Description

功率控制方法及装置Power control method and device 技术领域Technical field
本发明涉及通信技术领域，尤其涉及一种功率控制方法及装置。The present invention relates to the field of communications technologies, and in particular, to a power control method and apparatus.
背景技术Background technique
通信***中，通常使用不同种类的参考信号来获取信道质量信息或者信道状态信息。例如，探测参考信号(Sounding Reference Signal,SRS)可以用于波束管理(Beam Management,BM)，还可以用于获取信道状态信息(Channel State Information,CSI)。其中，波束管理是指基站根据SRS的波束测量结果来为终端选择较优的发射波束或者为基站选择较优的接收波束；信道状态信息的获取是指基站根据接收的终端发送的SRS，来确定终端发送上行数据的信道状态，从而为终端选择上行传输的秩指示(Rank Indicator,RI)、预编码矩阵指示(Precoding Matrix Indicators,PMI)和信道质量指示(Channel Quality Indicator,CQI)等指示。In a communication system, different kinds of reference signals are usually used to acquire channel quality information or channel state information. For example, a Sounding Reference Signal (SRS) can be used for Beam Management (BM), and can also be used to acquire Channel State Information (CSI). The beam management means that the base station selects a better transmit beam for the terminal or selects a better receive beam for the base station according to the beam measurement result of the SRS. The acquisition of the channel state information refers to the base station determining according to the SRS sent by the received terminal. The terminal transmits the channel state of the uplink data, so as to select an indication of the uplink indication (Rank Indicator, RI), Precoding Matrix Indicators (PMI), and Channel Quality Indicator (CQI) for the uplink.
然而，终端在发送SRS、PUSCH等上行数据时，基于不同的参考信号发送目的，如，根据参考信号的发送是用于波束管理还是信道状态信息获取，将会有不同的参考信号发射功率设置。具体地，当参考信号用于波束管理时，其可采用与PUSCH不同的发射功率设置，而当此参考信号用于信道状态信息的获取时，其可采用与PUSCH相同的发射功率设置。因此，NR新场景下，如何基于不同的发送需求和目的设置参考信号和上行业务数据的发射功率是需要亟待解决的问题。However, when the terminal transmits uplink data such as SRS and PUSCH, it is based on different reference signal transmission purposes. For example, according to whether the transmission of the reference signal is for beam management or channel state information acquisition, there will be different reference signal transmission power settings. Specifically, when the reference signal is used for beam management, it can adopt a different transmit power setting than the PUSCH, and when this reference signal is used for acquisition of channel state information, it can adopt the same transmit power setting as the PUSCH. Therefore, in the new NR scenario, how to set the transmit power of the reference signal and the uplink service data based on different transmission requirements and purposes is a problem that needs to be solved urgently.
发明内容Summary of the invention
本发明实施例提供了一种功率控制方法及装置，有助于进行参考信号资源的功率控制。Embodiments of the present invention provide a power control method and apparatus, which are useful for performing power control of reference signal resources.
第一方面，本发明实施例提供了一种功率控制方法，该功率控制方法中，终端可以接收网络设备发送的第一指示信息，基于该第一指示信息，确定参考信号资源集合中多个参考信号资源的功率控制参数；基于所述多个参考信号资源的功率控制参数发送所述多个参考信号资源。可见，该功率控制方法可以基于网络设备发送的第一指示信息对各参考信号进行功率控制，该第一指示信息可以根据参考信号的发送目的，如，根据参考信号的发送是用于波束管理还是信道状态信息获取等，由基站确定，从而增加了参考信号的功率控制的灵活性。In a first aspect, an embodiment of the present invention provides a power control method, in which a terminal may receive first indication information sent by a network device, and determine multiple references in a reference signal resource set based on the first indication information. a power control parameter of the signal resource; transmitting the plurality of reference signal resources based on power control parameters of the plurality of reference signal resources. It can be seen that the power control method can perform power control on each reference signal based on the first indication information sent by the network device, where the first indication information can be used according to the transmission purpose of the reference signal, for example, whether the transmission according to the reference signal is used for beam management or Channel state information acquisition, etc., is determined by the base station, thereby increasing the flexibility of power control of the reference signal.
可选的，该多个参考信号资源用于获取信道状态信息CSI时，多个参考信号资源需要多套功率控制参数，因此，第一指示信息可以包括N套功率控制参数，该N套功率控制参数分别适用于多个参考信号资源。Optionally, when the multiple reference signal resources are used to obtain the channel state information CSI, multiple reference signal resources require multiple sets of power control parameters. Therefore, the first indication information may include N sets of power control parameters, and the N sets of power control parameters The parameters apply to multiple reference signal resources respectively.
由于参考信号的功率控制机制与物理上行共享信道PUSCH的功率控制机制相同，另外，两者的功率控制参数是有部分共用的，这些共用的功率控制参数可以一起通过高层信令通知给终端。但是，参考信号资源用于获取信道状态信息时，网络设备配置了N套功率控制参数，使得终端无法知道哪一套功率控制参数可以作为某次PUSCH传输的功率控制 参数。若单独将PUSCH的功率控制参数发送给终端的话，将会导致信令开销过大。Since the power control mechanism of the reference signal is the same as the power control mechanism of the physical uplink shared channel PUSCH, in addition, the power control parameters of the two are partially shared, and the shared power control parameters can be jointly notified to the terminal through high layer signaling. However, when the reference signal resource is used to obtain the channel state information, the network device configures N sets of power control parameters, so that the terminal cannot know which set of power control parameters can be used as the power control parameter of a certain PUSCH transmission. If the power control parameters of the PUSCH are separately sent to the terminal, the signaling overhead will be too large.
为了节省开销，网络设备配置的N套功率控制参数中，每套功率控制参数为参考信号资源和物理上行共享信道PUSCH共用的功率控制参数，N为正整数，同时，网络设备可以发送第二指示信息，来指示终端从这N套功率控制参数中为PUSCH选择一套功率控制参数。In order to save the cost, in the N sets of power control parameters configured by the network device, each set of power control parameters is a power control parameter shared by the reference signal resource and the physical uplink shared channel PUSCH, where N is a positive integer, and at the same time, the network device can send a second indication. Information to instruct the terminal to select a set of power control parameters for the PUSCH from the N sets of power control parameters.
也就是说，该功率控制方法还可以包括以下步骤：接收所述网络设备发送的第二指示信息；所述第二指示信息用于指示所述N套功率控制参数中的其中一套功率控制参数；基于所述第二指示信息，从所述N套功率控制参数中确定一套功率控制参数；基于该套功率控制参数发送所述PUSCH。所述第二指示信息是通过物理层信令进行通知的。可见，该实施方式采用第一指示信息和第二指示信息来通知PUSCH的功率控制参数的方式，比分别发送参考信号资源的功率控制参数以及PUSCH的功率控制参数相比，更能够节省信令开销。That is, the power control method may further include the steps of: receiving second indication information sent by the network device; the second indication information is used to indicate one of the N sets of power control parameters And determining, according to the second indication information, a set of power control parameters from the N sets of power control parameters; and transmitting the PUSCH based on the set of power control parameters. The second indication information is notified by physical layer signaling. It can be seen that the manner in which the first indication information and the second indication information are used to notify the power control parameters of the PUSCH is more effective than the power control parameters of the reference signal resources and the power control parameters of the PUSCH. .
