[0002] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in "Sub 6GHz" bands such as 3.5GHz, but also in "Above 6GHz" bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.
[0003] At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

Therefore, 5G or pre-5G communication systems are also called "Beyond 4G networks" or "Post-LTE systems".
[0008] In order to achieve a higher data rate, 5G communication systems are implemented in higher frequency (millimeter, mmWave) bands, e.g., 60 GHz bands. In order to reduce propagation loss of radio waves and increase a transmission distance, technologies such as beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antenna, analog beamforming and large-scale antenna are discussed in 5G communication systems.

[0071] Figure 1 illustrates an example wireless network 100 according to various embodiments of the present disclosure. The embodiment of the wireless network 100 shown in Figure 1 is for illustration only. Other embodiments of the wireless network 100 can be used without departing from the scope of the present disclosure.
[0072] The wireless network 100 includes a gNodeB (gNB) 101, a gNB 102, and a 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 private IP network, or other data networks.
[0073] Depending on a type of the network, other well-known terms such as "base station" or "access point" can be used instead of "gNodeB" or "gNB". For convenience, the terms "gNodeB" and "gNB" are used in this patent document to refer to network infrastructure components that provide wireless access for remote terminals. And, depending on the type of the network, other well-known terms such as "mobile station", "user station", "remote terminal", "wireless terminal" or "user apparatus" can be used instead of "user equipment" or "UE". For convenience, the terms "user equipment" and "UE" are used in this patent document to refer to remote wireless devices that wirelessly access the gNB, no matter whether the UE is a mobile device (such as a mobile phone or a smart phone) or a fixed device (such as a desktop computer or a vending machine).
[0074] gNB 102 provides wireless broadband access to the network 130 for a first plurality of User Equipments (UEs) within a coverage area 120 of gNB 102. The first plurality of UEs include a UE 111, which may be located in a Small Business (SB); a UE 112, which may be located in an enterprise (E); a UE 113, which may be located in a WiFi Hotspot (HS); a UE 114, which may be located in a first residence (R); a UE 115, which may be located in a second residence (R); a UE 116, which may be a mobile device (M), such as a cellular phone, a wireless laptop computer, a wireless PDA, etc. GNB 103 provides wireless broadband access to network 130 for a second plurality of UEs within a coverage area 125 of gNB 103. The second plurality of UEs include a UE 115 and a UE 116. In some embodiments, one or more of gNBs 101-103 can communicate with each other and with UEs 111-116 using 5G, Long Term Evolution (LTE), LTE-A, WiMAX or other advanced wireless communication technologies.
[0075] The dashed lines show approximate ranges of the coverage areas 120 and 125, and the ranges are shown as approximate circles merely for illustration and explanation purposes. It should be clearly understood that the coverage areas associated with the gNBs, such as the coverage areas 120 and 125, may have other shapes, including irregular shapes, depending on configurations of the gNBs and changes in the radio environment associated with natural obstacles and man-made obstacles.
[0076] As will be described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook designs and structures for systems with 2D antenna arrays.
[0077] Although Figure 1 illustrates an example of the wireless network 100, various changes can be made to Figure 1. The wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement, for example. Furthermore, gNB 101 can directly communicate with any number of UEs and provide wireless broadband access to the network 130 for those UEs. Similarly, each gNB 102-103 can directly communicate with the network 130 and provide direct wireless broadband access to the network 130 for the UEs. In addition, gNB 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.
[0078] FIGs. 2a and 2b illustrate example wireless transmission and reception paths according to the present disclosure. In the following description, the transmission path 200 can be described as being implemented in a gNB, such as gNB 102, and the reception path 250 can be described as being implemented in a UE, such as UE 116. However, it should be understood that the reception path 250 can be implemented in a gNB and the transmission path 200 can be implemented in a UE. In some embodiments, the reception path 250 is configured to support codebook designs and structures for systems with 2D antenna arrays as described in embodiments of the present disclosure.
[0079] The transmission path 200 includes a channel coding and modulation block 205, a Serial-to-Parallel (S-to-P) block 210, a size N 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 reception path 250 includes a down-converter (DC) 255, a cyclic prefix removal block 260, a Serial-to-Parallel (S-to-P) block 265, a size N Fast Fourier Transform (FFT) block 270, a Parallel-to-Serial (P-to-S) block 275, and a channel decoding and demodulation block 280.
[0080] In the transmission path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as Low Density Parity Check (LDPC) coding), and modulates the input bits (such as using Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM)) to generate a sequence of frequency-domain modulated symbols. The Serial-to-Parallel (S-to-P) block 210 converts (such as demultiplexes) serial modulated symbols into parallel data to generate N parallel symbol streams, where N is a size of the IFFT / FFT used in gNB 102 and UE 116. The size N IFFT block 215 performs IFFT operations on the N parallel symbol streams to generate a time-domain output signal. The Parallel-to-Serial block 220 converts (such as multiplexes) parallel time-domain output symbols from the Size N IFFT block 215 to generate a serial time-domain signal. The cyclic prefix addition block 225 inserts a cyclic prefix into the time-domain signal. The up-converter 230 modulates (such as up-converts) the output of the cyclic prefix addition block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at a baseband before switching to the RF frequency.
[0081] The RF signal transmitted from gNB 102 arrives at UE 116 after passing through the wireless channel, and operations in reverse to those at gNB 102 are performed at UE 116. The down-converter 255 down-converts the received signal to a baseband frequency, and the cyclic prefix removal block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. The Serial-to-Parallel block 265 converts the time-domain baseband signal into a parallel time-domain signal. The Size N FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. The Parallel-to-Serial block 275 converts the parallel frequency-domain signal into a sequence of modulated data symbols. The channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.
[0082] Each of gNBs 101-103 may implement a transmission path 200 similar to that for transmitting to UEs 111-116 in the downlink, and may implement a reception path 250 similar to that for receiving from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 may implement a transmission path 200 for transmitting to gNBs 101-103 in the uplink, and may implement a reception path 250 for receiving from gNBs 101-103 in the downlink.
[0083] Each of the components in FIGs. 2a and 2b can be implemented using only hardware, or using a combination of hardware and software / firmware. As a specific example, at least some of the components in FIGs. 2a and 2b may be implemented in software, while other components may be implemented in configurable hardware or a combination of software and configurable hardware. For example, the FFT block 270 and IFFT block 215 may be implemented as configurable software algorithms, in which the value of the size N may be modified according to the implementation.
[0084] Furthermore, although described as using FFT and IFFT, this is only illustrative and should not be interpreted as limiting the scope of the present disclosure. Other types of transforms can be used, such as Discrete Fourier transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions. It should be understood that for DFT and IDFT functions, the value of variable N may be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N may be any integer which is a power of 2 (such as 1, 2, 4, 8, 16, etc.).
[0085] Although FIGs. 2a and 2b illustrate examples of wireless transmission and reception paths, various changes may be made to FIGs. 2a and 2b. For example, various components in FIGs. 2a and 2b can be combined, further subdivided or omitted, and additional components can be added according to specific requirements. Furthermore, FIGs. 2a and 2b are intended to illustrate examples of types of transmission and reception paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.
[0086] Figure 3a illustrates an example UE 116 according to the present disclosure. The embodiment of UE 116 shown in Figure 3a is for illustration only, and UEs 111-115 of Figure 1 can have the same or similar configuration. However, a UE has various configurations, and Figure 3a does not limit the scope of the present disclosure to any specific implementation of the UE.
