但是,相比于常规终端,智能可穿戴设备、工业传感器等具有更小带宽能力、更少天线数量等低能力的终端设备,在收到SSB后,由于CORESET0的带宽配置超出了这类低能力终端设备的带宽范围,或者CORESET0与SSB的复用方式不被这类低能力终端设备所支持等原因,导致这类低能力终端设备无法进 一步接收CORESET0,从而无法接入网络,或者这类低能力终端设备可以接入网络,但是无法与常规终端设备在网络中共存。

具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
另外,在本申请实施例中,“可选地”或者“示例性地”等词用于表示作例子、例证或说明。本申请实施例中的涉及的“第一”、“第二”仅是用于区分不同的概念、消息等,并不用于顺序的限定。
在本申请实施例中,将例如智能可穿戴设备、工业传感器等带宽能力小于常规意义上的终端,比如最大带宽支持频率范围1(Frequency range 1,FR1)内10MHz、20MHz或40MHz,频率范围2(即FR2)内50MHz或100MHz,且无法支持CORESET0的所有配置的终端统称为第一类型终端,将常规意义上的终端,例如Release 15和Release 16中定义的终端,如手机等,统称为第二类型终端。
在NR网络中,第二类型终端根据MIB中的SIB1对应的PDCCH配置信令获取对应CORESET0配置信息和搜索空间0配置信息。相关技术中定义了一组表格,部分内容如表1所示,用于对CORESET0配置信息进行指示,具体的指示方式为:4bit信息用于指示索引(index)0~15,每个索引指示4个内容,分别为SSB与CORESET0之间的复用图样,CORESET0的资源块(Resource Block,RB)数量
Figure PCTCN2021072689-appb-000001
CORESET0的符号数
Figure PCTCN2021072689-appb-000002
CORESET0与SSB之间的频域偏移offset,其中,如图1所示,复用图样为1表示CORESET0与SSB在时域上占用不同的符号,频域上CORESET0包含SSB,复用图样为2表示CORESET0与SSB在频域上占用不同的资源且在时域上SSB占用CORESET0前面的符号,复用图样为3表示CORESET0与SSB在频域上占用不同的资源且在时域上占用相同的符号。搜索空间0配置信息也用于指示索引0~15,该索引 对应的配置信息可以用于确定搜索空间0的时域位置,同时也是CORESET0时域位置。
示例性地,表1的内容用于指示{同步信号/物理广播信道块,PDCCH}子载波间隔组合为{15kHz,15kHz}且最小信道带宽(minimum channel bandwidth)为5MHz或10MHz情况。
表1
Figure PCTCN2021072689-appb-000003
Figure PCTCN2021072689-appb-000004
但是,第一类型终端的带宽能力并不能完全支持表1中所示的CORESET0配置,例如,假设第一类型终端的带宽能力为10MHz,当CORESET0配置为96个RB时,所占带宽为17.28MHz,则此时第一类型终端无法支持该CORESET0。在NR系统中,为了兼容第一类型终端的接入,网络侧在配置初始接入相关信号信道时,需要为CORESET0配置更低的带宽,例如24或48个RB,这样索引12~14的CORESET0配置将被限制,从而影响第二类型终端接入网络的性能。
基于上述场景存在的缺陷,图2提供了一种配置信息确定方法的流程图,该方法可以应用于第一类型终端,如图2所示,该方法包括:
S201、第一类型终端根据基站发送的MIB中的SIB1对应的PDCCH配置信令确定第一类型终端对应的第一CORESET0的配置信息。
其中,上述MIB中SIB1对应的PDCCH配置信令对应的CORESET0为第二类型终端对应的第二CORESET0。
可选地,该第二类型终端与上述第一类型终端在带宽、成本、复杂度、处理能力、能耗、以及设备大小中有至少一项不同。
若第一类型终端和第二类型终端接收到相同的SSB时,就会接收到相同的4比特CORESET0指示信息,该4比特信息指示一个索引值。第一类型终端和第二类型终端可以根据获取到的同一个索引值,分别获取相应的CORESET0配置信息。
