非竞争随机接入资源配置方法、终端设备和网络设备

本申请主张在2018年4月4日在中国提交的中国专利申请No.201810301951.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，更具体地涉及一种非竞争随机接入资源配置方法、终端设备和网络设备。
背景技术
在长期演进(Long Term Evolution，LTE)系统中，对于非竞争随机接入过程，网络设备向终端设备发送携带前导索引(preamble index)和物理随机接入控制信道(Physical Random Access Channel，PRACH)掩码索引(mask index)的信息，以指示终端设备在所述PRACH mask index所指示的PRACH资源上发送所述preamble index对应的前导码(preamble)，并且网络设备常通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)或无线资源控制(Radio Resource Control，RRC)信令向终端设备发送上述信息。
在新无线(New Radio，NR)系统中，网络设备可以在一个时间点(time instance)上配置多个频分复用(Frequency Division Multiplex，FDM)的物理随机接入信道传输机会(PRACH transmission occasion，也可以写成PRACH occasion)。并且，在一个PRACH资源配置周期内，可以存在多个时间点。其中，时间点，可以是传输一个PRACH资源所需的时长，也可以说成是用于传输PRACH资源的时域资源位置。为了便于描述，将PRACH transmission occasion简称为RO。
此外，在NR中，RO资源可能与同步信号块(Synchronization signal block，SSB，或者也可以称为Synchronization signal/Physical broadcast signal block,SS/PBCH block)之间可能存在关联关系，例如，一个RO资源上可能关联{1/8,1/4,1/2,1,2,4,8,16}等多个SSB。对于非竞争随机接入过程，RO资源也可能 与信道状态参考信号(Channel State Information-Reference Signals，CSI-RS)存在关联关系。并且，当一个PRACH资源配置周期内配置的RO资源总数大于等于完成两次SSB-RO(或CSI-RS-RO)映射所需的RO资源数目时，可以在这些RO资源上重复SSB-RO(或CSI-RS-RO)映射。为了便于理解，在这里将与RO资源关联的SSB或CSI-RS称为RO资源的关联对象。
目前，在一个PRACH资源配置周期内，网络设备需要较多的比特数才能能够指示清楚每个RO资源。例如，在FR1(Frequency Range1)的频分双工(Frequency Division Duplex，FDD)制式下，如果一个PRACH资源配置周期内存在140个时间点，每一时间点上对应存在8个RO资源，则需要13个比特来指示140*8个RO资源，需要3个比特来指示RO资源的编号，以及需要8个比特来指示PRACH mask index，才能指示清楚每个RO资源。在FR2(Frequency Range2)的时分双工(Time Division Duplex(ing)，TDD)制式下，如果一个PRACH资源配置周期内存在560个时间点，每一时间点上对应存在8个RO资源，则需要13个比特来指示560*8个RO资源，其中3个比特来指示RO资源的编号，以及需要10个比特来指示PRACH mask index，才能指示清楚每个RO资源。
