Priority of the application, the entire contents of which are incorporated herein by reference. Technical field

本发明涉及通信领域，尤其涉及一种 PHR上报的方法及设备。背景技术 The present invention relates to the field of communications, and in particular, to a method and a device for reporting a PHR. Background technique

目前 LTE ( Long Time Evolution, 长期演进 ) R10版本中已经计划支持 UE( User Equipment,用户终端）的上行 PRB( Physical Resource Block, 物理资源块）不连续分配，包括在同一个载波上同时发送 PUCCH ( Physical Uplink Control Channel, 物理上行控制信道）和 PUSCH ( Physical Uplink Shared Channel, 物理上行共享信道）。引入这个机制后对现有的 PHR ( power headroom report, 功率裕量报告 ) 上报就会产生一定影响。当 UE采用非连续 PRB 进行发送时，由于带外辐射指标的限制，终端需要采用一定的功率回退，不能以本来的最大发送功率发送，而需要减少一部分功率。如图 1所示，当 UE以连续 PRB发送时，如图 1的 A部分所示，这时 UE可以以最大功率发送，比如 20dbm; 当 UE 以非连续 PRB 发送时，如图 1的 B部分所示，这时两个 PRB 的总发送功率并不能达到最大功率 20dbm, 需要减少，比如减少 3dbm, 这意味着 UE这时最大只能采用 17dbm发送。 Currently, the LTE (Long Time Evolution) R10 version has been planned to support the discontinuous allocation of the uplink (Physical Resource Block) of the UE (User Equipment), including transmitting the PUCCH on the same carrier at the same time. Physical Uplink Control Channel, and Physical Uplink Shared Channel (PUSCH). The introduction of this mechanism will have an impact on the existing PHR (power headroom report). When a UE uses a non-contiguous PRB to transmit, the terminal needs to use a certain power backoff due to the limitation of the outband radiation indicator, and cannot transmit at the original maximum transmit power, but needs to reduce a part of the power. As shown in FIG. 1, when the UE transmits in a continuous PRB, as shown in part A of FIG. 1, the UE can transmit at the maximum power, for example, 20 dbm; when the UE transmits in a non-contiguous PRB, as shown in part B of FIG. As shown, the total transmit power of the two PRBs does not reach the maximum power of 20dbm, which needs to be reduced, for example, by 3dbm. This means that the UE can only transmit at 17dbm at this time.

PHR机制是 UE向基站报告 UE发送功率和最大功率差的一种机制。 LTE的 R8/9***中， PHR的定义针对的是 PUSCH信道，也就是 PHR = Pcmax - P_PUSCH,其中 Pcmax是终端满足射频指标情况下能够允许的最大发射功率。在 LTE Rd-8中，由于上行只支持连续的资源分配，因此不同终端的最大功率回退差别很小，在 l-2dB左右。目前 PHR的 MAC CE设计中，如表 1所示，采用 LCID值为 11010 的标识。 The PHR mechanism is a mechanism in which the UE reports the UE transmission power and the maximum power difference to the base station. In the R8/9 system of LTE, the definition of PHR is for the PUSCH channel, that is, PHR = Pcmax - P _PUSCH , where Pcmax is the maximum transmit power that the terminal can allow if the terminal satisfies the radio frequency indicator. In LTE Rd-8, since the uplink only supports continuous resource allocation, the maximum power backoff difference of different terminals is small, about l-2dB. At present, in the MAC CE design of the PHR, as shown in Table 1, the identifier with the LCID value of 11010 is used.

表 1 Table 1

具体 MAC CE如表 2所示，前两个 bit为 R比特，为保留比特，后 6 个比特为指示 PHR的等级。

The specific MAC CE is shown in Table 2. The first two bits are R bits, which are reserved bits, and the last 6 bits are the level indicating PHR.

表 2 Table 2

R R PH Oct 1 现有技术中， PHR触发条件包括： R R PH Oct 1 In the prior art, the PHR trigger conditions include:

1、当上行新数据需要发送，并且 UE测的 Pathloss改变高于设定的门限，并且 prohibitPHR-timer超时，则触发 PHR; 1. When the uplink new data needs to be sent, and the Pathloss changed by the UE is higher than the set threshold, and the prohibitPHR-timer times out, the PHR is triggered;

2、当 periodicPHR-timer超时后触发 PHR; 2. The PHR is triggered when the periodicPHR-timer times out.

