一种终端及终端进行信号测量的方法A terminal and a method for performing signal measurement by the terminal

技术领域technical field

本发明涉及通信技术领域，尤其涉及一种终端及终端进行信号测量的方法。The present invention relates to the field of communication technology, in particular to a terminal and a method for performing signal measurement by the terminal.

背景技术Background technique

在无线通信系统中，终端需要选定某个基站作为该终端的服务基站，此时称终端驻留在服务小区，服务小区周围的小区称为邻小区，为支持终端的移动性，终端需要周期或非周期性地监测无线通信网络内的信号，包括服务小区和邻小区的信号质量等。一般来讲，当终端当前所在服务小区的服务质量恶化到一定程度，终端就会启动信号测量，对服务小区和邻小区的信号质量进行监测，其中终端需要测量的频点列表由其当前服务基站下发给终端。如果发现信号质量足够好的小区，则终端会执行重选服务小区或者切换服务小区的命令，将其服务小区转换为所述信号质量足够好的小区。In a wireless communication system, a terminal needs to select a certain base station as the serving base station of the terminal. At this time, the terminal is said to reside in the serving cell, and the cells around the serving cell are called neighboring cells. To support the mobility of the terminal, the terminal needs periodic Or non-periodically monitor the signals in the wireless communication network, including the signal quality of the serving cell and neighboring cells, etc. Generally speaking, when the service quality of the serving cell where the terminal is currently located deteriorates to a certain extent, the terminal will start signal measurement to monitor the signal quality of the serving cell and neighboring cells. The list of frequency points that the terminal needs to measure is determined by its current serving base station sent to the terminal. If a cell with sufficient signal quality is found, the terminal will execute a command to reselect a serving cell or switch a serving cell, and convert its serving cell to the cell with sufficient signal quality.

在传统的无线通信系统中，终端的接收机，任何时刻只在一个单独的频点上工作，因此只能同时对一个频点上的信号进行测量或者接收，在进行信号测量的时候，也只能对频点列表中的频点逐一扫描。但随着通信技术的不断发展，在更先进的无线通信系统中，一个终端能够同时在多个频点上进行通信，具备这种能力的终端，其接收端包含多个接收通道，每个接收通道可以单独工作。假设终端支持两个载波的聚合，终端的接收机结构也发生相应的变化，一个终端可以同时在多个频点上与基站通信，例如，载波聚合场景；同时，由于载波聚合的引入，原来同一物理基站可能会对应多个小区或多个频点，使终端的邻区频点数量增加。In the traditional wireless communication system, the receiver of the terminal only works on a single frequency point at any time, so it can only measure or receive the signal on one frequency point at the same time. Can scan the frequency points in the frequency point list one by one. However, with the continuous development of communication technology, in a more advanced wireless communication system, a terminal can communicate on multiple frequency points at the same time. The receiving end of a terminal with this capability includes multiple receiving channels, each receiving Channels can work individually. Assuming that the terminal supports the aggregation of two carriers, the receiver structure of the terminal also changes accordingly. A terminal can communicate with the base station at multiple frequency points at the same time, for example, in the carrier aggregation scenario; at the same time, due to the introduction of carrier aggregation, the original The physical base station may correspond to multiple cells or multiple frequency points, which increases the number of frequency points in the adjacent cells of the terminal.

本发明人发现现有技术存在如下问题，对于有多个接收通道的终端来说，信号测量时间较长和能耗较大。The inventors found that the prior art has the following problems. For a terminal with multiple receiving channels, the signal measurement time is relatively long and the energy consumption is relatively large.

发明内容Contents of the invention

本发明实施例提供的终端进行信号测量的方法及终端，多个接收通道同时在不同频点接收参考信号并对接收到的参考信号进行测量，多个通道并行测量，对于确定的频点数量，相对于单个通道逐个测量或多个通道交替测量，减少了测量过程所需时间；因为终端的功率消耗并不与其处理能力成线性正比，多个通道同时进行测量，其能量消耗是小于通道数量倍数，故多个通道并行进行测量，相对于单个通道逐个测量，减少了终端的能耗。In the method and terminal for signal measurement by a terminal provided in the embodiments of the present invention, multiple receiving channels simultaneously receive reference signals at different frequency points and measure the received reference signals, and multiple channels measure in parallel. For the determined number of frequency points, Compared with the measurement of a single channel one by one or multiple channels alternately, the time required for the measurement process is reduced; because the power consumption of the terminal is not linearly proportional to its processing capability, multiple channels are measured at the same time, and its energy consumption is less than a multiple of the number of channels , so multiple channels are measured in parallel, which reduces the energy consumption of the terminal compared with the measurement of a single channel one by one.

