一种接入信号的发送方法、接收方法及装置A kind of transmission method, reception method and device of access signal

技术领域technical field

本申请涉及无线通信领域，尤其涉及一种接入信号的发送方法、接收方法及装置。The present application relates to the field of wireless communication, and in particular, to a method and apparatus for sending, receiving, and receiving an access signal.

背景技术Background technique

物联网(internet of things，IoT)是“物物相连的互联网”。在IoT中，物品与物品之间能够进行信息交换和通信。因此，IoT的应用十分广泛。例如，IoT可以应用于智能电网、智能农业、智能交通、智能家居以及环境检测等各个方面。The Internet of Things (IoT) is the "Internet of Things Connected". In the IoT, information exchange and communication can take place between objects. Therefore, the application of IoT is very extensive. For example, IoT can be applied to various aspects such as smart grid, smart agriculture, smart transportation, smart home, and environmental detection.

IoT的这种通信方式也可以称为机器类通信(machine type communications，MTC)。MTC的节点可以称为MTC终端设备。MTC终端设备与普通终端设备(例如，新无线(new radio，NR)***中的终端设备，或长期演进(long term evolution，LTE)***中的终端设备)有很大不同。例如，相对于普通终端设备，MTC终端设备的电池寿命更长，复杂度更低，成本也更低。因此，MTC终端设备的带宽更窄，传输效率也更低。This communication method of IoT can also be called machine type communications (MTC). A node of the MTC may be referred to as an MTC terminal device. An MTC terminal device is very different from a common terminal device (eg, a terminal device in a new radio (NR) system, or a terminal device in a long term evolution (LTE) system). For example, MTC terminal equipment has longer battery life, lower complexity and lower cost than common terminal equipment. Therefore, the bandwidth of the MTC terminal equipment is narrower and the transmission efficiency is also lower.

在通信***中，普通终端设备若要与网络设备通信，需要进行小区搜索。例如，在NR***中，普通终端若要与网络设备通信，会接收同步信号/广播信道块(SS/PBCH block，SSB)，根据SSB获取下行时频同步。通常SSB占用的带宽为3.6MHz或者7.2MHz，而MTC终端设备支持的带宽可能小于3.6MHz。这种带宽小于3.6MHz的终端设备无法接收SSB，因此无法与网络设备通信。In a communication system, if a common terminal device wants to communicate with a network device, it needs to perform a cell search. For example, in an NR system, if an ordinary terminal wants to communicate with a network device, it will receive a synchronization signal/broadcast channel block (SS/PBCH block, SSB), and obtain downlink time-frequency synchronization according to the SSB. Usually, the bandwidth occupied by the SSB is 3.6MHz or 7.2MHz, while the bandwidth supported by the MTC terminal equipment may be less than 3.6MHz. Such terminal equipment with a bandwidth of less than 3.6MHz cannot receive SSB and therefore cannot communicate with network equipment.

一种可能的实现方式，该第三频率位置与该第二频率位置之间的频率间隔大于或等于该第一接入信号在频域上占用的带宽与该第二接入信号在频域上占用的带宽之和的一半。基于上述方法，网络设备可以在第三频率位置上发送第一接入信号，在与第三频率位置间隔大于或等于第一接入信号在频域上占用的带宽与该第二接入信号在频域上占用的带宽之和的一半的频率位置上发送第二接入信号。如此，可以实现带宽较大的终端设备可以接收到第一接入信号，带宽较小的终端设备可以接收到第二接入信号。A possible implementation manner, the frequency interval between the third frequency position and the second frequency position is greater than or equal to the bandwidth occupied by the first access signal in the frequency domain and the second access signal in the frequency domain Half of the sum of the occupied bandwidth. Based on the above method, the network device may send the first access signal at the third frequency position, and the interval between the third frequency position and the third frequency position is greater than or equal to the bandwidth occupied by the first access signal in the frequency domain and the second access signal. The second access signal is sent at a frequency position that is half of the sum of the occupied bandwidths in the frequency domain. In this way, a terminal device with a larger bandwidth can receive the first access signal, and a terminal device with a smaller bandwidth can receive the second access signal.

一种可能的实现方式，该第一频率位置与该第二频率位置之间满足公式：f ₂＝f ₁+O，和/或，f ₂＝f ₁-O；其中，f ₁为该第一频率位置中的一个频率位置，f ₂为该第二频率位置，O满足公式：O＝K ₁/2*scs ₁+K ₂/2*scs ₂；其中，K ₁为该第一接入信号占用的子载波的数量，scs ₁为该第一接入信号占用的子载波的子载波间隔，K ₂为该第二接入信号占用的子载波的数量，scs ₂为该第二接入信号占用的子载波的子载波间隔。基于上述方法，第一终端设备和网络设备可以根据第一频率位置中的一个频率位置确定第二频率位置，实现第二频率位置与第一频率位置中的一个频率位置间隔O。后续，网络设备可以在第二频率位置上发送第二接入信号，第一终端设备可以在第二频率位置上接收第二接入信号，并根据第二接入信号进行时频同步。从上述公式可以看出，在f ₁为第三频率位置的情况下，频率位置间隔O为第一接入信号和第二接入信号在频域上占用的带宽之和的一半，使得网络设备可以实现第一接入信号和第二接入信号在频域上相邻，从而第一接入信号与第二接入信号之间没有资源碎片，不会影响频域资源的分配，可以提高频域资源的使用率。 A possible implementation manner, the first frequency position and the second frequency position satisfy the formula: f ₂ =f ₁ +O, and/or, f ₂ =f ₁ -O; wherein, f ₁ is the first frequency A frequency position in a frequency position, f ₂ is the second frequency position, O satisfies the formula: O=K ₁ /2*scs ₁ +K ₂ /2*scs ₂ ; wherein, K ₁ is the first access The number of sub-carriers occupied by the signal, scs ₁ is the sub-carrier spacing of the sub-carriers occupied by the first access signal, K ₂ is the number of sub-carriers occupied by the second access signal, and scs ₂ is the second access signal The subcarrier spacing of the subcarriers occupied by the signal.

Subsequently, the network device may send the second access signal at the second frequency position, and the first terminal device may receive the second access signal at the second frequency position, and perform time-frequency synchronization according to the second access signal. It can be seen from the above formula that when f ₁ is the third frequency position, the frequency position interval O is half of the sum of the bandwidths occupied by the first access signal and the second access signal in the frequency domain, so that the network device It can realize that the first access signal and the second access signal are adjacent in the frequency domain, so that there is no resource fragmentation between the first access signal and the second access signal, the allocation of frequency domain resources will not be affected, and the frequency domain can be improved.

Based on the above method, the interval between the second frequency position and one of the first frequency positions is greater than or equal to the frequency interval between the fourth frequency position and the fifth frequency position. In the case where f ₁ is the third frequency position, the influence on the scheduling of the SIB1 corresponding to the first access signal can be reduced, and at the same time, the terminal device can be prevented from receiving the second access signal and receiving the SIB1 corresponding to the second access signal or Frequency switching occurs when other system information occurs, thereby reducing the cost and complexity of terminal equipment.

可以理解的，上述表1和表2仅是同步栅格的相关参数的示例，在实际应用中，同步栅格的相关参数还可以是其他形式，不予限制。It can be understood that the above Table 1 and Table 2 are only examples of the relevant parameters of the synchronization grid. In practical applications, the relevant parameters of the synchronization grid may also be in other forms, which are not limited.

终端设备检测到SSB后，会根据SSB获取下行时频同步。终端设备还会根据SSB中的PBCH确定控制资源集合。其中，控制资源集合是用于传输物理下行控制信道(physical downlink control channel，PDCCH)的时频资源。该PDCCH用于调度***信息块类型一(system information block type1，SIB1)。在NR***中，控制资源集合可以称为CORESET(control resource set)。After the terminal device detects the SSB, it will obtain downlink time-frequency synchronization according to the SSB. The terminal device also determines the control resource set according to the PBCH in the SSB. The control resource set is a time-frequency resource used for transmitting a physical downlink control channel (PDCCH). The PDCCH is used to schedule system information block type 1 (system information block type1, SIB1). In the NR system, the control resource set can be called CORESET (control resource set).

终端设备确定控制资源集合后，在控制资源集合上接收PDCCH，并根据PDCCH接收SIB1。如此，终端设备即可根据SIB1接入网络设备。After determining the control resource set, the terminal device receives the PDCCH on the control resource set, and receives the SIB1 according to the PDCCH. In this way, the terminal device can access the network device according to the SIB1.

随着IoT的发展，为了延长终端设备的电池寿命，降低终端设备的复杂度以及降低终端设备的成本，引入了带宽较窄的终端设备。这种终端设备的带宽可能小于SSB占用的带宽，因此无法接收SSB，也无法与网络设备通信。With the development of IoT, in order to prolong the battery life of terminal equipment, reduce the complexity of terminal equipment, and reduce the cost of terminal equipment, terminal equipment with narrow bandwidth is introduced. The bandwidth of such terminal equipment may be smaller than that occupied by the SSB, so it cannot receive the SSB and cannot communicate with the network equipment.