然而，PDCCH的承载能力有限，可能无法提供足够的比特以对每个RO资源做出清楚的指示；另一方面，当完成一次完整的SSB-RO(或CSI-RS-RO)映射所需的RO资源较少时，若分配的时间点较多，此时可能在这些时间点进行了几十甚至上百次的重复映射，会造成只有很少的资源可以用于其他上行信号，这种配置方式对上行控制和数据的传输影响很大，因此这样配置的可能性很小，而如果专门为了这种配置而引入十几比特的PRACH资源指示信息，会导致比特的浪费。因此，需要设计一种通过较少的比特数(例如4bit)灵活地指示可用的PRACH资源。

下面先结合附图1至4，对应用于网络设备的非竞争随机接入资源配置方法进行说明。
图1示出了根据本申请一个实施例的非竞争随机接入资源配置方法，应用于网络设备。如图1所示，该方法可以包括如下步骤：
步骤101、基于预设映射关系，向终端设备发送目标资源指示信息；其中，所述目标资源指示信息用于确定物理随机接入信道传输机会(PRACH transmission occasion，RO)资源，所述目标资源指示信息包括：物理随机接入控制信道PRACH掩码索引(mask index)和RO资源索引(RO index)中的至少一个，所述预设映射关系为所述目标资源指示信息的取值范围与RO资源的对应关系。
预设映射关系，可以是所述网络设备预先确定的，也可以是协议规定的，且上述预设映射关系与RO资源分组有关，在一个例子中，上述预设映射关系具体可以是网络设备基于RO资源分组确定的，在其他例子中，上述预设关系还可以网络设备基于RO资源分组和其他参考因素的结合确定的，其中其他参考因素可以包括：频段(例如FR1或FR2)、制式(例如FDD或TDD)，等等。
目标资源指示信息，可以是网络设备需要发送给终端设备的RO资源的指示信息。
对于目标资源指示信息的取值范围，举例来说，在目标资源指示信息只包括PRACH掩码索引的情况下，目标资源指示信息的取值范围具体可以是 PRACH掩码索引编号；在目标资源指示信息只包括RO资源索引的情况下，目标资源指示信息的取值范围具体可以是RO资源索引编号；在目标资源指示信息同时包括PRACH掩码索引和RO资源索引的情况下，目标资源指示信息的取值范围具体可以是PRACH掩码索引编号和RO资源索引编号组成的二元组。
可以理解，目标资源指示信息中包含的PRACH掩码索引或RO资源索引的数量可以是一个，也可以是多个。
对于RO资源分组，具体可以是基于预设参数对预设时间间隔内配置的RO资源进行分组得到的；其中，所述预设参数包括RO资源标识、RO资源的时间位置、RO资源的频域位置、RO资源的关联对象类型以及关联组中的一种，所述关联对象类型包括同步信号块SSB或信道状态参考信号CSI-RS，所述关联组为完成RO资源与关联对象的一次完整映射所需要的RO资源组成的集合。
其中，预设时间间隔，可以是网络设备配置RO资源的配置周期，由于RO资源是PRACH资源，因此，RO资源的配置周期也可以理解为是网络设备配置PRACH资源的配置周期。或者，预设时间间隔，可以是同步周期，所谓同步周期，是完成RO与关联对象的一次完整映射所需要的最短时间，通常情况下，该最短时间是上述配置周期的1倍、2倍或4倍。
下面结合详细的例子说明基于各预设参数，对预设时间间隔内配置的RO资源进行分组的情况。
在以RO资源标识对RO资源进行分组的例子中，RO资源标识，可以理解为是预设时间间隔内网络设备配置的每一RO资源的标识，且不同RO资源的标识不同。这样，当所述预设参数为RO资源标识时，RO资源分组的数量等于所述预设时间间隔内配置的RO资源的数量。例如，假设在一个PRACH配置周期内，网络设备配置了10个RO资源，则对应存在10个不同的RO资源标识，相应的将RO资源分成了10组，每组中包含一个RO资源。
在以RO资源的时间位置对RO资源进行分组的例子中，时间位置也可以理解为是时域机会或时间点(time instance)，并且具体可以将具有相同时间位置的RO资源分在同一组中，例如将均位于符号(symbol)n至符号n+N 的RO资源分在同一组中，其中N为当前配置的前导格式(format)下，一个RO资源占据的符号数。
