Description

电子设备、无线通信方法和计算机可读存储介质
本申请要求于2020年4月17日提交中国专利局、申请号为202010304595.5、发明名称为“电子设备、无线通信方法和计算机可读存储介质”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
本公开的实施例总体上涉及无线通信领域，具体地涉及电子设备、无线通信方法和计算机可读存储介质。更具体地，本公开涉及一种作为无线通信系统中的用户设备的电子设备、一种作为无线通信系统中的资源管理设备的电子设备、一种由无线通信系统中的用户设备执行的无线通信方法、一种由无线通信系统中的资源管理设备执行的无线通信方法以及一种计算机可读存储介质。
背景技术
在LTE系统中，基站对UE(User Equipment，用户设备)进行调度的方式主要有动态调度和半持续调度(Semi-Persistent Scheduling，SPS)。在动态调度方案中，当UE需要发送数据且没有上行资源时，会发送调度请求(Scheduling Request，SR)，以通知基站其有上行数据需要发送，基站接收到SR后会调度相关资源，供UE反馈缓存状态报告(Buffer Status Report，BSR)，然后基站根据UE发送的BSR调度相应的上行资源给UE发送数据。针对周期性的小包业务，基站可以通过观察统计得到UE的业务的大小和周期，然后可以调度多个上行资源给UE用于发送上行数据，不同上行资源之间的时间间隔可以通过RRC(Radio Resource Control，无线资源控制)信令来指示。这种调度方式被称为半持续调度。由于RRC信令中指示时间间隔的元素的大小有限，因此可以携带的时间间隔数量有限。
随着NR(New Radio，新无线)通信系统对越来越多的业务提供通信支持，这些业务传输需求的多样性也对目前的NR通信系统提出了一定的挑战。例如，超可靠低时延通信(Ultra-reliable and Low Latency Communications，uRLLC)业务对数据传输的时延和可靠性提出了很高的 需求。UE需要以uRLLC的方式周期性传输一些控制信息，这类传输通常是上行传输，且每次传输数据量较小。由于现有的标准支持的时间间隔有限，因此将造成配置上行资源的周期与业务的实际周期不匹配，从而导致较大的传输时延，同时造成资源的浪费。此外，UE的一些信息的传输频率是整数而传输周期不是整数，而RRC中的时间间隔仅能够指示有限的若干个资源分配的周期，因此也会造成配置上行资源的周期与业务的实际频率不匹配，从而导致较大的传输时延，同时造成资源的浪费。
因此，有必要提出一种技术方案，以支持更多种类的周期，从而降低周期性数据的传输时延，并且更加有效地利用资源。
发明内容

<1.综述>
前文中提到，对于传输时间量小且对传输时延要求高的周期性上行传输，由于现有的标准支持的时间间隔有限，因此将造成配置上行资源的周期与业务的实际周期不匹配，从而导致较大的传输时延，同时造成资源的浪费。
例如，发送业务数据的频率为60Hz(即发送业务数据的周期为16.67ms)，现有的标准中支持10ms和20ms的资源分配周期。这里，假定资源管理设备将资源分配周期设置为10ms。那么，数据到达时间、被分配的资源所在的时域位置以及数据发送的时延如下表所示。
表1
Figure PCTCN2020129263-appb-000001
从上表可以看出，数据在16.67ms到达，但是由于被分配的资源在 10ms和20ms的位置处，因此在10ms的位置处没有数据发送，造成了资源的浪费，在第20ms的位置处发送在第16.67ms到达的数据，因此造成了3.33ms的时延。类似地，数据在33.34ms到达，但是由于被分配的资源在30ms和40ms的位置处，因此在第30ms的位置处没有数据发送，造成了资源的浪费，在第40ms的位置处发送在第33.34ms到达的数据，因此造成了6.66ms的时延。
由此可见，由于现有的标准中支持的周期有限，所以资源的分配周期与业务的实际周期不匹配，造成了资源的浪费，从而降低了资源利用率，同时增大了数据传输的时延。
本公开针对这样的场景提出了一种无线通信系统中的电子设备、由无线通信系统中的电子设备执行的无线通信方法以及计算机可读存储介质，以支持更多种类的周期，从而降低周期性数据的传输时延，并且更加有效地利用资源。
根据本公开的资源管理设备可以是网络侧设备，其对覆盖范围内的用户设备进行资源管理。此外，资源管理设备也可以是用户设备，其对其他用户设备进行资源管理。例如，资源管理设备可以是由多个用户设备组成的簇的簇头设备，对簇内的其他用户设备进行资源管理。
根据本公开的无线通信系统可以是NR通信系统。
根据本公开的网络侧设备可以是任何类型的TRP(Transmit and Receive Port，发送和接收端口)，也可以是基站设备，例如可以是eNB，也可以是gNB(第5代通信系统中的基站)。
根据本公开的用户设备可以是移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)或者车载终端(诸如汽车导航设备)。用户设备还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)。此外，用户设备可以为安装在上述终端中的每个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。
