To avoid redundancy, the following description will use the validity period as the activation validity period of the attached PRACH resource. It can be understood that the terminal considers the attached PRACH resource outside its validity period to be deactivated. If the validity period is the deactivation validity period of the attached PRACH resource, then the terminal considers the attached PRACH resource outside its validity period to be active.
  • the update information of the activation validity period of the additional PRACH resource is used to indicate whether the activation validity period of the additional PRACH resource should be reset.
  • the activation or deactivation related information indicates the expiration date reset of the activation of the additional PRACH resource associated with the first bit.

It can be understood that, based on this activation or deactivation information, the terminal can determine that the validity period of the attached PRACH resource activation has been updated, i.e., updated to the first validity period. Simultaneously, the terminal can also determine the start and end times of the associated attached PRACH resource activation or deactivation based on this validity period reset information. Correspondingly, the terminal can also determine which attached PRACH resources are activated or deactivated.

  • the activation or deactivation related information indicates that the validity period of the activation of the additional PRACH resource associated with the first bit decreases.
  • the activation or deactivation information indicating a decrease in the validity period of the attached PRACH resource activation can be understood as: the activation or deactivation information indicates that the assumptions regarding the activation or deactivation of the attached PRACH resource remain unchanged (e.g., the assumption that the validity period of activation remains unchanged). It can be understood that, based on this activation or deactivation information, the terminal can determine that the length or range of the validity period of the attached PRACH resource activation has not changed. Simultaneously, the terminal can also determine that the start and end times of the associated attached PRACH resource activation or deactivation have not changed.

  • the terminal when the bit associated with the additional PRACH resource indicates the second value, the terminal considers the additional PRACH resource temporarily deactivated. At this time, the validity period is paused and does not decrease until the first indication information indicates the first value again, or the validity period is reconfigured. It is understandable that based on this activation or deactivation information, the terminal can determine that the validity period or time range of the activated additional PRACH resource has been updated because the end time of activation or deactivation has changed. Simultaneously, the terminal can also determine which additional PRACH resources are activated or deactivated.
  • the terminal considers the additional PRACH resource temporarily deactivated, and at this time, the validity period decreases normally; that is, the validity period decreases over time regardless of whether the associated additional PRACH resource is activated or deactivated. It is understandable that based on this activation or deactivation information, the terminal can determine that the validity period or time range of the activated additional PRACH resource has not been updated. However, at this time, which additional PRACH resources within the validity period are activated or deactivated has changed, and the terminal can determine this information.
  • the activation or deactivation related information indicates that the validity period of the activation of the additional PRACH resource associated with the second bit and the first bit decreases. It can be understood that, based on this activation or deactivation related information, the terminal can determine that the duration or range of the activation validity period of the additional PRACH resource has not changed. Simultaneously, the terminal can also determine that the start and end times of the activation or deactivation of the associated additional PRACH resource have not changed. Correspondingly, the terminal can also determine which additional PRACH resources are activated or deactivated as the time unit decreases.
  • the attached PRACH resource is associated with two bits: one bit indicates whether the expiration date has been reset, and the other bit indicates whether the expiration date has been decremented. Compared to the method of using only one bit to indicate whether the expiration date has been reset, this avoids the terminal being unable to determine whether the attached PRACH resource is activated when it has not received any indication information.
  • the activation or deactivation related information indicates that the validity period of the activation of the additional PRACH resource associated with the second bit and the first bit is suspended. It can be understood that, based on this activation or deactivation related information, the terminal can determine that the duration or range of the validity period of the activation of the additional PRACH resource has been updated because the end time of activation or deactivation has changed. Correspondingly, the terminal also needs to re-determine whether the additional PRACH resource is activated or not.
  • whether the validity period decreases can also refer to whether the validity period is suspended. That is, the validity period not decreasing is equivalent to the validity period being suspended, and the validity period decreasing is equivalent to the validity period not being suspended. It can be understood that the validity period decreasing means that the associated additional PRACH resource is considered to be active, and the validity period being suspended means that the associated additional PRACH resource is considered to be deactivated.
  • the first bit is used to determine whether the validity period of the activation of the additional PRACH resource associated with the bit is reduced or suspended; the second bit is used to determine whether the validity period of the activation of the additional PRACH resource associated with the bit is reset.

  • the validity period of the activation of the additional PRACH resource associated with the first bit is reduced.
  • the additional PRACH resources associated with each bit are configured by the network-side device. That is, the additional PRACH resources associated with each indication bit are determined and are unrelated to whether or not the first indication information is received. Therefore, even if the first indication information is not received, the above activation or deactivation related information can indicate that the validity period of the activation of the additional PRACH resources associated with the first bit is decreasing. In other words, the terminal believes that the validity period of the activation of the additional PRACH resources associated with the first bit is decreasing.
  • the activation or deactivation related information indicates that the additional PRACH resource associated with the first bit is deactivated until an indication that the first bit is the first value is received. It can be understood that, at this time, as long as an indication that the first bit is the second value is received, the associated PRACH resource is considered deactivated.
  • the activation validity period of the additional PRACH resource associated with the first bit of the activation or deactivation related information indication does not decrease until an indication that the first bit is a first value is received. It can be understood that when the first bit is a second value, the validity period is suspended until the first bit is a first value.
  • whether to deactivate the additional PRACH resource or reduce its validity period in the absence of the first indication information is determined based on the previously received indication information. It is understood that when the terminal fails to receive the first indication information for various reasons, it determines the activation or deactivation information of the additional PRACH resource based on previously received indication information. For example, if the previously received indication information indicated that some additional PRACH resources were active, they are still considered active; or, if the previously received indication information indicated that the validity period was decreasing normally, the validity period is also considered to be decreasing normally.
