Description

接入控制方法、装置、用户设备及基站 技术领域
本公开涉及通信技术领域，尤其涉及一种接入控制方法、装置、用户设备及基站。
背景技术
随着无线通信技术的飞速发展，授权频谱上的频谱资源大多都被各种通信系统占用，因此为了扩大频率资源，无线通信系统将工作频段扩展到了非授权频段。
为了将第五代移动通信技术(5th Generation，简称为5G)新空口(New Radio，简称为NR)技术扩展到非授权频段上，第三代合作伙伴计划(3rd Generation Partnership Project，简称为3GPP)通过了基于NR的非授权频谱接入的研究，以便NR能够满足非授权频段的法规要求。基于研究结论，支持新空口的非授权频段接入(New Radio Access to Unlicensed spectrum，简称为NR-U)的用户设备在接入网络时需要遵循先听后说(Listen-Before-Talk，简称为LBT)的信道竞争接入机制。支持NR-U的UE可能会因为非授权频段资源竞争激烈而导致LBT一直失败，进而降低UE的随机接入成功率，影响NR-U系统的性能。因此为了提高NR-U系统的性能，需要提出一种新的随机接入方案，来提高支持NR-U的UE的随机接入成功率。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
本公开提供的技术方案适用于支持NR-U的通信系统，在基于新空口非授权频道接入的通信系统中，支持NR-U的UE在接入网络时，需要先信道检侧，并在LBT检测成功时执行随机接入操作。
图1A是根据一示例性实施例示出的一种接入控制方法的流程图，图1B是根据一示例性实施例示出的一种接入控制方法的场景图；该接入控制方法可以应用在用户设备上，如图1A所示，该接入控制方法包括以下步骤110-130：
在步骤110中，确定待检测信道进行LBT检测的结果，待检测信道为用于发送随机接入前导码的非授权信道。
在一实施例中，通常可通过检测信道的信号能量得到LBT检测的结果，例如，在待检测信道的信号能量值低于一个设定的门限值时，可确定待检测信道的LBT检测 的结果为失败；在信号能量值不低于一个设定的门限值时，可确定待检测信道的LBT检测的结果为成功。对信道进行LBT检测的实现方式可参见LBT检侧的相关技术方案，这里不再描述。
在步骤120中，若LBT检测的结果为失败，对前导码传输计数器进行加一操作并且确定前导码传输计数器的计数值。
本公开实施例中，在由于LBT检测的结果为失败而导致不能发送随机接入前导码时，会同时增加前导码传输计数器的计数值，而在前导码传输计数器的计数值达到前导码最大传输次数时，则通常意味着此次随机接入过程失败，因此在由于LBT检测的结果为失败而对前导码传输计数器进行加一操作后需要确定前导码传输计数器的计数值是否已达到前导码最大传输次数。
在步骤130中，若前导码传输计数器的计数值达到前导码最大传输次数，执行无线链路失败处理。
在一实施例中，如果前导码传输计数器的计数值达到前导码最大传输次数，则可触发RLF，并执行无线链路失败处理操作，例如，向网络侧上报RLF报告，或者尝试接入其他基站等。
在一实施例中，前导码最大传输次数与待传输业务的业务类型或者服务质量等级标识之间存在对应关系。
在一实施例中，前导码传输计数器PREAMBLE_TRANSMISSION_COUNTER所可计数的最大值为前导码最大传输次数，本公开实施例中前导码最大传输次数与业务类型或QCI存在对应关系。其中，业务类型可以指示为具体的业务，例如，业务类型为视频业务，或者待传输业务为普通的上网服务等。
在一实施例中，不同的业务类型，对带宽、速率、时延、可靠性等方面的要求不同，例如，业务类型为超高可靠与低时延通信(Ultra Reliable&Low Latency Communication，简称为URLLC)的业务，对网络的时延要求非常高，则为了提高URLLC业务的业务数据的传输效率，避免时延过长，可将URLLC业务对应的前导码最大传输次数设置为一个比较小的值，由此可实现支持NR-U的UE可以对信道进行LBT检测的次数会少一些，进而实现UE可在非授权信道比较繁忙的情况下尽早地选择其它方式接入网络，提高接入成功率和业务数据的传输效率。
