Abstract

Description

无线通信系统中的装置和方法 技术领域
本公开涉及无线通信技术，具体地，涉及能够协调小区侧的周期性非连续发射(DTX)模式与用户设备侧的周期性非连续接收(DRX)模式的无线通信系统中的装置和方法，其中，周期性非连续发射模式的每一周期包括激活时段和休眠时段，并且小区在激活时段期间为用户设备提供服务。
背景技术
随着网络覆盖与数据需求的飞速发展，移动网络的规模不断扩大，网络设备、基站及动力系统数量成倍增加，无线通信网络的能耗问题已经成为业界关注的焦点。小区中的基站是无线通信网络中主要的耗能设备，随着蜂窝系统通信系统的用户数目和通信容量日剧增大，基站的数目还会快速增加，因此降低基站的能量消耗是实现绿色通信的关键。
对于基站侧的节能，可以如终端侧的DRX机制一样，基站侧也可以根据实际的容量需求进行动态开关，从而合理地分配功耗，以达到节约能源的目标。对于这些内容，3GPP在RAN1的小小区增强(small cell enhancements)中有相应的讨论，亦即，小小区开关(small cell on/off)。
在3GPP的讨论中，小小区开关的实现方式有很多种，例如，基于数据包到达、用户到达等，但由于数据包的到达以及用户到达都是随机的，在这样的情况下，小小区决定进行开启、关闭转换的时间点也往往是随机的。因此，小小区休眠会对传统的用户造成性能损失，同时小小区开/关转换时间的长度，也会进一步影响开/关机制的性能。
DRX机制是用户在能耗与快速响应之间的一个均衡。DRX使用户只需周期性地对控制信道进行监测，通过非激活计时器(inactivity timer)或者设置较短的DRX计时器应对数据的突发性。在传统的DRX机制中，小区侧默认为是始终开启的，而在小小区可进行休眠的场景下，小区在某个时刻的开关状态是不确定的。如果在终端侧处于DRX模式中的激活时段以期望从小区接收数据而小区侧此时处于休眠时段时，则无法实现期望 的通信。因此，需要协调小区侧的开/关与终端侧的DRX模式。

鉴于以上问题，本公开的目的之一是提供小区侧的开/关与用户设备侧的非连续接收之间的协调方法，旨在在保障用户的服务性能的同时尽可能节省系统功耗。具体地，小区侧可配置周期性的休眠策略，即，周期性非连续发射(DTX)模式。类似用户侧的周期性DRX机制，如果小区侧的DTX机制配置有固定的开/关周期，那么可以通过设置使得小区内的用户设备的DRX周期与小区的DTX周期保持兼容以对传统用户进行支持。此外，用户设备也可以在了解小区DTX周期的前提下，提前进行通信前的准备，从而减少了小区开/关的转换时间。

根据本公开的另一优选实施例，分配单元进一步被配置成使得在开启了小区的周期性非连续发射模式之后，如果用户设备到来了实时性强和/或数据传输量大的业务并且当前配置的周期性非连续发射模式无法满足 用户设备当前的业务需求，则将小区的周期性非连续发射模式的一个周期内的用于一组或多组用户设备的激活时段分配给该用户设备以为用户设备服务。
根据本公开的另一优选实施例，该无线通信系统中的装置还可包括：服务单元，被配置成如果小区无法支持用户设备的业务，则使得小区将该业务卸载给没有开启周期性非连续发射模式的小区，或者对于能够支持载波聚合和/或双连接场景的用户设备，则利用不同小区的周期性非连续发射模式的周期内的激活时段协同为该用户设备服务。
根据本公开的另一优选实施例，小区配置单元进一步被配置成使得如果在预定时长内小区的平均负载状况高于预定阈值和/或如果小区内某些用户设备的业务无法通过周期性非连续发射模式实现，则关闭小区的周期性非连续发射模式。

在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或处理步骤，而省略了与本公开关系不大的其它细节。
以下将参照图1至图11描述本公开的实施例。
