Description

Technical Field

[0001] This disclosure relates generally to wireless communication, and more specifically to methods, apparatus and systems for measuring and reporting channel state information in wireless communication. Background Technology

[0002] Fifth-generation (5G) New Radio (NR) networks will support Ultra-Reliable and Low-Latency Communication (URLLC) applications, such as intelligent vehicle control, drone control, robotic surgery, and machine-type communications (MTC) applications like industrial automation. These applications require new solutions to meet the demand for lower latency. Given the low latency and high reliability of URLLC services, terminals or user equipment (UEs) need to provide more accurate and timely feedback of Channel State Information (CSI) to the base station so that the base station can perform more appropriate link adaptation to ensure URLLC service requirements are met.

[0003] CSI feedback can include statistical information such as the mean and variance of Channel Quality Information (CQI). To obtain this statistical information, the UE needs to perform measurements on multiple CSI Reference Signals (CSI-RS) to obtain multiple observation examples for calculating the statistics. CSI can also be obtained based on the decoding state of the Physical Downlink Shared Channel (PDSCH). In this case, the UE needs to calculate the CSI based on PDSCH reception. However, given the statistical information calculation and other 5G requirements, there is currently no existing solution regarding how the UE can measure more accurate channel state information based on downlink signals or channels.

[0014] Various exemplary embodiments of this disclosure are described below with reference to the accompanying drawings to enable those skilled in the art to make and use this disclosure. It will be apparent to those skilled in the art that, upon reading this disclosure, various changes or modifications can be made to the examples described herein without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the exemplary embodiments and applications described and illustrated herein. Furthermore, the specific order and / or hierarchy of steps in the methods disclosed herein are merely exemplary methods. Based on design preferences, the specific order or hierarchy of steps in the disclosed methods or processes can be rearranged while remaining within the scope of this disclosure. Therefore, those skilled in the art will understand that the methods and techniques disclosed herein present various steps or actions in an exemplary order, and unless otherwise expressly stated, this disclosure is not limited to the specific order or hierarchy presented.

[0015] A typical wireless communication network includes one or more base stations (usually referred to as "BS") and one or more wireless user equipments (usually referred to as "UE"). Each base station provides geographic radio coverage, and the one or more wireless user equipments can transmit and receive data within the radio coverage. In a wireless communication network, the BS and UE can communicate with each other via communication links (e.g., via downlink (DL) radio frames from the BS to the UE or via uplink (UL) radio frames from the UE to the BS).

[0016] In the current New Radio (NR) standard, feedback of aperiodic Channel State Information (CSI) can only be triggered by the Physical Downlink Control Channel (PDCCH) carrying the UL Grant and transmitted on the Physical Uplink Shared Channel (PUSCH) scheduled by the UL Grant. In this mode, if there is no UL Shared Channel (SCH) to transmit on, the BS must transmit the PDCCH carrying the UL Grant to trigger aperiodic CSI feedback. This can lead to PDCCH congestion. One solution is that the PDCCH carrying the DL Grant can trigger aperiodic CSI feedback, and the DL Grant can simultaneously schedule the Physical Downlink Shared Channel (PDSCH). This enhances the triggering of aperiodic CSI feedback. When the BS has a PUSCH to schedule and the terminal needs to feedback CSI, the UL Grant can trigger aperiodic CSI feedback. When the BS has a PDSCH to schedule and the terminal needs to provide channel state information feedback, the DL Grant can trigger aperiodic channel state information feedback.

[0017] This disclosure provides a method and system for a UE to measure CSI based on determined measurement resources and / or other configurations, and to send a CSI report as feedback to the BS on the CSI feedback resources desired by the BS. When the resources used for PDSCH and CSI measurements overlap, the UE can perform CSI measurements through rate matching without affecting PDSCH reception.

[0018] The methods disclosed in this teaching can be implemented in a wireless communication network, wherein the BS and UE can communicate with each other via a communication link (e.g., via downlink radio frames from the BS to the UE or via uplink radio frames from the UE to the BS). In various embodiments, the BS in this disclosure may be referred to as the network side and may include or be implemented as a next-generation node B (gNB), an E-UTRAN Node B (eNB), a transmission / reception point (TRP), an access point (AP), an AP MLD (AP Multi-link Device), a non-ground receiving point for satellite / balloon / UAV communication, a radio transceiver in a vehicle for a vehicle-to-vehicle (V2V) wireless network, etc.; while the UE in this disclosure may be referred to as a terminal and may include or be implemented as a mobile station (MS), a station (STA), a non-AP MLD, ground equipment for satellite / balloon / UAV communication, a radio transceiver in a vehicle for a vehicle-to-vehicle (V2V) wireless network, etc.

[0019] In various embodiments of this teaching, the two ends of the communication (e.g., BS and UE) may be described herein as non-limiting examples of “wireless communication nodes” and “wireless communication devices” that can practice the methods disclosed herein and are capable of wireless and / or wired communication, according to various embodiments of this disclosure.

