For a UE supporting multi-carrier HSPA, the RNC can configure multiple carriers for the UE in uplink and downlink. In the downlink direction, the base station can simultaneously schedule HS-PDSCH resources on multiple carriers to the UE according to the CQI information of each carrier reported by the UE. Specifically, the process for the base station to perform UE scheduling and CQI information feedback includes:

When the base station schedules HS-PDSCH resources to the UE on a certain carrier, the base station will notify the UE of the configuration information of the HS-PDSCH resources scheduled to the UE through the HS-SCCH corresponding to the carrier; -PDSCH resource sends the HS-DSCH transmission block to the UE; the UE obtains the carrier where the HS-PDSCH resource allocated to it is located and the resource configuration information by detecting the corresponding HS-SCCH, and receives the base station on the corresponding carrier. Its HS-DSCH transmission block; and then carry the ACK/NACK information of the HS-DSCH transmission block and the CQI information of the corresponding carrier to the base station through the HS-SICH paired with the above-mentioned HS-SCCH.

The applicant proposed a method of generating CQI information in the invention patent application "Method for generating CQI information of multi-carrier UE" with the application number of 201110427288.7, which is a method of generating CQI information on another carrier based on the downlink physical channel of UE on one carrier. For a multi-carrier UE, this method enables the UE to estimate the CQI information on another carrier without any downlink channel according to the reception quality of the downlink physical channel on one carrier. In this scenario, how to report the generated CQI information to the system becomes a new problem.

Detailed ways

In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

When the UE supports SUMIMO on a carrier, if the base station allocates dual streams to the UE on the carrier, the base station will carry the allocation information to the UE through the HS-SCCH, and the UE will use the HS-SICH paired with the HS-SCCH and the The paired HS-SICH shares the Midambleshift HS-SICH to feed back the dual-stream ACK/NACK and CQI information to the base station. When the UE is assigned a single stream, the UE will feed back the ACK/NACK information and CQI information of the single stream to the base station through the HS-SICH paired with the HS-SCCH; the HS-SICH that shares Midambleshift with the paired HS-SICH is idle .

When the UE does not support SUMIMO on a carrier, the base station can only allocate a single stream to the UE on the carrier, and carry the allocation information to the UE through the HS-SCCH. The UE will feed back single-stream ACK/NACK information and CQI information to the base station through the HS-SICH paired with the HS-SCCH; the HS-SICH that shares Midambleshift with the paired HS-SICH is idle.

Based on the above, in the present invention, when a UE is allocated a single stream on a scheduled HSDPA carrier, it reports CQI information on another carrier to the base station through the HS-SICH that shares Midambleshift with the paired HS-SICH. That is: when the UE is assigned a single stream, the UE carries the CQI information of another carrier to the base station through the idle HS-SICH. This method only uses the idle HS-SICH to carry the CQI information of another carrier to the base station.

In the present invention, the idle HS-SICH is used to carry the CQI information of other unscheduled carriers for reporting. Specifically, five methods for reporting CQI information are given in the present invention, which will be described in detail through five specific embodiments.

Embodiment one:

FIG. 1 is a specific flowchart of a method for reporting CQI information in Embodiment 1 of the present invention. As shown in Figure 1, the method includes:

Step 101, the RNC pre-configures a corresponding CQI reporting carrier for each carrier in the cell, and sends the configuration information to the UE and the base station.

The carrier correspondence relationship configured by the RNC may be at the cell level or at the UE level. When the corresponding relationship is at the cell level, it means: when the RNC pre-configures the CQI reporting carrier corresponding to carrier i as carrier j, this corresponding relationship is applicable to any UE accessing the cell; the RNC pre-configures one for each carrier in the cell The corresponding CQI is reported to the carrier. Then, the RNC notifies the base station of the configuration information of the CQI reporting carrier corresponding to each carrier in the cell. When a UE accesses a cell, the RNC first configures several carriers for the UE according to the carrier capabilities reported by the UE. For each carrier configured for the UE, the RNC notifies the UE of the configuration information of the carrier corresponding to the carrier.

