This application claims the priority of the Chinese patent application 2020103327152 whose filing date is 2020/4/24. This application quotes the full text of the aforementioned Chinese patent application.

Technical field

The present invention relates to the field of communication technology, and in particular to a method, system, electronic device and storage medium for monitoring paging messages.

Background technique

In the fifth-generation mobile communications (The Fifth-Generation mobile communications, 5G) New Radio (NR) system, in the radio resource control (Radio Resource Control, RRC) idle state, the user equipment When sending uplink data or downlink data (User Equipment, UE for short), it needs to switch from the idle state to the connected state. At present, there is a way that the UE can directly send a small amount of uplink data in the idle state. That is, the network configures a dedicated and periodic uplink pre-configured resource (Preconfigure Uplink resource, PUR for short) and the corresponding downlink search space window for the UE. The UE can send uplink data through the PUR, and can monitor the Physical Downlink Control Channel (PDCCH) in the downlink search space window to receive downlink data.

Considering that the propagation delay between the UE and the satellite is too large, after the UE sends the uplink data, it needs to wait for a period of time (that is, the round trip time, RTT) before receiving the feedback from the network. (HARQ-ACK).

When the uplink preconfigured resource (Preconfigure Uplink resource, PUR) transmission mechanism is applied to NTN (Non Terrestrial Network, non-terrestrial communication/satellite communication) scenarios, after the UE uses the PUR to send the uplink data, it needs to wait for a period of time before receiving the network The feedback sent by the terminal (that is, there is at least a time interval not less than RTT between the PUR and the PUR SS window. When there is a PO (Paging occasion, paging moment) between the PUR and the PUR SS window, according to the existing mechanism, the UE After using PUR to send the uplink data, before monitoring the PUR SS Window, you need to wake up to monitor the PO between the PUR and the PUR SS window. There is a certain energy consumption overhead. In addition, in this case, the UE uses the PUR to send the uplink data. Later, due to the need to monitor the PO, the UE cannot enter the sleep state, which increases the energy consumption of the UE. In addition, in the random access process in the NTN scenario, Msg1 and Msg2, Msg3 and Msg4 (4-Step RACH, four-step random Access process) and MsgA and MsgB (2-Step RACH, two-step random access process) have a time interval not less than RTT, and the above similar problems also exist.

Detailed ways

The present invention will be further described by way of examples below, but the present invention is not limited to the scope of the described examples.

Example 1

The monitoring method for paging messages in this embodiment is applied in user equipment, and is applied in NTN scenarios.

In the NR system, a UE in idle/inactive (idle/inactive) state wants to send uplink/downlink data, and it needs to enter the connected state through a random access process before sending uplink/downlink data. This idle/inactive data transmission mechanism will cause RRC signaling overhead and UE energy consumption, and also cause data transmission delay.

In order to reduce the RRC signaling overhead and UE energy consumption caused by the UE sending uplink data in the idle state, in the narrowband Internet of Things (NB-IOT)/enhanced machine type communication (eMTC), an early data transmission is introduced Mechanism (early data transmission, EDT). The essence of this transmission mechanism is that the UE uses the third message (Msg3) to carry uplink data in the process of initiating random access to achieve the purpose of uplink data transmission, so as to prevent the UE from entering the connected state. For uplink data transmission in the idle state, this method effectively reduces RRC signaling overhead and UE energy consumption, and at the same time reduces UE energy consumption. However, due to the limited number of bits that Msg3 can carry, this method can only upload some small uplink data packets.

In order to enable the UE to transmit larger data packets in the idle state, the existing NB-IOT/eMTC mechanism is that the network configures dedicated periodic uplink pre-configured resources for the UE and the corresponding downlink search space window PURSS Window, the UE The uplink data can be sent through the uplink pre-configured resources, and then the ACK/fallback indication or retransmission scheduling information can be received through the corresponding downlink search space window. Among them, the fallback indicator is used to instruct the UE to fall back to RACH/EDT for data transmission. The network can control the effectiveness of PUR resources through the fallback indicator, that is, when the network uplink resources are tight, the network can instruct the UE to fall back to The way of RACH/EDT carries on the data transmission. The UE can directly send uplink data on the uplink pre-configured resources, thereby preventing the UE from initiating random access to enter the connected state process. The UE can use the PUR to send data only when the TA (Timing Advance, TA) is valid (that is, the uplink synchronization is valid).

