Description

Information transmission method, device, terminal and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, an information transmission apparatus, a terminal, and a base station.

Background

The existing base station sends TAC (Timing Advance Command) to the terminal in two ways. In the random Access procedure, the base station determines a TA value by measuring a Preamble received, and sends the TA value to the terminal through a Timing Advance Command field of an RAR (random Access Response). In both cases, the base station updates the TA value using a closed-loop mechanism, and the base station determines the TA value for each terminal based on measuring the uplink transmission of the corresponding terminal. If a specific terminal needs to be corrected, the base station sends TAC to the terminal and requires the terminal to update the uplink transmission timing. The TAC is sent to the terminal through a Timing Advance Command MAC control element.

At present, uplink timing synchronization update actively sent by a terminal can only be carried out in a random access mode. Although the terminal can acquire the uplink timing synchronization information update again, the accuracy of the acquired timing synchronization information is low, and the use requirement of a scene with high timing synchronization requirement cannot be met.

Detailed Description

In the embodiment of the present invention, the term "and/or" describes an association relationship of an associated object, and indicates that three relationships may exist, for example, a and/or B, and may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

To facilitate an understanding of the method of the embodiments of the present application, a brief description of the prior art follows.

(1) Principle of uplink synchronization

An important feature of uplink transmission is that different terminals are orthogonally multiple-access in time and frequency. I.e. uplink transmissions from different terminals of the same cell do not interfere with each other. To ensure orthogonality of uplink transmissions and avoid intra-cell interference, the base station requires that signals from different terminals in the same subframe but in different frequency domain resources arrive at the base station substantially aligned in time. And the uplink transmission of different terminals in the same cell is ensured to be aligned in time through uplink synchronization.

In order to ensure time synchronization at the base station side, an Uplink Timing Advance (Uplink Timing Advance) mechanism is adopted in the current system. From the terminal perspective, the timing advance is essentially a negative offset (negative offset) between the start time of receiving the downlink subframe and the time of transmitting the uplink subframe. The base station can control the arrival time of uplink signals from different terminals at the base station by appropriately controlling the offset of each terminal. For a terminal far away from the base station, due to a larger transmission delay, the terminal near the base station is required to transmit uplink data in advance.

(2) Uplink timing synchronization maintenance mechanism

The base station obtains the uplink timing advance of each terminal by measuring the uplink signal, and sends the TAC to the terminals in a corresponding mode to maintain the uplink synchronous timing. In the current system, a Timing Advance Command is sent to a terminal in two ways, and the detailed process is described as follows:

the first method is as follows: initial uplink synchronization process: in the random access process, the base station determines a TA value by measuring the received preamble and sends the TA value to the terminal through a Timing Advance Command field of the RAR.

The second method comprises the following steps: and (3) uplink synchronous updating process: the base station updates the uplink timing advance by using a closed-loop mechanism. The base station determines a TA value for each terminal based on measuring uplink transmissions of the corresponding terminals.

If a specific terminal needs to be calibrated, the base station sends a Timing Advance Command to the terminal to request the terminal to update the uplink transmission Timing. The Timing Advance Command is transmitted to the terminal through the Timing Advance Command MAC control element.

For the uplink timing synchronization update initiated by the UE actively, the uplink timing synchronization update can only be implemented in a random access manner. Although the terminal can acquire the uplink timing synchronization information update again, the accuracy of the acquired timing synchronization information is low, and the use requirement cannot be continuously met under the scene that the timing synchronization requirement is more strict and introduced by Rel-17.

In order to solve the above problems, embodiments of the present application provide an information transmission method and apparatus, where the method and apparatus are based on the same application concept, and because the principles of the method and apparatus for solving the problems are similar, the apparatus and method may be implemented by referring to each other, and repeated details are not repeated.

As shown in fig. 1, a schematic flow chart of an information transmission method provided in an embodiment of the present invention is applied to a terminal, and includes:

step 101: a terminal generates an uplink signaling, wherein the uplink signaling comprises uplink timing synchronization updating indication information;

it should be noted that the uplink signaling is signaling other than signaling used by the terminal in the random access process.

Here, the uplink timing synchronization update indication information is used to instruct the base station to update the uplink timing synchronization information. In other words, the uplink timing synchronization update indication information is used to indicate that the terminal has a need for the base station to update the uplink timing synchronization information.

