Abstract
本申请提供一种通信方法和装置,该方法包括:第一设备从第二设备接收第一信息,所述第一信息用于所述第一设备确定是否能够使用第一资源传输信号,所述第一资源为所述第二设备为所述第一设备配置的多个资源中的一个;所述第一设备根据所述第一信息,确定使用所述第一资源;所述第一设备通过所述第一资源向所述第二设备发送信号。本申请提供的通信方法和装置不仅可以降低第一设备的功耗,而且可以避免资源的浪费和资源的碰撞。
Description
本申请涉及通信技术领域,尤其涉及一种通信方法和装置。
在通信系统中,为了降低资源开销,达到降低数据传输时延和节能的目的,可以在预先定义好的资源上传输业务,也即预配置资源(preconfigured uplink resource transmission,PUR)传输。其中,预配置资源传输可以在连接态(connected mode)进行传输,也可以在空闲态(idle mode)进行传输。
现有技术中,网络设备会预先为终端设备配置PUR,该终端设备通过网络设备配置的PUR进行信号的传输。其中,一个PUR能够传输的传输块的尺寸的最大值是受限制的,也就是终端设备不能够传输过大的传输块。当终端设备待传输数据较多时,一次PUR传输不能够完全传输完终端设备的所有信息,此时,一种方式是终端设备进入连接态,以进一步传输剩余的数据,另外一种方式是网络设备为终端设备配置多个PUR。
然而,上述的方式中,当终端设备进入连接态,并将剩余的数据传输完成之后,网络设备需要释放无线资源控制(Radio Resource Control,RRC)连接,将终端设备重新释放到空闲态,整个过程延时较长,终端设备需要监测额外的控制信道接收相应信令,导致终端设备的功耗较高。另外,在终端设备进入连接态传输数据时,终端设备仍然需要下行控制信息(downlink control information,DCI)调度PUR,因此,终端设备需要不断监测调度的DCI,造成终端设备的功耗较高。而配置多个PUR的方式,对于其他的终端设备,将不能使用这些PUR进行信号传输,由于终端设备的数据量是波动的,当数据里较少时,会造成严重的资源浪费。

下面首先针对本申请实施例适用场景进行简要说明。
终端设备在通过网络设备配置的PUR进行信号传输时,一个PUR能够传输的传输块的最大值是受限制的,也就是终端设备不能够通过一个PUR传输过大的传输块。当终端设备的待传输数据较多时,一次PUR传输不能够完全传输完终端设备的所有信息,此时,一种方式是终端设备进入连接态,以进一步传输剩余的数据,另外一种方式是网络设备为终端设备配置多个PUR。当终端设备进入连接态,并将剩余的数据传输完成之后,网络设备需要释放RRC连接,将终端设备重新释放到空闲态,整个过程延时较长,终端设备需要监测额外的控制信道接收相应信令,导致终端设备的功耗较高。另外,在终端设备进入连接态传输数据时,终端设备仍然需要DCI调度PUR,因此,终端设备需要不断监测调度的DCI,造成终端设备的功耗较高。而配置多个PUR 的方式,对于其他的终端设备,将不能使用这些PUR进行信号传输,如果终端设备的数据量较少,那么会造成严重的资源浪费。
本申请实施例中考虑到上述问题,提出了一种通信方法,第二设备确定第一信息后,将第一信息发送给第一设备,其中,第一信息用于第一设备确定是否能够使用第一资源传输信号,该第一资源为第二设备为第一设备配置的多个资源中的一个,第一设备根据该第一信息,确定使用第一资源,然后通过第一资源向第二设备发送信号。由于第二设备可以为第一设备配置多个资源,第一设备在通过第二设备发送的第一信息,确定能够使用第一资源传输信号时,将通过第一资源向第二设备发送未传输完的信号,由此可以避免现有技术中第一设备需要进入连接态继续传输剩余信号的现象,由此可以降低第一设备的功耗。另外,由于第一设备是根据第二设备的指示通过预配置资源进行信号的传输,因此,其他终端设备也可以使用第二设备配置的预配置资源,从而不仅可以避免资源的浪费,而且可以避免资源的碰撞。
