Description

一种资源的指示方法和通信设备 技术领域
本申请实施例涉及通信领域,尤其涉及一种资源的指示方法和通信设备。
背景技术
第五代无线通信***中使用了新无线接入技术(new radio access technology,NR)。与演进型长期演进(long term evolution-advanced,LTE-A)***相比,使用NR的第五代无线通信***(简称为NR***)具有更大的单载波带宽和更灵活的部署频段。尽管NR***的商用即将到来,但LTE-A***在短期内(甚至长期)仍将继续提供无线通信服务,因此,NR***与LTE-A***的共存成为了一个重要的研究点。
由于LTE-A***仍在进行服务,因此它将继续占用其工作频段(如1.8GHz附近的频段),NR***可以与LTE-A***以共享频谱的方式进行共存。例如,在某个频段上、以同站址(或异站址)的方式同时部署NR***与LTE-A***,对于该频段上的一些时频资源,既可能被NR网络设备和NR用户设备(User Equipment,UE)使用,也可能被LTE-A网络设备和LTE-A UE使用;当NR网络设备和NR UE使用该时频资源时,LTE-A网络设备和LTE-A UE不使用该时频资源,反之亦然。
例如,增强型机器类通信(enhanced Machine Type Communication,eMTC)***是在LTE-A***基础上衍生的***,eMTC***在LTE-A***中可使用LTE频段进行工作。为了节省功耗,降低成本,eMTC终端的工作带宽通常可能较小,小于LTE-A***的工作带宽,例如eMTC终端的工作带宽可以是一个窄带(narrow band,NR),一个NB包括6个连续的物理资源块(physical resource block,PRB),一个物理资源块包括12个子载波(Subcarrier,SC)。当eMTC***与NR***同时出现时,eMTC***工作于NR频段上,避免eMTC***与NR***之间的干扰是一个需要考虑的重要问题。
在NR***中存在需要LTE-A***预留资源的信号,例如同步信号块(synchronization signal block,SSB)用于用户与网络的时间同步。在NR***中,SSB的子载波间隔可以为:15kHz,30kHz,60kHz,120kHz,240kHz,LTE-A***中,SSB的子载波间隔只有15kHz这一种间隔。相应的,在NR***和LTE-A***中,SSB在不同频域上子载波间隔不同,时域上符号的长度也同样不同。
目前,LTE-A***中使用比特位图的方式来指示预留资源。在NR***中时域和频域均使用比特位图的方式来指示预留资源,时域上的比特位图的颗粒度为符号,频域比特位图的颗粒度为资源块。如果使用LTE-A***中的比特位图方式来指示SSB,会导致严重的资源浪费。如果使用NR***中的时频域的比特位图方式来指示SSB,会使得信令开销过大。

图1示出了本申请实施例的一种可能的无线接入网(radio access network,RAN)的结构示意图。所述RAN可以为2G网络的基站接入***(即所述RAN包括基站和基站控制器),或可以为3G网络的基站接入***(即所述RAN包括基站和RNC),或可以为4G网络的基站接入***(即所述RAN包括eNB和RNC),或可以为5G网络的基站接入***。
所述RAN包括一个或多个网络设备。所述网络设备可以是任意一种具有无线收发功能的设备,或,设置于具体无线收发功能的设备内的芯片。所述网络设备包括但不限于:基站(例如基站BS,基站NodeB、演进型基站eNodeB或eNB、第五代5G通信***中的基站gNodeB或gNB、未来通信***中的基站、WiFi***中的接入节点、无线中继节点、无线回传节点)等。基站可以是:宏基站,微基站,微微基站,小站,中继站等。多个基站可以支持上述提及的一种或者多种技术的网络,或者未来演进网络。所述核心网可以支持上述提及一种或者多种技术的网络,或者未来演进网络。基站可以包含一个或多个共站或非共站的传输接收点(transmission receiving point,TRP)。