In one embodiment, the first wireless connection is a wireless data connection established between two base stations for transmitting backhaul data.
In step 103, a wireless backhaul is implemented with the core network based on the first wireless connection.
In one embodiment, in steps 102 and 103, the base station with wireless backhaul capability may establish a first wireless connection with the base station with wired backhaul capability through a wireless communication protocol, where the connection is used for implementing wireless backhaul, that is, the base station with wireless backhaul capability sends backhaul data to the base station with wired backhaul capability, and the base station with wired backhaul capability transmits the backhaul data to the core network device through a wired transmission link, such as an optical fiber link.
In an exemplary scenario, as shown in fig. 1C, the wireless backhaul capable base station 10, the wireless backhaul capable base station 20, the wired backhaul capable base station 30, and the core network device 40 are included, wherein the wireless backhaul capable base station 10 can search for the surrounding wired backhaul capable base station 30 after being powered on, the wired backhaul capable base station 30 can establish a wired connection with the core network device 40, if the wired connection is found, the wired backhaul capable base station 30 establishes a first wireless connection with the wired backhaul capable base station 30, and implements a wireless backhaul of the wireless backhaul capable base station 10 based on the first wireless connection, and when the wired backhaul capable base station 30 is not found, the wireless backhaul capable base station can be searched, and when the wireless backhaul capable base station 20 is found, the second wireless connection with the wireless backhaul capable base station 20 is attempted to be established, the base station 20 with wireless backhaul capability may establish a wireless connection with other base stations with wired backhaul capability, so the base station 10 with wireless backhaul capability can implement a wireless backhaul through a second wireless connection with the base station 20 with wireless backhaul capability, and in the process, the base station 10 with wireless backhaul capability may continue to search for the base station with wired backhaul capability and establish a connection with the base station with wired backhaul capability when the base station with wired backhaul capability is searched.

Please refer to the following embodiments for details of how to perform measurement configuration.
The technical solutions provided by the embodiments of the present disclosure are described below with specific embodiments.
Fig. 2 is a flow diagram illustrating yet another method of implementing a wireless backhaul in accordance with an example embodiment; in this embodiment, by using the above method provided by the embodiment of the present disclosure, taking a base station with a wireless backhaul capability to implement wireless backhaul as an example for illustration, as shown in fig. 2, the method includes the following steps:
in step 201, a base station with wired backhaul capability is searched, and step 202 or step 204 is executed.
In step 202, when the wired backhaul capable base station is found, a first wireless connection with the wired backhaul capable base station is established.
In step 203, a wireless backhaul is implemented with the core network based on the first wireless connection, and the procedure ends.
In one embodiment, the description of steps 201-203 can refer to the description of steps 101-103 in the embodiment shown in fig. 1A, and will not be described in detail here.
In step 204, if no base station with wire backhaul capability is found, a base station with wireless backhaul capability is found, and step 205 or step 206 is executed.
In step 205, when no base station with backhaul capability is found, the process switches to the dormant state and ends.
In one embodiment, if neither the base station with wired backhaul capability nor the base station with wireless backhaul capability is found within the predetermined time period, the base station cannot currently implement backhaul and cannot serve the ue, and thus the ue may switch to the sleep state.
In an embodiment, the base station switched to the dormant state may be switched to the awake state after a predetermined time, and continue searching for the base station with the wired backhaul capability, i.e. re-execute step 201.
In step 206, when the base station with wireless backhaul capability is searched, a second wireless connection is established with the base station with wireless backhaul capability, backhaul is attempted through the second wireless connection, and the base station with wired backhaul capability is periodically searched.
In one embodiment, in steps 204 and 206, the base station with wireless backhaul capability may have a plurality of base stations with wireless backhaul capability in the periphery, and when the base station with wired backhaul capability is not found, it may also be possible to implement wireless backhaul by searching other base stations with wireless backhaul capability, for example, when the base station with wireless backhaul capability 11 does not find the base station with wired backhaul capability, it may attempt to establish wireless connection with the found base station with wireless backhaul capability 12, and the base station with wireless backhaul capability 12 may already establish wireless connection with the base station with wireless backhaul capability 13, and then the base station with wireless backhaul capability 11 may implement wireless backhaul with the base station with wireless backhaul capability 13 via the base station with wireless backhaul capability 12. In one embodiment, after the wireless connection is established between the wireless backhaul capable base station 11 and the wireless backhaul capable base station 12, the wireless backhaul may not be realized, and therefore the wireless backhaul capable base station 11 needs to periodically continue searching for the wired backhaul capable base station.
In step 207, after the base station with wired backhaul capability is found, a third wireless connection with the base station with wired backhaul capability is established, and a wireless backhaul with the core network is implemented based on the third wireless connection.
In one embodiment, the first wireless connection, the second wireless connection, and the third wireless connection are all wireless data connections.
In an embodiment, after the third wireless connection between the base stations with wired backhaul capability is established, the second wired connection between the base stations with wired backhaul capability established before and the base stations with wireless backhaul capability may be released to reduce resource occupation.
In this embodiment, when the base station with wireless backhaul capability does not search for the base station with wired backhaul capability, the base station with wireless backhaul capability may continue to search for the base station with wireless backhaul capability, and try to establish a wireless connection with the base station with wireless backhaul capability after the base station with wireless backhaul capability is searched for, and periodically search for the base station with wired backhaul capability, so that the base station with wired backhaul capability may try to implement wireless backhaul when the base station with wired backhaul capability is not searched for; in addition, by periodically searching the base station with wired backhaul capability, backhaul can be preferentially realized by the base station with wired backhaul capability, and wireless backhaul efficiency is ensured.

In one embodiment, if the backhaul capability is a wireless backhaul capability, it is determined that a base station with the wireless backhaul capability is found.
In this embodiment, the base station may broadcast its own base station type based on the system information, and may detect whether there is a base station with wired backhaul capability around based on the monitored broadcast signaling, so as to implement effective transmission of backhaul capability of the base station, thereby facilitating implementation of wireless backhaul of the base station.
