Description

Transmission of packet data method and system thereof during high speed downlink packet inserts

Technical field

The present invention relates to high speed downlink packet access technology, transmission of packet data during particularly high speed downlink packet inserts.

Background technology

3-G (Generation Three mobile communication system) UMTS (Universal Mobile TelecommunicationSystem, universal mobile telecommunications system) system owing to its strong multimedia communication capacity, high-speed data transmission speed and efficiently many advantages such as 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 (NodeB), realized descending high speed data transfer.

Those of ordinary skill in the art know that air interface technologies is the considerable part of various mobile communication standards, specifically just show by function to divide on physical channel that forms and the transmission channel that shines upon mutually with it.The UMTS basic version has just been divided seven kinds of transmission channels and mapping or independently tens kinds of physical channels mutually with it.

HSDPA is descending to comprise two physical channels, one is high-speed physical downlink shared channel (HS-PDSCH) (HighSpeed 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 ControlChannel, 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 HighSpeed-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; Multiplexing and channel coding (FDD) ", the HS-SCCH loaded information comprises: the new data indication of the redundancy versions of the modulation scheme information of the channel code collection information of 7 bits, 1 bit, the transport block size information of 6 bits, the HARQ procedural information of 3 bits, 3 bits and planisphere version information, 1 bit and the high speed descending sharing channel Radio Network Temporary Identifier of 16 bits (HS-DSCH Radio Network Temporary Identity 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.

Meanwhile, at UE side and universal mobile telecommunications system grounding wireless access network (UMTSTerrestrial Radio Access Network, abbreviation " UTRAN ") media interviews of side control (MediumAccess Control, abbreviation " MAC ") layer has also increased high speed media access control (Medium AccessControl-high speed, abbreviation " MAC-hs ") Flow Control of HSDPA is supported in the sublayer, fast dispatch, priority management, HARQ and transport format resource indication (Transport Format and ResourceIndicator is called for short " TFRI ") are selected.MAC-hs is positioned under another sublayer MAC-d (d refers to special use) of MAC layer, on the physical layer.Fig. 1 and Fig. 2 show the structure of the MAC-hs of UTRAN side and UE side respectively.

As shown in Figure 1, from radio network controller (Radio Network Controller, be called for short " RNC ") in after the MAC-d of each UE flows to MAC-hs entity among the Node B, at first by priority query's allocation units according to MAC-d protocol Data Unit (the Protocol DataUnit on the MAC-d stream, abbreviation " PDU ") priority, with allocation of packets buffer memory in the different priority queries, wait for Node B scheduling, be able to go up transmission at high-speed downlink shared channel (High Speed DownlinkShared Channel is called for short " HS-DSCH ").Wherein, the packet in each priority query is the MAC-d PDU with equal priority of same UE, and its size has nothing in common with each other.

Node B dispatches the data transmission of each priority query of each UE at each TTI, be that Node B selects the MAC-d PDU of the some in a certain priority query of a certain UE in the HS-DSCH of current TTI channel according to certain dispatching algorithm, selected MAC-d PDU is with multiplexing formation MAC-hs PDU, transferring to the HARQ entity again transmits by a certain HARQ process of this UE, wherein, a UE can have 8 independently HARQ processes at most.Transmission format resource combination (TFRC) selected cell then is responsible for being chosen in HS-DSCH and is gone up employed transformat and the resources such as parallel code channel number and corresponding spreading code, transmission block size, modulation scheme of comprising of transmission.

