Description

通信处理方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种通信处理方法、装置及存储介质。
背景技术
随着物联网业务的不断发展，比如视频监控，智能家居，可穿戴设备和工业传感监测等业务的普及。这些业务通常要求几十到100M的速率，同时对时延也有相对较高的要求，因此相关技术中的机器类通信(Machine Type Communication，MTC)，窄带物联网(Narrow band Internet of thing，NB-IoT)技术很难满足要求。故，提出了在5G新空口(New Radio，NR)中再设计一种新的终端类型用以来覆盖中端物联网设备的要求。在目前的3GPP标准化中，这种新的终端类型叫做Reduced capability UE或者简称为NR-lite。
针对NR-lite，网络设备需要做覆盖增强，同一个搜索空间也会在一个时隙中重复配置多次。在大多数情况下，网络设备配置多个搜索空间的重复配置不会超过物理下行控制信道(physical downlink control channel，PDCCH)传输的检测限制(盲检次数或者监测的不重叠覆盖的控制信道单元(control channel element，CCE)数量)，但是在某些情况下也会超过PDCCH传输的检测限制。比如在一个时隙(slot)中用户既需要监测公共搜索空间也需要监测用户专属的搜索空间，此时可能会超过PDCCH传输的检测限制。在多个搜索空间的重复配置传输超过PDCCH传输的检测限制时，需要进行搜索空间的丢弃(PDCCH dropping)。
相关技术中的，PDCCH dropping时，会优先丢弃搜索空间索引最大的搜索空间，并且在slot中索引最大的搜索空间被配置重复传输多次时，该slot中索引最大的搜索空间的所有重复传输都会被丢掉。

具体实施方式
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。
本公开实施例提供的接入方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括终端和网络设备。终端和网络设备之间通过无线资源进行信息的发送与接收。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网络设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网 络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网络设备。该无线接入网络设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
本公开实施例涉及的终端可以理解为是在5G NR中设计的新的终端类型：Reduced capability UE或者简称为NR-lite。本公开实施例中，将该新的终端称为5G NR-lite。
同长期演进(Long Term Evolution，LTE)中的物联网(Internet of Thing，IoT)设备类似，5G NR-lite通常需要满足如下要求：
-低造价，低复杂度
-一定程度的覆盖增强
-功率节省
由于目前的NR系统是针对高速率低时延等高端终端设计的，因此当前的设计无法满足NR-lite的上述要求。因此需要对目前的NR系统进行改造用以满足NR-lite的要求。比如，为了满足低造价，低复杂度等要求，可以限制NR-IoT的射频(Radio Frequency，RF)带宽，比如限制到5M Hz或者10M Hz,或者限制NR-lite的缓存(buffer)的大小，进而限制每次接收传输块的大小等等。针对功率节省，可能的优化方向是简化通信流程，减少NR-lite终端检测下行控制信道的次数等。
