The receive path 250 includes a down-converter (DC) 255, a cyclic prefix removal block 260, a serial-to-parallel (S-to-P) block 265, an N-point fast Fourier transform (FFT) block 270, a parallel-to-serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

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

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

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

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

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

[0080] although Figure 2a and Figure 2b An example of a wireless transmit and receive path is shown, but it is possible to modify it further. Figure 2a and Figure 2b Make various changes. For example, Figure 2a and Figure 2b The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. Furthermore, Figure 2a and Figure 2b This is intended to illustrate examples of the types of send and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.

[0081] Figure 3a Example UE 116 according to this disclosure is shown. Figure 3a The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1 UEs 111-115 can have the same or similar configurations. However, UEs have a wide variety of configurations, and Figure 3a This disclosure is not intended to limit the scope of any particular implementation of the UE.

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

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

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

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

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

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

[0088] although Figure 3a An example of UE 116 is shown, but it is possible to... Figure 3a Make various changes. For example, Figure 3a The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. As a specific example, the controller / processor 307 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although... Figure 3a The UE116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0089] Figure 3b An example gNB 102 according to this disclosure is shown. Figure 3b The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a wide variety of configurations, and Figure 3b The scope of this disclosure is not limited to any particular implementation of the gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structures as gNB 102.

[0090] like Figure 3b As shown, gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376. In some embodiments, one or more of the multiple antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0091] RF transceivers 372a-372n receive incoming RF signals, such as signals transmitted by the UE or other gNBs, from antennas 370a-370n. RF transceivers 372a-372n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 376, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 376 sends the processed baseband signals to controller / processor 378 for further processing.

[0092] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from the controller / processor 378. The TX processing circuit 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 372a-372n receive the outgoing processed baseband or IF signal from the TX processing circuit 374 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.

[0093] The controller / processor 378 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 may control the reception of forward channel signals and the transmission of reverse channel signals via RF transceivers 372a-372n, RX processing circuitry 376, and TX processing circuitry 374, according to known principles. The controller / processor 378 may also support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 378 may perform a BIS process, such as by a blind interference sensing (BIS) algorithm, and decode the received signal after subtracting interference. The controller / processor 378 may support any of a wide variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0094] The controller / processor 378 is also capable of executing programs and other processes, such as a basic operating system, residing in the memory 380. The controller / processor 378 is also capable of supporting channel quality measurement and reporting for systems having 2D antenna arrays as described in embodiments of this disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTCs. The controller / processor 378 is capable of moving data into or out of the memory 380 as needed for the execution of processes.

[0095] The controller / processor 378 is also coupled to a backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or over a network. The backhaul or network interface 382 is capable of supporting communication via any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G or new radio access technologies or NR, LTE, or LTE-A), the backhaul or network interface 382 allows the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the backhaul or network interface 382 allows the gNB 102 to communicate with a larger network (such as the Internet) via a wired or wireless local area network or via a wired or wireless connection. The backhaul or network interface 382 includes any suitable architecture supporting communication via a wired or wireless connection, such as an Ethernet or RF transceiver.

[0096] Memory 380 is coupled to controller / processor 378. A portion of memory 380 may include RAM, while another portion may include flash memory or other ROM. In some embodiments, multiple instructions, such as a BIS algorithm, are stored in memory. The multiple instructions are configured to cause controller / processor 378 to perform the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.

[0097] As described in more detail below, the transmit and receive paths of the gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuitry 374, and / or RX processing circuitry 376) support aggregated communication with FDD and TDD cells.

[0098] although Figure 3b An example of gNB 102 is shown, but it is possible to compare it with other models. Figure 3b Various modifications can be made. For example, gNB102 can include any number of... Figure 3a Each component shown. As a specific example, an access point can include multiple backhaul or network interfaces 382, ​​and a controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as a single instance including TX processing circuitry 374 and a single instance including RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0099] Exemplary embodiments of this disclosure are further described below with reference to the accompanying drawings.

[0100] The text and accompanying drawings are provided by way of example only to aid the reader in understanding this disclosure. They are not intended and should not be construed as limiting the scope of this 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 may be made to the illustrated embodiments and examples without departing from the scope of this disclosure.

[0101] Transmissions in a wireless communication system may include: transmissions from a base station (e.g., gNB) to a user equipment (UE) (which may be called downlink transmissions), and the corresponding time slots may be called downlink time slots; and transmissions from the UE to the base station (which may be called uplink transmissions), and the corresponding time slots may be called uplink time slots.

[0102] In this disclosure, a "frequency domain resource group" refers to a continuous segment of spectrum resources (or frequency domain resources). A UE can transmit or receive physical channels and / or physical signals on a frequency domain resource group. In essence, a frequency domain resource group is a continuous segment of spectrum resources that a UE can use to transmit or receive signals.

[0103] Figure 4 A schematic diagram of a frequency domain resource group according to an embodiment of the present disclosure is shown. Figure 4 As shown, the first frequency domain resource group has a bandwidth of X MHz, which may include X0 subcarriers; the second frequency domain resource group has a bandwidth of Y MHz, which may include Y0 subcarriers. X0 and Y0 can be any positive integers. In some embodiments, there may be a certain interval, for example, Z MHz, between the highest index subcarrier of the first frequency domain resource group and the lowest index subcarrier of the second frequency domain resource group. In some embodiments, the highest index subcarrier of the first frequency domain resource group and the lowest index subcarrier of the second frequency domain resource group may be consecutive.

[0104] In this disclosure, the frequency domain resource group can also be equivalently replaced by one of the following: carrier, bandwidth part, carrier segment, or carrier segment.

[0105] In this disclosure, the first frequency domain resource group may include a first uplink frequency domain resource group and / or a first downlink frequency domain resource group, and the second frequency domain resource group may include a second uplink frequency domain resource group and / or a second downlink frequency domain resource group. In the following text, for ease of description, the first uplink frequency domain resource group and / or the first downlink frequency domain resource group may be simply referred to as the first frequency domain resource group, and the second uplink frequency domain resource group and / or the second downlink frequency domain resource group may be simply referred to as the second frequency domain resource group.

[0106] In mobile communication systems, a single operator typically possesses multiple available contiguous spectrum bands, and the bandwidth of contiguous spectrum in the Sub-3 GHz band (especially the Sub-1 GHz band) is generally small. In the Sub-3 GHz spectrum, 95% of the contiguous 1.4–2.6 GHz FDD (Frequency Division Duplex) spectrum has a bandwidth of no more than 30 MHz, and 90% of operators own more than one 1.4–2.6 GHz FDD band. Similarly, the Sub-1 GHz spectrum (e.g., 700 / 800 / 900 MHz) faces the same issue. 93% of the contiguous sub-1 GHz FDD spectrum has a bandwidth of no more than 15 MHz, and 71% of operators own more than one sub-1 GHz FDD band. Although these FDD bands are not contiguous in the spectrum, the aggregated bandwidth formed by combining these bands is still considerable. Aggregated FDD carriers can provide similar DL (Downlink) bandwidth and 2.4 times the UL (Uplink) bandwidth as C-band TDD (Time Division Duplex) carriers. More importantly, the Sub-3 GHz spectrum offers coverage advantages. In addition to the aforementioned FDD bands, there are several Supplementary Uplink (SUL) bands in the Sub-3 GHz range (e.g., n97, n98, n95) that can be used to improve operators' UL coverage and capacity. In the future, operators will deploy more Sub-3 GHz spectrum to meet the growing demands of both ToB (To Business) and ToC (To Customer) scenarios. Furthermore, as more spectrum is allocated for mobile communications, operators will deploy more spectrum across various frequency bands to meet the increasing demand for data rates.

[0107] Figure 5 A schematic diagram of a virtual carrier according to an embodiment of the present disclosure is shown.

[0108] like Figure 5 As shown, four frequency domain resource groups with bandwidths of 5MHz, 10MHz, 20MHz, and 15MHz can constitute a virtual carrier with a bandwidth of 50MHz. These four frequency domain resource groups can belong to different frequency bands. Figure 5 It can be seen that a virtual carrier can be formed by aggregating multiple frequency domain resource groups with discontinuous frequencies, and the bandwidth of a virtual carrier can be the sum of the bandwidths of the multiple frequency domain resource groups that constitute the virtual carrier.

[0109] Furthermore, the multiple frequency domain resource groups constituting the virtual carrier may include spectrum allocated to different communication systems. For example, one of these frequency domain resource groups may be spectrum belonging to a 6G system, while another frequency domain resource group may be spectrum originally belonging to a 5G system but reassigned to a 6G system.