Wherein, the form of MAC-hs PDU as shown in Figure 3, the head of MAC-hs PDU comprises fields such as version sign (VF), queue number (Queue ID), transmission sequence number (TSN), MAC-d PDU Length Indication (SID), MAC-d PDU number N and sign F.Wherein, the VF field length is 1 bit, is used to identify the version of MAC-hs PDU, and the version number of current agreement is 0; Queue id field length is 3 bits, is used to identify the MAC-hs PDU of same priority formation; The TSN field length is 6 bits, is used to identify the sequence number of MAC-hs PDU, thereby makes the receiving terminal can be according to the original MAC-hs PDU of SN recovery order; The SID field length is 3 bits, is used to indicate the length of same size sequence cascade MAC-d PDU together; The N field length is 7 bits, represents the number of same size sequence cascade MAC-d PDU together.The payload part of MAC-hs PDU is by a plurality of MAC-hs SDU, be MAC-d PDU, multiplexing forming, because that the identical but MAC-d PDU that vary in size of same priority formation medium priority has is multiple, therefore multiplexing MAC-d PDU on MAC-hs PDU has multiple different length.In the payload part of MAC-hs PDU, the MAC-d PDU concatenated in order of same length together, the number of its size and concatenated in order MAC-dPDU together is then by corresponding SID of MAC-hs PDU head and N field identification.Length is whether be MAC-d PDU pairing SID and the N field identification of another one size to the F field of 1 bit if then indicating follow-up, wherein, if the F field is " 0 ", represent that then follow-up is the pairing SID of MAC-dPDU and the N field identification of another one size, if field is the end that " 1 " then represents MAC-hs PDU head, promptly follow-up is the payload part of this MAC-hs PDU.

Node B according to the multiplexing formation of the form of MAC-hs PDU MAC-hs PDU, transfers to the HARQ entity with a plurality of MAC-d PDU in certain UE assigned priority formation at a TTI again, and a certain HARQ process by this UE is transferred to this UE.

In the UE side, as shown in Figure 2, the MAC-hs entity of UE side will at first be delivered to the HARQ entity from the MAC-hs PDU of HS-DSCH channel, the HARQ entity of UE side is the recipient of the HARQ entity of UTRAN side, is responsible for finishing generation and correctly replys operations such as (ACK)/wrong responses (NACK), the soft merging of HARQ.After the HARQ processing, the reorder queue unit is assigned to corresponding reorder queue according to the Queue id field of MAC-hs PDU head with this MAC-hs PDU, and in reorder queue, TSN field according to each MAC-hs PDU head is resequenced to each MAC-hs PDU, thereby recover original packet sequence, at last, the MAC-hs PDU that has recovered original order is admitted to the partition unit, and the partition unit splits out each MAC-d PDU and is sent to the MAC-d entity according to SID, the N of MAC-hs PDU head and the F field payload part branch from MAC-hs PDU.

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 is called for short " VoIP ") technology is exactly typical case wherein.

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

According to 3GPP technical report " TR25.862; RAB support for IMS ", on wireless air interface, with relevant grouping comprises four classes based on the VoIP Business Stream of IMS, be RTP (the Real Time Transfer Protocol of voice-bearer, be called for short " RTP ") grouping, be used for periodically real-time transmission of information control protocols such as mass parameter (the Real TimeTransfer Control Protocol of transfer medium transmission, be called for short " RTCP ") grouping, carrying conversation initialized protocol (SessionInitiation Protocol, be called for short " SIP ") signaling IP grouping, and carrier signaling radio bearer (SignalingRadio Bearer, abbreviation " SRB ") grouping, at down direction, VoIP transmission based on HSDPA needs the above-mentioned four kinds of groupings of transmission, these four kinds of groupings have different service attributes, the RTP grouping is the Business Stream relatively more responsive to time delay of constant rate of speed basically, depend on the speech coding algorithm that is adopted, its typical speed is 15-25kbps, SIP and RTCP attribute are approaching, have stronger suddenly, and SRB mainly carries the controlled in wireless signaling.No matter SIP, SRB or RTCP, its peak rate is typically below 15kbps.According to the characteristic of all kinds of groupings among the VoIP, typically, can be one of following mode based on the RAB (Radio Access Bearer is called for short " RAB ") of the VoIP of HSDPA:

(1) RTP and SIP/RTCP/SRB are carried on respectively on the RAB, send this 2 kinds of data flow at the MAC-hs layer with 2 priority queries accordingly.

