This disclosure relates to the field of communication technology, and in particular to message transmission methods/apparatuses/devices and storage medium.
In the communication system, direct communication between user equipment (UE) is achieved by introducing the sidelink (SL) communication manner. Moreover, in order to save the power consumption of SL UE, the discontinuous reception (DRX) of SL is introduced. In other words, the receiving UE only monitors the second-stage sidelink control information (SCI) on the logical channel in the active state. Furthermore, the UE may not directly communicate with the base station, but may communicate with the base station through the relay of another UE. Herein, the UE that is not connected to the base station is called the remote UE, and the UE that provides the relay function is called the relay UE. In addition, the remote UE and the relay UE can communicate through SL unicast.
In related art, the remote UE in the idle state can send a radio resource control (RRC) establishment request message to the relay UE, so that the relay UE forwards the RRC establishment request message to the base station, and forwards an RRC establishment message sent by the base station to the remote UB, thereby completing the connection establishment procedure. Moreover, the remote UE in the inactive state can send an RRC resume request message to the relay UE, so that the relay UE forwards the RRC resume request message to the base station, and forward an RRC resume message sent by the base station to the remote UE, thereby completing the connection resume procedure. Furthermore, when connection failure occurs at the remote UE, the remote UE can send an RRC reestablishment request message to the relay UE, so that the relay UE forwards the RRC reestablishment request message to the base station, and forwards an RRC reestablishment message sent by the base station to the remote UE, thereby completing the connection reestablishment procedure. In addition, the remote UE can also send a system information request message to the relay UE, and receive system information sent by the relay UE.
However, in related art, after the remote UE sends the RRC establishment request/resume request/reestablishment request/system information request message to the relay UE, the remote UE may enter the SL DRX sleep state, and thus be unable to receive the RRC establishment message/resume message/reestablishment message/system information forwarded by the relay UE, thereby causing failure of connection establishment/connection resume/connection reestablishment, or causing transmission of system information to be delayed, and further affecting the stability of SL communication.

The message transmission methods/apparatuses/devices and storage medium according to the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.
In step 201, a first message is sent to a relay UE.
In an embodiment of this disclosure, the first message may include at least one of the following:
Here, in an embodiment of this disclosure, the above-mentioned specific bearer may specifically include at least one of the following:
The above-mentioned specific logical channel may be any kind of logical channel or any several logical channels, and the specific logical channel may be predetermined based on a protocol.
The above-mentioned first RRC message may include at least one of the following:
The above-mentioned first SL RRC message may be a remote UE information message (e.g., the RemoteUJEInformationSidelink message).
Furthermore, the above-mentioned specific request may specifically be a request for requesting specific system information. The specific system information may be any one or several types of system information, and the specific system information may be specified by a protocol. For example, the specific system information may be emergency notification system information (i.e., SIB7/8/9) and/or positioning system information. In addition, for example, when the first RRC message is the above-mentioned system information request message, the first RRC message may carry a specific request.
In step 202, the remote UE enters the active state to monitor SL between the remote UE and the relay UE.
Here, in an embodiment of this disclosure, when the remote UE enters the active state, it can monitor the SL between the remote UE and the relay UE, so that when the relay UE sends data and/or message(s) to the SL, the remote UE can successfully receive the data and/or message(s) sent by the relay UE.
In step 203, in response to receiving a second message, the remote UE stops (or called “exits”) the active state, where the second message is a response message to the first message.
In an embodiment of this disclosure, the second message may be sent by the relay UE to the remote UE.
Moreover, the second message may include at least one of the following:
Here, the above-mentioned specific bearer may specifically include at least one of the following:
The above-mentioned specific logical channel may be any kind of logical channel or any several logical channels, and the specific logical channel may be predetermined based on a protocol.
Furthermore, the above-mentioned second RRC message is a response message to the above-mentioned first RRC message, where the second RRC message may include at least one of the following:
The above-mentioned second SL RRC message may be a response message to the above-mentioned first SL RRC message, where the second SL RRC message may be a Uu message transfer message (e.g., the UuMessage TransferSidelink message).
In addition, the above-mentioned specific configuration may include specific system information. The specific system information may be any one or several types of system information, and the specific system information may be specified by a protocol. For example, the specific system information may be emergency notification system information (i.e., SIB7/8/9) and/or positioning system information. For example, when the second RRC message is the above-mentioned RRC reconfiguration message, the second RRC message may carry a specific configuration.
