Definitions

  • the present application relates to the field of mobile communications, and in particular, to a transmission resource allocation method, a data transmission method, and an apparatus.
  • the existing uplink scheduling mechanism of LTE mainly includes two types: dynamic scheduling and semi-persistent scheduling.
  • the semi-persistent scheduling is mainly applied to the periodic service, that is, the data packets of the terminal device arrive at a certain period (for example, VoIP service), and the network device reserves the time-frequency resource to send the uplink data to the terminal device in a relatively fixed manner.
  • the method can reduce the overhead of scheduling signaling.
  • the period of semi-persistent scheduling is configured by higher layer signaling, and the activation and release of semi-persistent scheduling is based on physical layer signaling.
  • Dynamic scheduling is the most common scheduling method for uplinks. The flow of a typical dynamic uplink scheduling is as follows:
  • a resource request is sent to the network device, and the resource request may be a dedicated scheduling request (SR) or a random access sequence (Physical Random Access CHannel, PRACH);
  • SR dedicated scheduling request
  • PRACH Physical Random Access CHannel
  • the network device After receiving the resource request of the terminal device, the network device allocates a time-frequency resource to the terminal device, and sends an uplink scheduling instruction (UL grant) to the terminal device;
  • UL grant uplink scheduling instruction
  • the terminal device After receiving the uplink scheduling instruction, the terminal device starts to prepare packet data (code value adjustment), and the data packet header may include a Buffer Status Report (BSR) of the terminal device;
  • BSR Buffer Status Report
  • the network device receives the uplink data packet of the terminal device at a specified time, and performs demodulation and decoding.
  • the transmission from the data packet to the uplink data transmission mainly includes two parts of delay: the first part is a delay from when the terminal device sends a scheduling request to when the terminal device receives the uplink scheduling instruction;
  • the second part is the delay from when the terminal device receives the uplink scheduling command to the terminal device to send data.
  • the main reasons for the delay of the two parts are the processing delay of the network device and the terminal device and the transmission delay of the air interface signal. In the existing LTE system, the above two-part delay is 4 ms.
  • a major feature of the 5G communication system compared to the 4G communication system is the addition of support for ultra-reliable low-latency services (URLLC).
  • URLLC ultra-reliable low-latency services
  • Typical use cases include industrial control, industrial production process automation, human-computer interaction and telemedicine.
  • URLLC services There are two types of URLLC services: one is periodic service, the arrival of data packets is periodic, and the service can adopt semi-persistent scheduling; the other is sporadic service, and the arrival of data packets cannot be predicted.
  • the service is not suitable for semi-persistent scheduling, and the adoption of grant based in LTE also brings delay to packet transmission.
  • the grant-free uplink transmission method reduces the physical layer processing and transmission delay of the data packet while reducing the physical layer processing and transmission delay of the data packet by omitting the uplink resource request of the terminal device and the downlink scheduling instruction transmission procedure of the network device.
  • the overhead of signaling has become a candidate for URLLC uplink transmission.
  • the non-scheduling instruction mechanism is not completely controlled by the network device, it is easy to cause interference between the terminal devices, resulting in low detection accuracy.

