Description

BSR cancellation method and user terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for cancelling a Buffer Status Report (BSR) and a user terminal.

Background

1) PDCP (Packet Data Convergence Protocol) replication function:

currently, in a Long Term Evolution (LTE) system, a dc (dual connectivity) dual connectivity function is introduced, and a protocol stack of the dual connectivity function is shown in fig. 1, where a MeNB (macro base station) and a SeNB (auxiliary base station) are respectively a primary and a secondary base stations, and some bearers of a UE (User Equipment) can be respectively transmitted in the MeNB and the SeNB.

In the discussion of the NR (new Radio) of 5G (fifth generation mobile communication technology), due to the requirement of high reliability service, 3GPP has agreed that in order to better ensure the reliability of service transmission, PDUs (Protocol Data units) of the same PDCP under DC can be mapped to logical channels of different base stations and transmitted.

In a CA (carrier aggregation) scenario, PDUs of the same PDCP may be mapped to different logical channels and transmitted on different carriers. Such mapping of logical channels and carriers is configured by RRC (Radio Resource Control).

The RAN 298 has agreed to activate or deactivate transmission of PDCP duty with a MAC (medium access Control) CE (Control Element) over the conference. For CA, the PDCP maps different logical channels to which the new data packet and the duplicate data packet are mapped, respectively, to different RLC (Radio Link Control) entities for transmission, as shown in fig. 2. RLC is an independent entity for the DC case, as is MAC.

2) BSR trigger and cancel function:

currently, UE of LTE and NR will report BSR, and in an LTE system, the basic uplink scheduling is as shown in fig. 3: when the UE has uplink data to send, the UE sends an SR on a specified SR (scheduling Request) resource. When the base station receives a scheduling request of the UE, the base station knows that the UE has uplink data to be sent, the base station schedules the UE to send the uplink data, the UE sends BSR and possible partial data on uplink grant (grant) of the base station, and the base station knows how much uplink data the UE has according to the BSR and then can schedule the data according to how much uplink data the UE has and the priority of the data service. It can be seen that the role of the BSR is information that the UE tells the base station how much data the UE has to send.

Wherein, the trigger of the BSR has a cancellation mechanism, and if a UL grant (uplink grant) assigned to the UE can load all data and the UL grant cannot additionally load the BSR and the subheader of the BSR, the BSR trigger is cancelled.

3) LCP (Logical Channel Priority) procedure:

the LCP procedure is a method in which the UE performs assembly for uplink data transmission according to uplink priority, and currently, in NR, according to service requirements, it may be required that a certain logical channel is mapped on only one type of carrier.

There is currently no discussion that the PDCP duty data-triggered BSR is cancelled due to activation or deactivation of the PDCP duty. However, if the triggered BSR is not cancelled, unnecessary waste of resources is caused.

Referring to fig. 4, a flow of a BSR cancellation method provided in the embodiment of the present invention is shown in the figure, where an execution main body of the method may be a UE, and the specific steps are as follows:

step 401, receiving a command indicating that the first logical channel deactivates or stops sending data;

in the embodiment of the present invention, the UE may send data to the network side through two logical channels, for example, the first logical channel transmits PDCP duplicate data, and the second logical channel transmits initial data, or the UE sends data to the network side through one logical channel, for example, the first logical channel transmits non-PDCP duplicate data, which may be data of an LCH.

For example, the UE receives a command indicating that the network side deactivates or stops sending data on the first logical channel, where the data may be PDCP duplicate data or non-PDCP duplicate data.

And step 402, canceling the BSR triggered by the first logic channel according to the command.

In the embodiment of the present invention, if the BSR triggered by the first logical channel is cancelled, the corresponding SR may be further cancelled.

In this way, after receiving the command indicating that the first logical channel deactivates or stops transmitting data, the UE can stop transmitting data on the first logical channel according to the command and cancel the BSR triggered by the first logical channel, thereby reducing unnecessary transmission.

Referring to fig. 5, a flow of a BSR cancellation method provided in the embodiment of the present invention is shown, where an execution main body of the method may be a UE, and the specific steps are as follows:

step 501, configuring to transmit PDCP duplicate data on the first logical channel, and transmitting initial data on a second logical channel.

It should be noted that the step 501 is an optional step.

Referring to fig. 6, in which LCH1 denotes a first logical channel and LCH2 denotes a second logical channel. The UE triggers a BSR due to data coming on LCH 1.

Step 502, receiving a first deactivation command of PDCP duplication data sent by the network side, where the first deactivation command is used to instruct the UE to stop sending PDCP duplication data on the first logical channel.

