背景技术Background technique
在目前的协议中,准同位(quasi colocation,QCL)关系用于表示多个天线端口(或参考信号资源)之间具有一个或多个相同或者相类似的通信特征。对于具有QCL关系的多个天线端口,可以采用相同或者类似的通信配置。In current protocols, a quasi colocation (QCL) relationship is used to indicate that multiple antenna ports (or reference signal resources) have one or more identical or similar communication characteristics. For multiple antenna ports with a QCL relationship, the same or similar communication configuration may be employed.
具体的,若两个天线端口具有QCL关系,则一个天线端口传输符号的信道大尺度特性可以从另一个天线端口传输符号的信道大尺度特性推断得到。其中,该大尺度特性可以包括时延扩展(delay spread)、多普勒扩展(Doppler spread)、多普勒频移(Doppler shift)、平均时延(average delay)、平均增益、空间接收参数(spatial Rx parameters)等。Specifically, if the two antenna ports have a QCL relationship, the large-scale channel characteristics of the symbols transmitted by one antenna port can be inferred from the large-scale characteristics of the channel transmitted by the other antenna port. The large-scale characteristics may include delay spread, Doppler spread, Doppler shift, average delay, average gain, and spatial reception parameters ( spatial Rx parameters), etc.
通常,QCL关系可以由传输配置指示(transmission configuration indicator state,TCI)配置。具体的,可以将不同参考信号或信道关联到不同的TCI状态(TCI-state),通过TCI-state中的QCL信息为不同参考信号或信道配置不同的QCL关系。In general, the QCL relationship can be configured by a transmission configuration indicator (TCI). Specifically, different reference signals or channels can be associated with different TCI states (TCI-states), and different QCL relationships can be configured for different reference signals or channels through the QCL information in the TCI-state.

具体实施方式Detailed ways
为了方便理解本申请实施例中的方案,首先给出相关技术的简要介绍或定义如下:In order to facilitate understanding of the solutions in the embodiments of the present application, a brief introduction or definition of related technologies is first given as follows:
1、天线端口(antenna port)1. Antenna port
天线端口是逻辑上的概念,一个天线端口可以对应一个物理发射天线,也可以对应多个物理发射天线。在这两种情况下,终端的接收机(receiver)都不会去分解来自同一个天线端口的信号。因为从终端的角度来看,不管信道是由单个物理发射天线形成的,还是由多个物理发射天线合并而成的,这个天线端口对应的参考信号(Reference Signal)就定义了这个天线端口,例如,对应解调参考信号(de-modulation reference signal,DMRS)的天线端口即DMRS端口,终端都可以根据这个参考信号得到这个天线端口的信道估计。An antenna port is a logical concept. An antenna port can correspond to one physical transmit antenna, or can correspond to multiple physical transmit antennas. In both cases, the receiver of the terminal will not decompose the signal from the same antenna port. Because from the perspective of the terminal, regardless of whether the channel is formed by a single physical transmit antenna or a combination of multiple physical transmit antennas, the reference signal (Reference Signal) corresponding to this antenna port defines this antenna port, for example , corresponding to the antenna port of the demodulation reference signal (de-modulation reference signal, DMRS), that is, the DMRS port, and the terminal can obtain the channel estimation of the antenna port according to the reference signal.
每个天线端口对应一个时频资源网格(time/frequency resource grid),有其独自的参考信号。一个天线端口就是一个信道,终端可以根据这个天线端口对应的参考信号进行信道估计和数据解调。Each antenna port corresponds to a time/frequency resource grid and has its own reference signal. An antenna port is a channel, and the terminal can perform channel estimation and data demodulation according to the reference signal corresponding to the antenna port.
2、QCL关系:2. QCL relationship:
QCL关系用于表示多个天线端口(或资源)之间具有一个或多个相同或者相类似的通信特征。对于具有QCL关系的多个天线端口(或资源),可以采用相同或者类似的通信配置。The QCL relationship is used to indicate that multiple antenna ports (or resources) have one or more identical or similar communication characteristics. For multiple antenna ports (or resources) with a QCL relationship, the same or similar communication configuration may be employed.