本申请实施例还提出一种通信方法,第二设备确定第八信息后,将第八信息发送给第一设备,第一设备根据该第八信息的加扰方式,确定是否能够使用第一资源传输信号,该第一资源为第二设备为第一设备配置的多个资源中的一个,第一设备确定使用第一资源,则通过第一资源向第二设备发送信号。示例性的,第八信息用于指示第二资源的传输状态,传输状态可以理解为第一设备在第二资源上传输的信号的传输状态,该传输状态包括传输成功和/或传输失败,也可以理解为确认应答ACK(Acknowledge)和/或否定应答NACK(Negative Acknowledgment)。第二资源为第二设备为第一设备配置的多个资源中的一个,第一资源和第二资源是不同的资源。由于第二设备可以为第一设备配置多个资源,第一设备在通过第二设备发送的第八信息,确定能够使用第一资源传输信号时,将通过第一资源向第二设备发送未传输完的信号,由此可以避免现有技术中第一设备需要进入连接态继续传输剩余信号的现象,由此可以降低第一设备的功耗。另外,由于第一设备是根据第二设备的指示通过资源进行信号的传输,因此,其他终端设备也可以使用第二设备配置的资源,从而不仅可以避免资源的浪费,而且可以避免资源的碰撞。
下面,通过具体实施例对本申请的技术方案进行详细说明。需要说明的是,下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图2为本申请通信方法的一种信令交互图。本实施例以通信系统中的第一设备和第二设备之间的信息交互进行说明。在上述图1所示系统架构的基础上,如图2所示,在本实施例中,该通信方法可以包括如下步骤:
步骤201:第二设备确定第一信息。
其中,第一信息用于指示第一设备是否能够使用第一资源传输信号,第一设备是否能够使用第一资源传输信号,可以理解为第一资源是否处于激活状态,也可以理解为第一资源是否处于使能状态。
该第一资源为第二设备为第一设备配置的多个资源中的一个,示例性的,该多个资源为预配置资源(preconfigured uplink resource transmission,PUR)。
在本步骤中,第一设备向第二设备发送信号时,第二设备会为第一设备配置多个 资源,示例性的,该多个资源为PUR,其中,第一资源为多个预配置资源中的一个。示例性的,第一资源为PUR资源。
值得注意的是,PUR仅是一种示例性命名,其实质是第二设备通过配置第一资源,第一设备可以在不需要第二设备动态调度或下行控制信息调度的情况下在第一资源上进行上行信息的传输,该资源也可以命名为其他名称,如配置授权资源。应理解,若该配置授权资源也可以实现本申请实施例中的第一资源所实现的功能,也可以将配置授权资源理解为本申请实施例中的第一资源。为了描述方便,本申请实施例中将第一资源统一称为预配置上行链路资源。
另外,预配置资源传输,可以指第一设备在预配置上行链路资源按照预先规定的参数进行数据传输。本申请实施例中“预配置资源传输”也可以称为“预配置传输方式”、“免调度传输”、“预配置资源传输”、“预配置资源免调度传输”等。应理解,本申请实施例中“预配置资源传输”仅是一种示例性说明,在实际应用中,也可以将“预配置资源传输”命名为其他名称,若该其他名称也可以实现本申请实施中“预配置资源传输”的功能,都可以理解为按照预配置资源传输的方式进行上行信号传输。为了描述方便,本申请实施例中将该传输方式统一称为预配置资源传输。
需要说明的是,多个预配置资源可以使用相同传输配置信息或使用不同的传输配置信息,其中,传输配置信息包括以下信息中的一种或多种:定时提前(timing advance,TA)信息、功率控制信息、编码调制(Modulation and coding scheme,MCS)和重复次数。
示例性的,第二设备确定第一信息之前,第二设备会从第一设备接收通过第二资源发送的信号,其中,第二资源为多个资源中的一个,示例性的,该多个资源为预配置资源,第二资源与第一资源不同。示例性的,第二资源为PUR资源。
具体地,第二资源为第二设备为第一设备配置的多个资源中的一个,示例性的,该多个资源为预配置资源中的一个,且第二资源是与第一资源不同的资源,其中,第二资源与第一资源不同,可以理解为第二资源的时间和第一资源的时间不同,也可以理解为第二资源和第一资源的频率不同。在一种可能的实现方式中,第二资源可以为默认激活的资源,或者称为默认可用的资源,或者也可以称为首次可用资源或首次激活资源等,第二资源的本质就是该资源用于预配置资源的第一次传输,也就是在连接态配置PUR资源时就指示该资源可用,不需要第二设备动态指示其是否可用。第一设备可以通过第二资源向第二设备发送信号,由于第二资源能够传输的信号的最大值是受限制的,若第一设备需要发送的数据量很大,在通过第二资源不能够完全传输完第一设备的所有信息时,第一设备还需要通过不同于第二资源的第一资源继续向第二设备发送剩余的信号,也即未传输完的信号。
