Description

下行控制信息的传输方法和装置
本申请要求于2018年09月28日提交中国专利局、申请号为201811142741.8、申请名称为“下行控制信息的传输方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,并且更具体地,涉及下行控制信息的传输方法和装置。
背景技术
在通信系统中,终端设备通常需要接到同步/广播信道块(SS/PBCH block,SSB)和剩余最小系统信息(remaining minimum system information,RMSI)后才能获取接入小区的信息,以接入小区。而RMSI由网络设备通过数据信道发送至终端设备,终端设备在接收RMSI之前,需要通过盲检物理下行控制信道PDCCH公共搜索空间,以获取RMSI的下行控制信息(downlink control information,DCI),再根据RMSI的DCI在数据信道上接收RMSI。
目前的通信协议中规定,网络设备需要根据SSB的索引号(index)确定传输RMSI的DCI占用的时隙,相应地,终端设备需要根据SSB的索引号确定用于盲检RMSI的DCI的盲检时隙。通常,网络设备会发送多个SSB,且这多个SSB的索引号对应的多个盲检时隙在时域上连续。
然而,不同的帧结构中,上行时隙、下行时隙以及特殊时隙在时域上的位置关系都不相同,如此,上述时域上连续的多个盲检时隙中很有可能存在冲突时隙,例如,多个盲检时隙中部分的盲检时隙和上行时隙发生冲突,或者说多个盲检时隙中部分的盲检时隙在时域上与上行时隙重叠。此时,即使终端设备接收到SSB,也无法在该SSB的索引号对应的盲检时隙上盲检RMSI的DCI,最终该终端设备将无法接入小区。
发明内容
本申请提供一种下行控制信息的传输方法、终端设备和网络设备,以提高终端设备盲检到RMSI的DCI的概率,从而提高小区的覆盖能力。
第一方面,提供一种下行控制信息的传输方法,包括:终端设备接收来自网络设备的第一同步/广播信道块SSB;当所述第一SSB的索引号对应的PDCCH公共搜索空间的多个第一盲检时隙中的至少一个第一盲检时隙为冲突时隙时,所述终端设备在第二盲检时隙上盲检所述PDCCH公共搜索空间;其中,所述第二盲检时隙包括所述多个所述第一盲检时隙之外的下行时隙或特殊时隙。
在本申请实施例中,当第一盲检时隙中的至少一个第一盲检时隙为冲突时隙时,终端设备可以在第二盲检时隙上盲检第一SSB对应的PDCCH公共搜索空间,提高终端设备接 收第一SSB对应的RMSI的DCI的概率。避免了现有技术中,当第一盲检时隙中的至少一个第一盲检时隙为冲突时隙时,终端设备无法在多个第一盲检时隙上盲检到第一SSB对应的RMSI的DCI。
在一种可能的实现方式中,为所述冲突时隙的第一盲检时隙与上行时隙冲突,或为所述冲突时隙的第一盲检时隙与传输不同于所述DCI的其他DCI占用的时隙冲突。
在一种可能的实现方式中,所述多个第一盲检时隙为所述第一SSB的索引号对应的PDCCH公共搜索空间的全部盲检时隙。
在一种可能的实现方式中,所述多个第一盲检时隙均为所述冲突时隙。
在一种可能的实现方式中,所述第一SSB为一个SSB周期包含的多个SSB中的一个,所述多个SSB的索引号对应的多个盲检时隙组成盲检时隙集合,所述第二盲检时隙包括在时域上位于所述盲检时隙集合之后的时隙。
在本申请实施例中,第二盲检时隙包括在时域上位于盲检时隙集合之后的时隙,以便终端设备在接收到第一SSB之后,有足够的时间在第二盲检时隙上盲检第一SSB对应的PDCCH公共搜索空间。
在一种可能的实现方式中,所述第二盲检时隙包括在时域上位于所述盲检时隙集合之后的第m+1个下行时隙或特殊时隙,m为所述多个SSB中的第二SSB的数量,所述第二SSB的发送时刻早于所述第一SSB的发送时刻,且所述第二SSB的索引号对应的盲检时隙均为所述冲突时隙,m为正整数。
在本申请实施例中,当第一盲检时隙中的至少一个第一盲检时隙为冲突时隙时,终端设备可以直接在盲检时隙集合之后的下行时隙或特殊时隙上盲检,可以使得盲检时隙集合中,其他SSB的索引号对应的不包含冲突时隙的盲检时隙的位置可以不变,也就是说,接收到上述其他SSB的终端设备可以继续根据其他SSB的索引号确定PDCCH公共搜索空间的盲检时隙。有利于降低接收其他SSB的终端设备盲检PDCCH公共搜索空间的复杂度。
在一种可能的实现方式中,所述第一盲检时隙位于第一帧,所述第二盲检时隙包括位于第二帧的时隙,所述第二帧在时域上为所述第一帧的下一帧。
在一种可能的实现方式中,所述第二盲检时隙包括所述第二帧中的第n+1个下行时隙或特殊时隙,n为所述多个SSB中的第三SSB的数量,所述第三SSB的发送时刻早于所述第一SSB的发送时刻,且所述第三SSB的索引号对应的盲检时隙均为冲突时隙,n为正整数。
