However, adding AGC may result in increased power consumption of the terminal device.

Detailed Description

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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.

Referring to fig. 1, fig. 1 is an architecture diagram of a communication system according to an embodiment of the present disclosure. As shown in fig. 1, the communication system may include a terminal device 101 and a network device 102. The terminal device 101 is an entity for receiving or transmitting signals on the user side. The terminal device may be a mobile phone (mobile phone), a wearable device, a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR), and the like. The embodiment of the present application does not limit the specific technology and the specific device form adopted by the terminal device. The network device 102 is an entity on the network side for transmitting or receiving signals. For example, the network device may be an evolved NodeB (eNB), a transmission point (TRP), a next generation base station (gNB) in the NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices.

In this embodiment, the terminal device 101 may receive the signal sent by the network device 102, but because the signal sent by the network device 102 may experience different channels during transmission, or because the terminal device 101 may be in a fast moving state when receiving the signal, the fluctuation amplitude of the received signal may be relatively large. Therefore, Automatic Gain Control (AGC) can be added before the terminal device 101 receives data to stabilize the received signal amplitude within a reasonable range. The AGC may be a hardware module in the terminal device, for example, may be a circuit integrated in the terminal device, so as to amplify or reduce signals with different strengths by using different gains.

It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems. For example: a Long Term Evolution (LTE) system, a 5th generation (5G) mobile communication system, and a 5G New Radio (NR) system. Optionally, the method in this embodiment of the present application is also applicable to various future communication systems, for example, a 6G system or other communication networks, which is not limited in this application.

Referring to fig. 2, fig. 2 is a flowchart illustrating a gain control method according to an embodiment of the present disclosure. The gain control method may be implemented by the terminal device, or may be implemented by a chip in the terminal device. As shown in fig. 2, the gain control method includes, but is not limited to, the following steps S201 to S203.

Step S201, the terminal equipment determines a receiving gain; if the first preset condition is met, the receiving gain is determined by the received first signal; and if the first preset condition is not met, the receiving gain is the historical receiving gain.

In the embodiment of the application, the terminal device may determine the receiving gain according to different scenarios. For example, the terminal device may determine the reception gain according to scene 1 or scene 2. The scene 1 may be a scene satisfying a first preset condition; in this scenario 1, the receive gain may be determined by the received first signal. Scene 2 may be a scene that does not satisfy the first preset condition; in this scenario 2, the reception gain may be determined by a historical reception gain.

The first signal may be a downlink signal transmitted through a downlink channel. It is understood that the first signal is a signal received after the terminal device determines that the first preset condition is satisfied. Specifically, under the condition that the terminal device determines that the scenario satisfies the first preset condition, the terminal device may introduce one data reception before receiving the paging message transmitted on the downlink channel, that is, introduce reception of the first signal, so as to determine the reception gain through the first signal.

It should be noted that the above-mentioned historical reception gain may be understood as a reception gain used when a paging message is received last time. Optionally, in the case of the historical reception gain used when the paging message was received last time, the historical reception gain may also be a reception gain used when the paging message was received last time, which is not limited in this application.

Please refer to fig. 3A and fig. 3B, wherein fig. 3A is a schematic diagram of a scene 1, and fig. 3B is a schematic diagram of a scene 2. In fig. 3A, the AGC may indicate a process in which the terminal device determines a reception gain, and a Paging Channel (PCH) may indicate a process in which the terminal device receives a Paging message. As can be seen from fig. 3A, the terminal device separately receives data once before receiving the paging message, so as to calculate the reception gain, thereby ensuring the accuracy of the reception gain at the paging time. As can be seen from fig. 3B, the terminal device directly uses the historical reception gain for receiving the paging message, so that the energy consumption of the terminal device can be reduced.

Before the terminal device performs the scene determination, a sliding observation window may be provided to observe the fluctuation of the signal in the sliding observation window, and determine the scene according to the fluctuation of the signal. Wherein the sliding observation window is a time window of a fixed duration that varies with time. Optionally, the fixed duration may be N paging cycles, where N is a positive integer. That is, the paging channel at N paging cycles can be observed within the sliding observation window.

In one implementation, the terminal device may further determine a Reference Signal Receiving Power (RSRP) of each paging cycle within the sliding observation window.

In one implementation, the terminal device may also determine a Signal to Interference plus Noise Ratio (SINR) for each paging cycle within the sliding observation window.

