Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides a beam information reporting method, a base station and a terminal, aiming at the problems that the existing MU-MIMO transmission multi-user pairing algorithm is realized based on CSI feedback, has higher complexity, is not suitable for a future 5G mobile communication system and can not ensure the pairing efficiency of 5G communication users.
As shown in fig. 1, an embodiment of the present invention provides a method for reporting beam information, including:
it should be noted that, the method is applied to a base station, and when MU-MIMO transmission is performed, the base station needs to determine a paired user of a terminal, so that the base station can simultaneously send data information to the terminal and the user paired with the terminal; generally, a base station needs to issue reporting configuration information of a beam for a terminal, where the beam refers to a beam pair formed by a transmitting beam at the base station side and a receiving beam at the terminal side, and the transmitting beam and the receiving beam are corresponding, and therefore the beam pair is called a beam pair.
102, receiving report information fed back by the terminal according to the report configuration information, wherein the report information is used for determining a paired user during multi-user multiple-input multiple-output transmission for the terminal;
it should be noted that the reporting information herein mainly refers to that the terminal performs beam measurement according to the reporting configuration information to obtain beam information meeting the requirement, and it should be noted that the beam information includes one or more beams meeting the requirement. And when the base station needs to determine the paired users for the terminal, determining the paired users of the terminal according to the reported information.
Specifically, the reporting configuration information includes: reporting configuration content by a first beam and a second beam;
it should be noted that, in the embodiment of the present invention, mainly pairing users is performed, and therefore, the reported information fed back by the terminal is used for pairing the terminal, so that the first beam refers to a service beam of the terminal, and the second beam refers to a pairing beam of the terminal.
It should be noted that, when performing user pairing, the serving beam of the terminal must be reported.
Further, the reporting of the configuration content by the second beam includes: at least one of a reporting threshold of the second beam, a threshold offset of the beam, and reporting identification information whether the second beam reports.
It should be noted that, when performing user pairing, the serving beam of the terminal also needs to be reported, and therefore, the reporting identification information needs to indicate that the second beam needs to be reported; the reporting threshold of the second beam and the threshold offset of the beam can be selected not to be reported, the base station can only configure the reporting threshold of the second beam, and the terminal can directly use the reporting threshold when receiving the reporting threshold of the second beam; the base station may also only configure the threshold offset of the beam, and when receiving the threshold offset, the terminal calculates to obtain the reporting threshold of the second beam by using the threshold offset and the reporting threshold of the first beam.
It should be noted that, because the contents included in the reporting configuration information are different, the sending modes of the contents may also be different, specifically, when the reporting configuration information includes: when at least one of the reporting threshold of the first beam, the reporting threshold of the second beam, and the threshold offset of the beam, the implementation manner of step 101 is as follows: sending at least one of a reporting threshold of a first wave beam, a reporting threshold of a second wave beam and a threshold deviation of the wave beams to a terminal through Radio Resource Control (RRC) signaling; accordingly, the terminal receives the content in the corresponding reporting configuration information in the RRC signaling. When the reporting configuration information includes: when the second beam reports the identifier information, the implementation manner of step 101 is: transmitting the reporting identification information of whether the second beam is reported to the terminal through a Control Element (CE) signaling or a Downlink Control Indicator (DCI) of a Radio Resource Control (RRC) signaling, a Media Access Control (MAC) layer Control unit (CE) signaling or a physical layer Downlink Control Indicator (DCI); accordingly, the terminal receives the content in the corresponding reporting configuration information in the RRC signaling, the MAC layer CE signaling, or the DCI.
When receiving the reporting configuration information, the terminal side performs beam measurement according to the reporting configuration information to acquire reporting information; and then sending the reported information to a base station. Specifically, the implementation manner of measuring the beam and acquiring the report information by the terminal is as follows: measuring Reference Signal Received Quality (RSRQ) and/or Reference Signal Received Power (RSRP) of the wave beam according to the reported configuration information to obtain a measurement result; acquiring reported information according to the measurement result;
wherein the reporting information includes: at least one first beam information and/or at least one second beam information.
It should be noted that, the base station may also configure a reporting mode for the terminal to report information, and the specific implementation mode is as follows: a base station sends a reporting mode of reporting information to a terminal; the reporting mode comprises the following steps: at least one of a periodic reporting mode, a non-periodic trigger reporting mode and a semi-static reporting mode. Correspondingly, when receiving the reporting mode, the terminal reports the reporting information according to the reporting mode indicated by the base station.
