在进行本申请实施例的说明时，首先对下面描述中所用到的一些概念进行解释说明。
一、随机接入过程。
随机接入过程可以是基于竞争的随机接入流程也可以是基于非竞争的随 机接入的过程。随机接入过程可以是四步随机接入过程(又叫类型(Type)-1随机接入过程)或者两步随机接入过程(又叫Type-2随机接入过程)。
(1)4步随机接入过程(4-step RACH)：
在竞争的4步随机接入过程中，UE首先向网络侧设备发送Msg1，包含前导序列(preamble)；网络检测到preamble后，将发送Msg2/随机接入响应(Random Access Response，RAR)消息，包含网络侧设备所检测到的preamble的编号，以及分配给UE发送Msg3的上行无线资源；UE接收到Msg2后，确认Msg2中携带的preamble的编号中，至少有一个和自己所发送的preamble的编号一致，则根据RAR的指示的资源，发送包含竞争解决信息的Msg3；网络侧设备收到Msg3后，将发送包含竞争解决信息的Msg4；UE收到Msg4，确认进行解决信息和自己在Msg3中发送的一致，即完成4步随机接入。
网络侧设备在RAR中包含上行链路授权(UpLink grant，UL grant)信息用于指示Msg3物理上行共享信道(Physical Uplink Shared Channel，PUSCH)调度信息，并且包含随机接入前导码标识(RACH preamble ID，RAPID)、临时的小区无线网络临时标识(Temporary Cell Radio Network Temporary Identifier，TC-RNTI)、定时提前(Timing Advance，TA)等信息。如果网络侧设备没有接收到Msg3 PUSCH，可以在TC-RNTI加扰的物理下行控制信道(Physical downlink control channel，PDCCH)中调度Msg3 PUSCH的重传。
对于竞争的随机接入过程，不同的UE随机选取preamble进行传输，这样不同的UE可能在相同的时频无线资源上选取相同的preamble发送，这种情况可以理解为UE的preamble冲突。这种情况下，不同的UE会收到相同的RAR，则此时不同的UE会根据该RAR UL grant中的调度信息，进行Msg3 PUSCH的传输。在不支持Msg3 PUSCH的重复传输时，网络侧设备在一个Msg3 PUSCH调度资源上只能解出一个UE发送的PUSCH(包含竞争解决信息)，所以，网络侧设备会在Msg4中包含在Msg3中收到的竞争解决信息。如果UE收到的Msg4中的竞争解决信息和UE在Msg3 PUSCH中发送的竞争解决信息匹配，则UE认为竞争解决成功。如果不匹配，则认为竞争解决不成功。
如果竞争解决不成功，则UE重新选择RACH发送资源，进行PRACH 发送，进行下一次随机接入尝试。
(2)两步随机接入过程(2-step RACH)：
第一步是UE发送MsgA给网络侧。网络侧接收到MsgA后给UE发送MsgB消息给UE，如果UE在一定时间内都没有收到MsgB，UE会将统计MsgA发送次数的计数器累加一并重新发送MsgA。如果统计MsgA发送次数的计数器达到一定门限，UE会从2-step随机接入过程切换到4-step随机接入过程。MsgA包括MsgA preamble部分和MsgA PUSCH部分，preamble部分在用于2-step RACH的RO上发送，PUSCH部分在跟发送MsgA preamble以及RO想关联的MsgA PUSCH资源上发送。MsgA PUSCH资源是相对于每个物理随机接入信道时隙(PRACH slot)配置的一组PUSCH资源，包括时频资源和解调参考信号(Demodulation Reference Signal，DMRS)资源。
二、随机接入资源的选择及同步信号块(Synchronization Signal and PBCH block，SSB)到RO的映射(mapping)。
在NR中，小区可以在一个传输PRACH的时域位置上，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)，又或者叫PRACH Occasion，这里为了简单简称为RO。在一个时刻，可以进行FDM的RO个数可以为：{1,2,4,8}。如图2所示，一个时刻，有8个RO资源分布在不同的频率上。
随机接入前导(Preamble)只能在参数PRACH配置索引(PRACHConfigurationIndex)配置的时域资源(即RO资源)上传输，随机接入前导只能在参数prach-FDM配置的频域资源上传输，PRACH频域资源n RA∈{0,1,…M-1}，其中M等于高层参数prach-FDM。在初始接入时，PRACH频域资源n RA从初始激活上行部分带宽(initial active uplink bandwidth part)内频率最低RO资源开始升序编号，否则，PRACH频域资源n RA从激活上行部分带宽(active uplink bandwidth part)内频率最低RO资源开始升序编号。如图2所示，RO资源按照频率从低到高，依次编号为RO#0～RO#7。
在NR中，RO和实际发送的SSB之间存在关联关系：
一个SSB可能关联多个RO，也可以多个SSB关联1个RO(这种情况下，不同SSB对应不同的Preamble码)。通常，基站可以采用不同的波束进 行不同的SSB的发送，对应的UE在与SSB关联的RO上发送Preamble，这样，UE根据接收到的下行波束/SSB的强度，选择信号好的SSB所关联的RO/“RO和preamble组合”，进行Msg1发送。这样，网络侧设备就可以根据接收到的Preamble的RO/“RO和preamble组合”，确定出UE所选择的SSB。并在SSB对应的下行波束上，发送Msg2，以确保下行信号的接收质量。
以图2为例，一个时刻上的FDM的RO数目为8个，实际传输的SSB数目为4个，即SSB#0、SSB#1、SSB#2、SSB#3，每个SSB关联2个RO。如果UE确定在SSB#0对应的RO上发送PRACH/Msg1/Preamble，那么UE在RO#0和RO#1中选择一个RO进行PRACH的发送。
以图3为例，一个时刻上的FDM的RO数目为2个，实际传输的SSB数目为8个，即SSB#0、SSB#1、……、SSB#7，每2个SSB关联1个RO。多个SSB共享一个RO时，该多个SSB关联的preamble集合是不同的，即同一个preamble也不能同时归属不同SSB关联的preamble集合。以图3中RO#0为例，其有60个与SSB关联的preamble，其中索引(index)为0～29的preamble与SSB#0关联，index为30～59的preamble与SSB#1关联。需要说明的是，图3中的每一个方格均用于表示RO，而不是SSB，其中标明的SSB是指该RO和哪个/哪些SSB是关联的。
UE发送PRACH前，首先进行资源选择，首先根据接收到的波束(beam)或SSB的参考信号接收功率(Reference Signal Received Power，RSRP)，选择RSRP高于门限的SSB；如果有多个SSB的RSRP高于该门限，终端可以选择任一个RSRP高于门限的SSB；若没有RSRP高于门限的SSB，UE基于实现选择一个SSB。
