具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
在对本申请实施例进行说明之前，对相关内容进行简要说明。
NR系统可支持增强移动带宽(Enhanced Mobile Broadband，eMBB)业务，以满足高速率、高频谱效率以及大带宽的需要。在实际应用中，除了eMBB业务，还存在多种不同的业务类型，例如传感器网络、视频监控以及可穿戴等，这些类型的业务在速率、带宽、功耗和成本等方面与eMBB业务有着不同的需求。支持这些业务的终端设备相比支持eMBB的终端设备的能力是降低的，如支持的带宽减小、处理时间放松以及天线数减少等。因此，需要针对这些业务和相应的低能力终端设备对NR系统进行优化，优化后的的系统称为NR-light系统。在LTE技术中，已经有了类似的系统设计用于支持大连接数、低功耗、低成本的终端，如机器类通信(Machine Type Communication，MTC)和窄带宽物联网(Narrow Band Internet of Thing，NB-IoT)。在NR系统中，希望引入类似的技术用于使用NR技术更好的支持除eMBB业务之外的其他业务类型。支持这类业务的终端设备具有低复杂度、低成本和低能力的特点，称为降低能力终端设备。
降低能力终端设备相比传统的NR终端设备具有低复杂度和低成本的特点，例如减少的接收通道、降低支持的传输带宽等。目前NR终端设备至少需要支持2个接收通道，某些频段上的NR终端设备需要支持4个接收通道；每一个接收通道均包含接收天线，滤波器，功率放大器，模数采样器等元器件，因此，减少NR终端设备需要配备的射频通道数目将可显著降低终端成本。并且，传统NR终端设备需要支持较宽的传输带宽，如对于频率范围FR1，NR终端设备需要支持最大100MHz的带宽，对频率范围FR2，NR终端设备需要支持最大400MHz的带宽。为降低RedCap终端设备的成本以及降低RedCap终端设备的功耗，RedCap终端设备可以支持较小的传输带宽，对于频率范围FR1仅支持20MHz的传输带宽，对于频率范围FR2仅支持100MHz的传输带宽。
另外，降低能力终端设备还可能具有支持较低的峰值速率、支持较宽松的处理时延、以及较大的处理时延等特点。
针对NR系统中的同步信号块(SS/PBCH block，SSB)：在NR系统中，公共信道和信号，如同步信号和广播信道，需要通过多波束扫描的方式覆盖整个小区，便于小区内的终端设备接收。同步信号(Synchronization Signal，SS)的多波束发送是通过定义同步信号块突发集合(SS/PBCH burst set)实现的。一个SS/PBCH burst set包含一个或多个SS/PBCH block。一个SS/PBCH block用于承载一个波束的同步信号和广播信道。因此，一个SS/PBCH burst set可以包含小区内SS block number个波束的同步信号。SS block number的最大数目L与系统的频段有关：对于频率范围最大为3GHz，L为4，对于频域范围从3GHz到6GHz，L为8，对于频率范围从6GHz到52.6GHz，L为64。
一个SS/PBCH block(SSB)中包含一个符号的主同步信号(Primary Synchronization Signal，PSS)，一个符号的辅同步信号(Secondary Synchronization Signal，SSS)和两个符号的物理广播信道(Physical Broadcast Channel，PBCH)。其中，PBCH所占的时频资源中，包含用于解调PBCH的调参考信号(Demodulation Reference Signal，DMRS)。
