How to obtain the parameter information or such as of data to be transmitted in each layer of Wireless Access Unit to transmission device below The parameter information what transmits data to be transmitted to other layers is described in detail.
As an alternative embodiment, each Transmission Time Interval (Transmission Time Interval, TTI) business datum that can be dispatched includes at least one transmission block, i.e., PHY layer in each TTI from the MAC protocol number of MAC layer It is at least one transmission block according to the data to be transmitted obtained in unit (Protocol Data Unit, PDU).Transmission device exists PHY layer obtains the parameter information of data to be transmitted, may include：Transmission device is according to the biography where data to be transmitted in business Defeated channel logo obtains the parameter information of data to be transmitted, wherein different transmission channels identifies corresponding transmission channel and holds Carry the data to be transmitted of different importance rates.
For example, referring to Fig. 3, Fig. 3 is the structural schematic diagram of seed transmission channel provided in an embodiment of the present invention, when every When a TTI scheduling single transmission block, multiple sub- transmission channels can be established in transmission channel, every sub- transmission channel can be held Carry the data to be transmitted of different importance rates.Transmission device puts the highest data to be transmitted of importance rate in MAC layer It is transmitted to being identified as in the highest sub- transmission channel of importance rate, the high data to be transmitted of important level important level time is put It is transmitted to being identified as in the high sub- transmission channel of importance rate time.Transmission device is in PHY layer by reading data to be transmitted Sub- transmission channel mark can obtain the parameter information of data to be transmitted.
For another example when each TTI dispatches multiple transmission blocks, different transmission blocks can carry different importance rates Data to be transmitted, multiple transmission blocks can be transmitted by multiple and different transmission channels.Each transmission channel is different The data to be transmitted of importance rate.For example, the highest data to be transmitted of importance rate is put by transmission device in MAC layer It is identified as in the highest transmission channel of importance rate and transmits；The high data to be transmitted of importance rate time is put into and is identified as It is transmitted in the high transmission channel of importance rate time.Correspondingly, transmission device is by reading transmission channel mark in PHY layer The parameter information for obtaining different importance rates can be obtained.
As another optional embodiment, transmission device obtains the parameter information of data to be transmitted, including：Transmission is set Interlayer primitive between standby preset field or each layer of Wireless Access Unit according in protocol Data Unit, or to the agreement Data cell carries out feature recognition, obtains the parameter information of data to be transmitted.
For example, when the Wireless Access Unit includes PDCP layers of packet data aggregation protocol, transmission device obtains to be transmitted The parameter information of data, including：Transmission device is according to the preset field of data cell in IP layers of Internet protocol, in IP Reserved bit or differentiated services (differentiated services codepoint, DSCP) field in TOS fields, or Described IP layers and it is PDCP layers described between interlayer primitive, or to the data cell carry out feature recognition, obtain number to be transmitted According to parameter information.Correspondingly, at PDCP layers, the importance rate of data to be transmitted can be passed through PDCP protocol data lists The interlayer primitive of the preset field or PDCP of first PDU layer between wireless spread-spectrum technology rlc layer, passes to rlc layer.
For example, referring to Fig. 10, Figure 10 is the structural schematic diagram of PDCP PDU provided in an embodiment of the present invention a kind of, as schemed Shown in 10,3 bit reserved bits in PDCP SN may be used to transmit the importance rate of the PDCP PDU.
In rlc layer, interlayer primitive of the transmission device by the preset field or PDCP of PDCP PDU layer between rlc layer, Or feature recognition is carried out to PDCP PDU, obtain the importance rate of the data to be transmitted of PDCP PDU carryings.
Correspondingly, when the Wireless Access Unit includes wireless spread-spectrum technology rlc layer, the transmission device obtains to be passed The parameter information of transmission of data, including：Transmission device is according to the weight of RLC service data units SDU in rlc protocol data cell PDU The property wanted grade obtains the parameter information of the data to be transmitted carried in the RLC PDU.
Wherein, rlc layer, not plus the PDCP PDU of RLC head information are known as RLC SDU, wherein the RLC specified by MAC layer The size of PDU is usual and is not equal to the size of RLC SDU, and therefore, it is necessary to the modes that RLC SDU are connected or are segmented to generate RLC PDU match the specified size of MAC layer.Therefore, the importance rate of the carried data of RLC PDU defers to its composition The highest importance rate of RLC SDU is principle.For example, RLC PDU are only by an a complete RLC SDU or RLC SDU Part composition, then the importance rate of the RLC PDU be equal to it and form the importance rate of RLC SDU；As RLC PDU by The part of multiple complete RLC SDU or RLC SDU forms, then the importance rate of the RLC PDU is equal to its composition RLC SDU Importance rate highest priority.
