[0003] A 5G communication system is implemented in a higher frequency (millimeter wave, mmWave) band, such as 60 GHz band, to accomplish a higher data rate. To mitigate a propagation loss of radio waves and increase a transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam forming, large scale antenna techniques are discussed in 5G communication systems.

[0004] In addition, in 5G communication systems, development for system network improvement is under way based on advanced small cells, cloud radio access networks (RANs), ultra-dense networks, a device to device (D2D) communication, a wireless backhaul, a mobile network, a cooperative communication, coordinated multi-points (CoMP), reception-end interference cancellation and the like.

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

Figure 1 The embodiment of the wireless network 100 shown is for illustrative purposes only. Other embodiments of the wireless network 100 can be used without departing from the scope of this disclosure.

[0064] Wireless network 100 includes gNodeB (gNB) 101, gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one Internet Protocol (IP) network 130 (such as the Internet, a proprietary IP network, or other data network).

[0065] Depending on the network type, other well-known terms such as "base station" or "access point" can be used instead of "gNodeB" or "gNB".

[0066] gNB 102 provides wireless broadband access to network 130 to multiple first user equipments (UEs) within its coverage area 120. The multiple first UEs include: UE 111, which may be located in a small business (SB); UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi hotspot (HS); UE 114, which may be located in a first residence (R); UE 115, which may be located in a second residence (R); and UE 116, which may be a mobile device (M), such as a cellular phone, wireless laptop computer, wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 to multiple second UEs within its coverage area 125. The multiple second UEs include UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 are capable of communicating with each other and with UEs 111-116 using 5G, LTE, LTE-A, WiMAX, or other advanced wireless communication technologies.

[0067] The dashed lines indicate the approximate extent of coverage areas 120 and 125, which are shown as approximately circular for illustrative and explanatory purposes only. It should be clearly understood that coverage areas associated with the gNB, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0068] As described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of this disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook design and architecture for systems having 2D antenna arrays.

[0069] although Figure 1 An example of a wireless network 100 is shown, but it is possible to... Figure 1 Various modifications can be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Furthermore, gNB 101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. In addition, gNBs 101, 102, and / or 103 can provide access to other or additional external networks (such as external telephone networks or other types of data networks).

[0070] Figure 2a and Figure 2bExample wireless transmit and receive paths according to this disclosure are shown. In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102), while receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that receive path 250 can be implemented in a gNB, and transmit path 200 can be implemented in a UE. In some embodiments, receive path 250 is configured to support codebook design and structure for a system having a 2D antenna array as described in embodiments of this disclosure.

[0071] The transmit path 200 includes a channel coding and modulation block 205, a serial-to-parallel (S-to-P) block 210, an N-point inverse fast Fourier transform (IFFT) block 215, a parallel-to-serial (P-to-S) block 220, a cyclic prefix addition block 225, and an up-converter (UC) 230. The receive path 250 includes a down-converter (DC) 255, a cyclic prefix removal block 260, a serial-to-parallel (S-to-P) block 265, an N-point fast Fourier transform (FFT) block 270, a parallel-to-serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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 2b At 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.

[0076] Furthermore, although the description uses FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of this disclosure. Other types of transforms, such as the Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions, can be used. It should be understood that for DFT and IDFT functions, the value of variable N can be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N can be any integer that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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).

[0085] 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.

[0086] Figure 3bAn 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] although Figure 3b An example of gNB 102 is shown, but more can be found on... 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).

[0096] Exemplary embodiments of this disclosure are further described below with reference to the accompanying drawings.

[0097] 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.

[0098] The agreement in this article can be understood as either a direct agreement or an indirect agreement (e.g., clarifying the mapping relationship through signaling interaction).

[0099] The specific embodiments of the present invention are described below.

[0100] In communication networks, Power Class (PC) is a common way to classify User Equipment (UE) based on its transmit power capability. UEs with different power classes have different transmit power capabilities, meaning their maximum transmit power varies. Among the different power classes, Power Class 3 (PC3) is the default UE power class. UEs that support transmit power higher than PC3 are called High Power User Equipment (HPUE).

[0101] For user equipment (UE) used close to the human body, its transmission power is subject to restrictions imposed by laws and regulations in various countries and regions. Specific Absorption Rate (SAR) and Absorbed Power Density (APD) or Incident Power Density (IPD) are commonly used metrics to measure the electromagnetic radiation impact of UE transmission power on the human body. To keep the electromagnetic radiation impact of the UE within a safe range, and in other words, to meet the regulatory requirements of the aforementioned metrics, the UE's transmission power often needs to be reduced.

[0102] Non-terrestrial networks (NTNs) are a new type of network that requires the UE to transmit uplink power from the ground to communicate with satellites at different orbital altitudes. Due to the longer communication distance, the uplink power required is higher than that of other terrestrial networks (TNs). Therefore, applying HPUEs in NTN scenarios is an important solution for improving and strengthening the uplink of NTN networks.

[0103] At this point, the conflict between HPUE's high transmission power and electromagnetic radiation regulations aimed at protecting user safety is a problem that urgently needs to be solved.

[0104] Various embodiments of this disclosure provide a method executed by a user equipment (UE) in a communication system, comprising: sending first information to a network side, the first information including: first uplink time ratio information and / or fourth information, wherein the first uplink time ratio information is associated with the maximum uplink transmission time ratio corresponding to the highest power level supported by the UE; the fourth information is associated with the UE having the ability to enter a first state, wherein in the first state, the UE does not perform uplink transmission; receiving second information or sixth information from the network side, wherein the second information includes information associated with the second uplink time ratio information of the UE, and the sixth information includes configuration information related to UE transmit power backoff; determining a transmit power backoff value of the UE based on the first information, or based on the first uplink time ratio information and the second uplink time ratio information, or based on the sixth information.

[0105] The various embodiments of this disclosure provide a method for determining the transmit power backoff value of a user equipment (UE) in a communication system. This method is not a fixed power backoff value corresponding to a power level, but a transmit power backoff value determined based on first information, or based on first and second information, or based on first and sixth information (the transmit power backoff value can also be 0, as described in the following embodiments). This method is more flexible, enabling the HPUE to maintain the transmit power corresponding to its high power level as much as possible, while ensuring that the HPUE complies with electromagnetic radiation regulations.

