Abstract

本公开涉及无线通信系统中的用于下行链路协调多点的信令。本文的实施例描述用于在无线网络中支持与用户设备（UE）的下行链路协调多点（CoMP）通信的信令的装置、系统和方法。在实施例中，可对UE配置多个信道状态信息（CSI）进程（例如，经由无线电资源控制（RRC）信令）以用于向演进节点B（eNB）提供CSI反馈来支持下行链路CoMP通信。可对UE配置多组CSI进程。UE可进一步从eNB接收下行链路控制信息（DCI）消息，其指示UE要提供CSI反馈给UE所涉及的配置的CSI进程组中的一个。UE可对于指示的CSI进程组生成CSI反馈，并且在CSI报告中将CSI反馈传送到eNB。

无线通信系统中的用于下行链路协调多点的信令
相关申请的交叉引用
本申请要求2012年5月11日提交的名为“先进无线通信系统和技术”的美国临时专利申请号61/646,223的优先权益，其全部公开通过引用结合于此。
技术领域
本发明的实施例大体上涉及通信的领域，并且更具体地涉及无线通信系统中用于下行链路协调多点通信的信令（signaling）。
背景技术
为了改进无线网络中的各种操作参数而开发了协调多点（CoMP）系统。有三个类型的CoMP系统：联合传输（JT）；动态点选择（DPS）；和协同调度与协同波束形成（CS/CB）。在JTCoMP中，服务点（例如，增强节点基站（eNB））和协调点（例如，另一个eNB）两者可发送相同的数据给用户设备（UE）。在DPSCoMP中，传输点可在例如宏节点eNB和微微节点eNB的不同候选者之中动态选择。在CS/CBCoMP中，协调节点可抑制干扰信道的干扰。然而，eNB可能对于与UE的CoMP通信的有效管理不具有充分的控制和信令机制。
附图说明
实施例将通过下列详细描述连同附图而容易理解。为了便于该描述，类似的标号指代类似的结构元件。实施例通过示例而非限制的方式在附图的图中图示。

具体实施方式
本公开的说明性实施例包括但不限于用于在无线通信网络中信令来支持下行链路协调多点通信的方法、系统、计算机可读介质和装置。
说明性实施例的各种方面将使用通常由本领域内技术人员采用的术语描述来向本领域内其他技术人员传达他们的工作的实质。然而，替代实施例可仅用描述的方面中的一些实践，这对于本领域内技术人员将是明显的。为了说明的目的，阐述具体数字、材料和配置以便提供对说明性实施例的全面理解。然而，替代实施例可在没有具体细节的情况下实践，这对于本领域内技术人员将是明显的。在其他实例中，省略或简化众所周知的特征以便不掩盖说明性实施例。
此外，各种操作将进而采用对于理解说明性实施例最有帮助的方式描述为多个分立操作；然而，描述的顺序不应该解释为暗示这些操作必定依赖于顺序。特别地，这些操作不需要按呈现的顺序进行。
重复使用短语“在一些实施例中”。该短语一般不指相同的实施例；然而，它可指相同的实施例。术语“包括”、“具有”和“包含”是同义的，除非上下文另外指示。短语“A和/或B”意思是（A）、（B）或（A和B）。短语“A/B”意思是（A）、（B）或（A和B），与短语“A和/或B”相似。短语“A、B和C中的至少一个”意思是（A）、（B）、（C）、（A和B）、（A和C）、（B和C）或（A、B和C）。短语“（A）B”意思是（B）或（A和B），即A是可选的。
尽管已经在本文说明和描述具体实施例，本领域内普通技术人员将意识到很多种替代和/或等同实现可代替示出和描述的具体实施例，而不偏离本公开的实施例的范围。本申请意在涵盖本文论述的实施例的任何适配或变化。因此，明显地规定本公开的实施例仅由权利要求及其等同所限制。
如本文使用的，术语“模块”可指代以下各项、是以下各项的一部分或包括以下各项：专用集成电路（ASIC）、电子电路、执行一个或多个软件或固件程序的处理器（共享、专用或群组）和/或存储器（共享、专用或群组）、组合逻辑电路和/或提供描述的功能性的其他适合部件。
图1示意图示根据各种实施例的无线通信网络100。无线通信网络100（在下文，“网络100”）可以是第3代合作伙伴计划（3GPP）长期演进（LTE）网络的接入网络，例如演进通用地面无线电接入网络（EUTRAN）等。该网络100可包括基站，例如增强节点基站（eNB）104，其配置成与用户设备（UE）108无线通信。