SS/PBCH burst set内所有的SS/PBCH block在5ms的时间窗内发送，并以一定的周期重复发送，周期通过高层的参数SSB-timing进行配置，包括5ms，10ms，20ms，40ms，80ms，160ms等。对于终端设备来说，通过接收到的SS/PBCH block得到该SSB的索引(index)，SSB的index的取值范围为[0，L-1]，L为SSB所在频段对应的SSB的最大个数。SSB index对应该SSB在5ms时间窗内的相对位置，终端设备根据该信息和PBCH中承载的半帧指示，获取帧同步。其中，SS/PBCH block的index通过PBCH的DMRS或者PBCH承载的信息来指示。
小区内实际发送的SS/PBCH burst set内包含SSB的个数不一定是L个，可以根据实际需要发送，实际发送的SSB的index通过网络设备的指示信息ssb-PositionsInBurst进行指示。
针对随机接入(RACH)过程，在版本15(Rel-15)中，定义了用于终端设备随机接入配置的RACH资源，包括256种配置。小区使用的RACH资源配置信息在系统消息中指示给接入的终端设备。其中，每一种RACH资源配置包含了前导码格式(preamble format)、周期、无线帧偏移、无线帧内的子帧编号、子帧内的起始符号、子帧内RACH时隙的个数、RACH时隙内RACH时机的个数和PRACH时机持续时间。通过RACH资源配置可以确定PRACH资源的时域、频域和码域信息。如下表1所示，随机接入岁引号为86的随机接入配置包括前导码格式、随机接入时机所在的无线帧、子帧、起始符号以及时间长度等。
表1.频谱范围为FR2的随机接入配置和未匹配光谱
Figure PCTCN2021078767-appb-000001
前述对RACH资源的时域资源位置进行了说明；RACH资源的频域资源位置可通过高层信令RACH-ConfigGeneric中参数msg1-FrequencyStart和msg1-FDM指示；其中msg1-FrequencyStart用于确定确定随机接入时机0(RACH occasion 0)的资源块(Resource Block，RB)的起始位置相对于初始上行带宽部分(Bandwidth Partment，BWP)的频域起始位置(即BWP 0)的偏移，即确定RACH资源的频域起始位置。msg1-FDM的取值为{1,2,4,8}，用于确定频域RACH occasion(RO)的个数；而RACH占用的RB数由prach-RootSequenceIndex指示的preamble序列和ΔfRA共同确定(参见3GPP TS38.211表6.3.3.2-1)。其中，RB数是以物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)的RB数来表示的。随机接入的频域位置示意图，如图1所示，其中，msg1-FDM＝8，初始上行带宽部分包括8个随机接入时机。
对于终端设备来说，网络设备在系统消息指示的RACH资源配置的基础上，还指示了SSB与RACH资源的关联关系，使得终端设备可以根据检测到的SSB和该关联关系，确定其可以使用的RACH资源。通过ssb-PositionsInBurst指示的SSB中的每个SSB关联一个或者多个PRACH时机，每个SSB也关联多个基于竞争的前导码(Contention Based preambles)。即每个SSB index关联了系 统消息中指示的RACH资源配置中一部分特定的资源。
网络设备通过参数ssb-perRACH-Occasion配置N个SSB关联一个PRACH occasion，通过参数CB-PreamblesPerSSB配置每个SSB在每个有效的RACH occasion上基于竞争的前导码数。如果N<1，则一个SSB映射到1/N个连续有效的RACH occasion；例如：N＝1/4，则一个SSB映射到4个RACH occasion，且R个连续索引的preamble映射到SSB n，0<＝n<＝N-1，每个有效RACH occasion从preamble索引0开始。如果N>＝1，N个SBB映射到到一个RACH occation，一个SSB对应R个preamble，R个连续索引的preamble映射到SSB n，0<＝n<＝N-1，每个有效RACH occasion从preamble索引