首先，将参照图1描述根据本公开的实施例的无线通信系统中的装置的功能配置示例。图1是示出根据本公开的实施例的无线通信系统中的装置的功能配置示例的框图。
如图1所示，根据本实施例的无线通信系统中的装置100可包括小区配置单元102和用户设备配置单元104。接下来将详细描述各个单元的功能配置示例。
小区配置单元102可被配置成根据小区的负载状况和/或小区间的干扰状况而控制小区的周期性非连续发射模式并且配置周期性非连续发射模式的包括周期的参数。其中，小区的周期性非连续发射模式的每一周期包括激活时段和休眠时段，小区在激活时段期间为用户设备提供服务。
应理解，在休眠时段期间，可以与小小区开关中的概念一样，当一个小区关闭时，出于节能的目的,它将关闭大部分的射频功能,不再发送保证用户设备可以正常通信的参考信号，例如用于小区测量的参考信号(例如，小区参考信号(CRS)、信道状态信息-参考信号(CSI-RS)等)或者用于数据解调的参考信号(例如，解调参考信号(DMRS)等)。然而，为了使得用户可以发现这样的小区，在未来的标准中也考虑引入专用的小区发现信号(DRS)，使得在休眠时段(即小区被关闭期间)也继续发送该小区发现信号。
应指出，与用户设备侧的DRX模式相对，DTX模式是针对小区侧而言的。在本公开中，由于DRX模式的周期与DTX模式的周期具有兼容关系(例如，整数倍关系)，因此在DTX模式的休眠时段内不存在通信，从而不需要收发上行或者下行数据。DTX模式是根据小小区开关提出的概念，因此在一些例子中，小区在休眠时段内的行为可以与在小小区开关中的定义一致。此外，小区侧可以根据定时器期满前用户设备的待发送数据块的大小来决定是否延长DTX模式的当前周期的激活时段，从而可以在本次发送完毕之后延长DTX模式的激活时段，或者也可能决定不延长(例如没有设置延长的机制)DTX模式的激活时段而在下一个周期进行 发送。
应理解，小区休眠策略通常主要应用在密集部署区域中，因而，在小区侧配置周期性DTX模式的主要目的在于：(1)节省能耗，提高资源利用率。密集部署小区主要是为了满足热点区域的大数据传输服务，然而由于数据业务量的时变特性以及业务分布的非均匀性，在某些时刻密集小区内的用户数量可能会变得很少，同时数据业务需求也很低，此时不需要该小区一直为用户提供服务。因此，为了节省网络能耗，提高资源利用率，可以在某些时刻关闭这些负载量较小的小区；以及(2)协调小区间干扰。在密集部署区域中，由于小区间的地理位置较近，信号衰落较小，因此小区很可能受到来自邻近小区的强烈干扰，致使小区资源利用率降低。因此，为了保证用户设备的服务质量，减少小区间干扰，可以暂时关闭对小区有强烈干扰的相邻小区。此外，替选地，可与邻小区交互关于是否支持DTX模式的信息，如果邻小区是可关闭的(例如，支持DTX模式)，则可配置使得当前小区与目标小区的DTX模式的周期内的激活时段交错开以便避免干扰；或者如果邻小区是不可关闭的(例如，不支持DTX模式)，则可配置使得在来自邻小区的干扰大时当前小区的DTX模式处于休眠时段，而在来自邻小区的干扰小时当前小区的DTX模式处于激活时段。
因此，优选地，装置100还可包括交互单元，该交互单元被配置成使得小区与相邻干扰小区交互各自的周期性非连续发射模式的参数信息，并且小区配置单元可进一步根据所交互的参数信息而使得小区和相邻干扰小区的周期性非连续发射模式的周期内的激活时段彼此间隔开。
优选地，小区配置单元102可根据小区的负载状况和/或小区间的干扰状况而配置小区的周期性非连续发射模式的开始时间点、周期的长度、激活时段的长度和/或休眠时段的长度中的至少一个。
此外，优选地，小区配置单元102可配置使得负载越大，则周期性非连续发射模式的周期越短和/或周期性非连续发射模式的激活时段越长，并且负载越小，则周期性非连续发射模式的周期越长和/或周期性非连续发射模式的激活时段越短。
