Information reporting method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for reporting information.

Background

The spectrum sharing among different communication systems is effective authorization for solving the contradiction between the supply and the demand of resources caused by the traditional spectrum using mode, so that the spectrum resources are fully utilized. For example, spectrum sharing can be achieved between a New Radio (NR) communication system and a Long Term Evolution (LTE) communication system, and for example, both NR and LTE can be deployed on frequency domain resources such as 2.1 gigahertz (GHz) (band 1), 1.8GHz (band 3), 800 megahertz (MHz) (band 3), and 2.6GHz (band 38).

In order to adapt to the change of the wireless channel, the terminal needs to report the channel state information for the network device to refer to. How to report accurate channel state information under the scene of spectrum sharing of different communication systems is an urgent problem to be solved.

The chip system may include a chip and may also include other discrete devices.

2. A network device. In the embodiment of the present application, the network device is a device that provides a wireless communication function for the terminal device, and may also be referred to as an access network device, a Radio Access Network (RAN) device, and the like. Therein, the network device may support at least one wireless communication technology, such as LTE, NR, WCDMA, etc. Exemplary network devices include, but are not limited to: a next generation base station (generation node B, gNB), evolved node B (eNB), radio Network Controller (RNC), node B (NB), base Station Controller (BSC), base Transceiver Station (BTS), home base station (e.g., home evolved node B or home node B, HNB), base Band Unit (BBU), transceiving point (TRP), transmitting Point (TP), mobile switching center, etc., in a fifth generation mobile communication system (5 th-generation, 5G).

By way of example, a system of chips may include a chip and may also include other discrete devices.

3. Communication between a terminal device and a network device. In the embodiment of the application, the terminal device and the network device communicate through the communication interface. For example, the communication interface between the terminal device and the network device may be a universal UE to network interface (Uu air interface). When the communication interface between the terminal device and the network device is a Uu air interface, the communication between the terminal device and the network device may also be referred to as Uu air interface communication.

4. A time unit. A time unit in the embodiments of the present application may refer to a period of time in the time domain. In the embodiment of the present application, a time unit may include one or more basic time units. Specifically, in this embodiment, communication such as sidelink communication or Uu air interface communication is performed in units of basic time units. For example, the basic time unit may be a radio frame (radio frame), a subframe (subframe), a slot (slot), a micro-slot (micro-slot), a mini-slot (mini-slot), or a symbol, etc. For example, a basic time unit is a subframe, and one time unit may include one or more subframes; as another example, a basic time cell is a symbol, and a time cell may include one or more symbols. In some embodiments, the duration of one radio frame may be 10 milliseconds (ms). One radio frame may include one or more subframes. For example, if the duration of one subframe is 1ms, one radio frame may include 10 subframes. One subframe may include one or more slots. The duration of one time slot is related to the size of the subcarrier interval, and the durations of the time slots corresponding to the subcarrier intervals with different sizes are different. For example, when the subcarrier spacing is 15kHz, the duration of one timeslot may be 1ms; the duration of one slot may be 0.5ms when the subcarrier spacing is 30 kHz. For example, a slot in the embodiment of the present application may include one or more symbols. For example, under a normal (normal) Cyclic Prefix (CP), a slot may include 14 symbols; under extended (extended) CP, one slot may include 12 symbols. It should be understood that the symbols in the embodiments of the present application may also be referred to as time domain symbols, for example, the symbols may be Orthogonal Frequency Division Multiplexing (OFDM) symbols, or may also be DFT-s-OFDM (discrete fourier transform spread orthogonal frequency division multiplexing) symbols based on discrete fourier transform spreading, and the like. A minislot (or mini-slot) in the embodiments of the present application may be a unit smaller than a slot, and one minislot may include one or more symbols. For example, a micro-slot (or mini-slot) may include 2 symbols, 4 symbols, or 7 symbols, etc. One subframe may include one or more minislots. A slot may include one or more minislots (or mini-slots).

Taking the subcarrier spacing as 15kHz as an example, the structure of a radio frame in the embodiment of the present application may be as shown in fig. 1, where the duration of the radio frame is 10ms and includes 10 subframes. The duration of each subframe is 1ms. Wherein each subframe comprises 14 symbols. For example, mini-slot 1 includes symbol 0, symbol 1, symbol 2, and symbol 3. As another example, mini-slot 2 includes symbol 2 and symbol 3. As another example, mini-slot 3 includes symbol 7, symbol 8, symbol 9, symbol 10, symbol 11, and symbol 12.

5. A carrier bandwidth portion. The bandwidth portion of the carrier in the embodiment of the present application may be referred to as a bandwidth portion (BWP) for short, and refers to a continuous or discontinuous segment of frequency domain resources on the carrier, where the bandwidth of the continuous or discontinuous segment of frequency domain resources does not exceed the bandwidth capability of the terminal device, i.e. the bandwidth of the BWP is less than or equal to the maximum bandwidth supported by the terminal device. Taking BWP as an example of a segment of continuous frequency domain resource on a carrier, BWP may be a group of continuous Resource Blocks (RBs) on the carrier, or BWP may be a group of continuous subcarriers on the carrier, or BWP may be a group of continuous Resource Blocks (RBGs) on the carrier, etc. One RBG includes at least one RB, for example, 1, 2, 4, 6, or 8, and one RB may include at least one subcarrier, for example, 12. In the embodiment of the present application, the BWP used for the terminal device to communicate with the network device is configured by the network device. For a terminal device, the network device may configure one or more BWPs within one carrier for the terminal device. For example, as shown in a in fig. 2, the network device configures a BWP in a carrier for the terminal device. Wherein the bandwidth of the BWP does not exceed the bandwidth capability of the terminal device, and the bandwidth of the BWP is not greater than the carrier bandwidth. For another example, as shown in b in fig. 2, the network device configures two BWPs, respectively BWP1 and BWP2, within one carrier for the terminal device, where BWP1 and BWP2 overlap. For another example, as shown in c in fig. 2, the network device configures two BWPs, respectively BWP1 and BWP2, within one carrier for the terminal device, where BWP1 and BWP2 are not overlapped at all. It should be noted that, in the embodiment of the present application, the number of BWPs configured by the network device for the terminal device is not limited. Taking version 15 of NR (release 15, rel-15) as an example, the network device can configure 4 BWPs for the terminal device at most. For another example, in a Frequency Division Duplex (FDD) scenario, the network device may configure 4 BWPs for uplink and downlink communications of the terminal device respectively. For another example, in a Time Division Duplex (TDD) scenario, the network device may configure 4 BWPs for uplink and downlink communications of the terminal device, for example, center frequency bands of BWPs with the same number are aligned. Further, the network device may configure the system parameters for the terminal device for each BWP. The system parameters may be referred to as configuration parameters (numerology). The system parameters may include subcarrier spacing, CP type, and/or the like, for example. The CP type may include an extended CP and a normal CP, among others. In the embodiment of the present application, the system parameters corresponding to different BWPs may be the same or different. Taking fig. 2b as an example, the system parameters corresponding to BWP1 and BWP2 may be the same or different. In other embodiments, the network device does not limit other configurations (e.g. BWP locations) for the terminal device for each BWP. In actual communication, after accessing a cell, the terminal device may activate a BWP to communicate with the network device. Typically, BWPs are defined on a given carrier, i.e. a BWP is located within a carrier. Of course, the present application does not limit other definitions for BWP, or other BWP activation schemes, etc.

6. And (4) resources. In the embodiment of the present application, a resource may also be referred to as a time-frequency resource, which is used for transmitting various signals or data and may be represented by a resource grid. FIG. 3 is an exemplary diagram of a resource grid. In the resource grid, a Resource Element (RE) is a resource unit for data transmission or a resource unit for resource mapping of data to be transmitted. One RE corresponds to one symbol in the time domain, e.g., an OFDM symbol or DFT-s-OFDM symbol, and one subcarrier in the frequency domain. One RE may be used to map one complex symbol, for example, a complex symbol obtained through modulation or a complex symbol obtained through precoding, which is not limited in this application. In the frequency domain, RBs may be defined in a resource grid, and a positive integer number of subcarriers, e.g., 12, may be included in one RB in the frequency domain. Further, the definition of RB may also be extended to the time domain, for example, one RB includes a positive integer number of subcarriers and the time domain includes a positive integer number of symbols, for example, one RB is a time-frequency resource block in which the frequency domain includes 12 subcarriers and the time domain includes 7 symbols. A positive integer number of RBs may be included in the resource grid. A slot (slot) may be defined in a resource grid or in a time domain of a time-frequency resource, and as mentioned above, a slot may include a positive integer number of symbols, for example, 14 symbols, etc.

