技术领域
本申请涉及无线通信技术领域，特别涉及一种业务传输方法及装置。
背景技术
目前，多输入多输出(Multi-input Multi-out，MIMO)技术成为了新无线(new radio，NR)系统以及长期演进(long term evolution，LTE)系统等移动通信系统提升系统容量的关键技术。而随着MIMO规格的不断提升，基站配置的天线数量越来越多，基站中的射频通道的数量也随着基站的天线数量成线性的增长。
基站中的一个射频通道包括功率放大器、低噪声放大器、数模转换器、射频芯片以及外围电路等模块，随着射频通道数量的增加，基站的功耗也随之提升。举例来说，基站的天线数量从2增加到64时，基站中的射频通道所包括的器件所对应的功耗将从150瓦提升到600瓦。

其中，应用子系统可作为通信装置的主控制系统或主计算系统，用于运行主操作系统和应用程序，管理整个通信装置的软硬件资源，并可为用户提供用户操作界面。应用子系统可包括一个或多个处理核心。此外，应用子系统中也可包括与其他子系统(例如基带子系统)相关的驱动软件。基带子系统也可包括以及一个或多个处理核心，以及硬件加速器(hardware accelerator，HAC)和缓存等。
图2中，RFFE器件，RFIC 1(以及可选的RFIC 2)可以共同组成射频子系统。射频子系统中包括射频通道，射频通道可以进一步分为射频接收通道(radio frequency receive path)和射频发射通道(radio frequency transmit path)。
射频接收通道可通过天线接收射频信号，对该射频信号进行处理(如放大、滤波和下变频)以得到基带信号，并传递给基带子系统。射频发射通道可接收来自基带子系统的基带信号，对基带信号进行射频处理(如上变频、放大和滤波)以得到射频信号，并最终通过天线将该射频信号辐射到空间中。
具体地，射频发射通道可以包括低噪声放大器(low noise amplifier，LNA)，功率放大器(power amplifier，PA)，混频器(mixer)，本地振荡器(local oscillator，LO)、滤波器(filter)以及数模转换器(digital to analog converter，DAC)等电子器件，这些电子器件可以根据需要集成到一个或多个芯片中。天线有时也可以认为是射频子系统的一部分。

结合前面的描述，如图3所示，为本申请实施例提供的一种业务传输方法流程示意图。图3所示的流程的执行主体可以为网络设备，参见图3，该方法包括：
步骤301：确定第一时间单元的业务量。
第一时间单元可以为一段时间，例如以小时或者分钟为单位，举例来说可以一个时间单元可以为一个小时、10个小时、30分钟等；第一时间单元还可以以传输时间间隔(transmit time interval，TTI)或者时隙(slot)或者子帧(subframe)或者符号或者无线帧等为单位，本申请实施例并不限定。
进一步的，具体如何确定第一时间单元的业务量，本申请实施例并不限定。例如，可以根据历史数据中的业务量对第一时间单元的业务量进行预测，也可以通过神经网络算法推测第一时间单元的业务量等，在此不再逐一举例说明。
第一时间单元具体可以为网络设备配置的，也可以为通信标准中定义的，还可以根据其他方式确定，在此不再赘述。
步骤302：根据所述业务量以及第一映射关系确定在所述第一时间单元内开启第一数量的射频通道。
其中所述第一映射关系包括业务量与射频通道数量的映射关系。第一映射关系的具体实现方式，本申请实施例并不限定，将在后面的实施例中描述，在此不再赘述。
需要说明的是，本申请实施例中，业务量越少，需要开启的射频通道的数量也越少。
步骤303：在所述第一时间单元内，通过所述第一数量的射频通道传输业务，所述业务包括数据信道和参考信号中的至少一种。
图3所示的流程，可以适用于各种不同的MIMO场景，下面分别进行描述。
实施例一：
在实施例一中，将影响通信传输性能的因素可以划分为至少两类，第一类是标准化协议规定的空口传输参数，比如天线端口的配置信息，这类信息需要网络设备通知终端设备，并基于天线端口的配置以及基于配置的传输模式实现MIMO传输，这类信息需要网络设备和终端设备保持统一；第二类是网络设备或终端设备的实现行为，不需要标准化，网络设备或终端设备可以根据自身能力来改变实现方式，但这类的实现是不能影响第一类配置参数的。比如射频通道数的配置，网络设备配置的射频通道数可以多于空口传输参数配置的天线端口数，例如网络设备配置的射频通道数为8，而空口侧配置的天线端口数为4，此 时两个射频通道可以与一个天线端口映射，这样可以将多个射频通道的功率用于发送同一个天线端口对应的信号，提升信号的信噪比从而改善传输性能。
