Definitions
- This application relates to the field of communications, and specifically to a method and device for measurement reporting.
- the 5th generation (5G) mobile communication system uses high-frequency communication, that is, uses high-frequency (for example, a frequency band higher than 6 GHz) signals to transmit data.
- high-frequency communication uses high-frequency (for example, a frequency band higher than 6 GHz) signals to transmit data.
- One of the main problems of high-frequency communication is that the signal energy drops sharply with the transmission distance, resulting in a shorter signal transmission distance.
- analog beam technology has been proposed for high-frequency communication.
- the analog beam technology refers to the use of large-scale antenna arrays to concentrate the signal energy in a small range to form a signal similar to a beam, thereby increasing the transmission distance. This beam-like signal can be called an analog beam, or beam for short.
- the beam measurement process roughly includes the following process: the network device configures multiple measurement resources (resources for short) for the terminal device through the measurement configuration information, and each resource corresponds to a beam; the terminal device measures the resources configured by the network device to determine the resources (ie resources). The reference signal receiving power (RSRP) of the corresponding beam) is measured, and then several resources with the largest RSRP are selected, and the indexes of these resources and RSRP are reported to the network equipment; the network equipment reports from the terminal equipment Select one resource among several resources, and use the beam corresponding to the resource to send data.
- RSRP reference signal receiving power
- multi-user transmission that is, network equipment transmits data to multiple users through multiple beams in the same time slot. If beams with strong interference are used to transmit data, it will cause data transmission errors and reduce multi-user transmission. effectiveness. Therefore, in the multi-user transmission scenario, the problem of beam interference needs to be solved.
- network equipment judges the interference between beams based on RSRP. For example, the network device selects one of the largest RSRP resources reported by the terminal device as the channel resource, that is, uses the beam corresponding to the channel resource as the beam for data transmission, and treats the remaining resources as strong interference resources. In multi-user transmission , Avoid using these several RSRP largest resources at the same time.
- the several RSRP largest resources reported by the terminal device may not necessarily have strong interference with each other. Therefore, the network device cannot accurately know the interference situation between the beams.
- This application provides a method and device for measurement and reporting, which can enable network equipment to more accurately learn the interference resources of channel resources, so that the network equipment can perform reasonable beam interference management, thereby avoiding simultaneous use of multiple interference resources with strong mutual interference.
