Description
Technical field
The present invention relates to wireless communication technology fields, method and base station equipment more particularly, to a kind of random access,
User equipment.
Background technology
With the fast development of information industry, the increased requirement from mobile Internet and Internet of Things is to future mobile communications
Technology brings unprecedented challenge.Present communications industrial circle and academia are carrying out extensive 5G (the 5th third-generation mobile communications
System) technical research, it is intended to solve throughput of system be obviously improved, user experience consistency, autgmentability with support Internet of Things, when
Prolong, efficiency, cost, network flexibility, emerging service and the problems such as flexible spectrum utilization.
Random access (Random Access, RA) process is that user side is communicated with network side foundation in wireless communication system
The important step of link establishes uplink synchronous for UE (User Equipment, user equipment) between base station and base station is
UE distributes the ID etc. of user for identification.The performance of random access directly affects the experience of user.Traditional wireless communication system,
In LTE, LTE-Advanced, random access procedure is applied to establish initial link, cell switching, re-establishes uplink
It connects, the scenes such as RRC connection reconstructions.According to the whether exclusive leader sequence resources of UE, random access procedure can be divided into based on competition
Random access (Contention-based Random Access) and based on non-competing random access
(Contention-free Random Access).For based on non-competing random access procedure, UE is specified using base station
Targeting sequencing (i.e. exclusive targeting sequencing) sends random access request.For random access procedure competition-based, in UE not only
Leader sequence resources are accounted for, each UE selects leading sequence when attempting to establish uplink from identical leader sequence resources pond
Row, and random access request is initiated to base station using selected targeting sequencing, thus there are multiple UE selections are identical leading
Sequence initiates the possibility of random access to base station.Therefore, Conflicts management strategy is the key that random access performance quality.

The characteristics such as high decline, high loss in road, millimeter-wave communication system generally uses wave beam forming (Beamforming) technology, i.e., logical
It crosses and uses weighted factor, beam energy is concentrated on into a direction.When carrying out wireless communication, base station passes through the modes such as poll with UE
Optimal wave beam pair is searched out, to maximize the received signal to noise ratio of user side.UE and base station and do not know when being connected due to establishing
Know the direction of optimal beam pair, therefore the random access procedure in millimeter-wave communication system is faced with great challenge.It is existing
In millimetre-wave attenuator random access procedure, for there are wave beam reciprocity and there is no wave beam reciprocity the case where, separately design
Different flows and channel architecture, but before random access procedure progress, base station can not know the wave beam reciprocity of UE
Situation, therefore can not directly be that UE selects suitable random access channel resource subset structure and access process, cause UE with
Machine access performance declines, and affects the success rate of random access and the experience of user.

The communication system of present embodiment works in high band (such as millimeter wave frequency band) environment, in order to ensure to cover
Lid rate, communication system use beamforming technique, base station and UE using the wave beam being mutually matched to obtaining beam forming gain, with
Overcome path loss larger under high band.The accidental access method of present embodiment can be applied to it is competition-based with
Machine access procedure or based on non-competing random access procedure.
Referring to Fig. 1, present embodiment random access configuration method includes the following steps:
Step 101, random access resource configuration information is determined, which includes for having wave
The random access resource information of beam reciprocity UE and for the random access resource information without wave beam reciprocity UE;
Step 102, the random access resource configuration information is sent to UE, to allow UE according to itself wave beam reciprocity disposition
Condition and the random access resource configuration information select corresponding random access resource to send the random access for including targeting sequencing
Request.
Referring to Fig. 2, present embodiment random access request method includes the following steps:
Step 201, the random access resource configuration information that base station is sent is received, which includes
Random access resource information for wave beam reciprocity UE and the random access resource information for non-wave beam reciprocity UE;
Step 202, according to local terminal wave beam reciprocity implementations and the random access resource configuration information, selection accordingly with
Machine access-in resource sends the random access request for including targeting sequencing.
Embodiment 1
Referring to Fig. 3, illustrating present embodiment random access by taking random access scene competition-based as an example below
Configuration method cooperates with present embodiment random access request method and completes the complete procedure of random access.
Step 301, random access resource configuration information is divided into two classes by base station, and the first kind is to have wave beam mutual for the sides UE
Random access resource information when easy property, the second class are random access resource letter when not having wave beam reciprocity for the sides UE
Breath.
