Description

Data multiplexing method of multi-user device and system thereof in the mobile communications network

Technical field

The present invention relates to mobile communication technology, particularly the data multiplex of multi-user installation in the mobile communications network.

Background technology

Third generation universal mobile telecommunications system (Universal Mobile Telecommunications System, be called for short " UMTS ") owing to its strong multimedia communication capacity, high-speed data transmission speed and efficiently many advantages such as the availability of frequency spectrum gain great popularity, and become the developing goal of future mobile communications.One of key property of UMTS technology R5 version is exactly that high speed downlink packet inserts (High Speed Downlink Packet Access, be called for short " HSDPA "), promptly by adaptive modulation and coding (Adaptive Modulation and Coding, abbreviation " AMC "), mix re-transmission (Hybrid Automatic Repeat reQuest, be called for short " HARQ "), and the series of key techniques such as fast dispatch of base-station node (Node B), realized descending high speed data transfer.

HSDPA is descending to comprise two physical channels, one is high-speed physical downlink shared channel (HS-PDSCH) (High Speed Physical Downlink Shared Channel, be called for short " HS-PDSCH "), be used to carry user's data information, another is High-Speed Shared Control Channel (High Speed Shared Control Channel, be called for short " HS-SCCH "), be used to carry the required signaling of demodulation companion data channel HS-PDSCH.In addition, HSDPA is at a up High-Speed Dedicated Physical Control Channel (the High Speed-Dedicated Physical Control Channel that increased, be called for short " HS-DPCCH "), this channel is used to carry the feeding back downlink Frame receives correctness by HS-PDSCH information, perhaps be used for feedback channel quality indication (Channel Quality Indicator is called for short " CQI ").

Subscriber equipment (User Equipment, be called for short " UE ") know whether have Node B to send to its data on the corresponding HS-PDSCH by HS-SCCH, also from HS-SCCH obtain demodulation HS-PDSCH required comprise transformat and resource informations such as parallel code channel number and corresponding spreading code, transmission block size, modulation scheme, Node B then knows by HS-DPCCH whether data are correctly received, if it is incorrect, to initiate to retransmit, otherwise send new data.

Specifically, at each Transmission Time Interval (Transmission Time Interval, be called for short " TTI ") on, HS-PDSCH can only transmit the data of a UE, UE by monitor HS-SCCH judge corresponding TTI the HS-PDSCH channel bearing whether be one's own data.According to 3GPP standard " TS 25.212 " multiplexed and chnnel coding (Multiplexing and channel coding) " ", the HS-SCCH loaded information comprises: the channel code collection information of 7 bits, the modulation scheme information of 1 bit, the transport block size information of 6 bits, the HARQ procedural information of 3 bits, the redundancy versions of 3 bits and planisphere version information, the new data indication of 1 bit and the high speed descending sharing channel Radio Network Temporary Identifier of 16 bits (HS-DSCH Radio Network Temporary Identifier is called for short " H-RNTI ").UE be exactly according to the UE of 16 bits that carry on HS-SCCH sign H-RNTI judge corresponding TTI the HS-PDSCH channel bearing whether be one's own data.

Because remarkable advantages such as downlink transfer speed is big, propagation delay time is little, HSDPA is by increasing professional the use, based on internet protocol multimedia core network subsystem (IP Multimedia Subsystem, abbreviation " IMS ") packet voice (Voice over IP, abbreviation " VoIP ") technology is exactly typical case wherein, another example recreation (Game over IP, be called for short " GoIP ") business of dividing into groups exactly.

For carrying VoIP service efficiently, generally adopt the HSDPA/ high speed downlink packet to insert (High Speed Uplink Packet Access, be called for short " HSUPA ") bearing mode, wherein HSDPA is used for the VoIP data of bearing downlink direction, and HSUPA is used to carry the VoIP data of up direction.

