technical field

本公开涉及无线通信技术领域，特别涉及一种信道识别方法、设备及存储介质。The present disclosure relates to the field of wireless communication technologies, and in particular, to a channel identification method, device and storage medium.

Background technique

随着5G通信网络进入商业化阶段，为了获得更快和更可靠的数据传输，下一代(6G)通信技术已经处于研究状态。这些技术中，智能反射面(IRSs)引起了学术界和工业界的兴趣。As 5G communication networks enter the commercialization stage, next-generation (6G) communication technologies are already under research in order to achieve faster and more reliable data transmission. Among these technologies, intelligent reflective surfaces (IRSs) have attracted interest from both academia and industry.

智能反射板是一种新型的智能无源表面，利用超材料(Meta-materials)对表面的相位进行实时的控制，从而实现对入射波的反射角控制，形成不同方向的反射波束。The smart reflector is a new type of smart passive surface. Meta-materials are used to control the phase of the surface in real time, so as to realize the control of the reflection angle of the incident wave and form reflected beams in different directions.

图1为智能反射面传输模型示意图，如图所示，终端可以从IRS(Intelligent Reflecting Surface,智能反射面)上直接接收到信号，并且该信号的链路与从基站直接接收到的并不相同(多了信道(f _r))。在终端接收时，如果不能识别IRS反射的信号，会增加用户的盲检次数。 Figure 1 is a schematic diagram of the transmission model of the intelligent reflecting surface. As shown in the figure, the terminal can directly receive the signal from the IRS (Intelligent Reflecting Surface), and the link of the signal is not the same as that received directly from the base station. (More channels (f _r )). When the terminal receives the signal, if the signal reflected by the IRS cannot be identified, the number of blind detections of the user will be increased.

在相关系统中，尽管存在一些专用RNTI，但是并没有针对IRS场景的信道的识别方案，导致终端无法识别出IRS信道。In a related system, although there are some dedicated RNTIs, there is no channel identification scheme for the IRS scenario, so that the terminal cannot identify the IRS channel.

具体的，方案是通过定义一个专用于对IRS上的物理信道加扰的RNTI，实现终端能够针对IRS信道进行处理。IRS上的物理信道包括以下信道之一或者其组合：PBCH(物理广播信道，Physical broadcast channel)、PRACH(物理层随机接入信道，Physical Random Access Channel)、PDCCH(物理下行控制信道，Physical downlink control channel)、PDSCH(物理下行共享信道，Physical downlink shared channel)、PUSCH(物理上行链路共享信道，Physical Uplink Shared Channel)、PUCCH(物理上行控制信道，Physical Uplink Control Channel)信道等。Specifically, the solution is to define an RNTI dedicated to scrambling the physical channel on the IRS, so that the terminal can process the IRS channel. The physical channel on the IRS includes one of the following channels or a combination thereof: PBCH (Physical Broadcast Channel, Physical broadcast channel), PRACH (Physical Random Access Channel, Physical Random Access Channel), PDCCH (Physical Downlink Control Channel, Physical downlink control channel), PDSCH (Physical Downlink Shared Channel), PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) channels, etc.

下面对识别IRS链路的RNTI的方案的实施进行说明。The implementation of the scheme for identifying the RNTI of the IRS link will be described below.

为便于理解、区分以及说明，先对几个特征进行说明。For ease of understanding, distinction and description, several features are described first.

将IRS链路的RNTI称为：IRS-RNTI，也即IRS-RNTI是对IRS链路上PBCH、PRACH、PDCCH、PDSCH、PUSCH、PUCCH等信道加扰的RNTI统称。The RNTI of the IRS link is referred to as: IRS-RNTI, that is, the IRS-RNTI is a general term for the RNTI that scrambles PBCH, PRACH, PDCCH, PDSCH, PUSCH, PUCCH and other channels on the IRS link.

基站直视链路/信道：终端直接与基站进行交互信息的链路/信道，与经过IRS中继的链路/信道区分，如图1中的h _d信道。 The base station looks directly at the link/channel: the link/channel through which the terminal directly exchanges information with the base station, which is distinguished from the link/channel through the IRS relay, such as the _hd channel in Figure 1.

IRS链路/信道：终端经过IRS中继与基站进行交互信息的链路/信道，如图1中的f _r信道。也即，IRS链路是经过IRS中继的链路；和/或，IRS信道是经过IRS中继的信道。 IRS link/channel: The link/channel through which the terminal exchanges information with the base station through the IRS relay, such as the _fr channel in Figure 1. That is, the IRS link is a link through an IRS relay; and/or the IRS channel is a channel through an IRS relay.

实施中，终端根据所述RNTI识别出IRS信道后，还可以进一步包括如下处理之一或者其组合：In implementation, after the terminal identifies the IRS channel according to the RNTI, it may further include one or a combination of the following processes:

相应的，在基站侧则有，进一步包括基站在根据所述RNTI识别出的IRS信道上进行如下处理之一或者其组合：Correspondingly, on the base station side, it further includes that the base station performs one or a combination of the following processes on the IRS channel identified according to the RNTI:

具体的，通过IRS-RNTI区分信道，可以让终端或者基站针对IRS链路采用不同于基站直视信道的信道均衡或者补偿算法；也可以让终端或者基站针对IRS链路采用不同于基站直视信道的波束赋形方式和波束赋形系数。Specifically, by distinguishing channels by IRS-RNTI, the terminal or base station can use a channel equalization or compensation algorithm for the IRS link that is different from the direct-view channel of the base station; or the terminal or the base station can use a direct-view channel different from the base station for the IRS link. The beamforming method and beamforming coefficient of .

实施中，所述RNTI包括：In implementation, the RNTI includes:

也即，可以将IRS-RNTI分成公共的IRS-RNTI和专用IRS-RNTI。That is, the IRS-RNTI can be divided into a common IRS-RNTI and a dedicated IRS-RNTI.

公共IRS-RNTI用于IRS链路上发送的公共信息，接收对象为一个或者多个终端，比如广播信息，此时使用的广播信道使用公共IRS-RNTI加扰。这种广播信道传输的信息可以与宏站上的广播信道发送的信息不相同。比如接入过程中的信息(Msg0/1/2/3)等消息，可以在宏站上发送，也可以在IRS链路上发送，对于承载Msg0/1/2/3/4消息的不同信道使用IRS-RNTI加扰。The public IRS-RNTI is used for public information sent on the IRS link, and the receiving object is one or more terminals, such as broadcast information, and the broadcast channel used at this time is scrambled by the public IRS-RNTI. The information transmitted by this broadcast channel may be different from the information transmitted by the broadcast channel on the macro station. For example, messages such as information (Msg0/1/2/3) in the access process can be sent on the macro station or on the IRS link. For different channels carrying Msg0/1/2/3/4 messages Scrambling with IRS-RNTI.

专用IRS-RNTI用于IRS链路上对终端进行数据或者控制信息进行收发的信道进行加扰，物理信道可以为PDCCH、PDSCH、PUSCH、PUCCH。The dedicated IRS-RNTI is used to scramble the channel on the IRS link for the terminal to send and receive data or control information, and the physical channel may be PDCCH, PDSCH, PUSCH, and PUCCH.

对于公共IRS-RNTI的配置：可以为固定值，在协议中直接给出取值，也可以在基站的直视信道中进行配置。也即，所述公共RNTI是预先约定的，或，是基站通过终端直接与基站进行交互信息的信道配置的。For the configuration of the public IRS-RNTI: it can be a fixed value, and the value is directly given in the protocol, or it can be configured in the direct view channel of the base station. That is, the common RNTI is pre-agreed, or is configured by the base station through the channel through which the terminal directly exchanges information with the base station.

对于专用IRS-RNTI的配置：通过专用的控制信令或者信息对用户进行配置。也即，所述专有RNTI是基站通过专用的控制信令或者信息配置的。For the configuration of the dedicated IRS-RNTI: configure the user through dedicated control signaling or information. That is, the dedicated RNTI is configured by the base station through dedicated control signaling or information.

配置的方式可以通过RRC(无线资源控制，Radio Resource Control)信令或者PDCCH或者MAC CE(媒体接入控制控制单元；MAC：媒体接入控制，Media Access Control；CE：控制单元，Control Element)。The configuration method can be through RRC (Radio Resource Control, Radio Resource Control) signaling or PDCCH or MAC CE (Media Access Control Control Element; MAC: Media Access Control, Media Access Control; CE: Control Element, Control Element).

