Description

功率的确定方法及装置 技术领域
本发明涉及通信领域，尤其涉及一种功率的确定方法及装置。
背景技术
在随机接入(RA，Random Access)过程中，用户设备(UE，User Equipment)向网络侧发送消息1(MSG1)以提出随机接入请求，网络侧以广播的方式发出消息2(MSG2)，在MSG2中，网络侧指示没有成功接收随机接入响应(RAR，Random Access Response)的用户设备所采用的退避时间。
另外，随机接入过程可以分为基于竞争的随机接入(CBRA，Contention Based Random Access)和非竞争的随机接入过程(CFRA，Contention-Free Random Access)。在CBRA中，UE共享随机接入前导码(Random Access Preamble)，因此，多个UE之间可能发生随机接入冲突；而在CFRA中，网络设备可为UE指定随机接入前导码，从而避免与其他UE的随机接入过程冲突。
应该注意，上面对技术背景的介绍只是为了方便对本发明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发明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
在新无线(NR，New Radio)系统的研究中，在介质访问控制(MAC，Media Access Control)层，随机接入(RA，Random Access)过程可以包括以下步骤：步骤1、随机过程发起；步骤2、基于配置的同步信号块(SSB，Synchronizing Signal Block)和/或信道状态信息参考信号(CSI-RS，Channel State Information Reference Signal)资源的无线信道质量以及是否有对应的专用资源/前导码等因素，选择一个SSB或CSI-RS资源，或随意选择一个SSB；步骤3、选择和/或使用与选择的SSB或CSI-RS资源相应的RA资源发送与选择的SSB或CSI-RS资源相应的随机接入前导码；步骤4、对于成功接收接收随机接入响应(RAR，Random Access Response)的UE，在CBRA的情况下，当冲突解决时RA完成，当冲突未解决时返回步骤2重新选择资源并重新发 送随机接入前导码，在CFRA的情况下，RA完成，对于未成功接收RAR的UE，返回步骤2重新选择资源并重新发送随机接入前导码。
在每次执行上面的步骤3时，MAC层都会向低层指示此次发送随机接入前导码所对应的目标接收功率，以便物理层计算出相应的随机接入前导码的发送功率。
在重新发送随机接入前导码的情况下，由于功率提升机制，MAC层指示给低层的目标接收功率可以缓慢上升，这样，上行重传可以以等于或稍高于上次传输的功率进行发送，既有利于网络侧的成功接收，还不会对其他UE造成太大干扰。使用与功率提升相关的计数器来确定当前传输相较于上次传输是否增加目标接收功率，即PREAMBLE_POWER_RAMPING_COUNTER。
根据当前的机制，从资源选择角度来说，只有在选择的SSB不改变的情况下，与功率提升相关的计数器才会加1，这样指示给低层的目标接收功率才会增加。在其他情况下，该计数器保持不变。
此外，根据当前的机制，当决定与功率提升相关的计数器是否加1时，MAC层还需要考虑是否从物理层收到计数器挂起指示。当收到该指示时，与功率提升相关的计数器保持不变。其中，如果在进行物理随机接入信道(PRACH，Physical Random Access Channel)重传前，UE改变空域发送滤波器，那么物理层将通知MAC层挂起功率提升相关的计数器，及发送计数器挂起指示。
因此，如果按照当前的机制决定是否进行功率提升，则存在以下的问题：当前的机制只考虑了选择SSB的情况，因此无论是当前的随机接入资源选择过程还是前一次的随机接入资源选择过程，只要选择了CSI-RS资源，那么将不会触发功率提升，因此当前随机接入前导码发送时的功率都与之前相同。在极端情况下，每次重传随机接入前导码时都选择了CSI-RS资源，则随机接入前导码重传过程里无法应用功率提升机制，这可能导致无用的重传，增加了UE的功率消耗，并导致网络侧无法正确接收随机接入前导码，降低了随机接入的成功率。
本发明实施例提供一种功率的确定方法及装置，根据选择的SSB和CSI-RS资源中任一个的变化情况，确定是否提升目标接收功率，从而考虑了选择CSI-RS资源的情况，能够在必要的情况下进行功率提升并避免无用的重传，从而提高了随机接入的成功率并减少了UE的功率消耗。

实施例1
本发明实施例提供一种功率的确定方法，该方法应用于用户设备侧。
图2是本发明实施例1的功率的确定方法的一示意图。如图2所示，该方法包括：
步骤201：根据选择的同步信号块(SSB)和信道状态信息参考信号(CSI-RS)资源中任一个的变化情况，确定是否提升目标接收功率，
其中，选择的该SSB或CSI-RS资源用于确定随机接入(RA)资源，该目标接收功率用于确定随机接入前导码的发送功率。
这样，根据选择的SSB和CSI-RS资源中任一个的变化情况，确定是否提升目标接收功率，从而考虑了选择CSI-RS资源的情况，能够在必要的情况下进行功率提升并避免无用的重传，从而提高了随机接入的成功率并减少了UE的功率消耗。
在本实施例中，选择的SSB或CSI-RS资源可以是，例如，基于配置的SSB和/或CSI-RS资源的无线信道质量以及是否有对应的专用资源/前导码等因素，选择一个SSB或CSI-RS资源，或随意选择一个SSB。
