Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method for deactivating and activating a secondary cell group, a communications apparatus, and a related product.
Background
A deactivation and activation mechanism for a Secondary Cell Group (SCG) is planned to be introduced in the third generation partnership project (3 GPP) R17. It is understood that deactivation may also be referred to as suspend and activation may also be referred to as resume. Wherein, after the Secondary Cell Group (SCG) is set to be deactivated, the User Equipment (UE) cannot send and receive data through the SCG; when uplink data arrives, the UE may request the network to set the SCG to active.
In a current New Radio (NR) specification, for a repetitive and inactive split Data Radio Bearer (DRB) and a repetitive and unconfigured split DRB, a Packet Data Convergence Protocol (PDCP) entity associates two Radio Link Control (RLC) entities, and the two RLC entities are respectively located in an MCG and an SCG, where one of the two RLC entities is a primary RLC entity. When transmitting data, the UE sends a PDCP Protocol Data Unit (PDU) to the RLC through the PDCP according to the configured ul-data split threshold. Specifically, if the amount of data transmitted is less than the uplink data segmentation threshold, it is sent to the primary RLC entity, otherwise it is sent to any RLC entity.
For the repeatedly activated detached DRB, the UE transmits PDCP control (control) PDUs to the primary RLC entity through PDCP and repeatedly transmits PDCP data (data) PDUs to the respective RLC entities, where the PDCP entities associate two or more RLC entities. The primary RLC entity is configured by a Network (NW) through Radio Resource Control (RRC) signaling, and one DRB configures only one primary RLC.
Then, after the Secondary Cell Group (SCG) of the UE is set to be deactivated, the User Equipment (UE) cannot transmit and receive data through the SCG. Specifically, for the repeatedly inactivated detached DRB and the repeatedly unconfigured detached DRB, if the primary RLC entity is located in the SCG, the UE cannot normally transmit data with a data volume smaller than the uplink data segmentation threshold after the SCG is deactivated. For the detached DRB repeatedly activated, if the primary RLC entity is in SCG, the UE cannot normally transmit PDCP control PDUs after SCG deactivation.

Detailed Description
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, 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 application.
The terminal device (also called User Equipment (UE)) in the present application may be: terminal-side devices such as mobile phones, tablet personal computers (pcs), laptop computers (laptops), Personal Digital Assistants (PDAs), Mobile Internet Devices (MIDs), and wearable devices (webable devices).
The network device in the present application may be a device capable of communicating with the terminal device. The network device may be any device having a wireless transceiving function, including but not limited to a base station, and the base station includes a main base station and a secondary base station.
It is understood that deactivation in this application may also be referred to as suspend and activation may also be referred to as resume.
Referring to fig. 1, an embodiment of the present invention provides a Radio Link Control (RLC) configuration method, including:
step S100: the terminal device receives a first message sent by a network device, where the first message is used to instruct a Secondary Cell Group (SCG) to deactivate. It is to be understood that the network device may be a primary base station or a secondary base station.
Step S200: after receiving the first message, the terminal device configures a master Radio Link Control (RLC) entity in a Master Cell Group (MCG) under the condition that a DRB entity is initially configured in the SCG. And after receiving the first message, the terminal equipment deactivates the SCG. After the SCG is deactivated, the master RLC entity is configured in the MCG in case the master RLC entity is initially configured in the SCG.
Referring to fig. 2, the primary RLC with DRB detached is configured in the SCG for the initial configuration state of the primary RLC. Referring to fig. 3, after the SCG is deactivated, the terminal device configures the master RLC in the MCG.
Referring to fig. 2, after header compression and ciphering are performed on data to be transmitted by a PDCP of a user equipment, a PDCP Protocol Data Unit (PDU) is generated, and then a part of the generated PDCP PDU is transmitted to a main RLC entity, which is located in an SCG; and part of the data is sent to the RLC entity of the separated DRB in the MCG, and the data is sent through the MCG and the SCG, so that the throughput rate of the user data is improved. When transmitting data, the size of the data volume needs to be considered, specifically, the terminal device sends a PDCP Protocol Data Unit (PDU) to the RLC through the PDCP according to the configured ul-data split threshold. If the transmitted data quantity is less than the uplink data segmentation threshold, the data is sent to the main RLC entity, otherwise, the data is sent to any RLC entity. That is, if all the data amount is less than the uplink data split threshold (ul-data split threshold), all the data is transmitted to the primary RLC entity. It can be understood that the ul-data split threshold (ul-data split threshold) is set by the network device according to actual needs.
