技术领域
本公开涉及通信领域，尤其涉及一种信息发送方法、装置、终端及存储介质。
背景技术
为满足蜂窝物联网(C-IoT，Cellular Internet of Things)需求，第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)组织研究制定了窄带物联网(NB-IoT，NarrowBand-Cellular Internet of Things)的技术方案。其中，所述NB-IoT系统关注低复杂度和低吞吐量的射频接入技术，主要的研究目标包括：改善的室内覆盖，巨量低吞吐量用户设备的支持，低的延时敏感性，超低设备成本，低的设备功率损耗以及网络架构。
在目前制定的NB-IoT系统方案中，不支持专用的调度请求，如果终端有数据需要发送，且没有建立有效的窄带上行业务信道(NPUSCH)信道时，需要通过随机接入请求过程来发送数据请求，即调度请求。
但是，对于NB-IoT系统，NB-IoT终端数量大且终端的业务模型类似，上行数据请求的并发性高；通过随机接入过程来发送数据请求，将会对NB-IoT系统造成很大的冲击，发生碰撞的概率很大。
因此，NB-IoT系统如何高效、低碰撞率地发送调度请求是目前亟待解决的问题。
发明内容

具体实施方式
下面结合附图及实施例对本公开再作进一步详细的描述。
NB-IoT系统的上下行的发射带宽都是180kHz，与长期演进(LTE，Long Term Evolution)系统中一个物理资源块(PRB，Physical Resource Block)的带宽相同，这有利于在NB-IoT系统中重用现有LTE系统的有关设计。另外，NB-IoT系统还支持3种不同的操作模式：1)独立(Stand-alone)操作，例如利用当前被GERAN(GSM EDGE Radio Access Network)系统使 用的频谱来代替1个或多个全球移动通信系统(GSM，Global System for Mobile Communication)载波；2)保护带(Guard band)操作，例如利用在一个LTE载波保护带范围内的未被使用的资源块；3)带内(In-band)操作，例如利用在一个正常LTE载波范围内的资源块。
目前制定的NB-IoT系统方案中，当终端建立有NPUSCH信道时可通过NPUSCH信道携带缓存状态报告(BSR，Buffer Status Report)来通知基站分配新的NPUSCH资源。但是如果终端没有建立有效的NPUSCH信道，则需要通过随机接入请求过程来发送数据请求。然而，在随机接入过程中，终端随机选择一个前导序列向网络侧发起随机接入过程，如果同一时刻多个终端使用同一个前导序列发起随机接入过程，就会发生冲突。然而，对于NB-IoT系统，NB-IoT终端数量大且终端的业务模型类似，所以上行数据请求的并发性高；因此通过随机接入过程来发送数据请求，这将会对NB-IoT系统造成很大的冲击，发生碰撞的概率很大。
基于此，在本公开的各种实施例中：确定调度请求对应的物理信号/物理信道的发送资源；在所述发送资源上发送所述物理信号/物理信道；所述调度请求用于请求分配数据的发送资源。
由于采用物理信号/物理信道来发送调度请求，而不是通过随机接入过程来发送调度请求，就避免了多个终端可能会使用一个前导序列所带来的冲突的问题，能够高效、低碰撞率地发送调度请求，大大增加了发送成功的机率。也就是说，通过物理信号/物理信道向基站发送调度请求，冲突率低，相对于随机接入过程其时延更小，解决了NB-IoT系统中大量NB-IoT终端通过随机接入过程发起调度请求的冲突和拥塞问题。
实施例一
本公开实施例信息的发送方法，应用于终端，如图1所示，该方法包括以下步骤：
步骤101：所述终端确定调度请求对应的物理信号/物理信道的发送资源；
这里，所述物理信号的序列为以下之一：

