Several examples are set forth below the solution of the present invention is described in detail.

The scheme that embodiment 1, the data to Different Logic channel are multiplexed.

In force, data block needs to be sent to physical layer, is sent out by physical layer, and can be same in physical layer resources When transmit all data.In order to improve efficiency of transmission, the embodiment of the present invention is by different type and comes from Different Logic channel Data are multiplexed, and carry out simultaneous transmission.

In order to improve the efficiency to data-reusing, header overhead is reduced as far as possible and keeps flexibility, the embodiment of the present invention Different Logic channel multiplexing can be taken part or all of in following manner：

First, send equipment the data for coming from Different Logic channel are placed in PDU, and with Logic Channel Identifier (such as Logical channel number) distinguish, after the packet of a logic channel is placed, then place the data of next logic channel；

2nd, if the control information of layer two based on terminal, sending equipment can be referred to special Logic Channel Identifier Show.

Optionally, in general the priority of control information is higher, therefore when control information and packet are answered Used time, control information can be placed on to the foremost of packet.

Wherein, the control information of layer two based on terminal includes but is not limited to part or all of in following message：

The descending activation/deactivation signaling of caching and power headroom reporting, UE of end side, DRX (Discontinuous Reception, discontinuous reception) signaling and other signalings etc..

3rd, Length Indication has been required to for each data block in each logic channel, in order to which receiving device decodes The data block gone out in logic channel, package and submit the operation of high level.

A kind of possible PDU structure is set forth below, as shown in Figure 3.It should be noted that the structure shown in Fig. 3 is A kind of possible implementation, as long as the PDU structures that can be multiplexed are all suitable for the embodiment of the present invention.

In Fig. 3, subheader 1, subheader 2 and subheader 3 constitute PDU head, control information below, data block 1, data block 2 and fill part be Payload.

The order of subheader is consistent with the order of data, i.e., subheader 1 is that head corresponding to control information indicates, subheader 2 It is that head corresponding to data block 1 and data block 2 indicates, subheader 3 is head instruction corresponding to filling padding parts.

LCID：Logical channel number (i.e. the Logic Channel Identifier of logic channel corresponding to data block), some of which is special Logical channel number, for indicating some special information, for example, 00000 instruction CCCH (Common Control Channel, CCCH), 10000-11111 regions indicate special control information, such as the caching and power headroom reporting of UE sides, Line activating deactivates signaling, DRX signalings and other signalings etc. under UE, and 00001-01111 regions are used to indicate the special of up-downgoing Logic channel.Transmitting terminal is connecing according to the attribute for sending data to logical channel number, receiving terminal corresponding to the setting of each data block After receiving the PDU, from different logical channel numbers it is known that corresponding data block is control information on earth, or special patrol The data of volume channel, different logic channels is sent to the data of different dedicated logical channels and handled, control information Corresponding module is sent to be handled.A special LCID may be also needed to, to indicate to fill.

E：Extension field (be used for the position corresponding to indicating after subheader whether be data area information), for indicating What the subheader continued below is next subheader or data division.By taking previous example as an example, the E domains in subheader 1 are arranged to 1, It may indicate that, subsequently followed by subheader 2 rather than data division, similarly the E domains of subheader 2 are also configured as 1, show and then prefix 3, And the E domains of subheader 3 need to be arranged to 0, it is last subheader to show this, subsequently then be data division.Accordingly, also may be used 0 representative is taken to follow subheader with E domains, and E domains take 1 to represent data, standard is provided or configured in advance.

E1：Extension field 1 (is used in subheader corresponding to indicating the information for whether having Length Indication), for indicating the subheader It is internal whether and then to have Length Indication.Such as inside subheader 1, because this is a control information, the length of the control information is Fixed, for example be fixed form, that avoids the need for Length Indication, and E1 domains could be arranged to 0；And for prefix 2 inside, One E1 domain is arranged to 1, and representing first data block needs LI to indicate, second E1 domain is arranged to 1, represents second data block LI is needed to indicate, the 3rd E1 is arranged to 0, and representative does not subsequently have LI.

LI：Length Indication domain (information for being used for the length of data block corresponding to indicating), to carry each data block Size, in units of byte.