基于网络(Network，NW)的配置，UE获得SSB和RO的对应关系；在选择了SSB之后，所选SSB对应的RO被作为发送PRACH/Preamble的RO。如果所选SSB关联多个RO，终端可以选择其中一个RO进行PRACH/Preamble发送。
例如：在图2所示的实施例中，假设UE选择了SSB#1，UE可以从RO#2和RO#3中选择一个进行PRACH/Preamble发送；在图3所示的实施例中，假如UE选择了SSB#1,则UE可以选择与SSB#1关联的RO(RO#0或RO#4) 中距离当前时间最近的可用的RO进行PRACH/Preamble发送。
在所选择的RO中，UE在所选SSB关联的preamble集合中选择一个preamble进行PRACH的发送。如图3中，一个RO关联2个SSB，那么一个RO中与SSB关联的可用的Preamble集合中，preamble会被分成两个子集，每个子集对应于一个SSB。UE将选取对应于所选SSB的那个preamble子集里的某个preamble序列用于PRACH的发送。
其中，SSB与PRACH资源之间的关联有SSB to PRACH occasion mapping cycle(SSB到PRACH occasion的映射周期)、SSB to PRACH occasion mapping association period(SSB至PRACH occasion的映射关联周期)，以及SSB to PRACH occasion association pattern period(SSB至PRACH occasion的映射模式周期)。这些周期时间的目的主要是为了能够在预定义的一个时间段内至少完成一次随机接入尝试并且能以一定的模式重复PRACH资源跟SSB之间的映射。当PRACH重复时，PRACH重复需要确保这样的模式不能被打破。
三、在PRACH与其他信号或者时分复用(Time Division Duplex，TDD)配置的冲突时的处理方法。
1)如果在关联周期(association period)内的整数个SS/PBCH块索引到PRACH时机映射周期(mapping cycle)之后，有一组PRACH occasions或PRACH序列未映射到SS/PBCH块索引(SSB index)，则没有SS/PBCH块索引映射到PRACH occasions或PRACH序列。这些PRACH资源将不能用于PRACH的发送。
2)关联模式周期包括一个或多个关联周期，并且被确定为使得PRACH occasions和SS/PBCH块索引(SSB indexes)之间的模式最多每160毫秒重复一次。在整数个关联周期之后与SS/PBCH块索引不关联的PRACH occasions(如果有的话)不用于PRACH传输。
3)如果MsgA PUSCH occasion在时间和频率上不与任何与第一类型随机接入过程或第二类型随机接入过程相关的有效PRACH occasions重叠，则MsgA PUSCH occasion有效。这就意味着当PRACH与MsgA PUSCH资源重叠时，传输PRACH而不是传输MsgA PUSCH。
4)对于在未配对频谱(例如，时分复用(Time Division Duplex，TDD)) 中的单个载波上的操作，如果UE由更高层(higher layer)配置为在某个时隙(slot)的一组符号中接收PDCCH、物理下行共享信道(Physical downlink shared channel，PDSCH)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)或下行链路定位参考信号(DL Positioning Reference Signal，DL-PRS)，则如果UE在这组符号集合中的至少一个符号中未检测到指示UE发送PUSCH、PUCCH、PRACH或者SRS的下行控制信息(Downlink Control Information，DCI)格式，则UE接收PDCCH、PDSCH、CSI-RS或DL-PRS，否则UE不接收PDCCH、PDSCH、CSI-RS或DL-PRS。
5)对于在未配对频谱中的单个载波上的操作，如果UE由更高层配置为在时隙的一组符号中发送探测参考信号(Sounding Reference Signal，SRS)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、PUSCH或PRACH，并且UE检测到指示UE从该组符号的一个子集中接收CSI-RS或PDSCH的DCI格式，则：
如果UE不具备“部分取消(partialCancellation)”的能力，则如果该集合(发送SRS、PUCCH、PUSCH或PRACH的一组符号)中的第一个符号和UE检测到DCI格式的控制资源集(Control resource set，CORESET)的最后一个符号之间的时间间隔不超过T proc,2，则UE不期望取消该集合中的PUCCH或PUSCH或PRACH的传输；否则，UE取消PRACH传输，或者根据相关协议决定取消PUCCH，PUSCH，或PUSCH的实际重复的发送。
如果UE具备“部分取消(partialCancellation)”的能力，则如果该集合(发送SRS、PUCCH、PUSCH或PRACH的一组符号)中有一部分符号和UE检测到DCI格式的CORESET的最后一个符号之间的时间间隔不超过T proc,2，则UE不期望在这一部分符号上取消PUCCH或PUSCH或PRACH的传输；对于这一部分符号外的符号，UE取消PRACH传输，或者根据相关协议决定取消PUCCH、PUSCH或PUSCH的实际重复的发送。
需要说明的是，在本申请的实施例中，RACH Occasion(即RO)与PRACH Occasion都是指用于发送一个PRACH序列所需要的时频资源，即RACH Occasion和PRACH Occasion均可以用RO表示。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的确 定PRACH重复传输资源的方法进行详细地说明。
如图4所示，本申请实施例提供一种确定PRACH重复传输资源的方法，应用于终端，所述方法包括：
步骤401、终端获取针对物理随机接入信道PRACH重复传输的资源配置信息，所述资源配置信息指示所述PRACH重复传输的配置资源。
该实施例中，所述PRACH重复传输与PRACH重传的定义不同，本申请实施例的PRACH重复是指在每次PRACH初传或者重传过程中做的重复传输，PRACH重复只发生在随机接入响应窗口(RAR window)结束之前。
所述针对PRACH重复传输的资源配置信息可以为网络侧设备配置，即网络侧设备为终端配置PRACH重复传输的资源。所述配置资源是指网络侧设备为终端配置的用于PRACH repetition传输的资源，并不一定是终端进行PRACH repetition传输实际使用的传输资源。PRACH repetition的资源指用于发送PRACH repetition的PRACH资源；不支持PRACH repetition的PRACH资源指用于发送PRACH但是没有做repetition的PRACH资源。PRACH资源可以是PRACH时频资源和/或PRACH序列。
步骤402、所述终端确定所述配置资源是否用于PRACH重复传输。
终端根据所述资源配置信息获取网络侧设备为其配置的配置资源，并确定所述配置资源是否实际用于PRACH重复传输。
