Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0109] Currently, mid- and low-frequency spectrum resources are already extremely crowded. To meet the demand for ever-increasing data rates, exploration of higher-frequency spectrum resources, such as millimeter wave and terahertz bands, has begun. High-frequency transmission is subject to greater transmission attenuation, especially due to severe absorption by water molecules and oxygen in the air. Therefore, the transmission distance and coverage of high-frequency transmission are very limited.

[0110] On the one hand, higher frequencies mean shorter wavelengths. Compared to medium and low-frequency spectrum, more antennas can be deployed with the same aperture size, such as large-scale antennas or very large-scale antennas. On the other hand, large-scale antennas can have greater beamforming gain, which can effectively compensate for severe transmission losses, thereby expanding coverage and transmission distance. Therefore, high-frequency transmission and large-scale antenna technology are a pair of complementary technologies. As a combination of the two, high-frequency massive multiple input multiple output (MIMO) technology has good prospects. It is worth noting that high-frequency massive MIMO will lead to the hardening of wireless channels, which are mainly based on line-of-sight (LoS) propagation.

[0111] For a given antenna array (its antenna aperture is denoted as D), its electromagnetic (EM) field can be divided into near field and far field, as shown in Figure 1B. It is called the Rayleigh distance.

[0112] Obviously, the near-field range depends on the antenna aperture D and the wavelength λ. In existing cellular wireless communication systems, user equipment (UE) is mostly located in the far field of the base station's transmit antenna array. As mentioned above, as the carrier frequency increases and / or the antenna array becomes larger, the near-field range will expand. Even if the existing network topology remains unchanged, such as the distance between base stations and the distribution of UEs, current far-field UEs are likely to become near-field UEs.

[0113] Referring to Figure 1C , in the far field, the electromagnetic wave received by the UE is a plane wave, and the beam targeting the UE is a two-dimensional (2D) directional beam directed toward the target UE. Furthermore, the transmission distances from each antenna port of the base station to the UE are similar, so the average received power of the signals received by the UE from each antenna port of the base station is comparable. Therefore, the Type 1 codebook consists of a DFT vector and its oversampled version. Furthermore, each codeword (precoding vector) in the codebook is constant modulus, meaning that each element of each precoding vector (corresponding to the weight coefficient of each antenna port) has the same amplitude, differing only in phase.

[0114] If the UE is in the near field, the electromagnetic waves it receives are spherical waves, and the beam targeting the UE is a three-dimensional (3D) beam that surrounds the target UE. Furthermore, the transmission distances from each base station's antenna ports to the UE vary significantly, and the average received power of the signals received by the UE from each base station antenna port also varies significantly. Furthermore, due to the sensitivity limitations of the automatic gain control (AGC), the UE may only receive signals from some of the base station's antenna ports.

[0115] As shown in Figure 1D, assume the base station has a 16-port Very Large Scale MIMO array. UE1 measures the average received power corresponding to ports 9-11 to be significantly weaker than that corresponding to ports 0, 1, 5, and 6. Furthermore, due to obstruction by obstacles such as trees, UE1 cannot detect ports 2-4. Similarly, UE2 can only measure six ports, namely ports 10-15. Furthermore, UE2 measures the average received power corresponding to port 15 to be stronger than that corresponding to port 10. Therefore, the average received power of signals received by near-field UEs from different base station antenna ports fluctuates significantly. For near-field UEs, the performance of constant modulus precoding vectors is far inferior to that in the far field, necessitating the design of non-constant modulus codebooks. Current CSI feedback (such as Rank Indicator (RI), Channel Quality Indicator (CQI), and Precoding Matrix Indicator (PMI) feedback based on the Type 1 codebook) does not provide the base station with information related to the power differences between different antenna ports.

[0116] An embodiment of the present disclosure provides a communication method, in which a terminal measures a signal sent by a network device and reports a port power pattern to a network device.

[0117] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0118] Step S2101: The network device sends third information to the terminal.

[0119] In some embodiments, a terminal receives third information, for example, third information sent by a network device. The third information is used to configure multiple port power patterns for the terminal. Each port power pattern represents a relative relationship between the receive powers corresponding to multiple antenna ports. The antenna ports may be, but are not limited to, configured CSI-RS ports. The receive power may be, but are not limited to, average receive power.

[0120] In the above embodiment, multiple port power patterns may be configured for the terminal through the third information, so that the terminal reports the first port power pattern to the network device after measuring the signal sent by the network device.

[0121] In the embodiment of the present disclosure, the name of the third information is not limited, and may be, for example, “configuration information”, “port power pattern configuration”, etc.

[0122] In some embodiments, as shown in Table 1, the third information is used to configure the following three port power patterns:

[0124] It should be noted that Table 1 above is an example of the port power pattern and does not limit the number and expression forms of the port power patterns. For example, in actual situations, the port power pattern may also be in other expression forms.

[0125] In some embodiments, the network device may configure the multiple port power patterns for the terminal via radio resource control (RRC) signaling. The third information may be carried in the RRC signaling.

[0126] In some embodiments, step S2101 is an optional step. For example, the third information may be predefined (such as predefined in a protocol) or the third information may be sent by another subject.

[0127] Step S2102: The network device sends fourth information to the terminal.

[0128] In some embodiments, the terminal receives the fourth information, for example, the terminal receives the fourth information sent by the network device. The fourth information is used to activate or deactivate some or all of the multiple port power patterns.

[0129] In the above embodiment, among the predefined or configured multiple port power patterns, the network device can activate some port power patterns, and other inactivated port power patterns are not effective. The network device can activate / deactivate the port power pattern through media access control element (MACCE) signaling. The fourth information can be carried in the MACCE signaling.

[0130] In the embodiment of the present disclosure, the name of the fourth information is not limited, for example, it can be "activation information" or the like.

[0131] In some embodiments, step S2102 is an optional step. For example, activation / deactivation of the port power pattern may not be required or the fourth information may be sent by other entities.

[0132] Step S2103: The network device sends second information to the terminal.

[0133] In some embodiments, the terminal receives the second information, for example, the terminal receives the second information sent by the network device. The second information is used to configure whether the terminal reports the first port power pattern to the network device. Optionally, the network device can complete the above configuration through at least one of downlink control information (DCI), MAC CE, and RRC signaling. Optionally, the second information is carried in at least one of the DCI, MAC CE, and RRC signaling.

[0134] In the embodiment of the present disclosure, the name of the second information is not limited, and may be, for example, “configuration information”, “port power pattern report configuration”, etc.

[0135] In some embodiments, the second information includes configuration information of at least one CSI-RS resource or at least one CSI-RS port group, and the first port power pattern is a port power pattern corresponding to the CSI-RS resource or the CSI-RS port group. One first port power pattern corresponds to one CSI-RS resource or one CSI-RS port group.

[0136] In the above embodiment, through the above configuration information, the terminal can specifically report the port power pattern corresponding to a specific CSI-RS resource or CSI-RS port group to the network device.

[0137] In some embodiments, the second information may not include the above configuration information. For example, the terminal may report the port power pattern corresponding to each CSI-RS resource or CSI-RS port group to the network device.

[0138] Optionally, for a network device with a one-dimensional antenna array, the above configuration information can configure one CSI-RS resource (or CSI-RS port group) for the terminal, corresponding to a row of ports of the one-dimensional antenna array, but is not limited to this. For example, the above configuration information can also configure two or more CSI-RS resources (or CSI-RS port groups) for the terminal.

[0139] Optionally, for a network device with a two-dimensional antenna array, the above configuration information can configure two CSI-RS resources (or CSI-RS port groups) for the terminal, corresponding to a row of ports in the horizontal direction and a column of ports in the vertical direction of the two-dimensional antenna array, respectively, but not limited to this. For example, the above configuration information can also configure three or more CSI-RS resources (or CSI-RS port groups) for the terminal. For example, assuming that two CSI-RS resources (or CSI-RS port groups) correspond to a row of ports in the horizontal direction of the two-dimensional antenna array, and one CSI-RS resource (or CSI-RS port group) corresponds to a column of ports in the vertical direction of the two-dimensional antenna array, a total of three CSI-RS resources (or CSI-RS port groups) are configured.

[0140] In some embodiments, the second information is included in configuration information corresponding to the CSI. For example, the second information is included in a CSI report setting. Optionally, the network device sends a CSI report setting to the terminal, where the CSI report setting includes the second information.

[0141] In the above embodiment, the second information may be combined with the CSI reporting process, for example, requiring the terminal to report the first port power pattern in the CSI reporting configuration.

[0142] In some embodiments, the second information is not included in the CSI report setting.

[0143] In some embodiments, a CSI quantity in a CSI report setting includes a port power pattern.

[0144] In some embodiments, step S2103 is an optional step, that is, the network device may not send the above-mentioned second information.

[0145] Optionally, if the terminal does not receive the second information, the terminal may not report the first port power pattern to the network device, or the terminal determines whether to report the first port power pattern to the network device according to a default value.

[0146] Optionally, if the terminal receives the second information, and the second information is used to configure the terminal to report the first port power pattern to the network device, the terminal reports the first port power pattern to the network device.

[0147] Optionally, if the terminal receives the second information, and the second information is used to configure the terminal not to report the first port power pattern to the network device, the terminal does not report the first port power pattern to the network device.

[0148] Step S2104: The terminal sends first information to the network device.

[0149] In some embodiments, the first information is used to indicate a first port power pattern, and the terminal sends the first information to the network device, thereby reporting the first port power pattern to the network device. Optionally, the first information includes the first port power pattern, or the first information includes an index or number of the first port power pattern. The number of first port power patterns can be one or more, and a first port power pattern represents the relative relationship between the received powers (such as average received powers) corresponding to multiple CSI-RS ports of a CSI-RS resource (or CSI-RS port group).

[0150] In some embodiments, the terminal determines at least one port power pattern, ie, at least one first port power pattern, from a plurality of predefined or configured port power patterns.