在本申请实施例中,当第一盲检时隙中的至少一个第一盲检时隙为冲突时隙时,终端设备可以直接在第二帧的下行时隙或特殊时隙上盲检,有利于简化终端设备确定第二盲检时隙在时域上的位置的复杂度。
在一种可能的实现方式中,所述第二盲检时隙包括所述多个所述第一盲检时隙之后的第一个下行时隙或特殊时隙。
在本申请实施例中,当第一盲检时隙中的至少一个第一盲检时隙为冲突时隙时,终端设备可以直接在第一盲检时隙之后的第一个下行时隙或特殊时隙上盲检,即第二盲检时隙与第一盲检时隙在时域上相近,使得终端设备可以迅速在第二盲检时隙上进行盲检,有利于提高终端设备盲检的效率。
在一种可能的实现方式中,所述冲突时隙属于第一盲检周期,所述第二盲检时隙包括属于第二盲检周期的时隙,所述第二盲检周期为所述第一盲检周期的下一个盲检周期。
第二方面,提供一种下行控制信息的传输方法,包括:网络设备发送第一同步/广播信道块SSB;当所述第一SSB的索引号对应的用于发送PDCCH公共搜索空间的多个候选时隙均为冲突时隙时,所述网络设备在目标时隙发送DCI,所述PDCCH公共搜索空间为所述DCI的PDCCH公共搜索空间,所述目标时隙为所述多个候选时隙之外的下行时隙或特殊时隙。
在本申请实施例中,当多个候选时隙均为冲突时隙时,网络设备可以在目标时隙上传输DCI,以便终端设备可以在包含目标时隙的第一盲检时隙上盲检,以提高第一SSB对应的RMSI的DCI被成功传输的概率。避免了现有技术中,当多个候选时隙均为冲突时隙时,第一SSB对应的RMSI的DCI没有可以使用的时隙被传输,有利于提高终端设备接收第一SSB对应的RMSI的DCI的概率。
在一种可能的实现方式中,所述冲突时隙包括与上行时隙冲突的候选时隙,或与传输不同于所述DCI的其他DCI冲突的候选时隙。
在一种可能的实现方式中,所述多个候选时隙为所述第一SSB对应的PDCCH公共搜索空间的全部候选时隙。
在一种可能的实现方式中,所述第一SSB为一个SSB周期包含的多个SSB中的一个,所述多个SSB的索引号对应的用于盲检PDCCH公共搜索空间的时隙组成候选时隙集合,所述目标时隙在时域上位于所述候选时隙集合之后。
在本申请实施例中,目标时隙在时域上位于候选时隙集合之后,以便终端设备在接收到第一SSB之后,有足够的时间在第二盲检时隙上盲检第一SSB对应的PDCCH公共搜索空间。
在一种可能的实现方式中,所述目标时隙为所述候选时隙集合之后的第m+1个下行时隙或特殊时隙,m为所述多个SSB中的第二SSB的数量,所述第二SSB的发送时刻早于所述第一SSB的发送时刻,且所述第二SSB的索引号对应的用于发送DCI的时隙均为冲突时隙,m为正整数。
在本申请实施例中,通过将目标时隙配置为候选时隙集合之后的第m+1个下行时隙或特殊时隙,可以使得候选时隙集合中,其他SSB的索引号对应的不包含冲突时隙的候选时隙的位置可以不变,也就是说,接收到上述其他SSB的终端设备可以继续根据其他SSB的索引号确定PDCCH公共搜索空间的盲检时隙。有利于降低接收其他SSB的终端设备盲检PDCCH公共搜索空间的复杂度。
在一种可能的实现方式中,所述冲突时隙位于第一帧,所述目标时隙位于第二帧,所述第二帧为所述第一帧的下一帧。
在一种可能的实现方式中,所述目标时隙为所述第二帧中的第n+1个下行时隙或特殊时隙,n为所述多个SSB中的第三SSB的数量,所述第三SSB的发送时刻早于所述第一SSB的发送时刻,且所述第三SSB的索引号对应的用于发送DCI的时隙均为冲突时隙,n为正整数。
在本申请实施例中,通过将目标时隙配置为第二帧中的第n+1个下行时隙或特殊时隙,终端设备可以直接在第二帧的下行时隙或特殊时隙上盲检,有利于简化终端设备确定 第二盲检时隙在时域上的位置的复杂度。
在一种可能的实现方式中,所述目标时隙为所述多个候选时隙之后的第一个下行时隙或特殊时隙。
在本申请实施例中,当第一盲检时隙中的至少一个第一盲检时隙为冲突时隙时,终端设备可以直接在第一盲检时隙之后的第一个下行时隙或特殊时隙上盲检,即第二盲检时隙与第一盲检时隙在时域上相近,使得终端设备可以迅速在第二盲检时隙上进行盲检,有利于提高终端设备盲检的效率。
在一种可能的实现方式中,当目标时隙与多个候选时隙位于不同的盲检周期时,目标时隙与目标时隙所在的盲检周期原本要传输的RMSI的DCI占用的时隙不重叠。例如,可以通过预设优先级的方式,配置目标时隙所在的盲检周期中原本要传输的RMSI的DCI优先被传输,那么目标时隙可以占用该盲检周期内空闲的下行时隙或特殊时隙传输。
在本申请实施例中,当目标时隙与多个候选时隙位于不同的盲检周期时,目标时隙与目标时隙所在的盲检周期原本要传输的RMSI的DCI占用的时隙不重叠,以保证每个SSB对应的RMSI的DCI有可用的时隙可以传输。

为了便于理解,先介绍本申请实施例涉及的相关概念。
一、SSB:包括同步信号(synchronization signal,SS)以及物理广播信道(physical broadcast channel,PBCH)。
通常,一个下行时隙中可以传输两个SSB。网络设备在一个SSB周期内发送多个SSB,这一个周期内的SSB的索引号以0为起点,以步长为1的方式递增。例如,网络设备需要在一个SSB周期内发送2个SSB时,这两个SSB的索引号分别为0和1。
另外,在一个发送周期内,多个SSB的发送顺序与SSB的索引号的递增顺序相同,也就是说,SSB的索引号越小,SSB的发送时刻越早。
二、RMSI:RMSI中携带用于指示终端设备接入小区的信息,例如,小区接入过程中需要的系统信息,或者小区选择过程中需要的系统信息。
为了减少PBCH上发送的系统信息的大小,可以将系统信息分为两部分:最小系统信息,以及剩余最小系统信息,其中,最小系统信息可以通过PBCH发送,剩余最小系统信息可以通过下行共享信道(physical downlink shared channel,PDSCH)(例如,NR-PDSCH)进行发送。
三、盲检时隙及候选时隙:盲检时隙可以理解为终端设备用于盲检RMSI的DCI的时隙,或者说,用于终端设备盲检物理下行控制信道(physical downlink control channel,PDCCH)公共搜索空间(common search space,CSS)的时隙,上述PDCCH公共搜索空间为用于盲检RMSI的DCI的PDCCH公共搜索空间,例如,5G通信协议中规定的0型(Type0-PDCCH)公共搜索空间。
通常,一个RMSI的DCI占用一个时隙,但是终端设备可以在多个盲检时隙上盲检一个RMSI的DCI,即一个RMSI的DCI对应多个盲检时隙。例如,在5G通信协议中定义了3种SSB和RMSI的控制资源集合的复用模式,即时分复用模式,时分复用以及频分复用模式,以及频分复用模式。在SSB和RMSI的控制资源集合的复用模式为时分复用模式时,终端设备被配置在两个盲检时隙上盲检RMSI的DCI。
相应地,一个RMSI的DCI对应多个盲检时隙,对于网络设备而言,可以理解为一个RMSI的DCI可以对应多个候选时隙,即网络设备可以从一个RMSI的DCI对应的多个候选时隙中选择一个时隙作为发送RMSI的DCI的时隙(例如,下文中的目标时隙)。
在本申请实施例中,第一SSB的索引号对应的多个第一盲检时隙,可以理解为用于盲检第一SSB对应的RMSI的DCI的时隙,其中,第一SSB对应的RMSI的DCI可以指接收第一SSB的终端设备需要盲检的RMSI的DCI。当SSB和RMSI的控制资源集合的复用模式为时分复用模式时,上述多个第一盲检时隙可以为在时域上连续的两个时隙。
第二盲检时隙也可以包括多个盲检时隙,但是第二盲检时隙包括的多个盲检时隙可以是时域上不连续的时隙,也可以是时域上连续的时隙。当SSB和RMSI的控制资源集合的复用模式为时分复用模式时,上述第二盲检时隙的数量可以为2。
目标时隙是网络设备用于发送第一SSB对应的RMSI的DCI占用的时隙,目标时隙为第二盲检时隙中的一个时隙。
需要说明的是,在本申请实施例中,除了特殊说明,上述第一盲检时隙、候选时隙在时域上的位置皆为根据SSB的索引号计算得到的,可以理解为第一盲检时隙和候选时隙对应的相同的时隙。而第二盲检时隙和目标时隙虽然是SSB对应的时隙,但第二盲检时隙中的至少部分盲检时隙,以及目标时隙在时域上的位置不是基于SSB索引号计算得到的时隙。其中,第二盲检时隙中的至少部分盲检时隙包括全部第二盲检时隙,或第一盲检时隙中的部分盲检时隙。
四、冲突时隙:可以理解为被占用的时隙,冲突时隙可以是盲检时隙也可以是候选时隙。下面说明产生冲突时隙的三种冲突产生原因。
冲突产生原因一,与上行时隙冲突。若某一时隙被配置为用于传输DCI的时隙时,该时隙需要是下行时隙或特殊时隙,但是若根据当前的帧结构确定该时隙为上行时隙时,该时隙即为冲突时隙。
冲突产生原因二,与传输其他DCI的时隙冲突。若某一时隙为传输第一SSB对应的RMSI的DCI占用的时隙的同时,该时隙还为传输除第一SSB之外的其他SSB对应的RMSI的DCI占用的时隙,则该时隙为冲突时隙。
冲突产生原因三,与传输其他DCI的候选时隙(或盲检时隙)冲突。若某一时隙同时属于多个PDCCH公共搜索空间,或者说某一时隙同时为不同的RMSI的DCI的候选时隙,则该时隙为冲突时隙。
需要说明的是,本申请实施例中的“第一盲检时隙”有时也可称为“第一时隙”,“第二盲检时隙”有时也可称为“第二时隙”。
