In the general design, take the mobile terminal game service as an example. The relevant characteristics of the game service are: long connection, small data packet, low traffic, low delay, low fault tolerance, and sensitivity to changes in the wireless network environment. Due to the range of perception capabilities of normal people, when the delay in the game business reaches the level of 100ms, you can obviously feel the freeze and the operation is not flexible; when the delay in the game reaches the level of 200ms, the user's operation and game perception feedback are basically Unable to synchronize, seriously affecting user experience. Combining with the network architecture in Figure 1A, it can be seen that the interaction process between mobile phone game service data and network devices includes the access network delay from the mobile phone to the network air interface, and the time-consuming transmission of IP data from the access network to the game server. The process involves the interaction between the mobile phone and various network elements on the network side. Due to the influence of the wireless communication environment, the situation is complicated and involves many related variables. The time-consuming of the interaction process accounts for a large proportion of the overall delay.

In view of the above situation, an embodiment of the present application proposes a method for controlling signal transmission. In this method, when the mobile terminal first detects that the signal receiving state of the mobile terminal is the first signal receiving state, it determines that the signal transmission mode of the mobile terminal is diversity In the transmission mode, the first signal receiving state is used to indicate that the mobile terminal is in a weak signal field, secondly, notify the network equipment to adopt the diversity transmission mode to transmit data signals with the mobile terminal, and finally, control the mobile terminal The radio frequency system transmits the data signal with the network device in the diversity transmission mode. Since mobile terminals are more often scheduled in diversity transmission mode rather than dual-stream space-division multiplexing mode in weak signal fields, mobile terminals can obtain a better decoding success rate, which is conducive to reducing the cost of mobile terminals and network equipment. Transmission delay in the process of interactive data and improve the reliability of data transmission.

Embodiments of the present application will be described below in conjunction with the accompanying drawings.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a signal transmission control method provided by an embodiment of the present application, which is applied to a mobile terminal and can be specifically executed by an application processor or a baseband processor or a SoC. As shown in the figure, this Applied signaling control methods include:

S201. When the mobile terminal detects that the signal receiving state of the mobile terminal is the first signal receiving state, determine that the signal transmission mode of the mobile terminal is the diversity transmission mode, and the first signal receiving state is used to indicate that the mobile terminal is in a weak state. signal field.

Among them, in order to meet the requirements of the LTE communication system in terms of high data rate and high system capacity, the LTE system supports the downlink traffic channel PDSCH to apply Multiple Input Multiple Output (MIMO) technology to achieve average user throughput and spectrum efficiency The best requirements to improve the system transmission rate. MIMO uses multi-distance antenna arrays at the signal transmitting/receiving end, that is, antenna diversity technology is used, and multiple independent channels that do not interfere with each other are opened up from the spatial wireless channel, and a new one-dimensional gain space is obtained, that is, spatial diversity. 1. Utilizing the spatial multiplexing gain provided by the MIMO channel can increase the capacity of the channel, and utilizing the spatial diversity gain provided by the MIMO channel can improve the reliability of the channel and reduce the bit error rate. Mobile terminals based on the LTE system have multiple transmission modes for their downlink data services, among which the diversity transmission mode utilizes the weak correlation of spatial channels, combined with time and/or frequency selectivity, to provide more copies for signal transmission and improve The reliability of signal transmission, thereby improving the signal-to-noise ratio of the received signal and improving the quality of data transmission.

Wherein, the signal receiving state of the mobile terminal can be determined by signal parameters, and when it is detected that the signal receiving state of the mobile terminal is the first signal receiving state, it is determined that the current signal transmission mode of the mobile terminal is the diversity transmission mode, and the first signal receiving state indicates that the mobile terminal The terminal is in a weak signal field, that is, the received signal quality is lower than expected.

Among them, when the mobile terminal is in a weak signal field, the current network signal strength is weak, and at the same time, due to the large signal interference, the bit error rate of the signal received by the mobile terminal is high, resulting in more data packet loss and delay during the game. Large, frequent retransmissions seriously affect the game experience. Therefore, it is necessary to detect whether the mobile terminal is in the first signal state so as to determine whether the mobile terminal is in a weak signal field.

S202. The mobile terminal notifies a network device to transmit data signals with the mobile terminal in the diversity transmission mode.

