Description

Information processing method and device, network side equipment and terminal

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information processing method and apparatus, a network side device, and a terminal.

Background

In the high frequency technology research, in order to solve the problem that SSB (synchronization signal block) may not be transmitted due to LBT (listen before talk) of unlicensed spectrum, a technical method (i.e., a data burst block transmission window) of DBTW is introduced in the high frequency unlicensed spectrum technology discussion. However, in some scenarios, the base station may transmit the SSB directly without LBT, and in this case, the base station and the terminal operate in the non-DBTW mode, which may bring some additional benefits, such as: some spectrum is unlicensed in some regions and licensed in others, and regions designated as licensed spectrum do not need LBT; such as: in a region or some time periods, the base station considers that LBT is not needed to directly send SSB, and LBT is needed before SSB is sent in some time periods. However, in the prior art, the transmission of the SSB always operates according to the DBTW, which results in resource waste; whereas if a bit is added to indicate the DBTW, the existing scheme is significantly altered and difficult to implement.

As can be seen from the above, the information processing scheme for the DBTW enabled state in the prior art has the problems of resource waste, high implementation difficulty, and the like.

The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of root antenna combinations.

The following first introduces the contents related to the scheme provided in the embodiments of the present application.

Content 1. Transmission technique for SSB (synchronization signal block) in nru (New radio operation on unlicensed spectrum, NR);

in an unlicensed spectrum, in order to effectively support the transmission of SSBs and alleviate the problem caused by the failure of SSBs due to LBT (listen before talk) failure, the NRU adopts an SSB cyclic shift method, that is, in one data transmission window, the system designs more SSBs candidate transmission positions (for example, actually transmit 4 SSBs and set 10 SSBs candidate positions), allocates multiple transmission opportunities to each SSB, and when the SSBs cannot be transmitted on the first transmission opportunity due to LBT failure, the base station has a chance to transmit the SSBs on the second transmission opportunity.

The operation method of DBTW (data burst transmission block) in NRU is explained below with SCS =15KHz and the operating frequency below 3 GHz:

the first step is as follows: expanding the number of candidate locations for SSB (extending from 4 candidate locations to 10);

the second step: by means of a parameter Q (which is used to indicate the QCL quasi co-location relationship between SSB candidate locations, also called in the existing standard

) And calculating SSB index (index number of actual SSB) by detecting candidate SSB index (SSB candidate position index, i.e., SSB candidate index). The calculation method comprises the following steps: SSB index = mod (candidate SSB index, Q).

Wherein: the Q parameter indicates the number of SSBs with the largest possible transmission, and indicates the association with a parameter in PBCH (e.g., kssb association in NR, where Kssb is the difference between the starting position of the resource block RB and the starting position of the control channel RB representing the SSB), when the parameter is odd, Q is 2, and when the parameter is even, Q is 1; the candidate SSB index is also indicated in PBCH and will not be described herein. Mod denotes the remainder.

Specifically, Q =2, there are 10 candidate SSB locations, and the calculation method is: SSB index = mod (candidate SSB index, 2). As shown in fig. 2: when the working frequency spectrum is less than 3GHz, each SSB has 5 sending candidate positions, and in an SSB sending window, the SSB has an opportunity to be sent as long as LBT is successful.

In the NRU, the unlicensed spectrum in which it operates always needs to perform LBT before transmitting the SSBs, so the terminal always defaults that the transmission of the SSBs operates according to DBTW.

Content 2. Adding 1bit in PBCH (physical broadcast channel) indicates that DBTW is enabled or disabled.

The

above contents

1 and 2 have the following disadvantages:

in content 1: the terminal always defaults that the transmission of the SSB is operated according to DBTW. This is reasonable on low frequency spectrum less than 7GHz, since on lower unlicensed spectrum LBT always needs to be performed before the base station sends the SSB.

On the unlicensed spectrum in the high frequency band, there are some cases where SSB is directly transmitted without LBT (e.g. 1: some regions these spectra are defined as licensed spectrum; e.g. 2: some regions and/or time-free LBT, e.g. 3, the transmission duty cycle of SSB is less than 10% LBT free), if the terminal operates according to DBTW in these scenarios, there are two drawbacks:

constraint on cell synchronization signal deployment: as described above, the DBTW windowing technique requires the base station to indicate the Q parameter, using the associated Kssb parameter. For the scenario that the SSB can be transmitted without LBT, the base station must also indicate the Q parameter so that the terminal can correctly calculate the actually transmitted index number of the SSB.

2: wasting air interface resources: for DBTW operation, the terminal assumes that SSB data is transmitted at all SSB candidate locations indicated by the base station. Such as: for the SCS =15KHz scenario of SSB, the candidate locations for SSB extend to 10. Even if the base station only transmits 1 SSB, the terminal needs to assume candidate positions of the 10 SSBs, and all the SSBs are likely to be transmitted. Namely; when the base station schedules the physical downlink shared channel PDSCH of the terminal and physical resource block PRB resources of the candidate SSB position to have overlap, the terminal considers the PRB resources as unavailable.

In content 2: adding 1bit in PBCH to indicate DBTW enablement or disablement would increase PBCH overhead, and the information that can be used specifically is only 1bit reserved bit (the reserved 1bit reserved bit would not be used in general), and if the bit is added newly, it would make a great change to the existing physical layer reception process.

Content 3. For the synchronization signal block SSB (SS/PBCH block, synchronization signal and PBCH block);

as shown in fig. 3, in an SSB structure of NR (new air interface), an SSB (synchronization signal block) includes PSS (primary synchronization signal), SSS (secondary synchronization signal), and PBCH, where PSS is a primary synchronization signal, SSS is a secondary synchronization signal, PBCH is a physical broadcast channel, and besides PBCH is a symbol behind PSS and SSS, PBCH also has data of PBCH at both ends of SSS; when searching for a cell, the UE performs synchronization search according to the PSS and/or the SSS, and receives a Physical Broadcast Channel (PBCH) after completing the synchronization search.

Content 4. Candidate locations for SSB transmission;

in the high frequency technology of NR (new air interface) evolution, SSB with subcarrier spacing SCS =120KHz is agreed to be supported, and the SSB structure is consistent with the existing NR technology. Candidate positions for SSB with current SCS =120KHz (0.25 ms) are shown in fig. 4:

when the subcarrier spacing SCS is 120kHz, the first symbol position index sent by the SSB in a 5ms period is: {4,8,16,20} +28 × n, n =0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18.

Content 5. Data transmission method for LBT exemption:

agreement in high frequency technology: when the node sends short control signaling (short control signaling), the node can avoid LBT direct sending, and the short control signaling is characterized in that: within a certain transmission period (e.g. 100 ms), the duty ratio is less than 10%, i.e. the transmission time is less than 10ms.

Content 6. Regarding the cell cellgarred parameter (cell barring access restriction parameter) in the MIB:

(1) A parameter (1-bit length) of cellgarred is included in a MIB (master information block) in the existing PBCH. Cellgarred is used to indicate whether the cell allows access or terminal camping.

1) As indicated: barred (e.g. 0 or 1) is forbidden, which means that the terminal is forbidden to park or access;

2) As indicated: a notbarred is not prohibited (e.g., is 1 or 0), indicating that the terminal is allowed to camp on or access.

(2) The parameter associated with cellgarred is intrafreq reselection (intra-frequency cell selection indication), and the parameter is used for whether the terminal is allowed to select a cell on the same frequency when cellgarred is indicated as barred.

1) If the indication is allowed (e.g. 0 or 1), it indicates that the terminal is allowed to perform cell reselection again on the same frequency;

2) If the indication is notAllowed (e.g. 1 or 0), it indicates that the terminal is not allowed to perform cell reselection again on the same frequency;

it should be noted that: (1) When notbarred is indicated in the MIB, the terminal starts to receive other broadcast messages, and the terminal may re-determine that the cell is barred according to other broadcast messages. If the current cell is judged to be barred, the terminal needs to determine a co-frequency cell selection strategy according to intraFreqReselection in the MIB message.

(2) When intraFreqReselection indicates notAllowed, its main purpose is to reduce unnecessary cell search procedure and selection procedure for the terminal. If the terminal continues to search for the cell on the same frequency, only a proper cell is found, and the fatal problem on the function can not be caused.

Based on the above, embodiments of the present application provide an information processing method and apparatus, a network side device, and a terminal, so as to solve the problems that in the prior art, an information processing scheme for a DBTW enabled state wastes resources and is difficult to implement. The method, the device, the network side equipment and the terminal are based on the same application concept, and because the principles of solving the problems of the method, the device, the network side equipment and the terminal are similar, the implementation of the method, the device, the network side equipment and the terminal can be mutually referred, and repeated parts are not repeated.

The information processing method provided in the embodiment of the present application is applied to a network side device, and as shown in fig. 5, includes:

step 51: determining target indication information corresponding to the first information according to the target corresponding relation and the first information;

step 52: sending the target indication information to a terminal; wherein the target correspondence includes at least one of: defining a first corresponding relation between first type indication information corresponding to the field and first information; a second corresponding relation between the first information and second type indication information corresponding to the updated defined field; before updating, the defined field corresponds to third type indication information; a third correspondence between the cell identification information and the first information; the cell identification information comprises parity information and/or affiliated group information of cell identification; the cell identification comprises primary synchronization signal PSS sequence information, secondary synchronization signal SSS sequence information and at least one of cell identifications obtained according to the PSS sequence information and the SSS sequence information; filling a fourth corresponding relation between a first field of a preset value and the first information in the master information block MIB on the unlicensed spectrum; wherein the first information comprises data burst transport block, DBTW, enabled state information; the defined fields are carried in the physical broadcast channel PBCH and/or the master information block MIB.

The third correspondence is to associate the first information with the cell ID.

In the following, the information processing method provided in the embodiment of the present application is illustrated, and a network side device takes a base station as an example.

In order to effectively inform the terminal DBTW enabled state, particularly, effectively inform the terminal DBTW enabled state (enabled or disabled) without increasing overhead of the physical broadcast channel PBCH and/or the master information block MIB extra information bit (bit); the embodiment of the application provides an information processing method, which mainly relates to the following steps:

operation 1: determining state (enable/disable) information of the DBTW using existing indication information carried in the PBCH and/or the MIB; the determination method includes at least one of the following two options:

option 1: associating existing indication information (without changing the use and meaning of the original field); the target corresponding relation comprises a first corresponding relation between first type indication information corresponding to a defined field and first information;

Option 2: indicating the original PBCH and/or the information of the MIB in the SIB (corresponding to option 2 in operation 1, i.e. moving the content originally indicated in the MIB and/or the PBCH (corresponding to the third type indication information mentioned above) to the SIB message, corresponding to indicating the third type indication information in the system information block SIB in case the target indication information is determined according to the second correspondence and the first information

In the embodiment of the application: the SIB message may be configured to the UE in SIB1 or other SIB messages, or through RRC signaling, which is not limited herein.

Specifically, the scheme provided by the embodiment of the application comprises the following scheme:

case 1 (determined from the SSB candidate index: corresponding to option 1 in

operations

1 and 2 above):

operation (1): preliminarily determining the state (enable or disable) of the DBTW from the "SSB candidate index (SSB candidate index)";

1) If the SSB candidate index satisfies condition 1 (e.g., 55 or less, condition 1 corresponds to the first condition described above), then the DBTW is considered disable;

SSB index in this case; calculated directly from the SSB candidate index (see the following example for details).

2) If the SSB candidate index does not satisfy condition 1 (e.g., is greater than 55), then DBTW is considered to be enable;

the SSB index in this case is determined by Q and SSB candidate index (see the following example).

Further optionally, operation (2): in the SIB message (as SIB 1), the status of DBTW is indicated:

if the SSB candidate index does not satisfy the condition 1 in the SSB data transmitted by the base station, the base station indicates the status of DBTW in the SIB message.

For a receiving end (namely UE), when the state indication of the DBTW received from the SIB is different from the state acquired from the MIB message, the content indicated by the SIB message covers the result judged by the UE from the MIB message.

Case 2 (determine from intrafreqReselection information in the MIB (redefined this information): option 2 in

operations

1 and 2 above):

operation (1): determining the state (enable or disable) of the DBTW according to the intraFreqReselection (whether the intra-frequency cell selection is allowed) in the MIB message; the determination method comprises the following steps:

1) When cellBarred in MIB indicates "notbarred" (indicating cell access is allowed, in which case intrafreq reselection is temporarily disabled):

if intraFreqReselection is 0, the DTBW is considered to be enabled, otherwise, disable (or vice versa); when the cellBarred parameter corresponding to the cell forbidden access restriction in the MIB indicates that the cell access is allowed and the intraFreqReselection information indicates a first value, enabling the DBTW enabling state information; and when the cell barred parameter in the MIB indicates that cell access is allowed and the intraFreqReselection information indicates a second value, the DBTW enabled state information is disabled.

2) Otherwise, when cellBarred in MIB indicates "barred" (indicating no cell access is allowed):

the terminal directly exits the access process; the DTBW status is not of interest.

Further optionally, operation (2): indicating the original information of intrafreq reselection in SIB (such as SIB 1) message; the terminal reads other SIB messages and judges whether the cell is barred or not according to the other SIB messages;

if the current cell is barred, the terminal determines the cell reselection measurement according to intraFreqReselection indicated by SIB;

otherwise (if not barred, the terminal ignores the intrafreq reselection indication of SIB indication (i.e. this field is not useful for UEs that are not barred).

In the embodiment of the application: for the high-frequency unlicensed band, if the unlicensed band is judged to be barred in operation (2), the terminal may also perform cell reselection measurement (e.g., allowed or not allowed) according to a default value of intrafreq reselection, or still perform cell reselection measurement according to the indication of the MIB (i.e., make a cell reselection policy).

The scheme provided by the embodiments of the present application is illustrated below.

Example 1 (determined from the SSB candidate index: corresponding to option 1 in

operations

1 and 2 above):

step 1: preliminarily determining the state (enable or disable) of the DBTW from the "SSB candidate index (SSB candidate index)";

in this example, it is assumed that when the base station transmits the SSB set, a part of the SSBs is allowed to be directly transmitted without LBT (for example, a part of the SSBs uses the rule of short control signaling and directly transmits without LBT), and the other part of the SSBs needs to perform SSB; as shown in fig. 7:

assuming that the base station determines that in the transmitted SSB set, if the number of SSBs transmitted is less than a value N1 (e.g. 56), the base station is LBT-free, and the SSB index and the candidate location index are one-to-one, i.e. the index of the candidate location can directly calculate the index of the SSB.

Then in this case: condition 1 may be "when the corresponding SSB candidate position index is detected to be less than or equal to a certain value N0 (e.g., assuming that the index starts from 0 and corresponds to N0= N1-1)";

when the UE is receiving the SSB, if the SSB candidate index satisfies the condition 1, the DBTW is considered to be disabled; the terminal calculates the SSB index according to the method that the state of the DBTW is disable, for example: SSB index = SSB candidate index;

when the UE is receiving the SSB, if the SSB candidate index does not satisfy the condition 1, it considers DBTW to be enable, and the terminal calculates the SSB index according to the method that the status of DBTW is enable, for example, as follows:

ssbinder = mod (SSBcandidate index-N1, Q) + N1, where mod () represents the remainder, N1=56, Q is an integer (e.g., Q = 8).

Wherein, 1: the method for calculating the SSB index is an example, and is used to explain that when the DBTW has different states, the method for acquiring the PBCH is different, and is not limited.

2: another expression of condition 1 may be: if a certain bit (for example, the highest bit) of the SSB candidate index is 1, the DBTW state is enabled, otherwise, the DBTW state is disabled. Such as: the SSB candidate index indicates "abcdefg" by 7 bits, the highest bit is "a", the DBTW state is considered to be enabled when a is 1, and the DBTW state is considered to be disabled when a is 0.

Step 2 (optional step): indicating a status of the DBTW in the SIB message;

in step 1, in the SSB set sent by the terminal, there is an SSB that needs to be LBT, and since the UE has a different location or a different beam direction, the terminal may receive only the SSB that satisfies condition 1, and after the UE acquires an SIB (system information block, which is different from the MIB), the indication needs to be refreshed. Specifically, the method comprises the following steps:

a base station side: the status of DBTW may be indicated in a message of SIB1 (numbered SIB 1), such as: DBTW _ flag ENUMERATED { true }. The message is defined as an enumeration type, and the UE use method is as follows:

the UE side: if the DBTW _ flag indication enable is resolved in SIB1, it is considered that processing is enabled according to the DBTW state during data reception (see the following processing 1), otherwise processing is disabled (see the following processing 2);

process 2 (DBTW state disable):

the UE determines the number (such as N) of SSBs sent by the cell and corresponding N candidate positions according to the indication of the SIB message;

when the terminal receives PDSCH (downlink shared channel) data scheduling, if the frequency domain Positions (PRBs) of the scheduled PDSCH and the frequency domain Positions (PRBs) of the above N candidate positions overlap, the terminal considers these overlapping PRB resources as unavailable (i.e., PDSCH data is not transmitted).

Treatment 1 (DBTW state enabled):

the UE determines, according to the indication of the SIB message, the number (e.g., N) of SSBs sent by the cell, and M candidate locations corresponding to the N SSBs, where M is greater than N.

When the terminal receives PDSCH data scheduling, if the frequency-domain Positions (PRBs) of the scheduled PDSCH and the above-mentioned M positions overlap, the terminal considers these overlapping PRB resources as unavailable (i.e., PDSCH data is not transmitted).

Here, it is explained that: here, the method for determining that PDSCH PRB resources are unavailable is used to describe that when the DBTW is in a different state, the method for acquiring PBCH information is different, which is only illustrative and not limiting.

Example 2 (determined from intrafreqReselection information in the MIB: corresponding to option 2 in

operations

1 and 2 above):

step 1: determining the state (enable or disable) of the DBTW according to the' intraFreqReselection (whether the intra-frequency cell selection is allowed) in the MIB message, and executing different actions according to the determined state information;

specifically, (1) a method of determining the DBTW-form may be as follows:

1) When cellBarred in MIB indicates "notbarred" (indicating that cell access is allowed, in which case intrafreq reselection is temporarily disabled): the UE reads intraFreqReselection information in the MIB;

if intraFreqReselection is 0, DTBW is considered to be enabled, otherwise disable (or vice versa).

the terminal directly exits the access process without paying attention to the DTBW state.

Wherein: the value of intrafreqReselection can be represented directly by the

binary value

0 or 1, or can be represented by other constants such as allowed or not allowed.

(2) According to the state enable or disable of the DBTW, the following different steps are performed:

1) The method for determining the SSB index when the DBTW is disable comprises the following steps: the terminal calculates the SSB index according to the method that the state of the DBTW is disable, for example: SSB index = SSB candidate index;

2) The method for determining the SSB index when the DBTW is enable comprises the following steps: the terminal calculates the SSB index according to the method that the state of the DBTW is enable, for example, as follows:

ssbinder = mod (SSBcandidate index, Q), where mod () represents the remainder, Q is an integer (e.g., Q = 64), and Q represents the upper limit of the number of SSBs actually transmitted in the DBTW window.

Wherein 1: the method for calculating the SSB index is an example, and is used to illustrate that, when the DBTW has different states, the PBCH information may be acquired by different methods, which is not limited.

Step 2 (optional step): information indicating intrafreqReselection in the SIB message;

since the original meaning (i.e. original information) of intrafreq selection is modified in step 1, in the SIB message, the base station can re-indicate the content (i.e. original meaning) of intrafreq selection, such as the status is allowed or not allowed; the terminal reads the message as needed. The process can be as follows:

a base station side: the original information of intrafreqReselection is indicated in the SIB message (e.g. SIB 1), and the value is allowed or not allowed or other status.

A terminal side:

the terminal reads other SIB messages and judges whether the cell is barred or not according to the other SIB messages (see the existing mode);

if the cell is judged to be barred, the terminal determines a cell reselection strategy according to intraFreqReselection indicated by the SIB; if the current cell is barred, the terminal determines the cell reselection measurement according to intraFreqReselection indicated by SIB;

Here, it is explained that:

1: for the high-frequency unlicensed band, if the determination in step 2 is barred, the terminal may also perform cell reselection measurement (e.g., allowed or not allowed) according to a default value of intrafreq reselection; or the cell reselection strategy is carried out according to the indication in the MIB.

2: the cell reselection strategy is as follows:

if the intrafreq reselection indication is allowed to be allowed (e.g. 0 or 1), the terminal is allowed to perform cell reselection again on the same frequency;

if the intrafreqReselection indicates notAllowed (e.g. 1 or 0), it means that the terminal is not allowed to reselect the cell on the same frequency again;

3: in this example, the barred state of the cell and intrafreq reselection are combined to indicate the state of the DBTW, and similarly, the same method may be used in this scheme to indicate 1-bit information, for example: whether the base station supports a certain capability, or a certain special service.

As can be seen from the above, the scheme provided in the embodiment of the present application may implement that the existing fields in the existing MIB and/or PBCH indication are adopted, and the state of the DBTW is effectively indicated while the information overhead is not increased, so as to ensure that the UE can operate as expected.

It should be noted that, the solutions provided in the embodiments of the present application may further include the following solutions, that is, in addition to the two methods in the foregoing solutions indicating the DBTW state, the solutions may also indicate the DBTW state in association with other methods:

scheme 1: by associating with a cell ID (corresponding to the above cell identification information):

if (i.e. for example) the current cell ID is odd, it indicates that the state of DBTW is enable, otherwise it is disable. Specifically, the method comprises the following steps:

in NR, the cell ID is expressed as:

specifically, can

Wherein

And

is determined by PSS (Primary synchronization signal) and SSS (Secondary synchronization signal) sequence ID (corresponding to the above sequence information). Can be based on

At least one of the three values of (a) represents the state of the DBTW. Such as:

when the number is odd, the state of the DBTW is represented as enable, otherwise, the state is represented as disable; or vice versa;

when the number is odd, the state of the DBTW is enabled, otherwise, the state is disabled; or vice versa;

further: in addition to the cell ID parity determination, the cell IDs may be grouped, such as cell IDs 0 to 400 for group 1 and 401 to 1000 for group 2. The state of the cell adopting the DBTW of the group 1 is enable; the state in which the cells of group 2 adopt the DBTW is disabled or vice versa.

The solution 1 includes a third corresponding relationship between the cell identification information and the first information corresponding to the target corresponding relationship; the cell identification information comprises parity information and/or affiliated group information of cell identification; the cell identification comprises primary synchronization signal PSS sequence information, secondary synchronization signal SSS sequence information and at least one of cell identifications obtained according to the PSS sequence information and the SSS sequence information.

Scheme 2: presetting some fields in the MIB to determined values on the unlicensed spectrum, and indicating the state of the DBTW by using the fields;

such as: if SCS and SSB of the PDCCH are in one-to-one correspondence (if two numerical values are the same), SCS of the control channel is directly calculated from SCS of the SSB; indicating a PDCCH SCS parameter (carrier spacing common, control channel subcarrier parameter) for indicating a state of the DBTW; such as: when the Carrier SpacingCommon is 0, the DBTW state is indicated as enabled, otherwise, the DBTW state is disabled. Or vice versa;

for another example: assuming that the Position of the data DMRS is a fixed value in the MIB, the indication (such as DMRS-TypeA-Position) is used for indicating the state of the DBTW; such as: when the dmrs-TypeA-Position is 0, the DBTW state is indicated as enable, otherwise, the DBTW state is disable; or vice versa (i.e., 0 indicates that the DBTW state is disabled, otherwise it is enabled; the above reference to "vice versa" is analogous to this understanding).

The solution 1 includes a fourth corresponding relationship between the first field filled with a preset value in the master information block MIB on the unlicensed spectrum and the first information corresponding to the target corresponding relationship.