- the beam performs multi-user transmission.

- Channel resources refer to resources reported by the terminal equipment to the network equipment for data transmission. It should be understood that the network device may select one or more resources from the channel resources reported by the terminal to perform data transmission with the terminal device.
- the interference resource of channel resource A represents the same resource as the receiving beam of the channel resource A. In other words, if the receiving beam used by the terminal device when measuring a certain resource is different from the receiving beam of the channel resource A, the terminal device will not use the resource as the interference resource of the channel resource A.
- the receiving beam used by the terminal device to measure a resource is configured by the network device or can be independently selected by the terminal device.
- the terminal device can learn the receiving beam of each resource in the measurement resource configured by the network device according to the configuration of the network device or the autonomous algorithm of the terminal device.
- For a channel resource to be reported if the receiving beam of a resource in the measurement resource (denoted as resource 1) is the same as the receiving beam of the channel resource, then this resource 1 can be regarded as the interference resource of the channel resource; if the resource is measured If the receiving beam of one resource (denoted as resource 2) is different from the receiving beam of the channel resource, it is considered that resource 2 is not the interference resource of the channel resource.
- the terminal device may select M resources from the interference resource set of the channel resource A as the M interference resources of the channel resource A.
- the interference resource set of the channel resource A represents a set of resources in which the receiving beam and the receiving beam of the channel resource A are the same among the measurement resources configured by the network device.
- the network device when scheduling multiple resources including the channel resource, it can avoid interference or adjust the transmission modulation and coding scheme (MCS) of the interference paired beam.
- MCS transmission modulation and coding scheme
- the terminal device reports the interference resource of the channel resource to the network device, so that the network device can learn more accurate interference between beams, so that in multi-user transmission, it can effectively avoid the use of strong Beams that interfere with each other are used for transmission, which can improve the efficiency of multi-user transmission.

Reporting the index of weak interference can inform the network device which resource corresponding beams cause little interference to the beam corresponding to the channel resource. When performing multi-user transmission, these beams should be used as much as possible to pair with the beam corresponding to the channel resource for transmission.

Description
本申请要求于2019年01月31日提交中国专利局、申请号为201910100189.4、申请名称为“测量上报的方法与装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信领域,具体涉及一种测量上报的方法与装置。
