A method and apparatus for measuring a beam, a user equipment, a network device and a storage medium provided by embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
In the step 101, configuration information sent by a base station is received.
In an embodiment of the present disclosure, the UE may refer to a device that provides speech and/or data connectivity for the user. The UE may communicate with one or more core networks via a Radio Access Network (RAN). The UE may be an Internet of Things terminal, such as a sensor device, a mobile phone (or a “cellular” phone), and a computer having an Internet of Things terminal, for example, a fixed, portable, pocket-sized, handheld, computer built-in or vehicle-mounted device. For example, it may be a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, or a user agent. Alternatively, the UE may also be a device of an unmanned aerial vehicle. Alternatively, the UE may also be an in-vehicle device, for example, a trip computer with a wireless communication function, or a wireless terminal external to the trip computer. Alternatively, the UE may also be a roadside device, for example, a street light, a signal light, or other roadside device with a wireless communication function, etc.
In an embodiment of the present disclosure, the configuration information may include at least one of a time-frequency resource position of at least one reference signal for the beam measurement, a first target value of a beam quality, a second target value of the beam quality, a class value of a specified anchor reference signal, a reporting condition of the beam measurement, or a measurement quantity of the beam measurement sent by the base station.
In an embodiment of the present disclosure, the method of sending the configuration information may be:
In addition, it should be noted that in an embodiment of the present disclosure, the configuration information may also be determined by the UE based on a protocol agreement. Specifically, if the UE is in the idle state or the initial access state, the UE may determine the configuration information based on the protocol agreement.
In the step 102, at least one reference signal sent by the base station is obtained based on the configuration information, a class value corresponding to the received at least one reference signal is determined, and beam measurement is performed for the at least one reference signal to obtain a measurement result.
Specifically, in an embodiment of the present disclosure, the at least one reference signal sent by the base station may be obtained based on the time-frequency resource position of the at least one reference signal in the configuration information.
It should be noted that in an embodiment of the present disclosure, the class value corresponding to the reference signal may be positively correlated with a beam bandwidth of the reference signal. That is, a beam of a reference signal with a smaller class value is narrower than a beam of a reference signal with a larger class value.
In another embodiment of the present disclosure, the class value corresponding to the reference signal may be negatively correlated with the beam bandwidth of the reference signal. That is, the beam of the reference signal with the smaller class value is wider than the beam of the reference signal with the larger class value.
In an embodiment of the present disclosure, a correspondence between the class value and the beam bandwidth may be agreed by a protocol.
Further, in an embodiment of the present disclosure, the method for the UE to determine the class value corresponding to the received at least one reference signal may include:
In an embodiment of the present disclosure, reference signals of different classes correspond to different time domain resource positions.
Further, in an embodiment of the present disclosure, the measurement quantity of the beam measurement may include at least one of:
In the step 103, a class value of an anchor reference signal is determined based on the measurement result of the reference signal and/or the configuration information, and the beam measurement and/or data reporting are performed by anchoring on an anchor reference signal corresponding to the class value of the anchor reference signal.
Specifically, in an embodiment of the present disclosure, when the class value of the anchor reference signal is determined based on the measurement result and/or the configuration information, a class value of a reference signal with a wider beam is preferably determined as the class value of the anchor reference signal on the premise of ensuring the beam quality. Therefore, when the beam measurement and/or the data reporting is subsequently performed for the anchor reference signal, not only the measurement quality of the beam can be ensured, but also a movable range of the UE is larger due to the wider beam bandwidth (that is, the larger coverage) corresponding to the anchor reference signal, further ensuring a service quality when the UE is in a moving state.
A specific method for determining the class value of the anchor reference signal in this embodiment will be introduced in detail in subsequent embodiments.
In an embodiment of the present disclosure, the method of performing the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal may include: based on the reporting condition of the beam measurement, performing, the beam measurement and/or the data reporting on a beam of the anchor reference signal, to the base station.
In an embodiment of the present disclosure, when the data reporting is performed to the base station on the beam of the anchor reference signal based on the reporting condition of the beam measurement, at least one of the following data may be reported:
a time domain resource position indication corresponding to the anchor reference signal; or
In an embodiment of the present disclosure, only data that meets the reporting condition of the beam measurement may be reported to the base station.
