技术领域Technical field

本公开涉及无线通信领域但不限于无线通信领域，尤其涉及一种波束的功率控制方法、通信设备及存储介质。The present disclosure relates to the field of wireless communications, but is not limited to the field of wireless communications, and in particular, to a beam power control method, a communication device, and a storage medium.

背景技术Background technique

波束赋形通过定向的而非在三维空间内全向发送无线波，以波束的形式进行信息交互。波束实质上是无线信号构成的。接收端对无线信号的接收功率需要足够大，才能够保证接收端有足够的解码正确率，才能确保通信质量。故在发送波束之前，发送端需要计算出发射功率，以确保接收端的接收质量。Beamforming performs information exchange in the form of beams by directional, rather than omnidirectionally transmitting radio waves in three-dimensional space. The beam is essentially composed of wireless signals. The receiving end needs to have a large enough receiving power for the wireless signal to ensure that the receiving end has sufficient decoding accuracy to ensure communication quality. Therefore, before transmitting the beam, the transmitting end needs to calculate the transmitting power to ensure the receiving quality of the receiving end.

在现有技术中，通常基于接收端的目标接收功率及路径损耗等计算发送端的发送功率，可是具体应用时发现，即便采用这种方法，接收端依然存在很多接收质量差的问题，故如何进一步提升利用波束通信过程中，接收端的接收质量，以确保通信质量是需要进一步解决的问题。In the prior art, the transmission power of the transmitting end is usually calculated based on the target receiving power and the path loss of the receiving end. However, it is found in the specific application that even if this method is adopted, there are still many problems of poor reception quality at the receiving end, so how to further improve In the beam communication process, the receiving quality of the receiving end to ensure the communication quality is a problem that needs to be further solved.

具体实施方式Detailed ways

以下结合说明书附图及具体实施例对本公开的技术方案做进一步的详细阐述。The technical solutions of the present disclosure are further elaborated below in conjunction with the drawings and specific embodiments.

如图1A所示，本实施例提供一种波束的功率控制方法，应用于第一通信设备中，包括：As shown in FIG. 1A, the present embodiment provides a power control method for a beam, which is applied to a first communications device, and includes:

步骤S110：确定功率补偿偏移量，其中，所述功率补偿偏移量，用于针对波束进行功率补偿的功率调整量；Step S110: determining a power compensation offset, wherein the power compensation offset is used for power adjustment of power compensation for the beam;

步骤S120：根据至少一个所述功率补偿偏移量，计算波束的发射功率。Step S120: Calculate the transmit power of the beam according to at least one of the power compensation offsets.

如图1B所示，所述方法还包括：As shown in FIG. 1B, the method further includes:

步骤S130：根据所述发射功率发送波束。Step S130: Transmit a beam according to the transmit power.

在本实施例中，所述第一通信设备可为利用波束通信的通信双方中的任意一方。例如，通信设备是基站和用户设备(User Equipment，UE)，则所述第一通信设备可为UE。在另一些实施例中，所述第一通信设备和第二通信设备可均为UE，则所述第一通信设备可为发射波束的通信设备，第二通信设备为接收波束的设备。In this embodiment, the first communication device may be any one of two communication sides that utilize beam communication. For example, the communication device is a base station and a user equipment (User Equipment, UE), and the first communication device may be a UE. In other embodiments, the first communication device and the second communication device may both be UEs, then the first communication device may be a communication device that transmits a beam, and the second communication device is a device that receives a beam.

在无线通信过程中，波束之间可能存在相互干扰的问题，所述功率补偿偏移量可包括：针对波束干扰进行功率补偿的功率调整量，以提高当前用于两个通信设备之间通信的抗干扰能力，提高通信质量。In the process of wireless communication, there may be a problem of mutual interference between beams, and the power compensation offset may include: a power adjustment amount for power compensation for beam interference to improve communication currently used between two communication devices. Anti-interference ability, improve communication quality.

不同的波束采用的传输频率可能不同，则可能在相同或相近似的传输信道上的传输损耗也不同，在一些实施例中，所述功率补偿偏移量，还可包括：针对不同波束传输损耗的功率调整量。The transmission frequencies used by different beams may be different, and the transmission loss may be different on the same or similar transmission channels. In some embodiments, the power compensation offset may further include: transmission loss for different beams. The amount of power adjustment.

