Specific embodiment

The present invention is further described in more detail with reference to the accompanying drawings and embodiments.

System information is sent with the mode of beam scanning, needs to repeat on multiple wave beams to send identical system information, Compared with being based on simple beam in existing LTE system and sending resource required for system information, it is scanned on N number of wave beam, Just need to consume the resource of the N times of prior art.On the other hand, system information now in a communications system is periodicity sending , system transmission resources consumed by scanning beam can greatly increase overhead.On-demand system information transmission is a kind of drop The method of low overhead only sends system information when terminal has demand.

In the communication system based on multi-beam transmission, base station can be sent by way of sweeping wave beam synchronization signal and (host system message block (MIB, Master Information Block) in similar LTE is for some most basic system informations It unites block of information 1 (SIB1), most basic system information in system information block 2 (SIB2)).For this process, as shown in Figure 1, Terminal can receive these information (steps 101) on multiple beam directions first, the other systems information outside these information not into Row sweeps wave beam transmission, only when terminal needs to obtain further other system informations, carries out system information request (SIR, SI Request after) reporting (step 102), base station to receive SIR, follow-up system information can be further sent based on SIR, is pressed with realizing It needs to send (103).

From the above description, it will be seen that realizing and sending on demand in order in the communication system based on multi-beam transmission System information, terminal need SI reporting R.So, the stage is obtained in system information, since terminal does not access network, so It can not carry out terminal and specifically request to report (specify/to determine terminal using specific running time-frequency resource/code word progress by scheduling Report), the side of similar physical random access channel (PRACH, Physical Random Access CHannel) can only be used Formula transmission, since each user needs fixed resource, and cannot at least two users use identical resource, though so in this way It so is able to achieve reporting for SIR, but will also result in and report resource overhead larger.

What is provided in Fig. 1 diagram realizes that the process for sending system information on demand is shown by way of sweeping wave beam in the related technology It is intended to.When practical application, when realizing the process of random access by way of sweeping wave beam, similarly exists and report resource overhead Big problem.

Therefore how terminal reports solicited message under the premise of economizing on resources, and being reported in which kind of resource all is to need It solves the problems, such as.

Based on this, in various embodiments of the present invention: terminal receives that base station is sent in a manner of based on multi-beam One information；The first information includes the first system information and/or synchronizing information；The base station is obtained in the side based on multi-beam The second information when formula is sent；Optimal launching beam letter of second information representation when the mode based on multi-beam is sent Breath；Using second information, determining report reports resource needed for solicited message in reserved resource；It is reported using determining Resource reports the solicited message to base station；The solicited message is for requesting the base station to send corresponding third information；And Base station receives the solicited message that terminal reports；And it is obtained in receive process and reports the solicited message is occupied to report money Source；The solicited message is occupied to report resource according to reporting, and determines the second information；Second information representation is based on more Optimal launching beam information when the mode of wave beam is sent；According to second information, determine that sending the solicited message corresponds to Third information needed for transmission resource；It is corresponding with the solicited message to terminal transmission using determining transmission resource Third information.

Embodiment one

The present embodiment provides a kind of information transferring methods, are applied to terminal, as shown in Fig. 2, method includes the following steps:

Step 201: receiving the first information that base station is sent in a manner of based on multi-beam；

Here, the mode based on multi-beam can be beam scanning.

The first information may include the first system information and/or synchronizing information.

Wherein, the first system information is properly termed as fundamental system information, may include: system bandwidth, random access configuration Measurement, handover configurations Deng the terminal needs of the most basic system information and/or connected state of the terminal needs in Idle state Deng.

The synchronizing information is to need received information at first before terminal access system, obtains timing for terminal, It is also first received than fundamental system information, without synchronizing information, terminal can not receive fundamental system information.

Step 202: obtaining second information of the base station when the mode based on multi-beam is sent；

Here, optimal launching beam information of second information representation when the mode based on multi-beam is sent.

When practical application, second information includes that following information is at least one:

Wave beam ID；

As shown in Figure 1, when step 101 is completed, available second information of terminal.

