一种信息上报的方法及装置 技术领域
本申请涉及通信技术领域，特别涉及一种信息上报的方法及装置。
背景技术
不同通信系统间的频谱共享是解决传统频谱使用方式带来的资源供需矛盾的有效授权，使得频谱资源被充分利用。例如，新无线电(new radio,NR)通信系统和长期演进(long term evolution,LTE)通信系统之间可以实现频谱共享，举例来说，NR和LTE都可以部署在2.1千兆赫(GHz)(频段(band)1)、1.8GHz(band 3)、800兆赫兹(MHz)(band 3)、2.6GHz(band 38)等频域资源上。
为了适应无线信道的变化，终端需要上报信道状态信息以供网络设备参考。在不同通信系统频谱共享的场景下，如何上报准确的信道状态信息，是亟需解决的问题。

2、网络设备。本申请实施例中网络设备是一种为终端设备提供无线通信功能的设备，也可称之为接入网设备、无线接入网(radio access network，RAN)设备等。其中，网络设备可以支持至少一种无线通信技术，例如LTE、NR、WCDMA等。示例的，网络设备包括但不限于：第五代移动通信系统(5th-generation，5G)中的下一代基站(generation nodeB， gNB)、演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved node B、或home node B，HNB)、基带单元(baseband unit，BBU)、收发点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)、和/或分布单元(distributed unit，DU)，或者网络设备可以为中继站、接入点、车载设备、终端设备、可穿戴设备以及未来移动通信中的网络设备或者未来演进的PLMN中的网络设备等。在一些实施例中，网络设备还可以为具有为终端设备提供无线通信功能的装置，例如芯片系统。示例的，芯片系统可以包括芯片，还可以包括其它分立器件。
3、终端设备与网络设备之间的通信。本申请实施例中终端设备和网络设备是通过通信接口进行通信的。例如，终端设备与网络设备之间的通信接口可以为通用的UE和网络之间的接口(universal UE to network interface，Uu空口)。当终端设备与网络设备之间的通信接口为Uu空口时，终端设备与网络设备之间的通信又可以称之为Uu空口通信。
4、时间单元。本申请实施例中时间单元可以指在时域上的一段时间。其中，本申请实施例中一个时间单元可以包括一个或多个基本时间单元。具体的，本申请实施例中通信例如旁链路通信或者Uu空口通信等是以基本时间单元为单位的。示例的，基本时间单元可以为无线帧(radio frame)、子帧(subframe)、时隙(slot)、微时隙(micro-slot)、迷你时隙(mini-slot)、或者符号等。例如，基本时间单元为子帧，一个时间单元可以包括一个或多个子帧；再例如，基本时间单元为符号，一个时间单元可以包括一个或多个符号。在一些实施例中，一个无线帧的时长可以是10毫秒(ms)。一个无线帧可以包括一个或多个子帧。比如，一个子帧的时长是1ms，则一个无线帧可以包括10个子帧。一个子帧可以包括一个或者多个时隙。其中，一个时隙的时长与子载波间隔的大小相关，不同大小的子载波间隔对应的时隙的时长是不同的。例如，子载波间隔为15kHz时，一个时隙的时长可以为1ms；子载波间隔为30kHz时，一个时隙的时长可以为0.5ms。示例的，本申请实施例中一个时隙可以包括一个或多个符号。比如，正常(normal)循环前缀(cyclic prefix，CP)下，一个时隙可以包括14个符号；扩展(extended)CP下，一个时隙可以包括12个符号。应理解，本申请实施例中符号又可以称之为时域符号，例如，符号可以为正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以为基于离散傅立叶变换扩展的正交频分复用(discrete fourier transform spread orthogonal frequency division multiplexing，DFT-s-OFDM)符号等。本申请实施例中微时隙(或迷你时隙)可以是比时隙更小的单位，一个微时隙可以包括一个或多个符号。比如一个微时隙(或迷你时隙)可以包括2个符号，4个符号或7个符号等。一个子帧可以包括一个或多个微时隙。一个时隙可以包括一个或多个微时隙(或迷你时隙)。