When the correspondence is at the UE level, it means that for different UEs, the carrier j corresponding to the carrier i may be different. When the corresponding relationship is at the UE level, when the UE accesses, the RNC first configures several carriers for the UE according to the carrier capabilities reported by the UE. Then, for each carrier configured for the UE, the RNC determines the carrier corresponding to the carrier. The RNC notifies the UE of the configuration information of the carriers corresponding to the respective carriers configured for the UE, and notifies the base station at the same time.

Step 102, for an accessed multi-carrier UE, assign the idle HS-SICH of any scheduled carrier of the UE to carry the CQI report carrier's CQI information when the carrier is not scheduled to report the CQI of the carrier, and report to the base station.

When it occurs that multiple scheduled carriers correspond to the same CQI reporting carrier, if the CQI reporting carrier is not scheduled, the base station and the UE can pre-agree that the UE will report the CQI through multiple scheduled carriers corresponding to the CQI reporting carrier. The idle HS-SICH on the carrier with the smallest or largest carrier number carries the CQI information of the unscheduled carrier and reports it to the base station. The above pre-agreed operations between the base station and the UE need to be performed before step 102, and the execution sequence between the agreed operation and step 101 is not limited, and can be performed before, after or at the same time as step 101.

After the configuration in step 101, each carrier i of the multi-carrier UE is configured with a corresponding CQI reporting carrier j; If there is an idle HS-SICH, the idle HS-SICH can carry the CQI information of the carrier j and report it to the base station. Wherein, as mentioned above, the idle HS-SICH of the carrier i is the HS-SICH that shares the same midambleshift with the HS-SICH paired with the HS-SCCH scheduled to the carrier i when the scheduled carrier i is assigned a single flow.

For example, the RNC configures three carriers for the UE: carrier A, carrier B, and carrier C. The CQI reporting carrier corresponding to carrier A is carrier B, the CQI reporting carrier corresponding to carrier B is carrier C, and the CQI reporting carrier corresponding to carrier C is carrier A. When carrier A is not scheduled and needs to upload CQI information through other scheduled carriers, it is determined according to the corresponding relationship that carrier A is the CQI reporting carrier corresponding to carrier C. Therefore, when carrier C is scheduled and assigned a single stream, The idle HS-SICH of the carrier C is used to carry the CQI information of the carrier A and report it to the base station. It may also happen that carrier A is the CQI reporting carrier corresponding to the other two carriers B and C. In this case, if carriers B and C are assigned a single stream at the same time, and carrier A is not scheduled, the base station and UE can agree in advance that the UE can choose a carrier with the largest or smallest carrier number among the two carriers to use. To report the CQI information of carrier A. Rather than the UE reporting the CQI information of the carrier A to the base station through the idle HS-SICH on the carriers B and C at the same time.

Specifically, the information carried on the idle HS-SICH is the same as the general HS-SICH: it carries 1-bit ACK/NACK information and 7-bit CQI information, where the CQI information includes: 1-bit modulation mode information and 6-bit TBSIZE information. The UE reports the 1-bit modulation mode information and 6-bit TBSIZE information of carrier j through the 1-bit modulation mode information and 6-bit TBSIZE information on the idle HS-SICH of carrier i respectively. The 1-bit ACK/NACK information on the idle HS-SICH is idle, and the value of this bit can be freely set between 0 and 1.

The encoding method of the 1-bit ACK/NACK information carried on the HS-SICH and the encoding method of the 7-bit CQI information are the same as those of the general HS-SICH: the 1-bit ACK/NACK information is repeated 32 times; the 7-bit CQI information uses Reed - Muller encoding. The modulation mode of the coded bits on the HS-SICH is the same as that of the general HS-SICH: QPSK modulation is adopted.

Step 103, the base station determines the carrier to which the received CQI information belongs according to the carrier correspondence configured by the RNC.

This step is used to determine the carrier to which the received CQI information belongs at the base station side.

So far, the flow of the method in this embodiment ends. In this embodiment, CQI information of unscheduled carriers can be reported to the base station through the configuration of carrier correspondence.

