Description

Indication method for measuring frequency point, frequency point measuring method, base station and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an indication method for measuring a frequency point, a frequency point measurement method, a base station, and a terminal.
Background
In the case of frequently deploying a plurality of carriers in an existing network, such as a carrier aggregation scenario, or a scenario of jointly deploying a plurality of carriers, where the scenarios include intra-band (intra-band) multi-carrier deployment and inter-band (inter-band) multi-carrier deployment, especially in the intra-band multi-carrier deployment scenario, the carriers are now independent of each other, when a terminal performs cell selection/reselection, because each carrier belongs to one intra-band, channel propagation characteristics are relatively close, among these co-sited inband inter-cell inter-cells, in general, except for differences in carrier bandwidths or differences in configuration parameters related to bandwidths, all other configurations are almost completely the same, it can be considered that the carriers are clone cells, for the terminal, a candidate target cell is selected from a measurement result based on a cell on a certain frequency point, compared with a target cell selected from a cell measurement result based on cells on all frequency points, there is no significant difference to the user experience. However, in the existing standard, the three frequency points still need to be configured as different frequency points to the terminal, otherwise, if only one frequency point information is configured, the terminal will only measure and obtain a candidate reselection cell or a candidate target handover cell based on the frequency point configured in the system information or the neighboring cell configuration information, which results in a severe imbalance of loads on the frequency point and other frequency points. If 3 frequency points are configured, the terminal needs to measure each frequency point, but although the number of candidate reselected cells or candidate target handover cells obtained on the three frequency points is large, the situation of load imbalance is avoided, but the terminal has no practical significance for the service experience of the terminal, and larger measurement power consumption is also caused; meanwhile, if there are many frequency bands in an operator, and each frequency band has several frequency points, it may cause that part of the frequency configurations are invalid due to the limited measurement capability of the terminal, for example, the maximum 8 different frequency measurement capabilities in LTE. Or if all three frequency points are configured and the terminal is instructed to directly select one frequency point for residence according to a certain probability through the redistribution configuration information, the priority configuration information between the three frequency points and other frequency points is invalid.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides an indication method for measuring frequency points, including:
step 11, sending first indication information of a plurality of inter-related to-be-detected pilot frequency points configured for a terminal or second indication information of a plurality of inter-related to-be-detected pilot frequency point groups to the terminal, and selecting one to-be-detected pilot frequency point from the plurality of inter-related to-be-detected pilot frequency points by the terminal for measurement or selecting one to-be-detected pilot frequency point group from the plurality of inter-related to-be-detected pilot frequency point groups by the terminal for measurement; in the process, the terminal only selects the measurement frequency point, but not the resident frequency point or the resident cell, and after the terminal selects the measurement frequency point from the frequency point to be measured or the frequency point group to be measured, the terminal still needs to determine the candidate resident cell at least by combining the measurement result on the frequency point where the cell currently resident or accessed by the terminal is located and/or the priority information configured by the current cell, and/or determine the candidate handover cell by the measurement object configuration information.
The pilot frequency point group to be tested comprises at least one pilot frequency point to be tested; and the plurality of inter-related pilot frequency points to be tested do not contain the frequency point of the cell where the terminal currently resides or is accessed. It should be noted that the network node where the terminal currently resides or accesses is a cell or a base station, and is not specifically limited herein.
Wherein the first indication information includes: the method comprises the following steps of obtaining frequency point information of a plurality of pilot frequency points to be detected and first association indication information indicating that the pilot frequency points to be detected are in an association relationship with each other; the second indication information includes: the pilot frequency point groups to be detected comprise frequency point information of pilot frequency points to be detected and second association indication information indicating that the pilot frequency point groups to be detected are in an association relationship.
Preferably, in the above embodiment of the present invention, the channel propagation characteristics of the multiple inter-related pilot frequency points to be detected are similar, for example, the multiple inter-related pilot frequency points to be detected belong to the same frequency point, and the number of cells respectively corresponding to each of the multiple inter-related pilot frequency points to be detected is the same.