在本实施例中，选择SSB或CSI-RS资源的目的是确定与选择的该SSB或CSI- RS资源对应的RA资源以及随机接入前导码的索引，用户设备可以使用该RA资源发送该索引指示的随机接入前导码。
在本实施例中，SSB或CSI-RS资源与RA资源以及随机接入前导码的索引可以具有映射关系，例如，该映射关系可以是网络设备侧预先配置给用户设备的。
在本实施例中，该目标接收功率用于确定随机接入前导码的发送功率，即用户设备发送随机接入前导码的功率。
例如，用户设备使用网络设备侧配置的最大功率P CMAX,f,c(i)与(目标接收功率+路损)这两者之间较小的值来发送随机接入前导码。其中，目标接收功率可以由MAC层告知，该路损可以由系统信息提供的参考信号功率减去高层滤波后的参考信号接收功率(RSRP，Reference Signal Receiving Power)值得到。
在本实施例中，选择的SSB和CSI-RS资源中任一个的变化情况可以包括：选择的资源的种类的变化，和/或，选择的资源所配置的具体物理资源的变化。
在本实施例中，在确定选择的SSB和CSI-RS资源中任一个的变化情况时，可以将当前选择的SSB或CSI-RS资源与前一次的选择结果进行比较，也可以将当其次选择的SSB或CSI-RS与之前所有的选择结果进行比较。
例如，该方法还可以包括：
步骤202：根据当前选择的SSB或CSI-RS资源与前一次选择的SSB或CSI-RS资源的比较结果，或者，根据当前选择的SSB或CSI-RS资源与之前选择的SSB和/或CSI-RS资源的比较结果，确定选择的SSB和CSI-RS资源中任一个的变化情况。
例如，根据当前选择的SSB或CSI-RS资源的种类以及配置的物理资源与前一次选择的资源的种类以及配置的物理资源的比较结果，或者，根据当前选择的SSB或CSI-RS资源的种类以及配置的物理资源与之前选择的所有资源的种类以及配置的物理资源的比较结果，确定选择的SSB和CSI-RS资源中任一个的变化情况。
在本实施例中，选择的SSB或CSI-RS资源的种类指的是选择的是SSB还是CSI-RS资源，即，SSB与CSI-RS资源属于不同种类的资源。
在本实施例中，配置的物理资源指的是SSB或CSI-RS资源具体所配置的物理资源，例如，选择的该SSB所配置的物理资源是哪些频率，和/或，哪些符号或时隙，选择的该CSI-RS资源所配置的物理资源是哪些频率，和/或，哪些符号或时隙。
在本实施例中，判断SSB或CSI-RS资源所配置的物理资源是否相同，可以根据 SSB的索引或CSI-RS资源的ID是否相同来进行判断，也就是说，不同索引的SSB配置有不同的物理资源，不同ID的CSI-RS资源也配置有不同的物理资源。
在本实例中，将不同索引的SSB简称为不同的SSB，将不同ID的CSI-RS资源简称为不同的CSI-RS资源。也就是说，不同的SSB配置有不同的物理资源，不同的CSI-RS资源也配置有不同的物理资源。
以下对步骤202中如何根据比较结果来确定选择的SSB和CSI-RS资源中任一个的变化情况进行示例性的说明。
首先，针对当前选择的是SSB的情况进行说明。
例如，当前选择的是SSB，前一次选择的是SSB，且两个SSB相同时，确定选择的SSB没有改变；
例如，当前选择的是SSB，且当前选择的SSB与之前选择过的所有SSB中的一个SSB相同时，确定选择的SSB没有改变；
例如，当前选择的是SSB，前一次选择的是CSI-RS资源，且当前选择的SSB和与前一次选择的CSI-RS资源准共置的SSB相同时，确定选择的SSB没有改变；
例如，当前选择的是SSB，且当前选择的SSB和与之前选择过的所有CSI-RS中的一个CSI-RS资源准共置的SSB相同时，确定选择的SSB没有改变。
例如，针对当前选择的是SSB，对于上述示例以外的其他情况，可以确定选择的SSB发生了改变。
其次，针对当前选择的是CSI-RS资源的情况进行说明。
例如，当前选择的是CSI-RS资源，前一次选择的是CSI-RS资源，且这两个CSI-RS资源相同时，确定选择的CSI-RS资源没有改变；
例如，当前选择的是CSI-RS资源，且当前选择的CSI-RS资源与之前选择过的所有CSI-RS资源中的一个CSI-RS资源相同时，确定选择的CSI-RS没有改变；
例如，当前选择的是CSI-RS资源，前一次选择的是SSB资源，且与当前选择的CSI-RS资源准共置的SSB和前一次选择的SSB相同时，确定选择的CSI-RS资源没有改变；
例如，针对当前选择的是CSI-RS资源，对于上述示例以外的其他情况，可以确定选择的CSI-RS资源发生了改变。
在本实施例中，对于某些情况，当考虑了CSI-RS资源与SSB的准共置关系或者 没有考虑该准共置关系时，确定选择的CSI-RS资源是否发生改变的结果可能不同。
例如，当前选择的是CSI-RS资源，前一次选择的也是CSI-RS资源，这两个CSI-RS资源不同，但是，与当前选择的CSI-RS资源准共置的SSB与前一次选择的CSI-RS资源准共置的SSB相同，当考虑了CSI-RS资源与SSB的准共置关系时，可以确定为选择的CSI-RS资源没有改变，或者，也可以确定为选择的CSI-RS资源发生了改变，当没有考虑CSI-RS资源与SSB的准共置关系时，可以确定为选择的CSI-RS资源发生了改变。
又例如，当前选择的是CSI-RS资源，当前选择的CSI-RS资源与之前选择过的所有CSI-RS资源都不相同，但是，当前选择的CSI-RS资源准共置的SSB和与之前选择过的所有CSI-RS资源中的至少一个CSI-RS资源准共置的SSB相同，当考虑了CSI-RS资源与SSB的准共置关系时，可以确定为选择的CSI-RS资源没有改变，或者，也可以确定为选择的CSI-RS资源发生了改变，当没有考虑CSI-RS资源与SSB的准共置关系时，可以确定为选择的CSI-RS资源发生了改变。
在本实施例中，对于以上例举的两种情况，在确定选择的CSI-RS资源是否发生改变时，是否考虑CSI-RS资源与SSB的准共置关系，以及在考虑了该准共置关系时的确定规则，可以是预先定义的，或者，由网络设备侧预先配置的。
以下，对应于上述步骤202和步骤201，对根据选择的SSB和CSI-RS资源中任一个的变化情况确定是否提升目标接收功率的具体方式进行示例性的说明。
例如，在选择的SSB和CSI-RS资源中的任一个没有发生改变的情况下，确定提升所述目标接收功率。
这样，在选择的SSB或CSI-RS资源没有改变的情况下提升重传随机接入前导码的发送功率，能够合理的利用功率提升机制，提高随机接入的成功率。
下面，通过示例的方案给出确定提升目标接收功率和不提升目标接收功率各自的条件。
例如，方案1)在选择的SSB发生改变的情况下，确定不提升目标接收功率；在选择的SSB发生改变以外的其他情况下，确定提升目标接收功率。
这样，对于当前选择了CSI-RS资源且没有改变的情况可以进行合理的处理，即进行功率提升。
例如，方案2)在选择的SSB和CSI-RS资源中的任一个没有发生改变的情况下， 确定提升目标接收功率；在选择的SSB和CSI-RS资源中的任一个没有发生改变的情况以外的其他情况下，确定不提升目标接收功率。
这样，对于当前与之前选择了同一种资源的情况，例如都选择了SSB或都选择了CSI-RS资源，可以进行合理的处理。
例如，方案3)在选择的SSB和CSI-RS资源中的任一个发生改变的情况下，确定不提升目标接收功率；在选择的SSB和CSI-RS资源中的任一个发生改变的情况以外的其他情况下，确定提升目标接收功率。
这样，对于当前与之前选择了同一种资源的情况，例如都选择了SSB或都选择了CSI-RS资源，可以进行合理的处理。
例如，方案4)在选择的SSB发生改变或与选择的CSI-RS资源准共置的SSB发生改变的情况下，确定不提升目标接收功率；在选择的SSB发生改变和与选择的CSI-RS资源准共置的SSB发生改变的情况以外的其他情况下，确定提升目标接收功率。
这样，考虑了CSI-RS资源与SSB的准共置关系，从而不管当前选择了何种资源，都可以进行合理的处理。在本实施例中，对于方案2)，例如，在选择的SSB的种类发生改变或者选择的CSI-RS资源的种类发生改变的情况下，或者，在选择的SSB或者CSI-RS资源的种类没有发生改变但是选择的物理资源发生改变的情况下，确定不提升目标接收功率。
在本实施例中，选择的SSB或CSI-RS资源的种类指的是选择的是SSB还是CSI-RS资源，即，SSB与CSI-RS资源属于不同种类的资源。例如，当前选择的是SSB，前一次选择的是CSI-RS资源，则选择的SSB的种类发生了改变。
在本实施例中，配置的物理资源指的是SSB或CSI-RS资源具体所配置的物理资源，例如，选择的该SSB所配置的物理资源是哪些频率，和/或，哪些符号或时隙，选择的该CSI-RS资源所配置的物理资源是哪些频率，和/或，哪些符号或时隙。例如，当前选择的是SSB，前一次选择的也是SSB，但是两次选择的SSB所配置的物理资源是不同的，则选择的SSB种类没有改变但是物理资源发送了改变。
这样，在选择的资源种类发生改变或者选择的资源种类没有改变但是物理资源改变的情况下，不提升功率，能够减少用户设备的不必要的功率消耗。
在步骤201中，根据选择的SSB和CSI-RS资源中任一个的变化情况，确定是否提升目标接收功率，在确定了目标接收功率是否提升之后，该方法还可以包括：
步骤203：根据是否提升目标接收功率，确定与功率提升相关的计数器是否加1；
步骤204：在确定提升目标接收功率的情况下，将与功率提升相关的计数器加1；以及
步骤205：在确定不提升目标接收功率的情况下，维持与功率提升相关的计数器不变。
在步骤203-205中，提升目标接收功率可以通过各种方法实现，例如，提升目标接收功率可以通过与功率相关的计数器加1来实现。根据是否提升目标接收功率，确定与功率提升相关的计数器是否加1，并根据确定的结果将该计数器加1或将该计数器维持不变。
也就是说，根据是否提升目标接收功率，维护与功率提升相关的计数器，实现目标接收功率的提升与不提升，当该计数器加1时，则实现目标接收功率的提升，当该计数器不变时，则实现目标接收功率的不提升。
在本实施例中，也可以是，在步骤201中，根据选择的SSB和CSI-RS资源中任一个的变化情况，直接确定功率相关的计数器是否加1。例如，可以是选择的SSB和CSI-RS资源中任一个发生改变，计数器维持不变，否则，计数器加1。
也就是说，可以根据选择的SSB和CSI-RS资源中任一个的变化情况，确定与功率相关的计数器是否加1。
在本实施例中，与功率提升相关的计数器，可以是一个SSB和CSI-RS资源共用的功率提升相关的计数器，例如PREAMBLE_POWER_RAMPING_COUNTER；也可以是SSB专用的与功率提升相关的计数器，例如，PREAMBLE_POWER_RAMPING_COUNTER_SSB，和/或，CSI-RS资源专用的与功率提升相关的计数器，例如，PREAMBLE_POWER_RAMPING_COUNTER_CSIRS。其中，使用何种计数器可以由网络设备侧进行配置。
例如，在确定提升目标接收功率的情况下，
当配置的是SSB和CSI-RS资源共用的与功率提升相关的计数器时，将SSB和CSI-RS资源共用的与功率提升相关的计数器加1，
当配置的是SSB专用的与功率提升相关的计数器和/或CSI-RS资源专用的与功率提升相关的计数器时，在当前选择的是SSB的情况下，将SSB专用的与功率提升相关的计数器加1，在当前选择的是CSI-RS资源的情况下，将CSI-RS资源专用的与 功率提升相关的计数器加1。
在本实施例中，通过上述步骤203-205，对与功率提升相关的计数器完成了维护，此后，该方法还可以包括：
步骤206：根据与功率提升相关的计数器的数值与预设值的差值与预设步长的乘积、目标接收功率初始值以及前导码参数，计算目标接收功率。
在步骤206中，根据用户设备使用的与功率提升相关的计数器的不同，计算目标接收功率的方法也可以不同。
例如，在使用的是SSB和CSI-RS资源共用的与功率提升相关的计数器的情况下，可以根据以下的公式(1)计算目标接收功率：
目标接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+
(PREAMBLE_POWER_RAMPING_COUNTER–1)×preamblePowerRampingStep(1)
其中，preambleReceivedTargetPower表示目标接收功率初始值，DELTA_PREAMBLE表示前导码参数，PREAMBLE_POWER_RAMPING_COUNTER表示SSB和CSI-RS资源共用的与功率提升相关的计数器的数值，1表示预设值为1，preamblePowerRampingStep表示预设步长。
在本实施例中，目标接收功率初始值、前导码参数以及预设步长可以是网络设备侧预先配置的。
例如，在使用的是SSB专用的与功率提升相关的计数器和/或CSI-RS资源专用的与功率提升相关的计数器的情况下，可以根据以下的公式(2)计算目标接收功率：
目标接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER_SSB+PREAMBLE_POWER_RAMPING_COUNTER_CSIRS–k)×preamblePowerRampingStep
                                                (2)
其中，preambleReceivedTargetPower表示目标接收功率初始值，DELTA_PREAMBLE表示前导码参数，PREAMBLE_POWER_RAMPING_COUNTER_SSB表示SSB专用的与功率提升相关的计数器的数值，PREAMBLE_POWER_RAMPING_COUNTER_CSIRS表示CSI-RS资源专用的与功率提升相关的计数器的数值，k表示预设值为k，preamblePowerRampingStep表示预设步长。
在本实施例中，目标接收功率初始值、前导码参数以及预设步长可以是网络设备侧预先配置的。
在本实施例中，在网络设备配置的是SSB专用的与功率提升相关的计数器和CSI-RS资源专用的与功率提升相关的计数器的情况下，用户设备可以使用这两个计数器，也可以使用其中的一个。
在本实施例中，在使用SSB专用的与功率提升相关的计数器和/或CSI-RS资源专用的与功率提升相关的计数器的情况下，该预设值可以根据使用的资源专用的与功率提升相关的计数器的数量、SSB专用的与功率提升相关的计数器的初始值和/或CSI-RS资源专用的与功率提升相关的计数器的初始值确定。
例如，以下列举了一些示例性的情况。
1)仅使用了SSB专用的与功率提升相关的计数器，且该计数器的初始值为1，则该预设值为1；
2)仅使用了CS-RS资源专用的与功率提升相关的计数器，且该计数器的初始值为1，则该预设值为1；
3)使用了SSB专用的与功率提升相关的计数器，也使用了CS-RS资源专用的功率提升相关的计数器，且两个计数器的初始值均为1，则该预设值为2；
4)仅使用了SSB专用的与功率提升相关的计数器，且该计数器的初始值为0，则该预设值为0；
5)仅使用了CS-RS资源专用的与功率提升相关的计数器，且该计数器的初始值为0，则该预设值为0；
6)使用了SSB专用的与功率提升相关的计数器，也使用了CS-RS资源专用的与功率提升相关的计数器，且两个计数器的初始值均为0，则该预设值为0；
7)使用了SSB专用的与功率提升相关的计数器，且该计数器的初始值为0；也使用了CS-RS资源专用的与功率提升相关的计数器，且该计数器的初始值为1，则该预设值为1；
8)使用了SSB专用的与功率提升相关的计数器，且该计数器的初始值为1；也使用了CS-RS资源专用的与功率提升相关的计数器，且该计数器的初始值均为0，则该预设值为1。
在步骤206中，还可以使用SSB和CSI-RS资源共用的参数，或者，SSB或CSI- RS资源专用的参数来计算目标接收功率。
例如，可以根据与功率提升相关的计数器的数值与预设值的差值与SSB或CSI-RS资源专用或两者共用的预设步长的乘积、SSB或CSI-RS资源专用或两者共用的目标接收功率初始值以及SSB或CSI-RS资源专用或两者共用的前导码参数，计算目标接收功率。
例如，无论当前选择的是SSB还是CSI-RS资源，都根据以上的公式(1)计算目标接收功率。
又例如，使用与当前选择的资源所专用的参数计算目标接收功率。
例如，在当前选择的是SSB的情况下，可以使用以下的公式(3)计算目标接收功率：
目标接收功率＝
preambleReceivedTargetPower_SSB+DELTA_PREAMBLE_SSB+(PREAMBLE_POWER_RAMPING_COUNTER–1)×preamblePowerRampingStep_SSB
                             (3)
其中，preambleReceivedTargetPower_SSB表示SSB专用的目标接收功率初始值，DELTA_PREAMBLE_SSB表示SSB专用的前导码参数，PREAMBLE_POWER_RAMPING_COUNTER表示与功率提升相关的计数器的数值，1表示预设值为1，preamblePowerRampingStep_SSB表示SSB专用的预设步长。
在本实施例中，SSB专用的目标接收功率初始值、前导码参数以及预设步长可以是网络设备侧预先配置的。
例如，在当前选择的是CSI-RS的情况下，可以使用以下的公式(4)计算目标接收功率：
目标接收功率＝
preambleReceivedTargetPower_CSIRS+DELTA_PREAMBLE_CSIRS+(PREAMBLE_POWER_RAMPING_COUNTER–1)×preamblePowerRampingStep_CSIRS
                                     (4)
其中，preambleReceivedTargetPower_CSIRS表示CSI-RS资源专用的目标接收功率初始值，DELTA_PREAMBLE_CSIRS表示CSI-RS资源专用的前导码参数，PREAMBLE_POWER_RAMPING_COUNTER表示与功率提升相关的计数器的数值，1 表示预设值为1，preamblePowerRampingStep_CSIRS表示CSI-RS资源专用的预设步长。
在本实施例中，CSI-RS资源专用的目标接收功率初始值、前导码参数以及预设步长可以是网络设备侧预先配置的。
在本实施例中，上述步骤202-206是可选步骤。
图3是本发明实施例1的功率的确定方法的另一示意图。如图3所示，该方法包括：
步骤301：根据是否改变空域发送滤波器，确定是否发送与功率提升相关的计数器的挂起指示；
步骤302：根据选择的SSB和CSI-RS资源中任一个的变化情况以及是否接收到与功率提升相关的计数器的挂起指示，确定是否提升目标接收功率。
在步骤301中，当物理层改变空域发送滤波器时，则向MAC层发送与功率提升相关的计数器的挂起指示，当物理层没有改变空域发送滤波器时，则不发送该挂起指示。
在步骤302中，当MAC层接收到该挂起指示时，则保持与功率提升相关的计数器不变，即不提升目标接收功率，当MAC层没有接收到该挂起指示时，根据选择的SSB和CSI-RS资源中任一个的变化情况确定是否提升目标接收功率，具体的确定方法与图2的步骤201相同，此处不再赘述。
在本实施例中，该方法还可以包括：
步骤303：根据选择的SSB或CSI-RS资源，或者，根据选择的SSB或CSI-RS资源所对应的随机接入资源和随机接入前导码的索引，确定是否改变空域发送滤波器。
在本实施例中，步骤303是可选步骤。
例如，在随机接入前导码重传的情况下，或者，在随机接入前导码初传或重传的情况下，并且，在MAC层开始执行随机接入前导码传输过程前，MAC层将选择的SSB的索引或选择的CSI-RS资源的ID或与选择的CSI-RS资源准共置的SSB的索引发送给物理层，或者，MAC层将选择的SSB或CSI-RS资源所对应的随机接入资源和随机接入前导码的索引发送给物理层。
另外，如果MAC层已经完成了随机接入前导码传输过程，则可以不再向物理层提供上述信息，仅提供目标接收功率，另外，如果有RA-RNTI的情况下也提供该信 息。
这样，能够解决现有技术中存在以下的问题：在上行无线状况与下行无线状况存在互易性的情况下，空域发送滤波器与MAC层选择的资源存在关联。基于当前物理层与MAC层之间的交互，物理层确定空域发送滤波器时，不知道MAC层资源选择的结果。这可能导致物理层错误地为MAC层提供了挂起指示，或错误地没有为MAC层提供挂起指示，从而导致功率是否提升的决定错误。
也就是说，能够合理的为MAC层提供挂起指示，从而合理的决定是否进行功率提升。
由上述实施例可知，根据选择的SSB和CSI-RS资源中任一个的变化情况，确定是否提升目标接收功率，从而考虑了选择CSI-RS资源的情况，能够在必要的情况下进行功率提升并避免无用的重传，从而提高了随机接入的成功率并减少了UE的功率消耗。

步骤402：在选择的SSB发生改变以外的其他情况下，确定提升目标接收功率。
在本实施例中，在确定选择的CSI-RS资源是否发生改变时，没有考虑CSI-RS资源与SSB的准共置关系。
在本实施例中，选择的SSB发生改变表示当前选择的是SSB，对于选择的SSB发生改变的情况，可以参见实施例1中的记载。
例如，选择的SSB发生改变的情况可以包括以下情况中的任一个：
1)当前选择的是SSB，前一次选择的是SSB，但是这两个SSB不同；
2)当前选择的是SSB，前一次选择的是CSI-RS；
3)当前选择的是SSB，且当前选择的SSB与之前选择的所有SSB均不同。
在本实施例中，实现提升目标接收功率和不提升目标接收功率的方法可以和实施例1中的记载相同，即，根据是否提升目标接收功率，确定与功率提升相关的计数器是否加1，并根据确定的结果将该计数器加1或将该计数器维持不变。
另外，使用何种计数器或使用何种参数来计算目标接收功率的具体方法可以与实施例1中的记载相同，此处不再赘述。
另外，本实施例的方法也可以包括确定计数器的挂起指示，以及，根据选择的SSB和CSI-RS资源中任一个的变化情况以及是否接收到挂起指示确定是否提升目标接收功率的步骤，具体的实现方法与实施例1中的记载相同，此处不再赘述。
由上述实施例可知，根据选择的SSB和CSI-RS资源中任一个的变化情况，确定是否提升目标接收功率，从而考虑了选择CSI-RS资源的情况，能够在必要的情况下进行功率提升并避免无用的重传，从而提高了随机接入的成功率并减少了UE的功率消耗。另外，对于当前选择了CSI-RS资源且没有改变的情况可以进行合理的处理，即进行功率提升。