Because the reported information may include the first beam information and the second beam information at the same time, the base station may also configure the sending modes of the first beam information and the second beam information, and the specific implementation mode is as follows: the base station sends a reporting indicator of reporting information to the terminal; the reporting indicator indicates to report the first beam information and the second beam information in a time-sharing manner or report the first beam information and the second beam information at the same time; correspondingly, when receiving the reporting indicator, the terminal transmits the first beam information and the second beam information according to the mode indicated by the base station.
It should be noted that the time-sharing reporting means: the reporting time of the first beam information is different from the reporting time of the second beam information, namely the reporting time of the first beam information is different from the reporting time of the second beam information; or the first beam information is not reported at the moment of reporting the second beam information; the simultaneous reporting means that: and the first beam information and the second beam information are reported at the same time.
It should be further noted that, when the base station determines the time information, the base station may be configured to report the time information in a time-sharing manner in a certain time period, and configured to report the time information in a simultaneous manner in another time period.
When the base station receives the report information sent by the terminal, and when the terminal adopts multi-user multiple-input multiple-output transmission based on beamforming, the base station should also determine the paired users of the terminal according to the report information. Specifically, the manner of determining the paired users is as follows: and determining the target terminal which uses the second wave beam reported by the terminal as a service wave beam for data transmission as a paired user of the terminal.
It should be noted that, when selecting a paired user for a terminal, a serving beam of the terminal needs to be determined first, and the specific manner is as follows: the base station determines a service beam for data transmission for the terminal in at least one first beam information reported by the terminal, wherein the service beam is usually a beam with a better measurement result; then, the base station determines a paired user for the terminal, where it should be noted that, according to at least one piece of second beam information reported by the terminal, the base station determines, in the second beam information, which beam is used by another terminal as a service beam, selects a second beam that can be used by another terminal as a service beam, and determines a terminal corresponding to the second beam as a paired user of the terminal. It should be noted that, when selecting a paired user for a terminal, in order to ensure that interference of data transmission is minimum, a terminal corresponding to a beam with a poor measurement result compared with a service beam of the terminal (the beam with the poor measurement result is used as a service beam of another terminal to perform data transmission) is generally selected as the paired user.
The following examples of the above embodiments of the present invention are given in the following practical applications.
For example, the gNB (shown as a base station in 5G communication) includes 8 transmission beams, the UE1, UE2, and UE3 include 1 reception beam group, and RSRP measurement of the reception beams of the UE1, UE2, and UE3 is shown in table 1:
| gNB | beam 0 | Beam 1 | Beam 2 | Beam 3 | Beam 4 | Beam 5 | Beam 6 | Beam 7 |
| UE1 | -80 | -75 | -70 | -80 | -100 | -105 | -110 | -100 |
| UE2 | -100 | -105 | -110 | -100 | -80 | -75 | -70 | -80 |
| UE3 | -80 | -75 | -70 | -80 | -100 | -105 | -110 | -100 |
TABLE 1 measurement of RSRP of UE1, UE2, UE3 receive beams
The RSRP value unit is dBm.
Assume that a first beam threshold configured by a network side (i.e., a base station) is-80 dBm, a second beam threshold is-100 dBm, and a second beam reporting identifier is activated. Based on the above configuration, the first beam information reported by the UE1 is (1, -75), (2, -70), and the second beam information is (5, -105), (6, -110); the first beam information reported by the UE2 is (5, -75), (6, -70), and the second beam information is (1, -105), (2, -110); the first beam information reported by the UE3 is (1, -75), (2, -70), and the second beam information is (5, -105), (6, -110).
Based on the reported information of the beam, the UE1 uses beamforming-based MU-MIMO transmission as an example. When receiving the first beam information and the second beam information reported by the UE1, the UE2, and the UE3, the gNB selects the beam 2 as a service beam in the first beam for data transmission; meanwhile, the gNB, when selecting the paired user for UE1, preferentially selects UE2 within the second beam for paired transmission on beam 6.
In the embodiment of the invention, the method for carrying out MU-MIMO transmission multi-user pairing based on the beam reporting information can realize multi-user pairing only by reporting the beam resource identifier and the beam measurement result by UE, avoid the computational complexity caused by realizing multi-user pairing by reporting the CQI and the PMI of the UE, and improve the multi-user pairing efficiency by the mode.
