[0002] In wireless communication, the transmission of signals is affected by various factors. For example, when there are obstacles between the receiving end and the transmitting end, it will have different effects on the channel environments of multiple channels between the receiving end and the transmitting end, resulting in deviations in the signals received by the receiving end through multiple channels.

[0003] However, the current channel measurement feedback is difficult to measure the signal deviation effects caused by the above situations, thus affecting the transmission quality of signals. Summary of the Invention

[0033] Next, the technical solutions in the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0034] It should be noted that in this disclosure, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0035] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0036] In the description of this disclosure, unless otherwise specified, " / " means "or". For example, A / B may represent A or B. The "and / or" herein is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, "at least one" means one or more, and "multiple" means two or more.

[0037] In wireless communication, the transmission of signals is affected by various factors. To further improve the signal transmission quality, related solutions usually assist the communication device to adjust the transmission strategy (such as precoding, resource scheduling) by means of channel measurement feedback.

[0038] Among them, the current channel measurement feedback includes downlink channel measurement feedback and uplink channel measurement feedback.

[0039] In one example, as Figure 1 shown, the downlink channel measurement feedback mainly includes the following steps:

[0040] Step 101, the base station sends measurement configuration information to the terminal. Correspondingly, the terminal receives the measurement configuration information from the base station.

[0041] Among them, the measurement configuration information includes resource configuration information and feedback configuration information. The resource configuration information includes the downlink reference signals that the terminal needs to measure. The feedback configuration information includes relevant parameters for the terminal to feedback, such as the report quantity, the time-domain characteristics of the feedback (such as period, semi-persistent, aperiodic), codebook configuration information, the frequency-domain granularity of the pre-coding matrix indication (PMI) and the channel quality indication (CQI), measurement constraint configuration parameters, etc.

[0042] Exemplarily, the feedback amount is used to indicate the content that the terminal needs to feedback. For example, when the feedback amount is configured as "cri-RI-PMI-CQI" or "cri-RI-LI-PMI-CQI", it means that the terminal needs to feedback codebook-related parameters (such as PMI).

[0043] In some examples, the above measurement configuration information can be sent by the base station to the terminal through radio resource control (RRC) signaling, medium access control (MAC) control element (CE), or downlink control information (DCI).

[0044] Step 102: The base station sends a trigger signaling to the terminal. Correspondingly, the terminal receives the trigger signaling from the base station.

[0045] Among them, the above step 102 is an optional step. For aperiodic and semi-persistent downlink channel measurement feedback, the base station can also trigger the measurement feedback operation of the terminal through the trigger signaling.

[0046] Step 103: The base station sends a downlink reference signal to the terminal. Correspondingly, the terminal receives the downlink reference signal from the base station.

[0047] Among them, the terminal can perform channel measurement based on the received downlink reference signal, so as to generate corresponding feedback information. This feedback information is used to feedback the channel state between the base station and the terminal.

[0048] Step 104: The terminal sends feedback information to the base station. Correspondingly, the base station receives the feedback information from the terminal.

[0049] Exemplarily, the terminal can send feedback information to the base station through the physical uplink shared channel (PUSCH) or the physical uplink control channel (PUCCH).

[0050] In yet another example, as Figure 2 shown, the uplink channel measurement feedback mainly includes the following steps:

[0051] Step 201: The base station sends measurement configuration information to the terminal. Correspondingly, the terminal receives the measurement configuration information from the base station.

[0052] Among them, the measurement configuration information includes usage indication (usage) information, transmission period, transmission resource, antenna port configuration, and other information.

[0053] Step 202: The base station sends a trigger signaling to the terminal. Correspondingly, the terminal receives the trigger signaling from the base station.

[0054] Among them, the above step 202 is an optional step. For aperiodic and semi-persistent uplink channel measurement feedback, the base station can also trigger the terminal's reference signal transmission operation through the trigger signaling.

[0055] Step 203: The terminal sends an uplink reference signal to the base station. Correspondingly, the base station receives the uplink reference signal from the terminal.

[0056] Among them, the terminal can send the uplink reference signal according to the transmission resources configured by the measurement configuration information, and the base station performs measurements based on the received uplink reference signal.

[0057] Step 204: The base station sends feedback information to the terminal. Correspondingly, the terminal receives the feedback information from the base station.

[0058] However, the above channel measurement feedback still has certain limitations and is difficult to measure and feedback the influence of the channel environment in some cases, thus affecting the overall performance of the communication system.

[0059] In one example, when there is an obstacle between the transmitter and the receiver, if the obstacle only blocks some ports, it may cause a significant gap between the actual signal powers of the signals sent by different ports, thus affecting the normal wireless communication between the transmitter and the receiver. This phenomenon is also called the spatial non-stationary phenomenon.

[0060] In another example, in current wireless communication, electromagnetic wave signals are usually processed as ideal plane waves. However, in most cases, electromagnetic wave signals do not propagate in the form of plane waves. For example, in the near-field communication scenario, electromagnetic wave signals usually show an obvious spherical wavefront, which leads to a large phase difference between different ports, and this phase difference is non-linearly changing, thus affecting wireless communication.

[0061] In another example, due to the influence of errors caused by the hardware design of the communication device and the realization of production technology, there will be inherent differences between different ports of the communication device, and this difference will also affect the coherent transmission ability of the communication device, thus affecting wireless communication.

[0062] In summary, the current channel measurement feedback is difficult to measure the influence of signal deviation caused by the above situations. For example, the problem of large and non-obvious regular differences in the actual power and phase between different ports in the above examples will affect the transmission quality of the final signal.