[0110] Among the multiple frequency domain resource groups constituting a virtual carrier, the frequency domain resource group used for transmitting the SSB (Synchronization Signal and PBCH block) and SIB1 (System Information Block 1) can be called the primary frequency domain resource group or the first frequency domain resource group, while the other frequency domain resource groups are called secondary frequency domain resource groups or the second frequency domain resource group. When multiple secondary frequency domain resource groups exist, these multiple secondary frequency domain resource groups can also be called the second frequency domain resource group, the third frequency domain resource group, the fourth frequency domain resource group, and so on.

[0111] Besides the aforementioned method of using virtual carriers to utilize multiple frequency domain resources, carrier aggregation can also be used. That is, the network deploys one cell on each carrier segment. To facilitate network management and scheduling of UEs, it is desirable that idle UEs camp on a designated carrier, transmitting SSB and SIB1 only on one of the multiple carriers, while the other carriers serve as secondary cells to provide services to the UE.

[0112] In another scenario, multiple carriers (frequency domain resource groups) can be deployed within a serving cell. These carriers can have different functions; for example, one of the carriers can be referred to as the anchor carrier. The anchor carrier can have at least one of the following functions:

[0113] (1) Provide initial synchronization and basic system information transmission for UEs within the cell. For example, at least one or more of the following should be periodically transmitted on the downlink anchor carrier: a synchronization signal (SS), a physical broadcast channel (PBCH), and a first system information block (SIB 1). The synchronization signal may include a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). For example, the downlink anchor carrier should at least be used to transmit the SSB and SIB1 for cell definition (CD).

[0114] (2) Provide initial random access functionality for UEs within the cell, for example, resources on the uplink anchor carrier that can be used to configure the cell-common physical random access channel (PRACH);

[0115] (3) Provide mobility management functions for UEs within the cell. For example, the UE performs measurements for radio resource management (RRM) purposes based only on reference signals (such as SSB and / or CSI-RS) on the downlink anchor carrier, without having to perform RRM measurements on other carriers.

[0116] To achieve the above functions, anchor carriers are generally at lower frequencies and / or have a wider coverage area compared to other carriers. Furthermore, anchor carriers can also provide basic data transmission capabilities for UEs within the cell.

[0117] A carrier other than the anchor carrier can serve as a supplement to the anchor carrier and is therefore called a supplementary carrier. For a supplementary downlink (SDL), the SDL is mainly used to supplement data transmission services, for example, providing data transmission services with a higher peak rate than the anchor carrier. For a supplementary uplink (SUL), the SUL is used to supplement data transmission services and / or to supplement coverage, for example, providing data transmission services with a higher peak rate than the anchor carrier and / or providing wider coverage than the anchor carrier.

[0118] In this disclosure, the anchor carrier may also be referred to as the primary carrier, or other technical terms such as ordinary carrier, and may correspond to the first frequency domain resource group mentioned above; the supplementary carrier may also be referred to as the secondary carrier, data carrier, or other technical terms, and may correspond to the second frequency domain resource group mentioned above.

[0119] In this disclosure, the names of any parameters, information, or messages are merely examples and may have any other names depending on the application scenario.

[0120] Furthermore, some operators' available spectrum does not match the channel bandwidth specified by the NR system. For example, in the n5 band, operators have channel bandwidths of 7MHz and 11MHz, which do not conform to the NR system's specified channel bandwidths of 5MHz and 10MHz. Using overlapping CA (Carrier Aggregation) schemes can support the use of irregular spectrum without introducing new dedicated channel bandwidth for the UE and base station (BS). From the network perspective, for overlapping CA, the BS supports in-band overlapping CA, while the UE only supports a single CC (Component Carrier) with existing channel bandwidth. From the UE perspective, both the BS and UE support in-band overlapping CA using all RBs (Resource Blocks), and the UE also supports combining in-band non-contiguous CAs. This approach can be applied to irregular channel bandwidths of various sizes without requiring the definition of new channel filters to be designed and tested for the BS and UE.

[0121] Optionally, the first downlink frequency domain resource group and the second downlink frequency domain resource group can be contiguous. The first downlink frequency domain resource group and the second downlink frequency domain resource group can belong to different cells, and there can be at least one overlapping frequency domain resource element between them. Alternatively, the first downlink frequency domain resource group and the second downlink frequency domain resource group can belong to the same cell, and the UE uses two sets of filters to receive the first downlink frequency domain resource group and the second downlink frequency domain resource group respectively. This requires the UE to have specific capabilities, such as the ability to use two sets of filters simultaneously.

[0122] Based on the scenarios described above, when an operator has multiple consecutive spectrum resources available, they can use them as a single cell by deploying one or more consecutive spectrum resources on each spectrum segment. The physical meaning of consecutive spectrum resources is a set, which can include N0 (N0 is a positive integer) consecutive resource elements or resource blocks in the frequency domain, where each resource element can be an OFDM subcarrier. A resource block can include a certain number of consecutive resource elements. Optionally, a resource block can contain 12 consecutive resource elements. Resource blocks can also be common resource blocks, physical resource blocks, virtual resource blocks, etc., where the reference position of the index of a common resource block (or, physical resource block, or virtual resource block) can be the minimum index subcarrier of a frequency domain resource group, a predefined or configured frequency domain reference point, or the minimum index subcarrier of other frequency domain resource groups.

[0123] When a cell has multiple frequency domain resource groups, for a UE in an idle / inactive state, system information (such as SSB, SIB, RMSI (Remaining Minimum System Information), and OSI (Other System Information)) and paging of the serving cell can only be broadcast in one of the multiple downlink frequency domain resource groups within the serving cell. System information can include the necessary information for each frequency domain resource group (such as frequency, bandwidth, SCS (Sub-Carrier Spacing), RACH (Random Access Channel) resources, etc.). Therefore, the UE can obtain information from all frequency domain resource groups and access all frequency domain resource groups.

[0124] In some implementations, the UE can receive SSB and system information in the first (or anchored) downlink frequency domain resource group, and can perform initial access on the first (or anchored) uplink frequency domain resource group.

[0125] In this disclosure, a frequency domain resource unit (also referred to as a frequency resource unit, frequency domain unit, or frequency unit, etc.) can be: a subcarrier, a subcarrier group (composed of multiple subcarriers), a resource block (RB), also referred to as a physical resource block (PRB), a resource block group (composed of multiple RBs), a bandwidth portion (BWP), a bandwidth portion group (composed of multiple BWPs), a frequency band / carrier, a frequency band group / carrier group, etc.; it can also be an absolute frequency domain unit, such as 1 Hz, 1 kHz, etc.; the frequency domain unit can also be a combination of multiple granularities, such as M1 PRBs plus M2 subcarriers, etc., where M1 and M2 are integers greater than or equal to 0.

[0126] In this disclosure, a time-domain resource unit (also referred to as a time resource unit, time-domain unit, or time unit, etc.) can be: an OFDM symbol, an OFDM symbol group (composed of multiple OFDM symbols), a slot, a slot group (composed of multiple slots), a subframe, a subframe group (composed of multiple subframes), a system frame, a system frame group (composed of multiple system frames), etc.; it can also be an absolute time unit, such as 1 millisecond, 1 second, etc.; the time unit can also be a combination of multiple granularities, such as N1 slots plus N2 OFDM symbols, etc. (where N1 and N2 are integers greater than or equal to 0); it can also be the time length of an OOK (On-Off Keying) chip.

[0127] In this disclosure, the Physical Downlink Control Channel (PDCCH) can be used to schedule DL transmissions on the Physical Downlink Shared Channel (PDSCH) and UL transmissions on the Physical Uplink Shared Channel (PUSCH), wherein the Downlink Control Information (DCI) on the PDCCH may include:

[0128] - Downlink allocation, which includes at least modulation and coding formats, resource allocation, and hybrid ARQ information related to DL-SCH;

[0129] - Uplink scheduling permission, which includes at least modulation and coding formats, resource allocation, and hybrid ARQ information related to UL-SCH.

[0130] Besides scheduling, PDCCH can also be used for:

[0131] - Activate and deactivate configured PUSCH transports using the configured authorization;

[0132] - Activation and deactivation of PDSCH semi-persistent transport;

[0133] - Notify one or more UEs of their slot format;

[0134] - Notify one or more UEs of the PRB and OFDM symbols, where the UEs may assume that no transmission is directed to the UE;

[0135] - Transmit TPC commands for PUCCH and PUSCH;

[0136] - One or more TPC commands for SRS transmission are sent by one or more UEs;

[0137] - Switch the active bandwidth portion of the UE;

[0138] - Initiate the random access procedure;

[0139] - Instruct the UE to monitor the PDCCH during the next DRX on duration;

[0140] - In the context of Integrated Access and Backhaul (IAB), indicate the availability of soft symbols for IAB-DU;

[0141] - Trigger a single HARQ-ACK codebook feedback;

[0142] - Operations for shared spectrum channel access include at least one of the following:

[0143] - Triggers a switch in the search space set group;

[0144] - Indicate the available RB set and channel occupancy duration to one or more UEs;

[0145] - Indicates downlink feedback information (CG-DFI) for configuration authorization (CG)PUSCH.

