Specific implementation mode

Exemplary embodiment of the present invention is more fully described below with reference to accompanying drawings.Although showing the present invention in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the present invention without should be by embodiments set forth here It is limited.It is to be able to be best understood from the present invention on the contrary, providing these embodiments, and can be by the scope of the present invention Completely it is communicated to those skilled in the art.

As shown in Figure 1, the system information transmission method of the embodiment of the present invention, is applied to base station side, specifically includes following step Suddenly：

Step 11：The minimum system information for carrying default correspondence relationship information is sent to terminal.

Wherein, default correspondence is：Allow by between the MSG1 other systems information asked and random access resource Correspondence.Further, other systems information is：Whole system informations in addition to minimum system information, allow to pass through MSG1 request other systems information be：Whole system informations in the default set of other systems information or other systems At least one of information system information.

Specifically, step 11 is：Base station carries default correspondence relationship information most by broadcast mode, to terminal transmission Mini system information.For being in the terminal UE of Idle state/inactive state (idle/inactive), base station can be by minimum Information configuration of uniting, which passes through MSG1, asks other systems information other SI, wherein other SI be except minimum system information MSI it Outer other systems information.And the other SI made requests on by MSG1 is allowed to specifically include：The default set of other SI In whole system informations, alternatively, at least one of other SI system informations.

That is the certain fixed other SI set of base station configuration can be made requests on by MSG1, and base station is by these other SI Correspondence configuration between corresponding random access resource is sent to terminal in minimum system information.Alternatively, base station is unworthy of Fixed other SI set is set, but selects at least one system information to allow to be asked by MSG1 from other SI It asks, the correspondence between these other SI and corresponding random access resource is configured and sent in minimum system information by base station To terminal.

Step 12：Receive one MSG1 of random accessing message that terminal is sent according to minimum system information.

Wherein, MSG1 is for asking other systems information.Which terminal can know after receiving minimum system information The other SI that other SI can be made requests on by MSG1, and be not recorded in minimum system information can be carried out by MSG3 Request.When terminal needs the other SI asked there are corresponding default correspondence, then can pass through in minimum system information MSG1 carries out the request of other systems information.

Further, the default correspondence configured in minimum system information specifically includes following correspondence：

Mode one, default correspondence are：In the other systems information for allowing to ask by MSG1, each system information With the one-to-one relationship of random access resource.This mode refers to each other SI for allowing to make requests on by MSG1 Corresponded with random access resource PARCH resource.Assuming that other SI can be divided into multiple system resource blocks (other SI Block, OSIB), OSIB1, OSIB2... etc., it is assumed that OSIB3, OSIB4, OSIB5 can be asked by MSG1 It asks, then 3 PRACH resource is at least needed to be corresponded with OSIB3, OSIB4 and OSIB5.When UE needs OSIB3 simultaneously When with OSIB4, then the corresponding PRACH resource of the OSIB3 can be used to carry out MSG1 requests respectively, it is corresponding using OSIB4 PRACH resource carry out MSG1 requests, can reduce the expense of PRACH resource to a certain extent in this way.

Mode two, default correspondence are：In the other systems information for allowing to ask by MSG1, there is identical function System information relationship corresponding with same random access resource.This mode refers to other SI functions and PRACH Resource is corresponded, corresponding with RPRACH resource by the corresponding all OSIB of each function.Such as cell reselection work( OSIB3, OSIB4 and OSIB5 can be corresponded to, then OSIB3, OSIB4 and OSIB5 correspond to identical PRACH resource.Its In, the corresponding random access resources of other SI of identical function are identical, the corresponding random access of other SI of different function Resource is different.

Mode three, default correspondence are：In the other systems information for allowing to ask by MSG1, each system information And whole combinations of different system information are one-to-one relationship with random access resource.This mode refers to not only Each other SI and PRACH resource are corresponded, whole combinations of multiple and different other SI also with PRACH Resource is corresponded.Such as OSIB3 and OSIB4 can be asked by MSG1, then there are 3 groups of correspondences, wherein 1 PRACH resource are corresponding with OSIB3, and a PRACH resource is corresponding with OSIB4, PRACH resource with The combination of OSIB3 and OSIB4 is corresponding.Due to being not only configured with single other SI and PRACH in minimum system information The correspondence of resource, is also configured with the correspondence of multiple other SI combinations and PRACH resource, therefore works as When terminal has multiple other SI requests demands, terminal can once ask multiple other by corresponding PRACH resource SI can reduce the interaction flow between terminal and base station, shorten the stand-by period.It is worth noting that when there is the n other SI can When being made requests on by MSG1,2 are configured in minimum system informationⁿ- 1 group presets correspondence.

Mode four, default correspondence are：In the other systems information for allowing to ask by MSG1, each system information And the part combination of different system information is one-to-one relationship with random access resource.Although this mode refers to Each other SI and PRACH resource are corresponded, but be not multiple and different other SI whole combinations with PRACH resource are corresponded, wherein only part combination is corresponding with PRACH resource.Such as OSIB3, OSIB4 and OSIB5 can be asked by MSG1, then at least there are 3 groups of correspondences, wherein 1 PRACH resource with OSIB3 is corresponding, and 1 PRACH resource is corresponding with OSIB4, and 1 PRACH resource is corresponding with OSIB5.And One PRACH can be configured by base station flexible configuration, such as base station for the combination of multiple and different other SI Resource is used for OSIB3 and OSIB4, and the PRACH resource are then used when UE needs OSIB3 and OSIB4 simultaneously.