[0063] In view of this, in the embodiments of the present disclosure, the first node may receive a reference signal from the second node and send measurement feedback information determined based on the reference signal to the second node. Since the measurement feedback information includes power measurement information and / or phase measurement information, the present disclosure can feedback the actual power and / or phase conditions of the signal in the current communication environment to the sending end, thereby facilitating subsequent corresponding adjustments by the sending end and improving the transmission quality of the signal.

[0064] The technical solutions of the embodiments of the present disclosure can be applied to various communication systems. The communication system can be a third generation partnership project (3GPP) communication system, for example, a fourth generation (4G) system such as a long term evolution (LTE) system, a fifth generation (5G) system such as a new radio (NR) system, a system combining LTE and 5G, a communication and sensing integrated system, a non-terrestrial network (NTN), a device-to-device (D2D) communication system, a vehicle to everything (V2X) communication system, a machine-type communication (MTC) system, an internet of things (IoT) system, a satellite communication system, a short-range system, a global system for mobile communications (GSM), an enhanced data rate for GSM evolution (EDGE), a wideband code division multiple access system (WCDMA), a code division multiple access 2000 system (CDMA2000), a time division-synchronization code division multiple access system (TD-SCDMA), or other future communication systems. The communication system can also be a non-3GPP communication system, without limitation.

[0065] In this example, the network architecture of the mobile communication network may at least include a first node and a second node.

[0066] It should be understood that the nodes in the embodiments of the present disclosure may be various communication devices in the above communication system. For example, the first node may be a node that measures a reference signal in a measurement feedback scenario, and the second node may be a node that receives measurement information in a measurement feedback scenario. The measurement feedback method provided by the present disclosure is applicable to both downlink measurements and uplink measurements. For downlink measurements, the first node may be a terminal-side device (such as, but not limited to, a terminal), and the second node may be a network-side device (such as, but not limited to, a base station). For uplink measurements, the first node may be a network-side device, and the second node may be a terminal-side device. In addition, the first node and the second node may also be modules of devices in the communication system, or entities of protocol layers (such as, but not limited to, the RLC layer) in the communication system. The module may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0067] Exemplarily, as Figure 3 shown, a communication system provided by an embodiment of the present disclosure includes a base station 301 and a terminal 302. The base station 301 and the terminal 302 may be one or more, and the quantity is not limited.

[0068] Among them, the base station 301 and the terminal 302 are connected through a communication link. The communication link may be a wired communication link or a wireless communication link, and the present disclosure does not limit this.

[0069] In some embodiments, the base station 301 is a device located on the access network side of the above communication system and having a wireless transceiver function, or a chip or chip system that can be disposed in the device. The base station 301 includes, but is not limited to: access points (APs) in a wireless fidelity (WiFi) system, such as home gateways, routers, servers, switches, bridges, etc., evolved NodeBs (eNBs), radio network controllers (RNCs), NodeBs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home evolved NodeBs, or home NodeBs, HNBs), base band units (BBUs), wireless relay nodes, wireless backhaul nodes (e.g., integrated access and backhaul (IAB) nodes), transmission and reception points (TRPs or transmission points, TPs), etc. It can also be a 5G base station, such as a gNB in a new radio (NR) system, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or it can also be a network node constituting a gNB or a transmission point, such as a base band unit (BBU), or a distributed unit (DU), a road side unit (RSU) with base station functions, or a 5G radio access network (NG-Ran) device, a 6G base station, etc. The base station 301 also includes base stations in different networking modes, such as master evolved NodeBs (MeNBs), secondary eNBs (SeNBs, or secondary gNBs, SgNBs). The base station 301 also includes different types, such as terrestrial base stations, aerial base stations, and satellite base stations, etc.

[0070] In some embodiments, the terminal 302 is a device with wireless communication capabilities. It can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted. It can also be deployed on water (such as ships, etc.). It can further be deployed in the air (such as airplanes, balloons, satellites, etc.). The terminal 302 is also known as user equipment (UE), mobile station (MS), mobile terminal (MT), and terminal device, etc. It is a device that provides voice and / or data connectivity to users. For example, the terminal 302 includes handheld devices with wireless connection capabilities, vehicle-mounted devices, etc. Currently, the terminal 302 can be: mobile phones, tablet computers, laptop computers, palmtop computers, mobile internet devices (MID), wearable devices (such as smart watches, smart bracelets, pedometers, etc.), vehicle-mounted devices (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed rails, etc.), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, smart home devices (such as refrigerators, TVs, air conditioners, electricity meters, etc.), smart robots, workshop devices, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grid, wireless terminals in transportation safety, wireless terminals in smart city, or wireless terminals in smart home, flying devices (such as smart robots, hot air balloons, drones, airplanes), etc. In a possible application scenario of the present disclosure, the terminal is a terminal that often works on the ground, such as a vehicle-mounted device. In the present disclosure, for the convenience of description, the chips deployed in the above devices, such as system-on-a-chip (SOC), baseband chips, etc., or other chips with communication capabilities can also be referred to as terminals.

[0071] It should be noted that the embodiments of the present disclosure can draw on or refer to each other. For example, the same or similar steps, method embodiments, system embodiments, and device embodiments can all refer to each other without limitation.

[0072] The following combines Figure 3 the communication system shown to describe the measurement feedback method provided by the embodiments of the present disclosure.

[0073] Taking the first node as an example,Figure 4 The flowchart of a measurement feedback method provided by an embodiment of the present disclosure. As Figure 4 shown, the method includes the following steps:

[0074] Step 401, receive a reference signal from a second node.

[0075] Exemplarily, the embodiments of the present disclosure are applicable to downlink measurement and uplink measurement. For downlink measurement, the reference signal may be a downlink reference signal, such as a channel state information reference signal (CSI-RS). For uplink measurement, the reference signal may be an uplink reference signal, such as a sounding reference signal (SRS).

[0076] Step 402, send measurement feedback information determined based on the reference signal to the second node.

[0077] Wherein, the measurement feedback information includes power measurement information and / or phase measurement information.

[0078] Exemplarily, the first node may measure the received reference signal to generate the measurement feedback information. For downlink measurement, the first node may feedback the measurement feedback information through PUSCH / PUCCH. For uplink measurement, the first node may feedback the measurement feedback information through DCI.

[0079] In some embodiments, the power measurement information may be power information measured by the first node, and the phase measurement information may be phase information measured by the first node.

[0080] Exemplarily, the power information may be determined by measuring the signal strength (or signal quality), such as measuring the reference signal received power (RSRP), reference signal received quality (RSRQ), and signal-to-interference plus noise ratio (SINR) of the reference signal. The phase information may be determined by measuring the electromagnetic wave phase of the reference signal.

[0081] Wherein, in the embodiments of the present disclosure, the above power information and phase information may be measured in multiple granularities, such as port granularity, port group granularity, or reference signal resource granularity. For relevant introductions, reference may be made to the subsequent descriptions, which will not be elaborated here.

[0082] Thus, in the present disclosure, the second node can perform operations such as port selection, port power allocation, selection and generation of near-field codebooks, etc., based on the power measurement information and / or phase measurement information fed back by the first node. This method can effectively assist the communication device in improving communication performance, increasing the utilization rate of wireless resources, and fully utilizing the near-field effect to optimize communication quality. In addition, this method can also assist the communication system in adapting to different wireless environments, improving the robustness of the system, and providing technical support for future high-efficiency and intelligent wireless communication networks.

[0083] It should be understood that current channel measurement feedback is difficult to measure the signal deviation effects caused by some situations. Taking codebook-based channel measurement as an example, the receiving end obtains the codeword with the maximum equivalent channel gain through channel measurement and feeds back the PMI corresponding to the codeword to the transmitting end. The transmitting end performs precoding based on the received PMI, thereby realizing beamforming. This scheme can make the electromagnetic wave signal form a beam propagating in a specific direction. However, this scheme still has problems of poor and irregular differences in power and phase, which affect the transmission quality of the signal.

[0084] Based on the above technical solution, in the present disclosure, the first node can receive the reference signal from the second node and send the measurement feedback information determined based on the reference signal to the second node. Since the measurement feedback information includes power measurement information and / or phase measurement information, the present disclosure can thus feed back the actual power and / or phase conditions of the signal in the current communication environment to the transmitting end, thereby facilitating subsequent corresponding adjustments by the transmitting end and improving the transmission quality of the signal.

[0085] The above technical solution of the present disclosure is applicable to various measurement feedback scenarios, and the following will be introduced by taking downlink measurement feedback and uplink measurement feedback as examples respectively.

[0086] I. Downlink measurement feedback.

[0087] At this time, the first node can be a terminal, and the second node can be a base station.

[0088] As an embodiment provided by the present disclosure, the above power measurement information can be power information at the port granularity or power information at the port group granularity.

[0089] In some embodiments, the power measurement information includes the power information of at least one port for transmitting the reference signal.

[0090] Exemplarily, the power information of the port includes one of the following:

[0091] The power metric value of the port, the power offset value of the port, the power number of the port.

[0092] Among them, the power offset value of the port is used to characterize the difference in the power measurement value between the port and the reference port, and the power number is used to indicate the power measurement value or the power offset value.

[0093] In one example, the power measurement information includes the power measurement value of each of the at least one port.

[0094] Taking the number of at least one port for transmitting the reference signal as N, where N is an integer greater than 0, the port numbers of the at least one port can be port0, port1,..., portN-1.

[0095] Among them, the power measurement information can be represented in the form of a bitmap, that is, represented as a set of numerical values. The number of numerical values corresponds to the number of at least one port for transmitting the reference signal. For example, one numerical value corresponds to one port, and the nth numerical value is the power measurement value of the port with the port number portn-1. This numerical value can be represented according to a fixed number of bits according to actual requirements. The power measurement value can be determined by RSRP or SINR.

[0096] In yet another example, the power measurement information may include at least one of the following: first power information, second power information.

[0097] Among them, the first power information may be the power measurement value of the reference port, and the second power information may be the power offset value of other ports among the at least one port. The second power information can be represented in the form of a bitmap, that is, represented as a set of numerical values. This set of numerical values corresponds one-to-one in sequence with other ports among the at least one port, and this numerical value represents the difference between the power measurement value of the corresponding port and the power measurement value of the reference port. Since generally the power offset value is much smaller than the power measurement value, reporting the power offset value can save signaling overhead.

[0098] Taking the power measurement value as RSRP and the reference port as port0 as an example, the first power information is: RSRP0, and the second power information is: (RSRP0-RSRP1)(RSRP0-RSRP2)...(RSRP0-RSRP n )...(RSRP0-RSRP N-1 ), where, RSRP n is the RSRP corresponding to the port with the port number port n-1.

[0099] In yet another example, the power measurement value and the power deviation value in the above example can also be represented by a power number. For example, the first node and the first node can configure a mapping table between the power number and the power measurement value / power deviation value. In this way, the first node can feedback the power measurement value / power deviation value by feeding back the power number, thereby reducing signaling overhead.