至少在最初，eNB104可具有与UE108建立的无线连接，并且可在CoMP测量集内作为服务节点而操作。网络100的一个或多个额外的eNB（例如，eNB112和116）也可包括在CoMP测量集内。eNB112和116可配置成通过与eNB104协调而便于与UE108无线通信。该一个或多个另外的eNB可统称为“协调节点”。eNB可在协调和服务节点角色之间转变。
服务节点和协调节点可通过无线连接和/或有线连接（例如，高速光纤回程连接）互相通信。
这些eNB可分别具有大体上彼此相同的传输功率能力，或备选地，这些eNB中的一些可具有相对低的传输功率能力。例如，在一个实施例中，eNB104可以是例如宏eNB等相对高功率的基站，而eNB112和116可以是相对低功率基站，例如微微eNB和/或毫微微eNB。
eNB104可配置成通过一个或多个分量载波而与UE108通信。每个分量载波可与在该分量载波上用于通信的频带关联。在一些实施例中个体分量载波可视为单独小区。在一些实施例中，eNB104可使用载波聚合而通过多个分量载波（具有不同频率）与UE108通信。UE108可在主服务小区上接收控制信息，并且可在辅服务小区上接收其他信息。该主和辅服务小区可与相应分量载波关联。除CoMP通信外还可使用载波聚合，或可使用载波聚合来代替CoMP通信。
UE108可包括互相耦合的通信模块120和反馈模块124。UE108可进一步包括与通信模块120和/或反馈模块124耦合的CoMP模块128。通信模块120可进一步与UE108的多个天线132中的一个或多个耦合用于通过网络100无线通信。
UE108可包括任何适合数量的天线。在各种实施例中，UE108可包括至少与由UE108从eNB接收的同步空间层或流（simultaneousspatiallayerorstream）的数量一样多的天线，但本公开的范围在该方面可不受限制。同步空间层或流的数量也可称为传输秩，或简单地称为秩。
天线132中的一个或多个可交替地用作发送或接收天线。备选地或另外，天线132中的一个或多个可以是专用接收天线或专用发送天线。
eNB104可包括至少如示出的那样互相耦合的通信模块136、CoMP管理模块140和非周期性反馈模块144。通信模块136可进一步与eNB104的多个天线152中的一个或多个耦合。通信模块136可与一个或多个UE（例如，UE108）通信（例如，发送和/或接收）。在各种实施例中，eNB104可包括至少与传送到UE108的同步传输流的数量一样多的天线，但本公开的范围在该方面可不受限制。天线152中的一个或多个可交替地用作发送或接收天线。备选地或另外，天线152中的一个或多个可以是专用接收天线或专用发送天线。
在各种实施例中，UE108可配置成具有针对个体小区（例如，分量载波）的一个或多个CSI进程。CSI进程可包括关联的CSI参考信号（CSI-RS）资源和/或关联的CSI干扰测量（CSI-IM）资源。在一些实施例中，CSI-RS资源可以是非零功率（NZP）CSI-RS资源。UE108可进一步接收与每个配置的CSI进程关联的小区索引和/或CSI进程标识符（ID）（例如，在给定小区内）。可使用更高层信令（例如经由无线电资源控制（RRC）信令）来对UE108配置一个或多个CSI进程（例如，由eNB104）。CSI进程可供UE108使用以便对eNB104生成CSI反馈以便于与UE108的下行链路CoMP通信。
在各种实施例中，UE108的反馈模块124可经由通信模块120而从eNB104接收下行链路控制信息（DCI）消息。可例如在物理下行链路控制信道（PDCCH）上接收DCI消息。在一些实施例中，PDCCH可以是增强型PDCCH（EPDCCH）或其他类型的PDCCH。DCI消息可包括CSI请求字段，用于指示UE108向eNB104提供CSI反馈所针对的一个或多个CSI进程。因此，DCI消息可便于由UE108非周期地报告CSI反馈。在一些实施例中，CSI请求字段可以是两个位，用于指示四个可能值中的一个。CSI请求字段的其他实施例可包括其他数量的位。
反馈模块124可对指示的CSI进程生成CSI反馈。CSI反馈可包括，例如CSI进程的信道质量指示符（CQI）、预编码矩阵指示符（PMI）、一个或多个选择的子带和/或秩指示符（RI）。反馈模块124然后可经由通信模块120将包括生成的CSI反馈的CSI报告传送到eNB104。CSI报告可例如在物理上行链路共享信道（PUSCH）上传送。
