The present invention relates in the wireless system in the random access procedure scheduling identification (RA-RNTI) and determine technology, relate to (LTE in the long evolving system or rather, Long Term Evolution) insert at random in the system in Physical Random Access Channel (PRACH, Physical Random Access Channel) scheduling identification definite method and apparatus, at random insert in collocation method and device and the accidental access method and the device of scheduling identification.
Background technology
In order to face the future, make lasting competitiveness, 3G (Third Generation) Moblie global standards tissue (3GPP) has formally been set up the LTE research project in December, 2004.The formulation starting point of LTE is to guarantee the competitiveness in following 10 years of 3GPP, is promoted from performance, function, cost comprehensively.With respect to 3GPPRelease6, LTE downstream spectrum efficient will improve 3 to 4 times, on be about to improve 2 to 3 times.Can predict, LTE has considerable status in the radio communication in future.
Fig. 1 is the competitive figure of access process at random in the LTE system, as shown in Figure 1, random access procedure in the LTE system comprises: user terminal UE sends random access lead code (Random Access Preamble) by PRACH to base station eNode B, be also referred to as and insert request message at random, be i.e. message m sg1.ENode B sends accidental access response message (Random Access Response) to UE, is also referred to as response message, i.e. msg2.Msg2 is the response to msg1, and in the LTE system, the scheduling identification of msg2 is RA-RNTI (Random Access Radio Network Temporary Identifier).There are one-to-one relationship in RA-RNTI and the msg1 place PRACH resource of being responded, so after UE receives that RA-RNTI with msg1 place PRACH resource correspondence is the dispatch of sign, can handle accordingly.Msg2 sends in the time window behind Msg1.UE sends the predetermined msg3:Scheduled Transmission that spreads news to eNode B.ENode B sends competition decision msg4:ContentionResolution to UE.
Fig. 2 is the uncompetitive flow chart that inserts at random in the LTE system, as shown in Figure 2, the uncompetitive access at random comprises: eNode B sends lead code assignment messages msg0:RA PreambleAssignment at random to UE, and UE is according to sending msg1:Random AccessPreamble to eNode Preamble that B distributes.ENode B sends response message msg2:Random Access Response to UE.The function of msg1 shown among msg1 shown in Fig. 2, msg2 and Fig. 1, msg2 is basic identical.
The LTE system has determined two kinds of frame structures, and every kind corresponding to a kind of dual-mode.
Fig. 3 is the definite a kind of frame structure schematic diagram supported of LTE system, and as shown in Figure 3, the radio frames frame length of this structure is 10ms, comprises 10 subframes, and the subframe of each 1ms comprises two time slots.Frame structure shown in Figure 3 is suitable for the LTE system of mode of frequency division duplexing (FDD, Division Duplex), is designated hereinafter simply as LTE FDD system.
Fig. 4 determines the another kind of frame structure schematic diagram of support for the LTE system, as shown in Figure 4, the radio frames of 10ms is split into the field (half-frame) of two 5ms, and each field comprises the subframe (subframe) of 5 1ms, and subframe 0 and subframe 5 in the radio frames are fixed for up direction.Subframe 1 and subframe 6 comprise three special time slots, and three special time slots are respectively descending special time slot (DwPTS), uplink special time slot (UpPTS) and translation and protection time slot (GP).Frame structure shown in Figure 4 is suitable for the LTE system of TDD mode (TDD, Time Division Duplex) system, is designated hereinafter simply as LTE FDD system.
In the LTE FDD system, determined to exist at most in the subframe 1 PRACH resource at present, its PRACH resource has 16 kinds in the possible configuration of time domain as shown in Table 1:
The PRACH configuration Frame number Subframe numbers PRACH configuration cycle (ms)
0 Idol 1 20
1 Idol 4 20
2 Idol 7 20
3 Each 1 10
4 Each 4 10
5 Each 7 10
6 Each 1，6 5
7 Each 2，7 5

11 Each 3，6，9 3
12 Each 0，2，4，6，8 2
13 Each 1，3，5，7，9 2
14 Each 0，1，2，3，4，5，6，7，8，9 1

Table one
As can be seen, LTE FDD one has 16 kinds of PRACH configuration, and in these 16 kinds of PRACH configurations, maximum PRACH configuration cycle is 20ms, and what for example be numbered that 0/1/2/15 PRACH configuration uses is exactly this cycle.