图2示出了传统的PDCCH公共搜索空间占用的时隙的示意图。在载波频率为3.5G,且帧配比为7:3的情况下,目前通信协议定义了16组公共搜索空间盲检参数,每组公共搜索空间盲检参数对应一个参数索引号(index),16组公共搜索空间盲检参数对应的参数索引号从Index0至Index15。
图2所示的每个系统帧包含20个时隙,从编号0至编号19,且每个系统帧中包含上行时隙(用U表示)、下行时隙(用D表示)以及特殊时隙(用S表示)。当传输8个SSB时,每个时隙可以承载两个SSB,8个SSB一共占用4个连续的可用时隙(包括下行时隙和特殊时隙)。基于上述8个SSB的索引号,以及每个参数索引号对应的PDCCH公共搜索空间参数可以确定8个SSB对应的PDCCH公共搜索空间组成的盲检时隙集合。
例如,当使用Index 1对应的公共搜索空间参数时,SSB0至SSB7对应的盲检时隙集合包括编号0至编号8的时隙。其中,SSB0对应的用于PDCCH公共搜索空间的盲检时隙为时隙0和时隙1,SSB1对应的用于PDCCH公共搜索空间的盲检时隙为时隙1和时隙2,SSB2对应的用于PDCCH公共搜索空间的盲检时隙为时隙2和时隙3,SSB3对应的用于PDCCH公共搜索空间的盲检时隙为时隙3和时隙4,SSB4对应的用于PDCCH公共搜索空间的盲检时隙为时隙4和时隙5,SSB5对应的用于PDCCH公共搜索空间的盲检时隙为时隙5和时隙6,SSB6对应的用于PDCCH公共搜索空间的盲检时隙为时隙6和时隙7,SSB7对应的用于PDCCH公共搜索空间的盲检时隙为时隙7和时隙。相应地,传输每个SSB对应的RMSI的DCI的候选时隙,与上述每个SSB对应的用于PDCCH公共搜索空 间的盲检时隙的时隙编号相同。
网络设备可以在编号0至编号3的时隙上,传输SSB0至SSB3对应的RMSI的DCI。由于编号4的时隙为上行时隙,即SSB4对应的传输RMSI的DCI的两个候选时隙中包含一个上行时隙,因此网络设备会选择另一个候选时隙(即编号为5的下行时隙)传输RMSI的DCI,依次类推,网络设备会在编号5至编号7的时隙上,传输SSB4至SSB6对应的RMSI的DCI。但是,SSB7对应的传输RMSI的DCI的两个候选时隙中,一个被SSB6对应的RMSI的DCI占用(即编号为7的时隙),另一个为上行时隙(即编号为8的时隙),也就是说,SSB7对应的传输RMSI的DCI没有下行时隙或特殊时隙可以占用。对于接收到SSB7的终端设备而言,该终端设备在SSB7对应的用于PDCCH的公共搜索空间对应的盲检时隙上检测不到RMSI的DCI,则该终端设备无法接入小区。
从图2所示的PDCCH公共搜索空间的盲检时隙分布可以看出,每组PDCCH公共搜索空间参数确定盲检时隙集合中,总会存在盲检时隙与上行时隙冲突的情况,即盲检时隙集合中包含冲突时隙。也就是说,基于目前协议规定,根据SSB的索引号以及PDCCH的盲检参数确定PDCCH盲检时隙的方法,无法避免盲检时隙集合中存在冲突时隙的情况,导致部分终端设备即使接收到了SSB,也无法在PDCCH的盲检时隙上检测到RMSI的DCI。
为了降低上述由于冲突时隙的存在,导致终端设备即使接收到SSB也无法在PDCCH的盲检时隙上检测到RMSI的DCI的情况,本申请提供了一种下行控制信息的传输方法。下文结合图3描述本申请实施例的下行控制信息的传输方法。图3所示的传输方法包括步骤310至步骤340。
310,网络设备向终端设备发送第一SSB。
320,当第一SSB的索引号对应的用于发送PDCCH公共搜索空间的多个候选时隙包括冲突时隙时,网络设备在目标时隙发送DCI。所述PDCCH公共搜索空间为所述DCI的PDCCH公共搜索空间,所述目标时隙为所述多个候选时隙之外的下行时隙或特殊时隙。
上述用于发送PDCCH的公共搜索空间的多个候选时隙包括冲突的时隙,可以指多个候选时隙中的一个候选时隙为冲突时隙,或者多个候选时隙中包括冲突时隙的数量为多个。
若上述多个候选时隙中包括多个冲突时隙时,这多个冲突时隙可以是基于上文相同的冲突产生原因形成的冲突时隙,这多个冲突时隙还可以是基于上文中不同的冲突产生的原因形成的冲突时隙,本申请对此不作具体限定。
参见上文对冲突时隙的定义,上述冲突时隙可以指与上行时隙重叠的候选时隙,上述冲突时隙还可以是被除第一SSB的索引号的其他SSB的索引号对应的RMSI的DCI占用的候选时隙,上述冲突时隙还可以是与其他SSB的索引号对应的PDCCH公共搜索空间的候选时隙重叠的时隙。
上述多个候选时隙可以包括根据所述第一SSB的索引号确定的全部用于传输PDCCH公共搜索空间的候选时隙。
上述目标时隙为所述多个候选时隙之外的下行时隙或特殊时隙,可以包括目标时隙为所述多个候选时隙之外的下行时隙,或者目标时隙为所述多个候选时隙之外的特殊时隙。
