Definitions
- the present invention relates to communication technologies, and in particular, to a scheduling method and device.
- Relaying technology is introduced in 4G LTE systems. Reach the data between the base station (English name: Base station, English abbreviation: BS) and the terminal device through the relay node (English name: relay node, English abbreviation: RN) deployed in the network, thereby achieving enhanced network capacity and solving coverage.
- the purpose of the blind spot Due to the half-duplex constraint of the RF device, the relay node cannot receive at the same time when transmitting data, and cannot transmit at the same time when receiving data.
- the collision of the transmission of the signal and the reception of the signal may be referred to as a transmission and reception collision.
- the RN node backhaul link and the access link cannot be transmitted simultaneously.
- the link between the donor base station (English name: Donor eNB (evolved node B), English abbreviation: DeNB) and the relay node may be referred to as a backhaul link, and the link between the relay node and the UE. It can be called an access link.
- the DeNB transmits a signal (ie, a downlink signal of a backhaul link) to a RN in a subframe of a predetermined multicast single frequency network (English name: MBSFN), in which the eNB is in the subframe.
- the RN transmits the signal in the uplink subframe of one RN (ie, the uplink signal of the backhaul link) to the DeNB, in which the RN does not schedule the uplink data of the access link, so You can avoid sending and receiving conflicts.
- the downlink and uplink transmissions of the backhaul link reach the purpose of exclusive resources, and the collision of the transmission and reception of the backhaul link and the access link is avoided.