第五代移动通信系统(5th generation,5G)采用高频通信,即采用高频段(例如高于6GHz的频段)信号传输数据。高频通信的一个主要问题是信号能量随传输距离急剧下降,导致信号传输距离较短。为了克服这个问题,模拟波束技术被提出来用于高频通信。模拟波束技术指的是,通过大规模天线阵列将信号能量集中在一个较小的范围内,形成一个类似于光束一样的信号,从而提高传输距离。这个类似于光束一样的信号可以称为模拟波束,简称波束。
网络设备可以生成不同的波束,不同的波束指向不同的传输方向。具体采用哪个波束来进行传输是通过波束测量过程来确定的。波束测量过程大致包括如下流程:网络设备通过测量配置信息为终端设备配置多个测量资源(简称资源),每个资源对应一个波束;终端设备通过测量网络设备配置的资源,对各资源(即资源对应的波束)的参考信号接收功率(reference signal receiving power,RSRP)进行测量,然后选择若干个RSRP最大的资源,将这几个资源的索引与RSRP上报给网络设备;网络设备从终端设备上报的若干个资源中选择一个资源,并采用该资源对应的波束发送数据。
在多用户传输中,即网络设备在同一时隙通过多个波束分别向多个用户传输数据,如果采用互相具有较强干扰的波束来进行传输数据,会导致数据传输错误,降低多用户传输的效率。因此,在多用户传输场景中,需要解决波束干扰的问题。
当前技术中,网络设备基于RSRP判断波束之间的干扰情况。例如,网络设备从终端设备上报的若干个RSRP最大的资源中选择一个作为信道资源,即把该信道资源对应的波束作为数据传输的波束,将其余资源视为强干扰资源,在多用户传输中,避免同时使用这若干个RSRP最大的资源。
但实际中,终端设备上报的若干个RSRP最大的资源不一定互相之间具有较强干扰,因此,网络设备无法准确获知波束之间的干扰情况。
因此,采用现有技术,在进行多用户传输时,由于网络设备无法获知波束之间的干扰情况,可能会采用具有较强相互干扰的波束来进行传输,导致数据传输错误,从而降低多用户传输的效率。
发明内容
本申请提供一种测量上报的方法与装置,可以使得网络设备较准确地获知信道资源的干扰资源,以便于网络设备进行合理的波束干扰管理,从而可以避免同时采用具有较强相互干扰的多个波束进行多用户传输。
第一方面,提供了一种测量上报的方法,所述方法包括:接收网络设备通过测量资源发送的测量信号;基于所述测量信号,确定要上报的N个信道资源以及所述N个信道资源中每一个信道资源的M个干扰资源,其中,M与N为正整数;向所述网络设备上报测量结果,所述测量结果中包括所述N个信道资源的索引,以及所述N个信道资源中每一个信道资源的M个干扰资源的索引。
信道资源表示终端设备上报给网络设备的、用于数据传输的资源。应理解,网络设备可以从终端上报的信道资源中选择一个或多个资源来与该终端设备进行数据传输。
以N个信道资源中的一个信道资源(记为信道资源A)为例,信道资源A的干扰资源表示接收波束与该信道资源A的接收波束相同的资源。换句话说,如果终端设备测量某个资源时所采用的接收波束与信道资源A的接收波束不相同,则终端设备不会将该资源作为信道资源A的干扰资源。
应理解,终端设备测量一个资源采用什么接收波束是网络设备配置的,或者可以终端设备自主选择的。换言之,终端设备可以根据网络设备的配置或者终端设备自主算法,可以获知网络设备配置的测量资源中各个资源的接收波束。针对要上报的一个信道资源,如果测量资源中的一个资源(记为资源1)的接收波束与该信道资源的接收波束相同,则这个资源1可以视作该信道资源的干扰资源;如果测量资源中的一个资源(记为资源2)的接收波束与该信道资源的接收波束不同,则认为资源2不是该信道资源的干扰资源。
例如,针对一个信道资源A,终端设备可以该信道资源A的干扰资源集合中选择M个资源作为信道资源A的M个干扰资源。信道资源A的干扰资源集合表示,网络设备配置的测量资源中接收波束与信道资源A的接收波束相同的资源的集合。
应理解,网络设备获取信道资源的干扰资源之后,在调度包括该信道资源的多个资源时,可以通过干扰规避,或者调整干扰配对波束的传输调制与编码策略(modulation and coding scheme,MCS),以降低同时调度的多个资源之间的相互干扰对数据传输的影响,从而可以提高数据传输的吞吐量。
因此,本申请提供的方案,通过终端设备向网络设备上报信道资源的干扰资源,使得网络设备可以获知较为准确的波束之间的干扰情况,从而在多用户传输中,可以有效避免采用具有较强相互干扰的波束来进行传输,进而可以提高多用户传输的效率。
结合第一方面,在第一方面的一种可能的实现方式中,终端设备上报的信道资源的干扰资源可以均为强干扰资源,或者均为弱干扰资源。
强干扰资源是指会对信道资源造成的干扰很强的资源。上报强干扰资源的索引可以通知网络设备哪些资源对应的波束会对信道资源对应的波束造成强烈干扰,在进行多用户传输时,应该尽量规避这些干扰。
弱干扰资源是指对信道资源造成的干扰很小的资源。上报弱干扰的索引可以通知网络设备哪些资源对应的波束对信道资源对应的波束造成的干扰很小,在进行多用户传输时,应该尽量采用这些波束来与信道资源对应的波束进行配对传输。
可选地,在本实现方式中,终端设备向网络设备上报强干扰资源还是弱干扰资源,可以通过网络设备配置或协议规定。
结合第一方面,在第一方面的一种可能的实现方式中,所述方法还包括:接收所述网络设备下发的测量配置信息,所述测量配置信息中包括一个用于指示N的值的字段或参数;和/或,所述测量配置信息中包括一个用于指示M的值的字段或参数。

应理解,通过网络设备对N和/或M的配置,使得终端设备可以获知要上报的信道资源的数目,以及每个信道资源的干扰资源的数目。
可选地,N和M值除了可以由网络设备配置,还可以通过协议规定。
结合第一方面,在第一方面的一种可能的实现方式中,确定要上报的所述N个信道资源中每一个信道资源的M个干扰资源,包括:针对所述N个信道资源中的第一信道资源,将采用第一信道资源的接收波束接收的其它资源中的M个资源确定为第一信道资源的M个干扰资源。

候选信道资源表示网络资源下发的测量信号对应的测量资源中的一组用于选择信道资源的资源。候选干扰资源表示网络资源下发的测量信号对应的测量资源中的一组用于选择干扰资源的资源。
候选信道资源与候选干扰资源可以是不同组的资源,也可以是同一组的资源。例如,当把网络资源下发的测量信号对应的测量资源中的一个资源作为信道资源组时,可以把其它资源作为候选干扰资源。
结合第一方面,在第一方面的一种可能的实现方式中,所述测量结果中还包括所述N个信道资源中每一个信道资源分别在M个干扰资源的干扰下的信干噪比。
应理解,通过终端设备向网络设备上报信道资源在干扰资源的干扰下的信干噪比,可以使得网络设备获取更加充分的波束之间干扰的情况,有助于网络设备在多用户传输中避免同时使用互相强干扰的波束。
在测量结果包括信道资源的信干噪比的实现方式中,在该测量结果中可以采用多种方式表示该信干噪比。

下面将结合附图,对本申请中的技术方案进行描述。
除非另有定义,本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的,不是旨在于限制本申请。
本申请实施例可以应用于基于波束的多载波通信系统,例如,5G系统或新无线(new radio,NR)系统。
为便于理解本申请实施例,下面首先介绍本申请实施例涉及的一些术语。
1、波束
