Abstract
Methods and apparatuses are disclosed for channel estimation. According to an embodiment, a network node obtains, from a terminal device, a channel quality indication (CQI) value reported by the terminal device for an anchor physical resource block (PRB). The network node determines, for the anchor PRB, a first signal to interference plus noise ratio (SINR) of a downlink channel, based at least on the CQI value.
Claims19
A method performed by a network node, comprising:
- obtaining, from a terminal device, a channel quality indication, CQI, value reported by the terminal device for an anchor physical resource block, PRB;
- and
- determining, for the anchor PRB, a first signal to interference plus noise ratio, SINR, of a downlink channel, based at least on the CQI value.
A method performed by a terminal device, comprising:
- reporting, to a network node, a channel quality indication, CQI, value for an anchor physical resource block, PRB,
- wherein the CQI value is used for determining a first signal to interference plus noise ratio, SINR, of a downlink channel for the anchor PRB and/or a second SINR of the downlink channel for a non-anchor PRB.