以子载波间隔为15kHz为例，本申请实施例中一个无线帧的结构可以如图1所示，无线帧的时长为10ms，包括10个子帧。每个子帧的时长为1ms。其中，每个子帧包括14个符号。例如，迷你时隙1包括符号0、符号1、符号2和符号3。再例如，迷你时隙2包括符号2和符号3。又例如，迷你时隙3包括符号7、符号8、符号9、符号10、符号11、和 符号12。
5、载波带宽部分。本申请实施例中的载波带宽部分可以简称为带宽部分(bandwidth part，BWP)，指的是载波上一段连续或非连续的频域资源，其中，这段连续或非连续的频域资源的带宽不超过终端设备的带宽能力，即BWP的带宽小于或等于终端设备支持的最大带宽。以BWP为载波上一段连续的频域资源为例，BWP可以是载波上一组连续的资源块(resource block，RB)，或者BWP是载波上一组连续的子载波，或者BWP是载波上一组连续的资源块组(resource block group，RBG)等。其中，一个RBG中包括至少一个RB，例如1个、2个、4个、6个或8个等，一个RB可以包括至少一个子载波，例如12个等。本申请实施例中终端设备与网络设备通信所使用的BWP，是网络设备配置的。对于一个终端设备来说，网络设备可以为终端设备在一个载波内配置一个或多个BWP。例如，如图2中的a所示，网络设备为终端设备在一个载波内配置了一个BWP。其中，BWP的带宽不超过终端设备的带宽能力，且BWP的带宽不大于载波带宽。再例如，如图2中的b所示，网络设备为终端设备在一个载波内配置了两个BWP，分别为BWP1和BWP2，其中，BWP1与BWP2存在重叠。又例如，如图2中的c所示，网络设备为终端设备在一个载波内配置了两个BWP，分别为BWP1和BWP2，其中BWP1和BWP2完全不重叠。需要说明的是，本申请实施例中网络设备为终端设备配置的BWP的个数不是无限制的。以NR的版本15(release 15，Rel-15)为例，网络设备为终端设备最多可以配置4个BWP。再例如，在频分双工(frequency division duplexing，FDD)的场景下，网络设备可以为终端设备的上、下行通信分别配置4个BWP。又例如，在时分双工(time division duplexing，TDD)的场景下，网络设备可以为终端设备的上、下行通信分别配置4个BWP，比如相同编号的BWP的中心频段对齐。此外，网络设备可以针对每个BWP，为终端设备配置系统参数。系统参数可以称之为配置参数(numerology)。示例的，系统参数可以包括子载波间隔、和/或CP类型等。其中，CP类型可以包括扩展CP和正常CP。本申请实施例中，不同的BWP对应的系统参数可以相同，也可以不同。以图2b为例，BWP1对应的系统参数和BWP2对应的系统参数可以相同，也可以不同。在另一些实施例中，网络设备针对每个BWP为终端设备的其它配置(例如BWP的位置)也不做限定。在实际通信中，终端设备当接入一个小区后，可以通过激活一个BWP，实现与网络设备之间的通信。通常，BWP是定义在一个给定的载波上的，即一个BWP位于一个载波内。当然，本申请并不限定其他对于BWP的定义，或其他BWP的激活方案等。
6、资源。本申请实施例中资源又可以被称为时频资源，用于进行各种信号或者数据的传输，可以通过资源栅格表示。图3所示为资源栅格的示例图。资源栅格中，资源元素(resource element，RE)是用于进行数据传输的资源单位，或者用于对待发送数据进行资源映射的资源单位。一个RE在时域对应一个符号，例如OFDM符号或者DFT-s-OFDM符号，频域对应一个子载波。一个RE可以用于映射一个复数符号，例如经过调制得到的复数符号，或者经过预编码得到的复数符号，本申请不做限制。在频域，在资源栅格中可以定义RB，在频域一个RB中可以包括正整数个子载波，例如12个。进一步地，RB的定义还可以扩展到时域，例如一个RB包括正整数子载波且时域包括正整数个符号，例如一个RB是频域包括12个子载波且时域包括7个符号的时频资源块。资源栅格中可以包括正整数个RB。在资源栅 格或者时频资源的时域可以定义时隙(slot)，如前所述一个时隙中可以包括正整数个符号，例如14个符号等。