本公开实施例提供的波束的功率控制方法，在计算波束的发射功率之前，会考虑到不同波束使用过程中的特性，从而引入了计算不同波束的功率补偿偏移量，例如，可首先确定对干扰进行补偿的功率补偿偏移量，然后结合确定的功率补偿偏移量计算发射功率，然后利用计算得到的发射功率进行波束发送，这样的话，在进行波束的发送时，考虑到干扰对接收端的接收质量的干扰等不同波束的特性，从而可以确保接收端能够接收到目标接收功率，从而再次提升了通信质量。The power control method of the beam provided by the embodiment of the present disclosure considers the characteristics of different beam use processes before calculating the transmit power of the beam, thereby introducing a power compensation offset for calculating different beams. For example, the pair may be first determined. Interfering with the compensated power compensation offset, and then calculating the transmit power in combination with the determined power offset offset, and then using the calculated transmit power for beam transmission, so that when transmitting the beam, considering the interference to the receiving end The characteristics of different beams, such as the interference of the reception quality, can ensure that the receiving end can receive the target receiving power, thereby improving the communication quality again.

图2展示的不同波束收到的干扰程度。图2中横坐标为波束索引，纵坐标为干扰程度，不同的波束索引代表了不同的波束，故为了区分补偿每一个波束收到的干扰程度带来的不利影响，在步骤S110中通信设备会确定出发送波束的功率补偿偏移量。例如，这里的功率补偿偏移量是补偿波束的发射功率。例如，这里的波束干扰可波束之间的干扰，相同该小区内波束间干扰，不同小区之间的波束等。通过功率补偿偏移量，提升该波束的发射功率，从而可以抵消或抑制波束导致的接收端设备(即第二通信设备)接收并解调出波束的信号强度，从而确保波束的接收质量，以确保通信质量。Figure 2 shows the degree of interference received by the different beams. In Figure 2, the abscissa is the beam index, the ordinate is the degree of interference, and the different beam indices represent different beams. Therefore, in order to distinguish the adverse effects caused by the interference level received by each beam, the communication device will The power compensation offset of the transmit beam is determined. For example, the power offset offset here is the transmit power of the compensated beam. For example, the beam interference here may be interference between beams, the same inter-beam interference in the cell, the beam between different cells, and the like. The power compensation offset is used to improve the transmit power of the beam, so that the signal strength of the beam received by the receiving device (ie, the second communication device) caused by the beam can be cancelled or suppressed, thereby ensuring the beam receiving quality. Ensure communication quality.

图3所示的为一种基站和UE之间通过波束的信息交互方法。UE发送波束，基站采用与之对应的接收波束进行接收。FIG. 3 shows a method for information exchange between a base station and a UE through a beam. The UE transmits a beam, and the base station receives the received beam corresponding thereto.

图4显示的为不同波束对的波束干扰程度曲线，其中，不同的线性表示的不同的波束对；横轴表示的为：不在接收端的波束接收能量；纵轴表示的为：发生概率。Figure 4 shows the beam interference degree curves for different beam pairs, where different linear representations of different beam pairs; the horizontal axis represents: the beam is not receiving energy at the receiving end; the vertical axis represents: probability of occurrence.

在本实施例中，在计算发射功率时，所述功率补偿偏移量为自变量之一。不同的功率补偿偏移量，在发射功率的其他参数的保持一致的情况下，发射功率是不同的。再利用发射等于计算的发射功率的波束。这样的话，针对不同波束收到的干扰进行发射功率的补偿，从而使得接收端有更大的概率接收到目标功率的波束，从而确保了通信质量。In this embodiment, the power compensation offset is one of the independent variables when calculating the transmit power. Different power compensation offsets, the transmit power is different if the other parameters of the transmit power are consistent. A beam that transmits a transmit power equal to the calculated transmit power is reused. In this case, the transmission power is compensated for the interference received by different beams, so that the receiving end has a greater probability of receiving the beam of the target power, thereby ensuring the communication quality.

本实施例提供的波束的功率控制方法，可应用于任意一个频段，可选为适用于中高频频段，例如，适用于频率高于2GHz以上的无线频谱。The power control method of the beam provided in this embodiment can be applied to any frequency band, and can be applied to a medium-high frequency band, for example, to a wireless spectrum with a frequency higher than 2 GHz.

