Description

Technical Field

[0001] The present disclosure relates to wireless communication technologies, and more particularly, to a method and an apparatus for reporting beam-related information in a wireless communication system. Background Art

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

[0003] The 5G communication system is implemented in a higher frequency (millimeter wave, mmWave) band (e.g., 60 GHz band) to achieve higher data rates. To reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technologies are discussed in the 5G communication system.

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

[0064] The text and the drawings are provided only as examples to assist the reader in understanding the present disclosure. They are not intended and should not be construed as limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art based on the content disclosed herein that changes can be made to the illustrated embodiments and examples without departing from the scope of the present disclosure.

[0065] The following Figures 1 - 3B describes various embodiments implemented by using orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) communication techniques in a wireless communication system. Figures 1 - 3B The description does not imply a physical or architectural hint about the manner in which different embodiments can be implemented. Different embodiments of the present disclosure can be implemented in any suitably arranged communication system.

[0066] Figure 1 FIG. shows an example wireless network 100 according to some embodiments of the present disclosure. Figure 1 The embodiment of the wireless network 100 shown in is for illustration only. Other embodiments of the wireless network 100 can be used without departing from the scope of the present disclosure.

[0067] The 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 networks).

[0068] Depending on the network type, other well-known terms such as "base station" or "access point" can be used in place 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 to remote terminals. And, 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 in place of "user equipment" or "UE". For example, the terms "terminal", "user equipment", and "UE" can be used in this patent document to refer to a remote wireless device that wirelessly accesses a gNB, whether the UE is a mobile device (such as a mobile phone or a smart phone) or a device that is generally considered fixed (such as a desktop computer or a vending machine).

[0069] gNB 102 provides wireless broadband access to network 130 for a first plurality of user equipment (UEs) within gNB 102's coverage area 120. The first plurality of UEs includes: 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, or wireless PDA. gNB 103 provides wireless broadband access to network 130 for a second plurality of UEs within gNB 103's coverage area 125. The second plurality of UEs includes UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 may be capable of communicating with each other and with UEs 111-116 using 5G, Long Term Evolution (LTE), LTE-A, WiMAX, or other advanced wireless communication technologies.

[0070] The dashed lines illustrate the approximate extents of coverage areas 120 and 125, which are shown as approximately circular for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with gNBs, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0071] As described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 supports codebook design and structure for systems with 2D antenna arrays.

[0072] although Figure 1 One example of a wireless network 100 is shown, but Figure 1 Various changes may 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. Furthermore, gNBs 101, 102, and / or 103 can provide access to other or additional external networks, such as an external telephone network or other type of data network.

[0073] Figure 2A and Figure 2BFIG. 0 shows an example wireless transmit and receive path in accordance with some embodiments of the present disclosure. In the following description, the transmit path 200 can be described as being implemented in a gNB (such as gNB 102), while the receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that the receive path 250 can be implemented in a gNB and the transmit path 200 can be implemented in a UE. In some embodiments, the receive path 250 is configured to support codebook designs and structures for systems with 2D antenna arrays as described in embodiments of the present disclosure.

[0074] 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 upconverter (UC) 230. The receive path 250 includes a downconverter (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.

[0075] In the transmit path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as low density parity check (LDPC) coding), and modulates the input bits (such as using quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a sequence of frequency domain modulation symbols. The serial-to-parallel (S-to-P) block 210 converts (such as demultiplexes) the serial modulation symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in gNB 102 and UE 116. The N-point IFFT block 215 performs an IFFT operation on the N parallel symbol streams to generate a time domain output signal. The parallel-to-serial block 220 converts (such as multiplexes) the parallel time domain output symbols from the N-point IFFT block 215 to generate a serial time domain signal. The cyclic prefix addition block 225 inserts a cyclic prefix into the time domain signal. The upconverter 230 modulates (such as upconverts) the output of the cyclic prefix addition block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at baseband before being upconverted to the RF frequency.

[0076] The RF signal transmitted from gNB 102 arrives at UE 116 after passing through the wireless channel, and operations opposite to those at gNB 102 are performed at UE 116. The downconverter 255 downconverts the received signal to the baseband frequency, and the cyclic prefix block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. The serial-to-parallel block 265 converts the time-domain baseband signal to a parallel time-domain signal. The N-point FFT block 270 performs the FFT algorithm to generate N parallel frequency-domain signals. The parallel-to-serial block 275 converts the parallel frequency-domain signals to a sequence of modulated data symbols. The channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0077] Each of gNBs 101 - 103 can implement a transmit path 200 similar to that for transmitting to UEs 111 - 116 in the downlink, and can implement a receive path 250 similar to that for receiving from UEs 111 - 116 in the uplink. Similarly, each of UEs 111 - 116 can implement a transmit path 200 for transmitting to gNBs 101 - 103 in the uplink, and can implement a receive path 250 for receiving from gNBs 101 - 103 in the downlink.

[0078] Figure 2A and Figure 2B Each of the components in can be implemented using only hardware, or using a combination of hardware and software / firmware. As a specific example, Figure 2A and Figure 2B At least some of the components in can be implemented in software, while other components can be implemented by configurable hardware or a hybrid of software and configurable hardware. For example, the FFT block 270 and the IFFT block 215 can be implemented as configurable software algorithms, where the value of the number of points N can be modified according to the implementation.

[0079] Furthermore, although described as using FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of the present disclosure. Other types of transforms can be used, such as the discrete Fourier transform (DFT) and the inverse discrete Fourier transform (IDFT) functions. It should be understood that for the DFT and IDFT functions, the value of the variable N can be any integer (such as 1, 2, 3, 4, etc.), while for the FFT and IFFT functions, the value of the variable N can be any integer that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0080] Although Figure 2A and Figure 2B show examples of wireless transmit and receive paths, various changes can be made to Figure 2A and Figure 2B For example,Figure 2A and Figure 2B The various components in can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. Moreover, Figure 2A and Figure 2B are intended to show examples of types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.

[0081] Figure 3A An example UE 116 according to some embodiments of the present disclosure is shown. Figure 3A The embodiment of UE 116 shown in is for illustration only, and Figure 1 UEs 111 - 115 can have the same or similar configurations. However, UEs have a wide variety of configurations, and Figure 3A the scope of the present disclosure is not limited to any particular implementation of a UE.

[0082] UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a transmit (TX) processing circuit 303, a microphone 304, and a receive (RX) processing circuit 305. UE 116 also includes a speaker 306, a controller / processor 307, an input / output (I / O) interface 308, (one or more) input devices 309, a display 310, and a memory 311. The memory 311 includes an operating system (OS) 312 and one or more applications 313.

[0083] RF transceiver 302 receives an incoming RF signal transmitted by the gNB of wireless network 100 from antenna 301. RF transceiver 302 down-converts the incoming RF signal to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to RX processing circuit 305, where RX processing circuit 305 generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuit 305 sends the processed baseband signal to speaker 306 (such as for voice data) or to controller / processor 307 (such as for web browsing data) for further processing.

[0084] TX processing circuit 303 receives analog or digital voice data from microphone 304, or other outgoing baseband data (such as network data, emails, or interactive video game data) from controller / processor 307. TX processing circuit 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceiver 302 receives the outgoing processed baseband or IF signal from TX processing circuit 303 and up-converts the baseband or IF signal to an RF signal transmitted via antenna 301.

[0085] The controller / processor 307 can include one or more processors or other processing devices and execute the OS 312 stored in the memory 311 to control the overall operation of the UE 116. For example, the controller / processor 307 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceiver 302, the RX processing circuit 305, and the TX processing circuit 303 according to well-known principles. In some embodiments, the controller / processor 307 includes at least one microprocessor or microcontroller.

[0086] The controller / processor 307 can also execute other processes and programs resident in the memory 311, such as operations for channel quality measurement and reporting for a system with a 2D antenna array as described in embodiments of the present disclosure. The controller / processor 307 can move data into or out of the memory 311 as needed for the execution of processes. In some embodiments, the controller / processor 307 is configured to execute the application 313 based on the OS 312 or in response to signals received from the gNB or the operator. The controller / processor 307 is also coupled to the I / O interface 308, where the I / O interface 308 provides the UE 116 with the ability to connect to other devices such as laptop computers and handheld computers. The I / O interface 308 is the communication path between these accessories and the controller / processor 307.

[0087] The controller / processor 307 is also coupled to the (one or more) input devices 309 and the display 310. The operator of the UE 116 can use the (one or more) input devices 309 to input data into the UE 116. The display 310 can be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). The memory 311 is coupled to the controller / processor 307. A portion of the memory 311 can include random access memory (RAM), while another portion of the memory 311 can include flash memory or other read-only memory (ROM).

[0088] Although Figure 3A an example of the UE 116 is shown, various changes can be made to Figure 3A it. For example, Figure 3A the various components in Figure 3A can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. As a specific example, the controller / processor 307 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Moreover, although

[0089] In some embodiments, two or more UEs 116 may communicate directly using one or more sidelink channels (e.g., without using a base station as a medium for communicating with each other). For example, UEs 116 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In such cases, UEs 116 may perform scheduling operations, resource selection operations, and / or other operations performed by a base station described elsewhere herein. For example, a base station may configure UEs 116 via downlink control information (DCI), radio resource control (RRC) signaling, media access control - control element (MAC-CE), or via system information (e.g., system information block (SIB)).

[0090] Figure 3B FIG. shows an example gNB 102 according to some embodiments of the present disclosure. Figure 3B The embodiment of the gNB 102 shown in is for illustration only, and Figure 1 other gNBs can have the same or similar configurations. However, gNBs have a wide variety of configurations, and Figure 3B do not limit the scope of the present disclosure to any particular embodiment of the gNB. It should be noted that gNB 101 and gNB 103 can include structures the same as or similar to those of gNB 102.

[0091] As Figure 3B shown in, gNB 102 includes a plurality of antennas 370a - 370n, a plurality of RF transceivers 372a - 372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376. In certain embodiments, one or more of the plurality of antennas 370a - 370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0092] RF transceivers 372a - 372n receive incoming RF signals, such as signals transmitted by UEs 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, where RX processing circuitry 376 generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 376 sends the processed baseband signal to controller / processor 378 for further processing.

[0093] The TX processing circuitry 374 receives analog or digital data (such as voice data, network data, e-mail, or interactive video game data) from the controller / processor 378. The TX processing circuitry 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceivers 372a - 372n receive the outgoing processed baseband or IF signal from the TX processing circuitry 374 and up-convert the baseband or IF signal into an RF signal transmitted via the antennas 370a - 370n.

[0094] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceivers 372a - 372n, the RX processing circuitry 376, and the TX processing circuitry 374 according to well-known principles. The controller / processor 378 can also support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 378 can perform BIS processes, such as those performed by a blind interference sensing (BIS) algorithm, and decode the received signals from which interference signals have been subtracted. The controller / processor 378 can support any one of a variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0095] The controller / processor 378 can also execute programs and other processes residing in the memory 380, such as a basic OS. The controller / processor 378 can also support channel quality measurement and reporting for systems with a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTC. The controller / processor 378 can move 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 over any suitable wired or wireless connection. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G or new radio access technology or NR, LTE or LTE-A), the backhaul or network interface 382 is capable of allowing 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 is capable of allowing the gNB 102 to communicate with a larger network (such as the Internet) via a wired or wireless local area network or via a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication over a wired or wireless connection, such as an Ethernet or RF transceiver.

[0097] The memory 380 is coupled to the controller / processor 378. A portion of the memory 380 can include RAM, while another portion of the memory 380 can include flash memory or other ROM. In certain embodiments, multiple instructions, such as BIS algorithms, are stored in the memory. The multiple instructions are configured to cause the controller / processor 378 to perform a BIS process and decode a 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 communication aggregation with FDD cells and TDD cells.

[0099] Although Figure 3B an example of the gNB 102 is shown, various changes can be made to Figure 3B it. For example, the gNB 102 can include any number of Figure 3A each of the components shown in. As a specific example, an access point can include many backhaul or network interfaces 382, and the controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as including a single instance of TX processing circuitry 374 and a single instance of RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0100] Those skilled in the art can understand that the "terminal" and "terminal device" used herein include both devices with a wireless signal receiver that only has the ability to receive and no transmitting ability, and hardware devices with receiving and transmitting capabilities that can perform two-way communication on a two-way communication link.

[0101] With the rapid development of the information industry, especially the growing demand from the mobile Internet and the Internet of Things (IoT), unprecedented challenges have been brought to future mobile communication technologies. To address these unprecedented challenges, the communication industry and academia have launched extensive research on the fifth-generation mobile communication technology (5G) for the 2020s. Currently, in the ITU report ITU-R M.[IMT.VISION], the framework and overall goals of future 5G are being discussed, which details the demand outlook, application scenarios, and various important performance indicators of 5G. Regarding the new requirements in 5G, the ITU report ITU-R M.[IMT.FUTURE TECHNOLOGY TRENDS] provides information related to the technology trends of 5G, aiming to address significant issues such as a significant increase in system throughput, user experience consistency, scalability to support IoT, latency, energy efficiency, cost, network flexibility, support for emerging services, and flexible spectrum utilization. In the 3rd Generation Partnership Project (3GPP), the first-phase work on 5G has been underway. To support more flexible scheduling, 3GPP has decided to support variable Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) feedback latency in 5G. In the existing Long Term Evolution (LTE) system, the time from the reception of downlink data to the uplink transmission of HARQ-ACK is fixed. For example, in a Frequency Division Duplex (FDD) system, the latency is 4 subframes, and in a Time Division Duplex (TDD) system, according to the uplink and downlink configuration, a HARQ-ACK feedback latency is determined for the corresponding downlink subframe. In a 5G system, whether it is an FDD or a TDD system, for a given downlink time unit (e.g., a downlink slot or a downlink mini-slot; or, for example, a Physical Downlink Shared Channel (PDSCH) time unit), the uplink time unit for HARQ-ACK feedback (e.g., a Physical Uplink Control Channel (PUCCH) time unit) is variable. For example, the latency of HARQ-ACK feedback can be dynamically indicated by physical layer signaling, or different HARQ-ACK latencies can be determined based on factors such as different services or user capabilities.

[0102] 3GPP has defined three major directions for 5G application scenarios - eMBB (enhanced mobile broadband), mMTC (massive machine-type communication), and URLLC (ultra-reliable and low-latency communication). The eMBB scenario aims to further improve the data transmission rate based on the existing mobile broadband service scenario to enhance the user experience, thus pursuing an extreme communication experience between people. mMTC and URLLC are application scenarios such as the Internet of Things, but with different focuses: mMTC is mainly for information interaction between humans and things, and URLLC mainly reflects the communication requirements between things.

[0103] In a communication system, a UE can receive a reference signal (RS), perform channel measurement based on the RS, and estimate the channel state based on the channel measurement to obtain channel state information (CSI). The UE can determine (e.g., calculate or derive) CSI parameters and send a CSI report including the CSI parameters. For example, the RS can include CSI-RS, synchronization signal block (SSB), demodulation reference signal (DM-RS), phase-tracking reference signal (PT-RS), and / or the like. The CSI can include one or more of the following: channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), synchronization signal (SS) / physical broadcast channel (PBCH) block resource indicator (SSBRI), layer indicator (LI), rank indicator (RI), reference signal received power (RSRP), or signal-to-interference-plus-noise ratio (SINR).

[0104] In some cases, the channel state of the network may change dynamically, and how to quickly report the channel state of the network is a problem to be solved. Therefore, an enhanced uplink signal transmission method is needed to report CSI.

For example, the UE transmits uplink data and / or uplink control signaling to the base station on the determined time unit. As another example, the UE transmits uplink data and / or uplink control signaling to the base station on the determined time unit according to the determined transmission power.

[0164] [HARQ / Scheduling General Timing]

[0165] In some embodiments, operations S710 and / or S720 and / or S730 may be performed based on the methods described according to various exemplary embodiments of the present disclosure (e.g., the various manners described below).

[0166] In some embodiments, method 700 may omit one or more of operations S710, S720, or S730, or may include additional operations, e.g., operations performed by the UE (terminal) based on the methods described according to various exemplary embodiments of the present disclosure (e.g., the various manners described below).

[0167] In some embodiments, the acknowledgment / negative acknowledgment (ACK / NACK) for downlink transmission may be performed via HARQ-ACK.

[0168] Reference will be made below to Figures 8A - 8C Describe some examples of uplink transmission timing according to some exemplary embodiments of the present disclosure.

[0169] In one example, the UE receives DCI and receives PDSCH according to the time-domain resources indicated in the DCI. For example, the parameter K0 may indicate the time unit interval (offset) between the PDSCH scheduled by the DCI and the DCI (e.g., the PDCCH carrying the DCI), and the unit of K0 may be a time slot. For example, the time slot of the PDSCH (i.e., the time slot of the active BWP of the serving cell where the PDSCH is located). For example, Figure 8A An example of K0 = 1 is given. In Figure 8A In the example shown, the time unit interval from the PDSCH scheduled by the DCI to the PDCCH carrying the DCI is 1 time slot. In the exemplary embodiments of the present disclosure, "the UE receives DCI" may mean "the UE detects DCI".

[0170] In another example, the UE receives DCI and transmits a PUSCH according to the time-domain resources indicated in the DCI. For example, a timing parameter K2 can be used to indicate the time-unit interval between the DCI-scheduled PUSCH and the DCI (e.g., the PDCCH carrying the DCI), and the unit of K2 can be a time slot. For example, the time slot of the PUSCH (i.e., the time slot of the active BWP of the serving cell where the PUSCH is located). For example, Figure 8B An example where K2 = 1 is given. In Figure 8B In the example shown, the time-unit interval between the DCI-scheduled PUSCH and the PDCCH carrying the DCI is 1 time slot. K2 can also represent the time-unit interval between the PDCCH activating a configured grant (CG) PUSCH and the first activated CG PUSCH (e.g., the CG PUSCH transmission occasion). In the examples of the present disclosure, if not specifically stated, the PUSCH can be a dynamically scheduled (e.g., DCI-scheduled) PUSCH (e.g., in the description of the exemplary embodiments of the present disclosure, it can be referred to as a dynamic grant (DG) PUSCH) and / or a PUSCH not scheduled by DCI (e.g., a CG PUSCH).

[0171] In yet another example, the UE receives a PDSCH and can send the HARQ-ACK information received for the PDSCH on a PUCCH in a time unit (e.g., an uplink time unit). For example, a timing parameter (which can also be referred to as a timing value) K1 (e.g., a higher-layer parameter dl-DataToUL-ACK) can be used to indicate the time-unit interval between the PUCCH carrying the HARQ-ACK information received for the PDSCH and the PDSCH, and the unit of K1 can be a time unit (e.g., an uplink time unit) (e.g., the time unit of the PUCCH), such as a time slot or a sub-slot. For example, Figure 8A An example where K1 = 3 is given. In Figure 8A In the example shown, the time-unit interval between the PUCCH carrying the HARQ-ACK information received for the PDSCH and the PDSCH is 3 time slots. It should be noted that in the description of the exemplary embodiments of the present disclosure, the timing parameter K1 can be used interchangeably with the time-unit offset K1, the timing parameter K0 can be used interchangeably with the time-unit offset K0, and the timing parameter K2 can be used interchangeably with the time-unit offset K2.

[0172] The PDSCH can be the PDSCH scheduled by DCI and / or the SPS (Semi-Persistent Scheduling) PDSCH. After the SPS PDSCH is activated by DCI, the UE will receive the SPS PDSCH periodically. In the example of the present disclosure, the SPS PDSCH can be equivalent to the PDSCH without DCI / PDCCH scheduling. After the SPS PDSCH is released (deactivated), the UE no longer receives the SPS PDSCH.

[0173] In the description of the exemplary embodiments of the present disclosure, the HARQ-ACK can be the HARQ-ACK for SPS PDSCH reception (e.g., HARQ-ACK without DCI indication) and / or the HARQ-ACK indicated by a DCI format (e.g., the HARQ-ACK for the PDSCH received by a DCI format scheduling, where the PDSCH reception can be the PDSCH reception providing a transport block with enabled HARQ-ACK information). Again, for example, the HARQ-ACK of a DCI format that does not schedule the PDSCH).

[0174] In another example, the UE receives a DCI (e.g., a DCI indicating the release (deactivation) of the SPS PDSCH) and sends the HARQ-ACK information of the DCI on the PUCCH in a time unit (e.g., an uplink time unit). For example, the timing parameter K1 can be used to represent the time unit interval between the PUCCH carrying the HARQ-ACK information of the DCI and the DCI. The unit of K1 can be a time unit (e.g., an uplink time unit), such as a slot or a sub-slot. For example, Figure 8C An example of K1 = 3 is given. In Figure 8C the example, the time unit interval between the PUCCH carrying the HARQ-ACK information of the DCI and the DCI is 3 slots. For example, the timing parameter K1 can be used to represent the time unit interval between the PDCCH reception of the DCI indicating the release (deactivation) of the SPS PDSCH and the PUCCH that feeds back its HARQ-ACK.

[0175] In some embodiments, at operation S720, the UE may report (or signal / transmit) the UE capability to the base station or indicate the UE capability. For example, the UE reports (or signals) the UE capability to the base station by transmitting a PUSCH. In this case, the UE capability information is included in the PUSCH transmitted by the UE. A UE capability may be a UE capability parameter or a value of a UE capability parameter.

[0176] In some embodiments, the base station may configure higher layer signaling for the UE according to the UE capability received from the UE.

[0177] In some embodiments, the downlink channel (downlink resource) may include PDCCH and / or PDSCH. The uplink channel (uplink resource) may include PUCCH and / or PUSCH.

[0178] [Two-level priority]

[0179] In some embodiments, the UE may be configured with two-level priority for uplink transmission. For example, the UE is configured with a higher layer parameter PUCCH-ConfigurationList, where the PUCCH resources configured by the first PUCCH-Config are PUCCH resources with lower priority, and the PUCCH resources configured by the second PUCCH-Config are PUCCH resources with higher priority. For another example, the priority of a PUCCH or PUSCH may be indicated in DCI. For example, it may be indicated by a physical layer priority index (phy-PriorityIndex) field.

[0180] When two or more uplink physical channels overlap on a serving cell (e.g., overlap in time), or when the PUCCH and PUSCH overlap (e.g., overlap in time), it is necessary to resolve the overlapping for physical channels. "Resolving the overlapping for physical channels" can be understood as "resolving the conflicts of overlapping physical channels". The resulting physical channels after resolving the overlapping of physical channels have no overlap or no conflicts. The overlapping of physical channels can be resolved by multiplexing and / or prioritization. Multiplexing can be to multiplex the UCI in two or more physical channels into one physical channel. For example, multiplexing multiple PUCCHs and / or PUSCHs that overlap in the time domain can include multiplexing the UCI information in the PUCCH into one PUCCH or PUSCH. It should be noted that in the description of the exemplary embodiments of the present disclosure, "resolving the overlapping of physical channels" can be used interchangeably with "determining the overlapping of physical channels". Prioritization can be to transmit a physical channel with a higher priority and not transmit a physical channel with a lower priority. It should be noted that in the description of the exemplary embodiments of the present disclosure, "not transmitting a physical channel", "canceling the transmission of a physical channel", "stopping the transmission of a physical channel" and "reducing the priority of a physical channel" can be used interchangeably. For example, the UE performing prioritization on two PUCCHs and / or PUSCHs that overlap in the time domain can include the UE transmitting a PUCCH or PUSCH with a higher priority, and / or the UE not transmitting a PUCCH or PUSCH with a lower priority. In the embodiments of the present disclosure, if not otherwise stated, "resolving the overlapping of physical channels" can be understood as resolving the overlapping of physical channels with the same physical layer priority.

[0181] In some embodiments, if the UE is instructed by higher layer signaling (e.g., via the higher layer parameter uci-MuxWithDiffPrio) to multiplex UCIs (e.g., HARQ-ACK) with different priorities when resolving the overlapping of physical channels with different priorities, the UE can multiplex the UCIs (e.g., HARQ-ACK) with different priorities; otherwise (e.g., if the UE is not configured with a parameter for multiplexing UCIs with different priorities (e.g., uci-MuxWithDiffPrio)), when resolving the overlapping of physical channels with different priorities, the UE performs prioritization on PUCCHs and / or PUSCHs with different priorities.

[0182] For example, two levels of priorities may include a first priority and a second priority that are different from each other. In one example, the first priority may be higher than the second priority, that is, the first priority is the higher priority and the second priority is the lower priority. In another example, the first priority may be lower than the second priority. However, embodiments of the present disclosure are not limited thereto. For example, a UE may be configured with more than two levels of priorities. For the purpose of convenience, in some exemplary embodiments of the present disclosure, the description is made considering that the first priority is higher than the second priority. It should be noted that all embodiments of the present disclosure are applicable to the case where the first priority may be higher than the second priority; all embodiments of the present disclosure are applicable to the case where the first priority may be lower than the second priority; all embodiments of the present disclosure are applicable to the case where the first priority may be equal to the second priority. In some exemplary embodiments of the present disclosure, "first priority", "higher priority", "larger priority index", and "priority index 1" may be used interchangeably. In some exemplary embodiments of the present disclosure, "second priority", "lower priority", "smaller priority index", and "priority index 0" may be used interchangeably.

[0183] [Sub-slot]

[0184] In some embodiments, a UE may be configured for PUCCH transmission based on a sub-slot. For example, the sub-slot length parameter of each PUCCH configuration parameter in the first PUCCH configuration parameter and the second PUCCH configuration parameter (in the description of the exemplary embodiments of the present disclosure, may also be referred to as a parameter related to the sub-slot length) (for example, the higher layer parameter subslotLengthForPUCCH) may be 7 OFDM symbols, or 6 OFDM symbols, or 2 OFDM symbols. The sub-slot configuration length parameters in different PUCCH configuration parameters may be configured separately. If the sub-slot length parameter is not configured in a PUCCH configuration parameter, the scheduling time unit of this PUCCH configuration parameter is defaulted to one time slot. If the sub-slot length parameter is configured in a PUCCH configuration parameter, the scheduling time unit of this PUCCH configuration parameter is L (L is the configured sub-slot configuration length) OFDM symbols.

[0185] The mechanisms of slot-based PUCCH transmission and sub-slot-based PUCCH transmission are basically the same. In this disclosure, a slot can be used to represent a PUCCH occasion unit. For example, if a UE is configured with sub-slots, the slot serving as the PUCCH occasion unit can be replaced with a sub-slot. For example, it can be specified by the protocol that if a UE is configured with a sub-slot length parameter (e.g., the higher layer parameter subslotLengthForPUCCH), unless otherwise specified, the number of symbols included in the slot for PUCCH transmission is indicated by the sub-slot length parameter.

[0186] For example, if a UE is configured with a sub-slot length parameter, and sub-slot n is the last uplink sub-slot overlapping with a PDSCH reception or a PDCCH reception (e.g., SPS PDSCH release, and / or indicating secondary cell dormancy, and / or triggering a type-3 HARQ-ACK codebook report and there is no scheduled PDSCH reception), then the HARQ-ACK information for this PDSCH reception or PDCCH reception is sent in uplink sub-slot n + k, where k is determined by the timing parameter K1 (for the definition of the timing parameter K1, reference can be made to the previous description). Another example, if a UE is not configured with a sub-slot length parameter, and slot n is the last uplink slot overlapping with the downlink slot where the PDSCH reception or PDCCH reception is located, then the HARQ-ACK information for this PDSCH reception or PDCCH reception is sent in uplink slot n + k, where k is determined by the timing parameter K1.

[0187] [Multicast Service (MBS)]

[0188] In the description of the exemplary embodiments of the present disclosure, unicast may refer to a manner in which a network communicates with a single UE, and multicast (multicast or groupcast) may refer to a manner in which a network communicates with multiple UEs. For example, a unicast PDSCH may be a PDSCH received by a single UE, and the scrambling of the PDSCH may be based on a UE-specific radio network temporary identifier (RNTI), such as a cell-RNTI (C-RNTI). A multicast PDSCH may be a PDSCH received by more than one UE simultaneously, and the scrambling of the multicast PDSCH may be based on an RNTI common to a UE group. For example, the RNTI common to a UE group for scrambling a multicast PDSCH may include an RNTI for scrambling a dynamically scheduled multicast transmission (e.g., PDSCH) (which may be referred to as a group RNTI (G-RNTI) in the description of the exemplary embodiments of the present disclosure) or an RNTI for scrambling a multicast SPS transmission (e.g., SPS PDSCH) (which may be referred to as a group configured scheduling RNTI (G-CS-RNTI) in the description of the exemplary embodiments of the present disclosure). The UCI of a unicast PDSCH may include HARQ-ACK information, SR, or CSI received for the unicast PDSCH. The UCI of a multicast PDSCH may include HARQ-ACK information received for the multicast PDSCH. In the description of the exemplary embodiments of the present disclosure, "multicast" may also be replaced with "broadcast".

[0189] [HARQ-ACK codebook]

[0190] In operation S710, the UE may receive downlink data (e.g., downlink data carried by PDSCH) and / or downlink control signaling (e.g., DCI format carried by PDCCH) from the base station.

[0191] In operation S720, the UE determines the HARQ-ACK information bits to be transmitted in an uplink time slot based on the downlink data and / or downlink control signaling. The determination of the HARQ-ACK information bits to be transmitted in an uplink time slot includes at least one of the following:

[0192] - Determining the value of the HARQ-ACK information bits;

[0193] - Determining the order of the HARQ-ACK information bits;

[0194] - Determining the total number of HARQ-ACK information bits.

[0195] In operation S730, the UE sends HARQ-ACK information bits to the base station. Among them, the UE can transmit HARQ-ACK information bits on PUCCH or PUSCH.

[0196] In some embodiments, the HARQ-ACK codebook may include HARQ-ACK information (which may also be referred to as HARQ-ACK information bits in this disclosure) for one or more PDSCH receptions and / or DCI formats (e.g., DCI formats without scheduling PDSCH reception). The HARQ-ACK information for a PDSCH reception may be understood as the HARQ-ACK information for the transport block (TB) included in the PDSCH reception. In the case where the UE is configured with PDSCH code block group (CBG) transmission (e.g., the parameter PDSCH-CodeBlockGroupTransmission is configured), or in the case where a PDSCH reception includes one or more CBGs, the HARQ-ACK information for the PDSCH reception may be understood as the HARQ-ACK information for the CBGs included in the PDSCH reception. If the HARQ-ACK information for one or more PDSCH receptions and / or DCI formats is indicated (or multiplexed) to be transmitted in one (e.g., the same) time unit (e.g., an uplink time unit) (e.g., transmitted on the PUCCH in the same time unit), the UE may generate the HARQ-ACK codebook according to predefined rules. The UE generating the HARQ-ACK codebook includes sorting the HARQ-ACK information bits and / or compressing (e.g., bundling) the HARQ-ACK information bits. For example, if the TB or CBG in a PDSCH reception is successfully decoded, the HARQ-ACK information for the TB or CBG in this PDSCH reception is a positive ACK. For example, a positive ACK may be represented by 1 in the HARQ-ACK codebook. If the TB or CBG in a PDSCH reception is not successfully decoded, the HARQ-ACK information for the TB or CBG in this PDSCH reception is a negative ACK (NACK). For example, NACK may be represented by 0 in the HARQ-ACK codebook. For example, the UE may generate the HARQ-ACK codebook according to the pseudo-code specified by the protocol. In one example, if the UE receives a DCI format that indicates SPS PDSCH release (deactivation), the UE transmits the HARQ-ACK information (ACK) for this DCI format. In another example, if the UE receives a DCI format that indicates secondary cell dormancy, the UE transmits the HARQ-ACK information (ACK) for this DCI format.In another example, if the UE receives a DCI format that indicates the transmission of HARQ-ACK information for all HARQ-ACK processes of all configured serving cells (e.g., Type-3 HARQ-ACK codebook), the UE transmits the HARQ-ACK information for all HARQ-ACK processes of all configured serving cells. To reduce the size of the Type-3 HARQ-ACK codebook, in the enhanced Type-3 HARQ-ACK codebook, the UE may transmit the HARQ-ACK information for specific HARQ-ACK processes of specific serving cells based on the indication of the DCI. In another example, if the UE receives a DCI format that schedules PDSCH reception, the UE transmits the HARQ-ACK information for the PDSCH reception. In another example, the UE receives SPS PDSCH, and the UE transmits the HARQ-ACK information for the SPS PDSCH reception. In another example, if the UE is configured by higher layer signaling to receive SPS PDSCH, the UE transmits the HARQ-ACK information for the SPS PDSCH reception. Being configured by higher layer signaling to receive SPS PDSCH may be cancelled from transmission by other signaling. In another example, if at least one uplink symbol (e.g., OFDM symbol) in the semi-static frame structure configured by higher layer signaling for the UE overlaps with the symbol of the SPS PDSCH reception, the UE does not receive the SPS PDSCH. In another example, if the UE is configured by higher layer signaling to receive SPS PDSCH according to a predefined rule, the UE transmits the HARQ-ACK information for the SPS PDSCH reception. It should be noted that in the description of the exemplary embodiments of the present disclosure, "A" overlapping with "B" may mean that "A" and "B" overlap at least partially. That is, "A" overlapping with "B" includes the case where "A" and "B" completely overlap. "A" overlapping with "B" may mean that "A" and "B" overlap in the time domain and / or "A" and "B" overlap in the frequency domain.

[0197] In some embodiments, if the HARQ-ACK information transmitted in the same time unit (e.g., uplink time unit) (or multiplexed in the same time unit) does not include any HARQ-ACK information in DCI format, nor includes the reception of dynamically scheduled PDSCH (e.g., PDSCH reception scheduled by DCI format) and / or HARQ-ACK information of DCI, or the HARQ-ACK information transmitted in the same time unit (e.g., uplink time unit) (or multiplexed in the same time unit) only includes the HARQ-ACK information of one or more SPS PDSCH receptions, the UE may generate the HARQ-ACK information (e.g., only the HARQ-ACK information of SPS PDSCH reception) according to the rule of the HARQ-ACK codebook that generates the SPS PDSCH reception. The UE may multiplex the HARQ-ACK information of only SPS PDSCH reception to a specific PUCCH resource. For example, if the UE is configured with the PUCCH list parameter of SPS (e.g., SPS-PUCCH-AN-List), the UE multiplexes the HARQ-ACK information of only SPS PDSCH reception to the PUCCH in the PUCCH list of this SPS. For example, the UE determines a PUCCH resource in the PUCCH list of SPS according to the number of bits of HARQ-ACK. If the UE is not configured with the PUCCH list parameter of SPS, the UE multiplexes the HARQ-ACK information of only SPS PDSCH reception to a specific PUCCH resource for SPS HARQ-ACK (e.g., this PUCCH resource is configured by the n1PUCCH-AN parameter).

[0198] In some embodiments, if the HARQ-ACK information transmitted in the same time unit (e.g., uplink time unit) (or multiplexed in the same time unit) includes HARQ-ACK information in DCI format and / or dynamically scheduled PDSCH reception (e.g., PDSCH reception scheduled by DCI format), the UE may generate the HARQ-ACK information according to the rules for generating the dynamically scheduled PDSCH reception and / or the HARQ-ACK codebook in DCI format. The UE may determine to generate a semi-static HARQ-ACK codebook (e.g., Type-1 HARQ-ACK codebook) or a dynamic HARQ-ACK codebook (e.g., Type-2 HARQ-ACK codebook) according to the HARQ-ACK codebook configuration parameter of the PDSCH reception (e.g., the higher layer parameter pdsch-HARQ-ACK-Codebook). For example, if the UE is configured with the HARQ-ACK codebook configuration parameter (e.g., the higher layer parameter pdsch-HARQ-ACK-Codebook) as semi-static, the UE generates a semi-static HARQ-ACK codebook; if the UE is configured with the HARQ-ACK codebook configuration parameter (e.g., the higher layer parameter pdsch-HARQ-ACK-Codebook) as dynamic, the UE generates a dynamic HARQ-ACK codebook. The dynamic HARQ-ACK codebook may also be an enhanced dynamic HARQ-ACK codebook (e.g., Type-2 HARQ-ACK codebook based on grouping and HARQ-ACK retransmission). The UE may multiplex the HARQ-ACK information onto the PUCCH resource for dynamically scheduled HARQ-ACK, and this PUCCH resource may be configured in the resource set list parameter (e.g., the parameter resourceSetToAddModList). The UE determines a PUCCH resource set in the resource set list according to the number of bits of the HARQ-ACK (e.g., the parameter PUCCH-ResourceSet), and the PUCCH resource may be determined according to the indication of the PRI (PUCCH Resource Indicator) field in the last DCI format to determine a PUCCH in the PUCCH resource set.

[0199] In some embodiments, if the HARQ-ACK information transmitted in the same time unit (e.g., uplink time unit) (or multiplexed in the same time unit) only includes the HARQ-ACK information for SPS PDSCH reception (e.g., PDSCH reception not scheduled by DCI format), the UE may generate the HARQ-ACK codebook according to the rule for generating the HARQ-ACK codebook for SPS PDSCH reception (e.g., the pseudo-code of the codebook for HARQ-ACK of SPS PDSCH reception).

[0200] [Type-1 HARQ-ACK codebook]

[0201] The semi-static HARQ-ACK codebook (e.g., Type-1 HARQ-ACK codebook) may determine the size of the HARQ-ACK codebook and the ordering of HARQ-ACK bits according to semi-statically configured parameters (e.g., parameters configured by higher layer signaling).

[0202] For a serving cell c, an active downlink BWP (bandwidth part), and an active uplink BWP, the UE determines M A,c sets of occasions for the candidate PDSCH reception, where the UE can transmit the corresponding HARQ-ACK information for the candidate PDSCH reception on one of the PUCCHs in uplink slot n U .

[0203] M A,v may be determined based on at least one of the following:

[0204] a) The set of HARQ-ACK slot timing values K1 associated with the active uplink BWP on the primary cell or PUCCH-sScell (PUCCH switching SCell);

[0205] b) The set of row indices of the time domain resource allocation (TDRA) table associated with the active downlink BWP;

[0206] c) where μ DL is the downlink subcarrier spacing (SCS) configuration of the active downlink BWP, and μ UL is the uplink subcarrier spacing configuration of the active uplink BWP.

[0207] d) Semi-static uplink-downlink frame structure configuration, e.g., parameter tdd-UL-DL-ConfigurationCommon and parameter tdd-UL-DL-ConfigurationDedicated.

[0208] e) Downlink slot offset parameter of serving cell c (e.g., higher layer parameter ) and its corresponding slot offset SCS (e.g., higher layer parameter μ offset,DL,c ), or downlink slot offset parameter of the primary cell (e.g., higher layer parameter ) and its corresponding slot offset SCS (e.g., higher layer parameter μ offset,UL ).

[0209] The set of parameter K1 is used to determine candidate uplink slots, and then candidate downlink slots are determined according to the candidate uplink slots. The candidate downlink slots satisfy at least one of the following conditions: (i) If the time unit of PUCCH is a sub-slot, at least one end position of the received candidate PDSCH in the candidate downlink slots overlaps with the candidate uplink slots in the time domain; or (ii), if the time unit of PUCCH is a slot, the end position of the candidate downlink slots overlaps with the candidate uplink slots in the time domain. It should be noted that in the description of the exemplary embodiments of the present disclosure, the start symbol and the start position can be used interchangeably, and the end symbol and the end position can be used interchangeably. In some embodiments, the start symbol can be replaced with the end symbol, and / or the end symbol can be replaced with the start symbol.

[0210] The number of PDSCH receptions for which HARQ-ACK needs to be fed back in a candidate downlink slot can be determined by the maximum value of the number of non-overlapping valid candidate PDSCH receptions (e.g., valid candidate PDSCH receptions can be candidate PDSCH receptions that do not overlap with semi-statically configured uplink symbols) in the downlink slot. The time-domain resources occupied by the candidate PDSCH receptions can be determined by (i) configuring a time-domain resource allocation table by higher-layer signaling (which may also be referred to as a table associated with time-domain resource allocation in the description of some exemplary embodiments of the present disclosure) and (ii) dynamically indicating a certain row in the time-domain resource allocation table by DCI. Each row in the time-domain resource allocation table can define information related to time-domain resource allocation. For example, for the time-domain resource allocation table, the indexed row defines the timing value (e.g., time unit (e.g., slot) offset (e.g., K0)) between the PDCCH and the PDSCH, the start and length indicator (SLIV), or directly defines the start symbol and the allocated length. For example, for the first row of the time-domain resource allocation table, the starting OFDM symbol is 0 and the OFDM symbol length is 4; for the second row of the time-domain resource allocation table, the starting OFDM symbol is 4 and the OFDM symbol length is 4; for the third row of the time-domain resource allocation table, the starting OFDM symbol is 7 and the OFDM symbol length is 4. The DCI scheduling the PDSCH can indicate any row in the time-domain resource allocation table. When all the OFDM symbols in the downlink slot are downlink symbols, the maximum value of the number of non-overlapping valid PDSCHs in the downlink slot is 2. At this time, the type-1 HARQ-ACK codebook may need to feed back HARQ-ACK information for 2 PDSCHs in this downlink slot of this serving cell.

[0211] Figure 9A and Figure 9B shows an example of a time-domain resource allocation (TDRA) table. Specifically, Figure 9A shows a time-domain resource allocation table for scheduling one PDSCH per row, Figure 9B shows a time-domain resource allocation table for scheduling multiple PDSCHs per row. Referring to Figure 9A , each row corresponds to a set of {K0, mapping type, SLIV}, and the set of {K0, mapping type, SLIV} includes a timing parameter K0 value, a mapping type, and an SLIV. Referring to Figure 9B , different from Figure 9A , each row corresponds to multiple sets of {K0, mapping type, SLIV}.

[0212] [Type-2 HARQ-ACK codebook]

[0213] In some embodiments, a dynamic HARQ-ACK codebook (e.g., a type-2 HARQ-ACK codebook) and / or an enhanced dynamic HARQ-ACK codebook (e.g., a type-2 HARQ-ACK based on packet and HARQ-ACK retransmission) may determine the size and sorting of the HARQ-ACK codebook according to an allocation index. For example, the allocation index may be DAI (Downlink Assignment Index). In the following embodiments, DAI is taken as an example of the allocation index for illustration. However, the embodiments of the present disclosure are not limited thereto, and any other suitable allocation index may be adopted. It should be noted that the method for the dynamic HARQ-ACK codebook in the present disclosure may also be used for the enhanced dynamic HARQ-ACK codebook.

[0214] In some embodiments, the DAI includes at least one of a first DAI and a second DAI.

[0215] In some examples, the first DAI may be C-DAI (Counter-DAI), and the first DAI may be the cumulative count of downlink assignment indices. The value of the first DAI field in the DCI format is the cumulative count up to the current serving cell and up to the current time unit {serving cell, PDCCH monitoring occasion (MO)}-pair, where the time unit may be the time unit of PDCCH reception, e.g., the PDCCH monitoring occasion. The {serving cell, PDCCH monitoring occasion}-pair may include PDSCH reception scheduled by the DCI format and / or a DCI format with corresponding HARQ-ACK information bits without scheduling PDSCH reception. The first DAI may be included in the downlink DCI format. The HARQ-ACK information of the PDSCH reception scheduled by the DCI format and / or the DCI format without scheduling PDSCH reception is sent in the same time unit (e.g., on the same PUCCH in the same time unit). The second DAI may be T-DAI (Total-DAI). The second DAI may be the total count of downlink assignment indices. The value of the second DAI field in the DCI format is the total count up to the current time unit {serving cell, PDCCH monitoring occasion}-pair. The second DAI may be included in the downlink DCI format and / or the uplink DCI format. The second DAI included in the uplink DCI format is also referred to as UL DAI.

[0216] In some embodiments, the first DAI may be sorted in the following order:

[0217] - First, in ascending order of the serving cell (e.g., the scheduled serving cell) index

[0218] - Second, in ascending order of the PDCCH MO index.

[0219] In some embodiments, the first DAI may also be sorted in the following order. For example, if the UE reports the ability to support receiving more than one PDSCH on one PDCCH MO scheduling a serving cell (e.g., PDSCH reception scheduled by more than one PDCCH), the first DAI may be sorted in the following order:

[0220] - First, in ascending order of the start time of PDSCH reception (e.g., for the same

[0221] {serving cell, PDCCH monitoring occasion}-pair of PDCCH receptions)

[0222] - Second, in ascending order of the serving cell (e.g., the scheduled serving cell) index

[0223] - Third, in ascending order of the PDCCH MO index.

[0224] In some examples, the first DAI may indicate the cumulative count of at least one of the DCI indicating scheduled PDSCH reception, or the DCI indicating SPS PDSCH release (deactivation), or the DCI indicating secondary cell dormancy. For example, the cumulative count may be the cumulative count up to the current serving cell and / or the current time unit. The C-DAI may also indicate the cumulative number of {serving cell, time unit} pairs scheduled by the PDCCH up to the current time unit within a time window (which may also include the number of PDCCHs (e.g., PDCCH indicating SPS release, and / or PDCCH indicating secondary cell dormancy)); or the cumulative number of PDCCHs up to the current time unit; or the cumulative number of PDSCH transmissions up to the current time unit; or the cumulative number of {serving cell, time unit} pairs with PDSCH transmissions (e.g., scheduled by the PDCCH) and / or PDCCHs (e.g., PDCCH indicating SPS release, and / or PDCCH indicating secondary cell dormancy) up to the current serving cell and / or the current time unit; or the cumulative number of PDSCHs and / or PDCCHs (e.g., PDCCH indicating SPS release, and / or PDCCH indicating secondary cell dormancy) with corresponding PDCCHs scheduled by the base station up to the current serving cell and / or the current time unit; or the cumulative number of PDSCHs scheduled by the base station up to the current serving cell and / or the current time unit (the PDSCHs being PDSCHs with corresponding PDCCHs); or the cumulative number of time units with PDSCH transmissions scheduled by the base station up to the current serving cell and / or the current time unit (the PDSCHs being PDSCHs with corresponding PDCCHs). The ordering of each bit in the HARQ-ACK codebook corresponding to at least one of PDSCH reception, the DCI indicating SPS PDSCH release (deactivation), or the DCI indicating secondary cell dormancy can be determined by receiving the time including the first DAI and the first DAI information.

[0225] In some examples, the second DAI may indicate the total count of at least one of all PDSCH receptions, the DCI indicating SPS PDSCH release (deactivation), or the DCI indicating secondary cell dormancy. For example, the total count may be the total count of all serving cells up to the current time unit. For example, T-DAI may refer to: within a time window, the total number of {serving cell, time unit} pairs scheduled by PDCCH up to the current time unit (which may also include the number of PDCCHs for indicating SPS release); or the total number of PDSCH transmissions up to the current time unit; or up to the current serving cell and / or the current time unit, the total number of {serving cell, time unit} pairs where there is a PDSCH transmission related to a PDCCH (e.g., scheduled by PDCCH) and / or there is a PDCCH (e.g., a PDCCH indicating SPS release, and / or a PDCCH indicating secondary cell dormancy); or up to the current serving cell and / or the current time unit, the total number of PDSCHs and / or PDCCHs (e.g., a PDCCH indicating SPS release, and / or a PDCCH indicating secondary cell dormancy) for which there is a corresponding PDCCH that the base station has scheduled; or up to the current serving cell and / or the current time unit, the total number of PDSCHs (where the PDSCH is a PDSCH with a corresponding PDCCH) that the base station has scheduled; or up to the current serving cell and / or the current time unit, the total number of time units with PDSCH transmissions (e.g., the PDSCH is a PDSCH with a corresponding PDCCH) that the base station has scheduled.

[0226] In the following example, the first DAI is C-DAI and the second DAI is T-DAI (but not limited to) as an example for illustration.

[0227] Table 1 and Table 2 show the correspondence between the DAI field and V T-DAI,m , V C-DAI,c,m or The number of bits of C-DAI and T-DAI is limited.

[0228] For example, when C-DAI or T-DAI is represented by 2 bits, the value of C-DAI or T-DAI in the DCI can be determined by the formula in Table 1. V T-DAI,m or is the value of T-DAI in the DCI format received at the PDCCH monitoring occasion (Monitoring Occasion, MO) m, and V C-DAI,c,m is the value of C-DAI in the DCI format for the serving cell c received at the PDCCH monitoring occasion m. V T-DAI,m and V C-DAI,c,mBoth are related to the number of bits in the DAI field in the DCI format. MSB stands for Most Significant Bit, and LSB stands for Least Significant Bit.

[0229] [Table 1]

[0230]

[0231] For example, if C-DAI or T-DAI is 1, 5, or 9, as shown in Table 1, it is indicated by "00" in the DAI field, and V T-DAI,m or V C-DAI,c,m is represented as "1" through the formula in Table 1. Y can represent the value of DAI corresponding to the number of DCI formats actually sent by the base station (the value of DAI before conversion through the formula in the table).

[0232] For example, in the case where C-DAI or T-DAI in the DCI format is 1 bit, a value greater than 2 can be obtained through the formula in Table 2.

[0233] [Table 2]

[0234]

[0235] In some embodiments, the UE can generate the HARQ-ACK codebook in the PUCCH according to Pseudocode 1. For example, if the UE transmits HARQ-ACK information on a PUCCH (e.g., any PUCCH format) in slot n, the UE determines the HARQ-ACK information bits, where O ACK is the total number of HARQ-ACK information bits.

[0236] [Pseudocode 1]

[0237]

[0238]

[0239]

[0240] In some embodiments, for the HARQ-ACK codebook on the PUSCH, after the UE completes the c and m loops for generating the HARQ-ACK codebook in Pseudocode 1, set where is the UL DAI, and its value can be determined according to Table 1 or Table 2.

[0241] [HARQ Feedback Method]

[0242] In some embodiments, it may be configured by higher layer parameters or dynamically indicated by DCI whether to feedback HARQ-ACK information. The way of feedbacking (or reporting) HARQ-ACK information (HARQ-ACK feedback way or HARQ-ACK reporting way) can be at least one of the following ways.

[0243] - HARQ-ACK feedback way 1: Send ACK or NACK (ACK / NACK). For example, for a PDSCH reception, if the UE correctly decodes the corresponding transport block (TB), the UE sends ACK; and / or, if the UE does not correctly decode the corresponding transport block, the UE sends NACK. For example, the HARQ-ACK information bits of the HARQ-ACK information provided according to HARQ-ACK feedback way 1 are ACK value or NACK value.

[0244] - HARQ-ACK feedback way 2: Only send NACK (NACK-only). For example, for a PDSCH reception, if the UE correctly decodes the corresponding transport block, the UE does not send HARQ-ACK information; and / or, if the UE does not correctly decode the corresponding transport block, the UE sends NACK. For example, at least one HARQ-ACK information bit of the HARQ-ACK information provided according to HARQ-ACK feedback way 2 is NACK value. For example, in HARQ-

[0245] ACK feedback way 2, the UE does not send a PUCCH that only includes HARQ-ACK

[0246] information with ACK value.

[0247] For a PDSCH reception of a HARQ process, if the UE is configured not to feedback HARQ-ACK information, the HARQ-ACK information of this PDSCH reception is not included in the HARQ-ACK codebook.

[0248] [Channel conflict]

[0249] In some embodiments, the conflict between PUSCH and other physical channels can be at least one of the following:

[0250] - The PUSCH overlaps with PUCCH and / or PDSCH and / or PDCCH on the same serving cell in the time domain.

[0251] - Without being configured for simultaneous transmission of PUSCH, the PUSCH overlaps with other PUSCH on the same serving cell in the time domain.

[0252] - In the case of being configured for PUSCH simultaneous transmission, one PUSCH overlaps in time domain with another PUSCH having the same control resource set (CORESET) pool index parameter (e.g., coresetPoolIndex) value on the same serving cell.

[0253] - The PUSCH overlaps in time domain with the PUCCH. For example, the PUSCH overlaps in time domain with the PUCCH on different serving cells, and / or the serving cell does not support PUSCH and PUCCH simultaneous transmission.

[0254] In some embodiments, the conflict between the PDSCH and other physical channels may be at least one of the following:

[0255] - The PDSCH overlaps in time domain with other PUSCH and / or PUCCH on the same serving cell.

[0256] - In the case of not being configured for PDSCH simultaneous reception (e.g., the UE is not configured with different CORESET pool index parameters (e.g., coresetPoolIndex) values), the PDSCH overlaps in time domain with other PDSCH on the same serving cell.

[0257] - In the case of being configured for PDSCH simultaneous transmission (e.g., the UE is configured with PDCCH configuration parameters (e.g., PDCCH-Config) including different CORESET pool index parameters (e.g., coresetPoolIndex) values in the CORESET parameters (e.g., ControlResourceSet)), one PDSCH overlaps in time domain with another PDSCH having the same CORESET pool index parameter (e.g., coresetPoolIndex) value on the same serving cell.

[0258] - The PDSCH overlaps with the PDCCH on the same serving cell in both time domain and frequency domain.

[0259] In some embodiments, the conflict between the PUCCH and other physical channels may be at least one of the following:

[0260] - The PUCCH overlaps in time domain with other PUCCH and / or PUSCH.

[0261] - The PUCCH overlaps in time domain with other PDSCH on the same serving cell.

[0262] In some embodiments, the conflict between the PDCCH and other physical channels may be at least one of the following:

[0263] - The PDCCH overlaps in time domain with other PUSCH and / or PUCCH on the same serving cell.

[0264] - The PDCCH overlaps with other PDSCH on the same serving cell in both time domain and frequency domain.

[0265] In the description of the exemplary embodiments of the present disclosure, a "set of overlapping channels" may be understood as each channel in the set of overlapping channels overlapping (or conflicting) with at least one of the channels other than this channel in the set. The channel may include one or more PUCCH and / or one or more PUSCH. For example, a "set of overlapping channels" may include a "set of overlapping PUCCH and / or PUSCH". As a specific example, when the first PUCCH overlaps with at least one of the second PUCCH and the third PUCCH, the second PUCCH overlaps with at least one of the first PUCCH and the third PUCCH, and the third PUCCH overlaps with at least one of the first PUCCH and the second PUCCH, the first PUCCH, the second PUCCH, and the third PUCCH form a set of overlapping channels (PUCCH). For example, the first PUCCH overlaps with both the second PUCCH and the third PUCCH, and the second PUCCH and the third PUCCH do not overlap.

[0266] In the description of the exemplary embodiments of the present disclosure, "resolving overlapping channels" may be understood as resolving the conflicts of overlapping channels. For example, when a PUCCH overlaps with a PUSCH, resolving the overlap or conflict may include multiplexing the UCI in the PUCCH into the PUSCH, or may include transmitting a PUCCH or PUSCH with a higher priority. As another example, when a PUCCH overlaps with one or another PUCCH, resolving the overlap or conflict may include multiplexing the UCI into one of the PUCCHs, or may include transmitting a PUCCH with a higher priority. As another example, when two PUSCH on the same serving cell overlap, resolving the overlap or conflict may include transmitting the PUSCH with a higher priority among the two PUSCHs. "Resolving overlapping channels", "resolving the overlap between channels", "determining the overlap between channels", and "determining overlapping channels" may be used interchangeably.

[0267] It should be noted that, unless otherwise clearly indicated by the context, all or one or more of the methods, steps or operations described in the embodiments of the present disclosure can be configured and / or dynamically signaled by protocol specifications and / or higher layer signaling. The dynamic signaling can be PDCCH and / or DCI and / or DCI format. For example, for SPS PDSCH and / or CG PUSCH, it can be dynamically indicated in its activation DCI / DCI format / PDCCH. All or one or more of the described methods, steps and operations can be optional. For example, if a certain parameter (e.g., parameter X) is configured, the UE performs a certain manner (e.g., manner A), otherwise (if the parameter is not configured, e.g., parameter X), the UE performs another manner (e.g., manner B). If there is no special indication, the parameters in the embodiments of the present disclosure can be higher layer parameters. For example, the higher layer parameters can be parameters configured or indicated by higher layer signaling (e.g., RRC signaling).

[0268] It should be noted that, in the description of the exemplary embodiments of the present disclosure, the PCell (primary cell) or PSCell (primary and secondary cell) can be used interchangeably with the cell having PUCCH. The serving cell can be used interchangeably with the cell.

[0269] It should be noted that, in the description of the exemplary embodiments of the present disclosure, the method for the downlink can also be applicable to the uplink, and the method for the uplink can also be applicable to the downlink. For example, PDSCH can be replaced with PUSCH, SPS PDSCH with CG PUSCH, and downlink symbols with uplink symbols, so that the method for the downlink can be applicable to the uplink.

[0270] It should be noted that, in the description of the exemplary embodiments of the present disclosure, the method applicable to multiple PDSCH / PUSCH scheduling can also be applicable to PDSCH / PUSCH repeated transmission. For example, one PDSCH / PUSCH in multiple PDSCH / PUSCH can be replaced with one repeated transmission in PDSCH / PUSCH multiple repeated transmissions.

[0271] It should be noted that in the method of the present disclosure, in the description of the exemplary embodiments of the present disclosure, being configured and / or indicated for retransmission can be understood as the number of retransmissions being greater than 1. For example, "PUCCH configured and / or indicated for retransmission" can be replaced by "PUCCH retransmitted on more than one time slot / sub-time slot". Not being configured and / or indicated for retransmission can be understood as the number of retransmissions being equal to 1. For example, "PUCCH not configured and / or indicated for retransmission" can be replaced by "PUCCH transmission with the number of retransmissions being 1". For example, the UE can be configured with parameters related to the number of PUCCH retransmissions. When this parameter is greater than 1, it can mean that the UE is configured for PUCCH retransmission, and the UE can retransmit the PUCCH on a number of time units (e.g., time slots); when this parameter is equal to 1, it can mean that the UE is not configured for PUCCH retransmission. For example, the retransmitted PUCCH can only contain one type of UCI. If the PUCCH is configured for retransmission, in the description of the exemplary embodiments of the present disclosure, one retransmission among the multiple PUCCH retransmissions can be regarded as one PUCCH (or PUCCH resource), or all the PUCCH retransmissions can be regarded as one PUCCH (or PUCCH resource), or a specific retransmission among the multiple PUCCH retransmissions can be regarded as one PUCCH (or PUCCH resource).

[0272] It should be noted that in the description of the exemplary embodiments of the present disclosure, one PDCCH and / or DCI and / or DCI format scheduling multiple PDSCH / PUSCH can be multiple PDSCH / PUSCH in the same serving cell and / or multiple PDSCH / PUSCH in different serving cells.

[0273] It should be noted that in the exemplary embodiments of the present disclosure, multiple manners / methods can be combined in any order. In a combination, one manner / method can be executed once or multiple times, or one manner / method can not be executed. In addition, in the exemplary embodiments of the present disclosure, at least one step / operation in one manner / method among multiple manners / methods can be combined with one or more steps / operations in one or more other manners / methods to form a new embodiment. The steps / operations in the combination can be executed once or multiple times. When executing one manner / method or a combination of manners / methods, one or more steps / operations of the manner / method or the combination of manners / methods can be omitted, or other associated steps / operations (e.g., one or more steps / operations in other associated manners / methods) can be additionally executed.

[0274] It should be noted that multiple steps in the methods of the present disclosure can be implemented in any order.

"The time interval between the first physical channel and the second physical channel is less than a predefined time", "the first physical channel is earlier than the second physical channel by less than a predefined time", and "the first physical channel is earlier than the second physical channel within a predefined time" can be used interchangeably; "the time interval between the first physical channel and the second physical channel is greater than a predefined time", "the first physical channel is earlier than the second physical channel by greater than a predefined time", and "the first physical channel is earlier than the second physical channel outside a predefined time" can be used interchangeably. Alternatively, the time interval (or time unit interval) between the time unit where the first physical channel is located and the time unit where the second channel is located. The time unit where the physical channel is located can be understood as the time unit overlapping with the end position (or end symbol) of the physical channel or the time unit overlapping with the start position (or start symbol) of the physical channel.

[0280] It should be noted that in the description of the exemplary embodiments of the present disclosure, "when a predefined condition is met, execute a predefined method (or step)" and "when the predefined condition is not met, do not execute the predefined method (or step)" can be used interchangeably.

[0291] It should be noted that in the description of the exemplary embodiments of the present disclosure, the behavior of a UE (or base station) and the condition of the corresponding UE (or base station) behavior can be used interchangeably. For example, "UE receives (or is configured with) first information (or parameter)" and "if the UE is configured with first information (or parameter)" can be used interchangeably.

[0292] It should be noted that in the description of the exemplary embodiments of the present disclosure, receiving the information carried by a DCI format can be understood as detecting a DCI format that carries the information.

[0293] It should be noted that in the exemplary embodiments of the present disclosure, the terms "index", "identification", "identifier", and "number" can be used interchangeably.

[0297] It should be noted that in the description of the exemplary embodiments of the present disclosure, a beam can be understood as a Transmission Configuration Indicator (TCI) state / reference signal / channel / spatial relationship; or a TCI state ID / reference signal ID / channel ID / spatial relationship ID; or a spatial domain filter associated with the TCI state / reference signal / channel / spatial relationship; or a spatial domain filter associated with the TCI state ID / reference signal ID / channel ID / spatial relationship ID. In the exemplary embodiments of the present disclosure, the following descriptions can be used interchangeably:

[0298] - beam;

[0299] - spatial filter;

[0300] - spatial domain filter;

[0301] - spatial domain transmission filter;

[0302] - spatial setting;

[0303] - Quasi-Co-Location (QCL) assumption;

[0311] In some embodiments, the RS can be the RS corresponding to a beam. For example, the RS can be CSI-RS or SSB.

[0312] In some examples, the UE can be configured or provided with a SRS resource set index parameter (e.g., SRS_resource_set_index) having two different values (e.g., value 0 and value 1). The first SRS resource set (SRS resource set index parameter value equal to 0) can correspond to a CORESET pool index parameter value equal to 0, and the other SRS resource set (SRS resource set index parameter value equal to 1) can correspond to a CORESET pool index parameter value equal to 1.

[0313] In the embodiments of the present disclosure, a "panel" can refer to a set of antenna ports or an antenna group. The uplink transmission configuration indicator (TCI) of each antenna panel can be used to indicate the beam for that antenna panel, and the beam can be the beam associated with the indicated reference signal ID. The SRS set ID can be used to indicate the antenna panel ID, where each antenna panel is associated with an SRS set.

[0314] In operation S710, the UE can receive first information from the base station, where the first information can be downlink control signaling. For example, the first information can be configuration information carried by higher layer signaling. The first information can be used to indicate configuration information related to the second information and / or the fourth information, where the second information can indicate (or notify) the UE to send (e.g., the UE is to send; the UE intends to send; the UE needs to send; the UE initiates sending; or is to send due to various events or reasons) the fourth information, or the second information can indicate whether the UE sends the fourth information; the fourth information can include a report (or transmission) of beam-related information. The second information can be a new UCI type different from the existing UCI types. For example, the second information can be a UCI type different from SR, LRR, HARQ-ACK, CSI. Or the second information can be a specific SR. In some embodiments, the second information can include positive second information or negative second information. For example, the positive second information can indicate that the UE sends (e.g., the UE is to send; the UE intends to send; the UE needs to send; the UE initiates sending; or is to send due to various events or reasons) the fourth information. For example, the negative second information can indicate that the UE does not send the fourth information.

[0315] In some embodiments, the fourth information may further include at least one of uplink data, HARQ-ACK information, CSI report, or other UCI information.

[0316] In some embodiments, the beam-related information may be at least one of the following:

[0317] - CSI report

[0318] - Beam management information

[0319] - Beam measurement information

[0320] - BFR (beam failure recovery)

[0321] As some examples, the beam management information may refer to information related to beam management.

[0322] As some examples, the beam measurement information may refer to information related to beam measurement.

[0323] As some examples, BFR may refer to information related to the BFR process.

[0324] It should be noted that the "CSI report", "beam management information", "beam measurement information", and "BFR" described above are only examples of beam-related information. The exemplary embodiments of the present disclosure are equally applicable to other beam-related information.

[0325] It should be noted that although the "CSI report", "beam management information", "beam measurement information", and "BFR" are described separately, it will be understood that one of them may be included in another as the fourth information. For example, at least one of the "beam management information", "beam measurement information", and "BFR" may be included in the CSI report as the fourth information. Therefore, in the exemplary embodiments of the present disclosure, the CSI report may also refer to a CSI report including at least one of beam management information, beam measurement information, or BFR.

[0326] In the following exemplary embodiments of the present disclosure, for the sake of explanation, the CSI report may be used as an example of beam-related information for description. However, it will be understood that the "CSI report" may be replaced with other beam-related information.

[0327] In some embodiments, the beam-related information may be beam-related information triggered by the UE. For example, the beam-related information may be a CSI report triggered by the UE.

[0328] In some embodiments, the fourth information may include reporting (or transmitting) of one or more beam-related information. For example, the fourth information may include reporting (or transmitting) of one or more beam-related information in a time unit and / or in a PUCCH or PUSCH.

[0329] In operation S730, the UE transmits the second information. For example, the UE may transmit the second information in an uplink time unit.

[0330] Optionally, in operation S710, the UE may also receive third information, where the third information may indicate the quantity (or number of types, or number of configurations) M of the fourth information (e.g., the quantity (or type) M of the fourth information in a time unit), or the third information may indicate the quantity (or number of types, or number of configurations) M of the fourth information that the UE transmits simultaneously (e.g., at the same moment or time unit). Here, M may be a non-negative integer or a positive integer. For example, M may be 1, 2, 3, or 4. If the UE is not configured with the third information, in a time unit, the UE may report (or transmit) one beam-related information. The one beam-related information may be beam measurement information of a beam set including the beam. And / or, the one beam-related information may be beam measurement information of a beam set associated with the beam. The UE may report the maximum value of M through UE capability. For example, the maximum value of M may be 1, 2, or 4.

[0331] Optionally, in operation S710, the UE may also receive thirteenth information, where the thirteenth information may be configuration information related to one or more second information. For example, the thirteenth information may be a list of configuration information related to the second information, and one element in the list corresponds to one configuration information related to the second information. The number of elements in the list may be M. The elements in the thirteenth information and the elements in the fifth information may correspond one by one. The number of elements in the thirteenth information may also be M', where M' may be a non-negative integer or a positive integer. For example, M' may be 1, 2, 3, or 4, etc. One or more elements in the thirteenth information may correspond to one element in the fifth information. One element in the thirteenth information may correspond to one or more elements in the fifth information. For example, one or more elements (e.g., element indices) in the thirteenth information associated with each element may be configured in the fifth information. Or, one or more elements (e.g., element indices) in the fifth information associated with each element may be configured in the thirteenth information.

[0332] Optionally, in operation S710, the UE may further receive fifth information, where the fifth information may be configuration information related to one or more fourth information. For example, the fifth information may be a list of configuration information related to the fourth information, and one element in the list corresponds to one configuration information related to the fourth information. The number of elements in the list may be M.

[0333] In some embodiments, the UE may be configured with N pieces of sixth information, and each piece of sixth information may correspond to configuration information of one piece of second information and / or fourth information. Alternatively, the UE may be configured with a list of sixth information. Here, N may be a positive integer. For example, N may be 1, 2, 3, or 4. The maximum value of N may be 1, 2, or 4. The UE may report the maximum value of N through the UE capability. In some embodiments, N may be equal to M. The sixth information and the second information and / or the fourth information may correspond one by one. In some embodiments, N may be less than M. One piece of sixth information may correspond to configuration information of one or more pieces of second information and / or fourth information. Optionally, the first information may include the sixth information.

[0334] In some embodiments, the sixth information may include at least one of the following:

[0335] - The first PUCCH resource, for example, the first PUCCH resource index. For example, the first PUCCH resource index may be the parameter PUCCH-ResourceId. The first PUCCH resource may be the PUCCH resource carrying the second information. Alternatively, the first PUCCH resource may be the PUCCH resource carrying the second information and the fourth information.

[0336] - The first BWP index. The first BWP index may be the BWP index where the first PUCCH resource is located (or, corresponding to).

[0337] - The second PUCCH resource, for example, the second PUCCH resource index. For example, the second PUCCH resource index may be the parameter PUCCH-ResourceId. The second PUCCH resource may be the PUCCH resource carrying the fourth information.

Alternatively, the PUSCH resource can be a PUSCH resource carrying the second information and the fourth information. The PUSCH resource can be a CG PUSCH resource. For example, a CG PUSCH configuration index parameter can be configured. For example, the parameter ConfiguredGrantConfigIndex.

[0342] - Index of the fourth BWP. The index of the fourth BWP is the BWP index where the PUSCH resource is located (or, corresponding to). Alternatively, the fourth BWP index is the BWP index on the serving cell where the PUSCH resource is located (or, corresponding to).

[0349] - CSI report configuration index corresponding to the fourth information. For example, the parameter CSI-ReportConfigId.

[0350] - The first timer or the first time interval. For example, the first timer or the first time interval can be the time interval (or the minimum time interval) between two transmissions of the second information (e.g., two adjacent transmissions of the second information). For example, the first timer can be a timer that prohibits the transmission of the second information. For example, when the first timer is running, the second information is not transmitted; and / or when the first timer expires or is not running, the second information can be transmitted.

[0351] In some embodiments, a sixth information can correspond to the configuration information of a pair or a set of a second information and a fourth information. Wherein, the pair of the second information and the fourth information includes an associated second information and a fourth information. The set of the second information and the fourth information includes one or more associated second information and a fourth information, or an associated second information and one or more fourth information.

[0352] It should be noted that the first RS can be the RS corresponding to the current beam (or TCI), the second RS is the RS corresponding to the candidate beam (or TCI), or the second RS is the RS corresponding to the current beam (or TCI) and the candidate beam (or TCI).

[0353] In some embodiments, for a first RS (or a first RS index), the sixth information can configure one or more second RSs (or second RS indexes). For example, the sixth information can configure a set of second RSs, and the set of second RSs includes one or more second RSs. The one or more second RSs can include the first RS. For example, the first (or the last) RS in the set of second RSs is the first RS.

[0354] In some embodiments, a list of sets of second RSs can be configured, and each element in the list of sets of second RSs is a set of second RSs.

[0355] In some embodiments, a list of first RSs and a list of sets of second RSs can be configured, wherein the elements in the list of first RSs are first RSs. The elements in the list of first RSs and the list of sets of second RSs correspond one by one. For example, the set of second RSs corresponding to a first RS in the list of first RSs is the set of second RSs with the same index in the list of sets of second RSs.

[0356] In some embodiments, the UE may be configured with ninth information, and the ninth information includes configuration information related to tenth information. The tenth information is used to indicate the wake-up of one or more cells, and / or a wake-up request (e.g., an uplink wake-up request), and / or to request a first predefined downlink channel (e.g., an on-demand SSB / SIB1 / PDCCH / PSS (primary synchronization signal) / SSS (second synchronization signal)). In some cases, the UE may send the tenth information. The configuration method of the sixth information in the embodiments of the present disclosure may be reused to configure the ninth information, and / or the method of configuring the configuration information related to the second information and / or the fourth information may be reused to configure the configuration information related to the tenth information, and / or the transmission of the second information and / or the fourth information may be reused to send the tenth information. For example, in the embodiments of the present disclosure, "sixth information" may be replaced with "ninth information", and / or "second information" in the embodiments of the present disclosure may be replaced with "tenth information", and / or "fourth information" in the embodiments of the present disclosure may be replaced with "tenth information", and / or "second information and / or fourth information" in the embodiments of the present disclosure may be replaced with "tenth information". The tenth information may be a type of UCI different from SR, LRR, HARQ-ACK, CSI. Alternatively, the tenth information may be a specific SR. In an exemplary embodiment of the present disclosure, the first predefined downlink channel may include at least one of the following: on-demand SSB, SIB1, PDCCH, PSS, or SSS.

[0357] In some embodiments, the tenth information may include positive tenth information or negative tenth information. For example, positive tenth information may indicate the wake-up of one or more cells, and / or a wake-up request (e.g., an uplink wake-up request), and / or to request a first predefined downlink channel (e.g., an on-demand SSB / SIB1 / PDCCH). For example, negative tenth information may indicate the non-wake-up of one or more cells, and / or not to request a wake-up (e.g., not to request an uplink wake-up), and / or not to request a first predefined downlink channel (e.g., an on-demand SSB / SIB1 / PDCCH). That is, negative tenth information may indicate that the UE does not request the wake-up of one or more cells, and / or does not request a first predefined downlink channel.

[0358] In some embodiments, the ninth information may include at least one of the following:

[0359] - The third PUCCH resource, for example, the third PUCCH resource index. For example, the third PUCCH resource index may be the parameter PUCCH-ResourceId. The third PUCCH resource may be the PUCCH resource carrying the tenth information.

[0360] - The fifth BWP index. The fifth BWP index may be the BWP index where (or corresponding to) the third PUCCH resource is located.

[0361] - The SR information corresponding to the tenth information. For example, the index of the SR (for example, the parameter schedulingRequestID).

[0362] - The SR resource information corresponding to the tenth information. For example, the index of the SR resource (for example, the parameter schedulingRequestResourceId).

[0363] - The second timer or the second time interval. For example, the second timer or the second time interval may be the time interval (or the minimum time interval) between two transmissions of the tenth information (for example, two adjacent transmissions of the tenth information). For example, the second timer may be the timer for prohibiting the transmission of the tenth information. For example, when the second timer is running, the tenth information is not transmitted.

[0364] - The PRACH information corresponding to the tenth information.

[0365] - The message A (MSG A) information corresponding to the tenth information (for example, for random access).

[0366] - The information of the first predefined downlink channel corresponding to the tenth information. For example, the SSB or SIB1 corresponding to the tenth information.

[0367] The serving cell information corresponding to the tenth information. For example, the index of the serving cell (for example, the physical cell ID (PCI); or for example, ServCellIndex).

[0368] In some embodiments, a parameter may be configured in a CG PUSCH configuration parameter (e.g., ConfiguredGrantConfig), which is used to indicate whether the CG PUSCH is used for the second information and / or the fourth information, and / or which is used to indicate the corresponding second information and / or fourth information configuration (e.g., the second information and / or fourth information configuration number) and / or which is used to indicate the corresponding first PUCCH resource. This can clarify the PUSCH resource for transmitting the second information and / or the fourth information and improve the reliability of the uplink transmission. It should be noted that the "CG PUSCH configuration parameter (e.g., ConfiguredGrantConfig)" in this method can be replaced with the "PUCCH resource parameter (e.g., PUCCH-Resource)".

[0369] In some embodiments, a first parameter list may be configured, and the first parameter list is used to configure the PUCCH resource corresponding to the second information. For example, the elements in the first parameter list are PUCCH resource indexes (e.g., pucch-ResourceId), and the index of each element in the first parameter list corresponds to the second information configuration with the same index. For another example, an element in the first parameter list includes a PUCCH resource index (e.g., pucch-ResourceId) and a second information configuration index. The second information configuration configured by this element is carried by the PUCCH resource configured by this element. The first parameter list may be configured in a PUCCH configuration parameter (e.g., the parameter PUCCH-Config). This can clarify the PUCCH resource for transmitting the second information and improve the reliability of the uplink transmission. It should be noted that the first PUCCH resource index in the embodiments of the present disclosure may be the index corresponding to the element (or resource) in the first parameter list. It should be noted that the "second information" can be replaced with the "tenth information".

[0370] In some embodiments, a second parameter list may be configured, and the second parameter list is used to configure PUCCH resources corresponding to the second information and / or the fourth information. For example, an element in the second parameter list is a PUCCH resource index (e.g., pucch-ResourceId), and the index of each element in the second parameter list corresponds to the configuration of the second information and / or the fourth information with the same index. For another example, an element in the second parameter list includes a PUCCH resource index (e.g., pucch-ResourceId) and a configuration index of the second information and / or the fourth information. The configuration of the second information and / or the fourth information configured by the one element is carried by the PUCCH resource configured by the element. The second parameter list may be configured in PUCCH configuration parameters (e.g., parameter PUCCH-Config). This can clarify the PUCCH resources for transmitting the second information and / or the fourth information and improve the reliability of uplink transmission. It should be noted that the second PUCCH resource index in the embodiments of the present disclosure may be the index corresponding to an element (or resource) in the second parameter list.

[0371] In some embodiments, a third parameter list may be configured, and the third parameter list is used to configure PUSCH configurations corresponding to the second information and / or the fourth information, for example, CG PUSCH configurations. For example, an element in the third parameter list is a CG PUSCH configuration index (e.g., ConfiguredGrantConfigIndex) and / or a serving cell index, and the index of each element in the third parameter list corresponds to the configuration of the second information and / or the fourth information with the same index. For another example, an element in the third parameter list includes a CG PUSCH configuration index (e.g., ConfiguredGrantConfigIndex) and / or a serving cell index and a configuration index of the second information and / or the fourth information. The configuration of the second information and / or the fourth information configured by the one element is carried by the CG PUSCH configuration (e.g., the CG PUSCH configuration on the configured serving cell) configured by the element. This can clarify the PUSCH resources for transmitting the second information and / or the fourth information and improve the reliability of uplink transmission. It should be noted that the "serving cell index" may be replaced by the "BWP index" or the "serving cell index and BWP index". In this case, the configuration of the second information and / or the fourth information configured by the one element in the third parameter list is carried by the CG PUSCH configuration of the BWP on the configured serving cell. It should be noted that the PUSCH resources of the sixth information configuration in the embodiments of the present disclosure may be the index corresponding to an element (or resource) in the third parameter list.

[0372] In some embodiments, elements in the first parameter list may correspond one-to-one with elements in the second parameter list or elements in the third parameter list. For example, elements in the first parameter list with the same index correspond to elements in the second parameter list or elements in the third parameter list.

[0373] In some embodiments, elements in the first parameter list may correspond to one or more elements in the second parameter list or elements in the third parameter list. For example, elements in the first parameter list may be configured with corresponding one or more elements in the second parameter list or elements in the third parameter list. For example, the element index in the second parameter list or the element index in the third parameter list may be configured.

[0374] In some embodiments, elements in the second parameter list or elements in the third parameter list may correspond to one or more elements in the first parameter list. For example, elements in the second parameter list or elements in the third parameter list may be configured with corresponding one or more elements in the first parameter list. For example, the element index in the first parameter list may be configured.

[0375] It should be noted that the "element index" in the embodiments of the present disclosure may be replaced by a "PUCCH resource index" or a "PUSCH resource index".

[0376] This can clarify the correspondence relationship between the second information and the fourth information, and improve the reliability of uplink transmission.

[0377] In some embodiments, the index for configuring the second information and / or the fourth information may be configured in the CG PUSCH configuration parameter (for example, the parameter ConfiguredGrantConfig). For example, the second information and / or the fourth information corresponding to this index is carried by this CG PUSCH configuration. This can clarify the PUSCH resource for transmitting the second information and / or the fourth information, and improve the reliability of uplink transmission.

[0378] In some embodiments, a fourth parameter list may be configured, and the fourth parameter list is used to configure the SR or SR configuration or SR resource corresponding to the second information. For example, the elements in the fourth parameter list are indexes of SR or SR configuration (e.g., schedulingRequestID) or indexes of SR resources (e.g., schedulingRequestResourceId), and the index of each element in the fourth parameter list corresponds to the second information configuration with the same index. For another example, an element in the fourth parameter list includes an SR or SR configuration index (e.g., pucch-ResourceId) or an index of an SR resource (e.g., schedulingRequestResourceId) and a second information configuration index. The second information configuration configured by the one element is carried by the SR resource corresponding to the SR or SR configuration configured by the element. This can clarify the SR or SR configuration or SR resource for transmitting the second information and improve the reliability of uplink transmission. It should be noted that "the second information" can be replaced with "the tenth information".

[0379] In some embodiments, the PUCCH resource carrying the second information or the tenth information may be PUCCH format 0 and / or PUCCH format 1.

[0380] In some embodiments, a fifth parameter list may be configured, and the fifth parameter list is used to configure the first cyclic shift (cycle shift) corresponding to the second information. For example, the index of each element in the fifth parameter list corresponds to the second information configuration with the same index. Or, the index of each element in the fifth parameter list corresponds to the second information configuration with the same index + 1. For example, the first cyclic shift of index 0 in the fifth parameter list corresponds to the second information configuration of index 1. For another example, an element in the fifth parameter list includes the first cyclic shift and a second information configuration index. The cyclic shift of PUCCH format 0 carrying the second information configured by the one element is determined by the first cyclic shift. For example, the cyclic shift of PUCCH format 0 carrying the second information configured by the one element may be the sum of the initial cyclic shift of the PUCCH resource and the first cyclic shift corresponding to the second information configuration. This can clarify the cyclic shift of PUCCH format 0 for transmitting the second information and improve the reliability of uplink transmission. It should be noted that "the second information" can be replaced with "the tenth information".

[0381] In some embodiments, the correspondence between the content (e.g., indication) of the second information and the fourth information configuration may be specified by a protocol. In some embodiments, the second information "0" may correspond to the fourth information configuration with index 0, and the second information "1" may correspond to the fourth information configuration with index 1. For example, this method may be used for PUCCH format 1 in the case of BPSK modulation. In some embodiments, the second information "00" may correspond to the fourth information configuration with index 0, and the second information "01" may correspond to the fourth information configuration with index 1. The second information "10" may correspond to the fourth information configuration with index 2, and the second information "11" may correspond to the fourth information configuration with index 3. For example, this method may be used for PUCCH format 1 in the case of QPSK modulation. In some embodiments, the second information may be included in CSI part 1. The fourth information may be included in CSI part 2. For example, P bits may be newly added in CSI part 1 to indicate the twelfth information. Where P may be a positive integer. P may be specified by a protocol or configured by higher layer signaling. P may also be determined according to the number or type M of the fourth information configurations. For example, where the operator represents taking the upper bound.

[0382] In some embodiments, the second information may include the eleventh information and the twelfth information. The eleventh information may be used to indicate whether to send (or, will send or request to send) the fourth information. Or, the eleventh information may be used to indicate whether to send (or, will send or request to send) the fourth information and the twelfth information. Or, the eleventh information may be used to indicate that the UE will send or request to send the fourth information and the twelfth information. The twelfth information may be used to indicate the relevant information of the fourth information configuration. For example, the twelfth information may adopt the indication method of the second information in other embodiments of the present disclosure. In one example, the number of bits of the twelfth information is 2, and the twelfth information "00" may correspond to the fourth information configuration with index 0, the twelfth information "01" may correspond to the fourth information configuration with index 1. The twelfth information "10" may correspond to the fourth information configuration with index 2, and the twelfth information "11" may correspond to the fourth information configuration with index 3. In some embodiments, the twelfth information may be included in CSI part 1. For example, Q bits may be newly added in CSI part 1 to indicate the twelfth information. Where Q may be a positive integer. Q may be specified by a protocol or configured by higher layer signaling. Q may also be determined according to the number or type M of the fourth information configurations. For example, where the operator represents taking the upper bound. The fourth information may be included in CSI part 2. This can simplify the sending method of the second information. Avoid the situation where multiple second information overlaps with other PUCCH or PUSCH, and can reduce the implementation complexity of the UE.

[0383] In some embodiments, a sixth piece of information may include configuration information of a twelfth piece of information and a fourth piece of information and / or configuration information of an eleventh piece of information. For example, the sixth piece of information may further include at least one of the following:

[0384] - A fourth PUCCH resource, for example, a fourth PUCCH resource index. For example, the fourth PUCCH resource index may be the parameter PUCCH-ResourceId. The fourth PUCCH resource may be the PUCCH resource carrying the eleventh piece of information.

[0385] - A sixth BWP index. The sixth BWP index may be the BWP index where the fourth PUCCH resource is located (or, corresponding to).

[0386] - A fifth PUCCH resource, for example, a fifth PUCCH resource index. For example, the fifth PUCCH resource index may be the parameter PUCCH-ResourceId. The fifth PUCCH resource may be the PUCCH resource carrying the twelfth piece of information and the fourth piece of information.

[0387] - An index of a seventh BWP. The index of the seventh BWP may be the BWP index where the fifth PUCCH resource is located (or, corresponding to).

[0388] - A first PUSCH resource. The PUSCH resource may be the PUSCH resource carrying the twelfth piece of information and the fourth piece of information. The PUSCH resource may be a CG PUSCH resource. For example, a CG PUSCH configuration index parameter may be configured. For example, the parameter ConfiguredGrantConfigIndex.

[0389] - An index of a first serving cell. The index of the first serving cell is the index of the serving cell transmitting the first PUSCH.

[0390] - An index of an eighth BWP. The index of the eighth BWP is the BWP index where the first PUSCH resource is located (or, corresponding to). Or, the eighth BWP index is the BWP index on the serving cell where the first PUSCH resource is located (or, corresponding to).

[0391] - SR information corresponding to the eleventh piece of information. For example, an index of SR (for example, the parameter schedulingRequestID).

[0392] - SR resource information corresponding to the eleventh piece of information. For example, an index of the SR resource (for example, the parameter schedulingRequestResourceId).

[0393] - The number of PRBs of the fifth PUCCH resource. For example, it is used to indicate the number of PRBs occupied by the PUCCH format (e.g., PUCCH format 2, or PUCCH format 3) carrying the twelfth information and the fourth information.

