Hereinafter, the present processes embodiment is described in detail in conjunction with Fig. 3 to Figure 12.Below with specific embodiment to this Shen Technical solution please is described in detail.These specific embodiments can be combined with each other below, for same or analogous Concept or process may be repeated no more in some embodiments.It should be understood that Fig. 3 to Figure 12 is the communication means of the embodiment of the present application Schematic flow chart shows the detailed communication steps or operation of this method, but these steps or operation are only example, this Shen Please embodiment the deformations of other operations or various operations in Fig. 3 to Figure 12 can also be performed.In addition, in Fig. 3 to Figure 12 Each step can be executed according to the different sequences presented from Fig. 3 to Figure 12 respectively, and it is possible to not really want to execute All operationss in Fig. 3 to Figure 12.

Fig. 3 shows a kind of method flow schematic diagram sending RLC state reports provided by the embodiments of the present application, this method 300 can be applied to communication scenes shown in FIG. 1, and flow is applied to the Radio Link that terminal device is communicated with RAN equipment described in Fig. 3 Data receiver, comprise the following steps：

301, data receiver construct RLC state reports, the RLC state reports include NACK_SN_RANGE fields and/or The length of RLC state report types, wherein NACK_SN_RANGE fields is variable.

In the embodiment of the present application, the length of the NACK_SN_RANGE fields is used to indicate in RLC state reports The occupied bit length of NACK_SN_RANGE fields；The RLC state report types are used to indicate No includes NACK_SN_RANGE fields.

In the embodiment of the present application, the data receiver that NACK_SN_RANGE is used to indicate to calculate since NACK_SN is complete The number of the number of the RLC data PDU lost entirely or the RLC data PDU of partial loss.NACK_SN_RANGE may include Start sequence number is the RLC data PDU of NACK_SN, can not also include the RLC data PDU that start sequence number is NACK_SN.Terminal The otherness of business feature and Radio Link that equipment is communicated with RAN equipment causes data sending terminal in a transmission time interval The quantity of the RLC data PDU transmitted in (Transmission Time Interval, TTI) may have prodigious difference, such as A small amount of RLC data PDU can only be transmitted for big one TTI of business datum, small one TTI of business datum can be passed Defeated a large amount of RLC data PDU.In addition, when the wireless link channel between terminal device and RAN equipment is of poor quality, data hair Sending end is few many when the quantity for the RLC data PDU that a TTI is transmitted is also better than quality of wireless channel.Terminal device and RAN The Radio Link of equipment communication has fading characteristic and time variation, and in some cases, the radio link quality is in a short time Severe exacerbation, such as the vehicle that the Radio Link is moved stop, cause data receiver to detect and lose data sending terminal hair The a large amount of continuous RLC data PDU sent, therefore can be arranged NACK_SN_RANGE field values larger for data receiver, needs In RLC state reports NACK_SN_RANGE is indicated using more bit number；In other cases, the Radio Link matter After amount is restored, data receiver detects that the RLC data PDU that the data sending terminal of loss is sent greatly reduces, therefore number It is smaller that NACK_SN_RANGE field values can be set according to receiving terminal, need to carry out table using less bit mesh in RLC state reports Show NACK_SN_RANGE.Illustratively, when radio link quality is poor, 10 bit lengths can be used to carry out table for data receiver Show NACK_SN_RANGE, i.e., can accommodate the state at most continuously losing 1024 RLC data PDU in a RLC state report Instruction；When radio link quality is preferable, 4 bit lengths can be used to indicate NACK_SN_RANGE, i.e., one in data receiver The state instruction at most continuously losing 16 RLC data PDU can be accommodated in a RLC state reports.Particularly, data receiver is also May be provided in RLC state reports does not include NACK_SN_RANGE fields, this is equivalent to data receiver and determines NACK_SN_ The length of RANGE fields is zero bit.

In one example, data receiver can receive the reception RLC data PDU before sliding window according to current RLC The case where, such as the situation that multiple RLC early period receive the RLC data PDU lost in sliding window is counted, it determines in current RLC Receive the length of the NACK_SN_RANGE fields in the RLC state reports corresponding to sliding window；Further, data receiver End may also be combined with current radio link quality to determine the length of NACK_SN_RANGE fields.In another example, data are sent out Sending end can send the configuration information to the length of NACK_SN_RANGE fields to data receiver, by data receiver according to this Configuration information determines the length of NACK_SN_RANGE fields.

