Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and more specifically, to methods and apparatus for receiving and transmitting information. Background Technology

[0002] 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 near-5G communication systems. Therefore, 5G or near-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 60GHz band, to achieve higher data rates. To reduce radio wave propagation loss and increase transmission distance, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive MIMO technologies are discussed in 5G communication systems.

[0004] In addition, in 5G communication systems, development is underway to improve system networks based on advanced small cells, cloud radio access networks (RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, cooperative multipoint (CoMP), and receiver interference cancellation.

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

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

[0007] To enhance the scheduling efficiency of wireless communication systems, base stations need to acquire channel state information (CSI) to perform scheduling accordingly based on the CSI feedback from terminal devices. However, how to further improve the performance of CSI reporting remains an unresolved issue.

[0008] One aspect of this disclosure provides a method executed by a user equipment (UE) in a wireless communication system, the method comprising: receiving L channel state information (CSI) reporting configurations, where L is an integer greater than 1; transmitting a first uplink channel triggered based on a first CSI reporting configuration among the L CSI reporting configurations; transmitting a second uplink channel associated with the first uplink channel, wherein the second uplink channel carries CSI reports associated with the first CSI reporting configuration, wherein the priority of the CSI reporting association is determined based on one of the following: the value of the priority associated with the L CSI reporting configurations; or the second CSI reporting configuration among the L CSI reporting configurations.

[0009] In one example, the value of the first priority carried by the second uplink channel that is not associated with the first CSI reporting configuration is less than the maximum value among the priority values ​​associated with the L CSI reporting configurations respectively, and the value of the first priority is greater than the minimum value among the priority values ​​associated with the L CSI reporting configurations respectively.

[0010] In one example, the value of the second priority associated with the CSI report carried by the third uplink channel that overlaps with the second uplink channel is less than the maximum value among the priority values ​​associated with the L CSI report configurations respectively, and the value of the second priority is greater than the minimum value among the priority values ​​associated with the L CSI report configurations respectively.

[0011] In one example, the priority value associated with the CSI report is one of the following: the minimum value among the L priority values ​​associated with the L CSI report configurations; the maximum value among the L priority values ​​associated with the L CSI report configurations; the sum of the L priority values ​​associated with the L CSI report configurations; or the average of the L priority values ​​associated with the L CSI report configurations.

[0012] In one example, the second CSI reporting configuration includes at least one of the following: the first CSI reporting configuration among the L CSI reporting configurations; the CSI reporting configuration with the lowest identifier ID value among the L CSI reporting configurations; the CSI reporting configuration with the lowest associated priority value among the L CSI reporting configurations; and the CSI reporting configuration indicated by the base station among the L CSI reporting configurations.

[0013] In one example, the second CSI reporting configuration is indicated by a parameter included in at least one of the L CSI reporting configurations, wherein the value v of the parameter corresponds to the (v+1)th CSI reporting configuration among the L CSI reporting configurations, and v is an integer greater than or equal to 0.

[0014] In one example, the priority associated with the second CSI reporting configuration is used to determine at least one of the following: multiplexing of CSI reports; discarding of CSI reports; sending of CSI reports; and the order of information bits in CSI reports.

[0023] In one example, the L CSI reporting configurations include the same parameters for indicating the resources of the first uplink channel; the L CSI reporting configurations indicate the same ID of the resources of the first uplink channel; the L CSI reporting configurations indicate the same period and / or offset of the resources associated with the first uplink channel; and the L CSI reporting configurations indicate the same bandwidth portion (BWP) of the resources associated with the first uplink channel.

[0063] The various embodiments of this disclosure can be applied to various communication systems, such as: Global System for Mobile Communications (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS), Long Term Evolution (LTE) systems, Frequency Division Duplex (FDD) systems, Time Division Duplex (TDD) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, 5th Generation (5G) systems, or New Radio (NR), etc. Furthermore, the various embodiments of this disclosure can be applied to future-oriented communication technologies.

[0064] Figure 1 An example wireless network 100 according to various embodiments of the present disclosure is shown. Figure 1 The embodiment of the wireless network 100 shown is for illustrative purposes only. Other embodiments of the wireless network 100 can be used without departing from the scope of this disclosure.

[0065] Wireless 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 proprietary IP network, or other data network).

[0066] Depending on the network type, other well-known terms such as "base station" or "access point" can be used instead of "gNodeB" or "gNB". For convenience, the terms "gNodeB" and "gNB" are used in this patent document to refer to network infrastructure components that provide wireless access for remote terminals. Furthermore, depending on the network type, other well-known terms such as "mobile station", "user 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 patent document to refer to remote wireless devices that wirelessly access the gNB, whether the UE is a mobile device (such as a mobile phone or smartphone) or a fixed device as commonly understood (such as a desktop computer or vending machine).

[0067] gNB 102 provides wireless broadband access to network 130 to multiple first user equipments (UEs) within its coverage area 120. The multiple first UEs include: UE 111, which may be located in a small business (SB); UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi hotspot (HS); UE 114, which may be located in a first residence (R); UE 115, which may be located in a second residence (R); and UE 116, which may be a mobile device (M), such as a cellular phone, wireless laptop computer, wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 to multiple second UEs within its coverage area 125. The multiple second UEs include UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 are capable of communicating with each other and with UEs 111-116 using 5G, LTE, LTE-A, WiMAX, or other advanced wireless communication technologies.

[0068] The dashed lines indicate the approximate extent of coverage areas 120 and 125, which are shown as approximately circular for illustrative and explanatory purposes only. It should be clearly understood that coverage areas associated with the gNB, 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.

[0069] 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 this disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook design and architecture for systems having 2D antenna arrays.

[0070] although Figure 1 An example of a wireless network 100 is shown, but it is possible to... Figure 1 Various modifications can be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Furthermore, 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, gNBs 101, 102, and / or 103 can provide access to other or additional external networks (such as external telephone networks or other types of data networks).

[0071] Figure 2A and Figure 2B Example wireless transmit and receive paths according to this disclosure are shown. In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102), while receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that receive path 250 can be implemented in a gNB, and transmit path 200 can be implemented in a UE. In some embodiments, receive path 250 is configured to support codebook design and structure for a system having a 2D antenna array as described in embodiments of this disclosure.

[0072] 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, a cyclic prefix addition block 225, and an up-converter (UC) 230. The receive path 250 includes a down-converter (DC) 255, a cyclic prefix removal 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.

[0073] In transmit path 200, 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 modulated symbols. Serial-to-parallel (S-to-P) block 210 converts (e.g., demultiplexes) the serial modulated symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in gNB 102 and UE 116. N-point IFFT block 215 performs IFFT operations on the N parallel symbol streams to generate a time-domain output signal. Parallel-to-serial block 220 converts (e.g., multiplexes) the parallel time-domain output symbols from N-point IFFT block 215 to generate a serial time-domain signal. Cyclic prefix addition block 225 inserts a cyclic prefix into the time-domain signal. Upconverter 230 modulates (e.g., upconverts) the output of the added cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at the baseband before being converted to the RF frequency.

[0074] The RF signal transmitted from gNB 102 reaches UE 116 after passing through the wireless channel, and UE 116 performs the opposite operation to that at gNB 102. Downconverter 255 downconverts the received signal to the baseband frequency, and cyclic prefix removal 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 a parallel time-domain signal. 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.

[0075] Each of gNBs 101-103 can implement a transmission path 200 similar to that used for transmission to UEs 111-116 in the downlink, and a reception path 250 similar to that used for reception from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 can implement a transmission path 200 for transmission to gNBs 101-103 in the uplink, and a reception path 250 for reception from gNBs 101-103 in the downlink.

[0076] Figure 2A and Figure 2B Each of the components can be implemented using only hardware, or using a combination of hardware and software / firmware. As a specific example, Figure 2A and Figure 2BAt least some of the components can be implemented in software, while others can be implemented in configurable hardware or a combination of software and configurable hardware. For example, FFT block 270 and IFFT block 215 can be implemented as configurable software algorithms, wherein the value of the number of points N can be modified according to the implementation method.

[0077] Furthermore, although the description uses FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of this disclosure. Other types of transforms, such as the Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions, can be used. 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 that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0078] although Figure 2A and Figure 2B An example of a wireless transmit and receive path is shown, but it is possible to modify it further. Figure 2A and Figure 2B Make various changes. For example, Figure 2A and Figure 2B The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. Furthermore, Figure 2A and Figure 2B This is intended to illustrate examples of the types of send and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.

[0079] Figure 3A Example UE 116 according to this disclosure is shown. Figure 3A The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1 UEs 111-115 can have the same or similar configurations. However, UEs have a wide variety of configurations, and Figure 3A This disclosure is not intended to limit the scope of any particular implementation of the UE.

[0080] UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a transmit (TX) processing circuitry 303, a microphone 304, and a receive (RX) processing circuitry 305. UE 116 also includes a speaker 306, a controller / processor 307, an input / output (I / O) interface 308, multiple input devices 309, a display 310, and a memory 311. The memory 311 includes an operating system (OS) 312 and one or more applications 313.

[0081] RF transceiver 302 receives incoming RF signals transmitted by a gNB of wireless network 100 from antenna 301. RF transceiver 302 down-converts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 305 sends the processed baseband signal to speaker 306 (e.g., for voice data) or to controller / processor 307 (e.g., for web browsing data) for further processing.

[0082] TX processing circuitry 303 receives analog or digital voice data from microphone 304, or other outgoing baseband data (such as network data, email, or interactive video game data) from controller / processor 307. TX processing circuitry 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. RF transceiver 302 receives the processed baseband or IF signals from TX processing circuitry 303 and up-converts the baseband or IF signals into RF signals transmitted via antenna 301.

[0083] The controller / processor 307 may include one or more processors or other processing devices and execute an OS 312 stored in memory 311 to control the overall operation of the UE 116. For example, the controller / processor 307 may control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceiver 302, the RX processing circuit 305, and the TX processing circuit 303 according to known principles. In some embodiments, the controller / processor 307 includes at least one microprocessor or microcontroller.

[0084] The controller / processor 307 is also capable of executing other processes and programs residing in the memory 311, such as operations for channel quality measurement and reporting for a system having a 2D antenna array as described in the embodiments of this disclosure. The controller / processor 307 is capable of moving data into or out of the memory 311 as needed for the execution of the process. In some embodiments, the controller / processor 307 is configured to execute an application 313 based on the OS 312 or in response to signals received from a gNB or operator. The controller / processor 307 is also coupled to an I / O interface IF 308, which provides the UE 116 with the ability to connect to other devices such as laptop computers and handheld computers. The I / O interface 308 is the communication path between these accessories and the controller / processor 307.

[0085] The controller / processor 307 is also coupled to input devices(s) 309 and a display 310. An operator of the UE 116 can use the input devices(s) 309 to input data into the UE 116. The display 310 may be a liquid crystal display or another display capable of displaying text and / or at least limited graphics (such as from a website). Memory 311 is coupled to the controller / processor 307. A portion of memory 311 may include random access memory (RAM), while another portion of memory 311 may include flash memory or other read-only memory (ROM).

[0086] 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 can be combined, further subdivided, or omitted, and additional components can be added as needed. As a specific example, the controller / processor 307 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although... Figure 3A The UE116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0087] Figure 3B An example gNB 102 according to this disclosure is shown. Figure 3B The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a wide variety of configurations, and Figure 3B The scope of this 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 structures as gNB 102.

[0088] like Figure 3B As shown, 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.

[0089] RF transceivers 372a-372n receive incoming RF signals, such as signals transmitted by the UE or other gNBs, from antennas 370a-370n. RF transceivers 372a-372n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 376, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 376 sends the processed baseband signals to controller / processor 378 for further processing.

[0090] 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. RF transceivers 372a-372n receive the outgoing processed baseband or IF signal from the TX processing circuit 374 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.

[0091] The controller / processor 378 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 may control the reception of forward channel signals and the transmission of reverse channel signals via RF transceivers 372a-372n, RX processing circuitry 376, and TX processing circuitry 374, according to known principles. The controller / processor 378 may also support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 378 may perform a BIS process, such as by a blind interference sensing (BIS) algorithm, and decode the received signal after subtracting interference. The controller / processor 378 may support any of a wide variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0092] The controller / processor 378 is also capable of executing programs and other processes, such as a basic operating system, residing in the memory 380. The controller / processor 378 is also capable of supporting channel quality measurement and reporting for systems having 2D antenna arrays as described in embodiments of this disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTCs. The controller / processor 378 is capable of moving data into or out of the memory 380 as needed for the execution of processes.

