Description

客户前置装置 技术领域
本发明涉及下一代移动通信系统中的客户前置装置和用于该客户前置装置的通信方法。
背景技术
目前,期待一种用于高空平台站(HAPS:High Altitude Platform Station)的客户前置装置(CPE:Customer Premises Equipment),该高空平台站利用卫星(例如,高轨卫星、中轨卫星、低轨卫星)而与地面的用户进行通信。该高空平台站也可以经由地面网关(Gateway)而与地面的用户进行通信。在日本,更加关注距离地面大约20公里左右的高度上的HAPS,通过该HAPS给地面的用户提供通信业务。
具体来说,如图1所示,HAPS经由上述CPE而给地面的用户提供通信服务。
由于HAPS通常会有很宽的区域覆盖范围,例如几百平方公里,然而对于该区域内的地面的用户来说,与他们相关的业务量实际上在空间域和时间域上有很大的动态性,也就是说,可能在某个时间点、某个区域的业务量较大,然而在下个时间点、另一区域的业务量比较大。
此外,HAPS和CPE之间的通信有可能干扰地面蜂窝基站与用户终端之间的通信。
面对上述情况,现有技术中处于开启状态(On State)的客户前置装置存在功耗较高,资源利用率较低的问题,并且有可能对其他装置产生干扰。

具体实施方式
为了使得本公开的目的、技术方案和优点更为明显,下面将参照附图详细描述根据本公开的示例实施例。在附图中,相同的参考标号自始至终表示相同的元件。应当理解:这里描述的实施例仅仅是说明性的,而不应被解释为限制本公开的范围。此外,这里所述的终端可以包括各种类型的终端,例如车辆终端、用户终端(User Equipment,UE)、移动终端(或称为移动台)或者固定终端。这里所述的基站包含eNB、gNB等。此外,这里所述的客户前置装置(CPE:Customer Premises Equipment)也可以作为分布式单元(DU:Distributed Unit)而被配置。此外,这里所述的高空平台站(HAPS:High Altitude Platform Station)也可以作为中心式单元(CU:Central Unit)而被配置。此外,中心式单元(CU)也可以被称为高空平台站的CU。分布式单元(DU)也可以被称为客户前置装置的DU。高空平台站也可以作为宿主DU(Donor-DU)而被配置。宿主DU(Donor-DU)也可以被称为高空平台站的宿主DU。
根据本发明的一个示例,可以定义客户前置装置的四种状态。
对于客户前置装置,定义了四种状态:开启状态(on)、空闲状态(idle)、半休眠状态(semi-off)、全休眠状态(off)。每一个客户前置装置支持这四种状态的全部或者一部分状态。
参照图2来说明根据本公开的一个实施例的客户前置装置(CPE:Customer premises equipment)。图2是本公开的实施例的客户前置装置的示意图。如图2所示,客户前置装置200具备接收单元210、发送单元220以及控制单元230。接收单元210接收业务量负载信息和配置信息中的至少一个,控制单元230根据接收到的业务量负载信息和配置信息中的至少一个来确定客户前置装置200进入开启状态或非开启状态,所述非开启状态至少包括休眠状态。所述非开启状态也可以包括空闲状态。
业务量负载(traffic load)信息可以由用户终端发送给客户前置装置,该业务量负载(traffic load)信息可以表示用户终端当前时刻的瞬时业务量负载,也可以表示特定的时刻的业务量负载,也可以表示特定期间内的业务量负载的累计或者平均值,如从当前的时刻起之后一段时间内的业务量负载累计或者平均值,也可以表示未来特定的时刻的预测的业务量负载,还可以表示未来特定期间内的预测的业务量负载的累计或者平均值,但本发明并不限定于上述形式。用户终端可以通过各种公知的方法来计算、估计、或预测上述业务量负载,也可以从其他设备来获得用户终端的业务量负载。
配置信息可以由高空平台站发送给客户前置装置。该配置信息可以用于指示客户前置装置进入开启状态或非开启状态,所述非开启状态至少包括休眠状态。所述非开启状态也可以包括空闲状态。配置信息也可以基于业务量负载而被确定。
可替换地,客户前置装置200也可以接收其他信息,并基于该信息而确定客户前置装置进入开启状态或非开启状态,所述非开启状态至少包括休眠状态。所述非开启状态也可以包括空闲状态。可替换地,客户前置装置200也可以根据预先被设定的准则(criteria)而确定客户前置装置进入开启状态或非开启状态,所述非开启状态至少包括休眠状态。所述非开启状态也可以包括空闲状态。预先被设定的准则(criteria)可以与上述用户终端的业务量负载信息或配置信息有关,但并不限定于此,也可以是与客户前置装置的实现有关的其他信息。
根据本公开的另一实施例的客户前置装置,在休眠状态下,当关于所述客户前置装置的条件被满足时,控制单元230确定客户前置装置200转换到与休眠状态不同的其他状态。
上述其他状态可以是上文中提到的开启状态、空闲状态的一方,也可以是客户前置装置的其他状态。
关于所述客户前置装置的条件可以是,客户前置装置可以设定定时器,若该定时器期满,则表示关于所述客户前置装置的条件被满足。
关于所述客户前置装置的条件也可以是,客户前置装置设定特定阈值,若从用户终端发送而来的业务量负载大于或等于该特定阈值,则表示关于所述客户前置装置的条件被满足。当然,关于所述客户前置装置的条件也可以是,从用户终端发送而来的业务量负载与该特定阈值相比的其他关系。对定时器或者阈值等的设定可以是客户前置装置自行设定的,也可以是客户前置装置基于上位站的(如,高空平台站)的指示而设定的。
根据本公开的另一实施例的客户前置装置,接收单元还被配置为从高空平台站接收配置信息,以及所述控制单元还被配置为在休眠状态下根据配置信息确定客户前置装置转换到与所述休眠状态不同的其他状态。
该配置信息也可以用于指示客户前置装置进入开启状态、空闲状态、或与休眠状态不同的其他状态。
此外,接收单元210也可以经由DCI、RRC或MAC CE通过新的信令来接收从高空平台站发来的配置信息,或者通过F1-AP信令来接收从高空平台站发来的配置信息。也可以是,配置信息从作为CU或者宿主DU(Donor-DU)的高空平台站被发送到客户前置装置的移动终端(MT:Mobile Terminal)功能模块。也可以是,配置信息从作为CU的高空平台站被发送到作为DU的客户前置装置。接收单元210也可以通过其他信道和其他信令来接收从高空平台站发来的配置信息。
根据本公开的另一实施例的客户前置装置,休眠状态包括全休眠状态,控制单元在全休眠状态下仅用于确定客户前置装置转换到与全休眠状态不同的其他状态。
具体来说,在全休眠状态下,客户前置装置也可以关闭全部DU功能、全部与用户终端进行发送和接收的功能,即关闭包括PDSCH(物理下行链路共享信道(PDSCH:Physical Downlink Shared Channel))、PDCCH(物理下行链路控制信道(Physical Downlink Control Channel))、PUSCH(物 理上行链路共享信道(Physical Uplink Shared Channel))、PUCCH(物理上行链路控制信道(Physical Uplink Control Channel))、PRACH(物理随机接入信道(Physical Random Access Channel))、其他信道在内的、与用户终端之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB(同步信号块(Synchronization Signal Block))、CSI-RS(信道状态信息参考信号(Channel State Information-Reference Signal))、SRS(探测参考信号(Sounding Reference Signal))、其他参考信道在内的与用户终端之间的上下行参考信号的发送和接收。