Step 102: the terminal sends an uplink signaling to the base station;

here, the terminal triggers the base station to perform an update operation of the uplink timing synchronization information based on the uplink signaling.

Step 103: and the terminal receives the updated uplink timing synchronization information sent by the base station.

In this step, the terminal receives the updated uplink timing synchronization information sent by the base station after the base station executes the update operation of the uplink timing synchronization information according to the received uplink signaling.

The information transmission method of the embodiment of the invention generates an uplink signaling through a terminal, wherein the uplink signaling comprises uplink timing synchronization updating indication information; sending an uplink signaling to a base station; and then, the terminal receives the updated uplink timing synchronization information sent by the base station, and thus, the terminal sends the generated uplink signaling to the base station to trigger the base station to perform uplink timing synchronization updating, so that the terminal can acquire timing synchronization information with higher precision more quickly, and the use requirement under the scene with higher timing synchronization requirement is met.

Optionally, the uplink signaling includes one of:

RRC dedicated signaling;

uplink MAC CE signaling;

and uplink physical layer signaling.

Here, the terminal may instruct the base station to perform an update operation of the uplink timing synchronization information through RRC (Radio Resource Control) dedicated signaling.

The terminal may also instruct the base station to perform an update operation of the uplink timing synchronization information through an uplink MAC CE (Media Access Control Element) signaling.

The terminal can also instruct the base station to execute the updating operation of the uplink timing synchronization information through uplink physical layer signaling.

Optionally, when the uplink signaling is RRC dedicated signaling, the uplink timing synchronization update indication information is first indication information or a first boolean variable value.

The RRC dedicated signaling includes an indication of a preset number of bits, where the indication is used to indicate whether the base station needs to perform an update operation of the uplink timing synchronization information.

It should be noted that the indication (uplink timing synchronization update indication information) included in the RRC dedicated signaling in the embodiment of the present invention is first indication information or a first boolean variable value, where the first indication information is used to instruct the base station to update the uplink timing synchronization information, or the first boolean variable value is used to instruct the base station to update the uplink timing synchronization information.

Alternatively, the preset number of bits is 1 bit. Specifically, whether the base station needs to perform the update operation of the uplink timing synchronization information can be indicated by "0" or "1", in other words, whether the terminal needs to update the uplink timing synchronization information by the base station can be indicated by "0" or "1". For example, the indication "0" (which may be the content of the first indication information) indicates that the base station is instructed to update the uplink timing synchronization information (which may also be understood as indicating that the terminal has a need for the base station to update the uplink timing synchronization information), and the indication "1" indicates that the base station does not need to update the uplink timing synchronization information (which may also be understood as indicating that the terminal has a need for the base station to update the uplink timing synchronization information).

It should be noted that a boolean variable is a variable having two logic states, and includes two values: true and false. For example, a boolean variable true indicates that the base station is instructed to update the uplink timing synchronization information (which may also be understood as indicating that the terminal has a need for the base station to update the uplink timing synchronization information), and a boolean variable false indicates that the base station does not need to update the uplink timing synchronization information (which may also be understood as indicating that the terminal has a need for the base station to update the uplink timing synchronization information).

In particular, true and false can be characterized by an assignment to a boolean variable, such as an assignment of "0" (which may be the first boolean variable value) characterizing true and an assignment of "1" characterizing false.

Here, when the RRC dedicated signaling is an existing dedicated signaling, the indication may be added to the existing dedicated signaling to instruct the base station to update the uplink timing synchronization information. Optionally, the RRC dedicated signaling is user assistance information. For example, an uplink timing update indication is added to the user Assistance Information (UE Assistance Information IE) to instruct the base station to update the uplink timing synchronization Information. The method comprises the following specific steps:

in the case that the RRC dedicated signaling is a newly defined RRC dedicated signaling, specifically, an uplink timing synchronization update dedicated signaling uplink timing update IE may be defined, where the IE includes a boolean variable to indicate whether the base station needs to update the uplink timing synchronization information. In the embodiment of the present invention, the IE includes a first boolean variable value, which is used to instruct the base station to update the uplink timing synchronization information, that is, instruct the base station to perform an update operation of the uplink timing synchronization information. The method comprises the following specific steps:

optionally, when the uplink signaling is an uplink MAC CE signaling, the uplink timing synchronization update indication information is a logical channel identifier LCID value reserved in the uplink MAC CE signaling.

It should be noted that, a value for the UL-SCH LCID of the uplink synchronization channel may be newly defined through the LCID value reserved in the uplink MAC CE signaling, so as to indicate whether the base station needs to perform an update operation of the uplink timing synchronization information.

Optionally, the base station is instructed to update the uplink timing synchronization information through any value of the reserved LCID in the uplink MAC CE signaling.

In other words, any value in the LCID reserved in the uplink MAC CE signaling indicates that the terminal has a need for the base station to update the uplink timing synchronization information.

Specifically, the base station may be instructed to update the uplink timing synchronization information by using any value of LCID reserved in the uplink MAC CE signaling from 33 to 51.

It should be noted that the base station only needs to receive the LCID used for instructing the base station to update the uplink timing synchronization information in the uplink MAC CE signaling, which indicates that the base station needs to perform the operation of updating the uplink timing synchronization information. Which may be a fixed size of 0 bit corresponding to a load, such as indicating in what manner (e.g., period, consecutive times, etc.) the base station transmits the uplink timing synchronization information.

Optionally, when the uplink signaling is uplink physical layer signaling, the uplink timing synchronization update indication information is second indication information.

And the second indication information is used for indicating the base station to update the uplink timing synchronization information. In other words, the second indication information indicates that the terminal has a need for the base station to update the uplink timing synchronization information.

Here, the uplink physical layer signaling includes an indication of a preset number of bits, where the indication is used to indicate whether the base station needs to perform an update operation of the uplink timing synchronization information.

It should be noted that, in the embodiment of the present invention, the indication included in the uplink physical layer signaling is second indication information, which indicates the base station to update the uplink timing synchronization information.

Optionally, the preset number of bits is 1 bit. Specifically, whether the base station needs to perform the update operation of the uplink timing synchronization information can be indicated by "0" or "1". For example, the indication "0" (which may be the content of the second indication information) indicates that the base station is instructed to update the uplink timing synchronization information, and the indication "1" indicates that the base station does not need to update the uplink timing synchronization information.

Optionally, the uplink physical layer signaling is an existing dedicated signaling or a newly defined uplink dedicated physical layer signaling.

When the uplink physical layer signaling is the existing dedicated signaling, the uplink physical layer signaling may be a Scheduling Request (SR), where the SR is used to Request a resource and also used to instruct the base station to update the uplink timing synchronization information. I.e. indicates that each UE is configured with an independent SR configuration.

In the case that the uplink physical layer signaling is newly defined uplink dedicated physical layer signaling, the uplink dedicated physical layer signaling may be to add an uplink timing synchronization update dedicated transmission signal in the physical layer.

Optionally, the uplink signaling further includes sending configuration indication information, configured to instruct the base station to send the updated uplink timing synchronization information according to a preset configuration, where the preset configuration is determined by the terminal.

It should be noted that the preset configuration may be understood as a load corresponding to the uplink signaling, which may be customized according to different requirements, where the preset configuration is determined by the terminal, and includes but is not limited to a period (i.e., each transmission interval) when instructing the base station to transmit the updated uplink timing synchronization information, a consecutive number (i.e., a consecutive number of transmissions), and the like.

As shown in fig. 2, a schematic flow chart of an information transmission method provided in an embodiment of the present invention is applied to a base station, and includes:

step 201: a base station receives an uplink signaling sent by a terminal, wherein the uplink signaling comprises uplink timing synchronization updating indication information;

Step 202: the base station updates the uplink timing synchronization information according to the uplink signaling to obtain updated uplink timing synchronization information;

in this step, the base station updates the uplink timing synchronization information according to the received uplink signaling, that is, performs an update operation of the uplink timing synchronization information to obtain updated uplink timing synchronization information.

Step 203: and the base station sends the updated uplink timing synchronization information to the terminal.

In this step, the base station sends the obtained updated uplink timing synchronization information to the terminal, so that the terminal can acquire timing synchronization information with higher precision more quickly, and the use requirement under the scene with higher timing synchronization requirement is met.

The information transmission method of the embodiment of the invention receives an uplink signaling sent by a terminal through a base station, wherein the uplink signaling comprises uplink timing synchronization updating indication information; then, the base station updates the uplink timing synchronization information according to the uplink signaling to obtain the updated uplink timing synchronization information; and sending the updated uplink timing synchronization information to the terminal, so that the terminal can acquire the timing synchronization information with higher precision more quickly, and the use requirement under the scene with higher timing synchronization requirement is met.

Optionally, the uplink signaling includes one of:

RRC dedicated signaling;

uplink MAC CE signaling;

and uplink physical layer signaling.

As an optional implementation manner, the uplink signaling further includes sending configuration indication information, configured to instruct a base station to send updated uplink timing synchronization information according to a preset configuration, where the preset configuration is determined by the terminal; in step 203 of the embodiment of the present invention, the sending, by the base station, the updated uplink timing synchronization information to the terminal includes:

The preset configuration includes a period, a continuous number of times, and the like when the base station is instructed to send the updated uplink timing synchronization information, and the preset configuration may be customized according to different requirements, which is not specifically limited herein.

The following three embodiments specifically describe the implementation process of the method according to the embodiment of the present invention from the perspective of the interaction between the devices.

Embodiment one terminal instructs the base station to update the uplink timing synchronization information through RRC dedicated signaling, see fig. 3

Step 1: the terminal sends RRC dedicated signaling to the base station;

here, the terminal triggers the base station to perform an update operation of the uplink timing synchronization information by transmitting RRC dedicated signaling to the base station.

The RRC dedicated signaling may be 1-bit first indication information, where the first indication information indicates the base station to update the uplink timing synchronization information, and it can also be understood that the first indication information indicates that the terminal has a need for the base station to update the uplink timing synchronization information.

It should be noted that the RRC dedicated signaling may be extended based on the existing dedicated signaling, for example, adding an indication to the existing user assistance information to indicate whether the base station needs to perform the uplink timing synchronization information updating.

The RRC dedicated signaling may also be newly defined RRC dedicated signaling.

And 2, step: and the base station sends the updated uplink timing synchronization information to the terminal.

The base station performs an update operation of the uplink timing synchronization information according to the received RRC dedicated signaling, and transmits the updated (latest) uplink timing synchronization information to the terminal.

In the second embodiment, the terminal instructs the base station to update the uplink timing synchronization information through uplink MAC CE signaling, see fig. 4

Step 11: the terminal sends an uplink MAC CE signaling to the base station;

here, the terminal triggers the base station to perform an update operation of the uplink timing synchronization information by sending uplink MAC CE signaling to the base station.

The content of the uplink MAC CE signaling may be a newly defined value for UL-SCH LCID, indicating whether the base station needs to update the uplink timing synchronization information. In this embodiment, the value of the UL-SCH LCID is used to instruct the base station to update the uplink timing synchronization information.

Here, the base station may be instructed to update the uplink timing synchronization information by a value of any one of the LCIDs reserved in the uplink MAC CE signaling, and it may also be understood that a value of any one of the LCIDs reserved in the uplink MAC CE signaling indicates that the terminal has a need for the base station to update the uplink timing synchronization information.

Step 12: and the base station sends the updated uplink timing synchronization information to the terminal.

It should be noted that, the base station performs an update operation of the uplink timing synchronization information according to the received uplink MAC CE signaling, and sends the updated (latest) uplink timing synchronization information to the terminal.

In the third embodiment, the terminal instructs the base station to update the uplink timing synchronization information through uplink physical layer signaling, see fig. 5

Step 111: a terminal sends an uplink physical layer signaling to a base station;

here, the terminal sends uplink physical layer signaling to the base station to trigger the base station to perform an update operation of the uplink timing synchronization information.

The uplink physical layer signaling may be 1-bit second indication information that indicates the base station to update the uplink timing synchronization information, or may be understood as that the second indication information indicates that the terminal has a need for the base station to update the uplink timing synchronization information.

It should be noted that the uplink physical layer signaling may be an existing dedicated signaling, for example, when the UE is configured to perform an SR request, the UE further requests timing synchronization update, that is, each UE is configured with an independent SR configuration to perform indication.

The uplink physical layer signaling may also be newly defined uplink dedicated physical layer signaling, for example, adding uplink timing synchronization update dedicated transmission signal in the physical layer.

Step 112: and the base station sends the updated uplink timing synchronization information to the terminal.

It should be noted that, the base station performs an update operation of the uplink timing synchronization information according to the received uplink physical layer signaling, and sends the updated (latest) uplink timing synchronization information to the terminal.

It should be noted that, in the information transmission method according to the embodiment of the present invention, the condition that the terminal triggers sending the uplink signaling is implemented by the terminal, that is, the method belongs to the algorithm category implemented by the terminal itself.
