System information transmission processing method and user terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for processing system information transmission and a user terminal.

Background

In future communication systems (e.g., 5G communication systems), the system information may be divided into two types, one is periodically broadcast-transmitted system information, and the other is request-based (on-demand) transmitted system information. The system information sent based on the request means that the user terminal sends a system information request to the base station, and the base station sends the system information corresponding to the request to the user terminal. However, the procedures based on the system information requested to be transmitted involve Radio Resource Control (RRC) layer and Medium Access Control (MAC) layer procedures, and no complete solution is provided. It can be seen that, at present, the performance of the system information processing based on request sending by the user terminal is poor.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a structural diagram of a processing system for system information transmission according to an embodiment of the present invention, and as shown in fig. 1, the processing system includes a user terminal 11 and a base station 12, where the user terminal 11 may be a ue (user equipment), such as a terminal-side Device, for example, a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a laptop Computer (L ap Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that a specific type of the user terminal 11 is not limited in the embodiment of the present invention, and the base station 12 may be a 5G base station (e.g., a gNB, a 5 NRNB), or may be a 4G base station (e.g., an eNB), or may be a 3G base station (e.g., an NB), and it should be noted that a specific type of the base station 12 is not limited in the embodiment of the present invention.

It should be noted that the specific functions of the user terminal 11 and the base station 12 are described in detail through a plurality of embodiments below.

Referring to fig. 2, fig. 2 is a schematic diagram of a processing method for system information transmission according to an embodiment of the present invention, and as shown in fig. 2, the processing method includes the following steps:

step 201, the RRC layer of the ue triggers the MAC layer of the ue to send a system information request to the base station, and starts a timer.

The above-mentioned RRC layer triggering the MAC layer of the user terminal to send the system information request to the base station may be that the RRC layer sends a message content corresponding to the system information request to the MAC layer to trigger the MAC layer to send the system information request to the base station. In addition, the system information request can be Msg1 or Msg3 in the random access process, so that the system information request can be sent to the base station through Msg1 or Msg3, and the transmission overhead can be reduced.

For example: the user terminal can determine the Preamble (Msg1) to be sent and the corresponding time-frequency resource position according to the required system information message (SI message) and the configuration information of the Preamble (Preamble) associated with the SI message broadcasted by the network; the network side equipment determines the SI message requested by the user terminal according to the received Preamble and the position of the corresponding time-frequency resource, and feeds back the Msg 2; the user terminal receives the Msg2, and the user terminal can confirm that the request message has been successfully received by the network side device. Wherein, the SI message may include one or more System Information Blocks (SIBs)

Or, the user terminal determines that the required SI message is sent by using an on demand mode, but the network does not broadcast the configuration information of the Preamble associated with the SI message; thus, the user terminal can select an available Preamble and a corresponding Random Access Channel (RACH) to send Msg 1; the network side equipment receives the Msg1, and allocates uplink wireless resources for the user terminal through the Msg2 for sending the Msg 3; the user terminal indicates the identifier of the requested SI message to the network side equipment in the Msg3 (for example: RRC message); the network side device confirms to the user terminal that Msg3 has been received in Msg 4.

The duration of the timer may be notified to the ue by the base station through a broadcast or a dedicated RRC message, or may be determined by Minimum System Information (Minimum System Information MSI) notification or protocol predefined, and the like, which is not limited in this embodiment of the present invention.

In addition, the ue may request one or more SI messages through a system information request procedure, that is, the system information request may request one or more SI messages.

Step 202, before the timer is overtime, if the RRC layer receives the system information sent by the base station, the timer is stopped.

The ue may start to monitor the system information sent by the base station after starting the timer, and the RRC layer receives the system information sent by the base station before the timer expires, so as to stop the timer. In addition, the system information received by the RRC layer may include:

the system information requests all or part of the requested system information.

And the system information here may be SI message, such as: the SI message received in step 202 may include all the SI messages requested by the ue or at least one requested SI message.

The above steps can be implemented by starting a timer based on the system information requested to be sent, and before the timer expires, stopping the timer if the RRC layer receives the system information sent by the base station, so that after receiving the system information, the RRC layer can stop processing the system information sent based on the request, thereby improving the performance of the user terminal in processing the system information sent based on the request.

It should be noted that, in the embodiment of the present invention, the method may be applied to a 5G communication system or other communication systems, for example: 6G communication system, etc., and the embodiments of the present invention are not limited thereto.

