Description

Carrier aggregation method, device and system

The present invention relates to communications technologies, and in particular, to a carrier aggregation method, device, and system. BACKGROUND OF THE INVENTION With the rapid development of communication technologies, the number and throughput requirements of mobile terminal users are increasing. However, since the carrier resources of a single cell are limited, when there is no idle carrier resource available for the cell, the cell is under the cell. Users cannot achieve the peak throughput of user capabilities.

The 3rd Generation Partnership Project (3GPP) introduced Carrier Aggregation (CA) technology in the Release 10 phase to aggregate multiple consecutive or non-contiguous carriers into larger ones. The bandwidth is configured to meet the peak throughput requirement of a single user equipment (UE). The aggregated carrier consists of one primary carrier and one or more secondary carriers. According to the 3GPP protocol, the primary carrier needs to send service data and control messages. The secondary carrier may only transmit service data, and the control message on the secondary carrier may be sent on the primary carrier.

The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of a carrier aggregation method according to Embodiment 1 of the present invention. As shown in FIG. 1, the method includes:

Step 101: The first entity determines a secondary carrier cell of the CA. The first entity is used to control a primary carrier cell of the CA, where the primary carrier cell is a cell in a first duplex mode, and the secondary carrier cell is a In the cell of the two-duplex mode, the first duplex mode is different from the second duplex mode.

The first entity may be an Evolved Node B (eNB) for controlling the primary carrier cell, or a board for controlling the primary carrier cell in the eNB. Optionally, the first duplex mode may be a Frequency Dividing Duplex (FDD) mode, and the second duplex mode may be a Time Division Duplex (TDD) mode. Optionally, the first duplex mode may be a TDD mode, and the second duplex mode may be an FDD mode.

Optionally, the first entity determines a secondary carrier cell of the carrier aggregation CA, and the method includes: the first entity is in an operation support system (OSS) (Operation Support System, referred to as

0SS)) In the configured cell set, the secondary carrier cell of the CA is selected, and the cell set includes at least one cell of the second duplex mode. Optionally, the set of cells further includes at least one cell of the first duplex mode. For example, the cell identifier of each cell may be included in the cell set.

In a CA process, the CA may have one or more secondary carrier cells. Optionally, the 0SS may further configure a parameter such as a CA threshold, where the CA threshold is used by the first entity to determine when to start the CA.

Step 102: The first entity exchanges first data with the UE, and interacts with the UE by using the second data by the second entity. The second entity is used to control the secondary carrier cell of the CA.

The second entity may be an eNB that controls the secondary carrier cell, or a board that is used by the eNB to control the secondary carrier cell. When there are multiple secondary carrier cells, the multiple auxiliary carriers The wave cells may correspond to the same second entity, or may correspond to different second entities. The first entity exchanges data with the UE by using a second entity corresponding to each secondary carrier cell.

Optionally, the CA may be an uplink CA or a downlink CA. When the downlink CA is performed, the first entity divides the downlink data to be sent to the UE into the first data and the second data, and the first entity sends the second data to the second entity. And being sent by the second entity to the UE. When the uplink CA is performed, the UE divides the uplink data into the first data and the second data, and sends the first data directly to the first entity, and sends the second data to the second entity. And sending, by the second entity, the second data to the first entity, and then the first entity aggregates the first data and the second data and sends the first data to the upper layer.

It should be noted that, if there are N secondary carrier cells in a downlink CA, and N is a positive integer greater than 1, the first entity divides the downlink data to be sent to the UE into (N+1) copies. That is, the first data and the N second data; each of the second data corresponds to one secondary carrier cell, and is sent to the UE by using the secondary carrier corresponding to the secondary carrier cell. If there are N secondary carrier cells in an uplink CA, and N is a positive integer greater than 1, the UE divides the uplink data into (N+1) shares, that is, the first data and the N copies of the second data; The second data is corresponding to one secondary carrier cell, and is sent to the corresponding second entity by using the secondary carrier corresponding to the secondary carrier cell.

Optionally, when the first entity and the second entity are different eNBs, the first entity and the second entity may interact through the X2 interface. Optionally, the first entity and the second entity may be different boards in the same eNB, and correspondingly, the interaction between the first entity and the second entity may be implemented by using an internal interface of the eNB.

In an alternative embodiment of the invention, there is no need to modify the air interface protocol. Correspondingly, before step 102, the method may further include:

For example, the first entity may search for a pre-configured cell information table according to the cell identifier of the secondary carrier cell obtained from the set of cells, and determine a frequency range of the secondary carrier corresponding to the secondary carrier cell. Optionally, the first entity may also search a pre-configured cell information table, and determine the The overlapping frequency ranges are corresponding to the frequency points in the first duplex mode.

For example, when the first duplex mode is the FDD mode and the second duplex mode is the TDD mode, the frequency range corresponding to the secondary carrier overlaps with the frequency range of the first duplex mode, that is, the TDD mode. The frequency range corresponding to the secondary carrier overlaps with the frequency range of the FDD mode. For example, the overlapping frequency ranges are within a frequency range in which the first duplex mode and the second duplex mode overlap.

Table 1 shows the evolution of the Universal Mobile Telecommunications System (UMTS) defined by the 3GPP protocol. The operating frequency bands of the Evolved UMTS Terrestrial Radio Access (E-UTRA) are in the FDD mode and the TDD mode. Band table of overlapping frequency ranges.

Table 1

As shown in Table 1, the FDD mode operating band (Band) 2 has an uplink operating band of 1850 MHz_1910 MHz and a downlink operating band of 1930-1990 MHz, and has a overlapping downlink frequency range with the Band 36 of the TDD mode, and correspondingly, the FDD mode of Band2 The cell can be selected as the secondary carrier cell of the downlink CA that does not change the air interface protocol mode; the Band2 in the FDD mode and the Band35 in the TDD mode have overlapping uplink frequency ranges, so the cell of the Band2 in the FDD mode can also be selected as the air interface protocol. The secondary carrier cell of the uplink CA. Similarly, the Band41 of the TDD mode has an uplink frequency range and a downlink frequency range of 2496 MHz to 2690 MHz, wherein the 2500 MHz_2570 MHz overlaps with the uplink frequency range of the Band 7 of the FDD mode, and thus the cell of the 2500 MHz_2570 MHz band of the TDD mode can be selected as the embodiment of the present invention. The secondary carrier cell of the uplink CA, in the same way, the 2620MHz-2690MHz in the TDD mode overlaps with the downlink frequency range of the Band7 in the FDD mode, so the TDD mode The cell of the band 2620 MHz-2690 MHz may be selected as the secondary carrier cell of the downlink CA in the embodiment of the present invention.

According to the above analysis, the first entity determines that the frequency range of the secondary carrier corresponding to the secondary carrier cell may be within a frequency range overlapping in the downlink working frequency band of different duplex modes in Table 1, or is different from that in Table 1. The overlapping frequency ranges in the downlink operating band of the duplex mode overlap. For example, the first duplex mode is the FDD mode, the second duplex mode is the TDD mode, and the secondary carrier has a frequency range of 2620 MHz-2630 MHz, and the frequency range is in the downlink operating frequency range of the Band7 of the FDD mode, that is, the first The frequency range of a duplex mode overlaps, and the overlapping frequency range is 2620MHz-2630MHz. o For example, the first duplex mode is FDD mode, the second duplex mode is TDD mode, and the secondary carrier frequency range is 2610MHz- 2630MHz, the frequency range overlaps with the downlink operating frequency range of Band7 in FDD mode, that is, overlaps with the frequency range of the first duplex mode, and the overlapping frequency range is 2620MHz-2630MHz.

The duplex mode of the secondary carrier cell is different from the duplex mode of the primary carrier cell, that is, the first duplex mode is different from the second duplex mode, and therefore, the overlapping frequency range is in the second pair. The corresponding frequency point in the working mode is different from the frequency point corresponding to the overlapping frequency range in the first duplex mode. For example, the second duplex mode is TDD mode, the frequency of the secondary carrier is 36950, the frequency band of the secondary carrier is Band36, and the frequency range of the secondary carrier is 600 in the FDD mode, corresponding to the FDD mode. The band is Band2.

Generally, after the UE accesses the primary carrier cell, the first entity sends the corresponding frequency to the UE. For example, the notifying the frequency to the UE includes:

After the UE accesses the primary carrier cell, the first entity sends a Radio Resource Control (RRC) reconfiguration message to the UE, where the RRC reconfiguration message carries the frequency point. information.

Generally, the first entity may notify the UE of the bandwidth corresponding to the overlapping frequency range, and notify the UE according to the frequency, while notifying the information of the frequency point to the UE. The information of the points and the corresponding bandwidth determine the overlapping frequency ranges.

Optionally, in the scenario of the downlink CA, the first data is the first downlink data, and the second data is the second downlink data. Correspondingly, the first entity and the user equipment in the step 102 are The UE interacts with the first data, and the first entity performs modulation on the first downlink data according to the first duplex mode, and sends the modulated first downlink data to the UE. The second entity interacts with the UE by the second data in the step 102, the method includes: the first entity modulating the second downlink data according to the first duplex mode, and modulating the second data The downlink data is sent to the UE by the second entity; or the first entity provides the second downlink data to the second entity to perform modulation according to the first duplex mode, and the modulated second downlink The data is sent by the second entity to the UE, where the interaction between the second entity and the UE is within a frequency range corresponding to the frequency point.

Optionally, after the second entity interacts with the UE by using the second data in the step 102, the method further includes:

The first entity receives an Hybrid Automatic Repeat Request (HQQ) indication for the second downlink data that is sent by the UE according to the feedback timing of the first duplex mode.

In the scenario where the air interface protocol is not changed, the UE considers the downlink CA as the same-mode downlink CA in the first duplex mode. Therefore, for the first downlink data and the second downlink data, the UE may follow the primary The duplex mode of the carrier cell, that is, the feedback timing of the first duplex mode, sends a corresponding uplink HARQ indication to the first entity. Optionally, the first entity determines, according to an uplink HARQ indication for the second downlink data, second downlink data that needs to be retransmitted, and indicates that the second entity is to be modulated according to the first duplex mode. The retransmitted second downlink data is sent to the UE by using the secondary carrier. For example, the primary carrier cell is in a TDD mode, the secondary carrier cell is in an FDD mode, and the first entity downlinks the UE. The data is divided into a first downlink data and a second downlink data, where the first entity modulates the second downlink data according to the TDD mode and sends the second downlink data to the second entity, where the second entity sends the modulated second downlink data through the secondary carrier. Sending to the UE; the primary carrier cell receives an uplink HARQ indication for the second downlink data that is sent by the UE according to the feedback timing of the TDD mode, and the first entity determines, according to the uplink HARQ indication, the second downlink data that needs to be retransmitted. Transmitting the second downlink data that needs to be retransmitted to the eNB of the secondary carrier cell according to the TDD mode, and the second entity will modulate the second required to be retransmitted. Line data to the UE through the secondary carrier.

In the downlink CA scenario, the frequency range in which the first duplex mode corresponding to the secondary carrier and the primary carrier overlap is transmitted to the UE in the first duplex mode, and is sent to the UE through the secondary carrier. The second downlink data is also modulated according to the first duplex mode, so that the UE can receive the downlink data and send the uplink HARQ indication according to the downlink CA of the same standard, and provide a heterogeneous carrier that does not change the existing air interface protocol. Downstream CA solution improves downstream throughput And spectrum resource utilization.

Optionally, in the scenario of the uplink CA, the first data is the first uplink data, and the second data is the second uplink data. Correspondingly, the first entity and the user equipment UE in the step 102 are The first data is exchanged by the first entity, and the first entity receives, by the UE, first uplink data that is modulated by the UE according to the first duplex mode;

The second entity interacting with the UE by the second data in the step 102, the method includes: the first entity receiving, by the second entity, a second modulated by the UE according to the first duplex mode The uplink data, the modulated second uplink data is sent by the UE to the second entity, where the interaction between the second entity and the UE is within a frequency range corresponding to the frequency point .

Optionally, after the second entity interacts with the UE by the second data, the method further includes: sending, by the first entity, the UE to the UE according to a feedback timing of the first duplex mode. The downlink HARQ indication of the two uplink data.

In the foregoing uplink CA scenario, the frequency range in which the first duplex mode corresponding to the primary carrier and the primary carrier are overlapped is sent to the UE in the first duplex mode, so that the UE can follow the uplink of the same standard. The CA method sends data, providing a solution for the heterogeneous carrier uplink CA without changing the existing air interface protocol, improving the uplink throughput rate and spectrum resource utilization.

In yet another alternative embodiment of the invention, the air interface protocol is modified. Correspondingly, before step 102, the method may further include:

Determining, by the first entity, a frequency range of a secondary carrier corresponding to the secondary carrier cell in a frequency corresponding to the second duplex mode;

Notifying the frequency to the UE, the frequency point is used by the UE and the second entity to exchange data according to the second duplex mode.

The frequency range of the secondary carrier overlaps with the frequency range of the first duplex mode in the embodiment that does not need to modify the air interface protocol. In this embodiment, the frequency range of the secondary carrier may be the same as the frequency of the first duplex mode. The frequency ranges overlap, and may also have no overlap with the frequency range of the first duplex mode.

After the UE accesses the primary carrier cell, the first entity sends an RRC weight to the UE. And configuring a message, where the RRC reconfiguration message carries information of the frequency point.

Generally, the first entity may notify the UE of the bandwidth of the secondary carrier while the information of the frequency point is notified to the UE, so that the UE is configured according to the information of the frequency point. And bandwidth determine a frequency range of the secondary carrier.

Optionally, in the scenario of the downlink CA, the first data is the first downlink data, and the second data is the second downlink data.

Correspondingly, the first entity interacts with the user equipment UE in the first data in step 102, including: the first entity modulates the first downlink data according to the first duplex mode, and modulates The first downlink data is sent to the UE;

The step of the second entity interacting with the UE by the second entity in the step 102 includes: the first entity providing the second downlink data to the second entity to perform modulation according to the second duplex mode, and then modulating The second downlink data is sent by the second entity to the UE, where the interaction between the second entity and the UE is within a frequency range corresponding to the frequency point.

Optionally, in this embodiment, the manner in which the UE feeds back the uplink HARQ indication for the second downlink data may be multiple. Optionally, after the second entity interacts with the UE by using the second data, the method further includes:

The first entity receives an uplink HARQ indication for the second downlink data that is sent by the UE according to the feedback timing of the first duplex mode.

Optionally, after the second entity interacts with the UE by using the second data, the UE may also send the second entity to the second entity according to the feedback timing of the second duplex mode. An uplink HARQ indication of the second downlink data, where the second entity may determine, according to the uplink HARQ indication, second downlink data that needs to be retransmitted, or send the uplink HARQ indication to the first entity, by using the first The entity determines, according to the uplink HARQ indication, second downlink data that needs to be retransmitted.

Generally, the feedback timing of the first duplex mode is different from the feedback timing of the second duplex mode. If the UE sends the uplink HARQ indication for the second downlink data according to the feedback timing of the first duplex mode, the UE may specifically modify the feedback timing of the previously stored second duplex mode to the first duplex mode. Feedback timing.

In the scenario of the downlink CA, the entity controlling the primary carrier cell sends the frequency of the heterogeneous secondary carrier to the UE, and sends the downlink data of the first duplex mode to the UE through the primary carrier, and the secondary carrier The wave transmits the downlink data of the second duplex mode to the UE, and provides a solution of the heterogeneous carrier downlink CA, which improves the downlink throughput rate and the spectrum resource utilization rate.

Optionally, in the scenario of the uplink CA, the first data is the first uplink data, and the second data is the second uplink data.

Correspondingly, the first entity interacts with the user equipment UE in the first data in step 102, including: the first entity receiving, by the first entity, the first uplink modulated by the UE according to the first duplex mode Data

The second entity interacting with the UE by the second entity in the step 102, the method includes: the first entity receiving second uplink data from the second entity, where the second uplink data is that the second entity is Transmitting, by the UE, the second uplink data modulated by the UE according to the second duplex mode.

Uplink data provides a solution for heterogeneous carrier uplink CA, which improves uplink throughput and spectrum resource utilization.

In the scenario of the downlink CA in the foregoing embodiments, if the downlink CA does not need to occupy all resources of the secondary carrier, other resources on the secondary carrier may also be used by the UE accessing the secondary carrier cell. Optionally, before the second entity interacts with the UE by the second entity in the step 102, the method further includes:

Optionally, the determining, by the first entity, the downlink CA occupant resource in the secondary carrier, the method includes: the first entity negotiates with the second entity to determine a downlink CA occupant resource in the secondary carrier; or

When the first entity and the second entity are different eNBs, the foregoing negotiation manner may be that the first entity passes the message on the X2 interface, such as an X2 interface request (X2 Setup Request). The message and the X2 interface response (X2 Setup Response) message inform the second entity of the bandwidth required for the second downlink data, and the second entity determines the downlink CA occupation resource on the secondary carrier according to the required bandwidth. Optionally, the X2 interface setup request message and the X2 interface setup response message identify the required bandwidth by using an extension field and the downlink CA occupation resource on the determined secondary carrier.

The pre-configured mode may be that the resources of the secondary carrier that are available for the downlink CA are specified in the configuration of the 0SS, that is, the downlink CA in the secondary carrier occupies resources.

Wherein, when the first entity and the second entity are different eNBs, the manner of the foregoing negotiation may be The first entity sends a message on the X2 interface, such as an X2 Setup Request message and an X2 Setup Response message, to notify the second entity of the bandwidth required for receiving the second uplink data, the second The entity determines the uplink CA occupied resources on the secondary carrier according to the required bandwidth. Optionally, the X2 interface setup request message and the X2 interface setup response message identify the required bandwidth by using an extension field and the determined uplink CA occupation resource on the secondary carrier.

The pre-configured manner may be that the resources available for the CA in the secondary carrier are specified in the configuration of the 0SS, that is, the CA in the secondary carrier occupies resources.

Optionally, when the first entity and the second entity are different eNBs, the first entity and the second entity may interact through the X2 interface. Optionally, the first entity and the second entity may be different boards in the same eNB, and correspondingly, the interaction between the first entity and the second entity may be implemented by using an internal interface of the eNB.

In an optional embodiment of the present invention, the frequency range corresponding to the secondary carrier overlaps with the frequency range of the first duplex mode, and accordingly, the air interface protocol does not need to be modified. In this embodiment, the step 202 may specifically include:

Generally, the frequency range of the secondary carrier corresponding to the secondary carrier cell may be in a frequency range overlapping in a downlink working band of different duplex modes in Table 1, or overlap with a downlink working band in a different duplex mode in Table 1.

For example, the first duplex mode is the FDD mode, the second duplex mode is the TDD mode, and the secondary carrier has a frequency range of 2620 MHz-2630 MHz, and the frequency range is in the downlink operating frequency range of the Band7 of the FDD mode, that is, the first The frequency range of a duplex mode overlaps, and the overlapping frequency range is 2620MHz-2630MHz. For another example, the first duplex mode is the FDD mode, the second duplex mode is the TDD mode, and the secondary carrier has a frequency range of 2610 MHz-2630 MHz, and the frequency range overlaps with the downlink operating frequency range of the Band7 of the FDD mode, that is, It overlaps with the frequency range of the first duplex mode, and the overlapping frequency range is 2620MHz-2630MHz o Optionally, the first entity may further indicate the overlapping frequency range of the second entity, so that the second entity interacts with the UE in the overlapping frequency range.

Correspondingly, after receiving the downlink data, the UE may send an uplink HARQ indication for the downlink data to the first entity according to a feedback timing of the first duplex mode. In this scenario, since the feedback timing of the TDD mode and the feedback timing of the FDD mode are different, not all subframes in the TDD mode carrier can be used for downlink transmission. Therefore, when the first duplex mode is the TDD mode, When the second duplex mode is the FDD mode, the second entity sends the downlink data by using a part of downlink subframes in the secondary carrier, where the location of the downlink subframe is the downlink subframe of the primary carrier.

Therefore, when the first duplex mode is the TDD mode and the second duplex mode is the FDD mode, the second entity uses a partial uplink of the secondary carrier. The subframe receives the uplink data, and the location of the partial uplink subframe is the same as the location of the uplink subframe in the primary carrier.

In this scenario, since the feedback timing of the TDD mode and the feedback timing of the FDD mode are different, not all subframes in the TDD mode carrier can be used for downlink transmission.

Alternatively, the downlink HARQ indication for the uplink data may also be sent to the UE by the first entity according to the feedback timing of the first duplex mode. In this scenario, since the feedback timing of the TDD mode and the feedback timing of the FDD mode are different, not all subframes in the TDD mode carrier can be used for uplink reception. Therefore, when the first duplex mode is the TDD mode. When the second duplex mode is the FDD mode, the second entity receives the uplink data by using some uplink subframes in the secondary carrier, where the location of the partial uplink subframe and the uplink subframe in the primary carrier The location is the same.

In this scenario, since the feedback timing of the TDD mode and the feedback timing of the FDD mode are different, not all subframes in the TDD mode carrier can be used for uplink reception. Therefore, when the first duplex mode is the TDD mode. When the second duplex mode is the FDD mode, the fifth receiving unit receives the uplink data by using a partial uplink subframe in the secondary carrier, where the location of the partial uplink subframe and the uplink subframe in the primary carrier The same location.