Wherein, the network device may be a base station, and the mobile terminal notifies the base station to schedule the diversity transmission mode to the mobile terminal, so that both the mobile terminal and the base station use the diversity transmission mode to send and receive data.

Among them, the main principle of the diversity transmission mode is to use the weak correlation of the spatial channel, combined with the selectivity of time and/or frequency, to improve the reliability of signal transmission, thereby improving the signal-to-noise ratio of the received signal and improving the quality of data transmission. In areas with poor channel conditions such as cell edges, handover areas, and shadow areas. In the diversity transmission mode, only one codeword stream is allowed to be diversified. Therefore, the data path in the diversity transmission mode is a single stream, while the data stream in the space division multiplexing mode is dual streams, which are sent using double codewords. For example, the base station has 4 antennas. In the diversity transmission mode, the 4 antennas transmit a bit stream, and a bit stream has the diversity gain formed by 4 antennas. In the space division multiplexing mode, the 4 antennas transmit two bit streams. , a bit stream has the diversity gain of 2 antennas, so that the signal-to-noise ratio is improved on the basis of the original noise unchanged, and compared with the space division multiplexing mode, the decoding process of the diversity transmission mode is simpler and has better decoding Success rate.

S203. The mobile terminal controls a radio frequency system of the mobile terminal to transmit the data signal with the network device in the diversity transmission mode.

Wherein, after determining that the data signal is transmitted in the diversity transmission mode, the mobile terminal controls the radio frequency system to use the diversity transmission mode to send and receive the data signal.

It can be seen that in the embodiment of the present application, when the mobile terminal first detects that the signal receiving state of the mobile terminal is the first signal receiving state, it determines that the signal transmission mode of the mobile terminal is the diversity transmission mode, and the first signal receiving state It is used to indicate that the mobile terminal is in a weak signal field, secondly, notify the network equipment to adopt the diversity transmission mode to transmit data signals with the mobile terminal, and finally, control the radio frequency system of the mobile terminal to adopt the diversity transmission mode to communicate with the mobile terminal The network device transmits the data signal. Since the mobile terminal is scheduled in a diversity transmission mode instead of a dual-stream space division multiplexing mode in a weak signal field, the diversity gain brought by the diversity transmission mode can improve the signal-to-noise ratio, thereby enabling the mobile terminal to obtain better The decoding success rate is high, which is beneficial to reduce the transmission delay in the process of data exchange between mobile terminals and network equipment and improve the reliability of data transmission.

In the embodiment of the present application, multiple implementations may be used to detect whether the signal receiving state of the mobile terminal is the first signal receiving state, that is, to detect whether the mobile terminal is in a weak signal field. Several implementations are described below as examples.

In a possible example, when it is detected that a signal noise ratio (signal noise ratio, SNR) is less than a preset SNR, it is determined that the signal receiving state of the mobile terminal is the first signal receiving state.

Among them, SNR is the ratio between the power of the signal received by the mobile terminal and the power of the noise generated by the mobile terminal. Generally, in a WLAN, an SNR higher than 20 decibels indicates that the signal field of the mobile terminal is better, and an SNR less than 10 decibels indicates that the mobile terminal The signal field of the terminal is poor. For example, the preset SNR is 10 decibels, and an SNR lower than 10 decibels indicates that the mobile terminal is in a weak signal field. In the embodiment of the present application, by comparing the preset SNR with the detected SNR of the signal received by the mobile terminal, it is enough to determine whether the mobile terminal is in a weak signal field. There is no unique limitation on the specific setting value of the preset SNR. SNR can also be other values.

In a possible example, when it is detected that a reference signal receiving power (reference signal receiving power, RSRP) is less than a preset RSRP, it is determined that the signal receiving state of the mobile terminal is the first signal receiving state.

Among them, RSPR is one of the key parameters that can represent the wireless signal strength in the LTE network and one of the physical layer measurement requirements. It is the average value of the signal power received on all REs (resource elements) that carry reference signals in a certain symbol. For example, the preset RSRP is -85dBm, and the RSRP lower than -85dBm indicates that the mobile terminal is in a weak signal field. In the embodiment of the present application, by comparing the preset RSRP with the detected RSRP of the signal received by the mobile terminal, it is enough to determine whether the mobile terminal is in a weak signal field. There is no unique limitation on the specific setting value of the preset RSRP. RSRP can also be other values.