Because HSDPA can only transmit among the UE grouped data in the MAC-hs priority query in a TTI, and it is lower based on the professional total peak rate of the VoIP of HSDPA, if packet data streams different among the VoIP is further segmented the back to be transmitted in different MAC-hs priority queries, to cause each priority query to have lower speed, be far smaller than the transmission bandwidth of HSDPA, cause a large amount of residue transmission bandwidths not to be utilized, and also have data to be transmitted such as a large amount of in other MAC-hs priority queries among many other UE that use the VoIP business among this UE or in this sub-district.

In order to solve the lower problem of transmission bandwidth utilance, proposition is with media interviews control (the Medium Access Control of a plurality of UE, abbreviation " MAC ") layer data is grouped in the method for transmitting behind MAC layer and the physical layer multiplex in a TTI, as shown in Figure 1, thereby effectively improved utilization ratio of wireless resources, and helped improving each small packet service user's such as sub-district VoIP, GoIP capacity.

In order to transmit the multiplexing transmission block of many UE to two or more UE simultaneously, divide into groups pairing UE of each multiplexing MAC layer data is together formed a UE group, be H-RNTI of UE group allocation, be used to identify this UE group, make the UE in this UE group can be according to the correct packet that receives after multiplexing of H-RNTI.

In actual applications, there is following problem in such scheme: increased extra power consumption and the unnecessary consumption of Radio Resource of UE.

Cause the main cause of this situation to be, because UE number and each UE in the UE group are pre-configured, all UE in the same UE group always receive the HS-PDSCH channel according to the indication of the H-RNTI of this UE group simultaneously, therefore, even may not have the data that oneself need reception on this HS-PDSCH channel, also still receive and decoding HS-PDSCH channel, by the corresponding UE sign of identification, judge the data whether oneself is arranged on this HS-PDSCH channel again.This will increase the unnecessary reception operation of UE, thereby increase the UE power consumption.And, receiving and handling in the process that does not need the data that receive at UE, running into cyclic redundancy check (CRC) (Cyclic Redundancy Check, be called for short " CRC ") during the situation of failure, this UE still will send NACK (not confirming), notice Node B retransmits, thereby causes the unnecessary consumption of Radio Resource.

Summary of the invention

In view of this, main purpose of the present invention is to provide data multiplexing method of multi-user device and system thereof in a kind of mobile communications network, when making the data multiplex of a plurality of UE in the TTI of HS-PDSCH, can reduce the processing burden of UE and to the re-transmission demand of Node B.

Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.

Embodiments of the invention are to carry out the transmission of many UE data multiplex by HSDPA, and at first at least two UE are set to a UE group, are its assign group sign; Subsequently, network side sends the multiplexing back of grouped data that needs send to each UE in this UE group at first channel, and on corresponding second channel, a temporary mark is set, the first of this temporary mark is the group id of this UE group, second portion indicates whether each UE has transfer of data in this UE group, as shown in Figure 2; Afterwards, UE collects temporary mark from second channel, whether the first of judging this temporary mark is the group id of this UE group, and further judge whether to exist the data of this UE according to the second portion of this temporary mark, if the first of this temporary mark indicates the data that this UE is arranged for the group id and the second portion of this group, then corresponding first channel is handled and demultiplexing obtains the data of this UE, otherwise ignored processing corresponding first channel.

Below many UE data multiplex transmission method in the first embodiment of the invention mobile communications network is described in detail.

As shown in Figure 3, in step 310, at least two UE are set to a UE group, and are its assign group sign.Such as UE#0, UE#1 and UE#2 are set to a UE group, and are its assign group sign #10.

In step 320, network side sends the multiplexing back of grouped data that needs send to each UE in the group in the TTI of HS-PDSCH, and on corresponding HS-SCCH, a temporary mark is set, this temporary mark can be H-RNTI, the first of temporary mark is a group id, second portion indicates whether each UE has transfer of data in this group, usually, can make each UE indicates corresponding UE whether transfer of data is arranged corresponding to the different bits in the temporary mark second portion with those bits in the UE group.At above-mentioned example, network side at needs when UE#0 and UE#1 send grouped data, the multiplexing back of grouped data that needs is sent to UE#0 and UE#1 sends by HS-PDSCH, and first with H-RNTI, 13 bits as a H-RNTI high position, be set to its UE group id #10, and the 0th bit and the 1st bit in the second portion of H-RNTI all are set to 1, indicate UE#0 and UE#1 that transfer of data is arranged respectively, the 2nd bit is set to 0, indication UE#2 does not have transfer of data, afterwards, sends the H-RNTI that sets by HS-SCCH.