Wherein, when synchronizing signal/fundamental system information transmission based on the mode of multi-beam due to base station, these signals The position of transmission is fixed.

Based on this, the first is achieved in that terminal obtains the ID of optimal launching beam, specifically includes:

In other words, as shown in Fig. 3 a and 3c, terminal carries out trial reception on multiple wave beams, correctly demodulates signal Afterwards, each beam information, i.e. wave beam ID can be obtained in terminal.By comparing the received signal quality of each wave beam, terminal can be with Judge the wave beam ID of optimal launching beam, such as optimal launching beam ID is wave beam 3.

It is achieved in that for second when terminal obtains the corresponding first information transmission of optimal launching beam and transmits at least twice Between the first sequential relationship, specifically include:

As shown in Figure 3b, terminal is attempted to receive signal in multiple time-domain resources, and after correctly demodulating signal, terminal compares Received signal quality in these time-domain resources, terminal can judge the reception timing for preferably receiving signal, such as second A synchronizing sequence timing/fundamental system information timing.

The third is achieved in that terminal obtains the corresponding sequential relationship of optimal launching beam and frequency resource, specific to wrap It includes:

As shown in Figure 3d, trial receives signal to terminal respectively when multiple, in frequency domain resource, after correctly demodulating signal, Received signal quality when terminal compares these, in frequency resource, terminal can judge the reception timing for preferably receiving signal And the first segment frequency location on frequency location, such as second synchronizing sequence timing/fundamental system information timing.

Wherein, when practical application, the received signal quality specifically can by received signal strength or signal-to-noise ratio etc. come It embodies.

Step 203: utilizing second information, determining report reports resource needed for solicited message in reserved resource；

After terminal obtains optimal launching beam information, i.e., it is believed that being rung in subsequent on-demand system information and/or random access In the transmission process answered, it is expected that being received on this optimal launching beam.Therefore terminal needs to carry out this information Report, enables base station to obtain following two information:

1, terminal is just in solicited message；

2., terminal reported optimal launching beam information, i.e., in a certain optimal launching beam ID and/or specific time sequence relationship And/or on-demand system information and/or random access response are received in specific frequency resources.

In addition, due to the also non-access communications system of terminal, base station can not dispatch terminal transmitted in specific resources.Cause , in order to report above- mentioned information, terminal can be reported in resource reserved in advance for this.

Based on this, specifically, according to optimal launching beam ID in second information, from the reserved resource selection with The corresponding resource block of the ID reports resource described in being used as；Wherein,

That is, reporting resource corresponding with wave beam ID.For example for, as shown in fig. 4 a, terminal has determined that optimal Beam information is wave beam 3.So a kind of situation, which is that wave beam 3 is corresponding, reports position is identical as transmitting position (to report timing and hair Send the sequential relationship of the first information consistent), i.e. second resource block from left to right in Fig. 4 a.Alternatively possible is such as Fig. 4 b institute Show, wave beam 3 is corresponding to report position to be determined by its own serial number, as third timing resource block (reports from left to right in Fig. 4 b Timing and the sequential relationship for sending the first information are inconsistent, but reporting timing is also to have made an appointment with base station).If transmitting Multi-beam also have differentiation (as shown in Figure 3c) in frequency domain, that terminal reports resource that can also distinguish on frequency domain, such as Terminal can with reported on identical timing and frequency domain position shown in Fig. 3 c, can also according to certain criterion, by its own Serial number determine corresponding timing and frequency domain position, but the criterion need to make an appointment.

Alternatively, terminal is according to the first sequential relationship and/or first frequency resources relationship in second information, from described Resource block corresponding with first sequential relationship and/or first frequency resources relationship is selected to report as described in reserved resource Resource.

That is, according to specific time sequence relationship (the first sequential relationship) and/or specific frequency resources relationship (first frequency Resources relationship) determination reports resource, that is, report reception synchronization signal/fundamental system information in resource and optimal beam information Timing and/or frequency relation are corresponding.For example for, as illustrated in fig. 4 c, by step 101 shown in FIG. 1, terminal is true It is optimal for determining the second timing position in synchronizing sequence timing, then terminal also selectes resource when determination reports resource location The second timing position in group is reported.For another example, as shown in figure 4d, by step 101 shown in FIG. 1, terminal is had determined that First frequency resource in synchronizing sequence timing on the second timing position is optimal, then terminal reports resource location in determination When, the first frequency resource also selected on the second timing position in resource group is reported.

