本公开有益效果如下:
本公开实施例提供的技术方案中,由于第一信息中包括CCE聚合等级、MIMO流数、有效区域、有效时间、接收条件等信息,指示了第二系统信息的发送会采用CCE、MIMO流数的方式。对于类似定位辅助信息的第二系统信息,由于数据量较大,可以通过配置合适的CCE聚合等级,确保第二系统信息合理的覆盖范围,配置合适的MIMO流数,确定适配的传输时延,有效区域、有效时间和接收条件,可以确保第二系统信息在特定的地理空间和时间有效,离开了特定的地理空间和超出有效时间,终端需要重新获取更新的第二系统信息,降低资源开销。由于所述第二系统信息可以采用比第一系统信息更高阶的调制来承载较大的数据量,而接收条件限制了只有当终端处于小区中心信号覆盖比较好时,接收第二系统信息,在小区边缘时,即使接收也可能接收失败,因此处于小区边缘的终端无需接收第二系统信息,进而节省了终端资源。
进一步的,由于通过重复发送系统信息,终端多次接收联合解码,可以实现更好的覆盖。根据实际信道条件,可以调整,调低以节省资源。
进一步的,接收条件包括:RSRP门限、和/或TA(时间提前)门限,由于所述第二系统信息可以采用比第一系统信息更高阶的调制来承载较大的数 据量,因此,只有当终端处于小区中心信号覆盖比较好时,接收所述第二系统信息,在小区边缘时,即使接收也可能接收失败,因此处于小区边缘的终端无需接收所述第二系统信息。

具体实施方式
发明人在发明过程中注意到:
在实施例及说明中将主要以定位系统信息以及其第一信息为例进行说明,定位系统信息与普通系统信息都使用相同的调制编码方式,以及MIMO流数,较为典型,所以这里以定位系统信息以及其第一信息为例;但是,也可以用于其他类似消息及其第一信息,事实上,只要是使用普通的系统信息的调制方式和MIMO流数来发送,很可能会导致更大的开销,甚至导致超大的定位系统信息超过系统信息最大比特数的限制的消息都可以采用,定位系统信息以及其第一信息仅用于教导本领域技术人员具体如何实施本公开,但不意味仅能用于定位系统信息以及其第一信息,实施过程中可以结合实践需要来确定适用的消息。
相关技术中,定位系统信息与普通系统信息都使用相同的调制编码方式,以及MIMO流数。但随着定位技术的发展,定位系统信息变得更加庞大,如 果同样使用普通的系统信息的调制方式和MIMO流数来发送,很可能会导致更大的开销,甚至导致超大的定位系统信息超过系统信息最大比特数的限制。
相比于普通系统信息,定位系统信息具有不同的特点:
普通系统信息需要确保小区内所有终端在任何位置在任何时刻都可以接收到。
定位系统信息,作为定位技术的辅助信息,接收到后,在有效时间内,都可以一直使用,而无需反复接收。
基于上述分析,定位系统信息具有数据量大,但无需终端在任何时刻任何地点都必须接收到的特点,因此,定位系统信息可以配置为更高的调制阶数,和/或更大的MIMO流数。
因此,本公开实施例中将提供系统信息发送及接收方案,下面结合附图对本公开的具体实施方式进行说明。
在说明过程中,将分别从终端与网络侧的实施进行说明,然后还将给出二者配合实施的实例以更好地理解本公开实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施,实际上,当终端与网络侧分开实施时,其也各自解决自身一侧的问题,而二者结合使用时,会获得更好的技术效果。
图1为网络侧系统信息发送方法实施流程示意图,如图所示,可以包括:
步骤101、网络侧向终端发送第一系统信息,其中,所述第一系统信息中包含有第二系统信息组的第一信息,第一信息包括以下信息之一或者其组合:指示第二系统信息的控制信息聚合等级、第二系统信息的MIMO流数、第二系统信息的有效区域、第二系统信息的有效时间、第二系统信息的接收条件信息、指示所述第二系统信息的PDCCH或PDSCH的调制与编码策略的MCS索引、第二系统信息的调制方式、发送第二系统信息的子载波间隔、第二系统信息的发送周期、第二系统信息的加密信息、第二系统信息的加密公钥、第二系统信息发送的重复次数;
步骤102、网络侧根据第一信息向终端发送第二系统信息组。
图2为终端侧系统信息接收方法实施流程示意图,如图所示,可以包括:
步骤201、终端接收网络侧发送的第一系统信息,其中,所述第一系统信息中包含有第二系统信息组的第一信息,第一信息包括以下信息之一或者其组合:指示第二系统信息的控制信息聚合等级、第二系统信息的MIMO流数、第二系统信息的有效区域、第二系统信息的有效时间、第二系统信息的接收条件信息、指示所述第二系统信息的PDCCH或PDSCH的调制与编码策略的MCS索引、第二系统信息的调制方式、发送第二系统信息的子载波间隔、第二系统信息的发送周期、第二系统信息的加密信息、第二系统信息的加密公钥、第二系统信息发送的重复次数;
步骤202、终端根据第一信息接收网络侧发送的第二系统信息组。
具体的,终端接收网络侧发送的第一系统信息(例如,普通系统信息),所述第一系统信息中,包含有第二系统信息组的第一信息,所述第二组系统信息中包含至少1个第二系统信息(例如,定位系统信息)。即,也可以包含若干个第二系统信息,组成1个第二系统信息组。
控制信息聚合等级是指,第二系统信息的PDCCH的聚合等级,即CCE聚合等级。
所述第一信息,可以是第二组系统信息中的部分系统信息共用,也可以单独应用于第二组系统信息中的某一个系统信息,具体实践时,第一信息可能会被命名为配置信息、或者调度信息,或者其他名称,但毫无疑问,不管怎么命名都不影响本方案的实施。
具体的,网络侧发送至少一组参数。例如,如果网络侧发送一个调制阶数,则应用于第二系统信息;如果网络侧发送两个调制阶数,则分别应用于第一系统信息和第二系统信息。由于定位系统信息数据量大的特点,可以采用与第一系统信息不同的调制阶数、MIMO流数等,因此可以为第二系统信息配置专门的参数,第一系统信息可以同时也配置参数,或者采用默认的参 数。
系统信息的第一信息可以是以下信息之一或者其组合:
1、MCS索引(MCS index),即MCS标识。MCS(Modulation and Coding Scheme,调制与编码策略)用于指示所述第二系统信息的物理下行控制信道(Physical downlink control channel,PDCCH)或物理下行共享信道(Physical downlink shared channel,PDSCH)的调制与编码策略。例如MCS-1,MCS-5等,不同的MCS代表不同的调制与编码策略。
2、调制方式,即,所述系统信息的调制方式,可以是PDCCH和或PDSCH。例如MCS-1,MCS-3等,例如,二相相移键控(Binary Phase Shift Keying,BPSK)、正交相移键控(Quadrature Phase Shift Keying,QPSK)、16正交幅度调制(Quadrature Amplitude Modulation,QAM)、64QAM、256QAM、1024QAM等。
3、控制信道单元(Control Channel Element,CCE)聚合等级;所述CCE聚合等级是指系统信息的PDCCH聚合等级。CCE聚合等级会影响系统信息的覆盖,可以根据目标覆盖范围,调整所述聚合等级。对于第二系统信息,由于数据量较大,可以通过配置合适的CCE聚合等级,降低资源开销。
4、MIMO流数;即,所述系统信息的MIMO流数。
5、子载波间隔。
6、发送周期;所述周期是指系统信息的发送周期。
7、加密信息;即,指示系统信息是否加密,以及用何种加密方式或何种加密算法。
8、加密公钥;所述公钥用于终端解码第二系统信息。
9、重复次数;即,所述的系统信息重复发送了几次。通过重复发送系统信息,终端多次接收联合解码,可以实现更好的覆盖。根据实际信道条件,可以调整,调低以节省资源。
10、有效区域;即,所述系统信息在哪些区域内有效,所述有效区域, 可以是以下至少之一:小区标识,或者跟踪区(tracking area,TA)标识,或者地理区域标识,或者海拔或高度标识。确保第二系统信息(即,定位系统信息)在特定的地理空间有效,离开了所述地理空间,终端需要重新获取更新的第二系统信息。
11、有效时间;即,所述系统信息在所述有效时间内都是有效的。
12、接收条件信息,所述“接收条件信息”是指当终端满足所述条件时,才可以接收所述第二系统信息,不满足时,无需接收第二系统信息。所述接收条件包括以下至少之一:参考信号接收功率(Reference Signal Received Power,RSRP)门限、时间提前(Timing Advance,TA)门限。如果所述接收条件是RSRP门限,则只有终端测量的RSRP超过所述门限时,终端才可以接收第二系统信息。如果所述接收条件是TA,则只有终端的TA小于所述TA门限时,终端才可以接收所述第二系统信息。由于所述第二系统信息可以采用比第一系统信息更高阶的调制来承载较大的数据量,因此,只有当终端处于小区中心信号覆盖比较好时,接收所述第二系统信息,在小区边缘时,即使接收也可能接收失败,因此处于小区边缘的终端无需接收所述第二系统信息。也即,实施中,终端接收网络侧发送的第一系统信息后,还可以进一步包括:
根据第一信息中的第二系统信息的接收条件信息,确定是否接收第二系统信息。
实施中,在第二系统信息的接收条件信息包括:RSRP门限和/或TA门限时,还可以进一步包括:
终端测量的RSRP超过所述RSRP门限时,终端接收第二系统信息;和/或,
终端的TA小于所述TA门限时,终端接收所述第二系统信息。
上述1-9项信息,终端接收到后,终端可以采用所述的配置来接收所述系统信息。
上述10、11信息,终端接收到后,终端可以用来判断,当前储存的第二系统信息是否有效,是否需要重新接收第二系统信息。即,只要终端储存的第二系统信息仍然有效,终端无需重复接收。
例如,第二系统信息组中包含A/B/C这三个第二系统信息。所述第一系统信息中携带的第二系统信息的第一信息如下:
系统信息A的调制阶数是BPSK,MIMO流数是2。
系统信息B的调制阶数是16QAM,MIMO流数是4流。
系统信息C的调制阶数是64QAM,MIMO流数是8流。
终端收到后,用所述的第一信息,分别接收系统信息A/B/C。
实施中,终端接收网络侧发送的第一系统信息前,进一步包括:
终端向网络侧发送系统信息请求消息,或终端辅助信息。
相应的,网络侧向终端发送第一系统信息前,进一步包括:

终端请求的发送第二系统信息的子载波间隔;
终端请求的发送第二系统信息的发送周期;
终端请求的第二系统信息的加密方式;
终端请求的发送第二系统信息的发送重复次数。
实施中,还可以进一步包括:
网络侧根据系统信息请求消息,或终端辅助信息配置第一信息。
具体实施中,根据系统信息请求消息,或终端辅助信息配置第一信息, 包括:
配置发送终端请求的系统信息;
在多个终端发送的多个MCS中,配置MCS为最低的MCS;

在多个终端发送的多个调制阶数中,配置调制阶数为最低的调制阶数;
配置为终端请求的发送第二系统信息的子载波间隔;
配置为终端请求的发送第二系统信息的发送周期;
配置为终端请求的第二系统信息的加密方式;
配置为终端请求的发送第二系统信息的发送重复次数。
具体的,终端可以向网络侧系统信息请求消息,或者称为终端辅助信息,所述系统信息请求消息用于请求例如,第二系统信息组中的一个或多个第二系统信息。或者所述终端辅助信息,用于辅助网络侧发送系统信息。
相应的,网络侧根据系统信息请求消息,或终端辅助信息配置第一信息。
所述系统信息请求消息包括以下信息之一或者其组合:
终端请求指定的系统信息;
MCS请求;终端向网络侧请求特定的MCS,或者发送最大MCS。请求特定MCS是指请求网络侧已特定的MCS来调制PDCCH或PDSCH;发送最大MCS,是指终端向网络侧发送终端在当前信道条件下最大的MCS。网络侧收到多个终端发送的MCS请求,网络可以从中选取最低的MCS来调制PDCCH或PDSCH,确保尽量多的终端可以正确解码。
CCE聚合等级请求;用于辅助网络侧选用合适的CCE聚合等级发送第二系统信息,终端发送的可以是自己倾向的CCE聚合等级,或者确保终端正确解码的最低CCE聚合等级要求;CCE聚合等级越高,PDCCH的覆盖越好,信号好的终端会请求较低的CCE,信号差的终端会请求较高的CCE,网络侧收到后,确定采用特定的CCE聚合等级发送第二系统信息。一种可能是网络 侧为确保信号好和坏的终端都能接收到,会采用较高的CCE聚合等级。
调制阶数请求;用于终端请求网络侧以特定调制阶数发送系统信息;所述调制阶数可以是终端期望的调制阶数,也可以是最大调制阶数,即超过该最大调制阶数,终端当前信道条件下无法正确解码。网络侧收到多个终端的所述请求后,可以选取最低的调制阶数来发送,确保所有终端均能收到,或者,网络侧选取与所述调制阶数相对应的MCS。调制阶数越高,信道好的终端可以正确解调,信道差的终端无法正确解调。请求网络侧以特定的MIMO流数发送系统信息;
请求以特定的子载波间隔发送系统信息;
请求以特定的周期发送系统信息;
请求以特定的加密方式发送系统信息;
请求系统信息重复特定次数。
实施中,向网络侧发送系统信息请求消息,或终端辅助信息后,进一步包括:
接收网络侧发送的第二系统信息组的第一信息,在未接收到第一系统信息时,进入连接态,向网络侧发送系统信息请求消息,或终端辅助信息。
具体的,当终端发送了所述系统信息请求消息后,终端要去接收网络侧下发的第二系统信息组的第一信息。以此来获知请求的系统信息是否开始广播,如果没有广播,终端进入连接态,系统信息请求消息。
例如:MCS与调制阶数的关系可以如下:
1个MCS对应一组调制结束、码率。
终端可以直接请求特定的MCS,或者请求特定的调制阶数。
如果请求的是特定调制阶数,代表与该调制阶数相对应的一组MCS都可适用于该终端,例如调制阶数4,对应的MCS 10~16。
