Description

一种功率控制方法及相关设备Power control method and related equipment

技术领域Technical field

本申请涉及无线网络技术领域，尤其涉及一种功率控制方法及相关设备。The present application relates to the field of wireless network technologies, and in particular, to a power control method and related equipment.

背景技术Background technique

在毫米波***中，一个重要的限制就是在毫米波发射节点或低功率的无线接入节点(small cell)、与用户设备(User Equipment，UE)之间的通信链路很容易受到移动物体的阻碍，用户转向或UE朝向改变时链路更容易发生链路失败，为了解决上述问题，可以采用超密集网络部署和波束赋形(beamforming)的方式，在链路质量变差时切换服务波束，从而保障毫米波的通信质量。因此在更高频率(远大于6GHz)中，一个小区所在的区域可以由多个窄的高增益波束(beam)覆盖。不同beam的波束覆盖可以发生变化，例如波束宽度不同，以向整个小区区域中的公共控制信道提供稳定的覆盖。Beam的个数可能从几十到几百，不仅覆盖水平方向，也覆盖垂直方向。In the millimeter wave system, an important limitation is that the communication link between the millimeter wave transmitting node or the low power wireless access node (Small cell) and the user equipment (User Equipment, UE) is easily affected by the moving object. Obstruction, the link is more prone to link failure when the user turns or the UE changes direction. In order to solve the above problem, the ultra-dense network deployment and the beamforming method can be used to switch the service beam when the link quality is deteriorated. Thereby ensuring the communication quality of millimeter waves. Thus at higher frequencies (far greater than 6 GHz), the area in which one cell is located can be covered by multiple narrow high gain beams. Beam coverage of different beams may vary, such as different beamwidths, to provide stable coverage to common control channels throughout the cell area. The number of beams may range from tens to hundreds, covering both the horizontal and vertical directions.

在高频***中存在如下几种情况：(1)如图1所示，当UE在beam中、或beam之间移动时，波束赋形的增益跟随UE位置改变而改变。由于beam中心处的波束赋形的增益很大，在UE移动到beam边缘时，链路质量改变很大。因此，在UE移动(尤其高速移动)情况下，要求上行(Uplink，UL)功率控制机制跟踪上行链路质量的范围。(2)如图2(A)所示，由于UE体积小且重量轻，更容易进行旋转，上行beam可能随着UE旋转而频繁改变。UE旋转对beam方向有很大影响，在短时间内引起上行波束赋形的增益的改变。又如2(B)所示，高功率节点以46dBm发送，低功率节点只以30dBm发送。当UE移动时，UE可能从高发送功率节点改变为低发送功率节点，beam和对应的波束赋形的增益发生改变。在以上两种情况下，由于beam切换，上行链路质量可能快速改变，要求上行功率控制机制跟随上行链路质量的改变率。(3)当在UE使用波束赋形时，由于支持的天线个数不同，波束形式(beam pattern)也不同。UE使用的beam pattern不同，对相邻小区会产生干扰也不同。如果UE的beam较窄，则对相邻小区的干扰很小；如果UE使用全向天线或使用的beam较宽，则对相邻小区的干扰很大。因此，要求上行功率控制机制考虑UE波束赋形的形式。There are several cases in the high frequency system: (1) As shown in FIG. 1, when the UE moves in the beam, or between the beams, the gain of the beamforming changes following the UE position change. Since the gain of beamforming at the center of the beam is large, the link quality changes greatly as the UE moves to the edge of the beam. Therefore, in the case of UE mobility (especially high speed mobility), an uplink (UL) power control mechanism is required to track the range of uplink quality. (2) As shown in FIG. 2(A), since the UE is small in size and light in weight, it is easier to rotate, and the up-beam may change frequently as the UE rotates. The UE rotation has a large influence on the beam direction, causing a change in the gain of the uplink beamforming in a short time. As shown in 2(B), the high power node is transmitted at 46 dBm, and the low power node is transmitted at only 30 dBm. When the UE moves, the UE may change from a high transmit power node to a low transmit power node, and the gain of the beam and corresponding beamforming changes. In both cases, the uplink quality may change rapidly due to beam switching, requiring the uplink power control mechanism to follow the rate of change of the uplink quality. (3) When the UE uses beamforming, the beam pattern is different because the number of supported antennas is different. The beam pattern used by the UE is different, and the interference to the neighboring cells is also different. If the beam of the UE is narrow, the interference to the neighboring cell is small; if the UE uses the omnidirectional antenna or the beam used is wider, the interference to the neighboring cell is large. Therefore, the uplink power control mechanism is required to take into account the form of UE beamforming.