<2.用户设备的配置示例>
图1是示出根据本公开的实施例的电子设备100的配置的示例的框图。这里的电子设备100可以作为无线通信系统中的用户设备。
如图1所示，电子设备100可以包括确定单元130和通信单元140。
这里，电子设备100的各个单元都可以包括在处理电路中。需要说明的是，电子设备100既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，电子设备100可以通过通信单元140从资源管理设备接收资源分配信息，资源分配信息显性地或者隐性地指示资源管理设备为电子设备100分配资源的周期或者资源管理设备为电子设备100分配资源的频率。
这里，资源管理设备用于对电子设备100的资源进行管理，包括向电子设备100分配用于发送数据的资源。资源管理设备例如可以是网络侧设备或者其他用户设备。
根据本公开的实施例，确定单元130可以根据资源分配信息确定资源管理设备为电子设备100分配资源的周期。
由此可见，根据本公开的实施例，资源分配信息可以显性地或者隐性地指示资源管理设备为电子设备100分配资源的周期或者频率。也就是说，资源分配可以支持周期和频率，因此电子设备100分配资源的周期与业务的实际周期或频率可以互相匹配，从而可以减小周期性业务的传输时延，提高资源的利用率。
下面将详细描述资源分配信息隐性地指示资源管理设备为电子设备100分配资源的周期或者频率的情形。
如图1所示，电子设备100可以包括业务流量信息生成单元110和解码单元120。
根据本公开的实施例，业务流量信息生成单元110用于生成电子设备100的业务流量信息，业务流量信息包括电子设备100发送的业务数据的周期性信息。
根据本公开的实施例，电子设备100可以通过通信单元140将业务流量生成单元110生成的业务流量信息发送至资源管理设备。
根据本公开的实施例，解码单元120可以对资源分配信息的一部分进行解扰，从而在解扰成功的情况下获取资源分配信息。
根据本公开的实施例，在解码单元120利用特定的RNTI(Radio  Network Tempory Identity，无线网络临时标识)对资源分配信息的一部分解扰成功的情况下，确定单元130可以根据业务流量信息生成单元110生成的业务流量信息中包括的周期性信息确定资源管理设备为电子设备100分配资源的周期或者频率。
由此可见，根据本公开的实施例的电子设备100，可以向资源管理设备发送业务数据的周期性信息，并在利用特定的RNTI对资源分配信息进行解扰成功的情况下，可以确定资源管理设备为电子设备100分配资源的周期或者频率是根据周期性信息确定的。也就是说，资源管理设备为电子设备100分配资源的周期或频率为周期性信息中包括的周期或频率。也就是说，电子设备100无需从资源管理设备接收资源管理设备为电子设备100分配资源的周期或频率，即资源管理设备用隐性的方式指示为电子设备100分配资源的周期或频率。这样一来，由于电子设备100上报的周期性信息可以支持较多种类的周期或频率，因此电子设备100分配资源的周期与业务的实际周期或频率互相匹配，从而可以减小周期性业务的传输时延，提高资源的利用率。
根据本公开的实施例，在逻辑信道中没有待发送的业务数据的情况下，业务流量信息生成单元110就可以生成业务流量信息，并且可以通过通信单元140向资源管理设备发送业务流量信息。
根据本公开的实施例，如图1所示，电子设备100还可以包括调度请求信息生成单元150，用于生成调度请求信息。
根据本公开的实施例，在逻辑信道中没有待发送的业务数据的情况下，调度请求信息生成单元150可以生成调度请求信息，并且电子设备100可以通过通信单元140向资源管理设备发送生成的调度请求信息。这里，调度请求信息可以用于请求用于发送业务流量信息的资源。
根据本公开的实施例，电子设备100可以通过通信单元140从资源管理设备接收资源管理设备响应于调度请求信息分配的用于发送业务流量信息的资源。接下来，电子设备100可以利用用于发送业务流量信息的资源向资源管理设备发送业务流量信息。
在现有的技术中，在逻辑信道中有待发送的业务数据的情况下才会向资源管理设备发送调度请求信息。并且资源管理设备只能根据观察统计得到电子设备发送业务数据的周期性信息。如果资源管理设备没有收到电子设备发送的请求，电子设备需要重复发送调度请求直到资源管理设备分 配相应的资源，从而导致时延很长。
根据本公开的实施例，可以在逻辑信道中没有待发送的业务数据的情况下就向资源管理设备发送调度请求信息和业务流量信息。此外，电子设备100可以主动地上报其发送的业务数据的周期性信息。这样一来，在逻辑信道中有待发送的业务数据之前，资源管理设备就可以根据电子设备100发送的业务数据的周期性信息为电子设备100分配资源，从而降低时延。
根据本公开的实施例，电子设备100可以利用MAC(Media Access Control，媒体接入控制)CE(Control Element，控制元素)承载业务流量信息。例如，电子设备100可以在MAC CE中的BSR(Buffer Status Report，缓存状态报告)中携带业务流量信息。
