Description

一种应用于多系统的频谱调度方法及网络设备
本申请要求于2018年6月21日提交中国专利局、申请号为201810647316.8、申请名称为“一种应用于多系统的频谱调度方法及网络设备”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
本申请涉及通信领域，尤其涉及一种应用于多系统的频谱调度方法及网络设备。
背景技术
随着移动宽带经营(mobile broadband business，MBB)用户的快速发展，运营商持有的频谱也越来越紧缺，在有限的频谱内如何同时部署多个制式的系统是运营商面临的主要问题，例如，同时部署全球移动通信系统(global system for mobile communications，GSM)和通用移动通讯系统(universal mobile telecommunications system，UMTS)，或同时部署UMTS和长期演进(long term evolution，LTE)。应用在GSM/UMTS双模制式(GU)或UMTS/LTE双模制式(UL)时，对于下行方向，基站侧都可以通过网络侧的技术控制收发，对于上行方向，终端侧一直以协议定义的带宽进行信号发射。如图1A所示，在GU场景下，下行可以通过滤波技术解决GU之间的下行干扰；而上行方向，GU频谱交叠区域，GSM和UMTS上行均发射功率，造成GU之间存在严重的上行干扰。
现有方案中，分别提升各个系统的在干扰场景下的性能。例如，对于GU场景，在UMTS侧，采用基带窄带陷波技术，消除GSM强干扰，如图1B所示；并且在GSM侧，采用协作多点发送/接收(coordinated multipoint transmission/reception，CoMP)技术、多维度干扰抵消合并(multidimensional interference cancellation combining，MICC)技术等提升上行性能，如图1C所示。降低系统的接收总带宽功率(received total wide band power，RTWP)。
现有方案只能减少UMTS系统和其他制式系统间的干扰，但是无法彻底解决上行方向上的信号干扰问题。

具体实施方式
本申请实施例提供了一种应用于多系统的频谱调度方法及网络设备，用于消除多系统部署时上行方向上的信号干扰问题。
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例进行描述。
本申请文件中提及的“第一”或“第二”等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。此外，本申请文件中提及的“包括”或“具有”及其任何变形，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。
在多制式系统的部署场景中，由于频谱的宽度有限，不同制式的系统可能需要共用同一段频谱。例如，同时部署部署全球移动通信系统(global system for mobile communications，GSM)和通用移动通讯系统(universal mobile telecommunications system，UMTS)，即GU场景；或同时部署UMTS和长期演进(long term evolution，LTE)，即UL场景；或同时部署UMTS和UMTS，即UU场景；或同时部署UMTS和5G网络，即U&5G场景。不同的应用场景下，不同制式系统会产生干扰。
现有方案中，在UL场景下进行频谱共享时，如图2所示，频带共享时需要满足的条件为：UMTS除边带以外均不能落入LTE单边最小带宽内；LTE单边最小带宽不能落入UMTS下行核心带宽内。由于UMTS上行发射频谱可以限定在5MHz内，但是无法限定在更窄的带宽内，导致UL的整体共享带宽都受到了很大的限制。而下行方向，静态共享的方式导致频谱无法完全利用，边带0.6MHz，UMTS的发射功率相对较小，但对LTE的公共信道仍有干扰，对LTE而言性能仍有损失。现有方案中，只能减少UL系统间干扰，但是都无法彻底解决UMTS对LTE的上行方向上干扰问题。而在下行方向，UL静态共享的频谱利用率较低，灵活度也较差，无法真正发挥UL共享的价值。
为了解决多制式系统(例如，UMTS和其他相同或不同的系统)之间在上行方向上的信号干扰问题，本申请提供了一种应用于多系统的频谱调度方法，用于消除多系统部署时在上行方向上的信号干扰问题，同时提高在下行方向上的频谱共享的利用率。
本申请可以应用在上述多制式系统部署的场景中，例如，应用在GU场景；或应用在UL场景；或应用在UU场景；或应用在U&5G场景。为了简化过程，本申请仅以通过双载波高速下行分组接入(dual-cell high speed downlink packet access，DC-HSDPA)的调度方法解决在GU场景和UL场景下的上行干扰问题以及下行频谱共享问题为例，对GU和UL场景的过程进行详细描述，其他场景与GL场景和UL场景下的过程类似，此处不再赘述。
可以理解的是，对于LTE系统的载波聚合(carrier aggregation，CA)，或者是UMTS的双频段高速下行分组接入(dual-band high speed downlink packet access，DB-HSDPA)，原理上与本申请中DC-HSDPA的调度方法类似，可以实现跨频段的上行载波不发信号，解决上行干扰问题，具体此处不再赘述。
