[0136] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or part of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationship between the entities is illustrative only.

[0137] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0138] In some embodiments, for a communication system with an antenna array (whose antenna aperture is D), its electromagnetic (EM) field can be divided into a near field and a far field. For example, FIG1b is a schematic diagram of the electromagnetic field division according to an embodiment of the present disclosure. As shown in FIG1b, near the electromagnetic field source, the range within several times the wavelength of the source is called the near field. Within this range, the propagation of the electromagnetic field is mainly affected by the direct effect of charge and current. The electromagnetic field in the near field gradually weakens with increasing distance and presents a complex electromagnetic field distribution; far away from the field source, the range of several times or dozens of times the wavelength of the source is called the far field. Within the far field range, the propagation of the electromagnetic field is mainly a radiation field. The electromagnetic field in the far field is characterized by obvious volatility and follows the propagation law of radiation waves. For example, in this embodiment, the boundary between the near field and the far field under the same electromagnetic field source is the Rayleigh distance Where D is the antenna aperture of the antenna array corresponding to the electromagnetic field source, and λ is the wavelength of the electromagnetic field source.
[0139] In some embodiments, the time and phase of the far-field UE (User Equipment) and the near-field UE receiving the electromagnetic field antenna array are different. For example, FIG1c is a schematic diagram of the near-field UE and the far-field UE receiving electromagnetic waves according to an embodiment of the present disclosure. In the electromagnetic waves transmitted by the electromagnetic field source, the range of the near field depends on the antenna aperture (D) and the wavelength (λ). The distance from the electromagnetic field source to Ruili is The range is the near field, and the farthest distance that the electromagnetic field source can propagate from the Ruili distance is the far field. In this embodiment, the electromagnetic field source is an electromagnetic field source with multipath propagation. For the UE in the far field, the electromagnetic waves reaching the UE from its different antenna ports or arrays are plane waves. The beam for the UE is a two-dimensional (2dimension, 2D) directional beam pointing to the target UE. For any path in the multipath propagation MIMO, the time and phase of the waves reaching the UE receiving antenna array are equally spaced, as shown in (a) in Figure 1c. For the UE in the near field, the electromagnetic wave received by the UE is a spherical wave, and the beam for the UE is a three-dimensional (3dimension, 3D) beam that surrounds the UE. For any path in the multipath propagation, the time and phase of the waves reaching the UE receiving antenna array are no longer equally spaced, as shown in (b) in Figure 1c. When the UE is in the near field, for any path in the multipath propagation, the time and phase of the waves reaching the UE receiving antenna array are no longer equally spaced, resulting in differences in the transmission power required for different paths in the near-field UE.
[0140] In some embodiments, in the 5G NR corresponding to type I codebook, since only far-field UEs are considered, the distances from different ports to the UE can be approximately the same. Using DFT (Discrete Fourier Transformation) beamforming, the transmit power of different ports is the same. However, for near-field UEs, the distances from different ports to the UE will vary significantly, so the power from different ports to the terminal will also vary significantly. If the network device still transmits power based on the same amplitude for each port, then ports with better channels will not be better utilized, while power transmission on ports with poor channels will result in a certain amount of power waste. For example, this embodiment proposes port-based power information reporting. The power information can be the absolute value and / or relative value of the Layer 1 Reference Signal Received Power (L1-RSRP) of each port or port group reported by the terminal, or the amplitude coefficient of each port reported by the terminal. This allows the network device to determine the channel status between different ports and the terminal based on the power reporting information, and allocate power based on the channel status, thereby improving the transmission performance of near-field terminals.
[0141] Figure 2 is an interactive diagram of a power information reporting method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiment of the present disclosure relates to a power information reporting method, which is executed by a terminal and a network device. The method includes:
[0142] Step S2101: The network device sends first configuration information.
[0143] In some embodiments, the first configuration information includes reference signal resource configuration information. For example, the reference signal resource configuration information is used to configure the relevant parameters and allocation methods of the reference signal in the wireless communication system, where the reference signal is an important signal used by the UE to receive and demodulate the signal. The reference signal resource configuration information includes the frequency resource configuration, time domain configuration, antenna port configuration, and corresponding mapping relationship of the reference signal. Through the reference signal resource configuration information, the allocation and scheduling of the reference signal can be achieved to ensure the normal operation of the wireless network and improve communication efficiency and performance. In a wireless communication system, the reference signal resource configuration information is usually sent by the base station to the UE through signaling, and can be dynamically adjusted according to different wireless resource configuration methods to meet different communication needs and network optimization.
