技术领域
本发明实施例涉及无线通信领域，并且更具体地，涉及资源调度的方法、基站和用户设备。
背景技术
长期演进(Long Term Evolution，LTE)系统引入了正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)和多输入多输出(Multi-Input&Multi-Output，MIMO)等关键技术，显著的增加了频率效率和数据传输速率，系统容量和覆盖范围也得到显著提升。
随着LTE用户的增加，对系统容量的需求越来越大。虽然提升系统容量可通过增加带宽来实现，但由于频谱资源有限，如何在有限的频谱资源下尽可能的提升系统容量成为关注热点。
LTE上行链路中的虚拟多输入多输出(Virtual Multi-Input&Multi-Output，VMIMO)技术可将多个用户配对，在相同时频资源上传输多个用户的数据，在不增加带宽的情况下显著提升小区吞吐量。
但是当采用了VMIMO技术后，配对用户的功率叠加，会导致小区间干扰显著增加，并且随着配对层数的增加，导致干扰源数目增加，最终导致接收机的干扰抑制效果下降，使得VMIMO系统边缘用户设备(User Equipment，UE)吞吐量和性能大幅下降，配对层数越高，边缘UE性能下降越显著。
因此，如何在尽可能不损失VMIMO系统容量的情况下，提升边缘UE的吞吐量和性能是亟待解决的问题。

具体实施方式
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，所描述的实施例是本发明的一部分实施例，而不是全部实施例。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的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
本发明的技术方案，可以应用于各种通信系统，例如：全球移动通讯系统(GSM，Global System of Mobile communication)，码分多址(CDMA，Code Division Multiple Access)系统，宽带码分多址(WCDMA，Wideband Code Division Multiple Access Wireless)，通用分组无线业务(GPRS，General Packet Radio Service)，长期演进(LTE，Long Term Evolution)等。
用户设备(UE，User Equipment)，也可称之为移动终端(Mobile Terminal)、移动用户设备等，可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，用户设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。
基站，可以是GSM或CDMA中的基站(BTS，Base Transceiver Station)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)，本发明并不限定。
MIMO技术作为实现LTE的一项关键技术可以明显地提高系统的容量和频谱效率，能很好的解决无线资源紧张的局面。在实际的移动通信系统中，基站侧受到的限制较少，从而可以采用多根发射和接收天线，同时各天线互相之间具有较好的隔离度，因此MIMO技术的优势可以在下行链路上得到很好的发挥。然而在用户侧，如果终端设备配置多个天线，一方面受到终端设备体积、续航能力以及辐射等因素的限制；另一方面每个天线上的大尺度衰落变化会非常明显，天线之间的隔离度较差。基于这种情况，上行链路一般不能充分利用MIMO技术的优点。VMIMO技术使得多个用户之间可以通过共享各自的天线，构成虚拟的多天线发送和多天线接收的通信系统，即使用户只有一个天线，传输信息时只要进行有效的合作也可以实现MIMO的主要功能。
VMIMO技术通过采用特定的调度机制，按照一定规则选择不同的用户配对成为一组，构成一个共享时频资源的虚拟多天线阵列。通过该虚拟多天线阵列在相同的时频资源上发送数据，形成无线信号的空间复用，通过空间复用增益来提高系统容量和频谱效率。
图1是本发明一个实施例的资源调度的方法的流程图。图1的方法由基站执行。
101，基站接收用户设备UE发送的调度请求。
102，基站确定UE的调度类型，调度类型为边缘UE或者非边缘UE。
103，基站根据UE的调度类型，以及UE的服务小区的频率资源配置，为UE调度频率资源，其中，UE的服务小区的频率资源配置包括公共频率资源和专用频率资源，公共频率资源上允许虚拟多入多出VMIMO配对，能够用于调度边缘UE和非边缘UE，专用频率资源上不允许VMIMO配对，只能用于调度边缘UE。
104，基站向UE发送调度信息，调度信息用于指示基站为UE调度的频率资源。
本发明实施例通过确定UE的调度类型为边缘UE或非边缘UE，根据UE的调度类型以及UE的服务小区的频率资源配置为UE调度资源，使得边缘UE优先在配置的专用频率资源上被调度，并且使得在专用频率资源上调度的边缘UE不进行VMIMO配对，从而能够在保证整个VMIMO系统吞吐量的情况下提升边缘UE的吞吐量和性能。
首先，UE可以通过向基站发送调度请求，来请求基站为其分配上行时频资源，以便于UE通过分配的上行时频资源向基站发送上行数据。具体地，该调度请求可以通过物理上行链路控制信道(Physicl Uplink Control Channel，PUCCH)、物理上行链路共享信道(Physicl Uplink Schared Channel，PUSCH)或者其他上行信道发送。调度请求可以携带有指示基站为该UE分配时频资源的消息字段，例如上行调度请求(Schduling Request，SR)，还可以是UE的无线接入请求消息，也可以是UE向基站发送的其他上行消息，本发明对此并不限定。
在接收到UE发送的调度请求后，基站可以确定UE的调度类型，即确定UE为边缘UE或非边缘UE。应理解，在移动通信网络中，一个小区可以同时为多个UE提供通信服务，可理解为服务小区可以控制多个UE。其中，边缘UE的判断标准可以基于UE的地理位置，例如位于的小区边缘的UE被认为是边缘UE。或者，边缘UE的判断标准也可以基于吞吐量，例如吞吐量最低的部分UE被认为是边缘UE。该吞吐量最低的部分UE可以是固定比例，例如5％，具体取值可以基于网络需求确定。