示例性地,当上述第二类型终端对应的第二CORESET0对于第一类型终端适用,即表示第二CORESET0和第一CORESET0相同;反之,若第二CORESET0对于第一类型终端不适用,则第一类型终端根据主信息块MIB中的SIB1对应 的PDCCH配置信令获取第一CORESET0配置信息。
通过上述方式,无论基站发送的索引对应的CORESET0配置是否超出第一类型终端的接入能力,第一类型终端都可以获取第一CORESET0的配置信息。这样,在第一类型终端与第二类型终端共存于网络中时,第一类型终端仍然可以根据配置信息正确的接入网络,从而实现在不影响第二类型终端接入网络性能的前提下,也保证第一类型终端可以根据配置信息顺利接入网络。
在本申请实施例中,第一CORESET0的配置信息与第二CORESET0的配置信息类似,也包括SSB与CORESET0之间的位置关系,CORESET0的资源块(Resource Block,RB)数量
Figure PCTCN2021072689-appb-000005
CORESET0的符号数
Figure PCTCN2021072689-appb-000006
CORESET0与SSB之间的频域偏移offset四方面的内容。
在一种示例中,当载频的频率范围为FR1,即410MHz~7125MHz时,上述第一CORESET0多个索引值对应的配置信息可以如表2所示。
表2
Figure PCTCN2021072689-appb-000007
Figure PCTCN2021072689-appb-000008
通过表1和表2可以看出,当基站发送的索引为0~11时,第一类型终端和第二类型终端获取相同的配置信息,即获取相同的CORESET0,而当第一类型终端由于带宽的限制(例如,10MHz)无法获取第二类型终端索引为12~14对应的CORESET0的配置信息时,通过本申请实施例提供的方案,第一类型终端可以基于第一CORESET0配置信息(也即表2)正确获取与索引对应的CORESET0的配置信息,从而在网络中与第二类型终端共存。
在一实施例中,上述表2的内容仅是针对{SSB,PDCCH}子载波间隔组合为{15kHz,15kHz}时,对第一CORESET0配置信息的示例性呈现,并不限定第一CORESET0的具体配置信息。
示例性地,假设上述表2中索引12~14的配置信息如表3所示:
表3
Figure PCTCN2021072689-appb-000009
Figure PCTCN2021072689-appb-000010
即当第一CORESET0的RB数量为48RB时,在第一CORESET0所有RB数量配置情形(24、48、96)中,既可以满足第一类型终端的接入条件,又可以相对24RB提供更大的CORESET0带宽,而且3个符号数的配置相比于1或2个符号数也可以提供更多的时域资源。另外,2和3个符号数的两种不同配置可以提供一定的时域配置灵活性,频域偏移提供12、14、16三种不同的配置,可以提供一定的配置灵活性,并且第一CORESET0的频域位置配置满足第一CORESET0和SSB频率中心位置尽可能对齐的原则。图3提供了表3示例中,SSB与第一CORESET0、第二CORESET0的两种可能的相对位置关系。
可选地,上述表2中索引12~14的配置信息也可以如表4和表5所示:
表4
Figure PCTCN2021072689-appb-000011
表5
Figure PCTCN2021072689-appb-000012
其中,表4、表5中参数k SSB表示SSB的子载波0与公共资源块(common resource block,CRB)
Figure PCTCN2021072689-appb-000013
的子载波0在频域上的载波偏移,
Figure PCTCN2021072689-appb-000014
表示在频域上和SSB有重叠的所有CRB中频域位置最低的一个CRB。
在表4和表5所提供的第一CORESET0复用图样为2和3的配置的情况下,SSB和第一CORESET0频分复用,可以使得第一CORESET0占用更少的时域资源,且可以有效减少同步时延。复用图样2和3的配置既提供了第一CORESET0时域位置的灵活性,且复用图样3也可以为物理下行共享信道(Physical Downlink Shared Channel,PDSCH)预留更多的资源;SSB与第一CORESET0之间频域偏移的正、负两种配置,也提供了第一CORESET0频域位置的灵活性。图4示出了表4、表5示例中,SSB与第一CORESET0、第二CORESET0的几种可能的相对位置关系。
