其中，所述MIB中包含多个配置参数，包括***带宽信息、传输所述MIB的无线帧的帧号、物理混合自动重传指示信道(Physical HARQ Indication Channel，PHICH)配置信息，以及保留信息。
由于上述MIB信息中包含有多个配置参数，因此，基站传输所述MIB的信息开销过高，造成基站的功耗高。
发明内容

本发明提供的具体技术方案如下：
一方面，本发明实施例提供了一种信息传输方法，该方法包括：基站生成包含第一带宽指示信息和无线帧配置域的主信息块MIB，其中，所述第一带宽指示信息用于指示***带宽所在的第一范围，所述无线帧配置域表示发送所述MIB的无线帧中是否配置有以下至少一项或组合：***信息块SIB1的资源、物理随机接入信道PRACH资源、寻呼Paging消息的资源，以及多播/组播单频网络MBSFN资源；所述基站占用所述无线帧内的时频资源发送所述MIB。
采用上述方法，基站生成包含第一带宽指示信息和无线帧配置域的MIB，并占用一个无线帧内的时频资源发送所述MIB。相对于传统的MIB中包含的***带宽信息、传输MIB的无线帧的帧号、PHICH配置信息等多个配置参数，由于本发明实施例中基站传输的MIB中包含第一带宽指示信息和无线帧配置域两个配置参数，因此，降低了所述基站传输所述MIB的信息开销，降低了所述基站的功耗。且在***可用带宽划分为多个范围后，所述基站发送包含所述第一带宽指示信息的所述MIB时，所述终端设备获得所述MIB，即可确定***带宽所在的第一范围。通过上述方法，本发明实施例可以尽量降低MIB信息开销。

本发明实施例中，基站生成包含第一带宽指示信息和无线帧配置域的MIB，并占用预设的时频资源，通过无线帧发送所述MIB。相对于传统的MIB中包含的***带宽信息、传输MIB的无线帧的帧号、PHICH配置信息等多个配置参数，由于本发明实施例中基站传输的MIB中包含第一带宽指示信息和无线帧配置域两个配置参数，因此，降低了所述基站传输所述MIB的信息开销，降低了所述基站的功耗。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、本发明实施例涉及的基站，是将终端设备接入到无线网络的设备，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)、接入点(Access Point，AP)等。
2)、本发明涉及的终端设备，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备、可穿戴设备、计算设备、移动台(Mobile Station，MS)或连接到无线调制解调器的其他处理设备等，以及经无线接入网与一个或多个核心网进行通信的移动终端。
3)、“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本发明实施例提供的信息传输方法，适用于如图1所示的信息传输***的网络架构中，在该网络架构中包括基站101，以及至少一个终端设备102，其中，
所述基站101根据当前***配置生成MIB，并周期性将所述MIB通过无线帧进行广播，以及通过所述无线帧广播以下任意一项或组合：***信息块(System Information Block，SIB)1、寻呼(Paging)消息、多播/组播单频网络(Multimedia Broadcast multicast service Single Frequency Network，MBSFN)资源和物理随机接入信道(Physical Random Access Channel，PRACH)资源等，其中所述MIB中用于通知所述终端设备发送所述MIB的无线帧的配置信息。
每个终端设备102，在预设的带宽范围内检索所述MIB，在一个无线帧中检索到所述MIB时，根据所述MIB，获取所述无线帧的配置信息，并根据所述无线帧的配置信息，检索SIB1、Paging消息、MBSFN资源和PRACH资源等。
