Description

Technical Field

[0001] The present application relates to the technical field of wireless communication, and more specifically, to a method performed by a user equipment UE in a wireless communication system. Background Art

[0002] In order to meet the increased demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or quasi-5G communication systems. Therefore, 5G or quasi-5G communication systems are also referred to as "super 4G networks" or "post-LTE systems."

[0003] 5G communication systems are implemented in higher frequency (millimeter wave, mmWave) bands, such as the 60 GHz band, to achieve higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technology are discussed in 5G communication systems.

[0004] In addition, in the 5G communication system, development of system network improvements is underway based on advanced small cells, cloud radio access networks (RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, collaborative communications, coordinated multi-point (CoMP), receiving-end interference cancellation, etc.

[0005] In 5G systems, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) as advanced coded modulation (ACM), and filter bank multi-carrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) as advanced access technologies have been developed.

[0006] The transmission from the base station to the user equipment (UE) is called a downlink, and the transmission from the UE to the base station is called an uplink. Summary of the invention

[0007] In order to enhance the scheduling efficiency of 5G wireless communication systems, base stations need to obtain channel state information (CSI) in order to perform scheduling based on the CSI reported by terminal devices. However, how to further enhance the performance of CSI reporting is an unresolved issue.

[0008] One aspect of the present disclosure provides a method performed by a user equipment UE in a wireless communication system, the method comprising: receiving a channel state information CSI reporting configuration, wherein the CSI reporting configuration includes multiple first sub-configurations; determining and / or reporting a CSI parameter based on a second sub-configuration when a first condition is met, wherein the second sub-configuration includes at least one of the multiple first sub-configurations; wherein the CSI parameter corresponds to a resource for interference measurement associated with the second sub-configuration, wherein the resource for interference measurement is determined based on a resource for channel measurement corresponding to the CSI parameter, or the resource for interference measurement includes The second sub-configuration includes resources indicated by a second resource parameter; wherein the first condition includes at least one of the following: the multiple first sub-configurations include parameters for indicating type 2; the multiple first sub-configurations have the same channel state information reference signal CSI-RS port; the multiple first sub-configurations include parameters indicating resources used for channel measurement and / or interference measurement; the number of resources associated with the second sub-configuration for channel measurement is greater than 1; the CSI reporting configuration indicates non-periodic CSI reporting, semi-continuous CSI reporting or non-periodic CSI reporting; the resources associated with the multiple first sub-configurations for channel measurement and / or for interference measurement are non-periodic.

[0009] Another aspect of the present disclosure provides a method performed by a base station in a wireless communication system, the method comprising: sending a channel state information CSI reporting configuration, wherein the CSI reporting configuration includes multiple first sub-configurations; when a first condition is met, receiving a CSI parameter reported by a user equipment, wherein the CSI parameter is determined based on a second sub-configuration, and the second sub-configuration includes at least one of the multiple first sub-configurations; wherein the CSI parameter corresponds to a resource for interference measurement associated with the second sub-configuration, wherein the resource for interference measurement is determined based on the resource for channel measurement corresponding to the CSI parameter, or the resource for interference measurement is determined based on the resource for channel measurement corresponding to the CSI parameter, or the resource for interference measurement is determined based on the resource for channel measurement corresponding to the CSI parameter, or the resource for interference measurement is determined based on the resource for channel measurement corresponding to the CSI parameter, The measured resources include resources indicated by a second resource parameter; wherein the first condition includes at least one of the following: the multiple first sub-configurations include parameters for indicating type 2; the multiple first sub-configurations have the same channel state information reference signal CSI-RS port; the multiple first sub-configurations include parameters indicating resources used for channel measurement and / or interference measurement; the number of resources for channel measurement associated with the second sub-configuration is greater than 1; the configuration information for CSI reporting indicates non-periodic CSI reporting, semi-continuous CSI reporting or non-periodic CSI reporting; the resources for channel measurement and / or for interference measurement associated with the multiple first sub-configurations are non-periodic.

[0010] In one example, the CSI parameter corresponds to resources for channel measurement, wherein, when the CSI reporting configuration corresponds to multiple resource sets for channel measurement: the resources for channel measurement are indicated by multiple first resource parameters included in the second sub-configuration, or, the resources for channel measurement are indicated by a first resource parameter and a first resource set indication parameter included in the second sub-configuration, wherein the first resource set indication parameter is used to indicate one of the multiple resource sets for channel measurement, and the one first resource parameter is used to indicate one or more resources in the resource set indicated by the first resource set indication parameter.

[0011] In one example, the multiple resource sets for channel measurement correspond one-to-one to the multiple first resource parameters.

[0012] In one example, when the CSI reporting configuration corresponds to multiple resource sets for interference measurement: the resources for interference measurement are indicated by multiple second resource parameters included in the second sub-configuration; or the resources for interference measurement are indicated by a second resource parameter and a second resource set indication parameter included in the second sub-configuration, wherein the second resource set indication parameter is used to indicate one of the multiple resource sets for interference measurement; and the one second resource parameter is used to indicate one or more resources in the resource set indicated by the second resource set indication parameter.

[0013] In one example, the multiple resource sets for interference measurement correspond one-to-one to the multiple second resource parameters.

[0014] In one example, when the CSI parameter is a channel state information reference signal resource indicator CRI, and a value of CRI corresponding to a resource indicated by a first resource parameter included in the second sub-configuration and a value of CRI corresponding to a resource indicated by a second resource parameter included in the second sub-configuration and corresponding to the first resource parameter indication are equal, a channel quality indicator CQI corresponding to the CRI is calculated based on the resources indicated by the first resource parameter and the resources indicated by the second resource parameter.

[0015] In one example, the number of resources in the resource set for interference measurement corresponding to the CSI reporting configuration is equal to the total number of resources for channel measurement associated with the multiple first sub-configurations; and / or the order of resources in the resource set for interference measurement corresponding to the CSI reporting configuration is determined based on the order of the multiple first sub-configurations.

[0016] In one example, the number of resources for channel measurement associated with the multiple first sub-configurations is the total number of resources for channel measurement associated with the multiple first sub-configurations and in the resource set for channel measurement corresponding to the resource set for interference measurement.

[0017] In one example, the order of resources in the resource set for interference measurement corresponding to the CSI reporting configuration is: the order of the resources in the resource set for interference measurement in the resource set, or the order of resource identification IDs of the resources in the resource set for interference measurement; and / or, the order of the multiple first sub-configurations is: the order of the IDs of the multiple first sub-configurations, or the order of the multiple first sub-configurations in the CSI reporting configuration.

[0018] In one example, the resources for interference measurement associated with the second sub-configuration include: resources at a first position in a resource set for interference measurement corresponding to the CSI reporting configuration, wherein the first position is the same as the position of the resources for channel measurement associated with the second sub-configuration in a resource set for channel measurement corresponding to the CSI reporting configuration.

[0019] In one example, the number of resources used for interference measurement is equal to the number of resources used for channel measurement indicated by the first resource parameter included in the second sub-configuration.

[0020] In one example, when the CSI parameter is CRI, and the value of the CRI corresponding to the reference signal for channel measurement associated with the second subconfiguration and the value of the CRI corresponding to the reference signal for interference measurement associated with the second subconfiguration are equal, the reference signal for channel measurement associated with the second subconfiguration and the reference signal for interference measurement associated with the second subconfiguration are type D quasi-co-located.

[0021] In one example, the second sub-configuration is indicated by signaling that triggers CSI reporting corresponding to the CSI reporting configuration.

[0022] In one example, when the second sub-configuration includes a first resource set indication parameter and / or a second resource set indication parameter, the parameters associated with the trigger state indicated by the signaling do not include parameters for selecting a resource set for interference measurement and / or channel measurement corresponding to the CSI reporting configuration.

[0023] In one example, the number of resource sets for interference measurement and / or channel measurement corresponding to the CSI reporting configuration is 1.

[0024] In one example, when the UE is configured with a CSI non-periodic trigger state list parameter, the CSI non-periodic trigger state list parameter includes a CSI-related reporting configuration information parameter associated with the CSI reporting configuration; and when the fourth condition is met, the CSI-related reporting configuration information parameter does not include at least one of the channel resource parameters, resource group parameters, quasi-co-site QCL information parameters, CSI interference measurement CSI-IM resource parameters and non-zero power CSI-RS NZP CSI-RS resource parameters; wherein the fourth condition includes at least one of the following: the first sub-configuration includes at least one of the first resource set indication parameter and the second resource set indication parameter; the second sub-configuration includes at least one of the first resource set indication parameter and the second resource set indication parameter.

[0025] Another aspect of the present disclosure provides a user equipment, including: a transceiver; and a controller, coupled to the transceiver and configured to execute the above method that can be executed by the user equipment.

[0026] Another aspect of the present disclosure provides a base station, including: a transceiver; and a controller coupled to the transceiver and configured to execute the above method that can be executed by the controller.

[0027] The method proposed in this application improves the performance of CSI, thereby improving the scheduling efficiency of the communication system. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] For the same reason, in the accompanying drawings, some elements may be enlarged, omitted or schematically shown. In addition, the size of each element does not fully reflect the actual size. In the accompanying drawings, the same or corresponding elements have the same reference numerals.

[0039] By referring to the embodiments described in detail below in conjunction with the accompanying drawings, the advantages and features of the present disclosure and the ways to achieve them will become clear. However, the present disclosure is not limited to the embodiments set forth below, but can be implemented in various different forms. The following embodiments are provided only to fully disclose the present disclosure and inform those skilled in the art of the scope of the present disclosure, and the present disclosure is limited only by the scope of the attached claims. Throughout the specification, the same or similar reference numerals represent the same or similar elements.

[0040] Figure 1 An example wireless communication network 100 is shown in accordance with various embodiments of the present disclosure. Figure 1 The embodiment of the wireless communication network 100 shown in FIG. 1 is for illustration only. Other embodiments of the wireless communication network 100 may be used without departing from the scope of the present disclosure.

[0041] The wireless communication network 100 includes gNodeB (gNB) 101, gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one Internet Protocol (IP) network 130, such as the Internet, a private IP network, or other data network.

[0042] Depending on the type of network, other well-known terms such as “base station (BS)” or “access point (AP)” can be used instead of “gNodeB” or “gNB”. For convenience, the terms “gNodeB” and “gNB” are used in this disclosure to refer to network infrastructure components that provide wireless access to remote terminals. In addition, depending on the type of network, other well-known terms such as “mobile station”, “subscriber station”, “remote terminal”, “wireless terminal” or “user device” can be used instead of “user equipment” or “UE”. For convenience, the terms “user equipment” and “UE” are used in this disclosure to refer to a remote wireless device that wirelessly accesses a gNB, whether the UE is a mobile device (such as a mobile phone or a smart phone) or a commonly thought of fixed device (such as a desktop computer or a vending machine).

