确定可用于传输的资源的方法及装置
相关申请的交叉引用
本申请主张在2019年3月29日在中国提交的中国专利申请号No.201910252055.4的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种确定可用于传输的资源的方法及装置。
背景技术
随着通信技术的发展,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)引入自回传技术。
如图1所示,具备自回传能力的通信设备2既能够通过接入链路(Access Link)为终端3提供服务,又能够通过回传链路(Backhaul Link)将数据回传至具有光纤传输能力的通信设备1。
而自回传技术的资源分配的方式可以分为时分复用模式(Time Division Multiplexing,TDM)、频分复用模式(Frequency Division Multiplexing,FDM)和空分复用模式(Space Division Multiplexing,SDM)的复用方式,各自对应的资源分配方式如图2、图3和图4所示。
具备自回传能力的通信设备包括两部分,即作为终端工作的移动终端(Mobile Terminal,MT)部分和作为基站工作的分布式单元(Distribution Unit,DU)部分,二者的工作受到半双工工作方式的限制。
相关技术中,为DU部分分配的资源包括多种资源类型,如第一类型的资源和第二类型的资源。然而相关技术的具备自回传能力的通信设备进行资源管理时,仅考虑资源的方向和位置,并没有考虑资源类型,因此无法进行准确有效的资源管理。
发明内容
本公开实施例的目的在于提供一种确定可用于传输的资源的方法及装置,以解决相关技术中的具备自回传能力的通信设备的资源管理不准确的问题。
为了解决上述技术问题,本公开实施例是这样实现的:
第一方面,本公开实施例提供了一种确定可用于传输的资源的方法,包括:
根据第一资源配置和第二资源配置中的至少一个,确定物理随机接入信道PRACH机会有效和/或无效,和/或确定可用于传输的资源。
第二方面,本公开实施例提供了一种确定可用于传输的资源的装置,包括:
确定模块,用于根据第一资源配置和第二资源配置中的至少一个,确定PRACH机会有效和/或无效,和/或确定可用于传输的资源。
第三方面,本公开实施例提供了一种通信设备,包括存储器、处理器及存储在所述存储器上并可在所述处理器上运行的计算机程序,其中,所述计算机程序被所述处理器执行时实现上述确定可用于传输的资源的方法的步骤。
第四方面,本公开实施例提供了一种计算机可读存储介质,其上存储有计算机程序,其中,所述计算机程序被处理器执行时实现上述确定可用于传输的资源的方法的步骤。
本公开实施例中,对于具有回传链路和接入链路的网络设备而言,根据回传链路对应的资源配置和接入链路对应的资源配置中的部分或全部,来确定PRACH机会有效和/或无效,和/或确定可用于传输的资源。由于本公开实施例在确定可用于传输的资源时,考虑了回传链路对应的资源配置和接入链路对应的资源配置,而不再是仅仅考虑自身配置的资源的方向和位置,因此能够提高资源管理的准确度。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
本公开实施例的目的在于提供一种确定可用于传输的资源的方法及装置,其根据回传链路对应的资源配置(Resource Configuration,Resource Configurations,或Resources Configurations)和接入链路对应的资源配置中的部分或全部,来确定物理随机接入信道(Physical Random Access Channel,PRACH)机会(也可称为:PRACH传输机会,Occasion)有效和/或无效,和/或确定可用于传输的资源。由于本公开实施例的方法在确定可用于传输的资源时,考虑了回传链路对应的资源配置和接入链路对应的资源配置,而不再是仅仅考虑自身配置的资源的方向和位置,因此能够提高资源管理的准确度。
相关技术中,为DU部分分配的资源包括多种资源类型,如第一类型的 资源、第二类型的资源,其中:
第一类型的资源,也可称之为软资源(Soft);对于这部分资源,其虽然配置给DU部分,但其使用需要DU部分根据MT部分的使用情况来确定资源是否可用,也就是说要根据MT部分是否使用该资源来判断该资源是否可用。换句话说,对于第一类型的资源,MT部分具有更高的使用优先权,而DU部分的使用优先权相对较低。
而第二类型的资源,也可称之为硬资源(Hard);对于这部分资源,可以是配置给DU部分独立使用的资源,或者,也可以是配置给DU部分,且DU部分比MT部分具有更高使用优先级的资源。
换句话说,对于第二类型的资源,DU部分可以不考虑MT部分对该资源的使用情况而使用该资源;或者说,DU部分可以任意使用该资源;或者说,DU部分可以任意使用该资源,且不考虑MT部分是否使用该资源;也就是说,对于第二类型的资源,相比于MT部分,DU部分拥有更高的使用优先权。
可理解的,本实施例中的资源可以是时域资源、频域资源,或者时频域的资源等。
本公开具体实施例的一种确定可用于传输的资源的方法,如图5所示,所述方法包括:
步骤501:根据第一资源配置和第二资源配置中的至少一个,确定PRACH机会有效和/或无效,和/或确定可用于传输的资源。
此步骤中的PRACH机会可以为PRACH接收机会,和/或PRACH发送机会。上述确定PRACH机会有效和/或无效可以表示确定PRACH接收机会和PRACH发送机会有效,也可表示确定PRACH接收机会和PRACH发送机会无效,也可表示确定PRACH接收机会有效,和确定PRACH发送机会无效,也可表示确定PRACH接收机会无效,和确定PRACH发送机会有效。
本公开具体实施例中,对于具有回传链路和接入链路的网络设备而言,根据回传链路对应的资源配置和接入链路对应的资源配置中的部分或全部,来确定PRACH机会有效和/或无效,和/或确定可用于传输的资源。由于本公开实施例的方法在确定可用于传输的资源时,考虑了回传链路对应的资源配置和接入链路对应的资源配置,而不再是仅仅考虑自身配置的资源的方向和 位置,因此能够提高资源管理的准确度。
本公开具体实施例中,所述第一资源配置可以是回传一体化(Integrated Access and Backhaul,IAB)装置的回传链路对应的资源配置,而所述第二资源配置可以是IAB装置的接入链路对应的资源配置。
在所述第一资源配置是IAB装置的回传链路对应的资源配置,而所述第二资源配置是IAB装置的接入链路对应的资源配置的情况下,相应的,所述PRACH机会为MT部分的PRACH机会,和/或,所述PRACH机会为DU部分的PRACH机会。DU部分可以是基站或者IAB的基站功能。
对于MT部分而言,所述PRACH机会为PRACH的发送机会,而对于DU部分而言,所述PRACH机会为PRACH的接收机会。
应当理解的是,本公开具体实施例中,上述的确定可用于传输的资源的方法既可以由具有回传链路和接入链路的网络设备自己来执行,也可以由其他的外部设备来执行,如网管设备等。
之前已经提到,自回传技术的资源分配的方式可以分为TDM、FDM和SDM的复用方式。以下以不同的工作模式下,说明如何根据第一资源配置和第二资源配置中的至少一个,确定PRACH机会有效和/或无效,和/或确定可用于传输的资源。
<MT部分和DU部分工作于时分模式>
当MT部分和DU部分工作于时分模式时,MT部分和DU部分各自在独立的时间段内独占资源,此时可以根据如下准则中的至少一个,确定PRACH机会有效和/或无效,和/或确定可用于传输的资源。
如下表1所示,相关技术的NR标准中,已经定义了上行随机接入信道(Random Access Channel,RACH)的周期和发送机会。终端能够根据基站的指示确定具体的PRACH周期和传输机会(RACH Occasion)。
表1
Figure PCTCN2020081431-appb-000001
Figure PCTCN2020081431-appb-000002
表1中,n SFNmod x=y。
