In particular, a UE can connect to a plurality of cells in a network. The UE can determine a reference slot length according to an SCS of a first cell of the plurality of cells. ## Claims ### Claim 1 A method, comprising: connecting, by a user equipment (UE), to a plurality of cells in a network, wherein the plurality of cells have at least two cells with different sub-carrier spacings (SCSs), and wherein the plurality of cells include specific cells for physical downlink control channel (PDCCH), physical uplink shared channel PUSCH) and channel state information reference signal (CSI-RS), and the SCS of the first cell is the minimum SCS among SCSs of the specific cells; and determining, by the UE, a reference slot length according to an SCS of a first cell of the plurality of cells, wherein the SCS of the first cell is a minimum SCS among SCSs of the plurality of cells. ### Claim 2 (depends on 1) The method of claim 1, wherein the reference slot length is equal to a length of one slot corresponding to the SCS of the first cell. ### Claim 3 (depends on 1) The method of claim 1, wherein a beginning of the reference slot length is aligned with a first slot of a specific cell for physical downlink control channel (PDCCH). ### Claim 4 (depends on 3) The method of claim 3, further comprising: receiving, by the UE, a single channel state information (CSI) request by PDCCH from the specific cell within the reference slot length in a cell group; or canceling, by the UE, expecting to receive more than one CSI request by PDCCH from the specific cell within the reference slot length in a cell group. ### Claim 5 (depends on 4) The method of claim 4, wherein the CSI request is included in a downlink control information (DCI). ### Claim 6 (depends on 1) The method of claim 1, wherein a beginning of the reference slot length is aligned with a first slot of a specific cell for physical uplink shared channel (PUSCH). ### Claim 7 (depends on 6) The method of claim 6, further comprising: receiving, by the UE, single channel state information (CSI) report request by PUSCH from the specific cell within the reference slot length in a cell group; or canceling, by the UE, expecting to receive more than one CSI report request by PUSCH from the specific cell within the reference slot length in a cell group. ### Claim 8 (depends on 1) The method of claim 1, wherein each SCS of the plurality of cells is one of 15 kHz, 30 kHz, 60 kHz, 120 KHz and 240 KHz. ### Claim 9 A user equipment (UE) comprising: a transceiver that: connects to a plurality of cells in a network, wherein the plurality of cells have at least two cells with different sub-carrier spacings (SCSs), and wherein the plurality of cells include specific cells for physical downlink control channel (PDCCH), physical uplink shared channel (PUSCH) and channel state information reference signal (CSI-RS), and the SCS of the first cell is the minimum SCS among SCSs of the specific cells, and the SCS of the first cell is the minimum SCS among SCSs of the specific cells; a scheduling circuit that: determines a reference slot length according to an SCS of a first cell of the plurality of cells, wherein the SCS of the first cell is a minimum SCS among SCSs of the plurality of cells. ### Claim 10 (depends on 9) The UE of claim 9, wherein the reference slot length is equal to a length of one slot corresponding to the SCS of the first cell. ### Claim 11 (depends on 9) The UE of claim 9, wherein the reference slot length is aligned with a first slot of a specific cell for physical downlink control channel (PDCCH). ### Claim 12 (depends on 11) The UE of claim 11, wherein the transceiver further: receives a single channel state information (CSI) request by PDCCH from the specific cell within the reference slot length in a cell group; or cancels expecting to receive more than one CSI request by PDCCH from the specific cell within the reference slot length in a cell group. ### Claim 13 (depends on 12) The UE of claim 12, wherein the CSI request is included in a downlink control information (DCI). ### Claim 14 (depends on 9) The UE of claim 9, wherein the reference slot length is aligned with a first slot of a specific cell for physical uplink shared channel (PUSCH). ### Claim 15 (depends on 14) The UE of claim 14, wherein the transceiver further: receives single channel state information (CSI) report request by PUSCH from the specific cell within the reference slot length in a cell group; or cancels expecting to receive more than one CSI report request by PUSCH from the specific cell within the reference slot length in a cell group. ### Claim 16 (depends on 9) The UE of claim 9, wherein each SCS of the plurality of cells is one of 15 kHz, 30 kHz, 60 kHz, 120 KHz and 240 KHz.
