- TDD mode satellite communication may include the following features: in terms of antenna structure, the transmitter and receiver share a group of antennas, which can simplify the satellite or terminal structure; in terms of frequency allocation, it supports compatibility between satellite and terrestrial mobile communications, and can reuse the terrestrial industry chain; in terms of transmission delay, it is larger than the delay of FDD mode, and a protection interval is required between the uplink and downlink links, which may cause resource waste; in terms of scheduling timing, the uplink and downlink time slots are not continuous, and the scheduling timing is strictly required; in terms of interference management, there is interference between the uplink and downlink links. Based on the characteristics of TDD mode satellite communication, if the TDD mode is used on a large scale in satellite communication systems, remote interference problems may occur.
- RI is interference caused by air tropospheric waveguide.
- the downlink transmission power of the base station in TDD mode is usually much higher than the uplink transmission power.
- air stratification will form a waveguide in the troposphere.
- the downlink transmission signal can enter the troposphere waveguide and propagate hundreds of kilometers with low propagation loss, and interfere with the uplink of the distant base station (such as the base station on the lower side of the figure).
- RI can last from several minutes to several hours, and the propagation distance can even exceed 300km, causing long-term and large-area interference to the TDD mobile communication system.
- D represents the downlink symbol
- U represents the uplink symbol
- GP represents the guard interval.
- the uplink signal of an earth station may generate RI to the downlink signals of other earth stations.
- the uplink signal of earth station A enters the tropospheric waveguide and is transmitted to earth station V hundreds of kilometers away through the tropospheric waveguide.
- Earth station V is downlinking with a satellite. At this time, it not only receives the downlink signal of the satellite, but also receives the uplink signal of the distant earth station A, causing RI to the satellite downlink.
- Iridium frame structure shown in Figure 1d as an example, assuming that the satellite is Iridium, V represents the victim earth station, A1 ⁇ AN represent N different interfering earth stations, and due to the transmission delay (Transmission delay) caused by the tropospheric waveguide, different interfering earth stations will generate RI to the victim earth station.
- Iridium is a commercial satellite system using TDD mode.
- the presence of RI in a TDD system may be due to many reasons.
- the frequency range in which the atmospheric duct effect occurs is usually 0.3-30 GHz, and the signal frequency of the earth station overlaps with a large part of this range.
- the maximum transmission power of a 6GHz base station in an urban microcell scenario (Umi) is about 52 dBm, while the earth station transmission power is as high as hundreds or even kilowatts, which is prone to interference.
- antenna pointing antennas pointing to high altitudes and relatively open areas are prone to long-range interference.
- the upward tilt of the base station beam will increase the possibility of long-range interference in the ground mobile communication system; the earth station beam points to the sky, and beams with lower elevation angles are also prone to long-range interference.
- the RIM architecture in the ground communication system includes a centralized architecture and a distributed architecture.
- the network element node (OAM) plays a unified scheduling role, and the OAM can collect information about the interfering earth station and the disturbed earth station, and generate and implement appropriate interference avoidance schemes.
- the transmission and stop of the reference signal in the RIM and the generation of the interference avoidance scheme all need to be responsible for the OAM, and the degree of dependence on the OAM is relatively high.
- the distributed architecture (Framework-1) shown in FIG1f, interference avoidance is achieved based on air interface signal transmission between earth stations. The structure is relatively simple and does not rely on the coordination of OAM.
- the interferers and interfered parties are earth stations in the user role.
- Both the centralized architecture and the distributed architecture mentioned above cannot meet the latency requirements of satellite communication.
- the interference avoidance strategy of the centralized architecture is completely determined by the OAM configuration, and the construction and scheduling of this architecture are complex; the satellite communication latency is larger than that of the ground, and it is difficult to meet the highly dynamic processing requirements in terms of time if it completely relies on satellite scheduling.
- the distributed architecture the information that can be exchanged between the interfered base station and the interfering base station is limited, and in satellite communication, the earth station cannot complete the interference avoidance based on air interface signal transmission by itself. Therefore, for the RI problem that may exist in the satellite communication system, it is necessary to provide an effective interaction method to avoid interference.
- FIG2a is an interactive schematic diagram of a RIM method provided according to an embodiment of the present disclosure. As shown in FIG2a, the RIM method of the embodiment of the present disclosure includes:
- Step S2101 the first network device 101 determines that an RI exists.
- the first network device 101 is a disturbed earth station, which may be subject to remote interference from one or more second network devices 103 due to the atmospheric duct phenomenon.
- the second network device 103 is an interfering earth station or a remote base station.
