R18研究将对LTE/GSM-R的部分专用频谱(n8，n26，n28以及n100)支持NR技术，这些频谱主要为部分国家和地区的电力系统/铁路系统、公共保护和救灾等专用业务提供通信服务，这些频谱仅 支持15KHz子载波间隔，支持的系统带宽包括5MHz和3MHz。根据NR和LTE对于RF信道带宽的规定，5MHz可用RB个数为25个；根据LTE对RF信道带宽的规定，3MHz可用RB个数为15个。
然而，现有NR系统中，PBCH占用20个RB进行传输，对3MHz(15个RB)以及2.8MHz～3.6MHz的专网系统，缺少对PBCH传输相关的定义，一种可能的方式是，PBCH仍然占用20个RB，基站/终端进行部分RB的发送/接收，将造成PBCH传输性能的损失，因此，对于3MHz以及2.8MHz～3.6MHz的专用系统，需要考虑如何进行PBCH传输以及如何提高PBCH的传输性能。
为此，本公开提出了一种通信控制方法、装置、通信设备及存储介质，旨在提供一种PBCH传输方式以匹配专用频谱的系统带宽和/或信道带宽，同时保证PBCH的传输性能。

在本公开的实施例中，第二RB用于传输第二SSB，其与当前协议相匹配，例如第二RB的个数为20个；第一RB用于传输第一SSB，其与系统带宽和/或信道带宽相匹配，例如第一RB的个数为15个，第一RB的个数小于第二RB的个数，即本公开中系统带宽或信道带宽所支持的时频资源低于当前NR协议所支持的SSB传输时频资源。其中，本公开以LTE中针对3MHz系统带宽或信道带宽可用15个RB的规定为例进行说明，应当理解的是，本公开举例的3MHz系统带宽或信道带宽与所匹配的RB个数之间的对应关系并不局限于此，协议允许或可实现的其他对应关系包括在本公开的范围内。类似地，对于2.8MHz～3.6MHz的专网系统所匹配的RB个数在本公开中不进行具体限制，以实际需要时确定的RB个数为准。
应当说明的是，在现有NR系统中，SSB在频域占据20个RB，其中物理广播信道PBCH在频域占据20个RB，PSS(Primary Synchronization Signal，主同步信号)和SSS(Secondary Synchronization Signal，辅同步信号)在频域上均占用127个RE。
进一步的，第二SSB的时频资源为现有NR协议R15/16/17中支持传输SSB的时频资源，现有NR协议中的SSB传输频域资源占据20个RB，也就是说，第二RB的个数为第二SSB在频域占据的RB个数，或者第二SSB中PBCH在频域占据的RB个数，即20个。
在本公开的实施例中，系统带宽或信道带宽所支持的时频资源低于当前NR协议所支持的SSB传输占用的时频资源，例如部分专用频谱的系统带宽或信道带宽为3MHz以及2.8MHz～3.6MHz，支持RB个数小于20个。
进一步的，第一SSB的时频资源为系统带宽/信道带宽相匹配的时频资源，例如第一RB与3MHz的系统带宽匹配，根据LTE对RF channel带宽的规定，3MHz可用RB个数为15个，不支持现有NR系统的SSB传输(频域占据20个RB)，第一RB的个数为第一SSB在频域占据的RB个数，或者第一SSB中PBCH在频域占据的RB个数，最大为15个。
综上，根据本公开实施例提供的通信控制方法，网络设备以与系统带宽和/或信道带宽相匹配的第一资源块RB，向用户设备UE发送第一同步广播块SSB，第一SSB中至少包括物理广播信道PBCH，其中第一RB的个数小于第二RB的个数，第二RB为传输第二SSB的时频资源，提出了一种SSB传输方法以匹配专用频谱的系统带宽和/或信道带宽。

S201，根据第二RB进行速率匹配，以确定与第二RB相匹配的编码比特的长度。
S202，针对与第二RB相匹配的编码比特进行调制，根据第二RB，将调制后得到的符号数据进行资源映射，以确定与第二RB相匹配的符号数据的传输位置。
