实施例1
本发明实施例提供一种控制信息的传输方法,该方法应用于网络设备侧。
图2是本发明实施例1的控制信息的传输方法的一示意图。如图2所示,该方法包括:
步骤201:向用户设备指示第一控制信息是否重复发送以及重复发送的方式。
这样,通过向用户设备指示控制信息是否重复发送以及重复发送的方式,从而根据该指示的内容获取控制信息,能够有效的提高控制信息传输的可靠性。
在本实施例中,第一控制信息是网络设备向用户设备发送的用于进行下行控制的信息,例如,下行控制信息(Downlink Control Information,DCI)。
例如,下行控制信息通过物理下行控制信道(PDCCH)进行传输。
在本实施例中,该方法适用于单链路系统或多链路系统,由单链路系统中的网络设备或者多链路系统中的至少一个网络设备执行。
例如,对于单链路系统来说,一个网络设备可以重复或不重复的向用户设备发送第一控制信息。
例如,对于多链路系统来说,至少两个网络设备中的各个网络设备可以都向用户设备发送相同的第一控制信息,对于各个网络设备,都可以重复或不重复的向用户设备发送第一控制信息。在向用户设备指示第一控制信息是否重复发送以及重复发送的方式时,可以由至少两个网络设备中的主网络设备进行指示。
在本实施例中,当多个网络设备都重复发送第一控制信息时,各个网络设备重复发送第一控制信息的方式可以相同,也可以不同,该相同的重复发送的方式或者各个网络设备各自的重复发送的方式可以由主网络设备进行指示。
在本实施例中,在各个网络设备各自不重复发送第一控制信息的情况下,具体的 指示方式如下。
在各个网络设备各自不重复的向用户设备发送第一控制信息的情况下,各个网络设备可以在相同或不同的时频资源上,或者在相同的频率且不同的时间上,或者在相同的时间且不同的频率上向用户设备发送该第一控制信息。
例如,各个网络设备各自不重复的向用户设备发送第一控制信息,在各个网络设备分别在相同的时频资源上发送第一控制信息的情况下,主网络设备指示的是不重复发送。
例如,各个网络设备各自不重复的向用户设备发送第一控制信息,在各个网络设备在不同的时频资源上发送第一控制信息的情况下,主网络设备指示重复发送且指示的重复发送的方式是在不同的时频资源上重复发送。
例如,各个网络设备各自不重复的向用户设备发送第一控制信息,在各个网络设备在相同的频率且不同的时间上发送第一控制信息的情况下,主网络设备指示重复发送且指示的重复发送的方式是在相同的频率且不同的时间上重复发送。
例如,各个网络设备各自不重复的向用户设备发送第一控制信息,在各个网络设备在相同的时间且不同的频率上发送第一控制信息的情况下,主网络设备指示重复发送且指示的重复发送的方式是在相同的时间且不同的频率上重复发送。例如,对于多链路系统来说,也可以由至少两个网络设备中的一个网络设备作为主网络设备向用户设备发送该第一控制信息,其中,对于该主网络设备,也可以重复或不重复的向用户设备发送第一控制信息。
以下对第一控制信息重复发送的情况进行示例性的说明。
在本实施例中,第一控制信息可以在不同的时频资源上重复发送,也就是说,第一控制信息在不同的时间以及不同的频率上进行重复发送。
例如,在单链路的场景下,一个网络设备在不同的时间以及不同的频率上重复发送该第一控制信息。
例如,在具有理想回传链路的CoMP场景下,不同的网络设备可以使用不同的控制资源集合(control resource set,CORESET)发送该第一控制信息。
又例如,在载波聚合(carrier aggregation,CA)场景下,不同小区(carrier)使用不同的CORESET发送该第一控制信息。
在本实施例中,第一控制信息也可以在相同的频率且不同的时间上重复发送。
例如,在单链路的场景下,一个网络设备在相同的频率且不同的时间上重复发送该第一控制信息。
例如,在具有理想回传链路的CoMP场景下,不同的网络设备可以在相同的频率上使用不同的符号或微时隙(mini-slot)发送该第一控制信息。
又例如,在载波聚合场景下,不同小区在相同的频率上使用不同的符号或微时隙(mini-slot)发送该第一控制信息。
在本实施例中,第一控制信息还可以在相同的时间且不同的频率上重复发送。
例如,在单链路的场景下,一个网络设备在相同的时间且不同的频率上重复发送该第一控制信息。
例如,在具有理想回传链路的CoMP场景下,不同的网络设备可以在相同的时间且同一频段内以固定的频率间隔发送该第一控制信息。
又例如,在载波聚合场景下,不同小区在相同的时间且不同的频段上发送该第一控制信息。
在本实施例中,可以通过显式指示的方式来指示第一控制信息是否重复发送以及重复发送的方式。例如,可以通过高层信令中的第一重复指示参数指示第一控制信息是否重复发送以及重复发送的方式。例如,该高层信令可以是RRC信令或MAC-CE信令,该第一重复指示参数可以是PDCCHRepetitionIndication参数。
例如,PDCCHRepetitionIndication参数可以由2个字节构成。例如,当PDCCHRepetitionIndication为00时,表示第一控制信息不重复发送;当PDCCHRepetitionIndication为01时,表示第一控制信息在不同的时频资源上重复发送;当PDCCHRepetitionIndication为10时,表示第一控制信息在相同的频率且不同的时间上重复发送;当PDCCHRepetitionIndication为11时,表示第一控制信息在相同的时间且不同的频率上重复发送。
在本实施例中,可以通过隐式指示的方式来指示第一控制信息是否重复发送以及重复发送的方式。例如,也可以通过与第一控制信息的解调参考信号(Demodulation Reference Signal,DMRS)相乘的第一正交序列指示第一控制信息是否重复发送以及重复发送的方式。例如,该第一正交序列可以是正交覆盖码(Orthogonal Cover Code,OCC)。
例如,当DMRS与OCC码[1 1 1 1]相乘时,表示第一控制信息不重复发送;当 DMRS与OCC码[1 -1 1 -1]相乘时,表示第一控制信息在不同的时频资源上重复发送;当DMRS与OCC码[1 1 -1 -1]相乘时,表示第一控制信息在相同的频率且不同的时间上重复发送;当DMRS与OCC码[1 -1 -1 1]相乘时,表示第一控制信息在相同的时间且不同的频率上重复发送。
在本实施例中,还可以通过显式指示和隐式指示相结合的方式来指示第一控制信息是否重复发送以及重复发送的方式。例如,还可以通过高层信令中的第一重复指示参数以及与第一控制信息的解调参考信号(DMRS)相乘的第二正交序列指示第一控制信息是否重复发送以及重复发送的方式。例如,该高层信令可以是RRC信令或MAC-CE信令,该第一重复指示参数可以是PDCCHRepetitionIndication参数,该第二正交序列可以是ZC(Zadoff-Chu)序列。
例如,PDCCHRepetitionIndication参数可以由1个字节构成。例如,当PDCCHRepetitionIndication为0时,表示第一控制信息不重复发送;当PDCCHRepetitionIndication为1时,表示第一控制信息重复发送。
在第一控制信息重复发送的情况下,当DMRS与ZC序列
相乘时,表示第一控制信息在不同的时频资源上重复发送;当DMRS与ZC序列
相乘时,表示第一控制信息在相同的频率且不同的时间上重复发送;当DMRS与ZC序列
相乘时,表示第一控制信息在相同的时间且不同的频率上重复发送。
在本实施例中,该方法还可以包括:
步骤202:在第一控制信息重复发送的情况下,按照向该用户设备指示的重复发送的方式,向该用户设备重复发送该第一控制信息;
步骤203:在第一控制信息不重复发送的情况下,向该用户设备发送该第一控制信息。
图3是本发明实施例1的控制信息的传输方法的另一示意图。该方法用于多链路系统,该多链路系统包括第一网络设备以及至少一个其他网络设备。如图3所示,该方法包括:
步骤301:第一网络设备向用户设备指示第一控制信息是否重复发送以及重复发送的方式;
步骤302:在第一控制信息重复发送的情况下,第一网络设备和至少一个其他网络设备按照向该用户设备指示的重复发送的方式,向该用户设备重复发送该第一控制信息;
步骤303:在第一控制信息不重复发送的情况下,第一网络设备和至少一个其他网络设备向该用户设备发送该第一控制信息。
图4是本发明实施例1的控制信息的传输方法的又一示意图。该方法用于多链路系统,该多链路系统包括第一网络设备以及至少一个其他网络设备。如图4所示,该方法包括:
步骤401:第一网络设备向用户设备指示第一控制信息是否重复发送以及重复发送的方式;
步骤402:在第一控制信息重复发送的情况下,仅由第一网络设备按照向该用户设备指示的重复发送的方式,向该用户设备重复发送该第一控制信息;
步骤403:在第一控制信息不重复发送的情况下,仅由第一网络设备向该用户设备发送该第一控制信息。
在本实施例中,该第一网络设备例如是主网络设备,其可以是预先指定的或者按照预设条件确定的,本发明实施例不对主网络设备的确定方式进行限制。
例如,该第一网络设备是在多链路系统的所有网络设备中能够使得预编码后信道的信噪比最大的网络设备。
在本实施例中,该第一网络设备例如是所有网络设备中的任一个网络设备指定的,也可以是单独设置的网络设备控制器指定的。
在本实施例中,网络设备还可以向用户设备发送数据信息,用户设备根据获得的控制信息对接收到的数据信息进行解调。
由上述实施例可知,通过向用户设备指示控制信息是否重复发送以及重复发送的方式,从而根据该指示的内容获取控制信息,能够有效的提高控制信息传输的可靠性。
实施例2
本发明实施例提供一种控制信息的传输方法,该方法应用于用户设备侧,该方法对应于实施例1的应用于网络设备侧的控制信息的传输方法。
图5是本发明实施例2的控制信息的传输方法的一示意图。如图5所示,该方法包括:
步骤501:根据接收信号确定第一控制信息是否重复发送以及重复发送的方式。
以下对本实施例的根据接收信号确定第一控制信息是否重复发送以及重复发送的方式的方法进行示例性的说明。
图6是图5的步骤501的确定方法的一示意图。如图6所示,该方法包括:
步骤601:根据高层信令中的第一重复指示参数,确定所述第一控制信息是否重复发送以及重复发送的方式。
在本实施例中,该高层信令可以是RRC信令或MAC-CE信令,该第一重复指示参数可以是PDCCHRepetitionIndication参数。该PDCCHRepetitionIndication参数由2个字节构成。
例如,当PDCCHRepetitionIndication为00时,确定第一控制信息不重复发送;当PDCCHRepetitionIndication为01时,确定第一控制信息在不同的时频资源上重复发送;当PDCCHRepetitionIndication为10时,确定第一控制信息在相同的频率且不同的时间上重复发送;当PDCCHRepetitionIndication为11时,确定第一控制信息在相同的时间且不同的频率上重复发送。
图7是图5的步骤501的确定方法的另一示意图。如图7所示,该方法包括:
步骤701:计算接收到的解调参考信号和与第一正交序列相乘的解调参考信号之间的相关性;
步骤702:根据计算出的相关性确定该第一正交序列;以及
步骤703:根据该第一正交序列确定该第一控制信息是否重复发送以及重复发送的方式。
在本实施例中,该第一正交序列可以是正交覆盖码(Orthogonal Cover Code,OCC)。
例如,计算接收到的DMRS与乘以不同OCC码的DMRS之间的相关系数,其中,计算出的相关系数最大的OCC码即为所使用的OCC码,当确定的OCC为[1 1 1 1]时,确定第一控制信息不重复发送;当确定使用的OCC码为[1 -1 1 -1]时,确定第一控制信息在不同的时频资源上重复发送;当确定使用的OCC码为[1 1 -1 -1]时,确定第一控制信息在相同的频率且不同的时间上重复发送;当确定使用的OCC码为[1 -1 -1 1]时,确定第一控制信息在相同的时间且不同的频率上重复发送。
图8是图5的步骤501的确定方法的又一示意图。如图8所示,该方法包括:
步骤801:根据接收到的高层信令中第一重复指示参数,确定第一控制信息是否 重复发送;
步骤802:在判断第一控制信息重复发送的情况下,计算接收到的解调参考信号和与第二正交序列相乘的解调参考信号之间的相关性;
步骤803:根据计算出的相关性确定第二正交序列;以及
步骤804:根据第二正交序列,确定第一控制信息重复发送的方式。
在本实施例中,该高层信令可以是RRC信令或MAC-CE信令,该第一重复指示参数可以是PDCCHRepetitionIndication参数。该PDCCHRepetitionIndication参数由1个字节构成。
例如,当PDCCHRepetitionIndication为0时,确定第一控制信息不重复发送;当PDCCHRepetitionIndication为1时,确定第一控制信息重复发送。
在判断第一控制信息重复发送的情况下,计算接收到的DMRS与乘以不同ZC序列的DMRS之间的相关系数,其中,计算出的相关系数最大的ZC序列即为所使用的ZC序列,当确定使用的ZC序列为
时,确定第一控制信息在不同的时频资源上重复发送;当确定使用的ZC序列为
时,确定第一控制信息在相同的频率且不同的时间上重复发送;当确定使用的ZC序列为
时,确定第一控制信息在相同的时间且不同的频率上重复发送。
在本实施例中,如图5所示,该方法还可以包括:
步骤502:在根据接收信号确定第一控制信息重复发送的情况下,根据预定义的规则确定重复发送所述第一控制信息可能使用的物理资源;
步骤503:将在可能使用的物理资源上接收的多个接收信号进行合并;
步骤504:在合并后的接收信号中对该第一控制信息进行盲检。
这样,通过在合并后的接收信号中盲检控制信息,能够进一步提高控制信息传输的可靠性。
在本实施例中,该预定义的规则可以和具体的应用场景有关。
对于第一控制信息在不同的时频资源上重复发送的情况,例如,在CoMP场景下,不同的网络设备分别使用不同的CORESET重复发送第一控制信息;在CA场景下,不同小区分别使用不同的CORESET重复发送第一控制信息。该预定义的规则例如是,不同的网络设备或小区在不同CORESET上的相对起始位置相同处发送第一控 制信息。
对于第一控制信息在不同的时频资源上重复发送的情况,例如,在CoMP场景下,不同的网络设备分别使用不同的符号或微时隙(mini-slot)发送该第一控制信息;在CA场景下,不同小区在相同的频率上使用不同的符号或微时隙(mini-slot)发送该第一控制信息。该预定义的规则例如是,不同的网络设备或小区在相邻的符号或微时隙上发送该第一控制信息。
对于第一控制信息在相同的时间且不同的频率上重复发送的情况,例如,在CoMP场景下,不同的网络设备可以在相同的时间且同一频段内以固定的频率间隔发送该第一控制信息;在CA场景下,不同小区在相同的时间且不同的频段上发送该第一控制信息。该预定义的规则例如是,不同的网络设备或小区以预定义的频率间隔发送该第一控制信息。
在步骤502中,根据预定义的规则确定了重复发送该第一控制信息可能使用的物理资源。
在步骤503和504中,将在可能使用的物理资源上接收的多个接收信号进行合并,在合并后的接收信号中对该第一控制信息进行盲检,从而获得该第一控制信息。具体的盲检方法可以参考现有技术,此处不再赘述。
以上使用的是将接收信号合并后再盲检的方法,另外,也可以不进行合并,依次在各个物理资源上进行盲检,直到盲检成功为止。
图9是本发明实施例2的控制信息的传输方法的另一示意图。如图9所示,该方法包括:
步骤901:根据接收信号确定第一控制信息是否重复发送以及重复发送的方式;
步骤902:在根据接收信号确定第一控制信息重复发送的情况下,在不同的物理资源上依次对该第一控制信息进行盲检,直到成功解调出该第一控制信息为止。
例如,当不同的网络设备或小区在不同的符号或微时隙上发送该第一控制信息时,用户设备在第一个监测机会(monitoring occasion)上对第一控制信息进行盲检,如果盲检成功,则停止盲检;否则将在第二个监测机会上进行盲检,以此类推,直到成功解调出该第一控制信息为止。
在本实施例中,用户设备还可以根据获得的控制信息对接收到的数据信息进行解调,获得数据信息。
由上述实施例可知,通过根据接收信号确定第一控制信息是否重复发送以及重复发送的方式,从而根据确定的结果获取控制信息,能够有效的提高控制信息传输的可靠性。

在步骤1601中,第一网络设备1301可以通过实施例1中记载的各种方式进行指示。
例如,通过RRC信令或MAC-CE信令中的PDCCHRepetitionIndication参数指示第一控制信息重复发送,即,将PDCCHRepetitionIndication参数置为01、10或11,
例如,通过与第一控制信息的DMRS相乘的OCC码来指示,例如,将第一控制信息的DMRS与OCC码[1 -1 1 -1]、[1 1 -1 -1]或[1 -1 -1 1]相乘。
又例如,通过RRC信令或MAC-CE信令中的PDCCHRepetitionIndication参数以及与第一控制信息的DMRS相乘的ZC序列来指示,例如,将PDCCHRepetitionIndication参数置为1,并将第一控制信息的DMRS与ZC序列

相乘。
在步骤1601中,作为主网络设备的第一网络设备1301向用户指示多链路系统中的各个网络设备是否重复发送第一控制信息以及重复发送第一控制信息的方式,其中,各个网络设备重复发送第一控制信息的方式可以相同,也可以不同。

例如,首先通过接收到的RRC信令或MAC-CE信令中的PDCCHRepetitionIndication参数确定第一控制信息重复发送,即,该PDCCHRepetitionIndication参数为1;然后,计算接收到的DMRS和与ZC序列相乘的DMRS之间的相关系数,当计算出的相关系数最大的ZC序列为

时,确定第一控制信息在相同的频率且不同的时间上重复发送;当计算出的相关系数最大的ZC序列为
时,确定第一控制信息在相同的时间且不同的频率上重复发送。
在步骤1604中,用户设备1304可以通过实施例2中记载的各种预定的规则确定 重复发送第一控制信息可能使用的物理资源。
