Background technology

In a wireless communication system, downlink transfer refers to the process of send a signal to user equipment by base station.Downstream signal Data-signal and control signal are generally included.HSDPA (High Speed Downlink Packet Access, high-speed downstream Link packet is accessed) it is a kind of packet-based data, services, it can strengthen message transmission rate during downlink transfer. HSDPA technologies can apply to WCDMA (Wideband Code Division Multiple Access, WCDMA) In system, in a wcdma system, base station is normally referred to as Node B (Base station, B node), and user equipment is in other words Mobile terminal is normally referred to as UE (user Equipment, user equipment).It is divided into the range of usual NodeB coverings At least one cell is provided on 3 or 6 sectors, each sector.

In order to realize HSDPA functional characteristic, HSDPA introduces three kinds of new channels in physical layer specification：HS- PDSCH (High-Speed Downlink Packet Access, high-speed down link shares physical channel), HS-SCCH (High-Speed Shared Control Channel, High-Speed Shared Control Channel) and HS-DPCCH (Uplink High- Speed Dedicated Physical Control Channel, up-link High-Speed Dedicated Physical Control Channel).It is simple next Say, on the one hand, cell sends the data-signal in downstream signal to UE using HS-PDSCH channels, while utilizing HS-SCCH Channel to send the control signal in downstream signal to UE, and the control signal can be used for demodulation decoding of data-signal etc. and use On the way；On the other hand, UE is after data-signal is received, corresponding data signal is demodulated and decoded according to control signal etc. Reason, then feeds back HARQ-ACK information (the Hybrid Automatic for characterizing reception condition using HS-DPCCH channels to cell Repeat Request-ACK, hybrid automatic repeat-request confirmation), HARQ-ACK information can be ACK/NACK/DTX letters Breath, wherein, ACK characterizes UE and proper reception of data-signal, and NACK characterizes UE and fails to be properly received data-signal, and DTX characterizes UE Do not detect data or cell and be in deactivation status etc., one of key technology used in this process namely HSDPA： HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request).

But it is able to further improve message transmission rate during downlink transfer, also wants to introduce in the prior art Multicarrier/multiple cell technology and multiple stream transmission technology.Multicarrier/multiple cell technology introduces serving cell and assistant service cell Concept so that a UE can use two that the cell of two (herein by taking two cells as an example) or more is provided simultaneously HSDPA carrys out cooperative transmission downstream signal, further strengthens message transmission rate during downlink transfer.Meanwhile, UE can be utilized The HS-DPCCH channel that serving cell is provided enters in a time slot simultaneously to both serving cell and assistant service cell The joint feedback of row HARQ-ACK information.Multiple stream transmission technology can then regard the extension of multicarrier/multiple cell technology as, maximum Difference be multicarrier/multiple cell technology need serving cell and assistant service cell have identical covering and identical under Row channel timing relationship, and multiple stream transmission technology does not need serving cell and assistant service cell that there is identical down channel to determine When relation.Multiple stream transmission technology is also referred to as Multiflow Transmission, abbreviation MF-Tx.

Serving cell and assistant service cell are in various embodiments, it is also possible to be referred to as main serving cell/auxiliary service Cell, main plot/secondary cell, by assisted cell/assisted cell etc..In multicarrier/multiple cell technology, carried on serving cell HS-SCCH channels, HS-PDSCH channels, HS-DPCCH channels, CPICH channels (Common Pilot Channel, public guide frequency Channel) channel and other dedicated channels, and assistant service cell only carries HS-SCCH channels, HS-PDSCH channels is used for HSDPA Data transfer and CPICH channels are used for channel estimation and measurement etc..UE is using two of serving cell and assistant service cell During HS-PDSCH channel cooperative data transmission signals, all using a HS-DPCCH channel in serving cell come feedback reception feelings Condition.When the down channel timing of serving cell and assistant service cell is identical, it is only necessary to which UE is by serving cell and assistant service The HARQ-ACK information consolidations that subframe is matched in cell are encoded in same time slot, then utilize the HS- in serving cell DPCCH channels feed back, the HS-DPCCH letters that serving cell and assistant service cell can simultaneously in analysis service cell Same HARQ-ACK information in road gets the feedback information each needed.And if during using multiple stream transmission technology, Namely if when the down channel timing relationship of serving cell and assistant service cell is differed, can be implemented using the present invention Timing method that example is provided and timing feedback method come solve down channel timing it is different caused by timing problems.

