Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a User terminal or a User Equipment (UE), and the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network-side device 12 may be a Base Station and/or a core network element, where the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5GNR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), where the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, and it should be noted that the Base Station in the NR system is only taken as an example in the embodiment of the present invention, but the specific type of the Base Station is not limited.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminals 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include base stations of different types (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication link in the wireless communication system may include an Uplink for carrying Uplink (UL) transmission (e.g., from the terminal 11 to the network side device 12) or a Downlink for carrying Downlink (DL) transmission (e.g., from the network side device 12 to the terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

As described in the background art, more new services, new scenes, and new user requirements will appear in the future, and the network needs to further improve the perception capability, and provide the best service quality and experience guarantee for the user according to the user requirements. Therefore, the network side needs to have a corresponding mechanism to adjust in real time after obtaining the QoE information, so as to improve the QoE of the user. The wireless side is an important ring in the QoE, and the embodiment of the QoE can be directly improved by adjusting the scheduling and resource allocation of the access network.

The Medium Access Control (MAC) layer, as an executor of scheduling resource allocation in the Access network, directly affects the end-to-end QoS index and QoE experience. Different from the traditional MAC scheduling, the embodiment of the invention provides a QoE optimization scheme at an MAC layer, and provides a process of actively reporting terminal QoE information to the MAC layer, the MAC layer can select a new scheduling algorithm for scheduling by combining an artificial intelligence mode by using the QoE information of the terminal through the process, and on the other hand, the MAC layer can sense the QoE experience of UE in real time, intervene in advance on the quality degradation of the QoE and the like, and optimize the QoE of the UE.

Specifically, the embodiment of the invention adds the functions of QoE/QoS control, monitoring and recovery on the basis of the existing MAC function.

Specifically, at the MAC layer on the base station side, the QoE/QoS control, monitoring, and recovery functions include at least one of the following:

1) The base station side MAC sends a QoE request MAC Control Element (CE) for requesting the UE to report a measurement result of QoE.

2) And obtaining the QoE information through a QoE report MAC control unit.

3) And the MAC adjusts the dispatching priority and the logical channel priority of the logical channel corresponding to the service of the UE according to the QoE information.

4) And allocating resources for the terminal according to the QoE scheduling request reported by the terminal.

5) After receiving the QoE control unit sent by the terminal, sending a QoE acknowledgement receiving control unit to the terminal, which is used for indicating that the QoE control unit sent by the terminal is successfully received.

At the terminal side MAC layer, the QoE/QoS control, monitoring and recovery functions include at least one of:

1) The terminal detects the QoE quality, triggers the QoE to actively report, and generates the indication information of the QoE state to be stored in the local. The indication information of QoE status may specifically be a QoE score or other quantified information.

2) And generating a QoE report MAC control unit according to a network request or a terminal QoE report requirement.

3) And sending a QoE report MAC control unit according to the uplink authorization information and the uplink data priority. And if the uplink resources are currently transmitted and the uplink resources can carry the transmission of the QoE report MAC control unit, directly transmitting the QoE report MAC control unit.

4) And if no uplink resource bearing QoE report MAC control unit exists currently, the terminal triggers a scheduling request corresponding to the QoE to apply for the uplink resource.

5) Uplink data multiplexing priority. And if the current uplink resource can only meet part of uplink transmission, multiplexing the uplink data according to the priority of data multiplexing.

The classification, priority and corresponding scheduling request of the QoE MAC control element according to the embodiment of the present invention are described below.

A QoE MAC control unit according to an embodiment of the present invention is shown in fig. 2, where a value of a QoE reporting identifier may also be divided into two categories, one category is terminal triggering, which is also referred to as a terminal-triggered QoE reporting MAC CE, as shown in fig. 3; the other is network triggered, also referred to herein as network (base station) triggered QoE reporting MAC CE, as shown in fig. 4. The QoE MAC control elements triggered by the terminal and the network (base station) respectively correspond to different MAC control element identifiers, that is, have different LCID values. For example, when the LCID in fig. 3 indicates that the terminal triggers the QoE to report the MAC CE identity, the value may be 50; the LCID in fig. 3 may take a value of 51 when indicating that the network (base station) triggers QoE to report the MAC CE identifier.

