  • UE A sends multi-port MP-RS, different ports of MP-RS use different sequences or different cyclic shifts, MP-RS can cover all working bandwidth, UB After B receives the multi-port MP-RS, it can obtain channel state information of different ports on the entire working bandwidth.
  • the MP-RS used in the "multi-port channel state information measurement” method multiplexes the MP-RS signal for multi-port channel state information measurement, and can obtain the channel state information of different ports of the current Sidelink unicast communication, saving
  • the channel state information-reference signal CSI-RS signaling overhead is improved, and resource utilization efficiency is improved.
  • MP-RS is used for "multi-port channel estimation”: UE A on the transmitting side can send MP-RS before PSCCH or PSSCH is sent. This signal is used to help UE B on the receiving side for channel estimation.
  • MP-RS can provide Channel estimation results of at least two ports;
  • the SCS of the carrier communicating on the current direct link is relatively small, and the time used for AGC is relatively small, and MP-RS has enough time for channel estimation, and the channel estimation accuracy is high at this time;
  • the MP-RS used in the "multi-port channel estimation” method multiplexes the MP-RS signal for channel estimation, and can obtain the channel matrix H value of the current Sidelink unicast communication, which saves DMRS signaling overhead and improves Improve resource utilization efficiency, and MP-RS can provide channel estimation results of at least two ports.
  • Example 8 (The SCS of MP-RS may be different from the SCS of PSCCH or PSSCH sent subsequently):
  • the sequence length of MP-RS is fixed, for example, the length is 255, but the SCS of MP-RS can be different from the SCS of PSCCH or PSSCH sent subsequently, so that MP-RS can cover the entire bandwidth:
  • MP-RS adopts a smaller SCS to ensure that there are enough subcarriers to accommodate the MP-RS sequence
  • the working bandwidth of V2X is 5MHz
  • the SCS configured for PSCCH or PSSCH is 15KHz
  • the SCS configured for PSCCH or PSSCH is 30KHz
