Description

Method, system and device for controlling uplink discontinuous transmission state

technical field

The present invention relates to the control technology of the radio frequency signal in the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, in particular to a control method for the uplink discontinuous transmission (DTX, Discontinuous transmission) state in the TD-SCDMA system, systems and devices.

Background technique

In the TD-SCDMA system, the transmission of DTX radio frequency signals between the terminal and the network side is a standard technology and function defined by the 3GPP international standard. When a wireless link is established between the terminal and the network side in the TD-SCDMA system, if there is no communication interaction between the terminal and the network side temporarily, that is, there is no transmission data block provided by the terminal or the network side for any given coded composite transmission When the channel (CCTrCH) is used to transmit radio frequency signals, the terminal or the network side will turn off its own radio frequency transmitter, stop the continuous transmission of radio frequency signals, and enter the DTX state.

When the radio frequency signal is transmitted between the terminal and the network side through a wireless link, it can be divided into an uplink DTX radio frequency signal and a downlink DTX radio frequency signal according to different transmission directions. Among them, the radio frequency signal of the uplink DTX represents the non-continuous transmission radio frequency signal transmitted by the terminal to the network side. The radio frequency signal is transmitted continuously, and the radio frequency signal transmitted at this time is also a special burst.

Figure 1 is a schematic diagram of the comparison between the radio frequency signal of the uplink DTX and the radio frequency signal of the uplink continuous transmission in the prior art. Milliseconds, each wireless frame in the non-uplink DTX radio frequency signal, that is, every 10 milliseconds a wireless frame carries a data block to send; for the uplink DTX radio frequency signal, within a transmission cycle, that is, the special burst generation cycle ( In SBGP, Special burstgeneration period), the SBGP is set to 40 milliseconds. Except for the first wireless frame, that is, the first 10 milliseconds of the wireless frame to be transmitted, a special burst is transmitted, and no transmission is made in the remaining wireless frames. sudden.

After the network side establishes a wireless link with the terminal, in order to enable the terminal to enter the uplink DTX state, the method shown in Figure 2 is adopted. Figure 2 is a flowchart of a method for the prior art terminal to enter the uplink DTX state, and the specific steps are:

Step 201, the network side sends an uplink physical channel control message to the terminal, and the message carries an indication of entering the uplink DTX state;

Step 202: After receiving the message, the terminal confirms that it will enter the uplink DTX state, turns off its own radio frequency transmitter, stops continuous transmission of radio frequency signals, and enters the uplink DTX state.

It can be seen that when the terminal enters the uplink DTX state, it only needs to transmit discontinuous radio frequency signals instead of continuous radio frequency signals. Since there is no continuous radio frequency signal transmission, the terminal has the advantages of power saving and interference reduction when entering the uplink DTX state, but at the same time, the cycle of synchronization control and power control of the terminal on the network side becomes sparse, especially in situations such as high-speed mobile, Under harsh and complex communication scenarios such as deep fading and strong interference. When the terminal enters the uplink DTX state, since the uplink DTX radio frequency signal transmitted by the terminal itself has discontinuous signal transmission characteristics, compared with the non-uplink DTX radio frequency signal transmission characteristics, the wireless link interaction between the network side and the terminal is different. The control efficiency is significantly reduced. If the period of the synchronization and power control mechanism for the terminal on the network side is much shorter than the transmission period in the uplink DTX state, the network side will not be able to obtain the The uplink radio frequency signal sent by the terminal causes abnormal phenomena such as out-of-synchronization or disconnection of the wireless link between the terminal and the network side.

In order to overcome the above problems, when the network side cannot obtain the uplink radio frequency signal sent by the terminal within the period of the network side's synchronization and power control mechanism for the terminal, it needs to instruct the terminal to turn off the uplink DTX state and transmit non-uplink DTX radio frequency signals process. However, in the existing technical standards and implementation methods, when the network side instructs the terminal to enter the uplink DTX state, the uplink physical channel control message carries the entry into the uplink DTX state to indicate the default uplink DTX state, that is, the default uplink DTX state is on, and always remains It is effective, but there is no method or process to instruct the terminal to turn off the uplink DTX state, which means that the uplink DTX state of the terminal cannot be controlled between on and off.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

Because in the existing technical standards and implementation methods, when the network side instructs the terminal to enter the uplink DTX state, there is no method or process to instruct the terminal to turn off the uplink DTX state, so that the uplink DTX state of the terminal cannot be controlled between on and off. A terminal entering the uplink DTX state will prevent the network side from obtaining the uplink radio frequency signal sent by the terminal within the period of the network side's synchronization and power control mechanism for the terminal, resulting in out-of-synchronization or disconnection of the wireless link between the terminal and the network side and other abnormal phenomena.

In order to overcome this problem, when the network side wants to close the uplink DTX state of the terminal, the present invention sends to the terminal an uplink physical channel control message that does not carry a special burst timing arrangement indication, instructing the terminal to close the uplink DTX state and open its own radio frequency transmission The machine resumes transmitting continuous radio frequency signals.

