Abstract
User equipment includes a control unit configured to determine a spatial reception parameter of a channel, based on quasi co-location (QCL) information related to a synchronization signal or a reference signal; and a reception unit configured to receive the channel based on the determined spatial reception parameter. In the QCL information, a QCL parameter applied to a source signal is partially or entirely different from a QCL parameter applied to a destination signal.
Claims4
A communication method comprising:
- determining a spatial reception parameter of a channel, based on quasi co-location (QCL) information related to a synchronization signal or a reference signal;
- and
- receiving the channel based on the determined spatial reception parameter,
- wherein, in the QCL information, a QCL parameter applied to a source signal is partially or entirely different from a QCL parameter applied to a destination signal,
- wherein the QCL information is defined by a plurality of source signals or a plurality of destination signals, and
- wherein the QCL information includes information indicating a QCL accuracy level or priority, and the accuracy level or priority is defined based on ranges of beams, applied to the plurality of source signals or the plurality of destination, signals, in which received power greater than or equal to a predetermined value is detected in a case where the beams are transmitted with a same transmission power at a predetermined distance.