In addition, preferably, in uplink data multiplexing, the priority of the QoE report MAC control element triggered by the terminal is higher than the priority of the QoE report MAC control element triggered by the network in the embodiment of the present invention.

When the uplink resource cannot carry QoE transmission, the terminal may transmit a scheduling request corresponding to the QoE report MAC control element to trigger uplink scheduling. The base station may configure a set of SR configurations for QoE reporting by sending an RRC message, the SR configurations indicating mapped physical layer resources. The terminal sends the QoE report MAC control unit on the physical layer resource, and the base station detects the QoE report MAC control unit on the physical layer resource. After receiving the QoE report MAC control unit sent by the terminal, the base station generates a QoE confirmation MAC control unit and sends the QoE confirmation MAC control unit to the terminal. The terminal can decide whether to retransmit the QoE report MAC control element according to whether the QoE acknowledgement MAC control element is received or not. One format of the QoE acknowledgment MAC control element is shown in fig. 5.

The following describes an interaction flow of QoE information according to an embodiment of the present invention.

Referring to fig. 6, an embodiment of the present invention provides a method for sending QoE information, where when applied to a terminal side, the method includes:

and step 61, the terminal detects the QoE of the first service and generates QoE information of the first service.

Here, the MAC layer of the terminal detects the QoE of the first service and generates QoE information of the first service.

And step 62, the terminal sends the QoE information of the first service to the network through the first MAC CE.

Here, the first MAC CE carries QoE information of the first service. The first MAC CE may specifically be a QoE reporting MAC control element as described above. And the MAC CE identifier of the first MAC CE is used for indicating that the MAC CE is the MAC CE reporting the QoE information. As described above, the first MAC CE may include a terminal-triggered MAC CE and a network-triggered MAC CE, where the terminal-triggered MAC CE is a MAC CE that is actively reported by a terminal, the network-triggered MAC CE is a MAC CE that is reported by the terminal according to a network request, and a priority of the terminal-triggered MAC CE is higher than that of the network-triggered MAC CE.

In addition, in order to distinguish different types of triggering manners, the terminal-triggered MAC CE and the network-triggered MAC CE may have different MAC CE identifications. Of course, the same MAC CE identifier may also be used in the embodiments of the present invention. The MAC CE identity may be represented by the LCID of the preamble.

Through the above steps, the embodiment of the present invention provides a scheme for performing QoE management at the MAC layer from the point of view of QoE optimization, and by introducing QoE management at the MAC layer, a terminal may send QoE information to a network through an MAC control unit, so that the network may directly obtain QoE information of a user, and further perform real-time dynamic adjustment and scheduling according to the QoE information of the user, thereby better performing QoE guarantee. In addition, after the QoE information is obtained, a novel scheduling method can be introduced to optimize QoE representation of the user by adopting an AI-based scheduling algorithm in the MAC. The embodiment of the invention can quickly correct QoE deterioration, really introduces service on-demand processing, and can be more suitable for 6G diversified services.

In a scenario where the QoE triggered by the network reports the MAC CE, before step 61, the terminal may further receive a second MAC CE sent by the network, where the second MAC CE is used to request QoE information of the first service. Then, the terminal performs the step 61 according to the second MAC CE.

In step 62, the terminal determines, according to the uplink grant information, a first uplink resource capable of being used for carrying a first MAC CE, and transmits the first MAC CE by using the first uplink resource. If there is no uplink resource capable of being used for carrying the first MAC CE, the terminal may further send a scheduling request corresponding to the QoE to the network, where the scheduling request is used to request to send the uplink resource of the first MAC CE. Then, the terminal receives configuration information of a second uplink resource allocated by the network in response to the scheduling request, and transmits the first MAC CE by using the second uplink resource.

And when the terminal transmits the first MAC CE by using the first uplink resource or the second uplink resource, the terminal transmits the first MAC CE according to the priority of each MAC CE to be transmitted on the first uplink resource or the second uplink resource and the priority of uplink data. That is, the MAC CE or the uplink data with higher priority will preferentially obtain the uplink resource and be preferentially transmitted.

