To meet different performance requirements of various application scenarios, research on a New air interface technology (NR, new Radio) (or 5G) is decided at the 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) #72 full-time, and standardization Work on NR is started at the 3GPP RAN #75 full-time WI (Work Item) that passes the New air interface technology (NR, new Radio).

A first node device according to any of claims 1-3, characterized in that a target indication value is one of the W1 indication values, and CCEs occupied by PDCCH candidates employing the first aggregation level corresponding to the target indication value in the first search space set depend on the PDCCH candidate number value employing the first aggregation level of the cell into which the PDCCH candidates of the cell set corresponding to the target indication value are scheduled.

5. The first node device of any of claims 1-4, wherein the first transceiver transmits a second information block, wherein the second information block is used to indicate a set of capability parameters of a sender of the second information block, the set of capability parameters of the sender of the second information block including at least a first parameter used to indicate a maximum number of downlink cells supported by the sender of the second information block that are simultaneously scheduled by one PDCCH and a second parameter used to indicate a maximum number of uplink cells supported by the sender of the second information block that are simultaneously scheduled by one PDCCH.

6. The first node device of any of claims 1-5, wherein the plurality of PDCCH candidates include a first PDCCH candidate and a second PDCCH candidate, the first PDCCH candidate being for a first DCI format, the second PDCCH candidate being for a second DCI format, the first DCI format being equal in size to the second DCI format, the first DCI format being used to schedule one of the W1 sets of cells, the second DCI format being used to schedule the other of the W1 sets of cells, or the second DCI format being used to schedule only one cell, the aggregation level of the first PDCCH candidate and the aggregation level of the second PDCCH candidate being equal, the index of the set of control resources to which the first PDCCH candidate belongs being equal to the index of the set of control resources to which the second PDCCH candidate belongs, the first node device being capable of receiving PDCCHs carrying the first DCI on the second PDCCH candidate.

7. The first node device according to any of claims 1-6, wherein the first information block indicates W2 cell combinations, any one of the W2 cell combinations comprising at least one cell, W2 being a positive integer greater than 1, all cells included in the W2 cell combinations belonging to the same one of the W1 cell sets, and wherein a target combination is one of the W2 cell combinations, an index value of the one cell included in the target combination being an order in which the cell is in ascending order of serving cell index in the cell set to which the cell belongs, at least one PDCCH candidate of the plurality of PDCCH candidates indicating the target combination from the W2 cell combinations.
