Description

随机接入前导序列的发送和配置方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
目前，新无线(NR，New Radio)系统可以在以下两个频率范围内的频段(包括FR1和FR2)上工作，但还不支持在更高频段工作。
Figure PCTCN2021085750-appb-000001
为此，3GPP在Rel-17的标准化工作中将研究如何支持NR在更高频段(例如，在52.6-71GHz的频率范围内的频段)工作。上述更高频段范围包括非授权(或共享)频段。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
但是，发明人发现：针对上述更高频段(例如，在52.6-71GHz的频率范围内的频段)，目前还没有方案支持物理随机接入信道机会(PRACH Occasion)配置以及随机接入前导序列发送。
针对上述问题的至少之一，本申请实施例提供一种随机接入前导序列的发送和配置方法以及装置。
根据本申请实施例的一个方面，提供一种随机接入前导序列的发送方法，包括：
终端设备接收网络设备发送的随机接入配置信息；其中，所述随机接入配置信息至少用于配置用于发送随机接入前导序列的至少一个物理随机接入信道机会；以及

根据本申请实施例的另一个方面，提供一种随机接入前导序列的发送装置，包括：
接收单元，其接收网络设备发送的随机接入配置信息；其中，所述随机接入配置信息至少用于配置用于发送随机接入前导序列的至少一个物理随机接入信道机会；以及
选择单元，其从配置的至少一个物理随机接入信道机会中选择一个物理随机接入信道机会以发送所述随机接入前导序列。
根据本申请实施例的另一个方面，提供一种随机接入前导序列的发送方法，包括：
终端设备基于以下至少一项生成用于承载随机接入前导序列的基带信号：物理随机接入信道机会在部分带宽(BWP)中的第一索引，物理随机接入信道机会在第一资源块集合中的第二索引，第二资源块集合中在频域上包括的物理随机接入信道机会的数量。
根据本申请实施例的另一个方面，提供一种随机接入前导序列的发送装置，包括：

根据本申请实施例的另一个方面，提供一种随机接入前导序列的配置方法，包括：
网络设备向终端设备发送随机接入配置信息；其中，所述随机接入配置信息至少用于配置用于发送随机接入前导序列的至少一个物理随机接入信道机会。

发送单元，其向终端设备发送随机接入配置信息；其中，所述随机接入配置信息至少用于配置用于发送随机接入前导序列的至少一个物理随机接入信道机会。
本申请实施例的有益效果之一在于：随机接入配置信息至少用于配置用于发送随机接入前导序列的至少一个物理随机接入信道机会(PRACH occasion)。由此，即使针对频域中更高频段，也能够支持物理随机接入信道机会配置，提高了网络设备配置的灵活度，进而还减少了终端设备测量的复杂度和功耗。

图7是本申请实施例的随机接入前导序列的发送方法的一示意图，从终端设备和网络设备进行说明。如图7所示，该方法包括：
701，终端设备接收网络设备发送的随机接入配置信息；其中所述随机接入配置信息至少用于配置用于发送随机接入前导(preamble)序列的至少一个物理随机接入信道机会；以及
702，终端设备从配置的至少一个物理随机接入信道机会中选择一个物理随机接入信道机会以发送所述随机接入前导序列。
如图7所示，该方法还可以包括：
703，终端设备向网络设备发送随机接入前导序列。
值得注意的是，以上附图7仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图7的记载。
图8是一个载波的资源块(RB，Resource Block)和资源块集合(RB set)的一示例图；如图8所示，在频域上，每个资源块集合包括50个RB，两个资源块集合之间具有小区内保护频带(6个RB)。每个RB包括12个子载波(如SC 0至SC 11所示)。