- This technical solution is a way to reserve resources to avoid sending and receiving conflicts. Specifically, even if the backhaul link does not transmit or does not occupy all resources, its unoccupied resources cannot be used by the access link.
- NR new wireless
- NR introduces the integration of access and backhaul (English full name: Integrated Access and Backhaul, IAB) technology, IAB technology needs to be more flexible to support the resource allocation of access links and backhaul links.

Description
本申请要求于2017年11月23日提交中国国家知识产权局、申请号为CN201711185048.4、发明名称为“一种调度的方法及设备”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。
本发明涉及通信技术,尤其涉及一种调度的方法及设备。
在4G LTE系统中引入中继(relaying)技术。通过在网络中部署的中继节点(英文全称:relay node,英文简称:RN)转发基站(英文全称:Base station,英文简称:BS)和终端设备间的数据,从而达到增强网络容量,解决覆盖盲区的目的。由于射频器件的半双工约束,中继节点在进行数据的发送时无法同时进行接收,在进行数据的接收时无法同时进行发送。信号的发送和信号的接收的冲突可以称为收发冲突。为了避免收发冲突,在LTE的Relaying方案中,RN节点回传链路和接入链路不能同时进行传输。其中,供体基站(英文全称:Donor eNB(evolved node B),英文简称:DeNB)和中继节点之间的链路可以被称为回传链路,中继节点和UE之间的链路可以被称为接入链路。DeNB在一个预定的多播组播单频网(英文全称:multicast broadcast single frequency network,英文简称:MBSFN)子帧中传输信号(即回传链路的下行信号)到RN,在这个子帧中没有接入链路的信号传输;RN在一个RN的上行子帧传输信号(即回传链路的上行信号)到DeNB,在这个子帧中RN不会调度接入链路的上行数据,因此可以避免收发冲突。通过这套机制,回传链路的下行和上行传输都达到了独占资源的目的,避免了回传链路和接入链路的收发冲突。这种技术方案是一种预留资源避免收发冲突的方式,具体地说,即便回传链路没有进行传输或者未占用所有的资源,其未占用的资源也无法被接入链路使用。
新无线(英文全称:new radio,英文简称:NR)系统也会支持中继技术。NR引入了接入回传一体化(英文全称:Integrated Access and Backhaul,英文简称:IAB)技术,IAB技术需要更加灵活的支持接入链路和回传链路的资源分配。在NR系统中,需要提供一种调度回传链路的方法,可以支持灵活的接入链路和回传链路的资源分配。

下边结合附图,对本发明实施例进行详细的说明。
实施例一
图4为本发明实施例提供的一种调度方法示意流程图。参见图4,该方法应用于图1所示的通信系统中,该方法包括:
步骤401、第一设备确定传输时间差信息。
该传输时间差为第一链路的控制信道和该第一链路的控制信道所调度的第一链路的数据信道之间的时间差。该传输时间差,可以是第一链路中控制信道传输的开始时刻跟该控制信道调度的第一链路数据信道传输的开始时刻间的差值,或者是第一链路中控制信道传输的结束时刻跟该控制信道调度的第一链路数据信道传输的结束时刻间的差值。或者,该传输时间差,也可以是是第一链路中控制信道传输的结束时刻跟该控制信道调度的第一链路数据信道传输的开始时刻间的差值,或者其他表示第一链路中控制信道传输和该控制信道调度的第一链路数据信道传输的时间的差值。传输时间差的值的单位,可以为帧,子帧,时隙,或者符号等,这里不限定。
