Description

确定搜索空间的方法及无线装置
本申请要求于2017年11月10日提交中国专利局、申请号为201711108175.4、申请名称为“确定搜索空间的方法及无线装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种确定搜索空间的方法及无线装置。
背景技术
在长期演进(long term evolution，LTE)系统中，终端设备通过物理下行控制信道(physical downlink control channel，PDCCH)接收下行控制信令(downlink control information，DCI)。DCI用于指示终端设备接收下行数据、发送上行数据以及调整发射功率等。
网络设备为终端设备配置控制资源集合，该控制资源集合包括用于构成PDCCH的控制信道单元(control channel element，CCE)。终端设备确定控制资源集合中的搜索空间，所述搜索空间为候选PDCCH的集合，并在所述搜索空间内检测用于传输DCI的PDCCH。
目前现有确定搜索空间的方法主要适用于网络设备为终端设备配置的控制资源集合为一个或两个的场景且终端设备的数量受限。在未来演进网络中，网络设备为终端设备配置的控制资源集合可能会超过两个，而且终端设备的数量还会更多，因此现有的确定搜索空间的方法无法适用于未来演进网络。
发明内容
本申请提供一种确定搜索空间的方法及无线装置，用于解决现有的确定搜索空间的方法无法适用于未来演进网络的问题。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供一种无线装置确定搜索空间的方法，所述方法包括：获取第二参数以及控制资源集合对应的第一参数，所述第一参数为不等于39827、39829和65537的正整数，所述第二参数等于65537或者为不等于65537的素数；以及，根据所述第一参数和所述第二参数，确定所述控制资源集合的搜索空间。
这样，由于第一参数为不等于39827、39829和65537的整数，所述第二参数等于65537或者为不等于65537的素数，即第一参数和第二参数为当前网络限定的取值(即39827、39829、65537)之外的其他取值，使得第一参数和第二参数的取值适应未来网络的演进，并在满足未来网络中多种需求下，降低搜索空间中的控制信道发生阻塞的概率。
在第一方面的一种可能实现方式中，所述方法还包括：获取控制资源集合的编号。上述获取控制资源集合对应的第一参数，包括：根据控制资源集合的编号，确定所述第一参数。从而，无线装置能够获取到控制资源集合对应的第一参数。
在第一方面的一种可能实现方式中，上述根据控制资源集合的编号，确定所述参数， 包括：根据预设对应关系，确定控制资源集合的编号对应的第一参数，其中，所述预设对应关系包括控制资源集合的编号以及控制资源集合的编号对应的第一参数。示例性的，控制资源集合的编号可以为0,1,2,3……。

多个无线设备可以执行相同或者不同的业务。例如，移动宽带业务，增强移动宽带(enhanced mobile broadband，eMBB)业务，终端设极高可靠极低时延通信(ultra-reliable and low-latency communication，URLLC)业务等等。
进一步地，上述接入网设备102的一种可能的结构示意图可以如图2所示。该接入网设备102能够执行本申请实施例提供的方法。其中，该接入网设备102可以包括：控制器或处理器201(下文以处理器201为例进行说明)以及收发器202。控制器/处理器201有时也称为调制解调器处理器(modem processor)。调制解调器处理器201可包括基带处理器(baseband processor，BBP)(未示出)，该基带处理器处理经数字化的收到信号以提取该信号中传达的信息或数据比特。如此，BBP通常按需或按期望实现在调制解调器处理器201内的一个或多个数字信号处理器(digital signal processor，DSP)中或实现为分开的 集成电路(integrated circuit，IC)。
收发器202可以用于支持接入网设备102与终端设备之间收发信息，以及支持终端设备之间进行无线电通信。所述处理器201还可以用于执行各种终端设备与其他网络设备通信的功能。在上行链路，来自终端设备的上行链路信号经由天线接收，由收发器202进行调解，并进一步处理器201进行处理来恢复终端设备所发送的业务数据和/或信令信息。在下行链路上，业务数据和/或信令消息由终端设备进行处理，并由收发器202进行调制来产生下行链路信号，并经由天线发射给UE。所述接入网设备102还可以包括存储器203，可以用于存储该接入网设备102的程序代码和/或数据。收发器202可以包括独立的接收器和发送器电路，也可以是同一个电路实现收发功能。所述接入网设备102还可以包括通信单元204，用于支持所述接入网设备102与其他网络实体进行通信。例如，用于支持所述接入网设备102与核心网的网络设备等进行通信。