波束在NR协议中的体现可以是空域滤波器(spatial domain filter),或者称空间滤波器(spatial filter)或空间参数(spatial parameter)。用于发送信号的波束可以称为发送波束(transmission beam,Tx beam),可以称为空域发送滤波器(spatial domain transmission filter)或空间发射参数(spatial transmission parameter);用于接收信号的波束可以称为接收波束(reception beam,Rx beam),可以称为空域接收滤波器(spatial domain receive filter)或空间接收参数(spatial RX parameter)。
发送波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布,接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。
此外,波束可以是宽波束,或者窄波束,或者其它类型波束。形成波束的技术可以是波束赋形技术或者其它技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术或者混合数字/模拟波束赋形技术等。
波束一般和资源对应,例如进行波束测量时,网络设备通过不同的资源来测量不同的波束,终端设备反馈测得的资源质量,网络设备就知道对应的波束的质量。在数据传输时,波束信息也是通过其对应的资源来进行指示的。例如网络设备通过DCI中的TCI资源, 来指示终端设备PDSCH波束的信息。
可选地,具有相同或者类似的通信特征的多个波束可以视为一个波束。
一个波束内可以包括一个或多个天线端口,用于传输数据信道、控制信道和探测信号等。形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
在本申请实施例中,若未做出特别说明,波束是指网络设备的发送波束。
在波束测量中,网络设备的每一个波束对应一个资源,因此可以资源的索引来唯一标识该资源对应的波束。
2、资源
在波束测量中,可以通过资源的索引来唯一标识该资源对应的波束。
资源可以是上行信号资源,也可以是下行信号资源。
上行信号包括但不限于:探测参考信号(sounding reference signal,SRS)与解调参考信号(demodulation reference signal,DMRS)。
下行信号包括但不限于:信道状态信息参考信号(channel state information reference signal,CSI-RS)、小区专用参考信号(cell specific reference signal,CS-RS)、UE专用参考信号(user equipment specific reference signal,US-RS)、解调参考信号(demodulation reference signal,DMRS)以及同步信号/物理广播信道块(synchronization signal/physical broadcast channel block,SS/PBCH block)。其中,SS/PBCH block可以简称为同步信号块(synchronization signal block,SSB)。
资源可以通过无线资源控制(radio resource control,RRC)信令配置。
在配置结构上,一个资源是一个数据结构,包括其对应的上行/下行信号的相关参数,例如上行/下行信号的类型,承载上行/下行信号的资源粒,上行/下行信号的发送时间和周期,发送上行/下行信号所采用的端口数等。
每一个上行/下行信号的资源具有唯一的索引,以标识该上行/下行信号的资源。可以理解的是,资源的索引也可以称为资源的标识,本申请实施例对此不作任何限制。
3、波束测量
波束测量是R15协议中的一个测量流程,主要包括如下步骤一至步骤四。
步骤一、网络设备向终端设备发送测量配置信息。
网络设备可以通过无线资源控制(radio resource control,RRC)信令向终端发送测量配置信息。
测量配置信息主要包括两部分:资源配置信息和上报配置信息。
资源配置信息是指测量资源相关的信息。资源配置信息在协议里可以通过三级结构(资源配置(resourceConfig)-资源集(resourceSet)-资源(resource))进行配置。
网络设备可以为终端设备配置一个或多个资源配置,每个资源配置可以包括一个或多个资源集,每个资源集可以包括一个或多个资源。每个资源配置/资源集/资源中都可以包括一个自己的索引。此外,每个资源配置/资源集/资源中还可以包括一些其它参数,例如,资源的周期、资源对应的信号类型等。
上报配置信息是指测量结果上报相关的信息。上报配置信息在协议里可以通过上报配置(ReportConfig)进行配置。
网络设备可以为终端设备配置一个或多个上报配置,每个上报配置可以包括上报指 标、上报时间和周期以及上报格式等与测量结果上报相关的信息。此外,上报配置里还可以包括资源配置的索引,用于指示上报的结果是通过什么测量配置测得的。
为了更好地理解波束测量的架构,作为示例而非限定,下列是R15协议中资源配置和上报配置的具体格式。
步骤二、网络设备在资源配置信息所配置的资源对应的资源粒上发送下行信号,以使得终端设备通过测量下行信号,确定各资源的质量(即资源对应的波束的质量)。
步骤三、终端设备根据测量配置信息对下行信号进行测量。
步骤四、终端设备向网络设备发送波束测量报告。波束测量报告可以包括一个或多个资源的索引与质量等。
作为示例而非限定,表1是R15协议中波束测量报告采用的上报格式。
表1
其中,CRI(CSI-RS Index)字段和SSBRI(SSB Resource Index)字段用于指示要上报的资源索引。可以只上报CRI或SSBRI,或者二者都上报。
和
是CRI字段和SSBRI字段的长度。
RSRP字段与differential RSRP字段,用于指示资源的质量。资源的质量的上报采用差分上报准则。例如,在表1中,最好的资源的RSRP(如表1中的RSRP字段)采用7比特量化上报,而其它资源的RSRP(如表1中的differential RSRP字段)采用4比特量化上报。
波束测量报告可以承载在物理上行控制信道(physical uplink control channel,PUCCH)或物理上行共享信道中(physical uplink shared channel,PUSCH)。
本申请实施例的技术方案可以应用于第五代(5th Generation,5G)系统或新无线(New Radio,NR)等。
本申请实施例应用的通信系统中可以包括一个或多个网络设备,以及一个或多个终端设备。一个网络设备可以向一个或多个终端设备传输数据或控制信令。或者,多个网络设备也可以同时为一个终端设备传输数据或者控制信令。
作为示例而非限定,图1为本申请实施例应用的通信系统100的示意图。该通信系统100包括一个网络设备或110与多个终端设备120(如图1中所示的终端设备120a和终端设备120b)。网络设备110可以通过多个射频通道同时发送多个模拟波束来为多个终端设备传输数据。如图1所示,网络设备同时发送波束1和波束2,其中波束1用于为终端设备120a传输数据,波束2用于为终端设备120b传输数据。波束1可以称为终端设备120a的服务波束,波束2可以称为终端设备120b的服务波束。终端设备120a和终端设备120b可以属于同一个小区。