此外，基站也可以通过测量UE与基站之间的信道的信号干扰噪声比(Singal to Interference Noise Ratio，SINR)或UE上报的参考信号接收功率 (Reference Signal Receiving Power，RSRP)，或者通过UE上报的该UE与其服务小区和相邻小区的RSRP差或者SINR差来确定。
UE的服务小区的频率资源配置，用于指示该服务小区的频率资源包括专用频率资源和公共频率资源。该频率资源配置可以是由基站或者上层网元预先配置的，在基站或小区启动工作加入网络，或者调整设置后，在各个小区的控制单元生效。该频率资源配置也可以是由网络维护人员针对全网，或某些基站或某些小区设置的。本发明对此并不限定。
以UE的服务小区为例，根据频率资源配置，该服务小区的频率资源可以配置为公共频率资源和专用频率资源，其中专用频率资源为只用于调度边缘UE的专用频率资源，并且在专用频率资源上调度的边缘UE不进行VMIMO配对；公共频率资源为主要用于调度非边缘UE的公共频率资源，在专用频率资源占满的情况下，公共频率资源也可以用于调度边缘UE，公共频率资源上调度的非边缘UE可以进行VMIMO配对。
应理解，服务小区的频率资源(时频资源)的配置和分配事实上是针对时间和频率两个维度的，然而为了方便描述，时频资源的配置和分配只针对频率维度进行了叙述，本领域技术人员能够理解，在对时频资源进行配置时，如果以资源块(Resource Block，RB)为单位进行配置，则同时涉及时间和频率，本发明对于频率维度的叙述并不对此造成限定。
专用频率资源可以为一段连续的频率资源，优选地，位于UE的服务小区的频率资源的任意一端，或者位于整个频带的中部。可选地，专用频率资源也可以为多段不连续的频带资源，本发明对此并不限定。专用频率资源占用的频带宽度(资源块RB的个数)和在服务小区的频率资源上的位置，可以由基站或控制基站的上层网络设备预先配置，即频率资源配置。
频率资源的配置方式可以有以下几种，不仅仅针对UE的服务小区的频率资源配置方式，同时还可以针对通信系统中其他基站或小区的频率资源配置方式：
可选地，作为一个实施例，专用频率资源为UE的服务小区的频率资源中预先配置的一段连续频率，预先配置的一段连续频率包含UE的服务小区的频率资源中的最高频率或最低频率。
也就是说，专用频率资源，优选的可以集中配置在服务小区的频率资源的某一端。具体地，可以从整个频率资源的最小频率开始，向中间频带方向， 将一段连续的频带配置为专用频率资源，剩余部分则配置为公共频率资源。当然也可以从整个频率资源的最大频率开始。
这样的配置方式使得专用频率资源集中在整个频带的一端，与公共频率资源的频率交界较少，因而调度在专用频率资源上的边缘UE与调度在公共频率资源上的用户的隔离度较高，使得边缘UE受到的干扰尽可能减小，从而有助于提高边缘UE的吞吐量和性能。
可选地，还可以从服务小区的频率资源的中间频率开始，向频率资源的两端，将至少一段连续的频带确定为专用频率资源，并且将剩余频带确定为公共频率资源。也就是说，专用频率资源的配置，也可以从整个频率资源的中间频率开始向两端确定一定个数的RB配置为专用频率资源。整个频率资源两端的剩余部分则配置为公共频率资源。这样的配置方式使得专用频率资源集中在整个频带的中部，与公共频率资源的频率交界较少，因而调度在专用频率资源上的边缘UE与调度在公共频率资源上的用户的隔离度较高，使得边缘UE受到的干扰尽可能减小，从而有助于提高边缘UE的吞吐量和性能。
应理解，整个通信系统中可以包括不止一个小区，其中UE的服务小区的控制基站可以将其整个的频率资源配置为专用频率资源和公共频率资源，而与UE的服务小区相邻的第二小区的控制基站同样可以将第二小区整个的频率资源配置为专用频率资源和公共频率资源，其中第二小区与UE的服务小区的专用频率资源和公共频率资源的配置方式不同，即专用频率资源在频带错开。服务小区和第二小区的控制基站可以为同一基站，也可以为不同的基站。
其中，作为一个的实施例，使得相邻小区的专用频率资源错开程度最大化，服务小区可以由整个频率资源的最小频率开始，向整个频率资源的中部方向，将一定宽度的频带配置为专用频率资源；第二小区可以由整个频率资源的最大频率开始，向整个频率资源的中部方向，将一定宽度的频带配置为专用频率资源，反之亦然。
可选地，还可以有第三小区，第三小区为服务小区的相邻小区，第三小区的专用频率资源和公共频率资源的配置与服务小区的配置方式相同，即第三小区和服务小区的专用频率资源对齐。服务小区和第三小区的控制基站可以为同一基站，也可以为不同的基站。
对于多个相邻小区来说，如果相邻小区的频带配置方式相同，专用频率资源在整个频带上的位置对齐，并且在对齐的专用频率资源上边缘UE不进行VMIMO配对，边缘UE受到的干扰基本为单输入多输出SIMO干扰，相对高阶VMIMO配对带来的干扰大大降低，从而能够达到在不影响VMIMO系统容量情况下，提高边缘UE的吞吐量和性能的目的。
当整个系统中的相邻小区(同基站下的相邻小区，不同基站下的相邻小区)的频率资源的配置都相同，即所有相邻小区的专用频率资源都对齐时，由于专用频率资源与公共频率资源之间较高的隔离度，边缘UE受到调度在公共频率资源上的UE之间的干扰降低，因此边缘UE受到的干扰基本为SIMO干扰，降低了公共频率资源上高阶VMIMO配对带来的干扰，从而能够大大的提高边缘UE的吞吐量和性能，并且基本不影响整个系统的容量。
可选地，作为一个实施例，当服务小区与第二小区的控制基站可以为同一基站或者为不同基站时，可以表示整个VMIMO网络中任意两个相邻的小区的专用频率资源配置方式都不相同，即相邻小区的专用频率资源全部错开。对于相邻小区的专用频率资源全部错开的情况，如果当前小区(例如服务小区)的公共频率资源与相邻小区(例如第二小区)的专用频率资源重合，可以限制服务小区公共频率资源的该重合部分上VMIMO配对层数不超过M，例如M＝2。在服务小区的剩余公共频率资源上可以进行多层VMIMO配对。
可选地，作为另一个实施例，当服务小区与第二小区的控制基站为不同基站，并且服务小区与第三小区的控制基站为同一基站时，可以表示同一个基站控制的多个小区或扇区的专用频率资源配置方式相同，即专用频率资源站内对齐，不同基站控制的相邻小区专用频率资源配置方式不同，即专用频率资源站间错开。
