[0050] In the above embodiment, the terminal reports the first information indicating whether it supports the detection of the first signal, so that the network device can accurately know that the terminal is able to detect the first signal. The network device can then send the first signal to the terminal if the terminal supports the detection of the first signal, thereby ensuring that the terminal can be in better communication conditions to facilitate normal data interaction.

[0051] In conjunction with some embodiments of the first aspect, in some embodiments, the method includes:

[0052] The terminal receives second information sent by the network device, where the second information is used to instruct the terminal to execute at least one set of detection configurations for detecting the first signal.

[0057] In the above embodiment, the terminal can obtain the detection configuration of the network side by receiving the second information, and then achieve more reliable detection of the first signal based on the detection configuration, thereby effectively improving the detection efficiency of the first signal.

[0058] In combination with some embodiments of the first aspect, in some embodiments, the first information is further used to indicate first configuration information expected by the terminal.

[0059] In the above embodiment, the terminal can indicate its desired first configuration information through the first information, so that the network side can configure the detection of the first signal for the terminal based on the configuration expected by the terminal, further ensuring that the terminal can effectively detect the first signal.

[0152] In some embodiments, when network device 102 is provided as a satellite base station, satellite communication with terminal 101 can be achieved. Satellite communication refers to communication performed by terrestrial radio communication equipment using satellites as relays. A satellite communication system consists of a satellite component and a ground component. Characteristics of satellite communication include: a large communication range; communication between any two points within the range of the satellite's radio waves; and low susceptibility to land disasters (high reliability). As a supplement to current terrestrial cellular communication systems, satellite communication can provide the following benefits:

[0153] Extended coverage: For areas that are not covered by current cellular communication systems or are costly to cover, such as oceans, deserts, and remote mountainous areas, satellite communications can be used to solve communication problems.

[0154] Emergency communications: In extreme situations such as disasters such as earthquakes, when cellular communication infrastructure is unavailable, satellite communications can be used to quickly establish communication connections.

[0155] In some embodiments, in satellite communications scenarios, due to the long signal propagation distance between the satellite and the terminal, signal transmission attenuation may be relatively large. Information exchange between the terminal and the base station may be affected. The terminal may experience significant signal fading. For example, at a 30-degree tilt angle, the terminal has an approximately 10% probability of experiencing NLOS transmission in suburban and rural scenarios. In the NLOS scenario, the terminal's signal fading (shadow fading and clutter loss) may be as high as 18dB.

[0450] FIG6A is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG5A , the embodiment of the present disclosure relates to a communication method, which includes:

[0451] Step S6101: The terminal reports its detection capability of detecting a pre-paging signal.

[0452] In some embodiments, the detection capability is used to indicate whether the terminal can support detection of pre-paging signals.

[0453] In some embodiments, the terminal only reports the capability information of whether it supports pre-paging detection. After receiving the capability indication information, the base station determines whether to configure pre-paging information detection for the terminal.

[0454] In some embodiments, the capability information reported by the terminal also indicates the desired detection configuration information. The terminal reports the desired detection configuration information for the pre-paging signal based on its own channel environment. The base station determines a reasonable pre-paging signal detection configuration based on the capability information reported by the terminal.

[0455] In some embodiments, the terminal receives configuration information from the base station or a predefined rule to determine whether to perform pre-paging signal detection and the manner of detecting the pre-paging signal.

[0456] Referring to FIG6B , where the horizontal axis represents the downlink time domain resources of a terminal, in some embodiments, if a terminal does not receive downlink control information from a base station within a predefined or base station-configured time window, the terminal begins detecting for pre-paging signals. The starting position or window length of the time window can be expressed in logical time units, such as slots or subframes, or in absolute time units.

[0457] In some embodiments, if a pre-paging signal is detected, the terminal performs relevant operations to improve its channel conditions, such as moving to an open area or adjusting antenna direction. Optionally, referring to FIG6B , the terminal may further detect paging information. Optionally, data reception may also be performed after detecting the paging signal.

[0458] 6C , in some embodiments, if the terminal does not receive a pre-paging signal, the terminal enters an IDLE state.

[0459] In some embodiments, the terminal receives indication information from the base station and determines to start detecting the pre-paging signal. The indication information may be signaling configured by a higher layer or DCI.

[0460] As shown in FIG6D , in some embodiments, when the indication information is DCI, the terminal detects pre-paging indication information in a predefined or configurable information field in the DCI. For example, when the value of the pre-paging indication field is "1," the terminal determines to start detecting pre-paging indication information; when the value of the pre-paging indication field is "0," the terminal stops detecting pre-paging indication information, i.e., does not perform pre-paging signal detection on subsequent downlink resources.

[0461] In some embodiments, the pre-paging indication field may also indicate detection configuration information, such as shown in the following table:

[0462] In some embodiments, if a pre-paging signal is detected, the terminal performs relevant operations to improve its channel condition, such as moving to an open area or adjusting the antenna direction.

[0463] In some embodiments, the terminal may further detect paging information. If the terminal does not receive the pre-paging signal, the terminal enters the IDLE state.