上述目标时隙在时域上的位置可以位于多个候选时隙之后,也可以位于多个候选时隙 之前,只要目标时隙在时域上的位置可以满足终端设备接收第一SSB之后,来得及在目标时隙上检测第一SSB对应的PDCCH公共搜索空间。本申请实施例对此不作具体限定,当然,若目标时隙位于候选时隙之后,可以确保终端设备在接收第一SSB之后,在目标时隙上检测第一SSB对应的PDCCH公共搜索空间,以提高终端设备检测到第一SSB对应的PDCCH公共搜索空间的概率。
需要说明的是,网络设备确定多个候选时隙包括冲突时隙的时机,可以是在网络设备有待发送的第一SSB时,网络设备确定多个候选时隙包括冲突时隙的时机。也可以是,网络设备基于一个SSB周期内的全部SSB的索引号提前确定的。本申请实施例对此不作具体限定。
另外,在网络设备通过目标时隙发送第一SSB对应的RMSI的DCI之后,相应地终端设备需要在包含目标时隙的盲检时隙(即第二盲检时隙)中检测第一SSB对应的PDCCH公共搜索空间,以获得第一SSB对应的RMSI的DCI。因此,网络设备和终端设备需要基于相应的规则确定目标时隙的位置,具体地,可以通过预设的通信协议规定网络设备和终端设备确定目标时隙的方式。
可选地,上述目标时隙可能与多个候选时隙位于同一帧,也可能目标时隙所在的帧与多个候选时隙所在的帧为不同的帧,例如,位于多个候选时隙所在的帧的下一帧。
当然,上述目标时隙可以与多个候选时隙(或者下文中的多个第一盲检时隙)位于相同的盲检周期,上述目标时隙也可以与多个候选时隙位于不同的盲检周期。当目标时隙与多个候选时隙位于不同的盲检周期时,目标时隙与目标时隙所在的盲检周期原本要传输的RMSI的DCI占用的时隙不重叠。例如,可以通过预设优先级的方式,配置目标时隙所在的盲检周期中原本要传输的RMSI的DCI优先被传输,那么目标时隙可以占用该盲检周期内空闲的下行时隙或特殊时隙传输。
330,终端设备在第二盲检时隙上盲检所述PDCCH公共搜索空间,其中,所述第二盲检时隙包括所述多个所述第一盲检时隙之外的下行时隙或特殊时隙。
相应地,当上述第一SSB的索引号对应的PDCCH公共搜索空间的多个第一盲检时隙中的至少一个第一盲检时隙为冲突时隙时,终端设备在第二盲检时隙上盲检PDCCH。第二盲检时隙包括上述目标时隙,即网络设备发送第一SSB对应的RMSI的DCI占用的时隙。
上述多个第一盲检时隙中的至少一个第一盲检时隙为冲突时隙,可以包括多个第一盲检时隙中的对个第一盲检时隙为冲突时隙,或者多个第一盲检时隙中的一个第一盲检时隙为冲突时隙。
基于上文对冲突时隙的定义,为冲突时隙的第一盲检时隙可以是与上行时隙冲突的第一盲检时隙,或者是第一盲检时隙中同时用于传输除第一SSB之外的SSB对应的RMSI的DCI,冲突时隙还可以是第一盲检时隙中同时还作为其他SSB对应的PDCCH公共搜索空间的盲检时隙。
若上述多个第一盲检时隙中包括多个冲突时隙时,这多个冲突时隙可以是基于上文相同的冲突产生原因形成的冲突时隙,这多个冲突时隙还可以是基于上文中不同的冲突产生的原因形成的冲突时隙,本申请对此不作具体限定。
上述第二盲检时隙包括所述多个第一盲检时隙之外的下行时隙或特殊时隙,可以包括 上述第二盲检时隙可以包括除第一盲检时隙之外的下行时隙或特殊时隙的同时,第二盲检时隙还包括第一盲检时隙中的一个或多个盲检时隙。或者,还可以包括上述第二盲检时隙为除第一盲检时隙之外的一个或多个下行时隙或特殊时隙。
基于上文所述,第二盲检时隙包括目标时隙,即网络设备实际传输第一SSB对应的RMSI的DCI占用的时隙,因此,基于上文中目标时隙与候选时隙之间的位置关系,第二盲检时隙与第一盲检时隙在时域上可以具有与目标时隙与候选时隙之间相同的位置关系,为了简洁,在此不再赘述。
需要说明的是,终端设备确定第一盲检时隙包括冲突时隙的时机,可以是在终端设备接收网络设备发送的第一SSB之前。或者是终端设备仅仅在第一个PDCCH盲检周期中确定第二盲检时隙在时域上的位置,并在之后的PDCCH的盲检周期中沿用之前确定的第二盲检时隙在时域上的位置,本申请实施例对此不作具体限定。
可选地,在上述步骤320和330中,根据SSB的索引号确定SSB对应的多个第一盲检时隙(或者候选时隙)可以通过下列公式确定
Figure PCTCN2019099777-appb-000001
确定,其中,n 0,n 0+1表示盲检RMSI的DCI的时隙的编号,O和M可以通过查现有的通信协议38.211章节中表13-11至13-15可以确定,i表示SSB的索引号,μ∈{0,1,2,3}对应的子载波间隔{15,30,60,120}。且当

时,n 0在编号为偶数的系统帧上;当
Figure PCTCN2019099777-appb-000003