[0093] 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 over a network. The backhaul or network interface 382 is capable of supporting communication via any suitable wired or wireless connection(s). 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 technologies or NR, LTE, or LTE-A), the backhaul or network interface 382 allows 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 allows 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 architecture supporting communication via a wired or wireless connection, such as an Ethernet or RF transceiver.

[0094] Memory 380 is coupled to controller / processor 378. A portion of memory 380 may include RAM, while another portion may include flash memory or other ROM. In some embodiments, multiple instructions, such as a BIS algorithm, are stored in memory. The multiple instructions are configured to cause 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.

[0095] As described in more detail below, the transmit and receive paths of the gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuitry 374, and / or RX processing circuitry 376) support aggregated communication with FDD and TDD cells.

[0096] although Figure 3B An example of gNB 102 is shown, but it is possible to compare it with other models. Figure 3B Various modifications can be made. For example, gNB102 can include any number of... Figure 3A Each component shown. As a specific example, an access point can include multiple backhaul or network interfaces 382, ​​and a controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as a single instance including TX processing circuitry 374 and a single instance including RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0197] Optionally, the reference signal used for tracking can be a reference signal having tracking reference signal information parameters (e.g., trs-Info).

Optionally, when the reference signal associated with the indicated TCI state and / or the reference signal in the resource set is an SSB, the PCI of the SSB associated with the indicated TCI state is the same as the PCI of the SSB in the resource set.

Optionally, the first serving cell is indicated by the base station, or the first serving cell is predefined. For example, the first serving cell is indicated by a parameter (e.g., carrier) in the CSI reporting configuration. For example, when the CSI reporting configuration includes this parameter (e.g., carrier), the first serving cell is indicated by this parameter. For example, when the CSI reporting configuration does not include this parameter (e.g., carrier), the first serving cell is the serving cell where the CSI reporting configuration resides. For example, the first serving cell is the serving cell where a resource in the resource set resides. The method for determining the serving cell where a resource in the resource set resides is described above. Optionally, the first BWP can be indicated by the base station, or the first BWP can be a predefined BWP. For example, the first BWP is indicated by a parameter in the CSI reporting configuration.

Optionally, the first BWP can be a BWP associated with a resource set. Optionally, the first BWP and the BWP associated with a resource set can be indicated by the same parameter. For example, the ID of the first serving cell and the ID of the first BWP can be indicated by the parameter ServingCellAndBWP-Id. This parameter can be used to indicate the serving cell ID and the BWP ID. Here, the BWP can be a downlink BWP. Predefined BWPs can be: active BWP, initial BWP, default BWP, BWP with the smallest ID, or BWP with the largest ID.

[0231] In this document, the indicated TCI state associated with the first serving cell refers to the indicated TCI state applied / used on the first serving cell. In this document, the indicated TCI state associated with the first BWP refers to the indicated TCI state applied / used on the first BWP.

[0232] Optionally, the indicated TCI state refers to the most recent indicated TCI state prior to the first uplink channel. Optionally, the indicated TCI state refers to the most recent indicated TCI state prior to the reference resource associated with the first uplink channel. Optionally, the indicated TCI state refers to the most recent indicated TCI state prior to the second uplink channel. Optionally, the indicated TCI state refers to the most recent indicated TCI state prior to the CSI reference resource corresponding to the CSI report carried by the second uplink channel. Since the indicated TCI state can be time-varying, this method can clearly identify which indicated TCI state can be used for CSI initiation or event determination, preventing the UE from using incorrect indicated TCI states to trigger CSI or determine events, thus improving UE reliability.

[0233] In some cases, a UE can acquire multiple indicated TCI states. For example, the UE can acquire multiple indicated TCI states through DCI detection or MAC-CE reception. Here, the number of indicated TCI states can be one of 2, 3, or 4. For example, multiple indicated TCI states can be two TCI states. Optionally, the multiple TCI states apply to different TRPs. Optionally, each indicated TCI state can be applied to downlink channel / downlink signal reception and / or uplink channel / uplink signal transmission. Optionally, the multiple TCI states can be used / applied to one or more serving cells. Optionally, the multiple TCI states can be used / applied to one or more BWPs in a serving cell. Optionally, the multiple indicated TCI states apply to the same serving cell. Optionally, the multiple indicated TCI states apply to the same BWP. Optionally, the multiple indicated TCI states apply to the same BWP in the same serving cell.

[0234] The method for determining the serving cell associated with multiple indicated TCI states is described above. The method for determining the BWP among the serving cells associated with multiple indicated TCI states is also described above.

[0235] Optionally, the CSI reporting configuration associates a specific indicated TCI state among multiple TCI states. Optionally, the specific indicated TCI state among multiple TCI states can be used to determine the event associated with the CSI reporting configuration. Optionally, the specific indicated TCI state among multiple TCI states can be used to trigger a first uplink channel. Optionally, the specific indicated TCI state among multiple TCI states can be used to determine the CSI carried in a second uplink channel. Optionally, the specific indicated TCI state can be predefined or indicated by the base station. Optionally, the specific indicated TCI state can be predefined or indicated by the base station. For example, the specific indicated TCI state can be the first TCI state (or the last TCI state) among multiple TCI states. For example, the specific indicated TCI state is the first Y TCI states (or the last Y TCI states) among multiple TCI states. Here, Y ≥ 1. Optionally, Y is predefined or indicated by the base station. The value of Y can be one of 1, 2, 3, or 4. For example, a specific indicated TCI state can be indicated by a parameter in the CSI reporting configuration. This parameter is used to indicate that specific indicated TCI state. For example, in the case of two indicated TCI states among multiple indicated TCI states, this parameter corresponds to 1 bit. The first value of this parameter (e.g., 0) corresponds to the first indicated TCI state of the two indicated TCI states. The second value of this parameter (e.g., 1) corresponds to the second indicated TCI state of the two indicated TCI states.

[0236] This method can clearly identify which TRPs correspond to TCI states that can be used to initiate CSI or determine events, thus preventing the UE from using incorrect indicated TCI states to trigger CSI or determine events and improving UE reliability.

[0237] The reference signal resources associated with the activated TCI state are discussed below. The method for determining the activated TCI state is described above.

[0238] Optionally, the reference signal associated with the activated TCI state can be: the reference signal corresponding to the activated TCI state. Optionally, the reference signal associated with the activated TCI state can be at least one of the following: mode #3) a quasi-co-addressable SSB with the QCL reference signal of the activated TCI state; mode #4) the QCL reference signal of the activated TCI state. Optionally, a TCI state can be associated with / include / correspond to one or two QCL reference signals. Optionally, if a TCI state is associated with / includes / corresponds to two QCL reference signals, then the reference signal associated with the TCI state is the reference signal of QCL type D among the two QCL reference signals.

[0239] Optionally, the reference signal resource associated with the activated TCI state can be determined based on method #3 or method #4. Optionally, method #3 or method #4 can be indicated by the base station. For example, parameters included in the CSI reporting configuration indicate method #3 or method #4. Optionally, the reference signal resource associated with the activated TCI state can be determined based on the reference signal resource associated with the CSI reporting configuration. Optionally, the reference signal resource associated with the activated TCI state can be determined based on the type of the reference signal resource associated with the CSI reporting configuration. Optionally, if the resource in the resource set is an SSB resource, the reference signal associated with the activated TCI state is determined using method #3. If the resource in the resource set is a CSI-RS resource (e.g., a reference signal resource with repeating parameters), the reference signal associated with the activated TCI state is determined based on method #4.

[0240] Optionally, the reference signals associated with the activated TCI states are of the same type. For example, one or more TCI states activated by MAC-CE signaling are associated with reference signals of the same type. Optionally, the type of the reference signals associated with the activated TCI states is the same as the type of the reference resources included in the resource set.

[0241] Optionally, the reference signal associated with the activated TCI state and the reference resource included in the resource set may be an SSB. Optionally, when the reference signal associated with the activated TCI state and / or the reference signal in the resource set is an SSB, the PCI of the SSB associated with the activated TCI state is the same as the PCI of the SSB in the resource set. This allows the UE to compare measurement results for SSBs from the same physical cell, so that the UE can initiate CSI reporting for that physical cell.

[0242] In some cases, a UE can be configured with one or more serving cells, each with different activated TCI states. It is necessary to specify which activated TCI state is used for event detection. The following methods can prevent the UE from initiating CSI using the wrong activated TCI state, thus improving the reliability of the communication system. Optionally, the activated TCI state is the activated TCI state associated with the second serving cell, or the activated TCI state is the activated TCI state associated with the second BWP in the second serving cell. For example, the activated TCI state used to initiate CSI (or, for reporting CSI, or for event determination, or for event association) could be: the activated TCI state associated with the second serving cell, or the activated TCI state associated with the second BWP in the second serving cell. Optionally, the second serving cell is indicated by the base station, or the second serving cell is predefined. For example, the second serving cell is indicated by a parameter (e.g., carrier) in the CSI reporting configuration. For example, when the CSI reporting configuration includes this parameter (e.g., carrier), the second serving cell is indicated by this parameter. For example, when the CSI reporting configuration does not include this parameter (e.g., carrier), the second serving cell is the serving cell where the CSI reporting configuration resides. For example, the second serving cell is the serving cell where a resource in the resource set resides. The method for determining the serving cell where a resource in the resource set resides is described above. Optionally, the second BWP can be indicated by the base station, or the second BWP can be a predefined BWP. For example, the second BWP is indicated by a parameter in the CSI reporting configuration. For example, when the CSI reporting configuration includes this parameter, the second BWP is indicated by this parameter. For example, when the CSI reporting configuration does not include this parameter, the second BWP is a predefined BWP. Optionally, the second BWP can be a BWP associated with a resource set. Optionally, the second BWP and the BWP associated with a resource set can be indicated by the same parameter. Optionally, the parameter used to indicate the second BWP may be the same as or different from the parameter used to indicate the second serving cell. For example, the ID of the second serving cell and the ID of the second BWP can be indicated by the parameter ServingCellAndBWP-Id. This parameter can be used to indicate the serving cell ID and the BWP ID. Here, the BWP can be a downlink BWP. Predefined BWPs can be: the active BWP, or the initial BWP, or the default BWP, or the BWP with the smallest ID, or the BWP with the largest ID.

[0243] In this document, the activated TCI state associated with the second serving cell refers to the activated TCI state on the second serving cell, or the activated TCI state applied / used on the second serving cell. In this document, the activated TCI state associated with the second BWP refers to the activated TCI state on the second BWP, or the activated TCI state applied / used on the second BWP.

[0244] Optionally, the activated TCI state refers to the most recent activated TCI state prior to the first uplink channel. For example, at least one activated TCI state among A activated TCI states (or, each activated TCI state) is the most recent activated TCI state prior to the first uplink channel. Optionally, the activated TCI state refers to the most recent activated TCI state prior to the reference resource associated with the first uplink channel. For example, at least one activated TCI state among A activated TCI states (or, each activated TCI state) is the most recent activated TCI state prior to the reference resource associated with the first uplink channel. Optionally, the activated TCI state refers to the most recent activated TCI state prior to the second uplink channel. For example, at least one activated TCI state among A activated TCI states (or, each activated TCI state) is the most recent activated TCI state prior to the second uplink channel. Optionally, the activated TCI state refers to the most recent activated TCI state prior to the CSI reference resource corresponding to the CSI report carried by the second uplink channel. For example, at least one of the A activated TCI states (or, each activated TCI state) is the most recent activated TCI state preceding the CSI reference resource corresponding to the second uplink channel. Since the activated TCI states are time-varying, this method can clearly identify which activated TCI states can be used for CSI initiation or event determination, preventing the UE from using incorrect activated TCI states to trigger CSI or determine events, thus improving UE reliability.

[0245] The UE can initiate the transmission of a first uplink channel and / or a second uplink channel. For example, the UE can transmit the first uplink channel and / or the second uplink channel to report CSI.