所述终端调度请求对应的物理信号/物理信道的发送资源，包括：
所述终端确定所述物理信号/物理信道的发送资源复用ACK/NACK的发送资源。
实际应用时，所述终端还可以通过高层信令配置的方式确定所述物理信号/物理信道的发送资源。
其中，所述通过高层信令配置的方式确定调度请求对应的物理信号/物理信道的发送资源，包括：
通过无线资源控制(RRC，Radio Resource Control)信令携带的配置参数配置所述物理信号/物理信道的发送资源；
所述配置参数包括以下参数至少之一：

这里，实际应用时，通过所述配置参数配置所述物理信号/物理信道的发送资源时，所述置配置参数未包含所述物理信号/物理信道的频域子载波位置时，则确认频域子载波位置为固定或预定义的缺省值。
通过所述配置参数配置所述物理信号/物理信道的发送资源时，利用1、2、3、4或6比特的子载波偏置信息来确定所述物理信号/物理信道的频域子载波位置。
通过所述配置参数配置所述物理信号/物理信道的发送资源时，当子载波间隔为3.75kHz时，确定的所述物理信号/物理信道的频域子载波位置I f为以下之一：
I f＝37-子载波偏置；I f＝45-子载波偏置；I f＝46-子载波偏置；I f＝子载波偏置。

I f＝4+子载波偏置；I f＝子载波偏置；I f＝11-子载波偏置。
步骤102：所述终端在所述发送资源上发送所述物理信号/物理信道。
具体地，所述终端向基站发送所述物理信号/物理信道。
这里，所述调度请求用于请求分配数据的发送资源。
实际应用时，所述物理信号/物理信道满足以下特征至少之一：
在频域上占据1个子载波，即采用单载波的发送方式(single tone)；
所占据的时域长度＝最小时域长度×重复因子N。
其中，所述最小时域长度可以满足以下条件之一：
对于15kHz的子载波间隔，所述物理信号/物理信道所占据的最小时域长度为1ms或者2ms；
对于3.75kHz的子载波间隔，所述物理信号/物理信道所占据的最小时域长度为2ms或4ms或6ms或8ms；
对于3.75kHz的子载波间隔，所述物理信号所占据的最小长度为至少一个NPRACH符号组的长度；其中，所述NPRACH符号组的长度＝循环前缀(CP)+5个正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)符号的长度。
其中，实际应用时，所述至少一个NPRACH符号组的长度可以为1、2或者4个NPRACH符号组的长度。
在一实施例中，步骤101的具体实现可以包括：
判断配置的所述物理信号/物理信道的发送资源与ACK/NACK的发送资源是否存在冲突；
当存在冲突时，依据冲突解决策略确定所述物理信号/物理信道的发送资源。
具体地，当配置的所述物理信号/物理信道的发送资源大小与ACK/NACK信号的发送资源大小相同，所述请求物理信号/物理信道与ACK/NACK信号的发送资源的时域位置对齐，且接收到下行数据时，所述终端确定所述物理信号/物理信道的发送资源为所述ACK/NACK信号的发送资源。
相应地，在步骤102中，所述终端在所述下行数据对应的ACK/NACK信号的发送资源上同时携带ACK/NACK信号和所述物理信号/物理信道；并利用正交相移键控(QPSK，Quadrature Phase Shift Keying)或∏/4-QPSK对所需发送的ACK/NACK信号和所述物理信号/物理信道进行调制。
其中，对于基站，首先在配置的所述物理信号/物理信道的发送资源上检测所述物理信号/物理信道。如果基站在配置的所述物理信号/物理信道的发送资源上检测到了所述物理信号/物理信道，则在ACK/NACK信号的发 送资源上检测∏/2-二进制相移键控(BPSK，Binary Phase Shift Keying)调制的ACK/NACK信号；如果基站在配置的所述物理信号/物理信道的发送资源上没有检测到所述物理信号/物理信道，则在ACK/NACK信号的发送资源上检测QPSK或∏/4-QPSK调制的联合编码的ACK/NACK信号和调度请求信号。
这里，当配置的所述物理信号/物理信道的发送资源大小与ACK/NACK信号的发送资源大小相同，所述请求物理信号/物理信道与ACK/NACK信号的发送资源的时域位置对齐，且未接收到下行数据时，所述终端确定所述物理信号/物理信道的发送资源为配置的发送资源；
相应地，在步骤102中，所述终端在所述配置的发送资源上发送所述物理信号/物理信道。
其中，实际应用时，所述物理信号/物理信道还可以仅在有ACK/NACK信号发送时才发送，此时所述ACK/NACK信号与所述物理信号/物理信道一起传输。
基于此，在一实施例中，步骤101的具体实现可以包括：
当配置的所述物理信号/物理信道的发送资源大小与ACK/NACK信号的发送资源大小相同，所述请求物理信号/物理信道与ACK/NACK信号的发送资源的时域位置对齐，确定所述物理信号/物理信道的发送资源为所述ACK/NACK信号的发送资源；