(2) RTP, SIP/RTCP and SRB are carried on respectively on the RAB, send this 3 kinds of data flow at the MAC-hs layer with 3 priority queries accordingly.

(3) RTP, SIP, RTCP and SRB are carried on respectively on the RAB, send this 4 kinds of data flow at the MAC-hs layer with 4 priority queries accordingly.

Wherein, can be for mode (3) further with reference to 3GPP motion " R2-060569, VoIPReference Configurations, Nokia, 2006-02 " and " R2-060433, PS DefaultConfigurations, Nokia, 2006-02 ".

In actual applications, there is following problem in such scheme: during based on the small packet service of low rate among the HSDPA transmission VoIP etc., utilization ratio of wireless resources is lower.

Cause the main cause of this situation to be, because HSDPA can only transmit among the UE grouped data in the MAC-hs priority query in a TTI in the prior art, 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.

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.

Transmission of packet data method among the HSDPA of the present invention, its core are that at first, at least two UE are set to a UE group, and distribute a group id for it; Afterwards, network side grouped data that different UEs in the same UE group is to be sent is multiplexing to be sent in a MAC-hs PDU, and the group id of this UE group is set for this MAC-hs PDU; Subsequently, each UE collects corresponding M AC-hs PDU according to the group id of UE group under it, to therefrom obtaining the grouped data that belongs to this UE behind its demultiplexing.

Below transmission of packet data system and method among the first embodiment of the invention HSDPA is described.

Transmission of packet data system such as Fig. 4 and shown in Figure 5 among the HSDPA comprise the MAC-hs entity respectively in network side and UE.As shown in Figure 4, except that original priority query, priority query's distribution module, HARQ entity and TFRC select module, also comprise the multiplexing Multiplexing module of MAC-hs PDU that is used for different UEs different priorities formation in the same UE group in the MAC-hs entity of network side at a MAC-hs PDU; Equally, as shown in Figure 5, in the MAC-hs of UE side entity, except original partition module, the module that reorders, reorder queue distribution module, HARQ entity, also comprise the demultiplexing module that is used for the MAC-hs PDU that receives is carried out demultiplexing.

Specifically, at network side, after the MAC-d PDU of a plurality of UE enters the MAC-hs entity, at first by the priority of priority query's distribution module according to each MAC-d PDU, be assigned to buffer memory in the different priority queries, MAC-d PDU in the formation of same UE same priority is multiplexing in a MAC-hs PDU, afterwards, Multiplexing module is further multiplexing in a MAC-hs PDU with the MAC-hs PDU of the different priorities formation of different UEs in the same UE group, and the group id of this UE group is set for it, subsequently, transferring to the HARQ entity transmits by a certain HARQ process of this UE group.In the UE side, UE receives the MAC-hs PDU of this UE group according to the group id of UE group under it, carry out processing such as ACK/NACK replys by the HARQ entity in the MAC-hs entity, then the MAC-hs PDU that this UE that receives organizes is carried out demultiplexing by demultiplexing module, therefrom obtain the MAC-hs PDU that belongs to this UE, and further decomposite the MAC-hs PDU of different priorities, subsequently, the reorder queue module is assigned to corresponding reorder queue with the MAC-hs PDU of different priorities and resequences, thereby recover original packet sequence, at last, the MAC-hs PDU that has recovered original order is admitted to the partition module, splits out each MAC-d PDU and is sent to the MAC-d entity from the payload part branch of MAC-hs PDU.

More than system of the present invention is illustrated, below transmission of packet data method among the first embodiment of the invention HSDPA is described in detail.

As shown in Figure 6, in step 610, at least two UE are set to a UE group, are group id of this UE set of dispense.This group id can be H-RNTI, like this, and according to the present invention, for any one UE in the UE group, all can obtain two H-RNTI of system assignment, one is the H-RNTI that is used to identify UE self of the prior art, and another one is the H-RNTI that is used to identify its affiliated UE group.

