Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, and more particularly, to a method and device for receiving and transmitting information. BACKGROUND

[0002] To meet the demand for wireless data traffic "off the hook" since deployment of 4G communication systems, efforts have been made to develop an improved 5G or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called a "beyond 4G network" or a "post LTE system."

[0003] The 5G communication system is implemented in terahertz bands (mmWave bands), e.g., 60 GHz bands, to be able to handle a higher data rate than the 4G communication system. To decrease a propagation loss of radio waves and increase a transmission distance, the beamforming, massive multiple-input multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, an analog beam forming, large scale antenna techniques are discussed for use in the 5G communication system.

[0004] In addition, in the 5G communication system, development for system network improvement is under way based on advanced small cells, cloud radio access networks (RANs), ultra-dense networks, a technology for coordination between cells, cooperative multi-point (CoMP), reception-end interference cancellation, and the like.

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

[0006] TECHNICAL PROBLEM

[0007] In order to enhance the scheduling efficiency of the wireless communication system, the base station needs to acquire the channel state information (CSI) so as to schedule correspondingly according to the CSI fed back by the terminal device. However, how to further enhance the performance related to the CSI reporting is a problem to be solved.

[0008] One aspect of this disclosure provides a method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving a channel state information (CSI) reporting configuration; determining the priority of the CSI reporting based on the identifier of the serving cell where a first uplink channel associated with the CSI reporting configuration is located and / or the resource type of the first uplink channel; transmitting the first uplink channel, wherein the first uplink channel is used to notify a second uplink channel carrying a CSI report associated with the CSI reporting configuration, or the first uplink channel is used to request resources of the second uplink channel carrying a CSI report associated with the CSI reporting configuration; and transmitting the CSI report on the second uplink channel.

[0009] In one example, the priority of the CSI reporting is determined based on the minimum value of the identifier of the serving cell where the first uplink channel is located and the identifier of the serving cell where the second uplink channel is located; or, when at least one of the first uplink channel and the second uplink channel is a PUCCH, the priority of the CSI reporting is determined based on a first value; otherwise, the priority of the CSI reporting is determined based on a second value that is different from the first value.

[0010] In one example, the CSI reporting configuration includes a parameter indicating the mode associated with the CSI reporting configuration; when the parameter indicates mode one, the first uplink channel is used to request resources from a second uplink channel carrying CSI reports associated with the CSI reporting configuration, and the priority of the CSI reports is determined based on a third value; and when the parameter indicates mode two, the first uplink channel is used to notify the second uplink channel carrying CSI reports associated with the CSI reporting configuration, and the priority of the CSI reports is determined based on a fourth value different from the third value.

[0011] In one example, the priority of the CSI report is further determined based on at least one of the following: the content of the CSI report; the triggering method of the CSI report; the serving cell associated with the CSI report; the identifier ID configured for the CSI report; the serving cell associated with the CSI report configuration; and the mode associated with the CSI report.

[0012] In one example, the method further includes: receiving an indicated Transmission Configuration Indication (TCI) state, wherein the CSI reporting configuration is associated with a first resource set including K1 reference signal resources for channel measurement, wherein K1 ≥ 1; the first uplink channel is triggered based on the K reference signal resources included in the first resource set and the reference signal resources associated with the indicated TCI state, wherein K ≤ K1; the CSI reporting configuration is associated with a second resource set including K2 reference signal resources for interference measurement, wherein K2 ≥ 1; and the first K1 resources of the K1 reference signal resources and the K2 reference signal resources are associated one-to-one; and the reference signal resources associated with the indicated TCI state are associated with the last reference signal resource of the K2 reference signal resources.

[0013] In one example, the quasi-co-address parameters of the last reference signal resource are determined based on the indicated TCI state.

[0014] In one example, the reference signal resources associated with the indicated TCI state are determined based on the reference signal resources in the cell and / or bandwidth portion (BWP) where the K reference signal resources are located.

[0015] In one example, the CSI reporting configuration is associated with a first parameter and a second parameter, the first parameter being used to indicate the number N of the reported measured reference signal resources, N≥1, the second parameter being used to indicate whether to report the reference signal resources associated with the indicated TCI state, and the method further includes: determining whether to use reporting based on differential layer 1 quantity based on the first parameter and / or the second parameter.

[0016] In one example, determining whether to use differential layer 1 reporting based on the first parameter and / or the second parameter includes: using differential layer 1 reporting if the second parameter indicates that the reference signal resource associated with the indicated TCI state should be reported; or using differential layer 1 reporting if the second parameter indicates that the reference signal resource associated with the indicated TCI state should not be reported, and the first parameter indicates that N is greater than 1; or not using differential layer 1 reporting if the second parameter indicates that the reference signal resource associated with the indicated TCI state should not be reported, and the first parameter indicates that N is equal to 1.

[0017] In one example, if the reference signal resource associated with the indicated TCI state is the same as one of the K reference signal resources included in the first resource set, then the information related to the reference signal resource included in the CSI report is determined based on the reference signal resources in the first resource set that are different from the reference signal resources; and / or, the size of the CSI field corresponding to the information related to the reference signal resource associated with the indicated TCI state included in the CSI report is determined based on K-1.

[0018] In one example, if the second parameter indicates the reference signal resource associated with the indicated TCI state to be reported, and the reference signal resource associated with the indicated TCI state is the same as one of the K reference signal resources associated with the first resource set, then the CSI report does not include information related to the reference signal resource associated with the indicated TCI state.

[0019] In one example, the CSI report includes a first indicator that indicates the reference signal resource associated with the value of the largest measured Layer 1 quantity in the CSI report, which includes one of the following: the reference signal resource associated with the indicated TCI state; or one of the N reported measured reference signal resources.

[0020] In one example, the transmission of the first uplink channel is determined based on at least one of the following: an update of the indicated TCI state, an update of the K reference signal resources associated with the first resource set, a reception of a transmission opportunity for the K reference signal resources associated with the first resource set, a reception of a transmission opportunity for the reference signal resources associated with the indicated TCI state, and a reference time domain unit associated with the first uplink channel.

[0021] In one example, the transmission of the CSI report is determined based on at least one of the following: the update of the indicated TCI state, the update of the K reference signal resources associated with the first resource set, the transmission of the first uplink channel, the reception of the transmission opportunity of the K reference signal resources associated with the first resource set, the reception of the transmission opportunity of the reference signal resources associated with the indicated TCI state, the reference time domain unit associated with the first uplink channel, and the CSI reference resources associated with the CSI report.

[0022] In one example, the transmission opportunity of the reference signal resource associated with the indicated TCI state is during the time when the indicated TCI state is applied.

[0023] Another 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, wherein each of the L CSI reporting configurations is associated with a first uplink channel, wherein each first uplink channel is used to notify a second uplink channel carrying a corresponding CSI reporting configuration associated with a CSI report, or to request resources of the second uplink channel carrying a corresponding CSI reporting configuration associated with a CSI report, wherein L>1; and if a conflict occurs among the L first uplink channels associated with the L CSI reporting configurations, selecting N first uplink channels from the L first uplink channels for transmission based on the priority of the CSI reports associated with the L CSI reporting configurations, wherein 1≤N≤L.

[0024] In one example, a conflict between the L first uplink channels associated with the L CSI reporting configurations includes at least one of the following: the first uplink channels associated with each of the L CSI reporting configurations are transmitted in the same time domain unit; the resources of the L first uplink channels associated with the L CSI reporting configurations overlap; and the resources of the first uplink channels associated with each of the L CSI reporting configurations are the same.

[0025] In one example, the N first uplink channels include the first uplink channels associated with the N CSI reporting configurations with the highest CSI reporting priority among the L CSI reporting configurations.

[0026] In one example, the method further includes: sending the N first uplink channels associated with a second uplink channel.

[0028] In one example, the priority of the CSI reporting is determined based on the minimum value of the identifier of the serving cell where the first uplink channel is located and the identifier of the serving cell where the second uplink channel is located; or, when at least one of the first uplink channel and the second uplink channel is a PUCCH, the priority of the CSI reporting is determined based on a first value; otherwise, the priority of the CSI reporting is determined based on a second value that is different from the first value.

[0029] In one example, the CSI reporting configuration includes a parameter indicating the mode associated with the CSI reporting configuration; when the parameter indicates mode one, the first uplink channel is used to request resources from a second uplink channel carrying CSI reports associated with the CSI reporting configuration, and the priority of the CSI reports is determined based on a third value; and when the parameter indicates mode two, the first uplink channel is used to notify the second uplink channel carrying CSI reports associated with the CSI reporting configuration, and the priority of the CSI reports is determined based on a fourth value different from the third value.

[0032] In one example, the quasi-co-address parameters of the last reference signal resource are determined based on the indicated TCI state.

[0033] In one example, the reference signal resources associated with the indicated TCI state are determined based on the reference signal resources in the cell and / or bandwidth portion (BWP) where the K reference signal resources are located.