Embodiment one

Fig. 3 is refer to, the method flow diagram of the timing method provided it illustrates the embodiment of the present invention one.The timing method It can be used in the communication system shown in Fig. 2A or Fig. 2 B, the communication system can include different small of two down channels timing Area, two cells carry out downlink transfer using high-speed downlink packet access.Certainly, those skilled in the art may be easy to Think and, the timing method can be used for the scene such as dual-carrier double cell and the cell of dual carrier four.The timing method can be with Including：

Step 302, timing reference information is sent from management node to mobile terminal；

Management node can be RNC, before downlink data transmission, and management node can send timing reference information to UE, The timing reference information generally includes the identification information as timing reference cell in both of the aforesaid cell, and the identification information can To be cell sequence number, cell sequence number is nonnegative integer.

Step 304, mobile terminal knows that one in two cells is timing reference cell according to timing reference information；

UE can know that one in two cells is timing reference cell according to the timing reference information received, separately One is paired plot.Such as, the identification information in timing reference information is the cell sequence number of serving cell, then UE is known that Serving cell is timing reference cell, and assistant service cell is paired plot.

Step 306, mobile terminal receives the pairing subframe of two cells, and the subframe in timing reference cell is received Afterwards, again by feeding back hybrid automatic repeat-request confirmation, hybrid automatic repeat-request confirmation during predetermined time slot length For the hybrid automatic repeat-request confirmation of joint feedback is carried out to the pairing subframe in two cells simultaneously.

UE can receive the pairing subframe that two cells are sent by down channel, namely downstream signal.Make simultaneously in UE During with serving cell and two HS-PDSCH channel cooperative transmission downstream signals of assistant service cell, in the HS- of serving cell The subframe transmitted in PDSCH channels can be with another subframe transmitted in the HS-PDSCH channels of assistant service cell each other Match the relation of subframe.If serving cell is identical with the descending timing of assistant service cell, the two subframes should be sent out simultaneously UE sides are sent to, if the descending timing of serving cell and assistant service cell is differed, the two subframes typically will not be simultaneously UE sides are sent to, namely a subframe can first be sent to UE sides, and another pairing subframe can be delayed at one section and be sent to UE Side.UE is needed after the subframe in receiving timing reference cell, again by feeding back HARQ-ACK information during predetermined time slot length, The HARQ-ACK information is simultaneously to the HARQ-ACK information of the pairing subframe progress joint feedback in two cells.

In summary, the timing method that the present embodiment one is provided passes through true in the different cell of two down channel timings Fixed one of cell is timing reference cell, and the technology hand of HARQ-ACK information is fed back on the basis of the timing reference cell Section, is solved UE and is joined two parts of HARQ-ACK information of serving cell and assistant service cell using same HS-DPCCH Close the timing problems faced during feedback, the technology hand for being compressed or extending with reference to the processing time to UE sides and Node B sides Section, has reached the effect for alloing UE to use multiple stream transmission technology in the different cell of two down channel timings.

Embodiment two

In order to determine that one of them is timing reference cell from two cells, Fig. 4 is refer to, it illustrates of the invention real A kind of timing reference for applying the offer of example two determines method, and it is logical shown in Fig. 2A or Fig. 2 B that the timing reference determines that method can be used for In letter system, the communication system can include two different cells of down channel timing, and two cells use high-speed downstream Link packet access carries out downlink transfer.Certainly, those skilled in the art may be easy to think and, the timing reference determination side Method can be used for the scene such as dual-carrier double cell and the cell of dual carrier four.The timing reference determines that method can include：

Step 402, determined according to the time context for two subframes matched each other in two cells in two cells Advanced cell and delayed cell；

In UE simultaneously using serving cell and two HS-PDSCH channel cooperative data transmission signals of assistant service cell When, the subframe transmitted in the HS-PDSCH channels of serving cell can be with biography in the HS-PDSCH channels of assistant service cell Another defeated subframe matches the relation of subframe each other., can be by the time according to the precedence relationship of the two subframes in time Cell definitions residing for upper forward subframe are advanced cell, and the cell definitions residing for the subframe on the time rearward are delayed small Area.

