在220中,在接收到该激活信令之后,该终端设备向该网络设备持续性上报该第一CSI,直到接收到该网络设备发送的去激活信令,其中,该去激活信令用于指示该终端设备停止上报该第一CSI。
可选地,该去激活信令可以为DCI或MAC信令。
可选地,该终端设备通过物理上行共享信道(Physical Uplink Shared Channel,PUSCH)。
可选地,该终端设备通过物理上行控制信道(Physical Uplink Control Channel,PUCCH)向该网络设备持续性上报该第一CSI。
通过PUSCH进行持续性的CSI上报的可以承载更多的反馈信息,特别在上行资源充裕的情况下。
可选地,终端设备采用相同的传输方式,向所述网络设备持续性上报所述第一CSI。
其中,本申请实施例提到的相同的传输方式包括但不限于采用相同的 (Multiple Input Multiple Output,MIMO)传输模式,相同的调制编码方式,相同的正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号数和相同的频域资源中的至少一项。
例如,可以采用上行发送分集的MIMO传输方式,采用较低的调制编码方式,从而保证CSI的可靠性。
或者,可以占用固定的物理资源块(Physical Resource Block,PRB)数,从而节省信令配置的开销。
可选地,该第一CSI包括以下内容中的至少一项:CSI-RS资源指示符(CSI-RS resource Indicator,CRI)、秩指示(Rank Indication,RI)、预编码矩阵指示符(Pre-coding Matrix Indicator,PMI)、信道质量信息(Channel Quality information,CQI)、信道信息的量化值和干扰的量化值。
可选地,该信道信息的量化值可以是信道协方差矩阵的量化值,也可以是信道特征向量的量化值,也可以是信道估计本身的量化值。
可选地,该激活信令包括第一信息,该第一信息用于指示该第一CSI包括的内容;该终端设备根据该第一信息,向该网络设备持续性上报该第一CSI,该第一CSI包括该第一信息指示的内容。
可选地,该第一信息用于指示如下内容中的一项:
CRI;或者
RI,PMI和CQI;或者
CRI,RI,PMI和CQI;或者
RI和CQI;或者
CRI,RI和CQI。
其中,激活信令可以通过第一信息包括的比特的取值,指示第一CSI需要包括的内容,例如,第一信息可以为1个比特,比特的取值可以指示两种CSI内容之一:{CRI,RI/PMI/CQI},例如,在该比特的取值为0时,表明第一CSI需要包括CRI,在该比特的取值为1,表明第一CSI需要包括RI,PMI和CQI。
或者,该1比特的取值可以指示以下两种内容之一{CRI,RI/PMI/CQI/CRI},或者,该1比特的取值可以指示以下两种内容之一{CRI,RI/CQI}。
可选地,该终端设备进行持续性CSI测量,以获取该第一CSI。
其中,持续性进行CSI测量的资源可以是用于周期性CSI-RS传输的资源。
其中,用于周期性CSI-RS传输的资源通常是网络设备配置的CSI-RS资源,它的配置信息可以包括时域偏移和周期等,从而,终端设备可以根据该配置信息,基于该用于周期CSI-RS传输的资源,进行CSI测量。
可选地,网络设备可以通过高层信令或者DCI信令预先向终端设备指示该用于周期的CSI-RS传输的资源。
例如,可以通过DCI信令从MAC层消息或者RRC消息配置的多个CSI-RS资源中指示一个CSI-RS资源作为进行该持续性CSI测量的资源。
其中,一种资源配置可以对应一个CSI-RS资源,也即多个CSI-RS资源中的一个CSI-RS资源与其它个CSI-RS资源的资源配置不同,例如,可以是时域偏移和周期中的至少一种不同。