在一实施例中，不同的业务需要不同等级的QCI传输质量进行保证，而不同的QCI质量对带宽、速率、时延、可靠性(数据丢包率)等方面的服务质量不相同，因此本公开技术方案中可以针对不同的QCI级别设置对应的前导码最大传输次数。
在一实施例中，业务类型或QCI与前导码最大传输次数之间的对应关系可以由通信协议预先规定好，由此用户设备可直接基于通信协议规定获取到该对应关系；在一实施例中，用户设备还可通过基站的广播的第一系统消息块(System Information Block1，简称为SIB1)获取到该对应关系。
在一示例性场景中，如图1B所示，以移动网络为5G网络并且基站为演进型基站(eNB)为例进行示例性说明，在图1B所示的场景中，包括eNB10、UE20，其中，eNB10和UE20均支持NR-U，UE20在准备进行随机接入时，需要对用于发送随机接入前导码的非授权信道进行LBT检测，并在每次LBT检测的结果为失败时对前导码传输计数器进行加一操作，前导码传输计数器达到前导码传输最大传输次数时，则可执行RLF处理，例如，可向网络侧上报RLF报告，或者接入其他的基站，由于前导码最大传输次数与UE20的待传输业务相关，因此可以确保支持NR-U的UE20根据不同的业务类型选择前导码最大传输次数，进而提高随机接入的成功率。
本实施例中，通过上述步骤110-步骤130，在支持NR-U的UE进行随机接入时，需要对用于发送随机接入前导码的非授权信道进行LBT检测，在LBT检测的结果为失败时，对前导码传输计数器的计数值进行加一操作并确定前导码传输计数器的计数值是否已达到前导码最大传输次数，若达到前导码最大传输次数，则可执行RLF处理，其中，前导码最大传输次数基于待传输业务的业务类型或者QCI确定，由此可以实现支持NR-U的UE可根据不同的业务类型选择前导码最大传输次数，例如，时延不敏感的业务类型的前导码最大传输次数可以为一个比较大的值，进而可以避免在非授权信道比较繁忙的情况下过早地触发RLF导致随机接入失败；而时延敏感的业务类型的前导码最大传输次数可以为一个比较小的值，进而可以使得UE在非授权信道比较繁忙的情况下尽早地选择其它方式接入网络，提高接入成功率和业务数据的传输效率。
下面以具体实施例来说明本公开实施例提供的技术方案。
图2是根据一示例性实施例示出的另一种接入控制方法的流程图；本实施例利用本公开实施例提供的上述方法，以用户设备如何基于待传输业务的业务类型或QCI执行基于NR的非授权频谱接入为例进行示例性说明，如图2所示，包括如下步骤：
在步骤210中，确定待检测信道进行LBT检测的结果，待检测信道为用于发送随机接入前导码的非授权信道，执行步骤220和步骤230。
在步骤220中，若LBT检测的结果为成功，发送随机接入前导码。
在一实施例中，在确定LBT检测的结果为成功时，指示用户设备可以在待检 测信道上发送MSG1，并在其中携带随机接入前导码，以便完成随机接入。
在步骤230中，若LBT检测的结果为失败，对前导码传输计数器进行加一操作并且确定前导码传输计数器的计数值。
在一实施例中，在由于LBT检测的结果为失败而导致不能发送随机接入前导码时，会同时增加前导码传输计数器的计数值，在前导码传输计数器的计数值达到前导码最大传输次数时，则通常意味着此次随机接入过程失败，因此在由于LBT检测的结果为失败而对前导码传输计数器进行加一操作后需要确定前导码传输计数器的计数值是否已达到前导码最大传输次数。
在步骤240中，若前导码传输计数器的计数值达到前导码最大传输次数，执行无线链路失败处理。
在一实施例中，执行RLF处理的具体操作可以参见相关技术中触发RLF的操作，如可以向网络侧发送RLF报告，或者尝试接入其他基站。
在一实施例中，前导码最大传输次数与待传输业务的业务类型或者服务质量等级标识之间存在对应关系。
在一实施例中，用户设备可以通过两种方式获取前导码最大传输次数与待传输业务的业务类型或者服务质量等级标识之间的对应关系：
方式一：根据通信协议规定，确定前导码最大传输次数与待传输业务的业务类型或者服务质量等级标识之间的对应关系。
方式二：根据基站的动态配置，获取前导码最大传输次数与待传输业务的业务类型或者服务质量等级标识之间的对应关系。
