It addition, the terms "and/or", being only a kind of incidence relation describing affiliated partner, can there are three kinds of relations in expression, for instance, A and/or B, it is possible to represent: individualism A, there is A and B, individualism B these three situation simultaneously。It addition, character "/" herein, typically represent forward-backward correlation to as if the relation of a kind of "or"。
The schematic flow sheet of the TTI indicating means that Fig. 1 provides for one embodiment of the invention, as it is shown in figure 1, the TTI indicating means of the present embodiment can be as described below。
101, UE selects or determines the TTI used when strengthening uplink。
Such as: UE according to leading initial power (Preamble_Initial_Power), can select or determine the TTI that the up common E-DCH resource of acquisition is corresponding。Wherein, leading initial power can be obtained by following formula:
Preamble_Initial_Power=PrimaryCPICHTXPower-CPICH_RSCP+UL Interference+ConstantValue；
Wherein, Primary Common Pilot Channel transmitting power (PrimaryCPICHTXPower), steady state value (ConstantValue) can obtain from system information block type 5 (SIB5)；Uplink interference (ULInterference) can obtain from system information block type 7 (SIB7)；CPICH Common Pilot Channel received signal code power (CPICH_RSCP) can be obtained by measuring by UE。
As Preamble_Initial_Power=a, UE according to making an appointment, can select or determine that TTI is 10ms, i.e. 10msTTI, or select or determine that TTI is 2ms, i.e. 2msTTI；
As Preamble_Initial_Power > a, represent that UE dump power is low, then UE can select or determine that TTI is 10ms, i.e. 10msTTI；
As Preamble_Initial_Power < a, represent that UE dump power is high, then UE can select or determine that TTI is 2ms, i.e. 2msTTI。
Wherein, a is the power threshold set, and is a constant, and this power threshold specifically can be arranged on UE by base station control device by broadcast or proprietary signaling etc.。
Again such as: UE according to path loss, can also select or determine the TTI that the up common E-DCH resource of acquisition is corresponding。
Path loss=PrimaryCPICHTxPower-CPICHRSCP；
Wherein, PrimaryCPICHTXpower can obtain from SIB5；CPICH_RSCP can be obtained by measuring by UE。
As path loss=b, UE according to making an appointment, can select or determine that TTI is 10ms, i.e. 10msTTI, or select or determine that TTI is 2ms, i.e. 2msTTI；
As path loss > b, represent the up channel condition poor (such as: UE distance NodeB is remote) of UE to NodeB, then UE can select or determine that TTI is 10ms, i.e. 10msTTI；
As path loss < b, represent the up channel condition good (such as: UE distance NodeB is near) of UE to NodeB, then UE can select or determine that TTI is 2ms, i.e. 2msTTI。
Wherein, b is the threshold value set, and is a constant, and this threshold value specifically can be arranged on UE by base station control device by broadcast or proprietary signaling etc.。
It is to be understood that UE can also adopt additive method, selecting or determine the TTI that the up common E-DCH resource of acquisition is corresponding, this is not defined by the present embodiment。
102, above-mentioned UE utilizes up common E-DCH resource and the TTI being pre-configured with, to the TTI that NodeB instruction selects or determines。
Wherein, UE obtains up common E-DCH resource。
Wherein, UE can adopt various ways to obtain the TTI being pre-configured with, for instance: UE can pass through system broadcast message, it is thus achieved that the TTI being pre-configured with；Or can also by special control logic channel (i.e. proprietary signaling), it is thus achieved that the TTI being pre-configured with；Or the regulation in agreement can also be passed through, it is thus achieved that the TTI being pre-configured with, this is not defined by the present embodiment。
Such as, UE can utilize up common E-DCH resource and the TTI being pre-configured with, by the E-DCH medium education (ImprovedMediaAccessControlforE-DCH strengthened, it is called for short MAC-i) the MAC-iPDU head of Packet Data Unit (PacketDataUnit, the be called for short PDU) TTI that selects to NodeB instruction or determine。
Such as: UE can utilize up common E-DCH resource and the TTI being pre-configured with, by the TTI that logic channel (LogicChannel the is called for short LCH) mark (LCH-ID) in the MAC-iPDU head of MAC-iPDU and/or the bit in spare bits (totally 4 bit) select to NodeB instruction or determine。
Such as: the special identifier of the LCH-ID in MAC-iPDU head (in 0000～1111 any two) represents the UE TTI selecting or determining, illustrates: 0000 can represent 2msTTI；0001 can represent 10msTTI, and vice versa。
Again such as: the bit (bit except 0000) in the spare bits in MAC-iPDU head represents the UE TTI selecting or determining, illustrates: 0001 can represent 2msTTI；0010 can represent 10msTTI, and vice versa。
Again such as: 4 bits (bit except 0000) in the special identifier (any one in 0000～1111) of the LCH-ID in MAC-iPDU head and spare bits, represent the UE TTI selecting or determining, illustrate:
