接下来，对子带非重叠全双工(SubBand non-overlapping Full Duplex，SBFD)进行介绍：
为了克服时分双工(Time Division Duplexing，TDD)技术中，上行(Uplink，UL)资源分配较少导致的上行覆盖较弱、上行时延大、上行容量不够等问题，SBFD技术被提出。SBFD技术指在同一个子帧或同一个时隙或同一个符号的不同子带上可以同时发送数据和接收数据的技术。SBFD技术主要用于网络设备侧，终端设备(User Equipment，UE)侧仍保持当前状态，即同一个子帧/时隙/符号只发送数据或只接收数据。SBFD技术也可以被称为交叉双工(Cross Division Duplex，XDD)技术。
示例性的，SBFD技术如图1所示，将一个下行(Downlink，DL)时域单元对应的频域资源的一部分配置为上行子带。如图1的(a)部分所示，一个下行时域单元对应的频域资源的中间子带被配置为上行 子带，或者，如图1的(b)部分所示，一个下行时域单元对应的频域资源的上部分子带被配置为上行子带。
一般来说，SBFD操作满足以下几点：
·SBFD在一个TDD载波内操作。
·SBFD方案设计在具有对齐的中心频点的单一上下行BWP(Bandwidth Part，部分带宽)对内。
·在一个TDD载波内，一个SBFD符号(包括传统上行符号)上最多有一个上行子带。这一个上行子带可以位于TDD载波的中间，也可以位于TDD载波的两边。此外，协议约定上行传输只能限制在UL子带内，下行接收只能限制在DL子带内。
接下来，对物理随机接入信道(Physical Random Access Channel，PRACH)进行介绍：
PRACH相关参数通过随机接入通用配置(RACH-ConfigGeneric)来配置，接下来从时域资源配置、频域资源配置和功率控制三个方面对RACH-ConfigGeneric中的参数进行说明。
PRACH时域资源配置：
在5G NR中，随机接入信道对应的时域资源是根据PRACH配置表格确定的，其中，存在三个PRACH配置表格，分别对应不同的频段和频段制式：PRACH配置表格1为FR1(Frequency Range 1，频段1)上FDD(Frequency Division Duplexing，频分双工)频段的PRACH配置，PRACH配置表格2为FR1上TDD频段的PRACH配置，PRACH配置表格3为FR2上的PRACH配置。终端设备会根据其驻留的小区所处的频段和频段制式，确定在接收PRACH配置时应该使用的PRACH配置表格。
在为终端设备配置小区随机接入信道对应的时域资源时，通过物理随机接入信道-配置索引(prach-ConfigurationIndex)这一相关参数指示出相应的PRACH配置表格中的一个序号。终端按照相应的PRACH配置表格，获取该小区的PRACH时域资源配置信息，该时域资源配置信息包括：
1.PRACH序列的格式：在FR1上会配置所有长、短序列格式，在FR2上仅会配置短序列格式。
2.配置周期和系统帧号：PRACH传输机会的重复周期和所在的系统帧号，NR中支持10ms，20ms，40ms，80ms和160ms的周期配置。
3.子帧/时隙序号：PRACH传输机会在系统帧内出现的子帧号或时隙的序号；其中，FR1上指示的是子帧号，也是15KHz时隙的序号；在FR2上则是按60KHz时隙序号指示。
4.对于短序列，还会配置出在一个子帧或是一个60KHz时隙中有几个PRACH时隙，当随机接入序列配置了更大的子载波间隔时，一个子帧或是一个60KHz时隙中会有2个PRACH时隙，当指示值为2时，2个PRACH时隙均可使用；指示有1个PRACH时隙时，默认使用靠后的PRACH时隙。
5.起始符号和持续次数：在一个PRACH时隙内PRACH传输机会(PRACH transmission occasion)的起始位置和持续次数，持续次数即连续出现的次数。即使在相同的序列格式、相同周期和相同时隙号的配置下，也可以有不同的起始位置和持续次数配置，这样能够提供更多样的PRACH密度配置。
PRACH功率控制：
PRACH的功率控制采用开环功率控制的机制，UE基于网络设备配置的期望接收功率以及由下行参考信号测量得到的路径损耗等因素设定PRACH的发送功率：
终端通过以下公式确定PRACH的发送功率：
PPRACH，b，f，c(i)＝min{PCMAX，f，c(i)，PPRACH，target，f，c+pLb，f，c}[dBm]
其中，f为载波(carrier)；c为服务小区(serving cell)；b为BWP；i为PRACH传输机会；PCMAX， f，c(i)为UE配置的最大输出功率；PPRACH，target，f，c为前导目标功率；PLb，f，c为路径损耗。
目标接收功率PREAMBLE_RECEIVED_TARGET_POWER(简称为接收功率)的计算公式如下所示。
PREAMBLE_RECEIVED_TARGET_POWER＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP
其中，目标功率等级(preambleReceivedTargetPower，简称为功率等级)是通过RRC(Radio Resource Control，无线资源控制)信令配置的；前导码增量(DELTA_PREAMBLE)为基于随机接入前导码格式、使用的子载波间隔、协议约定的固定值中的至少之一确定；功率爬升计数器(PREAMBLE_POWER_RAMPING_COUNTER)，也可以称为前导功率爬升次数，是根据功率爬升计数器确定的，在每次随机接入过程开始时，初始化为1，每次重传，功率爬升计数器加1；功率爬升步长(PREAMBLE_POWER_RAMPING_STEP)，也可以称为前导功率爬升步长，用于指示功率爬升的步长。
在随机接入过程中，若UE发送了PRACH但未接收到网络的RAR(Random Access Response，随机接入响应)响应或没有成功接收到冲突解决消息，那么UE需要重发PRACH。当NR UE支持多个发射波束时，在进行重传时，若发射波束保持不变，则重传的PRACH接收功率在上一次发送的PRACH接收功率的基础上进行爬升，可以理解为重传次数加1，也可以理解为功率爬升计数器加1，直至成功完成随机接入过程。但在UE切换发射波束时，综合考虑波束切换时的干扰控制和随机接入的时延，协议约定功率 爬升计数器保持不变。如图2所示，斜线椭圆11表示本次传输使用的发射波束，虚线椭圆12表示本次传输未被使用的发射波束，在初传、第一次重传以及第二次重传时，使用的发射波束为同一个，因此，在进行重传时功率爬升计数器加1；而在第三次重传时，使用的发射波束相较于上一次传输所使用的发射波束发生改变，因此，第三次重传时功率爬升计数器不变；在第四次重传时，使用的发射波束未发生改变，功率爬升计数器加1。
当PRACH传输次数达到RRC配置的参数preambleTransMax(前导码传输最大次数，也可以称为随机接入前导码的最大传输次数)时，则向高层指示随机接入问题，或者认为随机接入过程不成功。
也即，在随机接入过程开始时，MAC(Medium Access Control，媒体访问控制)层初始化功率爬升计数器以及随机接入前导码传输计数器为1，如果UE发送了PRACH但未接收到网络的RAR响应或没有成功接收到冲突解决消息，随机接入前导码传输计数器+1(表示UE需要重传PRACH)，如果随机接入前导码传输计数器大于1，则功率爬升计数器+1，这样一来，设置功率时，由于PREAMBLE_RECEIVED_TARGET_POWER＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP，所以自然实现了PRACH重传的功率爬升以及PRACH传输次数的计数。
在SBFD符号中的随机接入信道传输：