所述第一通信设备获取所述功率补偿偏移量的方式有多种，以下提供两种可选方式：There are various ways for the first communication device to obtain the power compensation offset. The following two options are provided:

方式一：method one:

所述步骤S110可包括：The step S110 may include:

接收所述第二通信设备发送的功率补偿偏移量。Receiving a power compensation offset sent by the second communication device.

若所述第二通信设备为基站等网络侧设备而所述第一通信设备为手机或物联网设备或车辆网设备等UE时，所述功率补偿偏移量，可以携带在各种下行信令或调度信息下发给UE，例如，通过无线资源控制(Radio Resource Control，RRC)信令、下行控制信息(Downlink Control Information，DCI)，或者，资源调度等信息直接向UE下发所述功率补偿偏移量。If the second communication device is a network side device such as a base station, and the first communication device is a UE such as a mobile phone or an Internet of Things device or a vehicle network device, the power compensation offset may be carried in various downlink signaling. Or the scheduling information is sent to the UE, for example, the power compensation is directly sent to the UE by using information such as radio resource control (RRC) signaling, downlink control information (DCI), or resource scheduling. Offset.

这样的话，所述UE在进行上行波束发送之前，会先从基站接收下发的功率补偿偏移量。在接收到功率补偿偏移量之后，再计算上行波束的发射功率，然后利用计算的发射功率向基站发送所述上行波束。In this case, the UE first receives the delivered power offset offset from the base station before performing the uplink beam transmission. After receiving the power offset offset, the transmit power of the uplink beam is calculated, and then the uplink beam is transmitted to the base station using the calculated transmit power.

方式二：Method 2:

如图5A所示，所述步骤S110可包括：As shown in FIG. 5A, the step S110 may include:

步骤S111：从第二通信设备接收查询索引；Step S111: Receive a query index from the second communication device.

步骤S112：根据所述查询索引查询所述功率补偿偏移量。Step S112: Query the power compensation offset according to the query index.

在本实施例中所述第一通信设备会预先从所述第二通信设备接收查询索引。然后在接收到查询索引之后，本地查询预先存储的查询索引与所述功率补偿偏移量的对应关系，从而获得与所述第二通信设备发送的查询索引对应的功率补偿偏移量。在步骤S120中基于查询的功率补偿偏移量计算所述发射功率。In this embodiment, the first communication device may receive a query index from the second communication device in advance. Then, after receiving the query index, the corresponding relationship between the pre-stored query index and the power compensation offset is locally queried, thereby obtaining a power compensation offset corresponding to the query index sent by the second communication device. The transmit power is calculated based on the power offset offset of the query in step S120.

在一些实施例中，所述步骤S111可包括：接收第二通信设备发送的偏移量索引；In some embodiments, the step S111 may include: receiving an offset index sent by the second communications device;

所述步骤S112可包括：以所述偏移量索引为查询索引，查询预先获取的功率补偿偏移量集合以获得所述功率补偿偏移量。The step S112 may include: querying the pre-acquired power compensation offset set to obtain the power compensation offset by using the offset index as a query index.

在本实施例中，所述第一通信设备预先存储有偏离量集合。功率补偿偏移量集合中包括多个与偏移量索引对应的功率补偿偏移量。In this embodiment, the first communication device stores in advance a set of deviation amounts. The power compensation offset set includes a plurality of power compensation offsets corresponding to the offset index.

例如，所述功率补偿偏移量集合中包括N个功率补偿偏移量，这些功率补偿偏移量依次排序，在本实施例中，所述偏移量索引可为对应的功率补偿偏移量在功率补偿偏移量集合中的序号。For example, the power compensation offset set includes N power compensation offsets, and the power compensation offsets are sequentially ordered. In this embodiment, the offset index may be a corresponding power compensation offset. The sequence number in the power compensation offset set.

所述第二通信设备可以通过(log ₂ ^N)向上取整个比特来指示所述偏移量索引。 The second communication device may indicate the offset index by taking the entire bit up (log ₂ ^N ).

在另一些实施例中，所述步骤S111可包括：接收第二通信设备发送的波束索引；In other embodiments, the step S111 may include: receiving a beam index sent by the second communications device;

所述步骤S112可包括：以所述波束索引为查询索引，查询预先获取的功率补偿偏移量集合，并获得所述功率补偿偏移量。The step S112 may include: querying the pre-acquired power compensation offset set with the beam index as a query index, and obtaining the power compensation offset.