应当说明的是，在本实施例中根据第二RB进行速率匹配、调制以及资源映射，为现有协议中规定内容，为了获取与第二RB相匹配的符号数据的传输位置，用于后续确定第一RB的符号数据的传输位置。
换言之，网络设备依旧根据现有NR协议支持R15/16/17中传输SSB的时频资源(SSB在频域占据20个RB)，进行速率匹配、QPSK调制以及资源映射，或者说，网络设备依旧根据所述传统SSB中PBCH的时频域资源结构(PBCH在频域占据20个RB)，进行速率匹配、QPSK调制以及资源映射。
具体地，根据现有20个RB的SSB时频资源结构/SSB中的PBCH时频资源结构进行速率匹配，输出比特长度为864比特，针对864编码比特进行QPSK调制，并且，根据现有20个RB的PBCH时频资源结构，将调制后得到的符号数据进行资源映射，可以确定所述符号数据的传输位置。
在一些实施例中，还包括：确定所述第一RB，其中，所述第一RB的个数等于或小于所述系统带宽和/或信道带宽所支持的最大时频资源对应的RB个数。
可以理解的是，为解决现有协议R18对LTE/GSM-R的部分专用频谱支持NR技术提供通信服务的问题，本公开中的所述系统带宽和/或信道带宽包括3MHz的专用网络系统带宽和/或2.8MHz～3.6MHz的专用网络系统带宽，第一RB可以与3MHz和/或2.8MHz～3.6MHz的系统带宽和/或信道带宽相匹配。
举例而言，第一RB与3MHz的系统带宽和/或信道带宽相匹配，3MHz的系统带宽和/或信道带宽可用RB为15个，即所支持的最大时频资源为15个，第一RB的个数等于或小于15。
S203，从与第二RB相匹配的符号的传输位置中，选择SSB中心频点处的第一RB个数的符号的传输位置，以向UE发送第一SSB。
换言之，从与现有R15/16/17 NR协议支持传输SSB/PBCH的时频资源(5MHz系统宽带，SSB在频域占据20个RB)相匹配的符号的传输位置中，选择SSB中心频点处的与系统带宽和/或信道带宽匹配的时频资源(例如专用网络系统的3MHz系统宽带，SSB在频域占据15个RB)相匹配个数的符号的传输位置。
其中，所述SSB中心频点处指现有NR系统中SSB时频资源结构的中心频点附近。
在一些具体实施方式中，如图3所示，左侧第一个为现有NR中PBCH的时频资源结构，在频域上占20个RB，选择与3MHz系统带宽相匹配的RB，选择中心频点附近的15个RB，舍弃边缘的5个RB，具体可以包括如图3所示(a)、(b)、(c)以及(d)中的4种选择方式，如图3所示，右侧为选择出的与3MHz系统宽带相匹配的PBCH的时频资源结构，在频域占据15个RB。
在本公开的一些实施例中，还包括：确定第一SSB所在的第一RB的第一子载波索引，其中第一子载波索引为相对第一RB内子载波0的偏移。
换言之，第一SSB所在的第一RB中的每个子载波的索引位置相对于现有NR系统的SSB构的资源映射表格进行偏移，参考点为第一RB内子载波0，现有NR系统的SSB时频结构的资源映射表格如表1所示。
如表1示出了现有NR系统的SSB中各信号或信道具体的时频域位置，其中，l表示时域符号索引(l＝0，1，2，3)，k表示频域RE索引，即子载波索引(参考点为SSB RB0的RE0，即SSB中RB0内子载波0，k＝0，1，2…，239)。
表1：一个SS/PBCH块中PSS、SSS、PBCH以及PBCH的DM-RS的资源
在一种实现方式中，选择中心频点附近的第一RB个数的RB作为第一RB，重新确定第一RB的子载波索引，其中，第一RB的第一子载波索引＝第二RB的子载波索引-offset，或者说，第一SSB的子载波索引＝第二SSB的子载波索引-offset。其中，offset可以通过但不限于下述方式确定：offset＝(20-M)/2*12，或offset＝ceil((20-M)/2*12),或offset＝floor((20-M)/2*12)，其中M为PBCH实际的传输RB个数，也即第一RB个数。
步骤203还包括以下两种可选的实现方式：
