技术领域Technical field

本申请涉及通信技术领域，尤其涉及一种通信方法及装置。The present application relates to the field of communication technology, and in particular, to a communication method and device.

背景技术Background technique

在小区搜索(cell search)中，基站可在协议规定的多个频点广播同步信号。相应的，终端设备尝试在这多个频点接收同步信号。终端设备可根据接收到的同步信号，确定小区的信息(如小区标识(identity，ID)、小区的定时信息和频域位置等)。进而，终端设备可根据小区的信息，发起随机接入流程。In cell search, the base station can broadcast synchronization signals at multiple frequencies specified in the protocol. Correspondingly, the terminal device attempts to receive synchronization signals at these multiple frequency points. The terminal device can determine the cell information (such as cell identity (ID), cell timing information and frequency domain location, etc.) based on the received synchronization signal. Furthermore, the terminal device can initiate a random access process based on the cell information.

但部署在非陆地网络(non-terrestrial network，NTN)中的基站，其与终端设备之间的相对速度较大，以及终端设备与基站存在各自的晶振偏差等，可能使得终端设备与基站的工作频点之间存在频率偏差(简称为频偏)，进而可能导致终端设备实际接收同步信号的频点与基站实际发送该同步信号的频点不同。在这种情况下，终端设备可能出现频点混淆的情况，例如终端设备可能将其接收该同步信号的频点错误地作为基站发送该同步信号的频点，那么终端设备向基站发送随机接入的频点可能是终端设备根据基站发送同步信号的频点确定的。可见，在终端设备出现频点混淆的情况下，终端设备会在错误的频点向接入网设备发起随机接入，这可能导致接入网设备无法成功地响应该随机接入，进而可能导致终端设备随机接入失败。However, the relative speed between the base station deployed in the non-terrestrial network (NTN) and the terminal equipment is relatively large, and the terminal equipment and the base station have their own crystal oscillator deviations, etc., which may cause the work of the terminal equipment and the base station to malfunction. There is a frequency deviation (referred to as frequency offset) between frequency points, which may cause the frequency point at which the terminal device actually receives the synchronization signal to be different from the frequency point at which the base station actually sends the synchronization signal. In this case, the terminal device may have frequency confusion. For example, the terminal device may mistakenly use the frequency point at which it receives the synchronization signal as the frequency point at which the base station sends the synchronization signal. Then the terminal device sends a random access signal to the base station. The frequency point may be determined by the terminal device based on the frequency point at which the base station sends the synchronization signal. It can be seen that when frequency confusion occurs in the terminal device, the terminal device will initiate random access to the access network device at the wrong frequency point, which may cause the access network device to be unable to successfully respond to the random access, which may lead to The terminal device failed to access randomly.

发明内容Contents of the invention

本申请实施例提供一种通信方法及装置，用于减少终端设备随机接入失败的情况。Embodiments of the present application provide a communication method and device for reducing random access failures of terminal equipment.

第一方面，本申请实施例提供一种通信方法，该方法可由终端设备执行，或者可由芯片***执行，该芯片***可实现终端设备的功能，为了便于描述，以终端设备执行该通信方法为例。所述方法包括：接收来自接入网设备的第一信息，所述第一信息用于指示第一参数。示例性的，所述第一参数的取值为1、3或5。所述终端设备根据所述第一参数确定所述接入网设备发送同步信号的第一频点，所述第一频点的频率满足如下公式：N*1200千赫兹(kHz)+M*50kHz，其中，N为1至2499中的任一整数，M为所述第一参数。需要说明的是，本申请实施例中的“*”表示乘。In the first aspect, embodiments of the present application provide a communication method. The method can be executed by a terminal device, or can be executed by a chip system. The chip system can realize the functions of the terminal device. For the convenience of description, a terminal device executing the communication method is used as an example. . The method includes: receiving first information from an access network device, where the first information is used to indicate a first parameter. For example, the value of the first parameter is 1, 3 or 5. The terminal device determines the first frequency point at which the access network device sends the synchronization signal according to the first parameter, and the frequency of the first frequency point satisfies the following formula: N*1200 kilohertz (kHz)+M*50kHz , where N is any integer from 1 to 2499, and M is the first parameter. It should be noted that “*” in the embodiment of the present application means multiplying.

