In this application.

技术领域 Technical field

本发明涉及通信技术领域，尤其涉及一种***信息调度方法、装置及终端。背景技术 The present invention relates to the field of communications technologies, and in particular, to a system information scheduling method, apparatus, and terminal. Background technique

在蜂窝***中， ***信息（SI, System Information )是指某个小区或多个小区的公共信息。由于 SI的内容比较多，所以按照特性可以分成多个***信息块（SIB, System Information Block ), 每个 SIB包含同一特性的***信息。例如， SIB-1主要包含用户设备（UE, User Equipment )在空闲模式下的定时器和计数器参数信息。 In a cellular system, system information (SI, System Information) refers to public information of a certain cell or a plurality of cells. Since the content of SI is relatively large, it can be divided into a plurality of system information blocks (SIBs) according to characteristics, and each SIB contains system information of the same characteristic. For example, SIB-1 mainly includes timer and counter parameter information of the user equipment (UE, User Equipment) in idle mode.

通常在陆地无线接入网（UMTS , Universal Mobile Telecommunications System )中， ***信息的结构是树状的，如图 1所示，根节点是主消息块（ MIB, Master Information Block ) , MIB包括一个或两个调度块（ SB , Scheduling Block ) , 每个 SB中包含多个 SIB的调度相关的信息。在广播信道（BCH , Broadcast Channel )上各个 SIB都是有一个固定的周期，所以会重复出现。这些 SIB的调度信息是在 MIB中， UE从 MIB中读取到了 SIB的调度信息，例如， SIB的开始位置、 SIB的周期、 SIB的分块信息等等，这时候 UE就可以知道 SIB 会在什么地方出现，当 UE正确地接收到某个 SIB以后，就不用重复去接收，直到 SIB变更的时候才会再去接收。 Generally, in the Universal Mobile Telecommunications System (UMTS), the structure of system information is tree-like. As shown in FIG. 1, the root node is a Master Information Block (MIB), and the MIB includes one or Two scheduling blocks (SB, Scheduling Block), each of which contains scheduling related information of multiple SIBs. Each SIB on the broadcast channel (BCH, Broadcast Channel) has a fixed period, so it will repeat. The scheduling information of these SIBs is in the MIB, and the UE reads the scheduling information of the SIB from the MIB, for example, the starting position of the SIB, the period of the SIB, the block information of the SIB, etc., at this time, the UE can know that the SIB will be Where does it occur, when the UE correctly receives an SIB, it does not have to repeat the reception until the SIB changes.

在长期演进（LTE, Long Term Evolution )***中， SI的结构如图 2所示，在进行***信息调度时，把具有相同特性的 SIB集中到一起形成一个调度单元 ( SU, Scheduling Unit ), 其作用是把具有相同调度特性的 SIB放到一起，相当于一个容器， SU是目前 LTE***中***信息调度的基本单位。这里的相同特性主要是指信息重复的周期。如图 3 所示，目前在协议中确定的一共有 4 个调度单元 SU, MIB映射到 BCH上， SB在最频繁调度单元（ SU-1 , The most frequently repeated Scheduling Unit )中，且 SU-1同其它 SU映射到下行共享信道（ DL-SCH, Downlink Shared Channel )上。 MIB和 SU-1都有固定的调度周期，分别是 40ms和 80ms。 SU-1在特定的无线帧上调度，这个无线帧通过系统帧号（ SFN, System Frame Number ) SFN mod 8=0 ( SFN单位是 10ms的无线帧）计算出来。 In the Long Term Evolution (LTE) system, the structure of the SI is as shown in FIG. 2. When performing system information scheduling, SIBs having the same characteristics are grouped together to form a scheduling unit (SU, Scheduling Unit). The role is to put the SIBs with the same scheduling characteristics together, which is equivalent to a container. SU is the basic unit of system information scheduling in the current LTE system. The same characteristics here mainly refer to the cycle of information repetition. As shown in Figure 3, there are currently 4 scheduling units SU determined in the protocol, the MIB is mapped to the BCH, and the SB is in the most frequently scheduled Scheduling Unit (SU-1), and the SU-1 The other SUs are mapped to the downlink shared channel (DL-SCH, Downlink Shared Channel). Both MIB and SU-1 have fixed scheduling weeks Periods are 40ms and 80ms respectively. SU-1 is scheduled on a specific radio frame, which is calculated by the system frame number (SFN, System Frame Number) SFN mod 8 = 0 (the SFN unit is a radio frame of 10 ms).