  • the working bandwidth of 5MHz only has 12 RBs, which cannot accommodate the 255-long MP-RS sequence. Therefore, the MP-RS needs to use a smaller SCS, that is, 15KHz. It can be guaranteed that a 255-long MP-RS sequence can be accommodated in a 5MHz bandwidth.
  • the MP-RS uses a larger SCS to ensure that the MP-RS sequence can cover the entire bandwidth.
  • the working bandwidth of V2X is 20MHz
  • the SCS configured for PSCCH or PSSCH is 60KHz
  • the SCS configured for PSCCH or PSSCH is 15KHz
  • the working bandwidth of 20MHz will have 100 RBs, and the 255-long MP-RS sequence cannot cover the entire bandwidth, so the MP-RS needs to use a larger SCS, which is 60KHz. This ensures that the 255-long MP-RS sequence can cover the entire 20MHz bandwidth.
  • the SCS configuration method of the MP-RS sequence in this example is relatively flexible, and can be applied to various PSCCH or PSSCH SCS conditions and bandwidth conditions.

本申请主张在2019年4月30日在中国提交的中国专利申请号No.201910363911.3的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别是指一种信号处理方法、装置及通信设备。
背景技术
在相关技术中的长期演进(Long Term Evolution，LTE)智能网联汽车技术(vehicle-to-everything，V2X)技术中(版本Rel-14/Rel-15LTE V2X技术)，终端(user equipment，UE)用于自动增益控制或用于保护间隔的时长固定为一个符号，以完成进入模数转换器(analog to digital converter，ADC)的信号功率的调整，以及完成收发之间的转换。而用于数据解调的解调参考信号(demodulation reference signal，DMRS)也在一个子帧内占用了4个符号，参考信号开销比较高。而随着第五代(fifth generation，5G)新无线接入技术(New Radio，NR)的出现，促使车联网技术进一步发展，以满足新应用场景的需求。5G NR支持灵活的子载波间隔的配置，这就给NR V2X物理层结构的设计带来了新的挑战，原来固定占用一个符号的自动增益控制(automatic gain control，AGC)和保护间隔(guard period，GP)，可能不能满足需求，需要重新进行设计。而LTE V2X是广播或组播式通信模式，并没有单播模式。
具体如图1所示(图中a表示一个子帧)，横坐标是时域，每列代表一个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。纵坐标是频域。AGC固定占用第一个OFDM符号，GP固定占用最后一个OFDM符号，中间是数据或DMRS。可以看出，一个子帧14个符号中，AGC、GP以及DMRS共占用了6个符号，留给数据传输仅有8个符号；而在NR V2X中，为了满足NR V2X单播通信的需求，支持新引入的UE与UE之间的单 播通信模式，需要在NR V2X中进行基于用户的进行多端口的资源占用情况感知、自动增益控制、频偏估计、信道测量与信道估计等，也就是说，每个用户要使用可以区分开的信号或信道去完成自动增益控制、频偏估计与信道测量等功能，同时还需要避免用户间这些信号或信道的碰撞而导致的性能下降。这样就需要引入很多新的信号或信道来满足以上需求，增加了系统设计的复杂度以及信令开销，浪费资源。
也就是说，相关技术中NR V2X多端口直通链路通信中支持多种功能时存在资源消耗过多的问题。

下面对本公开实施例提供的所述信号处理方法进行进一步说明，第一通信设备以终端UE A为例，第二通信设备以UE B为例。
针对上述技术问题，本公开实施例提供了一种信号处理方法，主要涉及一种多端口多用途参考信号MP-RS，该信号“一人多能”且能够支持多端口，是一种多功能参考信号，可以同时支持至少两个端口的自动增益控制测量、频率偏移估计、信道状态信息测量、信道估计等功能；可使用在V2X系统的直通链路Sidelink通信中。
具体的：
