Description

一种资源分配装置、系统及方法
本申请要求于2014年10月24日提交中国专利局、申请号为201410579374.3、发明名称为“一种资源分配装置、系统及方法”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
本发明涉及通信技术领域，具体涉及一种资源分配装置、系统及方法。
背景技术
长期演进(Long Term Evaluation，LTE)系统中，采用共享式资源分配方式利用无线通信资源时，每次传输都需要相关的控制信息，而且上行的资源相对有限。针对数据包大小比较固定，到达时间间隔满足一定规律的实时性业务，LTE系统引入新的资源分配方式，即半静态调度技术，简单而言，半静态调度是指在LTE的资源传输过程中，基站在初始时是通过控制信道区域指示用户设备当前的资源分配信息，当用户设备识别是半静态调度时，则保存当前的资源分配信息，每隔固定的周期在相同的时频资源位置上进行该业务数据的发送或接收，因此，使用半静态调度，可以充分利用数据包周期性到达的特点，一次授权，周期使用，可以有效的节省LTE系统用于分配指示的控制信道区域资源，而虚拟多发多收技术(Virtual Multiplex Input Multiplex Output，VMIMO)技术是一种资源调度复用技术，解决了上行资源有限的问题，VMIMO允许两个或两个以上的用户设备进行虚拟绑定，使用相同的时频资源来传输数据。
以典型的语音通话(Voice Over IP，VoIP)业务举例，目前支持VoIP业务容量的上行资源基本上采用半静态调度，其数据包到达周期为20ms，即每间隔20ms的VoIP数据包采用相同的调制与编码策略方式(Modulation and Coding Scheme，MCS)与无线链路承载(Radio Bear，RB)位置予以调度，但由于VoIP采用半静态之后的MCS不发生变化，而VMIMO由于不同用户设备间的干扰影响，若保证一定的误包收敛，MCS需随配对用户设备信息产生变化，当前VoIP的半静态与VMIMO无法兼容配合，使得VoIP的容量受限。

具体实施方式
本发明实施例提供了一种资源分配装置、系统及方法，用于解决VMIMO与VoIP的半静态调度不兼容的问题，提升VoIP容量。
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本发明实施例应用的通信系统可以是基于LTE或者其他通信系统所作出的改进，本文对此不做限制。可以理解的，本发明实施例适用于LTE系统，以及基于IP的其他无线通信系统(即能够支持VoIP业务的其他系统)等。本发明实施例可应用于上行资源有限的情况下，通过VMIMO和VoIP兼容配合，既解决了上行资源有限的问题，又解决了控制信道区域负载大的问题，从而增大了VoIP的容量。
请参阅图1，本发明实施例中资源分配装置100的一个实施例，包括确定单元101和分配单元102。
确定单元101用于：确定需要进行上行传输的用户设备所需的资源块的个数；
在本发明实施例中，先确定需要进行上行传输的用户设备所需的资源块 的个数过程是：比如对用户设备进行上行传输基本上采用半静态调度，则数据包到达的周期为20ms，若以G.72964K的语音编码为例，即，20ms产生20×64＝1280bits的数据包，根据用户设备所处的信道条件预估用户设备的MCS，其中，信道条件可以转化为RB频率效率等，再根据用户设备的MCS确定用户设备进行上行传输所需的资源块的个数，其中，需要进行上行传输的第一用户设备和需要进行上行传输的第二用户设备所需的资源块的个数均为M，M为正整数，即1个RB，2个RB，3个RB等，还可以进一步确定上行传输所包括的RB资源块的个数，即1个RB的RB资源块个数，2个RB的RB资源块个数，3个RB的RB资源块个数等。
需要说明的是，在本发明实施例中，进行上行传输的资源可以是VoIP数据包，也可以是其他数据包，此处不做具体限定。