Random access resource is the resource for sending random access request to base station for UE.Random access resource includes random
Access running time-frequency resource, the leader sequence resources etc. of channel resource subset or random access channel.UE is random according to what can be used
Access-in resource determines the information such as the structure of random access channel resource subset, targeting sequencing structure, and then really directional base station is sent
Random access request structure.
Whether UE lateral beams reciprocity is true, can influence the structure of random access channel resource subset.
Specifically, if there is wave beam reciprocity, random access channel resource subset can only be connect at random by one for the sides UE
Enter channel composition, the random access channel resource subset structure of first kind random access resource is as shown in Figure 4.In Fig. 4, connect at random
Enter channel resource subset by CP (Cyclic prefix, cyclic prefix), targeting sequencing and GT (Guard Time, guard time)
Composition.UE detects the synchronizing signal of base station when carrying out down-going synchronous by way of beam scanning reception, and determines that UE is optimal
Beam direction is received, determines that the optimal transmission beam directions of UE, Fig. 5 give UE and determine optimal send wave further according to wave beam reciprocity
The example of Shu Fangxiang processes.Therefore, the UE with wave beam reciprocity is sending random access using first kind random access resource
When request, in random access channel resource subset using optimal the transmissions beam direction transmissions of UE determining by the above process with
Machine access request signal.
If the sides UE do not have wave beam reciprocity, random access channel resource subset is needed by multiple random access channel groups
At a kind of possible random access channel resource subset structure of the second class random access resource is as shown in Figure 6.In Fig. 6, one
Random access channel resource subset is made of N number of random access channel, and preceding N-1 random access channel is by CP, targeting sequencing structure
At the last one random access channel is made of CP, targeting sequencing and GT.Since UE does not have wave beam reciprocity, cannot pass through
Detection synchronizing signal determines the optimal transmission beam directions of UE, therefore, does not have the UE of wave beam reciprocity random using the second class
When access-in resource sends random access request, difference is used in multiple random access channel of random access channel resource subset
Transmission beam direction send random access request signal, each random access channel transmits identical or different targeting sequencing.This
Sample, base station side can be by determining the optimal transmission beam directions of UE to the detection of random access request, and passes through random access
Response (Random Access Response, RAR) feeds back to UE.
Step 302, base station (has wave beam reciprocity or does not have wave beam reciprocity) according to itself wave beam reciprocity implementations,
Determine first kind random access resource information and the second class random access resource information.
Whether base station lateral beam reciprocity is true, can influence the structure of targeting sequencing.Therefore base station is needed according to base station side
With the wave beam reciprocity implementations of the sides UE, reasonable disposition random access channel resource subset structure and targeting sequencing structure, determine with
Machine access-in resource configuration information.
Specifically, if base station side does not have wave beam reciprocity, base station needs to receive in a manner of beam scanning to connect at random
Enter request signal to determine the optimal reception beam direction in base station, targeting sequencing needs are repeated as many times at this time, a kind of possible random
It accesses channel resource subset or random access channel structure is as shown in Figure 7.In Fig. 7, random access channel resource subset or random
Access channel is made of CP, targeting sequencing and GT (GT can be omitted), and targeting sequencing is in each random access channel resource subset
Or be repeated as many times in random access channel, targeting sequencing number of repetition needs the beam direction range scanned related with base station side.
UE sends the targeting sequencing subsequence of multiple repetitions in a random access channel resource subset or random access channel, in this way
Base station can obtain the optimal reception beam direction in base station by the random access request that Scanning Detction UE is sent.
Base station without wave beam reciprocity can know the optimal transmission beam direction in base station by way of UE measurements.UE
The downlink synchronous signal for measuring base station obtains the optimal transmission beam direction in base station, and base station is notified in a manner of implicitly notifying.One
The possible mode of kind is targeting sequencing to be divided into mutually disjoint multiple groups, the targeting sequencing in each group represents a base station
Send beam direction.After UE determines the optimal transmission beam direction in base station by down-going synchronous process, UE selects the direction pair
The targeting sequencing group answered therefrom selects a targeting sequencing for sending random access request with equiprobability.Alternatively possible
Mode is that different transmission beam directions is distinguished by running time-frequency resource.For example, reserving multiple mutually orthogonal random access channel
Subset of resources running time-frequency resource position, each random access channel resource subset running time-frequency resource position correspond to a transmission wave beam side
To.After UE determines the optimal transmission beam direction in base station by down-going synchronous process, the corresponding random access letter of the direction is selected
Road subset of resources running time-frequency resource position is for sending random access request.Distinguish send beam direction can in a manner of the time-division,
It can also be in a manner of frequency division, for example, the different time-domain position for sending the corresponding running time-frequency resource of wave beam is identical, but on frequency domain
It is orthogonal;Or the frequency domain position of the corresponding running time-frequency resource of difference transmission wave beam is identical, but time-domain position is different.
