Description

Method for reporting channel quality information
Technical Field
The invention relates to the technical field of mobile communication, in particular to a channel quality information reporting method.
Background
With the rapid development of global mobile broadband communication and the dramatic increase of mobile data traffic, the demand of frequency as a basic resource for the development of mobile communication is increasing, and the current frequency division cannot meet the development of future mobile communication. Under the environment of increasingly scarce spectrum resources, a broadband communication system for realizing the discrete comb spectrum is produced on the premise of not changing the original frequency point allocation based on the discrete narrowband carrier aggregation technology.
In a novel wireless broadband communication system supporting discrete narrowband carrier aggregation, a channel in a specific frequency band (for example, 223-235MHz frequency band) and in a unit of narrowband spectrum resources (for example, 25kHz) is called a carrier. The base station (hereinafter referred to as a new base station) in the new wireless broadband communication system supports full bandwidth, and the terminal (hereinafter referred to as a new terminal) in the new wireless broadband communication system generally supports single or partial carrier due to its own capability and service characteristics.
Because the novel terminal only supports the measurement of Channel Quality Indicator (CQI) on currently used carrier resources, all carriers in a full frequency band cannot be measured, and the interference condition of other carrier resources cannot be known, which is not favorable for dynamic scheduling and interference avoidance of the novel base station. For realizing full frequency band carrier measurement, novel basic station can change the work carrier position and the quantity at novel terminal dynamically, but this kind of mode needs novel basic station frequently to instruct novel terminal change work carrier position and quantity, is unfavorable for the rational use of resource.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
In the novel wireless broadband communication system supporting discrete narrowband carrier aggregation, the novel terminal only supports the quality measurement of currently used carrier resources, cannot measure all carriers of a full frequency band, cannot acquire the interference condition of other carrier resources, and is not beneficial to dynamic scheduling and interference avoidance of a novel base station. In view of the above, an embodiment of the present invention provides a method for reporting channel quality information. Fig. 1 is a schematic flow chart of a method for reporting channel quality information according to an embodiment of the present invention, and as shown in fig. 1, an execution subject of the method is a terminal in the system, where the method includes:
step 110, measuring the channel quality data of the working carrier.
Specifically, the working carrier refers to a carrier supported by the terminal, that is, a carrier used by the terminal for data interaction with the base station. The channel quality data of the active carrier may be a CQI value, an SINR (Signal to Interference plus Noise Ratio), and the like, which is not specifically limited in the embodiment of the present invention.
And step 120, if the channel quality data of the working carrier meets the measurement starting judgment condition of the non-working carrier, measuring the channel quality data of the non-working carrier in the non-service transmission time period.
Specifically, after the channel quality data of the working carrier is obtained, whether the channel quality data of the working carrier meets the non-working carrier measurement starting judgment condition is judged. Here, the non-operating carrier measurement start judgment condition may be preset by the base station and transmitted to the terminal, or may be preset by the terminal, and the non-operating carrier measurement start judgment condition represents a condition for starting channel quality measurement of the non-operating carrier. Here, the non-operating carrier is relative to the operating carrier, and all or part of the rest carriers except the operating carrier in the novel wireless broadband communication system are removed.
If the channel quality data of the working carrier meets the starting judgment condition of the non-working carrier measurement, when the terminal is in a non-service transmission period, namely when the terminal has no service transmission, the carrier is adjusted to the non-working carrier, and the channel quality data of the non-working carrier is measured; and if the channel quality data of the working carrier does not meet the measurement starting judgment condition, the channel quality data of the non-working carrier is not measured no matter whether the terminal is in the non-service transmission time interval or not.
Step 130, reporting the channel quality data of the non-working carrier to the base station.
Specifically, the channel quality data of the non-working carrier may be reported to the base station immediately after the channel quality data of the non-working carrier is obtained through measurement, or the channel quality data of the non-working carrier may be reported to the base station according to a preset reporting period, or the channel quality data of the non-working carrier may be reported to the base station when a reporting instruction issued by the base station is received, or a preset reporting condition is met, which is not specifically limited in the embodiment of the present invention.
According to the method provided by the embodiment of the invention, when the channel quality data of the working carrier meets the measurement starting judgment condition of the non-working carrier, the channel quality data of the non-working carrier is measured and reported to the base station in the non-service transmission period, so that the base station can acquire the interference condition of other carrier resources, and dynamic scheduling and interference avoidance can be better performed. And the terminal executes the measurement of the channel quality data of the non-working carrier under the trigger of the non-working carrier measurement starting judgment condition, and the base station does not need to frequently instruct the terminal to change the position and the number of the working carriers to measure the non-working carriers, thereby realizing the reasonable configuration of resources.