After the SCG is deactivated, the terminal device has already designated the main RLC in the MCG, please refer to fig. 3, after the data to be sent is subjected to header compression, ciphering and other processing by the PDCP of the user equipment, a PDCP Protocol Data Unit (PDU) is generated, and then the generated PDCP PDU is sent to the main RLC entity, which is located in the MCG. At this time, the data is sent through the MCG, and the data can be sent normally.
It is understood that the disjointed DRBs include repeatedly activated disjointed DRBs, repeatedly inactivated disjointed DRBs, and repeatedly unconfigured disjointed DRBs. That is, the configuration mode is suitable for various types of separated DRBs, so that the applicability is improved.
As can be seen from the above, in the embodiment of the present invention, after the SCG is deactivated, if the main RLC entity of the DRB is in the SCG, the terminal device reassigns one RLC in the MCG as the main RLC of the DRB. At this time, even if the SCG is in a deactivated state, the terminal device may transmit data through the master RLC in the MCG.
As can be seen from the above, the method for deactivating and activating the auxiliary cell group provided in the embodiment of the present invention enables the terminal device to continue sending data even when the SCG is in a deactivated state, improves transmission reliability and transmission efficiency, avoids the possibility of data transmission failure, and improves user experience.
It can be understood that, in the case that the terminal device transmits uplink data to the network device through the master cell group MCG after configuring the master RLC entity in the MCG, the uplink transmission of the terminal device to the MCG uses the maximum supportable transmit power. At this time, since the SCG is in the deactivated state, the terminal device cannot send data through the SCG, and therefore the terminal device can transmit data to the MCG by using all power, thereby speeding up transmission efficiency and further improving user experience.
As shown in fig. 4, which is a flowchart of a second embodiment of the present invention, the flowchart includes steps S100, S200, S300, and S400, where step 100 and step 200 are the same as the first embodiment, and are not repeated here, but include:
step S300: and the terminal equipment receives a second message from the network equipment, wherein the second message is used for indicating the SCG activation.
Step S400: and after receiving the second message, the terminal equipment configures the main RLC entity into initial configuration. After receiving the second message, the terminal device reactivates the SCG according to the instruction, and then may restore the primary RLC entity to the original initial configuration, that is, to the primary RLC configuration in the SCG.
That is, after the SCG is reactivated, the primary RLC entity of the detached DRB is restored to the original initial configuration, that is, the primary RLC entity of the detached DRB is restored to be in the SCG (shown in fig. 2).
It can be understood that, the master RLC entity is configured as an initial configuration, that is, the SCG is reactivated, and the master RLC is further configured such that after the SCG, in a case where the terminal device sends uplink data to the network device through the MCG and the SCG, uplink transmission from the terminal device to the MCG and the SCG shares the transmission power of the terminal device. After the SCG is activated, the terminal device may send data through the SCG and the MCG, so when the terminal device uploads data, power needs to be shared to ensure that the SCG and the MCG operate normally.
Please refer to fig. 5, which is a flowchart of a third embodiment of the present invention, including steps S100 and S200, wherein step S100 is the same as the first embodiment and is not repeated, except that step S200: and under the condition that a main RLC entity of the separated DRB is initially configured in the SCG and the MCG is configured with at least two RLC entities, the terminal equipment configures one of the RLC entities as the main RCL entity. That is, referring to fig. 6, when there are multiple RLC entities in the MCG, the terminal device needs to select one of the multiple RLC entities as the main RLC entity.
The terminal device may select an RLC entity with certain advantages as a main RLC entity, for example: the RLC entity of MCG, that is, the RLC entity used by MCG when the network moves back to the detached bearer according to Radio Resource Control (RRC) signaling configuration; this option facilitates fast configuration of the primary RLC entity by the terminal equipment. Or selecting the RLC entity with the best corresponding Carrier Component (CC) signal from the plurality of RLC entities in the MCG as the main RLC entity; the RLC entity with the best CC signal is beneficial to bring better experience to the client. Or selecting the corresponding RLC entity with the highest CC transmission success rate from a plurality of RLC entities in the MCG as a main RLC entity; the RLC entity with the highest success rate of CC transmission can improve transmission efficiency. Or selecting the RLC entity with the largest or smallest Logical Channel Identifier (LCID) from the plurality of RLC entities in the MCG as the main RLC entity; the selection is more convenient for the terminal equipment to carry out rapid configuration.
Referring to fig. 7, it is a flowchart of a fourth embodiment of the present invention, which includes steps S100, S200, S300, and S400, wherein steps S100, S300, and S400 are the same as those in the second embodiment, and step S200 is the same as step S200 in the third embodiment, and are not repeated.
As an improvement to any of the foregoing embodiments, in an embodiment, after configuring, by the terminal device, the master RLC entity in a master cell group MCG, the method further includes:
the terminal equipment executes measurement according to the measurement configuration configured by the auxiliary base station; and the terminal equipment generates a measurement report after executing measurement, carries the measurement report in a Radio Resource Control (RRC) signaling sent to a main base station and sends the RRC signaling to the main base station. The above operation may facilitate the network device side to continue to maintain the SCG, for example, when the primary secondary cell (SCell) signal is not good, the SCG may be released in time, or a Secondary Node (SN) handover may be performed.
In one embodiment, the measurement configuration is an intra-frequency measurement configuration or an inter-frequency measurement configuration. When the measurement configuration is the same-frequency measurement configuration, the SCG is convenient to maintain on the network equipment side, and the measurement frequency of the terminal equipment is simplified, so that the power consumption of the terminal equipment can be reduced.
Referring to fig. 8, a fifth embodiment of the present application further provides a method for deactivating and activating a secondary cell group, where the method is performed on a network device side. The method comprises the following steps:
step S100: the network equipment sends a first message to the terminal equipment, wherein the first message is used for indicating the SCG deactivation of the secondary cell group.
Step S200: after the network device sends the first message to the terminal device, the network device defaults the terminal device to configure the main Radio Link Control (RLC) entity in a Master Cell Group (MCG) under the condition that the main RLC entity of a separated Data Radio Bearer (DRB) is initially configured in the SCG.
Referring to fig. 9, a sixth embodiment of the present application further provides a method for deactivating and activating a secondary cell group, where the method is performed on a network device side. The method includes steps S100 to S400, where S100 and S200 are the same as the fifth embodiment except that it further includes:
step S300: and the network equipment sends a second message to the terminal equipment, wherein the second message is used for indicating the activation of the SCG.
Step S400: and after the network equipment sends a second message to the terminal equipment, the network equipment defaults the terminal equipment to configure the main RLC entity as initial configuration.
It is understood that the network device may be a primary base station or a secondary base station.
That is, after the SCG is deactivated or activated, the terminal device and the network device agree to change the location of the main RLC entity. That is, the terminal device receives the message for deactivating the SCG, and after the SCG is deactivated, the network device defaults that the terminal device configures the master RLC entity into the MCG. That is, the network device has defined therein: after sending out the message indicating the SCG deactivation, the main RLC entity of the default terminal equipment is configured into the MCG. After sending out the message indicating SCG activation, the main RLC entity of the default terminal device restores the initial setting. Therefore, once the terminal device performs an operation of changing the primary RLC entity, the terminal device does not need to send a message of changing the primary RLC entity to the network device, and the network device can also know that the primary RLC entity has changed.
In the same way, after the terminal device receives the message of reactivating the SCG and reactivates the SCG, the network device defaults the terminal device to reconfigure the main RLC entity into the SCG, that is, to restore the initial configuration.
In addition, the terminal device and the network device agree on the selection mode of the main RLC entity, and the agreed mode is the same as above. That is, defined in the network device are: after the SCG is deactivated, the fallback RLC entity of the MCG serves as the master RLC entity, and once the terminal device performs an operation of using the fallback RLC entity of the MCG as the master RLC entity, the network device may also know that the master RLC entity is changed to the fallback RLC entity of the MCG without sending a message for changing the master RLC entity to the network device.
Or the following are defined in the network device: after the SCG is deactivated, the corresponding Component Carrier (CC) RLC entity with the best signal is used as the main RLC entity. Or the following are defined in the network device: and after the SCG is deactivated, the corresponding RLC entity with the highest CC transmission success rate is used as a main RLC entity. Or the following are defined in the network device: after the SCG is deactivated, the RLC entity with the largest or smallest Logical Channel Identifier (LCID) is used as the primary RLC entity. In the same way, once the terminal device performs the operation of changing the master RLC entity, the network device can also know that the master RLC entity is changed to the fallback RLC entity of the MCG without sending a message for changing the master RLC entity to the network device.
Referring to fig. 10, an embodiment of the present invention further provides a communication apparatus, which includes a receiving unit 10 and a configuring unit 20. Wherein the receiving unit 10 is configured to receive a first message sent from the network device, where the first message is used to indicate that the secondary cell group SCG is deactivated. The configuration unit 20 is configured to configure the primary radio link control, RLC, entity of the detached data radio bearer, DRB, in a primary cell group, MCG, in case the primary RLC entity is initially configured in the SCG, after receiving the first message.
In one embodiment, the configuration unit 20 is further configured to configure the primary RLC entity as an initial configuration after receiving a second message sent by the network device, where the second message is used to indicate that the SCG is activated.
