Description

上行传输配置的配置和获取方法、装置以及通信系统 技术领域
本发明涉及通信领域，特别涉及一种上行传输配置的配置和获取方法、装置以及通信系统。
背景技术
随着社会的不断发展和进步，通信业务需求的持续增长为未来无线通信系统提出了挑战。为了支持快速增长的业务量和日益繁多的新业务，全球各研究机构及标准化组织先后启动了第五代(5G)无线通信系统研究。其中，第三合作伙伴计划(3GPP，3rd Generation Partnership Project)在研究过程中定义了大规模机器类型通信(mMTC，massive Machine Type Communications)、增强的移动宽带(eMBB，enhanced Mobile Broadband)和超可靠低时延通信(URLLC，ultra-Reliable Low Latency Communication)等多种应用场景。
随机接入过程是用户设备(UE，User Equipment)进行初始接入的必经过程之一。UE通过小区搜索并接收小区系统信息获取小区的随机接入资源配置集合，确定随机接入前导信号及随机接入物理时频资源，在相应物理时频资源发送随机接入前导信号以发起随机接入过程。
图1是长期演进时分双工(LTE TDD，Long Term Evolution Time Division Duplexing)系统中物理随机接入信道(PRACH，Physical Random Access Channel)及随机接入前导信号(preamble)配置相关的信息，如图1所示，UE从通过小区搜索获得的主同步信号(PSS，Primary Synchronization Signal)和/或辅同步信号(SSS，secondary synchronization signal)中可以获得主信息块(MIB，Master Information Block)信息，该MIB信息中包含了下行带宽(DL BW，Downlink Bandwidth)信息和帧号(SFN，System Frame Number)信息等，基于MIB中包含的信息，UE进一步监听PDCCH，获取SIB1信息，该SIB1信息中包含了TDD上下行配置信息，其他系统信息块(包括第二系统信息块(SIB2，System Information Block 2))调度信息等，进而可以获得SIB2信息，该SIB2信息中包含了UE进行随机接入的配置信息，例如前导序列集合配置、PRACH配置索引、PRACH频偏等，其中，PRACH配置索 引和PRACH频偏即指示了上行传输时频资源。
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，在现有随机接入资源配置机制中，UE需要接收MIB、SIB1、SIB2才能最终确定随机接入资源集合，因此，UE获取配置信息的时延较大，难以满足URLLC等应用场景或业务的超低时延要求。同时，现有LTE TDD系统中预定义了多种上下行配置方式，随机接入的物理时频资源配置与TDD上下行配置相匹配，这种半静态的耦合配置方式大大限制了系统资源配置的灵活性，难以支持高灵活度的动态上下行调度(例如dynamic TDD)。

在本实施例中，上行传输配置可以包括：物理时频资源(位置和/或大小)，还可以包括例如随机接入前导信号(preamble，简称为前导码)、序列、码字、交织和/或映射方式、参考信号、空域资源、传输功率等信息(资源或配置)的一项或多项。并且，上述物理时频资源和/或上述前导码、序列、码字、交织和/或映射方式、参考信号、空域资源、传输功率的一项或多项可以通过配置方式1和/或配置方式2和/或配置方式3和/或配置方式4联合配置或者独立配置。例如，物理时频资源及preamble通过配置方式1联合配置。再例如，物理时频资源通过配置方式1配置，而preamble通过配置方式4配置。
在本实施例中，通过上述配置方式1配置的上行传输配置是静态的，并且是小区专用的，也即小区内的所有UE都可以使用。并且，基站通过配置方式1配置的上行传输配置可用于时延要求较高的应用场景或业务，UE接收同步信号后即可获知该配置方式1下的上行传输配置。
下面以通过小区标识与上行传输配置的固定映射关系配置上行传输配置为例对配置方式1进行说明。

表1
Figure PCTCN2016099232-appb-000002
如表1所示，UE根据小区标识的模值可以确定该小区基于配置方式1的上行传 输配置。
图3是上行传输配置为#0(小区标识的模值为0)的一个示例，图4是上行传输配置为#1(小区标识的模值为1)的一个示例。需要指出的是，图3和图4只表征了物理时频资源的配置。
在本实施例中，通过上述配置方式2配置的上行传输配置也是静态的，并且是小区专用的，也即小区内的所有UE都可以使用。同样的，基站配置方式2配置的上行传输配置可用于时延要求较高的应用场景或业务，UE接收主信息块(MIB)后即可获知该配置方式2下的上行传输配置。
在本实施例中，通过上述配置方式3配置的上行传输配置是半静态的，并且是小区专用的，也即小区内的所有UE都可以使用。在配置方式3中，系统消息可以是主信息块(MIB)也可以是系统信息块(SIB)。并且，基站通过配置方式3配置的上行传输配置可用于没有过高时延要求的一般应用场景或业务。在该配置方式下，可以结合系统消息的广播周期或者变更方式来实现该上行传输配置的半静态配置。
图5是基站通过配置方式3配置的上行传输配置的一个示例。
在本实施例中，由于系统消息(MIB和SIB)中包含的信息是小区级别的信息，其中包含的信息对小区内所有UE有效。基站通过不断广播MIB和SIB告知UE小区的配置，以支持UE接入小区并在小区中正常工作。
在本实施例中，不同类型的系统消息可根据信息重要性或时效性配置不同周期进行广播，或者根据是否有UE需要获取该信息进行广播，或者结合这两种方式使用。根据该系统消息的广播周期和/或变更方式，可以实现上述配置方式3下的上行传输配置的半静态配置。
在本实施例中，系统消息的变更方式包括但不限于以下示例：
1)根据其广播周期变更；系统消息在每次广播机会都可能变更，UE周期性接收系统消息；
2)动态更新；系统消息在任意广播机会都可能变更，基站在系统消息变更前指示UE获取新的系统消息；以及
3)设置变更周期；系统消息的内容根据变更周期进行更新，基站在系统消息变更前指示UE获取新的系统消息。
根据该系统消息的变更方式，可以实现上述配置方式3下的上行传输配置的半静 态配置。
图6是基于变更周期更新上行传输配置的一个示例，如图6所示，在第n个变更周期，上行传输配置的配置为#1，基站通知UE系统信息将在下一变更周期变化；在第n+1个变更周期，信息进行了更新，UE根据基站的指示接收更新的系统消息，获知上行传输配置的配置变更为#2，由此实现了上行传输配置的半静态配置。需要说明的是，图6的上行传输配置的变更方式只是示例，不要求上行传输配置在每个变更周期都重新配置。
在本实施例中，通过上述配置方式4配置的上行传输配置是动态的，并且是用户专用的。这种配置方式下配置的上行传输配置可用于例如连接态UE的切换、UE丢失上行同步时的上行定时调整或进行上行定位操作等。并且，多个UE可以共用相同的配置，或者为UE配置专用配置。这里的物理层动态信令例如为物理层控制信道信令等，本实施例并不以此作为限制。
图7是基站通过配置方式4配置的上行传输配置的一个示例。类似的，图7也是仅以物理时频资源作为上行传输配置为例。
在本实施例中，基站可以结合上述四种配置方式(可以选择其中一种或者多种)来配置上行传输配置，不同的配置方式配置的上行传输配置可以有交集，也可以没有交集。
图8是基站同时采用上述四种配置方式时的一个示例，其中，由于配置方式1和配置方式2所配置的上行传输配置都是静态的，在本示例中，将这两种配置方式所配置的上行传输配置合并。
在本实施例中，上述物理时频资源用于传输随机接入前导信号(preamble)，和/或合并传输随机接入前导信号(preamble)及传输接入所需数据，和/或合并传输随机接入前导信号(preamble)及业务数据，和/或传输业务数据。这里，接入所需数据例如为用户设备标识(UE ID)等，这里，业务数据例如为高时延要求业务的业务数据(grant-free/grant-based)等。也就是说，本实施例的配置方法可用于随机接入和/或业务数据传输场景。
例如，在一般随机接入过程中，UE需要发送preamble。再例如，在简化的随机接入过程中，UE可合并发送preamble及UE ID等数据信息。再例如，业务数据传输可以包括基于上行授权(grant-based)的上行业务数据传输，还可以包括基于非授权 (grant-free)的上行业务数据传输。基于非授权(grant-free)的上行业务数据传输方式中可能还需要序列、码字、参考信号等资源配置，若UE获得了上行同步，则可直接传输上行业务数据，若UE未获得上行同步(如理想状态下)，则UE需要合并传输随机接入前导信号(preamble)及上行业务数据。
在本实施例的一个实施方式中，基站支持多个信号表征(Numerology)，Numerology用于表示一个无线信号的一组参数，例如子载波间隔、循环前缀长度、符号长度等。在LTE/LTE-A系统中，小区接入过程是基于每个用户设备都支持相同的Numerology的假设进行设计的，但是在未来无线接入系统中，每个用户设备可能因场景的不同会支持不同的Numerology。
图9为频分复用(FDM)系统中，三种Numerology(f0，2*f0，4*f0)的示例，图10是时分复用(TDM)系统中，三种Numerology(f0，2*f0，4*f0)的示例，图11是混合(hybrid)系统中，三种Numerology(f0，2*f0，4*f0)的示例。
在本实施方式中，针对不同的Numerology，可以配置各自的上行传输配置，也可以配置共用的上行传输配置。例如，用于初始接入的上行传输配置相同，而用于上行定时调整、定位等的上行传输配置则针对各Numerology分别配置。再例如，各Numerology共用静态或半静态的上行传输配置，而动态的上行传输配置则针对各Numerology分别配置。在本实施方式中，配置方式可以采用上述配置方式1-4中的任意一种或多种。