在本申请实施例中，终端设备可根据接入网设备指示的第一参数，准确地确定接入网设备发送同步信号的频点，而并不是将接收同步信号的频点直接作为接入网设备发送同步信号的频点，从而减少终端设备产生频点混淆的概率，进而终端设备不会因频点混淆问题而出现随机接入失败的情况，有利于提高终端设备接入小区的成功率，也就相应地避免了因接入小区失败而耽误终端设备的时间，也减少了接入网络的时延。并且，由于接入网设备发送同步信号的频点的频率满足N*1200kHz+M*50kHz，这表示接入网设备发送同步信号的两个频点之间的频率间隔至少是100kHz，即接入网设备发送同步信号的两个频点之间的频率间隔较大，一方面，终端设备与接入网设备之间的频偏大于该频率间隔的可能性较低，这也就降低了终端设备产生频点混淆的可能，另一方面，在第一参数的占用的比特数量固定的情况下，终端设备能够基于第一参数确定相对更大的频率范围内的接入网设备发送同步信号的频点的频率，因此即使终端设备与接入网设备之间的频率偏差较大，在本申请实施例中，终端设备仍能够准确地基于第一参数确定接入网设备实际发送同步信号的频点。此外，第一参数可能的取值仅包括三个，这使得接入网设备可仅采用两个比特便可指示第一参数可能的所有取值，有利于节省第一信息的比特开销，有利于节省接入网设备的传输开销。In this embodiment of the present application, the terminal device can accurately determine the frequency point at which the access network device sends the synchronization signal according to the first parameter indicated by the access network device, instead of directly using the frequency point at which the synchronization signal is received as the access network device. The frequency point at which the device sends the synchronization signal can reduce the probability of frequency confusion in the terminal device, so that the terminal device will not have random access failures due to frequency confusion, which will help improve the success rate of the terminal device accessing the cell. This accordingly avoids The delay in terminal equipment caused by failure to access the cell also reduces the delay in accessing the network. Moreover, since the frequency of the frequency point at which the access network equipment sends the synchronization signal satisfies N*1200kHz+M*50kHz, this means that the frequency interval between the two frequency points at which the access network equipment sends the synchronization signal is at least 100kHz, that is, the access network equipment The frequency interval between the two frequency points where the network equipment sends synchronization signals is relatively large. On the one hand, the possibility that the frequency offset between the terminal equipment and the access network equipment is greater than this frequency interval is low, which also reduces the risk of the terminal equipment. Frequency confusion may occur. On the other hand, when the number of bits occupied by the first parameter is fixed, the terminal device can determine the frequency at which the access network device in a relatively larger frequency range sends the synchronization signal based on the first parameter. Therefore, even if the frequency deviation between the terminal device and the access network device is large, in the embodiment of the present application, the terminal device can still accurately determine the frequency point at which the access network device actually sends the synchronization signal based on the first parameter. . In addition, the possible values of the first parameter only include three, which allows the access network device to use only two bits to indicate all possible values of the first parameter, which is beneficial to saving the bit overhead of the first information and is beneficial to Save transmission overhead of access network equipment.

在一种可能的实施方式中，接入网设备可NTN中的接入网设备，换言之，接入网设备是部署在NTN中的接入网设备。在这种情况下，终端设备可用于接入NTN中的小区。该实施方式中的通信方法可适用于NTN场景。In a possible implementation, the access network device may be an access network device in the NTN.

In this way, the terminal device can obtain the first parameter by parsing the first information, which improves the convenience of the terminal device in obtaining the first parameter. Alternatively, the first information may implicitly indicate the first parameter. For example, the first information may be scrambled using the first parameter, that is, the first parameter belongs to the scrambling code of the first information. In this way, the first parameter may not occupy the bits of the first information, which is beneficial to saving the bit overhead of the first information and the transmission overhead of the access network device.