[0100] In some embodiments, the power measurement information further includes port information of at least one port; and / or, the power measurement information further includes port information of a reference port.

[0101] In some examples, the port information may be a port number. The port information of the at least one port and the port information of the reference port may also be determined in other ways. For example, it may be determined by means of protocol pre - definition, or by means of high - layer signaling configuration. The reference port may be a port among the at least one port, or may be another port other than the at least one port. For example, if the power measurement information does not have the port information of the reference port, the first port among the at least one port may be defaulted as the reference port, or the first port among all ports may be defaulted as the reference port.

[0102] In some embodiments, the port information of the at least one port includes one of the following:

[0103] Port numbers of one or more ports among the at least one port;

[0104] The port number and port interval of a target port among the at least one port.

[0105] Exemplarily, the port numbers of one or more ports among the at least one port may be the port numbers of the starting port and the ending port among the at least one port. That is to say, at this time, the first node feeds back the power information of the starting port, the ending port, and each port between the starting port and the ending port.

[0106] Exemplarily, the port numbers of one or more ports among the at least one port may also be the port numbers of the ports for which the power information is to be fed back. That is to say, at this time, the first node feeds back the power information of the one or more ports.

[0107] Exemplarily, if the power measurement information does not have the port information of the at least one port, the first node may feed back the power information of each port. For example, if the number of ports for sending reference signals is N, the port numbers corresponding to the power information of each port fed back by the first node are port0, port1,..., portN - 1.

[0108] Exemplarily, for the port number and port interval of a target port among the at least one port, the target port may be the first port among the at least one port to be fed back. For example, the port information of the at least one port includes port number 2 and port interval 4. When the total number of ports is 16, it means that the ports to be fed back are port2, port6, port10, port14.

[0109] In some examples, the port information of the reference port may be the port number of the reference port or the index of the reference port among the at least one port above.

[0110] Combined with the above examples, the ports fed back by the port information of the at least one port are port2, port6, port10, and port14 respectively. The port information of the reference port is 3. When the port information of the reference port is the port number, it means the reference port is port3. The first node feeds back the power information of port2, port6, port10, and port14 with port3 as the reference port. When the port information of the reference port is the index, it means the reference port is the 3rd port among the above ports, that is, port10. The first node feeds back the power information of port2, port6, port10, and port14 with port10 as the reference port.

[0111] In some examples, the port information of the reference port can also be determined in other ways. For example, it can be determined by the protocol pre - defined method, or by high - layer signaling configuration.

[0112] In some embodiments, the power measurement information includes the power information of at least one port group. The port group includes multiple ports for transmitting reference signals.

[0113] Exemplarily, the power information of the port group includes one of the following:

[0114] The power metric value of the port group, the power offset value of the port group, the power number of the port group.

[0115] Among them, the power metric value of the port group is determined by the power metric values of each port in the port group. The power offset value of the port group is used to characterize the difference in the power metric values between the port group and the reference port group, and the power number is used to indicate the corresponding power metric value or power offset value.

[0116] In one example, the power measurement information includes the power metric value of each of the at least one port group.

[0117] Among them, the power measurement information can be represented in the form of a bitmap, that is, represented as a set of numerical values. The number of numerical values corresponds to the number of the at least one port group. For example, one numerical value corresponds to one port group. The power metric value of the port group can be determined by the RSRP or SINR of multiple ports in the port group. For example, the power metric value of the port group can be the average value of the RSRP of multiple ports in the port group, the sum of the RSRP of multiple ports, or the average value of the SINR of multiple ports.

[0118] In some embodiments, the power measurement information further includes port group information of at least one port group; and / or, the power measurement information further includes port group information of a reference port group.

[0119] The port group information of the at least one port group and the reference port group may also be determined in other ways, such as by a protocol predefined manner, or by high-level signaling configuration. The reference port group may be a port group in the at least one port group, or may be a port group other than the at least one port group. For example, if the power measurement information does not have the port group information of the reference port group, the first port group may be defaulted as the reference port group.

[0120] In some embodiments, the port group information of at least one port group includes one of the following:

[0121] a port group number of one or more port groups in at least one port group;

[0122] The port number of the starting port of one or more port groups in at least one port group.

[0123] The port number of the end port of one or more port groups in at least one port group.

[0124] The first grouping step length is a step length of a first dimension of any port group in at least one port group in a polarization direction of the antenna array to which it belongs.

[0125] The second grouping step length is a step length of a second dimension of any port group in at least one port group in a polarization direction of the antenna array to which it belongs.

[0126] Exemplarily, the port group number of one or more port groups in the at least one port group may be the port group number of the port group to be fed back by the first node. If the power measurement information does not have the port group information of at least one port group, the first node may feed back the power information of all port groups.

[0127] Exemplarily, the port group information may include multiple port numbers, the number of which is a multiple of 2. Wherein, every two port numbers correspond to the port number of the start port and the port number of the end port of a port group, and the remaining ports constitute the remaining port group.

[0128] For example, when there are two port groups, the port group information may be two port numbers corresponding to the port number of the start port and the port number of the end port of one of the port groups, and the remaining ports constitute another port group.