Figure PCTCN2021078767-appb-000002
开始。例如：N＝2，
Figure PCTCN2021078767-appb-000003
则两个SSB映射1个RACH occasion，那么对于这两个SSB n，n＝0,1，当n＝0时，SSB 0的preamble索引从0开始；当n＝1时，在SSB 1的preamble索引从32开始。SSB 0上的preamble索引为0～31，SSB 1上的preamble索引为32～所配置竞争preamble-1。一个有效RACH occasion对应整个基于竞争的preamble数，此时一个有效PRACH occasion对应两个SSB，所以两个SSB各占部分preamble，与N<1的情况不同。其中
Figure PCTCN2021078767-appb-000004
由totalNumberOfRA-Preambles配置且是N的整数倍。相关的信令举例如下：
ssb-perRACH-OccasionAndCB-PreamblesPerSSB CHOICE{
oneFourth ENUMERATED{n4,n8,n12,n16,n20,n24,n28,n32,n36,n40,n44,n48,n52,n56,n60,n64},
该信令中，oneFourth表示一个SSB关联了4个RACH时机，n4表示一个SSB在一个PRACH时机关联了4个Contention Based preambles，以此类推。一个RACH时机里的Contention Based preambles的总数为CB-preambles-per-SSB*max(1,SSB-per-rach-occasion)。其中，CB-preambles-per-SSB为4，SSB-per-rach-occasion为1/4。
SSB到RACH occasion的映射应遵循如下顺序：1)在一个RACH occasion中preamble索引的顺序是递增的；2)频率复用RACH occasion的频率资源索引顺序是递增的；3)在RACH时隙内的时域复用RACH occasion的时域资源索引的顺序是递增的；4)RACH时隙索引的顺序是递增的。
举例来说，若SSB的数目为8，SSB对应的索引为0～7；msg1-FDM＝4，表示频域RACH occasion的个数为4；ssb-perRACH-Occasion＝1/4，则SSB与随机接入时机映射示意图，如下图2所示，1个SSB关联或映射到4个连续有效的RACH occasion。
相关技术中，终端设备在初始接入过程中，需要通过PBCH承载的主信息块(Master Information Block，MIB)信息中获得type0PDCCH的控制资源集CORESET#0和搜索空间search space#0信息，用于指示type0PDCCH的在频域上的RB和时域上的符号。CORESET#0信息指示下表中的其中一个index，根据index，得到CORESET#0的RB个数和符号数，以及相比SSB的RB偏移(offset)。对于频率范围FR1，在子载波间隔为15kHz情况下，CORESET#0的带宽可以配置为24、48、96个RB，对应5MHz、10MHz、20MHz的带宽。在30kHz子载波间隔下，CORESET#0配置的最大RB数为48，因此也不会超过20MHz的带宽。终端设备通过type0PDCCH接收承载SIB的物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)的调度信息，从而接收SIB1信息。对于频率范围FR1来说，RedCap终端设备在初始接入阶段可以支持20MHz带宽，大于或等于CORESET#0的带宽，因此可以成功接收type0PDCCH。同理，对于频率范围FR2来说，RedCap终端设备在初始接入阶段可以支持100MHz带宽，也大于或等于CORESET#0的带宽。