Referring to fig. 3, fig. 3 is a schematic diagram of a processing method for system information transmission according to an embodiment of the present invention, as shown in fig. 3, including the following steps:

step 301, the RRC layer of the ue triggers the MAC layer of the ue to send a system information request to the base station, and starts a timer.

As an optional implementation manner, the triggering, by the RRC layer of the user terminal, the MAC layer of the user terminal to send a system information request to the base station includes:

the RRC layer of the user terminal transmits the configuration information of Preamble to the MAC layer of the user terminal; or

The RRC layer of the user terminal transfers an RRC system information request message to the MAC layer of the user terminal.

After receiving the configuration information of the Preamble or the RRC system information request message, the MAC layer may send a system information request to the base station. The configuration information of the Preamble may be identification information of the Preamble code and/or time-frequency resource location information sent by the Preamble code, and the RRC system information request message may be a message content for requesting a system information request, for example: identification of the SI message requested by the user terminal.

In this embodiment, the system information request triggered by the configuration information of the Preamble may be sent in Msg1 in the random access procedure, and the system information request triggered by the RRC system information request message may be sent in Msg3 in the random access procedure.

In the embodiment, the MAC can be triggered to send the system information request to the base station in different modes, so that the flexibility of the user terminal can be improved, and different communication scenes can be applied.

Step 302, before the timer is overtime, if the RRC layer receives the system information sent by the base station, the timer is stopped.

As another optional implementation, the system information received by the RRC layer includes:

The system information received by the RRC layer may be system information broadcast and sent by the base station in response to the ue, or system information broadcast and sent by the base station in response to other ues, for example: the user terminal system information request fails to be sent, but other user terminals request the same system information and request to be sent successfully, so that the user terminal can also receive the system information.

Optionally, in this embodiment, before the timer expires, if the RRC layer receives the system information sent by the base station, the stopping the timer includes:

and before the timer is overtime, if the RRC layer receives the system information sent by the base station, the system information is considered to be successfully acquired, and the timer is stopped.

The step can realize that the system information can be considered to be successfully acquired as long as the user terminal receives all or part of the system information requested by the user terminal returned by the base station.

Step 303, if the timer is overtime, the RRC layer considers that the system information acquisition is failed.

Through step 303, when the real-time timer times out, it can be considered that the system information acquisition fails, so that the user terminal can perform corresponding processing, for example: the MAC layer stops the system information application process or the random access process, so that the performance of the user terminal for processing the system information sent based on the request is further improved.

It should be noted that, in this embodiment, step 303 is optional, for example: before the timer is overtime, the RRC layer receives the system information, so that the condition that the timer is overtime can not exist.

As another optional implementation, the RRC layer of the user terminal triggers the MAC layer of the user terminal to send a system information request to the base station, and after the step of the RRC layer starting the timer, the method further includes:

before the timer is overtime, the RRC layer receives the system information sent by the base station, and then the RRC layer informs the MAC layer to stop the random access process.

Wherein, after the RRC layer informs the MAC layer to stop the random access process, the MAC layer stops the random access process. In addition, the above-mentioned notifying the MAC layer to stop the random access procedure may be notifying the MAC layer to stop the random access procedure when the random access procedure initiated by the MAC layer is successful, or notifying the MAC layer to stop the random access procedure when the random access procedure initiated by the MAC layer fails.

For example: before the timer expires, if the RRC layer receives the system information sent by the base station, the RRC layer notifies the MAC layer to stop the random access procedure, which may include:

before the timer is overtime, the RRC layer receives the system information sent by the base station, and receives the random access process success message fed back by the MAC layer, so that the RRC layer informs the MAC layer to stop the random access process.

The process can refer to the example shown in fig. 4: as shown in fig. 4, the method comprises the following steps:

step 401, the RRC layer of the ue initiates a system request procedure, and starts a timer T, where the length of the timer T may be MSI notification or protocol specification or other manners.

The step may be a scheme of requesting system information by using Msg1, in which the RRC layer may transfer configuration information of Preamble to the MAC layer; or the step may be a scheme of requesting system information by Msg3, in which the RRC layer may generate an RRC SI request message and deliver it to the MAC layer;

step 402, the MAC layer of the ue initiates a random access procedure (RACH procedure) according to the RRC layer trigger, and the RACH procedure fails for the first time (dashed box).

For example: if the scheme of requesting system information by using the Msg1 is adopted, the failure can mean that the Msg2 is not received; if the scheme of requesting system information using Msg3 is adopted, failure may mean that Msg2 or Msg4 is not received.

In step 403, the MAC layer of the user terminal re-initiates the RACH procedure, and the procedure is successful (i.e., the random access procedure is successful).

If the scheme of requesting system information by Msg1 is adopted, the success of the RACH procedure may mean that the MAC layer successfully receives Msg2 in a random access procedure and confirms that Msg2 is a response to Msg 1;

if the scheme of requesting system information by Msg3 is adopted, the success of the RACH procedure may mean that the MAC layer successfully receives Msg4 in a random access procedure and confirms that Msg4 is a response to Msg 3.

In step 403a, the MAC layer of the ue feeds back a random access procedure success message to the RRC layer.

This step is optional.

Step 404, the RRC layer of the network side device receives the list of SI messages requested by the UE;

in this step, since the SI message list may be notified to the network-side device through Msg1 or Msg3, step 404 may be started before or after step 403 is ended;

step 405, after receiving the requested SI message, the RRC layer of the ue stops the timer T.

Here, the SI message may include all SI messages requested by the ue or at least one SI message requested by the ue.

Step 406, the user terminal RRC layer informs the MAC layer to stop the RACH procedure.

Wherein, the ue may monitor the requested SI message from step 401; it is also possible to start listening for the requested SI message after the success of step 403.

In addition, in the RACH procedure of step 403, for a scheme that uses Msg1 to request system information, the MAC layer obtains the SI message list requested by the user terminal through Msg 1; for the Msg3based scheme, the MAC layer obtains the SI message list requested by the user terminal through Msg 3; after obtaining the list, the MAC layer of the network side device may initiate step 404 without waiting until Msg2 or Msg4 is sent to the user terminal.

In addition, in order to reduce power consumption of the user terminal, the RRC layer of the user terminal triggers the MAC layer of the user terminal to send a system information request to the base station, and after the step of the RRC layer starting the timer, the method may further include:

the RRC layer receives a random access process success message fed back by the MAC layer;

if the random access process success message is received before the RRC layer receives the system information sent by the base station, the RRC layer does not need to notify the MAC layer to stop the random access process after receiving the system information sent by the base station; or

If the random access procedure success message is received before the timer is overtime and the RRC layer does not receive the system information sent by the base station, the MAC layer does not need to be informed to stop the random access procedure after the timer is overtime.

For example: in the example shown in fig. 4, after the RACH is successful (random access procedure is successful), the user terminal MAC layer may inform the RRC layer; after receiving the RACH success message of 403a, the RRC layer of the user terminal knows that the MAC layer has stopped the RACH procedure; thus, the RRC layer may not notify the MAC to stop the RACH after receiving the requested SI message (step 405) (i.e., step 406 is skipped). Similarly, if the random access procedure success message is received before the timer expires, the MAC layer does not need to be notified to stop the random access procedure after the timer expires, because if the timer expires, it indicates that the system information acquisition fails, and at this time, the MAC layer has stopped the RACH procedure.

In the above embodiment, in which the RRC layer receives the system information sent by the base station before the timer expires, and the RRC layer notifies the MAC layer to stop the random access process, it can also be implemented that the RRC layer notifies the MAC layer to stop the random access process when the random access process fails, so as to prevent the MAC layer from trying the random access process all the time after the RRC receives the system information, thereby reducing the power consumption of the user equipment.

As another optional implementation manner, if the timer expires, the determining, by the RRC layer, that the system information acquisition is failed includes:

and if the timer is overtime, the RRC layer considers that the system information acquisition is failed and informs the MAC layer to stop the random access process.

In this embodiment, if the timer is overtime, it may be determined that the system information acquisition is failed, and the MAC layer is notified to stop the random access process, so as to reduce power consumption of the ue.

In addition, in this embodiment, when the timer expires and the number of times of failure of the MAC layer random access procedure reaches a certain number of times, the MAC layer may be notified to stop the random access procedure. For example: before the step of the RRC layer informing the MAC layer to stop the random access procedure, the method further includes:

if the MAC layer fails to initiate the random access process for the Nth time, the MAC layer reports a random access process failure message to the RRC layer and continues to initiate the random access process, wherein N is an integer greater than or equal to 1.

Wherein N is that the base station notifies the ue through a broadcast or dedicated RRC message, and the MAC layer stops the random access procedure after receiving the RRC notification.