Shown in the left-half among Fig. 4, for the transmission of UE group, in the process of network side organizational controls information, after the required information via chnnel coding of demodulation HS-PDSCH, sequence scrambling with H-RNTI formation, form the first of HS-SCCH, as shown in Figure 5, described H-RNTI is except the group id part, and described H-RNTI also comprises the UE indicating section of representing with the fixed bit value, for example, suppose that the UE indicating section takies last 6 bits of H-RNTI, then described H-RNTI is " xxxxxxxx xx000000 " (wherein " x " expression group id part), perhaps uses " xxxx xxxx xx111111 " to represent described H-RNTI, or the like.Like this, when the UE in the UE group receives this HS-SCCH, just can decode to the first of HS-SCCH according to this H-RNTI.

Shown in the right half part among Fig. 4, the required information of demodulation HS-PDSCH also generates the CRC (cyclic check code) of 16 bits together with the required information of decoding HS-PDSCH, this CRC carries out the second portion that chnnel coding forms HS-SCCH with the required information of decoding HS-PDSCH after adding with the H-RNTI mould 2 of current UE group again.Because in the transmission of a UE group, UE in actual this UE group that transfer of data arranged is uncertain (UE indicating section difference), therefore (the group id part is identical to need to use different H-RNTI, but UE indicating section difference) CRC check is carried out in decoding output respectively, when can the control information of the HS-SCCH channel on this TTI be correctly decoded (CRC check by) when certain UE uses the H-RNTI of this UE group, then show in the UE group transmission on the indicated HS-PDSCH of the HS-SCCH channel of this TTI to have comprised the data that belong to this UE.

Like this, in step 330, UE receives H-RNTI from network side by HS-SCCH, and judges the group id whether first of H-RNTI organizes for this UE, if, then enter step 340, otherwise, step 370 then entered.

In step 340, UE judges whether to exist the data of this UE according to the second portion of H-RNTI.Specifically, UE according in the H-RNTI second portion with the corresponding bit of this UE, whether corresponding HS-PDSCH on have oneself data, if having then enter step 350, then do not enter step 370 if judging.Such as, UE#1 has judged the group id #10 of the first of H-RNTI for group under it, and then judge whether first bit is 1 in the H-RNTI second portion, if then represent to have on its corresponding HS-PDSCH the data of UE#1 to enter step 350, otherwise, if be 0, then expression does not have the data of UE#1, enters step 370 equally.

In

step

330 and 340, UE can monitor 4 HS-SCCH channels usually simultaneously, but, when UE receives on certain HS-SCCH when on the corresponding HS-PDSCH of indication one's own data being arranged n-1 subframe, then in back to back n subframe, according to prior art, this UE only monitors this HS-SCCH channel.Therefore, when two in the UE group and plural UE have one's own data on n-1 subframe listens to the HS-PDSCH of indication correspondence on certain HS-SCCH simultaneously, be when different UEs sent control information during the different HS-SCCH of Node B employing organized UE, different UEs can receive multiplexing grouped data in this UE group in order to make, and can adopt one of following (but being not limited to) 2 kinds of schemes:

1, when n subframe Node B carries out the transmission of UE group, the HS-SCCH channel that has comprised pairing n-1 the subframe monitoring of UE of data in this UE group transmission sends control information simultaneously, thereby make a plurality of UE in the UE group just can listen to the control information of this UE at former HS-SCCH channel, so that on n subframe, receive multiplexing grouped data according to control information n-1 subframe;

2, when the UE in the UE group has one's own data on n-1 subframe receives the HS-PDSCH of indication correspondence on certain HS-SCCH, can make UE in this UE group in back to back n subframe in this HS-SCCH channel of monitoring, also monitor at least one other HS-SCCH channel, the control information of this UE group transmission of at least one transmission indication in wherein said other HS-SCCH channel.