理想情况下,波束1的信号到达终端设备120a,波束2的信号到达终端设备120b。但是,有些情形下,网络设备同时发送的多个波束在终端设备侧会发生干扰。如图2所示,网络设备210同时发送波束3和波束4。波束3为网络设备210调度给终端设备220a的用于数据传输的波束,即波束3为终端设备220a的服务波束。波束4为网络设备210调度给终端设备220b的用于数据传输的波束,即波束4为终端设备220b的服务波束。信号传输过程中,由于信道环境,波束4在传输过程中发生反射,导致波束4(全部或部分)到达终端设备220a。这时,终端设备220a接收到自己的服务波束3,还接收到非服务波束4。对于终端设备220a而言,波束3是服务波束,波束4是干扰波束。在图2示例中,也可以认为波束4是波束3的干扰波束。
在图2中,如果终端设备210a和终端设备220b属于同一个小区,这种情况下,波束4对波束3的干扰可以称为小区内干扰。
如何减弱或避免网络设备同时下发的多个波束之间的干扰,是需要解决的技术问题。
如前文描述,现有技术中,网络设备通过判断终端设备上报的若干的资源的RSRP来确定互为干扰的波束。但实际中,终端设备上报的RSRP最大的多个资源之间不一定真的具有强干扰。例如,终端设备向网络设备上报RSRP最大的资源1和资源2,网络设备经资源1和资源2视为互相具有强干扰的资源。但是,终端设备测量资源1时采用的是接收波束1,在测量资源2时采用的接收波束2。实际中,终端设备采用接收波束1测量资源2时,资源2的RSRP较小。也就是说,当网络设备采用资源1对应的波束发送数据,终 端设备采用接收波束1进行接收时,其从资源2对应的波束收到的干扰信号能量是较弱的。因此,虽然终端设备测量资源2时,测得其具有较大的RSRP,但资源2并不是资源1的强干扰资源。
因此,现有技术中,网络设备无法获知较为准确的波束之间的干扰情况。
本申请提出一种测量上报的方法与装置,可以使得网络设备获知较为准确的波束之间的干扰情况,从而在进行多个用户传输时,可以避免采用具有较强相互干扰的波束来进行传输,可以提高多用户传输的效率。
本申请实施例中涉及的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。终端设备可以是移动站(Mobile Station,MS)、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant,PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(machine type communication,MTC)终端等。
本申请实施例中涉及的网络设备是一种部署在无线接入网中为终端设备提供无线通信功能的装置。网络设备可以包括各种形式的宏基站,微基站(也称为小站),中继站,接入点或传输接收节点(transmission and reception point,TRP)等。网络设备可以是5G网络中的基站设备或者未来演进的PLMN网络中的网络设备等。
图3为本申请实施例的测量上报的方法300的示意性流程图。该方法300包括如下步骤。
310,网络设备通过测量资源向终端设备发送测量信号。相应地,终端设备接收网络设备通过测量资源发送的测量信号。
例如,网络设备可以根据资源配置信息(如前文描述),向终端设备发送资源配置信息所配置的测量资源所对应的测量信号。例如,该测量信号为CSI-RS或SSB。
本申请对资源配置的方式不作限定。
320,终端设备基于测量信号,确定要上报的N个信道资源以及N个信道资源中每一个信道资源的M个干扰资源,其中,M与N为正整数。
例如,终端设备根据测量配置信息,测量相应的测量信号,根据测量的结果选择要上报的N个信道资源以及N个信道资源中每个信道资源的M个干扰资源。
信道资源表示终端设备上报给网络设备的、用于数据传输的资源。应理解,网络设备可以从终端上报的信道资源中选择一个或多个资源来与该终端设备进行数据传输。
以N个信道资源中的一个信道资源(记为信道资源A)为例,信道资源A的干扰资源表示接收波束与该信道资源A的接收波束相同的资源。换句话说,如果终端设备测量某个资源时所采用的接收波束与信道资源A的接收波束不相同,则终端设备不会将该资源作为信道资源A的干扰资源。
应理解,终端设备测量一个资源采用什么接收波束是网络设备配置的,或者可以终端设备自主选择的。换言之,终端设备可以根据网络设备的配置或者终端设备自主算法,可以获知网络设备配置的测量资源中各个资源的接收波束。针对要上报的一个信道资源,如果测量资源中的一个资源(记为资源1)的接收波束与该信道资源的接收波束相同,则这个资源1可以视作该信道资源的干扰资源;如果测量资源中的一个资源(记为资源2)的 接收波束与该信道资源的接收波束不同,则认为资源2不是该信道资源的干扰资源。
例如,针对一个信道资源A,终端设备可以该信道资源A的干扰资源集合中选择M个资源作为信道资源A的M个干扰资源。信道资源A的干扰资源集合表示,网络设备配置的测量资源中接收波束与信道资源A的接收波束相同的资源的集合。
下文将详细描述,终端设备确定N与M的值的方式,以及终端设备确定要上报的N个信道资源与每个信道资源的M个干扰资源的方式。
330,终端设备向网络设备上报测量结果,测量结果中包括N个信道资源的索引,以及N个信道资源中每一个信道资源的M个干扰资源的索引。
本文提及的资源的索引表示可以标识该资源的信息。
应理解,网络设备接收到终端设备上报的测量结果后,可以获知N个信道资源中每个信道资源的干扰资源,因此,网络设备可以获知较为准确的波束之间的干扰情况,从而在多用户传输中,网络设备可以有效避免采用具有较强相互干扰的波束来进行传输,进而可以提高多用户传输的效率。
例如,网络设备获取信道资源的干扰资源之后,在调度包括该信道资源的多个资源时,可以通过干扰规避,或者调整干扰配对波束的传输调制与编码策略(modulation and coding scheme,MCS),以降低同时调度的多个资源之间的相互干扰对数据传输的影响,从而可以提高数据传输的吞吐量。
作为示例,如图3所示,该方法300还可以包括步骤340和步骤350。
340,网络设备从N个信道资源中确定用于向终端设备发送下行信号的第一资源,并根据测量结果,确定用于向其它终端设备(可记为第二终端设备)发送下行信号的第二资源。
例如,第二资源与第一资源不互为强干扰资源。
假设终端设备上报的干扰资源表示干扰最强的干扰资源,则所述第二资源不是所述第一资源的M个干扰资源中的任一个或多个资源。
假设终端设备上报的干扰资源表示干扰最弱的干扰资源,则所述第二资源可以是所述第一资源的M个干扰资源中的任一个或多个资源。
应理解,网络设备可以将N个信道资源中的一个或多个信道资源作为向第一终端设备设备发送下行信号的第一资源。
350,网络设备使用第一资源向该终端设备发送第一下行信号,使用第二资源向其它终端设备发送第二下行信号。
因此,本申请提供的方案,通过终端设备向网络设备上报信道资源的干扰资源,使得网络设备可以获知较为准确的波束之间的干扰情况,从而在多用户传输中,可以有效避免采用具有较强相互干扰的波束来进行传输,进而可以提高多用户传输的效率。
可选地,在一些实施例中,该方法300还包括:网络设备向终端设备下发测量配置信息,该测量配置信息包括测量资源的相关信息以及测量结果上报的相关信息。
例如,测量资源的相关信息包括测量资源的索引、周期或类型等;测量结果上报的相关信息包括测量结果上报的周期或上报数据量等。
