Description

自主上行传输方法、装置以及通信系统 技术领域
本发明涉及通信领域，特别涉及一种自主上行传输方法、装置以及通信系统。
背景技术
在新无线工作项目描述(New Radio Work Item Description，NR WID)中，提出了新无线(New Radio，NR)与长期演进(Long Term Evolution，LTE)共存的机制，在该共存机制中，支持在LTE载波内LTE上行和NR上行的共存，以及在LTE载波内LTE下行和NR下行的共存。也即，在LTE载波内，用户设备(User Equipment，UE)可以进行基于NR的上行传输和基于LTE的上行传输，并且，UE可以接收基于NR的下行数据和基于LTE的下行数据。在NR WID中，还为上述共存机制定义了至少一个频带组合(NR频带和LTE频带)，该频带组合至少满足以下条件：1)最小化对NR物理层设计的影响，确保共存；2)不影响工作在与NR共存的LTE载波上的legacy LTE设备(如网络设备eNB服务的UE)的能力；3)UE不一定必须支持LTE载波内NR和LTE的同时连接。
另一方面，假设LTE的网络设备(如eNB)和NR的网络设备(如gNB)进行了网络同步，并且支持单上行传输解决方案，则当UE激活不同频率上的多个上行载波时(至少有一个LTE上行载波和至少一个不同频率上的NR上行载波)，UE可以使用LTE上行载波和NR上行载波的时间切换(time-switching)，此时，LTE上行载波和NR上行载波的上行传输定时模式在eNB和gNB之间半静态地共享。此外，在单上行传输解决方案中，UE可以同时接收NR下行载波和LTE下行载波上的信号。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，为了确保UE支持单上行传输解决方案，可以有以下两种方法：
方法1：基于动态调度，也即，网络侧协调上行传输定时模式，并基于该模式， 分别进行上行传输的调度，保证UE单上行传输，即在某一时刻，UE仅在一个无线接入技术(RAT)上进行上行传输，例如在NR上进行上行传输，或者在LTE上进行上行传输；
方法2：显式通知上行传输定时模式，也即，网络侧协调上行传输定时模式，并将该模式告知UE，保证UE单上行传输，即在某一时刻，UE仅在一个无线接入技术(RAT)上进行上行传输，例如在NR上进行上行传输，或者在LTE上进行上行传输。
然而，无论上述方法1还是上述方法2，当UE在其中一个RAT上进行上行传输时，都无法在另外一个RAT上进行传输。这意味着一个RAT上进行上行传输最大的等待时间取决于另一个RAT上进行上行传输的持续时间。这可能无法满足NR中高可靠低延时通信(Ultra Reliable and Low Latency Communication，URLLC)业务的时延需求，对LTE上行传输也会造成影响，例如，对于预分配了探测参考信号(Sounding Reference Signal，SRS)资源的LTE，其预分配的SRS资源与方法1或方法2冲突，使得UE无法传输SRS。
为了解决上述问题的至少一个，本发明实施例提供了一种自主上行传输方法、装置以及通信系统。

下面结合附图对本发明的各种实施方式进行说明。这些实施方式只是示例性的，不是对本发明的限制。
实施例1
本实施例提供了一种自主上行传输方法，该方法应用于网络设备，例如eNB(LTE中的基站)、gNB(NR中的基站)等，图2是该方法的流程图，请参照图2，该方法包括：
步骤201：网络设备为用户设备配置自主改变进行上行传输的无线接入技术的能力，以便所述用户设备根据所述能力自主改变进行上行传输的无线接入技术。
在本实施例中，网络设备为用户设备配置了能够自主改变进行上行传输的无线接 入技术(Radio Access Technology，RAT)的能力，由此，该用户设备不再基于网络侧的上行调度或者网络侧发送的上行传输定时模式决定进行上行传输的无线接入技术，而是根据该能力自主决定进行上行传输的无线接入技术，增加了用户设备侧选择无线接入技术的灵活性，用户设备可以根据自己的业务特点或业务类型决定无线接入技术，确保了业务上行传输的时延要求，同时实现了周期性业务的上行传输。
在本实施例中，无线接入技术例如为NR技术或者为LTE技术，通过本实施例的方法，UE可以自主选择是在NR上进行上行传输还是在LTE上进行上行传输。
在本实施例的一个实施方式中，如图2所示，该方法还可以包括：
