The embodiment introduced in above example is illustrated with multiple citings below：

Example 1：

The citing, it is illustrated with downlink data transmitting procedure：

As shown in figure 4, illustrated by taking three layer protocol stack architecture as an example.L3 protocol layers have pre- under three layer protocol stack architecture First fragmentation feature, and can also possess head compression and peace congruous function.It is of course also possible to by head compression and safety related functions One protocol layer L4 on L3 of generation is individually extracted, such protocol stack structure has reformed into four layer protocol stacks.By This patent content to be protected is had no effect in four layer protocol stacks or three layer protocol stacks, therefore here only with three layer protocol stack knots It is introduced exemplified by structure.Under four layer protocol Rotating fields, description below is equally applicable.

In Fig. 4, the L3 protocol layers of the network equipment are to perform the descending protocol layer being previously segmented into, the L2 agreements of the network equipment Layer is the protocol layer for performing descending scheduling.

Downlink data transmission process under the protocol stack structure is as follows：

The L3 protocol layers of the network equipment determine section length and notify the L2 protocol layers of the network equipment；

The L3 protocol layers of the network equipment determine descending section length first.Initial downlink section length can be an acquiescence Value, such as protocol conventions or based on default configuration.Follow-up descending section length can be adjusted dynamically.The dynamic of section length is adjusted It is whole to be based on one of following information or combination：

The network equipment performs pre-staged protocol layer to user terminal and indicates desired pre-staged length；

The uplink signal-channel quality that user terminal physical layer performs the protocol layer feedback terminal of staged operation to user terminal is believed Breath；

The feature of downlink business corresponding to user terminal, such as data package size；

For example reduce section length when user terminal channel quality is deteriorated；When user equipment downlink service feature changes, than Such as business packet change greatly, then section length is increased.

The L3 protocol layers of user terminal notify the section length of determination the L2 protocol layers of the network equipment, so as to the network equipment L2 agreements strange scheduler when carrying out resource allocation, the resource of distribution can preferably match with section length, to reduce Padding sizes, lift resource utilization.

The L3 protocol layers of the network equipment perform staged operation, wherein, the L3 protocol layers of the network equipment perform staged operation, tool Body has following three kinds of modes：

First, it is segmented in strict accordance with section length, it is allowed to which previous SDU and the latter SDU data are concatenated, raw The PDU for meeting pre-staged length requirement into one.For last PDU, it is allowed to there is padding.

2nd, it is segmented in strict accordance with section length, does not allow previous SDU and the latter SDU data to be concatenated. When a SDU last segmentation be unsatisfactory for pre-staged length when addition padding supply pre-staged length.

3rd, be previously segmented under normal circumstances according to section length, but it is some in particular cases, it is allowed to true segmentation Length be more than or less than predetermined section length, concrete condition includes one of following or all：

Do not allow SDU to concatenate, thus when a SDU after segmentation if SDU afterbody remainders length be less than it is advance The pre-staged length determined, then can be individually created a PDU.

Do not allow SDU to concatenate, thus when a SDU after segmentation if SDU afterbody remainders are individually created one PDU header overhead is more than data division, then allows the partial data and its previous segment data merging one PDU of generation.

For mode one, due to supporting segmentation and concatenation, its head design can at least include following instructions field.Certainly such as Fruit tundish contains multiple continuous SN, it is convenient to omit to the number and length of middle SN instruction, the only middle SN of instruction.Such as： Head can include following content：

SN instructions field (SN) corresponding to data division；

Offset (SO) and length (L) of the data corresponding to first SN in SDU corresponding to the SN；

Data length (L) corresponding to other SN；

Configured information (E), for indicating that SN is followed by data or next SN information.

For mode two and three, due to only supporting to be segmented, do not support to concatenate, therefore situation design comparison is simple, can be only Including following content：

SN instructions field (SN) corresponding to data division

Configured information (E), for indicating that SN is followed by data or SN Length Indication information.

After the L3 protocol layers of the network equipment complete segmentation, the data after segmentation can be delayed in the L3 protocol layers of the network equipment Deposit, the L2 protocol layer buffers of the network equipment can also be issued to.

The L2 protocol layers of the network equipment perform descending scheduling operation, wherein, the L2 protocol layers of the network equipment can be from net After the section length configured information that the L3 protocol layers of network equipment obtain, descending scheduling is performed, resource allocation is as far as possible and whole during scheduling Several pre-staged length match, and can so reduce padding resource sizes as far as possible, lift resource utilization.

The L2 agreement layer tissue PDU of the network equipment, i.e., generate PDU by segment data.Such as：The L2 protocol layers of the network equipment After determining schedule information, the number of segmentation is chosen from the caching of the L3 protocol layers of the network equipment or the L2 protocol layers of the network equipment According to being concatenated and being multiplexed, PDU is generated.

The network equipment carries out downlink data transmission, such as：The L2PDU organized is issued to by the L2 protocol layers of the network equipment The L1 protocol layers of the network equipment carry out downlink data transmission.

The network equipment carries out downlink data HARQ (ARQ, Auto Repeat reQuest) and retransmitted.If through Hybrid automatic repeat-request (HARQ, Hybrid Automatic Repeat reQuest) re-transmission is crossed, terminal is still not able to just Really receive the downlink data that network is handed down to terminal, then just need the ARQ for carrying out downlink data to retransmit, the L2 of the network equipment The fragment size of L3 protocol layer of the layer based on the network equipment distributes resource for downlink retransmitted data, and ARQ, which retransmits data, does not allow weight Segmentation.

The L3 protocol layers of user terminal determine up section length first.Wherein, the pre-staged length of initial uplink can be One default value, such as protocol conventions or based on default configuration.The pre-staged length of subsequent upstream can be adjusted dynamically.It is pre-staged Length can be determined to notify terminal by network, can also voluntarily determined by terminal.Determine that pre-staged length can be based on following letter One of breath or combination：

The desired pre-staged Length Indication information of the network equipment；

The desired pre-staged Length Indication information of user terminal；

The uplink signal-channel quality information of terminal；

The feature of uplink service corresponding to terminal, such as data package size；

For example pre-staged length is reduced when terminal channel quality is deteriorated；When user equipment downlink service feature changes, such as Business packet becomes big, then increases pre-staged length.

In addition, the length that is previously segmented into of the L3 protocol layers of user terminal needs to notify the L2 protocol layers of the network equipment, so as to When the L2 protocol layers scheduler of the network equipment carries out resource allocation, the resource of distribution can preferably match with pre-staged length, To reduce padding sizes, resource utilization is lifted.

If determining the section length of the L3 protocol layers of user terminal by the network equipment, handed over by the network equipment by inside Mutual mode notifies the L2 protocol layers of the network equipment；If determining the section length of the L3 agreements monster of user terminal by user terminal, Then by user terminal by signaling the L2 protocol layers of the network equipment.

The L3 protocol layers of user terminal perform staged operation, wherein, the L3 protocol layers of user terminal perform pre-staged operation, Specifically there are following three kinds of modes：

First, it is segmented in strict accordance with pre-staged length, it is allowed to previous SDU and the latter SDU data are concatenated, Generate a PDU for meeting pre-staged length requirement.

SN instructions field (SN) corresponding to data division；
