步骤102:所述第一用户设备确定所述第一数据包中携带所述第一用户设备的身份相关信息。
在接收到第一数据包后,第一用户设备对第一数据包进行解码,获取第一数据包所携带的至少一个用户设备的身份相关信息,第一用户设备可以确定其中是否包括有第一用户设备的身份相关信息。
如果第一用户设备确定第一数据包中携带了第一用户设备的身份相关信息,则继续步骤103。
步骤103:所述第一用户设备根据确定结果接收第二数据包,并根据所述 第二数据包获取所述第一用户设备对应的第一下行信息;否则,所述第一用户设备不对所述第二数据包进行接收;其中,所述第二数据包中携带所述至少一个用户设备的下行信息,且所述第二数据包中的下行信息与所述第一数据包中的用户设备的身份相关信息为一一对应的关系。
本发明实施例中,第二数据包中可以携带至少一个用户设备的DCI,且第一数据包中携带的用户设备的身份相关信息与第二数据包中携带的DCI为一一对应的关系,即,若第一数据包中携带用户设备1的身份相关信息,则第二数据包中可能就会携带用户设备1的DCI,而若第一数据包中没有携带用户设备1的身份相关信息,则第二数据包中也就不会有用户设备1的DCI。
本发明实施例中,如果用户设备的身份相关信息为用户设备的身份标识信息,那么,如果第一数据包中携带用户设备1的身份相关信息,则第二数据包中也就会携带用户设备1的DCI,否则,如果第一数据包中没有携带用户设备1的身份相关信息,则第二数据包中也就不会携带用户设备1的DCI。
而如果用户设备的身份相关信息为第一信息,那么,如果第一数据包中携带用户设备1的身份相关信息,则第二数据包中可能会携带用户设备1的DCI,具体是否携带用户设备1的DCI,还需要在对第二数据包进行处理后才能确认,如果第一数据包中没有携带用户设备1的身份相关信息,则第二数据包中不会携带用户设备1的DCI。
因此,第一用户设备可以首先对第一数据包进行解码,因为第一数据包只携带各用户设备的身份相关信息,相对来说数据量较小,在解码时所需的时间较少,工作量较小。在对第一数据包解码完毕后,第一用户设备即可知道第一数据包中是否携带第一用户设备的身份相关信息,若第一数据包中携带第一用户设备的身份相关信息,则表明第二数据包中可能携带第一用户设备的DCI(本发明实施例中将其称为第一DCI),第一用户设备再对第二数据包进行接收,接收第二数据包后,第一用户设备对第二数据包进行处理,以从中获取第一DCI,本发明实施例中所说的处理可以是指解调、解码等操作。而若第一数据包中没有携带第一用户设备的身份相关信息,则第一用户设备 也就无需再对第二数据包进行接收,因为第二数据包中不会携带第一DCI。
一般来说,第二数据包中由于携带的是用户设备的DCI,因此数据量相对来说比较大,若第一数据包中没有携带第一用户设备的身份相关信息,第一用户设备可以无需再接收第二数据包,这样,第一用户设备无需对每个DCI进行接收,减少了第一用户设备的工作量,节省了第一用户设备的处理时间,也即缩短了第一用户设备接收DCI的时间,提高了第一用户设备接收DCI的效率,也减小了第一用户设备的功耗。
可选的,本发明实施例中,根据第二数据包获取第一用户设备对应的第一下行信息,包括:
第一用户设备根据用户设备的身份相关信息所在的字段与下行信息所在的字段之间的映射关系、以及第一用户设备的身份相关信息在第一数据包中所在的字段,确定第一用户设备对应的第一下行信息在第二数据包中所在的字段为第一字段;
在第一字段中携带第一下行信息时,从第一字段中获取第一下行信息。
本发明实施例中,用户设备的身份相关信息所在的字段与DCI所在的字段在相应的数据包中的位置可以相同。例如请参见图2,图2中间用竖直的虚线间隔开,虚线左边为第一数据包,虚线右边为第二数据包。在第一数据包中,用户设备1的身份相关信息(即图2中的信息1)所在的字段为字段1,用户设备2的身份相关信息(即图2中的信息2)所在的字段为字段2,用户设备3的身份相关信息(即图2中的信息3)所在的字段为字段3,用户设备4的身份相关信息(即图2中的信息4)所在的字段为字段4,用户设备5的身份相关信息(即图2中的信息5)所在的字段为字段5,在第二数据包中,用户设备1的DCI(即图2中的DCI1)所在的字段为字段1,用户设备2的DCI(即图2中的DCI2)所在的字段为字段2,用户设备3的DCI(即图2中的DCI3)所在的字段为字段3,用户设备4的DCI(即图2中的DCI4)所在的字段为字段4,用户设备5的DCI(即图2中的DCI5)所在的字段为字段5。
例如,第一用户设备确定第一用户设备的身份相关信息所在的字段为图2中的字段3,则第一用户设备也就可以确定,若第二数据包中携带第一DCI,则第一DCI在第二数据包中所在的字段为字段3,从而第一用户设备就可以在接收第二数据包后,从第二数据包的字段3中获取第一DCI,以图2为例的话,第一DCI为DCI3。
另外图2中的第一数据包中还可以包括有其他字段,这里不作限制。以及第一数据包和第二数据包中分别都可以包括有CRC(Cyclic Redundancy Check,循环冗余校验码),用于对数据包进行校验。
图2是以第一数据包中包括5个用户设备的身份相关信息、第二数据包中包括相应的5个用户设备的DCI为例,在具体实施过程中,可以根据需要在第一数据包中携带相应数量的用户设备的身份相关信息,同样也可以在第二数据包中携带相应数量的用户设备的DCI,只要第一数据包中的用户设备的身份相关信息与第二数据包中的用户设备的DCI一一对应即可。例如在实际系统中,第一数据包中所包含的用户设备的身份相关信息的数量可以预定义,或者由高层信令配置,或者也可以根据需要携带的用户设备的身份相关信息的数量配置。
或者,本发明实施例中,用户设备的身份相关信息所在的字段与DCI所在的字段在相应的数据包中的位置可以具有特定的映射关系,该映射关系可以存储在第一用户设备中,则第一用户设备在获知第一用户设备的身份相关信息在第一数据包中所在的字段后,若第二数据包中携带第一DCI,则第一用户设备根据该映射关系就可以知道第一DCI在第二数据包中所在的字段(本发明实施例中将该字段称为第一字段),从而可以从第一字段中获取第一DCI。第一用户设备和网络设备都需要提前知道该映射关系。该映射关系可以是用户设备预先设定的,或者也可以是网络设备预先设定的。
可选的,本发明实施例中,若用户设备的身份相关信息为用户设备的身份标识信息;则,在所述第一字段中携带第一下行信息时,从第一字段中获取第一下行信息,还包括:
第一用户设备对第二数据包进行解码,从解码后的第二数据包的第一字段中获取第一下行信息;或
第一用户设备对第一字段进行解码,并从解码后的第一字段中获取所述第一下行信息。
本发明实施例中,若用户设备的身份相关信息为用户设备的身份标识信息,则,只要确定出第一数据包中携带第一用户设备的身份相关信息,也就能确定第二数据包中携带第一DCI。
本发明实施例中,第二数据包可以是一个完整的整体,即第一用户设备需要对整个第二数据包进行解码才能获得第一字段中的第一DCI。
或者,第二数据包也可以由不同的字段组构成,其中每个字段组中包括至少一个字段。这里的字段组,也可以理解为数据包,即一个字段组可以看作是一个小数据包,可以理解为,将第二数据包分成了多个子数据包。则第一用户设备在确定第一DCI在第二数据包中所在的第一字段后,只需对第一字段所在的字段组进行解码(也即对第一字段进行解码)即可,从而进一步减少了第一用户设备的工作量,也提高了DCI接收效率。甚至,如果将一个字段组看作是一个小数据包,第一用户设备在确定第一DCI在第二数据包中所在的第一字段后,只需接收第一字段所在的字段组(也即第一字段)即可,对于其他的字段组都可以拒绝接收,从而减少用户设备接收DCI的时间,进一步提高接收效率以及降低用户设备的功耗。