综上所述，为了保证上行链路的质量，需要指定UE波束的功率控制参数，而如果分别对每个波束进行配置，势必增加***开销。In summary, in order to ensure the quality of the uplink, it is necessary to specify the power control parameters of the UE beam, and if each beam is configured separately, the system overhead is inevitably increased.

可选的，所述第一指示消息还包含所述功率控制参数相关的资源，所述功率控制参数相关的资源为时域资源、频域资源以及空间域资源中的至少一种。Optionally, the first indication message further includes a resource related to the power control parameter, where the resource related to the power control parameter is at least one of a time domain resource, a frequency domain resource, and a spatial domain resource.

具体的，当***应用动态时分双工(Time Division Duplex，TDD)或灵活双工时，对于某个波束或波束对，在资源分配时存在时域资源/频域资源/空间域资源中至少一种。其中，频域资源以频域资源单位进行划分，频域资源单位包括频带、子带以及物理资源块(physical resource block，PRB)中的至少一种。时域资源以时域资源单位进行划分，时域资源单位包括超帧、帧、时隙、子帧、微子帧、微时隙、正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号以及少于一个OFDM符号中的至少一种。空间域资源以空间域资源单位进行划分，空间域资源单位包括波束、波束对以及天线端口中的至少一种。在对波束进行分组的同时也需要对多个资源进行分组。Specifically, when the system applies dynamic time division duplex (TDD) or flexible duplex, at least one of time domain resource/frequency domain resource/space domain resource exists in resource allocation for a certain beam or beam pair. Kind. The frequency domain resource is divided into frequency domain resource units, and the frequency domain resource unit includes at least one of a frequency band, a subband, and a physical resource block (PRB). Time domain resources are divided into time domain resource units including superframes, frames, time slots, subframes, micro subframes, minislots, and Orthogonal Frequency Division Multiplexing (OFDM) symbols. And at least one of less than one OFDM symbol. The spatial domain resource is divided into spatial domain resource units, and the spatial domain resource unit includes at least one of a beam, a beam pair, and an antenna port. It is also necessary to group multiple resources while grouping beams.

进一步的，可以在相同传输方向的资源上根据链路损耗和/或主要干扰进行分组。例如，针对发送和接收点(Transmission and Reception Point，TRP1)、TRP2、TRP3，在时域资源和频域资源上对于某个波束的传输方向依次为U-U-U、U-U-D以及U-D-D，其中，U表示上行方向、D表示下行方向。在对资源进行分组时应该考虑U-U-U干扰类型波束组，U-U-D干扰类型波束组以及U-D-D干扰类型波束组。对于某一个TRP，只有干扰类型相同时才进行资源分组。其中，干扰类型由相邻TRP在资源上的传输方向确定。Further, grouping can be performed on the same transmission direction resources according to link loss and/or primary interference. For example, for the transmission and reception point (TRP1), TRP2, and TRP3, the transmission direction of a certain beam on the time domain resource and the frequency domain resource is UUU, UUD, and UDD, wherein U represents the uplink direction. D indicates the downstream direction. U-U-U interference type beam sets, U-U-D interference type beam sets, and U-D-D interference type beam sets should be considered when grouping resources. For a TRP, resource grouping is performed only when the interference types are the same. The interference type is determined by the transmission direction of the neighboring TRP on the resource.