可选地,如果该用于持续性CSI测量的CSI-RS资源包含多个CSI-RS资源,终端设备可以假设多个资源上传输的CSI-RS信号使用相同的波束,或者使用不同的波束。或者,如果持续性CSI测量的CSI-RS资源只包含一个CSI-RS资源,终端设备可以假设该资源上传输的CSI-RS信号的不同端口使用相同的波束,或者使用不同的波束。如果终端设备假设采用不同的波束,则所述第一CSI中需要包含CSI-RS资源指示符(CSI-RS resource Indicator,CRI)。
可选地,在进行持续性CSI测量时,每次测量得到的第一CSI的内容可以不同。
可选地,对于不同的CSI内容,可以从不同的资源配置的CSI-RS资源上获取,并且可以不在一次CSI上报中携带,当然也可以在一次CSI上报中携带。
可选地,对于不同的内容,可以从相同的资源配置的CSI-RS资源,但是不同的时域资源单元中获取,并且可以不在一次CSI上报中携带,当然也可以在一次CSI上报中携带。
可选地,该终端设备根据该第一CSI包括的内容,确定以下中的至少一种,并根据以下中的至少一种,进行持续性CSI测量,以获取该第一CSI:
进行该持续性CSI测量的资源,进行该持续性CSI测量时采用的CSI-RS端口的数量,以及进行该持续性CSI测量的资源上的CSI-RS的发送波束的 假设。
例如,如果第一CSI只有CRI,则终端设备需要基于多个CSI-RS资源进行CSI测量;如果第一CSI内容包含RI和CQI,或者包含RI、PM和CQI,则终端设备只需要基于一个CSI-RS资源进行CSI测量。
例如,如果第一CSI只有CRI,则终端设备需要用于进行CSI测量的资源的前1或2个CSI-RS端口(端口0或0,1)进行CSI测量;如果第一CSI包含RI和CQI,或者包含RI、PMI和CQI,则终端设备需要用于进行CSI测量的资源上的所有CSI-RS端口进行CSI测量。
例如,如果第一CSI内容中只有CRI,则终端设备假设测量基于的CSI-RS资源上的不同CSI-RS端口采用不同的发送波束,从而进行CSI测量;如果第一CSI内容包含RI和CQI,或者包含RI、PMI和CQI,则终端假设测量基于的CSI-RS资源上的不同CSI-RS端口采用相同的发送波束。
可选地,所述终端设备根据所述第一CSI包括的内容,确定第一次上报所述第一CSI的第一时域资源;所述终端设备在所述第一时域资源上,第一次上报所述第一CSI。
可选地,所述终端设备根据所述第一次上报所述第一CSI的第一时域资源,以及预先获得的持续性上报所述第一CSI的周期,确定后续持续性上报第一CSI的时域资源。
可选地,如果并非每次上报的第一CSI内容均相同,终端设备可以根据第一次上报的该第一CSI包括的内容,确定第一次上报该第一CSI的第一时域资源;在该第一时域资源上,第一次上报该第一CSI。
例如,如果第一次上报的第一CSI中只包含CRI,则可以采用较短的反馈时延,例如激活信令的接收和第一次CSI反馈之间相差1个时隙。
例如,如果第一次上报的第一CSI包含RI、PMI和CQI,或者包含RI和CQI,则可以采用较长的反馈时延,例如激活信令的接收和第一次CSI反馈之间相差2个时隙;
例如,如果第一次上报的第一CSI包含信道协方差矩阵,或者干扰协方差矩阵,则需要更长的反馈时延,例如激活信令的接收和第一次CSI反馈之间相差3个时隙。
可选地,该激活信令包括第二信息,该第二信息用于指示第一次上报该第一CSI的时间;该终端设备根据该第二信息,确定第一次上报该第一CSI 的第二时域资源,并在该第二时域资源上向网络设备第一次上报该第一CSI。
可选地,所述终端设备根据所述第一次上报所述第一CSI的第二时域资源,以及预先获得的持续性上报所述第一CSI的周期,确定后续持续性上报第一CSI的时域资源。
可选地,在本申请实施例中,第二信息可以通过指示接收到激活信令与第一次上报第一CSI的定时关系的方式指示该第一次上报该第一CSI的时间。具体地说,该定时关系可以用于指示第一次上报第一CSI的时间与接收到该激活信令相差的时间资源单元的数量,例如,子帧的数量或时隙的数量等。
如果第一次上报的第一CSI包括的内容的不同,该第二信息定时关系可以不同。也就是说,不同的定时关系可以通过同一指示域来指示,也即对于不同的CSI内容,同一指示域指示的定时关系不同。