For example, in a 60MHz frequency on LTE Band41, corresponding to 3 20MHz carrier frequencies, 3 different frequency cells may be configured in one sector, for example, frequency point a, frequency point B, and frequency point C are set in order from low frequency to high frequency according to carrier frequency points; at this time, if there is no other cell in the same frequency band, or if one sector in the adjacent base station is configured with the three different frequency cells, it can be considered that the signal quality of the cell measured on the frequency point a can basically reflect the signal quality of the cell measured on the frequency point B or the frequency point C; therefore, when the terminal performs neighbor cell measurement in an idle cell selection or reselection or connection state, only one of the frequency points (frequency point A, frequency point B or frequency point C) needs to be selected and measured to obtain a candidate resident cell or a candidate target handover cell, and all three frequency points (frequency point A, frequency point B or frequency point C) can be measured to obtain the same user experience of the candidate resident cell or the candidate target handover cell; by the method, the number of frequency points measured by the terminal can be reduced, so that the power consumption required by the terminal measurement is reduced, and the effectiveness of the measurement can be improved under the condition that the pilot frequency measurement capability of the terminal is limited.
Preferably, in the above embodiment of the present invention, the channel propagation characteristics between the multiple inter-related sets of the pilot frequency points to be measured are also similar. Each pilot frequency point group to be tested at least comprises one pilot frequency point to be tested. Specifically, the pilot frequency point group to be detected may include one pilot frequency point to be detected, two pilot frequency points to be detected, or more pilot frequency points to be detected. After the terminal selects one pilot frequency point group to be measured, each pilot frequency point to be measured contained in the pilot frequency point group to be measured is measured respectively.
For example, in a 60MHz frequency on LTE Band41, 2 20MHz carrier frequencies and 2 10MHz carrier frequencies are corresponding, and4 different-frequency cells may be configured in one sector, for example, 20MHz frequency point a, 20MHz frequency point B, 10MHz frequency point C, and 10MHz frequency point D are set in order from low frequency to high frequency according to carrier frequency points. At this time, the frequency point A and the frequency point C form a first pilot frequency point group to be measured, the frequency point B and the frequency point D form a second pilot frequency point group to be measured, and the signal quality of the cell measured by the terminal on the first frequency point group can basically reflect the signal quality of the cell measured on the second pilot frequency point group to be measured. Therefore, when the terminal performs neighbor cell measurement in an idle cell selection or reselection or connection state, only one to-be-measured pilot frequency point group needs to be selected and measured to obtain a candidate resident cell or a candidate target handover cell; by the method, the number of frequency points measured by the terminal can be reduced, so that the power consumption required by the terminal measurement is reduced, and the effectiveness of the measurement can be improved under the condition that the pilot frequency measurement capability of the terminal is limited.
Further, step 11 in the above embodiment of the present invention includes:
step 111, sending a system message carrying first indication information of a plurality of inter-related to-be-detected pilot frequency points or second indication information of a plurality of inter-related to-be-detected pilot frequency point groups to a terminal; or
Step 112, sending idle adjacent channel measurement configuration information carrying first indication information of a plurality of inter-related pilot frequency points to be measured or second indication information of a plurality of inter-related pilot frequency point groups to be measured to the terminal; alternatively, the first and second electrodes may be,
step 113, sending connected measurement object configuration information carrying the first indication information of the multiple inter-related to-be-measured pilot frequency points or the second indication information of the multiple inter-related to-be-measured pilot frequency point groups to the terminal.
Further, in the above embodiment of the present invention, the method further includes:
step 12, sending measurement probability configuration information of the plurality of pilot frequency points to be measured which are correlated with each other or the plurality of pilot frequency point groups to be measured which are correlated with each other to a terminal; wherein the measurement probability configuration information is explicit configuration information or the measurement probability configuration information is implicit configuration information.
The display configuration information specifically refers to that the base station directly gives a measurement probability interval, the implicit configuration information specifically refers to that the base station only gives auxiliary information, and the terminal can obtain the measurement probability interval through specific rule calculation based on the auxiliary information.
Specifically, when the measurement probability configuration information is explicit configuration information, the measurement probability configuration information includes: the method comprises the following steps that a measurement probability interval of each pilot frequency point to be measured in a plurality of pilot frequency points to be measured or a measurement probability interval of each pilot frequency point group to be measured in a plurality of pilot frequency point groups to be measured;
or, when the measurement probability configuration information is implicit configuration information, the measurement probability configuration information includes: the carrier frequency width of each pilot frequency point to be detected in a plurality of pilot frequency points to be detected and the sequencing relation of the pilot frequency points to be detected; or the sum of the carrier frequency widths of the pilot frequency points to be detected contained in each pilot frequency point group to be detected in a plurality of pilot frequency point groups to be detected and the sequencing relation of the pilot frequency point groups to be detected.