Different with LTE FDD, in the LTE TDD system, the PRACH resource can only appear among sub-frame of uplink or the uplink special time slot UpPTS, and may have a plurality of PRACH resources in a subframe or a uplink special time slot UpPTS.Fig. 5 is the structural representation of PRACH configuration in the TDD system, as shown in Figure 5, in the UpPTS of the subframe#1 of each radio frames 5 PRACH is set, and according to the frequency position, their numbering is PRACH 1,2,3,4,5 from low to high successively.Fig. 6 is another structural representation of PRACH configuration in the TDD system, as shown in Figure 6,5 PRACH is set in the subframe#2 of each radio frames, and according to the frequency position, their numbering is PRACH 1,2,3,4,5 from low to high successively.
No matter be FDD system or TDD system, for certain sub-district in the real system, can only use a certain PRACH configuration sometime, the actual PRACH configuration information that uses is determined by network side, and notifies UE by system broadcasts.Certain LTE FDD sub-district for example uses to be numbered 2 PRACH configuration (having 1 PRACH in the subframe 7 of even number radio frames) sometime, therefore notifies UE with the numbering 2 of this PRACH configuration by system broadcasts.
The structural representation that Fig. 7 can not be identified for configuration schedules sign in the LTE system, as shown in Figure 7, the response message of the 1st PRACH resource (being PRACH#1) can send in arbitrary subframe of response message send window (the #4 subframe is to the #9 subframe), and the response message of the 2nd PRACH resource (being PRACH#2) can send in arbitrary subframe of response message send window (the #9 subframe is to the #14 subframe).If in the system design, allow the 1st, 2 PRACH resource corresponding to same RA-RNTI, so UE can't distinguish the RA-RNTI that in subframe 9, receives for the dispatch of sign at be which PRACH resource, this has just produced the fuzzy problem of mapping relations between RA-RNTI and the PRACH resource.If above-mentioned situation, will cause UE can't judge correctly whether this response message needs to handle (promptly this response message is whether corresponding is the PRACH that uses when sending msg1 before own), follow-up work can't normally be carried out.

Embodiment
Core concept of the present invention is: the situation that can cause the response message of two PRACH random accessing messages to send in same subframe under some situation, can cause UE can't discern the situation of which PRACH of scheduling identification RA-RNTI correspondence in the response message, the present invention at first determines the configuration cycle (being the number of subframes of the table of comparisons) of RA-RNTI, be the corresponding RA-RNTI of possible PRACH configuration in each subframe in described configuration cycle, being in the system each may PRACH all dispose a unique RA-RNTI and identifies, like this, after UE receives the response at PRACH of base station side, the RA-RNTI that carries by this response can determine the transmission object that responds, and whether corresponding judgment oneself needs to handle this response message.The present invention realizes simply, the non-required phenomenon of response message that UE handles can not occur.Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated.
Fig. 8 is the flow chart of definite method of PRACH scheduling identification during the present invention inserts at random, and as shown in Figure 8, definite method of PRACH scheduling identification may further comprise the steps during the present invention inserted at random:
Step 801: the length of window according to the configuration cycle of PRACH and PRACH response message is defined as the scheduling identification RA-RNTI number that PRACH reserves.This step promptly is to determine the RA-RNTI number reserved in the system, so that all PRACH that dispose in the system can both be identified.Reserve the number of RA-RNTI, closely related with configuration cycle and the length of window of PRACH response message of PRACH in frame, for example for the FDD system, because the PRACH number in each subframe is 1 to the maximum, if the configuration cycle of PRACH is 10 subframes, and the length of window of PRACH response message is when being not more than 10 subframes, reserves 10 RA-RNTI and can identify all PRACH under this PRACH configuring condition fully.