[0146] In describing wireless communication systems and in this disclosure described below, higher-layer signaling or higher-layer signaling can be a signaling method for transmitting information from a base station to a terminal via a downlink data channel of the physical layer or from a terminal to a base station via an uplink data channel of the physical layer, and examples of signaling methods can include signaling methods for transmitting information via radio resource control (RRC) signaling, packet data convergence protocol (PDCP) signaling, or medium access control (MAC) control element (CE).

[0164] In embodiments of this disclosure, uplink transmission can refer to any uplink channel and / or uplink signal, such as PUCCH, PUSCH, UCI, etc. Downlink transmission can refer to any downlink channel and / or downlink signal, such as PDCCH, PDSCH, DCI, etc.

[0165] In this disclosure, parameters, information, and related information are used interchangeably.

[0166] In this disclosure, without causing confusion, both uplink carrier and downlink carrier may be referred to simply as carrier.

[0167] In an NR system, each cell includes one or two uplink carriers. After receiving SIB1, the UE can determine whether to use a normal uplink carrier (NUL) or a supplementary uplink carrier (SUL) based on SIB1. In the case of carrier aggregation, the UE can transmit PUCCH on the primary cell (PCell). If the UE is configured to transmit PUCCH in a secondary cell (e.g., PUCCH-SCell), the UE can transmit PUCCH on both the PCell and the SCell configured to transmit PUCCH. PUCCH can be used to transmit uplink control information (UCI). Furthermore, UCI can also be transmitted in other uplink channels / uplink signals such as PUSCH. When a cell includes multiple uplink carriers, the UE can use multiple carriers. How to transmit UCI on multiple uplink carriers when the UE uses multiple carriers to transmit uplink transmissions is a problem that needs to be solved.

[0168] In the following description, PUSCH will be used as an example of uplink transmission.

[0169] One aspect of this disclosure provides a method performed by a user equipment (UE) in a wireless communication system, the method comprising at least one of the following steps.

[0170] Step 1.1: The UE receives first information from the base station for scheduling or configuring the PUSCH, such as downlink control information (DCI) for scheduling the PUSCH and / or configuration information related to the CG PUSCH.

[0171] In some implementations, the first information may include second information related to a first physical resource used for PUSCH. More specifically, the second information may include information about one or more carriers or carrier bundles used for PUSCH, and / or information about one or more specific physical resources (e.g., RE / RB, etc.) used for PUSCH. In some implementations, the first physical resource may include physical resources in at least two uplink carriers within the cell.

[0172] Step 1.2: The UE generates the bit sequence of the UCI and encodes the bit sequence of the UCI.

[0173] Step 1.3: The UE multiplexes the bit sequence of the encoded UCI into the first part of the PUSCH.

[0174] In some implementations, the first portion of the PUSCH may be located in a first carrier group comprising one or more of at least two uplink carriers. The first carrier group may be determined based on a first power threshold and / or a first power associated with the PUSCH. The first power may be associated with the transmission power of the PUSCH on each of the at least two uplink carriers. For example, the first power may be the sum of one or more calculated transmission powers of the PUSCH on each of the at least two uplink carriers, or a weighted sum thereof, etc.

[0175] In some implementations, the first portion of the PUSCH may be physical resources for the PUSCH on all carriers scheduled or configured for the PUSCH. In some implementations, the first portion of the PUSCH may be physical resources for the PUSCH on at least one carrier scheduled or configured for the PUSCH.

[0176] Step 1.4: The UE sends the PUSCH or the first part of the PUSCH to the base station.

[0177] Figure 6 An example process of a method performed by a UE in a wireless communication system according to an embodiment of the present disclosure is shown.

[0178] Figure 6An example scenario is illustrated below. A UE is configured to perform uplink transmissions on cells 1 and 2. Cell 1 comprises three carriers, for example, carrier 1, carrier 2, and carrier 3. Cell 2 is a single-carrier cell, comprising carrier 4. The UE receives a DCI on carrier 1 for scheduling the first PUSCH. This DCI instructs the UE to transmit the first PUSCH in specific physical resources on carriers 1, 2, and 3 after a time period T1 following the receipt of the DCI. The UE can transmit part 1 of the first PUSCH on carrier 1, part 2 on carrier 2, and part 3 on carrier 3. Furthermore, when the UE is configured to transmit a PUCCH or a UCI on cell 1, the UE needs to transmit a PUCCH on cell 1, where the UCI is carried within the PUCCH. Specifically, when UCI and PUSCH transmissions are time-coordinated, whether due to the transmission of a UL-SCH transport block or due to the triggering of a-CSI transmission in the absence of a UL-SCH transport block, and associated with the same priority (high / low), UCI multiplexing in the PUSCH is supported. Furthermore, when HARQ-ACK and PUSCH transmissions are time-coordinated, whether due to the transmission of a UL-SCH transport block or due to the triggering of a-CSI transmission in the absence of a UL-SCH transport block, HARQ-ACK multiplexing of a specific priority PUSCH is supported in PUSCHs of different priorities: UCI carrying 1 or 2 bits of HARQ-ACK feedback is multiplexed via punctured PUSCH; in all other cases, UCI is multiplexed via rate matching for PUSCH. For example, if a UE receives downlink transmissions, such as PDSCH, on carrier 3 in cell 1 and carrier 4 in cell 2, and the HARQ feedback and PUSCH transmission of these two PDSCHs are synchronized in time, then the HARQ feedback of these two PDSCHs needs to be sent in the first PUSCH in cell 1.

[0179] The UE can determine the uplink transmission power allocation based on one or more of the following: a first power threshold, the priority of the first and second PUSCHs, the priority of each carrier, and the transmission power of the PUSCH on each carrier. For example, if the sum of the uplink transmission power of the UE on cell 1 (e.g., carriers 1, 2, and 3) and / or cell 2 (e.g., carrier 4) exceeds the first power threshold, the UE can further reduce the transmission power of uplink transmissions on one or more of carriers 1, 2, 3, and 4 based on carrier priority information (e.g., carrier priority order), and / or drop uplink transmissions on one or more of carriers 1, 2, 3, and 4 based on priority information. Assuming that based on the first power threshold and carrier priority information, the UE discards part 3 of the first PUSCH on carrier 3 and the second PUSCH on carrier 4, that is, the UE determines that the first part of the first PUSCH used for multiplexing UCI is the physical resources for the first PUSCH on carrier 1 and carrier 2 (i.e., part 1 of the first PUSCH on carrier 1 and part 2 of the first PUSCH on carrier 2), then the UE can multiplex UCI into part 1 of the first PUSCH on carrier 1 and part 2 of the first PUSCH on carrier 2.

[0180] Another aspect of this disclosure provides a method performed by a user equipment (UE) in a communication system, the method comprising at least one of the following steps.

[0181] Step 2.1: The UE receives first information from the base station for scheduling or configuring the PUSCH, such as downlink control information (DCI) for scheduling the PUSCH and / or configuration information related to the CG PUSCH.

[0182] In some implementations, the first information may include second information related to a first physical resource used for PUSCH. More specifically, the second information may include information about one or more carriers or carrier bundles used for PUSCH, and / or information about one or more specific physical resources (e.g., RE / RB, etc.) used for PUSCH. In some implementations, the first physical resource may include physical resources in at least two uplink carriers within the cell.

[0183] Step 2.2: The UE generates the bit sequence of the UCI and encodes the bit sequence of the UCI.

[0184] Step 2.3: The UE multiplexes the encoded UCI bit sequence in the PUSCH. For example, the UE can multiplex the encoded UCI bit sequence on all carriers used for the PUSCH. In some implementations, the physical resources of the PUSCH can be determined based on the first information.

[0185] Step 2.4: If the first power-related condition associated with PUSCH is met (e.g., if the first power associated with PUSCH is greater than the first power threshold), the UE re-multiplexes the bit sequence of the encoded UCI in the first part of PUSCH.

[0186] Step 2.5: The UE sends a PUSCH or the first part of the PUSCH to the base station.

[0187] In some implementations, the first portion of the PUSCH may be located in a first carrier group comprising one or more of at least two uplink carriers. The first carrier group may be determined based on a first power threshold and / or a first power associated with the PUSCH. The first power may be associated with the transmission power of the PUSCH on each of the at least two uplink carriers. For example, the first power may be the sum of one or more calculated transmission powers of the PUSCH on each of the at least two uplink carriers, or a weighted sum thereof, etc.

[0188] Figure 7 An example process of another method performed by a UE in a wireless communication system according to an embodiment of the present disclosure is shown.

