Abstract

A beam management method, an apparatus thereof and an intelligent beam management device. The method includes querying a database according to position information (x 0 , y 0 , z 0 ) of a terminal equipment, the database including multiple entries, each entry containing beam measurement related information of a point (x i , y i , z i ), selecting entries corresponding to points in a predetermined range of the terminal equipment from the database; selecting no more than a first number of identifiers (IDs) of base station transmitter beams with the highest number of occurrences from all the selected entries; and determining a base station transmitter beam serving the terminal equipment according to whether beams corresponding to the no more than a first number of IDs of base station transmitter beams belong to a serving base station or another base station.

Claims (66)

1. A beam management apparatus comprising:

a memory; and

processor circuitry coupled to the memory and configured to:

perform beam selection based on beam measurement related information,

wherein the beam measurement related information includes:

a value of a Reference Signal Received Power; and

a weight, wherein

the weight represents confidence of a beam measurement result; or

the weight is proportional to the number of beams searched, and

the beam measurement related information further includes part or all of the following information:

a position information;

a base station transmitter beam identifier;

whether a beam measurement result is optimal; and

a timestamp.

2. The beam management apparatus according to claim 1 , wherein,

the base station transmitter beam identifier corresponds to a beam identifier with the highest Reference Signal Received Power among one or more beams for measurement, the one or more beams being configured by a serving base station.

3. The beam management apparatus according to claim 1 , wherein

if a beam measurement for performing the beam selection is based on an exhaustive beam search, a measurement result that is reported is considered optimal.

4. The beam management apparatus according to claim 1 , wherein,

the timestamp indicates a time when the measurement result has been collected, or the timestamp includes the date and time.

5. The beam management apparatus according to claim 1 , wherein

the processor circuitry is further configured to:

query a database according to position information of a terminal equipment, the database including multiple entries, each entry recording beam measurement related information of a position, and

select entries corresponding to positions in a predetermined range area of the position of the terminal equipment from the database.

6. The beam management apparatus according to claim 5 , wherein

updating the database according to the beam selection result.

11. The beam management apparatus according to claim 7 , wherein the number of occurrences of each base station transmitter beam identifier is the sum of all weights of all entries corresponding to the base station transmitter beam identifier in all the selected entries, or the sum of numbers of all entries corresponding to the base station transmitter beam identifier in all the selected entries.

13. The beam management apparatus according to claim 1 , wherein the beam selection comprises acquiring multi-path fingerprints by performing offline training for dedicated period of time and online learning for beam adjustment, the multi-path fingerprints being multipath channel characteristics associated with locations which are obtained through a beam measurement.

14. A beam measurement apparatus configured to:

a memory; and

processor circuitry coupled to the memory and configured to:

report beam measurement related information to the network device for intelligent beam management, wherein

the beam measurement related information includes:

a value of a Reference Signal Received Power; and

a weight, wherein

the weight represents confidence of a beam measurement result; or

the weight is proportional to the number of beams searched, and

the beam measurement related information further includes part or all of the following information:

a position information;

a base station transmitter beam identifier;

whether a beam measurement result is optimal; and

a timestamp.

15. The beam measurement apparatus according to claim 14 , wherein,

the base station transmitter beam identifier corresponds to the beam identifier with the highest Reference Signal Received Power among one or more beams for measurement, the one or more beams being configured by a serving base station.

16. The beam measurement apparatus according to claim 14 , wherein if a beam measurement is based on an exhaustive beam search, the reported measurement result is considered optimal.

17. The beam measurement apparatus according to claim 14 , wherein

the processor circuitry is further configured to measure on the beams according to selected first number of base station transmitter beam identifiers.

18. The beam measurement apparatus according to claim 14 , wherein,

the timestamp indicates the time when the measurement result was collected, or

the timestamp comprises the date and time.
