In some cases, they may also be understood as "equipment", "device", "circuit", "network element", "node", "function", "unit", "section", "system", "network", "chip", "chip system", "entity", "body", etc.

[0105] In some embodiments, "network" can be interpreted as devices included in the network, such as access network devices, core network devices, etc.

[0106] In some embodiments, "access network device (AN device)" may also be referred to as "radio access network device (RAN device)," "base station (BS)," "radio base station," or "fixed station."

[0108] In some embodiments, the acquisition of data, information, etc., may comply with the laws and regulations of the country where the location is situated.

[0109] In some embodiments, data, information, etc., may be obtained with the user's consent.

[0110] Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.

[0111] In communication scenarios, high-frequency bands and massive MIMO (Massively Multi-Sized Antenna Arrays) are introduced to improve spectral efficiency. Massive MIMO can provide greater beamforming gain, effectively compensating for the transmission losses caused by high-frequency bands.

[0112] For a given antenna array, whose aperture is denoted as D, its electromagnetic field (EM) can be divided into a near field and a far field. As shown in Figure 1a, which is a schematic diagram of the near and far fields illustrating an exemplary embodiment of this disclosure, the boundary between the near and far fields is shown. This is known as the Rayleigh distance. Here, λ represents the wavelength. The size of the near-field range depends on both the antenna aperture (D) and the wavelength (λ).

[0113] Figure 1b is a schematic diagram illustrating far-field UE electromagnetic wave reception according to an exemplary embodiment of this disclosure. As shown in Figure 1b, for a UE in the far field, the electromagnetic waves arriving at the UE from its different antenna ports or elements are plane waves, and the beam targeting the UE is a two-dimensional (2D) directional beam pointing towards the target UE. For any path in multipath propagation, the time and phase of arrival at the UE receiving antenna array are equally spaced.

[0114] Figure 1c is a schematic diagram illustrating near-field UE electromagnetic wave reception according to an exemplary embodiment of this disclosure. As shown in Figure 1c, if the UE is located in the near field, the electromagnetic wave received by the UE is a spherical wave, and the beam targeting the UE is a three-dimensional (3D) beam surrounding the target UE. For any path in multipath propagation, the time and phase of arrival at the UE receiving antenna array will no longer be equally spaced.

[0115] For near-field UEs, the distances to the UE from different ports will vary significantly. Therefore, the optimal beams to the terminal from different ports may be different. If the terminal reports the same optimal beam when performing beam measurement, it may affect beam management and reduce communication efficiency.

[0116] Therefore, in this disclosure, a terminal sends reference signal measurement results to a network device, and when certain conditions are met, sends first information corresponding to the reference signal measurement results to the network device. This first information is port-related information corresponding to the reference signal measurement results, enabling port information reporting in certain situations. Since the optimal beam may differ for different ports, this allows the network device to better manage beam and improve communication efficiency.

[0117] The communication devices mentioned in this disclosure may include, but are not limited to, terminals, network devices, etc.

[0118] The port in this disclosure may also be referred to as a subarray, antenna element, antenna array subgroup, antenna element group, etc., and this disclosure does not limit it.

[0119] Figure 1d is a schematic diagram of a communication system architecture according to an embodiment of the present disclosure.

[0120] As shown in Figure 1d, the communication system 100 includes a terminal 101 and a network device 102.

[0121] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0122] In some embodiments, network device 102 may include at least one of access network device and core network device.

[0123] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0124] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0125] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0130] Figure 2 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0131] In step S2101, network device 102 sends second information to terminal 101.

[0132] In some embodiments, terminal 101 receives second information sent by network device 102.

[0133] In some embodiments, the second information is used to configure reference signal resources, which correspond to one or more ports.

[0134] In some embodiments, the network device may configure reference signal resources for the terminal, such as time-domain resources, frequency-domain resources, etc. The terminal may receive reference signals based on the configured reference signal resources. For example, the reference signal may be received based on time-domain and / or frequency-domain resources configured with second information.