发明人经过研究发现，在现有技术进行 SU的调度方案中，如果 SU-1在多个连续或者非连续的子帧上发送，则 UE不能正确的接收 SU-1。 The inventors have found through research that in the prior art scheduling scheme of SU, if SU-1 is transmitted on multiple consecutive or non-contiguous subframes, the UE cannot correctly receive SU-1.

发明内容 Summary of the invention

具体实施方式 detailed description

下面结合附图和具体实施方式对本发明作进一步描述。 The invention is further described below in conjunction with the drawings and specific embodiments.

本发明实施例提供一种***信息调度方法、装置及终端，能够使得 UE正确的接收到 SU-1 , 进而能正确、有效地接收到完整的***信息。为使本发明的目的、技术方案及优点更加清楚明白，下面参照附图并举实施例，对本发明进一步详细说明。 The embodiment of the invention provides a system information scheduling method, device and terminal, which enable the UE to correctly receive the SU-1, and thus can receive the complete system information correctly and effectively. In order to make the objects, the technical solutions and the advantages of the present invention more comprehensible, the present invention will be described in detail below with reference to the accompanying drawings.

如图 4所示，为本发明实施例一提供的***信息调度方法的流程图，包括以下步骤： As shown in FIG. 4, it is a flowchart of a system information scheduling method according to Embodiment 1 of the present invention, which includes the following steps:

步骤 401 :终端获取 SU-1的调度信息，根据所述调度信息接收完整的 SU-1 的信息； Step 401: The terminal acquires scheduling information of SU-1, and receives complete SU-1 information according to the scheduling information.

步骤 402: 终端获取动态调度的窗口信息，根据所述窗口信息接收其它调度单元 SU-n的信息， η>1 ; 步骤 403: 终端从所述 SU-1 的信息中获取***信息块 SIB和所述 SU-n 的映射信息，根据所述映射信息指示的 SIB和所述 SU-n之间的对应关系，获取所有的***信息。 Step 402: The terminal acquires dynamically scheduled window information, and receives information of other scheduling units SU-n according to the window information, η>1; Step 403: The terminal acquires the mapping information of the system information block SIB and the SU-n from the information of the SU-1, and acquires all the information according to the correspondence between the SIB and the SU-n indicated by the mapping information. System information.

在步骤 401中， UE可以从物理下行控制信道（PDCCH, Physical Downlink Control Channel )来读取 SU-1的调度信息，也可以通过固定的格式获取 SU-1的调度信息。具体说明如下： In step 401, the UE may read the scheduling information of the SU-1 from the Physical Downlink Control Channel (PDCCH), or acquire the scheduling information of the SU-1 in a fixed format. The specific instructions are as follows:

所述从 PDCCH来读取 SU-1的调度信息具体可以釆用如下两种方式：方式一、在 PDCCH上携带一个信息指示位，长度为 1比特，来指出当前子帧的后面某个子帧上是否有 SU-1的调度信息发送。例如， SU-1的调度信息在子帧（ subframe ) #5,#6,#7上发送，那么在 subframe#5上， PDCCH上会有 1 比特来指示 subframe#6上是否有 SU-1的调度信息发送（0表示没有， 1表示有), 同理对于 subframe#6, submframe#7。 The method for reading the scheduling information of the SU-1 from the PDCCH may be in the following two manners: Mode 1: Carrying an information indicator bit on the PDCCH, the length is 1 bit, to indicate that the subframe is behind the current subframe. Whether there is scheduling information of SU-1 is sent. For example, the scheduling information of SU-1 is sent on subframes #5, #6, #7, then on subframe #5, there will be 1 bit on the PDCCH to indicate whether there is SU-1 on subframe #6. Scheduling information transmission (0 means no, 1 means yes), the same reason for subframe#6, submframe#7.

方式二、在 PDCCH上指示 SU-1长度，该长度是可变的，例如用 2比特来指示，那么就可以表示 1个， 2个， 3个， 4个子帧。 Manner 2: Instructing the SU-1 length on the PDCCH, the length is variable, for example, indicated by 2 bits, then one, two, three, and four subframes can be represented.

此外，所述 UE还可以通过固定的格式获取 SU-1的调度信息。例如 SU-1 的长度是固定的，比如 3个子帧，这样， UE就可以正确的读取 SU-1的调度信息。 In addition, the UE may also acquire scheduling information of SU-1 in a fixed format. For example, the length of SU-1 is fixed, such as 3 subframes, so that the UE can correctly read the scheduling information of SU-1.