在本实施方式中，基站可以通过上述配置方式1-4的至少一种为不同的Numerology配置各自专用的上行传输配置。或者，基站也可以通过上述配置方式1-4的至少一种为两种或两种以上的Numerology配置共用的上行传输配置。或者，基站也可以通过上述配置方式1-3中的至少一种为两种或两种以上的Numerology配置共用的静态和/或半静态上行传输配置，并且，通过配置方式4为不同的Numerology配置各自专用的动态的上行传输配置。或者，基站还可以通过上述配置方式1-2中的至少一种为两种或两种以上的Numerology配置共用的静态的上行传输配置，并通过配置方式3-4中的至少一种为不同的Numerology配置各自专用的半静态和/或动态的上行传输配置。
下面以图9所示的多Numerology为例，对针对各Numerology的上行传输配置的指示方式进行说明。
在一个实施方式中，基站可以通过不同Numerology各自的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令分别指示上行传输配置。如图12所示，对于Numerology#1、Numerology#2、Numerology#3，分别指示了各自的上行传输配置。
在另一个实施方式中，基站可以通过参考信号表征(reference Numerology)上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令显式或隐式地指示参考Numerology及其他Numerology的上行传输配置。如图13所示，Numerology#2为参考Numerology，通过本实施例的方法显式或隐式地指示Numerology#2及其他Numerology(Numerology#1和Numerology#3)的上行传输配置。
在另一个实施方式中，基站可以通过参考Numerology上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令指示参考Numerology的上行传输配置，通过参考Numerology上的同步信号和/或小区标识和/或参考信号和/或系统消息显式或隐式指示其他Numerology的静态或半静态的上行传输配置，并且，通过其他Numerology各自的物理层动态信令分别指示其他Numerology的各自的动态的上行传输配置。如图14所示，Numerology#2为参考Numerology，通过Numerology#2上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令指示Numerology#2的上行传输配置，通过Numerology#2上的同步信号和/或小区标识和/或参考信号和/或系统消息显式或隐式指示其他Numerology(Numerology#1和Numerology#3)的静态或半静态的上行传输配置；并且，通过其他Numerology各自的物理层动态信令分别指示其他Numerology各自的动态的上行传输配置。
在另一个实施方式中，基站可以通过参考Numerology上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令指示参考Numerology的上行传输配置，通过参考Numerology上的同步信号和/或小区标识和/或参考信号和/或系统消息显式或隐式指示其他Numerology的静态的上行传输配置，并且，通过其他Numerology各自的系统消息或物理层动态信令分别指示其他Numerology各自的半静态或动态的上行传输配置。如图15所示，Numerology#2为参考Numerology，通过Numerology#2上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令指示Numerology#2的上行传输配置，通过Numerology#2上的同步信号和/ 或小区标识和/或参考信号和/或系统消息显式或隐式指示其他Numerology的静态的上行传输配置，并且，通过其他Numerology各自的系统消息或物理层动态信令分别指示其他Numerology各自的半静态或动态的上行传输配置。
通过本实施方式的上行传输配置的配置方法，可以实现多Numerology场景下的上行传输配置的灵活配置。