[0020] Figure 1 An exemplary communication network 100 according to an embodiment of the present disclosure is shown, in which the techniques disclosed herein can be implemented. Figure 1 As shown, the exemplary communication network 100 includes a base station (BS) 101 and multiple UEs (UE1 1110, UE2 120…UE3 130), wherein the BS 101 can communicate with the UEs according to a radio protocol. To ensure transmission reliability, the BS 101 needs to perform link adaptation based on channel quality feedback from the UEs. In applications of URLLC services, it is desirable for each UE to send this channel quality feedback (e.g., CSI feedback) in a timely and accurate manner.

[0021] Figure 2 A block diagram of a base station (BS) 200 according to some embodiments of the present disclosure is shown. The BS 200 is an example of a node or device that can be configured to implement the various methods described herein. Figure 2As shown, BS 200 includes a body 240, which includes a system clock 202 (also called clock 202), a processor 204, a memory 206, a transceiver 210 including a transmitter 212 and a receiver 214, a power module 208, a CSI report configurator 220, and a CSI report analyzer 222.

[0022] In this embodiment, system clock 202 provides timing signals to processor 204 to control the timing of all operations of BS 200. Processor 204 controls the overall operation of BS 200 and may include one or more processing circuits or modules, such as a central processing unit (CPU) and / or any combination of the following: general-purpose microprocessor, microcontroller, digital signal processor (DSP), field programmable gate array (FPGA), programmable logic device (PLD), controller, state machine, gated logic, discrete hardware components, dedicated hardware finite state machine, or any other suitable circuit, device, and / or structure capable of performing data computation or other operations.

[0023] Memory 206 can provide instructions and data to processor 204. Memory 206 may include both read-only memory (ROM) and random access memory (RAM). A portion of memory 206 may also include non-volatile random access memory (NVRAM). Processor 204 typically performs logical and arithmetic operations based on program instructions stored in memory 206. Instructions stored in memory 206 (also referred to as software) can be executed by processor 204 to perform the methods described herein. Processor 204 and memory 206 together form a processing system that stores and executes software. As used herein, “software” means any type of instructions that can configure a machine or device to perform one or more desired functions or processes, whether it is referred to as software, firmware, middleware, microcode, etc. Instructions may include code (e.g., in source code format, binary code format, executable code format, or any other suitable code format). When executed by one or more processors, instructions cause the processing system to perform the various functions described herein.

[0024] Transceiver 210 allows BS 200 to transmit and receive data from remote devices (e.g., UE or another BS), and includes transmitter 212 and receiver 214. Antenna 250 is typically attached to body 240 and electrically coupled to transceiver 210. In various embodiments, BS 200 includes (not shown) multiple transmitters, multiple receivers, and multiple transceivers. In one embodiment, antenna 250 is replaced by a multi-antenna array 250 that can form multiple beams, each pointing in a different direction. Transmitter 212 can be configured to wirelessly transmit packets with different packet types or functions, such packets being generated by processor 204. Similarly, receiver 214 is configured to receive packets with different packet types or functions, and processor 204 is configured to process packets of multiple different packet types. For example, processor 204 can be configured to determine the type of a packet and process the packet and / or its fields accordingly.

[0025] In wireless communication, the CSI report configurator 220 in the BS 200 can generate a configuration associated with the UE's Channel State Information (CSI) report. The CSI report configurator 220 can send the configuration to the UE via the transmitter 212. In some embodiments, the configuration can indicate the CSI report type.

[0026] In this example, the CSI report analyzer 222 can receive CSI reports from the UE via receiver 214. In some embodiments, the CSI report is generated based on a measurement performed according to the CSI report type, which is based on at least one of the following: Interference Measurement Resource (IMR), Channel Measurement Resource (CMR), or a transport block transmitted from BS 200 in the Physical Downlink Shared Channel (PDSCH).

[0027] In some embodiments, when the configuration does not include configuration information related to the IMR or CMR associated with the CSI report, the CSI report type indicates a first type. When the configuration does not include configuration information related to the IMR or CMR associated with the CSI report, the measurement is performed based on the transport blocks sent in the PDSCH associated with the CSI report.

[0028] In some embodiments, the BS 200 transmits multiple PDSCH repetitions associated with a CSI report to the UE via transmitter 212. The UE generates a CSI report based on one of the multiple PDSCH repetitions. A PDSCH repetition can be determined based on at least one of the following: the first PDSCH repetition in a system-predefined multiple PDSCH repetition, the last PDSCH repetition in a system-predefined multiple PDSCH repetition, sub-signaling in the configuration transmitted semi-statically via Radio Resource Control (RRC) signaling, or a trigger status indication dynamically indicated by downlink (DL) grant or uplink (UL) grant that triggers the CSI report.