本申请的实施例，终端获取针对PRACH重复传输的配置资源，并确定所述配置资源是否实际用于PRACH重复传输，使终端利用能够实际用于PRACH重复传输的配置资源进行PRACH重复发送，能够降低随机接入延时。
作为一个可选实施例，所述确定所述配置资源是否用于PRACH重复传输，包括以下至少一项：
(1)根据所述配置资源的有效性，确定所述配置资源是否用于PRACH重复传输；
(2)根据所述配置资源所在符号的配置信息，确定所述配置资源是否用于PRACH重复传输；
(3)根据所述配置资源与其他信号资源的冲突情况，确定所述配置资源是否用于PRACH重复传输。
该实施例中，终端可以根据配置资源的有效性、配置资源所在符号的配置信息、配置资源与其他信号资源的冲突情况中的一种或者多种方式的组合，确定配置资源是否能够实际用于PRACH重复传输。可选地，在根据所述配置资源的有效性确定所述配置资源是否能够实际用于PRACH重复传输时，所述方法还可以包括：
确定所述配置资源的有效性；其中，所述配置资源的有效性，与第一间隙要求和/或时分复用TDD上下行链路配置相关；
所述第一间隙要求为SSB传输、用于SSB传输的符号集、用于PRACH传输的符号集三者之间的间隙要求。
该实施例中，在基于配置资源的有效性确定是否实际用于PRACH重复传输时，配置资源验证有效性的方法可以与现有技术中不进行重复传输的PRACH资源的有效性验证方法相同，即配置资源是否有效取决于SSB传输、用于SSB传输的符号集和用于RPACH传输的符号集之间的间隙要求以及小区特定的TDD上行链路-下行链路配置。
可选地，对于可以同时发送PRACH重复传输和PRACH非重复传输的公共配置的资源，配置资源的有效性验证规则在两种PRACH传输情况下应相同，因此可以使用PRACH非重复传输的验证规则验证本申请实施例中的配置资源的有效性。
验证有效性的方法例如：对于成对频谱或额外的上行链路频谱，所有PRACH情况均有效；
对于未配对频谱：
如果未提供UE公共的TDD上下行链路配置(tdd-UL-DL-ConfigurationCommon)，如果PRACH时隙中的PRACH occasion不在PRACH时隙中的SS/PBCH block之前，并且在最后一个SS/PBCH block接收符号之后至少N gap个符号，则PRACH时隙中的PRACH occasion有效；其中，现有协议中提供了N gap，并且如果提供了channelAccessMode＝semistatic，则在UE不传输的下一信道占用时间开始之前，不与一组连续符号重叠。
如果向UE提供tdd-UL-DL-ConfigurationCommon，则PRACH slot中的PRACH occasion在以下情况下有效：
在UL符号范围内；或者，
不在PRACH时隙中的SS/PBCH block之前，且在最后一个下行线链路符号之后至少N gap个符号，且在最后一个SS/PBCH block符号之后至少N gap个符号。其中，现有协议中提供了N gap，并且如果提供了channelAccessMode＝semistatic，则在下一信道占用时间开始之前，不与一组连续符号重叠，其中不应存在任何传输；
SS/PBCH块的候选SS/PBCH块索引对应于SIB1或ServingCellConfigCommon中ssb-PositionsInBurst提供的SS/PBCH块索引。
需要说明的是，本申请实施例判断配置资源有效性的方法仅为示例性说明，也可以根据其他判断方式确定所述配置资源的有效性，在此不做限定。
下面通过具体实施例说明通过上述三种方式确定所述配置资源是否实际用于PRACH重复传输的具体实现过程。
作为一个可选实施例，所述根据所述配置资源的有效性，确定所述配置资源是否用于PRACH重复传输，包括以下至少一项：
1)根据所述配置资源中的第一RO的有效性，确定所述第一RO是否用于PRACH重复传输。
所述配置资源中包括针对PRACH重复传输配置的RO资源。所述第一RO为仅用于PRACH重复传输的RO，所述第一RO可以包括一个或者多个RO。该实施例根据额外配置的仅用于进行PRACH重复传输的RO的有效性，确定该RO是否能够实际用于PRACH重复传输。
可选地，所述根据所述配置资源中的第一RO的有效性，确定所述第一RO是否用于PRACH重复传输，包括：若所述第一RO中的第一目标RO无效，则确定所述第一目标RO不用于PRACH重复传输。
该实施例中，所述第一目标RO可以是指所述第一RO中的一个或者多个RO，对于仅用于进行PRACH重复传输的RO，若该RO无效，则该RO被丢弃，不能用于进行PRACH重复传输。其中，在第一目标RO无效被丢 弃时，可以不对该第一目标RO进行计数，也可以对该第一目标RO进行计数。下面分别说明。
可选地，所述方法还包括：将所述第一目标RO推迟一个RO级别的时域位置，获得第二目标RO，所述第二目标RO用于PRACH重复传输。
该情况下，在第一目标RO无效时，不对该第一目标RO进行计数，可以将无效的第一目标RO推迟，获得新的有效的第二目标RO，从而确保有效的PRACH repetition数量。例如图5所示，所述配置资源包括公共RO和第一RO，公共RO用于进行第一次PRACH repetition，第一RO包括用于PRACH repetition的RO0、RO1、RO2、RO3，且RO0、RO1、RO2、RO3各两个，可以分别进行两次PRACH repetition，其中，1个RO0和1个RO1由于与SSB传输重叠而无效(即图5中右侧的1个RO0和1个RO1为所述第一目标RO)，则将无效的RO0和RO1向后顺延一个RO，从而确保有对应的额外两个RO用于PRACH repetition的发送，保证配置的PRACH repetition的数量不变。
可选地，所述第一目标RO计入所述PRACH重复传输的RO数量。
该实施例中，在第一目标RO无效时，丢弃该第一目标RO，但是仍对该第一目标RO进行计数。对于仅用于进行PRACH重复传输而单独配置的第一RO，只要公共RO有效(或者公共RO有效但未实际用于PRACH重复传输)，所述第一RO都将映射到公共RO，如果第一RO中的一个或者多个无效，则无效的第一RO丢弃，但仍会计数。其中，所述公共RO为所述PRACH重复传输与PRACH非重复传输使用的公共配置的RO(也可以称为shared RO)。
例如图6所示，所述配置资源包括公共RO和第一RO，公共RO用于进行第一次PRACH repetition，第一RO包括用于PRACH repetition的RO0、RO1、RO2、RO3，且RO0、RO1、RO2、RO3各两个，可以分别进行两次PRACH repetition，其中，1个RO0和1个RO1由于与SSB传输重叠而无效(即图6中右侧的1个RO0和1个RO1为所述第一目标RO)，在没有顺延的情况下被丢弃，则RO0和RO1中的PRACH传输只能重复两次(包括左边的第一次重复)，而RO2和RO3中的PRACH重复传输因为所有RO都有效可以重复3次(包括左边的第一次重复)。
需要说明的是，在所述配置资源中包括公共RO以及第一RO时，公共RO与相应的第一RO关联。例如图5和图6所示，左侧的公共RO中的RO0与右侧的第一RO中的两个RO0关联，左侧的公共RO中的RO1与右侧的两个RO1关联，其他RO以此类推，在此不做赘述。