[0106] Step S401: The UE sends the first information to the network side.

[0107] The first information should include the highest power level supported by the UE, and the time ratio information of the maximum uplink transmission corresponding to that highest power level (also referred to as the first time ratio information, first uplink time ratio information, first uplink percentage (or uplink duty cycle or uplink duty ratio or uplink ratio), or other similar names; this disclosure makes no limitation on this and they can be used interchangeably). The specific value of the time ratio information included in the first information, taking into account the specific design and manufacturing implementation of the UE at the corresponding power level, should ensure that when the HPUE transmits at the reported highest power level according to the reported uplink percentage, it meets the corresponding electromagnetic radiation regulatory requirements. The specific method of generating this value is not limited here.

[0108] The highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to that highest power level, included in the first information, can be obtained through...

[0109] Add a new IE to an existing Information Element (IE) in the UECapabilityInformation message (which is a response to the UECapabilityEnquiry message) or

[0110] A new method for reporting to the network has been added to the UECapabilityInformation message.

[0111] Similarly, the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to that highest power level, contained in the first information, can also be reported to the network in other messages by adding an IE or modifying an existing IE.

[0112] The highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power level contained in the first information can be indicated by two elements within an IE, or by the name of the IE and one of its contained elements.

[0113] When the first information includes the first time, similarly, the first time can be indicated by three elements within an IE, along with the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power level, or by the name of the IE and the multiple elements it contains.

[0114] For example, when the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to that highest power level are included in the first information,

[0115] When adding a new IE to the existing RF-Parameters IE in the UECapabilityInformation message, assuming the new IE is named ntn-HPUEConfig, the highest power level supported by the UE and the corresponding maximum uplink transmission time ratio information contained in the first information can be indicated by multiple elements within the new IE. For example, the highest power level supported by the UE can be indicated by the element ntn-powerClass contained in ntn-HPUEConfig; the maximum uplink transmission time ratio information corresponding to this highest power level can be indicated by the element ntn-maxUplinkRatio contained in ntn-HPUEConfig. When the first information includes a first time, the first time can be indicated by the element ntn-uplinkConfigTime contained in ntnHPUEConfig.

[0116] For example, if the information in the first information regarding the highest power class supported by the UE and the corresponding maximum uplink transmission time ratio is indicated by the name of a newly added IE and its constituent elements, then when the name of the newly added IE is ntn-maxUplinkRatio-PC2, this name indicates the highest power class supported by the UE (e.g., Power Class 2, or PC2 for short), and the elements contained in this IE can indicate the corresponding maximum uplink transmission time ratio. Similar IEs, such as ntn-maxUplinkRatio-PC1dot5 and ntn-maxUplinkRatio-PC1, can also be applied to other high power classes, such as Power Class 1.5 (PC1.5 for short) and Power Class 1 (PC1 for short). When the first information includes the first time, the name of the newly added IE can be ntn-HPUEConfig-PC2. The newly added IE name ntn-HPUEConfig-PC2 is used to indicate the highest power class supported by the UE (e.g., Power Class 2, or PC2 for short). The two elements contained in this IE can respectively indicate the maximum uplink transmission time ratio information corresponding to this highest power class (e.g., ntn-maxUplinkRatio) and the first time (e.g., ntn-uplinkConfigTime). Similarly, for other high power classes, such as Power Class 1.5 (PC1.5 for short) and Power Class 1 (PC1 for short), similar IEs as described above can also be applied, such as ntn-HPUEConfig-PC1dot5 and ntn-HPUEConfig-PC1, etc.

[0117] Optionally, in addition to including the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power level, the first information may also include a first time. The first time is the effective time or duration of the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power level. That is, the first time can be used to report to the network that the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power level are effective within the first time period.

[0118] The first time contained in the first information can be reported to the network by reporting the specific time length (such as the value X) and combining it with the corresponding time unit (such as millisecond (ms), second (s), microsecond (us), slot, symbol, subframe (SF), frame, etc.).

[0119] As one implementation, determining the validity period of the highest power level supported by the UE and the first uplink time ratio information can also be achieved by including first capability information in the first information. This first capability information is used to report to the network that the UE has the ability to dynamically configure the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to that highest power level. For example, the UE sends first information for the first time, and the first information includes first capability information, the highest supported power level, and the first uplink time ratio information (which can be understood as excluding the first time); after at least one of the highest supported power level and the first uplink time ratio information is updated, the UE sends first information a second time, and the first information includes first capability information, the highest supported power level, and the first uplink time ratio information. In this implementation, the validity period of the highest supported power level and the first uplink time ratio information included in the first information sent in the first transmission is determined as the difference between the time the network receives the first information for the second time and the time the network receives the first information for the first time.

[0120] If the first time included in the first information is implemented through a specific time length, and the network does not receive new first information when the specific time length of the first time ends, then the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to that highest power level, as indicated in the first information previously sent by the UE to the network, are considered still applicable. Similarly, if the first time is implemented by reporting first capability information, and the network does not receive updated information on the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to that highest power level, the previously reported information on the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to that highest power level is still applicable.

[0121] The UE can update two items in the previously sent first information, namely the highest power level supported by the UE and the maximum uplink transmission time ratio corresponding to the highest power level, or update only one of them, by sending a new first information.

[0122] If the first capability information is reported immediately, this first capability information can be implemented by adding elements to the newly added IE (such as ntn-HPUEConfig or ntn-HPUEConfig-PC2, etc.) in the above example. For example, when the element corresponding to the first capability information is named ntn-HPUE-dynamicConfig, if the first information reported by the UE carries this element, it should be understood that the UE indicates to the network that it has the ability to dynamically configure the highest power level supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power level.

[0123] Step S402: The network sends the second information to the UE.