7. Frequency domain resources. In the embodiment of the present application, a frequency domain resource refers to a section of region or range on a frequency domain, and is a representation of a resource in a frequency domain dimension. For example, a positive integer number of subcarriers, such as 12, may be included in one RB in the frequency domain, as represented by the resource grid. For example, the frequency domain resources may also be referred to as carriers, frequency domain regions, frequency bands, or frequency bands, etc. For another example, the frequency domain resource may be 5MHz, 10MHz, 50MHz, or the like.

As an example of spectrum sharing between different communication systems, table 1 and table 2 show some available frequency bands in the current LTE communication system and NR communication system, respectively:

table 1: available frequency band for LTE

Table 2: usable frequency band with NR below 6GHz (sub 6 GHz)

As shown in tables 1 and 2, spectrum sharing between the LTE communication system and the NR communication system is supported in

band

1, 3, 5, etc., that is, the LTE communication system and the NR communication system may be deployed in an overlapping manner in these frequency band ranges.

When the NR communication system and the LTE communication system share spectrum resources, the carrier of the NR communication system not only fully utilizes resources of the LTE communication system that are not used up, but also avoids interference with transmission on the carrier of the LTE communication system. For example, as shown in fig. 4, assuming that a Physical Downlink Control Channel (PDCCH) of the LTE communication system is mapped on

symbols

0 and 1 on a segment of resources as shown in the figure, a Physical Downlink Shared Channel (PDSCH) of the NR communication system may be mapped from symbol 2, as shown in a gray grid of fig. 4, on which the PDSCH of the NR communication system is mapped. This avoids interference with the PDCCH of the LTE communication system. Meanwhile, in order to avoid interference with a cell-specific reference signal (CRS) transmitted in the LTE communication system, the NR communication system also supports rate matching on resources to which the CRS of the LTE communication system is mapped, that is, assuming that a horizontal stripe lattice represents resources to which the CRS of the LTE communication system is mapped as shown in fig. 4, on these resources, the NR communication system will not map the PDSCH of the NR communication system.

For different communication systems, in order to enable a network side to better know the variation condition of a wireless channel, a terminal device needs to report information related to channel quality to a network device in the communication system. Thus, the network device can select a more reliable Modulation and Coding Scheme (MCS), a better transmission resource, and the like for the terminal device accordingly. The quality-related information may be Channel State Information (CSI), which includes, but is not limited to, a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Precoding Type Indicator (PTI), and a Rank Indicator (RI). As an implementation, the terminal device may measure a channel state information-reference signal (CSI-RS) sent by the network device to obtain the CSI.

In an LTE communication system, the position of a resource mapped by CSI-RS sent by network equipment is related to the number of ports of the CSI-RS and the configuration of the CSI-RS. As shown in fig. 5a, when the number of ports is 1 or 2 (for example, CSI-RS is transmitted through ports 15 and/or 16), there are 32 possible resource locations mapped by CSI-RS, which correspond to gray and numbered REs, respectively, where the number in the REs is from 0 to 31; as shown in fig. 5b, when the number of ports is 4 (for example, CSI-RS is transmitted through

ports

15, 16, 17, and 18), there are 16 possible locations of the CSI-RS map, where

ports

15 and 16 are shaded in gray and there are digital REs, and

ports

17 and 18 are shaded in diagonal lines and there are digital REs. Wherein the numbers in RE include 0-9 and 20-25; as shown in fig. 5c, when the number of ports is 8 (for example, CSI-RS is transmitted through

ports

15, 16, 17, 18, 19, 20, 21, and 22), the CSI-RS mapping positions are 8 kinds of possible, where

ports

15 and 16 are shaded in gray and have RE with numbers,

ports

17 and 18 are shaded in diagonal and have RE with numbers,

ports

19 and 20 are shaded in vertical and have RE with numbers,

ports

21 and 22 are shaded in horizontal and have RE with numbers, and the numbers in the RE include 0 to 5 and 20 to 22. Here, it is assumed that one port maps only 1 RE on 1 RB. In the time domain, the resource location of CSI-RS mapping in an LTE communication system is a minimum repetition unit of one subframe. All numbered parts of fig. 5a (fig. 5b or fig. 5 c) constitute the CSI-RS candidate resource set, on the basis of which the network device may indicate the actual mapping position of the CSI-RS through signaling.