目前，协议约定对于RRC IDLE(空闲)/INACTIVE(去激活)/CONNECTED(连接，也可以称为激活，即ACTIVE)状态下，都在SBFD符号支持RACH传输，且支持两种RACH配置选项：选项1即对于SBFD-aware UE(支持SBFD的UE)和legacy UE(传统UE)复用同一套RACH configuration(随机接入信道配置)，例如都使用rach-ConfigCommon(公共RACH配置)中配置的RO；选项2即定义separate RACH configuration(独立的RACH配置)，一套legacy RACH configuration(传统RACH配置)，一套additional RACH configuration(附加RACH配置)。不管是哪个选项，对于SBFD-aware UE，都会识别两种类型的RACH occasion(RO，随机接入时机/随机接入传输机会/随机接入信道传输机会，简称为传输机会)，legacy RO(传统RO，例如选项1中UL symbol(上行符号)和flexible symbol(灵活符号)中的RO，选项2中legacy RACH configuration配置的RO)和additional RO(附加RO，例如选项1中SBFD-Dsymbol(即在上下行公共配置信令中被配置为下行链路的SBFD符号)中的RO，选项2中additional RACH configuration配置的RO)。
其中，rach-ConfigCommon用于配置基于非竞争的随机接入和基于竞争的随机接入以及基于竞争的随机接入失败后的重传的BWP。在采用选项2时，legacy RACH configuration即为传统使用的配置，也即当前协议中设定的rach-ConfigCommon，additional RACH configuration是为SBFD操作设定的配置，即在rach-ConfigCommon的基础上的额外配置。

接下来将对第一类型传输机会和第二类型传输机会做简单介绍。
在一些实施例中，第一类型传输机会是非SBFD符号关联的RO，第二类型传输机会是SBFD符号关联的RO。也可以说，第一类型传输机会是非SBFD时域资源关联的RO，第二类型传输机会是SBFD时域资源关联的RO。时域资源包括如下至少之一：符号、符号组、时隙、子时隙、帧、子帧。本申请实施例中对时域资源的具体类型不加以限定。其中，SBFD符号为包括上行子带、下行子带、保护带中至少之一的符号，non-SBFD符号(即非SBFD符号)为不包括以上子带的符号。也即，上述“第一变量用于随机接入信道在第一类型传输机会中的传输，第二变量用于随机接入信道在第二类型传输机会中的传输”，可以理解为第一变量用于随机接入信道在第一类型时域资源中的传输，第二变量用于随机接入信道在第二类型时域资源中的传输。第一类型时域资源为非SBFD符号，第二类型时域资源为SBFD符号。第二类型时域资源为包含上行子带和/或下行子带的时域资源类型。比如，第二类型时域资源为SBFD符号、SBFD时隙、SBFD子帧中的至少一种。
在一些实施例中，第一类型时域资源和第二类型时域资源可以理解为两种不同的双工方式、时隙或符号等。第一类型时域资源和第二类型时域资源中可用上行资源的数量、位置、大小、频域带宽是不同的；或者说第一类型时域资源和第二类型时域资源中随机接入信道的数量、位置、大小、频域带宽是不同的。例如第一类型时域资源为non-SBFD符号，第二类型时域资源为SBFD符号。其中，SBFD符号为包括上行子带、下行子带、保护带中至少之一的符号，non-SBFD符号为不包括以上子带的符号。
非SBFD符号关联的RO，可以理解为位于非SBFD符号内的RO、非SBFD符号中的RO等；SBFD符号同理，SBFD符号关联的RO，可以理解为位于SBFD符号内的RO、SBFD符号中的RO等；非SBFD时域资源关联的RO，可以理解为位于非SBFD时域资源内的RO、非SBFD时域资源中的RO等；SBFD时域资源同理，SBFD时域资源关联的RO，可以理解为位于SBFD时域资源内的RO、SBFD时域资源中的RO等。
1.第一类型传输机会。
第一类型传输机会包括如下至少之一：Non-SBFD符号中的RO；灵活符号中的RO；传统RO；第一随机接入信道配置中配置的RO。其中，灵活符号为没有确定传输方向的符号，可以根据控制信令的指示，规定灵活符号进行上行或者下行的传输；灵活符号可以是在上下行公共配置信令中被配置为灵活符号的符号。传统RO即为legacy RO，为在上述“在SBFD符号中的随机接入信道传输”中提到的legacy UE适用的RO，或者说传统RO为相关技术中的RO。第一随机接入信道配置用于配置小区特定(小区特定，可以理解为小区专有、小区专用等)的随机接入参数，即为在上述“在SBFD符号中的随机接入信道传输”中提到的legacy RACH configuration，也即当前协议中设定的rach-ConfigCommon。
2.第二类型传输机会。
第二类型传输机会包括如下至少之一：SBFD符号中的RO；在上下行公共配置信令中被配置为下行链路的SBFD符号中的RO；第二随机接入信道配置中配置的RO。其中，上下行公共配置信令中被配置为下行链路的SBFD符号即为SBFD symbols configured as downlink by tdd-UL-DL-ConfigurationCommon。第二随机接入信道配置第二随机接入信道配置为在第一随机接入信道配置之外的配置，即为在上述“在SBFD符号中的随机接入信道传输”中提到的Additional RACH configuration。
接下来介绍随机接入信道在第一类型传输机会或第二类型传输机会中传输时的变量。
3.第一变量与第二变量。
也即第一变量和/或第二变量包括如下变量中的至少之一：接收功率；功率等级；随机接入前导码的最大传输次数；随机接入信道的功率爬升步长；功率爬升计数器；随机接入前导码传输计数器。换句话说，第一变量包括如下变量中的至少之一：接收功率；功率等级；随机接入前导码的最大传输次数；随机接入信道的功率爬升步长；功率爬升计数器；随机接入前导码传输计数器。第二变量包括如下变量中的至少之 一：接收功率；功率等级；随机接入前导码的最大传输次数；随机接入信道的功率爬升步长；功率爬升计数器；随机接入前导码传输计数器。其中，接收功率用于指示终端设备会使用多少能量发送随机接入信道；功率等级用于指示网络设备的接收机所期望的随机接入信道的接收功率；功率爬升计数器用于指示功率爬升次数，一般来说，每次随机接入失败后，随机接入前导码传输计数器加1，在随机接入前导码传输计数器大于1时，若要传输随机接入信道，则功率爬升计数器会加1；随机接入前导码传输计数器用于指示随机接入过程中随机接入前导码(简称前导码)的传输次数，即随机接入信道的发送次数；随机接入前导码的最大传输次数用于指示整个随机接入过程中前导码的最大传输次数，也即随机接入信道的最大发送次数；随机接入信道的功率爬升步长用于指示每次功率爬升时的功率提升量。
在一些实施例中，第一变量与第二变量中的变量类型可以是相同的也可以是不同的；第一变量与第二变量中的同一类型变量的变量值可以是相同的也可以是不同的。本申请实施例对此不加以限定。例如，第一变量包括功率等级、随机接入前导码的最大传输次数、随机接入信道的功率爬升步长，第二变量包括功率等级、随机接入前导码的最大传输次数、随机接入信道的功率爬升步长和功率爬升计数器；或，第一变量和第二变量均包括功率等级、随机接入前导码的最大传输次数、随机接入信道的功率爬升步长。
作为举例而非限定，第一变量包括的功率等级为20dBm，第二变量包括的功率等级为-10dBm；或，第一变量和第二变量中的功率等级均为10dBm，第一变量包括的随机接入信道的功率爬升步长为2dB，第二变量包括的随机接入信道的功率爬升步长为4dB。
在随机接入过程中，对随机接入信道的传输结果的一个较大的影响因素为接收功率。若随机接入信道的接收功率过小，容易导致网络无法接收到该终端设备发送的随机接入信道，此时可以视为随机接入信道传输失败。在终端设备判定传输失败的情况下，将对随机接入信道的接收功率执行功率爬升，并基于爬升后的接收功率再次发送随机接入信道直至传输次数达到最大传输次数。而针对支持使用两种传输资源类型的终端设备而言，在随机接入过程中通常会分别使用两种传输资源类型来发送随机接入信道。