[0029] In some embodiments, after receiving multiple PDSCH repeats associated with a CSI report, the UE generates a CSI report based on a combination of some or all of the multiple PDSCH repeats. The "some or all" PDSCH repeats can be determined based on at least one of the following: some PDSCH repeats based on system-predefined multiple PDSCH repeats; some PDSCH repeats indicated by sub-signaling in a configuration semi-statically transmitted via Radio Resource Control (RRC) signaling; some PDSCH repeats dynamically indicated in a trigger status indication by a DL or UL authorization triggering the CSI report; all PDSCH repeats based on system-predefined multiple PDSCH repeats; all PDSCH repeats indicated by sub-signaling in a configuration semi-statically transmitted via RRC signaling; or all PDSCH repeats dynamically indicated in a trigger status indication by a DL or UL authorization triggering the CSI report.

[0030] In some embodiments, when the configuration includes configuration information related to the IMR and / or CMR associated with the CSI report, the CSI report type indicates a second type. When the configuration includes configuration information related to the IMR and / or CMR associated with the CSI report, measurements are performed based on the IMR and / or CMR sent to the UE. In some embodiments, the UE may perform measurements based on at least one of the following: determining the start time related to the IMR and / or CMR associated with the CSI report; determining the end time related to the IMR and / or CMR; or measuring CSI based on the start time, the end time, and each IMR and / or CMR time between the start time and the end time.

[0031] In some embodiments, the start timing is determined based on at least one of the following: the time slot or sub-time slot in which the DL grant or UL grant triggers the CSI report to be sent to the UE; the time slot or sub-time slot in which the DL grant or UL grant is located when the end symbol of the DL grant or UL grant is not later than a predetermined time position; the next time slot or sub-time slot in which the DL grant or UL grant is located when the end symbol of the DL grant or UL grant is later than the predetermined time position, wherein the predetermined time position is determined based on the semi-static configuration of BS 200 or based on system predefined parameters; or the next available time slot or sub-time slot in which the DL grant or UL grant is located when the end symbol of the DL grant or UL grant is later than the predetermined time position, wherein the predetermined time position is determined based on the semi-static configuration of BS 200 or based on system predefined parameters. The next available time slot or sub-time slot may be used for downlink transmission and is not necessarily an uplink time slot or uplink sub-time slot.

[0032] In some embodiments, the termination timing is determined based on the last IMR and / or CMR timing of the reference resource for the CSI report triggered no later than the time-domain configuration of the IMR and / or CMR. The reference resource for the CSI report is determined as n time units prior to the first Orthogonal Frequency-Division Multiplexing (OFDM) symbol before the transmission of the CSI report. Each of the n time units is one of the following: OFDM symbol, sub-slot, or slot; where n is an integer determined based on the semi-static configuration of the BS 200, system predefined parameters, and / or UE capability determination.

[0033] In some embodiments, this configuration instructs the UE to include CSI statistics in the CSI report. Statistics can be calculated for the CSI report when a measurement is performed under at least one of the following conditions: According to the first condition, the measurement is performed for at least N IMR and / or CMR timings, where N is a positive integer determined based on a semi-static configuration of the BS 200 or a system predefined value. According to the second condition, the measurement is performed within a monitoring window having a length of at least M time units, where M is a positive integer determined based on a semi-static configuration of the BS 200 or a system predefined value. Each of the M time units is one of the following: OFDM symbol, sub-slot, or slot.

[0034] In some embodiments, this configuration instructs the UE to include CSI statistics in the CSI report. However, when a CSI measurement is performed without at least one of the following conditions, the UE may generate a CSI report without statistics or cancel the CSI report. According to the first condition, the measurement is performed at least N IMR and / or CMR times, where N is a positive integer determined based on a semi-static configuration of the BS 200 or a system predefined value. According to the second condition, the measurement is performed within a monitoring window having a length of at least M time units, where M is a positive integer determined based on a semi-static configuration of the BS 200 or a system predefined value. Each of the M time units is one of the following: OFDM symbol, sub-slot, or slot.

[0035] In some embodiments, this configuration indicates the end timeout related to IMR and / or CMR. CSI report analyzer 222 can receive CSI reports from the UE at a time location on the Physical Uplink Control Channel (PUCCH) resource. When the end timeout related to IMR and / or CMR is in a first time unit, the time location can be another first time unit, which is N second time units later than the first time unit. Each first time unit is one of the following: OFDM symbol, sub-slot, or time slot; and each second time unit is one of the following: OFDM symbol, sub-slot, or time slot, where N is an integer determined based on: the semi-static configuration of BS 200, system predefined parameters, and / or the capabilities of the UE. For example, although the end timeout related to IMR and / or CMR is at the second OFDM symbol of the first time slot, the time location can be the second OFDM symbol of the third time slot, which is two time slots later than the second OFDM symbol of the first time slot.