可选地，作为一个实施例，基站根据UE的调度类型，以及UE的服务小区的频率资源配置，为UE调度频率资源，包括：当UE为非边缘UE时，只在公共频率资源上为UE调度频率资源。也就是说，当UE被基站确定的调度类型为非边缘UE时，调度信息指示的频率资源只包含公共频率资源中的部分或全部未调度资源。
当UE被确定为非边缘UE时，基站在公共频率资源上调度该UE，且只能在公共频率资源上调度该UE。具体地，基站可以将公共频率资源上的部 分或全部未调度资源分配给该UE。并且可以使其与其他在公共频率资源上进行调度的非边缘UE进行VMIMO配对，具体可以采用轮询(round-robin，RR)算法、比例公平(proportional fair，PF)算法、随机配对、最大化容量配对等算法对非边缘UE进行配对，本发明对此并不限定。基站为非边缘UE调度的资源可以通过调度信息向该UE下发。
可选地，作为一个实施例，基站根据UE的调度类型，以及UE的服务小区的频率资源配置，为UE调度频率资源，包括：当UE为边缘UE时，在公共频率资源和专用频率资源中，优先在专用频率资源上为UE调度频率资源。也就是说，当UE被基站确定的调度类型为边缘UE时，调度信息指示的频率资源只包含专用频率资源中的部分或全部未调度资源；或者，调度信息指示的频率资源包含专用频率资源中的全部未调度资源，以及公共频率资源中的部分或全部未调度资源。
当确定UE为边缘UE时，基站为其分配资源，如果专用频率资源中有未调度资源，则将未调度资源的部分或全部分配给该边缘UE。如果专用频率资源中没有未调度资源，即专用频率资源被全部占用，则可以从公共频率资源中为边缘UE分配资源。并且，针对在公共频率资源上调度边缘UE的情况，禁止为该边缘UE进行VMIMO配对。
可选地，作为一个实施例，优先在专用频率资源上为UE调度频率资源，包括：在专用频率资源的未调度频率资源中，优先选择与公共频率资源的频率间距最大的频率资源。也就是说，调度信息指示的频率资源只包含专用频率资源中的部分未调度资源时，调度信息指示的频率资源包含：专用频率资源的未调度频率资源中，与公共频率资源的频率间距最大的频率资源。
在调度边缘UE时，可以根据频带的配置方式为UE调度资源，以进一步确保边缘UE与非边缘UE在调度时的隔离度。具体地，当专用频率资源被配置在整个频带的最大频率的一端时，可以由专用频率资源的最大频率一端开始，为边缘UE分配RB，相应地，对于非边缘UE，可以从公共频率资源的最小频率一端开始，为非边缘UE分配RB。这样从专用频率资源和公共频率资源相距最远的两端开始分配RB的方式，能够最大化边缘UE和非边缘UE之间的隔离度，能够进一步降低边缘UE受到的干扰，从而进一步提升边缘UE的吞吐量和性能。
此外，在为边缘UE分配RB之前，可以先判断专用频率资源上是否还 有未被调度的RB。如果有未被调度的RB则优先在专用频率资源上调度该边缘UE，如果未被调度的RB数量小于边缘UE需要的RB数量，则可以跨过专用频率资源和公共频率资源的分界，将公共频率资源的RB分配给该边缘UE，以补足专用频率资源RB的不足。如果专用频率资源上的所有RB都被调用，则可以将公共频率资源的RB分配给该边缘UE。
可选地，在确定专用频率资源包含至少一个未被调度的资源块RB，并且专用频率资源包含整个频率资源的最小频率时，从专用频率资源的最小频率开始，向整个频率资源的中间频率的方向，将专用频率资源的RB分配给该UE；或者在确定专用频率资源的所有RB已被调度时，将公共频率资源的RB分配给该UE。
基站在调度边缘UE时，可以根据频带的配置方式为UE调度资源，以进一步确保边缘UE与非边缘UE在调度时的隔离度。具体地，当专用频率资源被配置在整个频带的最小频率的一端时，可以由专用频率资源的最小频率一端开始，为边缘UE分配RB，相应地，对于非边缘UE，可以从公共频率资源的最大频率一端开始，为非边缘UE分配RB。这样从专用频率资源和公共频率资源相距最远的两端开始分配RB的方式，能够最大化边缘UE和非边缘UE之间的隔离度，能够进一步降低边缘UE受到的干扰，从而进一步提升边缘UE的吞吐量和性能。
此外，在为边缘UE分配RB之前，可以先判断专用频率资源上是否还有未被调度的RB。如果有未被调度的RB则优先在专用频率资源上调度该边缘UE，如果未被调度的RB数量小于边缘UE需要的RB数量，则可以跨过专用频率资源和公共频率资源的分界，将公共频率资源的RB分配给该边缘UE，以补足专用频率资源RB的不足。如果专用频率资源上的所有RB都被调用，则可以将公共频率资源的RB分配给该边缘UE。
可选地，如果专用频率资源位于整个频带的中部，则基站在调度边缘UE时，可以从专用频率资源的任意位置开始为边缘UE分配RB，而基站在调度非边缘UE时，则优先从整个频带的两端，即公共频率资源的最大频率和最小频率两端开始为非边缘UE分配RB。
可选地，作为一个实施例，基站根据UE的调度类型，以及UE的服务小区的频率资源配置，为UE调度频率资源，包括：当UE为边缘UE时，在公共频率资源和专用频率资源的未调度资源中，优先选择信号干扰噪声比 SINR最大的频率资源。也就是说，当UE被基站确定的调度类型为边缘UE时，调度信息指示的频率资源包含：公共频率资源和专用频率资源的未调度资源中，信号干扰噪声比SINR最大的频率资源。
其中，基站可以在整个频率资源(专用频率资源和公共频率资源)中确定各个RB的SINR，根据该UE需要的RB个数N，从中选取SINR总和较大的N个RB分配给该UE，优选地，该N个RB为连续的RB。也就是说，生成的调度信息所指示的分配给该UE的频率资源为整个频率资源中SINR最大的频率资源。
根据SINR选取RB为边缘UE调度时，由于将较优的资源优先分配给通信质量和强壮度较差的边缘UE，可以进一步提高边缘UE的抗干扰能力，从而提高边缘UE的吞吐量和性能。
可选地，作为一个实施例，基站确定UE的调度类型，包括：接收UE发送的上行信号，并确定UE的信号干扰噪声比SINR；当UE的SINR小于第一预设阈值时，确定UE为边缘UE；当目标UE的SINR大于第一预设阈值时，确定UE为非边缘UE。
在确定UE是否为边缘UE时，优选地可以通过测量UE的SINR来进行判断。其中，UE可以向服务小区的控制基站发送上行接入请求信号或上行同步信号，以便于服务小区的控制基站根据上行接入请求信号或上行同步信号确定该UE的信干噪比SINR。具体地，基站可以预先设定第一阈值，SINR小于该第一阈值的UE则确定为边缘UE。
