Description

Information configuration, information feedback method, base station and terminal

Technical field

The present application relates to, but is not limited to, communication management technologies in the field of communications, and in particular, an information configuration, an information feedback method, a base station, and a terminal.

Background technique

The pilot is generally a cell-level full-dimensional non-precoded pilot. Since multiple users in the cell share measurement pilots, the general transmit antenna and the measurement pilot port are one-to-one mapping, and no pilot is dropped. Peacekeeping precoding processing. The method of channel measurement based on such pilots is relatively simple and singular. The CSI (Channel State Information) quantization feedback technique is also based on RI (Rank Indication, Rank Indication)/PMI (Pre-coding Matrix Indication)/CQI (Channel Quality Indicator, The implicit feedback method of the channel quality indicator), and the codebook corresponding to the PMI is relatively fixed. In the case of the specified port number/antenna number, the base station and the terminal are agreed upon when the codebook is standardized.

With the development of MIMO technology, a large number of new technologies have emerged, such as measurement techniques based on various precoding CSI-RS (Channel State Information-Reference Signal) pilots, which will be flexible. UE specific pilot configuration and measurement support various new feedback technologies, such as horizontal and vertical fractal dimension feedback techniques, channel dimensionality reduction feedback techniques, sector virtualization techniques, beam selection techniques, and the like. Some new pilot and feedback technologies generally only have good performance in some scenarios/target UEs, and in some scenarios, performance loss occurs, so that various measurements and feedbacks can be made very flexible. It is very important to guarantee good performance while guaranteeing good measurement and feedback robustness. With the related technology, if the UE is to support channel measurement of multiple sets of CSI-RSs, or to support multiple feedback modes, the general method is that the base station configures the terminal to use multiple CSI Process for the same channel for measurement, and each process configuration is different. Pilot and measurement feedback methods. However, one obvious problem with this approach is that this approach does not allow flexible configuration of the channel.

Preferred embodiment of the invention

Embodiment 1

An embodiment of the present invention provides an information configuration method, which is applied to a base station. As shown in FIG. 1, the method includes:

Step 11: Configure N channel information processes for periodic CSI feedback of the terminal physical uplink control channel PUCCH.

Step 12: Configure M channel information processes for aperiodic CSI feedback of the terminal physical uplink shared channel PUSCH, where M and N are positive integers greater than or equal to zero, and at least one of M and N is not zero.

The execution steps of the

above steps

11 and 12 may be performed simultaneously or at different times.

In general, the design of the channel information (CSI) process of the related art is as shown in FIG. 2. One CSI process includes channel measurement resource configuration, configuration of interference measurement resources, and some other configurations. The same CSI process is applied to both periodic CSI measurement feedback on PUCCH and aperiodic CSI measurement and feedback on PUSCH.

In other words, the two different CSI feedback types share a set of CSI processes, using the same A set of channel measurement resource configuration and interference resource configuration. This approach limits flexibility because the differentiation of measurement and feedback characteristics on PUCCH and PUSCH is relatively large.

Example 1-1

In the solution described in this embodiment, the CSI process of the related art is split, and the CSI process (or subprocess) that is split into PUCCH periodic feedback and the CSI process (or called subprocess) of the PUSCH aperiodic feedback are split. , subprocess). The channel measurement and feedback parameter configuration corresponding to the identical CSI process is no longer used, as shown in FIG. 3.

The base station side can be implemented in the following manner: the base station configures N channel information processes for the PUCCH period feedback, and the base station configures M channel information processes for the PUSCH aperiodic CSI feedback.

Here, N and M are integers. Generally, in order to reduce complexity, N and M can be controlled within a range of not more than 4, and can be determined according to the capability level of the terminal. Different terminals support configured PUCCH period feedback maximum number of CSI processes and PUSCH non- The number of maximum processes for periodic feedback is different.

N and M can also be configured with different values, for example, (N=1, M=3), (N=3, M=4), and the same value can be configured, for example, (N=3, M= 3), but the corresponding control signaling is different configuration signaling. The configuration flexibility of the CSI Process corresponding to different feedback types can be guaranteed.