可选的，所述网络设备可以根据传输内容和/或传输信道，配置所述波束的所述功率控制参数。Optionally, the network device may configure the power control parameter of the beam according to the transmission content and/or the transmission channel.

具体的，在每个波束组或波束对组中，不同的传输内容或传输信道可能占用不同波束宽度和/或使用不同的参考信号的波束，因此需要根据传输内容或传输信道来配置功率控制参数。例如，控制信道通常会采用较宽的波束，以实现覆盖，保证传输稳健，并减少***开销。而数据信道通常会采用较窄的波束，以提升数据传输的吞吐量等。因此，在每个波束组或波束对组中，对于数据信道和控制信道，需要设定不同的功率控制参数。即使对于PUCCH和PRACH两种不同控制信道，也可以设定不同的功率控制参数。又如，对于不同的传输内容，如果针对的是超可靠及低延迟通讯(Ultra-reliable and Low Latency Communications，URLLC)传输，那么设定的功率控制参数需要区别于通常的超宽带传输eMBB。对于每个组，对于不同的内容传输或信道传输，可以设定不同的功率控制参数。或者对于每个组，对于不同的内容传输或信道传输，有多种或多系列功率控制参数。Specifically, in each beam group or group of beam pairs, different transmission content or transmission channels may occupy different beam widths and/or beams using different reference signals, so it is necessary to configure power control parameters according to transmission content or transmission channels. . For example, the control channel typically uses a wider beam to achieve coverage, ensure robust transmission, and reduce system overhead. The data channel usually uses a narrower beam to improve the throughput of data transmission. Therefore, in each beam group or group of beam pairs, different power control parameters need to be set for the data channel and the control channel. Different power control parameters can be set even for two different control channels, PUCCH and PRACH. For another example, for different transmission contents, if it is for Ultra-reliable and Low Latency Communications (URLLC) transmission, the set power control parameters need to be distinguished from the usual ultra-wideband transmission eMBB. For each group, different power control parameters can be set for different content transmissions or channel transmissions. Or for each group, there are multiple or multiple series of power control parameters for different content transmissions or channel transmissions.

另外，功率控制参数是分层的，由小区特定的值、beam特定的值和UE特定的值任意至少一种组合而成。其中，小区特定的值主要基于对第一参考信号的检测及推导出的链路损耗而得到，可以是扇区波束特定的或宽波束特定的。Beam特定的值主要基于第二参考信号检测及推导出的链路损耗而得到，可以包括TRP侧的接收波束赋形的增益和/或TRP侧的发送波束赋形的增益。Beam特定的值可以是一个波束组特定的或一组波束特定的。UE特定的值主要基于对第二参考信号的检测及推导出的链路损耗而得到，可以包括UE侧的发送波束赋形的增益和/或UE侧的接收波束赋形的增益。其中，第一参考信号是小区特定的参考信号(Reference Signal，RS)，例如DRS(discovery RS)、SS (synchronization signal)、non-UE-specific下行参考信号(Downlink Reference Signal，DL RS)或其它long-term DL RS。第二参考信号是UE特定的RS，例如非周期RS(由UE触发或网络触发)。In addition, the power control parameters are hierarchical, and are combined by at least one of a cell-specific value, a beam-specific value, and a UE-specific value. The cell-specific value is mainly based on the detection of the first reference signal and the derived link loss, and may be sector beam-specific or wide-beam-specific. The Beam-specific value is mainly obtained based on the link loss detected and derived by the second reference signal, and may include the gain of the receive beamforming on the TRP side and/or the gain of the transmit beamforming on the TRP side. The Beam specific value can be a beam group specific or a group of beam specific. The UE-specific value is mainly obtained based on the detection of the second reference signal and the derived link loss, and may include the gain of the transmit beamforming on the UE side and/or the gain of the receive beamforming on the UE side. The first reference signal is a cell-specific reference signal (Reference Signal, RS), for example, DRS (discovery RS), SS (synchronization signal), non-UE-specific downlink reference signal (Downlink Reference Signal, DL RS) or other long-term DL RS. The second reference signal is a UE-specific RS, such as an aperiodic RS (triggered by the UE or triggered by the network).

