Description

一种指示信息的传输方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种指示信息的传输方法及装置。
背景技术
随着通信技术的快速发展，人们对无线通信的数据速率和效率的要求越来越高。在5G新无线(New Radio，NR)通信系统中，波束成形技术用来将传输信号的能量限制在某个波束方向内，从而增加信号发射和接收的效率。波束成形技术能够有效扩大无线信号的传输范围，降低信号干扰，从而达到更高的通信效率和获取更高的网络容量。因此物理广播信道(physical broadcast channel，PBCH)的数据传输需要进行波束扫描，而且PBCH的数据解调要求是高可靠性，因此PBCH的码率至少为1/12，因此1bit的PBCH数据，经过编码之后变为12bits的数据，增大了12倍。因此降低PBCH的开销具有极其重要的意义。
发明内容
本申请提供一种指示信息的传输方法及装置，以减小PBCH的开销。
一方面，公开了一种指示信息的传输方法，包括：
网络设备生成同步信号块(synchronization signal，SS block)，所述SS block包括同步信号(synchronization signal，SS)资源块及物理广播信道PBCH资源块，其中，所述PBCH资源块中的X比特用于指示10ms帧的前半帧和后半帧，以及多种同步信号段集合SS burst set周期中至少一种；发送所述SS block。
同步信号SS资源块可以包括PSS及SSS资源块中至少一种。
例如：X＝3，所述10ms帧的前半帧和后半帧为5ms SS burst set周期的10ms帧的前半帧和后半帧，所述多种SS burst set周期包括以下至少一种：5ms，10ms，20ms，40ms，80ms，160ms。
与上述一方面对应，公开了一种指示信息的传输方法，包括：
终端设备接收SS block，所述SS block包括SS资源块及PBCH资源块，其中，所述PBCH资源块中的X比特用于指示10ms帧的前半帧和后半帧，以及多种同步信号段集合SS burst set周期中至少一种；解调PBCH资源块获取相应的SS burst set的周期和/或半帧信息。
以上方案中，X比特位于PBCH的MIB中。
以上方案中，一个帧是10ms，网络设备生成SS block，所述SS block包括主同步 信号PSS，辅同步信号SSS及PBCH资源块，其中，所述PBCH资源块中的3比特用于指示5ms SS burst set的前半帧，5ms SS burst set的后半帧，以及5种SS burst set周期，发送所述SS block。终端设备接收所述SS block，解调PBCH资源块获取相应的SS burst set的周期和半帧信息。另外，如果终端设备为初始接入，先根据SS block中的SS进行同步。
所述5种SS burst set周期可以包括：10ms，20ms，40ms，80ms，160ms。
上述方案中，将半帧信息与多个SS burst set的周期一起进行指示，节省了PBCH开销。
相应的，还公开一种网络设备，包括：
处理模块：用于生成同步信号块SS block，所述SS block包括同步信号SS资源块及物理广播信道PBCH资源块，其中，所述PBCH资源块中的X比特用于指示10ms帧的前半帧、10ms帧的后半帧，以及多种同步信号段集合SS burst set周期中至少一种；
发送模块：用于发送所述SS block。
一种终端设备，包括：
接收模块：用于接收SS block，所述SS block包括SS资源块及PBCH资源块，其中，所述PBCH资源块中的X比特用于指示10ms帧的前半帧、10ms帧的后半帧，以及多种同步信号段集合SS burst set周期中至少一种；
处理模块：用于解调PBCH资源块获取相应的SS burst set的周期和/或半帧信息。
上述网络设备与终端设备与第一方面中的网络设备及终端设备完全对应，由相应的模块执行相应的步骤，例如发送模块执行方法实施例中发送类的步骤，接收模块执行方法实施例中接收类的步骤，其它步骤由处理模块实现，具体内容参考上述方法，不再详述。
第二方面，公开了一种指示信息的传输方法，包括：
网络设备生成同步信号块SS block，所述SS block包括同步信号SS资源块及物理广播信道PBCH资源块，发送所述SS block；
其中，PBCH资源块中的X比特用于指示SS block的数目和/或时间索引，N-X比特用于指示系统帧号；在不同SS burst set周期下，X的取值不同，N为固定值。X，N均为整数。
SS block的数目可以为SS burst set下所有SS block的数目。
与上述二方面对应，终端设备接收所述SS block，解调PBCH资源块获取相应的SS block的数目和/或时间索引。另外，如果终端设备为初始接入，先根据SS block中的SS进行同步。