根据本公开的实施例，周期性信息可以表示电子设备100发送的业务数据的周期，例如可以包括电子设备100发送的业务数据的周期或者电子设备100发送的业务数据的频率。这里，周期可以是频率的倒数，因此根据发送业务数据的频率可以推算出发送业务数据的周期。
根据本公开的实施例，针对任意一个业务，电子设备100可以从周期和频率中选取是整数的那个参数，并将该参数作为周期性信息。例如，假定一个业务的周期是33.333ms，频率是3Hz，则电子设备100将频率3Hz作为周期性信息包括在业务流量信息中。
根据本公开的实施例，在利用周期性信息携带周期或频率的情况下，可以支持较多的周期或频率的数目。例如，电子设备100可以支持将1-1023ms范围内的任何整数周期、或者1-1023Hz范围内的任何整数频率作为周期性信息。
根据本公开的实施例，业务流量信息还可以包括表示周期性信息是周期还是频率的指示信息。例如，可以用1比特来表示该指示信息，当指示信息为1时表示周期性信息是周期，而指示信息为0时表示周期性信息是频率。
根据本公开的实施例，业务流量信息还可以包括缓存的业务数据的大小信息。这里，由于电子设备100可以在逻辑信道中没有待发送的业务数据的情况下就发送业务流量信息，因此缓存的业务数据的大小可以为0。
根据本公开的实施例，如图1所示，电子设备100还可以包括估计单元160，用于估计业务数据的到达时间。例如，电子设备100可以根据 即将发送的业务数据的大小和周期来估计业务数据即将到达的时间。进一步，业务流量信息还可以包括估计单元160预计的业务数据的到达时间信息。
如上所述，业务流量信息可以包括电子设备100发送的业务数据的周期性信息。可选地，业务流量信息还包括以下中的至少一种：表示周期性信息是周期还是频率的指示信息、缓存的业务数据的大小信息、以及预计的业务数据的到达时间信息。
图2是示出根据本公开的实施例的业务流量信息的内容的示意图。如图2所示，1比特的指示信息表示业务流量信息中包括的是周期还是频率，7比特的频率/周期的第1部分表示频率或者周期的第1部分内容，8比特的频率/周期的第2部分表示频率或者周期的第2部分内容，即最多可以用15比特来表示频率或者周期，4比特的到达时间信息表示估计单元160估计的业务数据的到达时间信息，4比特的大小信息表示缓存的业务数据的大小。
根据本公开的实施例，电子设备100可以通过DCI(Downlink Control Information，下行控制信息)和RRC从资源管理设备接收资源分配信息。
在现有的方案中，在SPS调度方式中，资源管理设备发送的DCI中至少包括为电子设备100分配的在各个周期发送业务数据的频域资源以及为电子设备100分配的首次发送业务数据的时域资源。此外，资源管理设备还可以向电子设备100发送包括为电子设备100分配资源的周期性信息的RRC信令。也就是说，资源管理设备利用显性的方式指示分配资源的周期。此外，资源管理设备可以利用与SPS调度方式相对应的RNTI对DCI进行加扰，电子设备100可以利用相应的RNTI对该DCI进行解扰从而确定调度方式为SPS并且获取DCI中的内容。这样一来，电子设备100可以通过DCI中包括的在各个周期发送业务数据的频域资源和首次发送业务数据的时域资源、以及RRC信令中包括的周期性信息确定在各个周期发送业务数据的资源。
根据本公开的实施例，资源管理设备发送的RRC信令中可以不包括为电子设备100分配资源的周期性信息。也就是说，资源管理设备利用隐性的方式指示分配资源的周期。此外，资源管理设备可以利用特定的RNTI对DCI进行加扰。这种特定的RNTI是新设置的RNTI，不同于现有的方案中的与SPS调度方式相对应的RNTI。也就是说，这种特定的RNTI对应于SPS调度方式中在RRC信令不包括周期性信息的情况下的资源分配 信息。
根据本公开的实施例，对于SPS调度方式，电子设备100可能收到包括资源管理设备为电子设备100分配资源的周期性信息的RRC信令，也可能收到不包括资源管理设备为电子设备100分配资源的周期性信息的RRC信令。因此，在电子设备100收到资源分配信息之后，可以利用与SPS调度方式中在RRC信令包括周期性信息的情况下的资源分配信息相对应的RNTI(表2中的第二种RNTI)对该资源分配信息进行解扰，也可以利用与SPS调度方式中在RRC信令不包括周期性信息的情况下的资源分配信息相对应的RNTI(表2中的第三种RNTI)对该资源分配信息进行解扰。在电子设备100利用与在RRC信令中包括周期性信息的情况下的资源分配信息相对应的RNTI对该资源分配信息进行解扰成功的情况下，电子设备100可以根据RRC信令中包括的周期性信息确定资源管理设备为其分配资源的周期；在电子设备100利用与在RRC信令中不包括周期性信息的情况下的资源分配信息相对应的RNTI对该资源分配信息进行解扰成功的情况下，电子设备100可以根据业务流量信息中包括的周期性信息确定资源管理设备为其分配资源的周期。
根据本公开的实施例，对资源分配信息进行加扰的RNTI可能有以下三种：
表2
Figure PCTCN2020129263-appb-000002
在表2中，第一种RNTI和第二种RNTI为现有的方案中的RNTI，而第三种RNTI是本公开新增的RNTI，用于对SPS调度方式下在RRC信令不包括周期性信息的情况下的资源分配信息进行加扰和解扰。
