Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a data transmission method and a user terminal.
Background
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, some bearers of a UE (User Equipment) can be respectively transmitted in the MeNB and the SeNB, in the figure, an MCG Bearer is a primary cell group Bearer, a SplitBearer is a split Bearer, and an SCG Bearer is a secondary cell group Bearer.
In the discussion of the NR (new Radio) of 5G (fifth generation mobile communication technology), due to the requirement of high reliability service, 3GPP (third generation partnership project) has agreed that in order to better ensure the reliability of service transmission, PDUs (Protocol Data units) of the same PDCP may 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 (user equipment) of LTE and NR reports BSR, and in an LTE system, a 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 a base station (eNB) receives a scheduling request of UE, the base station knows that the UE has uplink data to send, the base station schedules the UE to send 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 the base station can schedule data according to how much uplink data the UE has and the priority of 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.
Currently, BSRs are reported according to Logical Channel groups, the Logical Channel groups of UEs are divided into at most 4 groups, and there are two BSR formats, as shown in fig. 4 and 5, Short BSRs (Short BSRs) and Truncated BSRs (Truncated BSRs) MAC CEs report buffers of the highest priority LCGs (Logical Channel groups) with data, Long BSRs (Long BSRs) MAC CEs report buffers of all 4 Logical Channel groups, in the figure, the LCG IDs represent Logical Channel Group identifiers, Buffer sizes represent Buffer sizes, and Oct represents octaves.
3) RACH (random access channel) resource request procedure:
if the UE has uplink data to send but the UE does not configure SR resources, the UE triggers RACH process to request uplink resources.
4) 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.
5) NR (New Radio, New wireless) BandWidth Part (partial BandWidth, hereinafter referred to as BWP):
aiming at the background that the NR system side adopts large BandWidth transmission (such as 100MHz and 400MHz), because the terminals have different BandWidth capabilities, the concept of BandWidth Part is introduced, so that the terminals with small BandWidth capability can access a Part of BandWidth in a large BandWidth network, which is called BandWidth Part. Some design conclusions about BWP for NR are as follows:
(1) one UE may be configured with one or more BWPs.
When the UE is configured with multiple BWPs, each BWP may employ the same or different numerologies (baseband parameters).
(2) DL and UL bandwidth part of one UE can be configured separately by the network.
(3) The UE may be activated one (Rel-15) or more (later released) BWPs.
(4) The UE can perform BWP adjustment according to the instruction of L1/L2 signaling, including:
referring to fig. 6 to 8, application scenarios of three BWPs are shown. If the UE cannot support all numerologies of the cell, the corresponding band may be avoided from being configured to the UE when the BWP is configured for the UE. The network configures the available BWP set of each cell for the UE through RRC signaling, and then dynamically activates and deactivates the BWP to be started through L1/L2 signaling. In one cell, the network may activate one or more BWPs simultaneously, where overlallcarrier denotes all carriers.
Thus, when the logical channel is deactivated, it may cause a waste of resources and unnecessary restriction of data transmission.

Referring to fig. 9, a flow of a data transmission method in an embodiment of the present invention is shown in the drawing, where an execution subject of the method is a UE, and the method includes the following specific steps:
optionally, the determining of the logical channel deactivation includes:
the first method is to receive a command indicating the deactivation of a logical channel from a network side, for example: receiving a first deactivation command which is sent by a network side and indicates a secondary cell of the UE, wherein the secondary cell bears the data of the logical channel; or, receiving a second deactivation command of PDCP (packet data convergence protocol) duplicate data sent by the network side, where the second deactivation command is used to instruct the UE to stop sending the PDCP duplicate data on the logical channel.

In this way, after determining that the logical channel is deactivated, the UE cancels the SR correspondingly triggered by the BSR triggered by the logical channel, or cancels the RACH correspondingly triggered by the BSR triggered by the logical channel, thereby reducing unnecessary data transmission and avoiding resource waste; or canceling the LCP restriction of the logic channel priority corresponding to the logic channel to ensure reasonable data transmission and reduce unnecessary data transmission restriction.
Referring to fig. 10, a flow of a data transmission method in another embodiment of the present invention is shown, where an execution subject of the method is a UE, and the method includes the following specific steps:
optionally, determining the logical channel deactivation manner includes:
the first method is to receive a command indicating the deactivation of a logical channel from a network side, for example: receiving a first deactivation command which is sent by a network side and indicates a secondary cell of the UE, wherein the secondary cell bears the data of the logical channel; or, receiving a second deactivation command of PDCP (packet data convergence protocol) duplicate data sent by the network side, where the second deactivation command is used to instruct the UE to stop sending the PDCP duplicate data on the logical channel.
In the second way, the logical channel deactivation is determined according to a preset rule, for example, the preset deactivation timer expires, but is not limited thereto.
and 1003, keeping the buffer status report BSR triggered by the logical channel.
It should be noted that, in this embodiment, the order of step 1002 and step 1003 is not limited.
In the embodiment of the present invention, if BSR is triggered (trigger), when the UE has no available UL (uplink) resource and the UE has configured SR resource, the UE triggers SR.
When the corresponding logical channel cannot transmit data due to the Scell (secondary cell) being deactivated or the PDCP duplication being deactivated, the BSR triggered by the logical channel is not cancelled, that is, the triggered BSR is maintained, but the SR triggered by the BSR is cancelled, or the RACH triggered by the BSR is cancelled. Further, the triggered BSR does not trigger a new SR or trigger a new RACH either. When the UE receives the uplink grant of the base station, the UE can send the BSR to the base station.
In this way, after determining that the logical channel is deactivated, the UE cancels the SR correspondingly triggered by the BSR triggered by the logical channel, or cancels the RACH correspondingly triggered by the BSR triggered by the logical channel, thereby reducing unnecessary data transmission and avoiding resource waste.
Referring to fig. 11, a flow of a data transmission method in another embodiment of the present invention is shown, where an execution subject of the method is a UE, and the method includes the following specific steps:
optionally, the determining of the logical channel deactivation includes:
the first method is to receive a command indicating the deactivation of a logical channel from a network side, for example: receiving a first deactivation command which is sent by a network side and indicates a secondary cell of the UE, wherein the secondary cell bears the data of the logical channel; or, receiving a second deactivation command of PDCP (packet data convergence protocol) duplicate data sent by the network side, where the second deactivation command is used to instruct the UE to stop sending the PDCP duplicate data on the logical channel.
In the second way, the logical channel deactivation is determined according to a preset rule, for example, the preset deactivation timer expires, but is not limited thereto.
and 1104, when receiving an uplink grant sent by the network side, sending the BSR to the network side according to the priority of the BSR triggered by the logical channel.
It should be noted that, in the embodiment of the present invention, the order of step 1102 and step 1103 is not limited.
In this way, after determining that the logical channel is deactivated, the UE cancels the SR correspondingly triggered by the BSR triggered by the logical channel, thereby reducing unnecessary data transmission and avoiding resource waste.
Referring to fig. 12, a flow of a data transmission method in another embodiment of the present invention is shown, where an execution subject of the method is a UE, and the method includes the following specific steps:
optionally, the determining of the logical channel deactivation includes:
the first method is to receive a command indicating the deactivation of a logical channel from a network side, for example: receiving a first deactivation command which is sent by a network side and indicates a secondary cell of the UE, wherein the secondary cell bears the data of the logical channel; or, receiving a second deactivation command of PDCP (packet data convergence protocol) duplicate data sent by the network side, where the second deactivation command is used to instruct the UE to stop sending the PDCP duplicate data on the logical channel.
In the second way, the logical channel deactivation is determined according to a preset rule, for example, the preset deactivation timer expires, but is not limited thereto.
In the embodiment of the present invention, if the BSR is triggered, after the corresponding logical channel is deactivated due to Scell deactivation or PDCP duplicate deactivation and cannot transmit data, the BSR triggered by the logical channel is not cancelled, that is, the triggered BSR is maintained, and the priority of the BSR is reduced to that of a padding BSR when the BSR is reported, that is, when the UE receives the uplink grant of the base station, the BSR is carried only when resources are left after the data transmission.
In this way, after determining that the logical channel is deactivated, the UE cancels the SR correspondingly triggered by the BSR triggered by the logical channel, thereby reducing unnecessary data transmission and avoiding resource waste.
Referring to fig. 13, a flow of a data transmission method in another embodiment of the present invention is shown, where an execution subject of the method is a UE, and the method includes the following specific steps:
optionally, the determining of the logical channel deactivation includes:
the first method is to receive a command indicating the deactivation of a logical channel from a network side, for example: receiving a first deactivation command which is sent by a network side and indicates a secondary cell of the UE, wherein the secondary cell bears the data of the logical channel; or, receiving a second deactivation command of PDCP (packet data convergence protocol) duplicate data sent by the network side, where the second deactivation command is used to instruct the UE to stop sending the PDCP duplicate data on the logical channel.
In the second way, the logical channel deactivation is determined according to a preset rule, for example, the preset deactivation timer expires, but is not limited thereto.
In the embodiment of the present invention, if the BSR is triggered, after the corresponding logical channel is deactivated due to scell or the PDCP duplicate is deactivated and cannot transmit data, the BSR triggered by the logical channel is not cancelled, that is, the triggered BSR is maintained, and the priority of the BSR is reduced to the priority of the BSR truncation when the BSR is reported, that is, when the UE receives the uplink grant of the base station, if there is a remaining resource to send the BSR, if there is a BS of another logical channel to report, the BS information of the another logical channel is preferentially reported.
In this way, after determining that the logical channel is deactivated, the UE cancels the SR correspondingly triggered by the BSR triggered by the logical channel, thereby reducing unnecessary data transmission and avoiding resource waste.
Referring to fig. 14, a flow of a data transmission method in another embodiment of the present invention is shown, where an execution subject of the method is a UE, and the method includes the following specific steps:
optionally, the determining of the logical channel deactivation includes:

In the second way, the logical channel deactivation is determined according to a preset rule, for example, the preset deactivation timer expires, but is not limited thereto.
And 1402, canceling LCP limitation corresponding to the logical channel.
In the embodiment of the present invention, when the corresponding logical channel is deactivated due to the Scell or BWP carrying the logical channel, and the logical channel is restricted by the LCP to be sent only on the Scells or BWPs, the corresponding LCP restriction is cancelled.
Such as: the Scell1 or BWP1 is a short TTI carrier, and the network configuration UE LCH1 (logical channel 1) can only map on this carrier of the Scell1 or BWP1 of one cell. That is, uplink data of the UE can be transmitted only on the Scell1 or BWP1 of one cell due to the limitation of LCP. When Scell1 or BWP1 is deactivated, the UE cancels LCP restriction that LCH1 can only send on the carrier of Scell1 or BWP1 of one cell.
Therefore, after the UE determines that the logical channel is deactivated, the logical channel priority LCP limitation corresponding to the logical channel is cancelled, so that reasonable data sending is ensured, and unnecessary data sending limitation is reduced.
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.