具体的,若两个天线端口具有QCL关系,则一个天线端口传输符号的信道大尺度特性可以从另一个天线端口传输符号的信道大尺度特性推断得到。或者说,具有QCL关系的天线端口具有相同的大尺度特性,或者,一个天线端口的大尺度特性可用于确定与该天线端口具有QCL关系的另一个天线端口的大尺度特性,或者,两个天线端口间的大尺度特性差小于某阈值。Specifically, if the two antenna ports have a QCL relationship, the large-scale channel characteristics of the symbols transmitted by one antenna port can be inferred from the large-scale characteristics of the channel transmitted by the other antenna port. Alternatively, antenna ports with a QCL relationship have the same large-scale properties, or the large-scale properties of one antenna port can be used to determine the large-scale properties of another antenna port with a QCL relationship to that antenna port, or, both antennas The large-scale characteristic difference between ports is less than a certain threshold.
其中,所述大尺度特性可以包括以下一项或多项:时延扩展(delay spread),多普勒扩展(Doppler spread),多普勒频移(Doppler shift),平均时延(average delay),平均增益,空间接收参数(spatial Rx parameters)。其中,空间接收参数可以包括以下的一项或多项:到达角(angle of arrival,AOA)、平均AOA、AOA扩展、离开角(angle of departure,AOD)、平均AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数、发射波束、接收波 束以及资源标识。The large-scale characteristics may include one or more of the following: delay spread, Doppler spread, Doppler shift, average delay , average gain, spatial Rx parameters. The spatial reception parameters may include one or more of the following: angle of arrival (AOA), average AOA, AOA extension, angle of departure (AOD), average AOD, AOD extension, receiving antenna space Correlation parameters, transmit antenna spatial correlation parameters, transmit beams, receive beams, and resource identifiers.
其中,上述角度可以为不同维度的分解值,或不同维度分解值的组合。天线端口为具有不同天线端口编号的天线端口,和/或,具有相同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口,和/或,具有不同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口。资源标识可以包括:信道状态信息参考信号(channel state information reference signal,CSI-RS)资源标识,或探测参考信号(sounding reference signal,SRS)资源标识,或同步信号块(synchronous signal block,SSB)资源标识,或物理随机接入信道(physical random access channel,PRACH)上传输的前导序列的资源标识,或解调参考信号(demodulation reference signal,DMRS)的资源标识,用于指示资源上的波束。Wherein, the above angle may be a decomposition value of different dimensions, or a combination of decomposition values of different dimensions. Antenna ports are antenna ports with different antenna port numbers, and/or, antenna ports with the same antenna port number that transmit or receive information in different time and/or frequency and/or code domain resources, and/or, have different antenna ports The antenna port number is the antenna port that transmits or receives information in different time and/or frequency and/or code domain resources. The resource identifiers may include: channel state information reference signal (CSI-RS) resource identifiers, or sounding reference signal (SRS) resource identifiers, or synchronous signal block (synchronous signal block, SSB) resource identifiers The identifier, or the resource identifier of the preamble sequence transmitted on the physical random access channel (PRACH), or the resource identifier of the demodulation reference signal (demodulation reference signal, DMRS), is used to indicate the beam on the resource.
需要说明的是,本申请中的同步信号块指的是同步信号/物理广播信道块(synchronous signal/physical broadcast channel block,SS/PBCH block,也可以简称为SSB)。It should be noted that the synchronization signal block in this application refers to a synchronization signal/physical broadcast channel block (synchronous signal/physical broadcast channel block, SS/PBCH block, also referred to as SSB for short).
在新无线(new radio,NR)协议中,QCL关系可以基于不同的参数分为以下四种类型:In the new radio (NR) protocol, the QCL relationship can be divided into the following four types based on different parameters:
类型A(type A):多普勒频移、多普勒扩展、平均时延、时延扩展;Type A (type A): Doppler shift, Doppler spread, average delay, delay spread;
类型B(type B):多普勒频移、多普勒扩展;Type B (type B): Doppler shift, Doppler spread;
类型C(type C):多普勒频移、平均时延;Type C (type C): Doppler shift, average delay;
类型D(type D):空间接收参数。Type D (type D): The space receives parameters.