可选的，第二指示信息可以为参考信号资源指示，相应的，终端基于第二指示信息从所述N套功率控制参数确定一套功率控制参数，包括：终端确定参考信号资源指示所指示的参考信号资源的编号；终端从所述N套功率控制参数中确定所述编号对应的一套功率控制参数，作为PUSCH的功率控制参数。可见，该实施方式使得参考信号资源指示(SRS Resource Indicator,SRI)不仅可以用于指示或辅助PUSCH传输所基于的预编码信息，还可以复用为指示终端如何选择发送PUSCH的功率控制参数，进一步节省了信令开销。其中，SRI指示为终端发送的多个参考信号资源中的其中一个参考信号资源的编号，SRI用于指示或辅助PUSCH传输所基于的预编码信息时，该预编码信息即为终端发送该编号的参考信号资源所使用的预编码信息。Optionally, the second indication information may be a reference signal resource indication, and correspondingly, the terminal determines, according to the second indication information, a set of power control parameters from the N sets of power control parameters, including: determining, by the terminal, the reference signal resource indication And determining, by the terminal, a set of power control parameters corresponding to the number from the N sets of power control parameters, as a power control parameter of the PUSCH. It can be seen that this embodiment enables the reference signal resource indicator (SRI) to be used not only to indicate or assist the precoding information on which the PUSCH transmission is based, but also to multiplex the power control parameters indicating how the terminal selects to transmit the PUSCH, further The signaling overhead is saved. The SRI indicates the number of one of the plurality of reference signal resources sent by the terminal, and the SRI is used to indicate or assist the precoding information on which the PUSCH transmission is based, where the precoding information is sent by the terminal. The precoding information used by the reference signal resource.
可选的，参考信号资源用于波束管理时，较优的终端发射波束或者网络设备接收波束是根据针对参考信号资源的信道质量测量结果或波束质量测量结果来选择进行上行数据传输的功率设置。为了避免该影响，当基于该参考信号资源用于波束管理时，参考信号资源集合中每个参考信号资源应采用相同的功率控制参数(此时，SRS资源所采用的功率控制参数与PUSCH的功率控制参数无关)。但由于终端针对不同波束对应的不同路径所测量的路径损失值是不同的，为了避免上述由于各参考信号资源或各波束对应的功率不同导致波束选择不准的因素的影响，可选地，可将各参考信号资源采用的一个公共路径损失值设置为各波束公共的路径损失值方式来实现。Optionally, when the reference signal resource is used for beam management, the preferred terminal transmit beam or the network device receive beam is selected according to a channel quality measurement result or a beam quality measurement result for the reference signal resource to select a power setting for performing uplink data transmission. In order to avoid the impact, when the reference signal resource is used for beam management, each reference signal resource in the reference signal resource set should adopt the same power control parameter (at this time, the power control parameter used by the SRS resource and the power of the PUSCH) Control parameters are irrelevant). However, since the path loss values measured by the terminal for different paths corresponding to different beams are different, in order to avoid the above-mentioned factors that cause beam selection inaccuracy due to different reference signal resources or powers corresponding to the beams, optionally, The common path loss value adopted by each reference signal resource is set to a path loss value common to each beam.
也就是说，该功率控制方法还可以包括：接收所述网络设备发送的第三指示信息，所述第三指示信息用于指示该公共路径损失值的计算规则；基于所述路径损失值的计算规则，确定所述多个参考信号资源的功率控制参数中的路径损失值，该路径损失值为适用于所述多个参考信号资源的路径损失值。可见，该实施方式可以保证波束选择是基于相同的总发射功率进行的，从而，提高了波束选择的准确度。That is, the power control method may further include: receiving third indication information sent by the network device, where the third indication information is used to indicate a calculation rule of the common path loss value; and calculating based on the path loss value a rule that determines a path loss value in a power control parameter of the plurality of reference signal resources, the path loss value being a path loss value applicable to the plurality of reference signal resources. It can be seen that this embodiment can ensure that the beam selection is performed based on the same total transmission power, thereby improving the accuracy of beam selection.
其中，计算规则包括利用所述多个参考信号的路径损失测量值的平均值作为所述多个参考信号的路径损失值，和/或选择所述多个参考信号的路径损失测量值中的最大值作为所述多个参考信号的路径损失值。Wherein the calculation rule includes using an average value of the path loss measurement values of the plurality of reference signals as a path loss value of the plurality of reference signals, and/or selecting a maximum of the path loss measurement values of the plurality of reference signals The value is the path loss value of the plurality of reference signals.
其中，所述第三指示信息是通过高层信令和/或物理层信令进行通知的。The third indication information is notified by high layer signaling and/or physical layer signaling.
其中，所述第一指示信息是通过高层信令进行通知的，所述高层信令包括无线资源控制RRC信令。所述第二指示信息是通过物理层信令进行通知的。The first indication information is notified by high layer signaling, and the high layer signaling includes radio resource control RRC signaling. The second indication information is notified by physical layer signaling.
第二方面，本发明实施例还提供了一种功率控制方法，该功率控制方法从网络设备侧进行描述，该功率控制方法可以包括：网络设备向终端发送第一指示信息；接收所述终端基于所述第一指示信息确定的功率控制参数而发送的多个参考信号资源。可见，终端对参考信号资源进行功率控制是根据网络设备发送的第一指示信息来确定的。In a second aspect, the embodiment of the present invention further provides a power control method, which is described from a network device side, where the power control method may include: the network device sends first indication information to the terminal; The plurality of reference signal resources sent by the first indication information determining power control parameters. It can be seen that the power control of the reference signal resource by the terminal is determined according to the first indication information sent by the network device.
可选的，该多个参考信号资源用于获取信道状态信息CSI时，多个参考信号资源需要多套功率控制参数，因此，第一指示信息可以包括N套功率控制参数，该N套功率控制参数分别适用于多个参考信号资源。Optionally, when the multiple reference signal resources are used to obtain the channel state information CSI, multiple reference signal resources require multiple sets of power control parameters. Therefore, the first indication information may include N sets of power control parameters, and the N sets of power control parameters The parameters apply to multiple reference signal resources respectively.
由于参考信号的功率控制机制与物理上行共享信道PUSCH的功率控制机制相同，另外，两者的功率控制参数是有部分共用的，这些共用的功率控制参数可以一起通过高层信令通知给终端。但是，参考信号资源用于获取信道状态信息时，网络设备配置了N套功率控制参数，使得终端无法知道哪一套功率控制参数可以作为某次PUSCH传输的功率控制参数。若单独将PUSCH的功率控制参数发送给终端的话，将会导致信令开销过大。Since the power control mechanism of the reference signal is the same as the power control mechanism of the physical uplink shared channel PUSCH, in addition, the power control parameters of the two are partially shared, and the shared power control parameters can be jointly notified to the terminal through high layer signaling. However, when the reference signal resource is used to obtain the channel state information, the network device configures N sets of power control parameters, so that the terminal cannot know which set of power control parameters can be used as the power control parameter of a certain PUSCH transmission. If the power control parameters of the PUSCH are separately sent to the terminal, the signaling overhead will be too large.
为了节省开销，网络设备配置的N套功率控制参数中，每套功率控制参数为参考信号资源和物理上行共享信道PUSCH共用的功率控制参数，N为正整数，同时，网络设备可以向终端发送第二指示信息，所述第二指示信息用于指示所述N套功率控制参数中的其中一套功率控制参数；接收所述终端基于所述第二指示信息确定的功率控制参数而发送的PUSCH。所述第二指示信息是通过物理层信令进行通知的。可见，该实施方式中，网络设备采用第一指示信息和第二指示信息来通知PUSCH的功率控制参数的方式，比分别发送参考信号资源的功率控制参数以及PUSCH的功率控制参数相比，更能够节省信令开销。In order to save the cost, in the N sets of power control parameters configured by the network device, each set of power control parameters is a power control parameter shared by the reference signal resource and the physical uplink shared channel PUSCH, where N is a positive integer, and at the same time, the network device may send the first to the terminal. The second indication information is used to indicate one of the N sets of power control parameters, and the PUSCH sent by the terminal according to the power control parameter determined by the second indication information. The second indication information is notified by physical layer signaling. It can be seen that, in this implementation manner, the network device uses the first indication information and the second indication information to notify the power control parameter of the PUSCH, which is more capable than the power control parameter of the reference signal resource and the power control parameter of the PUSCH. Save signaling overhead.