[0043] The gNB 102 provides wireless broadband access to a network 130 for a first plurality of user equipments (UEs) within a coverage area 120 of the gNB 102. The first plurality of UEs includes a UE 111 that may be located in a small business (SB), a UE 112 that may be located in an enterprise (E), a UE 113 that may be located in a WiFi hotspot (HS), a UE 114 that may be located in a first residence (R), a UE 115 that may be located in a second residence (R), and a UE 116 that may be a mobile device (M) such as a cellular phone, a wireless laptop, a wireless PDA, etc. The gNB 103 provides wireless broadband access to the network 130 for a second plurality of UEs within a coverage area 125 of the gNB 103. The second plurality of UEs includes UE 115 and UE 116. In some embodiments, one or more of the gNBs 101-103 may be capable of communicating with each other and with the UEs 111-116 using 5G, Long Term Evolution (LTE), LTE-A, WiMAX, or other advanced wireless communication technologies.

[0044] The dashed lines illustrate the approximate extents of coverage areas 120 and 125, which are shown as approximately circular for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with gNBs, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0045] As described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook design and structure for a system with a 2D antenna array.

[0046] although Figure 1 An example of a wireless communication network 100 is shown, but Figure 1 Various changes may be made. For example, the wireless communication network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Also, gNB 101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. In addition, gNB 101, gNB 102, and / or gNB 103 can provide access to other or additional external networks, such as an external telephone network or other type of data network.

[0047] Figure 2A and Figure 2B A transmit path 200 and a receive path 250 in a wireless communication network according to various embodiments of the present disclosure are shown, respectively. In the following description, the transmit path 200 can be described as being implemented in a gNB (such as gNB 102), and the receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that the receive path 250 can be implemented in a gNB and the transmit path 200 can be implemented in a UE. In some embodiments, the receive path 250 is configured to support codebook design and structure for a system having a 2D antenna array as described in embodiments of the present disclosure.

[0048] The transmit path 200 includes a channel coding and modulation block 205, a serial to parallel (S to P) block 210, an N-point inverse fast Fourier transform (IFFT) block 215, a parallel to serial (P to S) block 220, an add cyclic prefix block 225, and an upconverter (UC) 230. The receive path 250 includes a downconverter (DC) 255, a remove cyclic prefix block 260, a serial to parallel (S to P) block 265, an N-point fast Fourier transform (FFT) block 270, a parallel to serial (P to S) block 275, and a channel decoding and demodulation block 280.

[0049] In the transmit path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as low-density parity check (LDPC) coding), and modulates the input bits (such as using quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a sequence of frequency-domain modulation symbols. The serial-to-parallel (S-to-P) block 210 converts (such as demultiplexes) the serial modulation symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in the gNB 102 and the UE 116. The N-point IFFT block 215 performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. The parallel-to-serial block 220 converts (such as multiplexes) the parallel time-domain output symbols from the N-point IFFT block 215 to generate a serial time-domain signal. The add cyclic prefix block 225 inserts a cyclic prefix into the time-domain signal. The up-converter 230 modulates (such as up-converts) the output of the add cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at baseband before conversion to RF frequency.

[0050] The RF signal transmitted from gNB 102 arrives at UE 116 after passing through the wireless channel, and the reverse operation of the operation at gNB 102 is performed at UE 116. Downconverter 255 downconverts the received signal to baseband frequency, and remove cyclic prefix block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial to parallel block 265 converts the time-domain baseband signal into parallel time-domain signals. N-point FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel to serial block 275 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0051] Each of gNBs 101-103 may implement a transmit path 200 similar to that for transmitting in the downlink to UEs 111-116 and may implement a receive path 250 similar to that for receiving in the uplink from UEs 111-116. Similarly, each of UEs 111-116 may implement a transmit path 200 for transmitting in the uplink to gNBs 101-103 and may implement a receive path 250 for receiving in the downlink from gNBs 101-103.

[0052] Figure 2A and Figure 2B Each of the components in can be implemented using hardware only, or a combination of hardware and software / firmware. As a specific example, Figure 2A and Figure 2BAt least some of the components in can be implemented with software, while other components can be implemented by configurable hardware or a combination of software and configurable hardware. For example, FFT block 270 and IFFT block 215 can be implemented as a configurable software algorithm, in which the value of the number of points N can be modified according to the implementation.

[0053] In addition, although described as using FFT and IFFT, this is illustrative only and should not be construed as limiting the scope of the present disclosure. Other types of transforms can be used, such as discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) functions. It should be understood that for DFT and IDFT functions, the value of variable N can be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N can be any integer as a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0054] although Figure 2A and Figure 2B An example of a wireless transmit and receive path is shown, but the Figure 2A and Figure 2B Make various changes. For example, Figure 2A and Figure 2B The various components in can be combined, further subdivided or omitted, and additional components can be added according to specific needs. Figure 2A and Figure 2B It is intended to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communications in a wireless network.

[0055] Figure 3A An example UE 116 is shown in accordance with various embodiments of the present disclosure. Figure 3A The embodiment of UE 116 shown in FIG. 1 is for illustration only, and Figure 1 UEs 111-115 can have the same or similar configurations. However, UEs have a variety of configurations, and Figure 3A The scope of the present disclosure is not limited to any particular implementation of the UE.

[0056] UE 116 includes antenna 305, radio frequency (RF) transceiver 310, transmit (TX) processing circuit 315, microphone 320, and receive (RX) processing circuit 325. UE 116 also includes speaker 330, processor / controller 340, input / output (I / O) interface 345, input device(s) 350, display 355, and memory 360. Memory 360 includes operating system (OS) 361 and one or more applications 362.

[0057] The RF transceiver 310 receives incoming RF signals from the antenna 305 transmitted by the gNB of the wireless network 100. The RF transceiver 310 downconverts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to the RX processing circuit 325, where the RX processing circuit 325 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuit 325 sends the processed baseband signal to the speaker 330 (such as for voice data) or to the processor / controller 340 (such as for web browsing data) for further processing.

[0058] The TX processing circuit 315 receives analog or digital voice data from the microphone 320, or receives other outgoing baseband data (such as network data, email, or interactive video game data) from the processor / controller 340. The TX processing circuit 315 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 310 receives the outgoing processed baseband or IF signal from the TX processing circuit 315 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 305.

[0059] The processor / controller 340 can include one or more processors or other processing devices and execute an OS 361 stored in the memory 360 to control the overall operation of the UE 116. For example, the processor / controller 340 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceiver 310, the RX processing circuit 325, and the TX processing circuit 315 according to well-known principles. In some embodiments, the processor / controller 340 includes at least one microprocessor or microcontroller.

[0060] The processor / controller 340 is also capable of executing other processes and programs resident in the memory 360, such as operations for channel quality measurement and reporting of a system having a 2D antenna array as described in the embodiments of the present disclosure. The processor / controller 340 is capable of moving data into or out of the memory 360 as required by the execution process. In some embodiments, the processor / controller 340 is configured to execute an application 362 based on the OS 361 or in response to a signal received from a gNB or operator. The processor / controller 340 is also coupled to an I / O interface 345, where the I / O interface 345 provides the UE 116 with the ability to connect to other devices such as laptops and handheld devices. The I / O interface 345 is a communication path between these accessories and the processor / controller 340.

[0061] Processor / controller 340 is also coupled to input device(s) 350 and display 355. An operator of UE 116 can input data into UE 116 using input device(s) 350. Display 355 can be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). Memory 360 is coupled to processor / controller 340. A portion of memory 360 can include random access memory (RAM), while another portion of memory 360 can include flash memory or other read-only memory (ROM).

[0062] although Figure 3A An example of UE 116 is shown, but it is possible to Figure 3A Make various changes. For example, Figure 3A The various components in can be combined, further subdivided, or omitted, and additional components can be added as required. As a specific example, processor / controller 340 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). In addition, although Figure 3A The UE 116 is shown configured as a mobile phone or smart phone, but the UE can be configured to operate as other types of mobile or stationary devices.

[0063] Figure 3B An example gNB 102 is shown in accordance with various embodiments of the present disclosure. Figure 3B The embodiment of the gNB 102 shown in FIG. is for illustration only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a variety of configurations, and Figure 3B The scope of the present disclosure is not limited to any particular implementation of the gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structure as gNB 102.

[0064] like Figure 3B As shown in FIG. 1 , gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376. In some embodiments, one or more of the multiple antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0065] The RF transceivers 372a-372n receive incoming RF signals from the antennas 370a-370n, such as signals transmitted by a UE or other gNB. The RF transceivers 372a-372n downconvert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to the RX processing circuitry 376, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry 376 sends the processed baseband signals to the controller / processor 378 for further processing.

[0066] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from the controller / processor 378. The TX processing circuit 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceivers 372a-372n receive the outgoing processed baseband or IF signals from the TX processing circuit 374 and up-convert the baseband or IF signals to RF signals that are transmitted via the antennas 370a-370n.

[0067] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceivers 372a-372n, the RX processing circuitry 376, and the TX processing circuitry 374 in accordance with well-known principles. The controller / processor 378 can also support additional functionality, such as more advanced wireless communication functionality. For example, the controller / processor 378 can perform a Blind Interference Sensing (BIS) process, such as performed through a Blind Interference Sensing (BIS) algorithm, and decode a received signal with an interference signal subtracted. The controller / processor 378 can support any of a variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0068] The controller / processor 378 can also execute programs and other processes resident in the memory 380, such as a basic OS. The controller / processor 378 can also support channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communications between entities such as web RTC. The controller / processor 378 can move data into or out of the memory 380 as needed by the executing process.

[0069] The controller / processor 378 is also coupled to a backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or via a network. The backhaul or network interface 382 can support communication via any suitable (multiple) wired or wireless connections. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G or new radio access technology or NR, LTE or LTE-A), the backhaul or network interface 382 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow the gNB 102 to communicate with a larger network (such as the Internet) via a wired or wireless local area network or via a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication via a wired or wireless connection, such as an Ethernet or RF transceiver.

[0070] The memory 380 is coupled to the controller / processor 378. A portion of the memory 380 can include RAM, while another portion of the memory 380 can include flash memory or other ROM. In some embodiments, a plurality of instructions such as a BIS algorithm are stored in the memory. The plurality of instructions are configured to cause the controller / processor 378 to perform the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.

