technical field

Background technique

The New Radio (NR) standard in the 15th edition of the 5G international standard (R15) determines the quality of a cell operating in a multi-beam cell as follows: in any detected cell, set a threshold N, which exceeds a certain quality The threshold (Threshold) and the linear average of the beam with the best quality is the cell quality of the cell measured by the UE. If the number of beams that meet the quality conditions actually detected in the cell is K<N, that is to say, the number of beams exceeding the quality threshold is less than N, the actual K beams are used to participate in the calculation to determine the cell quality. If the UE does not detect a beam If the beam meets the quality condition, the best beam quality is used to characterize the cell quality of the cell.

This determination method is applicable to UEs in idle state (idle), inactive state (inactive) and connected state. For idle/inactive UE, only half sideband (Single Side Band, SSB) can be used to calculate Reference Signal Receiving Power (RSRP); for connected UE, SSB or channel state information reference signal ( Channel State Information-Reference Signals, CSI-RS) to calculate RSRP or reference signal receiving quality (Reference Signal Receiving Quality, RSRQ) or signal to noise ratio (Signal to Interference plus Noise Ratio, SINR), this determination method depends on the base station to information sent by the terminal.

According to the existing cell quality calculation formula or reselection mechanism, when the terminal performs reselection in idle or inactive, how to determine the cell quality of the cell in the unlicensed frequency band and how to reselection are very concerned issues.

Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1:

FIG. 1 is a flowchart of a method for determining cell quality according to an embodiment of the present invention, where the method includes:

S101: The terminal listens to the idle length of the channel of the cell in the unlicensed frequency band.

Since the terminal needs to perform LBT operation before sending data each time, it can occupy the channel for data transmission only when it detects that the idle length of the channel meets a certain threshold. Therefore, in order to effectively utilize the NR-U in the unlicensed frequency band, the terminal monitors the idle channel length of the cell in the unlicensed frequency band, and the specific process of monitoring the idle channel length of the cell is the prior art, which will not be repeated here.

Wherein, the channel idle length of the cell may be an index parameter reflecting the beam of the cell or the busy and idle conditions of the channel where the cell is located, including: received signal strength indication (Received Signal Strength Indication, RSSI) or channel occupancy (Channel Occupancy, CO).

S102: Determine the cell quality of the cell in the unlicensed frequency band according to the idle channel length of the cell and the received channel idle length threshold sent by the base station.

In order to prevent the base station from sending some reference symbols because the LBT process may not obtain the right to use the channel when sending measurement reference symbols, the base station sends the channel idle length threshold to the terminal in advance in this embodiment of the present invention. For each cell in the unlicensed frequency band, the terminal determines the cell quality of the cell in the unlicensed frequency band according to the detected idle channel length of the cell and the received channel idle length threshold sent by the base station.

In this embodiment of the present invention, the terminal determines the cell quality of the cell according to the detected idle channel length of the cell in the unlicensed frequency band and the received channel idle length threshold sent by the base station. When , the cell quality of the cell in the unlicensed frequency band can be determined by combining the busy and idle conditions of the channel where the cell is located.

Example 2:

On the basis of the above embodiment, in order to accurately determine the cell quality of the cell in the unlicensed frequency band, according to the idle channel length of the cell and the received channel idle length threshold sent by the base station, determine the cell quality of the unlicensed frequency band. Cell quality includes:

When the idle length of the detected channel is greater than the idle length threshold of the channel sent by the base station, the terminal removes the channel, and calculates the RSRP value of the channel whose idle length is not greater than the idle length threshold of the channel sent by the base station. Calculate the RSRP value of each channel to determine the cell quality of the cell in the unlicensed band.

For a cell in an unlicensed frequency band, in order to accurately determine the cell quality, in this embodiment of the present invention, for a cell in an unlicensed frequency band, the terminal listens to the idle length of the channel, specifically, the RSSI value and/or the CO value of the listening channel , and the base station may preconfigure the RSSI threshold value T _RSSI and/or the CO threshold value T _CO for the terminal for the terminal, and send the preconfigured channel idle length threshold to the terminal.

