  • BWP Bandwidth Part
  • CSI-RS can be further divided into beam management CSI-RS and CSI acquisition CSI-RS:
  • Beam management CSI-RS used for beam measurement and reporting in the beam management process.
  • the UE receives the CSI-RS transmitted by beamforming, measures its quality (received signal power), and selects the best transmitting and receiving beams. Therefore, beam management CSI-RS only needs to measure the receiving power (Reference Singal Receiving Power, PSRP).
  • PSRP Reference Singal Receiving Power
  • CSI acquires CSI-RS acquires CSI-RS transmission in two situations.
  • One is wide beamforming transmission.
  • Each antenna port of CSI-RS is wide beamforming transmission, covering the angular range of the entire cell. To obtain complete CSI, this transmission method requires a larger number of ports (maximum 32 ports).
  • the second is narrow beamforming transmission.
  • CSI-RS undergoes beamforming to obtain shaping gain and increase coverage distance. At this time, each antenna port transmits a narrow beam, so the angular range of spatial coverage is smaller.
  • multiple beamforming CSI-RSs often need to be configured and transmitted, but each beamforming CSI-RS can contain a smaller number of antenna ports.
  • NR uses a specially configured CSI-RS as a TRS. Specifically, NR uses a CSI-RS Resource Set (CSI-RS Resource Set) containing N (2 or 4) periodic CSI-RS resources to implement the function of TRS, where each CSI-RS resource is a port , occupying one OFDM symbol alone.
  • CSI-RS Resource Set CSI-RS Resource Set
  • the UE regards the antenna ports of different CSI-RS resources in the set as the same antenna port.
  • Precise time-frequency synchronization requires UE to continuously track and measure, so TRS is mainly transmitted periodically, and aperiodic TRS is used in some special scenarios.
  • DM-RS The function of DM-RS is to use DM-RS to perform channel estimation on uplink and downlink traffic channels and control channels to achieve coherent demodulation.
  • DM-RS and data use the same precoding process, so the channel estimated by the receiving end from DM-RS is directly used for data demodulation without additional indication of precoding-related information.
  • the NR data channel adopts the design of preamble DM-RS. In each scheduling time unit, the position of the DM-RS is as close as possible to the starting point of scheduling.
  • the UE After the UE receives the PDCCH and its scheduled PDSCH, it needs to complete demodulation and decoding within a certain period of time in order to feed back the hybrid automatic repeat request on the Physical Uplink Control Channel (PUCCH) resource allocated by the base station.
  • Response Hybrid Automatic Repeat Request Acknowledgment, HARQ-ACK
  • NR can configure additional DM-RS for the UE based on the prefix DM-RS.
  • Each set of additional DM-RS patterns is a repetition of the preceding DM-RS. Therefore, consistent with the prefix DM-RS, each set of additional DM-RS can occupy up to two consecutive symbols.
  • the base station can configure 1 to 3 sets of additional DM-RS symbols for the UE.
  • Phase noise Phase Noise (Phase Noise, PN) is mainly introduced by the local oscillation circuit. Phase noise will destroy the orthogonality between subcarriers in the OFDM system and introduce inter-subcarrier interference. At the same time, phase noise introduces the same Common Phase Error (CPE) on all subcarriers, causing the modulation constellation points on all subcarriers to rotate at a fixed angle. Phase noise has a significant impact on system performance in the high frequency band, but the subcarrier spacing used by NR in the high frequency band is larger, and the inter-subcarrier interference caused by phase noise has little impact on the demodulation performance. Therefore, NR designed PT-RS, mainly Implement estimation and compensation for CPE.
  • CPE Common Phase Error
  • PT-RS is transmitted within the time-frequency resource range occupied by the business channel and is used in conjunction with DM-RS.
  • PT-RS is mapped on OFDM symbols without DM-RS, and the phase change on each OFDM symbol is estimated for phase compensation. Since the CPE is the same across the entire frequency band, ideally, one subcarrier is used to transmit PT-RS to achieve the purpose of CPE estimation and compensation. However, due to the influence of interference and noise, estimating CPE using only one subcarrier may have a large estimation error. Therefore, more subcarriers are needed to transmit PT-RS to improve the accuracy of CPE estimation.
