Description

Information notification, reporting and data receiving method and device

technical field

The present invention relates to the technical field of communication, and in particular to an information notification, reporting and data receiving method and device.

Background technique

The adaptive process of the Physical Downlink Shared Channel (PDSCH) in the current Long Term Evolution (LTE) system is as follows: the user equipment (User Equipment, UE) estimates the Channel State Information (Channel State Information, CSI) channel information; the UE calculates the optimal Rank Indication (RI) and Precoding Matrix Indication (PrecodingMatrix Indication, PMI) through the estimated channel information; the UE calculates the optimal RI based on the estimated channel information and the signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) of the PMI; the UE quantizes the calculated SINR into a 4-bit channel quality indicator (Channel Quality Indicator, CQI); the UE sends the evolved base station (evolution NodeB, eNB ) to report PMI, RI, and CQI values; the eNB determines the number of PDSCH streams and precoding matrix transmitted to the UE according to the RI and PMI reported by the UE, and the eNB allocates a modulation and coding scheme (Modulation and Coding) for the UE according to the CQI value reported by the UE and network conditions Coding Scheme, MCS), used to indicate the current modulation and coding scheme used by the PDSCH; UE receives PDSCH data according to the MCS. Wherein, in the above-mentioned process of quantizing SINR into CQI, the main range of SINR is (-7dB, 19.488dB), and the SINR not in this range is processed in a saturation manner.

In hotspot scenarios, such as relay (Relay) and LTE hotspot improvements (LTE Hotspot Improvements, LTE-Hi) scenarios, the SINR values obtained by UEs are relatively large. For example, under certain conditions, almost 50% of UEs have SINR values exceeding 20dB. However, in the process of quantizing SINR into CQI, when the SINR value exceeds the maximum value of the above-mentioned main interval, it will be processed in a saturation mode. In the saturation mode, the corresponding CQI index is 15, so the UE can only select the CQI corresponding to the index 15 at most. The modulation and coding mode restricts the selection of a higher modulation and coding mode by the UE, thereby affecting system performance.

After introducing 256 Quadrature Amplitude Modulation (Quadrature Amplitude Modulation, QAM), the above problem can be solved, that is, the system performance under the condition of high SINR can be improved. However, after the introduction of 256QAM, the tables used to indicate CQI and MCS will generally be enlarged to support the situation of higher SINR. For example, the CQI table changes from a 4-bit (bit) CQI table to a 5-bit CQI table, and the MCS table changes from a 5-bit MCS table to a 6-bit MCS table. This will increase the overhead of CQI feedback and increase the overhead of MCS indication. Another method is to not change the size of the CQI table and MCS table, but reduce the items corresponding to low SINR, which will reduce the SINR range supported by the CQI and MCS table, for example, on subframes with less interference, the SINR is high , the SINR is very low on subframes that suffer from large interference. For the same UE, the SINR on different subframes varies greatly. Using the above CQI table and MCS table cannot satisfy the SINR variation range on all subframes. .

In the embodiment of the present invention, multiple CSI tables and MCS tables containing different modulation modes and supported SNR ranges are pre-configured on the network side and the UE side, so that the UE can use the corresponding CSI tables to perform measurement on specific measurement resources. Accurate CSI measurement, or use the corresponding MCS table to receive data more efficiently on specific transmission resources.

The base station notifies the UE of at least two resource groups, and the base station notifies the UE of the CSI configuration information corresponding to the at least two resource groups, so that the UE obtains the information in at least one of the at least two resource groups according to the CSI configuration information. CSI corresponding to each resource, and the UE reports the CSI to the base station.

Further, the base station notifies the UE of CSI configuration information corresponding to resources other than the at least two resource groups, so that the UE obtains CSI corresponding to resources other than the at least two resource groups according to the CSI configuration information, and the UE Report the CSI to the base station.

Or, predefine CSI configuration information or CSI candidate sets corresponding to resources other than the at least two resource groups, so that the UE obtains resources other than the at least two resource groups according to the CSI configuration information or CSI candidate sets. The CSI corresponding to the resource, and the UE reports the CSI to the base station. The pre-definition may be pre-set.

The CSI includes: CQI, and/or, precoding matrix indication (PMI), and/or, rank indication (RI).

The CSI candidate set includes a preset CSI table or a set composed of candidates in the preset CSI table.

The CSI configuration information is bitmap signaling, and the set of candidates in the preset CSI table is represented by the bitmap signaling.

The CSI table is: a CQI table, a PMI table or an RI table.

In the embodiment of the present invention, the CSI configuration information notified by the base station to the UE can be any one or more of CQI, PMI, and RI. Measure and report any one or more information of CQI, PMI, and RI based on the configuration information of the information. Therefore, the preset CSI table may also be any one or more of the CQI table, the PMI table, and the RI table.

Specifically, the resource group may be a subframe, a subframe set, a resource block (Resource Block, RB), an RB set, a carrier, a carrier set, a CSI process or a CSI process set, or a channel state information-reference signal (Channel StateInformation- Reference Resource, CSI-RS) or CSI-RS set, access point or access point set. Or the resource group may be subframe, subframe set, resource block, resource block set, carrier, carrier set, CSI process, CSI process set, CSI-RS, CSI-RS set, access point, access point set A combination of at least two of them.

