Description
Technical Field
The present application relates to the field of communications, and in particular, to a data processing method and a terminal device.
Background
Currently, both LTE (Long Term Evolution) and NR (New Radio) UEs (User Equipment) Report BSRs (Buffer Status Report). In the LTE system, the basic uplink scheduling is as follows: when the UE has uplink data to send, the UE sends an SR on a specified SR (scheduling Request) resource. And when the base station receives the scheduling request of the UE, the base station knows that the UE has uplink data to be sent, and the base station schedules the UE to send the uplink data. The UE sends BSR and possible partial data on the uplink authorization of the base station, the base station knows how much uplink data the UE has according to the BSR, and then the base station can schedule data according to how much uplink data the UE has and the priority of the data service.
BSR reporting is triggered when the following events occur:
1. the uplink data buffer (i.e. buffer) of the UE is empty and new data arrives: when all Logical channels of all LCGs (Logical Channel groups) do not have uplink data that can be sent, if any Logical Channel belonging to any one LCG has data that can be sent, the UE triggers BSR reporting. For example: the UE transmits uplink data for the first time. This BSR is called "Regular BSR".
2. High priority data arrival: if the UE has already sent a BSR and is waiting for a UL grant (uplink scheduling grant), where there is higher priority data to be transmitted, the UE triggers BSR reporting, which is called "Regular BSR".
3. The UE periodically updates its buffer status to the eNodeB (evolved Node B). This BSR is called "Periodic BSR".
4. The eNodeB configures a retransmission timer for the UE, and triggers the BSR when the timer expires and there is data available to send in any logical channel of any LCG of the UE. This BSR is referred to as the "Regular BSR".
5. When the UE has uplink resources and finds that the data to be transmitted is not enough to fill the resources, the redundant bits are equal to or larger than the size of the BSR and its subheader, and the UE uses the bits to transmit the BSR. This BSR is called "Padding BSR (piggyback BSR)".
The triggered BSR has a cancellation mechanism, and if a UL grant for the UE can load all data and the UL grant cannot additionally load the BSR and its subheader, the triggered BSR is cancelled.
Currently, if a Regular BSR is triggered, at the same time the UE triggers an SR if it has no uplink scheduling resources available. If the UE is not configured with SR resources, the UE triggers a RACH (Random Access Channel). The SR carried on PUCCH (Physical Uplink Control Channel) is a proprietary SR, and the triggered RACH is a non-proprietary SR. After the proprietary SR is triggered, if the BSR triggering the proprietary SR is already included in the uplink transmission, the proprietary SR is cancelled.
However, in the current standard development process, there are many situations that have not been related, for example, how to handle the triggered BSR after an RRC (Radio Resource Control) has triggered a BSR by a system information request, but the BSR corresponding to the request has not been transmitted. It can be seen that the above cancellation mechanism for BSR is not yet perfect.

Fig. 1 is a flow chart of a data processing method in an embodiment of the present application. The method of fig. 1 is performed by a terminal device and may include:
step S101, at least one system information request is triggered by the radio resource control layer RRC.
Step S102, if the system information requests triggering of the related data and the related data is not sent, determining whether the RRC meets a preset condition.
The related data may include a buffer status report BSR, a scheduling request SR triggered by the buffer status report BSR, and may further include system information request data corresponding to the system information request and transmitted from the radio resource control layer RRC to the lower layer. The lower layer comprises at least one of a packet data convergence protocol layer PDCP, a radio link control layer RLC, a medium access control layer MAC.
Step S103, when it is determined that the radio resource control layer RRC satisfies the preset condition, canceling the related data, or notifying the lower layer of canceling the related data.
In the embodiment of the application, at least one system information request is triggered by a Radio Resource Control (RRC) layer, and if the system information request triggers related data and the related data are not sent, whether the RRC layer meets a preset condition is determined; and then when the RRC is determined to meet the preset condition, canceling the related data, or informing the lower layer to cancel the related data. Therefore, the technical scheme can determine whether to cancel the related data or not under the condition that the system information request triggers the related data but the related data is not sent yet, thereby perfecting a BSR cancellation mechanism and further perfecting UE behaviors.
The method of the embodiments of the present application will be further described with reference to specific embodiments.
In one embodiment, the preset conditions include at least one of:
(1) the radio resource control layer RRC cancels the system information request.
(2) And the radio resource control layer RRC receives system information corresponding to the system information request.
For example, the radio resource control layer RRC receives the broadcast message and demodulates part or all of the triggered system information from the broadcast message.
(3) The radio resource control layer RRC receives a bitmap (i.e., bitmap) corresponding to the system information to be broadcasted.
That is, when the system information request triggers related data and the related data is not transmitted, the radio resource control layer RRC cancels the related data or notifies the lower layer of canceling the related data if the radio resource control layer RRC satisfies the at least one preset condition.