To sum up, in the method for measuring the beam provided by embodiments of the present disclosure, the UE may obtain the configuration information sent by the base station, and may obtain, based on the configuration information, the at least one reference signal sent by the base station, determine the class value corresponding to the received at least one reference signal, and perform the beam measurement for the at least one reference signal to obtain the measurement result. The class value is positively or negatively correlated with the beam bandwidth of the reference signal. Thereafter, the UE may determine, based on the measurement result of the reference signal and/or the configuration information, the class value of the anchor reference signal, and perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal. Therefore, in embodiments of the present disclosure, the UE may determine the class value of the anchor reference signal based on its measurement result for the at least one reference signal sent by the base station and/or the configuration information sent by the base station, and may subsequently perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal. The embodiments of the present disclosure provide the method for measuring the beam applied to the millimeter wave communication process and/or the terahertz communication process.
In the step 201, configuration information sent by a base station is obtained, and the configuration information includes a first target value of a beam quality and a second target value of the beam quality sent by the base station.
In an embodiment of the present disclosure, the first target value of the beam quality and the second target value of the beam quality may be preset, and the first target value of the beam quality may be smaller than the second target value of the beam quality. Further, for other relevant introductions about the configuration information, reference may be made to the description of the above embodiments, which will not be described in details here in the present disclosure.
In the step 202, at least one reference signal sent by the base station is obtained based on the configuration information, a class value corresponding to the received at least one reference signal is determined, and beam measurement is performed for the at least one reference signal to obtain a measurement result, the class value is negatively correlated with a beam bandwidth of the reference signal.
For the detailed introduction about the step 202, reference may be made to the description of the above embodiments, which is not described in details here in embodiments of the present disclosure.
In the step 203, a class value of an anchor reference signal is determined based on a magnitude relationship between measurement results of reference signals of different classes and the first target value of the beam quality and the second target value of the beam quality, and the beam measurement and/or data reporting are performed by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal.
In an embodiment of the present disclosure, the method of determining the class value of the anchor reference signal based on the magnitude relationship between the measurement results of the reference signals of different classes and the first target value of the beam quality and the second target value of the beam quality can include the following criterions.
Criterion 1: if there is a first reference signal among all reference signals whose measurement result is greater than or equal to the first target value of the beam quality and smaller than the second target value of the beam quality, a class value of the first reference signal is selected as the class value of the anchor reference signal. The first reference signal may include one or more reference signals.
Specifically, when the measurement result of the first reference signal is greater than the first target value of the beam quality and smaller than the second target value of the beam quality, it indicates that a beam quality corresponding to the first reference signal is better. On this basis, in an embodiment of the present disclosure, the class value of the first reference signal with the better beam quality may be directly selected as the class value of the anchor reference signal. In this case, when the beam measurement and/or the data reporting is subsequently performed on the anchor reference signal corresponding to the class value of the anchor reference signal, the beam measurement quality can be ensured.
In another embodiment of the present disclosure, the smallest class value in the first reference signal with the better beam quality may be selected as the class value of the anchor reference signal. Since the class value is negatively correlated with the beam bandwidth, a beam of a reference signal corresponding to the smallest class value in the first reference signal is the widest, that is, the beam quality corresponding to the anchor reference signal is better and the beam bandwidth corresponding to the anchor reference signal is wider. Therefore, when the beam measurements and/or the data reporting are subsequently performed on the beam of the anchor reference signal based on the class value of the anchor reference signal, not only the measurement quality of the beam can be ensured, but also the service quality when the UE is in the moving state can be ensured.
For example, in an embodiment of the present disclosure, the UE obtains a reference signal 1, a reference signal 2 and a reference signal 3 sent by the base station, the reference signal 1 corresponds to a class value of 1, the reference signal 2 corresponds to a class value of 2, and the reference signal 3 corresponds to a class value of 3. A measurement result corresponding to the reference signal 1 is smaller than the first target value of the beam quality, and measurement results corresponding to the reference signal 2 and the reference signal 3 are greater than the first target value of the beam quality and smaller than the second target value of the beam quality. In this case, class values 3 and 2 may be determined as the class value of the anchor reference signal, or only the class value of 2 may be determined as the class value of the anchor reference signal.
Criterion 2: if a measurement result of a reference signal with the largest class value is smaller than the first target value of the beam quality, a first operation is performed, and the first operation includes at least one of selecting the largest class value in all the reference signals as the class value of the anchor reference signal, performing cell reselection, or sending a handover request to the base station.
It should be noted that in an embodiment of the present disclosure, since the class value of the reference signal is negatively correlated with the beam bandwidth in this embodiment, the larger the class value of the reference signal, the narrower the beam bandwidth of the reference signal. It should be appreciated that the beam bandwidth is negatively correlated with the beam quality, that is, a beam quality of a beam with a narrower bandwidth is greater than a beam quality of a beam with a wider bandwidth, and the beam bandwidth is positively correlated with the service quality when the UE is in the moving state, that is, the wider the bandwidth of the beam, the larger the coverage of the beam, the better mobility of the UE that can be supported.
In this case, if the measurement result of the reference signal with the largest class value is smaller than the first target value of the beam quality, it indicates that measurement results of all the reference signals are smaller than the first target value of the beam quality, that is, beam qualities of all the reference signals are poor. On this basis, in an embodiment of the present disclosure, the UE may select the largest class value in the reference signals as the class value of the anchor reference signal, that is, when the beam qualities of all the reference signals are poor, the class value of the reference signal with the relatively best beam quality among the reference signals with the poor beam qualities is determined as the class value of the anchor reference signal, so as to ensure that when the beam measurement and/or the data reporting are subsequently performed on the anchor reference signal, the measurement quality of the beam can be ensured. In another embodiment of the present disclosure, the UE may also not determine the class value of the anchor reference signal, but directly perform the cell reselection and/or send the handover request to the base station in order to re-obtain a reference signal with a better beam quality.
Criterion 3: if a measurement result of a reference signal with the smallest class value is greater than or equal to the second target value of the beam quality, the smallest class value in all the reference signals is selected as the class value of the anchor reference signal.
Specifically, in an embodiment of the present disclosure, based on the foregoing description, it can be known that in the case of “the class value of the reference signal being negatively correlated with the beam bandwidth”, if the measurement result of the reference signal with the smallest class value is greater than or equal to the second target value of the beam quality, it indicates that the measurement results of all the reference signals are greater than or equal to the second target value of the beam quality, that is, the beam qualities of all the reference signals are good. In this case, in an embodiment of the present disclosure, the UE may select the minimum class value in all the reference signals as the class value of the anchor reference signal, that is, when the beam qualities of all the reference signals are good, a class value of a reference signal with the widest beam bandwidth is preferably determined as the class value of the anchor reference signal. Therefore, when the beam measurement and/or the data reporting are subsequently performed on the anchor reference signal corresponding to the class value of the anchor reference signal, the measurement quality of the beam can be ensured, and the service quality when the UE is in the moving state can be ensured.
In addition, for other introductions about the step 203, reference may be made to the description of the above embodiments, which will not be described in details here in embodiments of the present disclosure.
Furthermore, this embodiment only takes “the class value corresponding to the reference signal being negatively correlated with the beam bandwidth” as an example for illustration. In another embodiment of the present disclosure, the class value corresponding to the reference signal may also be positively correlated with the beam bandwidth. When the class value is positively correlated with the beam bandwidth of the reference signal, the method of determining the class value of the anchor reference signal based on the magnitude relationship between the measurement results of the reference signals of different classes and the first target value of the beam quality and the second target value of the beam quality may include:
Specifically, determination criterions for the class value of the anchor reference signal in a case where “the class value corresponding to the reference signal is positively correlated with the beam bandwidth” are the same as those in a case where “the class value corresponding to the reference signal is negatively correlated with the beam bandwidth”, which are both that on the premise of ensuring the beam quality, the service quality when the UE is in the moving state is further ensured, which will not be described in details here in embodiments of the present disclosure.
To sum up, in the method for measuring the beam provided by embodiments of the present disclosure, the UE may obtain the configuration information sent by the base station, and may obtain, based on the configuration information, the at least one reference signal sent by the base station, determine the class value corresponding to the received at least one reference signal, and perform the beam measurement for the at least one reference signal to obtain the measurement result. The class value is positively or negatively correlated with the beam bandwidth of the reference signal. Thereafter, the UE may determine, based on the measurement result of the reference signal and/or the configuration information, the class value of the anchor reference signal, and perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal. Therefore, in embodiments of the present disclosure, the UE may determine the class value of the anchor reference signal based on its measurement result for the at least one reference signal sent by the base station and/or the configuration information sent by the base station, and may subsequently perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal. The embodiments of the present disclosure provide the method for measuring the beam applied to the millimeter wave communication process and/or the terahertz communication process.
In the step 301, configuration information sent by a base station is obtained, and the configuration information includes a class value of an anchor reference signal specified by the base station.
In an embodiment of the present disclosure, the class value of the specified anchor reference signal may be determined by the base station.
In the step 302, at least one reference signal sent by the base station is obtained based on a time-frequency resource position of the at least one reference signal, a class value corresponding to the received at least one reference signal is determined, and beam measurement is performed for the at least one reference signal to obtain a measurement result.
In the step 303, the class value of the specified anchor reference signal is selected as a class value of an anchor reference signal, and the beam measurement and/or data reporting are performed by anchoring on an anchor reference signal corresponding to the class value of the anchor reference signal.