可选的，第二指示信息为参考信号资源指示，所述参考信号资源指示用于所述终端从所述N套功率控制参数中确定一套功率控制参数。可见，该实施方式使得参考信号资源指示(SRS Resource Indicator,SRI)不仅可以用于指示或辅助PUSCH传输所基于的预编码信息，还可以复用为指示终端如何选择发送PUSCH的功率控制参数，进一步节省了信令开销。其中，SRI指示为终端发送的多个参考信号资源中的其中一个参考信号资源的编号，SRI用于指示或辅助PUSCH传输所基于的预编码信息时，该预编码信息即为终端发送该编号的参考信号资源所使用的预编码信息。Optionally, the second indication information is a reference signal resource indication, where the reference signal resource indicates that the terminal determines a set of power control parameters from the N sets of power control parameters. It can be seen that this embodiment enables the reference signal resource indicator (SRI) to be used not only to indicate or assist the precoding information on which the PUSCH transmission is based, but also to multiplex the power control parameters indicating how the terminal selects to transmit the PUSCH, further The signaling overhead is saved. The SRI indicates the number of one of the plurality of reference signal resources sent by the terminal, and the SRI is used to indicate or assist the precoding information on which the PUSCH transmission is based, where the precoding information is sent by the terminal. The precoding information used by the reference signal resource.
可选的，参考信号用于波束管理时，该功率控制方法还可以包括：向所述终端发送第三指示信息；所述第三指示信息用于指示所述多个参考信号资源的功率控制参数中路径损失值的计算规则，基于所述计算规则确定的路径损失值适用于所述多个参考信号资源。可见，该实施方式可以保证波束选择是基于相同的总发射功率进行的，从而，提高了波束选择的准确度。Optionally, when the reference signal is used for beam management, the power control method may further include: sending third indication information to the terminal; the third indication information is used to indicate power control parameters of the multiple reference signal resources. The calculation rule of the medium path loss value, the path loss value determined based on the calculation rule is applicable to the plurality of reference signal resources. It can be seen that this embodiment can ensure that the beam selection is performed based on the same total transmission power, thereby improving the accuracy of beam selection.
其中，该计算规则包括利用所述多个参考信号的路径损失测量值的平均值作为所述多个参考信号的路径损失值，和/或选择所述多个参考信号的路径损失测量值中的最大值作为所述多个参考信号的路径损失值。Wherein the calculation rule includes using an average value of the path loss measurement values of the plurality of reference signals as a path loss value of the plurality of reference signals, and/or selecting a path loss measurement value of the plurality of reference signals The maximum value is the path loss value of the plurality of reference signals.

其中，网络设备和终端之间通常使用不同种类的参考信号，用于获取信道质量或者信道状态信息。例如，探测参考信号(Sounding Reference Signal,SRS)可以用于波束管理(Beam  Management,BM)，还可以用于获取信道状态信息(Channel State Information,CSI)。Different types of reference signals are generally used between the network device and the terminal for acquiring channel quality or channel state information. For example, a Sounding Reference Signal (SRS) can be used for Beam Management (BM), and can also be used to acquire Channel State Information (CSI).

As a result, the transmission of the uplink data is performed. The uplink data generally includes a physical uplink shared channel (PUSCH), a physical uplink control channel (PUSCH), and an uplink reference signal resource.
其中，终端在发送参考信号时，需要确定总发射功率，即对该参考信号进行功率控制，功率控制是在对网络设备的接收信号强度或信噪比等指标进行评估的基础上，适时改变发射功率来补偿无线信道中的路径损耗和衰落，从而既维持了通信质量，又不会对同一无线资源中其他用户产生额外干扰。When the terminal sends the reference signal, it needs to determine the total transmit power, that is, the power control of the reference signal. The power control is based on the evaluation of the received signal strength or the signal-to-noise ratio of the network device, and the transmission is changed in time. Power compensates for path loss and fading in the wireless channel, thereby maintaining communication quality without causing additional interference to other users in the same radio resource.
因此，为了确定该参考信号的总发射功率，本发明实施例提供了一种功率控制方法、装置及终端，有助于进行功率控制。Therefore, in order to determine the total transmit power of the reference signal, the embodiment of the present invention provides a power control method, device, and terminal, which are helpful for power control.
请参阅图2，图2是本发明实施例提供的一种功率控制方法的流程示意图。其中，该功率控制方法可以包括以下步骤：Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of a power control method according to an embodiment of the present invention. The power control method may include the following steps:
S101、终端接收网络设备发送的第一指示信息；S101. The terminal receives the first indication information sent by the network device.
S102、终端基于该第一指示信息，确定参考信号资源集合中多个参考信号资源的功率控制参数；S102. The terminal determines, according to the first indication information, a power control parameter of multiple reference signal resources in the reference signal resource set.
S103、终端基于该多个参考信号资源的功率控制参数发送该多个参考信号资源。S103. The terminal sends the multiple reference signal resources based on power control parameters of the multiple reference signal resources.
其中，步骤S103中，终端基于所述每个参考信号资源的功率控制参数发送所述每个参考信号资源可以包括：终端基于每个参考信号资源的功率控制参数以及如下公式(2)所示功率控制机制来确定各参考信号的总发射功率；基于该总发射功率来发送各参考信号。The sending, by the terminal, the each reference signal resource based on the power control parameter of each reference signal resource may include: the power control parameter of the terminal based on each reference signal resource and the power represented by the following formula (2) A control mechanism is used to determine a total transmit power of each reference signal; each reference signal is transmitted based on the total transmit power.
其中，第一指示信息是通过高层信令进行通知的，所述高层信令包括无线资源控制RRC信令The first indication information is notified by high layer signaling, where the high layer signaling includes radio resource control RRC signaling.
可见，图2所示的功率控制方法可以基于网络设备发送的第一指示信息对各参考信号进行功率控制。It can be seen that the power control method shown in FIG. 2 can perform power control on each reference signal based on the first indication information sent by the network device.
由于参考信号的功率控制机制与物理上行共享信道PUSCH的功率控制机制相同，另外，两者的功率控制参数是有部分共用的，这些共用的功率控制参数可以一起通过高层信令通知给终端，例如，无线资源控制(Radio Resource Control，RRC)信令。对于另外一部分不共用的功率控制参数则可以分别通过高层信令或物理层信令通知给用户用于SRS或PUSCH的发射功率设置，如通过DCI信令进行通知。Since the power control mechanism of the reference signal is the same as the power control mechanism of the physical uplink shared channel PUSCH, in addition, the power control parameters of the two are partially shared, and the shared power control parameters may be jointly notified to the terminal through high layer signaling, for example, , Radio Resource Control (RRC) signaling. For other power control parameters that are not shared, the transmit power settings for the SRS or PUSCH may be notified to the user through high layer signaling or physical layer signaling, for example, by DCI signaling.
例如，PUSCH的功率控制机制对应的发射总功率可以采用如下公式(1)进行设置，For example, the total transmit power corresponding to the power control mechanism of the PUSCH can be set by using the following formula (1).