若将第二数据包分成多个字段组,则第二数据包可以继续按照图2中的格式,例如图2中,第二数据包的字段1和字段2构成第一个字段组,字段3、字段4和字段5构成第二个字段组,CRC(即字段6)构成第三个字段组,相当于第一个字段组和第二个字段组共用一个CRC,这种情况下,CRC所占的比特较少,节省系统资源。这样,无论要对第一个字段组进行解码还是要对第二个字段组进行解码,都涉及到对字段6进行解码校验。
或者,请参见图3,若将第二数据包分成多个字段组,则第二数据包也可以按照图3的格式构成。图3中,第一数据包中包括有三个用户设备的身份 相关信息,分别为用户设备1的身份相关信息(图3中的信息1)、用户设备2的身份相关信息(图3中的信息2)和用户设备3的身份相关信息(图3中的信息3),因图3中继续以第一数据包中共可以包括5个用户设备的身份相关信息为例,因此还有两个字段为缺省字段,即还可以携带另外两个用户设备的身份相关信息,这两个缺省字段分别表示为图3中的缺省信息1和缺省信息2。第二数据包中,字段1和字段2构成第一个字段组,字段3和字段4构成第二个字段组,字段5和字段6构成第三个字段组,其中字段2、字段4和字段6都为CRC,即为每个字段组单独构造了校验位,在进行信道编码时字段组中的信息与校验位一起进行编码,这意味着,用户设备只需对第一字段所在的字段组进行接收、译码、校验处理即可,而无需对整个第二数据包进行接收处理,简化了处理过程。当然,图3中,用户设备的身份相关信息所在的字段和用户设备的DCI所在的字段之间就具有映射关系,第一用户设备都需要提前知道该映射关系。
本发明实施例中,若第一数据包中携带的用户设备的身份相关信息为第一信息,则第一用户设备即使确定解码后的第一数据包中携带第一用户设备对应的第一信息,也只能认为第二数据包中可能会携带第一DCI,因为第一信息不是完整的用户设备的身份相关信息,因此第一用户设备根据第一信息只能进行模糊判断,具体第二数据包中是否携带第一DCI,第一用户设备还需要在获取第二数据包中携带的第二信息后才能确定。
可选的,本发明实施例中,若用户设备的身份相关信息为第一信息;则,在确定第一用户设备对应的第一下行信息在第二数据包中所在的字段为第一字段之后,还包括:
第一用户设备对第二数据包进行解码,从解码后的第二数据包的第一字段中获取第二信息;第二信息为根据用户设备的身份标识信息得到的信息,且第一信息和第二信息构成相应用户设备的身份标识信息,或,第二信息为用户设备的身份标识信息;
至少根据第二信息判断第一字段中携带的下行信息中是否包括与第一用 户设备对应的第一下行信息;
在所述第一字段中携带第一下行信息时,从第一字段中获取第一下行信息,包括:
若第一字段中携带的下行信息中包括与第一用户设备对应的第一下行信息,则从解码后的第一字段中获取第一下行信息。
可选的,本发明实施例中,若用户设备的身份相关信息为第一信息;则,在确定所述第一用户设备对应的第一下行信息在所述第二数据包中所在的字段为第一字段之后,还包括:
所述第一用户设备对所述第一字段进行解码,从解码后的所述第一字段中获取所述第二信息;所述第二信息为根据用户设备的身份标识信息得到的信息,且所述第一信息和所述第二信息构成相应用户设备的身份标识信息,或,所述第二信息为用户设备的身份标识信息;
至少根据所述第二信息判断所述第一字段中携带的下行信息中是否包括与所述第一用户设备对应的所述第一下行信息;
在第一字段中携带第一下行信息时,从第一字段中获取第一下行信息,包括:
若所述第一字段中携带的下行信息中包括与所述第一用户设备对应的所述第一下行信息,则从解码后的所述第一字段中获取所述第一下行信息。
