现在参考所图示的示例性实施例，并且特定的语言在此将被用于描述相同的实施例。然而，将被理解的是：不由此意图限制本发明的范围。
具体实施方式

定义
如在此所使用的，术语“基本上”指代动作、特性、性质、状态、结构、项目、或结果的完全或接近完全的范围或程度。例如，被“基本上”包含的对象将意味着所述对象被完全地包含或接近完全地包含。在一些情形下，从绝对完全性偏离的精确可允许程度取决于特定的背景。然而，通常来讲，完成的接近将使得具有相同的总体结果，好像获得绝对和整体的完成。当被用于否定含义时，“基本上”的使用同样可适用于指代动作、特性、性质、状态、结构、项目、或结果的完全或接近完全的缺乏。
示例性实施例
下面提供技术实施例的初始概述，并且然后特定的技术实施例稍后被进一步详细地描述。这个初始的概要旨在帮助读者更快地理解技术，而不是意图等同所述技术的关键特征或必要特征，也不意图限制要求保护的主题的范围。为了下面所描述的概述和实施例的清楚，接下来的定义被提供。
许多类型的无线设备可以在每个无线设备中包括多个无线电装置。例如，无线设备可以装备有相对高功率的WWAN收发器，诸如，配置成基于蜂窝类型标准(诸如，第三代合作伙伴计划(3GPP)长期演进(LTE)标准)操作的收发器、或另一种类型的WWAN收发器，以及相对低功率的收发器，诸如，WLAN收发器、蓝牙收发器、和/或GNSS接收器。WLAN收发器、蓝牙收发器和GNSS接收器被统称为低功率收发器，因为它们典型地在比由WWAN收发器使用的功率级别显著低的功率级别进行操作(即，发射和接收)。许多类型的低功率收发器在工业、科学和医疗(ISM)频带中操作，并且因此被称为ISM收发器。可以意识到的是：其他类型的低功率收发器(针对相对短的距离(诸如，小于100米) 上通信而加以配置)也可以被包括在多无线电装置的设备中。一个挑战是：确定如何避免并置(collocated)的收发器和接收器之间的干扰。并置的收发器和/或接收器之间的干扰在此被称为共存干扰。
为了减小共存干扰，存在数个类型的潜在解决方案。一个潜在解决方案是使用频分复用(FDM)来移动来自一个收发器的信号，使其在频率上进一步远离另一个收发器的信号，从而产生更多的频率分离。另一个潜在解决方案是使用时分复用(TDM)，其中调度可以被使用，使得当一个收发器正在发射时，另一个共位收发器不同时接收。射频解决方案涉及：使用可以被用于减少带外(OOB)发射量的射频滤波、使用发射器处的滤波器、或使用接收器处的滤波器来阻止入局的带外信号。基于功率的解决方案可以被用于减少发射功率，从而潜在降低干扰级别。通过组合两个或更多之前给出的解决方案，混合解决方案也是可能的。
在无线广域网(诸如，2008年第四季度的第三代合作伙伴计划(3GPP)长期演进(LTE)网络版本8)中，非连续接收(DRX)的概念被引入，以用于节约功率。DRX可以被用于使无线设备(诸如，3GPP LTE网络中的用户设备(UE))能够非连续监控控制信道，诸如，被从发射站(诸如，增强节点B(NodeB)(eNodeB))传送的物理下行链路控制信道(PDCCH)。因为UE处的接收器可以被关闭，所以非连续监控可以在UE处提供显著的功率节约。使用DRX的3GPPLTE收发器的调度将被在下面更全面的解释。
除了节约功率之外，DRX还可以被用于提供TDM解决方案，以用于减少共位设备的共存干扰。例如，在并置的3GPP LTE配置的收发器(LTE)和低功率收发器(诸如，蓝牙配置的收发器(BT))之间的共存干扰可以被通过在所述LTE收发器不接收时调度所述 BT收发器来发射并使用DRX减小。在一个实施例中，LTE收发器可以被配置成通过减小监控控制信道(诸如，物理下行链路控制信道(PDCCH))的时间量而更经常地关闭。另一个 TDM解决方案是LTE拒绝，其可以被用于处理短期工业、科学和医疗(ISM)的无线电事件。短期ISM事件是持续相对短的时段(诸如，在长度上从近似0.5毫秒(ms)到数十毫秒)的多无线电装置的设备中的ISM或低功率收发器进行的通信。