在一实施例中，由于不同的基站所支持的业务类型可能不相同，因此基站可以根据自己所支持的业务类型来向动态地配置上述对应关系，比如基站1只支持业务1，则可通过SIB1广播业务1对应的前导码最大传输次数，而基站2支持业务1和业务2，则可通过SIB1广播业务1和业务2分别对应的前导码最大传输次数。其中，基站所广播的对应关系通常可通过通信协议预先规定好。
本实施例中，用户设备在进行随机接入时，通过在确定待检测信道进行LBT检测的结果为失败后，对前导码传输计数器进行加一操作，进而可在待检测信道的前导码传输计数器的计数值超过前导码传输计数器所能计数的前导码最大传输次数时触发RLF，并且由于UE可根据不同的业务选择前导码最大传输次数，因此可提高随机接入的成功率。
图3是根据一示例性实施例示出的另一种接入控制方法的流程图；本实施例利 用本公开实施例提供的上述方法，以用户设备如何执行基于NR的非授权频谱接入为例进行示例性说明，如图3所示，包括如下步骤：
在步骤310中，确定待检测信道进行LBT检测的结果，待检测信道为用于发送随机接入前导码的非授权信道。
在步骤320中，若LBT检测的结果为失败，对前导码传输计数器进行加一操作并且确定前导码传输计数器的计数值。
在步骤330中，确定前导码传输计数器的计数值是否达到前导码最大传输次数，若达到前导码最大传输次数，执行步骤340，若没有达到前导码最大传输次数，执行步骤310。
在步骤340中，执行无线链路失败处理。
在一实施例中，如果UE执行的前导码传输计数器的计数值已达到前导码最大传输次数，则可触发RLF，并执行无线链路失败处理操作，例如，上报基站RLF报告，或者尝试接入其他基站等。
在一实施例中，如果前导码传输计数器没有达到前导码最大传输次数，则继续对待检测信道进行LBT检测。
在一实施例中，前导码最大传输次数与待传输业务的业务类型或者服务质量等级标识之间存在对应关系。
在一实施例中，业务类型还可以为用户设备的待传输业务的具体类型，例如，待传输业务为视频业务，或者待传输业务为普通的上网服务，等等。每一种业务的QCI等级可以由通信协议规定。
本实施例中，用户设备可基于待传输业务的业务类型，选择前导码最大传输次数，用以提高支持NR-U的用户设备在非授权频段资源竞争激烈时执行随机接入的接入成功率，进而避免在待传输业务的业务类型为时延敏感型业务时，UE在非授权信道比较繁忙的情况下尽早地选择其它方式接入网络，或者在待传输业务的业务类型为时延不敏感型业务时，UE在非授权信道比较繁忙的情况下过早地触发RLF导致随机接入失败。
图4是根据一示例性实施例示出的一种接入控制方法的流程图；该接入控制方法可以应用在支持新空口的非授权频段接入的基站上，本实施例结合图1B进行示例性说明，如图4所示，该接入控制方法包括以下步骤410-420：
在步骤410中，基于所支持的业务类型，确定第一系统消息块，第一系统消息块中携带有业务类型与前导码最大传输次数之间的对应关系或服务质量等级标识与前 导码最大传输次数之间的对应关系。
在一实施例中，由于不同的基站所支持的业务类型可能不相同，因此基站可以根据自己所支持的业务类型来向动态地配置上述对应关系，比如基站1只支持业务1，则可在SIB1中携带业务1所对应的前导码最大传输次数，而基站2支持业务1和业务2，则可在SIB1中携带业务1和业务2分别对应的前导码最大传输次数。在另一实施例中，基站还可基于所支持的业务类型对应的QCI，直接在SIB1中携带所支持的业务的QCI以及对应的前导码最大传输次数。
在步骤420中，广播第一系统消息块。
在一示例性场景中，如图1B所示，以移动网络为5G网络并且基站为演进型基站(eNB)为例进行示例性说明，在图1B所示的场景中，包括eNB10、UE20，其中，eNB10和UE20均支持NR-U，eNB10可通过SIB1广播所支持业务的业务类型与前导码最大传输次数之间的对应关系或服务质量等级标识与前导码最大传输次数之间的对应关系，由此可以使得准备接入eNB10的UE20在准备进行随机接入时，基于待传输业务的业务类型选择前导码最大传输次数，进而提高随机接入的成功率。
本实施例中，通过上述步骤410-420，基站可通过SIB1广播所支持业务类型对应的前导码最大传输次数，实现向UE动态配置业务类型或服务质量等级标识对应的前导码最大传输次数，有助于提高U E随机接入的成功率。