3、当 PHR 的参数进行重配时触发 PHR。 3. PHR is triggered when the parameters of the PHR are reconfigured.

在 LTE Rd-10及后续的***中，引入了多种上行传输组合，例如非连续 PRB的上行传输（包括 PUCCH与 PUSCH同时传输，非连续的 PUSCH 资源调度等）。对于上行传输的终端最大功率回退，一定程度上取决于终端的实现：不同终端在相同上行传输情况下的最大功率回退可能不同；同一个终端在不同的上行传输组合情况下（例如连续 PRB传输和非连续 PRB传输 )的最大功率回退也可能不同。该差异在一些情况下可能较大，例如 4-6dB, 或更多。如图 2所示，现有的 PHR上报机制并不能反映功率回退情况，基站无法获知 UE功率回退情况，由此导致基站不能对 UE进行合理的调度。发明内容 In LTE Rd-10 and subsequent systems, multiple uplink transmission combinations are introduced, such as uplink transmission of non-contiguous PRB (including PUCCH and PUSCH simultaneous transmission, non-contiguous PUSCH resource scheduling, etc.). For the uplink transmission, the maximum power backoff of the terminal, one To a certain extent, it depends on the implementation of the terminal: the maximum power backoff of different terminals in the same uplink transmission may be different; the maximum power of the same terminal in different uplink transmission combinations (such as continuous PRB transmission and discontinuous PRB transmission) The rollback may also be different. This difference may be large in some cases, such as 4-6 dB, or more. As shown in Figure 2, the existing PHR reporting mechanism does not reflect the power backoff. The base station cannot know the UE power backoff. As a result, the base station cannot perform reasonable scheduling on the UE. Summary of the invention

具体实施方式 detailed description

本发明实施例一提供一种 PHR上 >¾的方法，如图 3所示，包括：步骤 301 , 网络侧对用户终端进行非连续 PRB调度； A first embodiment of the present invention provides a method for performing a non-continuous PRB scheduling on a user terminal, as shown in FIG. 3, where the network side performs a non-continuous PRB scheduling on the user terminal.

步骤 302, 所述用户终端根据配置的 PHR上报策略向所述网络侧发送 PHR 艮告。 Step 302: The user terminal sends a PHR advertisement to the network side according to the configured PHR reporting policy.

所述 PHR上报策略由所述网络侧在向所述用户终端发送的调度信令中携带，和 /或所述用户终端自身配置。 The PHR reporting policy is carried by the network side in scheduling signaling sent to the user terminal, and/or the user terminal itself is configured.

所述用户终端根据配置的 PHR上报策略向所述网络侧发送 PHR 报告包括： The sending, by the user terminal, the PHR report to the network side according to the configured PHR reporting policy includes:

所述用户终端接收调度信令； The user terminal receives scheduling signaling;

所述 PHR上报策略中包括 PHR报告与 PHR触发信息之间的时序关系。 The PHR reporting policy includes a timing relationship between the PHR report and the PHR trigger information.

所述用户终端根据配置的 PHR上报策略向所述网络侧发送 PHR 报告包括： The user terminal sends a PHR to the network side according to the configured PHR reporting policy. The report includes:

所述用户终端在每次非连续 PRB 调度时向网络侧发送 PHR报告。 The user terminal sends a PHR report to the network side each time the discontinuous PRB scheduling is performed.

所述用户终端判断是否已经发送过当前非连续 PRB调度对应的 PHR报告； Determining, by the user terminal, whether a PHR report corresponding to the current discontinuous PRB scheduling has been sent;

如果判断结果为否，发送当前非连续 PRB 调度对应的 PHR报告。 If the judgment result is no, the PHR report corresponding to the current discontinuous PRB schedule is sent.

如果判断结果为是，所述用户终端根据所述 PHR触发信息向网络侧发送 PHR 艮告。 If the determination result is yes, the user terminal sends a PHR advertisement to the network side according to the PHR trigger information.

所述调度信令为 PDCCH ( Physical Downlink Control Channel,物理下行控制信道）信令或者 MAC ( Media Access Control, 媒体访问控制 ) CE ( Control Element, 控制单元 )信令。 The scheduling signaling is a PDCCH (Physical Downlink Control Channel) signaling or a MAC (Media Access Control) CE (Control Element) signaling.