下面以NTN下的卫星通信***为例，对近地轨道(low earth orbit，LEO)卫星(作为接入网设备)与终端设备之间可能存在的频偏范围进行介绍。The following takes the satellite communication system under NTN as an example to introduce the possible frequency offset range between low earth orbit (LEO) satellites (as access network equipment) and terminal equipment.

LEO卫星绕地球高速运动。假设终端设备静止，LEO卫星的绝对速度最大约为7.7km/s， LEO卫星和终端设备之间的投影速度最大约7.38km/s，可以计算得到终端设备和LEO卫星之间的相对运动造成的频偏最大为24.6百万分之一(ppm)。投影速度是指在单位时间内，LEO卫星与终端设备的直线距离的变化量。以LEO卫星和终端设备之间的频偏为24ppm为例，对于终端设备在不同的频段执行小区搜索的情况下，确定出的最小频点间隔和最大频偏范围的示例可参照下表1所示。LEO satellites orbit the earth at high speed. Assuming that the terminal equipment is stationary, the maximum absolute speed of the LEO satellite is approximately 7.7km/s. The maximum projection speed between the LEO satellite and the terminal equipment is about 7.38km/s. It can be calculated that the maximum frequency deviation caused by the relative motion between the terminal equipment and the LEO satellite is 24.6 parts per million (ppm). The projection speed refers to the change in the straight-line distance between the LEO satellite and the terminal device within unit time. Taking the frequency offset between the LEO satellite and the terminal equipment as an example of 24ppm, when the terminal equipment performs cell search in different frequency bands, examples of the determined minimum frequency point spacing and maximum frequency offset range can be found in Table 1 below. Show.

表1
Table 1

其中，最小频点间隔/2是指最小频点间隔的一半，最小频点间隔是指在一个频段范围下，LEO卫星发送同步信号的两个频点间的最小频率间隔。Among them, the minimum frequency interval/2 refers to half of the minimum frequency interval, and the minimum frequency interval refers to the minimum frequency interval between two frequency points for LEO satellites to send synchronization signals in a frequency band range.

从上表1可知，f_c代指频段，“@X”表示LEO卫星发送同步信号的频点。“±Y@X”可理解为在LEO卫星发送同步信号的频率为X的情况下，LEO卫星和终端设备之间的最大频偏可达到Y，例如，“±72kHz@3GHz”可理解为LEO卫星发送同步信号的频点为3GHz的情况下，LEO卫星和终端设备之间的最大频偏可达到72KHz。As can be seen from Table 1 above, f _c refers to the frequency band, and "@X" indicates the frequency point at which the LEO satellite sends synchronization signals. "±Y@X" can be understood to mean that when the frequency of synchronization signals sent by LEO satellites is When the frequency of satellites sending synchronization signals is 3GHz, the maximum frequency deviation between LEO satellites and terminal equipment can reach 72KHz.

LEO卫星发送同步信号的频点小于3GHz的情况下，终端设备与LEO卫星之间的最大频偏为72kHz，最大频偏大于了该频段范围下的最小频点间隔的一半。在这种情况下，由于终端设备与LEO卫星之间的最大频偏过大，终端设备容易出现频点混淆问题。而终端设备和LEO卫星的晶振偏差等可能会进一步增大终端设备与LEO卫星之间的频偏，导致终端设备更容易出现频点混淆问题。在终端设备出现频点混淆问题之后，终端设备无法准确地确定LEO卫星发送同步信号的频点，进而导致终端设备无法在正确的频点，向LEO卫星发起随机接入。进而，终端设备无法顺利地接入该同步信号对应的小区，这无疑会影响终端设备随机接入的成功率和效率。When the frequency point of the synchronization signal sent by the LEO satellite is less than 3GHz, the maximum frequency deviation between the terminal equipment and the LEO satellite is 72kHz, and the maximum frequency deviation is greater than half of the minimum frequency interval in this frequency band. In this case, because the maximum frequency deviation between the terminal equipment and the LEO satellite is too large, the terminal equipment is prone to frequency confusion. The crystal oscillator deviation between the terminal equipment and the LEO satellite may further increase the frequency offset between the terminal equipment and the LEO satellite, making the terminal equipment more prone to frequency confusion. After the frequency point confusion problem occurs in the terminal equipment, the terminal equipment cannot accurately determine the frequency point at which the LEO satellite sends the synchronization signal, which in turn causes the terminal equipment to be unable to initiate random access to the LEO satellite at the correct frequency point. Furthermore, the terminal equipment cannot smoothly access the cell corresponding to the synchronization signal, which will undoubtedly affect the success rate and efficiency of random access of the terminal equipment.