[0034] In one example, the CSI reporting configuration is associated with a first parameter and a second parameter, the first parameter being used to indicate the number N of the measured reference signal resources to be reported, N≥1, the second parameter being used to indicate whether to report the reference signal resources associated with the indicated TCI status, and the first parameter and / or the second parameter being used to determine whether to use reporting based on differential layer 1 quantity.

[0035] In one example, if the second parameter indicates that the reference signal resource associated with the indicated TCI state should be reported, reporting based on differential layer 1 quantity is used; or, if the second parameter indicates that the reference signal resource associated with the indicated TCI state should not be reported, and the first parameter indicates that N is greater than 1, reporting based on differential layer 1 quantity is used; or, if the second parameter indicates that the reference signal resource associated with the indicated TCI state should not be reported, and the first parameter indicates that N is equal to 1, reporting based on differential layer 1 quantity is not used.

[0036] In one example, if the reference signal resource associated with the indicated TCI state is the same as one of the K reference signal resources included in the first resource set, then the information related to the reference signal resource included in the CSI report is determined based on the reference signal resources in the first resource set that are different from the reference signal resources; and / or, the size of the CSI field corresponding to the information related to the reference signal resource associated with the indicated TCI state included in the CSI report is determined based on K-1.

[0037] In one example, if the second parameter indicates the reference signal resource associated with the indicated TCI state to be reported, and the reference signal resource associated with the indicated TCI state is the same as one of the K reference signal resources associated with the first resource set, then the CSI report does not include information related to the reference signal resource associated with the indicated TCI state.

[0038] In one example, the CSI report includes a first indicator that indicates the reference signal resource associated with the value of the largest measured Layer 1 quantity in the CSI report, which includes one of the following: the reference signal resource associated with the indicated TCI state; or one of the N reported measured reference signal resources.

[0039] In one example, the transmission of the first uplink channel is determined based on at least one of the following: an update of the indicated TCI state, an update of the K reference signal resources associated with the first resource set, a reception of a transmission opportunity for the K reference signal resources associated with the first resource set, a reception of a transmission opportunity for the reference signal resources associated with the indicated TCI state, and a reference time domain unit associated with the first uplink channel.

[0067] 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.

[0068] 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).

[0069] 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).

[0070] 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.

[0071] 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.

[0072] 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.

[0073] althoughFigure 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).

[0074] 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.

[0075] 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.

[0076] 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.

[0077] The RF signal transmitted from gNB 102 reaches UE 116 after passing through the wireless channel, and the 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.

[0078] 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.

[0079] 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.

[0080] 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.).

[0081] 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.

[0084] 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.

[0085] 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.

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.

[0092] 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.

[0093] 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.

[0094] The controller / processor 378 may include one or more processors or other processing devices that control the overall operation of the gNB 102.

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 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.

[0096] 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.

[0097] 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.

[0098] 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.

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).

[0181] The above method clarifies the configuration restrictions on reference signal resources, enabling the UE and the base station to have the same understanding of how to configure reference signal resources, thereby improving the reliability of the communication system.

[0182] Optionally, the UE may determine the reference signal resource associated with the TCI state based on a first resource set (or, resources associated with the first resource set, or, K resources associated with the first resource set).

[0201] Step 1: Optionally, the UE may transmit a first uplink channel. Optionally, the first uplink channel may indicate / notify a second uplink channel (e.g., a second uplink channel carrying CSI reporting).

Optionally, the time slot offset between the second uplink channel and the first uplink channel is predefined, or based on base station indication, or based on UE capabilities. For example, this time slot offset is configured by the CSI reporting configuration. Optionally, the cell where the second uplink channel resides is determined based on the first uplink channel.

[0203] The following discusses how the UE determines whether to use Mode 1 or Mode 2 for CSI reporting. Optionally, the UE can determine whether to use Mode 1 or Mode 2 based on base station indication. For example, the CSI reporting configuration indicates Mode 1 or Mode 2. For example, the CSI reporting configuration includes a mode parameter, which is used to indicate Mode 1 or Mode 2. Optionally, the parameter used to indicate Mode 1 or Mode 2 can also be referred to as information used to indicate Mode 1 or Mode 2. Optionally, the UE can use Mode 1 or Mode 2 based on UE capabilities. For example, the UE reports a UE capability parameter, where the parameter indicates Mode 1 or Mode 2.

Optionally, when CSI reports configuration association / indication mode two, the first uplink channel of CSI reporting configuration association is used to indicate / notify the second uplink channel (e.g., the second uplink channel carrying the CSI report).

[0205] The triggering methods for the first uplink channel and / or the second uplink channel (in Mode 1 and / or Mode 2) are discussed below. Optionally, the first uplink channel and / or the second uplink channel may be triggered based on a resource set (e.g., a first resource set and / or a second resource set) and / or an indicated TCI state. Optionally, the first uplink channel and / or the second uplink channel may be triggered based on a reference signal resource associated with the resource set and / or a reference signal resource associated with the indicated TCI state. Optionally, the first uplink channel and / or the second uplink channel may be triggered based on the difference between the measurement of the L1 quantity corresponding to / associated with the reference signal resource in the resource set and / or the measurement of the L1 quantity corresponding to / associated with the reference signal resource associated with the indicated TCI state. Optionally, the first uplink channel is triggered when the difference is greater than or equal to a threshold configured by an RRC. For example, if the threshold is configured to 6 dB, and the L1-RSRP corresponding to CSI-RS#1 in the resource set used for channel measurement is 7 dB higher than the L1-RSRP corresponding to the TCI state-associated / corresponding reference signal, then the first uplink channel and / or the second uplink channel is triggered. Optionally, the UE applies this threshold to the scaled L1 quantity. Optionally, the scaled L1 quantity refers to the L1 quantity obtained by scaling the RS (e.g., CSI-RS) reception power with the corresponding (configured) power offset parameter (e.g., powerControlOffsetSS). Optionally, scaling the received power of the reference signal means subtracting the value corresponding to the power offset parameter from the L1 quantity corresponding to the reference signal. For example, if the threshold configured by RRC is 6dB, and the L1-RSRP corresponding to CSI-RS#1 in the measurement resource set is 4dB higher than the L1-RSRP corresponding to the CSI-RS associated with / corresponding to the TCI state, then the L1-RSRP corresponding to the CSI-RS needs to be scaled according to powerControlOffsetSS (e.g., 3dB). After scaling, the L1-RSRP corresponding to CSI-RS#1 is 7dB higher than the L1-RSRP corresponding to / corresponding to the CSI-RS associated with / corresponding to the TCI state, exceeding the threshold, therefore the first uplink channel and / or the second uplink channel is triggered. This method can clearly define how the UE uses power-related parameters to determine the L1 quantity even when the reference signal (e.g., CSI-RS and SSB) types are different, improving the reliability of the communication system. Optionally, the first uplink channel and / or the second uplink channel are transmitted / triggered when at least one of the following conditions is met:

[0206] ●Condition 1: The difference between the L1 value of at least one reference signal resource in the reference signal resource set (e.g., a first resource set and / or a second resource set) and the L1 value of the reference signal resource associated with the indicated TCI state is greater than or equal to a threshold. For example, the L1 value corresponding to / associated with the opportunity of at least one reference signal resource in the reference signal resource set is greater than or equal to the L1 value corresponding to the opportunity of the reference signal resource associated with the indicated TCI state. Optionally, the opportunity of the reference signal resource can be a transmission opportunity of the reference signal resource.

Within a time window, the number of times that at least one identical reference signal resource among the K reference signal resources associated with the first resource set and the L1 value of the reference signal resource associated with the indicated TCI state is greater than or equal to a threshold is greater than or equal to M.

This method allows a time window to include measurement opportunities for an integer multiple of reference signals, enabling the UE to determine, accordingly, the number of times the L1 quantity associated with K reference signal resources is greater than or equal to the L1 quantity of the reference signal resource associated with the indicated TCI state. This promptly triggers CSI reporting, reporting the switchable beam to the base station, reducing latency and improving the efficiency of the communication system. Optionally, the length of a time window can be determined based on the period of the reference signal resources associated with the first resource set and / or the period of the DRX. For example, the length of a time window can be determined based on the larger / smaller value of the period of the reference signal resources associated with the first resource set and the period of the DRX. Optionally, the length of the time window can be determined based on M resource sets associated with M (M≥1) CSI reporting configurations. Optionally, the M resource sets are associated one-to-one with the M CSI reporting configurations. Optionally, the M resource sets refer to the resource sets (used for channel measurement) associated with each CSI reporting configuration in the M CSI reporting configurations. Optionally, the length of the time window can be determined based on the maximum / minimum period among the periods associated with each of the M resource sets. For example, the length of the time window is equal to the maximum / minimum period among the periods associated with each of the M resource sets. Optionally, the period associated with the resource set refers to the period of the reference signal resources in the resource set. Optionally, the start of the time window is determined based on the K reference signal resources and / or the reference signal resources associated with the indicated TCI state. Optionally, the start of the time window is determined based on the time domain unit where the opportunity of the K reference signal resources is located and / or the time domain unit where the reference signal resources associated with the indicated TCI state are located. Optionally, the time window can start from the first symbol of the earliest one of each transmission occasion of K resources. Optionally, the time window may start from the first symbol of the earliest one of each transmission occasion of K resources and the resource associated with the indicated TCI state.Optionally, the time window may end from the last symbol of the latest one of each transmission occasion of K resources. Optionally, the time window may end from the last symbol of the latest one of each transmission occasion of K resources and the resource associated with the indicated TCI state. Optionally, the starting time domain unit of the time window is determined based on the system frame number (SFN). For example, optionally, the starting timeslot and / or starting symbol of the time window is determined based on SFN#0. For example, the starting timeslot of the time window may be timeslot n+k*P, where timeslot n is the first timeslot of SFN#0. Optionally, k≥0. Optionally, k can be an integer.