网络设备还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器、集中单元(centralized unit,CU)或者分布单元(distributed unit,DU)等。网络设备还可以是服务器,可穿戴设备,或车载设备等。以下以网络设备为基站为例进行说明。所述多个网络设备可以为同一类型的基站,也可以为不同类型的基站。基站可以与终端设备1-6进行通信,也可以通过中继站与终端设备1-6进行通信。终端设备1-6可以支持与不同技术的多个基站进行通信,例如,终端设备可以支持与支持LTE网络的基站通信,也可以支持与支持5G网络的基站通信,还可以支持与LTE网络的基站以及5G网络的基站的双连接。例如将终端接入到 无线网络的RAN节点。目前,一些RAN节点的举例为:gNB、传输接收点(transmission reception point,TRP)、演进型节点B(evolved Node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(Node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved NodeB,或home Node B,HNB)、基带单元(base band unit,BBU),或无线保真(wireless fidelity,Wifi)接入点(access point,AP)等。在一种网络结构中,网络设备可以包括集中单元(centralized unit,CU)节点、或分布单元(distributed unit,DU)节点、或包括CU节点和DU节点的RAN设备。
终端设备1-6,又称之为用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)、终端等,是一种向用户提供语音和/或数据连通性的设备,或,设置于该设备内的芯片,例如,具有无线连接功允许的手持式设备、车载设备等。目前,一些终端设备的举例为:手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,虚拟现实(virtual reality,VR)设备、增强现实(augmented reality,AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。本申请实施例提供的终端设备可以是低复杂度终端设备和/或处于覆盖增强A模式下的终端设备。
在本申请实施例中,基站和UE1至UE6组成一个通信***,在该通信***中,基站发送***信息、RAR消息和寻呼消息中的一种或多种给UE1至UE6中的一个或多个UE,此外,UE4至UE6也组成一个通信***,在该通信***中,UE5可以作为基站的功能实现,UE5可以发送***信息、控制信息和寻呼消息中的一种或多种给UE4和UE6中的一个或多个UE。
在本申请实施例中,SSB的子载波间隔为15kHz时,SSB在时域上占用最多4个符号,如果使用LTE-A***的比特位图方式来指示有效子帧或无效子帧(一个子帧包括的符号数为14个),会导致严重的资源浪费。另外,如果按照NR***中的时频域的比特位图方式来指示又会使得信令开销过大,而SSB的结构是相对固定的,没有必要引入过大的灵活性。
在本申请实施例中,控制资源集(control resource set,coreset)用于指示NR***的物理下行控制信道(physical downlink control channel,PDCCH)所使用的时频资源。在频域上将所有资源块(resource block,RB)按照每6个RB一组的方式划分为多组,并用比特位图的方式指示整个带宽内多组RB的使用情况,时间上可以为1个符号或连续2个符号或连续3个符号,PDCCH在每个时隙中的起始位置是基站通过信令指示。coreset在时域上最多占用3个符号,如果使用LTE-A***的比特位图方式来指示有效子帧或无效子帧(一个子帧包括的符号数为14个),会导致严重的资源浪费。另外,如果按照NR***中的时频域的比特位图方式来指示又会使得信令开销过大,而coreset的结构是相对固定的,没有必要引入过大的灵活性。因此,本申请实施例在LTE***中指示预留资源,该预留资源可以用于NR***的SSB以及coreset,以达到信令开销和资源指示灵活性的最佳优化。