其中,类型为A或B的QCL用于指示信道估计信息;类型为C的QCL用于指示RSRP等测量信息;类型为D的QCL用于指示不同的波束。The QCL of type A or B is used to indicate channel estimation information; the QCL of type C is used to indicate measurement information such as RSRP; the QCL of type D is used to indicate different beams.
可以理解的是,由于天线端口对应的参考信号定义了天线端口,因此,两个天线端口具有QCL关系,也可以理解为定义该两个天线端口的两个参考信号具有QCL关系。It can be understood that, since the reference signals corresponding to the antenna ports define the antenna ports, the two antenna ports have a QCL relationship, and it can also be understood that the two reference signals defining the two antenna ports have a QCL relationship.
3、波束:3. Beam:
波束是一种通信资源。波束可以是宽波束,或者窄波束,或者其他类型波束。形成波束的技术可以是波束成形技术或者其他技术手段。波束成形技术可以具体为数字波束成形技术,模拟波束成形技术,混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。A beam is a communication resource. The beams can be wide beams, or narrow beams, or other types of beams. The beam forming technology may be beamforming technology or other technical means. The beamforming technology may be specifically a digital beamforming technology, an analog beamforming technology, and a hybrid digital/analog beamforming technology. Different beams can be considered as different resources. The same information or different information can be sent through different beams.
可选的,可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束可以由一个或多个天线端口所形成,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可以看作是一个天线端口集。Optionally, multiple beams with the same or similar communication characteristics may be regarded as one beam. A beam can be formed by one or more antenna ports for the transmission of data channels, control channels and sounding signals, etc. One or more antenna ports forming a beam can be viewed as a set of antenna ports.
波束包括发射波束和接收波束。发射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,接收波束可以是指天线阵列对无线信号在空间不同方向上进行加强或削弱接收的分布。Beams include transmit beams and receive beams. Transmitting beams may refer to the distribution of signal strengths formed in different directions in space after signals are transmitted by antennas, and receiving beams may refer to the distribution of antenna arrays that enhance or weaken the reception of wireless signals in different spatial directions.
4、传输配置指示(transmission configuration indication,TCI)状态(state):4. Transmission configuration indication (TCI) state (state):
TCI-state用于指示不同的物理信号和/或物理信道之间的QCL信息,QCL关系通过QCL信息指示。例如,TCI-state可以用于指示CSI-RS与DMRS之间的QCL信息。The TCI-state is used to indicate the QCL information between different physical signals and/or physical channels, and the QCL relationship is indicated by the QCL information. For example, TCI-state may be used to indicate QCL information between CSI-RS and DMRS.
示例性的,TCI-state的信元格式如下所示:Exemplarily, the cell format of TCI-state is as follows:
Figure PCTCN2020121697-appb-000001
Figure PCTCN2020121697-appb-000001

Figure PCTCN2020121697-appb-000002
其中,cell域用于指示配置该QCL-info所指示的参考信号的服务小区。The cell field is used to indicate the serving cell where the reference signal indicated by the QCL-info is configured.
bwp-Id域用于指示承载该QCL-info所指示的参考信号的下行BWP。The bwp-Id field is used to indicate the downlink BWP that carries the reference signal indicated by the QCL-info.
qcl-Type域用于指示该QCL-info所指示的参考信号所对应的QCL类型。The qcl-Type field is used to indicate the QCL type corresponding to the reference signal indicated by the QCL-info.
ReferenceSignal域用于配置源参考信号。其中,本申请中的源参考信号指在QCL关系中作为参考的信号。例如,若参考信号A与参考信号B具有QCL关系,且参考信号A对应的大尺度特性能够从参考信号B对应的大尺度特性推断得到,则参考信号B即为源参考信号。当然,如上所述的信元格式,源参考信号也可以为SSB。The ReferenceSignal field is used to configure the source reference signal. Wherein, the source reference signal in this application refers to a signal used as a reference in the QCL relationship. For example, if the reference signal A and the reference signal B have a QCL relationship, and the large-scale characteristic corresponding to the reference signal A can be inferred from the large-scale characteristic corresponding to the reference signal B, the reference signal B is the source reference signal. Of course, in the cell format described above, the source reference signal can also be SSB.

For the convenience of description, this application uses different methods to describe different types of CSI-RS, mainly including the following three type:
(1)、CSI-RS for BM(CSI-RS for beam management):用于波束管理的CSI-RS,又称为CSI-RS for LI-RSRP,即用于层1参考信号接收功率(reference signal received power,RSRP) 测量的CSI-RS。(1), CSI-RS for BM (CSI-RS for beam management): CSI-RS for beam management, also known as CSI-RS for LI-RSRP, is used for layer 1 reference signal received power (reference signal received power, RSRP) measured CSI-RS.
其配置特征为:在该类型CSI-RS对应的CSI-RS资源集合的配置内,包括了repetition项配置,repetition项的值可以是On,也可以是Off,二者都表示该资源集合内的CSI-RS资源传输的CSI-RS的类型为CSI-RS for BM。在repetition项的值为On时,表示该资源集合内的CSI-RS资源使用相同的端口、相同的波束发送。Its configuration features are: in the configuration of the CSI-RS resource set corresponding to this type of CSI-RS, the repetition item configuration is included, and the value of the repetition item can be On or Off, both of which indicate the resources in the resource set. The type of CSI-RS transmitted by the CSI-RS resource is CSI-RS for BM. When the value of the repetition item is On, it indicates that the CSI-RS resources in the resource set are sent using the same port and the same beam.
(2)、CSI-RS for tracking:其为一个用于时频精同步的专用CSI-RS,该类CSI-RS也称为时频精同步参考信号(time/frequency tracking reference signal,TRS),其对应的CSI-RS资源称为TRS资源。(2), CSI-RS for tracking: it is a dedicated CSI-RS for precise time-frequency synchronization, this type of CSI-RS is also called time/frequency precise synchronization reference signal (time/frequency tracking reference signal, TRS), The corresponding CSI-RS resources are called TRS resources.
其配置特征为:在CSI-RS资源集合的配置内,包括TRS-info项配置,其值为True时,表示该CSI-RS资源集合用于时频精同步,或者说,表示该CSI-RS资源集合为TRS资源集合。Its configuration feature is: in the configuration of the CSI-RS resource set, including the TRS-info item configuration, when its value is True, it means that the CSI-RS resource set is used for time-frequency precise synchronization, or that the CSI-RS is used for precise synchronization. The resource set is a TRS resource set.
此外,TRS资源集合可以包括周期TRS资源集合和非周期TRS资源集合。周期TRS资源集合中包括4个周期TRS资源,在连续的两个时隙内发送,每个时隙包括两个TRS资源。非周期TRS资源集合中包括非周期TRS资源。TRS资源集合中的不同TRS资源对应的相同天线端口索引指示相同的天线端口。Also, the TRS resource set may include a periodic TRS resource set and an aperiodic TRS resource set. The periodic TRS resource set includes 4 periodic TRS resources, which are sent in two consecutive time slots, and each time slot includes two TRS resources. The aperiodic TRS resource set includes aperiodic TRS resources. The same antenna port index corresponding to different TRS resources in the TRS resource set indicates the same antenna port.
相应的,TRS包括周期TRS和非周期TRS,周期TRS可以理解为在周期TRS资源中传输的TRS,非周期TRS可以理解为在非周期TRS资源中传输的TRS。Correspondingly, TRS includes periodic TRS and aperiodic TRS. Periodic TRS can be understood as TRS transmitted in periodic TRS resources, and aperiodic TRS can be understood as TRS transmitted in aperiodic TRS resources.

The configuration feature is: in the configuration of the CSI-RS resource set, neither the repetition item nor the TRS-info item is included.