在本实施例中所述第二通信设备直接发送的波束索引，通过波束索引的发送一方面可以指示第一通信设备发送的波束，同时在本实施例中所述波束索引还用于功率补偿偏移量的查询索引。In the embodiment, the beam index directly sent by the second communication device may be used to indicate the beam sent by the first communication device by using the beam index, and the beam index is also used for the power compensation bias in this embodiment. The index of the query for the shift.

在本实施例中，所述功率补偿偏移量集合中的功率补偿偏移量与波束索引具有对应关系，故在第一通信设备在接收到所述波束索引之后，以所述波束索引为查询依据查询预先存储的偏移量。In this embodiment, the power compensation offset in the power compensation offset set has a corresponding relationship with the beam index, so after the first communication device receives the beam index, the beam index is used as a query. The pre-stored offset based on the query.

在一些实施例中，所述查询索引是通过物理层信令发送的，具体如，所述步骤S111可包括：In some embodiments, the query index is sent by physical layer signaling. For example, the step S111 may include:

接收第二通信设备发送的携带有查询索引的物理层信令。Receiving physical layer signaling carried by the second communication device and carrying the query index.

所述物理层信令可为通信网络中处于最下层的信令，当所述第一通信设备为UE，所述第二通信设备为基站时，典型的所述物理层信令可为DCI。The physical layer signaling may be the lowest layer signaling in the communication network. When the first communication device is a UE and the second communication device is a base station, the typical physical layer signaling may be a DCI.

步骤S101：接收所述第二通信设备发送的所述功率补偿偏移量集合。Step S101: Receive the power compensation offset set sent by the second communications device.

例如，当所述第二通信设备为基站时，基站可以通过***消息等周期或非周期的下发所述功率补偿偏移量集合。这样的话，位于该基站形成的小区内的UE就可以接收到基站下发的功率补偿偏移量集合。For example, when the second communication device is a base station, the base station may send the power compensation offset set periodically or aperiodically through a system message or the like. In this case, the UE located in the cell formed by the base station can receive the power compensation offset set delivered by the base station.

在本实施例中，不同波束的功率补偿偏移量是基于长期观测各波束的干扰，并根据干扰的补偿效果统计确定的统计数据。In this embodiment, the power compensation offset of different beams is based on long-term observation of interference of each beam, and statistical data determined according to the compensation effect of the interference.

在本公开实施例中，所述步骤S101可具体包括：In the embodiment of the present disclosure, the step S101 may specifically include:

接收携带有所述功率补偿偏移量集合的高层信令；Receiving high layer signaling carrying the power compensation offset set;

所述高层信令可为非物理层(PHY)信令，例如，RRC信令、媒体访问控制(MAC)层信令等高于PHY层的MAC层、无线链路控制(RLC)层信令或分组数据汇聚(PDCP)层信令。The high layer signaling may be non-physical layer (PHY) signaling, for example, RRC signaling, media access control (MAC) layer signaling, etc., MAC layer higher than the PHY layer, and radio link control (RLC) layer signaling. Or Packet Data Convergence (PDCP) layer signaling.

通过高层信令携带所述功率补偿偏移量集合，从而不用利用额外的专用信令来发送所述功率补偿偏移量集合，从而具有现有技术兼容性强的特点。The power compensation offset set is carried by high layer signaling, so that the power compensation offset set is not transmitted by using additional dedicated signaling, thereby having the characteristics of strong compatibility of the prior art.

在一些实施例中，所述功率补偿偏移量集合及所述查询索引都可以是第二通信设备周期性发送的，此时，所述功率补偿偏移量集合的发送周期大于所述查询索引的发送周期。In some embodiments, the power compensation offset set and the query index may be periodically sent by the second communications device. In this case, the sending period of the power compensation offset set is greater than the query index. The sending cycle.

在另一些实施例中，所述功率补偿偏移量集合是周期下发的，所述查询索引是基于第一通信设备的请求发送的。In other embodiments, the power compensation offset set is issued periodically, and the query index is sent based on a request of the first communication device.

在还有一些实施例中，所述功率补偿偏移量集合及查询索引都是基于第一通信设备的请求发送的。In still other embodiments, the set of power compensation offsets and the query index are both sent based on a request by the first communication device.