[0135] In some embodiments, the name of the second information is not limited, and it may be, for example, "reference signal configuration information".

[0136] In step S2102, terminal 101 obtains the reference signal measurement results corresponding to each port based on the second information.

[0137] In some embodiments, the terminal can receive reference signals based on reference signal resources configured with second information. The reference signals received at each port are measured to obtain the reference signal measurement results for each port. The reference signal measurement results can be reported to the network device.

[0138] In some embodiments, a reference signal resource corresponds to one or more ports; that is, the reference signal measurement result for each port corresponds to a reference signal resource and the port corresponding to the reference signal resource. Therefore, the reference signal resource identifier and / or port identifier corresponding to the reference signal measurement result for each port can also be reported.

[0139] In some embodiments, the reference signal measurement results include at least one of the following: layer 1 reference signal received power (L1-RSRP); layer 1 signal to interference plus noise ratio (L1-SINR); and precoding matrix indicator (PMI).

[0140] In step S2103, network device 102 sends third information to terminal 101.

[0141] In some embodiments, terminal 101 receives third information sent by network device 102.

[0142] In some embodiments, the third information is used to instruct the terminal to report the first information. The first information is related to the port corresponding to the reference signal measurement result. Since the optimal beam may differ for different ports, when reporting the reference signal measurement result, information related to the port corresponding to the reference signal measurement result, i.e., the first information, can be considered.

[0143] In some embodiments, the third information may be carried on at least one of the following: radio resource control (RRC) signaling; downlink medium access control control element (DL MAC CE); downlink control information (DCI).

[0144] Optionally, the third information can be carried on RRC signaling. In this case, the third information can be considered a semi-static indication. For example, for a semi-static indication of third information, after receiving the third information, the terminal defaults to reporting the reference signal measurement result and the corresponding first information until the network device sends a new indication. It can be understood that RRC signaling can instruct the terminal whether to send the first information. When RRC signaling instructs the terminal to send the first information, the RRC signaling carries the third information. The terminal can then send the first information to the network device based on the third information. When RRC signaling instructs the terminal not to send the first information, the RRC signaling carries the fourth information. The fourth information is used to instruct the terminal not to report the first information. When the terminal receives the fourth information, it does not send the first information to the network device.

[0145] Optionally, the third information can be carried on DL MAC CE or DCI. The third information can then be considered a dynamic indication. For example, DL MAC CE can activate the terminal to send the first information. As another example, before the terminal reports the reference signal measurement results, DCI can instruct the terminal whether to report the first information corresponding to the reference signal measurement results, based on the actual situation.

[0146] In some embodiments, the name of the third information is not limited, and it may be, for example, "instruction information".

[0147] In step S2104, network device 102 sends fourth information to terminal 101.

[0148] In some embodiments, terminal 101 receives fourth information sent by network device 102.

[0149] In some embodiments, the fourth information is used to instruct the terminal not to report the first information. The first information is related to the port corresponding to the reference signal measurement result. Since the optimal beam may be the same for different ports, the port-related information corresponding to the reference signal measurement result, i.e., the first information, may not be reported when reporting the reference signal measurement result.

[0150] In some embodiments, the fourth information may be carried on at least one of the following: RRC signaling; DL MAC CE; DCI.

[0151] Optionally, the fourth information can be carried on RRC signaling. In this case, the fourth information can be considered a semi-static indication. For example, for a semi-static fourth information indication, after receiving the fourth information, the terminal defaults to reporting the reference signal measurement result but does not report the first information corresponding to the reference signal measurement result until the network device sends a new indication. It can be understood that RRC signaling can instruct the terminal whether to send the first information. When RRC signaling instructs the terminal to send the first information, the RRC signaling carries the third information. The terminal can send the first information to the network device based on the third information. When RRC signaling instructs the terminal not to send the first information, the RRC signaling carries the fourth information. The fourth information is used to instruct the terminal not to report the first information. When the terminal receives the fourth information, the terminal does not send the first information to the network device.