7、载波聚合(carrier aggregation,CA)、载波单元(component carrier,CC):7. Carrier aggregation (CA), carrier unit (component carrier, CC):
为了提供更高的业务速率,第三代合作伙伴计划(3rd generation partnership project,3GPP)在LTE-Advanced阶段提出下行1G比特每秒的要求,而受限于无线频谱资源紧缺等因素,运营商拥有的频谱资源都是非连续的,每个单一频段难以满足LTE-Advanced对带宽的需求。In order to provide higher service rates, the 3rd generation partnership project (3GPP) proposed a downlink 1Gbits per second requirement in the LTE-Advanced stage. However, due to factors such as the shortage of wireless spectrum resources, operators have The spectrum resources of LTE-Advanced are non-contiguous, and it is difficult for each single frequency band to meet the bandwidth requirements of LTE-Advanced.
基于上述原因,3GPP在版本10(release 10,R10)阶段引入了CA,通过将多个连续或非连续的载波聚合成更大的带宽,以满足LTE-Advanced对带宽的要求。其中,CA中的每个载波称为CC。Based on the above reasons, 3GPP introduced CA in the release 10 (release 10, R10) stage, by aggregating multiple contiguous or non-contiguous carriers into a larger bandwidth to meet the bandwidth requirements of LTE-Advanced. Among them, each carrier in the CA is called a CC.
8、部分带宽(bandwidth part,BWP):8. Bandwidth part (BWP):
为了实现网络侧和终端侧灵活的传输带宽配置,NR标准中提出BWP的概念。BWP是载波带宽(Carrier bandwidth)的一些子集。在CA场景下,一个CC可以被划分为多个BWP。In order to realize flexible transmission bandwidth configuration on the network side and the terminal side, the concept of BWP is proposed in the NR standard. BWP is some subset of carrier bandwidth. In the CA scenario, a CC can be divided into multiple BWPs.
在频域上,一个BWP中包括连续正整数个资源单元,比如包括连续正整数个子载波、资源块(resource block,RB)、或者资源块组(resource block group,RBG)。BWP可以是下行BWP或者上行BWP。其中,上行BWP用于终端向网络设备发送信号,下行BWP用于网络设备向终端发送信号。在本申请实施例中,正整数个资源单元可以是1个、2个、3个或者更多个,本申请实施例对此不做限制。In the frequency domain, a BWP includes a continuous positive integer number of resource units, such as a continuous positive integer number of subcarriers, resource blocks (resource blocks, RBs), or resource block groups (resource block groups, RBGs). The BWP may be a downstream BWP or an upstream BWP. The uplink BWP is used for the terminal to send a signal to the network device, and the downlink BWP is used for the network device to send a signal to the terminal. In the embodiment of the present application, the positive integer number of resource units may be one, two, three, or more, which is not limited in the embodiment of the present application.
终端可以配置有多个BWP,但同时只能激活一个。针对每个BWP,可以通过预配置或者网络设备向终端发送信令的方式,独立配置该BWP的参数集(numerology)。不同BWP的numerology可能相同,也可能不同。numerology可以通过但不限于以下参数信息中的一种或多种定义:子载波间隔,循环前缀(cyclic prefix,CP)、时间单位的信息、BWP的带宽等。例如,numerology可以由子载波间隔和CP来定义。A terminal can be configured with multiple BWPs, but only one can be active at the same time. For each BWP, a parameter set (numerology) of the BWP can be independently configured through pre-configuration or by means of the network device sending signaling to the terminal. The numerology of different BWPs may or may not be the same. The numerology can be defined by but not limited to one or more of the following parameter information: subcarrier spacing, cyclic prefix (CP), time unit information, bandwidth of BWP, and so on. For example, the numerology can be defined by subcarrier spacing and CP.
此外,CC的每个BWP上的每个PDSCH关联一个或多个TCI-state,用于指示该PDSCH的QCL信息,或者,每个BWP行的每个控制资源集合(control-resource set,CORESET)关联一个或多个TCI-state,用于指示该CORESET对应的PDCCH的QCL信息。In addition, each PDSCH on each BWP of the CC is associated with one or more TCI-states, which are used to indicate the QCL information of the PDSCH, or each control resource set (control-resource set, CORESET) of each BWP row One or more TCI-states are associated to indicate the QCL information of the PDCCH corresponding to the CORESET.