实施例3
本发明实施例还提供了一种功率的确定方法，该方法应用于用户设备侧。
图5是本发明实施例3的功率的确定方法的一示意图。如图5所示，该方法包括：
步骤501：在选择的SSB和CSI-RS资源中的任一个没有发生改变的情况下，确定提升目标接收功率；
步骤502：在选择的SSB和CSI-RS资源中的任一个没有发生改变的情况以外的其他情况下，确定不提升目标接收功率。
在本实施例中，在确定选择的CSI-RS资源是否发生改变时，没有考虑CSI-RS资源与SSB的准共置关系。
在本实施例中，对于选择的SSB和CSI-RS资源中的任一个没有发生改变的情况，可以参见实施例1中的记载。
例如，选择的SSB和CSI-RS资源中的任一个没有发生改变的情况可以包括以下情况中的任一个：
1)当前选择了SSB，前一次选择了SSB，且两者相同；
2)当前选择了SSB，当前选择的SSB与之前选择的SSB中的至少一个SSB相同；
3)当前选择了CSI-RS，前一次选择了CSI-RS，且两者相同；
4)当前选择了CSI-RS，当前选择的CSI-RS与之前选择的CSI-RS中的至少一个 CSI-RS相同。
在本实施例中，实现提升目标接收功率和不提升目标接收功率的方法可以和实施例1中的记载相同，即，根据是否提升目标接收功率，确定与功率提升相关的计数器是否加1，并根据确定的结果将该计数器加1或将该计数器维持不变。
另外，使用何种计数器或使用何种参数来计算目标接收功率的具体方法可以与实施例1中的记载相同，此处不再赘述。
另外，本实施例的方法也可以包括确定计数器的挂起指示，以及，根据选择的SSB和CSI-RS资源中任一个的变化情况以及是否接收到挂起指示确定是否提升目标接收功率的步骤，具体的实现方法与实施例1中的记载相同，此处不再赘述。
以下，针对切换的场景对本实施例的方法进行示例性的说明。
在切换的情况下，网络设备可能只为用户设备提供了CSI-RS资源相对应的专用随机接入资源和随机接入前导码。在这种情况下，满足无线链路质量条件的CSI-RS资源会被优先选择，这样，在所有的资源选择过程中，只有CSI-RS资源会被选择，没有选择SSB是常规情况。
例如，在随机接入前导码初传时，CSI-RS resource ID＝3的CSI-RS资源被选择。在第一次随机接入前导码重传时，CSI-RS resource ID＝4的CSI-RS资源被选择，则与功率相关计数器保持不变。在第二次随机接入前导码重传时，CSI-RS resource ID＝3的CSI-RS资源被选择，如果仅与上一次传输相比较，则与功率相关计数器保持不变；如果考虑所有传输，则功率相关计数器加1。
此外，在切换的情况下，在进行某次资源选择时，如果所有配置了专用随机接入资源的CSI-RS资源都不满足无线链路质量条件，那么可选择SSB所对应的公共随机接入资源进行随机接入前导码的重传。
例如，在随机接入前导码初传时，CSI-RS resource ID＝3的CSI-RS被选择。在第一次随机接入前导码重传时，CSI-RS resource ID＝4的CSI-RS被选择，则与功率相关计数器保持不变。在第二次随机接入前导码重传时，SSB index＝1的SSB被选择，与功率相关计数器保持不变。
由上述实施例可知，根据选择的SSB和CSI-RS资源中任一个的变化情况，确定是否提升目标接收功率，从而考虑了选择CSI-RS资源的情况，能够在必要的情况下进行功率提升并避免无用的重传，从而提高了随机接入的成功率并减少了UE的功率 消耗。另外，对于当前与之前选择了同一种资源的情况，例如都选择了SSB或都选择了CSI-RS资源，可以进行合理的处理。

步骤601：在选择的SSB和CSI-RS资源中的任一个发生改变的情况下，确定不提升目标接收功率；
步骤602：在选择的SSB和CSI-RS资源中的任一个发生改变的情况以外的其他情况下，确定提升目标接收功率。
在本实施例中，在确定选择的CSI-RS资源是否发生改变时，没有考虑CSI-RS资源与SSB的准共置关系。
在本实施例中，选择的SSB和CSI-RS资源中的任一个发生改变的情况可以参见实施例1中的记载。
例如，选择的SSB和CSI-RS资源中的任一个发生改变的情况可以包括以下情况中的任一个：
1)当前选择的是SSB，前一次选择的是SSB，但是这两个SSB不同；
2)当前选择的是SSB，且当前选择的SSB与之前选择的所有SSB均不同；
3)当前选择的是CSI-RS资源，前一次选择的是CSI-RS，但是这两个CSI-RS资源不同；
4)当前选择的是CSI-RS资源，且当前选择的CSI-RS资源与之前选择的所有CSI-RS资源均不同。
在本实施例中，实现提升目标接收功率和不提升目标接收功率的方法可以和实施例1中的记载相同，即，根据是否提升目标接收功率，确定与功率提升相关的计数器是否加1，并根据确定的结果将该计数器加1或将该计数器维持不变。

另外，本实施例的方法也可以包括确定计数器的挂起指示，以及，根据选择的SSB和CSI-RS资源中任一个的变化情况以及是否接收到挂起指示确定是否提升目标接收 功率的步骤，具体的实现方法与实施例1中的记载相同，此处不再赘述。
以下，针对切换的场景对本实施例的方法进行示例性的说明。
在切换的情况下，网络设备可能只为用户设备提供CSI-RS资源相对应的专用随机接入资源和随机接入前导码。在这种情况下，满足无线链路质量条件的CSI-RS资源会被优先选择，这样，在所有资源选择过程中，只有CSI-RS资源被选择，没有选择SSB是常规情况。