为便于理解，下面对本申请实施例的具体流程进行描述，请参阅图3，在GU场景下，本申请实施例中应用于多系统的频谱调度方法的一个实施例包括：
301、网络设备确定双载波高速下行分组接入DC-HSDPA的调度策略。
网络设备(例如，UMTS中的无线网络控制器(radio network controller，RNC)，或者LTE中的基站eNodeB等)确定双载波高速下行分组接入DC-HSDPA的调度策略，该调度策略用于禁止用户设备(user equipment，UE)在通用移动通讯系统UMTS的辅载波上发送上行信号。其中，调度策略可以通过配置实现，也可以通过预置的算法实现，具体此处不做限定。
需要说明的是，本申请中涉及的双载波高速下行分组接入DC-HSDPA，还包括了灵活的双载波高速下行分组接入flexible DC-HSDPA，具体此处不再赘述。
本申请中涉及到的网络设备可以是UMTS中的RNC，也可以是LTE中eNodeB，或者是5G系统中的gNodeB等，根据实际应用场景的不同，选择不同的设备，具体此处不做限定。
具体的，步骤301可以拆分为以下步骤：
301a、网络设备将辅载波的小区选择和重选参数设置为禁止驻留状态。
网络设备将辅载波的小区选择和重选参数SIB3和SIB4设置为禁止驻留状态。
其中，SIB3是用于UE在空闲态(Idle)模式下的小区重选参数。SIB4是用于UE在连 接态的小区重选参数。
具体的，网络设备将SIB3和SIB4中的小区接入限制参数(Cell Access Restriction)设置为禁止状态。为了实现将Cell Access Restriction设置为禁止状态，至少需要将Cell Access Restriction中的小区禁止标识(Cell Barred)和同频重选标识(Intra-frequency cell re-selection indicator)修改为禁止状态，即将Cell Barred的值设置为barred，将Intra-frequency cell re-selection indicator的值设置为not allowed；将小区禁止时长(Tbarred)修改为预置的最大时长，即将Tbarred的值设置为D1280。
需要说明的是，Cell Access Restriction中的参数设置，可以同时执行，也可以按照预置的顺序进行设置，具体此处不做限定。
步骤301b、网络设备将辅载波所在的小区设置为不能重选，和/或不能重定向，和/或不能切换。
网络设备在辅载波的配置信息中添加禁止标识，该禁止标识用于指示辅载波所在的小区不能被UE重选、不能被UE重定向。
需要说明的是，不能重选、不能重定向和不能切换等，可以同时设置，或选择部分进行设置，具体此处不做限定。
步骤301c、网络设备将辅载波所在的小区从异频切换邻区信息列表中删除。
网络设备将辅载波所在的小区从异频切换邻区信息列表中删除，该异频切换邻区信息列表包含于辅载波的配置信息中。
需要说明的是。步骤301a、301b和301c之间为并列关系，可以同时执行，也可以按照预置的顺序依次执行，具体此处不做限定。
302、网络设备将辅载波的公共信道的功率参数设置为最小值。
网络设备将辅载波的公共信道的功率参数设置为最小值。
具体的，网络设备可以将除导频信道之外的公共信道的功率参数设置为最小值。例如，物理共享信道(physical shared channel，PSCH)一般按照实际环境的测量结果来调整，使发射功率满足UE接收和调制的要求，本申请中网络设备可以将PSCH的功率参数PSCHPower的值调整为最小值-35，其中，物理共享信道又包含物理上行共享信道(physical uplink shared channel，PUSCH)和物理下行共享信道(physical downlink shared channel，PDSCH)，可以选择任意一个或全部进行设置。又例如，网络设备可以将辅助同步信道(secondary synchronization channel，SSCH)中的参数SSCHPower的值调整为最小值-35；网络设备可以将主公共控制物理信道(primary secondary common control physical channel，PCCPCH)的功率参数PCHPower的值调整为最小值-35；网络设备可以将辅助公共控制物理信道(secondary common control physical channel，SCCPCH)的功率参数PCHPower的值调整为最小值-35；网络设备可以将接入指示信道(access indicator channel，AICH)的功率参数AICHPowerOffset的值调整为最小值-22；网络设备可以将寻呼指示信道(paging indicator channel，PICH)的功率参数PICHPowerOffset的值调整为最小值-10；网络设备可以将广播信道(broadcasting  infomation channel，BCH)的功率参数BCHPower的值调整为最小值-35；网络设备可以将前向接入信道(forward access channel，FACH)的功率参数MaxFachPower的值调整为最小值-35。
需要说明的是，网络设备可以将上述将除导频信道之外的多个公共控制信道中的一个或多个信道的功率参数的值调整为最小值，具体此处不做限定。网络设备还可以通过调整公共信道的其他参数来减小功率，具体此处不做限定。
