If 4) comparative quantity is CPICH path loss, TTI length is determined using in the following manner：

If the path loss that UE detects CPICH is less than or equal to TTI selection thresholdings, the first TTI length is selected；If the path loss that UE detects CPICH is more than or equal to the Τ Threshold value is selected, then selects the 2nd TTI length, wherein the first TTI length is less than the 2nd TTI length, such as the first TTI length is 10ms, and the 2nd TTI length is 20ms.

Path loss=.1.11 channel emission power-CPICH RSCP.

Such as path loss is more than 10dB, then UE selects 20ms TTI, otherwise selection 10ms TTL are it should be noted that described above " the first TTI length; and " the 2nd TTI length,, simply a kind of citing, it is also possible to there are more TTI length, that is the 3rd TTI length, the 4th TTI length etc., the present invention is not construed as limiting.

It is emphasized that, in the mode of any of the above determination TTI length, the number of TTI selection threshold values and the number of corresponding TTI length are simply illustrated by way of example, certainly, within the scope of the invention, by selecting threshold value and the comparative quantity to be compared TTI, the embodiment of the present invention can also select threshold value and corresponding TTI length to determine TTI length using the TTI of other numbers different from above number.

13rd, by the TTI Length Indications of selection to base station.

In this step, UE can be using indicating the TTI Length Indications information of TTI length by different modes by the TTI length signals base of selection.For example, can as described below by the use of TFCI as TTI Length Indications information by TTI Length Indications to base station, the TTI explicit indicators of an instruction TTI length can also be increased in special physical controlling channel of upward as described below（Τ Length Indication information）By TTI Length Indications to base station, so that base station parses the data in DPDCH channels according to indicated TTI length.

14th, dedicated channel data is sent to the base station according to the TTI length of selection.

It should be noted that, above-mentioned steps 13 and 14 can occur parallel, for example, if UE uses the TFCI in DPCCH to indicate the selected TTI length of UE, then step 13 and 14 can occur parallel, that is, UE transmits TFCI using DPCCH, and upstream data is sent with using DPDCH.Wherein, TFCI may be used to indicate the selected TTI length of UE and the selected transformats of UE.

In embodiments of the present invention, UE can only transmit a packet when the TTI length according to selection and the base station carry out data transmission within a DTX cycle, can also be at one Multiple packets are continuously transmitted in the DTX cycles.When UE only transmits a packet within a DTX cycle, if UE RLC Slow have data in depositing, RLC delivers a packet every the DTX cycles to MAC layer.When UE continuously transmits multiple packets within a DTX cycle, UE rlc layers can every selected TTI length to MAC layer deliver a packet.