Furthermore, in an embodiment of this disclosure, when the remote UE stops the active state, the remote UE stops monitoring the SL between the remote UE and the relay UE, thereby saving power consumption.
To sum up, in the message transmission method according to some embodiments of this disclosure, after sending the first message to the relay UE, the remote UE will enter the active state. Subsequently, after receiving the second message sent by the relay UE, the active state will be stopped, where the second message is a response message to the first message. It can be seen that in some embodiments of this disclosure, the active state will be stopped only after the remote UE receives the response message (i.e., the second message) of the relay UE to the first message sent by the remote UE, thereby avoiding the occurrence of “after sending the first message to the relay UE, the remote UE enters the SL DRX sleep state, resulting in the remote UE being unable to receive the response message sent by the relay UE”, and ensuring successful receiving of the response message (i.e., the second message) by the remote UE, so that the connection establishment/connection resume/connection reestablishment procedure(s) can be successfully implemented, the delay in sending system information can be avoided, and the stability of SL communication can be ensured.
For detailed introduction to steps 301-303, the description of forgoing embodiments can be referred to and thus will not be repeated here.
To sum up, in the message transmission method according to some embodiments of this disclosure, after sending the first message to the relay UE, the remote UE will enter the active state. Subsequently, after receiving the second message sent by the relay UE, the active state will be stopped, where the second message is a response message to the first message. It can be seen that in some embodiments of this disclosure, the active state will be stopped only after the remote UE receives the response message (i.e., the second message) of the relay UE to the first message sent by the remote UE, thereby avoiding the occurrence of “after sending the first message to the relay UE, the remote UE enters the SL DRX sleep state, resulting in the remote UE being unable to receive the response message sent by the relay UE”, and ensuring successful receiving of the response message (i.e., the second message) by the remote UE, so that the connection establishment/connection resume/connection reestablishment procedure(s) can be successfully implemented, the delay in sending system information can be avoided, and the stability of SL communication can be ensured.
In an embodiment of this disclosure, after entering the active state, the remote UE will monitor the SL so as to successfully receive the message responding to the first message subsequently sent by the relay UE.
Moreover, it should be noted that after the remote UE sends the first message, the first message is to be transmitted to the relay UE first, so that the relay UE forwards the first message to the base station. The base station parses the first message and, after generating a response message for the first message, sends the response message to the relay UE so as to be forwarded to the remote UE. It can be seen that after the remote UE sends the first message, it will not receive the response message to the first message immediately, but will wait for a period of time before it can receive the response message to the first message. Based on this, in an embodiment of this disclosure, after the remote UE sends the first message, it does not need to enter the active state immediately. Instead, it first sets a period of time based on a timer. When the timer expires, the remote UE delays entering the active state, thereby shortening the time the remote UE is in the active state and saving power. Moreover, in an embodiment of this disclosure, a timing duration of the timer satisfies the following conditions: the timing duration is less than or equal to the round trip time (RTT) of the first message. Therefore, the remote UE delays entering the active state when the timer expires, the response message will not be missed, thereby ensuring that the response message of the first message sent by the relay UE can be successfully received.
Optionally, a retention time of the active state is further determined based on any one of:
Further, in an embodiment of this disclosure, the timing duration of the timer may be configured by the network device to the remote UE. In another embodiment of the disclosure, the timing duration of the timer may also be configured by the relay UE to the remote UE. Here, when the timing duration of the timer is configured by the network device, it can be configured through an RRC message; when the timing duration of the timer is configured by the relay UE, it can be configured through a sidelink RRC message.
In step 404, in response to receiving a second message, the remote UE stops the active state, where the second message is a response message to the first message.
For other detailed introduction to steps 401-404, the description of forgoing embodiments can be referred to and thus will not be repeated here.
To sum up, in the message transmission method according to some embodiments of this disclosure, after sending the first message to the relay UE, the remote UE will enter the active state. Subsequently, after receiving the second message sent by the relay UE, the active state will be stopped, where the second message is a response message to the first message. It can be seen that in some embodiments of this disclosure, the active state will be stopped only after the remote UE receives the response message (i.e., the second message) of the relay UE to the first message sent by the remote UE, thereby avoiding the occurrence of “after sending the first message to the relay UE, the remote UE enters the SL DRX sleep state, resulting in the remote UE being unable to receive the response message sent by the relay UE”, and ensuring successful receiving of the response message (i.e., the second message) by the remote UE, so that the connection establishment/connection resume/connection reestablishment procedure(s) can be successfully implemented, the delay in sending system information can be avoided, and the stability of SL communication can be ensured.