[0036] In some embodiments, this configuration indicates the end position of the monitoring window for IMR and / or CMR measurements. The CSI report analyzer 222 can receive CSI reports from the UE on the Physical Uplink Control Channel (PUCCH) resource at the time position. The time position can be determined as a first time unit N second time units later than the end position. The first time unit is one of the following: OFDM symbol, sub-slot, or time slot; and each second time unit is one of the following: OFDM symbol, sub-slot, or time slot, where N is an integer determined based on the following: the semi-static configuration of the BS 200, system predefined parameters, and / or the capabilities of the UE.

[0037] In some embodiments, this configuration instructs the UE to measure aperiodic CSI based on aperiodic IMR and / or CMR. When it is determined that the time-frequency resources occupied by the aperiodic IMR and / or CMR partially or completely overlap with the time-frequency resources of the PDSCH, the UE can perform rate matching for the overlapping time-frequency resources when the UE receives the PDSCH. In various embodiments, the PDSCH is scheduled by at least one of the following: DL authorization or UL authorization that triggers aperiodic CSI reporting; another downlink control information (DCI); or semi-persistent scheduling (SPS) PDSCH.

[0038] The power module 208 may include a power source (e.g., one or more batteries) and a power regulator to supply power to... Figure 2 Each of the modules described above provides regulated power. In some embodiments, if BS 200 is coupled to a dedicated external power source (e.g., a wall outlet), power module 208 may include a transformer and a power conditioner.

[0039] The various modules discussed above are coupled together via bus system 230. In addition to the data bus, bus system 230 may also include, for example, a power bus, a control signal bus, and / or a status signal bus. It should be understood that the modules of BS 200 can be operatively coupled to each other using any suitable technology and media.

[0040] Despite Figure 2 While multiple individual modules or components are shown, those skilled in the art will understand that one or more of these modules can be combined or implemented together. For example, processor 204 can implement not only the functions described above regarding processor 204, but also the functions described above regarding CSI report configurator 220. Conversely, Figure 2 Each module shown can be implemented using multiple individual parts or components.

[0041] Figure 3 The following are some embodiments of the present disclosure, illustrated by a BS (e.g., Figure 2 The flowchart below shows the method 300 for CSI measurement and reporting executed by the BS (BS 200). In operation 310, the BS generates a configuration associated with the Channel State Information (CSI) report of the UE. In operation 320, the BS sends this configuration to the UE. In operation 330, the BS receives and analyzes the CSI report from the UE. Figure 3 The order of operations shown may be varied depending on different embodiments of this disclosure.

[0042] Figure 4 A block diagram of a UE 400 according to some embodiments of the present disclosure is shown. The UE 400 is an example of a device that can be configured to implement the various methods described herein. Figure 4 As shown, UE 400 includes a main body 440, which includes a system clock 402 (also called clock 402), a processor 404, a memory 406, a transceiver 410 including a transmitter 412 and a receiver 414, a power module 408, a CSI report configuration analyzer 420, a channel state measurer 422, a CSI report generator 424, a statistics calculator 426, a CSI report time location determiner 428, and a rate matching actuator 429.

[0043] In this embodiment, the system clock 402, processor 404, memory 406, transceiver 410, and power module 408 operate similarly to the system clock 202, processor 204, memory 206, transceiver 210, and power module 208 in BS 200. Antenna 450 or multi-antenna array 450 is typically attached to the body 440 and electrically coupled to transceiver 410.

[0044] In this example, the CSI report configuration analyzer 420 can receive the configuration associated with the Channel State Information (CSI) report from the BS via receiver 414. The CSI report configuration analyzer 420 can analyze this configuration to determine the CSI report type based on it. Depending on the CSI report type, the channel state measurer 422 can perform measurements based on at least one of the following: Interference Measurement Resource (IMR), Channel Measurement Resource (CMR), or a transport block transmitted from the BS in the Physical Downlink Shared Channel (PDSCH). In this example, the CSI report generator 424 can generate a CSI report based on the measurements and transmit the CSI report to the BS via transmitter 412.

[0045] In some embodiments, when the configuration does not include configuration information related to the IMR or CMR associated with the CSI report, the CSI report type is determined to be a first type. When the configuration does not include configuration information related to the IMR or CMR associated with the CSI report, the measurement is performed based on the transport blocks sent in the PDSCH associated with the CSI report.

[0046] In some embodiments, UE 400 may receive multiple PDSCH repetitions associated with a CSI report from BS via receiver 414; and identify one PDSCH repetition among the multiple PDSCH repetitions. CSI report generator 424 may generate a CSI report based on the PDSCH repetition. A PDSCH repetition may be determined based on at least one of the following: the first PDSCH repetition among multiple PDSCH repetitions predefined by the system, the last PDSCH repetition among multiple PDSCH repetitions predefined by the system, sub-signaling in the configuration received semi-statically via Radio Resource Control (RRC) signaling, or a trigger status indication dynamically indicated by downlink (DL) grant or uplink (UL) grant that triggers the CSI report.