NR中PDCCH的基本组成单元是资源单元组(resource element group，REG),一个REG在频域上对应一个物理资源块(physical resource block，PRB)的大小(12个资源单元(resource element，RE))，在时域上对应一个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号的大小。6个REG会组成一个CCE(control channel element)。在目前的NR系统中，一个PDCCH可以由1、2、4、8、16个CCE构成。其中，一个PDCCH中包含的CCE的个数称为聚合程度。当一个PDCCH的信息比特固定的情况下，其聚合程度主要是由信道条件决定。当用户的信道条件较好时，可以使用较小的聚合程度。而当信道条件较差时，选择较大的聚合程度。另外，对于某个特定的聚合程度的PDCCH，协议支持多个候选传输位置。比如对于CCE＝4的PDCCH来说，可以有两个候选传输位置，网络设备和终端可以根据预设规则计算出这两个候选位置在所配置的控制资源集合中的CCE编号，比如为CCE#0～CCE#3，CCE#4～CCE#7。
在目前的NR中，网络设备可以给终端配置聚合程度以及每个聚合程度下PDCCH的候选传输位置，由于终端提前并不清楚网络设备会使用哪个聚合程度，又会在哪个候选传输位置上进行传输，也不知道网络设备传输的是哪种DCI格式，因此终端需要对PDCCH进行盲检。
在终端对PDCCH进行盲检时，需满足PDCCH传输检测限制。在NR中，协议规定在一个时隙(slot)内，在不同的子载波间隔参数(对应下表1中的u)下用户最大的盲检次数如下表1所示。
u 最大盲检次数
0 44
1 36
2 22
3 20
表1
同时，在一个slot内，用户所监测的non-overlapping的CCE总数也不能超过下表2 所示的数目。
u non-overlapping的CCE个数
0 56
1 56
2 48
3 32
表2
其中，终端在进行通信处理过程中，在一个slot中可以监测多个搜索空间，每个搜索空间都有对应的搜索空间索引(例如ID)。当一个slot中有多个搜索空间时，此时有可能用户PDCCH的盲检次数或者是监测的non-overlapping CCE总数会超过限制。此时协议允许终端丢掉某些搜索空间。丢掉的准则是只能丢掉终端专用的搜索空间，在终端的搜索空间中会优先丢掉搜索空间索引较大的搜索空间。并且当终端监测某个搜索空间导致超过PDCCH检测限制时，终端需要丢弃整个搜索空间。其中，终端检测搜索空间，并在累计检测的搜索空间传输次数超出PDCCH检测限制时丢弃搜索空间的方案称为PDCCH dropping。
一示例中，假设时隙(slot)内的最大盲检次数为44，搜索空间索引1对应的检测次数为20次，搜索空间索引2对应的检测次数为20，搜索空间索引3对应的检测次数为10。故，终端在进行通信处理过程中，按照搜索空间索引从小到大的顺序依次进行检测，检测到搜索空间3时，累计检测的搜索空间检测次数为50，检测到搜索空间索引3的传输会导致超过PDCCH检测限制(超过最大盲检次数44)，故终端会将搜索空间索引3丢弃。
在目前的NR-lite中，由于需要做覆盖增强，同一个搜索空间也会在一个slot中重复配置多次。在大多数情况下，网络设备配置多个搜索空间的重复不会超过PDCCH检测限制，但是在某些情况下会超过限制。比如在一个slot中用户既需要监测公共搜索空也需要监测用户专属的搜索空间，此时可能会超过限制。如果继续复用以前的PDCCH dropping原则，那么在一个slot中索引较大的搜索空间的所有重复传输都会被丢掉。
一示例中，假设时隙(slot)内的最大盲检次数为44，搜索空间索引1对应配置重复传输两次，每次传输的检测次数为8次。搜索空间索引2对应配置重复传输两次，每次传输的检测次数为8次。搜索空间索引3对应配置重复传输两次，每次传输的检测次数为8次。按照传统按照搜索空间索引从小到大顺序进行依次检测的方案，终端在进行通信处理过程中，按照搜索空间索引从小到大的顺序依次进行检测，检测到搜索空间3的第一次重复传输时，累计检测的搜索空间的检测次数40，未超出PDCCH检测限制(超过最大盲检 次数44)，但是检测到搜索空间索引3的第二次重复传输时，累计检测的搜索空间的检测次数48，超出PDCCH检测限制(超过最大盲检次数44)，终端会将搜索空间索引3第一次重复传输和第二次重复传输均丢弃。然而，搜索空间3的第一次重复传输已完成，是可以不丢弃的。
因此，按照已有PDCCH dropping，NR-lite在一个slot中重复配置搜索空间以进行重复传输时，若累计检测搜索空间超过PDCCH检测限制，可能会导致检测到的搜索空间索引最大的搜索空间的所有重复传输都会被丢掉，使得通信效率下降。