  • NR uses a uniform density of occupying one subcarrier in several PRBs to transmit PT-RS.
  • Frequency domain density is roughly inversely proportional to scheduling bandwidth. The larger the scheduling bandwidth, the lower the density.
  • PT-RS can occupy 1 OFDM symbol for transmission in every 1/2/4 OFDM symbols.
  • the time domain density of PT-RS is related to the MCS level used by the traffic channel. The higher the MCS level, the greater the time domain density. This is because the demodulation performance of high-level modulation and coding scheme (Mission Critical Service, MCS) is more sensitive to phase noise and requires relatively more accurate phase Bit noise estimation and compensation.
  • MCS Mobility Critical Service
  • SRS Sounding Reference Signal
  • the main functions of SRS are uplink channel status information acquisition, downlink channel status information acquisition and beam management.
  • the SRS for obtaining uplink channel status information can be further divided into two types according to the corresponding transmission scheme (codebook and non-codebook). Therefore, NR supports 4 types of SRS with different functions.
  • SRS with different functions are managed and configured in the form of SRS resource collection.
  • the base station can configure multiple SRS resource sets for the UE, and each resource set configures its functions through high-layer signaling.
  • NR SRS uses of NR SRS have been expanded compared to LTE.
  • the NR system has a greater demand for SRS resources. Therefore, NR allows the last 6 symbols of each uplink time slot to be used for SRS transmission.
  • Each SRS resource can occupy 1, 2 or 4 consecutive OFDM symbols in a time slot.
  • the purpose of allowing SRS to be transmitted on multiple OFDM symbols is to extend uplink coverage.
  • the same SRS resource can be repeatedly transmitted on the same subband on multiple OFDM symbols, or can be transmitted by frequency hopping between different subbands.
  • An SRS resource can include 1, 2 or 4 antenna ports, which are configured by the base station according to the UE's capabilities. Multiple antenna ports are multiplexed in a code division multiplexing (CDM) or frequency division multiplexing (Frequency-division Multiplexing, FDM) + CDM manner. SRS transmission in the frequency domain adopts a comb structure, and the spacing between subcarriers occupied by SRS can be configured as 2 or 4.

  • the UE can transmit SRS in a shaped or unshaped manner.
  • the UE measures the downlink channel, uses channel reciprocity to obtain the uplink shaping weight, and transmits the SRS corresponding to the beamforming.
  • SRS is sent separately using the UE's candidate transmit beams, and the base station performs measurements and selects the appropriate UE transmit beam.
  • whether the SRS is shaped depends on the configuration of the base station and the implementation structure of the UE. If the base station only configures one SRS resource for the UE for codebook transmission, the UE usually uses a wide beam to transmit the SRS, and the beamforming (precoding) of data transmission is indicated by the base station in the form of TPMI (Transmission PMI).