在介绍本申请实施例提供的方法之前，先对本申请实施例涉及的相关术语进行简单的介绍。
控制信道由一个或多个CCE构成，用于承载控制信息，例如包括：PDCCH。
控制信道的聚合等级的大小对应组成控制信道的CCE的个数。例如：PDCCH的聚合等级为组成PDCCH的CCE的个数，PDCCH的聚合等级为集合{1,2,4,8,16,32}中的任意一个。
搜索空间为候选控制信道的集合。所述搜索空间可分为：公共搜索空间(common search space)和UE特定的搜索空间(UE-specific search space)。公共搜索空间用于传输Paging、RA Response、系统信息等相关的控制信息。UE特定的搜索空间用于与DL-SCH、UL-SCH等相关的控制信息。当然，公共搜索空间也可以用于传输属于某个特定UE的控制信息，本申请实施例对此不作任何限制。
时间单元由时域上的至少一个时间间隔(time interval，TI)组成，这里的TI可以是LTE系统中的传输时间间隔(transmission time interval，TTI)，也可以是符号级短TTI，或高频系统中的大子载波间隔的短TTI，也可以是5G系统中的时隙(slot)、微型时隙(mini-slot)或一个OFDM符号等。本申请实施例对此不做限定。
另外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请实施例的描述中，除非另有说明，“多 个”的含义是两个或两个以上。本申请实施例中的“一个”意味着单个个体，并不代表只能是一个个体，不能应用于其他个体中。例如，本申请实施例中的“一个终端设备”指的是针对某一个终端设备，并不意味着只能应用于一个特定的终端设备。本申请中，术语“系统”可以和“网络”相互替换使用。本申请中的“一个实施例”(或“一个实现”)或“实施例”(或“实现”)的引用意味着连同实施例描述的特定特征、结构、特点等包括在至少一个实施例中。因此，说明书的各个位置中出现的“在一个实施例中”或“在实施例中”，并不表示都指代相同实施例。进一步地，本申请实施例中的“A和/或B”和“A和B中至少一个”的情况下使用术语“和/或”和“至少一个”包括三种方案中的任一种，即，包括A但不包括B的方案、包括B不包括A的方案、以及两个选项A和B都包括的方案。作为另一示例，在“A、B、和/或C”和“A、B、和/或C中至少一个”的情况下，这样的短语包括六种方案中的任一种，即，包括A但不包括B和C的方案、包括B不包括A和C的方案、包括C但不包括A和B的方案，包括A和B但不包括C的方案，包括B和C但不包括A的方案，包括A和C但不包括B的方案，以及三个选项A、B和C都包括的方案。如本领域和相关领域普通技术人员所容易理解的，对于其他类似的描述，本申请实施例均可以按照上述方式理解。
当前，接入网设备发送承载控制信息的控制信道。相应的，终端设备在控制资源集合中的搜索空间检测控制信道，以获取相关的控制信息。接入网设备或终端设备确定搜索空间，即确定至少一个候选控制信道所对应的CCE编号。
而对于某个候选控制信道来说，可以通过如下公式(1)，确定该候选控制信道所对应的ECCE编号。

其中，L表示候选控制信道的聚合等级，i∈{0,1,2,3,4,......,L-1}，t为时间单元的编号，例如，在LTE中，所述时间单元为子帧。N CCE,p,t为控制资源集合包括的CCE的个数。