The network device may periodically send paging data to the terminal device, so that a time duration between two adjacent paging data being received by the terminal device may be one paging cycle. It should be noted that, an RSRP value and an SINR value corresponding to the reference signal in each paging cycle exist in each paging cycle, and the RSRP value and the SINR value in each paging cycle are recorded, so that different scenes can be conveniently determined in the following process.

In one implementation, the terminal device may also determine a paging decoding result for each paging cycle within the sliding observation window.

Wherein, the paging decoding result may include any one of the following: the terminal device detects paging Downlink Control Information (DCI), and decodes a Physical Downlink Shared Channel (PDSCH) scheduled by the paging DCI correctly; the terminal equipment detects paging DCI and decodes errors of a PDSCH scheduled by the paging DCI; the terminal device does not detect the paging DCI.

The paging DCI can be obtained by decoding paging data transmitted by the network. Under the condition that the terminal equipment detects the paging DCI, the corresponding PDSCH position can be obtained according to the paging DCI, and the paging message can be finally obtained by decoding the PDSCH.

Specifically, the paging DCI may be configured by the network. If the network configures the paging DCI, the terminal device may detect the paging DCI. And if the terminal equipment detects the paging DCI and correctly decodes the PDSCH scheduled by the paging DCI, adding 1 to the correctly decoded PDSCH. And if the terminal equipment detects the paging DCI and the PDSCH scheduled by the paging DCI is decoded wrongly, adding 1 to the number of the PDSCH decoded wrongly.

For example, it is assumed that the number of correctly decoded PDSCH is Right _ cnt and the number of incorrectly decoded PDSCH is Err _ cnt. If the terminal equipment detects the paging DCI and the PDSCH decoding is correct, recording Right _ cnt as Right _ cnt + 1; if the terminal device detects paging DCI and PDSCH decoding error, recording Err _ cnt as Err _ cnt + 1; the initial values of Right _ cnt and Err _ cnt may be 0.

It should be noted that, if the terminal device does not detect the paging DCI, the network may not configure the paging DCI, but this does not mean that the paging decoding fails. It can be understood that, when the terminal device detects the paging DCI and decodes the PDSCH scheduled on the paging DCI incorrectly, it may be considered that the paging decoding has failed.

Before the terminal equipment judges the scene, a sliding observation window is set, the RSRP value, the SINR value and the paging decoding result of each paging cycle in the sliding observation window are determined, the RSRP fluctuation value, the SINR fluctuation value and the paging decoding failure rate can be calculated, whether the terminal equipment meets a first preset condition or not can be judged according to the RSRP fluctuation value, the SINR fluctuation value, the paging decoding failure rate and the paging decoding result of the current paging cycle, and therefore a more appropriate mode is selected to determine the receiving gain.

In one implementation, the aforementioned first preset condition may include one or more of the following: the RSRP fluctuation value is larger than a first threshold value; the SINR fluctuation value is greater than a second threshold value; the failure rate of paging decoding is greater than a third threshold value; or the terminal equipment detects the paging DCI and decodes the PDSCH scheduled by the paging DCI wrongly.

The RSRP fluctuation value may be a difference between an RSRP maximum value and an RSRP minimum value corresponding to a paging cycle in the sliding observation window, and the SINR fluctuation value may be a difference between an SINR maximum value and an SINR minimum value corresponding to the paging cycle in the sliding observation window.

For example, assuming that the RSRP value corresponding to the second paging cycle is the largest and the RSRP value corresponding to the fifth paging cycle is the smallest in the sliding observation window, the RSRP fluctuation value may be the difference between the RSRP value of the second paging cycle and the RSRP value of the fifth paging cycle. Similarly, the calculation method of the SINR fluctuation value is the same as the calculation method of the RSRP fluctuation value, and is not described herein again.

It should be noted that the RSRP fluctuation value and the SINR fluctuation value may reflect the magnitude of the signal fluctuation. If the RSRP fluctuation value or the SINR fluctuation value is larger, the amplitude of signal fluctuation is larger; and if the RSRP fluctuation value or the SINR fluctuation value is smaller, the signal fluctuation amplitude is smaller.

Optionally, the terminal device may preset a first threshold and a second threshold, and when the RSRP fluctuation value is greater than the first threshold, or the SINR fluctuation value is greater than the second threshold, it is determined that the signal fluctuation amplitude exceeds the preset threshold, which may be determined as scenario 1, that is, the received first signal is used to determine the reception gain.