[0151] In some embodiments, the terminal measures the signal sent by the network device to obtain the received power corresponding to multiple antenna ports (such as the average received power), and based on the relative relationship between the received powers corresponding to the multiple antenna ports, determines the first port power pattern from the multiple port power patterns and reports it to the network device.

[0152] In some embodiments, the terminal measures the signal of each CSI-RS resource or CSI-RS port group according to each CSI-RS resource or CSI-RS port group included in the second information, obtains the received power (such as the average received power) corresponding to the multiple CSI-RS ports of each CSI-RS resource or CSI-RS port group, and determines a first port power pattern corresponding to each CSI-RS resource or CSI-RS port group from the multiple port power patterns based on the relative relationship between the received powers corresponding to the multiple CSI-RS ports of each CSI-RS resource or CSI-RS port group and reports it to the network device. As an implementation method, the network device sends a multi-port CSI-RS on a CSI-RS resource, and the terminal measures the multi-port CSI-RS on the CSI-RS resource to determine the average received power corresponding to the multiple CSI-RS ports of the CSI-RS resource. Based on the relative relationship between the average received powers corresponding to the multiple CSI-RS ports, such as a monotonically increasing, monotonically decreasing, or first increasing and then decreasing relationship, a first port power pattern is determined.

[0153] In some embodiments, the first port power pattern may be reported to the network device as a CSI quantity, and the first information may be included in the CSI. Optionally, the terminal sends CSI to the network device, where the CSI includes the first information. Optionally, the CSI includes an index or number of the first port power pattern.

[0154] In the above embodiment, the first information and the CSI reporting process may be combined, that is, the terminal reports the first port power pattern when reporting the CSI.

[0155] In some embodiments, the first port power pattern may be reported to the network device via a physical uplink control channel (PUCCH) and / or a physical uplink shared channel (PUSCH), and the first information may be carried in the PUCCH and / or PUSCH.

[0156] For ease of understanding, the communication method proposed in the embodiment of the present disclosure is exemplarily described below in conjunction with a specific embodiment.

[0157] Referring to Figure 1E , the base station is equipped with a very large antenna array, virtualized as 16 one-dimensional antenna ports. The base station configures three port power patterns for UE1, UE2, and UE3 via RRC signaling, as shown in Table 1 above. The base station transmits CSI-RS for 16 ports on a single CSI-RS resource and notifies UE1, UE2, and UE3 of the corresponding configuration via RRC signaling. The CSI reporting configuration sent by the base station to UE1, UE2, and UE3 requires them to report the port power pattern.

[0158] Based on the measurement of the CSI-RS of the configured 16 ports, UE1 determines and reports that its port power pattern is pattern 2 (monotonically decreasing), indicating that the average received power corresponding to ports 0 to 15 is monotonically decreasing; based on the measurement of the CSI-RS of the configured 16 ports, UE2 determines and reports that its port power pattern is pattern 3 (first increasing and then decreasing), indicating that the average received power corresponding to ports 0 to 15 first increases and then decreases; based on the measurement of the CSI-RS of the configured 16 ports, UE3 determines and reports that its port power pattern is pattern 1 (monotonically increasing), indicating that the average received power corresponding to ports 0 to 15 is monotonically increasing.

[0159] In the above embodiment, the terminal reports the first port power pattern to the network device, which can provide a reference and basis for the network device to use a non-constant modulus precoding vector and power control.

[0160] As an implementation method, referring to Figure 1E, the base station can determine the approximate position of the UE based on the port power pattern reported by the UE. For example, based on the port power pattern reported by UE1 (monotonically decreasing), it can be determined that UE1 is approximately at the left position of the transmitting antenna array, and based on the port power pattern reported by UE2 (first increasing and then decreasing), it can be determined that UE2 is approximately at the middle position of the transmitting antenna array. Based on the port power pattern reported by UE3 (monotonically increasing), it can be determined that UE3 is approximately at the right position of the transmitting antenna array. Knowing this information is beneficial for the base station to perform power control between ports for each UE (such as power compensation), or when the average received power corresponding to each port is significantly different, some ports can be selected for transmission with the UE.

[0262] One port power pattern corresponds to one CSI-RS resource or CSI-RS port group. The above-mentioned port power pattern reporting configuration includes at least one CSI-RS resource or CSI-RS port group, that is, it indicates that the UE needs to report the port power pattern corresponding to the CSI-RS resource or the CSI-RS port group.

[0263] The UE measures the signal of each CSI-RS resource or CSI-RS port group according to each CSI-RS resource or CSI-RS port group included in the port power pattern reporting configuration, obtains the received power corresponding to multiple CSI-RS ports of each CSI-RS resource or CSI-RS port group, and thus determines the port power pattern corresponding to each CSI-RS resource or CSI-RS port group.

[0264] Step S5104: The UE reports the at least one port power pattern to the base station.

[0265] In some embodiments, the port power pattern may be reported to the base station as a CSI quantity.

[0266] In some embodiments, the port power pattern may be reported via PUCCH and / or PUSCH.