在一实施例中，步骤101的具体实现可以包括：
当配置的所述物理信号/物理信道的发送资源与ACK/NACK信号的发送资源在时域上部分重叠，且接收到下行数据时，确定在下行数据对应的ACK/NACK信号的发送资源上发送ACK/NACK信号，并丢弃所述物理信号/物理信道。
这里，当配置的所述物理信号/物理信道的发送资源与ACK/NACK信号的发送资源在时域上部分重叠，且未接收到下行数据时，确定所述物理信号/物理信道的发送资源为配置的发送资源；
相应地，在步骤102中，在所述配置的发送资源上发送所述物理信号/物理信道。
其中，实际应用时，当没有配置所述物理信号/物理信道的发送资源，且需要调度请求时，启动定时器，所述定时器超时前，当没有ACK/NACK信号发送时，通过触发随机接入过程来传输所述调度请求。
这里，所述定时器的时长可以根据需要来设置。
当发送所述物理信道时，发送所述物理信号的每个时隙可以由6个数据符号和1个导频符号构成。
本公开实施例提供的信息发送方法，确定调度请求对应的物理信号/物理信道的发送资源；在所述发送资源上发送所述物理信号/物理信道；所述调度请求用于请求分配数据的发送资源，由于采用物理信号/物理信道来发送调度请求，而不是通过随机接入过程来发送调度请求，能够高效、低碰撞率地发送调度请求，大大增加了发送成功的机率。也就是说，通过物理信号/物理信道向基站发送调度请求，冲突率低，相对于随机接入过程其时延更小，解决了NB-IoT系统中大量NB-IoT终端通过随机接入过程发起调度请求的冲突和拥塞问题。
另外，通过高层信令配置的方式确定调度请求对应的物理信号/物理信道的发送资源，或者确定所述物理信号/物理信道的发送资源复用ACK/NACK的发送资源，或者判断配置的所述物理信号/物理信道的发送资源与ACK/NACK的发送资源是否存在冲突；当存在冲突时，依据冲突解决策略确定所述物理信号/物理信道的发送资源，通过这些具体的确定方式，能够进一步高效、低碰撞率地发送调度请求，从而进一步减少时延。

这里，实际应用时，如果调度请求物理信号的发送位置配置参数不包含调度请求物理信号的频域子载波位置，则频域子载波位置采用固定或预定义的缺省值。如果调度请求物理信号的发送位置配置参数不包含重复因子N，则调度请求物理信号的重复因子N采用固定或预定义的缺省值，缺省值为1。
其中，实际应用时，可以通过1、2或3比特的子载波偏置信息来指示调度请求物理信号的频域子载波位置。对于3.75kHz子载波间隔，调度请求物理信号的频域子载波位置为：
I f＝37-子载波偏置；或者I f＝45-子载波偏置；或者I f＝46-子载波偏置；或者I f＝子载波偏置。
对于15kHz子载波间隔，调度请求物理信号的频域子载波位置为：
I f＝4+子载波偏置；或者I f＝子载波偏置；或者I f＝11-子载波偏置。
在所配置的调度请求物理信号的发送资源上，单用户的调度请求物理信号独占该资源或多用户的调度请求物理信号复用在该资源。