For example, when the terminal reads the first indication information or the second indication information configured in the system message of the cell corresponding to the cell Ax (the cell corresponding to the frequency point a, that is, the cell on the frequency point a, is called the cell Ax), the first indication information or the second indication information may be the frequency point information of the frequency point B and the frequency point C, or the PCI information and the cell carrier frequency information of the cell Bx (the cell corresponding to the frequency point B, that is, the cell on the frequency point B, is called the cell Bx) and the cell Cx (the cell on the frequency point C, that is, the cell on the frequency point C, is called the cell Cx). Meanwhile, measurement probability configuration information related to load balancing is configured among the associated cells a, B, and C, specifically, if the loads of the configured cells a, B, and C are equivalent, the cells a/B/C respectively bear the loads of 1/3, 1/3, and 1/3, which may be specifically, for example, configured in the cell a: the measurement probability interval of the frequency point A is (0, 1/3), the measurement probability interval of the frequency point B is (1/3, 2/3) and the measurement probability interval of the frequency point C is (2/3, 1), after the terminal sees the system information of the cell Ax, the terminal can decide which frequency point of the 3 frequency points is selected as the measurement frequency point to carry out cell measurement based on the interval where the random number is generated by the terminal, and therefore candidate reselection cells and candidate target switching cells are found through measurement of the measurement cells.
In summary, in the above embodiments of the present invention, the first indication information or the second indication information configures multiple inter-related inter-frequency points to be detected or multiple inter-frequency point groups to be detected for the terminal, so that when the terminal receives the first indication information or the second indication information, the terminal can select one inter-frequency point to be detected from the multiple inter-frequency points to be detected for measurement, or select one inter-frequency point group to be detected from the multiple inter-frequency point groups to be detected for measurement; and then avoid the terminal to measure all frequency points that the base station disposes, reduce the quantity of the frequency point that the terminal measures, reduce the measurement power consumption of the terminal and increase the measuring chance of the effective measurement frequency point.
As shown in fig. 2, an embodiment of the present invention further provides a frequency point measurement method, including:
step 21, acquiring first indication information of a plurality of correlated pilot frequency points to be detected configured for the terminal by the base station or second indication information of a plurality of correlated pilot frequency point groups to be detected; wherein the first indication information includes: the method comprises the following steps of obtaining frequency point information of a plurality of pilot frequency points to be detected and first association indication information indicating that the pilot frequency points to be detected are in an association relationship with each other; the second indication information includes: the pilot frequency point groups to be detected comprise frequency point information of pilot frequency points to be detected and second association indication information indicating that the pilot frequency point groups to be detected are in an association relationship; the pilot frequency point group to be tested comprises at least one pilot frequency point to be tested;
step 22, selecting a pilot frequency point to be detected from the correlated pilot frequency points to be detected or selecting a pilot frequency point group to be detected from the correlated pilot frequency point groups to be detected;
and step 23, measuring the selected pilot frequency points to be measured or measuring the selected pilot frequency point group to be measured.
Preferably, in the above embodiment of the present invention, the channel propagation characteristics of the multiple inter-related pilot frequency points to be detected are similar, for example, the multiple inter-related pilot frequency points to be detected belong to the same frequency point, and the number of cells corresponding to each of the multiple inter-related pilot frequency points to be detected is the same.
