Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings and examples.
The embodiment of the application provides a terminal double-transmission control method, which is characterized in that under the condition that the coverage of a terminal is limited, a double-transmission function is not directly started, and whether the double-transmission function is started is determined according to SINR (signal to interference plus noise ratio) measurement results carried out in N continuous judgment periods. The scheme can give consideration to low power consumption and uplink coverage of the terminal.
The following describes in detail a process for implementing dual-transmission control of a terminal in an embodiment of the present application with reference to the accompanying drawings.
Example one
Referring to fig. 1, fig. 1 is a schematic view of a terminal dual-transmission control flow in an embodiment of the present application. The method comprises the following specific steps:
And when any one or any combination of the following conditions is met, determining that the terminal is in a coverage limited scene:
the terminal is in a subframe bundling (TTI bundling) state, a value of a coding and modulation strategy (MCS) used by the terminal is smaller than a first preset threshold, and a value of a transmission Power Headroom (PHR) reported by the terminal is smaller than a second preset threshold.
In the existing implementation, the dual-transmission function is directly started when the terminal is in the coverage limited scene, and in the embodiment of the present application, the step 102 needs to be executed when the terminal is in the coverage limited scene.
102, the base station determines whether SINRs reported when Signal to Interference plus Noise Ratio (SINR) measurements are performed in N consecutive determination periods are all smaller than a first preset threshold, and if so, executes 103; otherwise, step 104 is performed.
In the embodiment of the present application, when it is determined that the terminal is in a coverage limited scene, statistics is started to be performed on the channel quality of the terminal, specifically as follows:
in each judgment period, for example, 20ms, SINR measurement is performed for the terminal, and one SINR value is reported in each measurement.
Here, the consecutive N judgment periods include consecutive N periods including the current period.
When the terminal is notified to start the dual-transmission function, the terminal is notified through Radio Resource Control (RRC) signaling or Downlink Control Information (DCI) signaling, that is, the RRC signaling or DCI signaling carries indication Information to notify the terminal to start the dual-transmission function.
After the terminal starts the dual-transmission function, uplink dual-transmission can be performed, and uplink coverage of the terminal is improved.
When the base station enters the next judgment period, if the terminal is still in the coverage limited scene, the SINR measurement is continued to determine whether to enable the terminal to start the dual-transmission function, that is, step 102 is executed; and if the terminal is not in the coverage limited scene, ending the current processing flow.
Example two
Referring to fig. 2, fig. 2 is a flowchart of a terminal dual-transmission control in the second embodiment of the present application. The method comprises the following specific steps:
Wherein the second preset threshold is greater than the first preset threshold.
When the terminal is notified to close the dual-sending function, the notification is carried out through RRC signaling or DCI signaling; that is, the indication information is carried in the RRC signaling or DCI signaling to notify the terminal to close the dual-forwarding function.
In step 204, the base station waits for entering the next determination period.
When the base station enters the next judgment period, if the terminal is still in the dual-transmission open state, the SINR measurement is continued to determine whether to close the dual-transmission function of the terminal, that is, step 202 is executed; if the terminal is not in the double-sending open state, the current processing flow is ended.
N in the embodiment of the present application is an integer greater than 0, and the specific value may be configured according to an actual application scenario.
When the coverage limited scene is that the terminal is in a TTI bundling state, determining a first preset threshold value according to an SINR corresponding to the lowest MCS of the TTI bundling;
the second preset threshold value is also determined according to the SINR corresponding to the lowest MCS of the TTI bundling.
Assuming that the SINR value corresponding to the lowest MCS of the TTI bundling is K, the first preset threshold may be K-HYS; the second preset threshold is K + HYS, where HYS is a hysteresis parameter, which may be set to 1dB, but is not limited thereto.
Here, a setting mode of the preset threshold is only an example, and during specific implementation, the setting mode may be specifically set according to an actual application scenario, and is not limited to the above mode.
Based on the same inventive concept, the application provides a terminal double-transmission control device. Referring to fig. 3, fig. 3 is a schematic structural diagram of an apparatus applied to the above technology in the embodiment of the present application. The device includes: a determination unit 301 and a notification unit 302;