In

step

330 and 340, UE adopts following method to judge whether the grouped data of oneself according to H-RNTI, as shown in Figure 6, in the decode procedure of the HS-SCCH channel that transmits at the UE group, in step 61-62, after going to disturb, the sequence that UE forms with group id the first of HS-SCCH carries out channel-decoding, simultaneously, in step 63-65, second portion to HS-SCCH carries out channel-decoding and isolated information bit and CRC bit, a H-RNTI and the described CRC bit mould 2 got then in the H-RNTI combination of this UE group that comprises this UE indication add, then, in step 66, to step 62 decoded result, step 65 execution result and step 64 execution result execution in step 67: carry out CRC check, if CRC check is decoded successfully execution in step 69 by then showing HS-SCCH, the data that comprise this UE that the transmission of UE group is arranged on the corresponding HS-PDSCH, so UE will be further carries out the demodulation sign indicating number with the HS-SCCH control information that obtains of successfully decoding to corresponding HS-PDSCH; If CRC check is not passed through, execution in step 68, again get and carry out CRC check after next H-RNTI in the H-RNTI combination of this UE group that comprises this UE indication and described CRC bit mould 2 add, up to having attempted the H-RNTI that all comprise this possible UE group of this UE indication, CRC check is not passed through yet, then execution in step 70, show the data that comprise this UE that do not have the transmission of UE group on the corresponding HS-PDSCH, and ignore the decoding output bit of the HS-SCCH of this TTI.

Wherein, the described H-RNTI that comprises this possible UE group of this UE indication, the bit corresponding with this UE of its UE indicating section indicates corresponding HS-PDSCH to go up this UE transfer of data, and the other parts of UE indicating section are other any value.For example, the length of UE indicating section is 6 bits, stipulate that promptly the MAC layer data divides into groups to allow at most in many UE multiplexing transmission the MAC layer data Packet Multiplexing of 6 UE on a transmission block, the UE that is numbered #0～#5 is the bit that begins from lowest order of corresponding UE indicating section respectively, the UE that the HS-PDSCH of the corresponding TTI of definition bit " 1 " expression goes up this bit correspondence has transfer of data, the HS-PDSCH of the corresponding TTI of bit " 0 " expression goes up the UE free of data transmission of this bit correspondence, if the MTG group id partly is " 1001001101 ", then for the UE that is numbered #3, the H-RNTI that comprises this possible MTG of this UE indication is " 1001001101xx1xxxx ", wherein, " x " expression or be " 0 " or be " 1 ".

In step 350, UE judges whether the data on the HS-PDSCH are data retransmission, and whether has correctly received these data before this.Specifically, because under the situation of network side correct reception data answering message of all UE in not receiving same UE group, the content that is sent before can constantly retransmitting.The UE that correctly receives data in the same UE group remakes unnecessary reception, UE judges according to the new data indication information on the HS-SCCH channel whether the data on the corresponding HS-PDSCH are data retransmission, if data retransmission then further judges whether correctly received these data before this.If the data on the corresponding HS-PDSCH are data retransmissions, and correctly receive these data before this, then entered step 360, otherwise, step 370 then also entered.

In step 360, UE receives the decode corresponding HS-PDSCH, according to situation about receiving the decode, returns the response message that whether correctly receives data, if correctly received the data on the HS-PDSCH, then further obtain the data of this UE by demultiplexing.

In step 370, because the first of H-RNTI is not the group id of this UE group, the data that perhaps do not have this UE in the data of this UE group, or these data are data retransmission and have correctly received these data, UE ignores the processing to corresponding HS-PDSCH, thereby has alleviated the burden of UE processing signals.And reduce because UE receives the decode the chance of HS-PDSCH, the feasible also corresponding minimizing of chance because of receiving the decode the re-transmission that causes has reduced the possibility that retransmits, and has alleviated the burden of network side, has reduced taking interface-free resources.

More than many UE data multiplex transmission method in the first embodiment of the invention mobile communications network is elaborated, below many UE data multiplex transmission system in the second embodiment of the invention mobile communications network is described.