[0189] Figure 7An example scenario is illustrated below. A UE is configured to perform uplink transmissions on cells 1 and 2. Cell 1 comprises three carriers, for example, carrier 1, carrier 2, and carrier 3. Cell 2 is a single-carrier cell, comprising carrier 4. The UE receives a DCI on carrier 1 for scheduling the first PUSCH. This DCI instructs the UE to transmit the first PUSCH in specific physical resources on carriers 1, 2, and 3 after a time period T1 following the receipt of the DCI. The UE can transmit part 1 of the first PUSCH on carrier 1, part 2 on carrier 2, and part 3 on carrier 3. Furthermore, when the UE is configured to transmit a PUCCH or a UCI on cell 1, the UE needs to transmit a PUCCH on cell 1, where the UCI is carried within the PUCCH. Specifically, when UCI and PUSCH transmissions are time-coordinated, whether due to the transmission of a UL-SCH transport block or due to the triggering of a-CSI transmission in the absence of a UL-SCH transport block, and associated with the same priority (high / low), UCI multiplexing in the PUSCH is supported. Furthermore, when HARQ-ACK and PUSCH transmissions are time-coordinated, whether due to the transmission of a UL-SCH transport block or due to the triggering of a-CSI transmission in the absence of a UL-SCH transport block, HARQ-ACK multiplexing of a specific priority PUSCH is supported in PUSCHs of different priorities: - UCI carrying 1 or 2 bits of HARQ-ACK feedback is multiplexed via punctured PUSCH; - In all other cases, UCI is multiplexed via rate matching for PUSCH. For example, suppose the UE receives downlink transmissions, such as PDSCH, on carrier 3 in cell 1 and carrier 4 in cell 2 respectively. The HARQ feedback and PUSCH transmission of the two PDSCHs are synchronized in time. Then the HARQ feedback of the two PDSCHs needs to be sent in the first PUSCH in cell 1.

[0190] First, the UE can multiplex the UCI, including HARQ feedback, in the first PUSCH, for example, in the resources for the first PUSCH on carrier 1, carrier 2 and carrier 3.

[0191] Then, the UE can determine the uplink transmission power allocation based on one or more of the following: a first power threshold, the priority of the first and second PUSCHs, the priority of each carrier, and the transmission power of the PUSCH on each carrier. For example, if the sum of the uplink transmission power of the UE on cell 1 (e.g., carriers 1, 2, and 3) and / or cell 2 (e.g., carrier 4) is greater than the first power threshold, the UE can further reduce the transmission power of the uplink transmission on one or more of carriers 1, 2, 3, and 4 based on carrier priority information (e.g., carrier priority order), and / or drop the uplink transmission on one or more of carriers 1, 2, 3, and 4 based on priority information. Assuming that based on the first power threshold and carrier priority information, the UE discards part 3 of the first PUSCH on carrier 3 and the second PUSCH on carrier 4, that is, the UE determines that the first part of the first PUSCH used for reusing UCI is the physical resources for the first PUSCH on carrier 1 and carrier 2 (i.e., part 1 of the first PUSCH on carrier 1 and part 2 of the first PUSCH on carrier 2), then the UE can re-reuse UCI into part 1 of the first PUSCH on carrier 1 and part 2 of the first PUSCH on carrier 2.

[0192] In some implementations, the UE can be configured to transmit a first cell and / or carrier (and / or carrier bundling) for PUCCH and / or UCI. In some implementations, the first cell may include at least two uplink carriers. For example, the UE may receive an RRC message, which may include information indicating the first cell for transmitting PUCCH and / or UCI, and / or information about the uplink carrier (and / or carrier bundling) for transmitting PUCCH and / or UCI.

[0193] In one example, the RRC message may include a first parameter that indicates the carrier in the first cell used for PUCCH. The RRC message may include a system message (or system information, such as SIB1) or a UE-specific RRC message (e.g., PDSCH-ServingCellConfig). For example, the first parameter may be PUCCH-carrier, indicating the carrier (and / or carrier bundle) in the first cell (or first serving cell) used for transmitting PUCCH and / or UCI. If this field is omitted, or if the UE is not configured to use a carrier for transmitting PUCCH and / or UCI, the UE may send HARQ feedback using one of the following: an anchor carrier, a carrier with an index of 0 (or any other specified value), a carrier bundle with an index of 0 (or any other specified value), etc. A carrier bundle may include at least two uplink carriers.

[0194] In another example, the RRC message may include a second parameter indicating whether one or more uplink carriers (and / or carrier bundles) in the first cell are used to transmit PUCCH and / or UCI. For example, the RRC message may be uplinkConfigCommon, which may include information indicating one or more uplink carriers (and / or carrier bundles) for the first cell, and information on whether each of the one or more uplink carriers (and / or carrier bundles) can be used to transmit PUCCH and / or UCI.

[0195] In some implementations, the carriers and / or carrier bundles selected or determined by the UE for transmitting PUCCH and / or UCI can be a subset of the carriers or carrier bundles configured in the RRC message for transmitting PUCCH and / or UCI. For example, assuming the RRC message received by the UE configures the carriers for transmitting PUCCH and / or UCI as a first carrier and a second carrier, and the DCI message received by the UE schedules the UE to transmit PUSCH on the first carrier, then the UE can select the first carrier for transmitting PUCCH and / or UCI, and the UE can multiplex UCI onto the PUSCH on the first carrier. As another example, assuming the RRC message received by the UE configures the carriers for transmitting PUCCH and / or UCI as a first carrier and a second carrier, and the DCI message received by the UE schedules the UE to transmit PUSCH on the first carrier and the second carrier, then the UE can select the first carrier and the second carrier for transmitting PUCCH and / or UCI, and the UE can multiplex UCI onto the PUSCH on the first carrier and the second carrier. In other words, the UE can jointly select or determine the carrier and / or carrier bundle for transmitting PUCCH and / or UCI based on the RRC message used to configure the carrier or carrier bundle for transmitting PUCCH and / or UCI and the DCI used to schedule PUSCH.

[0196] In some implementations, the UE may determine the transmit power of the PUSCH and determine a first portion of the PUSCH for multiplexing UCI (and / or a first carrier group in which the first portion of the PUSCH for multiplexing UCI is located) based on the transmit power of the PUSCH.

[0197] In some implementations, the UE may determine a first power associated with the PUSCH and, based on the first power and / or a first power threshold, determine a first portion of the PUSCH used for multiplexing the UCI (and / or a first carrier group in which the first portion of the PUSCH used for multiplexing the UCI resides). The first power may be associated with the transmit power of the PUSCH on each of at least two uplink carriers. For example, the first power may be the sum of one or more of the calculated transmit powers of the PUSCH on each of at least two uplink carriers used for the PUSCH, or a weighted sum thereof, etc.

[0198] In this disclosure, P CMAX P can represent the total configured maximum UE output power of the UE. CMAX,c P can represent the maximum configured UE output power corresponding to the serving cell c. CMAX,f,c (or P) CMAX,c,fP can represent the configured maximum UE output power (in each slot) corresponding to carrier f of serving cell c. CMAX,b,c (or P) CMAX,c,b ) can represent the configured maximum UE output power (in each time slot) corresponding to the carrier bundle b in the serving cell c.

[0199] In this disclosure, P EMAX P can represent the total maximum allowed UE output power. EMAX,c This can represent the maximum allowed UE output power corresponding to the serving cell c. P EMAX and P EMAX c All of these can be configured through high-level parameters.

[0200] In some implementations, the UE may receive system information. The system information may include one or more first maximum allowed UE output powers (e.g., P) corresponding to one or more carriers and / or carrier bundles in the cell. EMAX,c,b P EMAX,c,f The fifth piece of information related to (etc.). The first power threshold can be calculated or determined from the one or more first maximum allowed UE output powers corresponding to the maximum allowed UE output power for at least two uplink carriers used for the first PUSCH. For example, the configured maximum UE output power (e.g., P) corresponding to the at least two uplink carriers used for the first PUSCH can be calculated based on the maximum allowed UE output power corresponding to the at least two uplink carriers used for the first PUSCH. CMAX,c,b P CMAX,c,f Then, a first power threshold is determined based on the configured maximum UE output power. For example, the configured maximum UE output power can be used as the first power threshold.

[0201] In some implementations, the first power threshold can be determined based on first information used for scheduling or configuring the PUSCH. Specifically, taking the first information as a DCI used for scheduling the PUSCH as an example, the DCI may include parameters indicating frequency domain resources used for the PUSCH. For example, the DCI may include parameters indicating carriers used for the PUSCH, or the DCI may include parameters indicating carrier bundles used for the PUSCH. In one example, the DCI schedules the PUSCH to be transmitted on carrier bundle b1 (or at least two carriers), where carrier bundle b1 includes carrier f1 and carrier f2. Then, the UE can determine the power threshold based on configuration information associated with carrier bundle b1 (e.g., P...).EMAX,c,b1 Determine P CMAX,c,b1 After that, the UE can be based on P. CMAX,c,b1 Determine the P corresponding to the serving cell c CMAX,c This is used as the first power threshold, and the first part of the PUSCH (or the carrier group in which the first part of the PUSCH is located) is determined based on this first power threshold.