图9是一个载波的部分带宽(BWP，Bandwidth Part)和该部分带宽配置的RO的一示例图，例如RO配置是per BWP的，RO的配置信息包含在其所在的BWP的配置信息中。如图9所示，RO映射在连续的资源块集合中，每个资源块集合映射一 个RO。此外，如图9所示，例如可以选择RO 1作为发送前导序列的资源。
图10是一个载波的资源块集合(RB set)和/或小区内保护频带和BWP的示例图。图10假设小区内保护频带的宽度为0，也就是说，该载波上没有小区内保护频带，但划分了资源块集。但不限于此，一个载波的资源块集合(RB set)和/或小区内保护频带也可以例如图8所示。一般地，BWP中包括整数个资源块集合。
在一些实施例中，随机接入配置信息配置的物理随机接入信道机会的频域资源在部分带宽(BWP)中。例如，一个BWP(UL BWP)的配置信息可以包括随机接入配置信息，则该随机接入配置信息配置的物理随机接入信道机会在该BWP中。
在一些实施例中，随机接入配置信息例如是rach-ConfigCommon(针对4-step RACH和/或2-step RACH)，msgA-ConfigCommon(针对2-step RACH)，rach-ConfigCommonIAB(针对IAB中的RACH，为IAB-MT配置)。在一些实施例中，随机接入配置信息例如包括在bwp-Common(或者说BWP-UplinkCommon)中。
在一些实施例中，一个物理随机接入信道机会的频域资源包括整数个RB。例如，该整数个RB的SCS是PRACH的SCS。
在一些实施例中，一个物理随机接入信道机会的频域资源包括整数个RB。例如，该整数个RB的SCS是该物理随机接入信道所在的BWP的SCS。
在一些实施例中，在频域上配置有多个物理随机接入信道机会的情况下，该多个物理随机接入信道机会中的至少两个在同一资源块集合中。也就是说，在配置的物理随机接入信道机会中，时域资源相同或交叠的(或者说频分复用(FDM，Frequency Division Multiplexing))多个物理随机接入信道机会中的至少两个物理随机接入信道机会的频域资源在同一资源块集合中。
本申请实施例中，随机接入配置信息至少用于配置用于发送随机接入前导序列的至少一个物理随机接入信道机会。由此，即使针对频域中更高频段，也能够支持物理随机接入信道机会配置。进一步地，部分带宽(BWP)中至少有一个资源块集合在频域上包括至少两个随机接入信道机会的频域资源，因此能够避免资源的碎片化。由此，提高了网络设备配置的灵活度，进而还减少了终端设备测量的复杂度和功耗。
在一些实施例中，随机接入配置信息包括第一指示信息(例如位置信息)和第二指示信息(例如个数信息)；终端设备根据第一指示信息和第二指示信息确定配置的物理随机接入信道机会的在部分带宽(BWP)中的频域位置。第一指示信息例如为 msg1-FrequencyStart，第二指示信息例如为msg1-FDM；但本申请不限于此。
在一些实施例中，第一指示信息表示BWP中的频域上第一个随机接入信道机会所在的第一个资源块(RB)与部分带宽(BWP)的第一个资源块(RB)之间的偏移，第二指示信息表示在部分带宽(BWP)中的频域上的物理随机接入信道机会的个数。
在一些实施例中，第一指示信息用于指示部分带宽(BWP)中的一个资源块集合中频域上第一个物理随机接入信道机会所在的第一个资源块(RB)与所述资源块集合的第一个资源块(RB)之间的偏移，所述第二指示信息用于指示所述资源块集合(RB set)中在频域上的物理随机接入信道机会的个数。
在一些实施例中，随机接入配置信息还包括第三指示信息，所述第三指示信息用于指示BWP中包括物理随机接入信道机会的资源块集合。