For example, in a 60MHz frequency on LTE Band41, corresponding to 3 20MHz carrier frequencies, 3 different frequency cells may be configured in one sector, for example, frequency point a, frequency point B, and frequency point C are set in order from low frequency to high frequency according to carrier frequency points; at this time, if there is no other cell in the same frequency band, or if one sector in the adjacent base station is configured with the three different frequency cells, it can be considered that the signal quality of the cell measured on the frequency point a can basically reflect the signal quality of the cell measured on the frequency point B or the frequency point C; therefore, when the terminal performs neighbor cell measurement in an idle cell selection or reselection or connection state, only one of the frequency points (frequency point A, frequency point B or frequency point C) needs to be selected and measured to obtain a candidate resident cell or a candidate target handover cell; the method can obtain and measure all three frequency points (frequency point A, frequency point B or frequency point C) to obtain the same user experience of the candidate resident cell or the candidate target switching cell, and the number of the frequency points measured by the terminal can be reduced by the method, so that the power consumption required by the terminal measurement is reduced, and the effectiveness of the measurement can be improved under the condition that the pilot frequency measurement capability of the terminal is limited.
Preferably, in the above embodiment of the present invention, the channel propagation characteristics between the multiple inter-related sets of the pilot frequency points to be measured are also similar. Each pilot frequency point group to be tested at least comprises one pilot frequency point to be tested. Specifically, the pilot frequency point group to be detected may include one pilot frequency point to be detected, two pilot frequency points to be detected, or more pilot frequency points to be detected. After the terminal selects one pilot frequency point group to be measured, each pilot frequency point to be measured contained in the pilot frequency point group to be measured is measured respectively.
For example, in a 60MHz frequency on LTE Band41, 2 20MHz carrier frequencies and 2 10MHz carrier frequencies are corresponding, and4 different-frequency cells may be configured in one sector, for example, 20MHz frequency point a, 20MHz frequency point B, 10MHz frequency point C, and 10MHz frequency point D are set in order from low frequency to high frequency according to carrier frequency points. At this time, the frequency point A and the frequency point C form a first pilot frequency point group to be measured, the frequency point B and the frequency point D form a second pilot frequency point group to be measured, and the signal quality of the cell measured by the terminal on the first frequency point group can basically reflect the signal quality of the cell measured on the second pilot frequency point group to be measured. Therefore, when the terminal performs neighbor cell measurement in an idle cell selection or reselection or connection state, only one to-be-measured pilot frequency point group needs to be selected and measured to obtain a candidate resident cell or a candidate target handover cell; by the method, the number of frequency points measured by the terminal can be reduced, so that the power consumption required by the terminal measurement is reduced, and the effectiveness of the measurement can be improved under the condition that the pilot frequency measurement capability of the terminal is limited.
Preferably, step 23 in the above embodiment of the present invention includes:
231, performing frequency point measurement on the selected pilot frequency point to be measured; or, carrying out cell measurement on the selected cell on the pilot frequency point to be measured;
step 23 comprises:
and step 232, measuring the pilot frequency points to be measured contained in the selected pilot frequency point group to be measured.
It should be noted that one to-be-measured pilot frequency point may correspond to one cell, and may also correspond to multiple cells, which is not specifically limited herein.
Preferably, step 21 in the above embodiment of the present invention includes:
step 211, receiving a system message, where the system message carries first indication information of a plurality of inter-related pilot frequency points to be detected or second indication information of a plurality of inter-related pilot frequency point groups to be detected; alternatively, the first and second electrodes may be,
step 212, receiving idle adjacent channel measurement configuration information, where the adjacent channel measurement configuration information carries first indication information of a plurality of inter-related inter-frequency points to be detected or second indication information of a plurality of inter-frequency points to be detected; alternatively, the first and second electrodes may be,
step 213, receiving measurement object configuration information in a connected state, where the measurement object configuration information carries first indication information of multiple inter-related inter-frequency points to be measured or second indication information of multiple inter-frequency point groups to be measured.
Further, the method in the above embodiment of the present invention further includes:
and 24, acquiring measurement probability configuration information of the plurality of inter-related pilot frequency points to be measured or the plurality of inter-related pilot frequency point groups to be measured. Wherein the measurement probability configuration information is explicit configuration information or the measurement probability configuration information is implicit configuration information.
The display configuration information specifically refers to that the base station directly gives a measurement probability interval, the implicit configuration information specifically refers to that the base station only gives auxiliary information, and the terminal can obtain the measurement probability interval through specific rule calculation based on the auxiliary information.
Specifically, when the measurement probability configuration information is explicit configuration information, the measurement probability configuration information includes: the measurement probability interval of each pilot frequency point to be measured in a plurality of pilot frequency points to be measured or the measurement probability interval of each pilot frequency point group to be measured in a plurality of pilot frequency point groups to be measured.
Or, when the measurement probability configuration information is implicit configuration information, the measurement probability configuration information includes: the carrier frequency width of each pilot frequency point to be detected in a plurality of pilot frequency points to be detected and the sequencing relation of the pilot frequency points to be detected; or the carrier frequency width sum of the pilot frequency points to be detected contained in each pilot frequency point group to be detected in a plurality of pilot frequency point groups to be detected and the sequencing relation of the pilot frequency point groups to be detected;
when the measurement probability configuration information is implicit configuration information, the method further includes:
determining a measurement probability interval of each pilot frequency point to be measured in a plurality of pilot frequency points to be measured according to the carrier frequency width of each pilot frequency point to be measured in the plurality of pilot frequency points to be measured and the sequencing relation of the plurality of pilot frequency points to be measured; or determining the measurement probability interval of each to-be-measured pilot frequency point group in the plurality of to-be-measured pilot frequency point groups according to the sum of the carrier frequency widths of the to-be-measured pilot frequency points contained in each to-be-measured pilot frequency point group in the plurality of to-be-measured pilot frequency point groups and the sequencing relation of the plurality of to-be-measured pilot frequency point groups.
For example, when the terminal reads the first indication information or the second indication information configured in the system message of the cell corresponding to cell a (corresponding to frequency point a, that is, the cell on frequency point a is referred to as cell a), the first indication information or the second indication information may be the frequency point information of frequency point B and frequency point C, or the PCI information and the cell carrier frequency information of cell Bx (corresponding to frequency point B, that is, the cell on frequency point B is referred to as cell Bx) and cell Cx (corresponding to frequency point C, that is, the cell on frequency point C is referred to as cell Cx). Meanwhile, measurement probability configuration information related to load balancing is configured among the associated cells a, B, and C, specifically, if the loads of the configured cells a, B, and C are equivalent, the cells a/B/C respectively bear the loads of 1/3, 1/3, and 1/3, which may be specifically, for example, configured in the cell a: the measurement probability interval of the frequency point A is (0, 1/3), the measurement probability interval of the frequency point B is (1/3, 2/3) and the measurement probability interval of the frequency point C is (2/3, 1), after the terminal sees the system information of the cell Ax, the terminal can decide which frequency point of the 3 frequency points is selected as the measurement frequency point to carry out cell measurement based on the interval where the random number is generated by the terminal, and therefore candidate reselection cells and candidate target switching cells are found through measurement of the measurement cells.
Further, step 22 in the above embodiment of the present invention includes:
the terminal randomly generates a random number between 0 and 1;
comparing the random number with the measurement probability intervals of the plurality of pilot frequency points to be measured or the measurement probability intervals of the plurality of pilot frequency point groups to be measured which are mutually related;
selecting one pilot frequency point to be detected or one pilot frequency point group to be detected from the plurality of pilot frequency points to be detected or the plurality of pilot frequency point groups to be detected which are mutually associated according to a comparison result; and the random number falls into the measurement probability interval of the selected pilot frequency point to be measured or the selected pilot frequency point group to be measured.
For example, if the random number randomly generated by the terminal is 0.5, the terminal selects the frequency point B corresponding to the cell B to perform frequency point or cell measurement to find that the candidate reselected cell and the candidate target cell are switched.
The frequency point measuring method provided by the embodiment of the invention can reduce the number of frequency points measured by the terminal, reduce the measuring power consumption of the terminal, increase the measuring opportunity of effectively measuring the frequency points, ensure the load balance among cells on each frequency point and optimize the performance of the terminal and the base station.
In summary, in the above embodiments of the present invention, the first indication information or the second indication information configures multiple inter-related inter-frequency points to be detected or multiple inter-frequency point groups to be detected for the terminal, so that when the terminal receives the first indication information or the second indication information, the terminal can select one inter-frequency point to be detected from the multiple inter-frequency points to be detected for measurement, or select one inter-frequency point group to be detected from the multiple inter-frequency point groups to be detected for measurement; and then avoid the terminal to measure all frequency points that the base station disposes, reduce the quantity of the frequency point that the terminal measures, reduce the measurement power consumption of the terminal and increase the measuring chance of the effective measurement frequency point.