步骤202：所述网络设备为所述用户设备配置所述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数。
在本实施方式中，除了配置上述能力，网络设备还可以为用户设备配置上述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数，由此，用户设备可以在网络设备为其配置了上述能力的情况下，结合该持续时间和/或次数和/或资源数，自主改变进行上行传输的无线接入技术。关于用户设备的处理，将在后面的实施例中进行说明。
在本实施例的另一个实施方式中，网络设备仅为用户设备配置了前述能力，而上述持续时间和/或次数和/或资源数也可以是预先定义的，或者预配置的，或者默认的，或者网络设备和用户设备已经协商好的。由此，用户设备根据网络侧为其配置的该能力，结合预定义或预配置或默认或协商的上述持续时间和/或次数和/或资源数，自主改变进行上行传输的无线接入技术。
在本实施例的再一个实施方式中，网络设备也可以不直接为用户设备配置上述能力，而是通过为用户设备配置上述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数，来隐式地指示用户设备上述能力，由此，用户设备可以根据网络设备的该配置，自主改变进行上行传输的无线接入技术。
在本实施例的一个实施方式中，如图2所示，该方法还可以包括：
步骤203：所述网络设备为所述用户设备配置所述能力的限制条件。
在本实施方式中，除了配置上述能力，和/或配置上述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数以外，网络设备还可以为用户设备配置该能力的限制条件，例如该能力所适用的业务和/或业务类型，再例如该能力所适用的逻辑信 道或逻辑信道优先级或逻辑信道组或逻辑信道组优先级，等等。由此，用户设备可以基于该限制条件，决定是否自主改变进行上行传输的无线接入技术。
例如，当用户设备被配置了上述能力和/或上述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数之后，如果用户设备的业务和/或业务类型在上述限制条件的范围内，则用户设备可以自主更换进行上行传输的无线接入技术，相反，如果用户设备的业务和/或业务类型不在上述限制条件的范围内，也即其业务和/或业务类型不是上述能力所适用的业务和/或业务类型，则用户设备依旧根据网络侧的上行调度或者网络侧发送的上行传输定时模式选择进行上行传输的无线接入技术。
再例如，当用户设备被配置了上述能力和/或上述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数之后，如果用户设备的业务属于上述限制条件所限定的逻辑信道或逻辑信道优先级或逻辑信道组或逻辑信道组优先级的范围，则用户设备可以自主更换进行上行传输的无线接入技术，相反，如果用户设备的业务不属于上述限制条件所限定的范围，则用户设备依旧根据网络侧的上行调度或者网络侧发送的上行传输定时模式选择进行上行传输的无线接入技术。
在本实施例中，对上述步骤201-203的执行顺序不作限制，这三个步骤可以并行执行，也可以以任意可实施的方式执行。
在本实施例中，网络设备可以通过高层信令为用户设备配置上述能力，以半静态地通知用户设备其是否具备这种能力；也可以通过底层信令为用户设备配置和/或激活(或去激活)上述能力，以动态地通知用户设备其是否具备这种能力。并且，网络设备可以通过上述高层信令中的专用信令和/或广播信令为用户设备配置这种能力，但本实施例并不以此作为限制。
在本实施例中，网络设备可以通过高层信令为用户设备配置上述持续时间和/或次数和/或资源数，以半静态地通知用户设备其具备这种能力的持续时间和/或次数和/或资源数，和/或，半静态地通知用户设备自主上行传输的持续时间和/或次数和/或资源数。并且，网络设备可以通过上述高层信令中的专用信令和/或广播信令为用户设备配置上述持续时间和/或次数和/或资源数。
在本实施例中，网络设备还可以与其他网络设备交互上述能力，和/或交互上述持续时间和/或次数和/或资源数，和/或交互上述限制条件。由此，网络设备可以据此对用户设备进行调度。
通过本实施例的方法，可以确保业务上行传输的时延需求，同时实现了周期性业务的上行传输。
实施例2
本实施例提供了一种自主上行传输方法，该方法应用于用户设备(UE)，其是对应实施例1的方法的UE侧的处理，其中与实施例1相同的内容不再重复说明。图3是该方法的流程图，请参照图3，该方法包括：
