Description

The merging method and the terminal of transmission power control command
Technical field
The present invention relates to universal mobile telecommunications system wireless access network (UMTS radio access network, hereinafter to be referred as: high speed downlink packet UTRAN) inserts (High Speed Downlink PacketAccess, hereinafter to be referred as: HSDPA) technology, especially a kind of transmission power control command (Transmitpower control, hereinafter to be referred as: merging method TPC) and terminal (User Equipment, hereinafter to be referred as: UE).
Background technology
It is sudden that the business characteristic of wireless communication packets business is that the transmission of its data has, that is: grouped data is interrupted the transmission.In once complete business procedure, the interrupted number of times of data may be very many.For example: in the web page browsing business, generally, have the download webpage of transfer of data and the browsing page of free of data transmission to hocket; In addition, need for a long time fragmentary transfer of data in some business in addition.In business once,, all keep same connection status if no matter have or not transfer of data, that is: when not having transfer of data, also, then Internet resources can be wasted, and simultaneously online number of users can be therefore limited according to there being the transfer of data situation to distribute the Internet resources of as much; But, if connect when when transfer of data is arranged, beginning, connect and when this transfer of data stops, discharging, then because transfer of data sudden, the foundation that needs are frequent is connected with release, this can increase the load of system's control connection state again, and can increase data transmission delay, business that can't requirement of real time.
At present, the principal element of the simultaneously online number of users of restriction is a uplink interference.According to existing Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, hereinafter to be referred as: WCDMA) agreement, when UE and network side are set up cell private channel (CELL_Dedicated Channel, hereinafter to be referred as: CELL_DCH), be in the CELL_DCH connection status, no matter it has or not packet data transmission, capital and base station (hereinafter to be referred as: carry out special physical controlling channel of upward (Dedicated Physical Control Channel Node B), hereinafter to be referred as: DPCCH) transmission, will bring uplink interference to other online user like this, thereby limit the number of users of online connection status.
In order to reduce uplink interference, increase simultaneously online number of users, third generation partner program (3rdGeneration Partnership Project, hereinafter to be referred as: 3GPP) in the 28th meeting of RAN by having set up the project that forever works online, its target is to be in the non-activation moments that does not have data to send between UE and UTRAN, makes UE can remain on the CELL_DCH connection status for a long time, few again simultaneously resource of eating dishes without rice or wine that consumes, and the business recovery time is less than 50ms.In order to realize this target, 3GPP the 7th edition (hereinafter to be referred as: in version R7), be in the non-activation moments or the inactive moment of transfer of data between UE and UTRAN, DPCCH adopts discontinuous transmission, and (DiscontinuousTransmission is hereinafter to be referred as DTX) pattern.In addition, in order to make the UE power saving, UE can adopt discontinuous reception (Discontinuous Reception according to the parameter of UTRAN configuration, hereinafter to be referred as: DRX) pattern, this DTX between UTRAN and UE and DRX pattern are called continuous grouping and are connected that (Continuous Packet Connectivity is hereinafter to be referred as CPC) pattern.UE can be provided with a discontinuous transmission and accepting state (Discontinuous Transmission_DiscontinuousReception_STATUS, hereinafter to be referred as: DTX_DRX_STATUS) variable identifies it and whether is in reflection CPC pattern.When UE is in the CELL-DCH state; And the variable high speed descending sharing channel receives (HighSpeed Downlink Shared Channel RECEPTION, hereinafter to be referred as: HS_DSCH_RECEPTION) variable and the transmission of enhancing dedicated channel (Enhanced DedicatedChannel_TRANSMISSION, hereinafter to be referred as: E_DCH_TRANSMISSION) value of variable is True; And do not dispose the DCH transmission channel; And the discontinuous transmission that has been provided for storing the parameter configuration relevant with the CPC pattern with receive parametric variable (DiscontinuousTransmission_Discontinuous Reception__PARAMS, hereinafter to be referred as: DTX_DRX_PARAMS); And when UE received the parameter configuration relevant with the CPC pattern " the DTX-DRX timing information " information unit that network side sends, the value that UE is provided with DTX_DRX_STATUS was True, represented that UE is current to be under the CPC pattern, can carry out DTX and DRX.
After the value of DTX_DRX_STATUS is True, up DPCCH and descender DPCH (Fractional-Dedicated Physical Control Channel, hereinafter to be referred as: F-DPCH) can continue to postpone transmission continuously in the radio frames, afterwards, UE is with discontinuous transmission and receiving mode variable (Discontinuous Transmission_Discontinuous Reception_mode, hereinafter to be referred as: value DTX_DRX_mode) is set to 1, that is: DTX_DRX_mode=1.After the transmission of DTX_DRX_mode=1 and upstream discontinuous is activated by Node B, the terminal just value of up link discontinuous transmission mode (UP Link_Discontinuous Transmission_mode) is set to 1, that is: UL_DTX_mode=1, the transmission of beginning upstream discontinuous, otherwise UL_DTX_mode=0.Equally, when DTX_DRX_mode=1 and downlink discontinuous receive activated by Node B after, DL_DRX_mode=1, the beginning downlink discontinuous receives, otherwise DL_DRX_mode=0.