在以RO资源的频域位置对RO资源进行分组的例子中，频域位置可以是一个频段或一个具体的频率，并且具体可以将具有相同频域位置的RO资源分在同一组中。
为了更清楚地理解以RO资源的关联对象类型对RO资源进行分组的例子，下面以关联对象为SSB为例，对RO资源与关联对象的关联进行说明。在NR中，RO资源和网络设备实际发送的SSB之间可能存在关联关系，且一个RO资源上可能关联多个SSB，具体来说，一个RO资源可以关联的SSB数目可以是：{1/8,1/4,1/2,1,2,4,8,16}。例如，如图2所示，假设一个RO资源关联1/8个SSB，一个时间点上有4个RO资源在进行FDM，共有3个SSB，且这3个SSB编号为1-3，具体表示为：SSB1、SSB2和SSB3(在实际应用中也可以用0-2编号，并具体表示为：SSB0、SSB1和SSB2)。在图2中，T表示一个PRACH资源配置周期，一个格子代表一个RO资源，具有不同填充图案的格子代表与不同的SSB关联的RO资源，格子的行数代表一个时间点上的RO资源数量，格子的列数代表时间点数。其中，网络设备实际发送的SSB的数量小于或等于网络设备可发送的SSB的数量。
在此基础上，在以RO资源的关联对象类型对RO资源进行分组的例子中，可以将具有相同关联对象类型的RO资源分在同一组，且同一组中的每一RO资源关联的关联对象可以是一个也可以是多个。例如，将关联一个SSB且都关联SSB1的RO资源分在同一组；再如，将关联两个SSB且都关联SSB2和SSB3的RO资源分在同一组中，以此类推。
为了更清楚地理解以关联组对RO资源进行分组的例子，下面也以关联对象为SSB为例，对关联组进行说明。如上文所述，关联组为完成RO资源与关联对象的一次完整映射所需要的RO资源组成的集合。具体来说，当网络设备在一个PRACH资源配置周期内配置的RO资源总数大于或等于完成两次完整的SSB-RO(或CSI-RS-RO)映射所需的RO资源数目时，可以在配置的这些RO资源上重复SSB-RO(或CSI-RS-RO)映射。
如图3所示，假设一个RO资源关联1/8个SSB，共有3个SSB，这3 个SSB的编号为1-3，分别对应图3中的SSB1、SSB2和SSB3，则完成一次完整的SSB-RO映射需要8*3＝24个RO资源，一个PRACH资源配置周期T内有12个时间点，一个时间点上有4个RO资源进行FDM，则一个PRACH资源配置周期T内共有12*4＝48个RO资源，进而可以在该PRACH资源配置周期内重复两次完整的SSB-RO映射。
再比如，如果一个PRACH资源配置周期T内配置的RO资源总数为72，则可以在该配置周期内重复三次完整的SSB-RO映射，如果一个PRACH资源配置周期T内配置的RO资源总数更多，则可以重复更多次完整的SSB-RO映射，以此类推。
在此基础上，在以关联组对RO资源进行分组的例子中，可以将具有相同关联组的RO资源分在同一组。
为了对上文中述及的RO资源索引和RO资源标识所表示的含义做出区分，下面结合图4对RO资源索引所表示含义进行说明，关于RO资源标识的含义请参阅上文。
如本申请背景技术中所述，在LTE中，对于非竞争随机接入过程，网络设备常通过PSCCH或RRC向终端设备发送携带前导索引(preamble index)和PRACH掩码索引(mask index)的信息，以指示终端设备在所述PRACH掩码索引所指示的PRACH资源上发送所述preamble index对应的前导码。并且，在NR中，允许在触发非竞争随机接入过程的PDCCH中携带3比特的RO index和6比特的SSB index。其中，SSB index是SSB索引，RO index是与该SSB index关联的RO资源索引，例如，假设共有3个SSB，每个SSB关联8个RO资源，那么如果SSB index＝3，RO index＝2，则表示与SSB3关联的RO2。