[0246] Optionally, the first uplink channel can be a PUCCH. Optionally, the resource corresponding to the first uplink channel can be a periodic PUCCH resource. Optionally, the format of the PUCCH can be PUCCH format 0 or PUCCH format 1. Optionally, the resource used to transmit the first uplink channel can be configured by the base station. Optionally, the CSI reporting configuration is used to indicate the resource for transmitting the first uplink channel. Optionally, the parameters included in the CSI reporting configuration (e.g., firstPUCCHResourceConfig-UEIBR-r19) can be used to indicate the resource for transmitting the first uplink channel. Optionally, this parameter includes at least one of the following: resource ID, resource-associated period, resource-associated offset, and BWP ID. For example, the transmission parameters corresponding to the resource of the first uplink channel can be determined by the configured resource ID. For example, the time-domain position corresponding to the transmission of the first uplink channel can be determined based on the resource-associated period and / or the resource-associated offset. For example, the transmission opportunity of the first uplink channel can be determined based on the resource association period and / or resource association offset.

[0247] Optionally, the BWP containing the resources of the first uplink channel can be predefined or indicated by the base station. Optionally, the BWP containing the resources of the first uplink channel can be indicated by parameters in the CSI reporting configuration. Optionally, the BWP containing the resources of the first uplink channel can be a predefined BWP. Optionally, this BWP is an uplink BWP. Optionally, the predefined BWP can be: an active BWP, or an initial BWP, or a default BWP, or the BWP with the smallest ID, or the BWP with the largest ID.

[0248] Optionally, the first uplink channel corresponds to a 1-bit indication. Optionally, the UE can indicate an information bit through the first uplink channel.

[0249] Optionally, the first uplink channel may be triggered by comparing the L1-RSRP of the reference signal resource associated with the indicated TCI state with a first threshold. Optionally, the first uplink channel may be triggered by comparing the difference between the L1-RSRP of the reference signal resource associated with the indicated TCI state and the L1-RSRP of resources in the resource set with a configured second threshold. Optionally, the first uplink channel may be triggered by comparing the difference between the L1-RSRP of the reference signal resource associated with the activated TCI state and the L1-RSRP of resources in the resource set with a configured third threshold. The reference signal associated with the activated TCI state may be: the reference signal with the Q-highest L1-RSRP among the reference signals associated with the activated TCI state, where Q≥1. Here, the activated TCI state may be one or more activated TCI states, wherein each activated TCI state is associated with a reference signal. Optionally, the second threshold and the third threshold may be indicated by the same parameter. Optionally, the L1-RSRP may be a measured L1-RSRP.

[0250] Optionally, the first uplink channel may be event-triggered. In this document, the term "event" may be used interchangeably with the terms "condition" or "condition of an event." An event may include at least one of the following: Type 1 event, Type 2 event, or Type 3 event. The event or event type may be predefined or indicated by the base station. For example, the event or event type may be indicated by a CSI reporting configuration. For example, the event or event type may be indicated by parameters included in the CSI reporting configuration (e.g., eventType-r19). For example, the base station may indicate at least one of Type 1, Type 2, and Type 3 events. Optionally, the UE may transmit the first uplink channel based on the indicated event. In this document, the quantity associated with the reference signal is exemplified by L1-RSRP. The quantity associated with the reference signal may also be of other types, such as L1-SINR, CQI, Reference Signal Received Quality (RSRQ), etc. In this document, the quantity may be referred to as an L1 quantity. In this document, the UE can obtain the quantity associated with the reference signal through measurement. The quantities obtained by the UE through measurement can be referred to as measured quantities. In this paper, the UE can report quantities related to the reference signal based on measurements of the reference signal to the base station. The quantities reported by the UE to the base station can be referred to as reported quantities.

[0251] Type 1 events are defined as follows: the L1-RSRP of the reference signal resource associated with the indicated TCI state is less than or equal to a first threshold. Optionally, the L1-RSRP of the reference signal resource can be the L1-RSRP of a transmission opportunity of the reference signal resource. Optionally, the L1-RSRP of the reference signal resource can be the L1-RSRP of at least one transmission opportunity of the reference signal resource. Optionally, the L1-RSRP can be a measured L1-RSRP. For example, the L1-RSRP is determined by measurement of the corresponding reference signal resource. Optionally, the first threshold can be an L1-RSRP threshold. Optionally, the first threshold corresponds to the L1-RSRP. Optionally, the first threshold can be predefined or indicated by the base station. For example, the first threshold can be indicated by a parameter in the CSI reporting configuration (e.g., eventThresholdEvent1-r19). For example, when this parameter is not configured in the CSI reporting configuration, the first threshold is determined based on the L1-RSRP threshold for beam failure recovery (or the L1-RSRP threshold for random access), or the first threshold is equal to the L1-RSRP threshold for beam failure recovery (or the L1-RSRP threshold for random access). Optionally, the L1-RSRP threshold for beam failure recovery can be a threshold used to determine whether a candidate beam is included in the MAC-CE reported by the UE. For example, when this parameter is not configured in the CSI reporting configuration, the first threshold is equal to the L1-RSRP threshold for beam failure recovery (e.g., rsrp-ThresholdSSB), or the L1-RSRP threshold for beam failure recovery (e.g., rsrp-ThresholdBFR). Optionally, the first threshold can be indicated by the parameter RSRP-Range. This parameter is used to indicate the value of L1-RSRP. The parameter RSRP-Range can be configured in the CSI reporting configuration. The L1-RSRP value corresponding to the first threshold can be (RSRP-Range-156) dBm or (RSRP-Range-140) dBm. Optionally, the RSRP-Range value is an integer between 16 and 113. For example, when the L1-RSRP value corresponding to the first threshold is (RSRP-Range-156) dBm, the RSRP-Range value is an integer between 16 and 113. Optionally, the RSRP-Range value is an integer between 0 and 97. For example, when the L1-RSRP value corresponding to the first threshold is (RSRP-Range-140) dBm, the RSRP-Range value is an integer between 0 and 97.

[0252] A Type 2 event can be defined as: the comparison between the L1-RSRP of at least one resource in the resource set and the L1-RSRP of the reference signal associated with the indicated TCI state is greater than or equal to a second threshold. For example, a Type 2 event can be defined as: the difference between the L1-RSRP of at least one resource in the resource set and the L1-RSRP of the reference signal associated with the indicated TCI state is greater than or equal to the second threshold. Optionally, the L1-RSRP of the reference signal resource can be the L1-RSRP of a transmission opportunity of the reference signal resource. Optionally, the L1-RSRP of the reference signal resource can be the L1-RSRP of at least one transmission opportunity of the reference signal resource. Optionally, the L1-RSRP can be a measured L1-RSRP. For example, this L1-RSRP is determined by measurement of the corresponding reference signal resource. Optionally, the second threshold can be an L1-RSRP threshold. Optionally, the second threshold corresponds to the L1-RSRP. Optionally, the second threshold can be predefined or indicated by the base station. For example, the second threshold can be indicated by a parameter in the CSI reporting configuration (e.g., eventThreshold-r19). Optionally, the unit of the second threshold is dB. Let the value of eventThreshold-r19 be y, then eventThreshold-r19 corresponds to y dB or S*y dB. y≥0, or y>0. S is a scaling factor. The value of S can be predefined. S>0. For example, S can be one of 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 8, or 16.

[0253] A Type 3 event can be defined as: the comparison between the L1-RSRP of at least one resource in the resource set and the L1-RSRP of the reference signal with the Q-highest L1-RSRP among the reference signals associated with the activated TCI state is greater than or equal to a third threshold. Optionally, the L1-RSRP of the reference signal resource can be the L1-RSRP of a transmission opportunity of the reference signal resource. Alternatively, the L1-RSRP of the reference signal resource can be the L1-RSRP of at least one transmission opportunity of the reference signal resource. For example, a Type 3 event can be defined as: the difference between the L1-RSRP of at least one resource in the resource set and the L1-RSRP of a specific activated TCI state associated with the reference signal is greater than or equal to a third threshold. The reference signal associated with the specific activated TCI state can be: the reference signal with the Q-highest L1-RSRP among the reference signals associated with the activated TCI state. Here, Q≥1. Optionally, the L1-RSRP can be the measured L1-RSRP. For example, this L1-RSRP is determined by measurement of the corresponding reference signal resource. Optionally, the third threshold can be an L1-RSRP threshold. Optionally, the third threshold corresponds to L1-RSRP. Optionally, the third threshold can be predefined or indicated by the base station. For example, the third threshold can be indicated by a parameter in the CSI reporting configuration (e.g., eventThreshold-r19). Optionally, the third threshold can be equal to the second threshold. Optionally, the third threshold can be indicated by the same parameter as the second threshold. Optionally, the unit of the third threshold is dB. Let the value of eventThreshold-r19 be y, then eventThreshold-r19 corresponds to y dB or S*y dB. y≥0, or y>0. S is a scaling factor. The value of S can be predefined. S>0. For example, S can be one of 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 8, 16. Optionally, the value of Q can be predefined or indicated by the base station. For example, Q can be indicated by the CSI reporting configuration. For example, Q can be indicated by a parameter (valueOfQ-r19) in the CSI reporting configuration. For example, when this parameter is not configured, the value of Q is 1. For example, when this parameter is not configured, the value of Q is equal to the number of activated TCI states. Optionally, Q can be a positive integer greater than or equal to 1. Optionally, Q ≤ 8. Optionally, Q is less than or equal to 8.

[0254] In this paper, a UE can have A TCI states activated, where A ≥ 1. For example, a UE can have A TCI states activated by MAC-CE. The number of activated TCI states can be represented by A.

[0255] Since the number of activated TCI states is determined based on the MAC-CE indication, and the value of Q is configured, in some cases, the number of activated TCI states may be less than the configured value of Q. In this situation, the UE's behavior is unclear, leading to the incorrect detection of corresponding events. The method proposed below can avoid the incorrect detection of events and improve the reliability of the communication system.

[0256] Optionally, Q (e.g., Q indicated by the base station) is less than or equal to the number of activated TCI states. Optionally, the number of activated TCI states is greater than or equal to Q (e.g., Q indicated by the base station). This method avoids situations where events cannot be detected due to the number of activated TCI states being less than Q, thus improving the reliability of the communication system. Optionally, Q is determined based on the base station's indication and the number of activated TCI states. Optionally, Q is equal to the smaller of the value indicated by the base station (e.g., the value indicated by valueOfQ-r19) and the number of activated TCI states. Optionally, when the number of activated TCI states is less than or equal to the value indicated by the base station (e.g., the value indicated by valueOfQ-r19), Q is equal to the number of activated TCI states. Optionally, when the number of activated TCI states is less than or equal to the value indicated by the base station (e.g., the value indicated by valueOfQ-r19), Q is equal to a predefined value. Optionally, this predefined value can be one of 1, 2, 3, 4, 5, 6, 7, or 8. Optionally, when the number of activated TCI states is greater than or equal to the value indicated by the base station (e.g., the value indicated by valueOfQ-r19), Q is equal to the value indicated by the base station. This method avoids situations where events cannot be detected due to the number of activated TCI states being less than the value of Q indicated by the base station, thus improving the reliability of the communication system.

[0257] Optionally, the UE may determine whether to transmit the first uplink channel based on the number of activated TCI states and / or the value of Q indicated by the base station. Optionally, the transmission of the first uplink channel is determined based on the number of activated TCI states and / or the value of Q indicated by the base station. Optionally, the UE transmits the first uplink channel when the number of activated TCI states is greater than or equal to the value of Q indicated by the base station. Optionally, the UE does not transmit the first uplink channel when the number of activated TCI states is less than or equal to the value of Q indicated by the base station. This method avoids uplink channel transmission when the number of activated TCI states is less than or equal to the value of Q indicated by the base station, thus saving UE power consumption.

[0258] Optionally, the UE may determine whether to evaluate an event based on the number of activated TCI states and / or the value of Q indicated by the base station. Event evaluation may be used to determine an event instance. The method for determining an event instance is described below. Optionally, the UE evaluates the event (or evaluates the indicated event) when the number of activated TCI states is greater than or equal to the value of Q indicated by the base station. Optionally, the UE does not evaluate the event (or does not evaluate the indicated event) when the number of activated TCI states is less than or equal to the value of Q indicated by the base station. This method can stop event evaluation when the number of activated TCI states is less than or equal to the value of Q indicated by the base station, saving UE power consumption.