可以理解的是,预留资源除了用于NR***的SSB以及coreset,该预留资源还可以有 其它的预留类型(或者预留方式),例如该预留资源还可以用于NR数据,或者用于超高可靠超低时延通信(ultra reliable low latency communication,uRLLC)数据,此处只是对预留资源的预留类型的举例,不作为对本申请实施例的限定。
例如第一通信设备可以是前述的终端设备,第二通信设备可以是前述的网络设备。第二通信设备可以向第一通信设备发送第一信息,第一信息用于指示第一资源图样以及指示通过第一资源图样确定的第一资源,第一通信设备接收第一信息,第一通信设备根据该第一信息确定出第一资源。其中,第一资源是如下资源类型的至少一种:预留资源,或者可用资源,或者不可用资源,或者需要速率匹配的资源,或者需要打孔的资源,或者需要丢弃的资源,其中,预留资源是指第二通信设备预留的且第一通信设备不可用的资源,可用资源也就是非预留资源,可用资源是第二通信设备指示给第一通信设备、且第一通信设备可使用的资源,需要速率匹配的资源是指示用户需要围绕该资源进行速率匹配(rate matchign),即在计算传输资源时不将该资源计算在内,映射时也不将符号应设在该资源上。需要打孔的资源是将该资源承载的符号打掉不传输,打孔与丢弃(drop)的含义类似。接下来以第一资源为预留资源进行示例说明,首先请参阅图2所示,为本申请实施例提供的第一通信设备和第二通信设备之间的交互流程示意图,本申请实施例提供的资源的指示方法,后续步骤201至步骤203从第二通信设备一侧进行详细说明,后续步骤211至步骤213从第一通信设备一侧进行说明,主要包括如下步骤:
201、第二通信设备确定预留资源,预留资源为第二通信设备指示给第一通信设备不可使用的资源。
在本申请实施例中,第二通信设备首先确定预留资源,其中,第二通信设备将第一通信设备不可使用的资源确定为预留资源,预留资源可以是N个资源集合中的一个或多个资源集合包括的资源,例如预留资源可以通过资源集合对应的位置来确定,该位置也可以称为候选位置,例如资源集合对应的位置可以包括候选起始时间和/或候选频率位置。
本申请实施例中,一个资源集合中包括一个或多个资源单元,该资源单元包括时间单元,例如时间单元可以是符号、时隙、子帧、帧等,该资源单元还可以包括频域单元,例如频域单元可以是子载波、资源块、窄带等,具体可以根据应用场景确定资源单元的实现方式。
202、第二通信设备确定第一信息,其中,第一信息用于指示第一资源图样以及指示通过第一资源图样确定的预留资源,第一资源图样用于确定N个资源集合中每个资源集合对应的位置,N为大于或等于1的正整数。
在本申请实施例中,第二通信设备在确定出预留资源之后,第二通信设备可以确定第一信息,使用该第一信息指示第一资源图样,还可以使用第一信息指示通过第一资源图样确定的预留资源,例如第一信息可以包括是一个信息,例如第一信息可以通过下行控制信令发送,该第一信息也可以通过高层信令发送,第一信息中包括有一个或多个字段,通过第一信息中包括的字段指示第一资源图样以及指示通过第一资源图样确定的预留资源。又如第一信息具体可以指的是多个指示信息,多个指示信息可以通过同一个信息发送,也可以通过不同的信息发送,例如一个指示信息通过高层信令发送,另一个指示信息通过下行控制信息发送。多个指示信息可以指示第一资源图样,还指示通过第一资源图样确定的预 留资源,通过多个指示信息的联合指示,可以使得第一通信设备确定第一资源图样以及指示通过第一资源图样确定的预留资源。例如,第一信息为两个指示信息,第一指示信息指示第一资源图样,第二指示信息指示在第一资源图样中需要预留的资源。第一指示信息和第二指示可以通过相同的信息或信令发送,也可以通过不同的信息或信令发送,如第一指示信息通过高层信令发送,第二指示信息通过下行控制信息发送,或者第一指示信息和第二指示信息都通过下行控制信息发送,或者第一指示信息和第二指示信息是通过高层信令的不同信息发送的,或者第一指示信息和第二指示信息是通过高层信令的相同指示信息发送的。