If the base station pre-configures and sends T _RSSI for the terminal, the terminal listens to the RSSI value of the channel and judges whether the RSSI value of the channel is greater than the T _RSSI , if so, remove the channel, and the channel will not participate in determining the cell the cell quality.

If the base station pre-configures and transmits T _CO for the terminal, the terminal listens to the RSSI value of the channel to determine whether the CO value of the channel is greater than the T _CO , if so, remove the channel, and the channel will not participate in determining the cell the cell quality.

If the base station pre-configures and sends T _RSSI and T _CO , the terminal listens to the RSSI value and CO value of the channel, and judges whether the RSSI value of the channel is greater than the T _RSSI and whether the CO value of the channel is greater than the T _CO , if If both are yes, the channel will be removed, and the channel will not participate in determining the cell quality of the cell.

For example, the terminal in the idle state can judge that the idle length of the channel is greater than the idle length threshold of the channel sent by the base station for each channel it hears. If so, remove the channel. If not, the idle length of the channel is not greater than the channel For the target channel of the idle length threshold, calculate the RSRP value corresponding to the target channel. Then, the cell quality of the cell can be determined according to the calculated RSRP value corresponding to each target channel. Specifically, determining the cell quality of the cell according to the RSRP value of each target channel is in the prior art, and details are not described herein again.

Example 3:

On the basis of the above embodiment, in order to accurately determine the cell quality of the cell in the unlicensed frequency band, according to the idle channel length of the cell and the received channel idle length threshold sent by the base station, determine the cell quality of the unlicensed frequency band. Cell quality includes:

The terminal identifies the number of first channels whose idle length of the channel is greater than the channel idle length threshold sent by the base station;

The terminal calculates the RSRP value of each channel, and determines the quality of the first candidate cell of the cell in the license-exempt frequency band according to the RSRP value of each channel;

The cell quality of the cell in the unlicensed frequency band is determined according to the quality of the first candidate cell, the quantity of the first channel, and the first offset of the channel that exceeds the idle length threshold of the channel sent by the base station.

For a cell in an unlicensed frequency band, in order to accurately determine the cell quality, in this embodiment of the present invention, for a cell in an unlicensed frequency band, the terminal listens to the idle length of the channel, specifically, the RSSI value and/or the CO value of the listening channel , and the base station can pre-configure the RSSI threshold value T _RSSI and/or CO threshold value T _CO for the terminal for the terminal, and the offset of the channel exceeding the idle length threshold of the channel, and the preconfigured The channel idle length threshold and the offset corresponding to the channel idle length threshold are sent to the terminal.

If the terminal receives the T _RSSI and/or T _CO of the beam sent by the base station and exceeds the first offset corresponding to the T _RSSI and/or the T _CO respectively, the terminal senses the RSSI value and/or CO of the channel After the value is determined, the number of first channels whose RSSI value is greater than T _RSSI and/or whose CO value is greater than T _CO can be identified in the channels where the detected beams that meet the quality requirements are located. Calculate the RSRP value of each channel detected, and determine the quality of the first candidate cell of the cell in the license-exempt frequency band according to the RSRP value of each channel. Specifically, determine the quality of the cell in the license-exempt frequency band according to the RSRP value of each channel. The process of the quality of the first candidate cell is in the prior art and will not be repeated here. Then, the cell quality of the cell is determined according to the quality of the first candidate cell, the quantity of the first channel, and the first offset corresponding to the first channel sent by the base station received by the terminal. The quality of the candidate cell is subtracted from the product of the first offset and the number of the first channel, and the difference obtained is used as the cell quality _NR-U . The specific formula (1) is as follows:

Cell quality _NR-U = first candidate cell quality - delta _beam *X(1)

Wherein, delta _beam represents the first offset, and X represents the number of the first channel.