在一种可能的实现方式中，在每次随机接入信道传输时，终端设备任意选择第一类型传输机会和第二类型传输机会。
在另一种可能的实现方式中，终端设备使用其中一种类型的传输机会(第一类型传输机会或第二类型传输机会)达到一定次数后，可以切换到另外一种类型的传输机会进行传输。如，终端设备使用第一类型传输机会传输了n次随机接入信道后，切换为使用第二类型传输机会。第一类型传输机会与第二类型传输机会的传输次数是相同的或不同的。
无论是上述两种实现方式中的哪种实现方式，都需要考虑如何设计随机接入信道的接收功率的计算方式，也即设计随机接入信道的功率控制方式。
接收功率的计算方式一：累加；
接收功率的计算方式二：基于偏移值的功率爬升；
接收功率的计算方式三：和积。
对于接收功率而言，在本次传输失败可能会提高接收功率再次尝试随机接入信道的传输，而接收功率的提升(也可以称为功率爬升、接收功率的抬升等)主要涉及的两个变量是功率爬升计数器和功率爬升步长。因此在设计时也可以基于这两个变量进行设计。首先为第一类型传输机会和第二类型传输机会分别设置一个功率爬升步长，即，第一类型传输机会对应第一功率爬升步长，第二类型传输机会对应第二功率爬升步长；还可以理解为，第一变量包括第一功率爬升步长，第二变量包括第二功率爬升步长。使不同类型的传输机会对应不同的功率爬升步长，可以更有效的进行不同类型的传输机会上的干扰管理。如位于SBFD符号中的第二类型传输机会而言，在该传输机会上发送的随机接入信道可能会对下行传输(如使用SBFD符号中的下行子带的传输)产生干扰，因此针对第二类型传输机会的功率爬升步长可以设置的小一些来避免对同符号的下行传输的干扰。需要说明的是，针对本申请实施例提供的接收功率的计算方式而言，第一类型传输机会与第二类型传输机会对应相同的功率爬升步长的情况也是适用的，本申请实施例以第一类型传输机会与第二类型传输机会对应不同功率爬升步长的情况来举例说明，但本申请实施例的保护范围不限于此。
此时，随机接入信道的接收功率基于第一功率爬升步长和第二功率爬升步长中的至少之一确定，也即第一变量或第二变量包括的接收功率基于第一功率爬升步长和第二功率爬升步长中的至少之一确定。其中，若随机接入信道在第一类型传输机会中传输，则随机接入信道的接收功率为第一变量中的接收功率；若随机接入信道在第二类型传输机会中传输，则随机接入信道的接收功率为第二变量中的接收功率。
在基于第一变量包括第一功率爬升步长和第二变量包括第二功率爬升步长的基础上，存在两种设计思路，设计思路一是第一类型传输机会和第二类型传输机会对应相同的功率爬升计数器，设计思路二则是第一类型传输机会和第二类型传输机会分别对应一个功率爬升计数器。
接下来将结合设计思路一和设计思路二中对功率爬升步长和功率爬升计数器的设置，对上述三种接收 功率的计算方式做进一步介绍(介绍顺序不限制功率爬升方式的优劣)。
需要说明的是，随机接入信道对应第一类型传输机会，可以理解为随机接入信道对应第一类型时域资源；随机接入信道对应第二类型传输机会，可以理解为随机接入信道对应第二类型时域资源。
接收功率的计算方式一：累加。
累加的计算方式即本次传输的随机接入信道的接收功率是基于上一次传输的随机接入信道的接收功率和本次传输对应的功率爬升步长确定的。如，当第一变量和第二变量还包括相同的功率爬升计数器时，在第i+1次传输的随机接入信道对应第一类型传输机会的情况下，第i+1次传输的随机接入信道的接收功率基于第i次传输的接收功率和第一功率爬升步长确定，第i次传输的随机接入信道的接收功率基于第一功率爬升步长和第二功率爬升步长中的至少一个以及功率爬升计数器确定，i为正整数；在第i+1次传输的随机接入信道对应第二类型传输机会的情况下，第i+1次传输的随机接入信道的接收功率基于第i次传输的接收功率和第二功率爬升步长确定。也可以说，当第一变量和第二变量还包括相同的功率爬升计数器时，在第i+1次传输的随机接入信道对应第一类型传输机会的情况下，第i+1次传输的随机接入信道对应的接收功率基于第i次传输的接收功率和第一功率爬升步长确定，第i次传输的随机接入信道的接收功率基于第一功率爬升步长和第二功率爬升步长中的至少一个以及功率爬升计数器确定，i为正整数；在第i+1次传输的随机接入信道对应第二类型传输机会的情况下，第i+1次传输的随机接入信道对应的接收功率基于第i次传输的接收功率和第二功率爬升步长确定。其中，第一变量和第二变量包括相同的功率爬升计数器是指终端中仅存在一个功率爬升计数器，或者说随机接入过程中仅启用一个功率爬升计数器。
还可以表示为随机接入信道的接收功率基于第一累加和确定，第一累加和基于第一功率爬升步长和第二功率爬升步长中的至少一个以及功率爬升计数器确定。示例性的，第一累加和为第一数量个功率爬升步长的累加和，第一数量基于功率爬升计数器确定，第一数量个功率爬升步长中的每个功率爬升步长为第一功率爬升步长和第二功率爬升步长中的一个，如，第i个功率爬升步长为第一功率爬升步长或第二功率爬升步长，由第i次传输或重传的随机接入信道对应的传输机会类型确定(若第i次传输或重传的随机接入信道对应第一类型传输机会，第i个功率爬升步长为第一功率爬升步长；若第i次传输或重传的随机接入信道对应第二类型传输机会，第i个功率爬升步长为第二功率爬升步长)。例如，第一数量为4，则第一累加和为4个第一功率爬升步长和/或第二功率爬升步长的累加和，如1个第一功率爬升步长和3个第二功率爬升步长，0个第一功率爬升步长和4个第二功率爬升步长，2个第一功率爬升步长和2个第二功率爬升步长等。
其中，“在第i+1次传输的随机接入信道对应第一类型传输机会的情况下，第i+1次传输的随机接入信道的接收功率基于第i次传输的接收功率和第一功率爬升步长确定”等同于“在本次传输的随机接入信道对应第一类型传输机会的情况下，本次传输的随机接入信道的接收功率基于上一次传输的接收功率和第一功率爬升步长确定”；“在第i+1次传输的随机接入信道对应第二类型传输机会的情况下，第i+1次传输的随机接入信道的接收功率基于第i次传输的接收功率和第二功率爬升步长确定”等同于“在本次传输的随机接入信道对应第二类型传输机会的情况下，本次传输的随机接入信道的接收功率基于上一次传输的接收功率和第二功率爬升步长确定”。
示例性的，接收功率的计算公式如下所示。
式中，preambleReceivedTargetPower为功率等级，通常由RRC信令配置；DELTA_PREAMBLE表示前导码增量，基于随机接入前导码格式、使用的子载波间隔、协议约定的固定值中的至少之一确定；i表示重传次数，preamble_power_ranmping_counter表示功率爬升计数器，PREAMBLE_POWER_RAMPI NG_STEP_i表示第i次重传对应的功率爬升步长，该值是基于第i次重传所使用的随机接入信道确定的，也即，若第i次重传的随机接入信道为第一类型传输机会，则PREAMBLE_POWER_RAMPING_STEP_i＝PREAMBLE_POWER_RAMPING_STEP_1，PREAMBLE_POWER_RAMPING_STEP_1为第一功率爬升步长；若第i重传的随机接入信道为第二类型传输机会，则PREAMBLE_POWER_RAMPING_STEP_i＝PRE AMBLE_POWER_RAMPING_STEP_2，PREAMBLE_POWER_RAMPING_STEP_2为第二功率爬升步长。
示例性的，上述“第一数量基于功率爬升计数器确定”，可以表示为第一数量为功率爬升计数器减1。
作为举例而非限定，第一功率爬升步长为2，第二功率爬升步长为1，在使用该接收功率的计算公式进行计算时，第1次传输(即初传)开始前，功率爬升计数器初始化为1，即第1次传输时第1次传输时无论是随机接入信道使用第一类型传输机会还是第二类型传输机会，计算得到的接收功率都是相等的；在第1次传输失败后，开始第2次传输，此时功率爬升计数器加1，功率爬升计数器为2；在第2次传输的随机接入信道 对应第一类型传输机会的情况下，第2次传输时在第2次传输失败后，开始第3次传输，此时功率爬升计数器加1，功率爬升计数器为3；在第3次传输的随机接入信道对应第二类型传输机会的情况下，第3次传输时 ……；直至随机接入成功或终端设备判定随机接入失败。其中，第2次传输可以称为第1次重传，第3次传输可以称为第2次重传，……，第i次传输可以称为第i-1次重传，第i+1次传输可以称为第i次重传。