同样,对于具备自回传能力的通信设备而言,其也可以根据PRACH的配置,确定MT部分和DU部分各自的PRACH传输机会(RACH Occasion)。由于MT部分和DU部分工作于半双工模式,DU部分在对应的时刻接收一般终端的上行PRACH时,MT部分不能进行上行RACH的发送。因此相关技术中,引入了周期的缩放因子(scaling)以及偏移(offset),使得MT部分的上行RACH发送机会与DU部分的上行PRACH接收机会能够正交开,相互不影响。
在依据上述的相关技术确定PRACH机会对应的资源后,需要依据回传链路对应的资源配置和接入链路对应的资源配置来确定PRACH机会有效和/或无效,继续说明如下。
准则1
如图6a所示,第一资源位于第三资源之外的情况下,PRACH机会为无效;所述第三资源为:配置给MT部分的资源;所述第一资源为:MT部分的PRACH机会(RO)对应的资源(也可称为:传输资源)。
这种情况下,确定的MT部分的PRACH发送机会所对应的资源并没有配置给MT部分,因此MT部分的PRACH机会为无效,MT部分无法利用这部分资源进行PRACH的发送。
准则2
如图6b所示,第一资源位于第三资源之内(此之内可以理解为第一资源与第三资源重叠,或者第一资源为第三资源的子集)的情况下,PRACH机会为有效(valid);所述第三资源为:配置给MT部分的资源;所述第一资源为:MT部分的PRACH机会对应的资源。
这种情况下,确定的MT部分的PRACH发送机会所对应的资源位于配置给MT部分的资源之内,因此MT部分的PRACH机会为有效,MT部分可以利用这部分资源进行PRACH的发送。
准则3
如图6c所示,第一资源位于第四资源之内(此之内可以理解为第一资源 与第四资源重叠,或者第一资源为第四资源的子集)的情况下,PRACH机会为有效;所述第四资源为:配置给DU部分的第一类型的资源;所述第一资源为:MT部分的PRACH机会对应的资源。
这种情况下,确定的MT部分的PRACH发送机会所对应的资源位于配置给DU部分的第一类型的资源之内。而对于第一类型的资源而言,MT部分具有更高的优先级,因此MT部分的PRACH机会为有效,MT部分可以利用这部分资源进行PRACH的发送。
准则4
如图6d所示,第一资源位于第五资源之内(此之内可以理解为第一资源与第五资源重叠,或者第一资源为第五资源的子集)的情况下,PRACH机会为有效;所述第五资源为:配置给MT部分的资源,且所述第五资源为配置给DU部分的第二类型的资源;所述第一资源为:MT部分的PRACH机会对应的资源;
这种情况下,确定的MT部分的PRACH发送机会所对应的资源位于配置给DU部分的第二类型的资源之内。虽然对于第二类型的资源而言,DU部分具有更高的优先级。但具备自回传能力的通信设备如果不接入到具有光纤传输能力的通信设备,本身也无法提供完整的服务,因此为了确保具备自回传能力的通信设备能够接入到具有光纤传输能力的通信设备,此时也确定MT部分的PRACH机会为有效,MT部分可以利用这部分资源进行PRACH的发送。
以上对MT部分的PRACH发送机会的有效性进行了判断,下面进一步对DU部分的PRACH接收机会的有效性判断准则做进一步详细说明。
准则5
如图6e所示,第二资源位于第六资源之内(此之内可以理解为第一资源与第六资源重叠,或者第一资源为第六资源的子集)的情况下,PRACH机会为有效;所述第六资源为:配置给DU部分的第二类型的资源;所述第二资源为:DU部分的PRACH机会对应的资源。
这种情况下,确定的DU部分的PRACH接收机会所对应的资源位于配置给DU部分的第二类型的资源之内。而对于第二类型的资源而言,DU部分 具有更高的优先级,因此,此时也确定DU部分的PRACH机会为有效,DU部分可以利用这部分资源进行PRACH的接收。
准则6
如图6f所示,第二资源位于第七资源之内(此之内可以理解为第一资源与第七资源重叠,或者第一资源为第七资源的子集)的情况下,PRACH机会为无效;所述第七资源为:配置给DU部分的第一类型的资源;所述第二资源为:DU部分的PRACH机会对应的资源。