In the above example, last subheader is the content of corresponding filling (padding).If scheduling can be according to treating The data of transmission are accurately controlled, then need not be filled；If the data block size and due-out of physical layer transmission It can not be matched well between, then, it is necessary to meet the size of physical layer transmission resource with byte of padding outside data block. For receiving device, byte of padding can be directly abandoned, it is not necessary to handled.

If the data that sending equipment needs to send are from two or more logic channel, equivalent to upper The data instruction that subheader 2 represents a logic channel is stated, a similar subheader, such as 2i can also be subsequently followed, to refer to Show the data of another logic channel, different Logic Channel Identifiers characterizes different logic channels, data block portions according to The data for needing to transmit carry out tissue, and multiple data blocks can have multiple Length Indications.

Optionally, control information is located at PDU initial part, and centre is the data of multiple logic channels, if last go back There is remainder to follow byte of padding.

In force, there can be two kinds of different indicating modes on Length Indication：

First, the byte length that equipment corresponds to each data block with each Length Indication is sent, logic channel is most The latter data block sends equipment and also carries out Length Indication, and marks the end position of the data of this logic channel；

2nd, send equipment to indicate using the length of logic channel integrated data block as entire length, internally refer to respectively again Show the length of each data block.

Length Indication because of entirety and the Length Indication of N-1 data block above, remaining length is necessarily The length of last data block, so last data block can not have to corresponding Length Indication,

In force, the size on Length Indication LI has following manner：

First, signaling static configuration LI size is passed through.

Such as 7 bits are configured to, or it is configured to 15 bits；7 bits, logic letter can also be configured to logic channel 1 Road 2 is configured to 15 bits.

2nd, by some form instructions field in the packet of transmission, dynamic instruction LI size is carried out.

Such as in above-mentioned subheader 2, increasing F2 domains, different with F2 domains are indicated to represent different LI size.

Such as 0 represent 7 bits, 1 represents 15 bits, and the benefit of dynamic instruction is can be according to the flexible in size of packet LI length is determined, more saves header overhead.

The scheme of embodiment 2, the first one logic channel internal data bag of transmission.

Inside a logic channel, it is possible to have the control information of logic channel aspect, just pass data and retransmit data. Here the control information of logic channel aspect is different from the control information in above-described embodiment 1, the control information in embodiment 1 It is the control information of UE ranks, and control information signified in embodiment 2 is the control information of logic channel level, such as AM moulds Some state reports feedback, head compression control information etc. of formula.

Equipment is sent when organizing the data block inside a logic channel, control information typically has highest priority, Retransmit data to take second place, it is minimum just to pass the priority of data, therefore when organizing bag also in this order, i.e., status information is positioned at most Above, it is finally just to pass data followed by data are retransmitted.

One kind group packet mode, it is to send equipment to arrange the data block of needs group bag according to priority orders, in PDU head The Length Indication of each data block is carried in portion, different data blocks is distinguished and then different processing is carried out to data block. Wherein this processing is probably to be carried out positioned at different layers, such as the data block to being partitioned into is carried out in the higher of data group covering Processing, distinguishes different control information and data message, and bag is parsed respectively.

A kind of possible PDU structure is set forth below, as shown in Figure 4.It should be noted that the structure shown in Fig. 4 is A kind of possible implementation, as long as control information and packet can be placed in PDU to the PDU structures for being sent to receiving device It is all suitable for the embodiment of the present invention.

Wherein, the composition of subheader is similar to Example 1, is exactly grown the different data blocks in a logic channel Degree instruction and differentiation, in favor of distinguishing different data blocks.

But inside each data block, and because the type of data block is different, header information can be further divided into and had Imitate two parts of load.

By taking data block 1 as an example, this is the control information of a logic channel level, therefore in header information, first with D/C Domain indicates that this is a control information, and then Type domains are to indicate the type of control information, e.g. feedback of status, still Head compressed feedback etc., it is exactly the effective information part of control information afterwards, it is different according to control information, information lattice can be defined Formula, act in accordance with it.

Wherein：LCID, E, E1 and LI are identical with the implication of embodiment 1, will not be repeated here.

D/C：Control information or data instruction (information for being used for the type of data in data block corresponding to indicating), example It is a control information that such as domain, which takes 0 to represent this, and it is a data to take 1 to represent this, and vice versa, and standard can be prespecified, is received Hair both sides act in accordance with it；

Type：The type (being used for the information for indicating the type of control information) of control information.