具体实施方式Detailed ways

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

实施例一Embodiment one

如图4所示，本发明实施例终端进行信号测量的方法，包括如下步骤：As shown in FIG. 4, the method for performing signal measurement by a terminal in an embodiment of the present invention includes the following steps:

S1、通过至少两个接收通道同时在不同频点接收参考信号；S1. Simultaneously receive reference signals at different frequency points through at least two receiving channels;

S2、同时对所述至少两个接收通道接收到的所述参考信号进行测量。S2. Simultaneously measure the reference signals received by the at least two receiving channels.

发明人发现，对于有多个接收通道的终端，现有技术中终端进行信号测量时，如图1所示，对频点进行逐一信号测量的方法，一方面会造成终端测量时间加长，同时，另一方面也没有充分利用终端的硬件能力，导致终端能耗增加。The inventors have found that, for a terminal with multiple receiving channels, when the terminal performs signal measurement in the prior art, as shown in Figure 1, the method of performing signal measurement on frequency points one by one will, on the one hand, lengthen the measurement time of the terminal, and at the same time, On the other hand, the hardware capabilities of the terminal are not fully utilized, resulting in increased energy consumption of the terminal.

本发明实施例基于终端具有至少两个接收通道，每个接收通道可以单独工作。例如，如图2所示，终端的接收机包括两个独立的射频(RF，Radio Frequency)芯片，即每个接收通道包括一个射频芯片，每个射频芯片对应一个载波的接收；或者如图3所示，终端接收机的一个射频芯片集成了两个接收通道的射频接收模块，每个接收通道对应一个载波的接收。在上述两种结构接收机的终端中，I/O为接收通道的射频处理模块与基带(BB，Base Band)处理模块的输入输出接口；基带处理模块之后连接有应用模块。如图5所示，多个接收通道同时在不同频点接收参考信号并对接收到的参考信号进行测量，多个通道并行测量，对于确定的频点数量，相对于单个通道逐个测量或多个通道交替测量，减少了测量过程所需时间；因为终端的功率消耗并不与其处理能力成线性正比，多个通道同时进行测量，其能量消耗是小于通道数量倍数，故多个通道并行进行测量，相对于单个通道逐个测量，减少了终端的能耗。The embodiment of the present invention is based on the fact that the terminal has at least two receiving channels, and each receiving channel can work independently. For example, as shown in Figure 2, the receiver of the terminal includes two independent radio frequency (RF, Radio Frequency) chips, that is, each receiving channel includes a radio frequency chip, and each radio frequency chip corresponds to the reception of a carrier; or as shown in Figure 3 As shown, a radio frequency chip of the terminal receiver integrates radio frequency receiving modules of two receiving channels, and each receiving channel corresponds to the reception of a carrier. In the terminals of the receivers with the above two structures, the I/O is the input and output interface between the radio frequency processing module of the receiving channel and the baseband (BB, Base Band) processing module; the baseband processing module is connected with an application module. As shown in Figure 5, multiple receiving channels receive reference signals at different frequency points at the same time and measure the received reference signals. Multiple channels measure in parallel. For a certain number of frequency points, relative to a single channel, one by one or multiple Channels are measured alternately, which reduces the time required for the measurement process; because the power consumption of the terminal is not linearly proportional to its processing capacity, multiple channels are measured at the same time, and its energy consumption is less than the multiple of the number of channels, so multiple channels are measured in parallel. Compared with measuring a single channel one by one, the energy consumption of the terminal is reduced.

为了使本领域的技术人员更好地理解上述方法的技术方案，下面对本发明实施例作进一步的详细说明。In order to enable those skilled in the art to better understand the technical solution of the above method, the embodiments of the present invention will be further described in detail below.