在本申请实施例中,资源图样可用于确定资源集合对应的位置,该位置可以包括:候选时间位置,和/或频率位置,资源图样在不同场景下可以用于确定具体的资源集合对应的位置,例如,资源图样可以是caseA、caseB和caseC,caseA是针对子载波间隔为15KHz场景,caseB和caseC是针对子载波间隔为30kHz的场景,但是caseB和case C为两个不同的图样(pattern)。在本申请实施例中,第一信息可以指示第一资源图样,该第一资源图样用于确定N个资源集合中每个资源集合对应的位置,N为大于或等于1的正整数,即第一资源图样可以用于确定一个多或多个资源集合中每个资源集合对应的位置。
在本申请的一些实施例中,第一信息用于指示在第一时间段内的第一资源图样以及指示通过第一资源图样确定的预留资源,示例性的,第一时间段为半个子帧。另外,本申请实施例中资源集合对应的位置可以称为候选位置,候选位置包括:候选起始时间和候选频率位置。例如,位置可以是指每个资源集合的第一个符号的编号,示例性的,编号为0的符号是半帧里面的第一个符号。
203、第二通信设备向第一通信设备发送第一信息。
在本申请实施例中,第二通信设备通过前述步骤201确定了预留资源,通过前述步骤202确定了第一信息,然后第二通信设备向第一通信设备发送第一信息,该第一信息可以用于指示第一资源图样以及指示通过第一资源图样确定的预留资源,对于第一信息的指示方式,详见后述内容对第一信息的详细说明。
在本申请的一些实施例中,第一信息,包括:第一指示信息和第二指示信息,其中,
第一指示信息用于指示第一资源图样;
第二指示信息用于在第一资源图样指示的N个资源集合中指示预留资源。
其中,第二通信设备可以获取到第一指示信息和第二指示信息,第一指示信息具有如下指示功能:指示第一资源图样,第二指示信息具有如下指示功能:在第一资源图样指示的N个资源集合中指示预留资源。例如,第一指示信息中携带有第一资源图样,则根据第一指示信息携带的第一资源图样,第一通信设备可以确定出第一资源图样,该第二指示信息指示在第一资源图样指示的N个资源集合中指示预留资源,则指示第一通信设备在第一资源图样指示的N个资源集合中确定出第二通信设备配置的预留资源。例如第一指示信息和第二指示信息可以通过不同的信令来传输,或者第一指示信息和第二指示信息通过同一个信令来传输,此处不做限定。
在本申请的一些实施例中,第一信息还包括如下信息的一种或多种:周期信息、偏移信息和子载波间隔信息,其中,
周期信息用于指示第一资源图样对应的周期值;
偏移信息用于指示每个资源集合对应的位置的偏移值;
子载波间隔信息用于指示每个资源集合对应的子载波间隔。
其中,周期信息、偏移信息和子载波间隔信息,可以与前述的第一指示信息、第二指示信息相互独立,即周期信息、偏移信息和子载波间隔信息与前述的第一指示信息、第二指示信息通过不同的信息进行传输。
周期信息用于指示预留资源对应的资源图样适用的周期,可选的,该周期可以为两个周期信息,分别适用不同的资源预留情况,例如对于SSB和coreset可以分别采用不同的周期值。
偏移信息用于指示每个资源集合对应的位置的偏移值或第一资源图样的偏移量,例如偏移信息指示候选起始时间位置的偏移值。通过偏移信息指示每个资源集合对应的位置的偏移值,可以解决LTE-A***和NR***因子帧边界不对齐而导致的偏移问题,实现预留资源的精确配置。例如,偏移信息指示第一偏移值,则第一偏移值可以是预留资源的第一个符号编号的偏移值,该第一偏移值按照第一单位指示预留资源的第一个符号编号的偏移值,第一单位包括符号,子帧,时隙,帧等。例如第一偏移值指示的偏移值为x个符号,则预留资源第一个符号编号为:mod({2,8}+14n+x,70),n=0,1,2,3,或者,n=0,1。其中,mod(a,b)是取模运算,结果为a除以b的余数。又如,预留资源第一个符号编号为:mod({2,4,8,10}+14n+x,70),n=0,或者,n=0,1。又如,预留资源第一个符号编号为:mod({1,4}+7n+x,70),n=0,1,或者,n=0,1,2,3。需要说明的是,编号0的符号是一个半帧中第一个子帧或第一个slot的第一个符号。