2)根据所述配置资源中的公共RO的有效性，确定所述配置资源中的第一RO是否用于PRACH重复传输；其中，所述公共RO为所述PRACH重复传输与PRACH非重复传输使用的公共配置的RO；所述第一RO为仅用于PRACH重复传输的RO。
该实施例通过确定公共RO的有效性，确定与该公共RO关联的第一RO的是否实际用于PRACH重复传输。
可选地，所述根据所述配置资源中的公共RO的有效性，确定所述配置资源中的第一RO是否用于PRACH重复传输，包括以下至少一项：
a：若所述公共RO中的第一公共RO无效，则确定与所述第一公共RO关联的第一RO不用于PRACH重复传输。
该实施例中，所述第一公共RO可以是指所述公共RO中的一个或者多个RO，若所述第一公共RO无效，则与所述第一公共RO关联的第一RO被丢弃，不用于PRACH重复传输。
例如图7所示，所述配置资源包括公共RO和第一RO，公共RO用于进行第一次PRACH repetition，第一RO包括用于PRACH repetition的RO0、RO1、RO2、RO3，且RO0、RO1、RO2、RO3各两个，可以分别进行两次PRACH repetition，其中，两个公共RO(左侧的RO2和RO3)与下行链路中由动态授权调度的PDSCH冲突，则与这两个公共RO相关联的额外配置的第一RO(右侧的2个RO2和2个RO3)没有实际传输而被丢弃，且不进行实际的PRACH repetition传输。
b：若所述公共RO中的第一公共RO有效但未用于PRACH重复传输，则确定与所述第一公共RO关联的第一RO不用于PRACH重复传输。
该实施例中，配置资源中的部分公共RO可能有效，但是由于与其他资源冲突或者被配置为不可用，导致该有效的公共RO未用于实际的PRACH重复传输，则与该公共RO关联的第一RO不用于实际的PRACH重复传输。 具体实施例如图7所示，在此不做赘述。
c：若所述公共RO中的第一公共RO无效，则确定与所述第一公共RO关联的第一RO用于PRACH重复传输。
该实施例中，若所述第一公共RO无效，则与所述第一公共RO关联的第一RO仍用于PRACH重复传输。例如图8所示，所述配置资源包括公共RO和第一RO，公共RO用于进行第一次PRACH repetition，第一RO包括用于PRACH repetition的RO0、RO1、RO2、RO3，且RO0、RO1、RO2、RO3各两个，可以分别进行两次PRACH repetition，其中，两个公共RO(左侧的RO2和RO3)与下行链路中由动态授权调度的PDSCH冲突，则与这两个公共RO相关联的额外配置的第一RO(右侧的2个RO2和2个RO3)仍然用于PRACH重复传输，即不丢弃。
d：若所述公共RO中的第一公共RO有效但未用于PRACH重复传输，则确定与所述第一公共RO关联的第一RO用于PRACH重复传输。
该实施例中，若所述第一公共RO有效但是未实际用于PRACH重复传输，则与所述第一公共RO关联的第一RO仍用于PRACH重复传输，例如图8所示，在此不做赘述。
该实施例根据第一RO和/或公共RO的有效性，确定配置资源是否用于实际的PRACH重复传输，例如针对PRACH repetition与其他资源相冲突时，某些PRACH repetition可以被丢弃从而确保其他高优先级的信号可以按时发送或者接收；或者，为了确保实际PRACH repetition的数量，用于repetition的PRACH occasion向后推迟，跳过无效的或者不实际发送PRACH的RO；或者，即便第一次repetition的资源无效或者没有被实际发送PRACH，后续repetition的PRACH资源还可以继续发送剩下的PRACH repetition,降低随机接入的延时。
下面说明根据所述配置资源所在符号的配置信息，确定所述配置资源是否用于PRACH重复传输的具体实现过程。
作为一个可选实施例，所述根据所述配置资源所在符号的配置信息，确定所述配置资源是否用于PRACH重复传输，包括以下至少一项：
A)若第一RO中的第三目标RO所在符号在公共TDD上下行链路配置 信息(tdd-UL-DL-configurationCommon)中配置为灵活符号，在专用TDD上下行链路配置信息(tdd-UL-DL-ConfigurationDedicated)中配置为下行链路，则确定所述第三目标RO不用于PRACH重复传输；其中，所述第一RO为所述配置资源中的仅用于PRACH重复传输的RO。
该实施例中，所述第三目标RO为仅用于进行PRACH重复传输的第一RO中的一个或者多个。如果额外配置的用于发送PRACH repetition的RO(例如所述第一RO中的第三目标RO)所在符号在tdd-UL-DL-configurationCommon中配置为灵活符号(flexible)，在tdd-UL-DL-ConfigurationDedicated中配置为DL，则所述第三目标RO不用于进行PRACH重复传输。
B)若第一RO中的第三目标RO所在符号在公共TDD上下行链路配置信息中配置为灵活符号，在DCI格式中配置为下行链路，则确定所述第三目标RO不用于PRACH重复传输。
该实施例中，所述DCI格式可以为DCI format2-0，如果额外配置的用于发送PRACH repetition的RO(例如所述第一RO中的第三目标RO)所在符号在tdd-UL-DL-configurationCommon中配置为flexible，在DCI format2-0中指示为DL，所述RO不用于PRACH重复传输。
C)若第一RO中的第三目标RO所在符号在第一配置信息中配置为灵活符号，且终端在所述符号上接收下行信号，则确定所述第三目标RO不用于PRACH重复传输。所述第一配置信息包括：公共TDD上下行链路配置信息(tdd-UL-DL-configurationCommon)、专用TDD上下行链路配置信息(tdd-UL-DL-ConfigurationDedicated)以及DCI格式中的至少一项；
该实施例中，所述下行信号例如：PDCCH、PDSCH，所述DCI格式例如DCI format2-0；即如果额外配置的用于发送PRACH repetition的RO(例如所述第一RO中的第三目标RO)所在符号在tdd-UL-DL-configurationCommon和/或tdd-UL-DL-ConfigurationDedicated和/或DCI format2-0中配置为flexible，但是下行信号在上述符号(即RO所在符号)上接收，则该第三目标RO不用于PRACH重复传输。
该实施例基于所述配置资源所在符号的配置信息，确定所述配置信息是 否实际用于PRACH重复传输，给出了UE在不同配置下的传输资源的使用方案，可以保证所述配置资源，降低随机接入的延时。
下面说明根据所述配置资源与其他信号资源的冲突情况，确定所述配置资源是否实际用于PRACH重复传输的实现过程。
作为一个可选实施例，所述根据所述配置资源与其他信号资源的冲突情况，确定所述配置资源是否用于PRACH重复传输，包括以下至少一项：
i)若第一RO中的第四目标RO与随机接入过程中的第一上行信息的传输资源至少部分重叠，则确定所述第四目标RO不用于PRACH重复传输；所述第一RO为所述配置资源中的仅用于PRACH重复传输的RO。
所述第四目标RO可以为仅用于进行PRACH重复传输的第一RO中的一个或者多个RO。所述第一上行信息可以为随机接入过程的MsgA。即：对于额外配置的用于发送PRACH重复的RO(例如所述第四目标RO)，如果RO与MsgA PUSCH传输至少部分重叠，则该RO不用于PRACH重复发送。