Step 802: set up and reserve the RA-RNTI and the mutual corresponding table of comparisons of PRACH.The table of comparisons of RA-RNTI that this step is set up and PRACH corresponding relation, promptly at first determine the configuration cycle of a RA-RNTI, this cycle is to be unit with the subframe, determine maximum configurable PRACH numbers in interior each subframe of this cycle, be as the criterion with maximum configurable PRACH numbers in each subframe, reserve the RA-RNTI of respective numbers, to set up the one-to-one relationship of configurable PRACH in RA-RNTI and this subframe.This table of comparisons can be used as a reference standard, is written in UE and the network.
For example determined that according to the configuration cycle of PRACH and the length of window of PRACH response message the configuration cycle of RA-RNTI is N, unit is a subframe, and RA-RNTI configuration cycle, interior each subframe numbering was designated as n, (0≤n≤N-1), L is set respectively in each subframe nIndividual separate RA-RNTI, promptly the RA-RNTI that is provided with in the subframe 0 is designated as RA-RNTI 0,0, RA-RNTI 0,1..., RA-RNTI 0, L0-1, the RA-RNTI that is provided with in the subframe 1 is designated as RA-RNTI 1,0, RA-RNTI 1,1..., RA-RNTI 1, L1-1, the RA-RNTI that is provided with among the subframe N-1 is designated as RA-RNTI N-1,0, RA-RNTI N-1,1..., RA-RNTI N-1, LN-1-1The number of the RA-RNTI of She Zhiing is altogether
Figure S2007103085694D00091
L nBe defined as the maximum number of the PRACH that can dispose in the subframe.That is to say,, press the PRACH situation of the maximum number of possible configuration in each subframe, for the corresponding RA-RNTI of these possible PRACH configurations, to realize the unique corresponding relation of PRACH and RA-RNTI for arbitrary subframe of RA-RNTI in configuration cycle.Here, RA-RNTI configuration cycle N is the number of subframes in the table of comparisons.
Should be understood that above-mentioned situation for PRACH configuration RA-RNTI is a kind of last position matching method of summary.Applicable to any configuration of any system (and dual-mode), for example, all be suitable for for LTE TDD system and LTE FDD system.
For LTE TDD system, the number of configuration PRACH mostly is 5 most, promptly above-mentioned L in each subframe nBe 5, and for LTE FDD system, can only dispose a PRACH in each subframe, promptly above-mentioned L nBe 1.The present invention determines the corresponding standard of PRACH and RA-RNTI, in case definite promptly being cured in the relevant criterion of system, with realize arbitrary PRACH all have definite and unique RA-RNTI corresponding with it.
During specific to a certain communication system, can simplify the configured number of RA-RNTI.
For LTE FDD system, the possibility of configuration PRACH is all arranged in each subframe, but can only dispose a PRACH in each subframe at most, therefore, and for the arbitrary subframe in the configuration cycle of RA-RNTI, the RA-RNTI number L that disposes in each subframe nBe 1.In conjunction with the configuring condition of PRACH in the LTE FDD system, the following three kinds of configuring conditions of optional usefulness:
N＝20，L n＝1，(0≤n≤N-1)；N＝10，L n＝1，(0≤n≤N-1)；N＝5，L n＝1，(0≤n≤N-1)。It is emphasized that the number of subframes N in the table of comparisons is according to the configuration cycle of PRACH and common decision of length of window of PRACH response message.If the length of window of PRACH response message is enough short, the value of N is optional must be smaller, and if PRACH configuration cycle hour, also can make the value of N select smallerly, the selection association that these two factors are N is very closely.The present invention attempts to come PRACH all in the tag system with minimum RA-RNTI number.As shown in Table 1, in the FDD system, the configuration cycle of PRACH is 20 to the maximum, consider that the length of window of PRACH response message is generally the length of 3 to 5 subframes, selecting the number of subframes N in the table of comparisons for use is 10, the corresponding RA-RNTI of each subframe, can realize sign to all PRACH, promptly contained PRACH and be configured to arbitrary subframe, system all can select for use unique RA-RNTI corresponding with it, can not produce the phenomenon that a RA-RNTI identifies a plurality of PRACH.Certainly, select the situation of N=20 for use, corresponding with 20 RA-RNTI with PRACH in each subframe, also can realize sign to all PRACH.