即,若用户设备的身份相关信息为第一信息,那么后续根据解码方式的不同又分为两种解码情况:第一种情况是对第二数据包进行解码,第二种情况是对第一字段进行解码。至于为何要分为这两种解码方式,在前面已经有过描述,因此这里只对这两种解码方式的具体操作进行介绍。
若是第一种解码情况,则第一用户设备对第二数据包整个进行解码,解码后从第一字段中首先获取第二信息,例如,若第一信息是用户设备的身份标识信息中的部分信息,则第二信息就是相应用户设备的身份标识信息中的剩余信息(例如第一信息是用户设备的身份标识信息的前10个比特,则第二信息可以是该用户设备的身份标识信息的剩余比特),再例如,若第一信息是 对用户设备的身份标识信息进行压缩得到的信息,则第二信息可以是用户设备的身份标识信息本身,等等。
若第二信息和第一信息共同构成用户设备的身份标识信息,则第一用户设备获取第二信息后,可以根据第一信息和第二信息判断第一字段中是否携带第一用户设备的第一DCI,此时,若第一信息和第二信息构成的身份标识信息与第一用户设备的身份标识信息一致,则第一用户设备可以确定第一字段中携带第一DCI,而若第一信息和第二信息构成的身份标识信息与第一用户设备的身份标识信息不一致,则第一用户设备可以确定第一字段中没有携带第一DCI。
而若第二信息就是用户设备的身份标识信息本身,则第一用户设备获取第二信息后,可以直接根据第二信息判断第一字段中是否携带第一用户设备的第一DCI,此时,若第二信息与第一用户设备的身份标识信息一致,则第一用户设备可以确定第一字段中携带第一DCI,而若第二信息与第一用户设备的身份标识信息不一致,则第一用户设备可以确定第一字段中没有携带第一DCI。
之后,若判断确定第一字段中携带第一DCI,则可以从解码后的第一字段中获取第一DCI,而若判断确定第一字段中没有携带第一DCI,则可以不再对第二数据包进行处理。
若是第二种解码情况,则第一用户设备对第一字段进行解码,即对第一字段所在的字段组进行解码,解码后从第一字段中首先获取第二信息。
若第二信息和第一信息共同构成用户设备的身份标识信息,则第一用户设备获取第二信息后,可以根据第一信息和第二信息判断第一字段中是否携带第一用户设备的第一DCI,判断方式与前面的描述类似。
而若第二信息就是用户设备的身份标识信息本身,则第一用户设备获取第二信息后,可以直接根据第二信息判断第一字段中是否携带第一用户设备的第一DCI,判断方式与前面的描述类似。
之后,若判断确定第一字段中携带第一DCI,则可以从解码后的第一字 段中获取第一DCI,而若判断确定第一字段中没有携带第一DCI,则可以不再对第二数据包进行处理。
可选的,本发明实施例中,在第一用户设备接收第一数据包之前,还包括:
第一用户设备接收第三数据包,第三数据包用于指示第一数据包中所携带的用户设备的身份相关信息的数量。
本发明实施例中,第一数据包、第二数据包和第三数据包可以构成一个完整的DCI突发,即DCI数据包,因此,第一数据包可以看做是DCI数据包的第一部分,第二数据包和第三数据包可以看做是DCI数据包的第二部分,或者,第三数据包可以看做是DCI数据包的第一部分,第一数据包和第二数据包可以看做是DCI数据包的第二部分。
网络设备在发送时,可以按照第三数据包-第一数据包-第二数据包的顺序进行发送,其中每两个数据包之间的发送间隔可以由协议规定,或者也可以由网络设备自行设定。
例如,若第一用户设备对第三数据包进行解码后确定第一数据包中所携带的用户设备的身份相关信息的数量为0,那么,若第一用户设备还未接收第一数据包和第二数据包,就可以拒绝接收第一数据包和第二数据包,若第一用户设备已接收第一数据包而未接收第二数据包,则可以不对第一数据包进行处理,且可以拒绝接收第二数据包,若第一用户设备还未接收第一数据包和第二数据包,则第一用户设备无需再对第一数据包和第二数据包进行处理,无论是哪种情况,都减少了第一用户设备的工作量。
另外,再考虑一种情况,第一用户设备可能在步骤101发生的同时、步骤101之后、步骤102之前或步骤102之后,已经接收了第二数据包。