可选地,终端设备上报的信道资源的干扰资源可以均为强干扰资源,或者均为弱干扰资源。强干扰资源是指会对信道资源造成的干扰很强的资源。弱干扰资源是指对信道资源 造成的干扰很小的资源。终端设备向网络设备上报强干扰资源还是弱干扰资源,可以由标准协议规定也可以由网络设备指定。
例如,标准协议规定终端设备上报的每一个信道资源的M个干扰资源为该信道资源的所有的干扰资源中对本信道资源干扰最大的M个干扰资源。在该种情况下,网络设备知道哪些资源对应的波束会对信道资源对应的波束造成强烈干扰,在进行多用户传输时,当采用所述信道资源为第一终端设备发送下行信息时,应该尽量规避采用这些强干扰的资源为其他终端设备发送下行信息。
作为示例,资源2对于资源1是强干扰,那么网络设备在采用资源1对应的波束为终端设备1传输数据时,则不能同时采用资源2对应的波束为其它终端设备传输数据,否则会对终端设备1造成强干扰。
再例如,标准协议规定终端设备上报的每一个信道资源的M个干扰资源为该信道资源的所有的干扰资源中对本信道资源干扰最小的M个干扰资源。网络设备知道哪些资源对应的波束会对信道资源对应的波束造成强烈干扰,在进行多用户传输时,当采用所述信道资源为第一终端设备发送下行信息时,应该尽量采用这些弱干扰的资源为其他终端设备发送下行信息。
作为示例,资源2对于资源1是弱干扰,那么网络设备在采用资源1对应的波束为终端设备1传输数据时,尽可能的采用资源2对应的波束为其它终端设备传输数据。
再例如,通过网络设备下发指示信息来指示终端设备向网络设备上报的干扰资源是强干扰还是弱干扰。例如,网络设备向终端设备下发测量配置信息,该测量配置信息中包括指示干扰类型的信息,该干扰类型为强干扰或弱干扰。
如果网络设备配置的干扰类型为强干扰,则终端设备向网络设备上报N个信道资源中每个信道资源的M个强干扰资源。如果网络设备配置的干扰类型为弱干扰,则终端设备向网络设备上报N个信道资源中每个信道资源的M个弱干扰资源。
应理解,通过终端设备向网络设备上报信道资源的强干扰资源或弱干扰资源,有助于获知较为准确的波束之间的干扰情况,从而在多用户传输中,可以有效避免采用具有较强相互干扰的波束来进行传输,进而可以提高多用户传输的效率。
终端设备可以通过如下任一种方式来确定要上报的信道资源的数目N,以及要上报的每个信道资源的干扰资源的数目M:
方式1):根据测量配置信息确定N与M的值。
可选地,在一些实施例中,该方法300还包括:网络设备向终端设备下发测量配置信息,该测量配置信息中包括一个用于指示N的值的字段或参数,还包括一个用于指示M的值的字段或参数;终端设备根据该测量配置信息,确定N与M的值。
方式2):根据测量配置信息确定N的值,采用协议规定的值确定M的值。
可选地,在一些实施例中,该方法300还包括:网络设备向终端设备下发测量配置信息,该测量配置信息中包括一个用于指示N的值的字段或参数;终端设备根据该测量配置信息确定N的值,根据协议规定的值确定M的值。
作为一个示例,在N的值是网络设备通过测量配置信息配置给终端设备的实施例中,N的值可以通过参数nrofReportedRS(如前文描述)来进行配置。
应理解,在现有R15协议中,参数nrofReportedRS是用于配置终端设备要上报的资源 索引数。由于现有R15协议中没有区分信道资源和干扰资源,因此可以理解为,参数nrofReportedRS表示的是要上报的资源的总数。在本申请中,对参数nrofReportedRS的功能进行如下调整,使其在一些情况下可以用于指示N的值:
当终端设备只上报参考信号接收功率(RSRP)时(例如,参数reportQuantity被配置成ssb-Index-RSRP或cri-RSRP时),参数nrofReportedRS用于指示终端设备要上报的资源的数目(也可称为要上报的资源的索引的数目(CSI-RS Index,CRI))。这种情形与现有R15协议相同。
当终端设备需要上报信干噪比(SINR)时(例如,参数reportQuantity被配置成ssb-Index-L1-SINR或cri-L1-SINR时),参数nrofReportedRS用于指示终端设备要上报的信道资源的数目N(或称为要上报的信道资源的索引的数目)。
在N的值通过参数nrofReportedRS配置的情况下,M的值也可以通过测量配置信息配置,也可以通过协议规定。
方式3):根据测量配置信息确定M的值,采用协议规定的值确定N的值。
可选地,在一些实施例中,该方法300还包括:网络设备向终端设备下发测量配置信息,该测量配置信息中包括一个用于指示M的值的字段或参数;终端设备根据该测量配置信息确定M的值,根据协议规定的值确定N的值。
方式4):采用协议规定的值确定M和N的值。
即终端设备根据协议规定的值,确定M和N的值。
方式5):通过隐式的方式确定M和N的值。
可选地,在一些实施例中,该方法300还包括:网络设备向终端设备下发测量配置信息,测量配置信息用于指示需要上报的资源的总数X;终端设备根据预设规则与X的值,确定N和M的值。
该测量配置信息指示的需要上报的资源的总数X,指的是,终端设备向网络设备上报的测量结果中包含的资源的总数,即N个信道资源的数量与每个信道资源的M个干扰资源的数量的总和。
可选地,X可以采用现有R15协议中已有的参数进行配置,例如,X采用R15协议中的nrofReportedRS参数进行配置,也可以采用新的参数进行配置。本申请对此不作限定。
该预设规则表示可以使得终端设备根据X的值确定N与M的值的规则。
作为一个示例,该预设规则表示N的值为1,M的值等于X-1。在本例中,终端设备根据预设规则与X的值,确定N和M的值,包括:终端设备确定N的值为1,确定M的值为X-1。
例如,网络设备配置X等于4,则终端设备要上报1个信道资源,与该信道资源的3个干扰资源。
作为另一示例,该预设规则表示N的值为X/Q(X可以被Q整除),M的值为(X-N)/N,其中Q为大于1的整数。例如,Q等于2、3、4或5等。在本例中,终端设备根据预设规则与X的值,确定N和M的值,包括:终端设备确定N的值为X/Q,M的值为(X-N)/N。应理解,在本实施例中,X的值可以被Q整除。
例如,Q等于2,该预设规则可以表述为,N的值为X的一半(X为偶数),M的值为1。在本例中,终端设备根据预设规则与X的值,确定N和M的值,包括:终端设备 确定N的值为X/2,M的值为1。
上文罗列出若干个该预设规则的示例,为了不赘述,不再枚举。应理解,终端设备根据网络设备配置的需要上报的资源的总数X以及预设规则,确定出N和M的值的方案均落入本申请保护范围。
下文将描述步骤320中,终端设备基于网络设备下发的测量信号,确定要上报的N个信道资源,以及确定每个信道资源的M个干扰资源的方案。
在本申请中,可以采用多种方式确定要上报的N个信道资源。
第一种确定N个信道资源的方式:通过资源的参考信号接收功率(RSRP)选择N个信道资源。例如,将测量信号中参考信号接收功率(RSRP)最大的N个测量信号对应的资源确定为N个信道资源。
第二种确定N个信道资源的方式:通过资源的信干噪比选择N个信道资源。例如,将测量信号中信干噪比最大的N个测量信号对应的资源确定为N个信道资源。
信干噪比指的是,信号与干扰加噪声比(signal to interference plus noise ratio,SINR)。为了描述的简洁,下文中采用SINR表示信干噪比。
需要说明的是,采用SINR表示信干噪比,仅为示例而非限定。还可以采用其它表示方式,例如采用下列任一种来表示信干噪比:层1信干噪比(L1-SINR),信道状态信息信干噪比(CSI-SINR),同步信号块信干噪比(SSB-SINR),层1信道状态信息信干噪比(L1-CSI-SINR),层1同步信号块信干噪比(L1-SSB-SINR)。