在一种可能的实现方式中,第一设备还可以向第二设备发送第二信息,第二设备将根据第一设备发送的第二信息,例如,该第二信息用于指示缓存状态报告(Buffer Status Report,BSR),第二设备根据BSR确定第一信息。另外,该第二信息还可以用于指示其他信息,例如用于指示PUR请求信息等,第二设备将根据第一设备发送的第二信息,例如根据PUR请求信息等确定第一信息。
具体地,第一设备会向第二设备发送第二信息,其中,该第二信息可以用于指示 BSR,也可以用于指示RRC连接请求(RRC connection request)或者PUR请求信息等,其中,该第二信息用于向第二设备请求资源。第二设备在接收到第二信息时,将根据第二信息,确定是否激活第一资源或者确定是否使能第一资源,也即确定第一设备是否能够使用第一资源传输信号。若第二设备确定激活第一资源或者确定使能第一资源,则第一设备能够使用第一资源传输信号,若第二设备确定不激活第一资源或者确定不使能第一资源,则第一设备不能够使用第一资源传输信号。
其中,第一设备是否能够使用第一资源传输信号包括第一设备能够使用第一资源传输信号,也可以称为第一资源可用,或者第一设备不能够使用第一资源传输信号,也可以称为第一资源不可用。若第一设备能够使用第一资源传输信号时,第二设备会将第一资源进行激活或者使能,这样,第一设备将会通过激活或者使能的第一资源传输信号。若第一设备不能够使用第一资源传输信号时,第二设备将不会激活或者不会使能第一资源。
在另一种可能的实现方式中,在第二设备接收到第一设备发送的第二信息时,第二设备就会为第一设备保留第一资源,也即在第二设备接收到第一设备发送的第二信息时,该第一资源即为可用状态,第一设备将可以根据该第一资源传输信号。
示例性的,若第一设备不能够使用第一资源传输信号时,该第二设备可以将第一资源配置给其他设备,这样其他设备将可以通过第一资源传输信号,由此可以避免资源的浪费,从而能够节省资源。
值得注意的是,示例性的,若第二设备通过第一信息指示第一设备能够使用第一资源传输信号,也即指示第一资源可用时,则在下一个PUR周期内或者PUR时机(occasion)内,将不存在可用的预配置资源。或者,若第一设备确定出能够使用第一资源传输信号,也即确定出第一资源可用时,则第一设备将不会使用下一个PUR周期或者PUR时机(occasion)内的PUR传输信号。
示例性的,第二设备还会向第一设备发送第七信息,该第七信息用于指示在本周期内是否存在可用的PUR。
具体地,第一设备在通过PUR向第二设备传输信号之前,还会接收第二设备发送的第七信息,以通过该第七信息确定在本周期内是否存在可用的PUR,若存在,则通过可用的PUR向第二设备传输信号。另外,该第七信息可以包含于DCI中,也可以包含于高层信令中。也就是说,第二设备会通过DCI或者高层信令将第七信息发送给第一设备。
在本申请实施例中,高层信令可以是指高层协议层发出的信令,高层协议层为物理层以上的至少一个协议层。其中,高层协议层具体可以包括以下协议层中的至少一个:媒体接入控制(Medium Access Control,MAC)层、无线链路控制(Radio Link Control,RLC)层、分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线资源控制(radio resource control,RRC)层和非接入层(non-access stratum,NAS)等。
图3为预配置资源PUR是否可用的示意图,如图3所示,在第一个周期内,第一设备可以通过PUR0向第二设备发送信号,此时,PUR1不可用,也即第一设备不能够通过PUR1传输信号,在第二个周期内,第一设备通过PUR0向第二设备发送信号后,若信息未传输完,则第一设备会向第二设备上报BSR,此时,第二设备将向第一设备 发送第一信息,指示第一设备可以通过PUR1传输信号,也即PUR1可用。另外,在第三个周期内,将不存在可用的PUR。