请参阅图4，关于RO2可以有两种理解：一是指当前时间点上FDM的RO资源中频域编号为的RO，例如图4中数字2、6所在的格子；二是指当前SSB-RO映射中与SSB3关联的RO资源中索引编号为2的RO资源，例如图4中数字2所在的格子。
示例性地，步骤101中的预设映射关系可以包括但不限于下列14条对应关系中的一个或多个：
(1)如果目标资源指示信息的取值范围位于第一预设区间，对应的RO资源为：所述预设时间间隔内配置的所有RO资源。
(2)如果目标资源指示信息的取值范围位于第二预设区间，对应的RO资源为：编号为奇数的RO资源分组中，与预设关联对象关联的RO资源。
例如，在以关联组对RO资源分组的情况下，如果目标资源指示信息中的PRACH掩码索引的取值为1，对应的RO资源为：每第奇数个关联组中，与预设关联对象关联的RO资源。下文会对预设关联对象统一进行说明，此处按下不表。
(3)如果目标资源指示信息的取值范围位于第三预设区间，对应的RO资源为：编号为偶数的RO资源分组中，与预设关联对象关联的RO资源。
例如，在以关联组对RO资源分组的情况下，如果目标资源指示信息中的PRACH掩码索引的取值为2，对应的RO资源为：每第偶数个关联组中，与预设关联对象关联的RO资源。
(4)如果目标资源指示信息的取值范围位于第四预设区间，对应的RO资源为：编号为奇数的RO资源分组中，与预设关联对象关联的索引编号为奇数的RO资源；以及编号为偶数的RO资源分组中，与预设关联对象关联的索引编号为偶数的RO资源。
例如，在以关联组对RO资源分组的情况下，如果目标资源指示信息中的PRACH掩码索引的取值为3，对应的RO资源为：第奇数个关联组中，与预设关联对象关联的RO资源中索引编号为奇数的RO资源，以及第偶数个关联组中，与预设关联对象关联的RO资源中索引编号为偶数的RO资源。
(5)如果目标资源指示信息的取值范围位于第五预设区间，对应的RO资源为：所有RO资源分组中的第i个子分组中，与预设关联对象关联的所有RO资源，其中，i是根据所述目标资源指示信息的具体取值确定的，所述子分组是对所有RO资源分组按序均分得到的，i为大于零且小于或等于所述子分组的总数的整数。
例如，在以关联组对RO资源分组的情况下，如果目标资源指示信息中的PRACH掩码索引的取值为1，对应的RO资源为：前二分之一个关联组中，与预设关联对象关联的RO资源；或者，如果目标资源指示信息中的PRACH 掩码索引的取值为2，对应的RO资源为：后二分之一个关联组中，与预设关联对象关联的RO资源。也即将所有RO资源分组按序均分成前后两个子分组(i可以取{1,2})，该子分组可以称为1/2子分组，前二分之一个关联组即为第1个(i＝1)1/2子分组，后二分之一个关联组即为第2个(i＝2)1/2子分组。
再如，如果将所有RO资源分组按序均分成四个子分组(i可以取{1,2,3,4})，该子分组可以称为1/4子分组，则存在：第1个(i＝1)1/4子分组、第2个(i＝2)1/4子分组、第3个(i＝3)1/4子分组和第4个(i＝4)1/4子分组。此时，如果目标资源指示信息中的PRACH掩码索引的取值为1，对应的RO资源为：第一个四分之一关联组中，与预设关联对象关联的RO资源；或者，如果目标资源指示信息中的PRACH掩码索引的取值为2，对应的RO资源为：第二个四分之一关联组中，与预设关联对象关联的RO资源。
(6)如果目标资源指示信息的取值范围位于第六预设区间，对应的RO资源为：所有RO资源分组中，与预设关联对象关联的所有RO资源中的第j个子分组中的RO资源，其中，j是根据所述目标资源指示信息的具体取值确定的，所述子分组是对所述与预设关联对象关联的所有RO资源按序均分得到的，j为大于零且小于或等于所述子分组的总数的整数。
例如，将所述与预设关联对象关联的所有RO资源按序均分成前后两个子分组(j可以取{1,2})，该子分组可以称为1/2子分组，每个关联组的前二分之一即为第1个(i＝1)1/2子分组，每个关联组的后二分之一即为第2个(i＝2)1/2子分组。