[0202] In some implementations, the first information for scheduling or configuring the PUSCH may further include a second maximum allowed UE output power (e.g., P) corresponding to at least two uplink carriers used for the PUSCH. EMAX,c,b P EMAX,c,f The third information related to (etc.). The second maximum allowed UE output power can be used to determine the first configured maximum UE output power (e.g., P) corresponding to at least two uplink carriers used for PUSCH. CMAX,c,b P CMAX,c,f (etc.). In some implementations, the first power threshold may be determined based on the first configured maximum UE output power.

[0203] In some implementations, for a serving cell c with at least two uplink carriers, the UE is allowed to set its configured maximum UE output power P. CMAX,c In some implementations, when the UE is configured or scheduled to transmit PUSCH on carrier bundle b1, then P... CMAX,c It can be based on P CMAX,c,b1 Determined. In some implementations, when the UE is configured or scheduled to transmit PUSCH on carrier f1, then P... CMAX,c It can be based on P CMAX,c,f1 Determined. In some implementations, when the UE is configured or scheduled to transmit PUSCH on carriers f1 and f2, then P... CMAX,c It can be based on P CMAX,c,f1 and P CMAX,c,f2 The sum is determined.

[0204] In some implementations, the first power associated with the PUSCH can be determined based on parameters related to the target received power and parameters related to the amount of physical resources (e.g., RE / RB, etc.) and / or path loss of the PUSCH. In one example, where the first physical resources include multiple carriers, the first power associated with the PUSCH (e.g., P... PUSCH (f1)+P PUSCH (f2) etc. can be intermediate values ​​when calculating the transmission power of PUSCH, rather than the final calculated transmission power of PUSCH.

[0205] In some implementations, if the UE is configured with a serving cell c containing multiple uplink carriers, or if the UE transmits PUSCH on carrier f1 in serving cell c, the UE can determine the transmission power of PUSCH based on the following formula (1):

[0206]

[0207] Among them, P PUSCH (f1) represents the transmission power of PUSCH, and the frequency domain resources occupied by PUSCH are on the first carrier. P0 represents the maximum configured UE output power corresponding to carrier f1 in serving cell c, M represents the parameter related to the target received power, and P0+M represents the parameter related to the number of RBs and / or path loss of the PUSCH. P0+M can represent the first power related to the PUSCH.

[0208] In some implementations, if the UE is configured with a serving cell c containing multiple uplink carriers, or when the UE transmits PUSCH in a carrier bundle b1 in the serving cell c, wherein the carrier bundle b1 includes at least two uplink carriers (hereinafter, two carriers (carrier f1 and carrier f2) are used as an example), the UE can determine the transmission power of the portion of the PUSCH on carrier f1 based on the following equation (2):

[0209]

[0210] The UE can determine the transmission power of the portion of PUSCH on carrier f2 based on the following equation (3):

[0211]

[0212] Among them, P PUSCH (f1) represents the transmission power of the portion of PUSCH on carrier f1. P represents the maximum configured UE output power corresponding to carrier f1 in serving cell c, P0 represents a parameter related to the target received power of carrier f1, and M represents a parameter related to the number of RBs and / or path loss corresponding to the portion of PUSCH on carrier f1; P PUSCH (f2) represents the transmission power of the portion of PUSCH on carrier f2. P0' represents the maximum configured UE output power corresponding to carrier f2 in serving cell c, P0' represents a parameter related to the target received power of carrier f2, and M' represents a parameter related to the number of RBs and / or path loss corresponding to the portion of PUSCH on carrier f2. The sum of P0+M and P0'+M' can represent the first power related to PUSCH.

[0213] In some implementations, if the UE is configured with a serving cell c containing multiple uplink carriers, or when the UE transmits PUSCH in a carrier bundle b1 within the serving cell c, wherein the carrier bundle b1 includes at least two uplink carriers, the UE can determine the transmission power of the PUSCH based on the following formula (4):

[0214]

[0215] Among them, P PUSCH (b1) represents the transmission power of PUSCH. The frequency domain resources occupied by PUSCH are on carrier bonding b1. P0 represents the maximum configured UE output power corresponding to carrier bundle b1 in serving cell c, P0 represents the parameter related to the target received power of carrier bundle b1, and M represents the parameter related to the number of RBs and / or path loss of PUSCH. P0+M can represent the first power related to PUSCH.

[0216] In some implementations, the UE may determine or select a first portion of the PUSCH (and / or a first carrier group in which the first portion of the PUSCH is located) based on a first power associated with the PUSCH.

[0217] In some implementations, if the UE is configured with a serving cell c containing multiple uplink carriers, or when the UE transmits PUSCH in a carrier bundle b1 within the serving cell c, wherein the carrier bundle b1 includes at least two uplink carriers, the UE can determine the transmission power of the PUSCH based on the following formula (5):

[0218]

[0219] Furthermore, the UE needs to allocate power so that as well as

[0220] Among them, P PUSCH (b1) represents the transmission power of PUSCH. The frequency domain resources occupied by PUSCH are on carrier bonding b1. This represents the maximum configured UE output power corresponding to carrier binding b1 in serving cell c; P PUSCH (f1) = P0 + M, P PUSCH (f2) = P0' + M'; P PUSCH (f1) represents the transmit power of the portion of the PUSCH on carrier f1, P0 represents a parameter related to the target receive power of the first carrier, and M represents a parameter related to the number of RBs and / or path loss corresponding to the portion of the PUSCH on carrier f1; P PUSCH(f2) represents the transmit power of the portion of the PUSCH on carrier f2, P0' represents a parameter related to the target receive power of the second carrier, and M' represents a parameter related to the number of RBs and / or path loss corresponding to the portion of the PUSCH on carrier f2. PUSCH (f1)+P PUSCH (f2) can represent the first power associated with PUSCH.

[0221] In some implementations, the first condition may include one or more of the following:

[0222] ·

[0223] ·

[0224] · and

[0225] When the first condition is met, the UE can reduce the transmission power of the portion of the PUSCH on carrier f1 and / or carrier f2, such that the following three conditions are met:

[0226] ·

[0227] ·

[0228] ·

[0229] Here, the scaling factors (also called power scaling factors, power reduction factors, or any other related terms) w(f1) and w(f2) may be equal or unequal. After power reduction, the actual transmit power of the portion of carrier f1 occupied by PUSCH is w(f1)·P PUSCH (f1), the actual transmission power of the portion of carrier f2 occupied by PUSCH is w(f2)·P PUSCH (f2).

[0230] Figure 8 An example of a UE reducing its transmit power according to an embodiment of this disclosure is shown.

[0231] like Figure 8 As shown, the transmit power on carrier f2 exceeds the maximum UE output power configured for carrier f2 (e.g., P). PUSCH (f2)>P CMAX,c,f2The UE can scale the transmit power on carrier f1 and / or carrier f2 such that the transmit power on carrier f2 does not exceed the transmit power configured for the UE on carrier f2. That is, the power scaling factor can be based on a power threshold corresponding to each of the at least two uplink carriers used to transmit the PUSCH (e.g., ...). Figure 8 P shown CMAX, c,f1 and P CMAX, c, f2, etc.) and the transmission power of the uplink transmission on each of the at least two uplink carriers (e.g., such as Figure 8 The values ​​P(f1) and P(f2), etc., shown are determined. In the example corresponding to the figure below, w(f1) and w(f2) are not equal.

[0232] In some implementations, the UE can be based on the power scaling factor w(f) n The first portion of the PUSCH (and / or the first carrier group in which the first portion of the PUSCH resides) is determined. Specifically, the first carrier group in which the first portion of the PUSCH resides may include a sixth carrier among all carriers used for the PUSCH. The sixth carrier may include at least one of the following:

[0233] • To ensure that the actual transmission power does not exceed the maximum transmission power allowed by the UE, the carrier with the smallest power reduction ratio (e.g., the largest corresponding power scaling factor) is used;

[0234] • To ensure that the actual transmission power does not exceed the maximum transmission power allowed for the UE, the first N carriers with the smallest power reduction ratio are selected;

[0235] Where N can be predefined in the protocol or determined based on higher-level parameters. N can be a positive integer.

[0236] In one example, such as Figure 8 As shown, w(f1) = 1, w(f2) < 1. The UE can select the carrier with the largest corresponding power scaling factor (e.g., carrier f1) and use the portion of the PUSCH on that carrier as the first part of the PUSCH. For example, Figure 9 An example procedure is shown for a UE to select the first part of the PUSCH for multiplexing UCI according to an embodiment of this disclosure. Figure 9 As shown, the UE can select the carrier f1 with the largest power scaling factor as the first carrier group in which the first part of the PUSCH is located.

