Alternatively, the target time period may be 25 milliseconds.

S103, the terminal analyzes the target signal to obtain a signal identifier of the target signal.

Wherein, the signal identification of the target signal has a corresponding relation with the signal type of the target signal.

It should be understood that after the terminal receives the target signal, the terminal may perform parsing on the target signal to obtain a signal identifier of the target signal, and then determine a signal type of the target signal according to the corresponding relationship.

In an alternative implementation manner, after receiving the target signal, the terminal may determine whether the target signal is accessible, and if the target signal cannot be accessed, analyze the target signal to obtain the signal identifier of the target signal.

And S104, under the condition that the signal type of the target signal is a detection signal and the terminal has no network access, the terminal sends a feedback signal to the network equipment.

Wherein, the feedback signal includes the position information of the terminal.

It should be understood that the network device may not provide communication services to the area where the terminal is located, or the communication services in the area where the terminal is located are poor, resulting in the terminal having no network access, where the terminal may determine that the terminal needs the network device to provide communication services.

It should be understood that, in the case that the signal type of the target signal is a detection signal, the detection signal is used to detect whether a terminal exists in a signal coverage area, and the detection signal cannot provide a communication service for the terminal, where the terminal may send a feedback signal to the network device.

It will be appreciated that the feedback signal is used to inform the area that a terminal is present and that the terminal has no network access.

It should be understood that, in the case where the terminal determines that the signal type of the target signal is a detection signal and the terminal has no network access, the feedback signal may be transmitted at a location where the terminal receives the target signal, and thus, location information of the terminal may be included in the feedback signal.

Optionally, the location information of the terminal may also be the direction in which the terminal is located, and the network device may determine the direction of the terminal according to the source of the feedback signal.

In an alternative implementation, the feedback signal may be the current uplink common signal, such as a physical random access channel (pysical random access channel, PRACH), or may be a newly designed common signal.

Optionally, the feedback signal may also include an identifier of the feedback signal, where the identifier may be a code identifier, or a system message.

And S105, under the condition that the network equipment receives the signal to be identified sent by the terminal, analyzing the signal to be identified to obtain the signal identification of the signal to be identified and the position information of the terminal.

The signal identification of the signal to be identified has a corresponding relation with the signal type of the signal to be identified, and the power identification signal is a signal sent to the network equipment by the terminal after receiving the detection signal.

And S106, the network equipment determines to improve the communication service to the target area under the condition that the signal type of the signal to be identified is a feedback signal.

The target area is an area corresponding to the position information of the terminal.

It can be understood that, when the signal type of the signal to be identified is a feedback signal, it is indicated that the signal to be identified is a signal sent to the network device after the terminal receives the detection signal sent by the network device, and at this time, the network device may determine that the terminal exists in the area where the location information of the terminal is located, and the terminal has no network access.

It should be understood that since the location information of the terminal exists in the terminal, the network device may determine to enhance the communication service to the area corresponding to the location information of the terminal.

Specifically, the network device may send an access signal to the target area, so that the terminal may receive the access signal and perform communication based on the access signal.

Optionally, the network device may also direct a traffic beam to the target area, thereby providing communication services to the target area.

In an alternative implementation manner, the network device may further agree with the terminal on the identity of the feedback signal in advance, and then the network device stores a correspondence between the identity of the feedback signal and the identity of the detection signal, where the network device may determine that the signal type of the target signal is the feedback signal when the identity of the target signal is the same as the identity corresponding to the identity of the detection signal stored in the network device.

Optionally, after the network device receives the feedback signal sent by the terminal, the direction of the source of the feedback signal may be determined, and then, based on the direction of the source of the feedback signal, it is determined to increase the communication service towards the direction.

Wherein the access signal is used for providing communication services for the terminal.

It will be appreciated that after receiving the access signal sent by the network device, the terminal may access the access signal and then communicate based on the access signal.

In an implementation manner of the embodiment of the present application, the network device may send, to an area outside the coverage area of the cell corresponding to the network device, the detection signal based on the beam in the coverage area of the non-cell, where the detection signal is used to detect whether there is a terminal in the area outside the coverage area of the multiple cells, and after the network device receives the feedback signal sent by the terminal in the coverage area of the non-cell, improve the communication service to the area in the coverage area of the non-cell.