为此，本申请实施例提供了一种通信方法，在该方法中，接入网设备发送第一信息，第一信息用于指示第一参数。终端设备接收第一信息，根据第一信息指示的第一参数确定接入网设备实际发送同步信号的频点，而不是直接将终端设备接收同步信号的频点作为接入网设备实际发送同步信号的频点，从而减少终端设备产生频点混淆的问题，有利于提高终端设备随机接入的成功率。To this end, embodiments of the present application provide a communication method, in which the access network device sends first information, and the first information is used to indicate the first parameter. The terminal device receives the first information, and determines the frequency point at which the access network device actually sends the synchronization signal based on the first parameter indicated by the first information, instead of directly taking the frequency point at which the terminal device receives the synchronization signal as the frequency point at which the access network device actually sends the synchronization signal. frequency points, thereby reducing the frequency confusion problem of terminal equipment and improving the success rate of random access of terminal equipment.

需要说明的是，本申请实施例中的通信方法可适用于终端设备进行小区初始搜索(initial cell search)(简称为小区初搜)的场景。小区初搜是指终端设备开机后进行的小区搜索。或者，本申请实施例提供的通信方法也适用于小区初始接入的场景。小区初始接入是指终端设备在尚未接入过任何小区情况下的接入场景。It should be noted that the communication method in the embodiment of the present application can be applied to the scenario where the terminal device performs initial cell search (referred to as initial cell search).

S301，接入网设备确定第一参数，第一参数用于确定接入网设备发送同步信号的第一频点。S301. The access network device determines a first parameter. The first parameter is used to determine a first frequency point at which the access network device sends a synchronization signal.

示例性的，所述第一频点的频率满足如下公式：N*1200kHz+M*50kHz。其中，N为1至2499中的任一整数，M表示第一参数。可选的，M可为1、3或5。For example, the frequency of the first frequency point satisfies the following formula: N*1200kHz+M*50kHz. Among them, N is any integer from 1 to 2499, and M represents the first parameter. Optional, M can be 1, 3 or 5.

在本申请实施例中的频率可理解为频点的具体取值，或者频点也可称为频率。The frequency in the embodiment of this application can be understood as the specific value of the frequency point, or the frequency point can also be called frequency.

第一频点为接入网设备实际发送同步信号的频点。同步信号的含义可参照前文。第一频点的频率需满足如下公式(2)：
N*1200kHz+M*50kHz (2)The first frequency point is the frequency point at which the access network equipment actually sends the synchronization signal. The meaning of the synchronization signal can be referred to the previous article. The frequency of the first frequency point needs to satisfy the following formula (2):
N*1200kHz+M*50kHz (2)

其中，N为1至2499中的任一整数，M为所述第一参数，公式(2)可被预配置在接入网设备中。在一种可能的实施方式中，第一频点属于低频范围。可选的，低频范围的上限小于3GHz。Wherein, N is any integer from 1 to 2499, M is the first parameter, and formula (2) can be pre-configured in the access network device. In a possible implementation, the first frequency point belongs to a low frequency range. Optional, the upper limit of the low frequency range is less than 3GHz.