Figure PCTCN2018115093-appb-000003
如果终端设备配置了载波指示字段(Carrier Indicator Field，CIF)值n CI，则b＝n CI；如果未配置CIF值，b＝0。
Y p,t＝(A p×Y p,t-1)mod D，Y p,k为与控制资源集合p以及t相关的参数，A p为控制资源集合p对应的参数，Y p,-1＝n NRTI≠0，n NRTI为终端设备的无线网络临时标识(radio network temporary identity，RNTI)的取值。在当前网络中，标准中规定接入网设备最多为终端设备配置两个控制资源集合，即p∈{0,1}，A 0＝39827，A 1＝39829，D＝65537。
下面对上述参数A 0＝39827，A 1＝39829和D＝65537不适用于未来演进网络的原因进行分析。
1)在当前网络中，接入网设备最多为终端设备配置两个控制资源集合；而在未来演进网络中，接入网设备可能会为终端配置超过两个控制资源集合。但是，当前网络中A p仅存在两个取值(39827和39829)，这种情况下，在超过两个的控制资源集合中，如果仍沿用目前提供的A p的取值，必然存在两个控制资源集合对应的A p相同。而如果两个控制资源集合对应的A p相同，则对于一个终端设备来说，其在两个控制资源集合上的候选控制信道会有重叠，从而造成控制信道阻塞，影响终端设备正常接收控制信息。
2)在当前网络中，终端设备的无线网络临时标识为一个16位比特的序列，因此n NRTI∈{1,2,3,4,......,65536}。但是，在未来演进网络中，终端设备的无线网络临时标识可能为大于16位比特的序列，因此n NRTI的取值范围大于65536，这种情况下，如果D还是等于65537，则在同一个控制资源集合中至少存在两个终端设备的Y p,k相同，进而导致在同一个控制资源集合中，两个终端设备的候选控制信道重叠，从而造成控制信道阻塞，影响终端设备正常接收控制信息。
可见，由于未来演进网络中的应用场景与当前网络中的应用场景存在不同，因此，当前网络设定的A 0＝39827、A 1＝39829以及D＝65537不适用于未来演进网络的搜索空间确定过程中。

一种可能的实现方式中，获取所述控制资源集合的编号，然后，根据所述控制资源集合的编号，确定所述第一参数。
所述控制资源集合是接入网设备为终端设备配置的M个控制资源集合中的一个，所述M小于等于Q，所述Q为所述终端设备可配置的控制资源集合的最大个数。其中，M、Q均为正整数。示例性的，Q个控制资源集合的编号的可是表示为：{0,1,2,3,4,......,Q-1}。当然，Q个控制资源集合的编号也可以采用其他实现方式，本申请实施例对此不作任何限制。可以理解的是，接入网设备根据终端设备上报的接入带宽的大小、所支持的最大的带宽区域(bandwidth part，BWP)的个数，或者其他参数，确定终端设备对应Q的取值。
实际应用中，当该方法应用在终端设备时，终端设备接收接入网设备发送的无线资源控制(radio resource control，RRC)信令，所述RRC信令中包括所述控制资源集合的编号。当该方法应用在接入网设备时，接入网设备根据终端设备的RNTI，确定控制资源集合的编号。当然，接入网设备也可以采用其他方法，确定控制资源集合的编号，本申请实施例对此不作任何限制。
值得说明的是，本步骤中RRC信令发送的动作可以由上述接入网设备102的收发器202来实现，当然，也可以是上述接入网设备102的处理器201来控制收发器202实现。本步骤中RRC信令接收的动作可以由上述终端设备101的收发器301来实现，当然，也可以是上述终端设备101的调制解调器处理器304来控制收发器301实现。
在获取控制资源集合的编号后，根据第一预设对应关系，确定所述控制资源集合的编号对应的所述第一参数。
在第一预设对应关系的一种可能实现方式中，所述第一预设对应关系包括所述控制资源集合的编号以及所述控制资源集合的编号对应的所述第一参数。示例性的，所述第一预设对应关系可以如表一所示。