It is the structural representation that a kind of RLC SDU provided in an embodiment of the present invention are mapped to RLC PDU to please refer to Fig.1 1, Figure 11 Figure, as shown in figure 11, when RLC SDU are mapped to RLC PDU, SN, which is the RLC SDU of x+1, to be divided into two parts to put respectively It sets in the RLC PDU that SN is n and n+1, it is the RLC of x+3 that the RLC SDU that SN is x, which are placed on the RLC PDU, SN that SN is n, SDU can be divided into two parts to be individually positioned in the RLC PDU that SN is n+1 and n+2, and SN is that the RLC SDU of x+2 are placed on SN is in the RLC PDU of n+1.It is segmented in RLC SDU, a RLC SDU is segmented into multiple RLC PDU, then RLC PDU importance rates are equal to RLC SDU importance rates；In the case of RLC series connection, multiple RLC SDU series connection are a RLC PDU, then the RLC PDU importance rates be equal to it and form the importance of the highest RLC SDU of importance rate in RLC SDUs Grade.For example, being made of the part of SDU x and SDU x+1 in rlc layer PDU n, then the importance rate of PDU n is SDU x And higher importance rate in SDU x+1.In rlc layer, the importance rate of data to be transmitted can be passed through RLC PDU Preset field, as in RLC PDU reserved bit position or rlc layer and MAC layer between interlayer primitive, pass to MAC Layer.
Correspondingly, when the Wireless Access Unit includes media access control MAC layer, the transmission device obtains to be passed The parameter information of transmission of data, including：Transmission device is according to the preset field or Radio Link in Medium Access Control (MAC) Protocol Data Unit PDU The interlayer primitive between rlc layer and the MAC layer is controlled, or feature recognition is carried out to the MAC PDU, obtains number to be transmitted According to parameter information.
Referring to Fig. 4, Fig. 4 is the structural schematic diagram of MAC PDU provided in an embodiment of the present invention a kind of.As shown in figure 4, The payload of MAC PDU is by multiple MAC control elements (Control Element, CE) and MAC Service Data Unit (Service Data Unit, SDU) is formed.Each MAC CE or MAC SDU corresponds to MAC in MAC PDU header informations Head sub-header.Fig. 7 a-7b are please referred to, Fig. 7 a-7b are sub- in a kind of MAC PDU provided in an embodiment of the present invention The structural schematic diagram of header, as shown in Fig. 7 a-7b, R is reserved bit, the reserved bit of the reserved bit in the sub-header For 2bit；E is extension field, which is a flag bit, indicates whether there be other domains in MAC header, if the domains E are set It is set to 1, then it represents that at least another group of the domains R/R/E/LCID thereafter；If the domains E are set as 0, then it represents that from word thereafter It has saved as MAC SDU or MAC Control Element or fills unit；The domains LCID in the sub-header are logic channel LCID Domain identifies each MAC CE, MAC SDU or the corresponding logic channel of filling categorical data；F in the sub-header is Format field indicates the length of corresponding MAC SDU data fields, removes the last one subheader and the corresponding sons of regular length MAC CE Head is outer, and each MAC PDU subheaders include a domain F；L in the sub-header is length field, indicates corresponding MAC SDU Byte number have in MAC PDU subheaders in addition to the last one subheader and the corresponding subheaders of regular length MAC Control Element CE The size in one domain L, the domains L is indicated by the domains F, and when the domains F are 0, L length of field is 7 bits, as shown in Figure 7a；When the domains F are 1, L Length of field is 15 bits, as shown in Figure 7b.
When each TTI dispatches a transmission block, the reserved bit R in sub-header can serve to indicate that corresponding The parameter information of the data to be transmitted of MAC SDU or MAC CE carryings.Optionally, the domains LCID in sub-header can be used In the parameter information for the data to be transmitted for indicating corresponding MAC SDU or MAC CE carryings.Transmission device can be in PHY unit The parameter information of data to be transmitted is obtained by reading the subheader information in MAC PDU.