However, in Embodiment 1, it is necessary to pre-configure a corresponding CQI reporting carrier for each carrier, and then deliver it to the UE and the base station, which consumes certain system resources. At the same time, since only one CQI reporting carrier is configured, there is a lack of flexibility in carrier reporting.

Further, when generating the CQI information of the unscheduled carrier j, the CQI information of the carrier j may be generated according to the downlink physical channel of the carrier i reporting the CQI information of the carrier j.

Embodiment two:

FIG. 2 is a specific flow chart of a method for reporting CQI information in Embodiment 2 of the present invention. As shown in Figure 2, the method includes:

In step 201, the RNC pre-configures two corresponding CQI reporting carriers for each carrier in the cell, and sends the configuration information to the UE and the base station.

Similar to Embodiment 1, the carrier correspondence configured by the RNC may be at the cell level or at the UE level. The specific way of configuring and delivering the carrier correspondence is the same as that in Embodiment 1, and will not be repeated here.

Step 202, for an accessed multi-carrier UE, assign the idle HS-SICH of any scheduled carrier of the UE to carry the CQI report carrier's CQI information when the carrier is not scheduled to report the CQI of the carrier, and report to the base station.

When it occurs that multiple scheduled carriers correspond to the same CQI reporting carrier, if the CQI reporting carrier is not scheduled, the base station and the UE can pre-agreed: the UE reports the CQI carrier through the multiple scheduled carriers corresponding to the CQI reporting carrier. The idle HS-SICH on the carrier with the smallest or largest carrier number carries the CQI information of the unscheduled carrier and reports it to the base station. Similar to Embodiment 1, the above pre-agreed operations between the base station and the UE need to be performed before step 202, and the execution order between the agreed operation and step 201 is not limited, and can be performed before or after step 201 or both at the same time.

In this embodiment, the definition of the idle HS-SICH is the same as that in Embodiment 1, so it will not be repeated here. After the configuration in step 201, each carrier i of the multi-carrier UE is configured with two corresponding CQI reporting carriers j1 and j2; when the carrier j1 or j2 of the UE is not scheduled, the carrier i is scheduled and assigned a single During the flow, the carrier i has an idle HS-SICH, and the idle HS-SICH can carry the CQI information of the carrier j1 or j2 and report it to the base station.

For example, the RNC configures four carriers for the UE: carrier A, carrier B, carrier C, and carrier D. The CQI reporting carriers corresponding to carrier A are carrier B and carrier C, the CQI reporting carriers corresponding to carrier B are carrier C and carrier D, the CQI reporting carriers corresponding to carrier C are carrier D and carrier A, and the CQI reporting carriers corresponding to carrier D are Carrier A and Carrier B. When carrier A is not scheduled and needs to upload CQI information through other scheduled carriers, it is determined according to the corresponding relationship that carrier A is the CQI reporting carrier corresponding to carrier C and carrier D. Therefore, carrier C or carrier D can be scheduled, and When a single stream is allocated, use the idle HS-SICH of the carrier C or D to carry the CQI information of the carrier A and report it to the base station. When carriers C, D, and B are scheduled at the same time and assigned a single stream, since the CQI reporting carriers corresponding to carrier C are D and A, and carrier D is the scheduled carrier, carrier C can only carry the CQI of carrier A information to the base station; since the CQI reporting carriers corresponding to carrier D are A and B, and B is the scheduled carrier, carrier D can only carry the CQI information of carrier A to the base station. In this case, the UE selects the idle HS-SICH on the carrier with the smallest or largest carrier number among carriers C and D to report the CQI information of carrier A to the base station.

In this embodiment, the UE uses the 1-bit ACK/NACK field on the idle HS-SICH to indicate the index number of the carrier to which the CQI information carried by the current HS-SICH belongs. The number in , that is, when the bit is 0, it means that the CQI information of the carrier j1 is carried; when the bit is 1, it means that the CQI information of the carrier j2 is carried. The UE reports the 1-bit modulation mode information and 6-bit TBSIZE information of the carrier indicated by the 1-bit ACK/NACK information to the base station through the 1-bit modulation mode information and 6-bit TBSIZE information on the HS-SICH.

