Description

Configuration method of channel quality indication reporting period, terminal and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a terminal, and a network side device for configuring a Channel Quality Indicator (CQI) reporting period.

Background

Adaptive Modulation and Coding (AMC) techniques can improve the spectral efficiency and throughput of the system by dynamically selecting a Modulation and Coding Scheme (MCS) that matches the channel conditions. In the prior art, a base station issues a reference signal to a terminal, the terminal estimates a channel condition and feeds back the channel condition to the base station in a CQI form, and the base station selects an MCS according to the CQI fed back by the terminal. Currently, there are two configurations of periodic and aperiodic CQI reporting. The specific periodic parameter in the periodic reporting mode is configured by Radio Resource Control (RRC) signaling.

In a fourth Generation mobile communication (4G) high-speed moving scenario, taking a high-speed rail communication scenario as an example, since a train runs at a high speed, a channel changes faster, and if a feedback cycle interval of a CQI is larger, a CQI fed back by a terminal received by a base station is outdated; if the interval of the CQI feedback period is small, more uplink channel resources are occupied, and overhead is large. In the existing system, the base station conservatively selects the MCS according to the CQI fed back by the terminal, resulting in a limited transmission rate of the system.

Specifically, in the current high-speed rail communication scenario, the networking mode of the Base station is as shown in fig. 1, the Base station is deployed in a zigzag shape on both sides of the rail, and each 3 Remote Radio Heads (RRHs) are connected to a Base Band Unit (BBU) to form a cell. In a high-speed rail communication scene, the motion track and the speed of a train are relatively fixed, and a rice channel with a direct path as a main channel environment is used as a channel environment between a base station and a relay (serving as a terminal form) at the top of a carriage, so that the predictability is high. When a train runs in a cell center position (such as an area 1 in fig. 1), the CQI can be fed back in a larger period, and the CQI between two feedback intervals can be obtained according to a predicted channel and the CQI reported by a user before; when a train operates at a cell edge position (such as area 2 in fig. 1), in order to measure the interference of the neighboring cell, the CQI should be fed back at a small period. The current CQI reporting period is configured by RRC signaling, and the configuration period is generally hundreds of milliseconds.

In a Fifth Generation mobile communication (5G) New wireless (New Radio, NR) scheme design, a performance index of a mobile speed as high as 500 km/h needs to be satisfied, in such a scenario, a time from a cell center to a cell edge of a terminal may be ten seconds, and if a CQI reporting period of a user located at the cell edge and the cell center is adjusted through a conventional RRC signaling, frequent transmission of the RRC signaling is required, which causes an excessive overhead, so a configuration scheme suitable for the CQI reporting period in a high-speed mobile scenario is urgently needed.

Referring to fig. 2, a flow of a configuration method of a CQI reporting period is shown in the figure, where an execution main body of the method is a terminal, and the terminal may be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the specific steps are as follows:

step 201, acquiring a first CQI reporting period in a first signaling;

in this embodiment of the present invention, optionally, the first CQI reporting period includes: more than two time periods and CQI reporting period information corresponding to each time period. Therefore, the reporting periods of the CQI in different time periods can be configured through the first signaling, and the reporting periods of the CQI in different scenes can be adjusted by less signaling in a high-speed mobile scene or other scenes.

The following reporting period with the first CQI includes: two time periods and two CQI reporting period information corresponding to each time period are taken as examples, and more than two cases are similar to this and will not be described again here.

For example: the first CQI reporting period may be in the form of: { Period ₁ ，T ₁ ，Period ₂ ，T ₂ I.e. over a time period T ₁ Inner user Period ₁ Reporting CQI in time period T ₂ Period of internal user ₂ And reporting the CQI. The specific values of the above parameters may be determined by the moving speed of the user and the location of the network side device (e.g., base station), taking the scenario of fig. 1 as an example, so that the user is located in the time period T of the cell center ₁ The Period of the internal reported CQI is Period ₁ Users operating at cell edgeTime period T of the edge ₂ The Period of the internal reported CQI is Period ₂ 。

It should be noted that, a value set of the CQI reporting period information and the time period may be preset, and specific content of the CQI reporting period information may be index information corresponding to a value of the CQI reporting period.

In this embodiment of the present invention, optionally, the first signaling is Radio Resource Control (RRC) signaling.