[0237] In some implementations, the UE can be based on w(f) n Determine the first part of the PUSCH and / or the first carrier group in which the first part of the PUSCH is located. Figure 10Another example procedure is shown for a UE to select the first part of the PUSCH for multiplexing UCI according to an embodiment of this disclosure. For example... Figure 10 As shown, in one case, w(f1) = w(f2) > w(f3), so the UE can select carrier f1 and carrier f2 as the first carrier group and multiplex UCI in the PUSCH portion on carrier f1 and carrier f2.

[0238] The advantage of this design is that the UE can select the PUSCH section with a relatively small power reduction ratio to reuse the UCI, thereby ensuring the reliability of uplink control information.

[0239] In some implementations, the UE may determine the first portion of the PUSCH (and / or the first carrier group in which the first portion of the PUSCH resides) based on the path loss of the downlink channel and / or downlink carrier corresponding to each of at least two uplink carriers used for the PUSCH. For example, the UE may determine the first portion of the PUSCH based on the path loss of the downlink carrier associated with the uplink carrier. In one example, the PUSCH may occupy k uplink carriers, namely f1, f2, ..., f k The UE can base its decisions on k carriers associated with one or more of the k uplink carriers. DL The UE determines the first part of the PUSCH using k downlink carriers. For example, when there is a one-to-one correspondence between uplink and downlink carriers, the UE can determine one or more first downlink carriers from the k downlink carriers, and then determine the uplink carriers associated with those one or more first downlink carriers based on those one or more first downlink carriers. The first part of the PUSCH is the portion of the PUSCH on the one or more uplink carriers associated with those one or more first downlink carriers. In some examples, the UE can multiplex uplink control information in the first part of the PUSCH. In some implementations, the first carrier group containing the first part of the PUSCH may include a seventh carrier among all carriers used for the PUSCH. The seventh carrier may include at least one of the following:

[0240] • The corresponding downlink carrier with the maximum path loss

[0241] • The corresponding downlink carrier has the first M1 carriers with the maximum path loss.

[0242] • The corresponding downlink carrier has the minimum path loss.

[0243] • The corresponding downlink carrier has the first M2 minimum path loss carriers.

[0244] • The corresponding downlink carrier has the lowest frequency carrier.

[0245] • The corresponding downlink carrier has the first K1 lowest frequency carriers.

[0246] • The corresponding downlink carrier has the highest frequency carrier.

[0247] The corresponding downlink carrier has the first K2 highest frequency carriers, where M1, M2, K1, and K2 can be predefined by the protocol or determined based on higher-layer parameters. M1, M2, K1, and K2 can be positive integers.

[0248] In some implementations, the UE can be configured to partially compensate for path loss on one or more carrier pairs. Therefore, in some examples, the UE can determine the first portion of the PUSCH used for multiplexing the UCI (and / or the first carrier group containing the first portion of the PUSCH) based on path loss compensation. In some implementations, the first carrier group containing the first portion of the PUSCH may include an eighth carrier out of all carriers used for that PUSCH. The eighth carrier may include at least one of the following:

[0249] The corresponding downlink carrier has the maximum α(f) i )·PL(f i ) carrier

[0250] The corresponding downlink carrier has the first L1 largest α(f) i )·PL(f i ) carrier

[0251] The corresponding downlink carrier has a minimum α(f) i )·PL(f i ) carrier

[0252] The corresponding downlink carrier has the first L2 minimum α(f) values. i )·PL(f i ) carrier

[0253] Wherein, L1 and L2 can be predefined by the protocol or determined based on higher-layer parameters. L1 and L2 can be positive integers. Wherein, α(f i () is determined based on higher-level parameters, and is related to the carrier f i Parameters related to path loss compensation; PL(f i ) represents carrier f i Path loss. α(f) i )·PL(f i ) can represent the relationship with carrier f i Corresponding path loss compensation.

[0254] In some implementations, the UE can select the first portion of the PUSCH (and / or the first carrier group in which the first portion of the PUSCH resides) based on the target received power. For example, the UE can determine the first portion of the PUSCH based on the target received power associated with the uplink carrier. In one example, the PUSCH can occupy k uplink carriers, namely f1, f2, ..., f k In some examples, the UE can multiplex uplink control information in the first part of the PUSCH. In some implementations, the first carrier group containing the first part of the PUSCH may include the ninth carrier among all carriers used for that PUSCH. The ninth carrier may include at least one of the following:

[0255] • Carrier with minimum target received power

[0256] • Carriers with the first J1 minimum target received power

[0257] • Carrier with maximum target received power

[0258] • A carrier with the top J2 maximum target received power, wherein J1 and J2 can be predefined by the protocol or determined based on higher-layer parameters. J1 and J2 can be positive integers.

[0259] In some implementations, the UE can select the first part of the PUSCH (and / or the first carrier group in which the first part of the PUSCH is located) based on the number of REs / RBs occupied by the PUSCH on each carrier. In one example, the PUSCH can occupy k uplink carriers, namely f1, f2, ..., f k In some examples, the UE can multiplex uplink control information in the first part of the PUSCH. In some implementations, the first carrier group containing the first part of the PUSCH may include the tenth carrier among all carriers used for that PUSCH. The tenth carrier may include at least one of the following:

[0260] • Carriers with the smallest number of REs used for PUSCH

[0261] • The carrier with the largest number of REs used for PUSCH

[0262] • Carriers with the smallest number of RBs used for PUSCH

[0263] • The carrier with the largest number of RBs used for PUSCH

[0264] In some implementations, the UE can select the first part of the PUSCH (and / or the first carrier group in which the first part of the PUSCH resides) based on other parameters. For example, the UE can select the first part of the PUSCH based on parameters such as modulation and coding scheme (MCS), power control commands, etc. In one example, the PUSCH can occupy k uplink carriers, namely f1, f2, ..., f k In some examples, the UE can multiplex uplink control information in the first part of the PUSCH. In some implementations, the first carrier group containing the first part of the PUSCH may include the eleventh carrier among all carriers used for that PUSCH. The eleventh carrier may include at least one of the following:

[0265] PUSCH is the carrier with the largest MCS on this carrier.

[0266] PUSCH has the smallest MCS on this carrier.

[0267] • PUSCH is the carrier with the maximum power control adjustment state on that carrier.

[0268] • PUSCH is the carrier with the minimum power control adjustment state on that carrier.

[0269] In some implementations, if the UE is configured with a serving cell c containing multiple uplink carriers, or when the UE transmits PUSCH in a carrier bundle b1 in the serving cell c, wherein the carrier bundle b1 includes at least two uplink carriers, the UE can determine the transmission power of the PUSCH based on the following formula (6) or formula (7):

[0270]

[0271] or

[0272]

[0273] Among them, P' PUSCH (b1) is determined based on the target received power of the PUSCH on carrier bundle b1, the number of RE / RBs allocated to the PUSCH on carrier bundle b1, and the path loss of the carrier corresponding to carrier bundle b1.

[0274] In some implementations, if the first transmit power (e.g., the first power associated with the PUSCH) calculated based on the number of REs / RBs occupied by the PUSCH is greater than the configured maximum transmit power, the UE may reduce (or decrease) the transmit power.

[0275] In some implementations, when the UE is configured or scheduled to transmit PUSCH on n carriers from c1 to cn, the transmit power corresponding to the nth carrier is P. n .

[0276] In some implementations, if the total UE transmit power for transmitting PUSCH in the first cell (serving cell c) (e.g., transmit power calculated based on the number of REs / RBs occupied by the PUSCH) (e.g., the first power associated with the PUSCH) exceeds a first power threshold, the UE can reduce the transmit power of the PUSCH, for example, the transmit power on the second carrier group. In some implementations, the PUSCH occupies two or more uplink carriers. n The linear value of the UE transmit power of the PUSCH on the nth carrier, when At this time, the UE can reduce the transmit power of the second carrier group, so that

[0277] In some implementations, the second carrier group may include at least one of the following:

[0278] • The third carrier group includes all carriers used for PUSCH;

[0279] • The fourth carrier group includes all carriers used for PUSCH except the anchor carrier;

[0280] • The fifth carrier group includes all carriers used for PUSCH except for the default carrier, where the default carrier is configured by higher-layer parameters;

[0281] • The sixth carrier group includes all carriers used for PUSCH except for the carrier with the smallest (or largest) index.

[0282] • The seventh carrier group includes all carriers used for PUSCH except for the lowest (or highest) frequency carrier;

[0283] • The eighth carrier group includes all carriers used for PUSCH except those used for PUCCH;

[0284] • The ninth carrier group includes all carriers used for PUSCH except for the third carrier, where the third carrier is the carrier with the smallest (or largest) index among the carriers used for PUSCH;

[0285] • The tenth carrier group includes all carriers used for PUSCH except for the fourth carrier, where the fourth carrier is the lowest (or highest) frequency carrier used for PUSCH.