有鉴于此，本公开实施例提供一种通信处理方法，在该通信处理方法中，响应于同一传输时间单元(例如，一个slot)配置有重复传输的多个搜索空间，基于搜索空间索引和/或重复传输的搜索空间优化PDCCH dropping原则，使得传输更有效率。
图2是根据一示例性实施例示出的一种通信处理方法的流程图，如图2所示，通信处理方法用于终端中，包括以下步骤。
在步骤S11中，响应于同一传输时间单元中配置有重复传输的多个搜索空间，按照预设检测规则检测重复传输的搜索空间。
本公开实施例中配置重复传输搜索空间的传输时间单元可以是slot，也可以是子时隙(subslot)，当然也可以是其他的传输时间单元。本公开实施例以下以传输时间单元为slot为例进行说明。
本公开实施例中，基于搜索空间索引和/或重复传输的搜索空间，预先定义终端在进行搜索空间检测时的预设检测规则，以考量搜索空间索引和重复传输的搜索空间，提高通信效率。
在步骤S12中，响应于累计检测的搜索空间超过PDCCH检测限制，丢弃当前检测的搜索空间及未检测的搜索空间。
在本公开实施例中，丢弃当前检测的搜索空间及未检测的搜索空间的方式可以有很多种，例如：对接收到的搜索空间不再进行检测；再例如：将接收到的搜索空间删除。本公开实施例中，对此并不作出具体限定。
本公开实施例中PDCCH检测限制可以是最大盲检次数或者也可以是最大不重叠的CCE数量。
本公开实施例中，按照预设检测规则依次检测重复传输的多个搜索空间。当累计检测的搜索空间超过PDCCH检测限制时，丢弃当前检测的搜索空间及未检测的搜索空间。
本公开实施例以下结合实际应用对上述涉及的预设检测规则进行说明。
一种实施方式中，预设检测规则包括按照搜索空间索引从小到大的顺序，优先检测搜 索空间索引小的重复传输的搜索空间。或，预设检测规则包括按照搜索空间索引从大到小的顺序，优先检测搜索空间索引大的重复传输的搜索空间。这两种检测规则的原理类似，本公开实施中，以下是通过搜索空间索引从小到大的顺序的实施方式进行说明的；当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
其中，本公开实施例中按照搜索空间索引的大小依次判断，当一个搜索空间在一个slot中的所有重复传输都已经验证没有超过PDCCH检测限制时才能继续验证终端是否检测下一个搜索空间。响应于累计检测的搜索空间超过PDCCH检测限制，丢弃当前检测的搜索空间及未检测的搜索空间。通过此种方式可以保证重复传输已检测完成的搜索空间正常传输而不丢弃，提高通信效率。例如，上述示例中，假设时隙(slot)内的最大盲检次数为44，搜索空间索引1对应配置重复传输两次，每次传输的检测次数为8次。搜索空间索引2对应配置重复传输两次，每次传输的检测次数为8次。搜索空间索引3对应配置重复传输两次，每次传输的检测次数为8次。按照搜索空间索引从小到大的顺序依次检测重复传输的搜索空间，检测到搜索空间3的第二次重复传输的搜索空间时，累计检测的搜索空间检测次数为50，检测到搜索空间索引3的第二次重复传输的搜索空间会导致超过PDCCH检测限制(超过最大盲检次数44)，故终端会将搜索空间索引3的第二次重复传输的搜索空间，并不会丢弃搜索空间索引3的第一次重复传输的搜索空间，进而可提高通信效率。
另一种实施方式中，预设检测规则包括：按照时域传输先后顺序优先检测时域上先传输的搜索空间。当然，该实施方式可以配合前述的按照搜索空间索引顺序的实施例使用，即：对于同一搜索空间索引的不同重复传输的搜索空间，按照时域传输先后顺序优先检测时域上先传输的搜索空间。当然，该实施方式还可以独立使用。无论是单独使用还是配合前述的实施例一起使用，其检测规则的原理类似；本公开实施中，以下是配合前述的实施例一起使用的实施方式进行说明的；当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
本公开实施例中，终端按照搜索空间索引从小到大依次检测重复传输的搜索空间时，当具有相同索引的搜索空间重复传输时，需要在相同索引下的不同重复传输间定义丢弃优先级。比如，优先级可以是根据重复传输的时间先后(时域传输先后顺序)来确定。比如后传输的搜索空间重复优先级比较低，会被优先丢掉。