Step 404, determined according to the dispatching cycle of the hybrid automatic repeat request process of advanced cell advanced cell and One in delayed cell is timing reference cell, and another is paired plot.

The dispatching cycle of HARQ processes is it is to be understood that cell transmits the data-signal of certain process in HS-PDSCH channels A subframe start, to the duration that is undergone of process of the next subframe for the data-signal for continuing to transmit the process.Typically For, the dispatching cycles of HARQ processes can be any one in 6 subframe durations, 7 subframe durations and 8 subframe durations, Mei Ge little (unless RNC is reconfigured) that the dispatching cycle for the HARQ processes that area is used is usually fixed, advanced cell and delayed The dispatching cycle for the HARQ processes that cell is used can be different.Can be with according to the dispatching cycle of the HARQ processes of advanced cell It is determined that one in advanced cell and delayed cell is timing reference cell, another is paired plot.It is determined that when, Ke Yigen Selected according to pre-defined strategy, the pre-defined strategy can be：If the scheduling week of the HARQ processes of advanced cell Phase is 6 subframe durations, it is determined that advanced cell is timing reference cell, and delayed cell is paired plot；If advanced cell The dispatching cycle of HARQ processes is 7 subframe durations or 8 subframe durations, it is determined that delayed cell is timing reference cell, advanced small Area is paired plot.The pre-defined strategy is primarily to subsequently pressing the processing time of UE sides and Node B sides During contracting, it is ensured that UE sides and Node B sides can have enough processing times to complete the work of itself.

In summary, the timing reference that the present embodiment two is provided determines that method can reasonably determine it from two cells In cell be timing reference cell, and determine that method is determined behind timing reference cell using this timing reference, Ke Yi When the follow-up processing time to UE sides and Node B sides is compressed, it is ensured that UE sides and Node B sides can have enough processing Time completes the work of itself.

, can also be by it should be noted that this timing reference determines that method can be completed by such as RNC management node UE itself is completed, and is generally completed by management node.In order to describe various aspects of the invention, below in conjunction with specific reality Environment is applied to be described in detail with different embodiments.

Embodiment three

Assuming that in the present embodiment, specific implement scene is：The dispatching cycle of the HARQ processes of two cells is 6 sons Time delay between frame duration, pairing subframe is 1.5 time slots.Determine that the process of timing reference cell is completed by management node.

Fig. 5 A are refer to, the method flow diagram of the timing method provided it illustrates the embodiment of the present invention three.The timing side Method can be used in the communication system shown in Fig. 2A or Fig. 2 B, and it is different that the communication system can include two down channel timings Cell, two cells carry out downlink transfer using high-speed downlink packet access.Certainly, those skilled in the art can be easy Full of beard and, the timing method can be used for the scene such as dual-carrier double cell and the cell of dual carrier four.The timing method can With including：

Step 501, management node obtains the turn-on time poor information of mobile terminal reporting；

Turn-on time difference information namely SFN-SFN observed time difference, the information is by P-CCPCH What the SFN information of (Primary Common Control Physical Channel, Primary Common Control Physical Channel) was obtained. UE can observe that this turn-on time is poor, and be reported RNC.The concrete numerical value of turn-on time difference generally uses chip The unit of level is characterized, and can characterize the timing offset of two cells.

Step 502, management node generates the subframe pair relationhip of two cells according to turn-on time difference；

Turn-on time that RNC can be reported according to UE poor information produces the subframe pair relationhip of two cells.Due to needing Downstream signal is sent using two cell coordinations, then the subframe that two cells are sent respectively to UE has mutual pair relationhip. Specifically, the content of subframe pair relationhip herein can be specifically any of following two forms：The first, two is small The System Frame Number and subframe numbers for two subframes matched each other in area；Second, the first subframe matched each other in two cells and In second subframe, the System Frame Number and subframe numbers of the first subframe, and the second subframe are biased relative to the System Frame Number of the first subframe With subframe numbers biasing.Here System Frame Number biasing and subframe numbers biasing is integer.Two subframes matched each other can be Two subframes matched each other in HS-SCCH channels or two subframes matched each other in HS-PDSCH channels.

