A method for distributing and scheduling wireless resources in an orthogonal frequency division multiplexing system, the method comprising: a network side defining at least one short resource unit, wherein the short resource unit is less than a Resource Block, RB; the network side selecting a short resource unit, wherein the network side selecting the short resource unit specifically comprises: the network side selecting one short resource unit according to Quality of Service, QoS, requirement and a wireless channel state of a User Equipment, UE; and the network side allocating the wireless resources for the User Equipment, UE, according to the selected short resource unit, and informing the UE of scheduling information of the wireless resources, wherein defining the short resource unit specifically comprises: the network side defining a minimum resource allocation granularity as that a frequency domain width is 12 sub-carriers and a time domain width is one symbol; when used for an uplink wireless resource allocation, the symbol is a Single Carrier-Frequency Division Multiplex Access, SC-FDMA, symbol; when used for a downlink wireless resource allocation, the symbol is an Orthogonal Frequency Division Multiplexing, OFDM, symbol; the short resource unit is a multiple of the minimum resource allocation granularity, wherein when the system uses a normal Cyclic Prefix, CP, a value of the multiple is 1 to 13; when the system uses an extended CP, a value of the multiple is 1 to 11. a network side defining at least one short resource unit, wherein the short resource unit is less than a Resource Block, RB; the network side selecting a short resource unit, wherein the network side selecting the short resource unit specifically comprises: the network side selecting one short resource unit according to Quality of Service, QoS, requirement and a wireless channel state of a User Equipment, UE; and the network side allocating the wireless resources for the User Equipment, UE, according to the selected short resource unit, and informing the UE of scheduling information of the wireless resources, wherein defining the short resource unit specifically comprises: the network side defining a minimum resource allocation granularity as that a frequency domain width is 12 sub-carriers and a time domain width is one symbol; when used for an uplink wireless resource allocation, the symbol is a Single Carrier-Frequency Division Multiplex Access, SC-FDMA, symbol; when used for a downlink wireless resource allocation, the symbol is an Orthogonal Frequency Division Multiplexing, OFDM, symbol; the short resource unit is a multiple of the minimum resource allocation granularity, wherein when the system uses a normal Cyclic Prefix, CP, a value of the multiple is 1 to 13; when the system uses an extended CP, a value of the multiple is 1 to 11. the network side defining a minimum resource allocation granularity as that a frequency domain width is 12 sub-carriers and a time domain width is one symbol; when used for an uplink wireless resource allocation, the symbol is a Single Carrier-Frequency Division Multiplex Access, SC-FDMA, symbol; when used for a downlink wireless resource allocation, the symbol is an Orthogonal Frequency Division Multiplexing, OFDM, symbol; the short resource unit is a multiple of the minimum resource allocation granularity, wherein when the system uses a normal Cyclic Prefix, CP, a value of the multiple is 1 to 13; when the system uses an extended CP, a value of the multiple is 1 to 11.