Description

一种传输资源分配方法、数据发送方法及装置
本申请要求于2017年5月5日提交中国专利局、申请号为201710313511.2、申请名称为“一种传输资源分配方法、数据发送方法及装置”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
本申请涉及移动通信领域,尤其涉及一种传输资源分配方法、数据发送方法及装置。
背景技术
现有的LTE的上行调度机制主要包括两种:动态调度(dynamic scheduling)和半持续调度(semi-persistent scheduling)。半持续调度主要适用于周期性的业务,即终端设备的数据包以一定的周期到达(例如VoIP业务),网络设备以相对固定的方式给终端设备预留时频资源发送上行数据,这种调度方式可以减少调度信令的开销。半持续调度的周期通过高层信令的配置,半持续调度的激活和释放基于物理层信令。动态调度是上行最常见的调度方式。一个典型的动态上行调度的流程如下:
1)终端设备数据包到达后,向网络设备发送一个资源请求,该资源请求可以是专用的调度请求(Scheduling Request,SR)或随机接入的前导序列(Physical Random Access CHannel,PRACH);
2)网络设备接收到终端设备的资源请求后,会为终端设备分配一块时频资源,并发送上行调度指令(UL grant)给该终端设备;
3)终端设备收到上行调度指令后,开始组包(编码调值)准备数据发送,数据包头可以包含终端设备的缓存状态信息(Buffer Status Report,BSR);
4)网络设备在指定时刻接收终端设备上行的数据包,进行解调译码。
由上可知,对于采用动态调度的终端设备,从数据包到达到上行数据发送主要包含了两部分的时延:第一部分是从终端设备发送调度请求到终端设备收到上行调度指令的时延;第二部分是从终端设备收到上行调度指令到终端设备发送数据的时延。产生这两部分时延的主要原因是网络设备和终端设备的处理时延和空口信号的发送时延。在现有的LTE系统中,上述的两部分时延均为4ms。
5G通信系统相比与4G通信系统的一大特征就是增加了对超可靠低时延业务(URLLC)的支持。URLLC的业务种类包括很多种,典型的用例包括工业控制,工业生产流程自动化,人机交互和远程医疗等。
URLLC业务的类型包括两种:一种是周期性的业务,数据包的到达是周期性的,这种业务可以采用半持续调度;一种是偶发性的业务,数据包的到达无法预测,这种业务不适合采用半持续调度,而采用LTE中的动态调度(grant based)也会给数据包传输带来时延。基于无调度指令(grant-free)的上行传输方式由于省略了终端设备的上行资源请求和网络设备的下行调度指令发送的步骤,所以在降低数据包的物理层处理和传输时延的同时也减少 了信令的开销,所以成为了URLLC上行传输的候选技术。
由于无调度指令机制不完全受网络设备控制,很容易造成终端设备间干扰,导致检测正确率低。

S203:所述网络设备向第一终端设备指示所述至少一个基本资源单元的资源位置和针对所述至少一个基本资源单元的导频配置。

S207:所述网络设备向所述第一终端设备指示所述基本资源单元中包括的最小调度单元的数量。
作为示例,所述基本资源单元中包括的最小调度单元的数量由RRC信令承载,该信令是用户专属的。
作为示例,所述基本资源单元中包括的最小调度单元的数量也可以是协议约定的,在这种情况下,所述网络设备无需向所述第一终端设备指示所述基本资源单元中包括的最小调度单元的数量。

S204:所述第一终端设备根据所述至少一个基本资源单元中的一个或更多个基本资源单元的资源位置确定传输资源。
作为示例,基本资源单元是最小的资源单元,实际传输时可以由P个基本资源单元组成资源单元来承载同一个传输块,P为正整数,根据传输块尺寸和MSC等级得到调制编码后所需要的资源单位(Resource Element,RE)数目,然后找到一个P,满足P个基本资源单元用于承载数据的RE数目最接近且大于或等于调制编码后所需要的RE数目。例如,一个32byte的URLLC包,其对应的传输块尺寸为256bit,配置了MCS为16QAM with coderate=0.5,则由上述计算方法可知,在一个基本资源单元在频域上包含2个PRB,在频域上包含1个时隙的情况下,每个传输块占用2个基本资源单元。

S206:所述第一终端设备根据针对所述一个或更多个基本资源单元的导频占用所述传 输资源发送数据。
可选地,本实施例还包括S208、S209、S210、S211、S212和S213。