所述功率补偿偏移量集合可以作为基站的按需请求的***信息块，根据UE的请求下发给UE。The power compensation offset set may be sent to the UE according to the request of the UE, as a system information block of the on-demand request of the base station.

在本实施例中将步骤S110中确定的所述功率补偿偏移量作为闭环功率控制参数，即将所述功率补偿偏移量作为自变量之一，计算闭环功率控制调整量。在本公开实施例中，利用闭环功率控制进行所述发射功率的计算。闭环功率控制，是一种发射端的发射功率根据接收端接收效果来动态调节的控制方式，这样的话，可以确保发射功率适用于不同时刻的无线环境，以进一步确保通信效果。In the embodiment, the power compensation offset determined in step S110 is used as a closed loop power control parameter, that is, the power compensation offset is used as one of the independent variables, and the closed loop power control adjustment amount is calculated. In the disclosed embodiment, the calculation of the transmit power is performed using closed loop power control. Closed-loop power control is a control method in which the transmitting power of the transmitting end is dynamically adjusted according to the receiving effect of the receiving end. In this way, the transmitting power can be ensured to be applicable to the wireless environment at different times to further ensure the communication effect.

在一些实施例中，所述步骤S120可采用如下函数计算所述发射功率：In some embodiments, the step S120 may calculate the transmit power by using the following function:

其中，P为所述发射功率；i为波束所使用的时间单元的序号；P _cmax(i)为所述第一通信设备的最大发射功率；P ₀为第二通信设备的目标接收功率；PL为传播损耗的补偿量；delta为所述功率补偿偏移量；M为所述波束使用的资源块数目；α为部分功率调整系数。 Where P is the transmit power; i is the sequence number of the time unit used by the beam; P _cmax (i) is the maximum transmit power of the first communication device; P ₀ is the target received power of the second communication device; The amount of compensation for the propagation loss; delta is the power compensation offset; M is the number of resource blocks used by the beam; and α is the partial power adjustment coefficient.

例如，所述查询索引可以为波束索引beam-index，也可以是偏移量索引，以下以beam-index为例，进一步提供几种计算所述delta的可选公式：For example, the query index may be a beam index beam-index or an offset index. The beam-index is taken as an example to further provide several alternative formulas for calculating the delta:

deltaTF _beam-index(i)+f(i) _beam-index； deltaTF _beam-index (i)+f(i) _beam-index ;

deltaTF _beam-index(i)+f(i)； deltaTF _beam-index (i)+f(i);

故在一些实施例中，计算所述发射功率的公式可包括以下至少之一：Therefore, in some embodiments, the formula for calculating the transmit power may include at least one of the following:

P为所述发射功率；i为波束所使用的时间单元的序号；P _cmax(i)为所述第一通信设备的最大发射功率；P ₀为第二通信设备的目标接收功率；PL为传播损耗的补偿量；delta为所述功率补偿偏移量；M为所述波束使用的资源块数目；α为部分功率调整系数。 P is the transmit power; i is the sequence number of the time unit used by the beam; P _cmax (i) is the maximum transmit power of the first communication device; P ₀ is the target received power of the second communication device; PL is propagation The amount of compensation for loss; delta is the power compensation offset; M is the number of resource blocks used by the beam; and α is the partial power adjustment coefficient.

又例如，例如，第一通信设备可以利用如下函数关系，计算所述发射功率：For another example, for example, the first communications device can calculate the transmit power using a functional relationship as follows:

TXP＝P0+Pl_compensation+delta_tf+close_loop_fi；TXP=P0+Pl_compensation+delta_tf+close_loop_fi;