[0144] In some embodiments, the name of the reference signal resource configuration information is not limited, and may be, for example, "configuration information", "resource indication information", "reference signal indication information", etc.
[0145] In some embodiments, the reference signal resource configured by the reference signal resource configuration information corresponds to multiple ports or multiple port groups. For example, the wireless communication system in this embodiment is a multi-path multi-transmission communication system, and the reference signal resources in the communication system can correspond to multiple antenna ports or multiple antenna port groups, and one or more reference signal resources can be mapped to multiple antenna ports or antenna port groups to support multi-antenna transmission and multiple-input multiple-output (MIMO) technology. When configuring the reference signal resource configuration information, it is necessary to specify the information of the antenna port or antenna port group to which the reference signal resource is mapped, including the number of antenna ports, polarization mode, resource allocation mode, etc. This helps the system implement spatial multiplexing, beamforming and other technologies in wireless communications, and improves the transmission efficiency and coverage of the signal. By configuring the reference signal resources to correspond to multiple ports or multiple port groups, the performance of the multi-antenna system can be better utilized, the capacity and coverage of the communication system can be improved, and thus the user experience and network performance can be improved.
[0146] In some embodiments, the time and phase intervals of the receiving antenna arrays corresponding to far-field UEs are equally spaced. When allocating transmit power to far-field UEs, the electromagnetic field source can evenly divide the transmit power based on the far-field UE's location. However, the distances from different ports to near-field UEs vary and are unevenly distributed. Therefore, near-field UEs need to report power information to assist network equipment in allocating transmit power. For example, in this embodiment, the UE reporting power information is a near-field UE located within the near-field range of the electromagnetic field source.
[0147] Step S2102: The terminal determines power information of at least one port among a plurality of ports, or determines power information of at least one port group among a plurality of port groups.
[0148] For example, in this embodiment, the port in the terminal refers to a virtual connection point on the antenna, which corresponds to one or more antenna elements (such as antenna subarrays, monopoles or polarizers) on the antenna. Each antenna port corresponds to a specific signal transmission path through which wireless signals can be transmitted and received. In a MIMO (multiple input multiple output) system, different antenna ports can be used to send and receive independent data streams to achieve spatial diversity and multi-antenna transmission. A port group refers to a collection of antenna ports that work together to send or receive signals to a wireless channel. In a MIMO system, a port group is often used to describe signals sent from multiple antenna ports. A port group is usually used to describe the antenna configuration used in spatial diversity and beamforming processes. More efficient use of wireless channels can be achieved by properly configuring the port group.
[0149] For example, after receiving the first configuration information sent by the network device, the terminal determines, in response to the first configuration information, power information of at least one port among multiple ports of the terminal, or power information of at least one port group among the multiple ports. The power information is used to indicate the channel status between the terminal and different ports or different port groups.
[0150] In some embodiments, the power information includes first power information.
[0151] Illustratively, the power information includes first power information, where the first power information is used to indicate the channel quality of at least one port or the channel quality of at least one port group currently corresponding to the UE.
[0152] In some embodiments, the name of the power information is not limited, and it can be, for example, power indication information, channel quality information, channel state information, received power information, etc.
[0153] In some embodiments, the first power information includes Layer 1 reference signal received power (L1-RSRP) information or Layer 1 signal-to-interference-plus-noise (SIN) ratio (L1-SINR) information. L1-RSRP information refers to the RSRP indicator of the reference signal sent by the network device received by the terminal. It is measured and reported at Layer 1 (L1) of the physical layer protocol stack. RSRP represents the power of the reference signal received by the terminal. It is used to assess the quality of the signal received by the mobile phone and helps determine whether the signal strength is sufficient for reliable communication. L1-SINR information is the physical layer (L1) signal to interference plus noise ratio (SINR). SINR is the ratio of the received signal power to the interference plus noise power and can represent the received signal quality. A higher SINR generally indicates better signal quality, while a lower SINR generally leads to degraded communication performance. L1-SINR provides more comprehensive signal quality information, including signal strength and interference level. Network devices and terminals use L1-SINR to make decisions regarding radio resource allocation, beamforming, power control, and other wireless network optimization and management. L1-SINR information is also a very important parameter in system planning, optimization, and troubleshooting. It should be noted that, in this embodiment, the signal type of the first power information is not limited, and it can be a variety of signal types used to indicate the received signal power in an antenna port or an antenna port group.
[0154] In some embodiments, the power information includes a first index and an absolute value of the first power information, wherein the first index is the index of the port corresponding to the strongest first power information or the index of the port group corresponding to the strongest first power information among the at least one first power information included in the power information, and the absolute value of the first power information is the absolute value of the strongest first power information.
[0155] For example, the power information includes a first index and a first power information absolute value. In response to the first configuration information, the terminal measures power reception conditions of multiple ports or multiple port groups corresponding to the reference signal resource, and determines one or more power values corresponding to at least one port or at least one port group. The absolute value of the strongest first power information among the multiple power values is the first power information absolute value, the port corresponding to the first power information absolute value is the first port, and the index of the first port is the first index. For example, in response to the first configuration information, the terminal measures and determines multiple power information as the L1-RSRP of at least one port or the L1-RSRP of a port group, including: L1-RSRP of port 1, -63dBm, L1-RSRP of port 2, -55dBm, L1-RSRP of port 3, -98dBm, L1-RSRP of port 4, -100dBm, L1-RSRP of port 5, -63dBm. When the power information includes a first index and a first power, the strongest first power information is determined to be the L1-RSRP corresponding to port 2. The power information includes the first index of port 2, and the absolute value of the L1-RSRP of the strongest L1-RSRP corresponding to port 2 is -55dBm.
[0156] In some embodiments, the absolute value of the first power information is quantized by a first bit.
[0157] For example, the absolute value of the first power information can be quantized using 7 bits. In a communication system, 7-bit quantization of the absolute value of the first power information can reduce the bandwidth required to transmit and process the value. 7-bit quantization can make the processing of the absolute value of the first power information simpler and more efficient. Using 7-bit quantization can also ensure data compatibility between different devices and systems. 7-bit quantization is a process of mapping a continuous range of values to a discrete, smaller range of values. In this process, the absolute value of the first power information is typically converted to a 7-bit (or 7-bit) binary number by rounding or truncation. In this representation, the maximum value is 127 (1111111) and the minimum value is 0 (0000000). In communication systems, 7-bit quantization is often used to quantize continuous analog signals into digital signals or compress large-scale data into small-scale data, thereby saving bandwidth and storage space.
[0158] In some embodiments, the power information includes a relative value of first power information, the relative value of the first power information is the relative value of the first power information between the strongest first power information and other first power information except the strongest first power information in at least one first power information included in the power information, the relative value of the first power information corresponds to a second index, and the second index includes the index of the port or the index of the port group.
[0159] For example, on the basis that the power information reported by the above-mentioned terminal includes the first index and the absolute value of the first power information, the reported power information may also include a relative value of the first power information. The relative value of the first power information is the relative value of the first power information between the other first power information except the strongest first power information in at least one first power information included in the power information and the strongest first power information. That is, in this embodiment, after reporting the absolute value of the strongest first power information and the first index of the strongest first power information, it is also necessary to report the relative value between the other first power information measured by the terminal and the strongest first power information in the power information.
[0160] It should be noted that in this embodiment, when the power information includes L1-RSRP information, the value range of the L1-RSRP information is -50dBm to -120dBm, the absolute value of the first power information is the value of the strongest first power information, and the relative value of the first power information is the difference between the first power information corresponding to other ports and the strongest first power information. For example, the L1-RSRP of the terminal corresponding to port 1 is -63dBm, the L1-RSRP of port 2 is -55dBm, the L1-RSRP of port 3 is -98dBm, and the L1-RSRP of port 4 is -100dBm; where the strongest first power information is the L1-RSRP corresponding to port 2, and the absolute value is -55dBm, then the relative value of port#1 is -63dB-(-55dBm)=-8dB. Optionally, the relative value of port#1 can also be -55dB-(-63dBm)=8dB.
[0161] Optionally, in some embodiments, the power information includes a second index.
[0162] For example, the first power information relative value corresponds to the second index, and the second index can be the index of the port or the index of the port group. In the communication system of this embodiment, no reporting rules are set. To facilitate the network device to distinguish different second ports corresponding to the first power information relative value, when reporting the first power information relative value, the second index corresponding to the first power information relative value is reported.
[0163] In some embodiments, the power information includes at least one first power information relative value, and a bit position of the first power information relative value in the power information is determined based on a second index corresponding to the first power information relative value.