在随机接入前导码初传时，CSI-RS resource ID＝3的CSI-RS资源被选择。在第一次随机接入前导码重传时，CSI-RS resource ID＝4的CSI-RS资源被选择，则与功率相关的计数器保持不变。在第二次随机接入前导码重传时，CSI-RS resource ID＝3的CSI-RS资源被选择，如果仅与上一次传输相比较，则与功率相关的计数器保持不变；如果考虑所有传输，则与功率相关的计数器加1。
此外，在切换的情况下，在某次资源选择时，若所有配置了专用随机接入资源的CSI-RS都不满足无线链路质量条件，那么可选择SSB所对应的公共随机接入资源进行随机接入前导码的重传。
例如，在随机接入前导码初传时，CSI-RS resource ID＝3的CSI-RS资源被选择。在第一次随机接入前导码重传时，CSI-RS resource ID＝4的CSI-RS资源被选择，则与功率相关的计数器保持不变。在第二次随机接入前导码重传时，SSB index＝1的SSB被选择，与功率相关的计数器加1。
由上述实施例可知，根据选择的SSB和CSI-RS资源中任一个的变化情况，确定是否提升目标接收功率，从而考虑了选择CSI-RS资源的情况，能够在必要的情况下进行功率提升并避免无用的重传，从而提高了随机接入的成功率并减少了UE的功率消耗。另外，对于当前与之前选择了同一种资源的情况，例如都选择了SSB或都选择了CSI-RS资源，可以进行合理的处理。

步骤701：在选择的SSB发生改变或与选择的CSI-RS资源准共置的SSB发生改变的情况下，确定不提升目标接收功率；
步骤702：在选择的SSB发生改变和与选择的CSI-RS资源准共置的SSB发生改变的情况以外的其他情况下，确定提升目标接收功率。
在本实施例中，在确定选择的CSI-RS资源是否发生改变时，考虑了CSI-RS资源与SSB的准共置关系。
在本实施例中，选择的SSB发生改变和与选择的CSI-RS资源准共置的SSB发生改变的情况可以参见实施例1中的记载。

以下，对步骤701和步骤702的具体实现方式进行示例性的说明。
在步骤701中，例如，在当前选择的SSB和前一次选择的SSB不同的情况下，或者，在当前选择的SSB和之前选择的所有SSB均不同的情况下，或者，在当前选择的SSB和与前一次选择的CSI-RS资源准共置的SSB不同的情况下，或者，在当前选择的SSB和与之前选择的所有CSI-RS资源准共置的SSB不同的情况下，或者，在当前选择的SSB和之前选择的所有SSB不同，且当前选择的SSB和与之前选择的所有CSI-RS资源准共置的SSB不同的情况下，或者，在与当前选择的CSI-RS资源准共置的SSB与前一次选择的SSB不同的情况下，或者，在与当前选择的CSI-RS资 源准共置的SSB与之前选择的所有SSB不同的情况下，或者，在与当前选择的CSI-RS资源准共置的SSB和与前一次选择的CSI-RS资源准共置的SSB不同的情况下，或者，在与当前选择的CSI-RS资源准共置的SSB和与之前选择的所有CSI-RS资源准共置的SSB不同的情况下，或者，在与当前选择的CSI-RS资源准共置的SSB与之前选择的所有SSB不同，且与当前选择的CSI-RS资源准共置的SSB和与之前选择的所有CSI-RS资源准共置的SSB不同的情况下，或者，在当前选择的CSI-RS资源与前一次选择的CSI-RS资源不同，且与当前选择的CSI-RS资源准共置的SSB与前一次选择的CSI-RS资源准共置的SSB相同的情况下，或者，在当前选择的CSI-RS资源与之前选择的所有CSI-RS资源均不同，且与当前选择的CSI-RS资源准共置的SSB与之前选择的至少一个CSI-RS资源准共置的SSB相同的情况下，或者，在与当前选择的CSI-RS资源准共置的SSB与之前选择的所有SSB均不同，且与之前选择的所有CSI-RS均不同，且与当前选择的CSI-RS资源准共置的SSB和与之前选择的所有CSI-RS资源准共置的SSB均不同的情况下，或者，在与当前选择的CSI-RS资源准共置的SSB与之前选择的所有SSB均不同，且与之前选择的所有CSI-RS均不同，且与当前选择的CSI-RS资源准共置的SSB和与之前选择的至少一个CSI-RS资源准共置的SSB相同的情况下，确定不提升目标接收功率。
在步骤702中，例如，在当前选择的SSB和前一次选择的SSB相同的情况下，或者，在当前选择的SSB和之前选择的所有SSB中至少一个相同的情况下，或者，在当前选择的SSB和与前一次选择的CSI-RS资源准共置的SSB相同的情况下，或者，在当前选择的SSB和与之前选择的所有CSI-RS资源准共置的SSB中的至少一个相同的情况下，或者，在当前选择的CSI-RS资源与前一次选择的CSI-RS资源相同的情况下，或者，在当前选择的CSI-RS资源和之前选择的所有CSI-RS资源中至少一个相同的情况下，或者，在当前选择的CSI-RS资源与前一次选择的CSI-RS资源不同，且与当前选择的CSI-RS资源准共置的SSB和与前一次选择的CSI-RS资源准共置的SSB相同的情况下，或者，在当前选择的CSI-RS资源与之前选择的所有CSI-RS资源均不同，且与当前选择的CSI-RS资源准共置的SSB和与之前选择的所有CSI-RS资源准共置的SSB中的至少一个相同的情况下，或者，在与当前选择的CSI-RS资源准共置的SSB和前一次选择的SSB相同的情况下，或者，在与当前选择的CSI-RS资源准共置的SSB和之前选择的所有SSB中的至少一个相同的情况下， 或者，在与当前选择的CSI-RS资源准共置的SSB与之前选择的所有SSB均不同，且与之前选择的所有CSI-RS均不同，且与当前选择的CSI-RS资源准共置的SSB和与之前选择的至少一个CSI-RS资源准共置的SSB相同的情况下，确定提升目标接收功率。