从公式中可以看出，累加的计算方式是指在上一次传输的接收功率的基础上在加上本次传输的接收功率需要提升的功率爬升步长。
需要说明的是，上式中的可以写作
也即，从第2次传输(第1次重传)开始，
式中，j表示传输次数，PREAMBLE_POWER_RAMPING_STEP_j表示第j次传输对应的功率爬升步长，该值是基于第j次传输所使用的随机接入信道确定的，也即，若第j次传输的随机接入信道为第一类型传输机会，则PREAMBLE_POWER_RAMPING_STEP_j＝PREAMBLE_POWER_RAMPING_STEP_1，PREAMBLE_POWER_RAMPING_STEP_1为第一功率爬升步长；若第j次传输的随机接入信道为第二类型传输机会，则PREAMBLE_POWER_RAMPING_STEP_j＝PREAMBLE_POWER_RAMPING_STEP_2，PREAMBLE_POWER_RAMPING_STEP_2为第二功率爬升步长。
另一方面，第一变量与第二变量中除了功率爬升步长和接收功率不同外，还可以设置功率等级、随机接入前导码的最大传输次数、随机接入前导码传输计数器是相同的或不同的。
例如，第一变量还包括第一功率等级，第二变量还包括第二功率等级。此时随机接入信道使用第一类型传输机会的第一接收功率与随机接入信道使用第二类型传输机会的第二接收功率的计算公式如下所示。

式中，preambleReceivedTargetPower_1表示第一功率等级，preambleReceivedTargetPower_2表示第二功率等级。可选地，第二功率等级小于第一功率等级。
需要说明的是，上述列出的接收功率的计算公式中仅涉及功率等级、前导码增量、功率爬升步长和功率爬升计数器这四个变量，但在实际使用过程中，接收功率的计算公式中还可以根据实际需求添加其他变量。如在涉及随机接入过程的回退机制的情况下，接收功率的计算公式中还可以添加功率偏差(POWER_OFFSET_2STEP_RA)这一变量，POWER_OFFSET_2STEP_RA为继承MsgA前导的功率提升量(也可以称为功率抬升量)时存在的功率偏差，初始化为0dB。MsgA是两步随机接入中终端设备用于发送随机接入信道的过程，与四步随机接入中的Msg1类似。
例如，以接收功率的计算方式一所示出的计算公式为例，该公式也可以如下式所示。
综上所述，本申请实施例提供的方法，采用累加的方式计算接收功率提供了一种新的接收功率的计算方式。此外，针对第一变量和第二变量分别设置功率爬升步长，可以实现不同的RO的类型对应不同的功率爬升步长，这样可以更有效的进行不同类型的传输机会上的干扰管理，例如SBFD符号中的RO上传输的随机接入信道可能对下行传输产生干扰，因此功率爬升步长可以设置的小一些，来避免对同符号的下行传输的干扰。并且该方式的终端设备只需要维持一个功率爬升计数器，对终端设备而言实现比较简单。
接收功率的计算方式二：基于偏移值的计算。
基于偏移值的计算方式即在相关技术示出的计算公式的基础上为接收功率添加偏移值。偏移值表示第一类型传输机会的功率爬升相对于第二类型传输机会的功率爬升的偏移；或，偏移值表示第二类型传输机 会的功率爬升相对于第一类型传输机会的功率爬升的偏移；或，偏移值表示本次传输前第一类型传输机会的功率爬升相对于第二类型传输机会的功率爬升的偏移；或，偏移值表示本次传输前第二类型传输机会的功率爬升相对于第一类型传输机会的功率爬升的偏移；或，在第i次传输时的偏移值表示在前i-1次传输中第二类型传输机会的总功率爬升相对于第一类型传输机会的总功率爬升的偏移；或，在第i次传输时的偏移值表示在前i-1次传输中第一类型传输机会的总功率爬升相对于第二类型传输机会的总功率爬升的偏移。其中，i为大于2的正整数，总功率爬升为每次传输相对于上一次传输的功率爬升的和。
基于偏移值的计算方式对于上述设计思路一和设计思路二均适用。因此接下来将分别对采用设计思路一的基于偏移值的计算方式和采用设计思路二的基于偏移值的计算方式进行介绍。
1.采用设计思路一：第一类型传输机会和第二类型传输机会对应相同的功率爬升计数器。
在一些实施例中，第一变量和第二变量还包括相同的功率爬升计数器；随机接入信道的接收功率基于功率爬升计数器、第一功率爬升步长和第一偏移值确定，第一偏移值表示第二类型传输机会的功率爬升相对于第一类型传输机会的功率爬升的偏移值；或，随机接入信道的接收功率基于功率爬升计数器、第二功率爬升步长和第二偏移值确定，第二偏移值表示第一类型传输机会的功率爬升相对于第二类型传输机会的功率爬升的偏移值。其中，第一变量和第二变量包括相同的功率爬升计数器是指终端中仅存在一个功率爬升计数器，或者说，随机接入过程仅启用一个功率爬升计数器。
在一些实施例中，随机接入信道的接收功率基于第一乘积和第一偏移值确定，第一乘积基于功率爬升计数器和第一功率爬升步长确定；或，随机接入信道的接收功率基于第二乘积和第二偏移值确定，第二乘积基于功率爬升计数器和第二功率爬升步长确定。示例性的，第一乘积为功率爬升计数器与1的差值乘第一功率爬升步长；第二乘积为功率爬升计数器与1的差值乘第二功率爬升步长。
示例性的，随机接入信道的接收功率的计算公式如下所示。
接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_1+POWER_OFFSET_2；
或，接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_2+POWER_OFFSET_1。
式中，PREAMBLE_POWER_RAMPING_COUNTER为功率爬升计数器；PREAMBLE_POWER_RAMPING_STEP_1为第一功率爬升步长；PREAMBLE_POWER_RAMPING_STEP_2为第二功率爬升步长；POWER_OFFSET_2为第一偏移值；POWER_OFFSET_1为第二偏移值。
其中，第一偏移值的计算公式为POWER_OFFSET_2＝(PREAMBLE_POWER_RAMPING_COUNTER–1)×(PREAMBLE_POWER_RAMPING_STEP_2–PREAMBLE_POWER_RAMPING_STEP_1)。
第二偏移值的计算公式为POWER_OFFSET_1＝(PREAMBLE_POWER_RAMPING_COUNTER–1)×(PREAMBLE_POWER_RAMPING_STEP_1–PREAMBLE_POWER_RAMPING_STEP_2)。
也即，第一偏移值基于功率爬升计数器、第一功率爬升步长和第二功率爬升步长确定；第二偏移值基于功率爬升计数器、第一功率爬升步长和第二功率爬升步长确定。
示例性的，第一偏移值基于第一差值与第二差值的乘积确定，第一差值为功率爬升计数器减1，第二差值为第二功率爬升步长与第一功率爬升步长的差；第二偏移值基于第三差值用于第四差值的乘积确定，第三差值为功率爬升计数器减1，第四差值为第一功率爬升步长与第二功率爬升步长的差。
换句话说，随机接入信道的接收功率基于功率爬升计数器、第一功率爬升步长和第二功率爬升步长确定。
另一方面，第一变量与第二变量中除了功率爬升步长和接收功率不同外，还可以设置功率等级、随机接入前导码的最大传输次数、随机接入前导码传输计数器是相同的或不同的。
需要说明的是，上述列出的接收功率的计算公式中仅涉及功率等级、前导码增量、功率爬升步长和功率爬升计数器这四个变量，但在实际使用过程中，接收功率的计算公式中还可以根据实际需求添加其他变量。如在涉及随机接入过程的回退机制的情况下，接收功率的计算公式中还可以添加功率偏差(POWER_OFFSET_2STEP_RA)这一变量，POWER_OFFSET_2STEP_RA为继承MsgA前导的功率提升量(也可以称为功率抬升量)时存在的功率偏差，初始化为0dB。MsgA是两步随机接入中终端设备用于发送随机接入信道的过程，与四步随机接入中的Msg1类似。