如上所述，在RRC信令包括周期性信息的情况下，由于RRC信令中指示周期性信息的资源有限并且仅能够指示资源分配的周期，因此支持的周期的数目有限。在RRC信令不包括周期性信息的情况下，由于可以 隐性地指示资源分配的周期，因此可以支持很大数目的周期。也就是说，在RRC信令中不包括周期性信息的情况下支持的周期的数目不同于在RRC信令中包括周期性信息的情况下支持的周期的数目。更具体地，在RRC信令中不包括周期性信息的情况下支持的周期的数目大于在RRC信令中包括周期性信息的情况下支持的周期的数目。
下面将详细描述资源分配信息显性地指示资源管理设备为电子设备100分配资源的周期或者资源管理设备为电子设备分配资源的频率的情形。
根据本公开的实施例，资源分配信息可以包括资源管理设备为电子设备100分配资源的周期或者资源管理设备为电子设备100分配资源的频率。
在这个实施例中，电子设备100可以通过RRC信令来接收这样的资源分配信息。也就是说，电子设备100接收到的资源分配信息可以包括通过RRC承载的资源分配信息和通过DCI承载的资源分配信息。其中，DCI中至少包括为电子设备100分配的在各个周期发送业务数据的频域资源以及为电子设备100分配的首次发送业务数据的时域资源，而RRC中至少包括资源管理设备为电子设备100分配资源的周期或者资源管理设备为电子设备100分配资源的频率。
根据本公开的实施例，如图1所示，电子设备100还可以包括存储单元180，用于存储资源分配列表，资源分配列表包括资源管理设备支持的为电子设备100分配资源的周期和/或为电子设备100分配资源的频率的列表。
根据本公开的实施例，确定单元130可以根据资源分配列表和资源分配信息确定资源管理设备为电子设备100分配资源的周期或者频率。
根据本公开的实施例，资源分配信息可以包括资源管理设备为电子设备100分配资源的周期或者频率的标识，并且资源分配列表中可以包括资源管理设备支持的为电子设备100分配资源的各个周期和/或为电子设备100分配资源的各个频率与标识的映射关系。这样一来，确定单元130可以根据资源分配信息中包括的标识查找资源分配列表从而确定资源管理设备为电子设备100分配资源的周期或者频率。
例如，资源分配列表中包括10ms、20ms、30Hz和60Hz，标识分别为00、01、10和11，则在资源分配信息中包括标识11的情况下，确定单 元130可以确定资源管理设备为电子设备100分配资源的频率是60Hz。这里以资源分配列表支持周期和频率为例进行了说明，资源分配列表还可以仅仅包括频率。
根据本公开的实施例，资源分配信息也可以包括：表示资源分配信息包括资源管理设备为电子设备100分配资源的周期还是资源管理设备为电子设备100分配资源的频率的指示信息。例如，资源分配信息中可以包括1比特的指示信息，当指示信息为0时表示资源分配信息中包括的是周期，而当指示信息为1时表示资源分配信息中包括的是频率。在这个实施例中，资源分配信息可以包括指示信息、以及周期或者频率的标识。资源分配列表中可以包括资源管理设备支持的为电子设备100分配资源的各个周期和/或为电子设备100分配资源的各个频率与标识的映射关系。这样一来，确定单元130可以根据指示信息确定资源管理设备以周期还是频率的方式分配资源资源，再根据资源分配信息中包括的标识查找资源分配列表从而确定资源管理设备为电子设备100分配资源的周期或者频率。
例如，资源分配列表中包括10ms、20ms、30Hz和60Hz，标识分别为0、1、0和1，则在资源分配信息中包括指示信息0并且资源分配信息中包括标识1的情况下，确定单元130可以确定资源管理设备为电子设备100分配资源的周期是20ms。
此外，根据本公开的实施例，在资源分配列表仅仅支持频率或者仅仅支持周期的情况下，资源分配信息也可以不包括上述指示信息。
根据本公开的实施例，电子设备100可以通过通信单元140从资源管理设备接收这样的资源分配列表。例如，电子设备100可以通过RRC信令从资源管理设备接收这样的资源分配列表。此外，电子设备100和资源管理设备也可以预配置这样的资源分配列表。
如上所述，根据本公开的实施例，在资源分配信息显性地指示资源管理设备为电子设备100分配资源的周期或者频率的情况下，由于资源分配信息支持频率的方式，因此可以支持一些发送频率是整数而发送周期不是整数的情形，从而使得资源分配的频率与电子设备100发送业务数据的频率相匹配，减少数据传输时延，提高资源利用率。
如上详细描述了资源分配信息显性地或者隐性地指示资源管理设备为电子设备100分配资源的周期或者频率的实施例。根据本公开的实施例，在资源分配信息显性地或者隐性地指示资源管理设备为电子设备100 分配资源的频率的情况下，确定单元130还需要根据资源管理设备为电子设备100分配资源的频率确定资源管理设备为电子设备100分配资源的周期。进一步，确定单元130还可以根据资源分配信息以及资源管理设备为电子设备100分配资源的周期来确定电子设备100在各个周期发送业务数据的资源。
根据本公开的实施例，资源分配信息可以包括电子设备100在各个周期发送业务数据的频域资源以及电子设备100首次发送业务数据的时域资源，因此确定单元130可以根据资源分配信息确定在各个周期发送业务数据的频域资源以及首次发送业务数据的时域资源。
根据本公开的实施例，确定单元130可以根据首次发送业务数据的时域资源以及资源管理设备为电子设备100分配资源的周期来确定在各个周期发送业务数据的时域资源。由此，确定单元130可以确定电子设备100在各个周期发送业务数据的时域资源和频域资源。