  • the activation or deactivation related information indicates that the additional PRACH resource in the first time window is activated.
  • the first time window is the current period within the validity period or at least one period after the current period within the validity period.
  • the terminal might not have received the relevant signaling for validity period settings or updates.
  • it's necessary to determine whether subsequent additional PRACH resources are activated Since it's certain that the current validity period is within the specified timeframe, the terminal, based on this information, considers the additional PRACH resources within the first time window to be activated.
  • the network-side device periodically sends the first indication information. If the terminal has received a first indication information where the first bit has the second value, and has not received another first indication information where the first bit has the first value, the terminal will activate or deactivate the relevant information indicating that the additional PRACH resource within the first time window is active. It can be understood that when the first bit has the second value, it indicates that the activation validity period is decreasing normally. Therefore, even if the terminal has not received a first indication information indicating that the validity period has taken effect, it can at least determine that the additional PRACH resource is active within the current validity period.
  • the above-mentioned activation or deactivation related information indicates that the additional PRACH resources within the first time window are activated.
  • the terminal if a first indication message with the first bit having the first value has been received within the second time window, the terminal considers the additional PRACH resource within the first time window to be active when a first indication message with the first bit having the second value is received.

背景技术
网络节能对于环境可持续性、减少环境影响以及操作成本节省具有重要意义。随着5G在各个行业和地区变得普及，处理需要非常高的数据速率的更高级服务和应用程序，网络变得更加密集，使用更多天线、更大的带宽和更多频带。5G的环境影响需要保持在控制之下，并且需要开发新的解决方案来提高网络节能。
目前无线接入的功耗可以分为两部分：动态部分仅在进行数据发送或接收时消耗，静态部分则是始终消耗以维持无线接入设备的运行所需，即使当数据发送或接收未正在进行时也是如此。因此如何最大限度减少静态部分的功耗是需要解决的技术问题。例如对于随机接入过程，在小区的终端数量不断变化，发起随机接入的终端数量也不断变化的情况下，由于物理随机接入信道(Physical Random Access Channel，PRACH)资源是通过系统信息配置的，更新的频率较慢，因此维持一个相对固定的PRACH资源配置，则需要基站总是在这些资源上不断的检测是否有终端执行随机接入流程，因此不利于网络节能。如此，如何配置PRACH资源，以提高网络节能的效果是需要解决的技术问题。

下面对本申请实施例提供的资源确定方法、装置、设备及存储介质中涉及的一些概念和/或术语做一下解释说明。
1、同步信号块(Synchronization Signal Block，SSB)
终端先检测NR主同步信号(Primary Synchronization Signal，PSS)检测，获得物理小区标识的一部分，即N(2)_ID；获得正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号定时和频率同步；再检测辅同步信号(Secondary Synchronization Signal，SSS)，获得物理小区ID的另一部分，即N(1)_ID，得到完整的物理小区标识。