Based on the foregoing embodiment, in the method, step 120 specifically includes: and if the CQI value in the channel quality data of the working carrier is lower than a preset measurement starting threshold value, determining that the channel quality data of the working carrier meets the measurement starting judgment condition of the non-working carrier, and measuring the channel quality data of the non-working carrier in the non-service transmission period.
Specifically, the measured channel quality data of the working carrier includes a CQI value of the working carrier, and correspondingly, the preset starting judgment condition is that the CQI value of the working carrier is lower than a preset measurement starting threshold. The preset measurement start threshold is the preset maximum value of the working carrier CQI triggering the measurement of the channel quality data of the non-working carrier.
If the CQI value of the working carrier is lower than a preset measurement starting threshold, the CQI value of the working carrier indicates that the channel quality of the working carrier at the current moment is poor, and the working carrier adjustment is possibly needed, and the working carrier adjustment is carried out on the premise that the channel quality of a carrier which can be adjusted, namely a non-working carrier, is known, at the moment, the non-working carrier measurement starting judgment condition is met, and the channel quality data of the non-working carrier is measured in a non-service transmission period; and if the CQI value of the working carrier is greater than or equal to the preset measurement starting threshold, the measurement starting judgment condition is not met.
Based on any of the above embodiments, the method further comprises: if a non-working carrier measurement starting instruction sent by a base station is received, or the non-working carrier measurement starting period timer reaches periodically, measuring channel quality data of a non-working carrier in a non-service transmission period; the non-working carrier measurement starting period timer is obtained based on non-working carrier measurement starting period timing information configuration issued by a base station.
Specifically, not only the channel quality data of the working carrier satisfying the non-working carrier measurement start judgment condition can trigger the channel quality measurement of the non-working carrier, but also the terminal can trigger the channel quality measurement of the non-working carrier after receiving the non-working carrier measurement start instruction issued by the base station. Here, the non-working carrier measurement start instruction is used to instruct the terminal to perform channel quality measurement on a non-working carrier, the sending of the non-working carrier measurement start instruction may be implemented by RRC signaling or DCI (Downlink Control Information), and the non-working carrier measurement start instruction may further include a non-working carrier or a non-working carrier group that needs to perform channel quality measurement.
In addition, the base station can also issue non-working carrier measurement starting period timing information to the terminal in advance. The non-working carrier measurement starting period timing information is used for configuring the period of the terminal for executing the non-working carrier channel quality measurement. After receiving the non-working carrier measurement starting period timing information, the terminal can configure a non-working carrier measurement starting period timer based on the non-working carrier measurement starting period timing information, and can trigger the channel quality measurement of the non-working carrier whenever the period of the non-working carrier measurement starting period timer is reached.
According to any of the above embodiments, the method further includes, before the step 120: receiving non-working carrier measurement starting configuration information sent by a base station; the non-working carrier measurement starting configuration information comprises at least one of a non-working carrier measurement starting judgment condition, a preset measurement starting threshold value and non-working carrier measurement starting period timing information. Here, the non-working carrier measurement starting configuration information is used to instruct the terminal to perform a relevant configuration of non-working carrier measurement starting.
Based on any of the above embodiments, in the method, step 130 specifically includes: and if the non-working carrier reporting judgment condition is met, or a non-working carrier reporting indication sent by the base station is received, or the period of a non-working carrier reporting period timer arrives, reporting the channel quality data of the non-working carrier to the base station.
Specifically, after the channel quality data of the non-working carrier is completed, the channel quality data of the non-working carrier can be reported under the condition that the reporting judgment condition of the non-working carrier is met. Here, the non-working carrier reporting judgment condition may be preset by the base station and sent to the terminal, or may be preset by the terminal, where the non-working carrier reporting judgment condition represents that a condition that is required to be satisfied for reporting the channel quality data of the non-working carrier to the base station is satisfied. If the non-working carrier reporting judgment condition is met, reporting, otherwise, not reporting.