可替代地,在全休眠状态下,客户前置装置也可以在关闭上述功能的基础上,关闭全部MT功能、全部与CU或宿主DU(Donor-DU)之间进行发送和接收的功能,即关闭包括PDSCH、PDCCH、PUSCH、PUCCH、PRACH、其他信道在内的、与CU或宿主DU(Donor-DU)之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB、CSI-RS、SRS、其他参考信道在内的与CU或宿主DU(Donor-DU)之间的上下行参考信号的发送和接收。
也就是说,在全休眠状态下,至少客户前置装置的DU的功能全部被关闭,客户前置装置无法与用户终端进行通信,客户前置装置也就不能接收来自用户终端自行发送的信息(如调度请求),进而也就无法基于来自用户终端自行发送的信息而做出相应的反馈。
进一步,对全休眠状态的情况下客户前置装置的通信过程进行说明。
参考图4,针对处于全休眠状态下的客户前置装置自身确定转换到与全休眠状态不同的其他状态的情况进行说明。
在图4中举出转换到与全休眠状态不同的开启状态的例子,但也可以转换到与全休眠状态不同的其他状态。
在S401中,如上所述,客户前置装置的控制单元230可以根据接收到的业务量负载信息和配置信息中的至少一个而确定客户前置装置进入全休眠状态。
在S402中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置中的MT功能向CU或宿主DU报告)客户前置装置进入全休眠状态、或者仅报告全休眠状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从 DU向CU报告)客户前置装置进入全休眠状态、或者仅报告全休眠状态。
该报告的定时可以是在客户前置装置进入到全休眠状态之前。也就是说,客户前置装置可以在发送该报告后进入全休眠状态,或者,客户也可以在发送该报告给高空平台站,并接收到高空平台站的确认信息后,进入全休眠状态。
该报告的定时也可以是在客户前置装置进入到全休眠状态之后。在该情况下,客户前置装置在全休眠状态下仍然具有发送该报告给高空平台站的功能。
在S403中,客户前置装置也可以在关于客户前置装置的条件(如定时器期满)被满足时,确定转移到与全休眠状态不同的其他状态,例如开启状态。
在S404中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置中的MT功能向CU或宿主DU报告)客户前置装置转移到该其他状态、或者仅报告该其他状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从DU向CU报告)客户前置装置转移到该其他状态、或者仅报告该其他状态。
该报告的定时可以是在客户前置装置进入到所转移的该其他状态之前。也就是说,客户前置装置可以在发送该报告后进入到所转移的该状态,或者,客户前置装置也可以在发送该报告给高空平台站,并接收到高空平台站的确认信息后,进入到所转移的该状态。
该报告的定时也可以是在客户前置装置进入到所转移的该状态之后。即,在客户前置装置进入到所转移的该状态之后,该客户前置装置向高空平台站发送该报告。在该情况下,客户前置装置在该其他状态下仍然具有发送该报告给高空平台站的功能。
另外,参考图5,针对处于全休眠状态下的客户前置装置基于高空平台站发来的配置信息确定转换到与全休眠状态不同的其他状态的情况进行说明。
在图5中举出转换到与全休眠状态不同的开启状态的例子,但也可以转换到与全休眠状态不同的其他状态。
在S501中,高空平台站的控制单元330可以确定客户前置装置进入全休眠状态。
在S502中,高空平台站可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入全休眠状态的配置信息、或者高空平台站也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU发送)用于指示客户前置装置进入全休眠状态的配置信息。客户前置装置在接收到该配置信息后,根据该配置信息而确定进入全休眠状态。之后,客户前置装置进入全休眠状态。
在S503中,高空平台站的控制单元330也可以确定客户前置装置进入与全休眠状态不同的其他状态,例如开启状态。
在S504中,高空平台站可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入与全休眠状态不同的其他状态的配置信息、或者高空平台站也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU发送)用于指示客户前置装置进入与全休眠状态不同的其他状态的配置信息。客户前置装置在接收到该配置信息后,根据该配置信息而确定进入与全休眠状态不同的其他状态。之后,客户前置装置进入与全休眠状态不同的其他状态。
如上,说明了客户前置装置基于业务量负载信息或配置信息的至少一个而确定进入全休眠状态,并且,在客户前置装置处于全休眠状态的情况下,客户前置装置自身确定从全休眠状态脱离而进入与全休眠状态不同的其他状态的过程,也说明了客户前置装置基于从高空平台站发送的配置信息而确定从全休眠状态脱离而进入与全休眠状态不同的其他状态的过程。
客户前置装置处于全休眠状态的情况下,客户前置装置关闭全部DU功能、全部与用户终端之间进行发送和接收的通信功能,即关闭包括PDSCH、PDCCH、PUSCH、PUCCH、PRACH、其他信道在内的、与用户终端之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB、CSI-RS、SRS、其他参考信道在内的与用户终端之间的上下行参考信号的发送和接收。
可替代地,客户前置装置处于全休眠状态的情况下,客户前置装置关闭全部DU功能、全部与用户终端之间进行发送和接收的通信功能,即关闭包括PDSCH、PDCCH、PUSCH、PUCCH、PRACH、其他信道在内的、与用户 终端之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB、CSI-RS、SRS、其他参考信道在内的、与用户终端之间的上下行参考信号的发送和接收,在这个基础上,客户前置装置还关闭全部MT功能、全部与CU和宿主DU之间的发送和接收的功能,即关闭包括PDSCH、PDCCH、PUSCH、PUCCH、PRACH、其他信道在内的、与CU和宿主DU之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB、CSI-RS、SRS、其他参考信道在内的与CU和宿主DU之间的上下行参考信号的发送和接收。
因此,通过使客户前置装置进入全休眠状态,使得客户前置装置的上述功能被关闭,用于该客户前置装置的频率资源可以被用于其他客户前置装置,能够增加资源利用率,并且,也能够降低功耗。此外,由于客户前置装置的上述功能被关闭,也能够减小对其他客户前置装置的通信干扰。
根据本公开的另一实施例的客户前置装置,休眠状态包括半休眠状态,客户前置装置200还包括发送单元220,该发送单元被配置为在半休眠状态下,以预定时间间隔发送用于检测业务量负载的参考信号。
具体来说,在半休眠状态下,与全休眠状态相比,客户前置装置的发送单元能够以预定时间间隔发送用于检测业务量负载的参考信号。而在全休眠状态下,客户前置装置的发送单元无法发送用于检测业务量负载的参考信号。
进一步,对半休眠状态的情况下客户前置装置的通信过程进行说明。
参考图6,针对处于半休眠状态下的客户前置装置自身确定转换到与半休眠状态不同的其他状态的情况进行说明。
在图6中举出转换到与半休眠状态不同的开启状态的例子,但也可以转换到与半休眠状态不同的其他状态。
在S601中,如上所述,客户前置装置的发送单元220也可以向用户终端以预定时间间隔发送用于检测业务量负载的参考信号。
上述预定时间间隔可以由高空平台站而设置、也可以由高空平台站预先设定。