本公开的一些实施例中，保留SSB中心频点处第一RB上每个子载波承载的符号数据，并将超出第一RB上每个子载波承载的符号数据置0；按照SSB中心频点处的第一RB的第一子载波索引及其相应的符号数据，进行正交频分复用OFDM调制，以向UE发送第一SSB。
另一些实施例中，确定SSB中心频点处的第二RB的第二子载波索引；将第二子载波索引替换为第一子载波索引；按照SSB中心频点处的第一RB的第一子载波索引及其相应的符号数据，进行OFDM调制，以向UE发送第一SSB。
换言之，在进行OFDM调制时，保留与系统带宽相匹配的RB上的原始符号数据，其他超出系统带宽部分的RE置0，或者，对于步骤202中根据第二RB资源映射后的子载波索引，确定SSB中心频点处的子载波索引，并将其替换为第一子载波索引，按照SSB中心频点处的第一子载波索引及其相应的符号数据，进行OFDM调制。
综上，根据本公开实施例提供的通信控制方法，根据第二RB进行速率匹配，以确定与第二RB相匹配的编码比特的长度，针对与第二RB相匹配的编码比特进行调制，根据第二RB，将调制后得到的符号数据进行资源映射，以确定与第二RB相匹配的符号数据的传输位置，从与第二RB相匹配的符号的传输位置中，选择SSB中心频点处的第一RB个数的符号的传输位置，以向UE发送第一SSB，提出了一种SSB/PBCH传输方式以匹配专用频谱的系统带宽和/或信道带宽，同时保证PBCH的传输性能。
图4示出了根据本公开实施例的一种通信控制方法的流程示意图。该方法应用于网络设备，基于图1和图2所示实施例，如图4所示，该方法可以包括以下步骤。
S301，根据第二RB进行速率匹配，以确定与第二RB相匹配的编码比特的长度。
S302，针对与第二RB相匹配的编码比特进行调制，根据第二RB，将调制后得到的符号数据进行资源映射，以确定与第二RB相匹配的符号数据的传输位置。
应当说明的是，在本实施例中根据第二RB进行速率匹配、调制以及资源映射，为现有协议中规定内容，为了获取与第二RB相匹配的符号数据的传输位置，用于后续确定第一RB的符号数据的传输位置。
换言之，网络设备依旧根据现有NR协议支持R15/16/17传输SSB的时频资源(SSB在频域占据20个RB)，进行速率匹配、QPSK调制以及资源映射，或者说，网络设备依旧根据所述传统SSB中PBCH的时频域资源结构(PBCH在频域占据20个RB)，进行速率匹配、QPSK调制以及资源映射。
具体地，根据现有20个RB的SSB时频资源结构/SSB中的PBCH时频资源结构进行速率匹配，输出比特长度为864比特，针对864编码比特进行QPSK调制，并且，根据现有20个RB的PBCH时频资源结构，将调制后得到的符号数据进行资源映射，可以确定所述符号数据的传输位置。
在一些实施例中，还包括：确定所述第一RB，其中，所述第一RB的个数等于或小于所述系统带宽和/或信道带宽所支持的最大时频资源对应的RB个数。
可以理解的是，为解决现有协议R18对LTE/GSM-R的部分专用频谱支持NR技术提供通信服务的问题，本公开中的所述系统带宽和/或信道带宽包括3MHz的专用网络系统宽带和/或2.8MHz～3.6MHz的专用网络系统宽带，第一RB可以与3MHz和/或2.8MHz～3.6MHz的专用系统带宽和/或信道带宽相匹配。
举例而言，第一RB与3MHz的系统带宽和/或信道带宽相匹配，3MHz的系统带宽和/或信道带宽可用RB为15个，即所支持的最大时频资源为15个，第一RB的个数等于或小于15。
S303，将与第二RB相匹配的符号数据，重映射至第一RB上。
可以理解的是，由于第二RB的个数大于第一RB，将与第二RB相匹配的符号数据重映射至第一RB上，需要对第二RB进行部分选择，步骤303相较于步骤S203，不同于选择SSB中心频点处与系统带宽和/或终端信道带宽相匹配的RB，步骤303可以通过不同的PBCH资源重映射图样，对与第二RB相匹配的符号数据重映射到与系统带宽和/或终端信道带宽相匹配的RB上，重新映射后符号对应的传输位置在SSB中心频点处。