The non-working carrier reporting judgment condition comprises at least one of the CQI value of the working carrier being lower than a first preset working carrier reporting threshold, the CQI value of the working carrier being lower than the difference between the CQI value of the non-working carrier and the offset, the CQI value of the non-working carrier being higher than the first preset non-working carrier reporting threshold, and the CQI value of the working carrier being lower than a second preset working carrier reporting threshold and the CQI value of the non-working carrier being higher than the second preset non-working carrier reporting threshold.
Here, the channel quality data of the active carrier includes a CQI value of the active carrier, and the channel quality data of the inactive carrier includes a CQI value of the inactive carrier. After the measurement of the channel quality data of the non-working carrier is completed, it needs to be determined whether a non-working carrier reporting determination condition is satisfied, where the non-working carrier reporting determination condition may be any one or any combination of:
(1) and reporting the channel quality data of the non-working carrier to the base station so as to enable the base station to decide whether to switch to the non-working carrier or to take the non-working carrier as a candidate carrier. The first preset working carrier reporting threshold is the maximum value of the CQI of the working carrier when the preset channel quality data of the non-working carrier is reported.
(2) The CQI value of the active carrier is lower than the difference between the CQI value of the inactive carrier and the offset, here offset. And reporting the channel quality data of the non-working carrier to the base station to enable the base station to decide whether to switch to the non-working carrier or to take the non-working carrier as a candidate carrier.
(3) And reporting the channel quality data of the non-working carrier to the base station so that the base station can decide whether to switch to the non-working carrier or not, or taking the non-working carrier as a candidate carrier. The first preset non-working carrier reporting threshold is the minimum value of the CQI of the non-working carrier when the preset channel quality data of the non-working carrier is reported.
(4) And reporting the channel quality data of the non-working carrier to the base station so as to enable the base station to decide whether to switch to the non-working carrier or not, or taking the non-working carrier as a candidate carrier. Here, the second preset working carrier reporting threshold and the second preset non-working carrier reporting threshold are the maximum CQI value of the working carrier and the minimum CQI value of the non-working carrier when the preset channel quality data of the reporting non-working carrier is reported, respectively. It should be noted that, the values of the first preset working carrier reporting threshold and the second preset working carrier reporting threshold may be the same or different; similarly, the value of the first preset non-working carrier reporting threshold and the value of the second preset non-working carrier reporting threshold may be the same or different.
The terminal can trigger the reporting of the channel quality data of the non-working carrier after receiving the reporting indication of the non-working carrier sent by the base station. Here, the non-working carrier reporting indication is used to indicate the terminal to report the channel quality data of the non-working carrier, the sending of the non-working carrier measurement reporting indication may be implemented by RRC signaling or DCI (physical layer DCI), and the non-working carrier reporting indication may further include a non-working carrier or a non-working carrier group that needs to report the channel quality data.
In addition, the base station can also issue the periodic timing information of the non-working carrier reporting to the terminal in advance. The non-working carrier reporting timing information is used for configuring the period of the terminal for executing the non-working carrier channel quality data reporting. After receiving the reporting timing information of the non-working carrier, the terminal can configure a measurement reporting period timer based on the reporting timing information of the non-working carrier, and can trigger the reporting of the channel quality data of the non-working carrier every time the period of the reporting period timer arrives.
In addition, if the channel quality data of the non-working carrier needs to be reported, the fact that the channel quality data of the non-working carrier does not exist is judged and known, namely no available measurement result exists, and then a special indication is reported. Here, the special indication is used to inform the base station that no measurement results are available at the current terminal.
Based on any of the above embodiments, in the method, step 130 specifically includes: and reporting the channel quality data of each non-reported non-working carrier to the base station after the measurement of the channel quality data of the non-working carrier is stopped.
Specifically, after the measurement of the channel quality data of the non-working carrier is stopped, a large amount of channel quality data of the non-working carrier is obtained, and the channel quality data of the non-working carrier which is not reported is selected from the channel quality data of the non-working carrier to be reported. And at the same time, reporting the channel quality data of the working carrier.
According to any of the above embodiments, the method further includes, before step 130: receiving non-working carrier reporting configuration information sent by a base station; the non-working carrier reporting configuration information includes at least one of a non-working carrier reporting judgment condition, a first preset working carrier reporting threshold, a second preset working carrier reporting threshold, an offset, a first preset non-working carrier reporting threshold, a second preset non-working carrier reporting threshold, and non-working carrier reporting period timing information. Here, the non-working carrier reporting configuration information is used to instruct the terminal to perform the relevant configuration of the non-working carrier reporting.