在一些实施例中，配置的至少一个物理随机接入信道机会中，时域资源相同或交叠的物理随机接入信道机会的频域资源是连续的。
在一些实施例中，时域资源相同或交叠的物理随机接入信道机会中，至少两个物理随机接入信道机会的频域资源在不同的资源块集合(RB set)中。
在一些实施例中，配置的至少一个物理随机接入信道机会中时域资源相同或交叠且频域资源在同一资源块集合中的物理随机接入信道机会的频域资源是连续的或者不连续的。
在一些实施例中，配置的至少一个物理随机接入信道机会的至少一个物理随机接入信道机会的频域资源与频域上的保护频带交叠。例如该保护频带为小区内保护频带(intra-cell guard band)。
也就是说，配置的物理随机接入信道机会的频域资源可以与小区内保护频带交叠。交叠例如是指，物理随机接入信道机会的频域资源中的至少N个子载波或者至少N个RB在小区内保护间隔的频域资源范围内，N>＝1。
图11是本申请实施例的BWP、资源块集合和RO的一示例图。如图11所示，例如BWP可以包括多个资源块集合1、2、3；在资源块集合1和资源块集合2之间包括小区内保护频带1，在资源块集合2和资源块集合3之间包括小区内保护频带2。
如图11所示，配置的随机接入信道机会RO 1、RO 2、RO 3和RO 4在部分带宽(BWP)上的频域资源是连续的，RO3的频域资源与小区内保护频带1交叠。RO 1和RO 2的频域资源在资源块集合1中，RO 4的频域资源在资源块集合2中；在资源 块集合1中的RO 1和RO 2的频域资源是连续的。
在一些实施例中，时域资源相同或交叠的多个随机接入信道机会(RO)的频域资源是连续的。例如，假设第一指示信息(例如，msg1-FrequencyStart)表示BWP的频域上第一个物理随机接入信道机会所在的第一个资源块(RB)与部分带宽(BWP)的第一个资源块(RB)之间的偏移，第二指示信息(例如，msg1-FDM)表示在部分带宽(BWP)的频域上的物理随机接入信道机会的个数，可以根据第一指示信息确定RO1的频域资源，进而根据第二指示信息确定与RO1时域资源相同或交叠的(FDMed)其他RO的频域资源；假设第二指示信息(例如msg1-FDM)指示的个数为4，则例如图11所示，BWP中频域上包括连续的4个RO，即RO 1至RO 4。
在一些实施例中，在配置的至少一个物理随机接入信道机会中，频域资源与频域上的保护频带交叠的物理随机接入信道机会是无效的物理随机接入信道机会。
也可以说，在配置的物理随机接入信道机会中，在频域上与小区内保护频带重叠的物理随机接入信道机会是无效的物理随机接入信道机会。例如，如图11所示，RO 3的频率资源与小区内保护频带1交叠，因此RO 3为无效的RO。
需要指出的是，图11中仅以一个时域位置上的RO作为示例，但本申请不限于此。BWP中可以包括在不同时域位置上的RO 1至RO 4，这些不同时域位置上的RO 3均为无效的RO。
在一些实施例中，无效的物理随机接入信道机会没有关联的同步信号块(SSB)。
在一些实施例中，终端设备不基于所述无效的物理随机接入信道机会确定物理随机接入信道机会与同步信号块(SSB)之间的关联关系。
例如，终端设备可以排除无效的RO后，再按照一定的顺序确定剩余的配置的RO和SSB之间的关联关系。
在一些实施例中，所述无效的物理随机接入信道机会有关联的同步信号块。
在一些实施例中，终端设备基于所述无效的物理随机接入信道机会确定物理随机接入信道机会与同步信号块(SSB)之间的关联关系。
例如，终端设备在进行RO的选择以发送PRACH时再排除该无效的RO。但本申请不限于此。例如还可以在计算RA-RNTI时排除该无效的RO。
在一些实施例中，终端设备从配置的至少一个物理随机接入信道机会中选择所述无效的物理随机接入信道机会以外的一个物理随机接入信道机会以发送所述随机接 入前导序列。