需要说明的是，该资源块可以是RB资源块，也可以是其他资源块，此处不做具体限定。
分配单元102用于：确定单元101确定需要进行上行传输的用户设备所需的资源块的个数后，将第一资源组中的第一子组的资源块分配给第一用户设备，将第一资源组中的第二子组的资源块分配给第二用户设备，第一资源组由包括第一子组和第二子组在内的多个子组组成，每个子组由M个资源块组成。
在本发明实施例中，进一步地，基站将同一个资源组中的不同子组的资源块分配给至少两个用户设备，比如，如果需要进行上行传输的第一用户设备和需要进行上行传输的第二用户设备所需的资源块的个数均为2，其实，该资源块的个数为实体，即，将第一子组的2个资源块分配给第一用户设备，将第二子组中的2个资源块分配给第二用户设备，实际上，每个资源组包括多个相同资源块的子组，比如是1个RB的RB资源组，2个RB的RB资源组，其中，1个RB的RB资源组中有多个子组，每个子组有1个RB，2个RB的RB资源组中有多个子组，每个子组有2个RB。
本发明实施例先通过确定单元确定需要进行上行传输的用户设备所需的资源块的个数后，其中，需要进行上行传输的第一用户设备和需要进行上行传输的第二用户设备所需的资源块的个数均为M，M为正整数，再通过分配单元将第一资源组中的第一子组的资源块分配给第一用户设备，将第一资源组中 的第二子组的资源块分配给第二用户设备，由于第一资源组由包括第一子组和第二子组在内的多个子组组成，并且每个子组由M个资源块组成。即可以将第一资源组中多个子组的资源块分配给多个用户设备，解决了现有技术中的VMIMO与VoIP的半静态调度无法兼容的问题，从而提升VoIP容量。
请参阅图2，本发明实施例中资源分配装置200的一个实施例，包括：确定单元201，设置单元202，选择单元203，分配单元204。
确定单元201用于：确定需要进行上行传输的用户设备所需的资源块的个数；
在本发明实施例中，先确定需要进行上行传输的用户设备所需的资源块的个数的过程是：可以先根据用户设备所处的信道条件预估用户设备的MCS，其中，信道条件可以转化为RB频率效率等，再根据用户设备的MCS确定用户设备进行上行传输所需的资源块的个数，其中，需要进行上行传输的第一用户设备和需要进行上行传输的第二用户设备所需的资源块的个数均为M，M为正整数。
设置单元202用于：确定单元201确定需要进行上行传输的用户设备所需的资源块的个数后，设置第一资源组和至少一个其他资源组，所述至少一个其他资源组中的每个其他资源组均由多个子组组成，所述每个其他资源组内的多个子组中的资源块的数量相同，所述第一资源组和至少一个其他资源组各自的子组中的资源块的数量不同。
进一步地，本发明实施例需要设置资源组，通过设置资源组，将每个资源组中多个子组的资源块分别分配给多个用户设备，解决了现有技术中的兼容问题，而且提高了VoIP容量。
选择单元203用于：设置单元202设置第一资源组和至少一个其他资源组后，在设置的资源组中选择第一资源组，选择的条件为：资源组中的子组由M个资源块组成。
进一步地，由于基站侧的不同资源组中的资源块的个数是不同的，即，根据第一用户设备和第二用户设备进行上行传输所需的资源块的个数，选择相应的资源组。
分配单元204包括：第一确定子单元2041和/或第二确定子单元2042。其 中，第一确定子单元2041用于：确定所述第一用户设备处于激活的半静态；第二确定子单元2042用于：确定所述第二用户设备处于激活的半静态；
进一步地，由于处于激活的半静态的用户设备才可以进行上行传输，如果用户设备不处于激活的半静态时，则需要进一步根据该用户设备所需的资源块的个数，并选择相应的资源组。
分配单元204具体用于：选择单元203在设置的资源组中选择第一资源组后，在所述第一确定子单元2041确定所述第一用户设备处于激活的半静态时，将第一资源组中的第一子组的资源块分配给所述第一用户设备，以及，在所述第二确定子单元2042确定所述第二用户设备处于激活的半静态时，将所述第一资源组中的第二子组的资源块分配给所述第二用户设备。