In addition, in the PUR transmission mechanism, when the UE uses PUR to send uplink data and the uplink data is correctly received by the base station, the network can consider the UE to be a temporarily connected UE. If the network has indication information (paging/system The information update indication) needs to be sent to the UE, and the UE can be notified through downlink data or signaling (instead of a paging message), that is, if the UE uses the PUR to send the uplink data and is correctly received by the base station, the UE can monitor the corresponding PUR SS Window obtains the instruction information of the network end (if the network end has instruction information that needs to be sent to the UE).

In NTN satellite communication, due to the high altitude of the satellite (for example, a synchronous satellite: 35786Km), the channel propagation delay is relatively large. For example, in a synchronous satellite scenario, the round-trip propagation delay RTT between the UE and the satellite is 270.73 ms. Due to the large propagation delay, there is a large time interval (that is, the time of one RTT) between the PUR and the corresponding HARQ-ACK reception.

As shown in Figure 1, the method for monitoring paging messages in this embodiment includes:

S101. Use uplink pre-configured resources to send uplink data; wherein, the uplink pre-configured resources correspond to a downlink search space window;

S102: Determine not to monitor the paging moment between the uplink pre-configured resource and the downlink search space window, and monitor the physical downlink control channel in the downlink search space window to obtain a paging message fed back by the network according to the uplink data. Among them, the first setting duration is configured by using RRC signaling or configured by using system information.

In this embodiment, after the UE uses the PUR to send uplink data, the UE does not need to monitor the PO between the PUR and the PUR SS Window, but directly monitors the physical downlink control channel in the downlink search space window. At this time, the user equipment does not need to send uplink data. The monitoring state is maintained after the data, thereby effectively saving the power consumption caused by monitoring the PO and saving the energy consumption of the UE.

Example 2

The monitoring method for paging messages in this embodiment is a further improvement of Embodiment 1. Specifically:

As shown in Figure 2, after step S101, the method further includes:

S103. Monitor the first paging moment before the downlink search space window and the time interval is less than the first set duration to obtain a paging message.

Before step S101, it also includes:

The first monitoring mode correspondingly indicates to monitor the paging moment between the uplink pre-configured resource and the downlink search space window;

The second monitoring mode correspondingly indicates not to monitor the paging moment between the uplink pre-configured resource and the downlink search space window, that is, step S102 is executed at this time.

Wherein, the first indication parameter is configured using RRC signaling or configured using system information, that is, whether the monitoring mode of the PO at the paging moment is required is determined through the indication parameter.

The monitoring method of this embodiment further includes:

Determine the first target monitoring mode according to the pre-configured first indication parameter;

Wherein, the first target monitoring mode is the first monitoring mode or the second monitoring mode. or,

In addition, when it is in an eDRX scene, it is determined to perform the first monitoring mode, and when it is in a non-eDRX scene, it is determined to perform the second monitoring mode.

Among them, the role of the Paging message (paging message) includes: (1) Send a call request to the UE in the RRC_IDLE state; (2) Notify the UE in the RRC_IDLE/INACTIVE and RRC_CONNECTED state that the system information has changed; (3) Earthquake Tsunami notification, instructs the UE to start receiving ETWS (earthquake and tsunami warning system) primary notifications and/or ETWS secondary notifications; instructs the UE to start receiving CMAS notifications.

If a terminal (i.e. user equipment) is paged or system information is updated, or an earthquake or tsunami occurs, the base station (i.e., network) first sends a wake-up signal. After the terminal detects the wake-up signal, it monitors the paged PDCCH and receives the page. Call the message, otherwise the terminal has been kept in sleep state in order to achieve the purpose of power saving.