时,n 0在编号为奇数的系统帧上。
需要说明的是,可以通过查现有的通信协议38.211章节中表13-11至13-15可以确定O和M的取值,为了简洁,在此不再赘述。
当然,根据SSB的索引号确定上述时隙,还可以兼容未来通信协议的计算方式,本申请在此不作具体限定。
下文结合图4至图6重点介绍几种目标时隙在时域上的位置。
需要说明的是,无论是从第一SSB对应的PDCCH公共搜索空间的盲检时隙的角度,还是从传输第一SSB对应的RMSI的DCI占用的时隙的角度而言,相对重要的是真正承载第一SSB对应的RMSI的DCI的目标时隙在时域上的位置,至于候选时隙(或者说第二盲检时隙)还包括除目标时隙之外的哪些时隙,本申请不作具体限定。例如,可以包括在时域上位于目标时隙之前的时隙,或者包括在时域上位于目标时隙之后的时隙。
位置一,目标时隙可以位于盲检时隙集合之后。
即,第一SSB为一个SSB周期包含的多个SSB中的一个,所述多个SSB的索引号对应的多个盲检时隙组成盲检时隙集合,所述第二盲检时隙包括在时域上位于所述盲检时隙集合之后的时隙。
上述一个SSB周期包含的多个SSB,可以是协议规定的在一个SSB周期内的SSB最大发送个数,例如,子载波间隔为15kHz或者30kHz,载波频率小于等于3GHz时,SSB最大发送个数为4。又例如,子载波间隔为15kHz或者30kHz,载波频率小于3GHz且小 于6GHz时,SSB最大发送个数8。再例如,子载波间隔为120kHz或者240kHz,SSB最大发送个数64。上述一个SSB周期包含的多个SSB还可以是网络设备在一个SSB周期内实际发送的SSB的数量。
需要说明的是,从网络设备传输RMSI的DCI的过程来看,上述盲检时隙集合即为候选时隙集合,候选时隙集合包括根据上述多个SSB的索引号确定的全部候选时隙。
若上述目标时隙的位置需要根据盲检时隙集合(或候选时隙集合)在时域上的位置确定,网络设备和终端设备需要基于相同的“多个SSB的索引号”确定盲检时隙集合(或候选时隙集合)。假设上述多个SSB是网络设备在一个SSB周期内实际发送的SSB的数量,那么这个SSB的数量需要通知给终端设备。
需要说明的是,上述目标时隙可能与盲检时隙集合位于同一帧,也可能位于盲检时隙集合所在的帧之后的帧中,例如,位于盲检时隙集合所在的帧的下一帧。
当然,上述目标时隙可以与盲检时隙集合位于相同的盲检周期,上述目标时隙也可以与盲检时隙集合位于不同的盲检周期。当目标时隙与盲检时隙集合位于不同的盲检周期时,目标时隙与目标时隙所在的盲检周期原本要传输的RMSI的DCI占用的时隙不重叠。例如,可以通过预设优先级的方式,配置目标时隙所在的盲检周期原本要传输的RMSI的DCI优先被传输,那么目标时隙可以占用该盲检周期内空闲的下行时隙或特殊时隙传输。
在位置一的第一种可能的实现方式中,目标时隙为候选时隙集合之后的第m+1个下行时隙或特殊时隙,m为所述多个SSB中的第二SSB的数量,所述第二SSB的发送时刻早于所述第一SSB的发送时刻,且所述第二SSB的索引号对应的用于发送DCI的时隙均为冲突时隙。相应地,第二盲检时隙包括目标时隙。
上述第二SSB的索引号对应的用于发送DCI的时隙均为冲突时隙,可以理解为,根据第二SSB的索引号确定的用于发送RMSI的DCI的候选时隙均为冲突时隙。
图4示出了目标时隙在时域上与盲检时隙集合之间的位置关系。假设上述多个SSB的数量为8个,且根据这8个SSB的索引号确定的盲检时隙集合包括编号10至编号18的盲检时隙,且终端设备分别在两个连续的盲检时隙上盲检一个SSB对应的RMSI的DCI,即SSB0对应的PDCCH公共搜索空间的盲检时隙为编号为10和编号为11的时隙,SSB1对应的PDCCH公共搜索空间的盲检时隙为编号为11和编号为12的时隙,SSB2对应的PDCCH公共搜索空间的盲检时隙为编号为12和编号为13的时隙,SSB3对应的PDCCH公共搜索空间的盲检时隙为编号为13和编号为14的时隙,SSB4对应的PDCCH公共搜索空间的盲检时隙为编号为14和编号为15的时隙,SSB5对应的PDCCH公共搜索空间的盲检时隙为编号为15和编号为16的时隙,SSB6对应的PDCCH公共搜索空间的盲检时隙为编号为16和编号为17的时隙,SSB7对应的PDCCH公共搜索空间的盲检时隙为编号为17和编号为18的时隙。