如图5所示，pattern#1、pattern#2为本公开列举出的两种不同的PBCH资源重映射图样，其中，pattern#1左侧为与第二RB相匹配的符号数据，舍弃了顶端的部分RB，将保留下来的符号数据重映射到如右侧所示的第一RB上，在SSB中心频点处，pattern#2左侧为与第二RB相匹配的符号数据，舍弃了底端的部分RB，将保留下来的符号数据重映射到如右侧所示的第一RB上，在SSB中心频点处。
在本公开的一些实施例中，针对至少两次不同的PBCH传输，使用不同的PBCH资源重映射图样，将与第二RB相匹配的符号数据重映射至第一RB上。
进一步的，至少两次不同的PBCH传输包括：同一SSB周期内的SSB集内任意两个或多个SSB索引对应的PBCH传输；或者，至少两个不同SSB周期对应的相同SSB索引对应的PBCH传输。
举例而言，在80ms内重复4个周期的PBCH传输，在同一周期内，PBCH传输要发送4个不同的SSB索引，可以在同一周期内的两个或多个SSB索引对应的PBCH传输中使用不同的PBCH资源重映射图样，例如在第一个SSB索引对应的PBCH传输使用pattern#1，第二个SSB索引对应的PBCH传输使用pattern#2，对于其余2个SSB索引对应的PBCH传输依次使用pattern#1、pattern#2。也可以在至少两个不同SSB周期对应的相同SSB索引对应的PBCH传输，例如在第一个周期的第一个SSB索引对应的PBCH传输使用pattern#1，在在第三个周期的第一个SSB索引对应的PBCH传输使用pattern#2。
进一步的，网络设备可以使用两种或多种资源重映射pattern循环进行PBCH的传输，例如按照pattern#1、pattern#2、pattern#1、pattern#2…….的顺序循环进行PBCH的传输。
在本公开的一些实施例中，该方法还包括：向UE配置至少两次不同的PBCH传输所使用的不同的PBCH资源重映射图样的图样相关信息。
其中，至少两次不同的PBCH传输包括：同一SSB周期内的SSB集内任意两个或多个SSB索引对应的PBCH传输；或者，至少两个不同SSB周期对应的相同SSB索引对应的PBCH传输。
举例而言，可由网络设备向UE配置或指示每次SSB传输PBCH的资源重映射pattern，如指示为{Pattern 2，pattern 1}，或指示起始pattern为pattern#2，这意味着在一个固定周期内的不同SSB传输，第一个PBCH按照pattern#2进行资源重映射，第二个PBCH按照pattern#1进行资源重映射，以此往复。
S304，以与系统带宽和/或信道带宽相匹配的第一RB，向UE发送第一SSB。
其中，第一RB的个数等于或小于系统带宽和/或信道带宽所支持的最大时频资源对应的RB个数
在本公开的一些实施例中，该方法还包括：确定第一SSB所在的第一RB的第一子载波索引，其中第一子载波索引为相对第一RB内子载波0的偏移。
在一种实现方式中，选择中心频点附近的第一RB个数的RB作为第一RB，重新确定第一RB的子载波索引，其中，第一RB的第一子载波索引＝第二RB的子载波索引-offset，或者说，第一SSB的 子载波索引＝第二SSB的子载波索引-offset。其中，offset可以通过但不限于下述方式确定：offset＝(20-M)/2*12，或offset＝ceil((20-M)/2*12),或offset＝floor((20-M)/2*12)，其中M为PBCH实际的传输RB个数，也即第一RB个数。
在本公开的一些实施例中，以与系统带宽和/或信道带宽相匹配的第一RB，向UE发送第一SSB包括：保留SSB中心频点处重映射后的第一RB上每个子载波承载的符号数据，并将超出重映射后的第一RB上每个子载波承载的符号数据置0；按照SSB中心频点处的第一RB的第一子载波索引及其相应的符号数据，进行正交频分复用OFDM调制，以向UE发送第一SSB。