例如，终端设备从配置的随机接入信道机会中不选择(不能选择、或者不被允许选择、或不期望选择)无效的随机接入信道机会，或者，终端设备排除(能够排除、或者允许排除、或期望排除、或必须排除)无效的随机接入信道机会。终端设备选择其他的物理随机接入信道机会(非无效的RO)以发送所述随机接入前导序列。
在一些实施例中，配置的至少一个物理随机接入信道机会中，时域资源相同或交叠的物理随机接入信道机会的频域资源是不连续的。例如，时域资源相同或交叠的物理随机接入信道机会的频域资源是不连续的是指，时域资源相同或交叠的物理随机接入信道机会中的两个频域上相邻的RO之间存在间隔，该间隔例如为整数个RB。
在一些实施例中，配置的至少一个物理随机接入信道机会中时域资源相同或交叠且频域资源在同一资源块集合中的物理随机接入信道机会的频域资源是连续的或不连续的。
在一些实施例中，时域资源相同或交叠的物理随机接入信道机会中的至少两个物理随机接入信道机会的频域资源在不同的资源块集合(RB set)中。
在一些实施例中，时域资源相同或交叠的随机接入信道机会中，位于第一资源块集合(RB set)中的频域位置最高的物理随机接入信道机会的频域资源和位于第二资源块集合(RB set)中的频域位置最低的物理随机接入信道机会的频域资源是不连续的；第一资源块集合(RB set)和所述第二资源块集合(RB set)在频域上相邻且所述第一资源块集合(RB set)的频域位置低于所述第二资源块集合(RB set)的频域位置。
在一些实施例中，在频域上，不同资源块集合中的第一个RO的第一RB与其所在的资源块集合中的第一个CRB之间的偏移必须相同。例如，图9中RO 1与资源块集合1的第一个CRB之间的偏移为offset 1，RO 3与资源块集合2的第一个CRB之间的偏移为offset 2，offset 1和offset 2相同。图9中offset 1和offset 2例如为1个RB(或者是CRB)，该RB的SCS例如为BWP的SCS。
在一些实施例中，在频域上，不同资源块集合中包括的RO数量必须相同。
在一些实施例中，配置的至少一个物理随机接入信道机会的频域资源不与频域上的保护频带交叠。例如该保护频带为小区内保护频带(intra-cell guard band)。也就是说，配置的物理随机接入信道机会的频域资源不可以与小区内保护频带交叠。
图12是本申请实施例的BWP、资源块集合和RO的另一示例图。如图12所示，例如BWP可以包括多个资源块集合1、2、3；在资源块集合1和资源块集合2之间包括小区内保护频带1，在资源块集合2和资源块集合3之间包括小区内保护频带2。
如图12所示，配置的随机接入信道机会RO 1和RO 2的频域资源在资源块集合1中，RO 3和RO 4的频域资源在资源块集合2中；在资源块集合1中的RO 1和RO 2的频域资源是连续的，在资源块集合2中的RO 3和RO 4的频域资源是连续的。
如图12所示，配置的随机接入信道机会RO 1、RO 2、RO 3和RO 4在部分带宽(BWP)上的频域资源是不连续的；其中在资源块集合1中的RO 2与在资源块集合2中的RO 3的频域资源是不连续的。
如图12所示，配置的物理随机接入信道机会的频域资源不与小区内保护频带1交叠。需要指出的是，图12中仅以一个时域位置上的RO作为示例，但本申请不限于此，BWP中可以包括在不同时域位置上的RO 1至RO 4。
在一些实施例中，时域资源相同或交叠的物理随机接入信道机会在频域上按先资源块集合中的资源块索引升序再资源块集合索引升序被映射，或者，按BWP中的资源块索引升序被映射。
在一些实施例中，多个物理随机接入信道机会在一个资源块集合内按照资源块(RB)索引被连续映射；在所述资源块集合的剩余资源不能容纳一个物理随机接入信道机会的情况下，在下一个资源块集合内继续映射所述物理随机接入信道机会。