实施中，通过PDCCH配置所述RNTI时：In implementation, when the RNTI is configured through the PDCCH:

具体的，当基站需要终端通过IRS进行信息交互时，基站可以通过基站链路/信道进行配置，也可以通过IRS链路/信道进行配置。Specifically, when the base station needs the terminal to perform information exchange through the IRS, the base station may be configured through the base station link/channel, or may be configured through the IRS link/channel.

可以通过PDCCH信道中承载的DCI(下行控制信息，Downlink Control Information)实时配置终端使用的IRS-RNTI的类型和取值，以及有效的时间窗口或者时间周期等信息。可以一次配置一个或者多个类型的IRS-RNTI。The type and value of the IRS-RNTI used by the terminal, as well as information such as the valid time window or time period, can be configured in real time through the DCI (Downlink Control Information) carried in the PDCCH channel. One or more types of IRS-RNTIs can be configured at a time.

实施中，通过RRC信令配置所述RNTI时：In implementation, when configuring the RNTI through RRC signaling:

具体的，可以通过RRC信令配置给终端，在终端链路建立、重配置等过程中进行配置。配置终端使用的IRS-RNTI的类型和取值。可以一次配置一个或者多个类型的IRS-RNTI。Specifically, it can be configured to the terminal through RRC signaling, and the configuration can be performed in the process of terminal link establishment and reconfiguration. Configure the type and value of the IRS-RNTI used by the terminal. One or more types of IRS-RNTIs can be configured at a time.

实施中，通过MAC CE配置所述RNTI时：In implementation, when configuring the RNTI through the MAC CE:

具体的，可以通过定义IRS-RNTI MAC CE一次配置一个或者类型的IRS-RNTI的类型和取值，以及有效的时间周期。Specifically, by defining the IRS-RNTI MAC CE, you can configure the type and value of one or more types of IRS-RNTIs at a time, as well as the valid time period.

下面对IRS-RNTI的取值方案实施方式进行说明。The implementation manner of the value selection scheme of the IRS-RNTI will be described below.

具体实施中，所述RNTI取值范围为：0x0001-0xFFF2。In specific implementation, the value range of the RNTI is: 0x0001-0xFFF2.

具体的，IRS-RNTI的取值标识为〔XX，YY〕：XX和YY代表了IRS-RNTI可用的最大值和最小值。根据不同的类型，取值不相同。Specifically, the value of the IRS-RNTI is identified as [XX, YY]: XX and YY represent the maximum and minimum values available for the IRS-RNTI. Depending on the type, the value is different.

可以根据相关方案，在可用的取值中，定义IRS-RNTI相对应的RNTI。The RNTI corresponding to the IRS-RNTI may be defined in the available values according to the related scheme.

例如，可以将IRS-RNTI的定义放置在MAC的文本中，具体可以如下：For example, the definition of IRS-RNTI can be placed in the text of the MAC as follows:

加粗斜体字体为IRS-RNTI。Bold italic font is IRS-RNTI.

加粗为通用RNTI。Bold as generic RNTI.

斜体为固定公共RNTI。Fixed public RNTI in italics.

在相关方案中可用的取值中定义出IRS-RNTI。目前相关方案中可用的取值范围为：0xFFF3-0xFFFD，在其中取出若干个值。在已经分配的0x0001-0xFFF2中，也可定义SRI-RNTI。The IRS-RNTI is defined in the values available in the related scheme. The available value range in the current related scheme is: 0xFFF3-0xFFFD, in which several values are taken. In the already allocated 0x0001-0xFFF2, SRI-RNTI can also be defined.

所以，在0x0001-0xFFF2中增加SRI-RNTI为SRI(SRS资源指示，SRS resource indicator；SRS：探测参考信号，Sounding Reference Signal)专用RNTI。在0xFFF3-0xFFFD中增加SRI-SI-RNTI和SRI-P-RNTI。Therefore, the SRI-RNTI is added to 0x0001-0xFFF2 as a dedicated RNTI for SRI (SRS resource indicator, SRS resource indicator; SRS: Sounding Reference Signal, Sounding Reference Signal). Add SRI-SI-RNTI and SRI-P-RNTI in 0xFFF3-0xFFFD.