[0164] For example, in this embodiment, the power information includes at least one first power information relative value. After the power information is bit-quantized using a first bit, the bit position of the first power information relative value in the power information is determined based on the second index corresponding to the first power information relative value. In the communication system, the arrangement order of the first power information relative values can be determined by a protocol in the terminal and the network device. For example, the first power information relative values corresponding to each port or port group can be arranged in descending order according to the port number or port group number or in ascending order according to the port number or port group number based on the port number or port group number.
[0165] For example, the reference signal resource corresponds to 8 ports: port#0, port#1, port#2, port#3, port#4, port#5, port#6, and port#7. The port corresponding to the strongest first power information is port#4. After the power information is quantized using the first bit information, the order of the corresponding bit information is: the first index (port#4), the absolute value of the first power information (the absolute value of the power information corresponding to port#4), the relative value of port#0, the relative value of port#1, the relative value of port#2, the relative value of port#3, the relative value of port#5, the relative value of port#6, and the relative value of port#7. The relative values of port#0-port#7 (excluding port#4) are arranged in the order of the corresponding port numbers. It should be noted that in this embodiment, the arrangement order of the relative values of the first power information corresponding to other ports in the power information can be determined by protocol settings. The network device can determine, based on the arrangement order of the relative values of port#x reported in the power information, which port's first power information and the strongest first power information are the relative values of the port#x.
[0166] In some embodiments, the power information does not include the second power information, and the second power information is the first power information that is less than or equal to the first threshold value.
[0167] For example, in response to the first configuration information, the terminal determines power information of at least one port or at least one port group, and determines the power information of each port or each port group. If the second power information corresponding to the second port is less than or equal to the first threshold value, the second power information is not included in the reported power information. After receiving the reported power information, if the network device determines that the first power information of the corresponding port does not exist in the power information, it indicates that the first power information of the port is lower than the first threshold value.
[0168] Optionally, in some embodiments, when the terminal determines that the second power information corresponding to the second port is lower than the first threshold value, the first threshold value can be used as the reported first power information corresponding to the second port, and the relative value between the first threshold value and the strongest first power information can be used as the relative value of the first power information of the second port. After quantifying the relative value of the first power information, the quantized relative threshold value can be reported.
[0169] In some embodiments, the power information includes first bit sequence information, and the first bit sequence information is used to indicate a reporting status of first power information corresponding to each index in at least one index, where the index includes a port index or a port group index.
[0170] For example, if some first power information in the terminal meets the above-mentioned first threshold value condition, and the first power information corresponding to some ports is not reported, it is necessary to include first bit sequence information in the power information to indicate the reporting status of the first power information corresponding to each port index in the power information. For example, the reporting status of the first power information at the corresponding bit is indicated by the value of each bit in the first bit sequence information, where the length of the first bit sequence information can be the total number of ports in the terminal or the total number of ports minus 1. When the bit length of the first bit sequence information is the total number of ports, the first bit represents the reporting status of the first power information of port number 1. When the value of the bit is "0", it indicates that the first power information at the port number corresponding to the bit is not reported. When the value of the bit is "1", it indicates that the first power information at the port number corresponding to the bit is reported. When the length of the first bit sequence information is the total number of ports minus 1, it indicates that the strongest first power information will definitely be reported. Therefore, the bit of the port number corresponding to the strongest first power information is omitted in the first bit sequence information.
[0171] In some embodiments, the terminal corresponds to 8 ports, port#0, port#1, port#2, port#3, port#4, port#5, port#6, and port#7. The first index corresponding to the strongest first power information is port#4, where the first power information of port#0 and port#7 is less than the first threshold value, so port#0 and port#7 are not reported. The length of the first bit sequence information is the total number of ports, and the relative value of the first power information is reported in the order of the port numbers. The order of the bit information corresponding to the power information is sequence #1: first index (port#4), the absolute value of the strongest first power information, the first bit sequence information (a bit sequence used to indicate the reporting status of the first power information of each port) 01111110 (the corresponding number of bits is the same as the total number of ports, which is 8 bits), the relative value of port#1, the relative value of port#2, the relative value of port#3, the relative value of port#5, and the relative value of port#6. For example, if the length of the first bit sequence information is the total number of ports minus 1, then based on the 8 ports corresponding to the above terminal, the bit sequence order #1 corresponding to the power information can also be: first index (port#4), the absolute value of the strongest first power information, the first bit sequence information (a bit sequence used to indicate the first power information reporting status of each port) 0111110 (the corresponding number of bits is the total number of ports minus 1, which is 7 bits), port#1 relative value, port#2 relative value, port#3 relative value, port#5 relative value, port#6 relative value. Among them, the bit corresponding to port#4 in the first bit sequence information is omitted.
