请参阅图1，图1示意性示出了根据本申请的一个实施例的信号碰撞处理方法的流程图。如图1所示，该信号碰撞处理方法可以包括：步骤S110～步骤S140。Please refer to FIG. 1 , which schematically shows a flow chart of a signal collision processing method according to an embodiment of the present application. As shown in Figure 1, the signal collision processing method may include: steps S110 to S140.

步骤S110：基站获取终端的目标小区的物理小区标识，根据物理小区标识计算目标小区的小区参考信号对应的一类空间位置。Step S110: The base station obtains the physical cell identity of the terminal's target cell, and calculates a type of spatial location corresponding to the cell reference signal of the target cell based on the physical cell identity.

步骤S120：基站向终端下发用于指示信号避让的目标指令。Step S120: The base station issues a target command for instructing signal avoidance to the terminal.

步骤S130：终端基于一类空间位置和解调参考信号对应的二类空间位置计算解调参考信号和小区参考信号之间的碰撞位置。Step S130: The terminal calculates the collision position between the demodulation reference signal and the cell reference signal based on the first-class spatial position and the second-class spatial position corresponding to the demodulation reference signal.

步骤S140：终端调整碰撞位置中的解调参考信号的二类空间位置。Step S140: The terminal adjusts the Class II spatial position of the demodulation reference signal in the collision position.

实施图1所示的方法，可以基于小区参考信号对应的一类空间位置和解调参考信号对应的二类空间位置计算出碰撞位置，并根据碰撞位置调整解调参考信号的二类空间位置，以处理信号碰撞的问题，在DSS场景下，可以有利于提升信道容量和覆盖能力。By implementing the method shown in Figure 1, the collision position can be calculated based on the first-class spatial position corresponding to the cell reference signal and the second-class spatial position corresponding to the demodulation reference signal, and the second-class spatial position of the demodulation reference signal can be adjusted according to the collision position. To deal with the problem of signal collision, in DSS scenarios, it can help improve channel capacity and coverage capabilities.

下面，对于本示例实施方式的上述步骤进行更加详细的说明。Below, the above-mentioned steps of this exemplary embodiment will be described in more detail.

在DSS场景下NR下行控制信道(PDCCH)通常需要规避LTE CRS符号，现有技术一般是在没有LTE CRS信号所在的OFDM符号2配置NR PDCCH，舍弃了在OFDM符号1处配置NR PDCCH，但是在OFDM符号2配置NR PDCCH容易导致NR PDCCH容量较小。本申请可以步骤S110～步骤S140实现在不减少NR PDCCH容量的基础上解决搜索空间中小区参考信号和解调参考信号碰撞的问题。In DSS scenarios, the NR downlink control channel (PDCCH) usually needs to avoid LTE CRS symbols. The existing technology generally configures the NR PDCCH at OFDM symbol 2 where there is no LTE CRS signal, and abandons configuring the NR PDCCH at OFDM symbol 1. However, in OFDM symbol 2 configuration of NR PDCCH can easily lead to smaller NR PDCCH capacity. This application can solve the problem of collision between the cell reference signal and the demodulation reference signal in the search space without reducing the NR PDCCH capacity through steps S110 to S140.

在步骤S110中，基站获取终端的目标小区的物理小区标识，根据物理小区标识计算目标小区的小区参考信号对应的一类空间位置。In step S110, the base station obtains the physical cell identity of the terminal's target cell, and calculates a type of spatial location corresponding to the cell reference signal of the target cell based on the physical cell identity.