在步骤 402中， UE可以通过动态调度的窗口信息接收其它 SU的信息。首先，在一个特定的窗口周期内， UE判断所述窗口周期内是否有动态调度的窗口存在，如果没有动态调度的窗口存在，那么 UE不需要获取和窗口相关的调度信息；如果有动态调度的窗口存在，网络侧将窗口的具体调度信息通知给 UE, 这些调度信息可以包括窗口的开始位置和窗口长度两个参数，也可以仅包括窗口的开始位置。具体说明如下： In step 402, the UE may receive information of other SUs through dynamically scheduled window information. First, in a specific window period, the UE determines whether there is a dynamically scheduled window in the window period. If there is no dynamically scheduled window, the UE does not need to acquire window-related scheduling information; if there is dynamic scheduling The window exists, and the network side notifies the UE of the specific scheduling information of the window. The scheduling information may include two parameters: a start position of the window and a window length, or may only include a start position of the window. The specific instructions are as follows:

如图 5所示，为本发明实施例***信息动态调度的窗口指示示意图。动态调度的窗口存在与否，可以通过窗口指示信息参数获知，具体可以通过下述两种方式实现： As shown in FIG. 5, it is a schematic diagram of a window indication for dynamically scheduling system information according to an embodiment of the present invention. The existence or non-existence of the dynamic scheduling window can be learned through the window indication information parameters, which can be implemented in the following two ways:

方式一、将窗口指示信息位放在 SU-1中，长度为 1比特。 1表示在 SU-1的窗口周期内（固定是 80ms )有动态调度的窗口存在； 0表示在 SU-1的窗口周期内没有动态调度的窗口存在。方式二、将窗口指示信息位放在 MIB中，长度为 1比特。 1表示在 SU-1的窗口周期内（固定是 80ms )有动态调度的窗口存在； 0表示在 SU-1的窗口周期内没有动态调度的窗口存在。 Method 1: The window indication information bit is placed in SU-1, and the length is 1 bit. 1 indicates that there is a dynamically scheduled window in the window period of SU-1 (fixed to 80ms); 0 indicates that there is no dynamically scheduled window in the window period of SU-1. Manner 2: The window indication information bit is placed in the MIB, and the length is 1 bit. 1 indicates that there is a dynamically scheduled window in the window period of SU-1 (fixed to 80ms); 0 indicates that there is no dynamically scheduled window in the window period of SU-1.

此外，还可以将通过隐含指示的方式获得动态调度的窗口是否存在。具体而言，由于 SFN在 LTE***中是一个无线帧的序号，一个无线帧（radio frame ) 的长度是 10ms, 包括 10个子帧，每个子帧的长度是 lms。如图 5所示，例如 SU 的调度窗口在特定的位置，假设是 SFN mod 8=0, 那么当 SFN = 159的时候，不满足 SFN mod 8=0, 那么 UE就知道在这个无线帧上没有调度窗口；当 SFN=160 的时候，满足 SFN mod 8=0,那么 UE就知道在这个无线帧上有调度窗口。因此，如果釆用该方式就可以不需要指示 UE窗口的调度信息。 In addition, it is also possible to obtain whether a dynamically scheduled window exists by means of an implicit indication. Specifically, since the SFN is a sequence number of a radio frame in the LTE system, the length of one radio frame is 10 ms, including 10 subframes, and the length of each subframe is lms. As shown in Figure 5, for example, the scheduling window of the SU is at a specific location, assuming SFN mod 8 = 0, then when SFN = 159, SFN mod 8 = 0 is not satisfied, then the UE knows that there is no VGN mod 8 Scheduling window; When SFN=160, SFN mod 8=0 is satisfied, then the UE knows that there is a scheduling window on this radio frame. Therefore, if this method is used, it is not necessary to indicate the scheduling information of the UE window.

通过上述方式确定有动态调度的窗口存在后，需要提供窗口开始位置指示信息，让 UE知道窗口开始的位置。如图 6所示， ^^如有三个无线帧， SFN分别是 159, 160, 161 ,在 160上发送 SU-1 ,窗口开始位置指示可以有如下三种方式：方式一、如图 7所示，动态调度的窗口开始位置可以固定在 SU-1的子帧开始位置， UE不需要额外的信息来获取动态调度的窗口开始位置。 After determining that there is a dynamically scheduled window in the above manner, it is necessary to provide a window start position indication information, so that the UE knows the position where the window starts. As shown in FIG. 6, if there are three radio frames, SFN is 159, 160, 161, and SU-1 is sent on 160, the window start position indication can be as follows: Mode 1, as shown in FIG. The dynamically scheduled window start position may be fixed at the start position of the SU-1 subframe, and the UE does not need additional information to obtain the dynamically scheduled window start position.