Specifically, the carrier may refer to a component carrier (Component Carrier, CC); the access point may refer to a base station corresponding to a cell, a remote radio unit (Remote Radio Unit, RRU), a remote radio front end (Remote Radio Head, RRH), Macro cells, small cells, micro cells, home base stations, etc.; the CSI process consists of a non-zero power CSI-RS resource and a CSI interference measurement (Channel State Information-Interference Measurement, CSI-IM) resource, wherein the UE according to the non-zero power The CSI-RS obtains the downlink channel, performs interference measurement according to the CSI-IM, calculates and reports the CSI to the base station according to the downlink channel and interference measurement results.

Specifically, the following three CQI tables illustrate three different CQI candidate sets.

Table 1: The first CQI table

Table 2: The second CQI table

Table 3: The third CQI table

In the above example, the difference between the three CQI tables is that the second CQI table contains a higher modulation method (256QAM) than the first CQI table, and the SNR supported by the second CQI table The range is also larger; compared with the first CQI table, the third CQI table contains a higher modulation method (256QAM); compared with the third CQI table, the second CQI table supports The SNR range of is also larger (supporting low SNR range), but the quantization precision of the third CQI table is higher, that is, adjacent items correspond to smaller SNR intervals.

Specifically, when the CQI candidate set includes one of M preset CQI tables, the CQI configuration information is N-bit signaling for indicating one of the M preset CQI tables, where M is A positive integer, N is an integer not less than log2(M), where log2(M) represents the logarithm of M with base 2.

When the CQI candidate set includes a set consisting of candidates in a preset CQI table, the CQI configuration information is bitmap (bitmap) signaling, and the set consisting of candidates in a preset CQI table is Indicated by the bitmap signaling. Specifically, if there are X candidates in the preset CQI table, then the bitmap signaling includes Y bits, where each bit corresponds to at least one candidate, if a certain bit in the bitmap signaling is 1, it means that the candidate item corresponding to this bit belongs to the CQI candidate set; if a certain bit in the bitmap signaling is 0, it means that the candidate item corresponding to this bit does not belong to the CQI candidate set. Where X is a positive integer, Y is a positive integer less than or equal to X. It should be noted that Y can be equal to X, and each bit in the bitmap signaling corresponds to one candidate; Y can also be smaller than X, and at this time, each bit in the bitmap signaling corresponds to one or more candidates. The overhead of CQI configuration information can be reduced.

Specifically, Table 4 lists a preset PMI and RI table for 2 antenna ports:

Table 4: PMI and RI tables

Specifically, the PMI and RI candidate set includes a set consisting of preset PMI and RI candidates, the PMI and RI configuration information is bitmap (bitmap) signaling, and the preset PMI and RI The set of candidate items in the table is represented by the bitmap signaling.

The following two PMI tables illustrate two different PMI candidate sets for 2 antenna ports and 1 data stream:

Table 5: The first PMI table

Form 6: Second PMI Form

In the above example, the difference between the two PMI tables is that the two PMI tables contain different precoding matrices.

Specifically, the PMI candidate set includes one of the two preset PMI tables, and the PMI configuration information is 2-bit signaling for indicating one of the two preset PMI tables.

The following two RI tables illustrate two different RI candidate sets for 4 antenna ports:

Form 7: First RI form

RI value 0 1 1 2 2 3 3 4

Form Eight: Second RI Form

RI value 0 1 1 2

In the above example, the difference between the two RI tables is that the first RI table contains a higher rank than the second RI table.

Specifically, the RI candidate set includes one of two preset RI tables, and the RI configuration information is 2-bit signaling, which is used to indicate one of the two preset RI tables.

Further, the base station notifies the UE of MCS (Modulation and Coding Scheme, Modulation and Coding Scheme) configuration information corresponding to at least two resource groups, so that the UE receives data according to the MCS configuration information.

Still further, the base station notifies the UE of MCS configuration information corresponding to resources other than the at least two resource groups, so that the UE receives data according to the MCS configuration information.

Or, predefine MCS configuration information or MCS candidate sets corresponding to resources other than the at least two resource groups, so that the UE receives data according to the MCS configuration information or the MCS candidate sets.

Specifically, the MCS configuration information is used to indicate an MCS candidate set, and the MCS candidate set may be an MCS table, or a set composed of candidates in the MCS table. The following two MCS tables illustrate two different MCS candidate sets.

Form IX: First MCS Form

Form Ten: Second MCS Form

In the above example, the difference between the two MCS tables is that: compared with the first MCS table, the second MCS table contains a higher modulation mode (256QAM).

The first implementation mode provided by the embodiment of the present invention is introduced below:

Taking the CSI including the CQI as an example below, specific examples are given in different situations, and corresponding beneficial effects are described. For the case where the CSI includes PMI and RI, it is similar to this implementation and will not be repeated here.

Example 1: A resource group refers to a set of subframes.

The base station notifies the UE of at least two subframe sets, and the base station notifies the UE of the CQI configuration information corresponding to the at least two subframe sets, so that the UE obtains at least one of the at least two subframe sets according to the CQI configuration information. The CQI measurement refers to the CQI corresponding to the subframe, and the UE reports the CQI to the base station. The CQI measurement reference subframe refers to a subframe used for CQI measurement.

For example: the base station configures two subframe sets for the UE, subframe set A and subframe set B respectively, and the base station notifies the UE of the CQI configuration information corresponding to the subframe set A and the CQI configuration information corresponding to the subframe set B. Specifically, subframe set A is a subframe with less interference, and subframe set B is a subframe with greater interference. Therefore, the SINR of the signal transmitted on the subframe included in subframe set A is relatively high, and subframe set B The SINR of the signal transmitted on the included subframe is low. In this case, the CQI configuration information corresponding to the subframe set A can be used to indicate the CQI table A, such as the second CQI table or the third CQI table described above. Table, CQI configuration information corresponding to subframe set B can be used to indicate CQI table B, such as the first CQI table described above, where CQI table A is compared with CQI table B, and CQI table A contains modulation higher than 64QAM mode, such as 256QAM.

The UE respectively determines corresponding CQI tables on the two subframe sets according to the CQI configuration information notified by the base station, and measures the CQI of the subframes in the two subframe sets respectively according to the two CQI tables. Specifically, if the CQI measurement reference subframe belongs to subframe set A, then the UE obtains the CQI according to the CQI table A; if the CQI measurement reference subframe belongs to the subframe set B, then the UE obtains the CQI according to the CQI table B.

Further, the base station notifies the UE of the MCS configuration information corresponding to at least two subframe sets, so that the UE receives data according to the MCS configuration information.

Specifically, the UE determines the MCS candidate set according to the MCS configuration information corresponding to the subframe set to which the subframe transmitting data belongs, and receives data according to the MCS candidate set.

Continuing to use the above example, the base station notifies the UE of the MCS configuration information corresponding to subframe set A and the MCS configuration information corresponding to subframe set B. The MCS configuration information corresponding to the subframe set A can be used to indicate the MCS table A, such as the second MCS table described above, and the MCS configuration information corresponding to the subframe set B can be used to indicate the MCS table B, such as the above mentioned The first MCS table of , where MCS table A is compared with MCS table B, MCS table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE respectively determines the corresponding MCS tables of the two subframe sets according to the MCS configuration information notified by the base station, and respectively receives the data transmitted on the subframes in the two subframe sets according to the two MCS tables. Specifically, if the subframe for transmitting data belongs to subframe set A, then the UE determines the modulation and coding scheme of the data according to MCS table A, and then receives the data; if the subframe for transmitting data belongs to subframe set B, then the UE Determine the modulation and coding scheme of the data, and then receive the data.

Further, the base station notifies the UE of the MCS configuration information corresponding to at least two subframe sets, and pre-defines or the base station notifies the UE of the MCS configuration information or MCS candidate sets corresponding to subframes other than the at least two subframe sets, so that the UE Receive data according to MCS configuration information.

Specifically, the UE determines the MCS candidate set according to the MCS configuration information corresponding to the subframe set to which the subframe transmitting data belongs, and receives data according to the MCS candidate set; if the subframe transmitting data does not belong to the at least two subframes any one of the subframe sets, then the UE receives data according to the MCS configuration information or the MCS candidate set corresponding to subframes other than the at least two subframe sets.

Continuing to use the above example, the base station notifies the UE of the MCS configuration information corresponding to subframe set A and the MCS configuration information corresponding to subframe set B, pre-defined or the base station notifies the UE of the MCS configuration corresponding to subframes other than the two subframe sets Information or set of MCS candidates. The MCS configuration information corresponding to the subframe set A can be used to indicate the MCS table A, such as the second MCS table described above, and the MCS configuration information corresponding to the subframe set B can be used to indicate the MCS table B, such as the above mentioned The MCS configuration information corresponding to the subframes other than the two subframe sets can be used to indicate the MCS table B or the MCS candidate set corresponding to the subframes other than the two subframe sets is the MCS Table B, such as the first MCS table mentioned above, wherein MCS table A is compared with MCS table B, and MCS table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE determines the corresponding MCS tables on the two subframe sets according to the MCS configuration information notified by the base station, and receives the data transmitted on the subframes in the two subframe sets respectively according to the two MCS tables; The MCS configuration information or the MCS candidate set corresponding to the subframes other than the two subframe sets of the UE determines the MCS table corresponding to the subframes other than the two subframe sets, and according to the MCS table, receives the Data transmitted on subframes other than the above two subframe sets. Specifically, if the subframe for transmitting data belongs to subframe set A, then the UE determines the modulation and coding scheme of the data according to MCS table A, and then receives the data; if the subframe for transmitting data belongs to subframe set B or does not belong to subframe set A or B, then the UE determines the modulation and coding scheme of the data according to the MCS table B, and then receives the data.

The beneficial effect of this example: Since the interference received by the UE on the subframes of different subframe sets is significantly different, the SINR of the received signal is also significantly different, so different CQIs or different CQIs are used. The MCS configuration can better adapt to different SINR intervals. In addition, since the high SINR can use the CQI table and MCS table including 256QAM, the system throughput can be significantly improved.

Example 2: A resource group refers to a collection of resource blocks.

A resource block refers to a resource unit in a subframe, and a subframe may include multiple resource blocks. Generally, two resource blocks can form a resource block pair; multiple resource blocks can form a resource block group. In the present invention, no matter it is a resource block pair or a resource block group, it can be regarded as a larger resource block, which is also applicable to the present invention. Here, they are collectively referred to as resource blocks.

The base station notifies the UE of at least two resource block sets, and the base station notifies the UE of the CQI configuration information corresponding to the at least two resource block sets, so that the UE obtains resources in at least one resource block set of the at least two resource block sets respectively according to the CQI configuration information The CQI corresponding to the block, and the UE reports the CQI to the base station.

For example: the base station configures two resource block sets for the UE, namely resource block set A and resource block set B, and the base station notifies the UE of the CQI configuration information corresponding to resource block set A and the CQI configuration information corresponding to resource block set B. The specific resource block set A is a resource block with less interference, and the resource block set B is a resource block with greater interference. Therefore, the SINR of the signal transmitted on the resource blocks included in resource block set A is relatively high, and resource block set B The SINR of the signal transmitted on the contained resource blocks is low. In this case, the CQI configuration information corresponding to the resource block set A can be used to indicate the CQI table A, such as the second CQI table or the third CQI described above. Table, the CQI configuration information corresponding to resource block set B can be used to indicate CQI table B, such as the first CQI table described above, where CQI table A is compared with CQI table B, and CQI table A contains modulation higher than 64QAM mode, such as 256QAM.

The UE respectively determines the corresponding CQI tables on the two resource block sets according to the CQI configuration information notified by the base station side, and measures the CQI of the resource blocks in the two resource block sets respectively according to the two CQI tables. Specifically, if the resource block for which CQI measurement needs to be performed belongs to resource block set A, then the UE obtains CQI according to CQI table A; if the resource block for which CQI measurement needs to be performed belongs to resource block set B, then the UE obtains CQI according to CQI table B.

Further, the base station notifies the UE of the MCS configuration information corresponding to at least two resource block sets, so that the UE receives data according to the MCS configuration information.

Continuing with the above example, the base station notifies the UE of the MCS configuration information corresponding to resource block set A and the MCS configuration information corresponding to resource block set B. The MCS configuration information corresponding to the resource block set A can be used to indicate the MCS table A, such as the second MCS table described above, and the MCS configuration information corresponding to the resource block set B can be used to indicate the MCS table B, such as the above-mentioned The first MCS table of , where MCS table A is compared with MCS table B, MCS table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE respectively determines the MCS tables corresponding to the two resource block sets according to the MCS configuration information notified by the base station, and receives the data transmitted on the resource blocks in the two resource block sets respectively according to the two MCS tables.

Receive the data transmitted on the resource group according to the MCS candidate set corresponding to the resource group to which the resource for transmitting data belongs, specifically, for example:

If the resource block for transmitting data belongs to resource block set A, the UE determines the modulation and coding scheme of the data according to MCS table A, and then receives the data; if the resource block for transmitting data belongs to resource block set B, then the UE determines the data modulation and coding scheme according to MCS table B Modulate the coding scheme to receive data.

Or, select an MCS candidate set corresponding to a resource group according to preset rules to receive data, for example, the following two methods can be used:

Mode 1: Select an MCS candidate set corresponding to a resource group to which a resource for transmitting data belongs according to a preset rule to receive the data. For example, if the resource block with the lowest number in the resource blocks for data transmission belongs to resource block set A, then the UE determines the modulation and coding scheme of the data according to the MCS table A, and then receives the data; if the resource block with the lowest number in the resource blocks for data transmission belongs to Resource block set B, then the UE determines the modulation and coding scheme of the data according to the MCS table B, and then receives the data. It should be noted that the resource block with the lowest number among the resource blocks for data transmission mentioned here may also be other predefined resource blocks, for example, the resource block with the highest number among the resource blocks for data transmission.

Mode 2: The data is received according to the MCS candidate set corresponding to a resource group containing the most resources for transmitting data. For example, if the number of resource blocks belonging to resource block set A in the resource blocks for transmitting data is greater than the number of resource blocks belonging to resource block set B in the resource blocks for transmitting data, then the UE determines the modulation and coding scheme of the data according to the MCS table A, Then receive data; if the number of resource blocks belonging to resource block set B in the resource blocks for transmitting data is greater than the number of resource blocks belonging to resource block set A in the resource blocks for transmitting data, then the UE determines the modulation and coding of the data according to MCS table B plan to receive data. If the number of resource blocks belonging to resource block set B in the resource blocks for transmitting data is equal to the number of resource blocks belonging to resource block set A in the resource blocks for transmitting data, then the UE determines the data according to the predefined MCS table A or MCS table B Modulation and coding scheme, and then receive data.

The beneficial effect of this example: Since the interference received by the UE on the resource blocks of different resource block sets is significantly different, the SINR of the received signal is also significantly different, so different CQIs or different CQIs are used. The CQI and MCS configurations can better adapt to different SINR intervals. In addition, since the high SINR can use the CQI table and MCS table including 256QAM, the system throughput can be significantly improved.

Example 3: A resource group refers to a carrier or a set of carriers.

Multiple carriers may exist in a communication system (such as an LTE system). In this example, a resource group refers to a carrier as an example, and the same can be extended to a resource group referring to a set of carriers.

The base station notifies the UE of at least two carriers, and the base station notifies the UE of the CQI configuration information corresponding to the at least two carriers, so that the UE obtains the CQI corresponding to at least one of the at least two carriers according to the CQI configuration information, and the UE reports the CQI to the base station.

For example, the base station configures two carriers for the UE, namely carrier A and carrier B, and the base station notifies the UE of the CQI configuration information corresponding to carrier A and the CQI configuration information corresponding to carrier B. The specific carrier A is a carrier with less interference, for example, the carrier of the adjacent cell is a new type of carrier (the new type of carrier has less cell specific reference signals (cell specific reference signal, CRS) or no CRS, so the generated The interference is relatively small), carrier B is a carrier with greater interference, so the SINR of the signal transmitted on carrier A is higher, and the SINR of the signal transmitted on carrier B is lower. In this case, the CQI configuration information corresponding to carrier A It can be used to indicate CQI table A, such as the second CQI table or the third CQI table described above, and the CQI configuration information corresponding to carrier B can be used to indicate CQI table B, such as the first CQI table described above, The CQI table A is compared with the CQI table B, and the CQI table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE respectively determines the corresponding CQI tables on the two carriers according to the CQI configuration information notified by the base station, and measures the CQIs of the two carriers respectively according to the two CQI tables. Specifically, if the carrier that needs to measure the CQI is carrier A, then the UE obtains the CQI according to the CQI table A; if the carrier that needs to measure the CQI is the carrier B, then the UE obtains the CQI according to the CQI table B.

Further, the base station notifies the UE of the MCS configuration information corresponding to at least two carriers, so that the UE receives data according to the MCS configuration information.

Continuing with the above example, the base station notifies the UE of the MCS configuration information corresponding to carrier A and the MCS configuration information corresponding to carrier B. The MCS configuration information corresponding to carrier A can be used to indicate MCS table A, such as the second MCS table described above, and the MCS configuration information corresponding to carrier B can be used to indicate MCS table B, such as the first MCS table described above Table, where MCS Table A is compared with MCS Table B, MCS Table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE respectively determines the MCS tables corresponding to the two carriers according to the MCS configuration information notified by the base station, and receives the data transmitted on the subframes in the two carriers respectively according to the two MCS tables. Specifically, if the carrier for transmitting data is carrier A, then the UE determines the modulation and coding scheme of the data according to MCS table A, and then receives the data; if the carrier for transmitting data is carrier B, then the UE determines the modulation and coding scheme of the data according to MCS table B , and then receive data.

Beneficial effects of this example: Since the interference received by the signal received by the UE is significantly different on different carriers, the SINR of the received signal is also significantly different, so different CQIs or different CQI and MCS configurations are used It can better adapt to different SINR intervals. In addition, since the high SINR can use the CQI table and MCS table including 256QAM, the system throughput can be significantly improved.

Example 4: A resource group refers to a CSI process or a set of CSI processes.

Multiple CSI processes may exist in a communication system (such as an LTE system). In this example, a resource group refers to a CSI process as an example, and the same can be extended to a resource group referring to a set of CSI processes.

The base station notifies the UE of at least two CSI processes, the base station notifies the UE of the CQI configuration information corresponding to the at least two CSI processes, so that the UE obtains the CQI corresponding to at least one of the at least two CSI processes according to the CQI configuration information, and the UE sends The base station reports the CQI.

For example: the base station configures two CSI processes for the UE, namely CSI process A and CSI process B, and the base station notifies the UE of the CQI configuration information corresponding to CSI process A and the CQI configuration information corresponding to CSI process B. Specifically, the interference measured on the CSI-IM included in CSI process A is relatively small. The interference is large, for example, assuming that the adjacent cell is in the state of transmitting data, that is, assuming that the adjacent cell generates interference, so the SINR measured according to the CSI process A is high, and the SINR measured according to the CSI process B is low. In this case Next, the CQI configuration information corresponding to CSI process A can be used to indicate CQI table A, such as the second CQI table or the third CQI table described above, and the CQI configuration information corresponding to CSI process B can be used to indicate CQI table B, For example, the first CQI table mentioned above, wherein CQI table A is compared with CQI table B, and CQI table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE respectively determines the CQI tables corresponding to the two CSI processes according to the CQI configuration information notified by the base station, and measures the CQIs of the two CSI processes respectively according to the two CQI tables. Specifically, if the CSI process that requires CQI measurement is CSI process A, then the UE obtains CQI according to CQI table A; if the CSI process that requires CQI measurement is CSI process B, then the UE obtains CQI according to CQI table B.

Further, the base station notifies the UE of the MCS configuration information corresponding to at least two CSI processes, so that the UE receives data according to the MCS configuration information.

Continuing with the above example, the base station notifies the UE of the MCS configuration information corresponding to CSI process A and the MCS configuration information corresponding to CSI process B. The MCS configuration information corresponding to CSI process A can be used to indicate MCS table A, such as the second MCS table described above, and the MCS configuration information corresponding to CSI process B can be used to indicate MCS table B, such as the second MCS table described above. An MCS table, wherein MCS table A is compared with MCS table B, and MCS table A contains a modulation scheme higher than 64QAM, such as 256QAM.

The UE determines the MCS tables corresponding to the two CSI processes according to the MCS configuration information notified by the base station, and receives data according to the MCS tables and the dynamic signaling sent by the base station. Specifically, the base station indicates the CSI process corresponding to the data transmission through dynamic signaling. If the CSI process corresponding to the data transmission is CSI process A, then the UE determines the modulation and coding scheme of the data according to the MCS table A, and then receives the data; if the data transmission The corresponding CSI process is CSI process B, then the UE determines the modulation and coding scheme of the data according to the MCS table B, and then receives the data.

or,

The base station indicates the corresponding MCS configuration information for data transmission through dynamic signaling, so that the UE determines the corresponding MCS table to receive data according to the MCS configuration information, that is, the base station does not need to notify the UE in advance of at least two resource groups and the corresponding resource groups for each resource group. MCS configuration information, the UE does not need to determine the resource group to which the resource for transmitting data belongs. Beneficial effects of this example: Since the interference measured by the UE is significantly different according to different CSI processes, the SINR measured is also significantly different, so different CQIs or different CQI and MCS configurations can better adapt to different The SINR interval. In addition, since the high SINR can use the CQI table and the MCS table including 256QAM, the system throughput can be significantly improved.

In the LTE system, the above dynamic signaling may be multiplexing the existing signaling 'PDSCH RE Mapping and Quasi-Co-Location indicator' (PDSCH RE Mapping and Quasi-Co-Location Indicator, PQI for short). Specifically, the base station notifies the UE of the MCS configuration information corresponding to at least two CSI processes, and sends PDSCH RE mapping and quasi-colocation indication (PQI for short) to the UE, so that the UE receives data according to the MCS configuration information and PQI. For example, the UE determines a CSI-RS according to the PQI, the UE determines that the CSI process including the CSI-RS is the CSI process corresponding to data transmission, and receives data according to the MCS table corresponding to the CSI process.

Further, if there are two or more CSI processes containing the CSI-RS, then the UE selects one of the CSI processes containing the CSI-RS according to predefined rules, and according to the MCS corresponding to the CSI process The form receives the data. Specifically, the pre-defined rule may be any of the following: the MCS configuration information number corresponding to the selected CSI process is among the MCS configuration information numbers corresponding to the two or more CSI processes containing the CSI-RS The largest or smallest; the selected CSI process number is the largest or smallest among the two or more CSI process numbers that contain the CSI-RS; the selected CSI process includes a CSI-IM number that is The largest or smallest CSI-IM number contained in the two or more CSI processes containing the CSI-RS; the MCS table indicated by the MCS configuration information corresponding to the selected CSI process contains information higher than 64QAM The modulation method or does not contain a modulation method higher than 64QAM.

Preferably, the base station notifying the UE of the MCS configuration information corresponding to at least two CSI processes respectively includes: the MCS configuration information corresponding to the CSI processes including the same CSI-RS is the same.

Preferably, the base station notifying the UE of the CQI configuration information corresponding to at least two CSI processes respectively includes: the CQI configuration information corresponding to the CSI processes including the same CSI-RS is the same.

Preferably, the base station notifying the UE of the CSI configuration information corresponding to at least two CSI processes respectively includes: the CSI configuration information corresponding to the CSI processes including the same CSI-RS is the same.

The beneficial effect of this example also includes: multiplexing the existing dynamic signaling, avoiding the introduction of additional dynamic signaling overhead.

Example 5: A resource group refers to a CSI-RS or a CSI-RS set.

Multiple CSI-RSs may exist in a communication system (such as an LTE system). In this example, a resource group refers to a CSI-RS as an example, and the same can be extended to a resource group referring to a CSI-RS set.

The base station notifies the UE of at least two CSI-RSs, and the base station notifies the UE of the CQI configuration information corresponding to the at least two CSI-RSs, so that the UE obtains the CSI-RS corresponding to at least one of the at least two CSI-RSs according to the CQI configuration information. CQI, the UE reports the CQI to the base station.

For example, the base station configures two CSI-RSs for the UE, namely CSI-RS A and CSI-RS B, and the base station notifies the UE of the CQI configuration information corresponding to CSI-RS A and the CQI configuration information corresponding to CSI-RS B. The interference measured on the CSI-IM contained in the specific CSI-RS A is relatively small. The interference obtained is relatively large. For example, assuming that the adjacent cell is in the state of transmitting data, that is, it is assumed that the adjacent cell generates interference, so the SINR obtained according to the measurement of CSI-RS A is high, and the SINR obtained according to the measurement of CSI-RS B is low. In this case, the CQI configuration information corresponding to CSI-RS A can be used to indicate CQI table A, such as the second CQI table or the third CQI table described above, and the CQI configuration information corresponding to CSI-RS B can be used When indicating CQI table B, such as the first CQI table mentioned above, wherein CQI table A is compared with CQI table B, CQI table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE respectively determines the CQI tables corresponding to the two CSI-RSs according to the CQI configuration information notified by the base station, and measures the CQIs of the two CSI-RSs respectively according to the two CQI tables. Specifically, if the CSI-RS that needs to perform CQI measurement is CSI-RS A, then the UE obtains CQI according to CQI table A; if the CSI-RS that needs to perform CQI measurement is CSI-RS B, then the UE obtains CQI according to CQI table B .

Further, the base station notifies the UE of the MCS configuration information corresponding to the at least two CSI-RSs, so that the UE receives data according to the MCS configuration information.

Continuing to use the above example, the base station notifies the UE of the MCS configuration information corresponding to CSI-RS A and the MCS configuration information corresponding to CSI-RS B. The MCS configuration information corresponding to CSI-RS A can be used to indicate MCS table A, such as the second MCS table described above, and the MCS configuration information corresponding to CSI-RS B can be used to indicate MCS table B, such as described above The first MCS table of , where MCS table A is compared with MCS table B, MCS table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE respectively determines the MCS tables corresponding to the two CSI-RSs according to the MCS configuration information notified by the base station, and receives data according to the MCS tables and the dynamic signaling sent by the base station. Specifically, the base station indicates the CSI-RS corresponding to the data transmission through dynamic signaling. If the CSI-RS corresponding to the data transmission is CSI-RS A, then the UE determines the modulation and coding scheme of the data according to the MCS table A, and then receives the data; If the CSI-RS corresponding to the data transmission is CSI-RS B, then the UE determines the modulation and coding scheme of the data according to the MCS table B, and then receives the data.

or,

The base station instructs the MCS configuration information corresponding to data transmission through dynamic signaling, so that the UE determines the corresponding MCS table to receive data according to the MCS configuration information, without the UE needing to judge the CSI-RS type.

In the LTE system, the dynamic signaling may be multiplexing the existing signaling 'PDSCH RE Mapping and Quasi-Co-Location indicator' (PDSCH RE Mapping and Quasi-Co-Location Indicator).

The beneficial effect of this example: the downlink channels of different access points are obtained based on different CSI-RS measurements, and the signal-to-noise ratios of data sent by different access points will be significantly different, so using different CQI and MCS tables can improve System throughput.

Example 6: The resource group is an access point or a collection of access points.

Taking access point combination as an example, the base station notifies the UE of at least two access point sets, and the base station notifies the UE of the CQI configuration information corresponding to the at least two access point sets, so that the UE obtains at least two access point sets respectively according to the CQI configuration information. The CQI corresponding to each access point in at least one access point set in the access point set, and the UE reports the CQI to the base station.

For example: the base station configures two access point sets for the UE, namely the access point set A and the access point set B, and the base station notifies the UE of the CQI configuration information corresponding to the access point set A and the CQI configuration corresponding to the access point set B information. Specifically, access point set A is an access point with less interference, and access point set B is an access point with greater interference. Therefore, the SINR of signals transmitted on access points included in access point set A is relatively low High, the SINR of the signal transmitted on the access point contained in the access point set B is low, in this case, the CQI configuration information corresponding to the access point set A can be used to indicate the CQI table A, such as the above-mentioned The second CQI table or the third CQI table, the CQI configuration information corresponding to the access point set B can be used to indicate the CQI table B, such as the first CQI table described above, where CQI table A is compared with CQI table B , CQI Table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE respectively determines corresponding CQI tables on the two access point sets according to the CQI configuration information notified by the base station, and measures the CQIs of the access points in the two access point sets respectively according to the two CQI tables. Specifically, if the CQI measurement reference access point belongs to the access point set A, then the UE obtains the CQI according to the CQI table A; if the CQI measurement reference access point belongs to the access point set B, then the UE obtains the CQI according to the CQI table B.

Further, the base station notifies the UE of the MCS configuration information corresponding to at least two access point sets, so that the UE receives data according to the MCS configuration information.

Continuing with the above example, the base station notifies the UE of the MCS configuration information corresponding to AP set A and the MCS configuration information corresponding to AP set B. The MCS configuration information corresponding to the access point set A can be used to indicate the MCS table A, such as the second MCS table described above, and the MCS configuration information corresponding to the access point set B can be used to indicate the MCS table B, such as the above-mentioned The first MCS table, wherein MCS table A is compared with MCS table B, and MCS table A contains a modulation method higher than 64QAM, such as 256QAM.

The UE respectively determines the corresponding MCS tables of the two AP sets according to the MCS configuration information notified by the base station, and respectively receives the data transmitted by the APs in the two AP sets according to the two MCS tables. Specifically, if the access point that transmits data belongs to access point set A, then the UE determines the modulation and coding scheme of the data according to MCS table A, and then receives the data; if the access point that transmits data belongs to access point set B, then the UE Determine the modulation and coding scheme of the data according to the MCS table B, and then receive the data.

