It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Although the current beam switching method is more, interference between signals is not considered, so that a mobile phone is switched to an adjacent cell, and after another beam is adopted, the mobile phone is subjected to stronger interference, the network quality is not high, and user experience is influenced.
Based on this, the present application provides a 5G beam fast switching method, including:
step S101, receiving a measurement report;
wherein the measurement report includes: each SSB wave beam has an SINR measurement report; the report includes the parameters: signal to interference plus noise ratio. The measurement report may also be reference signal received power, RSRP, of the respective SSB beams;
step S102, calculating the network quality score of the current wave beam according to the parameters in the measurement report; and the network quality score of the beam of the adjacent target neighbor cell;
wherein, the current cell has a plurality of adjacent cells; each adjacent cell occupies a target wave beam; in order to determine which neighbor cell has a network quality suitable for handover, the mobile terminal UE needs to calculate the network quality of the beam of each neighbor cell according to the measurement report.
Step S103, judging whether to switch the current wave beam into the target wave beam according to the network quality score of the current wave beam and the network quality score of the wave beam of the adjacent target adjacent cell;
if yes, executing step S104; if not, executing step S101;
step S104, switching the current beam to the target beam.
According to the technical scheme, the current network quality score is calculated and generated according to the measurement report comprising the signal-to-interference-plus-noise ratio; and determining whether to switch to the target beam according to the network quality scores of the current beam and the target beam. In the calculation process of the network quality score, factors for improving interference noise are used, and the influence that the interference is increased after the wave beams are switched is avoided.
There are two ways to determine whether the target beam is qualified, which are described below:
in an embodiment, when determining whether to switch the current beam to the target beam according to the network quality score of the current beam and the network quality score of the beam of the adjacent target neighboring cell:
judging whether the network quality score of the target wave beam is larger than the network quality score of the current wave beam;
if so; judging that the network quality score of the target wave beam is greater than a preset threshold value;
if so, determining to switch the current beam to the target beam.
In one embodiment, when determining whether the network quality score of the target beam is greater than the network quality score of the current beam:
if yes, judging whether the network quality score of the target beam is larger than a preset maximum threshold value or not;
if so, determining to switch the current beam to the target beam.
In one embodiment, when calculating the network quality score, the network quality score may be calculated based on the weighted measurement information; wherein the measurement information includes: reference signal received power and signal to interference plus noise ratio.
To elaborate, in one embodiment, the network quality score is calculated using the following formula:
Fitness＝Wrsrp×SSB_RSRPf+Wsinr×SSB_SINRf；
wherein, Fitness is network quality score;
SSB_RSRPfreceiving power for a reference signal;
wrsrpthe weight value corresponding to the reference signal receiving power;
SSB_SINRfis the signal to interference plus noise ratio;
wsinrthe weights corresponding to the signal to interference plus noise ratio.
In one embodiment, the weighted measurement information further comprises: overlap parameter Overlap of SSB current wave beam and physical resource blockf；
Wherein, the above parameter OverlapfCan be calculated analytically from the MR measurement report.
Network quality score Fitness ═ wrsrp×SSB_RSRPf+woverlap×Overlapf +wsinr×SSB_SINRf；
Wherein, woverlapThe weight value corresponding to the parameter Overlap.
Wherein, the weight of the parameter is set according to the requirement, if the interference factor of the signal is considered, the weight wsinrThe larger the setting. Reference signal received power w if the endpoint takes into account the strength of the signalrsrpThe larger is set; if the parameter Overlap does not need to be considered, the corresponding weight woverlapMay be set to zero.
For example, can be wsinrMay be set to 0.4; w is arsrpMay be set to 0.5; w is aoverlapMay be set to 0.1;
or, mixing wsinrMay be set to 0.5; w is arsrpMay be set to 0.4; w is aoverlapMay be set to 0.1.
Because the weight is adopted, the proportion of each parameter can be flexibly adjusted; w in the present applicationsinrThe weight value of (2) can be set to be maximum; therefore, the network quality can be calculated according to the factors of signal interference; so calculatedThe quality score can reflect the interference condition between signals, so that whether switching is carried out or not can be judged more accurately, and the situation that the user experience is influenced due to larger interference after beam switching is avoided.
In an embodiment, if the result of the determination in step S103 is yes, the current beam is switched to the target beam based on a pre-established QCL (Quasi Co-Location) relationship between the time-frequency offset tracking TRS and the SSB beam.