每个终端设备102通过上述方式获取基站广播的***消息，可以保证每个终端设备 102能够获取接入网络必要的当前***配置，保证了每个终端设备102在空闲状态下的移动性管理。
在传统的时分双工长期演进(Time Division Duplex Long Term Evolution，TDD-LTE)***中，一个无线帧的时间长度是10秒，一个无线帧可以分成10个长度为1秒的子帧。其中子帧分为两种类型：上行子帧和下行子帧，其中，上行子帧包含的符号全都用于上行传输，下行子帧包含的符号全都用于下行传输。上行传输和下行传输的数据在同一个无线帧内不同的子帧上传输。TDD-LTE中支持不同的上下行时间配比，可以根据不同的业务类型，调整上下行子帧配比，以满足上下行非对称业务的需求。在同一无线帧内，不同的上下行子帧的配置如表1所示：
表1TDD-LTE***的无线帧上下行子帧配比
Figure PCTCN2017079603-appb-000001
在表1中，D表示下行子帧，U表示上行子帧，S表示特殊子帧。
在TDD-LTE***中，***信息MIB、SIB1以及Paging消息等信息占用固定的下行子帧中的时频资源传输信息。其中，MIB占用0号子帧的物理下行共享信道(Physical Downlink Share Channel，PDSCH)资源发送，SIB1占用5号子帧的PDSCH资源发送，Paging消息可以占用0、1、5和6号子帧的PDSCH资源发送，而PRACH资源占用的子帧必须为上行子帧。显然，在如表1所示的传统的无线帧上下行子帧配比下，通过上述静态的方式发送***消息、Paging消息以及PRACH资源等，限制了上述消息所占用的子帧类型，导致***无法动态适应不断发展的业务类型以及变化的应用环境，降低了***的灵活性。
在传统的TDD-LTE***中，MIB占用0号子帧的4个符号的PDSCH资源发送，所述MIB中包含24比特(bits)的内容，其中，3bits用于指示***带宽，8bits用于指示传输所述MIB的当前无线帧的帧号，3bits用于指示PHICH配置信息，10bits的保留信息。基站传输所述MIB的信息开销过高，造成基站的功耗较高。
本发明实施例提供的一种信息传输方法，该方法可以但不限于在LTE或LTE演进(LTE-Advanced，LTE-A)***中，该方法应用于如图1所示的网络架构中，本发明实施例涉及的基站可以为该网络架构中的基站101，参阅图2所示，该方法的处理流程包括：
步骤201：基站生成MIB，所述MIB中包含第一带宽指示信息和无线帧配置域，其中，所述第一带宽指示信息用于指示***带宽所在的第一范围，所述无线帧配置域表示发送所述MIB的无线帧中是否配置有以下至少一项或组合：SIB1的资源、PRACH资源、Paging消息的资源，以及MBSFN资源。
可选的，所述基站是根据当前***配置，生成所述MIB的。例如，根据当前***带宽生成所述第一带宽指示信息，以及根据当前***的资源配置信息，生成无线帧的配置 信息，根据所述无线帧的配置信息，生成所述无线帧配置域。
可选的，所述MIB包含4bits，其中，所述第一带宽指示信息占用1bit或2bits或3bits，所述无线帧配置域占用1bit。
由于所述第一带宽指示信息占用1bit-3bits，所以当所述第一带宽指示信息占用1bit时，所述MIB中还包含2bits保留信息；当所述第一带宽指示信息占用2bits时，所述MIB中还包含1bit保留信息；当所述第一带宽指示信息占用3bits时，所述MIB中不包含保留信息。
传统的MIB中，固定有3bits用于指示***带宽，因此用于指示***带宽的信息开销比较大。且本领域人员了解，为了提高***的数据传输速率和***容量，最常用的方法为增加***带宽的种类。目前3bits的内容组成8种编码，最多指示8种***带宽，当***带宽种类过多(例如***带宽扩展为10种)时，通过3bits的内容无法直接指示准确的一种***带宽。