图2图示根据一些实施例映射两位CSI请求字段的值的表格200。如在表格200中示出的，CSI请求字段可具有值“01”，用于指示反馈模块124要针对为UE108的服务小区配置的第一组CSI进程提供CSI报告。服务小区可以是主服务小区，UE108在其上接收包括CSI请求字段的DCI。在一些实施例中，UE108可基于UE108在其上接收DCI的分量载波来识别UE108要为其提供CSI反馈的服务小区。
在一些实施例中，值“01”可指示UE108要针对与服务小区关联的CSI进程中的全部（例如，第一组CSI进程可包括与服务小区关联的所有CSI）提供CSI反馈。在其他实施例中，该第一组CSI进程可包括与服务小区关联的CSI进程的子集（例如，比全部要少）。例如，可经由更高层（例如，经由RRC信令）对UE108配置该第一组CSI进程。
在各种实施例中，CSI请求字段可具有值“10”，用于指示反馈模块124要提供第二组CSI进程的CSI报告。备选地，CSI请求字段可具有值“11”，用于指示反馈模块124要提供第三组CSI进程的CSI报告。第二组和/或第三组CSI进程可由更高层（例如，RRC信令）、例如由eNB104配置，来指示包括在第二和/或第三组中的CSI进程。
对于第一组、第二组和/或第三组的CSI报告可由eNB104使用来管理与UE108的下行链路CoMP通信。在一些实施例中，除CoMP通信外，对于第一组、第二组和/或第三组的CSI报告还可由eNB104使用来管理与UE108的载波聚合通信。CSI请求字段可与用于触发CSI报告来支持载波聚合通信的CSI请求字段相似。然而，用于载波聚合的CSI请求字段可只触发对于特定小区或小区组的一个CSI进程的CSI报告，并且可不允许触发与给定小区关联和/或与不同小区关联的超过一个CSI进程的CSI报告。此外，第二和/或第三组CSI进程可包括具有相同频率的不同小区（例如，不同eNB传送的具有相同频率的小区）上的CSI进程。
在一些实施例中，如本文描述的CSI请求字段可在采用传输模式10（如在LTE高级版本11中限定的）配置UE108时使用。传输模式10可支持与UE的CoMP通信。在传输模式10中，UE108可如本文描述的那样提供一个或多个CSI进程的CSI反馈。UE108可使用DCI格式2D来接收调度信息。在一些实施例中，DCI格式1A可用作后退模式。UE108还可接收除服务小区外的其他小区的PDSCH映射参数。另外或备选地，UE108可使用特定UE特定的参考信号用于PDSCH的解调。
第二组和/或第三组CSI进程可包括任何数量的一个或多个CSI进程。在一些实施例中，该第二组和/或第三组可包括多个CSI进程。在一些实施例中，该第二组和第三组可包括一个或多个公共CSI进程（例如，包括在该第二组和第三组两者中的一个或多个CSI）。在其他实施例中，该第二组和第三组每个可只包括一个CSI进程。该第二组和/或第三组的CSI进程可包括与不同于服务小区的小区关联的一个或多个CSI进程。另外或备选地，该第二组和/或第三组可包括与不同小区关联的多个CSI进程。
在各种实施例中，CSI请求字段可包括值“00”，用于指示DCI消息没有触发非周期性CSI报告。值“00”可例如在将DCI消息传送到UE108用于除触发非周期CSI报告之外的另一个目的时使用。
尽管两位CSI请求字段的特定值在表格200中示出，这些值可采用任何适合的方式映射到与表格200中示出的可以不同的对应动作，这将是明显的。例如，在另一个实施例中，值“00”可触发第一组CSI进程的CSI报告。
如本文描述的，CSI请求字段可由eNB104使用来触发第一组CSI进程的CSI报告。eNB104可动态改变eNB104请求来自UE104的CSI反馈所针对的那组CSI进程。eNB104的非周期性反馈模块144可接收CSI报告并且CoMP管理模块140可使用包括在CSI报告中的CSI反馈信息来管理与UE的下行链路CoMP通信。
在其他实施例中，CSI请求字段可只包括一个位。该位可具有第一值（例如，“1”），用于触发服务小区的所有CSI进程的CSI报告。如果DCI消息未触发CSI报告，则该位可具有第二值（例如，“0”）。可例如在UE108使用其中对于PDCCH解码具有公共搜索空间（如与UE特定的搜索空间不同）的传输模式时使用一位CSI请求字段。