For example, LCID domain identifiers each utilize the parameter information of the domains the LCID instruction data to be transmitted in sub-header, Then the parameter information of data can be determined according to the value in the domains LCID in each MAC SDU or MAC CE.Specifically, transmission Equipment allows for each MAC SDU's or MAC CE when distributing logic channel to the data in MAC SDU or MAC CE LCID values are associated with the importance rate for the data to be transmitted that the logic channel is carried.For example, some logic channel carrying weight The highest data of the property wanted grade then distribute LCID values according to the rule appointed when to logical channel assignment LCID for it (size of the LCID values of such as logic channel directly proportional to the height of importance rate or inverse ratio), in this way, important with data Property grade meaning LCID values be just recorded in corresponding MAC sub-header, PHY layer, which passes through, reads sub-header LCID values can obtain the parameter information of data to be transmitted.
Optionally, the preset field in addition in sub-header reserved bit and LCID values other than, can also be MAC PDU's First or tail increases additional instruction information, the parameter information of the data to be transmitted carried in instruction MAC PDU, for example, by MAC MAC CE or MAC SDU in PDU sorts according to importance rate, and increased additional instruction information can indicate each importance The length of the data to be transmitted of grade, i.e. boundary information.In this way, transmission device is in PHY layer, so that it may to be believed according to additional instruction It ceases to obtain the parameter information of data to be transmitted.
Correspondingly, when each TTI dispatches multiple transmission blocks, first sub- in MAC PDU where each transmission block Reserved bit indicates the parameter information of the transmission block in header；Alternatively, as described above, also using where each transmission block The head or tail of MAC PDU increases additional instruction information, the parameter information of the data to be transmitted carried in instruction MAC PDU.
In PHY layer, transmission device can be identified according to the transmission channel where data to be transmitted, obtain data to be transmitted Parameter information.Alternatively, transmission device is according to the interlayer primitive between the preset field or MAC layer and PHY layer of MAC PDU, or Feature recognition is carried out to MAC PDU, obtains the parameter information of the data to be transmitted of MAC PDU carryings.
In the embodiment of the present invention, transmission device transmits number to be transmitted according to the configured transmission that parameter information and base station configure According to the configured transmission that can be transmission device configure according to parameter information and base station is that configured transmission, profit is arranged in data to be transmitted The data to be transmitted is transmitted with the configured transmission of setting.Wherein, the configured transmission of base station configuration may include maximum re-transmission time Numerical value, packet data aggregation protocol abandon at least one of timing length, modulation coding scheme index value and scheduling resource. Transmission device is that configured transmission, Ke Yiwei is arranged in data to be transmitted according to the configured transmission that parameter information and base station configure：Transmission Equipment selects configured transmission corresponding with the parameter information of data to be transmitted to transmit data to be transmitted from configured transmission.
For example, the transmission for upstream data, the configured transmission of base station configuration can be multiple maximum retransmission values, then Terminal can be the highest data to be transmitted of importance rate select larger maximum retransmission value, be importance rate compared with Low data to be transmitted selects smaller maximum retransmission value.
For another example the transmission for downlink data, base station is transmitted according to parameter information and configured transmission in data to be transmitted, Base station can be the highest data to be transmitted of importance rate select larger maximum retransmission value, be importance rate compared with Low data to be transmitted selects smaller maximum retransmission value.
Abandoning timing length PDCP discard timer by packet data aggregation protocol of the configured transmission that base station configures is Example.Terminal have at PDCP layers distinguish different importance rate data or and its boundary information ability, terminal can be to base station Reporting has the ability, and the mode reported can be reported by UE-EUTRA-Capability fields.Base station receives terminal After the ability reported, it can determine whether that the terminal enables this ability as needed.Base station can be believed by system The modes such as breath MIB/SIB, PDCCH, RRC signaling, PDSCH MAC CE notify terminal can be to enable the ability.It should be noted that , system information MIB/SIB is the configuration of cell level, and what which enabled is all terminals in cell.
After base station enables the ability, base station can with the Data Radio Bearer of terminal (data radio bearers, DRB it is) that granularity configures multiple PDCP discard timer, multiple PDCP discard timer of configuration is believed by RRC It enables, PDCCH, the modes such as PDSCH, MAC CE are notified to terminal.For example, multiple PDCP that the DRB that base station is terminal is respectively configured Discard timer are 50ms, 100ms, 150ms, then terminal is data to be transmitted setting according to parameter information and configured transmission Configured transmission can be：Importance rate in the DRB is the PDCP discard of the data to be transmitted of Level_1 by terminal Timer is set as 50ms, and importance rate is that the PDCP discard timer of the data to be transmitted of Level_2 are set as 100ms, importance rate are that the PDCP discard timer of the data to be transmitted of Level_3 are set as 150ms.For example, eventually It holds when the discardTimer timings of PDCP SDU expire, the PDCP SDU and corresponding PDCP PDU can be abandoned.