子载波间隔信息可指示子载波间隔为15kHz或为30kHz,例如该子载波间隔信息为1比特,第一状态(如0)指示子载波间隔为15kHz,第二状态(如1)指示子载波间隔为30kHz。可选的,该子载波间隔为NR***的子载波间隔。
211、第一通信设备接收第二通信设备发送的第一信息,其中,第一信息用于指示第一资源图样以及指示通过第一资源图样确定的预留资源,第一资源图样用于确定N个资源集合中每个资源集合对应的位置,N为大于或等于1的正整数。
在本申请实施例中,第一通信设备和第二通信设备可以进行相互通信,例如第一通信设备可以接收第二通信设备发送的第一信息,例如第一信息可以包括是一个信息,例如第一信息可以是下行控制信令,第一信息中包括有一个或多个字段,通过第一信息中包括的字段指示第一资源图样以及指示通过第一资源图样确定的预留资源。又如第一信息具体可以指的是多个指示信息,则多个指示信息可以指示第一资源图样,还指示通过第一资源图样确定的预留资源,通过多个指示信息的联合指示,可以使得第一通信设备确定第一资源图样以及指示通过第一资源图样确定的预留资源。
在本申请实施例中,第一信息还可以指示预留资源,或第一信息还可以通过第一资源图样指示预留资源,例如指示N个资源集合是否有预留资源,例如比特位图为1表示有预留资源,若比特位图为0表示没有预留资源。另外,可选的,指示第一资源图样的可以是前述的第一指示信息,采用比特位图指示是否有预留资源的可以是前述的第二指示信息。
在本申请实施例中,资源图样可用于确定资源集合对应的位置,该位置可以包括:候 选时间位置,和/或频率位置,资源图样在不同场景下可以用于确定具体的资源集合对应的位置,例如,资源图样可以是caseA、caseB和caseC,caseA是针对子载波间隔为15KHz场景,caseB和caseC是针对子载波间隔为30kHz的场景,但是caseB和case C为两个不同的图样(pattern)。在本申请实施例中,第一信息可以指示第一资源图样,该第一资源图样用于确定N个资源集合中每个资源集合对应的位置,N为大于或等于1的正整数,即第一资源图样可以用于确定一个多或多个资源集合中每个资源集合对应的位置。
在本申请的一些实施例中,第一信息可以有至少两个状态,分别为第一状态和第二状态,则第一信息通过不同的状态来指示第一资源图样对应的不同位置。例如第一信息指示第一状态时,第一资源图样指示N个资源集合对应的第一位置,第一信息指示第二状态时,第一资源图样指示N个资源集合对应的第二位置。其中,第一位置和第二位置是指在资源集合中的不同位置。例如第一信息的比特数为M,M为大于或等于0的整数。例如M=1,第一状态(如0)指示预留资源为第一资源图样对应的第一位置(如case B),第二状态(如1)指示预留资源为第一资源图样对应的第二位置(如case C)。本申请实施例中通过第一信息的不同状态,从而可以确定出第一资源图样对应的不同位置,通过指示或定义不同的资源图样确定了预留资源的不同位置,精确的定义和指示了需要预留资源的位置,避免了会使用相同的资源集合的同一个位置导致的冲突问题。
在本申请的一些实施例中,第一信息可以有至少三个状态,分别为第三状态、第四状态和第五状态,则第一信息通过不同的状态来指示第一资源图样对应的不同位置。例如第一信息指示第三状态时,第一资源图样指示N个资源集合对应的第一位置;第一信息指示第四状态时,第一资源图样指示N个资源集合对应的第二位置;第一信息指示第五状态时,第一资源图样指示N个资源集合对应的第三位置。其中,第一位置、第二位置和第三位置是指在资源集合中的不同位置。例如第一信息的比特数为M,M为大于或等于0的整数。例如M=2,第三状态(如00)指示预留资源为第一资源图样对应的第一位置(如case B),第四状态(如01)指示预留资源为第一资源图样对应的第二位置(如case C),第五状态(如10)指示预留资源为第一资源图样对应的第三位置(如case A)。本申请实施例中通过第一信息的不同状态,从而可以确定出第一资源图样对应的不同位置,通过指示或定义不同的资源图样确定了预留资源的不同位置,精确的定义和指示了需要预留资源的位置,避免了会使用相同的资源集合的同一个位置导致的冲突问题。
