Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communication technology, and in particular, to a communication method, apparatus, device and storage medium. BACKGROUND

[0002] In release (R) 18, the new radio (NR) technology is studied to support part of the dedicated spectrum of long term evolution (LTE) / global system for mobile communications-railway (GSM-R) for new radio (NR) technology. These spectrums mainly provide communication services for dedicated services such as power systems / railway systems, public inclusion and disaster relief in some areas.

[0003] These spectrums only support a subcarrier spacing of 15KHz, and the supported system bandwidth includes 5MHz and 3MHz. According to the provisions of the radio frequency (RF) channel bandwidth in NR and LTE, the number of available resource blocks (RBs) for 5MHz is 25. According to the provisions of the RF channel bandwidth in LTE, the number of available RBs for 3MHz is 15.

[0004] In the fifth generation wireless communication system (5G), the synchronization and physical broadcast channel block (SSB) includes a synchronization signal and a broadcast signal. The synchronization signal includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The broadcast signal includes physical broadcast channel (PBCH) data and PBCH demodulation reference signal (DMRS)

[0005] Since the bandwidth resource reserved for the NR system is not fixed, for example, between 2.8MHz and 3.6MHz. Most of the time, the reserved resource cannot carry a complete PBCH transmission. Then the physical resource actually used for PBCH transmission is also uncertain. Obviously, this uncertainty will bring additional complexity to the terminal demodulating PBCH. SUMMARY

[0107] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0108] The communication methods disclosed herein can be applied to Figure 1 The wireless communication system 100 shown may include network device 110 and terminal 120. It is understood that... Figure 1 The wireless communication system shown is for illustrative purposes only. A wireless communication system may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 1 Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0109] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ different communication technologies, such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency-Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), and Carrier Sense Multiple Access with Collision Avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G (Generation) networks, 3G networks, 4G networks, or future evolution networks, such as the 5th Generation Wireless Communication System (5G) network. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure sometimes refers to the wireless communication network simply as a network.

[0110] Furthermore, the network device 110 involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eNB), a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and receiving point (TRP), etc. It can also be a gNB in ​​an NR system, or a component or part of a base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device. It should be understood that the specific technology and specific device form used in the embodiments of this disclosure are not limited.

[0111] Furthermore, the terminal 120 involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0112] In this embodiment, network device 110 and terminal 120 can employ any feasible wireless communication technology to transmit data to each other. The transmission channel corresponding to network device 110 sending data or control information to terminal 120 is called the downlink channel (DL), and the transmission channel corresponding to terminal 120 sending data or control information to network device 110 is called the uplink channel (UL). It is understood that the network device involved in this embodiment can be a base station. Of course, the network device can also be any other possible network device, and the terminal can be any possible terminal; this disclosure does not limit the possibilities.

[0113] Release 18 investigated support for NR technology using dedicated spectrum for LTE / GSM-R. Examples include frequency bands n8, n26, n28, and n100. This spectrum primarily provides communication services for dedicated services such as power / railway systems, public transportation, and disaster relief in certain countries and regions.

[0114] These spectrums only support subcarrier spacing of 15kHz, and the supported system bandwidths include 5MHz and 3MHz. According to the RF channel bandwidth specifications in NR and LTE, the number of available RBs for 5MHz is 25. According to the LTE RF channel bandwidth specifications, the number of available RBs for 3MHz is 15.

[0115] In 5G, SSB includes synchronization signals and broadcast signals. Synchronization signals include PSS and SSS. Broadcast signals include PBCH data and PBCH DMRS. For example... Figure 2As shown, a time-frequency domain structure for an SSB is provided. It can be seen that an SSB occupies 4 orthogonal frequency division multiplexing (OFDM) symbols in the time domain and 20 RBs in the frequency domain. Assuming a subcarrier spacing of 15 kHz, the PBCH occupies approximately 3.6 MHz of bandwidth.

[0116] For example, in the n100 scenario, the NR system needs to coexist with the GSM-R system. The bandwidth allocated to the NR system can be between 2.8MHz and 3.6MHz.

[0117] For the terminal, it needs to demodulate the PSS / SSS first, and then demodulate the PBCH based on the PSS / SSS at the relative resource location. However, since the terminal does not yet have system bandwidth information after demodulating the PSS or SSS, it is unaware of the system bandwidth, i.e., how many physical resource blocks (PRBs) are in the PBCH. Therefore, the terminal is also unaware of how much physical resource is received for PBCH demodulation.

[0118] For example Figure 3 As shown, the bandwidth of one frequency band is 5.6MHz. Assuming the bandwidth allocated to GSM-R is 2MHz, then the bandwidth available for the PBCH can be 5.6MHz. For example... Figure 4 As shown, under the same frequency band, if the bandwidth allocated to GSM-R is 2.8MHz, then the bandwidth available for PBCH will also be 2.8MHz.

[0119] Clearly, the uncertainty of GSM-R bandwidth leads to a variable amount of bandwidth resources reserved for the NR system, which in turn results in uncertain PBCH resources. Furthermore, in most cases, the reserved resources are insufficient to support a complete PBCH transmission. Therefore, the actual physical resources used for PBCH transmission are also uncertain. This uncertainty introduces additional complexity to the terminal's PBCH demodulation.

[0120] Therefore, this disclosure provides a communication method, apparatus, device, and storage medium. By transmitting the PBCH using a first resource amount smaller than the complete PBCH resource, the complexity of PBCH demodulation at the terminal is reduced, thereby improving the transmission efficiency of the PBCH.

[0121] Figure 5 This is a flowchart illustrating a communication method according to an exemplary embodiment, such as... Figure 5 As shown, the method is executed by the terminal and may include the following steps:

[0122] In step S11, the PBCH is received based at least on the first resource quantity.

[0123] In one embodiment, the terminal may receive the PBCH based at least on a first resource quantity, wherein the first resource quantity is less than the resource quantity required to transmit the complete PBCH.

[0124] For example, the terminal receives the PBCH based on the first resource quantity and obtains the information transmitted on the PBCH.

[0125] It is understandable that the resource requirement for transmitting a complete PBCH is typically 3.6MHz. Therefore, the initial resource requirement is less than 3.6MHz. In some cases, the initial resource requirement can be the minimum resource requirement for transmitting the PBCH, such as 2.8MHz.

[0126] Of course, the first resource quantity can be any value between the resource quantity occupied by transmitting a complete PBCH and the minimum resource quantity occupied by transmitting a PBCH, and this disclosure does not limit it.

[0127] It should be understood that by determining a relatively small first resource quantity, this disclosure ensures that the PBCH transmitted at the transmission location corresponding to that first resource quantity can be completely demodulated by the terminal. This reduces the complexity of PBCH demodulation and improves transmission efficiency.

[0128] In some implementations, the following steps may be included before S11:

[0129] In step S12, the first resource quantity is determined.

[0130] In some embodiments, the terminal may first determine a first resource quantity. For example, it may be determined based on a pre-defined protocol or a preset rule; this disclosure does not limit this determination.

[0131] This disclosure utilizes a first resource amount smaller than the complete PBCH resource to transmit the PBCH, thereby reducing the complexity of PBCH demodulation at the terminal and improving the transmission efficiency of the PBCH.

[0132] In the communication method provided in this embodiment, the value of the first resource quantity is a preset value of the protocol, or the value of the first resource quantity is determined according to a preset rule.

[0133] In some embodiments, the first resource quantity may be a protocol preset value specified in the protocol.

[0134] In some embodiments, the first resource quantity can be determined according to a preset rule.

[0135] For example, the first resource quantity can be the minimum bandwidth available for an NR system within a specific frequency band. For instance, if the minimum bandwidth available for an NR system in a specific frequency band is 2.8MHz, then the first resource quantity can also be determined to be 2.8MHz.

[0136] This disclosure utilizes the minimum bandwidth available for NR systems in a specific frequency band to transmit the PBCH, ensuring that the terminal can perform good demodulation of the PBCH, reducing the complexity of PBCH demodulation by the terminal, and improving the transmission efficiency of the PBCH.

[0137] In the communication method provided in this embodiment, the information transmitted on the PBCH is obtained by rate matching based on a first resource quantity.

[0138] In some embodiments, the information transmitted on the PBCH may be obtained by rate matching based on a first resource quantity.

[0139] For example, the information transmitted on the PBCH can be encoded, such as using polar codes. Rate matching is performed according to the size of the first resource quantity to ensure that the information transmitted on the PBCH can be completely mapped to the resource locations determined based on the first resource quantity.

[0140] This disclosure uses rate matching based on the first resource quantity to obtain the information transmitted on the PBCH, so as to ensure that the terminal can obtain complete information by demodulating the PBCH, reduce the complexity of the terminal demodulating the PBCH, and improve the transmission efficiency of the PBCH.

[0141] In the communication method provided in this embodiment, the information transmitted on the PBCH is obtained by rate matching based on a second resource quantity, wherein the second resource quantity is the amount of resources occupied by transmitting the complete PBCH.

[0142] In some embodiments, the information transmitted on the PBCH may be obtained by rate matching based on a second resource quantity.

[0143] For example, the information transmitted on the PBCH can be encoded, such as using polar codes. Furthermore, rate matching is performed according to the size of the second resource quantity to ensure that the information transmitted on the PBCH can be completely mapped to the resource locations determined based on the second resource quantity.

[0144] This disclosure obtains the information transmitted on the PBCH by rate matching according to the second resource quantity, so as to reduce the complexity of the terminal demodulating the PBCH and improve the transmission efficiency of the PBCH.

[0145] In the communication method provided in the embodiments of this disclosure Figure 6 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 6As shown, the information transmitted on the PBCH includes first PBCH information. Receiving the PBCH in S11, at least based on the first resource quantity, may include the following steps:

[0146] In step S21, the first PBCH information is received within the first transmission location.

[0147] In some embodiments, the terminal may receive first PBCH information within a first transmission location. The first transmission location is a transmission location determined based on a first resource quantity.

[0148] For example, the first PBCH information is information on rate matching performed by the network device based on a first resource quantity. The network device maps this first PBCH information resource to a first transmission location and sends it to the terminal. The terminal can receive the first PBCH information within the first transmission location.

[0149] For example, the first PBCH information is information for rate matching by the network device based on the second resource quantity. The network device first maps the first PBCH information to a first transmission location and then sends it to the terminal. The terminal can receive the first PBCH information within the first transmission location. Of course, in this case, the first PBCH information received by the terminal can be considered as not being the complete PBCH information. The remaining information may be mapped and sent by the network device at other transmission locations, or it may be discarded; this disclosure does not limit this.

[0150] This disclosure transmits the PBCH at a first transmission location determined by a first resource quantity, which can reduce the complexity of PBCH demodulation at the terminal and improve the transmission efficiency of PBCH.

[0151] In the communication method provided in this embodiment, the first transmission position is determined based on the position of the synchronization signal and the first resource quantity.

[0152] In some embodiments, the first transmission location may be determined based on the location of the PSS / SSS and the first resource quantity.

[0153] For example, assuming the frequency position of the synchronization grid of PSS / SSS is k and the first resource quantity is 2.8MHz, then the first transmission position of PBCH can be determined as [k-1MHz, k+1.8MHz], or [k-1.8MHz, k+1MHz], etc.

[0154] It is understandable that the relative position of the first transmission position with the synchronization grid of the PSS / SSS is different under different synchronization grids.

[0155] This disclosure provides a method for determining the first transmission location so that the PBCH can be transmitted through the first transmission location, which can reduce the complexity of PBCH demodulation at the terminal and improve the transmission efficiency of PBCH.

[0156] In the communication method provided in the embodiments of this disclosure Figure 7 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 7 As shown, receiving the first PBCH information within the first transmission position in S21 may further include the following steps:

[0157] In step S31, the first PBCH information is received in a preset order within the first transmission position.

[0158] In some embodiments, the terminal may receive the first PBCH information in a preset order within a first transmission location. The preset order may be frequency domain first, then time domain.

[0159] It can be understood that the mapping method for the first PBCH information at the first transmission location is frequency domain first, then time domain. Therefore, when the terminal receives the first PBCH information, it also follows the mapping method of frequency domain first, then time domain, and receives the first PBCH information within the first transmission location. Figure 8 As shown, network devices can perform resource mapping at the first transmission location in the order of frequency domain first, then time domain, i.e. Figure 8 The arrow shown. For example, Figure 9 In another scenario, as shown, the network device can perform resource mapping at the first transmission location in the order of frequency domain first, then time domain, and then at the second transmission location in the same order. That is... Figure 9 The arrows shown in the first transmission position and the arrows shown in the second transmission position.

[0160] This disclosure provides a method for receiving PBCH at a first transmission position, which can reduce the complexity of PBCH demodulation at the terminal and improve PBCH transmission efficiency.

[0161] In the communication method provided in the embodiments of this disclosure Figure 10 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 10 As shown, the information transmitted on the PBCH is obtained by rate matching based on the first resource quantity. Receiving the PBCH in S11 may further include the following steps:

[0162] In step S41, in response to the fact that the amount of resources allocated to PBCH is greater than the first amount of resources, PBCH retransmission information is received according to the second transmission position.

[0163] In some embodiments, if the terminal already knows the amount of resources allocated to the PBCH, and the actual amount of resources allocated to the PBCH is greater than the first resource amount, the terminal can receive PBCH retransmission information based on a second transmission location. The second transmission location is determined based on a third resource amount. The third resource amount is the actual amount of resources allocated to the PBCH. The second transmission location is any transmission location determined based on the third resource amount other than the first transmission location. The PBCH retransmission information is repetition information of a portion of the first PBCH information.

[0164] refer to Figure 9 In this scenario, after the terminal has connected to the network, it already knows the actual amount of resources allocated to the PBCH, i.e., the third resource amount. However, since network devices perform rate matching based on the first resource amount, in... Figure 9 At the second transmission position, PBCH repeat transmission information sent by network devices can be received. In some cases, the PBCH repeat transmission information may also be a repetition of part of the first PBCH information. Of course, in other cases, the PBCH repeat transmission information may also be a repetition of all of the first PBCH information. This disclosure does not limit this.

[0165] It is understandable that the first transmission position and the second transmission position can together constitute the transmission position determined by the third resource quantity. For example, if the transmission position determined based on the third resource quantity is [k-1.2MHz, k+1.8MHz], and the first transmission position can be [k-1MHz, k+1.8MHz], then the second transmission position is [k-1.2MHz, k-1MHz].

[0166] In some embodiments, the terminal may receive PBCH retransmission information at the second transmission location after it has already accessed the network and obtained the bandwidth actually allocated to the PBCH, and still needs to obtain the SSB.

[0167] This disclosure provides a method for receiving PBCH retransmission information at a second transmission location, which can reduce the complexity of PBCH demodulation at the terminal, improve PBCH transmission efficiency, and enhance system robustness.

[0168] In the communication method provided in the embodiments of this disclosure Figure 11 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 11 As shown, the method may also include the following steps:

[0169] In step S51, in response to the information transmitted on the PBCH, rate matching is performed based on the second resource quantity. Before de-rate matching, the first PBCH information is padded with symbols or bits.

[0170] In some embodiments, the information transmitted on the PBCH is rate-matched based on a second resource amount. Before the terminal de-rate-matches the received first PBCH information, it needs to perform sign padding or bit padding on the first PBCH information. Of course, for the network device to perform resource mapping, it can perform resource mapping only at the first transmission location, without performing resource mapping at the second transmission location, and discard the remaining information that was not resource-mapped at the first transmission location. Alternatively, the network device can also perform resource mapping at the first transmission location and then perform resource mapping at the second transmission location. However, for the terminal, since the terminal is not yet aware of the actual resource amount allocated to the PBCH, it only receives the first PBCH information at the first transmission location and performs sign padding or bit padding on the first PBCH information.

[0171] The first PBCH information after symbol padding is equal to the number of symbols after rate matching based on the second resource amount. The first PBCH information after bit padding is equal to the number of bits after rate matching based on the second resource amount.

[0172] For example, if the information transmitted on the PBCH is rate-matched based on the second resource quantity, the terminal is unaware of the actual bandwidth allocated to the PBCH during initial access. Therefore, the terminal can receive the PBCH within the first transmission location. However, since the complete PBCH information is rate-matched based on the second resource quantity, the first PBCH information received by the terminal at the first transmission location is not complete; that is, the first PBCH information is only a partial PBCH. Before de-rate-matching the first PBCH information, the terminal needs to complete the first PBCH information, i.e., perform symbol padding or bit padding, so that the terminal can perform de-rate-matching based on the padded first PBCH information.

[0173] In some embodiments, it is understood that, in response to the information transmitted on the PBCH being rate-matched based on the first resource quantity, the terminal can directly demodulate the first PBCH information without performing symbol padding or bit padding on the first PBCH.

[0174] In this disclosure, when the information transmitted on the PBCH is obtained by rate matching based on the second resource quantity, the first PBCH information is padded with symbols or bits so that the terminal can correctly demodulate the first PBCH information, thereby reducing the complexity of the terminal demodulating the PBCH and improving the transmission efficiency of the PBCH.

[0175] In the communication method provided in the embodiments of this disclosure Figure 12 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 12As shown, the information transmitted on the PBCH is obtained by rate matching based on the second resource quantity, and the terminal has determined the resource quantity allocated to the PBCH (e.g., the terminal can determine the resource quantity allocated to the PBCH after accessing the network). The information transmitted on the PBCH also includes second PBCH information, which is at least a portion of the remaining information other than the first PBCH information in the information obtained by rate matching based on the second resource quantity. Receiving the PBCH in S11, at least based on the first resource quantity, may further include the following steps:

[0176] In step S61, in response to the fact that the amount of resources allocated to the PBCH is greater than the first amount of resources, the second PBCH information is received according to the second transmission position.

[0177] In some embodiments, the terminal can, knowing the amount of resources allocated to the PBCH, perform rate matching based on the second resource amount in response to information transmitted on the PBCH. The information transmitted on the PBCH may further include second PBCH information. The second PBCH information is at least a portion of the remaining information other than the first PBCH information in the information obtained by rate matching based on the second resource amount.

[0178] For network devices, refer to Figure 9 After rate matching based on the second resource quantity, resource mapping can be performed at the first transmission position. Then, the remaining unmapped information can be mapped at the second transmission position. For example, resource mapping can be performed in the order of frequency domain first, then time domain. Figure 9 The network device maps the first PBCH information to resources in the first transmission location and the second PBCH information to resources in the second transmission location.

[0179] For example, once the terminal has connected to the network, the actual bandwidth allocated to the PBCH can be determined, i.e., the amount of resources allocated to the PBCH. If the information transmitted on the PBCH is obtained through rate matching based on the second resource amount, it can be determined that the first PBCH information received by the terminal at the first transmission location is not a complete PBCH. The terminal also needs to attempt to receive the second PBCH information. It can be understood that the second PBCH information is at least a portion of the remaining information besides the first PBCH information obtained through rate matching based on the second resource amount.

[0180] In some embodiments, in response to the PBCH being allocated more resources than the first resource amount, the terminal can receive second PBCH information based on a second transmission location. The second transmission location is determined based on a third resource amount. The third resource amount is the resource amount allocated to the PBCH, i.e., the actual resource amount allocated to the PBCH. The second transmission location is any transmission location determined based on the third resource amount other than the first transmission location.

[0181] For example, when the third resource allocated to the PBCH is greater than the first resource, the terminal can determine the second transmission location based on the third resource. Figure 9 The second transmission position is defined as follows. It can be understood that the second transmission position and the first transmission position together constitute the transmission position determined based on the third resource quantity. For example, the transmission position determined based on the third resource quantity is [k-1.2MHz, k+1.8MHz], the first transmission position can be [k-1MHz, k+1.8MHz], and the second transmission position can be [k-1.2MHz, k-1MHz]. The terminal can then receive the second PBCH information based on the second transmission position. This PBCH information is at least a portion of the remaining information besides the first PBCH information.

[0182] Of course, it should be understood that the transmission position corresponding to the third resource quantity is less than or equal to the transmission position corresponding to the second resource quantity. That is, the third resource quantity is less than or equal to the second resource quantity. When the third resource quantity is the same as the second resource quantity, the transmission position corresponding to the third resource quantity is the same as the transmission position corresponding to the second resource quantity. When the third resource quantity is less than the second resource quantity, the transmission position corresponding to the third resource quantity is also less than the same as the transmission position corresponding to the second resource quantity.

[0183] This disclosure allows the terminal to receive second PBCH information at a second transmission location, enabling the terminal to receive a more complete PBCH, reducing the complexity of PBCH demodulation, and improving PBCH transmission efficiency and accuracy.

[0184] In the communication method provided in the embodiments of this disclosure Figure 13 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 13 As shown, receiving the PBCH based at least on the first resource quantity in S11 may further include the following steps:

[0185] In step S71, the first PBCH information is received in a preset order within the first transmission position.

[0186] In some embodiments, the terminal may receive the first PBCH information at the first transmission location in the order of frequency domain first and then time domain.

[0187] In step S72, the second PBCH information is received in a preset order within the second transmission position.

[0188] In some embodiments, the terminal may receive the second PBCH information at the second transmission location in the order of frequency domain first and then time domain.

[0189] refer to Figure 9As shown, when transmitting the PBCH, the network device first performs resource mapping on the first PBCH information in the order of frequency domain first, then time domain at the first transmission location, and then performs resource mapping on the second PBCH information in the same order at the second transmission location. Therefore, for the terminal, it is also possible to receive the first PBCH information in the order of frequency domain first, then time domain at the first transmission location, and then receive the second PBCH information in the same order at the second transmission location.

[0190] This disclosure provides a method for receiving PBCH at different transmission locations, which can reduce the complexity of PBCH demodulation at the terminal and improve PBCH transmission efficiency.

[0191] In the communication method provided in the embodiments of this disclosure Figure 14 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 14 As shown, the method may also include the following steps:

[0192] In step S81, the first PBCH information and the second PBCH information are merged.

[0193] In some embodiments, the terminal may merge the received first PBCH information and the second PBCH information.

[0194] In step S81, before de-rate matching, the merged information is padded with symbols or bits.

[0195] In some embodiments, before performing rate matching on the merged information, the terminal may perform symbol padding or bit padding on the merged information. Specifically, the information after symbol padding is equal to the number of symbols after rate matching based on the second resource quantity, and the information after bit padding is equal to the number of bits after rate matching based on the second resource quantity.

[0196] It's understandable that the information transmitted on the PBCH is rate-matched based on the second resource amount. However, if the actual allocated third resource amount for the PBCH is less than the second resource amount, the combined first and second PBCH information received by the terminal will be incomplete. Therefore, symbol padding or bit padding is required before rate matching can be de-matched.

[0197] In some embodiments, if the second transmission location receives PBCH retransmission information instead of second PBCH information, the terminal can merge the first PBCH information and the PBCH retransmission information, but there is no need to pad the merged information with symbols or bits. Of course, symbol padding or bit padding can also be performed on the merged information of the first PBCH information and the PBCH retransmission information, and this disclosure does not limit this.

[0198] In this disclosure, when the information transmitted on the PBCH is obtained by rate matching based on the second resource quantity, the first PBCH information and the second PBCH information are merged and then padded with symbols or bits so that the terminal can correctly demodulate the PBCH, reduce the complexity of the terminal demodulating the PBCH, and improve the transmission efficiency of the PBCH.

[0199] In the communication method provided in the embodiments of this disclosure Figure 15 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 15 As shown, the information transmitted on the PBCH is obtained by rate matching based on the second resource quantity, and the method may further include the following steps:

[0200] In step S91, the third transmission location is determined based on the second resource quantity.

[0201] In some embodiments, the terminal may determine the third transmission location based on the second resource quantity.

[0202] For example, the terminal can determine the third transmission position based on the location of the PSS / SSS and the second resource quantity. Assuming the frequency position of the PSS / SSS synchronization grid is k, then the third transmission position of the PBCH can be determined as [k-1.8MHz, k+1.8MHz]. It can be understood that the relative position of the third transmission position to the PSS / SSS synchronization grid differs under different synchronization grids.

[0203] S11 may include receiving information transmitted on the PBCH based at least on the first resource quantity, which may include the following steps:

[0204] In step S92, the information transmitted on the PBCH is processed in a preset order within the third transmission position.

[0205] In some embodiments, the terminal may process the information transmitted on the PBCH in the third transmission location in the order of frequency domain first and time domain second.

[0206] For example Figure 16As shown, network devices also perform resource mapping directly based on the complete PBCH resources. That is, after the network device performs rate matching on the PBCH information to be transmitted based on the second resource quantity, it can perform resource mapping at the third transmission location in the order of frequency domain first, then time domain. At this point, only the resources actually allocated to the PBCH are successfully mapped. Figure 16 The first and second transmission positions are defined in the PBCH. The remaining positions, not allocated to the PBCH, are considered as having failed resource mapping and are discarded. For the terminal, it can also process information transmitted on the PBCH based on the third transmission position. That is, the terminal can directly receive information based on the full bandwidth of the PBCH.

[0207] This disclosure enables the reception of PBCH at a third transmission location, reducing the complexity of PBCH demodulation at the terminal and improving PBCH transmission efficiency.

[0208] In the communication method provided in the embodiments of this disclosure Figure 17 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 17 As shown, in S92, processing the information transmitted on the PBCH in a preset order within the third transmission position may further include the following steps:

[0209] In step S101, the first PBCH information is received within the first transmission location.

[0210] In some embodiments, when a terminal first accesses the network, it is unaware of the actual amount of resources allocated to the PBCH, and therefore the terminal has not yet determined the second transmission location. The terminal can receive the first PBCH information within the first transmission location.

[0211] For example, when a terminal first accesses the network, it can determine the first transmission location, but at this time, since it does not yet know the actual bandwidth allocated to the PBCH, it cannot determine the second transmission location.

[0212] In step S102, symbol stuffing or bit stuffing is performed at positions other than the first transmission position in a preset order.

[0213] In some embodiments, reference Figure 16 Because network devices perform resource mapping based on the complete PBCH resource, the information actually mapped at the first transmission location may be a portion of the complete PBCH information.

[0214] For example, suppose the complete PBCH information consists of bits 1 to 100. Resource mapping at the first transmission location might involve bits 16 to 85. Therefore, when the terminal receives information transmitted on the PBCH at the third transmission location, it will simultaneously pad bits 1 to 15 and receive the first PBCH information, i.e., bits 16 to 85. Then it will pad bits 86 to 100.

[0215] It is understood that the sign padding or bit padding in the aforementioned embodiments differs from the sign stuffing or bit stuffing in the previous embodiments. Since the network device in the aforementioned embodiments first performs resource mapping on the first transmission position, the first PBCH information and the second PBCH information can be the first N bits of the complete PBCH information. For example, taking the complete PBCH information as including bits 1 to 100 as an example, in the aforementioned embodiments, the network device transmits bits 1 to 70 at the first transmission position and bits 71 to 90 at the second transmission position. Therefore, after the terminal receives the data sequentially, it only needs to pad the data that was subsequently discarded. For example, padding bits 91 to 100 is sufficient.

[0216] This disclosure enables the reception of PBCH at the first transmission position, reducing the complexity of PBCH demodulation at the terminal and improving PBCH transmission efficiency.

[0217] In the communication method provided in the embodiments of this disclosure Figure 18 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 18 As shown, in S92, processing the information transmitted on the PBCH in a preset order within the third transmission position may include the following steps:

[0218] In step S111, the first PBCH information is received within the first transmission location.

[0219] In some embodiments, the terminal may receive the first PBCH information in the order of frequency domain first and then time domain within the first transmission location.

[0220] In step S112, the second PBCH information is received within the second transmission location.

[0221] In some embodiments, the terminal may receive the second PBCH information in the second transmission location in the order of frequency domain first and time domain second.

[0222] It is understandable that after the terminal has accessed the network, since the actual bandwidth allocated to the PBCH has been determined, it can receive the first PBCH information at the first transmission location and also receive the second PBCH information at the second transmission location.

[0223] In step S113, symbol stuffing or bit stuffing is performed in a preset order at positions other than the first transmission position and the second transmission position.

[0224] In some embodiments, the terminal may perform symbol stuffing or bit stuffing in the order of frequency domain first and then time domain at locations other than the first transmission location and the second transmission location.

[0225] refer to Figure 16 Once the terminal has connected to the network, it already knows the resources actually allocated to the PBCH. Therefore, during reception, it can perform symbol stuffing or bit stuffing simultaneously with receiving the first and second PBCH information.

[0226] Taking a complete PBCH message consisting of 1 to 100 bits as an example, the terminal can first fill in 1 to 5 bits, and then receive 6 to 15 bits at the second transmission position. Then it can receive 16 to 85 bits at the first transmission position, and then receive 86 to 95 bits at the second transmission position. Finally, it can fill in 96 to 100 bits.

[0227] In step S114, the first PBCH information, the second PBCH information, and the padded symbols or bits are merged.

[0228] In some embodiments, the terminal can combine the first PBCH information received in S111, the second PBCH information received in S112, and the symbols or bits obtained by padding in S113, so as to perform rate matching on the combined information.

[0229] This disclosure enables PBCH to be received at both the first and second transmission positions, reducing the complexity of PBCH demodulation at the terminal and improving PBCH transmission efficiency.

[0230] Based on the same concept, this disclosure also provides a communication method performed on the network device side.

[0231] Figure 19 This is a flowchart illustrating yet another communication method according to an exemplary embodiment, such as... Figure 19 As shown, the method is executed by a network device and may include the following steps:

[0232] In step S121, resource mapping is performed on the information transmitted on the PBCH.

[0233] In some embodiments, network devices can perform resource mapping on information that needs to be transmitted on the PBCH.

[0234] In step S122, PBCH is sent.

[0235] In one embodiment, the network device may send the PBCH mapped in S121. The PBCH sent by the network device may include at least a PBCH sent based on a first resource amount. The first resource amount is less than the resource amount required to transmit the complete PBCH.

[0236] A PBCH sent based on the first resource quantity can be a PBCH after resource mapping based on the first resource quantity.

[0237] It is understandable that the resource requirement for transmitting a complete PBCH is typically 3.6MHz. Therefore, the initial resource requirement is less than 3.6MHz. In some cases, the initial resource requirement can be the minimum resource requirement for transmitting the PBCH, such as 2.8MHz.

[0238] Of course, the first resource quantity can be any value between the resource quantity occupied by transmitting a complete PBCH and the minimum resource quantity occupied by transmitting a PBCH, and this disclosure does not limit it.

[0239] It should be understood that by determining a relatively small first resource quantity, this disclosure ensures that the PBCH transmitted at the transmission location corresponding to that first resource quantity can be completely demodulated by the terminal. This reduces the complexity of PBCH demodulation and improves transmission efficiency.

[0240] In some implementations, the following steps may be included before S121:

[0241] In step S123, the first resource quantity is determined.

[0242] In some embodiments, the network device may first determine a first resource quantity. For example, it may be determined based on a pre-defined protocol or a preset rule; this disclosure does not limit this determination.

[0243] This disclosure utilizes a first resource amount smaller than the complete PBCH resource to transmit the PBCH, thereby reducing the complexity of PBCH demodulation at the terminal and improving the transmission efficiency of the PBCH.

[0244] In the communication method provided in this embodiment, the value of the first resource quantity is a preset value of the protocol, or the value of the first resource quantity is determined according to a preset rule.

[0245] In some embodiments, the first resource quantity may be a protocol preset value specified in the protocol.

[0246] In some embodiments, the first resource quantity can be determined according to a preset rule.

[0247] For example, the first resource quantity can be the minimum bandwidth available for an NR system within a specific frequency band. For instance, if the minimum bandwidth available for an NR system in a specific frequency band is 2.8MHz, then the first resource quantity can also be determined to be 2.8MHz.

[0248] This disclosure utilizes the minimum bandwidth available for NR systems in a specific frequency band to transmit the PBCH, ensuring that the terminal can perform good demodulation of the PBCH, reducing the complexity of PBCH demodulation by the terminal, and improving the transmission efficiency of the PBCH.

[0249] In the communication method provided in the embodiments of this disclosure Figure 20 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 20 As shown, the method may also include the following steps:

[0250] In step S131, rate matching is performed based on the first resource quantity to obtain the information transmitted on the PBCH.

[0251] In some embodiments, the network device may perform rate matching based on a first resource quantity to obtain the information transmitted on the PBCH.

[0252] For example, the information to be transmitted on the PBCH can be encoded, such as using polar codes. Rate matching is then performed according to the size of the first resource quantity to ensure that the information transmitted on the PBCH can be completely mapped to the resource locations determined based on the first resource quantity.

[0253] This disclosure uses rate matching based on the first resource quantity to obtain the information transmitted on the PBCH, so as to ensure that the terminal can obtain complete information by demodulating the PBCH, reduce the complexity of the terminal demodulating the PBCH, and improve the transmission efficiency of the PBCH.

[0254] In the communication method provided in the embodiments of this disclosure Figure 21 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 21 As shown, the method may also include the following steps:

[0255] In step S141, rate matching is performed based on the second resource quantity to obtain the information transmitted on the PBCH.

[0256] In some embodiments, the network device can perform rate matching based on a second resource quantity to obtain the information transmitted on the PBCH. The second resource quantity is the amount of resources required to transmit a complete PBCH.

[0257] For example, the information transmitted on the PBCH can be encoded, such as using polar codes. Rate matching is performed according to the size of the second resource quantity to ensure that the information transmitted on the PBCH can be completely mapped to the resource locations determined based on the second resource quantity.

[0258] This disclosure obtains the information transmitted on the PBCH by rate matching according to the second resource quantity, so as to reduce the complexity of the terminal demodulating the PBCH and improve the transmission efficiency of the PBCH.

[0259] In the communication method provided in the embodiments of this disclosure Figure 22 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 22 As shown, the information transmitted on the PBCH includes the first PBCH information. Sending the PBCH in S122 may include the following steps:

[0260] In step S151, the first transmission location is determined based on the first resource quantity.

[0261] In some embodiments, the network device may determine the first transmission location based on a first resource quantity.

[0262] In step S152, the first PBCH information is sent within the first transmission location.

[0263] In some embodiments, the network device may send first PBCH information within a first transmission location.

[0264] For example, the first PBCH information is rate-matched based on the first resource quantity, and the first PBCH information resource is mapped to the first transmission location for transmission.

[0265] For example, the first PBCH information is rate-matched based on the second resource quantity, and the first PBCH information resource is mapped to the first transmission location for transmission.

[0266] You can refer to this. Figure 8 As shown, of course, if the first PBCH information is rate-matched based on the second resource quantity, the remaining information that has not been resource-mapped at the first transmission location can be resource-mapped at other transmission locations or discarded, and this disclosure does not limit it.

[0267] This disclosure transmits the PBCH at a first transmission location determined by a first resource quantity, which can reduce the complexity of PBCH demodulation at the terminal and improve the transmission efficiency of PBCH.

[0268] In the communication method provided in the embodiments of this disclosure Figure 23 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 23As shown, determining the first transmission location based on the first resource quantity in S151 may further include the following steps:

[0269] In step S161, the first transmission position is determined based on the position of the synchronization signal and the first resource quantity.

[0270] In some embodiments, the network device may determine the first transmission location based on the location of the PSS / SSS and the first resource quantity.

[0271] For example, assuming the frequency position of the synchronization grid of PSS / SSS is k and the first resource quantity is 2.8MHz, then the first transmission position of PBCH can be determined as [k-1MHz, k+1.8MHz], or [k-1.8MHz, k+1MHz], etc.

[0272] It is understandable that the relative position of the first transmission position with the synchronization grid of the PSS / SSS is different under different synchronization grids.

[0273] This disclosure provides a method for determining the first transmission location so that the PBCH can be transmitted through the first transmission location, which can reduce the complexity of PBCH demodulation at the terminal and improve the transmission efficiency of PBCH.

[0274] In the communication method provided in the embodiments of this disclosure Figure 24 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 24 As shown, S121, which maps resources for information transmitted on the Physical Broadcast Channel (PBCH), may also include the following steps:

[0275] In step S171, the first PBCH information is mapped to resources in a preset order within the first transmission location.

[0276] In some embodiments, the network device may perform resource mapping on the first PBCH information in a preset order within a first transmission location. The preset order may be a frequency domain-first, then time domain-first, order.

[0277] For example, resource mapping in the time domain can occupy 4 OFDM symbols.

[0278] like Figure 8 As shown, network devices can perform resource mapping at the first transmission location in the order of frequency domain first, then time domain, i.e. Figure 8 The arrow shown.

[0279] This disclosure provides a method for transmitting PBCH at the first transmission position, which can reduce the complexity of PBCH demodulation at the terminal and improve PBCH transmission efficiency.

[0280] In the communication method provided in the embodiments of this disclosure Figure 25 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 25 As shown, the information transmitted on the PBCH is obtained by rate matching based on the first resource quantity. Sending the PBCH in S122 may further include the following steps:

[0281] In step S181, in response to the fact that the amount of resources allocated to PBCH is greater than the amount of the first resource, the second transmission location is determined based on the third resource.

[0282] In some embodiments, in response to a situation where the amount of resources actually allocated to the PBCH is greater than the first amount of resources, the network device may determine the second transmission location based on the third amount of resources.

[0283] The second transmission location is the transmission location other than the first transmission location among the transmission locations determined based on the third resource quantity, and the third resource quantity is the actual resource quantity allocated to the PBCH.

[0284] In step S182, PBCH repeat transmission information is sent according to the second transmission position.

[0285] In some embodiments, the network device may send PBCH repeat transmission information based on the second transmission location.

[0286] refer to Figure 9 In this process, since the network device performs rate matching based on the first resource quantity, it can send PBCH retransmission information at the second transmission location. In some cases, the PBCH retransmission information is a repetition of part of the first PBCH information. Of course, in some cases, the PBCH retransmission information can also be a repetition of all the first PBCH information. This disclosure does not limit this.

[0287] It is understandable that the first transmission position and the second transmission position can together constitute the transmission position determined by the third resource quantity. For example, if the transmission position determined based on the third resource quantity is [k-1.2MHz, k+1.8MHz], and the first transmission position can be [k-1MHz, k+1.8MHz], then the second transmission position is [k-1.2MHz, k-1MHz].

[0288] This disclosure provides a method for receiving PBCH retransmission information at a second transmission location, which can reduce the complexity of PBCH demodulation at the terminal, improve PBCH transmission efficiency, and enhance system robustness.

[0289] In the communication method provided in the embodiments of this disclosure Figure 26 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 26As shown, the method may also include the following steps:

[0290] In step S191, in response to the information transmitted on the PBCH, rate matching is performed based on the second resource quantity, and information in the information transmitted on the PBCH that has not been resource-mapped at the first transmission position is discarded.

[0291] In some embodiments, the information transmitted on the PBCH is obtained through rate matching based on a second resource quantity. After performing resource mapping at the first transmission location, the network device can discard any remaining unmapped information.

[0292] For example, although network devices perform rate matching based on the second resource quantity, they only map a portion of the PBCH information (i.e., the first PBCH information) at the first transmission location. The remaining information can be mapped at other transmission locations. Of course, it is also possible to choose to discard it directly.

[0293] In this disclosure, when the information transmitted on the PBCH is obtained by rate matching based on the second resource quantity, some information that has not been mapped to resources is discarded, thereby reducing the complexity of the terminal demodulating the PBCH and improving the transmission efficiency of the PBCH.

[0294] In the communication method provided in the embodiments of this disclosure Figure 27 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 27 As shown, the information transmitted on the PBCH is obtained by rate matching based on the second resource quantity. The information transmitted on the PBCH also includes second PBCH information, which is at least a portion of the remaining information in the information obtained by rate matching based on the second resource quantity, excluding the first PBCH information. Sending the PBCH in S121 may further include the following steps:

[0295] In step S201, in response to the fact that the amount of resources allocated to PBCH is greater than the first amount of resources, the second transmission position is determined based on the third amount of resources.

[0296] In some embodiments, in response to the PBCH being allocated more resources than a first resource, the network device may determine a second transmission location based on a third resource.

[0297] It can be understood that the second transmission position and the first transmission position together constitute the transmission position determined based on the third resource quantity. For example, the transmission position determined based on the third resource quantity is [k-1.2MHz, k+1.8MHz], the first transmission position can be [k-1MHz, k+1.8MHz], and the second transmission position can be [k-1.2MHz, k-1MHz]. The terminal can then receive the second PBCH information according to the second transmission position. This PBCH information is at least a portion of the remaining information other than the first PBCH information.

[0298] In step S202, the second PBCH information is sent at the second transmission location.

[0299] In some embodiments, the network device may send second PBCH information based on a second transmission location.

[0300] The second PBCH information is at least a portion of the remaining information other than the first PBCH information obtained from rate matching based on the second resource quantity.

[0301] For example, you can refer to Figure 9 As shown, when performing resource mapping, the network device can first map the first PBCH information at the first transmission location in the order of frequency domain first, then time domain, and then map the remaining second PBCH information at the second transmission location in the same order. Of course, if there is still unmapped information, the network device can choose to discard it.

[0302] This disclosure allows the terminal to send a second PBCH information at a second transmission location, enabling the terminal to receive a more complete PBCH, reducing the complexity of PBCH demodulation, and improving the transmission efficiency and accuracy of PBCH.

[0303] In the communication method provided in the embodiments of this disclosure Figure 28 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 28 As shown, the resource mapping of information transmitted on the physical broadcast channel PBCH in S121 may also include the following steps:

[0304] In step S211, the first PBCH information is resource-mapped in a preset order within the first transmission location.

[0305] In some embodiments, the terminal may perform resource mapping on the first PBCH information at the first transmission location, in the order of frequency domain first and then time domain.

[0306] In step S212, the second PBCH information is resource-mapped in a preset order within the second transmission location.

[0307] In some embodiments, the terminal may perform resource mapping on the second PBCH information at the second transmission location, in the order of frequency domain first and then time domain.

[0308] It is understood that in some embodiments, such as Figure 9 As shown, the network device can first perform resource mapping on the first PBCH information at the first transmission location, and then perform resource mapping on the second PBCH information at the second transmission location.

[0309] For example, the first PBCH information and / or the second PBCH information can be rate-matched information.

[0310] This disclosure provides a method for transmitting PBCH at different transmission locations, which can reduce the complexity of PBCH demodulation at the terminal and improve PBCH transmission efficiency.

[0311] In the communication method provided in the embodiments of this disclosure Figure 29 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 29 As shown, the method may also include the following steps:

[0312] In step S221, in response to the information transmitted on the PBCH, rate matching is performed based on the second resource quantity, and information in the information transmitted on the PBCH that is not mapped to resources in the first transmission position and the second transmission position is discarded.

[0313] In some embodiments, the information transmitted on the PBCH is obtained by rate matching based on a second resource quantity, referring to... Figure 9 When performing resource mapping, network devices can first perform resource mapping at the first transmission location. Then, the remaining unmapped information is mapped at the second transmission location. After that, if there is still any unmapped information, it is discarded.

[0314] This disclosure can discard some information that has not been mapped to resources so that the terminal can correctly demodulate the PBCH, reduce the complexity of the terminal demodulating the PBCH, and improve the transmission efficiency of the PBCH.

[0315] In the communication method provided in the embodiments of this disclosure Figure 30 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 30 As shown, the information transmitted on the PBCH is obtained by rate matching based on the second resource quantity, and the method may further include the following steps:

[0316] In step S231, the third transmission location is determined based on the second resource quantity.

[0317] In some embodiments, the network device may determine the third transmission location based on the second resource quantity.

[0318] For example, network devices can determine the third transmission location based on the location of the PSS / SSS and the second resource quantity. Assuming the frequency position of the PSS / SSS synchronization grid is k, then the third transmission location of the PBCH can be determined as [k-1.8MHz, k+1.8MHz]. It can be understood that the relative position of the third transmission location to the PSS / SSS synchronization grid differs under different synchronization grids.

[0319] S121, which involves resource mapping of information transmitted on the Physical Broadcast Channel (PBCH), may also include:

[0320] In step S232, resource mapping is performed on the information transmitted on the PBCH in a preset order within the third transmission location.

[0321] In some embodiments, the network device may perform resource mapping on the information transmitted on the PBCH in the third transmission location, in the order of frequency domain first and time domain second.

[0322] like Figure 16 As shown, network devices can perform resource mapping on the PBCH resources to be transmitted. For example, resource mapping can be performed in the order of frequency domain first and then time domain.

[0323] This disclosure allows for resource mapping of information transmitted on the PBCH at a third transmission location, reducing the complexity of PBCH demodulation at the terminal and improving PBCH transmission efficiency.

[0324] In the communication method provided in the embodiments of this disclosure Figure 31 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 31 As shown, the method may also include the following steps:

[0325] In step S241, information that performs resource mapping at locations other than the first and second transmission locations in the information transmitted on the PBCH is discarded.

[0326] In some embodiments, the network device performs resource mapping at a third transmission location. This third transmission location includes both the first and second transmission locations. The network device may discard information related to resource mapping performed at locations other than the first and second transmission locations.

[0327] refer to Figure 16In network devices, resource mapping is performed on complete PBCH resources, but the actual allocated resources for a PBCH may not be the complete PBCH resource. Therefore, during resource mapping, some PBCH information may be mapped onto resources that have not been allocated. This portion of information cannot be successfully mapped because the resources have not been allocated. The network device can discard this portion of information.

[0328] This disclosure can discard part of the PBCH, reduce the complexity of PBCH demodulation at the terminal, and improve the transmission efficiency of PBCH.

Figure 32 The device 200 includes a receiving module 201, configured to receive a physical broadcast channel PBCH based at least on a first resource quantity, wherein the first resource quantity is less than the resource quantity required to transmit a complete PBCH.

[0333] This disclosure utilizes a first resource amount smaller than the complete PBCH resource to transmit the PBCH, thereby reducing the complexity of PBCH demodulation at the terminal and improving the transmission efficiency of the PBCH.

[0334] In some implementations, the value of the first resource quantity is a protocol preset value, or the value of the first resource quantity is determined according to preset rules.