进一步,该参考信号也可以不同于与3GPP版本15、16、17中的参考信号。该参考信号也可以是SSB,该情况下发送该SSB的预定时间间隔也可以大于3GPP版本15、16、17中规定的最大时间间隔,即也可以大于最大周期。
可替换地,该参考信号也可以是SSB,并以周期5ms、10ms、20ms、40ms、80ms、160ms进行发送,该发送的周期也可以大于上述周期,例如是320ms,还可以以更长的周期进行发送。
在S602中,用户终端接收到用于检测业务量负载的参考信号后,估计业务量负载。如上所述,业务量负载可以是瞬时的、也可以是一段期间内的累计值或者平均值等,本发明并不对此进行限定。该业务量负载也可以是基于参考信号而做出的。
在S603中,若用户终端估计出的业务量负载是低业务量负载,则将表示该低业务量负载的业务量负载信息反馈给客户前置装置。
在S604中,客户前置装置根据所接收到的业务量负载信息而确定客户前置装置进入半休眠状态。
具体来说,客户前置装置200的控制单元230也可以在业务量负载信息低于特定阈值的情况下,确定客户前置装置200进入半休眠状态。该特定阈值可以是客户前置装置设定的,也可以基于高空平台站通知的信息而被设定的。显然,本发明并非仅限定为客户前置装置200的控制单元230仅在业务量负载信息小于特定阈值的的情况下,确定客户前置装置200进入半休眠状态,客户前置装置200的控制单元230也可以在业务量负载信息相比于特定阈值的其他情况下,确定客户前置装置200进入半休眠状态。
在S605中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置中的MT功能向CU或宿主DU报告)客户前置装置进入半休眠状态、或者仅报告半休眠状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从DU向CU报告)客户前置装置进入半休眠状态、或者仅报告半休眠状态。
该报告的定时可以是在客户前置装置进入到半休眠状态之前。也就是说,客户前置装置可以在发送该报告后进入半休眠状态,或者,客户也可以在发送该报告给高空平台站,并接收到高空平台站的确认信息后,进入半休眠状态。
该报告的定时也可以是在客户前置装置进入到半休眠状态之后。在该情况下,客户前置装置在半休眠状态下仍然具有发送该报告给高空平台站的功能。
在S606中,由于客户前置装置以预定时间间隔发送用于检测业务量负载 的参考信号,因此,客户前置装置以预定时间间隔向用户终端发送下一个用于检测业务量负载的参考信号。
在S607中,同S602步骤,用户终端接收到用于检测业务量负载的参考信号后,估计业务量负载。
在S608中,若用户终端估计出的业务量负载是高业务量负载,则将表示该高业务量负载的业务量负载信息反馈给客户前置装置。
在S609中,客户前置装置根据所接收到的业务量负载信息而确定客户前置装置进入开启状态。
具体来说,客户前置装置200的控制单元230也可以在业务量负载信息高于特定阈值的情况下,确定客户前置装置200进入开启状态。该特定阈值可以是客户前置装置设定的,也可以基于高空平台站通知的信息而被设定的。显然,本发明并非仅限定为客户前置装置200的控制单元230仅在业务量负载信息高于特定阈值的的情况下,确定客户前置装置200进入开启状态,客户前置装置200的控制单元230也可以在业务量负载信息相比于特定阈值的其他情况下,确定客户前置装置200进入开启状态。
在S610中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置中的MT功能向CU或宿主DU报告)客户前置装置进入开启状态、或者仅报告开启状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从DU向CU报告)客户前置装置进入开启状态、或者仅报告开启状态。
该报告的定时可以是在客户前置装置进入到开启状态之前。也就是说,客户前置装置可以在发送该报告后进入开启状态,或者,客户也可以在发送该报告给高空平台站,并接收到高空平台站的确认信息后,进入开启状态。
该报告的定时也可以是在客户前置装置进入到开启状态之后。
此外,在S609中说明的是,客户前置装置根据所接收到的业务量负载信息而确定客户前置装置进入开启状态。然而,客户前置装置也可以根据所接收到的业务量负载信息而确定客户前置装置进入与半休眠状态不同的其他状态。即,客户前置装置也可以根据所接收到的业务量负载信息而确定客户前置装置脱离半休眠状态。
在该情况下,如上所述,在S610中,客户前置装置也可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置 中的MT功能向CU或宿主DU报告)客户前置装置进入与半休眠状态不同的其他状态、或者仅报告该其他状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从DU向CU报告)客户前置装置进入与半休眠状态不同的其他状态、或者仅报告该其他状态。
接下来,参考图7,针对处于半休眠状态下的客户前置装置基于高空平台站发来的配置信息确定转换到与半休眠状态不同的其他状态的情况进行说明。为了便于阅读,对与图6相同的步骤简略地进行说明。
在图7中举出转换到与半休眠状态不同的开启状态的例子,但也可以转换到与半休眠状态不同的其他状态。
在S701中,同S601,客户前置装置的发送单元220也可以向用户终端以预定时间间隔发送用于检测业务量负载的参考信号。
在S702中,用户终端接收到用于检测业务量负载的参考信号后,估计业务量负载。
在S703中,若用户终端估计出的业务量负载是低业务量负载,则将表示该低业务量负载的业务量负载信息反馈给客户前置装置。
在S704中,客户前置装置根据所接收到的业务量负载信息而向高空平台站发送业务量负载报告。该业务量负载报告也可以表示客户前置装置所接收到的业务量负载信息。
在S704中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU发送(即,从客户前置装置中的MT功能向CU或宿主DU报告)业务量负载报告、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU发送(即,从DU向CU报告)业务量负载报告。
在S705中,高空平台站确定客户前置装置进入半休眠状态。
在S706中,高空平台站中的CU可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置指示(即,从CU或宿主DU向客户前置装置中的MT功能通知)客户前置装置进入半休眠状态、或仅通知半休眠状态,高空平台站中的CU也可以通过F1-AP信令向客户前置装置指示(即,从CU向DU通知)客户前置装置进入半休眠状态、或仅通知半休眠状态。客户前置装置基于进入半休眠状态的该指示或所通知的该半休眠状态而进入半休眠状态。
在S707中,由于客户前置装置在半休眠状态下以预定时间间隔发送用于 检测业务量负载的参考信号,因此,处于半休眠状态下的客户前置装置以预定时间间隔向用户终端发送下一个用于检测业务量负载的参考信号。
在S708中,同S702步骤,用户终端接收到用于检测业务量负载的参考信号后,估计业务量负载。
在S709中,若用户终端估计出的业务量负载是高业务量负载,则将表示该高业务量负载的业务量负载信息反馈给客户前置装置。
在S710中,客户前置装置根据所接收到的业务量负载信息而向高空平台站发送业务量负载报告。该业务量负载报告也可以表示客户前置装置所接收到的业务量负载信息。
在S710中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU发送(即,从客户前置装置中的MT功能向CU或宿主DU报告)业务量负载报告、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU发送(即,从DU向CU报告)业务量负载报告。
