Description

Cell configuration method, base station and terminal device

Technical field

The present application relates to the field of communications, and in particular, to a cell configuration method, a base station, and a terminal device.

Background technique

In order to meet the requirements of the Long Term Evolution-Advanced (LTE-A) downlink peak speed of 1 Gbps and the uplink peak speed of 500 Mbps, it is necessary to provide a transmission bandwidth of up to 100 MHz, but due to the scarcity of the continuous spectrum of the transmission bandwidth LTE-A proposes a carrier aggregation (CA) solution. CA is a combination of two or more component carriers (CCs) to support a larger transmission bandwidth (up to 100 MHz). In fact, each CC corresponds to an independent cell, and the maximum bandwidth of each CC is 20 MHz. After the CA is configured, the user equipment (User Equipment, UE) can simultaneously perform data transmission and reception with multiple cells. Therefore, the throughput of the UE can be improved.

With the deployment of heterogeneous networks, small cell deployments have become more common. In LTE Rel-13, the CA operation performed by the UE is extended to 32 carriers, and the number of CCs is greatly increased. A cell corresponding to one carrier may serve as a primary cell (PCell) for the UE, and a cell corresponding to the other 31 carriers may serve as a secondary cell (SCell) for the UE. In the CA scenario, the PCell serving as the mobility anchor of the UE can reduce the handover operation of the UE, and the SCell is densely deployed on different frequencies for improving the user plane capacity.

In the LTE CA, after the UE enters the Radio Resource Control (RRC) connection state, the base station sends an RRC connection reconfiguration message carrying configuration information of one or more SCells configured for the UE. The status of the configured SCell is deactivated by default. Before using the SCell for data transmission, the base station needs to send a Medium Access Control (MAC) cell (Control Element, CE) to activate the configured SCell. UE data transmission. However, the coverage of the SCell is small. As the UE moves, the quality of the SCell of the UE changes rapidly. Therefore, the SCell of the UE will be frequently configured or configured, or activated frequently after the configuration. Deactivation, signaling overhead. Moreover, when the deployment of the small cell becomes more dense, and the number of carriers that the UE performs CA operations exceeds 5 (up to possibly 32), the signaling overhead of the RRC connection reconfiguration message used by the base station to configure the SCell is also relatively high. The number of bits occupied by the MAC CE used to activate or deactivate the SCell is also relatively large, for example, it can be 32 bits, which also makes the signaling overhead large.

Summary of the invention

The embodiment of the present application provides a cell configuration method, a base station, and a terminal device, which can reduce the signaling overhead of the secondary cell configuration and activation of the terminal device.

A first aspect of the present invention provides a cell configuration method, including: a base station sends a first configuration message to a terminal device, where the first configuration message includes configuration information of at least one cell, and configuration information of each cell includes an index of the cell or a cell to which the cell belongs. An index of a group of a group of cells; the base station sends a second configuration message to the terminal device, where the second configuration message includes an index of N cells or an index of N groups of cells, where N is a positive integer greater than 1, and the second configuration message is used. The configuration information of the cell corresponding to the index of the N cells or the index of the N groups of cells in the at least one cell is configured to be the configuration information of the secondary cell of the terminal device. In this way, the configuration of the cell of the terminal device is not frequently configured due to the movement of the terminal device, and the configuration of the cell of the terminal device can be semi-statically changed in a long period of time, which reduces the transmission frequency of the first configuration message, so that the signal Reduce the overhead. Moreover, the index of the cell or the index of the group in the second configuration message does not carry the specific configuration information of the cell, so that the bit size occupied by the second configuration message is greatly reduced, and the signaling overhead is further reduced.

In a possible design, the first configuration message is a system message or a radio resource control RRC message, and the second configuration message is an RRC message, or a media intervention control cell MAC CE, or a physical downlink control channel PDCCH signaling.

The index of the group that carries the group of cells in the first configuration message and the index of each cell in each group may carry only the group to be configured as the secondary cell when sending the second configuration message, with respect to the index that carries only the cell.