由于在第二设备指示第一设备能够使用第一资源传输信号时,第一设备将不会再使用下一个PUR周期或者PUR时机(occasion)内的PUR资源来传输信号,这样,由于第一设备在使用当前PUR周期或者PUR时机(occasion)内的至少两个PUR传输信号后,很大概率上将不会再有信号待传,因此,下一个PUR周期或者PUR时机(occasion)内的PUR可以释放,从而可以减少资源浪费,同时可以有效避免多个PUR和下一个PUR周期或者PUR时机(occasion)的PUR发生冲突的现象。
步骤202:第二设备向第一设备发送第一信息。
在本步骤中,第二设备在确定第一信息后,会将第一信息发送给第一设备。
示例性的,该第一信息可以包含于下行控制信息(Downlink Control Information,DCI)中,也可以包含于高层信令中。也就是说,第二设备会通过DCI或者高层信令将第一信息发送给第一设备。
在本申请实施例中,高层信令可以是指高层协议层发出的信令,高层协议层为物理层以上的至少一个协议层。其中,高层协议层具体可以包括以下协议层中的至少一个:MAC层、RLC层、PDCP层、RRC层和NAS等。
在一种可能的实现方式中,若第一信息包含于DCI中,可以通过该DCI中的k比特指示第一信息,例如k=1,若第一信息为“0”时,可以用于指示第一设备确定不能够使用第一资源传输信号,若第一信息为“1”,则用于指示第一设备确定能够使用第一资源传输信号。也可以在第一信息为“0”时,用于指示第一设备确定能够使用第一资源传输信号,若第一信息为“1”,则用于指示第一设备确定不能够使用第一资源传输信号。当然,也可以用其他方式指示第一设备是否能够使用第一资源传输信号。
例如k=ceil{log
2(N+M)},其中N为配置的PUR的个数,log
2(N+M)表示N+M的以2为底的对数,ceil{x}表示大于或者等于x的最小整数,M为大于或等于0的整数。当N=3,M=1时,k=2,也即第一信息为“00”时,指示第一设备确定不能够使用第一资源传输信号,若第一信息为“01”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为a,若第一信息为“10”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为b,若第一信息为“11”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为c;或者,第一信息为“00”时,指示第一设备确定不能够使用第一资源传输信号,若第一信息为“01”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第一个PUR;若第一信息为“10”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第二个PUR;若第一信息为“11”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第三个PUR。
当N=2,M=2时,k=2,若第一信息为“00”时,指示第一设备确定不能够使用第一资源传输信号,若第一信息为“01”时,指示第一设备进入连接态,若第一信息为“10”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为b;若第一信息为“11”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为c;或者,若第一信息为“00”时,指示 第一设备确定不能够使用第一资源传输信号,若第一信息为“01”时,则用于指示第一设备进入连接态;若第一信息为“10”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第一个PUR;若第一信息为“11”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第二个PUR。
值得注意的是,以上均为一种示例性说明,只要指示内容与本申请实施例中的内容相同,均属于本申请的保护范围。