When UE carries out soft handover, Node B with a plurality of sub-districts sets up Radio Link (RadioLink simultaneously, hereinafter to be referred as: RL), all Node B that set up RL with UE belong to the Active Set of UE, all Radio Links that belong to same Node B constitute a Radio Link collection (Radio Link Set, hereinafter to be referred as: RLS).When carrying out DTX in the process of UE at soft handover, following two kinds of situations can appear:
First kind of situation:
The value of DTX_DRX_STATUS is True, and DTX_DRX_mode=1.At this moment, have only the Node B of the service HS_DSCH sub-district of UE can be by shared control channel (the Shared Control Channel for HS-DSCH of layer 1 HS-DSCH, hereinafter to be referred as: the HS-SCCH) value of order control UL_DTX_mode and DL_DRX_mode, the Node B of non-service HS_DSCH sub-district can't be known the control of the Node B of service HS_DSCH sub-district to the UL_DTX_mode value, thereby can't know the current DTX pattern that whether is in of UE, can't know the DPCCH transmission time.At this moment, the Node B of non-service HS_DSCH sub-district is defaulted as UL_DTX_mode=1, that is: think and just detect DPCCH at DTX pattern place by the current DTX of the being in state of UE, produces corresponding TPC and is transferred to UE by descending F-DPCH.The UL_DTX_mode value of the Node B acquiescence of non-service HS_DSCH sub-district may be inconsistent with the actual value of UL_DTX_mode.
Second kind of situation:
UL_DTX_mode=1, the discontinuous transmission of up DPCCH is defined as: in a time slot, below satisfying during any one condition, UE carries out up DPCCH transmission in this time slot: 1, High-Speed Dedicated Physical Control Channel (HighSpeed Dedicated Physical Control Channel, hereinafter to be referred as: HS-DPCCH) going up transmission has and mixes automatic repeat requests and confirm that (Hybrid Automatic RePeatRequest ACK is hereinafter to be referred as HARQ-ACK) information; 2, HS-DPCCH last transmission has CQI, and (Channel Qual-ity Indicator is hereinafter to be referred as CQI) information; 3, in this time slot, have upstream data by strengthen dedicated channel (Enhanced Dedicated Channel, hereinafter to be referred as: E-DCH) transmission; 4, this time slot belongs to the time slot of up DPCCH transmission pattern definition; 5, leading (preamble) that this time slot has a up DPCCH with after lead (postamble) transmission.Wherein, condition 1 and the situation of condition 2 for the up HS-DPCCH of transmission need transmission DPCCH, owing to have only the Node B HS-DPCCH of service HS_DSCH sub-district and the transmission time of corresponding D PCCH,, the Node B of non-service HS_DSCH sub-district can't be known; And all Node B can be known the transmission of 3,4,5 times DPCCH of condition in the Active Set.
The condition of first kind of situation and second kind of situation 1,2 times,, thereby also just can't correctly detect up DPCCH, generation and to UE transmission TPC because the Node B of non-service HS_DSCH sub-district can't be known the transmission time of up DPCCH in the Active Set; And the condition of second kind of situation 3,4,5 times, all Node B can be known the transmission of up DPCCH in the Active Set, that is: the Node B of non-service HS_DSCH sub-district preamble and the postamble time slot when the up DPCCH DTX transmission pattern time slot that is provided with, up E-DCH transmission, following the up DPCCH time slot of transmission and send up DPCCH, can detect the up DPCCH that UE sends, and send TPC by descending F-DPCH to UE in corresponding time slot.The up DPCCH transmission time slot that can know at the NodeB of above-mentioned non-service HS_DSCH sub-district, UE merge send from all RLS in the Active Set with the corresponding descending F-DPCH of up DPCCH sending time slots in the TPC order of carrying, otherwise UE only merge that the RLS of service HS_DSCH sub-district sends with the corresponding descending F-DPCH of up DPCCH sending time slots in the TPC order of carrying, and the TPC that ignores other RLS orders, no longer with non-corresponding TPC participation merging of serving the Node B transmission of HS_DSCH sub-district.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art:
When UE carries out soft handover under the CPC pattern, in the above two kinds of cases, the complete nonjoinder of UE is from the TPC of the Node B transmission of non-service HS_DSCH sub-district, even the Node B in non-service HS_DSCH sub-district can be known corresponding up DPCCH transmission time slot, generation TPC also sends to by descending F-DPCH under the situation of UE, also nonjoinder is from the TPC of the NodeB transmission of non-service HS_DSCH sub-district, the TPC that does not make full use of annexable other sub-district participates in power control, thereby make uplink power control not accurate enough, may increase interference other sub-district.