在本公开的一些实施例中，以与系统带宽和/或信道带宽相匹配的第一RB，向UE发送第一SSB包括：确定SSB中心频点处的第二RB的第二子载波索引；将第二子载波索引替换为第一子载波索引；按照SSB中心频点处的第一RB的第一子载波索引及其相应的重映射后的符号数据，进行OFDM调制，以向UE发送第一SSB。
换言之，在进行OFDM调制时，保留与系统带宽相匹配的RB上的原始符号数据，其他超出系统带宽部分的RE置0，按照SSB中心频点处的第一子载波索引及其相应的符号数据，进行OFDM调制，或者，或者，对于步骤302中根据第二RB资源映射后的子载波索引，确定SSB中心频点处的子载波索引，并将其替换为第一子载波索引，按照SSB中心频点处的第一子载波索引及相应的重映射后的符号数据，进行OFDM调制。
综上，根据本公开实施例提供的通信控制方法，根据第二RB进行速率匹配，以确定与第二RB相匹配的编码比特的长度，针对与第二RB相匹配的编码比特进行调制，根据第二RB，将调制后得到的符号数据进行资源映射，以确定与第二RB相匹配的符号数据的传输位置，将与第二RB相匹配的符号数据，重映射至第一RB上，以与系统带宽和/或信道带宽相匹配的第一RB，向UE发送第一SSB，提出了一种SSB/PBCH传输方式以匹配专用频谱的系统带宽和/或信道带宽，同时保证PBCH的传输性能。

S401，确定第一SSB所在的第一RB的第一子载波索引，其中第一子载波索引为相对第一RB内子载波0的偏移。
换言之，第一SSB所在的第一RB中的每个子载波的索引位置相对于现有NR系统的SSB构的资源映射表格进行偏移，参考点为第一RB内子载波0，现有NR系统的SSB时频结构的资源映射表格如表1所示。
在一种实现方式中，选择中心频点附近的第一RB个数的RB作为第一RB，重新确定第一RB的子载波索引，其中，第一RB的第一子载波索引＝第二RB的子载波索引-offset，或者说，第一SSB的子载波索引＝第二SSB的子载波索引-offset。其中，offset可以通过但不限于下述方式确定：offset＝(20-M)/2*12，或offset＝ceil((20-M)/2*12),或offset＝floor((20-M)/2*12)，其中M为PBCH实际的传输RB个数，也即第一RB个数。
在本公开的一些实施例中，该方法还包括：确定第一RB，其中，第一RB的个数等于或小于系统带宽和/或信道带宽所支持的最大时频资源对应的RB个数。
可以理解的是，为解决现有协议R18对LTE/GSM-R的部分专用频谱支持NR技术提供通信服务的问题，本公开中的所述系统带宽和/或信道带宽包括3MHz的专用网络系统宽带和/或2.8MHz～3.6MHz的专用网络系统宽带，第一RB可以与3MHz和/或2.8MHz～3.6MHz的系统带宽和/或信道带宽相匹配。

S404，以所述第一RB，向UE发送第一SSB。
换言之，网络设备根据与系统带宽/终端带宽相匹配的时频资源(例如3MHz系统带宽，SSB在频域占据15个RB)，进行速率匹配、QPSK调制以及资源映射。
具体地，根据15个RB的SSB时频资源结构/SSB中的PBCH时频资源结构进行速率匹配，输出比特长度为594比特，针对594编码比特进行QPSK调制，将调制后得到的符号数据进行资源映射，可以确定所述符号数据的传输位置，其中，资源映射按照偏移后的SSB时频结构的资源映射表格进行。
在本公开的一些实施例中，根据第一RB进行速率匹配包括：针对至少两次不同的PBCH传输，采用相同的编码比特起始位置进行速率匹配。
举例而言，根据与系统带宽/终端带宽相匹配的第一RB，以系统带宽/终端带宽为3MHz，第一RB的个数为15个为例，速率匹配后与传输资源相匹配的编码比特的长度为594比特，而Turbo编码后比特数为512，还有82个比特需要重复，针对至少两次不同的PBCH传输，采用相同的编码比特起始位置进行速率匹配，例如均在0比特起始位置进行，在一次PBCH传输中，将比特#0定位起始位置，PBCH传输按照从0到512，再从0到82进行，在其他不同的PBCH传输中，同样将编码比特#0定位起始位置，PBCH传输按照从0到512，再从0到82进行。