7、频域资源。本申请实施例中频域资源指的是频域上的一段区域或者范围，是资源在频域维度的体现。例如，通过资源栅格表示时，在频域一个RB中可以包括正整数个子载波，比如12个。例如，该频域资源又可以称为载波、频域区域、频带、或者频段等等。又例如，频域资源具体地，可以为5MHz、10MHZ、50MHz等。
作为不同通信系统间频谱共享的举例，表1和表2分别示出了目前LTE通信系统和NR通信系统中的一些可用频段：
Figure PCTCN2020091931-appb-000001
表1：LTE的可用频段
Figure PCTCN2020091931-appb-000002
表2：NR在6GHz以下(sub6GHz)的可用频段
如表1和表2,在band 1、3、5等频段范围支持LTE通信系统与NR通信系统的频谱共享，也就是说在这些频段范围内LTE通信系统与NR通信系统可以重叠部署。
当NR通信系统和LTE通信系统共享频谱资源时，NR通信系统的载波既要充分利用LTE通信系统的载波未使用完的资源，又要避免对LTE通信系统的载波上传输的干扰。示例的，如图4所示，假设在如图所示的一段资源上，LTE通信系统的物理下行控制信道(physical downlink control channel,PDCCH)映射在了符号0和1上，则NR通信系统的物理下行共享信道(physical downlink shared channel,PDSCH)可以从符号2开始映射，如图4所示的灰色格子，其上即映射NR通信系统的PDSCH。这样避免了对LTE通信系统PDCCH的干扰。同时，为了避免对LTE通信系统中传输的小区特定参考信号(cell-specific reference signal,CRS)的干扰，NR通信系统还支持在映射LTE通信系统的CRS的资源上进行速率 匹配，也即，如图4所示，假设横条纹格子代表映射LTE通信系统的CRS的资源，那么在这些资源上，NR通信系统将不会映射NR通信系统的PDSCH。
对于不同的通信系统，为了使网络侧更好的获知无线信道的变化情况，需要终端设备将与信道质量相关的信息上报给通信系统中的网络设备。如此，网络设备便可以据此为终端设备选择更可靠的调制与编码策略(modulation and coding scheme,MCS)、更优的传输资源等等。该与质量相关的信息可以是信道状态信息(channel state information,CSI)，CSI包括但不限于信道质量指示(channel quality indicator,CQI)、预编码矩阵指示(precoding matrix indicator,PMI)、预编码类型指示(precoding type indicator,PTI)和秩指示(rank indication,RI)。作为一种实现方式，终端设备可以对网络设备发送的信道状态信息参考信号(channel state information-reference signal,CSI-RS)进行测量，以获得CSI。
在LTE通信系统中，网络设备发送的CSI-RS所映射的资源位置和CSI-RS的端口数目、CSI-RS的配置相关。如图5a所示，端口数为1或2时(例如，CSI-RS通过端口15和/或16发送)，CSI-RS映射的资源位置共有32种可能，分别对应存在灰色且数字编号的RE，RE中的数字从0到31；如图5b所示，端口数为4时(例如，CSI-RS通过端口15、16、17和18发送)，CSI-RS映射的位置共有16种可能，端口15和16对应灰色阴影且存在数字的RE、端口17和18对应斜线阴影但存在数字的的RE。其中RE中的数字包括0～9和20～25；如图5c所示端口数为8时(例如，CSI-RS通过端口15、16、17、18、19、20、21、22发送)，CSI-RS映射的位置共有8种可能，端口15和16对应灰色阴影且存在数字的RE、端口17和18对应斜线阴影但存在数字的的RE，端口19和20对应竖线阴影且存在数字的的RE，端口21和22对应横线阴影且存在数字的的RE，RE中的数字包括0～5和20～22。这里，假设一个端口在1个RB上只映射1个RE。在时域上，LTE通信系统中的CSI-RS映射的资源位置是以一个子帧为最小重复单位。图5a(图5b或者图5c)所有带数字的部分组成了CSI-RS候选资源集合，在此基础上，网络设备可以通过信令指示CSI-RS实际映射的位置。