方式二、如图 8所示，动态调度的窗口开始位置和 SU-1调度的子帧开始位置存在一定子帧的偏移量（offset ), 该偏移量指示的位置比较灵活，可以根据情况配置在 SU-1中。对于 FDD***而言，如果在某段时刻 SU-1后面的几个子帧不适合用于发送***信息，那么可以设置所述偏移量为几个子帧；对于 TDD ***而言，由于在某些场合下 SU-1后面的几个子帧会用于发送上行数据，那么通过设置所述偏移量可以让窗口从 SU-1后面的某个子帧开始。特殊的，如果所述偏移量为 0, 那么窗口开始位置就是紧靠 SU-1调度的子帧开始位置。 Manner 2: As shown in FIG. 8, the start position of the dynamically scheduled window and the start position of the sub-frame scheduled by the SU-1 have a certain offset (offset) of the subframe, and the position indicated by the offset is flexible, and may be used according to the situation. Configured in SU-1. For the FDD system, if several subframes after SU-1 are not suitable for transmitting system information at a certain time, the offset may be set to several subframes; for the TDD system, due to some In the case where several subframes behind SU-1 are used to transmit uplink data, the window can be made to start from a subframe after SU-1 by setting the offset. In particular, if the offset is 0, then the window start position is the start position of the sub-frame scheduled next to SU-1.

方式三、如图 9所示，动态调度的窗口开始位置和 SU-1调度的子帧开始位置存在一个固定的偏移量，例如 SU-1是固定在 subframe#5上调度，那么动态调度的窗口开始位置可以设置为 subframe#7 , 即 SU-1之后 2个子帧。这种指示位置比较固定， UE不需要额外的信息来获取动态调度的窗口开始位置。 Manner 3: As shown in FIG. 9, there is a fixed offset between the start position of the dynamically scheduled window and the start position of the SU-1 scheduled subframe. For example, SU-1 is fixed on subframe#5, and then dynamically scheduled. The window start position can be set to subframe#7, which is 2 subframes after SU-1. This indication position is relatively fixed, and the UE does not need additional information to obtain the dynamically scheduled window start position.

当 UE开始从窗口中读取后 , 网络侧还可以通知 UE窗口长度，以便能让 UE 停止窗口的读取。如图 10所示，为在 SU-1中指示窗口长度的示意图。以 SU-1 和一个偏移量作为窗口开始位置为例，如果 SU-1中窗口的长度为 12个子帧，而窗口的偏移量为 2个子帧，那么 UE就可以计算出窗口结束的位置，即在窗口开始后的 12个子帧后窗口结束或者在 SU-1开始后的 15个子帧后窗口结束。 After the UE starts reading from the window, the network side can also notify the UE of the window length so that the UE can stop reading the window. As shown in FIG. 10, it is a schematic diagram indicating the length of the window in SU-1. Take SU-1 and an offset as the window start position, for example, if the length of the window in SU-1 is 12 subframes, The offset of the window is 2 subframes, then the UE can calculate the position of the end of the window, that is, the window ends after 12 sub-frames after the start of the window or ends after 15 sub-frames after the start of SU-1.

另外，还可以利用跳变 Hopping的方式隐含指示窗口的长度。如图 11所示，假设有三个 SU, 分别是 SU-1 , SU-2, SU-3 , 周期分别是 80ms, 160ms, 320ms, 动态调度的窗口的周期是 80ms, 那么如图 11所示，从 SFN=160开始，窗口的长度为， 4个子帧， 1个子帧， 2个子帧， 1个子帧， 4个子帧， 1个子帧 ... ...从中可以看出，窗口的长度变化是有规律跳变的，它的变化周期是 320ms (最大的 SU 的周期长度）。因而，如果釆用跳变 Hopping的方式，那么 UE可以根据这种规律就计算出窗口的长度，例如在 SFN mod 32=0上，窗口长度为 4个子帧，在 SFN mod 32=8上，窗口长度为 1个子帧，在 SFN mod 32=16上，窗口长度为 2个子帧，在 SFN mod 32=24上，窗口长度为 1个子帧。 In addition, you can also use the jump Hopping method to implicitly indicate the length of the window. As shown in FIG. 11, it is assumed that there are three SUs, namely SU-1, SU-2, and SU-3, and the periods are 80 ms, 160 ms, and 320 ms, respectively, and the period of the dynamically scheduled window is 80 ms, as shown in FIG. Starting from SFN=160, the length of the window is 4 subframes, 1 subframe, 2 subframes, 1 subframe, 4 subframes, 1 subframe... As can be seen, the length of the window is changed. Regularly changing, its period of change is 320ms (the maximum SU period length). Therefore, if the Hopping method is used, the UE can calculate the length of the window according to this rule. For example, on SFN mod 32=0, the window length is 4 subframes, and on SFN mod 32=8, the window The length is 1 subframe. On SFN mod 32=16, the window length is 2 subframes. On SFN mod 32=24, the window length is 1 subframe.

