背景技术Background technique
双模异系统相互测量是指，在当前驻留的模式中捕获另一种模式的网络状态：对来自第二无线接入技术(RAT)基站的下行链路进行测量，对第二无线接入技术基站的网络进行捕获。在时分同步码分多址(TD-SCDMA，Time Division-Synchronous Code DivisionMultiple Access)与分时长期演进(TD-LTE，Time Division Long Term Evolution)双模系统的相互测量技术中，可以在TD-SCDMA模式中对TD-LTE模式进行测量，也可以在TD-LTE模式中对TD-SCDMA模式进行测量。Dual-mode different system mutual measurement refers to capturing the network status of another mode in the current camping mode: measuring the downlink from the second radio access technology (RAT) base station, and measuring the downlink from the second radio access technology (RAT) base station. Network of technology base stations for capture. In the mutual measurement technology of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) and Time Division Long Term Evolution (TD-LTE, Time Division Long Term Evolution) dual-mode system, it can be used in TD-SCDMA TD-LTE mode can be measured in TD-LTE mode, and TD-SCDMA mode can also be measured in TD-LTE mode.
这些测量技术中都需要假设双模的帧边界是对齐的，TD-SCDMA模式与TD-LTE模式在移动终端(UE)有相同的帧边界，UE按照当前驻留(连接)的通信模式(第一通信模式)的时隙转换点调谐到第二无线接入技术基站的频点，接收第二无线接入技术基站的信号，从而测量异系统(第二通信模式)。These measurement techniques all need to assume that the frame boundaries of the dual-mode are aligned. The TD-SCDMA mode and the TD-LTE mode have the same frame boundaries in the mobile terminal (UE), and the UE follows the current resident (connected) communication mode (section The time slot conversion point of the first communication mode) is tuned to the frequency point of the second radio access technology base station, and the signal of the second radio access technology base station is received, thereby measuring the different system (second communication mode).
现有技术存在如下问题：在TD-SCDMA与TD-LTE双模式中，由于TD-SCDMA与TD-LTE具有不同的帧结构，TD-SCDMA与TD-LTE很容易出现时隙不对齐的情况，很容易造成交叉时隙带来的干扰，若进行时隙对齐，两种模式的帧结构需要专门的配置，才能实现时隙对齐。The existing technology has the following problems: in the dual mode of TD-SCDMA and TD-LTE, since TD-SCDMA and TD-LTE have different frame structures, TD-SCDMA and TD-LTE are prone to misalignment of time slots, It is easy to cause interference caused by cross-slots. If time slots are aligned, the frame structures of the two modes need special configuration to achieve time slot alignment.

具体实施方式Detailed ways
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
3GPP定义了长期演进(LTE，Long Term Evolution)模式的FDD和TDD技术的帧结构，帧长度都为10ms。The 3GPP defines the frame structure of the FDD and TDD technologies of the Long Term Evolution (LTE, Long Term Evolution) mode, and the frame length is 10 ms.
如图2所示，TD-LTE模式的帧结构，10ms帧分成两个半帧，共含有10个子帧(Subframe)，每个子帧长度1ms。第2子帧和第7子帧为特殊子帧，一个特殊子帧包括3部分：下行同步时隙(DwPTS)，保护时隙(GP，Guard Point)和上行时隙(UpPTS)。As shown in FIG. 2 , in the frame structure of the TD-LTE mode, a 10ms frame is divided into two half frames, including 10 subframes in total, and each subframe has a length of 1ms. The second subframe and the seventh subframe are special subframes, and a special subframe includes three parts: downlink synchronization time slot (DwPTS), guard time slot (GP, Guard Point) and uplink time slot (UpPTS).
假设带宽为20MHz，一个正交频分复用技术(OFDM，Orthogonal FrequencyDivision Multiplexing)符号(symbol)对应的时间为0.071354ms。Assuming that the bandwidth is 20 MHz, the time corresponding to one Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) symbol (symbol) is 0.071354 ms.
TD-LTE模式中，TDD上下行带宽不是固定的，有两个时隙转换点，时隙转换点是一个时间意义上的位置：In TD-LTE mode, TDD uplink and downlink bandwidth is not fixed, there are two time slot switching points, and the time slot switching point is a position in the sense of time:
常规时隙中，常规时隙转换点是指上行时隙与下行时隙的时隙转换点(UDSP，uplink-to-downlink switching point)，UDSP位于上行子帧与下行子帧转换的帧边界位置。In the regular time slot, the regular time slot switching point refers to the time slot switching point (UDSP, uplink-to-downlink switching point) between the uplink time slot and the downlink time slot, and the UDSP is located at the frame boundary position between the uplink subframe and the downlink subframe .