[0259] In this paper, the term "number of TCI states" can be used interchangeably with the term "number of reference signals associated with TCI states".

[0260] The following further describes a method for the UE to determine whether to transmit the first uplink channel based on event detection. Optionally, the UE may determine whether to transmit the first uplink channel based on at least one of the following events.

[0261] Method #1: When an event (e.g., an indicated event) is determined, the UE may transmit a first uplink channel. The UE determines the transmission of the first uplink channel based on a measurement of the probability of the event-associated reference signal. Optionally, the probability of the reference signal refers to the probability of a reference signal no later than the reference resource associated with the first uplink channel. Optionally, the probability of the reference signal refers to the probability of the most recent reference signal no later than the reference resource associated with the first uplink channel. Optionally, the reference resource is no later than the first uplink channel. Optionally, the time-domain resource of the reference resource is determined based on the resource for transmitting the first uplink channel. For Type 1 events, the event-associated reference signal refers to the reference signal associated with the indicated TCI state. For Type 2 events, the event-associated reference signal refers to the reference signal associated with the indicated TCI state and / or the reference signal corresponding to the resources in the resource set (e.g., all resources). For Type 3 events, the event-associated reference signal refers to the reference signal associated with the activated TCI state (e.g., all activated TCI states) and / or the reference signal corresponding to the resources in the resource set (e.g., all resources). When multiple types of events are indicated, the reference signals associated with the multiple event types refer to the union of the reference signals associated with each of the multiple event types. Optionally, the event-associated reference signals have the same period. Optionally, the period of the reference signal resources associated with the CSI reporting configuration is the same as the period of the Z reference signal resources associated with the CSI reporting configuration. Optionally, the event-associated reference signals are configured with the same period. The above method can reserve processing time for the triggering of the first uplink channel by using reference resources, avoiding the situation where the UE cannot process the corresponding measurement results in time, thus improving the reliability of the communication system.

[0262] For example, the UE transmits a first uplink channel. The opportunity for a reference signal associated with an event that triggers the first uplink channel is no later than the reference resource associated with the first uplink channel. The opportunity for a reference signal associated with an event that triggers the first uplink channel is no later than the most recent measurement opportunity of the reference resource associated with the first uplink channel. The reference resource is no later than the first time-domain resource in which the first uplink channel resides. The reference resource can be determined based on the first time-domain resource. For example, the reference resource can be the first time-domain resource. For example, the offset between the time-domain cell in which the reference resource resides and the time-domain cell corresponding to the first time-domain resource can be predefined, based on UE capabilities, or indicated by the base station. For example, if the time-domain cell corresponding to the first time-domain resource is time-domain cell n, then the time-domain cell in which the reference resource resides is n-noffset. Optionally, the value of noffset is an integer. Optionally, noffset ≥ 0. Optionally, the value of noffset can be predefined. Optionally, the value of noffset can be determined based on UE capabilities. Optionally, the value of noffset can be indicated by the base station.

[0263] Method #2: Within a time window, when the number of event instances is greater than or equal to C, the UE may transmit a first uplink channel. Optionally, the length of this time window is indicated by the base station. For example, the length of the time window is indicated by a parameter in the CSI reporting configuration (e.g., eventDetectionTimeWindowLength-r19). Optionally, the end of the time window (or, the end time domain unit) is determined based on the second time domain resource where the first uplink channel resides. For example, the offset between the end of the time window (or, the end time domain unit) and the start of the first uplink channel (or, the start time domain unit) is indicated by the base station, predefined, or based on UE capabilities. For example, if the start time domain unit of the second time domain resource is time domain unit n, then the end time domain unit of the time window is n-n2offset. Optionally, the value of n2offset is an integer. Optionally, n2offset ≥ 0. Optionally, the value of n2offset can be predefined. Optionally, the value of n2offset can be determined based on UE capabilities. Optionally, the value of n2offset can be indicated by the base station. Optionally, C can represent the number of event instances within a time window that the UE can initiate a CSI report. Optionally, C can be indicated by the base station. Optionally, C ≥ 1. Optionally, C can be indicated by a parameter included in the CSI reporting configuration (e.g., eventInstanceCount-r19).

[0264] Optionally, within a time window, counting the determined event instance may be for the same reference signal (or the same indicated TCI state, or the same activated TCI state). For example, for a type 3 event, within a time window, counting the determined event instance may be for the same activated TCI state (or the reference signal corresponding to the same activated TCI state). For example, for type 2 and / or type 3 events, within a time window, counting the determined event instance may be for the same resource in the resource set (or the reference signal corresponding to the same resource), and / or for the same indicated TCI state (or the reference signal associated with the same indicated TCI state). For example, for a type 1 event, within a time window, counting the determined event instance may be for the same indicated TCI state (or the reference signal associated with the same indicated TCI state). Counting events for the same reference signal makes it easier for the UE to evaluate the direction corresponding to the reference signal, so that it can initiate CSI reporting in that direction in response to changes in channel state.

[0265] The UE can determine / evaluate events (or event instances). The UE can count event instances. The period for which an event instance is determined / counted / evaluated can be based on / equal to the period of a reference signal associated with the event. See above for the method of determining the reference signal associated with the event. The period for which an event instance is determined / counted / evaluated can be based on / equal to the largest (or smallest) period of the reference signal associated with the event.

[0266] Optionally, a time window may include one or more evaluation periods. Optionally, the one or more evaluation periods within a time window may be determined based on the period during which event instances are determined / counted / evaluated. When an event is determined within an evaluation period (e.g., when a corresponding condition is met within an evaluation period), the event is counted once within that evaluation period. For example, the corresponding counter is incremented once.

[0267] Optionally, the number of times an event is determined within a time window can be based on each transmission opportunity of the reference signal within that time window. For example, a time window may include M transmission opportunities of the reference signal, or the total number of transmission opportunities of the reference signal included in a time window may be M. For example, M ≥ 0. For example, if an event associated with N transmission opportunities is determined within a time window, then the number of times the event is determined within that time window is N. Optionally, N ≥ 0, and / or N ≤ M. For example, if N is greater than or equal to C, then the first uplink channel is triggered, or the UE transmits the first uplink channel. For example, if the number of events associated with each transmission opportunity of the reference signal is determined is greater than or equal to C, then the first uplink channel is triggered, or the UE transmits the first uplink channel. The definition of C is given above.

[0268] In this paper, an event is identified as follows: the conditions for the event are met, or the definition of the event is satisfied. Optionally, the identification of an event can be based on the evaluation of the event (or the conditions associated with the event instance). In this paper, an event instance is identified as follows: the conditions corresponding to the event instance are met, or the definition corresponding to the event instance is satisfied. Optionally, the identification of an event instance can be based on the evaluation of the event instance (or the conditions associated with the event instance).

[0269] In some cases, the transmission of the first uplink channel can be determined based on an indication of an activated TCI state (e.g., an indication of MAC-CE signaling). The method for indicating an activated TCI state is described above. When a Type 3 event is indicated, the UE can transmit the first uplink channel based on measurements of a reference signal associated with the (most recent) activated TCI state.

[0270] Optionally, the time-domain interval between the time-domain unit associated with the indication of the (most recently) activated TCI state and the time-domain unit associated with the first uplink channel is greater than or equal to a fourth threshold. Optionally, the UE transmits the first uplink channel when the time-domain interval between the time-domain unit associated with the indication of the (most recently) activated TCI state and the time-domain unit associated with the first uplink channel is greater than or equal to the fourth threshold. Optionally, the indication of the most recently activated TCI state refers to the indication of the most recently activated TCI state prior to the transmission of the first uplink channel. Optionally, the time-domain unit associated with the indication of the activated TCI state refers to the time-domain unit where the activated TCI state is applied, or the time-domain unit where the activated TCI state is effective. The application of the activated TCI state can be the application of the indication of the activated TCI state. The effectiveness of the activated TCI state can be the effectiveness of the indication of the activated TCI state. The time-domain unit where the activated TCI state is applied (or the activated TCI state takes effect) can be: the starting time-domain unit / first time-domain unit where the activated TCI state is applied (or the activated TCI state takes effect). Optionally, the time-domain resource associated with the first uplink channel can be: the time-domain unit associated with the first uplink channel. Optionally, the time-domain resource associated with the first uplink channel refers to: the time-domain resource / time-domain unit where the first uplink channel is transmitted. Optionally, the time-domain resource associated with the first uplink channel refers to: the time-domain resource where the first uplink channel is located, or the starting time-domain resource / ending time-domain resource of the first uplink channel. In this document, the time-domain interval between time-domain units can be: the offset between time-domain units. Optionally, the fourth threshold can be indicated by the base station, or the fourth threshold can be predefined, or the fourth threshold can be based on UE capabilities. Optionally, the unit of the fourth threshold can be a symbol / time slot. Optionally, the fourth threshold can be an integer greater than or equal to 1.

[0271] Optionally, when an indication of an activated TCI state is received (or applied) within the time window, the corresponding first uplink channel is not transmitted. Optionally, if no indication of an activated TCI state is received within the time window, or no indication of an activated TCI state is applied within the time window, the first uplink channel may be transmitted.

[0272] Optionally, the count of event instances can be determined based on an indication of an activated TCI state. For example, a counter used to count event instances can be reset by an indication of an activated TCI state. For example, the counter is reset when the UE receives an indication of an activated TCI state. For example, the counter is reset when the indication of an activated TCI state takes effect. When the value of the counter is greater than or equal to C, the UE can trigger the first uplink channel.

[0273] The above method allows the UE sufficient time to measure the reference signal associated with the activated TCI state when the activated TCI state changes due to the corresponding indication.

[0274] Optionally, the second uplink channel can be a PUSCH. Optionally, the second uplink channel can be used to carry CSI reporting. Optionally, the second uplink channel can be used to carry beam reporting.

[0275] Optionally, the resources used to transmit the second uplink channel can be dynamically scheduled. Optionally, the resources corresponding to the second uplink channel can be indicated by a DCI. For example, the DCI can be DCI format 0_1 / 0_2.

[0276] Optionally, the resources used to transmit the second uplink channel can be configured by the base station. Optionally, the CSI reporting configuration is used to indicate the resources for transmitting the second uplink channel. Optionally, parameters included in the CSI reporting configuration (e.g., configuredResourceForSecondChannelOfModeB-r19) can be used to indicate the resources for transmitting the second uplink channel. Optionally, the second uplink channel can be a configuration grant-based PUSCH. Optionally, the second uplink channel is associated with a configuration grant configuration. Optionally, the configuration grant configuration is a type 1 configuration grant. Optionally, the UE can transmit the second uplink channel based on the configuration grant configuration. Optionally, the UE can transmit the second uplink channel based on the resources indicated by the configuration grant configuration. Optionally, parameters included in the CSI reporting configuration can indicate the ID of the configured grant configuration. This parameter can also indicate the serving cell and / or BWP where the configuration grant configuration resides. Optionally, the BWP is an uplink BWP.

[0277] Optionally, the UE expects the BWP associated with / configured by the configuration license configuration to be an active BWP. This method avoids the second uplink channel from being unable to be transmitted due to BWP deactivation being paused, thus improving the reliability of the communication system.

[0278] Optionally, the UE can determine whether to transmit the first uplink channel based on the BWP configured by the configuration permission configuration. Optionally, the UE can determine whether to transmit the first uplink channel based on whether the BWP configured by the configuration permission configuration is an active BWP. Optionally, if the BWP containing the configuration permission configuration is not an active BWP, the UE will not transmit the first uplink channel and / or the second uplink channel. Optionally, if the BWP containing the configuration permission configuration is an active BWP, the UE can transmit the first uplink channel and / or the second uplink channel. Optionally, the first uplink channel and / or the second uplink channel and / or the configuration permission configuration correspond to the same CSI reporting configuration. Optionally, when the BWP containing the configuration permission configuration is not an active BWP, the CSI reporting configuration associated with / corresponding to the configuration permission configuration can be suspended. Optionally, when the BWP containing the configuration permission configuration is not an active BWP, the event evaluation (or event-related measurement, or event counting, or event determination) associated with / corresponding to the CSI reporting configuration can be suspended. Optionally, when the BWP containing the configuration permission configuration is not an active BWP, the configuration permission configuration can be suspended. Optionally, this method applies to Type 2 events and / or Type 3 events. Optionally, this method applies to Mode B. See below for a description of Mode B. This method can prevent the associated first / second uplink channel from being triggered / transmitted when the configuration permission configuration is suspended and the second uplink channel cannot be transmitted, thus saving UE power consumption.