其中，TXP为波束的发射功率；P0为目标接收功率；PL_compensation为需要补偿的传播损耗；delta_tf为与传输格式相关的功率调整；close_loop_fi表示为闭环功率控制的部分；闭环功率控制采用close_loop_fi＝(offset_beam_index+delta_fi)的方式。offset_beam_index表示不同波束上使用的功率补偿偏移量；Delta_fi为基站根据上行数据传输的误码率等指标，进行参数的控制，在不同波束间采用相同的参数，并进行参数的累计。Delta_fi(i)＝f(i-1)+step(i-k)，其中，i表示当前时刻；step(i-k)表示的功率步长的函关系；i-k为接收到发送功率控制(TPC)命令的时刻，例如，所述i-k为接收到计算功率步长的TPC命令的时刻。上述公式也可以写成如下形式，Among them, TXP is the transmit power of the beam; P0 is the target received power; PL_compensation is the propagation loss that needs to be compensated; delta_tf is the power adjustment related to the transmission format; close_loop_fi is the part of closed-loop power control; closed-loop power control adopts close_loop_fi=(offset_beam_index +delta_fi) way. Offset_beam_index indicates the power compensation offset used on different beams; Delta_fi is the base station that controls the parameters according to the error rate of the uplink data transmission, uses the same parameters between different beams, and accumulates the parameters. Delta_fi(i)=f(i-1)+step(ik), where i represents the current time; the function of the power step represented by step (ik); ik is the time at which the transmit power control (TPC) command is received For example, the ik is the time at which the TPC command to calculate the power step is received. The above formula can also be written as follows.

TXP＝P0+Pl_compensation+delta_tf+offset_beam_index+delta_fi；TXP=P0+Pl_compensation+delta_tf+offset_beam_index+delta_fi;

在一些实施例中，Offset_beam_index可以是一个集合内的某一个参数offset{offset_beam_1，..，offset_beam_N}。该offset{}信息通过基站的长期统计获取。基站通过配置信息告知UE具体的集合信息，并根据另外的快速信令信息告知UE选用哪个具体的offset_beam_x。该快速信令信息可以是基站通过下行调度信令直接配置，比如UE的上行调度信息；也可以通过专门的信令告知第一通信设备。In some embodiments, Offset_beam_index may be one of the parameters offset{offset_beam_1, .., offset_beam_N} within a set. The offset{} information is obtained by long-term statistics of the base station. The base station informs the UE of the specific set information through the configuration information, and informs the UE of which specific offset_beam_x is selected according to the additional fast signaling information. The fast signaling information may be directly configured by the base station by using downlink scheduling signaling, such as uplink scheduling information of the UE. The first communication device may also be notified by special signaling.

图6所示的为基站和UE之间基于波束索引进行波干扰的功率补偿偏移量的波束交互。FIG. 6 is a beam interaction of a power compensation offset for performing wave interference based on a beam index between a base station and a UE.

如图7所示，本实施例提供一种波束的功率控制方法，应用于第二通信设备中，包括：As shown in FIG. 7, the embodiment provides a power control method for a beam, which is applied to a second communication device, and includes:

然后接收第一通信设备利用所述功率补偿偏移量计算的发射功率发送的波束。第一通信设备这样发送的波束，由于考虑到干扰情况，利用功率补偿偏移量进行干扰消耗补偿，从而可以确保第二通信设备的接收质量，具有接收效果好的特点。A beam transmitted by the first communication device using the transmit power calculated by the power compensated offset is then received.

在另一些实施例中查询所述功率补偿偏移量集合使用的索引，复用波束索引，这样的话可以减少索引的个数，不必要记录波束索引与偏移量索引的对应关系。In other embodiments, the index used by the power compensation offset set is queried, and the beam index is multiplexed, so that the number of indexes can be reduced, and the correspondence between the beam index and the offset index is unnecessary.

在一些实施例中，所述波束索引的下发还可以用于向第一通信设备指示向第二通信设备发送信息的波束；从而实现一条信令的两种指示作用，减少信令开销。In some embodiments, the issuance of the beam index may also be used to indicate to the first communication device a beam that transmits information to the second communication device; thereby implementing two indications of one signaling, reducing signaling overhead.

在一些实施例中，所述方法还包括：In some embodiments, the method further includes:

以下结合上述任意实施例提供几个具体示例：Several specific examples are provided below in connection with any of the above embodiments:

示例1：Example 1:

本申请提案，针对上述问题，提出一种高频多波束下的功率控制方法。The proposal of the present application proposes a power control method under high frequency multi-beam for the above problem.

终端根据如下方式计算上行的发射功率The terminal calculates the uplink transmit power according to the following manner.