By taking data block 2 as an example, this is the data inside a logic channel, therefore in header information, is first come with D/C domains It is a data to indicate this, and the sequence number of this packet is then indicated with follow-up domain, if segmentation, if poll etc. believes Breath, in order to which recipient requires progress shape according to restructuring and sequence of these information to data progress in order, and according to poll State is fed back.Wherein：

SI：Whether be segmented mark (be used for corresponding to indicating in data block whether be segmented data block information), example It is a segment data that such as domain represents this for 1, and it is a complete data packet to take 0 to represent this, and vice versa, and standard can advise in advance Fixed, receiving-transmitting sides are acted in accordance with it；

P：Poll instructions (are used to indicate whether to carry out reception state feedack for corresponding data block), when the domain When being set, represent sender and wish that recipient carries out a reception state feedback as early as possible；

SN：The sequence number of packet, in general, packet can be allocated sequence according to the order received from high level Number, in order to be reordered in receiving terminal according to the sequence number, recombinate and sequentially submit；

LS：Last segmentation instruction (is used for the letter that data block corresponding to indicating is last segmented data block Breath), only when fragmented packets just need the domain, to indicate that the segmentation is that last of Serial No. SN complete data packet is divided Section, after receiving the segmentation, it is believed that Serial No. SN packet receives complete；

SO (is used for the information for indicating original position of the packet in raw data packets in segmented data block)：Segmentation Original position indicates, only when fragmented packets just need the domain, to indicate complete data packet of the segmentation in Serial No. SN The original position of loaded portion.Such as a packet, altogether 500 byte, first segmentation are：0~199, second segmentation It is：200~499.So for first segmentation：SO values are 0, Length Indication 200；For second segmentation：SO values For 200, Length Indication 300.Size is 500 bytes altogether for also for example former SN=5 data packet load part, and this segmentation is Since the 300th byte, then SO values are 300 herein, in conjunction with LI length of the data block in PDU subheaders, if LI is exactly 200, then it is last segmentation of the packet to prove this, positioned at the 300th~500 word of the raw data packets Section.

The scheme of embodiment 3, second of transmission, one logic channel internal data bag.

Similar to Example 2, embodiment 3 also provides a kind of organizational form for being located at a logic channel internal data bag. On control information, data are retransmitted, just pass the priority of data and the tandem of placement, it is consistent with embodiment 2.

In embodiment 3, send equipment head is concentrated on into subheader part, be followed by be all real control information and Data payload portion.

A kind of possible PDU structure is set forth below, as shown in Figure 5.It should be noted that the structure shown in Fig. 5 is A kind of possible implementation, as long as the PDU structures that can be multiplexed are all suitable for the embodiment of the present invention.

It is consistent in the implication and value mode and embodiment 2 and embodiment 1 in each domain in Fig. 5.Difference is to refer on head Show that information concentrates entirely in the header field of forefront, focus on, and the order of header field and follow-up effective information part Order it is completely the same, receiving terminal can parse different control information and data message according to the instruction on head.

Simultaneously as Poll is seeking for the receiving terminal progress to same logic channel, it is not necessary to each packet list Solely carry, can be embodied once on the head of whole logic channel.

It is using control information as an entirety, by the instruction of control information in addition, there is another feasible situation Hold, such as D/C and type also serve as a part for control information, are put together with control information below, and data message is adopted Take Payload and head to indicate separated mode, i.e., take control information the processing mode of embodiment 2, to ensure control letter The integrality of breath, and the mode of embodiment 3 is taken for data division.

Optionally, because embodiment 2 and 3 this data format of embodiment are for retransmitting bag and just passing the support side of packet Formula is consistent, with SN to identify, and also has extra instruction to possible be segmented, such as each data or data point The corresponding block header information of section, so it is to retransmit bag that the data division in above-described embodiment 2 and embodiment 3, which can not have to differentiation, Or just pass packet.

Example IV, the SN to continuous data bag optimize the scheme of processing.

The data of one logic channel are generally divided into three types：Control information, retransmit data and just pass data.For first Data are passed, there is very big optimizable space.Because the SN for just passing data is continuous.That is, just passing data is Transmitted in the way of SN is marked as 0,1,2,3,4,5....So each packet just passed can not have to carry SN, it is only necessary to carry the SN of first packet, the SN of remainder data bag only needs to perform+1 operation in sequence.