本公开另一个实施例中，预设检测规则包括：在不同重复传输间确定丢弃优先级。比如，优先级可以是根据重复传输的时间先后(时域传输先后顺序)来确定。比如后传输的搜索空间重复优先级比较低，会被优先丢掉。
本公开实施例中，在同一搜索空间索引中时域传输先后顺序依次接收和解调搜索空 间，只要再继续接收解调某一个搜索空间导致超过了PDCCH检测限制，这个搜索空间及后面的搜索空间都会被丢弃。即，当终端监测同一搜索空间索引中的某个搜索空间的部分重复传输没有超过PDCCH检测限制，但当监测所有重复传输超过PDCCH检测限制时，此时终端只会丢弃掉此搜索空间的部分重复传输，而不会丢掉所有重复传输。
图3是根据一示例性实施例示出的一种丢弃搜索空间的示例图。参阅图3所示，图中SSj和SSj+1分别代表两个搜索空间索引，其中SSj+1的搜索空间索引较大。图中R1、R2和R3分别为第一次重复传输、第二次重复传输和第三次重复传输的搜索空间的重复传输次数标识，其中，R3最大，R1最小。对于SSj和SSj+1两个搜索空间都进行了三次重复传输。图中箭头方向表示了被丢掉的搜索空间顺序。比如SSj+1的第三个重复传输会被首先丢掉，紧接着是SSj+1的第二个重复，以此类推。
再例如，上述示例中，假设时隙(slot)内的最大盲检次数为44，搜索空间索引1对应配置重复传输两次，每次传输的检测次数为8次。搜索空间索引2对应配置重复传输两次，每次传输的检测次数为8次。搜索空间索引3对应配置重复传输两次，每次传输的检测次数为8次。按照搜索空间索引从小到大的顺序依次检测重复传输的搜索空间，并在每一搜索空间内按照时域传输先后顺序优先检测时域上先传输的搜索空间。例如，针对搜索空间1先检测，当检测完成搜索空间1的第一次重复传输和第二次重复传输的搜索空间后，检测搜索空间索引2的第一次重复传输和第二次重复传输的搜索空间，以此类推，直至检测到搜索空间3的第二次重复传输的搜索空间时，累计检测的搜索空间检测次数为50，检测到搜索空间索引3的第二次重复传输的搜索空间会导致超过PDCCH检测限制(超过最大盲检次数44)，故终端会将搜索空间索引3的第二次重复传输的搜索空间，并不会丢弃搜索空间索引3的第一次重复传输的搜索空间，进而可提高通信效率。
又一种实施方式中，重复传输的搜索空间具有按照重复传输先后顺序且顺序递增的重复传输次数标识。所述预设检测规则包括按照重复传输次数标识递增的顺序，优先检测重复传输次数标识小的重复传输的搜索空间。或，所述预设检测规则包括按照重复传输次数标识递减的顺序，优先检测重复传输次数标识大的重复传输的搜索空间。这两种检测规则的原理类似，本公开实施中，以下是通过按照重复传输次数标识递增的顺序的实施方式进行说明的；当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。当然，该实施方式可以配合前述的按照搜索空间索引顺序的实施例使用；该实施方式还可以独立使用。无论是单独使用还是配合前述的实施例一起使用，其检测规则的原理类似；本公开实施中，以下是配合前述的实施例一起使用的实施方式进行说明的；当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
本公开实施例中，重复传输次数标识可以是重复传输的次数。例如，针对搜索空间索引1中第一次重复传输的搜索空间的重复阐述次数标识可以是1，针对搜索空间索引1中第二次重复传输的搜索空间的重复阐述次数标识可以是2。针对搜索空间索引2中第一次重复传输的搜索空间的重复传输次数标识可以是1，针对搜索空间索引2中第二次重复传输的搜索空间的重复传输次数标识可以是2。按照重复传输次数标识递增的顺序，优先检测重复传输次数标识小的重复传输的搜索空间，可以理解为是先对第一次重复传输的搜索空间(重复传输次数标识是1的搜索空间)进行检测，然后再对第二次重复传输的搜索空间(重复传输次数标识是2的搜索空间)进行检测，以此类推，直至累计检测的搜索空间超过PDCCH检测限制，丢弃当前检测的搜索空间及未检测的搜索空间。
又一种实施方式中，本公开实施例中预设检测规则除包括按照重复传输次数标识递增的顺序，优先检测重复传输次数标识小的重复传输的搜索空间，还包括对于具有相同重复传输次数标识且对应不同搜索空间索引的搜索空间，按照搜索空间索引从小到大的顺序，优先检测搜索空间索引小的搜索空间。
