Description
Technical field
The present invention relates to communication technical field, particularly to Stochastic accessing wireless network under a kind of coverage enhancement scene
Network temporary mark (Random Access Radio Network Temporary Identifier, RA-RNTI)
Determination method and apparatus.
Background technology
Competition Stochastic accessing refer to base station (eNodeB, eNB) be not terminal (User Terminal, and
Claim user equipment, User Equipment, UE) distribution private resource, completely by terminal random initiate with
Machine access procedure.Competition Stochastic accessing is applied to all five kinds of scenes, for RRC connection establishment, RRC
Connection reconstruction and the scene of upstream data arrival, Stochastic accessing is entirely spontaneous by terminal, and eNB does not appoint
What prior information；Scene is reached for switching and downlink data, terminal is initiated to connect at random according to eNB instruction
Enter, it is, in general, that the eNB meeting non-competing Stochastic accessing of prioritizing selection, only in non-competing random access resource
In the case of not distributing, just instruction terminal can initiate competition Stochastic accessing.Competition random access procedure divides four
Step completes, as shown in figure 1, each step be referred to as a piece of news (Message), in relevant criterion by this four
Individual step is referred to as Msg1～Msg4.Wherein：
Msg1：Leading (preamble) sequence.
This message is upstream message, is sent by terminal, and eNB receives, and is carried on Physical Random Access Channel
Send in (Physical Random Access Channel, PRACH).For competition Stochastic accessing, whole
The preamble sequence that end sends is randomly choosing in specific preamble set, different
Preamble sequence there are different identification informations, i.e. preamble index (index).
Msg2：Accidental access response (Random Access Response, RAR).
This message is downstream message, is sent by eNB, and terminal receives.
Msg2 be eNB after receiving Msg1 to terminal initiate Stochastic accessing response it is necessary to
Send in accidental access response window.Accidental access response window starting point is to meet first available descending son of n+3
Frame, last subframe that n sends for preamble sequence, length is 2～10ms, by eNB in system
Specify in message.
Msg2 medium education (Media Access Control, MAC) layer define descending shared
Channel (Downlink Shared Channel, DL-SCH) carries, and shares in the corresponding physical down of physical layer
Channel (Physical Downlink Shared Channel, PDSCH).Article one, Msg2 can respond multiple
The random access request of terminal, carries the hungry RAR of multiple terminals simultaneously, and therefore Msg2 does not mix certainly
Dynamic repeat requests (Hybrid Automatic Repeat reQuest, HARQ) process, that is, do not have repeat request
Process.
Random access radio network temporary mark (the Random by transmission in public search space for the eNB
Access Radio Network Temporary Identifier, RA-RNTI) physical down that scrambles controls letter
Road (Physical Downlink Control Channel, PDCCH) dispatch Msg2, RA-RNTI by send out
The PRACH running time-frequency resource position sending Msg1 determines；Terminal meter using identical PRACH running time-frequency resource
Calculation obtains identical RA-RNTI, and its RAR information package sends in same RAR message, this RAR
Message bearing transmits in the DSCH Downlink Shared Channel of the PDCCH scheduling being scrambled by this RA-RNTI, and should
DSCH Downlink Shared Channel is also scrambled using this RA-RNTI.
Content in Msg2 includes：Backoff (rollback) parameter preamble sequence corresponding with Msg1
Row identification information, uplink Timing Advance (TA), Msg3 uplink scheduling license (UL grant,
Be also called RAR grant in physical layer), interim (Temporary) cell-level Radio Network Temporary Identifier (Cell-
Radio Network Temporary Identifier, C-RNTI), abbreviation TC-RNTI.Wherein, backoff
If parameter is used for indicating this random access failure, terminal initiates the time delay average of Stochastic accessing next time.
Terminal passes through the PRACH time-frequency domain resources being used from transmission preamble sequence in Msg1
The RAR message that the RA-RNTI identification determining carries itself RAR (sends in DL-SCH
Msg2), according to the mark letter from the preamble sequence sending in Msg1 in this RAR message
Breath determination is sent to the RAR of oneself.If terminal is not properly received RAR, according to backoff
The time delay of parameter limits and determines the time delay next time initiating Stochastic accessing, in addition selects random access resource to initiate
Stochastic accessing next time.After reaching largest random access number of times, terminal mac layer reports to rrc layer at random
Access problem, triggers Radio Link Failure (Radio Link Failure, RLF) process.