Step 503, management node determines each other to match somebody with somebody in two cells according to turn-on time poor information and subframe pair relationhip To two subframes time context；

RNC according to turn-on time poor information and subframe pair relationhip it is determined that after subframe pair relationhip, can determine two The time context for two subframes matched each other in cell.Such as, the time context for two subframes matched each other It is one of subframe than another subframe fast 1.5 time slot in time.For the ease of description, incorporated by reference to Fig. 5 B are referred to, it shows The timing relation figure of each interchannel in the present embodiment.Assuming that HS-SCCH1 channels and HS-PDSCH1 channels belong to one Cell, and HS-SCCH2 channels and HS-PDSCH2 channels belong to another cell, HS-DPCCH channels are then the two cells In serving cell carrying uplink feedback channel.From the foregoing it will be appreciated that first subframe 512 in HS-SCCH1 channels is used to hold The control signal of first subframe 514 in decoding HS-PDSCH1 channels is carried, so wanting leading 2 time slots to send；Similarly, HS- First subframe 522 in SCCH2 channels is used to carry the control letter of first subframe 524 in decoding HS-PDSCH2 channels Number, so also wanting leading 2 time slots to send.RNC is it is determined that after subframe pair relationhip, determine first in HS-SCCH1 channels First subframe 522 in subframe 512 and HS-SCCH2 channels matches subframe each other, then can be with according to turn-on time poor information Know first subframe, 522 fast 1.5 time slots in first subframe 512 and the HS-SCCH2 channels in HS-SCCH1 channels. So RNC can determine first subframe 512 in HS-SCCH1 channels for advanced subframe, first in HS-SCCH2 channels Subframe 522 is delayed subframe.

Step 504, management node determines two according to the time context for two subframes matched each other in two cells Advanced cell and delayed cell in individual cell；

RNC determines that first subframe 512 in HS-SCCH1 channels is first in advanced subframe, HS-SCCH2 channels Subframe 522 is after delayed subframe, it is possible to which it is advanced cell to determine HS-SCCH1 channels affiliated subdistrict, and HS-SCCH2 channels Affiliated subdistrict is delayed cell.

Step 505, management node determines to surpass according to the dispatching cycle of the hybrid automatic repeat request process of advanced cell One in preceding cell and delayed cell is timing reference cell, and another is paired plot；

RNC can get the dispatching cycle of the HARQ processes of advanced cell and delayed cell.In the present embodiment, RNC The dispatching cycle that the HARQ processes of advanced cell can be got is 6 subframe durations, therefore what RNC can be provided according to embodiment two Timing reference determines that method determines that advanced cell is timing reference cell, and delayed cell is paired plot.

Step 506, management node generates timing reference information according to the identification information of timing reference cell；

The timing reference information generally includes the identification information as timing reference cell in both of the aforesaid cell, the mark It can be cell sequence number to know information, and cell sequence number is nonnegative integer.

Step 507, management node sends subframe pair relationhip and timing reference information to mobile terminal；

Subframe pair relationhip and timing reference information can all be sent to mobile whole by RNC in the identical or different time End, so that mobile terminal receives subframe.Preferably, RNC can also be sent to mobile terminal simultaneously sending timing reference information One feedback time configured information, the feedback time configured information is used to indicate a predetermined time slot length.The predetermined time slot length Span is [time slot of 7.5 time slot -1.5, the time slot of 7.5 time slot+1.5].

Step 508, mobile terminal knows that one in two cells is timing reference cell according to timing reference information；

UE can be after timing reference information be received, and it is timing reference cell to know HS-SCCH1 channels affiliated subdistrict, And HS-SCCH2 channels affiliated subdistrict is paired plot.

Step 509, mobile terminal receives the pairing subframe of two cells, and the subframe in timing reference cell is received Afterwards, again by feeding back hybrid automatic repeat-request confirmation, the hybrid automatic repeat-request confirmation letter during predetermined time slot length Cease simultaneously to carry out the pairing subframe in described two cells the hybrid automatic repeat-request confirmation of joint feedback.