终端设备可以通过type0PDCCH接收承载SIB1的PDSCH的调度信息，从而接收SIB1信息。从SIB1信息中，终端设备可以获得初始下行BWP和初始上行BWP配置信息。在终端设备的随机接入过程中的信道的发送和接收过程中，可以在初始下行BWP和初始上行BWP上进行。在现有技术中，初始上行BWP配置的带宽允许超过CORESET#0的带宽。如果该小区支持RedCap终端设备的接入，并且沿用现有的初始上行BWP的配置，初始上行BWP配置的带宽可能会超过RedCap UE的带宽能力，造成RedCap终端设备在初始接入阶段无法正确接收和发送信道。由于RedCap终端设备支持的带宽可能小于初始上行带宽或初始下行带宽，因此RedCap终端设备带宽范围内的随机接入时机可能少于初始上行带宽或初始下行带宽范围内的随机接入时机；而初始上行带宽或初始下行带宽范围内的随机接入时机与网络配置的随机接入资源对应的全部SSB关联，导致RedCap终端设备带宽范围内的随机接入时机不能够关联到网络配置的随机接入资源对应的全部SSB；在该场景下，若RedCap终端设备检测到某个SSB满足要求，而该SSB却不能关联到RedCap终端设备带宽范围内的随机接入时机，则RedCap终端设备不能选择该SSB关联的随机接入资源，即现有技术未能为RedCap终端设备分配有效的随机接入资源。
在具体实施时，可通过下述方式解决上述问题：如RedCap终端设备进行调频，调频后的 RedCap终端设备支持的带宽包含需要的频域RO；或者为RedCap终端设备配置独立的initial UL BWP；或者网络设备配置的RACH资源或者initial UL BWP总是在RedCap终端设备的带宽范围内；或者为RedCap终端设备配置独立的RACH资源。
但是，上述解决方案对现有的RACH配置和initial UL BWP配置都有限制和影响，无法很好的为RedCap终端设备分配有效的随机接入资源。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、LTE系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、NR系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、无线局域网(wireless local area networks，WLAN)、无线保真(wireless fidelity，WiFi)、下一代通信系统或其他通信系统等。

本申请实施例提供的随机接入资源确定方法的一种可选处理流程，如图4所示，可以包括以下步骤：
步骤S201，终端设备确定第一随机接入时机集合。
在一些实施例中，终端设备根据所述终端设备支持的带宽和所述第二随机接入时机集合确定。其中，所述第二随机接入时机集合携带于网络设备向终端设备发送的随机接入时机配置信息中。若所述终端设备为降低能力终端设备，则所述终端设备支持的带宽内的随机接入时机构成第一随机接入时机集合，所述第一随机接入时机集合所述包括的随机接入时机不一定能完全覆盖第二随机接入时机结合内的全部随机接入时机，即第一随机接入时机集合可能与第二随机接入时机集合相同，第一随机接入时机集合内的随机接入时机与第二随机接入时机集合内的随机接入时机完全相同；第一随机接入时机集合也可能属于第二随机接入时机集合，即第一随机接入时机集合是第二随机接入时机集合的子集，所述第一随机接入时机集合所包括的随机接入时机是第二随机接入时机集合中的部分随机接入时机。
在一些实施例中，第一随机接入时机集合和第二随机接入时机集合的示意图，如图5所示，若终端设备根据网络设备发送的初始上行带宽部分(initial UL BWP)配置信息确定初始上行带宽为第二带宽，终端设备根据随机接入时机配置信息确定第二带宽内包括8个随机接入时机，8个随机接入时机构成第二随机接入时机集合，8个随机接入时机的索引为0-7；终端设备支持的带宽为第一带宽，第一带宽内包括4个随机接入时机，4个随机接入构成第一随机接入时机集合，4个随机接入时机的索引为2-5。