应理解，测量和判断UE是否为边缘UE的参数不限于SINR，还可以通过参考信号接收功率RSRP、参考信号接收强度RSRQ、接收信号强度指示RSSI、UE与基站之间的距离等能够指示UE通信质量的参数进行判断。相应地，第一阈值的设定，以及大小关系与判断结果的设置与参数类型的不同而变化。例如测量参数为RSRP时，当测量结果小于第一阈值时，确定UE为边缘UE，而测量结果大于第一阈值时，确定UE为非边缘UE。对于测量结果等于第一阈值的情况，可以通过预先设置将等于的情况划分到边缘UE或非边缘UE。此外，用于判断UE是否为边缘UE的参数也可以是上述任意几种参数的组合，本发明对此并不限定。
可选地，作为一个实施例，确定是否为边缘UE，包括：基站确定UE的调度类型，包括：接收UE发送的参考信号接收功率RSRP差值，RSRP 差值包括UE的服务小区的下行参考信号的接收功率，与UE的服务小区的相邻小区的下行参考信号的接收功率的差值；当RSRP差的绝对值小于第一预设阈值时，确定UE为边缘UE；当RSRP差的绝对值大于第一预设阈值时，确定UE为非边缘UE。
可选地，作为一个实施例，在该UE为边缘UE时，所述方法还包括：当所述UE的SINR或所述RSRP差的绝对值小于第二预设阈值时，所述基站确定所述UE为受保护UE；则所述基站根据所述UE的调度类型，以及所述UE的服务小区的频率资源配置，为所述UE调度频率资源，包括：当所述UE为受保护UE时，只在所述专用频率资源上为所述UE调度频率资源。
当确定该UE为边缘UE后，还可以进一步判断该该UE是否为需要保护的UE，具体地，可以通过测得的UE的SINR或者RSRP差与预设的第二阈值进行比较来判断。对于需要保护的UE来说，基站限制其不能进行VMIMO配对，且约束其分配的RB数不能大于专用频率资源的RB数。这样可以保证若需要保护的UE为第一个调度的边缘UE则该需要保护的UE可完全落在专用频率资源内，不受多流VMIMO干扰。
与判断该UE是否为边缘UE相类似，测量和判断UE是否为需要保护的UE的参数不限于SINR，还可以通过RSRP、RSRQ、RSSI、UE与基站之间的距离等能够指示UE通信质量的参数进行判断。相应地，第二阈值的设定，以及大小关系与判断结果的设置与参数类型的不同而变化。例如测量参数为RSRP时，当测量结果小于第二阈值时，确定UE为需要保护的用户，而测量结果大于第二阈值时，确定UE为非需要保护的用户。对于测量结果等于第二阈值的情况，可以通过预先设置将等于的情况划分到需要保护的用户或非需要保护的用户。此外，用于判断UE是否为需要保护的用户的参数也可以是上述任意几种参数的组合，本发明对此并不限定。此外，用于判断UE是否为边缘UE的参数和用于判断UE是否为需要保护的用户的参数类型可以相同也可以不同。
基站向UE发送调度信息，调度信息用于指示基站为UE调度的频率资源。具体地，调度信息可以携带有指示基站为该UE分配的时频资源的消息字段，用于指示上述各实施例中的基站为UE调度的频率资源。该调度信息可以通过物理下行链路控制信道(Physicl Downlink Control Channel，PDCCH)、物理下行链路共享信道(Physicl Downlink Schared Channel， PDSCH)或者其他下行信道发送，本发明对此并不限定。
本发明实施例通过对小区的整个频率资源进行频带配置，使得小区边缘的用户优先在配置的专用频率资源上被调度，并且使得在专用频率资源上调度的边缘UE不进行VMIMO配对，从而在保证整个VMIMO系统吞吐量的情况，降低了边缘UE受到的来自于本小区以及相邻小区的VMIMO配对用户的干扰，从而能够提升边缘UE的吞吐量和性能。并且，可以通过将专用频率资源集中配置在整个频带的一端，减少与公共频率资源的频率交界，进一步提高在专用频率资源上的边缘UE与调度在公共频率资源上的用户的隔离度，使得边缘UE受到的干扰尽可能减小，或者通过相邻小区采用不同的频带配置方式，使得专用频率资源在整个频带上的位置得以相互错开，相邻小区各自的边缘UE之间的干扰进一步减小，从而能够进一步提高边缘UE的吞吐量和性能。
图2是本发明一个实施例的资源调度的方法的流程图。图2的方法由用户设备UE执行。
201，用户设备UE向基站发送调度请求，基站为UE的服务小区的控制基站，UE被基站确定的调度类型为边缘UE或者非边缘UE，其中，UE的服务小区的频率资源配置包括公共频率资源和专用频率资源，公共频率资源上允许虚拟多入多出VMIMO配对，能够用于调度边缘UE和非边缘UE；专用频率资源上不允许VMIMO配对，只能用于调度边缘UE。
202，UE接收基站发送的调度信息，调度信息用于指示基站为UE调度的频率资源。
本发明实施例通过对小区的整个频率资源进行频带配置，使得小区边缘的用户优先在配置的专用频率资源上被调度，并且使得在专用频率资源上调度的边缘UE不进行VMIMO配对，从而在保证整个VMIMO系统吞吐量的情况，降低了边缘UE受到的来自于本小区以及相邻小区的VMIMO配对用户的干扰，从而能够提升边缘UE的吞吐量和性能。并且，可以通过将专用频率资源集中配置在整个频带的一端，减少与公共频率资源的频率交界，进一步提高在专用频率资源上的边缘UE与调度在公共频率资源上的用户的隔离度，使得边缘UE受到的干扰尽可能减小，或者通过相邻小区采用不同的频带配置方式，使得专用频率资源在整个频带上的位置得以相互错开，相邻小区各自的边缘UE之间的干扰进一步减小，从而能够进一步提高边缘UE 的吞吐量和性能。
图3是本发明一个实施例的资源调度的方法的交互图。
S301，UE向基站发送调度请求。
首先，UE在接入网络，或者需要发送上行数据，或者变更设置后，可以向基站发送调度请求，来请求基站为其分配上行时频资源，以便于UE通过分配的上行时频资源向基站发送上行数据。具体地，该调度请求可以通过PUCCH、PUSCH或者其他上行信道发送。调度请求可以携带有指示基站为该UE分配时频资源的消息字段，例如SR，还可以是UE的无线接入请求消息，也可以是UE向基站发送的其他上行消息，本发明对此并不限定。
S302，基站确定UE的调度类型。
在接收到UE发送的调度请求后，基站可以确定UE的调度类型，即确定UE为边缘UE或非边缘UE。