In the NR communication system, the CSI-RS mapped resource location is more flexible than that of the LTE communication system, and there may be a plurality of mapping patterns (patterns). For example, as shown in fig. 6a, pattern1 indicates RE numbers #0, #4, and #8 to which CSI-RSs transmitted through 1 port are mapped on one symbol. Of course, the RE numbers that the CSI-RS transmitted through the port can also map to on a symbol are #1, #5, #9, #2, #6, #10, or #3, #7, #11, and it should be noted that in a subframe, the symbol may be any one of symbols #0 to # 13. As shown in fig. 6b, pattern2 indicates that the RE number to which the CSI-RS transmitted through 1 port is mapped on one symbol is #0, but the CSI-RS transmitted through the port may be mapped on one symbol to any one of REs #1 to # 11. Fig. 6c to fig. 6r may be analogized in turn, and it should be noted that the lowest number in each of fig. 6a to fig. 6r represents the port number, the highest number in each of the figures represents the pattern number, one lattice represents one RE, that is, one symbol in the time domain corresponds to one subcarrier in the frequency domain. The RE framed by one box (fig. 6a frames three boxes, which are considered as a whole) is a basic unit for indicating to the terminal device, and all the mapped REs in a pattern are indicated to the same terminal device. The REs mapped in the same manner belong to the same Code Division Multiplexing (CDM) group, and the REs mapped in different manners belong to different CDM groups. At least 2 symbol positions need to be configured in the

patterns

13, 14, 16, 17, wherein the position of the first symbol (symbol 1) in the first two-symbol continuum can be used to indicate the time domain position of the first two-symbol continuum, and the position of the first symbol (symbol 2) in the second two-symbol continuum can be used to indicate the time domain position of the second two-symbol continuum. In the time domain, the minimum repetition unit of the resource location mapped by the NR communication system CSI-RS is 1 symbol, 2 symbols, or 4 symbols. One or more patterns among the patterns in 18 of fig. 6 a-6 r may constitute the CSI-RS resource set of the terminal device.

Under the scene that the CSI-RS of the NR communication system and the PDSCH of the LTE communication system can be mapped on the same resource, when the frequency spectrum efficiency of the PDSCH of the LTE communication system is not high, on partial resources, when the PDSCH of the LTE communication system is interfered by the CSI-RS of the NR communication system, the terminal equipment of the LTE communication system can still correctly demodulate the content in the PDSCH; however, the CSI-RS of the NR communication system is interfered by the PDSCH of the LTE communication system, which may cause that the CSI reported by the terminal device of the NR communication system is worse than the actual CSI, so that the scheduling decision of the base station of the NR communication system is conservative, thereby causing the throughput of the terminal device of the NR communication system to decrease, and further reducing the efficiency of the entire NR communication system.

The first embodiment is as follows:

in order to solve the above technical problems in the prior art, an embodiment of the present application provides an information reporting method, which can be applied in a scenario where two different communication systems share a frequency spectrum, and is as shown in fig. 7:

step 701: the terminal equipment receives first configuration information from network equipment, wherein the first configuration information is used for determining a coincidence area of a first frequency domain resource of a first communication system and a second frequency domain resource of a second communication system.

Step 702: the terminal device reports Channel State Information (CSI) of the first communication system on the first frequency domain resource to the network device, wherein the CSI reporting mode comprises that: reporting the CSI obtained by the terminal based on the first frequency domain resource except the overlapping area and the CSI obtained by the terminal based on the overlapping area, reporting the CSI obtained by the terminal based on the first frequency domain resource and the CSI obtained by the terminal based on the overlapping area, or reporting the CSI obtained by the terminal based on the first frequency domain resource except the overlapping area.

The terminal device in the embodiment of the present application is a terminal device located in a first communication system, and the network device is a network device supporting the first communication system. Illustratively, the terminal device may access the first communication system through the network device to obtain a service provided by the first communication system. As shown in fig. 8, a network architecture of the first communication system is included.

As described in the beginning of the embodiments, the first communication system and the second communication system described in the embodiments of the present application may be an NR communication system and an LTE communication system, respectively, and hereinafter, the embodiment of fig. 7 is described by taking as an example that the first communication system and the second communication system may be an NR communication system and an LTE communication system, respectively, but it should be noted that the first communication system and the second communication system may be any communication system mentioned above or any communication system evolved later, respectively, as long as the first communication system and the second communication system are not the same communication system, and the present application is not limited in any way.

The first configuration information in step 701 may specifically include configuration information of a carrier of the LTE communication system, where the configuration information of the carrier of the LTE communication system may include one or more of a subcarrier position in a center of the carrier of the LTE system and a bandwidth of the carrier of the LTE communication system. Thus, the terminal equipment can acquire the position information of the second frequency domain resource in the LTE communication system. As an implementation manner, the terminal device may acquire, by the network device, the bandwidth size and/or the location of the active BWP in the NR communication system, that is, the communication system to which the terminal device accesses, so that the terminal device may acquire the location information of the first frequency domain resource in the NR communication system.

Based on the above assumptions, the first frequency domain resource of the first communication system may be understood as an active BWP of the NR communication system; the second frequency domain resource of the second communication system may be understood as a carrier of the LTE communication system.

Based on step 701, the terminal device can determine the overlapping area of the NR communication system and the LTE communication system in the frequency domain. Illustratively, the bandwidth of active BWP of the NR communication system is a continuous frequency domain range, and is 50mhz, the bandwidth of the carrier of the lte communication system is 20MHz, and fig. 9a, 9b or 9c are examples of the coincidence manner of the two. Of the three superposition modes, the superposition bandwidth of fig. 9a and 9b is 20MHz, and fig. 9c is less than 20MHz. That is, the terminal device can also know that, in the current communication, the NR communication system and the LTE communication system are in a spectrum sharing scenario.

In order to overcome the technical defects in the prior art, a new method is needed to report CSI in the NR communication system. In the embodiment of the present application, a modification is made to a reporting manner of CSI of a first frequency domain resource of a first communication system, and compared with the prior art, in which a terminal device reports CSI, which is obtained based on a whole first frequency domain resource, that is, an active BWP of an NR communication system, as CSI of the NR communication system on an active bandwidth, in step 702, the terminal device reports CSI, which is obtained based on one of the following manners, as CSI of the NR communication system on the active BWP:

the first method is as follows: and reporting the CSI obtained by the terminal equipment based on the first frequency domain resource except the overlapping area.

Further explanation is given by taking fig. 9a as an example: as shown in fig. 9a, if the overlap area is 20MHz bandwidth, the terminal device will only measure CSI-RS resources on 30MHz bandwidth (i.e. the portion of the first frequency domain resource excluding the overlap area) except for the overlap area on the active BWP (i.e. the first frequency domain resource) of the NR communication system with 50MHz, and report CSI obtained based on the area measurement to the network device.

The reporting mode avoids the influence of the possibly inaccurate measurement on the overlapped area on the measurement result on the active BWP of the whole NR communication system, and the channel quality information obtained by the network equipment is more accurate.

The second method comprises the following steps: and reporting the CSI obtained by the terminal equipment based on the first frequency domain resource except the overlapping area and the CSI obtained by the terminal equipment based on the overlapping area.

Still taking fig. 9a as an example, the difference between the second mode and the first mode is that, on the active BWP (i.e. the first frequency domain resource) of the NR communication system with 50MHz, the terminal device needs to perform measurement not only on the CSI-RS resources on the bandwidth with 30MHz except the overlapping area (i.e. the part of the first frequency domain resource except the overlapping area), but also on the CSI-RS resources on the bandwidth with 20MHz of the overlapping area. Wherein the two measurements are independent of each other. And the terminal equipment respectively obtains the CSI based on the two areas and reports the CSI to the network equipment.

In this reporting manner, the network device obtains the CSI based on the first frequency domain resource excluding the overlapping region and the CSI obtained based on the overlapping region, and compared with the first manner, the network device further obtains the CSI of the overlapping region as a reference, so that the CSI in the first frequency domain resource range is more comprehensive, and the network device can optimize the manner of scheduling the terminal device based on this, such as selecting a more reliable MCS, a more optimal transmission resource, and the like, so as to improve the throughput of the terminal device and the efficiency of the entire communication system.

The third method comprises the following steps: and reporting the CSI obtained by the terminal equipment based on the first frequency domain resource and the CSI obtained by the terminal equipment based on the overlapping area.