在另一种可能的实现方式中,若第一信息包含于高层信令中,例如包含于RRC消息或媒体接入控制(media access control,MAC)控制单元(control element,CE)信息中时,可以通过该高层信令中的g比特指示第一信息,例如g=1,若第一信息为“0”时,可以用于指示第一设备确定不能够使用第一资源传输信号,若第一信息为“1”,则用于指示第一设备确定能够使用第一资源传输信号。也可以在第一信息为“0”时,用于指示第一设备确定能够使用第一资源传输信号,若第一信息为“1”,则用于指示第一设备确定不能够使用第一资源传输信号。当然,也可以用其他方式指示第一设备是否能够使用第一资源传输信号。
例如k=ceil{log
2(N+M)},其中N为配置的PUR个数,log
2(N+M)表示N+M的以2为底的对数,ceil{x}表示大于或者等于x的最小整数,M为大于或等于0的整数。当N=3,M=1时,k=2,也即第一信息为“00”时,指示第一设备确定不能够使用第一资源传输信号,若第一信息为“01”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为a,若第一信息为“10”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为b,若第一信息为“11”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为c;或者,第一信息为“00”时,指示第一设备确定不能够使用第一资源传输信号,若第一信息为“01”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第一个PUR;若第一信息为“10”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第二个PUR;若第一信息为“11”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第三个PUR。
当N=2,M=2时,k=2,若第一信息为“00”时,指示第一设备确定不能够使用第一资源传输信号,若第一信息为“01”时,指示第一设备进入连接态,若第一信息为“10”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为b;若第一信息为“11”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源的索引(index)为c;或者,若第一信息为“00”时,指示第一设备确定不能够使用第一资源传输信号,若第一信息为“01”时,则用于指示第一设备进入连接态;若第一信息为“10”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第一个PUR;若第一信息为“11”时,则用于指示第一设备确定能够使用第一资源传输信号,且第一资源为第二个PUR。
值得注意的是,以上均为一种示例性说明,只要指示内容与本申请实施例中的内容相同,均属于本申请的保护范围。
另外,示例性的,上述的DCI或者RRC消息或MAC CE中还包括PUR的配置更新信息。其中,该配置更新信息包括如下一种或多种信息:指示PUR传输是否成功的 指示信息、定时提前(timing advance,TA)信息、功率控制信息、编码调制(modulation and coding scheme,MCS)和重复次数。其中,PUR传输是否成功的指示信息包括传输成功状态或传输失败状态,也可以理解为确认应答(Acknowledge,ACK)或否定应答(Negative Acknowledgment,NACK)。
其中,上述的配置更新信息对第一资源有效,或对第一资源及下一个PUR周期或者PUR时机(occasion)的预配置资源有效,其中,对第一资源有效,也可以理解为该配置更新信息为第一资源的配置更新信息,对第一资源及下一个PUR周期或者PUR时机(occasion)的预配置资源有效,也可以理解为该配置更新信息为第一资源及下一个PUR周期或者PUR时机(occasion)的预配置资源的配置更新信息。或者,指示第一设备可以使用多个PUR传输数据。
由于配置更新信息针对最近的PUR有效,可以最大程度保证配置更新信息的有效性,防止因为时间过长而导致的配置更新信息过期。
步骤203:第一设备根据第一信息,确定使用第一资源。