具体地，在根据小区负载状况进行配置的情况下，小区配置单元102可被配置成计算在预定长度的时间窗内小区的覆盖范围内的资源利用率，如果资源利用率低于预定阈值，则可开启小区的周期性DTX模式以节省功耗，并且还可根据资源利用率来设置周期性DTX模式的周期(即，DTX周期)。优选地，小区配置单元102可将小区的周期性DTX模式的周期配 置为使得一个周期的激活时段(即，ON duration)与休眠时段(即，OFF duration)的比值保持在小区的当前资源利用率附近。应注意，这里所说的小区内的资源利用率是在一个较长时间内进行平均后的结果，因此从较大的时间尺度上来说，负载状况变化不会太大，但是小区会针对当前的具体通信情况进行一些自适应的变化，但总体上来说，小区的DTX模式的一个周期的激活时段与休眠时段的比值可以维持在当前比值附近。然而，如果积累了较长时间的负载变化，小区可以对DTX周期进行调整，并通过系统广播的形式告知其覆盖范围内的用户设备。
此外，在根据小区间干扰状况进行配置的情况下，小区配置单元102还可通过用户设备的测量上报而获取相邻小区的干扰信息，若小区内的大部分用户设备同时报告测量到较高干扰，则开启小区的非周期性DTX模式，并且通过与干扰邻小区进行协调来配置DTX周期。具体地，小区配置单元102可配置使得如果两个小区之间存在较大干扰，则使得这两个小区的DTX周期内的激活时段在时间上隔离开，以减少小区间的干扰，提高系统吞吐量。
应理解，小区配置单元102还可同时考虑到小区负载状况和小区间干扰状况来配置小区的周期性DTX模式，以在节省功耗的同时减少小区间的干扰。
另一方面，如果在预定长度的时间窗内，小区的平均负载状况高于预定阈值或者如果小区内的某些用户设备的业务无法通过周期性DTX模式来实现，则小区配置单元102也可关闭小区的周期性DTX模式，以保持小区的常开状态，从而为用户设备提供所需服务。
此外，已知在用户设备的DRX模式中，空闲状态(例如RRC IDLE状态)的用户设备需要检测特定子帧上的寻呼子帧，以保证自己可以被寻呼到。因此，在现有通信标准的基础上配置DTX模式的激活时段时设置也需要考虑该因素，使得小区在这些寻呼子帧的时隙也保持开启。
用户设备配置单元104可配置成根据周期性非连续发射模式的参数而配置用户设备的周期性非连续接收模式的包括周期的参数，以使得用户设备的周期性非连续接收模式的周期与小区的周期性非连续发射模式的周期兼容。
优选地，用户设备配置单元104可根据小区侧的周期性DTX模式的配置而配置用户设备的周期性DRX模式的相关参数，使得在用户设备的 周期性非连续接收模式处于激活时段时，小区的周期性非连续发射模式也处于激活时段，并且周期性非连续接收模式的周期是周期性非连续发射模式的周期的整数倍以保证兼容。此外，用户设备配置单元104还可配置使得小区内的多个用户设备的DRX配置应尽可能保持对齐(即，各个用户设备的DRX周期的激活时段的开始时间保持一致)以方便调度。
优选地，用户设备配置单元104可配置周期性非连续接收模式的开始时间点、周期的长度、激活时段的长度和/或休眠时段的长度中的至少一个。此外，优选地，与小区侧的周期性DTX模式的配置类似，用户设备配置单元104可配置使得周期性非连续发射模式的周期越短，则周期性非连续接收模式的周期越短，并且周期性非连续发射模式的周期越长，则周期性非连续接收模式的周期越长。
应理解，周期性DRX模式的周期与周期性DTX模式的周期的相关性比较明显，但周期性DRX模式的周期内的激活时段与周期性DTX模式的周期内的激活时段不一定有直接的联系，这是由于周期性DTX模式的周期内的激活时段还与该小区所支持的用户设备分组数目有关系，分组数目越多，那么每组用户设备被分配到的激活时段也会相应变短。
从以上描述可以看出，通过由小区配置单元102对小区的周期性DTX模式进行配置以及由用户设备配置单元104对用户设备的周期性DRX模式进行配置，实现了小区侧的周期性非连续发射模式与用户设备侧的周期性非连续接收模式之间的协调，以在保证用户设备的服务质量的同时尽可能降低系统功耗。
