Description

Method, apparatus and computer readable storage medium for awareness services Technical Field Exemplary embodiments of the present disclosure relate generally to the field of communications and, more particularly, relate to methods, apparatus, and computer-readable storage media for sensing services, such as for sensing candidate transceiver selection and maintenance. Background With the development of communication technology, future wireless networks such as 6G networks may support an important feature, namely, integrated communication (ISAC) of INTEGRATED SENSING AND. ISACs are expected to provide a wide range of awareness services that may vary greatly from one another in terms of specific awareness operations in the radio access network (radio access network, RAN). But in either ISAC networks or any other aware networks, various techniques related to the aware services or operations may need to be further improved or optimized to enhance the performance of the aware services or operations. Disclosure of Invention In general, exemplary embodiments of the present disclosure provide a scheme for a perception service (e.g., for selecting and maintaining a perception candidate transceiver, transmitter, or receiver). It should be understood that the summary is not intended to identify key or essential features of the embodiments of the disclosure, nor is it intended to be used to limit the scope of the disclosure. Other features of the present disclosure will become apparent from the description that follows. In a first aspect, a method performed by a first device is provided. In the method, a first device sends a first request to a second device, the first request requesting the second device to act as a transceiver, transmitter or receiver for performing a sensing operation targeting at least one of a sensing direction or a sensing region. The first device also receives a first response to the first request from the second device. In this way, the first device can correctly determine that the second device is a transmitter, a receiver or a transceiver according to the request and the response, so as to realize reliable sensing operation aiming at least one of a sensing direction or a sensing area, thereby efficiently and flexibly managing the second device and other devices. In some implementations, the first device also determines the second device based on the perceived map. In this way, the first device may accurately determine the second device based on the perceptual map. In some implementations, the first device also sends a second request for the second device's awareness capability information to the second device. The first device also receives a report from the second device that includes the awareness capability information of the second device. In this way, the first device may obtain capability information from the second device to accurately determine that the second device is to be used for a perception operation targeting at least one of a perception direction or a perception region. In some implementations, the perceptual capability information indicates a capability as at least one of a transceiver, a transmitter, or a receiver. Additionally or alternatively, the perception capability information indicates availability of one or more of a perception timing, a perception duration, at least one perception direction, or at least one perception region. In this way the second device can inform the first device of its own detailed capability information, e.g. as both transmitter and receiver, or as both transmitter and receiver capabilities. The capability information may also be the perceived time, perceived duration, perceived direction, and availability of perceived areas. The capabilities and availability may be combined, for example, as a sender of perceived directions. Through the detailed capability information, the first device can determine the second device more accurately, so that the second device and other devices can be managed efficiently and flexibly. In some implementations, the perceived region includes a set of points having coordinates representing vertices of the perceived region. Additionally or alternatively, the perceived region includes a set of points having a defined shape. In this way, for example, the perceived area can be flexibly implemented in different schemes according to different usage scenarios. In some implementations, the perceptual capability information further includes one or more of coordinates of the second device, a perceived beam pattern of the second device, a Beam Width (BW) of the second device, a beam main lobe direction of the beam, a maximum perceived transmission power of the second device, and a maximum perceived BW available per component carrier of the second device. In this way, the wireless capabilities of the second device may be described in detail and accurately, thereby making the determination at the first device efficient and accur