For example, base station enables the not enabled disable terminals abilities of enable/ with RRC signaling to be：
For another example base station notifies the lattice of the configured transmission (PDCP discard timer) of terminal configuration by RRC signaling Formula can be as follows：
By taking the configured transmission of base station configuration is multiple maximum retransmission values as an example, then terminal can be for importance rate most High data to be transmitted selects larger maximum retransmission value, is that the junior data to be transmitted selection of importance is smaller Maximum retransmission value.
For concrete example, terminal reports UE to have for the re-transmission time of different importance rate data separation maximums in MAC layer The ability of number processing, can be the ability that UE is reported by UE-EUTRA-Capability fields.Base station receives the tool of UE , can be as needed after having the ability for distinguishing configuration maximum retransmission, decide whether this ability (base station using the UE Have the ability through the signaling enable/disable terminals abilities, can be by system information MIB/SIB or PDCCH or Person's RRC signaling either modes such as PDSCH MAC CE, it should be noted that system information MIB/SIB is matching for cell level It sets, which enables is all UE in cell).If base station enables the ability, then base station can be that the MAC of counterpart terminal is real Body configures multiple maximum retransmissions, and advice method can be by RRC signaling either PDCCH or PDSCH MAC CE Etc. modes.If base station is that maxHARQ-L1Tx, maxHARQ-L2Tx, maxHARQ-L3Tx is respectively configured in certain terminal, then base station will After the configured transmission of configuration is sent to terminal, terminal is secondary by the maximum re-transmission for the data to be transmitted that importance rate is Level_1 Number is arranged to maxHARQ-L1Tx, and importance rate is that the maximum retransmission of the data to be transmitted of Level_2 is arranged to MaxHARQ-L2Tx, importance rate are that the maximum retransmission of the data to be transmitted of Level_3 is arranged to maxHARQ- L3Tx。
Wherein, can be as follows come the format of the configured transmission (maximum retransmission) of transmission configuration by RRC signaling：
After transmission device receives the above-mentioned configured transmission of base station configuration, so that it may with the biography configured from base station according to parameter information Configured transmission is selected for data to be transmitted in defeated parameter, data to be transmitted is transmitted using selected configured transmission.
It, can be with after transmission device obtains the parameter information of data to be transmitted as it can be seen that in data processing method shown in Fig. 2 The configured transmission configured according to the parameter information and base station is that data to be transmitted configures configured transmission.Therefore, which can While ensureing transmission reliability, to contribute to save Internet resources.
Referring to Fig. 6, Fig. 6 is the flow diagram of another data processing method provided in an embodiment of the present invention, Fig. 6 institutes The data processing method shown is compared with data processing method shown in Fig. 2, the transmission for upstream data, and terminal obtains to be passed After the parameter information of transmission of data, the parameter information or handling result based on the parameter information can also be sent to base station, Specifically, data processing method shown in fig. 6 may comprise steps of：
S201, terminal obtain the parameter information of data to be transmitted；
The parameter information or handling result based on the parameter information are sent to base station by S202, terminal；
S203, terminal receive the configured transmission of base station configuration；The configured transmission is base station according to the parameter information or is based on What the handling result of the parameter information was configured；
S204, terminal transmit data to be transmitted according to parameter information and configured transmission.
In the embodiment of the present invention, terminal can pass through Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH), wireless heterogeneous networks (Radio Resource Control, RRC) signaling, Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) or MAC CE etc. are by the place of the parameter information or the parameter information Reason result is sent to base station.Terminal is that configured transmission is arranged in data to be transmitted, and then utilizes according to parameter information and configured transmission The configured transmission of setting transmits data to be transmitted.
Wherein, the configured transmission of base station configuration may include maximum retransmission value, packet data aggregation protocol discarding timing At least one of duration, modulation coding scheme index value and scheduling resource.It base station can basis for each configured transmission Multiple values are arranged in the handling result of parameter information or parameter information.Terminal is number to be transmitted according to parameter information and configured transmission According to setting configured transmission, Ke Yiwei：Parameter of the terminal from multiple transmission parameter values selection and data to be transmitted in configured transmission The corresponding transmission parameter values of information.