实施例二Embodiment two

如图6所示，本发明实施例基于实施一，包括如下步骤：As shown in Figure 6, the embodiment of the present invention is based on implementation one, including the following steps:

S21、终端启动信号测量。S21. The terminal starts signal measurement.

当终端所在服务小区的服务质量恶化到一定程度时，终端启动信号测量，对邻小区和本小区的信号质量进行监测，终端所在服务小区的基站向小区内的终端下发频点列表，所述频点列表来源于终端邻小区的工作频点。When the service quality of the serving cell where the terminal is located deteriorates to a certain extent, the terminal starts signal measurement to monitor the signal quality of neighboring cells and this cell, and the base station of the serving cell where the terminal is located sends a list of frequency points to the terminals in the cell. The frequency point list is derived from the working frequency points of the neighboring cells of the terminal.

S22、接收由基站下发的频点列表。S22. Receive the frequency point list issued by the base station.

根据不同的通信系统，此时基站向终端发送的数据可能不仅包括频点列表，还可能包括一些身份信息，终端根据这些频点对信号进行测量。According to different communication systems, the data sent by the base station to the terminal at this time may not only include a list of frequency points, but may also include some identity information, and the terminal measures signals according to these frequency points.

S23、判断终端是否具有至少两个接收通道。S23. Determine whether the terminal has at least two receiving channels.

若终端具有单通道，则终端按照现有技术，依次将终端调谐至频点列表上的频点对信号进行测量。If the terminal has a single channel, according to the prior art, the terminal tunes the terminal to the frequency points on the frequency point list in order to measure the signal.

若终端具有至少两个接收通道，那么进入步骤S24。If the terminal has at least two receiving channels, go to step S24.

S24、终端向所述至少两个接收通道下发开启命令，所述至少两个接收通道根据所述开启命令，等待接收所述参考信号。S24. The terminal sends an enabling command to the at least two receiving channels, and the at least two receiving channels wait to receive the reference signal according to the enabling command.

激活终端的所有接收通道，以等待接收参考信号。若终端的所有接收通道都已激活，则可跳过此步骤。终端处于移动过程中的空闲状态或连接状态，均可由终端自主开启接收通道，使每个接收通道均处于激活状态。Activate all receive channels of the terminal to wait for the reception of the reference signal. If all receiving channels of the terminal are activated, this step can be skipped. When the terminal is in the idle state or connected state during the movement process, the receiving channel can be opened by the terminal independently, so that each receiving channel is in an active state.

实施例一中步骤S2、通过至少两个接收通道同时在不同频点接收参考信号，具体包括如下步骤：Step S2 in the first embodiment, receiving reference signals at different frequency points simultaneously through at least two receiving channels, specifically includes the following steps:

S25、所述至少两个接收通道调谐至所述频点列表中的不同频点。S25. The at least two receiving channels are tuned to different frequency points in the frequency point list.

依照频点列表中的频点，每个接收通道调整内部电路参数，使接收通道工作于频点列表中的一个频点。其中，同一时刻，每个接收通道调谐至的频点不同。According to the frequency points in the frequency point list, each receiving channel adjusts the internal circuit parameters to make the receiving channel work at a frequency point in the frequency point list. Wherein, at the same moment, each receiving channel is tuned to a different frequency point.

S26、所述至少两个接收通道在各所述频点上同时接收所述参考信号。S26. The at least two receiving channels simultaneously receive the reference signal at each of the frequency points.

每个接收通道在各自调谐至的频点上搜索同步信息以保持与基站的同步状态，接收通道接收到同步信息，对同步信息进行小区识别，之后接收来自该小区的参考信号，例如，在如LTE系统中，接收通道接收CRS(Cell-specific Reference Signal，蜂窝网专用参考信号)。Each receiving channel searches for synchronization information on the frequency point to which it is tuned to to maintain the synchronization state with the base station. After receiving the synchronization information, the receiving channel performs cell identification on the synchronization information, and then receives a reference signal from the cell, for example, in such as In the LTE system, the receiving channel receives CRS (Cell-specific Reference Signal, cellular network dedicated reference signal).

