Description

Parameter value determination and configuration method and device, terminal and base station

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for determining and configuring parameter values, a terminal, and a base station.

Background

In a wireless communication system, a transmitting end and a receiving end generally adopt multiple antennas for transmitting and receiving to obtain a higher rate. One principle of the multi-antenna technology is to utilize some characteristics of a channel to form multi-layer transmission matching the characteristics of the channel, the radiation direction of a signal is very targeted, the system performance can be effectively improved, and remarkable performance improvement can be obtained on the basis of not increasing the bandwidth and the power. The performance of data transmission in multi-antenna systems depends mainly on the measurement and feedback of channel information. Therefore, the measurement and feedback of channel information are the core content of the multi-antenna technology; how to guarantee the accuracy, overhead and robustness of channel measurement and channel information feedback becomes an important problem.

Measurement and feedback of Channel State Information (CSI) are designed to be simpler in an early Long Term Evolution (LTE) system version, but as the accuracy requirement is higher and higher, and pilot overhead, feedback overhead and quantization complexity are not expected to increase significantly, the CSI measurement and feedback technology becomes more and more complex to pursue higher quantization efficiency; in addition, because the antenna configuration has better adaptability to various different scenes, a great amount of new designs are introduced. Some basic contents related to CSI measurement and quantization feedback are introduced below:

CSI measurement reference signal

A Channel State Information Reference Signal (CSI-RS) may be used for measurement of downlink Channel Information. CSI-RS are divided into two categories: non-precoded pilot (Non-precoded CSI-RS, NP CSI-RS for short), precoded pilot (Beam Formed CSI-RS, BFed CSI-RS for short). For NP CSI-RS, a base station acquires channel state information by transmitting pilot frequency at all ports, receiving the pilot frequency by a user, measuring and feeding back the channel information. For BFed CSI-RS, a base station configures precoding matrixes for different port groups, the CSI-RS is loaded on the precoding matrixes on K sets of CSI-RS resources to be sent (K is larger than or equal to 1), and a user measures equivalent channels and feeds back the CSI on the best CSI-RS resources.

CSI feedback mode

There are two main ways for feedback of terminal CSI: the base station may configure the terminal to measure and quantize Channel information, and periodically feed back quantized CSI information (CQI, rank Indicator, RI, preceding Matrix Indicator, PMI, for short) through an Uplink Control Channel (PUCCH). The base station can also trigger the terminal to report the CSI information (including RI/PMI/CQI) in an aperiodic way when needed. The problems that the instantaneity of periodic feedback is not high enough and the CSI quantization precision is limited by the overhead of a control channel are solved. In addition, when the terminal calculates the feedback CSI, the CSI calculation and feedback are performed according to the assumption of the transmission mode based on the semi-static configuration of the transmission mode.

CSI two feedback categories:

there are two categories of measurement and feedback of channel information: class a and Class B, respectively. Both categories are semi-statically configured using RRC signaling.

Class A: the base station sends CSI-RS (channel state information-reference signal), which is generally non-precoded pilot frequency, and the user directly carries out channel measurement and CSI quantization based on the CSI-RS pilot frequency to obtain RI/PMI/CQI. The contents are fed back on the PUCCH or PUSCH, and the feedback contents are many, including the beam direction of the wideband.

Class B: the CSI-RS sent by the base station is generally a precoded pilot, and a user may need to select the precoded pilot first and then perform quantization feedback of channel information based on the selected CSI-RS pilot, where the channel information includes CSI-RS resource index (CRI) selection information and RI/PMI/CQI information corresponding to the selected CSI-RS measurement resource subset.

In the related art, the CSI calculation and feedback need to be configured semi-statically according to RRC signaling, which greatly limits the flexibility of CSI feedback and transmission mode selection, and the base station cannot flexibly and dynamically adjust the transmission mode according to CSI, thereby greatly limiting the performance improvement of information transmission. In view of the above problems in the related art, no effective solution exists at present.

It needs to be configured by additional higher layer signaling.