在这个解决方案中，由于可能在ISM侧发生的一些关键的短期事件，无线设备(诸如，UE)可以自主拒绝由 eNodeB分配的LTE资源。例如，短期事件可以涉及可能在BT/Wi-Fi连接建立或其他重要信令期间发生的一个或多个事件。另外，如果这些事件未被在来自LTE收发器的传输上区分优先级，则连接建立的大延迟或失败可能发生。LTE拒绝的解决方案假设被用于不经常发生的事件。LTE拒绝具有如下问题：因为eNB不能够区分LTE拒绝和UE的PDCCH解码错误，所以它可能影响PDCCH和物理上行链路信道(PUSCH)的链路适应。LTE拒绝的另一个缺点是：所分配的上行链路资源可能被浪费。
依据本发明的一个实施例，短时DRX配置可以被用于处理短期ISM事件。短时 DRX配置可以消除对链路适应的影响。此外，所分配的上行链路的潜在资源浪费可以被相对于LTE拒绝的使用而显著地减小。在另一个实施例中，布尔值运算符(在此被称为过程活跃指示符)可以被包括在DRX配置中，以禁止LTE收发器处的PDCCH的监控。这能够增加并置的低功率收发器能够操作的时间。实施例和附加的优点将在下面更全面地讨论。
非连续接收
非连续接收(DRX)是无线通信中所使用的过程，用于通过相对于较高的功率收发器(诸如，WWAN收发器)提供并置的收发器或接收器进行操作的已知时间，来减小无线设备上的功率使用并减少共存干扰。无线设备中的WWAN收发器可以与发射站(被称为网络节点)进行通信，以协商无线设备将从网络节点接收通信的时间段。在信息未被接收的所协商的时间期间，无线设备可以把其接收器关闭，并进入低功率的状态。非连续接收被用于多个不同的无线通信标准，包括(但不限于)3GPP LTE版本8、9和10，以及电气和电子工程师协会(IEEE)的802.11标准。
在3GPP LTE(LTE)标准中，一组功能被提供以使UE中的LTE配置的接收器能够执行休眠事件。这些休眠事件可以持续大约单个毫秒到数百毫秒或更长的时间。休眠事件的持续时间和计时可以在UE和网络节点之间协商。所述协商可以使用高级别的信令(诸如，开放系统互联(OSI)级别3通信或其他类型的高级别信令)来执行。3GPP LTE标准中的 OSI级别3通信的一个示例是无线电资源控制(RRC)信令。在LTE标准中，RRC信令被用于控制UE中LTE配置的收发器处的DRX操作。
3GPP LTE标准的帧结构的简要描述在此作为参考被提供。图1图示了下行链路无线电帧结构类型2。在示例中，用于传送数据的信号的无线电帧100可以被配置成具有10毫秒(ms)的持续时间Tf。每个无线电帧可以被分割或划分成10个子帧110i，其均为1ms 长。每个子帧可以被进一步再分成两个时隙120a和120b，每一个具有0.5ms的持续时间 Ts/ot。由发射站和接收站使用的分量载波(CC)的每个时隙可以包括基于CC频率带宽的多个资源块(RB)130a、130b、130i、130m和130n。CC可以具有载波频率，所述载波频率具有带宽和中心频率。每个RB(物理RB或PRB)130i可以包括：每个载波12-15kHz的子帧136(在频率轴上)和6或7个正交频分复用(OFDM)符号132(在时间轴上)。如果短的或正常的循环前缀被使用，则RB可以使用7个OFDM符号。如果扩展的循环前缀被使用，则RB可以使用6个OFDM符号。所述资源块可以被使用短的或正常的循环前缀映射到84个资源元素(RE)140i，或所述资源模块可以被使用扩展的循环前缀映射到72个 RE(未示出)。RE可以是一个OFDM符号142乘以一个子载波(即，15kHz)146的单元。在正交相移键控(QPSK)调制的情形下，每个RE可以传送两位150a和150b的信息。其他类型的调制可以被使用，诸如，在每个RE中传送较大位数的16正交振幅调制(QAM) 或64QAM，或者在每个RE中传送较少位数(单个位)的二进制相移键控(BPSK)调制。 RB可以被针对从eNodeB到UE的下行链路传输配置，或者RB可以被针对从UE到 eNodeB的上行链路传输配置。