- the first network device 101 determines that RI exists when interference noise meeting a set characteristic is detected.
- the set feature is, for example, that the interference noise presents a tilt feature as shown in Figure 2b within a set period of time.
- the interference noise presents a tilt feature as shown in Figure 2b within a set period of time.
- FIG2c is a schematic diagram of the interference noise (IOT) distribution of the victim base station (Victim) in the ground network.
- IOT interference noise
- RI is caused by the cumulative signals of multiple interfering base stations (Aggressor1 to Aggressor4) at different distances. The farther the interfering base station is from the victim base station, the longer the propagation time of its downlink signal will be, and the more uplink symbols (UL symbol) will affect the victim base station.
- the RI received by the first network device 101 is caused by the cumulative signals of multiple second network devices 103 at different distances. The farther the second network device 103 is from the first network device 101, the more downlink symbols (DL symbol) will affect the first network device 101.
- the first network device 101 may start detecting whether interference exists only after connecting to the satellite gateway 102 . To save power consumption, the first network device 101 may not detect interference when no connection is established with the satellite gateway 102 .
- Step S2102 the first network device 101 sends report information to the satellite gateway 102 .
- the report information is used to indicate that the first network device 101 is subject to remote interference RI.
- the first network device 101 sends a report message to indicate that it has detected a “tilted” RI. After sending the report message, the satellite gateway 102 needs to determine the second network device 102 that may generate RI for the first network device 101.
- the second network device 103 will know that it is interfering only when it receives the first RS.
- the first network device 101 cannot send the first RS spontaneously and needs to report to the satellite gateway first.
- the satellite gateway 102 needs to ensure that the second network device 103 has a downlink time slot to receive the first RS.
- Step S2103 the satellite gateway 102 sends second configuration information to at least one second network device 103 .
- the satellite gateway 102 after receiving the report information, the satellite gateway 102 needs to determine one or more second network devices 103 that may cause interference.
- the at least one second network device 103 is determined by the satellite gateway 102 according to the location of the first network device 101 .
- the satellite gateway 102 determines the second network device 103 that potentially causes interference within a certain range near the location of the first network device 101 based on prior information or experience information.
- the second network device 103 when the second network device 103 experiences an increase in long-range interference, it may believe that it is interfered with, but actually receives the first RS signal. Therefore, it is necessary for the satellite gateway 102 to configure the second network device 103, which is a potential interferer, to start detecting the first RS.
- the first RS is used to instruct the second network device 103 to generate RI for the first network device 101 and calculate how many uplink resources of the first network device 101 are interfered.
- the second RS is used to detect whether the first network device still has RI after the second network device performs RI avoidance behavior.

- the configuration of the first RS or the second RS for the RIM may satisfy at least one of the following:
- Multiple RS transmission opportunities can be semi-statically configured within the transmission cycle to distinguish RIM RS resources.
- the transmission position of the RS is fixed in the last X symbols before the UL transmission boundary.
- the first RS or the second RS needs to be distinguished in time and sequence and configured separately;
- the multiple second RS configurations share the same frequency resources and sequence.
- the network device is configured with multiple RSs for RIM:
- Network devices can perform multiple RIM RS configurations within a configuration cycle

- the second configuration information is applicable to the second network device 103 that receives the configuration.
- the second network device 103 receives the second configuration information and may execute step S2104.
- Step S2104 The second network device 103 monitors the first RS according to the second configuration information.
- the second network device 103 that receives the second configuration information monitors or detects the first RS, while the second network device 103 that does not receive the second configuration information may not detect the first RS.
- the second network device 103 monitors or detects the second RS at a corresponding time-frequency position according to the time-frequency position of the first RS configured by the second configuration information.
- the second network device 103 starts to monitor or detect the first RS after receiving the second configuration information.
- the second network device 103 when the second network device 103 starts to monitor the first RS, the second network device 103 believes that the first network device 101 has received the first configuration information sent by the satellite gateway 102; or,
- the first network device 101 receives the first configuration information, wherein the second network device 103 does not generate an RI for the first network device 101; or,
- the first network device 101 When the second network device 103 starts to monitor the first RS, the first network device 101 does not receive the first configuration information or does not start to send the first RS; wherein the first configuration information is used to configure the first reference signal RS and the second RS, and is used to instruct the first network device to start sending the first RS.
- the second network device 103 monitors the first RS within the second time window T2.
- the second network device 103 can receive the first RS within T2, it means that the second network device 103 generates an RI for the first network device 101, and the avoidance behavior of step S2107 needs to be performed.
- the second network device 103 does not receive the first RS within T2, or the second network device 103 still does not monitor or detect the first RS when the preset T2 is exceeded, it means that the RI generated by the second network device 103 has been eliminated or no RI is generated for the first network device 101.
- the second network device 103 can stop monitoring or detecting RS-1 and restore the original configuration.
- Step S2105 the satellite gateway 102 sends first configuration information to the first network device 101 .
- the first configuration information is used to configure the first reference signal RS and the second RS, and is used to instruct the first network device 101 to start sending the first RS.

- FIG6 is a flow chart of the method of the embodiment of the present disclosure.
- the method of the embodiment of the present disclosure proposes a signaling interaction mechanism suitable for a TDD satellite communication system, which can not only meet the delay requirements of the satellite communication system, but also have a certain degree of adaptive capability to alleviate the long-range interference problem in TDD satellite communication.
- the disturbed earth station 101 detects the long-range interference
- the disturbed earth station reports the interference to the satellite gateway (Gateway), and the satellite gateway makes a decision and configures the timing of transmitting and monitoring RS-1 or RS-2 signals for the disturbed earth station and the disturbing earth station.
- the configuration of RS-1 and RS-2 can reuse related protocols.
- the victim earth station corresponds to the first network device 101 of the aforementioned embodiment
- the aggressor earth station corresponds to the second network device 103 of the aforementioned embodiment
- RS-1 corresponds to the first RS of the aforementioned embodiment
- RS-2 corresponds to the second RS of the aforementioned embodiment.
- the method may include the following steps Step 0 to Step 8:
- Step 0 The atmospheric duct phenomenon occurs and the disturbed earth station detects the "tilted" long-range interference characteristics.
- Terrestrial remote interference is caused by the cumulative signals from multiple remote base stations at different distances. The farther the base station is, the longer the propagation time of its downlink signal will be, and the more uplink symbols will be affected by the interfered base station.
- the interference noise (IOT) distribution of the interfered base station is shown in Figure 2c.
- the interfered earth station in the TDD satellite communication system will also be interfered by the cumulative signals from multiple remote earth stations at different distances.
- Step 1 After the disturbed earth station detects the "tilted" long-range interference, it reports to the satellite gateway and starts waiting for the gateway to configure RS-1 and RS-2 signals within the time window T1.
- Step 2 Based on the prior information, the satellite gateway configures RS-1 and RS-2 signals and interference avoidance procedures for potential interfering earth stations within a certain range near the disturbed earth station, and notifies them that they can start detecting RS-1.
- Step 3 The interfering earth station starts to detect RS-1 according to the configuration of the satellite gateway. If RS-1 is not detected within the preset time window T2, it means that the earth station is not currently interfering with other earth stations. Then jump to Step 8, stop detecting RS-1, and restore the original configuration (original config).
- Step 4 The satellite gateway configures RS-1, RS-2 signals and interference avoidance procedures for the affected earth station, and notifies the affected earth station that it can start RS-1 transmission and RS-2 detection.
- Step 5 The disturbed earth station starts RS-1 transmission and detects the interfering earth station RS-2.
- Step 6 After the interfering earth station receives RS-1, it initiates a long-range interference avoidance plan (such as increasing the protection interval, reducing the transmission power, etc.); then it sends RS-2 to test whether the long-range interference phenomenon of the disturbed earth station still exists.
- a long-range interference avoidance plan such as increasing the protection interval, reducing the transmission power, etc.
- Step 7-1 If the disturbed earth station does not detect RS-2 in Step 5;
- Step 7-2 If the disturbed earth station can still detect RS-2 in Step 5, it means that there is still long-distance interference from the earth station. At this time, the disturbed earth station continues to transmit RS-1 and returns to Step 5.
- Step 8-1 If the interfering earth station cannot receive RS-1 within the time window T2 of Step 3, it means that the long-range interference has been eliminated. The interfering earth station stops detecting RS-1 and restores the original configuration.
- Step 8-2 If the interfering earth station can still receive RS-1 within the time window T2 of Step 3, it means that it is still interfering with other earth stations, so continue to implement the long-range interference avoidance plan and return to Step 6.
- Step 1 For the signaling process Step 1, Step 2 and Step 4, there are the following descriptions:
- Step 1 RS-1 is used to inform the interfering earth station that it is interfering with the victim earth station and to estimate how many UL resources of the victim earth station are interfered with; RS-2 is used to test whether the interference still exists after the interfering earth station implements the interference mitigation plan. If the waiting time of the victim earth station exceeds the preset time window T1, the long-range interference phenomenon has not disappeared, and the service is urgent, it stops waiting and considers other solutions such as satellite switching to avoid interference.