[0172] Optionally, in some embodiments, the order of the bit information corresponding to the power information can also be sequence #2: first bit sequence information (a bit sequence used to indicate the first power information reporting status of each port) 01111110 (the corresponding number of bits is the same as the total number of ports, which is 8 bits), first index (port#4), absolute value of the strongest first power information, relative value of port#2, relative value of port#3, relative value of port#5, and relative value of port#6. Optionally, if the length of the first bit sequence information is the total number of ports minus 1, the bit corresponding to port#4 in the first bit sequence information can also be omitted. The first bit sequence information in sequence #2 can refer to the first bit sequence information in sequence #1 above and will not be repeated here.
[0173] The difference between sequence #2 and sequence #1 is that the first bit sequence information of sequence #2 comes first, so this bit sequence needs to include the bits of the first index. The number of bits indicating the first index can be selected from only one of the port indexes that will be reported, so the number of bits may be smaller. For example, if sequence #2 indicates that only four ports will report, then the first index only requires 2 bits, that is, one can be selected from the four. Sequence #1, on the other hand, has the first index first, so it requires 3 bits, and one can be selected from the eight. Later, when reporting which ports' corresponding power information will be reported, one less bit can be used.
[0174] In some embodiments, the power information includes an amplitude coefficient.
[0175] For example, the amplitude coefficient generally refers to a coefficient used to represent the amplitude gain or attenuation of a signal or system in signal processing or system analysis. The amplitude coefficient can refer to some common parameters, such as gain, attenuation or amplification factor, or amplitude coefficient. It can be used to describe the transfer function, the gain of the system, or the amplitude change of the signal after processing. In a communication system, the amplitude coefficient is often used to represent the strength of the signal. For example, the modulation depth in amplitude modulation is the amplitude coefficient that describes the change in carrier amplitude. In filter design, the amplitude coefficient also reflects the gain or attenuation of the filter at different frequencies. The terminal responds to the first configuration information, determines the amplitude coefficient of the reference signal resource corresponding to at least one port or at least one port group, and then reports the amplitude coefficient through power information. That is, the terminal reports the proportional value of the power corresponding to at least one port or at least one port group.
[0176] In some embodiments, the power information includes a first index, which is an index corresponding to a port or a port group having a largest amplitude coefficient.
[0177] For example, the amplitude coefficient corresponds to the strongest first power information, and the port with the largest amplitude coefficient in at least one port or at least one port group corresponding to the reference signal resource is the same as the port corresponding to the strongest first power information.
[0178] For example, the power information includes the first index corresponding to the port with the maximum amplitude coefficient. The maximum amplitude coefficient is preset to 1 by the protocol, and the amplitude coefficients corresponding to other ports in the terminal are all less than 1. In this case, the number of bits required to report the first index is related to the total number of ports. For example, when the total number of ports is 8, the number of bits required to report the first index is 3.
[0179] In some embodiments, the amplitude coefficient includes a second amplitude coefficient, the second amplitude coefficient corresponds to a second index, the second index is an index other than the first index in the plurality of indexes, and the second index includes an index of a port or an index of a port group.
[0180] For example, the power information includes the first index corresponding to the strongest amplitude coefficient, as well as the second amplitude coefficients corresponding to other ports, and the second index corresponding to the second amplitude coefficient. Similar to the logic for reporting the relative value of the first power information described above, in this embodiment, in order for the network device to determine the channel state information between other ports in the terminal and the terminal, it is necessary to report the second amplitude coefficients of the other ports. In order to distinguish the second amplitude coefficients of each port, it is necessary to report the second index of the port corresponding to the second amplitude coefficient.