[0152] Optionally, the fourth information can be carried on DL MAC CE or DCI. In this case, the fourth information can be considered a dynamic indication. For example, DL MAC CE can activate the terminal to not send the first information. As another example, DCI can instruct the terminal whether to report the first information corresponding to the reference signal measurement result before the terminal reports it, based on the actual situation.

[0153] In some embodiments, the name of the fourth information is not limited, and it may be, for example, "instruction information".

[0154] The dashed lines in Figure 2 for steps S2103 and S2104 indicate that steps S2103 and S2104 are optional in different embodiments. For example, step S2103 can be omitted, and step S2104 can be executed. That is, the network device can instruct the terminal not to send the first information through the fourth information. The terminal can determine not to send the first information based on the fourth information. Of course, it can also receive the fourth information, but determine to send the first information according to the actual situation. For another example, step S2104 can be omitted, and step S2103 can be executed. That is, the network device can instruct the terminal to send the first information through the third information. The terminal can determine to send the first information based on the third information. Of course, it can also receive the third information, but determine not to send the first information according to the actual situation. For yet another example, steps S2103 and S2104 can both be omitted, and the terminal determines whether to report the first information itself.

[0155] In step S2105, terminal 101 sends first information to network device 102.

[0156] In some embodiments, network device 102 receives first information sent by terminal 101.

[0157] In some embodiments, the first information is related to the port corresponding to the reference signal measurement result. The first information includes at least one of the following: indication information, which indicates whether the first information contains a port identifier; the number of port identifiers contained in the first information; and the port identifier.

[0158] Optionally, the first information includes indication information, which indicates whether the first information contains a port identifier. That is, the first information may indicate that the first information contains a port identifier, or it may indicate that the first information does not contain a port identifier. For example, when a network device instructs a terminal to report the first information via third information, if the terminal determines that the difference between the measurement results of the reference signals corresponding to different ports is greater than a threshold, it can report the port identifier of the port corresponding to the reference signal result, indicating that the first information contains a port identifier. If the terminal determines that the difference between the measurement results of the reference signals corresponding to different ports is less than or equal to the threshold, it can not report the port identifier, indicating that the first information does not contain a port identifier. It can be understood that if the first information indicates that a port identifier is included, the network device can then obtain the port identifier from the first information to facilitate different beam management schemes for different ports. If the first information indicates that a port identifier is not included, the network device may not continue to obtain other information in the first information. In order to improve efficiency, the network device can have the same beam management scheme for different ports.

[0159] Optionally, the first information includes the number of port identifiers. That is, the number of port identifiers included in the first information can be reported. The number of port identifiers can have the same function as the indication information; for example, when the number of port identifiers is 0, it means that the first information does not contain any port identifiers. The number of port identifiers can also be used to represent port identifiers. For example, the first information can report one port identifier and the number of port identifiers, then the remaining port identifiers are multiple port identifiers consecutive to the reported port identifier. For example, if the first information reports port identifier #0 and the number 3, then the port identifiers are #0, #1, and #2. Of course, the above-mentioned port identifiers and the number of port identifiers are merely exemplary examples and are not limited thereto.

[0160] Optionally, the first information may include a port identifier. For example, the port identifier may be reported when the indication information indicates that the first information includes a port identifier. Alternatively, the first information may not include the indication information and may only include the port identifier.

[0161] In some embodiments, the reference signal resource corresponds to one or more ports. Therefore, the first information may further include a reference signal resource identifier corresponding to each reference signal measurement result. Alternatively, the terminal may send the reference signal resource identifier corresponding to the reference signal measurement result independently of the first information. That is, each reference signal measurement result corresponds to a reference signal resource and a port corresponding to the reference signal resource. Therefore, the reference signal resource identifier and / or port identifier corresponding to each reference signal measurement result can be reported.

