Abstract
Interference mitigation in SSB and/or TRS processing is described. An apparatus is configured to receive, from a network node, a reference signal associated with the network node and at least one neighboring network node. The apparatus is configured to obtain Rnn information from at least one noise tap of a CIR of the reference signal. The apparatus is also configured to apply a noise whitening to the CIR based on the Rnn information.
Claims20
An apparatus for wireless communication at a user equipment (UE), comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to:
- receive, from a network node, a reference signal associated with the network node and at least one neighboring network node;
- obtain cross-correlation matrix (Rnn) information from at least one noise tap of a channel impulse response (CIR) of the reference signal;
- and
- apply a noise whitening to the CIR based on the Rnn information.
A method of wireless communication at a user equipment (UE), comprising:
- receiving, from a network node, a reference signal associated with the network node and at least one neighboring network node;
- obtaining cross-correlation matrix (Rnn) information from at least one noise tap of a channel impulse response (CIR) of the reference signal;
- and
- applying a noise whitening to the CIR based on the Rnn information.
A non-transitory computer-readable medium storing computer executable code at a user equipment (UE), the code when executed by at least one processor causes the at least one processor to:
- receive, from a network node, a reference signal associated with the network node and at least one neighboring network node;
- obtain cross-correlation matrix (Rnn) information from at least one noise tap of a channel impulse response (CIR) of the reference signal;
- and
- apply a noise whitening to the CIR based on the Rnn information.