In the application, because the feedback signal includes the location information of the terminal, the network device can determine the target area based on the feedback signal, and because the feedback signal is sent by the terminal when the detection signal is received and the terminal has no network access, the network device can determine that the target area exists in the terminal, and the terminal in the target area has no network service, and the network device provides communication service for the target area when the terminal exists in the target area and the terminal in the target area has no network access, can provide network service for the terminal having no network service, improves the communication experience of users, and improves the flexibility of coverage of the access signal.

Referring to fig. 3, as shown in fig. 5, the communication method provided in the embodiment of the present application further includes S108 to S109.

And S108, in the case that the signal type of the signal to be identified is other signals, the network equipment determines whether the signal strength of the other signals is greater than or equal to a signal strength threshold value.

Wherein the other signal does not include an identification of the feedback signal.

It should be appreciated that in the case where the signal type of the signal to be identified is other signals, the network device may determine the signal strength of the signal to be identified.

It will be appreciated that when the identification of the feedback signal is not included in the signal to be identified, the network device may determine that the signal to be identified is another signal.

It is understood that the network device stores basic noise in a communication environment, and the signal strength threshold may be understood as a signal strength of the basic noise.

And S109, in the case that the signal strength of the signal to be identified is greater than or equal to the signal strength threshold, the network equipment determines to improve the communication service to the target area.

It should be understood that, when the signal strength of the signal to be identified is greater than or equal to the signal strength threshold, it is indicated that the signal strength in the direction corresponding to the signal to be identified is abnormal, and there may be a terminal in the direction corresponding to the signal to be identified, where the network device may also determine to provide the communication service to the target area.

Optionally, if the signal strength of the signal to be identified is smaller than the signal strength threshold, it is indicated that the signal strength of the signal to be identified is weaker, possibly the signal to be identified is some noise interference, or the terminal is far away from the network device, at this time, the terminal cannot receive the access signal sent by the network device, and the network device may determine not to provide the communication service to the target area.

In an optional implementation manner, after receiving the signal to be identified, the network device may not analyze the signal to be identified due to weaker signal strength of the signal to be identified, and at this time, the network device may directly determine whether the signal strength of the signal to be identified is greater than or equal to a signal strength threshold without analyzing the signal to be identified, and provide a communication service to the target area under the condition that the signal strength of the signal to be identified is greater than or equal to the signal strength threshold.

Optionally, the network device may determine the target area based on a direction of a source of the signal to be identified without parsing the signal to be identified by the network device.

Referring to fig. 3, as shown in fig. 6, the first time-frequency location is a time-frequency location corresponding to the detection signal in the plurality of time-frequency locations, and the network device provides a communication service to the target area, which may specifically include S1061.

The access signal is used for providing communication service for the terminal, and the second time-frequency position is a time-frequency position except the first time-frequency position in the plurality of time-frequency positions.

It should be understood that each common signal corresponds to a time-frequency location, and the network device may select an unoccupied time-frequency location to send the detection signal.

It can be understood that, since the first time-frequency location is a time-frequency location corresponding to the detection signal in the plurality of time-frequency locations, the network device may send the access signal to the target area at other time-frequency locations other than the first time-frequency location, that is, the second time-frequency location.

In an alternative implementation, the network device may delay the first time period after the time-frequency location of the occupied common signal to determine the first time-frequency location or the second time-frequency location.

In another alternative implementation, the network device may involve a new common signal and determine it as a detected signal, and then represent different time-frequency domain locations by different cyclic shifts.

It should be appreciated that SSB is a signal that is made up of three parts PSS, SSS, PBCH together, and the network device may determine one of the SSB, PSS, SSS as the common signal, or may combine one or more of the SSB, PSS, SSS to generate the common signal.

It is understood that the predetermined byte is an identification of the detection signal.

Alternatively, the preset byte may be some system messages.

Optionally, the common signal is a special initial value for the network device, the sequence generation mode of multiplexing access, the generated special PSS sequence, and then the network device may generate the detection signal based on the special PSS sequence and the preset byte.