在S711中,高空平台站确定客户前置装置进入开启状态。
在S712中,高空平台站中的CU可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入开启状态、或仅通知开启状态的配置信息,高空平台站中的CU也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU通知)用于指示客户前置装置进入开启状态、或仅通知开启状态的配置信息。客户前置装置基于进入开启状态的该指示或所通知的该开启状态而进入开启状态。
此外,在S712中说明的是,高空平台站根据所接收到的业务量负载信息而确定客户前置装置进入开启状态。然而,高空平台站也可以根据所接收到的业务量负载信息而确定客户前置装置进入与半休眠状态不同的其他状态。即,高空平台站也可以根据所接收到的业务量负载信息而确定客户前置装置脱离半休眠状态。
在该情况下,如上所述,在S712中,也可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入与半休眠状态不同的其他状态、或者仅报告该其他状态的配置信息、或者高空平台站中的CU也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU报告)用于指示客户 前置装置进入与半休眠状态不同的其他状态、或者仅报告该其他状态的配置信息。
如上,说明了客户前置装置基于业务量负载信息或配置信息的至少一个而确定进入半休眠状态,并且,在客户前置装置处于半休眠状态的情况下,客户前置装置自身确定从半休眠状态脱离而进入与半休眠状态不同的其他状态的过程,也说明了客户前置装置基于从高空平台站发送的配置信息而确定从半休眠状态脱离而进入与半休眠状态不同的其他状态的过程。
半休眠状态下客户前置装置所关闭的功能与全休眠状态下客户前置装置所关闭的功能大致相同,但在半休眠状态下,客户前置装置的发送单元能够以预定时间间隔发送用于检测业务量负载的参考信号。
因此,通过使客户前置装置进入半休眠状态,在半休眠状态下,客户前置装置的发送单元能够以预定时间间隔发送用于检测业务量负载的参考信号,因此,相比全休眠状态,半休眠状态下能够更快地检测半静态和动态的业务量负载变化,由此,能够更快地应对该变化,进而提供更低的传输延迟。与此同时,与全休眠状态相比,半休眠状态下的客户前置装置的部分通信功能仍然被关闭,因此,在一定程度上,用于该客户前置装置的频率资源也能够被用于其他客户前置装置,能够增加资源利用率,并且,也能够降低功耗。此外,由于客户前置装置的部分通信功能被关闭,也能够减小对其他客户前置装置的通信干扰。
因此,通过将休眠状态进一步定义为半休眠状态和全休眠状态,能够更灵活地应对不同的业务量负载的情况。
参照图3来说明根据本公开的实施例的高空平台站(HAPS:High Altitude Platform Station)。图3是本公开的实施例的高空平台站的示意图。如图3所示,高空平台站300具备接收单元310、发送单元320以及控制单元330。
根据本公开的一实施例的高空平台站,包括控制单元,被配置为确定客户前置装置进入开启状态或非开启状态,所述非开启状态至少包括休眠状态;以及发送单元,被配置为发送用于指示所述客户前置装置进入所述开启状态或所述非开启状态的配置信息。如上所述,休眠状态也可以包括半休眠状态和全休眠状态。非开启状态也可以包括空闲状态。
发送单元320也可以经由DCI、RRC或MAC CE通过新的信令向客户前 置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入开启状态或非开启状态的配置信息、或者高空平台站中的CU也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU报告)用于指示客户前置装置进入开启状态或非开启状态的配置信息。非开启状态至少包括休眠状态。非开启状态也可以包括空闲状态。
根据本公开的一实施例的高空平台站,还包括接收单元310,接收从客户前置装置200发送的业务量负载报告,控制单元330基于业务量负载报告而确定客户前置装置200进入开启状态或非开启状态。高空平台站300基于从客户前置装置200发送来的业务量负载报告,生成基于业务量负载报告的配置信息,将所生成的配置信息发送给客户前置装置200。非开启状态至少包括休眠状态。非开启状态也可以包括空闲状态。
高空平台站300也可以不基于从客户前置装置200发送来的业务量负载报告,而生成配置信息。
在以上的说明中提到了客户前置装置200的空闲状态,下面对该空闲状态进行详细说明。
首先,参考图8,针对处于空闲状态下的客户前置装置确定转换到与空闲状态不同的其他状态的情况进行说明。
在图8中举出转换到与空闲状态不同的开启状态的例子,但也可以转换到与空闲状态不同的其他状态。
在S801中,客户前置装置的发送单元220也可以向用户终端以预定时间间隔发送用于检测业务量负载的SSB或CSI-RS。该SSB或CSI-RS与用于NR中初始接入的SSB或CSI-RS相同。
上述预定时间间隔可以由高空平台站而设置、也可以由高空平台站预先设定。
SSB或CSI-RS的发送时间间隔也可以是大于3GPP版本15、16、17中规定的最大时间间隔,即大于最大周期。
在S802中,用户终端接收到用于检测业务量负载的SSB或CSI-RS后,估计业务量负载。如上所述,业务量负载可以是瞬时的、也可以是一段期间内的累计值或者平均值等,本发明并不对此进行限定。该业务量负载也可以 是基于参考信号而做出的。
在S802中,由于用户终端估计出没有业务量负载,因此,不向客户前置终端发送业务量请求。
在S803中,由于客户前置装置在特定的定时没有收到用户终端发送的业务量请求,因此,判断为用户终端没有业务量负载,进而,客户前置装置确定进入空闲状态。
空闲状态下客户前置装置所关闭的功能与全休眠状态下客户前置装置所关闭的功能相比大体相同,但空闲状态下客户前置装置能够向用户终端发送SSB或CSI-RS。
如图8所示,处于空闲状态下的客户前置装置以预定时间间隔向用户终端发送用于检测业务量负载的SSB或CSI-RS。
即,在S805中,客户前置装置以预定时间间隔向用户终端发送下一个用于检测业务量负载的SSB或CSI-RS。
在S806中,用户终端接收到用于检测业务量负载的SSB或CSI-RS后,估计业务量负载。
与S802相同,估计出的业务量负载可以是瞬时的、也可以是一段期间内的累计值或者平均值等,本发明并不对此进行限定。该业务量负载也可以是基于参考信号而做出的。
在S807中,在估计出存在业务量负载的情况下,用户终端向客户前置装置反馈业务量需求。
在S808中,客户前置装置根据所接收到的业务量需求确定客户前置装置进入开启状态。
具体来说,客户前置装置200的控制单元230也可以在业务量负载信息高于特定阈值的情况下,确定客户前置装置200进入开启状态。该特定阈值可以是客户前置装置设定的,也可以基于高空平台站通知的信息而被设定的。显然,本发明并非仅限定为客户前置装置200的控制单元230仅在业务量负载信息高于特定阈值的的情况下,确定客户前置装置200进入开启状态,客户前置装置200的控制单元230也可以在业务量负载信息相比于特定阈值的其他情况下,确定客户前置装置200进入开启状态。
此外,在S808中说明的是,客户前置装置根据所接收到的业务量负载信息而确定客户前置装置进入开启状态。然而,客户前置装置也可以根据所接 收到的业务量负载信息而确定客户前置装置进入与空闲状态不同的其他状态。即,客户前置装置也可以根据所接收到的业务量负载信息而确定客户前置装置脱离空闲状态。
此外,从空闲状态进入与空闲状态不同的其他状态、以及从与空闲状态不同的其他状态进入空闲状态也可以不向高空平台站报告。