According to any of the above embodiments, the method further includes, after the step 120: step 140, if the non-working carrier measurement stop condition is met, or a non-working carrier measurement stop instruction sent by the base station is received, or the period of the non-working carrier measurement stop period timer arrives, stopping the measurement of the channel quality data of the non-working carrier; the non-working carrier measurement stopping condition comprises that the CQI value of the working carrier is higher than a preset measurement stopping threshold value, the measurement time length exceeds the preset measurement time length, and at least one of all non-working carrier channel measurements configured by the base station is completed; the non-working carrier measurement stop period timer is obtained based on the configuration of non-working carrier measurement stop period timing information issued by the base station.
Specifically, the terminal detects whether a non-operating carrier measurement stop condition is met or not in real time during the process of performing channel quality data measurement of the non-operating carrier, and stops the measurement of the channel quality data of the non-operating carrier when the non-operating carrier measurement stop condition is met.
The non-working carrier measurement stop condition may be that the CQI value of the working carrier is higher than a preset measurement stop threshold, and at this time, the channel quality of the working carrier is better, and carrier switching is not required, so that channel quality data of the non-working carrier does not need to be reported to the base station. The non-working carrier measurement stop condition may also be that the measurement duration exceeds a preset measurement duration, where the measurement duration is a duration consumed for performing measurement of channel quality data of the non-working carrier, the preset measurement duration is a preset maximum duration consumed for performing measurement of channel quality data of the non-working carrier, and if the measurement duration exceeds the preset measurement duration, the measurement is stopped, and the measurement is adjusted to the working carrier. In addition, the measurement stop condition may be that all the non-operating carriers configured by the base station are channel measured, and if the measurement of the channel quality data of all the non-operating carriers configured by the base station is already finished, the measurement may be stopped.
The terminal can stop the measurement of the channel quality data when the non-working carrier measurement stop condition is met, and can stop the measurement of the channel quality data of the non-working carrier after receiving a non-working carrier measurement stop instruction issued by the base station. Here, the non-working carrier measurement stop instruction is used to instruct the terminal to stop measuring the channel quality data of the non-working carrier, the sending of the non-working carrier measurement stop instruction may be implemented by RRC signaling or DCI, and the non-working carrier measurement instruction may further include a non-working carrier or a non-working carrier group for which the channel quality data needs to be measured and stopped.
In addition, the base station can also issue non-working carrier measurement stop period timing information to the terminal in advance. The non-working carrier measurement stop period timing information is used for configuring a period for the terminal to stop the non-working carrier channel quality data measurement. After receiving the non-working carrier measurement stop period timing information, the terminal may configure a measurement stop timer based on the non-working carrier measurement stop period timing information, and when the measurement stop period timer period arrives, may stop the measurement of the channel quality data of the non-working carrier.
According to any of the above embodiments, the method further includes, before step 140: receiving non-working carrier measurement stop configuration information sent by a base station; the non-working carrier measurement stop configuration information includes at least one of a non-working carrier measurement stop condition, a preset measurement stop threshold, a preset measurement duration, and non-working carrier measurement stop period timing information. Here, the non-operating carrier measurement stop configuration information is used to instruct the terminal to perform relevant configuration for the measurement stop of the non-operating carrier.
Based on any of the above embodiments, in the method, step 130 specifically includes: and if the residual available space exists in the uplink transmission, reporting the channel quality data of the non-working carrier to the base station based on the residual available space.
Specifically, when it is required to report channel quality data of a non-operating carrier to the base station, it may be determined whether there is remaining available space (padding) in uplink transmission. If the residual available space exists, selecting and reporting all or part of the channel quality data of the non-working carrier according to the size of the residual available space, thereby better utilizing uplink channel resources and avoiding resource waste.
According to any of the above embodiments, the method further includes, before the step 120: and receiving a non-working carrier configuration reporting instruction sent by the base station, and determining the non-working carrier to be subjected to channel quality measurement.
In particular, there may be multiple carriers for a non-active carrier for any terminal. The base station may specify the non-working carrier specifically requiring the terminal to perform channel quality reporting by issuing the non-working carrier configuration instruction to the terminal, that is, the terminal only needs to perform channel quality measurement and reporting on the non-working carrier or the non-working carrier group included in the non-working carrier configuration instruction.