步骤S202，终端设备确定所述第一随机接入时机集合与SSB的关联关系。
在一些实施例中，所述SSB为与所述终端设备的随机接入资源关联的全部SSB，所述SSB通过网络设备发送的SSB集合指示信息确定。
在一些实施例中，所述第一随机接入时机集合与SSB的关联关系，可以是指所第一随机接入时机集合中的每个随机接入时机与SSB的关联关系，如N个SSB关联第一随机接入时机集合中的一 个随机接入时机，或者1个SSB关联第一随机接入时机集合中的X个随机接入时机；N和X均为正整数。可选地，第一随机接入时机集合与SSB的关联关系可通过ssb-perRACH-Occasion参数表示。
在一些实施例中，所述第二随机接入时机集合与所述SSB具有关联关系；具体的，网络设备可以通过向终端设备(如非降低能力终端设备)发送ssb-perRACH-Occasion参数来指示第二随机接入时机集合中的全部随机接入时机与终端设备的随机接入资源对应的全部SSB的关联关系。以图6为例，SSB与随机接入时机的一种可选关联关系示意图中，SSB的数目为8，8个SSB对应的索引为0-7；msg1-FDM＝8，表示频域上的随机接入时机的数量为8；ssb-perRACH-Occasion＝1，表示1个SSB关联第二随机接入时机集合中的一个随机接入时机。
在一种可选实施方式中，终端设备可以判断下述中的至少一项：所述第一随机接入时机集合是否包括所述第二随机接入时机集合内的全部随机接入时机，所述终端设备支持的带宽是否大于或等于初始上行带宽部分，以及所述第一随机接入时机集合是否已关联所述SSB；并根据判断结果确定第一随机接入时机集合与SSB的关联关系。
若所述第一随机接入时机集合包括所述第二随机接入时机集合内的全部随机接入时机，或者所述终端设备支持的带宽大于或等于初始上行带宽部分，或者所述第一随机接入时机集合已关联所述SSB，则基于所述第二随机接入时机集合确定所述第一随机接入时机集合与SSB的关联关系；由于第一随机接入时机集合已经覆盖所述第二随机接入时机集合内的全部随机接入时机，因此根据所述第二随机接入时机集合与所述SSB的关联关系便能确定所述第一随机接入时机集合与所述SSB的关联关系。其中，在所述第一随机接入时机集合包括所述第二随机接入时机集合内的全部随机接入时机，以及所述终端设备支持的带宽大于或等于初始上行带宽部分的场景下，第一随机接入时机集合内的随机接入时机已经覆盖第二随机接入时机集合内的全部随机接入时机；由于终端设备根据网络设备已经发送的ssb-perRACH-Occasion参数可以确定第二随机接入时机集合中的全部随机接入时机与终端设备的随机接入资源对应的全部SSB的关联关系，因此，可以将所述第二随机接入时机集合与所述SSB的关联关系确定为所述第一随机接入时机集合与SSB的关联关系。针对所述第一随机接入时机集合已关联所述SSB的场景，可以如图7所示，虽然终端设备支持的带宽内的第一随机接入时机集合不能够覆盖初始上行带宽内的第二随机接入时机集合内的全部随机接入时机，但是，第二随机接入时机集合与SSB关联时，第二随机接入时机集合所包括的第一随机接入时机集合已经与终端设备的随机接入资源对应的全部SSB(索引0-7的SSB)关联；在该场景下，可以根据所述第二随机接入时机集合与所述SSB的关联关系确定所述第一随机接入时机集合与SSB的关联关系，即终端设备基于第二随机接入时机集合确定所述第一随机接入时机集合与SSB的关联关系。
