Communication control method and device are provided. The method includes: determining M parts of resources for transmitting a control area in N parts of resources, wherein the N parts of resources are acquired by dividing, in a frequency domain, frequency resources of symbols for transmitting the control area in a s-TTI, M and N are integers, 1≤M≤N; and transmitting a PDCCH to a terminal through the control area. The method and device may realize communication control of the network to the terminal more flexibly and with less average resource overhead in the s-TTI technology.
