Definitions

  • Binary phase shift keying is a method that uses complex wave combinations that deviate from the phase to express information keying and phase shifting. It can convert analog signals into data values and is widely used in medium and high-speed data transmission. Scenes. However, in fading channel and circuit switch data (CSD) scenarios, since the low-order modulation and coding scheme (MCS) usually works under low signal-to-noise ratio (signal noise ratio, SNR) conditions, especially MCS 0 usually corresponds to the scene with the lowest signal-to-noise ratio. At this time, in order to improve the link quality, it is usually sent as a single stream to improve the strength of the received signal. In this case, the diversity effect of the signal in the two dimensions of in-phase (I) and quadrature (Q) cannot be fully utilized, which may lead to decoding failure when fading is severe.

Description

二进制移相键控(binary phase shift keying，BPSK)是利用偏离相位的复数波浪组合来表现信息键控移相方式的一种，可以将模拟信号转换成数据值，广泛应用于中、高速数据传输场景。但是在衰落信道和电路交换数据业务(circuit switch data，CSD)场景中，由于低阶调制编码策略(modulation and codingscheme，MCS)通常工作在低信噪比(signal noise ratio，SNR)条件下，特别是MCS 0通常是对应信噪比最低的场景，这时，为了提升链路质量，通常按照单流进行发送，以提升接收信号的强度。在此种情形下，无法充分利用信号在同相(in-phase，I)/正交(quadrature，Q)两个维度的分集效应，在衰落严重时会导致译码失败的问题。

应理解，本申请实施例中，终端设备可以是用于实现终端设备功能的装置，也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端中。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。
本申请实施例中的网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、 基带单元(base band 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，还可以为第五代(5th generation，5G)，如，新一代无线通信系统(new radio，NR)中的下一代基站(next generation node B，gNB)，或，传输点(TRP或TP)，5G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，还可以为构成gNB或传输点的网络节点，如基带单元(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。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。gNB还可以包括有源天线单元(active antenna unit，简称AAU)。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。由于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，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
应理解，本申请实施例中，网络设备可以是用于实现网络设备功能的装置，也可以是能够支持网络设备实现该功能的装置，例如芯片系统，该装置可以被安装在网络设备中。
本申请实施例的技术方案可以应用于NR通信系统中的反向散射通信、无源物联通信等业务场景以及各种通信系统，例如：LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、5G系统、车到其它设备(vehicle-to-X，V2X)，其中V2X可以包括车到互联网(vehicle to network，V2N)、车到车(vehicle to vehicle，V2V)、车到基础设施(vehicle to infrastructure，V2I)、车到行人(vehicle to pedestrian，V2P)等、车间通信长期演进技术(long term evolution-vehicle，LTE-V)、车联网、机器类通信(machine type communication，MTC)、物联网(Internet of things，IoT)、机器间通信长期演进技术(long term evolution-machine，LTE-M)，机器到机器(machine to machine，M2M)，设备到设备(device to device，D2D)等或未来演进的通信系统，例如第六代(6th generation，6G)系统。
当前，802.11调制格式支持二进制相移键控(binary phase shift keying，BPSK)/正交相移键控(quadrature phase shift keying，QPSK)/16正交振幅调制(quadrature amplitude modulation，QAM)/…/4096正交振幅调制(quadrature amplitude modulation，QAM),其中低阶(BPSK，可叠加DCM技术)调制主要用作远覆盖、干扰场景使用。在衰落信道条件下BPSK并没有充分利用I/Q两路信号的分集收益。如图2所示在衰落信道下部分子载波，部分子载波信噪比(signal noise ratio，SNR)大于解码需要的SNR，导致信号功率浪费；部分子载波SNR小于解码需要的SNR，当这种深衰子载波占比较大时会导致解码失败，性能退化。
如下表1和表2所示，当前802.11b/a/n/ac/ax/be中MCS 0均为BPSK调制。
表1当前802.11部分协议中MCS 0指示BPSK调制的情形
表2当前802.11部分协议中MCS 0指示BPSK调制的情形