[0279] In this document, the term "pause" may be used interchangeably with the terms "deactivate" or "stop". The term "activate" may be used interchangeably with the terms "resume" or "start".

[0280] Optionally, the configuration permission setting can indicate the period used for uplink transmission. For example, the configuration permission setting can indicate the period for transmission opportunities to transmit a second uplink channel. Optionally, this period can be the same as the period associated with the first uplink channel (e.g., the period of the PUCCH resource).

[0281] Optionally, the transmission of the first uplink channel and / or the second uplink channel can be based on mode A or mode B. A CSI reporting configuration can be associated with mode A or mode B. Optionally, the mode that a CSI reporting configuration can be associated with can be determined based on whether the CSI reporting configuration includes parameters for configuring resources for the second uplink channel (e.g., configuredResourceForSecondChannelOfModeB-r19). For example, if the CSI reporting configuration does not include parameters for configuring resources for the second uplink channel, then the CSI reporting configuration corresponds to mode A. For example, if the CSI reporting configuration includes parameters for configuring resources for the second uplink channel, then the CSI reporting configuration corresponds to mode B. Optionally, the mode that a CSI reporting configuration can be associated with can be indicated by a parameter in the CSI reporting configuration (e.g., reportTransmissionMode-r19). This parameter can indicate (e.g., explicitly indicate) one of mode A and mode B.

[0282] Mode A includes at least one of the following steps: Step 1: The UE transmits a first uplink channel; Step 2: The UE detects a DCI, wherein the DCI indicates resources for a second uplink channel; Step 3: The UE transmits a second uplink channel.

[0283] In mode A, the first uplink channel can be used to request resources for the second uplink channel. For example, the UE can send the first uplink channel to the base station to request resources for the second uplink channel used to send CSI reports.

[0284] For Mode A, the UE receives / listens to PDCCH candidates (for detecting DCI). Optionally, the UE can receive / detect a DCI indicating resources of a second uplink channel. Optionally, the second uplink channel is used to carry CSI reporting. Optionally, the DCI is associated with a first uplink channel. Optionally, the DCI can trigger / indicate a CSI triggering state. Optionally, the CSI triggering state can be an aperiodic CSI triggering state. Optionally, the CSI triggering state can indicate one or more CSI reporting configurations. Optionally, the one or more CSI reporting configurations include the CSI reporting configuration associated with the first uplink channel. Optionally, the DCI is a feedback to the first uplink channel. Optionally, the DCI can be DCI format 0_1 ​​or 0_2.

[0285] Mode B includes at least one of the following steps: Step 1: The UE transmits a first uplink channel; Step 2: The UE transmits a second uplink channel.

[0286] For Mode B, the first uplink channel can indicate / notify the second uplink channel (e.g., the second uplink channel carrying CSI reporting). For example, the UE can send the first uplink channel to the base station to notify the base station that the UE will send the second uplink channel carrying CSI reporting.

[0287] For Mode B, the second uplink channel can carry CSI reporting associated with the CSI reporting configuration. Optionally, the second uplink channel can be determined based on the first uplink channel. Optionally, the resources of the second uplink channel are determined based on the first uplink channel. Optionally, the transmission opportunity of the second uplink channel is determined based on the first uplink channel. Optionally, the UE transmits the second uplink channel on the first transmission opportunity after X symbols following the last symbol of the first uplink channel. Optionally, the UE will transmit the first uplink channel (UE would transmit the first UL channel), and the UE will transmit the second uplink channel on the first transmission opportunity after X symbols following the last symbol of the first uplink channel. Optionally, the UE transmitting the first uplink channel can be: the UE is indicated to transmit the first uplink channel (UE is indicated to transmit the first UL channel), or the UE is to transmit the first uplink channel (UE is to transmit the first UL channel). Optionally, if the information associated with the first uplink channel (e.g., UCI) is multiplexed in the third uplink channel, the UE will transmit the second uplink channel on the first transmission opportunity after X symbols following the last symbol of the third uplink channel. Optionally, the third uplink channel can be PUCCH or PUSCH. Optionally, the third uplink channel can be a different channel from the first uplink channel. The above method can clearly determine whether the reference point of X symbols is based on the first uplink channel before UCI multiplexing or on the third uplink channel after UCI multiplexing, avoiding the UE from transmitting the second uplink channel based on an incorrect reference point and improving the reliability of the communication system. Optionally, the third uplink channel can include / correspond to / associate with one or more repetitions. The last symbol of the third uplink channel can be: the last symbol of the last repetition in one or more repetitions associated with the third uplink channel. Optionally, the value of X can be indicated by the base station, or the value of X is predefined, or the value of X is based on the UE capability. The value of X can be an integer greater than or equal to 0. Optionally, the subcarrier spacing of the X symbols (the subcarrier spacing corresponding to X) is determined based on the subcarrier spacing of the first uplink channel and / or the subcarrier spacing of the second uplink channel. For example, the subcarrier spacing of the X symbols is equal to the subcarrier spacing of the first uplink channel. For example, the subcarrier spacing of the X symbols is equal to the subcarrier spacing of the second uplink channel. For example, the subcarrier spacing of the X symbols is equal to the larger / smaller value of the subcarrier spacing of the first uplink channel and the subcarrier spacing of the second uplink channel. This method can prevent the UE from using incorrect subcarrier spacing to determine the transmission opportunity of the second uplink channel, thus improving the reliability of the communication system.

[0288] Optionally, the first transmission opportunity may be the first available transmission opportunity. A transmission opportunity may be considered available if at least one of the following conditions is met: 1) the transmission opportunity is not in a measurement gap; 2) the transmission opportunity does not include downlink symbols, or the transmission opportunity includes uplink symbols and / or flexible symbols, or the transmission opportunity only includes uplink symbols and / or flexible symbols. Optionally, the uplink symbols and / or flexible symbols and / or downlink symbols are configured by higher-layer signaling (e.g., configuration information for configuring TDD); 3) the transmission opportunity does not include symbols for receiving SSBs. A transmission opportunity may be considered invalid if at least one of the following conditions is met: 1) the transmission opportunity is in a measurement gap; 2) the transmission opportunity includes downlink symbols, or the transmission opportunity does not include uplink symbols and / or flexible symbols. Optionally, the downlink symbols are configured by higher-layer signaling (e.g., configuration information for configuring TDD); 3) the transmission opportunity includes symbols for receiving SSBs.

[0289] Optionally, the subcarrier spacing of the first uplink channel refers to the subcarrier spacing used for transmitting the first uplink channel. Optionally, the subcarrier spacing of the first uplink channel is the subcarrier spacing of the uplink BWP to which it resides. Optionally, the subcarrier spacing of the second uplink channel refers to the subcarrier spacing used for transmitting the second uplink channel. Optionally, the subcarrier spacing of the second uplink channel is the subcarrier spacing of the uplink BWP to which it resides. In this document, the term "subcarrier spacing" can be used interchangeably with "subcarrier spacing configuration".

[0290] Optionally, the first uplink channel may correspond to one or more repetitions. For example, the first uplink channel may correspond to one or more PUCCH repetitions. The last symbol of the first uplink channel may be the last symbol of the last repetition (or the last symbol of the first repetition) in one or more repetitions.

[0291] The following discussion covers the content of CSI reports (e.g., CSI reports carried by the second uplink channel, or CSI reports initiated by the UE). In this text, UE-reported CSIs are exemplified by CRI, SSBRI, and L1-RSRP, but this is not a limitation. UE-reported CSIs can also be other types, such as SINR and CQI. In this paper, the UE-reported L1-RSRP can be referred to as: Reported L1-RSRP.

[0292] The L1-RSRP reported by the UE can be either absolute L1-RSRP or differential L1-RSRP.

[0293] The absolute L1-RSRP is determined based on the measured L1-RSRP. The measured L1-RSRP can be quantized into the absolute L1-RSRP value. The absolute L1-RSRP value is a 7-bit value. The absolute L1-RSRP value ranges from -140 dBm to -44 dBm. The step size corresponding to the absolute L1-RSRP value is 1 dB. The mapping relationship between the absolute L1-RSRP value and the measured L1-RSRP is shown in Table 1 below. Optionally, the first code point of the absolute L1-RSRP value can correspond to RSRP_16. The second code point of the absolute L1-RSRP value can correspond to RSRP_17, and so on. Optionally, the first code point of the absolute L1-RSRP value can correspond to RSRP_113. The second code point of the absolute L1-RSRP value can correspond to RSRP_112, and so on. In Table 1, RSRP_x corresponds to the value x. For example, RSRP_0 corresponds to the value 0. Optionally, the 17th code point of the absolute L1-RSRP value can correspond to RSRP_16.

[0294] The 18th code point of the absolute L1-RSRP value can correspond to RSRP_17, and so on.

[0295]

[0297]

[0298] Table 1

[0299] The differential L1-RSRP can be determined based on the measured L1-RSRP and the reference L1-RSRP. The difference between the measured L1-RSRP and the reference L1-RSRP can be quantized into the value of the differential L1-RSRP. The value of the differential L1-RSRP is a 4-bit value. The step size corresponding to the value of the differential L1-RSRP is 2dB. The mapping relationship between the value of the differential L1-RSRP and the difference between the measured L1-RSRP and the reference L1-RSRP is shown in Table 2 below. ΔRSRP represents the difference in L1-RSRP. Optionally, the first code point of the differential L1-RSRP value can correspond to DIFFRSRP_0. The second code point of the differential L1-RSRP value can correspond to DIFFRSRP_1, and so on. Optionally, the first code point of the differential L1-RSRP value can correspond to DIFFRSRP_15. The second code point of the differential L1-RSRP value can correspond to DIFFRSRP_14, and so on. Optionally, in Table 2, the value corresponding to DIFFRSRP_x is x. For example, the value corresponding to DIFFRSRP_0 is 0.

[0302] Table 2

[0303] The UE can report the L1-RSRP of the reference signal resource associated with the indicated TCI state. When a Type 1 event is configured, the UE can report the L1-RSRP of the reference signal resource associated with the indicated TCI state. This L1-RSRP is obtained through measurement of the reference signal resource associated with the indicated TCI state. Optionally, the L1-RSRP can be an absolute L1-RSRP or a differential L1-RSRP. Optionally, whether the L1-RSRP is an absolute L1-RSRP or a differential L1-RSRP can be determined by indication from the base station or based on UE capabilities. Optionally, whether the L1-RSRP is a differential L1-RSRP can be determined by indication from the base station or based on UE capabilities. For example, the CSI reporting configuration may include parameters for indicating whether the L1-RSRP is an absolute L1-RSRP or a differential L1-RSRP. For example, the CSI reporting configuration may include parameters for indicating whether the L1-RSRP is a differential L1-RSRP. For example, if the UE supports the L1-RSRP as a differential L1-RSRP, then the UE reports the differential L1-RSRP corresponding to the L1-RSRP. For example, if the UE does not support the L1-RSRP as a differential L1-RSRP, then the UE reports the absolute L1-RSRP corresponding to the L1-RSRP.

[0304] Optionally, the differential L1-RSRP can be determined based on the difference between the reference L1-RSRP and the measured L1-RSRP. Optionally, the reference L1-RSRP can be indicated by the base station, or the reference L1-RSRP can be predefined, or the reference L1-RSRP can be determined based on the highest measured L1-RSRP reported. Optionally, the reference L1-RSRP is a predefined L1-RSRP. The unit of L1-RSRP can be dBm. A predefined L1-RSRP can be Z dBm, where Z is an integer. Optionally, the reference L1-RSRP can be indicated by the CSI reporting configuration. Optionally, the reference L1-RSRP can be determined based on a first threshold. Optionally, the reference L1-RSRP can be the L1-RSRP corresponding to the first threshold. The description of the first threshold is given above. Based on the definition of Type 1 events, it can be known that the measured L1-RSRP of the reference signal resource associated with the indicated TCI state is less than or equal to the first threshold. Therefore, the UE can perform differential L1-RSRP reporting and set the reference L1-RSRP as the L1-RSRP corresponding to the first threshold, thereby reducing the overhead of CSI reporting.

[0305] The UE can report the L1-RSRP of resources in the resource set. Optionally, the UE can report the L1-RSRP of N reference signal resources. When a Type 1 event is configured, the UE can report the L1-RSRP of N reference signal resources. In a CSI reporting instance, the UE can report the L1-RSRP of N reference signal resources and / or the L1-RSRP of reference signal resources associated with the indicated TCI state. The description of N is given below. The L1-RSRP of N reference signal resources refers to: the L1-RSRP of each of the N reference signal resources, or N L1-RSRPs of each of the N reference signal resources.

[0306] The UE can be configured to report a number (N) of reference signal resources, where N ≥ 1. Optionally, the reference signal resources are resources in a resource set. Optionally, N ≤ N_max, where N_max is determined based on the UE's capabilities. Optionally, N_max represents the maximum number of reference signal resources the UE supports for reporting, as indicated by the UE's capabilities. Optionally, N_max represents the number of resources in the maximum resource set the UE supports for reporting, as indicated by the UE's capabilities. Optionally, N can be predefined or indicated by the base station. For example, N can be indicated by a parameter in the CSI reporting configuration (e.g., nrofReportedRS-UEIBR-r19). The value of N can be one of 1, 2, 3, or 4. Optionally, at least one of type 1 events, type 2 events, and type 3 events can be configured with N.

[0307] The UE can report the L1-RSRP of N reference signal resources and the L1-RSRP of the reference signal resources associated with the indicated TCI state.

[0308] Optionally, if the event associated with the CSI reporting configuration is a Type 1 event, then the L1-RSRP of the reference signal associated with the indicated TCI state in the CSI reporting configuration satisfies the Type 1 event (or satisfies the conditions corresponding to the Type 1 event). Alternatively, if the event associated with the CSI reporting configuration is a Type 1 event, then the reference signal resource associated with the indicated TCI state in the CSI reporting configuration satisfies the Type 1 event (or satisfies the conditions corresponding to the Type 1 event). For example, the measured L1-RSRP of the reference signal associated with the indicated TCI state is less than or equal to a first threshold.

[0309] In some cases, a UE can acquire / receive / be configured with L CSI reporting configurations. Here, L ≥ 1, or L > 1. L can be an integer greater than or equal to 1. Optionally, at least one (or each) of the L CSI reporting configurations is a CSI reporting configuration used for UE-initiated CSI reporting. A description related to UE-initiated CSI reporting can be found above.

[0310] Optionally, at least one (or each) of the L CSI reporting configurations may indicate an ID used to identify that CSI reporting configuration (e.g., CSI reporting configuration ID, or CSI-ReportConfigId).

[0311] Optionally, at least one (or each) of the L CSI reporting configurations may indicate the resources used to transmit the first uplink channel.

[0312] To conserve the resources reserved by the base station for transmitting the first uplink channel, L CSI reporting configurations can share / indicate / associate the same resources for transmitting the first uplink channel. In this document, "resources for transmitting the first uplink channel" can be used interchangeably with "resources for the first uplink channel" or "resources for transmitting the first uplink channel." Optionally, the resources associated with the first uplink channel in the L CSI reporting configurations are the same. Optionally, the same resources associated with the first uplink channel in the L CSI reporting configurations include at least one of the following: 1) the parameters of the resources used to indicate the first uplink channel included in the L CSI reporting configurations are the same; 2) the IDs of the resources included / indicated in the L CSI reporting configurations are the same; 3) the periods and / or offsets associated with the resources included / indicated in the L CSI reporting configurations are the same; 4) the BWPs associated with the resources included / indicated in the L CSI reporting configurations are the same. In this document, "same resources" can mean the same resource ID. In this document, "same BWPs" can mean the same BWP ID. In this paper, the BWP associated with the resources of the first uplink channel can be: the BWP where the resources of the first uplink channel are located.

[0313] The UE can transmit a first uplink channel. Optionally, this first uplink channel is determined based on a first CSI reporting configuration among L CSI reporting configurations. Optionally, this first uplink channel is initiated based on a first CSI reporting configuration among L CSI reporting configurations. Optionally, the transmission of this first uplink channel is based on a first CSI reporting configuration among L CSI reporting configurations. Optionally, this first uplink channel is triggered by an event associated with a first CSI reporting configuration among L CSI reporting configurations. Optionally, the first CSI reporting configuration is selected by the UE from L CSI reporting configurations.

[0314] Optionally, the first uplink channel is associated with L CSI reporting configurations. For example, the UE can transmit the first uplink channel on the same resources (e.g., resources used for transmitting the first uplink channel) associated with each of the L CSI reporting configurations. Optionally, associating the first uplink channel with the L CSI reporting configurations includes: the resources for transmitting the first uplink channel are associated with the L CSI reporting configurations. Optionally, the resources for transmitting the first uplink channel are the same as the resources associated with the L CSI reporting configurations. Optionally, the fact that the resources of the first uplink channel being transmitted are the same as the resources associated with the L CSI reporting configurations includes at least one of the following: 1) the ID of the resources of the first uplink channel being transmitted is the same as the ID of the resources of the first uplink channel included / indicated in the L CSI reporting configurations; 2) the period and / or offset of the resources of the first uplink channel being transmitted is the same as the period and / or offset associated with the resources of the first uplink channel included / indicated in the L CSI reporting configurations; 3) the BWP of the first uplink channel being transmitted is the same as the BWP associated with the resources of the first uplink channel included / indicated in the L CSI reporting configurations.

[0315] The UE can transmit a second uplink channel associated with the first uplink channel. The second uplink channel includes / carries CSI reporting. Optionally, the CSI reporting in the second uplink channel can be determined based on one of L CSI reporting configurations. Optionally, the CSI reporting in the second uplink channel can be determined based on the first CSI reporting configuration. Optionally, the CSI reporting in the second uplink channel corresponds to / is associated with the first CSI reporting configuration.

[0316] Optionally, the CSI reporting included / carried in the second uplink channel may include / indicate the first CSI reporting configuration. Optionally, the CSI reporting may include a CSI reporting configuration indicator. This CSI reporting indicator indicates one of L CSI reporting configurations. Optionally, the CSI reporting configuration indicated by the CSI reporting configuration indicator is the first CSI reporting configuration. The size of the CSI field corresponding to the CSI reporting configuration indicator is determined based on L. For example, the size of the CSI field is... Alternatively, log2L. For example, the value k (k≥0) of the CSI field corresponds to the (k+1)th CSI report in L CSI reporting configurations. Optionally, the order of the L CSI reporting configurations is determined based on the IDs of the L CSI reporting configurations. Optionally, the order of the L CSI reporting configurations is based on ascending / descending order of the IDs of the L CSI reporting configurations. For example, the (k+1)th CSI report in L CSI reporting configurations refers to the CSI reporting configuration with the (k+1)th smallest ID value among the L CSI reporting configurations. For example, the first CSI reporting configuration in L CSI reporting configurations refers to the CSI reporting configuration with the smallest ID among the L CSI reporting configurations.

[0317] Since the first CSI reporting configuration is determined by the UE, it cannot be known by the base station before demodulating the second uplink channel. For example, when L>1, the base station cannot know which of the L CSI reporting configurations the first CSI reporting configuration is before demodulating the second uplink channel. To avoid the base station attempting to receive the second uplink channel based on assumptions about each of the L CSI reporting configurations, and / or to avoid the base station receiving / decoding based on incorrect CSI reporting configurations, configuration restrictions / operations need to be applied to the L CSI reporting configurations. This ensures that the second uplink channels corresponding to the L CSI reporting configurations can be transmitted using the same resources, saving the base station's receiving / detection overhead and improving the reliability of the communication system. The configuration restrictions / operations related to the L CSI reporting configurations are discussed below.

[0318] Optionally, the resources for the second uplink channel associated with the L CSI reporting configurations are the same. In this document, "resources used for transmitting the second uplink channel" can be used interchangeably with "resources for the second uplink channel" or "resources used for transmitting the second uplink channel." Optionally, the configuration information for the second UL channel associated with the L CSI reporting configurations are the same. Optionally, the configuration information associated with the second uplink channel in the L CSI-reported configurations being identical includes at least one of the following: 1) the parameters for configuring / indicating the resources of the second uplink channel included in the L CSI-reported configurations are identical; 2) the configuration permission configurations included / indicated in the L CSI-reported configurations are identical (e.g., the configuration permission configuration IDs are identical); 3) the BWPs associated with the configuration permission configurations included / indicated in the L CSI-reported configurations are identical (e.g., the BWP IDs associated with the configuration permission configurations are identical); 4) the serving cells associated with the configuration permission configurations included / indicated in the L CSI-reported configurations are identical (e.g., the serving cell IDs associated with the configuration permission configurations are identical); 5) the X included / indicated in the L CSI-reported configurations are identical (e.g., the values ​​of X are identical). The indication method and related description of X are described above. Optionally, X may represent the time offset for determining the available transmission occasion of the second channel from the first channel between the first uplink channel and the first available transmission opportunity for the second uplink channel. In this document, identical X may mean that the value of the time offset represented by X is identical. In this document, the BWP associated with the configuration license configuration can be the BWP where the configuration license configuration resides. Similarly, the serving cell associated with the configuration license configuration can be the serving cell where the configuration license configuration resides.

[0319] Optionally, the L CSI configuration reports are associated with the same event type. For example, all L CSI configuration reports are associated with type 1 events. For example, all L CSI configuration reports are associated with type 2 events. For example, all L CSI configuration reports are associated with type 3 events.

[0320] Optionally, the L CSI reporting configurations can correspond to L time offsets. See above for a description of the time offsets. Optionally, the time offset associated with the CSI reporting carried by the second uplink channel is determined based on the L CSI reporting configurations. For example, the time offset associated with the CSI reporting carried by the second uplink channel is equal to the maximum / minimum / average of the time offsets associated with each of the L CSI reporting configurations. For example, the time offset associated with the l-th CSI reporting configuration in the L CSI reporting configurations is X. l Here, l ≥ 1 and or l ≤ L. The time offset associated with the CSI reporting carried by the second uplink channel can be represented as X. max .

[0321] For example, For example, Where Q represents a set including 1, 2, ..., L.

[0322] Optionally, the time domain positions of the time windows associated with the L CSI reporting configurations are the same. For example, the time domain positions of the L time windows associated with the L CSI reporting configurations are the same. Optionally, the time domain positions of the time windows being the same can be at least one of the following: 1) the starting time domain unit of the time window is the same; 2) the ending time domain unit of the time window is the same; 3) the length of the time window is the same.

[0323] Optionally, the L CSIs report the reference signal resources associated with the configuration at the same period. Optionally, the L CSIs report the reference signal resources associated with each configuration at the same period. Optionally, the reference signal resources associated with the configuration reported by the CSI include at least one of the following: 1) reference signal resources in the resource set associated with the configuration reported by the CSI; 2) reference signal resources associated with the indicated TCI state associated with the configuration reported by the CSI; 3) reference signal resources associated with the activated TCI state associated with the configuration reported by the CSI. Optionally, the reference signal resources associated with the configuration reported by the L CSIs include at least one of the following: 1) reference signal resources in the resource set associated with each configuration reported by the L CSIs; 2) reference signal resources associated with the indicated TCI state associated with each configuration reported by the L CSIs; 3) reference signal resources associated with the activated TCI state associated with each configuration reported by the L CSIs.

[0324] Optionally, the L CSI-reported configurations are associated with the same mode type. Alternatively, the L CSI-reported configurations are each associated with the same mode type.

[0325] To prevent base stations from receiving / decoding CSI reports based on incorrect priority, it is necessary to clearly define the priority of CSI reports so that the UE and base station have the same understanding of the CSI reporting priority, thereby improving the reliability of the communication system. The following discusses the method for determining the priority of CSI reports in the second uplink channel. In the following description, the priority of CSI reports in the second uplink channel refers to the priority of CSI reports in the second uplink channel relative to the priority of other CSI reports. In this paper, other CSI reports can be other CSI reports carried in the second uplink channel, or, other CSI reports can be CSI reports carried in other uplink channels different from the second uplink channel.