这里，P CMAX,c(i)表征终端在主服务小区载波c上的总发射功率,与PUSCH功率控制发送总功率中相同； Here, P CMAX,c (i) characterizes the total transmit power of the terminal on the primary serving cell carrier c, which is the same as in the PUSCH power control transmit total power;

M SRS表征SRS调度资源块数目，单位为PRB； M SRS characterizes the number of SRS scheduling resource blocks, and the unit is PRB;

例如，SRS的总发射功率采用上述公式(2)来设置，PUSCH的总发射功率采用上述公式(1)来设置时，网络设备通过高层信令通知的SRS和PUSCH可以共用的每套功率控制参数就可以包括P O_PUSCH,c(j)，α c(j)，PL c和f c(i)等参数。 For example, the total transmit power of the SRS is set by using the above formula (2). When the total transmit power of the PUSCH is set by the above formula (1), each set of power control parameters that the network device can use by the SRS and the PUSCH notified by the high layer signaling is shared. Parameters such as P O_PUSCH, c (j), α c (j), PL c and f c (i) may be included.
其中，SRS特有的功率控制参数包括P SRS_OFFSET和M SRS，而PUSCH特有的功率控制参 数包括M PUSCH,c(i)和Δ TF,c(i)。 Among them, the SRS-specific power control parameters include P SRS_OFFSET and M SRS , and the PUSCH-specific power control parameters include M PUSCH, c (i) and Δ TF,c (i).
当参考信号资源用于获取CSI时，每个参考信号资源所对应的功率控制参数是不同的，因此，网络设备可以为该SRS资源集合中的M个SRS资源配置N套功率控制参数(其中，M>＝1，1<N<＝M)，第一指示信息可以包括N套功率控制参数，该N套功率控制参数为参考信号资源和物理上行共享信道PUSCH共用的功率控制参数，网络设备可以通过高层信令中的第一指示信息通知给终端该N套功率控制参数(PC parameter)，每套功率控制参数可以为参考信号资源和PUSCH共用。另一种实施方式中，可选地，基站为UE配置一个type B的SRS资源集合，一个SRS资源集合包括M个SRS资源，同时配置此SRS资源集合下的M个SRS资源对应的N套功率控制参数，这里1<＝N<＝M。每套功率控制参数对应一个QCL假设，这里的QCL假设定义为SRS与基站发送的下行RS，如信道状态信息参考信号(Channel State Information Reference Signal,简称：CSI-RS)之间的关联关系或相关性。如，这里的相关性可以为终端的SRS发射波束方向与终端接收CSI-RS时的接收波束方向一致或强相关。When the reference signal resource is used to acquire the CSI, the power control parameters corresponding to each reference signal resource are different. Therefore, the network device may configure, for the M SRS resources in the SRS resource set, N sets of power control parameters (where M>=1,1<N<=M), the first indication information may include N sets of power control parameters, where the N sets of power control parameters are power control parameters shared by the reference signal resource and the physical uplink shared channel PUSCH, and the network device may The N sets of power control parameters (PC parameters) are notified to the terminal by using the first indication information in the high layer signaling, and each set of power control parameters may be shared by the reference signal resource and the PUSCH. In another implementation manner, the base station configures a set B SRS resource set for the UE, and the SRS resource set includes the M SRS resources, and configures the N sets of power corresponding to the M SRS resources in the SRS resource set. Control parameters, where 1<=N<=M. Each set of power control parameters corresponds to a QCL hypothesis. The QCL hypothesis here is defined as the relationship between the SRS and the downlink RS sent by the base station, such as the channel state information reference signal (CSI-RS). Sex. For example, the correlation here may be that the SRS transmit beam direction of the terminal is consistent or strongly correlated with the receive beam direction when the terminal receives the CSI-RS.
如图3所示，图3为本发明实施例提供的一种N套功率控制参数的示意图，其中，参考信号资源集合中每个参考信号资源编号对应的功率控制参数与未来PUSCH传输可能采用的功率控制参数相同。As shown in FIG. 3, FIG. 3 is a schematic diagram of a N sets of power control parameters according to an embodiment of the present invention, where power control parameters corresponding to each reference signal resource number in a reference signal resource set are possible for future PUSCH transmission. The power control parameters are the same.
但是，虽然网络设备可以通过第一指示信息通知各参考信号资源的功率控制参数，但一次PUSCH的传输只需要一套功率控制参数，导致终端无法确定从上述N套功率控制参数选择哪一套功率控制参数用于当前的PUSCH发送。However, although the network device can notify the power control parameters of each reference signal resource by using the first indication information, only one set of power control parameters is needed for the transmission of the primary PUSCH, so that the terminal cannot determine which set of power is selected from the N sets of power control parameters. Control parameters are used for the current PUSCH transmission.
为了解决该问题，请参阅图4，图4是本发明实施例提供的另一种功率控制方法的流程示意图，其中，图4所述的功率控制方法能够进一步确定PUSCH的功率控制参数。具体的，图4所示的功率控制方法除了包括上述S101至S103外，还可以包括以下步骤：To solve this problem, please refer to FIG. 4. FIG. 4 is a schematic flowchart diagram of another power control method according to an embodiment of the present invention. The power control method described in FIG. 4 can further determine a power control parameter of a PUSCH. Specifically, the power control method shown in FIG. 4 may further include the following steps in addition to the foregoing S101 to S103:
S104、终端接收该网络设备发送的第二指示信息；S104. The terminal receives the second indication information sent by the network device.
S105、终端基于该第二指示信息，从该N套功率控制参数中确定一套功率控制参数；S105. The terminal determines, according to the second indication information, a set of power control parameters from the N sets of power control parameters.
S106、终端利用该套功率控制参数发送该PUSCH。S106. The terminal sends the PUSCH by using the set of power control parameters.
其中，终端利用该套功率控制参数发送该PUSCH可以包括：终端基于该套功率控制参数和上述公式(1)来确定该PUSCH的总发射功率；基于该总发射功率发送该PUSCH。The transmitting, by the terminal, the PUSCH by using the set of power control parameters may include: determining, by the terminal, the total transmit power of the PUSCH based on the set of power control parameters and the foregoing formula (1); and transmitting the PUSCH based on the total transmit power.
该第二指示信息可以通过物理层信令进行通知，该物理层信令可以为DCI信令。The second indication information may be notified by physical layer signaling, where the physical layer signaling may be DCI signaling.
可见，当网络设备为终端配置多套功率控制参数时，终端还可以基于第二指示信息从多套功率控制参数中选择一套功率控制参数来发送PUSCH，而不必将PUSCH所用的功率控制参数直接通知给终端，也就是说，采用第一指示信息和第二指示信息来通知PUSCH的功率控制参数的方式，比分别发送参考信号资源的功率控制参数以及PUSCH的功率控制参数相比，更能够节省信令开销。It can be seen that when the network device configures multiple sets of power control parameters for the terminal, the terminal may also select a set of power control parameters from multiple sets of power control parameters to send the PUSCH based on the second indication information, without directly using the power control parameters used by the PUSCH. Notifying the terminal, that is, the manner of notifying the power control parameters of the PUSCH by using the first indication information and the second indication information is more save than the power control parameters of the reference signal resources and the power control parameters of the PUSCH respectively. Signaling overhead.