Based on any of the above embodiments, a method for reporting channel quality information specifically includes:
the base station groups the full bandwidth carrier or a part of the bandwidth carrier according to the factors such as the terminal capability and the channel quality of the working carrier, and issues the grouping information which needs the terminal to report the channel quality to the terminal through a Radio Resource Control (RRC) signaling. And after receiving the RRC signaling, the terminal acquires the non-working carrier waves needing to be subjected to channel quality reporting.
After determining the non-working carrier required to perform channel quality reporting, the terminal may adjust to the non-working carrier to perform channel quality measurement in a non-service transmission period according to a non-working carrier measurement start instruction issued by the base station.
The terminal can also judge whether the non-working carrier measurement starting judgment condition is met or not through the measured channel quality data of the working carrier, wherein the non-working carrier measurement starting judgment condition is preset by the base station and sent to the terminal, and the non-working carrier measurement starting judgment condition can be that the CQI value of the working carrier is lower than a preset measurement starting threshold. And if the channel quality data of the working carrier meets the starting judgment condition of the non-working carrier measurement, the terminal measures the channel quality data of the non-working carrier in the non-service transmission period.
In addition, the base station may also start a periodic timer for the terminal to be pre-configured with the non-working carrier measurement. If the period of the non-working carrier measurement starting period timer is up, the terminal adjusts to the non-working carrier to measure the channel quality.
After the channel quality measurement of the non-working carrier is completed, the channel quality data of the non-working carrier needs to be reported.
The base station may issue a non-working carrier reporting indication through RRC signaling or DCI (Downlink Control Information), and explicitly indicate the terminal to report all or a specified part of the existing channel quality data of the bandwidth, where the channel quality data may include the working carrier and/or the non-working carrier. And after receiving the instruction issued by the base station, the terminal reports the channel quality data of the designated bandwidth of the base station. If the terminal does not have the channel quality data of the partial bandwidth designated by the base station at the current moment, the channel quality data corresponding to the partial bandwidth can be reported by using a special indication instead.
In addition, the base station can also pre-configure a non-working carrier reporting period timer for the terminal. And if the period of the non-working carrier reporting period timer reaches, the terminal reports the corresponding channel quality data. Here, the reporting of the channel quality data of the working carrier and the reporting of the channel quality data of the non-working carrier may adopt the same reporting period or different reporting periods.
Moreover, the base station can also pre-configure the non-working carrier reporting judgment condition for the terminal. And if the non-working carrier reporting judgment condition is met, reporting the channel quality data of the non-working carrier to the base station. Here, the non-working carrier reporting judgment condition includes at least one of that the CQI value of the working carrier is lower than a first preset working carrier reporting threshold, the CQI value of the working carrier is lower than a difference between the CQI value of the non-working carrier and the offset, the CQI value of the non-working carrier is higher than the first preset non-working carrier reporting threshold, and the CQI value of the working carrier is lower than a second preset working carrier reporting threshold and the CQI value of the non-working carrier is higher than the second preset non-working carrier reporting threshold.
When reporting the channel quality data, it may be determined whether there is padding in uplink transmission at the current time, and if there is padding, selecting to report the channel quality data based on the size of the padding.
In the execution process of the channel quality reporting method, the base station may issue a non-working carrier measurement stop indication through RRC signaling or DCI (physical layer) according to the channel quality of the working carrier, so as to instruct the terminal to stop the channel quality measurement of a part of the bandwidth. And the terminal stops the channel quality measurement after receiving the non-working carrier measurement stop instruction sent by the base station.
In addition, the base station may also configure a non-operating carrier measurement stop condition or a non-operating carrier measurement stop period timer for the terminal in advance. Here, the non-operating carrier measurement stop condition may be at least one of that the CQI value of the operating carrier is higher than a preset measurement stop threshold, that the measurement duration exceeds a preset measurement duration, and that channel measurement of all non-operating carriers configured by the base station is completed. And if the non-working carrier measurement stop condition is met or the period of the non-working carrier measurement stop period timer arrives, the terminal stops the channel quality measurement.
In the method provided by the embodiment of the invention, the base station groups the full bandwidth carrier or the partial bandwidth carrier and issues the configuration instructions of measurement, report and stop to the terminal. The terminal adjusts to a non-working carrier to carry out channel quality measurement or stop measurement according to the measurement configuration set by the base station when the terminal is in a non-service transmission period, and reports available partial bandwidth channel quality data in time according to the reporting configuration of the base station, so that the base station is assisted to better carry out dynamic scheduling and interference avoidance.