[0394] It should be noted that the method for the first PUCCH resource in the embodiments of the present disclosure can also be used for the fourth PUCCH resource, and the method for the second PUCCH resource can also be used for the fifth PUCCH resource. For example, replace the first PUCCH with the fourth PUCCH and replace the second PUCCH with the fifth PUCCH.

[0395] In some embodiments, if the UE is configured with the PRB number parameter of the fifth PUCCH resource, the number of PRBs of the PUCCH format carrying the twelfth information and the fourth information sent by the UE is determined according to this parameter. This can reduce the number of times the base station blindly checks the number of PRBs, reduce the implementation complexity of the base station, and save the energy consumption of the base station.

[0396] Although the above describes a method of associating the indication of the second information with the fourth information configuration using a single bit or two bits of the second information, the exemplary embodiments of the present disclosure are equally applicable to the second information having more than two bits. Accordingly, with the second information having more than two bits, the second information can be associated with a larger number (e.g., more than four) of fourth information configurations. The corresponding relationship or mapping relationship between the indication of the second information and the fourth information configuration described above is only an example, and any suitable way can be adopted to associate the indication of the second information with the fourth information configuration. For example, although it is described that the second information with a smaller value corresponds to the fourth information configuration with a smaller index, in some embodiments, the second information with a larger value can correspond to the fourth information configuration with a smaller index.

[0397] In some embodiments, the UE transmits second information and the UE transmits fourth information. For example, the fourth information may be the fourth information corresponding to the second information (or the fourth information configuration corresponds to the fourth information). In some embodiments, the second information and the fourth information may be carried by the same physical channel (e.g., PUCCH or PUSCH), which can reduce latency and save UE power consumption. In some embodiments, the second information and the fourth information may be carried by different physical channels (e.g., PUCCH or PUSCH). For example, the UE may transmit the fourth information after transmitting the second information. Thus, when the base station does not receive the second information, the base station can reallocate the physical resources previously assigned to the fourth information respectively, thereby increasing the spectrum utilization rate. The physical channel carrying the second information (e.g., PUCCH) and the physical channel carrying the fourth information (e.g., PUCCH or PUSCH) satisfy a first predefined timing relationship. The first predefined timing relationship may be that the time interval from the physical channel carrying the second information (e.g., PUCCH) to the physical channel carrying the fourth information is not less than or greater than (or greater than or equal to) or equal to a first predefined time. The first predefined time may be specified by a protocol or configured by a higher-layer parameter. For example, the UE transmits an earliest PUCCH or PUSCH carrying the fourth information after transmitting the second information, and the time interval between this PUCCH or PUSCH and the physical channel carrying the second information is not less than or greater than (or greater than or equal to) the first predefined time. For another example, the UE transmits a PUCCH or PUSCH carrying the fourth information (e.g., an earliest PUCCH or PUSCH carrying the fourth information) after a first predefined time after transmitting the second information. For another example, the UE transmits a PUCCH carrying the fourth information in the earliest time slot (e.g., PUCCH time slot) after a first predefined time after transmitting the second information. For another example, the UE transmits a PUSCH carrying the fourth information in the earliest time slot (e.g., PUSCH time slot) after a first predefined time after transmitting the second information. It should be noted that the PUCCH or PUSCH carrying the fourth information may be the PUCCH resource (e.g., the second PUCCH resource) or PUSCH resource (e.g., the PUSCH resource configured by the sixth information) for transmitting the fourth information described in other embodiments of the present disclosure, or for another example, the PUCCH resource or PUSCH resource for transmitting the fourth information configured by a higher-layer signaling. The default value of the first predefined time may be 0, that is, if the UE is not configured with the first predefined time, then the value of the first predefined time is 0.

[0398] It should be noted that the time unit of the first predefined time can be a symbol or a time slot. The symbol or time slot can be a symbol or time slot referenced by the SCS of the primary serving cell. The symbol or time slot can also be a symbol or time slot referenced by the SCS of the serving cell where the PUSCH carrying the fourth information is located. For example, a parameter can be configured for one or more fourth information to indicate the first predefined time, which can save higher-layer signaling overhead. For another example, a parameter can be used to indicate the first predefined time for each fourth information respectively. For example, the UE can be configured with a parameter list, and one parameter in the list corresponds to one fourth information. This can improve flexibility. It should be noted that "fourth information" can be replaced by "fourth information configuration" or "second information" or "second information configuration" or "a pair or set of a second information and fourth information".

[0399] It should be noted that the PUCCH or PUSCH carrying the fourth information can be a PUCCH or PUSCH that meets the first predefined condition. The earliest PUCCH or PUSCH carrying the fourth information can be the earliest PUCCH or PUSCH that meets the first predefined condition. The first predefined condition can be at least one of the following:

[0400] - Having no overlap with the first predefined symbol. For example, the earliest PUCCH or PUSCH that meets the first predefined condition can be the earliest PUCCH or PUSCH that has no overlap with the first predefined symbol. This can avoid conflicts and improve the reliability of transmission.

[0401] The first predefined symbol can be specified by the protocol and / or configured by higher-layer signaling. For example, the first predefined symbol can be at least one of the following.

[0402] - Downlink symbols configured semi-statically (configured by higher-layer signaling) (e.g., downlink symbols configured by 3GPP parameters tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated) and / or flexible symbols.

[0403] - Symbols of the SSB (Synchronization Signal Block).

[0404] - Symbols of CORESET0. (a CORESET associated with a Type0-PDCCH CSS set)

[0405] - Symbols configured as unavailable by higher-layer signaling.

[0406] - Y symbols after SSB. Y is an integer and can be specified by the protocol and / or configured by higher layer signaling.

[0407] - Inactive symbols of cell DRX (discontinuous reception).

[0408] - Downlink symbols and / or flexible symbols indicated by DCI format 2_0.

[0409] - Symbols of downlink physical channels or signals on the same serving cell (e.g., the symbols occupied by physical channels or signals). For example, symbols of a downlink physical channel or signal indicated by DCI format. Another example is symbols of a downlink physical channel or signal configured by higher layer signaling.

[0410] - Symbols of uplink physical channels or signals on the same serving cell. For example, symbols of an uplink physical channel or signal indicated by DCI format. Another example is symbols of an uplink physical channel or signal configured by higher layer signaling. For example, symbols of another PUSCH transmission indicated by DCI format on the same serving cell.

[0411] In some embodiments, the second transmission opportunity of a physical channel carrying the second information may be associated with the fourth transmission opportunities of A physical channels carrying the fourth information. For example, A can be 1. Another example is that A can be an integer greater than 1. If the fourth transmission opportunities associated with a second transmission opportunity (e.g., all the fourth transmission opportunities associated with the second transmission opportunity) cannot be sent (or, overlap with the first predefined symbols), the UE does not send the second information at the second transmission opportunity. And / or, if the fourth transmission opportunities associated with a second transmission opportunity (e.g., at least one of the fourth transmission opportunities associated with a second transmission opportunity) do not overlap with the first predefined symbols, the UE may send the second information at the second transmission opportunity. This can reduce the transmission power of the UE.

[0412] In some embodiments, the fourth transmission opportunities associated with a second transmission opportunity may be at least one of the following:

[0413] - The fourth transmission opportunity that satisfies the interval from the second transmission opportunity to the fourth transmission opportunity being the first predefined time. Among them, the fourth transmission opportunity is later than the second transmission opportunity.

[0414] - The earliest A fourth transmission opportunities that satisfy the interval from the second transmission opportunity to the fourth transmission opportunity being not less than the first predefined time. Among them, the fourth transmission opportunity is later than the second transmission opportunity.

[0415] In some embodiments, at least one of the following may be configured by protocol stipulation and / or higher layer signaling:

[0416] - The UE does not expect the PUCCH or PUSCH carrying the fourth information to overlap with the downlink physical channel or signal indicated by the DCI format on the same serving cell. This can reduce the transmission delay of the fourth information.

[0417] - The UE does not expect the PUCCH or PUSCH carrying the fourth information to overlap with the uplink physical channel or signal indicated by the DCI format on the same serving cell. This can reduce the transmission delay of the fourth information.

[0418] - The UE does not expect the PUSCH carrying the fourth information to overlap with another PUSCH indicated by the DCI format on the same serving cell. This can reduce the transmission delay of the fourth information.

[0419] It should be noted that in the above embodiments, the UE may measure the second RS after sending the second information, and then the UE sends the fourth information. This can save the signaling overhead of the RS, thereby improving the spectrum utilization rate. The physical channel (e.g., PUCCH) carrying the second information and the second RS satisfy a second predefined timing relationship, and the second predefined timing relationship may be that the time interval from the physical channel (e.g., PUCCH) carrying the second information to the second RS is not less than or greater than (or greater than or equal to) the second predefined time. The second predefined time may be stipulated by the protocol or configured by higher layer parameters. For example, the UE measures an earliest second RS after sending the second information, and the time interval between the second RS and the physical channel carrying the second information is not less than or greater than (or greater than or equal to) the second predefined time. In some embodiments, the UE may be configured by higher layer signaling to measure the second RS after sending the second information. The UE may also support measuring the second RS after sending the second information through UE capability reporting. Among them, measuring the second RS after sending the second information may be measuring the second RS before sending the fourth information. It should be noted that the "second RS" may be replaced by "RS" or "first and / or second RS". This can improve the scheduling flexibility.

[0420] In some embodiments, if the fourth information determined by the UE at the sixth time is different from the fourth information determined at the seventh time, the UE does not send the fourth information. And / or, if the fourth information determined at the sixth time is the same as the fourth information determined at the seventh time, the UE sends the fourth information. Among them, the sixth time and the seventh time satisfy a third condition. For example, the third condition may include at least one of the following:

[0421] - The sixth time may be earlier than the seventh time;

[0422] - The sixth time can be earlier than the physical channel carrying the second information;

[0423] - The seventh time can be later than the physical channel carrying the second information.

[0424] - The seventh time can be earlier than the physical channel carrying the fourth information;

[0425] - The sixth time can also be the time triggered by an event corresponding to the second information.

[0426] - The seventh time can be later than the time triggered by an event corresponding to the second information.

[0427] - The seventh time can be the time triggered by an event corresponding to another second information.

[0428] It should be noted that the physical channel carrying the fourth information can be the physical channel carrying the fourth information associated with the physical channel carrying the second information. "The physical channel carrying the fourth information" can be replaced by "the transmission opportunity of the physical channel carrying the fourth information", and "the physical channel carrying the second information" can be replaced by "the transmission opportunity of the physical channel carrying the second information". This method can save the transmission power of the UE.

[0429] It should be noted that the UE can indicate support for the above method through a separate UE capability report.

[0430] In one example, if the determined fourth information after the UE sends the second information is different from the determined fourth information before sending the second information, the UE does not send the fourth information. And / or, if the determined fourth information after the UE sends the second information is the same as the determined fourth information before sending the second information, the UE sends the fourth information. This can save the transmission power of the UE.

[0431] It should be noted that in the embodiments of the present disclosure, sending the second information can be understood as sending the physical channel or signal carrying the second information. The second information can be replaced by the fourth information or other information.

[0432] In some embodiments, at least one of the first information, the third information, the fifth information, the sixth information or the ninth information can be configured in the physical cell group configuration parameter (for example, the parameter PhysicalCellGroupConfig) or the MAC cell group configuration parameter (for example, the parameter MAC-CellGroupConfig), which can save signaling overhead.

[0433] It should be noted that the "serving cell" in the embodiments of the present disclosure can be replaced by the "BWP on the serving cell" or "BWP".

[0434] It should be noted that in the embodiments of the present disclosure, the "second information" may be replaced by the "positive second information", and the "tenth information" may be replaced by the "positive tenth information".

[0435] It should be noted that in the embodiments of the present disclosure, the PUCCH resource or the PUSCH resource may also be configured with a period and / or an offset. The number of the offsets may be one or more. If a PUCCH resource or a PUSCH resource is not configured with a period, it can be considered that the period of the PUCCH resource or the PUSCH resource is 1 time slot. For example, the period of the second PUCCH resource or PUSCH resource may be N symbols, where N may be 2 or 6 or 7. Compared with a period of M time slots, a period less than one time slot can reduce the uplink transmission delay.

[0436] It should be noted that the second information or the fourth information in the embodiments of the present disclosure may also be used to indicate other UCI information and / or uplink data.