作为一种可选的实施方式，该第二指示信息可以为参考信号资源指示，相应的，终端基于第二指示信息从所述N套功率控制参数确定一套功率控制参数，包括：As an optional implementation manner, the second indication information may be a reference signal resource indication, and correspondingly, the terminal determines, according to the second indication information, a set of power control parameters from the N sets of power control parameters, including:
终端确定参考信号资源指示所指示的参考信号资源的编号；Determining, by the terminal, a number of the reference signal resource indicated by the reference signal resource indication;
终端从所述N套功率控制参数中确定所述编号对应的一套功率控制参数，作为PUSCH的功率控制参数。The terminal determines, according to the N sets of power control parameters, a set of power control parameters corresponding to the number, as a power control parameter of the PUSCH.
可见，该实施方式使得参考信号资源指示(SRS Resource Indicator,SRI)不仅可以用于指示或辅助PUSCH传输所基于的预编码信息，还可以复用为指示终端如何选择发送PUSCH的功率控制参数，进一步节省了信令开销。其中，SRI指示为终端发送的多个参考信号资源中的其中一个参考信号资源的编号，SRI用于指示或辅助PUSCH传输所基于的预编码信息时，该预编码信息即为终端发送该编号的参考信号资源所使用的预编码信息。It can be seen that this embodiment enables the reference signal resource indicator (SRI) to be used not only to indicate or assist the precoding information on which the PUSCH transmission is based, but also to multiplex the power control parameters indicating how the terminal selects to transmit the PUSCH, further The signaling overhead is saved. The SRI indicates the number of one of the plurality of reference signal resources sent by the terminal, and the SRI is used to indicate or assist the precoding information on which the PUSCH transmission is based, where the precoding information is sent by the terminal. The precoding information used by the reference signal resource.
可选地，该第二指示信息也可以是SRI之外的一个单独DCI信令，如为了做干扰协调等，UE具体用于PUSCH的功控参数配置可以为次优或任意其他的RS资源对应的参数配置。Optionally, the second indication information may also be a single DCI signaling other than the SRI. For the interference coordination, the UE may specifically configure the power control parameter of the PUSCH to be suboptimal or any other RS resource. Parameter configuration.
由于参考信号资源用于波束管理时，较优的终端发射波束或者网络设备接收波束是根据针对参考信号资源的信道质量测量结果或波束质量测量结果来选择进行上行数据传输的功率设置。例如，根据参考信号接收功率(Reference Signal Received Power，RSRP)或信道状态信息(Channel State Information，CSI)，其中，该信道状态信息包括秩指示(Rank Indication，RI)、信道质量指示(Channel Quality Indication，CQI)和预编码矩阵指示(Precoding Matrix Indication，PMI)等中的至少一个。Since the reference signal resource is used for beam management, the preferred terminal transmit beam or the network device receive beam is a power setting that selects uplink data transmission based on channel quality measurements or beam quality measurements for the reference signal resource. For example, according to Reference Signal Received Power (RSRP) or Channel State Information (CSI), the channel state information includes a Rank Indication (RI) and a Channel Quality Indication (Channel Quality Indication). , CQI) and at least one of a Precoding Matrix Indication (PMI) or the like.
可选地，该波束质量测量结果还可以包括参考信号接收质量(Reference Signal Received Quality，RSRQ)等。Optionally, the beam quality measurement result may further include a Reference Signal Received Quality (RSRQ) or the like.
因此，当不同参考信号资源的总发射功率不同进而影响到上述参考信号的接收功率时，有可能会导致网络设备所选的终端发射波束或者网络设备接收波束并不是较优的。Therefore, when the total transmit power of different reference signal resources is different to affect the received power of the reference signal, the terminal transmit beam selected by the network device or the network device receive beam may not be superior.
例如，终端发送对应不同波束的多个参考信号资源时，某个波束对应的参考信号的总发射功率较大，这样，信道质量或波束测量结果中虽然该波束的RSRP最大，但由于该波束的总发射功率较大，使得该波束并不一定是较优的波束，也就是说，功率因素会对波束的选择造成影响。For example, when a terminal sends multiple reference signal resources corresponding to different beams, the total transmit power of the reference signal corresponding to a certain beam is larger, so that although the RSRP of the beam is the largest in the channel quality or beam measurement result, due to the beam The total transmit power is large, so that the beam is not necessarily a better beam, that is, the power factor affects the choice of the beam.
为了避免该影响，参考信号资源用于波束管理时，参考信号资源集合中每个参考信号资源采用相同的功率控制参数(此时，SRS资源所采用的功率控制参数与PUSCH的功率控制参数无关)，例如，各参考信号资源的功率控制参数统一通过公式(3)进行设置，To avoid this effect, when the reference signal resource is used for beam management, each reference signal resource in the reference signal resource set adopts the same power control parameter (in this case, the power control parameter adopted by the SRS resource is independent of the power control parameter of the PUSCH) For example, the power control parameters of each reference signal resource are uniformly set by formula (3),
Figure PCTCN2018091353-appb-000004
Figure PCTCN2018091353-appb-000004
相较于上述给出的SRS用于获取CSI时设置总发射功率的公式(2)而言，该公式(3)中，M SRS,c(i)表示SRS特定的调度资源块数目，单位为PRB；P O_SRS,c(i)表示SRS特定的终端目标接收功率；α SRS,c(i)表示SRS特定的路损补偿因子；f SRS,c(i)表示SRS特定的闭环功率调整量；PL c表示终端测量的路径损失值。 In the formula (3), M SRS,c (i) represents the number of SRS-specific scheduling resource blocks, in units of formula (2), where the SRS is used to obtain the total transmit power when acquiring CSI. PRB;P O_SRS,c (i) represents the SRS-specific terminal target received power; α SRS,c (i) represents the SRS-specific path loss compensation factor; f SRS,c (i) represents the SRS-specific closed-loop power adjustment amount; PL c represents the path loss value measured by the terminal.
但由于终端在不同波束下对应的所测量的路径损失值是不同的，为了避免上述功率因素的影响导致的波束选择不匹配问题，可将各参考信号资源采用的波束路径损失值设置为多个波束公共的方式来实现，具体的，请参阅图5，图5是本发明实施例提供的又一种功率控制方法的流程示意图，其中，图5所示的功率控制方法中步骤S501与图2所示的功率控制方法中的步骤S101相同，这里不再详述。However, since the measured path loss values of the terminal are different under different beams, in order to avoid the beam selection mismatch caused by the influence of the power factor, the beam path loss value used by each reference signal resource may be set to multiple. For details, refer to FIG. 5. FIG. 5 is a schematic flowchart of still another power control method according to an embodiment of the present invention, where step S501 and FIG. 2 in the power control method shown in FIG. Step S101 in the power control method shown is the same and will not be described in detail herein.
S502、终端基于第一指示信息，确定参考信号资源集合中多个参考信号资源的功率控制参数；S502. The terminal determines, according to the first indication information, a power control parameter of multiple reference signal resources in the reference signal resource set.
S503、终端接收网络设备发送的第三指示信息；S503. The terminal receives third indication information sent by the network device.
S504、终端基于第三指示信息，确定多个参考信号资源的功率控制中的路径损失值，该路径损失值适用于所述多个参考信号资源；S504. The terminal determines, according to the third indication information, a path loss value in power control of the multiple reference signal resources, where the path loss value is applicable to the multiple reference signal resources.
S505、终端根据该功率控制参数发送多个参考信号资源。S505. The terminal sends multiple reference signal resources according to the power control parameter.
其中，该功率控制参数是基于第一指示信息和第二指示信息来确定的。The power control parameter is determined based on the first indication information and the second indication information.