在另一种可选实施方式中，若所述第一随机接入时机集合包括所述第二随机接入时机集合内的全部随机接入时机，或者所述终端设备支持的带宽大于或等于初始上行带宽部分，或者所述第一随机接入时机集合已关联所述SSB；则终端设备也可以基于第一随机接入时机集合确定所述第一随机接入时机集合与SSB的关联关系；即将所述第一随机接入时机集合中的全部随机接入时机与所述SSB关联。在具体实施时，终端设备可以根据网络设备发送的第一配置信息确定所述第一随机接入时机集合与SSB的关联关系。针对第一随机接入时机集合内的随机接入时机已经覆盖第二随机接入时机集合内的全部随机接入时机，或者如附图7所示，虽然终端设备支持的带宽内的第一随机接入时机集合不能够覆盖初始上行带宽内的第二随机接入时机集合，但是，根据ssb-perRACH-Occasion参数，第二随机接入时机集合与SSB关联时，第二随机接入时机集合所包括的第一随机接入时机集合已经与终端设备的随机接入资源对应的全部SSB(索引0-7的SSB)关联的场景，终端设备可以基于第一随机接入时机集合确定所述第一随机接入时机集合与SSB的关联关系；即将所述第一随机接入时机集合中的全部随机接入时机与所述SSB关联。在具体实施时，终端设备可以根据网络设备发送的第一配置信息确定所述第一随机接入时机集合与SSB的关联关系。
还有一种可选实施方式中，若所述第一随机接入时机集合不包括所述第二随机接入时机集合内的全部随机接入时机，或者所述终端设备支持的带宽小于初始上行带宽部分，或者所述第一随机接入时机集合不能关联所述SSB，则所述终端设备可以基于第一随机接入时机集合确定所述第一随机接入时机集合与SSB的关联关系；即将所述第一随机接入时机集合中的全部随机接入时机与所述SSB关联。在具体实施时，终端设备可以根据网络设备发送的第一配置信息确定所述第一随机接入时机集合与SSB的关联关系。
其中，所述第一配置信息可以是网络设备向降低能力终端设备单独发送、用于配置第一随机接入时机集合与终端设备的随机接入资源所关联的全部SSB的关联关系；第一配置信息可以包括ssb-perRACH-Occasion参数和CB-PreamblesPerSSB参数中的至少一项，第一配置信息包括的 ssb-perRACH-Occasion参数和/或CB-PreamblesPerSSB参数可以是网络设备向降低能力终端设备单独发送的，适用于降低能力终端设备的参数；即用于配置第一随机接入时机集合与SSB的关联关系的ssb-perRACH-Occasion参数与用于配置第二随机接入时机集合与SSB的关联关系的ssb-perRACH-Occasion参数不是同一个。ssb-perRACH-Occasion参数也可以是网络设备向全部终端设备(包括传统的非降低能力终端设备以及降低能力终端设备)发送的，适用于全部终端设备的参数，即用于配置第一随机接入时机集合与SSB的关联关系的ssb-perRACH-Occasion参数与用于配置第二随机接入时机集合与SSB的关联关系的ssb-perRACH-Occasion参数可以是同一个。ssb-perRACH-Occasion参数用于配置几个SSB关联第一随机接入时机集合中的一个随机接入时机，或者1个SSB关联第一随机接入时机集合中的几个随机接入时机。降低能力终端设备在第一随机接入时机集合中使用的前导码与传统的非降低能力终端设备在第一随机接入时机集合中使用的前导码不同。以图5为例，降低能力终端设备在索引为2-5的随机接入时机使用的前导码与传统的非降低能力终端设备在索引为2-5的随机接入时机使用的前导码不同。
在一些实施例中，若终端设备根据网络设备发送的第一配置信息确定所述第一随机接入时机集合与SSB的关联关系，则所述终端设备还可以根据网络设备发送的第二配置信息，确定用于所述终端设备基于竞争的前导码数目，再根据用于所述终端设备的基于竞争的前导码数目确定每个所述SSB在所述第一随机接入时机集合中的每个随机接入时机上基于竞争的前导码的数目；具体的，终端设备CB-PreamblesPerSSB参数确定每个所述SSB在所述第一随机接入时机集合中的每个随机接入时机上基于竞争的前导码的数目。
上述实施方式中，由终端设备根据所述第一随机接入时机集合是否包括所述第二随机接入时机集合内的全部随机接入时机，或者所述终端设备支持的带宽是否大于或等于初始上行带宽部分，或者所述第一随机接入时机集合是否已关联所述SSB来判断如何确定第一随机接入时机集合与SSB的关联关系，如基于所述第二随机接入时机集合确定第一随机接入时机集合与SSB的关联关系，或者基于所述第一随机接入时机集合确定第一随机接入时机集合与SSB的关联关系。