基站在确定UE为边缘UE或非边缘UE时，可以基于UE的地理位置、或者UE的吞吐量、或者UE与基站之间的信道质量等等。例如，基站可以通过测量UE与基站之间的SINR或UE上报的RSRP，或者通过UE上报的该UE与其服务小区和相邻小区的RSRP差或者SINR差来确定UE是否为边缘UE。测量和判断UE是否为边缘UE的参数不限于SINR、RSRP，还可以通过参考信号接收强度RSRQ、接收信号强度指示RSSI、UE与基站之间的距离等能够指示UE通信质量的参数进行判断。相应地，第一阈值的设定，以及大小关系与判断结果的设置与参数类型的不同而变化。例如测量参数为RSRP时，当测量结果小于第一阈值时，确定UE为边缘UE，而测量结果大于第一阈值时，确定UE为非边缘UE。对于测量结果等于第一阈值的情况，可以通过预先设置将等于的情况划分到边缘UE或非边缘UE。此外，用于判断UE是否为边缘UE的参数也可以是上述任意几种参数的组合。
此外，在边缘UE中可以有一部分收保护UE，可以通过设定第二预设阈值来区分受保护的UE。具体地，当确定该UE为边缘UE后，还可以进一步判断该该UE是否为需要保护的UE，具体地，可以通过测得的UE的SINR或者RSRP差与预设的第二阈值进行比较来判断。对于需要保护的UE来说，基站限制其不能进行VMIMO配对，且约束其分配的RB数不能大于专用频率资源的RB数。这样可以保证若需要保护的UE为第一个调度的边缘UE则该需要保护的UE可完全落在专用频率资源内，不受多流VMIMO干扰。 与判断该UE是否为边缘UE相类似，测量和判断UE是否为需要保护的UE的参数不限于SINR，还可以通过RSRP、RSRQ、RSSI、UE与基站之间的距离等能够指示UE通信质量的参数进行判断。相应地，第二阈值的设定，以及大小关系与判断结果的设置与参数类型的不同而变化。例如测量参数为RSRP时，当测量结果小于第二阈值时，确定UE为需要保护的用户，而测量结果大于第二阈值时，确定UE为非需要保护的用户。对于测量结果等于第二阈值的情况，可以通过预先设置将等于的情况划分到需要保护的用户或非需要保护的用户。此外，用于判断UE是否为需要保护的用户的参数也可以是上述任意几种参数的组合，本发明对此并不限定。此外，用于判断UE是否为边缘UE的参数和用于判断UE是否为需要保护的用户的参数类型可以相同也可以不同
S303，基站根据UE的调度类型和服务小区的频率资源配置确定调度信息。
基站在确定了UE是否为边缘UE后，则根据一定的规则为UE调度资源。当UE为边缘UE时，且专用频率资源上具有未被调度的资源时，基站优先将专用频率资源上的未调度资源分配给该边缘UE，然而当专用频率资源都被占满时，可以将公共频率资源的调度给该UE。当UE为非边缘UE时，只在公共频率资源上调度该UE。基站可以根据调度结果生成携带有指示基站为UE分配的视频资源的消息字段的调度信息。
S304，基站向UE发送调度信息。
调度信息可以通过PDCCH、PDSCH或者其他下行信道发送，本发明对此并不限定。
图4是本发明另一个实施例的频谱资源配置的示意图。图4中示出了三种优选的频谱资源配置方式：配置0、配置1和配置2。
图4中所示的频带，左端为较低频率，右端为较高频率。应理解，图中的频带配置仅为示例。
其中，配置0的配置方式为：从整个频率资源的最大频率开始，向整个频率资源的中间频率的方向，将至少一段连续的频带(nE个RB)确定为专用频率资源，即边缘UE专用频率资源；并且将剩余频带确定为公共频率资源，即公共频率资源。其中RB的个数nE可以由基站预先配置，或者由网络维护人员手动进行配置，本发明对此并不限定。
配置1的配置方式为：从整个频率资源的最小频率开始，向整个频率资源的中间频率的方向，将至少一段连续的频带(nE个RB)确定为专用频率资源，即边缘UE专用频率资源；并且将剩余频带确定为公共频率资源，即公共频率资源。
配置2的配置方式为：从整个频率资源的中间频率开始，向整个频率资源的两端，将至少一段连续的频带(nE个RB)确定为专用频率资源，并且将剩余频带确定为公共频率资源，即公共频率资源。
对于以上三种频带配置方式来说，专用频率资源被集中在整个频带的一端，与公共频率资源的频率交界较少，因而调度在专用频率资源上的边缘UE与调度在公共频率资源上的用户的隔离度较高，使得边缘UE受到的干扰尽可能减小，从而有助于提高边缘UE的吞吐量和性能。
具体在进行资源调度时，对于配置0来说，较优的方式为：由专用频率资源的最大频率一端，即最右端开始，为边缘UE分配RB，相应地，对于非边缘UE，可以从公共频率资源的最小频率一端，即最左端开始，为非边缘UE分配RB。这样从专用频率资源和公共频率资源相距最远的两端开始分配RB的方式，能够最大化边缘UE和非边缘UE之间的隔离度，能够进一步降低边缘UE受到的干扰。
对于配置1来说，较优的方式为：由专用频率资源的最小频率一端，即最左端开始，为边缘UE分配RB，相应地，对于非边缘UE，可以从公共频率资源的最大频率一端，即最右端开始，为非边缘UE分配RB。这样从专用频率资源和公共频率资源相距最远的两端开始分配RB的方式，能够最大化边缘UE和非边缘UE之间的隔离度，能够进一步降低边缘UE受到的干扰。
对于配置2来说，较优的方式为：由专用频率资源的中点或者任意一端开始，为边缘UE分配RB，对于非边缘UE，可以从公共频率资源的最大频率或最小频率一端，即最右端或最左端开始，为非边缘UE分配RB。这样从专用频率资源和公共频率资源相距最远的两端开始分配RB的方式，能够最大化边缘UE和非边缘UE之间的隔离度，能够进一步降低边缘UE受到的干扰。
应理解，对于整个VMIMO系统，所有的小区都可以采用相同的频带配置方式，即上述三种配置中的任意一种。这样，专用频率资源在整个频带上 的位置对齐，并且在对齐的专用频率资源上边缘UE不进行VMIMO配对，边缘UE收到的干扰基本为单输入多输出SIMO干扰，相对高阶VMIMO配对带来的干扰大大降低，从而能够达到在不影响VMIMO系统容量情况下，提高边缘UE的吞吐量和性能的目的。
除了所有小区专用频率资源全部对齐，还可以有以下几种配置方案。
图5是本发明另一个实施例的频谱资源配置的示意图。图5中，组合在一起的三个六边形可以表示一个基站控制的三个蜂窝小区，或者三个扇区，每个基站控制区域内的数字0、1、2可以对应于上述图4中的三种频带配置。可以看出，同一个基站控制的多个小区或扇区的专用频率资源配置方式相同，即专用频率资源站内对齐，不同基站控制的相邻小区专用频率资源配置方式不同，即专用频率资源站间错开。站内专用频率资源对齐可以减小站内干扰，站间专用频率资源错开可以减小站间干扰。