在一种示例中,当载频的频率范围为FR2,即24250MHz~52600MHz,且{SSB,PDCCH}子载波间隔组合为{120kHz,60kHz}时,第一CORESET0的配置信息可以如表6所示。
表6
Figure PCTCN2021072689-appb-000015
Figure PCTCN2021072689-appb-000016
表6中对第一CORESET0和第二CORESET0的不同配置信息进行了对比,当基站发送的索引为0~9时,第一类型终端与第二类型终端可以获取相同的配置信息,当基站发送的索引为10~11时,对于第一类型终端无法获取的索引10、11对应的已有的(或第二CORESET0配置表格中)配置信息,第一类型终端可 以基于表6获取正确的与索引10、11对应的CORESET0的配置信息,以保证后续步骤的顺利进行,第二类型终端可以基于自身存储的第二CORESET0配置表格,也即表6中的标注的配置信息获取与索引10、11对应的CORESET0的配置信息,这样可以实现第一类型终端与第二类型终端在网络中的共存。
在一实施例中,上述表6中第一CORESET0的配置信息也仅是示例性的呈现,并不限定第一CORESET0的配置信息的具体内容。
示例性地,假设上述表6中索引10~11的配置信息如表7所示:
表7
Figure PCTCN2021072689-appb-000017
在表7的示例中,SSB与第一CORESET0为复用图样1时,带宽满足96RB的第一CORESET0配置,可以提供更大带宽的第一CORESET0,而且1和2两种符号数的配置可以实现配置的灵活性。另外,28RB的频域偏移配置可以使得第一CORESET0的频域位置配置满足第一CORESET0和SSB频率中心位置尽可能对齐的原则。
图5提供了表7示例中,SSB与第一CORESET0、第二CORESET0的两种可能的相对位置关系。
可选地,上述表6中索引10~11的配置信息也可以如表8、表9、表10所示:
表8

Figure PCTCN2021072689-appb-000019
表9
Figure PCTCN2021072689-appb-000020
表10
Figure PCTCN2021072689-appb-000021
在上表8~10提供的第一CORESET0与SSB的复用图样为2或3的配置时,可以占用更少的时域资源,且这样的配置可以使得同步的时延更低,另外,第一CORESET0与SSB的频域偏移配置也可以保证第一CORESET0与第二CORESET0互不影响。图6提供了表8~10示例中,SSB与第一CORESET0、第二CORESET0的几种可能的相对位置关系。
在一种示例中,当载频的频率范围为FR2,且{SSB,PDCCH}子载波间隔组合为{120kHz,120kHz}时,第一CORESET0的配置信息可以如表11所示。
表11
Figure PCTCN2021072689-appb-000022
Figure PCTCN2021072689-appb-000023
Figure PCTCN2021072689-appb-000024
表11中对第一CORESET0和第二CORESET0的不同配置信息进行了对比,当基站发送的索引为6~7时,对于第一类型终端由于带宽限制(例如,100MHz)无法获取索引6、7对应的已有的(或第二CORESET0)配置信息,第一类型终端可以基于表11获取正确的与索引6、7对应的CORESET0的配置信息,以保证顺利接入网络,第二类型终端可以基于自身存储的第二CORESET0配置表格,也即表11中的标注的配置信息获取与索引6、7对应的CORESET0的配置信息,这样当基站发送索引时,第一类型终端和第二类型终端均可以获取与索引对应的配置信息。
在一实施例中,上述表11中第一CORESET0的配置信息也仅是示例性的呈现,并不限定第一CORESET0的配置信息的具体内容。
示例性地,假设上述表11中索引6~7的配置信息如表12所示:
表12
Figure PCTCN2021072689-appb-000025