在本实施例的另一个实施方式中，该上行传输配置的配置方法可以应用于多载波系统，系统中的用户设备支持单个载波或者多个载波，则与多Numerology的情况类似，基站可以通过不同载波各自的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令分别指示上行传输配置；基站也可以通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令显式或隐式地指示参考载波及其他载波的上行传输配置；基站还可以通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令指示参考载波的上行传输配置，通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息显式或隐式指示其他载波的静态或半静态的上行传输配置，并且，通过其他载波各自的物理层动态信令分别指示其他载波各自的动态的上行传输配置；基站还可以通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令指示参考载波的上行传输配置，通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息显式或隐式配置其他载波的静态的上行传输配置，并且，通过其他载波各自的系统消息或物理层动态信令分别指示其他载波各自的半静态或动态的上行传输配置。具体指示方式与图12-15类似，此处不再赘述。
通过本实施方式的上行传输配置的配置方法，可以实现多载波系统中的上行传输配置的灵活配置。
在本实施例的又一个实施方式中，该上行传输配置的配置方法可以应用于超小区(Hyper cell)场景，多个发送接收点(TRP)组成一个Hyper cell，如图16所示，则与多Numerology的情况类似，基站可以通过不同TRP各自的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令分别指示上行传输配置；该基站也可以通过参考TRP上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令显式或隐式地指示参考TRP及其他TRP的上行传输配置；该基站还可以通过参考TRP上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物 理层动态信令配置参考TRP的上行传输配置，通过参考TRP上的同步信号和/或小区标识和/或参考信号和/或系统消息显式或隐式指示其他TRP的静态或半静态的上行传输配置，并且，通过其他TRP各自的物理层动态信令分别指示其他TRP各自的动态的上行传输配置；该基站还可以通过参考TRP上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令指示参考TRP的上行传输配置，通过参考TRP上的同步信号和/或小区标识和/或参考信号和/或系统消息显式或隐式指示其他TRP的静态的上行传输配置，并且，通过其他TRP各自的系统消息或物理层动态信令分别指示其他TRP各自的半静态或动态的上行传输配置。具体配置方式与图12-15类似，此处不再赘述。
通过本实施方式的上行传输配置的配置方法，可以实现多TRP场景下的上行传输配置的灵活配置。
通过本实施例的方法，能够提高上行传输配置的配置灵活性并适应不同场景及业务的时延及可靠性要求。
实施例2
本实施例提供了一种上行传输配置的获取方法，该方法应用于用户设备，是与实施例1的方法对应的用户设备侧的处理，其中，与实施例1相同的内容不再重复说明。
图17是本实施例的方法的一个实施方式的示意图，如图16所示，该方法包括：
步骤1701：用户设备从基站配置的上行传输配置中获取上行传输配置，所述基站通过以下配置方式的至少一种配置所述上行传输配置：
配置方式1：通过同步信号和/或小区标识和/或参考信号与上行传输配置的固定映射关系配置上行传输配置；
配置方式2：通过主信息块(MIB)配置上行传输配置；
配置方式3：通过系统消息(MIB或SIB)配置上行传输配置；
配置方式4：通过物理层动态信令配置上行传输配置。
在本实施例中，关于各个配置方式的使用和上行传输配置的含义，已经在实施例1中做了详细说明，其内容被合并于此，此处不再赘述。
在本实施例中，根据UE状态及业务需求，UE可以选用基站通过不同配置方式 配置的上行传输配置或由基站专门为其配置的上行传输配置进行上行传输。
在本实施例的一个实施方式中，当触发事件为用户设备需要建立无线连接且要求时延低于T1(ms)时，该用户设备可以通过同步信号或者主信息块获取基站通过上述配置方式1或者配置方式2配置的上行传输配置，从该上行传输配置中选择资源和/或信息等进行上行传输。
在本实施例的另一个实施方式中，当触发事件为用户设备需要建立无线连接且不要求时延低于T1(ms)时，该用户设备可以通过系统消息获取基站通过上述配置方式3配置的上行传输配置，从该上行传输配置中选择资源和/或信息等进行上行传输。
在上述两个实施方式中，用户设备需要建立无线连接，例如UE在初始接入时需要建立无线连接，此时，UE会从RRC空闲态转变为RRC连接态；再例如UE在无线链路失败后需要重建无线连接(RRC连接重建过程)；UE需要建立无线连接。