因此，小区特定的值、beam特定的值和UE特定的值分别采用了不同的波束宽度和基于不同的参考信号进行检测，分别包含不同传输内容和/或不同传输信道，可以配置不同的功率控制参数。在考虑载波空间等因素时，根据不同的基带参数numerology而相应地设置不同的功率控制参数；在考虑业务类型(如eMBB、mMTC、URLLC等)时，根据传输内容而相应地设置不同的功率控制参数。Therefore, the cell-specific value, the beam-specific value, and the UE-specific value are respectively detected by using different beamwidths and based on different reference signals, respectively, including different transmission contents and/or different transmission channels, and different power control can be configured. parameter. When considering factors such as carrier space, different power control parameters are set according to different baseband parameters numerology; when considering service types (such as eMBB, mMTC, URLLC, etc.), different power control is set according to the transmission content. parameter.

可选的，所述波束组或所述波束对组对应资源上的当前资源的功率控制参数的数值为上一资源的功率控制参数的数值与预设调整值之和。其中，所述当前资源为当前子帧、当前OFDM符号、当前时隙、当前波束、当前天线端口以及当前物理资源块中的至少一项；所述上一资源为上一子帧、上一OFDM符号、上一时隙、上一波束、上一天线端口以及上一物理资源块中的对应的至少一项。Optionally, the value of the power control parameter of the current resource on the resource group or the pair of beam pairs is the sum of the value of the power control parameter of the previous resource and the preset adjustment value. The current resource is at least one of a current subframe, a current OFDM symbol, a current time slot, a current beam, a current antenna port, and a current physical resource block; the previous resource is a previous subframe and a previous OFDM. At least one of a symbol, a previous time slot, a previous beam, a previous antenna port, and a previous physical resource block.

具体的，当波束组或波束对组采用累积模式时，在某个波束上进行上行传输时，功率控制参数需要按照波束所属的波束组以及资源分配进行累积叠加。例如，当发射功率控制(Transmit Power Control，TPC)命令以绝对方式被包括在上行授权(UL grant)中时，功率控制参数f_c(i)＝f_c(i-1)+δ_PUSCH,c(i-K_PUSCH)。当TPC命令以相对方式被包括在UL grant中时，功率控制参数f_c(i)＝f_c(i-n)+δ_PUSCH,c(i-K_PUSCH)。i-n是波束组或波束对组对应的频段或子带或子帧的上一个子帧。又如，如果子帧类型1包括子帧0、子帧1、子帧5和子帧6，那么如果i＝5，则i-n＝1，子帧5的功率控制参数的值为子帧1控制控制参数的值与预设调整值之和Specifically, when the beam group or the beam pair group adopts the accumulation mode, when uplink transmission is performed on a certain beam, the power control parameter needs to be cumulatively superimposed according to the beam group to which the beam belongs and the resource allocation. For example, when a Transmit Power Control (TPC) command is included in an uplink grant (UL grant) in an absolute manner, the power control parameter f _c (i)=f _c (i-1)+δ _PUSCH,c (iK _PUSCH ). When the TPC command is included in the UL grant in a relative manner, the power control parameter f _c (i) = f _c (in) + δ _PUSCH,c (iK _PUSCH ). In is the previous sub-frame of the frequency band or sub-band or subframe corresponding to the beam group or beam pair group. For another example, if the subframe type 1 includes the subframe 0, the subframe 1, the subframe 5, and the subframe 6, if i=5, then in=1, the value of the power control parameter of the subframe 5 is the subframe 1 control control. The sum of the value of the parameter and the preset adjustment value

After receiving the first indication message, the terminal device applies the corresponding power control parameters of the beam group m on the carrier i, the subframe k, and the beam j belonging to the beam group m.