From the foregoing, it will be observed that as shown in Fig. 2, the step of carrying the minimum system information of default correspondence to terminal transmission Before, system information transmission method of the invention further includes：

Step 21：Configuration allows the other systems information asked by MSG1.

Specifically, step 21 may include：Whole system informations in the default set of other systems information are configured to permit Perhaps the other systems information asked by MSG1.It refers here to, the other SI that base station fixed configurations can be asked by MSG1, It will be divided into default set by the MSG1 all other SI asked, such as OSIB3, OSIB4 and OSIB5 can pass through MSG1 makes requests on, then base station is by OSIB3, OSIB4 and OSIB5, all configuration is in minimum in minimum system information OSIB3, OSIB4 and OSIB5 can only be configured in system information to ask by MSG1.

Alternatively, step 21 may also include：By at least one of system information some or all of in other systems information System information is configured to the other systems information for allowing to ask by MSG1.It refers here to, base station flexibly configurable allows to lead to Cross the other SI of MSG1 requests, it is assumed that all other SI can be made requests on by MSG1, but base station visually actually needs The other SI of preset quantity are selected to configure in minimum system information, such as all OSIB can be asked by MSG1 It asks, base station is actually asked by minimum system message arrangement OSIB3 and OSIB4 by MSG1.Or part other SI can It is made requests on by MSG1, such as the default set in aforesaid way, base station is not all by whole other in default set SI is configured in minimum system information, but optionally the other SI of selection preset quantity are configured in minimum system information. Such as：OSIB3, OSIB4 and OSIB5 are default set, and can be made requests on by MSG1, but base station actually can be by most Mini system message arrangement OSIB3 and OSIB4 are asked by MSG1.

Step 22：Configure the first random access resource of MSG1.

Wherein, random access resource includes：Random access sequence (PRACH preamble) and/or random access time-frequency money Source (PRACH time/frequency resource).

Specifically, step 22 includes：Will in random access resource preset set in some or all of resource distribution be The first random access resource of MSG1.This mode refers to the random access resource pre-defined for other SI requests Default set, base station selection resource can only carry out the request of other SI from the default set.

Further, will in random access resource preset set in some or all of resource distribution be MSG1 first After the step of random access resource, further include：When terminal carries out random access, by collecting except default in random access resource The resource except random access resource in conjunction receives the access request that terminal is sent.

That is, having pre-defined the PRACH resource set for other SI requests, base station can only be from calmly PRACH resource are chosen in the PRACH resource set of justice for other SI requests, when UE carries out random access not PRACH resource can be chosen from the PRACH resource set be used for random access.

Alternatively, step 22 may also include：Selected section resource distribution is the first of MSG1 from all random access resources Random access resource.This mode refers to that all random access resources for random access are used equally for other SI to ask It asks, base station can select any cost to carry out other SI requests from random access resource.

Further, it is provided in the first random access that selected section resource distribution is MSG1 from all random access resources After the step of source, further include：When terminal carries out random access, by removing the first random access resource in random access resource Except resource, receive terminal send access request.

That is, all PRACH resource for random access can be used for other SI requests, base station Resource is chosen from all PRACH resource and carries out other SI requests, and is configured in minimum system message.UE exists When carrying out random access, minimum cannot be chosen by needing first to detect PRACH resource, UE configured in minimum system information The configured PRACH resource of system information carry out random access.

Step 23：According to allowing by the MSG1 other systems information asked and corresponding first random access resource, really Surely allow through the default correspondence between the MSG1 other systems information asked and random access resource.

Wherein it is determined that default correspondence meet above 4 in corresponded manner, therefore details are not described herein.

Step 24：Correspondence is preset according to this, configures minimum system information.

After determination allows the correspondence of the other SI and PRACH resource asked by MSG1, by the correspondence Relationship configuration notifies terminal in minimum system information.

Step 25：The minimum system information for carrying default correspondence is sent to terminal.

Specifically the minimum system information for carrying default correspondence is sent to terminal by him by broadcast mode.

Step 26：Receive one MSG1 of random accessing message that terminal is sent according to minimum system information.

Terminal can know which other SI can be made requests on by MSG1 after receiving minimum system information, and The other SI being not recorded in minimum system information can be made requests on by MSG3.When terminal needs the other SI asked to exist There are corresponding default correspondences in minimum system information, then the request of other systems information can be carried out by MSG1.

The system information transmission method of the embodiment of the present invention, base station would allow through MSG1 and asked by minimum system information Correspondence between the other systems information asked and random access resource is sent to terminal, when terminal need ask other be When system information belongs to the system information in the correspondence, terminal is sent by the random access resource in correspondence to base station MSG1 is to ask corresponding other systems information, to solve the request allocation problem of other systems information, realize terminal-pair other The request of system information.
