of the plurality of components for a reference signal resource,
- wherein the physical resource block spans a plurality of subcarriers, and wherein indicating the combination of the plurality of components includes indicating one or more subcarrier indexes,
- wherein the indication of the one or more subcarrier indexes includes a bitmap, and
- wherein each bit in the bitmap uniquely corresponds to a subcarrier index and a set bit in the bitmap indicates that a component located at a subcarrier index corresponding to the set bit is part of the combination of a plurality of components used for the reference signal resource.