S27、同时对所述至少两个接收通道接收到的所述参考信号进行测量。具体为：通过评估所述参考信号的接收功率，进而评价信号质量。S27. Simultaneously measure the reference signals received by the at least two receiving channels. Specifically, the signal quality is further evaluated by evaluating the received power of the reference signal.

更为具体地，每个接收通道对接收到的参考信号进行下变频，将参考信号去掉其中的射频成分后得到一个模拟信号，对该模拟信号进行模数转换；或者先对参考信号进行采样后，再进行下变频处理；在上述步骤结束后，计算此时参考信号的功率平均值，若在LTE系统中，CRS强度可以用RSRP(Reference Signal Receiving Power，参考信号接收功率)来衡量。需要说明的是，在实际应用中，计算平均功率之前，还有提取参考信号的步骤，因为接收通道在接收参考信号时，还可能伴随着接收其他数据。More specifically, each receiving channel down-converts the received reference signal, removes the radio frequency component of the reference signal to obtain an analog signal, and performs analog-to-digital conversion on the analog signal; or first samples the reference signal and then , and then perform down-conversion processing; after the above steps are completed, calculate the average power of the reference signal at this time. If in the LTE system, the CRS strength can be measured by RSRP (Reference Signal Receiving Power, reference signal receiving power). It should be noted that, in practical applications, before calculating the average power, there is still a step of extracting the reference signal, because when the receiving channel receives the reference signal, it may also receive other data along with it.

至少两个接收通道共同完成了频点列表中所有频点的测量后，对在所有频点上获取的参考信号接收功率平均值进行排序，从中选取较好的小区，进行小区重选或小区切换的操作。其中参考信号接收功率平均值较大，说明该小区的信号质量较好。After at least two receiving channels have jointly completed the measurement of all frequency points in the frequency point list, sort the average value of the reference signal received power obtained on all frequency points, select a better cell from it, and perform cell reselection or cell switching operation. Wherein, the average value of the received power of the reference signal is relatively large, indicating that the signal quality of the cell is relatively good.

本发明实施例，在上述步骤之后，还包括如下步骤：The embodiment of the present invention, after the above steps, further includes the following steps:

S28、根据测量结果，保留所述至少两个接收通道中的一个接收通道开启，关闭其他接收通道。S28. According to the measurement result, keep one of the at least two receiving channels turned on, and turn off the other receiving channels.

保留一个接收通道工作，是为了在终端重选小区或小区切换后降低终端的能耗。Reserving one receiving channel is to reduce the energy consumption of the terminal after the terminal reselects a cell or switches over a cell.

本发明实施例由终端自主打开接收通道进行信号测量，适用于终端在移动过程中空闲状态及连接状态下的信号测量，多个接收通道同时测量，减少了测量时间，因为终端的功率消耗并不与其处理能力成线性正比，多个通道同时进行测量，其能量消耗小于通道数量倍数，多个通道并行进行测量，减少了终端的能耗。In the embodiment of the present invention, the terminal independently opens the receiving channel for signal measurement, which is suitable for the signal measurement of the terminal in the idle state and connected state during the mobile process. Multiple receiving channels are measured at the same time, which reduces the measurement time, because the power consumption of the terminal is not high. It is linearly proportional to its processing capacity, multiple channels are measured at the same time, and its energy consumption is less than the multiple of the number of channels, and multiple channels are measured in parallel, reducing the energy consumption of the terminal.

实施例三Embodiment three

本发明实施例基于实施例一，与实施例二基本相同，包括如下步骤：The embodiment of the present invention is based on the first embodiment, which is basically the same as the second embodiment, including the following steps:

S31、终端启动信号测量。S31. The terminal starts signal measurement.

S32、接收由基站下发的频点列表。S32. Receive the frequency point list issued by the base station.

S33、判断终端是否具有至少两个接收通道。S33. Determine whether the terminal has at least two receiving channels.

若终端具有单通道，则终端按照现有技术，依次将终端调谐至频点列表上的频点对信号进行测量。If the terminal has a single channel, according to the prior art, the terminal tunes the terminal to the frequency points on the frequency point list in order to measure the signal.