这种情况下,确定的DU部分的PRACH接收机会所对应的资源位于配置给DU部分的第一类型的资源之内。而对于第一类型的资源而言,MT部分具有更高的优先级,因此,无论这部分资源MT部分有没有使用,均确定DU部分的PRACH机会为无效,DU部分不能利用这部分资源进行PRACH的接收,以确保MT部分对这部分资源的优先使用权。
准则7
如图6g所示,第二资源位于第八资源之内(此之内可以理解为第一资源与第八资源重叠,或者第一资源为第八资源的子集)的情况下,PRACH机会为无效;所述第八资源为:DU部分的不可用资源;所述第二资源为:DU部分的PRACH机会对应的资源。
这种情况下,确定的DU部分的PRACH接收机会所对应的资源为配置给DU部分的不可用资源,因此可以确定DU部分的PRACH机会为无效,DU部分不能利用这部分资源进行PRACH的接收。
准则8
本公开具体实施例中,之前提到,当MT部分的PRACH机会对应的传输资源位于配置给DU部分的第一类型的资源或第二类型的资源之内时,为了保证具备自回传能力的通信设备能够接入到具有光纤传输能力的通信设备,对应的MT部分的PRACH机会均为有效,对应的,这部分资源对DU部分不可用,即:
第一资源位于第九资源之内的情况下,所述第九资源对DU部分不可用;所述第九资源为:配置给DU部分的第一类型的资源或第二类型的资源;所述第一资源为:MT部分的PRACH机会对应的资源。
<MT部分和DU部分工作于频分模式或空分模式>
当MT部分和DU部分工作于频分模式或空分模式时,MT部分和DU部分在同一时间可以共享时域资源,此时可以根据如下准则中的至少一个,确定PRACH机会有效和/或无效,和/或确定可用于传输的资源。
准则9
如图6h所示,第一资源位于第十资源之内(此之内可以理解为第一资源与第十资源重叠,或者第一资源为第十资源的子集)的情况下,PRACH机会为有效;所述第十资源为:配置给DU部分的第一类型的资源;所述第一资源为:MT部分的PRACH机会对应的资源。
这种情况下,确定的MT部分的PRACH发送机会所对应的资源位于配置给DU部分的第一类型的资源之内。而对于第一类型的资源而言,MT部分具有更高的优先级,因此MT部分的PRACH机会为有效,MT部分可以利用这部分资源进行PRACH的发送。
准则10
如图6i所示,第二资源位于第十一资源之内(此之内可以理解为第一资源与第十一资源重叠,或者第一资源为第十一资源的子集)的情况下,PRACH机会为有效;所述第十一资源为:配置给MT部分,且资源方向为下行或灵活的资源;或者,所述第十一资源为:配置给MT部分,但所述MT部分没有使用的资源;所述第二资源为:DU部分的PRACH机会对应的资源,且所述第二资源为第一类型的资源。
这种情况下,确定的DU部分的PRACH接收机会所对应的软资源虽然已经配置给MT部分,但由于配置MT部分的资源的资源方向为下行或灵活的资源,即可以执行接收操作。而对于DU部分的PRACH机会也是接收机会,由于具有回传链路和接入链路的网络设备,在频分或者空分模式下,其可以同时执行接收动作或者同时执行发送动作。因此,DU部分的PRACH机会有效,DU部分可以利用这部分资源进行PRACH的接收。
另外一种情况下,确定的DU部分的PRACH接收机会所对应的软资源虽然已经配置给MT部分,但MT部分并未使用,因此,DU部分的PRACH机会为有效,利用这部分资源进行PRACH的发送。
准则11
如图6j所示,第二资源位于第十二资源之内(此之内可以理解为第一资源与第十二资源重叠,或者第一资源为第十二资源的子集)的情况下,PRACH机会为有效;所述第十二资源为:没有配置给MT部分,但配置给DU部分的资源;所述第二资源为:DU部分的PRACH机会对应的资源。
这种情况下,确定的DU部分的PRACH接收机会所对应的资源并没有配置给MT部分,但已经配置给DU部分(可以是软资源,也可以是硬资源),因此,DU部分的PRACH机会有效,DU部分可以利用这部分资源进行PRACH的接收。
准则12
如图6k所示,第二资源位于第十三资源之内(此之内可以理解为第一资源与第十三资源重叠,或者第一资源为第十三资源的子集)的情况下,PRACH机会非有效(或者说,PRACH机会为无效);所述第十三资源为:配置给MT部分,且资源方向为上行的资源;所述第二资源为:DU部分的PRACH机会对应的资源,且所述第二资源为第一类型的资源。
这种情况下,确定的DU部分的PRACH接收机会所对应的软资源已经配置给MT部分,且由于配置MT部分的资源的资源方向为上行,即可以执行发送操作。而对于DU部分的PRACH机会是接收机会,由于具有回传链路和接入链路的网络设备,在频分或者空分模式下,其不能同时执行接收动作和发送动作。因此,DU部分的PRACH机会无效,DU部分不可以利用这部分资源进行PRACH的接收。
准则13
第一资源位于第十四资源之内(此之内可以理解为第一资源与第十四资源重叠,或者第一资源为第十四资源的子集)的情况下,所述第十四资源对DU部分可用;所述第十四资源为:配置给DU部分,且资源方向为下行或灵活的第一类型的资源;所述第一资源为:MT部分的PRACH机会对应的资源。
这种情况下,确定的MT部分的PRACH发送机会所对应的资源位于配置给DU部分的第一类型的资源之内,且资源方向为下行或灵活,因此MT部分和DU部分是利用这部分资源都是执行发送操作。而由于具有回传链路 和接入链路的网络设备,在频分或者空分模式下,其可以同时执行发送动作。因此,所述第十四资源对所述DU部分可用。
准则14
第一资源位于第十五资源之内(此之内可以理解为第一资源与第十五资源重叠,或者第一资源为第十五资源的子集)的情况下,所述第十五资源对DU部分不可用;所述第十五资源为:配置给DU部分,且资源方向为上行的第一类型的资源;所述第一资源为:MT部分的PRACH机会对应的资源。
这种情况下,与准则13相反,虽然确定的MT部分的PRACH发送机会所对应的资源位于配置给DU部分的第一类型的资源之内,但由于资源方向为上行,且由于具有回传链路和接入链路的网络设备,在频分或者空分模式下,不能可以同时执行发送和接收动作,因此,所述第十五资源对DU部分不可用。
准则15
第二资源位于第十六资源之内(此之内可以理解为第一资源与第十六资源重叠,或者第一资源为第十六资源的子集)的情况下,所述第二资源对DU部分可用;所述第十六资源为:配置给MT部分,且资源方向为下行或灵活的资源;或者,所述第十六资源为:没有被配置给MT部分的资源;所述第二资源为:DU部分的PRACH机会对应的资源,且配置给DU使用的资源。
这种情况下,确定的DU部分的PRACH接收机会所对应的软资源虽然已经配置给MT部分,但由于配置MT部分的资源的资源方向为下行或灵活的资源,即可以执行接收操作。而对于DU部分的PRACH机会也是接收机会,由于具有回传链路和接入链路的网络设备,在频分或者空分模式下,其可以同时执行接收动作或者同时执行发送动作。因此,DU部分可以利用所述第二资源。
另外一种情况下,确定的DU部分的PRACH接收机会所对应的软资源并没有配置给MT部分,因此,DU部分可以利用所述第二资源。
准则16
第二资源位于第十七资源之内(此之内可以理解为第一资源与第十七资源重叠,或者第一资源为第十七资源的子集)的情况下,所述第二资源对DU 部分不可用;所述第十七资源为:配置给MT部分,且资源方向为上行的资源;所述第二资源为:DU部分的PRACH机会对应的资源,且所述第二资源为第一类型的资源。
这种情况下,同样由于具有回传链路和接入链路的网络设备,在频分或者空分模式下,不能可以同时执行发送和接收动作。因此,所述第二资源对DU部分不可用。
需说明的是,通过本公开实施例的方法判断出的PRACH机会有效和/或无效仅是一个中间结果,在此基础上,还需要进一步结合相关技术中的PRACH机会的有效性判断准则来进一步判断,如根据上下行的时隙配置(TDD-UL-DL-ConfigurationCommon)、上行符号位置信息(是否在UL符号内),SS/PBCH块的位置、下行符号的处理时延、PRACH机会与下行符号的位置关系等来进一步判断。
如一种判断准则为:在如下两个条件满足时才最终确定PRACH机会有效:
1、PRACH机会位于上行符号内;
2、没有落在PRACH时隙的SS/PBCH块之前,且PRACH机会的起点与最后一个下行符号以及SS/PBCH块传输符号的最后一个符号之间的距离大于或等于N(由表8.1-2定义)个符号。