可选的,传输时间差的信息可以包括如下至少一种信息:传输时间差的值N的信息;所述传输时间差大于等于M的信息;所述传输时间差小于等于K的信息。
或者说,传输时间差信息包括如下至少一种传输时间差信息。
传输时间差信息(1):传输时间差的值N的信息;
其中,对于调度灵活性没有很高的要求的场景,可以采用半静态的方式传输时间差信息(1),该传输时间差信息可以为一个具体的数值,比如N的值的信息。
传输时间差信息(2):所述传输时间差大于等于M的信息;或者,所述传输时间差大于M的信息;
传输时间差信息(3):所述传输时间差小于等于K的信息;或者,所述传输时间差 小于K的信息;
对于传输时间差信息(2)或(3)的场景,第一设备通知给第二设备的传输时间差信息并不是一个确定的数值,而是指示所述传输时间差和M或K的关系。传输时间差信息(2)或(3)可以可以被用在对第二链路的调度中,例如用于判断是否进行第一链路和第二链路的空分复用调度。
传输时间差信息(4):所述传输时间差大于等于M的信息或者所述传输时间差大于M的信息,和传输时间差的值N的信息;
传输时间差信息(5):所述传输时间差小于等于K的信息或者所述传输时间差小于K的信息,和传输时间差的值N的信息。
在对调度灵活度要求高的场景,可以采用传输时间差信息(4)或(5)。第二设备在收到第一消息后,可以将其中,N大于等于0。可选的,N的值可以由第一设备根据第二设备的处理时延信息确定。
本申请中的处理时延,可以是第二设备从接收到所述第一链路的控制信道到完成第二链路的调度之间的时间。
M、K大于等于0。可选的,M的值大于等于第二设备的处理时延,比如M的值为大于或等于第二设备的处理时延的最小的一个整数。M的值可以由第一设备根据第二设备的处理时延信息确定。可选的,K的值大于等于第二设备的处理时延,比如K的值为小于或等于第二设备的处理时延的最小的一个整数。K的值可以由第一设备根据第二设备的处理时延信息确定。
其中,N、M、K的单位可以是时隙、迷你时隙、子帧、帧或者ofdm符号等。
传输时间差信息(4)或(5)这两种情况下,第一设备通过两个信息完成了对传输时间差信息的指示。首先第一设备指示所述传输时间差和M或K的关系,第二设备在收到第一个信息发送的所述传输时间差和M或K的关系之后,可以根据该信息对第二链路进行调度;然后第二设备根据具体的时间差的取值N的信息,则可以确定第一链路数据信道具体的调度位置。
可选的,第二设备发送的该第二设备的处理时延信息给第一设备,第一设备接收该第二设备的的处理时延信息,第一设备根据接收的第二设备的处理时延信息确定传输时间差信息。
步骤402、第一设备发送所述传输时间差的信息给第二设备。
可选的,第一设备可以通过如下至少一种方式发送所述传输时间差的信息给第二设备。
发送方式(1):第一设备可以通过高层信令,比如无线资源控制(英文全称:Radio Resource Control,英文缩写:RRC)信令或媒体接入控制层控制单元(英文全称:Media Access Control-control element;英文简称:MAC-CE),或者物理层信令,比如下行控制信息(英文全称:Downlink Control Information,英文简称:DCI),向第二设备发送传输时间差信息(1)。
发送方式(2):第一设备通过高层信令,比如RRC信令或MAC-CE,向第二设备发送传输时间差信息(2)或(3)。
发送方式(3):第一设备通过高层信令,比如RRC信令或MAC-CE,向第二设备 发送如下信息:所述传输时间差大于等于M的信息或者所述传输时间差大于M的信息;然后,第一设备通过物理层信令,比如DCI,向第二设备发送传输时间差的值N的信息。
发送方式(4):第一设备通过高层信令,比如RRC信令或MAC-CE,向第二设备发送如下信息:所述传输时间差小于等于K的信息或者所述传输时间差小于K的信息;然后,第一设备通过物理层信令,比如DCI,向第二设备发送传输时间差的值N的信息。
步骤403、第二设备接收第一设备发送的传输时间差信息,并根据该传输时间差信息进行调度。
与步骤402对应,第二设备接收第一设备采用前述的四种发送方式中的任一种发送方式发送的传输时间差信息。
第二设备采用如下至少一种接收方式接收第一设备通过发送的所述传输时间差信息:
接收方式(1):所述第二设备接收所述第一设备通过高层信令或者物理层信令发送的所述传输时间差信息(1);
接收方式(2):所述第二设备接收通所述第一设备过高层信令发送的所述传输时间差信息(2)或(3);
接收方式(3):所述第二设备接收所述第一设备通过高层信令发送的如下信息:所述传输时间差大于等于M的信息或者所述传输时间差大于M的信息;所述第二设备接收所述第一设备通过物理层信令发送的所述传输时间差的值N的信息;
接收方式(4):所述第一设备接收所述第二设备通过高层信令发送的如下信息:所述传输时间差小于等于K的信息或者所述传输时间差小于K的信息;所述第一设备接收所述第二设备通过物理层信令发送的所述传输时间差的值N的信息。
第二设备根据该传输时间差信息进行调度包括:第二设备根据该传输时间差信息确定是否需要给第一链路的数据信道预留资源,和/或第二设备根据该传输时间差信息调度第二链路。
可选的,第二设备根据该传输时间确定是否需要给第一链路的数据信道预留资源包括如下第一组调度方式中任一种方式:
调度方式(1):当传输时间差的信息包括传输时间差信息(1)时,如果所述传输时间差值N大于所述第二设备的处理时延,第二设备不为第一链路的数据信道预留资源;可选的,第二设备根据所述传输时间差值N,在所述第一链路的数据信道上与所述第一设备进行通信。也就是,第二设备根据所述传输时间差值N确定第一链路的数据信道的位置。
调度方式(2):当传输时间差的信息包括传输时间差信息(1)时,如果所述传输时间差值N小于等于所述第二设备的处理时延,第二设备为第一链路的数据信道预留资源。可选的,第二设备根据所述传输时间差值N,在所述第一链路的数据信道上与所述第一设备进行通信。也就是,第二设备根据所述传输时间差值N确定第一链路的数据信道的位置。
调度方式(3):当传输时间差的信息包括传输时间差信息(2)或(4)时,第二设备不为第一链路的数据信道预留资源。可选的,当传输时间差的信息包括传输时间差信息(4)时,第二设备根据所述传输时间差值N,在所述第一链路的数据信道上与所述 第一设备进行通信。也就是,第二设备根据所述传输时间差值N确定第一链路的数据信道的位置。
调度方式(4):当传输时间差的信息包括传输时间差信息(3)或(5)时,第二设备为第一链路的数据信道预留资源。可选的,当传输时间差的信息包括传输时间差信息(5)时,第二设备根据所述传输时间差值N,在所述第一链路的数据信道上与所述第一设备进行通信。也就是,第二设备根据所述传输时间差值N确定第一链路的数据信道的位置。
可选的,在上述四种调度方式中,如果第二设备需要预留资源,本发明实施例中的方法可以包括:第一设备通知第二设备预留资源的信息,第二设备接收预留资源的信息,并预留该预留资源。预留资源的信息包括:预留资源的带宽信息和/或占用的ofdm符号数等。
第二设备调度第二链路包括如下第二组调度方式中任一种方式:
调度方式(5):如果第二设备为第一链路的数据信道预留资源,第二设备在该预留资源以外的资源上调度第二链路。可选的,在动态TDD模式下,第一链路的数据信道占用的资源和第二链路的数据信道占用的资源是空分复用的。
调度方式(6):如果第二设备不为第一链路的数据信道预留资源,第二设备可以动态调度第二链路。可选的,所述第一链路的数据信道占用的资源和所述第二链路的数据信道占用的资源是时分、频分或者空分复用。
本发明实施例中,第一设备把传输时间差信息发给第二设备,第二设备可以根据传输时间差信息进行调度,从而保证了调度的灵活性。第二设备根据传输时间差信息,判断是否需要为第一链路的数据信道预留资源,如果需要预留资源,第二设备可以在预留资源以外的其他资源上对第二链路进行调度;如果不需要预留资源,第二设备可以对第二链路进行动态调度,从而使第一链路的数据信道和第二链路的数据信道进行时分、频分或空分的复用。