Here, in Fig. 4,Expression reports the timing of resource；↑, → indicate the timing of launching beam.

Wherein, when practical application, reserved resource can be according to optimal launching beam information or the first information transmission when Between/frequency domain resource made an appointment.

The position of the reserved resource is fixed position (not generating variation with any factor, be fixed and invariable), or Described in person reserve resource position be the position determined by fundamental system information or the reserved resource be and previous step receive The timing of the first information differs the resource (as shown in Figure 5) after specific duration.

In addition, the size of the reserved resource can be fixed or the size of the reserved resource when practical application It can be configuration.

Wherein, the size of the reserved resource can be according to some essential information configurations such as system bandwidth.Such as Fig. 6 a and Shown in 6b.

Here, in Fig. 6 a, system bandwidth is smaller, can only occupy as existing LTE system shared by reserved resource 6 Physical Resource Block.When corresponding system bandwidth is larger, as shown in Figure 6 b, reserved resource can take up more physics Resource block.Above-mentioned only example, specifically reserved resource size is not limited only to above-mentioned data.

Step 204: reporting resource to report the solicited message to base station using determining.

Here, the solicited message is for requesting the base station to send corresponding third information.

Here, when practical application, the solicited message can be system information request and/or random access request；Accordingly Ground, the third information are second system information and/or random access response；The second system information and the first system Information is different.

When practical application, the second system information may include that the terminal of only connected state is required after random access System information.

More specifically, when the solicited message is system information request, the third information is second system information； When the solicited message is random access request, the third information is random access response；When solicited message is system letter When breath request and random access request, the third information is second system information random access response.

When realizing the interaction of terminal and base station, required system information includes the first system information and second system letter Breath.

When practical application, after terminal determination reports resource, suitable reference signal sequence is selected, carries out system information request It reports.

Wherein, reference signal sequence can be corresponding with second information, can such as be carried out with optimal launching beam ID Scrambling code；Or timing and/or frequency location according to optimal launching beam, the choosing in one group of given reference signal sequence combination Take the sequence of corresponding position.

So far terminal completion reports process, identical optimal due to having chosen after scheme provided in an embodiment of the present invention Multiple terminals of launching beam will use identical resource and be reported, as long as therefore not having on a certain wave beam/timing/frequency location There is system information request to report, this part reports resource to can be saved.

After base station receives the solicited message, the corresponding wave beam of the second information for reporting resource to indicate will use, send institute State third information.

Based on this, in one embodiment, this method can also include:

Here, when practical application, corresponding with second information wave beam sends transmission resource when third information, can be with Resource consistence is sent used in the wave beam when sending with the first information, that is, uses identical reference symbol.

The embodiment of the invention also provides a kind of information transferring methods, are applied to base station, as shown in fig. 7, this method comprises:

Step 700: the first information is sent in a manner of based on multi-beam；The first information includes the first system information And/or synchronizing information；

Here, the mode based on multi-beam can be beam scanning.

Step 701: receiving the solicited message that terminal reports；

It is described that report request can be system information request and/or random access request.

Step 702: being obtained in receive process and report the solicited message is occupied to report resource；

Specifically, signal is received by way of based on multi-beam on reserved ascending resource；

In other words, base station can be scanned on reserved ascending resource to receive signal, if correctly certain for the moment, Demodulate signal in frequency resource, though do not demodulate signal for the moment, in frequency resource at certain, detect and connect in the resource Receive signal quality it is fine, it is believed that being corresponding with solicited message on this timing/running time-frequency resource, and can be by this when Sequence/running time-frequency resource gets the optimal launching beam information that terminal reports.