[0208] Optionally, P represents the period of a time slot. Optionally, the length of the time window is P time slots. Optionally, the start / end of the time window is no later than the transmission of the first uplink channel. Optionally, the time window ends at the first / last time domain unit of the transmission of the first uplink channel. Optionally, the last time domain unit of the time window is earlier than the first / last time domain unit of the transmission of the first uplink channel. Optionally, the last time domain unit of the time window is one time domain unit preceding the first / last time domain unit of the first uplink channel. Optionally, the time domain offset between the last time domain unit of the time window and the first / last time domain unit of the first uplink channel is greater than or equal to X. Optionally, X ≥ 0. Optionally, X can be configured by the base station or determined based on UE capabilities. For example, if the last symbol of the time window is symbol n, then the first symbol of the first uplink channel is no earlier than symbol n+X. For example, if the last symbol of the time window is symbol n, then the first symbol of the first uplink channel is later than symbol n+X. For example, if the last symbol of the time window is symbol n, then the first symbol of the first uplink channel is no earlier than symbol n+X+1. Alternatively, if the last symbol of the time window is symbol n, then the first symbol of the first uplink channel is later than symbol n+X+1. Optionally, X can be used for evaluation time. Optionally, X can be used to indicate the length of the evaluation time. The above method clarifies the determination of the time window, enabling the UE and base station to have a common understanding of the time window used to trigger the first uplink channel, thus improving the reliability of the communication system. The above method can reserve a time interval between the time window and the first uplink channel so that the UE has sufficient time to process the corresponding measurement results, reducing hardware complexity and improving the performance of the communication system.

[0209] The following discusses the content of CSI reporting (e.g., the content of CSI reporting carried / bearing on the second uplink channel, or the content of CSI reporting initiated by the UE). Optionally, the UE can be configured to report the number (N) of reference signal resources, where N≥1. Optionally, the reference signal resources can be the measured reference signal resources. 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 that the UE supports for reporting, as indicated by the UE's capabilities. Optionally, N_max represents the maximum number of L1 quantities that the UE supports for reporting, as indicated by the UE's capabilities. Optionally, N_max represents the maximum number of L1-RSRPs supported by the UE for non-group-based RSRP reporting, as indicated by the UE's capabilities. For example, N_max is indicated by the parameter maxNumberNonGroupBeamReporting. Optionally, N can be predefined or indicated by the base station. Optionally, the UE may receive a first parameter from the base station, wherein the first parameter is used to indicate / configure N. Optionally, the UE may be indicated by the base station whether to report the reference signal resource associated with the indicated TCI state. Optionally, the UE may receive a second parameter from the base station, wherein the second parameter is used to indicate / configure whether to report the reference signal resource associated with the indicated TCI state. For example, when the second parameter indicates enable (or, the second parameter is configured), the CSI report submitted by the UE includes CSI related to the reference signal resource associated with the indicated TCI state. Optionally, reporting the reference signal resource may be: reporting CSI related to the reference signal resource. For example, when the second parameter indicates disable (or, the second parameter is not configured), the CSI report submitted by the UE does not include CSI related to the reference signal resource associated with the indicated TCI state. Optionally, the first parameter and / or the second parameter are in the CSI reporting configuration. Optionally, reporting the reference signal resource may be: reporting information related to the reference signal resource, or reporting CSI related to the reference signal resource. Optionally, the CSI related to the reference signal resource includes: reference signal resource information and / or L1 quantity. In this document, "reference signal resource information" can be used interchangeably with "information related to the reference signal resource associated with the indicated TCI state." The reference signal resource information can be: CRI and / or SSBRI. In this document, the term "second parameter indication enabled" can be used interchangeably with the terms "second parameter configured," "UE reports the reference signal resource associated with the indicated TCI state," or "the CSI reported by the UE includes the reference signal resource associated with the indicated TCI state."In this document, the term "second parameter indication disabled" can be used interchangeably with the terms "second parameter not configured," "UE does not report reference signal resources associated with the indicated TCI state," "UE does not report reference signal resources associated with the indicated TCI state," or "UE's CSI reporting does not include reference signal resources associated with the indicated TCI state." Optionally, when the second parameter indication is enabled, N ≤ N_max-1. Optionally, when the second parameter indication is disabled, N ≤ N_max. This method clarifies the configuration limitations related to the second parameter for N indicated by the first parameter, avoiding incorrect configuration that prevents the UE from making the corresponding report. Optionally, when the second parameter indication is enabled, the UE reports the reference signal resources associated with the indicated TCI state and / or the reference signal resources associated with the first resource set and / or the reference signal resources associated with the second resource set in one report instance.

[0210] Optionally, the UE determines whether to use differential L1 quantity-based reporting based on the first parameter and / or the second parameter. Optionally, the UE determines whether to use differential L1 quantity-based reporting based on the first parameter and / or the second parameter. Optionally, if the second parameter indicates enable, the UE uses differential L1 quantity-based reporting.

[0211] Optionally, if the second parameter indicates enable and the first parameter indicates N is greater than 1, the UE uses differential L1 quantity reporting. Alternatively, if the second parameter indicates enable and the first parameter indicates N equals 1, the UE uses absolute L1 quantity reporting (or the UE does not use differential L1 quantity reporting). For example, if the second parameter indicates enable and the first parameter indicates N equals 1, the L1 quantity (or the value of the L1 quantity) reported by the UE is a predefined number of bits. For example, the value of the L1 quantity is a 5-bit or 7-bit value. Optionally, the range of the L1 quantity can be from -140dBm to -44dBm. Optionally, the quantization step size of the L1 quantity can be 1dB. The above method clarifies the relationship between the first parameter and / or the second parameter and whether the UE uses differential reporting, ensuring that the UE and the base station have the same understanding, thus improving the reliability of the communication system.

[0212] Optionally, the UE determines and / or reports CSI based on the CSI reporting configuration. The following discusses a CSI reporting method when the second parameter indication is enabled. Optionally, if the second parameter indication is enabled, the CSI reporting includes N reference signal resource information and N+1 L1-RSRPs.

[0213] ● Optionally, there is a one-to-one correspondence between the N reference signal resource information and the N L1 quantities among the N+1 L1 quantities (e.g., the first N L1 quantities, or the last N L1 quantities). For example, the nth reference signal resource information among the N reference signal resource information corresponds to the nth L1 quantity among the N+1 L1 quantities. For example, the nth L1 quantity among the N+1 L1 quantities is determined based on the reference signal corresponding to the nth reference signal resource information among the N reference signal resource information.

[0214] ● Optionally, one of the N+1 L1 quantities (e.g., a predefined L1 quantity, the last L1 quantity, or the first L1 quantity) corresponds to a reference signal resource associated with the indicated TCI state. For example, the last L1 quantity among the N+1 L1 quantities is determined based on the reference signal resource associated with the indicated TCI state.

Optionally, the largest measured L1 quantity is a predefined one (e.g., the first or the last) of the N L1 quantities (e.g., the first or the last) of the N L1 quantities (e.g., the first or the last). Optionally, the largest measured L1 quantity is a predefined one (e.g., the first or the last) of N+1 L1 quantities.

[0217] ● Optionally, the N reference signal resource information (in the CSI report) is determined based on the reference signal resources in the first resource set associated with the CSI reporting configuration. For example, the N reference signal resource information corresponds to N resources out of the K resources associated with the first resource set. Alternatively, the N reference signal resource information represents N resources out of the K resources. Optionally, the size of the CSI field corresponding to the N reference signal resource information is... Alternatively, log2(K). Optionally, the value of the reference signal resource information is denoted as k (k≥0). Optionally, k corresponds to the (k+1)th resource configured in the first resource set. Optionally, k corresponds to the (k+1)th resource among the K reference signal resources associated with the first resource set.

[0218] Optionally, the mapping order of CSI fields in a CSI report is shown in Table 1. Optionally, the UE can determine the CSI based on Table 1. Optionally, the CSI report includes: CRI / SSBRI#1, CRI / SSBRI#2, ..., CRI / SSBRI#N. Optionally, the CRI / SSBRI-related CSIs are sorted in ascending order based on the CRI / SSBRI numbers. Optionally, the CSI report includes: L1-RSRP#1 and differential L1-RSRP#2, ..., differential L1-RSRP#N. Optionally, L1-RSRP#n corresponds to CRI / SSBRI#n. Optionally, L1-RSRP#1 is the largest measured L1 quantity in the CSI report. Optionally, differential L1-RSRP#X is the L1-RSRP associated with the reference signal resource related to the indicated TCI state.