因此,通过使客户前置装置进入空闲状态,在空闲状态下,客户前置装置的发送单元能够以预定时间间隔发送用于检测业务量负载的SSB或CSI-RS,由此,能够更快地检测半静态和动态的业务量负载变化,并应对该变化,进而提供更低的传输延迟。与此同时,与全休眠状态相比,空闲状态下的客户前置装置的部分通信功能仍然被关闭,因此,在一定程度上,用于该客户前置装置的频率资源也能够被用于其他客户前置装置,能够增加资源利用率,并且,也能够降低功耗。此外,由于客户前置装置的部分通信功能被关闭,因此也能够减小对其他客户前置装置的通信干扰。
进一步,由于用于检测业务量负载的参考信号采用了与NR相同的SSB或CSI-RS,因此能够提高与目前NR系统的兼容性。
此外,在上述对于实施例的说明中,在图4和图5中说明了例如客户前置装置进入全休眠状态,并从全休眠状态转换到开启状态的例子,在图6和图7中说明了客户前置装置进入半休眠状态,并从半休眠状态转换到开启状态的例子,在图8中说明了客户前置装置进入空闲状态,并从空闲状态转换到开启状态的例子。
但是关于上述开启状态、空闲状态、半休眠状态、全休眠状态这四个状态的转换,并不限定于上述的状态转换的例子。客户前置装置也可以从上述某一状态转换到与该状态不同的其他状态。即,本发明的四个状态之间能够任意转换,从而能够更灵活地配置客户前置装置的状态。
此外,客户前置装置也可以不支持四个状态之间的任意转换,而是仅支持图4~图8中示出的状态转换,即仅支持客户前置装置进入全休眠状态并从全休眠状态转换到开启状态,客户前置装置进入半休眠状态并从半休眠状态转换到开启状态,客户前置装置进入空闲状态并从空闲状态转换到开启状态,由此,能够实现客户前置装置内的配置简单化和低成本化。
进一步,客户前置装置也可以支持上述四个状态中的部分状态之间的转 换。也可以是,仅支持特定状态向开启状态和与该特定状态相邻的状态之间的转换。比如,全休眠状态也可以转换为半休眠状态和开启状态,半休眠状态也可以转为空闲状态和开启状态,空闲状态也可以转为开启状态等。由此,能够在一定程度上实现客户前置装置内的配置简单化、低成本化的同时,能够灵活地配置客户前置装置的状态。
此外,以上说明的状态转换也可以按每个带域而被分别进行。即,基于业务量负载和干扰,按每个带域而分别进行客户前置装置的状态转换。下面举出基于业务量负载而进行状态转换的情况进行说明。
例如,如上所述,对各个带域设定公共的阈值,基于上述实施例中说明了的流程,按每个带域而分别控制客户前置装置的状态转换。
也可以按每个带域而设定各自的阈值,同样地基于上述实施例中说明了的流程,按每个带域而分别控制客户前置装置的状态转换。
也可以对所有带域设定总阈值,基于各个带域的业务量负载之和与总阈值之间的关系,控制对于所有带域的状态转换。例如,在各个带域的业务量负载之和大于总阈值的情况下,针对所有带域而使客户前置装置转换为开启状态。而在各个带域的业务量负载之和是总阈值以下的情况下,针对所有带域而使客户前置装置转换为例如休眠状态。
如上所述,上述具体状态的转换只是一例,各个状态之间的转换是任意的。
另外,关于上述全休眠状态、半休眠状态、空闲状态,从能量效率的观点来看,全休眠状态下的客户前置装置的能量效率大于半休眠状态下的客户前置装置的能量效率,半休眠状态下的客户前置装置的能量效率大于空闲状态下的客户前置装置的能量效率。
从传输延迟的观点来看,空闲状态下的客户前置装置的传输延迟小于半休眠状态下的客户前置装置的传输延迟,半休眠状态下的客户前置装置的传输延迟小于全休眠状态下的客户前置装置的传输延迟。
以上结合图4~8说明了根据本发明的实施例的客户前置装置、用户终端、高空平台站之间的通信流程,在上述说明中以划分为各个单元的方式进行了说明,例如,控制单元、接收单元、发送单元等,然而,也可以以划分为各 个步骤的方式进行说明,即,以控制步骤、接收步骤、发送步骤的方式说明图4~8的客户前置装置、用户终端、高空平台站的通信流程。
以下,结合流程图(图4~8)和示意图(图9、10)说明由客户前置装置执行的通信方法以及由高空平台站执行的通信方法。
接下来,参照图9来说明根据本公开的一个实施例的由客户前置装置(CPE:Customer premises equipment)执行的通信方法。图9是本公开的实施例的由客户前置装置执行的通信方法的示意图。
如图9所示,由客户前置装置执行的通信方法900包括步骤S910和S920,在S910中,接收业务量负载信息和配置信息中的至少一个,在S920中,根据接收到的业务量负载信息和配置信息中的至少一个来确定客户前置装置进入开启状态或非开启状态,所述非开启状态至少包括休眠状态。所述非开启状态也可以包括空闲状态。
业务量负载(traffic load)信息可以由用户终端发送给客户前置装置,该业务量负载(traffic load)信息可以表示用户终端当前时刻的瞬时业务量负载,也可以表示特定的时刻的业务量负载,也可以表示特定期间内的业务量负载的累计或者平均值,如从当前的时刻起之后一段时间内的业务量负载累计或者平均值,也可以表示未来特定的时刻的预测的业务量负载,还可以表示未来特定期间内的预测的业务量负载的累计或者平均值,但本发明并不限定于上述形式。用户终端可以通过各种公知的方法来计算、估计、或预测上述业务量负载,也可以从其他设备来获得用户终端的业务量负载。
配置信息可以由高空平台站发送给客户前置装置。该配置信息可以用于指示客户前置装置进入开启状态或非开启状态,所述非开启状态至少包括休眠状态。所述非开启状态也可以包括空闲状态。配置信息也可以基于业务量负载而被确定。
可替换地,客户前置装置也可以接收其他信息,并基于该信息而确定客户前置装置进入开启状态或非开启状态,所述非开启状态至少包括休眠状态。所述非开启状态也可以包括空闲状态。可替换地,客户前置装置也可以根据预先被设定的准则(criteria)而确定客户前置装置进入开启状态或非开启状态,所述非开启状态至少包括休眠状态。所述非开启状态也可以包括空闲状态。预先被设定的准则(criteria)可以与上述用户终端的业务量负载信息或 配置信息有关,但并不限定于此,也可以是与客户前置装置的实现有关的其他信息。
根据本公开的另一实施例的由客户前置装置执行的通信方法,还包括以下步骤:在休眠状态下,当关于所述客户前置装置的条件被满足时,确定客户前置装置转换到与休眠状态不同的其他状态。
上述其他状态可以是上文中提到的开启状态、空闲状态的一方,也可以是客户前置装置的其他状态。
关于所述客户前置装置的条件可以是,客户前置装置可以设定定时器,若该定时器期满,则表示关于所述客户前置装置的条件被满足。
关于所述客户前置装置的条件也可以是,客户前置装置设定特定阈值,若从用户终端发送而来的业务量负载大于或等于该特定阈值,则表示关于所述客户前置装置的条件被满足。当然,关于所述客户前置装置的条件也可以是,从用户终端发送而来的业务量负载与该特定阈值相比的其他关系。对定时器或者阈值等的设定可以是客户前置装置自行设定的,也可以是客户前置装置基于上位站的(如,高空平台站)的指示而设定的。
根据本公开的另一实施例的由客户前置装置执行的通信方法,还包括以下步骤:从高空平台站接收配置信息,以及在休眠状态下根据配置信息确定客户前置装置转换到与所述休眠状态不同的其他状态。
该配置信息也可以用于指示客户前置装置进入开启状态、空闲状态、或与休眠状态不同的其他状态。
此外,客户前置装置也可以经由DCI、RRC或MAC CE通过新的信令来接收从高空平台站发来的配置信息,或者通过F1-AP信令来接收从高空平台站发来的配置信息。也可以是,配置信息从作为CU或者宿主DU(Donor-DU)的高空平台站被发送到客户前置装置的移动终端(MT:Mobile Terminal)功能模块。也可以是,配置信息从作为CU的高空平台站被发送到作为DU的客户前置装置。客户前置装置也可以通过其他信道和其他信令来接收从高空平台站发来的配置信息。
根据本公开的另一实施例的由客户前置装置执行的通信方法,还包括以 下步骤:休眠状态包括全休眠状态,在全休眠状态下仅用于确定客户前置装置转换到与全休眠状态不同的其他状态。