- Step 2 the interfering earth station needs to be configured and start detecting RS-1. There are two considerations:
- the interfering base station can have DL time slots to receive the configuration and can receive the RS-1 sent by the victim earth station;
- the victim earth station may send RS-1 but the interfering earth station has not started receiving it, resulting in power waste of the victim earth station and abnormal interference avoidance process.
- Step 4 in order to avoid the situation where the interfering earth station is always uplinking with the satellite and thus cannot receive the RS-1 sent by the interfered earth station, the interfered earth station can send RS-1 only after the satellite gateway is configured. Otherwise, if the waiting time window is exceeded, the interference avoidance strategy is abandoned and other methods are used.
- the satellite gateway participates in the initial decision configuration according to the prior information, and the satellite gateway does not participate in the subsequent interference avoidance process after the initial configuration, for example:
- the satellite gateway decides and configures the timing of the interfered earth station and the interfering earth station to send and monitor RS-1 or RS-2 signals based on prior information;
- the earth station starts detecting interference only after it is connected to the satellite. To save power, it does not detect interference when no connection is established.
- the interfering earth station needs to receive RS-1 to know that it is interfering, so the interfered earth station cannot send RS-1 spontaneously, but needs to report to the satellite gateway first.
- the satellite gateway is responsible for ensuring that the interfering earth station has a downlink time slot to receive RS-1.
- the satellite gateway After the satellite gateway is configured for the victim earth station and the interfering earth station, it will no longer participate in the subsequent interference avoidance process.
- the victim earth station and the interfering earth station will perform adaptive interference avoidance based on air interface signal transmission.