Step 202, detecting whether a second CQI reporting period exists in a second signaling; if a second CQI reporting period is detected in the second signaling, go to step 203; if the second CQI reporting period is not detected in the second signaling, go to step 204;

in this embodiment of the present invention, optionally, the second CQI reporting period includes: and the CQI configuration information is equivalent to a new CQI reporting period, and the original CQI reporting period can be updated by utilizing the CQI configuration information, so that the defect that the CQI reporting period is configured only through one signaling is avoided.

Further, the CQI configuration information may be Index information (Index) corresponding to a value of the CQI reporting period, so that overhead required for issuing the configuration information by the network side can be reduced. The bit number of the CQI configuration information is determined by the value number of the preset CQI reporting period.

In the embodiment of the present invention, optionally, the second signaling is Downlink Control Information (DCI).

The mode of configuring the CQI reporting period through the DCI comprises the following steps: an N-bit CQI configuration (CQI-Config) message is added to the DCI, and the CQI configuration message may be an Index (Index) value of a CQI reporting period. When the reporting period of the CQI needs to be adjusted, the network side equipment can issue the CQI configuration information through the DCI, wherein the specific value of N is determined by the number of preset values of the reporting period of the CQI, and N is more than or equal to 1.

Step 203, configuring a CQI reporting period according to the second CQI reporting period;

that is, if the second CQI reporting period is detected in the corresponding field of the second signaling, the reporting period of the CQI is configured according to the second CQI reporting period, thereby implementing fast adjustment of the reporting period of the CQI through the second signaling.

And step 204, configuring the reporting period of the CQI according to the first reporting period of the CQI.

That is, if the second CQI reporting period is not detected in the corresponding field of the second signaling, the reporting period of the CQI is configured according to the first CQI reporting period.

Therefore, the defect that the CQI reporting period is configured only based on the RRC signaling can be overcome, the reporting period of the CQI can be quickly adjusted through the second signaling, and the problem that the overhead is overlarge due to the fact that the RRC signaling needs to be frequently sent in certain scenes when the CQI reporting period is adjusted through the RRC signaling in the prior art is solved.

step 301, sending a first signaling and a second signaling to a terminal, where the first signaling includes a first CQI reporting period, so that the terminal configures a CQI reporting period according to a second CQI reporting period when detecting that the second signaling includes the second CQI reporting period; or the terminal configures the reporting period of the CQI according to the first reporting period when detecting that the second signaling does not contain the second reporting period of the CQI.

In this embodiment of the present invention, optionally, the first signaling is RRC signaling, and the second signaling is DCI.

In this embodiment of the present invention, optionally, the first CQI reporting period includes: more than two time periods and CQI reporting period information corresponding to each time period. The following reporting period with the first CQI includes: two time periods and two CQI reporting period information corresponding to each time period are taken as examples, and more than two cases are similar to this and will not be described again here.

For example: the first CQI reporting period may be in the form of: { Period ₁ ，T ₁ ，Period ₂ ，T ₂ I.e. over a time period T ₁ Period of internal user ₁ Reporting CQI in time period T ₂ Period of internal user ₂ And reporting the CQI. The specific values of the above parameters may be determined by the moving speed of the user and the location of the network side device (e.g., base station), taking the scenario of fig. 1 as an example, so that the user is located in the time period T of the cell center ₁ The Period of the internal reported CQI is Period ₁ Time period T when user operates at cell edge ₂ The Period of the internal reporting CQI is Period ₂ 。

In the embodiment of the present invention, optionally, the CQI reporting period information is index information corresponding to a value of the CQI reporting period.

In this embodiment of the present invention, optionally, the second CQI reporting period includes: CQI configuration information.

In the embodiment of the present invention, optionally, the CQI configuration information is index information corresponding to a value of a CQI reporting period.

In the embodiment of the present invention, optionally, the bit number of the CQI configuration information is determined by the number of values of a preset CQI reporting period.

Taking the second signaling as DCI as an example, the way of configuring the CQI reporting period through DCI is as follows: an N-bit CQI configuration (CQI-Config) message is added to the DCI, and the CQI configuration message may be an Index (Index) value of a CQI reporting period. When the reporting period of the CQI needs to be adjusted, the network side device may issue CQI configuration information through the DCI, that is, issue an index value of a value of the CQI reporting period, where a specific value of N is determined by the number of preset values of the CQI reporting period, and N is greater than or equal to 1.