以上方案中，X比特位于PBCH的MIB中。
结合上述方面，所述SS burst set周期为5ms或10ms时，X＝5；或
所述SS burst set周期为20ms以上时，即20ms，40ms，80ms，160ms等，X＝6。
也就是说，所述SS burst set周期为5ms或10ms时，最大波束数目为32，需要5比特指示就够了，因为5比特最多32个取值；所述SS burst set周期为20ms以上时，最大波束数目为64，需要6比特，此时可以从系统帧号中借用1比特，例如借用系统帧号的最后一位，这样，节省了PBCH的开销。
例如：网络设备生成SS block，所述SS block包括PSS,SSS及PBCH资源块，其中，PBCH资源块中的5比特用于指示5ms或10ms SS burst set的SS block的数目或时间索引；所述5ms或10ms SS burst set的最大波束数目为32。
或者
PBCH资源块中的6比特用于指示20ms以上SS burst set的SS block的数目或时间索引；所述6比特中的1比特为指示系统帧号比特的最后一位，所述20ms以上的SS burst set的最大波束数目为64。
上述方案中，5ms或10ms SS burst set的最大波束数目为32，用5比特指示；20ms以上SS burst set的最大波束数目为32，需要用6比特指示，此时借用指示系统帧号的1比特，因此只需要5比特，节省了PBCH开销。
相应的，还公开一种网络设备，包括：

所述X+3比特中的2比特为指示系统帧号比特的最后2位，1比特为借用的半帧指示。
与上述三方面对应，终端设备接收所述SS block，解调PBCH资源块获取相应的SS block的数目和/或时间索引。另外，如果终端设备为初始接入，先根据SS block中的SS进行同步。
以上方案中，X比特位于PBCH的MIB中。
例如：X＝3，5ms SS burst set的最大波束数目为8，需要3比特来指示；10ms SS burst set的最大波束数目为16，需要4比特来指示，此时可以借用半帧指示的1比特；20ms SS burst set的最大波束数目为32，需要5比特来指示，此时可以借用半帧指示的1比特及系统帧号的1比特；40ms以上(包括80ms，160ms)SS burst set的最大波束数目为64，需要6比特来指示，此时可以借用半帧指示的1比特及系统帧号的2比特。
通过上述借用半帧指示及指示系统帧号比特中1比特或2比特来指示SS block的数目或时间索引，节省了PBCH的开销。

图3为本申请实施例的终端的结构示意图，该终端可以为手机、平板电脑、笔记本电脑等。如图3所示，该终端包括：存储器、处理器、射频(Radio Frequency，RF) 电路、以及电源等部件。本领域技术人员可以理解，图3中示出的结构并不构成对终端的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
下面结合图3对终端的各个构成部件进行具体的介绍：
存储器可用于存储软件程序以及模块，处理器可以通过运行存储在存储器的软件程序以及模块，从而执行终端的各种功能应用以及数据处理。存储器可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序等；存储数据区可存储根据终端的使用所创建的数据等。此外，存储器可以包括高速随机存取存储器，还可以包括非易失性存储器等。

5G NR系统当中，基站生成PSS序列和SSS序列，用于同步，又根据主要信息块(main information block，MIB)生成PBCH，将PBCH和PSS，以及SSS组成一个SS block，基站可以通过波束扫描的方式发送一个或多个SS block；终端进行初始接入时，首先检测PSS进行同步，再检测SSS获得小区标识，最后解调PBCH资源块，获得初始接入相关信息，包含同步用的系统帧号(system frame number，SFN)、半帧指示、SS block的时间索引等内容中的至少一种。在NR当中，将一个PSS OFDM符号，一个SSS OFDM符号和两个或多个PBCH OFDM符号一起构成一个资源块，将该资源块称为同步块(SS block)，SS block中PSS符号，SSS符号和PBCH符号的位置有固定的时域分布关系，而且是相邻的。数个同步块又构成同步段(SS burst)，数个SS burst又构成了一个同步段集合(SS burst set)。
PBCH里面传输MIB的内容包括：至少部分SFN、SS burst set周期，SS block时间索引，SS block数量，半帧指示等一种或几种。