该实施例中，由于不支持PRACH重复的UE可能不会读取和识别额外配置的用于发送PRACH重复的ROs，这意味着MsgA PUSCH必须优先于为PRACH重复配置的单独ROs，即MsgA PUSCH优先于所述第四目标RO的传输。另一方面，在第四目标RO和MsgA PUSCH的资源存在重叠时，丢弃部分PRACH重复，保护MsgA PUSCH，可能不会导致PRACH接收失败，但可以确保MsgA PUSCH的及时发送。
ii)若高层信令指示终端在时隙内的一组符号中接收下行信号，DCI格式信息指示终端在第四目标RO进行PRACH重复传输，且所述第四目标RO与所述时隙所在的符号集合中的至少一个符号重叠，则确定所述第四目标RO不用于PRACH重复传输。
该实施例中，对于在未配对频谱中的单个载波上的操作，如果UE由高层配置在时隙内的一组符号中接收PDCCH、PDSCH、CSI-RS或DL PRS等下行信号，则UE接收PDCCH、PDSCH、CSI-RS或者DL PRS等下行信号，即使UE检测到DCI格式，该DCI格式指示UE在一个额外配置的RO(例如第四目标RO)发送PRACH重复，并且该额外配置的RO(例如第四目标RO)与该时隙的符号集合的至少一个符号重叠，UE不在所述第四目标RO 上进行PRACH重复传输，而是在所述时隙的符号上接收下行信号。
该实施例中，下行信号接收的优先级高于PRACH重复传输，相关协议可以引用相应修改，例如：
对于在未配对频谱中的单个载波上的操作，如果UE由高层配置在时隙内的一组符号中接收PDCCH、PDSCH、CSI-RS或DL PRS等下行信号，如果UE未检测到指示UE在时隙的符号集合的至少一个符号中发送PUSCH、PUCCH、PRACH非重复或SRS的DCI格式，则UE接收PDCCH、PDSCH、CSI-RS或DL-PRS；否则，如果UE未检测到指示UE发送重复的PRACH的DCI格式，则UE不接收时隙的符号集合中的PDCCH、PDSCH、CSI-RS或DL-PRS等下行信号。(For operation on a single carrier in unpaired spectrum，if a UE is configured by higher layers to receive a PDCCH，or a PDSCH，or a CSI-RS，or a DL PRS in a set of symbols of a slot，the UE receives the PDCCH，the PDSCH，the CSI-RS，or the DL PRS if the UE does not detect a DCI format that indicates to the UE to transmit a PUSCH，a PUCCH，a PRACH without repetition，or a SRS in at least one symbol of the set of symbols of the slot；otherwise and if the UE does not detect a DCI format that indicates to the UE to transmit a PRACH with repetition，the UE does not receive the PDCCH，or the PDSCH，or the CSI-RS，or the DL PRS in the set of symbols of the slot)。
iii)若高层信令指示终端在第四目标RO上的目标符号中进行PRACH重复传输，DCI格式信息指示终端在所述目标符号的符号子集中接收下行信号，则所述第四目标RO不用于PRACH重复传输。
该实施例中，对于在未配对频谱中的单个载波上的操作，如果UE由高层配置为在额外配置的RO(例如第四目标RO)上对应某个时隙的一组符号中发送PRACH重复，并且UE检测到DCI格式，该DCI格式指示UE从该组符号中接收符号子集中的下行信号(例如CSI-RS或PDSCH)，则UE不在第四目标RO进行PRACH重复传输，而是在所述目标符号的子集中接收下行信号。可选地，所述第四目标RO不用于PRACH重复传输，但仍对相应的PRACH重复进行计数。
该实施例根据所述配置资源与其他信号资源的冲突情况，确定所述配置 资源是否用于PRACH重复传输，针对PRACH repetition与其他资源相冲突时，某些PRACH repetition可以被丢弃从而确保其他高优先级的信号可以按时发送或者接收，降低随机接入的延时。
作为一个可选实施例，所述方法还包括：确定所述PRACH重复传输的功率分配优先级；
所述功率分配优先级包括以下至少一项：
1)进行重复传输的PRACH的功率分配优先级低于在主小区(PCell)上不做重复传输的PRACH的功率分配优先级。
该实施例中，基于本实施列，重复传输的PRACH相对于在载波聚合过程中同时发送的其他上行信号，会被低优先级的分配功率，相关协议可以引入相应修改，例如：
时隙符号中的总UE发射功率被定义为时隙符号中PUSCH、PUCCH、PRACH和SRS的UE发射功率的线性值之和(The total UE transmit power in a symbol of a slot is defined as the sum of the linear values of UE transmit powers for PUSCH，PUCCH，PRACH，and SRS in the symbol of the slot)。
在Pcell上不进行PRACH重复传输(PRACH transmission without repetition on the Pcell)；
具有更高优先级索引的PUCCH或PUSCH传输(PUCCH or PUSCH transmissions with higher priority index according to clause 9)；
对于具有相同优先级索引的PUCCH或PUSCH传输(For PUCCH or PUSCH transmissions with same priority index)；
带有混合自动重传请求应答(Hybrid automatic repeat request acknowledgement，HARQ-ACK)信息的PUCCH传输，和/或调度请求(Scheduling Request，SR)，和/或链路恢复请求(Link recovery request，LRR)，或带有HARQ-ACK信息的PUSCH传输(PUCCH transmission with HARQ-ACK information，and/or SR，and/or LRR，or PUSCH transmission with HARQ-ACK information)；
带有CSI的PUCCH传输或带有CSI的PUSCH传输(PUCCH transmission with CSI or PUSCH transmission with CSI)；
没有HARQ-ACK信息或CSI的PUSCH传输，对于Type-2随机接入过程，Pcell上的PUSCH传输(PUSCH transmission without HARQ-ACK information or CSI and，for Type-2 random access procedure，PUSCH transmission on the Pcell)；