[0326] Optionally, the priority of CSI reporting in the second uplink channel can be determined based on the first CSI reporting configuration. Optionally, for example, the priority of CSI reporting in the second uplink channel is equal to the priority associated with the first CSI reporting configuration. For example, when L=1, the priority of CSI reporting in the uplink channel is equal to the priority associated with the CSI reporting configuration / first CSI reporting configuration. Since only one CSI reporting configuration exists when L=1, the base station knows that the UE will use this CSI reporting configuration (i.e., the first CSI reporting configuration) for CSI reporting. Therefore, the priority of CSI reporting can be determined based on this CSI reporting configuration (i.e., the first CSI reporting configuration), avoiding the base station determining the corresponding CSI reporting priority based on an incorrect CSI reporting configuration and improving the reliability of the communication system.

[0327] In this document, the term "priority" is used interchangeably with the term "priority value." The term "priority value associated with a CSI reporting configuration" is used interchangeably with the terms "CSI report priority value" or "priority value associated with the CSI report corresponding to the CSI reporting configuration." In this document, when L > 1, it can be assumed that L CSI reporting configurations correspond to multiple CSI reporting configurations. When L = 1, it can be assumed that L CSI reporting configurations correspond to one CSI reporting configuration.

[0328] Optionally, the priority of CSI reporting in the second uplink channel can be predefined or indicated by the base station. Optionally, when L>1, the priority of CSI reporting in the second uplink channel can be predefined or indicated by the base station.

[0329] Optionally, the predefined priority of CSI reporting in the second uplink channel may include at least one of the following: 1) the priority value of CSI reporting in the second uplink channel is a predefined value (e.g., this value may be an integer greater than or equal to 0); 2) the priority of CSI reporting in the second uplink channel in the case of L>1 is different from (e.g., lower / higher than) the priority of CSI reporting in the second uplink channel in the case of L=1.

[0330] Optionally, the priority of CSI reporting in the second uplink channel, as indicated by the base station, may include: the value of the priority of CSI reporting in the second uplink channel being a value indicated by the base station. For example, this value may be an integer greater than or equal to 0. For example, at least one of the L CSI reporting configurations indicates this value. For example, each of the L CSI reporting configurations indicates this value. For example, each of the L CSI reporting configurations indicates this value, and the value indicated by each CSI reporting configuration is the same.

[0331] Optionally, the priority of CSI reporting in the second uplink channel can be determined based on L CSI reporting configurations. Optionally, when L>1, the priority of CSI reporting in the second uplink channel can be determined based on L CSI reporting configurations. Here, determining based on CSI reporting configurations can include: determining based on priorities associated with CSI reporting configurations. Optionally, the priority of CSI reporting in the second uplink channel can be determined based on a predefined value among the priority values ​​associated with each of the L CSI reporting configurations. Optionally, the predefined value can be at least one of the following: maximum value; minimum value; first value; last value. For example, the priority of CSI reporting in the second uplink channel can be the maximum / minimum value among the priority values ​​associated with each of the L CSI reporting configurations. Optionally, the priority of CSI reporting in the second uplink channel can be determined based on the average value of the priority values ​​associated with each of the L CSI reporting configurations. For example, the priority of CSI reporting in the second uplink channel is the average (rounded up or down) of the L priority values ​​associated with each of the L CSI reporting configurations. Optionally, the priority of CSI reporting in the second uplink channel can be determined based on the sum of the priority values ​​associated with each of the L CSI reporting configurations. For example, the priority of CSI reporting in the second uplink channel is the sum of the L priority values ​​associated with each of the L CSI reporting configurations.

[0332] Optionally, the priority of CSI reporting in the second uplink channel can be determined based on the second CSI reporting configuration among L CSI reporting configurations. Optionally, when L>1, the priority of CSI reporting in the second uplink channel can be determined based on the second CSI reporting configuration among L CSI reporting configurations. Here, determining based on the CSI reporting configuration can include: determining based on the priority associated with the CSI reporting configuration. Optionally, the second CSI reporting configuration can be predefined. For example, the second CSI reporting configuration can include at least one of the following: 1) the first CSI reporting configuration among L CSI reporting configurations, or the last CSI reporting configuration among L CSI reporting configurations; 2) the CSI reporting configuration with the lowest ID value among L CSI reporting configurations, or the CSI reporting configuration with the highest ID value among L CSI reporting configurations; 3) the CSI reporting configuration with the lowest associated priority value among L CSI reporting configurations, or the CSI reporting configuration with the highest associated priority value among L CSI reporting configurations.

[0333] Optionally, the second CSI reporting configuration can be indicated by the base station.

[0334] Optionally, the second CSI reporting configuration is indicated by RRC. Optionally, RRC can indicate which of the L CSI reporting configurations the second CSI reporting configuration is. For example, the RRC signaling can be a higher-layer parameter indicating a value v, where v ≥ 0. v corresponds to the (v+1)th CSI reporting configuration among the L CSI reporting configurations. Optionally, RRC can indicate whether the second CSI reporting configuration is the CSI reporting configuration with the lowest corresponding CSI reporting configuration ID value or the CSI reporting configuration with the highest corresponding CSI reporting configuration ID value among the L CSI reporting configurations. For example, when the RRC-indicated value v equals a first value (e.g., 0), the second CSI reporting configuration is the CSI reporting configuration with the lowest corresponding CSI reporting configuration ID value among the L CSI reporting configurations. When the RRC-indicated value v equals a second value (e.g., 1), the second CSI reporting configuration is the CSI reporting configuration with the highest corresponding CSI reporting configuration ID value among the L CSI reporting configurations. Optionally, the RRC can indicate whether the second CSI reporting configuration is the CSI reporting configuration with the lowest corresponding priority value among the L CSI reporting configurations or the CSI reporting configuration with the highest corresponding priority value. For example, when the value v indicated by the RRC is equal to a first value (e.g., 0), the second CSI reporting configuration is the CSI reporting configuration with the lowest corresponding priority value among the L CSI reporting configurations. When the value v indicated by the RRC signaling is equal to a second value (e.g., 1), the second CSI reporting configuration is the CSI reporting configuration with the highest corresponding priority value among the L CSI reporting configurations.

[0335] Optionally, at least one of the L CSI reporting configurations (or a predefined CSI reporting configuration, or the CSI reporting configuration with the lowest CSI reporting configuration ID, or the CSI reporting configuration with the highest CSI reporting configuration ID, or the CSI reporting configuration with the lowest priority value associated with the CSI reporting configuration, or the CSI reporting configuration with the highest priority value associated with the CSI reporting configuration) includes RRC. Optionally, each of the L CSI reporting configurations includes RRC. RRC can be an RRC parameter or a higher-level parameter. RRC can be an RRC parameter or a higher-level parameter used to indicate a second CSI reporting configuration. Optionally, each of the L CSI reporting configurations includes this parameter. Optionally, the value of this parameter included in each of the L CSI reporting configurations is the same. Optionally, the indication associated with each of the L CSI reporting configurations for the second CSI reporting configuration is the same.

[0336] Optionally, the order of the L CSI reporting configurations can be determined based on the IDs of the L CSI reporting configurations. For example, the order of the L CSI reporting configurations can be determined based on ascending or descending order of their IDs. For example, the first CSI reporting configuration among the L CSI reporting configurations can be the CSI reporting configuration with the smallest / largest corresponding ID value. For example, the last CSI reporting configuration among the L CSI reporting configurations can be the CSI reporting configuration with the largest / smallest corresponding ID value.

[0337] Optionally, the order of the L CSI reporting configurations can be determined based on the priority associated with the L CSI reporting configurations. For example, the order of the L CSI reporting configurations can be determined based on the order of their associated priorities (e.g., from high to low, or from low to high). Alternatively, the order of the L CSI reporting configurations can be determined based on the order of their associated priority values ​​(e.g., ascending or descending). For example, the first CSI reporting configuration in the L CSI reporting configurations could be the CSI reporting configuration with the smallest / largest associated priority value. Similarly, the last CSI reporting configuration in the L CSI reporting configurations could be the CSI reporting configuration with the largest / smallest associated priority value.

[0338] Optionally, the type of the mode associated with the L CSI reporting configurations is Mode B. In Mode B, since the resources used for transmission on the second uplink channel are pre-configured, resource scheduling is relatively inflexible, making it easier for resources associated with CSI reporting in the second uplink channel to conflict with resources associated with CSI reporting in other uplink channels. Defining a priority for CSI reporting in this situation allows the UE and base station to handle the conflict, improving the reliability of the communication system. Optionally, the type of the mode associated with the L CSI reporting configurations is Mode B. In Mode A, although the resources used for transmission on the second uplink channel are dynamically scheduled and resource scheduling is relatively flexible, conflicts may still occur between resources associated with CSI reporting in the second uplink channel and resources associated with CSI reporting in other uplink channels. Similar to Mode B, defining a priority for CSI reporting in this situation allows the UE and base station to handle the conflict, improving the reliability of the communication system.

[0339] The above method ensures that, when L>1, the UE and the base station have the same understanding of the priority of CSI reporting, avoiding the base station demodulating / receiving CSI reports based on incorrect priorities, thereby improving the reliability of the communication system.

[0340] Optionally, the second uplink channel may also carry other CSI reports. Optionally, other CSI reports may include at least one of the following: 1) CSI reports not determined based on the first CSI report configuration; 2) CSI reports not associated with the first CSI report configuration; 3) CSI reports when L=1. Optionally, other CSI reports are associated with the value of the first priority. Optionally, the value of the first priority is less than the maximum value among the priority values ​​associated with the L CSI report configurations, and / or, the value of the first priority is greater than the minimum value among the priority values ​​associated with the L CSI report configurations. Optionally, when the value of the first priority is less than the maximum value among the priority values ​​associated with the L CSI report configurations, and / or, the value of the first priority is greater than the minimum value among the priority values ​​associated with the L CSI report configurations, the UE determines the priority value of the CSI report determined based on the first uplink channel based on the method described above. For example, when L=3, the priority values ​​corresponding to the L CSI reporting configurations are 5, 7, and 8, respectively, and the priority value corresponding to the other CSI reporting is 6. In this case, the UE determines the priority value of the CSI reporting based on the first uplink channel according to the method described above.

[0341] Optionally, the second uplink channel may overlap with the third uplink channel. Optionally, the CSI reporting carried by the third channel is associated with a second priority value. Optionally, the second priority value is less than the maximum value among the priority values ​​associated with the L CSI reporting configurations, and / or the second priority value is greater than the minimum value among the priority values ​​associated with the L CSI reporting configurations. Optionally, when the second priority value is less than the maximum value among the priority values ​​associated with the L CSI reporting configurations, and / or the second priority value is greater than the minimum value among the priority values ​​associated with the L CSI reporting configurations, the UE determines the priority value of the CSI reporting determined based on the first uplink channel based on the method described above. For example, when L=3, the priority values ​​corresponding to the L CSI reporting configurations are 3, 7, and 8, respectively, and the priority value corresponding to the CSI reporting carried by the third uplink channel is 6. In this case, the UE determines the priority value of the CSI reporting determined based on the first uplink channel based on the method described above. The above methods can clearly define the conditions / restrictions for using priority determination methods, avoiding the use of corresponding methods by UE / base station under incorrect conditions / restrictions, and improving the reliability of communication system.

[0342] Optionally, the method described above for determining the priority of CSI reporting associations when L>1 can be enabled / disabled by the base station indication. For example, when the method is enabled, the above method is used. For example, when the method is disabled, the priority of CSI reporting associations is determined based on the first CSI reporting configuration. Optionally, enabling or disabling the method can be indicated by parameters in at least one of the L CSI reporting configurations. Optionally, enabling or disabling the method can be indicated by parameters in each of the L CSI reporting configurations. Optionally, the parameters in each CSI reporting configuration are indicated identically.

[0343] Optionally, when L>1, the second uplink channel used to carry CSI reporting does not overlap with other uplink channels carrying CSI reporting (different from the second uplink channel). Optionally, when L>1, the UE does not expect the second uplink channel used to carry CSI reporting to overlap with other uplink channels carrying CSI reporting. Optionally, when L>1, the UE expects the second uplink channel used to carry CSI reporting not to overlap with other uplink channels carrying CSI reporting. Optionally, the other uplink channels can be PUSCH / PUCCH. Optionally, the CSI reporting carried by the other uplink channels can be semi-persistent CSI reporting. This method can avoid the situation where the priority between CSI reporting in the second uplink channel and CSI reporting in other uplink channels is unclear when L>1 through scheduling constraints, avoiding the UE / base station using priorities or operating based on incorrect priorities, and improving the reliability of the communication system.