例如，按先资源块集合中的RB索引升序后资源块集合索引升序映射RO。资源块集合的频域资源中(按RB索引升序)连续映射RO，若剩余资源不足以映射一个RO，则下一个RO映射到另一个资源块集合。
例如，假设配置的第一个RO在BWP中的资源块集合X，配置的RO个数为M。若资源块集合X映射了第N个RO(M>N>＝1)后，剩余资源不足以映射一个RO，则第N+1个RO映射在BWP中的资源块集合X+1(其中，第N+1个RO的第一个RB与资源块集合X+1的第一个RB之间的offset例如和资源块集合X上的第1个RO的第一个RB与资源块集合X的第一个RB之间的offset相同)，再继续映射后续的RO，依此类推，直到映射完M个RO。
以图12为例，例如，假设msg1-FrequencyStart表示BWP的频域上第一个随机接入信道机会所在的第一个资源块(RB)与部分带宽(BWP)的第一个资源块(RB) 之间的偏移，msg1-FDM表示在部分带宽(BWP)的频域上的随机接入信道机会的个数，并且msg1-FDM＝4；
如图12所示，在资源块集合1中可以按照RB索引升序在频域上从低到高映射RO 1和RO 2，在资源块集合2中可以按照RB索引升序在频域上从低到高映射RO 3和RO 4，而在资源块集合之间可以按照资源块集合索引升序在频域上从低到高映射RO 2和RO 3。
在一些实施例中，时域资源相同或交叠的物理随机接入信道机会在频域上按先资源块集合索引(RB set index)升序再资源块集合中的资源块索引(RB index)升序被映射。其中，多个物理随机接入信道机会按照资源块集合索引逐个地被映射；在最后一个资源块集合映射物理随机接入信道机会后仍有剩余物理随机接入信道机会的情况下，从第一个资源块集合继续逐个地被映射。
图13是本申请实施例的BWP、资源块集合和RO的另一示例图。如图13所示，例如BWP可以包括多个资源块集合1、2、3；在资源块集合1和资源块集合2之间包括小区内保护频带1，在资源块集合2和资源块集合3之间包括小区内保护频带2。
如图13所示，配置的随机接入信道机会RO 1和RO 4的频域资源在资源块集合1中，RO 2的频域资源在资源块集合2中，RO 3的频域资源在资源块集合3中；在资源块集合1中的RO 1和RO 4的频域资源是连续的。
如图13所示，配置的随机接入信道机会RO 1、RO 2、RO 3和RO 4在部分带宽(BWP)上的频域资源是不连续的。配置的物理随机接入信道机会的频域资源不与小区内保护频带1和小区内保护频带2交叠。
例如，msg1-FrequencyStart表示BWP的频域上第一个RO所在的第一个RB与其所在的BWP的第一个RB之间的偏移，msg1-FDM表示在BWP的频域上的RO个数。按先资源块集合索引升序后资源块集合中的RB索引升序映射RO。
例如，假设配置的第一个RO在BWP中的资源块集合X，配置的RO个数为M。若资源块集合X映射了第1个RO，在资源块集合X+1映射第2个RO，若在资源块集合Y映射第N个RO(M>N>＝1)且资源块集合Y是最后一个资源块集合，则第N+1个RO映射到资源块集合X，其频域资源与第1个RO的频域资源连续。依此类推，直到映射完M个RO。
以图13为例，例如，假设msg1-FrequencyStart表示BWP的频域上第一个物理 随机接入信道机会所在的第一个资源块(RB)与部分带宽(BWP)的第一个资源块(RB)之间的偏移，msg1-FDM表示在部分带宽(BWP)的频域上的物理随机接入信道机会的个数，并且msg1-FDM＝4。
如图13所示，在资源块集合1中可以按照RB索引升序在频域上从低到高先映射RO 1，在资源块集合2中可以按照RB索引升序在频域上从低到高映射RO 2，在资源块集合3中可以按照RB索引升序在频域上从低到高先映射RO 3；然后按照资源块集合索引，在资源块集合1中可以按照RB索引升序在频域上从低到高再映射RO 4。