[0181] For example, in some embodiments, the power information includes a first index corresponding to the strongest amplitude coefficient. When the amplitude coefficient is reported, the amplitude coefficient includes a second amplitude coefficient, where the second amplitude coefficient is a relative value relative to the strongest amplitude coefficient of 1, where the relative value is a positive number less than 1. For example, a terminal corresponds to 8 ports, port#0, port#1, port#2, port#3, port#4, port#5, port#6, and port#7, where the first index corresponding to the strongest amplitude coefficient is port#4. The reported power information is: port#4, relative value of the amplitude coefficient of port#0, relative value of the amplitude coefficient of port#1, relative value of the amplitude coefficient of port#2, relative value of the amplitude coefficient of port#3, relative value of the amplitude coefficient of port#5, relative value of the amplitude coefficient of port#6, and relative value of the amplitude coefficient of port#7. When reporting the second amplitude coefficient, the corresponding relative values of the amplitude coefficients can be reported sequentially according to the order of the second indexes.
[0182] Optionally, in some embodiments, the power information also includes a second index of the port corresponding to the second amplitude coefficient, that is, in addition to the first index corresponding to the strongest coefficient in the reported power information, the second amplitude coefficient also includes a second index corresponding to at least one other port or at least one port group, wherein the second index is the index of at least one port, or the index of at least one port group.
[0183] Optionally, only the second amplitude coefficients corresponding to other ports may be reported in the power information without reporting the second indexes corresponding to the second amplitude coefficients. The second amplitude coefficients are reported in the order of the port numbers.
[0184] In some embodiments, the bit position of the second amplitude coefficient in the power information is determined based on a second index corresponding to the second amplitude coefficient.
[0185] For example, in this embodiment, the second amplitude coefficient corresponding to the second index can be quantized by setting a protocol. For example, the second amplitude coefficient can be quantized as follows: 0. Different bit values correspond to different second amplitude coefficients. The bit position of the second amplitude coefficient in the power information is determined according to the second index corresponding to the second amplitude coefficient.
[0186] In some embodiments, the power information does not include a third amplitude coefficient, and the third amplitude coefficient is an amplitude coefficient that is less than or equal to a second threshold value.
[0187] For example, a second threshold is set for the amplitude coefficient. After determining the second amplitude coefficient for at least one port or at least one port group, the terminal compares the second amplitude coefficient with the second threshold. If a third amplitude coefficient among the second amplitude coefficients is determined to be less than the second threshold, the third amplitude coefficient is not reported in the power information.
[0188] Optionally, if the second amplitude coefficient determined by the terminal includes a third amplitude coefficient, the second threshold value may be bit-quantized, and the bit-quantized value may be used as the quantized value of the third amplitude coefficient, and the quantized value may be reported through power information.
[0189] In some embodiments, the power information includes second bit sequence information, and the second bit sequence information is used to indicate the reporting status of the amplitude coefficient corresponding to each index in at least one index, where the index includes the index of the port or the index of the port group.
[0190] For example, if there is a third amplitude coefficient that is not reported, the power information includes a second bit sequence information, and the second bit sequence information is used to indicate the reporting status of the amplitude coefficient corresponding to each index in at least one index. Similar to the above-mentioned first bit sequence information, the second bit sequence information is used to indicate which ports' amplitude coefficients are reported and which ports' amplitude coefficients are not reported in the power information. Similarly, "0" can be used to indicate that the amplitude coefficient of the corresponding port is not reported, and "1" can be used to indicate that the amplitude coefficient of the corresponding port is reported.
[0191] In some embodiments, if all second amplitude coefficients in the power information need to be reported, the power information includes the first index corresponding to the maximum amplitude coefficient and the second amplitude coefficients of other ports. The corresponding power information reporting order is #0: first index, second amplitude coefficient. If the power information contains a third amplitude coefficient that does not need to be reported, the power information includes the first index corresponding to the maximum amplitude coefficient, the second amplitude coefficients of other ports, and second bit sequence information. After the power information is bit-quantized, the corresponding bit information order is #1: first index, second bit sequence information, and second amplitude coefficient. When the second amplitude coefficient includes multiple amplitude coefficients, the second amplitude coefficients are reported in the order of the corresponding port numbers. For example, among port#0, port#1, port#2, port#3, port#4, port#5, port#6, and port#7, the first index is port#4, and port#0 and port#7 are not reported. Then, the bit information sequence #1 is: port#4, 01111110 (the corresponding number of bits is the same as the total number of ports, which is 8 bits), port#1 amplitude coefficient, port#2 amplitude coefficient, port#3 amplitude coefficient, port#5 amplitude coefficient, and port#6 amplitude coefficient. Optionally, if the length of the second bit sequence information is the total number of ports minus 1, then based on the 8 ports corresponding to the above-mentioned terminal, the bit sequence sequence #1 corresponding to the power information can also be: port#4, 0111110 (the corresponding number of bits is the total number of ports minus 1, which is 7 bits), port#1 amplitude coefficient, port#2 amplitude coefficient, port#3 amplitude coefficient, port#5 amplitude coefficient, and port#6 amplitude coefficient, where the bit corresponding to port#4 is omitted in the first bit sequence information.