[0221] Table 1. Mapping order of CSI fields in a CSI report

[0222] The following discusses another method for CSI reporting when the second parameter indication is enabled. Optionally, if the second parameter indication is enabled, the CSI reporting includes N+1 reference signal resource information and N+1 L1 quantities.

[0223] ● Optionally, there is a one-to-one correspondence between the N+1 reference signal resource information and the N+1 L1 quantities. For example, the nth reference signal resource information in the N+1 reference signal resource information corresponds to the nth L1 quantity in the N+1 L1 quantities. For example, the nth L1 quantity in the N+1 L1 quantities is determined based on the reference signal corresponding to the nth reference signal resource information in the N+1 reference signal resource information.

[0224] ● Optionally, one of the N+1 L1 quantities (e.g., a predefined L1 quantity, the last L1 quantity, or the first L1 quantity) is associated with the largest measured L1 quantity. Optionally, the largest measured L1 quantity refers to the largest measured L1 quantity within the same reporting instance.

[0225] ● Optionally, the N+1 reference signal resource information (in CSI reporting) is determined based on the reference signal resources in the first resource set associated with the CSI reporting configuration and the reference signal resources related to the indicated TCI state. Optionally, each reference signal resource information is determined based on the reference signal resources in the resource set for channel measurement associated with the CSI reporting configuration and the reference signal resources related to the indicated TCI state. Optionally, the size of the CSI domain corresponding to the N reference signal resource information is or log2(K+1). Optionally, the value of the reference signal resource information is denoted as k (k≥0). Optionally, k corresponds to the (k+1)-th resource configured in the first resource set. Optionally, when k<K, k corresponds to the (k+1)-th resource among the K reference signal resources associated with the first resource set. When k = K, the reference signal resource information k corresponds to the reference signal resources related to the indicated TCI state.

[0226] Optionally, a predefined code point (e.g., the first code point or the last code point) of the CSI domain corresponding to the reference signal resource information corresponds to the reference signal resources related to the indicated TCI state.

[0227] Optionally, for the mapping order of the CSI domain in a CSI reporting, refer to Table 2. Optionally, the UE can determine the CSI based on Table 2.

Optionally, the size of each CRI / SSBRI domain in CRI / SSBRI#1, CRI / SSBRI#2, ……, CRI / SSBRI#N+1 is

[0228] Table 2. Mapping order of the CSI domain in a CSI reporting

[0229] The above method clarifies how to report CSI when the second parameter is enabled, enabling the UE and the base station to have the same understanding of the reported CSI and improving the reliability of the communication system.

[0230] The reference signal resource associated with the indicated TCI state may be the same as or different from one of K resources (e.g., the K resources associated with the first resource set). When the reference signal resource associated with the indicated TCI state is the same as one of the K resources (e.g., the K resources associated with the first resource set), the UE may repeatedly report the same resource. Methods to avoid the UE reporting duplicate resources are discussed below.

[0231] ● Optionally, if the reference signal resource associated with the indicated TCI state is the same as one of the K resources associated with the first resource set, then the reference signal resource information included in the CSI report is determined based on the resources among the K reference signal resources associated with the first resource set that are different from the reference signal resource associated with the indicated TCI state. For example, if the reference signal resource associated with the indicated TCI state is CSI-RS#1, and the K reference signal resources include CSI-RS#1, CSI-RS#2, and CSI-RS#3, since CSI-RS#1 is both associated with the indicated TCI state and is one of the K resources, then the reported CSI is determined based on CSI-RS#2 and CSI-RS#3. Optionally, the size of the CSI field corresponding to / associated with the reference signal resource information is based on Alternatively, it can be determined by log2(K-1). Optionally, the value of the reference signal resource information is denoted as k (k≥0). Optionally, k≤K-1. Optionally, k corresponds to the (k+1)th resource in the configuration of the K reference signal resources associated with the first resource set that is different from the reference signal resource related to the indicated TCI state.

[0232] ● Optionally, if the reference signal resource associated with the indicated TCI state is the same as one of the K resources associated with the first resource set, then the CSI report does not include the reference signal resource associated with the indicated TCI state. In this document, "the reference signal resource associated with the indicated TCI state is different from all K resources associated with the first resource set," or "the reference signal resource associated with the indicated TCI state is different from any one of the K resources associated with the first resource set," can be referred to as the first condition. In this document, "the reference signal resource associated with the indicated TCI state is the same as one of the K resources associated with the first resource set"

[0233] This can be referred to as the second condition. Optionally, if the second condition is met, and the second parameter indicates enable, the reference signal resources associated with the indicated TCI state are not included in the CSI report. Optionally, when the second condition is met, the differential L1-RSRP in Table 1...

[0234] #X is not reported. Optionally, the UE determines the use of differential L1 quantity based on the indicated TCI state. Optionally, if the second parameter indicates enable, and the first condition is met, the UE uses reporting based on differential L1 quantity. Optionally, if the second parameter indicates enable, and the second condition is met, and the first parameter indicates N is greater than 1, the UE uses reporting based on differential L1 quantity. Optionally, if the second parameter indicates enable, and...

[0235] If the second condition is met, and N, as indicated by the first parameter, is equal to 1, then the UE uses reporting based on absolute L1 quantities (or the UE does not use reporting based on differential L1 quantities).

[0236] The above methods can prevent the UE from repeatedly reporting the same CSI for the same resource, thus improving the efficiency of the communication system.

[0237] Optionally, the CSI report may include an indicator that indicates the reference signal resource associated with the largest L1 quantity of the measurement (in the CSI report). Optionally, the indicator indicates that the reference signal resource associated with the largest L1 quantity of the measurement is one of the following:

[0238] ●Reference signal resources related to the indicated TCI state;

[0239] ● One of the N reported reference signal resources. Optionally, one of the N reported reference signal resources can be the first / last of the N reported reference signal resources.

[0240] Optionally, the size of the CSI field corresponding to this indicator is 1 bit. Optionally, when the indicator indicates 0, the reference signal resource associated with the largest measured L1 quantity is the reference signal resource associated with the indicated TCI state. Optionally, when the indicator indicates 1, the reference signal resource associated with the largest measured L1 quantity is one of the N reported reference signal resources (e.g., the first or the last). Here, the indicator indicating 1 and the indicator indicating 0 are merely exemplary.

[0241] Optionally, the mapping order of CSI fields in a CSI report is shown in Table 3. Optionally, the UE can determine the CSI based on Table 3. Optionally, the CSI report includes: CRI / SSBRI#1, CRI / SSBRI#2, ..., CRI / SSBRI#N. Optionally, the CRI / SSBRI related CSIs are sorted in ascending order of CRI / SSBRI numbers. Optionally, the CSI report includes: L1-RSRP#1 and differential L1-RSRP#2, ..., differential L1-RSRP#N+1. Optionally, when the indicator indicates 0, L1-RSRP#1 corresponds to the reference signal resource related to the indicated TCI state. Differential L1-RSRP#2, ..., differential L1-RSRP#N+1 correspond to the N reported resources. Optionally, (differential) L1-RSRP#n+1 corresponds to CRI / SSBRI#n. Optionally, when the indicator indicates 1, (differential) L1-RSRP#n corresponds to CRI / SSBRI#n. Differential L1-RSRP#N+1 corresponds to the reference signal resource related to the indicated TCI state.

[0243] Table 3. Mapping order of CSI fields in a CSI report

[0244] The above methods enable the UE and the base station to have the same understanding of the largest L1 quantity measured in the CSI report, thereby improving the reliability of the communication system.

[0245] The following discusses the method for determining the priority of CSI reports (e.g., UE-initiated CSI reports). CSI reports can be associated with a priority value. If the priority value associated with a first CSI report is lower than the priority value associated with a second CSI report, then the first CSI report can be considered to have higher priority than the second CSI report (or, the first CSI report can be considered to have a higher priority than the second CSI report). The priority (or priority value) of a CSI report is determined based on at least one of the following:

[0246] ●First uplink channel;

[0247] ●Second uplink channel;

[0248] ●The content reported by CSI;

[0249] ● Triggering method reported by CSI;

[0250] ●CSI reports the associated serving cell;

[0251] ●CSI configuration reporting;

[0252] ●CSI reporting associated modes.

[0253] Optionally, the priority of CSI reporting is determined based on first information associated with the first uplink channel. Optionally, this first information may include: the serving cell (or the ID of the serving cell) where the first uplink channel resides, and / or, the resource type of the first uplink channel. Optionally, determining the priority (or priority value) of CSI reporting based on the first uplink channel means that the priority (or priority value) of CSI reporting is determined based on the cell (or the ID of the cell) associated with / where the first uplink channel resides, and / or based on the resource type of the first uplink channel. Here, the resource type of the first uplink channel can be PUCCH or PUSCH. For example, when the first uplink channel is in different serving cells, the priority (or priority value) of the associated CSI reporting is different. For example, when CSI reporting is performed on resources of different types of first uplink channels, the priority (or priority value) of CSI reporting is different.