In step 620, network side will need to send, and the MAC-hsPDU of different UEs is multiplexing in the same UE group sends in a MAC-hs PDU, and wherein, the MAC-hs PDU of each UE can be the MAC-hs PDU of different priorities formation.And the group id of this UE group is set for the MAC-hs PDU after multiplexing.Specifically, the MAC-hs PDU of different UEs was multiplexing in network side can be organized same UE sends in a MAC-hs PDU, perhaps, in order further to utilize Radio Resource, and then the MAC-hs PDU in the different priorities formation of different UEs in the same UE group is multiplexed into a MAC-hs PDU, and for this MAC-hs PDU is provided with the group id that this UE organizes, when organizing #1 as this UE group for UE, this MAC-hs PDU is set to the group id of UE group #1.

Such as, with the MAC-hsSDU that is buffered in each priority query of each UE in the UE group, be MAC-d PDU, be multiplexed with the MAC-hs PDU of respective priority formation respectively, afterwards, the MAC-hs PDU of interior different UEs different priorities formation is multiplexing in a MAC-hsPDU (as shown in Figure 7) on the same group again, and sends behind the group id that this UE group is set for this MAC-hs PDU.Multiplexing by the PDU that realizes many UE, many formations, solved effectively owing to the low transmission bandwidth problem that causes to make full use of HSDPA of the streaming rate of low rate small packet services such as VoIP in different MAC-hs priority queries, thereby the wireless network resource utilance when having improved low rate small packet service such as transmission VoIP among the HSDPA, and further enlarged the small packet service users' such as VoIP of each sub-district capacity.

Generally speaking, can pass through priority query's field, promptly Queue ID discerns the MAC-hs PDU of the different priorities formation of UE different in this UE group and this UE.Existing protocol Queue id field length is 3 bits, can distinguish 8 priority queries of same UE, yet for the VoIP business, even when adopting RTP, SIP, RTCP and SRB to be carried on a transmission means on the RAB respectively, also only need to use 4 priority queries, therefore, can be set to a UE group by two UE, making the Queue id field is 0～3 o'clock, indicate 4 priority queries of UE1 in this UE group, the Queue id field is 4～7 o'clock, indicates 4 priority queries of UE2 in this UE group; And when adopting RTP and SIP/RTCP/SRB to be carried on a transmission means on the RAB separately, each UE only need use 2 priority queries, in the case, then can be set to a UE group by four UE, make the MAC-hsPDU of the different priorities formation of the corresponding different UEs of different Queue id field values equally.By belonging to the grouped data of different UEs among number differentiation MAC-hs PDU of priority query, reused the UE identification method of existing protocol fully, protocol architecture, very little to the change of existing protocol, have good backwards compatibility with existing protocol.But medium priority number of queues of the present invention is not limited to 8, that is to say that Queue id field length is not limited to 3 bits.For example, allow to have at most 16 priority queries, then Queue id field length can be taken as 4 bits, if promptly the UE group comprises 4 UE at most, then can be per 4 corresponding UE of priority queries, promptly Queue ID is respectively 0～3,4～7,8～11,12～15 priority query corresponding UE #1, UE#2, UE#3, UE#4 respectively.And for example, allow to have at most 30 priority queries, then Queue id field length can be taken as 5 bits, if promptly the UE group comprises 6 UE at most, then can be per 5 corresponding UE of priority queries, promptly Queue ID is respectively 0～4,5～9,10～14,15～19,20～24,25～29 priority query corresponding UE #1, UE#2, UE#3, UE#4, UE#5, UE#6 respectively.