为了避免上述问题，降低信息开销以及提高终端设备通过MIB获得的***带宽的准确度，在本发明实施例中，将***可用的带宽进行划分，划分为多个范围，例如，当***可用带宽为1兆(M)-10M时，可以将***可用的带宽划分为两个范围——1M-5M，5M-10M，当所述基站确定***带宽在5M-10M范围内，则所述基站生成指示5M-10M的第一带宽指示信息。显然，所述第一带宽指示信息指示的所述第一范围内包括预设的至少一个***可用带宽，且所述至少一个***可用带宽中包含当前的所述***带宽。
所述第一带宽指示信息所述占用的bit数目，是根据***可用带宽划分的范围的数目确定的，当***可用带宽划分为2个范围，那么所述第一带宽指示信息可以占用1bit，例如该1bit为0表示一个范围，该1bit为1表示另一个范围。当***可用的带宽划分为3-4个范围时，所述第一带宽指示信息占用2bits；当***可用的带宽划分5-8个范围时，所述第一带宽指示信息占用3bits。
根据以上论述可知，由于所述第一带宽指示信息最多占用3bits，所以***可用带宽最多划分为8个范围。
在本发明实施例中，在***可以将***可用带宽划分为多个范围后，所述基站以及所述终端设备中均维护有所述第一带宽指示信息所有的取值以及每个取值对应的***带宽所在的范围。这样，所述基站发送包含所述第一带宽指示信息的所述MIB时，所述终端设备获得所述MIB，即可确定***带宽所在的第一范围。通过上述方法，本发明实施例可以尽量降低MIB信息开销。
在本发明实施例中，通过所述无线帧配置域表示发送所述MIB的无线帧中是否配置有以下至少一项或组合：SIB1的资源、PRACH资源、Paging消息的资源，以及MBSFN资源，因此，后续终端设备在一个无线帧中检索到所述MIB后，可以直接根据所述无线帧配置域，确定所述无线帧的配置信息，根据所述无线帧的配置信息，判定是否执行以下操作：在所述无线帧中检索SIB1、在所述无线帧中检索Paging消息、在所述无线帧中检索MBSFN资源以及通过所述无线帧发送PRACH消息，进一步降低了所述基站传输所述MIB信息的开销，同时所述终端设备可以但不限于通过根据所述无线帧配置域获得的无线帧的配置信息判定是否执行上述四项操作中相应的操作，避免了在所述无线帧未配置上述四项内容中部分内容时，所述终端设备却执行未配置的内容对应的操作，从而降低了所述终端设备的功耗。
可选的，所述无线帧配置域所占用的1bit取值设定为第一值时，无线帧配置域表示发送所述MIB的无线帧中配置有上述四项中的至少一项或组合；所述无线帧配置域所占用的1bit取值设定为第二值时，无线帧配置域表示所述无线帧中未配置有上述四项中的至少一项或组合。所述第一值和所述第二值为不同的数值，可选的，所述第一值和所述第二值均可以为0或1，本发明对此不做限定。
综上所述，本发明实施例中基站发送的所述MIB包含4bits的内容，相对于传统的MIB包含24bits的内容，本发明实施例基站发送所述MIB，降低了基站传输所述MIB的信息开销，从而降低了基站的功耗。
步骤202：所述基站占用所述无线帧内的时频资源发送所述MIB。
所述时频资源，可以是所述无线帧内设定的符号，且所述设定的符号为下行符号。
由于所述无线帧配置域表示发送所述MIB的无线帧中是否配置有以下至少一项或组合：SIB1的资源、PRACH资源、Paging消息的资源，以及MBSFN资源。具体包括以下情况或组合：
第一种情况：所述无线帧配置域中表示所述无线帧中是否配置有SIB1的资源；
第二种情况：所述无线帧配置域表示所述无线帧中是否配置有Paging消息的资源；
第三种情况：所述无线帧配置域表示所述无线帧中是否配置有MBSFN资源；
第四种情况：所述无线帧配置域表示所述无线帧中是否配置有PRACH资源。
在第一种情况下：
当所述无线帧配置域表示所述无线帧中配置有SIB1的资源时，所述方法还包括：所述基站通过所述无线帧中设定第一资源集合中的资源发送SIB1；
当所述无线帧配置域表示所述无线帧中未配置有SIB1的资源时，所述方法还包括：所述基站不通过所述无线帧发送SIB1。
其中，可选的，在所述基站发送所述SIB1时，所述SIB1中包含所述无线帧的帧号信息、第二带宽指示信息，其中，所述第二带宽指示信息用于指示在所述第一范围内的***带宽。