在本步骤中,第一设备在接收到第二设备发送的第一信息后,将根据第一信息,确定是否使用第一资源进行信号的传输,例如:若第一信息的值为“0”,则第一设备确定不能使用第一资源进行信号的传输,若第一信息的值为“1”,则第一设备确定能够使用第一资源进行信号的传输。或者,若第一信息的值为“0”,则第一设备确定能够使用第一资源进行信号的传输,若第一信息的值为“1”,则第一设备确定不能使用第一资源进行信号的传输。
或者,第一设备也可以根据第一信息,在确定出能够通过第一资源传输信号的同时,还能确定出该第一资源的索引,或者确定出该第一资源是多个预配置资源中的第几个资源。例如:若第一信息为“11”,则第一设备确定出能够使用索引(index)为c的第一资源传输信号。
进一步地,第一设备还会接收第二设备发送的第八信息,该第八信息用于指示PUR传输状态,传输状态包括传输成功状态或传输失败状态,也可以理解为确认应答ACK(Acknowledge)或否定应答NACK(Negative Acknowledgment)。第一设备通过第八信息的加扰方式,确定是否能够使用第一资源传输信号。示例性的,若第八信息是通过第一无线网络临时标识(Radio Network Temporary Identifier,RNTI)加扰的,则第一设备确定能够使用第一资源传输信号,若第八信息是通过第二RNTI加扰的,则第一设备确定不能使用第一资源传输信号,或者,若第八信息是通过第一RNTI加扰的,则第一设备确定不能使用第一资源传输信号,若第八信息是通过第二RNTI加扰的,则第一设备确定能够使用第一资源传输信号。步骤204:第一设备通过第一资源向第二设备发送信号。
在第一设备根据第一信息确定能够使用第一资源时,第一设备将通过第一资源向第二设备发送信号。相应的,第二设备将通过第一资源接收第一设备发送的信号。
需要进行说明的是,第一设备通过第二资源向第二设备发送信号,若通过第二资源将信号没有全部发送完,也即有剩余的信号,第一设备会再通过第一资源继续向第二设备发送剩余的信号,也就是说,第一设备会通过第二设备配置的多个预配置资源中的至少两个资源,向第二设备发送信号。
进一步地,若第一设备根据第一信息确定不使用第一资源传输信号,则发起随机接入或数据早传(early data transmission)。
在一种可能的实现方式中,第一设备还从第二设备接收第三信息,该第三信息用于指示多个资源之间的时间间隔。
具体地,上述多个资源可以为多个预配置资源,该第三信息可以用于指示第一个预配置资源的起始时间以及各个预配置资源之间的时间间隔,这样,第一设备将可以根据第一个预配置资源的起始时间和各个预配置资源之间的时间间隔,确定出每个预配置资源的起始时间。通过这种指示方式,可以节省网络资源。
另外,第一设备还可以从第二设备接收第五信息,该第五信息用于指示多个资源中每个资源的起始时间。具体地,上述多个资源可以为多个预配置资源,第五信息用于指示多个预配置资源中每个预配置资源的起始时间,第二设备可以将每个预配置资源的起始时间指示给第一设备,使得第一设备根据第五信息即可确定每个预配置资源,从而提高了预配置资源确定的效率。
示例性的,该第三信息或第五信息可以包含于DCI中,也可以包含于高层信令中。也就是说,第二设备会通过DCI或者高层信令将第三信息或第五信息发送给第一设备。
在本申请实施例中,高层信令可以是指高层协议层发出的信令,高层协议层为物理层以上的至少一个协议层。其中,高层协议层具体可以包括以下协议层中的至少一个:MAC层、RLC层、PDCP层、RRC层和NAS等。
示例性的,上述多个资源之间的频率资源相同。
具体地,第二设备在通过第三信息指示多个资源之间的时间间隔,或通过第五信息指示每个资源的起始时间,以使第一设备确定资源时,该多个资源之间的频率资源相同。
在另一种可能的实现方式中,第一设备从第二设备接收第四信息,该第四信息用于指示多个资源之间的频率间隔。
具体地,上述多个资源可以为多个预配置资源,该第四信息可以用于指示第一个预配置资源的起始频率以及各个预配置资源之间的频率间隔,这样,第一设备将可以根据第一个预配置资源的起始频率和各个预配置资源之间的频率间隔,确定出每个预配置资源的起始频率。通过这种指示方式,可以节省网络资源。
另外,第一设备还可以从第二设备接收第六信息,该第六信息用于指示多个资源中每个资源的起始频率。具体地,上述多个资源可以为多个预配置资源,该第六信息用于指示多个预配置资源中每个预配置资源的起始频率,第二设备可以将每个预配置资源的起始频率指示给第一设备,使得第一设备根据第六信息即可确定每个预配置资源,从而提高了预配置资源确定的效率。