这里,所述至少一个基本资源单元和所述一个以上基本资源单元均包括第一基本资源单元;针对所述至少一个基本资源单元的导频配置包括至少一个第一导频配置,所述至少一个第一导频配置是针对所述第一基本资源单元确定的;针对所述一个以上基本资源单元的导频配置包括至少一个第二导频配置,所述至少一个第二导频配置是针对所述第一基本资源单元确定的;每个第一导频配置与每个第二导频配置不同。
作为示例,所述网络设备向不同的终端设备指示的对应于同一基本资源单元的导频彼此不同,因此,多个终端设备在同一基本资源单元上进行数据发送,所述多个终端设备之间的导频也能保持正交。
例如,如表1所示,导频1、导频2和导频3是不同的导频,终端设备1、终端设备2、终端设备3和终端设备4是不同的终端设备,基本资源单元1、基本资源单元2和基本资源单元3是不同的基本资源单元,网络设备向终端设备1指示基本资源单元1对应的导频1、基本资源单元2对应的导频1和基本资源单元3对应的导频1,向终端设备2指示基本资源单元1对应的导频2和基本资源单元2对应的导频2,向终端设备3指示基本资源单元3对应的导频2,向终端设备4指示基本资源单元1对应的导频3和基本资源单元3对应的导频3,可以看出,终端设备1、终端设备2、终端设备3和终端设备4接收到的对应基本资源单元1的导频互不相同,终端设备1、终端设备2、终端设备3和终端设备4接收到的对应基本资源单元2的导频互不相同,终端设备1、终端设备2、终端设备3和终端设备4接收到的对应基本资源单元3的导频互不相同。

又例如,如表2所示,导频1、导频2和导频3是不同的导频,终端设备1、终端设备2、终端设备3和终端设备4是不同的终端设备,基本资源单元1、基本资源单元2和基本资源单元3是不同的基本资源单元,网络设备向终端设备1发送基本资源单元1对应的导频1、基本资源单元2对应的导频2和基本资源单元3对应的导频3,向终端设备2发送基本资源单元1对应的导频2和基本资源单元2对应的导频1,向终端设备3发送基本资源单元3对应的导频1,向终端设备4发送基本资源单元1对应的导频3和基本资源单元3对应 的导频2,可以看出,终端设备1、终端设备2、终端设备3和终端设备4接收到的对应基本资源单元1的导频互不相同,终端设备1、终端设备2、终端设备3和终端设备4接收到的对应基本资源单元2的导频互不相同,终端设备1、终端设备2、终端设备3和终端设备4接收到的对应基本资源单元3的导频互不相同。
Figure PCTCN2018085741-appb-000023
表2
也就是说,利用这种方案,网络设备可以选择向不同的终端设备发送不同的对应于该基本资源单元的导频,使得不同的终端设备在该基本资源单元上能够使用不同的导频发送数据,从而网络设备可以根据导频区分不同的终端设备。
S211:所述第二终端设备根据所述至少一个基本资源单元中的一个或更多个基本资源单元的资源位置确定传输资源。

本实施例中的各个步骤的先后顺序不限于如图2所示,所述步骤可以按照不同的顺序进行,也可以同时进行,例如,S203和S207可以通过所述网络设备发送给所述第一终端设备的一条信令实现,本申请对此不做限定。
在本实施例中,网络设备确定至少一个基本传输单元,且针对同一基本资源单元生成至少一个导频,即,实现了导频分段生成,并且共享时频资源的用户的分段长度一致,保证了分段导频正交性,正交的导频有利于网络设备识别用户和单链路的信道估计,因此,在无调度指令机制下,本实施例提供的方案能够提高检测正确率。
参照图3,本申请提供的传输资源分配方法的另一个实施例,包括S301、S302、S303、S304、S305和S306。
S301:网络设备确定至少一个基本资源单元,所述至少一个基本资源单元中的每个基本资源单元对应至少一个导频,所述至少一个基本资源单元中的第一基本资源单元对应至少两个导频,所述至少两个导频不同。
S302:所述网络设备针对所述至少一个基本资源单元中的每个基本资源单元确定至少一个导频配置。
S303:所述网络设备确定至少一个资源单元组,每个资源单元组包括至少一个资源单元,每个资源单元包括所述至少一个基本资源单元中的一个或更多个基本资源单元。
这里,所述至少一个资源单元组的资源位置可以是重叠的(即,所述至少一个资源单元组中的基本资源单元可以有部分或全部是相同的,也就是说,一个基本资源单元可以属 于不同的资源单元组),也可以是不重叠的(即,一个基本资源单元仅能属于一个基本单元组),本申请对此不做限定。
作为示例,所述网络设备将所述至少一个基本资源单元按照不同方式划分为不同的资源单元,按照每种方式划分的资源单元为一个资源单元组。例如,假设所述网络设备确定了8个基本资源单元,则所述网络设备可以确定包括1个基本资源单元的资源单元,这样的8个资源单元组成第一资源单元组,也可以确定包括2个基本资源单元的资源单元,这样的4个资源单元组成第二资源单元组。
S304:所述网络设备向终端设备指示所述至少一个资源单元组的资源位置和针对所述至少一个基本资源单元的导频配置。