SINR可以表达信道资源在一定干扰资源的干扰下能够达到的性能。
以一个信道资源A为例,作为示例,根据如下公式计算信道资源A的SINR:
SINR=信道资源能量/(干扰资源能量+其它能量) 式(1)
其中,公式(1)中的信道资源能量表示,在信道资源A上测得的信号能量。例如,信道资源能量等于承载信道测量信号的资源粒上的信号能量的线性平均值。这里的信道测量信号表示信道资源A对应的测量信号,例如,可以是非零功率信道状态信息参考信号(non-zero power channel state information-reference signal,NZP-CSI-RS)、SSB信号或其它信号。
公式(1)中的干扰资源能量表示,在信道资源A的干扰资源上测得的干扰能量,其中,信道资源A的干扰资源指的是,在用于接收信道资源A的接收波束上接收到的其它资源。例如,干扰资源能量等于承载干扰测量信号的资源粒上的信号能量的线性平均值。这里的干扰测量信号表示干扰资源对应的测量信号,可以是NZP-CSI-RS、SSB信号或其它信号。
可选地,公式(1)中的干扰资源能量可以是信道资源A的一个干扰资源上的干扰能量。
可选地,公式(1)中的干扰资源能量可以是信道资源A的多个干扰资源上的干扰能量之和。
例如,公式(1)中的干扰资源能量等于网络设备配置的所有干扰资源的干扰能量之和。
再例如,公式(1)中的干扰资源能量等于终端设备根据网络设备的配置所选择的所有干扰资源的干扰能量之和。
再例如,公式(1)中的干扰资源能量等于终端设备要上报的信道资源A的所有干扰资源的干扰能量之和。
公式(1)中的其它能量可以是承载信道测量信号的资源粒上的干扰能量的线性平均值。例如资源粒上的总能量减去信道测量信号的能量,剩余的能量等于其他能量。其它能量也可以是专门配置的信道状态信息干扰测量(channel state information-interference measurement,CSI-IM)上测得的总能量。
第三种确定N个信道资源的方式:通过资源的RSRP与SINR选择N个信道资源。
例如,将测量信号中信干噪比最大的N1个测量信号对应的测量资源中参考信号接收功率最大的N个测量信号对应的资源确定为N个信道资源,N1为大于或等于N的整数。
换句话说,先通过RSRP确定一个信道资源范围,例如,这个信道资源范围为测量资源中RSRP最大的若干个资源,再从该信道资源范围中选出SINR最大的N个信道资源。
在本实施例中,可以采用公式(1)计算信道资源的信干噪比。
再例如,将测量信号中参考信号接收功率最大的N2个测量信号对应的测量资源中信干噪比最大的N个测量信号对应的资源确定为N个信道资源,N2为大于或等于N的整数。
换句话说,先通过SINR确定一个信道资源范围,例如,这个信道资源范围为测量资源中SINR最大的若干个资源,再从该信道资源范围中选出RSRP最大的N个信道资源。
在本实施例中,可以采用公式(1)计算信道资源的信干噪比。
需要说明的是,上文结合公式(1)描述计算信道资源的信干噪比的方式,仅为示例而非限定。实际应用中,还可以采用其它可行的方式计算信道资源的信干噪比。本申请对此不作限定。
为了便于理解与描述,下文以N个信道资源中的第一信道资源为例,描述确定每个信道资源的M个干扰资源的方案。下文对第一信道资源的相关描述可以适用于N个信道资源中的每个信道资源。
在步骤320中,确定要上报的N个信道资源中每一个信道资源的M个干扰资源,包括:针对N个信道资源中的第一信道资源,将采用第一信道资源的接收波束接收的其它资源中的M个资源确定为第一信道资源的M个干扰资源。
可以将采用第一信道资源的接收波束接收的其它资源中的随机的M个资源确定为第一信道资源的M个干扰资源。或者,可以将采用第一信道资源的接收波束接收的其它资源中满足一定条件的M个资源确定为第一信道资源的M个干扰资源。
可选地,在步骤320中,确定要上报的N个信道资源中每一个信道资源的M个干扰资源,包括:针对N个信道资源中的第一信道资源,将采用第一信道资源的接收波束接收的参考信号接收功率最大或最小的M个其它资源确定为第一信道资源的M个干扰资源。
应理解,将参考信号接收功率最大的M个资源确定为第一信道资源的M个干扰资源,可以对应于上文描述的干扰类型为强干扰的方案。将参考信号接收功率最小的M个资源确定为第一信道资源的M个干扰资源,可以对应于上文描述的干扰类型为弱干扰的方案。
可选地,在步骤320中,确定要上报的N个信道资源中每一个信道资源的M个干扰资源,包括:针对N个信道资源中的第一信道资源,计算第一信道资源分别在采用第一信道资源的接收波束接收的其它每个资源的干扰下的信干噪比;在所计算的信干噪比中,将最大或最小的M个信干噪比对应的M个资源确定为第一信道资源的M个干扰资源。
例如,可以采用如下公式计算第一信道资源在干扰资源1的干扰下的信干噪比SINR1:
SINR=信道资源能量/(干扰资源能量1+其它能量) 式(2)
其中,公式(2)中的信道资源能量表示,在第一信道资源上测得的信号能量。例如,信道资源能量等于承载信道测量信号的资源粒上的信号能量的线性平均值。这里的信道测量信号表示第一信道资源对应的测量信号,例如,可以是NZP-CSI-RS、SSB信号或其它信号。
公式(2)中的干扰资源能量表示,在信道资源A的干扰资源1上测得的干扰能量。信道资源A的干扰资源1指的是,在用于接收信道资源A的接收波束上接收的一个其它资源。例如,干扰资源能量等于承载干扰测量信号的资源粒上的信号能量的线性平均值。这里的干扰测量信号表示干扰资源1对应的测量信号,可以是NZP-CSI-RS、SSB信号或其它信号。
可以理解到,公式(2)中的干扰资源能量与公式(1)中的干扰资源能量不能混为一谈。
公式(2)中的其它能量可以是承载信道测量信号的资源粒上的干扰能量的线性平均值。例如资源粒上的总能量减去信道测量信号的能量,剩余的能量等于其他能量。其它能量也可以是专门配置的CSI-IM上测得的总能量。
还需要说明的是,上文结合公式(2)描述第一信道资源在干扰资源1的干扰下的信干噪比SINR1的方式,仅为示例而非限定。实际应用中,还可以采用其它可行的方式计算信道资源在某一干扰资源的干扰下的信干噪比。本申请对此不作限定。
作为示例,终端设备先根据网络设备的测量配置信息,确定采用第一信道资源的接收波束接收的多个其它资源;然后,按照公式(2),计算第一信道资源分别在这多个其它资源中的每个资源的干扰下的信干噪比;最后从这多个信干噪比中选择出最大或最小的M个信干噪比作为第一信道资源的M个干扰资源。
例如,假设M等于2,对于信道资源1,选择信道资源1的2个干扰资源的流程包括:1)确定信道资源1的干扰资源集合{3,4,5,6},即终端设备测量资源{3,4,5,6}采用的接收波束与信道资源1的接收波束相同;2)分别将资源{3,4,5,6}作为干扰,计算信道资源1的SINR:SINR1_3,SINR1_4,SINR1_5和SINR1_6;3)在干扰资源集合{3,4,5,6}中选择2个最小SINR所对应的资源作为信道资源1的2个干扰资源,例如,如果SINR1_3和SINR1_4的SINR最小,则选择资源3和4作为信道资源1的2个干扰资源。
应理解,在本例中,将M个最小的信干噪比所对应的资源确定为信道资源的M个干扰资源,对应于上文描述的干扰类型为强干扰的方案。