In the present invention, before the network side determines to close the DTX state that the terminal enters, the network side detects that the terminal cannot obtain the uplink radio frequency signal sent by the terminal within the period of the network side's synchronization and power control mechanism for the terminal, such as communication with the network side Abnormal phenomena such as loss of synchronization or disconnection of the wireless link.

Part of the content contained in the existing uplink physical channel control message is shown in Table 1,

Table I

When the special burst timing security indication is included in the uplink physical channel control message, the existing uplink physical channel control message must also carry SBGP, which is mainly used to configure the period length of the uplink DTX state, and its specific meaning is shown in the table Two shows:

Table II

It can be seen from Table 2 that the value range of SBGP is 0 to 7, and the corresponding time period is 20 milliseconds to 2560 milliseconds.

The attribute of the special burst timing arrangement indication in Table 1 is optional, indicating that whether to carry the special burst timing arrangement indication in the uplink physical channel control message is configured according to needs. In the prior art, when the uplink physical channel control message carries a special burst scheduling indication, it indicates that the SBGP of the terminal in the uplink DTX state needs to be updated, so the uplink physical channel control message also carries the setting If the SBGP of the parameter value does not carry a special burst scheduling indication, the SBGP of the terminal in the uplink DTX state remains unchanged.

The present invention utilizes the optional attribute of the special burst timing arrangement indication, redefines it when it is not carried, and uses it as an indication to close the uplink DTX state of the terminal, namely:

When the special burst scheduling indication is carried in the uplink physical channel control message, it indicates that the uplink DTX status of the terminal is on, that is, it remains unchanged from the existing standard definition, and is updated according to the SBGP parameter value carried in the uplink physical channel control message The time period of the uplink DTX state; here, if the carried SBGP parameter value is the time period when the terminal is currently in the uplink DTX state, it can be directly maintained in the uplink DTX state without adjustment;

When the special burst timing arrangement indication is not carried in the uplink physical channel control message, it indicates that the uplink DTX state of the terminal is off, that is, the existing standard definition is changed to the uplink DTX state off.

For example, SBGP is 2, that is, 80 milliseconds. The specific steps are:

Step 301, the network side determines that the terminal will turn off the uplink DTX state;

Before this step, the network side may detect that the wireless communication link with the terminal is abnormal or receive a request to close the uplink DTX status initiated by the terminal, which is not limited here;

Step 302, the network side sends an uplink physical channel control message that does not carry a special burst scheduling instruction to the terminal, instructing the terminal to turn off the uplink DTX state, that is, instructing the terminal to turn on its own radio frequency transmitter and resume transmitting continuous radio frequency signals.

In this embodiment, when the network side needs to change the time period of the uplink DTX state of the terminal in the uplink DTX state, it can also carry the special burst scheduling indication and the SBGP parameter value, so that the terminal can be instructed to change the time period of the uplink DTX state. The time period of the DTX state is up.

Specifically, the network side sends an uplink physical channel control message carrying a special burst scheduling indication and a special burst generation period to the terminal, instructing the terminal to confirm that it continues to be in the uplink DTX state according to the carried burst scheduling indication, and instructing the terminal to continue in the uplink DTX state according to the The carried special burst generation period determines whether to adjust the time period in the uplink DTX state: when the special burst generation period is the current time period in which the terminal is in the DTX state, it indicates no adjustment; otherwise, it instructs the terminal to adjust according to the special burst The generation period adjusts the time period in the uplink DTX state.

In the present invention, the network side may be the Universal Terrestrial Access Network (UTRAN) side.

Fig. 4 is a flow chart of the terminal side control method for the uplink discontinuous transmission state provided by the present invention, assuming that the UE has established a wireless link with the network side, and the UE enters the uplink DTX state, and the time period of the uplink DTX state is the uplink physical channel control The SBGP parameter value carried in the message can also be the default value of the SBGP parameter. For example, SBGP is 2, that is, 80 milliseconds. The specific steps are:

Step 401, the terminal judges whether the uplink physical channel control message is received, if yes, then execute step 402; if not, then return to step 401 to continue receiving the uplink physical channel control message;

Step 402, the terminal determines whether the message carries a special burst scheduling indication, if not, execute step 403; if yes, execute step 404;

Step 403, the terminal turns off the uplink DTX state, that is, turns on its own radio frequency transmitter, and resumes transmitting continuously transmitted radio frequency signals;

Step 404 , the terminal continues to maintain the uplink DTX state, and updates the configured uplink DTX state period according to the carried SBGP parameter value.

In the present invention, the delivery of the SBGP parameter value carried in the uplink physical channel control message is consistent with the prior art.

In this embodiment, when the confirmation carries the special burst timing arrangement indication and the special burst generation period, the terminal confirms to continue to be in the uplink DTX state according to the carried burst timing arrangement;

Determine whether to adjust the time period in the uplink DTX state according to the carried special burst generation period: when the special burst generation period is the current time period when the terminal is in the DTX state, do not adjust; otherwise, according to the special burst generation period Adjust the time period in the uplink DTX state.