其中，至少两次不同的PBCH传输包括：同一SSB周期内的SSB集内任意两个或多个SSB索引对应的PBCH传输；或者，至少两个不同SSB周期对应的相同SSB索引对应的PBCH传输。

在本公开的一些实施例中，根据第一RB进行速率匹配包括：针对至少两次不同的PBCH传输，采用不同的编码比特起始位置进行速率匹配，其中，用于速率匹配的不同编码比特起始位置取决于与系统带宽和/或信道带宽相匹配的编码比特的长度。
举例而言，根据与系统带宽/终端带宽相匹配的第一RB，以系统带宽/终端带宽为3MHz，第一RB的个数为15个为例，速率匹配后与传输资源相匹配的编码比特的长度为594比特，Turbo编码后比特数为512，针对至少两次不同的PBCH传输，采用不同的编码比特起始位置进行速率匹配，在一次PBCH 传输中，将比特#0定位起始位置，PBCH传输按照从0到512，再从0到82进行，在其他不同的PBCH传输中，同样将编码比特#82定位起始位置，PBCH传输按照从82到512，再从0到164进行。

图7为根据本公开实施例的一种通信控制方法的流程示意图。该方法由用户设备UE执行，用户设备包括但不限于智能终端设备、蜂窝电话、无线设备、手持机、移动单元、车辆、车载设备等，本公开不予限制
如图7所示，该方法可以包括以下步骤。
S501，接收网络设备发送的与系统带宽和/或信道带宽相匹配的第一RB对应的第一同步广播块SSB，第一SSB中至少包括物理广播信道PBCH。
其中，第一RB的个数小于第二RB的个数，第二RB为传输第二SSB的时频资源。
在本公开的实施例中，所述系统带宽和/或信道带宽还可以为可用带宽资源，在本公开中不予限制。
在本公开的实施例中，第二RB用于传输第二SSB，其与当前协议相匹配；第一RB用于传输第一SSB，其与系统带宽和/或信道带宽相匹配，第一RB的个数小于第二RB的个数，即本公开中系统带宽或信道带宽所支持的时频资源低于当前协议所支持的SSB传输时频资源。
应当说明的是，在现有NR系统中，SSB在频域占据20个RB，其中物理广播信道PBCH在频域占据20个RB，PSS(Primary Synchronization Signal，主同步信号)和SSS(Secondary Synchronization Signal，辅同步信号)在频域上均占用127个RE。
进一步的，第二SSB的时频资源为现有NR协议R15/16/17中支持传输SSB的时频资源，现有NR协议中的SSB传输(频域资源占据20个RB)，也就是说，第二RB的个数为第二SSB在频域占据的RB个数，或者第二SSB中PBCH在频域占据的RB个数，即20个。
在本公开的实施例中，系统带宽或信道带宽所支持的时频资源低于当前协议所支持的SSB传输占用的时频资源，例如部分专用频谱的系统带宽或信道带宽在3MHz以及2.8MHz～3.6MHz，支持RB个数小于20个。
进一步的，第一SSB的时频资源为系统带宽/信道带宽相匹配的时频资源，例如第一RB与3MHz的系统带宽匹配，根据LTE对RF channel带宽的规定，3MHz可用RB个数为15个，不支持现有NR系统的SSB传输(频域占据20个RB)，第一NR的个数为第一SSB在频域占据的RB个数，或者第一SSB中PBCH在频域占据的RB个数，最大为15个。
综上，根据本公开实施例提供的通信控制方法，接收网络设备发送的与系统带宽和/或信道带宽相匹配的第一RB对应的第一同步广播块SSB，第一SSB中至少包括物理广播信道PBCH，其中，第一RB的个数小于第二RB的个数，第二RB为传输第二SSB的时频资源，提出了一种SSB传输方式配专用频谱的系统带宽和/或信道带宽。