SRS传输，具有比半持续和/或周期SRS具有更高优先级的非周期SRS，或在除Pcell或PRACH重复传输之外的服务小区上的PRACH传输(SRS transmission，with aperiodic SRS having higher priority than semi-persistent and/or periodic SRS，or PRACH transmission on a serving cell other than the Pcell or PRACH repetition transmissions)。
2)进行重复传输的PRACH的功率分配优先级，与在主小区上不做重复传输的PRACH的功率分配优先级相同。
该实施例中，重复的PRACH相对于在载波聚合过程中同时发送的其他上行信号，会被高优先级的分配功率。相关协议可以引入相应修改，例如：
时隙符号中的总UE发射功率被定义为时隙符号中PUSCH、PUCCH、PRACH和SRS的UE发射功率的线性值之和(The total UE transmit power in a symbol of a slot is defined as the sum of the linear values of UE transmit powers for PUSCH，PUCCH，PRACH，and SRS in the symbol of the slot)。
Pcell上的PRACH传输或PRACH重复传输(PRACH transmission on the Pcell or PRACH repetition transmission)；
具有更高优先级索引的PUCCH或PUSCH传输(PUCCH or PUSCH transmissions with higher priority index according to clause 9)；
对于具有相同优先级索引的PUCCH或PUSCH传输(For PUCCH or PUSCH transmissions with same priority index)；
带有HARQ-ACK信息的PUCCH传输，和/或SR，和/或LRR，或带有HARQ-ACK信息的PUSCH传输(PUCCH transmission with HARQ-ACK information，and/or SR，and/or LRR，or PUSCH transmission with HARQ-ACK information)；
带有CSI的PUCCH传输或带有CSI的PUSCH传输(PUCCH transmission with CSI or PUSCH transmission with CSI)；
没有HARQ-ACK信息或CSI的PUSCH传输，对于Type-2随机接入过程，Pcell上的PUSCH传输(PUSCH transmission without HARQ-ACK information or CSI and，for Type-2 random access procedure，PUSCH transmission on the Pcell)；
SRS传输，非周期SRS具有比半持续和/或周期SRS更高的优先级，或者在除Pcell以外的服务小区上进行PRACH传输(SRS transmission,with aperiodic SRS having higher priority than semi-persistent and/or periodic SRS,or PRACH transmission on a serving cell other than the Pcell)。
3)若在主小区上进行所述PRACH重复传输，则重复传输的PRACH的功率分配优先级，与在主小区上不做重复传输的PRACH的功率分配优先级相同；
4)若在非主小区上进行所述PRACH重复传输，则重复传输的PRACH的功率分配优先级，与在非主小区上不做重复传输的PRACH的功率分配优先级相同；
5)进行重复传输的PRACH的功率分配优先级，与在非主小区上不做重复传输的PRACH的功率分配优先级相同。
该实施例通过定义所述PRACH重复传输的功率分配优先级，确保具有高优先级的信号可以按时发送或者接收，保证信号传输正常进行。
作为一个可选实施例，所述PRACH重复传输在第一持续时间内完成；
所述第一持续时间包括以下至少一项：
SSB至RO的映射周期的M倍时间；
SSB至RO的映射关联周期的N倍时间；
SSB至RO的关联模式周期的L倍时间；
随机接入响应窗口对应的时间值；所述随机接入响应窗口的最大值可以为10ms；
SSB至PRACH重复传输的RO的关联模式周期；所述SSB至PRACH重复传输的RO的关联模式周期可以是针对PRACH重复传输额外配置的。
其中，M、N、L为正整数。所述M、N、L的具体数值可以由协议定义或者由系统消息配置。
该实施例中，额外的定义SSB到PRACH重复传输的RO关联模式周期，其可以包括一个或多个SSB到RO关联模式周期，使得PRACH重复RO和SSB之间的模式最多可以在每个预定时间周期(例如，每640ms)重复。可选地，所述预定时间周期可以是SSB到(现有的、单次发送的)PRACH的RO关联模式周期的正整数倍。
例如图9所示，配置了4次重复传输的RO，前3次重复传输在SSB到RO的关联模式周期内，但第4次重复出现在下一个SSB到RO的关联模式周期内，那么第4次重复将被丢弃。需要说明的是，图9中的RO表示为所述PRACH重复传输配置的RO，可以是公共RO也可以为第一RO，在此不做限定。
可选地，若配置的所述PRACH重复传输未在上述第一持续时间内完成，则剩余次数的PRACH重复传输可以全部丢弃，也可以在第一持续时间结束之前完成部分发送。
本申请实施例，终端获取针对PRACH重复传输的配置资源，并确定所述配置资源是否实际用于PRACH重复传输，提供了配置资源无效或者与其他信号资源冲突时的解决方案，能够降低随机接入延时。例如：针对PRACH repetition与其他资源相冲突时，部分PRACH repetition可以被丢弃或者不增加发送功率从而确保其他高优先级的信号可以按时发送或者接收；或者，为了确保实际PRACH repetition的数量，用于repetition的PRACH occasion需要向后推迟，跳过无效的或者不实际发送PRACH的RO；或者，即使第一次repetition的资源无效或者没有被实际发送PRACH，后续repetition的PRACH资源还可以继续发送剩下的PRACH repetition，降低随机接入的延时。
如图10所示，本申请实施例还提供一种确定PRACH重复传输资源的方法，应用于网络侧设备，包括：
步骤101、网络侧设备确定PRACH重复传输的配置资源；
步骤102、所述网络侧设备确定所述配置资源是否用于接收重复传输的PRACH。
该实施例中，所述PRACH重复传输与PRACH重传的定义不同，本申请实施例的PRACH重复是指在每次PRACH初传或者重传过程中做的重复传输， PRACH重复只发生在随机接入响应窗口结束之前。