Certainly, nor all first biography data are all continuous, the situation of both links transmission is divided under centralized node, Be probably that part is continuous, for example, 0~No. 4,10~No. 15 SN give the transmission of the first paths, 5~No. 9 SN give Article 2 road Through transmission.In this case it is necessary to distinguish 0~No. 4,10~No. 15 carries out continuous processings according to two sections respectively, in addition it is middle Some possible single discontinuous SN.Similarly, in packet is retransmitted, there is also similar situation, and it is to have that may retransmit bag One section of continuous SN's, but also it is not excluded for independent SN situation.Therefore either it is required to for retransmitting data or just passing data Support simultaneously to the optimization processing of continuous data bag and independent SN processing.

A kind of possible PDU structure is set forth below, as shown in Figure 6A.It should be noted that the structure shown in figure A is A kind of possible implementation, as long as the PDU structures that can be multiplexed are all suitable for the embodiment of the present invention.

As shown in Figure 6A, equipment is sent inside a logic channel multiple continuous SN data packet group is dressed up into PDU, this When omission processing can be carried out to SN, that is, think follow-up data block 1 be sequence number be equal to SN values packet, data block 2 Serial No. SN values add 1, the Serial No. SN values of data block 3 add 2, the like, multiple data can be cascaded, until Meet the size of transmission block.

In above-mentioned bag form, data message corresponds to subheader region part, and E1 is supporting with LI, is after this LI for indicating It is no to also have LI, in the data message corresponds to header field part, there are three LI, the big of three data blocks can be corresponded respectively to It is small；Can also be the total size that first LI indicates continuous SN partial datas block, corresponding first data block of second LI, the 3rd Corresponding second data block of individual LI, the size that summation subtracts the first two is exactly the 3rd data block size.

D/C domains are instruction control or data, are data type to consecutive data block value.

C/N domains are indicating that follow-up is independent SN data block, or continuous SN data block, if individually SN, then head instruction is carried out in the way of above-described embodiment 3, if continuous SN, then carry SN marks, and carry FI and refer to Show

FI instructions are or complete indicating whether first block of continuous SN data block portions and last block are segmentations Whole data, if one or two blocks are to be segmented, then the instruction that follow-up SO1 and SO2 are segmented respectively.

For continuous data bag, first and last data sectional are only the possibility to, middle necessarily complete data packet, So just meet continuous principle, further, the segmentation of first data block must be last segmentation of the packet, And last data block must be first segmentation of corresponding data bag, continuous principle is so only.

As shown in Figure 6B, continuous SN example.In force, middle complete SN number can have multiple, this Place only illustrate first be segmentation and last be segmentation situation.

C/N：Continuous SN packets are indicated whether, general 1 bit, represent two ways, one kind is independent SN, and another kind is Continuous SN；

FI：The segmentation situation of first data block and last lattice data block in continuous SN data is represented, general 2 than especially big Small, the first bit shows whether first bag is segmented, the second bit show last bag whether fragmented packets；

SO1：If first data is segmentation, there is a SO, to indicate data of the segmentation in former SN values Original position in bag, if last data is also segmentation, because last segmentation necessarily the first segmentation, start bit Put one and be set to 0, then meaning the segmentation original position of last segmentation herein can omit, and be defaulted as zero.Certainly also do not arrange Except display indicates.

Three data blocks in Fig. 6 B examples, first data block is the byte of segment data block length 450, in former SN=4 Packet in original position be 200 bytes；Second byte of data packet length 400, SN=5；3rd data block is segmentation The byte of data block length 300, original position is 0 byte in former SN=6 data block.This continuous SN can be with continuous SN's Bag form indicates that receiving terminal can parse with errorless.

In above-mentioned group bag form, the Name ＆ Location in each domain is one kind for example, to illustrate a form In need these information to ensure the Name ＆ Location of differentiation packet that can receiving terminal errorless and form, in force domain Change have no effect on function, adjustment that can be appropriate, within the scope of the present invention.

It should be noted that the above embodiment of the present invention institute illustrated example, by taking AM patterns as an example, when data are UM patterns When, except no re-transmission data, and outside the control information of feedback of status type, remaining mode of operation and above-described embodiment It is similar, it is readily applicable to various groups of bag methods listed in each embodiment and will not be repeated here.