In step 630, UE collects corresponding M AC-hsPDU according to the group id of the group of the UE under it, obtains the MAC-d PDU of himself.Specifically, UE judges according to the group id H-RNTI of the group of the UE under it whether MAC-hs PDU belongs to this UE group, receive to obtain to belong to the MAC-hs PDU of this UE group, and number from this MAC-hs PDU, isolate the MAC-hs PDU of the respective priority formation that belongs to this UE according to different priority queries.At above-mentioned example, UE1 receives the MAC-hs PDU of UE group #1 under it according to group id H-RNTI, therefrom isolates the MAC-hs PDU that belongs to the formation of this UE respective priority, and promptly the Queue id field is 0～3 MAC-hs PDU.

Whether it should be noted that UE is by the monitoring to the HS-SCCH channel, judging has data to receive on the HS-PDSCH of corresponding TTI and obtains to receive the HS-PDSCH information needed according to HS-SCCH.Therefore, in step 630, UE is by the monitoring to the HS-SCCH channel, group id according to the group of the UE under it, judge that the data that whether have this UE to organize on the HS-PDSCH of corresponding TTI are that MAC-hs PDU needs to receive, and receive the HS-PDSCH of corresponding TTI according to the reception HS-PDSCH information needed that HS-SCCH obtained.

Yet, UE can monitor 4 HS-SCCH channels usually simultaneously, but,, then only monitor this HS-SCCH channel at back to back n this UE of subframe when UE receives on certain HS-SCCH when on the corresponding HS-PDSCH of indication one's own data being arranged n-1 subframe.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, make UE monitor different separately HS-SCCH channels, at this moment each UE just can not receive the MAC-hs PDU that UE organizes simultaneously in the UE group.Different UEs can receive multiplexing MAC-hs PDU in this UE group in order to make, and therefore, in step 620 and step 630, can adopt one of following (but being not limited to) 2 kinds of schemes to realize that each UE can receive the MAC-hs PDU that UE organizes simultaneously in the UE group:

1, network side is when sending the MAC-hs PDU of multiplexing UE group, in order to make UE can correctly receive this MAC-hs PDU, can be 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 (this control information comprises the group id that UE organizes) 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 MAC-hs PDU 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, wherein said other HS-SCCH channel is indicated the control information (this control information comprises the group id of UE group) of this UE group transmission.

In step 640, network side judges whether to receive the affirmation response message of all UE in the same UE group, if do not receive then enter step 650.Specifically, if each UE has correctly received the MAC-hs PDU of its UE group in the same UE group, then return ACK and corresponding C QI, otherwise, then return NACK and corresponding C QI, network side judge receive response message whether be ACK, if receive the NACK of one or more UE, then enter step 650.

In step 650, network side receives NACK and the corresponding C QI thereof from least one UE in the same UE group, so network side retransmits the MAC-hs PDU of this UE group, the ACK of all UE in receiving this UE group, and according to indicating the CQI value of minimum speed limit to dispatch and distributing radio resource among its corresponding C QI.Thereby guarantee that all UE in this UE group all can effectively receive the MAC-hs PDU of its affiliated UE group.For the UE of the MAC-hs PDU that correctly receives its UE group,, then ignore processing to the MAC-hs PDU of the UE group of this re-transmission if received the MAC-hs PDU of the UE group that retransmits.

The transmission of packet data system and method and first execution mode are roughly the same among the second embodiment of the invention HSDPA, its difference only is that the MAC-hs PDU of the different priorities formation of different UEs in same UE group of network side in first execution mode is multiplexing in a MAC-hs PDU time, number discerns same UE different UE and different priorities formation of UE in organizing with different priority queries; And the MAC-hs PDU of network side different priorities formation of different UEs in same UE group is multiplexing in a MAC-hs PDU time in the present embodiment, by newly-increased UE identification field in this MAC-hs PDU, to discern different UE in the same UE group, simultaneously, newly-increased be used for indicating UE this MAC-hs PDU the amount field of multiplexing MAC-hs PDU number, and the filling field, as shown in Figure 8.