Description
本公开涉及通信技术领域,尤其涉及一种远程干扰管理(Remote Interference Mitigation,RIM)方法、设备、装置、系统及存储介质。
在卫星通信系统中,一般采用频分双工(Frequency Division Duplex,FDD)模式。随着卫星直连业务(Direct to Satellite Service,D2SS)需求的不断增加,时分双工(Time Division Duplex,TDD)模式的应用有望缓解卫星通信系统中频率资源短缺的问题,并促进星地融合。若在卫星通信系统中大规模应用TDD模式,可能出现远程干扰(Remote Interference,RI)问题。

本公开实施例中,3GPP对FDD模式的卫星通信系统进行标准化,TDD模式的卫星通信系统有待进一步研究。其中,TDD模式卫星通信可以包括以下特点:在天线结构上,发射机和接收机共用一组天线,可简化卫星或终端结构;在频率分配上,支持卫星与地面移动通信兼容,可复用地面产业链;在传输时延上,较FDD模式时延大,上下行链路间需要保护间隔,可能引起资源浪费;在调度时序上,上下行时隙不连续,对调度时序要求严格;在干扰管理上,存在上下行链路间的干扰。基于TDD模式卫星通信的特点,TDD模式若在卫星通信系统中大规模应用,可能出现远程干扰问题。
本公开实施例中,RI是由空气对流层波导引起的干扰。
参考图1b所示,在地面通信系统中,TDD模式的基站下行链路传输功率通常远高于上行链路传输功率,在某些大气条件下,空气分层会使对流层形成波导,下行链路传输信号可以进入对流层波导以较低传播损耗传播数百公里,并对远处基站(如图中下侧基站)的上行链路产生干扰。RI可以持续几分钟到数小时,传播距离甚至可以超过300km,对TDD移动通信系统产生长时间的大面积干扰。其中,图中D表示下行符号,U表示上行符号,GP表示保护间隔。
参考图1c所示,在TDD模式的卫星通信系统中,地球站上行信号可能对其它地球站下行信号产生RI。例如,地球站A与卫星进行上行传输时,地球站A的上行信号进入到对流层波导,经对流层波导传输至几百公里外的地球站V处,地球站V正与卫星进行下行传输,此时它不仅接收到了卫星的下行信号,同时还接收到了远处地球站A的上行信号,引起对卫星下行链路的RI。
参考图1d所示的铱星帧结构为例,假设卫星为铱星V表示受扰地球站,A1~AN表示N个不同的施扰地球站,由于对流层波导产生的传输延迟(Transmission delay),不同的施扰地球站会对受扰地球站产生RI。其中,铱星是采用TDD模式的商业卫星系统。
在一些实施例中,TDD系统中存在RI可能由于多方面的原因。例如,在频率方面,大气波导效应发生的频率范围通常在0.3-30GHz,而地球站的信号频率与此范围有较大部分重合。在功率方面,城区微小区场景(Umi)中6GHz基站发射功率最大约为52dBm,而地球站发射功率高达几百甚至上千瓦,易产生干扰。在天线指向方面,天线指向高空且地势相对空旷的区域容易产生远程干扰,例如无人机场景中基站波束上仰会增加地面移动通信系统远程干扰的可能性;地球站波束指向天空,仰角较低的波束同样容易形成远程干扰。
本公开实施例中,地面通信系统中的RIM架构包括集中式架构和分布式架构。参考图1e所示的集中式架构(Framework-0),网元节点(OAM)发挥统一调度作用,OAM能够收集施扰地球站和受扰地球站的信息,产生并实施合适的干扰规避方案,其中,RIM中参考信号的传输与停止、干扰规避方案的产生均需要OAM负责,对OAM依赖程度较高。参考图1f所示的分布式架构(Framework-1),基于地球站之间空口信号传输实现干扰规避,结构较为简单,不依赖于OAM的协调。
对于TDD卫星通信系统而言,施扰和受扰的主体为处于用户角色的地球站,上述集中式架构和分布式架构均无法满足卫星通信对时延的要求。其中,集中式架构的干扰规避策略完全由OAM配置决定,此架构建设和调度复杂;卫星通信时延比地面大,完全依赖卫星调度在时间上难以满足高度动态的处理要求。分布式架构中受扰基站和施扰基站之间能够交互的信息有限,并且,在卫星通信中地球站无法自行完成基于空口信号传输的干扰规避。因此,对于卫星通信系统中可能存在的RI问题,需要提供有效的交互方法,以进行干扰规避。
图2a是根据本公开实施例提供的一种RIM方法的交互示意图。如图2a所示,本公开实施例的RIM方法,包括:
步骤S2101,第一网络设备101确定存在RI。
在一些实施例中,结合前述实施例的描述,第一网络设备101即受扰地球站,由于大气波导现象,其可能受到一个或多个第二网络设备103的远程干扰,第二网络设备103即施扰地球站或称远程基站。
在一些实施例中,第一网络设备101在检测到符合设定特征的干扰噪声时确定存在RI。
可选地,设定特征例如是在设定时段内干扰噪声呈现如图2b所示的倾斜特征。如图2b所示,当第一网络设备101接收到来自不同距离的多个第二网络设备103的累积上行信号,第一网络设备101的下行链路(DL)符号受到的干扰将出现倾斜现象。
