Description

Method and device for testing power saving performance of terminal, network simulator and terminal
Technical Field
The invention relates to the technical field of communication, in particular to a method and a device for testing the power saving performance of a terminal, a network simulator and the terminal.
Background
In the 5G (5th Generation, fifth Generation mobile communication technology) power saving project, a Physical layer designs a new PDCCH _ WU (Physical Downlink Control Channel _ Wake Up) Channel. When a network configures a UE (User Equipment, or called terminal) to operate in a DRX (Discontinuous Reception) state, the previous working process of the UE is as follows: as shown in fig. 1, the UE is in a sleep state during DRX OFF (discontinuous reception OFF) for saving power, but needs to periodically wake up in DRX ON (discontinuous reception ON) state according to network configuration to monitor whether the network calls the UE or waits for the network to schedule the UE to receive transmission data. If the network does not call or schedule the UE to receive and send data, the UE maintains the ON state for a period of time through a timer and then enters the sleep state again.
Since the network does not schedule the UE to receive and transmit data every time the DRX cycle UE wakes up, and the UE wakes up and consumes battery power for a while, a new PDCCH _ WU signal is designed in the physical layer in the power saving project, as shown in fig. 2, a DRX operation process is performed with the PDCCH _ WU signal. The PDCCH _ WU signal is sent by the network some time before the normal DRX ON starts, carrying an Identification (ID) number of the UE that has data to receive. The UE wakes up in advance to receive the PDCCH _ WU signal and solves the UE ID indicated therein, which needs to receive data. When the UE knows that the PDCCH _ WU signal comprises the ID of the PDCCH _ WU signal, the UE wakes up to receive network scheduling for communication during the normal DRX ON period; when the UE knows that the PDCCH _ WU signal does not comprise the ID of the PDCCH _ WU signal, the UE can immediately sleep and does not wake up in the normal DRX ON period, so that the short-time receiving wake-up signal PDCCH _ WU is used for replacing the long-time startup waiting in the DRX ON period, and the purpose of saving electricity is achieved.
However, the PDCCH _ WU signal newly designed in the prior art has no feedback mechanism, that is, the UE does not report feedback to the network for the condition of receiving the PDCCH _ WU signal after receiving the PDCCH _ WU signal. Even whether the UE receives the PDCCH _ WU signal or not is realized by the UE, but the current test method for the performance of receiving the downlink data packet by the UE is not suitable for detecting the performance of receiving the PDCCH _ WU signal by the UE.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
In the standard, the UE quality can be guaranteed only by requiring and testing the signal receiving performance of the UE. In the prior art, the following two test methods are used for testing the data receiving performance of the UE:
test method 1: and (4) UE data feedback method. In the test, a downlink transmission channel is configured, so that the transmission channel meets the test condition, namely a certain channel model and SINR (Signal to Interference plus Noise Ratio), and the UE is configured to receive data of the downlink reference measurement channel. Meanwhile, a good uplink transmission channel (common AWGN (Additive White Gaussian Noise) and high SINR) is configured, so that uplink transmission data almost has no Error code (BLER) (Block Error Rate, or throughput, which is used for receiving downlink data packets by the UE, is obtained by comparing the transmitted data with received data, and then whether the UE meets the requirement is determined.
The test method 2: and the UE receives the state feedback method. In the same test, a downlink transmission channel is configured, so that the transmission channel meets the test condition, namely a certain channel model and SINR, and the UE is configured to receive the data of the downlink reference measurement channel. And simultaneously configuring a good uplink transmission channel (a common AWGN channel, high SINR) to ensure that uplink transmission data have almost no error (BLER is 0). In the test method 2, the performance is judged by the feedback of the UE after receiving the data, that is, the UE feeds back an ACK/NACK signal to the network after receiving the downlink data packet to determine whether the data is normally received. The network simulator carries out statistics on error receiving data blocks through the ACK/NACK signals fed back by the UE, so that the performance (BLER or throughput) of the UE for receiving downlink data packets is obtained, and whether the UE meets the requirements is judged.
However, the newly designed PDCCH _ WU signal has no feedback mechanism, that is, the UE does not report feedback to the network for the case of receiving the PDCCH _ WU signal after receiving the PDCCH _ WU signal. Even whether the UE receives the PDCCH _ WU signal or not is realized by the UE, so the existing test method for the performance of the UE for receiving the downlink data packet is not suitable for detecting the performance of the UE for receiving the PDCCH _ WU signal.