一种可能的实现方式中，终端设备获取第一集合中的一个元素A′，并根据A′的取值获取第一参数；所述A′可以标准中预定义的一个取值。
可选的，所述第一参数为上述第一集合中的一个元素。第一参数满足如公式(2)所示关系：
A＝(A′ q)modD      (2)
其中，A表示所述第一参数，D表示所述第二参数，A′表示所述第三参数，q为与D-1互质的整数。第三参数可以为标准中预定义的一个取值。
一种可能的实现方式中，终端设备获取A′，并根据A′的取值获取第一参数。
例如，标准中预定义A′＝39827，D＝65537；终端设备根据第一参数A和A′的关系获取第一参数；其中，D-1＝65536，而与65536互为质数的取值包括如下取值集合中的一个：{1,3,5,7,9}；则第一参数A＝(39827 3)mod65537＝50028，其中A为所述第一集合中的一个元素。
一种可能的实现方式中，终端设备获取控制资源集合的编号p，和预定义的参数A′并根据A′的取值获取控制资源集合编号p对应的第一参数。
例如，标准中预定义A′＝39827，D＝65537；终端设备获取控制资源集合的编号p，其中编号p为集合中{1,2,3}的一个取值，第一参数可根据如下关系获得:
A＝(A′ q)modD   (3)
其中，q＝2 p+1。具体的，对于编号p＝1的控制资源集合对应的第一参数A＝(39827 3)mod65537＝50028；类似的对于p为其他取值时，第一参数可根据公式(3)获得。
402、根据所述第一参数和所述第二参数，确定所述控制资源集合的搜索空间。
一种可选的实现方式中，根据如下公式(4)，确定所述控制资源集合对应的搜索空间：
Y k＝(A*Y k-1)modD   (4)
其中，k表示时间单元的编号，Y k表示与时间单元k对应的变量，Y k-1表示与时间单元k-1对应的变量，A表示所述第一参数，D表示所述第二参数。
需要说明的是，针对上述公式中的A与D，本申请实施例并不限制其与第一参数、第二参数的对应关系。举例来说，当第二参数等于65537时，第二参数可以表示为A。
值得说明的是，上述公式(4)可变形公式(5)为：
Y k＝(A k+1*Y -1)modD     (5)
其中Y -1＝n RNTI≠0，n RNTI为终端设备的RNTI的取值。
示例性的，当A＝39839，D＝65537，n RNTI＝1时，Y k的取值范围为集合{39839,36392,11374,5968,56453,63375,48237,30433,51324,7973}。
示例性的，当A＝39839，D＝65537，n RNTI＝2时，Y k的取值范围为集合{14141,7247,22748,11936,47369,61213,32937,60866,37111,15946}。
另外，在公式(4)中，若A不是D的原根，(A*Y k-1)modD的周期性会小于D，即Y k的取值个数会小于D。举例来说，在当前网络中A＝39829、D＝65537、n NRTI∈{1,2,3,4,......,65536}，此时，Y k的取值仅包括32768个不同的取值。这种情况下，同一个控制资源集合中很可能存在两个终端设备的Y p,k相同，进而导致在同一个控制资源集合中，两个终端设备的候选控制信道重叠，从而造成控制信道阻塞。因此，为了降低控制信道阻塞的概率，A为D的原根。
值得说明的是，本步骤中确定搜索空间的动作可以由上述接入网设备102的处理器201来实现。或者，本步骤中确定搜索空间的动作可以由上述终端设备101的调制解调器处理器304来实现。
可选的，当应用于接入网设备时，接入网设备在根据步骤402确定的所述搜索空间后，在所述搜索空间中的一个或多个候选控制信道上发送控制信息，所述控制信息可用于对终端设备的上下行资源分配以及功率控制等。在5G系统中，所述控制信息为下行控制信息。 相应地，终端设备在确定所述控制资源集合的搜索空间后，会在所述搜索空间中检测至少一个候选控制信道以获取控制信息。该过程的具体实现可参考现有技术，此处不再赘述。
可选的，当应用于终端设备时，终端设备在根据步骤402确定的所述搜索空间中检测至少一个候选控制信道以获取控制信息，该过程的具体实现可参考现有技术，此处不再赘述。