需要指出的是，图13中仅以一个时域位置上的RO作为示例，但本申请不限于此。BWP中可以包括在不同时域位置上的RO 1至RO 4。
在一些实施例中，第一指示信息表示BWP的频域上第一个物理随机接入信道机会所在的第一个资源块(RB)与所述部分带宽(BWP)的第一个资源块(RB)之间的偏移，所述第二指示信息表示在所述部分带宽中包括物理随机接入信道机会的一个资源块集合(RB set)的频域上的随机接入信道机会的个数。
图14是本申请实施例的BWP、资源块集合和RO的另一示例图。例如，假设msg1-FrequencyStart表示BWP的频域上第一个物理随机接入信道机会所在的第一个资源块(RB)与部分带宽(BWP)的第一个资源块(RB)之间的偏移，msg1-FDM表示在该BWP包括物理随机接入信道机会的一个资源块集合的频域上的物理随机接入信道机会的个数，并且msg1-FDM＝2。
如图14所示，在资源块集合1中可以按照RB索引升序在频域上从低到高映射RO 1和RO 2(共2个)，在资源块集合2中可以按照RB索引升序在频域上从低到高映射RO 3和RO 4(共2个)，在资源块集合3中可以按照RB索引升序在频域上从低到高映射RO 5和RO 6(共2个)。
需要指出的是，图14中仅以一个时域位置上的RO作为示例，但本申请不限于此。BWP中可以包括在不同时域位置上的RO 1至RO 6。
在一些实施例中，资源块集合和/或小区内保护频带被预定义(预定义的小区内保护频带例如称为Nominal intra-cell guard band)，或者，所述资源块集合和/或小区内保护频带通过小区公共信令(例如PBCH、MIB、SIB等)被配置。
以上示意性说明了如何基于预定义或小区公共信令配置的资源块集合和/或小区 内保护频带的配置/确定RO的频域资源。根据上述实施例，可以在一个资源块集合的频域上配置多个RO，并使得该多个RO的频域资源尽可能连续，进而尽量避免RO配置导致资源的碎片化，提高网络设备调度其他数据传输的灵活度。
另一方面，针对上述更高频段，小区内保护频带和/或资源块集合可能出现以下情况，以下结合不同情况对RO配置进行说明：
(1)没有预定义的小区内保护频带和/或资源块集合，也不可以通过小区公共(cell-common)信令和/或UE专用(UE dedicated)信令配置小区内保护频带和/或资源块集合。
(2)没有预定义的小区内保护频带和/或资源块集合，可以通过小区公共(cell-common)信令和/或UE专用(UE dedicated)信令配置小区特定的(cell-specific)的小区内保护频带和/或资源块集合。
(3)没有预定义的小区内保护频带和/或资源块集合，可以通过UE专用的RRC信令配置UE特定的小区内保护频带和/或资源块集合。
(4)没有预定义的小区内保护频带和/或资源块集合，可以通过小区公共信令和/或UE专用信令配置小区特定的小区内保护频带和/或资源块集合，可以通过UE专用的RRC信令配置UE特定的小区内保护频带和/或资源块集合。
(5)有预定义的小区内保护频带和/或资源块集合，不可以通过小区公共(cell-common)信令和/或UE专用(UE dedicated)配置小区内保护频带和/或资源块集合。
(6)有预定义的小区内保护频带和/或资源块集合，可以通过小区公共信令和/或UE专用信令配置小区特定的小区内保护频带和/或资源块集合。
(7)有预定义的小区内保护频带和/或资源块集合，可以通过UE专用的RRC信令配置UE特定的小区内保护频带和/或资源块集合。
(8)有预定义的小区内保护频带和/或资源块集合，可以通过小区公共信令和/或UE专用信令配置小区特定的小区内保护频带和/或资源块集合，可以通过UE专用RRC信令配置UE特定的小区内保护频带和/或资源块集合。