The N channel information process is configured for the PUCCH period feedback, and the base station needs to configure corresponding information, such as channel measurement resource information, interference measurement resource information, and the like. details as follows:

The channel measurement resource information mainly refers to CSI-RS pilot configuration information applied to channel measurement, and there may be two types of pilot, periodic CSI-RS pilot and aperiodic CSI-RS pilot. Among them, the former is periodically transmitted, and the latter is triggered aperiodically.

Optionally, the base station configures one or more sets of periodic CSI-RS pilot resources for channel measurement for each CSI process configured for PUCCH period feedback, and configures non-periodic pilots for the CSI process. The periodic CSI-RS pilot configuration information includes: a periodic parameter of a periodic CSI-RS pilot, such as 5ms/10ms/20ms/40ms/80ms, and an offset parameter, that is, a subframe offset information, which is used to stagger the same period. CSI-RS to avoid conflicts. The configuration of the periodic CSI-RS also needs to include the port information of the pilot, such as port 15, 16 (2 ports), ports 15, 16, 17, 18 (4 ports), ports 15 to 22 (8 ports), and the like, and The Pattern information in a Resource Block (RB), generally there are multiple Patterns in a specific sending position in an RB, which can be selected. One step is to avoid different base stations, and the measurement pilots of different terminals send collisions.

One or more sets of periodic pilot measurement resources can be configured for the same PUCCH CSI process. When multiple sets are configured, the terminal performs CSI quantization and feedback based on measurement resource selection, measurement resource joint measurement and other technologies.

The interference measurement resource information mainly refers to resource location information used for interference measurement, and is generally indicated by an Interference Measurement Resource (IMR) configuration. It mainly indicates the resource location of the time-frequency domain. Generally, the same PUCCH CSI process only needs to configure one set of IMRs. However, for some special cases, if you want to measure multiple different inter-user interferences, you can configure multiple sets of IMRs and associate them with the same or different channel measurement resources.

In addition, the base station needs to independently configure some other parameters, such as feedback mode, feedback period, sub-frame offset of the feedback report, etc., for different PUCCH period feedback CSI Process.

The M channel information process is configured for the non-periodic feedback of the PUSCH, and the base station needs to configure corresponding information, such as channel measurement resource information, interference measurement resource information, and the like. details as follows:

Channel measurement resource information configuration: The base station configures one or more sets of periodic CSI-RS pilot resources or aperiodic CSI-RS pilot resources for channel measurement for each CSI process fed back by the PUCCH period, where the periodic pilot can follow the front The related method is configured. The aperiodic CSI-RS pilot has some differences from the periodic CSI-RS. There is no need to configure the period, the subframe position and other parameters, but the port number and the Pattern information still need to be configured. / density and other information.

Interference measurement resource information configuration: indicated by the Interference Measurement Resource (IMR) configuration; indicates the resource location of its time-frequency domain. Generally, the same PUCCH CSI process only needs to configure one set of IMRs. However, for some special cases, if you want to measure multiple different inter-user interferences, you can configure multiple sets of IMRs and associate them with the same or different channel measurement resources.

Other configurations: Different PUSCH aperiodic feedback CSI Process independently configures some other parameters, such as feedback mode.

Example 1-2

The embodiment provides an information configuration method, which is applied to a base station, and includes: the base station configures at least one channel information process for the X feedback modes of the terminal; where X is greater than or equal to 1.

In the solution described in this embodiment, the PUCCH cycle in the CSI Process of the related art will be The same configuration of the channel measurement resource and the interference measurement resource of the feedback and PUSCH aperiodic feedback is extended to a differentiated configuration, and although the same CSI Process is used, different measurement resources are supported, as shown in FIG. 4 .

Method 1: When X is one, the different feedback types (PUCCH period feedback and PUSCH aperiodic feedback) of the channel information process of the base station configure channel measurement resources by using different signaling, which may include the following sub-methods:

Sub-method 1: The base station configures a set of shared period CSI-RS pilots for PUCCH periodic feedback and PUSCH aperiodic feedback, and the base station also configures B sets of aperiodic CSI-RSs for PUSCH aperiodic feedback only for PUSCH aperiodic feedback. Pilot. A and B are integers. It is worth noting that A and B cannot be 0 at the same time.

Sub-method 2: The base station configures a set of periodic CSI-RS pilots for PUCCH periodic feedback, A>=0, and the base station configures a set of periodic or aperiodic CSI-RS pilots for PUSCH aperiodic feedback only for PUSCH aperiodic feedback. , B>=0. The B sets of pilots may all be periodic CSI-RSs, all of which are aperiodic CSI-RS or a mixture of periodic and aperiodic CSI-RS. It is worth noting that A and B cannot be 0 at the same time.

Sub-method 3: The base station configures a set of periodic CSI-RS pilots for PUCCH period feedback, A>=0, and the base station configures B sets of aperiodic CSI-RS pilots for PUSCH aperiodic feedback only for PUSCH aperiodic feedback, B >=0. It is worth noting that A and B cannot be 0 at the same time.

Interference measurement resource information configuration: indicated by the Interference Measurement Resource (IMR) configuration. Indicates the resource location of its time-frequency domain. Generally, a process only needs to configure a set of IMRs. However, for some special cases, such as measuring multiple different inter-user interferences or different interferences on different subframe groups, multiple sets of IMRs can be configured and associated with the same or different channels. Measuring resources.

Method 2: When X is one, different feedback types (PUCCH period feedback and PUSCH aperiodic feedback) of the channel information process of the base station configure interference measurement resources by using different signaling, and there are the following sub-methods:

Sub-method 1: The base station configures A set of interference measurement resources IMR for PUCCH period feedback and PUSCH aperiodic feedback, and the base station also configures B sets of interference measurement resources IMR for PUSCH aperiodic feedback. A and B are integers, which can be different for 1, 2 sets of interference measurement resource configuration signaling, and can be configured using different signaling.

Sub-method 2: The base station configures a set of interference measurement IMR for PUCCH period feedback and PUSCH aperiodic feedback, and associates with periodic CSI-RS measurement resources configured by PUCCH period feedback and PUSCH aperiodic feedback, A>=0, and the base station is also a PUSCH. The aperiodic feedback configures the B sets of interference measurement resources and is associated with the non-periodic pilots configured by the PUSCH feedback.

Channel measurement resource information configuration: The same set of configuration signaling is used to jointly configure the PUCCH period feedback and the PUSCH aperiodic feedback. The base station and the terminal agree that the PUCCH period feedback is not enabled when the aperiodic CSI-RS is configured.

Method 3: When X is multiple, channel measurement resources can be configured in two ways:

Method 1: For each CSI process, the channel measurement resource and the interference measurement resource configuration for different feedback modes are performed by using the method mentioned in the specific implementation methods 1, 2.

Method 2: For the Y CSI processes in X, the channel measurement resources and interference measurement resource configurations for different feedback modes are performed by using the methods mentioned in the specific implementation methods 1, 2. 1<=Y<X; other CSI processes can use each process to configure channel measurement resources and interference measurement resources separately, and no longer distinguish between feedback modes.

Embodiment 2

This embodiment provides an information feedback method, which is applied to a terminal, as shown in FIG. 5, and includes:

Step 51: Determine channel measurement resources and interference measurement resources according to the current feedback type, in combination with configuration signaling of the base station;

Step 52: After performing measurement on the channel measurement resource and the interference measurement resource, and obtaining the quantized CSI information, the feedback type is fed back.

For example, the periodic feedback of the terminal on the PUCCH when the current measurement and feedback. The terminal determines that the current CSI Process Index is i (i=1, 2, 3, 4), then the terminal finds the channel measurement resource and the interference measurement resource corresponding to the periodic feedback CSI Process i on the PUCCH from the base station configuration signaling. And perform CSI measurement and quantization.

The terminal performs CSI feedback on the PUCCH period feedback resource location corresponding to the CSI Process i.

Another example is the periodic feedback on the PUSCH when the terminal currently measures and feeds back. The terminal determines that the current CSI Process Index is j (i=1, 2, 3, 4), then the terminal looks for the base station configuration signaling. The channel measurement resource and the interference measurement resource corresponding to the CSI Process j are periodically fed out on the PUCCH. And perform CSI measurement and quantization.

The terminal performs CSI feedback on the PUSCH aperiodic feedback resource location corresponding to the CSI Process j.

The terminal judges the feedback mode of the current CSI quantization feedback.