其中，所述SIB1中还包含传统的信息，例如小区接入相关信息、小区选择信息、***消息窗口长度、最大发送功率，***信息改变标志位、***消息调度列表、TDD配置信息以及频率带宽指示等终端设备小区驻留所需信息以及对其他***信息块的调度信息，保证所述终端设备可以根据所述SIB1中驻留在小区中，进入连接状态，以及接收其他***信息块。
由于所述MIB中未包含发送所述无线帧的帧号信息，因此，所述终端设备无法根据检索到的所述MIB获得所述无线帧的帧号。且所述无线帧的帧号信息用于通知所述终端设备***的时间信息，使所述终端设备可以进行小区同步。所述SIB1中包含所述无线帧的帧号信息，可以使所述终端设备获得所述无线帧的帧号，从而进行小区同步操作，避免由于降低所述MIB的信息开销，导致所述无线帧的帧号信息无法发送至所述终端设备的问题。
由于所述MIB中包含的第一带宽指示信息指示了***带宽所在的第一范围，因此，所述终端设备在接收到所述MIB后，只能确定一个比较大的***带宽所在的范围，而无法精确地确定***带宽。尤其是当***可用带宽范围较大时，仅将***可用带宽范围进行一次划分，划分的每个范围都比较大，因此，需要对第一次划分的每个范围内确认系 统带宽，即首先对***可用带宽进行粗粒度的一次划分，划分为2-8个大范围，然后，对每个粗粒度的范围进行细粒度的二次确认。
所述SIB1中包含的所述第二带宽指示信息指示在所述第一范围内的具体的***带宽。这样，所述终端设备在接收到所述SIB1以后，可以根据所述第二带宽指示信息，精确地确定***带宽，以使所述终端设备后续可以在确定的***带宽内与所述基站进行数据交互。
在本发明实施例中，所述基站降低了所述MIB的信息开销，但是为了保证所述终端设备的工作正常运行，所述基站在所述SIB1中增加了所述无线帧的帧号信息、所述第二带宽指示信息两项信息，即所述基站增加了所述SIB1的信息开销。这是因为所述SIB1是通过下行控制信令调度的，它并没有固定的频域资源的限制，只有时域资源的限制，本发明实施例通过在所述SIB1中增加两项信息，可以打开所述SIB1在时域资源上的限制，增加SIB1传输的灵活性。
在第二种情况下：
当所述无线帧配置域表示所述无线帧中配置有Paging消息的资源时，所述方法还包括：所述基站通过所述无线帧中设定第二资源集合中的资源发送Paging消息；
当所述无线帧配置域表示所述无线帧中未配置有Paging消息的资源时，所述方法还包括：所述基站不通过所述无线帧发送Paging消息。
在第三种情况下：
当所述无线帧配置域表示所述无线帧中配置有MBSFN资源时，所述方法还包括：所述基站将所述无线帧中设定第三资源集合中的资源设置为MBSFN资源；
当所述无线帧配置域表示所述无线帧中未配置有MBSFN资源时，所述方法还包括：所述基站不将所述无线帧中的资源设置为MBSFN资源。
在第四种情况下：
当所述无线帧配置域表示所述无线帧中配置有PRACH资源时，所述方法还包括：所述基站将所述无线帧中设定第四资源集合中的资源设置为PRACH资源；
当所述无线帧配置域表示所述无线帧中未配置有PRACH资源时，所述方法还包括：所述基站不将所述无线帧中的资源设置为PRACH资源。
在以上四种情况中的所述第一资源集合、所述第二资源集合、所述第三资源集合以及所述第四资源集合可以为子帧集合、符号集合等，本发明对此不做限定，且本发明对每个资源集合中的子帧或符号的数目不做限定。这样，在本发明实施例中，SIB1、Paging消息、MBSFN资源以及PRACH资源不再占用固定的下行子帧中的时频资源，在所述基站传输上述信息时，可以根据业务类型以及应用环境，动态调整上述信息所占用的资源，提高了***的灵活性。
采用本发明上述实施例中的信息传输方法，基站生成包含第一带宽指示信息和无线帧配置域的MIB，并占用一个无线帧内的时频资源发送所述MIB。相对于传统的MIB中包含的***带宽信息、传输MIB的无线帧的帧号、PHICH配置信息等多个配置参数，由于本发明实施例中基站传输的MIB中包含第一带宽指示信息和无线帧配置域两个配置参数，因此，降低了所述基站传输所述MIB的信息开销，降低了所述基站的功耗。