在表12的示例中,SSB与第一CORESET0为复用图样1,带宽满足48RB的第一CORESET0的配置,因而48RB的配置相对24RB可以提供更大带宽的第一CORESET0,而且1和2两种符号数的配置,实现了配置的灵活性。另外,14RB的频域偏移配置可以使得第一CORESET0的频域位置配置满足第一CORESET0和SSB频率中心位置尽可能对齐的原则。图7提供了表12示例中,SSB与第一CORESET0、第二CORESET0的两种可能的相对位置关系。
可选地,上述表11中索引6~7的配置信息也可以如表13、表14、表15所示:
表13
Figure PCTCN2021072689-appb-000026
表14
Figure PCTCN2021072689-appb-000027
表15
Figure PCTCN2021072689-appb-000028
在表13~15提供的示例中,第一CORESET0与SSB为复用图样2或3的配置,这样可以占用更少的时域资源,且该配置可以使得同步的时延更低,同时第一CORESET0与SSB的频域偏移配置可以保证第一CORESET0和第二CORESET0互不影响。图8提供了表13~15示例中,SSB与第一CORESET0、第二CORESET0的几种可能的相对位置关系。
另外,在CORESET0中定义有终端检测PDCCH的时频资源块,PDCCH检测的时域位置(也称为监测时机(Monitoring Occasion,MO)),该时域位置由搜索空间配置信息指示。Type0PDCCH的搜索空间,又称为搜索空间0(Search Space Zero,SS0),可以通过MIB中4bit指示域指示。如表16所示,为SSB与CORESET0复用图样为1时,一种搜索空间0的指示示意表。
表16
Figure PCTCN2021072689-appb-000029
Figure PCTCN2021072689-appb-000030
如表16所示,MIB中4bit指示域用于指示索引0~15,不同索引分别对应于一种搜索空间配置,每种配置包括以下四方面的内容,分别为计算监测时机所在时隙(slot)索引时用到的参数O和M,每个时隙内搜索空间的个数P,以及起始符号索引S,其中,参数O和M为本领域公知的参数,用于控制搜索空间所使用的时隙。
第二类型终端可以按照4bit信息的指示获取搜索空间0的配置信息,当第一CORESET0和第二CORESET0与SSB之间均为时域占用不同符号且频域上包含SSB的关系时,第一类型终端可以根据第二类型终端的搜索空间确定第一类型终端搜索空间的时域位置,也可以根据SSB的位置确定第一类型终端搜索空间时域位置。
可选地,第一类型终端可以根据SSB的位置,或者根据SSB的位置以及一个偏移量,确定第一类型终端搜索空间时域位置。第一类型终端搜索空间可以与SSB在时域上相邻,例如,可以在SSB的前面,也可以在SSB后面。该偏移量可以是一个时隙级别的偏移量,或者是一个符号级别的偏移量,且该偏移量可以为正也可以为负。
可选地,第一类型终端可以根据第二类型终端的搜索空间配置信息,确定 第二类型终端搜索空间的时域位置,并根据第二类型终端搜索空间的时域位置,或者第二类型终端搜索空间的时域位置以及偏移量,确定第一类型终端搜索空间的时域位置。第一类型终端的搜索空间可以与第二类型终端的搜索空间紧挨,例如,可以在第二类型终端搜索空间的前面或者后面。该偏移量可以为一个时隙级别的偏移量,或者一个符号级别的偏移量,并且可以为正也可以为负。
其中,在上述方式中,一个时隙级别的偏移可以理解为一个SSB周期内,索引为0的SSB对应的第二类型终端搜索空间所在的时隙和第一类型终端搜索空间所在的时隙之间的偏移。
示例性地,当偏移量为时隙级别的偏移量时,对于索引为i的SSB,第二类型终端的搜索空间所在的时隙为起始标号
Figure PCTCN2021072689-appb-000031
的两个连续时隙,其中,
Figure PCTCN2021072689-appb-000032
表示对于子载波间隔配置u,每个帧中包含的时隙的数量,u的取值可以为0、1、2、3,分别对应15KHz、30KHz、60KHz、120KHz的子载波间隔。第一类型终端可以根据参数O和M,以及一个周期内SSB的最大数量L max,计算得到第二类型终端的所有搜索空间需要占用的时隙资源,进而根据计算结果,进行一个时隙级别的偏移(offset_slot),以确定第一类型终端搜索空间的时域位置。
在一实施例中,该一个时隙级别的偏移还需要至少满足以下条件:
Figure PCTCN2021072689-appb-000033
在满足上述条件的基础上,第一类型终端搜索空间所占的时隙可以紧挨第二类型终端搜索空间所占的时隙,即一个SSB周期内,第一个SSB对应的第一类型终端搜索空间的起始时隙紧挨最后一个SSB对应的第二类型终端搜索空间 所占的最后一个时隙。这样的设计不仅不影响第二类型终端的PDSCH配置灵活性,而且可以尽早完成第一类型终端的同步。
除了上述方法以外,第一类型终端搜索空间所占的时隙也可以从未被第二类型终端使用的时隙中的任意时隙开始。
另外,除了起始时隙,其余的第一类型终端搜索空间配置信息参数M L、每个时隙内第一类型终端搜索空间的个数P L和第一类型终端起始符号索引S L可以和对应索引中第二类型终端的配置信息相同或者不同。其中,P L的取值可以为1或2,M L的取值可以为1或1/2,当M L的值为1时,S L的取值可以为0~13中的任意整数值,例如,0、1、2、7,当M L的值为1/2时,S L的取值可以为{0,若i为偶数;
Figure PCTCN2021072689-appb-000034
若i为奇数}或{0,若i为偶数;7,若i为奇数}等,i为SSB索引。
示例性地,当一个周期内SSB的最大数量L max的值为4,参数O为0,M为1时,周期内四个SSB对应的第二类型终端搜索空间所占时隙(slot)为slot0到slot 4,此时第一类型终端可以从slot 5开始作为索引为0的SSB对应的第一类型终端搜索空间的起始时隙,即此时offset_slot=5。令其他参数M L=1,P L=1,则对应的情形如图9所示。
可选地,当参数M L=1/2,P L=2,S L为{0,若i为偶数;7,若i为奇数}或{0,若i为偶数;
Figure PCTCN2021072689-appb-000035
若i为奇数}时,则对应的情形如图10或11所示。
示例性地,当偏移量为符号级别的偏移量时,第一类型终端的搜索空间和第二类型终端的搜索空间所在的时隙会存在重叠,若定义第一类型终端搜索空间所在的时隙为起始标号
Figure PCTCN2021072689-appb-000036
的两个连续时隙,即第一类型终端获取和第二类型终端相同的参数M,则决定搜索空间起始时隙的参数O L与第二类型终端参数O可能不同,也可能相同。这种情况取决于第二类型 终端参数O的具体取值和SSB的时域位置,即O L的取值要保证第一类型终端的搜素空间不会与SSB发生重叠,进而通过起始符号索引S L与S的不同实现符号级别的偏移,即第一类型终端的搜索空间起始符号索引S L与第二类型终端的搜索空间起始符号索引S之间会存在一个偏移offset_symbol,该偏移满足公式:S L=S+offset_symbol,且该偏移需要满足条件:
Figure PCTCN2021072689-appb-000037
其中
Figure PCTCN2021072689-appb-000038
为第二CORESET0所占符号的个数,即该偏移要保证同一个时隙内的第一类型终端和第二类型终端的搜索空间不会重叠。当然,同一个时隙中的第一类型终端的搜索空间可以与第二类型终端的搜索空间紧挨,也可以占用第二类型终端搜索空间未占用的任意符号。
示例性地,假设一个周期内SSB的最大数量L max的值为4,参数O和M的值分别为0、1,第二类型终端搜索空间起始符号索引S=0,图12示出了O L=2,
Figure PCTCN2021072689-appb-000039
的情形,这样可以避免第一CORESET0与SSB以及第二CORESET0的重叠,即此种情况下,同一个时隙内的第一类型终端和第二类型终端的搜索空间为紧挨的方式。
可选地,当L max的值为4,参数O和M的值分别为2、1,起始符号索引S=0,此时,O L的取值与参数O的取值相同,如图13所示,为O L=O=2,
Figure PCTCN2021072689-appb-000040
的情形。
另外,对于同一个SSB的第一CORESET0可能在第二CORESET0之前的情形,如图14所示,为一个周期内SSB的最大数量为4,参数O=2,M=1,S=0,O L=O-1,S L=S+offset_symbol=0+offset_symbol=12的情形。
