Abstract
Embodiments of the present disclosure provide an information determination method and device, an electronic device and a storage medium. The method includes: determining a reference signal in a case where a preset condition is satisfied; and determining information of a downlink signal or downlink channel according to the reference signal. The embodiments of the present disclosure solve a problem that physical downlink shared channels (PDSCHs) of multiple component carriers (CCs) cannot be received normally due to conflict of the PDSCHs of the CCs in a time domain in the related art.

An information determination method comprising:
- determining a reference signal in a case where a preset condition is satisfied, wherein the preset condition comprises at least one of Transmission Configuration Indicator (TCI) states configured in a frequency domain bandwidth where a downlink signal or downlink channel is located comprises a quasi-colocated (QCL) reference signal associated with a spatial reception parameter;
- and
- determining a QCL assumption of the downlink signal or downlink channel according to the reference signal,
- wherein the reference signal is determined according to a relation between a carrier where a control channel for scheduling the downlink signal or downlink channel is located and a carrier where the downlink signal or downlink channel is located, wherein determining the reference signal according to the relation between the carrier where the control channel for scheduling the downlink signal or downlink channel is located and the carrier where the downlink signal or downlink channel is located comprises:
- acquiring the reference signal according to first-type parameters in a case where the carrier where the control channel for scheduling the downlink signal or downlink channel is located is different from the carrier where the downlink signal or downlink channel is located;
- and
- acquiring the reference signal according to second-type parameters in a case where the carrier where the control channel for scheduling the downlink signal or downlink channel is located is the same as the carrier where the downlink signal or downlink channel is located, wherein the first-type parameters and the second-type parameters are different;
- and
- wherein the information determination method further comprises determining the reference signal according to a type of the downlink signal and the relation between the carrier where the control channel for scheduling the downlink signal or downlink channel is located and the carrier where the downlink signal or downlink channel is located, wherein determining the reference signal according to the type of the downlink signal and the relation between the carrier where the control channel for scheduling the downlink signal or downlink channel is located and the carrier where the downlink signal or downlink channel is located comprises:
- in a case where the downlink signal comprises an aperiodic measurement reference signal, and the carrier where the aperiodic measurement reference signal is located is different from the carrier where the control channel for scheduling the aperiodic measurement reference signal is located, acquisition parameters of the reference signal comprise a QCL reference signal of Control Resource Set (CORESET) that satisfies a predetermined feature and is included in a time unit latest to the aperiodic measurement reference signal in the carrier where the aperiodic measurement reference signal is located;
- in a case where the downlink signal comprises a demodulation reference signal of a downlink data channel, and the carrier where the downlink data channel is located is different from the carrier where the control channel for scheduling the downlink data channel is located, acquisition parameters of the reference signal do not comprise a QCL reference signal of CORESET that satisfies the predetermined feature and is included in a time unit latest to the downlink data channel in a carrier where the demodulation reference signal of the downlink data channel is located,
- wherein the CORESET that satisfies the predetermined feature is CORESET with a minimum CORESET identifier (ID) in the time unit.