[0344] The following describes the situation where the second uplink channel used to carry CSI reporting overlaps with other uplink channels used to carry CSI reporting.

[0345] Optionally, when L>1, the second uplink channel used to carry CSI reporting can overlap with other uplink channels carrying CSI reporting. Optionally, the priority of CSI reporting carried by other uplink channels is different from one of the priorities associated with the L CSI reporting configurations (e.g., any priority, or the highest priority, or the lowest priority, or each priority). Optionally, the priority of CSI reporting carried by other uplink channels is greater than one of the priorities associated with the L CSI reporting configurations (e.g., any priority, or the highest priority, or the lowest priority, or each priority). Optionally, the priority of CSI reporting carried by other uplink channels is less than one of the priorities associated with the L CSI reporting configurations (e.g., any priority, or the highest priority, or the lowest priority, or each priority). Optionally, the UE expects the priority of CSI reporting carried by other uplink channels to be greater than one of the priorities associated with the L CSI reporting configurations (e.g., any priority, or the highest priority, or the lowest priority). Optionally, the UE expects the priority of CSI reports carried by other uplink channels to be lower than the priority of one of the L CSI reporting configurations (e.g., any priority, the highest priority, or the lowest priority). Optionally, the other uplink channel can be PUSCH / PUCCH. Optionally, the CSI reports carried by other uplink channels can be semi-persistent CSI reports. Optionally, when the CSI reports carried by other uplink channels are semi-persistent CSI reports on PUSCH / PUCCH, the ID of the CSI reporting configuration corresponding to the CSI reports carried by other uplink channels is lower than the ID of one of the L CSI reporting configurations (e.g., the ID of any CSI reporting configuration, the ID of the CSI reporting configuration with the highest value, or the ID of the CSI reporting configuration with the lowest value). Optionally, when CSI reports carried by other uplink channels are semi-persistent CSI reports on PUSCH / PUCCH, the ID of the CSI report configuration corresponding to the CSI report carried by other uplink channels is greater than the ID of one of the L CSI report configurations (e.g., the ID of any CSI report configuration, or the ID of the CSI report configuration with the highest value, or the ID of the CSI report configuration with the lowest value). This method can avoid the situation where the priority between CSI reports in the second uplink channel and CSI reports in other uplink channels is unclear when L>1, by scheduling constraints when the uplink channels carrying CSI reports overlap. This avoids the UE / base station operating based on incorrect priorities and improves the reliability of the communication system.

[0346] Optionally, overlap can refer to time-domain overlap or frequency-domain overlap. Optionally, overlap can refer to overlap of time-domain cells containing the uplink channel. Optionally, overlap can refer to overlap of at least one time-domain cell containing the uplink channel. Optionally, overlap can refer to at least one identical time-domain cell containing the uplink channel.

[0347] The following discusses the method for determining the priority of CSI reported configuration associations. The priority of a CSI reported configuration association can be: the priority value of the CSI reported configuration association itself, or the priority value of the CSI reported configuration corresponding to / associated with it. Alternatively, the priority of a CSI reported configuration association can be: the priority value determined by the ID of the CSI reported configuration.

[0348] Optionally, the priority associated with the CSI reporting configuration (e.g., a first CSI reporting configuration, and / or a second CSI reporting configuration) is used for at least one of the following: multiplexing of CSI reports (e.g., multiplexing among multiple CSI reports); discarding of CSI reports (e.g., determining whether to discard a CSI report); sending of CSI reports (e.g., determining whether to send a CSI report); the order of information bits in the CSI report (e.g., the order of information bits carried by multiple CSI reports; e.g., which CSI report carries information bits first, and which CSI report carries information bits last). The order of information bits in the CSI report can be: the order of the information bits associated with / corresponding to the CSI report in the UCI carried by the second uplink channel. The above method can limit the purpose of using the priority. In these purposes, the base station needs to receive / demodulate CSI reports based on the priority associated with the CSI reports. Limiting the purpose of use can clarify the use scenario of the priority determination method, avoid the UE / base station using the corresponding method in the wrong scenario, and improve the reliability of the communication system.

[0349] In this document, two CSI reports are considered to collide if the time-domain resources of the physical channels scheduled to carry the CSI reports overlap in at least one OFDM symbol and are transmitted on the same carrier. Here, the carrier can be the serving cell. Optionally, when the UE is instructed (or configured) to send two conflicting CSI reports, the UE sends the CSI report with higher priority, and / or the UE does not send the CSI report with lower priority. For example, when a UE is instructed (or configured) to send two conflicting CSI reports, and the time-domain behaviors corresponding to these two CSI reports are different, the UE sends the higher-priority CSI report, and / or the UE does not send the lower-priority CSI report. For example, when a UE is instructed (or configured) to send two conflicting CSI reports, and the time-domain behaviors corresponding to these two CSI reports are the same, the two CSI reports are reused, or at least one of the two CSI reports is discarded. Different time-domain behaviors corresponding to the two CSI reports can be: the y values ​​corresponding to the two CSI reports are different (except when the y values ​​of the two CSI reports are 2 and 3 respectively). Optionally, the same time-domain behaviors corresponding to the two CSI reports can be: the y values ​​corresponding to the two CSI reports are the same (including the cases where the y values ​​of the two CSI reports are 2 and 3 respectively). See below for a description of y.

[0350] Optionally, if the priority value associated with one CSI report is lower than the priority value associated with another CSI report, then the priority of the first CSI report can be considered higher than that of the second CSI report. For example, when the priority value associated with a CSI report is 0, the CSI report has the highest priority.

[0351] Optionally, the priority value of the CSI reporting configuration association (or the priority value of the CSI reporting configuration corresponding to the CSI reporting association) can be an integer greater than or equal to 0. Optionally, the priority value of the CSI reporting configuration association (or the priority value of the CSI reporting configuration corresponding to the CSI reporting association) can be determined based on at least one of the following: the mode (type) of the CSI reporting configuration association; the reporting content of the CSI reporting configuration association; the serving cell of the CSI reporting configuration association; the ID of the CSI reporting configuration. Optionally, the priority value of the CSI reporting configuration association is a function of at least one of the following: y; k; c; s. Optionally, y is used to indicate / represent / correspond to the temporal behavior of the CSI reporting configuration association, or y is used to indicate / represent / correspond to the mode (type) of the CSI reporting configuration association. Optionally, k is used to indicate / represent / correspond to the reporting content of the CSI reporting configuration association. In this document, "the reported content associated with CSI reporting configuration" can be used interchangeably with "the content of CSI reporting associated with CSI reporting configuration" or "the content in the CSI report associated with CSI reporting configuration". See above for a description of the reported content associated with CSI reporting configuration. Optionally, 'c' indicates / represents / corresponds to the serving cell associated with the CSI reporting configuration. Optionally, 's' indicates / represents / corresponds to the ID of the CSI reporting configuration. The priority value Pri of the CSI reporting configuration association... iCSI (y,k,c,s) can be determined / calculated using the following formula 1. iCSI (y,k,c,s)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s (Formula 1).

[0352] N cells It is the value of the high-level parameter (N) cells The value of the higher-layer parameter is used to represent / indicate the maximum number of serving cells, such as maxNrofServingCells. Optionally, this higher-layer parameter can be a UE capability indicator.

[0353] M s It is the value of the high-level parameter (M) s(is the value of the higher layer parameter). Optionally, this higher layer parameter can be `maxNrofCSI-ReportConfigurations`. Optionally, this higher layer parameter can be the maximum number used to represent / indicate the CSI reporting configuration. Optionally, this higher layer parameter can be a UE capability indicator.

[0354] Optionally, the value of y can indicate / represent / correspond to the mode associated with the CSI reporting configuration. Optionally, when the CSI reporting configuration is used for CSI reporting initiated by the UE, the value of y can indicate / represent / correspond to the mode associated with the CSI reporting configuration. Optionally, mode A can correspond to a first value, and mode B can correspond to a second value. Optionally, the first value and the second value are different. Optionally, when the CSI reporting configuration is associated with mode A, y equals the first value. Optionally, when the CSI reporting configuration is associated with mode B, y equals the second value. For example, the value of y can be one of 0, 1, 2, 3, 4, 5, 6, 7, 8. For example, the first value can be 0. For example, the second value can be 1. Optionally, this method can be used to determine the priority of one CSI reporting configuration association among L CSI reporting configurations. Optionally, this method can be used to determine the priority of the first CSI reporting configuration association. Optionally, this method can be used to determine the priority of the second CSI reporting configuration association.

[0355] Optionally, the value of y can indicate / represent / correspond to the temporal behavior associated with the CSI reporting configuration. Optionally, when the CSI reporting configuration is not used for UE-initiated CSI reporting, the value of y can indicate / represent / correspond to the temporal behavior associated with the CSI reporting configuration. For example, when the CSI reporting configuration corresponds to a non-periodic CSI reporting, y = 0. Optionally, non-periodic CSI reporting can be on the PUSCH. For example, when the CSI reporting configuration corresponds to a semi-persistent CSI reporting carried by the PUSCH, y = 1. For example, when the CSI reporting configuration corresponds to a semi-persistent CSI reporting carried by the PUCCH, y = 2. For example, when the CSI reporting configuration corresponds to periodic CSI reporting, y = 3. Optionally, periodic CSI reporting can be on the PUCCH.

[0356] Optionally, the value of k is used to indicate / represent / correspond to the reporting content associated with the CSI reporting configuration. Optionally, the value of k can be used to indicate / represent / correspond to the content in the CSI report corresponding to the CSI reporting configuration. For example, for CSI reports carrying L1-RSRP or L1-SINR, k = 0. For example, for CSI reports not carrying L1-RSRP or L1-SINR, k = 1. Optionally, this method can be used to determine the priority of one of the L CSI reporting configurations associated with. Optionally, this method can be used to determine the priority of the first CSI reporting configuration association. Optionally, this method can be used to determine the priority of the second CSI reporting configuration association. For example, the value of k is 0 for the association of L CSI reporting configurations (and / or, the first CSI reporting configuration, and / or, the second CSI reporting configuration). This is because the CSI reporting content associated with the L CSI reporting configurations (and / or, the first CSI reporting configuration, and / or, the second CSI reporting configuration) includes L1-RSRP.

[0357] Optionally, 'c' indicates / represents / corresponds to the ID of the serving cell associated with the CSI reporting configuration. Optionally, the serving cell associated with the CSI reporting configuration includes at least one of the following: 1) the serving cell where the CSI reporting configuration is located; 2) the serving cells where L CSI reporting configurations are located (in this case, the L CSI reporting configurations are located in the same serving cell). Optionally, this method can be used to determine the priority of one of the L CSI reporting configurations associated with a CSI reporting configuration. Optionally, this method can be used to determine the priority of a first CSI reporting configuration association. Optionally, this method can be used to determine the priority of a second CSI reporting configuration association. Optionally, the priority of the second CSI reporting configuration association is determined based on at least one of the following: the serving cell where the second CSI reporting configuration is located, and / or, the serving cell where the first CSI reporting configuration is located, and / or, the serving cells where the L CSI reporting configurations are located. For example, the c associated with the second CSI reported configuration is the ID of the serving cell where the second CSI reported configuration is located; or, the c associated with the second CSI reported configuration is the ID of the serving cell where the first CSI reported configuration is located; or, the c associated with the second CSI reported configuration is the ID of the serving cell where L CSI reported configurations are located.

[0358] Optionally, 's' is used to indicate / represent / correspond to the ID of the CSI reporting configuration. Optionally, the priority associated with a CSI reporting configuration is determined based on the ID of that CSI reporting configuration. For example, 's' equals the value of the ID of the CSI reporting configuration. For example, the priority associated with a first CSI reporting configuration is determined based on the ID of the first CSI reporting configuration. For example, 's' equals the value of the ID of the first CSI reporting configuration. For example, the priority associated with a second CSI reporting configuration is determined based on the ID of the second CSI reporting configuration. For example, 's' equals the value of the ID of the second CSI reporting configuration.