示例性的,该第四信息或第六信息可以包含于DCI中,也可以包含于高层信令中。也就是说,第二设备会通过DCI或者高层信令将第四信息或第六信息发送给第一设备。
在本申请实施例中,高层信令可以是指高层协议层发出的信令,高层协议层为物理层以上的至少一个协议层。其中,高层协议层具体可以包括以下协议层中的至少一个:MAC层、RLC层、PDCP层、RRC层和NAS等。
第一设备根据多个资源之间的时间间隔或者频率间隔,可以确定出第一资源,从 而可以根据第一资源向第二设备传输信号。
本申请实施例提供一种通信方法,第二设备确定第一信息后,将第一信息发送给第一设备,其中,第一信息用于第一设备确定是否能够使用第一资源传输信号,该第一资源为第二设备为第一设备配置的多个资源中的一个,第一设备根据该第一信息,确定使用第一资源,然后通过第一资源向第二设备发送信号。由于第二设备可以为第一设备配置多个资源,第一设备在通过第二设备发送的第一信息,确定能够使用第一资源传输信号时,将通过第一资源向第二设备发送未传输完的信号,由此可以避免现有技术中第一设备需要进入连接态继续传输剩余信号的现象,由此可以降低第一设备的功耗。另外,由于第一设备是根据第二设备的指示通过资源进行信号的传输,因此,其他终端设备也可以使用第二设备配置的资源,从而不仅可以避免资源的浪费,而且可以避免资源的碰撞。
进一步地,增强型机器类通信(enhanced Machine Type Communication,eMTC)系统及其他演化系统是在长期演进系统(Long Term Evolution,LTE)基础上衍生的系统,它在LTE系统中、并在LTE频段中进行工作。eMTC终端具有低功耗和长休眠等特性,使得eMTC终端电池寿命较长。由于eMTC UE使用寿命较长,所以未来eMTC可能会独立于LTE系统独立部署。在目前LTE系统中,每个子帧的前三个符号是用于传输DCI的,当eMTC独立部署时,这部分资源可以被eMTC终端重新利用进行信息的传输。其中一种应用是将eMTC的下行控制信道(MTC Physical Downlink Control Channel,MPDCCH)的一部分信息拷贝到控制区域,对于普通的时分双工(Time Division Duplexing,TDD)子帧,将子帧中第二个时隙的前k个符号拷贝到控制区域。图4为MPDCCH的映射方式示意图,如图4所示,可以将第二个时隙的前3个符号映射到控制区域的三个符号中。
但是对于TDD特殊子帧而言,其由下行导频时隙(Downlink Pilot Time Slot,DwPTS),保护间隔(guard period,GP)和上行导频时隙(uplink Pilot Time Slot,UpPTS)组成,总长度为1ms,与一个子帧的长度是一样的,因此一个特殊子帧中用于下行传输的符号数是有限的。有时只有一个下行时隙或第二个时隙中只有两三个符号。而一个特殊子帧中,如果包含一个时隙+n个符号时所占用的最少时间如下表1所示:
表1
因此现有技术中将第二个时隙(slot)的前k个符号拷贝到控制区域的方法无法将使用。
为了解决该问题,现有技术中将MPDCCH(dwpts)中的后k个符号拷贝到前面的控制区域中,该方法可以部分解决该问题,但是由于控制区域第一个符号中有小区参考信号(Cell Reference Signal,CRS)需要预留,因此在拷贝过程中,拷贝的第一个MPDCCH的符号需要在CRS的位置打孔,影响性能。另外,将MPDCCH中第二个时隙中的p(p大于或等于0)符号就映射到控制区域中(控制区域包括k个符号,p<k)。会造成没有充分利用控制区域中的资源,造成资源的浪费。
为了解决上述技术问题,本申请实施例中可以采用如下两种方式:
第一种:第一设备接收第一指示信息,第一指示信息用于指示第一区域所占用的符号数k。其中,第一子帧的第二个时隙包括p个下行符号,第一子帧的第二个时隙的前p个下行符号映射到第一区域的前p个符号,第一子帧的第一个时隙中的最后k-p个符号映射到第一区域的第p+1至第k符号中。其中,p是预定义的或根据第一子帧格式或类型确定的。或者,第一子帧的在第一子帧中的编号为7至编号为7+p-1的p个符号映射到第一区域的编号为0至编号为p-1的p个符号,第一子帧的编号为7-k+p至编号为6的k-p个符号映射到第一区域的编号为p至编号为k的k-p个符号中,其中,p和k均为大于或等于0的正整数。