[0254] Optionally, the priority of CSI reporting is determined based on second information associated with the second uplink channel. Optionally, this second information may include at least one of the following: the serving cell (or the ID of the serving cell) where the second uplink channel resides; the resource type of the second uplink channel; and whether the second uplink channel is associated with Downlink Control Information (DCI) format. Optionally, determining the priority (or priority value) of CSI reporting based on the second uplink channel means that the priority (or priority value) of CSI reporting is determined based on the cell (or the ID of the cell) to which the second uplink channel is associated / resides, and / or based on the resource type of the second uplink channel, and / or based on whether the second uplink channel is associated with DCI. Here, the resource type of the second uplink channel can be PUCCH or PUSCH. Optionally, if the second uplink channel is triggered / scheduled by DCI, then the second uplink channel is associated with DCI. Optionally, if the second uplink channel is pre-configured or triggered by configuration permission, then the second uplink channel is not associated with DCI. For example, the priority (or priority value) of CSI reporting differs depending on whether it is associated with a DCI or not. Similarly, the priority (or priority value) of associated CSI reporting differs when the second uplink channel is in a different serving cell. Furthermore, the priority (or priority value) of CSI reporting differs when it is reported on resources of different types of second uplink channels.

[0255] Optionally, the priority of CSI reporting is determined based on the identifiers of the serving cell where the first uplink channel resides and the serving cell where the second uplink channel resides. Optionally, the priority of CSI reporting is determined based on the serving cell (identifier) ​​with the smallest / largest identifier value among the serving cells where the first and second uplink channels reside. Optionally, the priority of CSI reporting is determined based on the minimum / maximum value between the identifier value of the serving cell where the first uplink channel resides and the identifier value of the serving cell where the first uplink channel resides. For example, if the first uplink channel is transmitted in serving cell #1 and the second uplink channel is transmitted in serving cell #3, then the corresponding CSI reporting priority is determined based on serving cell #1, which has the smaller identifier. For example, if the first uplink channel is transmitted in serving cell #1 and the second uplink channel is transmitted in serving cell #3, then the corresponding CSI reporting priority is determined based on the minimum value of 1 between 1 and 3. For CSI reports initiated by the UE, the UE can associate with multiple cells (e.g., the serving cell where the first uplink channel is located and the serving cell where the second uplink channel is located). The above method clarifies how the UE determines the priority of CSI reports based on these serving cells when CSI reports are associated with multiple cells, so that the UE and the base station have the same understanding of the priority of CSI reports, thereby improving the reliability of the communication system.

[0256] Optionally, when at least one of the first uplink channel and the second uplink channel is a PUSCH or at least one of the first uplink channel and the second uplink channel is a PUCCH, the priority of CSI reporting is determined based on a first value; otherwise, the priority of CSI reporting is determined based on a second value. Optionally, the first value and the second value are different. For example, the first value is greater than or less than the second value. Optionally, the first value can be an integer. Optionally, the second value can be an integer.

[0257] Optionally, determining the priority (or priority value) of CSI reporting based on the content of the CSI report means that the priority (or priority value) of the CSI report is determined based on the first parameter and / or the second parameter, or based on the value of the first parameter and / or the value of the second parameter. For example, when the quantity N indicated by the first parameter is different, the priority (or priority value) of the associated CSI report is different. For example, the priority (or priority value) of CSI reports that are enabled and those that are disabled, as indicated by the second parameter, is different.

[0258] Optionally, determining the priority (or priority value) of CSI reporting based on the triggering method of CSI reporting means that the priority (or priority value) of CSI reporting is determined based on whether the CSI reporting is triggered by the base station or initiated by the UE. For example, the priority (or priority value) of CSI reporting triggered by the base station is different from that of CSI reporting initiated by the UE.

[0259] Optionally, determining the priority (or priority value) of CSI reporting based on the triggering method of CSI reporting means that the priority (or priority value) of CSI reporting is determined based on whether CSI reporting is triggered by DCI. For example, the priority (or priority value) of CSI reporting triggered by DCI is different from that of CSI reporting not triggered by DCI.

[0260] Optionally, determining the priority (or priority value) of CSI reporting based on the cell associated with the CSI reporting means that the priority (or priority value) of CSI reporting is determined based on the serving cell in which the CSI reporting takes place. For example, when CSI reporting occurs in different serving cells, the priority (or priority value) of CSI reporting will be different.

[0261] Optionally, determining the CSI reporting priority (or priority value) based on the CSI reporting configuration means that the CSI reporting priority (or priority value) is determined based on the cell associated with / where the (corresponding) CSI reporting configuration resides, and / or based on the ID of the CSI reporting configuration. For example, if the CSI reporting configurations are in different serving cells, the CSI reporting priority (or priority value) will be different. For example, if the IDs of the CSI reporting configurations associated with the CSI reporting are different, the CSI reporting priority (or priority value) will be different.

[0262] Optionally, determining the priority (or priority value) of CSI reporting based on the associated mode means that the priority (or priority value) of CSI reporting is determined based on the mode associated with the (corresponding) CSI reporting configuration. For example, if the associated modes of CSI reporting (or CSI reporting configuration) are different (e.g., mode one or mode two), the priority (or priority value) of CSI reporting will be different. For instance, if one CSI report is associated with mode one and another CSI reports with mode two, then the priorities (or priority values) of these two CSI reports will be different.

[0263] Optionally, when the mode parameter indicates mode one (or, when the CSI reporting configuration is associated with mode one), the first uplink channel is used to request resources from the second uplink channel carrying the CSI report (as associated with the CSI reporting configuration), and the priority of the (corresponding) CSI report is determined based on a third value. When the mode parameter indicates mode two (or, when the CSI reporting configuration is associated with mode two), the first uplink channel is used to indicate / notify the second uplink channel (e.g., the second uplink channel carrying the CSI report), and the priority of the (corresponding) CSI report is determined based on a fourth value. Optionally, the third value and the fourth value are different. For example, the third value is greater than or less than the fourth value. Optionally, the third value can be an integer. Optionally, the fourth value can be an integer.

[0264] Since the second uplink channel including CSI reporting in Mode 1 is initiated autonomously by the UE, while the second uplink channel including CSI reporting in Mode 2 is scheduled by the base station, these two modes can have different priorities. This allows for the determination of priority in the event of a conflict between the CSI reporting of the two modes, and in some cases, the conflict can be resolved by the UE discarding the lower-priority CSI reporting, thus improving the reliability of the communication system. Compared to Mode 2, CSI reporting associated with Mode 1 can have a higher priority, allowing the base station to cancel the transmission of CSI reporting associated with Mode 2 by scheduling CSI reporting associated with Mode 1, thereby improving the flexibility of the communication system.

[0265] The method for determining the priority value reported by CSI is discussed below. Optionally, CSI reports the associated / corresponding priority (e.g., priority value, Pri). iCSI The value is determined / calculated using the following formula 1:

[0266] Pri iCSI (y,k,c,s)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s (Formula 1)

[0267] The meanings and / or values ​​of each parameter are as follows:

[0268] ●The values ​​of y are determined as follows:

[0269] ■Optionally, for CSI reporting in Mode 1, y = 0.

[0270] ■Optionally, for CSI reporting carried by PUSCH in Mode 1, y = 0.

[0271] ■Optionally, for CSI reports triggered / configured by the base station, y=0.

[0272] ■Optionally, for CSI reporting triggered by DCI, y = 0.

[0273] ■Optionally, for CSI reports initiated by the UE, y = 0.

[0274] ■Optionally, for CSI reporting in Mode 2, y = 1.

[0275] ■Optionally, for CSI reports initiated by the UE, y=1.

[0276] ■Optionally, for CSI reporting in mode two (UE-initiated), y = 1.

[0277] ■Optionally, for CSI reporting carried by PUSCH in Mode 2, y = 1.

[0278] ■Optionally, for CSI reporting carried by PUCCH in Mode 2, y = 2.

[0279] ■Optionally, y = 0.

[0280] The values ​​of ∈k are taken in the following ways:

[0281] ■ For CSI reports carrying L1-RSRP or L1-SINR, k = 0; for CSI reports not carrying L1-RSRP or L1-SINR, k = 1.

[0282] ∈c refers to the serving cell index.

[0283] ■Optionally, the serving cell refers to the serving cell where the first uplink channel is located. Optionally, the serving cell refers to the serving cell where the second uplink channel is located. Optionally, the serving cell refers to the serving cell where the CSI report is made. Optionally, the serving cell can be the serving cell with the smallest cell identifier value between the serving cell where the first uplink channel is located and the serving cell where the second uplink channel is located. Optionally, c can be equal to / based on the minimum / maximum value between the identifiers of the serving cell where the first uplink channel is located and the identifiers of the second uplink channel. This method clarifies how the priority value of CSI reporting is determined based on the serving cell, enabling the UE and the base station to have the same understanding of these priority values ​​for CSI reporting, thus improving the reliability of the communication system.