再例如,假设M等于2,对于信道资源1,选择信道资源1的2个干扰资源的流程包括:1)确定信道资源1的干扰资源集合{3,4,5,6},即终端设备测量资源{3,4,5,6}采用的接收波束与信道资源1的接收波束相同;2)分别将资源{3,4,5,6}作为干扰,计算信道资源1的SINR:SINR1_3,SINR1_4,SINR1_5和SINR1_6;3)在干扰资源集合{3,4,5,6}中选择2个最大SINR所对应的资源作为信道资源1的2个干扰资源,例如,如果SINR1_5和SINR1_6的SINR最大,则选择资源5和6作为信道资源1的2个干扰资源。
应理解,在本例中,将M个最大的信干噪比所对应的资源确定为信道资源的M个干 扰资源,对应于上文描述的干扰类型为弱干扰的方案。
还应理解,也可以在对第一信道资源造成干扰的资源中,随机选择M个资源确定为第一信道资源的M个干扰资源。
可选地,在一些实施例中,步骤320包括:终端设备在候选信道资源中确定N个信道资源,在候选干扰资源中确定每个信道资源的M个干扰资源。
候选信道资源表示网络资源下发的测量信号对应的测量资源中的一组用于选择信道资源的资源。候选干扰资源表示网络资源下发的测量信号对应的测量资源中的一组用于选择干扰资源的资源。
候选信道资源与候选干扰资源可以是不同组的资源,也可以是同一组的资源。例如,当把网络资源下发的测量信号对应的测量资源中的一个资源作为信道资源组时,可以把其它资源作为候选干扰资源。
在本实施例中,网络设备可以通过下发测量配置信息来配置候选信道资源与候选干扰资源。本申请不对资源的配置方式做限定。作为示例,可以在资源配置(CSI-ResourceConfig)中配置候选信道资源与候选干扰资源,也可以在上报配置(CSI-ReportConfig)中配置候选信道资源与候选干扰资源。
可选地,在一些实施例中,终端设备向网络设备上报的测量结果中还可以包括N个信道资源中每一个信道资源分别在M个干扰资源的干扰下的信干噪比。

应理解,通过终端设备向网络设备上报信道资源在干扰资源的干扰下的信干噪比,可以使得网络设备获取更加充分的波束之间干扰的情况,有助于网络设备在多用户传输中避免同时使用具有较强相互干扰的波束。
在测量结果包括信道资源的信干噪比的实施例中,在该测量结果中可以采用多种方式表示该信干噪比。
可选地,在一些实施例中,终端设备向网络设备上报的测量结果中还可以包括N个信道资源中每一个信道资源分别在M个干扰资源的干扰下的信干噪比,对于N个信道资源中的第一信道资源分别在M个干扰资源的干扰下的M个信干噪比,采用如下方式表示:

作为示例,测量结果如表6所示。
表6
应理解,上述的信道资源的M个干扰资源的索引的排列方式,或者,信道资源的M个信干噪比的排列方式,仅为示例而非限定。实际应用中,在测量结果中,信道资源的M个干扰资源的索引的排列方式,或者,信道资源的M个信干噪比的排列方式还可以为除了前文描述的方式之外的其他可行的方式,本申请对此不作限定。还以第一信道资源为例, 第一信道资源的M个干扰资源的索引可以该M个干扰资源的测量顺序排列。
可选地,在一些实施例中,终端设备向网络设备上报的测量结果中还可以包括N个信道资源的参考信号接收功率(RSRP)。如表2、表3、表4、表5或表6中所示。

可选地,在上述一些实施例中,信干噪比(SINR)可以替换为信道质量标识(channel quality indicator,CQI)或RSRQ。
应理解,在上述一些实施例中,以N个信道资源中的第一信道资源为例进行描述,但这并不对本申请造成限定,本文中对第一信道资源的相关描述都可以适用于N个信道资源中的每个信道资源。
基于上述描述,本申请提供的方案,通过终端设备向网络设备上报信道资源的干扰资源,可以使得网络设备较准确地获知信道资源的干扰资源,以便于网络设备进行合理的波束干扰管理,从而可以避免同时采用具有较强相互干扰的多个波束进行多用户传输,进而提高多用户传输的性能与效率。

可选地,对于所述第一信道资源对应的K个干扰资源,除了上述定义的情形,还可以根据应用需求具有其它可行的定义方式。
上文提及两个资源(如上文中的干扰资源与信道资源)具有相同TCI配置,其中,两个资源具有相同TCI配置可以包括如下不同的情形。
可选地,两个资源具有相同TCI配置,指的是,这两个资源的TCI状态(TCI-state)索引相同。
可选地,两个资源具有相同TCI配置,指的是,这两个资源的TCI-state索引不同,但这两个资源包括的类型为typeD的QCL信息(QCL-info)对应的参考信号资源是相同的。
可选地,两个资源具有相同TCI配置,指的是,这两个资源的TCI-state索引不同,但这两个资源包括的所有QCL-info对应的参考信号资源都是相同的。
可选地,两个资源具有相同TCI配置,指的是,在这两个资源的TCI-state中具有相互包含关系。
例如资源2的TCI-state中包括的资源是资源1,也可以认为资源1和资源2具有相同的TCI配置。
上文中提及的具有相同的TCI配置可以用于下行资源与上行资源之间。
可选地,某个下行资源与某个上行资源具有相同的TCI配置可以指该下行资源的TCI-state中的参考资源与该上行资源的空间关系(spatial relation)(上行配置的不是TCI-state,而是spatial relation)中的参考资源相同。
可选地,某个下行资源与某个上行资源具有相同的TCI配置可以指该下行资源的TCI-state中的参考资源是该上行资源,或者指该上行资源的spatial relation中的参考资源是该下行资源。
上文中提及的具有相同的TCI配置还可以用于两个上行资源之间。
可选地,两个上行资源具有相同TCI配置可以指这两个上行资源具有相同的TCI-state或spatial-relation。
可选地,两个上行资源具有相同TCI配置可以指这两个上行资源的TCI-state或spatial-relation中包括的资源相同。

可选地,某个上行信道和某个上行资源具有相同TCI配置可以指该上行信道对应的SRS资源是该上行资源的TCI-state或spatial-relation中包括的资源。
440,终端设备向网络设备上报测量上报结果,该测量上报结果中包括一个或多个信道资源的测量结果,其中,一个信道资源的测量结果中包括该信道资源在其对应的干扰资源的干扰下的信干噪比。
以网络设备配置的一个信道资源(记为第一信道资源)为例,在步骤440中,终端设备向网络设备上报第一信道资源的测量结果,第一信道资源的测量结果包括第一信道资源分别在该第一信道资源对应的K个干扰资源的干扰下的信干噪比。其中,第一信道资源的K个信干噪比在第一信道资源的测量结果中的排序与K个干扰资源的索引相关,或者,与K个干扰资源的配置顺序相关。
终端设备上报信道资源的测量结果时,在上报格式中,同一信道资源的各个测量结果按照特定的顺序进行排序。
一种方法是按照各个干扰资源的索引的从大到小或从小到大的顺序进行排序。
例如,对于一个信道资源,其对应的干扰资源有4个,因此要上报4个SINR。这4个SINR在上报格式中按照对应的干扰资源的索引从大到小或从小到大的顺序排序。
另一种方法是按照各个干扰资源的配置顺序进行排序。
例如,对于一个信道资源,其对应的干扰资源有4个,因此要上报4个SINR。这4个SINR在上报格式中按照4个干扰资源的配置顺序进行排序。
按照特定的顺序进行上报是为了让网络设备确定各个测量结果是对应什么干扰资源,从而在不上报干扰资源的情况下知道干扰资源的信息。上述顺序可以是协议默认规定的,也可以是配置信息配置的。
以终端设备向网络设备上报第一信道资源的测量结果,该测量结果包括第一信道资源分别在K个干扰资源的干扰下的信干噪比为例,第一信道资源的K个信干噪比在第一信道资源的测量结果中的排序为:K个干扰资源的索引从大到小或从小到大的顺序;或K个干扰资源的配置顺序。