[0286] • The eleventh carrier group includes all carriers used for PUSCH except for the fifth carrier, wherein the fifth carrier is used to transmit hybrid automatic repeat request feedback (e.g., HARQ-ACK);

[0287] • The twelfth carrier group includes all carriers used for PUSCH except for the sixth carrier as described above;

[0288] • The thirteenth carrier group includes all carriers used for PUSCH except for the seventh carrier as described above;

[0289] • The fourteenth carrier group includes all carriers used for PUSCH except for the eighth carrier as described above;

[0290] • The fifteenth carrier group includes all carriers used for PUSCH except for the ninth carrier as described above;

[0291] • The sixteenth carrier group includes all carriers used for PUSCH except for the tenth carrier as described above;

[0292] • The seventeenth carrier group includes all carriers used for PUSCH except for the eleventh carrier as described above.

[0293] In some implementations, P in the above scheme CMAX,c It can be replaced with P CMAX,c,b1 In this context, carrier bundle b1 includes n carriers, from carrier c1 to carrier cn. In this paper, a carrier group refers to a set of one or more carriers. That is, a carrier group can include one or more uplink carriers.

[0294] In some implementations, to ensure that the sum of the UE's power on all uplink carriers used for PUSCH does not exceed a first power threshold... The UE needs to reduce the transmit power of the PUSCH (e.g., the transmit power on the second carrier group as described above). If the reduction in the transmit power of the PUSCH exceeds a second threshold, the UE may perform at least one of the following:

[0295] • The UE is not required to transmit on any carrier;

[0296] • The UE is not required to transmit on all carriers used for PUSCH;

[0297] • The UE is not required to transmit on a non-anchored carrier;

[0298] • The UE is not required to transmit on carriers other than the default carrier, which is configured by higher-layer parameters;

[0299] • The UE is not required to transmit using the smallest (or largest) carrier or carrier bundle among the carriers other than the one corresponding to the PUSCH;

[0300] • The UE is not required to transmit on the lowest (or highest) frequency carrier or carrier bundle among the carriers other than the carrier corresponding to the PUSCH;

[0301] • The UE is not required to transmit on any carrier other than the one used for PUCCH or carrier bundles;

[0302] • The UE is not required to transmit on any carrier other than the third carrier, which is the carrier with the smallest (or largest) index among the carriers used for PUCCH;

[0303] • The UE is not required to transmit on any carrier other than the fourth carrier, which is the lowest (or highest) frequency carrier among the carriers used for PUCCH;

[0304] • The UE is not required to transmit on any carrier other than the fifth carrier, which is the carrier used to transmit HARQ-ACK;

[0305] • The UE is not required to transmit on any carrier other than the sixth carrier;

[0306] • The UE is not required to transmit on any carrier other than the seventh carrier;

[0307] • The UE is not required to transmit on any carrier other than the eighth carrier;

[0308] • The UE is not required to transmit on any carrier other than the ninth carrier;

[0309] • The UE is not required to transmit on any carrier other than the tenth carrier;

[0310] • The UE is not required to transmit on any carrier other than the eleventh carrier.

[0311] The second threshold can be predefined by the protocol or configured by higher-level parameters.

[0312] In other words, if the reduction in the transmission power of PUSCH (e.g., the reduction in transmission power on the second carrier group as described above) exceeds the second threshold, the UE may not transmit PUSCH on the second carrier group (or one or more of the fourth to seventeenth carrier groups as described above) (even if it is configured or scheduled to be transmitted on it).

[0313] In some implementations, if the first transmit power calculated based on the number of REs / RBs occupied by the PUSCH is greater than the configured maximum transmit power, the UE may discard the second portion of the PUSCH. In some implementations, the carrier containing the second portion of the PUSCH may be one or more carriers in a second carrier group. In some implementations, the second carrier group may include at least one of the following:

[0314] • The third carrier group includes all carriers used for PUSCH;

[0315] • The fourth carrier group includes all carriers used for PUSCH except the anchor carrier;

[0316] • The fifth carrier group includes all carriers used for PUSCH except for the default carrier, where the default carrier is configured by higher-layer parameters;

[0317] • The sixth carrier group includes all carriers used for PUSCH except for the carrier with the smallest (or largest) index.

[0318] • The seventh carrier group includes all carriers used for PUSCH except for the lowest (or highest) frequency carrier;

[0319] • The eighth carrier group includes all carriers used for PUSCH except those used for PUCCH;

[0320] • The ninth carrier group includes all carriers used for PUSCH except for the third carrier, where the third carrier is the carrier with the smallest (or largest) index among the carriers used for PUSCH;

[0321] • The tenth carrier group includes all carriers used for PUSCH except for the fourth carrier, where the fourth carrier is the lowest (or highest) frequency carrier used for PUSCH.

[0322] • The eleventh carrier group includes all carriers used for PUSCH except for the fifth carrier, wherein the fifth carrier is used to transmit hybrid automatic repeat request feedback (e.g., HARQ-ACK);

[0323] • The twelfth carrier group includes all carriers used for PUSCH except for the sixth carrier as described above;

[0324] • The thirteenth carrier group includes all carriers used for PUSCH except for the seventh carrier as described above;

[0325] • The fourteenth carrier group includes all carriers used for PUSCH except for the eighth carrier as described above;

[0326] • The fifteenth carrier group includes all carriers used for PUSCH except for the ninth carrier as described above;

[0327] • The sixteenth carrier group includes all carriers used for PUSCH except for the tenth carrier as described above;

[0328] • The seventeenth carrier group includes all carriers used for PUSCH except for the eleventh carrier as described above.

[0329] In some implementations, one or more carriers in the second carrier group (e.g., one or more carrier groups from the third to the seventeenth carrier group, or one or more carriers in each carrier group) may also have any further priority order for reducing transmission power or for dropping, which is not limited in this disclosure.

[0330] Figure 11 A schematic diagram showing a UE transmitting information indicating the carrier to which the UCI is multiplexed, according to an embodiment of the present disclosure.

[0331] In some implementations, such as Figure 11 As shown, the UE can send fourth information before sending the UCI. This fourth information can be used to indicate the resources occupied by the UCI. For example, the fourth information may include information related to the carrier multiplexed by the UCI, such as the index or identifier of the carrier multiplexed by the UCI.

[0332] In one example, the fourth information may include a parameter indicating the carrier to which the UCI is multiplexed. In one example, this parameter may include R bits. In one example, when the number of carriers occupied by the PUSCH is 1, R equals 0; in one example, when the number of carriers occupied by the PUSCH is 2, R equals 1, and when the value of the parameter is 0, it indicates that the UCI is multiplexed on carrier f1, and when the value of the parameter is 1, it indicates that the UCI is multiplexed on carrier f2; in one example, when the number of carriers occupied by the PUSCH is 3, R equals 3, and when the value of the parameter is 001, it indicates that the UCI is multiplexed on carrier f1, when the value of the parameter is 010, it indicates that the UCI is multiplexed on carrier f2, when the value of the parameter is 100, it indicates that the UCI is multiplexed on carrier f3, and when the value of the parameter is 011, it indicates that the UCI is multiplexed on both carriers f1 and f2.

[0333] Figure 12 Another schematic diagram is shown showing a UE transmitting information indicating the carrier to which the UCI is multiplexed, according to an embodiment of this disclosure.

[0334] In some implementations, such as Figure 12 As shown, the UE transmits a UCI. The UCI may include fourth information. The fourth information can be used to indicate the resources occupied by the UCI. For example, the fourth information may include information related to the carrier to which the UCI is multiplexed, such as the index or identifier of the carrier to which the UCI is multiplexed.

[0335] In other words, the fourth piece of information can be sent before the UCI or included in the UCI.

[0336] In some implementations, UCI can be multiplexed onto PUSCH, which can occupy at least two uplink carriers. Figure 13 An example of multiplexing UCI on a PUSCH according to an embodiment of this disclosure is shown. For example... Figure 13 As shown, the first PUSCH can occupy carrier f1, carrier f2, and carrier f3 (e.g., carrier bundle b2). UCI can be multiplexed onto the portions of the first PUSCH on carrier f1, carrier f2, and carrier f3.

[0337] More specifically, the method for multiplexing UCI to PUSCH according to embodiments of this disclosure may include one or more of the following operations: mapping HARQ-ACK bits in UCI to a first RE set, or mapping HARQ-ACK bits to a subset of the first RE set; mapping CSI part 1 to a second RE set, or mapping CSI part 1 to a subset of the second RE set; mapping CSI part 2 to a third RE set, or mapping CSI part 2 to a subset of the third RE set. In some implementations, CSI part 1 and CSI part 2 may be treated as a whole without further distinction.

[0338] Figure 14 Another example of multiplexing UCI on PUSCH according to an embodiment of this disclosure is shown.