可以理解的是，步骤302为可选的，通过辅载波的公共信道按最小功率发射，将UMTS对其他系统的干扰降低到最小。
303、网络设备将调度策略和辅载波的公共信道的功率参数发送至用户设备。
网络设备将调度策略和辅载波的公共信道的功率参数发送至UE，以使得UE根据接收到的调度策略和辅载波的公共信道的功率参数进行通信，实现禁止用户设备使用UMTS辅载波的目的，实现UMTS辅载波无上行信号。
本申请实施例中，通过网络设备控制用户设备的驻留、重选、切换、重定向等方式，禁止普通用户使用辅载波，实现辅载波无上行信号，消除了多制式系统上行方向上的干扰问题。
请参阅图4，在UL场景下，本申请实施例中应用于多系统的频谱调度方法的另一个实施例包括：
401、网络设备获取每个发送时间间隔TTI的调度信息。
网络设备获取LTE系统中每个发送时间间隔(transmission time interval，TTI)的调度信息，此时网络设备为UMTS侧的设备。
需要说明的是，UMTS与LTE两各种制式系统在基站内或基站间支持TTI级别快速交互通道，支撑两个制式实时信息交互。
可以理解的，网络设备获取的TTI的调度信息，可以是跨系统，例如，UMTS侧的网络设备从LTE系统获取；也可以是同系统的，UMTS侧的网络设备从系统内部获取，具体此处不做限定。
402、网络设备根据调度信息确定频谱分配模式。
网络设备根据每个TTI的调度信息，确定UL的频谱分配模式，频谱分配模式为频分+时分模式。根据预先设定的优先原则，控制下行频谱的分配。在UMTS系统优先场景下：该场景下优先保证UMTS体验，当UMTS存在高数传需求，则UMTS侧的无线网络控制器RNC通知LTE侧基站eNodeB共享频谱需要始终占用，LTE不可以占用该频谱；当UMTS不存在高数传需求时，UMTS侧RNC通知LTE侧的eNodeB共享频谱处于可用状态，在此状态下，LTE侧的eNodeB可使用LTE优先模式，按需占用频谱。
可以理解的是，频谱分配模式除了由RNC来控制，还可以由eNodeB进行控制，具体的，在LTE优先场景下：该场景下优先保证LTE体验，当LTE存在高数传需求，并需要占用共享频谱，则在LTE侧的eNodeB通过快速交互通道，通知UMTS侧的NodeB针对共享频谱进行滤波；当LTE数传需求比较低或无数传需求，不需要占用共享频谱，则LTE侧的eNodeB通过快速通道，通知UMTS侧的NodeB针对共享频谱不进行滤波。在通过eNodeB和 NodeB直接进行频谱共享分配时，RNC需要将设置好的配置信息发送至eNodeB和NodeB，具体此处不做限定。
需要说明的是，UMTS与LTE通道间的时延跟系统负载有一定相关性，当系统负载较低时，两个制式的端到端交互时延较小，可以达成实时信息交互；当系统负载较高时，两个制式的端到端交互时延大，无法达成实时信息交互。因此需要解决高交互时延下的频谱利用率损失问题。当高交互时延场景下，当某个制式需要使用频谱时，需要等待另一个制式让出频谱后，本制式才可使用该共享频谱，必然引入频谱资源使用不及时的问题。本申请引入了小区频谱资源占用预测算法，根据小区内所有用户的缓存信息，以及信道信息，具体可以包括信道质量信息(channel quality indicator，CQI)、秩指示(rank indication，RI)和调制编码组合(modulation and coding set，MCS)等，提前预估制式内需要使用频谱的时刻，从而提前通知另一个制式释放频谱，克服通道时延过长带来的频谱利用率下降的问题，小区频谱资源占用预测算法为现有技术，具体此处不再赘述。
403、网络设备将辅载波的公共信道的功率参数设置为最小值。
网络设备将辅载波的公共信道的功率参数设置为最小值。
步骤403与步骤302类似，此处不再赘述。
需要说明的是，步骤403还可以在步骤401之前；或者，还可以在步骤401之后，且在步骤402之前，具体此处不做限定。
404、网络设备将辅载波的公共信道的功率参数和频谱分配模式发送至用户设备。
网络设备将辅载波的公共信道的功率参数和频谱分配模式发送至用户设备，以使得用户设备根据接收到的辅载波的公共信道的功率参数和频谱分配模式进行通信，实现禁止用户设备使用UMTS辅载波的目的，实现UMTS辅载波无上行信号，实现下行方向频谱的共享，提高了下行方向上的频谱效率。确保LTE优先模式场景下，LTE侧有数传需求，可随时占用共享频谱，UMTS优先模式场景下，优先保证UMTS自身系统性能，当UMTS需求较少时，LTE可占用共享频谱，提高了下行方向上频谱效率。
本申请实施例中，根据确定的频谱分配模式，在双载波高速下行分组接入部署中实现了辅载波所在频谱下行方向上的频谱共享，提高了频谱的利用率，提高了系统的整体性能。
需要说明的是，本申请实施例还除了应用GU场景、UL场景，正在可以应用在其他场景，例如，UU场景、U&5G场景等，不同的应用场景下的频谱情况也不同。具体的，在GU场景中，UMTS辅载波上行不发射功率，UMTS辅载波下行与GSM完全交叠，如图5A所示；在UU场景中，UMTS辅载波上行不发射功率，UMTS辅载波下行与主载波完全不交叠，如图5B所示；在UL场景中，UMTS辅载波上行不发射功率，UMTS辅载波下行与LTE进行时分+频分的共享，如图5C所示；在U&5G场景中，UMTS辅载波不发上行，UMTS辅载波作为5G上下行分离的上行频段，辅载波独享下行频谱，如图5D所示。