Specifically, the MAC-hs PDU of network side each UE in same UE group is multiplexing in a MAC-hs PDU time, at first the MAC-hs PDU of the different priorities formation of same UE is multiplexed into the MAC-hs PDU of this UE, wherein, still continue to use prior art, Queue ID only is used to distinguish the different priorities formation of same UE.Then, the MAC-hs PDU of different UEs is multiplexed into a MAC-hs PDU again.In order to identify the MAC-hs PDU of different UEs among this MAC-hs PDU, before the MAC-hs of each UE PDU, add a UE identification field, be used to indicate the different UEs in the UE group, H-RNTI that this UE identification field can be UE or self-defining temporary mark.The MAC-hs PDU number of the different priorities formation that comprises for further this UE of indication is added an amount field again.Like this, after UE is to the MAC-hs PDU demultiplexing that receives, can obtain the MAC-hs PDU that belongs to this UE according to this UE identification field and amount field.

With the MAC-hs PDU of different UEs multiplexing together after, add to fill field again.For the MAC-hs PDU and filling field that distinguishes each UE, the afterbody of MAC-hs PDU after this is multiplexing has increased by one and has optionally filled pointer field, be used to indicate the original position of filling field, and a filling pointer mark PF, be used to indicate whether exist the filling pointer field.When filling field length more than or equal to the bit number summation of UE identification field and amount field, there is the filling pointer field in the FP indication; When filling field length less than the bit number summation of UE identification field and amount field, FP indicates and does not have the filling pointer field.Fill pointer mark PF and can be a bit preceding, the most last or appointment among this MAC-hs PDU after multiplexing.

At receiving terminal, each UE receives corresponding M AC-hsPDU according to the group id of the group of the UE under it, and it is carried out demultiplexing, UE reads the filling pointer mark FP among this MAC-hs PDU, if existing, the FP indication fills pointer field, then read the filling pointer field, and decompose this MAC-hsPDU, till arriving the original position of filling the indicated filling field of pointer field.If there is not the filling pointer field in FP indication, then directly decompose this MAC-hs PDU, and the length of statistics residue field, when the length of residue field during, stop decomposition less than the bit number summation of UE identification field and amount field.Each UE is by to the demultiplexing of the MAC-hs PDU that receives and the data that the UE identification field in this MAC-hs PDU obtains self.

The transmission of packet data system and method and first execution mode are roughly the same among the third embodiment of the invention HSDPA, and its difference only is the MAC-hs PDU form difference after multiplexing.The MAC-hs PDU of network side different priorities formation of different UEs in same UE group is multiplexing in a MAC-hs PDU time in first execution mode, has adopted multiplexing MAC-hs PDU form shown in Figure 7; And the MAC-hs PDU of network side different priorities formation of different UEs in same UE group is multiplexing in a MAC-hs PDU time in the present embodiment, adopt multiplexing MAC-hsPDU form shown in Figure 9, specifically, among the MAC-hs PDU after multiplexing, a follow-up sign CF field is set between per two PDU, wherein, described CF field is used to indicate whether to also have follow-up data PDU, for example can stipulate that CF=0 represents follow-up data PDU in addition, and CF=1 represents not have follow-up data PDU, and is promptly follow-up for filling field.Wherein, when having the filling field, the CF field is set also behind the PDU of last UE, this CF indication does not have follow-up data MAC-hs PDU.When not having the filling field, there is not the CF field behind last PDU.

Specifically, the MAC-hs PDU of network side each UE in same UE group is multiplexing in a MAC-hs PDU process, at first the MAC-hs PDU with the different priorities formation of each UE is multiplexed into a multiplexing MAC-hs PDU, wherein, between the MAC-hs PDU of per two UE the CF field is set, and according to whether there being follow-up MAC-hs PDU that the value of CF is set, for example, when follow-up MAC-hs PDU was arranged, CF was set to 0.When having the filling field, the CF field also is set behind the PDU of last UE, this CF indication does not have follow-up data MAC-hs PDU.When not having the filling field, there is not the CF field behind last PDU.The form of this cascade PDU sends to UE with the PDU after multiplexing as shown in Figure 8.