[0087] UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a transmission (TX) processing circuit 303, a microphone 304, and a reception (RX) processing circuit 305. UE 116 also includes a speaker 306, a controller / processor 307, an input / output (I / O) interface 308, an input device(s) 309, a display 310, and a memory 311. The memory 311 includes an operating system (OS) 312 and one or more applications 313.
[0088] The RF transceiver 302 receives an incoming RF signal transmitted by a gNB of the wireless network 100 from the antenna 301. The RF transceiver 302 down-converts the incoming RF signal to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is transmitted to the RX processing circuit 305, where the RX processing circuit 305 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuit 305 transmits the processed baseband signal to speaker 306 (such as for voice data) or to controller / processor 307 for further processing (such as for web browsing data).
[0089] The TX processing circuit 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. The TX processing circuit 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 302 receives the outgoing processed baseband or IF signal from the TX processing circuit 303 and up-converts the baseband or IF signal into an RF signal transmitted via the antenna 301.
[0090] The controller / processor 307 can include one or more processors or other processing devices and execute an OS 312 stored in the memory 311 in order to control the overall operation of UE 116. For example, the controller / processor 307 can control the reception of forward channel signals and the transmission of backward channel signals through the RF transceiver 302, the RX processing circuit 305 and the TX processing circuit 303 according to well-known principles. In some embodiments, the controller / processor 307 includes at least one microprocessor or microcontroller.
[0091] 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 systems with 2D antenna arrays as described in embodiments of the present disclosure. The controller / processor 307 can move data into or out of the memory 311 as required by an execution process. In some embodiments, the controller / processor 307 is configured to execute the application 313 based on the OS 312 or in response to signals received from the gNB or the operator. The controller / processor 307 is also coupled to an I / O interface 308, where the I / O interface 308 provides UE 116 with the ability to connect to other devices such as laptop computers and handheld computers. I / O interface 308 is a communication path between these accessories and the controller / processor 307.
[0092] The controller / processor 307 is also coupled to the input device(s) 309 and the display 310. An operator of UE 116 can input data into UE 116 using the input device(s) 309. The display 310 may be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). The memory 311 is coupled to the controller / processor 307. A part of the memory 311 can include a random access memory (RAM), while another part of the memory 311 can include a flash memory or other read-only memory (ROM).
[0093] Although Figure 3a illustrates an example of UE 116, various changes can be made to Figure 3a. For example, various components in Figure 3a can be combined, further subdivided or omitted, and additional components can be added according to specific requirements. As a specific example, the controller / processor 307 can be divided into a plurality of processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although Figure 3a illustrates that the UE 116 is configured as a mobile phone or a smart phone, UEs can be configured to operate as other types of mobile or fixed devices.
[0094] Figure 3b illustrates an example gNB 102 according to the present disclosure. The embodiment of gNB 102 shown in Figure 3b is for illustration only, and other gNBs of Figure 1 can have the same or similar configuration. However, a gNB has various configurations, and Figure 3b does not limit the scope of the present disclosure to any specific implementation of a gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structures as gNB 102.
[0095] As shown in Figure 3b, gNB 102 includes a plurality of antennas 370a-370n, a plurality of RF transceivers 372a-372n, a transmission (TX) processing circuit 374, and a reception (RX) processing circuit 376. In certain embodiments, one or more of the plurality of antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.
[0096] RF transceivers 372a-372n receive an incoming RF signal from antennas 370a-370n, such as a signal transmitted by UEs or other gNBs. RF transceivers 372a-372n down-convert the incoming RF signal to generate an IF or baseband signal. The IF or baseband signal is transmitted to the RX processing circuit 376, where the RX processing circuit 376 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. RX processing circuit 376 transmits the processed baseband signal to controller / processor 378 for further processing.
[0097] 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. TX processing circuit 374 encodes, multiplexes and / or digitizes outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 372a-372n receive the outgoing processed baseband or IF signal from TX processing circuit 374 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.
[0098] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of backward channel signals through the RF transceivers 372a-372n, the RX processing circuit 376 and the TX processing circuit 374 according to well-known principles. The controller / processor 378 can also support additional functions, such as higher-level wireless communication functions. For example, the controller / processor 378 can perform a Blind Interference Sensing (BIS) process such as that performed through a BIS algorithm, and decode a received signal from which an interference signal is subtracted. A controller / processor 378 may support any of a variety of other functions in gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.
[0099] The controller / processor 378 is also capable of executing programs and other processes residing in the memory 380, such as a basic OS. The controller / processor 378 can also support channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTCs. The controller / processor 378 can move data into or out of the memory 380 as required by an execution process.
[0100] The controller / processor 378 is also coupled to the backhaul or network interface 382. The backhaul or network interface 382 allows gNB 102 to communicate with other devices or systems through a backhaul connection or through a network. The backhaul or network interface 382 can support communication over any suitable wired or wireless connection(s). For example, when gNB 102 is implemented as a part of a cellular communication system, such as a cellular communication system supporting 5G or new radio access technology or NR, LTE or LTE-A, the backhaul or network interface 382 can allow gNB 102 to communicate with other gNBs through wired or wireless backhaul connections. When gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow gNB 102 to communicate with a larger network, such as the Internet, through a wired or wireless local area network or through a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication through a wired or wireless connection, such as an Ethernet or an RF transceiver.
[0101] The memory 380 is coupled to the controller / processor 378. A part of the memory 380 can include an RAM, while another part of the memory 380 can include a flash memory or other ROMs. In certain embodiments, a plurality of instructions, such as the BIS algorithm, are stored in the memory. The plurality of instructions are configured to cause the controller / processor 378 to execute the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.
[0102] As will be described in more detail below, the transmission and reception paths of gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuit 374 and / or RX processing circuit 376) support aggregated communication with FDD cells and TDD cells.
[0103] Although Figure 3b illustrates an example of gNB 102, various changes may be made to Figure 3b. For example, gNB 102 can include any number of each component shown in Figure 3a. As a specific example, the access point can include many backhaul or network interfaces 382, and the controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as including a single instance of the TX processing circuit 374 and a single instance of the RX processing circuit 376, gNB 102 can include multiple instances of each (such as one for each RF transceiver).
[0104] The exemplary embodiments of the present disclosure are further described below in conjunction with the accompanying drawings.
[0105] The text and drawings are provided as examples only to help readers understand the present disclosure. They are not intended and should not be interpreted as limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, based on the content disclosed herein, it is obvious to those skilled in the art that modifications to the illustrated embodiments and examples can be made without departing from the scope of the present disclosure.
[0106] The specification agreement in this article can be understood as a direct agreement in the specification or an indirect agreement (for example, clarifying mapping relationships through signaling interaction).
[0107] [Specific embodiments of the present invention will begin below]
[0108] In the communication network, Power Class (referred to as PC) is a commonly used way to classify User Equipment (referred to as UE) based on the transmit power capacity. UEs with different power classes have different transmit power capabilities, that is, the maximum power they can transmit is different. Among different power classes, power class 3 (PC3) is the default power class of the UE, and UEs that support other power classes higher than the transmit power corresponding to PC3 are called High Power User Equipment (referred to as HPUE).
