Description
Technical field
The present invention relates to a kind of mobile communication field more particularly to accidental access method, base station and user equipmenies.
Background technology
With the fast development of information industry, especially from mobile Internet and Internet of Things (IoT, internet of
Things increased requirement) brings unprecedented challenge to future mobile.Such as according to International Telecommunication Union ITU
Report ITU-R M. [IMT.BEYOND 2020.TRAFFIC], it is contemplated that arrive the year two thousand twenty, mobile service amount increases opposite
(the 4G epoch) in 2010 will increase nearly 1000 times, and UE (User Equipment, user equipment) connection numbers also will be more than 17,000,000,000,
As the IoT equipment of magnanimity gradually penetrates into mobile communications network, connection number of devices will be more surprising.In order to cope with this preceding institute not
Some challenges, communications industry circle and academia have expanded extensive 5th third-generation mobile communication technical research (5G), towards
The year two thousand twenty generation.At present in the frame and whole mesh that future 5G is discussed in the report ITU-R M. [IMT.VISION] of ITU
Mark, wherein the demand prospect, application scenarios and every important performance indexes to 5G elaborate.For the new need in 5G
It asks, the report ITU-R M. [IMT.FUTURE TECHNOLOGY TRENDS] of ITU provide the technological trend correlation for 5G
Information, it is intended to solve throughput of system be obviously improved, user experience consistency, autgmentability with support IoT, time delay, efficiency, at
The prominent questions such as sheet, network flexibility, the support of emerging service and flexible spectrum utilization.
Random access (Random Access) process is the important step in wireless communication system, between UE and base station
Establish the ID etc. that down-going synchronous and uplink synchronous and base station distribute user for identification for UE.Initial access and random access
Performance directly influence the experience of UE.Wherein, for traditional wireless communication system, in LTE and LTE-Advanced,
Random access procedure is applied to such as to establish that initial link, cell switching, to re-establish uplink, RRC connection reconstructions more
A scene, and it is divided into random access (Contention-based competition-based according to the whether exclusive leader sequence resources of UE
Random Access) and based on non-competing random access (Contention-free Random Access).Due to base
In the random access of competition, each UE is selected during attempting to establish uplink from identical leader sequence resources
Select targeting sequencing, it is possible that multiple UE select identical targeting sequencing to be sent to base station, therefore Conflicts management strategy be with
How important research direction in machine access, reduce collision probability, how quickly to solve the conflict having occurred and that, is to influence at random
The key index of access performance.
It is divided into four steps generally, based on the random access procedure of competition, as shown in Figure 1.Between random access procedure starts,
The configuration information of random access procedure is sent to user by base station, and user carries out random access mistake according to the configuration information received
Journey.In the first step, user randomly chooses a targeting sequencing from leader sequence resources pond, is sent to base station.Base station is to receiving
Signal carries out correlation detection, to identify the targeting sequencing transmitted by user.In second step, base station sends random to user
Access response (Random Access Response, RAR), including random access leader sequence identifier, according to user and base
Timing advance instruction, Temporary Cell Radio Network temporary identifier (Temporary Cell- determined by time delay estimation between standing
Radio Network Temporary Identifier, TC-RNTI), and by user uplink distributes next time when
Frequency resource.In third step, user sends Article 3 message (Msg3) according to the information in RAR, to base station.Include to be used in Msg3
The information such as user terminal identification and RRC linking requests, wherein the user terminal identification is that user is unique, for solving punching
It is prominent.In 4th step, base station sends Conflict solving mark to user, contains the user terminal identification won in Conflict solving.With
Family upgrades to Cell Radio Network Temporary Identifier/Identity, Cell-RNTI after the mark for detecting oneself, by Temporary Cell Radio Network temporary identifier
(Cell-Radio Network Temporary Identifier, C-RNTI), and ack signal is sent to base station, it completes random
Access procedure, and wait for the scheduling of base station.Otherwise, user starts new random access procedure after being delayed at one section.
It should be noted that in above-mentioned second step, random access response is sent in Physical Downlink Shared Channel.It is sending
During, base station uses random access radio network temporary identifier (Random Access-Radio Network
Temporary Identity, RA-RNTI) the corresponding Physical Downlink Control Channel of Physical Downlink Shared Channel is scrambled.
Random access radio network temporary identifier is corresponded with the transmitted running time-frequency resource occupied of the targeting sequencing that base station detects.
In this case, user can calculate corresponding random access radio network temporary identifier, and descramble physics using the mark
Down control channel, to further detect random access response.
For that can be that user's distribution is leading since base station known users identify based on non-competing random access procedure
Sequence.Therefore when user leads sequence before sending, sequence need not be randomly choosed, and the targeting sequencing distributed can be used.Base
It stands after detecting the targeting sequencing distributed, corresponding random access response, including timing advance and ascending resource can be sent
The information such as distribution.After user receives random access response, it is believed that uplink synchronous is completed, waits for the further scheduling of base station.
Therefore, it is initially accessed and based on non-competing random access procedure only comprising two steps：Step 1 is to send targeting sequencing；Step
Rapid two be the transmission of random access response.
Millimetre-wave attenuator is the possible a key technologies of 5G.By improving carrier frequency to millimeter wave frequency band, band can be used
Width will greatly increase, therefore can greatly improve the transmission rate of system.It declines for height in confrontation millimeter wave band wireless channel
It falls, the characteristics such as high loss, millimeter-wave communication system generally uses wave beam forming (Beamforming) technology, i.e., by using adding
Beam energy is concentrated on a direction by weight factor.When carrying out wireless communication, base station is searched out with user by modes such as polls
Optimal wave beam pair, to maximize the received signal to noise ratio of base station side and user side.User and base when due to establishing initial link
The direction of optimal beam pair is stood and is unaware of, therefore random access is faced with great challenge in millimeter-wave communication system.
In order to obtain the launching beam figuration direction of user terminal, a kind of possible mode is as follows：User sends in the first step
The targeting sequencing stage attempts to send all possible wave beam by way of traditional polled or difference poll, and base station is believed according to reception
The infomation detections such as number intensity go out optimal launching beam excipient direction, and assign optimal beam in second step random access response
The instruction in type direction is sent to user.
In currently existing scheme, generally by the mode of explicit instruction (Explicit Indication) by instruction
User's launching beam number, launching beam index or launching beam deviation of directivity index are directly included in random access response and send out
Give user.In this case, random access response is on the basis of having content, it is necessary to increase additional bit to pass
The beam information of defeated above-mentioned instruction.When user's launching beam excipient direction quantity is larger, corresponding random access response expense
It will obviously increase, reduce system performance.In addition, when the launching beam direction total amount difference of different user, different user pair
The random access response answered needs increased bit number also to differ.In this case, if being sent for different users different
The random access response of length, signaling overheads will significantly increase；If sending the random of equal length for different users to connect
Enter response, although signaling overheads will not be significantly affected, the length of random access response must be with launching beam direction
The maximum user of total amount is reference, and for launching beam direction total amount, smaller user is unnecessary, causes resource overhead will
It can further increase.
