For ease of understanding by those skilled in the art, the embodiments of the present disclosure enumerate a plurality of implementations to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will appreciate that the various embodiments provided in the embodiments of the disclosure may be implemented separately, may be implemented in combination with the methods of other embodiments of the disclosure, and may be implemented separately or in combination with some methods of other related technologies; the embodiments of the present disclosure are not so limited.

When cell switching is performed, the network needs the UE to report a measurement report including the measurement result of the radio signal. The measurement report may be event-triggered based. For example, the measurement includes a trigger that may be an "A3 event". The A3 event means that the channel quality of the neighbor cell is higher than that of the serving cell. The network is preconfigured with 1 signal measurement quality parameter to be measured by the UE in the measurement report triggered by the A3 event: reference signal received power (Reference Signal Received Power, RSRP). The measurement report reported by the UE comprises an RSRP measurement result of the serving cell and an RSRP measurement result of the neighbor cell, and the network side determines whether to perform cell switching or not based on the RSRP measurement result of the serving cell and the RSRP measurement result of the neighbor cell.

The inventors found in the study that the UE communication environment may have a better RSRP and a worse reference signal received quality (Signal Received Quality, RSRQ). Thus, the quality parameter is measured by 1 signal, namely: the RSRP judges whether to perform cell switching, and the situation that the cell performance is poor after cell switching can occur, so that the user experience is reduced. Where RSRQ is the ratio of the RSRP to the received signal strength indication (Received Singnal Strengthen Indicator, RSSI) by a factor of N to reflect the relative size between the signal and the interference. Definition of RSRQ in 3GPP standards is: signal Received Quality (RSRQ) is defined as the ratio N ×RSRP/(E-UTRA carrier RSSI), where N is the number of RB's of the E-UTRA carrier RSSI measurement bandwidth; i.e. signal reception quality (RSRQ) is defined as the ratio nxrsrp/(E-UTRA carrier RSSI), where N is the number of RBs of the E-UTRA carrier RSSI measurement bandwidth.

Therefore, how to improve the comprehensiveness of the cell performance evaluation in the cell switching process, improve the accuracy of cell switching judgment and improve the user experience is a problem to be solved urgently.

As shown in fig. 2, an embodiment of the present disclosure provides an information transmission method, which is performed by a base station, including:

Step 201: transmitting measurement configuration information associated with a cell handover event to the UE; wherein the configuration information is used for indicating at least two signal measurement quality parameters required to be measured by the UE.

The base station may be an interface device to access the network. The base station may be various types of base stations, for example, a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other base stations.

In one embodiment, the terminal may include, but is not limited to being: a mobile phone, a wearable device, a vehicle-mounted terminal, a Road Side Unit (RSU), an intelligent home terminal, an industrial sensing device and/or a medical device, etc.

The cell handover event may include: a measurement event associated with a cell handover. The cell switching event may trigger the UE to perform measurement of the radio signal and report a measurement report containing the measurement result.

By way of example, a cell switch event may include, but is not limited to, one of: the channel quality of the neighbor cell is higher than that of the serving cell; the channel quality of the neighbor cell is higher than a first channel quality threshold; the quality of the service cell channel is inferior to the second channel quality threshold; the serving cell channel quality is poor above the second channel quality threshold and the neighbor cell channel quality is above the third channel quality threshold.

In one embodiment, the cell switch event comprises: a3 measures events.

The A3 event means that the channel quality of the neighbor cell is higher than that of the serving cell.

The measurement configuration information may be used to indicate signal measurement quality parameters that the UE needs to measure at a cell handover event. And the UE performs wireless signal measurement on the signal measurement quality parameters and determines a measurement result corresponding to each signal measurement quality parameter.

The measurement results corresponding to the measurement quality parameters can be used by the base station to determine whether the cell is suitable for the UE to access.

In one possible implementation, the A3 event associated signal measurement configuration information may be used to indicate at least two signal measurement quality parameters that require the UE to measure when the channel quality of the neighboring cell is higher than the channel quality of the serving cell, the UE may perform measurement of wireless signals of the serving cell and the neighboring cell based on the at least two signal measurement quality parameters, and send measurement results to the base station, where the measurement results of the serving cell and the measurement results of the neighboring cell may be used by the base station to determine whether the neighboring cell may be used by the UE for handover.