2、Walsh序列+ZC序列
具体地，所述Walsh序列长度为16，所述ZC序列长度为12。如图3所示，Walsh序列和ZC序列通过时分方式在调度请求信号资源中复用形成的序列。
3、Walsh序列+OCC序列
具体地，所述Walsh序列长度为4，所述OCC序列为3阶OCC序列。如图4所示，所述调度请求物理信号由4阶Walsh序列和3阶OCC序列通过时分方式组成的组合序列重复4次生成的序列。
4、NB-IoT中发送ACK/NACK信号的序列
这里，实际应用时，如果调度请求物理信号为ZC序列，则通过根序列组进行小区间干扰随机化。
如果调度请求物理信号为Walsh序列+ZC序列，或者为Walsh序列+OCC序列，则通过PN序列或Gold序列对所述调度请求物理信号进行扰码。
通过本实施例所述的方法，NB-IoT终端在预配置的资源位置上通过调度请求物理信号向基站发送调度请求，冲突率低，相对于随机接入过程时延更小，解决了NB-IOT系统大量NB-IoT终端通过随机接入过程发起调度请求的冲突和拥塞问题。

步骤501：终端配置发送调度请求物理信号的发送资源；
步骤502：终端通过在所述发送资源上发送NPRACH信号向基站发送调度请求。
也就是说，所述调度请求物理信号为NPRACH信号。
其中，所述调度请求物理信号在频域上占据1个子载波，即所述调度请求物理信号的发送方式为single tone发送方式，子载波间隔3.75kHz。所述调度请求物理信号/物理信道所占据的时域长度＝最小时域长度×重复因子N。所述调度请求物理信号所占据的最小时域长度为1个或多个NPRACH符号组的长度，优选为1，2或4。
这里，NPRACH符号组的长度＝CP+5个OFDM符号的长度。

其中，实际应用时，如果调度请求物理信号的发送位置配置参数不包含调度请求物理信号的频域子载波位置，则频域子载波位置采用固定或预定义的缺省值。如果调度请求物理信号的发送位置配置参数不包含重复因子N，则调度请求物理信号的重复因子N采用固定或预定义的缺省值，缺省值为1。
这里，实际应用时，可以通过1、2或3比特的子载波偏置信息来指示调度请求物理信号的频域子载波位置。调度请求物理信号的频域子载波位 置为：

