Description
Technical field
The present invention relates to the power control techniques field in mobile communication system, relate in particular to a kind of E-PUCH Poewr control method and system.
Background technology
High speed uplink packet access (HSUPA) technology is a kind of up enhanced scheme that third generation partner program version 6 (3GPPRelease 6) proposes.2008,3GPP Release 8 standards have been introduced cell forward access channel (CELL_FACH) state that strengthens, when terminal is in CELL_FACH state lower 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 accesses 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 state of LCR TDD system, network side and terminal adopt the scheduled transmission mode to realize transmitting uplink data by E-PUCH.Wherein, system can comprise main carrier and auxiliary carrier wave for the carrier wave that is used for transmitting uplink data of each terminal distribution, terminal is first set up with network side on main carrier and is communicated by letter, then can switch between each carrier wave (comprising main carrier and auxiliary carrier wave), thereby adopt suitable carrier wave and network side to carry out transmitting uplink data according to current demand.
Terminal on main carrier with network side set up communicate by letter complete before, terminal can only adopt common terminal sign (E-RNTI) and network side to establish a communications link, in process is set up in described communication connection, 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 knows that by this RRC Connection Setup message network side is dedicated H-RNTI and the special E-RNTI that this UE distributes, 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 communication connection.Wherein, step 101～103 are to complete 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 in step 105, UE switches to main carrier from main carrier, again for example in step 106 UE switch to main carrier from auxiliary carrier wave, in addition, UE also can switch between each auxiliary carrier wave.
In the HSUPA business, in order to reduce to send the interference that upstream data causes other residential quarter, the uplink transmission power of terminal need to be limited in up lifting with respect to thermal noise (RoT) resource allowed band, therefore need to 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 the parameters of uplink power control to UE broadcasting by the 5th system resource block message (SIB5), for example, " Common E-DCHsystem info " indication UE in SIB5 carries out the parameter that E-PUCH power is controlled 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 auxiliary carrier wave work, RNC can arrive certain auxiliary carrier wave by the RRC dedicated signaling with this terminal configuration in process is set up in the RRC connection so, provides simultaneously the parameter of the corresponding E-PUCH power control of this carrier wave, for example P with terminal configuration in the RNC decision
E-baseInitial value PRX
Des_baseDeng.In 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 the parameters that is used for the E-PUCH uplink power control and specifically how to have obtained, wherein, the E-PUCH initial power that different carrier is corresponding is generally different, but, carry out power control about specifically how using described parameter, prior art does not provide corresponding scheme, this will cause in terminal from using public E-RNTI to forward the use special E-RNTI to, perhaps terminal is in the situations such as intercarrier switching, the indefinite 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.

9. an E-PUCH power control system, is characterized in that, this system comprises terminal and base station;
Described terminal and base station, before the special E-RNTI that described terminal Adoption Network side is distributed sends upstream data by E-PUCH to network side, all according to configuration or the current uplink transmission power value of E-PUCH of network side, the uplink transmission power value of described E-PUCH of resetting, and on the basis of replacement value, adopt same procedure to adjust the uplink transmission power of E-PUCH;
Wherein, when terminal finishes at the available scheduling window that adopts public E-RNTI, when perhaps the available scheduling window end of the public E-RNTI of terminal employing and terminal obtain described special E-RNTI, when perhaps terminal adopts described special E-RNTI to send scheduling request information by E-RUCCH to network side first, perhaps terminal adopts described special E-RNTI to send dispatch request by E-RUCCH to network side first, and when receiving the dispatching command that network side sends by E-AGCH, the uplink transmission power value of described E-PUCH of resetting;
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 for reshuffling 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 described E-PUCH of resetting.
10. system as claimed in claim 9, is characterized in that,
Described terminal, before the special E-RNTI that the Adoption Network side is distributed sends upstream data by E-PUCH to network side, adopt public E-RNTI to send upstream data by E-PUCH to network side, and, when adopting public E-RNTI to send upstream data by E-PUCH to network side, terminal is defined as power initial value in 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 PHYSICAL SHARED CHANNELRECONFIGURATION REQUEST message, adjusts the uplink transmission power of E-PUCH in the available scheduling window of described public E-RNTI.