[0339] In some implementations, such as Figure 14 As shown, the first RE set can be the set of REs occupied by PUSCH on the eighteenth carrier group; the second RE set can be the set of REs occupied by PUSCH on carriers other than the eighteenth carrier group; the third RE set can be the set of REs occupied by PUSCH on carriers other than the eighteenth carrier group, excluding the second RE set.

[0340] In some implementations, the eighteenth carrier group may include one or more carriers in the carrier group containing the first portion of the PUSCH (e.g., the first carrier group as described above).

[0341] The RE set here is just an example; the RE set can also be any other set of physical resources.

[0342] Figure 15 Another example of multiplexing UCI on PUSCH according to an embodiment of this disclosure is shown.

[0343] In some implementations, such as Figure 15 As shown, the first RE set can be the set of REs occupied by PUSCH on the eighteenth carrier group; the second RE set can be the set of REs occupied by PUSCH other than the first RE set; the third RE set can be the set of REs occupied by PUSCH other than the first RE set and the second RE set.

[0344] Figure 16 Another example of multiplexing UCI on PUSCH according to an embodiment of this disclosure is shown.

[0345] In some implementations, such as Figure 16 As shown, the UE first maps HARQ-ACK, for example, mapping the HARQ-ACK bits to portions of the PUSCH on one or more carriers in the eighteenth carrier group, starting from the symbol following the first symbol occupied by the DMRS. The UE then maps CSI, for example, mapping the CSI to portions of the corresponding PUSCH on all carriers occupied by the PUSCH, starting from the first symbol of the PUSCH.

[0346] Figure 17 Another example of multiplexing UCI on PUSCH according to an embodiment of this disclosure is shown.

[0347] In some implementations, such as Figure 17 As shown, the UE first maps HARQ-ACK, for example, mapping the HARQ-ACK bits to a portion of the PUSCH on each carrier in the eighteenth carrier group, starting from the symbol following the first symbol occupied by the DMRS. The UE then maps CSI, for example, mapping the CSI to the corresponding portions of the PUSCH on all carriers occupied by the PUSCH, starting from the first symbol of the PUSCH. It should be noted that the HARQ-ACK bits mapped on each carrier can be the same (e.g., duplicated HARQ-ACK).

[0348] The advantage of this design approach is that it ensures the reliability of HARQ-ACK transmission. When the various parts of the PUSCH are not discarded by the UE, the HARQ-ACK bits corresponding to multiple carriers can be combined by the base station, enhancing reliability. Specifically, when the PUSCH transmission power exceeds the maximum transmission power configured for the UE, the UE may reduce the transmission power for different parts of the PUSCH, or the UE may discard some parts of the PUSCH. This design ensures that the HARQ-ACK information in the uplink control information exists on every carrier. Even if the UE reduces the transmission power or discards some parts of the PUSCH, the HARQ-ACK information can still be decoded, thus guaranteeing the reliability of the HARQ-ACK information.

[0349] Figure 18 Another example of multiplexing UCI on PUSCH according to an embodiment of this disclosure is shown.

[0350] In some implementations, such as Figure 18 As shown, the UE receives a PDCCH in the N1th time unit (e.g., a time slot), which includes downlink control information (DCI). The DCI schedules the UE to transmit a first PUSCH in the N1+d+kth time unit, wherein the first PUSCH occupies at least two uplink carriers (e.g., carrier 1, carrier 2, and carrier 3). The UE receives a PDSCH in the N1+dth time unit, and the UE is configured or instructed to report a HARQ-ACK corresponding to the PDSCH in k time units following the time unit in which the PDSCH is located.

[0351] In some implementations, the UE multiplexes the encoded uplink control information bits in the PUSCH, the physical resources of which are determined based on DCI or configuration information related to the CG PUSCH. When k is greater than or equal to a first quantity (e.g., a third threshold), the UE multiplexes the encoded uplink control information bits in a first portion of the PUSCH. This first quantity is determined based on higher-layer parameters, or it may be predefined by the protocol. When k is less than the first quantity, the UE multiplexes the encoded uplink control information bits in all portions of the PUSCH. Alternatively, if portions of the PUSCH on some carriers are dropped or their transmission power is reduced, when k is greater than or equal to the first quantity (e.g., the third threshold), the UE can remultiplex the UCI into portions of the PUSCH that were not dropped or had their transmission power reduced; when k is less than the first quantity, the UE maintains the previous multiplexing of the UCI into all portions of the PUSCH.

[0352] The advantage of this design is that the UE can calculate the transmission power of the PUSCH before multiplexing the UCI to the PUSCH, and determine that when the transmission power of the PUSCH exceeds the maximum power allowed by the UE, the UE can transmit the UCI in an appropriate manner, thereby improving the transmission reliability of the UCI.

[0353] Figure 19 Another example of multiplexing UCI on PUSCH according to an embodiment of this disclosure is shown.

[0354] In some implementations, such as Figure 19 As shown, the UE receives a PDSCH in the N1th time unit, and the UE is configured or instructed to report a HARQ-ACK corresponding to the PDSCH in the (d+k)th time unit following the time unit where the PDSCH is located. The UE receives a PDCCH in the (N1+d)th time unit (e.g., a slot), the PDCCH including downlink control information (DCI). The DCI schedules the UE to transmit a first PUSCH in the (N1+d+k)th time unit, wherein the first PUSCH occupies at least two uplink carriers (e.g., carrier 1, carrier 2, and carrier 3). When k is greater than or equal to a second quantity (e.g., a fourth threshold), the UE multiplexes the encoded uplink control information bits in the first part of the PUSCH. The second quantity is determined based on higher-layer parameters, or it is predefined by the protocol; when k is less than the second quantity, the UE multiplexes the encoded uplink control information bits in all parts of the PUSCH. Alternatively, if parts of the PUSCH on some carriers are dropped or the transmission power is reduced, when k is greater than or equal to a first number (e.g., a third threshold), the UE can reuse the UCI in the parts of the PUSCH that were not dropped or whose transmission power was not reduced; when k is less than the first number, the UE still retains the previous UCI reused in all parts of the PUSCH.

[0355] The advantage of this design is that the UE can calculate the transmission power of the PUSCH before multiplexing the UCI to the PUSCH, and determine that when the transmission power of the PUSCH exceeds the maximum power allowed by the UE, the UE can transmit the UCI in an appropriate manner, thereby improving the transmission reliability of the UCI.

[0356] The embodiments of this disclosure primarily describe exemplary methods using the UE side as an example. It should be understood that the embodiments of this disclosure also include any base station-side methods corresponding to the UE method, which will not be described redundantly below.

[0357] It should be understood that, depending on the application scenario, the various example schemes, aspects, methods, steps, processes, etc. shown above in conjunction with the accompanying drawings can be implemented individually or in any combination, and this document does not impose any restrictions.

[0358] Next, Figure 20 A flowchart of a method 2000 performed by a user equipment (UE) in a wireless communication system according to an embodiment of this disclosure is shown.

[0359] like Figure 20 As shown, a method 2000 performed by a user equipment (UE) in a wireless communication system according to an embodiment of this disclosure may include: in step S2001, receiving first information for scheduling or configuring uplink transmission, wherein the first information includes second information related to first physical resources for the uplink transmission, wherein the first physical resources include physical resources in at least two uplink carriers in a cell; in step S2002, multiplexing uplink control information (UCI) in a first portion of the uplink transmission, wherein the first portion of the uplink transmission is located in a first carrier group including one or more carriers of the at least two uplink carriers, wherein the first carrier group is determined based on a first power, wherein the first power is associated with the transmission power of the uplink transmission on each of the at least two uplink carriers; and in step S2003, transmitting the first portion of the uplink transmission.

[0362] According to embodiments of this disclosure, the first carrier group includes at least one of the following from the at least two uplink carriers: an uplink carrier having the top N maximum power scaling factors, wherein the power scaling factors are determined based on a power threshold corresponding to each of the at least two uplink carriers and the transmit power of the uplink transmission on each of the at least two uplink carriers; an uplink carrier having the top M minimum path loss corresponding to the downlink carrier; an uplink carrier having the top K lowest frequencies corresponding to the downlink carrier; an uplink carrier having the top L minimum path loss compensation corresponding to the downlink carrier; an uplink carrier having the top J minimum target receive power; an uplink carrier with the minimum number of physical resources for the uplink transmission; an uplink carrier with the maximum number of physical resources for the uplink transmission; an uplink carrier having the maximum modulation and coding scheme (MCS) on which the uplink transmission is carried; an uplink carrier having the minimum MCS on which the uplink transmission is carried; an uplink carrier having the maximum power control adjustment state on which the uplink transmission is carried; and an uplink carrier having the minimum power control adjustment state on which the uplink transmission is carried, wherein N, M, K, L, and J are positive integers.