例如,如下表1所示,定时关系指示域可以包括两个2比特,假设指示域的比特的取值为01,则表示,在第一次上报的第一CSI只包含CRI时,反馈时延N(即接收到触发信令与CSI上报相差的时域资源单元的数量)为1,在第一次上报的第一CSI包括RI、PMI和CQI时,反馈时延N为2。
表1
Figure PCTCN2017075243-appb-000001
可选地,在本申请实施例中,根据第一次上报的第一CSI包括的内容,确定第一次上报的时域资源,也可以具有以下理解:
对于并非每次上报的内容均相同的情况下,可以确定每一种内容第一次上报的时间,并按照该时间,第一次上报相应的内容。例如,仍以上表1所示,假设终端设备需要上报CRI,以及上报RI,PMI和CQI,可以按照表1所示,确定出第一次上报CRI的开始时间,以及第一次上报RI、PMI和CQI的开始时间。
可选地,在连续的用于上行传输的时域资源单元上,终端设备向该网络设备持续性上报该第一CSI;或,以一定的周期向该网络设备周期性上报该第一CSI。
可选地,对于不同的内容的第一CSI,上报的周期可以不同,和/或每次上报所占用的资源大小不同。
可选地,该激活信令包括第三信息,该第三信息用于指示上报该第一CSI的资源,例如,上报第一CSI的周期、每次反馈所占用的资源大小和不同内容的CSI反馈的时域偏移等;在该第三信息指示的该资源上,向该网络设备持续性上报该第一CSI。
可选地,在本申请实施例中,终端设备可以根据执行CSI测量时的依赖关系,确定每次上报的该第一CSI,并进行上报。
在一种实现方式中,该每次上报的该第一CSI的测量不依赖于其它次上报的第一CSI。
例如,每次上报的CSI是一个CSI进程对应的CSI,不同CSI进程对应的CSI不在一次上报中携带。
例如,每次上报的CSI是相同的测量资源获取的CSI,不同测量资源获取的CSI不在一次上报中携带。
例如,每次上报的CSI是基于相同的下行传输假设(CSI-RS的下行发送波束假设)获取的CSI,基于不同的下行波束假设获取的CSI不在一次上报中携带。
在另一种实现方式中,测量时具有依赖关系的第一CSI,在连续的上报资源上进行上报。
例如,在上报对应不同级别的码本的CSI时,可以在前一上报资源上上报预编码信息W1对应的CSI,可以在其次的上报资源上上报预编码信息W2和W3对应的CSI,其中W2和W3基于W1计算得到,且由W1,W2和W3才能得到的完整的预编码信息。
可选地,该激活信令包括第四信息,该第四信息用于指示各次上报的该第一CSI在测量时的依赖关系;终端设备根据执行CSI测量时的依赖关系以及该第四信息,确定每次上报的该第一CSI,并进行上报。
可选地,在本申请实施例中,可以将测量时具有依赖关系的CSI划分为同一CSI组,测量时不具有依赖关系的CSI划分为属于不同的CSI组。也就 是说,一个CSI组包括至少一种CSI内容,不同的CSI组之间是独立的,但CSI组内的CSI内容之间是相互关联的(即一个CSI内容需要基于另一个CSI内容计算得到,或者两个CSI内容是基于相同的资源计算得到)。则一个组中不同的CSI内容可以在连续的上报资源上上报,或者,一个组中的所有内容在相同的上报资源上上报。
可选地,终端设备接收到调度上行数据传输的第一DCI信令;根据该第一DCI信令,该终端设备确定需要在持续性上报该第一CSI的第一时域资源单元中进行该上行数据的传输;在该第一时域资源单元中,以与该上行数据进行复用的方式,向该网络设备上报该第一CSI。
具体地说,如果终端设备在持续CSI反馈的过程中,在某个时域资源单元中收到网络设备调度上行数据传输的DCI,则将该时域资源单元中需要反馈的CSI与需要传输的上行数据进行复用后,基于所述DCI进行传输。在这个时域资源单元之后,仍然按照原来的持续性CSI上报的配置进行CSI上报。