3GPP LTE标准中的网络节点是UE采用其已建立至少一个分量载波的节点。网络节点可以是完全的功率eNodeB，其被称为宏节点。可替代地，UE可以与低功率节点(诸如，毫微微节点、微微节点、或家庭eNodeB(HeNB))通信。UE还可以经由中继节点与宏节点或低功率节点通信。
UE可以在RRC_IDLE(RRC_空闲的)或RRC_CONNECTED(RRC_连接的)状态下被设置以延长电池的寿命，而仍然保证高的服务质量(QoS)和连接速度。3GPP LTE实现方式允许UE减少为了控制信道信息而监控控制信道(诸如，PDCCH)所花费的时间量。取代在每个传输时间间隔(TTI)监控PDCCH，UE可以仅在通过RRC通信设置的特定时间间隔期间监控PDCCH。活跃时间是与DRX操作相关的时间，在该时间期间UE监控 PDCCH子帧中的PDCCH。因为所有的调度控制信息在PDCCH上被传送，所以这个解决方案可以在下行链路和上行链路二者中提供好处。在非活跃状态期间，UE可以配置成进入功率节约状态，其可以显著降低UE处的LTE配置的射频调制解调器的功率消耗，从而降低 UE处并置的无线电装置处的干扰。
RRC可以被用于通过设置各种参数来管理DRX的使用。可以在RRC_CONNECTED 状态下被设置的参数的示例在接下来的表格中被图示。
当网络为UE配置DRX时，为DRX非活跃定时器定义值，该DRX非活跃定时器在 3GPPLTE技术规范(TS)36.321中被称为在每个数据块已被发送之后开始运行的drx-非活跃定时器。如果新的数据被发送，则所述定时器重新起动。如果当所述定时器期满时仍无数据被发送，则该设备可以进入具有短DRX周期的DRX模式。这意味着UE将基于短DRX 周期以相对短的模式有效地休眠(sleep)和唤醒。如果新的数据被接收，则其可以被相对快速地接收，因为UE仅休眠短的时段。短DRX周期模式还可以附着可配置的短DRX周期定时器(即，drxShortCycleTimer)。一旦这个定时器期满(即，在短周期模式期间无数据被接收)，UE可以进入长DRX周期。长DRX周期可以进一步减少功率的使用，但也增加了等待(latency)时间。
在非活跃时段期间，UE可以仅检查控制信道并且资源可被分配。在每个DRX周期(短和长)中，RF调制解调器可以被开启长达由持续期定时器设置的多个连续子帧之久，以侦听控制信道。当数据活跃在下行链路或上行链路中被检测到时，eNodeB触发UE的短 DRX周期，从而增加UE的响应度和连接性。长DRX周期和短DRC周期之间的过渡可以由eNodeB直接触发或由定时器确定。
非活跃定时器可以指定TTI的连续数量，在此期间UE将在成功解码指示UE的上行链路或下行链路数据传递的PDCCH之后监控PDCCH。在数据传递期间，非活跃定时器可以在某个时段保持UE唤醒，即使持续期定时器已期满也如此。在下行链路中，非活跃定时器通常在持续期时段内被触发。如果持续期时段更长，则非活跃定时器可以在唤醒时段内起动和期满。在这个示例中，非活跃定时器将不对终端的平均唤醒时间产生贡献。非活跃定时器仅可以在上行链路和下行链路二者中针对新的传送触发，而不针对重传触发。
图2a图示了DRX参数的一个示例。在这个示例中，短DRX周期在持续期的开端部分开始，并且在下一个持续期的开端部分结束。非活跃定时器被示为与在前面的段落中所讨论的的持续期重叠。
另一个DRX特征与HARQ重传期间的功率节约相关。例如，当UE无法解码HARQ 活跃过程的传输块时，UE假设下一个重传将在DRX重传定时器之后发生。这允许UE进入功率节约状态而无需侦听PDCCH。
在3GPP LTE规范中，HARQ往返时延(RTT)定时器可以在指示下行链路共享信道(PDSCH)传输的PDCCH的1ms(用于解码延迟)之后起动。HARQ RTT定时器可以针对每个下行链路共享信道传输而起动。