对于第一偏移值和/或第二偏移值的计算时机、随机接入信道的接收功率的计算公式的运用，可以根据使用不同类型的传输机会造成的信道干扰、对随机接入过程的时延要求等灵活设置。
例如，在初传选择第一类型传输机会传输的情况下，第一类型传输机会采用接收功率的传统计算公式，第二类型传输机会采用上述计算公式。
即，第一接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_1；
第二接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_2+POWER_OFFSET_1。
式中，PREAMBLE_POWER_RAMPING_STEP_1表示第一功率爬升步长，PREAMBLE_POWER_RAMPING_STEP_2表示第二功率爬升步长，POWER_OFFSET_1表示第二偏移值。
此时，在随机接入信道对应第二类型传输机会的情况下，随机接入信道的接收功率基于第二乘积和第二偏移值确定，第二乘积基于功率爬升计数器和第二功率爬升步长确定。
或，在初传选择第二类型传输机会传输的情况下，第二类型传输机会采用接收功率的传统计算公式，第一类型传输机会采用上述计算公式。
即，第一接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_1+POWER_OFFSET_2；
第二接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_2。
式中，PREAMBLE_POWER_RAMPING_STEP_1表示第一功率爬升步长，PREAMBLE_POWER_RAMPING_STEP_2表示第二功率爬升步长，POWER_OFFSET_2表示第一偏移值。
此时，在随机接入信道对应第一类型传输机会的情况下，随机接入信道的接收功率基于第一乘积和第一偏移值确定，第一乘积基于功率爬升计数器和第一功率爬升步长确定。
其中，针对包括第一偏移值和第二偏移值在内的偏移值的计算，是在传输机会类型发生切换前计算的，即每发生一次RO的类型的改变，就重新计算一次偏移值，该偏移值将一直使用到下一次发生RO的类型的改变。
接下来，以第一类型传输机会采用接收功率的传统计算公式，第二类型传输机会采用上述计算公式进行说明。假设第一功率爬升步长为2，第二功率爬升步长为1，接收功率中的其他部分preambleReceivedTargetPower+DELTA_PREAMBLE为x；则在第1次传输时，由于使用的是第一类型传输机会，因此使用传统计算公式，最终计算得到的第1次传输的接收功率为x，接收功率的计算参数和结果如表1所示；在第2次传输时，仍使用的是第一类型传输机会，最终计算得到的第2次传输的接收功率为x+2；在第3次传输时，使用的RO的类型发生了改变，额外计算第二偏移值(即，第一类型传输机会的功率爬升相对于第二类型传输机会的功率爬升的偏移)，此时计算得到的第二偏移值是1，在接收功率计算时，接收功率得到第3次传输的接收功率是x+3；在第4次传输时，仍使用第二类型传输机会，第二偏移值是1，接收功率是x+4；在第5次传输时，仍使用第二类型传输机会，第二偏移值是1，接收功率是x+5。
表1.接收功率的计算结果
需要说明的是，在RO的类型发生切换时，本申请实施例以功率爬升计数器继续加1来举例说明，但在实际实现中，当RO的类型发生切换时，功率爬升计数器还可以是不变或重置，以使得能更好的匹配不同类型的RO的干扰情况。
示例性的，当RO的类型发生切换时，功率爬升计数器不变的情况如表2所示，在第3次传输时，从第一类型传输机会切换到第二类型传输机会上，功率爬升计数器仍为第2次传输时的2。
表2.接收功率的计算结果
示例性的，当RO的类型发生切换时，功率爬升计数器重置的情况如表3所示，在第3次传输时，从第一类型传输机会切换到第二类型传输机会上，功率爬升计数器重置为1。
表3.接收功率的计算结果

综上所述，本申请实施例提供的方法，采用偏移值的方式计算接收功率提供了一种新的接收功率的计算方式。此外，针对第一变量和第二变量分别设置功率爬升步长，可以实现不同的RO的类型对应不同的功率爬升步长，这样可以更有效的进行不同类型的传输机会上的干扰管理，例如SBFD符号中的RO上传输的随机接入信道可能对下行传输产生干扰，因此功率爬升步长可以设置的小一些，来避免对同符号的下行传输的干扰。并且该方式的终端设备只需要维持一个功率爬升计数器，对终端设备而言实现比较简单。
2.采用设计思路二：第一类型传输机会和第二类型传输机会对应不同功率爬升计数器。
在一些实施例中，第一变量和第二变量还包括第三功率爬升计数器，第一变量或第二变量还包括第四功率爬升计数器；也即，第三功率爬升计数器用于记录随机接入信道在第一类型传输机会和第二类型传输机会中传输时功率爬升的总次数，第四功率爬升计数器用于记录随机接入信道在第一类型传输机会或第二类型传输机会中传输时功率爬升的次数。例如，第三功率爬升计数器用于记录随机接入信道在第一类型传输机会和第二类型传输机会中传输时功率爬升的总次数，第一变量和第二变量包括第三功率爬升计数器。第四功率爬升计数器用于记录随机计入信道在第二类型传输机会中传输时功率爬升的次数，第二变量还包括第四功率爬升计数器；或，第四功率爬升计数器用于记录随机计入信道在第一类型传输机会中传输时功率爬升的次数，第一变量还包括第四功率爬升计数器。
此时，随机接入信道的接收功率基于第三功率爬升计数器、第一功率爬升步长、第三偏移值确定，第三偏移值表示第二类型传输机会的功率爬升相对于第一类型传输机会的功率爬升的偏移值；或，随机接入信道的接收功率基于第三功率爬升计数器、第二功率爬升步长、第四偏移值确定，第四偏移值表示第一类型传输机会的功率爬升相对于第一类型传输机会的功率爬升的偏移值。
在一些实施例中，随机接入信道的接收功率基于第三乘积和第三偏移值确定，第三乘积基于第三功率爬升计数器和第一功率爬升步长确定；或，随机接入信道的接收功率基于第四乘积和第四偏移值确定，第四乘积基于第三功率爬升计数器和第二功率爬升步长确定。示例性的，第三乘积为第三功率爬升计数器与1的差值乘第一功率爬升步长；第四乘积为第三功率爬升计数器与1的差值乘第二功率爬升步长。
示例性的，随机接入信道的接收功率的计算公式如下所示。
接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_1+POWER_OFFSET_2；
或，接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_2+POWER_OFFSET_1。
式中，PREAMBLE_POWER_RAMPING_COUNTER为第三功率爬升计数器；PREAMBLE_POWER_RAMPING_STEP_1为第一功率爬升步长；PREAMBLE_POWER_RAMPING_STEP_2为第二功率爬升步长；POWER_OFFSET_2为第三偏移值；POWER_OFFSET_1为第四偏移值。
其中，第三偏移值的计算公式为POWER_OFFSET_2＝(PREAMBLE_POWER_RAMPING_COUNTER_2–1)×(PREAMBLE_POWER_RAMPING_STEP_2-PREAMBLE_POWER_RAMPING_STEP_1)。
第四偏移值的计算公式为POWER_OFFSET_1＝(PREAMBLE_POWER_RAMPING_COUNTER_2–1)×(PREAMBLE_POWER_RAMPING_STEP_1-PREAMBLE_POWER_RAMPING_STEP_2)。
式中，PREAMBLE_POWER_RAMPING_COUNTER_2为第四功率爬升计数器。