可选地,终端设备可以只在使用离散傅里叶变换扩频的正交频分复用(Discrete Fourier transform Orthogonal Frequency Division Multiplexing based Spread Spectrum,DFT-S-OFDM)多址方式下,进行上行数据与CSI的复用;在循环前缀正交频分复用(Cyclic Prefix Orthogonal Frequency Division Multiplexing,CP-OFDM)多址方式下独立传输所述CSI和上行数据,此时,在第一时域资源单元中,终端设备可以暂停第一CSI的传输;
或者,不论采用何种上行多址方式,终端设备均可以进行上行数据和CSI的复用。
在该种情况下,网络设备可以在第一时域资源单元中基于该DCI的配置,获取终端设备上报的CSI和上行数据。
因此,在本申请实施例中,通过PUSCH进行CSI的上报,并且与突发的数据传输进行复用,可以提高资源的利用率,支持更大的反馈信令开销。
可选地,终端设备接收到调度非周期CSI上报的第二DCI信令;该终端设备根据该第二DCI信令,确定需要在持续性上报该第一CSI的第二时隙中进行非周期CSI上报;基于该第一DCI信令进行非周期CSI上报,在该第二时域资源单元中暂停通过持续性方式上报该第一CSI。
具体地说,如果终端设备在持续CSI反馈的过程中在某个时域资源单元中收到网络设备调度非周期CSI上报的DCI,则基于该DCI的配置信息进行 所述时域资源单元中的CSI上报。在该时域资源单元中,所述第一CSI可以放在所述非周期性的CSI中进行上报,也可以直接不上报所述第一CSI。在这个时域资源单元之后,仍然按照原来的持续性CSI上报的配置进行CSI上报。
在该种情况下,网络设备可以在第二时域资源单元中基于该DCI的配置,获取终端设备上报的CSI。
因此,在需要上报非周期CSI时,暂停持续性CSI的上报,并在上非周期的CSI之后,进行持续性CSI上报,可以实现CSI上报的多样性,更大的满足通信需求。
图3是根据本申请实施例的无线通信方法300的示意性流程图。如图3所示,该方法300包括以下内容。
在310中,网络设备向终端设备发送激活信令,该激活信令用于激活该终端设备持续性上报第一CSI。
在320中,该网络设备持续性接收该终端设备上报的该第一CSI。
在330中,该网络设备向该终端设备发送去激活信令并停止接收该第一CSI,该去激活信令用于指示该终端设备停止上报该第一CSI。
可选地,该网络设备通过物理上行共享信道PUSCH或者物理上行控制信道PUCCH,持续性接收该第一CSI。
可选地,该第一CSI包括以下内容中的至少一项:
CRI、RI、PMI、CQI、信道信息的量化值和干扰的量化值。
可选地,在该第一CSI包括CRI,根据该CRI,网络设备获取用于下行调度的下行波束赋形的波束信息。
具体地,下行调度可以包括下行预编码,则可以根据该下行波束赋形的波束信息,进行下行预编码。
可选地,在该第一CSI包括RI、PMI和CQI时,网络设备根据RI、PMI和CQI,对该终端设备进行下行数据的调度。
可选地,在该第一CSI包括RI和CQI时,网络设备根据RI和CQI,对该终端设备进行下行数据的调度。
可选地,该激活信令包括第一信息、第二信息、第三信息和第四信息中的至少一种,其中,
该第一信息用于指示该第一CSI包括的内容;
该第二信息用于指示第一次上报该第一CSI的时间;
该第三信息用于指示上报该第一CSI的资源;
该第四信息用于指示各次上报的该第一CSI在测量时的依赖关系。
应理解,方法300中的网络设备可以实现方法200中提到的终端设备实现的相应功能,为了简洁,在此不再赘述。
因此,在本申请实施例中,终端设备接收网络设备发送的用于激活所述终端设备持续性上报第一CSI的激活信令之后,所述终端设备向所述网络设备持续性上报所述第一CSI,直到接收到所述网络设备发送的用于指示所述终端设备停止上报所述第一CSI的去激活信令,因此,由于持续性进行CSI上报,可以使得网络设备得到足够的CSI,可以提升调度的质量,从而可以提升通信性能,并且基于激活信令和去激活信令进行触发CSI上报的开始和结束,可以实现按需进行CSI的获取,从而可以进一步提升通信性能。