Wherein, the optimal launching beam information includes that following information is at least one:

Optimal launching beam ID；

And then the resource that reports that available base station determines is the corresponding resource block of at least one of information:

When sending the first information with the mode based on multi-beam between transmission at least twice optimal launching beam first when Order relation；

First frequency of optimal launching beam between being transmitted at least twice when sending the first information with the mode based on multi-beam Rate resources relationship.

Step 703: the solicited message is occupied to report resource according to reporting, and determines the second information；According to described Two information determine transmission resource needed for sending the corresponding third information of the solicited message；

When practical application, transmission resource when third information, Ke Yiyu are sent according to the wave beam that second information determines Resource consistence is sent when the first information is sent used in the wave beam, that is, uses identical reference symbol.

After the completion of this step, base station obtains two required information:

1, terminal is just in solicited message；

2, the optimal launching beam information that terminal reports, i.e. terminal are wished in a certain optimal launching beam ID and/or specific On-demand system information is received in sequential relationship and/or specific frequency resources and/or is then responded at random.

704: sending third information corresponding with the solicited message to the terminal using determining transmission resource.

Wherein, correspondingly, the third information can be second system information and/or random access response；Described second System information is different from the first system information.

The solicited message can be system information request and/or random access request；Correspondingly, the third information is Second system information and/or random access response；The second system information is different from the first system information.

Here, when practical application, it is only necessary to carry out system information and/or random access response hair when having request It send, base station in which resource it needs to be determined that send, and terminal is needed to know and be received in which resource.Therefore, for The transmission of system information, one kind sending the achievable method of system information on demand is: it is similar with existing LTE system, it will send out on demand The time-domain position for the first systematic information sent is fixed, this time-domain position also with optimal launching beam ID and/or specific Sequential relationship and/or specific frequency resources are corresponding, and terminal only need to report the identical ID of resource and/or timing and/or frequency with it It is received in rate resource.In other resources of not system information request, these resources can be used for transmitting other Data.

It should be understood that the embodiment of the present invention is not asked to terminal transmission with described to using determining transmission resource The specific implementation process of the corresponding third information of system is asked to be defined.

From the above description, it will be seen that in the embodiment of the present invention, as long as having selected identical optimal launching beam letter Multiple terminals of breath will select identical resource to be reported to make requests information reporting.

Information transferring method provided in an embodiment of the present invention, terminal receive that base station is sent in a manner of based on multi-beam One information；The first information includes the first system information and/or synchronizing information；The base station is obtained in the side based on multi-beam The second information when formula is sent；Optimal launching beam letter of second information representation when the mode based on multi-beam is sent Breath；Using second information, determining report reports resource needed for solicited message in reserved resource；It is reported using determining Resource reports the solicited message to base station；The solicited message is for requesting the base station to send corresponding third information；And Base station receives the solicited message that terminal reports；And it is obtained in receive process and reports the solicited message is occupied to report money Source；The solicited message is occupied to report resource according to reporting, and determines the second information；Second information representation is based on more Optimal launching beam information when the mode of wave beam is sent；According to second information, determine that sending the solicited message corresponds to Third information needed for transmission resource；It is corresponding with the solicited message to terminal transmission using determining transmission resource Third information, in this way, realizing terminal using reserved resource reporting solicited message.Meanwhile it being provided using the embodiment of the present invention Scheme when, multiple terminals due to having chosen identical optimal launching beam will use identical resource and be reported, only Want there is no solicited message to report on a certain wave beam/timing/frequency location, this part reports resource to can be saved, in this way, can Resource is reported to greatly save.

Specifically, the first acquisition unit 82, is used for:

In other words, as shown in Fig. 3 a and 3c, terminal carries out trial reception on multiple wave beams, correctly demodulates signal Afterwards, each beam information, i.e. wave beam ID can be obtained in the first acquisition unit 82.By comparing the reception signal of each wave beam Quality, the first acquisition unit 82 may determine that the wave beam ID of optimal launching beam, such as optimal launching beam ID is wave Beam 3.

It is achieved in that the first acquisition unit 82 obtains the corresponding first information transmission of optimal launching beam for second When at least twice transmission between the first sequential relationship.