Still taking fig. 9a as an example, in the third mode, as an alternative, the terminal device needs to measure, on the active BWP (i.e. the first frequency domain resource) of the NR communication system with 50MHz, the CSI-RS resource on the active BWP with 50MHz, and also needs to measure the CSI-RS mapped in the CSI-RS resource on the 20MHz bandwidth of the overlapped area. Wherein the two measurements are independent of each other. And the terminal equipment respectively obtains CSI based on the two areas and reports the CSI to the network equipment.

In this reporting manner, the network device obtains the CSI based on the first frequency domain resource and the overlapping area, so that the information related to the channel quality obtained by the network device is comprehensive, and the network device may optimize the manner of scheduling the terminal device based on this, for example, select a more reliable MCS, a more optimal transmission resource, and the like, so as to improve the throughput of the terminal device and the efficiency of the entire communication system.

As an implementation manner, the network device may send second configuration information to the terminal device, where the second configuration information may be CSI configuration information, and is used for the terminal device to determine a reporting format (format) of CSI. The reporting format includes wideband reporting (wideband reporting) or sub-band reporting (sub-band reporting). When the broadband report is configured, the CSI is obtained by measuring the frequency domain resource which is wholly configured for the terminal equipment; when the sub-band reporting is configured, the CSI is obtained by measuring the sub-region (sub-band) of the frequency domain resource configured for the terminal device, and the number of the obtained CSI is multiple.

It should be noted that, when the reporting format is broadband reporting, the three reporting modes described above can be applied. And when the reporting format is sub-band reporting, only the second mode can be applied.

As an implementation manner, the network device may send first indication information to the terminal device, where the first indication information plays a role in enabling, and indicates whether the terminal device adopts one of the above three manners to report the CSI. Optionally, the first indication information may be included in Downlink Control Information (DCI) and indicated by one bit. The DCI may be a terminal device-level (UE-level) DCI or a group-level (group) DCI.

The network device and the terminal device may report in which of the three reporting modes is adopted by the terminal device under the condition that the NR communication system and the LTE communication system have a coincidence region by a protocol agreement. Of course, when there is an overlapping area between the NR communication system and the LTE communication system, the network device may also instruct the terminal device to report in any of the above three reporting methods through the second indication information. The second indication information may also be carried in DCI. The dynamic indication mode is more flexible than the protocol convention mode.

As one implementation, the CSI includes at least one of CQI, PMI, PTI, and RI.

As another implementation, the CSI may be carried on a Physical Uplink Shared Channel (PUSCH) or a Physical Uplink Control Channel (PUCCH).

According to the technical scheme of the first embodiment of the application, one of three newly designed CSI reporting modes is adopted, so that compared with the prior art in which a CSI reporting mode based on the whole first frequency domain resource is reported independently, the channel quality condition in the first communication system can be reflected more accurately, and the loss of throughput and communication efficiency in the first communication system is avoided.

Example two

The embodiment of the present application further provides another method for reporting information, as shown in fig. 10, which can also overcome the above-mentioned technical problem, and an application scenario of the method is similar to that of the network architecture embodiment.

Step 1001: the method comprises the steps that terminal equipment receives first configuration information from network equipment, wherein the first configuration information is used for the terminal equipment to determine that a first frequency domain resource of a first communication system and a second frequency domain resource of a second communication system have a superposition area;

step 1002: and the terminal equipment reports the Channel State Information (CSI) of the first communication system on the first frequency domain resource to the network equipment through measurement of a CSI-RS resource set on the first frequency domain resource, wherein the CSI-RS resource set of the first communication system is a subset of a CSI-RS candidate resource set of the second communication system on the first frequency domain resource.

Similarly to the embodiment, the terminal device in the embodiment of the present application is a terminal device located in the first communication system, and the network device is a network device supporting the first communication system. Illustratively, the terminal device may access the first communication system through the network device to obtain the service provided by the first communication system. The network architecture can refer to fig. 8.

Also, the first communication system and the second communication system may be an NR communication system and an LTE communication system, respectively, for example, but there is no limitation to the first communication system and the second communication system.

The specific content of the first configuration information in step 1001 may be the same as or similar to the first configuration information in step 701 of the embodiment, and is not described herein again.

As an implementation manner, the terminal device may acquire the bandwidth size and/or the location of the BWP activated in the NR communication system, that is, the communication system to which the terminal device accesses through the network device.