[0124] The second information may include information associated with the second uplink time ratio information of the UE, wherein the second uplink time ratio information (also referred to as the second uplink time ratio information, the second uplink percentage, or other similar names, which are not limited in this disclosure and can be used interchangeably) can be determined based on the information associated with the second uplink time ratio information of the UE.

[0125] As one of the above methods, the second information may include, but is not limited to, one or more of the following:

[0126] - The proportion of uplink resources in the overall network configuration over time (e.g., this proportion could be a second proportion);

[0127] -Activation time ratio information configured by the network for the serving cell of the UE (e.g., the ratio information could be a third ratio);

[0128] - The activation time ratio information configured by the network for the beam in which the UE is located (for example, the ratio information may be a third ratio);

[0129] - The proportion of uplink resources configured by the network for the serving cell of the UE over time (e.g., this proportion is related to the values ​​of the second and third proportions);

[0130] - The proportion of uplink resources configured by the network for the beam in which the UE is located in time (e.g., the proportion information is related to the values ​​of the second proportion and the third proportion);

[0131] - The network allocates uplink resources specifically for this UE over time. (For example, this proportion information is related to the values ​​of the second and third proportions).

[0132] The second piece of information mentioned above can be broadcast by the network to all UEs within the cell via System Information Broadcast (SIB) messages, rather than being sent to a single UE. Alternatively, it can be configured for each UE via Medium Access Control (MAC) or Radio Resource Control (RRC) messages. When configuring each UE, different UEs can be configured with the same uplink percentage information, or different UEs can be configured with different uplink percentage information.

[0133] The proportional information included in the second piece of information mentioned above can be indicated by numerical values. For example, the network can agree to issue proportional values ​​such as 10%, 0.1, and 10 to indicate a proportion of 10%. Alternatively, certain proportional values ​​can be numbered, and the network can issue these numbers to indicate the proportional information. For instance, 5%, 10%, and 15% can be numbered 1, 2, and 3 respectively, in which case the network issues number 1 to indicate a proportion of 5%.

[0134] In the second piece of information mentioned above, the proportion of uplink resources configured by the network in terms of time can be the proportion of available time resources used for uplink communication that the network has configured for all cells and / or beams it serves in the current operating frequency band.

[0135] For an NTN network, the proportion of uplink resources configured in the network over time can be represented by the location (number) or number of uplink time resources configured within the agreed uplink resources, as well as the period information.

[0136] For example, the uplink time ratio information configured in the current network can be indicated to the UE by sending N time units (such as time slots, symbols, subframes, frames, etc.) indicating the configuration cycle period and M time units configured for uplink communication in that cycle. As an example, N and M can be sent separately using elements in the message.

[0137] Furthermore, the time resources indicating the configuration cycle period (N time units in the example above) or the time resources configured for uplink communication within that cycle (M time units in the example above) can be determined by convention. For example, when the protocol stipulates that the cycle period corresponding to the uplink configuration issued by the network defaults to 10 subframes, as an example, the element name issued by the network might be uplinkSFNin10SFN (N=10 and the time unit is subframe (SF)). That is, the cycle period corresponding to the agreed uplink configuration is reflected through the element name, and the content carried by this element is used to indicate the time resources configured for uplink communication (M in the example above). As another example, the cycle period corresponding to the agreed uplink configuration can also be implicitly reflected. That is, after the protocol is agreed upon, the time resources for configuring the cycle period (N time units in the example above) are no longer indicated or issued through element names or individual elements. In this case, the network only needs to issue the time resources configured for uplink communication (M in the example above).

[0138] Similarly, the time resources allocated for configuring the cycle (N time units in the example above) or the time resources allocated for uplink communication within that cycle (M time units in the example above) can also be specified in terms of the time resources allocated for uplink communication within the agreed cycle. For example, when the protocol specifies that the time resources allocated for uplink communication in each cycle are two consecutive subframes (i.e., M is 2 and the time unit is a subframe in the example above), the network only needs to send the cycle time information (N time units in the example above). The agreed-upon time resources allocated for uplink communication in each cycle can be explicitly stated in the message or implicitly stated through the protocol.

[0139] For example, when time units (such as time slots, symbols, subframes, frames, etc.) in the time resources of a configuration cycle are numbered by agreement, such as when the network specifies a cycle of 10 subframes by issuing or agreeing on a protocol, these 10 subframes in each cycle can be numbered from subframe 0 (SFN0) to subframe 9 (SFN9). In this case, the uplink time ratio information configured by the current network can be determined by the network sending the time resources (here, subframe numbers) configured for uplink transmission in the agreed cycle. As an example of this method, when the network issues subframe numbers SFN0 and SFN5 configured for uplink transmission, it indicates that subframe numbers 0 and 5 are configured for uplink transmission in the ten predetermined subframes from SFN0 to SFN9. This should be understood as indicating the uplink time ratio configured by the current network, i.e., 2 / 10 or 20% in this example. As another example of this approach, the uplink configuration of subframes 0 and 5, which are configured for uplink transmission within the period of subframe numbers 0 to 9 in the previous example, can be agreed upon in advance as a template (pattern). By agreeing on the number of this template (such as uplink configuration template 1), the network can then send out the template number, such as sending uplink configuration template 1, to indicate the uplink time ratio currently configured by the network.

[0140] For example, the agreed-upon uplink scheduling template number two might be: the first subframe (when the time unit is defined as a subframe) is an uplink subframe, the second, third, and fourth subframes are non-uplink subframes, the fifth subframe is an uplink subframe, and the sixth, seventh, and eighth subframes are non-uplink subframes, and so on. In this example, the uplink proportion of uplink scheduling template number one is 25% or 1 / 4. In this case, the network can instruct the UE to use this uplink scheduling template by issuing a number in the second information. For example, when the second information indicates the use of uplink scheduling template number two, it means instructing the UE that the current network-configured uplink proportion is 25%.