需要说明的是，本实施例中步骤 301并非必要条件，当由于非连续 PRB调度之外的原因导致用户终端发生功率回退时，本实施例中用户终端根据配置的 PHR上报策略向所述网络侧发送 PHR报告的方法仍然适用。本发明实施例二提供一种 PHR上报的方法，如图 4所示，包括以下步骤： It should be noted that, in this embodiment, the step 301 is not a requirement. When the power back-off occurs in the user terminal due to the reason other than the non-contiguous PRB scheduling, the user terminal sends the policy to the network according to the configured PHR reporting policy. The method of sending PHR reports on the side still applies. A second embodiment of the present invention provides a method for reporting a PHR, as shown in FIG. 4, including The following steps:

步骤 401 ,基站向 UE发送携带 PHR trigger信息的 PDCCH信令。具体的， PHR trigger信息可以设置在现有的 PDCCH format格式中的空闲 bit, 也可以设置为在现有 DCI format的基础上增加 PHR trigger (触发）信息，或者定义一个包含 PHR trigger信息的新的 PDCCH format (用于上行调度的 UL grant )。当基站非连续调度 UE 时，基站在向 UE发送的 PDCCH信令中携带 PHR trigger信息。 Step 401: The base station sends, to the UE, PDCCH signaling that carries the PHR trigger information. Specifically, the PHR trigger information may be set to an idle bit in the existing PDCCH format format, or may be set to add PHR trigger information based on the existing DCI format, or define a new one that includes the PHR trigger information. PDCCH format (UL grant for uplink scheduling). When the base station discontinuously schedules the UE, the base station carries the PHR trigger information in the PDCCH signaling sent to the UE.

步骤 402, UE解析接收到的 PDCCH信令，根据 PDCCH信令中携带的 PHR trigger信息向基站发送 PHR报告。 Step 402: The UE parses the received PDCCH signaling, and sends a PHR report to the base station according to the PHR trigger information carried in the PDCCH signaling.

具体的，本发明实施例中，基站与 UE需要约定 PHR trigger信息在 PDCCH信令中的位置， UE根据该约定在特定的位置检测是否存储 PHR trigger信息。另夕卜，基站与 UE之间还需要约定 PHR报告与 PHR trigger触发之间的时间关系符合一定定时关系，这个定时关系可以和 Rd-8中的 UL grant与 PUSCH之间的时间关系保持一致，也可以不一致。 UE根据该时间关系在接收到 PHR trigger信息后向基站发送 PHR 艮告。 Specifically, in the embodiment of the present invention, the base station and the UE need to agree on the location of the PHR trigger information in the PDCCH signaling, and the UE detects whether to store the PHR trigger information at a specific location according to the convention. In addition, the time relationship between the PHR report and the PHR trigger triggering needs to be consistent with a certain timing relationship between the base station and the UE, and the timing relationship may be consistent with the time relationship between the UL grant and the PUSCH in the Rd-8. Can also be inconsistent. The UE sends a PHR advertisement to the base station after receiving the PHR trigger information according to the time relationship.

以 FDD***为例，假定 PHR报告与 PHR trigger触发之间的时间关系为间隔 4个子帧，应用上述功率控制方法后，在 UL grant中增加 lbit PHR trigger信息， UE在下行子帧 k收到包含该 PHR trigger 信息的 UL grant后，在 k+4上行子帧上报 PHR。该 PHR是基于 k+4 上行子帧的信号传输情况计算的。 Taking the FDD system as an example, it is assumed that the time relationship between the PHR report and the PHR trigger is 4 subframes. After the power control method is applied, the lbit PHR trigger information is added to the UL grant, and the UE receives the received packet in the downlink subframe k. After the UL grant of the PHR trigger information, the PHR is reported in the k+4 uplink subframe. The PHR is calculated based on the signal transmission condition of the k+4 uplink subframe.

基站根据 PHR报告对 UE进行调度。本发明实施例三提供一种 PHR上报的方法，如图 5所示，包括以下步骤： The base station schedules the UE according to the PHR report. A third embodiment of the present invention provides a method for reporting a PHR. As shown in FIG. 5, the method includes the following steps:

步骤 501 , 基站向 UE发送携带 PHR trigger信息的 MAC CE信令。 Step 501: The base station sends a MAC CE signaling carrying the PHR trigger information to the UE.

