The first embodiment,
The embodiment of the invention provides a method for deactivating a secondary cell by terminal equipment, which comprises the following steps:
and when the data transmitted on the first radio bearer reaches the maximum retransmission times on the first RLC entity, the terminal equipment deactivates the first auxiliary cell.
Specifically, as shown in fig. 1, the method provided in this embodiment includes the following steps:
step 101: and when the data transmitted on the first radio bearer reaches the maximum retransmission times on the first RLC entity, the terminal equipment deactivates the first auxiliary cell.
Step 102: and the terminal equipment reports the RLF message.
Here, the terminal device may be a terminal device in a mobile communication system, such as a smart terminal, a mobile phone, and the like.
For a radio bearer (DRB or SRB) using CA architecture for PDCP replication, its associated RLC entity triggers SCell-RLF, and the UE deactivates all activated SCells mapped to the RLC entity.
The first auxiliary cell is an auxiliary cell which has a mapping relation with a first RLC entity; wherein the mapping relationship is a secondary cell configured in a logical channel carrying the first RLC entity data and in an active state.
It should be understood that, in this embodiment, the first secondary cell may be one first secondary cell, or may be multiple first secondary cells, and the specific number is not limited in this embodiment.
And the auxiliary cell or the auxiliary cell group which has the mapping relation with the first RLC entity is the auxiliary cell or the auxiliary cell group which is configured in the first logic channel for bearing the RLC entity data.
Configuring a first basic parameter set in a corresponding logical channel of a first RLC entity, and configuring the first basic parameter set by the first secondary cell;
the method further comprises the following steps: and if the second auxiliary cell simultaneously configures the first basic parameter set, deactivating the second auxiliary cell.
Wherein the base parameter set may be represented by a subcarrier spacing.
The first RLC entities are in one-to-one correspondence with the first logical channels. It should also be understood that the first radio bearer and the first RLC entity are also in a corresponding relationship with each other.
The first radio bearer is a Signaling Radio Bearer (SRB) or a Data Radio Bearer (DRB).
The first radio bearer is:
a radio bearer configured with the data copy transmission function, or a radio bearer not configured with the data copy transmission function.
The method further comprises the following steps: when the first radio bearer is a radio bearer configured with a data copy transmission function, the data copy transmission is in an activated state or a deactivated state.
The first RLC entity is an Acknowledged Mode (AM) RLC entity, and data carrying a logical channel of the first RLC entity is transmitted only on the first secondary cell.
The present embodiment may be directed to a carrier aggregation CA architecture, and one form of the CA architecture may refer to fig. 2, where each RLC entity corresponds to one radio carrier. Based on the architecture provided in fig. 2, a logical channel corresponding to an RLC entity may be configured with one or a group of cells (groups), and the cells (groups) configured by two logical channels under CA duplicate are different, so that duplicate PDCP PDUs are transmitted on different carriers, and it may be further defined that p-leg is a transmission path corresponding to a primary RLC entity (e.g., RLC entity a in the figure) and s-leg corresponds to a transmission path corresponding to a secondary RLC entity (e.g., RLC entity b in the figure). Wherein p-leg means that when CA duplexing is deactivated, PDCP defaults to using leg, such as: both p-leg and s-leg belong to a non-primary cell or a non-primary cell group; p-leg corresponds to PCell/PSCell, and s-leg does not correspond to PCell; p-leg does not belong to Pcell/PScell, s-leg belongs to PCcell/PScell.
The terminal equipment suspends the data transmission of the first RLC entity, and the method comprises the following steps:
suspending data transmission of the first RLC entity after re-establishing the first RLC entity.
Wherein the suspending of data transmission of the first RLC entity comprises: suspending data transmission of a PDCP entity associated with the first RLC entity. In conjunction with the architecture described in fig. 2, it can be seen that the RLC entity and the PDCP entity have a data transmission relationship with each other, and therefore, suspending data transmission of the first RLC entity may include suspending data transmission between the first RLC entity and the PDCP entity. That is, the terminal device deactivates all cells in an active state that have a mapping relationship with the first RLC entity or the second RLC entity, where the mapping relationship refers to one or a group of cells of a logical channel configured by the RRC and corresponding to the RLC entity. Data of the logical channel can only be transmitted on one or a group of SCells of the configuration.
The RLC entity may be a primary RLC corresponding to the CA architecture PDCP duplicate radio bearer, or a secondary RLC: the primary RLC is the RLC to which the PDCP delivers new data after the duplicate deactivation, and is the primary RLC; the secondary RLC means that after the duplicate deactivation, the PDCP stops delivering new data to the RLC, which is the secondary RLC.
In addition, the suspending data transmission of the first RLC entity may further include: and deactivating the first secondary cell corresponding to the first RLC entity.
In addition, when the suspending of the data transmission of the first RLC entity, the method further includes:
and if the first auxiliary cell is deactivated, so that the second RLC entity has no available auxiliary cell group, stopping data transmission by the second RLC entity.
If the first auxiliary cell is deactivated, so that the second RLC entity does not have an available auxiliary cell group, the second RLC entity stops data transmission; wherein the stopping of the data transmission by the second RLC entity comprises reestablishing before stopping the data transmission. For example, the first RLC entity corresponds to the secondary cell group {123}, the second RLC entity corresponds to {23}, and since the first RLC entity triggers the SCell-RLF, resulting in 123 deactivation, it means that the second RLC entity has no available secondary cells, and the second RLC may suspend data transmission.
Or, if the first secondary cell is deactivated, so that the second RLC entity has no available secondary cell group, and the second RLC entity is configured with other secondary cells or secondary cell groups in a deactivated state, activating the secondary cells or secondary cell groups. For example, the first RLC entity corresponds to the secondary cell group {123}, the second RLC entity corresponds to {234}, and since the first RLC entity triggers the SCell-RLF, 123 is deactivated, and 4 is in a deactivated state, the terminal may activate 4.
The method further comprises at least one of:
the terminal equipment reports a Radio Link Failure (RLF) message which contains an Identifier (ID) of a deactivated first auxiliary cell;
and the terminal equipment reports the RLF message containing the ID of the activated first auxiliary cell.
The first RLC entity or the second RLC entity is a main RLC or a secondary RLC entity of a PDCP copy function radio bearer in a carrier aggregation architecture. The RLC entity may be a primary RLC corresponding to the CA architecture PDCP duplicate radio bearer, or a secondary RLC: the primary RLC is the RLC to which the PDCP delivers new data after the duplicate deactivation, and is the primary RLC; the secondary RLC means that after the duplicate deactivation, the PDCP stops delivering new data to the RLC, which is the secondary RLC.
The data transmitted on the first radio bearer reaches the maximum retransmission times on the first RLC entity, including: and when the retransmission counter corresponding to the RLC SDU of the first RLC entity reaches a configured threshold value, determining that the maximum retransmission times of the data transmitted on the first radio bearer on the first RLC entity are reached.
That is to say, the triggering of the SCell-RLF is when a retransmission counter RETX _ COUNT corresponding to a certain RLC SDU of the RLC entity reaches a configured threshold maxRetxThreshold.
When the first secondary cell in the activated state and having the mapping relation with the first RLC entity is deactivated, if the first secondary cell in the inactivated state exists in the first secondary cell corresponding to the first RLC entity, activating the secondary cell or the secondary cell group in the inactivated state. And the UE deactivates all SCells in the activated state that have a mapping relationship with the RLC entity, and optionally, if there are SCells in the inactivated state in the SCell configured with the logical channel corresponding to the RLC entity, the UE may activate the SCells.
The method further comprises the following steps: and for the first secondary cell in the activated state, which has the mapping relation with the first RLC entity associated with the first radio bearer, deactivating the data copying and transmitting function of the first radio bearer. The UE deactivates all cells in the activated state that have a mapping relationship with the RLC entity, and optionally, the UE may deactivate a data copy transmission function of the corresponding bearer.
Therefore, by adopting the scheme, whether the terminal equipment deactivates the first secondary cell with the mapping relation of the first RLC entity can be controlled based on the maximum retransmission times. Therefore, for the RLC entity, if all the cell groups configured by the corresponding logical channel are secondary cells, the RRC reconfiguration is not triggered, and only the event that the retransmission reaches the maximum number of times needs to be reported, so that the influence of the reconfiguration on the terminal equipment is reduced.
