Description

Access method, device and storage medium of machine type communication system

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an access method, an access device, and a storage medium for a machine-type communication system.

Background

Machine Type Communication (MTC) refers to Communication between machines without human interference, and is widely used in various fields such as smart cities (e.g., meter reading), smart agriculture (e.g., collection of information such as temperature and humidity), smart transportation (e.g., sharing a single vehicle/sharing a vehicle), and the like. At present, a basic MTC communication framework is formed in a Long Term Evolution (LTE) system (mainly release 12-release 13), and the characteristics of low complexity, low manufacturing cost, coverage enhancement, power saving and the like can be supported. The conventional MTC system is deployed in the spectrum of the LTE system, and users of the conventional LTE system share frequency resources and partial channels. Specifically, the conventional MTC system and LTE system users share a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH).

At present, for a conventional LTE system, when a User Equipment (UE) wants to access a certain cell, the UE first receives a PSS and an SSS for downlink synchronization, and after the downlink synchronization is completed, the User continues to receive and demodulate a PBCH, which is mainly to receive a Master Information Block (MIB). When PBCH is successfully received and demodulated, the Information of the subsequent corresponding System Information Block (System Information Block) is continuously received, and the relevant parameters for subsequent random access are read. Since the conventional MTC system shares the PSS, SSS, and PBCH of the LTE system, for the user equipment of the LTE system, when the MTC system is accessed, after successfully receiving and demodulating the PBCH, the user equipment will continue to receive the SIB and subsequent actions to access the LTE system.

However, considering the lack of flexibility in the manner in which MTC systems need to be deployed based on LTE systems, the industry has begun to consider independent deployment of MTC systems, such as allocating independent spectrum, dedicated channels/signals, and independently transmitting PSS/SSS and PBCH. However, for the users of the conventional LTE system, the SIB reception operation continues after the PBCH is successfully received and demodulated, and actually, the independently deployed MTC system does not have the subsequent SIB transmission, so the users of the conventional LTE system may perform multiple attempts for reception and eventually fail, which causes unnecessary power consumption.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Before introducing the access method of the machine type communication system provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The application scenario may include an MTC system, which may be deployed based on other communication systems, for example, based on an LTE system deployment (or referred to as LTE in-band deployment, i.e., deployment within a spectrum of the LTE system), may also be based on a subsequent further evolved communication system (e.g., a 5G communication system), or may also be deployed independently. In various embodiments of the present disclosure, an LTE system is taken as an example, that is, the MTC system may be deployed based on the LTE system or deployed independently.

Taking a conventional LTE system as an example, when a user equipment needs to access the LTE system (i.e. wants to access a cell), the user equipment needs to receive PSS and SSS signals for downlink synchronization. In the LTE system, whether a Frequency Division Duplex (FDD) LTE system or a Time Division Duplex (TDD) LTE system, the structures of the PSS and SSS signals are the same, but the Time domain positions are different in the frame. Wherein, for FDD LTE, PSS is sent in the last symbol (symbol) of the first slot (slot) of subframes 0 and 5; the SSS is also transmitted in the same slot of subframes 0 and 5 as the PSS, but the SSS is located in the second last symbol, one symbol ahead of the PSS, where a symbol refers to an Orthogonal Frequency Division Multiplexing (OFDM) symbol. For TDD LTE, PSS is sent in the third symbol of subframes 1 and 6 (i.e. DwPTS, downlink pilot timeslot); while SSS is sent in the last symbol of subframes 0 and 5, three symbols ahead of PSS.

The user equipment does not know the size of the system bandwidth when it is powered on, but knows the frequency band and bandwidth supported by itself. In order to enable the user equipment to detect the frequency and symbol synchronization information of the system as soon as possible, regardless of the system bandwidth size, the PSS and the SSS are located on the central 72 subcarriers, not containing Direct Current (DC) subcarriers. The user equipment may attempt to receive the PSS and SSS near the center frequency point of the LTE frequencies it supports. After receiving the PSS and the SSS, information such as a Physical-layer Cell Identity (PCI), a location of a subframe 0 in a system frame, whether the Cell operates in an FDD or TDD mode, and the like can be obtained, so that downlink synchronization can be performed according to the information.

After the downlink synchronization is completed, the user equipment continues to receive and demodulate the PBCH. The PBCH is used for a Master Information Block (MIB) of a transmission system, and the MIB contains 24-bit (bit) Information, and includes: a downlink system bandwidth (3bit) of a cell, a Physical Hybrid ARQ Indicator Channel (PHICH) configuration (3bit), system time information (e.g., system frame number) (8bit), subsequent system message scheduling information (5bit), and a reserved bit (5bit) of a plurality of bits.

Here, the PBCH is located in the first 4 symbols of the 2 nd slot of subframe 0 in the time domain, and occupies 72 central subcarriers (without DC subcarrier) in the frequency domain. In the LTE system, the PBCH is repeatedly transmitted 4 times in a period with a duration of 40ms, i.e. 40ms is a period, the MIB is transmitted once every period, and in a period, the last three times are repeated, and the MIB content is the same as that of the first transmission. It should be noted that the received MIB carries a System Frame Number (SFN) that is 8 bits higher, while the complete SFN is 10 bits, and the remaining 2 bits need to be obtained by blind detection of PBCH. Each transmission of 4 repeated transmissions in one period of the PBCH carries the same decoding information (coded bits), that is, each transmission can be independently decoded, so that under the condition that the channel quality is good enough, the user equipment can only receive one of the 40ms signals, and can successfully decode the remaining 2 bits; if not, the PBCH is soft combined with the content of the next transmission and then decoded until the PBCH is successfully decoded, thereby completing the reception and demodulation of the PBCH.

In the MTC system, in addition to the PBCH transmission procedure, additional PBCH repetition transmission is required. That is, in addition to transmitting PBCH in the first 4 symbols of the 2 nd slot of subframe 0, the PBCH needs to be repeatedly transmitted on the remaining physical resources of subframe 9 and subframe 0. For LTE systems, PBCH reception and demodulation may therefore be performed by combining the first 4 symbols of the 2 nd slot of subframe 0 at 40 ms. For MTC systems, all resources of subframe 9 and subframe 0 may be combined for PBCH reception and demodulation.

Although independent spectrum, dedicated channels and signals, and independent PSS, SSS and PBCH are configured for the independently deployed MTC system, the above method is adopted for the reception of PSS, SSS and PBCH of the independently deployed MTC system. Therefore, no matter whether the MTC system is deployed based on the LTE system or deployed independently, when a certain ue needs to access the MTC system or the LTE system, the ue needs to first receive PSS and SSS signals for downlink synchronization, and receive and demodulate the PBCH after the downlink synchronization. Based on the above application scenarios, the following describes an access method of the machine type communication system provided by the present disclosure.

Fig. 1 is a flowchart illustrating an access method of a machine type communication system according to an exemplary embodiment, and the method, as shown in fig. 1, for a user equipment of a first communication system may include the following steps.

In step S11, in the process of accessing the MTC system, after receiving the MIB, obtaining deployment mode information in the MIB, where the deployment mode information is used to indicate that the MTC system is deployed independently or based on the first communication system.

In step S12, when the deployment mode information indicates that the MTC system is deployed independently, the designated action is abandoned, and the designated action includes an action that needs to be executed after receiving the MIB in the access procedure of the first communication system.

In various embodiments of the present disclosure, the first communication system may be an LTE system supporting an MTC system, or may be a next generation communication system that is further evolved in the following, for example, a 5G communication system. In this embodiment, the LTE system is taken as an example. The MTC system may be deployed independently, provided with a dedicated frequency spectrum, dedicated channels and signals, and independent PSS, SSS, and PBCH; the multiplexing of PSS, SSS and PBCH in the LTE system may also be based on LTE system deployment, i.e. deployment within the spectrum of the LTE system.

Although, no matter whether the MTC system is deployed based on the LTE system or deployed independently, when a certain ue needs to access the MTC system or the LTE system, the ue needs to first receive PSS and SSS signals for downlink synchronization, and then receive and demodulate the PBCH after the downlink synchronization. However, if the MTC system is deployed independently, when accessing the MTC system, for a ue of the LTE system, after receiving PSS and SSS signals for downlink synchronization and receiving and demodulating PBCH after downlink synchronization, the ue continues to receive subsequent SIBs according to the access procedure of the LTE system, but since the MTC system is deployed independently, in fact, at the current frequency point where the MTC system is located, there is no subsequent transmission of SIBs for the LTE user, and therefore the ue may attempt to receive SIBs for multiple times (at the current frequency point where the MTC system is located) and finally fails, thereby causing the ue to perform useless work and causing unnecessary power consumption.

Therefore, the deployment mode information is set in the MIB to indicate that the MTC system is deployed independently or based on the LTE system. Therefore, after the user equipment of the LTE system acquires the MIB, whether the MTC system is independently deployed or deployed based on the LTE system can be determined according to the deployment mode information in the MIB.

When the ue determines that the MTC system is deployed independently according to the deployment mode information, the ue may know that there is no subsequent transmission for the LTE user at the current frequency point where the MTC system is located, so that the ue may give up performing actions that need to be performed after receiving the MIB in the access process of the LTE system, such as receiving an SIB and subsequent actions. Thereby unnecessary power consumption can be avoided. In addition, it should be noted that after the ue abandons performing the subsequent action, the ue may continue to detect other possible frequency points to attempt to receive PSS and SSS signals of the LTE system, so as to access the LTE system.

In the technical scheme, in the process of the MTC system, after the MIB is received, the deployment mode information in the MIB is obtained, and the deployment mode information is used for indicating that the MTC system is independently deployed or deployed based on the first communication system; and when the deployment mode information indicates that the MTC system is independently deployed, giving up executing the specified action, wherein the specified action comprises an action which needs to be executed after the MIB is received in the access process of the first communication system. Through the technical scheme provided by the disclosure, the user equipment using the first communication system can avoid unnecessary power consumption under the condition that the MTC system is independently deployed.

Further, fig. 2 is a flowchart illustrating an access method of another machine type communication system according to an exemplary embodiment, where the method is used in a user equipment, and the method may further include the following steps based on the method illustrated in fig. 1.

In step S13, when the deployment mode information indicates that the MTC system is deployed based on the first communication system, the specified action is continuously performed.

Taking the first communication system as an LTE system as an example, when the deployment mode information indicates that the MTC system is deployed based on the LTE system, the current frequency point where the MTC system is located is indicated, and subsequent transmission for the LTE system user is performed subsequently, and the user equipment does not need to go to other frequency points to detect the LTE system again. Therefore, after acquiring the MIB, the ue needs to perform subsequent actions, i.e. continue to receive SIBs, to acquire subsequent parameters related to random access.

The method for setting the deployment mode information is described as follows:

in an implementation, the deployment mode information may be a value of a deployment mode flag bit set in a reserved bit in the MIB, and accordingly, fig. 3 is a flowchart illustrating an access method of another machine type communication system according to an exemplary embodiment, where the method is used in a user equipment, as shown in fig. 3, and the step of obtaining the deployment mode information in the MIB at step S11 may include the following steps.

In step S111, the value of the deployment mode flag bit among the reserved bits set in the MIB is acquired.

As described above, a reserved bit of 5 bits is set in the current MIB, and therefore one or more bits of the MIB can be selected to set deployment mode information, which is called a deployment mode flag.

When the deployment mode flag bit is one bit, the deployment mode flag bit is used for indicating that the MTC system is deployed independently or based on the first communication system.

When the deployment mode flag bit is a plurality of bits, the deployment mode flag bit is used for indicating that the MTC system is deployed independently or based on the first communication system, and a frequency difference range of a frequency point of the adjacent first communication system relative to a current frequency point of the MTC system, where the adjacent first communication system is the first communication system whose frequency point is closest to the current frequency point of the MTC system. Accordingly, as shown in fig. 3, step S12 becomes: when the value of the deployment mode flag bit indicates that the MTC system is independently deployed, giving up executing a specified action, wherein the specified action comprises an action which needs to be executed after the MIB is received in the access process of the first communication system; step S13 becomes: when the value of the deployment mode flag bit indicates that the MTC system is deployed based on the first communication system, the specified action is continuously executed. And, when the deployment mode flag bit is a plurality of bits, the method may further include: after the prescribed action is abandoned, the adjacent first communication system is detected according to the frequency difference range.

For example, taking the first communication system as an LTE system as an example, the deployment mode flag may occupy 1 bit in the reserved bits of the MIB, and then the value of the deployment mode flag may use a one-bit binary number to indicate that the MTC system is deployed independently or based on the LTE system, for example, when the deployment mode flag is 0, the MTC system is deployed based on the LTE system; when the deployment mode flag bit is 1, the MTC system is independently deployed.

For the case that the deployment mode flag bit is multiple bits, taking 3 bits as an example, as shown in table 1, the deployment mode flag bit may occupy 3 bits in the reserved bits of the MIB, and the value of the deployment mode flag bit may use a three-bit binary number to represent the deployment mode, and indicate the frequency point position of the LTE system (of the MTC system) near the current frequency point (that is, the frequency difference range of the frequency point of the adjacent LTE system relative to the current frequency point of the MTC system).

TABLE 1

It should be noted that the above expression method that the deployment mode flag bit adopts 3 bits is exemplary, but not limited to this, for example, 2 bits, 4 bits, or 5 bits may also be adopted according to actual requirements. A 4-bit scheme may be used here, as shown in table 2.

TABLE 2

In which, 4 bits are used to represent the deployment mode flag bit, and at most 16 cases can be represented, so in addition to the several cases shown in table 2, more cases can be added as needed, which is not listed here.

In summary, when the deployment mode flag indicates that the MTC system is deployed based on the LTE system, the SIB receiving operation is continuously performed; when the deployment mode flag indicates that the MTC system is deployed independently, the user equipment abandons execution of subsequent SIB receiving actions, tries to detect the LTE system at other frequency points, and can acquire the frequency difference range of the frequency point of the adjacent LTE system relative to the current frequency point of the MTC system according to the deployment mode flag when the deployment mode flag has a plurality of bits, so that the LTE system can be detected more quickly.

In another implementation, the deployment mode information may be a value of a deployment mode flag bit set in a reserved bit in the MIB and a value of a first communication system location flag bit of a PHICH configuration field set in the MIB, and accordingly, fig. 4 is a flowchart illustrating an access method of another machine type communication system according to an exemplary embodiment, and as shown in fig. 4, the step of obtaining the deployment mode information in the MIB at step S11 may include the following steps.

In step S112, the value of the deployment mode flag bit among the reserved bits set in the MIB and the value of the first communication system location flag bit of the PHICH configuration field set in the MIB are acquired.

The deployment mode flag bit is a bit used for indicating that the MTC system is deployed independently or based on the first communication system; the first communication system position flag bit is a plurality of bits and is used for indicating the frequency difference range of the frequency point of the adjacent first communication system relative to the current frequency point of the MTC system, and the adjacent first communication system is the first communication system with the frequency point closest to the current frequency point of the MTC system.

Accordingly, as shown in fig. 4, step S12 becomes: when the value of the deployment mode flag bit indicates that the MTC system is independently deployed, giving up executing a specified action, wherein the specified action comprises an action which needs to be executed after the MIB is received in the access process of the first communication system; step S13 becomes: when the value of the deployment mode flag bit indicates that the MTC system is deployed based on the first communication system, the specified action is continuously executed. Further, after step S12, the method may further include: in step S14, after the designated action is abandoned, the adjacent first communication system is detected based on the frequency difference range indicated by the value of the first communication system location flag.

Taking the first communication system as an LTE system as an example, similar to the method in step S111, the deployment mode flag may occupy 1 bit in the reserved bits of the MIB, and then the value of the deployment mode flag may use a one-bit binary number to indicate that the MTC system is deployed independently or based on the LTE system, for example, when the deployment mode flag is 0, the MTC system is deployed based on the LTE system; when the deployment mode flag bit is 1, the MTC system is independently deployed.

On the other hand, if the MTC system is deployed based on the LTE system, the PHICH configuration field in the MIB is still used to indicate PHICH channel configuration information. However, for an independently deployed MTC system, the frequency point position of the LTE system (of the MTC system) near the current frequency point (that is, the frequency difference range between the frequency point of the adjacent LTE system and the current frequency point of the MTC system) may be indicated by using 3 bits of the PHICH configuration domain. Namely, 3 bits of the PHICH configuration field are used as the first communication system location flag bit, and the value thereof can be represented by three-bit binary numbers, which respectively represent different frequency point locations of the nearby LTE system. As shown in table 3:

TABLE 3

The above method for indicating the frequency point position of the nearby LTE system by using 3 bits in the PHICH configuration domain as the LTE system position flag bit is exemplary, but not limited thereto, and for example, 2 bits may also be used according to actual requirements.

In summary, when the deployment mode flag indicates that the MTC system is deployed based on the LTE system, the SIB receiving operation is continuously performed; when the deployment mode flag bit indicates that the MTC system is deployed independently, the user equipment abandons execution of subsequent SIB receiving actions, tries to detect the LTE system at other frequency points, and can acquire a frequency difference range of a frequency point of an adjacent LTE system relative to a current frequency point of the MTC system according to a value of a PHICH configuration domain, so that the LTE system can be detected more quickly.

In the technical scheme, in the process of the MTC system, after the MIB is received, deployment mode information in the MIB is acquired, wherein the deployment mode information is used for indicating that the MTC system is independently deployed or deployed based on the first communication system; and when the deployment mode information indicates that the MTC system is independently deployed, giving up executing the specified action, wherein the specified action comprises an action which needs to be executed after the MIB is received in the access process of the first communication system. Through the technical scheme provided by the disclosure, the user equipment using the first communication system can avoid unnecessary power consumption under the condition that the MTC system is independently deployed.

Fig. 5 is a flowchart illustrating an access method of another machine type communication system according to an exemplary embodiment, and the method, as shown in fig. 5, used in a base station may include the following steps.

Step S21, when the ue accesses the MTC system, the ue sends a synchronization signal to the ue, where the ue is a ue of the first communication system.

The first communication system may be an LTE system supporting an MTC system, and the synchronization signal includes the PSS and the SSS, which are used for performing downlink synchronization when the ue receives the synchronization signal. The receiving procedure of the PSS and the SSS by the user equipment has been described in the introduction of the application scenario, and is not described herein again.

Step S22, generating an MIB according to the deployment mode of the MTC system, where the MIB includes deployment mode information, and the deployment mode information is used to indicate that the MTC system is deployed independently or based on the first communication system.

Step S23, the MIB is sent to the user equipment.

After generating the MIB, the base station transmits the MIB through PBCH, and the user equipment receives the MIB by detecting PBCH, where the method for the user equipment to receive the MIB is described in the application scenario introduction, and is not described herein again.

After receiving the MIB, the ue may determine whether the MTC system is deployed independently or based on the first communication system by obtaining the deployment mode information in the MIB. After determining that the MTC system is deployed independently or based on the first communication system, the user equipment may perform steps S12 or S13 accordingly.

In one implementation, the generating a MIB according to the deployment mode of the MTC system in step S22, where the MIB includes deployment mode information, and the deployment mode information is used to indicate that the MTC system is deployed independently or based on the first communication system, and may include:

generating a MIB according to the deployment mode of the MTC system, wherein a deployment mode flag bit is set in a reserved bit in the MIB.

The deployment mode flag bit may be one bit or multiple bits. Since the current MIB is provided with reserved bits of 5 bits, one or more bits thereof can be selected as the deployment mode flag.

When the deployment mode flag bit is one bit, the deployment mode flag bit is used for indicating that the MTC system is deployed independently or based on a first communication system; when the deployment mode flag is a plurality of bits, the deployment mode flag is used to indicate that the MTC system is deployed independently or based on a first communication system, and a frequency difference range of a frequency point of an adjacent first communication system with respect to a current frequency point of the MTC system, where the adjacent first communication system is a first communication system whose frequency point is closest to the current frequency point of the MTC system.

For example, taking the first communication system as an LTE system as an example, the deployment mode flag may occupy 1 bit in the reserved bits of the MIB, and then the value of the deployment mode flag may use a one-bit binary number to indicate that the MTC system is deployed independently or based on the LTE system, for example, when the deployment mode flag is 0, the MTC system is deployed based on the LTE system; when the deployment mode flag bit is 1, the MTC system is independently deployed. Therefore, when the base station generates the MIB, the value of the deployment mode flag bit in the MIB may be set to 0 or 1 according to whether the actual deployment mode of the MTC system is deployed independently or based on the LTE system. Or, the deployment mode flag may occupy 3 bits in the reserved bit of the MIB, for example, the implementation manner shown in table 1 indicates the deployment mode of the MTC system, and also indicates the frequency point position of the LTE system (of the MTC system) near the current frequency point (i.e., the frequency difference range between the frequency point of the adjacent LTE system and the current frequency point of the MTC system), which may be referred to the content shown in table 1, and is not described again. In addition, the above expression method that the deployment mode flag bit adopts 3 bits is exemplary, including but not limited to this, for example, 2 bits, 4 bits, or 5 bits may also be adopted according to actual requirements. A 4-bit scheme may be used here, as shown in table 2 above.

In the implementation manner, when the deployment mode flag bit in the MIB sent by the base station indicates that the MTC system is deployed based on the LTE system, the ue continues to perform an SIB receiving action; when the deployment mode flag bit indicates that the MTC system is deployed independently, the user equipment abandons execution of subsequent SIB receiving actions, tries to detect the LTE system at other frequency points, and when the deployment mode flag bit is a plurality of bits, the deployment mode flag bit can also indicate the user equipment to acquire a frequency difference range of the frequency point of the adjacent LTE system relative to the current frequency point of the MTC system according to the deployment mode flag bit, so that the user equipment can detect the LTE system more quickly.

In another implementation, the generating a MIB according to the deployment mode of the MTC system in step S22, where the MIB includes deployment mode information, and the deployment mode information is used to indicate that the MTC system is deployed independently or based on the first communication system, and may include:

generating an MIB according to the deployment mode of the MTC system, wherein a deployment mode flag bit is arranged in a reserved bit in the MIB, and a PHICH configuration domain in the MIB is provided with a first communication system position flag bit.

Wherein, the deployment mode flag bit is a bit used for indicating that the MTC system is deployed independently or based on a first communication system; the first communication system position flag bit is a plurality of bits and is used for indicating the frequency difference range of the frequency point of the adjacent first communication system relative to the current frequency point of the MTC system, and the adjacent first communication system is the first communication system with the frequency point closest to the current frequency point of the MTC system.

Taking the first communication system as an LTE system as an example, the deployment mode flag may occupy 1 bit in the reserved bits of the MIB, and then the value of the deployment mode flag may use a one-bit binary number to indicate that the MTC system is deployed independently or based on the LTE system, for example, when the deployment mode flag is 0, the MTC system is deployed based on the LTE system; when the deployment mode flag bit is 1, the MTC system is independently deployed. Therefore, when the base station generates the MIB, the value of the deployment mode flag bit in the MIB may be set to 0 or 1 according to whether the actual deployment mode of the MTC system is deployed independently or based on the LTE system.

On the other hand, if the MTC system is deployed based on the LTE system, the PHICH configuration field in the MIB may still be used to indicate PHICH channel configuration information. However, for an independently deployed MTC system, 3 bits of the PHICH configuration domain may be used as LTE system location flag bits to indicate a frequency point location of the LTE system (of the MTC system) near a current frequency point (that is, a frequency difference range between a frequency point of an adjacent LTE system and the current frequency point of the MTC system). See the above table 3, and will not be described further. In addition, the above expression method that the deployment mode flag bit adopts 3 bits is exemplary, including but not limited to this, for example, 2 bits may also be adopted according to actual needs.

Therefore, when the base station generates the MIB, the value of the PHICH configuration domain, that is, the value of the LTE system location flag bit, can be set according to the frequency point location of the adjacent LTE system.

In the implementation manner, when the deployment mode flag bit in the MIB sent by the base station indicates that the MTC system is deployed based on the LTE system, the ue continues to perform an SIB receiving action; when the deployment mode flag bit indicates that the MTC system is deployed independently, the user equipment abandons execution of subsequent SIB receiving actions, tries to detect the LTE system at other frequency points, and can acquire a frequency difference range of a frequency point of an adjacent LTE system relative to a current frequency point of the MTC system according to a value of the PHICH configuration domain, so that the LTE system can be detected more quickly.