可见，当参考信号资源用于进行波束管理时，每个波束对应的参考信号资源的功率控制参数是相同的，且功率控制参数中的路径损失测量值是基于网络设备指示的计算方法来确定的，因此，可以保证该波束选择是基于多个波束的参考信号资源采用相同的总发射功率进行的，从而，提高了波束选择的准确度。It can be seen that when the reference signal resource is used for beam management, the power control parameters of the reference signal resources corresponding to each beam are the same, and the path loss measurement value in the power control parameter is determined based on a calculation method indicated by the network device. Therefore, it can be ensured that the beam selection is performed based on the reference signal resources of the plurality of beams using the same total transmission power, thereby improving the accuracy of beam selection.
请参阅图6，图6是本发明实施例提供的又一种功率控制方法的流程示意图，其中，图6所示的功率控制方法是从网络设备侧进行描述的，具体的，图6所示的功率控制方法可以包括以下步骤：Referring to FIG. 6, FIG. 6 is a schematic flowchart of still another power control method according to an embodiment of the present invention. The power control method shown in FIG. 6 is described from a network device side. Specifically, FIG. 6 is shown in FIG. The power control method can include the following steps:
S601、网络设备向终端发送第一指示信息；S601. The network device sends the first indication information to the terminal.
S602、网络设备接收终端基于第一指示信息确定的功率控制参数而发送的多个参考信号资源。S602. The network device receives a plurality of reference signal resources that are sent by the terminal according to the power control parameter determined by the first indication information.
可见，终端对参考信号资源进行功率控制是根据网络设备发送的第一指示信息来确定的。It can be seen that the power control of the reference signal resource by the terminal is determined according to the first indication information sent by the network device.
进一步的，由于参考信号的功率控制基于与PUSCH的功率控制机制相同，且两者的功率控制参数是有部分是共用的，因此传统上，网络设备通知终端相同的一套或多套功率控制参数，可以适用于发送参考信号和PUSCH，从而节省信令开销。Further, since the power control of the reference signal is based on the same power control mechanism as the PUSCH, and the power control parameters of the two are partially shared, the network device conventionally notifies the terminal of the same set or multiple sets of power control parameters. It can be applied to transmit reference signals and PUSCH, thereby saving signaling overhead.
但是，由于参考信号在用于CSI获取和波束管理时，可能需要多个参考信号资源，所以，网络设备需要为终端配置多套功率控制参数，而一次PUSCH的传输仅需要一套功率控制参数，导致上述同时通知SRS和PUSCH的功率控制参数的方法不可行。However, since the reference signal may need multiple reference signal resources when used for CSI acquisition and beam management, the network device needs to configure multiple sets of power control parameters for the terminal, and only one set of power control parameters is needed for the primary PUSCH transmission. The method of causing the above-mentioned power control parameters to simultaneously notify the SRS and the PUSCH is not feasible.
为了解决该问题，网络设备可以为SRS资源集合中的M个SRS资源配置N套功率控制参数(其中，M>＝1，1<N<＝M)，第一指示信息可以包括N套功率控制参数，该N套功率控制参数为参考信号资源和物理上行共享信道PUSCH共用的功率控制参数，另一种实施方式中，可选地，基站为UE配置一个type B的SRS资源集合，一个SRS资源集合包括M个SRS资源，同时配置此SRS资源集合下的M个SRS资源对应的N套功率控制参数，这里1<＝N<＝M.每套功率控制参数对应一个QCL假设，这里的QCL假设定义为SRS与基站发送的下行RS，如信道状态信息参考信号(Channel State Information Reference Signal,简称：CSI-RS)之间的关联关系或相关性。如，这里的相关性可以为终端的SRS 发射波束方向与终端接收CSI-RS时的接收波束方向一致或强相关。如图3所示，图3为本发明实施例提供的一种N套功率控制参数的示意图，其中，参考信号资源集合中每个参考信号资源编号对应的功率控制参数与每个PUSCH功率参数编号对应的功率控制参数相同。In order to solve the problem, the network device may configure N sets of power control parameters for the M SRS resources in the SRS resource set (where M>=1, 1<N<=M), and the first indication information may include N sets of power control. The parameter, the N sets of power control parameters are power control parameters shared by the reference signal resource and the physical uplink shared channel PUSCH. In another implementation manner, the base station optionally configures a type B SRS resource set and one SRS resource for the UE. The set includes M SRS resources, and configures N sets of power control parameters corresponding to M SRS resources under the SRS resource set, where 1<=N<=M. Each set of power control parameters corresponds to a QCL hypothesis, where the QCL hypothesis It is defined as the association or correlation between the SRS and the downlink RS sent by the base station, such as the Channel State Information Reference Signal (CSI-RS). For example, the correlation here may be that the SRS transmit beam direction of the terminal is consistent or strongly correlated with the receive beam direction when the terminal receives the CSI-RS. As shown in FIG. 3, FIG. 3 is a schematic diagram of a N sets of power control parameters according to an embodiment of the present invention, where a power control parameter corresponding to each reference signal resource number in a reference signal resource set and each PUSCH power parameter number are used. The corresponding power control parameters are the same.
这样，网络设备可以通过高层信令中的第一指示信息通知给终端该N套功率控制参数(PC parameter)，每套功率控制参数可以为参考信号资源和PUSCH共用，同时，通过第二指示信息进一步指示该N套功率控制参数哪一套为PUSCH使用。In this way, the network device can notify the terminal of the N sets of power control parameters (PC parameters) by using the first indication information in the high layer signaling, and each set of power control parameters can be shared by the reference signal resource and the PUSCH, and the second indication information is Further indicating which set of N sets of power control parameters is used by the PUSCH.
具体的，请参阅图7，图7是本发明实施例提供的又一种功率控制方法的流程示意图，该功率控制方法可以除包括上述S601-S602之外，还可以包括以下步骤：Specifically, please refer to FIG. 7. FIG. 7 is a schematic flowchart diagram of still another power control method according to an embodiment of the present invention. The power control method may include the following steps in addition to the foregoing S601-S602:
S603、网络设备向终端发送第二指示信息；S603. The network device sends the second indication information to the terminal.
S604、网络设备接收终端基于第二指示信息确定的功率控制参数而发送的PUSCH。S604. The network device receives the PUSCH sent by the terminal according to the power control parameter determined by the second indication information.
其中，第二指示信息用于指示N套功率控制参数中的其中一套功率控制参数，作为PUSCH的功率控制参数。The second indication information is used to indicate one of the N sets of power control parameters as the power control parameter of the PUSCH.
可见，该实施方式通过设置N套能够同时适用于参考信号资源和PUSCH的功率控制参数，再通过第二指示信息来指示其中一套作为PUSCH的功率控制参数，与分别向终端发送N套参考信号资源的功率控制参数和一套PUSCH的功率控制参数相比，可以节省信令开销。It can be seen that, by setting N sets of power control parameters that can be applied to both the reference signal resource and the PUSCH, the second indication information is used to indicate one set as the power control parameter of the PUSCH, and the N sets of reference signals are respectively sent to the terminal. The power control parameters of the resource can save signaling overhead compared to the power control parameters of a set of PUSCH.
进一步的，该第二指示信息可以为参考信号资源指示，相应的，终端基于第二指示信息从所述N套功率控制参数确定一套功率控制参数，包括：Further, the second indication information may be a reference signal resource indication, and correspondingly, the terminal determines a set of power control parameters from the N sets of power control parameters based on the second indication information, including:
终端确定参考信号资源指示所指示的参考信号资源的编号；Determining, by the terminal, a number of the reference signal resource indicated by the reference signal resource indication;
终端从所述N套功率控制参数中确定所述编号对应的一套功率控制参数，作为PUSCH的功率控制参数。The terminal determines, according to the N sets of power control parameters, a set of power control parameters corresponding to the number, as a power control parameter of the PUSCH.
