Background
The base station energy conservation is used as one of means for saving the expenditure of operators and realizing low carbon and high efficiency in the wireless communication field, and the consistent support of operators and equipment providers is obtained. From the time domain perspective, due to the existence of periodic broadcast signals, such as Synchronization Signal Blocks (SSBs), system information and scheduling information thereof, these symbols cannot realize sleep of the base station, and how to perform transmission optimization of such signals will be considered in the research of the enhancement technology, so that the sleep time of the base station is increased. For example, the transmission period of the SSB and the system information block (SIB, system Information Block) is increased, so that the number of time slots and the number of symbols which can be put into sleep by the base station are increased, and the energy consumption of the base station is saved.
In a single carrier scenario, since the terminal can only realize initial access through a single carrier, after the transmission period of the SSB and the system information is increased, the terminal does not know on which SSB transmission occasion the SSB will be sent, so that detection will be attempted at each transmission occasion, and the energy consumption is high for the terminal.

The embodiment of the invention provides a transmission indication method. Fig. 1 is a flowchart of a transmission indicating method according to an embodiment of the present invention; as shown in fig. 1, the method includes:
step 101: the network equipment sends a downlink signal containing a synchronous signal; wherein the downstream signal is used to determine at least one of:
transmission timing or transmission period of PBCH;
Transmission opportunity or transmission period of type 0-PDCCH;
the transmission timing or transmission period of the system information.
In this embodiment, the network device sends a downlink signal including a synchronization signal, which may be considered that the network device sends a downlink signal or a first signal, where the downlink signal or the first signal includes the synchronization signal. Taking the example that the synchronization signal includes the PSS, the network device transmits a downlink signal including the PSS, or the network device transmits a downlink signal or a first signal, where the downlink signal or the first signal includes the PSS.
In this embodiment, as an example, the synchronization signal may include multiple types, and transmission characteristics of the different types of synchronization signals may be different, for example, transmission patterns (patterns) or transmission periods of the different types of synchronization signals are different, and the network device may indicate a transmission timing or transmission period of the PBCH, a transmission timing or transmission period of the type 0-PDCCH, a transmission timing or transmission period of the system information, and the like through the transmission characteristics of the different types of synchronization signals. Note that, when the downlink signal is used to indicate the transmission timing or the transmission period of the PBCH, the synchronization signal included in the downlink signal does not include the PBCH, that is, the transmission timing or the transmission period of the PBCH may be indicated by the transmission characteristics of other types of synchronization signals except the PBCH.
In some alternative embodiments, the network device sends a downlink signal including a synchronization signal, including at least one of:
the network equipment transmits a downlink signal containing a PSS at least one first transmission opportunity in a first period;
the network device transmits a downlink signal including PSS and SSS at a second transmission opportunity in a second period.
Optionally, the downlink signal is used for determining a transmission opportunity or a transmission period of the PBCH; wherein, the PBCH is transmitted together with the PSS and the SSS on a third transmission occasion in a third period; the second period is N times of the first period, N is a positive integer greater than or equal to 1, the third period is M times of the second period, and M is a positive integer greater than or equal to 1.
In the conventional technical scheme, a Synchronization Signal Block (SSB) includes PSS, SSS, and PBCH. Typically, the transmission period of SSB is 20 milliseconds (ms). And by increasing the transmission period of the synchronous signal, the number of time slots, the number of symbols and the like of the base station which can go to sleep are increased, so that the effect of saving the energy consumption of the base station is achieved. Therefore, in this embodiment, the above-mentioned effects can be achieved by increasing the period of the synchronization signal. In addition, the transmission periods of the synchronization signals of different types are different, so that the indication of the transmission time or transmission period of the PBCH, the transmission time or transmission period of the type 0-PDCCH, the transmission time or transmission period of the system information and the like is realized.
Except for the transmission period, SSBs have a certain time domain distribution in each period, and all SSB positions in the same period are limited to 5 ms. This structure ensures that the terminal can complete measurement of all SSBs within 5ms without opening the measurement window multiple times in one period, which is advantageous for terminal measurement and power consumption saving. Meanwhile, in 5G NR, for macro station coverage scenarios, the base station typically needs to configure a semi-static frame structure. In the semi-static frame structure, the downlink resource is generally configured in the first half of the downlink-uplink conversion period, and the SSB in the period is centrally placed in 5ms, which is beneficial to placing the SSB in the downlink resource configured in the semi-static frame structure. Referring to fig. 2, a diagram of a slot distribution including SSBs in a low-band 5ms window is shown, wherein a non-blank portion represents a slot having SSB transmissions.
The specific time domain distribution position of SSB in a 5ms time window is related to SSB subcarrier spacing and frequency band. Five SSB arrangement modes of Case A, case B, case C, case D and Case E are given in the current protocol, wherein Case A/B/C aims at a frequency band below 6GHz, and Case D/E aims at high-frequency millimeter waves.
The specific locations of SSBs for various arrangements are as follows:
Case a: for the 15kHz SSB subcarrier spacing scenario. The first symbol of SSB has a position number {2,8} +14×n. For the corresponding L max A frequency band of=4, n=0, 1, i.e. occupies only 2 slots (slots); for the corresponding L max A frequency band of 8, n=0, 1,2,3, occupies 4 slots. FIG. 3a shows that SSB subcarrier spacing employs 15kHz and L max When=4, SSB is located within the 5ms window.
Case B: for a 30kHz SSB subcarrier spacing. The first symbol position number of SSB is {4,8,16,20} +28×n. For the corresponding L max Frequency band of=4, n=0; for the corresponding L max Frequency band of=8, n=0, 1. FIG. 3b shows that SSB subcarrier spacing employs 30kHz and L max When=8, case B SSB is located within the 5ms window.
Case C: for a 30kHz subcarrier spacing. The first symbol position number of SSB is {2,8} +14×n. For the corresponding L max Frequency band of=4, n=0, 1; for the corresponding L max Frequency band of=8, n=0, 1,2,3. FIG. 3b shows the use of 30kHz SSB subcarrier spacing and L max When=8, case C SSB is located within the 5ms window.
Case D: for the scenario where the SSB subcarrier spacing is 120 kHz. The first symbol position of SSB is {4,8,16,20} +28×n, for high frequency bands above 6GHz (L max ＝64)，n＝0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18。
Case E: for the scenario where the SSB subcarrier spacing is 240kHz, the first symbol position of SSB is {8,12,16,20,32,36,40,44} +56 n, n= 0,1,2,3,5,6,7,8 for high frequency bands above 6 GHz.
Notably, when a 30kHz SSB subcarrier spacing is employed for the frequency band below 6GHz, there are two placement modes for SSBs: case B, case C (shown in fig. 3B).
It can be seen here that each SSB has a certain starting symbol position, and 4 symbols are transmitted consecutively from the starting symbol, carrying SSBs, and the transmission opportunity of each 4-symbol SSB is referred to herein as a transmission opportunity. It can be seen that a transmission opportunity may contain a plurality of symbols, located within a slot. These arrangements actually give transmission opportunities for different SSB indexes within a period. For the same SSB index, it repeats transmission on its corresponding transmission occasion according to the SSB period, such as 20ms (or other value).
In this embodiment, the synchronization signal included in the downlink signal includes PSS, and/or includes PSS and SSS; wherein only the PSS is transmitted at least one first transmission occasion in a first period, and the PSS and the SSS are commonly transmitted at a second transmission occasion in a second period, that is, the transmission period of the PSS and the transmission period of the SSS are different, and the PSS is commonly transmitted while the SSS is transmitted. Referring to fig. 4, fig. 4 (a) shows the transmission of SSB in the conventional scheme, with a transmission period of 20ms. Fig. 4 (b) shows the downlink signal transmission in this embodiment, in this example, PSS is still transmitted according to the conventional 20ms transmission period, but SSS transmission period is 40ms, i.e. N is equal to 2, i.e. every other PSS, and SSS and PSS accompanying transmission will occur. Of course, the above is merely an example, and in other embodiments, N may be another value, which is not limited in this embodiment.
In this embodiment, the PBCH is only co-transmitted with the PSS and SSS, so that it is possible to transmit the PBCH only at the transmission timing of the co-transmission of the PSS and SSS. Referring to fig. 4, the transmission period of the PBCH is 80ms, that is, M is equal to 2, that is, every transmission opportunity of the common transmission of PSS and SSS, the concomitant transmission of the PBCH with PSS and SSS occurs. Of course, the above is merely an example, and M may take other values in other embodiments, which are not limited in this embodiment. The PBCH is sent together with the PSS and the SSS, which may specifically mean that the PBCH, the PSS and the SSS are sent simultaneously on a transmission opportunity (e.g., a third transmission opportunity) of the SSB, that is, the PBCH, the PSS and the SSS are sent simultaneously on consecutive 4 symbols corresponding to the transmission opportunity (e.g., the third transmission opportunity) of the SSB.
Inspection of terminalsIn terms of measurement, the terminal will detect the PSS on the synchronization grid first, and the terminal decodes the PSS signal to obtain a part of cell IDThe value is {0,1,2}. After demodulation of the PSS, the terminal will continue to try to decode SSS with 336 values corresponding to 336 Gold sequences obtained by modulo-two addition of two 127 long m-sequences, thus obtaining part of cell ID->The value range is {0,1, … 335}; finally according to the formula->A complete cell ID is obtained. And then demodulates the PBCH to obtain necessary cell information, etc.
In this embodiment, after the terminal detects the PSS, it is possible to detect the SSS at the same transmission timing (occalation), or it is possible to detect no SSS, and the terminal may determine based on this, and then the detection of the PBCH only needs to be performed at the moment when the PSS and the SSS occur simultaneously. Referring to fig. 4, for example, UE1 searches PSS at a certain transmission timing, after acquiring PSS, and does not acquire SSS, UE1 will go to the next transmission timing (transmission period of 20 ms) to acquire SSS and attempt to detect PBCH, and after detecting PSS and SSS, and does not acquire PBCH, UE will only continue to attempt to acquire PBCH at intervals of 40ms, and will not detect at PSS-only transmission timing, thereby saving terminal power consumption. For another example, for UE2, PSS and SSS are detected at a certain transmission timing, but no PBCH is detected, the terminal skips the next detection timing, and detects the PBCH at intervals of one timing, so as to achieve terminal energy saving; or the detection is performed at the next detection time, possibly only the PSS is detected, further the detection is performed at the next detection time, the PBCH is detected, and the PSS and the SSS are detected at the same time, so that the transmission period of the PSS and the SSS is defined to be 40ms.
In some alternative embodiments, the PBCH is used to indicate a transmission occasion of the type0-PDCCH and/or a transmission occasion of the system information.
In this embodiment, the type0-PDCCH (type 0-PDCCH) is detected in the search space corresponding to the transmission timing of the PBCH, that is, the transmission timing of the PBCH is associated with or corresponds to the transmission timing or transmission period of the type0-PDCCH, that is, the downlink signal including the synchronization signal in this embodiment can implicitly indicate the type0-PDCCH. The type0-PDCCH is used for scheduling system information, that is, the downlink signal containing the synchronization signal in this embodiment can also implicitly indicate the transmission timing or transmission period of the system information. The system message may be, for example, a system information block (SIB, system Information Block), such as SIB1, among others.
In some optional embodiments of the invention, the downlink signal comprises PSS, SSS and PBCH co-transmitted in a fourth period, and the PBCH in the downlink signal is used to indicate at least one of:
transmission opportunity or transmission period of type 0-PDCCH;
the transmission timing or transmission period of the system information.
In this embodiment, the fourth period may be a transmission period of SSB in the conventional technical scheme, for example, 20ms. The present embodiment refers to transmitting downlink signals including PSS, SSS and PBCH, that is, SSB, using a conventional 20ms transmission period. In this embodiment, at least one of the following may be indicated by a bit in the PBCH: transmission opportunity or transmission period of type 0-PDCCH; the transmission timing or transmission period of the system information. By way of example, by indicating a transmission period of type0-PDCCH and/or system information with a limited bit in the PBCH, a conventional transmission period is 20ms, and a transmission period of type0-PDCCH and/or system information may be 40ms, 80ms, 160ms, etc., 2 bits are required for indication. Of course, the transmission period of the type0 PDCCH and/or the system information is not limited to the above example, but may be another value, which is not limited in this embodiment.
The jointly transmitted PSS, SSS, and PBCH may specifically refer to simultaneously transmitting the PBCH, PSS, and SSS on the transmission opportunity of the SSB, that is, simultaneously transmitting the PBCH, PSS, and SSS on consecutive 4 symbols corresponding to the transmission opportunity of the SSB.
In some optional embodiments, reserved bits of MIB information in the PBCH and/or bits related to slots in the PBCH are used to indicate at least one of:
transmission opportunity or transmission period of type 0-PDCCH;
the transmission timing or transmission period of the system information.
The PBCH channel carries information of 24 bits (bits) of a higher layer and 8 bits of information of a physical layer, wherein the 24 bits of the higher layer have 1 reserved bit. The reserved bits of MIB information in the PBCH are reserved bits of a higher layer. Of the 8 bits of the physical layer, 4 bits are the four Least Significant Bits (LSBs) of the system frame number, 2 bits are the system field indication, and 3 bits are the three Most Significant Bits (MSBs) of the SSB index (SSB index). For the case of maximum beam number lmax=64, this information indicates the 3-bit MSB of SSB index. For the frequency band below 6GHz, only 8 beams are supported at maximum, SSB index is completely determined by demodulation reference signals (DMRS, demodulation Reference Signal) of PBCH, therefore, in the low frequency below 6GHz, 1bit of the 3 bits is used, the offset of subcarrier levels between SSB and SIB1 control channels is indicated in combination with SSB-subbrierOffset fields, and the other 2 bits are reserved information; the bit related to the time slot in the PBCH is the bit of the physical layer in the above scenario. That is, the PBCH carries the MIB information of the higher layer, and generates 8 bits of timing related bits (timing related PBCH payload bits), and the last two bits of 1 reserved bit and/or the bits related to the slot (8 bits) in the MIB may be used as reserved two bits to indicate the transmission period or transmission opportunity of the type 0-PDCCH and/or SIB1 when L is not equal to 64. For example 00 means a default 20ms period, 01 means 40ms,10 means 80ms,11 means 160ms, etc. Indicating a transmission opportunity includes indicating at what periodic intervals to transmit in a period, or indicating intervals at which transmission times occur, or the positions of slots in which they occur, etc.
In some alternative embodiments of the invention, the method further comprises: the network device transmits the system information based on the transmission timing or transmission period of the system information, and/or transmits the type 0-PDCCH based on the transmission timing or transmission period of the type 0-PDCCH.
Optionally, the frame identifier of the radio frame used for transmitting the system information and the transmission period of the system information satisfy a convention relationship, and/or the frame identifier of the radio frame used for transmitting the type 0-PDCCH and the transmission period of the type 0-PDCCH satisfy a convention relationship.
In this embodiment, if the transmission period of the system information or the transmission type 0-PDCCH (i.e. the control channel for scheduling the system information) is indicated through the PBCH, the transmission timing in the transmission period needs to be determined. For example, system information in P rep Transmission is performed in a period of 80ms, and then a transmission opportunity of system information occurs every 4 SSBs, and at which of the 4 transmission opportunities the system information occurs needs to be agreed in advance. In this embodiment, for example, SFN x 10mod prep=0, or SFN mod (P rep A radio frame of/10) =0 as a transmission timing for transmitting system information; if P rep When the unit of (a) is 10ms, a radio frame of SFN mod Prep=0 is agreed as a transmission opportunity for transmitting system information; wherein SFN represents a system frame number (System Frame Number), frame timing corresponding to every SFN is 10ms, P rep Representing the transmission period of the system information. In this way, the terminal can obtain the frame timing of 10ms after receiving the PBCH, can know the transmission period of the current system information (such as SIB 1) according to the 2 bit indication in the PBCH, determine the transmission time of the system information (such as SIB 1) according to the agreed relation, and only detect the system information (such as SIB 1) at the transmission time. Of course, other agreed relationships may be used to determine the transmission timing, which is not limited in this embodiment. Similarly, the determination manner of the transmission opportunity of the type0-PDCCH refers to the determination manner of the transmission opportunity of the system information, and is not described herein.
Illustratively, referring to fig. 5, SSBs are transmitted at a transmission period of 20 ms. The UE1 detects the PBCH to obtain frame timing of 10ms, and can determine that the transmission period of the SIB1 is 80ms through bit indication in the PBCH, and then can determine the transmission opportunity of the SIB1 according to the agreed relation, and further read the SIB1 and the scheduling PDCCH (i.e. type 0-PDCCH) at the corresponding transmission opportunity. Wherein, the scheduling PDCCH (i.e. type 0-PDCCH) is used for scheduling SIB, namely, the reading of SIB is realized by reading the scheduling PDCCH (i.e. type 0-PDCCH).
In some alternative embodiments of the invention, the method further comprises: the network equipment receives a first signal sent by a terminal, wherein the first signal is used for requesting or triggering the network equipment to send system information and/or type0-PDCCH in a fourth period; the network device transmits system information and/or type0-PDCCH at a fourth transmission occasion with a fourth period.
In this embodiment, in the case of using the transmission timing or transmission period of the PBCH indication type0-PDCCH and/or the transmission timing or transmission period of the system information described above, the transmission period of the type0-PDCCH and/or the transmission period of the system information may be longer, more than the conventional 20ms. If the terminal has higher requirement on the time delay, the terminal can also actively initiate a request, request or trigger the network device to send the system information in the fourth period (20 ms). The first signal may use a preamble (preamble) similar to a physical random access channel (PRACH, physical Random Access Channel), for example, i.e. the terminal sends system information and/or type0-PDCCH in a fourth period by sending a preamble request or triggering the network device. Further, after receiving the first signal, the network device transmits system information and/or type0-PDCCH at a fourth transmission opportunity in a fourth period (20 ms).
Referring to fig. 6, when the UE detects the PBCH in the SSB and obtains frame timing of 10ms and determines that the transmission period of SIB1 or type0-PDCCH is 80ms through bit indication in the PBCH, the UE may determine the transmission timing of SIB1 or type0-PDCCH according to the agreed relation, and further read SIB1 and schedule PDCCH (i.e. type 0-PDCCH) at the corresponding transmission timing. The UE may send a first signal requesting that SIB1 be obtained in advance. The advance refers to SIB1 or type0-PDCCH originally transmitted according to 80ms, after the base station receives the first signal, the base station returns to transmitting SIB1 and information of scheduling PDCCH thereof according to a time-frequency resource location determined by SSB corresponding to the next 20ms period according to a conventional 20ms (or other agreed period). According to the PDCCH-ConfigSIB 1-8 bit in the PBCH in the existing flow SSB, the method is used for indicating the time-frequency resource position of a control resource set (CORESET) for scheduling SIB1 messages and the parameters of the corresponding type0-PDCCH search space; therefore, when SSB is transmitted according to the 20ms period, the period of the control information indicated by the corresponding PBCH for scheduling SIB1 message is also recovered to 20ms from the larger period, the information of the type0-PDCCH and the corresponding CORESET is indicated by the PBCH, the detected time-frequency resource position is determined, and then the detected time-frequency position of SIB1 is determined through the PDCCH detected in the type0-PDCCH search space, so as to obtain SIB1. While not every PBCH is followed by SIB1 or type0-PDCCH in the same period when SIB1 or type0-PDCCH is transmitted in 80 ms. The UE receives SIB1 and scheduling PDCCH at the next SSB transmission time, acquires random access information, and initiates a random access flow.
In some alternative embodiments, the network device receives a first signal sent by a terminal, including: the network device receives the first signal in the last subframe of the radio frame in which the fifth transmission opportunity of the synchronous signal is sent.
In this embodiment, since the frame structure period 10ms is necessarily repeated once, it is possible to transmit at the last subframe of the radio frame where the timing of receiving the SSB is located.
Based on the above embodiment, the embodiment of the present invention further provides a transmission indication method. Fig. 7 is a second flowchart of a transmission indication method according to an embodiment of the present invention; as shown in fig. 7, the method includes:
step 201: the terminal receives a downlink signal containing a synchronous signal; determining at least one of the following based on the downstream signal: transmission timing or transmission period of PBCH; transmission opportunity or transmission period of type 0-PDCCH; the transmission timing or transmission period of the system information.
In this embodiment, as an example, the synchronization signal may include multiple types, and transmission characteristics of the different types of synchronization signals may be different, for example, transmission patterns (patterns) or transmission periods of the different types of synchronization signals are different, and the network device may indicate a transmission timing or transmission period of the PBCH, a transmission timing or transmission period of the type 0-PDCCH, a transmission timing or transmission period of the system information, and the like through the transmission characteristics of the different types of synchronization signals. Note that, when the downlink signal is used to determine the transmission timing or the transmission period of the PBCH, the synchronization signal included in the downlink signal does not include the PBCH, that is, the transmission timing or the transmission period of the PBCH may be indicated by the transmission characteristics of other types of synchronization signals except the PBCH. The terminal may determine at least one of the following according to the type of the synchronization signal in the received downlink signal and its transmission characteristics: transmission timing or transmission period of PBCH; transmission opportunity or transmission period of type 0-PDCCH; the transmission timing or transmission period of the system information.
In some alternative embodiments, the terminal receives a downlink signal including a synchronization signal, including at least one of:
the terminal receives a downlink signal containing a PSS at least one first transmission opportunity in a first period;
the terminal receives the downlink signal including the PSS and the SSS at a second transmission opportunity in a second period.
Optionally, the PBCH is transmitted together with the PSS and the SSS on a third transmission occasion in a third period; the second period is N times of the first period, N is a positive integer greater than or equal to 1, the third period is M times of the second period, and M is a positive integer greater than or equal to 1.
In this embodiment, the synchronization signal included in the downlink signal includes PSS, and/or includes PSS and SSS; wherein only the PSS is transmitted at least one first transmission occasion in a first period, and the PSS and the SSS are commonly transmitted at a second transmission occasion in a second period, that is, the transmission period of the PSS and the transmission period of the SSS are different, and the PSS is commonly transmitted while the SSS is transmitted.
In this embodiment, the PBCH is only co-transmitted with the PSS and SSS, so that it is possible to transmit the PBCH only at the transmission timing of the co-transmission of the PSS and SSS. Therefore, after the terminal detects the PSS, it is possible to detect the SSS on the same transmission timing (occalation), or it is possible to detect no SSS, and the terminal may determine that the subsequent PBCH detection only needs to be detected at the moment when the PSS and the SSS occur simultaneously, so as to determine the transmission period or the transmission timing of the PBCH. Referring to fig. 4, for example, UE1 searches PSS at a certain transmission timing, after acquiring PSS, and does not acquire SSS, UE1 will go to the next transmission timing (transmission period of 20 ms) to acquire SSS and attempt to detect PBCH, and after detecting PSS and SSS, and does not acquire PBCH, UE will only continue to attempt to acquire PBCH at intervals of 40ms (i.e. interval of second period), but will not detect at the transmission timing of PSS only, thereby saving terminal power consumption. For another example, for UE2, PSS and SSS are detected at a certain transmission timing, but no PBCH is detected, the terminal skips the next detection timing, and detects the PBCH at intervals of one timing, so as to achieve terminal energy saving; or the detection is performed at the next detection time, possibly only the PSS is detected, further the detection is performed at the next detection time, the PBCH is detected, and the PSS and the SSS are detected at the same time, so that the transmission period of the PSS and the SSS is defined to be 40ms.
In some alternative embodiments, the PBCH is used to indicate a transmission occasion of the type0-PDCCH and/or a transmission occasion of the system information.
In this embodiment, the type0-PDCCH (type 0-PDCCH) is detected in the search space corresponding to the transmission timing of the PBCH, that is, the transmission timing of the PBCH is associated with or corresponds to the transmission timing or transmission period of the type0-PDCCH, that is, the downlink signal including the synchronization signal in this embodiment can implicitly indicate the type0-PDCCH. The type0-PDCCH is used for scheduling system information, that is, the downlink signal containing the synchronization signal in this embodiment can also implicitly indicate the transmission timing or transmission period of the system information. The system message may be, for example, a system information block (SIB, system Information Block), such as SIB1, among others.
In some optional embodiments of the invention, the downlink signal comprises PSS, SSS and PBCH co-transmitted in a fourth period, and the PBCH in the downlink signal is used to indicate at least one of:
transmission opportunity or transmission period of type 0-PDCCH;
the transmission timing or transmission period of the system information.
In this embodiment, the fourth period may be a transmission period of SSB in the conventional technical scheme, for example, 20ms. The present embodiment refers to transmitting downlink signals including PSS, SSS and PBCH, that is, SSB, using a conventional 20ms transmission period. In this embodiment, at least one of the following may be indicated by a bit in the PBCH: transmission opportunity or transmission period of type 0-PDCCH; the transmission timing or transmission period of the system information. By way of example, by indicating a transmission period of type0-PDCCH and/or system information with a limited bit in the PBCH, a conventional transmission period is 20ms, and a transmission period of type0-PDCCH and/or system information may be 40ms, 80ms, 160ms, etc., 2 bits are required for indication. Of course, the transmission period of the type0 PDCCH and/or the system information is not limited to the above example, but may be another value, which is not limited in this embodiment.

In some alternative embodiments of the invention, the method further comprises: the terminal receives the system information based on the transmission timing or transmission period of the system information and/or receives the type 0-PDCCH based on the transmission timing or transmission period of the type 0-PDCCH.
Optionally, the frame identifier of the radio frame used for transmitting the system information and the transmission period of the system information satisfy a convention relationship, and/or the frame identifier of the radio frame used for transmitting the type 0-PDCCH and the transmission period of the type 0-PDCCH satisfy a convention relationship.
In this embodiment, if the transmission period of the system information or the transmission type 0-PDCCH (i.e. the control channel for scheduling the system information) is indicated through the PBCH, the transmission timing in the transmission period needs to be determined. For example, system information in P rep Transmission is performed in 80ms period, then every 4 SSBs are transmitted at regular intervalsWhen a transmission opportunity of the system information occurs, which of the 4 transmission opportunities the system information occurs on needs to be contracted in advance. In this embodiment, for example, SFN x 10mod P may be agreed rep =0, or SFN mod (P rep A radio frame of/10) =0 as a transmission timing for transmitting system information; if P rep When the unit of (a) is 10ms, a radio frame of SFN mod Prep=0 is agreed as a transmission opportunity for transmitting system information; wherein SFN represents a system frame number (System Frame Number), frame timing corresponding to every SFN is 10ms, P rep Representing the transmission period of the system information. In this way, the terminal user can obtain the frame timing of 10ms after receiving the PBCH, can know the transmission period of the current system information (such as SIB 1) according to the 2 bit indication in the PBCH, determine the transmission time of the system information (such as SIB 1) according to the agreed relation, and only detect the system information (such as SIB 1) at the transmission time. Of course, other agreed relationships may be used to determine the transmission timing, which is not limited in this embodiment.
In some alternative embodiments of the invention, the method further comprises: the terminal sends a first signal, wherein the first signal is used for requesting or triggering the network equipment to send system information and/or type 0-PDCCH in a fourth period; the terminal receives system information and/or type 0-PDCCH at a fourth transmission opportunity in a fourth period.
In this embodiment, in the case of using the transmission timing or transmission period of the PBCH indication type 0-PDCCH and/or the transmission timing or transmission period of the system information described above, the transmission period of the type 0-PDCCH and/or the transmission period of the system information may be longer, more than the conventional 20ms. If the terminal has higher requirement on the time delay, the terminal can also actively initiate a request, request or trigger the network device to send the system information in the fourth period (20 ms). The first signal may use a preamble (preamble) similar to a physical random access channel (PRACH, physical Random Access Channel), for example, i.e. the terminal sends system information and/or type 0-PDCCH in a fourth period by sending a preamble request or triggering the network device. Further, after receiving the first signal, the network device transmits system information and/or type 0-PDCCH at a fourth transmission opportunity in a fourth period (20 ms).
The terminal transmits a first signal, including: and the terminal sends the first signal in the last subframe of the radio frame where the fifth transmission time of the synchronous signal is received.