[0284] ●N cells This refers to the value of the high-level parameter (N) cells The value of the higher-layer parameter is used to represent the maximum number of serving cells, for example, maxNrofServingCells. Optionally, this higher-layer parameter is related to UE capabilities.

[0285] ●s refers to the report configuration ID parameter (s is the reportConfigID), for example, the corresponding report configuration ID parameter for CSI reporting.

[0286] ●M s This refers to the value of the high-level parameter (M) s The value of the higher-layer parameter is used to represent the maximum number of configurations to be reported, such as maxNrofCSI-ReportConfigurations. Optionally, this higher-layer parameter is related to UE capabilities.

[0287] Optionally, 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, then the two CSI reports are said to collide.

[0288] Optionally, if the values ​​of y reported by the two CSIs are different, then the one with the higher Pri value in the two CSI reports is considered the better. iCSI CSI reports with values ​​(y, k, c, s) are not sent by the UE. Optionally, if two CSI reports have the same value for y, the two CSI reports can be multiplexed, or one of the two CSI reports can be dropped based on a priority value.

[0289] Optionally, CSI reports initiated by the UE have a higher priority than CSI reports triggered / configured by the base station. Optionally, in the case of CSI report collision, or in the case of CSI multiplexing or CSI dropping, a CSI report initiated by the UE has a higher priority than a CSI report(s) triggered / configured by the base station. Optionally, in the case of CSI report collision, or in the case of CSI multiplexing or CSI dropping, a CSI report initiated by the UE has a higher priority than a CSI report triggered / configured by the base station, regardless of the CSI report's priority. iCSI What are the values ​​of (y,k,c,s)? Optionally, the base station-triggered / configured CSI reporting can be / can include: CSI reporting configured for / for Layer 1 / Layer 2 Triggered Mobility (L1 / L2 Triggered Mobility, LTM) (e.g., higher-layer parameter LTM-CSI-ReportConfig). Optionally, the base station-triggered / configured CSI reporting can be / can include CSI reporting configured by higher-layer parameter CSI-ReportConfig. Optionally, the base station-triggered / configured CSI reporting includes CSI reporting configured by higher-layer parameter CSI-ReportConfig and / or higher-layer parameter LTM-CSI-ReportConfig. This method clarifies the UE's handling method for CSI reporting conflicts, ensuring that the UE and base station have the same understanding regarding whether these CSI reports are sent, thus improving the reliability of the communication system.

[0290] The following discusses the transmission conditions for CSI reports (e.g., UE-initiated CSI reports). In some cases, not enough measurements may be received (e.g., measurements of reference signals), and consequently, meaningful reports cannot be generated due to incomplete measurement information. Therefore, uplink transmission may be omitted to conserve uplink transmission resources. The following specifically describes the conditions under which the first uplink channel and / or CSI reports (e.g., CSI reports carried by the second uplink channel) associated with the CSI reporting configuration described in this embodiment (e.g., the CSI reporting configuration for / for UE-initiated CSI reports) should be transmitted or discarded.

Optionally, an update of the indicated TCI state means that the UE receives an indication of the (most recent) indicated TCI state. Optionally, an update of the indicated TCI state means that the indicated TCI state is different from the previously indicated one.

[0329] The above methods clarify the sending conditions for CSI reporting initiated by the UE, enabling the UE and the base station to have a common understanding of the conditions for CSI reporting, thereby improving the reliability of the communication system.

[0330] In this document, the indicated TCI state can be at least one of the following: an indicated TCI state applied by the UE; the most recent indicated TCI state; an indicated TCI state no later than the first uplink channel; or an indicated TCI state no later than the second uplink channel. For example, the indicated TCI state can be: the most recent (UE-applied) indicated TCI state no later than the first uplink channel. For example, the indicated TCI state can be: the most recent (UE-applied) indicated TCI state no later than the second uplink channel.

[0331] The above embodiments provide a configuration method / sending method for UE-initiated CSI reporting, enabling the UE to initiate corresponding CSI reporting for specific link conditions, so that the base station can obtain CSI information in a timely manner for subsequent scheduling, thereby improving the efficiency of the communication system.

[0332] In some cases, the UE receives / detects a DCI that schedules a PUSCH without a TB (Through Base Station). Optionally, the PUSCH carries one or more CSI reports indicated / triggered by the DCI. Optionally, each of the one or more CSI reports can be a UE-initiated CSI report or a base station-triggered CSI report. Optionally, the DCI can indicate / trigger the one or more CSI reports through its "CSI Request" field. Optionally, the UE can determine K2 based on a higher-layer parameter associated with the one or more CSI reports that indicates the time offset. Optionally, K2 represents / indicates the time offset. Optionally, each of the one or more CSI reports is associated with / corresponds to a time offset parameter. Optionally, the time offset parameter is used to indicate / represent / determine the time offset of the PUSCH / PUCCH reporting the CSI. Optionally, the time offset can be a slot offset. Optionally, the time offset parameter can be a list (e.g., reportSlotOffsetList). Optionally, the time offset parameter list may include one or more parameters, each corresponding to a time slot offset. Optionally, the UE determines the time slot for transmitting the PUSCH based on the time slot in which the DCI is received / detected and K2. For example, if the UE detects the DCI in time slot n, then the UE transmits the PUSCH in time slot n+K2. The method for determining K2 is discussed below when one or more CSI reports triggered by the DCI include a UE-initiated CSI report. A description of UE-initiated CSI reports is provided above. Here, the UE-initiated CSI report can be a CSI report in Mode 1.

[0333] ● If the one or more CSI reports include (only) a CSI report initiated by a single UE, then K2 is determined based on the time offset parameters (e.g., a list of time offset parameters) associated with that CSI report. Optionally, the time domain resource assignment field of the DCI can indicate a value m. Optionally, m corresponds to / is associated with / indicates the (m+1)th item in the list of time offset parameters associated with the CSI report. The UE determines the parameter in the (m+1)th item of the list of time offset parameters as the value of K2.

[0334] ●If the one or more CSI reports include N UEI (N UEI If ≥1) UEs initiate CSI reports, then K2 is based on that N UEI The time offset parameter associated with the CSI report initiated by each UE is determined. Optionally, the time domain resource assignment field of the DCI can indicate a value m. Optionally, m corresponds to / associates with / indicates N. UEIThe (m+1)th item in the list of time offset parameters associated with each CSI report initiated by a UE. UEI The maximum / minimum value among the (m+1)th values ​​is taken as the value of K2. Optionally, N UEI A CSI report initiated by a UE can be CSI report #n, n

[0335] =0,1,…,N UEI -1. Optionally, Y represents the time slot offset, and Y n (m+1) represents the (m+1)th item in the slot offset list associated with CSI report #n.

[0336] Since UE-initiated CSI reports usually reflect the need for improvement in the UE's link quality, they are more important than other CSI reports and need to be prioritized. Therefore, the above method can determine K2 by using the time offset associated with the UE-initiated CSI report when multiple CSI reports are triggered, so as to prioritize meeting the latency requirements of the UE-initiated CSI reports and improve the reliability of the communication system.

[0337] Figure 5 A method 500 performed by a user equipment (UE) according to various embodiments of the present disclosure is illustrated. Method 500 includes: at 501, the UE receives L (L>1) Channel State Information (CSI) reporting configurations from a base station, wherein each of the L CSI reporting configurations is associated with a first uplink channel, wherein each first uplink channel is used to notify the base station of a second uplink channel carrying the CSI report associated with the corresponding CSI reporting configuration, or to request resources from the base station to carry the second uplink channel carrying the CSI report associated with the corresponding CSI reporting configuration; at 502, if a conflict occurs among the L first uplink channels associated with the L CSI reporting configurations, the UE selects N (1≤N≤L) first uplink channels from the L first uplink channels for transmission based on the priority of the CSI reports associated with the L CSI reporting configurations. Detailed descriptions of each operation are given below.

[0338] In some cases, the UE receives L (L>1) CSI reporting configurations. Optionally, each of the L CSI reporting configurations (or at least one CSI reporting configuration) is associated with a CSI report initiated by the UE. A description of the UE-initiated CSI report is provided above. Each of the L CSI reporting configurations (or at least one CSI reporting configuration) is associated with a first uplink channel. Optionally, the first uplink channel is used to notify a second uplink channel carrying the CSI report; or, the first uplink channel is used to request resources from the second uplink channel carrying the CSI report.

[0339] Optionally, if a collision occurs between L CSI reports associated with (L) first uplink channels, the UE transmits N (non-colliding) first uplink channels from the collapsing first uplink channels. Optionally, N ≤ L and / or N ≤ N_max. Optionally, the N first uplink channels are determined based on UE selection, or are selected by the UE. Optionally, N is configured by the base station, or N is indicated by UE capabilities. Optionally, N is predefined, for example, 1 or 2. Optionally, N_max can be indicated / configured by the base station, or determined based on UE capabilities, or predefined. Optionally, N_max can be one of 1, 2, 3, or 4.

