Specifically, multiple time slots of equal length that occupy the same time domain resources as the uplink time slots of frequency 1 are set to an idle state to ensure that normal communication between the two frequencies is not interfered with.
  • Frequency 2 only has an uplink time slot or is in an idle state, therefore no transmitting channel is needed. Switching between frequency 1 and frequency 2 can be achieved on demand simply by adjusting the frequency selection switch of receiving channel 1 in Figure 6.

This ensures that the uplink time slots of the two frequencies in the first communication device are staggered in the time domain resources, preventing overlap or coexistence of the two uplink time slots. According to this target transceiver mode, a receiving channel in the first communication device can receive data carried by the uplink time slots of these two frequencies in different time units.

Description

一种数据处理方法及相应装置
本申请要求于2024年07月10日提交国家知识产权局、申请号为202410925130.X、申请名称为“一种数据处理方法及相应装置”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
本申请涉及通信技术领域，具体涉及一种数据处理方法及相应装置。
背景技术
随着无线通信领域对频谱资源的需求日益增加，更多频率用于无线通信，例如U6G、厘米波、毫米波等频率。为此，单个有源天线单元(active antenna unit，AAU)或者射频拉远单元(remote radio unit，RRU)系统需要集成更多频段，每个频率都有其独有的射频通道资源，构成了多频率的通信系统。
然而，当系统以时分双工(time division duplex，TDD)的模式运行时，系统在不同时隙中处理数据的接收和发送。具体的，当频率处于下行时隙时，系统的接收通道处于空闲状态，而当频率切换到上行时隙时，系统的发送通道处于空闲状态。因此，如何提高多频率的TDD系统中射频通道的利用率成了亟待解决的问题。
发明内容
本申请实施例提供了一种数据处理方法及相应装置，用于在多频TDD系统中，实现射频通道的复用，提高射频通道的利用率，降低射频通道硬件资源的需求。本申请还提供了相应装置、计算机可读存储介质和计算机程序产品等。
第一方面，本申请实施例提供了一种数据处理方法，该方法应用于多个频率的时分双工TDD系统中，该方法包括：
第一通信装置根据多个频率中每个频率的时隙配比关系确定目标收发模式，该第一通信装置包括多个射频通道，目标收发模式用于指示多个射频通道在多个时间单元中的开关状态；其中，第一射频通道用于传输至少两个频率的数据，第一射频通道为多个射频通道中的一个射频通道，该至少两个频率为多个频率中的频率；
第一通信装置根据该目标收发模式接收数据或发送数据。
本申请中，第一通信装置可以是接入网设备、终端设备或者接入网设备中的芯片、终端设备中的芯片。
TDD是一种通信系统的双工方式，它使用同一频率信道的不同时隙，用时间来分离接收与传送信道(或上下行链路)。上行传输(信号从终端设备发送到接入网设备)和下行传输(信号从接入设备发送到终端设备)被分配到不同的时隙中，频率的时隙配比关系即指示频率的用于上行传输的时隙与用于下行传输的时隙之间的比值。总的来说，目标收发模式是一种指示机制，按照预定时域资源的时间顺序，指导第一通信装置内的射频通道执行相应的接收与发送操作。