本发明实施例还提供了一种信息传输方法，该方法可以但不限于在LTE或LTE-A***中，该方法应用于如图1所示的网络架构中，本发明涉及的终端设备可以为该网络架构 中的终端设备102，参阅图3所示，该方法的处理流程包括：
步骤301：终端设备在预设的带宽范围内检索MIB，所述MIB中包含第一带宽指示信息和无线帧配置域，其中，所述第一带宽指示信息用于指示***带宽所在的第一范围，所述无线帧配置域表示发送所述MIB的无线帧中是否配置有以下至少一项或组合：SIB1的资源、PRACH资源、Paging消息的资源，以及MBSFN资源。
其中，所述预设的带宽范围为所述终端设备预设的，且***带宽包含于所述预设的带宽范围内，这样，可以保证所述终端设备可以在基站广播所述MIB时，可以检索到所述MIB。
可选的，所述MIB包含4bits，其中，所述第一带宽指示信息占用1bit或2bits或3bits，所述无线帧配置域占用1bit。
由于所述第一带宽指示信息占用1bit-3bits，所以当所述第一带宽指示信息占用1bit时，所述MIB中还包含2bits保留信息；当所述第一带宽指示信息占用2bits时，所述MIB中还包含1bit保留信息；当所述第一带宽指示信息占用3bits时，所述MIB中不包含保留信息。
根据图2所示的实施例对所述第一带宽指示信息的描述可知，在本发明实施例中，在***可用带宽划分为多个范围后，所述基站以及所述终端设备中均维护有所述第一带宽指示信息所有的取值以及每个取值对应的***带宽所在的范围。这样，所述基站发送包含所述第一带宽指示信息的所述MIB时，所述终端设备获得所述MIB，即可确定***带宽所在的第一范围。通过上述方法，本发明实施例可以尽量降低信息开销，并提高了终端设备通过MIB获得的***带宽的准确度。
在本发明实施例中，通过所述无线帧配置域表示发送所述MIB的无线帧中是否配置有以下至少一项或组合：SIB1的资源、PRACH资源、Paging消息的资源，以及MBSFN资源，因此，后续终端设备在一个无线帧中检索到所述MIB后，可以直接根据所述无线帧配置域，确定所述无线帧的配置信息，根据所述无线帧的配置信息，判定是否执行以下操作：在所述无线帧中检索SIB1、在所述无线帧中检索Paging消息、在所述无线帧中检索MBSFN资源以及通过所述无线帧发送PRACH消息，进一步降低了所述基站传输所述MIB信息的开销，同时所述终端设备可以通过根据所述无线帧配置域获得的无线帧的配置信息判定是否执行上述四项操作中相应的操作，避免了在所述无线帧未配置上述四项内容中部分内容时，所述终端设备确执行未配置的内容对应的操作，从而降低了所述终端设备的功耗。
综上所述，本发明实施例中基站发送的所述MIB包含4bits的内容，相对于传统的MIB包含24bits的内容，本发明实施例基站发送所述MIB，降低了基站传输所述MIB的信息开销，从而降低了基站的功耗。
步骤302：所述终端设备在一无线帧中检索到所述MIB时，根据所述MIB中包含的所述第一带宽指示信息确定***带宽所在的第一范围；以及根据所述MIB中包含的所述无线帧配置域，获取所述无线帧的配置信息。
在步骤302中，所述终端设备在检索到所述MIB时，由于所述终端设备中均维护有所述第一带宽指示信息所有的取值以及每个取值对应的***带宽所在的范围，因此，所述终端设备可以根据所述MIB中包含的所述第一带宽指示信息确定***带宽所述在的第一范围。所述第一带宽指示信息指示的所述第一范围内包括预设的至少一个***可用带 宽，且所述至少一个***可用带宽中包含当前的所述***带宽。
由于所述无线帧配置域表示发送所述MIB的无线帧中是否配置有以下至少一项或组合：SIB1的资源、PRACH资源、Paging消息的资源，以及MBSFN资源。具体包括以下情况或组合：
第一种情况：所述无线帧配置域中表示所述无线帧中是否配置有SIB1的资源；