Msg3：First time scheduling of upstream transmissions.Terminal after receiving Msg2, obtain itself
Carry out uplink on the ascending resource indicated by UL grant (i.e. RAR grant) included in RAR,
I.e. according to transmitting scheduling information Physical Uplink Shared Channel (the Physical Uplink in the RAR grant of itself
Shared Channel, PUSCH), the Uplink Shared Channel (Uplink of the corresponding MAC layer of this PUSCH
Shared Channel, UL-SCH).
Msg4：Contention resolved.ENB and terminal complete final contention resolved by Msg4.Msg4's
Content is corresponding with the content of Msg3.
With the rise of Internet of Things, in long evolving system (Long Term Evolution, LTE) system
Middle support machine type communication (Machine Type Communication, MTC) is increasingly taken seriously.
The physical layer set up the project for MTC in 3GPP Release 13 strengthens project.One MTC device (
Referred to as MTC terminal) it is likely to be of multiple machines and machine (Machine to Machine, M2M) communication
Part of properties in characteristic, such as Hypomobility, transmitted data amount is little, insensitive to communication delay, require pole
Low-power consumption etc..
In existing network, operator finds the terminal working under some scenes, such as works in basement, business
Field or the terminal in building corner, because wireless signal is seriously blocked, signal is subject to very big decaying, no
Method is communicated with network, and is directed to and carries out the depth covering of network under these scenes and can greatly increase network
Networking cost.Through test it is believed that needing to carry out a certain degree of enhancing to existing covering.Realize covering and increase
By force, a kind of more feasible method is using repeating transmission or similar techniques to existing channel, permissible in theory
By carrying out to existing physical channel tens times to hundreds of time repeating the transmission a certain degree of covering gain of acquisition.
When carrying out coverage enhancement transmission, in order to improve transmission performance, Physical Random Access Channel (Physical
Random Access Channel, PRACH) need to carry out transmission is repeated several times.The different covering of correspondence
Strengthen target, define different coverage enhancement grades (level).Different coverage enhancement grades is corresponding not
Same iterative transfer times.Therefore, base station needs clearly to know the coverage enhancement grade of terminal, could basis
The corresponding iterative transfer times of coverage enhancement grade of this terminal receive and merge preamble sequence.Therefore,
Need to distinguish in terms of these three from PRACH time-domain resource, frequency domain resource and preamble sequence different
Coverage enhancement grade.For example, in system exist 4 coverage enhancement grades, respectively level0, level1,
Level 2, level 3, wherein level0 represents not to be needed to carry out coverage enhancement, then first kind of way can be adopted
With time division multiplex (Time Division Multiplexing, TDM) mode, that is, to level0, level 1,
Level 2, level 3 configure the different subframes that can be used for transmission PRACH；The second way can adopt
Frequency division multiplexing (Frequency Division Multiplexing, FDM) mode, that is, to level0,1,2,
What 3 configurations were different can be used for transmitting frequency domain resource (Physical Resource Block (the Physical Resource of PRACH
Block, PRB) position difference)；The third mode can adopt code division multiplexing (Code Division
Multiplexing, CDM) mode, different preamble sequences are configured to level0,1,2,3 and wait
Selected works close.Certainly, above-mentioned three kinds of modes can be combined with using.
In Msg2, the carrying Msg2's of use RA-RNTI corresponding to different level scrambling is descending
Control channel iterative transfer times are different, and the down control channel of this RA-RNTI scrambling is carried
The iterative transfer times of Msg2 are also different to different level, accordingly, it would be desirable to distinguish the scheduling of different level
Information.But according to prior art, when the PRACH time-frequency domain resources using different level are identical (for example
Distinguish different level only with CDM mode), due to RA-RNTI only with terminal use PRACH when
Frequency domain resource is related, therefore, the corresponding RA-RNTI of different level identical it is impossible to distinguish different level
The corresponding Msg2 of terminal.
Content of the invention
Embodiments provide a kind of determination method and apparatus of RA-RNTI, for solving existing skill
Because RA-RNTI is only related to the PRACH time-frequency domain resources that terminal uses in art, lead to different coverings
The enhancing corresponding RA-RNTI of grade is identical it is impossible to the terminal distinguishing different coverage enhancement grades is corresponding