然而，考虑如下情景：如果小区内的所有用户设备同时从休眠状态进入激活状态，则会导致某些用户设备不能被立即调度。为了解决该问题，本公开了提出了如下解决方案。以下将参照图2详细描述该解决方案。
图2是示出根据本公开的另一实施例的无线通信系统中的装置的功能配置示例的框图。
如图2所示，根据本实施例的无线通信系统中的装置200可包括小区配置单元202、用户设备配置单元204、分组单元206和分配单元208。其中，小区配置单元202和用户设备配置单元204的功能配置与以上参照图1描述的小区配置单元102和用户设备配置单元104的功能配置相同，在此不再赘述。以下将仅详细描述分组单元206和分配单元208的功能配置示例。
分组单元206可被配置成对用户设备进行分组，使得同一组内的用户设备的周期性非连续接收模式的周期保持对齐并且不同组的用户设备的周期性非连续接收模式的激活时段彼此偏移。将用户设备划分成不同的DTX/DRX分组的目的主要在于从时间上进行资源分配调度。
参照图3，图3是示出周期性DTX模式的配置和周期性DRX模式的示例性配置的示意图。如图3所示，在该示例中，用户设备被划分成DTX/DRX组1和DTX/DRX组2，其中每组用户设备的激活时段彼此偏移。
分配单元208可被配置成根据用户设备的分组对小区的周期性非连续发射模式的一个周期内的激活时段进行分配，使得针对不同组的用户设备分配不同的激活时段。
优选地，分配单元208可配置使得如果小区的周期性非连续发射模式的一个周期内仅存在一个激活时段，则针对不同组的用户设备设置不同的激活时段偏移，以及如果小区的周期性非连续发射模式的一个周期内存在多个激活时段，则为不同组的用户设备分配多个激活时段中的不同激活时段。通常，小区只在相应的激活时段调度该激活时段对应的分组内的用户设备在该激活时段内接收下行信号，以便均衡各个时段内的业务量。
此外，优选地，用户设备配置单元204可根据针对用户设备分配的激活时段而配置使得用户设备的周期性非连续接收模式的一个周期内的激活时段与针对该用户设备分配的激活时段匹配。
如图3所示，DTX/DRX组1的DRX周期的激活时段对应于DTX周期中的激活时段的竖线阴影部分，并且DTX/DRX组2的DRX周期的激活时段对应于DTX周期中的激活时段的斜线阴影部分。
此外，优选地，分配单元208可进一步配置使得在开启了小区的周期性非连续发射模式之后，如果用户设备到来了实时性强和/或数据传输量大的业务并且当前配置的周期性非连续发射模式无法满足用户设备当前的业务需求，则将小区的周期性非连续发射模式的一个周期内的用于一组或多组用户设备的激活时段分配给该用户设备以为用户设备服务。例如，如图3所示，如果第一组中的某个用户设备到来了实时性强和/或数据传输量大的业务，则可将分配给第二组用户设备的DTX周期内的激活时段也分配给该用户设备以应对突发状况。例如，小区侧在第一组用户设备的DRX周期的激活时段内对第一用户设备进行调度，以使得第一组用户设 备在超出其DRX周期的激活时段的时段内(例如，在分配给第二组用户设备的激活时段内)接收下行信号。也就是说，在满足特定条件下，小区侧在分配给第二组用户设备的激活时段内也与第一组用户设备进行通信。
这里，应指出，尽管在本实施例中由小区侧对用户设备进行分组并且将分组结果通知给用户设备，但是分组也可以是随机的，例如，用户设备可以基于其自身的国际移动用户识别码(IMSI)而按照预定规则进行分组。在该情况下，可以不需要分组单元206。
此外，还考虑如下场景：如果某个用户短时突发业务数据量较大，因此可能在单个DTX周期内无法完全发送数据。针对该问题，本公开还提出了以下解决方案。以下将参照图4详细描述该解决方案。
图4是示出根据本公开的另一实施例的无线通信系统中的装置的功能配置示例的框图。