在一种可能的实施方式中，接入网设备可在同步栅格中(synchronization raster)的多个频点广播同步信号。本申请实施例中的第一频点为同步栅格中的任一个频点。同步栅格包括接入网设备可能发送同步信号的频点。因此，同步栅格中的任一频点的频率皆可根据公式(2)获取。In a possible implementation, the access network device may broadcast synchronization signals at multiple frequency points in a synchronization raster. The first frequency point in the embodiment of the present application is any frequency point in the synchronization grid. The synchronization grid includes frequency points where access network equipment may send synchronization signals. Therefore, the frequency of any frequency point in the synchronization grid can be determined according to Obtained from formula (2).

例如，一种在低频范围下的同步栅格的划分方式如下表3所示。For example, a synchronization grid division method in the low frequency range is shown in Table 3 below.

表3
table 3

其中，“N＝1:2499”表示N的取值为1到2499中的任一整数。Among them, "N=1:2499" means that the value of N is any integer from 1 to 2499.

在本申请实施例以接入网设备确定在第一频点发送同步信号为例进行介绍。在这种假设关系下，接入网设备也就确定该第一频点的第一参数，即公式(2)中的M。例如，接入网设备确定第一频点的频率为1250kHz，也就确定了第一参数为1，即M＝1。In the embodiment of this application, the access network device determines to send the synchronization signal at the first frequency point as an example for introduction. Under this assumed relationship, the access network device also determines the first parameter of the first frequency point, that is, M in formula (2). For example, the access network equipment determines that the frequency of the first frequency point is 1250 kHz, and thus determines that the first parameter is 1, that is, M=1.

S302，接入网设备发送第一信息，第一信息用于指示第一参数。S302. The access network device sends first information, where the first information is used to indicate the first parameter.

示例性的，所述接入网设备可以采用广播的方式发送第一信息。在本申请实施例中是以终端设备接收来自接入网设备的第一信息为例进行介绍。For example, the access network device may send the first information in a broadcast manner. In the embodiment of this application, the terminal device receives the first information from the access network device as an example for introduction.

示例性的，所述第一信息可为***信息，例如，主信息块(master indication block，MIB)或***信息块1(system information block type1，SIB1)。For example, the first information may be system information, such as master information block (master information block, MIB) or system information block 1 (system information block type 1, SIB1).

示例性的，第一信息可采用两个比特指示第一参数，例如，这两个比特的取值为00，表示第一参数为1；这两个比特的取值为01，表示第一参数为3；这两个比特的取值为10，表示第一参数为5。For example, the first information may use two bits to indicate the first parameter. For example, the value of these two bits is 00, indicating that the first parameter is 1; the value of these two bits is 01, indicating that the first parameter is is 3; the value of these two bits is 10, indicating that the first parameter is 5.

终端设备接收第一信息后，执行S303，即终端设备根据第一信息中的第一参数确定接入网设备发送同步信号的第一频点。After receiving the first information, the terminal device executes S303, that is, the terminal device determines the first frequency point at which the access network device sends the synchronization signal according to the first parameter in the first information.

示例性的，终端设备接收第一信息后，可以通过解析的方式获取第一参数。终端设备根据上述第一参数和上述公式(2)，从而获得接入网设备发送该同步信号的第一频点。其中，上述公式(2)可被预配置在终端设备中，例如，上述公式(2)可由协议规定在终端设备中。For example, after receiving the first information, the terminal device can obtain the first parameter through analysis. The terminal device obtains the first frequency point at which the access network device sends the synchronization signal based on the above first parameter and the above formula (2). The above formula (2) can be pre-configured in the terminal device. For example, the above formula (2) can be specified in the terminal device by a protocol.

终端设备在根据第一参数和上述公式(2)，确定第一频点时，还需确定上述公式(2)中的N。When the terminal device determines the first frequency point based on the first parameter and the above formula (2), it also needs to determine N in the above formula (2).