而在NR通信系统中，CSI-RS映射的资源位置相对于LTE通信系统来说，更为灵活，其可以存在多个映射图样(pattern)。例如，如图6a所示，设为pattern 1，表示通过1个端口发送的CSI-RS在一个符号上映射到的RE编号为#0、#4、#8。当然通过该端口发送的CSI-RS在一个符号上还可以映射到的RE编号为#1、#5、#9，或者#2、#6、#10，或者#3、#7、#11，还需要说明的是在一个子帧中，该符号，可以是符号#0至#13中的任意一个。如图6b所示，设为pattern 2，表示通过1个端口发送的CSI-RS在一个符号上映射到的RE编号为#0，当然，通过该端口发送的CSI-RS在一个符号上还可以映射到RE#1至#11中的任意一个。图6c至图6r可以依次类推，需要说明的是，图6a至图6r每个附图最下面的数字代表的是端口数目，每个附图最上方的数字代表的是pattern编号，一个格子代表一个RE，也即时域上对应一个符号，频域上对应一个子载波。一个方框所框出的RE(图6a框出的是三个方框，将其看做一个整体)是向终端设备进行指示的基本单位，一个pattern中所有被填图的RE都是指示给同一个终端设备的。而同一种方式填图的RE属于同一个码分复用(code division multiplexing,CDM)组，不同方式填图的RE则属于不同的CDM组。pattern13、14、16、17中至少需要配置2个符号位置，其中可以使用第一个连续两符号整 体中的第一个符号(符号1)的位置指示该第一个连续两符号整体的时域位置、使用第二个连续两符号整体中的第一个符号(符号2)的位置指示该第二个连续两符号整体的时域位置。在时域上，NR通信系统CSI-RS映射的资源位置的最小重复单位为1个符号、2符号、或者4个符号。如图6a-图6r的18中pattern中的一种或者多种pattern可以组成终端设备的CSI-RS资源集合。
在NR通信系统的CSI-RS和LTE通信系统的PDSCH可以映射在相同的资源上场景下，当LTE通信系统的PDSCH的频谱效率不高时，部分资源上，LTE通信系统的PDSCH受到NR通信系统的CSI-RS的干扰时，LTE通信系统的终端设备仍然能正确解调出PDSCH中的内容；但是由于NR通信系统的CSI-RS受到LTE通信系统的PDSCH干扰，会导致NR通信系统的终端设备上报的CSI情况比实际的CSI情况差，使得NR通信系统的基站的调度决策偏保守，从而造成NR通信系统的终端设备的吞吐量下降，进而整个NR通信系统的效率降低。
实施例一：
为了克服现有技术中存在的以上技术问题，本申请实施例提出了一种信息上报的方法，该方法可以应用于两个不同的通信系统进行频谱共享的场景下，并且如图7所示：
步骤701：终端设备从网络设备接收第一配置信息，所述第一配置信息用于所述终端设备确定第一通信系统的第一频域资源与第二通信系统的第二频域资源的重合区域。
步骤702：所述终端设备向所述网络设备上报所述第一通信系统在所述第一频域资源上的信道状态信息CSI，所述CSI的上报方式包括：上报所述终端基于所述第一频域资源中除所述重合区域获得的CSI和所述终端基于所述重合区域获得的CSI、上报所述终端基于所述第一频域资源获得的CSI和所述终端基于所述重合区域获得的CSI、或者上报所述终端基于所述第一频域资源中除所述重叠区域获得的CSI。
本申请实施例中的终端设备是位于第一通信系统中的终端设备，网络设备是支持第一通信系统的网络设备。示例的，该终端设备可以通过所述网络设备接入第一通信系统、获得第一通信系统提供的服务。如图8所示，包括了第一通信系统的网络架构。
如实施例开始部分所述，本申请实施例中所述的第一通信系统和第二通信系统可以分别为NR通信系统和LTE通信系统，以下，图7实施例就以第一通信系统和第二通信系统可以分别为NR通信系统和LTE通信系统为例进行表述，但是需要说明的是第一通信系统和第二通信系统可以分别前述提及的任何通信系统，或者后续演进的任何通信系统，只要第一通信系统和第二通信系统不为同一通信系统即可，本申请并不做任何限制。
步骤701中所述的第一配置信息，具体可以包括LTE通信系统载波的配置信息，所述LTE通信系统载波的配置信息可以包括LTE系统载波中心的子载波位置，LTE通信系统载波的带宽中的一个或者多个。如此终端设备便可获取LTE通信系统中第二频域资源的位置信息。作为一种实现方式，终端设备可以通过网络设备获取到NR通信系统中，也就是其接入的通信系统中，激活BWP的带宽大小和/或位置，如此终端设备便可获取NR通信系统中第一频域资源的位置信息。
基于以上假设，第一通信系统的第一频域资源可以理解为NR通信系统的激活BWP； 第二通信系统的第二频域资源可以理解为LTE通信系统的载波。
基于步骤701，终端设备就可以确定出NR通信系统和LTE通信系统在频域上的重合区域。示例地，NR通信系统的激活BWP的带宽为一段连续的频域范围，且为50MHz，LTE通信系统的载波的带宽为20MHz，图9a、图9b或图9c为两者重合方式的举例。这三种重合方式中，图9a、图9b的重合带宽为20MHz，图9c则小于20MHz。也就是说，终端设备还能够知道，当前的通信中，NR通信系统和LTE通信系统是处于频谱共享的场景。
为了克服现有技术中的技术缺陷，需要使用一种新的方法上报NR通信系统中的CSI。本申请实施例对第一通信系统的第一频域资源的CSI的上报方式做出了修正，相对于现有技术中终端设备将基于整个第一频域资源，也即NR通信系统的激活BWP，获得的CSI，作为NR通信系统在激活带宽上的CSI进行上报，步骤702中，终端设备将基于如下方式中的一种获得CSI作为NR通信系统在激活BWP上的CSI进行上报：
方式一：上报所述终端设备基于所述第一频域资源中除所述重合区域获得的CSI。
以图9a为例进一步说明：如图9a，重合区域为图示的20MHz带宽，那么终端设备在50MHz的NR通信系统的激活BWP(即第一频域资源)上，将仅针对除重合区域外的30MHz带宽(即第一频域资源中除所述重合区域的部分)上的CSI-RS资源进行测量，将基于该区域测量获得的CSI作向网络设备进行上报。
这种上报方式，避免了重合区域上可能不准确的测量对整个NR通信系统的激活BWP上的测量结果的影响，网络设备获得的信道质量信息是更准确的。
方式二：上报所述终端设备基于所述第一频域资源中除所述重合区域获得的CSI和所述终端设备基于所述重合区域获得的CSI。
仍然可以以图9a为例，方式二与方式一的区别在于，终端设备在50MHz的NR通信系统的激活BWP(即第一频域资源)上，不仅需要针对除重合区域外的30MHz带宽上(即第一频域资源中除所述重合区域的部分)的CSI-RS资源进行测量，还需要针对重合区域的20MHz带宽上的CSI-RS资源进行测量。其中，这两个测量是互相独立的。终端设备将基于这两个区域分别获得的CSI，并向网络设备进行上报。
这种上报方式，网络设备获得的是基于第一频域资源中除所述重合区域和基于所述重合区域获得的CSI，相对于第一种方式，网络设备还进一步获得了重合区域的CSI作为参考，如此在第一频域资源范围内的CSI更为全面，网络设备可以基于此优化调度该终端设备的方式，比如选择更可靠的MCS、更优的传输资源等等，以提高该终端设备的吞吐量和整个通信系统的效率。
方式三：上报所述终端设备基于所述第一频域资源获得的CSI和所述终端设备基于所述重合区域获得的CSI。
仍然可以以图9a为例，在方式三中，作为另外一种选择，终端设备在50MHz的NR通信系统的激活BWP(即第一频域资源)上，需要针对该50MHz的的激活BWP上的CSI-RS资源进行测量，还需要针对重合区域的20MHz带宽上的CSI-RS资源中映射的CSI-RS进行测量。其中，这两个测量是互相独立的。所述终端设备将基于这两个区域分别获得的CSI，并向网络设备进行上报。
这种上报方式，网络设备获得的是基于第一频域资源和基于所述重合区域获得的CSI， 如此网络设备获得的信道质量相关的信息也是全面的，网络设备可以基于此优化调度该终端设备的方式，比如选择更可靠的MCS、更优的传输资源等等，以提高该终端设备的吞吐量和整个通信系统的效率。
作为一种实现方式，该网络设备可以向终端设备发送第二配置信息，所述第二配置信息可以是CSI配置信息，用于所述终端设备确定CSI的上报格式(format)。该上报格式包括宽带上报(wideband reporting)或者子带上报(subband reporting)。当宽带上报被配置，表示是基于整个给终端设备配置的频域资源进行测量来获得CSI；当子带上报被配置，是基于给终端设备配置的频域资源的子区域(子带)进行测量来获得CSI，获得的CSI的个数为多个。
需要说明的是，当上报格式为宽带上报时，如上所述的三种上报方式都可以适用。而当上报格式为子带上报时，只有方式二能够适用。
作为一种实现方式，网络设备可以向该终端设备发送第一指示信息，该指第一示信息起到使能的作用，指示该终端设备是否采用如上三种方式中的一种进行CSI的上报。可选的，这个第一指示信息可以包含在下行控制信息(downlink control information,DCI)中，通过一个比特位进行指示。该DCI可以是终端设备级(UE级)的DCI，还可以是组(group)级的DCI。
网络设备和终端设备可以通过协议约定，在NR通信系统和LTE通信系统存在重合区域的情况下，终端设备采用如上三种上报方式中的何种方式进行上报。当然，在NR通信系统和LTE通信系统存在重合区域的情况下，网络设备亦可以通过第二指示信息指示所述终端设备采用如上三种上报方式中的何种方式进行上报。该第二指示信息亦可承载在DCI中。这种动态的指示方式相对于协议约定的方式，更为灵活。
作为一种实现方式，该CSI包括CQI、PMI、PTI和RI中的至少一种。
作为另一种实现方式，该CSI可以承载在物理上行共享信道(physical uplink shared channel,PUSCH)或者物理上行控制信道(physical uplink control channel,PUCCH)上。
本申请实施例一的技术方案，通过采取新设计的三种CSI上报方式中的一种，相对于现有技术中单独上报基于整个第一频域资源的CSI的上报方式，更能准确地反映第一通信系统中的信道质量状况，避免了造成第一通信系统中的吞吐量和通信效率的损失。
实施例二
本申请实施例还提出了另一种信息上报的方法，如图10所示，同样可以克服上述提及的技术问题，其应用场景和网络架构实施例一类似。
步骤1001：终端设备从网络设备接收第一配置信息，所述第一配置信息用于所述终端设备确定第一通信系统的第一频域资源与第二通信系统的第二频域资源存在重合区域；
步骤1002：所述终端设备通过对所述第一频域资源上CSI-RS资源集合的测量，向所述网络设备上报所述第一通信系统在所述第一频域资源上的信道状态信息CSI，其中，在所述第一频域资源，第一通信系统的CSI-RS资源集合为所述第二通信系统的CSI-RS候选资源集合的子集。
与实施例一类似的，本申请实施例中的终端设备是位于第一通信系统中的终端设备，网络设备是支持第一通信系统的网络设备。示例的，该终端设备可以通过所述网络设备接入第一通信系统、获得第一通信系统提供的服务。其网络架构可以参照图8。
同样，以第一通信系统和第二通信系统可以分别为NR通信系统和LTE通信系统为例进行表述，但是并不表示对对第一通信系统和第二通信系统存在任何限制。
步骤1001中的第一配置信息，具体内容可以与实施例一步骤701中的第一配置信息相同或者相类似，这里不再赘述。
作为一种实现方式，终端设备可以通过网络设备获取到NR通信系统中，也就是其接入的通信系统中，激活BWP的带宽大小和/或位置。
基于以上假设，第一通信系统的第一频域资源可以理解为NR通信系统的激活BWP；第二通信系统的第二频域资源可以理解为LTE通信系统的载波。
基于该第一配置信息，终端设备可以确定NR通信系统激活BWP和LTE通信系统的载波在频域上存在重合区域。也即，终端设备能够知道，当前的通信中，NR通信系统和LTE通信系统是处于频谱共享的场景。
可选的，终端设备还可以基于该第一配置信息进一步确定出NR通信系统和LTE通信系统的重合区域。具体的确定方式，也可以参见对步骤701的具体说明。
在上报NR通信系统的激活BWP上的CSI时，相对于实施例一中采用对上报方式进行修正的技术方案，本实施例从CSI-RS资源角度，通过规定NR通信系统中CSI-RS资源的位置来避免LTE通信系统中的PDSCH对NR通信系统中CSI测量可能造成的干扰。
在步骤1002中，针对NR通信系统的激活BWP上的CSI，终端设备仍可以采用与现有技术中相同的上报方式进行上报。其上报的格式可以为宽带上报或者窄带上报。与现有技术不同的是，这里规定：在NR通信系统的激活BWP上，NR通信系统的CSI-RS资源集合为LTE通信系统的CSI-RS候选资源集合的子集。
具体来说，LTE通信系统中的CSI-RS候选资源集合可以理解为由图5a(或者5b、或者5c)中带有数字的RE组成。而NR通信系统中CSI-RS资源集合如前所述，更为灵活，存在多个映射pattern。也就是说，实施例二要求终端设备期望接收到的NR通信系统的映射pattern对应的CSI-RS资源集合需要与LTE通信系统中的CSI-RS候选资源集合重叠、或者CSI-RS候选资源集合的部分重叠。举例来说，当终端设备期望(例如可以通过网络设备给终端设备进行指示)获得NR通信系统CSI-RS资源的时域位置为符号5、6、12、13中的至少一个时，其所对应的频域位置为子载波2、3、8、9中的至少一个；或当终端期望接收到NR通信系统CSI-RS资源的时域位置为符号8、符号8或符号10中的至少一个。此时，需要从NR通信系统中的映射pattern中找出符合以上要求的pattern，例如pattern2、3、5、7或者8，即图6b、图6c、图6e、图6g或者图6h都可以满足要求。
规定在NR通信系统的激活BWP上，NR通信系统的CSI-RS资源集合为LTE通信系统的CSI-RS候选资源集合的子集的原因是，在CSI-RS候选资源集合上，将不会映射有LTE通信系统的PDSCH资源，可以通过使能LTE通信系统的零功率CSI-RS配置，避免对NR通信系统CSI-RS测量的干扰，从而基于此获得的NR通信系统的激活BWP上的CSI是更为准确的。
作为一种实现方式，该网络设备可以向终端设备发送第二配置信息，所述第二配置信息可以是CSI配置信息，用于所述终端设备确定CSI的上报格式(format)。该上报格式包括宽带上报(wideband reporting)或者子带上报(subband reporting)。当宽带上报被配置，表示是基于整个给终端设备配置的带宽进行测量来获得CSI；当子带上报被配置，表示是基于给终端设备配置的带宽的子带进行测量来获得CSI，获得的CSI的个数为多个。
作为一种实现方式，该网络设备可以向该终端设备发送第一指示信息，用于指示NR通信系统的CSI-RS资源集合的时域位置和NR通信系统的CSI-RS的映射pattern。可选的，这个第一指示信息可以包含在下行控制信息(downlink control information,DCI)中，通过比特位进行指示。该DCI可以是终端设备级(UE级)的DCI，还可以是组(group)级的DCI。可选的，网络设备和终端设备还可以通过协议约定NR通信系统的CSI-RS的映射pattern，再通过第二指示信息，指示NR通信系统的CSI-RS资源集合的时域位置。这两种实现方式，前者更为灵活，后者则可以节约信令开销。
作为一种实现方式，该CSI包括CQI、PMI、PTI和RI中的至少一种。
作为另一中实现方式，该CSI可以承载在物理上行共享信道(physical uplink shared channel,PUSCH)或者物理上行控制信道(physical uplink control channel,PUCCH)上。
本申请实施例二的技术方案，通过规定在所述第一频域资源，第一通信系统的CSI-RS资源集合为所述第二通信系统的CSI-RS候选资源集合的子集，更能准确地反映第一通信系统中的信道质量状况，避免了造成第一通信系统中的吞吐量和通信效率的损失。
本申请中的各个实施例可以单独使用，也可以相互结合使用，以达到不同的技术效果。
