In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be referred to as a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile phone (or called a "cellular" phone) and a computer having a mobile terminal device, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN), and may exchange languages and/or data with the RAN.

The embodiment of the application provides an information indication method, a terminal and a storage medium, which are used for solving the technical problem that the utilization rate of bit resources in PBCH (physical broadcast channel) is low in the prior art.

The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

In the 5G system, the demand of users on the bandwidth and throughput of the wireless network is increasing. In order to better utilize unlicensed spectrum resources, provide higher service rate and better user experience for users, an unlicensed (un-licensed) spectrum is introduced in a 5G system. Compared with the exclusive characteristic of the authorized spectrum, the unlicensed spectrum has a shared characteristic, that is, as long as an access point conforming to a certain regulation is satisfied, the spectrum can be used for receiving and transmitting data, in order to enable each access node to better coexist, after the 5G system introduces the unlicensed spectrum, a Listen Before Talk (LBT) channel access mechanism is adopted, that is, any transmitting node needs to monitor (energy detection) a channel to be transmitted before transmitting data, and can transmit data only when the channel is in an IDLE (IDLE) state, otherwise, the monitoring needs to be continued. Wherein, the sending node (including the network device or the terminal device) listens to the channel idle before wanting to occupy the resource is called as LBT listening success, otherwise called as LBT listening failure (or LBT failure).

In the unlicensed spectrum, it is sometimes necessary to perform LBT base station, but SSBs (synchronization blocks) transmitted by the base station are periodic, and the terminal expects to receive 1 or more SSBs transmitted by the base station at a certain period (high frequency supports transmitting 64 different SSBs at most).

The DBTW function assigns more than 1 candidate SSB transmission location to each SSB (e.g., two candidate locations per SSB), and the base station attempts to transmit the corresponding SSB at the second candidate location after LBT fails at the first candidate location, thus increasing the probability of SSB transmission.

In order for the UE to effectively receive data transmitted by the base station or transmit uplink signal/channel data, two states, i.e., LBT-ON or NO-LBT (i.e., LBT-OFF), need to be indicated, which requires a maximum of 1-bit data indication.

In addition, when the transmitting SSB supports the DBTW function, the candidate location index of the SSB exceeds 64, for example, 128, at this time, 7 bits are needed to indicate the candidate location index of the SSB, that is, an additional 1-bit SSB candidate location indication information (index 7-bit information) needs to be added on the basis of the original indicated candidate location (the candidate location index is within 64, and 6-bit indication is needed).

Currently, SSB is composed of three parts, primary Synchronization Signals (PSS), secondary Synchronization Signals (SSS), and PBCH. The PBCH content includes 23-bit MIB and 8-bit PBCH payload (additional PBCH payload), and the remaining 1bit is reserved bit and is not used generally.

The DBTW function indication, the LBT status indication, and the additional 1-bit SSB candidate position indication that need to be added usually need to occupy at least 3 bits of data, so that at present, the three newly added first indication information cannot be indicated even if the reserved bits in the PBCH are used, if the number of bits in the PBCH is increased, the data amount of the PBCH will be increased, and the transmission efficiency of the PBCH will be reduced.

The inventor discovers through research on the three first indication information that:

on unlicensed spectrum, the DBTW function is not always performed, and in certain cases, the DBTW technology may not be used, but may be directly transmitted, for example: when local regulations stipulate: the base station does not perform LBT before transmitting data on the unlicensed spectrum, or the base station employs the rule of "control short message", or the base station may directly transmit the SSB without performing LBT. For the UE to receive the SSB efficiently, it is only necessary to instruct the DBTW function enable/disable two states, which requires 1-bit data at most.

And for unlicensed spectrum, according to prior art standards, it is not required that LBT be performed, i.e. some cases require LBT to be performed, and some cases do not require LBT to be performed. Such as: some countries/regions may mandate LBT, some countries/regions may not mandate LBT, and for non-mandated regions/countries, the base station may determine, for example: and when the current peripheral interference is serious, performing LBT, otherwise, not performing LBT.

However, the above-mentioned index 7 th bit information is only needed when the SSB supports the DBTW function, so the inventors think that the association relationship among the three can be used to jointly indicate the above-mentioned 3 pieces of first indication information with less binary data, for example, 2 pieces of binary data are jointly indicated for the above-mentioned three pieces of first indication information, and the indicated basic scheme is shown in table 1.

TABLE 1

In table 1, b0 and b1 each represent a binary data bit, and a binary data bit corresponds to a binary data, and the value of the binary data may be 0 or 1. b0 and b1 have no front and back position relation between the 2 binary data bits.

It should be noted that the DBTW function is a method for the base station to transmit/receive the SSB, and when the DBTW function is enabled and disabled, the base station uses different transmission methods, and the corresponding terminal uses different reception methods. In the embodiment provided by the present invention, the enabling and disabling of the DBTW function is only one expression, and in practical applications, the DBTW function may be expressed by other names (for example, the DBTW function is enabled or disabled), which is not limited herein.

Similarly, if a plurality of other first indication information having association relationship needs to be added in a new protocol or a new technical standard, the association relationship between the plurality of first indication information may be utilized, and a small number of binary data may be used to jointly indicate the plurality of first indication information.

Referring to fig. 1, an embodiment of the invention provides a method for indicating information, and the processing procedure of the method is as follows.

Step 101: the terminal receives data through a physical broadcast channel PBCH;

step 102: reading a plurality of first indication information with association relation from the data, wherein the number of the plurality of first indication information is less than the number of binary data used for indicating the plurality of first indication information.

The first indication information in step 102 may be any one of a DBTW function indication, an LBT status indication, and an extra 1-bit SSB candidate location indication information, and may also be other additional indication information as the technology advances.

For example, the plurality of first indication information is DBTW function indication, LBT status indication, and an extra 1-bit SSB candidate location, where the existing PBCH has 32 bits, and only 1bit (reserved bit) is left unused, and it is assumed that in order to enable the PBCH to indicate more information, the number of bits of the PBCH is increased to 40 bits in the new technical standard, and it can be known from table 1 to indicate the three first indication information, and at most 2 bits in the PBCH in the new technical standard need to be occupied, so that the PBCH can leave more bits for other indication information, thereby improving the utilization rate of the PBCH.

For another example, the plurality of first indication information is LBT status indication, additional 1-bit SSB candidate positions, the existing PBCH has 32 bits, of which only 1bit (reserved bit) is left unused, and the remaining unused 1bit in the PBCH can be used to indicate the two first indication information.

In order to further reduce the requirement of the plurality of first indication information on the bits in the PBCH, the inventor further improves the indication manner of the value of binary data required by the plurality of first indication information, which is as follows:

the indication mode of any binary data value corresponding to the plurality of first indication information comprises the following modes:

the first method comprises the following steps: unused bits in the data received through PBCH indicate. For example, the existing PBCH has 32 bits, of which only 1bit (reserved bit) is left unused, the bit corresponding to the reserved bit in the data received by the PBCH is the unused bit in the data received by the PBCH, and the unused bit in the data received by the PBCH can be used to indicate any binary data corresponding to the plurality of first indication information.

And the second method comprises the following steps: and using the second indication information to reduce the data range and then indicating the surplus bits.

For example, there are 8 bits of PDCCH-ConfigSIB1 in the MIB, and the second indication information indicates that the terminal reads the control channel configuration information of the system message SIB1, where 4 bits indicate frequency domain information and the other 4 bits indicate time domain information.

2 can be represented by 4 bits ⁴ And =16 frequency domain information or time domain information, and if the representation range of the time domain information and/or the frequency domain information is reduced to represent 8 frequency domain information, the frequency domain information only needs to occupy 3 bits, so that 1bit can be saved, and binary data is indicated by the 1bit of the balance. If the time domain information is also reduced to represent 8 kinds, the corresponding 1bit which can be more than balance indicates another binary data. The range of the second indication information can be reduced according to the factIt is not limited herein as the case may be. If the plurality of first indication information needs exactly 2 binary data for indication, the two binary data indications of the balance can be used.

In the embodiment provided by the invention, the spare bits after the data range is reduced by the second indication information are used for indicating the binary data of the plurality of first indication information, so that the bit resource utilization rate of the PBCH can be improved.

And the third is that: a second indication information indication in the data received through the PBCH; wherein the second indication information includes indication information that specific bits have been occupied in the data received through the PBCH.

When any one of the binary data is indicated by the second indication information, the specified data in the second indication information has a data mapping relationship with the corresponding binary data. And the base station/terminal re-interprets or interprets the specific bit according to the data mapping relation. The data mapping relationship comprises a mapping relationship between the value of the designated data and the value of the binary data.

In this case, the specifying data may include:

the second indication information corresponds to a value of a state combination of the plurality of bits;

or, in the unlicensed spectrum, a specific value in the primary system information block MIB or an SCS parameter of a Physical Downlink Control Channel (PDCCH).

For example, the designated data is the value of the state combination of the plurality of bits corresponding to the second indication information, see table 2. The second indication information corresponds to 2 bits, and there are 4 combination modes (marked as state 1 to state 4) corresponding to the 2 bits, where the binary data mapped in the state 1 to state 3 takes a value of 1, and the binary data mapped in the state 4 takes a value of 0.

TABLE 2

If the upper binary data indicates the DBTW function instruction, the terminal may determine that the value of the DBTW function instruction is 1 according to the mapping relationship when the terminal reads the value corresponding to 2 bits in the second instruction information as 01, and may determine that the value of the DBTW function instruction is 0 according to the mapping relationship when the terminal reads the value corresponding to 2 bits in the second instruction information as 11.

Of course, the 2 bits in table 1 may also be a part of a plurality of bits corresponding to the second indication information, for example, the second indication information is calculated to belong to the same quasi co-address relationship SSB, and the calculation in table 1 belongs to the same quasi co-address relationship SSB (denoted as Q).

It should be understood that the correspondence relationship between the status combination and the DBTW function indication is not limited to the relationship in table 1, and may be other mapping relationships set by a user, and the bit corresponding to the second indication information is not limited to 2 bits, and may be 3 bits or more, and may be freely set by the user.

For another example, in the unlicensed spectrum, the second indication information may be an MIB, the specified data may be values of some fields in the MIB (e.g., DMRS-type a-Position indicated in the MIB that the DMRS Position of the data is a specific value, such as DMRS-type a-Position), when the value of mrs-type a-Position is 0, the data is mapped to a value of binary data of 0, and when the value of mrs-type a-Position is not 0, the data is mapped to another value of binary data of 1. If the first indication information indicated by the binary data corresponding to the mapping relationship is the DBTW function indication, when the terminal reads mrs-TypeA-Position with the value of 0, determining that the value of the DBTW function indication is 0 according to the mapping relationship, and indicating that the DBTW function indication is disabled; or when the value of the terminal reading mrs-typeA-Position is not 0, determining that the value of the DBTW function instruction is 1 according to the mapping relation, and indicating that the DBTW function instruction is enabled.

As another example, in the unlicensed spectrum, the designated data is SCS parameters of PDCCH. (carrierspacincommon) maps the value 0 of the SCS parameter to the value 0 of the binary data, and maps the value 1 of the SCS parameter to another value 1 of the binary data, or vice versa.

In the embodiment provided by the invention, the value of the binary data of the first indication information is indicated by the second indication information in the PBCH, when the binary data of at least one first indication information in the plurality of first indication information is indicated in this way, the number of the bits in the PBCH occupied by the plurality of first indication information can be further reduced, and if the binary data of the plurality of first indication information is indicated in this way, the bits in the PBCH can be not occupied, so that the bit resource in the PBCH is improved, the protocol complexity is reduced, and the influence on the existing protocol is reduced.

In a possible implementation manner, the data mapping relationship between the designated data in the second indication information and the corresponding binary data further includes a mapping relationship between a value grouping of the designated data and a value of the binary data.

For example, the state 1 to the state 3 in table 2 may be regarded as one value group, the state 4 may be regarded as another value group, the group corresponding to the state 1 to the state 3 is mapped to the value 1 of the binary data, and the group corresponding to the state 4 is mapped to the other value 0 of the binary data.

For another example, the cells governed by the base station are divided into two groups (denoted as group 1 and group 2), where group 1 includes cell serial numbers 0 to 400, group 2 includes cell serial numbers 401 to 1000, group 1 is mapped as value 1 of binary data, and group 2 is mapped as another value 0 of binary data. If the binary data indicates the DBTW function indication, when the cell serial number read by the terminal from the PBCH is 0, according to the mapping relationship, it may be determined that the value of the SBTW function indication is 1, indicating that the DBTW function indication is enabled; when the cell serial number read by the terminal from the PBCH is 500, according to the above mapping relationship, it may be determined that the value of the SBTW function indication is 0, indicating that the DBTW function indication is enabled.

The value packet may also be a parity packet of a value of the designated data, and the corresponding designated data may be any one of a current cell sequence number, a primary synchronization sequence number in the current cell sequence number, and a secondary synchronization sequence number in the current cell sequence number.

For example, when the current cell serial number is an odd number, the value of the mapping binary data is 1, and when the current cell serial number is an even number, the other value of the mapping binary data is 0. If the binary data indicates the LBT status indication, when the cell serial number read by the terminal from the PBCH is an odd number, the value of the LBT status indication can be determined to be 1 according to the mapping relation, and the LBT-ON is represented; when the sequence number of the cell read by the terminal from the PBCH is odd, the value of the LBT status indication can be determined to be 0 according to the mapping relation, which represents LBT-OFF.

Or, when the primary synchronization sequence number in the current cell sequence number is an odd number, the mapped binary data takes a value of 1, and when the primary synchronization sequence number in the current cell sequence number is an even number, the mapped binary data takes another value of 0.

Or, when the secondary synchronization sequence number in the current cell sequence number is an odd number, the mapped binary data takes a value of 1, and when the secondary synchronization sequence number in the current cell sequence number is an even number, the mapped binary data takes a value of 0.

In the embodiment provided by the present invention, the plurality of first indication information may further include an association relation DBTW function indication, a listen before talk LBT status indication, and an extra 1-bit SSB candidate location indication.

When the plurality of first indication information includes three indications, i.e., the DBTW function indication, the listen-before-talk LBT status indication, and the additional 1-bit SSB candidate location indication, it can be known from table 1 that they need to use 2 binary data indications, and in combination with the various schemes of the binary data indications provided in the foregoing embodiments, the 2 binary data may occupy bits in the PBCH, or may not occupy. When the 2 binary data occupy the bit in the PBCH, the bit is indicated by the unused bit in the PBCH or the remaining bit after the second indication information reduces the data range; when the 2 binary data do not occupy bits in the PBCH or occupy 1bit, the binary data of the unoccupied bits are indicated by the second indication information in the PBCH.

In one possible implementation, the DBTW function indication, the listen-before-talk LBT status indication, and the extra 1-bit SSB candidate position indication share two binary data, and the two binary data correspond to two binary data bits; wherein the DBTW function indicates that a single binary data bit is used and the LBT status indication is multiplexed with the extra 1-bit SSB candidate location indication by one binary data bit.

As shown in table 1, in jointly indicating the DBTW function indication, the LBT status indication, and the extra 1-bit SSB candidate location indication, a single binary data bit (b 0) is used to indicate the DBTW function indication, and the LBT status indication and the extra 1-bit SSB candidate location indication multiplex another binary data bit (b 1).

In one possible embodiment, multiplexing the DBTW function indication with the extra 1-bit SSB candidate location indication is performed by:

the binary data bit indicates one of an LBT status indication and an extra 1-bit SSB candidate location indication, and one of the unused binary data bits uses a default value.

Continuing with table 1, when data bit b1 indicates an LBT status indication, the additional 1-bit SSB candidate location indication uses a default value of 0; the LBT status indication uses the default value LBT-ON when the data bit b1 indicates an additional 1-bit SSB candidate position indication.

One possible implementation, in which the data bit indicates one of the LBT status indication and the additional 1-bit SSB candidate position indication, and the one of the unused data bits uses a default value, may be implemented as follows:

when the DBTW function is enabled, the additional 1-bit SSB candidate position indicates that binary data bits are used, and the default value of the LBT status indication is LBT-ON.

By the above indication method, when the base station indicates that the DBTW function is DBTW enabled, which means that the base station needs to perform LBT when transmitting SSB, the base station also needs to perform LBT when transmitting other data channels, so that when the DBTW is enabled, the LBT status is always LBT-ON, and the range of SSB candidate position index values needs to be expanded, that is, b1 (multiplexed data bit) needs to be used to indicate the SSB candidate position.

When the DBTW function is disabled, the LBT status indicates that binary data bits are used and the default value of the additional 1-bit SSB candidate location indication is 0.

With the above indication, when the base station indicates that the DBTW function indicates DBTW is disabled, the base station only transmits SSBs at no more than 64 existing candidate positions, so b1 (multiplexed data bits) is not needed to expand the SSB candidate position index, i.e., the additional 1-bit SSB candidate position indication may use the default value of 0, or only use the existing number of bits to calculate the SSB candidate position index; however, in this case, the LBT status indication may be LBT-ON or LBT-OFF, and b1 (multiplexed data bit) is used for indication.

It should be noted that, as soon as possible, in the embodiment provided by the present invention, only the joint indication of the DBTW function indication, the LBT status indication, and the extra 1-bit SSB candidate position indication is shown, but a person skilled in the art may also jointly indicate a plurality of other first indication information having an association relationship in a similar manner based on the above-mentioned scheme, and therefore, the scheme in this embodiment may not be limited to the joint indication of the above-mentioned 3 kinds of first indication information.