在一些实施例中，假设没有预定义的小区内保护频带和/或资源块集合，也不可以通过小区公共(cell-common)信令和/或UE专用(UE dedicated)信令配置小区特定的(cell-specific)的小区内保护频带和/或资源块集合，例如上述(1)(3)所述， 配置的至少一个物理随机接入信道机会中，时域资源相同或交叠的(FDMed)物理随机接入信道机会的频域资源是连续的。
在一些实施例中，假设有预定义的小区内保护频带和/或资源块集合，如上(5)至(8)所述，可以根据预定义的小区内保护频带和/或资源块集合采用前述实施例配置/确定RO的频域资源。其中，如果还可以通过小区公共信令和/或UE专用信令配置小区特定的小区内保护频带和/或资源块集合，如上(6)(8)所述，则可以在配置了小区特定的小区内保护频带和/或资源块集合的情况下，根据配置的小区特定的小区内保护频带和/或资源块集合采用前述实施例配置/确定RO的频域资源；在没有配置小区内保护频带和/或资源块集合配置的情况下，根据预定义的小区内保护频带和/或资源块集合采用前述实施例配置/确定RO的频域资源。
在一些实施例中，假设根据预定义的小区内保护频带和/或资源块集合，RRC信令配置的小区特定的小区内保护频带和/或资源块集合，在相应载波/BWP(配置的RO所在的载波/BWP)不包括小区内保护频带的情况下，配置的至少一个物理随机接入信道机会中，时域资源相同或交叠的(FDMed)物理随机接入信道机会的频域资源是连续的。
以下再对PRACH(或者说PRACH occasion)的SCS进行说明。
在一些实施例中，物理随机接入信道(PRACH)机会的子载波间隔(SCS)为120kHz或480KHz或960KHz。
在一些实施例中，PRACH所在的BWP的子载波间隔为120kHz或480KHz或960KHz。
在一些实施例中，PRACH的子载波间隔与其所在的BWP的子载波间隔相同或不同。
在一些实施例中，终端设备可以根据PRACH所在的BWP的子载波间隔确定PRACH的子载波间隔。
在一些实施例中，物理随机接入信道(PRACH)机会的子载波间隔(SCS)与同步信号块(SSB)和/或信道状态信息参考信号(CSI-RS)子载波间隔(SCS)相同。该同步信号块(SSB)和/或信道状态信息参考信号(CSI-RS)例如是物理随机接入信道(PRACH)机会关联的同步信号块(SSB)和/或信道状态信息参考信号(CSI-RS)，或者物理随机接入信道所在的小区的同步信号块(SSB)，或者与初始DL BWP关联 的同步信号块(SSB)。例如，这种情况下，无需额外指示PRACH的SCS。终端设备例如可以根据上述同步信号块(SSB)和/或信道状态信息参考信号(CSI-RS)子载波间隔(SCS)确定PRACH的子载波间隔。
在一些实施例中，物理随机接入信道(PRACH)机会的子载波间隔(SCS)通过无线资源控制(RRC)信令被指示。例如，用于指示物理随机接入信道(PRACH)机会的子载波间隔(SCS)的指示信息(field)可以包括在随机接入配置信息中。例如，该指示信息可以指示PRACH的SCS为120kHz，480kHz或960kHz。
在一些实施例中，可以对随机接入配置信息中已包括的用于指示PRACH SCS的信息域进行修改，该信息域例如可以为如下之一或组合：RACH-ConfigCommon中的msg1-SubcarrierSpacing，RACH-ConfigCommonTwoStepRA中的msgA-SubcarrierSpacing-r16；在另一些实施例中，可以在随机接入配置信息中加入用于指示PRACH SCS的新的信息域。
在一些实施例中，仅针对L＝139的情况通过无线资源控制(RRC)信令指示PRACH的SCS。针对L＝571或1151的情况，UE可以根据频段确定PRACH的子载波间隔。例如，若是FR1，则L＝571对应的PRACH的子载波间隔是30kHz，L＝1151对应的PRACH的子载波间隔是15kHz；若是FR2或上述更高频段，则PRACH的子载波间隔为120kHz。