也即，第三偏移值基于第四功率爬升计数器、第一功率爬升步长和第二功率爬升步长确定；第二偏移值基于第四功率爬升计数器、第一功率爬升步长和第二功率爬升步长确定。
示例性的，第三偏移值基于第五差值与第六差值的乘积确定，第五差值为第四功率爬升计数器减1，第六差值为第二功率爬升步长与第一功率爬升步长的差；第四偏移值基于第七差值用于第八差值的乘积确定，第七差值为第四功率爬升计数器减1，第八差值为第一功率爬升步长与第二功率爬升步长的差。
换句话说，随机接入信道的接收功率基于第三功率爬升计数器、第四功率爬升计数器、第一功率爬升步长、第二功率爬升步长确定。
对于第三偏移值和/或第四偏移值的计算时机、随机接入信道的接收功率的计算公式的运用，可以根据使用不同类型的传输机会造成的信道干扰、对随机接入过程的时延要求等灵活设置。
在一些实施例中，第一接收功率和/或第二接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_1+POWER_OFFSET_2。或，第一接收功率和/或第二接收功率＝preambleReceivedTargetPower+DELTA_PREAMB LE+(PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP_2+POWER_OFFSET_1。
在一些实施例中，第一变量和第二变量还包括相同或不同的随机接入前导码传输计数器；在随机接入前导码传输计数器的取值大于1的情况下，第三功率爬升计数器的取值加1；在随机接入前导码传输计数器的取值大于1，且随机接入信道传输对应为第四功率爬升计数器对应的传输机会的情况下，第四功率爬升计数器的取值加1，传输机会包括第一类型传输机会和第二类型传输机会。也可以说，在第一变量和第二变量包括的随机接入前导码传输计数器的取值大于1的情况下，第三功率爬升计数器的取值加1。第一变量包括第四功率爬升计数器，在第一变量包括的随机接入前导码传输计数器的取值大于1，且随机接入信道传输对应为第一类型传输机会的情况下，第四功率爬升计数器的取值加1；或，第二变量包括第四功率爬升计数器，在第二变量包括的随机接入前导码传输计数器的取值大于1，且随机接入信道传输对应为第二类型传输机会的情况下，第四功率爬升计数器的取值加1。也即，当第i-1次传输失败，随机接入前导码传输计数器的取值加1，在第i次传输时，若随机接入前导码传输计时器的取值大于1，第三功率爬升计数器的取值加1；若随机接入前导码传输计数器的取值大于1，且第i次传输时，随机接入信道对应为第四功率爬升计数器对应的传输机会的情况下，第四功率爬升计数器的取值加1，i为正整数。
在一些实施例中，偏移值的计算是在每次传输是执行的，也即，每次计算接收功率时，均会更新偏移值。
接下来以第一功率爬升步长为2，第二功率爬升步长为1，接收功率中的其他部分preambleReceivedTargetPower+DELTA_PREAMBLE为x，第三偏移值的初始值为0，第四功率爬升计数器用于记录随机接入信道在第二类型传输机会中传输时功率爬升的次数，在每次传输时计算偏移值进行举例说明。在第1次传输时，由于使用的是第一类型传输机会，最终计算得到的第1次传输的接收功率为x，接收功率的计算参数和结果如表4所示；在第2次传输时，仍使用的是第一类型传输机会，第三功率爬升计数器加1，第四功率爬升计数器不变仍为初始值1，计算得到的第三偏移值仍为0，最终计算得到的第2次传输的接收功率为x+2；在第3次传输时，使用的RO的类型发生了改变，第三功率爬升计数器加1，第四功率爬升计数器也加1，此时计算得到的第三偏移值是-1，再计算接收功率得到第3次传输的接收功率是x+3；在第4次传输时，第三功率爬升计数器加1，第四功率爬升计数器也加1，计算得到的第三偏移值是-2，最终计算得到的接收功率是x+4；在第5次传输时，仍使用第二类型传输机会，第三功率爬升计数器加1，第四功率爬升计数器也加1，计算得到的第三偏移值是-3，最终计算得到的接收功率是x+5。
表4.接收功率的计算结果
需要说明的是，在RO的类型发生切换时，本申请实施例以功率爬升计数器继续加1来举例说明，但在实际实现中，当RO的类型发生切换时，功率爬升计数器还可以是不变或重置，以使得能更好的匹配不同类型的RO的干扰情况。
综上所述，本申请实施例提供的方法，采用偏移值的方式计算接收功率提供了一种新的接收功率的计算方式。此外，针对第一变量和第二变量分别设置功率爬升步长，可以实现不同的RO的类型对应不同的功率爬升步长，这样可以更有效的进行不同类型的传输机会上的干扰管理，例如SBFD符号中的RO上传输的随机接入信道可能对下行传输产生干扰，因此功率爬升步长可以设置的小一些，来避免对同符号的下行传输的干扰。并且该方式使用两个功率爬升技术器来实现，一个和传统计数器一样，不区分RO类型，另外一个计数器对应其中一种类型的RO，这样的话可以最小化协议的改动，标准影响小，但是终端实现复杂。
接收功率的计算方式三：和积。
在一些实施例中，第一变量还包括第一功率爬升计数器，第二变量还包括第二功率爬升计数器，也即， 第一功率爬升计数器用于记录随机接入信道在第一类型传输机会中传输时功率爬升的次数，第二功率爬升计数器用于记录随机接入信道在第二类型传输机会中传输时功率爬升的次数。和积的计算方式即本次传输的接收功率是基于第一功率爬升步长、第一功率爬升计数器、第二功率爬升步长、第二功率爬升计数器确定，即随机接入信道的接收功率基于第一功率爬升步长、第一功率爬升计数器、第二功率爬升步长、第二功率爬升计数器确定。
示例性的，接收功率的计算公式如下所示。
接收功率＝preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER_1–1)×PREAMBLE_POWER_RAMPING_STEP_1+(PREAMBLE_POWER_RAMPING_COUNTER_2–1)×PREAMBLE_POWER_RAMPING_STEP_2。
式中，PREAMBLE_POWER_RAMPING_COUNTER_1表示第一功率爬升计数器，PREAMBLE_POWER_RAMPING_COUNTER_2表示第二功率爬升计数器，PREAMBLE_POWER_RAMPING_STEP_1表示第一功率爬升步长，PREAMBLE_POWER_RAMPING_STEP_2表示第二功率爬升步长。
在一些实施例中，第一变量和第二变量还包括相同或不同的随机接入前导码传输计数器；在随机接入前导码传输计数器的取值大于1，且随机接入信道传输对应为第一类型传输机会的情况下，第一功率爬升计数器的取值加1；在随机接入前导码传输计数器的取值大于1，且随机接入信道传输对应为第二类型传输机会的情况下，第二功率爬升计数器的取值加1。也可以说，在第一变量包括的随机接入前导码传输计数器的取值大于1，且随机接入信道传输对应为第一类型传输机会的情况下，第一功率爬升计数器的取值加1；在第二变量包括的随机接入前导码传输计数器的取值大于1，且随机接入信道传输对应为第二类型传输机会的情况下，第二功率爬升计数器的取值加1。
也即，当第i-1次传输失败，随机接入前导码传输计数器的取值加1。在第i次传输时，若随机接入前导码传输计时器的取值大于1，且随机接入信道传输对应为第一类型传输机会，第一功率爬升计数器的取值加1；或，在第i次传输时，若随机接入前导码传输计数器的取值大于1，且随机接入信道传输对应为第二类型传输机会，第二功率爬升计数器的取值加1，i为正整数。
接下来以第一功率爬升步长为2，第二功率爬升步长为1，接收功率中的其他部分preambleReceivedTargetPower+DELTA_PREAMBLE为x，(PREAMBLE_POWER_RAMPING_COUNTER_1–1)×PREAMBLE_POWER_RAMPING_STEP_1为第一中间式，(PREAMBLE_POWER_RAMPING_COUNTER_2–1)×PREAMBLE_POWER_RAMPING_STEP_2为第二中间式进行举例说明。在第1次传输时，第一功率爬升计数器和第二功率爬升计数器初始化为1，最终计算得到的第1次传输的接收功率为x，接收功率的计算参数和结果如表5所示；在第2次传输时，仍使用的是第一类型传输机会，第一功率爬升计数器加1，第二功率爬升计数器不变仍为初始值1，最终计算得到的第2次传输的接收功率为x+2；在第3次传输时，使用的RO的类型发生了改变，第一功率爬升计数器不变仍为2，第二功率爬升计数器加1，计算接收功率得到第3次传输的接收功率是x+3；在第4次传输时，第一功率爬升计数器不变仍为2，第二功率爬升计数器也加1，计算得到的接收功率是x+4；在第5次传输时，仍使用第二类型传输机会，第一功率爬升计数器不变仍为2，第二功率爬升计数器再加1，计算得到的接收功率是x+5。