如图4所示，根据本实施例的无线通信系统中的装置400可包括小区配置单元402、用户设备配置单元404和子周期非连续发射模式配置单元406。其中，小区配置单元402和用户设备配置单元404的功能配置与以上参照图1描述的小区配置单元102和用户设备配置单元104的功能配置相同，在此不再赘述。以下将仅详细描述子周期非连续发射模式配置单元406的功能配置示例。
子周期性非连续发射模式配置单元406可配置成如果在周期性非连续发射模式的一个周期内的激活时段中无法满足用户设备的通信需求，则在小区配置子周期性非连续发射模式，并且使得用户设备的子周期性非连续接收模式的周期与子周期性非连续发射模式的周期对齐。
具体地，在某些用户设备到来了短时突发数据量较大的业务以致在单个DTX周期的激活时段内无法完全发送的情况下，由于此时小区内的负载状况并不重从而没有必要仅由于这些用户设备而关闭周期性DTX模式，因此可针对这些用户设备配置子周期性DTX模式，即，在小区的周期性DTX模式的周期内的原休眠时段内设置一个或多个激活时段，使得小区在这一个或多个激活时段内开启以专门为这些用户设备提供服务。相应地，在用户设备侧配置了子周期性DRX模式，并且使得该子周期性DRX模式的激活时段与子周期性DTX模式的激活时段对齐。在图3中示出了子周期性DTX模式的配置，如子DTX/DRX组所示。
应理解，DRX周期是DTX周期的整数倍，DRX周期同时也是子 DRX周期的整数倍，在图3所示的示例中DRX周期是DTX周期的1倍，DRX周期是子DRX周期的2倍，本领域技术人员可以根据此示意图设计出其他的具体可行的方案。
根据以上参照图2描述的DTX/DRX分组设置和参照图4描述的子周期性DTX模式设置，可以对小区的一个DTX周期内的激活时段进行分配，以在保证所有用户设备正常通信的同时尽量降低功耗。
假设在配置了小区侧的周期性DTX模式和用户设备侧的周期性DRX模式之后，如果某个用户设备到来了实时性较强的业务，如VOIP(网络电话)业务，并且相邻的数据包之间的时间跨度小于DTX的周期，此时可首先尝试使用多个DTX/DRX组为该用户设备服务，或为该用户设备专门配置一个子周期性DTX。如果小区仍然无法很好支持小区内部分特殊用户的业务传输，则该小区也可以尝试将自己的DTX周期缩短并通知用户设备改变其DRX配置，或者退出周期性DTX模式以为该类用户进行服务。应理解，缩短前的DTX周期应该是缩短后的DTX周期的整数倍。
此外，对于某些数据传输量很大的业务，如视频下载业务，在一个DTX周期的激活时段期间无法完成上一个DTX周期内到来的数据的传送，那么可以延长DTX周期的激活时段，或者也可以通过上述方法实现。
图5是示出根据本公开的另一实施例的无线通信系统中的装置的功能配置示例的框图。
如图5所示，根据本实施例的无线通信系统中的装置500可包括小区配置单元502、用户设备配置单元504和服务单元506。其中，小区配置单元502和用户设备配置单元504的功能配置与参照图1描述的小区配置单元102和用户设备配置单元104的功能配置相同，在此不再赘述。以下将仅详细描述服务单元506的功能配置示例。
服务单元506可配置成如果小区无法支持用户设备的业务，则使得小区将该业务卸载给没有开启周期性非连续发射模式的小区，或者对于能够支持载波聚合和/或双连接场景的用户设备，则利用不同小区的周期性非连续发射模式的周期内的激活时段为该用户设备服务。
具体地，例如，如果小区的周期性DTX机制无法支持用户设备的大量数据传输，则小区可以将该用户设备的业务卸载给其它没有开启周期性DTX机制的小区，例如，宏小区。此外，如果该用户设备是支持载波聚 合(CA-capable)和/或双连接场景(dual-connectivity-capable)的用户设备，并且邻小区也开启了周期性DTX模式且彼此之间的激活时段基本上不重叠，那么可以进行小区间的协同传输。