然而通信业务的业务量下降时，如果开启所有的射频通道来发送信号，就造成了功耗浪费，现有射频通道关断的技术一般都要求射频通道关断的同时，关断对应的天线端口的信号发送，保证关断参考信号和数据信道的天线端口的一致性。然而，由于某些场景下，天线端口数不能及时重配，使得网络设备实际发送信号的天线端口和终端设备确定的天线端口不匹配，导致性能下降。因此本申请实施例提供了以下的方法来传输业务，可以实现在关断部分射频通道节省功耗的同时，不关断任何发送信号的天线端口，并通过射频通道与天线端口之间的重新映射，确保网络设备实际发送信号的天线端口和终端设备确定的天线端口相匹配，提升系统在部分通道关断下的系统性能。下面结合图3所示的流程详细描述。
步骤302中，第一映射关系可能存在多种实现方式。本申请实施例中，业务量在不同取值范围内，需要开启的射频通道的数量不同。不同取值范围中，取值范围越小，需要开启的射频通道的数量越少。
举例来说，假设网络设备包括的射频通道数量为N，N为大于0的偶数，第一映射关系可以如表1所示。
表1
Figure PCTCN2021075984-appb-000001
表1中，第一业务量阈值小于第二业务量阈值，第一业务量阈值和第二业务量阈值可以为网络设备配置的，也可以为通信标准中定义的，还可以通过其他方式确定，在此不再赘述。
当然，表1只是示例，第一映射关系还可能存在其他情况，具体可以以此类推，不再逐一举例说明。
再举例来说，假设网络设备有8个射频通道，以及配置有4个天线端口；业务量可以分为四挡，按照从小到大依次分别为第一业务量阈值，第二业务量阈值，第三业务量阈值和第四业务量阈值，对应开启的射频通道数量可以分别为1个射频通道，2个射频通道，4个射频通道和8个射频通道。
在实施例一中，确定第一数量的射频通道之后，还可以确定所述第一数量的射频通道与第二数量的天线端口的第二映射关系；其中，所述第二数量不随所述第一数量的变化而变化。例如第二数量可以为网络设备配置的天线端口数，可以是一个固定值。
确定第二映射关系之后，可以根据所述第二映射关系，通过所述第二数量的天线端口中每个天线端口映射的至少一个射频通道，传输每个天线端口对应的业务。
本申请实施例中，第二映射关系包括所述第二数量的天线端口中的任一所述天线端口与所述第一数量的射频通道中的至少一个射频通道之间的映射关系，在第二映射关系中，第二数量的天线端口中的每个天线端口映射至少一个射频通道，第一数量的射频通道中的每个射频通道映射至少一个天线端口。
一般地，不同的射频通道对应的传输信道不同，为了确保采用MIMO传输时，获得更好的分集增益或复用增益，需要确保不同天线端口之间对应的信道系数的相关性越小，其中不同信道系数之间的相关性的强弱表征信道系数之间的相似性，相关性越强，系数越相同，反之则系数越不同。因此，本申请实施例中，可以根据第一数量和第二数量确定第二映射关系，下面分不同情况讨论。
第一种情况，第一数量大于或等于第二数量。
在该情况下，第二数量的天线端口中不同的天线端口映射不同的射频通道。
其中，当两个天线端口映射的射频通道的数量不同时，可以认为这两个天线端口映射不同的射频通道；当两个天线端口映射的射频通道不是相同的射频通道时，也可以认为这两个天线端口映射不同的射频通道。
举例来说，假设网络设备需要开启4个射频通道，分别为RF1、RF2、RF3以及RF4，网络设备配置有4个天线端口，分别为R1、R2、R3以及R4。此时第二映射关系可以为R1映射RF1，R2映射RF2，R3映射RF3，R4映射RF4，具体的第二映射关系可以如图4以及表2所示。
表2
射频通道 RF1 RF2 RF3 RF4
天线端口 R1 R2 R3 R4
结合表2，在确定表2所示的第二映射关系之后，可以通过RF1传输R1对应的参考信号和数据信道；通过RF2传输R2对应的参考信号和数据信道；通过RF3传输R3对应的参考信号和数据信道；通过RF4传输R4对应的参考信号和数据信道。其它情况不再赘述。
第二种情况，第一数量小于第二数量。
在该情况下，第二数量的天线端口中不同的天线端口中至少有两个天线端口映射的射频通道相同。
进一步的，第一数量大于1，且所述第二数量的天线端口包括用于传输分集发送数据信道的至少两个天线端口时，所述至少两个天线端口中每个天线端口映射的射频通道不同。
其中，用于传输分集发送数据信道的至少两个天线端口，可以是指所述至少两个天线端口发送相同的数据流。
举例来说，假设网络设备包括4个射频通道，分别为RF1、RF2、RF3以及RF4，网络设备配置有4个天线端口，分别为R1、R2、R3以及R4，射频通道与天线端口的映射关系可以如表1所示。假设R1和R3发送相同的数据流，R2和R4发送相同的数据流，R1和R2发送不相同的数据流。这种场景下，R1和R3为用于传输分集发送数据信道的天线端口，R2和R4为用于传输分集发送数据信道的天线端口。
结合上面的例子，当确定只开启4个射频通道中的2个射频通道时，R1和R3需要映射不同的射频通道，R2和R4需要映射不同的射频通道。假设开启的射频通道为RF1和RF2，此时第二映射关系可以为R1映射RF1，R2映射RF1，R3映射RF2，R4映射RF2，具体的第二映射关系可以如图5以及表3所示。
表3
射频通道 RF1 RF1 RF2 RF2
天线端口 R1 R2 R3 R4
结合表3，在确定表3所示的第二映射关系之后，可以通过RF1传输R1对应的参考信号和数据信道，以及R2对应的参考信号和数据信道；通过RF2传输R3对应的参考信号和数据信道，以及R4对应的参考信号和数据信道。
当然，在上面的例子中，R1和R2也可以映射RF2，R3和R4也可以映射RF1。
可选地，第一种情况和第二种情况下，不同天线端口映射的射频通道不同还可以包括基于相同的一组射频通道和不同的组合系数构成；比如，编号为i(i＝1,2,3,4)端口R i与编号为j(j＝1,2,…,8)通道RF j之间的映射关系为R i＝∑ jα ijRF j，(j＝1,2,….,8)其中α ij为第j个通道与第i个端口之间的映射系数，一般为复数。该映射关系表示天线端口R i的部分数据经过映射系数α ij处理后由通道RF j发送。
进一步的，第二种情况中，当第一数量等于1时，第二数量的天线端口均与这一个射频通道映射。此时，使用相同的射频通道发送所有不同天线端口对应的参考信号和数据信道。
结合上面的例子，当确定只开启4个射频通道中的RF1时，R1、R2、R3以及R4均映射RF1，R3映射RF2，R4映射RF2，具体的第二映射关系可以如图6以及表4所示。
表4
射频通道 RF1 RF1 RF1 RF1
天线端口 R1 R2 R3 R4
结合表4，在确定表4所示的第二映射关系之后，可以通过RF1传输R1对应的参考信号和数据信道，R2对应的参考信号和数据信道，R3对应的参考信号和数据信道，以及R4对应的参考信号和数据信道。
进一步的，在实施例一中，为了确保射频通道关断前后的传输性能的不变，需要不改变用于测量覆盖的参考信号在单位资源上的功率，因此，用于发送一个天线端口对应的业务所对应的单位资源的总功率不变，且该总功率由该天线端口对应的多个射频通道的功率来提供。
举例来说，如表5(a)所示的8射频通道4天线端口(8T4P)的MIMO系统中，其中T表示通道，P表示天线端口；网络设备配置8个射频通道，配置的天线端口数为4。在8个射频通道全部开启的时候，每个射频通道在其映射的天线端口的单位资源上提供的功率为P 0，相应地，每个天线端口对应的参考信号在单位资源上的总功率为2P 0，其中一个天线端口由两个射频通道来提供功率。当关掉一半射频通道后变为4射频通道4天线端口(4T4P)，此时，每个天线端口映射一个射频通道，因此每个天线端口只有一个射频通道提供功率。为了保证每个天线端口对应的参考信号在单位资源上的总功率保持不变，每个射频通道给各自映射的天线端口所发送的参考信号的单位资源上提供的功率为2P 0，具体可以参考表格5(a)所示。
进一步地，当关掉3/4的射频通道变为2射频通道4天线端口(2T4P)时，此时，一个射频通道需要给对应的两个天线端口发送的业务提供功率，为了保证每个天线端口对应 的参考信号在单位资源上的总功率保持不变，且每个射频通道给各自映射的天线端口所发送的参考信号提供的功率为2P 0。进一步地，关掉7/8的射频通道变为1射频通道4天线端口(1T4P)时，此时，一个射频通道需要给对应的四个天线端口发送的参考信号提供功率，且每个射频通道给各自映射的天线端口所发送的参考信号提供的功率为2P 0，具体可以参考表格5(b)所示。
表5(a)

表5(b)
Figure PCTCN2021075984-appb-000003
通过上面的实施例，可以实现根据业务量确定开启的射频通道的数量，从而实现降低网络设备的功耗。进一步的，在只开启部分射频通道的情况下，仍可以支持MIMO传输模式，包括分集和空分复用，且保证小区覆盖性能不变，从而可以不降低业务传输性能。
而且在部分射频通道关断之后，网络设备的天线端口仍然基于映射的射频通道发送对应的业务，因此网络设备不需要通知终端设备关断了哪些天线端口的射频通道，从而不需要重配任何天线端口参数或传输模式。进一步的，由于网络设备关断部分射频通道之后，天线端口仍然可以发送业务，因此网络设备也不需要进行重新启动。
实施例二：
现有射频通道关断的技术一般都要求射频通道关断的同时，关断对应的天线端口，且保证关断参考信号和数据信道的天线端口的一致性。这类射频通道关断的方式一般需要基于天线端口的重配置或重新映射生效，使得生效时间长，不适用于通信忙时阶段。其中，“通信忙时”一般定义为一段时间内通信系数的平均资源利用率超过某个门限值，比如物理资源块利用率超过50％。
然而，即使在通信忙时，也存在单位时间资源上业务的波动，比如不同子帧(subframe)或传输时间间隔，在某些单位时间资源上出现轻载业务，从而使得这些单位时间内高阶的MIMO传输能力成为了冗余，因此，可以关断部分射频通道实现节能。
在这类场景下，参考信号对应的射频通道如果发生改变，但天线端口未变的情况下，终端设备的信道质量测量会下降，从而导致后续传输效率的下降，因此，本申请实施例提供一种参考信号和数据信道不对称的射频通道关断方法，可以避免对终端设备测量参考信号的影响，又能通过数据信道对应的射频通道关断实现节能。需要说明的是，在轻载业务 时，还可以通过其它补偿传输手段(例如自适应编码调制)，确保单位时间资源上的轻载业务实现准确传输，从而实现既确保了单位时间资源上的准确传输，又实现了通道关断下的节能。下面结合图3所示的流程详细描述。
在步骤301中，第一时间单元可以为以传输时间间隔(transmit time interval，TTI)或者时隙(slot)或者子帧(subframe)或者符号或者无线帧等为单位。
在实施例二中，可以将网络设备包括的射频通道划分为至少两个射频通道组。以下以划分为两个射频通道组为例进行说明，其他情况可以以此类推。
网络设备包括的射频通道划分为第一射频通道组和第二射频通道组时，所述第二射频通道组可以为第一射频通道组的子集。其中，所述第二射频通道组中包括的射频通道属于所述第一射频通道组和所述第二射频通道组共享的射频通道，且所述第一射频通道组中包括的射频通道的数量大于第二射频通道组包括的射频通道的数量。
可选的，第一射频通道组中的射频通道为网络设备包括的所有射频通道。
举例来说，网络设备包括8个射频通道，第一射频通道组可以为网络设备包括的所有8个射频通道，第二射频通道组包括的射频通道可以为8个射频通道中的任意4个射频通道。
本申请实施例中，为了保证业务的正常传输，不同业务量映射的开启的射频通道数量，即第一映射关系可以如表6所示。
表6
Figure PCTCN2021075984-appb-000004
结合表6，如果第一时间单元的业务量小于第一阈值，则在所述第一时间单元内开启所述第一射频通道组或者所述第二射频通道组；如果第一时间单元的业务量大于或等于第一阈值，则在所述第一时间单元内开启所述第二射频通道组。
其中，第一阈值的具体取值可以根据实际情况确定，本申请实施例对此并不限定。
进一步的，结合前面的描述，当在第一时间单元内，可以按照以下方法传输参考信号或者数据信道：
如果第一时间单元的业务量大于或等于所述第一阈值，则在所述第一时间单元内开启第一射频通道组，并通过所述第一射频通道组对应的第一天线端口组发送参考信号以及数据信道；
如果第一时间单元的业务量小于所述第一阈值，则在所述第一时间单元内需要发送参考信号时，开启第一射频通道组，并通过所述第一射频通道组对应的第一天线端口组发送所述参考信号；在所述第一时间单元内需要发送数据信道时，开启第二射频通道组，并通过所述第二射频通道组对应的第二天线端口组发送所述数据信道。
其中，第一天线端口组和第二天线端口组均包含至少一个天线端口。所述第二天线端口组为第一天线端口组的子集，即所述第二天线端口组中任一天线端口都属于第一天线端口组，且所述第一天线端口组中至少包含一个不属于第二天线端口组的天线端口。
举例来说，如图7所示，第一时间单元为一个包括14个正交频分复用(Orthogonal  Frequency Division Multiplexing，OFDM)符号的子帧，14个OFDM符号按照时间顺序分别为符号0至符号13。其中在符号0、符号4、符号7以及符号11中需要发送参考信号。
假设当前确定第一时间单元的业务量小于第一阈值，那么结合表6，可以确定需要开启第一射频通道组或第二射频通道组。假设第一射频通道组包括4个射频通道，分别为RF1、RF2、RF3以及RF4；第二射频通道组包括2个射频通道，分别为RF1以及RF2。为此，在第一时间单元的符号0、符号4、符号7以及符号11中，可以开启第一射频通道组，并通过第一射频通道组发送参考信号；在第一时间单元中除符号0、符号4、符号7以及符号11之外的符号中，可以只开启第二射频通道组，并通过第二射频通道组发送数据信道。另外，如果在参考信号所在的OFDM符号(符号0、符号4、符号7以及符号11)中，也有部分频域资源用于发送数据信道，则该部分频域资源上发送数据信道所用的射频通道与其它发送数据信道的OFDM符号所用的射频通道相同。
需要说明的是，在实施例二中，发送数据信道的射频通道数(或者天线端口数)与发送参考信号的射频通道数(或者天线端口数)的不同，可能会引起信道估计的不匹配，导致网络传输性能的下降。例如，一个基于配置为4天线端口和传输模式TM4的终端设备，还是基于4个天线端口做信道测量以及预编码矩阵索引反馈，且在接收数据信道时所用预编码的长度为4；而实际上，网络设备发送数据信道时所用的天线端口为2，因此发送侧的预编码长度为2。一般地，网络设备基于第一射频通道组对应的天线端口组发送参考信号，基于第二射频通道组对应的天线端口组发送数据信道，且基于第二射频通道组对应的天线端口数确定预编码长度来发送数据信道。
通过上面的过程可知，根据第一时间单元的业务量确定开启的射频通道，发送参考信号的射频通道数和发送数据信道的射频通道数不同，不论业务量是多少，发送参考信号的射频通道数始终保持不变，从而可以确保在关断部分射频通道时，满足当前第一时间单元内业务量的同时，又不影响参考信号的发送，不影响终端设备测量参考信号量，确保后续传输的高业务量需求。
实施例三：
随着无线通信网络业务多元化以及大容量的需求，基于多个小区间(可以是相同频点对应的多个小区或不同频点对应的多个小区)聚合大容量的传输成为了关键技术之一。为了实现网络侧的简易或低成本部署，基于多个小区对应的射频通道能够实现共享。然而，由于小区间业务量需求的差异，实际传输中不同小区对射频通道数或天线端口数的需求不同，这就使得共享的射频通道对于某些小区是冗余的，因此在传输过程中可以关断一部分小区的射频通道实现节能，下面结合图3所示的流程详细描述。
在实施例三中，网络设备可以通过载波聚合等方式同时设置多个小区，以下以包括第一小区和第二小区为例进行描述，其他情况可以以此类推。
需要说明的是，本申请实施例对第一小区和第二小区并不限定，举例来说，第一小区可以为LTE小区，第二小区可以为NB-IOT小区。
当第一小区和第二小区属于同一个网络设备时，在步骤301中，确定的第一时间单元的业务量可以包括第一小区的第一业务量和第二小区的第二业务量。
在实施例三中，可以将网络设备包括的射频通道划分为至少两个射频通道组。以下以划分为两个射频通道组为例进行说明，其他情况可以以此类推。
网络设备包括的射频通道可以划分为第三射频通道组和第四射频通道组时，所述第四二射频通道组可以为第三射频通道组的子集。其中，所述第四射频通道组中包括的射频通道属于所述第三射频通道组和所述第四射频通道组共享的射频通道，且所述第三射频通道组中包括的射频通道的数量大于第四射频通道组包括的射频通道的数量。
可选的，第三射频通道组中的射频通道为网络设备包括的所有射频通道。
举例来说，网络设备包括4个射频通道，第三射频通道组可以为网络设备包括的所有4个射频通道，第四射频通道组包括的射频通道可以为4个射频通道中的任意2个射频通道。