示例性的，以图1A所示的通信***10为NR***为例，子载波间隔为15kHz的情况下，SSB占用的带宽为3.6MHz，子载波间隔为30kHz的情况下，SSB占用的带宽为7.2MHz。而上述带宽较窄的终端设备的带宽有可能小于3.6MHz，例如为2MHz，在这种情况下，上述带宽较窄的终端设备无法接收SSB，因此也无法与网络设备通信。Exemplarily, taking the communication system 10 shown in FIG. 1A as an NR system as an example, when the subcarrier spacing is 15 kHz, the bandwidth occupied by the SSB is 3.6 MHz, and when the subcarrier spacing is 30 kHz, the bandwidth occupied by the SSB is 7.2MHz. The bandwidth of the terminal device with the narrow bandwidth may be less than 3.6MHz, for example, 2MHz. In this case, the terminal device with the narrow bandwidth cannot receive the SSB, and therefore cannot communicate with the network device.

为了解决上述带宽较窄的终端设备无法接收SSB的问题，可以引入一种窄带SSB。该窄带SSB占用的带宽小于宽带SSB占用的带宽。该窄带SSB可能出现的频率位置可以和上述宽带SSB可能出现的频率位置相同。也就是说，窄带SSB采用和宽带SSB相同的同步栅格。如此，带宽较窄的终端设备可以检测窄带SSB，根据窄带SSB获取下行时频同步。In order to solve the problem that the terminal device with narrow bandwidth cannot receive the SSB, a narrowband SSB can be introduced. The bandwidth occupied by the narrowband SSB is smaller than the bandwidth occupied by the wideband SSB. The possible frequency location of the narrowband SSB may be the same as the possible frequency location of the above-mentioned wideband SSB. That is, the narrowband SSB uses the same synchronization grid as the wideband SSB. In this way, a terminal device with a narrow bandwidth can detect the narrowband SSB, and obtain downlink time-frequency synchronization according to the narrowband SSB.

然而，若窄带SSB和宽带SSB采用相同的同步栅格，窄带SSB和宽带SSB之间的频域资源可能小于频域资源的最小调度单位(例如一个资源块(resource block，RB))。在这种情况下，窄带SSB和宽带SSB之间的频域资源会成为资源碎片，影响频域资源的分配。However, if the narrowband SSB and the wideband SSB use the same synchronization grid, the frequency domain resources between the narrowband SSB and the wideband SSB may be smaller than the minimum scheduling unit of the frequency domain resources (for example, a resource block (RB)). In this case, the frequency domain resources between the narrowband SSB and the wideband SSB will become resource fragments, which affects the allocation of frequency domain resources.

示例性的，以窄带SSB和宽带SSB占用的子载波的子载波间隔为30kHz，窄带SSB和宽带SSB的频率位置在0MHz-3000MHz之间，窄带SSB占用6个RB，宽带SSB占用20个RB为例，图1B示出了窄带SSB和宽带SSB在频域上间隔最近的情况下，两种SSB的频率位置。图1B中，箭头所在的位置为网络设备可能发送宽带SSB或者窄带SSB的频域位置。箭头105为网络设备发送宽带SSB的频率位置，箭头106为网络设备发送窄带SSB的频率位置。图1B中，窄带SSB和宽带SSB之间的频域资源为120kHz，120kHz小于1个RB，会影响频域资源分配。Exemplarily, the subcarrier spacing of the subcarriers occupied by the narrowband SSB and the wideband SSB is 30 kHz, the frequency positions of the narrowband SSB and the wideband SSB are between 0MHz and 3000MHz, the narrowband SSB occupies 6 RBs, and the wideband SSB occupies 20 RBs. For example, FIG. 1B shows the frequency positions of the narrowband SSB and the wideband SSB in the case that the narrowband SSB and the wideband SSB are closely spaced in the frequency domain. In FIG. 1B , the position of the arrow is the position in the frequency domain where the network device may transmit the broadband SSB or the narrowband SSB. Arrow 105 is the frequency position where the network device sends the broadband SSB, and arrow 106 is the frequency position where the network device sends the narrowband SSB. In FIG. 1B , the frequency domain resource between the narrowband SSB and the wideband SSB is 120 kHz, and 120 kHz is less than 1 RB, which will affect the frequency domain resource allocation.

步骤301：网络设备确定能够用于发送第一接入信号的第一频率位置。Step 301: The network device determines a first frequency location that can be used to send the first access signal.