For example, in an embodiment of the present disclosure, assuming that the class value of the specified anchor reference signal is a class value of 3, the UE obtains the reference signal 1, the reference signal 2 and the reference signal 3, the reference signal 1 corresponds to the class value of 1, the reference signal 2 corresponds to the class value of 2, and the reference signal 3 corresponds to the class value of 3. In this case, the beam measurement and/or the data reporting may be performed directly on the reference signal 3.
In addition, for the detailed introduction about the steps 301 to 303, reference may be made to the description of the above embodiments, which is not described in details here in embodiments of the present disclosure.
To sum up, in the method for measuring the beam provided by embodiments of the present disclosure, the UE may obtain the configuration information sent by the base station, and may obtain, based on the configuration information, the at least one reference signal sent by the base station, determine the class value corresponding to the received at least one reference signal, and perform the beam measurement for the at least one reference signal to obtain the measurement result. The class value is positively or negatively correlated with the beam bandwidth of the reference signal. Thereafter, the UE may determine, based on the measurement result of the reference signal and/or the configuration information, the class value of the anchor reference signal, and perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal. Therefore, in embodiments of the present disclosure, the UE may determine the class value of the anchor reference signal based on its measurement result for the at least one reference signal sent by the base station and/or the configuration information sent by the base station, and may subsequently perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal. The embodiments of the present disclosure provide the method for measuring the beam applied to the millimeter wave communication process and/or the terahertz communication process.
In the step 401, configuration information sent by a base station is obtained.
In an embodiment of the present disclosure, the configuration information includes at least one of a time-frequency resource position of at least one reference signal for the beam measurement, a first target value of a beam quality, a second target value of the beam quality, a class value of a specified anchor reference signal, a reporting condition of the beam measurement, or a measurement quantity of the beam measurement sent by the base station.
In the step 402, at least one reference signal sent by the base station is obtained based on a time-frequency resource position of the at least one reference signal, a class value corresponding to the received at least one reference signal is determined, and beam measurement is performed for the at least one reference signal to obtain a measurement result, the class value is negatively correlated with a beam bandwidth of the reference signal.
In the step 403, a class value of an anchor reference signal is determined based on a measurement result of the reference signal and/or the configuration information, and the beam measurement and/or data reporting are performed by anchoring on an anchor reference signal corresponding to the class value of the anchor reference signal.
For the detailed introduction about the steps 401 to 403, reference may be made to the description of the above embodiments, which is not described in details here in embodiments of the present disclosure.
In the step 404, the class value of the anchor reference signal is updated according to a measurement result of the anchor reference signal, and the beam measurement and/or the data reporting are performed by anchoring on an updated anchor reference signal corresponding to the updated class value of the anchor reference signal.
In an embodiment of the present disclosure, after the anchor reference signal is determined, the beam quality of the anchor reference signal may change due to some reasons (such as the movement of the UE). In this case, it is necessary to update the anchor reference signal according to the measurement result of the anchor reference signal.
In an embodiment of the present disclosure, the method of updating the class value of the anchor reference signal according to the measurement result of the anchor reference signal may include:
Specifically, in an embodiment of the present disclosure, if the measurement result of the anchor reference signal is greater than or equal to the second target value of the beam quality, the class value of the anchor reference signal is updated, and the class value of the anchor reference signal after the update is smaller than the class value of the anchor reference signal before the update. If the measurement result of the anchor reference signal is smaller than the first target value of the beam quality, the class value of the anchor reference signal is updated, and the class value of the anchor reference signal after the update is greater than the class value of the anchor reference signal before the update.
It should be noted that in an embodiment of the present disclosure, when the measurement result of the anchor reference signal is greater than or equal to the second target value of the beam quality, it indicates that the beam qualities of all the current reference signals are better than before. In this case, the anchor reference signal may be updated to a reference signal with a smaller class value, that is, the class value of the anchor reference signal after the update is smaller than the class value of the anchor reference signal before the update. Then, based on the class value of the reference signal being negatively correlated with the beam bandwidth, the beam bandwidth of the anchor reference signal after the update is greater than the beam bandwidth of the anchor reference signal before the update. When the beam measurement and/or the data reporting are subsequently performed on the updated anchor reference signal, the service quality when the UE is in the moving state can be further ensured.