In the embodiment of the present invention, determining the cell quality of the cell in the unlicensed frequency band according to the idle channel length of the cell and the received channel idle length threshold sent by the base station includes:

The terminal calculates the RSRP value of each channel, and determines the second candidate cell quality of the cell in the license-exempt frequency band according to the RSRP value of each channel;

Determine the unlicensed frequency band according to the quality of the second candidate cell, the idle channel length of the cell in the unlicensed frequency band, the channel idle length threshold sent by the base station, and the second offset of the channel exceeding the channel idle length threshold The cell quality of the cell.

After the terminal detects the RSSI value of the channel, it calculates the RSRP value of each channel, and determines the quality of the second candidate cell of the cell in the unlicensed frequency band according to the RSRP value of each channel. The process of determining the quality of the second candidate cell is an existing process. technology, which will not be repeated here.

Specifically, according to the quality of the second candidate cell, the channel idle length of the cell in the unlicensed frequency band, the channel idle length threshold sent by the base station, and the second offset of the channel exceeding the channel idle length threshold, determine When the cell quality of a cell in an unlicensed frequency band is used, the terminal can multiply the second offset by the RSSI value of the cell and then divide it by T _RSSI to obtain the first value. The quality of the second candidate cell is subtracted from the first value. value, the result obtained is the cell quality of the cell in the license-exempt frequency band, as shown in formula (2):

Cell quality _NR-U = second candidate cell quality - delta _cell *RSSI/T _RSSI (2)

Or, after hearing the CO value of the channel, the terminal can multiply the second offset by the CO value of the cell and then divide it by T _CO to obtain the second value, which is the quality of the second candidate cell minus the second value, the result obtained is the cell quality of the cell, as shown in formula (3):

Cell quality _NR-U = second candidate cell quality - delta _cell *CO/T _CO (3)

In formula (2) and formula (3), delta _cell represents the second offset.

It should be noted that the modifications of the above formulas (1) to (3) also fall within the scope of protection of the present application.

In this embodiment of the present invention, when the detected idle length of the channel is greater than the idle length threshold of the channel sent by the base station, the terminal removes the channel, and calculates that the idle length of the channel is not greater than the idle length threshold of the channel sent by the base station.

At the same time as the cell quality, the cell quality of the cell in the license-exempt frequency band is reported.

In order to facilitate the terminal to report more information about the quality of the cell to the base station, the base station sends some information to the terminal in advance for the information that the terminal needs to report. The ID of the beam with the threshold corresponding to the CO may also be the number X of the first channels whose idle length is greater than the idle length threshold sent by the base station, or may be the RSSI value and/or the CO value detected by itself.

Therefore, in order to facilitate the base station to know the quality of the cell in the unlicensed frequency band, when reporting the cell quality to the base station, the terminal may also report the identification information of the beam whose detected channel idle length exceeds the preset channel idle length threshold, or the beam The quantity information is reported to the base station.

Therefore, the terminal may receive the channel idle length threshold sent by the base station through broadcast information or RRC signaling.

Example 5:

At this time, the terminal may first calculate the detected first R value of each cell, that is, calculate the first R value of the detected serving cell and all neighboring cells. The serving cell and all neighboring cells include cells in the unlicensed frequency band and cells in the licensed frequency band.

The specific process of calculating the first R value is in the prior art, and details are not described herein again.

Example 6:

On the basis of the above embodiments, in order to more accurately determine the second R value of the cell in the unlicensed frequency band, the free channel length of the cell and the received channel idle length threshold sent by the base station are used to determine the free channel. The second R-values for cells in the licensed band include:

Then, according to the first R value corresponding to the cell, the number of the second channels, and the first offset, the second R value of the cell in the unlicensed frequency band is determined. Specifically, the first R value may be The R value is subtracted from the product of the first offset and the number of the second channel, and the difference obtained is used as the second R value R _NR-U , and the specific formula (4) is as follows:

R _NR-U = first R value - delta _beam *X(4)