[0047] In some embodiments, after receiving multiple PDSCH repeats associated with a CSI report, the CSI report generator 424 generates a CSI report based on a combination of some or all of the multiple PDSCH repeats. The "some or all" PDSCH repeats can be determined based on at least one of the following: some PDSCH repeats based on system-predefined multiple PDSCH repeats; some PDSCH repeats indicated by sub-signaling in the configuration received semi-statically via Radio Resource Control (RRC) signaling; some PDSCH repeats dynamically indicated in the trigger status indication by the DL or UL authorization that triggers the CSI report; all PDSCH repeats based on system-predefined multiple PDSCH repeats; all PDSCH repeats indicated by sub-signaling in the configuration received semi-statically via RRC signaling; or all PDSCH repeats dynamically indicated in the trigger status indication by the DL or UL authorization that triggers the CSI report.

[0048] In some embodiments, when the configuration includes configuration information related to the IMR and / or CMR associated with the CSI report, the CSI report type is determined to be a second type. When the configuration includes configuration information related to the IMR and / or CMR associated with the CSI report, measurements are performed based on the IMR and / or CMR received from the BS.

[0049] In some embodiments, the channel state measuring device 422 may perform measurements based on at least one of the following: determining the start timing of the IMR and / or CMR associated with the CSI report; determining the end timing of the IMR and / or CMR; and / or measuring the CSI based on the start timing, the end timing, and each IMR and / or CMR timing between the start timing and the end timing.

[0050] In some embodiments, the start timing is determined based on at least one of the following: the time slot or sub-time slot in which the DL grant or UL grant triggers the CSI report, received from the BS; the time slot or sub-time slot in which the DL grant or UL grant is located when the end symbol of the DL grant or UL grant is not later than a predetermined time position; the next time slot or sub-time slot in which the DL grant or UL grant is located when the end symbol of the DL grant or UL grant is later than the predetermined time position, wherein the predetermined time position is determined by the BS based on a semi-static configuration or based on system predefined criteria; or the next available time slot or sub-time slot in which the DL grant or UL grant is located when the end symbol of the DL grant or UL grant is later than the predetermined time position, wherein the predetermined time position is determined based on the BS's semi-static configuration or based on system predefined criteria. The next available time slot or sub-time slot may be used for downlink transmission and is not necessarily an uplink time slot or uplink sub-time slot.

[0051] In some embodiments, the termination timing is determined based on the timing of the last IMR and / or CMR, according to the time-domain configuration of the IMR and / or CMR, wherein the timing of the last IMR and / or CMR is no later than the reference resource of the CSI report triggered by DL authorization or UL authorization. The reference resource of the CSI report is determined as n time units preceding the first Orthogonal Frequency Division Multiplexing (OFDM) symbol of the CSI report. Each of the n time units is one of the following: OFDM symbol, sub-slot, or slot; where n is an integer determined based on the following: the semi-static configuration of the BS, system predefined, and / or the capabilities of the UE 400.

[0052] In some embodiments, the CSI report configuration analyzer 420 can determine that the configuration indicates the inclusion of CSI statistics in the CSI report. Based on this determination, the statistics calculator 426 can calculate the statistics of the CSI report when the channel state measurement device 422 performs a measurement under at least one of the following conditions: According to the first condition, the measurement is performed for at least N IMR and / or CMR timings, where N is a semi-static configuration based on the BS or a positive integer determined by a system predefined condition. According to the second condition, the measurement is performed within a monitoring window having a length of at least M time units, where M is a semi-static configuration based on the BS or a positive integer determined by a system predefined condition. Each of the M time units is one of the following: OFDM symbol, sub-slot, or slot.

[0053] In some embodiments, after the CSI report configuration analyzer 420 determines that the configuration indicates the inclusion of CSI statistics in the CSI report, when the channel state measurement unit 422 performs a measurement if at least one of the following conditions is not met, the UE 400 may generate a CSI report without statistics or determine to cancel the CSI report. According to the first condition, the measurement is performed at least N IMR and / or CMR times, where N is a semi-static configuration based on the BS or a positive integer determined by a system predefined value. According to the second condition, the measurement is performed within a monitoring window having a length of at least M time units, where M is a semi-static configuration based on the BS or a positive integer determined by a system predefined value. Each of the M time units is one of the following: OFDM symbol, sub-slot, or slot.

[0054] In this example, the CSI report time location determiner 428 can determine the time location for sending the CSI report. In some embodiments, the CSI report time location determiner 428 can determine a first time unit in which the end time associated with the IMR and / or CMR is located, and determine that the time location for sending the CSI report is another first time unit, which is N second time units later than the first time unit. Each first time unit is one of the following: OFDM symbol, sub-slot, or time slot; and each second time unit is one of the following: OFDM symbol, sub-slot, or time slot, where N is an integer determined based on the following: the semi-static configuration of the BS, system predefined, and / or the capabilities of the UE 400. For example, although the end time associated with the IMR and / or CMR is located at the second OFDM symbol of the first time slot, the time location could be the second OFDM symbol of the third time slot, which is two time slots later than the second OFDM symbol of the first time slot. Then, at that time location, a CSI report is sent to the BS on the Physical Uplink Control Channel (PUCCH) resource.