Further, each Set RRC _ RS _ Set in the pilot parameter sets at least includes one of the following parameters and values of the parameters:

The code book Subset restriction CSR is a code book configuration signaling, which may also be referred to as code book Subset Selection, or code book Subset restriction, and refers to restricting a code word set of a UE to a large code book set Subset, so that a code book Subset suitable for the UE or a code book Subset reducing interference to other UEs may be selected according to a channel characteristic of the UE, thereby reducing a code book Selection complexity of the UE and restricting a beam direction of the UE.

To summarize, the CSI feedback related parameter set may include parameters as shown in table 3 below.

Table 3: CSI feedback related parameters

It should be noted that the CSI feedback related parameters are also configured for each user, and in future wireless communication technologies, a multi-layer network may be involved, where each network has multiple base stations, and each base station includes multiple beams. Therefore, the feedback content is very much, and more resources are needed to feed back the parameter information. In order to save resources for reporting the CSI, the CSI feedback related parameters may also be configured into a pool called a CSI feedback pool, where the CSI feedback pool includes configuration of multiple CSI feedback parameters, and multiple users share the CSI feedback pool, and which user is used is determined by the base station or determined by the base station and the user through a protocol agreement.

And (1.2) configuring indexes of the pilot resource parameter sets through physical layer signaling or Media Access Control element (MAC CE) to indicate pilot resource information which needs to be measured by the terminal, and/or configuring CSI feedback parameter set indexes to indicate information related to CSI feedback of the terminal.

The physical layer signaling includes Downlink Control Information, DCI, of LTE or other protocols.

Configuring N0 channel state information feedback related parameter set through high-level signaling: RRC _ CSI _ Set0, \8230, RRC _ CSI _ SetN0-1

The contents of the pilot resource parameter set and the CSI feedback related parameter set are similar to those of the two-layer signaling structure in (1), and are not repeated here.

(2.2) configuring the pilot resource parameter subset and/or the CSI feedback related parameter subset through the MAC CE.

The pilot resource parameter subset of the MAC CE is determined by pilot resource parameter sets RRC _ RS _ Set0, \ 8230, RRC _ RS _ SetM0-1, namely M1 in RRC _ RS _ Set0, \ 8230and RRC _ RS _ SetM 0-1. Can be recorded as MAC _ RS _ Set0, \8230;, MAC _ RS _ SetM1-1. In the MAC CE, only MAC _ RS _ Set0, \8230;, MAC _ RS _ SetM1-1 in RRC _ RS _ Set0, \8230;, RRC _ RS _ SetM0-1 index, can be configured, and the MAC _ RS _ Set0, \8230;, MAC _ RS _ SetM1-1 parameter configuration information can be found through the index.

If aperiodic, the MAC CE also needs to include the activation times of the M1 pilot-related parameter subsets MAC _ RS _ Set0, \ 8230, MAC _ RS _ SetM1-1. In case of Semi persistence, the MAC CE further includes activated or deactivated parameter configuration of M1 pilot related parameter subsets MAC _ RS _ Set0, \8230, MAC _ RS _ SetM1-1.

The CSI feedback related parameter subset of the MAC CE is determined by a CSI feedback related parameter Set RRC _ CSI _ Set0, \8230, RRC _ CSI _ SetN0-1, namely N1 of RRC _ CSI _ Set0, \8230andRRC _ CSI _ SetN 0-1.

If the parameter configuration is Semi persistent, the MAC CE also comprises N1 CSI feedback related parameter subsets MAC _ CSI _ Set0, \8230, MAC _ CSI _ SetN1-1.

Of course, the MAC CE may also include other signaling that needs to be transmitted in the MAC CE.

The terminal receives a pilot resource parameter set configured by RRC, a pilot resource parameter subset configured by MAC CE, and an index of the pilot resource parameter subset configured in DCI signaling. And determining the configuration of the pilot resource parameter subset configured by the MAC CE according to the index information of the DCI, and selecting the pilot resource parameter corresponding to the terminal from the pilot resource parameter set configured by the RRC according to the index in the configuration of the pilot resource parameter subset configured by the MAC CE.