在步骤 403中， UE通过 SIB和 SU的映射信息获取每个 SU包含的 SIB信息。因为目前 SU-1的调度周期和位置是固定的，包含的内容是 SIB-1和 SB, 因而内容也是固定的，所以 SIB和 SU的映射信息不包括 SU-1和 SIB-1。 In step 403, the UE acquires the SIB information included in each SU through the mapping information of the SIB and the SU. Since the scheduling period and location of the SU-1 are fixed at present, the contents are SIB-1 and SB, and the content is also fixed, so the mapping information of SIB and SU does not include SU-1 and SIB-1.

假定 SU的个数是 N, N=3 , 表示为 SU-2, SU-3 , SU-4。 Assume that the number of SUs is N, N=3, which is expressed as SU-2, SU-3, SU-4.

SIB的个数是 M, M=7,表示为 SIB-2, SIB-3 , SIB-4, SIB-5, SIB-6, SIB-7, SIB-8。 The number of SIBs is M, M=7, expressed as SIB-2, SIB-3, SIB-4, SIB-5, SIB-6, SIB-7, SIB-8.

SIB和 SU的映射关系是： SU-2包含 SIB-2, SIB-3; SU-3包含 SIB-4, SIB-5, SIB-6; SU-4包含 SIB-7, SIB-8。 The mapping relationship between SIB and SU is: SU-2 contains SIB-2, SIB-3; SU-3 contains SIB-4, SIB-5, SIB-6; SU-4 contains SIB-7, SIB-8.

可以通过如下三种方式实现 SIB和各 SU的映射信息的表示，具体为：方式一、通过位图的方式表示。 The mapping information of the SIB and each SU can be implemented in the following three ways, specifically: Method 1 is represented by a bitmap.

如表 1所示，每个 SU用 7比特来指示 SIB-2 ~ SIB-7的状态， 1表示 SIB在 SU 中， 0表示 SIB不在 SU中。 As shown in Table 1, each SU uses 7 bits to indicate the status of SIB-2 ~ SIB-7, 1 means SIB is in SU, 0 means SIB is not in SU.

通过计算可知，通过方式一位图的方式表示 SIB和 SU的映射信息的开销 3*7=21bit。 According to the calculation, the overhead of the mapping information of the SIB and the SU is represented by a one-bit mode. 3*7=21bit.

方式二、通过枚举的方式表示。 Method 2, represented by enumeration.

如表 2所示，用 2比特表示所有的 SU, 例如： 00表示 SU-1 , 01表示 SU-2, As shown in Table 2, all SUs are represented by 2 bits, for example: 00 means SU-1, 01 means SU-2,

10表示 SU-3 , 11表示 SU-4。每个 SIB存在该 SIB所在 SU的信息。 10 means SU-3 and 11 means SU-4. Each SIB has information about the SU where the SIB is located.

表 2

Table 2

通过计算可知，通过方式二枚举的方式表示 SIB和 SU的映射信息的开销 2*7=14bit。 It can be seen from the calculation that the overhead of the mapping information of SIB and SU is represented by the mode two enumeration 2*7=14 bits.

方式三、通过另一种枚举的方式表示。 Mode 3, represented by another enumeration.

如表 3所示，用 2比特表示所有的 SU, 例如： 00表示 SU-1 , 01表示 SU-2, 10表示 SU-3 , 11表示 SU-4。用 3比特表示所有的 SIB, 例如： 000表示 SIB-1 , 001表示 SIB-2, 010表示 SIB-3, 011表示 SIB-4, 100表示 SIB-5, 101表示 SIB-6, 110 表示 SIB-7, 111表示 SIB-8, 每个 SU枚举该 SU包含的 SIB。 As shown in Table 3, all SUs are represented by 2 bits, for example: 00 means SU-1, 01 means SU-2, 10 means SU-3, and 11 means SU-4.