本发明实施例中，需要设置新的调度 MAC CE信令，同时约定 MAC CE调度与 PHR上报之间的定时关系，该定时关系可以为正确接收到触发 MAC CE后的第一个非连续 PRB调度传输，也可以为其他定时关系。当基站非连续调度 UE时，基站在向 UE发送的 MAC CE 信令中携带 PHR trigger信息。 In the embodiment of the present invention, a new scheduling MAC CE signaling needs to be set, and a timing relationship between the MAC CE scheduling and the PHR reporting is agreed, and the timing relationship may be correct. The first non-contiguous PRB scheduling transmission after the MAC CE is triggered may also be other timing relationships. When the base station discontinuously schedules the UE, the base station carries the PHR trigger information in the MAC CE signaling sent to the UE.

步骤 502, UE根据 MAC CE信令中携带的 PHR trigger信息向基站发送 PHR 艮告。 Step 502: The UE sends a PHR advertisement to the base station according to the PHR trigger information carried in the MAC CE signaling.

具体的， UE获取 MAC CE信令中携带的 PHR trigger信息后，根据约定的定时关系向基站发送 PHR报告。 Specifically, after acquiring the PHR trigger information carried in the MAC CE signaling, the UE sends a PHR report to the base station according to the agreed timing relationship.

例如，以定时关系为正确接收到触发 MAC CE后的第一个非连续 PRB调度传输时上报 PHR报告为例， UE在下行子帧 k收到调度触发功率回退报告的 MAC CE信令， UE在上行子帧 k+n进行第一个非连续 PRB传输，因此 UE在上行子帧 k+n上报功率回退的情况。该功率回退的 PHR是基于 k+n上行子帧的信号传输情况计算的。这里的上报还可以设置一个 MAC CE表示功率回退的情况，比如设置为 P-PHR。本发明实施例四提供一种 PHR上报的方法，如图 6所示，包括以下步骤： For example, the UE sends a PHR report to the first non-contiguous PRB scheduling transmission after the MAC CE is triggered. The UE receives the MAC CE signaling of the scheduling trigger power backoff report in the downlink subframe k. The first non-contiguous PRB transmission is performed in the uplink subframe k+n, so the UE reports the power backoff in the uplink subframe k+n. The PHR of the power backoff is calculated based on the signal transmission condition of the k+n uplink subframe. The report here can also set a MAC CE to indicate the power backoff, for example, set to P-PHR. A fourth embodiment of the present invention provides a method for reporting a PHR. As shown in FIG. 6, the method includes the following steps:

步骤 601 , 网络侧对 UE进行非连续 PRB 调度。 Step 601: The network side performs discontinuous PRB scheduling on the UE.

步骤 602, UE在每次非连续 PRB调度时向网络侧发送 PHR报告。 Step 602: The UE sends a PHR report to the network side each time the discontinuous PRB scheduling is performed.

例如，网络侧以 16QAM 的调制等级进行非连续 PRB调度，并且非连续 PRB 间隔是 20个 PRB时， UE上报功率回退情况；网络侧以 QPSK 的调制等级进行非连续 PRB调度，并且非连续 PRB 间隔是 20个 PRB时， UE上报功率回退情况；当网络再次以 16QAM 的调制等级进行非连续 PRB调度，并且非连续 PRB 间隔是 20个 PRB 时， UE仍然上 >¾功率回退情况。本发明实施例五提供一种 PHR上报的方法，如图 7所示，包括以下步骤：步骤 701 , 网络侧对 UE进行非连续 PRB 调度。 For example, when the network side performs the discontinuous PRB scheduling with the modulation level of 16QAM, and the non-contiguous PRB interval is 20 PRBs, the UE reports the power backoff condition; the network side performs the discontinuous PRB scheduling with the modulation level of QPSK, and the discontinuous PRB When the interval is 20 PRBs, the UE reports the power backoff condition; when the network performs the discontinuous PRB scheduling again with the modulation level of 16QAM, and the non-contiguous PRB interval is 20 PRBs, the UE still has a power backoff condition of >3⁄4. A fifth embodiment of the present invention provides a method for reporting a PHR. As shown in FIG. 7, the method includes the following steps: Step 701: The network side performs discontinuous PRB scheduling on the UE.