示例性的，终端设备可根据终端设备实际接收同步信号的频点，确定上述公式(2)中的N。在本申请实施例中，以终端设备在第二频点接收到该同步信号为例。基于这种假设关系，终端设备可根据第二频点确定上述公式(2)中的N。For example, the terminal device may determine N in the above formula (2) based on the frequency point at which the terminal device actually receives the synchronization signal. In this embodiment of the present application, it is taken as an example that the terminal device receives the synchronization signal at the second frequency point. Based on this assumed relationship, the terminal device can determine N in the above formula (2) according to the second frequency point.

本申请实施例中的第二频点也属于同步栅格中的一个频点，因此终端设备可根据上述公式(2)获取第二频点的频率。The second frequency point in the embodiment of the present application also belongs to a frequency point in the synchronization grid, so the terminal device can obtain the frequency of the second frequency point according to the above formula (2).

如果终端设备与接入网设备实际之间存在较大的频偏，终端设备实际接收同步信号的频点与接入网设备实际发送同步信号的频点不同，即第一频点和第二频点不同。结合前文的内容可知，由于终端设备与接入网设备之间因相对运动造成的最大频偏是72kHz，以及终端设备和接入网设备各自的晶振偏差，而一般晶振偏差相对较小，因此终端设备与接入网设备之间的可能的最大频偏是72kHz左右，也就是说，第一频点和第二频点之间的最大的频率间隔也是72kHz左右，而获取第一频点的频率的公式中N的取值与获取第二频点的频率的公式中N的取值不同的情况下，第一频点和第二频点之间的频率间隔至少是1200kHz，这超过了终端设备与接入网设备之间的可能的最大频偏。因此获取第一频点的频率的公式中N的取值与获取第二频点的频率的公式中N应当是相同的。If there is actually a large frequency offset between the terminal equipment and the access network equipment, the frequency point at which the terminal equipment actually receives the synchronization signal is different from the frequency point at which the access network equipment actually sends the synchronization signal, that is, the first frequency point and the second frequency point. A little different. Based on the previous content, it can be seen that since the maximum frequency deviation caused by relative motion between the terminal equipment and the access network equipment is 72kHz, as well as the respective crystal oscillator deviations of the terminal equipment and the access network equipment, and the general crystal oscillator deviation is relatively small, so the terminal The possible maximum frequency deviation between the device and the access network device is about 72kHz. That is to say, the maximum frequency interval between the first frequency point and the second frequency point is also about 72kHz, and the frequency of the first frequency point is obtained. When the value of N in the formula is different from the value of N in the formula for obtaining the frequency of the second frequency point, the frequency interval between the first frequency point and the second frequency point is at least 1200kHz, which exceeds the terminal equipment The maximum possible frequency offset from the access network equipment. Therefore, the value of N in the formula for obtaining the frequency of the first frequency point and the value of N in the formula for obtaining the frequency of the second frequency point should be the same.

例如，第二频点的频率为1350kHz，终端设备根据上述获取第二频点的频率公式确定 N为1。因此，第一信息指示的第一参数为5，终端设备根据上述公式(2)，确定第一频点的频率：(1*1200+5*50)＝1450kHz。For example, the frequency of the second frequency point is 1350kHz, and the terminal device determines it according to the above frequency formula for obtaining the second frequency point. N is 1. Therefore, the first parameter indicated by the first information is 5, and the terminal device determines the frequency of the first frequency point according to the above formula (2): (1*1200+5*50)=1450kHz.

Moreover, since the first parameter is used to determine a frequency in the synchronization grid, and the interval between any two frequencies in the synchronization grid is at least 100KHz, this is beneficial to reducing the possibility of frequency point confusion generated by the terminal device. sex. Since the problem of frequency point confusion of terminal equipment is avoided, it is also possible to avoid the failure of terminal equipment to access the cell due to frequency point confusion, which is beneficial to improving the success rate and efficiency of terminal equipment access. Moreover, since the access network device only needs to indicate the first parameter in the above formula (2), the value of the first parameter is smaller, so that the first parameter occupies fewer bits, which is beneficial to saving the bit overhead of the first information.

例如，MIB可被承载在同步信号的PBCH上。For example, the MIB may be carried on the PBCH of the synchronization signal.

MIB的预留字段(reserve bit)可用于指示第一参数。或者，MIB的新增字段可用于指示第一参数。The reserved field (reserve bit) of the MIB can be used to indicate the first parameter. Alternatively, a new field of the MIB may be used to indicate the first parameter.

例如，一种MIB包括如下表4至表6中的所示的信息内容。For example, a MIB includes information content as shown in Tables 4 to 6 below.

示例性的，接入网设备采用MIB的预留字段指示第一参数的情况下，接入网设备可采用MIB中的b4和b3用于指示第一参数。例如，在第一频点为低频范围的情况下，接入网设备采用MIB中的b4和b3可指示第一参数。如此，无需增加MIB的字段，并且，第一频点无论是属于低频范围还是高频范围，MIB中的b4和b3均可指示相应的信息，使得MIB中的b4和b3可被充分利用。For example, when the access network device uses the reserved field of the MIB to indicate the first parameter, the access network device may use b4 and b3 in the MIB to indicate the first parameter. For example, when the first frequency point is in a low frequency range, the access network device may use b4 and b3 in the MIB to indicate the first parameter. In this way, there is no need to add fields in the MIB, and whether the first frequency point belongs to the low-frequency range or the high-frequency range, b4 and b3 in the MIB can indicate corresponding information, so that b4 and b3 in the MIB can be fully utilized.

例如，b4b3＝00，表示第一参数为1，即M＝1；b4b3＝01，表示第一参数为3，即M＝3；b4b3＝10，表示第一参数为5，即M＝5。For example, b4b3=00 means that the first parameter is 1, that is, M=1; b4b3=01 means that the first parameter is 3, that is, M=3; b4b3=10 means that the first parameter is 5, that is, M=5.

Alternatively, the access network device may also use the reserved field corresponding to the 31st bit in the MIB, and b4 in the MIB to indicate the first parameter. Alternatively, the access network device may also use the reserved field corresponding to the 31st bit in the MIB, and b3 in the MIB to indicate the first parameter.

其中，MIB可显式地指示第一参数，例如，MIB包括第一参数。或者，MIB可隐式地指示第一参数，例如，MIB的扰码包括第一参数，具体例如，MIB中的DMRS采用同步信号的索引进行加扰，再采用第一参数进行加扰，这样在不增加MIB占用的比特数的情况下，还能指示第一参数。The MIB may explicitly indicate the first parameter, for example, the MIB includes the first parameter. Alternatively, the MIB may indicate the first parameter implicitly. For example, the scrambling code of the MIB includes the first parameter. Specifically, for example, the DMRS in the MIB uses the index of the synchronization signal for scrambling, and then uses the first parameter for scrambling. In this way, The first parameter can also be indicated without increasing the number of bits occupied by the MIB.

S403，终端设备在第二频点接收同步信号。S403: The terminal device receives the synchronization signal at the second frequency point.

理论上接入网设备在第一频点发送该同步信号，终端设备也应在第一频点接收该同步信号。但由于终端设备和接入网设备之间的相对速度、终端设备的晶振偏差以及接入网设备的晶振偏差等原因，可能出现终端设备在与第一频点不同的频点接收该同步信号。在本申请实施例中，以终端设备在第二频点接收同步信号为例。第二频点和第一频点可能不同，也可能相同。其中，第二频点与上述同步栅格中的一个频率对应。Theoretically, the access network equipment sends the synchronization signal at the first frequency point, and the terminal equipment should also receive the synchronization signal at the first frequency point. However, due to reasons such as the relative speed between the terminal equipment and the access network equipment, the crystal oscillator deviation of the terminal equipment, and the crystal oscillator deviation of the access network equipment, the terminal equipment may receive the synchronization signal at a frequency point different from the first frequency point. In this embodiment of the present application, the terminal device receives the synchronization signal at the second frequency point as an example. The second frequency point and the first frequency point may be different or the same. The second frequency point corresponds to a frequency in the above-mentioned synchronization grid.

The terminal device can send the second information according to the first frequency point. The second information is a random access message, for example, message 1 (message1, msg1) or msgA in the random access process. The second information may be used to indicate the random access preamble. The second information may be carried on a random access channel (RACH).

例如，终端设备可在第一频点发送第二信息。For example, the terminal device may send the second information at the first frequency point.

或者例如，终端设备可基于第一频点，确定发送第二信息的频点，并在确定出的第二信息的频点，发送第二信息。其中，基于第一频点确定发送第二信息的频点的方式可被预配置在终端设备中。Or for example, the terminal device may determine the frequency point to send the second information based on the first frequency point, and send the second information at the determined frequency point of the second information. Wherein, the method of determining the frequency point for sending the second information based on the first frequency point may be pre-configured in the terminal device.

可选的，基于第一频点确定发送第二信息的频点的方式为基于第一频移，对第一频点的频率进行修正，以获得发送第二信息的频率。第一频移可以是终端设备从接入网设备接收的，第一频移被预配置在终端设备中，或者第一频移是终端设备自行确定的，本申请实施例对此不做限定。Optionally, the method of determining the frequency point for sending the second information based on the first frequency point is to modify the frequency of the first frequency point based on the first frequency shift to obtain the frequency for sending the second information. The first frequency shift may be received by the terminal device from the access network device, the first frequency shift may be preconfigured in the terminal device, or the first frequency shift may be determined by the terminal device itself, which is not limited in the embodiments of this application.

例如，第一频点的频率为1250kHz，第一频移为70kHz，因此终端设备确定发送第二信息的频率为(1250-70)kHz＝1180kHz。For example, the frequency of the first frequency point is 1250 kHz, and the first frequency shift is 70 kHz. Therefore, the terminal device determines that the frequency at which the second information is sent is (1250-70) kHz = 1180 kHz.

作为一个示例，S405为可选的步骤，在图4中以虚线示意。As an example, S405 is an optional step, illustrated by a dotted line in Figure 4 .

进一步地，终端设备可从接入网设备接收响应信息，该响应信息用于表示接入网设备已接收第二信息。终端设备还可继续与接入网设备进行通信，进而接入该同步信号对应的小区，以完成小区接入。如果终端设备没有成功接入该同步信号对应的小区，则可重复上述图4所示的流程示意图，直到终端设备成功接入小区。Further, the terminal device may receive response information from the access network device, where the response information is used to indicate that the access network device has received the second information. The terminal equipment can also continue to communicate with the access network equipment, and then access the cell corresponding to the synchronization signal to complete cell access. If the terminal device fails to successfully access the cell corresponding to the synchronization signal, the schematic flow chart shown in Figure 4 can be repeated until the terminal device successfully accesses the cell.

在本申请实施例中，接入网设备可利用MIB指示第一参数，终端设备可在接收MIB之后，确定接入网设备发送同步信号的频点，从而避免频率混淆的问题，使得终端设备可顺利地向接入网设备发送第二信息，有利于提高终端设备接入小区的成功率和效率。并且，无需接入网设备向终端设备发送专用消息以指示第一参数，不会额外增加接入网设备与终端设备之间的交互次数。另外，同步信号包括用于指示第一参数的MIB，使得终端设备在接收同步信号之后，便可及时地确定出接入网设备实际发送同步信号的频点。In the embodiment of the present application, the access network device can use the MIB to indicate the first parameter, and the terminal device can determine the frequency point at which the access network device sends the synchronization signal after receiving the MIB, thereby avoiding the problem of frequency confusion and allowing the terminal device to Smoothly sending the second information to the access network device is conducive to improving the success rate and efficiency of the terminal device accessing the cell. Moreover, there is no need for the access network device to send a dedicated message to the terminal device to indicate the first parameter, and the number of interactions between the access network device and the terminal device will not be additionally increased. In addition, the synchronization signal includes a MIB used to indicate the first parameter, so that after receiving the synchronization signal, the terminal device can promptly determine the frequency point at which the access network device actually sends the synchronization signal.