Fig. 3 shows a flowchart of a method for testing power saving performance of a terminal according to this embodiment, where the method includes:
s301, receiving an ACK (ACKnowledgement)/NACK (non-ACKnowledgement) message fed back by the UE, wherein the ACK/NACK message carries a state that the UE receives a downlink data packet sent by a network simulator, and determining the performance of the UE for receiving the downlink data packet sent by the network simulator by counting the ACK/NACK message.
The ACK/NACK message is a feedback message sent by the UE to the network simulator, and the ACK/NACK message carries indication information of the state of the UE receiving the downlink data packet sent by the network simulator.
Specifically, the network simulator configures a downlink data packet to simulate a cell, and the UE accesses the simulated cell and establishes a connection. The network simulator configures the UE in a normal DRX working mode, configures and sends a PDCCH _ WU signal according to a time sequence specified by a specification, and informs the UE that the PDCCH _ WU signal can be used for power saving monitoring.
After the network simulator receives the ACK/NACK message fed back by the UE, the ACK/NACK message is analyzed to obtain the state of the UE, carried in the ACK/NACK message, of receiving the downlink data packet sent by the network simulator, and the performance of the UE of receiving the downlink data packet sent by the network simulator is determined by counting the states of a plurality of ACK/NACK messages.
S302, determining the performance of the UE for receiving the PDCCH _ WU according to the performance of the UE for receiving the downlink data packet.
The network simulator sends a PDCCH _ WU signal before sending the downlink data packet, and the ID of the UE is contained in the ID of the awakened UE in the PDCCH _ WU signal.
Specifically, the network simulator determines the performance of the UE for receiving the PDCCH _ WU according to the performance of the UE for receiving the downlink data packet. Although the UE does not feed back the received PDCCH _ WU signal, the network simulator can test the performance of the UE for monitoring the received PDCCH _ WU signal by determining the performance of the UE for receiving the downlink data packet.
In the embodiment, the network simulator receives the state of the downlink data packet received by the UE carried in the ACK/NACK message fed back by the UE, and determines the performance of the downlink data packet received by the UE, so that the performance of the PDCCH _ WU received by the UE is determined, and the test of the network simulator for monitoring the performance of the PDCCH _ WU signal received by the UE can be realized.
Further, on the basis of the above embodiment of the method, before S301, the method further includes:
and configuring a test condition for the UE to receive the downlink data packet according to a preset mode, and sending the downlink data packet to the UE according to a preset mode under the test condition.
The preset modes are a configuration mode of the quality of the PDCCH _ WU signal received by the UE and a configuration mode of the quality of the PDCCH/PDSCH signal received by the UE.
The test conditions are the values of the quality of the PDCCH _ WU signal received by the UE and the quality of the PDCCH/PDSCH signal received by the UE, which are configured by the network simulator.
The preset mode is a data sending mode of different time selected when the network simulator sends a downlink data packet to the UE, and comprises the following two specific modes:
the first preset mode is as follows: transmitting the downlink data packet to the UE during DRX ON of each DRX period; or the like, or, alternatively,
a second preset mode: and transmitting the downlink data packet to the UE during the DRX ON period of random DRX periods.
Specifically, a data packet to be received by the UE to be tested and a corresponding PDCCH _ WU signal can be configured ON each DRX ON; data packets to be received by the UE under test and corresponding PDCCH _ WU signals can also be randomly configured in certain DRX ON configurations.
Wherein, DRX is a time period configured for UE by a network, and each period comprises a DRX ON period of a starting part and a following DRX OFF period. When the data of the UE exists, the data is sent to the UE during the DRX ON period. If the UE knows that no data needs to be received during the DRX ON period, the UE can be directly powered OFF to enter the DRX OFF state and does not receive the data during the DRX ON period.
By sending the downlink data packet during the DRX ON period of each DRX period, the power consumption of the UE can be saved to the maximum extent; the UE is configured to receive the data packet carried by the PDCCH/PDSCH at the DRX ON randomly, so that possible fraud behaviors of the UE during testing are avoided.
The network simulator can indirectly test the receiving performance of the UE ON the PDCCH _ WU signal by testing the receiving performance of the UE ON the common PDCCH/PDSCH data in the DRX ON.