Based on the first configuration information, the terminal device may determine that there is a coincidence region in the frequency domain of carriers of the NR communication system active BWP and LTE communication systems. That is, the terminal device can know that, in the current communication, the NR communication system and the LTE communication system are in a spectrum sharing scenario.

Optionally, the terminal device may further determine a coincidence area of the NR communication system and the LTE communication system based on the first configuration information. For a specific determination, see the detailed description of step 701.

When reporting CSI on active BWP of the NR communication system, in this embodiment, interference that may be caused by PDSCH in the LTE communication system to CSI measurement in the NR communication system is avoided by specifying the location of the CSI-RS resource in the NR communication system from the perspective of the CSI-RS resource, compared with the technical solution of modifying the reporting manner in the first embodiment.

In step 1002, the terminal device may still report the CSI on the active BWP of the NR communication system in the same reporting manner as in the prior art. The reporting format can be broadband reporting or narrowband reporting. In contrast to the prior art, provision is made here for: on active BWP of the NR communication system, the set of CSI-RS resources of the NR communication system is a subset of the set of CSI-RS candidate resources of the LTE communication system.

In particular, the CSI-RS candidate resource set in the LTE communication system may be understood as being composed of REs with numbers in fig. 5a (or 5b, or 5 c). However, as mentioned above, the CSI-RS resource set in the NR communication system is more flexible, and there are multiple mapping patterns. That is, the second embodiment requires that the CSI-RS resource set corresponding to the mapping pattern of the NR communication system that the terminal device expects to receive needs to overlap with the CSI-RS candidate resource set in the LTE communication system, or partially overlap with the CSI-RS candidate resource set. For example, when the terminal device desires (e.g., may indicate to the terminal device through the network device) to obtain at least one of

symbols

5, 6, 12, and 13 as a time domain position of a CSI-RS resource of the NR communication system, the corresponding frequency domain position is at least one of

subcarriers

2, 3, 8, and 9; or when the terminal expects to receive the NR communication system CSI-RS resource at the time domain position of at least one of symbol 8, symbol 8 or symbol 10. At this time, it is necessary to find the pattern meeting the above requirements from the mapping patterns in the NR communication system, for example, pattern2, 3, 5, 7, or 8, that is, fig. 6b, fig. 6c, fig. 6e, fig. 6g, or fig. 6h can meet the requirements.

The reason for stipulating that the set of CSI-RS resources of the NR communication system is a subset of the set of CSI-RS candidate resources of the LTE communication system on the active BWP of the NR communication system is that the PDSCH resources of the LTE communication system will not be mapped on the set of CSI-RS candidate resources and interference with the measurement of CSI-RS of the NR communication system can be avoided by enabling zero-power CSI-RS configuration of the LTE communication system, so that the CSI on the active BWP of the NR communication system obtained based thereon is more accurate.

As an implementation manner, the network device may send second configuration information to the terminal device, where the second configuration information may be CSI configuration information, and is used for the terminal device to determine a reporting format (format) of CSI. The reporting format includes wideband reporting (wideband reporting) or subband reporting (subband reporting). When the broadband report is configured, the CSI is obtained by measuring based on the whole bandwidth configured for the terminal equipment; when the subband reporting is configured, the CSI is obtained by measuring the subband based on the bandwidth configured for the terminal equipment, and the number of the obtained CSI is multiple.

As an implementation manner, the network device may send, to the terminal device, first indication information for indicating a time domain position of a CSI-RS resource set of an NR communication system and a mapping pattern of CSI-RS of the NR communication system. Optionally, the first indication information may be included in Downlink Control Information (DCI) and indicated by a bit. The DCI may be a terminal device-level (UE-level) DCI or a group-level (group) DCI. Optionally, the network device and the terminal device may also agree, through a protocol, a mapping pattern of the CSI-RS of the NR communication system, and then indicate, through the second indication information, a time domain position of the CSI-RS resource set of the NR communication system. The former is more flexible, and the latter can save signaling overhead.

As one implementation, the CSI includes at least one of CQI, PMI, PTI, and RI.

In the second technical solution of the embodiment of the present application, by specifying that the CSI-RS resource set of the first communication system is a subset of the CSI-RS candidate resource set of the second communication system in the first frequency domain resource, the channel quality condition in the first communication system can be more accurately reflected, and loss of throughput and communication efficiency in the first communication system is avoided.

The embodiments in the present application can be used alone or in combination with each other to achieve different technical effects.