第二种情况：所述无线帧配置域表示所述无线帧中是否配置有Paging消息的资源；
第三种情况：所述无线帧配置域表示所述无线帧中是否配置有MBSFN资源；
第四种情况：所述无线帧配置域表示所述无线帧中是否配置有PRACH资源。
在第一种情况下：
当所述无线帧配置域表示所述无线帧中配置有SIB1的资源时，所述无线帧的配置信息为设定第一资源集合中的资源用于发送SIB1；在所述终端设备获取所述无线帧的配置信息后，所述方法还包括：所述终端设备在所述无线帧的所述第一资源集合中的所有资源中检索SIB1，并获取在所述第一资源集合中的资源中的所述SIB1；
当所述无线帧配置域表示所述无线帧中未配置有SIB1的资源时，所述无线帧的配置信息为所述无线帧不用于发送SIB1，所述终端设备获取所述无线帧的配置信息后，所述方法还包括：所述终端设备不在所述无线帧中检索SIB1。
可选的，所述SIB1中包含所述无线帧的帧号信息、第二带宽指示信息，其中，所述第二带宽指示信息用于指示在所述第一范围内的***带宽；
在所述终端设备获取所述SIB1之后，还包括：
所述终端设备根据所述第二带宽指示信息，在所述第一范围内确定***带宽；
所述终端设备根据所述无线帧的帧号信息，确定所述无线帧的帧号。
其中，所述SIB1中还包含传统的信息，例如小区接入相关信息、小区选择信息、***消息窗口长度、最大发送功率，***信息改变标志位、***消息调度列表、TDD配置信息以及频率带宽指示等终端设备小区驻留所需信息以及对其他***信息块的调度信息，保证所述终端设备可以根据所述SIB1中驻留在小区中，进入连接状态，以及接收其他***信息块。
由于所述MIB中未包含发送所述无线帧的帧号信息，因此，所述终端设备无法根据检索到的所述MIB获得所述无线帧的帧号。且所述无线帧的帧号信息用于通知所述终端设备***的时间信息，使所述终端设备可以进行小区同步。所述SIB1中包含所述无线帧的帧号信息，可以使所述终端设备继续可以获得所述无线帧的帧号，从而进行小区同步操作，避免由于降低所述MIB的信息开销，导致所述无线帧的帧号信息无法发送至所述终端设备的问题。
由于所述MIB中包含的第一带宽指示信息指示了***带宽所在的第一范围，因此，所述终端设备在接收到所述MIB后，只能确定一个比较大的***带宽所在的所述第一范围，而无法精确地确定***带宽。尤其是当***可用带宽范围较大时，仅将***可用带宽范围进行一次划分，划分的每个范围都比较大，因此，需要对第一次划分的每个范围内确定***带宽，即首先对***可用带宽进行粗粒度的一次划分，划分为2-8个大范围，然后，对每个粗粒度的范围进行细粒度的二次确认。
所述SIB1中包含的所述第二带宽指示信息指示在所述第一范围内的具体的***带宽。这样，所述终端设备在接收到所述SIB1以后，可以根据所述第二带宽指示信息，精 确地确定***带宽，以使所述终端设备后续可以在确定的***带宽内与所述基站进行数据交互。
在第二种情况下：
当所述无线帧配置域表示所述无线帧中配置有Paging消息的资源时，所述无线帧的配置信息为设定第二资源集合中的资源用于发送Paging消息；在所述终端设备获取所述无线帧的配置信息后，所述方法还包括：所述终端设备在所述无线帧的所述第二资源集合中的所有资源中检索Paging消息，并获取在所述第二资源集合中的资源中的Paging消息；
当所述无线帧配置域表示所述无线帧中未配置有Paging消息的资源时，所述无线帧的配置信息为所述无线帧不用于发送Paging消息；在所述终端设备获取所述无线帧的配置信息后，所述方法还包括：所述终端设备不在所述无线帧中检索Paging消息。
在第三种情况下：

在第四种情况下：
当所述无线帧配置域表示所述无线帧中配置有PRACH资源时，所述无线帧的配置信息为设定第四资源集合中的资源用于设置为PRACH资源，所述PRACH资源用于所述终端设备发送PRACH消息；在所述终端设备获取所述无线帧的配置信息后，所述方法还包括：所述终端设备通过所述无线帧中所述第四资源集合中的资源向基站发送所述PRACH消息；