At receiving terminal, each UE receives corresponding M AC-hs PDU according to the group id of the group of the UE under it, and it is carried out demultiplexing, UE handles successively to each MAC-hs PDU, and wherein, the priority query by each PDU number discerns one's own MAC-hs PDU, whenever after handling a PDU, judge whether follow-up data in addition,, then continue to handle next PDU if having; If there is no data, or CF indication follow-up data promptly shows the processing of having finished this multiplexing MAC-hs PDU for filling field (for example CF=1).

The transmission of packet data system and method and second execution mode are roughly the same among the four embodiment of the invention HSDPA, and its difference only is the MAC-hs PDU form difference after multiplexing.The MAC-hs PDU of network side different priorities formation of different UEs in same UE group is multiplexing in a MAC-hs PDU time in second execution mode, has adopted multiplexing MAC-hs PDU form shown in Figure 8; And the MAC-hs PDU of network side different priorities formation of different UEs in same UE group is multiplexing in a MAC-hs PDU time in the present embodiment, adopts multiplexing MAC-hs PDU form shown in Figure 10.Specifically, among the MAC-hs PDU after multiplexing, MAC-hs PDU after the MAC-hs PDU of the different priorities formation of each same UE is multiplexing (comprises the UE identification field, the MAC-hs PDU of amount field and variant priority query) between, a follow-up sign CF field is set, wherein, described CF field is used to indicate whether to exist the follow-up data MAC-hs PDU after another one UE multiplexing, for example, can stipulate that CF=0 represents the follow-up MAC-hs PDU that also has after another one UE multiplexing, and CF=1 represents the follow-up MAC-hs PDU that has not had after another one UE multiplexing, and is promptly follow-up for filling field.Wherein, when exist filling field, the back of the MAC-hs PDU after last UE multiplexing also is provided with the CF field, and this CF indication follow-up data is not for existing the follow-up data MAC-hs PDU after another one UE multiplexing.When not existing when filling field, there is not the CF field behind the MAC-hs PDU after last UE multiplexing.

Specifically, the MAC-hs PDU of network side each UE in same UE group is multiplexing in a MAC-hs PDU time, at first form the MAC-hs PDU of different priorities formation of the same UE MAC-hs PDU after multiplexing, wherein, identical with second execution mode, MAC-hs PDU after multiplexing comprises fields such as UE identification field and amount field, between the MAC-hs PDU after per two UE multiplexing the CF field is set, and the CF field is set to indicate the value of the MAC-hs PDU after the follow-up another one UE of also having multiplexing, for example CF=0.When exist filling field, behind the MAC-hs PDU after last UE multiplexing the CF field is set also, this CF indication does not have follow-up data.When not existing when filling field, there is not the CF field behind the MAC-hs PDU after last UE multiplexing.The form of this cascade PDU sends to UE with the PDU after multiplexing as shown in figure 10.

At receiving terminal, each UE receives corresponding M AC-hs PDU according to the group id of the group of the UE under it, and it is carried out demultiplexing, and decomposite MAC-hs PDU after each UE multiplexing successively according to the CF field, obtain the MAC-hs PDU that belongs to this UE according to UE identification field and amount field.Wherein, whether to one's name UE judges the MAC-hs PDU of each UE after multiplexing according to the UE identification field, if then further adopting the second execution mode identical operations handles oneself MAC-hs PDU, if not then judge the follow-up MAC-hs PDU that whether also has after next UE multiplexing according to the CF field, if the follow-up PDU (for example CF=0) in addition of UE CF indication, then continue to handle the MAC-hs PDU after next same UE multiplexing, if there is no data, or CF indication follow-up data promptly shows the processing of having finished this multiplexing MAC-hs PDU for filling field (for example CF=1).

Although it should be noted that the MAC-hs PDU form that also exists after other multiplexing,, the principle of multi-user's transmission plan of above-mentioned execution mode and thought also are same being suitable for.

Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