其中,SSB0至SSB4对应的RMSI的DCI分别占用编号10至编号13的时隙传输,由于在盲检时隙集合中存在一个与上行传输重叠的盲检时隙,即编号为14的时隙,使得SSB5至SSB7对应的RMSI的DCI分别占用编号15至编号17的时隙传输,在SSB7对应的编号为17和编号为18的时隙中,编号为17的特殊时隙被SSB6对应的RMSI的DCI占用,编号为18的时隙是上行时隙,无法传输RMSI的DCI,即8个SSB中只有SSB7对应的用于发送DCI的时隙为冲突时隙,则8个SSB中上述第二SSB的数量为0,即m=0, 因此,目标时隙为盲检时隙集合(或者候选时隙集合)之后的第0+1个下行时隙或特殊时隙,即盲检时隙集合的下一帧中编号为0的时隙(参见410)。
需要说明的是,上述包含目标时隙的第二盲检时隙为2个的情况下,第二盲检时隙还可以包括目标时隙之前的一个时隙,即编号为19的上行时隙。或者第二盲检时隙还可以包括目标时隙之后的一个时隙,即编号为1的下行时隙,本申请实施例对此不作限定。
又例如,图11示出了目标时隙在时域上与盲检时隙集合之间的位置关系。假设上述多个SSB的数量为8个,且根据这8个SSB的索引号确定的盲检时隙集合包括编号10至编号18的盲检时隙,且终端设备分别在两个连续的盲检时隙上盲检一个SSB对应的RMSI的DCI,即SSB0对应的PDCCH公共搜索空间的盲检时隙为编号为10和编号为11的时隙,SSB1对应的PDCCH公共搜索空间的盲检时隙为编号为11和编号为12的时隙,SSB2对应的PDCCH公共搜索空间的盲检时隙为编号为12和编号为13的时隙,SSB3对应的PDCCH公共搜索空间的盲检时隙为编号为13和编号为14的时隙,SSB4对应的PDCCH公共搜索空间的盲检时隙为编号为14和编号为15的时隙,SSB5对应的PDCCH公共搜索空间的盲检时隙为编号为15和编号为16的时隙,SSB6对应的PDCCH公共搜索空间的盲检时隙为编号为16和编号为17的时隙,SSB7对应的PDCCH公共搜索空间的盲检时隙为编号为17和编号为18的时隙。
其中,由于在盲检时隙集合中存在与上行传输重叠的盲检时隙,即编号为11、12、14以及18的时隙,使得SSB0对应的RMSI的DCI占用编号为10的时隙传输,SSB1对应的编号为11和编号为12的两个时隙都与上行时隙重叠,从而没有可用的时隙发送SSB1对应的RMSI的DCI,SSB2对应的RMSI的DCI占用编号为13的时隙传输,SSB3对应的两个时隙均为冲突时隙,即SSB3对应的RMSI的DCI没有可用的时隙传输,SSB4-SSB6对应的RMSI的DCI分别占用编号为15至17的时隙传输,SSB7对应的两个时隙也均为冲突时隙,没有可用的时隙传输SSB7对应的RMSI的DCI。
综上,SSB0至SSB7中,SSB1,SSB3以及SSB7对应的RMSI的DCI没有可用的时隙传输,按照上述位置一的第一种可能的实现方式,重新确定SSB1对应的目标时隙为第二帧中编号为0的下行时隙,SSB3对应的目标时隙为第二帧中编号为1的下行时隙,SSB7对应的目标时隙为第二帧中编号为2的下行时隙(参见1110)。
需要说明的是,上述SSB1,SSB3以及SSB7分别对应的第二盲检时隙包括上述目标时隙之外,还可以包括上述SSB1,SSB3以及SSB7分别目标时隙的前一个时隙或后一个时隙。
在位置一的第二种可能的实现方式中,第一盲检时隙位于第一帧,目标时隙位于第二帧,所述第二帧在时域上为所述第一帧的下一帧。目标时隙为所述第二帧中的第n+1个下行时隙或特殊时隙,n为所述多个SSB中的第三SSB的数量,所述第三SSB的发送时刻早于所述第一SSB的发送时刻,且所述第三SSB对应的盲检时隙均为冲突时隙。
图5示出了目标时隙在时域上与盲检时隙集合之间的位置关系。假设上述多个SSB的数量为8个,且根据这8个SSB的索引号确定的盲检时隙集合包括编号10至编号18的盲检时隙,且终端设备分别在两个连续的盲检时隙上盲检一个SSB对应的RMSI的DCI,即SSB0对应的PDCCH公共搜索空间的盲检时隙为编号为10和编号为11的时隙,SSB1对应的PDCCH公共搜索空间的盲检时隙为编号为11和编号为12的时隙,SSB2对应的 PDCCH公共搜索空间的盲检时隙为编号为12和编号为13的时隙,SSB3对应的PDCCH公共搜索空间的盲检时隙为编号为13和编号为14的时隙,SSB4对应的PDCCH公共搜索空间的盲检时隙为编号为14和编号为15的时隙,SSB5对应的PDCCH公共搜索空间的盲检时隙为编号为15和编号为16的时隙,SSB6对应的PDCCH公共搜索空间的盲检时隙为编号为16和编号为17的时隙,SSB7对应的PDCCH公共搜索空间的盲检时隙为编号为17和编号为18的时隙。
其中,SSB0至SSB4对应的RMSI的DCI分别占用编号10至编号13的时隙传输,由于在盲检时隙集合中存在一个与上行传输重叠的盲检时隙,即编号为14的时隙,使得SSB5至SSB7对应的RMSI的DCI分别占用编号15至编号17的时隙传输,在SSB7对应的编号为17和编号为18的时隙中,编号为17的特殊时隙被SSB6对应的RMSI的DCI占用,编号为18的时隙是上行时隙,无法传输RMSI的DCI,即8个SSB中只有SSB7对应的用于发送DCI的时隙为冲突时隙,则8个SSB中上述第三SSB的数量为0,即n=0,因此,目标时隙为下一帧的第0+1个下行时隙或特殊时隙(参见510)。