根据本公开的实施例，在资源分配信息显性地或者隐性地指示资源管理设备为电子设备100分配资源的周期的情况下，确定单元130可以根据以下公式来确定在各个周期发送业务数据的时域资源：
tn＝t1+T×(n-1)
其中，tn表示在第n(n为正整数)个周期发送业务数据的时域资源，单位为ms，t1表示首次发送业务数据的时域资源，单位为ms，可以从资源分配信息得到。T表示资源管理设备为电子设备100分配资源的周期，单位为ms。
在资源分配信息显性地或者隐性地指示资源管理设备为电子设备100分配资源的频率的情况下，由该频率计算出的周期可能不是资源管理设备分配时域资源的最小单位的整数倍。例如，资源管理设备为电子设备100分配资源的频率为60GHz，则根据该频率计算出的资源管理设备为电子设备100分配资源的的周期为16.666ms，而资源管理设备分配时域资源的最小单位为1ms，因此16.666ms不是1ms的整数倍。
根据本公开的实施例，在分配资源的周期不是资源管理设备分配时域资源的最小单位的整数倍的情况下，确定单元130可以将在各个周期发送业务数据的时域资源调整为最小单位的整数倍。
根据本公开的实施例，确定单元130可以根据首次发送业务数据的时域资源以及分配资源的周期来确定在各个周期发送业务数据的时间，并 且通过将该时间向上取整来将该时间调整为最小单位的整数倍。
例如，确定单元130可以根据下述公式来确定在各个周期发送业务数据的时域资源：
tn＝t1+cell(1000/f×(n-1))
其中，tn表示在第n(n为正整数)个周期发送业务数据的时域资源，单位为ms，t1表示首次发送业务数据的时域资源，单位为ms，可以从资源分配信息得到。f表示资源管理设备为电子设备100分配资源的频率，单位为GHz。1000/f表示资源管理设备为电子设备100分配资源的周期，单位为ms。cell表示向上取整操作。这里，由于t1是整数，因此上述公式也可以写为：
tn＝cell(t1+1000/f×(n-1))
其中，t1+1000/f×(n-1)表示确定单元130根据首次发送业务数据的时域资源以及分配资源的周期确定的在各个周期发送业务数据的时间，确定单元130通过将该时间向上取整来将该时间调整为最小单位的整数倍。
例如，假定f＝60GHz，t1＝1ms，则t2＝18ms，t3＝35ms，t4＝51ms，以此类推。
如上所述，根据本公开的实施例，确定单元130可以先根据首次发送业务数据的时域资源以及分配资源的周期确定在各个周期发送业务数据的时间，然后再将该时间调整为最小单位的整数倍。这样一来，资源管理设备为电子设备100分配的资源就不是严格的周期性资源，可能略有偏差。例如，在上面的示例中，t1与t2的间隔为17ms，t2与t3的间隔为17ms，而t3与t4的间隔为16ms。
根据本公开的实施例，确定单元130也可以通过将分配资源的周期向上取整来将周期调整为最小单位的整数倍，然后根据首次发送业务数据的时域资源以及调整后的周期来确定在各个周期发送业务数据的时域资源。
例如，确定单元130可以根据下述公式来确定在各个周期发送业务数据的时域资源：
tn＝t1+(n-1)×cell(1000/f)
类似地，tn表示在第n(n为正整数)个周期发送业务数据的时域资源，单位为ms，t1表示首次发送业务数据的时域资源，单位为ms，可以 从资源分配信息得到。f表示资源管理设备为电子设备100分配资源的频率，单位为GHz。1000/f表示资源管理设备为电子设备100分配资源的周期，单位为ms。cell表示向上取整操作。
在上述公式中，cell(1000/f)表示确定单元130通过将分配资源的周期向上取整获得的为最小单位的整数倍的周期，然后确定单元130再根据首次发送业务数据的时域资源以及调整后的周期来确定在各个周期发送业务数据的时域资源。
例如，假定f＝60GHz，t1＝1ms，则调整后的周期为17ms，因此t2＝18ms，t3＝35ms，t4＝52ms，以此类推。
如上所述，由于确定单元130先将分配资源的周期调整为最小单位的整数倍，再计算在各个周期发送业务数据的时域资源，因此资源管理设备为电子设备100分配的资源是严格的周期性资源。
如上所述，根据本公开的实施例，在分配资源的周期不是资源管理设备分配时域资源的最小单位的整数倍的情况下，电子设备100可以与资源管理设备约定好将在各个周期发送业务数据的时域资源调整为分配时域资源的最小单位的整数倍的方式，从而使得电子设备100确定的为电子设备100分配的资源和资源管理设备确定的为电子设备100分配的资源保持一致。这样一来，电子设备100也能够以与资源管理设备一致的方式确定出为其分配的资源。
根据本公开的实施例，如图1所示，电子设备100还可以包括数据生成单元170，用于生成要发送的业务数据。进一步，在逻辑信道中有待发送的业务数据的情况下，电子设备100可以根据确定单元130确定的电子设备100在各个周期发送业务数据的资源、通过通信单元140来发送业务数据。
图3是示出根据本公开的实施例的由用户设备请求上行资源并发送数据的信令流程图。在图3中，UE可以由电子设备100来实现。如图3所示，在步骤S301中，在业务数据尚未到达逻辑信道的情况下，UE向资源管理设备发送调度请求信息。接下来，在步骤S302中，资源管理设备可以向UE分配用于发送业务流量信息的上行资源。接下来，在步骤S303中，UE利用资源管理设备分配的上行资源发送业务流量信息。接下来，在步骤S304中，资源管理设备例如通过资源分配信息向UE分配用于发送上行数据的资源，从而UE可以通过本公开的实施例确定在各个周期发 送业务数据的资源。接下来，在步骤S305中，在业务数据到达逻辑信道的情况下，UE根据确定的各个周期发送业务数据的资源向资源管理设备发送上行数据。这里，虽然图3示出了UE向资源管理设备发送上行数据的情形，实际上UE也可以向其他设备发送上行数据。
根据本公开的实施例，在电子设备100向资源管理设备发送业务流量信息之前，电子设备100还可以向资源管理设备发送BSR(在下文中被称为第一BSR)，以向资源管理设备通知电子设备100期望对尚未到达逻辑信道的数据预先申请资源。
图4是示出根据本公开的实施例的第一缓存状态报告的内容的示意图。图4示出了短BSR(即仅有一个逻辑信道)的情形。在图4中，逻辑信道ID表示该BSR针对的逻辑信道的标识，缓存大小表示缓存的业务数据的大小。由于业务数据尚未到达逻辑信道，因此这里可以为0。
图5是示出根据本公开的实施例的第一缓存状态报告的内容的示意图。图5示出了长BSR(即有多个逻辑信道)的情形。在图5中，LCG 0-LCG 7分别表示8个逻辑信道中的相应逻辑信道中是否有数据传输。例如，LCG 0＝1表示编号为0的逻辑信道中有数据传输，LCG 1＝0表示编号为1的逻辑信道中没有数据传输，依次类推。缓存大小1、缓存大小2、…缓存大小m表示有数据传输的各个逻辑信道中的缓存数据的大小，m表示LCG 0-LCG 7中为1的数目。例如，假定LCG 0、LCG 1、LCG 2、LCG 5为1，LCG 3、LCG 4、LCG 6、LCG 7为0，则m＝4，缓存大小1表示编号为0的逻辑信道中的缓存数据的大小，缓存大小2表示编号为1的逻辑信道中的缓存数据的大小，缓存大小3表示编号为2的逻辑信道中的缓存数据的大小，缓存大小4表示编号为5的逻辑信道中的缓存数据的大小。由于业务数据尚未到达逻辑信道，因此可以将所有的缓存大小设置为0，LCG 0-LCG 7也设置为0，或者可以将所有的缓存大小设置为0，LCG 0-LCG 7设置为1。
根据本公开的实施例，资源管理设备在收到图4或者图5所示的第一BSR的情况下，并不认为出现了异常，而是可以确定电子设备100期望为即将到来的业务数据预先申请资源。在这种情况下，资源管理设备可以继续为电子设备100分配用于发送第二BSR的上行资源。这里的第二BSR例如可以包括前文中所述的业务流量信息，即如图2所示的示例。
图6是示出根据本公开的实施例的由用户设备请求上行资源并发送数据的信令流程图。在图6中，UE可以由电子设备100来实现。如图6所示，在步骤S601中，在业务数据尚未到达逻辑信道的情况下，UE向资 源管理设备发送调度请求信息。接下来，在步骤S602中，资源管理设备向UE分配用于发送第一缓存状态报告的资源。接下来，在步骤S603中，UE利用资源管理设备分配的资源向资源管理设备发送第一缓存状态报告(例如图4或者图5所示的示例)。接下来，在步骤S604中，资源管理设备向UE分配用于发送第二缓存状态报告的资源。接下来，在步骤S605中，UE向资源管理设备发送第二缓存状态报告(例如图2所示的示例)。接下来，在步骤S606中，资源管理设备向UE分配用于发送上行数据的资源。接下来，在业务数据到达逻辑信道的情况下，UE利用资源管理设备分配的资源发送上行数据。这里，虽然图6示出了UE向资源管理设备发送上行数据的情形，实际上UE也可以向其他设备发送上行数据。
如上所述，根据本公开的实施例，UE可以先向资源管理设备发送第一缓存状态报告，再向资源管理设备发送包括业务流量信息的第二缓存状态报告。这里，第一缓存状态报告与现有标准中的缓存状态报告兼容，因此可以在对现有标准改动较小的情况下实现周期性信息的上报。
以上描述了在无线通信网络中具有资源管理设备的情况下电子设备100预先申请用于发送业务数据的资源的实施例。下面将描述在无线通信网络中没有资源管理设备的情况下电子设备100预先申请用于发送业务数据的资源的实施例。
考虑以下的场景：在V2X(车辆与其他设备)mode 2(模式2)的通信场景中，不存在资源分配设备，作为用户设备的车辆之间自行协调资源。例如，在作为用户设备的车辆需要发送业务数据的情况下，可以在数据到达之后，在特定的时频资源上广播对后续资源的占用，然后在预定时间范围内利用提前占用的资源发送业务数据。这种占用可以包括单次的占用，也可以包括周期性的占用。
在现有的方案中，由于作为用户设备的车辆只能够在预定时间范围内选择要占用的资源并且发送业务数据，其中预定时间范围是根据对时延的约束确定的，因此在时延要求比较高，即预定时间范围比较小的情况下，车辆就有可能无法选取合适的资源。
图7是示出用户设备无法选择合适的资源发送数据的情况的示意图。如图7所示，在时刻t1，UE1需要发送的业务数据到达逻辑信道，k表示预定时间范围，即UE1必须在时刻t1+k之前将业务数据发送出去。在k比较小，例如1ms的情况下，UE1可能来不及选取合适的资源。如图7所示，UE1选取的时频资源超出了时刻t1+k，因此无法满足时延的要求。