If base station side has wave beam reciprocity, base station only needs to know the optimal transmission beam direction in base station, can lead to
It crosses wave beam reciprocity and knows the optimal reception beam direction in base station.And base station can specify that downlink synchronous signal and random access channel
Correspondence between subset of resources knows the optimal transmission beam direction in base station by UE by detecting synchronizing signal, then by random
Access request sends the optimal transmission beam direction in base station to base station.Therefore base station need not be received in a manner of beam scanning with
Machine access request signal determines the optimal reception beam direction in base station, and the targeting sequencing for random access need not be to repeat
Mode is sent.
Base station is explained in detail below and determines first kind random access resource information and the second class according to itself wave beam reciprocity implementations
The process of random access resource information.Referring to Fig. 8, in the present embodiment, base station is according to random access channel resource subset time-frequency
The time-domain position of resource distinguishes two class random access resources.In other embodiments, base station can also believe according to random access
The frequency domain position of road subset of resources running time-frequency resource distinguishes two class random access resources, and process is similar with the process of the present embodiment,
It does not repeat.
In Fig. 8, the running time-frequency resource of first kind random access channel resource subset and the second class random access channel resource
The running time-frequency resource of collection is distributed in different time slots or different time slot groups, and two class random access channel resource subsets are in the time domain
Continuously distributed, in other examples, each random access channel resource subset can also discrete distribution in the time domain.For first
The running time-frequency resource of class random access resource, random access channel resource subset includes several random access channel resource subset institutes
The running time-frequency resource position (each random access channel resource subset is made of a random access channel) of occupancy or several
(a random access channel resource subset is by multiple random access channel structures for the occupied running time-frequency resource position of random access channel
At).For the second class random access resource, the running time-frequency resource of random access channel resource subset includes multiple random access channel
Subset of resources (a random access channel resource subset is made of multiple random access channel) occupied running time-frequency resource position.
First kind random access resource includes multiple random access channel resource subsets (each random access channel resource
Collection be made of a random access channel) or multiple random access channel (a random access channel resource subset by it is multiple with
Machine accesses channel and constitutes), each random access channel resource subset corresponds to a base station and sends beam direction, and base is determined for UE
Stand after optimal transmission beam direction, random access request sent on corresponding running time-frequency resource position, with implicitly by base station most
Excellent transmission wave beam directional information passes to base station.First kind random access resource further includes UE institutes in each random access channel
The targeting sequencing number of repetition N of transmission.Second class random access resource include multiple random access channel resource subsets (one with
Machine access channel resource subset is made of multiple random access channel), random access channel resource subset random connecing of being included
Enter channel number M, UE targeting sequencing number of repetition N transmitted in each random access channel.When base station has wave beam mutual
When easy property, N=1;When base station does not have wave beam reciprocity, the number that base station receives wave beam according to base station side determines that N, N are big
In 1 integer.
Step 303, base station by several synchronizing signal blocks of down-going synchronous (Synchronize Signal Block,
SS Block) to UE send random access resource configuration information, wherein different synchronizing signal blocks use different transmission wave beams
Direction is sent.
Referring to Fig. 9, each synchronizing signal block carries first kind random access resource information and the second class random access
Resource information.Therefore the information of each synchronizing signal block carrying includes:First kind random access running time-frequency resource position, the second class with
Random access channel number M, UE that machine access running time-frequency resource position, random access channel resource subset are included is each random
Access targeting sequencing number of repetition N transmitted on channel.I.e. each synchronizing signal block both corresponds to a first kind and connects at random
Enter channel resource subset (or random access channel) and a second class random access channel resource subset.
Step 304, UE receives random access resource configuration information by several synchronizing signal blocks of down-going synchronous.
After UE completes the down-going synchronous being initially accessed, random access resource configuration information is obtained by synchronizing signal block.