图4是根据一示例性实施例示出的一种丢弃搜索空间的示例图。参阅图4所示，图中SSj和SSj+1分别代表两个搜索空间的搜索空间索引，其中SSj+1的搜索空间索引较大。对于两个搜索空间都进行了三次重复传输，其中，图中R1、R2和R3分别为第一次重复传输、第二次重复传输和第三次重复传输的搜索空间的重复传输次数标识，其中，R3最大，R1最小。按照重复传输次数标识递增的顺序，优先检测重复传输次数标识小的重复传输的搜索空间，并且对于具有相同重复传输次数标识且对应不同搜索空间索引的搜索空间，按照搜索空间索引从小到大的顺序，优先检测搜索空间索引小的搜索空间，则是先检测重复传输次数标识为R1的搜索空间，并在R1中先检测SSj，然后再检测SSj+1。当检测完成重复传输次数标识为R1的搜索空间后，再检测传输次数标识为R2的搜索空间，并在R2中先检测SSj，然后再检测SSj+1。以此类推，直至累计检测的搜索空间超过PDCCH检测限制，丢弃当前检测的搜索空间及未检测的搜索空间。本公开实施例中当进行搜索空间丢弃时，搜索空间丢弃的先后顺序和搜索空间检测的顺序正好相反，例如图4中箭头方向表示了被丢掉的搜索空间顺序。比如重复传输次数标识为R3且搜索空间索引为SSj+1的搜索空间会被首先丢掉，紧接着是重复传输次数标识为R3且搜索空间索引为SSj的搜索空间会被第二个丢掉，以此类推。
本公开实施例中又一种实施方式中，预设检测规则包括按照时域传输先后顺序优先检测时域上先传输的搜索空间。
一示例中，假设时隙(slot)内的最大盲检次数为44，在时域传输先后顺序上依次传 输搜索空间1、搜索空间2……搜索空间N。其中，搜索空间1、搜索空间2……搜索空间N中每个搜索空间对应的检测次数8。按照时域传输先后顺序优先检测时域上先传输的搜索空间，则先检测搜索空间1，然后检测搜索空间2，以此类推，直至累计检测的搜索空间超过PDCCH检测限制，丢弃当前检测的搜索空间及未检测的搜索空间。例如，本示例中，检测到搜索空间5时，累计检测的搜索空间次数为40，未超出PDCCH检测限制(最大盲检次数44)，而当检测到搜索空间6时，累计检测的搜索空间次数为48，超出PDCCH检测限制(最大盲检次数44)，则丢弃搜索空间6以及后续未检测的搜索空间。
本公开实施例中，终端丢弃了搜索空间后，一方面可以停止监测丢弃的搜索空间；或者继续监测网络设备补发的搜索空间，直至搜索空间的重复传输次数满足配置的重复传输次数。
图5是根据一示例性实施例示出的一种通信处理方法的流程图，如图5所示，通信处理方法用于网络设备中，包括以下步骤。
在步骤S21中，响应于同一传输时间单元中需重复传输多个搜索空间，按照预设传输规则重复传输搜索空间。
其中，预设传输规则基于搜索空间索引和/或重复传输的搜索空间确定。
本公开实施例中配置重复传输多个搜索空间的传输时间单元可以是slot，也可以是子时隙(subslot)，当然也可以是其他的传输时间单元。本公开实施例以下以传输时间单元为slot为例进行说明。
本公开实施例中，基于搜索空间索引和/或重复传输的搜索空间，预先定义网络设备传输搜索空间的传输规则。网络设备按照预设传输规则重复传输搜索空间，以考量搜索空间索引和重复传输的搜索空间，提高通信效率。
在步骤S22中，响应于累计传输的搜索空间超过物理下行控制信道传输限制，丢弃当前传输的搜索空间及未传输的搜索空间。
在本公开实施例中，丢弃当前传输的搜索空间及未传输的搜索空间的方式可以有很多种，例如：对传输的搜索空间不再进行传输；再例如：将未传输的搜索空间删除。本公开实施例中，对此并不作出具体限定。
本公开实施例以下结合实际应用对上述涉及的预设检测规则进行说明。
一种实施方式中，预设传输规则包括按照搜索空间索引从小到大的顺序，优先传输搜索空间索引小的搜索空间。或，预设传输规则包括按照搜索空间索引从大到小的顺序，优先传输搜索空间索引大的重复传输的搜索空间。这两种检测规则的原理类似，本公开实施中，以下是通过搜索空间索引从小到大的顺序的实施方式进行说明的；当然，本领域内技 术人员可以理解，这样的举例说明并非对本公开实施例的限定。
其中，本公开实施例中按照搜索空间索引的大小依次判断，当一个搜索空间在一个slot中的所有重复传输都已经验证没有超过PDCCH检测限制时才能继续验证终端是否检测下一个搜索空间。响应于累计传输的搜索空间超过PDCCH检测限制，丢弃当前传输的搜索空间及未传输的搜索空间。通过此种方式可以保证重复传输已传输完成的搜索空间正常传输而不丢弃，提高通信效率。