特殊时隙中，下行同步时隙(DwPTS)与上行同步时隙(UpPTS)之间能够进行转换，DwPTS与UpPTS之间的保护间隔GP即为特殊时隙转换点(DUSP，downlink-to-uplinkswitching point)，对应着小区半径r=(TGP/2)*c，其中，TGP是保护间隔GP对应的时间，c为光速。In the special time slot, the downlink synchronous time slot (DwPTS) and the uplink synchronous time slot (UpPTS) can be switched, and the guard interval GP between DwPTS and UpPTS is the special time slot switching point (DUSP, downlink-to-uplink switching point), corresponding to the cell radius r=(TGP/2)*c, where TGP is the time corresponding to the guard interval GP, and c is the speed of light.
如图3所示，TD-SCDMA模式的帧结构，10ms帧分为两个5ms子帧，每个5ms子帧包括7个常规时隙和1个特殊时隙。每个常规时隙包括两个数据(Data)部分和一个中间码(Midamble)部分，以及16个时间片(chip)的GP作为最后部分，数据部分为352chip(带宽1.28MHz)，中间码部分为128chip；特殊时隙是352chip，包括三部分：DwPTS(96chip)，GP(96chip)和UpPTS(160chip)。As shown in Figure 3, the frame structure of TD-SCDMA mode, a 10ms frame is divided into two 5ms subframes, each 5ms subframe includes 7 regular time slots and 1 special time slot. Each regular time slot includes two data (Data) parts and a midamble (Midamble) part, and GP of 16 time slices (chip) as the last part, the data part is 352chip (bandwidth 1.28MHz), and the midamble part is 128chip; the special time slot is 352chip, including three parts: DwPTS (96chip), GP (96chip) and UpPTS (160chip).
TD-SCDMA模式中，常规时隙中，常规时隙转换点(上行时隙与下行时隙的时隙转换点，UDSP)是指每一个时隙末尾的GP(16chip)，该GP作为时隙对齐的保护时隙。In TD-SCDMA mode, in the regular time slot, the regular time slot switching point (the time slot switching point between the uplink time slot and the downlink time slot, UDSP) refers to the GP (16chip) at the end of each time slot, and the GP is used as the time slot Aligned guard slots.
TD-LTE与TD-SCDMA共存时对时隙进行对齐配置应当遵循：When TD-LTE and TD-SCDMA coexist, the time slot alignment configuration should follow:
首先，如图4所示，保证两个模式的常规时隙转换点UDSP对齐。First, as shown in Fig. 4, it is ensured that the conventional time slot switching points UDSP of the two modes are aligned.
其次，如图5所示，调整TD-LTE模式中特殊子帧的GP长度，给出特殊时隙中DwPTS，GP和UpPTS的配比关系，一般情况下，TD-LTE模式的特殊子帧的GP比TD-SCDMA模式的特殊时隙的GP要大，在设置帧结构配比过程中，保证TD-SCDMA特殊时隙的GP(0.075ms)落在TD-LTE的特殊子帧的GP中，这是因为TD-LTE的特殊子帧的GP长度可变，最小为一个OFDM符号对应的时间，比如：带宽为20MHz时，最小的GP长度为0.071354ms。Secondly, as shown in Figure 5, the GP length of the special subframe in the TD-LTE mode is adjusted, and the ratio relationship between DwPTS, GP and UpPTS in the special time slot is given. In general, the special subframe of the TD-LTE mode The GP is larger than the GP of the special time slot in TD-SCDMA mode. In the process of setting the frame structure ratio, ensure that the GP of the TD-SCDMA special time slot (0.075ms) falls in the GP of the special subframe of TD-LTE. This is because the GP length of the TD-LTE special subframe is variable, and the minimum is the time corresponding to one OFDM symbol. For example, when the bandwidth is 20MHz, the minimum GP length is 0.071354ms.