作为示例,可以通过指示每个资源单元的频域起始位置为传输池中的第几个基本资源单元来指示这些资源单元的资源位置,这里,传输池是指所述网络设备向所述终端设备发送的导频对应的基本资源单元的集合。例如,对于组内的资源单元中包括1个基本资源单元的资源单元组,其资源单元的频域起始位置为传输池内的第n个基本资源单元,n=1,2,…,Z;对于组内的资源单元中包括2个基本资源单元的资源单元组,其资源单元的频域起始位置为传输池内的第m个基本资源单元,m=2,4,…,floor(Z/2)*2-1。
作为另一示例,可以通过指示每个资源单元组中的资源单元的频域起始位置为传输带宽内的最小调度单元(例如,PRB)的序号来指示这些资源单元的资源位置。例如,终端设备的传输带宽为20MHz,包含100个PRB,其中无调度指令资源池为1-10个PRB,基本资源单元的频域包含2个PRB,对于组内的资源单元中包括1个基本资源单元的资源单元组,其资源单元的频域起始位置为第n个PRB,n=1,3,5,7,9;对于组内的资源单元中包括2个基本资源单元的资源单元组,其资源单元的频域起始位置为第m个PRB,m=2,6。
作为示例,不同资源单元组的频域资源可以重叠,但组内的资源单元的起始位置集合不同。
作为示例,当某个资源单元组中包括多个资源单元时,所述终端设备从中随机选择一个或更多个资源单元进行本次传输,或者,终端设备根据预定义的跳频规则从中选择一个资源或更多个资源单元进行本次传输;当某个资源单元组包括一个资源单元时,终端设备在这个资源单元上进行本次传输。
可选地,在S304,所述网络设备向所述终端设备指示每个资源单元组的资源位置。
在这种情况下,可选地,在S304,所述网络设备向所述终端设备指示每个资源单元在所属的资源单元组中的位置。
或者,可选地,所述网络设备按照预定义规则(例如,跳频规则)确定每个资源单元在所属的资源单元组中的位置,所述终端设备按照所述预定义规则确定每个资源单元在所属的资源单元组中的位置。
作为示例,所述网络设备可以向所述终端设备指示所述预定义规则,或者,所述预定义规则也可以是协议约定的。
作为示例,所述网络设备向不同的终端设备指示的对应于同一基本资源单元的导频彼此不同。例如,如表3所示,导频1、导频2和导频3是不同的导频,终端设备1、终端设 备2和终端设备3是不同的终端设备,基本资源单元1、基本资源单元2和基本资源单元3是不同的基本资源单元,网络设备向终端设备1发送属于资源单元组1的基本资源单元3对应的导频1、属于资源单元组2的基本资源单元1对应的导频2和属于资源单元组2的基本资源单元2对应的导频2,向终端设备2发送属于资源单元组1的基本资源单元3对应的导频3、属于资源单元组2的基本资源单元1对应的导频1和属于资源单元组2的基本资源单元2对应的导频1,向终端设备3发送属于资源单元组1的基本资源单元3对应的导频2、属于资源单元组2的基本资源单元1对应的导频3和属于资源单元组2的基本资源单元2对应的导频3,可以看出,终端设备1、终端设备2和终端设备3接收到的对应基本资源单元1的导频互不相同,终端设备1、终端设备2和终端设备3接收到的对应基本资源单元2的导频互不相同,终端设备1、终端设备2和终端设备3接收到的对应基本资源单元3的导频互不相同。