若终端具有至少两个接收通道，基站根据所述基站保存的终端接收通道开启/关闭信息，判断是否所有接收通道均开启，如果已经都开启，进入步骤S35，否则基站下发开启所述至少两个接收通道的命令，终端执行步骤S34，步骤S34与实施例二步骤S24不同。If the terminal has at least two receiving channels, the base station judges whether all the receiving channels are open according to the opening/closing information of the terminal receiving channels saved by the base station. To receive a channel command, the terminal executes step S34, which is different from step S24 in the second embodiment.

S34、接收由基站下发的开启所述至少两个接收通道的命令，所述至少两个接收通道根据所述基站下发的命令，等待接收所述参考信号。S34. Receive a command issued by the base station to enable the at least two receiving channels, and the at least two receiving channels wait to receive the reference signal according to the command issued by the base station.

由基站下发开启终端各接收通道的命令，适用于终端处于移动过程中的链接状态。The command issued by the base station to open each receiving channel of the terminal is applicable to the connection state when the terminal is in the process of moving.

S35、所述至少两个接收通道调谐至所述频点列表中的不同频点，在各所述频点上同时接收所述参考信号。S35. The at least two receiving channels tune to different frequency points in the frequency point list, and simultaneously receive the reference signal at each of the frequency points.

S36、同时对所述至少两个接收通道接收到的所述参考信号进行测量。S36. Simultaneously measure the reference signals received by the at least two receiving channels.

S37、根据测量结果，保留所述至少两个接收通道中的一个接收通道开启，关闭其他接收通道。S37. According to the measurement result, keep one of the at least two receiving channels turned on, and turn off the other receiving channels.

本发明实施例示出了终端进行信号测量的另一种实施例，终端接收由基站对终端的接收通道下发的开启命令，本发明实施例适用于终端处于移动过程中的链接状态，多个接收通道同时进行信号测量，减少了测量时间，因为终端的功率消耗并不与其处理能力成线性正比，多个通道同时进行测量，其能量消耗小于通道数量倍数，多个通道并行进行测量，减少了终端的能耗。The embodiment of the present invention shows another embodiment in which the terminal performs signal measurement. The terminal receives the open command issued by the base station to the receiving channel of the terminal. Channels measure signals at the same time, which reduces the measurement time, because the power consumption of the terminal is not linearly proportional to its processing capability. If multiple channels are measured at the same time, the energy consumption is less than the multiple of the number of channels. Multiple channels are measured in parallel, reducing the terminal energy consumption.

实施例四Embodiment four

如图8所示，本发明实施例还提供了一种终端，能够减少终端进行信号测量的能耗和时间。As shown in FIG. 8 , an embodiment of the present invention also provides a terminal, which can reduce energy consumption and time for signal measurement by the terminal.

所述终端1包括：至少两个接收通道2，用于同时在不同频点接收参考信号；处理模块3，用于同时对所述至少两个接收通道接收到的所述参考信号进行测量。The terminal 1 includes: at least two receivingchannels 2, configured to simultaneously receive reference signals at different frequency points; aprocessing module 3, configured to simultaneously measure the reference signals received by the at least two receiving channels.

多个接收通道同时在不同频点接收参考信号并对接收到的参考信号进行测量，多个通道并行测量，对于确定的频点数量，相对于单个通道逐个测量或多个通道交替测量，减少了测量过程所需时间；因为终端的功率消耗并不与其处理能力成线性正比，多个通道同时进行测量，其能量消耗是小于通道数量倍数，故多个通道并行进行测量，相对于单个通道逐个测量，减少了终端的能耗。Multiple receiving channels receive reference signals at different frequency points at the same time and measure the received reference signals. Multiple channels measure in parallel. For a certain number of frequency points, compared with single channel measurement one by one or multiple channels alternate measurement, it reduces The time required for the measurement process; because the power consumption of the terminal is not linearly proportional to its processing capability, multiple channels are measured at the same time, and the energy consumption is less than the multiple of the number of channels, so multiple channels are measured in parallel, compared to a single channel. , reducing the energy consumption of the terminal.