For example, base station is maximum re-transmission time according to the configured transmission that the handling result of parameter information or parameter information configures Number.Terminal can be by parameter information, for example, importance rate Level_1, Level_2, Level_3, are reported to base station, base station It is for the maximum retransmission value that importance rate Level_1, Level_2, Level_3 are respectively configured：maxHARQ-L1Tx、 maxHARQ-L2Tx、maxHARQ-L3Tx；The maximum retransmission of configuration is sent to terminal by base station, then terminal will be all important Property grade be Level_1 data to be transmitted transmit maximum retransmission be set as maxHARQ-L1Tx, make a difference The maximum retransmission that the data to be transmitted that grade is Level_2 is transmitted is set as maxHARQ-L2Tx, and all importance rates are The maximum retransmission of the data to be transmitted transmission of Level_3 is set as maxHARQ-L3Tx.
For another example base station is PDCP according to the configured transmission that the handling result of parameter information or parameter information configures discard timer.Terminal can be that granularity sends the DRB with Data Radio Bearer (data radio bearers, DRB) The parameter information of middle data to be transmitted.For example, there are three the numbers of importance rate Level_1, Level_2, Level_3 for terminal According to；Tri- values of Level_1, Level_2, Level_3 of quantization can be reported to base station by terminal.Optionally, terminal can also incite somebody to action The handling result of parameter information tells base station, for example, base station terminal is told to have the to be passed of 3 kinds of (2bit signalings) importance rates Transmission of data.Wherein, it can be believed by PUCCH, RRC that terminal, which reports the mode of the handling result of parameter information or parameter information, It enables, PUSCH MAC CE etc..After base station receives the parameter information that terminal reports or handling result, so that it may with for each importance Grade configures corresponding configured transmission (for example, PDCP discard timer), and the configured transmission of configuration is sent to end End, which can be by modes such as RRC signaling, PDCCH, PDSCH or MAC CE.
For example, tri- values of Level_1, Level_2, Level_3 of quantization can be reported to base station by terminal, base station is The PDCP discard timer that Level_1, Level_2, Level_3 are respectively configured are 50ms, 100ms, 150ms, are passed through The modes such as RRC signaling, PDCCH, PDSCH or MAC CE are transferred to terminal, and terminal is that importance rate is in the DRB The PDCP discard timer of the data to be transmitted of Level_1 are set as 50ms, and importance rate is the to be passed of Level_2 The PDCP discard timer of transmission of data are set as 100ms, and importance rate is the PDCP of the data to be transmitted of Level_3 Discard timer are set as 150ms.
For another example base station is modulating-coding plan according to the configured transmission that the parameter information is the data to be transmitted configuration Slightly (Modulation and Coding Scheme, MCS) index value or scheduling resource.Terminal is by the important of data to be transmitted Property class information be reported to base station, can be the importance rate for weighing data to be transmitted in uplink buffer, by importance etc. Grade information is added buffer status report (Buffer Status Report, BSR) and tells that base station, existing BSR only include Buffer Size information, importance rate information is added in we, can lie in importance rate in LCG ID, as LCG ID are got over Small expression importance rate is lower, it is specified that the higher Buffer of importance rate is placed on before reporting information when Long BSR It is (rear) end, either by PUCCH, RRC signaling, PUSCH MAC CE (unlike reporting parameter information from BSR, BSR with LCG reports for granularity, and MAC CE can accomplish to report by granularity of logic channel) etc. modes tell base station；Base station receives terminal The importance rate information of data to be transmitted in uplink buffer will when configuring MCS index values or scheduling resource for the terminal Importance rate information is taken into account, for example is provided for the scheduling of the smaller MCS value of the high data configuration of importance rate or more Source ensures accurate delivery.Base station can will consider that the MCS value of importance rate information configuration is placed on the modulating-coding strategy of DCI It is sent to end with redundancy versions (modulation and coding scheme and redundancy version) field End, terminal determine order of modulation (modulation used in corresponding PUSCH transmission according to the MCS value of the field Order), redundancy versions (redundancy version) and transport block size TB size etc. handle data to be transmitted Configured transmission；Wherein, base station will consider that the scheduling resource of importance rate information configuration is placed on DCI and is sent to end by PDCCH End.