Further, on the basis of the above method embodiment, configuring, according to a preset manner, the test condition for the UE to receive the downlink data packet specifically includes:
configuring the quality of the PDCCH _ WU signal received by the UE and the quality of the PDCCH/PDSCH signal received by the UE as the lower limit of the performance of the PDCCH _ WU signal received by the UE alone; or the like, or, alternatively,
and configuring the quality of the PDCCH _ WU signal received by the UE to be a lower performance limit of the PDCCH _ WU signal received by the UE alone, and configuring the quality of the PDCCH/PDSCH signal received by the UE to be more than or equal to the lower performance limit of the PDCCH/PUSCH signal received by the UE directly.
Specifically, the test condition for the UE to receive the downlink data packet may be configured in the following two ways:
the first configuration mode is as follows: the quality, SNR, of the PDCCH _ WU signal received by the UE and the normal PDCCH/PDSCH signal is configured to the same value and to a lower limit of performance requiring the UE to receive the PDCCH _ WU signal alone, such as-6 dB.
The second configuration mode: the quality of the PDCCH _ WU signal is configured only at the lower limit of the performance of the UE for receiving the PDCCH _ WU signal alone, and the quality of the PDCCH/PDSCH signal is configured well enough, so that the error rate of the UE for receiving the PDCCH/PDSCH signal is low enough and can be ignored.
By configuring the PDCCH _ WU signal quality and the PDCCH/PDSCH signal quality to be different values, the error rate of the UE for receiving the PDCCH/PDSCH signals is low enough and can be ignored. Thereby directly testing the performance of the UE to receive the PDCCH _ WU signal.
Further, on the basis of the above method embodiment, S302 specifically includes:
when the quality of the PDCCH _ WU signal received by the UE and the quality of the PDCCH/PDSCH signal received by the UE are both configured to be the lower limit of the performance of the PDCCH _ WU signal received by the UE alone, if the block error rate BLER of the PDCCH/PDSCH signal received by the UE is less than or equal to a first preset value, the performance of the PDCCH _ WU signal received by the UE is determined to be qualified;
when the quality of the PDCCH _ WU signal received by the UE is configured to be the lower limit of the performance of the PDCCH _ WU signal received by the UE alone, and the quality of the PDCCH/PDSCH signal received is configured to be greater than or equal to the lower limit of the performance of the PDCCH/PUSCH signal received by the UE directly, if the BLER of the PDCCH/PDSCH signal received by the UE is less than or equal to a second preset value, the performance of the PDCCH _ WU signal received by the UE is determined to be qualified.
Wherein the first preset value is x1+x2–x1·x2The second preset value is x1；
x1A lower limit of performance for the UE to receive PDCCH _ WU signals separately, the UE to receive separatelyBLER of PDCCH _ WU signal is less than or equal to x1；x2The lower limit of the performance of the UE for directly receiving the PDCCH/PUSCH signals is that the BLER of the UE for directly receiving the PDCCH/PUSCH signals is less than or equal to x2。
Specifically, the criterion for determining that the monitored PDCCH _ WU signal performance of the UE under test is qualified may be different according to different downlink packet quality configuration conditions. The requirement for UE to monitor PDCCH _ WU signal independently is that BLER is less than or equal to x1(ii) a The requirement of directly receiving PDCCH/PDSCH signals is that BLER is less than or equal to x2：
When the PDCCH _ WU signal is configured according to the configuration mode and the signal quality condition of the ordinary PDCCH/PDSCH is the same (if the SNR is the boundary condition of-6 dB), in the test, when the performance of the UE for receiving the PDCCH/PDSCH signals reaches BLER ≦ x1+x2–x1·x2) And judging the product to be qualified.
When only the PDCCH _ WU signal is configured in the second configuration mode as a boundary condition (for example, SNR is-6 dB), the UE is determined to be qualified when the PDCCH/PDSCH signal receiving performance reaches BLER ≦ x1 in the test.
Fig. 4 shows a flowchart of a method for testing power saving performance of a terminal according to this embodiment, where the method includes:
s401, feeding back an ACK/NACK message to a network simulator, wherein the ACK/NACK message carries a state that a UE receives a downlink data packet sent by the network simulator, so that the network simulator statistically determines the performance of the UE for receiving the downlink data packet according to the state that the UE receives the downlink data packet, and further determines the performance of the UE for receiving a PDCCH _ WU.
The network simulator sends a PDCCH _ WU signal before sending the downlink data packet, and the ID of the UE is contained in the ID of the awakened UE in the PDCCH _ WU signal.
The ACK/NACK message is a feedback message sent by the UE to the network simulator, and carries indication information of a state in which the UE receives a downlink data packet sent by the network simulator.