进一步地，本发明实施例终端包括命令下发模块，用于根据处理模块的测量结果，保留所述至少两个接收通道中的一个接收通道开启，关闭其他接收通道。Further, the terminal in the embodiment of the present invention includes a command issuing module, configured to keep one of the at least two receiving channels open and close the other receiving channels according to the measurement result of the processing module.

保留一个接收通道工作，是为了在终端重选小区或小区切换后降低终端的能耗。Reserving one receiving channel is to reduce the energy consumption of the terminal after the terminal reselects a cell or switches over a cell.

进一步地，本发明实施例所述命令下发模块，还用于向所述至少两个接收通道下发开启命令，使所述至少两个接收通道等待接收所述参考信号。Further, the command issuing module in the embodiment of the present invention is further configured to issue an enabling command to the at least two receiving channels, so that the at least two receiving channels wait to receive the reference signal.

若终端处于移动过程中的空闲状态或连接状态，均可由终端自主开启接收通道，使每个接收通道均处于激活状态。If the terminal is in the idle state or connected state during the moving process, the terminal can independently open the receiving channel, so that each receiving channel is in an active state.

进一步地，本发明实施例所述至少两个接收通道，还用于接收由基站下发的开启所述至少两个接收通道的命令，根据所述基站下发的命令，等待接收所述参考信号。Further, the at least two receiving channels in the embodiment of the present invention are also used to receive a command issued by the base station to open the at least two receiving channels, and wait to receive the reference signal according to the command issued by the base station .

若终端处于移动过程中的链接状态，则打开终端接收通道的命令也可以由基站来下发，终端接收该命令并开启所述至少两个接收通道。If the terminal is in the link state during the moving process, the command to open the receiving channel of the terminal may also be issued by the base station, and the terminal receives the command and opens the at least two receiving channels.

进一步地，本发明实施例所述至少两个接收通道，还用于接收由基站下发的频点列表，根据所述频点列表，调谐至所述频点列表中的不同频点。Further, the at least two receiving channels in the embodiment of the present invention are also used to receive a frequency point list issued by the base station, and tune to different frequency points in the frequency point list according to the frequency point list.

当终端所在服务小区的服务质量恶化到一定程度时，终端启动信号测量，对邻小区和本小区的信号质量进行监测，终端所在服务小区的基站向小区内的终端下发频点列表，所述频点列表来源于终端邻小区的工作频点。在不同的通信系统中，此时基站向终端发送的数据可能不仅包括频点列表，还可能包括一些身份信息。依照频点列表中的频点，每个接收通道调整内部电路参数，使接收通道工作于频点列表中的一个频点。其中，同一时刻，每个接收通道调谐至的频点不同。When the service quality of the serving cell where the terminal is located deteriorates to a certain extent, the terminal starts signal measurement to monitor the signal quality of neighboring cells and this cell, and the base station of the serving cell where the terminal is located sends a list of frequency points to the terminals in the cell. The frequency point list is derived from the working frequency points of the neighboring cells of the terminal. In different communication systems, the data sent by the base station to the terminal at this time may not only include a frequency point list, but may also include some identity information. According to the frequency points in the frequency point list, each receiving channel adjusts the internal circuit parameters to make the receiving channel work at a frequency point in the frequency point list. Wherein, at the same moment, each receiving channel is tuned to a different frequency point.