下边结合图5a和图5b所示回传链路的调度示意图,说明本实施例的有益效果。其中以第一设备为DgNB,第二设备为rTRP,第一链路为回传链路为例说明。在图5a中,如果回传控制信道对回传数据信道的调度发生在同一个时间单元内,那么在有限的信号处理能力下,rTRP接收完回传控制信道后,才能知道回传数据信道是否被调度,以及调度在哪些资源位置上。如图5a所示的情况2和3中,如果回传数据信道未被调度,或者回传数据信道未将资源占用完,如果第一设备未通知第二设备传输时间差信息,第二设备就不能根据传输时间差信息进行调度,也就是回传数据信道未用的资源将无法被重新用于接入链路的数据传输。在图5b中所示的情况1中,时隙n+1被调度给接入链路数据信道,时隙n+2被调度给回传链路数据信道使用。而在情况2中,如果时隙n+2未被调度给回传数据信道使用,第一设备通知第二设备传输时间差信息,第二设备就能根据传输时间差信息进行调度,也就是时隙n+2就将可以被调度给接入链路的数据信道使用。
实施例二
图6为本发明实施例提供的一种调度方法示意流程图。参见图6,该方法应用于图1所示的通信系统中,该方法包括:
步骤601、第一设备确定第一链路控制信道的配置信息。
所述第一链路控制信道的配置信息包括:所述第一链路控制信道占用的时域资源的信息。可选的,所述第一链路控制信道的配置信息还可以包括所述第一链路控制信道占用的频域资源的信息。
可选的,所述第一链路控制信道占用的时频资源与第二链路控制信道占用的时频资源重叠或部分重叠。也就是,第一链路控制信道和第二链路控制信道所在控制资源集合(英文全称:Control Resource Set,英文简称:CORESET)属于同一控制资源集合的子集。控制资源集合可以包括时域资源集合和/频域资源集合。同一控制资源集合既可以发送用于第一链路的控制信道,也可以发送用于第二链路的控制信道。比如,第一链路的控制信道是一个CORESET可以是一个时隙的第一个OFDM符号开始,并持续1,2或者3个OFDM符号;第二链路的控制信道是这个CORESET可以是一个时隙的其他几个符号。比如图7a所示的调度示意图。其中以第一设备为DgNB,第二设备为rTRP,第一链路为回传链路,第二链路为接入链路为例说明。在图7a中,在同一控制信道中调度回传链路的数据信道和接入链路的数据信道,也就是,回传链路的控制信道和接入链路的控制信道的资源集合相同,回传链路的控制信道和接入链路的控制信道是同一个控制信道。
可选的,也可以预先定义控制资源集合,该控制资源集合表示下行控制信道所占用的资源的集合。所述第一链路控制信道占用的时频资源与第二链路控制信道占用的时频资源可以为该控制资源集合中的子集。如果预先定义第一链路控制信道占用的时频资源集合,第一设备可以不用向第二设备通知预先定义第一链路控制信道占用的时频资源集合,第二设备在该预先定义的时频资源集合中通过盲检第一链路的控制信道。
可选的,所述第一链路控制信道占用的时频资源与第二链路控制信道占用的时频资源是时分复用的。也就是,可以通过配置信息使第一链路的控制信道所在的CORESET和第二链路的控制信道所在的CORESET时分复用,可以使第二设备在同一时间单元中,既能接收第一链路的控制信道,又可以发送第二链路的控制信道。比如图7b所示的调度示意图。其中以第一设备为DgNB,第二设备为rTRP,第一链路为回传链路,第二链路为接入链路为例说明。在图7b中,rTRP在PDCCH(发送),也就是接入链路的控制信道,和PDCCH(接收),也就是回传链路的控制信道进行时分复用。
其中,以一个时隙内所述第一链路控制信道占用的时频资源与第二链路控制信道占用的时频资源是时分复用为例说明时分复用的具体配置方案。总体上,在一个时隙的头部,第二设备首先发送第二链路控制信道,随后经过一个保护间隔,再接收第一链路控制信道。但是,由于需要一个符号作为第二设备的收发切换保护间隔,而收发保护间隔不能和DMRS冲突。因此,当该时隙存在下行DMRS时,第一链路控制信道开始于该时隙中最后一个DMRS符号之后的第二个符号上,且该时隙中最后一个DMRS符号之后的第一个OFDM符号为保护间隔。当该时隙不存在下行DMRS时,第一链路控制信道开始于第二链路控制信道的最后一个OFDM符号之后的第二个OFDM符号,且第二链路控制信道的最后一个OFDM符号之后的第一个OFDM符号为保护间隔。以图8为例进行说明。在图8中,其中以第一设备为DgNB,第二设备为rTRP,第一链路为回传链路,第二链路为接入链路为例说明。给出的是接入控制信道占用2个OFDM符号, DMRS占用1个符号、2个符号或者不存在DMRS时的保护间隔和回传控制信道第一个OFDM符号所在的位置的示意图。其中S0,S1,S2,S3,S4,S5等分别表示符号0,1,2,3,4,5。