然后终端检测物理广播信道(Physical Broadcast Channel，PBCH)和解调PBCH的解调参考信号(Demodulation Reference Signal，DMRS)，得到系统帧号(System Frame Number，SFN)和SSB索引，进一步得到无线帧(subframe)定时。
NR中SSB周期会在系统信息块1(System Information Block，SIB1)中配置，可能是5、10、20、40、80、160ms，在初始接入的时候，终端还没有接收到SIB1，则会按照默认的20ms周期来搜索SSB。SSB并不是隔一段时间出现一次，而是隔一段时间在某一个半帧内出现若干次，这个就是为了波束扫描而设计的，这若干个SSB中每个都对应一个波束扫描的方向，最终每个方向都会有一个SSB，这若干个SSB就叫一个SSB set，一个SSB set中的所有SSB都要在同一个半帧内。
2、多载波场景下的SSB发送方法
多载波是5G NR网络的典型操作，用以增强网络侧容量。对于Pcell或PScell，基站必须发送周期性的SSB，并且SSB周期需要小于等于20ms才能被初搜的终端搜索成功。
对于intra-band的Scell，基站可以发送SSB，此时在添加该Scell时配置SSB相关参数；也可以不发送SSB，此时在添加该Scell时不配置SSB相关参数，终端通过Pcell上的SSB获取timing。
对于inter-band的Scell，基站必须发送SSB，并且在在添加该Scell时配置SSB相关参数。
3、5G NR中SSB到随机接入信道时机(Random Access Channel Occasion，RO)的映射规则
PRACH资源以及SSB-RO的配置参数在系统信息块SIB1中配置。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 Multiplexing，FDM)的PRACH传输机会(transmission occasion，又或者称为PRACH Occasion，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}，其通过高层参数msg1-FDM来配置确定。
随机接入前导码(Preamble)只能在参数PRACHConfigurationIndex配置的时域资源上和参数msg1-FDM配置的频域资源上传输。PRACH频域资源nRA∈{0,1,...,M-}1，其中M等于高层参数msg1-FDM。在初始接入的时候，PRACH频域资源nRA从初始激活上行带宽部分(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nRA从激活上行带宽部分(active uplink bandwidth part)内频率最低RO资源开始升序编号。例如一个时刻FDM的RO个数为8(msg1-FDM＝8)，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。RO按照先频域(从低频到高频)再时域的顺序关联到SSB。一个SSB可能关联多个连续的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)，其由网络通过参数ssb-perRACH-OccasionAndCB-PreamblesPerSSB来配置。
所有SSB关联完RO一轮后构成一个SSB-RO映射周期(SSB-RO mapping cycle)。一个SSB到RO的关联期(association period)可能包含1个或多个SSB-RO映射周期。一个SSB到RO的关联模式周期(association pattern period)可能包含一个或多个SSB-RO关联期，SSB到RO的映射以关联模式周期为周期进行重复，关联模式周期最大为160ms。
通常，基站可以采用不同的波束进行不同的SSB的发送，其中SSB的数量通过ssb-PositionsInBurst参数来配置，对于FR2(Frequency Range 2)，最大SSB数量为64。终端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，网络就可以根据接收到的Preamble的RO/"RO和preamble组合"，确定出终端所选择的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。
例如，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。如果终端确定在SSB#0对应的RO上发送PRACH/Msg1，那么终端在RO#0和RO#1中选择一个RO进行PRACH的发送。
又例如，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不能同时归属不同SSB关联的Preamble集合：以RO#0为例，RO#0共有60个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。
终端发送PRACH前，首先根据接收到的波束(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；当没有RSRP高于门限的SSB，终端基于实现选择一个SSB。
基于网络的配置，终端获得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/Msg1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/Msg1的发送。
例如，假设终端选择了SSB#1，终端可以从RO#2和RO#3中选择一个进行PRACH/Msg1发送；假如终端选择了SSB#1，则终端可以选择与SSB#1关联的RO(RO#0或4)中距离当前时间最近的可用的RO进行PRACH/Msg1发送。在所选择的RO中，终端在所选SSB关联的preamble集合中选择一个preamble进行PRACH的发送。例如，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。终端将选取对应于所选SSB的那个preamble子集里的某个preamble序列用于PRACH/Msg1的发送。