具体来说,在全休眠状态下,客户前置装置也可以关闭全部DU功能、全部与用户终端进行发送和接收的功能,即关闭包括PDSCH、PDCCH、PUSCH、PUCCH、PRACH、其他信道在内的、与用户终端之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB、CSI-RS、SRS、其他参考信道在内的与用户终端之间的上下行参考信号的发送和接收。
可替代地,在全休眠状态下,客户前置装置也可以在关闭上述功能的基础上,关闭全部MT功能、全部与CU或宿主DU(Donor-DU)之间进行发送和接收的功能,即关闭包括PDSCH、PDCCH、PUSCH、PUCCH、PRACH、其他信道在内的、与CU或宿主DU(Donor-DU)之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB、CSI-RS、SRS、其他参考信道在内的与CU或宿主DU(Donor-DU)之间的上下行参考信号的发送和接收。
也就是说,在全休眠状态下,至少客户前置装置的DU的功能全部被关闭,客户前置装置无法与用户终端进行通信,客户前置装置也就不能接收来自用户终端自行发送的信息(如调度请求),进而也就无法基于来自用户终端自行发送的信息而做出相应的反馈。
进一步,对全休眠状态的情况下客户前置装置的通信过程进行说明。
首先,参考图4,针对处于全休眠状态下的客户前置装置自身确定转换到与全休眠状态不同的其他状态的情况进行说明。
在图4中举出转换到与全休眠状态不同的开启状态的例子,但也可以转换到与全休眠状态不同的其他状态。
在S401中,如上所述,客户前置装置可以根据接收到的业务量负载信息和配置信息中的至少一个而确定客户前置装置进入全休眠状态。
在S402中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置中的MT功能向CU或宿主DU报告)客户前置装置进入全休眠状态、或者仅报告全休眠状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从DU向CU报告)客户前置装置进入全休眠状态、或者仅报告全休眠状态。
该报告的定时可以是在客户前置装置进入到全休眠状态之前。也就是说, 客户前置装置可以在发送该报告后进入全休眠状态,或者,客户也可以在发送该报告给高空平台站,并接收到高空平台站的确认信息后,进入全休眠状态。
该报告的定时也可以是在客户前置装置进入到全休眠状态之后。在该情况下,客户前置装置在全休眠状态下仍然具有发送该报告给高空平台站的功能。
在S403中,客户前置装置也可以在关于客户前置装置的条件(如定时器期满)被满足时,确定转移到与全休眠状态不同的其他状态,例如开启状态。
在S404中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置中的MT功能向CU或宿主DU报告)客户前置装置转移到该其他状态、或者仅报告该其他状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从DU向CU报告)客户前置装置转移到该其他状态、或者仅报告该其他状态。
该报告的定时可以是在客户前置装置进入到所转移的该其他状态之前。也就是说,客户前置装置可以在发送该报告后进入到所转移的该状态,或者,客户前置装置也可以在发送该报告给高空平台站,并接收到高空平台站的确认信息后,进入到所转移的该状态。
该报告的定时也可以是在客户前置装置进入到所转移的该状态之后。即,在客户前置装置进入到所转移的该状态之后,该客户前置装置向高空平台站发送该报告。在该情况下,客户前置装置在该其他状态下仍然具有发送该报告给高空平台站的功能。
另外,参考图5,针对处于全休眠状态下的客户前置装置基于高空平台站发来的配置信息确定转换到与全休眠状态不同的其他状态的情况进行说明。
在图5中举出转换到与全休眠状态不同的开启状态的例子,但也可以转换到与全休眠状态不同的其他状态。
在S501中,高空平台站可以确定客户前置装置进入全休眠状态。
在S502中,高空平台站可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入全休眠状态的配置信息、或者高空平台站 也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU发送)用于指示客户前置装置进入全休眠状态的配置信息。客户前置装置在接收到该配置信息后,根据该配置信息而确定进入全休眠状态。之后,客户前置装置进入全休眠状态。
在S503中,高空平台站也可以确定客户前置装置进入与全休眠状态不同的其他状态,例如开启状态。
在S504中,高空平台站可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入与全休眠状态不同的其他状态的配置信息、或者高空平台站也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU发送)用于指示客户前置装置进入与全休眠状态不同的其他状态的配置信息。客户前置装置在接收到该配置信息后,根据该配置信息而确定进入与全休眠状态不同的其他状态。之后,客户前置装置进入与全休眠状态不同的其他状态。
如上,说明了客户前置装置基于业务量负载信息或配置信息的至少一个而确定进入全休眠状态,并且,在客户前置装置处于全休眠状态的情况下,客户前置装置自身确定从全休眠状态脱离而进入与全休眠状态不同的其他状态的过程,也说明了客户前置装置基于从高空平台站发送的配置信息而确定从全休眠状态脱离而进入与全休眠状态不同的其他状态的过程。
客户前置装置处于全休眠状态的情况下,客户前置装置关闭全部DU功能、全部与用户终端之间进行发送和接收的通信功能,即关闭包括PDSCH、PDCCH、PUSCH、PUCCH、PRACH、其他信道在内的、与用户终端之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB、CSI-RS、SRS、其他参考信道在内的与用户终端之间的上下行参考信号的发送和接收。
可替代地,客户前置装置处于全休眠状态的情况下,客户前置装置关闭全部DU功能、全部与用户终端之间进行发送和接收的通信功能,即关闭包括PDSCH、PDCCH、PUSCH、PUCCH、PRACH、其他信道在内的、与用户终端之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB、CSI-RS、SRS、其他参考信道在内的、与用户终端之间的上下行参考信号的发送和接收,在这个基础上,客户前置装置还关闭全部MT功能、全部 与CU和宿主DU之间的发送和接收的功能,即关闭包括PDSCH、PDCCH、PUSCH、PUCCH、PRACH、其他信道在内的、与CU和宿主DU之间的上下行控制信道和上下行数据信道的发送和接收,以及关闭包括SSB、CSI-RS、SRS、其他参考信道在内的与CU和宿主DU之间的上下行参考信号的发送和接收。
因此,通过使客户前置装置进入全休眠状态,使得客户前置装置的上述功能被关闭,用于该客户前置装置的频率资源可以被用于其他客户前置装置,能够增加资源利用率,并且,也能够降低功耗。此外,由于客户前置装置的上述功能被关闭,也能够减小对其他客户前置装置的通信干扰。
根据本公开的另一实施例的由客户前置装置执行的通信方法,还包括以下步骤:休眠状态包括半休眠状态,在半休眠状态下,以预定时间间隔发送用于检测业务量负载的参考信号。
具体来说,在半休眠状态下,与全休眠状态相比,客户前置装置能够以预定时间间隔发送用于检测业务量负载的参考信号。而在全休眠状态下,客户前置装置无法发送用于检测业务量负载的参考信号。
进一步,对半休眠状态的情况下客户前置装置的通信过程进行说明。
参考图6,针对处于半休眠状态下的客户前置装置自身确定转换到与半休眠状态不同的其他状态的情况进行说明。
在图6中举出转换到与半休眠状态不同的开启状态的例子,但也可以转换到与半休眠状态不同的其他状态。
在S601中,如上所述,客户前置装置也可以向用户终端以预定时间间隔发送用于检测业务量负载的参考信号。
上述预定时间间隔可以由高空平台站而设置、也可以由高空平台站预先设定。
进一步,该参考信号也可以不同于与3GPP版本15、16、17中的参考信号。该参考信号也可以是SSB,但该情况下发送该SSB的预定时间间隔大于3GPP版本15、16、17中规定的最大时间间隔,即大于最大周期。
在S602中,用户终端接收到用于检测业务量负载的参考信号后,估计业务量负载。如上所述,业务量负载可以是瞬时的、也可以是一段期间内的累计值或者平均值等,本发明并不对此进行限定。该业务量负载也可以是基于 参考信号而做出的。
在S603中,若用户终端估计出的业务量负载是低业务量负载,则将表示该低业务量负载的业务量负载信息反馈给客户前置装置。
在S604中,客户前置装置根据所接收到的业务量负载信息而确定客户前置装置进入半休眠状态。
具体来说,客户前置装置也可以在业务量负载信息低于特定阈值的情况下,确定客户前置装置进入半休眠状态。该特定阈值可以是客户前置装置设定的,也可以基于高空平台站通知的信息而被设定的。显然,本发明并非仅限定为客户前置装置仅在业务量负载信息小于特定阈值的的情况下,确定客户前置装置进入半休眠状态,客户前置装置也可以在业务量负载信息相比于特定阈值的其他情况下,确定客户前置装置进入半休眠状态。
在S605中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置中的MT功能向CU或宿主DU报告)客户前置装置进入半休眠状态、或者仅报告半休眠状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从DU向CU报告)客户前置装置进入半休眠状态、或者仅报告半休眠状态。
该报告的定时可以是在客户前置装置进入到半休眠状态之前。也就是说,客户前置装置可以在发送该报告后进入半休眠状态,或者,客户也可以在发送该报告给高空平台站,并接收到高空平台站的确认信息后,进入半休眠状态。
该报告的定时也可以是在客户前置装置进入到半休眠状态之后。在该情况下,客户前置装置在半休眠状态下仍然具有发送该报告给高空平台站的功能。
在S606中,由于客户前置装置以预定时间间隔发送用于检测业务量负载的参考信号,因此,客户前置装置以预定时间间隔向用户终端发送下一个用于检测业务量负载的参考信号。
在S607中,同S602步骤,用户终端接收到用于检测业务量负载的参考信号后,估计业务量负载。
在S608中,若用户终端估计出的业务量负载是高业务量负载,则将表示该高业务量负载的业务量负载信息反馈给客户前置装置。
在S609中,客户前置装置根据所接收到的业务量负载信息而确定客户前 置装置进入开启状态。
具体来说,客户前置装置也可以在业务量负载信息高于特定阈值的情况下,确定客户前置装置进入开启状态。该特定阈值可以是客户前置装置设定的,也可以基于高空平台站通知的信息而被设定的。显然,本发明并非仅限定为客户前置装置仅在业务量负载信息高于特定阈值的的情况下,确定客户前置装置进入开启状态,客户前置装置也可以在业务量负载信息相比于特定阈值的其他情况下,确定客户前置装置进入开启状态。
在S610中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置中的MT功能向CU或宿主DU报告)客户前置装置进入开启状态、或者仅报告开启状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从DU向CU报告)客户前置装置进入开启状态、或者仅报告开启状态。
该报告的定时可以是在客户前置装置进入到开启状态之前。也就是说,客户前置装置可以在发送该报告后进入开启状态,或者,客户也可以在发送该报告给高空平台站,并接收到高空平台站的确认信息后,进入开启状态。
该报告的定时也可以是在客户前置装置进入到开启状态之后。
此外,在S609中说明的是,客户前置装置根据所接收到的业务量负载信息而确定客户前置装置进入开启状态。然而,客户前置装置也可以根据所接收到的业务量负载信息而确定客户前置装置进入与半休眠状态不同的其他状态。即,客户前置装置也可以根据所接收到的业务量负载信息而确定客户前置装置脱离半休眠状态。
在该情况下,如上所述,在S610中,客户前置装置也可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU报告(即,从客户前置装置中的MT功能向CU或宿主DU报告)客户前置装置进入与半休眠状态不同的其他状态、或者仅报告该其他状态、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU报告(即,从DU向CU报告)客户前置装置进入与半休眠状态不同的其他状态、或者仅报告该其他状态。
接下来,参考图7,针对处于半休眠状态下的客户前置装置基于高空平台站发来的配置信息确定转换到与半休眠状态不同的其他状态的情况进行说明。为了便于阅读,对与图6相同的步骤简略地进行说明。
在图7中举出转换到与半休眠状态不同的开启状态的例子,但也可以转 换到与半休眠状态不同的其他状态。
在S701中,同S601,客户前置装置也可以向用户终端以预定时间间隔发送用于检测业务量负载的参考信号。
在S702中,用户终端接收到用于检测业务量负载的参考信号后,估计业务量负载。
在S703中,若用户终端估计出的业务量负载是低业务量负载,则将表示该低业务量负载的业务量负载信息反馈给客户前置装置。
在S704中,客户前置装置根据所接收到的业务量负载信息而向高空平台站发送业务量负载报告。该业务量负载报告也可以表示客户前置装置所接收到的业务量负载信息。
在S704中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU发送(即,从客户前置装置中的MT功能向CU或宿主DU报告)业务量负载报告、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU发送(即,从DU向CU报告)业务量负载报告。
在S705中,高空平台站确定客户前置装置进入半休眠状态。
在S706中,高空平台站中的CU可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置指示(即,从CU或宿主DU向客户前置装置中的MT功能通知)客户前置装置进入半休眠状态、或仅通知半休眠状态,高空平台站中的CU也可以通过F1-AP信令向客户前置装置指示(即,从CU向DU通知)客户前置装置进入半休眠状态、或仅通知半休眠状态。客户前置装置基于进入半休眠状态的该指示或所通知的该半休眠状态而进入半休眠状态。
在S707中,由于客户前置装置在半休眠状态下以预定时间间隔发送用于检测业务量负载的参考信号,因此,处于半休眠状态下的客户前置装置以预定时间间隔向用户终端发送下一个用于检测业务量负载的参考信号。
在S708中,同S702步骤,用户终端接收到用于检测业务量负载的参考信号后,估计业务量负载。
在S709中,若用户终端估计出的业务量负载是高业务量负载,则将表示该高业务量负载的业务量负载信息反馈给客户前置装置。
在S710中,客户前置装置根据所接收到的业务量负载信息而向高空平台站发送业务量负载报告。该业务量负载报告也可以表示客户前置装置所接收 到的业务量负载信息。
在S710中,客户前置装置可以经由UCI、RRC或MAC CE通过新的信令向高空平台站中的CU发送(即,从客户前置装置中的MT功能向CU或宿主DU报告)业务量负载报告、或者客户前置装置也可以通过F1-AP信令向高空平台站中的CU发送(即,从DU向CU报告)业务量负载报告。
在S711中,高空平台站确定客户前置装置进入开启状态。
在S712中,高空平台站中的CU可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入开启状态、或仅通知开启状态的配置信息,高空平台站中的CU也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU通知)用于指示客户前置装置进入开启状态、或仅通知开启状态的配置信息。客户前置装置基于进入开启状态的该指示或所通知的该开启状态而进入开启状态。
此外,在S712中说明的是,高空平台站根据所接收到的业务量负载信息而确定客户前置装置进入开启状态。然而,高空平台站也可以根据所接收到的业务量负载信息而确定客户前置装置进入与半休眠状态不同的其他状态。即,高空平台站也可以根据所接收到的业务量负载信息而确定客户前置装置脱离半休眠状态。
在该情况下,如上所述,在S712中,也可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入与半休眠状态不同的其他状态、或者仅报告该其他状态的配置信息、或者高空平台站中的CU也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU报告)用于指示客户前置装置进入与半休眠状态不同的其他状态、或者仅报告该其他状态的配置信息。
如上,说明了客户前置装置基于业务量负载信息或配置信息的至少一个而确定进入半休眠状态,并且,在客户前置装置处于半休眠状态的情况下,客户前置装置自身确定从半休眠状态脱离而进入与半休眠状态不同的其他状态的过程,也说明了客户前置装置基于从高空平台站发送的配置信息而确定从半休眠状态脱离而进入与半休眠状态不同的其他状态的过程。
半休眠状态下客户前置装置所关闭的功能与全休眠状态下客户前置装置 所关闭的功能大致相同,但在半休眠状态下,客户前置装置能够以预定时间间隔发送用于检测业务量负载的参考信号。
因此,通过使客户前置装置进入半休眠状态,在半休眠状态下,客户前置装置能够以预定时间间隔发送用于检测业务量负载的参考信号,因此,相比全休眠状态,半休眠状态下能够更快地检测半静态和动态的业务量负载变化,由此,能够更快地应对该变化,进而提供更低的传输延迟。与此同时,与全休眠状态相比,半休眠状态下的客户前置装置的部分通信功能仍然被关闭,因此,在一定程度上,用于该客户前置装置的频率资源也能够被用于其他客户前置装置,能够增加资源利用率,并且,也能够降低功耗。此外,由于客户前置装置的部分通信功能被关闭,也能够减小对其他客户前置装置的通信干扰。
因此,通过将休眠状态进一步定义为半休眠状态和全休眠状态,能够更灵活地应对不同的业务量负载的情况。
参照图10来说明根据本公开的实施例的由高空平台站(HAPS:High Altitude Platform Station)执行的通信方法。图10是本公开的实施例的由高空平台站执行的通信方法的示意图。如图10所示,由高空平台站执行的通信方法1000具备步骤S1010和S1020。在步骤S1010中,确定客户前置装置进入开启状态或非开启状态,所述非开启状态至少包括休眠状态,在步骤S1020中,发送用于指示所述客户前置装置进入所述开启状态或所述非开启状态配置信息。如上所述,休眠状态也可以包括半休眠状态和全休眠状态。所述非开启状态也可以包括空闲状态。
高空平台站也可以经由DCI、RRC或MAC CE通过新的信令向客户前置装置发送(即,从CU或宿主DU向客户前置装置中的MT功能发送)用于指示客户前置装置进入开启状态或非开启状态的配置信息、或者高空平台站中的CU也可以通过F1-AP信令向客户前置装置发送(即,从CU向DU报告)用于指示客户前置装置进入开启状态或非开启状态的配置信息。非开启状态至少包括休眠状态。非开启状态也可以包括空闲状态。
根据本公开的一实施例的由高空平台站执行的方法,还包括以下步骤:接收从客户前置装置发送的业务量负载报告,基于业务量负载报告而确定客 户前置装置进入开启状态或非开启状态。高空平台站基于从客户前置装置发送来的业务量负载报告,生成基于业务量负载报告的配置信息,将所生成的配置信息发送给客户前置装置。非开启状态至少包括休眠状态。非开启状态也可以包括空闲状态。高空平台站也可以不基于从客户前置装置发送来的业务量负载报告,而生成配置信息。
在以上对于通信方法的说明中提到了客户前置装置的空闲状态,下面对该空闲状态的通信流程进行详细说明。
参考图8,针对处于空闲状态下的客户前置装置确定转换到与空闲状态不同的其他状态的情况进行说明。
在图8中举出转换到与空闲状态不同的开启状态的例子,但也可以转换到与空闲状态不同的其他状态。
在S801中,客户前置装置也可以向用户终端以预定时间间隔发送用于检测业务量负载的SSB或CSI-RS。该SSB或CSI-RS与用于NR中初始接入的SSB或CSI-RS相同。
上述预定时间间隔可以由高空平台站而设置、也可以由高空平台站预先设定。
SSB或CSI-RS的发送时间间隔也可以是大于3GPP版本15、16、17中规定的最大时间间隔,即大于最大周期。
在S802中,用户终端接收到用于检测业务量负载的SSB或CSI-RS后,估计业务量负载。如上所述,业务量负载可以是瞬时的、也可以是一段期间内的累计值或者平均值等,本发明并不对此进行限定。该业务量负载也可以是基于参考信号而做出的。
在S802中,由于用户终端估计出没有业务量负载,因此,不向客户前置终端发送业务量请求。
在S803中,由于客户前置装置在特定的定时没有收到用户终端发送的业务量请求,因此,判断为用户终端没有业务量负载,进而,客户前置装置确定进入空闲状态。
空闲状态下客户前置装置所关闭的功能与全休眠状态下客户前置装置所关闭的功能相比大体相同,但空闲状态下客户前置装置能够向用户终端发送SSB或CSI-RS。
如图8所示,处于空闲状态下的客户前置装置以预定时间间隔向用户终端发送用于检测业务量负载的SSB或CSI-RS。
即,在S805中,客户前置装置以预定时间间隔向用户终端发送下一个用于检测业务量负载的SSB或CSI-RS。
在S806中,用户终端接收到用于检测业务量负载的SSB或CSI-RS后,估计业务量负载。
与S802相同,估计出的业务量负载可以是瞬时的、也可以是一段期间内的累计值或者平均值等,本发明并不对此进行限定。该业务量负载也可以是基于参考信号而做出的。
在S807中,在估计出存在业务量负载的情况下,用户终端向客户前置装置反馈业务量需求。
在S808中,客户前置装置根据所接收到的业务量需求确定客户前置装置进入开启状态。
具体来说,客户前置装置也可以在业务量负载信息高于特定阈值的情况下,确定客户前置装置进入开启状态。该特定阈值可以是客户前置装置设定的,也可以基于高空平台站通知的信息而被设定的。显然,本发明并非仅限定为客户前置装置仅在业务量负载信息高于特定阈值的的情况下,确定客户前置装置进入开启状态,客户前置装置也可以在业务量负载信息相比于特定阈值的其他情况下,确定客户前置装置进入开启状态。
此外,在S808中说明的是,客户前置装置根据所接收到的业务量负载信息而确定客户前置装置进入开启状态。然而,客户前置装置也可以根据所接收到的业务量负载信息而确定客户前置装置进入与空闲状态不同的其他状态。即,客户前置装置也可以根据所接收到的业务量负载信息而确定客户前置装置脱离空闲状态。
此外,从空闲状态进入与空闲状态不同的其他状态、以及从与空闲状态不同的其他状态进入空闲状态也可以不向高空平台站报告。
因此,通过使客户前置装置进入空闲状态,在空闲状态下,客户前置装置能够以预定时间间隔发送用于检测业务量负载的SSB或CSI-RS,由此,能够更快地检测半静态和动态的业务量负载变化,并应对该变化,进而提供更低的传输延迟。与此同时,与全休眠状态相比,空闲状态下的客户前置装置的部分通信功能仍然被关闭,因此,在一定程度上,用于该客户前置装置的 频率资源也能够被用于其他客户前置装置,能够增加资源利用率,并且,也能够降低功耗。此外,由于客户前置装置的部分通信功能被关闭,因此也能够减小对其他客户前置装置的通信干扰。
进一步,由于用于检测业务量负载的参考信号采用了与NR相同的SSB或CSI-RS,因此能够提高与目前NR系统的兼容性。