这一过程中，在保证常规时隙转换点UDSP对齐的前提下，按照TD-SCDMA的不同的时隙配比，可以确定出TD-LTE模式的特殊子帧的位置以及其GP的长度，保证了TD-SCDMA特殊时隙的GP落在TD-LTE特殊时隙对应的GP之内，如此则可以认为特殊时隙实现了对齐。In this process, under the premise of ensuring the UDSP alignment of the conventional time slot conversion point, according to the different time slot ratios of TD-SCDMA, the position of the special subframe of the TD-LTE mode and the length of its GP can be determined to ensure If the GP of the TD-SCDMA special time slot falls within the GP corresponding to the TD-LTE special time slot, it can be considered that the special time slot is aligned.
本发明实施例提供一种双通信模式中互相检测对方模式参数的方法，应用于移动终端，如图1所示，包括：An embodiment of the present invention provides a method for detecting each other's mode parameters in a dual communication mode, which is applied to a mobile terminal, as shown in FIG. 1 , including:
步骤101，移动终端处于第一通信模式，执行第一通信模式与第二通信模式进行时隙对齐的操作；Step 101, the mobile terminal is in the first communication mode, and performs the operation of time slot alignment between the first communication mode and the second communication mode;
步骤102，根据第一通信模式的帧结构和时隙配比，以及第二通信模式的帧结构和时隙配比；从所述第一通信模式的常规时隙转换点推算出在第二通信模式中应当检测的参数所在的检测位置；Step 102, according to the frame structure and time slot ratio of the first communication mode, and the frame structure and time slot ratio of the second communication mode; The detection position of the parameter that should be detected in the pattern;
步骤103，在第二通信模式的所述检测位置处开始检测所述参数。Step 103, starting to detect the parameter at the detection position in the second communication mode.
应用所提供的技术，双模式共存的情形下，通过采用时隙对齐降低异系统之间的交叉时隙带来的干扰，在双模式的时隙对齐后，找到恰当的检测位置启动对另一种模式的测量，实现了不需要专门的配置就能够检测到另一种模式下的各种参数。Apply the provided technology, in the case of dual-mode coexistence, reduce the interference caused by cross-slots between different systems by using time slot alignment, and find the appropriate detection position to start the other system after the dual-mode time slots are aligned The measurement of one mode realizes the detection of various parameters in another mode without special configuration.
在一个优选实施例中，第一通信模式是TD-SCDMA模式，第二通信模式是TD-LTE模式。In a preferred embodiment, the first communication mode is TD-SCDMA mode, and the second communication mode is TD-LTE mode.
或者，第一通信模式是TD-LTE模式，第二通信模式是TD-SCDMA模式。Or, the first communication mode is TD-LTE mode, and the second communication mode is TD-SCDMA mode.
双模式支持实现时隙对齐，如图5所示，其支持各种配比条件下的时隙对齐。以TD-SCDMA时隙配比2:5为例，除了下行TS0时隙外，配置4个下行时隙，2个上行时隙，TD-LTE采用时隙配比1:3。不同模式的基站保持时隙对齐的收发时钟定时机制以保持同步，以及，移动终端知道两种模式的时隙配比，移动终端在不同模式下接收的信号满足时隙对齐。The dual mode supports time slot alignment, as shown in Figure 5, which supports time slot alignment under various configuration conditions. Taking TD-SCDMA with a time slot ratio of 2:5 as an example, in addition to the downlink TS0 time slot, 4 downlink time slots and 2 uplink time slots are configured, and TD-LTE adopts a time slot ratio of 1:3. The base stations in different modes maintain the time slot aligned transceiver clock timing mechanism to maintain synchronization, and the mobile terminal knows the time slot ratio of the two modes, and the signals received by the mobile terminal in different modes meet the time slot alignment.
在一个优选实施例中，从所述第一通信模式的常规时隙转换点推算出应当检测的参数所在的检测位置，包括：In a preferred embodiment, the detection position of the parameter to be detected is deduced from the normal time slot switching point of the first communication mode, including:
确定TD-SCDMA模式中与TD-LTE模式实现时隙对齐的常规时隙转换点；Determining the conventional time slot switching point for TD-SCDMA mode and TD-LTE mode to achieve time slot alignment;
从所述常规时隙转换点处推算出该常规时隙转换点之前的N个子帧属于同一个TD-LTE半帧，所述TD-LTE半帧中且常规时隙转换点所在的时间之前是所述检测位置。It is deduced from the normal time slot conversion point that the N subframes before the normal time slot conversion point belong to the same TD-LTE half frame, and the time before the normal time slot conversion point in the TD-LTE half frame is The detection position.