In this embodiment, the terminal device can cancel the relevant data or notify the lower layer to cancel the relevant data when the radio resource control layer RRC cancels the system information request, receives the system information corresponding to the system information request, or receives the bitmap corresponding to the system information to be broadcasted, so that the terminal device can cancel the triggered relevant data, such as the buffer status report BSR, the scheduling request SR triggered by the buffer status report BSR, and the like, under any condition, thereby perfecting the cancellation mechanism of the buffer status report BSR and further perfecting the UE behavior.
In one embodiment, the relevant data includes a buffer status report BSR. Before notifying the lower layer of cancelling the relevant data (i.e. cancelling the buffer status report BSR), it may also be determined whether other data exists on the logical channel for sending the system information request, and if it is determined that other data does not exist on the logical channel for sending the system information request, the MAC of the MAC layer is notified to cancel the buffer status report BSR.
In this embodiment, when it is determined that the radio resource control layer RRC satisfies the preset condition and no other data exists on the logical channel for sending the system information request, the MAC of the MAC layer is notified to cancel the BSR. Since the radio resource control layer RRC does not need to report the buffer status report BSR when the preset condition is satisfied and there is no other data on the logical channel for sending the system information request, canceling the buffer status report BSR in this case makes the UE behavior more perfect, and avoids unnecessary data occupying the logical channel.
In one embodiment, the relevant data includes a buffer status report BSR. Before notifying the lower layer of cancelling the relevant data (i.e. cancelling the buffer status report BSR), it may also be determined whether data is generated on other logical channels having priorities equal to or lower than the logical channel used for sending the system information request, and if it is determined that no data is generated on other logical channels having priorities equal to or lower than the logical channel, the MAC of the MAC layer is notified to cancel the buffer status report BSR.
In another embodiment, when it is determined that the radio resource control layer RRC satisfies the preset condition and no other data exists on the logical channel for sending the system information request, it may further determine whether data is generated on another logical channel having a priority equal to or lower than that of the logical channel (the logical channel is used for sending the system information request), and notify the MAC to cancel the BSR if it is determined that no data is generated on another logical channel having a priority equal to or lower than that of the logical channel.
In the above embodiment, the MAC of the MAC layer can be notified to cancel the BSR when it is determined that the RRC of the radio resource control layer satisfies the preset condition or when it is determined that the RRC of the radio resource control layer satisfies the preset condition and there is no other data on the logical channel for sending the system information request. Since the buffer status report BSR does not need to be reported in any case, the cancellation of the buffer status report BSR in the two cases makes the UE behavior more perfect, and avoids unnecessary data occupying the logical channel.
In one embodiment, the relevant data further comprises a scheduling request SR triggered by the buffer status report BSR. That is, the relevant data includes a buffer status report BSR triggered by a system information request and a scheduling request SR triggered by the buffer status report BSR. Therefore, in this embodiment, after notifying the MAC of the MAC to cancel the BSR, if the scheduling request SR is not sent, the scheduling request SR is cancelled. Since the scheduling request SR is triggered by the buffer status report BSR at the MAC of the MAC layer, the scheduling request SR is cancelled directly at the MAC of the MAC layer.
In this embodiment, when it is determined that the radio resource control layer RRC satisfies the preset condition, the MAC of the MAC is notified to cancel the buffer status report BSR, and the scheduling request SR triggered by the buffer status report BSR is directly cancelled at the MAC of the MAC. When the radio resource control layer RRC meets the preset condition, there is no need to report the buffer status report BSR and uplink transmission of the scheduling request SR, so the cancellation of the buffer status report BSR and the scheduling request SR in this case makes the UE behavior more perfect, avoids unnecessary data occupying a logical channel, and avoids the terminal device from uplink transmission of invalid data.
In one embodiment, the related data includes system information request data corresponding to the system information request, which is transmitted to the lower layer by the radio resource control layer RRC. And when the radio resource control layer RRC is determined to meet the preset conditions, deleting the system information request data, or informing a lower layer to delete the system information request data.
Wherein the system information request data may include at least one of:
(1) data corresponding to the system information request, such as PDCP SDU and/or PDCP PDU, transferred between the radio link control layer RLC and the packet data convergence protocol layer PDCP; specifically, if the system information request data is not processed by the packet data convergence protocol layer PDCP, the system information request data includes PDCP SDU; if the system information request data has been processed by the packet data convergence protocol layer PDCP, the system information request data includes PDCP PDUs.
(2) Data and/or data segments corresponding to system information requests, such as RLC SDU and/or segments, RLC PDU, transmitted between the radio link control layer RLC and the medium access control layer MAC.
(3) Buffered data for message 3 (i.e., Msg 3).
In this embodiment, the system information request data can be deleted when it is determined that the radio resource control layer RRC satisfies the preset condition. Since the RRC layer does not need the system information request data when the RRC layer satisfies the predetermined condition, deleting the system information request data in this case can avoid unnecessary data occupying the logical channel.