网络侧设备为终端配置PRACH重复传输的资源。所述配置资源是指网络侧设备为终端配置的用于PRACH repetition传输的资源，并不一定是终端进行PRACH repetition传输实际使用的传输资源。PRACH repetition的资源指用于发送PRACH repetition的PRACH资源；不支持PRACH repetition的PRACH资源指用于发送PRACH但是没有做repetition的PRACH资源。PRACH资源可以是PRACH时频资源和/或PRACH序列
终端确定所述配置资源是否实际用于PRACH重复传输，并在实际传输的配置资源上进行PRACH重复传输；则网络侧设备也需要基于和终端相应的规则确定配置资源是否实际用于PRACH重复传输，并在实际传输的配置资源上接收重复传输的PRACH。
本申请的实施例，网络侧设备针对PRACH重复传输配置资源，并确定配置的资源是否实际用于PRACH重复传输，使网络侧设备可以在实际用于PRACH重复传输的配置资源上接收重复传输的PRACH，能够降低随机接入延时。
可选地，所述方法还包括：向终端发送针对PRACH重复传输的资源配置信息，所述资源配置信息指示所述配置资源。
该实施例中，网络侧设备配置了针对PRACH重复传输的配置资源后，可以通过资源配置信息将所述配置资源发送至所述终端，以使所述终端确定所述配置资源是否实际用于PRACH重复传输，从而确定配置资源无效或者与其他信号资源冲突时的解决方案，降低随机接入延时。
可选地，所述确定所述配置资源是否用于接收重复传输的PRACH，包括以下至少一项：
(1)根据所述配置资源的有效性，确定所述配置资源是否用于接收重复传输的PRACH；
(2)根据所述配置资源所在符号的配置信息，确定所述配置资源是否用于接收重复传输的PRACH；
(3)根据所述配置资源与其他信号资源的冲突情况，确定所述配置资源是否用于接收重复传输的PRACH。
该实施例中，终端可以根据配置资源的有效性、配置资源所在符号的配置信息、配置资源与其他信号资源的冲突情况中的一种或者多种方式的组合，确定配置资源是否能够实际用于PRACH重复传输。可选地，在根据所述配置资源的有效性确定所述配置资源是否用于接收重复传输的PRACH时，所述方法还可以包括：
确定所述配置资源的有效性；其中，所述配置资源的有效性，与第一间隙要求和/或时分复用TDD上下行链路配置相关；所述第一间隙要求为SSB传输、用于SSB传输的符号集、用于PRACH传输的符号集三者之间的间隙要求。
该实施例中，在基于配置资源的有效性确定是否接收重复传输的PRACH时，配置资源验证有效性的方法可以与现有技术中不进行重复传输的PRACH资源的有效性验证方法相同，即配置资源是否有效取决于SSB传输、用于SSB传输的符号集和用于RPACH传输的符号集之间的间隙要求以及小区特定的TDD上行链路-下行链路配置。
可选地，对于可以同时发送PRACH重复传输和PRACH非重复传输的公共配置的资源，配置资源的有效性验证规则在两种PRACH传输情况下应相同，因此可以使用PRACH非重复传输的验证规则验证本申请实施例中的配置资源的有效性。确定所述配置资源的有效性的方式在此不做限定。
下面通过具体实施例说明通过上述三种方式确定所述配置资源是否用于接收重复传输的PRACH的具体实现过程
作为一个可选实施例，所述根据所述配置资源的有效性，确定所述配置资源是否用于接收重复传输的PRACH，包括以下至少一项：
1)根据所述配置资源中的第一RO的有效性，确定所述配置资源是否用于接收重复传输的PRACH。
所述配置资源中包括针对PRACH重复传输配置的RO资源。所述第一RO为仅用于PRACH重复传输的RO，所述第一RO可以包括一个或者多个RO。该实施例根据额外配置的仅用于进行PRACH重复传输的RO的有效性，确定该RO是否能够实际用于PRACH重复传输，即网络侧设备是否需要在该第一RO上接收重复传输的PRACH。
可选地，所述根据所述配置资源中的第一RO的有效性，确定所述配置资源是否用于接收重复传输的PRACH，包括：若所述第一RO中的第一目标RO无效，则确定所述第一目标RO不用于接收PRACH重复传输。所述第一RO为仅用于PRACH重复传输的RO。
该实施例中，所述第一目标RO可以是指所述第一RO中的一个或者多个RO，对于仅用于进行PRACH重复传输的RO，若该RO无效，则该RO被丢弃，不能用于进行PRACH重复传输。其中，在第一目标RO无效被丢弃时，可以不对该第一目标RO进行计数，也可以对该第一目标RO进行计数。下面分别说明。
可选地，所述方法还包括：确定第二目标RO的时域位置，所述第二目标RO是将所述第一目标RO推迟一个RO级别的时域位置获得，所述第二目标RO用于接收重复传输的PRACH。
该情况下，在第一目标RO无效时，不对该第一目标RO进行计数，可以将无效的第一目标RO推迟，获得新的有效的第二目标RO，从而确保有效的PRACH repetition数量。例如图5所示，在此不做赘述。
可选地，所述第一目标RO计入所述PRACH重复传输的RO数量。该实施例中，在第一目标RO无效时，丢弃该第一目标RO，但是仍对该第一目标RO进行计数。对于仅用于进行PRACH重复传输而单独配置的第一RO，只要公共RO有效(或者公共RO有效但未实际用于PRACH重复传输)，所述第一RO都将映射到公共RO，如果第一RO中的一个或者多个无效，则无效的第一RO丢弃，但仍会计数，例如图6所示，在此不做赘述。
2)根据所述配置资源中的公共RO的有效性，确定所述配置资源是否用于接收重复传输的PRACH；其中，所述公共RO为所述PRACH重复传输与PRACH非重复传输使用的公共配置的RO。
该实施例通过确定公共RO的有效性，确定与该公共RO关联的第一RO的是否用于接收重复传输的PRACH。
可选地，所述根据所述配置资源中的公共RO的有效性，确定所述配置资源是否用于接收重复传输的PRACH，包括以下至少一项：
a：若所述公共RO中的第一公共RO无效，则确定与所述第一公共RO 关联的第一RO不用于接收重复传输的PRACH。
该实施例中，所述第一公共RO可以是指所述公共RO中的一个或者多个RO，若所述第一公共RO无效，则与所述第一公共RO关联的第一RO被丢弃，不用于PRACH重复传输，则网络侧设备不需要在所述第一公共RO关联的第一RO中接收重复传输的PRACH。
b：若所述公共RO中的第一公共RO有效但未用于PRACH重复传输，则确定所与所述第一公共RO关联的第一RO不用于接收重复传输的PRACH。
该实施例中，配置资源中的部分公共RO可能有效，但是由于与其他资源冲突或者被配置为不可用，导致该有效的公共RO未用于实际的PRACH重复传输，则与该公共RO关联的第一RO不用于实际的PRACH重复传输，则与所述第一公共RO关联的第一RO不用于接收重复传输的PRACH。
c：若所述公共RO中的第一公共RO无效，则确定与所述第一公共RO关联的第一RO用于接收重复传输的PRACH。
该实施例中，若所述第一公共RO无效，则与所述第一公共RO关联的第一RO仍用于PRACH重复传输，则与所述第一公共RO关联的第一RO仍用于接收重复传输的PRACH。
d：若所述公共RO中的第一公共RO有效但未用于PRACH重复传输，则确定与所述第一公共RO关联的第一RO用于接收重复传输的PRACH。
该实施例中，若所述第一公共RO有效但是未实际用于PRACH重复传输，则与所述第一公共RO关联的第一RO仍用于PRACH重复传输，则与所述第一公共RO关联的第一RO仍用于接收重复传输的PRACH。