[0141] As mentioned earlier, the second information may also include the activation time ratio information configured by the network for the serving cell of the UE and / or the activation time ratio information configured by the network for the beam in which the UE is located. Depending on the network deployment, for example, when a satellite serves multiple cells or multiple beams, it can take turns serving different cells or beams at different times within the satellite's service range. This taking turns can be done uniformly, i.e., the uplink ratio of all cells or beams served by the satellite is the same, or it can be done unevenly, i.e., the uplink ratio of all cells or beams served by the satellite is different. In this case, the serving cell of the UE or the beam in which the UE is located can be in different activation ratios. The UE can only perform uplink and / or downlink services when the currently serving cell or the beam in which the UE is located is activated by the network. Similarly, this ratio information can be issued in various ways (e.g., through numerical forms, template numbers, etc.). The difference is that when instructing the network to configure the activated time ratio information for the serving cell of the UE and / or the activated time ratio information for the beam in which the UE is located, the network should issue the activated time ratio of the current serving cell or beam, the number of time units, the template or its number, or other expressions listed above.

[0142] For example, when using the aforementioned numerical expression, similarly, when the network-configured ratio of the cell or beam where the UE is located is activated can be a numerical value or a percentage, such as beamActivateRatio, then the value of this information can be a value less than or equal to 1. For example, a value of 0.25 represents that the network-configured ratio of the cell or beam where the UE is located is 25%; the value of this information can also be a value less than or equal to 100. For example, a value of 35 represents that the network-configured uplink time ratio of the cell or beam where the UE is located is 35%.

[0143] Furthermore, the activation time ratio information configured for the UE's serving cell and / or the activation time ratio information configured by the network for the UE's beam can also be indicated by priority (e.g., high, medium, low) or priority number (e.g., 1, 2, 3, 4). When using this method, the mapping relationship between priority and the aforementioned various expressions needs to be agreed upon. For example, when it is agreed that a high priority corresponds to an activation ratio of 20%, when the network issues a high priority for the current cell or beam activation, it means that the activation time ratio is 20%. The activation ratio of 20% in this example can also be indicated by the aforementioned other expressions. When using other expressions, similarly, it is necessary to agree upon the mapping relationship between priority and a set of periods and the number of times they are activated, or with an agreed activation template, or with a template number, etc.

[0144] As mentioned earlier, the second information may also include the temporal proportion of uplink resources configured by the network for the serving cell of the UE and / or the temporal proportion of uplink resources configured by the network for the beam in which the UE is located and / or the temporal proportion of uplink resources configured by the network individually for the UE. In this case, this information differs from the aforementioned temporal proportion of uplink resources configured by the network as a whole. It represents the uplink proportion configured by the network for the serving cell or beam in which the UE is located. This proportion can be determined by the network itself, combining its activation ratio for the current UE's serving cell or beam with the overall uplink resource proportion configured by the network, and then sent to the UE. In this case, the network determines this proportion information independently. Similarly, this ratio information can be issued in the aforementioned various ways. The difference lies in the fact that when the network is instructing the network to allocate the uplink resources of the serving cell of the UE in terms of time ratio and / or the network to allocate the uplink resources of the beam in which the UE is located in terms of time ratio and / or the network to allocate the uplink resources of the UE individually in terms of time ratio, the network should issue the uplink time ratio, the number of time units, the pattern or its number, or other expressions listed above that are configured for the current serving cell or beam or the current UE.

[0145] The time-based proportion of uplink resources configured by the network for the serving cell of the UE, the time-based proportion of uplink resources configured by the network for the beam in which the UE is located, or the time-based proportion of uplink resources configured by the network for the UE individually can also be determined by combining other information included in the second information. For example, when the second information simultaneously includes the time-based proportion of uplink resources configured by the network as a whole (e.g., X or the Xth proportion, etc.) and the activation time proportion information configured by the network for the beam in which the UE is located (or its serving cell) (e.g., Y or the Yth proportion, etc.), the time-based proportion of uplink resources configured by the network for the beam in which the UE is located (or its serving cell) can be jointly determined by X and Y.

[0146] One method of determination is that when the ratio information X and Y are converted into the percentage values ​​indicated by the aforementioned various expressions, the ratio information of the uplink resources configured by the network for the UE's beam (or its serving cell) in time is the product of the percentage values ​​indicated by X and Y.

[0147] Furthermore, considering the following situations that may occur in actual network deployments: although an activation ratio (Y) is set and issued for the current serving cell or its serving beam, the duration of a single activation may be close to or exceed the duration for which electromagnetic radiation regulations assess the UE's electromagnetic radiation. In this case, from the perspective of electromagnetic radiation regulations, the UE's transmission (or uplink transmission) duration may be considered sufficiently long during a single activation, meaning that its uplink transmission or electromagnetic radiation regulatory requirements are not affected by the activation ratio (Y) of the current serving cell or its serving beam. When considering this situation, another approach is to treat the uplink resource allocation for the UE's beam (or its serving cell) as the same as the overall uplink resource allocation (X) for the network, i.e., the activation time ratio (Y) allocated by the network for the UE's beam (or its serving cell) is not considered.

[0148] The second information is intended to indicate to the UE the proportion of resources configured in the current network that can schedule the UE to perform uplink transmission over time. The second information is expressed in different ways in this disclosure, and its expression is not limited to a numerical proportion. It can also be one of the aforementioned expressions or other forms.

[0149] Optionally, the second information may include, in addition to indicating to the UE the proportion of resources configured in the current network that can schedule the UE to perform uplink transmission over time (i.e., the uplink time proportion information configured in the current network), the effective time (second time) corresponding to the uplink time proportion information. As one implementation, if the first information includes a first time, the second time included in the second information may be the same as the first time.

[0150] Step S403: Determine the UE's transmit power based on the first information and the second information.

[0151] When the first time ratio information is greater than or equal to the second time ratio information, the UE should maintain its transmission at the transmission power corresponding to the current power level, that is, it does not need to reduce or back off the transmission power for electromagnetic radiation regulations.

[0152] When the first time ratio information is less than the second time ratio information, the UE can determine its transmit power through one or a combination of the following methods.

[0153] Method 1: The UE's transmit power is reduced or rolled back according to a first time ratio (e.g., X%) and a second time ratio (e.g., Y%), wherein the reduced or rolled-back power value is calculated based on the first time ratio (e.g., X%) and the second time ratio (e.g., Y%). As one implementation, the UE's transmit power is obtained by reducing the transmit power P_powerclass corresponding to its supported power level by 10*log10(Y / X) dB, or by reducing the transmit power to P_powerclass – 10*log10(Y / X) dBm. It is understood that 10*log10(Y / X) dB is merely an example of a reduced or rolled-back power value and is not intended to limit this disclosure.

[0154] Considering that in practical applications, the power value of the reduction or rollback may be a decimal after mathematical calculation, it can be agreed that the significant number of decimal places is 1, or rounded up, or rounded up to an integer multiple of a predetermined step size. For example, when the second ratio information is 25% and the first ratio information is 15%, the power value of the reduction or rollback 10*log10(25 / 15) can be 2.2 (1 significant number of decimal places), 3 (rounded up), or 2.5 (rounded up to an integer multiple of 0.5 (step size)).

[0155] Considering the various ways in which the aforementioned first and second proportional information can be expressed, when this proportional information is reported or distributed from certain agreed-upon proportional values ​​through numbering or other means, the aforementioned calculation or value-taking method can be implicitly reflected. In this case, the reduced or reverted power value can be expressed as being determined by the combination of the numbers of the first and second proportional information.

[0156] For example, when the first proportion information is reported by selecting from 10% and 15% through numbering, and its corresponding number is 0 and 1 (as shown in Table 1 below), and the second proportion information is reported by selecting from 10% and 20% through numbering, and its corresponding number is 0 and 1 (as shown in Table 2 below), the rollback value can be determined by the reporting number of the first proportion information and the distribution number of the second proportion information, as shown in Table 3 below. The power value of the reduced or rolledback transmission power in Table 3 is determined by the aforementioned method (10*log10(Y / X)), but is not visible in this representation. The table is only intended to show one way of representing the values ​​with the reporting numbers of the first and second proportion information, and is not limited to being expressed through text or other means.

[0160] Second proportion information number Uplink proportion information indicated by the second proportion information 0 10％ 1 20％

[0161] Table 3 Power values ​​of reduction or regression

[0162]

[0163] Method 2: The UE's transmit power is not reduced or downgraded; that is, the UE transmits at the transmit power corresponding to its power level. In this case, the UE can use one or more of the following methods in combination to maintain its high power level transmit power.

[0164] Method 2-1: The UE reduces its uplink transmission ratio for a certain period of time by entering an uplink transmission pause state (also known as the first state, or other similar names, which are not limited in this disclosure and can be used interchangeably).

[0165] When applied, the first information may include a fourth information, which is intended to inform the network that the UE supports the uplink transmit pause capability (also referred to as a second capability; this disclosure does not impose any limitations on this, and they can be used interchangeably). The UE reporting this fourth information can maintain its high-power transmission level and address electromagnetic radiation regulations by pausing uplink transmit.

[0166] The fourth piece of information can be reported in a manner similar to the first piece of information, or it can be included in the first piece of information. For example, when the fourth piece of information is included in the first piece of information, as one of the above methods, the element name indicating the fourth piece of information can be ntn-hpue-tx-gap, and the element indicating the fourth piece of information can be included in IE such as ntn-HPUEConfig or ntn-HPUEConfig-PC2 as mentioned in the previous example.

[0167] For UEs supporting the second capability, they can monitor their transmission power and transmission time under electromagnetic radiation requirements within a certain time period (e.g., a third time period, also known as a second preset time period) based on their own design and implementation. When the uplink transmission duration scheduled for the UE within the third time period is greater than or equal to the transmission duration it considers safe (also known as a first preset transmission duration), or when the uplink transmission duration scheduled for the UE within the third time period is greater than or equal to the uplink transmission duration corresponding to the first time ratio information, the UE sends a third message to the network and suspends its uplink transmission starting from the fifth time period after sending the third message. The purpose of this third message is to report to the network that it has suspended its uplink transmission starting from the fifth time period after sending the third message.

[0168] The fifth time is the start time after the UE reports the third information to the network and then suspends its uplink transmission. The fifth time is determined by a preset method. For example, one preset method for the fifth time is to stipulate that the fifth time is the next time unit after the time unit (time slot, symbol, subframe, frame, etc.) in which the UE sends the third information.

[0169] For example, when the fifth time is agreed to be the next time slot after the time slot in which the UE sends the third information (in this example, the time unit is a time slot), after the UE sends the third information to the network, the UE should start from the next time slot after the time slot in which the third information is located, or the UE should start from the first symbol of the next time slot after the time slot in which the third information is located, without uplink transmission.

[0170] When a UE enters an uplink transmit pause state, or pauses uplink transmit, the UE should cease transmitting on uplink transmit channels including but not limited to PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel), and SRS (Sounding Reference Signal). However, during the UE's uplink transmit pause, or while the UE is in an uplink transmit pause state, the UE's downlink reception and downlink channel measurements are unaffected.

[0171] The third information may include the aforementioned fourth time (also referred to as the first time period). The fourth time is the duration during which the UE will suspend its uplink transmission starting from the fifth time after transmitting the third information to the network, or the duration during which the UE will be in the first state (e.g., entering a state of stopped uplink transmission) after transmitting the third information to the network. This fourth time can be expressed numerically, with units such as millimeters, seconds, time slots, symbols, subframes, and frames. Alternatively, the fourth time can be implicitly expressed through convention. Specifically, when the UE transmits the third information to the network, the corresponding fourth time is defined by the specification as W milliseconds, seconds, time slots, symbols, subframes, and frames. When implicitly expressed, the third information does not need to include a specific numerical value for the fourth time.

[0172] For example, when a UE reports support for ntn-hpue-tx-gap (the capability indicated by the fourth information, e.g., the second capability), after the UE reports the third information (i.e., information indicating its entry into an uplink transmit pause state, e.g., ntn-hpue-tx-gap-on) and this third information includes a fourth time (e.g., ntn-hpue-tx-gap-time), the UE should cease its uplink transmission within the first symbol of the next time slot following the time slot in which it reported the third information (the fifth time), and its transmit power should meet the requirements of the transmit OFF power during this fourth time. Furthermore, the UE should be ready for uplink transmission before the end of the fourth time. This statement aims to ensure that during the fourth time as described in Scheme 2-1, the UE enters the uplink transmit pause state and disables uplink transmission. Furthermore, this statement ensures that the UE can resume uplink transmission at any time after the end of the fourth time period, meaning that the UE should be ready to resume uplink transmission before the end of the fourth time period.

[0173] For example, when a UE reports support for ntn-hpue-tx-gap (the capability indicated by the fourth information, e.g., the second capability), after reporting the third information (i.e., information indicating its entry into an uplink transmit pause state, e.g., ntn-hpue-tx-gap-on) and assuming the fourth time is agreed to be 10 subframes, the UE will cease its uplink transmission for 10 subframes starting from the next subframe after the subframe containing the time slot where it reported ntn-hpue-tx-gap-on (the fifth time). During this fourth time, its transmit power should meet the requirements of the transmit-off power. Furthermore, the UE should be ready for uplink transmission before the end of the fourth time.

[0174] Optionally, when the third information (e.g., ntn-hpue-tx-gap-on) does not include the aforementioned fourth time (or first time period), and the fourth time is not implicitly agreed upon as described above, the UE suspends its uplink transmission until it sends the seventh information (ntn-hpue-tx-gap-off) to the network to indicate the end of its uplink transmission suspension and resumes its uplink transmission. The seventh information is sent by the UE to the network to indicate the end of its uplink transmission suspension or to exit the uplink transmission suspension state, allowing the network to resume its uplink scheduling of the UE.

[0175] For example, when a UE reports support for ntn-hpue-tx-gap (the capability indicated by the fourth information, e.g., the second capability), after reporting the third information (i.e., information indicating its entry into an uplink transmit pause state, e.g., ntn-hpue-tx-gap-on), the UE stops its uplink transmission from the next subframe (the fifth time frame) following the subframe containing the time slot where it reported ntn-hpue-tx-gap-on, until the UE sends the seventh information (ntn-hpue-tx-gap-off). For a UE reporting support for ntn-hpue-tx-gap (the capability indicated by the fourth information, e.g., the second capability), its transmit power should meet the transmit OFF power requirements after reporting the third information (e.g., ntn-hpue-tx-gap-on) and before reporting the seventh information (ntn-hpue-tx-gap-off). During this period, the UE should stop its uplink transmission in areas including, but not limited to, PUSCH (Uplink Physical Shared Channel).

[0176] (Physical Uplink Shared Channel) and PUCCH (Uplink Physical Control Channel)

[0177] Transmissions on uplink transmission channels such as the Physical Uplink Control Channel (Phase I) and the Sounding Reference Signal (SRS) are allowed. However, downlink reception and measurements of the downlink channel are unaffected when the UE suspends uplink transmission or is in an uplink transmission paused state.

[0178] Method 2-1 can also be started by a third message (e.g., ntn-hpue-tx-gap-on) and additionally include a periodic configuration for a transmission interruption via an eighth message.

[0179] For example, the eighth information could include the UE's uplink transmission for the first y time units (e.g., milliseconds, seconds, time slots, symbols, subframes, frames, etc.) within every x time units (e.g., milliseconds, seconds, time slots, symbols, subframes, frames, etc.) after the start of the third information indication. Conversely, the eighth information could also include the UE's non-uplink transmission for the first y time units (e.g., milliseconds, seconds, time slots, symbols, subframes, frames, etc.) within every x time units (e.g., milliseconds, seconds, time slots, symbols, subframes, frames, etc.) after the start of the third information indication. During the time units configured in the eighth information where uplink transmission is not performed, the UE should cease transmitting on uplink transmission channels including but not limited to PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel), and SRS (Sounding Reference Signal). However, the UE's downlink reception and measurements of the downlink channels are unaffected.

[0180] The eighth piece of information can be included in the fourth piece of information and reported to the network by the UE at the same time as reporting its second capability. In this case, after the UE reports the third piece of information, the UE should start from the fifth time point to execute the periodic configuration of the transmission interruption reported in the eighth piece of information.

[0181] The eighth information can also be included in the third information. In this case, after the UE reports the third information (which includes the eighth information), the UE should start from the fifth time period and execute the periodic configuration of the transmission interruption reported in the eighth information.

[0182] Similarly, for this periodic interruption configuration (indicated by the eighth message), the UE needs to begin executing this transmission interruption configuration at the fifth time after transmitting the third message, and continue until the fourth time (when the UE reports the fourth time) or until the UE transmits the seventh message (when the UE does not report the fourth time and uses the aforementioned seventh message to indicate the interruption status has stopped / exited). The UE needs to be ready to resume its normal uplink transmission before this interruption configuration ends, that is, to return to a state where uplink transmission can be continuous and uninterrupted.

[0183] For example, when a UE reports support for ntn-hpue-tx-gap (the capability indicated by the fourth information), it includes the eighth information. Assuming the interruption period configured by the eighth information is uplink transmission for the first four subframes out of every ten subframes, after the UE reports the third information (i.e., information indicating its entry into an uplink transmission pause state, such as ntn-hpue-tx-gap-on), the UE should meet the transmit OFF power requirements for the last six subframes out of every ten subframes starting from the subframe following the subframe in which it reported the third information (within time units without uplink transmission). This statement aims to ensure that during the interruption time indicated by the eighth information in this configuration, the UE enters the uplink transmission pause state and disables uplink transmission.

[0184] The uplink transmission pause in method 2-1 can also be combined with the aforementioned power level backoff method. That is, when the UE reports the third information, its transmission power should be backoffed from the high power level it supports to an agreed power level, such as backoff to the transmission power of power level 3 (PC3) within the fourth time period.

[0185] Method 2-2: The UE reduces the proportion of its actual uplink transmission time by discarding (or dropping, skipping, etc.) uplink transmission opportunities according to a certain proportion (also known as the first proportion).

[0186] The UE decides which uplink transmission opportunities to discard based on the first time ratio information (e.g., X%) and the second time ratio information (e.g., Y%), combined with its actual uplink scheduling status. In this mode 2-2, the UE and the network agree through a protocol that the UE is allowed to discard a maximum of (1-X / Y)% of uplink transmissions or uplink transmission opportunities.

[0187] When the first information contains a first time and the second information contains a second time, i.e., when both the first and second times are applied simultaneously, the uplink transmission discarding behavior and its permitted proportion in this scheme should be limited to the effective time of the first or second time; that is, the uplink transmission discarding behavior and its permitted proportion are effective within the first or second time. As one possible approach, the first time under this condition can be equal to the second time.

[0188] When the first information contains a first time or the second information contains a second time, that is, when the first time and the second time are applied separately, the uplink transmission discarding behavior and its permitted proportion in this scheme should be limited to the first time or the second time in which it is applied. That is, the uplink transmission discarding behavior and its permitted proportion are valid in the first time or the second time.

[0189] When applying method 2-2, the first information may include fifth information, which is intended to inform the network that the UE supports the capability to discard uplink transmission opportunities at a certain ratio (also referred to as the third capability; this disclosure does not impose any limitations on this, and they can be used interchangeably). The UE that reports this fifth information can maintain its high-power transmission level and address electromagnetic radiation regulations through method 2-2.

[0190] For example, when the fifth information is included in the first information, as described above, the element name indicating the fifth information can be ntn-hpue-tx-drop, and the element indicating the fifth information can be included in IE such as ntn-HPUEConfig or ntn-HPUEConfig-PC2 as mentioned in the previous example.

[0191] As another implementation, the second time ratio information may not be indicated to the UE through the SIB, MAC, RRC, or other messages mentioned in the second step. For example, after the UE sends the first information to the network, the network may send the sixth information to the UE based on the first information to indicate the UE's transmit power configuration.

[0192] The sixth piece of information here may include one or more of the following to instruct the UE to configure its transmit power:

[0193] (1) Information related to the power that the UE needs to back up, such as the power value (dB) that the UE needs to back up;

[0194] (2) Information related to whether the UE needs to fall back to the next power level, such as whether the UE needs to fall back to a lower power level. For example, falling back from power level 2 to power level 3, or falling back from power level 1.5 to power level 2, etc.

[0195] (3) Information related to the target power level to which the UE needs to fall back, such as the target power level to which the UE needs to fall back.

[0196] When the UE power configuration method indicated by the sixth message is agreed upon through the protocol, whether or not the sixth message is received can also serve as an indication for the UE to configure its transmit power. For example, if the protocol stipulates that when the UE receives the sixth message, assuming the sixth message is ntn-hpue-tx-fallback, its transmit power needs to fall back to the next lower power level, then when the UE receives ntn-hpue-tx-fallback, it will perform the power fallback according to the agreed method; when the UE does not receive ntn-hpue-tx-fallback, it will maintain the transmit power corresponding to its power level and continue transmitting.

[0197] Similarly, when the UE power configuration method indicated by the sixth information is agreed upon through the protocol, the sixth information can also indicate whether the UE performs power configuration according to the agreed method using 0 or 1. For example, assuming the sixth information is ntn-hpue-tx-fallback, when the protocol stipulates that the UE receives ntn-hpue-tx-fallback as 1, its transmit power needs to fall back to the next lower power level; when the UE receives ntn-hpue-tx-fallback as 0, it maintains the transmit power corresponding to its power level. When this method is applied, the numbers contained in the sixth information, such as 0, 1, 2..., can also be mapped to the different UE power configuration methods indicated by the sixth information. In this method, the UE performs the corresponding transmit power configuration according to the number contained in the sixth information it receives.

[0198] The power configuration can be described in the following way in the above scheme.

[0199] The formula for configuring the transmission power is as follows:

[0200] The UE is allowed to set its configured maximum output power P for carrier f and serving cell c in each time slot. CMAX,f,c The configured maximum output power P CMAX,f,c It is set within the following range:

[0201] P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c

[0202] P CMAX_L,f,c It is the lower limit of the interval, P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –

[0203] ΔP PowerClass +ΔP PowerBoost )–MAX(MAX(MPR c +ΔMPR c A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS P-MPR c )}

[0204] P CMAX_H,f,c It is the upper limit of the interval, P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass +ΔPPowerBoost}

[0205] in,

[0206] P EMAX,c It is the maximum transmit power of cell c configured by the network.

[0207] P PowerClass It is the maximum UE power under the corresponding power level specified in the protocol;

[0208] ΔP PowerClass It is the dB value of power reduction allowed when power level rollback is performed as specified in the agreement, which may be 0dB, 3dB or 6dB depending on the conditions;

[0209] ΔP PowerBoost It is the allowable power increase in dB as specified in the protocol, which depends on the conditions.

[0210] ΔT C,c It refers to the tolerance specified in the agreement for a specific frequency band;

[0211] MPR c It is the value of the maximum output power reduction (MPR) specified in the protocol;

[0212] ΔMPR c It is the MPR correction value specified in the agreement.

[0213] A-MPR c It is the value of the Additional maximum output power reduction (A-MPR) specified in the protocol.

[0214] ΔT RxSRS It is the power correction value specified in the protocol for the transmission of the Sounding Reference Signal (SRS) under specific conditions.

[0215] P-MPR c It is the maximum power reduction value for power management, used to meet regulatory requirements such as electromagnetic radiation.

[0216] In the above formula for configuring transmission power, ΔP PowerClass It is a power backoff value corresponding to the power level. In other words, the UE can only backoff a fixed power backoff value of 3dB, 6dB, or 0dB (i.e., no backoff) corresponding to the power level, and cannot dynamically calculate the UE's transmit power backoff value.

[0217] The transmit power backoff value of the UE determined in the various embodiments of this disclosure is not a fixed power backoff value corresponding to the power level, but is determined based on the first information, or based on the first and second information, or based on the first and sixth information, making it more flexible. The specific ΔP provided in this disclosure... PowerClass Please refer to the following description for the implementation method.

[0218] (1) For method 1: Determine the UE’s transmit power back-off value based on the first information and the second information.

[0219] Method 1 in step 3 above can be achieved by using the variable ΔP in the above formula. PowerClass This is done by adding corresponding power settings and rollback values. The following is one example of how this method is applied:

[0220] ΔP PowerClass =

[0221] -A dB, representing the percentage of the maximum uplink time supported by the UE as reported in the first information, for example, X%.

[0222] When it is less than the percentage of uplink time configured in the network as sent by the network in the second information, for example, Y%.

[0223] At this point, A = 10 * log10(Y / X).

[0224] -0dB, when in other situations.

[0225] In the above statement, ΔP PowerClass =AdB's condition, namely "when the percentage of the maximum uplink time that the UE supports, reported in the first information, for example, X%, is less than the percentage of uplink time configured in the network, as reported by the network in the second information, for example, Y%,", can also include various implementation examples and expressions of the aforementioned first and second information. In some of these expressions, X and Y are indicated directly or indirectly through elements or other means. In such cases, X and Y may not be explicitly reflected in the description.

[0226] For example, when the maximum uplink time ratio supported by the UE in the first information is indicated by the ntn-maxUplinkRatio element in the previous example in the form of a percentage or a decimal less than or equal to 1, and when the uplink time ratio configured by the network in the second information is indicated by uplinkSFNin10SFN in the previous example, this is equivalent to indicating that X = ntn-maxUplinkRatio in the current example.

[0227] Y = uplinkSFNin10SFN / 10. Then A = 10*log10(uplinkSFNin10SFN / (10*ntn-maxUplinkRatio)).

[0228] The expression at this point might be as follows:

[0229] ΔP PowerClass =

[0230] -AdB, when the ntn-maxUplinkRatio reported by the UE in the first message is less than the ratio corresponding to uplinkSFNin10SFN sent by the network in the second message. At this time,

[0231] 10*log10(uplinkSFNin10SFN / (10*ntn-maxUplinkRatio)).

[0232] -0dB, when in other situations.

[0233] The various implementation examples and expressions of the aforementioned first and second information will have a corresponding impact on the description here, but will not affect the specific value of the power backoff determined by the method described in Method 1. Not all possible expressions are listed here.

[0234] (2) For methods 2-1 and 2-2: Based on the first information, determine the UE’s transmit power backoff value.

[0235] When applying methods 2-1 and 2-2 in step 3 above, the transmit power configuration formula can be augmented with a condition: that is, when the UE reports the fourth information (e.g., ntn-hpue-tx-gap), or when the UE reports the fifth information (e.g., ntn-hpue-tx-drop), and when ΔP PowerClass and P-MPR c Setting it to 0 indicates that the UE should transmit at the power corresponding to its high power level (i.e., P in the example). PowerClass To emit without reducing or backing up power to address regulatory issues related to electromagnetic radiation.

[0236] At this point, one possible definition for these two variables is:

[0237] -ΔP PowerClass =

[0238] -0dB, when the UE reports ntn-hpue-tx-gap, or when the UE reports ntn-hpue-tx-drop, and in other cases.

[0239] The remaining values ​​of this variable follow other rules and are unrelated to how they are implemented here.

[0240] (3) For the sixth information, for example, when the sixth information is ntn-hpue-tx-fallback, the UE's transmit power fallback value is determined based on the first information and the sixth information.

[0241] When ntn-hpue-tx-fallback (sixth information) contains the power value (dB) required for the UE to fall back, then ΔP in the above transmit power configuration formula... PowerClass This can be expressed as:

[0242] -ΔP PowerClass =

[0243] -ntn-hpue-tx-fallback(dB) is sent by the network when the UE reports the first information (containing various possible expressions of the first information).

[0244] -0dB, when the UE reports the first information (including various possible representations of the first information) and the network does not send ntn-hpue-tx-fallback, or in other situations.

[0245] When ntn-hpue-tx-fallback (sixth information) contains the target power level the UE needs to fall back to, for example, when ntn-hpue-tx-fallback (sixth information) indicates the target fallback level as PC3, PC2, or PC1.5, ΔP in the above transmit power configuration formula... PowerClass This can be expressed as:

[0246] -ΔP PowerClass =

[0247] -2dB, when the UE reports the first information (containing various possible expressions of the first information) indicating that the UE supports the power level of PC1 and the network issues ntn-hpue-tx-fallback as PC1.5.

[0248] -3dB, when the UE reports the first information (including various possible expressions of the first information) indicating that the UE supports the power level PC2 and the network issues ntn-hpue-tx-fallback as PC3; or when the UE reports the first information (including various possible expressions of the first information) indicating that the UE supports the power level PC1.5 and the network issues ntn-hpue-tx-fallback as PC2.

[0249] -5dB, when the UE reports the first information (containing various possible expressions of the first information) indicating that the UE supports the power level PC1 and the network issues ntn-hpue-tx-fallback as PC2.

[0250] -6dB, when the UE reports the first information (containing various possible expressions of the first information) indicating that the UE supports the power level of PC1.5 and the network issues ntn-hpue-tx-fallback as PC3.

[0251] -8dB, when the UE reports the first information (containing various possible expressions of the first information) indicating that the UE supports the power level PC1 and the network issues ntn-hpue-tx-fallback as PC3.

[0252] -0dB, when the UE reports the first information (including various possible expressions of the first information) and the network issues the target power level indicated by ntn-hpue-tx-fallback, which is the same as the power level reported in the first information, or when the UE reports the first information (including various possible expressions of the first information) and the network does not issue ntn-hpue-tx-fallback, or in other cases.

[0253] Furthermore, as described in the scheme, when applying the above-mentioned multiple methods, the variable P-MPR in the transmit power configuration formula in this example... c It should be set to 0. That is, when applying this solution, no other power backoff should be applied to address electromagnetic radiation regulatory requirements.

[0254] Once the UE's transmit power configuration is determined using the method described in this scheme, the maximum output power PCMAX,f,c configured in the above formula will be reported to the network through other protocol-agreed methods. The subsequent process will not be described here.