表3
S305:所述终端设备根据所述至少一个资源单元组中的第一资源单元组中的资源单元的资源位置确定传输资源。
作为示例,在所述至少一个资源单元组为至少两个资源单元组的情况下,所述终端设备根据传输块尺寸和MSC等级得到调制编码后所需要的RE数目,然后从所述至少一个资源单元组中选择这样的资源单元组:该资源单元组内的资源单元中包括的基本资源单元用于承载数据的RE数目最接近且大于或等于调制编码后所需要的RE数目。
例如,一个32byte的URLLC包,其对应的传输块传输块尺寸1为256bit,一个50byte的URLLC包,其对应的传输块尺寸2为400bit,配置了MCS1为16QAM with coderate=0.4,MCS2为QPSK with coderate=0.4,本次传输对应传输块尺寸1和MCS1、传输块尺寸1和MCS2、传输块尺寸2和MCS1、传输块尺寸2和MCS2分别需要占用2、4、4、8个基本资源单元。如果当前URLLC包<传输块尺寸1,则当终端设备确定当前传输距离延时(latency)限还有重传机会,则采用MCS1和组内的资源单元包括2个基本资源单元的资源单元组,当终端设备确定当前传输距离延时限没有重传机会,则采用MCS2和组内的资源单元包括4个基本资源单元的资源单元组;如果当前URLLC包>传输块尺寸1,则当终端设备确定当前传输距离延时限还有重传机会,则采用MCS1和组内的资源单元包括4个基本资源单元的资源单元组,当终端设备发现当前传输距离延时限没有重传机会,则采用MCS2和组内的资源单元包括8个基本资源单元的资源单元组。
作为示例,当组内的资源单元所包括的基本资源单元数最多的资源单元组中的资源单元也无法承载一个URLLC包时,URLLC包可以拆分成多个传输块,在不同的时刻发送。
S306:所述终端设备根据针对所述第一资源单元组中的基本资源单元的导频配置确定针对所述第一资源单元组中的基本资源单元的导频。
S307:所述终端设备根据针对所述第一资源单元组中的基本资源单元的导频占用所述传输资源发送数据。
在本实施例中,每个资源单元组包括至少一个资源单元,每个资源单元包括至少一个基本资源单元,同一传输块由一个资源单元承载。
可选地,本实施例还包括S308。
S308:所述网络设备向所述终端设备指示每个资源单元组中的资源单元中包括的基本资源单元的数量。