具体地，目标小区的物理小区标识(Physical Cell Identifier，PCI)用于在长期演进(LTE)中终端区分不同小区的无线信号。LTE***提供504个PCI，和TD-SCDMA***的128个扰码概念类似，网管配置时，为小区配置0～503之间的一个号码。LTE小区搜索流程中通过检索主同步序列(PSS)辅同步序列(SSS)以确定具体的小区ID。Specifically, the Physical Cell Identifier (PCI) of the target cell is used by the terminal to distinguish wireless signals of different cells in Long Term Evolution (LTE). The LTE system provides 504 PCIs, which are similar in concept to the 128 scrambling codes of the TD-SCDMA system. During network management configuration, configure a number between 0 and 503 for the cell. In the LTE cell search process, the primary synchronization sequence (PSS) and secondary synchronization sequence (SSS) are retrieved to determine the specific cell ID.

其中，目标小区的小区参考信号对应的一类空间位置可以包括一个或多个PDCCH的搜索空间中的位置。其中，NR下行控制信道(PDCCH)承载的是DCI(Downlink Control Information)，包含一个或多个终端(UE)上的资源分配和其他的控制信息，在一个子帧内，可以包含多个PDCCH。每个PDCCH使用一个或多个控制信道元素(Control Channel Elements，CCE)进行传输，其中每个CCE对应9个REG，1个REG等效于4个RE)。1个REG由位于同一OFDM符号上的4个或6个相邻的一类空间位置(RE)组成。The type of spatial location corresponding to the cell reference signal of the target cell may include one or more locations in the search space of the PDCCH. Among them, the NR downlink control channel (PDCCH) carries DCI (Downlink Control Information), including resource allocation and other control information on one or more terminals (UE). Within a subframe, it can contain multiple PDCCHs. Each PDCCH uses one or more Control Channel Elements (CCE) for transmission, where each CCE corresponds to 9 REGs, and 1 REG is equivalent to 4 REs). 1 REG consists of 4 or 6 adjacent spatial locations (REs) of a type located on the same OFDM symbol.

针对PDCCH的搜索空间，举例来说，请参阅表1，PDCCH的搜索空间可以为整体空间的其中一部分，如，第二列和第三列。在整体空间中还可以包括其他信道的搜索空间，本申请实施例不作限定。For the search space of PDCCH, for example, please refer to Table 1. The search space of PDCCH can be a part of the overall space, such as the second column and the third column. The overall space may also include search spaces for other channels, which is not limited in this embodiment of the present application.

表1Table 1

其中，第一列NR PDCCH可以对应于OFDM符号1，第二列NR PDCCH可以对应于OFDM符号2。Among them, the first column of NR PDCCH may correspond to OFDM symbol 1, and the second column of NR PDCCH may correspond to OFDM symbol 2.

在表1中，LTE CRS占用的一类空间位置可以处于PDCCH的搜索空间中也可以未处于PDCCH的搜索空间中，LTE CRS占用的一类空间位置的行距可以为预先设定的，同理，DMRS占用的二类空间位置的行距也可以为预先设定的。当NR PDCCH与LTE CRS发生碰撞时，一般通过将NR PDCCH打孔进行规避，通常不会造成较大的损失。但是，若NR PDCCH DMRS与LTE CRS发生碰撞时(表示为表1中第八行第二列)，对DMRS进行打孔会影响NR PDCCH信道估计精度，解调性能，会造成较大的损失，此时，可以通过步骤S110～步骤S140解决信号碰撞的问题。In Table 1, the first type of spatial location occupied by LTE CRS may be in the search space of PDCCH or not in the search space of PDCCH. The row spacing of the first type of spatial location occupied by LTE CRS may be preset. Similarly, The line spacing of the second type space occupied by DMRS can also be preset. When the NR PDCCH collides with the LTE CRS, it is generally avoided by punching the NR PDCCH, which usually does not cause large losses. However, if the NR PDCCH DMRS collides with the LTE CRS (expressed as the eighth row and the second column in Table 1), punching the DMRS will affect the NR PDCCH channel estimation accuracy and demodulation performance, which will cause greater losses. At this time, the problem of signal collision can be solved through steps S110 to S140.

此外，需要说明的是，表1横列可以为14个OFDM符号数、纵列可以为12个子载波数，表1整体上代表一个RB，每一格代表一个RE。下述的表2和表3同理。In addition, it should be noted that the horizontal column of Table 1 can be the number of 14 OFDM symbols, and the vertical column can be the number of 12 subcarriers. Table 1 as a whole represents one RB, and each grid represents one RE. The same applies to Table 2 and Table 3 below.

在步骤S120中，基站向终端下发用于指示信号避让的目标指令。In step S120, the base station issues a target instruction for instructing signal avoidance to the terminal.

具体地，目标指令具体可以用于指示终端存在DMRS与CRS碰撞情况，需要执行信号避让等操作。Specifically, the target command may be used to indicate that the terminal has a collision situation between DMRS and CRS and needs to perform operations such as signal avoidance.

在步骤S130中，终端基于一类空间位置和解调参考信号对应的二类空间位置计算解调参考信号和小区参考信号之间的碰撞位置。In step S130, the terminal calculates the collision position between the demodulation reference signal and the cell reference signal based on the first-class spatial position and the second-class spatial position corresponding to the demodulation reference signal.

具体地，解调参考信号对应的二类空间位置可以包括一个或多个PDCCH的搜索空间中的位置。二类空间位置和一类空间位置可以存在重叠也可以不存在重叠。在碰撞位置中，二类空间位置和一类空间位置重叠。Specifically, the second-class spatial position corresponding to the demodulation reference signal may include one or more positions in the search space of the PDCCH. The second type of spatial location and the first type of spatial location may or may not overlap. In the collision position, the second-class spatial position and the first-class spatial position overlap.

在步骤S140中，终端调整碰撞位置中的解调参考信号的二类空间位置。In step S140, the terminal adjusts the Class II spatial position of the demodulation reference signal in the collision position.

具体地，终端调整碰撞位置中的解调参考信号的二类空间位置，包括：可以将碰撞位置中的解调参考信号的二类空间位置向上/向下调整预设数量(如，1)个位置。举例来说，在表1的基础上，执行步骤S110～步骤S140，可以得到表2。Specifically, the terminal adjusts the Class II spatial position of the demodulation reference signal in the collision position, including: adjusting the Class II spatial position of the demodulation reference signal in the collision position upward/downward by a preset number (eg, 1) Location. For example, based on Table 1, step S110 to step S140 are executed to obtain Table 2.

表2Table 2

在表2中，碰撞位置中的解调参考信号的二类空间位置被向上调整了1位，调整后的解调参考信号的二类空间位置处于表2的第七行第二列，这样可以避免和LTE CRS发送碰撞。In Table 2, the second-class spatial position of the demodulation reference signal in the collision position is adjusted upward by 1 bit. The adjusted second-class spatial position of the demodulation reference signal is in the seventh row and second column of Table 2, so that Avoid collision with LTE CRS transmission.

作为一种可选的实施例，基站获取终端的目标小区的物理小区标识，包括：若下行控制信道的搜索空间以第一方式配置时，基站获取终端的目标小区的物理小区标识。这样可以在搜索空间以第一方式配置，即，高速传输场景下，可以采用移动二类空间位置的方式，规避信号碰撞的问题，有利于提升信道估计的准确性。As an optional embodiment, the base station obtains the physical cell identity of the terminal's target cell, including: if the search space of the downlink control channel is configured in the first manner, the base station obtains the physical cell identity of the terminal's target cell. In this way, the search space can be configured in the first way, that is, in high-speed transmission scenarios, the second type space position can be moved to avoid the problem of signal collision, which is beneficial to improving the accuracy of channel estimation.

For example, based on the example in Table 1, if the method of reducing the Class II space occupied by the demodulation reference signal is used to avoid the signal collision problem, the Class II space occupied by the DMRS in the same NR PDCCH search space as the LTE CRS can be reduced Position removal, that is, can be expressed as Table 3, which can fundamentally solve the signal collision problem.