目前，在NR当中，存在着6种同步信号段集合(SS burst set)周期，分别为5ms，10ms，20ms，40ms，80ms和160ms，这6种周期形式至少需要3bits进行指示，对于5ms SS burst周期，还需要1bit指示半帧信息，因此，总共需要4bits数据。
另外SS block的传输是波束扫描的，因此需要在PBCH当中指示同步块(SS block)的数目和/或时间索引，NR当中规定，最大的波束数目为64，因此SS block的数目需要6bits进行指示，SS block的时间索引也需要6bits，这两种指示造成PBCH比较大的开销。
本申请提出一种指示信息的传输方法，可以降低PBCH的开销，参考图5，该方法包括：
501、网络设备生成同步信号块SS block，所述SS block包括同步信号SS资源块及物理广播信道PBCH资源块，其中，所述PBCH资源块中的X比特用于指示10ms帧的前半帧和/或后半帧，以及多种同步信号段集合SS burst set周期中至少一种；
SS资源块可以包括PSS及SSS资源块中至少一个。
502、发送所述SS block。
一个例子中，X＝3bit，所述10ms帧的前半帧和后半帧为5ms SS burst set周期的10ms帧的前半帧和后半帧，所述多种SS burst set周期包括：5ms、10ms，20ms，40ms，80ms，160ms至少一种。同步信号SS包括PSS及SSS至少一个，同步信号SS资源块包括PSS及SSS资源块至少一个。
3个比特可以指示上述各种内容，但网络设备发送的SS block在某个时间段可能只指示其中至少一种，如，只指示10ms SS burst set周期，或只指示5ms SS burst set周期的10ms帧的前半帧。
相应的，终端设备接收SS block，所述SS block包括SS资源块及PBCH资源块，其中，所述PBCH资源块中的X比特用于指示10ms帧的前半帧和后半帧，以及多种同步信号段集合SS burst set周期；解调所述PBCH资源块获取相应的SS burst set的周期和/或半帧信息。
上述实施例中，将半帧信息与几种SS burst set周期一起进行指示，3bits数据总共有8种取值分别为：000,001,010,011,100,101,110,111，而SS burst set周期只有6种情况，5ms，10ms，20ms，40ms，80ms和160ms；一个帧是10ms，只有5ms SS burst set需要指示前半帧及后半帧，加上剩余5种SS burst周期，一共7种情况；而3bits数据总共有8种取值，因此足够指示上述7种情况。
例如：000指示5ms SS burst set的10ms帧的前半帧，001指示5ms SS burst set的10ms帧的后半帧，010指示10ms SS burst set周期，011指示20ms SS burst set周期，100指示40ms SS burst set周期，101指示80ms SS burst set周期，110指示160ms SS burst set周期。这样原来需要4bits的数据指示的信息变为3bits就可以指示。上述取值只是一个举例，可以采用不同的取值。
另外，也可以000指示5ms SS burst set，001指示前半帧，010指示后半帧，011,100,101,110,111指示后面的5种周期，此时用完了3比特取值的8种情况。
本申请另一实施例提出一种指示信息的传输方法，可以降低PBCH的开销，该方法包括：流程与图5类似，包括：
网络设备生成同步信号块SS block，所述SS block包括同步信号SS资源块及物理广播信道PBCH资源块，发送所述SS block；其中，
PBCH资源块中的X比特用于指示SS block的数目和/或时间索引，N-X比特用于指示系统帧号；在不同SS burst set周期下，X的取值不同，N为固定值，X、N均为整数。
相应的，终端设备接收SS block，解调PBCH资源块获取相应的SS block的数目和/或时间索引。
一个例子中，所述SS burst set周期为5ms或10ms时，X＝5；或所述SS burst set周期为20ms以上时，X＝6。
NR当中定义了SS burst set里面的最大的SS block数目为64，因此需要6bits进行指示SS block数目或时间索引。另一个实施例中提出将不同周期上的SS block数目做进一步的细分，利用不同周期上的系统帧号部分比特指示SS block数目或者时间索引。
例如将NR当中的20ms SS burst set周期，40ms SS burst set周期，80ms SS burst set周期和160ms SS burst set周期的中的SS block数目定义为最大为64，需要6bits数据指示SS block数目或者时间索引；10ms周期和5ms周期的波束数目最大为32，需要5bits数据指示SS block数目或者SS block的时间索引。
参考图6，对于20ms及以上的SS burst set周期，其SFN的至少1bit是剩余信息，可以将这1比特借用来指示SS block数目或时间索引，可以为SFN的最后一位，这样6比特中，有1比特位SFN的最后一位，因此实际只使用了5比特，节省了PBCH的开销。
例如，如图6所示，20ms SS burst set周期的SFN最后1bit都为0，因此这1bit是多余的，可以用来指示的SS block数目或者时间索引，这样就可以将用于指示SS block数目或者时间索引的6bits为5bits加上1bit的SFN，1bit的SFN可以是SFN的最后一位；6bits的指示信息中包括1bit的SFN，节省了开销。
又一个实施例中，流程与图5类似，网络设备生成同步信号块SS block，所述SS block包括同步信号SS资源块及物理广播信道PBCH资源块，其中满足以下至少一种情况：PBCH资源块中的X比特用于指示5ms SS burst set的SS block的数目和/或时间索引；PBCH资源块中的X+1比特用于指示10ms SS burst set的SS block的数目和/或时间索引；PBCH资源块中的X+2比特用于指示20ms SS burst set的SS block的数目和/或时间索引；PBCH资源块中的X+3比特用于指示40ms以上SS burst set的SS  block的数目和/或时间索引；
发送所述SS block。
所述X+1比特中的1比特为借用的半帧指示；
所述X+2比特中的1比特为指示系统帧号比特的最后1位，1比特为借用的半帧指示；
所述X+3比特中的2比特为指示系统帧号比特的最后2位，1比特为借用的半帧指示。
一个实施例中X＝3。
终端设备接收SS block，解调PBCH资源块获取相应的SS block的数目和/或时间索引。
NR当中定义了SS burst set里面的最大的SS block数目为64，因此需要6bits进行指示SS block数目，或者需要6bits指示SS block的时间索引。本发明提出将不同周期上的SS block数目做进一步的细分，利用不同周期上的SFN部分数据和半帧指示信息用来指示SS block数目或者SS block的时间索引。例如NR当中的5ms SS burst set周期，其SS block最大数目定义为8，需要3bits进行指示；10ms SS burst set周期，其SS block最大数目定义为16，需要4bits进行指示；20ms SS burst set周期，其SS block最大数目定义为32，需要5bits进行指示；40ms SS burst set周期及其以上，其SS block最大数目定义为64，需要6bits进行指示。
对于10ms及其以上的SS burst set周期，半帧指示是没有使用的，因此可以用来做SS block数目或者SS block的时间索引指示，这样10ms SS burst set周期的SS block数目或者SS block的时间索引的4bits数据指示方式为：3bits的SS block数目或者SS block的时间索引加上1bits的半帧指示。
对于20ms及其以上的SS burst set周期，SFN的最后一位是没有使用的，例如，如图6所示，20ms SS burst set周期的SFN最后1bit都为0，说明SS burst set的位置已经指示了SFN的1bit信息，因此可以用来做SS block数目或者SS block的时间索引指示，这样20ms SS burst set周期的SS block数目或者SS block的时间索引的5bits数据指示方式为：3bits的SS block数目或者SS block的时间索引加上1bits的半帧指示再加上1bits的SFN最后一位。
对于40ms及其以上的SS burst set周期，SFN的最后两位是没有变化的，例如，如图6所示，40ms SS burst set周期的SFN最后2bits都为0，说明SS burst set的位置已经指示了SFN的2bits信息，因此可以用来做SS block数目或者SS block的时间索引指示，这样40ms SS burst set周期的SS block数目或者SS block的时间索引的6bits数据指示方式为：3bits的SS block数目或者SS block的时间索引加上1bits的半帧指示再加上2bits的SFN最后两位。
另一个实施例中，由于SS burst set周期自身携带了部分帧信息，因此，可以结合 SFN，周期，半帧信息中至少一种来实现联合指示，以节约比特数。
该方法流程与图5类似，网络设备生成同步信号块SS block，所述SS block包括同步信号SS资源块及物理广播信道PBCH资源块，发送所述SS block。
其中，至少满足以下一种情况：
PBCH资源块中的X比特用于指示5ms SS burst set周期下的10ms帧的前半帧、后半帧、以及10ms SS burst set周期；
PBCH资源块中的X+1比特用于指示20ms SS burst set；
PBCH资源块中的X+2比特用于指示40ms SS burst set周期；
PBCH资源块中的X+3比特用于指示80ms SS burst set周期；PBCH资源块中的X+4比特用于指示160ms SS burst set周期；
所述X+1比特中的1比特为借用的指示系统帧号比特最后1位；
所述X+2比特中的2比特为借用的指示系统帧号比特最后2位；
所述X+3比特中的3比特为借用的指示系统帧号比特最后3位；
所述X+4比特中的4比特为借用的指示系统帧号比特最后4位。
例如：X＝2。
相应的，终端设备接收所述SS block，解调PBCH资源块获取相应的SS burst set周期。
例如，参考图7及下表1：周期和半帧联合指示(简写为A)有2bit，其中：00分别表示5msSS burst set周期及其5ms SS burst set周期下的前半帧，01分别表示5msSS burst set周期及其5ms SS burst set周期下的后半帧，10表示10ms SS burst set周期。当SS burst set周期大于10ms时，也就是20、40、80、160ms时，用11表示。5ms和10ms下的帧指示通过SFN进行指示，也就是指示当前SS block所在的帧号。取值00、01、11仅是实施例，取值可以采用不同方式。
参考图7，一个帧是10ms，当SS burst set周期为20ms的时候，由于SS burst set每2个帧出现一次，因此，SFN的最后1bit始终为0。所以可以通过SFN的最后一位来区分当周期大于10ms的时候，是20ms还是更大的周期。如果A＝11，SFN最后一位为0，则为20ms的周期。当A＝11，SFN最后一位为1，则为大于20ms的周期，如40、80、160ms周期。
因此，当SS burst set周期为20ms的时候，用周期和半帧联合指示，以及SFN的最后一位来指示SS block的数目或时间索引。
参考图7，一个帧是10ms，当SS burst set周期为40ms的时候，由于SS burst set每4个帧才出现一次，因此，SFN的倒数第2位始终为0。所以可以通过SFN的倒数第2位来区分当周期大于20ms的时候，是40ms还是更大的周期。如果A＝11，SFN最后一位为1，SFN的倒数第2位为0，则为40ms的周期。如果A＝11，SFN最后一 位为1，SFN的倒数第2位为1，则为大于40ms的周期，如80、160ms周期。
因此，当SS burst set周期为40ms的时候，用周期和半帧联合指示，以及SFN的最后2位来指示SS block的数目或时间索引。
参考图7，一个帧是10ms，当SS burst set周期为80ms的时候，由于SS burst set每8个帧才出现一次，因此，SFN的倒数第3位始终为0。所以可以通过SFN的倒数第3位来区分当周期大于40ms的时候，是80ms还是更大的周期。如果A＝11，SFN最后一位为1，SFN的倒数第2位为1，SFN的倒数第3位为0，则为80ms的周期。如果A＝11，SFN最后一位为1，SFN的倒数第2位为1，SFN的倒数第3位为1，则为大于80ms的周期，如160ms周期。
因此，当SS burst set周期为80ms的时候，用周期和半帧联合指示，以及SFN的最后3位来指示SS block的数目或时间索引。
同理，当SS burst set周期为160ms的时候，用周期和半帧联合指示，以及SFN的最后4位来指示SS block的数目或时间索引。
依次类推，可以通过SFN对大于80ms的周期进行指示。具体见下表1以及表2。

表1。注意：X表示由具体当前SS block所在的帧号确定。
当然也可以通过下表2进行指示，也就是通过SFN的取值等于1来指示具体周期，而不是通过取值等于0来指示具体周期，也就是说上表1中SFN的取值0、1可以对调。

表2。注意：X表示由具体当前SS block所在的帧号确定
上述各个实施例中，以上各个实施例方案中，X比特位于PBCH的MIB中，网络设备生成的SS block可以为一个或多个。
PBCH所传输的这些数据比特可以通过SSS和/或PBCH的DMRS(demodulation Reference signal、解调参考信号)，和/或CRC(cyclic Redundancy Check循环冗余校验)码，和/或加扰，和/或RV(redundancy version冗余版本)，和/或循环移位隐式指示，和/或显示指示。
