具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
通信系统中,基站通常需要基于控制信息对UE(User Equipment,用户设备)进行调度,其中,该控制信息可以为DCI(Downlink Control Information,下行控制信息),UE在正确接收到基站发送的控制信息时,可以基于该控制信息获取相应的通信数据,而当UE没有正确接收到基站发送的控制信息时,UE就无法获取到该通信数据。为了保证UE对通信数据的正确获取,基站需要确定UE是否正确接收到了控制信息,以在UE没有正确接收到控制信息时进行响应,例如,该响应可以为重传控制信息的响应等。
本公开实施例提供了一种信息传输方法,在该信息传输方法中,UE可以在接收控制信息后向基站发送响应信息,该响应信息可以指示UE是否正确接收到了控制信息,这样,基站在接收到该响应信息后即可确定UE对控制信息的接收情况,从而能够根据该接收情况进行后续响应,以保证UE对通信数据的正确获取。
下面将对本公开实施例所涉及到的实施环境进行说明:如图1所示,本公 开实施例所涉及到的实施环境包括基站10和UE 20,基站10和UE 20可以通过通信网络进行连接,UE 20为基站10所服务的小区中的任一个UE。
图2是根据一示例性实施例示出的一种信息传输方法的流程图,如图2所示,该信息传输方法用于图1所示的UE 20中,该信息传输方法包括以下步骤。
步骤201、UE接收基站通过目标下行资源发送的目标控制信息。
步骤202、UE确定目标上行资源的时频位置。
步骤203、UE根据该时频位置,通过该目标上行资源向基站发送响应信息,该响应信息用于指示UE是否正确接收到了该目标控制信息。
综上所述,本公开实施例提供的信息传输方法,通过UE在对基站发送的目标控制信息进行接收后,在目标上行资源上向基站发送针对该目标控制信息的响应信息,其中,该响应信息可以指示UE是否正确接收到了该目标控制信息,使得基站能够及时地获取UE对目标控制信息的接收情况,从而保证UE对通信数据的正常获取。
图3是根据一示例性实施例示出的一种信息传输方法的流程图,如图3所示,该信息传输方法用于图1所示的基站10中,该信息传输方法包括以下步骤。
步骤301、基站通过目标下行资源向UE发送目标控制信息。
步骤302、基站确定目标上行资源的时频位置。
步骤303、基站根据该时频位置,通过该目标上行资源接收UE发送的响应信息,该响应信息用于指示UE是否正确接收到了该目标控制信息。
综上所述,本公开实施例提供的信息传输方法,通过基站在向UE发送目标控制信息后,接收UE针对该目标控制信息的响应信息,其中,该响应信息可以指示UE是否正确接收到了该目标控制信息,使得基站能够及时地获取UE对目标控制信息的接收情况,从而保证UE对通信数据的正常获取。
图4A是根据一示例性实施例示出的一种信息传输方法的流程图,如图4A所示,该信息传输方法用于图1所示的实施环境中,该信息传输方法包括以下步骤。
步骤401、基站通过目标下行资源向UE发送目标控制信息。
基站可以通过目标下行资源向UE发送目标控制信息,以根据该目标控制信息对UE进行调度,其中,该目标控制信息可以为DCI,该目标下行资源上可以承载有PDCCH(Physical Downlink Control Channel,物理下行控制信道),该目标下行资源在时域上可以为下行符号(英文:symbol)或下行子帧等通信资源。
步骤402、基站确定目标上行资源的时频位置。
该目标上行资源是分配给UE的用于发送响应信息的上行资源,其中,该目标上行资源在时域上可以为上行符号或上行子帧等通信资源,该响应信息可以指示UE是否正确接收到了基站发送的目标控制信息,实际实现时,该响应信息可以为ACK(Acknowledgement,确认)信息或NACK(Negative Acknowledgment,否定性确认)信息等。