可见，该实施方式使得参考信号资源指示(SRS Resource Indicator,SRI)不仅可以用于指示或辅助PUSCH传输所基于的预编码信息，还可以复用为指示终端如何选择发送PUSCH的功率控制参数，进一步节省了信令开销。其中，SRI指示为终端发送的多个参考信号资源中的其中一个参考信号资源的编号，SRI用于指示或辅助PUSCH传输所基于的预编码信息时，该预编码信息即为终端发送该编号的参考信号资源所使用的预编码信息。可选地，该第二指示信息也可以是SRI之外的一个单独DCI信令，如为了做干扰协调等，UE具体用于PUSCH的功控参数配置可以为次优或任意其他的RS资源对应的参数配置。It can be seen that this embodiment enables the reference signal resource indicator (SRI) to be used not only to indicate or assist the precoding information on which the PUSCH transmission is based, but also to multiplex the power control parameters indicating how the terminal selects to transmit the PUSCH, further The signaling overhead is saved. The SRI indicates the number of one of the plurality of reference signal resources sent by the terminal, and the SRI is used to indicate or assist the precoding information on which the PUSCH transmission is based, where the precoding information is sent by the terminal.

For the interference coordination, the UE may specifically configure the power control parameter of the PUSCH to be suboptimal or any other RS resource. Parameter configuration.
请参阅图8，图8是本发明实施例提供的又一种功率控制方法的流程示意图，该功率控制方法是从网络设备侧进行阐述的。当参考信号资源用于波束管理时，较优的终端发射波束或者基站接收波束是根据针对参考信号资源的信道质量测量结果或波束质量测量结果来选择进行上行数据传输的功率设置。，为了避免由于各波束发射功率不同导致的波束选择公平性受影响，当基于参考信号资源用于波束管理时，参考信号资源集合中每个参考信号资源采用相同的功率控制参数(此时，SRS资源所采用的功率控制参数与PUSCH的功率控制参数无关)，也就是说，第一指示信息中包括的用于参考信号资源集合中的M个参考信号资源的N套功率控制参数是相同的，当然，由于不同参考信号资源采用的波束不同，波束不同导致每个波束路径上的路径损耗值也不同，为了进一步的控制各参考信号资源的 总发射功率相同，网络设备可以设置M个参考信号资源采用统一的路径损失值，即该路径损失值为各波束公共的路径损失值。Please refer to FIG. 8. FIG. 8 is a schematic flowchart diagram of still another power control method according to an embodiment of the present invention. The power control method is described from a network device side. When the reference signal resource is used for beam management, the preferred terminal transmit beam or base station receive beam is a power setting that selects for uplink data transmission based on channel quality measurements or beam quality measurements for the reference signal resource. In order to avoid the beam selection fairness caused by the difference of the transmit power of each beam, when the reference signal resource is used for beam management, each reference signal resource in the reference signal resource set adopts the same power control parameter (in this case, SRS) The power control parameters used by the resources are independent of the power control parameters of the PUSCH, that is, the N sets of power control parameters included in the first indication information for the M reference signal resources in the reference signal resource set are the same. Certainly, because different reference signal resources use different beams, different path differences result in path loss values on each beam path. To further control the total transmit power of each reference signal resource is the same, the network device can set M reference signal resources. A uniform path loss value is used, that is, the path loss value is a common path loss value of each beam.
具体的，请参阅图8，该功率控制方法可以包括以下步骤：Specifically, referring to FIG. 8, the power control method may include the following steps:
S801、网络设备向终端发送第一指示信息；S801. The network device sends the first indication information to the terminal.
S802、网络设备向终端发送第三指示信息；S802. The network device sends third indication information to the terminal.
S803、网络设备接收终端基于第一指示信息和第三指示信息确定的功率控制参数而发送的多个参考信号资源。S803. The network device receives, by the network, a plurality of reference signal resources that are sent by the terminal according to the power control parameters determined by the first indication information and the third indication information.
即第三指示信息用于指示所述多个参考信号资源的功率控制参数中路径损失值的计算规则，基于所述计算规则确定的路径损失值适用于所述多个参考信号资源。That is, the third indication information is used to indicate a calculation rule of the path loss value in the power control parameters of the multiple reference signal resources, and the path loss value determined based on the calculation rule is applicable to the multiple reference signal resources.
其中，该计算规则包括利用所述多个参考信号的路径损失测量值的平均值作为所述多个参考信号的路径损失值，和/或选择所述多个参考信号的路径损失测量值的最大值作为所述多个参考信号的路径损失值。其中，该多个波束路径损失测量值即终端测量的多个波束上参考信号资源的路径损失值。Wherein the calculation rule includes using an average value of the path loss measurement values of the plurality of reference signals as a path loss value of the plurality of reference signals, and/or selecting a maximum path loss measurement value of the plurality of reference signals The value is the path loss value of the plurality of reference signals. The plurality of beam path loss measurement values, that is, the path loss values of the reference signal resources on the plurality of beams measured by the terminal.
其中，第三指示信息可以通过高层信令和/或物理层信令进行通知的。The third indication information may be notified by using high layer signaling and/or physical layer signaling.
可见，参考信号资源用于波束管理时，每个波束的功率控制参数是相同的，且功率控制参数中的路径损失测量值是基于网络设备指示的计算方法来确定的，因此，可以保证波束选择是基于相同的总发射功率进行的，从而，提高了波束选择的准确度。It can be seen that when the reference signal resource is used for beam management, the power control parameters of each beam are the same, and the path loss measurement value in the power control parameter is determined based on a calculation method indicated by the network device, so that beam selection can be ensured. It is based on the same total transmit power, thereby improving the accuracy of beam selection.
请参阅图9，图9是本发明实施例提供的一种功率控制装置的结构示意图，该功率控制装置可以采样上述图2至图5对应的功率控制方法，具体的，该功率控制装置可以包括以下单元：Referring to FIG. 9 , FIG. 9 is a schematic structural diagram of a power control apparatus according to an embodiment of the present invention. The power control apparatus may sample the power control method corresponding to FIG. 2 to FIG. 5 . Specifically, the power control apparatus may include The following units:
接收单元901，用于接收网络设备发送的第一指示信息；The receiving unit 901 is configured to receive first indication information sent by the network device.
确定单元902，用于基于所述第一指示信息，确定参考信号资源集合中多个参考信号资源的功率控制参数；The determining unit 902 is configured to determine, according to the first indication information, a power control parameter of multiple reference signal resources in the reference signal resource set;
发送单元903，用于基于所述多个参考信号资源的功率控制参数发送所述多个参考信号资源。The sending unit 903 is configured to send the multiple reference signal resources based on power control parameters of the multiple reference signal resources.
作为一种可选的实施方式，参考信号资源用于获取信道状态信息CSI时，多个参考信号资源需要多套功率控制参数，因此，第一指示信息可以包括N套功率控制参数，该N套功率控制参数分别适用于多个参考信号资源。其中，N为正整数。As an optional implementation, when the reference signal resource is used to obtain the channel state information CSI, multiple reference signal resources require multiple sets of power control parameters. Therefore, the first indication information may include N sets of power control parameters, and the N sets. The power control parameters are applicable to multiple reference signal resources, respectively. Where N is a positive integer.