其中，网络设备可以为图1A所示通信***10中的网络设备101。第一接入信号包括SSB或同步信号(例如，PSS和/或SSS)。第一接入信号可以是网络设备发送给第一类型终端设备的接入信号。可以理解的，第一接入信号占用的带宽小于或等于第一类型终端设备的带宽。The network device may be the network device 101 in the communication system 10 shown in FIG. 1A . The first access signal includes an SSB or synchronization signal (eg, PSS and/or SSS). The first access signal may be an access signal sent by the network device to the terminal device of the first type. It can be understood that the bandwidth occupied by the first access signal is less than or equal to the bandwidth of the first type of terminal device.

第一频率位置包括一个或多个频率位置。示例性的，第一频率位置有以下三种情况：The first frequency location includes one or more frequency locations. Exemplarily, the first frequency position has the following three situations:

情况1：频率范围为0MHz-3000MHz的情况下，第一频率位置满足公式：f ₁＝N*1200kHz+M*50kHz。其中，N为大于等于1，并且小于等于2499的整数，M为1、3或5。 Case 1: When the frequency range is 0MHz-3000MHz, the first frequency position satisfies the formula: f ₁ =N*1200kHz+M*50kHz. Among them, N is an integer greater than or equal to 1 and less than or equal to 2499, and M is 1, 3 or 5.

示例性的，频率范围为0MHz-3000MHz的情况下，网络设备根据上述公式可以确定出一个或多个频率位置。例如，N＝1，M＝1的情况下，f ₁＝1200kHz+50kHz＝1250kHz。N＝1，M＝3的情况下，f ₁＝1200kHz+3*50kHz＝1350kHz。N＝1，M＝5的情况下，f ₁＝1200kHz+5*50kHz＝1450kHz。 Exemplarily, when the frequency range is 0MHz-3000MHz, the network device can determine one or more frequency positions according to the above formula. For example, when N=1 and M=1, f ₁ =1200kHz+50kHz=1250kHz. When N=1 and M=3, f ₁ =1200kHz+3*50kHz=1350kHz. When N=1 and M=5, f ₁ =1200kHz+5*50kHz=1450kHz.

情况2：频率范围为3000MHz-24250MHz的情况下，第一频率位置满足公式：f ₁＝3000MHz+N*1.44MHz。其中，N为大于等于0，并且小于等于14756的整数。 Case 2: When the frequency range is 3000MHz-24250MHz, the first frequency position satisfies the formula: f ₁ =3000MHz+N*1.44MHz. Among them, N is an integer greater than or equal to 0 and less than or equal to 14756.

示例性的，频率范围为3000MHz-24250MHz的情况下，网络设备根据上述公式可以确定出一个或多个频率位置。例如，N＝0的情况下， f ₁＝3000MHz+0*1.44MHz＝3000MHz。N＝1的情况下，f ₁＝3000MHz+1*1.44MHz＝3001.44MHz。 Exemplarily, when the frequency range is 3000MHz-24250MHz, the network device may determine one or more frequency positions according to the above formula. For example, when N=0, f ₁ =3000MHz+0*1.44MHz=3000MHz. When N=1, f ₁ =3000MHz+1*1.44MHz=3001.44MHz.

情况3：频率范围为24250MHz-52600MHz的情况下，第一频率位置满足公式：f ₁＝24250.08MHz+N*17.28MHz。其中，N为大于等于0，并且小于等于4383的整数。 Case 3: When the frequency range is 24250MHz-52600MHz, the first frequency position satisfies the formula: f ₁ =24250.08MHz+N*17.28MHz. Among them, N is an integer greater than or equal to 0 and less than or equal to 4383.

示例性的，频率范围为24250MHz-52600MHz的情况下，网络设备根据上述公式可以确定出一个或多个频率位置。例如，N＝0的情况下，f ₁＝24250.08MHz+0*17.28MHz＝24250.08MHz。N＝1的情况下，f ₁＝24250.08MHz+1*17.28MHz＝24267.36MHz。 Exemplarily, when the frequency range is 24250MHz-52600MHz, the network device can determine one or more frequency positions according to the above formula. For example, when N=0, f ₁ =24250.08MHz+0*17.28MHz=24250.08MHz. In the case of N=1, f ₁ =24250.08MHz+1*17.28MHz=24267.36MHz.

一种可能的实现方式，网络设备确定了能够用于发送第一接入信号的第一频率位置后，可以在第一频率位置中的第三频率位置上发送第一接入信号。第三频率位置为第一频率位置中的任一频率位置。In a possible implementation manner, after determining the first frequency position that can be used to send the first access signal, the network device may send the first access signal at a third frequency position in the first frequency position. The third frequency position is any one of the first frequency positions.

其中，第三频率位置为第一接入信号占用的子载波中的子载波k ₁的频率位置。其中，k ₁为第一接入信号占用的子载波的编号。k ₁满足：

或者

步骤302：网络设备确定第二频率位置，并在第二频率位置上发送第二接入信号。Step 302: The network device determines a second frequency location, and sends a second access signal at the second frequency location.