进一步的,在本申请的一些实施例中,当第一信息占用两个比特时,第一信息还可以指示第六状态,第一信息指示第六状态时,第一资源图样指示N个资源集合中不存在预留资源。即第一信息指示第六状态时,第一资源图样指示没有预留资源。即对于第一通信设备而言,可以使用该资源进行信号传输。通过第一信息指示的不同状态可以实现对是否存在预留资源的指示,使得第一通信设备可以确定是否使用第二通信设备指示的资源。

本申请实施例还提供另一种资源指示方法,主要包括如下流程:
第二通信设备确定预留资源,所述预留资源为所述第二通信设备指示给第一通信设备不可使用的资源或需要打孔(puncture)或丢弃(drop)的资源或需要速率匹配的资源;
所述第二通信设备确定第一信息,其中,所述第一信息用于指示第一资源图样以及指 示通过所述第一资源图样确定的所述预留资源,所述第一资源图样用于确定N个资源集合中每个资源集合对应的位置,所述N为大于或等于1的正整数;
所述第二通信设备向所述第一通信设备发送所述第一信息。
第一通信设备接收第二通信设备发送的第一信息,其中,所述第一信息用于指示第一资源图样以及指示通过所述第一资源图样确定的预留资源,所述第一资源图样用于确定N个资源集合中每个资源集合对应的位置,所述N为大于或等于1的正整数;
所述第一通信设备根据所述第一资源图样指示的N个资源集合对应的位置确定预留资源,所述预留资源是所述第一通信设备不可使用的资源;
所述第一通信设备确定不通过所述预留资源传输信号。
其中,所述第一信息包括:第五指示信息,所述第五指示信息用于指示承载所述第一资源的子载波的个数;和/或,指示承载所述第一资源的子载波位于子载波序列的最大端或者最小端。
其中,第二通信设备发送的第五指示信息用于指示需要打孔的子载波位于子载波编号的小端或者大端,或者指示需要丢弃的子载波位于子载波编号的小端或者大端,或者指示需要速率匹配的子载波位于子载波编号的小端或者大端。又如,第二通信设备发送的第五指示信息用于指示需要打孔的子载波位于资源块(RB)编号的小端或者大端,或者指示需要丢弃的子载波位于资源块(RB)编号的小端或者大端,或者指示需要速率匹配的子载波位于资源块(RB)编号的小端或者大端。上述的小端指的是按照编号从小到大排序时编号较小的一侧,例如小端可以是最小端,即编号最小。上述的大端指的是按照编号从大到小排序时编号较大的一侧,例如大端可以是最大端,即编号最大。
本申请实施例中,第五指示信息还可以指示需要打孔(puncture)或丢弃(drop)或速率匹配的子载波数。例如,若第五指示信息取值为0,指示预留资源在子载波编号小的一侧,若第五指示信息的取值为1,表示预留资源在子载波编号大的一侧。示例性的,1比特信息指示需要打孔或丢弃或速率匹配的子载波位于子载波编号或RB编号最大或大端还是在编号最小端。比如使用2比特,00表示在需要打孔或丢弃或速率匹配的子载波在编号小的一段,且子载波个数为1,01表示在需要打孔或丢弃或速率匹配的子载波在编号(最)小的一端,且子载波个数为2,10表示在需要打孔或丢弃或速率匹配的子载波在编号(最)大的一端,且子载波个数为1,11表示在需要打孔或丢弃或速率匹配的子载波在编号(最)大的一端,且子载波个数为2。
可以理解的是,本申请实施例中,第二通信设备向第一通信设备发送第五指示信息,第一通信设备根据第五指示信息确定子载波编号最小的N个子载波需要打孔或丢弃或速率匹配,或者子载波编号最大的N个子载波需要打孔或丢弃或速率匹配。即第五指示信息指示了两个内容,一个是需要打孔或丢弃或速率匹配的子载波位置,另外一个是需要打孔或丢弃或速率匹配的子载波数目。
另外,最大端和最小端也可以理解为指示需要打孔或丢弃或速率匹配的子载波为编号为0,1,…N-1,或M-1,M-2,…M-N,其中N为需要打孔或丢弃或速率匹配的子载波个数,M为***带宽中包括的子载波个数,或窄带中包括的子载波个数。
212、第一通信设备根据第一资源图样指示的N个资源集合对应的位置确定预留资源, 预留资源是第一通信设备不可使用的资源。