When the RSRP fluctuation value is greater than the first threshold value or the SINR fluctuation value is greater than the second threshold value, the terminal device is determined as scenario 1, and the first signal may be used to determine the reception gain under the condition of a large signal fluctuation amplitude, so as to ensure that the reception gain at the paging time is reasonable.

The paging decoding failure rate may be a ratio between the number of PDSCH decoding errors and the total PDSCH decoding number; and the total PDSCH decoding number is the sum of the number of PDSCH decoding errors and the number of PDSCH decoding errors.

It should be noted that the failure rate of paging decoding may reflect the ratio of the number of paging decoding errors in N paging cycles in the sliding observation window. If the value of the paging decoding failure rate is larger, the number of the paging decoding errors in the sliding observation window is more; if the value of the paging decoding failure rate is smaller, it means that the number of paging decoding errors in the sliding observation window is smaller.

Optionally, the terminal device may preset a third threshold, and when the paging decoding failure rate is greater than the third threshold, it indicates that the number of paging decoding errors in the sliding observation window exceeds the preset threshold, and it may be determined as scenario 1, that is, the receiving gain is determined by the received first signal.

For example, assuming that the fixed duration of the sliding observation window is 8 paging cycles, when the sliding observation window is full of 8 paging cycles, the fraction of the number of paging decoding errors in the sliding observation window may be determined by calculating the failure rate of paging decoding of the 8 paging cycles. Assuming that the third threshold is 0.5, that is, in 8 paging cycles in the sliding observation window, if there are 5 or more paging cycles with paging decoding errors, it is determined that the paging decoding failure rate is greater than the third threshold, and it can be determined as scenario 1; if the paging decoding of 4 paging cycles or less is wrong, the failure rate of the paging decoding is judged to be less than or equal to a third threshold value, and then other conditions can be judged.

Optionally, if the terminal device detects the paging DCI of the current paging cycle and decodes the PDSCH scheduled by the paging DCI incorrectly, it indicates that the data signal received by the current paging cycle is unreasonable, and it may directly determine that the scenario is scenario 1, so as to obtain a more reasonable reception gain through the received first signal, so that the received data may be stabilized in a more reasonable range according to the reception gain, and further, a decoding error is avoided from occurring again.

If the fixed duration of the sliding observation window is N paging cycles, the current paging cycle may be understood as the nth paging cycle in the sliding observation window. It is to be understood that since the sliding observation window is a time window sliding in the time domain, the nth paging cycle may be the last paging cycle in the sliding observation window. When the paging cycle enters the sliding observation window, the paging cycle may be processed, that is, the RSRP value and the SINR value are recorded, the paging DCI of the paging cycle is detected, and whether the decoding is correct is determined. If the terminal device detects the paging DCI in the paging cycle and decodes the PDSCH scheduled by the paging DCI incorrectly, it may directly determine that the paging cycle is scene 1.

For example, it is also assumed that the fixed duration of the sliding observation window is 8 paging cycles, when the sliding observation window is full of 8 paging cycles, the 8 th paging cycle in the sliding observation window is the current paging cycle, and if the terminal device detects paging DCI in the 8 th paging cycle and decodes a PDSCH scheduled by the paging DCI incorrectly, it may be determined as scenario 1.

By judging the terminal device as scene 1 when the paging decoding failure rate is greater than the third threshold value or the paging decoding error of the current paging cycle occurs, the first signal can be adopted to determine the receiving gain under the condition that the decoding failure rate is higher or the paging decoding error occurs, so as to improve the paging decoding performance of the terminal device.

In one implementation, the case that the first preset condition is not satisfied may include: the RSRP fluctuation value is less than or equal to a first threshold value, the SINR fluctuation value is less than or equal to a second threshold value, the paging decoding failure rate is less than or equal to a third threshold value, and the terminal equipment detects paging DCI and correctly decodes the PDSCH scheduled by the paging DCI.

When the above four conditions are simultaneously satisfied, it may be considered that the first preset condition is not satisfied, and in this case, it may be determined that the scene 2 is scene 2, that is, the reception gain is determined by the historical reception gain. That is, if any one of the four conditions is not satisfied, it may be determined that the first preset condition is satisfied, that is, it may be determined that the scene 1 is satisfied.