在本公开实施例中,基站需要确定该目标上行资源的时频位置,也即是基站需要执行步骤402的技术过程,以在后续步骤中根据该时频位置在目标上行资源上接收UE发送的响应信息。
实际实现时,该目标上行资源的时频位置可以是预先设定(如,该目标上行资源的时频位置可以由通信协议进行规定)的,或者,该目标上行资源的时频位置可以与基站发送该目标控制信息所使用的目标下行资源的时频位置相关,或者,该目标上行资源的时频位置可以由基站自行确定,在最后一种情况下,为了使UE能够确定目标上行资源的时频位置,基站还需要将该自行确定的目标上行资源的时频位置发送至UE。
下面,本公开实施例将对这三种情况下基站确定目标上行资源的时频位置 的技术过程分别进行说明:
第一种情况、目标上行资源的时频位置是预先设定的,在这种情况下,基站可以根据该预先设定确定目标上行资源的时频位置,例如,基站可以根据通信协议的相关规定确定目标上行资源的时频位置。
可选的,基站可以获取预设的第一上行时频位置集合,该第一上行时频位置集合可以包括通信协议规定的用于传输响应信息的至少一个上行时频位置。而后基站可以从该第一上行时频位置集合中确定目标上行时频位置,并将该目标上行时频位置确定为目标上行资源的时频位置。
在一种可能的情况中,通信协议可以规定UE在该第一上行时频位置集合包括的任一个上行时频位置上发送响应信息,例如,如图4B所示,资源A为目标下行资源,资源B、C和D为第一上行时频位置集合包括的上行时频位置所分别对应的上行资源,通信协议可以规定UE在该第一上行时频位置集合包括的任一个上行时频位置上发送响应信息,因此,UE可以在资源C上发送响应信息。在这种情况下,由于基站不能确定UE发送响应信息所使用的上行时频位置,因此,基站可以将第一上行时频位置集合中所有的上行时频位置均确定为目标上行时频位置,并在后续步骤中,依次在该第一上行时频位置集合包括的上行时频位置上接收响应信息,直至接收到该响应信息为止。
在另一种可能的情况中,通信协议可以规定UE在该第一上行时频位置集合中的在时域上距上述目标下行资源的间隔最小的上行时频位置发送响应信息,例如,如图4B所示,资源A为目标下行资源,资源B、C和D为第一上行时频位置集合包括的上行时频位置所分别对应的上行资源,通信协议可以规定UE在该第一上行时频位置集合中的在时域上距上述目标下行资源的间隔最小的上行时频位置传输响应信息,由于资源B在时域上距离资源A的间隔最小,因此,UE可以在资源B上发送响应信息。在这种情况下,基站可以先确定目标下行资源的时频位置,而后基站可以将该第一上行时频位置集合中在时域上距目标下行资源的间隔最小的上行时频位置确定为目标上行时频位置。
第二种情况、目标上行资源的时频位置与目标下行资源的时频位置相关,在这种情况下,基站可以先确定目标下行资源的时频位置,而后根据该目标下行资源的时频位置确定目标上行资源的时频位置。
在一种可能的情况中,基站可以根据目标下行资源的时频位置以及预设的位置绑定规则确定目标上行资源的时频位置。
其中,位置绑定规则可以是通信协议规定的绑定规则,也可以是基站自身配置的绑定规则,在该位置绑定规则为基站配置的绑定规则时,基站还需要通过物理层信令或高层信令向UE发送该位置绑定规则,其中,高层信令可以为RRC(Radio Resource Control,无线资源控制)信令或MAC(Media Access Control,媒体访问控制)信令等。实际实现时,该位置绑定规则可以为函数规则等,本公开实施例对此不作具体限定。
在另一种可能的情况中,基站可以根据UE处理控制信息所需的时长以及目标下行资源的时频位置确定目标上行资源的时频位置。
通常情况下,不同的UE处理控制信息所需的时长不同,这里所谓的“处理”指的是对控制信息进行解析,以确定是否正确接收到了该控制信息。因此,可以根据不同UE对控制信息进行处理所需的时长来对目标上行资源的时频位置进行配置,以保证UE能够在该目标上行资源上发送响应信息。
