An information processing method performed by a terminal device (800, 900), the method comprising: receiving, by the terminal device (800, 900), first Downlink Control Information, DCI, on a first active Bandwidth Part, BWP, of a first component carrier, CC, wherein the first DCI is transmitted on a resource indicated by a first Control Resource Set, CORESET, corresponding to the first active BWP, a first Physical Downlink Shared Channel, PDSCH, scheduled by the first DCI is carried on a second active BWP of a second CC, the first active BWP corresponds to at least two CORESET pools, and pool indexes corresponding to different CORESET pools are different; wherein the first CORESET belongs to a first CORESET pool of the at least two CORESET pools; wherein the method further comprises: determining, by the terminal device (800, 900), a first target Transmission Configuration Indication, TCI, state, wherein the first target TCI state is used to receive the first PDSCH; wherein in response to that the first CC and the second CC are the same CC, and a scheduling time interval of the first DCI is smaller than a first threshold, the first target TCI state comprises: a TCI state corresponding to a second CORESET, wherein the scheduling time interval of the first DCI refers to a time offset between reception of the first DCI and the PDSCH; wherein the second CORESET comprises: a CORESET with a lowest identity among CORESETs corresponding to a pool index in a latest downlink time slot on the first active BWP detected by the terminal device (800, 900); in response to that the first CC and the second CC are different CCs and the first DCI does not carry a TCI state indication field or the scheduling time interval of the first DCI is smaller than the first threshold, the first target TCI state comprises: a TCI state with a lowest identity among active TCI states corresponding to a downlink data channel on the second active BWP. receiving, by the terminal device (800, 900), first Downlink Control Information, DCI, on a first active Bandwidth Part, BWP, of a first component carrier, CC, wherein the first DCI is transmitted on a resource indicated by a first Control Resource Set, CORESET, corresponding to the first active BWP, a first Physical Downlink Shared Channel, PDSCH, scheduled by the first DCI is carried on a second active BWP of a second CC, the first active BWP corresponds to at least two CORESET pools, and pool indexes corresponding to different CORESET pools are different;