可选地,图2c为地面网络中受扰基站(Victim)的干扰噪声(IOT)分布示意图,参考图2c所示,RI由不同距离的多个施扰基站(Aggressor1~Aggressor4)的累积信号引起,距离受扰基站越远的施扰基站,其下行链路信号传播的时间将越长,影响受扰基站的上行链路符号(UL symbol)就越多。结合图2c,在本公开实施例的卫星通信系统中,第一网络设备101受到的RI由不同距离的多个第二网络设备103的累计信号引起,距离第一网络设备101越远的第二网络设备103,影响第一网络设备101的下行链路符号(DL symbol)就越多。
在一些实施例中,第一网络设备101可以在连接到卫星网关102之后才开始检测是否存在干扰,为节省功耗,未与卫星网关102建立连接时可不检测。
步骤S2102,第一网络设备101向卫星网关102发送报告信息。
可选地,报告信息用于指示第一网络设备101受到远程干扰RI。
在一些实施例中,第一网络设备101发送报告信息,以指示其检测到“倾斜”的RI。在发送报告信息后,需要通过卫星网关102确定可能对第一网络设备101产生RI的第二网络设备102。
可选地,第一网络设备101在发送报告信息后,可以在预设的时段内等待。例如,在第一时间窗口T1内等待卫星网关下发配置信息。
在一些实施例中,卫星网关102接收该报告信息,并执行步骤S2103。
可选地,第二网络设备103收到第一RS时才会知晓自身在施扰,第一网络设备101不能自发的发送第一RS,需要先向卫星网关报告,卫星网关102需要保证第二网络设备103有下行时隙能收到第一RS。
步骤S2103,卫星网关102向至少一个第二网络设备103发送第二配置信息。
在一些实施例中,在卫星网关102收到报告信息后,需要确定可能产生干扰的一个或多个第二网络设备103。
可选地,至少一个第二网络设备103是卫星网关102根据第一网络设备101的位置确定的。
例如,卫星网关102根据先验信息或经验信息,在第一网络设备101所在位置附近一定范围内确定潜在施加干扰的第二网络设备103。
可选地,第二网络设备103出现远程干扰增加的现象时,可能认为自身受到干扰,而实际是接收到第一RS信号,因此由卫星网关102配置潜在施扰的第二网络设备103开始检测第一RS是有必要的。
可选地,卫星网关102可根据先验信息参与初始决策配置,如下发第一配置信息和第二配置信息,和配置或指示第一RS的发送和监听时机,和第二RS的发送和监听时机。在初始配置后,卫星网关102可不参与后续规避流程,第二网络设备103与第一网络设备101基于空口信号传输自适应进行RI规避如步骤S2107。
在一些实施例中,第二配置信息用于配置第一RS(或记为RS-1)和第二RS(或记为RS-2),并用于指示第二网络设备103开始监听第一RS。
可选地,第一RS用于指示第二网络设备103对第一网络设备101产生RI,并推算第一网络设备101有多少上行资源受到干扰。第二RS用于检测在第二网络设备执行RI规避行为之后第一网络设备是否还存在RI。
可选地,第二配置信息可以配置发送第一RS的时频资源或时频位置,和发送第二RS的时频资源或时频位置。其中,第一RS由第一网络设备101发送,第二RS由第二网络设备103发送。
在一些实施例中,第一RS的发送时域位置满足:在上行时域单元中,且包括上行时域单元与下行时域单元的边界之前的数个符号;和/或,第二RS的发送时域位置满足:在上行时域单元中,且包括上行时域单元与下行时域单元的边界之前的数个符号。
可选地,时域单元可以是时隙、毫秒或窗口等单元,本实施例以时域单元为时隙为例进行说明。
可选地,与地面通信系统的帧结构不同,结合图1d铱星的帧结构,TDD帧结构顺序为UL时隙、保护间隔和DL时隙。第一RS或第二RS传输的位置可以在UL传输边界之前的最后X个符号中。
可选地,X的值可以由协议定义。
可选地,用于RIM的第一RS或第二RS的配置可以满足以下至少一项:
(1)与已有RS存在区别:
与用于解调和测量的RS不同;
在资源配置和序列设计上与已有RS区分,以避免后向兼容性问题。
(2)时域模式配置:
定义RS传输的周期性,可在网络中半静态配置;
传输周期内可半静态配置多个RS传输时机,以区分RIM RS资源。
(3)传输位置:
RS的传输位置固定在UL传输边界之前的最后X个符号中。
(4)配置:
第一RS或第二RS需要在时间和序列上区分开,并分别配置;
多个第一RS配置共享相同的频率资源和序列;
多个第二RS配置共享相同的频率资源和序列。
(5)网络设备配置多个用于RIM的RS:
网络设备可以在配置的周期内进行多个RIM RS配置;
RIM RS传输周期是TDD DL/UL模式周期的倍数。
可选地,该第二配置信息适用于接收到该配置的第二网络设备103。
可选地,第二网络设备103接收该第二配置信息,并可执行步骤S2104。
步骤S2104,第二网络设备103根据第二配置信息监听第一RS。
可选地,收到第二配置信息的第二网络设备103监听或检测第一RS,而未收到第二配置信息的第二网络设备103则可以不检测第一RS。