进一步地，将第一资源组中的第一子组的资源块分配给所述第一用户设备，将所述第一资源组中的第二子组的资源块分配给所述第二用户设备可以理解成用户设备的配对分配资源，即将同一个资源组的资源块分配给至少两个用户设备，即第一用户设备和第二用户设备获取同样大小的资源块，完成资源的配对分配，不仅解决了现有技术中的兼容问题，还可以提高业务容量，比如，容量的提升在于空分复用，给第一用户设备分配100个RB，给第二用户设备分配100RB，这样就成了200RB，容量自然提升。
需要说明的是，在一些实施例中，分配单元204还可以包括：判断子单元2043和分配子单元2044。
判断子单元2043用于：判断所述第一用户设备发生解析错误的数据包的个数是否大于第一门限值，和/或，所述第一用户设备的丢包率是否大于第二门限值；其中，丢包率为：在预设时间内发生解析错误的数据包的个数与在所述预设时间内接收到的数据包的总个数的比值；
分配子单元2044用于：在所述判断子单元确定所述第一用户设备发生解析错误的数据包的个数第一门限值和/或所述第一用户设备的丢包率是否大于第二门限值时，将第二资源组中的第一子组的资源块分配给所述第一用户设备，所述第二资源组中的第一子组的资源块的个数为M加1。
在本发明实施例中，如果第一用户设备发生解析错误的数据包的个数大于第一门限值或第一用户设备的丢包率大于第二门限值，则将该第一用户设备所 需的资源块的个数加1，比如之前确定第一用户设备的资源块的个数为1，将1个资源块的资源组中的一个子组的1个资源块分配给第一用户设备，后修正第一用户设备的资源块的个数为2，并将2个资源块的资源组中的一个子组的2个资源块分配给第一用户设备，其中，丢包率为：在预设时间内发生解析错误的数据包的个数与在所述预设时间内接收到的数据包的总个数的比值，比如在1秒内发生解析错误的数据包的个数与在1秒内接收到的数据包的总个数的比值。
需要说明的是，如果第二用户设备发生解析错误的数据包的个数大于第一门限值和/或第二用户设备的丢包率大于第二门限值时，将第二资源组中的第二子组的资源块分配给第二用户设备，所述第二资源组中的第二子组的资源块的个数为M加1，具体此处不做限定。
需要说明的是，在对除第一用户设备和第二用户设备分配以外的后续的分配资源时，由于没有触发控制信道区域调度行为，只需在相同的时频上分配资源即可。
需要说明的是，该资源分配装置为基站。
本发明实施例中，先通过确定单元确定需要进行上行传输的用户设备所需的资源块的个数，而在相应的基站侧，通过设置单元设置第一资源组和至少一个其他资源组，再通过选择单元在设置的资源组中选择所述第一资源组，即选择子组由M个资源块组成的资源组，进一步地，通过确定第一用户设备处于激活的半静态后，通过分配单元将第一资源组中的第一子组的资源块分配给所述第一用户设备，第二用户设备处于激活的半静态后，将所述第一资源组中的第二子组的资源块分配给所述第二用户设备，由于第一资源组由包括第一子组和第二子组在内的多个子组组成，并且每个子组由M个资源块组成。即可以将第一资源组中多个子组的资源块分配给多个用户设备，解决了现有技术中的VMIMO与VoIP的半静态调度无法兼容的问题，从而提升VoIP容量。
本发明实施例还提供一种资源分配系统，包括如上述所述的资源分配装置和用户设备，具体实施例可以参照上述资源分配装置的实施例，此处不再赘述。
图1至图2所示的实施例从功能模块的角度对资源分配装置的具体结构进 行了说明，以下结合图3的实施例从硬件角度对资源分配装置的具体结构进行说明：

确定需要进行上行传输的用户设备所需的资源块的个数；
将第一资源组中的第一子组的资源块分配给所述第一用户设备，将所述第一资源组中的第二子组的资源块分配给所述第二用户设备，所述第一资源组由包括所述第一子组和所述第二子组在内的多个子组组成，每个子组由M个资源块组成。