Reference signal received quality RSRQ;

reference signal received power RSRP;

signal to interference plus noise ratio SINR.

RSRP is the power value of a cell common reference signal (such as CRS) received by a terminal, and RSRP is a linear average value of the power of a single RE in a measurement bandwidth, and reflects the strength of a cell useful signal.

RSRQ is the ratio of the RSRP to the received signal strength indicator (Received Singnal Strengthen Indicator, RSSI) by a factor of N to reflect the relative magnitude between the signal and the interference.

SINR is the ratio of the useful signal power to the sum of the interference and noise power and may reflect the quality of the received signal.

The measurement of the signal measurement quality parameter may characterize a type of channel quality. And one type of channel quality generally cannot fully reflect the actual situation of cell channel quality. For example: the RSRQ and/or SINR may be poor for the cell channel where RSRP is preferred; or the RSRP and/or SINR may be poor for the cell channel where RSRQ is preferred. Therefore, if a signal is used to measure the measurement result of the quality parameter, the channel quality of the neighboring cell cannot be estimated comprehensively, and it is inaccurate to use a signal to measure the measurement result of the quality parameter to determine whether the neighboring cell is suitable for UE access.

The base station may instruct the UE to make measurements of the quality parameters for at least two signals. And the base station determines the channel quality of the cell according to the measurement results of the quality parameters measured for at least two signals reported by the UE, so as to determine the neighbor cell for the UE to switch. Compared with the measurement result of one signal measurement quality parameter, whether the neighbor cell is suitable for UE access is judged, and the measurement results of a plurality of signal measurement quality parameters can improve the comprehensiveness and accuracy of the judgment of the channel quality of the neighbor cell.

In one possible implementation, for an A3 event, the base station may instruct the UE to measure at least two of the following signal measurement quality parameters: RSRQ; RSRP; SINR.

Illustratively, the measurement configuration information associated with the A3 event indicates that the UE is measuring at least two of RSRQ, RSRP, and SINR. Compared with the method for judging whether the neighbor cell is suitable for UE access by adopting the measurement result of one signal measurement quality parameter, the method for judging the channel quality of the neighbor cell in the A3 event can improve the comprehensiveness and the accuracy of judging the channel quality of the neighbor cell by adopting the measurement results of a plurality of signal measurement quality parameters. And the accuracy of cell switching judgment is improved.

In this way, for a cell handover event, the base station indicates at least two signal measurement quality parameters required to be measured by the UE, and compared with the determination of cell handover performed by adopting a measurement result of one signal measurement quality parameter, the measurement results of multiple signal measurement quality parameters can improve the comprehensiveness and accuracy of the determination of cell channel quality. And the accuracy of cell switching judgment is improved, and the user experience is improved.

As shown in fig. 3, an embodiment of the present disclosure provides an information transmission method, which is performed by a base station, including:

step 301: receiving a measurement report reported by the UE at least based on the measurement configuration information, wherein the measurement report at least comprises:

Step 301 may be performed alone or in combination with step 201.

When switching cells, the base station needs to compare the channel quality of the serving cell with the channel quality of the neighbor cell so as to determine whether the neighbor cell is suitable for UE access. Thus, the base station can instruct the UE to measure signal measurement quality parameters of the serving cell and the neighbor cell, respectively

The base station may instruct the UE to measure the quality parameter for each signal measurement in the serving cell, so as to obtain a first measurement result corresponding to each signal measurement quality parameter in the serving cell.

In one possible implementation, for the A3 event, the UE may measure for at least two of the RSRQ, RSRP and SINR of the serving cell, resulting in first measurement results corresponding to at least two of the RSRQ, RSRP and SINR, respectively. Of course, the above examples are illustrated using three signal measurement quality parameters, and those skilled in the art will appreciate that only one or two signal measurement quality parameters may be compared.

The base station may instruct the UE to further measure each signal measurement quality parameter of the neighboring cell, so as to obtain a second measurement result corresponding to each signal measurement quality parameter in the serving cell.