每个接收通道在各自调谐至的频点上搜索同步信息以保持与基站的同步状态，接收通道接收同步信息，对同步信息进行小区识别，之后接收来自该小区的参考信号，例如，在如LTE系统中，接收通道接收CRS(Cell-specific Reference Signal，蜂窝网专用参考信号)。每个接收通道对接收到的参考信号进行下变频，将参考信号去掉其中的射频成分后得到一个模拟信号，对该模拟信号进行模数转换；或者先对参考信号进行采样后，再进行下变频处理；在上述步骤结束后，计算此时参考信号的功率平均值，若在LTE系统中，CRS强度可以用RSRP(ReferenceSignal Receiving Power，参考信号接收功率)来衡量。需要说明的是，在实际应用中，计算平均功率之前，还有提取参考信号的步骤，因为接收通道在接收参考信号时，还可能伴随着接收其他数据。Each receiving channel searches for synchronization information on the frequency point to which it is tuned to maintain synchronization with the base station. The receiving channel receives the synchronization information, performs cell identification on the synchronization information, and then receives a reference signal from the cell, for example, in LTE In the system, the receiving channel receives CRS (Cell-specific Reference Signal, cellular network dedicated reference signal). Each receiving channel down-converts the received reference signal, removes the RF component of the reference signal to obtain an analog signal, and performs analog-to-digital conversion on the analog signal; or first samples the reference signal, and then performs down-conversion Processing; after the above steps are completed, calculate the power average value of the reference signal at this time, if in the LTE system, the CRS strength can be measured by RSRP (ReferenceSignal Receiving Power, reference signal received power). It should be noted that, in practical applications, before calculating the average power, there is still a step of extracting the reference signal, because when the receiving channel receives the reference signal, it may also receive other data along with it.

下面以终端具有两个接收通道作为举例说明，对本发明实施例的有益效果相对于现有技术做具体说明。Taking the terminal having two receiving channels as an example below, the beneficial effects of the embodiments of the present invention will be described in detail relative to the prior art.

针对如图2所示的接收机结构，每个接收通道包括一个独立的射频芯片。For the receiver structure shown in Figure 2, each receiving channel includes an independent radio frequency chip.

对于图2所示的接收机结构来说，若

则双通道测量消耗的能量更少。而这是一个比较明显的结论，因为一个芯片的功率消耗并不是与其处理的带宽成线性正比的，带宽为两倍，其功率消耗是小于两倍的。因此，对于该结构的接收机来说，多通道并行测量更为省电。For the receiver structure shown in Figure 2, if

Then the two-channel measurement consumes less energy. And this is a relatively obvious conclusion, because the power consumption of a chip is not linearly proportional to its processing bandwidth, the bandwidth is twice, and its power consumption is less than twice. Therefore, for the receiver of this structure, multi-channel parallel measurement saves more power.

针对如图3所示的接收机结构，两个接收通道集成于一个射频芯片。For the receiver structure shown in Figure 3, two receiving channels are integrated into one radio frequency chip.

假设，单通道测量N个频点所需要的总时间为T；每个射频芯片(包括I/O)的功率在进行单通道测量时为P_{1_RF}，在进行双通道测量时为P_{2_RF}；基带处理单元在单通道进行测量时的功耗为P_{1_BB}，在进行双通道测量时的功耗为P_{2_NN}。Assume that the total time required for single-channel measurement of N frequency points is T; the power of each radio frequency chip (including I/O) is P_{1_RF} when performing single-channel measurement, and P_{2_RF} when performing dual-channel measurement; the baseband The power consumption of the processing unit when performing single-channel measurement is P_{1_BB} , and the power consumption when performing dual-channel measurement is P_{2_NN} .

E_{1_RF_ALL}＝P_{1_RF}×T；E_{1_RF_ALL} = P_{1_RF} ×T;

基带处理单元消耗的能量为：The energy consumed by the baseband processing unit is:

E_{1_BB_ALL}＝P_{1_BB}×T；E_{1_BB_ALL} = P_{1_BB} ×T;

测量N个频点消耗的总能量为：The total energy consumed by measuring N frequency points is:

E_{1_ALL}＝E_{1_RF_ALL}+E_{1_BB_ALL}。E_{1_ALL} =E_{1_RF_ALL} +E_{1_BB_ALL} .

对于采用图3所示结构的接收机来说，有

因此双通道测量消耗的能量更少，而且省电效果比对于图2结构的接收机更为明显。For the receiver using the structure shown in Figure 3, there are

Therefore, the two-channel measurement consumes less energy, and the power saving effect is more obvious than that of the receiver with the structure shown in Fig. 2 .

综上所述，测量相同数目的频道时，对于两种接收机结构，多通道并行测量从时间和能量上都是节省的。需要说明的是，本方法还可以用于其它多接收机/多接收通道的场景，对频点进行并行测量。To sum up, when measuring the same number of channels, for both receiver structures, multi-channel parallel measurement saves both time and energy.