需要说明的是,上述包含目标时隙的第二盲检时隙为2个的情况下,第二盲检时隙还可以包括目标时隙之前的一个时隙,即编号为19的上行时隙。或者第二盲检时隙还可以包括目标时隙之后的一个时隙,即编号为1的下行时隙,本申请实施例对此不作限定。
又例如,基于图11的情况,由于在盲检时隙集合中存在与上行传输重叠的盲检时隙,即编号为11、12、14以及18的时隙,使得SSB0对应的RMSI的DCI占用编号为10的时隙传输,SSB1对应的编号为11和编号为12的两个时隙都与上行时隙重叠,从而没有可用的时隙发送SSB1对应的RMSI的DCI,SSB2对应的RMSI的DCI占用编号为13的时隙传输,SSB3对应的两个时隙均为冲突时隙,即SSB3对应的RMSI的DCI没有可用的时隙传输,SSB4-SSB6对应的RMSI的DCI分别占用编号为15至17的时隙传输,SSB7对应的两个时隙也均为冲突时隙,没有可用的时隙传输SSB7对应的RMSI的DCI。
综上,SSB0至SSB7中,SSB1,SSB3以及SSB7对应的RMSI的DCI没有可用的时隙传输,按照上述位置一的第二种可能的实现方式,重新确定SSB1对应的目标时隙为第二帧中编号为0的下行时隙,SSB3对应的目标时隙为第二帧中编号为1的下行时隙,SSB7对应的目标时隙为第二帧中编号为2的下行时隙(参见1110)。
需要说明的是,上述SSB1,SSB3以及SSB7分别对应的第二盲检时隙包括上述目标时隙之外,还可以包括上述SSB1,SSB3以及SSB7分别目标时隙的前一个时隙或后一个时隙。
位置二,当所述第一SSB的索引号对应的用于发送PDCCH公共搜索空间的多个候选时隙均为冲突时隙时,目标时隙为所述多个候选时隙之后的第一个下行时隙或特殊时隙。或者说,当所述第一SSB的索引号对应的PDCCH公共搜索空间的多个第一盲检时隙中的至少一个第一盲检时隙为冲突时隙时,第二盲检时隙包括所述多个所述第一盲检时隙之后的第一个下行时隙或特殊时隙。
图6示出了目标时隙在时域上与盲检时隙集合之间的位置关系。假设上述多个SSB的数量为8个,且根据这8个SSB的索引号确定的盲检时隙集合包括编号10至编号18的盲检时隙,且终端设备分别在两个连续的盲检时隙上盲检一个SSB对应的RMSI的DCI,即SSB0对应的PDCCH公共搜索空间的盲检时隙为编号为10和编号为11的时隙,SSB1 对应的PDCCH公共搜索空间的盲检时隙为编号为11和编号为12的时隙,SSB2对应的PDCCH公共搜索空间的盲检时隙为编号为12和编号为13的时隙,SSB3对应的PDCCH公共搜索空间的盲检时隙为编号为13和编号为14的时隙,SSB4对应的PDCCH公共搜索空间的盲检时隙为编号为14和编号为15的时隙,SSB5对应的PDCCH公共搜索空间的盲检时隙为编号为15和编号为16的时隙,SSB6对应的PDCCH公共搜索空间的盲检时隙为编号为16和编号为17的时隙,SSB7对应的PDCCH公共搜索空间的盲检时隙为编号为17和编号为18的时隙。
由于根据SSB3的索引号确定编号为13和编号为14的时隙中编号为14的时隙为上行时隙,即冲突时隙,此时,第一SSB为SSB3,则第二盲检时隙包括第一盲检时隙(编号为13和编号为14的时隙)之后的第一个下行时隙,即编号为15的时隙,也就是说,SSB3对应的第二盲检时隙包括编号为13和编号为15的时隙。此时,由于编号为15的时隙属于SSB3对应的第二盲检时隙,则SSB4对应的第一盲检时隙中存在冲突时隙(编号为15的时隙),此时,第一SSB为SSB4,则第二盲检时隙包括第一盲检时隙(编号为14和编号为15的时隙)之后的第一个下行时隙,即编号为16的时隙,也就是说,SSB4对应的第二盲检时隙包括编号为15和编号为16的时隙,依次类推,SSB5对应的第二盲检时隙为编号为16和编号为17的时隙,SSB6对应的第二盲检时隙为编号为17和编号为18的时隙,SSB7对应的第二盲检时隙为第二帧中编号为0和编号为1的时隙。
相应地,SSB0至对应的目标时隙为编号10的时隙,SSB1至对应的目标时隙为编号11的时隙,SSB2至对应的目标时隙为编号12的时隙,SSB3至对应的目标时隙为编号13的时隙,SSB4至对应的目标时隙为编号15的时隙,SSB5至对应的目标时隙为编号16的时隙,SSB6至对应的目标时隙为编号17的时隙,SSB7至对应的目标时隙为第二帧中编号0的时隙(参见610)。