可选地,第二网络设备103根据第二配置信息配置的第一RS的时频位置,在对应的时频位置监听或检测第二RS。
可选地,第二网络设备103接收到第二配置信息后再开始监听或检测第一RS。
在一些实施例中,在第二网络设备103开始监听第一RS时,第二网络设备103认为第一网络设备101接收到卫星网关102发送的第一配置信息;或者,
在第二网络设备103开始监听第一RS时,第一网络设备101接收到第一配置信息,其中第二网络设备103未对第一网络设备101产生RI;或者,
在第二网络设备103开始监听第一RS时,第一网络设备101未接收到第一配置信息或未开始发送第一RS;其中,第一配置信息用于配置第一参考信号RS和第二RS,并用于指示第一网络设备开始发送第一RS。
在一些实施例中,第二网络设备103在第二时间窗口T2内监听第一RS。
可选地,若第二网络设备103在T2内能接收到第一RS,表示该第二网络设备103对第一网络设备101产生RI,需要执行步骤S2107的规避行为。
可选地,若第二网络设备103在T2内都未接收到第一RS,或者超过预设的T2时第二网络设备103仍未监听或检测到第一RS,表示该第二网络设备103产生的RI已消除或者并未对第一网络设备101产生RI,第二网络设备103可停止对RS-1的监听或检测,并恢复原始配置。
步骤S2105,卫星网关102向第一网络设备101发送第一配置信息。
可选地,第一配置信息用于配置第一参考信号RS和第二RS,并用于指示第一网络设备101开始发送第一RS。
可选地,第一配置信息中第一RS或第二RS的配置可与第二配置信息相同,如发送第一RS的时频位置相同,或者发送第一RS的时频位置相同。
在一些实施例中,在第一网络设备101发送报告信息后,可以在第一时间窗口T1内监听第一配置信息。
可选地,若第一网络设备101的等待时间超过第一时间窗口T1时,未接收到第一配置信息,且此时RI还未消失,通信业务较紧急,则第一网络设备101可以停止等待,考虑切星等其他方案规避干扰。
可选地,第一网络设备101接收该第一配置信息,并可以执行步骤S2106。
步骤S2106,第一网络设备101根据第一配置信息,发送第一RS,并监听第二RS。
可选地,第一网络设备101基于第一配置信息,在合适的时频位置发送第一RS,并在合适的时频位置监听或检测第二RS。
可选地,第一网络设备101监听第二RS的时长可以满足预设的时长,如第一网络设备101在第三时间窗口T3内监听第二RS。
可选地,步骤S2105~S2106可能会在步骤S2104之后执行,即卫星网关102先为第二网络设备103配置开始监听第一RS,有利于保证第二网络设备103能够有DL时隙接受配置并且能够接收到第一网络设备101发送的第一RS。若先为第一网络设备101配置传输第一RS,则可能出现第一网络设备101发送第一RS但第二网络设备103尚未开始接收的情况,导致第一网络设备101功率浪费,使干扰规避流程异常。
可选地,为了避免第二网络设备103一直和卫星网关102进行上行传输从而收不到第一网络设备101发送的第一RS的情况,卫星网关102发送第一配置信息后,第一网络设备101才可以发送第一RS,否则超过等待时间窗口则放弃该干扰规避策略,采用其他方法。
步骤S2107,第二网络设备103在第二时间窗口T2内接收到第一RS,执行RI规避行为。
可选地,若第二网络设备103接收到第一RS,表示其对第一网络设备101存在干扰,需要自适应执行RI规避行为。
在一些实施例中,RI规避行为至少包括以下一项或多项:
降低发射功率;
增大上行传输时域单元与下行传输时域单元之间的保护间隔;
增大发射波束仰角。
可以理解的,上述RI规避行为仅作示意而非限定,还可以采用其他规避方案,本实施例对此不作限定。
步骤S2108,第二网络设备103根据第二配置信息,向第一网络设备101发送第二RS。
可选地,第二RS用于检测在第二网络设备103执行RI规避行为之后第一网络设备101是否还存在RI。
可选地,结合步骤S2106的实施方式,第一网络设备101在接收到第一配置信息后监听第二RS。
在一示例中,若第一网络设备101能够接收到第二RS,表示RI仍存在,第一网络设备101保持发送第一RS,即继续执行步骤S2106。
在另一示例中,若第一网络设备101未接收到第二RS,可能第二网络设备103的干扰已消除,也有可能存在其他实施干扰的地球站。
该示例中,若第一网络设备101在确定RI符合条件,如恢复到正常水平时,停止发送第一RS,即停止执行步骤S2106。可选地,RI符合条件或RI恢复到正常水平表示干扰已消除或干扰不再影响通信,RI符合条件或RI恢复到正常水平例如是第一网络设备101受到的RI不再出现图2b所示的倾斜特征。
或者,该示例中,若第一网络设备101在确定RI不符合条件,如未恢复到正常水平时,表示可能有新的未被配置的施扰地球站对受扰地球站进行干扰,向卫星网关102重新发送报告信息,即再次执行步骤S2102。可选地,RI不符合条件或未恢复到正常水平,例如是第一网络设备101受到的RI仍存在如图2b所示的倾斜特征。