表5.接收功率的计算结果
另一方面，第一变量与第二变量中除了功率爬升步长和接收功率不同外，还可以设置功率等级、随机接入前导码的最大传输次数、随机接入前导码传输计数器是相同的或不同的。
需要说明的是，上述列出的接收功率的计算公式中仅涉及功率等级、前导码增量、功率爬升步长和功率爬升计数器这四个变量，但在实际使用过程中，接收功率的计算公式中还可以根据实际需求添加其他变量。如在涉及随机接入过程的回退机制的情况下，接收功率的计算公式中还可以添加功率偏差(POWER_ OFFSET_2STEP_RA)这一变量，POWER_OFFSET_2STEP_RA为继承MsgA前导的功率提升量(也可以称为功率抬升量)时存在的功率偏差，初始化为0dB。MsgA是两步随机接入中终端设备用于发送随机接入信道的过程，与四步随机接入中的Msg1类似。
综上所述，本申请实施例提供的方法，采用和积的方式计算接收功率提供了一种新的接收功率的计算方式。此外，针对第一变量和第二变量分别设置功率爬升步长，可以实现不同的RO的类型对应不同的功率爬升步长，这样可以更有效的进行不同类型的传输机会上的干扰管理，例如SBFD符号中的RO上传输的随机接入信道可能对下行传输产生干扰，因此功率爬升步长可以设置的小一些，来避免对同符号的下行传输的干扰。并且该方式使用两个功率爬升技术器来实现，分别对应两种类型的RO，协议设计简单，但是终端实复杂。
针对终端设备选择第一类型传输机会或第二类型传输机会来传输随机接入信道的两种实现方式，尤其是第二种使用其中一种类型的传输机会(第一类型传输机会或第二类型传输机会)达到一定次数后，可以切换到另外一种类型的传输机会进行传输的实现方式，需要为终端设备设置相关变量以支持终端设备判断何时改变所使用的RO的类型。
随机接入信道使用的传输机会类型，基于随机接入前导码的最大传输次数和随机接入前导码传输计数器确定。随机接入信道传输机会类型包括第一类型和第二类型，第一类型的随机接入信道传输机会为第一类型传输机会，第二类型的随机接入信道传输机会为第二类型传输机会。

其中，随机接入信道传输机会类型也可以称为传输机会类型、RO类型、RO的类型等或其他等同称呼，本申请实施例对此不加以限定。
此外，第一最大传输次数用于指示随机接入信道的最大传输次数，等同于第一最大传输次数用于指示宣布随机接入失败前执行的随机接入前导码传输的最大次数，还可以说第一最大传输次数用于指示宣布随机接入失败前执行的随机接入信道传输的最大次数。
在一些实施例中，第二变量包括第二最大传输次数，在随机接入前导码传输计数器的取值小于第二最大传输次数加1，且随机接入前导码传输计数器的取值小于第一最大传输次数加1的情况下，在第二类型传输机会中发送随机接入信道；在随机接入前导码传输计数器的取值大于或等于第二最大传输次数加1，且随机接入前导码传输计数器的取值小于第一最大传输次数加1的情况下，在第一类型传输机会中发送随机接入信道；在随机接入前导码传输计数器的取值等于第一最大传输次数加1的情况下，上报随机接入问题，随机接入问题用于指示终端设备的随机接入过程存在异常。
在一些实施例中，第一变量包括第二最大传输次数，在随机接入前导码传输计数器的取值小于第二最大传输次数加1，且随机接入前导码传输计数器的取值小于第一最大传输次数加1的情况下，在第一类型传输机会中发送随机接入信道；在随机接入前导码传输计数器的取值大于或等于第二最大传输次数加1，且随机接入前导码传输计数器的取值小于第一最大传输次数加1的情况下，在第二类型传输机会中发送随机接入信道；在随机接入前导码传输计数器的取值等于第一最大传输次数加1的情况下，上报随机接入问题，随机接入问题用于指示终端设备的随机接入过程存在异常。
在第i次传输的随机接入信道对应第一类型传输机会的情况下，随机接入前导码传输计数器的取值加1；在第i次传输的随机接入信道对应第二类型传输机会的情况下，随机接入前导码传输计数器的取值加1。
综上所述，本申请实施例提供的方法，可以实现随机接入信道的初传和重传在两种RO之间的切换，但是该方式是有条件的切换，例如一种RO使用达到一定次数后，切换到另一种RO。
判断方式二：两个随机接入前导码传输计数器。

在一些实施例中，第一变量包括第三最大传输次数和第一随机接入前导码传输计数器，第二变量包括第四最大传输次数和第二随机接入前导码传输计数器，第三最大传输次数用于指示随机接入信道在第一类型传输机会上传输的最大传输次数，第四最大传输次数用于指示随机接入信道在第二类型传输机会上传输的最大传输次数；传输机会类型基于第三最大传输次数、第四最大传输次数、第一随机接入前导码传输计 数器和第二随机接入前导码传输计数器中的至少之一确定。
在一些实施例中，在随机接入信道的第i次传输失败，且第i次传输的随机接入信道对应第一类型传输机会的情况下，第一随机接入前导码传输计数器的取值加1；在随机接入信道的第i次传输失败，第i次传输的随机接入信道对应第二类型传输机会的情况下，第二随机接入前导码传输计数器的取值加1。
在第一随机接入前导码传输计数器的取值大于或等于第三最大传输次数加1，且第二随机接入前导码传输计数器的取值小于第四最大传输次数加1的情况下，第i+1次传输仅使用第二类型传输机会；在第二随机接入前导码传输计数器的取值大于或等于第四最大传输次数加1，且第一随机接入前导码传输计数器的取值小于第三最大传输次数加1的情况下，第i+1次传输仅使用第一类型传输机会。
在第一随机接入前导码传输计数器的取值等于第三最大传输次数加1，且第二随机接入前导码传输计数器的取值等于第四最大传输次数加1的情况下，上报随机接入问题，随机接入问题用于指示终端设备的随机接入过程存在异常。i为正整数。

需要说明的是，该方式在实际传输过程中，是可以自由选择使用的传输机会类型的，除非一种传输机会类型对应的前导码传输计数器已等于该传输机会类型对应的最大传输次数，且另一种传输机会类型对应的前导码传输计数器小于该传输机会类型对应的最大传输次数，则后续的传输中仅能使用另一种传输机会类型。
2.一个随机接入前导码传输计数器对应第一类型传输机会和第二类型传输机会，另一个随机接入前导码传输计数器对应第一类型传输机会或第二类型传输机会

需要说明的是，该方式在实际传输过程中，是可以自由选择使用的传输机会类型的，除非一种传输机会类型对应的前导码传输计数器已等于该传输机会类型对应的最大传输次数，且另一种传输机会类型对应的前导码传输计数器小于该传输机会类型对应的最大传输次数，则后续的传输中仅能使用另一种传输机会类型。
综上所述，本申请实施例提供的方法可以实现PRACH初传和重传在两种RO之间的自由切换，且不需要切换条件。1中示出的方法可以单独控制使用第一类型RO和第二类型RO进行PRACH传输的最大次数，比较灵活，但是逻辑复杂。而2中示出的方法可以单独控制第一类型RO或第二类型RO进行PRACH传输的最大次数，其他复用现有技术，标准影响小一些，灵活度较1示出的方法差一些。

最后示出随机接入信道的配置方法。
在基于图4的可选实施例中，如图6所示，该方法还包括：
步骤410：确定第一配置和/或第二配置，第一配置和/或第二配置用于配置随机接入信道的第一变量和/或第二变量。

综上所述，本申请实施例提供的方法，网络设备确定随机接入信道的第一配置和第二配置进行随机接入，由于第一配置对应第一类型传输机会(和第二类型传输机会)，第二配置对应第二类型传输机会(和第一类型传输机会)；这使终端设备能够在随机接入过程中针对不同类型的RO选择不同的配置。