Below describe with concrete example.
Fig. 9 is the corresponding relation schematic diagram of PRACH and RA-RNTI in the LTE FDD of the present invention system, as shown in Figure 9, in the LTE FDD system, number of subframes N in the table of comparisons is 20 o'clock (configuration cycle that is RA-RNTI is 20 subframes), each subframe is all corresponding to a RA-RNTI, reserve 20 RA-RNTI values and get final product, among the figure, corresponding one by one with subframe #0 respectively to the PRACH among the subframe #19 with RA-RNTI#0 to RA-RNTI#19.
Figure 10 is another schematic diagram of corresponding relation of PRACH and RA-RNTI in the LTE FDD of the present invention system, as shown in figure 10, in the LTE FDD system, number of subframes N in the table of comparisons is 10 o'clock, each subframe is all corresponding to a RA-RNTI, reserve 10 RA-RNTI values and get final product, among the figure, corresponding one by one with subframe #0 respectively to subframe #9 with RA-RNTI#0 to RA-RNTI#9.
For LTE TDD system,, also just corresponding RA-RNTI needn't be set because it is descending to have stipulated that some subframes can only be used in the agreement, so can not dispose PRACH in these descending sub frames.For the subframe of configurable PRACH, the number of its configuration PRACH mostly is 5 most, can be 0.In conjunction with the configuring condition of the LTE TDD PRACH of system, following several configuring condition is arranged:
N＝5， L n = 0 , ( n = 0 ) 5 , others ( 0 ≤ n ≤ N - 1 ) ; N＝10， L n = 0 , ( n = 0,5 ) 5 , others ( 0 ≤ n ≤ N - 1 ) ; N＝20，
L n = 0 , ( n = 0,5,10,15 ) 5 , others ( 0 ≤ n ≤ N - 1 ) ; N＝5， L n = 5 , ( n = 1,2 ) 0 , others ( 0 ≤ n ≤ N - 1 ) ; N＝10，
L n = 5 , ( n = 1,2,6,7 ) 0 , others ( 0 ≤ n ≤ N - 1 ) ; N＝20， L n = 5 , ( n = 1,2,6,7,11,12,16,17 ) 0 , others ( 0 ≤ n ≤ N - 1 ) .
The present invention determines the table of comparisons of RA-RNTI and PRACH according to the configuration cycle of PRACH and PRACH to the length of window of answering message, with all PRACH that attempt to utilize minimum RA-RNTI, come in the recognition system to be disposed.Certainly, consider the factors such as computing of system, the number of used RA-RNTI suitably gets final product.
Figure 11 is the corresponding relation schematic diagram of PRACH and RA-RNTI in the LTE TDD of the present invention system, as shown in figure 11, in the LTE TDD system, selecting the number of subframes N in the table of comparisons for use is 5 o'clock, wherein for subframe 1,2,3,4, each subframe is configurable 5 PRACH at most, and required RA-RNTI is 20, and therefore reserving 20 RA-RNTI values can identify all PRACH.In the concrete configuration of certain PRACH, determine the RA-RNTI that certain piece PRACH resource is reserved corresponding to its place subframe according to corresponding relation, if there are a plurality of PRACH in the subframe, the corresponding relation of then a plurality of PRACH and RA-RNTI according to the frequency of PRACH resource from high to low (or from low to high) be arranged in order.
Because the number of subframes N in the table of comparisons determined to the length of window of answering message jointly according to the configuration cycle of PRACH and PRACH, when if 20 RA-RNTI are not enough to PRACH that unique identification disposes, can 10ms as configuration cycle of RA-RNTI, among the present invention, the configuration cycle of RA-RNTI is the number of sub frames in the table of comparisons.Thereby at each sub-frame of uplink, it is corresponding with it that 5 RA-RNTI all are set.
Consider the compatibility of system, the present invention proposes a kind of RA-RNTI that is applicable to LTE TDD system and LTEFDD system simultaneously and the PRACH corresponding table of comparisons mutually, as table two:
