Description

一种多TRP***中PDCCH的监测方法A kind of monitoring method of PDCCH in multi-TRP system

【技术领域】【Technical field】

本发明的所公开实施例涉及通信技术领域，且更具体而言，涉及一种多TRP***中PDCCH的监测方法及用户设备。The disclosed embodiments of the present invention relate to the field of communication technologies, and more particularly, to a PDCCH monitoring method and user equipment in a multi-TRP system.

【背景技术】【Background technique】

用户设备(User Equipment,UE)需要知道物理下行控制信道(PDCCH:Physical Downlink Control Channel)在频域上的位置和时域上的位置才能成功解码PDCCH。在新空口(NR:New Radio)***中，将PDCCH的频域资源信息和时域占用的正交频分复用(OFDM:Orthogonal Frequency Division Multiplexing)符号数等信息封装在控制资源集合(CORESET:Control Resource Set)中，将PDCCH起始OFDM符号以及监听周期、关联的CORESET等信息封装在搜索空间(Search Space,SS)中。UE根据搜索空间和CORESET配置确定出PDCCH的候选时频位置后，这些候选的资源称为PDCCH候选。对每个候选PDCCH进行Polar解码和循环冗余校验(CRC:Cyclic Redundancy Check)，当CRC校验通过后，则表示当前候选PDCCH解调成功。User Equipment (UE) needs to know the location of the Physical Downlink Control Channel (PDCCH: Physical Downlink Control Channel) in the frequency domain and the location in the time domain to successfully decode the PDCCH. In the new air interface (NR: New Radio) system, the frequency domain resource information of the PDCCH and the number of orthogonal frequency division multiplexing (OFDM: Orthogonal Frequency Division Multiplexing) symbols occupied in the time domain are encapsulated in the control resource set (CORESET: Control Resource Set), the PDCCH starting OFDM symbol, monitoring period, associated CORESET and other information are encapsulated in a search space (Search Space, SS). After the UE determines the candidate time-frequency positions of the PDCCH according to the search space and the CORESET configuration, these candidate resources are called PDCCH candidates. Perform Polar decoding and Cyclic Redundancy Check (CRC: Cyclic Redundancy Check) on each candidate PDCCH. When the CRC check passes, it means that the current candidate PDCCH is successfully demodulated.

考虑到UE能力以及降低UE盲检复杂度，协议中对每个时隙(Slot)/跨度(Span)中监测(Monitor)的最大PDCCH候选个数与非重叠的(Non-Overlapped)控制信道单元(CCE:Control Channel Element)个数进行限制。因此如果PDCCH候选与非重叠的CCE数量超过了限制，在为UE配置的所有搜索空间集合中，只能选择一部分搜索空间集合进行监测。Taking into account the UE capability and reducing the complexity of UE blind detection, in the protocol, the maximum number of PDCCH candidates to monitor (Monitor) in each slot/span (Span) and the non-overlapped (Non-Overlapped) control channel elements (CCE: Control Channel Element) is limited. Therefore, if the number of PDCCH candidates and non-overlapping CCEs exceeds the limit, in all search space sets configured for the UE, only a part of the search space sets can be selected for monitoring.

由于从传输接收节点(TRP:Transmission/Reception Point)到UE之间PDCCH信道可能被阻塞，因此，需要增强PDCCH信道的可靠性。如图1所示，从多个TRP传输多个PDCCH(即：PDCCH1和PDCCH2)给一个UE，这些PDCCH使用不同的波束传输，并且指示相同的资源分配信息用于调度一个物理下行共享信道(PDSCH:Physical Downlink Share Channel)/物理上行共享信道(PUSCH:Physical Uplink Share Channel)等，PDCCH通过多TRP***传输能增强其可靠性。Since the PDCCH channel may be blocked from the transmission and reception node (TRP: Transmission/Reception Point) to the UE, it is necessary to enhance the reliability of the PDCCH channel. As shown in Figure 1, multiple PDCCHs (ie: PDCCH1 and PDCCH2) are transmitted from multiple TRPs to one UE, these PDCCHs are transmitted using different beams, and indicate the same resource allocation information for scheduling a physical downlink shared channel (PDSCH). : Physical Downlink Share Channel)/Physical Uplink Share Channel (PUSCH: Physical Uplink Share Channel), etc. PDCCH can enhance its reliability through multi-TRP system transmission.

在Non-SFN(Non-Single Frequency Network)下增强多TRP***中PDCCH传输，支持重复传输与两个PDCCH候选者显示地连接，并且具有连接关系的 PDCCH候选最大数目是2，但对于在此***中，PDCCH候选的盲解码次数的限制未做进一步定义，即在Non-SFN(Non-Single Frequency Network)下多TRP***中，若PDCCH候选与非重叠的CCE数量超过了限制，在为UE配置的所有搜索空间集合中，如何选择部分搜索空间集合进行监测。Enhanced PDCCH transmission in multi-TRP system under Non-SFN (Non-Single Frequency Network), supports repeated transmission to be explicitly connected with two PDCCH candidates, and the maximum number of PDCCH candidates with connection relationship is 2, but for this system , the limit on the number of blind decoding times for PDCCH candidates is not further defined, that is, in a multi-TRP system under Non-SFN (Non-Single Frequency Network), if the number of PDCCH candidates and non-overlapping CCEs exceeds the limit, the How to select part of the search space set for monitoring.

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，所描述的实施例仅是本申请一部分实施例，而不是全部实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性的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。The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

本申请提供一种多TRP***中PDCCH的监测方法。请参阅图2，图2是本申请实施例提供的监测方法的流程示意图。该监测方法包括：The present application provides a method for monitoring PDCCH in a multi-TRP system. Please refer to FIG. 2 , which is a schematic flowchart of a monitoring method provided by an embodiment of the present application. The monitoring method includes:

S100：根据搜索空间及对应的CORESET获取PDCCH候选。S100: Obtain PDCCH candidates according to the search space and the corresponding CORESET.

CORESET包括PDCCH的频域资源信息和时域占用的OFDM符号数等信息，搜索空间包括PDCCH起始OFDM符号以及监听周期、关联的CORESET等信息，CORESET包括PDCCH的频域资源信息和时域占用的OFDM符号数等信息。UE通过无线资源控制(Radio Resource Control,RRC)获取搜索空间信息和CORESET信息。进而通过搜索空间信息和CORESET的信息配置确定出PDCCH的候选时频位置，即为PDCCH候选，其PDCCH候选的个数可为多个。CORESET includes information such as frequency domain resource information of PDCCH and the number of OFDM symbols occupied in time domain. The search space includes PDCCH starting OFDM symbol, monitoring period, associated CORESET and other information. CORESET includes PDCCH frequency domain resource information and time domain occupied information. Information such as the number of OFDM symbols. The UE obtains search space information and CORESET information through Radio Resource Control (RRC). Further, the candidate time-frequency positions of the PDCCH are determined through the configuration of the search space information and the CORESET information, that is, the PDCCH candidates, and the number of the PDCCH candidates may be multiple.

S200：对PDCCH候选进行盲解码，以获取被成功解码的第一PDCCH候选，其中包括第一PDCCH候选的搜索空间为第一搜索空间集合，与第一PDCCH候选有显式连接关系的是第二PDCCH的候选。S200: Perform blind decoding on the PDCCH candidate to obtain a successfully decoded first PDCCH candidate, wherein the search space including the first PDCCH candidate is the first search space set, and the first PDCCH candidate has an explicit connection relationship with the second PDCCH candidate. Candidate for PDCCH.

对多个PDCCH候选进行盲解码包括对每个PDCCH候选进行Polar解码和循环冗余校验，循环冗余校验成功即为成功解码。解码成功的第一个PDCCH候选称为第一PDCCH候选。包括第一PDCCH候选的搜索空间称为第一搜索空间集合，该第一搜索空间集合中还可能包括其他的多个PDCCH候选。Performing blind decoding on multiple PDCCH candidates includes performing Polar decoding and cyclic redundancy check on each PDCCH candidate, and a successful cyclic redundancy check means successful decoding. The first PDCCH candidate that is successfully decoded is called the first PDCCH candidate. The search space including the first PDCCH candidate is called the first search space set, and the first search space set may also include other multiple PDCCH candidates.

从多TRP***传输的两个PDCCH候选的编码比特和DCI载荷都相同，第一PDCCH候选与第二PDCCH候选有显式连接关系。The coded bits and DCI payloads of the two PDCCH candidates transmitted from the multi-TRP system are the same, and the first PDCCH candidate and the second PDCCH candidate have an explicit connection relationship.

S300：根据搜索空间集合之间或CORESET之间的关系对其他搜索空间集合进行逐一监测，直到达到最大预设值；或根据第一PDCCH候选的相关信息对其他搜索空间集合进行逐一监测，直到达到最大预设值。S300: Monitor other search space sets one by one according to the relationship between search space sets or between CORESETs until the maximum preset value is reached; or monitor other search space sets one by one according to the relevant information of the first PDCCH candidate until the maximum value is reached default value.

具体地，比如可以通过第一搜索空间集合与另一个搜索空间集合之间的特定关系而得出的包括第二PDCCH的第二搜索空间集合，也可以是通过针对解码出的第一PDCCH候选的CORESET与另一个CORESET之间的特定关系而得出的包括第二PDCCH候选的第二搜索空间集合。当然也可以是根据第一PDCCH候选的相关信息而得出的第二PDCCH候选，然后基于该第二搜索空间集合或者该第二PDCCH候选，对剩余的搜索空间集合或PDCCH候选进行优先级排序监测，直到达到该UE监测的预设的最大值。从而使得UE可以根据第二PDCCH候选是否需要进行解码接收，可以在最大预设值的监测范围内，针对剩余的其他搜索空间集合或PDCCH候选的监测顺序进行优先级排序以实现资源利用最大化。Specifically, for example, the second search space set including the second PDCCH can be obtained through a specific relationship between the first search space set and another search space set, or it can be obtained from the decoded first PDCCH candidate. A second set of search spaces including second PDCCH candidates derived from a specific relationship between a CORESET and another CORESET. Of course, it can also be a second PDCCH candidate obtained according to the relevant information of the first PDCCH candidate, and then based on the second search space set or the second PDCCH candidate, the remaining search space sets or PDCCH candidates are prioritized and monitored. , until the preset maximum value monitored by the UE is reached. Therefore, according to whether the second PDCCH candidate needs to be decoded and received, the UE can prioritize the remaining other search space sets or the monitoring order of the PDCCH candidates within the monitoring range of the maximum preset value to maximize resource utilization.

在一实施例中，最大预设值为每个时隙或跨度中监测的PDCCH候选的最大个数与非重叠的控制信道单元CCE的最大个数。基于时隙或基于跨度的PDCCH候选的最大个数与非重叠的控制信道单元CCE的最大个数由高层参数进行配置。当UE被配置高层参数monitoringCapabilityConfig-r16，并且该参数的取值为另一个高层参数r15monitoringcapability，或者UE未被配置高层参数monitoringCapabilityConfig-r16，此种情况下UE使用基于时隙为单位的最大的PDCCH候选与非重叠的CCE数目进行监测。当UE被配置高层参数monitoringCapabilityConfig-r16，并且该参数的取值为另一个高层参数r16monitoringcapability，那么UE使用基于跨度(Span)为单位的最大的PDCCH候选与非重叠的CCE数目进行监测。以时隙为单位作为例子，如下表所示：In one embodiment, the maximum preset value is the maximum number of monitored PDCCH candidates and the maximum number of non-overlapping control channel elements CCEs in each time slot or span. The maximum number of slot-based or span-based PDCCH candidates and the maximum number of non-overlapping control channel elements CCEs are configured by higher layer parameters. When the UE is configured with the high-level parameter monitoringCapabilityConfig-r16, and the value of this parameter is another high-level parameter r15monitoringcapability, or the UE is not configured with the high-level parameter monitoringCapabilityConfig-r16, in this case, the UE uses the largest PDCCH candidate based on the time slot. Monitor with the number of non-overlapping CCEs. When the UE is configured with the high-level parameter monitoringCapabilityConfig-r16, and the value of this parameter is another high-level parameter r16monitoringcapability, the UE uses the largest PDCCH candidate and the number of non-overlapping CCEs based on the span (Span) for monitoring. Take the time slot as an example, as shown in the following table:

表1Table 1

表1是每个时隙监测的PDCCH候选的最大数目

表1中的最大数目在单个小区并且具有子载波间隔(SCS:Sub-Carrier Spacing)配置μ的一个下行部分带宽(BWP:Bandwidth Part)条件下。其中μ的取值为0、1、2和3时，分别表示子载波间隔为15kHz、30kHz、60kHz和120kHz。在一个确定的下行部分带宽内，子载波间隔越小，每个时隙能监测的PDCCH候选的数目越大。 Table 1 is the maximum number of PDCCH candidates monitored per slot

The maximum number in Table 1 is under the condition of a single cell and one downlink partial bandwidth (BWP: Bandwidth Part) with Sub-Carrier Spacing (SCS: Sub-Carrier Spacing) configuration μ. When the value of μ is 0, 1, 2 and 3, it means that the subcarrier spacing is 15kHz, 30kHz, 60kHz and 120kHz respectively. Within a certain downlink partial bandwidth, the smaller the subcarrier spacing is, the greater the number of PDCCH candidates that can be monitored in each time slot.

表2Table 2

表2是每个时隙的非重叠CCE的最大数目

表2中的最大数目在单个小区并且具有子载波间隔(SCS:Sub-Carrier Spacing)配置μ的一个下行部分带宽(BWP:Bandwidth Part)条件下。其中μ的取值为0、1、2和3时，分别表示子载波间隔为15kHz、30kHz、60kHz和120kHz。在一个确定的下行部分带宽内，子载波间隔越小，每个时隙能监测的非重叠的CCE的数目越大。 Table 2 is the maximum number of non-overlapping CCEs per slot

The maximum number in Table 2 is under the condition of a single cell and one downlink partial bandwidth (BWP: Bandwidth Part) with Sub-Carrier Spacing (SCS: Sub-Carrier Spacing) configuration μ. When the value of μ is 0, 1, 2 and 3, it means that the subcarrier spacing is 15kHz, 30kHz, 60kHz and 120kHz respectively. Within a certain downlink partial bandwidth, the smaller the subcarrier spacing is, the greater the number of non-overlapping CCEs that can be monitored in each time slot.

在一实施例中，根据搜索空间集合之间或CORESET之间的关系对其他搜索空间集合进行逐一监测，直到达到最大预设值可包括如下几种实现情况。In an embodiment, monitoring other search space sets one by one according to the relationship between search space sets or between CORESETs until reaching the maximum preset value may include the following implementation situations.

由于PDCCH可靠性增强中采用重复方案，即：从多个TRP传输的两个PDCCH候选的编码比特和DCI载荷(Payload)相同，因此，如果第一PDCCH候选解码成功后，为节约资源，可以将包含第二PDCCH候选第二搜索空间集合的优先级设置为低优先级。Since the repetition scheme is adopted in the PDCCH reliability enhancement, that is, the coded bits and the DCI payload (Payload) of the two PDCCH candidates transmitted from multiple TRPs are the same, therefore, if the decoding of the first PDCCH candidate is successful, in order to save resources, the The priority of the second search space set containing the second PDCCH candidates is set to low priority.

在一实施例中，可按照同类搜索空间集合中最后监测第二搜索空间集合的方案进行监测，其包括：In one embodiment, monitoring may be performed according to the scheme of monitoring the second set of search spaces last in the same set of search spaces, including:

S310：根据第一搜索空间集合或第一CORESET获取包括第二PDCCH候选的第二搜索空间集合，其中第一搜索空间集合和第二搜索空间集合为同一类型的搜索空间集合。S310: Acquire a second search space set including the second PDCCH candidate according to the first search space set or the first CORESET, where the first search space set and the second search space set are the same type of search space sets.

通过第一搜索空间集合或第一CORESET而得到第二搜素空间集合同上述一样，这里不再多做重复说明，从多个TRP传输的两个PDCCH候选的编码比特和DCI载荷(Payload)相同，因此包括第一PDCCH候选的第一搜索空间集合和包括第二PDCCH候选的第二搜索空间集合为同一类型的搜索空间集合。比如同为公共搜索空间集合或同为UE及搜索空间集合。Obtaining the second search space set through the first search space set or the first CORESET is the same as the above, and will not repeat the description here. The coded bits of the two PDCCH candidates transmitted from multiple TRPs are the same as the DCI payload (Payload). , so the first search space set including the first PDCCH candidate and the second search space set including the second PDCCH candidate are the same type of search space set. For example, the same is the common search space set or the same is the UE and the search space set.

S311：按照公共搜索空间集合、UE级搜索空间集合的顺序进行逐一监测，直到达到最大预设值，其中在同一类型的搜索空间集合中进行监测时按照索引值从小到大的顺序进行逐一监测，第二搜索空间集合在同一类型搜索空间集合中最后进行监测。S311: Perform monitoring one by one according to the order of the public search space set and the UE-level search space set until the maximum preset value is reached, wherein when monitoring is performed in the same type of search space set, the monitoring is performed one by one according to the order of index values from small to large, The second set of search spaces is last monitored in the set of search spaces of the same type.

由于公共搜索空间集合中的PDCCH携带的控制消息比UE级搜索空间集合中的PDCCH携带的控制消息重要，公共搜索空间集合比UE级搜索空间集合有更高优先级。无论第二搜索空间集合属于公共搜索空间集合还是UE级搜索空间集合，第二搜索空间集合在相同类型的搜索空间集合中优先级最低，但是如果第二搜索空间集合属于公共搜索空间集合，它比UE级搜索空间集合有更高有先级。Since the control messages carried by the PDCCH in the common search space set are more important than the control messages carried by the PDCCH in the UE-level search space set, the common search space set has higher priority than the UE-level search space set. Regardless of whether the second set of search spaces belongs to the set of common search spaces or the set of UE-level search spaces, the set of second search spaces has the lowest priority among the sets of search spaces of the same type, but if the set of second search spaces belongs to the set of common search spaces, it has lower priority than the set of search spaces of the same type. The UE-level search space set has higher priority.

具体地，第一搜索空间集合和第二搜索空间集合都属于公共搜索空间集合，则第二搜索空间集合的优先级是所有公共搜索空间集合中最低的，UE依照公共搜索空间集合索引值从小到大监测。如果除了第二搜索空间集合外，所有的公共搜索空间集合都已经被监测，并且未达到PDCCH候选与非重叠CCE个数最大数限制，UE将监测第二搜索空间集合。如果仍然未达到最大数目限制，按照UE级搜索空间集合索引值从小到大监测，直到达到最大数目限制。Specifically, if both the first search space set and the second search space set belong to the common search space set, the priority of the second search space set is the lowest among all the common search space sets, and the UE is based on the index value of the common search space set from small to Great monitoring. If all common search space sets have been monitored except the second search space set, and the maximum number of PDCCH candidates and non-overlapping CCEs has not been reached, the UE will monitor the second search space set. If the maximum number limit is still not reached, monitor according to the UE-level search space set index value from small to large until the maximum number limit is reached.

或者，第一搜索空间集合和第二搜索空间集合都属于UE级搜索空间集合，则第二搜索空间集合的优先级是所有UE级搜索空间集合中最低的。UE先监测公共搜索空间集合，如果监测了全部的公共搜索空间集合仍未达到PDCCH候选与非重叠CCE个数最大数限制，则将第二搜索空间集合从UE级搜索空间集合中挑出，按照UE级搜索空间集合索引值从小到大监测剩余的UE级搜索空间集合，直到达到最大数目限制，最后监测第二搜索空间集合。Alternatively, both the first search space set and the second search space set belong to the UE-level search space set, and the priority of the second search space set is the lowest among all UE-level search space sets. The UE first monitors the public search space set, and if the monitoring of all the public search space sets does not reach the maximum number of PDCCH candidates and non-overlapping CCEs, the second search space set is selected from the UE-level search space set, according to The UE-level search space set index value monitors the remaining UE-level search space sets from small to large until the maximum number limit is reached, and finally monitors the second search space set.

例如，请参阅图3，第一PDCCH候选属于COM SS Set#0，第二PDCCH候选属于COM SS Set#2，并且第一PDCCH候选与第二PDCCH候选有显式连接关系，搜索空间的监测顺序是Com SS Set#0、Com SS Set#1、Com SS Set#3、Com SS Set#2、UE SS Set#0、UE SS Set#1、UE SS Set#2、UE SS Set#3，直到达到最大数目限制。For example, referring to FIG. 3, the first PDCCH candidate belongs to COM SS Set#0, the second PDCCH candidate belongs to COM SS Set#2, and the first PDCCH candidate and the second PDCCH candidate have an explicit connection relationship, the monitoring order of the search space Yes Com SS Set#0, Com SS Set#1, Com SS Set#3, Com SS Set#2, UE SS Set#0, UE SS Set#1, UE SS Set#2, UE SS Set#3, until Maximum number limit reached.

在一实施例中，可在监测其他搜索空间时不再监测第二搜索空间集合的方案进行监测，其包括：In one embodiment, the solution of not monitoring the second set of search spaces can be monitored when monitoring other search spaces, which includes:

S320：根据所述第一搜索空间集合或第一CORESET获取包括所述第二PDCCH候选的第二搜索空间集合，其中第一搜索空间集合和第二搜索空间集合为同一类型的搜索空间集合。S320: Acquire a second search space set including the second PDCCH candidate according to the first search space set or the first CORESET, where the first search space set and the second search space set are the same type of search space sets.

通过第一搜索空间集合或第一CORESET而得到第二搜素空间集合同上述一样，这里不再多做重复说明。Obtaining the second search space set through the first search space set or the first CORESET is the same as the above, and will not be repeated here.

S321：按照公共搜索空间集合、UE级搜索空间集合的顺序进行逐一监测，直到达到最大预设值，其中在同一类型的搜索空间集合中进行监测时按照索引值从小到大的顺序进行逐一监测，且对第二搜索空间集合不进行监测。S321: Perform monitoring one by one according to the order of the public search space set and the UE-level search space set until the maximum preset value is reached, wherein when monitoring is performed in the same type of search space set, the monitoring is performed one by one according to the order of index values from small to large, And the second search space set is not monitored.

具体地，第一搜索空间和第二个搜索空间集合属于公共搜索空间集合或UE级搜索空间集合，直接将第二搜索空间集合挑出，不再监测第二搜索空间集合。在剩下的搜索空间集合中，按照先公共搜索空间集合再UE级搜索空间集合的顺序，并且在每个类型的搜索空间集合中，按照搜索空间集合索引值从小到大监测，直到达到PDCCH候选与非重叠CCE个数最大数限制。Specifically, the first search space and the second search space set belong to the common search space set or the UE-level search space set, the second search space set is directly picked out, and the second search space set is no longer monitored. In the remaining search space sets, in the order of the common search space set and then the UE-level search space set, and in each type of search space set, the index value of the search space set is monitored from small to large until the PDCCH candidate is reached. The maximum number of non-overlapping CCEs is limited.

例如，如图3所示，第一PDCCH候选属于Com SS Set#0，第二PDCCH候选属于Com SS Set#2，并且第一PDCCH候选与第二PDCCH候选有显式连接关系，搜索空间的监测顺序是Com SS Set#0、Com SS Set#1、Com SS Set#3、UE SS Set#0、UE SS Set#1、UE SS Set#2、UE SS Set#3，直到达到最大数目限制。For example, as shown in Figure 3, the first PDCCH candidate belongs to Com SS Set#0, the second PDCCH candidate belongs to Com SS Set#2, and the first PDCCH candidate and the second PDCCH candidate have an explicit connection relationship, the monitoring of the search space The order is Com SS Set#0, Com SS Set#1, Com SS Set#3, UE SS Set#0, UE SS Set#1, UE SS Set#2, UE SS Set#3, until the maximum number limit is reached.

当然，从多个TRP传输的两个PDCCH候选的编码比特与DCI载荷相同，并且可能需要对这两个PDCCH候选进行合并，再对合并后的PDCCH进行解码。因此，需要保证这两个PDCCH候选都被监测与解码。Of course, the coded bits of the two PDCCH candidates transmitted from multiple TRPs are the same as the DCI payload, and it may be necessary to combine the two PDCCH candidates, and then decode the combined PDCCH. Therefore, it is necessary to ensure that both PDCCH candidates are monitored and decoded.

在另一实施例中，可按照第二搜索空间集合有较高优先级的方案进行监测，其包括：In another embodiment, monitoring may be performed according to a scheme with a higher priority in the second search space set, including:

S330：根据第一搜索空间集合或第一CORESET获取包括第二PDCCH候选的第二搜索空间集合，其中第一搜索空间集合和第二搜索空间集合为同一类型的搜索空间集合。S330: Acquire a second search space set including the second PDCCH candidate according to the first search space set or the first CORESET, where the first search space set and the second search space set are the same type of search space sets.

S331：监测完第一搜索空间集合后，优先监测第二搜索空间集合。S331: After monitoring the first search space set, monitor the second search space set first.

第一搜索空间集合和第二搜索空间集合属于公共搜索空间集合或UE级搜索空间集合，在成功解码出第一PDCCH候选之后，继续完成第一搜索空间集合的监测，如果未达到最大数目限制，优先监测第二搜索空间集合。The first search space set and the second search space set belong to the common search space set or the UE-level search space set. After successfully decoding the first PDCCH candidate, continue to complete the monitoring of the first search space set. If the maximum number limit is not reached, The second set of search spaces is monitored preferentially.

S332：再按照公共搜索空间集合、UE级搜索空间集合的顺序进行逐一监测，直到达到最大预设值，其中在同一类型的搜索空间集合中进行监测时按照索引值从小到大的顺序进行逐一监测。S332: Perform monitoring one by one in the order of the public search space set and the UE-level search space set until the maximum preset value is reached, wherein when monitoring is performed in the same type of search space set, the monitoring is performed one by one in the order of index values from small to large .

在监测完第二搜索空间集合仍未达到最大数目限制，继续监测除了第二搜索空间集合之外的剩余的搜索空间集合，在这些剩余的搜索空间集合中，按照先公共搜索空间集合再UE级搜索空间集合的顺序，并且在每个类型的搜索空间集合中，按照搜索空间集合索引值从小到大监测，直到达到PDCCH候选与非重叠CCE个数最大数限制。After monitoring the second search space set and still not reaching the maximum number limit, continue to monitor the remaining search space sets except the second search space set. The order of the search space set, and in each type of search space set, the index value of the search space set is monitored from small to large until the maximum number of PDCCH candidates and non-overlapping CCEs is reached.

例如，如图3所示，第一PDCCH候选属于Com SS Set#0，第二PDCCH候选属于Com SS Set#2，并且第一PDCCH候选与第二个PDCCH候选有显式连接关系，搜索空间的监测顺序是Com SS Set#0、Com SS Set#2、Com SS Set#1、Com SS Set#3、UE SS Set#0、UE SS Set#1、UE SS Set#2、UE SS Set#3，直到达到最大数目限制。For example, as shown in Figure 3, the first PDCCH candidate belongs to Com SS Set#0, the second PDCCH candidate belongs to Com SS Set#2, and the first PDCCH candidate and the second PDCCH candidate have an explicit connection relationship, and the search space The monitoring sequence is Com SS Set#0, Com SS Set#2, Com SS Set#1, Com SS Set#3, UE SS Set#0, UE SS Set#1, UE SS Set#2, UE SS Set#3 , until the maximum number limit is reached.

在又一实施例中，根据第一PDCCH候选的相关信息对其他搜索空间集合进行逐一监测，直到达到最大预设值可包括如下几种实现情况。其中，第一PDCCH候选的相关信息为连接关系信息，连接关系信息包括控制信道单元起始位置、PDCCH候选索引值及聚合等级。In yet another embodiment, monitoring other search space sets one by one according to the relevant information of the first PDCCH candidate until the maximum preset value is reached may include the following implementation situations. Wherein, the related information of the first PDCCH candidate is connection relationship information, and the connection relationship information includes the starting position of the control channel element, the PDCCH candidate index value and the aggregation level.

从多个TRP传输的两个PDCCH候选的编码比特和DCI载荷相同，因此，如果第一PDCCH候选解码成功后，为使得资源最大化利用，可以将第二PDCCH候选解码优先级设置为低优先级。The coded bits and DCI payloads of the two PDCCH candidates transmitted from multiple TRPs are the same. Therefore, if the decoding of the first PDCCH candidate is successful, in order to maximize resource utilization, the decoding priority of the second PDCCH candidate can be set to a low priority .

在一实施例中，可按照同类搜索空间集合中最后监测第二PDCCH候选的方案进行监测，其包括：In one embodiment, the monitoring may be performed according to the last monitoring scheme of the second PDCCH candidate in the same search space set, which includes:

S340：根据第一PDCCH候选的相关信息获取第二PDCCH候选。S340: Acquire a second PDCCH candidate according to the related information of the first PDCCH candidate.

如上述，第一PDCCH候选的相关信息可能包括控制信道单元起始位置、PDCCH候选索引值及聚合等级，与之有显式连接关系的第二PDCCH候选可能具有相同的控制信道单元起始位置、PDCCH候选索引值及聚合等级三个信息中的一个或多个，UE可以根据这些信息直接监测第二PDCCH候选。As mentioned above, the relevant information of the first PDCCH candidate may include the starting position of the control channel element, the index value of the PDCCH candidate and the aggregation level, and the second PDCCH candidate with an explicit connection relationship with it may have the same starting position of the control channel element, One or more of the three pieces of information about the PDCCH candidate index value and the aggregation level, and the UE can directly monitor the second PDCCH candidate according to these pieces of information.

S341：按照公共搜索空间集合、UE级搜索空间集合的顺序进行逐一监测，直到达到最大预设值，其中在同一类型的搜索空间集合中进行监测时按照索引值从小到大的顺序进行逐一监测，且第二PDCCH候选在同一类型的搜索空间集合中最后进行监测。S341: Monitor one by one according to the order of the public search space set and the UE-level search space set, until the maximum preset value is reached, wherein when monitoring is performed in the same type of search space set, monitor one by one according to the order of index values from small to large, And the second PDCCH candidate is last monitored in the same type of search space set.

具体地，当第一搜索空间集合和第二搜索空间集合都属于公共搜索空间集合，监测完第一个PDCCH候选之后，则根据第一PDCCH候选与第二PDCCH候选之间的显式连接关系将第二PDCCH候选从第二搜索空间集合中挑出，放在所有公共搜索空间集合之后监测。UE依照公共搜索空间集合索引值从小到大监测，如果监测第二搜索空间集合，不对第二PDCCH候选监测。如果除了第二搜索空间集合所包含的第二PDCCH候选外，所有的公共搜索空间集合都已经被监测，并且未达到PDCCH候选与非重叠CCE个数最大数限制，UE将监测第二搜索空间集合所包含的第二PDCCH候选。如果仍然未达到最大数目限制，按照UE级搜索空间集合索引值从小到大监测，直到达到最大数目限制。Specifically, when both the first search space set and the second search space set belong to the common search space set, and after monitoring the first PDCCH candidate, according to the explicit connection relationship between the first PDCCH candidate and the second PDCCH candidate The second PDCCH candidate is picked out from the second set of search spaces and monitored after all the sets of common search spaces. The UE monitors according to the index value of the common search space set from small to large. If the second search space set is monitored, it does not monitor the second PDCCH candidate. If all common search space sets have been monitored except the second PDCCH candidates included in the second search space set, and the maximum number of PDCCH candidates and non-overlapping CCEs has not been reached, the UE will monitor the second search space set Included second PDCCH candidates. If the maximum number limit is still not reached, monitor according to the UE-level search space set index value from small to large until the maximum number limit is reached.

当第一搜索空间集合和第二搜索空间集合都属于UE级搜索空间集合，监测完第一个PDCCH候选之后，则根据第一PDCCH候选与第二PDCCH候选之间的显式连接关系将第二PDCCH候选从第二搜索空间集合中挑出，放在所有UE级搜索空间集合之后监测。UE先监测公共搜索空间集合，如果监测了全部的公共搜索空间集合仍未达到PDCCH候选与非重叠CCE个数最大数限制，则按照UE级搜索空间集合索引值从小到大监测剩余的UE级搜索空间集合，直到达到最大数目限制。其中，当监测第二个搜索空间集合时，不对第二个PDCCH候选监测。When both the first search space set and the second search space set belong to the UE-level search space set, after monitoring the first PDCCH candidate, the second PDCCH candidate is PDCCH candidates are picked from the second set of search spaces and monitored after all sets of UE-level search spaces. The UE first monitors the public search space set, and if it has not reached the maximum number of PDCCH candidates and non-overlapping CCEs after monitoring all the public search space sets, it monitors the remaining UE-level searches according to the UE-level search space set index value from small to large. Space collection until the maximum number limit is reached. Wherein, when monitoring the second search space set, the second PDCCH candidate is not monitored.

例如，请参阅图4，第一PDCCH候选属于Com SS Set#0，第二PDCCH候选(即：PDCCH候选#3)属于Com SS Set#2，并且第一PDCCH候选与第二PDCCH候选有显式连接关系，搜索空间的监测顺序是Com SS Set#0、Com SS Set#1、Com SS Set#2、Com SS Set#3、UE SS Set#0、UE SS Set#1、UE SS Set#2、UE SS Set#3，直到达到最大数目限制。其中，如果监测Com SS Set#2，先监测 PDCCH候选#0、PDCCH候选#1和PDCCH候选#2，暂不监测PDCCH候选#3。如果监测完Com SS Set#3仍未达到最大数目限制，再对PDCCH候选#3监测。For example, referring to FIG. 4, the first PDCCH candidate belongs to Com SS Set#0, the second PDCCH candidate (ie: PDCCH candidate #3) belongs to Com SS Set#2, and the first PDCCH candidate and the second PDCCH candidate have explicit Connection relationship, the monitoring order of the search space is Com SS Set#0, Com SS Set#1, Com SS Set#2, Com SS Set#3, UE SS Set#0, UE SS Set#1, UE SS Set#2 , UE SS Set#3, until the maximum number limit is reached. Wherein, if Com SS Set #2 is monitored, PDCCH candidate #0, PDCCH candidate #1 and PDCCH candidate #2 are first monitored, and PDCCH candidate #3 is not monitored for the time being. If the maximum number limit is not reached after monitoring Com SS Set #3, then monitor PDCCH candidate #3.

在另一实施例中，在监测其他搜索空间集合时，不再监测第二PDCCH候选的方案进行监测，其包括：In another embodiment, when monitoring other search space sets, the solution of the second PDCCH candidate is no longer monitored for monitoring, which includes:

S350：根据第一PDCCH候选的相关信息获取第二PDCCH候选相关信息。S350: Acquire the related information of the second PDCCH candidate according to the related information of the first PDCCH candidate.

根据第一PDCCH候选的相关信息获取第二PDCCH候选相关信息同上述，这里不再做说明。Obtaining the related information of the second PDCCH candidate according to the related information of the first PDCCH candidate is the same as the above, and will not be described here.

S351：按照公共搜索空间集合、UE级搜索空间集合的顺序进行逐一监测，直到达到最大预设值，其中在同一类型的搜索空间集合中进行监测时按照索引值从小到大的顺序进行逐一监测，且对第二PDCCH候选不进行监测。S351: Perform monitoring one by one according to the order of the public search space set and the UE-level search space set until the maximum preset value is reached, wherein when monitoring is performed in the same type of search space set, the monitoring is performed one by one in the order of index values from small to large, And the second PDCCH candidate is not monitored.

具体地，解码出第一PDCCH候选，继续监测第一搜索空间集合。当监测完第一搜索空间集合之后未达到PDCCH候选与非重叠CCE个数最大数目限制，继续监测剩余的搜索空间集合，在这些剩余的搜索空间集合中，按照先公共搜索空间集合再UE级搜索空间集合的顺序，并且在每个类型的搜索空间集合中，按照搜索空间集合索引值从小到大监测，直到达到最大数目限制。其中，如果监测第二搜索空间集合，不监测第二PDCCH候选。Specifically, the first PDCCH candidate is decoded, and the first search space set is continuously monitored. When the maximum number of PDCCH candidates and non-overlapping CCEs is not reached after monitoring the first search space set, continue to monitor the remaining search space sets. In these remaining search space sets, search the common search space set first and then the UE-level search. The order of the space sets, and in each type of search space set, the index value of the search space set is monitored from small to large until the maximum number limit is reached. Wherein, if the second search space set is monitored, the second PDCCH candidate is not monitored.

例如，如图4所示，第一PDCCH候选属于Com SS Set#0，第二PDCCH候选(即：PDCCH候选#3)属于Com SS Set#2，并且第一PDCCH候选与第二PDCCH候选有显式连接关系，搜索空间的监测顺序是Com SS Set#0、Com SS Set#1、Com SS Set#2、Com SS Set#3、UE SS Set#0、UE SS Set#1、UE SS Set#2、UE SS Set#3，直到达到最大数目限制。其中，如果监测Com SS Set#2，只监测PDCCH候选#0、PDCCH候选#1和PDCCH候选#2，不对PDCCH候选#3监测。For example, as shown in FIG. 4 , the first PDCCH candidate belongs to Com SS Set#0, the second PDCCH candidate (ie: PDCCH candidate #3) belongs to Com SS Set#2, and the first PDCCH candidate and the second PDCCH candidate are significantly different The monitoring sequence of the search space is Com SS Set#0, Com SS Set#1, Com SS Set#2, Com SS Set#3, UE SS Set#0, UE SS Set#1, UE SS Set# 2. UE SS Set #3 until the maximum number limit is reached. Wherein, if Com SS Set #2 is monitored, only PDCCH candidate #0, PDCCH candidate #1 and PDCCH candidate #2 are monitored, and PDCCH candidate #3 is not monitored.

当然，在基于第一PDCCH候选的相关信息进行其他搜索空间监测时，可能需要对这两个PDCCH候选进行监测合并，再对合并后的PDCCH进行解码。因此，需要保证这两个PDCCH候选都被监测与解码，可以将第二PDCCH候选解码优先级设置为较高优先级。Of course, when monitoring other search spaces based on the related information of the first PDCCH candidate, it may be necessary to monitor and combine the two PDCCH candidates, and then decode the combined PDCCH. Therefore, it is necessary to ensure that both PDCCH candidates are monitored and decoded, and the decoding priority of the second PDCCH candidate can be set to a higher priority.

在一实施例中，可按照在第二搜索空间中优先监测第二PDCCH候选的方案进行监测，其包括：In an embodiment, monitoring may be performed according to a scheme of preferentially monitoring the second PDCCH candidate in the second search space, which includes:

S362：再按照公共搜索空间集合、UE级搜索空间集合的顺序进行逐一监测，直到达到最大预设值，其中在同一类型的搜索空间集合中进行监测时按照索引值从小到大的顺序进行逐一监测，且在监测包含所述第二PDCCH候选的第二搜索空间集合时，优先监测第二PDCCH候选。S362: Perform monitoring one by one in the order of the public search space set and the UE-level search space set until the maximum preset value is reached, wherein when monitoring is performed in the same type of search space set, the monitoring is performed one by one according to the order of index values from small to large. , and when monitoring the second search space set including the second PDCCH candidate, the second PDCCH candidate is preferentially monitored.

当监测完第一搜索空间集合之后未达到PDCCH候选与非重叠CCE个数最大数目限制，继续监测剩余的搜索空间集合，在这些剩余的搜索空间集合中，按照先公共搜索空间集合再UE级搜索空间集合的顺序，并且在每个类型的搜索空间集合中，按照搜索空间集合索引值从小到大监测，直到达到最大数目限制。其中，在监测第二搜索空间集合时，优先监测第二PDCCH候选，再监测第二搜索空间集合中的其他PDCCH候选。When the maximum number of PDCCH candidates and non-overlapping CCEs is not reached after monitoring the first search space set, continue to monitor the remaining search space sets. In these remaining search space sets, search the common search space set first and then the UE-level search.

UE SS Set #3 until the maximum number limit is reached. Wherein, if Com SS Set #2 is monitored, PDCCH candidate #3 (ie: the second PDCCH candidate) is monitored first, and then PDCCH candidate #0, PDCCH candidate #1 and PDCCH candidate #2 are monitored.

在另一实施例中，可按照优先监测第二搜索空间集合，在第二搜索空间集合中优先监测第二PDCCH候选的方法进行监测，其方法包括：In another embodiment, monitoring may be performed according to a method of preferentially monitoring the second search space set and monitoring the second PDCCH candidate in the second search space set first, and the method includes:

S383：再按照公共搜索空间集合、UE级搜索空间集合的顺序进行逐一监测，直到达到最大预设值，其中在同一类型的搜索空间集合中进行监测时按照索引值从小到大的顺序进行逐一监测。S383: Perform monitoring one by one in the order of the public search space set and the UE-level search space set until the maximum preset value is reached, wherein when monitoring is performed in the same type of search space set, the monitoring is performed one by one according to the order of index values from small to large. .

当监测完第一个搜索空间集合的其他PDCCH候选之后未达到最大数目限制，继续监测除了第一搜索空间集合之外剩余的搜索空间集合，在这些剩余的搜索空间集合中，按照先公共搜索空间集合再UE级搜索空间集合的顺序，并且在每个类型的搜索空间集合中，按照搜索空间集合索引值从小到大监测，直到达到最大数目限制。其中，如果监测第二搜索空间集合，不再监测第二个PDCCH候选，直接监测第二搜索空间集合中的其他PDCCH候选。When the maximum number limit is not reached after monitoring the other PDCCH candidates in the first search space set, continue to monitor the remaining search space sets except the first search space set. The set is in the order of the UE-level search space set, and in each type of search space set, the search space set index value is monitored from small to large until the maximum number limit is reached. Wherein, if the second search space set is monitored, the second PDCCH candidate is no longer monitored, and other PDCCH candidates in the second search space set are directly monitored.