该实施例根据第一RO和/公共RO的有效性，确定配置资源是否用于实际的PRACH重复传输，例如针对PRACH repetition与其他资源相冲突时，某些PRACH repetition可以被丢弃从而确保其他高优先级的信号可以按时发送或者接收；或者，为了确保实际PRACH repetition的数量，用于repetition的PRACH occasion向后推迟，跳过无效的或者不实际发送PRACH的RO；或者，即便第一次repetition的资源无效或者没有被实际发送PRACH，后续repetition的PRACH资源还可以继续发送剩下的PRACH repetition,降低随机接入的延时。
下面说明根据所述配置资源所在符号的配置信息，确定所述配置资源是否用于接收重复传输的PRACH的具体实现过程。
作为一个可选实施例，所述根据所述配置资源所在符号的配置信息，确定所述配置资源是否用于接收重复传输的PRACH，包括以下至少一项：
A)若第一RO中的第三目标RO所在符号在公共TDD上下行链路配置信息中配置为灵活符号，在专用TDD上下行链路配置信息中配置为下行链路，则确定所述第三目标RO不用于接收重复传输的PRACH。其中，所述第一RO为所述配置资源中的仅用于PRACH重复传输的RO。
该实施例中，所述第三目标RO为仅用于进行PRACH重复传输的第一RO中的一个或者多个。如果额外配置的用于发送PRACH repetition的RO(例如所述第一RO中的第三目标RO)所在符号在tdd-UL-DL-configurationCommon中配置为灵活符号(flexible)，在tdd-UL-DL-ConfigurationDedicated中配置为DL，则所述第三目标RO不用于进行PRACH重复传输，则所述网络侧设备在所述第三目标RO上接收重复传输的PRACH。
B)若第一RO中的第三目标RO所在符号在公共TDD上下行链路配置信息中配置为灵活符号，在DCI格式中配置为下行链路，则确定所述第三目标RO不用于接收重复传输的PRACH。
该实施例中，所述DCI格式可以为DCI format2-0，如果额外配置的用于发送PRACH repetition的RO(例如所述第一RO中的第三目标RO)所在符号在tdd-UL-DL-configurationCommon中配置为flexible，在DCI format2-0中指示为DL，所述第三目标RO不用于PRACH重复传输，则所述第三目标RO不用于接收重复传输的PRACH。
C)若第一RO中的第三目标RO所在符号在第一配置信息中配置为灵活符号，且终端在所述符号上接收下行信号，则确定所述第三目标RO不用于接收重复传输的PRACH；所述第一配置信息包括：公共TDD上下行链路配置信息、专用TDD上下行链路配置信息以及DCI格式中的至少一项；其中，所述第一RO为所述配置资源中的仅用于PRACH重复传输的RO。
该实施例中，所述下行信号例如：PDCCH、PDSCH，所述DCI格式例 如DCI format2-0；即如果额外配置的用于发送PRACH repetition的RO(例如所述第一RO中的第三目标RO)所在符号在tdd-UL-DL-configurationCommon和/或tdd-UL-DL-ConfigurationDedicated和/或DCI format2-0中配置为flexible，但是下行信号在上述符号(即RO所在符号)上接收，则该第三目标RO不用于PRACH重复传输，则所述第三目标RO不用于接收重复传输的PRACH。
该实施例基于所述配置资源所在符号的配置信息，确定所述配置信息是否实际用于PRACH重复传输，给出了UE在不同配置下的传输资源的使用方案，可以保证所述配置资源，降低随机接入的延时。
下面说明根据所述配置资源与其他信号资源的冲突情况，确定所述配置资源是否实际用于PRACH重复传输的实现过程。
作为一个可选实施例，根据所述配置资源与其他信号资源的冲突情况，确定所述配置资源是否用于接收重复传输的PRACH，包括：
若第一RO中的第四目标RO与随机接入过程中的第一上行信息的传输资源至少部分重叠，则确定所述第四目标RO不用于接收重复传输的PRACH。
所述第四目标RO可以为仅用于进行PRACH重复传输的第一RO中的一个或者多个RO。所述第一上行信息可以为随机接入过程的MsgA。即：对于额外配置的用于发送PRACH重复的RO(例如所述第四目标RO)，如果RO与MsgA PUSCH传输至少部分重叠，则该RO不用于PRACH重复发送，则该RO不用于接收重复传输的PRACH。
该实施例中，由于不支持PRACH重复的UE可能不会读取和识别额外配置的用于发送PRACH重复的ROs，这意味着MsgA PUSCH必须优先于为PRACH重复配置的单独ROs，即MsgA PUSCH优先于所述第四目标RO的传输。另一方面，在第四目标RO和MsgA PUSCH的资源存在重叠时，丢弃部分PRACH重复，保护MsgA PUSCH，可能不会导致PRACH接收失败，但可以确保MsgA PUSCH的及时发送。
可选地，若高层信令指示终端在时隙内的一组符号中接收下行信号，DCI格式信息指示终端在第四目标RO进行PRACH重复传输，且所述第四目标RO与所述时隙所在的符号集合中的至少一个符号重叠，则所述第四目标RO 不用于PRACH重复传输。若所述高层信令将对于终端的指示信息通知网络侧设备，例如通知网络侧设备终端在所述符号内接收下行信号，则网络侧设备结合DCI格式信息可以确定所述第四目标RO不用于接收重复传输的PRACH。
可选地，若高层信令指示终端在第四目标RO上的目标符号中进行PRACH重复传输，DCI格式信息指示终端在所述目标符号的符号子集中接收下行信号，则所述第四目标RO不用于PRACH重复传输。若所述高层信令将对于终端的指示信息通知网络侧设备，例如通知网络侧设备终端在第四目标RO上的目标符号中进行PRACH重复传输，则网络侧设备结合DCI格式信息可以确定，所述第四目标RO不用于接收重复传输的PRACH。
该实施例根据所述配置资源与其他信号资源的冲突情况，确定所述配置资源是否用于PRACH重复传输，针对PRACH repetition与其他资源相冲突时，某些PRACH repetition可以被丢弃从而确保其他高优先级的信号可以按时发送或者接收，降低随机接入的延时。
可选地，所述网络侧设备还可以确定PRACH重复传输的功率分配优先级，所述功率分配优先级包括以下至少一项：
1)进行重复传输的PRACH的功率分配优先级低于在主小区(PCell)上不做重复传输的PRACH的功率分配优先级。
2)进行重复传输的PRACH的功率分配优先级，与在主小区上不做重复传输的PRACH的功率分配优先级相同。
3)若在主小区上进行所述PRACH重复传输，则重复传输的PRACH的功率分配优先级，与在主小区上不做重复传输的PRACH的功率分配优先级相同；
4)若在非主小区上进行所述PRACH重复传输，则重复传输的PRACH的功率分配优先级，与在非主小区上不做重复传输的PRACH的功率分配优先级相同；
5)进行重复传输的PRACH的功率分配优先级，与在非主小区上不做重复传输的PRACH的功率分配优先级相同。
该实施例通过定义所述PRACH重复传输的功率分配优先级，确保具有 高优先级的信号可以按时发送或者接收，保证信号传输正常进行。
可选地，所述PRACH重复传输的接收在第一持续时间内完成；
所述第一持续时间包括以下至少一项：