Through the steps, the MAC layer is informed to stop the random access process only when the timer is overtime and the failure times of the MAC layer random access process reach a certain number, so that the power of the user terminal is reduced, and the MAC layer is prevented from continuously initiating the random access process.

For example: as shown in fig. 5, the method comprises the following steps:

step 501, the RRC layer of the ue initiates a system request procedure, and starts a timer T, where the length of the timer T may be MSI notification or protocol specification or other manners.

step 502, the MAC layer of the user terminal initiates a random access RACH procedure according to the RRC layer trigger, and the RACH procedure fails for the first time (dashed box).

After the MAC layer of the ue performs N-1 attempts, the MAC layer fails to re-initiate the RACH procedure (N-th failure), step 503.

Step 503a, after the nth failure, the MAC layer of the ue reports an RACH procedure failure message to the RRC layer.

Here, N may be configured by RRC of the user terminal UE, and the configuration parameter of RRC may be from broadcast or dedicated configuration of the network.

In step 504, the MAC layer of the ue continues RACH attempt and fails.

That is, the RACH procedure of the MAC layer is not stopped by reaching the preset number.

Step 505, the timer T of the RRC layer of the user terminal is overtime, the system message request process fails, and the RRC layer notifies the MAC layer to stop the RACH process.

It should be noted that, in the above embodiment where the MAC layer reports a random access procedure failure message to the RRC layer and continues to initiate a random access procedure after the MAC layer has failed to initiate a random access procedure for the nth time, the same may be applied to the above-described embodiment where the RRC layer receives the system information sent by the base station before the timer times out, and the RRC layer notifies the MAC layer to stop a random access procedure, for example: as shown in fig. 6, the method comprises the following steps:

step 601, the RRC layer of the ue initiates a system request procedure, and starts a timer T, where the length of the timer T may be MSI notification or protocol specification or other manners.

step 602, the MAC layer of the ue initiates a random access RACH procedure according to the RRC layer trigger, where the RACH procedure fails for the first time (dashed box).

Step 603, after the MAC layer of the user terminal performs N-1 attempts, the MAC layer fails to re-initiate the RACH procedure (nth failure).

Step 603a, after the nth failure, the MAC layer of the ue reports an RACH procedure failure message to the RRC layer.

Step 604, the MAC layer of the user terminal continues the RACH attempt and succeeds.

Step 604a, the MAC layer of the user terminal feeds back a RACH success message to the RRC layer.

Step 605, the RRC layer of the network side device receives the list of SI messages requested by the UE;

in this step, since the SI message list may be notified to the network-side device through Msg1 or Msg3, step 605 may be started before or after step 604 is ended;

step 606, the RRC layer of the ue stops the timer T after receiving the requested SI message.

Step 607, the user terminal RRC layer informs the MAC layer to stop the RACH procedure.

if the MAC layer fails to initiate the random access process for the Mth time, the MAC layer reports a random access process failure message to the RRC layer, and the MAC layer terminates the random access process, wherein M is an integer greater than or equal to 1;

and the RRC layer does not receive the system information returned by the base station, considers that the system information acquisition fails according to the random access process failure message and terminates the timer.

Wherein, the M may be notified to the user terminal by the base station through a broadcast or dedicated RRC message.

In this embodiment, when the number of times of failure in the random access procedure reaches M times, the RRC terminates the timer and considers that the system information acquisition is failed, so that power consumption of the user terminal can be reduced.

For example: as shown in fig. 7:

step 701, the RRC layer of the ue initiates a system request procedure, and starts a timer T, where the length of the timer T may be MSI notification or protocol specification or other manners.

step 702, the MAC layer of the ue initiates a random access RACH procedure according to the RRC layer trigger, and the RACH procedure fails for the first time (dashed box).

Step 703, after the MAC layer of the ue performs M-1 attempts, the MAC layer fails to re-initiate the RACH procedure (M-th failure).

Step 703a, after the mth failure, the MAC layer of the ue reports an RACH procedure failure message to the RRC layer.

Here, M may be configured by RRC of the user terminal UE, and the configuration parameter of RRC may be from broadcast or dedicated configuration of the network. In addition, the RACH procedure failure message may also be referred to as a RACH procedure failure indication.

After receiving the RACH failure message, the RRC layer of the user terminal terminates the timer T, and considers that the system message request process has failed, and the RRC layer does not need to process the system information, so as to save power consumption of the user terminal.

if the random access process initiated by the MAC layer fails, the MAC layer initiates the random access process again;

The above-mentioned re-initiating the random access procedure by the MAC may be performed within a valid period of the timer if the random access procedure initiated by the MAC layer fails, or it may be understood that the above-mentioned re-initiating the random access procedure by the MAC is performed before the timer expires if the random access procedure initiated by the MAC layer fails.

In this embodiment, before the timer expires, the RRC layer receives the system information sent by the base station, and when the random access procedure fails, the RRC layer notifies the MAC layer to stop the random access procedure, so as to reduce power consumption of the ue. For example: as shown in fig. 8, the method comprises the following steps:

step 801, the RRC layer of the user terminal initiates a system request procedure, and starts a timer T, where the length of the timer T may be MSI notification or protocol specification or other manners.

step 802, the MAC layer of the ue initiates a random access RACH procedure according to the RRC layer trigger, and the RACH procedure fails for the first time (dashed box).

Step 803, the MAC layer of the user terminal re-initiates the RACH procedure, which fails.

Step 804, after receiving the requested SI message, the RRC layer of the ue stops the timer T.

Step 805, the user terminal RRC layer informs the MAC layer to stop the RACH procedure.

The SI message received by the UE may be a network broadcast message triggered by SI requests of other UEs, and step 804 may occur at any time, for example, before step 802. If step 804 occurs after step 801, the user terminal may terminate the timer T, informing the MAC to stop the RACH procedure, upon receipt of step 804.

and the RRC layer receives the random access process success message fed back by the MAC layer, and the RRC layer does not receive the system information returned by the base station, the timer is terminated, the system information request sent to the base station by the user terminal is considered to be successfully sent, and the base station successfully receives the system information request.

In this embodiment, if the RRC receives the random access procedure success message fed back by the MAC, the timer may be terminated, and the system information request procedure may be considered to be successful, so that power consumption of the ue may be reduced. For example: as shown in fig. 9, the method comprises the following steps:

step 901, the RRC layer of the ue initiates a system request procedure, and starts a timer T, where the length of the timer T may be MSI notification or protocol specification or other manners.

step 902, the MAC layer of the ue initiates a random access RACH procedure according to the RRC layer trigger, and the RACH procedure fails for the first time (dashed box).

Step 903, when the MAC layer of the user terminal performs the X-th attempt, the RACH of the MAC layer is successful.

Where X is less than N or M in the above examples.

Step 903a, the MAC layer of the user terminal reports a RACH process success message to the RRC layer; after the RRC layer of the user terminal receives the RACH success message, the timer T is terminated, and the system message request process is successful.

It should be noted that, in this embodiment of the present invention, if the system information request is Msg1 in a random access process, the random access process success message may indicate that the MAC layer successfully receives Msg2 in the random access process, and confirms that the Msg2 carries an identifier of a preamble in the Msg1, that is, the random access process success means that the MAC layer successfully receives Msg2 in the random access process, and confirms that the Msg2 and the Msg2 are responses to the Msg 1; or

The system information request is Msg3 in a random access process, and the random access process success message may indicate that the MAC layer successfully receives Msg4 in the random access process, and confirms that the Msg4 carries bit information at a preset position in the Msg3, that is, the random access process success means that the MAC layer successfully receives Msg4 in the random access process, and confirms that the Msg4 carries bit information at a preset position in the Msg 3.

By confirming that the Msg2 is a response to the Msg1 or confirming that the Msg4 is a response to the Msg3, the accuracy of the random access procedure success message can be improved, and the performance of the user terminal can be improved.

It should be noted that, in the embodiment of the present invention, the system information request is Msg1 in the random access process, and the random access process failure message indicates that the MAC layer does not successfully receive Msg2 in the random access process, that is, the random access process failure means that the MAC layer does not successfully receive Msg2 in the random access process; or

And if the system information request is Msg3 in the random access process, the random access process failure message indicates that the MAC layer does not successfully receive Msg4 in the random access process, i.e., the random access process failure means that the MAC layer does not successfully receive Msg4 in the random access process.

It should be noted that, in this embodiment of the present invention, notifying the MAC layer to stop the random access process may include: and informing the MAC layer of resetting. Wherein, the storage space of the user terminal can be saved by notifying the reset of the MAC layer, because after the reset of the MAC layer, the related information of the MAC layer about the requested system information does not need to be stored.