在一些实施方式中，处理器301还可以执行以下步骤：

在一些实施方式中，处理器301还可以执行以下步骤：

前面介绍了资源分配的装置的实施例，下面进一步介绍资源分配的方法的实施例，请参阅图4，本发明实施例中资源分配方法的一个实施例包括：步骤401和步骤402。
401、确定需要进行上行传输的用户设备所需的资源块的个数；
在本发明实施例中，确定需要进行上行传输的用户设备所需的资源块的个数的过程为：比如对用户设备进行上行传输基本上采用半静态调度，则数据包到达的周期为20ms，若以G.729 64K的语音编码为例，即，20ms产生20×64＝1280bits的数据包，根据用户设备所处的信道条件预估用户设备的MCS，其中，信道条件可以转化为RB频率效率等，再根据用户设备的MCS确定用户设备进行上行传输所需的资源块的个数，其中，需要进行上行传输的第一用户设备和需要进行上行传输的第二用户设备所需的资源块的个数均为M，M为正整数，即1个RB，2个RB，3个RB等，还可以进一步确定上行传输所包括的RB资源块的个数，即1个RB的RB资源块个数，2个RB的RB资源块个数，3个RB的RB资源块个数等。
需要说明的是，在本发明实施例中，进行上行传输的资源可以是VoIP语音数据，也可以是其他数据，此处不做具体限定。

402、将第一资源组中的第一子组的资源块分配给第一用户设备，将第一资源组中的第二子组的资源块分配给第二用户设备；
在本发明实施例中，第一资源组由包括所述第一子组和所述第二子组在内 的多个子组组成，每个子组由M个资源块组成，进一步地，基站将同一个资源组中的不同子组的资源块分配给至少两个用户设备，比如，如果需要进行上行传输的第一用户设备和需要进行上行传输的第二用户设备所需的资源块的个数均为2，则分别将第一子组和第二子组中的两个资源块分配给第一用户设备和第二用户设备，实际上，每个资源组包括多个相同资源块的子组，比如是1个RB的RB资源组，2个RB的RB资源组，其中，1个RB的RB资源组中有多个子组，每个子组有1个RB，2个RB的RB资源组中有多个子组，每个子组有2个RB。
本发明实施例先确定需要进行上行传输的用户设备所需的资源块的个数后，其中，需要进行上行传输的第一用户设备和需要进行上行传输的第二用户设备所需的资源块的个数均为M，M为正整数，再将第一资源组中的第一子组的资源块分配给第一用户设备，将第一资源组中的第二子组的资源块分配给第二用户设备，由于第一资源组由包括第一子组和第二子组在内的多个子组组成，并且每个子组由M个资源块组成。即可以将第一资源组中多个子组的资源块分配给多个用户设备，解决了现有技术中的VMIMO与VoIP的半静态调度无法兼容的问题，从而提升VoIP容量。
请参阅图5，本发明实施例的资源分配方法的一个具体应用场景实施例包括：步骤501至步骤507。
501、确定需要进行上行传输的用户设备所需的资源块的个数；
在本发明实施例中，确定需要进行上行传输的用户设备所需的资源块的个数是：可以先根据用户设备所处的信道条件预估用户设备的MCS，其中，信道条件可以转化为RB频率效率等，再根据用户设备的MCS确定用户设备进行上行传输所需的资源块的个数，其中，需要进行上行传输的第一用户设备和需要进行上行传输的第二用户设备所需的资源块的个数均为M，M为正整数。
502、设置第一资源组和至少一个其他资源组；
在本发明实施例中，至少一个其他资源组中的每个其他资源组均由多个子组组成，每个其他资源组内的多个子组中的资源块的数量相同，第一资源组和至少一个其他资源组各自的子组中的资源块的数量不同。
进一步地，本发明实施例需要设置资源组，通过设置资源组，将每个资源 组中多个子组的资源块分别分配给多个用户设备，解决了现有技术中的兼容问题，而且提高了VoIP容量。
503、在设置的资源组中选择第一资源组；
在本发明实施例中，选择的条件为：资源组中的子组由M个资源块组成。
