Description
Technical field
The present invention relates to the power control techniques field in the mobile communication system, relate in particular to a kind of E-PUCH Poewr control method and system.
Background technology
It is a kind of up enhanced scheme that third generation partner program version 6 (3GPPRelease 6) proposes that high speed uplink packet inserts (HSUPA) technology.2008,3GPP Release 8 standards have been introduced cell forward access channel (CELL_FACH) state that strengthens, when terminal is in CELL_FACH state following time, base station and terminal employing high speed downlink packet access (HSDPA) technology and HSUPA technical transmission up-downgoing data.
In low spreading rate time division duplex (LCR TDD) system, the channel architecture of HSUPA business comprises two up channels and two down channels, up channel wherein comprises that strengthening dedicated channel E-DCH inserts ascending control channel (E-DCH Random access Uplink ControlChannel at random, E-RUCCH) and E-DCH physical uplink channel (E-DCH Physical UplinkChannel, E-PUCH), down channel comprises E-DCH absolute grant channel (E-DCH AbsoluteGrant Channel, E-AGCH) and E-DCH HARQ just answer indicating channel (E-DCH HARQIndicator Channel, E-HICH).
Under the enhancing CELL-FACH of LCR TDD system state, network side and terminal adopt the scheduled transmission mode to realize transmitting uplink data by E-PUCH.Wherein, system can comprise main carrier and auxilliary carrier wave for the carrier wave that is used for transmitting uplink data of each terminal distribution, terminal is communicated by letter with network side foundation on main carrier earlier, can between each carrier wave (comprising main carrier and auxilliary carrier wave), switch then, thereby adopt suitable carrier wave and network side to carry out transmitting uplink data according to current demand.
Terminal on the main carrier with network side set up communicate by letter finish before, terminal can only adopt common terminal sign (E-RNTI) and network side to establish a communications link, communicate to connect in the process of foundation described, network side is the terminal distribution special E-RNTI, after this, terminal adopts this special E-RNTI and network side to carry out transmitting uplink data.
Fig. 1 is the schematic diagram that strengthens LCR TDD system uplink data transmission procedure under the CELL-FACH state, and as shown in Figure 1, this process comprises:
In this step, UE is known dedicated H-RNTI and the special E-RNTI that network side distributes for this UE by this RRC Connection Setup message, and after this, UE adopts dedicated H-RNTI and special E-RNTI and network side to communicate.
By above-mentioned steps 101～step 104, UE and network side have been set up and have been communicated to connect.Wherein, step 101～103 are to finish on the main carrier that distributes of UE in system.
After UE and network side establish a communications link, can be according to current needs, reshuffle or radio bearer the RRC signaling such as is reshuffled and is configured to and carries out transmitting uplink data on other carrier waves by physical channel, for example UE switches to main carrier from main carrier in the step 105, again for example in the step 106 UE switch to main carrier from auxilliary carrier wave, in addition, UE also can switch between each auxilliary carrier wave.
In the HSUPA business, in order to reduce to send the interference that upstream data causes other sub-district, the uplink transmission power of terminal need be limited in up lifting (RoT) the resource allowed band with respect to thermal noise, therefore need control the E-PUCH uplink transmission power of terminal, thereby improve the data transmission rate of terminal, enlarge power system capacity.
At present, in the TS25.331 technical standard, network side is used for each parameter of uplink power control to UE broadcasting by the 5th system resource block message (SIB5), for example, the parameter that " Common E-DCHsystem info " indication UE among the SIB5 carries out the control of E-PUCH power when being operated in main carrier comprises P
E-baseInitial value PRX
Des_base, parameter ' Pebase power control gap ' and ' TPC step size '.If in auxilliary carrier wave work, RNC can set up in the process in the RRC connection and by the RRC dedicated signaling this terminal configuration be arrived certain auxilliary carrier wave so, provides the parameter of the corresponding E-PUCH power control of this carrier wave simultaneously, for example P with terminal configuration in the RNC decision
E-baseInitial value PRX
Des_baseDeng.In the corresponding TS25.433 technical standard, corresponding E-PUCH power control parameters when RNC has provided base station side and is operated in each carrier wave in Physical Shared Channel reconfiguration request (PHYSICAL SHAREDCHANNEL RECONFIGURATION REQUEST) message, for example: ' PRX
Des_basePer UARFCN ', ' E-PUCH Power Control GAP ' and ' E-PUCH TPC Step Size '.
As seen, prior art has provided each parameter that is used for the E-PUCH uplink power control and specifically how to have obtained, wherein, the E-PUCH initial power of different carrier correspondence is generally different, but, carry out power control about specifically how using described parameter, prior art does not provide corresponding scheme, this will cause forwarding the use special E-RNTI in terminal to from using public E-RNTI, perhaps terminal is under situations such as intercarrier switching, the indeterminate power that specifically how to carry out of end side and base station side is controlled, perhaps obtain different E-PUCH ascending power values, thereby further cause uplink interference to increase or the base station can not be well to problems such as up RoT resource manage.
Summary of the invention
In view of this, the purpose of the embodiment of the invention is to provide a kind of E-PUCH Poewr control method and system, makes how end side and base station side clearly specifically carry out power control.

When the base station adopts the available scheduling window of public E-RNTI to finish in terminal, perhaps the base station receive FP frame indication network side that RNC sends for terminal distribution during special E-RNTI, perhaps the base station receives that RNC sends when being used to reshuffle the FP frame of E-PUCH power contorl parameters, perhaps the base station adopts the available scheduling window of public E-RNTI to finish in terminal, and when the dispatch request that the base station adopts described special E-RNTI to send to network side by E-RUCCH according to terminal is dispatched described terminal first, the uplink transmission power value of the described E-PUCH that resets.
14. system as claimed in claim 12 is characterized in that,
Described terminal, the special E-RNTI that adopts network side to distribute by E-PUCH before network side sends upstream data, adopt public E-RNTI to send upstream data to network side by E-PUCH, and, adopt public E-RNTI by E-PUCH when network side sends upstream data, terminal is defined as power initial value among the SIB5 with the initial gain value of E-PUCH, adjusts the uplink transmission power of E-PUCH in the available scheduling window of described public E-RNTI;
Described base station, when scheduling first adopts public E-RNTI to send the terminal of upstream data, the initial gain value of E-PUCH is defined as initial gain value in the PHYSICAL SHARED CHANNELRECONFIGURATION REQUEST message, in the available scheduling window of described public E-RNTI, adjusts the uplink transmission power of E-PUCH.