[0129] Exemplarily, the port group information may include the port numbers of the starting ports of the port groups other than the first port group in at least one port group, or the port group information may include the port numbers of the ending ports of the port groups other than the last port group in at least one port group. That is to say, the port group information may feedback the breakpoints of the port groups. For example, it may be the port number of one of the two adjacent ports of two port groups (i.e., the ending port of one port group and the starting port of the other port group). In this way, the feedback port group information can be reduced, thereby reducing the signaling overhead. Taking the port group information including the port numbers of the ending ports of the port groups other than the last port group in at least one port group as an example, if the port numbers included in the port group information are 4, 8, 18 and the total number of ports is 32, it means there are 4 port groups. The first port group corresponds to port0 to port4, the second port group corresponds to port5 to port8, the third port group corresponds to port9 to port18, and the fourth port group corresponds to port19 to port31.

[0130] Exemplarily, the port group information may further include a first grouping step size n1 and a second grouping step size n2. This method is applicable to the case where the port groups are regularly arranged. As Figure 5 shown, the number of ports in the first dimension in one polarization direction of the antenna array is N1, and the number of ports in the second dimension in one polarization direction of the antenna array is N2. In this way, the port grouping situation can be determined. Among them, N1 and N2 can be obtained through high-layer signaling configuration. Taking N1 = 8, N2 = 4, n1 = 4, n2 = 2 as an example, it means there are 4 port groups, and each port group includes 8 ports.

[0131] Exemplarily, the port group information may further include the first grouping step size or the second grouping step size. For example, for the case where the number of ports in the first dimension in one polarization direction of the antenna array is 1, the port grouping situation can be determined only by the second grouping step size at this time. Another example is that for the case where the number of ports in the second dimension in one polarization direction of the antenna array is 1, the port grouping situation can be determined only by the first grouping step size at this time.

[0132] In yet another example, the power measurement information includes at least one of the following: first power information, second power information, the power metric value of the reference port group, and the power offset values of the other port groups in at least one port group.

[0133] Among them, the first power information may be the power metric value of the reference port group, and the second power information may be the power offset value of other port groups in at least one port group. The second power information may be represented in the form of a bitmap, that is, represented as a set of numerical values, and this set of numerical values corresponds one by one in sequence to other port groups in at least one port group, and this numerical value represents the difference between the power metric value of the corresponding port group and the power metric value of the reference port group.

[0134] In yet another example, the power metric value and the power deviation value in the above example may also be represented by power numbers, which will not be elaborated here.

[0135] In some embodiments, the first node may feedback the phase information of each port, or may feedback the phase information of some ports.

[0136] In one example, the phase measurement information includes the phase information of at least one port for transmitting a reference signal.

[0137] Exemplarily, the phase information of the port includes one of the following:

[0138] The phase metric value of the port, the phase offset value of the port, the phase number of the port.

[0139] Among them, the phase offset value of the port is used to characterize the difference between the phase metric values of the port and the reference port, and the phase number is used to indicate the corresponding phase metric value or phase offset value.

[0140] In some examples, the phase measurement information further includes the port information of at least one port; and / or, the phase measurement information further includes the port information of the reference port.

[0141] The port information of at least one port and the reference port can also be determined in other ways. For example, it can be determined by means predefined by the protocol, or for another example, it can be configured by high-layer signaling.

[0142] In yet another example, the phase measurement information includes the port information of at least one port and the phase offset value.

[0143] Among them, the phase offset value of at least one port may be a set of numerical values, and each numerical value corresponds to the port indicated in the port information in sequence. This numerical value may be the difference between the phase of the corresponding port and the phase of the reference port.

[0144] In some embodiments, the port information of at least one port includes one of the following:

[0145] The port numbers of one or more ports in at least one port;

[0146] The port number of the target port and the port interval in at least one port.

[0147] For relevant introductions, reference can be made to the above power measurement information, which will not be elaborated here.

[0148] The above embodiments respectively introduce the power measurement information and phase measurement information in the present disclosure. Among them, the first node can send power measurement information and / or phase measurement information to the second node.

[0149] When the first node sends both power measurement information and phase measurement information simultaneously, the measurement feedback information can respectively include two parts: power measurement information and phase measurement information. In this way, the power measurement information and phase measurement information can feedback measurement information of different granularities or different objects under the same granularity. For example, the power measurement information can be the power information of multiple port groups, and the phase measurement information can be the phase information of multiple ports.

[0150] In one example, as Figure 6 shown, the power measurement information and phase measurement information are divided into two parts in the measurement feedback information. The power measurement information includes the port group information and power information of the port group. The phase measurement information includes the port information of at least one port, the reference port information of the reference port, and the phase information of the at least one port. For relevant introductions, reference can be made to the above description, which will not be elaborated here.

[0151] The power measurement information and phase measurement information can also be sent in combination. For example, for the same object under the same granularity, such as the power measurement information and phase measurement information can be the power information and phase information corresponding to the same multiple ports. In this way, the signaling overhead can be further reduced.

[0152] In yet another example, the measurement feedback information includes power measurement information, phase measurement information, and the port information of at least one port. The power measurement information includes the power information of the at least one port, and the phase measurement information includes the phase information of the at least one port.

[0153] Exemplarily, as Figure 7 shown, the measurement feedback information can also include the reference port information of the reference port, the port information of at least one port, the power information of at least one port, and the phase information of at least one port. The port information of the reference port can also be determined by other means. For relevant introductions, reference can be made to the above description, which will not be elaborated here.

[0154] As an embodiment of the present disclosure, before performing the above measurement feedback, the first node can also receive the configuration information of the measurement feedback sent by the second node. Combining Figure 4 with the embodiment shown in Figure 8 shown, as

[0159] When the first parameter takes a third value, the first parameter is used to indicate that the first node feeds back power measurement information and phase measurement information.