(1)MP-RS是一种具有特定长度的特定序列，比如m序列(最长线性反馈移位寄存器序列)、Gold序列或ZC序列(零自相关序列)；序列长度在频域上占用整个工作带宽、部分工作带宽、整个载波带宽、部分载波带宽或配置的带宽部分BWP中的一个，在时域上占用至少一个符号。MP-RS的每个端口对应的序列长度均相同。
(2)MP-RS支持至少两个端口，可通过不同的序列、不同的循环移位、不同的时域位置和不同的频域位置中的至少一种来区分不同的端口。
(3)MP-RS的不同端口可对应不同的时域资源：MP-RS可采用梳状映射的方法进行时域映射，映射到预设工作带宽(整个工作带宽、整个载波带宽或者部分带宽)上，可通过时域梳齿位置区分端口，不同的端口占用不同的时域梳齿位置。典型的，配置两个时域梳齿对应到支持两个端口；配置四个时域梳齿对应到支持四个端口。
(4)MP-RS的不同端口可对应不同的频域资源：MP-RS可采用梳状映射的方法进行频域映射，映射到预设工作带宽(整个工作带宽、整个载波带宽或者部分带宽)上，可通过频域梳齿位置区分端口，不同的端口占用不同的频域梳齿位置。典型的，配置两个频域梳齿对应到支持两个端口；配置四个频域梳齿对应到支持四个端口。
(5)MP-RS的不同端口可对应不同的序列或循环移位：MP-RS可采用连续映射的方法(即按照子载波序号逐个映射的方式)进行时域映射，映射到预设工作带宽(整个工作带宽、整个载波带宽或者部分带宽)上，可通过 序列或循环移位区分端口，不同的端口可占用相同或不同的时域资源位置，但具有不同的序列或循环移位。
(6)MP-RS的不同端口可对应不同的序列或循环移位：MP-RS可采用连续映射的方法(即按照子载波序号逐个映射的方式)进行频域映射，映射到预设工作带宽(整个工作带宽、整个载波带宽或者部分带宽)上，可通过序列或循环移位区分端口，不同的端口可占用相同或不同的频域资源位置，但具有不同的序列或循环移位。
(7)MP-RS用于“多端口自动增益测量”：发送侧UE A(可在发送物理直通链路控制信道(physical sidelink control channel，PSCCH)之前)发送MP-RS，该信号用于帮助接收侧UE B用来做自动增益测量，避免信号强度波动过大导致ADC量化误差过大而导致的后续PSCCH和数据接收的误码率上升问题；并且，MP-RS可以支持多端口的自动增益分别测量，不同的端口具有不同的增益补偿量。
(8)MP-RS用于“多端口频率偏移估计”：发送侧UE A发送MP-RS，该信号用于帮助接收侧UE B用来做频率偏移估计，而MP-RS可以支持分别估计不同端口的频偏，具体的估计方案包括有：
a)针对MP-RS的每一个端口，将端口接收到的序列分成两段序列，两段序列分别与该端口所对应的本地序列做相关，然后计算相关处理之后的两段序列之间的相位差值，来获得该端口对应的初始频偏估计值；
b)在初始频偏估计值基础上增加频偏调整量得到频偏尝试值；具体需要至少一个频偏调整量，得到至少一个频偏尝试值；也可将初始频偏估计值作为一个频偏尝试值，对应得到一个频偏尝试值，总之最后得到至少两个频偏尝试值；
c)使用至少两个频偏尝试值去做相关运算，获得相关峰值(每个频偏尝试值对应一个相关峰值)，将至少两个频偏尝试值所对应的至少两个相关峰值的最大值所对应的频偏作为最佳频偏，对该端口接收到的序列进行频偏补偿。
d)对于不同端口，接收侧UE可以根据检测到的各个端口对应的相关峰值的最大值，设置不同的频偏补偿。
(9)MP-RS用于“多端口信道状态信息测量”：发送侧UE A发送多端 口MP-RS，该信号用于帮助接收侧UE B用来做信道状态信息测量(关于使用以下哪种方式，两个UE之间可提前约定好)：
a)对于不同时域资源或不同频域资源的测量方式：UE B可直接使用覆盖了全部工作带宽的梳齿状MP-RS进行信道状态信息测量，不同的端口占用不同的梳齿，UE B可以通过不同梳齿上的序列获得不同端口的信道信息测量结果；
b)对于不同序列或不同循环移位的测量方式：UE A发送多端口MP-RS，MP-RS的不同端口采用不同的序列或不同的循环移位，MP-RS可覆盖全部工作带宽，UB B收到多端口MP-RS之后，就可以获得整个工作带宽上不同端口的信道状态信息。
(10)MP-RS用于“多端口信道估计”：发送侧UE A发送多端口MP-RS，该信号用于帮助接收侧UE B用来做信道估计；MP-RS可以提供至少两个端口的信道估计结果。
a)在当前直通链路上进行通信的载波的子载波间隔SCS比较小时，用于自动增益控制AGC的时长较少，MP-RS有足够的时长用于信道估计，这时信道估计精度较高；
b)在当前直通链路上进行通信的载波的SCS比较大时，用于AGC的时长较长，MP-RS用于信道估计的时长较少或无法进行信道估计，这时需要新增DMRS完成信道估计。
具体的，以支持两个端口的MP-RS为例，关于MP-RS的发送如图4所示(图中a表示一个子帧，b表示预设工作带宽，PSFCH表示物理直通链路反馈信道(physical sidelink feedback channel))，所示，图4中符号#0中一个小方块(一个空白小方块或一个填充小方块)代表时域持续1个符号，频域为1个子载波。如图4所示，位于第一个符号的MP-RS采用梳状映射方式，映射到整个工作带宽上，共有两个梳齿，每个梳齿对应到一个端口。MP-RS除了可以完成AGC功能之外，还可以对该单播通信链路在通信之前进行信道状态测量，在通信中进行信道估计与频偏估计，这样可以通过MP-RS复用完成了多项功能，从而提高了Sidelink数据传输的误码率性能和资源利用性能。