目前,网络设备可以为不同参考信号或信道分别指示不同的QCL关系,例如,通过TCI-state中的QCL信息为分别不同参考信号或信道配置不同的QCL关系,对于控制信道,网络设备在无线资源控制(radio resource control,RRC)信令中为每个CORESET配置一个或多个TCI-state索引,然后通过媒体接入控制控制元素(media access control control element,MAC CE)激活其中一个进行QCL指示。对于数据信道,网络设备在调度数据信道的下行控制信息(downlink control information,DCI)中动态指示数据信道的QCL关系。然而,为不同参考信号或信道分别指示QCL关系具有较大的信令时延,在移动性条件下该信令时延可能造成波束跟踪延迟较大,降低传输性能。Currently, the network device can indicate different QCL relationships for different reference signals or channels. For example, the QCL information in the TCI-state is used to configure different QCL relationships for different reference signals or channels. One or more TCI-state indexes are configured for each CORESET in the control (radio resource control, RRC) signaling, and then one of them is activated through the media access control control element (MAC CE) for QCL indication. For the data channel, the network device dynamically indicates the QCL relationship of the data channel in the downlink control information (DCI) of the scheduling data channel. However, indicating the QCL relationship for different reference signals or channels has a large signaling delay, which may cause a large beam tracking delay under mobility conditions and reduce transmission performance.
基于此,本申请提供一种准同位信息确定方法,该方法能够快速确定不同参考信号或信道的公共QCL信息,降低信令时延以及信令开销,从而提高传输性能。Based on this, the present application provides a method for determining quasi-co-location information, which can quickly determine common QCL information of different reference signals or channels, reduce signaling delay and signaling overhead, and improve transmission performance.

可选的,在上述两种情况下,第二信号可能关联第二TCI-state,也就是说,在第一种情况下,该第二TCI-state用于指示第一QCL关系,或者在第二种情况下该第二TCI-state用于指示第二QCL关系。此时,第二TCI-state已经被激活时(例如已经通过MAC CE激活了第二TCI-state),终端设备确定的第一QCL信息在第一时长后生效;或者,第二TCI-state未被激活时,终端设备确定的第一QCL信息在第二时长后生效。Optionally, in the above two cases, the second signal may be associated with the second TCI-state, that is, in the first case, the second TCI-state is used to indicate the first QCL relationship, or in the first In two cases, the second TCI-state is used to indicate the second QCL relationship. At this time, when the second TCI-state has been activated (for example, the second TCI-state has been activated through the MAC CE), the first QCL information determined by the terminal device takes effect after the first time period; or, the second TCI-state has not been activated. When activated, the first QCL information determined by the terminal device takes effect after the second time period.
其中,第一时长和第二时长的起始时刻相同,且第二时长大于第一时长。也就是说,在第二TCI-state未被激活时,第一QCL信息的生效时间要晚于第二TCI-state被激活时的生效时间。可选的,第一时长与第二时长的具体时间长度与终端设备能力有关。The start time of the first duration and the second duration are the same, and the second duration is greater than the first duration.

Exemplarily, the terminal device can use method 1 to determine the public QCL information whose QCL type is type D according to the index of the first signal, and use method 2 to determine the public QCL information of type D according to the index of the first signal. The index of a signal determines the QCL type is the common QCL information of type A. For example, when the first signal is the first SSB and the second signal is the TRS, the terminal device can determine that the first source reference signal of the common QCL information is the first SSB, the corresponding first QCL type is type D, and the terminal device can determine It is determined that the second source reference signal of the common QCL information is TRS, and the corresponding second QCL type is type A. Based on this, the SSB index can be used to indicate the beams of multiple channels or signals, and at the same time, the TRS can be determined according to the SSB, and the TRS can be used as the source reference signal of QCL type A to realize fast beam indication and time-frequency tracking.
或者,在方式三中第一TCI-state包括的QCL信息中不存在QCL类型为类型A的QCL信息时,终端设备可以采用方式二确定QCL类型为类型A的公共QCL信息。Alternatively, when there is no QCL information whose QCL type is Type A in the QCL information included in the first TCI-state in Mode 3, the terminal device may use Mode 2 to determine that the QCL type is Type A public QCL information.