Example II,
An embodiment of the present invention provides a terminal device, as shown in fig. 3, including:
the processing unit 31 deactivates the first secondary cell when the data transmitted on the first radio bearer reaches the maximum retransmission times on the first RLC entity.
The communication unit 32 reports the radio link failure RLF message.
Here, the terminal device may be a terminal device in a mobile communication system, such as a smart terminal, a mobile phone, and the like.
For a radio bearer (DRB or SRB) using CA architecture for PDCP replication, its associated RLC entity triggers SCell-RLF, and the UE deactivates all activated SCells mapped to the RLC entity.
The first auxiliary cell is an auxiliary cell which has a mapping relation with a first RLC entity; wherein the mapping relationship is a secondary cell configured in a logical channel carrying the first RLC entity data and in an active state. It should be understood that, in this embodiment, the first secondary cell may be one first secondary cell, or may be multiple first secondary cells, and the specific number is not limited in this embodiment.
And the auxiliary cell or the auxiliary cell group which has the mapping relation with the first RLC entity is the auxiliary cell or the auxiliary cell group which is configured in the first logic channel for bearing the RLC entity data.
The secondary cell or the secondary cell group with the mapping relation with the first RLC entity is one or more basic parameter sets configured in a first logic channel for bearing RLC entity data;
configuring a first basic parameter set in a corresponding logical channel of a first RLC entity, and configuring the first basic parameter set by the first secondary cell;
if there is a second secondary cell and the first basic parameter set is configured, the processing unit 31 deactivates the second secondary cell.
Wherein the base parameter set may be represented by a subcarrier spacing.
The first RLC entities are in one-to-one correspondence with the first logical channels. It should also be understood that the first radio bearer and the first RLC entity are also in a corresponding relationship with each other.
The first radio bearer is a Signaling Radio Bearer (SRB) or a Data Radio Bearer (DRB).
The first radio bearer is:
a radio bearer configured with the data copy transmission function, or a radio bearer not configured with the data copy transmission function.
The method further comprises the following steps: when the first radio bearer is a radio bearer configured with a data copy transmission function, the data copy transmission is in an activated state or a deactivated state.
The first RLC entity is an Acknowledged Mode (AM) RLC entity, and data carrying a logical channel of the first RLC entity is transmitted only on the first secondary cell.
The present embodiment may be directed to a carrier aggregation CA architecture, and one form of the CA architecture may refer to fig. 2, where each RLC entity corresponds to one radio carrier. Based on the architecture provided in fig. 2, a logical channel corresponding to an RLC entity may be configured with one or a group of cells (groups), and the cells (groups) configured by two logical channels under CA duplicate are different, so that duplicate PDCP PDUs are transmitted on different carriers, and it may be further defined that p-leg is a transmission path corresponding to a primary RLC entity (e.g., RLC entity a in the figure) and s-leg corresponds to a transmission path corresponding to a secondary RLC entity (e.g., RLC entity b in the figure). Wherein p-leg means that when CA duplexing is deactivated, PDCP defaults to using leg, such as: both p-leg and s-leg belong to a non-primary cell or a non-primary cell group; p-leg corresponds to PCell/PSCell, and s-leg does not correspond to PCell; p-leg does not belong to Pcell/PScell, s-leg belongs to PCcell/PScell.
The processing unit 31 suspends data transmission of the first RLC entity after reconstructing the first RLC entity.
Wherein the suspending of data transmission of the first RLC entity comprises: suspending data transmission of a PDCP entity associated with the first RLC entity. In conjunction with the architecture described in fig. 2, it can be seen that the RLC entity and the PDCP entity have a data transmission relationship with each other, and therefore, suspending data transmission of the first RLC entity may include suspending data transmission between the first RLC entity and the PDCP entity. That is, the terminal device deactivates all cells in an active state that have a mapping relationship with the first RLC entity or the second RLC entity, where the mapping relationship refers to one or a group of cells of a logical channel configured by the RRC and corresponding to the RLC entity. Data of the logical channel can only be transmitted on one or a group of SCells of the configuration.
The RLC entity may be a primary RLC corresponding to the CA architecture PDCP duplicate radio bearer, or a secondary RLC: the primary RLC is the RLC to which the PDCP delivers new data after the duplicate deactivation, and is the primary RLC; the secondary RLC means that after the duplicate deactivation, the PDCP stops delivering new data to the RLC, which is the secondary RLC.
In addition, the suspending data transmission of the first RLC entity may further include: and deactivating the secondary cell or the secondary cell group corresponding to the first RLC entity.
In addition, the processing unit 31 stops data transmission by the second RLC entity if the first secondary cell is deactivated, so that the second RLC entity has no available secondary cell group.
If the first auxiliary cell is deactivated, so that the second RLC entity does not have an available auxiliary cell group, the second RLC entity stops data transmission; wherein the stopping of the data transmission by the second RLC entity comprises reestablishing before stopping the data transmission. For example, the first RLC entity corresponds to the secondary cell group {123}, the second RLC entity corresponds to {23}, and since the first RLC entity triggers the SCell-RLF, resulting in 123 deactivation, it means that the second RLC entity has no available secondary cells, and the second RLC may suspend data transmission.
Or, if the first secondary cell is deactivated, so that the second RLC entity has no available secondary cell group, and the second RLC entity is configured with other secondary cells or secondary cell groups in a deactivated state, activating the secondary cells or secondary cell groups. For example, the first RLC entity corresponds to the secondary cell group {123}, the second RLC entity corresponds to {234}, and since the first RLC entity triggers the SCell-RLF, 123 is deactivated, and 4 is in a deactivated state, the terminal may activate 4.
The processing unit 31 further includes at least one of:
the terminal equipment reports a Radio Link Failure (RLF) message which contains a deactivated first auxiliary cell (ID);
and the terminal equipment reports the RLF message containing the ID of the activated first auxiliary cell.
The first RLC entity or the second RLC entity is a main RLC or a secondary RLC entity of a PDCP copy function radio bearer in a carrier aggregation architecture. The RLC entity may be a primary RLC corresponding to the CA architecture PDCP duplicate radio bearer, or a secondary RLC: the primary RLC is the RLC to which the PDCP delivers new data after the duplicate deactivation, and is the primary RLC; the secondary RLC means that after the duplicate deactivation, the PDCP stops delivering new data to the RLC, which is the secondary RLC.
The processing unit 31 determines that the maximum retransmission times of the data transmitted on the first radio bearer on the first RLC entity is reached when the retransmission counter corresponding to the RLC SDU of the first RLC entity reaches the configured threshold.
That is to say, the triggering of the SCell-RLF is when a retransmission counter RETX _ COUNT corresponding to a certain RLC SDU of the RLC entity reaches a configured threshold maxRetxThreshold.
When the first secondary cell in the activated state having the mapping relationship with the first RLC entity is deactivated, if the secondary cell or the secondary cell group in the inactivated state exists in the secondary cell or the secondary cell group corresponding to the first RLC entity, the processing unit 31 activates the secondary cell or the secondary cell group in the inactivated state. And the UE deactivates all SCells in the activated state that have a mapping relationship with the RLC entity, and optionally, if there are SCells in the inactivated state in the SCell configured with the logical channel corresponding to the RLC entity, the UE may activate the SCells.
The processing unit 31 deactivates a data copy transmission function of the first radio bearer for the first secondary cell in an active state having a mapping relationship with the RLC entity associated with the first radio bearer. The UE deactivates all cells in the activated state that have a mapping relationship with the RLC entity, and optionally, the UE may deactivate a data copy transmission function of the corresponding bearer.
Therefore, by adopting the scheme, whether the terminal equipment deactivates the secondary cell or the secondary cell group with the mapping relation of the first RLC entity can be controlled based on the maximum retransmission times. Therefore, for the RLC entity, if all the cell groups configured by the corresponding logical channel are secondary cells, the RRC reconfiguration is not triggered, and only the event that the retransmission reaches the maximum number of times needs to be reported, so that the influence of the reconfiguration on the terminal equipment is reduced.