步骤601：终端配置调度请求物理信道的发送资源；
步骤602：终端通过在发送资源上发送调度请求物理信道向基站发送调度请求。
其中，所述调度请求物理信道在频域上占据1个子载波，即所述调度请求物理信道的发送方式为single tone发送方式。调度请求物理信道所占据的时域长度＝最小时域长度×重复因子N，其中N为大于或等于1的整数。对于15kHz的子载波间隔，所述调度请求物理信道所占据的最小时域长度为1ms或者2ms(4个时隙，每个时隙包含7个OFDM符号)。对于3.75kHz的子载波间隔，所述调度请求物理信道所占据的最小时域长度为2ms、4ms、6ms或者8ms(4个时隙，每个时隙包含7个OFDM符号)。
这里，终端通过RRC信令携带的发送位置配置参数配置调度请求物理信道的发送资源，配置参数包括以下参数至少之一：
调度请求物理信道的时域发送周期；
调度请求物理信道在发送周期中的时域偏置；
调度请求物理信道的频域子载波位置；
调度请求物理信道的重复因子N。
其中，实际应用时，如果调度请求物理信道的发送位置配置参数不包含调度请求物理信道的频域子载波位置，则频域子载波位置采用固定或预定义的缺省值。
实际应用时，可以通过1、2或3比特的子载波偏置信息来指示调度请求物理信道的频域子载波位置。对于3.75kHz子载波间隔，调度请求物理信道的频域子载波位置为：
I f＝37-子载波偏置；或者I f＝45-子载波偏置；或者I f＝46-子载波偏置；或者I f＝子载波偏置。
对于15kHz子载波间隔，调度请求物理信道的频域子载波位置为：
I f＝4+子载波偏置；或者I f＝子载波偏置；或者I f＝11-子载波偏置。
在所配置的调度请求物理信道的发送位置上，单用户的调度请求物理信道独占该资源位置或多用户的调度请求物理信道复用在该资源位置。
调度请求物理信道由数据+导频组成。
实际应用时，当有调度请求发送时，在调度请求物理信道上发送数据+导频信号；当没有调度请求发送时，不发送数据+导频信号。
每个时隙由6个数据符号+1个导频符号构成。
通过本实施例所述的方法，NB-IoT终端在预配置的资源位置上通过调度请求物理信道向基站发送调度请求，冲突率低，相对于随机接入过程时延更小，解决了NB-IOT系统大量NB-IoT终端通过随机接入过程发起调度请求的冲突和拥塞问题。
实施例五
本实施例提供了一种调度请求的发送方法，图7是根据本公开实施例 的ACK/NACK信号和调度请求冲突的处理流程示意图。如图7所示，该方法包括如下步骤：
步骤701：终端判断ACK/NACK的发送资源和调度请求的发送资源的冲突情况；
步骤702：根据预定义的规则处理ACK/NACK信号和调度请求的冲突。
这里，所述预定义的规则包括以下之一：
当所配置的调度请求物理信号/物理信道的发送资源大小和发送ACK/NACK信号的资源大小相同，并且调度请求物理信号/物理信道和ACK/NACK信号的发送资源的时域位置对齐时，如果终端接收到下行数据，则终端在下行数据对应的ACK/NACK信号的发送资源上同时携带ACK/NACK信号和调度请求；并利用QPSK或∏/4-QPSK对所需发送的ACK/NACK信号和调度请求进行调制。如果终端未收到下行数据，则终端在所配置的调度请求物理信号/物理信道的发送资源上发送调度请求。
对于基站来说，当所配置的调度请求物理信号/物理信道的发送资源大小和发送ACK/NACK信号的资源大小相同，并且调度请求物理信号/物理信道和ACK/NACK信号的发送资源的时域位置对齐时，基站首先在调度请求物理信号/物理信道配置的发送资源上检测调度请求。如果基站在调度请求物理信号/物理信道配置的发送资源上检测到了调度请求，说明调度请求物理信号/物理信道没有在ACK/NACK信号的发送资源与ACK/NACK信号联合发送，ACK/NACK的发送资源上仅仅携带了ACK/NACK信号，此时基站在ACK/NACK信号的发送资源上检测∏/2-BPSK调制的ACK/NACK信号；如果基站在调度请求物理信号/物理信道配置的发送资源上没有检测到调度请求，说明调度请求物理信号/物理信道在ACK/NACK信号的发送资源与ACK/NACK信号联合发送，此时基站在ACK/NACK信号的发送资源上检测QPSK或∏/4-QPSK调制的联合编码的ACK/NACK信号和调度请求信号。
当所配置的调度请求物理信号/物理信道的发送资源和发送ACK/NACK信号的资源在时域上部分重叠时，如果终端接收到下行数据，则终端在下行数据对应的ACK/NACK信号的发送资源上发送ACK/NACK 信号，丢弃调度请求；否则终端在所配置的调度请求物理信号/物理信道的发送资源上发送调度请求。
当没有配置调度请求物理信号/物理信道的发送资源，且终端有调度请求时，定时器开始计时，从定时器开始计时到定时器超过阈值期间，当终端没有ACK/NACK信号发送时，则终端通过触发随机接入过程来传输调度请求信息。
通过本实施例所述的方法，NB-IoT终端在预配置的资源位置，并结合ACK/NACK信号的资源情况，通过调度请求物理信号/物理信道向基站发送调度请求，冲突率低，相对于随机接入过程时延更小，解决了NB-IOT系统大量NB-IoT终端通过随机接入过程发起调度请求的冲突和拥塞问题。