[0160] Exemplarily, the first measurement configuration information may be CSI-ReportConfig information, and the first parameter may be a report quantity. The first node may receive the first measurement configuration information through RRC signaling, MAC CE, or DCI.

[0161] For aperiodic and semi-persistent downlink channel measurement feedback, the second node may also trigger the measurement feedback operation of the first node through a trigger signaling.

[0164] Port information of a reference port;

[0165] Port group information of at least one port group; the port group includes multiple ports for transmitting a reference signal;

[0168] Port numbers of one or more ports in at least one port;

[0169] Port number of a target port and port interval in at least one port.

[0170] In some embodiments, the port group information of at least one port group includes one of the following:

[0171] Port group numbers of one or more port groups in at least one port group;

[0172] The port numbers of the start ports of one or more port groups in at least one port group;

[0173] The port numbers of the end ports of one or more port groups in at least one port group;

[0174] The first grouping step; the first grouping step is the step in the first dimension of one polarization direction of the antenna array to which any port group in at least one port group belongs;

[0175] The second grouping step; the second grouping step is the step in the second dimension of one polarization direction of the antenna array to which any port group in at least one port group belongs.

[0176] For relevant introductions, reference can be made to the above descriptions, which will not be elaborated here.

[0177] II. Uplink measurement feedback.

[0178] At this time, the first node can be a base station, and the second node can be a terminal.

[0179] As an embodiment provided by the present disclosure, the above power measurement information and phase measurement information can be the power information and phase information of the reference signal resource granularity.

[0180] In some embodiments, the measurement feedback information may further include a first indication bit, and the first indication bit is used to indicate the coherent transmission capability of the second node.

[0181] For example, the coherent transmission capabilities include fully - coherent transmission, partial - coherent transmission, and non - coherent transmission.

[0182] In some embodiments, the power measurement information includes the power information corresponding to at least one reference signal resource.

[0183] Wherein, the reference signal resource is used to indicate one or more ports for transmitting reference signals, or the reference signal resource is used to indicate a port group. The port group includes multiple ports for transmitting reference signals.

[0184] Exemplarily, the power information corresponding to the reference signal resource is the power information of the port or port group indicated by the reference signal resource.

[0185] For example, when the reference signal resource is used to indicate one or more ports for transmitting reference signals, the power information corresponding to the reference signal resource may be the power information of the one or more ports. When the reference signal resource is used to indicate a port group, the power information corresponding to the reference signal resource may be the power information of the port group. The reference signal resource may be an SRS resource.

[0186] In some embodiments, the power information of a port includes one of the following:

[0187] The power metric value of the port, the power offset value of the port, the power number of the port.

[0188] Wherein, the power offset value of the port is used to characterize the difference in the power metric value between the port and a reference port; the power number is used to indicate the power metric value or the power offset value.

[0189] In some embodiments, the power information of a port group includes one of the following:

[0190] The power metric value of the port group, the power offset value of the port group, the power number of the port group.

[0191] Wherein, the power metric value of the port group is determined by the power metric values of each port in the port group; the power offset value of the port group is used to characterize the difference in the power metric value between the port group and a reference port group; the power number is used to indicate the corresponding power metric value or the power offset value.

[0192] For related introductions, reference may be made to the above description, which will not be elaborated here.

[0193] In some embodiments, the power measurement information further includes the identifier of one or more reference signal resources in at least one reference signal resource; and / or, the power measurement information further includes the identifier of the reference signal resource indicating the reference port or the reference port group.

[0194] Exemplarily, the identifier of the reference signal resource may be an SRS resource indicator (SRI).

[0195] In one example, the power measurement information may include at least one of the following: a first identifier, a second identifier, and power information.

[0196] Wherein, the first identifier may be the identifier of the reference signal resource indicating the reference port / reference port group, and the first identifier may also be determined by other means, for example, it may be determined by a pre-defined protocol, or it may be configured by a high-layer signaling. The first identifier includes the identifier of a reference signal resource.

[0197] The second identifier may be an identifier indicating a reference signal resource for a port / port group for transmitting a reference signal. The second identifier includes identifiers of one or more reference signal resources.

[0198] The power information may also include at least one of the following: first power information and second power information.

[0199] The first power information may be a power metric value of a reference port / reference port group, and the second power information may be a power offset value of other ports / other port groups.

[0200] The above power metric value and power offset value may also be represented by a power number.

[0201] In some embodiments, the phase measurement information includes phase information corresponding to at least one reference signal resource.

[0202] Wherein, the reference signal resource is used to indicate a port for transmitting a reference signal.

[0203] Exemplarily, the phase information corresponding to the reference signal resource is the phase information of the port indicated by the reference signal resource.

[0204] In some embodiments, the phase information of the port includes one of the following:

[0205] The phase metric value of the port, the phase offset value of the port, the phase number of the port.

[0206] Wherein, the phase offset value of the port is used to characterize the difference in the phase metric value between the port and the reference port; the phase number is used to indicate the corresponding phase metric value or phase offset value.

[0207] In some embodiments, the phase measurement information further includes the identifier of one or more reference signal resources in at least one reference signal resource; and / or, the phase measurement information further includes the identifier of the reference signal resource indicating the reference port or reference port group.

[0208] In one example, the power measurement information includes a third identifier, a fourth identifier, and phase information.

[0209] Wherein, the third identifier may be an identifier of a reference signal resource indicating a reference port, and the third identifier may also be determined in other ways, for example, it may be determined by a pre-defined protocol, or it may be configured by high-layer signaling. The third identifier includes the identifier of one reference signal resource.

