A communication method, wherein the method comprises: determining, by a network device in a first time domain unit, whether data of N to-be-scheduled terminals in a second time domain unit in M cells of the network device is delay-sensitive data, wherein the M cells share a same remote radio unit, RRU; and if the network device determines that data of K to-be-scheduled terminals of the N to-be-scheduled terminals is delay-sensitive data, the K to-be-scheduled terminals are separately located in P cells of the M cells, and a power required for sending the delay-sensitive data in each of the P cells is less than or equal to a preset power threshold corresponding to the cell, sending, by the network device, the data of the K to-be-scheduled terminals in a second time domain unit of the P cells, wherein M, N, P, and K are integers greater than or equal to 1, K is less than or equal to N, and P is less than or equal to M; wherein the method further comprises: if the network device determines that a power required for sending the delay-sensitive data in a first cell of the P cells is greater than a preset power threshold corresponding to the first cell, sending, by the network device, the data of the N to-be-scheduled terminals in the second time domain unit of the M cells; and if the network device determines that all the data of the N to-be-scheduled terminals is delay-insensitive data, stopping, by the network device, sending the data in the second time domain unit of the M cells. determining, by a network device in a first time domain unit, whether data of N to-be-scheduled terminals in a second time domain unit in M cells of the network device is delay-sensitive data, wherein the M cells share a same remote radio unit, RRU; and if the network device determines that data of K to-be-scheduled terminals of the N to-be-scheduled terminals is delay-sensitive data, the K to-be-scheduled terminals are separately located in P cells of the M cells, and a power required for sending the delay-sensitive data in each of the P cells is less than or equal to a preset power threshold corresponding to the cell, sending, by the network device, the data of the K to-be-scheduled terminals in a second time domain unit of the P cells, wherein M, N, P, and K are integers greater than or equal to 1, K is less than or equal to N, and P is less than or equal to M; wherein the method further comprises: if the network device determines that a power required for sending the delay-sensitive data in a first cell of the P cells is greater than a preset power threshold corresponding to the first cell, sending, by the network device, the data of the N to-be-scheduled terminals in the second time domain unit of the M cells; and if the network device determines that all the data of the N to-be-scheduled terminals is delay-insensitive data, stopping, by the network device, sending the data in the second time domain unit of the M cells. if the network device determines that a power required for sending the delay-sensitive data in a first cell of the P cells is greater than a preset power threshold corresponding to the first cell, sending, by the network device, the data of the N to-be-scheduled terminals in the second time domain unit of the M cells; and if the network device determines that all the data of the N to-be-scheduled terminals is delay-insensitive data, stopping, by the network device, sending the data in the second time domain unit of the M cells. <EOS>