下面对本公开实施例提供方案进行举例说明：
示例1(使用不同的时频资源-不同的时域资源和/或不同的频域资源来区分端口)：
MP-RS占用第一个符号，并且通过不同的梳齿来区分端口，每一个梳齿对应到一个端口。如图5所示(图中a表示一个子帧，b表示预设工作带宽)，第一个符号上的空白方块或填充方块在时域上占用一个符号，在频域上占用一个子载波。空白方块代表MP-RS的端口1，填充方块代表MP-RS的端口2上。接收侧终端可以通过这两个不同端口上映射的序列来获得这两个端口的相关信息，包括自动增益控制信息，频偏估计信息，信道状态测量信息，信道估计信息等。由于该MP-RS通过不同的时频资源映射了不同的端口测量序列，所以接收侧终端可以对不同端口分别进行测量并获得不同的测量信息。
本示例中这种多端口MP-RS序列的映射方法可以保证两个端口是完全正交的，测量结果准确。
示例2(使用相同的时频资源，不同的序列来区分端口)：
MP-RS占用第一个符号，并且通过不同的序列来区分端口，每一个序列对应到一个端口，为了减轻两个端口之间的干扰，两个端口所使用的序列可以是低相关的。如图6所示(图中a表示一个子帧，b表示预设工作带宽)，第一个符号上的空白方块在时域上占用一个符号，在频域上占用一个子载波。空白方块代表MP-RS的端口1和端口2。接收侧终端可以通过这两个不同端口上映射的序列来获得这两个端口的相关信息，包括自动增益控制信息，频偏估计信息，信道状态测量信息，信道估计信息等。由于该MP-RS通过不同的序列映射了不同的端口测量序列，所以接收侧终端可以对不同端口分别进行测量并获得不同的测量信息。
本示例中这种多端口MP-RS序列的映射方法平均每端口占用的时频资源较少，所能映射的端口数量较多。
示例3(使用相同的时频资源，相同的序列，不同的循环移位来区分端口)：
MP-RS占用第一个符号，并且可通过相同序列的不同循环移位来区分端口，每一个循环移位对应到一个端口，为了减轻两个端口之间的干扰，两个端口所使用的循环移位可以是低相关的。如图7所示(图中a表示一个子帧， b表示预设工作带宽)，第一个符号上的空白方块在时域上占用一个符号，在频域上占用一个子载波。空白方块代表MP-RS的端口1和端口2。接收侧终端可以通过这两个不同端口上映射的序列来获得这两个端口的相关信息，包括自动增益控制信息，频偏估计信息，信道状态测量信息，信道估计信息等。由于该MP-RS通过相同序列的不同循环移位映射了不同的端口测量序列，所以接收侧终端可以对不同端口分别进行测量并获得不同的测量信息。
本示例中这种多端口MP-RS序列的映射方法平均每端口占用的时频资源较少，所能映射的端口数量较多。
示例4(MP-RS用于“多端口自动增益测量”)：
MP-RS用于“多端口自动增益测量”：发送侧UE A可在发送PSCCH之前，先发送MP-RS，该信号用于帮助接收侧UE B用来做自动增益测量，避免信号强度波动过大导致ADC量化误差过大而导致的后续PSCCH和数据接收的误码率上升问题，并且MP-RS可以支持多端口的自动增益分别测量，不同的端口具有不同的增益补偿量。
a)当前直通链路上进行通信的载波的SCS较小时，这时可使用一个符号或半个符号的MP-RS即可完成AGC测量；
比如：当SCS＝15KHz时，对应到符号持续时长较大为67us，而AGC时长一般是固定的，大概是10～15us，所以这时使用半个符号的MP-RS即可完成AGC测量。当SCS＝60KHz时，对应到符号持续时长较大为17us，所以这时使用一个符号的MP-RS即可完成AGC测量。
b)当前直通链路上进行通信的载波的SCS较大时，需要使用两个或更多符号的MP-RS才能完成AGC测量；
比如：当SCS＝120KHz时，对应到符号持续时长较大为8us，而AGC时长一般是固定的，大概是10～15us，所以这时使用两个符号的MP-RS才能完成AGC测量。
c)剩余时长(一个符号中剩余部分)的MP-RS用来做对应端口的其它功能(除AGC外的任何功能)使用。
具体可通过频域离散映射，可以获得时域重复的MP-RS信号。这样当半个符号用作AGC时，剩余的半个符号的MP-RS可以用来做其它功能使用。
如图8左侧所示(图中a表示一个子帧，b表示预设工作带宽，c表示正交频分复用OFDM符号#0)，在发送端将MP-RS进行了频域梳状映射，在发送之前经过快速傅里叶反变换(inverse fast Fourier transform，IFFT)变换之后，从频域转换到时域，如图8右侧所示成为在一个符号内时域重复的信号，前半个符号和后半个符号的信息完全相同，这样在接收端接收到之后，可以使用前半个符号的MP-RS进行AGC测量，后半个符号的MP-RS进行其他功能使用，比如进行资源占用状态感知。
本示例这种MP-RS用于“多端口自动增益测量”的方法中MP-RS可以根据SCS的配置情况自适应的调整其时长，以便保证既有足够的时长用于ADC增益调整，又不会造成资源的浪费，并且MP-RS可以支持多端口的自动增益分别测量，不同的端口具有不同的增益补偿量。
示例5(MP-RS用于“多端口频率偏移估计”)：