图3图示根据另一个实施例映射两位CSI请求字段的值的表格300。如在图3中示出的，该两位CSI请求字段可包括值“01”，用于指示UE108要提供第一组CSI进程的CSI报告，或值“10”，用于指示UE108要提供第二组CSI进程的CSI报告。CSI请求字段可进一步包括值“11”，用于指示UE108要提供第一组和第二组进程两者的CSI报告。CSI请求字段可包括值“00”，用于指示DCI消息未触发非周期性CSI报告。
除在图2和3中示出的配置之外，CSI请求字段的其他适合的配置可用于触发不同组的CSI进程的非周期性CSI报告，这将是明显的。例如，在另一个实施例中，CSI请求字段可与在表格300中示出的相似，但其中值“00”指示UE108要提供为服务小区配置的一组CSI进程的CSI报告。
在各种实施例中，可由CSI请求字段为CSI报告所触发的CSI进程组（例如，上文描述的第一、第二和/或第三组）可由eNB104使用相应的位图来配置。这些位图可由eNB104（例如，经由RRC信令）传送到UE108来指示哪些CSI进程包括在给定的CSI进程组中。例如，图4图示根据各种实施例的位图400。位图400包括多个位（例如，位b0、b1、…bNK-1）并且个体位可对应于个体CSI进程来指示该CSI进程是否包括在由位图400限定的CSI进程组中。可根据位索引（例如，按小区索引的升序）在位图400中对位进行排序，并且对应于与相同小区索引关联的CSI进程的位可由它们相应的CSIID而排序。例如，位图400包括对应于K+1个分量载波（例如，具有小区索引0至小区索引K）的位。每个分量载波可包括最大N个配置的CSI进程。对应于具有相同小区索引的CSI进程的位群组在位图400中按小区索引的升序设置（例如，其中对应于小区索引0的CSI进程的位(b0-bN-1)在对应于小区索引1的CSI进程的位(bN-b2N-1)前面设置在位图400中）。在对应于具有相同小区索引的CSI进程的位群组，按CSI进程ID的升序来对位排序。例如，位b0对应于具有小区索引0和CSI进程ID0的CSI进程，并且位b1对应于具有小区索引0和CSI进程ID1的CSI进程，等。
如上文论述的，eNB104可传送与位图400相似的多个位图来限定用于非周期性CSI报告的不同CSI进程组。个体组的非周期性CSI报告然后可由包括如本文描述的CSI请求字段的DCI消息触发。在一些实施例中，用于限定用于非周期性CSI报告的CSI进程组的位图可作为CSI进程配置过程的一部分而被传送（例如，在UE108变成与eNB104RRC连接时）。例如，eNB104的CoMP管理模块140可对于个体CSI进程同时传送位图与CSI进程配置信息（例如，CSI-RS资源和/或CSI-IM资源）。另外或备选地，位图可与CSI进程配置信息分开传送来限定和/或修改用于非周期性CSI报告的CSI进程组。
在一些实施例中，eNB104的CoMP管理模块140可进一步传送与个体CSI进程关联的codebookSubsetRestriction参数。该codebookSubsetRestriction参数可作为CSI进程的配置的一部分而被传送。codebookSubsetRestriction参数可指示在要由UE104使用以用于相应CSI进程的CSI报告的密码本内的PMI的子集。备选地或另外，可对每个NZPCSI-RS资源和/或子帧的子集配置codebookSubsetRestriction参数。
在一些实施例中，eNB104可配置多个配置的CSI进程之间的一个或多个CSI依赖性。例如，eNB104可指示UE108在相同的秩上和/或通过相同优选的子带而报告多个CSI进程的CSI反馈。
如上文论述的，UE108的反馈模块124可对由CSI请求字段触发的一个或多个CIS进程生成CSI反馈。CSI反馈可基于对CSI进程配置的CSI-RS资源和/或CSI-IM资源而生成。CSI反馈可包括，例如CSI进程的CQI、PMI、一个或多个选择的子带和/或RI。UE108可在CSI报告中将CSI反馈传送给eNB104。
在一些实施例中，多个CSI进程的CSI反馈可在相同的CSI报告中级联。例如，多个CSI进程的CSI反馈可根据CSI进程索引和/或CSI进程的小区索引而级联。在一个实施例中，与相同分量载波（例如，具有相同的小区索引）关联的CSI进程群组的CSI反馈可在CSI报告中按小区索引的升序排序。CSI反馈可按具有相同小区索引的个体CSI进程的CSI进程索引的升序设置在个体群组内。
在一些情况下，第一CSI进程的CSI反馈的一个或多个分量可与第二CSI进程的CSI反馈的一个或多个分量相同。例如，对于第一和第二CSI进程报告的RI可以是相同的。在一些实施例中，可从第一CSI进程或第二CSI进程的CSI报告中省略共享分量（例如，在该示例中是RI）。这可减少CSI报告所需要的带宽。
在一些实施例中，可使用turbo编码和/或循环冗余校验（CRC）编码来对CSI报告编码。例如，turbo编码和/或CRC编码可用于对CQI和PMI报告编码。这可便于使得CSI报告具有大的有效载荷长度。
图5是图示根据各种实施例用于触发非周期性CSI反馈的方法500的流程图。方法500可由UE（例如，UE108）进行。在一些实施例中，UE可包括和/或访问一个或多个计算机可读介质，其具有存储在其上的指令，这些指令在执行时使UE进行方法500。另外或备选地，在一些实施例中，UE可包括用于进行方法500的电路。
在504，UE可通过无线通信网络（例如，网络100）从eNB（例如，eNB104）接收第一位图（例如，位图400）。该第一位图可指示包括在第一组CSI进程中的一个或多个CSI进程。例如，该第一位图可包括多个位，并且个体位可对应于个体CSI进程来指示CSI进程是否包括在第一组CSI进程中。个体位可具有第一值（例如，“1”），用于指示对应的CSI进程包括在第一组中，或第二值（例如，“0”），用于指示对应的CSI进程不包括在第一组中。在一些实施例中，可根据CSI进程的小区索引在位图中对多个位排序（例如，按小区索引的升序），并且对应于具有相同小区索引的CSI进程的位可按照CSI进程的CSI进程ID来排序（例如，按CSI进程ID的升序）。
在508，UE可从eNB接收第二位图。该第二位图可指示包括在第二组CSI进程中的一个或多个CSI进程。该第二位图可具有与在上文对于第一位图描述的相似的位设置，但其中不同的位设置成第一值（例如，“1”）。在一些实施例中，第一和第二组可包括一个或多个共同的CSI进程。
在512，UE可从eNB接收DCI消息。该DCI消息可包括CSI请求字段，用于请求CSI反馈来支持到UE的下行链路CoMP传输。在一些实施例中，CSI请求字段可包括两个位，用于形成四个值中的一个。CSI请求字段可具有用于指示UE要对于第一组CSI进程提供CSI反馈（例如，在504处配置的）的第一值，或用于指示UE要对于第二组CSI进程（例如，在508处配置的）提供CSI反馈的第二值。
在516，UE可对由CSI请求字段指示的CSI进程生成CSI反馈。
在520，UE可将生成的CSI反馈传送到eNB。CSI反馈可包括在一个或多个CSI报告中。
在一些实施例中，CSI请求字段可具有用于指示UE要对于为UE的服务小区配置的一组CSI进程提供CSI反馈的第三值。该服务小区可由载波分量识别，eNB在该载波分量上将包括CSI请求字段的DCI传送到UE。对服务小区配置的CSI进程组可包括对服务小区配置的所有CSI进程或对服务小区配置的所有CSI进程的子集。
在一些实施例中，CSI请求字段可具有用于指示DCI消息未触发CSI报告的第四值。
在其他实施例中，CSI请求字段的第三或第四值可用于指示UE要对于第一组和第二组CSI进程（例如，如分别在504和508处配置的）两者都提供CSI反馈。
在各种实施例中，UE108可接收与物理下行链路共享信道（PDSCH）资源元素映射配置有关的信息供UE108使用来接收PDSCH。在一些实施例中，UE108的CoMP模块128可从eNB接收RRC消息，其包括多个PDSCH映射配置的PDSCH资源元素映射参数。PDSCH资源元素映射参数可包括，对于个体PDSCH映射配置的例如小区特定的参考信号（CRS）天线端口数量、CRS天线端口移位、PDSCH开始符号、多播广播单频网子帧配置。在一些实施例中，PDSCH资源元素映射参数可进一步包括与PDSCH映射配置关联的非零功率CSI-RS标识符和/或CSI进程标识符。PDSCH映射配置可进一步（明确地或隐含地）与PDSCH映射配置ID关联。
可对UE108配置任何适合数量的PDSCH映射配置。例如，在一个实施例中，可对UE108配置四个PDSCH映射配置。在一些实施例中，PDSCH映射配置可以是通用的（例如，不与特定小区关联）。在其他实施例中，PDSCH映射配置可与相应的个体小区关联。
在一些实施例中，CRS天线端口的数量和CRS天线端口移位可联合编码到CRS配置参数内。例如，图6图示表格600，其示出CRS配置参数的值映射到CRS天线端口数量和CRS天线端口移位的对应值。如在表格600中示出的，CRS配置参数的第一值（例如，值0）可指示PDSCH映射配置具有4个天线端口和具有2个子帧的CRS频移。在一些实施例中，PDSCH映射配置可具有1、2或4个的天线端口数量。具有1个天线端口的PDSCH映射配置可具有六个CRS频移中的一个（例如，0、1、2、3、4或5个子帧），而具有2或4个天线端口的PDSCH映射配置可具有三个CRS频移中的一个（例如，0、1或2个子帧）。因此，对CRS天线端口数量和CRS天线端口移位的联合编码可需要比单独对它们编码少一个位。
在各种实施例中，UE108可从eNB104接收DCI消息，该DCI消息指示供UE108使用来接收PDSCH的多个PDSCH映射配置的PDSCH映射配置中的一个（例如，第一PDSCH映射配置）。例如，该DCI消息可包括PDSCH映射配置ID，其对应于如上文描述的那样使用RRC信令来配置的PDSCH映射配置中的一个。在一些实施例中，可将该PDSCH映射配置ID与指示多个配置的分量载波中的第一分量载波（PDSCH要在其上传送给UE108）的分量载波指示符联合编码。例如，DCI消息可包括载波聚合小区识别字段（CIF），其指示供UE使用来接收PDSCH的PDSCH映射配置和分量载波。在一些实施例中，CIF可是三个位。该三位CIF可具有八个不同的值来指示两个分量载波中的一个和四个PDSCH映射配置中的一个。在其他实施例中，PDSCH映射配置ID可包括在与CIF分开的字段中。
UE108可使用PDSCH资源元素映射参数来经由CoMP通信而接收PDSCH。例如，PDSCH资源元素映射参数可便于避免CRS与PDSCH冲突。对于联合传输（JT）CoMP，当资源元素静噪（resourceelementmuting）用于减轻CRS与PDSCH冲突时，UE108可使用映射参数来确定瞬时速率匹配模式。对于动态点选择（DPS），映射参数可用于避免对资源元素静噪的需要。另外，对于传输模式1、2、3和4中的DPS，如在LTE-高级标准版本11中提出的，UE108可使用PDSCH资源元素映射参数来确定应该用于PDSCH解调的特定CRS。
在其中PDSCH映射配置与相应个体小区（分量载波）关联的实施例中，可向UE108指示发送小区来指示供UE使用来接收PDSCH的PDSCH映射配置。在一些实施例中，载波聚合CIF可用于指示下行链路CoMP的发送小区（例如，使用不用于载波聚合的CIF的值）。其他位大小和/或设置可用于指示供UE108使用的PDSCH映射配置，这将是明显的。

网络接口720可具有收发器722，用于对系统700提供无线电接口以通过一个或多个网络通信和/或与任何其他适合的设备通信。收发器722可实现UE108的通信模块120或eNB104的通信模块136。在各种实施例中，收发器722可与系统700的其他部件集成。例如，收发器722可包括处理器704的处理器、系统存储器712的存储器以及NVM/存储716的NVM/存储。网络接口720可包括任何适合的硬件和/或固件。网络接口720可包括多个天线，用于提供多输入多输出无线电接口。对于一个实施例的网络接口720可包括例如有线网络适配器（例如，以太网网络适配器）、无线网络适配器、电话调制解调器和/或无线调制解调器。
对于一个实施例，处理器704中的至少一个可与系统控制逻辑708的一个或多个控制器的逻辑封装在一起。对于一个实施例，处理器704中的至少一个可与系统控制逻辑708的一个或多个控制器的逻辑封装在一起来形成系统级封装（SiP）。对于一个实施例，处理器704中的至少一个可集成在与系统控制逻辑708的一个或多个控制器的逻辑相同的芯片上。对于一个实施例，处理器704中的至少一个可集成在与系统控制逻辑708的一个或多个控制器的逻辑相同的芯片上来形成芯片上系统（SoC）。对于一个实施例，处理器704中的至少一个可与NVM/存储716的存储器封装在一起来形成层叠封装（PoP）。例如，存储器可与应用处理器耦合并且可以与该应用处理器一起配置为PoP。