[0210] The fourth identifier may be an identifier of a reference signal resource indicating a port for transmitting a reference signal. The fourth identifier includes the identifiers of one or more reference signal resources. At this time, the phase information may be the phase information corresponding to one or more reference signal resources in the fourth identifier.

[0211] In one example, the power measurement information may not include the above fourth identifier. In this case, the phase information may be the phase information corresponding to all reference signal resources in the configured reference signal resource set.

[0212] In some embodiments, the phase information may be a phase metric value, a phase offset value, or a phase number.

[0213] Taking the phase information as the phase offset value as an example, the phase information is represented by one or more numerical values, and the one or more numerical values correspond one by one to the ports corresponding to the reference signal resources indicated in the fourth identifier in a preset order. Alternatively, when the phase measurement information does not include the fourth identifier, the one or more numerical values correspond one by one to the ports corresponding to the reference signal resources in the reference signal resource set in a preset order. The numerical value is the difference between the phase of the corresponding port and the phase of the reference port.

[0214] Taking the phase information as the phase number as an example, the phase information is represented by one or more phase numbers, and the one or more phase numbers correspond one by one to the ports corresponding to the reference signal resources indicated in the fourth identifier in a preset order. Alternatively, when the phase measurement information does not include the fourth identifier, the one or more phase numbers correspond one by one to the ports corresponding to the reference signal resources in the reference signal resource set in a preset order. There is a mapping relationship between the phase number and the phase offset value / phase metric value. The mapping relationship can be configured in a manner predefined by the protocol. Exemplarily, as shown in Table 1 below, it is a mapping relationship table between the phase number and the phase offset value.

[0215] Table 1 Mapping Relationship Table between Phase Number and Phase Offset Value

[0216] Phase number Phase offset value 1 π / 4 2 π / 2 3 3π / 4 4 π 5 5π / 4 6 3π / 2 7 7π / 4

[0217] Among them, phase number 1 corresponds to a phase offset value of π / 4, phase number 2 corresponds to a phase offset value of π / 2, phase number 3 corresponds to a phase offset value of 3π / 4, and so on.

[0218] When the first node simultaneously sends power measurement information and phase measurement information, the measurement feedback information may respectively include two parts: power measurement information and phase measurement information. In this way, the power measurement information and the phase measurement information may feedback measurement information of different granularities or different objects under the same granularity. For example, the power measurement information and the phase measurement information may be measurement information corresponding to different reference signal resources.

[0219] In one example, such as Figure 9As shown, the power measurement information and the phase measurement information are divided into two parts in the measurement feedback information. The power measurement information includes a second identifier and power information. The phase measurement information includes a third identifier, a fourth identifier, and phase information. At this time, the reference signal resources corresponding to the power information and the phase information may not be the same, and the corresponding reference ports may also not be the same. For relevant introductions, please refer to the above description and will not be elaborated here.

[0220] The power measurement information and the phase measurement information can also be combined and sent. For example, for the same object under the same granularity, for example, the power measurement information and the phase measurement information can be the power information and the phase information corresponding to the same multiple reference signal resources, and the corresponding reference ports can also be the same ports. In this way, the signaling overhead can be further reduced.

[0221] In another example, the measurement feedback information includes power measurement information, phase measurement information, and the identifier of at least one reference signal resource. The power measurement information includes the power information corresponding to at least one reference signal resource, and the phase measurement information includes the phase information corresponding to at least one reference signal resource.

[0222] Exemplarily, as Figure 10 shown, the measurement feedback information may further include a first identifier, power information, and phase information. Among them, the first identifier may be the identifier of the reference signal resource corresponding to the reference port required for the power information and the phase information, and the power information and the phase information may be the measurement information corresponding to all the reference signal resources in the reference signal resource set. For relevant introductions, please refer to the above description and will not be elaborated here.

[0223] As an embodiment of the present disclosure, before performing the above measurement feedback, the first node may also send the configuration information of the measurement feedback. Combining Figure 4 the embodiment shown, as Figure 11 shown, the method further includes the following steps:

[0224] Step 1101: Send second measurement configuration information to the second node.

[0225] Among them, the second measurement configuration information includes a second parameter. The second parameter is used to instruct the second node to receive the power measurement information and / or the phase measurement information.

[0226] In some embodiments, when the second parameter takes the fourth value, the second parameter is used to instruct the second node to receive the power measurement information.

[0227] When the second parameter takes the fifth value, the second parameter is used to instruct the second node to receive the phase measurement information.

[0228] When the second parameter takes the sixth value, the second parameter is used to instruct the second node to receive power measurement information and phase measurement information.

[0229] Exemplarily, the first measurement configuration information may be SRS resource set configuration information, and the first parameter may be a usage indication parameter (usage), which is used to indicate the purpose of uplink measurement feedback.

[0230] In some embodiments, the second measurement configuration information further includes configuration information of a reference signal resource set. The reference signal resource set is determined based on the ports of the second node, and the configuration information of the reference signal resource set is used to configure at least one reference signal resource.

[0231] Among them, the reference signal resource is used to indicate one or more ports for transmitting reference signals, or the reference signal resource is used to indicate a port group. The port group includes multiple ports for transmitting reference signals.

[0232] Exemplarily, the second node may report port information of the ports for transmitting reference signals, and the first node determines the configuration information of the reference signal resource set based on the reported port information.

[0233] Exemplarily, the second node may report through a buffer status report (BSR), a scheduling request (SR), or UE capability information (UE capability information). The reference signal resource set may be an SRS resource set.