4、R18网络节能
网络能源效率被列为IMT-2020的13项性能要求之一。NR网络的大部分功耗来自基站，NR基站90％的功耗来自有源天线处理单元(Active Antenna Unit，AAU)。由于更高的频段、更宽的带宽、更多的收发机等原因，目前单个NR基站的功耗比LTE高3～4倍。此外，在运营成本方面，基站的电费占整个网络运营成本的近20％。对于一些运营商来说，电费是总利润的一半以上。因此，NR的网络节能对于实现5G的巨大成功变得更加关键。根据实际的负载情况，基站可以实现不同程度的节能措施，例如关闭基站，关闭载波/小区，关闭信道，关闭SSB/波束，关闭天线/面板、小区不连续发送和/或小区不连续接收、信道状态信息(Channel State Information，CSI)自适应等。
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资源确定方法、装置、设备及存储介质进行详细地说明。
本申请实施例提供一种资源确定方法，图2示出了本申请实施例提供的资源确定方法的流程图。如图2所示，本申请实施例提供的资源确定方法可以包括下述的步骤201。
步骤201、终端根据第一信息，确定第二信息。
本申请实施例中，上述第一信息包括以下至少一项：第一配置信息和第一指示信息，该第一指示信息用于指示附加(additional)PRACH资源的激活或去激活相关信息。上述第二信息包括以下至少一项：附加PRACH资源、附加PRACH资源的激活或去激活相关信息。
需要说明的是，本申请实施例所述的附加PRACH资源可以理解为：在传统PRACH资源之外网络侧设备另外配置的PRACH资源，这类型的PRACH资源对于传统终端不可见。
本申请实施例中，上述第一配置信息包括以下至少一项：

可选地，本申请实施例中，上述第一信息可以为或者协议预定义的，或者网络侧设备配置的，或者预配置的。
可选地，本申请实施例中，上述第一信息包括第一配置信息，上述第二信息包括附加PRACH资源。
可选地，本申请实施例中，上述第一信息包括第一配置信息，该第一配置信息包括第二配置信息，上述第二信息包括附加PRACH资源，该第二配置信息用于确定附加PRACH资源的资源位置、映射规则和发送参数中的至少一项。
可选地，本申请实施例中，上述第一信息包括第一配置信息，该第一配置信息包括上述第一有效期、配置有效期、关联关系和分组标识中的至少一项，上述第二信息包括附加PRACH资源的激活或去激活相关信息，即该第一配置信息用于确定附加PRACH资源的激活或去激活相关信息。
可选地，本申请实施例中，上述第一信息包括第一指示信息，上述第二信息包括附加PRACH资源的激活或去激活相关信息。
可选地，本申请实施例中，上述第一配置信息承载在SIB上，该SIB为增加了相关指示域的已有的SIB，或者为新增加的SIB。例如，已有的SIB为SIB1。
可选地，本申请实施例中，在SIB调度信息指示SIB改变的情况下，上述第一配置信息是无效的，直到接收到第一指示信息。可以理解，当第一配置信息和第一指示信息激活了附加PRACH资源后，如果终端收到了承载第一配置信息的网络广播信息，例如SIB信息，的修改信息，终端认为第一配置失效，即对应的附加PRACH资源去激活，直到再次收到关联的第一指示信息。进一步的，修改信息可以是此广播信息中的任意指示域修改，或者只关注第一配置信息是否修改。
可选地，本申请实施例中，上述第一指示信息承载在下行控制信息(Downlink Control Information，DCI)上，该DCI为已有格式的DCI，或者为新增加的其他格式的DCI。例如已有格式的DCI为DCI format 1-0或DCI format 2-7。
可选地，本申请实施例中，上述已有格式的DCI为增加了相关指示域的已有格式的DCI，或者为对已有格式的DCI中已有的指示域重新释义后的DCI。
可选地，本申请实施例中，承载第一指示信息的已有格式的DCI被已有的无线网临时标识(Radio Network Temporary Identifier，RNTI)加扰或新定义的RNTI加扰。
可选地，本申请实施例中，不同格式的DCI用于指示不同状态的终端。其中，DCI为第一DCI格式，第一指示信息用于指示连接态的终端；或者，DCI为第二DCI格式，第一指示信息用于指示空闲态或非激活态的终端。例如，承载第一指示信息的DCI format 1-0用于指示连接态的终端第二信息，承载第一指示信息的DCI format 2-7用于指示空闲态或非激活态的终端第二信息。
可选地，本申请实施例中，上述附加PRACH资源包括以下至少一项：附加RO(additional RACH Occasion)、附加RO组(additional RACH Occasion group)、前导码(Preamble)、前导码组(Preamble group)。
需要说明的是，本申请实施例所述的激活或去激活的有效期(validityduration)也可以称为激活或去激活时间窗。即上述附加PRACH资源是激活的附加PRACH资源的时间窗，或者是去激活的附加PRACH资源的时间窗。
可选地，本申请实施例中，上述激活或去激活相关信息包括以下至少一项：
第一有效期；
附加PRACH资源是激活的或去激活的；
附加PRACH资源的激活的有效期的更新信息；
附加PRACH资源的激活或去激活起始时间；可以理解，终端从起始时间信息可以确定从哪个时刻开始附加PRACH资源是激活或者去激活的。此起始时间也可以被理解为第一有效期的起始时间。
附加PRACH资源的激活或去激活结束时间；可以理解，终端从结束时间可以确定从哪个时刻开始附加PRACH资源不再是激活或者去激活的。此结束时间也可以被理解为第一有效期的结束时间。
可选地，本申请实施例中，上述第一有效期或配置有效期的时间单位包括以下至少一项：N个寻呼周期(paging cycle)、N个非连续接收(Discontinuous Reception，DRX)周期、N个RO映射周期、N个RO映射图样周期、N个随机接入资源配置周期、N个SSB周期、N个帧(frame)、N个毫秒(ms)、N个时隙(slot)、N个符号(symbol)。N为正整数。
例如，上述第一有效期包括{1,2,4,8,16,…256,512}个寻呼周期。
可选地，本申请实施例中，上述第一有效期或配置有效期的默认长度通过以下任一项确定：协议预定义、第一周期与寻呼周期的比值。其中，第一周期包括以下任一项：RO映射周期、RO映射图样周期、随机接入资源配置周期(RACH配置周期)、SSB周期。
可以理解，若上述第一配置信息中没有配置第一有效期，则第一有效期默认为NN个时间单位。例如，NN为协议预定义的2个时间单位，或者NN＝ceil(第一周期/寻呼周期)+K，ceil为取整函数，K为整数，或不存在K。
可选地，本申请实施例中，上述第一有效期或配置有效期关联所有附加PRACH资源。
可选地，本申请实施例中，上述第一有效期或配置有效期关联附加PRACH资源中的1个分组。即第一有效期或配置有效期为每个分组配置的。
可选地，本申请实施例中，上述第一有效期或配置有效期关联附加PRACH资源中的1个资源。即第一有效期或配置有效期为每个附加PRACH资源配置的。
可以理解，当网络侧配置的是配置有效期时，经过配置有效期的有效时间后，即在附加PRACH资源的配置失效后，附加PRACH资源需要重新配置。可选地，配置有效期无论附加PRACH资源是否激活，都在配置后随着时间递减。
可选地，本申请实施例中，上述附加PRACH资源的时频域位置可以由无线资源控制(Radio Resource Control，RRC)配置信息来配置，并且该RRC配置信息还可以配置附加PRACH资源的激活的有效期。其中，RRC配置信息可以承载在SIB1或SIB17等已有的SIB或一个新的SIB中。
示例性地，附加PRACH资源的激活的有效期的单位为1个寻呼周期，RRC配置信息中会从激活的有效期的选择范围中配置一个有效期。例如，激活的有限期的范围被预定义为1个集合，该1个集合中的值为{1,2,4,8…128,256,512}等。RRC配置信息利用4个比特配置一个具体的有效期的值。当RRC配置信息没有此指示域时，默认激活有效期为2个寻呼周期。
需要说明的是，上述RRC配置信息中的激活的有效期可以是关联所有的附加PRACH资源，也可以是针对每个附加PRACH资源的一个分组进行配置，或者针对每个附加PRACH资源中的一个资源进行配置。
可选地，本申请实施例中，针对附加PRACH资源的激活的有效期的更新信息：一种情况是附加PRACH资源的有效期激活后不允许网络侧设备通过物理层信令关掉有效期，此时，物理层信令只起到一个激活有效期配置以及重置有效期的功能。另一个情况是物理层信令可以激活附加PRACH资源的激活的有效期，也可以暂停有效期。
需要说明的是，本申请实施例中，附加PRACH资源的有效期可以是激活的有效期，也可以是去激活的有效期。为防止赘述，以下说明均以有效期为附加PRACH资源的激活有效期进行说明。可以理解，终端认为有效期之外附加PRACH资源是去激活的。如果有效期为附加PRACH资源的去激活有效期，则终端认为有效期之外的附加PRACH资源是激活的。
本申请实施例中，上述附加PRACH资源的激活的有效期的更新信息用于指示附加PRACH资源的激活的有效期是否重置。
可选地，本申请实施例中，在上述第一指示信息中的第一比特为第一值的情况下，上述激活或去激活相关信息指示第一比特关联的附加PRACH资源的激活的有效期重置。
需要说明的是，激活或去激活相关信息指示附加PRACH资源的激活的有效期重置可以理解为：激活或去激活相关信息指示附加PRACH资源的激活的有效期为第一有效期，或者可以理解为指示第一配置信息中的有效期生效。可以理解，终端根据此激活或去激活相关信息，可以确定附加PRACH资源的激活的有效期的时间长度进行了更新，即更新为了第一有效期。同时，终端还可以根据此有效期的重置信息确定出关联附加PRACH资源的激活或去激活起始时间以及结束时间。相对应的，哪些附加PRACH资源是激活的还是去激活的也可以被终端确定。
示例性地，上述第一值为1。可以理解，上述第一值也可以为0。
可选地，本申请实施例中，在上述第一指示信息中的第一比特为第一值的情况下，上述激活或去激活相关信息指示第一比特关联的附加PRACH资源的激活的有效期递减。
需要说明的是，激活或去激活相关信息指示附加PRACH资源的激活的有效期递减(即按照时间单位正常递减)可以理解为：激活或去激活相关信息指示对附加PRACH资源的激活或去激活的假设不变(例如对激活的有效期的时长的假设不变)。可以理解，终端根据此激活或去激活相关信息，可以确定附加PRACH资源的激活的有效期的时间长度或时间范围没有发生改变。同时，终端还可以确定关联附加PRACH资源的激活或去激活起始时间以及结束时间没有发生变化。相对应的，终端也可以确定，随着时间单位的递减，哪些附加PRACH资源是激活的还是去激活的。
可选地，本申请实施例中，在上述第一指示信息中的第一比特为第二值的情况下，上述激活或去激活相关信息指示第一比特关联的附加PRACH资源的激活的有效期暂停。
可以理解，附加PRACH资源关联的比特在指示第二值的时候，终端认为附加PRACH资源暂时去激活，此时，有效期暂停，不进行递减，直到第一指示信息再次指示第一值，或者有效期重新配置。可以理解，终端根据此激活或去激活相关信息，可以确定附加PRACH资源的激活的有效期的时间长度或时间范围发生了更新，因为激活或去激活的结束时间发生了改变。同时，终端还可以确定哪些附加PRACH资源是激活或去激活的。还有一种可能是，当附加PRACH资源关联的比特在指示第二值的时候，终端认为附加PRACH资源暂时去激活，且此时有效期正常递减，即有效期的时长无论关联的附加PRACH资源是激活还是去激活，都随着时间递减。可以理解，终端根据此激活或去激活相关信息，可以确定附加PRACH资源的激活的有效期的时间长度或时间范围没有发生更新。但是此时，有效期范围内哪些附加PRACH资源是激活或去激活的发生了改变，终端可以根据此信息进行确定。
可选地，本申请实施例中，在上述第一指示信息中的第二比特为第一值、且第一指示信息中的第一比特为第一值的情况下，上述激活或去激活相关信息指示第二比特和第一比特关联的附加PRACH资源的激活的有效期递减。可以理解，终端根据此激活或去激活相关信息，可以确定附加PRACH资源的激活的有效期的时间长度或时间范围没有发生改变。同时，终端还可以确定关联附加PRACH资源的激活或去激活起始时间以及结束时间没有发生变化。相对应的，终端也可以确定，随着时间单位的递减，哪些附加PRACH资源是激活的还是去激活的。