Example eight

This embodiment provides a specific implementation of the channel information feedback parameter configuration in the seventh embodiment. Mainly the codebook subset limits the more detailed design of the CSR and its feedback overhead. As shown in fig. 5a, multiple bit maps are configured in RRC, and one or more bit maps are selected in MAC CE or DCI signaling. The configuration of the CSR parameters will be described in two ways according to the form of the bitmap.

The first method is as follows: the bit map configured in RRC signaling is the bit map of the whole codebook

For example, the antennas are configured in N1 rows and N2 columns, the configured codebook has a first dimension oversampling factor of O1 and a second dimension oversampling factor of O2, and then the first precoding matrix W1 has Nb = N1 × N2 × O1 × O2 total beams, and the beams are arranged, where each beam is represented by one bit, and when the bit represents 0, it represents a beam that the terminal cannot select, and when the bit represents 1, it represents a beam that the terminal can select. This is called the bit map of the W1 codebook, and each represents whether a beam of the Nb beams can be used by Nb bits. Of course, there may also be a bitmap of the second-dimension precoding matrix W2 and bit maps of other codebooks, both of which are used to limit which codebooks can be used and which codebook terminals cannot be used, and the specific concept may refer to the protocol of LTE/LTE a.

In the first embodiment, the bit map includes the entire codebook, for example, W1, and Nb bits are required to represent the bit map.

The RRC configures a CSR parameter set, where each element in the set is a bitmap of the entire codebook, as shown in fig. 5b, such as bitmap 1 of the entire codebook, bitmap 2 of the entire codebook, bitmap 3 of the entire codebook, \ 8230, and bitmap N of the entire codebook, respectively.

The different bit values in different bit maps can achieve the purpose of different code word accuracies in different angle ranges, for example, a higher progress is required in the direction 1, then bits corresponding to all the beams near the direction 1 all take a value of 1, otherwise, only one of the beams can be selected from several beams near the direction to take a value of 1.

In the two-layer signaling configuration mode, the base station only needs to directly indicate the index of the element in the CSR bitmap set of the RRC signaling configuration used by the terminal in the DCI.

The terminal receives the CSR bitmap set configured by the RRC, receives the CSR bitmap set index in the DCI signaling, and finds the value of the CSR bitmap which is configured by the base station and belongs to the terminal in the CSR bitmap set configured by the RRC by using the CSR bitmap set index, so that the terminal can know which beams are limited.

In the case of three-layer signaling, in the MAC layer, the base station needs to further configure a CSR parameter subset through the MAC CE, where the CSR parameter subset includes indexes of elements in one or more RRC-configured bitmap sets. And selects an index of an element in a CSR subset configured in the MAC layer in the DCI.

The terminal receives the CSR bitmap set configured by the RRC, receives the CSR parameter subset configured by the MAC CE, receives the sub-CSR parameter set index in the DCI signaling, finds the value of the sub-CSR parameter set configured by the base station in the sub-CSR parameter set index configured by the MAC CE by using the sub-CSR parameter set index, and obtains the value of the CSR bitmap configured by the RRC according to the value of the sub-CSR parameter set, thereby knowing which beams are limited.

The second method comprises the following steps: configuring 1 CSR bitmap of whole codebook in RRC signaling, and configuring N CSR bitmaps taken from total bitmap

As shown in fig. 5c, the RRC configures a CSR total bitmap of the whole codebook and configures N sub-CSR bitmaps taken from the total bitmap: for example, sub-CSR bit map 1 of Nb1 bits, sub-CSR bit map 2 of nb2 bits, \ 8230, sub-CSR bit map N of NbN bits, where Nb1, nb2, \ 8230, nbN may be different values, i.e., each sub-CSR bit map contains a different number of bits, but may also be the same.