为使本领域技术人员能够更好地理解本公开实施例，先进行如下说明。
物理信道：对应于一系列(Resource Element，RE)的集合，需要承载来自高层的信息称为物理信道；如物理下行控制信道(Physical Downlink Control Channel，PDCCH)，该PDCCH承载下行控制信息(Downlink Control Information，DCI)、物理下行共享信道(Physical Downlink Share Channel，PDSCH)承载数据。
物理信号：对应于物理层使用的一系列RE，但这些RE不传递任何来自高层的信息，如参考信号，同步信号。
一：物理信号
从功能上划分：
NR下行物理信号包括信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、解调参考信号(Dedicated demodulation reference signals，DM-RS)、时频跟踪参考信号(Tracking Reference Signal，TRS)、相位噪声跟踪参考信号(Phase noise Tracking Reference Signal，PT-RS)、无线资源管理(Radio Resource Management，RRM)测量参考信号、无线链路监测(Radio Link Monitoring，RLM)测量参考信号等。
NR上行物理信号包括探测参考信号(Sounding Reference Signal，SRS)、解调参考信号(DM-RS)、相位噪声跟踪参考信号(PT-RS)等。其中，上行DM-RS和PT-RS与下行的设计基本相同。
下面分别简略介绍5G NR的参考信号：
信道状态信息参考信号(CSI-RS)
CSI-RS的天线端口数最高可以达到32，包括1、2、4、8、12、16、24和32，支持大规模天线技术的CSI测量，CSI-RS的时频资源位置由高层信令灵活配置，包括所占用的正交频分复用(Orthogonal frequency division multiplex，OFDM)符号和物理资源块(Physical Resource Block，PRB)。CSI-RS可以在一个时隙内的任意OFDM符号上传输，可以在带宽部分(Bandwidth  Part，BWP)内任意的连续PRB内传输(最小带宽为24个PRB)，对于给定的天线端口数量，CSI-RS在一个PRB内的图样也不再有固定的形式，而是由基站根据可用时频资源灵活配置。
CSI-RS可以进一步划分为波束管理CSI-RS和CSI获取CSI-RS：
波束管理CSI-RS：用于波束管理过程中的波束测量和上报，UE接收波束赋形传输的CSI-RS，对其质量进行测量(接收信号功率)，选出最佳的发送和接收波束，所以波束管理CSI-RS仅需要测量接收功率(Reference Singal Receiving Power，PSRP)。
CSI获取CSI-RS：CSI获取CSI-RS的传输分为两种情况。其一是宽波束赋形传输，CSI-RS的每个天线端口都是宽波束赋形传输，覆盖整个小区的角度范围。为获取完整的CSI，这种传输方式需要较大的端口数量(最大32端口)。其二是窄波束赋形传输，CSI-RS经过波束赋形以获得赋形增益，增加覆盖距离。此时每个天线端口均为窄波束传输，因此空间覆盖的角度范围较小。为了覆盖一个小区内的所有UE，往往需要配置并传输多个波束赋形CSI-RS，但是每个波束赋形CSI-RS包含的天线端口数量可以较少。
2.时频跟踪参考信号(TRS)
LTE系统中CRS在每个子帧发送，UE可以通过测量CRS实现高精度的时频同步。持续周期性发送的参考信号会带来前向兼容性问题和不必要的功率浪费，因此NR引入了可以根据需要配置和触发的TRS实现时频精同步。因为CSI-RS的结构和配置方式都足够灵活，NR将一种特殊配置的CSI-RS作为TRS。具体地，NR将包含N(2或4)个周期性CSI-RS资源的CSI-RS资源集合(CSI-RS Resource Set)用于实现TRS的功能，其中每个CSI-RS资源都是一端口，单独占据一个OFDM符号。UE将集合内的不同CSI-RS资源的天线端口视为同一个天线端口。时频精同步需要UE持续地进行跟踪和测量，因此TRS以周期性传输为主，在部分特殊场景下配合使用非周期TRS。
3.解调参考信号(DM-RS)