需要说明的是，在面对不同的通信场景，TDD系统中频率的时隙配比关系并不相同。例如在流媒体服务、文件下载等下行传输需求较多的场景中，时隙配比关系中的下行时隙占比通常较高，通常下行时隙与上行时隙之间的比值为“4:1”，即5个连续的时隙中，有4个用于下行数据传输，1个用于上行数据传输；或者比值为“8:2”或者“7:3”等，具体不做限定。
本申请中的目标收发模式既是将多个频率的上行时隙(或下行时隙)在时域资源中进行相互错开。采用上述方案，上行链路(或下行链路)在任意一个时间点中只需一个接收通道(或发送通道)即可执行信号的接收(或信号的发送)，从而实现多个频率之间射频通道的分时复用，降低射频通道硬件资源的需求，降低系统的硬件复杂度。
在一种可能的实现方式中，多个射频通道的类型包括接收通道和发送通道，目标频率的第一时隙配比关系为第一时隙与第二时隙之间的比值；其中，接收通道用于在第一时隙中接收目标频率传输的数据，发送通道用于在第二时隙中发送目标频率传输的数据，目标频率为多个频率中的一个频率。
在一种可能的实现方式中，若第一射频通道为接收通道，目标收发模式包括第一分配结果，第一分配结果用于指示第一射频通道在第一时间单元中接收第一数据，以及在第二时间单元中接收第二数据，第一数据和第二数据属于至少两个频率中不同频率中的数据，第一时间单元和第二时间单元为不同的时间单元。
在一种可能的实现方式中，若第一射频通道为发送通道，目标收发模式包括第二分配结果，第二分配结果用于指示第一射频通道在第三时间单元中发送第三数据，以及在第四时间单元中发送第四数据，第三数据和第四数据属于至少两个频率中不同频率中的数据，第三时间单元和第四时间单元为不同的时间单元。
在一种可能的实现方式中，至少两个频率包括第一频率和第二频率，第一频率的起始子帧与第二频率的起始子帧不在同一个时间单元中。
本申请中，通过调整频率的起始时间点，即调整起始子帧对应的时间单元，实现至少两个频率之间的上行时隙(或下行时隙)相互错开。
在一种可能的实现方式中，至少两个频率之间的子载波间隔不同。
在一种可能的实现方式中，至少两个频率包括辅助上行SUL频率。
本申请中，SUL频率为仅有上行时隙的频率，可以通过将部分时隙状态调整为空闲状态(Idle)来实现至少两个频率之间的上行时隙相互错开。
第二方面，本申请实施例提供了一种数据处理装置，该装置应用于多个频率的时分双工TDD系统中，该装置为第一通信装置。该装置包括：
处理模块，用于根据多个频率中每个频率的时隙配比关系确定目标收发模式，第一通信装置包括多个射频通道，目标收发模式用于指示多个射频通道在多个时间单元中的开关状态；其中，第一射频通道用于传输至少两个频率的数据，第一射频通道为多个射频通道中的一个射频通道，至少两个频率为多个频率中的频率；
收发模块，用于根据目标收发模式接收数据或发送数据。
在一种可能的实现方式中，多个射频通道的类型包括接收通道和发送通道，目标频率的第一时隙配比关系为第一时隙与第二时隙之间的比值；其中，接收通道用于在第一时隙中接收目标频率传输的数据，发送通道用于在第二时隙中发送目标频率传输的数据，目标频率为多个频率中的一个频率。
在一种可能的实现方式中，若第一射频通道为接收通道，目标收发模式包括第一分配结果，第一分配结果用于指示第一射频通道在第一时间单元中接收第一数据，以及在第二时间单元中接收第二数据，第一数据和第二数据属于至少两个频率中不同频率中的数据，第一时间单元和第二时间单元为不同的时间单元。
在一种可能的实现方式中，若第一射频通道为发送通道，目标收发模式包括第二分配结果，第二分配结果用于指示第一射频通道在第三时间单元中发送第三数据，以及在第四时间单元中发送第四数据，第三数据和第四数据属于至少两个频率中不同频率中的数据，第三时间单元和第四时间单元为不同的时间单元。
在一种可能的实现方式中，至少两个频率包括第一频率和第二频率，第一频率的起始子帧与第二频率的起始子帧不在同一个时间单元中。
在一种可能的实现方式中，至少两个频率之间的子载波间隔不同。
在一种可能的实现方式中，至少两个频率包括辅助上行SUL频率。

下面对本申请的终端设备和接入网设备进行介绍。
终端设备可以是能够接收接入网设备调度和指示信息的无线终端设备。无线终端设备可以是指向用户提供语音和/或数据连通性的设备，或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备或具有感知功能的设备。