[0234] In one example, one reference signal resource may correspond to one port group.

[0235] For example, 1 SRS resource set may include 2 SRS resources. Each SRS resource corresponds to one port group, and the ports in the port groups corresponding to different SRS resources in the same SRS resource set are different.

[0236] Taking the port information as 2, it means that the number of ports in one port group is 2, and at the same time, the second node also reports that the total number of ports is 4. At this time, 1 SRS resource set configured by the first node for this second node may include 2 SRS resources. Each SRS resource may correspond to 1 port group, and each port group includes 2 ports. The second node may send SRS resources according to the port grouping situation. For example, the first port group includes ports port0 and port2, and the second port group includes port1 and port3. Then the second node may send one SRS resource in the SRS resource set through port0 and port2, and send the other SRS resource in the SRS resource set through port1 and port3.

[0237] In yet another example, a reference signal resource may correspond to one port.

[0238] For example, an SRS resource set may include multiple SRS resources, and each SRS resource corresponds to one port. Different SRS resources in the same SRS resource set correspond to ports of different second nodes.

[0239] Taking the port information as 3 as an example, it indicates that the number of ports to be measured is 3. One SRS resource set configured by the first node for the second node may include 3 SRS resources, and each SRS resource may correspond to 1 port. The second node may send SRS resources according to the port situation. If the ports to be measured by the second node include port0, port2, and port3, then the second node may send the corresponding SRS resources through port0, port2, and port3 respectively.

[0240] Exemplarily, in the case where the second node does not report the port information of the ports for sending reference signals, the first node may determine the configuration information of the reference signal resource set based on the port information of all ports of the second node.

[0241] For example, the first node may configure SRS resources according to the total number of ports reported by the second node. An SRS resource set may include multiple SRS resources, and each SRS resource corresponds to one port. Different SRS resources in the same SRS resource set correspond to ports of different second nodes.

[0242] As an embodiment of the present disclosure, the above configuration of measurement feedback may also be initiated by a request from the second node. Combining Figure 11 with the embodiment shown in Figure 12 as shown, before the above step 1101, the method further includes the following steps:

[0243] Step 1201, receive measurement request information from the second node.

[0244] Wherein, the measurement request information includes at least one of the following:

[0245] Measurement request enabling information; the measurement request enabling information is used to request the first node to enable the reference signal measurement process;

[0246] A first value; the first value is used to indicate the number of ports for sending reference signals, or is used to indicate the number of ports in a port group; the port group includes multiple ports for sending reference signals;

[0247] Port numbers of one or more ports; the one or more ports are ports for sending reference signals, or the one or more ports are ports in a port group;

[0248] Power measurement values of one or more ports; the one or more ports are ports for transmitting reference signals;

[0249] Power deviation values of one or more ports; the one or more ports are ports for transmitting reference signals;

[0250] Power measurement values of one or more port groups; the port group includes multiple ports for transmitting reference signals;

[0251] Power deviation values of one or more port groups; the port group includes multiple ports for transmitting reference signals;

[0252] Spacing of the ports of the second node in the first dimension and / or the second dimension in a polarization direction of the affiliated antenna array.

[0253] In one example, the second node may report measurement request enabling information and / or first port information through BSR or SR. The first port information includes at least one of the following: a first value, port numbers of one or more ports.

[0254] In yet another example, the second node may report measurement request enabling information and / or second port information through UE capability information. The second port information includes at least one of the following: a first value, port numbers of one or more ports, power measurement values of one or more ports, power deviation values of one or more ports, power measurement values of one or more port groups, power deviation values of one or more port groups, spacing of the ports of the second node in the first dimension and / or the second dimension in a polarization direction of the affiliated antenna array.

[0255] The first node may configure the SRS resource set according to the measurement request information sent by the second node, or may perform operations such as uplink resource allocation and codebook selection according to the measurement request information.

[0256] Taking the second node as an example, Figure 13 is a flowchart of a measurement feedback method provided by an embodiment of the present disclosure. As Figure 13 shown, the method includes the following steps:

[0257] Step 1301: Transmit a reference signal to the first node.

[0258] Step 1302: Receive measurement feedback information determined based on the reference signal from the first node.

[0259] Among them, the measurement feedback information includes power measurement information and / or phase measurement information.

[0260] The above technical solutions of the present disclosure can be applied to various measurement feedback scenarios, and the following will be introduced by taking downlink measurement feedback and uplink measurement feedback as examples respectively.

[0261] 1. Downlink measurement feedback.

[0262] At this time, the first node may be a terminal, and the second node may be a base station.

[0263] In some embodiments, the power measurement information includes the power information of at least one port for transmitting a reference signal.

[0264] Exemplarily, the power information of the port includes one of the following:

[0267] In some embodiments, the power measurement information includes the power information of at least one port group. The port group includes multiple ports for transmitting reference signals.

[0270] Among them, the power metric value of the port group is determined by the power metric values of each port in the port group. The power offset value of the port group is used to characterize the difference in the power metric value between the port group and the reference port group, and the power number is used to indicate the corresponding power metric value or the power offset value.

[0271] In some examples, the power measurement information further includes the port group information of at least one port group; and / or, the power measurement information further includes the port group information of the reference port group.

[0277] The second grouping step length, which is the step length in the second dimension of any port group in at least one port group in a polarization direction of the antenna array to which it belongs.

[0278] In one example, the phase measurement information includes the phase information of at least one port for transmitting a reference signal.

[0279] Exemplarily, the phase information of the port includes one of the following:
