1. A search space allocation method performed by a terminal device, comprising:
in a case that a plurality of transmission and reception points (TRPs) is configured for the terminal device, discarding part of search spaces configured for the terminal device in a case that a quantity of first monitoring objects in a search space set configured for the terminal device exceeds a limit of first monitoring objects that can be monitored by the terminal device, wherein
at least one first monitoring object comprises a physical downlink control channel (PDCCH) candidate or a non-overlapping control channel element (CCE);
wherein the discarding part of search spaces configured for the terminal device comprises:
discarding part or all UE-specific search spaces (USSs) associated with a first transmission object, wherein
the first transmission object comprises a first control resource set (CORESET), and the first CORESET comprises at least one CORESET in CORESETs configured for the terminal device to monitor search spaces;
wherein the first CORESET is a CORESET associated with a specific TRP among target CORESETs.