由于参考信号的功率控制机制与物理上行共享信道PUSCH的功率控制机制相同，另外，两者的功率控制参数是有部分共用的，这些共用的功率控制参数可以一起通过高层信令通知给终端。但是，参考信号资源用于获取信道状态信息时，网络设备配置了N套功率控制参数，使得终端无法知道哪一套功率控制参数可以作为PUSCH的功率控制参数。若单独将PUSCH的功率控制参数发送给终端的话，将会导致信令开销过大。Since the power control mechanism of the reference signal is the same as the power control mechanism of the physical uplink shared channel PUSCH, in addition, the power control parameters of the two are partially shared, and the shared power control parameters can be jointly notified to the terminal through high layer signaling. However, when the reference signal resource is used to obtain channel state information, the network device configures N sets of power control parameters, so that the terminal cannot know which set of power control parameters can be used as the power control parameter of the PUSCH. If the power control parameters of the PUSCH are separately sent to the terminal, the signaling overhead will be too large.
为了节省开销，网络设备配置的N套功率控制参数中，每套功率控制参数为参考信号资源和物理上行共享信道PUSCH共用的功率控制参数，N为正整数，同时，网络设备可以发送第二指示信息，来指示终端从这N套功率控制参数中为PUSCH选择一套功率控制参 数。In order to save the cost, in the N sets of power control parameters configured by the network device, each set of power control parameters is a power control parameter shared by the reference signal resource and the physical uplink shared channel PUSCH, where N is a positive integer, and at the same time, the network device can send a second indication. Information to instruct the terminal to select a set of power control parameters for the PUSCH from the N sets of power control parameters.
也就是说，该功率控制装置中，接收单元901还可以接收所述网络设备发送的第二指示信息；所述第二指示信息用于指示所述N套功率控制参数中的其中一套功率控制参数；确定单元902，还用于基于所述第二指示信息，从所述N套功率控制参数中确定一套功率控制参数；发送单元903可以基于该套功率控制参数发送所述PUSCH。可见，该实施方式采用第一指示信息和第二指示信息来通知PUSCH的功率控制参数的方式，比分别发送参考信号资源的功率控制参数以及PUSCH的功率控制参数相比，更能够节省信令开销。That is, in the power control apparatus, the receiving unit 901 may further receive second indication information sent by the network device, where the second indication information is used to indicate one of the N sets of power control parameters. The determining unit 902 is further configured to determine a set of power control parameters from the N sets of power control parameters based on the second indication information; the sending unit 903 may send the PUSCH based on the set of power control parameters. It can be seen that the manner in which the first indication information and the second indication information are used to notify the power control parameters of the PUSCH is more effective than the power control parameters of the reference signal resources and the power control parameters of the PUSCH. .
其中，第二指示信息可以为参考信号资源指示，相应的，确定单元902基于第二指示信息从所述N套功率控制参数确定一套功率控制参数，可以为：确定单元902确定参考信号资源指示所指示的参考信号资源的编号；确定单元902从所述N套功率控制参数中确定所述编号对应的一套功率控制参数，作为PUSCH的功率控制参数。可见，该实施方式使得参考信号资源指示(SRS Resource Indicator,SRI)不仅可以用于指示PUSCH传输所基于的预编码信息，还可以复用为指示终端如何选择发送PUSCH的功率控制参数，进一步节省了信令开销。The second indication information may be a reference signal resource indication. Correspondingly, the determining unit 902 determines a set of power control parameters from the N sets of power control parameters based on the second indication information, where the determining unit 902 determines the reference signal resource indication. a number of the indicated reference signal resource; the determining unit 902 determines, from the N sets of power control parameters, a set of power control parameters corresponding to the number, as a power control parameter of the PUSCH. It can be seen that this embodiment enables the reference signal resource indicator (SRI) to be used not only to indicate the precoding information on which the PUSCH transmission is based, but also to multiplex the power control parameters indicating how the terminal selects to transmit the PUSCH, further saving Signaling overhead.
其中，SRI指示为终端发送的多个参考信号资源中的其中一个参考信号资源的编号，SRI用于指示PUSCH传输所基于的预编码信息时，该预编码信息即为终端发送该编号的参考信号资源所使用的预编码信息。The SRI indicates the number of one of the plurality of reference signal resources sent by the terminal, and the SRI is used to indicate the precoding information on which the PUSCH transmission is based, where the precoding information is the reference signal for the terminal to send the number. The precoding information used by the resource.
可选地，该第二指示信息也可以是SRI之外的一个单独DCI信令，如为了做干扰协调等，UE具体用于PUSCH的功控参数配置可以为次优或任意其他的RS资源对应的参数配置。Optionally, the second indication information may also be a single DCI signaling other than the SRI. For the interference coordination, the UE may specifically configure the power control parameter of the PUSCH to be suboptimal or any other RS resource. Parameter configuration.
作为另一种可选的实施方式，参考信号资源用于波束管理时，较优的终端发射波束或者网络设备接收波束是根据针对参考信号资源的信道质量测量结果或波束质量测量结果来选择进行上行数据传输的功率设置。为了避免该影响，参考信号资源用于波束管理时，参考信号资源集合中每个参考信号资源采用相同的功率控制参数(此时，SRS资源所采用的功率控制参数与PUSCH的功率控制参数无关)。但由于终端针对不同波束对应的不同路径所测量的路径损失值是不同的，为了避免上述功率因素的影响导致的波束选择不匹配的问题，可将各参考信号资源采用的波束中路径损失值设置为多个波束公共的方式来实现。As another optional implementation manner, when the reference signal resource is used for beam management, the preferred terminal transmit beam or the network device receive beam is selected according to channel quality measurement result or beam quality measurement result for the reference signal resource. Power setting for data transmission. To avoid this effect, when the reference signal resource is used for beam management, each reference signal resource in the reference signal resource set adopts the same power control parameter (in this case, the power control parameter adopted by the SRS resource is independent of the power control parameter of the PUSCH) . However, since the path loss values measured by the terminal for different paths corresponding to different beams are different, in order to avoid the problem of beam selection mismatch caused by the influence of the above power factors, the path loss value in the beam used by each reference signal resource may be set. It is implemented in a way that multiple beams are common.
因此，接收单元901，还用于接收所述网络设备发送的第三指示信息，所述第三指示信息用于指示路径损失值的计算规则；确定单元902，还用于基于所述路径损失值的计算规则，确定所述多个参考信号资源的功率控制参数中的路径损失值，该路径损失值适用于所述多个参考信号资源。Therefore, the receiving unit 901 is further configured to receive third indication information that is sent by the network device, where the third indication information is used to indicate a calculation rule of the path loss value, and the determining unit 902 is further configured to use the path loss value. a calculation rule that determines a path loss value in a power control parameter of the plurality of reference signal resources, the path loss value being applicable to the plurality of reference signal resources.
其中，该计算规则包括利用多个参考信号的路径损失测量值的平均值作为该多个参考信号的路径损失值，和/或选择多个参考信号的路径损失测量值的最大值作为该多个参考信号的路径损失值。Wherein the calculation rule includes using an average value of the path loss measurement values of the plurality of reference signals as a path loss value of the plurality of reference signals, and/or selecting a maximum value of the path loss measurement values of the plurality of reference signals as the plurality of The path loss value of the reference signal.
其中，第三指示信息是通过高层信令和/或物理层信令进行通知的。The third indication information is notified by using high layer signaling and/or physical layer signaling.
其中，第一指示信息是通过高层信令进行通知的，所述高层信令包括无线资源控制RRC信令。The first indication information is notified by high layer signaling, and the high layer signaling includes radio resource control RRC signaling.
可见，该实施方式可以保证波束选择是基于相同的总发射功率进行的，从而，提高了波束选择的准确度。It can be seen that this embodiment can ensure that the beam selection is performed based on the same total transmission power, thereby improving the accuracy of beam selection.