In the eDRX scenario, in each eDRX cycle, there is a paging time window PTW (Paging Time Window), and the terminal monitors paging according to the DRX cycle in the PTW (the DRX cycle time is short, it can be considered that the terminal does not sleep and is always reachable) Channel in order to receive downlink data, the rest of the time the terminal is in a dormant state. At present, a wake-up signal (wake up signal, WUS) is introduced in NR, that is, WUS based on PDCCH, which is essentially DCI Format 2_6 (downlink control information variable). WUS is located in front of the PO, and the UE can determine the monitoring timing of WUS through the location of the PO.

The following is a specific description with examples:

(1) By default, after the UE uses uplink pre-configured resources to send uplink data, it directly determines that the UE does not monitor the paging moment between the uplink pre-configured resources and the downlink search space window, and monitors the physical in the downlink search space window. Downlink control channel to obtain the paging message fed back by the network according to the uplink data;

If the wake-up signal is configured in the UE, the UE does not monitor the WUS associated with these paging moments.

(2) When the indicator parameter X (that is, the upper layer parameter) indicating the monitoring mode is configured:

When X=1, after the UE uses the uplink pre-configured resource to send uplink data, the UE does not monitor the paging moment between the uplink pre-configured resource and the downlink search space window, and monitors the physical downlink control channel in the downlink search space window , To obtain the paging message fed back by the network according to the uplink data;

When X=0, monitor the paging moment between the uplink pre-configured resource and the downlink search space window according to the existing setting.

(3) When in the eDRX scene, monitor the paging moment between the uplink pre-configured resource and the downlink search space window according to the existing setting.

When in a non-eDRX scenario, the UE does not monitor the paging moment between the uplink pre-configured resource and the downlink search space window, and monitors the physical downlink control channel in the downlink search space window to obtain the paging feedback from the network according to the uplink data information;

(4) As shown in Figure 3, after the UE uses uplink pre-configured resources to send uplink data, it directly determines to monitor the first paging moment PO before the downlink search space window and the time interval is less than the first set duration N1, To obtain the paging message ("×" sign indicates that no monitoring is performed on the paging time PO).

Among them, only listen to the first paging moment PO before the downlink search space window and the time interval is less than the first set duration N1. N is configured by high-level signaling, and its unit can be ms, subframe, time slot or symbol .

In this embodiment, after the UE uses the PUR to send uplink data, the UE does not need to monitor the PO between the PUR and the PUR SS Window or only monitors the specific PO between the PUR and the PUR SS Window, thereby effectively saving the monitoring of the PO. The power consumption of the UE saves the energy consumption of the UE.

Example 3

In the 4-step RACH Procedure (four-step random access procedure):

The UE first completes downlink synchronization by reading MIB (Main System Information Block) and SIB1 (System Information Block). The UE reads the SIB1 to determine the resource for sending the preamble (i.e., the first message Msg1) to the network to indicate its intention to access the network. If the network receives the Msg1 correctly, the network will send a random access response message (ie, the second Msg2) scrambled with RA-RNTI to the UE. After sending Msg1, the UE can use RA-RNTI to monitor Msg2 from the network to descramble the message. RA-RNTI is calculated through RO time and frequency resources. Msg2 may include TA, TC-RNTI, power adjustment, and resource indication for UE to send Mgs3. Then, the UE sends its identity and initial access establishment (Msg3) to the network through the uplink scheduling indication in Msg2. Finally, the network can notify the UE of the completion of the initial access process through Msg4, otherwise, the UE can determine that the initial access process has failed.

As shown in Figure 4, in the 4-step RACH Procedure, the method for monitoring paging messages in this embodiment includes:

S201: After sending the first message Msg1, determine not to monitor the paging moment between the first message Msg1 and the second message Msg2, and monitor the second message Msg2;

After sending the third message Msg3, it is determined not to monitor the third paging moment between the third message Msg3 and the fourth message Msg4, and monitor the fourth message Msg4. or,

After sending the first message Msg1, monitor the second paging moment before the second message Msg2 and the time interval is less than the second set duration;

In this embodiment, in the random access process, after the UE sends Msg1 (Msg3), the UE does not need to monitor the PO between Msg1 and Msg2 (the PO between Msg3 and Msg4) or only monitor Msg2 (Msg4) before and The POs with an interval less than N effectively save the power consumption caused by monitoring the POs and save the energy consumption of the UE.