Step 305, UE selects the first kind random according to random access resource configuration information and itself wave beam reciprocity implementations
Access-in resource or the second class random access resource generate random access request and send random access request signal to base station.
If UE has wave beam reciprocity, first kind random access resource is selected;If UE does not have wave beam reciprocity, select
Select the second class random access resource.UE selects random access resource to determine random access channel resource subset structure, leading sequence
Array structure etc., and the targeting sequencing sent with equiprobability selection in leader sequence resources pond, generate random access request signal
It is sent to base station.
Step 306, random access request signal is detected in base station on two class random access running time-frequency resources, and to UE feedbacks with
Machine access response.
If base station detects the targeting sequencing of UE, random access response is sent in corresponding down time-frequency resource.Such as
Fruit base station detects targeting sequencing on first kind random access running time-frequency resource, then random access response is leading comprising detecting
Sequence, the corresponding RA-RNTI of random access channel resource subset detected, it is provided by the UE time-frequencies that uplink distributes next time
Source, according to TA (Timing Advance, timing advance), the cell distributed determined by the time delay estimation between base station and UE without
The information such as line Network Temporary Identifier (Cell-Radio Network Temporary Identifier, C-RNTI).If base station
Targeting sequencing is detected on the second class random access running time-frequency resource, then in addition to that information, random access response also includes
The optimal transmission beam informations of UE, the information can receive the index of the strongest random access channel of energy come hidden by targeting sequencing
Formula notifies.I.e. for the targeting sequencing detected on the second class random access running time-frequency resource, should also contain in random access response
The index information of the optimal ID or random access channel for sending wave beam of UE.
Step 307, UE receiving random access responses, and send Msg3 (message three).
After UE leads sequence before sending, random access response is detected in random access response window.It is connect at random if detecting
Enter the targeting sequencing in response, the RA-RNTI targeting sequencing, the random access running time-frequency resource that are sent with oneself match, then judge
To receive correct random access response, and send Msg3.If UE is sent at random on the second class random access running time-frequency resource
Access request then sends beam direction according to the optimal transmission beam information adjustment of the UE in random access response, sends Msg3.
The information such as the user terminal identification comprising UE and RRC connection request in Msg3.
Step 308, base station receives Msg3, and sends Conflict solving mark to UE, completes random access procedure.
Base station sends Conflict solving mark to UE, wherein the user terminal identification of the UE to win included in Conflict solving.
UE upgrades to C-RNTI after the mark for detecting oneself, by interim C-RNTI, sends ack signal to base station, completion connects at random
Enter process, and waits for the scheduling of base station.Otherwise, UE starts new random access procedure after being delayed at one section.
Embodiment 1 details mistake of the accidental access method applied to random access competition-based of present embodiment
The accidental access method of journey, present embodiment is also applied for based on non-competing random access procedure.
Under based on non-competing random access scene, base station reserve a part of targeting sequencing for based on it is non-competing with
Machine access procedure.For needing to initiate the UE of non-competing random access, base station is random for its configuration from reserved targeting sequencing
Access lead sequence.If base station can know UE lateral beam reciprocity implementations, according to UE lateral beam reciprocity implementations distribution the
A kind of random access resource or the second class random access resource.If base station can not know UE lateral beam reciprocity implementations, together
When distribution first kind random access resource and the second class random access resource.Base station is by the targeting sequencing of configuration and other connects at random
Enter resource allocation information and UE is notified by down control channel, DSCH Downlink Shared Channel or system information.
UE selects corresponding random access resource according to random access resource configuration information and itself wave beam reciprocity implementations
(when base station can not know UE wave beam reciprocity implementations), or directly according to the specified random access resource in base station, targeting sequencing
(when base station can know UE wave beam reciprocity implementations) generates random access request signal and sends.
After base station detects targeting sequencing, random access response is sent in DSCH Downlink Shared Channel.UE is received to be connect at random
Random access procedure is completed after entering response.
Embodiment 2
In scheme described in embodiment 1, base station is provided in a manner of the time-division according to random access channel resource subset time-frequency
The time-domain position in source distinguishes two class random access resources, and the present embodiment will describe a kind of base station and distinguish two classes using the mode that code is divided to
The random access scheme of random access resource, wherein part same as Example 1 does not repeat in the present embodiment.