The subframe pair relationhip for two cells that UE can be sent according to RNC receives the pairing subframe of two cells.Specifically Ground is said, it is necessary to by pre- timing after pairing subframes of the UE in the subframe in receiving timing reference cell and another cell HARQ-ACK information is fed back during gap length, HARQ-ACK information is while joins to two subframes matched each other in two cells Close the HARQ-ACK information of feedback.When the predetermined time slot length can be the feedback that default number or parsing RNC are sent Between configured information and the numerical value known.

Understand that UE can receive first subframe in the HS-SCCH1 channels in timing reference cell first with reference to Fig. 5 B 512, first subframe 514 in the HS-PDSCH1 channels in timing reference cell is then received after 2 time slots, this When UE can be in HS-SCCH1 channels first subframe 512 carrying control signal come in HS-PDSCH1 channels First subframe 514 such as is demodulated and decoded at the work.UE can also differ 1.5 time slot when receive paired plot in HS- First subframe 522 in SCCH2 channels, then receives the HS-PDSCH2 letters in timing reference cell after 2 time slots First subframe 524 in road, the control signal that now UE can be carried according to first in HS-SCCH2 channels subframe 522 The work such as first subframe 524 in HS-PDSCH2 channels is demodulated and decoded.After receiving and being disposed, UE Fed back at the time of when needing after first subframe 514 in receiving HS-PDSCH1 channels and passing through predetermined time slot length HARQ-ACK information.The HARQ-ACK information is by the subframe 514 and the pairing subframe 524 of paired plot in timing reference cell Reception condition combined coding after HARQ-ACK information, generally account for a slot length, i.e., 532 shown in figure.That is, In order to which two cells can have correctly received feedback information, UE after the subframe 514 and subframe 524 of pairing subframe each other is received, There is one section to be used for being demodulated and decoding time of the two subframes, then must will be characterized after 7.5 time slots of agreement this two Whether individual subframe receives the HARQ-ACK feedback of the information of successful combined coding to HS-DPCCH channels.In this process, UE To the processing time T1 of the subframe 514 of timing reference cell_ueFor predetermined time slot length, namely about 7.5 time slots, but UE to To the processing time T2 of the subframe 524 of cell_ueIt can be compressed to：Predetermined time slot length-| subframe 514 with pairing subframe 524 when Between it is poor |, namely 6 time slots.And for Node B sides, timing reference cell own base station is needed after HARQ-ACK information is received The UE HARQ-ACK information fed back is handled, processing time T1_{node B}To be：The HARQ processes of timing reference cell Dispatching cycle shared by slot length-T3-T1_ue=4.5 time slots, then timing reference cell start to start the hair of subframe next time Send；Base station described in paired plot after HARQ-ACK information is received, it is necessary to UE feed back HARQ-ACK information handle, Processing time T2_{node B}It will be extended to：Slot length-T3-T2 shared by the dispatching cycle of the HARQ processes of paired plot_ue=6 Time slot, then paired plot start to start the transmission of subframe next time.

Wherein, T3=| the time slot between the subframe of HS-PDSCH channels and the corresponding subframe in HS-SCCH channels is poor |+ During (slot length shared by the subframe of HS-PDSCH channels)+(slot length shared by HARQ-ACK information)=2+3 time slot+1 of time slot The time slot of gap=6.

It should be noted that the possible range of the time difference between the pairing subframe of two cells is [- 1.5 time slots, when 1.5 Gap], it is not limited to 1.5 time slots assumed in the present embodiment.It is also in this way, no longer repeating one by one in other embodiments.

In summary, the timing method that the embodiment of the present invention three is provided can be by different in two down channel timings It is timing reference cell that one of cell is determined in cell, and HARQ-ACK information is fed back on the basis of the timing reference cell Technological means, solve UE and believed serving cell and two parts of HARQ-ACK of assistant service cell using same HS-DPCCH Breath carries out the timing problems faced during joint feedback, is pressed with reference to the processing time to UE and the affiliated Node B in paired plot Contracting or extension technological means, make UE and Node B all have sufficient time to handle the work of itself (such as Node B are at least The time of 4.5 time slots is needed to handle the work of itself), having reached allows UE in different small of two down channels timing The normal effect using multiple stream transmission technology in area.
