Of course, those skilled in the art will appreciate that the various embodiments provided in the embodiments of the disclosure may be implemented separately, may be implemented in combination with the methods of other embodiments of the disclosure, and may be implemented separately or in combination with some methods of other related technologies; the embodiments of the present disclosure are not so limited.

For a better understanding of the embodiments of the present disclosure, the following describes an application scenario of a perceived service:

in order to better understand the technical solution described in any embodiment of the present disclosure, first, an application scenario in the related art is described:

mobile media class services, extended Reality (XR) services such as cloud augmented Reality (AR, augmented Reality) or Virtual Reality (VR), cloud games, video-based machine or drone remote control, etc. are expected to contribute higher and higher traffic to 5G networks.

In addition to audio-visual streams, XR services also involve multi-modal data streams, such as, for example, biosensing data streams. These multimodal data are data describing the same service or application that is input from the same device or from different devices (including sensors) and may be output to one or more destination device terminals. The data streams in multimodal data often have some or even strong correlation, e.g. synchronization of audio and video streams, synchronization of haptic and visual, etc. The data flow of the media service, the data flow and the demand of the service data flow for network transmission have common characteristics, and the effective identification and utilization of the characteristics are more beneficial to the transmission and control of the network and the service guarantee and the user experience.

However, the 5GS system adopts a general QoS mechanism to process various data services including XR service, and the XR media service characteristics are not fully considered, so that differentiated uplink and downlink requirements, such as uplink data reliability and asymmetric requirements of downlink data bandwidth, cannot be effectively supported. Meanwhile, XR media data flow has the characteristics of high bandwidth, low time delay and high reliability, and the energy consumption is outstanding. And energy consumption schemes are also an important factor affecting service usage and user experience.

In one embodiment, various data services including XR services have high throughput, low latency, and high reliability requirements, and the state of the terminal, e.g., heat level, battery power, and processor load, may affect the user experience. High power consumption is required due to high throughput, resulting in high terminal side temperature and processor load. Therefore, from a system perspective, limited radio resources and end-to-end QoS policy control, 5GS should be enhanced to support trade-offs between throughput, latency, reliability and terminal status.

In some embodiments, based on existing UE implementations, various schemes may be applied locally at the UE based on battery power, e.g., when battery power exceeds 80%, a higher screen refresh rate is maintained for all services; when the battery level is below 80%, a medium screen refresh rate is maintained for all services; when the battery level is lower than or lower than 20%, turning off some optional and high-power threads or application programs; when the battery level is below 10%, all non-forced or high power threads or applications are turned off or disabled. However, there is never a concern for reducing the QoS level of certain specific services when the battery is low.

In some embodiments, "UE battery power change" is defined as an access-related policy control request trigger and/or a non-access-related policy control request trigger. The policy control function (PCF, policy Control Function) subscribes to UE battery level changes from the access and mobility management function (AMF, access and Mobility Management Function) or session management function (SMF, session Management Function). Upon receiving the "change UE battery level" event, the PCF determines a policy based on the current UE battery level, e.g., selects a QoS level corresponding to a low or ultra-low battery level for service.

As shown in fig. 2, in this embodiment, there is provided a wireless communication method, wherein the method is performed by a base station, and the method includes:

step 21, according to the terminal state information of the terminal, adopting the QoS grade of the first service corresponding to the terminal state information;

Here, the terminal according to the embodiments of the present disclosure may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensing device, and/or a medical device. In some embodiments, the terminal may be a Redcap terminal or a predetermined version of a new air-interface NR terminal (e.g., an NR terminal of R17).

The base stations referred to in the present disclosure may be various types of base stations, for example, base stations of a third generation mobile communication (3G) network, base stations of a fourth generation mobile communication (4G) network, base stations of a fifth generation mobile communication (5G) network, or other evolved base stations.