[0055] In some embodiments, the CSI report time location determiner 428 can determine the end position of the monitoring window for IMR and / or CMR measurements; and determine the time location for sending the CSI report as a first time unit, which is N second time units later than the end position. The first time unit is one of the following: OFDM symbol, sub-slot, or time slot; and each second time unit is one of the following: OFDM symbol, sub-slot, or time slot, where N is an integer determined based on the following: the semi-static configuration of the BS, system predefined parameters, and / or the capabilities of the UE 400. The CSI report is then sent to the BS on PUCCH resources at this time location.

[0056] In this example, rate matching actuator 429 can perform rate matching. In some embodiments, after CSI report configuration analyzer 420 determines that the configuration indication is based on aperiodic IMR and / or CMR measurements of aperiodic CSI, rate matching actuator 429 can determine that the time-frequency resources occupied by the aperiodic IMR and / or CMR partially or completely overlap with the time-frequency resources of the PDSCH. In this case, when the PDSCH is received via receiver 414, rate matching actuator 429 can perform rate matching for the overlapping time-frequency resources. In various embodiments, the PDSCH is scheduled by at least one of the following: triggering a DL authorization or UL authorization for aperiodic CSI reports; another downlink control information (DCI); or semi-static semi-persistent scheduling (SPS) PDSCH.

[0057] The various modules discussed above are coupled together via bus system 430. In addition to the data bus, bus system 430 may also include, for example, a power bus, a control signal bus, and / or a status signal bus. It should be understood that the modules of UE 400 can be operatively coupled to each other using any suitable technology and media.

[0058] Despite Figure 4 While multiple individual modules or components are shown, those skilled in the art will understand that one or more of these modules can be combined or implemented together. For example, processor 404 can implement not only the functions described above for processor 404, but also the functions described above for CSI report configuration analyzer 420. Conversely, Figure 4 Each module shown can be implemented using multiple individual parts or components.

[0059] Figure 5 The following are some embodiments of the UE (e.g., according to the present disclosure) Figure 4 The flowchart below shows a method 500 for CSI measurement and reporting executed by UE 400. In operation 510, the UE receives a configuration associated with a Channel State Information (CSI) report from the BS. In operation 520, the UE determines the CSI report type based on this configuration. In operation 530, depending on the CSI report type, the UE performs a measurement based on at least one of IMR, CMR, or PDSCH from the BS. In operation 540, the UE generates a CSI report based on the measurement and configuration. In operation 550, the UE sends the CSI report to the BS. Figure 5 The order of operations shown may be varied depending on different embodiments of this disclosure.

[0060] Different embodiments of this disclosure will now be described in detail below. Note that the features of the embodiments and examples in this disclosure can be combined with each other in any way without conflict.

[0061] The first embodiment describes a method for determining which time of PDSCH repetition the CSI report should be based on. The CSI reports fed back by the UE to the BS support one or more types. For one type of CSI report, the UE measures CSI based on the PDSCH. For other types of CSI reports, the UE measures CSI based on the CSI Reference Signal (CSI-RS) or CSI Interference Measurement (CSI-IM). CSI reports can be aperiodic, semi-persistent, or periodic CSI feedback.

[0062] For PDSCH that supports repeated transmissions, the BS can indicate to the UE the number of times the PDSCH is repeatedly transmitted, for example, twice, four times, or eight times, via semi-static RRC signaling or dynamic DCI signaling. When instructing the UE to measure and report CSI based on one or more of the multiple PDSCH repeated transmissions, at least one of the following methods can be used to indicate to the UE at which time of the PDSCH repeated transmission to calculate the CSI report.

[0063] First, the system can predefine that in multiple PDSCH retransmissions, the UE always calculates the CSI based on the nth PDSCH retransmission. The nth retransmission can be the first or the last PDSCH retransmission in multiple PDSCH retransmissions.

[0064] Second, the BS can semi-statically configure the calculation of CSI reports based on the m-th PDSCH repetition via RRC signaling. For example, m is one of the M repetitions of PDSCH, and the PDSCH needs to be sent M times via semi-static or dynamic configuration. The BS can add sub-signaling to the CSI report configuration carried by RRC signaling to indicate m, where the CSI report configuration corresponds to the CSI report type or CSI feedback type based on PDSCH measurements.

[0065] Third, the BS can dynamically instruct the calculation of a CSI report based on the xth PDSCH repetition via DCI. The BS can send a DL grant or UL grant to trigger a CSI report of a specified feedback type. The “DL grant” or “UL grant” indicates the CSI report triggering state, which includes an indication of the xth PDSCH repetition, allowing the UE to calculate a “CSI report” based on the received xth PDSCH repetition.