小区间的协同传输主要针对相邻小区都处于周期性DTX模式且用户设备支持CA-capable或者dual-connectivity-capable场景的情况。在该情况下，如果用户设备有时延敏感性业务或者短时大数据量业务需要传送，那么可以分别利用不同的小区的DTX周期内的激活时段进行数据通信以为该用户设备服务，如图3的底部所示。
在该情况下，优选地，装置500还可包括交互单元，从而经由交互单元得到邻小区的周期性DTX模式的相关参数，从而可以根据该参数设置本小区的激活时段，使得本小区的激活时段与邻小区的激活时段形成没有空隙的交错(或交叠)，这样一旦本小区进入休眠，其服务的用户设备马上可以转移由邻小区服务。
在本公开的实施例中，小区主要指的是小小区，包括例如微小区(micro cell)、毫微微小区(femto cell)等等。这是由于本公开中的DTX/DRX方案通常是针对小小区密集部署的区域而进行的。
应指出，以上参照图1至图5描述的装置可以是小区内的基站，或者可布置在小区内的基站中或者也可独立于基站而布置，本公开对此不作限制。

应指出，装置600可以是用户设备，或者可布置在用户设备内或者也可独立于用户设备而布置，本公开对此不作限制。
应理解，尽管以上参照图1至图6描述了根据本公开的实施例的无线通信系统中的装置的功能配置示例，但这仅是示例而非限制，并且本领域技术人员可以根据本公开的原理对上述单元进行添加、删除和/或组合，并且这样的变型均认为落入本公开的实质范围内。

如图8所示，根据本实施例的方法800可包括接收步骤S802和配置步骤S804。
在接收步骤S802中，可从小区接收周期性非连续接收模式的配置信 令。
在配置步骤S804中，可根据配置信令而配置用户设备的周期性非连续接收模式，使得用户设备的周期性非连续接收模式的周期与小区的周期性非连续发射模式的周期兼容。
应理解，尽管以上参照图7和图8描述了根据本公开的实施例的无线通信系统中的方法的过程示例，但是应理解，这仅是优选示例而非限制，并且本领域技术人员可根据本公开的原理、结合实际需要对上述过程进行修改、组合、子组合和变更，并且这样的变型认为落入本公开的范围内。
此外，应指出，参照图7和图8描述的方法实施例分别与以上参照图1至图5描述的装置100至装置500以及参照图6描述的装置600的实施例相对应，因此对于在方法实施例中未详细描述的内容，可参见以上装置实施例中相应位置的描述，在此不再重复描述。
图9是示出根据本公开的实施例的无线通信系统中的装置的功能配置示例的框图。
如图9所示，根据本实施例的无线通信系统中的装置900可包括小区配置单元902，该小区配置单元902可被配置成根据小区的负载状况和/或小区间的干扰状况而控制小区的周期性非连续发射模式并且配置周期性非连续发射模式的包括周期的参数。
优选地，如图9所示，小区配置单元902可进一步包括判断模块9021和参数配置模块9022。
判断模块9021可被配置成基于小区的负载状况和/或小区间的干扰状况判断是否开启小区的周期性非连续发射模式。优选地，当小区的负载状况小于第一预定阈值和/或小区间的干扰状况大于第二预定阈值时，判断模块9021判断开启小区的周期性非连续发射模式。
参数配置模块9022可被配置成响应于所述判断模块判断开启小区的周期性非连续发射模式，基于小区的负载状况和/或小区间的干扰状况配置周期性非连续发射模式的参数，该参数包括周期、每个周期的激活时段和休眠时段，以使得小区在休眠时段不为用户设备提供数据传输服务。
与图9所示的装置相对应地，图10是示出根据本公开的实施例的无线通信系统中的方法的过程示例的流程图。
如图10所示，根据本实施例的无线通信系统中的方法1000可包括小 区配置步骤S1002，在小区配置步骤S1002中，可根据小区的负载状况和/或小区间的干扰状况而控制小区的周期性非连续发射模式并且配置周期性非连续发射模式的包括周期的参数。
优选地，如图10所示，小区配置步骤S1002可进一步包括判断步骤S1002-1和参数配置步骤S1002-2。