图6是本发明另一个实施例的频谱资源配置的示意图。与图5相类似，组合在一起的三个六边形可以表示一个基站控制的三个蜂窝小区，或者三个扇区，每个小区内的数字0、1、2可以对应于上述图4中的三种频带配置。可以看出，每两个相邻小区的频带配置都不相同，即所有小区的专用频率资源全部错开，那么相邻小区各自的边缘UE之间的干扰将会减小，从而能够进一步提高边缘UE的吞吐量和性能。
图7是本发明一个实施例的基站的示意框图。图6的基站60包括接收单元61、处理单元62和发送单元63。
接收单元61接收用户设备UE发送的调度请求。处理单元62确定UE的调度类型，调度类型为边缘UE或者非边缘UE。处理单元62根据UE的调度类型，以及UE的服务小区的频率资源配置，为UE调度频率资源，其中，UE的服务小区的频率资源配置包括公共频率资源和专用频率资源，公共频率资源上允许虚拟多入多出VMIMO配对，能够用于调度边缘UE和非边缘UE，专用频率资源上不允许VMIMO配对，只能用于调度边缘UE。发送单元63向UE发送调度信息，调度信息用于指示基站为UE调度的频率资源。
本发明实施例的基站60通过确定UE的调度类型为边缘UE或非边缘UE，根据UE的调度类型以及UE的服务小区的频率资源配置为UE调度资源，使得边缘UE优先在配置的专用频率资源上被调度，并且使得在专用频 率资源上调度的边缘UE不进行VMIMO配对，从而能够在保证整个VMIMO系统吞吐量的情况下提升边缘UE的吞吐量和性能。
首先，UE可以通过向基站60发送调度请求，来请求基站60为其分配上行时频资源，以便于UE通过分配的上行时频资源向基站60发送上行数据。具体地，该调度请求可以通过物理上行链路控制信道(Physicl Uplink Control Channel，PUCCH)、物理上行链路共享信道(Physicl Uplink Schared Channel，PUSCH)或者其他上行信道发送。调度请求可以携带有指示基站60为该UE分配时频资源的消息字段，例如上行调度请求(Schduling Request，SR)，还可以是UE的无线接入请求消息，也可以是UE向基站60发送的其他上行消息，本发明对此并不限定。
UE的服务小区的频率资源配置，用于指示该服务小区的频率资源配置为专用频率资源和公共频率资源。该频率资源配置可以是由基站60或者上层网元预先配置的，在基站60或小区启动工作加入网络，或者调整设置后，在各个小区的控制单元生效。该频率资源配置也可以是由网络维护人员针对全网，或某些基站60或某些小区设置的。本发明对此并不限定。
以UE的服务小区为例，根据频率资源配置，该服务小区的频率资源(频带)可以配置为公共频率资源和专用频率资源，其中专用频率资源为只用于调度边缘UE的专用频率资源，并且在专用频率资源上调度的边缘UE不进行VMIMO配对；公共频率资源为主要用于调度非边缘UE的公共频率资源，在专用频率资源占满的情况下，公共频率资源也可以用于调度边缘UE，公共频率资源上调度的非边缘UE可以进行VMIMO配对。
专用频率资源可以为一段连续的频率资源，优选地，位于UE的服务小区的频率资源的任意一端，或者位于整个频带的中部。可选地，专用频率资源也可以为多段不连续的频带资源，本发明对此并不限定。专用频率资源占用的频带宽度(资源块RB的个数)和在服务小区的频率资源上的位置，可以由基站60或控制基站60的上层网络设备预先配置，即频率资源配置。
可选地，作为一个实施例，专用频率资源为UE的服务小区的频率资源中预先配置的一段连续频率，预先配置的一段连续频率包含UE的服务小区的频率资源中的最高频率或最低频率。
也就是说，专用频率资源，优选的可以配置为从服务小区的频率资源的一端开始的一段频带。具体地，可以从整个频率资源的最小频率开始，向中 间频带方向，将一段连续的频带配置为专用频率资源，剩余部分则配置为公共频率资源。当然也可以从整个频率资源的最大频率开始。
这样的配置方式使得专用频率资源集中在整个频带的一端，与公共频率资源的频率交界较少，因而调度在专用频率资源上的边缘UE与调度在公共频率资源上的用户的隔离度较高，使得边缘UE受到的干扰尽可能减小，从而有助于提高边缘UE的吞吐量和性能。
可选地，还可以从服务小区的频率资源的中间频率开始，向频率资源的两端，将至少一段连续的频带确定为专用频率资源，并且将剩余频带确定为公共频率资源。也就是说专用频率资源的配置，也可以从整个频率资源的中间频率开始向两端确定一定个数的RB配置为专用频率资源。整个频率资源两端的剩余部分则配置为公共频率资源。这样的配置方式使得专用频率资源集中在整个频带的中部，与公共频率资源的频率交界较少，因而调度在专用频率资源上的边缘UE与调度在公共频率资源上的用户的隔离度较高，使得边缘UE受到的干扰尽可能减小，从而有助于提高边缘UE的吞吐量和性能。
对于多个相邻小区来说，如果相邻小区的频带配置方式不同，专用频率资源在整个频带上的位置得以相互错开，那么相邻小区各自的边缘UE之间的干扰将会减小，从而能够进一步提高边缘UE的吞吐量和性能。
对于多个相邻小区来说，如果相邻小区的频带配置方式相同，专用频率资源在整个频带上的位置对齐，并且在对齐的专用频率资源上边缘UE不进行VMIMO配对，边缘UE收到的干扰基本为单输入多输出SIMO干扰，相对高阶VMIMO配对带来的干扰大大降低，从而能够达到在不影响VMIMO系统容量情况下，提高边缘UE的吞吐量和性能的目的。
可选地，作为一个实施例，处理单元62具体用于：当UE为非边缘UE时，只在公共频率资源上为UE调度频率资源。也就是说，当UE被基站60确定的调度类型为非边缘UE时，调度信息指示的频率资源只包含公共频率资源中的部分或全部未调度资源。
当UE被确定为非边缘UE时，基站60在公共频率资源上调度该UE，且只能在公共频率资源上调度该UE。具体地，基站60可以将公共频率资源上的部分或全部未调度资源分配给该UE。并且可以使其与其他在公共频率资源上进行调度的非边缘UE进行VMIMO配对，具体可以采用轮询(round-robin，RR)算法、比例公平(proportional fair，PF)算法、随机配 对、最大化容量配对等算法对非边缘UE进行配对，本发明对此并不限定。基站60为非边缘UE调度的资源可以通过调度信息向该UE下发。
可选地，作为一个实施例，处理单元62具体用于：当UE为边缘UE时，在公共频率资源和专用频率资源中，优先在专用频率资源上为UE调度频率资源。也就是说，当UE被基站60确定的调度类型为边缘UE时，调度信息指示的频率资源只包含专用频率资源中的部分或全部未调度资源；或者，调度信息指示的频率资源包含专用频率资源中的全部未调度资源，以及公共频率资源中的部分或全部未调度资源。