[0340] Optionally, if a conflict occurs between L CSI reports associated with (L) first uplink channels, the UE resolves the conflict based on the priority of the L CSI reports associated with the configuration. Optionally, if a conflict occurs between L CSI reports associated with (L) first uplink channels, the UE resolves the conflict based on the resource ID (or the associated scheduling request configuration ID or the associated cell ID) associated with the (L) first uplink channels. Optionally, if a conflict occurs between L CSI reports associated with (at least two) first uplink channels, the UE resolves the conflict based on the priority of the CSI reports associated with the conflicting first uplink channels. Optionally, if a conflict occurs between L CSI reports associated with (at least two) first uplink channels, the UE resolves the conflict based on the resource ID (or the associated scheduling request configuration ID or the associated cell ID) associated with the conflicting first uplink channels.

[0341] In this paper, a conflict can be defined as resource overlap or identical resources. For example, a conflict can refer to resource overlap / identicality between two or more uplink channels. Here, resource overlap can be temporal resource overlap. For example, a conflict between two or more first uplink channels means that the resources of the two or more uplink channels overlap / identicality. Alternatively, a conflict can refer to resources being in the same temporal unit. For example, a conflict between two or more first uplink channels means that the resources of the two or more uplink channels are in the same temporal unit.

[0342] Optionally, if the UE will transmit the first uplink channel associated with each of the L CSI reporting configurations (or at least one CSI reporting configuration) in the same time domain unit, the UE determines / selects the first uplink channel associated with N (1≤N≤L) CSI reporting configurations in the L CSI reporting configurations for transmission, and / or transmits the second uplink channel associated with the first uplink channel associated with the N CSI reporting configurations.

[0343] Optionally, if the UE is to transmit the first uplink channels associated with each CSI reporting configuration among the L CSI reporting configurations in the same time domain unit, and the resources associated with the L first uplink channels are the same, the UE determines / selects the second uplink channels (or, CSI reports) associated with N (1 ≤ N ≤ L) CSI reporting configurations among the L CSI reporting configurations for transmission.

[0344] Optionally, if the UE is to transmit the first uplink channels associated with each (or at least one) CSI reporting configuration among the L CSI reporting configurations in the same time domain unit, (and the resources of the L first uplink channels overlap / are the same,) the UE transmits the first uplink channels associated with N (1 ≤ N ≤ L) CSI reporting configurations among the L CSI reporting configurations based on the priorities of the CSI reports associated with the L CSI reporting configurations, and / or the second uplink channels associated with the first uplink channels associated with the N CSI reports. When N = 1, the CSI reporting configuration refers to: the CSI reporting configuration with the highest / lowest priority among the CSI reports associated with the L CSI reporting configurations. Optionally, the N CSI reporting configurations refer to: the N CSI reporting configurations with the highest / lowest priorities among the CSI reports associated with the L CSI reporting configurations. Optionally, the UE can determine the first uplink channels associated with the N CSI reporting configurations based on the priorities of the CSI reports through the following method. Set Q target is an empty set (for example, set Q target is initialized as an empty set). Define set Q as the resource set containing the L first uplink channels associated with the L CSI reporting configurations. The UE transmits on the resources of the first uplink channels determined in Q target and / or Q target . When the following steps are completed, N is equal to the number of first uplink channels in Q target .

[0345] ● Step 1: Determine the first uplink channel (q) with the highest / lowest priority among the CSI reports associated with Q and not overlapping with any resource in Q target ; exclude q from Q and add q to Q target .

[0346] ● Step 2: If Q is not an empty set or Q target < N_max, repeat Step 1; otherwise end.

[0347] Optionally, if the UE is to transmit the first uplink channels associated with each CSI reporting configuration (or at least one CSI reporting configuration) in the same time domain unit among the L CSI reporting configurations, (and the resources of the L first uplink channels overlap / are the same,) the UE transmits the first uplink channels associated with N (1≤N≤L) CSI reporting configurations among the L CSI reporting configurations based on the resource IDs (or the IDs of the associated scheduling request configurations or the associated cell IDs) associated with the L first uplink channels, and / or the second uplink channels associated with the first uplink channels associated with the N CSI reports. When N = 1, the CSI reporting configuration refers to: the CSI reporting configuration with the lowest / highest resource ID (or the ID of the associated scheduling request configuration or the associated cell ID) among the L first uplink channels associated with the L CSI reporting configurations. Optionally, the N CSI reporting configurations refer to: the N CSI reporting configurations with the lowest / highest resource ID (or the ID of the associated scheduling request configuration or the associated cell ID) among the L first uplink channels associated with the L CSI reporting configurations. Optionally, the UE can determine the method for N CSI reports based on the resource ID (or the ID of the associated scheduling request configuration or the associated cell ID) associated with the first uplink channel by the following method. Define the set Q target as an empty set. Define the set Q as the resource set of the L first uplink channels associated with the L CSI reports. The UE transmits on the resources of the first uplink channels in Q target and / or Q target determined by the following steps. When the following steps are completed, N is equal to the number of first uplink channels in Q target .

[0348] ● Step 1: Determine the first uplink channel (q) with the lowest / highest resource ID (or the ID of the associated scheduling request configuration or the associated cell ID) associated with Q and that does not overlap with any resource in Q target ; Exclude q from Q and add q to Q target .

[0349] ● Step 2: If Q is not an empty set or Q target <N_max, repeat Step 1; otherwise end.

[0350] Optionally, if the UE will transmit the first uplink channel associated with each of the L CSI reporting configurations in the same time domain unit, and the resources of the L first uplink channels are the same, then the UE will transmit the second uplink channel associated with N (1≤N≤L) CSI reporting configurations in the L CSI reporting configurations based on the priority of the CSI reports associated with the L CSI reporting configurations. When N=1, the CSI reporting configuration refers to the highest / lowest priority CSI reporting configuration among the L CSI reporting configurations. Optionally, the N CSI reporting configurations refer to the N CSI reporting configurations with the highest / lowest priority associated with the L CSI reporting configurations.

[0351] Optionally, if the resources of the L CSI reporting configurations associated with the (L) first uplink channels overlap or are identical, the UE (or the UE's MAC entity) determines / selects N first uplink channels from the L first uplink channels for transmission. Optionally, the UE transmits CSI reports associated with the first uplink channels. Optionally, N can be configured by the base station, or N can be a UE capability indicator. Optionally, N can be predefined, for example, 1 or 2. The method for determining N first uplink channels from the L first uplink channels is described above.

[0352] The above methods clarify the solution when the first uplink channel associated with multiple CSI reporting configurations conflicts, avoiding ambiguity in UE behavior caused by channel conflicts and improving the reliability of the communication system.

[0353] 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.

[0354] 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).

[0355] Optionally, at least one (or each) of the L CSI reporting configurations may indicate the resources used to transmit the first uplink channel.

[0356] 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.

[0357] 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.

[0358] 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.

[0359] 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.

[0360] 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.

[0361] 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.

[0362] 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 reported by the L CSIs 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 by 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 by 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 by the L CSI-reported configurations are identical (e.g., the serving cell IDs associated with the configuration permission configurations are identical). In this document, the BWP associated with the configuration permission configuration can be the BWP where the configuration permission configuration resides. In this document, the serving cell associated with the configuration permission configuration can be the serving cell where the configuration permission configuration resides.

[0363] 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.

[0364] 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.

[0365] 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.

[0366] 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.

[0367] 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.

[0368] 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.

[0369] 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.

[0370] 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.

[0371] 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.

[0372] 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.

[0373] 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.

[0374] Optionally, the second CSI reporting configuration can be indicated by the base station.

[0375] 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.

[0376] 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.

[0377] 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.

[0378] 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.

[0379] 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.

[0380] 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.

[0381] 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.

[0382] 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.

[0383] 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.

[0384] 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.

[0385] 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.

[0386] 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.

[0387] 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.

[0388] 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.

[0389] The priority of CSI reported configuration association can be: the priority value of the CSI reported configuration association, or the priority value of the CSI reported configuration corresponding to / associated with. The priority of CSI reported configuration association can also be: the priority value determined by the ID of the CSI reported configuration. See above for the method of determining the priority of CSI reported configuration association.

[0390] The following discusses the method for determining the computing resources associated with CSI reporting configuration. The computing resources associated with CSI reporting configuration can be: the computing resources associated with CSI reporting corresponding to the CSI reporting configuration. Optionally, the computing resources can be resources used for CSI computation. Resources used for CSI computation can be one or more CSI processing units.

[0391] In this paper, the UE's resources for parallel CSI computation are limited. The UE's available / supported parallel CSI computation resources can be reported via UE capability signaling. The number of parallel CSI computations the UE has / supports can also be reported via UE capability signaling. The number of parallel CSI computations supported by the UE is N. CPU N CPUThis can be the number of parallel CSI computations in a single CC supported by the UE (e.g., the number indicated by the parameter simultaneousCSI-ReportsPerCC). N CPU This can be the number of parallel CSI calculations across all CCs supported by the UE (e.g., the number indicated by the parameter `simultaneousCSI-ReportsAllCC`). For example, the UE can indicate the number of supported parallel CSI calculations in one CC via the parameter `simultaneousCSI-ReportsPerCC`, and / or, via the parameter `simultaneousCSI-ReportsAllCC`, the number of supported parallel CSI calculations across all CCs. CPU with parameter simultaneousCSI-ReportsPerCC in a component carrier, and / or simultaneousCSI-ReportsAllCC across all component carriers).