在衰落信道和CSD场景中，由于MCS通常工作在低SNR条件下，特别是MCS 0通常是对应信噪比最低的场景，这时，为了提升链路质量，通常按照单流进行发送，以提升接收信号的强度。在此种情形下，无法充分利用信号在I/Q两个维度的分集效应，在衰落严重时会导致译码失败的问题。
基于此，本申请提出了一种信道编码的方法，以期望能够降低信道编码功耗和复杂度的同时，又能保证一定的信道编码性能。
下面以第一通信装置和第二通信装置的之间的交互为例，对本申请的技术方案进行详细描述。其中，第一通信装置可以是图1中的终端设备(例如终端设备102、终端设备103或终端设备104)，第二通信装置可以是图1中的网络设备101；可选地，第一通信装置和第二通信装置还可以均为终端设备，此时该通信系统支持sidelink通信技术，例如第一通信装置是终端设备102和第二通信装置是终端设备103或终端设备104，或者第一通信装置是终端设备103和第二通信装置是终端设备104或终端设备102等。
图3示出了本申请调制编码方法的一例示意性流程图。
S310，第一通信装置根据第一调制方式对第一比特信息进行调制编码，得到第二比特信息，第一调制方式包括将第一比特信息在频域上进行映射，得到第三比特信息，将第三比特信息与第一比特信息组成比特对，对比特对进行QPSK调制编码得到第二比特信息。
其中，映射包括但不限于循环移位或者其他典型的映射方式，例如一对一映射、一对多映射、多对一映射等。
其中，将第一比特信息在频域上进行映射，具体可以包括：根据第一通信装置发送所述第二比特信息的发送模式，将第一比特信息在频域上进行循环移位。
可选的，第一比特信息包括M个比特信息，M为正整数。作为第一种可能的实现方式，将第一比特信息在频域上进行循环位移具体可以包括：将M个比特信息按照连续的方式在频域上进行循环移位。例如，图4所示，在一个正交频分复用(orthogonal frequency divisition multiplexing，OFDM)符号内的一个用户的资源单元(resource unit，RU)内，相对于传统的BPSK调制，本申请所提供的第一调制方式将该用户的所有比特信息在频域上进行循环移位，即在一个比特序列中，b(0)、b(1)、b(2)等相邻，b(n)、b(n+1)、b(n+2)等相邻，每个子载波上循环移位后的比特同原始比特合并进行QPSK调制。作为第二种可能的实现方式，将第一比特信息在频域上进行循环位移具体可以包括：将M个比特信息按照间隔N个比特信息的方式在频域上进行循环位移，N为小于M的正整数。例如，如图5所示，在一个OFDM符号内的一个用户的RU内，相对于传统的BPSK调制，本申请所提供的第一调制方式将该用户的比特信息按照间隔1个比特信息在频域上进行循环移位，即在一个比特序列中，b(0)、b(2)、b(4)等相邻，b(1)、b(3)、b(5)等相邻，每个子载波上循环移位后的比特同原始比特合并进行QPSK调制。这样做，针对于在CSD场景下，频域衰落成周期的特点，可以降低邻近的比特信息均落入深衰子载波，提升调制编码的性能。
应理解，上述间隔1个比特信息只是一种可能的示例，在实际应用中可以根据不同的资源配置情况，间隔不同个数的比特信息，包括但不限于间隔1个比特信息、间隔2个比特信息等等。
S320，第一通信装置发送第二比特信息。
对应的，第二通信装置接收第二比特信息，并根据第一调制方式对第二比特信息进行解调处理，得到第一比特信息。
如图6所示，在本申请所提供的调制编码的方法中，在常规的信道编码、交织/低密度奇偶校验码(low density parity check code，LDPC)子载波映射之后，发送端设备(即第一通信装置)只需要在调制编码(modulation)时将对应用户的比特信息在频域上进行映射，然后与原始比特信息组成比特对，调用QPSK调制，随后施加常规的反向快速傅里叶变换(inverse fast fourier transform，IFFT)以及其他发送配置即可。接收端设备(即第二通信装置)只需要在常规的接收解码过程中新增按照QPSK进行多输入多输出(multiple input multiple output，MIMO)解调，且在对数似然比(log likelihood ratio，LLR)(可称为软信息比特)之后反向操作(demap)，对LLR软信息进行合并即可。
可选的，第一通信装置还可以发送指示信息，指示信息用于指示第一调制方式。对应的，第二通信装置接收指示信息，并根据指示信息获取第一调制方式。其中，指示信息可以是一个字段或者信令， 第一通信装置通过该字段或者信令向第二通信装置指示第一调制方式。