进一步地，由于基站侧的不同资源组中的资源块的个数是不同的，即，根据第一用户设备和第二用户设备进行上行传输所需的资源块的个数，选择相应的资源组。
504、确定第一用户设备处于激活的半静态；
在本发明实施例中，由于处于激活的半静态的用户设备才可以进行上行传输，如果用户设备部不处于激活的半静态时，则需要进一步根据该用户设备所需的资源块的个数，并选择相应的资源组。
505、将第一资源组中的第一子组的资源块分配给第一用户设备，将第一资源组中的第二子组的资源块分配给第二用户设备；
在本发明实施例中，将第一资源组中的第一子组的资源块分配给所述第一用户设备，将所述第一资源组中的第二子组的资源块分配给所述第二用户设备可以理解成用户设备的配对分配资源，其中，第一资源组由包括第一子组和第二子组在内的多个子组组成，每个子组由M个资源块组成。即将同一个资源组的资源块分配给至少两个用户设备，即第一用户设备和第二用户设备获取同样大小的资源块，完成资源的配对分配，不仅解决了现有技术中的兼容问题，还可以提高业务容量，比如，容量的提升在于空分复用，给第一用户设备分配100个RB，给第二用户设备分配100RB，这样就成了200RB，容量自然提升。
需要说明的是，将第一资源组中的第二子组的资源块分配给第二用户设备之前，需要确定第二用户设备处于激活的半静态。
506、判断第一用户设备发生解析错误的数据包的个数是否大于第一门限值，若是，执行步骤507；
可选的，如果第一用户设备的丢包率大于第二门限值，则也执行步骤507。
可以理解的是，丢包率为：在预设时间内内发生解析错误的数据包的个数与在所述预设时间内接收到的数据包的总个数的比值，比如在1秒内，发生解析错误的数据包的个数与在1秒内接收到的数据包的总个数的比值大于第二门 限值，则执行步骤507。
507、将第二资源组中的第一子组的资源块分配给第一用户设备。
在本发明实施例中，如果第一用户设备发生解析错误的数据包的个数大于第一门限值或者第一用户设备的丢包率大于第二门限值，则将该第一用户设备所需的资源块的个数加1，比如之前确定第一用户设备的资源块的个数为1，那么在资源分配时，将1个资源块的资源组中的一个子组的1个资源块分配给第一用户设备，后则修正第一用户设备的资源块的个数为2，并将2个资源块的资源组中的一个子组的2个资源块分配给第一用户设备。
需要说明的是，如果第二用户设备发生解析错误的数据包的个数大于第一门限值和/或第二用户设备的丢包率大于第二门限值时，将第二资源组中的第二子组的资源块分配给第二用户设备，所述第二资源组中的第二子组的资源块的个数为M加1，具体此处不做限定。
本发明实施例中，先确定需要进行上行传输的用户设备所需的资源块的个数，而在相应的基站侧，设置第一资源组和至少一个其他资源组，再在设置的资源组中选择所述第一资源组，即选择子组由M个资源块组成的资源组，进一步地，通过确定第一用户设备处于激活的半静态后，将第一资源组中的第一子组的资源块分配给所述第一用户设备，第二用户设备处于激活的半静态后，将所述第一资源组中的第二子组的资源块分配给所述第二用户设备，由于第一资源组由包括第一子组和第二子组在内的多个子组组成，并且每个子组由M个资源块组成。即可以将第一资源组中多个子组的资源块分配给多个用户设备，解决了现有技术中的VMIMO与VoIP的半静态调度无法兼容的问题，从而提升VoIP容量。
以上，本发明实施例先通过确定单元确定需要进行上行传输的用户设备所需的资源块的个数后，其中，需要进行上行传输的第一用户设备和需要进行上行传输的第二用户设备所需的资源块的个数均为M，M为正整数，再将第一资源组中的第一子组的资源块分配给第一用户设备，分配单元将第一资源组中的第二子组的资源块分配给第二用户设备，由于第一资源组由包括第一子组和第二子组在内的多个子组组成，并且每个子组由M个资源块组成。即可以将第一资源组中多个子组的资源块分配给多个用户设备，解决了现有技术中的 VMIMO与VoIP的半静态调度无法兼容的问题，从而提升VoIP容量。