[0192] Optionally, if there is a third amplitude coefficient in the power information that does not need to be reported, the power information includes the first index corresponding to the maximum amplitude coefficient, the second amplitude coefficients of other ports, and the second bit sequence information. After the power information is bit-quantized, the order of the corresponding bit information can also be #2: 01111110 (the corresponding number of bits is the same as the total number of ports, which is 8 bits), the first index, port#1 amplitude coefficient, port#2 amplitude coefficient, port#3 amplitude coefficient, port#5 amplitude coefficient, port#6 amplitude coefficient. The setting difference and setting reasons of the above sequence #1 and sequence #2 are the same as the setting difference and setting reasons of the above sequence #1 and sequence #2 in the first bit sequence. You can refer to the above first bit sequence and will not repeat them here.

[0196] In some embodiments, power information is included in the beam report.
[0197] Step S2103: Send power information to the network device.
[0198] For example, the terminal sends power information to the network device, and by reporting the power information corresponding to each port, the terminal provides the base station with channel status information between different ports or different port groups and the terminal, so that the base station can better allocate power to different ports or different port groups based on the channel status information to improve the transmission performance of the near-field terminal.

[0269] FIG5 is a flow chart of a method for reporting power information according to an embodiment of the present disclosure. As shown in FIG5 , the embodiment of the present disclosure relates to a method for reporting power information, which is executed by a terminal. The method includes:
[0270] Step S5101: Receive first configuration information.
[0271] In some embodiments, the first configuration information includes reference signal resource configuration information, wherein the reference signal resources configured in the reference signal resource configuration information correspond to multiple ports or multiple port groups.
[0272] Step S5102: Obtain power information corresponding to at least one port in a plurality of ports or a plurality of port groups corresponding to a reference signal resource, or power information corresponding to at least one port group.
[0273] For example, after receiving the first configuration information, the terminal determines, based on the first configuration information, multiple ports or multiple port groups corresponding to the reference signal resources configured by the reference signal resource configuration information, and obtains power information of at least one port among the multiple ports, or obtains power information of at least one port group among the multiple port groups.
[0274] In some embodiments, the power information includes first power information, and the first power information includes L1-RSRP information or L1-SINR information.
[0275] In some embodiments, the power information reported by the terminal includes the first index of the port corresponding to the strongest first power information and the absolute value of the strongest first power information. For example, the absolute value of L1-RSRP or the absolute value of L1-SINR can be quantized using 7 bits.
[0276] In some embodiments, the reported power information includes relative values of L1-RSRP corresponding to other ports and the strongest L1-RSRP.
[0277] For example, the L1-RSRP relative value is quantized using 7 bits. Other port indexes do not need to be reported. Simply arrange the L1-RSRP bit positions in ascending order of port index. For example, if a terminal has 8 ports: port#0, port#1, port#2, port#3, port#4, port#5, port#6, and port#7, and the strongest port is port#4, the bit information order can be: strongest port index (#4), strongest L1-RSRP absolute value, port#0 relative value, port#1 relative value, port#2 relative value, port#3 relative value, port#5 relative value, port#6 relative value, and port#7 relative value. Port#x values with higher values at the beginning represent lower bits.
[0278] In some embodiments, L1-RSRP below a first threshold may not be reported, or may be quantized to the threshold value.
[0279] For example, if the L1-RSRP corresponding to some port indices is not reported, a bit is required to indicate which port indices are reported and which are not. The length of this bit sequence can be the total number of ports or the total number of ports minus 1. When the bit sequence length is the total number of ports, that is, each port corresponds to one bit, a "1" indicates that the corresponding L1-RSRP is reported, and a "0" indicates that the corresponding L1-RSRP is not reported. When the bit sequence length is the total number of ports minus 1, the port index corresponding to the strongest L1-RSRP is reported, so this bit can be omitted. For example, there are 8 ports in total: port#0, port#1, port#2, port#3, port#4, port#5, port#6, and port#7. The strongest port is port#4. Port#0 and port#7 are not reported. Then, bit information sequence #1 is: strongest port index (#4), strongest L1-RSRP absolute value, bit sequence indicating which port indexes are reported, relative value of port#1, relative value of port#2, relative value of port#3, relative value of port#5, and relative value of port#6. A higher relative value of port#x corresponds to a lower port index.