由于TD-SCDMA模式的常规时隙转换点UDSP与TD-LTE中的常规时隙转换点UDSP是对齐的，因此，可以基于这一常规时隙转换点UDSP推算出5ms半帧所包括的SF0、特殊子帧、SF1、SF2和SF3，假设TD-LTE中时隙配置格式为[DSUDD]，表明在UDSP前面有N=3个子帧，后面有5-N=2个子帧属于同一个TD-LTE半帧。Since the conventional time slot switching point UDSP in TD-SCDMA mode is aligned with the conventional time slot switching point UDSP in TD-LTE, the SF0, Special subframes, SF1, SF2 and SF3, assuming that the time slot configuration format in TD-LTE is [DSUDD], it indicates that there are N=3 subframes in front of UDSP, and 5-N=2 subframes in the back belong to the same TD-LTE half frame.
检测位置即是指TD-LTE半帧中且常规时隙转换点UDSP所在的时间之前的某一个时刻，该检测位置表明，是在所述TD-LTE半帧中且UDSP所在的时间之前，开始测量TD-LTE模式的至少一个参数。The detection position refers to a certain moment in the TD-LTE half frame and before the time where the conventional time slot conversion point UDSP is located. The detection position indicates that it is in the TD-LTE half frame and before the time where the UDSP is located. At least one parameter of the TD-LTE mode is measured.
在一个优选实施例中，在第二通信模式的所述检测位置处开始检测所述参数，具体包括：In a preferred embodiment, starting to detect the parameter at the detection position in the second communication mode includes:
设置TD-LTE模式的TDD转换开关为接收状态，接收至少一个参数对应的信号。Set the TDD switch of the TD-LTE mode to the receiving state, and receive a signal corresponding to at least one parameter.
在一个优选实施例中，设置TD-LTE模式的TDD转换开关为接收状态，接收至少一个参数对应的信号，具体包括：In a preferred embodiment, the TDD switch of the TD-LTE mode is set to the receiving state, and the signal corresponding to at least one parameter is received, specifically including:
在所述常规时隙转换点所在的时间之前的N毫秒打开TDD开关，在SF0的时隙1接收物理广播信道信号或者参考信号；Turn on the TDD switch N milliseconds before the time where the conventional time slot transition point is located, and receive the physical broadcast channel signal or reference signal in time slot 1 of SF0;
在所述常规时隙转换点所在的时间之前N毫秒打开TDD开关，在SF0的时隙1的辅同步信号，获取辅同步信号的接收功率；Turn on the TDD switch N milliseconds before the time where the conventional time slot transition point is located, and obtain the received power of the secondary synchronization signal for the secondary synchronization signal in time slot 1 of SF0;
在所述常规时隙转换点所在的时间之前N-1毫秒打开TDD开关，截取主同步信号，获取主同步信号的接收功率。Turn on the TDD switch N-1 milliseconds before the time where the normal time slot transition point is located, intercept the main synchronization signal, and obtain the received power of the main synchronization signal.
在一个应用场景中，假设UE处于TD-SCDMA模式的连接态(Connected)，TD-LTE模式此时可以是Idle，DRX或连接态。In an application scenario, assuming that the UE is in the connected state (Connected) of the TD-SCDMA mode, the TD-LTE mode may be in the Idle, DRX or connected state at this time.
第1步，UE获得TD-SCDMA模式的帧结构和时隙配比，从而确认出常规时隙转换点，为区别TD-LTE模式的时隙转换点，此处TD-SCDMA模式的常规时隙转换点称为第一UDSP。In the first step, the UE obtains the frame structure and time slot ratio of the TD-SCDMA mode, thereby confirming the regular time slot transition point, in order to distinguish the time slot transition point of the TD-LTE mode, here the regular time slot of the TD-SCDMA mode The conversion point is called the first UDSP.
第2步，UE获得TD-LTE模式的帧结构以和时隙配比，从第一UDSP推算出TD-LTE模式的5ms半帧的位置，5ms半帧中包括：SF0、特殊子帧、SF1、SF2和SF3。Step 2: The UE obtains the frame structure of the TD-LTE mode to match the time slot, and calculates the position of the 5ms half-frame of the TD-LTE mode from the first UDSP. The 5ms half-frame includes: SF0, special subframe, SF1 , SF2 and SF3.