当确定UE为边缘UE时，基站60为其分配资源，如果专用频率资源中有未调度资源，则将未调度资源的部分或全部分配给该边缘UE。如果专用频率资源中没有未调度资源，即专用频率资源被全部占用，则可以从公共频率资源中为边缘UE分配资源。并且，针对在公共频率资源上调度边缘UE的情况，禁止为该边缘UE进行VMIMO配对。
可选地，作为一个实施例，处理单元62具体用于：在专用频率资源的未调度频率资源中，优先选择与公共频率资源的频率间距最大的频率资源。也就是说，调度信息指示的频率资源只包含专用频率资源中的部分未调度资源时，调度信息指示的频率资源包含：专用频率资源的未调度频率资源中，与公共频率资源的频率间距最大的频率资源。
在调度边缘UE时，可以根据频带的配置方式为UE调度资源，以进一步确保边缘UE与非边缘UE在调度时的隔离度。具体地，当专用频率资源被配置在整个频带的最大频率的一端时，可以由专用频率资源的最大频率一端开始，为边缘UE分配RB，相应地，对于非边缘UE，可以从公共频率资源的最小频率一端开始，为非边缘UE分配RB。这样从专用频率资源和公共频率资源相距最远的两端开始分配RB的方式，能够最大化边缘UE和非边缘UE之间的隔离度，能够进一步降低边缘UE受到的干扰，从而进一步提升边缘UE的吞吐量和性能。
此外，在为边缘UE分配RB之前，可以先判断专用频率资源上是否还有未被调度的RB。如果有未被调度的RB则优先在专用频率资源上调度该边缘UE，如果未被调度的RB数量小于边缘UE需要的RB数量，则可以跨过专用频率资源和公共频率资源的分界，将公共频率资源的RB分配给该边缘UE，以补足专用频率资源RB的不足。如果专用频率资源上的所有RB都 被调用，则可以将公共频率资源的RB分配给该边缘UE。
可选地，在确定专用频率资源包含至少一个未被调度的资源块RB，并且专用频率资源包含整个频率资源的最小频率时，从专用频率资源的最小频率开始，向整个频率资源的中间频率的方向，将专用频率资源的RB分配给该UE；或者在确定专用频率资源的所有RB已被调度时，将公共频率资源的RB分配给该UE。
基站60在调度边缘UE时，可以根据频带的配置方式为UE调度资源，以进一步确保边缘UE与非边缘UE在调度时的隔离度。具体地，当专用频率资源被配置在整个频带的最小频率的一端时，可以由专用频率资源的最小频率一端开始，为边缘UE分配RB，相应地，对于非边缘UE，可以从公共频率资源的最大频率一端开始，为非边缘UE分配RB。这样从专用频率资源和公共频率资源相距最远的两端开始分配RB的方式，能够最大化边缘UE和非边缘UE之间的隔离度，能够进一步降低边缘UE受到的干扰，从而进一步提升边缘UE的吞吐量和性能。
可选地，如果专用频率资源位于整个频带的中部，则基站60在调度边缘UE时，可以从专用频率资源的任意位置开始为边缘UE分配RB，而基站60在调度非边缘UE时，则优先从整个频带的两端，即公共频率资源的最大频率和最小频率两端开始为非边缘UE分配RB。
可选地，作为一个实施例，处理单元62具体用于：当UE为边缘UE时，在公共频率资源和专用频率资源的未调度资源中，优先选择信号干扰噪声比SINR最大的频率资源。也就是说，当UE被基站60确定的调度类型为边缘UE时，调度信息指示的频率资源包含：公共频率资源和专用频率资源的未调度资源中，信号干扰噪声比SINR最大的频率资源。
其中，基站60可以在整个频率资源(专用频率资源和公共频率资源)中确定各个RB的SINR，根据该UE需要的RB个数N，从中选取SINR总和较大的N个RB分配给该UE，优选地，该N个RB为连续的RB。也就是说，生成的调度信息所指示的分配给该UE的频率资源为整个频率资源中SINR最大的频率资源。
根据SINR选取RB为边缘UE调度时，由于将较优的资源优先分配给通信质量和强壮度较差的边缘UE，可以进一步提高边缘UE的抗干扰能力，从而提高边缘UE的吞吐量和性能。
可选地，作为一个实施例，处理单元62具体用于：接收UE发送的上行信号，并确定UE的信号干扰噪声比SINR；当UE的SINR小于第一预设阈值时，确定UE为边缘UE；当目标UE的SINR大于第一预设阈值时，确定UE为非边缘UE。
在确定UE是否为边缘UE时，优选地可以通过测量UE的SINR来进行判断。其中，UE可以向服务小区的控制基站60发送上行接入请求信号或上行同步信号，以便于服务小区的控制基站60根据上行接入请求信号或上行同步信号确定该UE的信干噪比SINR。具体地，基站60可以预先设定第一阈值，SINR小于该第一阈值的UE则确定为边缘UE。
应理解，测量和判断UE是否为边缘UE的参数不限于SINR，还可以通过参考信号接收功率RSRP、参考信号接收强度RSRQ、接收信号强度指示RSSI、UE与基站60之间的距离等能够指示UE通信质量的参数进行判断。相应地，第一阈值的设定，以及大小关系与判断结果的设置与参数类型的不同而变化。例如测量参数为RSRP时，当测量结果小于第一阈值时，确定UE为边缘UE，而测量结果大于第一阈值时，确定UE为非边缘UE。对于测量结果等于第一阈值的情况，可以通过预先设置将等于的情况划分到边缘UE或非边缘UE。此外，用于判断UE是否为边缘UE的参数也可以是上述任意几种参数的组合，本发明对此并不限定。
可选地，作为一个实施例，处理单元62具体用于：通过接收单元接收UE发送的参考信号接收功率RSRP差值，RSRP差值包括UE的服务小区的下行参考信号的接收功率，与UE的服务小区的相邻小区的下行参考信号的接收功率的差值；当RSRP差的绝对值小于第一预设阈值时，确定UE为边缘UE；当RSRP差的绝对值大于第一预设阈值时，确定UE为非边缘UE。
可选地，作为一个实施例，处理单元62具体用于：当所述UE的SINR或所述RSRP差的绝对值小于第二预设阈值时，所述基站60确定所述UE为受保护UE；则所述基站60根据所述UE的调度类型，以及所述UE的服务小区的频率资源配置，为所述UE调度频率资源，包括：当所述UE为受保护UE时，只在所述专用频率资源上为所述UE调度频率资源。。
当确定该UE为边缘UE后，还可以进一步判断该该UE是否为需要保护的UE，具体地，可以通过测得的UE的SINR或者RSRP差与预设的第二阈值进行比较来判断。对于需要保护的UE来说，基站60限制其不能进行 VMIMO配对，且约束其分配的RB数不能大于专用频率资源的RB数。这样可以保证若需要保护的UE为第一个调度的边缘UE则该需要保护的UE可完全落在专用频率资源内，不受多流VMIMO干扰。