步骤301：用户设备根据网络侧配置的自主改变进行上行传输的无线接入技术的能力，自主改变进行上行传输的无线接入技术。
在本实施例中，如前所述，网络设备为用户设备配置了上述能力，由此，用户设备可以不再响应网络侧的上行调度或者网络侧发送的上行传输定时模式，而自主改变进行上行传输的无线接入技术。
在本实施例的一个实施方式中，网络侧还为用户设备配置了上述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数，则如图3所示，该方法还包括：
步骤302：所述用户设备进一步根据网络侧配置的所述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数，自主改变进行上行传输的无线接入技术。
在本实施方式中，用户设备可以在上述持续时间内不响应网络侧的上行调度或者忽略接收到的上行传输定时模式，自主改变进行上行传输的无线接入技术。
在本实施方式中，用户设备可以在没有达到自主改变进行上行传输的无线接入技术的次数上限的情况下，不响应网络侧的上行调度或者忽略接收到的上行传输定时模式，自主改变进行上行传输的无线接入技术。可选的，用户设备还可以统计自主改变进行上行传输的无线接入技术的次数，以便在没有达到次数上限的情况下，继续自主改变进行上行传输的无线接入技术。
在本实施方式中，用户设备可以在没有达到自主改变进行上行传输的无线接入技术的资源数上限的情况下，不响应网络侧的上行调度或者忽略接收到的上行传输定时模式，自主改变进行上行传输的无线接入技术。
通过本实施例的方法，用户设备可以在网络设备或其他网络设备对其进行了上行调度的情况下，不响应该上行调度，而是根据上述配置自主改变进行上行传输的无线接入技术。
例如，在一个场景中，基于动态调度，网络侧不向用户设备通知上行传输定时模式。则在网络侧为用户设备配置了上述能力和/或上述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数的情况下，当一个RAT上有动态上行调度时，用户设备基于网络侧配置的上述能力，不响应该动态调度，而是在另一个RAT上进行上行传输。由此通过自主改变RAT实现了上行传输。
通过本实施例的方法，用户设备可以在接收到网络设备发送的上行传输定时模式的情况下，不考虑该上行传输模式，而是根据上述配置自主改变进行上行传输的无线接入技术。
例如，在另一个场景中，网络侧显示通知用户设备上行传输定时模式。则在网络侧为用户设备配置了上述能力和/或上述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数的情况下，当基于上行传输定时模式，用户设备应该在一个RAT上进行上行传输时，该用户设备可以基于网络侧配置的上述能力，忽略该上行传输定时模式，而在另一个RAT进行上行传输。由此通过自主改变RAT实现了上行传输。
在本实施例的另一个实施方式中，网络侧还为用户设备配置了上述能力的限制条件，例如，所述能力所适用的业务和/或业务类型，再例如，所述能力所适用的逻辑信道或逻辑信道优先级或逻辑信道组或逻辑信道组优先级，则如图3所示，该方法还包括：
步骤303：所述用户设备进一步根据网络侧配置的所述能力的限制条件决定是否自主改变进行上行传输的无线接入技术。
在本实施例中，用户设备可以自主改变进行上行传输的无线接入技术，也可以根据网络设备配置的上述能力的限制条件来决定是否自足改变进行上行传输的无线接入技术。例如，在用户设备被配置了上述能力(步骤301)和/或上述能力和/或允许自主上行传输的持续时间和/或次数和/或资源数(步骤302)之后，用户设备自行决定是否改变进行上行传输的无线接入技术。再例如，网络设备还为用户设备配置了上述能力的限制条件(步骤303)，用户设备在被配置了上述能力和/或上述能力(步骤301)和/或允许自主上行传输的持续时间和/或次数和/或资源数(步骤302)之后，根据该限制条件决定是否改变进行上行传输的无线接入技术。
在本实施例中，对上述步骤301-303的执行顺序不作限制，这三个步骤可以并行执行，也可以以任意可实施的方式执行。
在本实施例中，上述网络侧可以是指为该用户设备提供服务的网络设备，例如在NR场景下的gNB，再例如在LTE场景下的eNB。
通过本实施例的方法，可以确保业务上行传输的时延需求，同时实现了周期性业务的上行传输。