The beneficial effect of this example is that the signal-to-noise ratios of the data sent by different access points will be obviously different, so the system throughput can be improved by using different CQI and MCS tables.

For example, taking the resource group as a combination of subframe sets and CSI processes as an example, the base station notifies the UE of at least two subframe sets and/or at least two CSI processes, and the base station notifies the UE of at least two of the subframe sets and the CSI processes The CQI configuration information corresponding to the combinations of the subframes, so that the UE obtains the CQI corresponding to the combination of at least two subframe sets and the CSI process according to the CQI configuration information, and the UE reports the CQI to the base station.

The beneficial effect of this example is that the signal-to-noise ratios of the data sent by different access points will be obviously different, so the system throughput can be improved by using different CQI and MCS tables.

The beneficial effects of this example are: the beneficial effects that can be achieved in Examples 1-6 can be achieved.

The second implementation mode provided by the embodiment of the present invention is introduced below:

The base station notifies the UE or the UE pre-defines the CQI configuration information corresponding to the reporting mode based on the Physical Uplink Shared Channel (PUSCH) and the reporting mode based on the Physical Uplink Control Channel (PUCCH), so that the UE can be configured according to different CQI The configuration information respectively determines the corresponding CQI candidate set, and respectively uses the corresponding CQI candidate set to obtain the CQI that needs to be reported based on the PUSCH reporting mode and/or the CQI that needs to be reported based on the PUCCH reporting mode, and reports the corresponding CQI to the base station. The CQI candidate sets determined according to different CQI configuration information may be the same or different; the UE uses the PUSCH to report the CQI based on the PUSCH reporting mode; the UE can use the PUCCH or PUSCH to report the CQI based on the PUCCH reporting mode. The further PUSCH-based reporting mode may also be called "aperiodic reporting mode"; the PUCCH-based reporting mode may also be called "periodic reporting mode". Therefore, this embodiment can also be expressed as: the base station notifies the UE or the UE pre-defines the CQI configuration information corresponding to the aperiodic reporting mode and the periodic reporting mode respectively, so that the UE determines the corresponding CQI candidate sets according to different CQI configuration information, and respectively uses The corresponding CQI candidate set obtains the CQI that needs to be reported in the aperiodic reporting mode and/or the CQI that needs to be reported in the periodic reporting mode, and reports the corresponding CQI to the base station. Wherein, the CQI candidate sets respectively determined according to different CQI configuration information may be the same or different; the UE uses the PUSCH to report the CQI in the aperiodic reporting mode; the UE may use the PUCCH or PUSCH to report the CQI in the periodic reporting mode.

Specifically, it is assumed that the CQI of at least two resource groups reported based on the PUSCH reporting mode uses CQI table A, and the CQI of at least two resource groups reported based on the PUCCH reporting mode uses CQI table B. Compared with CQI table A and CQI table B, CQI table A contains a higher modulation method (256QAM), and the range of signal-to-noise ratio supported by CQI table A is also larger, and CQI table A contains more items, such as the second CQI table mentioned above . CQI table B may be, for example, the first CQI table described above. Specifically, CQI form A may have 32 items, and CQI form B may have 16 items. That is, each CQI reported based on the PUSCH has at most 5 bits, and each CQI reported based on the PUCCH has at most 4 bits.

The beneficial effect of this implementation is that the number of information bits carried by the PUCCH is small and strictly limited, and the CQI report using the 4-bit CQI table will not change the number of information bits carried by the PUCCH, which has an impact on the system very small. However, the number of information bits carried by the PUSCH is large, and using a 5-bit CQI table for CQI reporting can improve the accuracy of CQI reporting, which is beneficial to improving system throughput.

It should be noted that the above two implementation manners can be combined to obtain a third implementation manner provided by the embodiment of the present invention:

That is, the base station notifies the UE or the UE pre-defines the CSI configuration information corresponding to the CQI of at least two resource groups reported based on the PUSCH, and the CSI configuration information corresponding to the CQI of at least two resource groups reported based on the PUCCH reporting mode, so that the UE according to the base station The notified CSI configuration information obtains the CQI of at least two resource groups reported based on the PUSCH reporting mode and the CQI of at least two resource groups reported based on the PUCCH reporting mode corresponding to different resource groups, and the UE reports to the base station based on the PUSCH and PUCCH respectively Corresponding CQI.

Specifically, assume that the CQI of resource group A reported based on PUSCH uses CQI table A, assume that the CQI of resource group B reported based on PUSCH uses CQI table B, and the CQI of at least two resource groups reported based on the PUCCH reporting mode also use CQI table b. Compared with CQI table B, CQI table A contains a higher modulation mode (256QAM), and the range of signal-to-noise ratio supported by CQI table A is also larger, and CQI table A contains more items. For example, you can is the second CQI table described above. CQI table B may be, for example, the first CQI table described above. Specifically, CQI form A may have 32 items, and CQI form B may have 16 items. That is, each CQI reported based on the PUSCH has at most 5 bits, and each CQI reported based on the PUCCH has at most 4 bits.