图2b图示了长DRX周期的示例。在这个示例中，长DRX周期被相对于持续期定时器、重叠的非活跃定时器、HARQ RTT定时器和重传定时器示出。HARQ RTT定时器在 PDCCH的解码延迟之后起动。
图3图示示出了短时DRX配置建立以针对短期ISM事件支持设备内共存的框图。ISM事件(如在此所使用的)是来自并置的收发器的通信，所述收发器在ISM频带中传送(即，发射和/或接收)。术语短时DRX配置指临时DRX配置。之前，DRX配置被认为是可适用的，直到新的配置被接收。在短时DRX配置中，DRX配置对于一个或多个DRX周期是有效的。其中配置为有效的长度可以使用高级别的信令(诸如，无线电资源控制 (RRC)信令)传送。一旦配置长度已过去，DRX配置可以自动地释放。
如图3中所示的，在短期ISM事件发生之前，无线设备(诸如，UE)可以把“辅助信息”发送到eNodeB。这种信息可以包括：
时分复用(TDM)模式的周期；
调度时段(或非调度时段)；以及
可适用的TDM解决方案的持续时间。
然后，eNodeB可以为LTE调制解调器配置DRX参数，包括周期和调度时段。周期可以是TDM模式的周期。所述周期可以相对于多个子帧设置，诸如，SF10指10个子帧，sf20指20个子帧，以此类推。调度时段可以是LTE发射/接收发生的持续时间。这个调度时段被称为LTE调度时段，并且可以被以子帧为单位分配或测量。
当短期ISM时间结束时，UE可以再次把辅助信息发送到eNodeB(如图3中所示的)。然后，eNodeB可以把重新配置消息发送到UE。然而，这些消息典型地是不需要的。通过消除这些消息，大量的控制信令开销可以被节约。
依据本发明的一个实施例，取代在ISM事件已发生之后发送辅助信息和重新配置消息，称为“DRX有效持续时间”的时间段可以被用于识别DRX应保持有效多久(如图4a 中所图示的)。
在图4a的实施例中，辅助信息(诸如，DRX-辅助数据-r11(DRX-AssistantData-r11)可以被从UE传送到eNodeB。图4b图示DRX-辅助数据-r11字段描述的一个示例。然后，eNodeB可以传送短时DRX配置信息，诸如，扩展DRX-配置-r11(ExtendedDRX- Congif-r11)信息。
在接收UE的辅助信息之后，eNodeB可以针对所选择的持续时间配置DRX。这种所选择的持续时间可以被指示为DRX周期的数量。在一个实施例中，所选择的持续时间可以是长DRX周期的设置数量。然而，不同的时间段也可以被使用，诸如，短DRX周期或其他可识别时间段。在DRX的选择持续时间之后，DRX配置可以被自动释放(如先前所讨论的)。所选择的持续时间的长度可以取决于所述短期ISM事件的特性。
使用针对短期ISM事件的DRX有效持续时间的一个显著优点是：与LTE拒绝的解决方案相比较，不存在链路适应和上行链路资源浪费的问题。当与3GPP LTE版本10的规范中所记载的DRX解决方案相比较时，使用针对短期ISM事件的DRX有效持续时间提供了控制信令开销的显著节约。DRX有效持续时间去掉了在短期ISM事件发生之后传送附加的辅助信息和重新配置信息的需求(如图3中所示的)。
图4b中图示了针对UE辅助信息的抽象语法标记一(ASN.1)代码的一个示例。LTE调制解调器的周期和调度时段二者可以被基于整数的子帧选择。DRX有效持续时间可以被选择为整数的DRX周期。在这示例中，所述整数在1个到8个DRX周期之间被选择。然而，这不旨在是限制性的。DRX有效持续时间可以比8个DRX周期大，这取决于使用的系统类型。所选择的整数值可以被选择以允许DRX周期持续长达比所述短期ISM事件长的时间长度之久。
图4d中图示了针对eNodeB的配置的ASN.1代码的示例。3GPP LTE版本10规范中的DRX-配置信息元素(IE)不能被扩展。因此，有效持续时间可以在DRX-配置IE的扩展中被实现。在这个示例中，持续期定时器(onDurationTimer)可以被选择具有从单个子帧至高达200个子帧的值。相似地，DRX非活跃定时器(DRX-InactivityTimer)允许从一个子帧到2560个子帧的选择，具有9个备用位置以允许其他选择。DRX重传定时器(DRX- Retransmissiontimer)可以从1个子帧到33个子帧中选择。长DRX-周期开始偏移 (longDRX-CycleStartOffset)允许在长DRX周期中选择偏移，所述偏移大约从第一(即， 0)子帧到高达子帧2559。短DRX周期(ShortDRX-Cycle)可以被选择具有从2个子帧到高达640个子帧的长度。DRX短周期定时器(DRXShortCycleTimer)可以被选择为所述短 DRX周期的整数。附加字段有效持续时间在图4d中被图示为加下划线。有效持续时间的描述与其相对于图4b的描述(如在先前的段落中所描述的)相同。因此，在这个示例中，有效持续时间可以是TDM模式周期的整数倍，其被以子帧测量。
如先前所讨论的，DRX还可以被用于提供TDM解决方案，用以减少共位LTE和并置的低功率收发器的共存干扰。在一个实施例中，附加的布尔值运算符(被称为“过程活跃指示符(processActivelndicator)”)可以被包含在DRX配置信息中。
当过程活跃指示符被设置为真时，则DRX操作可以如先前在3GPP LTE版本10的规范中所定义的那样继续。然而，当过程活跃指示符被设置为假时，则多无线电装置的设备中的LTE收发器可以被配置，使得PDDCH子帧将不被针对潜在的重传监控。
例如，图5示出了从eNodeB到UE的LTE传输中的多个子帧的框图。在这个示例中，存在三个帧，被标记为m、m+1、m+2。在这个示例中，DRX被配置，使得这是其中 LTE可以发射和接收的调度时段。在子帧3中，PDCCH被从eNodeB在下行链路中接收。在帧m+1和m+2中，LTE收发器典型地被配置成基于在3GPP LTE版本10的规范中所定义的DRX来针对潜在重传监控PDCCH子帧。然而，eNodeB可以把过程活跃指示符设置为假。当这个设置在UE处被接收时，UE可以被配置，使得其不再在非调度时段期间针对挂起的上行链路重传而监控PDCCH，从而降低功率的使用，并增加在来自LTE收发器的干扰很少或者没有的情况下多无线电装置的设备中并置的无线电装置用于通信的时间量。
在TDD的LTE中存在7个不同的上行链路/下行链路(UL/DL)配置。每个配置在每个帧中提供不同数量的上行链路(U)子帧、下行链路(D)子帧和特殊(S)子帧。所述特殊子帧可以包括下行链路导频时隙、防护时段、和上行链路导频时隙。针对LTE的 UL/DL配置在接下来的表格中被图示。
过程活跃指示符可以在每个UL/DL TDD配置中以及在频分双工(FDD)中被使用，以禁止在非调度时段针对挂起的上行链路重传监控PDCCH。
可以对3GPP LTE版本10作出下列改变，以把增进引入3GPP规范。对于3GPP技术规范(TS)36.331V.10.4.0(2011-12)，可以引入被称为过程活跃指示符的布尔值运算符。当布尔值运算符为真时，LTE收发器可以在调度时段期间监控PDCCH，并可以在非调度时段期间针对挂起的上行链路重传来监控。
当布尔值运算符过程活跃指示符被设置为假时，则UE可以被配置，使得其不在非调度时段期间针对挂起的上行链路重传而监控PDCCH(如先前所讨论的)。
在一个实施例中，过程活跃指示符可以被添加为DRX-配置的扩展。一个包括过程活跃指示符的DRX-配置的示例在图6中被图示。对DRX-配置的改变以下划线来强调，示出了布尔值运算符。DRX-配置可以是3GPP TS 36.331V.10.4.0(2011-12)中所定义的MAC主配置信息元素的一部分，并且可以被用于为信令和数据无线电承载指定MAC主配置。
对于3GPP TS 36.321V.10.4.0(2011-12)第5.7节，接下来的添加可以被做出，所述改变以下划线来强调：
·当DRX周期被配置时，活跃时间包括下述项发生时的时间：
ο持续期定时器或drx-非活跃定时器或drx-重传定时器或mac-争用解决方案定时器 (如在3GPP TS 36.321分则5.1.5中所描述的)正在运行；或