Step 401, random access resource configuration information is divided into two classes by base station, and the first kind is to have wave beam mutual for the sides UE
Random access resource information when easy property, the second class are random access resource letter when not having wave beam reciprocity for the sides UE
Breath.
Available targeting sequencing is divided into two classes by base station, and first kind targeting sequencing, which is allocated to the UE with wave beam reciprocity, to be made
With the second class targeting sequencing is allocated to the uses of the UE without wave beam reciprocity.Two class targeting sequencings mutually disjoint.Base station can be with
According in the UE of present access network, the UE ratios with reciprocity and without reciprocity adjust the number of two class targeting sequencings
Amount.
For the running time-frequency resource of random access channel resource subset, no longer it is distinguish for two in the scheme of the present embodiment
The different UE of class wave beam reciprocity implementations is used.The random access channel resource subset running time-frequency resource of the present embodiment time domain (
In other embodiments or frequency domain) on be repeated cyclically distribution, the UE with reciprocity and UE without reciprocity are total to
Identical random access channel resource subset running time-frequency resource is enjoyed, the interference for avoiding to occur by using different targeting sequencings
And conflict.
Two kinds of arrangements that random access channel resource subset running time-frequency resource is repeated cyclically distribution in the time domain are given below
Mode.(1) each random access channel resource subset continuous or discrete distribution in the time domain, and each independently in the time domain
It is repeated cyclically.(2) the continuously distributed formation random access channel resource of multiple random access channel resource subsets, and with the shape of group
Formula is repeated cyclically distribution in the time domain.For example, occurring one every k time slot in time domain there is identical random access channel to provide
The random access channel resource of source subset number.
Step 402, base station (has wave beam reciprocity or does not have wave beam reciprocity) according to itself wave beam reciprocity implementations,
Determine first kind random access resource information and the second class random access resource information.
First kind random access resource includes the range of first kind targeting sequencing index, UE provides in each random access channel
Transmitted targeting sequencing number of repetition N in the subset of source.For random access channel resource subset running time-frequency resource described in step 401
Arrangement mode (1), the second class random access resource includes the range of the second class targeting sequencing index, maximum workable for UE with
Machine accesses the targeting sequencing repetition time transmitted in each random access channel resource subset of channel resource subset number I, UE

Step 405, UE selects the first kind random according to random access resource configuration information and itself wave beam reciprocity implementations
Access-in resource or the second class random access resource generate random access request and send random access request signal to base station.
If UE has wave beam reciprocity, targeting sequencing is selected in first kind targeting sequencing index with equiprobability, is used
Random access channel resource subset of the selected targeting sequencing indicated by synchronizing signal block is (for random described in step 401
Access the arrangement mode (1) of channel resource subset running time-frequency resource), or it is (right in the random access channel resource periodically occurred
The arrangement mode (2) of the random access channel resource subset running time-frequency resource described in step 401) in a random access channel money
In the subset of source, random access request signal is sent.
If UE does not have wave beam reciprocity, targeting sequencing is selected in the second class targeting sequencing index with equiprobability, is made

Random access request signal is sent in I existing random access channel resource subset (for random access channel described in step 401
The arrangement mode (1) of subset of resources running time-frequency resource);Or the random access channel resource indicated by synchronizing signal block is (random
Access channel resource is made of J random access channel resource subset) on, random access request signal is sent (for step 401
The arrangement mode (2) of the random access channel resource subset running time-frequency resource).
Step 406, random access channel resource subset or random of the base station indicated by random access resource configuration information
Random access request signal is detected on access channel resource, and feeds back random access response to UE.
If base station detects the targeting sequencing of UE, random access response is sent in corresponding down time-frequency resource.Such as
Fruit base station is first kind targeting sequencing what is detected, then random access response includes the targeting sequencing detected, detects
The corresponding RA-RNTI of random access channel resource subset, by the UE running time-frequency resources that uplink distributes next time, according to base station with
The information such as TA determined by the time delay estimation between UE, the Cell Radio Network Temporary Identifier/Identity, Cell-RNTI distributed.What if base station detected
It is the second class targeting sequencing, then in addition to that information, random access response also includes the optimal transmission beam informations of UE, the information
The index of the strongest random access channel of energy can be received by targeting sequencing implicitly to notify.I.e. for detecting the second class
The case where targeting sequencing, should also contain the rope of the optimal ID or random access channel for sending wave beam of UE in random access response
Fuse ceases.