在另一种示例中,当第一CORESET0与SSB在时域上占用不同符号且频域上包含SSB时,同时第二CORESET0与SSB在频域上占用不同的资源时,第二CORESET0具有与SSB固定的相对位置,此时MIB中承载的用于指示第二 类型终端搜索空间0配置信息的4bit指示域未被使用,将该指示域用于指示第一类型终端搜索空间0配置信息。第一类型终端根据搜索空间0配置信息确定第一CORESET0的位置信息,所述搜索空间0配置信息指示第一CORESET0时域位置配置参数,例如,O L、M L、P L、S L,以使得第一类型终端获取自身的CORESET0时域位置,具体的指示信息可通过表格的方式,指示4比特对应的每个索引的具体配置,所述表格可以和第二类型终端的CORESET0指示信息示意表相同,也可以设计新的表格。
在一种示例中,当第一CORESET0与SSB在频域上占用不同的资源时,第一类型终端的搜索空间与SSB具有固定的相对位置,无需信令指示。
另外,第一类型终端根据第二CORESET0以及PDCCH配置信令确定第一CORESET0的时域位置可以通过以下可选的方式实现:
第一种方式,当PDCCH配置信令指示第二CORESET0与SSB的关系为在时域上占用不同的符号,且频域上第二CORESET0包含SSB时,则第一CORESET0与SSB的关系为在时域上占用不同的符号,且频域上第一CORESET0包含SSB;
第二种方式,当PDCCH配置信令指示第二CORESET0与SSB的关系为频域上占用不同的资源时,则第一CORESET0与SSB的关系为频域上占用不同的资源。
在一种示例中,第一类型终端按照MIB内的第一接入指示信息确定当前小区是否支持第一类型终端的接入。该第一接入指示信息可以为以下情况之一:
第一接入指示信息为MIB中已有的小区禁止指示cellBarred,在这种情况下,第一类型终端和第二类型终端都按照小区禁止指示来确定是否可以接入当前小区;
或者,第一接入指示信息占用MIB中预留的1bit信息,用于指示第一类型终端是否可以接入当前小区,小区禁止指示用于指示第二类型终端是否可以接入当前小区。例如,第一接入指示信息为“1”表示允许第一类型终端接入,为“0”表示禁止第一类型终端接入,或者,第一接入指示信息为“0”表示允许第一类型终端接入,为“1”表示禁止第一类型终端接入。
在一种示例中,第一类型终端按照下行控制信息格式1_0(Downlink Control Information format 1_0,DCI format 1_0)内的接入指示信息域确定当前小区是否支持第一类型终端的接入,MIB内的小区禁止指示(cellBarred)只用于指示第二类型终端是否被允许接入当前小区,即第一类型终端可以忽略MIB中的小区禁止指示cellBarred,只按照DCI format 1_0内的接入指示信息域确定是否可以接入当前小区。
或者,第一类型终端按照当前小区是否配置了第一CORESET0确定当前小区是否持第一类型终端的接入;
其中,接入指示信息对应下行控制信息在第一CORESET0中传输,并且下行控制信息被系统信息-无线网络临时标识(System Information-Radio Network Tempory Identity,SI-RNTI)加扰。
在一种示例中,接入指示信息域用于指示当前小区是否支持第一类型终端的接入。例如,当网络中配置为第一CORESET0和第二CORESET0同时存在时,第一类型终端如果可以按照MIB中的PDCCH配置信令获取第一CORESET0,则第一类型终端认为该小区为可接入的小区;如果网络中只配置了CORESET0,且该CORESET0不适用于第一类型终端,则第一类型终端认为该小区为不可接入的小区。
在一种示例中,SI-RNTI加扰的DCI format 1_0内包含第一类型终端和第二 类型终端的接入指示信息。SI-RNTI加扰的DCI format 1_0中的信息域包含如下至少之一:
频域资源分配(Frequency domain resource assignment);
时域资源分配(Time domain resource assignment);
虚拟资源块到物理资源块映射方式(VRB-to-PRB mapping);
调制编码方案(Modulation and coding scheme);
冗余版本(Redundancy version);
系统消息指示(System information indicator);
预留比特(Reserve bits)。