Example 4

The monitoring method for paging messages in this embodiment is a further improvement of Embodiment 3. Specifically:

In the 2-step RACH Procedure (four-step random access procedure):

In order to further reduce the delay of random access, a two-step random access process is currently introduced. In the two-step random access process, the UE completes random access by sending MsgA (including Msg1 and Msg3) and receiving MsgB (including Msg2 and Msg4). Access process.

As shown in Figure 5, in the 2-step RACH Procedure, the paging message monitoring method in this embodiment includes:

S202: After sending the fifth message MsgA, determine not to monitor the fourth paging moment between the fifth message MsgA and the sixth message MsgB, and monitor the sixth message MsgB; or,

After sending the fifth message MsgA, monitor the fourth paging moment before the sixth message MsgB and the time interval is less than the second set duration.

Before step S201 or step S202, the method further includes:

Pre-configure the second indication parameter of the monitoring mode;

Wherein, when the second indicator parameter is the third value, the third monitoring mode is executed;

When the second indicator parameter is the fourth value, execute the fourth monitoring mode;

The third monitoring mode correspondingly indicates to monitor the paging moments between the first message Msg1 and the second message Msg2, the third message Msg3 and the fourth message Msg4, and the fifth message MsgA and the sixth message MsgB;

The fourth monitoring mode correspondingly indicates not to monitor the paging moments between the first message Msg1 and the second message Msg2, the third message Msg3 and the fourth message Msg4, and the fifth message MsgA and the sixth message MsgB.

Wherein, the second indication parameter and the second set duration are configured using RRC signaling or configured using system information.

The monitoring method of this embodiment further includes:

Determine the second target monitoring mode according to the pre-configured second indication parameter;

Wherein, the second target monitoring mode is the third monitoring mode or the fourth monitoring mode. or,

In addition, when it is in the eDRX scene, it is determined to execute the third monitoring mode;

When it is in a non-eDRX scene, it is determined to execute the fourth monitoring mode.

The following is a specific description with examples:

(1) By default, when the UE sends Msg1 (Msg3), the UE does not need to monitor the PO between Msg1 and Msg2 (the PO between Msg3 and Msg4), and directly monitors Msg2 (Msg4);

After the UE sends MsgA, the UE does not need to monitor the PO between MsgA and MsgB, and directly monitors MsgB;

When X=1, after the UE sends Msg1 (Msg3), the UE does not need to monitor the PO between Msg1 and Msg2 (the PO between Msg3 and Msg4), and directly monitors Msg2 (Msg4);

When X=0, the paging time PO between Msg1 and Msg2 and the paging time PO between Msg3 and Msg4 are monitored according to the existing setting method.

(3) When in the eDRX scene, monitor the paging time PO between Msg1 and Msg2 and the paging time PO between Msg3 and Msg4 according to the existing setting method.

When in a non-eDRX scene, the UE does not need to monitor the PO between Msg1 and Msg2 (the PO between Msg3 and Msg4), and directly monitors Msg2 (Msg4);

(4) After the UE sends Msg1 (Msg3), as shown in Figure 6, the UE only needs to monitor the PO that corresponds to Msg2 and has a time interval N2 less than N from Msg2 (PO that has an interval less than N from the corresponding Msg4). Among them, N is configured by high-level signaling, and its unit can be ms, subframe, time slot or symbol ("×" sign indicates that the paging moment PO is not monitored, the same below).

After the UE sends the MsgA, as shown in Figure 7, the UE only needs to monitor the PO that corresponds to the MsgB and the time interval with the MsgB is less than N2.

In this embodiment, in the random access process, after the UE sends Msg1 (Msg3), the UE does not need to monitor the PO between Msg1 and Msg2 (the PO between Msg3 and Msg4) or only monitor Msg2 (Msg4) before and POs with an interval less than N; after the UE sends MsgA, the UE does not need to monitor the PO between MsgA and MsgB or only monitors the PO before MsgB and the interval is less than N, which effectively saves the power consumption caused by monitoring the PO and saves This reduces the energy consumption of the UE.