In the embodiment of the present invention, the network may further indicate, through the MAC control unit (e.g., the third MAC CE), that the first MAC CE has been received to the terminal, and at this time, the terminal receives the third MAC CE sent by the network, so that it can be determined that the network has successfully received the first MAC CE

Fig. 7 is a flow of a method for receiving QoE information, which is applied to a network side device, where the network side device may be a base station in general, as shown in fig. 7, and includes:

step 71, the network side device receives the first MAC CE sent by the terminal.

Here, the first MAC CE carries QoE information of the first service. And the MAC CE identifier of the first MAC CE is used for indicating that the MAC CE is the MAC CE reporting the QoE information. Specifically, the first MAC CE includes a terminal-triggered MAC CE and a network-triggered MAC CE, where the terminal-triggered MAC CE is an MAC CE that is actively reported by the terminal, the network-triggered MAC CE is an MAC CE that is reported by the terminal according to a network request, and a priority of the terminal-triggered MAC CE is higher than that of the network-triggered MAC CE. In addition, the terminal-triggered MAC CE and the network-triggered MAC CE have the same or different MAC CE identities.

Step 72, the network side device obtains QoE information of the first service from the first MAC CE.

Here, the MAC layer of the network device may obtain QoE information of the first service from the first MAC CE sent by the terminal, and then the MAC layer of the network device may adjust scheduling of the first service according to the QoE information of the user, and send updated scheduling information of the first service to the terminal, thereby implementing real-time dynamic scheduling adjustment and better performing QoE guarantee. In addition, after the QoE information is obtained, a novel scheduling method can be introduced to optimize QoE representation of the user by adopting an AI-based scheduling algorithm in the MAC layer. The embodiment of the invention can quickly correct QoE deterioration, really introduces service on-demand processing, and can be more suitable for 6G diversified services.

In this embodiment of the present invention, the network side device may trigger reporting of the QoE information, and at this time, before step 71, the network side device may send a second MAC CE to the terminal, where the second MAC CE is used to request the QoE information of the first service.

In addition, the network side device may also allocate uplink resources for transmitting the QoE information to the terminal according to the request of the terminal. For example, the network side device receives a scheduling request corresponding to the QoE sent by the terminal, then allocates a second uplink resource for transmitting QoE information to the terminal according to the scheduling request, and sends configuration information of the second uplink resource to the terminal. Thus, in step 72, the network side device may receive the first MAC CE on the second uplink resource.

After receiving the first MAC CE, the network side device may further send a third MAC CE to the terminal, where the third MAC CE is used to indicate that the network has received the first MAC CE, so as to complete the confirmation of the reception.

Fig. 8 shows an interaction between the MAC layer of the network side device and the MAC layer of the terminal side device, which includes:

step 81, the terminal MAC layer generates QoE information of the service.

And 82, the terminal MAC layer judges whether the current uplink resource can bear a QoE report, wherein the QoE report carries the QoE information, if so, the step 85 is carried out, and if not, the step 83 is carried out.

And step 83, the terminal MAC layer sends a scheduling request of the QoE report to the network, and requests the network to allocate uplink resources for sending the QoE report.

Step 84, after receiving the scheduling request, the MAC layer of the network side device allocates uplink resources for sending the QoE report to the terminal, sends an uplink scheduling message to the terminal for indicating the allocated uplink resources, and then proceeds to step 85.

In step 85, the MAC layer of the terminal sends a QoE report using the uplink resource, where the QoE report may be a QoE report triggered by the terminal or the network side.

And step 86, after receiving the QoE report, the MAC layer of the network side device replies a MAC CE for indicating successful reception of the QoE report to the terminal.

And 87, the MAC layer of the network side device updates the scheduling information of the service according to the received QoE report, and sends the updated scheduling information to the MAC layer of the terminal, thereby implementing scheduling update of the service.

Through the steps, the embodiment of the invention can respond to the QoE report quickly at the MAC layer, thereby quickly correcting the QoE deterioration and being more suitable for 6G diversified services.