DM-RS作用是使用DM-RS进行上下行业务信道和控制信道进行信道估计，实现相干解调。DM-RS与数据采用相同的预编码处理，因此接收端从DM-RS估计出来的信道直接用于数据解调，无须额外指示预编码相关的信息。 为了降低解调和解码时延，NR数据信道(PDSCH/PUSCH)采用了前置DM-RS的设计。在每个调度时间单位内，DM-RS的位置都尽可能地靠近调度的起始点。UE接收到PDCCH及其调度的PDSCH之后，需要在一定的时间内完成解调和解码，以便在基站为其分配的物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源上反馈混合自动重传请求应答(Hybrid Automatic Repeat Request Acknowledgement，HARQ-ACK)信息。
为了兼顾对中高移动速率的支持，NR在前置DM-RS的基础上，可以为UE配置附加DM-RS。每一组附加DM-RS的图样都是前置DM-RS的重复。因此，与前置DM-RS一致，每一组附加DM-RS最多可以占用两个连续的符号。根据移动速率的不同，基站可以为UE配置1～3组附加DM-RS符号。
4.相位噪声跟踪参考信号(PT-RS)
相位噪声(Phase Noise，PN)主要由本地振荡电路引入。相位噪声会破坏OFDM系统中各子载波之间的正交性，引入子载波间干扰。同时，相位噪声在所有子载波上引入相同的公共相位误差(Common Phase Error，CPE)，从而导致所有子载波上的调制星座点以固定角度旋转。相位噪声在高频段对系统性能有明显影响，但是NR在高频段使用的子载波间隔更大，相位噪声引起的子载波间干扰对解调性能影响不大，因此NR设计了PT-RS，主要实现对CPE的估计和补偿。
PT-RS在业务信道占用的时频资源范围内传输，配合DM-RS使用。PT-RS映射在没有DM-RS的OFDM符号上，估计出各个OFDM符号上的相位变化，用于相位补偿。由于CPE在整个频带上相同，理想情况下，一个子载波用于传输PT-RS就可以达到CPE估计和补偿的目的。然而，由于干扰和噪声的影响，仅用一个子载波估计CPE可能会存在较大的估计误差，因而需要更多的子载波来传输PT-RS，以提升CPE估计的精度。NR采用若干个PRB内占用一个子载波的均匀密度传输PT-RS。频域密度与调度带宽大致成反比例，调度带宽越大，密度越低。时域内，PT-RS可以在每1/2/4个OFDM符号占用1个OFDM符号传输。PT-RS的时域密度与业务信道所使用的MCS等级相关，MCS等级越高，时域密度越大。这是因为高等级调制和编码方案(Mission Critical Service，MCS)的解调性能对相位噪声更敏感，需要相对更精确的相 位噪声估计和补偿。
5.探测参考信号(SRS)
SRS的主要功能是上行信道状态信息获取、下行信道状态信息获取和波束管理。获取上行信道状态信息的SRS按照对应的传输方案(码本和非码本)不同可以进一步分为两种，因此NR支持4种不同功能的SRS。不同功能的SRS以SRS资源集合的方式进行管理和配置。基站可以为UE配置多个SRS资源集合，每个资源集合由高层信令配置其功能。
NR SRS的用途相对于LTE得到了扩充，同时由于用户数量和业务量的提升，NR系统对SRS资源的需求量更大，因此NR允许每个上行时隙的最后6个符号用于SRS传输。每个SRS资源在一个时隙内可以占用1个、2个或4个连续的OFDM符号。允许SRS在多个OFDM符号上传输的目的是扩展上行覆盖。同一个SRS资源在多个OFDM符号上可在相同的子带上重复传输，也可以在不同的子带间跳频传输。
一个SRS资源可以包括1个、2个或4个天线端口，由基站根据UE的能力配置。多个天线端口之间以码分复用(CDM)或者频分复用(Frequency-division Multiplexing，FDM)+CDM的方式复用。频域内SRS传输采用梳状结构，SRS占用的子载波间的间距可以配置为2或者4。
UE可以采用赋形或者非赋形方式传输SRS。对于非码本传输，UE对下行信道进行测量，利用信道互易性获得上行的赋形权值，并传输对应波束赋形的SRS。对于波束管理，SRS要用UE的候选发送波束分别发送，由基站进行测量并选择合适的UE发送波束。对于码本传输方案，SRS是否赋形取决于基站的配置和UE的实现结构。如果基站只为UE配置了一个SRS资源用于码本传输，UE通常用宽波束传输该SRS，数据传输的波束赋形(预编码)由基站以TPMI(Transmission PMI)的形式指示。如果基站为UE配置了2个SRS资源，则UE可以用2个不同的窄波束分别传输这2个SRS资源，数据传输的波束赋形由基站指示给UE的SRS资源索引(SRS Resource Indicator，SRI)和TPMI共同确定。