Further, in an embodiment of the present disclosure, when the measurement result of the anchor reference signal is smaller than the first target value of the beam quality, it indicates that the beam qualities of all the current reference signals are worse than before. In this case, since the beam quality of the reference signal with the narrower beam bandwidth is greater than the beam quality of the reference signal with the wider beam bandwidth, the anchor reference signal may be updated to a reference signal with a larger class value, that is, the class value of the anchor reference signal after the update is greater than the class value of the anchor reference signal before the update. Based on the class value of the reference signal being negatively correlated with the beam bandwidth, the beam bandwidth of the anchor reference signal after the update is smaller than the beam bandwidth of the anchor reference signal before the update, that is, the beam quality of the anchor reference signal after the update is higher than the beam quality of the anchor reference signal before the update. When the beam measurement and/or the data reporting are subsequently performed on the updated anchor reference signal, the measurement quality of the beam can be ensured.
For example, in an embodiment of the present disclosure, it is assumed that the UE obtains the reference signal 1, the reference signal 2, and the reference signal 3 sent by the base station, the class value of the reference signal 1 is 1, the class value of the reference signal 2 is 2, the class value of the reference signal 3 is 3, and the anchor reference signal is the reference signal 2. If it is detected that the anchor reference signal is greater than or equal to the second target value of the beam quality, the reference signal 1 may be determined as the updated anchor reference signal. If it is detected that the anchor reference signal is smaller than the first target value of the beam quality, the reference signal 3 may be determined as the updated anchor reference signal.
In addition, in an embodiment of the present disclosure, the method of performing the data reporting by anchoring on the anchor reference signal corresponding to the updated class value of the anchor reference signal may include:
In an embodiment of the present disclosure, only data that meets the reporting condition of the beam measurement may be reported to the base station.
In addition, it should be noted that this embodiment only takes “the class value corresponding to the reference signal being negatively correlated with the beam bandwidth” as an example for illustration. In another embodiment of the present disclosure, the class value corresponding to the reference signal may also be positively correlated with the beam bandwidth. When the class value is positively correlated with the beam bandwidth of the reference signal, the method of updating the anchor reference signal based on the magnitude relationship between the measurement result of the anchor reference signal and the first target value of the beam quality and the second target value of the beam quality may include:
Specifically, update criterions for the class value of the anchor reference signal in a case where “the class value corresponding to the reference signal is positively correlated with the beam bandwidth” are similar to update criterions in a case where “the class value corresponding to the reference signal is negatively correlated with the beam bandwidth”, which are both that on the premise of ensuring the beam quality, the service quality when the UE is in the moving state is further ensured, which is not described in details here in embodiments of the present disclosure.
To sum up, in the method for measuring the beam provided by embodiments of the present disclosure, the UE may obtain the configuration information sent by the base station, and may obtain, based on the configuration information, the at least one reference signal sent by the base station, determine the class value corresponding to the received at least one reference signal, and perform the beam measurement for the at least one reference signal to obtain the measurement result. The class value is positively or negatively correlated with the beam bandwidth of the reference signal. Thereafter, the UE may determine, based on the measurement result of the reference signal and/or the configuration information, the class value of the anchor reference signal, and perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal. Therefore, in embodiments of the present disclosure, the UE may determine the class value of the anchor reference signal based on its measurement result for the at least one reference signal sent by the base station and/or the configuration information sent by the base station, and may subsequently perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal. The embodiments of the present disclosure provide the method for measuring the beam applied to the millimeter wave communication process and/or the terahertz communication process.

Further, in an embodiment of the present disclosure, the measurement quantity of the beam measurement includes at least one of:
In addition, in an embodiment of the present disclosure, the method for the base station to send the configuration information to the UE may include:
Moreover, in an embodiment of the present disclosure, before sending the configuration information, the base station may also first determine a time-frequency resource position of the reference signal used for the beam measurement. In an embodiment of the present disclosure, determining the time-frequency resource position of the reference signal for the beam measurement may include the following steps:
In the step 502, at least one reference signal is sent.
In an embodiment of the present disclosure, the base station may send the at least one reference signal to the UE based on the time domain resource position determined in the step 501. The at least one reference signal has a corresponding class value, and the class value is positively or negatively correlated with the beam bandwidth of the reference signal.
In the step 503, data reported by the UE is obtained on an anchor reference signal corresponding to a class value of a reference signal anchored by the UE.
In an embodiment of the present disclosure, the method of obtaining the data reported by the UE includes at least one of:

Thereafter, the UE may determine, based on the measurement result of the reference signal and/or the configuration information, the class value of the anchor reference signal, and perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal. Therefore, in embodiments of the present disclosure, the UE may determine the class value of the anchor reference signal based on its measurement result for the at least one reference signal sent by the base station and/or the configuration information sent by the base station, and may subsequently perform the beam measurement and/or the data reporting by anchoring on the anchor reference signal corresponding to the class value of the anchor reference signal.
