5, SCS=240KHz: the index of the primary sign of candidate SS/PBCH block include: 8,12,16,20,32, 36,40,44}+56*n.When carrier frequency is greater than 6GHz, n=0,1,2,3,5,6,7,8.

Wherein, ascending order number is 0 to L- to the candidate SS/PBCH block in SS burst set window in time 1；L is positive integer, and value can be equal to 4 or be greater than for 4 (but being no more than 64).These numbers are also known as time index (time index).Regulation carries the time index (time index) in SS/PBCH block in NR, is used to refer to SS/PBCH Time location of the block in SS burst set window.

As can be seen that for specific SCS (such as SCS=15KHz), to being used in SS burst set window in NR It is provided in the preset time position (i.e. candidate SS/PBCH block) for sending SS/PBCH block.In other words, institute Some SS/PBCH block can only be sent on position (slot/ symbol) at a fixed time, the time in SS/PBCH block Index (time index) can be used to refer to serial number of the current SS/PBCH block in SS burst set window.This Sample, in NR system, when terminal detects a SS/PBCH block, terminal can be according in the SS/PBCH block The time index (time index) that PBCH is carried determines that the SS/PBCH block is corresponding in SS burst set window Which preset time position, and then determine system timing information occupied symbol is (i.e. in SS burst set window PSS symbol, SSS symbol in the SS/PBCH block).In addition, terminal can be taken according to PBCH in the SS/PBCH block Field instruction information (half frame indication) of band determines SS burst set locating for the SS/PBCH block Window is the preceding 5ms or rear 5ms positioned at 10ms radio frames (radio frame).In this way, terminal can have correctly received net The system timing information that network equipment (such as network equipment (such as gNB)) is sent is completed synchronous between terminal and the network equipment.

Illustrate the resource impact of the system information in LTE, NR below.

In LTE, system information includes host system message block (MIB) and several system information blocks (system Information block, SIB).As shown in fig. 6, the time location that MIB maps in the time window of 80ms remains unchanged, It is repeatedly transmitted in 80ms 4 times, and occupies the frequency domain resource of channel center's bandwidth both sides totally 72 subcarriers.MIB carries use Resource indication information (such as resource location and resource size of the essential information needed for user carries out random access and SIB 1 Deng).SIB 1 carries the scheduling information of a part of system information and other SIB (such as SIB2-SIB13).SIB 1 in LTE As shown with 7, the time location that SIB 1 maps in the time window of 80ms remains unchanged sending method, and hair is repeated in 80ms It send four times, being located at length by sending time position is the 5th subframe in 10ms radio frames.

In NR, system information includes host system message block (MIB), remaining minimum system information (RMSI) and other systems letter It ceases (OSI).Wherein, MIB is carried in Physical Broadcast Channel PBCH, and RMSI is carried on RMSI Physical Downlink Shared Channel In (physical downlink shared channel, PDSCH).RMSI is similar to the SIB 1 in LTE, the difference of the two It is, it is fixed for sending the time location of SIB 1, and NR is in order to improve the flexibility of system call, the money of RMSI PDSCH Source position and resource size be it is variable, indicated by RMSICORESET.As shown in figure 8, the SS/PBCH block and SS/PBCH There are 3 kinds of resource mapping methods by the corresponding RMSI CORESET of block, RMSI PDSCH.RMSI CORESETR/RMSI PDSCH and SS/PBCH block can be time division multiplexing (time division multiplexing) or frequency division multiplexing The mode multiplexed resource of (frequency division multiplexing).The resource indication information of RMSI CORESET is held It is loaded in PBCH, shares 8 bits.

It is found that after LBT is listened to successfully, the network equipment can be sent the LBT mechanism with reference to shown in Fig. 3 A-3B with busy channel Downlink data, such as SS/PBCH block.LBT listens to maximum channel holding time (the max channel successfully allowed Occupy time, MCOT) it is limited, such as MCOT is 10ms.If some of the network equipment after LBT is listened to successfully (a little) time slot does not send downlink signal, then will lead to channel idle, may be competed by other equipment to channel, to lose letter Road.Here, it loses channel and refers to that the network equipment for being successfully accessed channel loses channel access power, need to re-start LBT Channel could be accessed again after success.RMSI PDSCH resources employment methods in NR cannot be guaranteed that SS/PBCH block is right with its The RMSI PDSCH answered is mapped on continuous time resource, because the resource location of the RMSI PDSCH in NR is very flexibly 's.In that way it is possible to which the network equipment after causing LBT to listen to successfully is after sending SS/PBCH block, due to there is channel idle And channel access power is lost, to need that the corresponding RMSI of SS/PBCH block could be sent after LBT is listened to successfully again PDSCH.In other words, system information disposably cannot completely be sent, and reduce the efficiency of terminal equipment access system.This In, disposably refer to that a LBT listens to success.

As can be seen that the flexible RMSI PDSCH resources employment methods designed in NR are not suitable for NR-U system.

In addition, Fig. 9 shows existing a kind of SS/PBCH block and RMSIPDSCH joint sending method in NR-U.

As shown in figure 9, being 20MHz in system bandwidth, subcarrier spacing is under the scene of 60KHz, and 20MHz channel includes 24 A available RB.SS/PBCH block occupies symbol 2-5.Wherein, on symbol 2, SS/PBCH block is occupied on frequency domain 12 RB.On 3 symbols below, SS/PBCH block occupies 20 RB on frequency domain.It requires (to send out to meet OCB The 80% of 20MHz channel width will be occupied by sending when data), the subcarrier two that NR-U equipment can be occupied in SS/PBCH block Side filling RMSI PDSCH makes downlink data take 24 RB.In other words, on symbol 2-5, SS/PBCH block and RMSIPDSCH can use frequency division multiplexing resource mapping method.

It should be understood that in frequency division multiplexing resource mapping method shown in Fig. 9, SS/PBCH block and RMSI PDSCH is mapped on identical symbol, it can be ensured that the two is sent simultaneously.But this resource mapping method can carry RMSI PDSCH bit number be it is very limited, about tens bits far can not solve about 1000 bits or more The resource impact problem of RMSI PDSCH payload (payload).

The application will mainly consider in SS/PBCH block RMSI PDSCH corresponding with its using time-multiplexed resource When mapping mode, it should how to carry out resource impact to them to avoid channel is lost.In this regard, this application provides in NR-U system The technical solution of SS/PBCH block and its corresponding RMSI PDSCH is sent in system.

The main inventive thought of the application one side can include: in time location and the transmission for sending SS/PBCH block Blank character (i.e. non-bearing downlink signal is not present between the time location of the corresponding RMSI PDSCH of the SS/PBCH block Symbol), to avoid channel loss, it is ensured that system information is completely sent after a LBT is listened to successfully.Its major programme can It is as follows:

Scheme one: sending the time location of the corresponding RMSI PDSCH of SS/PBCH block and sends the SS/PBCH The time location continuous adjacent of block, wherein carry MIB in SS/PBCH block, carry RMSI in RMSI PDSCH. It is therefore not required to which RMSI CORESET indicates the resource distribution of RMSI PDSCH, instruction information is carried in SS/PBCH block To indicate the resource distribution of RMSI PDSCH.

Scheme two: it sends the time location of SS/PBCH block, send the corresponding RMSI of SS/PBCH block The time location of CORESET, the time location continuous adjacent for sending the corresponding RMSI PDSCH of the SS/PBCH block, wherein MIB is carried in SS/PBCH block, carries RMSI in RMSI PDSCH.According to the regulation in NR, RMSI CORESET's Resource distribution is indicated that the resource distribution of RMSI PDSCH is indicated by RMSI CORESET by the PBCH in SS/PBCH block.

Under the scene of unauthorized frequency range, above two scheme can realize that system information is disposably completely sent out It send, the network equipment is avoided to lose channel during sending system information, improve the initial access efficiency of terminal device.Difference It is, scheme one does not need RMSI CORESET to indicate the resource distribution of RMSI PDSCH, can be with saving signaling expense.

In the application, the time location for sending SS/PBCH block refers to the lasting symbolic range of SS/PBCH block (4 symbols as specified in NR).In the application, send RMSI PDSCH time location refer to SS/PBCH block into The time-multiplexed RMSI PDSCH of row lasting symbolic range.

In scheme one, sends the time location of the corresponding RMSI PDSCH of SS/PBCH block and send the SS/PBCH The time location continuous adjacent of block refers to that the next symbol for the last symbol that the SS/PBCH block is occupied i.e. should First symbol that RMSI PDSCH is occupied.For example, a SS/PBCH block occupies symbol 0-3, the SS/PBCH block Corresponding RMSI PDSCH occupies symbol 4-27.In other words, the time location for sending the RMSI PDSCH is located next to (adjacent to) sends the time location of the SS/PBCH block.

In scheme two, sends the time location of SS/PBCH block (carrying MIB), sends the SS/PBCH block couple The time location of the RMSI CORESET answered sends the corresponding RMSI PDSCH (carrying RMSI) of the SS/PBCH block Time location continuous adjacent refers to, the next symbol i.e. RMSI for the last symbol which occupies First symbol that CORESET is occupied, the next symbol i.e. RMSI for the last symbol which occupies First symbol that PDSCH is occupied.For example, a SS/PBCH block occupies symbol 0-3, the SS/PBCH block is corresponding RMSI CORESET occupies symbol 4-7, and the corresponding RMSI PDSCH of the SS/PBCH block occupies symbol 8-27.In other words, The time location for sending the SS/PBCH block sends the time location of the RMSI PDSCH, hair next to (adjacent to) The time location for giving the time location of the RMSI PDSCH to send the SS/PBCH block next to (adjacent to).

In the application, the principal element for influencing the resource mapping method of SS/PBCH block and RMSI PDSCH may include But it is not limited to:

(1) time location of SS/PBCH block is sent

Specifically, one or more SS/PBCH can be arranged in the time window (such as 1ms time window) of specific length The corresponding preset time position block.

In one implementation, the time location for sending SS/PBCH block can be the SS/PBCH block in spy Corresponding preset time position in the time window of measured length.SS/PBCH block is sent in fixed position.

In another implementation, the time location for sending SS/PBCH block can not be the SS/PBCH block The corresponding preset time position in the time window of specific length.SS/PBCH block is sent not at a fixed location.

In the application, the time window of the specific length is properly termed as first time window.It is not limited to 1ms, at the first time The duration of window can not be applied with no restriction with longer (such as 2ms) or shorter (such as 0.5ms).

It about the time location for sending SS/PBCH block, can be discussed in detail in subsequent embodiment, not repeat first here.

(2) duration (i.e. lasting symbolic number) of RMSI PDSCH

The duration of RMSI PDSCH can be with following factor in relation to the big of: the payload (payload) of RMSI PDSCH The demodulated reference signal in modulation coding scheme (MCS) and RMSI PDSCH that small, RMSIPDSCH is used The resource distribution of (demodulation reference signal, DMRS).It is to be understood that being needed in RMSI PDSCH information Configuration DMRS assists terminal device solution adjusting data, therefore, different, the RMSI PDSCH lasting symbolic number of the resource distribution of DMRS Also it can be varied.

1. having been defined according in NR to RMSI PDSCH, the payload of RMSI PDSCH probably includes 1700 ratios Special information.Some of them information word is option.When the network equipment is without sending these optional information words, RMSI The size of the payload of PDSCH is about 1000 bits.

2. having been defined according in NR to RMSI PDSCH, the order of modulation of RMSI PDSCH is fixed as 2.RMSI The corresponding modulation coding scheme of PDSCH (MCS) and spectrum efficiency (i.e. the bit number that can be carried on a subcarrier) can be such as tables 2 It is shown.It is to be understood that under given channel bandwidth (such as 20MHz) and given MCS (such as MCS=0), according to the frequency spectrum in table 2 Efficiency can calculate the bit number that 1 RB on single symbol can be carried, and may further calculate single symbol (as wrapped Include 24 RB) bit number that can carry, it can finally calculate the RMSI PDSCH of given size (such as 1700 bits) Payload needs to continue how many a symbols.

MCS index	Order of modulation	Spectrum efficiency
			0	2	0.2344
1	2	0.3066
			2	2	0.3770
3	2	0.4902
			4	2	0.6016
5	2	0.7402
			6	2	0.8770

Figure 14 has also embodied SS/PBCH block provided by the present application, RMSI CORESET, RMSI PDSCH sender The application scenarios that case is related to, that is, work the random access scene in the communication system of unauthorized frequency range.It is not limited to shown in Figure 14, Other processes can also be performed before random access procedure, between the network equipment and terminal, such as random access prepares.

Below by multiple embodiments detailed description scheme one provided by the present application, scheme two.

(1) embodiment one

The present embodiment uses scheme one, the i.e. time location of the corresponding RMSIPDSCH of transmission SS/PBCH block and transmission The time location continuous adjacent of the SS/PBCH block.Here, which it is to be sent to can be any one SS/PBCH block。

Figure 15 illustrates a kind of possible resource impact pattern (pattern).As shown in figure 15, in initial part Bandwidth (initial bandwidth part, BWP) is 20MHz, and subcarrier spacing is 1ms time window under the scene of 60KHz 56 OFDM symbols are inside shared, 1ms time window includes 2 SS/PBCH block (SS/PBCH block1 and SS/PBCH ) and this corresponding RMSI PDSCH of 2 SS/PBCH block block2.Wherein, this 2 SS/PBCH block are lasting 4 symbols, position is sent this 2 SS/PBCH block at the following time respectively: symbol 0-3 and symbol 28-31, they Position is sent corresponding RMSI PDSCH at the following time respectively: symbol 4-27 and symbol 32-55.

That is, SS/PBCH block1 RMSI PDSCH1 continuous adjacent corresponding with its, SS/PBCH block2 and its correspondence RMSI PDSCH2 continuous adjacent.This way it is possible to avoid the network equipment lose channel, it can be ensured that SS/PBCH block1 and its The complete system information that corresponding RMSI PDSCH1 is carried jointly is disposably completely sent, SS/PBCH block2 and The complete system information that its corresponding RMSI PDSCH2 is carried jointly is disposably completely sent, and terminal device is improved It is initially accessed efficiency.

In addition, as shown in figure 15, on symbol 4-27, symbol 32-55, RMSI PDSCH takes the initial of entire 20MHz Fractional bandwidth (including 24 RB).Here, initial part bandwidth (BWP) refers to what the network equipment allowed to access after LBT success Bandwidth.In other words, on the lasting symbol of RMSI PDSCH, RMSI PDSCH can take entire initial part on frequency domain Bandwidth, channel width occupancy are 100%.In this way, the transmission of RMSI PDSCH may make to meet OCB requirement, and can keep away Exempt to indicate occupation condition of the RMSI PDSCH on frequency domain, saving signaling expense.

Optionally, as shown in figure 15, on the lasting symbol of SS/PBCH block, part RMSI PDSCH can be used The RB not occupied by SS/PBCH block is filled, can reach the reception of strengthening part RMSI PDSCH.

It has been specified that indicating the resource distribution of RMSI CORESET by PBCH in NR, carried by RMSI CORESET Instruction information (such as DCI) indicate the configuration information (including running time-frequency resource position and MCS) of RMSI PDSCH.But this Need terminal that could finally read the system information RMSI of RMSI PDSCH carrying by multiple steps.

In embodiment one, RMSI CORESET is not needed to indicate the resource distribution of RMSI PDSCH, SS/PBCH block It is middle to carry instruction information (the i.e. first instruction information) to indicate the resource distribution of RMSI PDSCH.It is analyzed as follows below:

Typical RMSI CORESET (using DCI format 1_0) includes following information defined in NR:

1.Frequency domain/time domain resource assignment (time-frequency resource indication)

2.VRB-to-RB mapping (physical resource mapping mode)

3.Modulation and coding scheme (modulation coding scheme)

4.Redundancy version (redundant version number)

5.HARQ process number (No. HARQ)

6.Downlink assignment index (downlink distribution index)

7.TPC command for scheduled PUCCH (ascending control information power control)

8.PUCCH resource indicator (instruction of ascending control information resource)

9.PDSCH-to-HARQ feedback timing indicator (instruction of HARQ feedback moment)

Above- mentioned information major part and HARQ, uplink is related, is not used to the configuration information of instruction RMSI PDSCH.With Only include in the necessary information of the configuration information of instruction RMSI PDSCH:

2.VRB-to-RB mapping (physical resource mapping mode)

3.Modulation and coding scheme (modulation coding scheme)

The lower above-mentioned several necessary informations of surface analysis are respectively necessary for how many bit to indicate.

A. for " Modulation and coding scheme ", what it is due to RMSI PDSCH carrying is system information, It is critically important for the initial access of terminal device, therefore, RMSI PDSCH transmitted using lower MCS (such as MCS 0 or MCS 1/2/3).It should be understood that lower MCS (such as MCS 0 or MCS 1/2/3) only needs 1 or 2 bit indications.

B. for " Frequency domain/time domain resource assignment ", in RMSI PDSCH On lasting symbol, RMSI PDSCH can take entire initial part bandwidth (as shown in figure 15), i.e. RMSI on frequency domain The frequency domain resource occupancy situation (" Frequency domainresource assignment ") of PDSCH is without being indicated.Separately Outside, under given channel bandwidth, different MCS will lead to the lasting symbolic number difference of RMSI PDSCH, specifically refer to aforementioned Several Typical Dispositions of RMSI PDSCH under the 20MHz channel width referred in content lasting symbolic number, such as RMSI PDSCH continues 27/26/16/17/15/20/21 OFDM symbol.At this point, the time-domain resource occupancy situation of RMSI PDSCH (" time domainresource assignment ") can be indicated with 1-3 bit.

C. " VRB-to-RB mapping " only needs 1 bit indication.

As can be seen that above-mentioned several necessary informations need 3-5 bit to indicate in total.8 in PBCH are provided in NR Bit is used to indicate the running time-frequency resource position of RMSI CORESET.It is different to the definition of this 8 bit from NR, in embodiment one, RMSI CORESET is not needed to indicate the resource distribution of RMSI PDSCH, and it is above-mentioned to indicate using this 8 bit in PBCH Several necessary informations.In other words, this 8 bit in PBCH may be used to indicate the resource distribution of RMSI PDSCH, specifically can be with It is used to indicate the duration (such as lasting symbolic number) of RMSI PDSCH.That is, the first instruction carried in SS/PBCH block Information can be this 8 bit in PBCH.

It should be understood that indicating the resource distribution of RMSI PDSCH due to not needing RMSI CORESET, and use This 8 bit in PBCH indicates the resource distribution of RMSI PDSCH.Therefore, terminal after receiving SS/PBCH block just RMSI PDSCH can be received and demodulate according to this 8 bit, to obtain the RMSI carried in RMSI PDSCH.Compared in NR For the defined resource distribution for indicating RMSI PDSCH by RMSI CORESET, this instruction of the offer of embodiment one The mode of the resource distribution of RMSI PDSCH can reduce the step of terminal device obtains system information RMSI, also because eliminating RMSI CORESET and saved signaling overheads.

Table 3 illustratively shows several RMSI PDSCH configuration of the first instruction information (8 bits in PBCH) instruction.

Configuration index	The frequency domain resource that RMSI is occupied	RMSI lasting symbolic number	Modulation coding scheme
				0	24	16	0
1	24	17	0
				2	24	20	1
3	24	21	1

Table 3

Table 3 is used only for explaining the application, is not limited to shown in table 3, and the first instruction information (8 bits in PBCH) can refer to Other situations can also be presented in the RMSI PDSCH configuration shown.

Illustrate the resource mapping method of SS/PBCH block and RMSI PDSCH below.

(1) time location for sending SS/PBCH block is fixed

In one implementation, the time location for sending SS/PBCH block can be the SS/PBCH block the Corresponding preset time position in one time window.SS/PBCH block is sent in fixed position.First time window is spy The time window of measured length, such as 1ms time window.First time window may include one or more SS/PBCH block respectively Corresponding preset time position.

In the application, the time index (time index) in the PBCH of SS/PBCH block can indicate the SS/PBCH Index of the block in first time window indicates the SS/PBCH block is which SS/ in first time window PBCH block.In this way, given under subcarrier spacing in given bandwidth, after terminal detects a SS/PBCH block, Terminal can determine SS/PBCH according to the time index (time index) that PBCH in the SS/PBCH block is carried Block is which of first time window SS/PBCH block, then obtains the SS/PBCH block at the first time Corresponding preset time position (i.e. symbol/time slot number) in window, and pass through the subframe numbers (subframe in PBCH Number, SFN) obtain complete time synchronization.

Optionally, it is not enough to fill in the payload of RMSI PDSCH two adjacent default in first time window Under conditions of time interval (interval) between time location, the symbol for not carrying RMSI PDSCH in the time interval can It is filled by the first downlink signal.Here, the first downlink signal may include other downlink signals (such as CSI-RS reference signal), and Non- SS/PBCH block.

For example, as shown in Figure 16 A, under 20MHz channel width, the scene of SCS=60KHz, 1ms time window includes 2 The corresponding preset time position of a SS/PBCH block (SS/PBCH block1, SS/PBCH block2): symbol 0-3, symbol 28-31.Time interval between two adjacent preset time positions is 24 symbols.And the corresponding RMSI of SS/PBCH block1 PDSCH1 is sent on symbol 4-23, and the corresponding RMSI PDSCH2 of SS/PBCH block2 is sent on symbol 32-51, Continue 20 symbols, is not enough to take the time interval.The network equipment can be in blank character (i.e. symbol 24-27, symbol The first downlink signal is filled in 52-55).Here, blank character refers to the symbol of non-bearing downlink signal.In this way, can avoid because The time interval does not have downlink signal to send and discontinuously dispatching occur, avoids losing channel access power, it can be achieved that multiple systems Information (carrying in multiple SS/PBCH block and its corresponding RMSI PDSCH) is disposably completely sent.

(2) time location for sending SS/PBCH block is not fixed

In another implementation, the time location for sending SS/PBCH block can not be the SS/PBCH block The corresponding preset time position in first time window.SS/PBCH block is sent not at a fixed location.The another kind is real The payload of the existing especially suitable RMSI PDSCH of mode is not enough to fill two adjacent preset times in first time window The case where time interval (interval) between position.

Specifically, being not enough to fill in the payload of RMSI PDSCH two adjacent default in first time window Under conditions of time interval (interval) between time location, send the corresponding RMSI PDSCH's of SS/PBCH block The time location continuous adjacent of next SS/PBCH block of time location and transmission the SS/PBCH block.

For example, as shown in fig 16b, under 20MHz channel width, the scene of SCS=60KHz, 1ms time window includes 2 The corresponding preset time position of a SS/PBCH block (SS/PBCH block1, SS/PBCH block2) are as follows: symbol 0-3, symbol Number 28-31.Time interval between the two adjacent preset time positions is 24 symbols.And SS/PBCH block1 is corresponding RMSI PDSCH1 is sent on symbol 4-23, the corresponding RMSI PDSCH2 of SS/PBCH block2 quilt on symbol 32-51 It sends, continues 20 symbols, be not enough to take the time interval.As shown in fig 16b, in 1ms time window, SS/ PBCH block1 can be sent on its corresponding preset time position (i.e. symbol 0-3), send SS/PBCH block2's Time location (symbol 24-27) is next to time location (the symbol 4- for sending the corresponding RMSI PDSCH of SS/PBCH block1 23).In this way, can avoid discontinuously dispatching occur because the time interval does not have downlink signal transmission, avoid losing channel access It weighs, it can be achieved that multiple system informations (carrying in multiple SS/PBCH block and its corresponding RMSI PDSCH) are by one The complete transmission of secondary property.

In the unfixed situation of time location for sending SS/PBCH block, when terminal detects a SS/PBCH After block, in addition to the time index (time index) that PBCH is carried, terminal also needs the symbol lasting according to RMSI PDSCH Number determines the index of the index of system-frame locating for system timing information, the index of subframe, symbol, and it is same to obtain Cell time Step.

In the resource mapping method of above-mentioned (1) or (2) description, optionally, deposited in the near border of first time window Under conditions of blank character, which can be filled by the first downlink signal.Here, blank character, which refers to, does not carry down The symbol of row signal.

It is to be understood that being not limited to NR-U system, embodiment one can also be applied in NR system.Although network in NR system Equipment does not need to obtain channel access power by LBT, and there is no lose channel access power.But in example 1, RMSI PDSCH and SS/PBCH block continuous adjacent in the time domain, it may not be necessary to which RMSI CORESET indicates RMSI The resource distribution of PDSCH, the resource distribution of the first instruction information instruction RMSI PDSCH carried in SS/PBCH block is i.e. Can, equally can in NR system saving signaling expense.

It should be understood that embodiment one, which can avoid the network equipment, loses channel, realize system information by disposable complete It sends, improves the initial access efficiency of terminal device.Moreover, because not needing RMSI CORESET to indicate RMSI PDSCH's Resource distribution, therefore can be with saving signaling expense.

The related expanding scheme of embodiment one

With reference to foregoing teachings it is found that the duration of RMSI PDSCH can be related with following factor: RMSI PDSCH's Modulation coding scheme (MCS) that the size of payload (payload), RMSIPDSCH are used and the DMRS's in RMSI PDSCH Resource distribution.When these factors change, the duration of RMSI PDSCH is it can also happen that variation.

It is 20MHz in initial part bandwidth, SCS is that 56 OFDM symbols are shared in 1ms time window under the scene of 60KHz Number.For the lasting symbolic number of several different RMSI PDSCH, it is corresponding with its that SS/PBCH block is given below Several resource mapping methods of RMSIPDSCH:

(1) situation 1: when RMSI PDSCH continues symbolic number≤10,1 SS/PBCH block corresponding RMSI PDSCH continues 14 symbols altogether, then 4 SS/PBCH block and its corresponding can be at most placed in 1ms time window RMSI PDSCH, possible mapping mode are as follows:

Option 1: the time location for sending SS/PBCH block is fixed.1ms time window includes multiple SS/PBCH The corresponding preset time position block, comprising: symbol 0~3, symbol 14~17, symbol 28~31, symbol 42~45. The corresponding RMSI PDSCH of SS/PBCH block 1~4 lasting symbolic range is respectively as follows: symbol 4~13, and symbol 18~ 27, symbol 32~41, symbol 46~55.When the RMSI PDSCH duration is less than 10 symbols, next SS/PBCH There are blank character between block and the corresponding RMSI PDSCH of a upper SS/PBCH block, the network equipment is needed in the sky White symbol sends other downlink signals and is filled.

Option 2: the time location for sending SS/PBCH block is not fixed.SS/PBCH block RMSI corresponding with its PDSCH is continuously transmitted, and next SS/PBCH block is next to the corresponding RMSI PDSCH hair of a upper SS/PBCH block It send, as shown in fig 16b.When RMSI PDSCH continues m (m is positive integer, m < 10) a symbol, SS/ is sent in 1ms window The time location of PBCH block 1~4 is respectively as follows: symbol 0~3, symbol (4+m)~(7+m), symbol (8+2m)~(11+ 2m), symbol (12+3m)~(15+3m).The corresponding RMSI PDSCH of SS/PBCH block 1~4 lasting symbolic range It is respectively as follows: symbol 4~(3+m), symbol (8+m)~symbol (7+2m), symbol (12+2m)~symbol (11+3m), symbol (16+ 3m)~(15+4m).When the RMSI PDSCH duration is less than 10 symbols, i.e. when 15+4m < 55, the last one RMSI PDSCH and 1ms time window boundary there are blank character, the network equipment need the blank character send other downlink signals into Row filling.

(2) situation 2: when RMSI PDSCH continues symbolic number≤3,1 SS/PBCH is held altogether with corresponding RMSI PDSCH Continue 7 symbols, then can at most place 8 SS/PBCH block and corresponding RMSI PDSCH in 1ms time window, it is possible Mapping mode is as follows:

Option 1: the time location for sending SS/PBCH block is fixed.1ms time window includes multiple SS/PBCH The corresponding preset time position block, comprising: symbol 0~3, symbol 7~10, symbol 14~17, symbol 21~24, symbol Numbers 28~31, symbol 35~38, symbol 42~45, symbol 49~52.The corresponding RMSI of SS/PBCH block 1~8 PDSCH lasting symbolic range is respectively as follows: symbol 4~6, symbol 11~13, symbol 18~20, symbol 25~27, and symbol 32~ 34, symbol 39~41, symbol 46~48, symbol 53~55.When the RMSI PDSCH duration is less than 3 OFDM symbols, under There are blank character between one SS/PBCH block RMSI PDSCH corresponding with a upper SS/PBCH block, network is set Standby needs send other downlink signals in the blank character and are filled.

Option 2: the time location for sending SS/PBCH block is not fixed.SS/PBCH block RMSI corresponding with its PDSCH is continuously transmitted, and next SS/PBCH block is next to the corresponding RMSI PDSCH hair of a upper SS/PBCH block It send, as shown in fig 16b.When RMSI PDSCH continues n (n is positive integer, n < 3) a symbol, SS/ is sent in 1ms window The time location of PBCH block 1~8 is respectively as follows: symbol 0~3, symbol (4+n)~(7+n), symbol (8+2n)~(11+ 2n) symbol (12+3n)~(15+3n), symbol (16+4n)~(19+4n), symbol (20+5n)~(23+5n), symbol (24+ 6n)~(27+6n), symbol (28+7n)~(31+7n).The corresponding RMSI PDSCH of SS/PBCH block 1~8 continues Symbolic range be respectively as follows: symbol 4~(3+n), symbol (8+n)~(7+2n), symbol (12+2n)~(11+3n), symbol (16+ 3n)~(15+4n), symbol (20+4n)~(19+5n), symbol (24+5n)~(23+6n), symbol (28+6n)~(27+7n), Symbol (32+7n)~(31+8n).When the RMSI PDSCH duration is less than 3 symbols, i.e. when 31+8n < 55, the last one There are blank character, the network equipment needs to send other downlinks in the blank character for RMSI PDSCH and 1ms time window boundary Signal is filled.

Above-mentioned several situations are not limited to, RMSI PDSCH lasting symbolic number can also be other values.In RMSI In the case that PDSCH lasting symbolic number is other values, the resource mapping method of SS/PBCH block and RMSI PDSCH can It is similar to determine, no longer it is unfolded one by one.

In addition, embodiment one discusses the resource mapping method under 20MHz channel width and the scene of SCS=60KHz And the symbolic number that RMSI PDSCH is lasting, under other bandwidth and the scene of SCS, RMSI PDSCH lasting symbolic number and Resource mapping method follows identical strategy.For example, under 80MHz channel width and the scene of SCS=15KHz, RMSI PDSCH lasting symbolic number is equally related to the payload size of RMSI PDSCH, MCS and the DMRS of use configuration, and difference exists In the available RB number for including on single symbol is different, and the amount of bits that single symbol can carry is different.In Figure 17 Table show the available RB quantity under several different bandwidths and different SCS on single symbol.

(2) embodiment two

The present embodiment uses scheme two, that is, sends the time location of SS/PBCH block (carrying MIB), sends the SS/ The time location of the corresponding RMSI CORESET of PBCH block sends the corresponding RMSI PDSCH of the SS/PBCH block and (holds Carried RMSI) time location continuous adjacent.Here, which can be any one SS/PBCH to be sent block。

In embodiment two, according to the regulation in NR, the resource distribution of RMSI CORESET is by SS/PBCH block PBCH instruction, the resource distribution of RMSI PDSCH are indicated by RMSI CORESET.

Figure 18 illustrates a kind of possible resource impact pattern (pattern).As shown in figure 18, in initial part Bandwidth (BWP) is 20MHz, and subcarrier spacing is that 56 OFDM symbols are shared in 1ms time window under the scene of 60KHz.As before State a kind of Typical Disposition described in content, sustainable 20 OFDM symbols of RMSI PDSCH.When RMSI CORESET continues 4 OFDM symbol, can be accommodated when SS/PBCH block continues 4 symbols, in 1ms time window 2 SS/PBCH block and its Corresponding RMSI CORESET, RMSI PDSCH.Wherein, this 2 SS/PBCH block are respectively in following fixed position quilt Send: symbol 0-3 and symbol 28-31, position is sent the corresponding RMSI CORESET of each at the following time respectively: Symbol 4-7 and symbol 32-35, position is sent the corresponding RMSI PDSCH of each at the following time respectively: symbol 8- 27 and symbol 36-55.

That is, SS/PBCH block1 RMSI CORESET1 corresponding with its, RMSI PDSCH1 continuous adjacent, SS/PBCH Block2 RMSI CORESET2 corresponding with its, RMSI PDSCH2 continuous adjacent.This way it is possible to avoid the network equipment loses letter Road, it can be ensured that the complete system information that SS/PBCH block1 RMSI PDSCH1 corresponding with its is carried jointly is disposable Complete transmission, the complete system information that SS/PBCH block2 RMSI PDSCH2 corresponding with its is carried jointly is primary The complete transmission of property, improves the initial access efficiency of terminal device.

In addition, as shown in figure 18, on symbol 4-7, symbol 32-35, RMSI CORESET takes the initial of entire 20MHz Fractional bandwidth (including 24 RB).On symbol 8-27, symbol 36-55, RMSI PDSCH takes the initial part of entire 20MHz Bandwidth (including 24 RB).Here, initial part bandwidth (BWP) refers to the bandwidth that the network equipment allows to access after LBT success.

In other words, on RMSI CORESET, RMSI PDSCH respectively lasting symbol, RMSI CORESET, RMSI PDSCH can take entire initial part bandwidth on frequency domain, and channel width occupancy is 100%.In this way, may make RMSI The transmission of CORESET, RMSI PDSCH meet OCB requirement, and can exist to avoid instruction RMSI CORESET, RMSI PDSCH Occupation condition on frequency domain, saving signaling expense.

In NR, the configuration information of RMSI CORESET is carried in PBCH, totally 8 bit.In example 2, in initial portion Point bandwidth (BWP) is 20MHz, and subcarrier spacing is under the scene of 60KHz, when the RMSI CORESET in NR-U is sent Meta position is set to 4 symbols after the time location for sending SS/PBCH block, and RMSI CORESET is accounted on frequency domain When full entire BWP, possible RMSI CORESET configuration can be as shown in table 4 in NR-U, it is only necessary to it can be indicated with 2 bits, Remaining 6 bit can be used as other instructions.

Index	Available RB quantity	Symbol quantity

			2	24	4

Table 4

When using 2 bit indication RMSI CORESET lasting symbolic number, in addition to table 4 provide it is 3 kinds long be outside one's consideration, this 2 Bit also can indicate that RMSI CORESET continues the case where symbolic number is 3, or can indicate that continuing symbolic number is 1/2/3/4 Some subset formed, such as { 1,2,4 }, { 1,3,4 } etc..Remaining 6 bit information may be used as other instructions.When only using PBCH In 1 bit come when indicating the lasting symbolic number of RMSI CORESET, RMSI CORESET lasting symbolic number can for 2 or 4 OFDM symbols of person.

In the case where RMSIPDSCH lasting symbolic number is greater than 14, RMSI CORESET needs to indicate RMSIPDSCH's Across timeslot scheduling information.In NR, the network equipment needs to first pass through wireless heterogeneous networks before across timeslot scheduling RMSIPDSCH Phase of (radio resource control, the RRC) signaling to terminal equipment configuration time slot polymerization (slot aggregation) Parameter aggregationFactorDL is closed, then is indicated by DCI across timeslot scheduling.However, not completed also in NR-U system The terminal of initial access can not obtain relevant parameter aggregationFactorDL by RRC signaling.In this regard, can be Configuration index (such as Index of 8 bits) indicates the lasting symbolic number of RMSIPDSCH in RMSI CORESET, specifically can be such as table 5 It is shown.Table 5 illustrate in across timeslot scheduling RMSIPDSCH by the index (such as 0-3) in RMSI CORESET come Indicate the mode of the lasting symbolic number of RMSIPDSCH.

Index	Available RB quantity	Symbol quantity	MCS

Table 5

Optionally, on RMSI CORESET, RMSI PDSCH respectively lasting symbol, RMSI CORESET, RMSI PDSCH can also not extend around entire initial part bandwidth on frequency domain, and such network equipment can also be by RMSI Other downlink signals are sent on the RB that CORESET/RMSI PDSCH is occupied.

Illustrate the resource mapping method of SS/PBCH block, RMSI CORESET and RMSI PDSCH below.

(1) time location for sending SS/PBCH block is fixed

In the application, the time index (time index) in the PBCH of SS/PBCH block can indicate the SS/PBCH Index of the block in first time window indicates the SS/PBCH block is which SS/ in first time window PBCH block.In this way, terminal is according to PBCH in the SS/PBCH block after terminal detects a SS/PBCH block The time index (time index) of carrying can determine the index of system-frame locating for system timing information, the rope of subframe Draw, the index of symbol, it is synchronous to obtain Cell time.

Optionally, it is less than two phases in first time window in the duration of RMSI CORESET and RMSI PDSCH Under conditions of time interval (interval) between adjacent preset time position, RMSI is not carried in the time interval The symbol of CORESET or RMSI PDSCH can be filled by the first downlink signal.

For example, being 20MHz at initial part bandwidth (BWP), subcarrier spacing is the scene of 60KHz as shown in Figure 19 A Under, 56 OFDM symbols are shared in 1ms time window.1ms time window includes 2 SS/PBCH block (SS/PBCH Block1, SS/PBCH block2) corresponding preset time position: symbol 0-3, symbol 28-31.Two adjacent preset time positions Time interval between setting is 24 symbols.And the corresponding RMSI CORESET1 of SS/PBCH block1, RMSI PDSCH1 are total Continue 20 symbols, the corresponding RMSI CORESET2 of SS/PBCH block2, RMSI PDSCH2 continue 20 symbols altogether, insufficient To take time interval.The network equipment the first downlink of filling can be believed in blank character (i.e. symbol 24-27, symbol 52-55) Number.Here, blank character is the symbol of non-bearing downlink signal.In this way, can avoid there is no downlink signal hair because of the time interval It send and discontinuously dispatching occurs, avoid losing channel access power, it can be achieved that multiple system informations (are carried in multiple SS/PBCH In block and its corresponding RMSI PDSCH) disposably completely sent.

Here, the duration of RMSI CORESET and RMSI PDSCH are less than two adjacent in first time window Time interval (interval) between preset time position shows that the payload of RMSI CORESET and RMSI PDSCH are big It is small to be not enough to fill the time interval.

(2) time location for sending SS/PBCH block is not fixed

In another implementation, the time location for sending SS/PBCH block can not be the SS/PBCH block The corresponding preset time position in first time window.SS/PBCH block is sent not at a fixed location.The another kind is real The payload of existing mode especially suitable RMSI CORESET and RMSI PDSCH is not enough to fill two in first time window The case where time interval (interval) between adjacent preset time position.

Specifically, being less than two phases in first time window in the duration of RMSI CORESET and RMSI PDSCH Under conditions of time interval (interval) between adjacent preset time position, send next SS/PBCH block when Between position RMSI PDSCH corresponding with current SS/PBCH block is sent time location continuous adjacent.

For example, being 20MHz at initial part bandwidth (BWP), subcarrier spacing is the scene of 60KHz as shown in Figure 19 B Under, 56 OFDM symbols are shared in 1ms time window.1ms time window includes 2 SS/PBCH block (SS/PBCH Block1, SS/PBCH block2) corresponding preset time position: symbol 0-3, symbol 28-31.Two adjacent preset time positions Time interval between setting is 24 symbols.And the corresponding RMSI CORESET1 of SS/PBCH block1, RMSI PDSCH1 are total Continue 20 symbols, the corresponding RMSI CORESET2 of SS/PBCH block2, RMSI PDSCH2 continue 20 symbols altogether, insufficient To take time interval.As shown in fig 16b, in 1ms time window, SS/PBCH block1 can be corresponding default at its It is sent on time location (i.e. symbol 0-3), sends the time location (symbol 24-27) of SS/PBCH block2 next to transmission The time location (symbol 4-23) of the corresponding RMSI PDSCH of SS/PBCH block1.In this way, can avoid not having because of the time interval There is downlink signal to send and discontinuously dispatching occur, avoids losing channel access power, it can be achieved that multiple system informations (are carried more In a SS/PBCH block and its corresponding RMSI PDSCH) disposably completely sent.

In the resource mapping method of above-mentioned (1) or (2) description, optionally, deposited in the near border of first time window Under conditions of blank character, which can be filled by the first downlink signal.Here, blank character, which refers to, does not carry down The symbol of row signal.In this way, can avoid discontinuously dispatching occur because the blank character does not have downlink signal transmission, avoid losing Channel access is weighed, it can be achieved that multiple first time windows are continuously transmitted.

It should be understood that embodiment two, which can avoid the network equipment, loses channel, realize system information by disposable complete It sends, improves the initial access efficiency of terminal device.

The related expanding scheme of embodiment two

It is 20MHz in initial part bandwidth, SCS is that 56 OFDM symbols are shared in 1ms time window under the scene of 60KHz Number.For the lasting symbolic number of several different RMSI PDSCH, SS/PBCH block RMSI corresponding with its is given below Several resource mapping methods of PDSCH:

(1) situation 1: when RMSI CORESET continues symbolic number≤10 plus RMSI PDSCH, 1 SS/PBCH Block corresponding RMSI CORESET and RMSI PDSCH continues 14 symbols altogether, then can at most put in 1ms time window It sets 4 SS/PBCH block and its corresponding RMSI CORESET and RMSI PDSCH, possible mapping mode is as follows:

Option 1: the time location for sending SS/PBCH block is fixed.1ms time window includes multiple SS/PBCH The corresponding preset time position block, comprising: symbol 0~3, symbol 14~17, symbol 28~31, symbol 42~45. 1~4 corresponding RMSI CORESET and RMSI PDSCH of SS/PBCH block lasting symbolic range is respectively as follows: symbol 4~13, symbol 18~27, symbol 32~41, symbol 46~55.It is less than when RMSI CORESET and RMSI the PDSCH duration When 10 symbols, there is sky between next SS/PBCH block and the corresponding RMSI PDSCH of a upper SS/PBCH block White symbol, network equipment needs send other downlink signals in the blank character and are filled.

Option 2: the time location for sending SS/PBCH block is not fixed.SS/PBCH block RMSI corresponding with its CORESET, RMSI PDSCH are continuously transmitted, and next SS/PBCH block is corresponding next to a upper SS/PBCH block RMSI CORESET and RMSI PDSCH are sent, as shown in Figure 19 B.When RMSI CORESET and RMSI PDSCH continue m, (m is Positive integer, m < 10) a OFDM symbol when, in 1ms window send block1~4 SS/PBCH time location difference Are as follows: symbol 0~3, symbol (4+m)~(7+m), symbol (8+2m)~(11+2m), symbol (12+3m)~(15+3m).SS/PBCH 1~4 corresponding RMSI CORESET and RMSI PDSCH of block lasting symbolic range is respectively as follows: symbol 4~(3+ M), symbol (8+m)~symbol (7+2m), symbol (12+2m)~symbol (11+3m), symbol (16+3m)~(15+4m).Work as RMSI When CORESET the and RMSI PDSCH duration is less than 10 OFDM symbols, i.e. when 15+4m < 55, the last one RMSI PDSCH With 1ms time window boundary there are blank character, network equipment needs send other downlink signals in the blank character and are filled out It fills.

(2) situation 2: when RMSI CORESET and RMSI PDSCH continue symbolic number≤3,1 SS/PBCH is corresponding RMSI CORESET and RMSI PDSCH continue 7 symbols altogether, then 8 SS/PBCH can be at most placed in 1ms time window Block and its corresponding RMSI CORESET and RMSI PDSCH, possible mapping mode are as follows:

Option 1: the time location for sending SS/PBCH block is fixed.1ms time window includes multiple SS/PBCH The corresponding preset time position block, comprising: symbol 0~3, symbol 7~10, symbol 14~17, symbol 21~24, symbol Numbers 28~31, symbol 35~38, symbol 42~45, symbol 49~52.The corresponding RMSI of SS/PBCH block 1~8 CORESET and RMSI PDSCH lasting symbolic range is respectively as follows: symbol 4~6, symbol 11~13, symbol 18~20, symbol 25 ~27, symbol 32~34, symbol 39~41, symbol 46~48, symbol 53~55.When RMSI CORESET and RMSI PDSCH are held When the continuous time is less than 3 OFDM symbols, next SS/PBCH block RMSI corresponding with a upper SS/PBCH block There are blank character between PDSCH, network equipment needs send other downlink signals in the blank character and are filled.

Option 2: the time location for sending SS/PBCH block is not fixed.SS/PBCH block RMSI corresponding with its CORESET, RMSI PDSCH are continuously transmitted, and next SS/PBCH block is corresponding next to a upper SS/PBCH block RMSI CORESET and RMSI PDSCH are sent, as shown in Figure 19 B.When to continue n (n is positive integer, n < 3) a by RMSI PDSCH When symbol, the time location that SS/PBCH block 1~8 is sent in 1ms window is respectively as follows: symbol 0~3, and symbol (4+n)~ (7+n), symbol (8+2n)~(11+2n) symbol (12+3n)~(15+3n), symbol (16+4n)~(19+4n), symbol (20+ 5n)~(23+5n), symbol (24+6n)~(27+6n), symbol (28+7n)~(31+7n).SS/PBCH block 1~8 is respective Corresponding RMSI CORESET and RMSI PDSCH lasting symbolic range is respectively as follows: symbol 4~(3+n), symbol (8+n)~(7 + 2n), symbol (12+2n)~(11+3n), symbol (16+3n)~(15+4n), symbol (20+4n)~(19+5n), symbol (24+ 5n)~(23+6n), symbol (28+6n)~(27+7n), symbol (32+7n)~(31+8n).As RMSI CORESET and RMSI When the PDSCH duration is less than 3 symbols, i.e. when 31+8n < 55, the last one RMSI PDSCH and 1ms time window boundary is deposited In blank character, network equipment needs send other downlink signals in the blank character and are filled.

Above-mentioned several situations are not limited to, RMSI PDSCH lasting symbolic number can also be other values.In RMSI In the case that PDSCH lasting symbolic number is other values, SS/PBCH block, RMSI CORESET and RMSI PDSCH's Resource mapping method similar can be determined, no longer be unfolded one by one.

In addition, embodiment two discusses the resource mapping method under 20MHz channel width and the scene of SCS=60KHz And the symbolic number that RMSI PDSCH is lasting, under other bandwidth and the scene of SCS, RMSI PDSCH lasting symbolic number and Resource mapping method follows identical strategy.For example, under 80MHz channel width and the scene of SCS=15KHz, RMSI PDSCH lasting symbolic number is equally related to the payload size of RMSI PDSCH, MCS and the DMRS of use configuration, and difference exists In the available RB number for including on single symbol is different, and the amount of bits that single symbol can carry is different.In Figure 17 Table show the available RB quantity under several different bandwidths and different SCS on single symbol.

(3) embodiment three

Embodiment three gives the resource mapping method of SS/PBCH block and RMSI PDSCH under ECP scene.

When the radius of society that NR-U is needed support is larger, in order to cope with multi-path jamming, need using expansion cyclic prefix (Extended Cyclic Prefix, ECP).It is 20MHz in initial part bandwidth, SCS is the scene of 60KHz for ECP Under, it include 48 OFDM symbols in 1ms time window.When RMSI PDSCHpayload size is 1000 bits, and RMSI When PDSCH uses the Type 1DMRS of 1 symbol, RMSI PDSCH continues 20 OFDM symbols.At this point, as shown in figure 20,2 SS/PBCH block and its corresponding RMSI PDSCH just take all OFDM symbols in 1ms time window.In this way Can be to avoid occurring blank character in 1ms time window, the avoidable network equipment needs to send other downlink signals to fill sky White symbol.

For ECP, under other bandwidth and the scene of SCS, the symbol numbers that 1ms time window includes are different, actually answer The selection RMSI PDSCH that can be adapted in lasting symbolic number, avoids blank character occur in 1ms time window as far as possible.

It should be understood that when preset time position SS/PBCH block RMSIPDSCH corresponding with its (or its correspond to RMSI CORESET and RMSIPDSCH) due to LBT failure and when can not send, the network equipment is needed in next SS/PBCH The corresponding preset time position block could send not sent SS/PBCH block.Due to the RMSIPDSCH duration compared with It is long, it needs first to send other downlink signals when middle LBT of the network equipment 2 preset time positions is successful and occupies letter Road increases the complexity of system call and the access delay of UE.

In this regard, on the other hand the application additionally provides a kind of method for transmitting signals, main inventive thought can include: logical After crossing LBT, one or more sends the time location continuous adjacent of SS/PBCH block, and the SS/PBCH block is corresponding RMSI PDSCH (or the SS/PBCH block corresponding RMSI CORESET and RMSI PDSCH) continuously occupies multiple symbols Number.It is described in detail below by specific embodiment.

(4) example IV

Example IV kind, the network equipment can LBT success after flexibly send one or more SS/PBCH block and Its corresponding RMSICORESET and RMSI PDSCH (or only RMSI PDSCH), wherein RMSICORESET and RMSIPDSCH (or Only RMSI PDSCH) it can continuously be sent with corresponding SS/PBCH block, it can also discontinuously send.

In one possible implementation, as Figure 21 it is exemplary shown in, as only one SS/PBCH block and its is right When RMSICORESET and RMSI PDSCH (or the only RMSI PDSCH) joint answered is sent, the network equipment can be according to the knot of LBT Fruit starts to send the SS/PBCH block and corresponding RMSICORESET and RMSI PDSCH (or only in different character positions RMSI PDSCH).Illustrate several possible implementations below.The network equipment can be configured with optional in 1ms time window The corresponding preset time position 8 SS/PBCH block, position 1 be symbol 0-3, position 2 be symbol 4-7, position 3 be symbol Number 8-11, position 4 are symbol 12-15, and position 5 is symbol 16-19, and position 6 is symbol 20-23, and position 7 is symbol 24-27, position 8 are set as symbol 28-31.By the network equipment after LBT SS/PBCH can be sent in some above-mentioned optional preset time position block.The time index (time index) entrained by the SS/PBCH block that different character positions is sent is also different, To which terminal can carry out time synchronization by the time index of SS/PBCH block.However, due to net after LBT success Network equipment has little time to update the time index carried in SS/PBCH block, therefore the network equipment can prepare m before LBT A time index different SS/PBCH block, for example, above-mentioned position 1~8 can respectively correspond index0~7 time, In, m is the number for sending the preset time position of SS/PBCH block, and m is positive integer.The network equipment can be with after LBT success Being chosen according to the character position for sending SS/PBCH block, there is the SS/PBCH block of corresponding time index to be sent, The SS/PBCH block for being such as 0 in symbol 0-3 sending time index；Or the SS/ for being 8 is indexed in symbol 28-31 sending time PBCH block.After one SS/PBCH block of selection is sent, corresponding RMSICORESET and RMSI PDSCH (or only RMSI PDSCH) is sent next to the SS/PBCH block.

When the network equipment sends the corresponding RMSI CORESET of the SS/PBCH block next to the SS/PBCH block When with RMSI PDSCH, the indicating mode previous embodiment two (referring to the existing regulation in NR to PBCH) of PBCH；Work as network Equipment only sends the corresponding RMSI PDSCH of the SS/PBCH block next to the SS/PBCH block, without sending RMSI When CORESET, the indicating mode of PBCH can refer to previous embodiment one.

In alternatively possible implementation, as Figure 22 it is exemplary shown in, SS/PBCH block and RMSI CORESET and RMSI PDSCH is discontinuously sent, i.e. the corresponding RMSI of the occupied time-domain resource of SS/PBCH block The occupied time-domain resource of CORESET, RMSI PDSCH is discontinuous.At this point, the network equipment can be sent out in some after LBT success The preset time position of SS/PBCH block is sent to send SS/PBCH block.The corresponding RMSI of SS/PBCH block CORESET running time-frequency resource position can be indicated that the instruction is believed by 8 bit informations in the PBCH in SS/PBCH block Breath indicates the RMSI CORESET time domain occupied and frequency domain resource.In the present embodiment, RMSI CORESET default is in frequency Entire initial portions of bandwidth (initial BWP) is occupied on domain.Illustratively, the PBCH in SS/PBCH block can also refer to Show the start time position (such as primary sign) of more kinds of possible RMSI CORESET, the initial time position of RMSI CORESET Setting can be indicated or be calculated with reference to the first preset time position for sending SS/PBCH block.It should be noted that If the initial time that terminal when RMSI CORESET is not detected in the start time position that PBCH is indicated, can be indicated in PBCH Some specified time window after position persistently detects RMSI CORESET.Illustratively, this is used to detect RMSI The length of the time window of CORESET can preset (for example, being provided by standard agreement) or this is used to detect RMSI CORESET The length of time window can also be indicated by PBCH.In addition, RMSI CORESET can take entire initial on frequency domain The corresponding DMRS of BWP, RMSI CORESET can also take entire initial BWP on frequency domain, and broadband DMRS can be used for Terminal is assisted to carry out blind examination to RMSI CORESET.In the example of Figure 22, for sending the time location of SS/PBCH block The time location of corresponding RMSI CORESET and RMSI PDSCH is located in different time slots (1ms).Optionally, it is used for The time location for sending corresponding RMSI CORESET and the RMSI PDSCH of time location of SS/PBCH block can also be with In the same time slot (1ms).

When the network equipment using Figure 22 it is exemplary shown in mode send SS/PBCH block and its corresponding RMSI When CORESET and RMSI PDSCH, the indicating mode previous embodiment two (referring to the existing regulation in NR to PBCH) of PBCH. Moreover, the resource location of RMSI PDSCH needs RMSI CORESET to indicate, with specific reference in NR to RMSI CORESET's Existing regulation.

In another possible implementation, as Figure 23 it is exemplary shown in, when the network equipment is there are two SS/PBCH When block RMSICORESET and RMSI PDSCH corresponding with its (or only RMSI PDSCH) carries out joint transmission, that is, send Its corresponding RMSICORESET and RMSI PDSCH (or only RMSI can be and then sent after one SS/PBCH block PDSCH), another SS/PBCH block RMSICORESET and RMSI PDSCH corresponding with its is retransmited later (or only RMSI PDSCH).The network equipment can send the two SS/PBCH according to by the time of LBT on different symbols Block RMSICORESET and RMSI PDSCH corresponding with its (or only RMSI PDSCH).Wherein, RMSI PDSCH is persistently accorded with Number length can be the integral multiple of 4 symbols, for example 4,8 or 12 symbols.

When the network equipment next to SS/PBCH block send the corresponding RMSI CORESET of the SS/PBCH block and When RMSI PDSCH, the indicating mode previous embodiment two (referring to the existing regulation in NR to PBCH) of PBCH；When network is set It is standby only to send the corresponding RMSI PDSCH of the SS/PBCH block next to the SS/PBCH block, without sending RMSI When CORESET, the indicating mode of PBCH can refer to previous embodiment one.

In another possible implementation, as Figure 24 it is exemplary shown in, the network equipment first sends two SS/PBCH Block, it is corresponding next to the two SS/PBCH block are successively sent having sent second SS/PBCH block RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).In addition to the PBCH provided in embodiment one and embodiment two refers to Outside the method for showing the resource distribution of RMSI CORESET and the resource distribution of RMSI CORESET instruction RMSI PDSCH, SS/ PBCH also needs to indicate the number of SS/PBCH block for needing to continuously transmit in PBCH block and its is corresponding The configuration informations such as the lasting symbolic number of RMSICORESET and RMSI PDSCH (or only RMSI PDSCH), for ease of description, with Under be referred to as " the second configuration information ".When the network equipment does not send the corresponding RMSI CORESET of SS/PBCH block, PBCH also indicates the configuration informations such as the MCS of RMSI PDSCH in SS/PBCH block.Illustratively, in SS/PBCH block PBCH can be multiplexed 8 the second configuration informations of bit indication of RMSI CORESET, and other reserved ratios in PBCH also can be used It refers in particular to show the second configuration information.For example, SS/PBCH block occupies 4 symbols, and the network equipment sends 2 SS/PBCH altogether Block, it is assumed that network equipment LBT success before symbol 0, then this 2 SS/PBCH block occupy symbol 0-3 and symbol respectively Number 4-7.After terminal receives the 1st SS/PBCH block, know that the SS/PBCH block is occupied by time index Symbol 0-3, symbol 4-7 are occupied by the 2nd SS/PBCH block, therefore corresponding with the 1st SS/PBCH block The primary sign of RMSICORESET and RMSI PDSCH (or only RMSI PDSCH) is symbol 8, and terminating symbol is symbol x, x etc. In the lasting symbolic number -1 of 8+RMSICORESET and RMSI PDSCH (or only RMSI PDSCH)；Similarly, when terminal receives the 2nd When a SS/PBCH block, that is, it may know that RMSICORESET and RMSI PDSCH corresponding with the 2nd SS/PBCH block The primary sign of (or only RMSI PDSCH) is y, and y is equal to 8+RMSICORESET and RMSI PDSCH (or only RMSI PDSCH) Lasting symbolic number, terminating symbol z, z are equal to 8+RMSI PDSCH (or only RMSI PDSCH) lasting symbolic number * 2-1.According to This analogizes, 24 it is exemplary shown in method can extend to that continuously transmit multiple SS/PBCH block corresponding with its The scene of RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).

In another possible implementation, as Figure 25 it is exemplary shown in, the network equipment has 2 SS/PBCH block It needs to send with RMSI CORESET and the RMSI PDSCH for answering it, and SS/PBCH block RMSI corresponding with its CORESET and RMSI PDSCH is discontinuously sent.The network equipment can be in certain two continuous transmission SS/ after LBT success at this time The preset time position of PBCH block sends SS/PBCH block.RMSI CORESET running time-frequency resource position can be by SS/ 8 bit informations of PBCH are indicated in PBCH block, and the instruction information is to the RMSI CORESET time domain occupied and frequency domain The instruction that resource is distinguished.In the present embodiment, RMSI CORESET default occupies entire initial BWP on frequency band.SS/ PBCH in PBCH block also can indicate that the start time position of more kinds of possible RMSI CORESET, illustratively, The start time position of RMSI CORESET can be used for sending the position of SS/PBCH block with reference to preconfigured first The primary sign set perhaps terminating symbol or can be sent with reference configuration the SS/PBCH block time slot the 0th symbol To be indicated or be calculated.If it should be noted that the terminal initial time position that PBCH is indicated in SS/PBCH block Set when RMSI CORESET is not detected, can some specified time window after the start time position that PBCH indicate it is lasting Detect RMSI CORESET.Illustratively, the length of the time window for being used to detect RMSI CORESET can preset (for example, Provided by standard agreement) or the length of the time window for being used to detect RMSI CORESET can also be indicated by PBCH.This Outside, RMSI CORESET should take entire initial BWP, and the corresponding DMRS of RMSI CORESET also takes entirely at this time Initial BWP, broadband DMRS can be used for terminal and carry out blind examination to RMSI CORESET.In the example of Figure 25, for sending out The time location for RMSI CORESET and the RMSI PDSCH for sending the time location of SS/PBCH block corresponding is located at difference Time quantum (such as: time slot) in.Optionally, for sending the corresponding RMSI of the time location of SS/PBCH block The time location of CORESET and RMSI PDSCH can also be located in unit (such as: time slot) at the same time.

When the network equipment using Figure 25 it is exemplary shown in mode send SS/PBCH block and its corresponding RMSI When CORESET and RMSI PDSCH, the indicating mode previous embodiment two (referring to the existing regulation in NR to PBCH) of PBCH. Moreover, the resource location of RMSI PDSCH needs RMSI CORESET to indicate, with specific reference in NR to RMSI CORESET's Existing regulation.

By example IV, the network equipment can flexibly send one or more SS/PBCH block after LBT success And its corresponding RMSICORESET and RMSI PDSCH (or only RMSI PDSCH), wherein RMSICORESET and RMSI PDSCH (or only RMSI PDSCH) can continuously be sent with corresponding SS/PBCH block, can also discontinuously be sent, be provided More neatly transmission mode.

(5) embodiment five

In embodiment five, the network equipment sends block and n corresponding RMSI PDSCH of m SS/PBCH, wherein m > n, m, n are positive integers.And in the aforementioned embodiment, the network equipment sends m SS/PBCH block, and just corresponding transmission m is right The RMSI PDSCH answered.Embodiment five, which can be improved, sends SS/PBCH block, RMSICORESET and RMSI PDSCH (or only RMSI PDSCH) flexibility.

In one possible implementation, as Figure 26 it is exemplary shown in, the network equipment is configured with 8 in 1m time window A preset time position for sending SS/PBCH block.Illustratively, the preset time position of this 8 transmission SS/PBCH block It sets corresponding with 1 RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).When network equipment LBT success before symbol 0 When, 8 SS/PBCH block can be continuously transmitted in the preset time position, and behind last 1 preset time position closely Send corresponding RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).When the network equipment before symbol 12 LBT at When function, the network equipment can continuously transmit 5 SS/PBCH block, and next to hair behind last 1 SS/PBCH block Send corresponding RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).In conclusion network equipment meeting basis passes through The character position of LBT sends at least one identical SS/PBCH block and 1 corresponding RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).In this way, the network equipment LBT success after can continuously transmit several SS/PBCH block and 1 RMSICORESET and RMSI PDSCH (or only RMSI PDSCH) RMSICORESET and RMSI PDSCH (or only RMSI PDSCH it) is sent next to the last one SS/PBCH block, channel will not be occupied by other equipment.

In the present embodiment, RMSI PDSCH is only sent when the network equipment is located next to the last one SS/PBCH block, and When not sending RMSI CORESET, there are two types of PBCH indicating modes: 1) PBCH instruction continuously transmits SS/ in SS/PBCH block The number of PBCH block and the relevant configuration information of RMSI, such as the lasting symbolic number of RMSI PDSCH, MCS, DMRS configuration, 8 bits for being used to indicate RMSI CORESET that the network equipment can be multiplexed PBCH in SS/PBCH block are indicated, can also To use other reserved bits of PBCH in SS/PBCH block to be indicated.Terminal can be with according to SS/PBCH block information Corresponding RMSI PDSCH is found, and PDSCH decoding is carried out according to indicated configuration information.2) PBCH in SS/PBCH block The time-domain position for providing RMSI indicates that (instruction can be used for sending SS/PBCH block's with preconfigured first The primary sign of position either terminating symbol is reference point, or can be to configure the time slot for sending the SS/PBCH block The 0th symbol be reference point) and RMSI PDSCH configuration information, such as the lasting symbolic number of RMSI PDSCH, MCS, DMRS configuration etc..Above-mentioned instruction information can be multiplexed 8 bits that RMSI CORESET is used to indicate in PBCH, also can be used Other reserved bits in PBCH.Terminal is found according to above- mentioned information receives the corresponding RMSI PDSCH of SS/PBCH block simultaneously RMSI PDSCH decoding is carried out according to above-mentioned configuration information.

In the present embodiment, when the network equipment next to the last one SS/PBCH block send RMSI CORESET and RMSI PDSCH and when the two continuously transmits, i.e. RMSI PDSCH are when followed by RMSI CORESET is sent in the time domain.SS/ In PBCH block there are two types of the indicating modes of PBCH: 1) carrying the network equipment in PBCH and continuously transmit SS/PBCH block's The configuration information of number and RMSI CORESET, such as its lasting symbolic number or polymerization grade (aggregation level), The configuration information, which can be multiplexed in PBCH, indicates that 8 bits of RMSI CORESET are indicated, its in PBCH also can be used Its reserved bit is indicated.Terminal according to above- mentioned information find corresponding RMSI CORESET and according to above-mentioned configuration information into Row decoding further obtains the configuration information of RMSI PDSCH, such as persistently symbolic number, MCS, DMRS configuration etc., so as to solve Code simultaneously obtains the information in RMSI PDSCH.2) time-domain position that PBCH provides RMSI CORESET in SS/PBCH block refers to Show that (instruction can be used for sending the primary sign or knot of the position of SS/PBCH block with preconfigured first Beam symbol is reference point, or can be to configure the 0th symbol for sending the time slot of the SS/PBCH block as reference point) and The configuration information of RMSI CORESET, such as persistently symbolic number.Above-mentioned instruction information, which can be multiplexed in PBCH, is used to indicate RMSI Other reserved bits in PBCH also can be used in 8 bits of CORESET.Terminal finds corresponding RMSI according to the information CORESET and the configuration information that RMSI PDSCH is decoded and further obtained according to above-mentioned configuration information row, such as persistently symbol Number, MCS, DMRS configuration etc., so as to decode and obtain the system information in RMSI PDSCH.

In alternatively possible implementation, as Figure 27 it is exemplary shown in, SS/PBCH block RMSI corresponding with its The time-domain resource RMSI corresponding with its that CORESET and RMSI PDSCH separately send, i.e. SS/PBCH block occupy The time-domain resource that CORESET and RMSI PDSCH is occupied is discontinuous.Continuous multiple SS/s of the network equipment after LBT success at this time The block preset time position PBCH sends SS/PBCH block.RMSI CORESET running time-frequency resource position can be by SS/PBCH 8 bit informations in block PBCH are indicated, the time-domain and frequency-domain resource which occupies RMSI CORESET into The instruction of row difference.In the present solution, RMSI CORESET default occupies entire initial BWP on frequency band.In conclusion PBCH can indicate the start time position of more kinds of possible RMSI CORESET in SS/PBCH block.Optionally, RMSI The time location of CORESET can be used for sending the starting of the position of SS/PBCH block with reference to preconfigured first 0th symbol of the symbol time slot that perhaps terminating symbol or configuration send the SS/PBCH block is indicated or is counted It calculates).If the starting that terminal when RMSI CORESET is not detected in the start time position that PBCH is indicated, can be indicated in PBCH Some specified time window after time location persistently detects RMSI CORESET.Illustratively, this is used to detect RMSI The length of the time window of CORESET can preset (for example, being provided by standard agreement) or this is used to detect RMSI CORESET The length of time window can also be indicated by PBCH.In addition, RMSI CORESET should take entire initial BWP, at this time The corresponding DMRS of RMSI CORESET also takes entire initial BWP, and broadband DMRS can be used for terminal to RMSI CORESET carries out blind examination.In the example of Figure 27, the corresponding RMSI of time location for sending SS/PBCH block The time location of CORESET and RMSI PDSCH (or only RMSI PDSCH) is located in different time quantums (such as: time slot).It can It selects, corresponding RMSI CORESET and the RMSI PDSCH of the time location for sending SS/PBCH block (or only RMSI PDSCH) time location can also be located at the same time slot in.

In another possible implementation, as Figure 28 it is exemplary shown in, the network equipment LBT success after 4 send out The preset time position of SS/PBCH block is sent to continuously transmit 4 SS/PBCH block, and followed by transmission 2 is corresponding RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).SS/PBCH block and RMSICORESET and RMSI at this time PDSCH (or only RMSI PDSCH) is not one-to-one relationship, it is therefore desirable to SS/PBCH block couple is indicated in PBCH RMSICORESET the and RMSI PDSCH (or only RMSI PDSCH) answered.Have 2 kinds of possible indicating modes: 1) PBCH indicates SS/ The sum of PBCH block, the sum of RMSICORESET or RMSI PDSCH and SS/PBCH block are corresponding The corresponding relationship of RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).For example, when 8 SS/PBCH block are corresponding When 2 RMSICORESET and RMSI PDSCH (or only RMSI PDSCH), it can be preceding 4 SS/PBCH block the corresponding 1st A RMSICORESET and RMSI PDSCH (or only RMSI PDSCH), rear 4 SS/PBCH block are 2nd corresponding RMSICORESET and RMSI PDSCH (or only RMSI PDSCH)；It is 1st corresponding to be also possible to odd number SS/PBCH block RMSICORESET and RMSI PDSCH (or only RMSI PDSCH), even number SS/PBCH block correspond to the 2nd RMSICORESET With RMSI PDSCH (or only RMSI PDSCH).2) in order to save PBCH instruction expense, system only supports several possible reflect Mode is penetrated, all possible corresponding relationship can be provided by allocation list, and the illustrative allocation list can be provided by standard.PBCH refers to Show the index in the corresponding above-mentioned allocation list of currently used configuration, terminal is according to the instruction information and receives SS/PBCH block's Time index can find corresponding RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).

When the network equipment sends RMSI CORESET and RMSI PDSCH and two next to the last one SS/PBCH block When person continuously transmits, in SS/PBCH block there are two types of PBCH indicating modes: 1) carrying the network equipment in PBCH and continuously transmit SS/PBCH block number, RMSI CORESET and RMSI PDSCH lasting symbolic number and RMSI CORESET's matches confidence Breath, such as persistently symbolic number and SS/PBCH block correspond to the mapping relations of RMSI CORESET and RMSI PDSCH.This refers to Show that information can be multiplexed 8 bits of RMSI CORESET in PBCH and be indicated, other reserved ratios in PBCH also can be used Spy indicates.Terminal finds corresponding RMSI CORESET according to the instruction information and is decoded according to above-mentioned configuration information The configuration information of RMSI PDSCH, such as persistently symbolic number, MCS, DMRS configuration etc. are obtained, so as to carry out RMSI PDSCH Decoding obtain its carrying system information.2) PBCH provides time-domain position instruction (instruction of first RMSI CORESET The primary sign or terminating symbol for the position that SS/PBCH block can be can be used for sending with preconfigured first are ginseng Examination point, or can be to configure the 0th symbol for sending the time slot of the SS/PBCH block as reference point), RMSI CORESET The configuration information of lasting symbolic number and RMSI CORESET with RMSI PDSCH, such as persistently symbolic number.Above-mentioned instruction information 8 bits for being used to indicate RMSI CORESET in PBCH can be multiplexed, other reserved bits in PBCH also can be used.Terminal Corresponding RMSI CORESET is found according to the information and is decoded according to above-mentioned configuration information and is obtained RMSI PDSCH's Configuration information, such as persistently symbolic number, MCS, DMRS configuration etc., so as to decode and obtain the letter of the system in RMSI PDSCH Breath.

When the network equipment only sends RMSIPDSCH next to the last one SS/PBCH block, PBCH indicating mode has Two kinds: 1) carrying system continuously transmits reflecting for SS/PBCH block number and SS/PBCH block and RMSIPDSCH in PBCH The configuration information of relationship and RMSI PDSCH is penetrated, such as persistently symbolic number, MCS, DMRS configuration etc..The instruction information can be multiplexed It is used to indicate 8 bits of RMSI CORESET in PBCH, other reserved bits in PBCH also can be used.Terminal is according to the letter Breath finds corresponding RMSIPDSCH and is decoded according to above-mentioned configuration information.2) it is corresponding to provide the SS/PBCH block by PBCH RMSI time-domain position instruction (instruction can be used for sending the position of SS/PBCH block with preconfigured first Primary sign perhaps terminating symbol is reference point or can be to configure the 0th of time slot that sends the SS/PBCH block Symbol is reference point) and RMSI PDSCH configuration information, such as persistently symbolic number, MCS, DMRS configuration etc., it is also possible to including The mapping relations and system of SS/PBCH block and RMSIPDSCH send SS/PBCH block number.Above-mentioned instruction information can To be multiplexed 8 bits for being used to indicate RMSI CORESET in PBCH, other reserved bits in PBCH also can be used.Terminal root Find corresponding RMSIPDSCH according to the information and be decoded according to above-mentioned configuration information and obtain RMSIPDSCH carrying be System information.

Method shown in Figure 28 is exemplary, which can extend to, sends the multiple of SS/PBCH block and other quantity The scene of RMSICORESET and RMSI PDSCH (or only RMSI PDSCH).

In another possible implementation, as Figure 29 it is exemplary shown in, SS/PBCH block RMSI corresponding with its CORESET and RMSI PDSCH is individually sent, i.e. the time-domain resource of the two occupancy is discontinuous.The network equipment is in LBT success at this time The several preset time positions for sending SS/PBCH block of afterwards certain send SS/PBCH block.SS/PBCH block is corresponding RMSI CORESET running time-frequency resource position can by PBCH indicate RMSI CORESET 8 bit informations be indicated that this refers to Show the instruction that information distinguishes the time-domain and frequency-domain resource that RMSI CORESET is occupied.In the present solution, RMSI CORESET is silent Recognize and occupies entire initial BWP on frequency band.In conclusion when PBCH can indicate more kinds of possible RMSI CORESET (CORESET time-domain position can be used for sending SS/PBCH block's with preconfigured first to domain start time position Perhaps terminating symbol is reference point or can be to configure the time slot for sending the SS/PBCH block primary sign of position 0th symbol is that reference point is indicated or calculated).If terminal is not detected in the start time position that PBCH is indicated When RMSI CORESET, some the specified time window of meeting after the start time position that PBCH is indicated persistently detects RMSI CORESET.Illustratively, the length of the time window for being used to detect RMSI CORESET can be preset (for example, by standard agreement Regulation) or the length of the time window for being used to detect RMSI CORESET can also be indicated by PBCH.In addition, RMSI CORESET should take entire initial BWP, and the corresponding DMRS of RMSI CORESET also takes entire initial BWP at this time, Broadband DMRS can be used for terminal and carry out blind examination to RMSI CORESET.In the example of Figure 29, for sending SS/PBCH The time location position of corresponding RMSI CORESET and the RMSI PDSCH (or only RMSI PDSCH) of the time location of block In different time quantums (such as: time slot).Optionally, corresponding for sending the time location of SS/PBCH block The time location of RMSI CORESET and RMSI PDSCH (or only RMSI PDSCH) can also be located at unit at the same time In (such as: time slot).

By embodiment five, the network equipment can not sent correspondingly after LBT success SS/PBCH block and RMSICORESET and RMSI PDSCH (or only RMSI PDSCH) further improves the flexibility of system transmission.

In second of possible resource mapping method, the communication unit 501 in the network equipment 500 sends SS/PBCH The time location of block can not be the corresponding preset time position in the time window of specific length the SS/PBCH block It sets.SS/PBCH block is sent not at a fixed location.The especially suitable RMSI PDSCH's of the another kind implementation Payload is not enough to fill the time interval between two adjacent preset time positions in first time window (interval) the case where.

Correspondingly, the time location that the communication unit 403 in terminal 400 receives SS/PBCH block can not be the SS/ The corresponding preset time position in the time window of specific length PBCH block.SS/PBCH is received not at a fixed location block。

Specifically, being not enough to fill in the payload of RMSI PDSCH two adjacent default in first time window Under conditions of time interval (interval) between time location, the communication unit 501 in the network equipment 500 sends SS/ The time location of the corresponding RMSI PDSCH of PBCH block and the next SS/PBCH for sending the SS/PBCH block The time location continuous adjacent of block.

Correspondingly, the communication unit 403 in terminal 400 receives the time of the corresponding RMSI PDSCH of SS/PBCH block The time location continuous adjacent of next SS/PBCH block of position and reception the SS/PBCH block.

In the unfixed situation of time location for sending SS/PBCH block, when the communication unit 403 in terminal 400 Processing after detecting a SS/PBCH block, in addition to the time index (time index) that PBCH is carried, in terminal 400 Unit 401 also need according to the lasting symbolic number of RMSI PDSCH determine system-frame locating for system timing information index, It is synchronous to obtain Cell time for the index of the index of subframe, symbol.