在一些实施例中，针对系统信息块配置的物理随机接入信道机会，物理随机接入信道(PRACH)机会的子载波间隔(SCS)与关联的同步信号块(SSB)和/或信道状态信息参考信号(CSI-RS)子载波间隔(SCS)相同；针对无线资源控制(RRC)信令配置的物理随机接入信道机会，物理随机接入信道(PRACH)机会的子载波间隔(SCS)通过所述无线资源控制(RRC)信令被指示。
在一些实施例中，针对基于竞争的随机接入(CBRA)，物理随机接入信道(PRACH)机会的子载波间隔(SCS)与关联的同步信号块(SSB)的子载波间隔(SCS)相同；针对免竞争的随机接入(CFRA)，物理随机接入信道(PRACH)机会的子载波间隔(SCS)通过无线资源控制(RRC)信令被指示。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知，随机接入配置信息至少用于配置用于发送随机接入前导序列的至少一个物理随机接入信道机会。由此，即使针对频域中更高频段，也能够支持物理随机接入信道机会配置，提高了网络设备配置的灵活度，进而还减少了终端设备测量的复杂度和功耗。
第二方面的实施例
本申请实施例提供一种随机接入前导序列的发送方法，在第一方面的实施例的基础上再进一步进行说明，与第一方面的实施例相同的内容不再赘述。第二方面的实施例可以与第一方面的实施例结合起来，也可以单独实施。
在一些实施例中，终端设备选择用于发送随机接入前导序列的随机接入信道机会；所述终端设备基于以下至少一项生成用于承载随机接入前导序列的基带信号：物理随机接入信道机会在部分带宽(BWP)中的第一索引，物理随机接入信道机会在第一资源块集合中的第二索引，第二资源块集合中在频域上包括的物理随机接入信道机会的数量。
在一些实施例中，第一索引是物理随机接入信道机会在BWP中的频域上的索引。
在一些实施例中，第一索引按BWP中物理随机接入信道机会的频域位置升序地被编号。例如，物理随机接入信道机会在BWP中的索引从BWP中的最低频率开始按升序编号。
在一些实施例中，第二索引是物理随机接入信道机会在第一资源块集合中的频域上的索引。
在一些实施例中，第二索引按第一资源块集合中物理随机接入信道机会的频域位置升序地被编号。例如，物理随机接入信道机会在资源块集合中的索引从资源块集合中的最低频率开始按升序编号。
在一些实施例中，第一资源块集合是该物理随机接入信道所在的资源块集合。
在一些实施例中，第二资源块集合是频域上第一个物理随机接入信道机会所在的资源块集合。例如，第二资源块集合是BWP中频域上第一个物理随机接入信道机会所在的资源块集合。
在一些实施例中，第二资源块集合是所述BWP中配置了物理随机接入信道机会的资源块集合，并且所述BWP中配置了物理随机接入信道机会的资源块集合在频域 上包括的物理随机接入信道机会的数量相同。
图15是本申请实施例的第一索引和第二索引的一示例图，以图14中的RO 1至RO 6为例进行说明。例如，如图15所示，对于RO 1，第一索引(1 st index)为0，第二索引(2 nd index)为0；对于RO 2，第一索引(1 st index)为1，第二索引(2 nd index)为1；对于RO 3，第一索引(1 st index)为2，第二索引(2 nd index)为0；对于RO 4，第一索引(1 st index)为3，第二索引(2 nd index)为1；对于RO 5，第一索引(1 st index)为4，第二索引(2 nd index)为0；对于RO 6，第一索引(1 st index)为5，第二索引(2 nd index)为1。
在一些实施例中，例如，终端设备采用以下方式生成PRACH的基带信号(即用于承载随机接入前导序列的基带信道)。