终端设备，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是包括无线通信功能和/或感知功能(向用户提供语音或数据连通性)的设备，例如，具有无线连接功能的手持式设备、或车载设备等。目前，一些终端设备的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、无人机、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、车联网中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、或智慧家庭(smart home)中的无线终端等。例如，车联网中的无线终端可以为车载设备、整车设备、车载模块、车辆等。工业控制中的无线终端可以为摄像头、机器人等。智慧家庭中的无线终端可以为电视、空调、扫地机、音箱、机顶盒等。
接入网设备是部署在无线接入网中为终端设备提供无线通信功能和/或感知功能的设备。例如，接入网设备可以为将终端设备接入到无线网络的无线接入网(radio access network，RAN)节点。接入网设备也可以是部署在无线接入网中能够与其它接入网设备通信，可以为接入网设备间提供无线通信功能和/或感知功能的设备。
接入网设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G移动通信系统中的接入网设备。例如，新空口(new radio，NR)系统中的下一代基站(next generation NodeB，gNB)，传输接收点(transmission reception point，TRP)，传输点(transmission point，TP)；或者，5G移动通信系统中的基站的一个或一组(包括多个天线面板)天线面板；或者，接入网设备还可以为构成gNB或传输点的网络节点。例如，基带单元(baseband unit，BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来。因此在该架构下，高层信令(如RRC层信令)也可以认为是由DU发送的，或者，由DU和AAU发送的。可以理解的是，接入网设备可以为包括CU节点、DU节点、AAU节点中一个或多个的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的接入网设备，也可以将CU划分为核心网(core network，CN)中的接入网设备，本申请对此不做限定。
为便于理解，下面对本申请实施例涉及到的技术术语做简单介绍：
(1)射频通道：射频通道通过馈电网络与通信装置的天线阵列相连，通常由一系列的信号分配器、混频器、功率放大器(power amplifier，PA)和低噪声放大器(low noise amplifier，LNA)组成，射频通道资源包含：数模转换(digital to analog conversion，DAC)、模数转换(analog to digital conversion，ADC)、数字中频处理模块、基带处理模块等。其中射频通道的类型包括发送通道，对基带信号进行上变频到射频信号并通过天线发送到空间中；和接收通道，利用天线接收到的射频信号进行下变频到基带信号，进行数字端的处理。
(2)子载波间隔(subcarrier spacing，SCS)：子载波的宽度，在OFDM系统中，将一定带宽的载波进行分割得到子载波，子载波为用于传输信号的无线电波。子载波间隔通常为15千赫兹(kHz)，或者15kHz的倍数，例如30kHz、60kHz、120kHz等。其中，根据第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)协议规定，不同波长的电磁波对应的子载波间隔不同。
(3)时工双分(time division duplex，TDD)的时隙配比关系：
TDD是一种通信系统的双工方式，它使用同一频率信道(即载波)的不同时隙，用时间来分离接收与传送信道(或上下行链路)。具体来说，上行链路(终端设备向网络设备发射)和下行链路(网络设备向终端设备发射)的信息传输是在同一载波上通过时分实现的。
在TDD系统中，时隙是TDD系统中进行数据传输的基本时间单位。上行传输和下行传输被分配到不同的时隙中，确保在同一频率上不会发生上行和下行信号的冲突。为了应对不同的业务需求，通常通过调整时隙配比关系来调整系统中上行时隙与下行时隙的比例。具体的，面对下行传输需求较多的场景，增加下行时隙的占比；同理，在面对上行传输需求较多的场景，增加上行时隙的占比。
其中，频率对应的子载波间隔的大小直接影响到时隙的长度。具体来说，较小的子载波间隔会导致较长的符号长度，进而可能增加时隙的长度。相反，较大的子载波间隔会导致较短的符号长度，从而可能减少时隙的长度。
具体的，当子载波间隔为30kHz时，符号长度为1/30kHz，此时一个时隙的长度为0.5ms。当子载波间隔进一步增大到120kHz时，每个时隙的长度会缩短到0.125ms，是30kHz时的1/4。
如图2所示，图2为多频率TDD时隙配比示意图。多频率系统包括频率1和频率2，频率1和频率2的下行时隙与上行时隙的时隙配比关系都是4:1。即5个连续的时隙中，有4个用于下行数据传输，1个用于上行数据传输。其中D代表downlink为下行时隙，S代表TDD switch为切换时隙，U代表uplink为上行时隙。多频率系统在频率处于下行时隙时，上行资源空闲，反之当频率处于上行时隙时，下行资源空闲。
需要说明的是，每个时隙包括多个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。在S时隙中的OFDM符号，按照作用类型可以分成属于下行链路的下行符号、暂停工作的保护间隔符号和属于上行链路的上行符号构成，用于连接D时隙与U时隙，保护间隔符号是为了确保上下行转换时信号互不干扰而设置的一段时间间隔。S时隙不完全等同于一个完整的上行时隙或下行时隙，但可以看作是一个下行时隙。
对应的，针对于多频段多通道AAU或者RRU系统，各自频段拥有各自独立的通道资源。如图2中的第一通信装置，当频率1处于下行时隙时，利用发送通道1来执行信号的发送，即频率1的混频器连接TDD切换开关中上面的通道；当频率1处于上行时隙时，则利用接收通道1进行信号的接收，即频率1的混频器连接TDD切换开关中下面的通道。类似地，频率2的发送和接收操作则分别由发送通道2和接收通道2独立处理。然而申请人研究发现，多频系统通道各自独立的方案在实际的上下行分时复用过程中，造成了明显的通道资源未充分利用现象，进而导致了资源浪费的问题。
以上介绍了本申请方案的应用场景，下面结合第一通信装置介绍本申请实施例提供了一种数据处理方法，该方法应用于拥有多个频率的TDD系统中。
本申请中，第一通信装置可以是接入网设备、终端设备或者接入网设备中的芯片、终端设备中的芯片。第一通信装置中集成了多个不同频率的基带资源。接下来，以第一通信装置为接入网设备，且能够同时使用两个频率为例，介绍本申请实施例提供的数据处理方法。其中，这两个频率分别为标识为“频率1”和“频率2”。
如图3所示，本申请实施例提供的数据处理方法包括：
301.第一通信装置根据多个频率中每个频率的时隙配比关系确定目标收发模式。
本申请中，第一通信装置包括多个射频通道，所述目标收发模式用于指示所述多个射频通道在多个时间单元中的开关状态；其中，第一射频通道用于传输该两个频率的数据，所述第一射频通道为所述多个射频通道中的一个射频通道。总的来说，目标收发模式是一种指示机制，按照预定时域资源的时间顺序，指导第一通信装置内的射频通道执行相应的接收与发送操作。
具体的，在面对不同的通信场景，TDD系统中频率的时隙配比关系并不相同。例如在流媒体服务、文件下载等下行传输需求较多的场景中，时隙配比关系中的下行时隙占比通常较高，通常下行时隙与上行时隙之间的比值为“4:1”，“8:2”或者“7:3”等。
本申请中，有2种确定前述的目标收发模式的实施方式，以下进行详细介绍：
(1)调整频率的起始时间点。
示例性的，以通信场景为下行传输需求较多的场景为例，频率1和频率2的下行时隙与上行时隙的时隙配比关系都是4:1，且频率1和频率2的子载波间隔相同，都为30kHz。
请参阅图4，图4为子载波间隔相同的多频TDD系统上行时隙错开示意图。具体的，将频率2的起始时间点延后一个时隙时长。可选的，针对两个频率的下行时隙与上行时隙的时隙配比关系都是4:1的情况，还可以选择将频率2的起始时间点延后两个时隙时长或三个时隙时长，具体此处不做限定。
对应的，由图4可以看出，在相同的时域资源内，频率1和频率2存在同时处于下行时隙的情况。因此，第一通信装置为了确保信号的顺利发送，为频率1和频率2分别配置了独立的发送通道，分别为发送通道1和发送通道2。而由于频率1和频率2之间的上行时隙是相互错开的，仅需通过调整图4中接收通道1的频率选择开关，即可实现频率1和频率2的按需切换。
具体的，当频率1为上行时隙时(图4上图中频率1的U)，接收通道1将通过频率选择开关与频率1的混频器建立连接，以确保频率1的上行信号能够正确接收。随后，当频率2为上行时隙时(图4下图中频率2的U)，调整接收通道1的频率选择开关，使其与频率2的混频器相连，从而确保频率2的上行信号也能被有效接收。
进一步的，当第一通信装置中还配置了时隙配比关系为4:1的频率3时，同样可以通过调整频率3的起始时间点，使得频率3的上行时隙与频率1和频率2的上行时隙相互错开，从而实现接收通道对3个频率的复用。
示例性的，同样以下行传输需求较多的场景为例，当频率1为SUB6GHz频率、频率2为毫米波频率时，根据3GPP协议规定，这两种频率信号的子载波间隔不同。