可以理解，附加PRACH资源关联2个比特位，1个比特位指示有效期是否重置，另1个比特位指示有效期是否递减。相比1个比特只指示有效期是否重置的指示方式，可以避免终端在没有收到指示信息时，无法判断附加PRACH资源的激活与否。
可选地，本申请实施例中，在上述第一指示信息中的第二比特为第一值、且第一指示信息中的第一比特为第二值的情况下，上述激活或去激活相关信息指示第二比特和第一比特关联的附加PRACH资源的激活的有效期暂停。可以理解，终端根据此激活或去激活相关信息，可以确定附加PRACH资源的激活的有效期的时间长度或时间范围发生了更新，因为激活或去激活的结束时间发生了改变。相对应的，终端也需要重新确定附加PRACH资源的激活与否。
需要说明的是，有效期是否递减还可以指是否暂停有效期，即有效期不递减等同于暂停有效期，有效期递减等同于不暂停有效期。可以理解，有效期递减即认为关联的附加PRACH资源是激活的，有效期暂停认为此时关联的附加PRACH资源是去激活的。
需要说明的是，当有两个关联比特时，上述第一比特用于判断比特位关联的附加PRACH资源的激活的有效期是否递减或暂停；上述第二比特用于判断比特位关联的附加PRACH资源的激活的有效期是否重置。
或者，上述第一比特用于判断比特位关联的附加PRACH资源时是否激活；上述第二比特用于判断比特位关联的附加PRACH资源的激活的有效期是否重置。
或者，上述第一比特用于判断比特位关联的附加PRACH资源时是否激活；上述第二比特用于判断比特位关联的附加PRACH资源的激活的有效期是否递减或暂停。
可选地，本申请实施例中，上述第一比特可以是第一个比特位，上述第二比特可以是第一比特的下一个比特位。可以理解，第一比特也可以是附加PRACH资源关联的第二个比特位，此时上述第二比特是第一比特的上一个比特位。
示例性地，上述第二值为0。可以理解，上述第二值也可以为0。
可选地，本申请实施例中，在上述第一指示信息中的第一比特为第二值或者没有接收到第一指示信息的情况下，上述激活或去激活相关信息指示第一比特关联的附加PRACH资源的激活的有效期递减。
需要说明的是，每个比特位关联的附加PRACH资源是网络侧设备配置的，即每个指示比特位关联的附加PRACH资源是确定的，与接收到或没有接收到第一指示信息无关，因此即使没有接收到第一指示信息，上述激活或去激活相关信息可以指示第一比特关联的附加PRACH资源的激活的有效期递减，即终端认为第一比特关联的附加PRACH资源的激活的有效期递减。
可选地，本申请实施例中，在上述第一指示信息中的第一比特为第二值的情况下，上述激活或去激活相关信息指示第一比特关联的附加PRACH资源去激活，直到接收到第一比特为第一值的指示。可以理解，此时只要接收到第一比特为第二值的指示，就认为关联的PRACH资源去激活。
可选地，本申请实施例中，在上述第一指示信息中的第一比特为第二值的情况下，上述激活或去激活相关信息指示第一比特关联的附加PRACH资源的激活有效期不递减，直到接收到第一比特为第一值的指示。可以理解，当第一比特为第二值时，有效期暂停，直到第一比特为第一值。
可选地，本申请实施例中，在没有接收到第一指示信息的情况下，是否去激活附加PRACH资源或是否将激活的有效期递减，根据上次接收的指示信息确定。可以理解，终端在因为各种原因没有接收到第一指示信息时，根据之前接收到的指示信息确定附加PRACH资源的激活或去激活相关信息。例如，当上次接收到的指示信息指示某些附加PRACH资源是激活，此时仍然认为是激活的；又或者，上次接收到的指示信息指示有效期在正常递减，此时也认为有效期在正常递减。
可选地，本申请实施例中，在上述第一指示信息中的第一比特为第二值，且没有接收过第一比特为第一值的指示信息的情况下，上述激活或去激活相关信息指示第一时间窗内的附加PRACH资源是激活的，该第一时间窗为有效期内当前的周期或者有效期内当前的周期之后的至少一个周期。
可以理解，终端可能没有接收到有效期设置或更新的相关信令，当只能确定当前处于有效期内时，如何确定后续的附加PRACH资源是否激活需要确定。由于可以确定当前处于有效期内，那么终端根据上述这个信息，认为第一时间窗内的附加PRACH资源是激活的。
需要说明的是，网络侧设备是周期性发送第一指示信息，终端在接收到过第一比特为第二值的第一指示信息，且没有接收到过第一比特为第一值的第一指示信息的情况下，激活或去激活相关信息指示第一时间窗内的附加PRACH资源是激活的。可以理解，第一比特为第二值时，表示激活有效期在正常递减，所以即使没有接收到指示有效期生效的第一指示信息，终端至少可以确定当前有效期的周期内附加PRACH资源是激活的。
可选地，本申请实施例中，在接收过第一比特为第一值的第一指示信息的情况下，上述激活或去激活相关信息指示第一时间窗内的附加PRACH资源是激活的。
可选地，本申请实施例中，在第二时间窗内接收过第一比特为第一值的第一指示信息的情况下，当接收到第一比特为第二值的第一指示信息时，终端认为第一时间窗内的附加PRACH资源是激活的。可以理解，终端只有在第二时间窗内接收过第一比特为第一值的第一指示信息的情况下，上述情况才认为成立，否则，不能认为第一时间窗内的附加PRACH资源是激活的。
可选地，本申请实施例中，上述第二时间窗的结束位置为接收第一比特为第二值的第一指示信息的时刻，或该时刻之前。其中，第二时间窗可以是至少一个时间单位，该时间单位可以包括以下任一项：毫秒、时隙、符号、子帧、帧、DRX周期、寻呼周期、随机接入资源配置周期、SSB-RO映射周期、SSB-RO映射图样周期。
可选地，本申请实施例中，在没有接收到用于指示激活附加PRACH资源的第一指示信息的情况下，上述附加RACH资源是不可用的。可以理解，在网络侧配置了附加PRACH资源的有效期信息后，需要第一指示信息进行指示，才认为此配置开始生效。
可选地，本申请实施例中，上述附加PRACH资源的激活或去激活起始时间为以下任一项：
上述第一有效期内附加PRACH资源的第一个配置周期、或第一个SSB-RO映射图样周期、或第一个SSB-RO映射周期；
上述第一有效期内第一个附加PRACH资源；
下一个寻呼周期或下一个DRX周期；
当前寻呼周期或当前DRX周期；
上述第一指示信息的接收时刻；
上述第一指示信息接收时刻后的第一个附加PRACH资源位置；
上述第一指示信息接收后至少一个时间单位后的时刻；