其中预留比特占用15bit,如果网络中只配置了CORESET0,且该CORESET0可以同时适用于第一类型终端和第二类型终端,则接入指示信息对应的DCI format 1_0包含在该CORESET0内,并且同时适用于第一类型终端和第二类型终端的SI-RNTI加扰的DCI format 1_0所包含的信息为如下至少之一:
频域资源分配(Frequency domain resource assignment);
时域资源分配(Time domain resource assignment);
虚拟资源块到物理资源块映射方式(VRB-to-PRB mapping);
调制编码方案(Modulation and coding scheme);
冗余版本(Redundancy version);
系统消息指示(System information indicator);
第一类型终端接入指示信息;
预留比特(Reserve bits)。
第一类型终端和第二类型终端均可以接收SI-RNTI加扰的DCI format 1_0,但其中的第一类型终端接入指示只对第一类型终端有效,第二类型终端不解读 该信息域。第一类型终端接入指示信息占用原本预留的比特,可以为1bit的信令开销,例如,“1”代表支持第一类终端的接入,“0”代表不支持第一类终端的接入;或者“0”代表支持第一类终端的接入,“1”代表不支持第一类终端的接入。当然,也可以利用该接入指示信息域是否存在来指示是否支持第一类终端的接入,例如,存在则代表支持第一类终端的接入,不存在则代表不支持第一类终端的接入,此时预留比特占用14bit。接入指示信息域也可以占用2bit的信令开销,以适用于第一类型终端进一步划分了终端类型的情况,具体的指示方式包括如下情况:例如“11”代表支持所有第一类型终端的接入,“01”代表支持第一类型终端中的类型A终端的接入,“10”代表支持第一类型终端中的类型B终端的接入,“00”代表不支持任何第一类型终端的接入,此时预留比特占用13bit。上述类型A和类型B表示第一类型终端中进一步根据终端能力划分的不同类型的终端。
在一种示例中,SI-RNTI加扰的DCI format 1_0内包含第一类型终端的接入指示信息。该接入指示信息对应的DCI format 1_0包含在第一CORESET0或第二CORESET0内,包含接入指示信息的DCI format 1_0包含的信息为如下至少之一:
频域资源分配(Frequency domain resource assignment);
时域资源分配(Time domain resource assignment);
虚拟资源块到物理资源块映射方式(VRB-to-PRB mapping);
调制编码方案(Modulation and coding scheme);
冗余版本(Redundancy version);
系统消息指示(System information indicator);
第一类型终端接入指示信息;
预留比特(Reserve bits)。
其中第一类型终端接入指示信息占用原本预留的比特,可以为1bit的信令开销,例如,“1”代表支持第一类终端的接入,“0”代表不支持第一类终端的接入;或者“0”代表支持第一类终端的接入,“1”代表不支持第一类终端的接入。在一实施例中,也可以利用该接入指示信息域(包括接入指示信息)是否存在来指示是否支持第一类终端的接入,例如,存在则代表支持第一类终端的接入,不存在则代表不支持第一类终端的接入,此时预留比特占用14bit。接入指示信息域也可以占用2bit的信令开销,以适用于第一类型终端进一步划分了终端类型的情况,具体的指示方式包括如下情况:例如,“11”代表支持所有第一类型终端的接入,“01”代表支持第一类型终端中的类型A终端的接入,“10”代表支持第一类型终端中的类型B终端的接入,“00”代表不支持任何第一类型终端的接入,此时预留比特占用13bit。上述类型A和类型B表示第一类型终端中进一步根据终端能力划分的不同类型的终端。
在一种示例中,第一类型终端按照MIB内的第一接入指示信息确定当前小区是否支持第一类型终端的接入,该第一接入指示信息为MIB中已有的小区禁止指示cellBarred。此时,SI-RNTI加扰的DCI format 1_0内也包含第一类型终端接入指示信息。如果MIB内第一接入指示信息禁止第一类型终端接入当前小区,则第一类型终端不接入当前小区,如果第一接入指示信息允许第一类型终端接入当前小区,则第一类型终端按照DCI format 1_0内的第一类型终端接入指示信息确定是否接入当前小区。