即,可选的,本发明实施例中,在步骤101发生的同时、步骤101之后、步骤102之前或步骤102之后,该方法还包括步骤:
第一用户设备接收第二数据包。
网络设备除了向用户设备发送第一数据包之外,还会向用户设备发送第 二数据包。
网络设备向用户设备发送第一数据包和第二数据包,可以是同时发送,或者也可以是先发送第一数据包再发送第二数据包。若是先发送第一数据包再发送第二数据包,则发送间隔可以由协议或系统预先设定,或者也可以由网络设备自行设定。
那么,在这种情况下,提供一种下行信息接收方法,具体请参见图4,所述方法的主要流程描述如下。
步骤401:第一用户设备接收第一数据包,所述第一数据包中携带至少一个用户设备的身份相关信息;
步骤402:所述第一用户设备确定所述第一数据包中携带所述第一用户设备的身份相关信息;
步骤403:所述第一用户设备根据确定结果,通过接收的第二数据包获取所述第一用户设备对应的第一下行信息;否则,所述第一用户设备不对所述第二数据包进行处理;其中,所述第二数据包中携带所述至少一个用户设备的下行信息,且所述第二数据包中的下行信息与所述第一数据包中的用户设备的身份相关信息为一一对应的关系。
其中,步骤401和步骤402的具体实施过程可以参照图1流程中的相应描述。图4流程与图1流程的区别在于:在图4流程中,第一用户设备已经在接收第一数据包的同时、或在接收第一数据包之后接收了第二数据包,即,在第一用户设备确定第一数据包中携带第一用户设备的身份相关信息之后,无需再接收第二数据包,因为第二数据包已经接收了,因此可以直接对第二数据包进行处理。本发明实施例中所说的处理可以是指解调、解码等操作。
那么,如果第一用户设备确定第一数据包中没有携带第一用户设备的身份相关信息,自然就无需对已经接收的第二数据包进行处理,从而,用户设备无需对每个DCI都进行处理,减少了用户设备对DCI的处理时间。
至于图4流程中的其他具体的实施方式,均可以参照图1流程中的相关描述。不同之处在于,在图1流程中考虑是否要接收第二数据包时,图4流 程中考虑的是是否要对已经接收的第二数据包进行处理。
本发明实施例中,第一用户设备首先接收第一数据包,第一用户设备可以确定第一数据包中是否携带第一用户设备的身份相关信息,若有,则第一用户设备再对第二数据包进行处理,如果第二数据包中携带第一用户设备对应的第一下行信息,则第一用户设备就可以从第二数据包中获取第一下行信息,否则第一用户设备就无需对第二数据包进行处理,因为一般来说,第一数据包中携带第一用户设备的身份相关信息,则第二数据包中才可能会携带与该用户设备对应的下行信息,如果第一数据包中没有携带第一用户设备的身份相关信息,那第二数据包中也就不会携带第一用户设备的下行信息,从而第一用户设备也就无需再处理第二数据包,例如下行信息为DCI,用户设备无需对接收的每个DCI进行处理,减少了用户设备的工作量,节省了用户设备的处理时间,降低了用户设备的功耗。
请参见图5,基于同一发明构思,本发明实施例提供一种DCI发送方法,所述方法的主要流程描述如下。
步骤501:网络设备发送第一数据包,所述第一数据包中携带至少一个用户设备的身份相关信息;所述用户设备的身份相关信息用于:用户设备在确定所述第一数据包中携带自身的身份相关信息时,根据确定结果接收第二数据包,并根据所述第二数据包获取所述用户设备对应的第一下行信息;以及
步骤502:所述网络设备发送第二数据包,所述第二数据包中携带所述至少一个用户设备对应的下行信息,且所述第二数据包中的下行信息与所述第一数据包中的用户设备的身份相关信息为一一对应的关系;其中,所述第二数据包中的下行信息与所述第一数据包中的用户设备的身份相关信息之间的对应关系用于:所述用户设备根据所述第一数据包中的所述用户设备的身份相关信息,从所述第二数据包中获取所述用户设备对应的下行信息。
步骤501和步骤502可以同时进行,或者步骤501可以先进行,步骤502后进行。
可选的,本发明实施例中,下行信息例如可以是指DCI,或者也可以是 指其他可能的下行信息。本发明实施例中以下行信息是DCI为例进行说明。
本发明实施例中,用户设备对数据包进行处理,可以是指对数据包进行解调、解码等处理。
可选的,本发明实施例中,
用户设备的身份相关信息为用户设备的身份标识信息;或者
用户设备的身份相关信息为根据用户设备的身份标识信息生成的第一信息。
本发明实施例中,网络设备例如可以是指基站。
网络设备可以将至少一个用户设备的身份相关信息添加到第一数据包中发送给用户设备,具体添加方式可以参考图2或图3。
例如第一用户设备接收到了第一数据包,则第一用户设备通过对第一数据包进行解码就可以获取其中携带的用户设备的身份相关信息,从而第一用户设备可以判断其中是否携带第一用户设备的身份相关信息,若有,则第一用户设备可以确定接收第二数据包,或者,如果第一用户设备已经接收了第二数据包,那么第一用户设备可以继续对第二数据包进行处理,若没有,则第一用户设备也就无需再对第二数据包进行接收或处理,减少第一用户设备的工作量。
网络设备向用户设备发送第一数据包和第二数据包,可以是同时发送,或者也可以是先发送第一数据包再发送第二数据包,即步骤501和步骤502可以同时发生,或者步骤501先发生,步骤502后发生。
网络设备若是先发送第一数据包再发送第二数据包,则发送间隔可以由协议或系统预先设定,或者也可以由网络设备自行设定。
可选的,本发明实施例中,在网络设备发送第一数据包之前,还包括:
所述网络设备发送第三数据包,所述第三数据包用于指示所述第一数据包中所携带的用户设备的身份相关信息的数量。
本发明实施例中,第一数据包和第二数据包可以构成一个完整的DCI突发,即DCI数据包,因此,第一数据包可以看做是DCI数据包的第一部分, 第二数据包可以看做是DCI数据包的第二部分。
或者,本发明实施例中,第一数据包、第二数据包和第三数据包可以构成一个完整的DCI突发,即DCI数据包,因此,第一数据包可以看做是DCI数据包的第一部分,第二数据包和第三数据包可以看做是DCI数据包的第二部分,或者,第三数据包可以看做是DCI数据包的第一部分,第一数据包和第二数据包可以看做是DCI数据包的第二部分。
网络设备在发送时,可以按照第三数据包-第一数据包-第二数据包的顺序进行发送,其中每两个数据包之间的发送间隔可以由协议规定,或者也可以由网络设备自行设定。
图5所示的流程与图1所示的流程为相应的流程,因此图5中一些具体的实施方式可以参考图1中的描述,不多赘述。
以下结合附图介绍本发明实施例中的设备。

需要说明的是,本发明实施例中的设备都是与如前流程中的方法相应的设备,设备的具体工作方式可参照方法部分的描述。
本发明实施例中,第一用户设备首先接收第一数据包,第一用户设备可以确定第一数据包中是否携带第一用户设备的身份相关信息,若有,则第一用户设备再接收第二数据包,并对第二数据包进行处理,如果第二数据包中携带第一用户设备对应的第一下行信息,则第一用户设备就可以从第二数据包中获取第一下行信息,否则如果第一数据包中没有携带第一用户设备的身份相关信息,第一用户设备就无需接收第二数据包,因为一般来说,第一数据包中携带第一用户设备的身份相关信息,则第二数据包中才可能会携带与该用户设备对应的下行信息,如果第一数据包中没有携带第一用户设备的身份相关信息,那第二数据包中也就不会携带第一用户设备的下行信息,从而第一用户设备也就无需再接收第二数据包,例如下行信息为DCI,这样,用户设备无需接收每个DCI,减少了用户设备的工作量,节省了用户设备的处理时间,也缩短了用户设备接收DCI的时间,提高了用户设备接收DCI的效率,降低了用户设备的功耗。