在本实施例中，实现提升目标接收功率和不提升目标接收功率的方法可以和实施例1中的记载相同，即，根据是否提升目标接收功率，确定与功率提升相关的计数器是否加1，并根据确定的结果将该计数器加1或将该计数器维持不变。
另外，使用何种计数器或使用何种参数来计算目标接收功率的具体方法可以与实施例1中的记载相同，此处不再赘述。
另外，本实施例的方法也可以包括确定计数器的挂起指示，以及，根据选择的SSB和CSI-RS资源中任一个的变化情况以及是否接收到挂起指示确定是否提升目标接收功率的步骤，具体的实现方法与实施例1中的记载相同，此处不再赘述。
以下，针对随机接入过程是由于波束失败恢复而被触发的场景对本实施例的方法进行示例性的说明。
当随机接入过程是由于波束失败恢复而被触发时，网络设备可能为波束失败恢复同时配置了CSI-RS和SSB对应的专用随机接入资源，也配置了与其中部分或所有CSI-RS资源准共置的SSB。
例如，随机接入前导码初传时，MAC层选择了SSB index＝1的SSB所对应的随机接入资源；当随机接入前导码第一次重传时，MAC子层选择了CSI-RS resource ID＝3(其与SSB index＝1的SSB准共置)的CSI-RS资源，即可认为选择的CSI-RS资源没有改变，功率提升相关的计数器加1。
由上述实施例可知，根据选择的SSB和CSI-RS资源中任一个的变化情况，确定是否提升目标接收功率，从而考虑了选择CSI-RS资源的情况，能够在必要的情况下进行功率提升并避免无用的重传，从而提高了随机接入的成功率并减少了UE的功率消耗。另外，由于考虑了CSI-RS资源与SSB的准共置关系，从而不管当前选择了何种资源，都可以进行合理的处理
实施例6
本发明实施例还提供了一种功率的确定方法，该方法应用于网络设备侧，其对应于实施例1-5的应用于用户设备侧的功率的确定方法。
图8是本发明实施例6的功率的确定方法的一示意图。如图8所示，该方法包括：
步骤801：向用户设备配置SSB和CSI-RS资源共用的与功率提升相关的计数器，或者，SSB专用的与功率提升相关的计数器和CSI-RS资源专用的与功率提升相关的计数器；和/或
步骤802：向用户设备配置用于计算目标接收功率的SSB和CSI-RS资源共用的参数，或者，用于计算目标接收功率的SSB专用的参数和CSI-RS资源专用的参数。
例如，用于计算目标接收功率的SSB专用的参数包括以下参数中的至少一个：SSB专用的预设步长、SSB专用的目标接收功率初始值以及SSB专用的前导码参数，
用于计算目标接收功率的CSI-RS资源专用的参数包括以下参数中的至少一个：CSI-RS资源专用的预设步长、CSI-RS资源专用的目标接收功率初始值以及CSI-RS资源专用的前导码参数。
在本实施例中，网络设备向用户设备按照上述步骤配置与功率提升相关的计数器和/或用于计算目标接收功率的参数，以使得用户设备能够根据该配置来使用相关的计数器以及参数计算目标接收功率，具体的计算方法可参见实施例1中的记载，此处不再赘述。
在本实施例中，例如，该方法还可以包括：
步骤803：向用户设备配置当确定选择的CSI-RS资源是否改变时是否考虑CSI-RS资源与SSB准共置的关系的规则；和/或
步骤804：向用户设备配置在考虑了CSI-RS资源与SSB准共置的关系的情况下确定选择的CSI-RS资源是否改变的规则和/或CSI-RS资源与SSB准共置的关系。
例如，当前选择的是CSI-RS资源，前一次选择的也是CSI-RS资源，这两个CSI-RS资源不同，但是，与当前选择的CSI-RS资源准共置的SSB与前一次选择的CSI-RS资源准共置的SSB相同，当考虑了CSI-RS资源与SSB的准共置关系时，可以确定为选择的CSI-RS资源没有改变，或者，也可以确定为选择的CSI-RS资源发生了改变，而确定是否发生了改变由该配置的规则进行规定；当没有考虑CSI-RS资源与SSB的准共置关系时，可以确定为选择的CSI-RS资源发生了改变。
又例如，当前选择的是CSI-RS资源，当前选择的CSI-RS资源与之前选择过的所有CSI-RS资源都不相同，但是，当前选择的CSI-RS资源准共置的SSB和与之前 选择过的所有CSI-RS资源中的至少一个CSI-RS资源准共置的SSB相同，当考虑了CSI-RS资源与SSB的准共置关系时，可以确定为选择的CSI-RS资源没有改变，或者，也可以确定为选择的CSI-RS资源发生了改变，而确定是否发生了改变由该配置的规则进行规定；当没有考虑CSI-RS资源与SSB的准共置关系时，可以确定为选择的CSI-RS资源发生了改变。
在本实施例中，该准共置的关系可以通过RRC专用信令进行配置。
另外，该准共置的关系可以通过测量对象配置而进行配置，和/或，该准共置的关系可以和候选波束一起进行配置。
在本实施例中，该CSI-RS资源与SSB准共置的关系可以包括：CSI-RS资源与任意的SSB准共置；或者，CSI-RS资源与所有的SSB都不存在准共置的关系；或者，CSI-RS资源与预定义或预配置的至少一个SSB准共置。
在本实施例中，对上述步骤801-804的执行顺序不作限制。
由上述实施例可知，通过向用户设备配置与SSB和/或CSI-RS资源相关的、与功率提升相关的计数器和/或用于计算目标接收功率的参数，用户设备能够根据该配置，并根据选择的SSB和CSI-RS资源中任一个的变化情况，确定是否提升目标接收功率，从而考虑了选择CSI-RS资源的情况，能够在必要的情况下进行功率提升并避免无用的重传，从而提高了随机接入的成功率并减少了UE的功率消耗。