在时分复用(Time Division Duplex，TDD)系统中，SRS的一个重要功能是获取下行信道状态信息。UE的接收链路往往多于发射链路，因此UE一 次发送的SRS不能获得完整的下行信道信息。这种情况下，NR支持UE的SRS天线切换，即UE按照预定义的规则，在不同的时间用不同的天线发送SRS，以使基站能获得完整的下行信道状态信息。
二：物理信道
物理信道对应于一组特定的时/频资源，用于承载高层映射的传输信道。每个传输信道均映射到一个物理信道。物理下行控制信道(Physical Downlink Conrol Channel，PDCCH)承载下行控制信息(Downlink Control Information，DCI)，用于为UE提供下行接收和上行传输的必要信息，例如资源分配信息等。物理上行控制信道(Physical Uplink Control Channel，PUCCH)承载上行控制信息(Uplink Control information，UCI)，用于向基站报告UE的状态，如HARQ接收的状态、信道状态信息等。
NR定义的物理信道包括以下几个：
物理下行共享信道(Physical Downlink Shared Channel，PDSCH)主要用于下行单播数据的传输，也可以用于寻呼消息和系统消息的传输。PDSCH在天线端口1000～1011上传输。
物理广播信道(Physical Broadcast Channel，PBCH)承载UE接入网络所需的最小系统信息的一部分。PBCH的天线端口为4000。
物理下行控制信道(PDCCH)用于传输DCI，主要是UE接收PDSCH和传输物理上行共享信道(Physical Uplink Shared Channel，PUSCH)所需的调度信息，也可以传输时隙格式指示(Slot Format Indicator，SFI)和抢占指示(Preemption Indication，PI)等。PDCCH的天线端口为2000。
物理上行共享信道(PUSCH)对应于PDSCH的上行物理信道，用于传输上行业务数据，还可以用来承载UCI。PUSCH在天线端口1000～1003上传输。
物理上行控制信道(PUCCH)承载UCI，反馈HARQ-ACK信息，指示下行的传输块是否正确接收；上报信道状态信息；在有上行数据到达时请求上行资源。PUCCH的天线端口为2000。
物理随机接入信道(Physical Random Access Channel，PRACH)用于随机接入过程，天线端口为4000。
现有新空口(New Radio,NR)系统按照其自身的需求设计了不同功能的物理信道和物理信号，其符合现有NR系统架构。但对于未来通信系统，如6G系统，不仅限于传统基站，带有通信模块的移动节点或终端设备等都有可能作为用户进行端到端通信的网络接入点，其网络架构是十分灵活的，现有NR系统中的参考信号和物理信道并不能适应未来通信系统架构。
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。

在本公开的第一实施例中，假设终端向接入点发送目标信号，该目标信号由一级序列组成，仅承载第一信息。终端(此终端为常规作用的终端，是不作为接入点的终端设备)向接入点(Access Point，AP)发送目标信号，所述目标信号承载第一信息，包括部分或完整的第一标识信息。所述第一标识信息具有全球唯一的特性；所述第一标识由多级第二标识组成，所述第二标识包括国家级标识和/或地区级标识和/或本地级标识和/或个体级标识和/或服务级标识。通过所述个体级标识指示节点的节点类型，如终端，所述服务级标识指示终端的服务类型，以实现所述第一标识指示节点类型和/或服务类型。
接入点AP接收到终端发送的目标信号，根据第一信息得知终端部分或完整的第一标识信息。如果终端每次发送的目标信号承载的第一信息只包括部分的第一标识信息，接入点AP需要接收终端多个目标信号才可获得完整的第一标识信息，所述多个目标信号分别携带部分第一标识信息。接入点AP得到终端完整的第一标识信息，可唯一地确定终端。

对于接入点切换指示：目标信号用于接入点切换指示，第二信息至少包括节点切换指示信息。第二终端接收到目标信号，根据目标信号携带的第一信息唯一地确定第一终端，根据目标信号携带的第二信息进行接入点的切换。利用本实施例，在小区覆盖受限的情景，接入点可先将第二终端的接入点切换指令发送给第一终端，然后第一终端向第二终端发送目标信号，来指示第二终端的切换，以此保证接入点切换指令的可靠性。