其中，在通过指示信息指示第一调制方式之前，第一通信装置和第二通信装置需要首先交互能力信息，确认均支持增强的调制编码策略(包括第一调制方式)。具体的，第一通信装置可以通过关联请求帧(Association Request frame format)或重关联请求帧(Association Request frame format)中的“Extended Capabilities”(拓展能力)进行增强调制编码能力指示。其中，Extend Capabilities element(元素)中有的Reserved bit(保留比特)可以扩展为增强调制编码能力指示。例如，Extend Capabilities element携带有关第一通信装置的能力的信息，具体的可如下表3或表4通过能力信息字段(Extend Capabilities)指示指定的能力，其中，“Octets”表示因特网标准使用的八位组，“Element ID”用于表示该元素的ID，“Length”用于表示长度，“Extend Capabilities”可以用于指示第一发送装置的指定的能力(例如，增强的调制编码策略，包括第一调制方式)，“The Extended Capabilities element is present if any of the fields inthis element are nonzero”即如果该元素中的任何字段为非零，则存在扩展功能元素。又例如，还可以如表5所示，该表格中存在“Reserved bit”(保留比特)，因此可通过“Reserved bit”指示指定的能力(例如，增强的调制编码策略，包括第一调制方式)。
表3第一通信装置能力信息可能的指示方式
表4第一通信装置能力信息可能的指示方式
表5第一通信装置能力信息可能的指示方式
应理解，上述以第一通信装置为例，对第一通信装置能力信息可能的指示方式进行了介绍。对应的，第二通信装置也可以通过相同的方式，对第二通信装置的能力信息进行指示。
在第一通信装置和第二通信装置交换能力信息均指示支持增强的调制编码策略(包括第一调制方式)后，可在接下来的信息传输中进行对应调制编码方式的发送和接收。其中，第一通信装置向第二通信装置指示第一调制方式可以由如下三种方式：
方式1：将U-SIG的字段进行拓展，用于指示第一调制方式。具体的，如下表6和表7所示，通过U-SIG中的Disregard bit(忽视比特)或Validate bit(检验比特)，例如U-SIG1中的B20-B24、B25；U-SIG2中的B2、B8)指示第一调制方式。在该方式中，对以太网(ethernet，ETH)帧进行统一指示，不区分用户，当该bit为0(或1)时，指示当MCS为MCS 0(或MCS 1)时为第一调制方式。
表6通过B20-B24、B25指示第一调制方式
表7通过B2、B8指示第一调制方式
方式2：将EHT-SIG的字段进行拓展，用于指示第一调制方式。具体的，如下表8和表9中所示，通过EHT-SIG中common field中的Disregard bit，例如B13-B16指示第一调制方式。在该方式中，对以太网(ethernet，ETH)帧进行统一指示，不区分用户，当该bit为0(或1)时，指示当MCS为MCS0(或MCS 1)时为第一调制方式。
表8通过B13-B16指示第一调制方式的示例1
表9通过B13-B16指示第一调制方式的示例2
方式3：将EHT-SIG的字段进行拓展，用于指示第一调制方式。具体的，如下表10中所示，通过EHT-SIG中User field中的Reserved bit(保留比特)进行指示，例如B15指示第一调制方式，该方案区分用户，只支持非多用户多输入多输出(non multi-user multiple-input multiple-output，non-MU-MIMO)，当该bit为0(或1)时，指示当MCS为MCS 0(或MCS 1)时为第一调制方式。
表10通过B15指示第一调制方式
应理解，上述列举的几种指示方式仅作为示例，不应作为对本申请技术方案的限定，本领域人员可知，通过其他信令或字段的方式均可以指示第一调制方式。
还应理解，上述图4和图5所示的两种可能的循环移位方式对应不同的第一调制方式，在进行指示时，可以采用不同的指示方式加以区分，例如，在表6所示的指示方式中，可以通过MCS 20(通过B20拓展得到)指示图4所示的第一调制方式，通过MCS 25(通过B25拓展得到)指示图5所示的第一调制方式；又例如，在表7所示的指示方式中，可以通过MCS 2(通过B2拓展得到)指示图4所示的第一调制方式，通过MCS 8(通过B8拓展得到)指示图5所示的第一调制方式。
根据本申请的技术方案，将用户的比特信息在频域上进行映射后，与原始比特信息组成比特对，调用正交相移键控调制，有助于在不增加额外资源的同时，提升调制编码的性能。本申请的技术方案，能够提升WIFI产品覆盖能力和低信噪比下的吞吐量(CSD和衰落信道场景约有2dB的增益)，方案简单，基本不需要增加资源。