根据本公开的实施例，电子设备100可以在业务数据到达逻辑信道之前，发送对发送该业务数据所使用的资源的占用信息，该占用信息可以包括资源的时域和频域位置。优选地，电子设备100可以广播发送这样的占用信息。可选地，如果电子设备100想周期性占用资源，占用信息还可以包括资源占用的周期性信息，例如可以包括资源占用的周期或者资源占用的频率。进一步，在业务数据到达逻辑信道之后并且在预定时间范围内，电子设备100可以利用占用信息中包括的资源发送业务数据。
图8是示出根据本公开的实施例的用户设备提前广播要占用的资源的示意图。在图8中，UE1可以由电子设备100来实现。如图8所示，时刻t1为业务数据到达逻辑信道的时刻。在业务数据到达逻辑信道之前，UE1发送占用信令，该信令可以包括UE1选择的时频资源的位置。然后在t1+k时刻以内(包括t1+k时刻)，UE1利用选择的时频资源发送业务数据。
如上所述，根据本公开的实施例，由于电子设备100在业务数据到达逻辑信道之前可以广播资源的占用信息，因此可以提前占用资源，从而确保在预定时间范围内发送业务数据，满足时延的要求。
由此可见，根据本公开的实施例，在无线通信网络中包括资源管理设备的情况下，需要发送数据的电子设备可以在逻辑信道中没有待发送的业务数据的情况下就向资源管理设备发送其发送的业务数据的周期性信息。这样一来，在逻辑信道中有待发送的业务数据之前，资源管理设备就可以根据电子设备发送的业务数据的周期性信息为电子设备分配资源，从而降低时延。此外，根据本公开的实施例，在无线通信网络中不包括资源管理设备的情况下，需要发送数据的电子设备可以在业务数据到达逻辑信道之前广播资源的占用信息，从而确保在预定时间范围内发送业务数据，满足时延的要求。
<3.资源管理设备的配置示例>
图9是示出根据本公开的实施例的无线通信系统中的用作资源管理设备的电子设备900的结构的框图。这里，电子设备900是能够执行资源管理功能的电子设备。例如，电子设备900可以是网络侧设备，管理其覆盖范围内的用户设备的资源。再如，电子设备900也可以是用户设备，管理其他用户设备的资源。在这种情况下，电子设备900可以是由多个用户设备构成的簇的簇头设备，管理该簇内的其他用户设备的资源。
如图9所示，电子设备900可以包括通信单元930和生成单元940。
这里，电子设备900的各个单元都可以包括在处理电路中。需要说明的是，电子设备900既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，生成单元940可以生成资源分配信息，资源分配信息显性地或者隐性地指示电子设备900为用户设备分配资源的周期或者电子设备900为用户设备分配资源的频率。例如，电子设备900可以通过DCI和RRC来承载资源分配信息。
根据本公开的实施例，电子设备900可以通过通信单元930向用户设备发送资源分配信息。
下面将详细描述资源分配信息隐性地指示电子设备900为用户设备分配资源的周期或者电子设备900为用户设备分配资源的频率的情形。
根据本公开的实施例，电子设备900还可以包括确定单元910、分配单元920和编码单元950。
根据本公开的实施例，电子设备900可以通过通信单元930从用户设备接收用户设备的业务流量信息，业务流量信息包括用户设备发送的业务数据的周期性信息。
根据本公开的实施例，确定单元910可以根据周期性信息确定为用户设备分配资源的周期或者频率。具体地，确定单元910可以将周期性信息中包括的周期或者频率确定为为用户设备分配资源的周期或者频率。
根据本公开的实施例，分配单元920可以根据确定单元910确定的周期为用户设备分配资源。
根据本公开的实施例，编码单元950可以对生成单元940生成的资源分配信息进行编码，例如加扰。
这里，在SPS调度方式中，在RRC信令不包括周期性信息的情况下，编码单元950可以利用与SPS调度方式下在RRC信令不包括周期性信息的情况下的资源分配信息相对应的RNTI(即特定的RNTI)对该资源分配信息进行加扰，以指示为用户设备分配资源的周期或者频率是根据周期性信息确定的。
而在SPS调度方式中，在RRC信令包括周期性信息的情况下，编码单元950可以利用与在SPS调度方式下RRC信令包括周期性信息的情况下的资源分配信息相对应的RNTI对该资源分配信息进行加扰。
由此可见，根据本公开的实施例的电子设备900，可以根据用户设备上报的发送业务数据的周期或频率来确定为用户设备分配资源的周期或频率。进一步，电子设备900可以用隐性的方式指示为用户设备分配资源的周期或频率。这样一来，由于用户设备上报的周期性信息可以支持较多种类的周期，因此分配资源的周期与用户设备的业务的实际周期或频率互相匹配，从而可以减小周期性业务的传输时延，提高资源的利用率。
这里，在电子设备900收到了来自用户设备的业务流量信息并根据业务流量信息中包括的周期性信息确定为用户设备分配资源的周期的情况下，生成单元940生成的资源分配信息(DCI)可以包括为用户设备分配的在各个周期发送业务数据的频域资源和为用户设备分配的首次发送业务数据的时域资源，而电子设备900无需向用户设备发送为用户设备分配资源的周期性信息。
此外，在电子设备900没有收到来自用户设备的业务流量信息并且通过观察统计确定出为用户设备分配资源的周期的情况下，生成单元940生成的资源分配信息(DCI)可以包括为用户设备分配的在各个周期发送业务数据的频域资源和为用户设备分配的首次发送业务数据的时域资源，并且资源分配信息(RRC)还包括为用户设备分配资源的周期性信息。