可选地,本实施例还包括S309。
S309:所述网络设备向所述终端设备指示所述基本资源单元中包括的最小调度单元的数量。
在本实施例中,网络设备确定至少一个基本传输单元,且针对同一基本资源单元生成至少一个导频,即,实现了导频分段生成,并且共享时频资源的用户的分段长度一致,保证了分段导频正交性,正交的导频有利于网络设备识别用户和单链路的信道估计,因此,在无调度指令机制下,本实施例提供的方案能够提高检测正确率。
可选地,所述至少一个资源单元组中的每个资源单元组与传输参数对应。
可选地,本实施例还包括S310。
S310:所述网络设备向所述终端设备指示所述至少一个资源单元组与传输参数的对应关系。
作为示例,所述至少一个资源单元组与传输参数的对应关系也可以是协议约定的,在这种情况下,所述网络设备无需向所述终端设备指示所述至少一个资源单元组与传输参数的对应关系。
可选地,所述传输参数包括传输块尺寸和MSC等级中的至少一个。
作为示例,每个资源单元组对应一种传输块尺寸,终端选择与大于或等于且最接近当前需要传输的数据块的大小的传输块尺寸和对应的资源单元组发送数据。
作为另一示例,每个资源单元组对应一种MCS,终端选择与大于或等于且最接近当前需要传输需要的资源大小的资源单元组发送数据。
作为又一示例,每个资源单元组对应一种传输块尺寸和MCS的组合,例如,资源单元组1对应传输块尺寸1和MCS1的组合,资源单元组2对应传输块尺寸2和MSC1的组合,资源单元组3对应传输块尺寸1和MSC2的组合,资源单元组4对应传输块尺寸2和MSC2的组合;或者,每个资源单元组对应传输块尺寸和MCS的组合所需要的不同资源大小,例如资源单元组1对应传输块尺寸1和MCS1的组合,资源单元组2对应传输块尺寸2和MSC1的组合以及传输块尺寸1和MSC2的组合,资源单元3对应传输块尺寸2和MSC2的组合。
在每个资源单元组与传输参数对应的情况下,网络设备能够根据终端设备使用了哪个资源单元组来确定终端设备使用的传输参数,例如,在每个资源单元组对应一种传输块尺度的情况下,网络设备可根据终端设备使用的资源单元组来确定终端设备使用的传输块尺寸,通过这种方式,有助于网络设备对于终端设备使用的传输参数进行确定,降低了盲检 测复杂度。

关于本实施例中技术细节和有益效果的详细描述,应参照上述方法实施例。
参见图9,本申请提供的一种信道结构包括导频资源和数据资源,其中,数据资源包括分配给终端设备的数据资源和无调度资源池。纵向表示该信道结构的频域资源,横向表示该信道结构的时域资源。
这里,导频资源的频域宽度与数据传输资源的频域宽度不相关,网络设备单独配置导频占用的频域宽度,不同的终端设备的导频共享相同的时频资源。作为示例,导频占用的频域宽度可以与数据资源的频域宽度相同,也可以大于数据资源的频域宽度(如图12所示);导频占用的频域宽度可以与资源池(grant free)的频域宽度相同,也可以大于无调度指令资源的频域宽度,在这种情况下,频域上较宽的导频支持更多用户正交,频域上较窄的数据资源或资源池避免资源浪费。
作为示例,所述网络设备还可以配置导频的时域宽度(如图11所示),在导频占用的频域宽度较小的情况下,通过时域上扩展导频资源(CDM,TDM)可以增加正交用户数。作为示例,当导频占用多个符号时,导频占用连续的多个符号。
作为示例,可以为边缘用户(例如,图10中的终端设备3和终端设备4)和中心用户(例如,图9中的终端设备1和终端设备2)配置不同的导频资源和/或资源池。例如,可以为边缘用户配置频域上较窄的导频资源和无调度指令资源池。
作为示例,网络设备可以半静态配置传输资源大小以及约定的频域起始位置;所述网络设备也可以半静态配置传输资源大小,每种传输资源的频域起始位置按照预定义的规则约定,例如,可以按照跳频规则确定传输资源的起始位置,在这种情况下,跳频参数至少包含Tbsize/Tbtype,可以按照Freq_position=f(t,Tbtype)确定传输资源的频域起始位置;所述网络设备还可以使传输资源起始位置与导频资源对应,例如,网络设备可以为终端设备配置导频资源1和2,导频资源1指示传输资源起始位置1、3和5,导频资源2指示传输资源起始位置2和4。
作为示例,导频资源包括导频序列、导频图样和时/频域资源。导频资源可以配置一个符号或2个符号。
作为示例,终端设备可以按照预定义规则映射数据传输资源,也可以随机选择数据传输资源。
本领域普通技术人员可以理解实现上述实施例的全部或部分步骤可以通过硬件来完成,也可以通过程序来指令相关的硬件完成,所述的程序可以存储于一种计算机可读存储介质中,上述提到的存储介质可以是只读存储器,磁盘或光盘等。
以上所述仅为本申请的示例,并不用以限制本申请,凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。