[0162] In some embodiments, a port identifier can be an identifier for a single port or an identifier for a port group. A single port can be a single antenna element or a port composed of multiple antenna elements. A port group can represent a group of multiple ports. For example, when the terminal's ports are divided too finely, multiple ports can be grouped into a port group, and the identifier of the port group can be reported. In this case, the number of port identifiers in the first information is the number of port groups. When the port identifier is the identifier of a port group, the number of port identifiers is less than the actual number of ports on the terminal.

[0163] In some embodiments, the terminal may send first information to the network device when preset conditions are met. This first information is related to the port corresponding to the reference signal measurement result sent by the terminal to the network device. That is, the terminal may send the reference signal measurement result to the network device and, when preset conditions are met, send first information related to the port corresponding to that reference signal measurement result. For example, network device 102 may receive the reference signal measurement result sent by terminal 101. In this case, terminal 101 determines that the conditions are not met and does not send the first information corresponding to the reference signal measurement result. Network device 102 may receive the reference signal measurement result and the first information corresponding to the reference signal measurement result sent by terminal 101. In this case, terminal 101 determines that the conditions are met and sends the first information corresponding to the reference signal measurement result.

[0164] In some embodiments, the preset conditions include at least one of the following: receiving third information sent by a network device, the third information being used to instruct the terminal to report first information; and the difference between the measurement results of reference signals corresponding to different ports being greater than a threshold.

[0165] Optionally, the preset condition can be receiving third information sent by the network device. That is, when the terminal receives the third information sent by the network device, the terminal determines that the preset condition is met, and at this time, it can send the first information to the network device.

[0166] Optionally, the preset condition could be that the difference between the measurement results of the reference signals corresponding to different ports is greater than a threshold. For example, the network device does not send the third and fourth information. That is, the network device does not instruct the terminal whether to send the first information. The terminal determines to send the first information based on the fact that the difference between the measurement results of the reference signals corresponding to different ports is greater than the threshold. Conversely, if the difference between the measurement results of the reference signals corresponding to different ports is less than or equal to the threshold, the first information may not be sent. For another example, the network device sends the fourth information, but the difference between the measurement results of the reference signals corresponding to different ports is greater than the threshold, the terminal can still send the first information. That is, even if the network device instructs the terminal not to send the first information, the terminal may still send the first information if it determines that it needs to be sent based on the actual situation. Wherein, if the difference between the measurement results of the reference signals corresponding to different ports is greater than the threshold, it can be considered that the beams corresponding to different ports may be different, and the first information needs to be reported to avoid problems such as poor beam management and low communication efficiency of the terminal. For example, when the terminal is in the near field, the difference between the measurement results of the reference signals corresponding to different ports may be greater than the threshold. Therefore, by reporting the first information when the difference between the measurement results of the reference signals corresponding to different ports is greater than the threshold, the problem of poor beam management and low communication efficiency of the near field terminal can be effectively avoided.

[0167] In some embodiments, the reference signal measurement results may be carried on at least one of the following: beam reporting; reporting of a precoding matrix indicator (PMI). In this case, the reference signal measurement results and the first information are carried by the same signaling.

[0168] In some embodiments, the first information may be carried on at least one of the following: uplink medium access control control element (UL MAC CE); uplink control information (UCI); beam report; or report to PMI.

[0169] In some embodiments, the reference signal measurement result and the first information can be carried by the same signaling, for example, by a beam report or a report submitted to the PMI. The reference signal measurement result and the first information can also be carried by different signaling. For example, the reference information measurement result can be carried based on a beam report or a PMI report. The first information is carried by UL MAC CE or UCI.

[0170] In some embodiments, the name of the first information is not limited, and it may be, for example, "reported information".

[0171] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2105. Each of steps S2101 to S2105 can be a separate embodiment, and the embodiments can be arbitrarily combined and implemented in different orders without contradiction. For example, step S2105 can be implemented as an independent embodiment, but it is not limited thereto.

[0172] In some embodiments, certain steps are optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, steps S2103 and S2104 are optional.

[0173] In some embodiments, other optional implementations may be described before or after the specification corresponding to FIG2.

[0229] Figure 5 is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 5, this disclosure relates to a communication method, which includes:

[0230] In step S5101, terminal 101 sends first information to network device 102.

[0231] The optional implementation of step S5101 can be found in S2101 of Figure 2, and other related parts in the embodiments involved in Figure 2, which will not be repeated here.

[0232] In step S5102, network device 102 receives the first information sent by terminal 101.

[0233] The optional implementation of step S5102 can be found in S2101 of Figure 2, and other related parts in the embodiments involved in Figure 2, which will not be repeated here.

[0234] In some embodiments, the above methods may include the methods of the embodiments related to the communication system 100, terminal 101, network device 102, etc., which will not be described again here.

[0235] This disclosure also provides a communication method, as follows:

[0236] In some embodiments, the terminal determines the content of the first report. The content of the first report includes a first content or a second content. The first content includes first information, which includes information about the port (also referred to as a subarray, antenna element, antenna array, or antenna element group, etc.) of the reference signal resource corresponding to the measurement quality in the first report.

[0237] In some embodiments, the second content does not include the first information.

[0238] In some embodiments, the first report may be, for example, a beamforming report or a PMI report. When the first report includes first content, it includes reference signal measurement results and first information. The reference signal measurement results and measurement quality can be used interchangeably. When the first report includes second content, it includes only the reference signal measurement results and does not include the first information.

[0239] In some embodiments, the first information includes at least one of the following

[0240] a) Whether the port identifier appears.

[0241] In some embodiments, the absence of port identifiers indicates that the measurement quality of the beam is approximately the same across all ports, and there is no need to distinguish between different ports. The presence of port identifiers indicates that the measurement quality varies significantly across different ports, and it is necessary to distinguish between them.

[0242] b) The number of corresponding port identifiers.

[0243] In some embodiments, if the number is greater than 1 but less than the total number of ports, it indicates that the ports are divided too finely for the terminal. More antenna elements can be combined into one port, or more ports can be combined into a port group.

[0244] c) The corresponding port identifier.

[0245] In some embodiments, if a port identifier is present, then one or more port identifiers need to be indicated.

[0246] In some embodiments, the terminal receives first configuration information, which includes reference signal resource configuration information, and the reference signal resources correspond to multiple ports.

[0247] In some embodiments, the first configuration information may be the second information described in the above embodiments.

[0248] In some embodiments, the terminal obtains measurement quality information corresponding to each of the multiple ports of the reference signal resource and reports the measurement quality information.

[0249] In some embodiments, the measured quality information includes L1-RSRP or L1-SINR.

[0250] In some embodiments, the first report may also include a reference signal resource identifier.

[0251] In some embodiments, such as when the first report is a beam report, it includes a reference signal resource identifier, first information, L1-RSRP, or L1-SINR.

[0252] In some embodiments, if the first information indicates the presence of a port identifier, it includes at least one port identifier.

[0253] In some embodiments, if the first information indicates multiple port identifiers, it includes multiple port identifiers; or it includes one port identifier and a number of port identifiers (identifying multiple port identifiers consecutive to the one port identifier. The one port identifier is the smallest of the multiple port identifiers).

[0254] In some embodiments, the first information is included in the first report.

[0255] In some embodiments, the first information is included in the first report, and the first information is sent based on UL MAC CE or UCI.

[0256] In some embodiments, the terminal receives third information from the base station, the third information being used to indicate whether the terminal's first report contains first content or second content.

[0257] In some embodiments, the base station determines whether the terminal should report port information, rather than the terminal determining and reporting it itself.

[0258] In some embodiments, the second information is sent based on RRC, DL MAC CE, or DCI.

[0259] In some embodiments, RRC-based indications are semi-static. For example, RRC instructs the terminal to report a first report based on near-field or far-field status, where near-field corresponds to first content and far-field corresponds to second content. Alternatively, RRC configures the terminal's first information to include either first or second content.