In a possible example, when it is detected that the number of resource blocks (resource block, RB) is less than a preset RB threshold, it is determined that the signal receiving state of the mobile terminal is the first signal receiving state.

Among them, the number of RB is used to indicate the effective bandwidth of data transmission, which will affect the rate of data transmission. When the RB value is less than the preset threshold, it means that the efficiency of data transmission is very poor. For example, the preset RB threshold is 5, RB A value below 5 indicates that the mobile terminal is in a weak signal field. In the embodiment of the present application, by comparing the preset RB with the detected actual RB of the mobile terminal, it is sufficient to determine whether the mobile terminal is in a weak signal field. There is no unique limitation on the specific value of the preset RB. The preset RB Other values are also possible.

It can be seen that according to the preset channel parameters, it is determined that the signal receiving state of the mobile terminal is the first signal receiving state, that is, it is determined that the mobile terminal is in a weak signal field, and the quality of the received signal at this time is poor. The adjustment of the signal transmission mode of the mobile terminal is beneficial to improve the signal quality.

In a possible example, the notifying the network equipment of using the diversity transmission mode to transmit data signals with the mobile terminal includes: sending a preset signaling to the network equipment, the preset signaling carrying a rank indication RI, where the RI is used to instruct the network device to transmit data signals with the mobile terminal in the diversity transmission mode.

Among them, in a multiple-input multiple-output MIMO system, there can be Nt transmitting antennas and Nr receiving antennas, the transmission channel can be identified by a matrix, and the rank indicator RI identifies the rank of the transmission channel, which can be regarded as the The number of independent parallel signals can also be understood as the number of streams that the wireless transmission channel can independently transmit data. For example, when RI is equal to 1, the data stream is a single stream, corresponding to the diversity transmission mode. The stream is dual-stream, which corresponds to the dual-stream space division multiplexing mode.

Wherein, the mobile terminal sends preset signaling to the network device, and the preset signaling carries rank indicator RI and the value of RI is 1, which means that the mobile terminal expects the network device to schedule the diversity transmission mode to the mobile terminal, so that the network device can and transmitting the first data signal to the mobile terminal in a diversity transmission mode.

It can be seen that in this example, the mobile terminal tunes the rank indication RI and sends the preset signaling to the network device to carry the rank indication RI. When the RI is 1, it means that the mobile terminal expects the network device to schedule diversity transmission mode to the mobile terminal.

In a possible example, the method further includes: when it is detected that the SNR is greater than or equal to the preset SNR, determining that the signal receiving state of the mobile terminal is a second signal receiving state, and the second signal receiving state uses To indicate that the mobile terminal is not in a weak signal field; maintain the current signal transmission mode of the mobile terminal.

Wherein, when it is detected that the SNR is greater than or equal to the preset SNR, it indicates that the channel environment of the mobile terminal is good, and the mobile terminal can maintain the current signal transmission mode. When the current signal transmission mode is the diversity transmission mode, continue to use the current mode For signal transmission, when the current signal transmission mode is dual-stream space-division multiplexing mode, continue to carry out signal transmission in the current mode, that is, without any adjustment.

It can be seen that this example shows that the signal transmission control method provided by this application is applicable to the situation where the mobile terminal is in a weak signal field, and when the mobile terminal is not in a weak signal field, there is no need to adjust the signal transmission mode of the mobile terminal.

In a possible example, a target application program runs in the foreground of the mobile terminal, and the running interface of the target application program is a multiplayer online battle arena (MOBA) scene interface.

Wherein, the target application program may be a game application program, a video application program, etc., which are not limited here.

In the specific implementation, the mobile terminal can sample and analyze multiple data packets through the baseband processor, identify the MOBA scene of the target application program running in the foreground through the format of the data packet and other attributes, and can also obtain the scene information sent by the foreground application program through the application processor. , so that the operating system can know the MOBA scenario of the target application program running in the foreground in a timely manner, and there is no unique limitation here. That is to say, the trigger condition for the mobile terminal to execute the above step S201 may be that the mobile terminal detects that the current running scenario is the above MOBA scenario, so as to realize exclusive optimization control for the MOBA scenario.

It can be seen that in this example, the mobile terminal only performs identification and exclusive optimization control for MOBA scenarios, which is beneficial to resource balance and improves battery life.