在另一些实施例中，网络设备还可以向终端设备发送第三配置信息，第三配置信息指示基于所述第一随机接入时机集合确定所述第一随机接入时机集合与SSB的关联关系、或基于所述第二随机接入时机集合确定所述第一随机接入时机集合与所述SSB的关联关系。若第三配置信息指示基于所述第一随机接入时机集合确定所述第一随机接入时机集合与SSB的关联关系，则终端设备建立第一随机接入时机集合中的全部随机接入时机与SSB的关联关系；若第三配置信息指示基于所述第二随机接入时机集合确定所述第一随机接入时机集合与所述SSB的关联关系，该场景下，由于第一随机接入时机集合中包括第二随机接入时机集合的全部随机接入时机，则终端设备确定第二随机接入时机集合与所述SSB的关联关系为第一随机接入时机集合与所述SSB的关联关系。

在一些实施例中，网络设备根据所述第一随机接入时机集合是否包括网络设备为终端设备配置侧初始上行带宽部分中的第二随机接入时机集合内的全部随机接入时机，或者所述终端设备支持的带宽是否大于或等于初始上行带宽部分，或者所述第一随机接入时机集合是否已关联所述SSB来判断如何确定第一随机接入时机集合与SSB的关联关系，确定所述第一随机接入时机集合与SSB的关联关系。网络设备确定第一随机接入时机集合与SSB的关联关系的具体实现过程，与上述步骤S202 中终端设备根据所述第一随机接入时机集合是否包括网络设备为终端设备配置侧初始上行带宽部分中的第二随机接入时机集合内的全部随机接入时机，或者所述终端设备支持的带宽是否大于或等于初始上行带宽部分，或者所述第一随机接入时机集合是否已关联所述SSB来判断如何确定第一随机接入时机集合与SSB的关联关系，确定所述第一随机接入时机集合与SSB的关联关系的处理过程相同，这里不再赘述。

其中，所述第一配置信息可以是网络设备向降低能力终端设备单独发送、用于配置第一随机接入时机集合与终端设备的随机接入资源所关联的全部SSB的关联关系；第一配置信息可以包括ssb-perRACH-Occasion参数和CB-PreamblesPerSSB参数中的至少一项，第一配置信息包括的ssb-perRACH-Occasion参数和/或CB-PreamblesPerSSB参数可以是网络设备向降低能力终端设备单独发送的，适用于降低能力终端设备的参数；即用于配置第一随机接入时机集合与SSB的关联关系的ssb-perRACH-Occasion参数与用于配置第二随机接入时机集合与SSB的关联关系的ssb-perRACH-Occasion参数不是同一个。ssb-perRACH-Occasion参数可以是网络设备向全部终端设备(包括传统的非降低能力终端设备以及降低能力终端设备)发送的，适用于全部终端设备的参数，即用于配置第一随机接入时机集合与SSB的关联关系的ssb-perRACH-Occasion参数与用于配置第二随机接入时机集合与SSB的关联关系的ssb-perRACH-Occasion参数可以是同一个。
在一些实施例中，所述方法还可以包括：

下面以举例详细说明本申请实施例提供的随机接入资源确定方法。
现有技术中，通过ssb-PositionsInBurst指示的SSB中的每个SSB都关联了一个或者多个RACH时机，每个SSB也关联了多个Contention Based preambles。由于每个SSB对应一个SSB index，因此，每个SSB index关联了系统消息中指示的RACH资源配置中一部分特定的资源。在一些场景下，如果降低能力终端设备支持的带宽只能覆盖RACH资源中的部分随机接入时机，则降低能力终端设备所覆盖到的随机接入时机可能并不能关联到所有的SSB。当降低能力终端设备测量某个SSB的接收质量满足要求时，可能该SSB无法关联到降低能力终端设备支持的带宽内所包含的RO，导致降低能力终端设备无法选择对应的RACH资源发起接入。仍以图5为例，第一随机接入时机集合包括索引为2-5的随机接入时机，按照现有技术中SSB与随机接入时机的映射方式，降低能力终端设备支持的带宽内至包括索引为2-5的SSB所关联的RO。