图8示出了根据本公开实施例的一种通信控制方法的流程示意图。该方法应用于UE，基于图7所示实施例，如图8所示，该方法可以包括以下步骤。
S601，接收网络设备发送的与系统带宽和/或信道带宽相匹配的第一RB对应的第一SSB，第一SSB中至少包括PBCH。
在本公开的一些实施例中，该方法还包括：对PBCH进行OFDM解调；根据协议约定确定第一SSB的RE索引重排序方式，基于第二SSB的RE索引位置和RE索引重排序方式，确定OFDM解调符号所位于的与第二RB相匹配的符号数据的传输位置。
可以理解的是，在网络设备侧，对第二SSB的RE索引进行了重排序来确定第一SSB的RE索引，UE可以根据协议约定确定第一SSB的RE索引重排序方式，基于第二SSB的RE索引位置和第一SSB的RE索引重排序方式，确定OFDM解调符号所位于的与第二RB相匹配的符号数据的传输位置。
在一种实现方式中，在OFDM解调之前，还可以包括：根据与系统带宽和/或信道带宽的宽度相匹配的滤波器对接收PBCH进行数字滤波，以排除当前系统带宽和/或信道带宽的网络与其相邻网络之间子载波的干扰。进一步的，得到滤波后的接收PBCH，解OFDM后，与终端信道带宽/系统带宽相匹配的频域位置保持原始数据不变，其他位置0。
S602，根据第二RB进行解资源映射和解速率匹配。
在本公开的一些实施例中，在根据第二RB进行解资源映射和解速率匹配之前，该方法还包括：对第一RB上的符号数据进行解资源重映射。
可以理解的是，对应于图4所示实施例中步骤S303，将与第二RB相匹配的符号数据，重映射至第一RB上，符号数据的传输位置发生了改变，不能直接根据第二RB进行解资源映射和解速率匹配， 需要对第一RB上的符号数据进行解资源重映射。换言之，执行与网络设备侧对应的资源重映射的反向过程，进而确定符号数据所在的原始资源位置。
进一步的，对应于图2和图4所示实施例中，网络设备根据第二RB进行速率匹配、QPSK调制以及资源映射的情形，UE在接收到网络设备发送的第一SSB后，根据第二RB进行解资源映射和解速率匹配。换言之，根据现有NR协议R15/16/17中支持传输SSB的时频资源，进行解速率匹配和解资源映射。
在本公开的一些实施例中，该方法还包括：针对至少两次不同的PBCH传输，进行单独译码或者合并译码。
举例而言，针对至少两次不同的PBCH传输，可以将至少两次不同的PBCH传输解速率匹配的内容叠加，叠加后一起进行译码，也可以对每次接收到的PBCH传输分别单独译码。
应当说明的是，在SSB发送周期内，会进行重复的PBCH传输，例如每80毫秒内，进行重复的四次PBCH传输，UE对两次或多次PBCH接收进行合并译码，可以提高PBCH传输性能。
在本公开的一些实施例中，针对至少两次不同的PBCH传输，进行合并译码包括：针对使用不同的PBCH资源重映射图样的至少两次不同的PBCH传输，在初始接入状态下，以预设的图样顺序进行合并译码。
应当说明的是，对应于图4所示实施例中，网络设备侧针对至少两次不同的PBCH传输，使用不同的PBCH资源重映射pattern，考虑到在初始接入状态下，UE无法获知当前时刻所接收的PBCH是第几个PBCH，因此进行盲合并解码，即以预设的图样顺序进行合并译码。
例如，对于两次PBCH接收，考虑首先按照{pattern 1，pattern#2}对应于先后接收的{PBCH#1，PBCH#2}来进行解资源映射与解速率匹配，然后进行HARQ合并，如果解码不成功，再次按照{pattern#2,pattern#1}对应于先后接收的{PBCH#1，PBCH#2}来进行解资源映射与解速率匹配，然后进行合并译码。
应当说明的是，如果网络设备侧采用两个或多个重映射pattern用于PBCH传输，UE侧若对于单个PBCH接收尝试译码，可以考虑匹配两个或多个资源重映射pattern盲解码方式。