In this way, once the configuration information of the cell is updated, the third configuration message or the second configuration message may be implemented. The fourth configuration message also has the function of updating the configuration and activating the secondary cell, and does not need to send the activation message to activate the secondary cell, which can reduce the signaling overhead.

The basic principle of the application is: the base station provides configuration information of the at least one cell to the terminal device by using the first configuration message, where the configuration information of the cell includes an index of the cell or an index of a group of the group of the cell where the cell is located, and the configuration of the terminal device stores the cell. information. The base station provides the index of the index or the group of the cell to be configured as the secondary cell to the terminal device by using the second configuration message, where the specific configuration information of the cell is not carried in the second configuration message, and the terminal device may be based on the index of the cell or the index of the group. The configuration information of the secondary cell is obtained in the configuration information of the cell. In this way, the configuration of the cell of the terminal device is not frequently configured due to the movement of the terminal device, and the configuration of the cell of the terminal device can be semi-statically changed in a long period of time, which reduces the transmission frequency of the first configuration message, so that the signal Reduce the overhead. Moreover, the index of the cell or the index of the group in the second configuration message does not carry the specific configuration information of the cell, so that the bit size occupied by the second configuration message is greatly reduced, and the signaling overhead is further reduced.

Embodiments of the present application will be described below.

The embodiment of the present application provides a cell configuration method, where a cell in this embodiment can be understood as a small cell, as shown in FIG. 4, including:

401. The base station sends a first configuration message to the user equipment terminal device, where the first configuration message includes configuration information of the at least one cell, and the configuration information of each cell includes an index of the cell or an index of a group of the group of cells to which the cell belongs.

Illustratively, it can be assumed that the configuration update of the cell is infrequent, that is, semi-statically changed over a longer period of time. Therefore, the base station may send the configuration information of the multiple cells to the terminal device through the first configuration message, and then instruct the terminal device to be configured as the cell of the SCell.

Optionally, the first configuration message may be a system message or a radio resource control RRC message. For example, if the base station determines that the terminal device is in the idle state, the first configuration message may be a system message; if the base station determines that the UE is in the connected state, the first configuration message may be a dedicated RRC message.

In a possible design, if the configuration information of each cell includes an index of the cell, the configuration information of each cell further includes at least one of a physical cell identifier PCI, a carrier frequency, and a radio resource configuration of the cell. The radio resource configuration may include a physical channel, configuration information when uplink and downlink signals are transmitted, and the like.

In one example, the configuration information of the at least one cell includes public information of the at least one cell and information specific to each cell in the at least one cell, where the public information is carried in a common information field of the first configuration message, and the number of the public information fields is less than at least The number of a cell. That is to say, the public information in the configuration information of at least one cell may be repeated multiple times, but may be less than the number of at least one cell. This saves the signaling overhead of the first configuration message. In one possible design, the number of public information fields is one. That is to say, the public information of the configuration information of the at least one cell appears once in the first configuration message, that is, the public information of each cell can be uniformly notified, and each cell-specific information can be separately notified, which can further save the first The signaling overhead of a configuration message. The public information here appears once as a public information field. For example, if the public information of each cell occupies 5 bits, and the first configuration message carries configuration information of 5 cells, the public information in the configuration information of the 5 cells occupies 25 bits, but if the public information is in a specific bit of the first configuration message, The location only occurs once, which saves 20 bits of signaling overhead. As shown in Table 1, Table 1 shows configuration information of multiple cells carried in the first configuration message.

Table 1 Contents of the first configuration message

As can be seen from Table 1, the first configuration message includes common information of a plurality of cells, such as cell 1 (Cell 1), cell 2 (Cell 2), and cell 3 (Cell 3), and information specific to each cell. The information specific to each cell may include, for example, a cell index (Cell index), a PCI, a carrier frequency (Frequency), and a cell-specific radio configuration of the cell.

The parameters included in the above public information can be as shown in Table 2.

In another possible design, if the configuration information of each cell includes an index of a group of a group of cells to which the cell belongs, the configuration information of each group of cells includes an index of a group of the group of cells, and the group of cells At least one of PCI, carrier frequency, and radio resource configuration of each cell. That is to say, the cells in the first configuration message can be grouped, and each group of cells corresponds to an index of one group. The base of the packet may be determined by the base station based on cell deployment or location, for example, grouping multiple cells with a relatively close cell coverage into one group.

Similarly, if there is public information in the configuration information of any group of cells, in order to save signaling overhead, the public information in the configuration information of the group of cells is carried in the common information field of the first configuration message.

402. The terminal device receives a first configuration message sent by the base station.

After receiving the first configuration message sent by the base station, the terminal device may store configuration information of the cell in the first configuration message.

As a result, the coverage of the SCell is small, and the quality of the SCell of the terminal device changes rapidly as the terminal device moves. When the SCell needs to be configured/deconfigured frequently, the present application can carry multiple cells by using the first configuration message. The configuration information is sent to the terminal device, so that the terminal device stores configuration information of multiple cells at a time, which can reduce the frequency of configuring/deconfiguring the cell for sending the configuration message.

403. The base station sends a second configuration message to the terminal device, where the second configuration message includes an index of the N cells or an index of the N groups of cells, where N is a positive integer greater than 1, and the second configuration message is used to indicate that the terminal device is to perform at least one cell. The configuration information of the cell corresponding to the index of the N cells or the index of the N groups of cells is configured as the configuration information of the secondary cell of the terminal device.

After the terminal device enters the RRC connected state, the base station may configure the SCell cell to the terminal device if it determines that the terminal device requires additional radio resources.

In one example, the second configuration message may be an RRC message, or a media intervention control cell MAC CE, or a physical downlink control channel PDCCH signaling.

Optionally, the second configuration message may further include a specific radio resource configuration of the cell configured as the SCell, where the specific radio resource configuration indicates that the terminal device updates a certain configuration information of a certain cell, and then configures the terminal device as a terminal device. SCell.

In this way, the base station can carry the index of the cell configured as the SCell and the optional specific radio resource configuration by using the second configuration message, so that the second configuration message can carry the Cellindex configured as the SCell or the group of the Cell configured as the SCell. The index does not need to carry the configuration other than the index of the cell configured as SCell. The information can be used to reduce the bit size of the configuration message of the SCell, that is, the signaling overhead is reduced. It is not required to carry all the configuration information of each cell for the terminal device each time the SCell is configured.

404. The terminal device receives a second configuration message sent by the base station.

In a possible design, as shown in FIG. 5, the first RRC message is received when the terminal device is in the connected state, and the first RRC message carries configuration information of at least one cell, and then the base station sends the second RRC to the terminal device. a message, the second RRC message includes an index of the N cells or an index of the N groups of cells, and indicates that the terminal device configures the configuration information of the N cells or the information of the cells corresponding to the N groups of cells as the configuration of the SCell of the terminal device. After receiving the second RRC message, the terminal device queries the configuration information of the cell, and configures the configuration information of the cell corresponding to the index of the N cells or the index of the N groups of cells as the configuration information of the SCell of the terminal device. Then, the base station can send a MAC CE to the terminal device, and the MAC CE is used to activate the SCell, and the cell as the SCell can be used for the terminal device to perform data communication.

In another possible design, as shown in FIG. 6, the first RRC message is received when the terminal device is in the connected state, and the first RRC message carries configuration information of at least one cell, and then the base station sends the third information to the terminal device. RRC message, the third RRC message includes an index of the N cells or an index of the N groups of cells, and indicates that the terminal device configures the configuration information of the cell of the N cells or the cell of the N group of cells as the SCell of the terminal device. After the third RRC message is received, the terminal device queries the configuration information of the cell, and configures the configuration information of the cell corresponding to the index of the N cells or the index of the N groups of cells as the configuration information of the SCell of the terminal device. The third RRC message may also be used to activate the SCell, that is, the second configuration message is further used to instruct the terminal device to activate the secondary cell of the terminal device. In this way, after receiving the third RRC message and configuring the SCell, the terminal device can directly activate the configured SCell, and the base station does not need to send a message for activating the SCell to the terminal device to save signaling overhead.

In another possible design, as shown in FIG. 7, it is assumed that the terminal device is in the connected state, and receives the first RRC message, where the first RRC message carries configuration information of at least one cell, and then the base station may send the MAC CE to the terminal device. Or the PDCCH, where the MAC CE or the PDCCH includes an index of the N cells or an index of the N groups of cells, and indicates that the terminal device configures the configuration information of the N cells or the cells of the N groups of cells as the SCell of the terminal device. The configuration information is that, when receiving the MAC CE or the PDCCH, the terminal device queries the configuration information of the cell, and configures the configuration information of the cell corresponding to the index of the N cells or the index of the N groups of cells as the configuration information of the SCell of the terminal device, and activates After the SCell is configured, the activated SCell can be used for data communication of the terminal device. The MAC CE or the PDCCH carries the index to be configured as the SCell. The MAC CE belongs to the L2 signaling, and the PDCCH belongs to the L1 signaling, which can improve the sending speed of the configuration message. Make the cost even smaller.

It should be noted that the embodiment of the present application can also be applied to LTE, and can also be applied to the LTE-New Air Interface (New Radi0, NR) dual connection. In LTE-NR, LTE can be deployed as a primary base station for macros, and NRs can be deployed in small cells, especially at high frequencies.

It should be noted that the index of the group or group of cells is carried in the second configuration message, and the index of the multiple cells is not required to be carried, so that the signaling overhead of the second configuration message can be further reduced by means of the packet. .

If the configuration information of the cell changes, the base station may further notify the terminal device to update the configuration information of the cell. Therefore, the method embodiment may further include:

405. The base station sends a third configuration message to the terminal device, where the third configuration message is a system message or an RRC message. The third configuration message includes configuration information of the updated cell.

For example, the configuration information of the updated cell may include information to be updated after the configuration information of the cell that the terminal device has stored, and may include configuration information of the newly added cell of the base station, or an index including configuration information of the cell to be deleted by the base station. Wait.

Or, when the base station needs to update the cell configuration information saved by the terminal device, the base station may send a fourth configuration message to the terminal device, where the fourth configuration message is an RRC message, or a MAC CE, or PDCCH signaling, and the fourth configuration message includes the updated cell. And the fourth configuration message is used to instruct the terminal device to replace the configuration information of the last configured secondary cell according to the updated cell configuration information. That is to say, the fourth configuration message is not only used to indicate that the terminal device updates the configuration information of the saved cell, and the configuration information of the updated cell is also configured as the configuration information of the SCell of the terminal device.

406. The terminal device receives a third configuration message sent by the base station.

When the terminal device receives the third configuration message, the terminal device may update the configuration information of the locally stored cell according to the information carried in the third configuration message.

When the terminal device receives the fourth configuration message, the terminal device may update the configuration information of the locally stored cell according to the information carried in the fourth configuration message, and the terminal device replaces the configuration information of the updated cell with the stored SCell. Configuration information.

In steps 403 to 404, if the second configuration message is used to set the configuration information of the cell to the configuration information of the SCell, and the capability of the SCell is not combined, for example, when the second configuration message is the first RRC message, The MAC CE is used to activate/deactivate the SCell. The embodiment of the present application can also reduce the overhead of activating the MAC CE signaling of the SCell. In this case, after step 404, the method may further include:

407. The base station sends a fifth configuration message to the terminal device, where the fifth configuration message is an RRC message, and the fifth configuration message includes packet information of the secondary cell of the terminal device, where the group information includes an identifier of a group of each group of secondary cells and each group of secondary cells. The index of the included cell.

That is, after the terminal device configures the configuration information of the cell as the configuration information of the SCell, the cell configured as the SCell may be further divided into one or more groups, each group of SCells includes at least one SCell, and each group of SCells is The identifier of a group is configured, and the group information of the SCell group corresponding to the identifier of each group includes an index of at least one SCell included in the SCell group.

For example, a plurality of SCells configured by the base station are grouped to include SCell Group1, SCell Group2, ..., SCell Group m, where SCell Group1 may include multiple SCells indexed as SCell1-1, SCell1-2, ..., SCell1-n, and the like. The SCell Group 2 may include multiple SCells indexed as SCell2-1, SCell2-2, ..., SCell2-n, and the SCell Group m may include multiple indexes such as SCell1-1, SCell1-2, ..., SCell1-n, and the like. SCell.

How to determine the SCell's packet can depend on the implementation of the base station, such as the base station based on cell deployment, location or measurement.

408. The terminal device receives a fifth configuration message sent by the base station.

The terminal device may learn, according to the group information in the fifth configuration message, at least one SCell corresponding to each group of SCells.

409. The base station sends a first MAC CE or a second MAC CE to the terminal device, where the first MAC CE includes bit information corresponding to the identifier of the group of the secondary cell, and the second MAC CE includes the identifier of the group of the at least one group of the secondary cells. to Bit information corresponding to the identifier of a group of a group of secondary cells.

For example, the base station sends the first MAC CE to the terminal device, where the first MAC CE includes bit information corresponding to the identifier of the group of each group of SCells. For example, the SCell of the terminal device is divided into 8 groups, and each group of SCells is activated or deactivated by a bitmap. The bit information corresponding to the identifier of the group of the group of the secondary cells is a first bit value or a second bit value, where the first bit value is used to indicate that each secondary cell included in the group of secondary cells is activated, and the second bit value is used. Deactivated to indicate each secondary cell included in the group of secondary cells. For example, the first bit value is 1, and 1 indicates that the corresponding SCell group is activated, and the second bit value is 0, and 0 indicates that the corresponding SCell group is deactivated. It is assumed that the identifiers of the groups of the eight groups of SCells are G0, G1, G2, G3, G4, G5, G6, G7, and G8, and the partial signaling formats of the identifiers of the groups of SCells in the MAC CE are as shown in Table 3.

For example, the value of the bit corresponding to the identifier of each group of SCells in Table 1 is as shown in Table 2, indicating that the SCells included in the SCell group corresponding to G0, G2, and G5 are activated, and the SCell groups corresponding to G1, G3, G4, G6, and G7 are activated. The included SCell is deactivated. If the number of SCell groups to be divided is less than 8 groups, the reserved Rbit can be added in Table 4.

For example, the base station sends the second MAC CE to the terminal device, where the second MAC CE includes the identifier of the group of at least one group of SCells and the bit information corresponding to the identifiers of the groups of the at least one group of SCells. For example, Table 5 shows the partial signaling format in the MAC CE when a group of SCells is activated/deactivated, and Table 6 shows the partial signaling formats in the MAC CE when the two SCells are activated/deactivated.

In Table 5 and Table 6, R represents a reserved bit, and the bit corresponding to Ind indicates activation or deactivation. Similar to the above procedure, when the bit information corresponding to Ind is the first bit value 1, the Group ID indication corresponding to the activation of Ind may be indicated. In the SCell group, if the bit information corresponding to Ind is the second bit value of 0, the SCell group indicated by the Group ID corresponding to Ind may be deactivated.

410. The terminal device receives the first MAC CE or the second MAC CE sent by the base station, and activates or deactivates the secondary cell according to the first MAC CE or the second MAC CE.

That is, the terminal device may activate/deactivate the corresponding group of SCells or groups of SCells according to the first MAC CE or the second MAC CE. The index of each activated/deactivated SCell needs to be carried in the case of the SCell grouping. The embodiment of the present application may pass the first MAC CE or the second in the case of grouping the SCells. The MAC CE carries the identifier of the activated/deactivated SCell group, and does not need to carry the identifier of each SCell, which can reduce the number of bits occupied by the MAC CE and reduce the signaling overhead of the MAC CE.