Note that, at this time, the UE keeps transmitting on the second logical channel.

Step 503, canceling the BSR triggered by the first logical channel according to the first deactivation command.

Step 504, the BSR triggered by the second logical channel is cancelled, or the BSR triggered by the radio data bearer corresponding to the second logical channel is cancelled.

It should be noted that the step 504 is an optional step.

In the embodiment of the present invention, if the BSR triggered by the first logical channel is cancelled, the corresponding SR may be further cancelled. That is, after the corresponding BSR is triggered, the SR is triggered if there is no uplink resource. If the BSR is cancelled, an SR corresponding to the BSR is determined and the SR is cancelled.

In this way, after receiving the first deactivation command indicating that the first logical channel deactivates or stops sending the PDCP duplicate data, the UE can stop sending the PDCP duplicate data on the first logical channel according to the first deactivation command, cancel the BSR triggered by the first logical channel, and further cancel the BSR triggered by the second logical channel, or cancel the BSR triggered by the radio data bearer corresponding to the second logical channel, thereby reducing unnecessary sending.

Referring to fig. 7, a flow of a BSR cancellation method provided in the embodiment of the present invention is shown in the figure, where an execution main body of the method may be a UE, and the specific steps are as follows:

step 701, configuring to transmit PDCP duty data on the first logical channel, and transmit initial data on the second logical channel, where the first secondary cell carries the first logical channel data, and the second secondary cell carries the second logical channel data, and execute step 702 or step 704.

Referring to fig. 8, Scell of PDCP duty data of both LCHs is deactivated. Here, LCH1 denotes a first logical channel, LCH2 denotes a second logical channel, Scell1 denotes a first secondary cell, and Scell2 denotes a second secondary cell. The UE triggers a BSR due to data coming on LCH 1.

It should be noted that the step 701 is an optional step.

Step 702, receiving a second deactivation command of the first secondary cell sent by the network side, where the second deactivation command is used to indicate that the first secondary cell of the UE is deactivated, where the first secondary cell carries first logical channel data, and perform step 703.

Step 703, deactivating the first secondary cell according to the second deactivation command, and canceling the BSR triggered by the first logical channel and carried in the first secondary cell.

Step 704, receiving a third deactivation command of the second secondary cell sent by the network side, where the third deactivation command is used to indicate that the second secondary cell of the UE is deactivated, and performing step 705;

step 705, deactivating the second secondary cell according to the third deactivation command, and canceling the BSR triggered by the second logical channel carried in the second secondary cell, or canceling the BSR triggered by the radio data carrier corresponding to the second logical channel carried in the second secondary cell.

It should be noted that the

above steps

704 and 705 are optional steps.

In this way, after receiving the third deactivation command indicating that the first logical channel deactivates or stops sending the PDCP duplicate data, the UE can stop sending the PDCP duplicate data on the first logical channel according to the third deactivation command, and cancel the BSR triggered by the first logical channel, and may further cancel the BSR triggered by the second logical channel, or cancel the BSR triggered by the radio data bearer corresponding to the second logical channel, thereby reducing unnecessary sending.

Referring to fig. 9, a flow of a BSR cancellation method provided in the embodiment of the present invention is shown in the figure, where an execution main body of the method may be a UE, and the specific steps are as follows:

step 901, configuring data transmission on a first logical channel, where the first secondary cell carries data of the first logical channel.

It should be noted that the step 901 is an optional step. The first logical channel may carry PDCP duplicate data or non-PDCP duplicate data.

Referring to fig. 10, wherein LCH1 represents the first logical channel and Scell1 represents the first secondary cell. The UE triggers a BSR due to data coming on LCH 1.

Step 902, receiving a fourth deactivation command of the first secondary cell sent by the network side, where the fourth deactivation command is used to indicate that the first secondary cell of the UE is deactivated, where the first secondary cell carries first logical channel data;

step 903, deactivating the first secondary cell according to the fourth deactivation command, and canceling the BSR triggered by the first logical channel carried in the first secondary cell.

It is to be noted that the first logical channel (LCH1) needs to be transmitted on the first secondary cell (Scell1), possibly due to LCP limitations.

In this way, after receiving the fourth deactivation command indicating that the first logical channel deactivates or stops transmitting data, the UE can stop transmitting data on the first logical channel according to the fourth deactivation command and cancel the BSR triggered by the first logical channel, thereby reducing unnecessary transmission.

The embodiment of the invention also provides a user terminal, and as the principle of solving the problems of the user terminal is similar to the measuring method in the embodiment of the invention, the implementation of the user terminal can refer to the implementation of the method, and repeated parts are not described again.