在本公开的一些实施例中，针对至少两次不同的PBCH传输，进行合并译码包括：针对使用不同的PBCH资源重映射图样的至少两次不同的PBCH传输，在非初始接入状态下，根据协议约定的或者网络设备配置的图样相关信息进行合并译码。

图9示出了根据本公开实施例的一种通信控制方法的流程示意图。该方法应用于UE，基于图7所示实施例，如图9所示，该方法可以包括以下步骤。
S701，接收网络设备发送的与系统带宽和/或信道带宽相匹配的第一RB对应的第一同步广播块SSB，第一SSB中至少包括物理广播信道PBCH。
在本公开的一些实施例中，该方法还包括：对PBCH进行OFDM解调；根据协议约定确定第一SSB的RE索引重排序方式，基于第二SSB的RE索引位置和RE索引重排序方式，确定OFDM解调符号所位于的与第二RB相匹配的符号数据的传输位置。
可以理解的是，在网络设备侧，对第二SSB的RE索引进行了重排序来确定第一SSB的RE索引，UE可以根据协议约定确定第一SSB的RE索引重排序方式，基于第二SSB的RE索引位置和第一SSB的RE索引重排序方式，确定OFDM解调符号所位于的与第二RB相匹配的符号数据的传输位置。

S702，根据第一RB进行解资源映射和解速率匹配。
可以理解的是，对应于图6所示实施例中，网络设备根据第一RB进行速率匹配、QPSK调制以及资源映射的情形，UE在接收到网络设备发送的第一SSB后，根据第一RB进行解资源映射和解速率匹配。换言之，根据与系统带宽和/或信道带宽相匹配的时频资源，进行解速率匹配和解资源映射。

举例而言，针对至少两次不同的PBCH传输，可以将至少两次不同的PBCH传输解速率匹配的内容叠加，叠加后一起进行译码，也可以对每次接收到的PBCH传输分别单独译码。

应当说明的是，对应于图6所示实施例中，网络设备侧针对至少两次不同的PBCH传输，采用不同的编码比特起始位置进行速率匹配，考虑到在初始接入状态下，UE无法获知当前时刻所接收的PBCH是第几个PBCH，因此进行盲合并解码，即以预设的编码比特起始位置循环顺序进行合并译码。
例如，对PBCH#1,PBCH#2首先假设编码比特起始位置循环顺序为A,B进行合并解码；若尝试不成功，则再交换编码比特起始位置循环顺序假设再次尝试进行合并解码。
应当说明的是，如果网络设备侧采用两个或多个重映射pattern用于PBCH传输，UE侧若对于单个PBCH接收尝试译码，可以考虑匹配两个或多个资源重映射pattern盲解码方式。
在本公开的一些实施例中，针对至少两次不同的PBCH传输，进行合并译码包括：针对使用不同的编码比特起始位置循环顺序的至少两次不同的PBCH传输，在非初始接入状态下，根据协议约定的或者网络设备配置的编码比特起始位置循环顺序进行合并译码。

在本公开的一些实施例中，该方法还包括：根据编码比特起始位置循环顺序以及下行定时，确定每次PBCH速率匹配所使用的编码比特起始位置。
换言之，UE根据PBCH传输的下行定时和编码比特起始位置循环顺序，可以确定当前时刻所接收的PBCH是第几个PBCH以及与之对应的编码比特起始位置循环顺序。
在本公开的一些实施例中，上述至少两次不同的PBCH传输包括：同一SSB周期内的SSB集内任意两个或多个SSB索引对应的PBCH传输；或者，至少两个不同SSB周期对应的相同SSB索引对应的PBCH传输。
举例而言，在80ms内重复4个周期的PBCH传输，在同一周期内，PBCH传输要发送4个不同的SSB索引，至少两次不同的PBCH传输可以指同一周期内的任意2个或3个或4个不同的SSB索引对应的PBCH传输，也可以指在任意2个或3个或4个不同的周期对应的相同SSB索引对应的PBCH传输。
综上，根据本公开实施例提供的通信控制方法，UE接收网络设备发送的与系统带宽和/或信道带宽相匹配的第一RB对应的第一SSB，根据第一RB进行解资源映射和解速率匹配，针对至少两次不同的PBCH传输，进行单独译码或者合并译码，提出了一种SSB/PBCH传输方式以匹配专用频谱的系统带宽和/或信道带宽，同时保证PBCH的传输性能。