再如，如果将所述与预设关联对象关联的所有RO资源按序均分成四个子分组(j可以取{1,2,3,4})，该子分组可以称为1/4子分组，则每个关联组的首个四分之一即为第1个(i＝1)1/4子分组、每个关联组的第二个四分之一即为第2个(i＝2)1/4子分组、每个关联组的第三个四分之一即为第3个(i＝3)1/4子分组，以及每个关联组的最后一个四分之一即为第4个(i＝4)1/4子分组。
(7)如果目标资源指示信息的取值范围位于第七预设区间，对应的RO资源为：从预设编号的RO资源分组开始的连续预设数量个RO资源分组中， 与预设关联对象关联的RO资源。
例如，在以关联组对RO资源分组的情况下，如果目标资源指示信息中的PRACH掩码索引的取值为7，对应的RO资源可以为：从第X个关联组开始连续Y个分组中，与预设关联对象关联的RO资源。
(8)如果目标资源指示信息的取值范围位于第八预设区间，对应的RO资源为：预设编号的RO资源分组中，与预设关联对象关联的所有RO资源，其中，所述预设编号是根据所述目标资源指示信息的具体取值确定的。
例如，在以关联组对RO资源分组的情况下，如果目标资源指示信息中的PRACH掩码索引的取值为8，对应的RO资源可以为：第9个RO资源分组中，与预设关联对象关联的所有RO资源。
(9)如果目标资源指示信息的取值范围位于第九预设区间，对应的RO资源为：所有RO资源分组中，与预设关联对象关联的索引编号为预设索引编号的RO资源。
其中，预设索引编号，可以基于所述PRACH掩码索引的指定比特位的值和其余比特位指示的值来确定。
例如，在以关联组对RO资源分组的情况下，假设指定比特位为最高比特位，如果目标资源指示信息中的PRACH掩码索引的取值为9，对应的二进制数为111，该PRACH掩码索引的最高比特位的值为1，其余比特位指示的值为3，那么可以将其余比特位指示的值确定为预设索引编号，则对应的RO资源可以为：所有RO资源分组中，与预设关联对象关联的索引编号为3的RO资源(也即RO 3)。
(10)如果目标资源指示信息的取值范围位于第十预设区间，对应的RO资源为：编号为奇数的RO资源分组中，与预设关联对象关联的索引编号为预设索引编号的RO资源。
其中，预设索引编号的确定方法可以与第9条对应关系中类似，下面不再赘述。
(11)如果目标资源指示信息的取值范围位于第十一预设区间，对应的RO资源为：编号为偶数的RO资源分组中，与预设关联对象关联的索引编号为预设索引编号的RO资源。
(12)如果目标资源指示信息的取值范围位于第十二预设区间，对应的RO资源为：所有RO资源分组中的第k个子分组中，与预设关联对象关联的索引编号为预设索引编号的RO资源，其中，k是根据所述目标资源指示信息的具体取值确定的，所述子分组是对所有资源分组按序均分得到的，k为大于零且小于或等于所述子分组的总数的整数。
在本条对应关系中，子分组的划分以及k的取值的确定与第(5)条中类似，此处不再赘述。
(13)如果目标资源指示信息的取值范围位于第十三预设区间，对应的RO资源为：预设编号的RO资源分组中，与预设关联对象关联的索引编号为预设索引编号的RO资源，其中，所述预设编号是根据所述目标资源指示信息的具体取值确定的。
(14)如果目标资源指示信息的取值范围位于第十四预设区间，对应的RO资源为：从预设编号的RO资源分组开始的连续预设数量个RO资源分组中，与预设关联对象关联的索引编号为预设索引编号的RO资源。
需要说明的是，上述14条对应关系并非预设映射关系中包括的对应关系的穷举，本领域技术人员可以基于本公开实施例的技术构思延伸出更多的对应关系，或者说延伸出目标资源指示信息的不同取值所代表的更多含义。
还需要说明的是，上文中的第一预设区间至第十四预设区间中包含的取值可以是一个，也可以是多个。
可以理解，假设实际应用中确定出的目标资源指示信息的取值范围与RO资源的对应关系不大于16条，则网络设备通过4比特就能实现RO资源的指示，从而降低了用于指示非竞争接入过程的PRACH资源的比特开销。