MP-RS用于“多端口频率偏移估计”：发送侧UE A可以在发送物理直通链路控制信道PSCCH或物理直通链路共享信道(physical sidelink shared channel，PSSCH)之前，先发送MP-RS，该信号用于帮助接收侧UE B用来做频率偏移估计，而MP-RS可以支持分别估计不同端口的频偏，具体的估计方案包括有：
a)针对MP-RS的每一个端口，将端口接收到的序列分成两段，两段序列分别与该端口所对应的本地序列做相关，然后计算相关处理之后的两段序列之间的相位差值，来获得该端口对应的初始频偏估计值；
b)在初始频偏估计值基础上增加频偏调整量得到频偏尝试值；具体需要至少一个频偏调整量，得到至少一个频偏尝试值；也可将初始频偏估计值作为一个频偏尝试值，对应得到一个频偏尝试值，总之最后得到至少两个频偏尝试值；
c)使用至少两个频偏尝试值去做相关运算，获得相关峰值(每个频偏尝试值对应一个相关峰值)，将至少两个频偏尝试值所对应的至少两个相关峰值的最大值所对应的频偏作为最佳频偏，对该端口接收到的序列进行频偏补偿。
d)对于不同端口，接收侧UE可以根据检测到的各个端口对应的相关峰值的最大值，设置不同的频偏补偿。
本示例这种MP-RS用于“多端口频率偏移估计”的方法中复用MP-RS信号进行多端口频偏估计，可以获得当前发送数据的频率偏移，有利于后续的数据解调解码，并且对于不同端口，可以设置不同的频偏补偿量。
示例6(MP-RS用于“多端口信道状态信息测量”)：
MP-RS用于“多端口信道状态信息测量”：发送侧UE A可以在发送PSCCH或PSSCH之前，先发送MP-RS，该信号用于帮助接收侧UE B用来做信道状态信息测量，而MP-RS可以支持分别测量不同端口的信道状态信息：
a)对于不同时域资源或不同频域资源的测量方式：UE B可直接使用覆盖了全部工作带宽的梳齿状MP-RS进行信道状态信息测量，不同的端口占用不同的梳齿，UE B可以通过不同梳齿上的序列获得不同端口的信道信息测量结果；
b)对于不同序列或不同循环移位的测量方式：UE A发送多端口MP-RS，MP-RS的不同端口采用不同的序列或不同的循环移位，MP-RS可覆盖全部工作带宽，UB B收到多端口MP-RS之后，就可以获得整个工作带宽上不同端口的信道状态信息。
本示例这种MP-RS用于“多端口信道状态信息测量”的方法中复用MP-RS信号进行多端口信道状态信息测量，可以获得当前Sidelink单播通信的不同端口的信道状态信息，节省了信道状态信息-参考信号CSI-RS的信令开销，提升了资源利用效率。
示例7(MP-RS用于“多端口信道估计”)：
MP-RS用于“多端口信道估计”：发送侧UE A可以在发送PSCCH或PSSCH之前，先发送MP-RS，该信号用于帮助接收侧UE B用来做信道估计，MP-RS可以提供至少两个端口的信道估计结果；
a)在当前直通链路上进行通信的载波的SCS比较小时，用于AGC的时长较少，MP-RS有足够的时长用于信道估计，这时信道估计精度较高；
b)在当前直通链路上进行通信的载波的SCS比较大时，用于AGC的时长较长，MP-RS用于信道估计的时长较少或无法进行信道估计，这时需要新增DMRS完成信道估计。
本示例这种MP-RS用于“多端口信道估计”的方法中复用MP-RS信号进 行信道估计，可以获得当前Sidelink单播通信的信道矩阵H值，节省了DMRS的信令开销，提升了资源利用效率，并且MP-RS可以提供至少两个端口的信道估计结果。
示例8(MP-RS的SCS可以与随后发送的PSCCH或PSSCH的SCS不同)：
MP-RS的序列长度是固定的，比如长度是255，但MP-RS的SCS可以与随后发送的PSCCH或PSSCH的SCS不同，以便MP-RS能够正好覆盖整个带宽：
a)当PSCCH或PSSCH配置的SCS较大并且工作带宽较小的时候，MP-RS采用较小的SCS，以保证有足够的子载波来容纳MP-RS序列；
例如：当V2X的工作带宽是5MHz时，在PSCCH或PSSCH配置的SCS为15KHz时，有25个RB，每个资源块RB有12个子载波，可以容纳下255长的MP-RS序列，但在PSCCH或PSSCH配置的SCS为30KHz时，5MHz的工作带宽只有12个RB，就无法容纳下255长的MP-RS序列了，所以此时需要MP-RS采用较小的SCS，也就是15KHz，这样可以保证在5MHz带宽中容纳下255长的MP-RS序列。
b)当PSCCH或PSSCH配置的SCS较小并且工作带宽较大的时候，MP-RS采用较大的SCS，以保证MP-RS序列可以覆盖整个带宽。
例如：当V2X的工作带宽是20MHz时，在PSCCH或PSSCH配置的SCS为60KHz时，有25个RB，每个RB有12个子载波，255长的MP-RS序列可以覆盖整个20MHz带宽，但在PSCCH或PSSCH配置的SCS为15KHz时，20MHz的工作带宽就有100个RB，255长的MP-RS序列就无法覆盖整个带宽了，所以此时需要MP-RS采用较大的SCS，也就是60KHz，这样可以保证255长的MP-RS序列可以覆盖整个20MHz带宽。
本示例这种MP-RS序列的SCS配置方法比较灵活，可以适用于多种PSCCH或PSSCH的SCS情况与带宽情况。
在此说明，占用多于1个的符号的MP-RS的示例与上述类似，在此不再赘述，且占用的符号越多，得到的信息的精度越高。