在上述两个实施方式中，在UE需要建立无线连接的情况下，如果要求时延低于T1(ms)，该UE可以从接收到的同步信号中获取基站通过配置方式1配置的上行传输配置，或者从接收到的主信息块中获取基站通过配置方式2配置的上行传输配置，由于通过配置方式1和配置方式2配置的上行传输配置是小区级的，UE在获取了上述上行传输配置后，可以通过竞争的方式选择资源和/或信息进行上行传输；如果不要求时延低于T1(ms)，该UE可以从接收到的系统消息中获取基站通过配置方式3配置的上行传输配置，同样的，由于通过配置方式3配置的上行传输配置是小区级的，UE在获取了上述上行传输配置后，可以通过竞争的方式选择资源和/或信息进行上行传输。
在本实施例的另一个实施方式中，UE在RRC空闲态下，上行数据到达时，如需要上报测量报告或发送用户数据时，且UE被允许通过grant-free方式发送上行数据时，即RACH-free的grant-free传输，UE可以通过同步信号或者主信息块获取基站通过上述配置方式1或者配置方式2配置的上行传输配置，从该上行传输配置中选择资源和/或信息等进行上行传输，UE也可以通过系统消息获取基站通过上述配置方式3配置的上行传输配置，从该上行传输配置中选择资源和/或信息等进行上行传输。
在本实施例的另一个实施方式中，当触发事件为用户设备需要传输上行数据但上行丢失同步时，该用户设备可以通过同步信号或者主信息块或者系统消息获取基站通过上述配置方式1或配置方式2或配置方式3配置的上行传输配置，从该上行传输配 置中选择资源和/或信息进行上行传输。
在本实施方式中，当UE处于RRC连接态，并且上行数据到达时，如需要上报测量报告或发送用户数据时，如果上行处于不同步状态或没有可用的物理上行链路控制信道(PUCCH，Physical Uplink Control Channel)资源用于调度请求(SR，Scheduling request)传输时(此时允许已经处于上行同步状态的UE使用RACH来替代SR的作用)，或者，如果数据传输时延要求较高且允许UE通过grant-free方式发送数据时(即RACH-based的grant-free传输)，则UE在通过的同步信号或主信息块或系统消息中获取到基站通过上述配置方式1或配置方式2或配置方式3配置的上行传输配置后，由于该上行传输配置是小区级的，可以通过竞争的方式选择资源和/或信息进行上行传输。
在本实施例的再一个实施方式中，当触发事件为用户设备需要进行切换或上行定时同步时，该用户设备可以获取通过配置方式4配置的上行传输配置，并从该上行传输配置中选择资源和/或信息进行上行传输。
在本实施方式中，例如UE需要通过切换与新的小区建立上行同步时，UE可以根据基站的指示选择资源和/或信息进行上行传输；再例如UE在RRC连接态下行数据到达时，如需要回复ACK/NACK时，如果上行处于不同步的状态，UE可以根据基站的指示选择资源和/或信息进行上行传输；再例如UE在RRC连接态，基站想定位UE时，可以通过发送上述指示信息指示UE选择资源和/或信息进行上行传输。
在本实施例中，时延要求可以量化为某个具体的值，当时延要求大于预先设定的阈值时，认为时延要求较高，当时延要求小于该阈值时，认为时延要求不高。上述只是举例说明，在具体实施过程中，可以根据实施情况设定该时延要求的基准，并以该基准作为参考来衡量时延要求是较高还是不高，此处不再赘述。
通过本实施例的方法，能够提高上行传输配置的配置灵活性并适应不同场景及业务的时延及可靠性要求。
实施例3

在本实施例的另一个实施方式中，在多载波系统中，配置单元1801可以通过不同载波各自的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令分别指示上行传输配置；也可以通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令显式或隐式地指示参考载波及其他载波的上行传输配置；还可以通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令指示参考载波的上行传输配置，通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息显式或隐式指示其他载波的静态或半静态的上行传输配置，并且，通过其他载波各自的物理层动态信令分别指示其他载波各自的动态的上行传输配置；还可以通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息和/或物理层动态信令指示参考载波的上行传输配置，通过参考载波上的同步信号和/或小区标识和/或参考信号和/或系统消息显式或隐式配置其他载波的静态的上行传输配置，并且，通过其他载波各自的系统消息或物理层动态信令分别指示其他载波各自的半静态或动态的上行传输配置。

实施例4
本实施例提供了一种上行传输配置的获取装置，配置于用户设备中，由于该装置解决问题的原理与实施例2的方法类似，其具体的实施可以参考实施例2的方法的实施，内容相同之处不再重复说明。
图20是本实施例的上行传输配置的获取装置的示意图，如图20所示，该装置2000包括：获取单元2001。