[0066] Fourth, the system can predefine that for repeatedly transmitted PDSCH, the UE calculates the CSI report based on the combination of some or all of the PDSCH repetitions in multiple PDSCH repetitions.

[0067] Fifth, the BS can semi-statically configure via RRC signaling whether the UE calculates the CSI report based on a combination of some or all of the PDSCH repetitions in multiple PDSCH repetitions. The BS can add sub-signaling to the CSI report configuration carried by RRC signaling to indicate this. If the sub-signaling indicates yes, the UE needs to calculate and report the CSI report based on a combination of some or all of the PDSCH repetitions in multiple PDSCH repetitions. If the sub-signaling indicates no, the UE calculates and reports the CSI report based on one repetition of the received PDSCH.

[0068] Sixth, the BS can dynamically instruct the UE whether to calculate a CSI report based on the combined result of some or all of the PDSCH repetitions in multiple PDSCH repetitions. For example, the BS sends a DL grant or UL grant to trigger a CSI report of a specified type. The DL grant or UL grant indicates the CSI report trigger status, which includes this indication. If the CSI report trigger status indication is yes, the UE needs to calculate and report a CSI report based on the combined result of some or all of the PDSCH repetitions in multiple PDSCH transmissions. If the CSI report trigger status indication is no, the UE calculates and reports a CSI report based on one repetition of the received PDSCH.

[0069] The second embodiment describes a method for determining the start and end CSI-RS timings triggered by DL grant or UL grant. After the BS sends a DL grant or UL grant to trigger a CSI report, the UE sends a CSI report back to the BS. The CSI report may contain some statistical information about the channel state. The UE measures interference information for calculating the CSI report based on IMR measurements; and / or measures channel information for calculating the CSI report based on CMR measurements. Simultaneously with sending the DL grant or UL grant to trigger CSI feedback, the BS also triggers the corresponding IMR and / or CMR. The UE needs to measure CSI based on multiple IMR and / or CMR timings to generate the CSI report.

[0070] The first IMR timing or the first CMR timing can be determined using at least one of the following methods. In one method, the time slot or sub-slot in which the UE receives the DL grant or UL grant that triggers the CSI report is the first timing for the UE to receive the IMR and / or CMR to measure the CSI. In another method, if the end symbol of the DL grant or UL grant received by the UE to trigger the CSI report is no later than time position A, the UE will receive the IMR and / or CMR on the time slot or sub-slot where the DL grant or UL grant is located. Otherwise, the UE will receive the IMR and / or CMR on the next available time slot or sub-slot where the DL grant or UL grant is located. The next available time slot or sub-slot can be a next time slot or sub-slot. The next available time slot or sub-slot can be used for downlink transmission and may not necessarily be an uplink time slot or uplink sub-slot. Time position A can be predefined by the system or semi-statically configured by the BS, and it can be an OFDM symbol index within a time slot or sub-slot.

[0071] The end or final timing of several IMR or CMR timings can be determined as follows: The UE determines the end timing of the received IMR and / or CMR based on the reference resource of the CSI report triggered by DL authorization or UL authorization. The reference resource of the CSI report can be determined as n time units prior to the transmission of the first OFDM symbol of the CSI report fed back by the UE. This time unit can be an OFDM symbol, a sub-slot, or a slot. n is an integer predefined by the system or an integer determined based on the semi-static configuration of the BS and / or UE capabilities. According to the time-domain configuration of the IMR and / or CMR, the last IMR and / or CMR timing no later than the reference resource of the CSI report is the end timing of the IMR and / or CMR received by the UE for measurement.

[0072] After the UE determines the first IMR and / or CMR timing to be measured and the last IMR and / or CMR timing to be measured, the UE needs to receive and measure all IMR and / or CMR timings from the first timing to the last timing. CMR can be a periodic CSI-RS resource or a semi-persistent CSI-RS resource. IMR can be a periodic CSI-RS resource, a semi-persistent CSI-RS resource, a periodic CSI-IM resource, or a semi-persistent CSI-IM resource.

[0073] The third embodiment describes the relationship between CSI reporting quantities and IMR and / or CMR. The BS configures the CSI report via RRC signaling to determine what information should be included in the CSI report. The specific feedback quantities included in the CSI report can be configured via RRC signaling reporting quantities or another RRC signaling. For Type 1 CSI reports, the feedback information included in the CSI report does not include quantities of statistical information reflecting channel state information, such as average values, variance values, etc. For Type 2 CSI reports, the feedback information included in the CSI report includes statistical information of channel state information, such as average values, variance values, etc. For Type 2 CSI reports, the UE needs to measure IMR and / or CMR for a period of time to obtain the statistical information for the CSI report. For Type 1 CSI reports, there is no such restriction on the UE's measurements.