与判断该UE是否为边缘UE相类似，测量和判断UE是否为需要保护的UE的参数不限于SINR，还可以通过RSRP、RSRQ、RSSI、UE与基站60之间的距离等能够指示UE通信质量的参数进行判断。相应地，第二阈值的设定，以及大小关系与判断结果的设置与参数类型的不同而变化。例如测量参数为RSRP时，当测量结果小于第二阈值时，确定UE为需要保护的用户，而测量结果大于第二阈值时，确定UE为非需要保护的用户。对于测量结果等于第二阈值的情况，可以通过预先设置将等于的情况划分到需要保护的用户或非需要保护的用户。此外，用于判断UE是否为需要保护的用户的参数也可以是上述任意几种参数的组合，本发明对此并不限定。此外，用于判断UE是否为边缘UE的参数和用于判断UE是否为需要保护的用户的参数类型可以相同也可以不同。
本发明实施例的基站60通过对小区的整个频率资源进行频带配置，使得小区边缘的用户优先在配置的专用频率资源上被调度，并且使得在专用频率资源上调度的边缘UE不进行VMIMO配对，从而在保证整个VMIMO系统吞吐量的情况，降低了边缘UE受到的来自于本小区以及相邻小区的VMIMO配对用户的干扰，从而能够提升边缘UE的吞吐量和性能。并且，可以通过将专用频率资源集中配置在整个频带的一端，减少与公共频率资源的频率交界，进一步提高在专用频率资源上的边缘UE与调度在公共频率资源上的用户的隔离度，使得边缘UE受到的干扰尽可能减小，或者通过相邻小区采用不同的频带配置方式，使得专用频率资源在整个频带上的位置得以相互错开，相邻小区各自的边缘UE之间的干扰进一步减小，从而能够进一步提高边缘UE的吞吐量和性能。
图8是本发明一个实施例的用户设备的示意框图。图8的用户设备UE 70包括发送单元71、接收单元72。
发送单元71向基站发送调度请求，基站为UE的服务小区的控制基站，UE被基站确定的调度类型为边缘UE或者非边缘UE,其中，UE的服务小区的频率资源配置包括公共频率资源和专用频率资源，公共频率资源上允许虚拟多入多出VMIMO配对，能够用于调度边缘UE和非边缘UE,专用频率资 源上不允许VMIMO配对，只能用于调度边缘UE。接收单元72接收接收基站发送的调度信息，调度信息用于指示基站为UE调度的频率资源。
本发明实施例通过对小区的整个频率资源进行频带配置，使得小区边缘的用户优先在配置的专用频率资源上被调度，并且使得在专用频率资源上调度的边缘UE不进行VMIMO配对，从而在保证整个VMIMO系统吞吐量的情况，降低了边缘UE受到的来自于本小区以及相邻小区的VMIMO配对用户的干扰，从而能够提升边缘UE的吞吐量和性能。并且，可以通过将专用频率资源集中配置在整个频带的一端，减少与公共频率资源的频率交界，进一步提高在专用频率资源上的边缘UE与调度在公共频率资源上的用户的隔离度，使得边缘UE受到的干扰尽可能减小，或者通过相邻小区采用不同的频带配置方式，使得专用频率资源在整个频带上的位置得以相互错开，相邻小区各自的边缘UE之间的干扰进一步减小，从而能够进一步提高边缘UE的吞吐量和性能。
图9是本发明另一实施例的基站的示意框图。图9的基站80包括处理器81和存储器82。处理器81和存储器82通过总线系统83相连。
存储器82用于存储使得处理器81执行以下操作的指令：接收用户设备UE发送的调度请求；确定UE的调度类型，调度类型为边缘UE或者非边缘UE；根据UE的调度类型，以及UE的服务小区的频率资源配置，为UE调度频率资源；向UE发送调度信息，调度信息用于指示基站为UE调度的频率资源；其中，UE的服务小区的频率资源配置包括公共频率资源和专用频率资源；公共频率资源上允许虚拟多入多出VMIMO配对，能够用于调度边缘UE和非边缘UE；专用频率资源上不允许VMIMO配对，只能用于调度边缘UE。
本发明实施例的基站80通过确定UE的调度类型为边缘UE或非边缘UE，根据UE的调度类型以及UE的服务小区的频率资源配置为UE调度资源，使得边缘UE优先在配置的专用频率资源上被调度，并且使得在专用频率资源上调度的边缘UE不进行VMIMO配对，从而能够在保证整个VMIMO系统吞吐量的情况下提升边缘UE的吞吐量和性能。
此外，基站80还可以包括发射电路84、接收电路85及天线86等。处理器81控制基站80的操作，处理器81还可以称为CPU(Central Processing Unit，中央处理单元)。存储器82可以包括只读存储器和随机存取存储器， 并向处理器81提供指令和数据。存储器82的一部分还可以包括非易失性随机存取存储器(NVRAM)。具体的应用中，发射电路84和接收电路85可以耦合到天线86。基站80的各个组件通过总线系统83耦合在一起，其中总线系统83除包括数据总线之外，还可以包括电源总线、控制总线和状态信号总线等。但是为了清楚说明起见，在图中将各种总线都标为总线系统83。
上述本发明实施例揭示的方法可以应用于处理器81中，或者由处理器81实现。处理器81可能是一种集成电路芯片，具有信号的处理能力。在实现过程中，上述方法的各步骤可以通过处理器81中的硬件的集成逻辑电路或者软件形式的指令完成。上述的处理器81可以是通用处理器、数字信号处理器(DSP)、专用集成电路(ASIC)、现成可编程门阵列(FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。可以实现或者执行本发明实施例中的公开的各方法、步骤及逻辑框图。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。结合本发明实施例所公开的方法的步骤可以直接体现为硬件译码处理器执行完成，或者用译码处理器中的硬件及软件模块组合执行完成。软件模块可以位于随机存储器，闪存、只读存储器，可编程只读存储器或者电可擦写可编程存储器、寄存器等本领域成熟的存储介质中。该存储介质位于存储器82，处理器81读取存储器82中的信息，结合其硬件完成上述方法的步骤。
可选地，作为一个实施例，多个小区还包括第二小区，第二小区为服务小区的相邻小区，方法还包括：在第二小区的整个频率资源中确定第三频率资源和第四频率资源，其中第三频率资源上不允许UE进行VMIMO配对，第四频率资源上允许UE进行VMIMO配对，第三频率资源与专用频率资源不同，第四频率资源与公共频率资源不同。