There may be multiple methods of selecting sub-CSR bits from the total CSR bit map, each method may implement different functions

The method comprises the following steps: the purpose that different sub-CSR sets indicate codebooks with different oversampling factors can be achieved, the purpose that oversampling factors in different directions are different is achieved, a codeword corresponding to a total bitmap is 8 times oversampling, a sub-CSR bitmap formed by taking one value from every 8 bits in the total CSR bitmap 1 is achieved by the sub-CSR bitmap, the purpose of 1 time oversampling is achieved, a sub-CSR bitmap formed by taking one value from every 4 bits in the total CSR bitmap 2 is achieved by the sub-CSR bitmap 2, the purpose of 2 times oversampling is achieved, and the purpose of 4 times oversampling is achieved by the sub-CSR bitmap formed by taking one value from every 2 bits in the total CSR bitmap 3. Such a sub-CSR bitmap may be selected for the first precoding matrix W1 of the 1-dimensional codebook, where only the oversampling factor O1 is limited, or for the first precoding matrix W1 of the 2-dimensional codebook, where the oversampling factor includes the first dimension oversampling factor O1 and the first dimension oversampling factor O2, and the sub-CSR bitmap may achieve the purpose of limiting O1 and O2 by selecting different sub-CSR bitmaps from the total CSR bitmap.

The method 2 comprises the following steps: successively taking Nk bits as sub-CSR bitmap

The overall bitmap may be divided into Nb/Nk halves, each half including successive sub-CSR bitmaps of the size of Nkbit.

For example, nk =8, the total bitmap is divided into 8 halves, each half including 8 bits of sub-CSR bitmaps.

And configuring CSR parameter sets in RRC, wherein each CSR parameter set comprises a sub CSR bitmap with Nk bits.

And the terminal can expand or reconstruct or reassign the sub-CSR bitmap in the CSR set indicated by the DCI according to the self channel state information to form a new sub-CSR bitmap. And selecting the beam/code word by using the new sub CSR bitmap. The terminal may also feed back a new sub-CSR bitmap.

In the case of three-layer signaling, in the MAC layer, the base station needs to further configure a CSR parameter subset through a MAC CE, where the CSR parameter subset includes indexes of elements in one or more RRC-configured bitmap sets. And selects an index of an element in a CSR subset configured in the MAC layer in the DCI.

The terminal receives the CSR bitmap set configured by the RRC, receives the CSR parameter subset configured by the MAC CE, receives the sub-CSR parameter set index in the DCI signaling, finds the value of the sub-CSR parameter set configured by the base station in the sub-CSR parameter set index configured by the MAC CE by using the sub-CSR parameter set index, and obtains the value of the sub-CSR bitmap configured by the RRC according to the value of the sub-CSR parameter set, thereby knowing which beams are limited.

Similarly, the terminal may expand or reconstruct or reassign the sub-CSR bitmap in the CSR set indicated by the DCI according to the channel state information of the terminal itself, so as to form a new sub-CSR bitmap. And selecting the beam/code word by using the new sub CSR bitmap. The terminal may also feed back a new sub-CSR bitmap.

The CSR bitmap or sub-CSR bitmap herein is an element in the CSR parameter set, and the CSR parameter subset represents a subset of the CSR parameter set, or an index pointing to the CSR parameter set, or a set of indices.

In addition, the terminal and the base station can achieve the purpose of reducing the overhead of the feedback code word according to the CSR limit. I.e. for example the overhead of the first precoding matrix index i1 and/or the overhead of the second precoding matrix index i2. Wherein the size of the overhead is related to the following parameters:

the CSR parameter set indication information is included in the CSR parameter set indication information,

the CSR parameter subset indication information is indicative of,

CSR parameter indication information.

In release 13 of LTE, a Codebook is designed to include DFT vectors with two dimensions, and the number of codewords is generally large, which increases the overhead of feedback. For the same i11 and i12, when the codebook lookokconfig =1, the i2 codebook only has 4 codewords selected by the co-phase, and when the codebook lookokconfig >1, the i2 includes 16 codewords selected by the co-phase and beam. Wherein i11 and i12 correspond to the first dimension index and the second dimension index of the first precoding matrix, respectively. i2 corresponds to the second precoding matrix index.

However, this requires RRC signaling to configure the value of the CodebookConfig, and here, the content of the CSR bitmap in the CSR parameter set may be constructed, so as to achieve the purpose of selecting the codebook type. For example, the code word that can be used by the terminal limited by the CSR bitmap i in the CSR parameter set is the same as the code word corresponding to the CodebookConfig = i, i =1,2,3,4. Therefore, the purpose of limiting the i2 feedback overhead is achieved by configuring the CSR parameter set, for example, in the CSR bit map 1, only 2-bit phasing needs to be fed back, and when i =2,3,4, i2 needs to be fed back.

Example nine

This embodiment provides a specific implementation of channel information feedback parameter configuration, and mainly relates to configuration of CSI reporting resources.

In this embodiment, the resource for reporting CSI includes a time domain resource for CSI reporting, such as which symbols or subframes to report on, and/or a frequency domain resource for CSI reporting, such as which subcarriers or subcarrier groups, subcarrier sets to report CSI on, and/or a beam for CSI reporting, such as which beam or beams to report CSI on, where the beam mainly refers to a beam of the terminal. In order to achieve the purpose of sharing the CSI reporting resources by a plurality of users, a plurality of CSI reporting resources form a CSI reporting resource pool (pool), K CSI reporting resources in the CSI reporting pool configure CSI _ Config1, CSI _ Config2, \ 8230, and CSI _ Config K. Each CSI reporting resource configuration at least comprises 1 or more combinations of a CSI reporting time domain resource, a CSI reporting frequency domain resource and a CSI reporting beam.

The CSI reporting resource may be applied to periodic CSI reporting, such as reporting CSI periodically in some subframes according to periodicity and subframe offset, but symbols in each subframe may use different beams. It can also be applied to aperiodic CSI reporting.

The base station indicates the CSI reporting resource used by the terminal in the following signaling indication display mode, or implicit modes such as the appointed relation between the two parties or whether the channel is reciprocal or not. Methods include, but are not limited to, the following:

the method I comprises the following steps:

the base station configures CSI reporting resource sets CSI _ Config1, CSI _ Config2, \ 8230and CSI _ Config K through high-level signaling, and indicates the index of the CSI reporting resource set of the terminal through high-level or physical-level signaling in a certain downlink subframe.

The terminal determines a CSI reporting resource set according to the base station signaling, and selects CSI reporting resources from the CSI reporting resource set according to index signaling of the CSI reporting resource set sent by the base station;

the third method comprises the following steps:

the base station and the terminal can determine the first wireless resource for CSI reporting according to the relation by appointing the relation between the CSI reporting time domain resource set and the CSI reporting beam resource.

The terminal determines the beam information reported by the CSI by itself, and determines the time domain resource for reporting the CSI according to the relation between the CSI reported time domain resource set and the beam resource reported by the CSI.

The agreed relationship includes, for example, that the CSI reporting resources of odd subframes are reported by beam 1, and the CSI reporting resources of even subframes are reported by beam 2.

Here, the time domain resource reported by the CSI may also be replaced by a frequency domain resource reported by the CSI, a time domain resource reported by the CSI, and a frequency domain resource reported by the CSI.

The method is as follows:

and the base station configures the CSI reporting time domain resource set through a high-level signaling, and instructs the terminal to select the CSI reporting time domain resource from the CSI reporting time domain resource set through a high-level or physical layer signaling. The base station and the terminal agree on the relation between the time domain resource set and the beam resource reported by the CSI, and the relation is used for the terminal to determine the beam resource reported by the CSI

The terminal determines a CSI reporting time domain resource set according to the base station signaling, selects CSI reporting time domain resources reported by the CSI from the CSI reporting time domain resource set according to the base station signaling, and determines beam information for CSI reporting according to the agreed relation between the CSI reporting time domain resource set and the beam resources;

Here, the time domain resource reported by the CSI may also be replaced by a frequency domain resource reported by the CSI, a time domain resource reported by the CSI, and a frequency domain resource reported by the CSI

The fifth mode is as follows:

the base station configures a time domain resource set reported by the CSI through a high-level signaling, appoints a relation or a relation set of the time domain resource reported by the CSI and a wave beam resource, and instructs a terminal to select the CSI reporting resource from the relation or the relation set in the high-level or physical-layer signaling.

The terminal determines a CSI reported time domain resource set and the relation or the relation set of the CSI reported time domain resource and a wave beam according to the base station signaling, and selects the CSI reported time domain resource from the set according to the base station signaling;

the agreed relationship here includes, for example, that the CSI reporting resources of odd subframes are reported by beam 1 and the CSI reporting resources of even subframes are reported by beam 2.

The relation set comprises more than one relation, and a subset in the relation set or an element index of the relation set needs to be further configured in the MAC CE, and the relation subset index is further indicated through physical layer signaling.

The terminal needs to obtain the index of the relation subset according to the physical layer signaling, and find the relation in the relation set configured by the high layer signaling according to the relation of the index of the relation in the sub-relation set or the index in the sub-relation set received by the MAC CE.

The method six:

the base station configures a wave beam resource set reported by the CSI through a high-level signaling, indicates a user to select a wave beam resource reported by the CSI from the wave beam resource set through a high-level or physical-layer signaling, and appoints a relation between a time domain resource reported by the CSI and the wave beam resource with the terminal.

The terminal determines a wave beam resource set reported by the CSI according to the base station signaling, selects a wave beam reported by the CSI from the wave beam resource set according to the base station signaling, and determines a time domain resource used for reporting the CSI according to the appointed relation between the time domain resource set reported by the CSI and the wave beam resource;

The seventh mode comprises the following steps:

the base station determines a wave beam resource set reported by the CSI through a high-level signaling, and appoints the relation between a CSI reported time domain resource and the wave beam resource or the relation set, and the base station indicates the terminal to select the CSI reported time domain resource from the relation or the relation set through the high-level or physical layer signaling.

And determining the frequency domain resource reported by the CSI according to the relation between the time domain resource reported by the CSI and the beam resource, or the relation set and the time domain resource reported by the CSI.

It should be noted that, in the method of this embodiment, if the same terminal is configured with multiple CSI reporting resources, such as multiple TTIs in the time domain, multiple subcarrier sets in the frequency domain, or multiple beam resources in the spatial domain, the content reported by the terminal may be the same in the CSI reporting resources, so that the base station may obtain more robust CSI reporting resources.

Example ten

This embodiment provides a specific implementation of pilot resource allocation. Mainly the problem of the configuration of a plurality of pilot frequency resource pools.

For simplicity of description, the pilot resource pool herein takes CSI-RS pilot resource pool CSI-RS pool as an example, and the pilot resource pools of other pilots such as CRS, SRS, DMRS are similar.

In order to share several sets of pilot frequencies by multiple users, the base station configures one CSI-RS pool, wherein the CSI-RS pool comprises M sets of CSI-RS pilot frequency resources, and each set of CSI-RS pilot frequency resource comprises a pattern of the pilot frequency, the port number of the pilot frequency, the time domain characteristic and the frequency domain characteristic of the pilot frequency and the like. The base station may designate a group of users to share the set of pilot resource pools. And indicating which one or more CSI-RS resources in the CSI-RS pool are used by the user to measure the channel state information through a signaling display indication mode or an agreed relationship or a binding relationship.

Optionally, the base station may configure more than 1 set of CSI-RS pool, thereby achieving more flexible configuration of CSI-RS resources. Here, N sets of CSI-RS POOL are used as columns, such as CSIRS _ POOL1, \8230, CSIRS _ POOLN

The base station needs to indicate the CSI-RS pool that the user needs to measure explicitly or implicitly. The terminal obtains the information of the CSI-RS pool according to the signaling notification displayed by the base station or the implicit binding or agreed relationship, and the CSI-RS pool determines the measurement of 1 or more CSI-RS resource users CSI according to the signaling displayed by the base station or the implicit signaling.

And CSI-RS resource indication information CRI, wherein the value of each CRI corresponds to one CSI-RS resource and also implicitly corresponds to one beam. Because the CSI-RS configured by the base station may be transmitted after being precoded by one beam.

For the case of N CSI-RS spots, each resource pool has a CRI corresponding/associated, bound to it. Or N CRIs, each corresponding to/associated with and bound to one CSI-RS pool.

The CSI-RS pool parameters further include time domain parameters, such as subframe index, subframe offset, slot index, symbol index, and frame index. The index here may also be a number.

When the CSI-RS is non-periodically configured or triggered/activated by physical layer signaling, the terminal will ignore the time domain parameter configuration.