[0109] For user equipment used close to the human body, its transmit power is also limited by laws and regulations from various countries or regions in practical applications. Among them, Specific Absorption Rate (SAR) and Absorbed Power Density (APD) or Incident Power Density (IPD) are currently commonly used metrics for measuring the electromagnetic radiation impact of UE on the human body due to the transmit power. In order to keep the electromagnetic radiation impact of UE on the human body within a safe value, i.e. to meet the regulatory requirements for the above-mentioned metrics, the transmit power of the UE often needs to be reduced.
[0110] Non-terrestrial Network (NTN) is a new network form, which requires UE to transmit uplink transmit power on the ground to communicate with satellites in different orbit altitudes. Due to the longer communication distance, its power required for uplink is higher than other Terrestrial Networks (TN). Therefore, applying HPUE in NTN scenario is an important solution to improve and strengthen NTN network uplink.
[0111] At this time, the conflict between the high transmit power of HPUE and the electromagnetic radiation regulations to protect user safety is an urgent problem to be resolved.
[0112] Various embodiments of the present disclosure provide a method performed by a user equipment (UE) in a communication system, comprising: transmitting first information to a network side, wherein the first information includes: first uplink time ratio information, and / or fourth information, wherein the first uplink time ratio information is associated with a time ratio of a maximum uplink transmission corresponding to a highest power class supported by the UE; the fourth information is associated with that the UE has an 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 second uplink time ratio information for the UE, and the sixth information includes configuration information related to transmit power reduction of the UE; determining the transmit power reduction value of the UE based on the first information, or based on the first uplink time ratio information and the information associated with the second uplink time ratio information, or based on the sixth information.
[0113] The method performed by the user equipment (UE) in the communication system provided by Various embodiments of the present disclosure determines the transmit power reduction value of the UE as a transmit power reduction value (which can also be 0. For details, please refer to the subsequent implementation) determined based on the first information, or based on the first uplink time ratio information and the information associated with the second uplink time ratio information, or based on the sixth information, rather than a fixed power reduction value corresponding to the power class. It is more flexible, so that the HPUE can maintain the transmit power corresponding to its high power class as much as possible, while ensuring that the HPUE can comply with electromagnetic radiation regulatory requirements.
[0114] Step S401, UE transmits first information to a network side.
[0115] The first information should include the highest power class supported by the UE, and the maximum uplink transmission time ratio information corresponding to the highest power class (also referred to as the first time ratio information, the first uplink time ratio information, the first uplink occupation ratio (or uplink duty cycle or uplink duty ratio or uplink ratio), or other similar names, which are not limited in any way by this disclosure and can be used interchangeably). The specific value of the time ratio information contained in the first information should ensure that the HPUE meets the corresponding electromagnetic radiation regulations when transmitting in accordance with the reported uplink occupation ratio at the highest power class reported by the HPUE, taking into account the specific design and production implementation of the UE at the corresponding power class. The specific generation method of this numerical value is not limited here.
[0116] The highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class contained in the first information can be reported to the network by adding a new IE to the existing Information Element (IE) in the UECapabilityInformation message (which is a response to the UECapabilityEnquiry message)) or adding a new IE to the UECapabilityInformation message.
[0117] Similarly, the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class contained in the first information can also be reported to the network by adding IEs or modifying existing IEs in other messages.
[0118] Herein, the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class contained in the first information can be indicated by two elements in one IE, or can be indicated by the name of the IE and one element it contains respectively.
[0119] When the first information includes the first time, similarly, the first time, the highest power class supported by the UE, and the maximum uplink transmission time ratio information corresponding to the highest power class can be indicated by three elements in one IE respectively, or indicated by the name of the IE and the multiple elements it contains respectively.
[0120] For example, when the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class contained in the first information are implemented by adding a new IE to the existing RF-Parameters IE in the UECapabilityInformation message, assuming that the name of the new IE is ntn-HPUEConfig, the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class contained in the first information can be indicated by the multiple elements within the new IE respectively. For example, the element ntn-powerClass included in ntn-HPUEConfig can be used to indicate the highest power class supported by the UE; the maximum uplink transmission time ratio information corresponding to the highest power class can be indicated by the element ntn-maxUplinkRatio contained in ntn-HPUEConfig. When the first information includes the first time, the first time may be indicated by the element ntn-uplinkConfigTime included in ntnHPUEConfig.
[0121] For another example, in the case that the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class contained in the first information are based on the name of the newly added IE and the multiple elements contained therein respectively, when the newly added IE name is ntn-maxUplinkRatio-PC2, the newly added IE name is used to indicate the highest power class supported by the UE (for example, here, Power Class 2 (PC2 for short)), and the element contained in the IE can indicate the maximum uplink transmission time ratio information corresponding to the highest power class. For other high power classes, such as Power Class 1.5 (PC1.5 for short) and Power Class 1 (PC1 for short), similar IEs can also be applied, such as ntn-maxUplinkRatio-PC1dot5 and ntn-maxUplinkRatio-PC1 etc. When the first information includes the first time, the name of the newly added IE may be ntn-HPUEConfig-PC2, and the name of the newly added IE ntn-HPUEConfig-PC2 is used to indicate the highest power class supported by the UE (for example, here, Power Class 2 (PC2 for short)), two elements included in this IE may respectively indicate the maximum uplink transmission time ratio information corresponding to the highest power class (for example, ntn-maxUplinkRatio) and the first time (for example, 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 mentioned above can also be applied, such as ntn-HPUEConfig-PC1dot5 and ntn-HPUEConfig-PC1, etc.
[0122] Optionally, in addition to including the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class, the first information may also include the first time. The first time is the validity time, or duration, of the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class. That is, the first time can be used to report to the network the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class are valid within the first time.
[0123] The first time contained in the first information can be reported to the network by reporting a specific time length (such as value X) and combining it with the corresponding time unit (such as milliseconds (ms), seconds (s), microseconds (us), slot (slot), symbol (symbol), subframe (sub frame, SF), frame (frame), etc.)
[0124] As an implementation manner, determining the highest power class supported by the UE and the valid time of the first uplink time ratio information can also be achieved by including the first capability information in the first information. The first capability information is used to report to the network that the UE has the ability to dynamically configure the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class. For example, the UE transmits the first information for the first time, and the first information includes the first capability information, the supported highest power class, and the first uplink time ratio information (it can be understood that the first information does not include the first time). After at least one of the supported highest power class and the first uplink time ratio information is updated, the UE transmits the first information for the second time, and the first information includes the first capability information, the supported highest power class and the first uplink time ratio information. In this implementation, the determined validity time of the supported highest power class and the first uplink time ratio information included in the first information transmitted for the first time is determined as the difference between the time when the first information is received for the second time by the network minus the time when the first information is received for the first time.
[0125] If the first time contained in the first information is implemented by a specific time length, when the network does not receive new first information when the specific time length of the first time ends, it is considered that the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class indicated in the first information at last time transmitted by the UE to the network are still applicable. Similarly, if the first time is implemented by reporting the first capability information, when the network does not receive the updated maximum power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the maximum power class, the originally reported maximum power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the maximum power class are still applicable.
[0126] Herein, the UE can use the newly transmitted first information to update the highest power class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class contained in the last transmitted first information, or only update any one of them.
[0127] If the first time is implemented by reporting the first capability information, the first capability information can be implemented by adding the elements included in the newly added IE (such as ntn-HPUEConfig or ntn-HPUEConfig-PC2, etc.) in the above example. For example, when the element name corresponding to the first capability information is 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 class supported by the UE and the maximum uplink transmission time ratio information corresponding to the highest power class.
[0128] Step S402, the network transmits second information to the UE.
[0129] The second information may include information associated with second uplink time ratio information for the UE, wherein the second uplink time ratio information (may also be referred to as second uplink time ratio information, second uplink occupation ratio, or other similar names, which are not limited in any way by this disclosure and can be used interchangeably) may be determined based on information associated with the second uplink time ratio information of the UE.
[0130] As an above method, the second information may include but is not limited to one or more of the following:
[0131] -ratio information in time of the uplink resources integrally configured by the network (for example, the ratio information may be the second ratio);
[0132] -activated time ratio information configured by the network for the serving cell of the UE (for example, the ratio information may be a third ratio);
[0133] -activated time ratio information configured by the network for the beam where the UE is located (for example, the ratio information may be a third ratio);
[0134] - ratio information in time of uplink resources configured by the network for the serving cell of the UE (for example, the ratio information is related to the values of the second ratio and the third ratio);
[0135] - ratio information in time of the uplink resources configured by the network for the beam where the UE is located (for example, the ratio information is related to the values of the second ratio and the third ratio);
[0136] - ratio information in time of uplink resources configured individually by the network for the UE (for example, the ratio information is related to the values of the second ratio and the third ratio).
[0137] The above-mentioned second information can be broadcast by the network to all UEs in the cell through a System Information Broadcast (SIB) message, instead of being transmitted to a certain UE individually. It can also be configured to each UE through Medium Access Control (MAC for short) or Radio Resource Management (RRC for short) messages. When it is configured to each UE, different UEs can be configured with the same uplink ratio information, or different UEs can be configured with different uplink ratio information.
[0138] The ratio information contained in the above second information can be indicated by a numerical value. For example, the network can agree to indicate a numerical value related to the ratio such as 10%, 0.1, 10, etc., to indicate that the ratio is 10%. It can also be agreed that after some specific ratio values are numbered, the network will indicate the ratio information by indicating the numbers. For example, it can also be agreed that 5%, 10%, and 15% are numbered 1, 2, and 3 respectively, and in the case, the network indicates that the ratio information is 5% by indicating number 1.
[0139] In the above second information, the ratio in time of the uplink resources integrally configured by the network may be the ratio of time resources used as uplink communication configured by the network for all cells and / or beams served in the current working frequency band, among the available time resources.
[0140] For an NTN network, the ratio in time of the uplink resources integrally configured by the network can be expressed by the position (number) or number and period information of the configured uplink time resources within the agreed uplink resources.
[0141] For example, the uplink time ratio information configured by the current network can be indicated to the UE by transmitting N time units (such as slots, symbols, subframes, frames, etc.) used to indicate the configuration cycle period and M time units configured for uplink communication in the period. As an example, N and M can be transmitted separately by using elements in the message.
[0142] In addition, the time resources indicating the configuration cycle period (N time units in the above example) or the time resources configured for uplink communication in the period (M time units in the above example) can be determined in an agreed manner. For example, when the specification agrees that the cycle period corresponding to the uplink configuration indicated by the network is 10 subframes by default, as an example, the element name indicated by the network at this time may be uplinkSFNin10SFN (N = 10 and the time unit is subframe (SF)), that is, the cycle period corresponding to the agreed uplink configuration is embodied by the element name. The content carried by this element is used to indicate the time resource configured for uplink communication (M in the above example). As another example, the cycle period corresponding to the agreed uplink configuration can also be implicitly embodied, that is, after the agreement is agreed, the time resources of the configuration cycle period (N time units in the above example) are no longer indicated or indicated by the element name or a separate element. At this time, the network only needs to indicate the time resources configured for uplink communication (M in the above example).
[0143] Similarly, the time resources indicating the configuration cycle period (N time units in the above example) or the time resources configured for uplink communication in the period (M time units in the above example) can also be in a manner that agrees time resources configured for uplink communication in the period. For example, when the specification agrees that the time resources configured for uplink communication in each period are 2 consecutive subframes (that is, in the above example, M is 2 at this time and the time unit is a subframe), the network only needs to indicate the time information of the cycle period (N time units in the above example). At this time, the agreed time resources configured for uplink communication in each period can be explicitly embodied in the message, or implicitly embodied through specification agreements.
[0144] For another example, when the time units (such as slots, symbols, subframes, frames, etc.) in the time resources of the configuration cycle period are numbered through agreement, for example, when the network agrees through issuance or specification that the cycle period is 10 subframes, these 10 subframes in each period can be numbered as subframe number 0 (SFN0) to subframe number 9 (SFN9), at this time, the uplink time ratio information configured by the current network can be determined by the network indicating the agreed time resource (here, the subframe number) configured for uplink transmission in the period. As an example of this method, in this example, when the network indicates subframe numbers configured for uplink transmission as SFN0 and SFN5, the indicated information is that in the predetermined ten subframes from SFN0 to SFN9, and the subframe number 0 and subframe number 5 are configured for uplink transmission. At this point, it 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 method, the uplink configuration method of subframe numbers 0 and 5 configured for uplink transmission in the period of subframe numbers 0 to 9 in the previous example can also be agreed in advance as a pattern, and by agreeing on the number of the pattern (such as uplink configuration pattern 1), at this time, the network can indicate the pattern number, such as the uplink configuration pattern 1, to indicate the uplink time ratio configured by the current network.
[0145] For another example, the agreed uplink scheduling pattern with number 2 may be: the first subframe (when the time unit is agreed to be a subframe) is an uplink subframe, the second, third, and fourth subframes are non-uplink subframes, and the fifth subframe is an uplink subframe, sixth, seventh, and eighth subframes are non-uplink subframes, repeat the process . In this example, the uplink ratio of the uplink scheduling pattern with number 1 is 25% or 1 / 4. At this time, the network can indicate to the UE that the current network uses the uplink scheduling pattern by indicating a number in the second information. For example, when the second information indicates an uplink scheduling pattern with number 2, it means indicating to the UE that the uplink ratio of the current network configuration is 25%.
[0146] As mentioned above, the second information may also include activated time ratio information configured by the network for the serving cell of the UE and / or activated time ratio information configured by the network for the beam where the UE is located. Depending on the deployment of the network, for example, when a satellite serves multiple cells or multiple beams, it can take turns to serve the service range of the satellite by serving different cells or beams at different times. This way to take turns to serve can be done in a uniform manner, that is, the uplink ratio of all cells or beams served by the satellite is the same, or it can be done in a non-uniform manner, that is, the uplink ratio of all cells or beams served by the satellite is different. At this time, the serving cell of the UE or the beam where the UE is located can be in different activation ratios, and the UE can only perform uplink and / or downlink services when the current serving cell or beam is activated by the network. Similarly, this ratio information can be indicated through the aforementioned multiple expressions (for example, through the aforementioned numerical form, pattern number, etc.), the difference being that when indicating the activated time ratio information configured by the network for the serving cell of the UE and / or the activated time ratio information configured by the network for the beam where the UE is located, the network should indicate the time ratio that the current serving cell or beam is activated, the number of time units, the pattern or its number or other expressions listed above, etc.