Specifically, the UE monitors a PDCCH _ WU signal (whether monitoring is determined by the UE), when a downlink data packet needs to be received, the UE monitors a common PDCCH ON DRX to receive scheduling information, receives the downlink data packet in the PDSCH according to the scheduling information, and feeds back ACK/NACK to the network simulator in a designated uplink resource according to the scheduling information.
In the actual execution process, the network simulator configures a downlink data packet to simulate a cell, and the UE accesses the simulated cell and establishes connection. The network simulator configures the UE in a normal DRX working mode, sends a PDCCH _ WU signal according to a time sequence configuration specified by a specification, informs the UE that the PDCCH _ WU signal can be used for power saving monitoring, and feeds back an ACK/NACK message to the network simulator after the UE receives the PDCCH _ WU signal.
In this embodiment, an ACK/NACK message is fed back to the network simulator, where the ACK/NACK message carries a state of the UE receiving the downlink data packet, so that the UE can determine, according to the state, a performance of the UE receiving the downlink data packet, thereby determining a performance of the UE receiving the PDCCH _ WU, and implementing a test of the network simulator for monitoring, by the UE, the performance of receiving the PDCCH _ WU signal.
Further, on the basis of the above embodiment of the method, before S401, the method further includes:
receiving a PDCCH _ WU signal before the beginning of DRX ON of each DRX cycle under test conditions, and decoding the PDCCH _ WU signal to determine whether the ID of the UE is included in the PDCCH _ WU signal.
The test condition is a condition that the network simulator configures the UE to receive the downlink data packet according to a preset mode.
Specifically, the data transmission modes of different times selected when the network simulator transmits the downlink data packet to the UE include the following two specific modes:
the first preset mode is as follows: transmitting a PDCCH WU signal to the UE during DRX ON of each DRX cycle; or the like, or, alternatively,
a second preset mode: transmitting a PDCCH WU signal to the UE during DRX ON for a random DRX period.
The UE receives a PDCCH _ WU signal before the beginning of DRX ON of each DRX cycle and decodes the PDCCH _ WU signal to determine whether the ID of the UE is included in the PDCCH _ WU signal.
In the embodiment, before the DRX ON of each DRX cycle starts, a PDCCH _ WU signal is received, and whether the PDCCH _ WU signal includes the ID of the UE is determined, so as to determine whether data needs to be received in the next DRX ON period.
Further, ON the basis of the above method embodiment, after receiving a PDCCH _ WU signal before starting DRX ON of each DRX cycle under the test condition, and decoding the PDCCH _ WU signal to determine whether the ID of the UE is included in the PDCCH _ WU signal, the method further includes:
and if the PDCCH _ WU signal is decoded to determine that the ID of the terminal is included in the PDCCH _ WU signal, receiving a downlink data packet in a PDCCH/Physical Downlink Shared Channel (PDSCH) sent by the network simulator during the DRX ON period of a DRX period after the PDCCH _ WU signal.
And if the PDCCH _ WU signal is decoded and the ID of the terminal is not included in the PDCCH _ WU signal, the UE is directly closed, so that the UE enters a DRX OFF state.
Specifically, if the PDCCH _ WU signal is decoded to determine that the ID of the terminal is included in the PDCCH _ WU signal, the UE determines that there is data to be received during the next DRX ON period, and thus needs to maintain an ON state during the next DRX ON period; if the PDCCH _ WU signal is decoded to determine that the PDCCH _ WU signal does not include the ID of the terminal, the UE determines that no data needs to be received in the next DRX ON period, so that the UE does not need to keep an ON state in the next DRX ON period, can be directly powered OFF to enter a DRX OFF state, and does not receive the data in the ON period, thereby saving the power consumption of the UE.
Fig. 5 is a schematic structural diagram illustrating a testing apparatus for power saving performance of a terminal on a network simulator side according to this embodiment, where the apparatus includes: a message receiving module 501 and a performance determining module 502, wherein:
the message receiving module 501 is configured to receive an ACK/NACK message fed back by a terminal UE, where the ACK/NACK message carries a status of a downlink data packet sent by the UE receiving network simulator, and determines, by counting the ACK/NACK message, a performance of the UE receiving the downlink data packet sent by the network simulator;
the performance determining module 502 is configured to determine, according to the performance of the UE receiving the downlink data packet, the performance of the UE receiving a PDCCH _ WU physical downlink control channel wake-up signal;