[0074] If the BS configures a CSI report including a Type 2 CSI report via RRC signaling, the UE measurement should meet at least one of the following conditions. First, the UE needs to measure at least n IMR and / or CMR opportunities to calculate and feed back the CSI report. n is predefined by the system or semi-statically configured by the BS. The n IMR and / or CMR opportunities can be n opportunities arranged sequentially or out of order. Second, the UE can only calculate and feed back the CSI report after measuring the length of a monitoring window with at least m time units. m is predefined by the system or semi-statically configured by the BS. The time unit is an OFDM symbol, sub-slot, or slot. These m time units can be continuous or discontinuous in the time domain.

[0075] If the UE's measurement does not meet at least one of the above conditions, the UE will use one of the following methods to report the CSI: the UE will abandon the CSI report; or the UE will downgrade the Type 2 CSI report to a Type 1 CSI report and report the Type 1 CSI report.

[0076] The fourth embodiment describes how to determine the PUCCH resources used to carry the CSI report. After the BS sends a DL grant or UL grant to trigger the CSI report, the UE sends the CSI report back to the BS. For example, the BS indicates a trigger state in the DL grant or UL grant to indicate how the UE should send the CSI report. In the trigger state indicated in the DL grant or UL grant, the BS may indicate the number of IMR and / or CMR measurement opportunities corresponding to the CSI report, or indicate the monitoring window length for the IMR and / or CMR measurements corresponding to the CSI report.

[0077] Based on the number of IMR and / or CMR measurement opportunities indicated by the BS, or the length of the monitoring window for IMR and / or CMR measurements, the UE can determine the timing of the PUCCH resource used to transmit the CSI report based on at least one of the following methods.

[0078] In the first method, the BS indicates to the UE the number of IMR and / or CMR opportunities corresponding to the CSI report as K. After the BS triggers the CSI report, the UE measures K consecutive IMR and / or CMR opportunities. The UE determines the end of the last opportunity among the K IMR and / or CMR opportunities as a first time unit. The UE determines a second time unit, which is N time units later than the first time unit, where N is predefined by the system, semi-statically configured by the BS, or determined based on UE capabilities. The UE transmits PUCCH resources carrying the CSI report in the determined second time unit. Each first time unit is an OFDM symbol, sub-slot, or time slot. Each second time unit is an OFDM symbol, sub-slot, or time slot.

[0079] In the second method, the BS indicates to the UE that the monitoring window length for the IMR and / or CMR measurements corresponding to the CSI report is b third time units. After the BS triggers the CSI report, the UE measures the CSI over b uninterrupted or consecutive third time units. The UE determines a first time unit, which is N second time units later than the end of the b third time units of the monitoring window. The UE transmits PUCCH resources carrying the CSI report within the determined first time unit. Each first time unit is an OFDM symbol, sub-slot, or time slot. Each second time unit is an OFDM symbol, sub-slot, or time slot. Each third time unit is an OFDM symbol, sub-slot, or time slot. N is predefined by the system, semi-statically configured by the BS, or determined based on UE capabilities. The UE transmits PUCCH resources carrying the CSI report within the determined first time unit to feed back the CSI report to the BS.

[0080] The fifth embodiment describes when to perform PDSCH rate matching with respect to the IMR / CMR. The BS can trigger the UE to feedback aperiodic CSI via DL grant or UL grant. Aperiodic CSI is measured based on the aperiodic IMR and / or CMR. If the time-frequency resources occupied by the aperiodic IMR and / or CMR partially or completely overlap with the time-frequency resources of the PDSCH sent by the BS to the UE, rate matching can be performed on the overlapping resources when the UE receives the PDSCH. The PDSCH can be scheduled via DL grant that triggers the aperiodic CSI, via other DCIs, or via semi-static SPS PDSCH.

[0081] The sixth embodiment describes how to determine which type of CSI report is triggered for the UE. The CSI report sent by the UE to the BS can be of type one or type two. Type one and type two CSI reports can have different feedback content and / or be used to measure CSI for different downlink channels or signals. Type one CSI reports contain CSI acquired based on PDSCH reception. Type two CSI reports contain CSI acquired based on IMR and / or CMR reception. CMR can be a CSI-RS resource, and IMR can be a CSI-RS resource or a CSI-IM resource.

[0082] The BS configures at least one CSI reporting configuration for the UE via RRC signaling. Each CSI reporting configuration corresponds to either a first-type CSI report or a second-type CSI report. The UE determines whether a CSI report is of the first or second type based on the following method: The UE first determines whether the CSI reporting configuration associated with the triggered CSI report contains IMR and / or CMR configurations. If the CSI reporting configuration contains IMR and / or CMR configurations, the UE determines the CSI report to be of the first type. Otherwise, the UE determines the CSI report to be of the second type.

[0083] After the UE determines the type of CSI report, the UE measures the CSI accordingly. If the UE determines that the CSI report is of type 1, the UE measures the signal based on the PDSCH reception and feeds back the corresponding CSI report to the BS. If the UE determines that the CSI report is of type 2, the UE measures the signal based on the IMR and / or CMR associated with the CSI report and feeds back the corresponding CSI report to the BS.