For example, the current feedback mode of the terminal is the periodic feedback mode 2-1 on the PUCCH. The terminal determines that the current CSI Process Index is i (i=1, 2, 3, 4), then the terminal finds channel measurement resources and interference measurement corresponding to the periodic feedback mode 2-1 CSI Process i on the PUCCH from the base station configuration signaling. Resources. And perform CSI measurement and quantization.

The terminal performs CSI feedback on the resource location of the PUCCH period feedback mode 2-1 corresponding to the CSI Process i.

For example, the current feedback mode of the terminal is the periodic feedback mode 3-1 on the PUSCH. The terminal determines that the current CSI Process Index is j (i=1, 2, 3, 4), then the terminal finds the channel measurement resource and interference measurement corresponding to the periodic feedback mode 2-1 CSI Process i on the PUCCH from the base station configuration signaling. Resources. And perform CSI measurement and quantization.

The terminal performs CSI feedback on the resource location of the PUSCH aperiodic feedback corresponding to the CSI Process i.

Embodiment 3

In general, the design of the channel information (CSI) process of the related art is as shown in FIG. 6. One CSI process includes channel measurement resource configuration, configuration of interference measurement resources, and some other configurations. The same CSI process is used both for measurement feedback based on precoded pilots and measurement feedback for non-precoded pilots. The same CSI process is used both for measurement feedback based on periodic pilots and measurement feedback for non-periodic pilots. That is to say, the two different CSI-RS types share a set of CSI processes, and use the same channel to measure resource configuration signaling and interference configuration resource signaling. This approach limits flexibility because channel information measurement and quantization feedback differentiation for different types of pilots is relatively large.

Example 2-1:

In the solution described in this embodiment, the CSI Process of the related art is split and split. The CSI process (or subprocess) corresponding to different pilot types is configured independently for at least some of the parameters. The channel measurement and feedback parameter configuration corresponding to the identical CSI process is no longer used, as shown in FIG. 7. Specifically, the base station can further configure M sub-processes for one CSI process, and optionally M is 2 or 4. The base station can perform channel measurement part configuration, interference measurement part configuration, and other configurations for M sub-processes respectively. For 2, it can be:

Subprocess 1 can be applied to periodic pilots, and subprocess 2 can be applied to non-periodic pilots.

Some of the above signaling does not limit the use of completely independent signaling, but some of the signaling uses independent signaling to bring higher flexibility. For example, the difference in CSR can make two sub-processes use different sub-processes respectively. The codebook is fed back and can be applied to different quantization methods.

The difference in Pc can make different sub-processes have different soft control functions for RI.

Different feedback modes can make different sub-processes have different quantization focuses, some have high precision for CQI, and some have high precision for PMI.

Different pilot types allow multiple pilot types to be supported simultaneously in the same Process.

Different CSI reporting classes can enable some sub-processes to be quantized by means of beam selection. Some sub-processes can be quantized by means of direct feature quantization.

The codebook selection indication information may be 4Tx codebook version. The indication information selected may be such that some subProcess adopts the R8 version of the 4Tx codebook and the subProcess uses the R12 version of the 4Tx codebook.

Or the indication information carrying the 0 element codebook and all the non-zero element codebooks respectively adapt to different quantization requirements.

Example 2-2:

As in the example in the embodiment 2-1, different sub-processes sub-process may be applied to the PUCCH feedback mode and the PUSCH feedback mode respectively. In addition, different sub-processes sub-process are applied to the CSI reporting respectively. Class, for example, Class A is bound to subprocess1 in a way that includes port selection, and CSI reporting Class B is bound to subprocess2 in direct quantization mode.

These two methods can be embodied by the difference of the codebook feature. The former is a codebook containing 0 elements in the codeword, and the latter is a codebook not containing 0 elements in the codeword.

Example 2-3:

This embodiment does not necessarily need to define multiple sub processes, but at least one or more parameters in the related art process need to be split into multiple sets of independent configuration parameters, which are respectively applied to different uses.

Class A is a method that includes port selection, and CSI reporting Class B is a direct quantization method. These two methods can be embodied by the difference of the codebook feature. The former is a codebook containing 0 elements in the codeword, and the latter is a codebook not containing 0 elements in the codeword.