在这种情况下,为了确定目标上行资源的时频位置,基站可以先确定UE处理控制信息所需的时长,可选的,基站可以在该UE进行随机接入的过程中,接收该UE发送的用于指示该UE处理控制信息所需时长的能力信息,以根据该能力信息确定UE处理控制信息所需的时长。而后,基站可以根据UE处理控制信息所需的时长和目标下行资源的时频位置确定该目标上行资源的时频位置,其中,该目标上行资源的时频位置与目标下行资源的时频位置在时域上的间隔大于或等于UE处理控制信息所需的时长。
在本公开的一个实施例中,基站可以先确定第二上行时频位置集合,该第二上行时频位置集合包括至少一个与目标下行资源的时频位置在时域上的间 隔大于或等于UE处理控制信息所需的时长的上行时频位置,而后基站可以将该第二上行时频位置集合中在时域上距目标下行资源的时频位置的间隔最小的上行时频位置确定为目标上行资源的时频位置。
例如,如图4C所示,符号P、符号Q和符号K为上行符号,符号W为下行符号,其中,符号W为目标下行资源,UE处理控制信息所需的时长为2个符号在时域上的长度,则基站可以将在时域上与符号W的间隔大于或等于2个符号的上行符号Q和K确定为第二上行时频位置集合中的符号,而后,基站可以将符号Q和符号K中在时域上距符号W的间隔最小的符号Q确定为目标上行资源。
第三种情况、目标上行资源的时频位置由基站自行确定,在这种情况下,基站可以将某一上行资源确定为该目标上行资源,而后基站可以将该目标上行资源的时频位置发送至UE,以使UE能够在后续步骤中通过该目标上行资源发送响应信息。
本公开实施例提供了两种基站将目标上行资源的时频位置发送至UE的方法,其中:
第一种方法为:基站在确定了目标上行资源的时频位置后,生成第一时频位置偏移信息,该第一时频位置偏移信息用于指示目标上行资源的时频位置与上述目标下行资源的时频位置在时域上的间隔,而后基站可以通过上述目标控制信息向UE发送该第一时频位置偏移信息,也即是,基站可以将携带有该第一时频位置偏移信息的目标控制信息发送至UE,以使UE根据该第一时频位置偏移信息和目标下行资源的时频位置确定目标上行资源的时频位置。
实际实现时,该第一时频位置偏移信息可以直接指示目标上行资源的时频位置与上述目标下行资源的时频位置在时域上的间隔,也可以间接指示目标上行资源的时频位置与上述目标下行资源的时频位置在时域上的间隔,其中,所谓“间接指示”指的是:该第一时频位置偏移信息可以指示一个索引,该索引是预先定义的时域间隔集合中的某一个时域间隔值的索引。
需要指出的是,该第一时频位置偏移信息位于目标控制信息中固定或是可配置的位置上,并且有固定或是可配置的长度。
第二种方法为:基站在确定了目标上行资源的时频位置后,确定第二时频位置偏移信息,该第二时频位置偏移信息用于指示目标上行资源的时频位置与目标下行资源的时频位置在时域上的间隔,而后基站可以在预设的时频位置偏移信息与加扰序列的对应关系表中查询与该第二时频位置偏移信息对应的目标加扰序列,基站可以基于查询到的该目标加扰序列对目标控制信息进行加扰,例如,基站可以基于该目标加扰序列对目标控制信息的CRC(Cyclic Redundancy Check,循环冗余校验码)进行加扰,以使UE在确定了能够解扰该目标控制信息的目标加扰序列后,根据该目标加扰序列确定第二时频位置偏移信息,并根据该第二时频位置偏移信息和目标下行资源的时频位置确定目标上行资源的时频位置。
步骤403、UE接收基站通过目标下行资源发送的目标控制信息。
UE可以在目标下行资源承载的PDCCH信道上接收该目标控制信息。
步骤404、UE确定目标上行资源的时频位置。
UE在接收了该目标控制信息后,需要确定目标上行资源的时频位置,以在后续步骤中通过该目标上行资源发送针对该目标控制信息的响应信息。
实际实现时,UE可以基于与基站确定目标上行资源的时频位置同理的方式确定该目标上行资源的时频位置,下面本公开实施例仍以上述目标上行资源的时频位置的三种情况对UE确定目标上行资源的时频位置的方式进行说明:
第一种情况、目标上行资源的时频位置是预先设定的,在这种情况下,UE可以根据该预先设定确定目标上行资源的时频位置,例如,UE可以根据通信协议的相关规定确定目标上行资源的时频位置。
可选的,UE可以获取预设的第一上行时频位置集合,而后UE可以从该第一上行时频位置集合中确定目标上行时频位置,并将该目标上行时频位置确定为目标上行资源的时频位置。
在一种可能的情况中,通信协议可以规定UE在该第一上行时频位置集合包括的任一个上行时频位置上发送响应信息,在这种情况下,UE可以将第一上行时频位置集合中的任意一个上行时频位置确定为目标上行时频位置。
在另一种可能的情况中,通信协议可以规定UE在该第一上行时频位置集合中的在时域上距上述目标下行资源的间隔最小的上行时频位置发送响应信息,在这种情况下,UE可以将该第一上行时频位置集合中的在时域上距上述目标下行资源的间隔最小的上行时频位置确定为目标上行时频位置。
第二种情况、目标上行资源的时频位置与目标下行资源的时频位置相关,在这种情况下,UE可以先确定目标下行资源的时频位置,而后根据该目标下行资源的时频位置确定目标上行资源的时频位置。
在一种可能的情况中,UE可以根据目标下行资源的时频位置以及预设的位置绑定规则确定目标上行资源的时频位置。
其中,该位置绑定规则可以是通信协议规定的绑定规则,也可以是基站通过物理层信令或高层信令配置的绑定规则。
在另一种可能的情况中,UE可以根据自身处理控制信息所需的时长以及目标下行资源的时频位置确定目标上行资源的时频位置,其中,该目标上行资源的时频位置与目标下行资源的时频位置在时域上的间隔大于或等于UE处理控制信息所需的时长。
在本公开的一个实施例中,UE可以先确定第二上行时频位置集合,而后UE可以将该第二上行时频位置集合中在时域上距目标下行资源的时频位置的间隔最小的上行时频位置确定为目标上行资源的时频位置。
第三种情况、目标上行资源的时频位置由基站自行确定,在这种情况下,UE可以根据基站的指示确定目标上行资源的时频位置。
可选的,UE可以对接收的目标控制信息进行解析,以得到该目标控制信息携带的第一时频位置偏移信息,而后,UE可以根据该第一时频位置偏移信息和目标下行资源的时频位置确定目标上行资源的时频位置。
或者,UE可以获取预设的加扰序列集合,该加扰序列集合包括至少一个加扰序列,且该至少一个加扰序列记录于上文所述的时频位置偏移信息与加扰序列的对应关系表中。而后,UE可以依次使用加扰序列集合中的加扰序列对目标控制信息进行解扰(例如,UE可以依次使用加扰序列集合中的加扰序列对目标控制信息的CRC进行解扰)直至对目标控制信息成功解扰为止,UE可以将加扰序列集合中能够成功解扰目标控制信息的加扰序列确定为目标加扰序列,并在时频位置偏移信息与加扰序列的对应关系表(该对应关系表可以由基站下发至UE)中查询与该目标加扰序列对应的第二时频位置偏移信息,UE可以根据该第二时频位置偏移信息和目标下行资源的时频位置确定目标上行资源的时频位置。
步骤405、UE通过目标上行资源向基站发送响应信息。
UE在接收该目标控制信息后,可以对该目标控制信息进行处理以确定自身是否正确接收到了该目标控制信息,例如,UE可以对目标控制信息的CRC进行校验以确定自身是否正确接收到了该目标控制信息。而后,UE可以通过目标上行资源向基站发送响应信息,以通知基站UE是否正确接收到了目标控制信息。
步骤406、基站通过目标上行资源接收UE发送的响应信息。
基站接收到该响应信息后,可以根据响应信息进行后续响应,例如,该后续响应可以为在响应信息指示UE没有正确接收到目标控制信息时,重发该目标控制信息。
综上所述,本公开实施例提供的信息传输方法,通过UE在对基站发送的目标控制信息进行接收后,在目标上行资源上向基站发送针对该目标控制信息的响应信息,其中,该响应信息可以指示UE是否正确接收到了该目标控制信息,使得基站能够及时地获取UE对目标控制信息的接收情况,从而保证UE对通信数据的正常获取。