ο调度请求在PUCCH上被发送并且是挂起的(如在3GPP TS 36.321分则5.4.4中所描述的)；或
ο针对挂起HARQ重传的上行链路许可能够发生，扩展DRX-配置-r11中的过程活跃 指示符为真，且在对应的HARQ缓冲器中存在数据；或
ο在针对前同步码的随机存取响应的成功接收未被UE选择之后，指示寻址到UE的C-RNTI的新传输的PDCCH未被接收(如在3GPP TS 36.321分则5.1.4中所描述的)。
对3GPP LTE规范的这些附加可以使DRX能够在通信系统中被使用，所述通信系统被配置成基于3GPP LTE规范进行操作。通过配置UE使得其不在非调度时段期间针对挂起的上行链路重传监控PDCCH，其显著增加了多无线电装置的设备中的低功率收发器能够通信的时间量，从而减少共存干扰的量。
在一个实施例中，当UE传达：有共存干扰出现时，eNodeB可以传达：过程活跃指示符为假。
在一个实施例中，公开了在多无线电装置的无线设备中减小共存干扰的方法700(如图7中所示的)。所述方法包括确定共存干扰正在多无线电装置的设备中发生(如块710所示)。进一步的操作包括把所述多无线电装置的设备配置成：不在非连续接收(DRX)的非调度时段期间针对挂起的上行链路重传而监控多无线电装置的设备中的高功率收发器的物理下行链路控制信道(PDCCH)(如块720所示)。
在另一个实施例中，网络节点800依据本发明的实施例在图8的框图中被图示。网络节点包括耦合到网络节点的辅助接收模块804。辅助接收模块被配置成从无线设备808接收辅助信息。所述辅助信息包括：无线设备为其被配置成与网络节点通信的时分复用(TDM)模式的周期值。DRX有效持续时间模块812被耦合到网络节点并被配置成设置 DRX有效持续时间。DRX有效持续时间可以是TDM模式的周期值的整数倍。DRX配置模块816可以被耦合到网络节点并被配置成把DRX信息传送到无线设备808，用以把所述无线设备配置成提供DRX。DRX信息可以包括DRX有效持续时间。
在另一个实施例中，针对非连续接收配置的多无线电装置的无线设备900依据本发明的实施例在图9的框图中被图示。多无线电装置的无线设备可以包括非连续接收(DRX)模块904，其被配置成从eNodeB 912接收非连续接收配置信息元素(IE)。过程活跃指示符模块908被配置成：在非连续接收(DRX)的非调度时段期间，识别何时针对挂起的上行链路重传而监控多无线电装置的设备中的无线广域网(WWAN)收发器916的物理下行链路控制信道(PDCCH)。多无线电装置的无线设备还可以包括至少一个低功率接收器920，其被配置成：当多无线电装置的设备904中的WWAN收发器916不在DRX的非调度时段期间针对挂起的上行链路重传监控所述PDCCH时接收数据。

各种技术或其某些方面或部分可以采用体现在有形介质(诸如，软盘、CD-ROM、硬盘驱动器、非临时性计算机可读存储介质、或任何其他机器可读存储介质)中的程序代码(即，指令)的形式，其中，当所述程序代码被加载到机器(诸如，计算机)中并且被机器所执行时，所述机器成为用于实施各种技术的装置。在可编程计算机上的程序代码执行的情形下，所述计算设备可以包括：处理器、由处理器可读取的存储介质(包括易失性和非易失性存储器和/或存储元件)、至少一个输入设备、和至少一个输出设备。所述易失性和非易失性存储器和/或存储元件可以是：RAM、EPROM、闪存驱动器、光学驱动器、磁性硬盘驱动器、或用于存储电子数据的其他介质。所述基站和移动设备还可以包括：收发器模块、计数器模块、处理模块、和/或时钟模块或定时器模块。可以实现或使用在此描述的各种技术的一个或多个程序可以使用应用编程接口(API)、可重用控件等。此类程序可以以高级的面向过程或面向对象的编程语言来实现，以与计算机系统进行通信。然而，如果需要，则(一个或多个)程序也可以以汇编或机器语言来实现。在任何情形下，所述语言可以是编译或解释语言，并且与硬件实现方式相结合。