The terminal and the base station respectively feed back and receive the CRI and the CSI-RS pool in the following way.

The first method is as follows: manner of displaying signaling

The terminal feeds back N pilot frequency resource indication information and a pilot frequency resource set corresponding to the N pilot frequency resource indication information;

a base station receives N CRIs fed back by a terminal and receives pilot frequency resource sets corresponding to the N CRIs;

the second method comprises the following steps: implicit commitment or binding relationships

And the base station and the terminal appoint to report the CRI resource and the pilot frequency resource set. The CRI reporting resource comprises at least one of a time domain resource, a frequency domain resource and a beam for reporting the CRI.

And the base station determines a pilot frequency resource set according to the CRI resource reported by the terminal and obtains the CRI value according to the value carried on the CRI resource reported by the terminal.

The third method comprises the following steps: base station configuration binding relationship

And the base station configures the relation between the CRI reporting resource and the pilot frequency resource set. The CRI reporting resource comprises at least one of a time domain resource, a frequency domain resource and a beam for reporting the CRI.

The base station determines a pilot frequency resource set according to the CRI resource reported by the terminal and the relationship between the CRI resource configured by the base station and the pilot frequency resource set, and obtains the CRI value according to the value carried on the CRI resource reported.

After determining the set of pilot resources, the terminal needs to further determine the pilot resources and/or the subset of pilot resources in the set of used pilot resources. Wherein the subset of pilot resources comprises one or more pilot resources, but is generally less than the number of pilot resources in the set of pilot resources. The base station and the terminal configure or receive the pilot resource/subset of pilot resources in one of the following ways.

The first method is as follows: signaling configuration

A base station configures a pilot frequency resource set through a high-level signaling, and configures an index or an index set of the pilot frequency resource corresponding to a current user through a high-level or physical-level signaling;

the terminal receives the index or index set of the pilot frequency resource configured by the base station, and selects the pilot frequency resource or the pilot frequency resource subset in the pilot frequency resource set according to the index or index set of the pilot frequency resource.

The second method comprises the following steps: binding or commitment relationships

The resources occupied by the pilot resource/pilot resource subset signaling comprise at least one of time domain resources, frequency domain resources and beams for transmitting the pilot resource/pilot resource subset.

And the terminal determines the pilot frequency resource/pilot frequency resource subset through the resource occupied by the pilot frequency resource/pilot frequency resource subset signaling.

The third method comprises the following steps: binding or commitment relation of base station configuration

The base station configures the relation or binding relation between the resources occupied by the pilot resource/pilot resource subset signaling and the pilot resource set. The resources occupied by the pilot resource/pilot resource subset signaling comprise at least one of time domain resources, frequency domain resources and beams for transmitting the pilot resource/pilot resource subset.

The terminal receives the relation or binding relation between the resource occupied by the pilot resource/pilot resource subset signaling configured by the base station and the pilot resource set, and the terminal determines the pilot resource/pilot resource subset according to the resource occupied by the pilot resource/pilot resource subset signaling and the affiliated relation.

EXAMPLE eleven

This embodiment provides a specific implementation of pilot resource allocation.

Rate matching correlation means. The configuration parameter may be a zero power CSI-RS resource, a non-zero power CSI-RS resource, or a PQI. Taking the configuration example of the zero-power CSI-RS resource, the conventional way is to configure the zero-power CSI-RS through a bitmap to inform the terminal which positions do not receive data. The method of the present invention is to perform zero power CSI-RS indication in an agreed manner, for example, according to a sequence from front to back, for example, ZP CSI-RS resources in 16 states originally require a bit map of 16 bits, and may be used to configure the zero power CSI-RS according to the first 4 states agreed by the base station and the terminal, so that signaling may be reduced to 4 bits, or the middle continuous 4 states are used to configure the zero power CSI-RS, or the following continuous 4 states are used to configure the zero power CSI-RS, or any other agreed 4 continuous states are used to configure the zero power CSI-RS, or are not used to configure the zero power CSI-RS. The drawback is that the configuration of the actual CSI-RS will be limited. The specific provisioning mode may be extended.