其中，P0为目标接收功率；PL_compensation为需要补偿的传播损耗；delta_tf为与传输格式相关的功率调整；close_loop_fi表示为闭环功率控制的部分；闭环功率控制采用close_loop_fi＝(offset_beam_index+delta_fi)的方式；Where P0 is the target received power; PL_compensation is the propagation loss that needs to be compensated; delta_tf is the power adjustment related to the transmission format; close_loop_fi is the part of closed-loop power control; closed-loop power control is closed_loop_fi=(offset_beam_index+delta_fi);

公式也可以写成如下形式，The formula can also be written as follows,

其中，Delta_fi为基站根据上行数据传输的误码率等指标，进行参数的控制，在不同波束间采用相同的参数，并进行参数的累计。Delta_fi(i)＝f(i-1)+step(i-k)，其中K表示K个时间单位之前的TPC命令。Among them, Delta_fi is a base station that controls parameters according to indicators such as the bit error rate of uplink data transmission, uses the same parameters between different beams, and accumulates parameters. Delta_fi(i)=f(i-1)+step(i-k), where K represents a TPC command before K time units.

其中，offset_beam_index表示不同波束上使用的功率补偿偏移量。Offset_beam_index可以是一个集合内的某一个参数offset{offset_beam_1，..，offset_beam_N}。该offset{}信息通过基站的长期统计获取。基站通过配置信息告知UE具体的集合信息，并根据另外的快速信令信息告知UE选用哪个具体的offset_beam_x。该快死信令信息可以是基站通过下行调度信令直接配置，比如UE的上行调度信息；也可以通过专门的信令告知终端。Where offset_beam_index represents the power offset offset used on different beams. Offset_beam_index can be a parameter in the set offset{offset_beam_1,..,offset_beam_N}. The offset{} information is obtained by long-term statistics of the base station. The base station informs the UE of the specific set information through the configuration information, and informs the UE of which specific offset_beam_x is selected according to the additional fast signaling information. The fast-dead signaling information may be directly configured by the base station by using downlink scheduling signaling, such as uplink scheduling information of the UE, or may be notified to the terminal through dedicated signaling.

offset{}可以是基站在每个波束上接收的干扰能量，针对每个波束有不同的干扰水平。该参数根据基站在多波束上的统计得到。该offset{}可以通过长期信令告知终端。终端根据基站的下行控制信息中指示的后续上行要用的波束信息确定上行功率控制中需要考虑的干扰水平。而不同波束的干扰水平可以通过其他方式告知给UE。The offset{} may be the interference energy received by the base station on each beam, with different interference levels for each beam.

The terminal determines the interference level to be considered in the uplink power control according to the beam information to be used for the subsequent uplink indicated in the downlink control information of the base station. The interference levels of different beams can be informed to the UE by other means.

示例2：Example 2:

基站通过RRC信令配置一套针对不同波束接收的功率补偿偏移值offset{offset_1，..offset_N}。终端根据上行发送命令中指示的需要使用的基站接收波束的信息，比如标识(id)、资源位置、端口号等，在进行上行探测参考信号(SRS)或者物理上行共享信道(PUSCH)信息、物理上行链路控制信道(PUCCH)信息发送时，在发送功率中使用该波束对应的偏移值。基站也可以采用专门的信令告诉UE采用具体哪个偏移值，而不是随着基站下行调度信令进行传输。The base station configures a set of power compensation offset values offset{offset_1, ..offset_N} for different beam reception through RRC signaling. The terminal performs uplink sounding reference signal (SRS) or physical uplink shared channel (PUSCH) information and physical information according to the information of the base station receiving beam, such as the identifier (id), the resource location, and the port number, which are required to be used in the uplink sending command. When uplink control channel (PUCCH) information is transmitted, the offset value corresponding to the beam is used in the transmission power. The base station may also use special signaling to tell the UE which specific offset value to use instead of transmitting with the base station downlink scheduling signaling.

示例3：Example 3:

如示例2描述，其中这个offset可以是基站在每个波束上测量的得到的干扰参数。As described in Example 2, wherein this offset can be the resulting interference parameter measured by the base station on each beam.

示例4：Example 4:

如示例1、2描述，其中这个offset可以是基站在每个波束上测量的得到的干扰参数。在没有定义专门的offset集合的情况下，可以通过信令直接指示干扰的水平的方式进行补偿。比如，As described in Examples 1, 2, wherein this offset may be the resulting interference parameter measured by the base station on each beam. In the case where a special offset set is not defined, compensation can be performed in a manner that directly indicates the level of interference by signaling. such as,
