相关申请的交叉引用
本申请主张在2020年4月22日在中国提交的中国专利申请号No.202010323610.0的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种控制信令格式确定方法、指示方法及设备。
背景技术
第五代移动通信技术(5th-Generation，5G)新空口(New Radio，NR)系统中，控制信令的格式随着使用的需求，设计了更为灵活多样的格式，如：第一版本支持下行控制信令(Downlink Control Information，DCI)的四种格式0_0、0_1、1_0和1_1，分别用于上下行调度；之后，为了支持更灵活的DCI大小，引入了新的DCI格式0_2与1_2，而未来可能会有更多的格式。
但是，在实现本申请过程中，发明人发现现有技术中至少存在如下问题：控制信令的格式数量超过用户侧设备(User Equipment，UE)支持的不同大小的控制信令数的限制，提高了UE的硬件成本与盲检复杂度。而当不同格式的控制信令大小相同时，UE无法区分不同的控制信令，从而导致通信失败。
发明内容
本申请实施例的目的是提供一种控制信令格式确定方法、指示方法及设备，能够解决因控制信令的格式数量超过系统规定的UE的控制信令大小的限制，提高了UE的硬件成本与盲检复杂度的问题。
为了解决上述技术问题，本申请是这样实现的：

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的一种控制信令格式确定方法进行详细地说明。
本申请实施例的控制信令格式确定方法应用于用户侧设备UE，具体的可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备。
如图1所示，本申请实施例的一种控制信令格式确定方法，包括：
步骤101，获取控制信令的指示信息，其中所述指示信息用于指示所述控制信令的格式。
按照该步骤，用户侧设备能够通过获取控制信令的指示信息，由该指示信息直接了解到该控制信令的格式，如此，在灵活支持多种控制信令格式的 同时，还可保持用户侧设备盲检控制信令的大小限制，降低了用户侧设备的实现复杂度，节省了用户设备的功耗与成本。
其中，控制信令可以是DCI，也可以是无线资源控制信令(Radio Resource Control，RRC)，又或者媒体接入控制控制单元信令(Media Access Control Control Element，MAC CE)等等。以下实施例中将以DCI为例进行具体说明。
应用本申请实施例的控制信令格式确定方法的UE，通过获取DCI的指示信息，由该指示信息能够获知该DCI的具体格式，如DCI 1-1，而不仅限于知道该DCI用于上行调度或下行调度。而且，该指示信息能够实现区分不同公共DCI，还可以实现区分公共DCI和针对UE的特定DCI。
该实施例中，可选地，所述指示信息为所述控制信令的第一信息域中的信息，其中所述第一信息域专用于指示所述控制信令的格式。
如此，对于用于指示控制信令的格式的指示信息，在控制信令中会引入专用的域，即第一信息域。当然，该第一信息域在UE监听该控制信令的所有部分带宽BWP、所有搜索空间及所有监听机会将一直存在。
例如，DCI中引入第一信息域T，用于指示DCI的具体格式。具体的，域T可指示用于下行调度的DCI中的一种，即UE通过域T获知该DCI是DCI 1_0、DCI 1_2或DCI 1_x。
可选地，所述第一信息域位于所述控制信令中的预设位置处，所述预设位置为：
起始位置；或者，
结束位置；或者，
目标域之前或之后的位置。
如此，第一信息域可位于控制信令中的起始位置，即第一信息域为该控制信令的第一个域；或者，第一信息域可位于控制信令中的结束位置，即第一信息域为该控制信令的最后一个域，但该域是位于循环冗余校验(Cyclic redundancy check，CRC)之前；或者，第一信息域可位于控制信令中目标域之前或之后的位置。例如，对于DCI，若目标域是1bit的、用于区分上下行格式的DCI格式标识(Identifier for DCI formats)域，T的位置可为Identifier for DCI formats域之后的位置；若目标域是载波标识(Carrier indicator)，上 行链路或补充的上行链路标识(UL/SUL indicator)，部分带宽标识(Bandwidth part indicator)，深度流检测标志(Deep Flow Inspection Flag，DFI flag)，或频域资源分配(Frequency domain resource assignment)等域，T的位置可为目标域之前的位置。
该实施例中，一方面，可选地，在步骤101之前，还包括：
接收网络侧设备发送的配置信息，所述配置信息用于指示所述控制信令中是否存在所述指示信息。
如此，UE能够根据接收到的配置信息，了解到控制信令中是否存在指示信息，从而进行指示信息的获取。当然，该配置信息还可以包括指示控制信令中指示信息具体位置的信息，指示信息的大小，指示信息的内容，或者，与存在指示信息的控制信令对应的格式等等。
其中，配置信息可通过网络侧设备发送的RRC、MAC CE或DCI(如组公共(group common)DCI)等携带。
另一方面，可选地，在满足预设条件的情况下，所述控制信令携带所述指示信息。
这里，控制信令将针对预设条件，在满足预设条件的情况下携带该指示信息。具体地，对于通过第一信息域携带该指示信息的实现方式，是否存在第一信息域，将根据是否满足预设条件确定。例如，DCI在满足预设条件的情况下，会引入T携带该指示信息。而控制信令不携带指示信息，除不引入第一信息域(如该第一信息域的大小为0比特)之外，还可以由第一信息域的值为预设值(如0)来表示。
该实施例中，可选地，所述预设条件包括以下至少一项：
控制信令对应预设部分带宽BWP；
控制信令对应预设搜索空间；
控制信令对应预设控制资源集；
控制信令对应预设监听时机；
控制信令为第一预设格式；
控制信令支持预设功能；
监听的控制信令中，具有不同第一大小的控制信令的数量大于预设值；
监听的多个控制信令中，存在至少两个控制信令的第一大小相同；
监听的多个控制信令中，存在至少两个控制信令的扰码相同；
监听的多个控制信令中，存在至少两个控制信令使用相同的无线网络临时标识RNTI加扰循环冗余校验CRC；
监听的多个控制信令中，存在至少两个控制信令的控制信道单元CCE重叠。
这样，在满足上述至少一项内容的情况下，控制信令将携带指示其格式的指示信息。其中，第一预设格式可以是一个特定格式，当然也可以是特定类别的一组或多个格式，例如对于DCI，其对应的第一预设格式可仅为DCI 1_0，也可为用于下行调度的DCI格式：DCI 1_0、DCI 1_1和DCI 1_2。第一大小是基于控制信令功能或载荷(payload)而确定的该控制信令的大小，该第一大小的控制信令不考虑是否包括指示控制信令的格式的指示信息。而预设值可以是系统预定义或网络配置或UE支持的不同大小的DCI的数量，如对应于DCI，该预设值可为UE的DCI大小预算size budget，DCI size budget是对于每个小区，UE最多监听的不同大小的DCI的数量。例如，监听的DCI格式A的第一大小与DCI格式B的第一大小相同，但监听时机或CCE不重叠，则不携带该指示信息。
当然，若网络侧设备配置控制信令存在第一信息域，且满足上述的预设条件，则第一信息域中包括该指示信息。如，网络侧设备配置DCI存在T，且满足上述的预设条件，该T中将会包括指示DCI格式的指示信息。
可选地，所述控制信令为满足所述预设条件的一个或多个控制信令。
如此，对于满足预设条件的情况，将有一个或多个控制信令携带该指示信息。而在满足该预设条件时，对于哪些控制信令可携带该指示信息，可由控制信令的格式确定。例如，预设条件是监听的多个DCI中，存在至少两个DCI的第一大小相同，则在满足该预设条件时，该至少两个DCI中，可全部携带该指示信息，也可以部分携带该指示信息，具体的，携带该指示信息的部分DCI可以是非基本调度non-fallback DCI。应该知道的是，基本调度fallback DCI包括DCI 1_0与0_0，可以在公共搜索空间(Common search space，CSS)里面监听。而non-fallback DCI则是指fallback DCI以外的其他UE特 定DCI格式。
此外，该实施例中，可选地，所述控制信令为第二预设格式的控制信令。
这样，UE将仅能够获取第二预设格式的控制信令的该指示信息。其中，该第二预设格式可以是一个特定格式，当然也可以是特定类别的一组或多个格式。例如对于DCI，其对应的第二预设格式可仅为DCI 0_1，也可为non-fallback上行调度格式，即DCI 0_1和DCI 0_2。
当然，若指示信息为控制信令的第一信息域中的信息，对应于第二预设格式，第一信息域将与第二预设格式关联，即非第二预设格式的控制信令中不包含第一信息域。例如，对于DCI，第二预设格式为DCI 0_1，则T关联于DCI 0_1，即DCI 0_2中不包含T，从而UE可以根据DCI大小区分不同DCI格式。
该实施例中，可选地，所述指示信息的大小是网络侧设备配置的；或者，
与用户侧设备监听的控制信令的格式数量对应；或者，
与包括指示信息的控制信令的格式数量对应。
其中，网络侧设备可通过配置信息配置该指示信息的大小，如0、1或2bit。若该指示信息的大小与用户侧设备监听的控制信令的格式数量对应，则该指示信息的大小可以等于用户侧设备监听的控制信令的格式数量，也可基于用户侧设备监听的控制信令的格式数量由预设相关函数进行计算确定，例如，指示信息的大小为S比特，
Figure PCTCN2021087717-appb-000001
N为监听的控制信令的格式数量。同样的，若该指示信息的大小与包括指示信息的控制信令的格式数量对应，则该指示信息的大小可以等于包括指示信息的控制信令的格式数量，也可基于包括指示信息的控制信令的格式数量由预设相关函数进行计算确定例如，指示信息的大小为S比特，
Figure PCTCN2021087717-appb-000002
M为包括指示信息的控制信令的格式数量。
以DCI为例，若第二预设格式为上行调度格式，即DCI 0_0和DCI 0_1，则包括指示信息的DCI的格式数量为2，则该指示信息的大小为1比特。
当然，若指示信息为控制信令的第一信息域中的信息，则该指示信息的大小即第一信息域的大小。
该实施例中，可选地，所述指示信息的内容是预定义的，或者，网络侧 设备配置的。
其中，对于预定义的指示信息的内容，UE获取到该指示信息，能够直接了解到该指示信息指示的控制信令的格式；对于网络侧设备配置的指示信息的内容，UE需通过网络侧设备的配置信息，先了解对该指示信息的内容的配置，从而在获取到指示信息后，才可获知该指示信息指示的控制信令的格式。
另外，该实施例中，可选地，所述指示信息中，每个码点与控制信令的格式对应；或者，
所述指示信息的值与控制信令的格式对应。
这样，通过预定义或者网络侧设备配置，一种实现是该指示信息中每个码点与控制信令的格式对应；一种实现是该指示信息的值与控制信令的格式对应。
例如，对于DCI，假设共有4种DCI格式A、B、C、D，则指示信息的大小可为4bit，每个比特位对应一种DCI格式，当DCI的指示信息为“1000”，即可指示该DCI为格式A；当DCI的指示信息为“0100”，即可指示该DCI为格式B；当DCI的指示信息为“0010”，即可指示该DCI为格式C；当DCI的指示信息为“0001”即可指示该DCI为格式D。又或者，指示信息的大小可为2bit，2bit信息的值对应一种DCI格式，当DCI的指示信息为“00”，即可指示该DCI为格式A；当DCI的指示信息为“01”，即可指示该DCI为格式B；当DCI的指示信息为“10”，即可指示该DCI为格式C；当DCI的指示信息为“11”即可指示该DCI为格式D。上述DCI格式A、B、C、D也可以是一对或一组特定DCI格式。
该实施例中，可选地，所述控制信令的第二大小与包括指示信息的其它控制信令的第二大小相同。
这样，对于包括指示信息的多个控制信令的第二大小相同。若控制信令引入第一信息域，则对于引入第一信息域的多个控制信令，包括第一信息域的控制信令的第二大小相同。如果包括第一信息域的控制信令的第二大小不同，可以将这些控制信令填充并对其到相同的大小。
可选地，所述指示信息与预设域的信息联合编码。
以预设域为Identifier for DCI formats域为例，每个码点同时指示了DCI 格式是上行还是下行调度，是DCI x_1，还是x_2,x_3……。当然，预设域也可以是除此之外的其他域，在此不再一一列举。
因此，结合本申请实施例的方法，以T关联DCI 1_1与DCI 1_3为例，DCI设计一，不同DCI格式定义不同的T的值：
DCI 1_1：1bit的Identifier for DCI formats域，比特位的值总是设置为1，表示下行DL DCI格式；T位于Identifier for DCI formats域之后，T的大小为0或1比特，由高层参数决定，如果T的值总是设置为0，表示DCI格式为1_1。此时，域T还可以用于DCI格式验证，例如，当UE盲检测到DCI 1_1，但对应域T的值却与预定义或配置的值不同(例如，T的值总是设置为1，但检测到的值为0)，则说明该盲检测是误检(false alarm)。当然，格式中还有其他域的设置，在此不再一一说明。
DCI 1_3：1bit的Identifier for DCI formats域，比特位的值总是设置为1，表示下行DL DCI格式；T位于Identifier for DCI formats域之后，T的大小为0或1比特，由高层参数决定，如果T的值总是设置为1，表示DCI格式为1_3。当然，格式中还有其他域的设置，在此不再一一说明。
DCI设计二，网络侧设备配置T的大小，以及不同DCI格式对应的T的值：
DCI 1_1：1bit的Identifier for DCI formats域，比特位的值总是设置为1，表示下行DL DCI格式；T位于Identifier for DCI formats域之后，T的大小为0、1或2比特，由高层参数决定，T的值由高层参数配置。当然，格式中还有其他域的设置，在此不再一一说明。
DCI 1_3：1bit的Identifier for DCI formats域，比特位的值总是设置为1，表示下行DL DCI格式；T位于Identifier for DCI formats域之后，T的大小为0、1或2比特，由高层参数决定，T的值由高层参数配置。当然，格式中还有其他域的设置，在此不再一一说明。
场景一：网络侧设备配置了DCI 1_1与DCI 1_3在所有BWP上大小相等，从而可以共享UE的DCI budget，降低盲检复杂度。为区分DCI 1_1与DCI 1_3，网络侧设备在DCI中配置了域T，T的大小为1比特，从而UE可以根据域T区分DCI 1_1与DCI 1_3。
场景二、网络侧设备配置了DCI 1_1与DCI 1_3大小相等，从而可以共享UE的DCI budget，降低盲检复杂度。网络侧设备分别为DCI 1_1与DCI 1_3配置不同的搜索空间或不同的CORESET。UE在搜索空间或CORESET中盲检测关联该搜索空间或CORESET的DCI格式，从而UE可以根据域T区分DCI 1_1与DCI 1_3。
场景三、网络侧设备配置了DCI 1_1与DCI 1_3大小相等，从而可以共享UE的DCI budget，降低盲检复杂度。网络侧设备通过RRC配置，在DCI中配置了域T用于区分DCI 1_1与DCI 1_3。网络侧设备通过MAC CE，指示某个小区，或某个BWP，或某个CORESET，或某个搜索空间中DCI中是否实际存在域T(即，MAC CE激活该域T为0bit或1bit)。UE根据MAC CE指示，按照不同的DCI大小盲检测物理下行控制信道PDCCH，若MAC CE指示域T存在，则根据域T区分DCI 1_1与DCI 1_3；若MAC CE指示域T不存在，则按照预定义的格式(可以是DCI 1_1或1_3)盲检测PDCCH。在该场景中，网络侧设备可以根据实际需要动态开启域T。
场景四、网络侧设备配置了DCI 1_1与DCI 1_3且大小不同，并配置了域T用于区分DCI 1_1与DCI 1_3。如果UE当前监听的不同大小的DCI数量小于DCI budget(例如，4个)，则按照每个DCI大小进行盲检，且DCI中域T不存在；如果UE当前监听的不同大小的DCI数量超过DCI budget，则把DCI 1_1与DCI 1_3的大小对齐，且DCI中域T存在，用于区分DCI格式。
此外，该实施例中，控制信令除使用专用的指示控制信令的格式域外，可选地，所述指示信息为所述控制信令的第二信息域中的信息，其中所述第二信息域复用于指示所述控制信令的格式。
这里，第二信息域除指示控制信令的格式之外，还可用于携带一个或多个其他信息。而在第二信息域中，可由部分或全部比特(或码点)用于指示控制信令的格式。具体的，网络侧设备配置第二信息域中哪些比特(或码点)用于指示控制信令的格式，以及每个比特(或码点)对应的控制信令的格式。
场景五、网络侧设备配置了cell 1跨载波调度cell 2(从而DCI 1_1中存在Carrier indicator)，且cell 1配置了DCI 1_3可以联合调度cell 1与cell 3。 DCI 1_1与DCI 1_3大小相等，从而可以共享UE的DCI budget，降低盲检复杂度。由于DCI 1_1中的Carrier indicator域(CIF)有3bits，跨载波调度了cell 2(此时，cell 1对应的CIF为0，cell 2对应的CIF为1)。因此，CIF的高两位固定为00。因此，可以把CIF的高一位或两位用于指示DCI 1_1与1_3，即如果CIF最高位是0，表示DCI格式1_1，否则表示DCI格式1_3。此时，DCI 1_3中的CIF域可以是2或3bits，且最高位是1。当然除了Carrier indicator，也可以使用Bandwidth part indicator，Identifier for DCI formats等域。
例如，当系统中DCI 1_1与DCI 0_1大小不同，但与DCI 1_3大小相同时，或者，该小区只配置了下行传输，因此UE不需要监听上行调度(即不需要监听DCI 0_1)，UE不需要通过Identifier for DCI formats域来区分上下行DCI格式(即DCI 1_1与DCI 0_1)，则可以复用Identifier for DCI formats域来区分两个下行DCI格式DCI 1_1与1_3。
综上所述，用户侧设备能够通过获取控制信令的指示信息，由该指示信息直接了解到该控制信令的格式，如此，在灵活支持多种控制信令格式的同时，还可保持用户侧设备盲检控制信令的大小限制，降低了用户侧设备的实现复杂度，节省了用户设备的功耗与成本。
如图2所示，本申请实施例提供了一种控制信令格式指示方法，包括：
步骤201，发送控制信令，其中所述控制信令包括指示信息，所述指示信息用于指示所述控制信令的格式。
按照该步骤，发送控制信令，以便用户侧设备能够通过获取控制信令的指示信息，由该指示信息直接了解到该控制信令的格式，如此，在灵活支持多种控制信令格式的同时，还可保持用户侧设备盲检控制信令的大小限制，降低了用户侧设备的实现复杂度，节省了用户设备的功耗与成本。
其中，控制信令可以是DCI，也可以是RRC(Radio Resource Control，无线资源控制信令)，又或者MAC CE(Media Access Control Control Element，媒体接入控制控制单元信令)等等。以下实施例中将以DCI为例进行具体说明。
例如，UE通过获取DCI的指示信息，由该指示信息能够获知该DCI的具体格式，如DCI 1-1，而不仅限于知道该DCI用于上行调度或下行调度。 而且，该指示信息能够实现区分不同公共DCI，还可以实现区分公共DCI和针对UE的特定DCI。
该实施例中，可选地，所述指示信息为所述控制信令的第一信息域中的信息，其中所述第一信息域专用于指示所述控制信令的格式。
如此，对于用于指示控制信令的格式的指示信息，在控制信令中会引入专用的域，即第一信息域。当然，该第一信息域在UE监听该控制信令的所有部分带宽BWP、所有搜索空间及所有监听机会将一直存在。
例如，DCI中引入第一信息域T，用于指示DCI的具体格式。具体的，域T可指示用于下行调度的DCI中的一种，即UE通过域T获知该DCI是DCI 1_0、DCI 1_2或DCI 1_x。
可选地，所述第一信息域位于所述控制信令中的预设位置处，所述预设位置为：
起始位置；或者，
结束位置；或者，
目标域之前或之后的位置。
如此，第一信息域可位于控制信令中的起始位置，即第一信息域为该控制信令的第一个域；或者，第一信息域可位于控制信令中的结束位置，即第一信息域为该控制信令的最后一个域，但该域是位于CRC之前；或者，第一信息域可位于控制信令中目标域之前或之后的位置。例如，对于DCI，若目标域是1bit的、用于区分上下行格式的DCI格式标识Identifier for DCI formats域，T的位置可为Identifier for DCI formats域之后的位置；若目标域是载波标识Carrier indicator，上行链路或补充的上行链路标识UL/SUL indicator，部分带宽标识Bandwidth part indicator，深度流检测标志DFI flag，或频域资源分配Frequency domain resource assignment等域，T的位置可为目标域之前的位置。
该实施例中，一方面，可选地，在步骤201之前，还包括：
发送配置信息，所述配置信息用于指示所述控制信令中是否存在所述指示信息。
如此，UE能够根据接收到的配置信息，了解到控制信令中是否存在指示 信息，从而进行指示信息的获取。当然，该配置信息还可以包括指示控制信令中指示信息具体位置的信息，指示信息的大小，指示信息的内容，或者，与存在指示信息的控制信令对应的格式等等。
其中，配置信息可通过网络侧设备发送的RRC、MAC CE或DCI(如组公共(group common)DCI)等携带。
另一方面，可选地，在满足预设条件的情况下，所述控制信令携带所述指示信息。
这里，控制信令将针对预设条件，在满足预设条件的情况下携带该指示信息。具体地，对于通过第一信息域携带该指示信息的实现方式，是否存在第一信息域，将根据是否满足预设条件确定。例如，DCI在满足预设条件的情况下，会引入T携带该指示信息。而控制信令不携带指示信息，除不引入第一信息域(如该第一信息域的大小为0比特)之外，还可以由第一信息域的值为预设值(如0)来表示。
该实施例中，可选地，所述预设条件包括以下至少一项：
控制信令对应预设部分带宽BWP；
控制信令对应预设搜索空间；
控制信令对应预设控制资源集；
控制信令对应预设监听时机；
控制信令为第一预设格式；
控制信令支持预设功能；
监听的控制信令中，具有不同第一大小的控制信令的数量大于预设值；
监听的多个控制信令中，存在至少两个控制信令的第一大小相同；
监听的多个控制信令中，存在至少两个控制信令的扰码相同；
监听的多个控制信令中，存在至少两个控制信令使用相同的无线网络临时标识RNTI加扰循环冗余校验CRC；
监听的多个控制信令中，存在至少两个控制信令的控制信道单元CCE重叠。
这样，在满足上述至少一项内容的情况下，控制信令将携带指示其格式的指示信息。其中，第一预设格式可以是一个特定格式，当然也可以是特定 类别的一组或多个格式，例如对于DCI，其对应的第一预设格式可仅为DCI 1_0，也可为用于下行调度的DCI格式：DCI 1_0、DCI 1_1和DCI 1_2。第一大小是基于控制信令功能或载荷(payload)而确定的该控制信令的大小，该第一大小的控制信令不考虑是否包括指示控制信令的格式的指示信息。而预设值可以是系统预定义或网络配置或UE支持的不同大小的DCI的数量，如对应于DCI，该预设值可为UE的DCI大小预算size budget，DCI size budget是对于每个小区，UE最多监听的不同大小的DCI的数量。
例如，监听的DCI格式A的第一大小与DCI格式B的第一大小相同，但监听时机或CCE不重叠，则不携带该指示信息。
当然，若网络侧设备配置控制信令存在第一信息域，且满足上述的预设条件，则第一信息域中包括该指示信息。如，网络侧设备配置DCI存在T，且满足上述的预设条件，该T中将会包括指示DCI格式的指示信息。
可选地，所述控制信令为满足所述预设条件的一个或多个控制信令。
如此，对于满足预设条件的情况，将有一个或多个控制信令携带该指示信息。而在满足该预设条件时，对于哪些控制信令可携带该指示信息，可由控制信令的格式确定。例如，预设条件是监听的多个DCI中，存在至少两个DCI的第一大小相同，则在满足该预设条件时，该至少两个DCI中，可全部携带该指示信息，也可以部分携带该指示信息，具体的，携带该指示信息的部分DCI可以是非基本调度non-fallback DCI。应该知道的是，基本调度fallback DCI包括DCI 1_0与0_0，可以在CSS里面监听。而non-fallback DCI则是指fallback DIC以外的其他UE特定DCI格式。
此外，该实施例中，可选地，所述控制信令为第二预设格式的控制信令。这样，UE将仅能够获取第二预设格式的控制信令的该指示信息。其中，该第二预设格式可以是一个特定格式，当然也可以是特定类别的一组或多个格式。例如对于DCI，其对应的第二预设格式可仅为DCI 0_1，也可为non-fallback上行调度格式，即DCI 0_1和DCI 0_2。
当然，若指示信息为控制信令的第一信息域中的信息，对应于第二预设格式，第一信息域将与第二预设格式关联，即非第二预设格式的控制信令中不包含第一信息域。例如，对于DCI，第二预设格式为DCI 0_1，则T关联 于DCI 0_1，即DCI 0_2中不包含T，从而UE可以根据DCI大小区分不同DCI格式。
该实施例中，可选地，所述指示信息的大小是网络侧设备配置的；或者，
与用户侧设备监听的控制信令的格式数量对应；或者，
与包括指示信息的控制信令的格式数量对应。
其中，网络侧设备可通过配置信息配置该指示信息的大小，如0、1或2bit。若该指示信息的大小与用户侧设备监听的控制信令的格式数量对应，则该指示信息的大小可以等于用户侧设备监听的控制信令的格式数量，也可基于用户侧设备监听的控制信令的格式数量由预设相关函数进行计算确定，例如，指示信息的大小为S比特，
Figure PCTCN2021087717-appb-000003
N为监听的控制信令的格式数量。同样的，若该指示信息的大小与包括指示信息的控制信令的格式数量对应，则该指示信息的大小可以等于包括指示信息的控制信令的格式数量，也可基于包括指示信息的控制信令的格式数量由预设相关函数进行计算确定，例如，指示信息的大小为S比特，
Figure PCTCN2021087717-appb-000004
M为包括指示信息的控制信令的格式数量。
以DCI为例，若第二预设格式为上行调度格式，即DCI 0_0和DCI 0_1，则包括指示信息的DCI的格式数量为2，则该指示信息的大小为1比特。
当然，若指示信息为控制信令的第一信息域中的信息，则该指示信息的大小即第一信息域的大小。
该实施例中，可选地，所述指示信息的内容是预定义的，或者，网络侧设备配置的。
其中，对于预定义的指示信息的内容，UE获取到该指示信息，能够直接了解到该指示信息指示的控制信令的格式；对于网络侧设备配置的指示信息的内容，UE需通过网络侧设备的配置信息，先了解对该指示信息的内容的配置，从而在获取到指示信息后，才可获知该指示信息指示的控制信令的格式。
另外，该实施例中，可选地，所述指示信息中，每个码点与控制信令的格式对应；或者，
所述指示信息的值与控制信令的格式对应。
这样，通过预定义或者网络侧设备配置，一种实现是该指示信息中每个 码点与控制信令的格式对应；一种实现是该指示信息的值与控制信令的格式对应。
例如，对于DCI，假设共有4种DCI格式A、B、C、D，则指示信息的大小可为4bit，每个比特位对应一种DCI格式，当DCI的指示信息为“1000”，即可指示该DCI为格式A；当DCI的指示信息为“0100”，即可指示该DCI为格式B；当DCI的指示信息为“0010”，即可指示该DCI为格式C；当DCI的指示信息为“0001”即可指示该DCI为格式D。又或者，指示信息的大小可为2bit，2bit信息的值对应一种DCI格式，当DCI的指示信息为“00”，即可指示该DCI为格式A；当DCI的指示信息为“01”，即可指示该DCI为格式B；当DCI的指示信息为“10”，即可指示该DCI为格式C；当DCI的指示信息为“11”即可指示该DCI为格式D。上述DCI格式A、B、C、D也可以是一对或一组特定DCI格式。
该实施例中，可选地，所述控制信令的第二大小与包括指示信息的其它控制信令的第二大小相同。
这样，对于包括指示信息的多个控制信令的第二大小相同。若控制信令引入第一信息域，则对于引入第一信息域的多个控制信令，包括第一信息域的控制信令的第二大小相同。如果包括第一信息域的控制信令的第二大小不同，可以将这些控制信令填充并对其到相同的大小。
可选地，所述指示信息与预设域的信息联合编码。
以预设域为Identifier for DCI formats域为例，每个码点同时指示了DCI格式是上行还是下行调度，是DCI x_1，还是x_2,x_3……。当然，预设域也可以是除此之外的其他域，在此不再一一列举。
此外，该实施例中，控制信令除使用专用的指示控制信令的格式域外，可选地，所述指示信息为所述控制信令的第二信息域中的信息，其中所述第二信息域复用于指示所述控制信令的格式。
这里，第二信息域除指示控制信令的格式之外，还可用于携带一个或多个其他信息。而在第二信息域中，可由部分或全部比特(或码点)用于指示控制信令的格式。具体的，网络侧设备配置第二信息域中哪些比特(或码点)用于指示控制信令的格式，以及每个比特(或码点)对应的控制信令的格式。
综上所述，网络侧设备发送控制信令，以便用户侧设备能够通过获取控制信令的指示信息，由该指示信息直接了解到该控制信令的格式，如此，在灵活支持多种控制信令格式的同时，还可保持用户侧设备盲检控制信令的大小限制，降低了用户侧设备的实现复杂度，节省了用户设备的功耗与成本。