Optionally, data receiver can further determine that the type of the RLC state reports.For example, if the RLC state reports Announcement includes NACK_SN_RANGE fields, then it is believed that the RLC state report types are the RLC state reports of NR；If the RLC State report does not include NACK_SN_RANGE fields, then it is believed that the RLC state report types are the RLC state reports of LTE.

Illustratively, Fig. 4 (a) shows that data receiver receives reception of the sliding window to RLC data PDU in current RLC Situation；Fig. 4 (b) shows the format with the RLC state reports corresponding to the RLC data PDU reception conditions.In this example, from Fig. 4 (a) is as it can be seen that data receiver detection in current RLC receives sliding window has received eight RLC numbers of the serial number from n to n+7 According to PDU, what data receiver detected is lost two sections of RLC data PDU, and wherein first segment is the RLC data from n to n+2 PDU, second segment are the fore-end RLC data PDU of the rear end part of n+4, n+5, n+6 and n+7；Data receiver is correct Receive front end (byte offset location from 0 to 159) part RLC data PDU's and n+7 of RLC the data PDU and n+4 of n+3 Rear end (byte offset location from 88 to tail portion) part RLC data PDU；The RLC data PDU of n+8 is that data receiver is next The RLC data PDU not received.Correspondingly, in RLC status report format schematic diagrames 4 (b), data receiver uses NACK_ Bit number corresponding to the length of SN_RANGE fields indicates NACK_SN_RANGE fields.In this example, data receiver Determining that the length of NACK_SN_RANGE fields is 3 bits, therefore in Fig. 4 (b), NACK_SN_RANGE fields occur twice, Corresponding instruction is detected as the two sections of RLC data PDU lost respectively, and each NACK_SN_RANGE fields occupy the length of 3 bits Degree.It should be understood that RLC states in definition and the LTE protocol in Fig. 4 (b) in addition to other unexpected fields of NACK_SN_RANGE fields The definition of field in report is identical.

Optionally, in the case where needing and the RLC state report types of LTE protocol are distinguished, for example, NR systems both Can use includes that NACK_SN_RANGE fields can also be using the RLC state reports for not including NACK_SN_RANGE fields In the case of, in order to distinguish the RLC state reports that the RLC state report types including NACK_SN_RANGE fields are NR rather than The RLC state reports of LTE can be distinguished in a kind of example by the value of the CPT fields in RLC state reports.? In the RLC state reports of LTE, CPT field values are that " 000 " indicates that RLC controls PDU is RLC state reports, and CPT fields take Value is that " 001 " to " 111 " is reserved.In the embodiment of the present application, it can be used that the CPT's of RLC controls PDU in LTE protocol is reserved CPT words can be arranged as shown in table 1 to indicate that the RLC state report types are the RLC state reports of NR in any one in value Section value is " 001 " to indicate that the RLC state report types are the RLC state reports of NR；When the CPT words in RLC state reports Section value still indicates that the RLC state report types are the RLC state reports of LTE when being " 000 ".It is worth noting that, in NR systems When in system without using the case where not including the RLC state reports of NACK_SN_RANGE fields, then it can retain CPT field values Indicate that the RLC state reports are the RLC state reports of NR for " 000 ".It, can be by RLC state reports in another example In increase newly second field to distinguish the RLC state reports that the RLC state report types are NR or LTE.As shown in figure 5, Increase by second field (E3 fields are identified as in figure) in RLC state reports, which may be configured as 1 bit length Binary variable further as shown in table 2, when E3 field values are " 0 ", may indicate that the RLC state report types are The RLC state reports of LTE may indicate that the RLC state report types are the RLC state reports of NR when E3 field values are " 1 " It accuses.In Figure 5, E3 fields value is " 1 ", then has NACK_SN_RANGE fields to follow behind its corresponding NACK_SN；Explanation The RLC state report types are the RLC state reports of NR.It should be understood that specific location of the E3 fields in RLC state reports is can Choosing, this is not construed as limiting herein.