[0147] For example, when the aforementioned numerical expression is used, similarly, when the ratio information configured by the network that the cell or beam where the UE is located is activated can be a numerical value or a percentage, for example, the information name can be beamActivateRatio, then the value of the information can be a numerical value less than or equal to 1. For example, when the numerical value is 0.25, it means that the ratio information configured by the network that the cell or beam where the UE is located is activated is 25%. The value of this information may also be a numerical value less than or equal to 100. For example, when the value is 35, it means that the uplink time ratio information of the cell or beam where the UE is located configured by the network is 35%.
[0148] In addition, the activated time ratio information of the UE configured by the serving cell and / or the activated time ratio information configured by the network for the beam where the UE is located can also be indicated by priority (such as high, medium, low, etc.) or in the form of priority number (such as 1, 2, 3, 4, etc.). When this method is used, the mapping relationship between priority and the above-mentioned multiple expressions needs to be agreed. For example, when the agreed priority is high and its corresponding activation ratio is 20%. When the network indicates that the priority that the current cell or beam is activated is high, it means indicating the activated time ratio is 20%. The activated ratio in this example is 20%, but can also be indicated by other expressions mentioned above. When other expressions are used, similarly, it is necessary to agree on the mapping relationship between the priority and a group of periods and the number of times activated therein, or the mapping relationship between the priority and an agreed activated pattern, or the mapping relationship between the priority and a pattern number, etc.
[0149] As mentioned above, the second information may also include the ratio information in time of uplink resources configured by the network for the serving cell of the UE and / or ratio information in time of the uplink resources configured by the network for the beam where the UE is located and / or the ratio information in time of uplink resources configured individually by the network for the UE. At this time, this information is different from the above-mentioned ratio in time of the uplink resources integrally configured by the network, which is the uplink ratio configured by the network for the serving cell or beam where the UE is located. It can be determined by the network in combination with its activated ratio of the serving cell or beam where the UE is located and the ratio of the uplink resources integrally configured by the network and then indicated to the UE. At this time, the ratio information is determined by the network itself. Similarly, this ratio information can be indicated through the aforementioned multiple expressions, the difference being that when indicating the ratio information in time of uplink resources configured by the network for the serving cell of the UE and / or ratio information in time of the uplink resources configured by the network for the beam where the UE is located and / or the ratio information in time of uplink resources configured individually by the network for the UE, the network should indicate the configured uplink time ratio of the current serving cell or beam or the current UE, the number of time units, the pattern or its number or other expressions listed previously, etc.
[0150] Among them, the ratio information in time of uplink resources configured by the network for the serving cell of the UE or ratio information in time of the uplink resources configured by the network for the beam where the UE is located or the ratio information in time of uplink resources configured individually by the network for the UE can also be determined by combining other information contained in the second information. For example, when the second information includes both the ratio information in time of the uplink resources integrally configured by the network (for example, X or Xth ratio, etc.) and the activated time ratio information configured by the network for the beam (or its serving cell) where the UE is located (for example, Y or Yth ratio, etc.), at this time, the time ratio information of the uplink resources configured by the network for the beam (or its serving cell) where the UE is located can be determined by X and Y jointly.
[0151] One way to determine this is to convert the ratio information X and Y into the percentage values indicated by them with reference to the various aforementioned expressions corresponding to them, at this time, the ratio information in time of the uplink resources configured by the network for the beam (or its serving cell) where the UE is located is the product of the percentage values indicated by X and Y.
[0152] In addition, consider that the following situation may occur in actual network deployments, that is, although the activated ratio (Y) is set and indicated for the current serving cell or beam, the duration of a single activation may close to or exceed the time required for the electromagnetic radiation regulations to evaluate the electromagnetic radiation of UE. At this time, within the time when the UE is activated for a single time, from the perspective of electromagnetic radiation regulations, it may be considered that the duration of its emission (or uplink transmission) is long enough, that is, its regulatory requirements for uplink emission or electromagnetic radiation are not affected by the activated ratio (Y) of the current serving cell or the located beam. At this time, when considering this situation, another decision method may be that the ratio information in time of the uplink resources configured by the network for the beam (or its serving cell) where the UE is located is the ratio information in time of the uplink resources integrally configured by the network (X), That is, at this time, the activated time ratio information (Y) configured by the network for the beam (or its serving cell) where the UE is located is not considered.
[0153] The second information is intended to indicate to the UE the ratio in time of resources configured in the current network that can schedule the UE for uplink transmission. It is expressed by different types of expressions for the second information in this disclosure, the expression form is not limited to a numerical value of a ratio, and it can also be one of the aforementioned expressions, or other forms.
[0154] Optionally, in addition to the ratio in time of resources configured in the current network that can schedule the UE for uplink transmission indicated to the UE (ie, the uplink time ratio information configured by the current network), the second information may also include the valid time (second time) corresponding to the uplink time ratio information. As an implementation manner, if the first information includes the first time, the second time included in the second information may be the same as the first time.
[0155] Step S403: the transmit power of the UE is determined based on the first information and the second information.
[0156] 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 transmit power corresponding to the current power class, that is, there is no need to reduce or fall back the transmit power for electromagnetic radiation regulations.
[0157] When the first time ratio information is smaller than the second time ratio information, the UE can determine its transmit power in one or a combination of the following methods.
[0158] Method 1: The transmit power of the UE is reduced or backed off according to the first time ratio information (such as X%) and the second time ratio information (such as Y%), wherein the reduced or backed off power value is based on the first time ratio information (such as X%) and the second time ratio information (such as Y%) are calculated. As an implementation manner, the transmit power of the UE is obtained by reducing the transmit power P_powerclass corresponding to its supported power class by 10*log10 (Y / X) dB, or the transmit power is reduced to P _ powerclass-10 * log10 (Y / X) dBm. It can be understood that 10 * log10 (Y / X) dB is only an example of a reduced or backed-off power value, and is not a limitation of the present disclosure.
[0159] Considering that in practical applications, the above-mentioned reduced or backed-off power value may be a decimal through mathematical calculation. At this time, the effective digits of the decimal can also be agreed to be 1 or rounded up or an integer multiple of the agreed step size. For example, when the second ratio information is 25% and the first ratio information is 15%, the reduced or backed-off power value 10 * log10 (25 / 15) can be 2.2 (agreed to be 1 significant digit) or 3 (agreed to be rounded up) or 2.5 (agreed to be rounded up an integer multiple of 0.5 (step size)), etc.
[0160] Considering the multiple expression methods of the aforementioned first ratio information and second ratio information, when these ratio information is reported or issued from some agreed specific ratio values in the form of numbers, etc., the above calculation or value taking method can be implicitly embodied. The reduced or backed-off power value at this time can be expressed as being determined by a combination of the numbers of the first ratio information and the second ratio information.
[0161] For example, when the first ratio information is reported through a number by selecting from 10% and 15%, and its corresponding number is 0 and 1 (Table 1 below), and the second ratio information is reported by selecting from 10% and 20% and its corresponding number is 0 and 1 (Table 2 below), the reduction value can be determined by the reporting number of the first ratio information and the indicating number of the second ratio information in Table 3 below. Among them, the power value of the transmit power reduction or backoff in Table 3 is determined by the aforementioned method (10 * log10 (Y / X)), but it is only invisible in this expression. The table is only a way of showing the value and the reporting number of the first ratio information and the reporting number of the second ratio information, and is not limited to expressions in text or other ways.

[0166] Table 3 Reduced or Reduction Power Values
[0167]
[0168] Method 2: The UE's transmit power is not reduced or backed off, that is, the UE performs the transmission according to the transmit power corresponding to its power class. At this time, the UE can use one or a combination of the following methods to maintain its transmit power at the high power class.
[0169] Method 2-1: The UE enters the uplink transmission suspension state (also called the first state, or other similar names, which are not limited in any way by this disclosure and can be used interchangeably) to reduce its uplink transmission ratio within a certain period of time.
[0170] When this is applied, the first information may include fourth information, and the fourth information is intended to inform the network that the UE's ability to support the uplink transmission suspension (which may also be referred to as the second capability, which is not subject to any limitation in this disclosure, and can be used interchangeably). The UE reporting this fourth information can maintain its transmit power at the high power class and cope with electromagnetic radiation regulations by the uplink transmission suspension.
[0171] This fourth information may be reported in a manner similar to the first information, or may be included in the first information. For example, when the fourth information is included in the first information, as one of the above methods, the element name indicating the fourth information may be ntn-hpue-tx-gap, and the element indicating the fourth information may be included the above-mentioned ntn-HPUEConfig or ntn-HPUEConfig-PC2 and other IEs in the previous example.
[0172] For a UE that supports the second capability, it can monitor its emission power and emission time within a certain time (for example, the third time, which can also be called the second preset time period) under the condition of meeting the requirements of electromagnetic radiation by itself based on its own design and implementation, When the uplink transmission duration scheduled by the UE during the third time will be greater than or equal to the transmission duration it considers safe (also referred to as the first preset transmission duration), or when the uplink transmission duration scheduled by the UE during the third time will be greater than or equal to the uplink transmission duration corresponding to the first time ratio information, the UE transmits the third information to the network and suspends its uplink transmission starting from the fifth time after transmitting the third information. The third information here is intended to report to the network that it suspends its uplink transmission starting from the fifth time after sending the third information.
[0173] The fifth time is the start time when the UE suspends its uplink transmission after reporting the third information to the network. The fifth time is a time determined in a preset manner. For example, a preset method of the fifth time may be to agree that the fifth time is the next time unit of the time unit (slot, symbol, subframe, frame, etc.) in which the UE transmits the third information.
[0174] For example, when the fifth time is agreed to be the next slot of the slot where the UE transmits the third information (the time unit in this example is a slot), after the UE transmits the third information to the network, the UE should start from the next slot after the slot where the third information is located, or the UE should start from the first symbol of the next slot after the slot where the third information is located, and no uplink transmission is performed.
[0175] When the UE enters the uplink transmission suspension state, or when uplink transmission is suspended, the UE should stop its transmission on uplink transmission channels including but not limited to PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel), SRS (Sounding Reference Signal), etc. However, during the period when the UE suspends uplink transmission, or when the UE is in the uplink transmission suspension state, the UE's downlink reception and measurement on the downlink channel are not affected.
[0176] The third information may include the above-mentioned fourth time (which may also be called the first time period), wherein the fourth time is the length of time that the UE will suspend its uplink transmission starting from the fifth time after transmitting the third information to the network, or it is called the length of time that it will be in the first state (for example, or it can be a state to enter stopping uplink transmission) after the UE transmits the third information to the network. The fourth time can be expressed numerically, and its unit can be millimeters, seconds, slots, symbols, subframes, frames, etc. The fourth time can also be implicitly expressed in an agreed manner, that is, when the UE is agreed to transmit the third information to the network, the corresponding fourth time is agreed by the specification as W milliseconds, seconds, slots, symbols, subframes, frames, etc. When expressed implicitly, the third information at this time does not need to contain the specific value of the fourth time.
[0177] For example, when the UE reports to support ntn-hpue-tx-gap (the capability indicated by the fourth information, for example, the second capability), after the UE reports the third information (that is, the information indicating that it enters the uplink transmission suspension state, for example, ntn-hpue-tx-gap-on) and the third information includes the fourth time (for example, ntn-hpue-tx-gap-time), the UE should stop its uplink transmission within the fourth time reported by it (e.g., ntn-hpue-tx-gap-time) starting from the first symbol (fifth time) of the next slot after the slot in which it reports the third information, and its transmit power should meet the requirements of Transmit OFF power during this fourth time. Also, the UE should be ready for uplink transmission before the end of the fourth time. This expression is intended to ensure that within the fourth time described in Method 2-1, the UE enters the uplink transmission suspension state and turns off the uplink transmission. And this expression can ensure that the UE resumes uplink transmission at any time after the end of the fourth time, that is, the UE should be ready for uplink transmission before the end of the fourth time.
[0178] For another example, when the UE reports to support ntn-hpue-tx-gap (the capability indicated by the fourth information, for example, the second capability), after the UE reports the third information (that is, the information indicating that it enters the uplink transmission suspension state, for example ntn-hpue-tx-gap-on) and assuming that the fourth time is agreed to be 10 subframes later, the UE stops its uplink transmission within 10 subframes starting from the next subframe (the fifth time) after the subframe in which the slot in which its reported ntn-hpue-tx-gap-on is located is located, and its transmit power should meet the requirements of Transmit OFF power during this fourth time. Also, the UE should be ready for uplink transmission before the end of the fourth time.
[0179] Optionally, when the third information (for example, ntn-hpue-tx-gap-on) does not include the above-mentioned fourth time (or first time period), and the fourth time is not agreed in the above-mentioned implicit manner, the UE suspends its uplink transmission until the UE transmits 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 transmitted by the UE to the network to indicate the end of its uplink transmission suspension or to exit the uplink transmission suspension state, so that the network can resume its uplink scheduling for the UE.
[0180] For example, when the UE reports to support ntn-hpue-tx-gap (the capability indicated by the fourth information, for example, the second capability), the UE reports the third information (i.e., information indicating that it enters the uplink transmission suspension state, for example, ntn-hpue-tx-gap-on), the UE stops its uplink transmission from the next subframe (fifth time) after the subframe in which the slot in which it reports ntn-hpue-tx-gap-on is located, until the UE transmits the seventh information (ntn-hpue-tx-gap-off). For a UE that reports to support ntn-hpue-tx-gap (the capability indicated by the fourth information, for example, the second capability), after reporting the third information (for example, ntn-hpue-tx-gap-on) and before reporting the seventh information (ntn-hpue-tx-gap-off), its transmit power should meet the requirements of Transmit OFF power. During this period, the UE should stop its transmission on uplink transmission channels including but not limited to PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel), SRS (Sounding Reference Signal), etc. However, during the period when the UE suspends uplink transmission, or when the UE is in the uplink transmission suspension state, the UE's downlink reception and measurement on the downlink channel are not affected.
[0181] Method 2-1 can also be indicated to start through the third information (for example, ntn-hpue-tx-gap-on), and additionally include a period configuration of transmission interruption through the eighth information.
[0182] For example, the eighth information may include that the UE performs uplink transmission in the first y time units in every x time units in the future (such as milliseconds, seconds, slots, symbols, subframes, frames, etc.) after the start of the third information indication. On the contrary, the eighth information can also include that UE does not perform uplink transmission in the first y time units in every x time units in the future (such as milliseconds, seconds, slots, symbols, subframes, frames, etc.) after the start of the third information indication. No uplink transmission is performed. On the time unit configured in the eighth information that does not perform uplink transmission, the UE should stop its transmission on uplink transmission channels including but not limited to PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel), SRS (Sounding Reference Signal), etc. However, the UE's downlink reception and measurement on the downlink channel are not affected.
[0183] The eighth information may be included in the fourth information and reported to the network by the UE at the same time as reporting that it has the second capability. At this time, after the UE reports the third information, the UE should perform the transmission interruption period configuration reported in the eighth information, starting from the fifth time.
[0184] The eighth information may also be included in the third information. At this time, after the UE reports the third information (including the eighth information), the UE should perform the transmission interruption period configuration reported in the eighth information, starting from the fifth time.
[0185] Similarly, this periodic interruption configuration (indicated by the eighth information), the UE needs to perform this transmission interruption configuration starting from the fifth time after transmitting the third information, until the end of the fourth time (when the UE reports the fourth time) or until the UE transmits the seventh information (when the UE does not report the fourth time and indicates the stop / exit of the interrupt state using the aforementioned seventh information). The UE needs to be prepared to resume its normal uplink transmission before the end of this interruption configuration, that is, to resume to an uplink transmission state that can be continued without interruption.
[0186] For example, in case that the eighth information is included when the UE reports to support ntn-hpue-tx-gap (the capability indicated by the fourth information), assuming that the interruption period configured by the eighth information is the first 4 subframes of every 10 subframes for uplink transmission, after the UE reports the third information (that is, the information indicating it to enter the uplink transmission suspension state, such as ntn-hpue-tx-gap-on), the UE should meet the requirements of the Transmit OFF power (Transmit OFF power) in the last 6 subframes of every 10 subframes starting from the next subframe after the subframe in which it reports the third information (within the time unit in which uplink transmission is not performed). This expression is intended to ensure that during the interruption time indicated by the eighth information in this configuration, the UE enters the state where the uplink transmission is suspended and turns off the uplink transmission.
[0187] The uplink transmission suspension in method 2-1 can also be carried out in combination with the aforementioned power class reduction method, that is, within the fourth time after the UE reports the third information, its transmit power should be backed off to an agreed power class, such as to the transmit power of power class 3 (PC3), from the high power class it supports.
[0188] Method 2-2: The UE discards (also called dropping, skipping, etc.) uplink transmission occasions according to a certain ratio (also called the first ratio) to reduce its actual uplink transmission time ratio.
[0189] The UE decides the uplink transmission occasions it drops based on the first time ratio information (such as X%) and the second time ratio information (such as Y%), combined with the actual uplink scheduling situation. In this method 2-2, the UE and the network agree through agreement that they are allowed to drop a maximum number of uplink transmission times or uplink transmission occasions not exceeding (1-X / Y) %.
[0190] When the first information contains the first time and the second information contains the second time, that is, when the first time and the second time are applied at the same time, then the behavior of dropping uplink transmission and its allowed ratio in this method should be limited to within the validity time, i.e. the first time or the second time. That is, the behavior of dropping uplink transmission and its allowed ratio are valid within the first time or the second time. As a way of the above, the first time and the second time under this condition should be equal.
[0191] When the first information contains the first time or the second information contains the second time, that is, when the first time and the second time are applied separately, then the behavior of dropping uplink transmission and its allowed ratio in this method should be limited to within the applied first time or second time, that is, the behavior of dropping uplink transmission and its allowed ratio are valid within the first time or second time.
[0192] When this method 2-2 is applied, the first information may include fifth information, and the fifth information is intended to tell the network that the UE supports the capability of dropping uplink transmission occasions according to a certain ratio (also referred to as the third capability)., this disclosure does not impose any restrictions on this and can be used interchangeably). The UE that reports the fifth information can maintain its transmit power of the high power class and respond to electromagnetic radiation regulations through method 2-2.
[0193] For example, when the fifth information is included in the first information, as one of the above methods, the element name indicating the fifth information may be ntn-hpue-tx-drop, and the element indicating the fifth information may be included in IE such as ntn-HPUEConfig or ntn-HPUEConfig-PC2 described in the previous example.
[0194] As another implementation manner, the second time ratio information may not be indicated to the UE through messages such as SIB, MAC, and RRC in the aforementioned second step. For example, after the UE transmits the first information to the network, the network may transmit sixth information to the UE based on the first information, to indicate the configuration of its transmit power to the UE.
[0195] The sixth information here may include one or more of the following to indicate the UE to configure its transmit power:
[0196] (1) information related to the power that the UE needs to fall back, for example, the power value (dB) that the UE needs to fall back;
[0197] (2) information related to whether the UE needs to fall back to the next power class, for example, whether the UE needs to fall back a power class, that is, whether it needs to fall back to the next lower power class. For example, power class 2 falls back to power class 3, power class 1.5 falls back to power class 2, etc.;
[0198] (3) information related to the target power class to which the UE needs to fall back, for example, the target power class to which the UE needs to fall back.
[0199] When the UE power configuration method indicated by the sixth information is agreed in the specification, whether the sixth information is received can also be used as an indication for the UE to configure its transmit power. For example, when the specification agrees that the UE receives the sixth information, assuming that the sixth information is ntn-hpue-tx-fallback, the transmit power of the UE needs to be fell back to the next lower power class. At this time, after the UE receives ntn-hpue-tx-fallback, it performs power reduction according to the agreed method. When the UE does not receive ntn-hpue-tx-fallback, it maintains the transmit power corresponding to its power class for transmission.
[0200] Similarly, when the UE power configuration method indicated by the sixth information is agreed through the specification, the sixth information may also use 0 or 1 to indicate whether the UE performs power configuration in the agreed manner. For example, assuming that the sixth information is ntn-hpue-tx-fallback, when the specification agrees that the UE receives ntn-hpue-tx-fallback as 1, the UE's transmit power needs to fall back to the next lower power class; When the UE receives ntn-hpue-tx-fallback as 0, it maintains the transmit power corresponding to its power class for transmission. When this method is applied, the numbers contained in the sixth information, such as 0, 1, 2..., can also be mapped with the different power configuration methods of the UE indicated in the above sixth information. In this manner, the UE performs corresponding transmit power configuration according to the number contained in the sixth information it receives.
[0201] The power configuration in the method can be expressed as follows.
[0202] The configuration formula for transmit power is as follows:
[0203] The UE is allowed to set its configured maximum output power PCMAX, f, c on each slot for carrier f and serving cell c. This configured maximum output power PCMAX, f, c is set within the following range:
[0204] PCMAX L, f, c PCMAX, f, c PCMAX H, f, c
[0205] PCMAX L, f, cis the lower limit of the range, PCMAX _ L, f, c= MIN {PEMAX, c- TC,c, (PPowerClass- PpowerClass + PPowerBoost)-MAX (MAX (MPRc + MPRc, A-MPRc) + TIB, c + TC, c + TRxSRS, P-MPRc)}
[0206] PCMAX_H,f,cis the upper limit of the range, PCMAX_H,f,c= MIN { PEMAX,c, PPowerClass- PPowerClass+ PPowerBoost}
[0207] Wherein,
[0208] PEMAX, cis the maximum transmit power of the current cell c configured by the network;
[0209] PPowerClassis the maximum UE power at the corresponding power class specified by the specification;
[0210] PPowerClassis the power reduction in dB allowed when performing the power class reduction as specified by the specification, which may be 0dB, 3dB or 6dB depending on the conditions;
[0211] PPowerBoostis the power increasing in dB allowed when performing power boosting as specified by the specification, depending on the conditions.
[0212] TC,cis the tolerance specified by the specification for a particular frequency band;
[0213] MPRc is the value of the Maximum output power reduction (MPR) specified by the specification;
[0214] MPRc is the MPR correction value specified by the specification.
[0215] A-MPRc is the value of Additional maximum output power reduction (A-MPR) specified by the specification.
[0216] TRxSRSis the power correction value specified by the specification for Sounding reference signal (SRS) transmission under specific conditions.
[0217] P-MPRc is the maximum power reduction value for power management to meet regulatory requirements such as electromagnetic radiation.
[0218] In the above configuration formula of the transmit power, PPowerClassis the power reduction value corresponding to the power class. That is, the UE can only fall back a fixed power reduction value of 3dB, or 6dB, or 0dB (i.e., no fallback) corresponding to the power class, but cannot dynamically calculate the UE's transmit power reduction value.
[0219] The transmit power reduction value of the UE determined in various embodiments of the present disclosure is not a fixed power reduction value corresponding to the power class, but is determined based on the first information, or based on the first information and the second information, or based on the first information and the sixth information, which is more flexible. Specific embodiments of PPowerClassprovided by this disclosure are described below.
[0220] (1) For method 1: the transmit power reduction value of the UE is determined based on the first information and the second information.
[0221] Method 1 in the above third step can be performed by adding corresponding power setting and reduction value to the variable PPowerClassin the above formula. The following is an expression when applying this method:
[0222] PPowerClass=
[0223] - A dB, when the maximum uplink time ratio supported by the UE reported in the first information, such as X%, is less than the uplink time ratio configured in the network indicated by the network in the second information, such as Y%. At this time, A = 10 * log10 (Y / X).
[0224] - 0 dB when otherwise.
[0225] In the above expression, the condition of PPowerClass= A dB, that is, " when the maximum uplink time ratio supported by the UE reported in the first information, such as X%, is less than the uplink time ratio configured in the network indicated by the network in the second information, such as Y%", its expression may also include multiple implementation examples and expressions of the aforementioned first information and second information, in which the above-mentioned X and Y in some expressions are directly or indirectly indicated through elements or other means, at this time, X and Y may not be explicitly embodied in the expression.
[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 network configured uplink time ratio in the second information is indicated by uplinkSFNin10SFN in the previous example, this is equivalent to indicating X = ntn-maxUplinkRatio; Y = uplinkSFNinl0SFN / 10 in the current example. Then at this time A = 10 * log10 (uplinkSFNin10SFN / (10 * ntn-maxUplinkRatio)).
[0227] The expression at this time may be as follows:
[0228] PPowerClass=
[0229] - A dB, when the ntn-maxUplinkRatio reported by the UE in the first information is less than the ratio corresponding to the uplinkSFNin10SFN indicated by the network in the second information. At this time, 10 * log10 (uplinkSFNin10SFN / (10 * ntn-maxUplinkRatio)).
[0230] - 0 dB when otherwise.
[0231] The remaining multiple implementation examples and expressions of the aforementioned first information and second information will have a corresponding impact on the expression here, but do not affect that the specific value of the power reduction is determined by the method described in Method 1. All possible expressions are not listed here.
[0232] (2) For methods 2-1 and 2-2: the transmit power reduction value of the UE is determined based on the first information.
[0233] When applying methods 2-1 and 2-2 in the third step above, the above transmit power configuration formula at this time can add conditions, that is, when the UE reports the fourth information (such as ntn-hpue-tx-gap), or when the UE reports the fifth information (such as ntn-hpue-tx-drop), and when PPowerClassand P-MPRc take 0, it is intended to indicate that the UE should perform the transmission at the transmit power corresponding to its high power class (i.e. PPowerClassin the example) without power reduction or backoff to handle regulatory indicates with electromagnetic radiation.
[0234] At this time, a definition expression of these two variables can be:
[0235] - PPowerClass=
[0236] - 0dB, when the UE reports ntn-hpue-tx-gap, or when the UE reports ntn-hpue-tx-drop, and other cases.
[0237] The remaining values of this variable follow other rules, regardless of the manner implemented here.
[0238] (3) For the sixth information, for example, when the sixth information is ntn-hpue-tx-fallback, the transmit power reduction value of the UE is determined based on the first information and the sixth information.
[0239] When ntn-hpue-tx-fallback (sixth information) includes the power value (dB) that the UE needs to fall back, then PPowerClassin the above transmit power configuration formula can be expressed as:
[0240] - PPowerClass=
[0241] - ntn-hpue-tx-fallback (dB), when the UE reports the first information (including various possible expressions of the first information) and the network indicates ntn-hpue-tx-fallback.
[0242] - 0 dB, when the UE reports the first information (including various possible representations of the first information) and the network does not indicate ntn-hpue-tx-fallback, or other situations.
[0243] When ntn-hpue-tx-fallback (sixth information) includes the target power class to which the UE needs to fall back, for example, when ntn-hpue-tx-fallback (sixth information) indicates that the target reduction class is PC3 or PC2 or PC1.5, PPowerClassin the above transmit power configuration formula can be expressed as:
[0244] - PPowerClass=
[0245] - 2 dB, when the UE reports the first information (including various possible expressions of the first information) that indicates the power class supported by the UE is PC1 and the network indicates ntn-hpue-tx-fallback as PC1.5.
[0246] - 3 dB, when the first information reported by the UE (including various possible expressions of the first information) indicates that the power class supported by the UE is PC2 and the network indicates ntn-hpue-tx-fallback as PC3; or when the first information reported by the UE (including various possible expressions of the first information) indicates that the power class supported by the UE is PC1.5 and the network indicates ntn-hpue-tx-fallback as PC2.
[0247] - 5 dB, when the first information reported by the UE (including various possible expressions of the first information) indicates that the power class supported by the UE is PC1 and the network indicates ntn-hpue-tx-fallback as PC2.
[0248] - 6 dB, when the first information reported by the UE (including various possible expressions of the first information) indicates that the power class supported by the UE is PC1.5 and the network indicates ntn-hpue-tx-fallback as PC3.
[0249] - 8 dB, when the first information reported by the UE (including various possible expressions of the first information) indicates that the power class supported by the UE is PC1 and the network indicates ntn-hpue-tx-fallback as PC3.
[0250] - 0 dB, when UE reports the first information (including various possible representations of the first information) and the target power class indicated by the ntn-hpue-tx-fallback indicated by the network is the same as the power class reported by the first information, or when the UE reports the first information (including various possible representations of the first information) and the network does not indicate ntn-hpue-tx-fallback, or other situations.
[0251] In addition, as described in the method, when the above multiple methods are applied, the variable P-MPRc in the transmit power configuration formula in this example should be set to 0. That is, when applying this solution, no other power reduction should be applied to cope with regulatory requirements for electromagnetic radiation.
[0252] After the transmit power configuration of the UE is determined through the method described in this method, the maximum output power PCMAX, f, c configured in the above formula will be reported to the network through methods agreed in other specifications, and the subsequent process will not be described here.