本申请实施例中，对降低能力终端设备支持的带宽内包括的随机接入时机与SSB单独进行关联，而不是采用现有技术中SSB与频域内的所有RO进行关联。在具体实施时，网络设备可以为降低能力终端设备单独配置ssb-perRACH-Occasion和CB-PreamblesPerSSB参数；由于降低能力终端设备支持的带宽包括索引为2-5的随机接入时机，因此，网络设备可以为终端设备配置ssb-perRACH-Occasion＝2，即2个SSB关联一个降低能力终端设备支持的带宽内包括的RO。具体的，索引为0-7的SSB与降低能力终端设备支持的带宽包括的索引为2-5的随机接入时机关联，得 到的第一随机接入时机集合与SSB的关联关系，如索引为0和1的SSB关联索引为2的随机接入时机，索引为2和3的SSB关联索引为3的随机接入时机，索引为4和5的SSB关联索引为4的随机接入时机，索引为6和7的SSB关联索引为5的随机接入时机。
本申请实施例中，可以理解为索引为2-5的随机接入时机是传统的非降低能力终端设备与降低能力终端设备共享的随机接入时机，为了避免网络设备无法区分传统的终端设备和降低能力终端设备发送的随机接入资源所关联的SSB，在共享的随机接入时机中，传统的终端设备和降低能力终端设备可以使用不同的的前导码；在非共享的随机接入时机中，如索引为0,1,6和7的随机接入时机上映射的前导码仅供传统的终端设备使用。对于传统的终端设备，SSB与索引为0-7的随机接入时机关联，对于降低能力终端设备，SSB与索引为2-5的随机接入时机关联。
通过本申请实施例提供的随机接入资源确定方法，降低能力终端设备带宽内的全部随机接入时机可以映射到随机接入资源关联的所有SSB，当降低能力终端设备选定一个SSB时，可以获得该SSB关联的随机接入资源；因此，本申请实施例提供的随机接入资源确定方法能够为降低能力终端设备提供有效的随机接入资源。并且，本申请实施例提供的随机接入资源确定方法不需要降低能力终端设备进行调频，或者单独为降低能力终端设备配置单独的初始上行带宽部分，可以沿用现有的降低能力终端设备的配置，提高系统的兼容性，减少系统复杂度和资源开销。
下面针对虽然终端设备支持的带宽内的第一随机接入时机集合不能够覆盖初始上行带宽内的第二随机接入时机集合，但是，根据ssb-perRACH-Occasion参数，第二随机接入时机集合与SSB关联时，第二随机接入时机集合所包括的第一随机接入时机集合已经与终端设备的随机接入资源对应的全部SSB关联的场景，可以根据第二随机接入时机集合确定第一随机接入时机集合与SSB的关联关系，也可以根据第一随机接入时机集合确定第一随机接入时机集合与SSB的关联关系。仍以图7为例，当根据网络设备配置的ssb-perRACH-Occasion＝2，可以确定2个SSB关联第二随机接入时机集合中的一个随机接入时机；降低能力终端设备支持的带宽包含的索引为2-5的随机接入时机构成的第一随机接入时机集合，第一随机接入时机集合内的随机接入时机可以映射到索引为0-7的SSB，即第一随机接入时机集合内的随机接入时机可以映射到频域内的全部SSB。
或者，网络设备配置的第二随机接入集合占用的带宽在降低能力终端设备支持的带宽内，第一随机接入时机集合与SSB的关联关系可以由第二随机接入时机集合确定，该场景下，第一随机接入时机集合已经覆盖第二随机接入时机集合内的全部随机接入时机，因此第二随机接入时机集合与SSB的关联关系即为第一随机接入时机集合与SSB的关联关系。第一随机接入时机集合与SSB的关联关系的另一种可选示意图，如图9所示，网络设备配置的第二随机接入集合占用的带宽在降低能力终端设备支持的带宽内，索引为0和1的SSB关联索引为2的随机接入时机，索引为2和3的SSB关联索引为3的随机接入时机，索引为4和5的SSB关联索引为4的随机接入时机，索引为6和7的SSB关联索引为5的随机接入时机；因此，降低能力终端设备支持的带宽内的第一随机接入集合与频域内的全部SSB关联。