图8示出了本申请一个示例性实施例提供的随机接入信道的传输装置的结构框图，该装置可以通过软件或硬件或两者的结合实现成为终端设备，或实现成为终端设备的一部分，该装置包括：
发送模块610，用于基于第一变量和第二变量中的至少一种，发送随机接入信道。
其中，第一变量用于随机接入信道在第一类型传输机会中的传输，第二变量用于随机接入信道在第二类型传输机会中的传输。也即，随机接入信道在第一类型传输机会中传输时采用的变量为第一变量；随机接入信道在第二类型传输机会中传输时采用的变量为第二变量。
第一类型传输机会和第二类型传输机会可以理解为采用两种不同的双工方式的传输机会。
在一些实施例中，终端设备根据第一变量和第二变量中的至少一种，选择第一类型传输机会或第二类型传输机会发送随机接入信道；或，终端设备选择第一类型传输机会或第二类型传输机会，再根据第一类型传输机会对应的第一变量或第二类型传输机会对应的第二变量，发送随机接入信道。例如，终端设备根据第一变量和第二变量中的第一部分变量，确定选择第一类型传输机会发送随机接入信道，随机接入信道在传输过程中的变量由第一变量中的第二部分变量确定。或，终端设备选择了第一类型传输机会，根据第一变量来发送随机接入信道；或，终端选择了第二类型传输机会，根据第二变量来发送随机接入信道。
综上所述，本申请实施例提供的装置，为第一类型传输机会和第二类型传输机会设置不同的变量，在随机接入信道的发送过程中基于第一类型传输机会对应的第一变量和第二类型传输机会对应的第二变量来确定随机接入信道传输过程中的变量，也即实现了终端设备针对不同类型的随机接入信道传输机会能够确定每种类型的随机接入信道传输机会下用于传输的变量，并根据该变量发送随机接入信道。
图9示出了本申请一个示例性实施例提供的随机接入信道的传输装置的结构框图，该装置可以通过软件或硬件或两者的结合实现成为网络设备，或实现成为网络设备的一部分，该装置包括：
接收模块710，用于接收随机接入信道，随机接入信道基于第一变量和第二变量中的至少一种传输。
其中，第一变量用于随机接入信道在第一类型传输机会中的传输，第二变量用于随机接入信道在第二类型传输机会中的传输时。也即，随机接入信道在第一类型传输机会中传输时采用的变量为第一变量；随机接入信道在第二类型传输机会中传输时采用的变量为第二变量。
第一类型传输机会和第二类型传输机会可以理解为采用两种不同的双工方式的传输机会。
在一些实施例中，随机接入信道是终端根据第一变量和第二变量中的至少一种，选择第一类型传输机会或第二类型传输机会发送的；或，随机接入信道是终端设备选择第一类型传输机会或第二类型传输机会，再根据第一类型传输机会对应的第一变量或第二类型传输机会对应的第二变量发送的。例如，终端设备根据第一变量和第二变量中的第一部分变量，确定选择第一类型传输机会发送随机接入信道，随机接入信道在传输过程中的变量由第一变量中的第二部分变量确定。或，终端设备选择了第一类型传输机会，根据第一变量来发送随机接入信道；或，终端选择了第二类型传输机会，根据第二变量来发送随机接入信道。
综上所述，本申请实施例提供的装置接收到的随机接入信道是终端设备通过为第一类型传输机会和第 二类型传输机会设置不同的变量，在随机接入信道的发送过程中基于第一类型传输机会对应的第一变量和第二类型传输机会对应的第二变量来发送的，也即网络设备接收到的随机接入信道是终端设备针对不同类型的随机接入信道传输机会确定的每种类型的随机接入信道传输机会下用于传输的变量，并根据该变量发送随机接入信道的。
在一些实施例中，对第一类型传输机会和第二类型传输机会、第一变量和第二变量的具体介绍见上述“1.第一类型传输机会”、“2.第二类型传输机会”和“3.第一变量与第二变量”，在此不再赘述。
在一些实施例中，在随机接入过程中，对随机接入信道的传输结果的一个较大的影响因素为接收功率。若随机接入信道的接收功率过小，容易导致网络无法接收到该终端设备发送的随机接入信道，此时可以视为随机接入信道传输失败。在终端设备判定传输失败的情况下，将对随机接入信道的接收功率执行功率爬升，并基于爬升后的接收功率再次发送随机接入信道直至传输次数达到最大传输次数。而针对支持使用两种传输资源类型的终端设备而言，在随机接入过程中通常会分别使用两种传输资源类型来发送随机接入信道。
在一种可能的实现方式中，在每次随机接入信道传输时，终端设备任意选择第一类型传输机会和第二类型传输机会。
在另一种可能的实现方式中，终端设备使用其中一种类型的传输机会(第一类型传输机会或第二类型传输机会)达到一定次数后，可以切换到另外一种类型的传输机会进行传输。如，终端设备使用第一类型传输机会传输了n次随机接入信道后，切换为使用第二类型传输机会。第一类型传输机会与第二类型传输机会的传输次数是相同的或不同的。
无论是上述两种实现方式中的哪种实现方式，都需要考虑如何设计随机接入信道的接收功率的计算方式，也即设计随机接入信道的功率控制方式。
接收功率的计算方式一：累加；
接收功率的计算方式二：基于偏移值的功率爬升；
接收功率的计算方式三：和积。
对于接收功率而言，在本次传输失败可能会提高接收功率再次尝试随机接入信道的传输，而接收功率的提升(也可以称为功率爬升、接收功率的抬升等)主要涉及的两个变量是功率爬升计数器和功率爬升步长。因此在设计时也可以基于这两个变量进行设计。首先为第一类型传输机会和第二类型传输机会分别设置一个功率爬升步长，即，第一类型传输机会对应第一功率爬升步长，第二类型传输机会对应第二功率爬升步长；还可以理解为，第一变量包括第一功率爬升步长，第二变量包括第二功率爬升步长。使不同类型的传输机会对应不同的功率爬升步长，可以更有效的进行不同类型的传输机会上的干扰管理。如位于SBFD符号中的第二类型传输机会而言，在该传输机会上发送的随机接入信道可能会对下行传输(如使用SBFD符号中的下行子带的传输)产生干扰，因此针对第二类型传输机会的功率爬升步长可以设置的小一些来避免对同符号的下行传输的干扰。需要说明的是，针对本申请实施例提供的接收功率的计算方式而言，第一类型传输机会与第二类型传输机会对应相同的功率爬升步长的情况也是适用的，本申请实施例以第一类型传输机会与第二类型传输机会对应不同功率爬升步长的情况来举例说明，但本申请实施例的保护范围不限于此。
此时，随机接入信道的接收功率基于第一功率爬升步长和第二功率爬升步长中的至少之一确定，也即第一变量或第二变量包括的接收功率基于第一功率爬升步长和第二功率爬升步长中的至少之一确定。其中，若随机接入信道在第一类型传输机会中传输，则随机接入信道的接收功率为第一变量中的接收功率；若随机接入信道在第二类型传输机会中传输，则随机接入信道的接收功率为第二变量中的接收功率。
在基于第一变量包括第一功率爬升步长和第二变量包括第二功率爬升步长的基础上，存在两种设计思路，设计思路一是第一类型传输机会和第二类型传输机会对应相同的功率爬升计数器，设计思路二则是第一类型传输机会和第二类型传输机会分别对应一个功率爬升计数器(即对应不同的功率爬升计数器)。
其中，接收功率的计算方式一、接收功率的计算方式二和接收功率的计算方式三的具体实现过程见上述加粗标题对应的内容，如“接收功率的计算方式一：累加”、“接收功率的计算方式二：基于偏移值的计算”与“接收功率的计算方式三：和积”，在此不再加以赘述。
在一些实施例中，针对终端设备选择第一类型传输机会或第二类型传输机会来传输随机接入信道的两种实现方式，尤其是第二种使用其中一种类型的传输机会(第一类型传输机会或第二类型传输机会)达到一定次数后，可以切换到另外一种类型的传输机会进行传输的实现方式，需要为终端设备设置相关变量以支持终端设备判断何时改变所使用的RO的类型。
随机接入信道对应的随机接入信道传输机会类型基于随机接入前导码传输计数器确定，随机接入信道传输机会类型包括第一类型和第二类型，第一类型的随机接入信道传输机会为第一类型传输机会，第二类型的随机接入信道传输机会为第二类型传输机会。
具体判断方式见上述“判断方式一：一个随机接入前导码传输计数器”和“判断方式二：两个随机接入前导码传输计数器”，在此不再加以赘述。