[0280] Optionally, the bit information order #2 can be as follows: indicating which port indexes are reported, the strongest port index (#4), the strongest L1-RSRP absolute value, the relative value of port#1, the relative value of port#2, the relative value of port#3, the relative value of port#5, and the relative value of port#6.
[0281] It should be noted that the difference between sequence #2 and sequence #1 is that in sequence #2, the bit sequence indicating which port indexes are reported comes first, so this bit sequence must include the strongest port index. However, the number of bits used to indicate the strongest port index can be reduced, as only one of the reported port indexes can be selected. For example, if sequence #2 indicates that only four port indexes are reported, only two bits are needed for the strongest port index, and one can be selected from the four. Sequence #1, on the other hand, places the strongest port index first, so three bits are needed to select one from the eight. This reduces the number of bits needed to indicate which port indexes are reported.
[0282] In some embodiments, power information includes amplitude coefficients. That is, instead of reporting absolute values, the base station only needs to be informed of the power ratios corresponding to each port index. For example, the port index corresponding to the port with the maximum amplitude coefficient of 1 is reported. The number of bits required for the port index depends on the total number of ports (8 ports, corresponding to 8 bits). The amplitude coefficients corresponding to other ports are all less than 1.
[0283] In some embodiments, the amplitude coefficients corresponding to other ports are quantized to what values can be set through the protocol. For example, the second amplitude coefficient can be quantized to: 0. Different bit values correspond to different second amplitude coefficients. The bit position of the second amplitude coefficient in the power information is determined according to the second index corresponding to the second amplitude coefficient.
[0284] In some embodiments, if there are amplitude coefficients that are not reported, a bit sequence may be reported first to indicate which ports' amplitude coefficients will be reported and which ports' amplitude coefficients will not be reported. The difference between the reporting order and the previous L1-RSRP information is that there is no L1-RSRP absolute value item. For example, the terminal corresponds to 8 ports, port#0, port#1, port#2, port#3, port#4, port#5, port#6, port#7, and the strongest port is port#4. (1) If all are reported, the reporting order is: the strongest port index (#4), port#0 amplitude coefficient, port#1 amplitude coefficient, port#2 amplitude coefficient, port#3 amplitude coefficient, port#5 amplitude coefficient, port#6 amplitude coefficient, port#7 amplitude coefficient. (2) If some amplitude coefficients can be left unreported, for example, if the amplitude coefficients of port#0 and port#7 are lower than the second threshold, then the amplitude coefficients of port#0 and port#7 are not reported. In this case, the bit information order #1 can be as follows: the strongest port index (#4), the bit sequence indicating which port indexes are reported, the amplitude coefficient of port#1, the amplitude coefficient of port#2, the amplitude coefficient of port#3, the amplitude coefficient of port#5, and the amplitude coefficient of port#6. Alternatively, the bit information order #2 can also be as follows: the bit sequence indicating which port indexes are reported, the strongest port index (#4), the amplitude coefficient of port#1, the amplitude coefficient of port#2, the amplitude coefficient of port#3, the amplitude coefficient of port#5, and the amplitude coefficient of port#6.
[0285] In some embodiments, the power information is included in the PMI information of the CSI report.
[0286] In some embodiments, the power information is included in the PMI information of the type I and / or type II codebook.
[0287] In some embodiments, the report corresponding to the power information is independent of the PMI report.
[0288] In some embodiments, power information is included in the beam report.
[0289] Step S5103: Send power information to the network device.
[0290] For example, after determining the power information, the terminal sends the power information to the network device. The network device can determine the channel status between different ports and the terminal based on the power information, and can reasonably allocate power between different ports based on the channel status, fully utilizing the communication channel and improving the transmission performance of the near-field terminal.
[0291] In the above solution, the terminal reports the power information corresponding to each port, providing the base station with channel state information between different ports and the terminal, so that the base station can better allocate power at different ports to improve the transmission performance of the near-field terminal.
[0292] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.
[0293] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.
[0294] In the embodiments of the present disclosure, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable.