[0071] As described in more detail below, the transmit and receive paths of the gNB 102 (implemented using the RF transceivers 372a-372n, the TX processing circuitry 374, and / or the RX processing circuitry 376) support aggregated communications with FDD cells and TDD cells.

[0072] although Figure 3B An example of a gNB 102 is shown, but the Figure 3B For example, gNB 102 can include any number of Figure 3B . As a specific example, the access point can include multiple backhaul or network interfaces 382, ​​and the controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as including a single instance of TX processing circuitry 374 and a single instance of RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0073] Currently, in wireless communication systems, user equipment (UE) can only obtain power parameters and / or spatial parameter changes on the network equipment side in a semi-static manner, which cannot meet the requirements of flexible adjustment on the base station side.

[0074] Various embodiments of the present application are described in detail below with reference to the accompanying drawings. Figure 4 A method 400 performed by a user equipment (UE) according to various embodiments of the present disclosure is shown. The method 400 includes: at 401, the UE receives configuration information for CSI reporting; at 402, the UE determines and / or reports CSI based on the received configuration information for CSI reporting. In this document, the term "CSI reporting configuration information" can be used interchangeably with the terms "configuration information for CSI reporting" and "information for configuring CSI reporting".

[0075] Embodiment 1

[0076] The UE receives CSI reporting configuration information (e.g., CSI-ReportConfig). Optionally, the CSI reporting configuration information is associated / corresponds to / includes one or more first sub-configurations. Here, the sub-configuration may be referred to as sub-configuration information. Optionally, the first sub-configuration may be sub-configuration information of the CSI report.

[0077] Optionally, the second subconfiguration includes one of the one or more first subconfigurations. Optionally, the second subconfiguration is a subconfiguration (e.g., one, or any one, or each, or all) of the multiple first subconfigurations. For example, when the CSI reporting configuration information corresponds to periodic CSI reporting, the second subconfiguration is a subconfiguration (e.g., one, or any one, or each) of the one or more first subconfigurations. Optionally, when the CSI reporting configuration information corresponds to periodic CSI reporting, each report (report instance) of the periodic CSI reporting is for all subconfigurations in the one or more first subconfigurations. For example, the number of one or more first subconfigurations may be L, where L>1 (or, L>=1). For example, the number of one or more first subconfigurations may be L, where L>1 (or, L>=1). For example, taking the example that the second subconfiguration is all subconfigurations in a subset of one or more first subconfigurations, the number of second subconfigurations may be N, where N<=L and / or N>=1. Optionally, for the case where the CSI reporting is periodic CSI reporting, N=L. For example, the CSI report includes CSI parameters corresponding to all subconfigurations in one or more first subconfigurations. Optionally, the CSI reporting configuration information corresponding to periodic CSI reporting means that the reporting type parameter (reportConfigType) in the CSI reporting configuration information (eg, CSI-ReportConfig) is set to "periodic".

[0078] Optionally, the second subconfiguration includes a subset of one or more first subconfigurations. Optionally, the second subconfiguration is a first subconfiguration in a subset of one or more first subconfigurations (e.g., one, or, any one, or, each, or all). For example, when the CSI reporting configuration information corresponds to semi-continuous CSI reporting or non-periodic CSI reporting, the second subconfiguration may be a first subconfiguration in a subset of one or more first subconfigurations (e.g., one, or, any one, or each, or all). For example, the number of one or more first subconfigurations may be L, where L>1 (or, L>=1). For example, taking the example that the second subconfiguration is all subconfigurations in a subset of one or more first subconfigurations, the number of second subconfigurations may be N, where N<=L and / or N>=1. Optionally, the subset is indicated (or provided) by signaling that triggers / activates / schedules / indicates the CSI reporting corresponding to the CSI reporting configuration information. For example, the CSI reporting configuration information includes (or is configured with) L sub-configurations, and a signaling can trigger / activate / schedule / indicate the CSI reporting corresponding to the CSI reporting configuration information, and the signaling can indicate that N sub-configurations of the L sub-configurations are used for CSI reporting. For example, the UE generates / determines (generates / derives) CSI (e.g., CSI parameters) corresponding to N sub-configurations of the L sub-configurations, and puts them into the CSI reporting. For example, if the CSI reporting configuration information corresponds to semi-persistent CSI reporting on a physical uplink control channel (PUCCH), and the CSI reporting configuration information includes (or is configured with) L sub-configurations, a media access control element (MAC-CE) signaling can trigger the CSI reporting corresponding to the CSI reporting configuration information (e.g., the CSI reporting is carried by the PUCCH), and the MAC-CE signaling can include indication information for indicating that N sub-configurations from the L sub-configurations are used for CSI reporting. For example, if the CSI reporting configuration information corresponds to semi-persistent CSI reporting on a physical uplink shared channel (PUSCH), and the CSI reporting configuration information includes (or is configured with) L sub-configurations, then a downlink control information (DCI) (or DCI format) can trigger the CSI reporting corresponding to the CSI reporting configuration information (for example, the CSI reporting is carried by PUSCH), and the DCI can indicate a triggering state. Optionally, the triggering state is associated with N sub-configurations (of the L sub-configurations) (or the triggering state can indicate N configurations) for CSI reporting. Optionally, the DCI format can be DCI format 0_1 ​​or DCI format 0_2.For example, if the CSI reporting configuration information corresponds to non-periodic CSI reporting, and the CSI reporting configuration information includes (or is configured with) L sub-configurations, then a DCI (or DCI format) can trigger the CSI reporting corresponding to the CSI reporting configuration information (for example, the CSI reporting is carried by PUSCH), and the DCI can indicate a triggering state. Optionally, the triggering state is associated with N sub-configurations (of the L sub-configurations) (or the triggering state indicates N configurations) for CSI reporting. Optionally, the DCI format can be DCI format 0_1 ​​or DCI format 0_2. Optionally, the CSI reporting configuration information corresponding to semi-persistent CSI reporting on PUCCH means that the reporting type parameter (reportConfigType) in the CSI reporting configuration information (for example, CSI-ReportConfig) is set to "semi-persistent reporting on PUCCH (semiPersistentOnPUCCH)". Optionally, the CSI reporting configuration information corresponding to semi-persistent CSI reporting on PUSCH means that a reporting type parameter (reportConfigType) in the CSI reporting configuration information (e.g., CSI-ReportConfig) is set to "semi-persistent reporting on PUSCH (semiPersistentOnPUSCH)". Optionally, the CSI reporting configuration information corresponding to aperiodic CSI reporting means that a reporting type parameter (reportConfigType) in the CSI reporting configuration information (e.g., CSI-ReportConfig) is set to "aperiodic".

[0079] Optionally, the description of the second subconfiguration in the present disclosure may apply to one subconfiguration, each subconfiguration, or any subconfiguration in one or more first subconfigurations. Optionally, the description of the second subconfiguration in the present disclosure may apply to one subconfiguration, each subconfiguration, or any subconfiguration in a subset of one or more first subconfigurations. Optionally, in the present disclosure, the second subconfiguration may be equivalent to one or more first subconfigurations. Optionally, in the present disclosure, the second subconfiguration may be equivalent to the first subconfiguration.

[0080] Optionally, the UE determines a CSI parameter based on the second sub-configuration.

Optionally, determining the CSI parameter may be determining CSI feedback. Determining the CSI parameter may also be determining a report carrying the CSI parameter (i.e., determining the CSI report). Optionally, the CSI parameter may be CSI feedback. The CSI parameter may also be a report carrying the CSI parameter (i.e., CSI reporting).

[0081] Optionally, the CSI parameter may be at least one of a channel state information reference signal (CSI-RS) resource indicator (CSI-RSResource Indicator, CRI), a rank indicator (Rank Indicator, RI), a precoding matrix indicator (Precoding Matrix Indicator, PMI), a channel quality indicator (CQI), and a layer indicator (layer indicator, LI). Optionally, the CSI parameter may be at least one of a CSI-RS resource indicator (CSI-RS Resource Indicator, CRI), an SSB resource indicator (SS / PBCH Block Resourceindicator, SSBRI), a layer 1-reference signal received power (L1-RSRP), a layer 1-signal interference and noise ratio (L1-SINR), and a capability index (CapabilityIndex).

[0082] Optionally, the UE determines the second CSI parameter of the second subconfiguration based on the first CSI parameter of the second subconfiguration. Optionally, when the first condition is met, the UE determines the second CSI parameter of the second subconfiguration based on the first CSI parameter of the second subconfiguration. Optionally, when the first condition is met, the UE determines the CSI parameter based on the second subconfiguration. Optionally, the first CSI parameter may be CRI.

[0089] ●The CSI configuration information corresponds to one of aperiodic CSI reporting, semi-persistent CSI reporting and aperiodic CSI reporting;

[0090] ● The resources for channel measurement and / or for interference measurement of the second sub-configuration (associated) are non-periodic. Optionally, the resource type parameter (e.g., resourceType) of the CSI resource setting (CSI-ResourceConfig) (for channel measurement and / or for interference measurement) corresponding to the CSI reporting configuration information of the second sub-configuration is set to "non-periodic";

[0091] ● The resources for channel measurement and / or for interference measurement included / corresponding / associated / indicated by one or more first sub-configurations (one or all of them) are non-periodic. Optionally, the resource type parameter (e.g., resourceType) of the CSI resource setting (CSI-ResourceConfig) (for channel measurement and / or for interference measurement) corresponding to the CSI reporting configuration information of one or more first sub-configurations is set to "non-periodic".

[0092] Optionally, the first CSI parameter corresponds to the resources for channel measurement of the second sub-configuration and / or the resources for interference measurement of the second sub-configuration. Here, the first CSI parameter is described by CRI as an example. CRI (or, the value of CRI) is represented by parameter k. Optionally, k is a positive integer greater than or equal to 0 (k>=0). For example, different values ​​of k represent different resources for channel measurement and / or resources for interference measurement. Optionally, the corresponding (reported) CRI of the second sub-configuration corresponds to the resources for channel measurement (e.g., reference signal resources) of the second sub-configuration. Optionally, when the number of resources for channel measurement of the second sub-configuration is greater than 1, the CRI corresponding to the second sub-configuration is reported. Optionally, when the number of resources for channel measurement of the second sub-configuration is equal to 1, the value of the CRI corresponding to the second sub-configuration can be (or can be considered to be) a specific value (e.g., 0 or 1).

[0093] Optionally, the resources for channel measurement of the second sub-configuration include / refer to the resources indicated by the first resource parameter included / associated with the second sub-configuration. Optionally, the second sub-configuration may include a first resource parameter. Optionally, the first resource parameter is used to indicate one or more resources for channel measurement.

Optionally, the resource comprises a CSI-RS resource or a channel state information interference measurement (CSI-IM) resource. Optionally, the CSI-RS may be a non-zero power (NZP) CSI-RS.

[0094] Optionally, the mapping relationship between the first resource parameter and the resource indicated by it may be determined by one of the following methods:

[0095] Method 1

[0096] The first resource parameter is a list. Optionally, one item (or each item) of the list indicates a resource identifier (ID) (for example, a CSI-RS resource ID). Optionally, the resource corresponding to the resource ID belongs to the resource set for channel measurement corresponding to the CSI reporting configuration information (for example, NZP-CSI-RS-ResourceSet). For example, the resource set for channel measurement corresponding to the CSI reporting configuration information is {CSI-RS#1, CSI-RS#3, CSI-RS#4, CSI-RS#7}, and the first resource parameter indicates {#1, #7}, then the channel measurement resource corresponding to the second sub-configuration is {CSI-RS#1, CSI-RS#7}. The terminal device uses the reference signal resource corresponding to the resource ID indicated by the list to perform channel measurement (instead of using all reference signal resources in the resource set for channel measurement corresponding to the CSI reporting configuration information for channel measurement).

[0097] Method 2

[0098] The first resource parameter is a list. Optionally, one item (or each item) of the list indicates the index of a resource in a resource set. For example, the first resource of the resource set is index 0, the second resource of the resource set is index 1, and so on. Optionally, the resource set refers to / includes a resource set for channel measurement corresponding to the CSI reporting configuration information (for example, NZP-CSI-RS-ResourceSet). For example, the resource set for channel measurement corresponding to the CSI reporting configuration information is {CSI-RS#1, CSI-RS#3, CSI-RS#4, CSI-RS#7}, and the first resource parameter indicates {0, 2}, then the channel measurement reference signal resource corresponding to the second sub-configuration is {CSI-RS#1, CSI-RS#4}. The terminal device uses the resources indicated by the list for channel measurement (instead of using all resources in the resource set for channel measurement corresponding to the CSI reporting configuration information for channel measurement).

[0099] The above two methods can clarify the mapping relationship between the first resource parameter and the corresponding resource, thereby improving the reliability of the communication system.

[0100] Optionally, the resource for channel measurement corresponding to the second sub-configuration of the first CSI parameter refers to the resource for channel measurement (for example, a reference signal resource) indicated by the first resource parameter of the second sub-configuration corresponding to the first CSI parameter. Taking the first CSI parameter as CRI as an example, there is a mapping relationship between CRI and the resource for channel measurement indicated by the first resource parameter. The mapping relationship can be determined by at least one of the following methods:

[0101] Method 1

[0102] CRI is determined based on the order / position of the resources for channel measurement indicated by the first resource parameter in the resource set for channel measurement corresponding to the CSI reporting configuration information. Optionally, the value k corresponding to CRI represents the k+1th resource in the resource set for channel measurement corresponding to the CSI reporting configuration information indicated by the first resource parameter. For example, the resource set for channel measurement corresponding to the CSI reporting configuration information is {CSI-RS#1, CSI-RS#3, CSI-RS#4, CSI-RS#7}, and the first resource parameter indicates CSI-RS#4 and CSI-RS#1, then k=0 corresponds to CSI-RS#1; k=1 corresponds to CSI-RS#4.

[0103] Method 2

[0104] CRI is determined based on the order / position of the resources for channel measurement indicated by the first resource parameter in the first resource parameter. Optionally, the value k corresponding to CRI represents the resources indicated by the k+1th item of the first resource parameter. For example, the resource set for channel measurement corresponding to the CSI reporting configuration information is {CSI-RS#1, CSI-RS#3, CSI-RS#4, CSI-RS#7}, and the first resource parameter indicates CSI-RS#4 and CSI-RS#1 (for example, CSI-RS#4 corresponds to the first item of the first resource parameter; CSI-RS#1 corresponds to the second item of the first resource parameter), then k=0 corresponds to CSI-RS#4; k=1 corresponds to CSI-RS#1.

[0105] Method 3

[0106] CRI is determined based on the order (e.g., order of size) of the resource IDs for channel measurement indicated by the first resource parameter. For example, from small to large or from large to small. Optionally, the resource ID may be a configured ID. Optionally, the value k corresponding to the CRI represents the resource with the k+1th largest (or, the k+1th smallest) ID in the resources indicated by the first resource parameter. Taking the example that the value k corresponding to the CRI represents the resource with the k+1th smallest ID in the resources indicated by the first resource parameter, the resource set for channel measurement corresponding to the CSI reporting configuration information is {CSI-RS#3, CSI-RS#1, CSI-RS#4, CSI-RS#7}, and the first resource parameter indicates {CSI-RS#3, CSI-RS#1, CSI-RS#4}, then k=0 corresponds to CSI-RS#1; k=1 corresponds to CSI-RS#3; k=2 corresponds to CSI-RS#4.

[0107] For a sub-configuration, the terminal device can measure the resources indicated by the first resource parameter, select at least one resource (for example, the resource with the highest corresponding signal-to-noise ratio), and feed back the information of the resource to the base station. Clarifying the mapping relationship between the resources indicated by the first resource parameter and the CRI can avoid different understandings of the reported information between the terminal device and the base station. The above method can clarify the mapping relationship between CRI (or k) and the corresponding resources, and improve the reliability of the communication system.

[0108] Optionally, when the second condition is met, the second sub-configuration includes / is associated with / corresponds to / indicates at least one of the following: multiple first resource parameters; or, a first resource parameter and / or a first resource set indication parameter. Optionally, the second condition includes at least one of the following:

[0109] ●The CSI reporting configuration information corresponds to multiple (non-periodic) resource sets. Optionally, the resource set may be used for channel measurement and / or for interference measurement. Optionally, the resource setting (resource setting) for channel measurement corresponding to (or associated with) the CSI reporting configuration information includes multiple (non-periodic) resource sets. For example, the CSI-ResourceConfig configured by the resourcesForChannelMeasurement parameter of CSI-ReportConfig includes multiple resource sets (e.g., NZP-CSI-RS-ResourceSet);

[0110] ●The CSI reporting configuration information corresponds to a non-periodic resource set. Optionally, the resource set may be used for channel measurement and / or for interference measurement. Optionally, the resource setting (resource setting) for channel measurement corresponding to (or associated with) the CSI reporting configuration information includes a non-periodic resource set. For example, the CSI-ResourceConfig configured by the resourcesForChannelMeasurement parameter of CSI-ReportConfig includes a resource set (e.g., NZP-CSI-RS-ResourceSet). For example, the resource type of the resource setting is non-periodic;

[0111] ●The UE is configured with the CSI aperiodic trigger state list parameter (CSI-AperiodicTriggerStateList).

[0112] Optionally, the second sub-configuration includes / is associated with / corresponds to / indicates multiple first resource parameters. Optionally, the CSI reporting configuration information corresponds to multiple resource sets (for channel measurement). Optionally, the number of multiple resource sets (for channel measurement) corresponding to the CSI reporting configuration information is equal to the number of multiple first resource parameters. Optionally, the multiple resource sets for channel measurement corresponding to the CSI reporting configuration information are in one-to-one correspondence with the multiple first resource parameters. Optionally, the one-to-one correspondence may be a one-to-one correspondence in order. Optionally, the order may be determined based on the (sequential) order / position of multiple resource sets for channel measurement in the resource setting and / or the (sequential) order / position of multiple first resource parameters in the corresponding list. For example, the CSI reporting configuration information (in the corresponding resource setting) includes 3 resource sets for channel measurement, namely {CSI-RS#1, CSI-RS#2, CSI-RS#3, CSI-RS#4}, {CSI-RS#5, CSI-RS#6}, {CSI-RS#7, CSI-RS#8, CSI-RS#9, CSI-RS#10}, and the 3 first resource parameters respectively indicate {CSI-RS#1, CSI-RS#4}, {CSI-RS#6}, {CSI-RS#9, CSI-RS#10}. The 3 resource sets correspond to the 3 first resource parameters in order. Optionally, the method of using (each) first resource parameter is as described above.

[0113] Optionally, (for a CSI report) (only) one of the multiple (non-periodic) resource sets in the resource setting is associated with a trigger state. Optionally, each trigger state of each resource setting may be configured with parameters for selecting a resource set in the resource setting. Optionally, the UE receives trigger signaling (e.g., DCI format) for a non-periodic CSI report. Optionally, the trigger signaling may indicate a trigger state. The UE may determine one of the multiple (non-periodic) resource sets in the resource setting based on the parameters associated with the trigger state (or, the parameters configured for the trigger state). Optionally, the selected / indicated (non-periodic) resource set determines the reference signal resource (for channel measurement) based on the corresponding first resource parameter. Optionally, for the corresponding (or, selected) resource set, the method for using the first resource parameter is as described above.

Optionally, the first resource parameter is used to indicate a reference signal (for channel measurement) corresponding to the CSI reporting configuration information. Optionally, for the corresponding (or selected) resource set, the method for using the first resource parameter is as described above. For example, the CSI reporting configuration information (in the corresponding resource setting) includes 3 resource sets for channel measurement, namely {CSI-RS#1, CSI-RS#2, CSI-RS#3, CSI-RS#4}, {CSI-RS#5, CSI-RS#6}, {CSI-RS#7, CSI-RS#8, CSI-RS#9, CSI-RS#10}, a first resource set indication parameter indicating {0}, and a first resource parameter indicating {CSI-RS#1, CSI-RS#4}. Here, if the first resource set indication parameter indicates 0 (or, indicates the first state), it means that the first resource set is indicated; if it indicates 1 (or, indicates the second state), it means that the second resource set is indicated, and so on. Here, the first resource parameter can be used to indicate the resources (e.g., reference signal resources) in the resource set indicated by the first resource set indication parameter.

[0115] Optionally, the first CSI parameter corresponds to the resources for channel measurement of the second sub-configuration and / or the resources for interference measurement of the second sub-configuration. Here, the first CSI parameter is described by CRI as an example. CRI (or, the value of CRI) is represented by parameter k. Optionally, k is a positive integer greater than or equal to 0 (k>=0). For example, different values ​​of k represent different reference signals for channel measurement and / or resources for interference measurement. Optionally, the corresponding (reported) CRI of the second sub-configuration corresponds to the resources for interference measurement of the second sub-configuration. Optionally, when the number of resources for interference measurement of the second sub-configuration is greater than 1, the CRI corresponding to the second sub-configuration is reported. Optionally, when the number of resources for interference measurement of the second sub-configuration is equal to 1, the value of the CRI corresponding to the second sub-configuration can be (or can be considered to be) a specific value (for example, 0 or 1).

For example, the CSI resource setting is associated / corresponding to the CSI-IM resource parameter (e.g., csi-IM-ResourcesForInterference) for interference measurement in the CSI reporting configuration information. The CSI resource setting is, for example, CSI-ResourceConfig. Optionally, the third resource parameter is used to indicate one or more resources for interference measurement.

[0119] The second resource parameter is a list. Optionally, one item (or each item) of the list indicates a resource ID (for example, a CSI-IM resource ID). Optionally, the resource corresponding to the resource ID belongs to the resource set for interference measurement corresponding to the CSI reporting configuration information (for example, CSI-IM-ResourceSet). For example, the resource set for interference measurement corresponding to the CSI reporting configuration information is {CSI-IM#1, CSI-IM#3, CSI-IM#4, CSI-IM#7}, and the second resource parameter indicates {#1, #7}, then the interference measurement resource corresponding to the second sub-configuration is {CSI-IM#1, CSI-IM#7}. The terminal device uses the resources corresponding to the resource ID indicated by the list for interference measurement (instead of using all resources in the resource set for interference measurement corresponding to the CSI reporting configuration information for interference measurement).

[0120] Method 2

[0121] The second resource parameter is a list. Optionally, one item (or each item) of the list indicates the index of a resource in a resource set. For example, the first resource of the resource set is index 0, the second reference signal resource of the resource set is index 1, and so on. Optionally, the resource set refers to / includes a resource set for interference measurement corresponding to the CSI reporting configuration information (e.g., CSI-IM-ResourceSet). For example, the set for interference measurement corresponding to the CSI reporting configuration information is {CSI-IM#1, CSI-IM#3, CSI-IM#4, CSI-IM#7}, and the second resource parameter indicates {0, 2}, then the interference measurement resource corresponding to the second sub-configuration is {CSI-IM#1, CSI-IM#4}. The terminal device uses the resources indicated by the list for interference measurement (instead of using all resources in the resource set for interference measurement corresponding to the CSI reporting configuration information for interference measurement).

[0122] The above method can clarify the mapping relationship between the second resource parameter and the corresponding resource, and improve the reliability of the communication system.

[0123] Optionally, the resource for interference measurement corresponding to the second sub-configuration of the first CSI parameter refers to the resource for interference measurement indicated by the second resource parameter of the second sub-configuration corresponding to the first CSI parameter. Taking the first CSI parameter as CRI as an example, there is a mapping relationship between CRI and the resource for interference measurement indicated by the second resource parameter. The mapping relationship can be determined by one of the following methods:

[0124] Method 1

[0125] CRI is determined based on the order / position of the resources for interference measurement indicated by the second resource parameter in the resource set for interference measurement corresponding to the CSI reporting configuration information. Optionally, the value k corresponding to CRI represents the k+1th resource in the resource set for interference measurement corresponding to the CSI reporting configuration information indicated by the second resource parameter. For example, the resource set for interference measurement corresponding to the CSI reporting configuration information is {CSI-IM#1, CSI-IM#3, CSI-IM#4, CSI-IM#7}, and the second resource parameter indicates CSI-IM#4 and CSI-IM#1, then k=0 corresponds to CSI-IM#1; k=1 corresponds to CSI-IM#4.

[0126] Method 2

[0127] CRI is determined based on the order / position of the resources for interference measurement indicated by the second resource parameter in the second resource parameter. Optionally, the value k corresponding to CRI represents the resource indicated by the k+1th item of the second resource parameter. For example, the resource set for interference measurement corresponding to the CSI reporting configuration information is {CSI-IM#1, CSI-IM#3, CSI-IM#4, CSI-IM#7}, and the second resource parameter indicates CSI-IM#4 and CSI-IM#1 (for example, CSI-RS#4 corresponds to the first item of the second resource parameter; CSI-IM#1 corresponds to the second item of the second resource parameter), then k=0 corresponds to CSI-IM#4; k=1 corresponds to CSI-IM#1.

[0128] Method 3

[0129] CRI is determined based on the order (e.g., order of size) of the resource IDs used for interference measurement indicated by the second resource parameter. For example, from small to large or from large to small. Optionally, the value k corresponding to CRI represents the resource with the k+1th largest ID (or, the k+1th smallest) in the resources indicated by the second resource parameter. Taking the example that the value k corresponding to CRI represents the resource with the k+1th smallest ID in the resources indicated by the second resource parameter, the resource set for interference measurement corresponding to the CSI reporting configuration information is {CSI-IM#3, CSI-IM#1, CSI-IM#4, CSI-IM#7}, and the second resource parameter indicates {CSI-IM#3, CSI-IM#1, CSI-IM#4}, then k=0 corresponds to CSI-RS#1; k=1 corresponds to CSI-IM#3; k=2 corresponds to CSI-IM#4.

[0130] The above method can clarify the mapping relationship between CRI (or k) and the corresponding resources, and improve the reliability of the communication system. Based on the above methods one to three, a CRI value can be associated with a resource for channel measurement and at least one resource for interference resources. Different CRI values ​​can be associated with different resource pairs, where each resource pair may include a resource for channel measurement and one or more resources for interference resources. Thus, the terminal device performs channel measurement and interference measurement on the resources in different resource pairs, selects at least one resource pair, and reports the corresponding information to the base station. Clarifying the mapping relationship between the resources indicated by the second resource parameter (and / or the resources indicated by the first resource parameter) and the CRI can avoid different understandings of the reported information between the terminal device and the base station.

[0131] Optionally, when the second condition is met, the second sub-configuration includes / is associated with / corresponds to / indicates at least one of the following: multiple second resource parameters; or, a second resource parameter and / or a second resource set indication parameter. Optionally, the second condition includes at least one of the following:

[0132] ●The CSI reporting configuration information corresponds to multiple (non-periodic) resource sets. Optionally, the resource set may be used for channel measurement and / or for interference measurement. Optionally, the resource setting (resource setting) for interference measurement corresponding to (or associated with) the CSI reporting configuration information includes multiple (non-periodic) resource sets. For example, the CSI-ResourceConfig configured by the csi-IM-ResourcesForInterference parameter of CSI-ReportConfig includes multiple resource sets (e.g., CSI-IM-ResourceSet);

Optionally, the resource setting (resource setting) for channel measurement corresponding to (or associated with) the CSI reporting configuration information includes a non-periodic resource set. For example, the CSI-ResourceConfig configured by the resourcesForChannelMeasurement parameter of CSI-ReportConfig includes a resource set (e.g., NZP-CSI-RS-ResourceSet). For example, the resource type of the resource setting is non-periodic;

[0134] ●The UE is configured with the CSI aperiodic trigger state list parameter (CSI-AperiodicTriggerStateList).

[0135] Optionally, the second sub-configuration includes / is associated with / corresponds to / indicates multiple second resource parameters. Optionally, the CSI reporting configuration information corresponds to multiple resource sets (for interference measurement). Optionally, the number of multiple resource sets (for interference measurement) corresponding to the CSI reporting configuration information is equal to the number of multiple second resource parameters. Optionally, the multiple resource sets for interference measurement corresponding to the CSI reporting configuration information are in one-to-one correspondence with the multiple second resource parameters. Optionally, the one-to-one correspondence may be a one-to-one correspondence in order. Optionally, the order / position may be determined based on the (sequential) order / position of multiple resource sets for interference measurement in the resource setting and / or the (sequential) order / position of multiple first resource parameters in the corresponding list. For example, the CSI reporting configuration information (in the corresponding resource setting) includes 3 resource sets for interference measurement, namely {CSI-IM#1, CSI-IM#2, CSI-IM#3, CSI-IM#4}, {CSI-IM#5, CSI-IM#6}, {CSI-IM#7, CSI-IM#8, CSI-IM#9, CSI-IM#10}, and the 3 second resource parameters respectively indicate {CSI-IM#1, CSI-IM#4}, {CSI-IM#6}, {CSI-IM#9, CSI-IM#10}. The 3 resource sets correspond to the 3 first resource parameters in order. Optionally, the method of using (each) second resource parameter is as described above.

[0136] Optionally, (for a CSI report) (only) one of the multiple (non-periodic) resource sets in the resource setting is associated with a trigger state. Optionally, each trigger state of each resource setting may be configured with parameters for selecting a resource set in the resource setting. Optionally, the UE receives trigger signaling (e.g., DCI format) for non-periodic CSI reporting. Optionally, the trigger signaling may indicate a trigger state. The UE may determine one of the multiple (non-periodic) resource sets in the resource setting based on the parameters associated with the trigger state (or, the parameters configured for the trigger state). Optionally, the selected / indicated (non-periodic) resource set determines the reference signal resource (for interference measurement) based on the corresponding second resource parameter. Optionally, for the corresponding (or, selected) resource set, the method for using the second resource parameter is as described above.

[0137] Optionally, the second sub-configuration includes / is associated with / corresponds to / indicates a second resource parameter and / or a second resource set indication parameter. Optionally, the CSI reporting configuration information corresponds to multiple resource sets (for interference measurement). Optionally, the second sub-configuration includes / is associated with / corresponds to / indicates a second resource set indication parameter. Optionally, the second resource set indication parameter indicates / selects one of the multiple resource sets (for interference measurement) corresponding to the CSI reporting configuration information. Optionally, the second sub-configuration includes / is associated with / corresponds to / indicates a second resource parameter. Optionally, the second resource parameter is used to indicate a reference signal (for interference measurement) corresponding to the CSI reporting configuration information. Optionally, for the corresponding (or selected) resource set, the method for using the second resource parameter is as described above. For example, the CSI reporting configuration information (in the corresponding resource setting) includes 3 resource sets for interference measurement, namely {CSI-IM#1, CSI-IM#2, CSI-IM#3, CSI-IM#4}, {CSI-IM#5, CSI-IM#6}, {CSI-IM#7, CSI-IM#8, CSI-IM#9, CSI-IM#10}, a second resource set indication parameter indicating {0}, and a second resource parameter indicating {CSI-IM#1, CSI-IM#4}. Here, if the second resource set indication parameter indicates 0 (or, indicates the first state), it means that the first resource set is indicated; if it indicates 1 (or, indicates the second state), it means that the second resource set is indicated, and so on. Here, the second resource parameter can be used to indicate the resources (e.g., reference signal resources) in the resource set indicated by the second resource set indication parameter. For the method of using the second resource parameter, see above.

[0138] Optionally, the mapping relationship between the third resource parameter and the resource indicated by it may be determined according to one of the following methods:

[0139] Method 1

[0140] The third resource parameter is a list. Optionally, one item (or each item) of the list indicates a resource ID (for example, a CSI-RS resource ID). Optionally, the resource corresponding to the resource ID belongs to the resource set for interference measurement corresponding to the CSI reporting configuration information (for example, NZP-CSI-RS-ResourceSet). For example, the resource set for interference measurement corresponding to the CSI reporting configuration information is {CSI-RS#1, CSI-RS#3, CSI-RS#4, CSI-RS#7}, and the third resource parameter indicates {#1, #7}, then the interference measurement resource corresponding to the second sub-configuration is {CSI-RS#1, CSI-RS#7}. The terminal device uses the reference signal resource corresponding to the resource ID indicated by the list for interference measurement (instead of using all reference signal resources in the resource set for interference measurement corresponding to the CSI reporting configuration information for interference measurement).

[0141] Method 2

[0142] The third resource parameter is a list. Optionally, one item (or each item) of the list indicates the index of a resource in a resource set. For example, the first resource of the resource set is index 0, the second resource of the resource set is index 1, and so on. Optionally, the resource set refers to / includes a resource set for interference measurement corresponding to the CSI reporting configuration information (for example, NZP-CSI-RS-ResourceSet). For example, the resource set for interference measurement corresponding to the CSI reporting configuration information is {CSI-RS#1, CSI-RS#3, CSI-RS#4, CSI-RS#7}, and the third resource parameter indicates {0, 2}, then the interference measurement reference signal resource corresponding to the second sub-configuration is {CSI-RS#1, CSI-RS#4}. The terminal device uses the resources indicated by the list for interference measurement (instead of using all resources in the resource set for interference measurement corresponding to the CSI reporting configuration information for interference measurement).

[0143] The above method can clarify the mapping relationship between the third resource parameter and the corresponding resource, and improve the reliability of the communication system.

[0144] Optionally, the resource for interference measurement corresponding to the second sub-configuration of the first CSI parameter refers to the resource for interference measurement indicated by the first resource parameter of the second sub-configuration corresponding to the first CSI parameter (for example, a reference signal resource). Taking the first CSI parameter as CRI as an example, there is a mapping relationship between CRI and the resource for interference measurement indicated by the third resource parameter. The mapping relationship can be determined by at least one of the following methods:

[0145] Method 1

[0146] CRI is determined based on the order / position of the resources for interference measurement indicated by the third resource parameter in the resource set for interference measurement corresponding to the CSI reporting configuration information. Optionally, the value k corresponding to CRI represents the k+1th resource in the resource set for interference measurement corresponding to the CSI reporting configuration information indicated by the third resource parameter. For example, the resource set for interference measurement corresponding to the CSI reporting configuration information is {CSI-RS#1, CSI-RS#3, CSI-RS#4, CSI-RS#7}, and the third resource parameter indicates CSI-RS#4 and CSI-RS#1, then k=0 corresponds to CSI-RS#1; k=1 corresponds to CSI-RS#4.

[0147] Method 2

[0148] CRI is determined based on the order / position of the resources for interference measurement indicated by the third resource parameter in the third resource parameter. Optionally, the value k corresponding to CRI represents the resources indicated by the k+1th item of the third resource parameter. For example, the resource set for interference measurement corresponding to the CSI reporting configuration information is {CSI-RS#1, CSI-RS#3, CSI-RS#4, CSI-RS#7}, and the third resource parameter indicates CSI-RS#4 and CSI-RS#1 (for example, CSI-RS#4 corresponds to the first item of the third resource parameter; CSI-RS#1 corresponds to the second item of the third resource parameter), then k=0 corresponds to CSI-RS#4; k=1 corresponds to CSI-RS#1.

[0149] Method 3

[0150] CRI is determined based on the order / position (e.g., order / position of size) of the resource IDs used for interference measurement indicated by the third resource parameter. For example, from small to large or from large to small. Optionally, the value k corresponding to CRI represents the resource with the k+1th largest ID (or, the k+1th smallest) in the resources indicated by the third resource parameter. Taking the example that the value k corresponding to CRI represents the resource with the k+1th smallest ID in the resources indicated by the third resource parameter, the resource set for interference measurement corresponding to the CSI reporting configuration information is {CSI-RS#3, CSI-RS#1, CSI-RS#4, CSI-RS#7}, and the third resource parameter indicates {CSI-RS#3, CSI-RS#1, CSI-RS#4}, then k=0 corresponds to CSI-RS#1; k=1 corresponds to CSI-RS#3; k=2 corresponds to CSI-RS#4.

[0151] The above method can clarify the mapping relationship between CRI (or k) and the corresponding resources, and improve the reliability of the communication system. Based on the above method, a CRI value can be associated with a resource for channel measurement and at least one resource for interference resources. Different CRI values ​​can be associated with different resource pairs, wherein each resource pair may include a resource for channel measurement and one or more resources for interference resources. Thus, the terminal device performs channel measurement and interference measurement on the resources in different resource pairs, selects at least one resource pair, and reports the corresponding information to the base station. Clarifying the mapping relationship between the resources indicated by the third resource parameter (and / or the resources indicated by the first resource parameter and / or the resources indicated by the second resource parameter) and the CRI can avoid different understandings of the reported information between the terminal device and the base station.

[0152] Optionally, when the second condition is met, the second sub-configuration includes / is associated with / corresponds to / indicates at least one of the following: a plurality of third resource parameters; or a third resource parameter and / or a third resource set indication parameter. Optionally, the second condition includes at least one of the following:

Optionally, the resource set may be used for channel measurement and / or for interference measurement. Optionally, the resource setting (resource setting) for interference measurement corresponding to (or associated with) the CSI reporting configuration information includes multiple (non-periodic) resource sets. For example, the CSI-ResourceConfig configured by the nzp-CSI-RS-ResourcesForInterference parameter of CSI-ReportConfig includes multiple resource sets (e.g., NZP-CSI-RS-ResourceSet);

[0154] ●The CSI reporting configuration information corresponds to a non-periodic resource set. Optionally, the resource set may be used for channel measurement and / or for interference measurement. Optionally, the resource setting (resource setting) for channel measurement corresponding to (or associated with) the CSI reporting configuration information includes a non-periodic resource set. For example, the CSI-ResourceConfig configured by the resourcesForChannelMeasurement parameter of CSI-ReportConfig includes a resource set (e.g., NZP-CSI-RS-ResourceSet). For example, the resource type of the resource setting is non-periodic;

[0155] ●The UE is configured with the CSI aperiodic trigger state list parameter (CSI-AperiodicTriggerStateList).

[0156] Optionally, the second sub-configuration includes / is associated with / corresponds to / indicates multiple third resource parameters. Optionally, the CSI reporting configuration information corresponds to multiple resource sets (for interference measurement). Optionally, the number of multiple resource sets (for interference measurement) corresponding to the CSI reporting configuration information is equal to the number of multiple third resource parameters. Optionally, the multiple resource sets for interference measurement corresponding to the CSI reporting configuration information correspond one-to-one to the multiple third resource parameters. Optionally, the one-to-one correspondence may be one-to-one correspondence in order. Optionally, the order / position may be determined based on the (sequential) order / position of multiple resource sets for interference measurement in the resource setting and / or the (sequential) order / position of multiple third resource parameters in the corresponding list. For example, the CSI reporting configuration information (in the corresponding resource setting) includes 3 resource sets for interference measurement, namely {CSI-RS#1, CSI-RS#2, CSI-RS#3, CSI-RS#4}, {CSI-RS#5, CSI-RS#6}, {CSI-RS#7, CSI-RS#8, CSI-RS#9, CSI-RS#10}, and the 3 third resource parameters respectively indicate {CSI-RS#1, CSI-RS#4}, {CSI-RS#6}, {CSI-RS#9, CSI-RS#10}. The 3 resource sets correspond to the 3 third resource parameters in order. Optionally, the method of using (each) third resource parameter is as described above.

[0157] Optionally, (for a CSI report) (only) one of the multiple (non-periodic) resource sets in the resource setting is associated with a trigger state. Optionally, each trigger state of each resource setting may be configured with parameters for selecting a resource set in the resource setting. Optionally, the UE receives trigger signaling (e.g., DCI format) for non-periodic CSI reporting. Optionally, the trigger signaling may indicate a trigger state. The UE may determine one of the multiple (non-periodic) resource sets in the resource setting based on the parameters associated with the trigger state (or, the parameters configured for the trigger state). Optionally, the selected / indicated (non-periodic) resource set determines the reference signal resource (for interference measurement) based on the corresponding first resource parameter. Optionally, for the corresponding (or, selected) resource set, the method for using the third resource parameter is as described above.

[0158] Optionally, the second sub-configuration includes / is associated with / corresponds to / indicates a third resource parameter and / or a third resource set indication parameter. Optionally, multiple resource sets (for interference measurement) corresponding to the CSI reporting configuration information. Optionally, the second sub-configuration includes / is associated with / corresponds to / indicates a third resource set indication parameter.

Optionally, the third resource parameter is used to indicate a reference signal (for channel measurement) corresponding to the CSI reporting configuration information. Optionally, for the corresponding (or selected) resource set, the method for using the third resource parameter is as described above. For example, the CSI reporting configuration information (in the corresponding resource setting) includes 3 resource sets for interference measurement, namely {CSI-RS#1, CSI-RS#2, CSI-RS#3, CSI-RS#4}, {CSI-RS#5, CSI-RS#6}, {CSI-RS#7, CSI-RS#8, CSI-RS#9, CSI-RS#10}, a third resource set indication parameter indicating {0}, and a third resource parameter indicating {CSI-RS#1, CSI-RS#4}. Here, if the third resource set indication parameter indicates 0 (or, indicates the first state), it means that the first resource set is indicated; if it indicates 1 (or, indicates the second state), it means that the second resource set is indicated, and so on. Here, the third resource parameter can be used to indicate the resources (e.g., reference signal resources) in the resource set indicated by the third resource set indication parameter. For the method of using the third resource parameter, see above.

[0159] Optionally, the second sub-configuration includes (one or more) first resource parameters, and the second sub-configuration includes (one or more) second resource parameters and / or (one or more) third resource parameters. Below, a method for mapping channel measurement resources and interference measurement resources is provided so that the terminal device uses the correct resource combination for measurement and calculation of CSI parameters, thereby improving the reliability of the communication system. Optionally, the resource indicated by the first resource parameter and the resource indicated by the second resource parameter are associated based on at least one of the following:

[0160] ● The order / position of the resources indicated by the first resource parameter. For example, the order / position of the resources indicated by the first resource parameter in the indication parameter. For example, the order / position of the resources indicated by the first resource parameter in the resource set corresponding to the CSI reporting configuration information. For example, the order of the resource IDs indicated by the first resource parameter (from small to large or from large to small).

[0161] ● The order / position of the resources indicated by the second resource parameter. For example, the order / position of the resources indicated by the second resource parameter in the indication parameter. For example, the order / position of the resources indicated by the second resource parameter in the resource set corresponding to the CSI reporting configuration information. For example, the order of the resource IDs indicated by the second resource parameter (from small to large or from large to small).

[0162] Optionally, the resource indicated by the first resource parameter and the resource indicated by the third resource parameter are associated based on at least one of the following:

[0163] ● The order / position of the resources indicated by the first resource parameter. For example, the order / position of the resources indicated by the first resource parameter in the indication parameter. For example, the order / position of the resources indicated by the first resource parameter in the resource set corresponding to the CSI reporting configuration information. For example, the order of the resource IDs indicated by the first resource parameter (from small to large or from large to small).

[0164] ● The order / position of the resources indicated by the third resource parameter. For example, the order / position of the resources indicated by the third resource parameter in the indication parameter. For example, the order / position of the resources indicated by the third resource parameter in the resource set corresponding to the CSI reporting configuration information. For example, the order of the resource IDs indicated by the third resource parameter (from small to large or from large to small).

[0165] For example, the CSI reporting configuration information (in the corresponding resource setting) includes a resource set {CSI-RS#1, CSI-RS#2, CSI-RS#3, CSI-RS#4} for channel measurement, and the first resource parameter indicates {CSI-RS#1, CSI-RS#4}; the CSI reporting configuration information (in the corresponding resource setting) includes a resource set {CSI-IM#1, CSI-IM#2, CSI-IM#3, CSI-IM#4} for interference measurement, and the second resource parameter indicates {CSI-IM#1, CSI-IM#4}. Here, based on the corresponding order / position of the resources indicated by the first resource parameter in the first resource parameter, CSI-RS#1 is associated with CSI-IM#1; and CSI-RS#4 is associated with CSI-IM#4.

[0166] Optionally, the number of first resource parameters is the same as the number of second resource parameters or third resource parameters. Optionally, if the second sub-configuration includes (one or more) first resource parameters, and the second sub-configuration includes (one or more) second resource parameters and / or (one or more) third resource parameters, the number of first resource parameters is the same as the number of second resource parameters or third resource parameters. Optionally, the first resource parameter and the second resource parameter or the third resource parameter are in one-to-one correspondence. Optionally, if the second sub-configuration includes (one or more) first resource parameters, and the second sub-configuration includes (one or more) second resource parameters and / or (one or more) third resource parameters, the (one or more) first resource parameters and (one or more) second resource parameters or (one or more) third resource parameters are in one-to-one correspondence. Optionally, if the second sub-configuration includes (one or more) first resource parameters, and the second sub-configuration includes (one or more) second resource parameters and / or (one or more) third resource parameters, the resources indicated by the first resource parameter and the resources (associated) with the second resource parameter or the third resource parameter are in one-to-one correspondence.

[0167] For example, the CSI reporting configuration information (in the corresponding resource setting) includes 3 resource sets for channel measurement, namely {CSI-RS#1, CSI-RS#2, CSI-RS#3, CSI-RS#4}, {CSI-RS#5, CSI-RS#6}, {CSI-RS#7, CSI-RS#8, CSI-RS#9, CSI-RS#10}, and the 3 first resource parameters respectively indicate {CSI-RS#1, CSI-RS#4}, {CSI-RS#6}, {CSI-RS#9, CSI-RS#10}.}; The CSI reporting configuration information (in the corresponding resource setting) includes 3 resource sets for interference measurement, namely {CSI-IM#1, CSI-IM#2, CSI-IM#3, CSI-IM#4}, {CSI-IM#5, CSI-IM#6}, {CSI-IM#7, CSI-IM#8, CSI-IM#9, CSI-IM#10}, and the 3 second resource parameters respectively indicate {CSI-IM#1, CSI-IM#4}, {CSI-IM#6}, {CSI-IM#9, CSI-IM#10}. Here, the number of resource sets used for channel measurement is equal to the number of resource sets used for interference measurement. Here, the number of multiple resource sets for channel measurement is equal to the number of multiple resource sets for interference measurement. Here, the number of resources in the resource set for channel measurement is equal to the number of resources in the resource set for interference measurement. Optionally, the resources in the resource set used for channel measurement and the resources in the resource set used for interference measurement are associated based on resource order / position (or, one-to-one correspondence).

[0168] Optionally, if the first CSI parameter corresponding to the resource for channel measurement of the second sub-configuration is the same as the first CSI parameter corresponding to the resource for interference measurement of the second sub-configuration (for example, the value of the first CSI parameter is the same, or the value of CRI is the same), then the resource for channel measurement is associated with the resource for interference measurement. For example, the resource for channel measurement is associated with the resource for interference measurement, which means that the CQI corresponding to the first CSI parameter (for example, CRI) is calculated based on the resource for channel measurement and (the measurement result of) the resource for channel measurement.

[0169] The quasi-co-location relationship between the channel measurement resources and the interference measurement resources is described below, so that the terminal device uses the correct spatial parameters to measure the corresponding resource combination and calculate the CSI parameters, thereby improving the reliability of the communication system. Optionally, the resources used for channel measurement and the resources used for interference measurement are quasi-co-located (e.g., type D quasi-co-located). Optionally, the resources used for channel measurement and the associated resources for interference measurement are quasi-co-located (e.g., type D quasi-co-located). Optionally, the resources used for channel measurement and the resources used for interference measurement are quasi-co-located per resource (resource-wise) (e.g., type D quasi-co-located). Optionally, the resources used for channel measurement (e.g., NZP CSI-RS resources) and the resources used for interference measurement (e.g., NZP CSI-RS resources or CSI-IM resources) are quasi-co-located (e.g., type D quasi-co-located). Optionally, the UE may assume that the associated resources used for channel measurement and the resources used for interference measurement are quasi-co-located (e.g., type D quasi-co-located). Optionally, the UE may assume that the associated resources for channel measurement (e.g., NZP CSI-RS resources) and the associated resources for interference measurement (e.g., NZP CSI-RS resources or CSI-IM resources) are quasi-co-located (e.g., type D quasi-co-located).

[0170] For example, the CSI reporting configuration information (in the corresponding resource setting) includes a resource set {CSI-RS#1, CSI-RS#2, CSI-RS#3, CSI-RS#4} for channel measurement, a first resource parameter indication {CSI-RS#1, CSI-RS#4}, and the mapping relationship between CRI and the resource for channel measurement is based on the resource order / position of the resource set for channel measurement in the CSI reporting configuration information; and the CSI reporting configuration information (in the corresponding resource setting) includes a resource set {CSI-IM#1, CSI-IM#2, CSI-IM#3, CSI-IM#4} for interference measurement, a second resource parameter indication {CSI-IM#1, CSI-IM#3}, and the mapping relationship between CRI and the resource for interference measurement is based on the resource order / position of the resource set for interference measurement in the CSI reporting configuration information. In this case, CRI can be 0 or 1. When CRI is equal to 0, the resource corresponding to the CRI for channel measurement is CSI-RS#1; the resource corresponding to the CRI for interference measurement is CSI-IM#1. When CRI is equal to 1, the resource corresponding to the CRI for channel measurement is CSI-RS#4; the resource corresponding to the CRI for interference measurement is CSI-IM#3. CSI-RS#1 and CSI-IM#1 are about type D quasi-co-location; or, the UE can consider CSI-RS#1 and CSI-IM#1 to be about type D quasi-co-location. CSI-RS#4 and CSI-IM#3 are about type D quasi-co-location; or, the UE can consider CSI-RS#4 and CSI-IM#3 to be about type D quasi-co-location.

[0171] Here, by explicitly indicating the sub-configuration's resources for channel measurement and / or interference measurement (for example, by indicating the resources for channel measurement and / or the resources for interference measurement through at least one of the first resource parameter, the second resource parameter, and the third resource parameter), the terminal device can correctly use the corresponding resources and correctly calculate the CSI parameters of the sub-configuration, thereby improving the reliability of the communication system.

[0172] In addition, the following continues to describe a method for implicitly determining the resources for interference measurement of a sub-configuration (for example, determining the resources for channel measurement and / or the resources for interference measurement based on a first resource parameter) so that the terminal device can correctly use the corresponding resources and correctly calculate the CSI parameters of the sub-configuration, thereby improving the reliability of the communication system.

[0326] The above describes a method for determining the time resources of the CPU occupied by CSI reporting (e.g., CSI reporting for CSI prediction). In the case of cell DTX and / or DRX (e.g., UE DRX), the method can use corresponding conditions to limit the CSI measurement opportunities (e.g., CSI-RS opportunities, or CSI opportunities, or CSI measurement opportunities) used to determine the time resources occupied by CSI reporting to CSI measurement opportunities in the cell DTX activation time and / or CSI measurement opportunities in the DRX activation time, avoiding errors caused by using CSI measurement opportunities in the cell DTX inactive time and / or DRX inactive time to determine the time resources occupied by the CPU (e.g., the UE does not receive CSI-RS in the cell DTX inactive time and / or DRX inactive time), thereby ensuring the accuracy of CSI reporting and improving the performance of the communication system. Optionally, the method can utilize corresponding conditions to limit the CSI measurement opportunities (for example, CSI-RS opportunities, or CSI opportunities) used to determine the time resources occupied by CSI reporting to CSI measurement opportunities in the same cell DTX activation time and / or CSI measurement opportunities in the same DRX activation time, thereby avoiding channel differences (resulting in inaccurate CSI reporting) caused by continuous CSI measurement opportunities spanning multiple cell DTX activation times (time periods) or spanning multiple DRX activation times (time periods), thereby improving the accuracy of CSI reporting and further improving the performance of the communication system.

For example, the first resource is determined by the CSI-RS and / or CSI-IM resources corresponding to (all) sub-configurations corresponding to the reported CSI (or, CSI report). For example, the first resource can be determined based on the CSI-RS and / or CSI-IM resources corresponding to the second sub-configuration (for example, N sub-configurations), or the CSI-RS and / or CSI-IM resources corresponding to multiple first sub-configurations (for example, L sub-configurations).

[0346] Optionally, for a sub-configuration, the CSI-RS and / or CSI-IM resources are determined based on at least one of the first reference resource parameter, the second reference resource parameter, and the third reference resource parameter indicated by the second sub-configuration. For example, for a sub-configuration, the CSI-RS resources used for channel measurement are indicated based on the first reference resource parameter. For example, for a sub-configuration, the CSI-IM resources used for interference measurement are indicated based on the second reference resource parameter, or are determined based on the resources indicated by the first reference resource parameter and the resource set for interference measurement corresponding to the CSI report. For example, for a sub-configuration, the CSI-RS resources used for interference measurement are indicated based on the third reference resource parameter, or are determined based on the resources indicated by the first reference resource parameter and the resource set for interference measurement corresponding to the CSI report.

[0366] In this embodiment, the term "CSI-RS" may be interchangeable with "NZP CSI-RS".

[0367] The method provided in Example 6 can clarify the time domain restriction of CSI reporting to avoid the CSI-RS resources corresponding to different sub-configurations being too far apart in the time domain (resulting in the CSI between different sub-configurations being incomparable), so that the CSI corresponding to different sub-configurations can be compared more accurately, thereby improving the accuracy of CSI reporting and thereby improving the performance of the communication system.

[0368] Embodiment 7

[0369] The UE may be configured with a CSI reporting configuration (e.g., CSI-ReportConfig), wherein the CSI reporting configuration may be associated with a CSI resource setting. Optionally, the CSI resource setting may include a CSI resource setting for channel measurement and / or a CSI resource setting for interference measurement. Optionally, the CSI resource setting may correspond to / include one or more resource sets. Optionally, the CSI resource setting may correspond to / include at least one of a CSI-RS resource, a CSI-IM resource, and an SSB resource. Optionally, a resource set may include several resources. Optionally, a resource set may include / correspond to at least one of a CSI-RS resource, a CSI-IM resource, and an SSB resource. For example, the UE may determine and / or report the CSI associated with / corresponding to the CSI reporting configuration based on measurements of resources in the CSI resource setting associated with the CSI reporting configuration.

[0370] In some cases, the UE may be configured with several serving cells. Optionally, one / each of the several serving cells may be configured and / or activated with cell DTX. For example, among the several serving cells configured with the UE, the cell DTX of some cells is activated, while the cell DTX of other cells is not activated. The UE behavior related to CSI measurement / CSI reporting will be affected by cell DTX. It is necessary to clarify which serving cells' DTX is activated for the resource measurement and / or CSI reporting behavior associated with the CSI reporting configuration. Note that the cell where the CSI reporting configuration is located and the cell where the CSI resource setting associated with the CSI reporting configuration is located may be the same or different. For example, the CSI reporting configuration may include a high-level parameter (e.g., carrier) for indicating the cell where the associated CSI resource setting is located. For example, the UE may determine the cell where the corresponding measurement resource is located based on the high-level parameter (e.g., carrier) that may be included in the CSI reporting configuration. For example, the UE may determine which cell to measure on based on the high-level parameter (e.g., carrier) that may be included in the CSI reporting configuration. For example, when the CSI reporting configuration does not include a high-level parameter (e.g., carrier), the cell where the corresponding / associated CSI resource setting is located is the same as the cell where the CSI reporting configuration is located. For example, when the CSI reporting configuration may not include a high-level parameter (e.g., carrier), the associated CSI resource setting is located in the cell where the CSI reporting configuration is located. Since whether the cell DTX is activated is determined individually for each cell, the following method specifies that when the cell DTX of the cell where the CSI resource setting associated with the CSI reporting configuration is located (or, the cell where the measurement resource is located) is activated, the resource measurement and / or CSI reporting behavior corresponding to the CSI reporting configuration will be affected by the cell DTX. In this document, the term "CSI" and the term "CSI value" are interchangeable. In this document, "CSI resource settings associated with CSI reporting configuration" may be interchanged with the term "CSI resource settings corresponding to CSI reporting configuration" or "resources associated with CSI reporting configuration" or "measurement associated with CSI reporting configuration" or "measurement resources associated with CSI reporting configuration" or "resources for channel measurement and / or interference measurement associated with CSI reporting configuration" or "resources for channel measurement associated with CSI reporting configuration". In this document, "cell DTX is activated" may be interchanged with the term "cell DTX is configured" or "cell DTX is configured and / or activated".

[0371] Optionally, if a higher-layer parameter for channel measurement (e.g., timeRestrictionForChannelMeasurements) in a CSI reporting configuration (e.g., CSI-ReportConfig) is set to "Configured", the UE determines the channel measurement for calculating the CSI (reported in uplink time slot n) based (only) on the CSI-RS opportunity associated with the CSI resource setting (associated with the CSI reporting configuration). Optionally, calculating the CSI may be calculating the CQI. Optionally, the CSI-RS may be an NZP CSI-RS. Optionally, the CSI-RS opportunity may be a CSI-RS transmission opportunity. Here, the CSI-RS opportunity refers to / includes / corresponds to at least one of the following:

[0372] ●The nearest CSI-RS opportunity;

[0373] ● CSI-RS opportunity no later than the CSI reference resource;

[0374] ●CSI-RS opportunities during DRX activation time;

[0375] ● When DRX is configured, CSI-RS opportunities during the DRX activation time;

[0376] ●CSI-RS opportunities within the cell DTX activation time;

[0377] ●When cell DTX is activated on a serving cell with the CSI resource Setting linkedto the CSI-ReportConfig, the CSI-RS opportunities within the cell DTX activation time (of the serving cell).

[0378] Here, n may represent a timeslot number. Optionally, n≥0. Optionally, DRX may be UE DRX or C-DRX.

[0379] Optionally, if a higher-layer parameter for interference measurement (e.g., timeRestrictionForInterferenceMeasurements) in a CSI reporting configuration (e.g., CSI-ReportConfig) is set to "Configured", the UE determines interference measurement for calculating CSI (reported in uplink time slot n) based (only) on the CSI-IM and / or CSI-RS opportunities associated with the CSI resource setting (associated with the CSI reporting configuration). Optionally, calculating CSI may be calculating CQI. Optionally, the CSI-RS may be an NZP CSI-RS. Optionally, the CSI-IM opportunity may be a CSI-IM transmission opportunity. Optionally, the CSI-RS opportunity may be a CSI-RS transmission opportunity. Here, CSI-IM and / or CSI-RS opportunities refer to / include / correspond to at least one of the following:

[0380] ●The nearest CSI-IM and / or CSI-RS opportunity;

[0381] ● CSI-IM and / or CSI-RS opportunities no later than the CSI reference resource;

[0382] ●CSI-IM and / or CSI-RS opportunities during DRX activation time;

[0383] ● When DRX is configured, CSI-IM and / or CSI-RS opportunities during the DRX activation time;

[0384] ● CSI-IM and / or CSI-RS opportunities within the cell DTX activation time;

[0385] ●If cell DTX is activated on a serving cell with the CSI resource Setting linkedto the CSI-ReportConfig, CSI-IM and / or CSI-RS opportunities within the cell DTX activation time (of the serving cell).

[0386] Here, n may represent a timeslot number. Optionally, n≥0. Optionally, DRX may be UE DRX or C-DRX.

[0387] Optionally, for a CSI reporting configuration in which the associated high-level parameter related to the reporting quantity (e.g., reportQuantity) includes at least 'RI', and (if) the CSI resource associated with the CSI reporting configuration is set on a serving cell in which cell DTX is activated, the UE reports a CSI report (only) when at least one CSI-IM and / or CSI-RS opportunity is received; otherwise the UE discards the CSI report. Optionally, the CSI-IM and / or CSI-RS opportunity refers to / corresponds to / includes (each) CSI-IM and / or CSI-RS resource or semi-persistent CSI-IM and / or CSI-RS resource for channel measurement and / or interference measurement. Optionally, the CSI-RS opportunity refers to / corresponds to / includes (each) CSI-RS opportunity for a periodic CSI-RS resource or semi-persistent CSI-RS resource for channel measurement and / or interference measurement. Optionally, the CSI-RS opportunity may be a CSI-RS transmission opportunity. Optionally, the CSI-IM opportunity may be a CSI-IM transmission opportunity. Optionally, the CSI-IM and / or CSI-RS opportunity refers to / corresponds to / includes at least one of the following:

[0388] ●The nearest CSI-IM and / or CSI-RS opportunity;

[0389] ● CSI-IM and / or CSI-RS opportunities no later than the CSI reference resource;

[0390] ●CSI-IM and / or CSI-RS opportunities during DRX activation time;

[0391] ● When DRX is configured, CSI-IM and / or CSI-RS opportunities during the DRX activation time;

[0392] ● CSI-IM and / or CSI-RS opportunities within the cell DTX activation time;

[0393] ●If cell DTX is activated on the serving cell with the CSI resource Setting linked to the CSI-ReportConfig, the CSI-IM and / or CSI-RS opportunities within the cell DTX activation time (of the serving cell).

[0394] Optionally, DRX can be UE DRX or C-DRX.

[0395] Optionally, if the CSI resource associated with the CSI reporting configuration is set in a serving cell in which the cell DTX is activated, the UE does not receive (or does not expect to receive) periodic CSI-RS and / or semi-persistent CSI-RS during the inactive time of the cell DTX (of the serving cell). Optionally, the periodic CSI-RS and / or semi-persistent CSI-RS are configured by the CSI reporting configuration, and the high-level parameters related to the reporting quantity (e.g., reportQuantity) associated with the CSI reporting configuration include at least 'RI'.

[0396] Optionally, if cell DTX is activated for a serving cell and the CSI resource associated with the CSI reporting configuration is set in the serving cell, the high-level parameters related to the reporting quantity (e.g., reportQuantity) associated with the CSI reporting configuration include at least 'RI', and the most recent CSI measurement occasion of semi-persistent CSI-RS resource or periodic CSI-RSresource (associated with the CSI reporting configuration) occurs in active periods of cell DTX (of the serving cell).

[0397] The method provided in Example 7 conditionally limits that when the cell DTX of the service cell where the CSI resource setting associated with / corresponding to the CSI reporting configuration is located (or the service cell where the measurement resource is located) is activated, the corresponding measurement / reporting of the CSI reporting configuration will be based on the cell DTX, which clarifies the UE behavior associated with the CSI reporting configuration and improves the reliability of the communication system.