In one possible implementation, for the A3 event, the UE may measure for at least two of RSRQ, RSRP and SINR of the measured neighbor cell, resulting in second measurement results corresponding to at least two of RSRQ, RSRP and SINR, respectively. Of course, the above examples are illustrated using three signal measurement quality parameters, and those skilled in the art will appreciate that only one or two signal measurement quality parameters may be compared.

The UE may report the measurement report to the base station with the first measurement result (e.g., measurement result of at least two of the serving cell RSRQ, RSRP and SINR) and the second measurement result (e.g., measurement result of at least two of the serving cell RSRQ, RSRP and SINR) obtained by the measurement. The first measurement result and the second measurement result determine whether the neighbor cell is suitable for UE access.

In one possible implementation, the measurement report is sent by the UE in response to a third measurement result of the serving cell and a fourth measurement result of the neighboring cell meeting a preset condition, where the third measurement result and the fourth measurement result correspond to one of the at least two signal measurement quality parameters.

Here, the third measurement result may be the same as or different from the first measurement result, and the fourth measurement result may be the same as or different from the second measurement result.

The UE may monitor channel quality of the serving cell and the neighboring cell, and when the third measurement result and the fourth measurement result meet a preset condition, if the third measurement result is smaller than the fourth measurement result, that is, the channel quality of the serving cell is lower than the channel quality of the neighboring cell, determine the first measurement result and the second measurement result, and send a measurement report to the base station. The third measurement result and the fourth measurement result may be carried in the measurement report as one of the first measurement result and one of the second measurement result, respectively.

In one possible implementation, the UE may determine the measurement result of the serving cell RSRP and the measurement result of the neighbor cell RSRP, and determine the occurrence of the A3 event when the measurement result of the serving cell RSRP is worse than the measurement result of the neighbor cell RSRP. For the A3 event, the UE may determine a first measurement result of the serving cell and a second measurement result of the neighbor cell, respectively, and send the measurement report to the base station, and the base station may determine whether the neighbor cell is suitable for the UE access based on the first measurement result and the second measurement report.

As shown in fig. 4, an embodiment of the present disclosure provides an information transmission method, which is performed by a base station, including:

step 401: and determining whether the neighbor cell is a neighbor cell allowing the UE to switch or not based on a first measurement result respectively corresponding to at least two signal measurement quality parameters obtained by the UE in the serving cell and a second measurement result respectively corresponding to at least two signal measurement quality parameters obtained by the UE in the neighbor cell.

Step 401 may be implemented alone or in combination with step 201 and/or step 301.

The base station can compare the first measurement result and the second measurement result to determine the difference condition between the channel quality of the serving cell and the channel quality of the neighbor cell, and further determine whether the neighbor cell is suitable for the UE to access.

The base station can compare a first measurement result and a second measurement result of the same signal measurement quality parameter, and aims at a serving cell and a neighbor cell; the first measurement result and the second measurement result of each of the two or more signal measurement quality parameters may be compared, so as to more comprehensively evaluate the channel quality of the serving cell and the neighboring cell.

For example, the base station may compare the first measurement result corresponding to at least two of the serving cells RSRQ, RSRP and SINR with the second measurement result corresponding to at least two of the serving cells RSRQ, RSRP and SINR, i.e. the first measurement result of the serving cell RSRQ is compared with the second measurement result of the neighbor cell RSRQ, the first measurement result of the serving cell RSRP is compared with the second measurement result of the neighbor cell RSRP, and the first measurement result of the serving cell SINR is compared with the second measurement result of the neighbor cell SINR. And further, according to the comparison result, determining whether the neighbor cell is a neighbor cell allowing handover. Of course, the above examples are illustrated using three signal measurement quality parameters, and those skilled in the art will appreciate that only one or two signal measurement quality parameters may be compared.

Here, the first offset value may be a positive offset value of the second measurement result corresponding to the first signal measurement quality parameter, or may be a negative offset value of the second measurement result corresponding to the first signal measurement quality parameter. The first offset value may adjust a range of deviation between the second measurement result corresponding to the first signal measurement quality parameter and the first measurement result corresponding to the first signal measurement quality parameter.