上述第一指示信息接收后至少一个时间单位后的第一个附加PRACH资源位置。
可选的，本申请实施例中，上述至少一个时间单位包括第一指示的处理时间和混合自动重传请求确认(Hybrid Automatic Repeat reQuest-Acknowledgement，HARQ-ACK)反馈时间的至少一项。
可选地，本申请实施例中，上述附加PRACH资源与第一指示信息的关联关系，包括：每个附加PRACH资源的标识分别与第一指示信息中的一个比特位关联。
可以理解，上述第一指示信息中至少一个比特位中的每个比特位分别关联一个附加PRACH资源。
可选地，本申请实施例中，上述每个附加PRACH资源的标识分别与第一指示信息中的一个比特位关联，包括：标识为i的附加PRACH资源与第一指示信息中的第i+1个比特位关联，i为正整数。
可以理解，每个附加PRACH资源被配置1个标识，附加PRACH资源的标识i与第一指示信息中的第i+1个比特位关联。即网络侧设备在配置附加PRACH资源时，给每个附加PRACH资源赋予一个id，这样第一指示信息如果按组对附加PRACH资源进行激活或去激活时，只需要采用1个比特图(bitmap)就可以指示哪部分附加PRACH资源的激活或去激活相关信息。可以理解，不同的附加PRACH资源可以被配置相同的标识，即对附加PRACH资源进行分组。特别的，如果不对附加PRACH资源进行分组，那么第一指示信息只需要1个比特位就可以实现对所有附加PRACH资源的激活或去激活相关信息的指示。
可选地，本申请实施例中，上述第二配置信息包括以下至少一项：
SSB索引；
附加PRACH的配置索引；
第一PRACH的配置信息对应的第三信息，第三信息包括以下至少一项：缩放因子、偏移值；
附加PRACH资源与第一PRACH资源的关系；
PRACH资源参数；
功率参数；
竞争及测量相关的参数。
需要说明的是，上述第一PRACH可以为传统(legacy)PRACH，或者是网络侧设备已配置或已存在的PRACH，或者是对应已有标准版本的PRACH。
可选地，本申请实施例中，上述SSB索引(index)为与附加PRACH资源具有准共址(Quasi Co-Location，QCL)关系的SSB索引。
可选地，本申请实施例中，上述附加PRACH的配置索引用于从第一表格中确定附加PRACH资源，该第一表格中包括至少一个PRACH配置索引和对应的Preamble格式，PRACH资源配置周期，以及PRACH资源所在的无线帧位置，子帧位置，起始符号等。
可以理解，终端根据网络侧设备配置的附加PRACH的配置索引(additional 
PRACH configuration index)从第一表格中确定该附加PRACH的配置索引对应的PRACH资源，作为上述附加PRACH资源。
示例性地，上述第一表格如表1所示，第一PRACH通过PRACH配置索引指示行5，附加PRACH通过附加PRACH的配置索引指示行17，从而第一PRACH的时域资源为偶数SFN的子帧(subframe)4，附加PRACH配置的时域资源为每一个SFN中的subframe 4，9。PRACH时隙内的时域PRACH次数。
表1
可选地，本申请实施例中，上述第一PRACH的配置信息包括以下至少一项：系统帧号(System Frame Number，SFN)的子帧、SFN的开始符号、SFN的PRACH时隙数目、SFN的PRACH时机数目、SFN的PRACH长度。
示例性地，上述附加PRACH资源根据第一PRACH的配置信息对应的第三信息确定。在上述表1中，配置nf，x，y，子帧号，开始符号的缩放因子(或偏移值offset)。nf是RO所在的无线帧位置，x是RO的配置周期，y是用于确定nf的中间值。
例如，第一PRACH通过PRACH配置索引指示行5，从而第一PRACH的时域资源为偶数SFN(SFN 0，2，4……)的subframe 4，网络侧设备配置参数SFN-offset为m，则附加PRACH资源为SFN(m,2+m,4+m……)的subframe 4，如果网络侧设备配置了参数subframe-offset或slot-offset为n，则附加PRACH资源为SFN(SFN 0，2，4……)的subframe(4+n)，如果网络侧设备同时配置了SFN-offset为m，subframe-offset或slot-offset为n，则附加PRACH资源为SFN(n,2+n,4+n……)的subframe(4+n)。
例如配置xn为x的缩放因子，则附加PRACH的x’＝x*xn。可以理解，附加PRACH资源的配置周期根据第一PRACH资源的配置周期进行缩放。
可选地，本申请实施例中，上述附加PRACH资源与第一PRACH资源(legacy PRACH资源)的关系，包括以下任一项：
附加PRACH资源与第一PRACH资源不重叠；
附加PRACH资源与第一PRACH资源有重叠；
附加PRACH资源与第一PRACH资源的资源位置具有间隔；
被网络掩码(mask)的第一PRACH资源，作为附加PRACH资源。
可选地，本申请实施例中，上述附加PRACH资源与第一PRACH资源有重叠。其中，重叠的资源用于第一PRACH资源进行SSB与RO的映射，不作为附加PRACH资源；或者，重叠的资源可进行SSB与RO的映射，且在映射后附加PRACH资源的RO是无效的；或者，附加PRACH资源与第一PRACH资源的RO不可部分重叠，可完全重叠；或者，在一个SSB映射多个RO的情况下，附加PRACH资源与第一PRACH资源没有重叠的资源被网络优先掩码。
可选地，本申请实施例中，上述间隔与子载波间隔(Sub-Carrier Space，SCS)和PRACH的序列长度中的至少一项有关。
可选地，本申请实施例中，被网络掩码的第一PRACH资源，作为附加PRACH资源。其中，被网络掩码的第一PRACH资源的RO不能被取消掩码；或者，在被网络掩码的第一PRACH资源的RO被取消掩码的情况下，RO不再作为附加PRACH资源。
可选地，本申请实施例中，在RO不再作为附加PRACH资源的情况下，附加PRACH资源与SSB重新映射，或者，附加PRACH资源与SSB的映射关系不变且RO是不可用的。
可以理解，对于附加PRACH资源和第一PRACH资源的关系，可以包括以下情况1至情况4至少一种：