For any of the above embodiments, when the system information request triggers related data and the related data is not sent, the related data may be marked. The timing of the marking may be after determining whether the radio resource control layer RRC satisfies the preset condition and before canceling the related data or notifying the lower layer of canceling the related data, or before determining whether the radio resource control layer RRC satisfies the preset condition. Thus, when the related data is cancelled or the lower layer is notified to cancel the related data, the related data to be cancelled (namely, the marked related data) can be determined according to the mark, and then the marked related data is cancelled or the lower layer is notified to cancel the marked related data. In this embodiment, marking the related data can distinguish the related data from other data, thereby avoiding that the terminal device cancels other data when cancelling the related data.
It should be noted that the marking of the relevant data is only used inside the terminal device, and does not affect the actually transmitted message.
The data processing method provided by the application is explained by two specific embodiments.
Example one
Fig. 2 is a flowchart of a data processing method according to a first embodiment. In this embodiment, the related data includes a buffer status report BSR and a scheduling request SR triggered by the buffer status report BSR. The method of fig. 2 is performed by a terminal device and may include:
step S201, at least one system information request is triggered by the radio resource control layer RRC.
Wherein, the system information request is the SI request.
Step S202, when the system information request triggers the buffer status report BSR and the buffer status report BSR is not sent, the radio resource control layer RRC marks the buffer status report BSR and the scheduling request SR.
It should be noted that the marking of the buffer status report BSR is only used in the terminal device, and does not affect the actually transmitted message.
Step S203, the radio resource control layer RRC monitors whether a preset condition is satisfied. If yes, go to step S204; if not, the monitoring is continued.
Wherein the preset condition comprises at least one of the following conditions: the radio resource control layer RRC cancels the system information request, the radio resource control layer RRC receives the system information corresponding to the system information request, and the radio resource control layer RRC receives the bitmap (i.e. bitmap) corresponding to the system information to be broadcasted.
Step S204, it is determined that no other data exists on the logical channel for transmitting the system information request, and it is determined that no data is generated on the other logical channel having the priority equal to or lower than the logical channel.
Step S205, the radio resource control layer RRC notifies the MAC to cancel the buffer status report BSR with the flag.
In step S206, if the scheduling request SR triggered by the buffer status report BSR is not sent, the scheduling request SR with the flag is cancelled.
In this embodiment, when it is determined that the radio resource control layer RRC meets the preset condition, the MAC is notified to cancel the buffer status report BSR, and the scheduling request SR triggered by the buffer status report BSR is directly cancelled at the MAC. When the radio resource control layer RRC meets the preset condition, there is no need to report the buffer status report BSR and uplink transmission of the scheduling request SR, so the cancellation of the buffer status report BSR and the scheduling request SR in this case makes the UE behavior more perfect, avoids unnecessary data occupying a logical channel, and avoids the terminal device from uplink transmission of invalid data.
Example two
Fig. 3 is a flowchart of a data processing method according to a second embodiment. In the second embodiment, the related data includes system information request data corresponding to the system information request and transmitted from the radio resource control layer RRC to the lower layer. The method of fig. 3 is performed by a terminal device and may include:
step S301, the radio resource control layer RRC triggers at least one system information request, and transmits system information request data corresponding to the system information request to a lower layer.
Wherein, the system information request is the SI request. The lower layer comprises at least one of a packet data convergence protocol layer PDCP, a radio link control layer RLC, a medium access control layer MAC.
The system information request data may include at least one of: (1) data corresponding to the system information request, such as PDCP SDU and/or PDCP PDU, transferred between the radio link control layer RLC and the packet data convergence protocol layer PDCP; specifically, if the system information request data is not processed by the packet data convergence protocol layer PDCP, the system information request data includes PDCP SDU; if the system information request data has been processed by the packet data convergence protocol layer PDCP, the system information request data includes PDCP PDUs. (2) Data and/or data segments corresponding to system information requests, such as RLC SDU and/or segments, RLC PDU, transmitted between the radio link control layer RLC and the medium access control layer MAC. (3) Buffered data for message 3 (i.e., Msg 3).
Step S302, the radio resource control layer RRC marks the system information request data.
In this step, the marked object may include at least one of PDCP SDUs, PDCP PDUs, RLC SDUs and/or segments, RLC PDUs, buffered data of message 3 (i.e., Msg 3).
It should be noted that the marking of the system information request data is only used inside the terminal device, and does not affect the actually transmitted message.
Step S303, the radio resource control layer RRC monitors whether a preset condition is satisfied. If yes, go to step S304; if not, the monitoring is continued.
Wherein the preset condition comprises at least one of the following conditions: the radio resource control layer RRC cancels the system information request, the radio resource control layer RRC receives the system information corresponding to the system information request, and the radio resource control layer RRC receives the bitmap (i.e. bitmap) corresponding to the system information to be broadcasted.
Step S304, the lower layer is informed to delete the system information request data with the marks.
In the second embodiment, the system information request data can be deleted when it is determined that the radio resource control layer RRC satisfies the preset condition. Since the RRC layer does not need the system information request data when the RRC layer satisfies the predetermined condition, deleting the system information request data in this case can avoid unnecessary data occupying the logical channel.