The second offset value may be a positive offset value of the first measurement result corresponding to the second signal measurement quality parameter, or may be a negative offset value of the first measurement result corresponding to the second signal measurement quality parameter. The second offset value may adjust a range of deviation between a second measurement result corresponding to the second signal measurement quality parameter and a first measurement result corresponding to the second signal measurement quality parameter.

On the one hand, by comparing the measurement results of at least two signal measurement quality parameters, whether the neighbor cell is the neighbor cell allowing the UE to switch is determined, so that the accuracy of cell switching judgment is improved, and the user experience is improved. On the other hand, the deviation range between the second measurement result corresponding to the first signal measurement quality parameter and the first measurement result corresponding to the first signal measurement quality parameter is adjusted through the first deviation value, and the deviation range between the second measurement result corresponding to the second signal measurement quality parameter and the first measurement result corresponding to the second signal measurement quality parameter is adjusted through the second deviation value, so that the flexibility of judging whether the neighboring cell is the neighboring cell allowing the UE to switch is improved.

For example, determining the neighbor cell as a neighbor cell that allows the UE to handover may include satisfying at least two of the following conditions:

Pcell_RSRP<(Neighbor cell_RSRP+Offfset_RSRP)；

Neighbor cell_RSRQ>(Pcell_RSRQ+Offfset_RSRQ)；

Neighbor cell_SINR>(Pcell_SINR+Offfset_SINR)。

illustratively, the condition for determining the neighbor cell as the neighbor cell allowing the UE to handover may be:

Pcell_RSRP < (Neighbor cell_RSRP+Offfset_RSRP) and simultaneously satisfies at least one of the following:

Neighbor cell_RSRQ>(Pcell_RSRQ+Offfset_RSRQ)；

Neighbor cell_SINR>(Pcell_SINR+Offfset_SINR)。

wherein, pcell_rsrp represents a first measurement result of the serving cell RSRQ, neighbor_rsrp represents a second measurement result of the Neighbor cell RSRQ, and offfset_rsrp represents a first offset value; the pcell_rsrq represents a first measurement result of the serving cell RSRQ, the Neighbor cell_rsrq represents a second measurement result of the Neighbor cell RSRQ, and the offfset_rsrq represents a second offset value corresponding to the RSRQ; pcell_SINR represents a first measurement result of serving cell SINR, neighbor cell_SINR represents a second measurement result of Neighbor cell SINR, and Offset_SINR represents a second offset value corresponding to SINR;

in one possible implementation, the method further includes: and responding to the base station to determine N adjacent cells which allow switching, wherein N is a positive integer which is more than or equal to 2, and the base station determines the adjacent cells which the UE switches based on second measurement results which are respectively corresponding to the N adjacent cells which allow switching.

In the embodiment of the present disclosure, the neighbor cell that allows handover may be a neighbor cell that satisfies the foregoing handover condition.

Here, the base station may compare the first measurement result and the second measurement result between the serving cell and the plurality of neighboring cells, so as to determine neighboring cells that the plurality of UEs allow handover. The base station may select a neighbor cell with the optimal channel quality based on the second measurement result of each neighbor cell allowed to be switched, and instruct the UE to switch.

Since one neighbor cell has a plurality of second measurement results, a comparison rule may be preset herein, and the neighbor cell with the optimal channel quality is determined according to the plurality of second measurement results of the neighbor cell.

In one possible implementation, a signal measurement quality parameter for determining a neighboring cell with optimal channel quality may be predefined or agreed, and the neighboring cell with optimal channel quality may be determined by comparing a second measurement result corresponding to the signal measurement quality parameter.

In one possible implementation manner, the comparison priority of the signal measurement quality parameters may be pre-agreed, the signal measurement quality parameters with the highest priority of each cell in each collar may be compared to correspond to the second measurement result, and the neighbor cell with the optimal channel quality is determined based on the comparison result.

Corresponding to the foregoing base station side embodiment, the embodiment of the present disclosure further proposes an information transmission method performed by the user terminal UE; it should be noted that, the method corresponds to the foregoing base station side embodiment, so the same explanation or the same features are not repeated, and reference may be made to the foregoing embodiment.

As shown in fig. 5, an embodiment of the present disclosure provides an information transmission method, which is performed by a UE, including:

step 501: receiving measurement configuration information which is sent by a base station and is associated with a cell switching event; wherein the configuration information is used for indicating at least two signal measurement quality parameters required to be measured by the UE.