The encoding method of the 1-bit ACK/NACK field carried on the HS-SICH and the encoding method of the 7-bit CQI information are the same as those of the general HS-SICH: the 1-bit ACK/NACK information is repeated 32 times; the 7-bit CQI information adopts Reed - Muller encoding. The modulation mode of the coded bits on the HS-SICH is the same as that of the general HS-SICH: QPSK modulation is adopted.

In step 203, the base station determines the carrier to which the received CQI information belongs according to the carrier correspondence configured by the RNC and the index number of the received CQI reporting carrier.

This step is used to determine the carrier to which the received CQI information belongs at the base station side.

So far, the flow of the method in this embodiment ends. In this embodiment, CQI information of unscheduled carriers can be reported to the base station through the configuration of carrier correspondence.

However, in the second embodiment, it is also necessary to pre-configure the corresponding CQI reporting carrier for each carrier, and then send it to the UE and the base station, which requires certain system resources. At the same time, since two CQI reporting carriers are configured for each carrier, a certain degree of flexibility is added to the reporting and carrying of carrier CQI information.

In the above two embodiments, it is necessary to pre-set the corresponding relationship between carriers. In fact, the configuration of one or two CQI reporting carriers above is only an example, and other numbers of CQI reporting carriers can also be configured as required, which will not be repeated here.

Further, when generating the CQI information of the unscheduled carrier j, the CQI information of the carrier j may be generated according to the downlink physical channel of the carrier i reporting the CQI information of the carrier j.

Embodiment three:

FIG. 3 is a specific flow chart of the method for reporting CQI information in Embodiment 3 of the present invention. As shown in Figure 3, the method includes:

Step 301 , for an unscheduled carrier j allocated to the UE, use an idle HS-SICH of a scheduled carrier i of the UE to carry the CQI information of the carrier j and the serial number of the carrier j.

In this embodiment, the definition of the idle HS-SICH is the same as that in Embodiment 1, so it will not be repeated here. Among the N carriers configured for the UE, the remaining N-1 carriers after removing the carrier i are sorted according to the carrier number, and the ranking of the carrier j in the sorted N-1 carriers Number. For example, the other N-1 carriers are sorted according to the carrier number from small to large, the carrier number with the smallest number is 0; the carrier number with the largest number is N-2.

In this embodiment, certain changes are made to the 1-bit ACK/NACK information and 7-bit CQI information fields carried by the idle HS-SICH. In the idle HS-SICH, from the 1-bit ACK/NACK information and 7-bit CQI information fields, 1 bit is used to carry modulation information, n bits are used to carry TBSIZE offset information, and (7-n) bits are used to carry carrier j number. Wherein, the TBSIZE offset information is an offset value of the TBSIZE of the carrier j relative to the TBSIZE of the carrier i, and n is a preset natural number.

Usually, the maximum number of carriers allocated by the RNC to the UE is 6. In this way, for each UE, except one scheduled carrier i, there are 5 remaining carriers. Therefore, n can take a value of 5 or 4. In this way, the number of bits used to carry the number of carrier j is 2 or 3 bits, which corresponds to the number that can carry 4 or 8 carriers.

Specifically, when n=5, it means that 5 bits indicate the absolute value of the TBSIZE offset C of carrier j, and 2 bits indicate the carrier number of carrier j. 2 bits can represent 4 carriers, indicating that the CQI of the other 4 carriers can be reported to the UE through the carrier i.

When n=4, it indicates that the absolute value of the TBSIZE offset C of the carrier j is indicated by 4 bits, and the carrier number of the carrier j is indicated by 3 bits. 3 bits can represent 8 carriers, indicating that the CQIs of the other 8 carriers can be reported to the UE through the carrier i.

In step 302, the base station determines the carrier j to which the received CQI information belongs according to each carrier configured for the UE and the number of the received carrier j.

This step is used to determine the carrier to which the received CQI information belongs at the base station side.

So far, the flow of the method in this embodiment ends. In this embodiment, CQI information of unscheduled carriers can be reported to the base station through the configuration of carrier correspondence.

In the third embodiment, there is no need to pre-configure and distribute the corresponding relationship for each carrier, which saves system resources; at the same time, one carrier can be used to carry CQI information of multiple carriers, so it also has greater flexibility. However, the way of expressing the CQI information needs to be modified.

Further, when generating the CQI information of the unscheduled carrier j, the CQI information of the carrier j may be generated according to the downlink physical channel of the carrier i reporting the CQI information of the carrier j.

Embodiment four:

FIG. 4 is a specific flow chart of a method for reporting CQI information in Embodiment 4 of the present invention. As shown in Figure 4, the method includes:

Step 401, for the unscheduled carrier j allocated to the UE, use an idle HS-SICH of a scheduled carrier i of the UE to carry the CQI information of the carrier j and report it to the base station; wherein, the base station uses the HS-SICH of the scheduled carrier i The idle bits in the SCCH carry the number of the carrier j to the UE.

In this embodiment, the definition of the idle HS-SICH is the same as that in Embodiment 1, so it will not be repeated here. In this step, the numbering method of the carrier j is the same as that in the third embodiment, and will not be repeated here. The difference from the third embodiment is that the base station uses idle bits of the HS-SCCH of the carrier i to carry the serial number of the carrier j to the UE. After receiving the number of carrier j carried by the HS-SCCH idle bit of carrier i, the UE can clarify the corresponding relationship between carrier i and carrier j. When carrier j is not scheduled and carrier i is assigned a single stream, it can use carrier i The idle HS-SICH carries the CQI information of carrier j and reports it to the base station. Wherein, the number of bits used to carry the carrier number j may be 2 or 3, correspondingly, 4 or 8 carrier numbers can be carried.

The way of using the idle HS-SICH to carry the CQI information of the carrier j is the same as the existing way, that is, the same as that in the first embodiment, and will not be repeated here.

In step 402, the base station determines the carrier j to which the received CQI information belongs according to each carrier configured for the UE and the serial number of the carrier j sent to the UE.

This step is used to determine the carrier to which the received CQI information belongs at the base station side.

So far, the flow of the method in this embodiment ends. In this embodiment, the CQI information of unscheduled carriers can be reported to the base station by carrying the number of the carrier whose CQI information needs to be reported on the HS-SCCH.

Further, when generating the CQI information of the unscheduled carrier j, the CQI information of the carrier j may be generated according to the downlink physical channel of the carrier i reporting the CQI information of the carrier j.

In Embodiment 4, there is no need to pre-configure and deliver the corresponding relationship for each carrier, which saves system resources; one carrier can be used to carry the CQI information of multiple carriers, so it also has certain flexibility; at the same time, it does not need Modify the meaning of each bit on the idle HS-SICH: the meaning of each bit on the idle HS-SICH is the same as that of the general HS-SICH. However, idle bits of the HS-SCCH need to be occupied additionally.

Embodiment five:

FIG. 5 is a specific flow chart of the method for reporting CQI information in Embodiment 5 of the present invention. As shown in Figure 5, the method includes:

In step 501, the RNC configures offset values for each carrier allocated to the UE, and sends them to the UE and the base station.

Offset(i) is used to represent the offset of carrier i, and the value of i is different, and the corresponding offset offset(i) may be different. When the UE accesses, the RNC configures offset(i) for each carrier of the UE, and delivers the configuration information to the UE and the base station.

Step 502, the idle HS-SICH of any scheduled carrier i of the UE is used to carry the CQI information of the unscheduled carrier j, and report it to the base station.

In this embodiment, the definition of the idle HS-SICH is the same as that in Embodiment 1, so it will not be repeated here. In this step, the carrier j is, j=(n(i)+offset(i))mod(N-1), N represents the number of carriers configured by the RNC to the UE; n(i) represents carrying the scheduling information of the carrier i to the UE The number of the subframe where the HS-SCCH channel is located.

Step 503, the base station determines the carrier j to which the received CQI information belongs according to the offset value of the carrier i of the UE configured by the RNC.

The method of determining the specific carrier j is the same as that in step 502, that is, j=(n(i)+offset(i))mod(N-1).

So far, the flow of the method in this embodiment ends. In this embodiment, by configuring the offset of each carrier, the CQI information of the unscheduled carrier can be reported to the base station.
