PT-RS configuration depending on scheduling parameters
There is disclosed a transmitting node for a Radio Access Network, the transmitting node being adapted for transmitting, based on one or more transmission parameters, of reference signaling, and/or signaling including reference signaling, wherein the reference signaling comprises phase tracking reference signaling, and the one or more transmission parameters comprise a Modulation and Coding Scheme (MCS).
1. A transmitting node configured for use in a Radio Access Network, the transmitting node comprising:
control circuitry; and
radio circuitry;
wherein the control circuitry and radio circuitry are configured to transmit, based on one or more transmission parameters, reference signaling and/or signaling including reference signaling, wherein the presence or not of phase tracking reference signaling in the reference signaling depends on a number of scheduled spatial layers for the transmission and wherein the one or more transmission parameters comprise a Modulation and Coding Scheme (MCS).
2. The transmitting node of claim 1 , wherein the one or more transmission parameters are configured or indicated with a downlink control information (DCI) message.
3. The transmitting node of claim 1 , wherein the transmitting node is a terminal or a network node.
4. The transmitting node of claim 1 , wherein the transmitting node is configured to transmit in downlink, and wherein the transmitting node is configured to transmit terminal-specific and/or beam-formed reference signaling and/or signaling including reference signaling.
5. A method for operating a transmitting node in a Radio Access Network, the method comprising:
transmitting, based on one or more transmission parameters, reference signaling and/or signaling including reference signaling, wherein the presence or not of phase tracking reference signaling in the reference signaling depends on a number of scheduled spatial layers for the transmission and wherein the one or more transmission parameters comprise a Modulation and Coding Scheme (MCS).
6. The method of claim 5 , wherein the one or more transmission parameters are configured or indicated with a downlink control information (DCI) message.
7. The method of claim 5 , wherein the transmitting node is a terminal or a network node.
8. The method of claim 5 , wherein said transmitting is in downlink, and wherein said transmitting is terminal-specific and/or beam-formed.
9. A non-transitory computer-readable medium comprising, stored thereupon, code executable by control circuitry of a transmitting node, the code being configured to cause the control circuitry to control the transmitting node to transmit, based on one or more transmission parameters, reference signaling and/or signaling including reference signaling, wherein the presence or not of phase tracking reference signaling in the reference signaling depends on a number of scheduled spatial layers for the transmission and wherein the one or more transmission parameters comprise a Modulation and Coding Scheme (MCS).