根据本公开的实施例，如图9所示，根据本公开的实施例，电子设备900还可以通过通信单元930从用户设备接收调度请求信息。进一步，分配单元920可以响应于调度请求信息，为用户设备分配用于发送业务流量信息的资源。
根据本公开的实施例，业务流量信息可以通过MAC CE来承载。具体地，业务流量信息可以被包括在MAC CE中的BSR中。
根据本公开的实施例，周期性信息可以包括用户设备发送的业务数据的周期或者用户设备发送的业务数据的频率。确定单元910可以根据业务流量信息中包括的周期性信息确定用户设备发送的业务数据的周期或者用户设备发送的业务数据的频率。进一步，在周期性信息包括用户设备发送的业务数据的频率的情况下，确定单元910可以根据频率确定周期，例如根据频率的倒数确定周期。
根据本公开的实施例，业务流量信息还可以包括以下中的至少一种：表示周期性信息是周期还是频率的指示信息、用户设备缓存的业务数据的大小信息、以及用户设备预计的业务数据的到达时间信息。确定单元910可以根据指示信息以及周期性信息来确定用户设备发送的业务数据的周期，分配单元920可以根据用户设备预计的业务数据的到达时间信息来为用户设备分配资源。
根据本公开的实施例，在电子设备900接收到如图4或图5所示的第一BSR的情况下，电子设备900还可以为用户设备分配用于发送第二BSR的上行资源，并通过第二BSR来获取业务流量信息。
下面将详细描述资源分配信息隐性地指示电子设备900为用户设备分配资源的周期或者电子设备900为用户设备分配资源的频率的情形。
根据本公开的实施例，生成单元940生成的资源分配信息包括电子设备900为用户设备分配资源的周期或者电子设备900为所述用户设备分配资源的频率。例如，资源分配信息可以包括电子设备900为用户设备分配资源的周期或者频率的标识。
根据本公开的实施例，电子设备900还可以包括生成单元960，用于生成资源分配列表，资源分配列表包括电子设备900支持的为用户设备分配资源的周期和/或频率的列表。具体地，资源分配列表可以包括电子设备900支持的为用户设备分配资源的各个周期和/或各个频率的列表与各个周期或者各个频率的标识之间的映射关系。进一步，电子设备900可以通过通信单元930向用户设备发送资源分配列表。例如，电子设备900可以通过RRC信令承载这样的资源分配列表。
根据本公开的实施例，电子设备900和用户设备也可以预配置这样的资源分配列表。
根据本公开的实施例，生成单元960生成的资源分配信息还可以包括：表示资源分配信息包括电子设备900为用户设备分配资源的周期还是电子设备900为所述用户设备分配资源的频率的指示信息。例如，资源分配信息中可以包括1比特的指示信息，当指示信息为0时表示资源分配信息中包括的是周期，而当指示信息为1时表示资源分配信息中包括的是频率。在这个实施例中，资源分配信息可以包括指示信息、以及周期或者频率的标识。资源分配列表中可以包括资源管理设备支持的为电子设备100分配资源的各个周期和/或为电子设备100分配资源的各个频率与标识的 映射关系。
如上所述，根据本公开的实施例，在资源分配信息显性地指示电子设备900为用户设备分配资源的周期或者频率的情况下，由于资源分配信息支持频率的方式，因此可以支持一些发送频率是整数而发送周期不是整数的情形，从而使得资源分配的频率与用户设备发送业务数据的频率相匹配，减少数据传输时延，提高资源利用率。
如上详细描述了资源分配信息显性地或者隐性地指示电子设备900为用户设备分配资源的周期或者频率的实施例。根据本公开的实施例，在资源分配信息显性地或者隐性地指示电子设备900为用户设备分配资源的频率的情况下，分配单元920需要根据电子设备900为用户设备分配资源的频率确定电子设备900为用户设备分配资源的周期。进一步，分配单元920可以根据用户设备首次发送业务数据的时域资源以及电子设备900为用户设备分配资源的周期来确定用户设备在各个周期发送业务数据的时域资源。
根据本公开的实施例，在分配资源的周期不是电子设备900分配时域资源的最小单位的整数倍的情况下，分配单元920可以将用户设备在各个周期发送业务数据的时域资源调整为最小单位的整数倍。
根据本公开的实施例，分配单元920可以根据用户设备首次发送业务数据的时域资源以及分配资源的周期来确定用户设备在各个周期发送业务数据的时间，并且通过将时间向上取整来将时间调整为最小单位的整数倍。
根据本公开的实施例，分配单元920也可以通过将分配资源的周期向上取整来将周期调整为最小单位的整数倍，并且根据用户设备首次发送业务数据的时域资源以及调整后的周期来确定用户设备在各个周期发送业务数据的时域资源。
这里，分配单元920根据用户设备首次发送业务数据的时域资源以及电子设备900为用户设备分配资源的周期来确定用户设备在各个周期发送业务数据的时域资源的方式可以与电子设备100中的确定单元130确定的方式类似，在此不再赘述。也就是说，电子设备900应当与用户设备约定好确定在各个周期发送业务数据的资源的方式，以与用户设备一致的方式来确定为用户设备分配的资源。
如上所述，根据本公开的实施例，电子设备900可以用显性或者隐 性的方式指示为用户设备分配资源的周期，从而支持较多种类的周期，使得分配资源的周期与用户设备的业务的实际周期互相匹配，从而可以减小周期性业务的传输时延，提高资源的利用率。

<关于基站的应用示例>
(第一应用示例)
