Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for processing a synchronization signal, a network device, and a terminal device.
Background
In an LTE (Long Term Evolution) system, cell search is a process of detecting a cell downlink synchronization signal when a terminal device is turned on or cell handover is required. The cell search specifically includes time synchronization detection, frequency synchronization detection, cell ID detection, and the like, and is ready for subsequent channel estimation and broadcast channel reception.
In the LTE system, downlink synchronization signals are divided into Primary Synchronization Signals (PSS) and Secondary Synchronization Signals (SSS). The advantages of using the primary and secondary synchronization signals are that the terminal device can be ensured to accurately and rapidly detect the primary synchronization signal, and the secondary synchronization signal is detected on the premise of knowing the primary synchronization signal, so that the cell search speed is increased.
Fig. 1 and 2 show the location schematic diagrams of PSS and SSS for LTE (fdd) and TD-LTE, respectively. As shown in fig. 2, PSS occupies the 3 rd symbol of subframes 1, 6, and SSS occupies the last symbol of subframes 0, 5. In addition, the LTE system supports multiple transmission bandwidth configurations, and in order to ensure relative fixing of PSS and SSS positions and implementation simplification of detection algorithms under various system bandwidths, PSS and SSS signals are always located at a position of 1.08MHz (6 PRB blocks) in the center of the entire system bandwidth in the frequency domain.
A Zadoff-Chu sequence is adopted as a main synchronous signal in an LTE system, and an m sequence is adopted as an auxiliary synchronous signal. The cell ID number is determined by the primary synchronization sequence number and the secondary synchronization sequence number. The primary synchronization sequence comprises 3 Zadoff-Chu sequences, and the Zadoff-Chu sequence with the length of 63 cuts off the symbol on the direct current carrier subcarrier to obtain a sequence with the length of 62 symbols. The master synchronization sequence has the characteristics of low peak-to-average ratio of a forming signal, strong frequency deviation resistance and the like. The secondary synchronization signal is a sequence with the length of 62, which is obtained by cross-cascading two m sequences with the length of 31. In a radio frame, the cross-cascade mode of the auxiliary synchronization signal in the first half frame is opposite to the cross-cascade mode of the auxiliary synchronization signal in the second half frame, and the design enables the UE to distinguish the initial position of the radio frame through the sequence of the detection sequences. In order to improve the identification degree of the synchronous signals among different cells, the secondary synchronous signals are scrambled by using two groups of scrambling codes. The first group of scrambling codes is determined by the index number of the primary synchronization sequence and scrambles two groups of secondary synchronization sequences together, and the second group of scrambling codes is determined by the first group of secondary synchronization sequences and scrambles the secondary synchronization sequences on odd subcarriers. The secondary synchronization signal after being scrambled twice has better correlation characteristics, and the secondary synchronization signal can be more accurately detected after the main synchronization signal is correctly detected.
The downlink time synchronization detection is the first step in cell initial search, and the basic principle is that terminal equipment uses a local synchronization sequence and a received signal to perform synchronization correlation, so as to obtain an expected peak value, and the position of a synchronization signal is judged according to the peak value. The time domain synchronous detection in the LTE system is divided into two steps: the first step is to detect the primary synchronization signal, and after the primary synchronization signal is detected, the second step is to detect the secondary synchronization signal, that is, to detect the primary synchronization signal, based on the fixed relationship between the primary synchronization signal and the secondary synchronization signal. When the terminal equipment is in an initial access state, the bandwidth of an access cell is unknown, and the primary synchronization signal and the secondary synchronization signal are in the center of the whole bandwidth and occupy 1.08MHz bandwidth. Therefore, at the time of initial access, the UE first scans on a frequency grid with 100KHz intervals in the supported operating frequency band, and performs detection of the primary synchronization channel on each frequency point. In this process, the terminal device detects only the presence of the primary synchronization signal on the 1.08MHz band.
When the PSS signal is detected, the sequence number of the primary synchronization sequence is obtained. After the receiving and detecting of the PSS signal are completed, the detection of the subframe CP type also needs to be completed. Because the system may be a normal CP or an extended CP, there are two possibilities for the distance between the corresponding PSS and SSS, and the distance needs to be identified by the terminal device in a blind detection manner, usually by using the distance between the PSS and SSS correlation peaks for judgment.