在本申请实施例中,第一通信设备接收到该第一信息之后,第一通信设备可以解析该第一信息,确定出第一信息指示的第一资源图样,并且进一步的确定出第一资源图样,以及确定该第一资源图样指示的N个资源集合对应的位置,通过第一资源图样指示的N个资源集合对应的位置确定出第二通信设备配置的预留资源,则第一通信设备不能使用该预留资源,对于第一信息的指示方式,详见前述内容对第一信息的详细说明。
213、第一通信设备确定不通过预留资源传输信号。
在本申请实施例中,第一通信设备在确定出第二通信设备指示的预留资源之后,第一通信设备可以确定不能使用该预留资源传输信号,其中,该信号包括如下信号的一种或多种:物理上行信道,物理下行信道,参考信号,物理上行控制信道,物理下行控制信道,小区参考信号,探测(sounding)参考信号,解调参考信号。

在本申请的一些实施例中,第一信息还用于指示预留资源用于同步信号块或者控制资源集。即预留资源的预留方式(或者类型)可以是用于同步信号块,或者用于控制资源集。
在本申请的一些实施例中,第一信息指示第三状态时,第一资源图样指示第一资源预留类型、且指示N个资源集合对应的第一位置;
第一信息指示第四状态时,第一资源图样指示第一资源预留类型、且指示N个资源集合对应的第二位置;
第一信息指示第五状态时,第一资源图样指示第二资源预留类型;
第一信息指示第六状态时,第一资源图样指示N个资源集合中不存在预留资源。
其中,第一资源预留类型可以是用于同步信号块,第二资源预留类型可以是用于控制信号集。例如,第一资源图样指示N个资源集合对应的第一位置时,第一资源图样可以是前述的caseB。第一资源图样指示N个资源集合对应的第二位置时,第一资源图样可以是前述的caseC。
在本申请的一些实施例中,第一信息指示第三状态时,第一资源图样指示第一资源预留类型、且指示N个资源集合对应的第一位置;

第一信息指示第五状态时,第一资源图样指示第二资源预留类型;
第一信息指示第六状态时,第一资源图样指示第一资源预留类型、且指示N个资源集合对应的第三位置。

通过前述实施例的举例说明可知,在本申请实施例中,第二通信设备在确定出预留资源之后,第二通信设备可以获取第一信息,使用该第一信息指示第一资源图样,还可以使用第一信息指示通过第一资源图样确定的预留资源,第二通信设备向第一通信设备发送该第一信息,可以使得第一通信设备确定第一资源图样以及指示通过第一资源图样确定的预留资源,最后第一通信设备可以不通过预留资源传输信号。本申请实施例中第二通信设备发送的第一信息指示了第一资源图样,还通过该第一资源图样指示的N个资源集合对应的位置确定预留资源,本申请实施例中针对资源图样进行指示,可以减少资源浪费,且减少指示资源时的信令开销。

通过本申请实施例的方案可以有效的避免与SSB和coreset的资源冲突,同时根据SSB和coreset的特点指示其预留资源类型,相比于时域比特位图方式节省了信令开销,预留资源颗粒度为符号级别,避免了资源的浪费。
LTE-A***的比特位图方式指示有效子帧或无效子帧(一个子帧包括的符号数为14个),本申请实施例中指示SSB或coreset的资源图样,是符号级别的资源预留。
NR***的时频域的比特位图方式,而本申请实施例中结合了SSB和coreset的资源图样设计信令,指示不同的资源图样,而资源图样数远远小于时域符号数,极大地节约了信令开销。
本申请实施例中使用比特位图指示SSB的8个候选位置是否有SSB,同时指示NR***所使用的子载波间隔以及当子载波间隔为30kHz时SSB的资源图样是case B还是case C。本申请实施例是符号级别的资源预留,进一步节约了资源。
本申请实施例中,指示或定义了不同的场景时,预留资源的不同资源图样。由于NR和LTE的SCS可能是不同的,且帧边界有可能是不对齐的,通过指示或定义不同的资源图样可以确定了SSB的预留资源的位置,精确的定义和指示了需要预留资源的位置,避免了LTE和SSB的碰撞问题。
本申请实施例中,网络设备可以指示预留资源的用途是SSB或者corset。用于区分不同的指示信令,避免信令的混淆和浪费。
本申请实施例中对于coreset指示需要预留的符号数、一个子帧内的起始位置以及周期。本申请实施例中采用的是符号级资源预留,节省资源。