需要进行说明的是,当p小于k时,可以按照上述第一种方式进行符号的映射。
具体地,图5为特殊子帧映射的示意图,如图5所示,对于特殊子帧的映射,将特殊子帧中第二个时隙的前p个符号(p大于或等于0)映射到控制区域的前p个符号中,将特殊子帧中第一个时隙中的最后k-p个符号,或者第一个时隙中第k~k+k-p个符号映射到控制区域的第p~k-p符号中。其中,p和k均大于或等于0。
由于第二个slot的前p个符号与控制区域的前p个符号的CRS位置是一样的,不用进行打孔,由此可以提升解码性能,同时,一个slot的第一个符号和第二个slot的第一个符号的循环前缀(Cyclic Prefix,CP)长度是一致的,因此不用打掉一部分数据,由此可以提升解码性能。
第二种:第一子帧的第二个时隙包括p个下行符号,将第一子帧的第二个时隙的前k个符号映射到第一区域的k个符号中。
需要进行说明的是,当p大于或等于k时,可以按照上述第二种方式进行符号的映射。
具体地,将特殊子帧相邻的前一个下行子帧或后一个下行子帧,或者,在第一集合中的第二下行子帧的第一(或二)个时隙的前k个符号拷贝到第一区域(如控制区域)的k个符号中。其中,前一个下行子帧可以为下行窄带低功耗(Bandwidth reduced Low complexity,BL)/覆盖增强(Coverage Enhancement,CE)子帧。
其中,上述的拷贝也可以理解为映射或者复制,也即将前k个符号拷贝映射或者复制到控制区域的k个符号中。
示例性的,第一集合中包括一个或多个子帧,第一集合为与该特殊子帧在相同子帧块的子帧集合,每个子帧块N
acc或
个连续的子帧组成,每个子帧块的第一个子帧的子帧数(编号后号)为n
abs,1,其满足(n
abs,1-δ)modN
acc=0或
其中,在频分双工(Frequency Division Duplexing,FDD)时,δ=0,i
Δ=0;在TDD时,δ=2,
示例性的,第二个子帧为在第一集合中在该特殊子帧之前的第一个BL/CE下行子帧,或在该特殊子帧之后的第一个BL/CE下行子帧。
示例性的,第一集合也可以是第二设备指示的或配置的,或者是预定义的。
由于将特殊子帧相邻的前一个下行BL/CE子帧或后一个下行子帧,或者,在第一集合中的第二下行子帧的第一(或二)个时隙的前k个符号拷贝到控制区域的k个符号中,由此可以提升解码性能。
示例性的,第一子帧的第一个slot的第m至m+k的符号映射到第一区域。示例性,第一区域为LTE控制区域,或者为第一子帧的前k个符号。示例性的,m=4。
示例性的,第一子帧的第一个slot的编号为m’至编号为m’+k的符号映射到第一区域。示例性,第一区域为LTE控制区域,或者第一子帧的前k个符号。示例性的m’=3。示例性的,该编号m’为在一个子帧内的或slot内的符号编号。
示例性的,第一子帧为特殊子帧。示例性的,第一子帧为特殊子帧配置(Special subframe configuration)1和6,或者第一子帧为特殊子帧配置(Special subframe configuration)1,2,6,7。
第二设备可以通过第九信息指示第一设备不早于于第一资源起始位置之前x个时间单位进行TA验证,或者第二设备可以通过第九信息指示第一设备最早(或最远,或最大)TA验证时间为第一资源起始位置之前x个时间单位,或者第二设备可以通过第九信息指示第一设备在第一资源起始位置之前x个时间单位内完成TA验证,该时间单位可以为子帧,帧,时隙,ms,符号,s或us等,对于时间单位不做具体限定。也可以理解为,第二设备通过第九信息指示了第一时间段,第一设备在该第一时间段内进行TA验证,该时间段起始时间为第一资源起始时间前x个时间单位,终止为第一资源的y个时间单位,其中x>y,其中y可以等于0或大于0。
可选的,x可以为预定义的,第一设备不早于于第一资源起始位置之前x个时间单位进行TA验证,或者第一设备最早(或最远,或最大)TA验证时间为第一资源起始位置之前x个时间单位,或者第一设备在第一资源起始位置之前x个时间单位内完成TA验证,该时间单位可以为子帧,帧,时隙,ms,符号,s或us等,对于时间单位不做具体限定。