In one embodiment, the cell switch event comprises: a3 measures events.

reference signal received quality RSRQ;

reference signal received power RSRP;

signal to interference plus noise ratio SINR.

The base station may instruct the UE to make measurements of the quality parameters for at least two signals. The UE may determine a measurement result of each signal measurement quality parameter separately, so that the base station may determine a channel quality of the cell, and further determine a neighboring cell for handover of the UE. Compared with the measurement result of one signal measurement quality parameter, whether the neighbor cell is suitable for UE access is judged, and the measurement results of a plurality of signal measurement quality parameters can improve the comprehensiveness and accuracy of the judgment of the channel quality of the neighbor cell.

As shown in fig. 6, an embodiment of the present disclosure provides an information transmission method, which is performed by a UE, including:

step 601: transmitting a measurement report to the base station based at least on the measurement configuration information, wherein the measurement report includes at least:

Step 601 may be implemented alone or in combination with step 501.

When switching cells, the base station needs to compare the channel quality of the serving cell with the channel quality of the neighbor cell so as to determine whether the neighbor cell is suitable for UE access. Therefore, the UE needs to measure the signal measurement quality parameters of the serving cell and the neighboring cell according to the indication of the base station

The UE can measure each signal measurement quality parameter of the serving cell according to the indication of the base station to obtain a first measurement result corresponding to each signal measurement quality parameter in the serving cell.

The UE may further measure, based on the indication of the base station, a quality parameter for each signal measurement of the neighboring cell, to obtain a second measurement result corresponding to each signal measurement quality parameter in the serving cell.

In one possible implementation, for the A3 event, the UE may measure for at least two of RSRQ, RSRP and SINR of the measured neighbor cell, resulting in second measurement results corresponding to at least two of RSRQ, RSRP and SINR, respectively. Of course, the above examples are illustrated using three signal measurement quality parameters, and those skilled in the art will appreciate that only one or two signal measurement quality parameters may be compared. The UE may report the measurement report to the base station with the first measurement result (e.g., measurement result of at least two of the serving cell RSRQ, RSRP and SINR) and the second measurement result (e.g., measurement result of at least two of the serving cell RSRQ, RSRP and SINR) obtained by the measurement. The first measurement result and the second measurement result determine whether the neighbor cell is suitable for UE access.

The base station can compare a first measurement result and a second measurement result of the same signal measurement quality parameter, and aims at a serving cell and a neighbor cell; the first measurement result and the second measurement result of each of the two or more signal measurement quality parameters can be compared respectively, so that the channel quality of the serving cell and the neighbor cell can be more comprehensively evaluated.

Pcell_RSRP<(Neighbor cell_RSRP+Offfset_RSRP)；

Neighbor cell_RSRQ>(Pcell_RSRQ+Offfset_RSRQ)；

Neighbor cell_SINR>(Pcell_SINR+Offfset_SINR)。

Neighbor cell_RSRQ>(Pcell_RSRQ+Offfset_RSRQ)；

Neighbor cell_SINR>(Pcell_SINR+Offfset_SINR)。

To further explain any embodiments of the present disclosure, a specific embodiment is provided below.

As shown in fig. 7, for the A3 event, specific steps of the UE performing cell handover include:

step 701: and adding RSRQ and SINR measurement in the reconfiguration measurement of the A3 event by network equipment such as a base station and the like.

Step 702: the UE reports Measurement Report (MR) to the network containing the measurement results of RSRP, RSRQ and SINR.

Step 703: the network side determines the neighbor cells allowing the UE to switch according to the following judging criteria: pcell_RSRP < (Neighbor cell_RSRP+Offfset_RSRP) and simultaneously satisfies at least one of the following:

Neighbor cell_RSRQ>(Pcell_RSRQ+Offfset_RSRQ)；

Neighbor cell_SINR>(Pcell_SINR+Offfset_SINR)。

The network side equipment judges whether the switching standard is met or not according to the RSRP, the RSRQ and the SINR at the same time, and selects an optimal cell.

Step 704: the UE switches according to the indication of the network side equipment and resides in the optimal cell.
