Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of implementation method, system and device of high speed uplink packet access (HSUPA) business.
Background technology
HSUPA (High Speed Uplink Packet Access, the high speed uplink packet access) technology is 3GPP (3rd Generation Partnership Project, third generation partner program) a kind of up enhanced scheme that proposes, the channel architecture of HSUPA business comprises two up channels and two down channels, wherein, two up channels are respectively E-RUCCH (E-DCH Random access Uplink ControlChannel, E-DCH uplink random access control channel) and E-PUCH (E-DCH PhysicalUplink Channel, E-DCH physical uplink link channel), two down channels are respectively E-AGCH (E-DCH Absolute Grant Channel, the E-DCH absolute grant channel) and E-HICH (E-DCHHARQ Indicator Channel, E-DCH HARQ confirms indicating channel).
At the CELL-FACH of HSUPA business (Forward Access Channel, forward access channel) during state strengthens, if UE has data to need to send, then by E-RUCCH to NodeB (base station) reporting scheduling information, the schedule information that NodeB reports according to UE determines whether to allow this UE to send upstream data, if allow this UE to send upstream data, then notify this UE with relevant scheduling resource information distribution at E-AGCH, UE adopts corresponding transmitted power P at the corresponding physical resource of E-PUCH subsequently
E-PUCHSend data, after NodeB receives data and demodulating and decoding, ACK/NACK message is fed back to UE at E-HICH, shown in concrete interaction flow Fig. 1.
In the said process, the scheduling resource information that NodeB sends at E-AGCH is by itself and the common closed loop numerical value P that safeguards of UE
E-baseDetermine, and UE sends the transmitted power P that data adopt at E-PUCH
E-PUCHAlso by P
E-baseDetermine, therefore, the P that NodeB and UE safeguard
E-baseNeed to be consistent, particularly, adjust P by TPC (Transmitter Power Control, through-put power control) closed loop
E-baseIf, and surpass setting thresholding GAP for the timer that scheduling interval is carried out timing among NodeB and the UE, then NodeB and UE need the P that initialization is safeguarded separately
E-base
In the CELL-FACH state strengthened, professional characteristics were sudden more intense, and the interval of transfer of data is larger, may reach second interval of level.If in the past communicating requirement equally by dispatch terminal frequently to keep uplink synchronous, then in the situation that terminal does not have transfer of data can cause the serious waste of resource, so in the CELL-FACH state strengthens, if terminal does not have data to send, then terminal is not carried out any scheduling, namely allow the terminal step-out, thereby saved resource, but at P
E-baseThere are the following problems in the aspect of safeguarding:
Allow the terminal step-out so that NodeB may be very large to the scheduling interval of UE, set thresholding GAP, P if this interval exceeds
E-baseJust need to carry out initialization.At NodeB and UE respectively in the process to the scheduling interval timing, if UE does not correctly receive the scheduling resource information that NodeB sends, then UE thinks that NodeB does not dispatch oneself, the timer of UE end statistics scheduling interval continues timing, and NodeB end is after sending scheduling resource information to UE on the E-AGCH, the timer initialization of statistics scheduling interval, thus the timer of UE end surpasses first GAP thresholding, the P that causes NodeB and UE to safeguard separately than the timer that NodeB holds
E-baseInconsistent, so, when dispatching next time, after UE receives the scheduling resource information of Node transmission, according to the P of its maintenance
E-baseBe identified for sending the transmitted power of upstream data, and adopt this transmitted power to send data at E-PUCH, and by front described, owing to there being the P that safeguards among UE and the NodeB
E-baseInconsistent situation, therefore, the transmitted power of the transmitted power that UE adopts when sending data and NodeB expection is inconsistent, and is excessive, then excessive to other users' of system interference if UE sends the transmitted power of the data; If it is too small that UE sends the transmitted power of the data, then NodeB can not receive the data that UE sends exactly, and then affects the demodulation of data and decoding etc., can't guarantee the performance of system.