情况1、网络侧设备配置附加PRACH资源，避免配置和第一PRACH(或至少是没有掩码mask的PRACH资源)有重叠，或者说终端不期待网络侧设备配置第一PRACH和附加PRACH重叠。重叠的情况包括以下至少一项：时域部分或完全重叠、频域部分或完全重叠。
情况2、网络侧设备可以配置附加PRACH资源和第一PRACH(或至少是没有mask的PRACH资源)有重叠，重叠的情况包括以下至少一项：时域部分或完全重叠、频域部分或完全重叠。对于重叠的资源，可以有以下的方式(1)至方式(4)中的至少一项处理：
方式(1)重叠的资源只能用于第一PRACH用于SSB-RO的映射，不能作为附加PRACH，或者说当发生重叠，该附加RO是无效的，在附加RO的SSB-RO映射过程中不映射该附加RO，或者说重叠时认为重叠的RO不属于附加PRACH资源。
换句话说，附加RO的有效性通过legacy RO或者没有mask去掉的legacy RO来判断。
方式(2)重叠的资源可以进行SSB-RO的映射，但是映射后，认为该附加RO是无效的。
方式(3)RO不可以部分重叠，但是可以完全重叠，或者说可以共享RO，可以理解为终端不期待RO配置为部分重叠的情况，或者当部分重叠，按照上述方式(1)或方式(2)处理，当完全重叠，可以通过不同的preamble区分legacy RO和附加RO。
方式(4)当一个SSB对应多个RO，网络侧设备通过配置PRACH mask使得映射的部分的RO用于传输PRACH，网络侧设备优先mask没有重叠的资源。
情况3、网络侧设备配置附加RO的时域和频域位置中的至少一项，以及第一PRACH(或至少是没有mask的PRACH资源)满足一定的间隔。可选地，该间隔与SCS、PRACH的序列长度中的至少一项有关。
例如，配置legacy RO的时域在子帧4，则附加RO的时域在子帧4间隔至少2个子帧以上的子帧。
可选地，当配置的附加RO和第一PRACH(或至少是没有mask的PRACH资源)不满足上述间隔时，采用上述方式(1)或方式(2)的处理方法。
情况4、被网络mask的legacy RO，可以被网络侧配置或指示为附加PRACH资源。
可选地，如果被配置为附加PRACH资源，则这些RO不能被取消mask。
可选地，如果被mask的legacy RO被取消mask，则这些RO不再是附加PRACH资源。
可选地，重新进行SSB与附加PRACH资源的映射。
可选地，映射关系不变，但认为这些附加PRACH资源不可用。
可选地，本申请实施例中，上述PRACH资源参数(为了区分第一PRACH和附加PRACH资源)包括以下至少一项：PRACH配置索引、RO频域的起始位置、RO在频域复用的数目、一个RO对应的SSB的数目、用于附加PRACH的SSB的子集、用于附加PRACH的前导码的子集、PRACH掩码指示。
可选地，本申请实施例中，上述功率参数包括以下至少一项：功率增长步长(power ramping)、初始前导码功率(preambleReceivedTargetPower)。由于附加PRACH的配置不同可能得到不同的目标功率，所以需要配置不同的功率参数使得终端的发送功率保持一致。
可选地，本申请实施例中，上述竞争及测量相关的参数包括以下至少一项：随机接入响应(Random Access Response，RAR)窗口的大小、测量SSB的信号质量(例如RSRP)阈值、解决竞争计时器。
可选地，本申请实施例中，在上述附加PRACH资源的激活的有效期与附加PRACH资源的配置周期重叠的情况下，包括以下任一项：
重叠时间内的附加PRACH资源是激活的；
重叠时间所在的附加PRACH资源的配置周期内的附加PRACH资源是激活的；
当附加PRACH资源所在的配置周期都位于附加PRACH资源的激活的有效期内时，附加PRACH资源是激活的。
本申请实施例中，由于附加PRACH资源的激活指示(即上述第一指示信息)承载在寻呼相关的DCI(例如DCI format 1-0或DCI format 2-7)中，而这些DCI的发送频率与寻呼周期有关，因此附加PRACH资源的激活的有效期也以寻呼周期为单位。但是附加PRACH资源的配置与随机接入资源配置周期(RACH配置周期)有关，因此当寻呼周期与随机接入资源配置周期不一样时，激活的有效期很难与随机接入资源配置周期完全对齐。因此就会出现当激活的有效期递减到最后一个寻呼周期时，激活的有效期的范围可能只包含到一个配置周期内的部分附加PRACH资源。此时，这个配置周期内的附加PRACH资源是否激活需要确定。如上所述，可以只认为激活有效期范围内的附加PRACH资源是激活的，即使有效期之外的部分附加PRACH资源与有效期范围内的部分附加PRACH资源属于同一个配置周期。另一种可能是认为只要有重叠部分，就认为配置周期内的是所有附加PRACH资源都是激活的。还有一种可能是认为只有当配置周期内所有附加PRACH资源都位于激活有效期范围内，这些附加PRACH才被认为是激活的。
本申请实施例中，对于上述第一有效期或附加PRACH资源的配置有效期：可以控制激活或去激活附加PRACH资源的时间长度，且在终端没有接收到激活或去激活的相关指示信息时，仍可以确定附加PRACH资源是否是激活的。
对于上述附加PRACH资源与第一指示信息的关联关系：有利于网络侧设备用物理层或媒体访问控制(Media Access Control，MAC)层信令更加动态灵活地控制附加PRACH资源的激活或去激活。
对于上述附加PRACH资源的分组标识：有利于网络侧设备更精细地管理附加PRACH的激活与否，例如根据不同方向的拥塞程度激活不同数量或不同波束方向的PRACH资源。
对于上述第二配置信息：用于帮助终端确定附加PRACH资源的资源位置、映射规则和发送参数中的至少一项等。
需要说明的是，为了网络节能，引入附加PRACH资源。当网络较空闲时，去激活附加PRACH资源，此时网络只需要在少数PRACH资源上检测终端的随机接入行为。而当网络较繁忙时，激活附加PRACH资源，满足终端的随机接入需求。
本申请实施例提供一种资源确定方法，终端根据第一信息确定第二信息，该第一信息包括第一配置信息和第一指示信息中的至少一项，第二信息包括附加PRACH资源和附加PRACH资源的激活或去激活相关信息中的至少一项。本方案中，由于终端可以根据附加PRACH资源的配置信息或激活或去激活相关信息的指示信息，确定附加PRACH资源或激活或去激活相关信息，以实现附加PRACH资源的配置与指示，从而通过附加PRACH资源达到网络节能的效果。