在具体实现时，上述步骤101具体可以包括：通过物理下行控制信道PDCCH或无线资源控制RRC，向终端设备发送目标资源指示信息。
在此基础上，在一个例子中，如果所述PDCCH或所述RRC中还携带有一个或多个关联对象索引编号，上述14条对应关系中的预设关联对象可以为，所述一个或多个关联对象索引编号对应的关联对象。
例如，假设PDCCH或RRC还携带了SSB指示信息，且该SSB指示信息中包括一个或一组与RO资源相关联的SSB，在本公开实施例中可以将SSB 指示信息中指示的SSB记为SSB列表(ssb-ResourceList)。这样，上述14条对应关系中的预设关联对象可以为SSB列表中的关联对象。
在另一个例子中，上述14条对应关系中的预设关联对象还可以包括所述网络设备发送的(可以是网络设备实际发送的)多个关联对象，这多个关联对象可以网络设备发送的所有关联对象，也可以是网络设备发送的部分关联对象。在该例子中具体可以存在两种情况，一种是，所述PDCCH或所述RRC中没有携带关联对象索引编号，可以直接将网络设备实际发送的多个关联对象作为预设关联对象；另一种是，虽然所述PDCCH或所述RRC中携带了关联对象索引编号，但是所携带的关联对象索引编号是无效的，从而将网络设备实际发送的多个关联对象作为预设关联对象。
此外，如上文所述，如果所述目标资源指示信息包括PRACH掩码索引且不包括RO资源索引，可以基于所述PRACH掩码索引的指定比特位的值和其余比特位指示的值，确定上述14条对应关系中所述的预设索引编号。其中，指定比特位可以是PRACH掩码索引的任意一个或多个比特位，例如最高比特位，或最低比特位，或者最高比特位和次高比特位。
具体来说，在指定比特位为最高比特位的情况下，如果所述PRACH掩码索引的最高比特位为第一预设值，所述预设索引编号为所述PRACH掩码索引的其余比特位指示的值；如果所述PRACH掩码索引的最高比特位为第二预设值，所述预设索引编号为所述PRACH掩码索引的其余比特位指示的值以外的值；其中，所述第一预设值和所述第二预设值不同。
例如，如果PRACH掩码索引的最高比特位为指示为0(第一预设值＝0)，PRACH掩码索引除了最高比特位之外的其他比特位的值为N，此时RO资源的预设索引编号为N。且PRACH掩码索引结合SSB索引表示的是与SSB列表中的关联对象关联的RO资源中索引编号为N的RO资源。如果PRACH掩码索引最高比特位为指示为1(第二预设值＝1)，PRACH掩码索引除了最高比特位之外的其他比特位的值为N，此时PRACH掩码索引不指示RO资源中索引编号为N的RO资源，而是其他RO资源。
再有，在本公开实施例中，所述预设时间间隔内配置的RO资源可以包括：所述预设时间间隔内配置的所有RO资源中的任意RO资源，或所述预 设时间间隔内配置的所有RO资源中的有效RO资源。
其中，在不同的应用场景下，有效RO资源的含义不同。在FR1下，RO资源一般在剩余最小系统信息(Remaining Minimum System Information，RMSI)配置的半静态DL/UL配置中的上行部分传输，通常认为RO资源不会和下行传输冲突，也即一般认为FR1下的RO资源均是有效的。在FR2下，RO资源一般是在RMSI配置的半静态DL/UL配置中的上行部分和灵活(flexible)部分传输，且在一个随机接入信道(Random Access Channel，RACH)时隙内，有效的RO资源不会和SSB冲突，也不会出现在SSB前面，终端设备不期望在任何有效的RO上接收到下行信号，也即一般认为不会和SSB冲突、不会出现在SSB前面以及不会接收到下行信号的RO资源是有效的。
本公开实施例提供的非竞争随机接入资源配置方法，由于网络设备向终端设备发送内容较少的目标资源指示信息就可以实现RO资源的指示，因此可以降低用于指示非竞争接入过程的RO资源所需的比特开销。此外，这种通过目标资源指示信息的取值范围与RO资源的对应关系，确定物理随机接入信道传输机会RO资源的方式较为灵活，从而提升了网络设备配置RO资源的灵活性。