如图5所示，图5为子载波间隔相同的多频TDD系统上行时隙错开示意图。其中，频率1的下行时隙与上行时隙的时隙配比关系是4:1，而频率2的下行时隙与上行时隙的时隙配比关系是8:2。频率1的子载波间隔为30kHz，频率2的子载波间隔为120kHz。对应的，频率1与频率2的单个时隙长度不一致，30k子载波间隔的时隙长度较120k子载波间隔的时隙长度大4倍。
具体的，将频率2的起始时间点延后三个时隙时长(频率2的时隙长度)。可选的，还可以选择将频率2的起始时间点延后四个时隙时长或五个时隙时长，具体此处不做限定。
对应的，由图5可以看出，在相同的时域资源内，频率1和频率2存在同时处于下行时隙的情况。因此，第一通信装置为了确保信号的顺利发送，为频率1和频率2分别配置了独立的发送通道，分别为发送通道1和发送通道2。对于频率2的毫米波发送通道，由于采用混合波束成型(hybrid beamforming，HBF)架构，往往具有较少的通道，通过图5中的“功分网络”实现一个发送通道到多个频率2混频器的一对多连接。同样的，由于频率1和频率2之间的上行时隙是相互错开的，仅需通过调整图5中接收通道1的频率选择开关，即可实现频率1和频率2的按需切换。
(2)将频率的部分时隙状态调整为空闲状态。
如图6所示，图6为另一种通道复用场景，频率1为TDD频率，该频率可以从3GPP定义的所有TDD频率中任意选择，以下行时隙与上行时隙的时隙配比关系为4:1的30kHz频率为例。频率2为辅助上行(supplementary uplink，SUL)频率(频率中仅存在U)，同样，它也可以从3GPP定义的SUL频率范围内自由选取。
具体的，将SUL频率中与频率1的上行时隙处于相同时域资源的时隙，调整为空闲状态(Idle)，以确保两个频率间的正常通信不会受到干扰。若频率1和频率2的子载波间隔存在差异的情况下，需要对频率2中的特定时隙进行调整。具体来说，将那些与频率1上行时隙在相同时间范围内占据相同时域资源的、长度相等的多个时隙，设置为空闲状态，以确保两个频率间的正常通信不会受到干扰。
对应的，根据图6中第一通信装置的电路方案，实现该场景下的收通道复用。其中，频率2仅存在上行时隙或空闲状态，因此无需发送通道，仅需通过调整图6中接收通道1的频率选择开关，即可实现频率1和频率2的按需切换。
302.第一通信装置根据目标收发模式接收数据或发送数据。
具体的，目标收发模式如前述的图4至图6中所示，通过调整频率的起始时间点和/或将频率的部分时隙状态调整为空闲状态，使得第一通信装置中的两个频率的上行时隙能够在时域资源中相互错开，不会出现两个上行时隙重叠或并存的情况。根据该目标收发模式，第一通信装置中的一个接收通道能够在不同时间单元中接收这两个频率的上行时隙所携带的数据。
对应的，当第一通信装置为终端设备时，根据该目标收发模式，终端设备中的一个发送通道能够在不同时间单元中发送这两个频率的上行时隙所携带的数据。
应理解，以上例子属于下行传输需求较多的场景，两个频率中的上行时隙占比较少，所以能实现两个频率的上行时隙在时域资源中相互错开，接收通道进行复用。对应的，在上行传输需求较多的场景中，两个频率中的下行时隙占比较少。同样也能够实现两个频率的下行时隙在时域资源中相互错开，发送通道进行复用。
本申请中，通过对各自频率的TDD系统帧结构做定时调整，包括调整频率的起始时间点以及将部分时隙状态调整为空闲状态。使得多个频率中占比较少的上行时隙(或下行时隙)相互错开，使得上行链路(或下行链路)在任意一个时间点中只需一个接收通道(或发送通道)即可执行信号的接收(或信号的发送)。从而根据本申请实施例提供的通道复用电路方案，实现多个频率之间射频通道的分时复用，降低射频通道硬件资源的需求，降低系统的硬件复杂度。
特殊的，还存在接收通道和发送通道均可实现复用的情况。上行时隙与下行时隙的比值都是1:1，又或者两个频率的上行时隙与下行时隙的比值刚好相反，例如频率1的是4:1，频率2的是1:4。通信装置中的接收通道和发送通道都能进行复用。
接下来以两个频率的上行时隙与下行时隙的比值都是1:1为例。如图7所示，将频率2的起始时间点延后一个时隙时长，使得在任意的时域资源内，频率1和频率2之间的上行时隙以及下行时隙都能有效地错开。通过调整图7中频率选择开关和TDD切换开关实现频率1、频率2各自的收发状态切换。
具体的，当发送通道1发送频率1的D时隙，接收通道1接收频率2的U时隙，通过开关网络(频率选择开关、TDD切换开关)实现发送通道1、接收通道1与对应频率的混频器连接；反之，当发送通道1发送频率2的D时隙，接收通道1接收频率1的U时隙，通过开关网络实现发送通道1、接收通道1与对应频率的混频器连接，实现了一份收发通道资源在两个频段之间共享。