在一种示例中,第一类型终端按照DCI format 1_0内的第一短信息域(包括第一短信息)确定第一类型终端对应的系统消息的情况。
其中,第一短信息对应下行控制信息在第一CORESET0中传输,并且下行 控制信息被寻呼-无线网络临时标识(Paging-Radio Network Tempory Identity,P-RNTI)加扰;
或者,第一短信息对应下行控制信息在第一CORESET0中传输,下行控制信息被P-RNTI加扰,并且第一短信息和第二短信息在相同的下行控制信息中传输,其中,第二短信息用于确定第二类型终端对应的系统消息的情况。

虚拟资源块到物理资源块映射方式(VRB-to-PRB mapping);
调制编码方案(Modulation and coding scheme);
传输块大小(TB scaling);
预留比特(Reserve bits)。
其中,预留比特占用6bit。短消息中包含系统信息变更(systemInfoModification)的指示,该信息指示第二类型终端除了SIB6、SIB7和SIB8以外的广播控制信道变更(BCCH modification)。
如果网络只配置了CORESET0,且该CORESET0可以同时适用于第一类型终端和第二类型终端,则该CORESET0内的P-RNTI加扰的DCI format 1_0内同时也包含第一类型终端的系统信息变更指示,同时适用于第一类型终端和第二类型终端的P-RNTI加扰的DCI format 1_0包含的信息域为如下至少之一:
短消息指示(Short messages indicator);
短消息(Short messages);
第一类型终端系统信息变更指示;
预留比特(Reserve bits);
或者,同时用于第一类型终端和第二类型终端的P-RNTI加扰的DCI format1_0包含的信息域为如下至少之一:
短消息指示(Short messages indicator);
第二短消息(Short messages)(应用于第二类型终端);
第一短消息(应用于第一类型终端);
预留比特(Reserve bits)。
或者,同时用于第一类型终端和第二类型终端的P-RNTI加扰的DCI format1_0包含的信息域为如下至少之一:
短消息指示(Short messages indicator);
短消息(Short messages);
预留比特(Reserve bits);
此时,第一类型终端的系统信息变更指示包含在短消息中,使用短消息中的预留比特。
如果网络同时配置了第一CORESET0和第二CORESET0,则系统信息变更指示或应用于第一类型终端的短消息包含在第一CORESET0或第二CORESET0内的P-RNTI加扰的DCI format 1_0内。
其中,第一类型终端系统信息变更指示占用DCI format 1_0内的原本预留的比特,或占用应用于第二类型终端的短消息中的预留比特,指示除了SIB6、SIB7和SIB8以外的广播控制信道变更(Broadcast Control Channel modification,BCCH  modification),或指示包括SIB6、SIB7和SIB8在内的BCCH modification。系统信息变更指示为1bit的开销,例如bit为“1”指示变更,或bit为“0指示变更”,也可以用该bit是否存在指示是否变更,例如bit“存在”指示变更,或bit“不存在”指示变更;或者,第一类型终端系统信息变更指示为2bit的开销,以适用于第一类型终端进一步划分了终端类型的情况,具体的指示方式包括如下情况:例如“11”指示所有第一类型终端的系统信息变更,“10”指示第一类型终端中的类型A终端的系统信息变更,“01”指示第一类型终端中的类型B终端的系统信息变更,“00”指示所有第一类型终端系统信息不变更。上述类型A和类型B表示第一类型终端中进一步根据终端能力划分的不同类型的终端。
可选地,第一短消息可至少用于指示第一类型终端对应的系统消息是否改变,第一短消息大小可以与第二短消息大小相同,也可以比第二短消息小,例如,仅包括第一类型终端对应的系统消息是否改变,或者,DCI指示的PDSCH承载SIB的类型,以及第一类型终端对应的系统消息是否改变。