在判断步骤S1002-1中，可基于小区的负载状况和/或小区间的干扰状况判断是否开启小区的周期性非连续发射模式。优选地，当小区的负载状况小于第一预定阈值和/或小区间的干扰状况大于第二预定阈值时，判断开启小区的周期性非连续发射模式。
在参数配置步骤S1002-2中，可响应于所述判断模块判断开启小区的周期性非连续发射模式，基于小区的负载状况和/或小区间的干扰状况配置周期性非连续发射模式的参数，该参数包括周期、每个周期的激活时段和休眠时段，以使得小区在休眠时段不为用户设备提供数据传输服务。
可以看出，通过根据小区的负载状况和/或小区间的干扰状况而开启和关闭小区的周期性DTX模式并对诸如DTX模式的周期、激活时段和休眠时段等参数进行配置，与现有技术中小区侧通常保持常开状态相比，可以降低功耗并且可以减小干扰。

相应地，用于承载上述包括机器可执行的指令的程序产品的存储介质也包括在本发明的公开中。该存储介质包括但不限于软盘、光盘、磁光盘、存储卡、存储棒等等。
另外，还应该指出的是，上述系列处理和装置也可以通过软件和/或固件实现。在通过软件和/或固件实现的情况下，从存储介质或网络向具有专用硬件结构的计算机，例如图11所示的通用个人计算机1100安装构成该软件的程序，该计算机在安装有各种程序时，能够执行各种功能等等。
在图11中，中央处理单元(CPU)1101根据只读存储器(ROM)1102中存储的程序或从存储部分1108加载到随机存取存储器(RAM)1103的程序执行各种处理。在RAM 1103中，也根据需要存储当CPU 1101执行各种处理等等时所需的数据。
CPU 1101、ROM 1102和RAM 1103经由总线1104彼此连接。输入/输出接口1105也连接到总线1104。

应用示例1
在LTE子帧的0号以及5号时隙，需要固定发送PSS/SSS同步信号，因此，在本公开的DTX方案中，需要考虑这些时隙上同步信号的发送，换言之，在当前LTE系统中应用DTX时，这些时隙应当设置位于DTX的激活时段内。
已知小小区开关根据其操作周期的尺度不同而被划分为子帧级别、半静态以及休眠态这三种。在当前LTE技术中，实现子帧级别的动态调度比较困难，而对于休眠态，则又因为时间尺度太大的问题，主要在RAN3中进行讨论。因此，在RAN1/2的讨论中，主要集中在半静态的解决方案，而本公开的周期性DTX方案的颗粒度也是与半静态调度中的方案类似，在几百毫秒到几秒的数量级之间。
随着LTE标准化的演进，对于小小区的支持也会越来越好，因此同步信号以及小小区发现信号未来可能会发生改变，这些潜在的变化都会更有利于实现本公开中的周期性DTX机制，例如不固定于0号以及5号时隙发送同步信号，而使得DTX设置的灵活性更高。
应用示例2
LTE-U是目前3GPP的热点话题之一，而本公开也可以针对LTE-U的部署场景进行一些优化。由于LTE-U是非授权频段，因此存在很多不确定的频谱干扰。在LTE-U的场景下，为使用非授权频段频谱资源的小区配置DTX以降低对授权用户的干扰。在小区与用户设备已经确定好DTX/DRX周期之后，由于存在某些用户设备的需求无法满足的情况，因此需要额外为这些用户设备分配资源。其实现方式可以包括：通过计时器延长激活时段的时间；配置子周期性DTX；以及与邻小区进行协调。在LTE-U中，在选择这些备选方案时，需要考虑到LTE-U空口上的干扰情况，从而小区会根据不同备选方案的干扰情况选择最优方案。
以上参照附图描述了本公开的优选实施例，但是本公开当然不限于以 上示例。本领域技术人员可在所附权利要求的范围内得到各种变更和修改，并且应理解这些变更和修改自然将落入本公开的技术范围内。

在该说明书中，流程图中所描述的步骤不仅包括以所述顺序按时间序列执行的处理，而且包括并行地或单独地而不是必须按时间序列执行的处理。此外，甚至在按时间序列处理的步骤中，无需说，也可以适当地改变该顺序。