After the CP type of the subframe is determined, the position of an SSS signal and an SSS sequence are also determined. Because the auxiliary synchronization sequences are more and scrambling is adopted twice, the detection process is relatively complex. From an implementation point of view, the secondary synchronization sequence can reduce the computational complexity through frequency domain detection with the known PSS position. In addition, the LTE system distinguishes between FDD and TDD systems using the difference in PSS and SSS locations.
In the future 5G mobile communication system, due to the introduction of high-frequency large bandwidth and the adoption of a unified mixed frame structure design for FDD and TDD, the design of a synchronous signal is not limited to a system central frequency band of 1.08 MHz; meanwhile, the 5G supports multiple scenes such as independent networking and non-independent networking, authorized spectrum and non-authorized spectrum, eMBB, URLLC, mMTC and the like, and the frame structure parameters also support multiple subcarrier intervals SCS and cyclic prefixes CP according to whether the system carrier frequency is high-frequency or low-frequency. The mapping and design of the existing LTE synchronization signal can not effectively support the cell search of various 5G scenes, and has the defects of lack of forward compatibility and optimization capability in the aspect of subsequent access systems of terminal equipment.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
First embodiment
As shown in fig. 3, an embodiment of the present invention provides a method for processing a synchronization signal, where the method specifically includes:
step 31: and the network equipment configures hidden system information corresponding to the terminal equipment.
The network device refers to a network side device, and generally has configuration and access capabilities, for example, a base station, an access point, and other devices. The network equipment determines hidden system information needing to be indicated to the terminal equipment according to information such as the cell type of a service cell served by the network equipment, transmission parameter configuration and the like. The hidden system information corresponding to different information such as cell type and transmission parameter configuration is different.
Step 32: and the network equipment configures the position information for sending the synchronous signal according to the state of the implicit system information.
The synchronization signal comprises a primary synchronization signal and/or a secondary synchronization signal, and the position information comprises time domain position information, frequency domain position information and/or code domain position information. The different states of the hidden indication system information correspond to different position information of the synchronization signals, and the different position information means that the time domain position information, the frequency domain position information and/or the code domain position information allocated to the primary synchronization signal and/or the secondary synchronization signal are different. The mapping relation between the position information of the synchronization signal and the state of the hidden system information is configured in advance, and the position information of the synchronization signal can be determined by determining the state of the hidden system information. Further, the location information allocated by the network device for the synchronization signal is not fixed, that is, in one period, the time domain location, the frequency domain location, and/or the code domain location of the primary synchronization signal and/or the secondary synchronization signal are not completely fixed, which implies that the states of the system information are different and the corresponding locations are different.
Step 33: and the network equipment sends the synchronous signal according to the position information.
The network equipment sends the synchronous signals to the terminal equipment through transmission resources (time domain resources, frequency domain resources and code domain resources) corresponding to the position information which is allocated for the synchronous signals in advance, so that the terminal equipment obtains corresponding position information through detecting the synchronous signals, and analyzes corresponding hidden system information according to the position information.
The embodiment of the invention obtains additional system information through the position information of the main synchronizing signal and/or the auxiliary synchronizing signal, can reduce the signaling overhead of the system information, saves network transmission resources, and can further provide an optimization strategy for the terminal equipment to access the network and the network to regulate and control initial access.
Second embodiment
The first embodiment briefly describes the method for processing the synchronization signal according to the present invention, and the following embodiment will further describe the method with reference to the drawings and specific application scenarios.
As shown in fig. 3, the method for processing a synchronization signal according to the embodiment of the present invention specifically includes the following steps:
step 31: and the network equipment configures hidden system information corresponding to the terminal equipment.
Step 32: and the network equipment configures the position information for sending the synchronous signal according to the state of the implicit system information.
Step 33: and the network equipment sends the synchronous signal according to the position information.
The hidden system information includes but is not limited to: first bit information indicating a cell type of a serving cell and/or second bit information indicating a transmission parameter configuration of the serving cell. The implementation of step 32 specifically includes, but is not limited to, the following scenarios:
scene one: and the network equipment configures the position information with fixed frequency domain position and periodic time domain position offset for the main synchronous signal according to the state of the hidden system information. The time domain position offset of the primary synchronization signal configured in different states of the hidden system information is different. The scene is a scene of a fixed frequency domain and time domain offset of the primary synchronization signal, and specific position information of the primary synchronization signal can be shown in fig. 4 and 5. The main synchronization signal is sent periodically, the frequency domain relative position of each sending period is fixed, and at least two position relations exist in the time domain in one sending period, wherein one is the fixed time domain relative position configured by the system to simplify the detection of the main synchronization signal, namely the main synchronization signal adopts T1 as an interval period; the other is the position of the periodic offset of the system configuration, namely the main synchronization signal takes T1+ delta T as the interval period; thus, at least 1 bit of system information can be hidden by configuring the period of the primary synchronization signal in the time domain. It should be noted that if the periodicity offset configured for the primary synchronization signal by the network device is more than Δ T1, Δ T2 …, i.e. the transmission period T e (T1, T1+ Δ T1, T1+ Δ T2 ….), the system information of more than one bit can be hidden. Assuming that the subcarrier spacing is 15KHz and N × 15KHz, the primary synchronization signal or the secondary synchronization signal may adopt the same or different parameter configuration as the data transmission, taking 15KHz as an example, fig. 4 shows a schematic diagram of the position information of the primary synchronization signal when the primary synchronization signal and the data transmission are in the same or different parameter configuration, that is, the periodicity offset of the primary synchronization signal corresponding to the same implicit system information indication is 0 (shown in the first row), and the periodicity offset of the primary synchronization signal corresponding to the different implicit system information indication is Δ t (shown in the second row). Similarly, fig. 5 shows a schematic diagram of the position information of the master synchronization signal when the master synchronization signal and the data transmission have the same or different parameter configurations when the subcarrier spacing is 30 KHz.
Scene two: and the network equipment configures position information with fixed time domain positions and periodic deviation of frequency domain positions for the main synchronizing signal according to the state of the hidden indication system information. The frequency domain position offset of the primary synchronization signal configured in different states of the implicit system information is different. The scene is a scene in which the primary synchronization signal has a fixed time domain and a fixed frequency domain, and specific position information of the primary synchronization signal can be shown in fig. 6. The main synchronization signal is sent periodically, the time domain relative position of each sending period is fixed, and at least two position relations exist on the frequency domain in one sending period, one is that the system configures the fixed frequency domain relative position to simplify the detection of the main synchronization signal, namely, the main synchronization signal adopts f1 as the frequency domain transmission resource; the other is the frequency domain position of the system configuration periodic offset, namely the main synchronization signal adopts f1+ delta f as the interval period; thus, at least 1 bit of system information can be hidden by configuring the period of the primary synchronization signal in the frequency domain. It should be noted that if the periodicity offset configured for the primary synchronization signal by the network device is more than Δ f1, Δ f2 …, i.e. the transmission period T e (f1, f1+ Δ f1, f1+ Δ f2 ….), the system information of more than one bit can be hidden. Fig. 6 also shows a schematic diagram of position information of a primary synchronization signal when the primary synchronization signal and data transmission are configured with the same or different parameters, that is, it indicates that the frequency domain periodicity offset of the primary synchronization signal corresponding to the same system information indication is 0 (shown in the first row and the second row), and it indicates that the frequency domain periodicity offset of the primary synchronization signal corresponding to the different system information indication is Δ f (shown in the third row and the fourth row).
Scene three: and the network equipment configures position information with fixed time domain position and fixed frequency domain position for the main synchronous signal and configures position information with fixed frequency domain position and periodic time domain position offset for the auxiliary synchronous signal according to the state of the hidden indication system information. The offset of the time domain position of the secondary synchronization signal configured in different states of the implicit system information is different. The scene is a scene in which the primary synchronization signal has a fixed frequency domain and a time domain, and the secondary synchronization signal has a fixed frequency domain and a time domain offset, and specific position information of the primary synchronization signal can be shown in fig. 7. The main synchronization signal and the auxiliary synchronization signal are sent periodically, the frequency domain relative position of each sending period is fixed, at least two position relations exist in the time domain of the auxiliary synchronization signal in one sending period, one is the fixed time domain relative position configured by the system, so as to simplify the detection of the auxiliary synchronization signal, namely the auxiliary synchronization signal adopts T1 as an interval period; the other is the position of the periodic offset configured by the system, namely the auxiliary synchronization signal adopts T1+ delta T as an interval period; thus, at least 1 bit of system information can be hidden by configuring the period of the secondary synchronization signal in the time domain. It should be noted that if the periodicity offset configured for the secondary synchronization signal by the network device is more than Δ T1, Δ T2 …, i.e. the transmission period T e (T1, T1+ Δ T1, T1+ Δ T2 ….), the system information of more than one bit can be hidden. Fig. 7 shows a schematic diagram of position information of the primary synchronization signal and the secondary synchronization signal when the primary synchronization signal and/or the secondary synchronization signal are configured with the same or different parameters as the data transmission, that is, the implicit system information indicates that the periodic offset of the corresponding secondary synchronization signal is 0 (shown in the first row) when the system information indicates that the signals are the same, and the implicit system information indicates that the periodic offset of the corresponding secondary synchronization signal is Δ t (shown in the second row) when the system information indicates that the signals are not the same.
Scene four: the network equipment configures position information with fixed time domain position and fixed frequency domain position for the main synchronous signal and configures position information with fixed time domain position and periodic offset frequency domain position for the auxiliary synchronous signal according to the state of the hidden indication system information; the frequency domain position offset of the secondary synchronization signal configured in different states of the implicit system information is different. The scene is a scene in which the fixed time domain and the frequency domain of the primary synchronization signal and the fixed time domain and the frequency domain of the secondary synchronization signal are shifted, and specific position information of the primary synchronization signal and the secondary synchronization signal can be referred to fig. 8. The main synchronization signal and the auxiliary synchronization signal are sent periodically, the time domain relative position of each sending period is fixed, and the auxiliary synchronization signal has at least two position relations in the frequency domain in one sending period, wherein one is the fixed frequency domain relative position configured by the system to simplify the detection of the auxiliary synchronization signal, namely, the auxiliary synchronization signal adopts f1 as the frequency domain transmission resource; the other is that the system configures the frequency domain position of periodic offset, namely the secondary synchronization signal adopts f1+ delta f as an interval period; thus, at least 1 bit of system information can be hidden by configuring the period of the secondary synchronization signal on the frequency domain. It should be noted that if the periodicity offset configured for the secondary synchronization signal by the network device is more than Δ f1, Δ f2 …, i.e. the transmission period T e (f1, f1+ Δ f1, f1+ Δ f2 ….), the system information of more than one bit can be hidden. Fig. 8 also shows a schematic diagram of position information of the primary synchronization signal and the secondary synchronization signal when the primary synchronization signal or the secondary synchronization signal and data transmission are configured with the same or different parameters, that is, the hidden system information indicates that the frequency domain periodicity offset of the corresponding secondary synchronization signal is 0 (shown in the first row and the second row) when the system information indicates that the signals are the same, and the hidden system information indicates that the frequency domain periodicity offset of the corresponding secondary synchronization signal is Δ f (shown in the third row and the fourth row) when the system information indicates that the signals are different.
Scene five: the network equipment configures position information with fixed time domain position and fixed frequency domain position for the main synchronous signal and configures position information with periodic offset of both time domain position and frequency domain position for the auxiliary synchronous signal according to the state of the hidden indication system information; the offset of the time domain position or the frequency domain position of the secondary synchronization signal configured in different states of the implicit system information is different. The scene is a scene in which the fixed time domain and the fixed frequency domain of the primary synchronization signal and the time domain and the frequency domain of the secondary synchronization signal are both shifted, and specific position information of the primary synchronization signal and the secondary synchronization signal can be referred to fig. 9. The primary synchronization signal and the secondary synchronization signal are sent periodically, the time domain relative position of each sending period is fixed, at least four position relations exist in the frequency domain of the secondary synchronization signal in one sending period, the first method is that the system configures the fixed time domain relative position to simplify the detection of the secondary synchronization signal, namely the secondary synchronization signal adopts T1 as an interval period; the second is the position of the periodic offset of the system configuration, namely the auxiliary synchronization signal adopts T1+ delta T as the interval period; the third is that the system configures a fixed frequency domain relative position to simplify the detection of the secondary synchronization signal, i.e. the secondary synchronization signal adopts f1 as a frequency domain transmission resource; the fourth is the frequency domain position of the periodic offset of the system configuration, i.e. the secondary synchronization signal takes f1+ Δ f as the interval period. Thus, at least 2 bits of system information can be hidden by configuring the period of the secondary synchronization signal in the time domain. It should be noted that if the network device configures a plurality of periodic offsets Δ T1, Δ T2 … for the secondary synchronization signal, that is, a transmission period T e (T1, T1+ Δ T1, T1+ Δ T2 ….), the system information of a plurality of bits may be hidden; or, when the periodicity offset configured for the secondary synchronization signal by the network device is multiple Δ f1, Δ f2 …, etc., that is, the transmission period T e (f1, f1+ Δ f1, f1+ Δ f2 ….), multiple bits of system information may be hidden. Fig. 9 shows a schematic diagram of position information of a primary synchronization signal and a secondary synchronization signal in different states of implicit system information, that is, when the implicit system information indicates a first state, time domain and frequency domain periodic offsets of the corresponding secondary synchronization signal are both 0 (shown in the first row and the second row); when the implicit system information indicates the second state, the time domain periodic offset of the corresponding secondary synchronization signal is 0 and the frequency domain periodic offset is Δ f (shown in the third row and the fourth row); when the implicit system information indicates the third state, the frequency domain periodic offset of the corresponding auxiliary synchronization signal is 0 and the time domain periodic offset is Δ t (shown in the fifth line and the sixth line); when the implicit system information indicates the fourth state, the frequency domain periodicity offset of the corresponding secondary synchronization signal is Δ f and the time domain periodicity offset is Δ t (shown in the seventh row and the eighth row).
Scene six: the network equipment configures the position information of the periodic deviation of the time domain position and/or the frequency domain position for the main synchronous signal and configures the position information of the periodic deviation of the time domain position and/or the frequency domain position for the auxiliary synchronous signal according to the state of the hidden indication system information; the time domain position or frequency domain position offset of the primary synchronization signal and/or the secondary synchronization signal configured in different states of the implicit system information is different. The scene means that the primary synchronization signal does not fix the time domain and frequency domain positions, and the secondary synchronization signal is subjected to position offset on the time domain and the frequency domain on the basis of the time domain and the frequency domain of the primary synchronization signal. The scene has more combination modes so as to hide more bits of system information, and the indication mode is similar to the modes described in the first scene to the fifth scene, and therefore, the description is omitted here. It should be noted that, when the complexity and the calculation amount of the terminal device in the time-frequency domain position detection of the synchronization signal are comprehensively considered, the implementation schemes of one scene to five scenes can be optimized according to the bit number of the implicit system information.
In summary, the embodiments of the present invention introduce various application scenarios in which the network device allocates transmission resources for the synchronization signals, and the allocation manner of the location information of the synchronization signals has strong compatibility, and can simultaneously satisfy various scenarios such as a TDD system, an FDD system, an independent networking and non-independent networking, a licensed spectrum and an unlicensed spectrum, an eMBB, a URLLC, and an mtc. In addition, the network equipment configures the position information of the synchronous signal according to the configured state of the hidden system information, so that the terminal equipment can obtain additional hidden system information through the position information of the main synchronous signal and/or the auxiliary synchronous signal, the signaling overhead of the system information can be reduced, the network transmission resource can be saved, and an optimization strategy can be further provided for the terminal equipment to access the network and the network to regulate and control initial access.

And the terminal equipment receives and detects the synchronization information to acquire the position information of the synchronization signal.

Fifth embodiment
As shown in fig. 13, the method for processing a synchronization signal according to the embodiment of the present invention specifically includes the following steps:
step 131: and the terminal equipment determines the frequency domain position of the main synchronizing signal through full-band scanning.
Step 132: the terminal equipment carries out correlation processing on the local synchronization sequence and the received main synchronization signal, and determines the time domain position of the main synchronization signal.
The terminal device receives and detects the synchronization signal to obtain the position information of the synchronization signal, and taking the primary synchronization signal as an example, specifically, the first detection method is as follows: the terminal equipment firstly scans in the working frequency band by taking the system synchronous frequency grid interval as a unit, detects a main synchronous signal on each frequency point and confirms whether the main synchronous signal exists on the transmission bandwidth of the main synchronous signal; further, the terminal device uses the local synchronization sequence and the received signal to perform synchronization correlation, obtains an expected peak value, and determines the time domain position of the main synchronization signal according to the peak value. According to the position relation of two main synchronizing signals existing in the time domain of the system, the terminal equipment adopts a blind detection mode to identify, and finally the receiving and the detection of the main synchronizing signals are finished.
And a second detection mode: the terminal equipment firstly scans in the working frequency band by taking the system synchronous frequency grid interval as a unit, detects a main synchronous signal on each frequency point and confirms whether the main synchronous signal exists on the transmission bandwidth of the main synchronous signal; further, the terminal device uses the local synchronization sequence and the received signal to perform synchronization correlation to obtain an expected peak value, the time domain position of the primary synchronization signal is judged according to the peak value, the terminal device adopts a blind detection mode to identify according to the position relation of two types of primary synchronization signals existing in the frequency domain of the system, and finally the receiving and the detection of the primary synchronization signal are completed.
Take the simultaneous detection of the primary synchronization signal and the secondary synchronization signal as an example. And a third detection mode: the terminal equipment firstly scans in the working frequency band by taking the system synchronous frequency grid interval as a unit, detects a main synchronous signal on each frequency point and confirms whether the main synchronous signal exists on the transmission bandwidth of the main synchronous signal; further, the terminal equipment uses the local synchronization sequence and the received signal to carry out synchronization correlation to obtain an expected peak value, judges the time domain position of the main synchronization signal according to the peak value, completes the receiving and detection of the main synchronization signal and simultaneously obtains the frequency domain position information of the auxiliary synchronization signal; and then, according to the relative offset position relation between the main synchronization signal and the auxiliary synchronization signal in the time domain and the existence of two position relations between the auxiliary synchronization signal in the time domain, the terminal equipment adopts a blind detection mode to identify so as to complete the receiving and the detection of the auxiliary synchronization signal.
And a detection mode is four: the terminal equipment firstly scans in the working frequency band by taking the system synchronous frequency grid interval as a unit, detects a main synchronous signal on each frequency point and confirms whether the main synchronous signal exists on the transmission bandwidth of the main synchronous signal; further, the terminal equipment uses the local synchronization sequence and the received signal to carry out synchronization correlation to obtain an expected peak value, judges the time domain position of the main synchronization signal according to the peak value, completes the receiving and detection of the main synchronization signal and simultaneously obtains the time domain position information of the auxiliary synchronization signal; and then, according to the relative offset position relation between the main synchronization signal and the auxiliary synchronization signal in the frequency domain and the existence of two position relations between the auxiliary synchronization signal in the time domain, the terminal equipment adopts a blind detection mode to identify so as to complete the receiving and the detection of the auxiliary synchronization signal.
And a fifth detection mode: the terminal equipment firstly scans in the working frequency band by taking the system synchronous frequency grid interval as a unit, detects a main synchronous signal on each frequency point and confirms whether the main synchronous signal exists on the transmission bandwidth of the main synchronous signal; further, the terminal device uses the local synchronization sequence and the received signal to perform synchronization correlation, obtains an expected peak value, judges the time domain position of the main synchronization signal according to the peak value, and completes the receiving and detection of the main synchronization signal. And then, according to the relative offset position relationship between the main synchronization signal and the auxiliary synchronization signal in the time domain and the frequency domain and the four position relationships existing in the auxiliary synchronization signal in the time domain and the frequency domain, the terminal equipment adopts a blind detection mode to identify so as to complete the receiving and the detection of the auxiliary synchronization signal.
Step 133: and the terminal equipment judges and determines the corresponding implicit system information according to the position information of the synchronous signal.
After the terminal device acquires the position information of the synchronization signal, the corresponding hidden system information is determined according to the mapping relation between the position information and the hidden system information. Wherein, different position information corresponds to different hidden system information. Specifically, the following modes may be included and not limited:
the first method is as follows: and when the terminal equipment detects that the frequency domain position of the main synchronizing signal is fixed and the time domain position periodically deviates, determining corresponding hidden system information. The offset of the time domain position of the main synchronous signal corresponds to different states of the hidden system information.
The second method comprises the following steps: and when the terminal equipment detects that the time domain position of the main synchronizing signal is fixed and the frequency domain position periodically deviates, determining corresponding hidden display system information. The frequency domain position offset of the primary synchronization signal corresponds to different states of the implicit system information.
The third method comprises the following steps: and when the terminal equipment detects that the time domain position of the primary synchronization signal is fixed, the frequency domain position of the secondary synchronization signal is fixed and the time domain position periodically shifts, determining corresponding hidden display system information. And the offsets of the time domain positions of the auxiliary synchronous signals correspond to different states of the hidden display system information.
The method is as follows: and when the terminal equipment detects that the time domain position of the primary synchronization signal is fixed, the frequency domain position of the primary synchronization signal is fixed, the time domain position of the secondary synchronization signal is fixed and the frequency domain position of the secondary synchronization signal periodically shifts, determining corresponding hidden display system information. The offset of the frequency domain position of the auxiliary synchronization signal corresponds to different states of the implicit system information.
The fifth mode is as follows: and when the terminal equipment detects that the time domain position of the primary synchronization signal is fixed, the frequency domain position of the primary synchronization signal is fixed, and the time domain position and the frequency domain position of the secondary synchronization signal are periodically shifted, determining corresponding hidden display system information. The offset of the time domain position or the frequency domain position of the secondary synchronization signal corresponds to different states of the hidden system information.
The method six: and when the terminal equipment detects that the time domain position and/or the frequency domain position of the primary synchronization signal periodically shift and the time domain position and/or the frequency domain position of the secondary synchronization signal periodically shift, determining corresponding implicit system information. The offset of the time domain position or the frequency domain position of the primary synchronization signal and/or the secondary synchronization signal corresponds to different states of the implicit system information.
Therefore, different position information corresponds to different hidden system information, the signaling overhead of the system information can be reduced, and network transmission resources are saved to a certain extent.
Step 134: and the terminal equipment determines an access strategy of the corresponding service cell according to the implicit system information.
Specifically, when the terminal device detects that first bit information in the implicit system information indicates a cell type of a corresponding serving cell, a first access policy of the corresponding serving cell is determined. The following will describe it in detail with reference to specific examples.
Example one: and when the terminal equipment detects that the first bit information in the hidden indication system information indicates that the corresponding service cell is the non-independent networking system, ignoring the service cell. That is, the network device predefines 1-bit system information through the location information of the primary synchronization signal and/or the secondary synchronization signal to indicate that the system is an independent networking system (standby system) or a Non-independent networking system (Non-standby system) in the frequency band. The terminal equipment acquires the preset information of the system through the main synchronizing signal and/or the auxiliary synchronizing signal, if the system is a Non-standby system, the terminal equipment does not continue the initial access process (such as auxiliary synchronizing signal detection and BCH detection) on the carrier wave, and carries out cell search and synchronous detection on other frequency points again, so that the unnecessary initial access detection process of the terminal equipment on the Non-standby frequency point is reduced, and the terminal equipment can be accessed into the standby system more quickly.
Example two: when the terminal device detects that the first bit information in the implicit system information indicates the transmission resource type of the corresponding serving cell and/or neighboring cell, if the transmission resource type of the serving cell and/or neighboring cell does not meet the transmission requirement of the mobile terminal device, a cell reselection or cell handover process is started. That is, the network device predefines 1-bit or 2-bit system information for indicating the subframe or slot type of the cell in the frequency band according to the position information of the primary synchronization signal and/or the secondary synchronization signal. The terminal equipment acquires preset information of the system through the primary synchronization signal and/or the secondary synchronization signal, so that the terminal equipment prepares for cell reselection in advance according to whether the subframe or time slot type of the cell is DL/UL heavy; if the cell is found to be a full downlink DL cell and the terminal equipment urgently needs uplink transmission, the cell search and synchronous detection can be carried out again at other frequency points by ignoring the serving cell.
Example three: and when the terminal equipment detects that the first bit information in the implicit system information indicates that the corresponding service cell is in a long-time discontinuous transmission state, ignoring the service cell. The network device predefines 1-bit information through the position information of the primary synchronization signal and/or the secondary synchronization signal to indicate whether the base station of the local cell is in a DTX state under the local frequency band. And the terminal equipment acquires the preset information of the system through the position information of the main synchronizing signal and/or the auxiliary synchronizing signal. If the base station of the cell is in the long DTX state, the terminal equipment can ignore the serving cell and perform cell search and synchronous detection again at other frequency points.
Example four: and when the terminal equipment detects that the first bit information in the implicit system information indicates that the corresponding serving cell is prohibited to reside, ignoring the serving cell. The network device predefines 1-bit system information through the position information of the primary synchronization signal and/or the secondary synchronization signal to indicate whether the cell is prohibited to reside in the frequency band. And the terminal equipment acquires the preset information of the system through the position information of the main synchronizing signal and/or the auxiliary synchronizing signal. If the cell is forbidden to reside, the serving cell is ignored, and cell search and synchronous detection are carried out again at other frequency points. In addition, the network device may also predefine 2-bit system information through the location information of the primary synchronization signal and/or the secondary synchronization signal to indicate whether the cell is barred for emergency calls, barred for originating data, barred for originating signaling, and reserved fields in the frequency band. Further, a reserved field may be used for DTX indication.
In addition, when the terminal device detects that the second bit information in the implicit system information indicates the transmission parameter configuration of the corresponding serving cell, the second access strategy of the corresponding serving cell is determined. The following will describe it in detail with reference to specific examples.
Example five: when the terminal device detects that the second bit information in the implicit system information indicates that the transmission parameter configuration of the broadcast and/or control channel of the corresponding service cell is the same as the transmission parameter configuration of the primary synchronization signal, the transmission parameter configuration of the broadcast and/or control channel is calculated, and then the broadcast and/or control channel is received and demodulated through the calculated transmission parameter configuration of the broadcast and/or control channel. That is, the network device predefines 1-bit system information by the location information of the primary synchronization signal and/or the secondary synchronization signal to indicate: whether the same parameters (such as subcarrier spacing) as the primary synchronization signal and/or the secondary synchronization signal are used in the data region and/or the Physical Broadcast Channel (PBCH) in the present frequency band. The terminal equipment acquires the preset information of the system through the position information of the main synchronizing signal and/or the auxiliary synchronizing signal, and if the data and the synchronizing signal adopt different subcarrier intervals, the terminal equipment further judges the subcarrier intervals of the data area according to the current frequency point position (for example, in a 5G system, two subcarrier interval parameters are respectively adopted by a >6G system and a <6G system). The terminal equipment obtains the parameter information of the data area and the PBCH in advance and prepares for channel estimation and data demodulation.
Example six: and when the terminal equipment detects that the second bit information in the implicit system information indicates the beam number corresponding to the serving cell, the terminal equipment performs receiving beam training according to the corresponding beam number and receives broadcast and/or control channel data through the beam with the best performance. For example: the base station is a multi-Panel multi-beam capability base station, and the network equipment predefines 2 bits or multi-bit system information through the position information of the primary synchronization signal and/or the secondary synchronization signal to indicate that: the wave speed number of the primary synchronization signal and/or the secondary synchronization signal. The terminal equipment acquires the preset information of the system through the position information of the main synchronizing signal and/or the auxiliary synchronizing signal, and the terminal equipment rapidly completes the beam receiving training of the terminal equipment according to the wave speed number of the main synchronizing signal and/or the auxiliary synchronizing signal and the condition of receiving the main synchronizing signal and/or the auxiliary synchronizing signal, so that the terminal equipment is ready for subsequent broadcasting and data receiving.
Example seven: when the terminal device detects that the second bit information in the implicit system information indicates whether the corresponding serving cell supports Long Term Evolution (LTE) access, a corresponding access strategy or a switching strategy is determined. The network device predefines 1-bit system information through the position information of the primary synchronization signal and/or the secondary synchronization signal to indicate whether the local cell base station supports Long Term Evolution (LTE) access. The terminal equipment acquires the preset information of the system through the position information of the primary synchronization signal and/or the secondary synchronization signal, and a potential optimization space is reserved in cell selection search and cell residence for the terminal which supports the LTE and 5G systems.
Example eight: when the terminal device detects that the second bit information in the implicit system information indicates the downlink system bandwidth of the corresponding service cell, the transmission parameter configuration of the broadcast and/or control channel is calculated according to the downlink system bandwidth, and then the broadcast and/or control channel is received and demodulated through the calculated transmission parameter configuration of the broadcast and/or control channel. For example: the network device predefines 3-bit system information through the position information of the primary synchronization signal and/or the secondary synchronization signal to indicate the downlink system bandwidth of the frequency band. The terminal equipment acquires the preset information of the system through the position information of the main synchronizing signal and/or the auxiliary synchronizing signal so as to save information transmission of the PBCH system and prepare for subsequent broadcasting and data receiving.
According to the embodiment of the invention, through the design of configuration mapping of the primary synchronization signal and the secondary synchronization signal, extra hidden system information is obtained in the initial cell search process, and a space is provided for terminal optimization access network and network regulation initial access. In addition, the additional hidden system information is obtained through the position information of the main synchronizing signal and/or the auxiliary synchronizing signal, so that the signaling overhead of the system information can be reduced, the network transmission resource can be saved, and an optimization strategy can be further provided for the terminal equipment to access the network and the network to regulate and control the initial access.