[0392] In this article, UE supports N CPU Parallel CSI computation refers to the UE having N CPU One CSI processing unit for handling CSI reports (if a UE supports N) CPU simultaneous CSI calculations,it is said to haveN CPU CSI processing units (CPUs) for processing CSI reports. On an OFDM symbol, if L CPUs are occupied for CSI reporting calculations, then the UE has N... CPU –L unoccupied CPUs (If L CPUs are occupied for calculation of CSI reports in a given OFDM symbol, the UE has N CPU -Lunoccupied CPUs).

[0393] In this paper, if N CSI reports start occupying their respective CPUs on the same OFDM symbol and there are N on those symbols... CPU–L CPUs are not occupied, and each CSI reports n=0,…,N-1 corresponding to O CPU If (n), then the UE is not required to update the N–M lowest priority required CSI reports, where M refers to the set of N that satisfy the condition 0≤M≤N. the maximum value. (If N CSI reports start occupying theirrespective CPUs on the same OFDM symbol on which N CPU -LCPUs are unoccupied,where each CSI reportn=0,…,N-1corresponds to O CPU (n), the UE is not required to update the N–M requested CSI reports with lowest priority, where 0≤M≤Nand M is the largest value such that ).

[0394] In this paper, a CSI report occupies a number of CPUs for a number of time domain units. Optionally, a time domain unit can be a timeslot / symbol. The number of CPUs occupied by a single CSI report can be represented as O CPU .

[0395] The following discusses the amount of CPU time reported by CSI (O CPU CSI reporting can be carried by the second uplink channel. CSI reporting can also be associated with L CSI reporting configurations. See above for related descriptions.

[0396] The number of CPUs used by CSI (O) CPU The value can be a third or fourth value. Optionally, when L=1, the CSI reports the number of CPUs used (O). CPU () can be a third value. Optionally, when L>1, the CSI reports the number of CPUs used (O) CPU The third value can be a fourth value. Optionally, the third value is different from the fourth value. Optionally, the third value can be equal to one of 0, 1, 2, 3, 4, 5, 6, 7, or 8. Optionally, the fourth value can be equal to one of 0, 1, 2, 3, 4, 5, 6, 7, or 8.

[0397] Optionally, the fourth value can be predefined, or it can be a UE capability indicator or a base station indicator.

[0398] Optionally, the fourth value can be determined based on the L CSI reported configurations. Optionally, the fourth value can be an O value associated with the L CSI reported configurations. CPU Confirmed. Optionally, L CSIs report configuration-associated O. CPU It can be L CSI reporting configurations, each associated with one of L O. CPU Optionally, the fourth value can be an O value associated with the L CSI reporting configurations. CPU The sum. Optionally, the fourth value can be the O associated with each of the L CSI reporting configurations. CPU The sum. For example, the fourth value equals... Or, L·O l , of which O l This refers to the O associated with the l-th CSI reporting configuration out of L CSI reporting configurations. CPU Optionally, CSI reports the configuration associated with O. CPU It can be predefined, indicated by UE capabilities, or indicated by the base station. Optionally, O l It can be predefined, indicated by UE capabilities, or indicated by the base station.

[0399] Optionally, the fourth value can be determined based on the first CSI reporting configuration or the second CSI reporting configuration. For example, the fourth value is equal to the O value associated with the first CSI reporting configuration. CPU For example, the fourth value is equal to the O value associated with the configuration reported by the second CSI. CPU Optionally, the first CSI reports the configuration associated with O. CPU This can be predefined, indicated by UE capabilities, or indicated by the base station. Optionally, the second CSI reports configuration-associated O. CPU It can be predefined, indicated by UE capabilities, or indicated by the base station.

[0400] Optionally, the fourth value can be the O associated with the L CSI reporting configurations. CPU The maximum value among them. Optionally, the fourth value can be the O value associated with each of the L CSI reporting configurations. CPU The maximum value among them.

[0401] For example, the fourth value equals Among them, O l This refers to the O associated with the l-th CSI reporting configuration out of L CSI reporting configurations. CPU For example, the fourth value equals Among them, O l This refers to the O associated with the l-th CSI reporting configuration out of L CSI reporting configurations.CPU Q refers to the set including 1, 2, ..., L. Optionally, CSI reports the configuration associated with O. CPU It can be predefined, indicated by UE capabilities, or indicated by the base station. Optionally, O l It can be predefined, indicated by UE capabilities, or indicated by the base station.

[0402] Optionally, the fourth value can be the O associated with the L CSI reporting configurations. CPU The minimum value among them. Optionally, the fourth value can be the O value associated with each of the L CSI reporting configurations. CPU The minimum value among them.

[0403] Optionally, the fourth value can be the O associated with the L CSI reporting configurations. CPU The average value. Optionally, the fourth value can be the O value associated with each of the L CSI reporting configurations. CPU The average value. Optionally, this average value can be rounded, for example, rounded up or rounded down.

[0404] Optionally, L CSIs report configuration associated O CPU They are the same. Optionally, the L CSI reporting configurations are respectively associated with the O CPU They are the same. Optionally, the fourth value can be the O associated with each of the L CSI reporting configurations. CPU One of them.

[0415] The above method ensures that, when L>1, the UE and the base station have the same understanding of the time-domain units of the CPU occupied by the CSI reports. This avoids the base station scheduling based on incorrect time-domain units of the occupied CPU, which could lead to some CSI reports being incorrectly discarded due to insufficient available CPU, thus improving the reliability of the communication system.

[0416] In some cases, the UE can report UE capabilities (e.g., UE capability signaling), where the UE capability indicates the maximum number (e.g., total number) of reference signaling resources supported by the UE. Optionally, the UE capability signaling indicates the maximum number (e.g., total number) of reference signaling resources supported in a time-domain element. Optionally, the reference signaling resources can be: SSB resources and / or CSI-RS resources.

[0417] Optionally, in any time-domain element, the UE is not expected to have more SSB / CSI-RS resources within a slot (in active BWPs) than the reported capability. Optionally, in any time-domain element, the UE determines that the SSB / CSI-RS resources do not exceed the reported capability. Optionally, in any time-domain element (e.g., time slot), the number of reference signal resources transmitted by the base station does not exceed the number of reported capability indications. The counting method for reference signal resources (for UE capabilities) associated with indicated TCI states is discussed below. The description / determination method for reference signal resources associated with indicated TCI states is given above. To determine the number of reference signal transmissions in a time-domain cell (so as not to exceed the number of reference signals transmitted in a time-domain cell as indicated by the UE capability above), the counting method for the reference signals associated with the indicated TCI state is described below.

[0418] Optionally, when the UE is configured with a CSI reporting configuration for UE-initiated CSI reporting, the reference signal resources (for UE capabilities) associated with the indicated TCI state are counted.

[0419] Optionally, if the UE is configured with a CSI reporting configuration for UE-initiated CSI reporting, and the reference signal associated with the indicated TCI state is transmitted on a time domain cell, and the indicated TCI state is used / applied on that time domain cell, then the reference signal is counted on that time domain cell. For example, CSI-RS#1 can be transmitted on time slots #1 and #6, and CSI-RS#1 is associated with the indicated TCI state #1, and TCI state #1 is applied on time slots #4 to #8, then CSI-RS#1 is counted on time slot #6. That is, to ensure that the number of reference signals transmitted in a time slot does not exceed the number indicated by the UE capability, CSI-RS#1 is counted / considered on time slot #6.

[0420] Optionally, if the UE is configured with X CSI reporting configurations for UE-initiated CSI reporting, and the reference signal associated with the indicated TCI state is transmitted on a time domain element, and the indicated TCI state is used / applied on that time domain element, then the reference signal is counted X times in that time domain element (or, is counted an additional X times, or the CSI reporting configuration for UE-initiated CSI reporting is counted X times). Optionally, X ≥ 1.

[0421] For example, the UE is configured with 5 CSI reporting configurations for UE-initiated CSI reporting.

[0422] CSI-RS#1 can be transmitted in time slots #1 and #6. Furthermore, CSI-RS#1 is associated with the indicated TCI state #1, and since TCI state #1 is applied in time slots #4 to #8, CSI-RS#1 is counted 5 times in time slot #6. In other words, to determine the number of reference signals transmitted in a time-domain unit (so as not to exceed the number indicated by the UE capability mentioned above), CSI-RS#1 is counted as being transmitted 5 times in time slot #6.

[0423] The above method clarifies the counting method for reference signals associated with the indicated TCI state, so that the UE and the base station have the same understanding of the number of times the reference signals are transmitted, avoiding the base station from transmitting more reference signals than the UE can support in a time domain unit, thus improving the reliability of the communication system.
