【Detailed ways】

In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

It should be clear that the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. As used in the embodiments of this application and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise.

The current beam switching method, although there are many methods, does not take into account the interference between the signals, which will cause the mobile phone to switch to the adjacent cell. After using another beam, it will experience relatively strong interference, and the network quality is not high. , which affects the user experience.

Based on this, this application proposes a 5G beam fast switching method, including:

Step S101, receiving a measurement report;

Wherein, the measurement report includes: the SINR measurement report of each SSB beam; the report includes the parameter: signal-to-interference-plus-noise ratio. The measurement report may also be the reference signal received power RSRP of each SSB beam;

Step S102, calculating the network quality score of the current beam according to the parameters in the measurement report; and the network quality score of the beam of the adjacent target neighborhood;

Among them, the current cell has multiple adjacent cells; each adjacent cell occupies a target beam; in order to determine which adjacent cell is more suitable for handover, the mobile terminal UE needs to calculate the beam of each adjacent cell according to the measurement report. network quality.

Step S103, judging 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 adjacent target neighbor beams;

If yes, go to step S104; if no, go to step S101;

Step S104, switching the current beam to the target beam.

According to the technical scheme of the present invention, the current network quality score is calculated and generated according to the measurement report including the signal to interference plus noise ratio; whether to switch to the target beam is determined according to the network quality score of the current beam and the target beam. In the calculation process of the network quality score, the factor that improves the interference noise is used to avoid the influence of the increase of interference after beam switching.

There are two ways to judge whether the target beam is qualified or not, which are described below:

In one embodiment, when judging 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 adjacent target neighbor beam:

Judging whether the network quality score of the target beam is greater than the network quality score of the current beam;

If yes; then judge that the network quality score of the target beam is greater than a predetermined threshold;

If yes, it is determined to switch the current beam to the target beam.

In one embodiment, when judging whether the network quality score of the target beam is greater than the network quality score of the current beam:

If so, determine whether the network quality score of the target beam is equal to or greater than a predetermined maximum threshold;

If yes, it is determined 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 according to 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 following formula is used to calculate the network quality score:

Fitness=W _rsrp ×SSB_RSRP _f +W _sinr ×SSB_SINR _f ;

Among them, Fitness is the network quality score;

SSB_RSRP _f is the reference signal received power;

w _rsrp is the weight corresponding to the received power of the reference signal;

SSB_SINR _f is the signal to interference plus noise ratio;

w _sinr is the weight corresponding to the signal to interference plus noise ratio.

In an embodiment, the weighted measurement information further includes: Overlap _f , an overlap parameter between the current beam of the SSB and the physical resource block;

The above-mentioned parameter Overlap _f can be obtained by analytical calculation according to the MR measurement report.

Network quality score Fitness=w _rsrp ×SSB_RSRP _f +w _overlap ×Overlap _f +w _sinr ×SSB_SINR _f ;

Among them, w _overlap is the weight corresponding to the parameter Overlap.

Among them, the weights of the parameters are set according to the needs. If the interference factor of the signal is mainly considered, the weights w _sinr are set to be larger. If the endpoint considers the signal strength, the reference signal received power w _rsrp is set to be larger; if the parameter Overlap does not need to be considered, the corresponding weight w _overlap can be set to zero.

For example, w _sinr can be set to 0.4; w _rsrp can be set to 0.5; w _overlap can be set to 0.1;

Alternatively, w _sinr can be set to 0.5; w _rsrp can be set to 0.4; w _overlap can be set to 0.1.

Due to the use of weights, the proportion of each parameter can be flexibly adjusted; the weight of w _sinr in this application can be set to be the largest; thus, the network quality can be calculated according to the factors of signal interference; therefore, the calculated quality score is more accurate It reflects the interference between signals, which is beneficial to more accurately determine whether to switch or not, and avoids the occurrence of more interference after beam switching, which affects the user experience.

In one embodiment, if the result of the judgment in step S103 is yes, the one-to-one QCL (Quasi Co-Location, quasi co-location) relationship between the TRS and the SSB beam is tracked based on the pre-established time-frequency offset, and the current The beam is switched to the target beam.

In the figure, TRS and SSB are in one-to-one correspondence; if there are 16 SSB beams; configure 16 time-frequency offset tracking TRS; each TRS tracks one SSB beam; if it is determined to switch to one of the beams, only need Activate the ID number of the target SSB to activate the SSB; assuming that the currently occupied beam is SSB0; if switching to SSB1; then only the link of SSB1 needs to be activated, and then switching to the beam of SSB1.

Configure PDCCH/PDSCH DMRS and refined time-frequency offset tracking TRS (Tracking RS, time-frequency offset tracking) and SSB (SS/PBCHBlock) chain mapping QCL (Quasi Co-Location) required by 5G network through TCI (Transmission Configuration Indication) state , quasi-co-location) relationship, and obtain the currently effective QCL relationship.

Step S307, determining the target beam switching gain according to the network quality score;

Step S308, determine whether the above-mentioned target beam switching gain is greater than zero; if so, go to step S309, if not, go to step S304;

Step S309, taking the target beam as an alternative; calculating and judging in turn whether the switching gain of each other target switching beam is greater than zero; listing the target beam whose switching gain is greater than zero in the set of alternatives; from the set of alternatives Select the target beam corresponding to the maximum gain value as the optimal SSB switching target beam;

Step S310, activate the TCI state id corresponding to the optimal SSB beam through the MAC CE