为了达到这种配置的协调,第二设备需要向第一设备上报第二链路控制信道和DMRS所占用的OFDM符号数,第一设备根据该上报信息决定第一链路控制信道的位置;或者,第一链路控制信道的位置也可以由第一设备决定通知第二设备,第二设备按照第一链路控制信道的位置来决定第二链路的接入控制信道和下行DMRS的符号数量。
可选的,所述第一链路控制信道的配置信息可以包括非周期性的第一链路控制信道的配置信息,和/或者周期性的第一链路控制信道的配置信息。
非周期性的第一链路控制信道的配置信息可以适用于突发的对时延较敏感的回传数据传输。
非周期性的第一链路控制信道的配置信息可以包括:所述第一链路控制信道占用的时域资源的位置信息。比如,该配置信息可以指示第一链路控制信道将在收到该配置信息后的第L个时隙发送,可选地,也可以指示第一链路控制信道将多次发送,并且指示每一次发送的时间资源;或者,也可以指示在一个时隙中,第一链路控制信道占用的ofdm符号的索引等。可选,非周期性的第一链路控制信道的配置信息可以包括:所述第一链路控制信道占用的频域资源的信息。例如,所述第一链路控制信道可以位于一个时隙的头部的若干个OFDM符号上,且占用部分或全部的带宽。
周期性的第一链路控制信道的配置信息可以包括:所述第一链路控制信道的传输周期的信息。也就是,所述第一链路控制信道占用的时域资源的信息包括所述第一链路控制信道的传输周期的信息。所述第一链路控制信道的传输周期的信息包括B个时间单元,B为大于等于1的整数。所述第一链路控制信道的传输周期可以为1个时隙。比如,在某些情况下(例如回传链路的容量需求很大,或者回传链路对时延要求很高),第一设备可以将第一链路控制信道的周期配置为1个时隙。
可选的,周期性的第一链路控制信道的配置信息还可以包括:所述第一链路控制信道的传输周期的偏移量信息。偏移量的单位为帧、子帧、时隙或迷你时隙。
以图9为例进行说明。在图9中,其中以第一设备为DgNB,第二设备为rTRP,第一链路为回传链路,第二链路为接入链路为例说明。假设DgNB为rTRP配置的周期为X个时隙,偏移量为Y个时隙,假设时隙的编号为n,则rTRP需要在满足以下条件的时隙n中去监听回传控制信道:Mod(n,X)=Y;
Mod表示求模操作或取余数操作。对于TDD模式,满足上式的n也有可能是上行时隙或者没有配置下行控制信道,此时rTRP可以在n之后的第一个配置了下行控制信道的时隙中去监听回传控制信道。
可选地,第二设备也可以被配置多个周期和多个偏移量,第二设备在每个第一设备对应的第一链路控制信道配置信息对应的第一链路控制信道上去监听该第一设备的回传控制信道。
步骤602、第一设备发送第一链路控制信道的配置信息给第二设备,第二设备接收第一设备发送的第一链路控制信道的配置信息。
第一设备通过RRC信令,向第二设备发送周期性的第一链路控制信道的配置信息。 第二设备接收第二设备通过RRC信令发送的周期性的第一链路控制信道的配置信息。
第一设备通过DCI或者MAC-CE,向第二设备发送非周期性的第一链路控制信道的配置信息。第二设备接收第二设备通过DCI或者MAC-CE发送的非周期性的第一链路控制信道的配置信息。
步骤603、第一设备在第一链路控制信道上向第二设备发送第一链路的控制信息。
步骤604、第二设备在确定第一链路的控制信道上监听第一设备发送的第一链路的控制信息。
第二设备根据接收到的第一链路控制信道的配置信息确定第一链路的控制信道。
如果第二设备接收到周期性的第一链路控制信道的配置信息,第二设备可以根据Mod(n,X)=Y确定第一链路的控制信道。其中,X为所述第一链路控制信道的传输周期,Y为所述第一链路控制信道的传输周期的偏移量,n为在一个时间单元内,所述第一链路控制信道占用的时域资源的位置编号,比如时隙编号,或者符号编号。
可选的,本实施例进一步包括:第一设备向第二设备发送指示信息,该指示信息用于指示第二设备激活或关闭第一链路控制信道的配置信息。该指示信息可以通过高层信令由第一设备发给第二设备。如果第一链路控制信道的配置信息被关闭,第二设备监听所有的控制信道。
可选的,如果第二设备没有收到第一设备发送的第一链路控制信道的配置信息,第二设备监听所有的控制信道。
本发明实施例中,第一设备通知第二设备第一链路控制信道的配置信息,第二设备根据该配置信息确定第一链路的控制信道,在第一链路控制信道接收控制信息,从而实现第一链路的灵活调度。