本公开实施例另一种实施方式中，预设传输规则包括按照时域传输先后顺序优先传输时域上先传输的搜索空间。当然，该实施方式可以配合前述的按照搜索空间索引顺序的实施例使用，即：对于同一搜索空间索引的不同重复传输的搜索空间，按照时域传输先后顺序优先传输时域上先传输的搜索空间。当然，该实施方式还可以独立使用。无论是单独使用还是配合前述的实施例一起使用，其传输规则的原理类似；本公开实施中，以下是配合前述的实施例一起使用的实施方式进行说明的；当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
本公开实施例中，网络设备按照搜索空间索引从小到大依次传输重复传输的搜索空间时，当具有相同索引的搜索空间重复传输时，需要在相同索引下的不同重复传输间定义丢弃优先级。比如，优先级可以是根据重复传输的时间先后(时域传输先后顺序)来确定。比如后传输的搜索空间重复优先级比较低，会被优先丢掉。
本公开另一个实施例中，预设检测规则包括：在不同重复传输间确定丢弃优先级。比如，优先级可以是根据重复传输的时间先后(时域传输先后顺序)来确定。比如后传输的搜索空间重复优先级比较低，会被优先丢掉。
本公开实施例中，在同一搜索空间索引中时域传输先后顺序依次传输搜索空间，只要再继续传输某一个搜索空间导致超过了PDCCH检测限制，这个搜索空间及后面的搜索空间都会被丢弃传输。即，当终端监测同一搜索空间索引中的某个搜索空间的部分重复传输没有超过PDCCH检测限制，但当监测所有重复传输超过PDCCH检测限制时，此时终端只会丢弃掉此搜索空间的部分重复传输，而不会丢掉所有重复传输。
本公开实施例又一种实施方式中，重复传输的搜索空间具有按照传输先后顺序且顺序递增的重复传输次数标识。预设传输规则包括按照重复传输次数标识递增的顺序，优先传输重复传输次数标识小的搜索空间。或，所述预设传输规则包括按照重复传输次数标识递减的顺序，优先传输重复传输次数标识大的重复传输的搜索空间。这两种传输规则的原理类似，本公开实施中，以下是通过按照重复传输次数标识递增的顺序的实施方式进行说明的；当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。当 然，该实施方式可以配合前述的按照搜索空间索引顺序的实施例使用；该实施方式还可以独立使用。无论是单独使用还是配合前述的实施例一起使用，其传输规则的原理类似；本公开实施中，以下是配合前述的实施例一起使用的实施方式进行说明的；当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
本公开实施例中，重复传输次数标识可以是重复传输的次数。按照重复传输次数标识递增的顺序，优先传输重复传输次数标识小的重复传输的搜索空间，可以理解为是先传输第一次重复传输的搜索空间(重复传输次数标识是1的搜索空间)，然后再传输第二次重复传输的搜索空间(重复传输次数标识是2的搜索空间)进行检测，以此类推，直至累计传输的搜索空间超过PDCCH检测限制，丢弃当前传输的搜索空间及未传输的搜索空间。
又一种实施方式中，本公开实施例预设传输规则包括按照重复传输次数标识递增的顺序，优先传输重复传输次数标识小的搜索空间，并且对于具有相同重复传输次数标识且对应不同搜索空间索引的搜索空间，按照搜索空间索引从小到大的顺序，优先传输搜索空间索引小的搜索空间。
又一种实施方式中，本公开实施例预设传输规则包括按照时域传输先后顺序优先传输时域上先传输的搜索空间。
本公开实施例中PDCCH传输限制包括物理下行控制信道的最大盲检次数或最大不重叠的CCE数。
本公开实施例中，网络设备丢弃传输的搜索空间后，可以选择不再补发丢弃的搜索空间；或者补发丢弃的搜索空间，直至搜索空间的重复传输次数满足配置的重复传输次数。
可以理解的是，本公开实施例中，网络设备在进行搜索空间重复传输过程中对搜索空间进行丢弃的预设传输规则的设定过程与网络设备进行搜索空间检测并丢弃的预设检测规则类似，本公开实施例在此不再详述，对于描述不够详尽的地方可以参阅终端侧进行预设检测规则设置的过程。
进一步可以理解的是，本公开实施例提供的通信处理方法也可以适用于网络设备和终端进行交互实现搜索空间丢弃的过程，具体实施过程可以参阅上述实施例涉及的终端侧或网络侧实现搜索空间丢弃的实施过程，本公开实施例在此不再详述。