以上对应用于网络设备的非竞争随机接入资源配置方法进行了总的说明，下面结合具体的例子对预设映射关系进行说明。
在第一个例子中，针对不同的频段(FR1或FR2)、不同制式(FFD或TDD)分别设计目标资源指示信息(也即分频段、分制式进行设计)，且目标资源指示信息包括：PRACH掩码索引和RO资源索引，并通过关联组对RO资源进行分组，以及通过PDCCH或RRC向终端设备发送目标资源指示信息。
假设PDCCH或RRC中还携带了SSB指示信息，且该SSB指示信息中包括一个或多个与RO资源相关联的SSB(例如，SSB指示信息指示了一个和RO资源相关联的SSB，或者SSB指示信息指示了一组和RO资源相关联的SSB)，并记为SSB列表(ssb-ResourceList)。假设RO资源索引的取值为N，与SSBM关联的RO资源中索引编号为N的RO资源，记作RO N。并假设在FDD&FR1、TDD&FR1和TDD&FR2下，基站在一个PRACH资源配置周期中配置的关联组的数目分别不会超过N1、N2和N3，且N1>N3>N2。
在此基础上，可以确定出如表1所示的预设映射关系。

在第二个例子中，针对不同的频段(FR1或FR2)、不同制式(FFD或TDD)设计相同的目标资源指示信息(也即不分频段、不分制式统一进行设计)，且目标资源指示信息包括：PRACH掩码索引和RO资源索引，并通过关联组对RO资源进行分组，以及通过PDCCH或RRC向终端设备发送目标资源指示信息。
假设PDCCH或RRC中还携带了SSB指示信息，且该SSB指示信息中包括一个或多个与RO资源相关联的SSB(例如，SSB指示信息指示了一个和RO资源相关联的SSB，或者SSB指示信息指示了一组和RO资源相关联的SSB)，并记为SSB列表(ssb-ResourceList)。假设RO资源索引的取值为N，与SSBM关联的RO资源中索引编号为N的RO资源，记作RO N。并假设在基站在一个PRACH资源配置周期中配置的关联组的数目不会超过X。

假设PDCCH或RRC中还携带了SSB指示信息，且该SSB指示信息中包括一个或多个与RO资源相关联的SSB(例如，SSB指示信息指示了一个和RO资源相关联的SSB，或者SSB指示信息指示了一组和RO资源相关联的SSB)，并记为SSB列表(ssb-ResourceList)。在该例子中，既可以将SSB列表中的SSB确定为预设关联对象，也可以将网络设备实际发送的所有SSB作为预设关联对象。
如果PRACH掩码索引的最高比特位为指示为0(第一预设值＝0)，PRACH掩码索引除了最高比特位之外的其他比特位的值为N，此时RO资源的预设索引编号为N。且PRACH掩码索引结合SSB索引表示的是与SSB列表中的关联对象关联的RO资源中索引编号为N的RO资源。
如果PRACH掩码索引最高比特位为指示为1(第二预设值＝1)，PRACH掩码索引除了最高比特位之外的其他比特位的值为N，此时PRACH掩码索引不指示RO资源中索引编号为N的RO资源，而是其他RO资源。

假设PDCCH或RRC中还携带了SSB指示信息，且该SSB指示信息中包括一个或多个与RO资源相关联的SSB(例如，SSB指示信息指示了一个和RO资源相关联的SSB，或者SSB指示信息指示了一组和RO资源相关联的SSB)，并记为SSB列表(ssb-ResourceList)。在该例子中，既可以将SSB列表中的SSB确定为预设关联对象，也可以将网络设备实际发送的所有SSB作为预设关联对象。
在此基础上，可以确定出同样如表3所示的预设映射关系。
在第五个例子中，针对不同的频段(FR1或FR2)、不同制式(FFD或TDD)分别设计目标资源指示信息(也即分频段、分制式进行设计)，目标资源指示信息只包括PRACH掩码索引且不包括RO资源索引，并通过关联组对RO资源进行分组，以及通过PDCCH或RRC向终端设备发送目标资源指示信息。