步骤 702, UE获知当前的非连续 PRB调度，如果已经发送过与当前的非连续 PRB 调度对应的 PHR报告，则不再发送 PHR报告；如果没有发送过与当前的非连续 PRB调度对应的 PHR报告，则向网络侧发送 PHR 艮告。 Step 702: The UE learns the current non-contiguous PRB scheduling. If the PHR report corresponding to the current non-contiguous PRB scheduling has been sent, the PHR report is not sent; if the PHR report corresponding to the current non-contiguous PRB scheduling is not sent. , then send a PHR report to the network side.

例如，网络侧以 16QAM 的调制等级进行非连续 PRB调度，并且非连续 PRB 间隔是 20个 PRB时， UE上报功率回退情况；网络侧以 QPSK 的调制等级进行非连续 PRB调度，并且非连续 PRB 间隔是 20个 PRB时， UE判断没有上报过与该非连续 PRB调度对应的功率回退情况，向网络侧上艮功率回退情况；当网络再次以 16QAM 的调制等级进行非连续 PRB调度，并且非连续 PRB 间隔是 20个 PRB 时，由于 UE判断已经上报过这种非连续 PRB 功率回退情况则此时 UE不再上报功率回退情况。本发明实施例六提供一种 PHR上报的方法，如图 8所示，包括以下步骤： For example, when the network side performs the discontinuous PRB scheduling with the modulation level of 16QAM, and the non-contiguous PRB interval is 20 PRBs, the UE reports the power backoff condition; the network side performs the discontinuous PRB scheduling with the modulation level of QPSK, and the discontinuous PRB When the interval is 20 PRBs, the UE determines that the power backoff corresponding to the discontinuous PRB scheduling is not reported, and the power backoff condition is sent to the network side; when the network performs the discontinuous PRB scheduling again with the modulation level of 16QAM, and When the non-contiguous PRB interval is 20 PRBs, the UE does not report the power backoff condition because the UE has reported that the non-contiguous PRB power backoff has been reported. A sixth embodiment of the present invention provides a method for reporting a PHR. As shown in FIG. 8, the method includes the following steps:

步骤 801 , 网络侧对 UE进行非连续 PRB 调度。 Step 801: The network side performs discontinuous PRB scheduling on the UE.

步骤 802, UE判断功率回退值相差是否小于预设值，如果小于该预设值，则不触发 PHR上报，如果大于该预设值，则执行步骤 803。 Step 802: The UE determines whether the power backoff value is smaller than the preset value. If the preset value is less than the preset value, the PHR report is not triggered. If the preset value is greater than the preset value, step 803 is performed.

步骤 803 , UE向网络侧发送 PHR报告。 Step 803: The UE sends a PHR report to the network side.

例如在多次上行传输的过程中，若终端侧的功率回退值相差小于一定数量级（例如 N dB ), 则不触发 PHR上报，只在功率回退值相差大于 N dB时才进行报告。 For example, in the process of multiple uplink transmissions, if the power backoff values on the terminal side differ by less than a certain order of magnitude (for example, N dB ), the PHR reporting is not triggered, and reporting is only performed when the power backoff values differ by more than N dB.

采用上述实施例四至六的方式时， UE自身触发 PHR报告，设置一个 MAC CE表示功率回退的情况，比如设置为 P-PHR。当网络侧进行非连续 PRB调度时 UE主动触发 MAC CE P-PHR 的上报，使网络侧知道这种情况下 UE的功率回退情况。由于 UE功率回退的情况主要和 UE 的调制方式，和非连续 PRB 间隔有关，存在对功率回退情况进行量化的可能，因此可以每次非连续 PRB 调度都上报 PHR; 也可以对已经上报过的某种功率回退情况，则不再进行上报；或者也可以在功率回退值发生一定变化时再上报。 When the manners of the foregoing embodiments 4 to 6 are adopted, the UE itself triggers the PHR report, and sets a MAC CE to indicate that the power is backed off, for example, is set to P-PHR. When the network side performs the discontinuous PRB scheduling, the UE actively triggers the reporting of the MAC CE P-PHR, so that the network side knows the power backoff of the UE in this case. Since the UE power backoff is mainly related to the modulation mode of the UE and the discontinuous PRB interval, there is a possibility of quantifying the power backoff situation, so the PHR can be reported every time the discontinuous PRB scheduling is performed; It is also possible to report a certain power back-off situation that has been reported, or to report it again when the power back-off value changes.