1)地面远程干扰是由来自不同距离的多个远程基站的累积信号引起的,距离越远的基站,其下行链路信号传播的时间将越长,影响受扰基站的上行链路符号就越多,受扰基站的干扰噪声(IOT)分布如图2c所示;同理,TDD卫星通信系统中的受扰地球站也会受到来自不同距离的多个远程地球站的累积信号干扰。
2)当出现大气波导现象时,受扰基站的干扰噪声呈“倾斜”现象,如图2b所示。同理,当TDD受扰地球站收到来自不同距离的多个远程地球站的累积上行信号,其下行链路符号受到的干扰也将出现“倾斜”的现象。
Step 1:受扰地球站检测到“倾斜”的远程干扰后,向卫星网关报告,并开始在时间窗口T1内等待网关配置RS-1和RS-2信号。
Step 2:卫星网关根据先验信息,为受扰地球站附近一定范围内的潜在施扰地球站配置RS-1、RS-2信号和干扰规避流程,并通知其可以开始检测RS-1。
Step 3:施扰地球站根据卫星网关的配置开始检测RS-1,若超过预设的时间窗口T2仍没有检测到RS-1,说明该地球站当前并未对其他地球站产生干扰,则跳至Step8,停止对RS-1的检测,并恢复原始配置(original config)。
Step 4:卫星网关为受扰地球站配置RS-1、RS-2信号和干扰规避流程,通知受扰地球站可以开始RS-1传输和RS-2检测。
Step 5:受扰地球站启动RS-1传输和对施扰地球站RS-2的检测。
Step 6:在施扰地球站接收到RS-1后,施扰地球站启动远程干扰规避方案(如增大保护间隔、降低发射功率等);之后发送RS-2用于测试受扰地球站的远程干扰现象是否仍然存在。
Step 7-1:如果受扰地球站在Step 5中没有检测到RS-2;
1)若干扰恢复到正常水平,则表示成功规避干扰,受扰地球站停止RS-1传输;
2)若干扰未恢复到正常水平,表示可能有新的未被配置的施扰地球站对受扰地球站进行干扰,需要重新向卫星网关报告,返回Step1。
Step 7-2:如果受扰地球站在Step 5中仍能检测到RS-2,则说明仍然存在地球站的远程干扰,此时受扰地球站继续传输RS-1,返回Step 5。
Step 8-1:如果施扰地球站在Step 3的时间窗口T2内接收不到RS-1,表示远程干扰已消除,施扰地球站就停止对RS-1的检测,并恢复原始配置。
Step 8-2:如果施扰地球站在Step 3的时间窗口T2内仍能接收到RS-1,则表示它仍然在干扰其他地球站,就继续实施远程干扰规避方案,返回Step 6。
可选地,对于信令流程Step 1、Step 2和Step 4,有如下说明:
在Step 1中,RS-1用于告知施扰地球站其正在干扰受扰地球站,并推算受扰地球站有多少UL资源受到干扰;RS-2用于施扰地球站实行干扰缓解方案之后测试干扰是否还存在。若受扰地球站的等待时间超过预设的时间窗口T1,远程干扰现象还没有消失,且业务较紧急,则停止等待,考虑切星等其他方案规避干扰。
在Step 2中,需要先为施扰地球站配置并开始检测RS-1,有两方面考虑:
1)保证施扰基站能够有DL时隙接受配置并且能够接收到受扰地球站发送的RS-1;
2)若先为受扰地球站配置传输RS-1,则可能出现受扰地球站发送RS-1但施扰地球站还未开始接收的情况,导致受扰地球站功率浪费,使干扰规避流程异常。
在Step 4中,为了避免施扰地球站一直和卫星进行上行传输从而收不到受扰地球站发送的RS-1的情况,卫星网关配置后,受扰地球站才可以发送RS-1,否则超过等待时间窗口则放弃该干扰规避策略,采用其他方法。
可选地,本公开实施例的增强在于新增了Aggressor和Victim地球站与卫星Gateway间信令交互机制。Step1、2、4中RS的相关配置可复用现有协议,RIM RS传输位置的配置需注意:在地面TDD通信系统中,TD-LTE网络的帧结构顺序为DL时隙、保护间隔、UL时隙,基站传输RS的位置固定在DL传输边界之前的最后X个符号中;而在卫星TDD通信系统中,以铱星TDD帧结构为例,其TDD帧结构顺序为UL时隙、保护间隔、DL时隙,所以地球站传输RS的位置应在UL传输边界之前的最后X个符号中。
可选地,本公开实施例中由卫星网关根据先验信息参与初始决策配置,卫星网关初始配置后便不在参与后续干扰规避流程,例如:
1)在检测到远程干扰后,由卫星网关根据先验信息决策并配置受扰地球站和施扰地球站发出和监听RS-1或RS-2信号的时机;
在地球站连接到卫星之后才开始检测干扰,为节省功耗,未建立连接时不检测;
施扰地球站需要收到RS-1才能知道其正在施扰,所以受扰地球站不能自发的发送RS-1,需要先向卫星网关报告,卫星网关承担保证施扰地球站一定有下行时隙能收到RS-1的责任;
施扰地球站出现远程干扰增加的现象时,可能也认为自身是受扰地球站,而真实情况是收到了RS-1信号,所以由卫星网关配置哪些潜在施扰地球站开始检测RS-1是有必要的。
2)卫星网关为受扰地球站和施扰地球站配置后便不再参与后续干扰规避流程,由受扰地球站和施扰地球站基于空口信号传输进行自适应的干扰规避。
