1. A method for monitoring a control channel, comprising:
determining, by a terminal according to first information configured by a network side device, at least two control resource sets (CORESETs) or search space sets having at least two Quasi-Co-Location Type D (QCL-Type D) properties, or determining, by the terminal according to a control channel transmission pattern configured by the network side device, at least two CORESETs or search space sets having an association relationship; and
monitoring, by the terminal, at least two control channels according to the at least two determined CORESETs or search space sets;
wherein the at least two determined CORESETs comprise:
a CORESET corresponding to a search space set of a second cell and one CORESET of a first cell, wherein the search space set of the second cell is a search space set with a lowest search space set index in the second cell; wherein the one CORESET of the first cell corresponds to a search space set associated with a search space set of the second cell; or
a CORESET corresponding to one search space set of a second cell and one CORESET of a third cell, wherein the one CORESET of the third cell corresponds to a search space set associated with the search space set of the second cell or corresponds to a search space set with a lower cell index and/or search space set index value; or
a CORESET corresponding to a first search space set of a second cell and one CORESET of a third cell, wherein the one CORESET of the third cell corresponds to a search space set associated with a second search space set of the second cell; wherein the first search space set of the second cell is a search space set with a lowest search space set index in the second cell;
wherein the second search space set of the second cell is one of a plurality of search space sets corresponding to the CORESET of the second cell; or
a CORESET of a second cell and a CORESET of a third cell; wherein the CORESET of the third cell corresponds to a search space set associated with a search space set of the second cell; wherein the search space set of the second cell corresponds to the CORESET of the second cell; or
a CORESET corresponding to one search space set of a fourth cell and a CORESET corresponding to one search space set of a fifth cell, wherein the one search space set of the fourth cell is a search space set with a lowest cell index and/or search space set index value among the search space sets having the association relationship, and the one search space set of the fifth cell is a search space set associated with the search space set of the fourth cell or corresponds to a search space set with a lower cell index and/or search space set index value.