本发明实施例中，当网络侧对用户终端进行非连续 PRB调度时，用户终端根据配置的 PHR上报策略向网络侧发送 PHR报告，使网络侧获知用户终端的功率回退情况，从而可以使基站对 UE进行合理的调度。 In the embodiment of the present invention, when the network side performs the discontinuous PRB scheduling on the user terminal, the user terminal sends a PHR report to the network side according to the configured PHR reporting policy, so that the network side knows the power backoff of the user terminal, so that the base station can be made. Reasonable scheduling of the UE.

需要说明的是，本发明上述实施例中提供的方法，还可以结合为新的功率控制方法，例如基站向 UE发送携带 PHR trigger信息的 PDCCH信令或者 MAC CE信令后， UE解析 PDCCH信令或者 MAC CE信令获取 PHR trigger信息，但在向网络侧发送 PHR报告之前， UE还需要判断是否大于预设值，在判断结果为是的情况下才向网络侧发送 PHR 艮告。 It should be noted that the method provided in the foregoing embodiment of the present invention may also be combined into a new power control method. For example, after the base station sends the PDCCH signaling or the MAC CE signaling carrying the PHR trigger information to the UE, the UE parses the PDCCH signaling. Or the MAC CE signaling obtains the PHR trigger information, but before sending the PHR report to the network side, the UE needs to determine whether it is greater than the preset value, and sends the PHR advertisement to the network side if the judgment result is yes.

基于如上的 PHR上报方法，基站可以估计得到一个 UE在不同上行传输情况下的功率回退值，具体是通过比较该 UE在不同子帧上报的 PHR得到。例如， UE在上行子帧 X采用连续的 PUSCH资源分配，发射功率为 Ppusch_x , 该子帧上的 PHR 为 PHR_x=Pmax-Ppusch_x； UE在上行子帧 y采用非连续的 PUSCH资源分配，发射功率为 Ppusch_y , 该子帧上报的 PHR 为 PHR_y=Pmax-Pbackoff_y-Ppusch_y„ 这样基站通过 PHR_x与 PHR_y 的差值即可得到类似子帧 y这样的上行传输情况下该终端的功率回退值 Pbackoff_y, 在后续上行资源调度时可以作为参考。这里的每一次 PHR上报可以采用前述的两类方法 (即基站调度触发或者 UE自己触发的情况)。基站通过获得不同传输情况下的 PHR值，可以大致估计各种传输情况下的终端功率回退值，在后续的调度中进行参考。本发明实施例七提供一种网络侧设备，如图 9所示，包括：调度单元 11 , 用于对用户终端进行非连续 PRB调度； Based on the PHR reporting method, the base station can estimate the power backoff value of a UE in different uplink transmission situations, which is obtained by comparing the PHR reported by the UE in different subframes. For example, the UE uses the continuous PUSCH resource allocation in the uplink subframe X, the transmission power is Ppusch_x, and the PHR on the subframe is PHR_x=Pmax-Ppusch_x; the UE uses the discontinuous PUSCH resource allocation in the uplink subframe y, and the transmission power is Ppusch_y , the PHR reported in the subframe is PHR_y=Pmax-Pbackoff_y-Ppusch_y. Thus, the base station can obtain the power backoff value Pbackoff_y of the terminal in the uplink transmission situation like the subframe y by the difference between the PHR_x and the PHR_y. The uplink resource scheduling can be used as a reference. Each of the PHR reports here can adopt the foregoing two types of methods (that is, the base station scheduling trigger or the UE triggers itself). The base station can estimate various PHR values by obtaining different transmission conditions. The terminal power backoff value in the case of the transmission is referred to in the subsequent scheduling. The seventh embodiment of the present invention provides a network side device, as shown in FIG. 9, including: a scheduling unit 11 configured to perform discontinuity on the user terminal. PRB scheduling;

接收单元 12, 用于接收所述用户终端根据配置的 PHR上报策略发送的 PHR ^艮告。还包括： The receiving unit 12 is configured to receive a PHR report sent by the user terminal according to the configured PHR reporting policy. Also includes:

发送单元 13, 用于在向所述用户终端发送的调度信令中携带所述 PHR上报策略。 The sending unit 13 is configured to carry the PHR reporting policy in the scheduling signaling sent to the user terminal.
