The application proposes a kind of detection method and device for controlling information, can reduce the complexity of terminal device blind examination, With reference to Fig. 4, this method comprises:

101: the network equipment sends configuration information to terminal device.

The network equipment can send configuration information to terminal device by RRC information, can also be sent out by other message Send configuration information, such as system information, broadcast message etc.；The process belongs to the prior art, is no longer described in detail.

It may include some configuration parameters in configuration information, such as be used to indicate the instruction letter of the SS block of actual transmissions Breath, is indicated with parameter SSB-transmitted, as shown in table 1 below:

Table 1

Upper table 1 be NR have agreed to using a parameter configuration, it is which indicates with the mode of a bitmap SSB's really transmits.Parameter SSB-transmitted is corresponding with different Bitmap length in different frequency range, i.e., different Frequency range (low frequency: including < 3GHz and 3-6GHz；High frequency: > 6GHz) length of bitmap is different；For example, there was only 4 in < 3GHz Bit only has the SSB wave beam of 4 actual transmissions in low frequency maximum.Need 8 bits in 3-6GHz, i.e., it is maximum only in 3-6GHz There is the SSB wave beam of 8 actual transmissions.And then have 64 bits in > 6GHz, i.e., high frequency maximum can permit using 64 wave beams into The transmission of row SSB.

Upper table is only illustrated, and may include more Bitmap length bit numbers, such as 16 bits, 32 bits, and 128 Bit, 256 can also use other numerical value than top grade, different frequency range bit numbers.

For example, there was only the SSB wave beam of 8 actual transmissions in 3-6GHz maximum if Bitmap length is 8 bits. Assuming that " 1 " represents the wave beam of actual transmissions, " 0 " represents the wave beam that reality is not transmitted, then SSB-transmitted value is When 11001100, the the 1st, the 2nd, the 5th, the 6th SSB wave beam actual transmissions are represented, the 3rd, the 4th, the 7th, the 8th SSB wave beam is real It does not transmit on border.When SSB-transmitted value is 11001100, the wave beam of a total of 4 actual transmissions.

102: terminal device receives configuration information and determines the bit length of wave beam instruction according to configuration information.

After terminal device receives configuration information, pass through the value of the Bitmap length of parameter SSB-transmitted Know the SSB number of beams of actual transmissions, and can also determine the information of frequency range.

Terminal device can determine the bit length of wave beam instruction according to the rule in following table 2.

Bitmap length of SSB-transmitted	Bit length of TCI in DCI
		4(<3GHz)	2bits
8(3-6GHz)	2bits
		64(>6GHz)	3bits
Reserved	Reserved

Table 2

In the citing of above table 2, when Bitmap length is 4 or 8, the bit length of wave beam instruction (TCI) is 2 bits, when Bitmap length is 64, wave beam indicates that the bit length of (TCI) is 3 bits.

As can be seen from the above table, less (4 or 8) in the whole wave beam number of low-frequency range (< 6GHz), it can deduce Wave beam suitable for some terminal device will not be too many, 2 than peculiar 4 states, enough terminal devices are safeguarded at low frequency can Use wave beam.Opposite, terminal can be deduced and set since wave beam overall number is possible more (64) at high band (> 6GHz) The standby wave beam number for needing to safeguard is also more；At this moment more bits are needed to carry out wave beam instruction, such as 3 than peculiar 8 shapes State at most can be used for safeguarding 8 available beams；Or with 4 bits, 16 available beams can be at most safeguarded.Therefore described The corresponding wave beam number of parameter is more, and the bit length of the wave beam instruction is longer.

Different frequency ranges can be embodied from the field length of SSB transmitted, and 4 bits or 8 bits correspond to low Frequently (<6GHz), 64 bits correspond to high frequency (>6GHz).Therefore, Bitmap length length is longer, indicates the wave beam of actual transmissions It is more, correspondingly, the bit number of the wave beam instruction needed is also more.

The value of Bitmap length corresponds to low-frequency range, and terminal device uses a fixed TCI bit number, such as 2 bits, It may be 0 bit, 1 compares top grade；The value of Bitmap length corresponds to high band, and terminal device also uses a fixed TCI Bit number, such as 3 bits, or 2 bits, 4-8 compare top grade；The TCI bit number that high frequency uses is greater than the TCI ratio that low frequency uses Special number.

According to upper table rule, if the Bitmap length of SSB-transmitted that terminal device receives is 4 ratios Special or 8 bits, then terminal device is known that communications band is low-frequency range (< 6GHz), thus may determine that wave beam instruction (TCI) Bit length be 2 bits；If the Bitmap length of SSB-transmitted that terminal device receives is 64 bits, Then terminal device is known that letter frequency range is high band (> 6GHz), thus may determine that the bit length of wave beam instruction (TCI) is 3 bits.

Therefore terminal device can determine band information according to the value of Bitmap length, the further ratio for determining TCI Bit length；Or the bit length of TCI can be directly determined according to Bitmap length.

Wave beam is designated as the TCI field in DCI in above-mentioned example, but is not limited to TCI field, can also use other words Section.

Only citing Bitmap length of SSB-transmitted is 4,8 or 64 to upper table, i.e., if SSB Transmitted value has more options, and upper table can be expanded accordingly, such as 16,32,128,256 etc., correspondingly, The length of TCI may be set to be 0-16 any number.

Upper table is to illustrate to provide the bit length of TCI, furthermore it is also possible to using similar method, but define with it is upper Different rules is stated, Bitmap length is bigger as long as meeting, and the bit number of TCI is more, such as the following table 3:

Bitmap length of SSB-transmitted	Bit length of TCI in DCI
		4(<3GHz)	0bits
8(3-6GHz)	2bits
		64(>6GHz)	3bits
Reserved	Reserved

Table 3

As can be seen that being 4 in the whole wave beam number of low-frequency range (< 3GHz), terminal available beams can at this time from upper table 3 It can only one, do not need individually to indicate, therefore TCI is 0 bit；It is 8 in 3-6GHz frequency range entirety wave beam number, can pushes away Measuring will not be too many suitable for the wave beam of some terminal device, it is assumed that up to 4,2 than peculiar 4 states, enough terminals Equipment safeguards available beams at low frequency.Opposite, at high band (> 6GHz), due to wave beam overall number possible more (64 It is a), terminal device can be deduced and need the wave beam number safeguarded also more, such as 8,16 etc.；At this moment it needs more Bit carries out wave beam instruction, if it is assumed that being 8, needs 3 bits；Assuming that 16 then need 4 bits.Therefore, the bit of TCI Number increases as Bitmap length length increases.

Other parameters can also be used in above-described embodiment, such as SSB-measured indicates the SSB for being used for actual measurement The instruction information of (SS block)；It only needs that SSB-transmitted is replaced with SSB-measured i.e. in the above example Can, no longer it is described in detail.

In addition, terminal device can determine the bit length of wave beam instruction according to the rule in following table X.

The SSB wave beam number of actual transmissions	Bit length of TCI in DCI
		0-16	0bits
16-32	1bits
		32-48	2bits
48-64	3bits
		Reserved	Reserved

Table X

In the citing of above table X, the SSB wave beam number of actual transmissions is bigger, and the bit length of wave beam instruction (TCI) is got over It is long.

Assuming that " 1 " represents the wave beam of actual transmissions, " 0 " represents the wave beam that reality is not transmitted, the SSB numbers of beams of actual transmissions Mesh is the number of " 1 " in this parameter of SSB-transmitted.Such as SSB-transmitted be 1100 when, actual transmissions SSB wave beam number when to be 2, SSB-transmitted be 11001100, the SSB wave beam number of actual transmissions is 4.

Alternatively, terminal device can determine the bit length of wave beam instruction according to the rule in following table Y.

Table Y

That is, the SSB wave beam number of actual transmissions is lower than 16, fixed setting TCI is 2 bits, the SSB numbers of beams of actual transmissions Mesh is greater than 16, and fixed setting TCI is 3 bits, naturally it is also possible to other numerical value be arranged, the present embodiment does not limit.

In above-mentioned example, the network equipment infers the bit long of wave beam instruction according to this parameter of SSB-transmitted Degree, it is illustrated below alternatively, it is also possible to determine the bit length of wave beam instruction according to other parameters.

The network equipment infers the TCI field length in DCI according to the other parameters in configuration information.

Other possible parameters, the relevant parameter including subcarrier spacing, such as RMSI-scs, SSB-scs； Numerology relevant parameter, such as DL-BWP-mu etc..

Such as: RMSI-scs refers to transmission remaining system message (remaining system information, RMSI) The subcarrier spacing (scs) used, its possible value and corresponding TCI field length are as shown in table 4 below:

RMSI-scs value	Bit length of TCI in DCI
		15(<6GHz)	2bits
30(<6GHz)	2bits
		60(>6GHz)	3bits
120(>6GHz)	3bits
		Reserved	Reserved

Table 4

In the citing of above table 4, RMSI-scs value is 15 or 30, indicates to be in low-frequency range (< 6GHz), can speculate Out will not be too many suitable for the wave beam of some terminal device, 2 are safeguarded at low frequency than peculiar 4 states, enough terminal devices Available beams, therefore the bit length of wave beam instruction (TCI) is 2 bits；When RMSI-scs value is 60 or 120, indicate In high band (> 6GHz), it is also more to deduce the wave beam number that terminal device needs to safeguard, at this moment needs more to compare Spy carries out wave beam instruction, and wave beam indicates that the bit length of (TCI) is 3 bits, can be used for safeguarding 8 available beams；Or With 4 bits, 16 available beams can be safeguarded.

Therefore RMSI-scs value is bigger, indicates that frequency range is higher, and wave beam indicates that bit needed for (TCI) is also more.

Similarly, SSB-scs refers to the scs that synchronous signal transmission block uses, its possible value and corresponding TCI field are long Degree such as the following table 5.

SSB-scs value	Bit length of TCI in DCI
		15(<6GHz)	2bits
30(<6GHz)	2bits
		120(>6GHz)	3bits
240(>6GHz)	3bits
		Reserved	Reserved

Table 5

When using SSB-scs parameter, judgment rule is similar with RMSI-scs, and SSB-scs parameter value is bigger, indicates frequency range Higher, wave beam indicates that bit needed for (TCI) is also more.As shown above, it is no longer described in detail.

In addition, DL-BWP-mu refers to the numerology of transmission bandwidth part, its possible value and corresponding TCI word Segment length such as the following table 6.

DL-BWP-mu value	Corresponding subcarrier spacing	Bit length of TCI in DCI
			0	15(<6GHz)	2bits
1	30(<6GHz)	2bits
			2	60(>6GHz)	3bits
3	120(>6GHz)	3bits
			4	240(>6GHz)	3bits
5	480(>6GHz)	3bits
			Reserved	Reserved	Reserved

Table 6

Numerology is parameter used by communication system.Communication system (such as 5G) can be supported a variety of numerologies.Numerology can be defined by the one or more in following parameter information: subcarrier spacing, circulation Prefix (cyclic prefix, CP), chronomere, bandwidth etc..For example, numerology can by subcarrier spacing and CP Lai Definition.CP information may include CP length and/or CP type.For example, CP can be normal CP (normal CP, NCP), or Person is extension CP (extended CP, ECP).The chronomere is used to indicate the time quantum in time domain, such as can be to adopt Sampling point, symbol, mini-slot, time slot, subframe or radio frames etc..Chronomere's information may include the type of chronomere, Length or structure etc..

As can be seen from the above table, when DL-BWP-mu value is 0-5, corresponding subcarrier spacing is followed successively by 15,30,60, 120,240,480；Low frequency (< 6GHz) is corresponded to when subcarrier spacing is 15,30, can be deduced suitable for some terminal device Wave beam will not be too many, 2 than peculiar 4 states, enough terminal devices safeguard available beams at low frequency, therefore wave beam indicates (TCI) bit length is 2 bits；High frequency (> 6GHz), terminal device are corresponded to when subcarrier spacing is 60,120,240,480 The wave beam number for needing to safeguard is also more, needs more bits at this moment to carry out wave beam instruction, wave beam indicates the bit of (TCI) Length is 3 bits, can be used for safeguarding 8 available beams；Or with 4 bits, 16 available beams can be safeguarded.

From above-mentioned table 1- table 6 and Table X, the parameters citing of Y can go out, and judgment rule is similar: if terminal Equipment receives parameter and corresponds to low-frequency range (< 6GHz), then TCI uses less bit, if terminal device receives parameter and corresponds to high frequency Section (> 6GHz), then TCI uses more bit, and frequency range is higher, and bit number is more, and wave beam instruction is longer；Or if terminal device is received Low-frequency range (< 6GHz) is corresponded to parameter, then TCI uses a fixed value, such as 2 bits, if terminal device receives parameter and corresponds to High band (> 6GHz), then TCI uses another fixed value, such as 3 bits, wherein the corresponding bit length of high band about low frequency The corresponding bit length of section.

The bit length of wave beam instruction in above-mentioned each table is only to illustrate, and can use other any numbers, such as exist Arbitrarily it is arranged in 0-16 bit.Above rule defined in each table can be provided by standard agreement, can not also be in standard agreement It is middle to provide but terminal device is sent to by the network equipment, such as terminal device is sent in configuration information, or by other Signaling issues terminal device.

In addition, terminal device can report the TCI field length of oneself preference to the network equipment, for example, terminal device can To report the ability of oneself by RRC signaling, wherein including the TCI field length of oneself preference, terminal is carried out to the network equipment After ability confirmation, it can use the length as the TCI field length in DCI, certain network equipment can also be without using eventually The TCI field length that end equipment reports, and oneself determines TCI field length.

103: the network equipment sends control information to terminal device.

The network equipment sends control information, such as DCI, belongs to the prior art, can be carried by PDCCH.

104: the bit length that terminal device is indicated according to determining wave beam detects control information.

The TCI length that terminal device is inferred to according to 102 is come to DCI progress blind examination.For example, terminal device is inferred to TCI Length is 3 bits, then a kind of hypothesis length that should use the length of 3+X as DCI carries out blind examination to PDCCH.Wherein X is DCI In other fields length sum.

Since the field length of TCI is it has been determined that therefore terminal device is only needed according to TCI field length determination DCI to control channel carry out blind examination, without the concern for TCI field length it is other a possibility that, therefore reduce blind examination time Number, detection efficiency improve.

Motion content is as follows in a standard for above scheme:

Note that here a non-fixed TCI bit width can be used for PDSCH beam indication.Depending on a different carrier frequency,environment,etc.,for example,beams in a higher frequency band may be narrower than beams in lower frequency band,the optimal number of beams used per UE may vary and a different TCI bit length can be considered.It can be realized even without an explicit higher layer signaling for the TCI bit length since UE can derive implicitly from other configured parameters during initial access or after RRC connection.For example,UE can assume 3-bit TCI if the bit length of higher layer parameter SSB-transmitted is 64,and assume a relatively shorter TCI length,e.g.,2bits,if SSB-transmitted is 4/8.

Proposal 4:Support UE to derive TCI bit length in DCI implicitly based on the higher layer configuration.

It is clearly proposed in above-mentioned motion, terminal (user equipment, UE) can be configured according to high-level signaling and be derived TCI bit length in DCI out.The parameter wherein used is SSB-transmitted.

The network equipment can send control information by PDCCH, and such as DCI gives terminal device, which belongs to existing skill Art is no longer described in detail.

202: terminal device determines the type of RNTI.

The configuration information that terminal device can be issued according to the network equipment determines that the type of RNTI, the process are existing skills Art is no longer described in detail.

There are many types by RNTI, and one is public RNTI, this is a kind of RNTI of user group property, usually may be SI- RNTI (system information RNTI, system message RNTI), P-RNTI (paging RNTI pages RNTI), RA- RNTI (PRACH RNTI, physical random access channel RNTI, Physical Random Access Channel RNTI) etc. One of RNTI.

There are also one is terminating stage RNTI, also referred to as UE-specific RNTI, such as C-RNTI, SPS-RNTI (semi- Persistent-scheduling RNTI, semi-continuous scheduling RNTI).

203: terminal device determines the bit length that wave beam indicates according to the type of determining RNTI.

As can be seen from the above table, if terminal device determine RNTI be public RNTI, such as: SI-RNTI, P-RNTI or RA-RNTI, usual terminal device can determine that wave beam indication bit length is 0, that is, not have TCI field；It may be other numbers Value, such as 1 bit, 2 compare top grade.

If the RNTI that terminal device determines is terminating stage RNTI, such as C-RNTI or SPS-RNTI, terminal device can be adopted With the solution of one embodiment, i.e. terminal device further determines that wave beam refers to according to some parameters in configuration information The bit length shown, specific method can refer to one embodiment, no longer be described in detail.

In addition, terminal device can also directly indicate wave beam if the RNTI that terminal device determines is terminating stage RNTI Bit length be set as a fixed value, such as 2 bits, or other numerical value, such as 3 bits, 4 bits, 5 than top grade number Value.

Upper table is only exemplary the bit length for providing TCI, can be used identical thinking but define with it is above-mentioned not Same rule.Upper table can not also provide in the protocol but be sent to terminal device in configuration information by the network equipment.

204: the bit length that terminal device is indicated according to wave beam detects control information or control channel.

The TCI length that terminal device is inferred to according to 202 determines the length of DCI, to carry out blind examination to DCI.With 104 It is similar, no longer it is described in detail.

In above-described embodiment, in step 203, if the RNTI that terminal device determines is public RNTI, TCI bit length It is 0.So when no wave beam indicates, terminal device needs to assume a default wave beam as wave beam is received, for not Same type RNTI, terminal device assume that different default wave beams.It is as shown in table 8 below:

RNTI type	Default wave beam
		(SI-)RNTI	Wave beam X
(P-)RNTI	Wave beam Y
		(RA-)RNTI	Wave beam W

The network equipment can configure SSB to the resource of wave beam management, do wave beam management to terminal device.The network equipment needs The information of the SSB of configuration is notified into terminal device, but existing protocol does not standardize how to configure SSB.It is introduced below several to match Set mode:

First way, the network equipment send configuration information to terminal device, include being used to indicate M in the configuration information The instruction information of the synchronization signal block SSB of a actual transmissions, and it is used to indicate the instruction letter of N number of SSB for wave beam management Breath, wherein the N is less than or equal to M, and N number of SSB is selected from the M SSB, wherein is used to indicate N number of for wave beam management The instruction information of SSB include relative numbering of the N number of SSB in M SSB.It, can be according to described after terminal device receives Relative numbering determines the SSB for being used for wave beam management.Wherein, it is used to indicate the instruction letter of the synchronization signal block SSB of M actual transmissions Breath is SSB-transmitted parameter, and above-mentioned relative numbering can carry in SSB-Resource.It is used to indicate N number of be used for The instruction information of the SSB of wave beam management can be SSB-Resource.

After terminal device receives above-mentioned configuration information, the SSB for being used for wave beam management can be determined according to relative numbering.

Citing is illustrated below:

The network equipment can be the number of the SSB of terminal equipment configuration actual transmissions by SSB-transmitted parameter, For SSB-transmitted parameter in above-described embodiment by the agency of mistake, it is which SSB is indicated with the mode of a bitmap Really transmit.There are many values, and for 64, SSB-transmitted is the bit diagram of 64 bits at this time, The expression that middle value is 1 is the SSB of actual transmissions, the SSB for the non-actual transmissions of expression that value is 0；Assuming that SSB- Having 16 values in 64 bits of transmitted is 1, for example, the bit diagram of SSB-transmitted show the 5,6, 7,8,18,19,20,21,41,42,43,44,54,55,56,57 } a bit value is 1, indicates that this 16 SSB are actual transmissions 's.

The network equipment can select a part from above-mentioned 16 SSB, such as: selection 4 therein, selection the 8,18, 41,54 } a SSB is that wave beam manages resource, this number of 4 SSB in 64 bits is 8,18,41,54 respectively；If directly will Above-mentioned number information is sent to terminal device, then needs to expend more bit resources, such as each SSB needs log₂(64) The resource of=6 bits is indicated.The corresponding wave beam of each SSB.

If 4 SSB that is, as wave beam management resource are used in 16 SSB of actual transmissions using relative numbering Relative numbering, then can save more bit resources.Above-mentioned { 8,18,41,54 } a SSB 5,6,7,8,18,19, 20,21,41,42,43,44,54,55,56,57 } number of the SSB of a actual transmissions is { 4,5,9,13 }, if compiled since 0 It is number then { 3,4,8,12 }, due to being up to 16, each SSB then only needs log₂(16)=4 the resource of bit, above-mentioned 4 SSB The bit number used is { 0011,0100,1000,1100 }.

The relative numbering of the SSB of wave beam management resource is sent to terminal device by the network equipment, and terminal device can be known Corresponding SSB.The information of relative numbering can carry in SSB-Resources；SSB-Resources also writes SSB- sometimes resource。

The motion of scheme mentioned above in a standard are as follows:

In addition,the details of the higher layer parameter ssb-Resources are still missing.Since UE can obtain the actually transmitted SS/PBCH blocks by the higher layer parameter SSB-transmitted,and the SS/PBCH blocks configured for beam management belong to a subset of actually transmitted SS/ PBCH blocks,a list of relative SSB indexes can provide UE enough information on the beam management resources,with each relative SSB index has a reduced bitwidth,where is the number of actually transmitted SS/PBCH blocks.

Proposal:Support to configure the SSB for beam management by a list of relative SSB indexes based on the higher layer parameter SSB-transmitted.

The second way: the network equipment sends configuration information to terminal device, includes being used to indicate M in the configuration information The instruction information of the SSB of a actual transmissions still further comprises the instruction information of at least 1 bit, the instruction of at least 1 bit Information is used to indicate the M SSB for wave beam management.After terminal device receives, it can be determined and be used according to 1 bit indication information In the SSB of wave beam management.The bit information of other quantity can of course be used, mainly indicates that the SSB of M actual transmissions is used Make the SSB of wave beam management.

The network equipment can all configure the SSB of above-mentioned actual transmissions to the resource of wave beam management, can be in SSB- It is indicated in Resources with the instruction information of 1 bit, by taking the SSB of above-mentioned 16 actual transmissions as an example, if the bit It is 1, then it represents that the SSB of 16 actual transmissions is each configured to the resource of wave beam management；If the bit is 0, then it represents that wave beam pipe There is no SSB in the resource of reason.The instruction information of 1 bit can carry in SSB-Resources.

The third mode: the network equipment sends configuration information to terminal device, includes being used to indicate M in the configuration information The instruction information of the synchronization signal block SSB of a actual transmissions；And the instruction information of M-bit, N number of SSB is used to indicate for wave Beam tube reason, wherein N is less than or equal to M, and N number of SSB is selected from the M SSB.Wherein N number of bit in M-bit wave beam instruction information When taking 1, indicate this N number of SSB for wave beam management；The SSB of wave beam management is indicated when 0 can of course be set as taking. After terminal device receives, it can indicate that information determines the SSB for being used for wave beam management according to the M-bit.The instruction of M-bit is believed The instruction information of breath can carry in SSB-Resources.

The mode that bitmap also can be directly used in the network equipment indicates the resource of wave beam management, still with above-mentioned practical biography For 16 defeated SSB, the relative numbering in 16 SSB of 4 SSB picked out is { 4,5,9,13 } a SSB, with than Special figure is designated as { 0001100010001000 }, i.e., { 4,5,9,13 } a bit value is 1, and other values are 0.This instruction Mode simple, intuitive.

M, N are integer in above-mentioned each embodiment.

The cell number of SSB, SSB carrier index, SSB can also be carried in above-mentioned each embodiment in ssb-Resource At least one information such as BWP (bandwidth part) number.It further, can also include other cell/carrier/BWP SSB-transmitted etc., the wave beam management resource of other cell/carrier/BWP can also carry out using above-mentioned several ways Instruction, and carry in SSB-Resources, other cells can be adjacent cell, that is to say, that adjacent cell is used for wave beam The SSB of management can also be indicated in fashion described above, and be carried in SSB-Resource.

Above- mentioned information can also carry in other fields of configuration information, be not limited to SSB-Resources.；With confidence Breath can be sent by the layer two of terminal device or the signaling of layer three, such as MAC (Media Access Control, media Access control) layer signaling or rrc layer signaling.

After terminal device receives downlink signal (such as CSI-RS, SSB) information that the network equipment is sent, need to the network equipment Corresponding downlink signal information is fed back, such as: CRI (CSI-RS resource indicator, CSI-RS resource instruction) is used In the number of instruction CSI-RS；SSB index is used to indicate the number of SSB；If configuration CSI-RS number of resources and The number of resources of SSB is identical, then terminal device will use same bits length and be fed back, then the network equipment cannot be distinguished on earth What is reported is which type of downlink signal.

Just like giving a definition in standard:

is the number of CSI-RS resources in the corresponding resource set,and is the configured number of SS/PBCH blocks in the corresponding resource set for reporting‘SSB/RSRP’。

It is quantity of the CSI-RS resources in corresponding resource set,It is that SS/PBCH blocks exists The quantity that respective resources are concentrated.Above-mentioned resource is by network equipments configuration.

CSI-RS, SSB are also referred to as reference signal by some documents, they are divided into reference signal and same by some documents Signal is walked, they are all downlink signals.

To solve the above problems, set forth below is three kinds of reporting schemes:

After terminal device receives downlink signal, feeding back downlink signal message is to the network equipment, in the downlink signal information It is numbered including downlink signal, still further comprises the instruction information for indicating the downlink signal type.Such as:

(or rear) adds 1 bit to indicate the type of CRI before the bit of mark CRI, such as: value is that " 1 " indicates this The corresponding signal type of a number is CRI (or CSI-RS).

The type of 1 bit indication SSB of (or rear) addition before the bit of mark SSB index, such as: value is " 0 " table Showing that this numbers corresponding signal type is SSB index (or SSB).

Indicate that the bit position of CRI or SSB type can arbitrarily be set, value also can be set, and use 0 indicates CRI, with 1 Indicate that SSB index can also be with.It, can be according to 1 ratio after the downlink signal that the network equipment receives terminal device feedback in this way is numbered Which kind of type what special type indication information determined the corresponding signal of the number is, such as SSB or CSI-RS.Certain type instruction letter Breath is not limited to 1 bit, can be other quantity.

In addition, the number of SSB or CSI-RS can report together, different message fields is occupied, the network equipment is same Sample can be distinguished according to type indication information.

One SSB or CSI-RS usually corresponds to a wave beam, therefore available following scheme:

Terminal device feeds back beam information to the network equipment, includes that wave beam is numbered in the beam information, also further packet Include the instruction information that instruction wave beam numbers corresponding downlink signal type.

Downlink signal may include that SSB and/or CSI-RS, above-mentioned SSB and CSI-RS can correspond to different wave beams, can also With the identical wave beam of correspondence.

The motion of scheme mentioned above in a standard are as follows:

According to previous achieved RAN1agreements and currently endorsed specifications,both SSB and CSI-RS can be configured as the resources for L1- RSRP computation.For beam reporting,local beam index is used.For example,the bitwidth for CRI in beam reporting is where is the number of CSI-RS resources in the corresponding resource set,and the bitwidth for SSB index in beam reporting is where is the configured number of SS/PBCH blocks in the corresponding resource set.If equals to,gNB may not be able to distinguish whether the beam reported is corresponding to a CSI-RS resource or a SSB resource.To avoid this ambiguity,one more bit can be added to the beam reporting to differentiate the RS types.

Proposal:Support beam reporting with one bit to differentiate the RS types.

In another scheme, can also by reference signal information (CSI-RS resource quantity) and synchronization signal Information (SSB resource quantity) as a set, it is numbered on the whole, i.e., no matter CRI or SSB index is usedThe bit of bit length indicate.

For example, can incite somebody to actionBefore setA element,After setA element, Vice versa.That is: terminal device feeding back downlink signal message is to the network equipment, and wherein a part of bit of downlink signal information is used In instruction reference signal (CSI-RS), another part bit is used to indicate synchronization signal (SSB).It, can also after the network equipment receives Determine which bit is CSI-RS with the rule according to setting, which bit is SSB.For example, first half bit is CRI, use In instruction CSI-RS；Latter half bit is SSB index, is used to indicate SSB, and vice versa.

In some documents, CSI-RS, SSB can also be referred to as reference signal.

In another scheme, when CRI and SSB index together on give the correct time, abandon one of them, such as:

Agreement regulation, the reporting of CRI > SSB index are reported.For example, first reporting CRI, SSB index is then reported, Or SSB index is abandoned, only report CRI.That is priority of the priority of CSI-RS greater than SSB.

The signaling format that specific terminal device reports is UCI (uplink control information, upload control Information), it can be carried by uplink control channel or uplink data channels.It is also possible to the layer two or layer three of terminal device Signaling, i.e. MAC layer signaling or rrc layer signaling, are carried by uplink data channels.