其中，第二接入信号包括SSB或同步信号(例如，PSS和/或SSS)。第二接入信号在频域上占用的带宽小于第一接入信号在频域上占用的带宽。例如，第二接入信号在频域上占用的带宽为2MHz。第一接入信号在频域上占用的带宽为3.6MHz。Wherein, the second access signal includes SSB or synchronization signal (eg, PSS and/or SSS). The bandwidth occupied by the second access signal in the frequency domain is smaller than the bandwidth occupied by the first access signal in the frequency domain. For example, the bandwidth occupied by the second access signal in the frequency domain is 2 MHz. The bandwidth occupied by the first access signal in the frequency domain is 3.6 MHz.

第二接入信号可以是网络设备发送给第一类型终端设备，和/或，第二类型终端设备的接入信号。其中，第二类型终端设备的带宽小于第一类型终端设备的带宽。例如，第二类型终端设备的带宽为3MHz。第一类型终端设备的带宽为7.2MHz。可以理解的，第二接入信号占用的带宽小于或等于第二类型终端设备的带宽。The second access signal may be an access signal sent by the network device to the terminal device of the first type and/or to the terminal device of the second type. Wherein, the bandwidth of the terminal device of the second type is smaller than the bandwidth of the terminal device of the first type. For example, the bandwidth of the second type of terminal equipment is 3MHz. The bandwidth of the first type of terminal equipment is 7.2MHz. It can be understood that the bandwidth occupied by the second access signal is less than or equal to the bandwidth of the second type of terminal device.

一种可能的实现方式，第二频率位置为第二接入信号占用的子载波中的子载波k ₂的频率位置。其中，k ₂为第二接入信号占用的子载波的编号，k ₂满足：

或者

K ₂为第二接入信号占用的子载波的数量。 In a possible implementation manner, the second frequency position is the frequency position of the subcarrier k ₂ in the subcarriers occupied by the second access signal. Wherein, k ₂ is the number of the subcarrier occupied by the second access signal, and k ₂ satisfies:

or

K ₂ is the number of subcarriers occupied by the second access signal.

进一步的，子载波k ₂的频率位置指的是子载波k ₂的中心频率。在第二接入信号占用的子载波中，第二接入信号的子载波编号是从0开始按照频率递增或者递减顺序进行编号的。 Further, the frequency position of the sub-carrier k ₂ refers to the center frequency of the sub-carrier k ₂ . Among the subcarriers occupied by the second access signal, the subcarrier numbers of the second access signal are numbered from 0 in an increasing or decreasing order of frequency.

请参考图5，图5为第二频率位置的示意图。图5所示的第二接入信号占用的子载波个数为72。第二频率位置为第二接入信号占用的子载波中的子载波36的频率位置。Please refer to FIG. 5 , which is a schematic diagram of the second frequency position. The number of subcarriers occupied by the second access signal shown in FIG. 5 is 72. The second frequency position is the frequency position of the subcarrier 36 in the subcarriers occupied by the second access signal.

一种可能的实现方式，第二频率位置与第三频率位置位于同一频带(band)的不同位置，并且第二频率位置与第一频率位置中的至少一个频率位置满足设定的条件。其中，第一频率位置中的至少一个频率位置可以是第三频率位置，也可以不是第三频率位置。In a possible implementation manner, the second frequency position and the third frequency position are located at different positions in the same frequency band, and at least one of the second frequency position and the first frequency position satisfies a set condition. Wherein, at least one of the first frequency positions may be the third frequency position, or may not be the third frequency position.

其中，频带可以是一个频率范围(frequency range)。例如在NR***中，定义了两种频率范围，频域范围1(frequency range 1，FR1)和频域范围2(frequency range 2，FR2)。FR1对应410MHz-7125MHz，FR2对应24250MHz–52600MHz。频带也可以是一个工作频带(operating band)。例如NR***中定义了多个工作频带，并进行了编号，编号为n1的工作频带，对应的上行频率为1920MHz-1980MHz，对应的下行频率为2110MHz–2170MHz。The frequency band can be a frequency range. For example, in the NR system, two frequency ranges are defined, frequency range 1 (frequency range 1, FR1) and frequency range 2 (frequency range 2, FR2). FR1 corresponds to 410MHz-7125MHz, and FR2 corresponds to 24250MHz-52600MHz. The frequency band can also be an operating band. For example, multiple working frequency bands are defined and numbered in the NR system. The working frequency band numbered n1 corresponds to an uplink frequency of 1920MHz-1980MHz and a corresponding downlink frequency of 2110MHz to 2170MHz.

一种可能的实现方式，第三频率位置与第二频率位置之间的频率间隔大于或等于第一接入信号在频域上占用的带宽与第二接入信号在频域上占用的带宽之和的一半。A possible implementation manner, the frequency interval between the third frequency position and the second frequency position is greater than or equal to the sum of the bandwidth occupied by the first access signal in the frequency domain and the bandwidth occupied by the second access signal in the frequency domain. and half.

可以理解的，在第三频率位置与第二频率位置之间的频率间隔等于第一接入信号在频域上占用的带宽与第二接入信号在频域上占用的带宽之和的一半的情况下，第一接入信号与第二接入信号在频域上相邻。因此，第一接入信号与第二接入信号之间没有资源碎片，不会影响频域资源的分配，可以提高频域资源的使用率。It can be understood that the frequency interval between the third frequency position and the second frequency position is equal to half of the sum of the bandwidth occupied by the first access signal in the frequency domain and the bandwidth occupied by the second access signal in the frequency domain. In this case, the first access signal and the second access signal are adjacent in the frequency domain. Therefore, there is no resource fragmentation between the first access signal and the second access signal, the allocation of frequency domain resources is not affected, and the utilization rate of frequency domain resources can be improved.

可以理解的，上述设定的条件可以有多种，示例性的，本申请实施例以以下两种条件为例进行介绍。It can be understood that there may be various conditions set above. By way of example, the embodiments of the present application take the following two conditions as examples for introduction.

条件1：第一频率位置与第二频率位置之间满足公式：f ₂＝f ₁+O，和/或，f ₂＝f ₁-O。 Condition 1: The formula: f ₂ =f ₁ +O, and/or f ₂ =f ₁ -O is satisfied between the first frequency position and the second frequency position.

其中，f ₁为第一频率位置中的一个频率位置。f ₂为第二频率位置。O满足公式：O＝K ₁/2*scs ₁+K ₂/2*scs ₂。 Wherein, f ₁ is one of the first frequency positions. f ₂ is the second frequency position. O satisfies the formula: O=K ₁ /2*scs ₁ +K ₂ /2*scs ₂ .

其中，K ₁为第一接入信号占用的子载波的数量。scs ₁为第一接入信号占用的子载波的子载波间隔。K ₂为第二接入信号占用的子载波的数量。scs ₂为第二接入信号占用的子载波的子载波间隔。scs ₁和scs ₂可以相同。 Wherein, K ₁ is the number of subcarriers occupied by the first access signal. scs ₁ is the subcarrier spacing of the subcarriers occupied by the first access signal. K ₂ is the number of subcarriers occupied by the second access signal. scs ₂ is the subcarrier spacing of the subcarriers occupied by the second access signal. scs ₁ and scs ₂ can be the same.

示例性的，以f ₁为6000kHz，K ₁为240，K ₂为72，scs ₁和scs ₂为30kHz为例，O＝240/2*30+72/2*30＝4680kHz，f ₂＝6000+4680＝10680kHz，和/或，f ₂＝6000-4680＝1320kHz。 Exemplarily, taking f ₁ as 6000kHz, K ₁ as 240, K ₂ as 72, and scs ₁ and scs ₂ as 30 kHz, O=240/2*30+72/ ₂ *30=4680kHz, f2=6000 +4680=10680kHz, and/or, f2= _6000-4680 =1320kHz.

可以理解的，f ₁也可以为第三频率位置。在这种情况下，第一接入信号与第二接入信号在频域上相邻。例如，第三频率位置与第二频率位置的关系可以如图6所示。 It can be understood that f ₁ can also be the third frequency position. In this case, the first access signal and the second access signal are adjacent in the frequency domain. For example, the relationship between the third frequency position and the second frequency position may be as shown in FIG. 6 .

可以理解的，对于上述情况1，在f ₂＝f ₁+O的情况下，N为大于等于1，并且小于2499的整数，M为1、3或5；在f ₂＝f ₁-O的情况下，N为大于1，并且小于等于2499的整数，M为1、3或5。对于上述情况2，在f ₂＝f ₁+O的情况下，N为大于等于0，并且小于14756的整数；在f ₂＝f ₁-O的情况下，N为大于0，并且小于等于14756的整数。对于上述情况3，在f ₂＝f ₁+O的情况下，N为大于等于0，并且小于4383的整数；在f ₂＝f ₁-O的情况下，N为大于0，并且小于等于4383的整数。 It can be understood that for the above case 1, in the case of f ₂ =f ₁ +O, N is an integer greater than or equal to 1 and less than 2499, and M is 1, 3 or 5; in the case of f ₂ =f ₁ -O In this case, N is an integer greater than 1 and less than or equal to 2499, and M is 1, 3 or 5. For the above case 2, in the case of f ₂ =f ₁ +O, N is an integer greater than or equal to 0 and less than 14756; in the case of f ₂ =f ₁ -O, N is greater than 0 and less than or equal to 14756 the integer. For the above case 3, in the case of f ₂ =f ₁ +O, N is an integer greater than or equal to 0 and less than 4383; in the case of f ₂ =f ₁ -O, N is greater than 0 and less than or equal to 4383 the integer.

可以理解的，根据图1A中的描述可知，终端设备在检测到接入信号后，会根据接入信号确定接入信号指示的控制资源集合，并在控制资源集合上接收PDCCH，以便根据PDCCH接收SIB1。若该终端设备为第一类型终端设备，则该终端设备的带宽可以同时覆盖接入信号的频率位置，以及接入信号指示的控制资源集合的频率位置。因此，该终端设备检测到接入信号后，不需要切换频率位置即可在接入信号指示的控制资源集合上接收PDCCH。若该终端设备为第二类型终端设备，该终端设备的带宽不能同时覆盖接入信号的频率位置，以及接入信号指示的控制资源集合。因此，该终端设备接收到接入信号后，可能要切换频率之后才能接收到PDCCH，这样会增加终端设备的复杂度，进而会增加终端设备的成本。It can be understood that, according to the description in FIG. 1A , after detecting the access signal, the terminal device will determine the control resource set indicated by the access signal according to the access signal, and receive the PDCCH on the control resource set, so as to receive the PDCCH according to the PDCCH. SIB1. If the terminal device is the first type of terminal device, the bandwidth of the terminal device can cover both the frequency position of the access signal and the frequency position of the control resource set indicated by the access signal. Therefore, after detecting the access signal, the terminal device can receive the PDCCH on the control resource set indicated by the access signal without switching frequency positions. If the terminal device is the second type of terminal device, the bandwidth of the terminal device cannot cover the frequency location of the access signal and the set of control resources indicated by the access signal at the same time. Therefore, after receiving the access signal, the terminal device may need to switch frequencies before receiving the PDCCH, which increases the complexity of the terminal device and further increases the cost of the terminal device.

例如，如图7所示，为第一类型终端设备的带宽与第二类型终端设备的带宽的示意图。图7中，第一类型终端设备的带宽等于第一接入信号指示的控制资源集合占用的带宽。第一类型终端设备的带宽可以同时覆盖第一接入信号的频率位置，以及第一接入信号指示的控制资源集合的频率位置。第二类型终端设备的带宽等于第二接入信号占用的带宽。第二类型终端设备的带宽不能同时覆盖第二接入信号的频率位置，以及第二接入信号指示的控制资源集合的频率位置。在这种情况下，第二类型终端设备接收到第二接入信号后，需要切换频率位置，以使得第二类型终端设备的带宽能够覆盖第二接入信号指示的控制资源集合的频率位置。这样会增加终端设备的复杂度，进而会增加终端设备的成本。若要避免增加终端设备的复杂度，可以通过如下条件2确定第二频率位置。For example, as shown in FIG. 7 , it is a schematic diagram of the bandwidth of the first type of terminal equipment and the bandwidth of the second type of terminal equipment. In FIG. 7 , the bandwidth of the terminal device of the first type is equal to the bandwidth occupied by the control resource set indicated by the first access signal. The bandwidth of the first type of terminal equipment may simultaneously cover the frequency position of the first access signal and the frequency position of the control resource set indicated by the first access signal. The bandwidth of the second type of terminal equipment is equal to the bandwidth occupied by the second access signal. The bandwidth of the second type of terminal equipment cannot cover both the frequency position of the second access signal and the frequency position of the control resource set indicated by the second access signal. In this case, after receiving the second access signal, the second type terminal device needs to switch the frequency position, so that the bandwidth of the second type terminal device can cover the frequency position of the control resource set indicated by the second access signal. This will increase the complexity of the terminal device, which in turn will increase the cost of the terminal device. To avoid increasing the complexity of the terminal device, the second frequency position may be determined through the following condition 2.

条件2：第一频率位置与第二频率位置之间满足公式：f ₂＝f ₁+O+Δ，和/或，f ₂＝f ₁-O-Δ； Condition 2: The first frequency position and the second frequency position satisfy the formula: f ₂ =f ₁ +O+Δ, and/or, f ₂ =f ₁ -O-Δ;

其中，f ₁、f ₂、O的介绍可以参考上述条件1中对应的描述。Δ大于0。 For the introduction of f ₁ , f ₂ , and O, reference may be made to the corresponding descriptions in Condition 1 above. Δ is greater than 0.

示例性的，以f ₁为12250kHz，K ₁为240，K ₂为72，scs ₁和scs ₂为30kHz，Δ为720kHz为例，O＝240/2*30+72/2*30＝4680kHz，f ₂＝12250+4680+720＝17650kHz，和/或，f ₂＝12250-4680-720＝6850kHz。 Exemplarily, taking f ₁ as 12250kHz, K ₁ as 240, K ₂ as 72, scs ₁ and scs ₂ as 30kHz, and Δ as 720kHz, O=240/2*30+72/2*30=4680kHz, f2=12250 ₊ 4680+720=17650kHz, and/or, f2= _{12250-4680-720} =6850kHz.

可以理解的，f ₁也可以为第三频率位置。第三频率位置、第二频率位置、第一接入信号指示的控制资源集合以及第二接入信号指示的控制资源集合在频域的位置可以如图8所示。图8可以看出，第二类型终端设备的带宽能够同时覆盖第二接入信号的频率位置，以及第二接入信号指示的控制资源集合的频率位置。 It can be understood that f ₁ can also be the third frequency position. The positions of the third frequency position, the second frequency position, the control resource set indicated by the first access signal, and the control resource set indicated by the second access signal in the frequency domain may be as shown in FIG. 8 . It can be seen from FIG. 8 that the bandwidth of the second type of terminal equipment can cover both the frequency position of the second access signal and the frequency position of the control resource set indicated by the second access signal.

一种可能的实现方式，Δ大于或等于第一接入信号对应的第四频率位置与第一接入信号指示的控制资源集合对应的第五频率位置之间的频率间隔。其中，第四频率位置为第一接入信号的频域资源中，最低频的RB对应的频率位置。第五频率位置为控制资源集合中，最低频的RB对应的频率位置。In a possible implementation manner, Δ is greater than or equal to the frequency interval between the fourth frequency position corresponding to the first access signal and the fifth frequency position corresponding to the control resource set indicated by the first access signal. The fourth frequency position is the frequency position corresponding to the lowest frequency RB in the frequency domain resources of the first access signal. The fifth frequency position is the frequency position corresponding to the lowest frequency RB in the control resource set.

示例性的，以图9所示的第一接入信号和第一接入信号指示的控制资源集合为例。图9中，Δ为第一接入信号对应的第四频率位置与第一接入信号指示的控制资源集合对应的第五频率位置之间的频率间隔。Exemplarily, take the first access signal and the control resource set indicated by the first access signal as shown in FIG. 9 as an example. In FIG. 9 , Δ is the frequency interval between the fourth frequency position corresponding to the first access signal and the fifth frequency position corresponding to the control resource set indicated by the first access signal.

另一种可能的实现方式，Δ为第一频率位置中每个频率位置对应的第三接入信号中，每个第三接入信号的频率位置与每个第三接入信号指示的控制资源集合的频率位置之间的频率间隔中，最大的频率间隔。In another possible implementation manner, Δ is the frequency position of each third access signal in the third access signal corresponding to each frequency position in the first frequency position and the control resource indicated by each third access signal The largest frequency interval among the frequency intervals between the frequency positions of the set.

其中，任一个第三接入信号为假设网络设备在该第三接入信号对应的频率位置上发送的接入信号。Wherein, any third access signal is an access signal that is assumed to be sent by the network device at a frequency position corresponding to the third access signal.

示例性的，以第一频率位置包括3个频率位置，分别为频率位置1、频率位置2和频率位置3为例，若频率位置1与频率位置1对应的第三接入信号的指示的控制资源集合的频率位置之间的频率间隔为10080kHz，频率位置2与频率位置2对应的第三接入信号的指示的控制资源集合的频率位置之间的频率间隔为6840kHz，频率位置3 与频率位置3对应的第三接入信号的指示的控制资源集合的频率位置之间的频率间隔为2880kHz，则Δ为10080kHz。Exemplarily, taking the first frequency position including 3 frequency positions, which are respectively frequency position 1, frequency position 2 and frequency position 3, as an example, if frequency position 1 corresponds to the control of the indication of the third access signal corresponding to frequency position 1 The frequency interval between the frequency positions of the resource set is 10080 kHz, the frequency interval between the frequency positions of the frequency position 2 and the frequency positions of the control resource set indicated by the third access signal corresponding to the frequency position 2 is 6840 kHz, and the frequency position 3 and the frequency position The frequency interval between the frequency positions of the indicated control resource set of the third access signal corresponding to 3 is 2880 kHz, and Δ is 10080 kHz.