Illustratively, if the terminal device detects the paging DCI in the current paging cycle in the sliding observation window and correctly decodes the PDSCH scheduled by the paging DCI, the RSRP fluctuation value, the SINR fluctuation value, and the paging decoding failure rate in the sliding observation window may be determined again. Under the condition that the RSRP fluctuation value, the SINR fluctuation value, and the paging decoding failure rate do not exceed the corresponding threshold values, it may be determined as scenario 2. Optionally, in the RSRP fluctuation value, the SINR fluctuation value, or the paging decoding failure rate, if any value exceeds the corresponding threshold value, it is determined as scenario 1.

By judging the terminal device as scene 2 under the condition that the first preset condition is not met, the historical receiving gain is adopted to determine the receiving gain under the conditions that the signal fluctuation amplitude is small, the paging decoding failure rate is small, the paging DCI is detected in the current paging cycle, and the PDSCH scheduled by the paging DCI is decoded correctly, so that the energy consumption of the terminal device is reduced.

In one implementation, the receive gain is determined from the first signal if the number of paging cycles within the sliding observation window is less than a preset number. The preset number may be understood as the aforementioned N, where N is a positive integer. In other words, when the fixed duration of the sliding observation window is N paging cycles, if the number of paging cycles in the sliding observation window is less than N, the reception gain is determined by the first signal, that is, it is determined as scene 1.

It can be understood that when the number of paging cycles in the sliding observation window is less than N, the sample data in the sliding observation window may be considered to be insufficient. That is, there is insufficient data to determine whether the fluctuation amplitude of the signal exceeds the threshold value. Therefore, in order to obtain more reasonable reception gain when the sliding observation window is less than N paging cycles, the reception gain can be determined by the first signal. For example, it is also assumed that the fixed duration of the sliding observation window is 8 paging cycles, and if there are 5 paging cycles in the sliding observation window, it may be determined as scenario 1.

When the number of the paging cycles in the sliding observation window is smaller than the preset number, the terminal equipment is judged to be the scene 1, and the first signal can be adopted to determine the receiving gain under the condition that the sample data is insufficient, so that the accuracy of the receiving gain is ensured.

In step S202, the terminal device receives the second signal.

The second signal may be a paging message received by the terminal device through a downlink channel.

It should be noted that, after the terminal device determines the above scenario, since the reception gain is already determined in an appropriate manner, the terminal device may perform corresponding processing on the second signal through the reception gain.

In step S203, the terminal device performs gain control on the second signal according to the reception gain.

Here, performing gain control on the second signal may be understood as amplifying or reducing the second signal according to the reception gain determined in the foregoing step S201.

The terminal device determines the receiving gain according to the different scenes, and performs gain control on the received second signal, so that the signal amplitude of the second signal can be stabilized in a reasonable range, and the energy consumption of the terminal device can be considered while the paging decoding performance of the downlink channel is ensured.

Referring to fig. 4, fig. 4 is a flowchart of another gain control method according to an embodiment of the present disclosure. The gain control method may be implemented by the terminal device, or may be implemented by a chip in the terminal device. As shown in fig. 4, the gain control method includes, but is not limited to, the following steps S401 to S406.

Step S401, the terminal device records the RSRP value and SINR value of each paging cycle, and records the paging decoding result in each paging cycle.

It should be noted that the step S401 described above needs to be executed for each paging cycle.

And step S402, the terminal equipment sets a sliding observation window and judges whether the sliding observation window is full of N paging cycles or not.

If the sliding observation window is not full of N paging cycles, executing step S403; if the sliding observation window is full of N paging cycles, step S404 is executed.

In step S403, scene 1 is determined.

Step S404, the terminal device calculates the value of at least one of the following parameters: RSRP fluctuation value, SINR fluctuation value or paging decoding failure rate.

Step S405, the terminal device determines whether the RSRP fluctuation value is greater than a first threshold, the SINR fluctuation value is greater than a second threshold, the paging decoding failure rate is greater than a third threshold, or whether the PDSCH decoding in the current paging cycle is incorrect.

If the RSRP fluctuation value is greater than the first threshold, or the SINR fluctuation value is greater than the second threshold, or the paging decoding failure rate is greater than the third threshold, or the current paging cycle PDSCH decoding is incorrect, then step S403 is executed; if the RSRP fluctuation value is less than or equal to the first threshold, the SINR fluctuation value is less than or equal to the second threshold, the paging decoding failure rate is less than or equal to the third threshold, and the PDSCH decoding in the current paging cycle is correct, step S406 is executed.

In step S406, it is determined as scene 2.

Specifically, the detailed description and the beneficial effects of the method steps provided in the embodiment of fig. 4 can be referred to the related contents in the embodiment of fig. 2, which are not repeated herein.
