In the embodiment, a determination method of a base station to be camped is disclosed, which realizes determination of the base station to be camped by comprehensively considering the duplex capability of the base station and the signal quality of the base station, and avoids that user equipment is camped on the base station supporting the full duplex capability with very poor signal quality.
Please refer to the following embodiments, particularly how to implement full duplex transmission in a cellular network.
The technical solutions provided by the embodiments of the present disclosure are described below with specific embodiments.
Fig. 2 is a flow chart illustrating a method of implementing full duplex transmission in yet another cellular network in accordance with an example embodiment; in this embodiment, the above method provided by the embodiment of the present disclosure is exemplarily described by taking an example that the user equipment determines the base station to be camped on based on the duplex capability of the base station, as shown in fig. 2, including the following steps:
in step 201, a broadcast signaling carrying duplex capability indication information sent by a base station is received.
In step 202, when selecting the base station for camping, the difference between the signal reception quality of the base station with the strongest signal and having full duplex capability is calculated.
In one embodiment, when the ue needs to select a base station to camp on, the duplexing capability and the signal reception quality of each base station may be determined, and the difference between the signal reception quality of the strongest base station with full duplexing capability and the signal reception quality of the strongest base station with full duplexing capability is calculated, for example, the signal reception quality of the strongest base station with full duplexing capability is-45 dB, and the signal reception quality of the strongest base station with full duplexing capability is-75 dB, and the difference is 30 dB.
In step 203, it is determined whether the difference is greater than a preset intensity threshold, and if not, step 204 is performed, and if so, step 205 is performed.
In one embodiment, the predetermined strength threshold may be a system-agreed value, for example, 20dB, and if the difference between the signal reception quality of the strongest signal base station and the signal reception quality of the strongest signal base station with full-duplex capability is greater than the predetermined strength threshold, it may indicate that the signal reception quality of the strongest signal base station with full-duplex capability is too poor.
In step 204, the base station with full duplex capability is determined as the base station to camp on, and step 206 is executed.
In an embodiment, since the difference between the signal reception quality of the strongest signal base station and the signal reception quality of the strongest signal base station with full-duplex capability is not greater than the preset strength threshold, it can be understood that the signal reception quality of the strongest signal base station with full-duplex capability is not very poor, and therefore the strongest signal base station with full-duplex capability can be determined as the base station to be camped on.
In step 205, the base station with the strongest signal is determined as the base station to be camped on, and step 206 is executed.
In an embodiment, since the difference between the signal reception quality of the strongest signal base station and the signal reception quality of the strongest signal base station with full-duplex capability is greater than the preset strength threshold, it can be understood that the signal reception quality of the strongest signal base station with full-duplex capability is very poor, and therefore the strongest signal base station can be determined as the base station to be camped on.
In step 206, a cell camping operation of camping on the base station to be camped is performed.
In the embodiment, the base station to be resided is determined by comprehensively considering the duplex capability of the base station and the signal quality of the base station, and the situation that the user equipment resides in the base station which has poor signal quality and supports the full duplex capability is avoided.
Fig. 3 is a flow chart illustrating a method of implementing full duplex transmission in a cellular network in accordance with an example embodiment; the method for implementing full duplex transmission in the cellular network can be applied to a base station, as shown in fig. 3, the method for implementing full duplex transmission in the cellular network includes the following steps 301-302:
in step 301, the base station generates broadcast signaling carrying duplex capability indication information.
In an embodiment, the duplex capability indication information indicates a duplex capability of the base station, and the duplex capability of the base station is a full duplex capability or a half duplex capability.
In one embodiment, the broadcast signaling is a dedicated signaling for indicating that the base station has full duplex capability, and in one embodiment, the broadcast signaling can also be a minimum system signaling, such as a system signaling including cell selection and access related information; alternatively, the broadcast signaling may be other than the minimum system signaling, such as system information block12 (systemlnformationblock 12, abbreviated as SIB12) signaling.
In step 302, the base station transmits broadcast signaling.
In an exemplary scenario, as shown in fig. 1B, in the scenario shown in fig. 1B, the base station 10 may broadcast a broadcast signaling carrying duplex capability indication information, and after monitoring the broadcast signaling, the ue 20 may select a suitable base station for camping based on the broadcast signaling.
Through the above steps 301 to 302, the present embodiment can solve the problem that the related art does not provide a solution for introducing the full duplex technology into the cellular wireless network, improve the data transmission performance between the base station with full duplex capability and the user equipment with full duplex capability, and realize that the base station can efficiently transmit its own full duplex capability.
In an embodiment, the duplex capability indication information indicates a duplex capability of the base station, the duplex capability of the base station being a full duplex capability or a half duplex capability.
In an embodiment, the method further comprises:
acquiring the duplex capability of user equipment;
and when the duplex capability is the full duplex capability and the trigger condition is met, starting a full duplex transmission mode between the user equipment and the user equipment.
In this embodiment, a trigger mode for a base station to start a full duplex transmission mode is disclosed, and by triggering the full duplex transmission mode, data transmission performance between the base station with full duplex capability and a user equipment with full duplex capability can be improved.
In one embodiment, acquiring the duplex capability of the user equipment comprises:
sending a capability request signaling to user equipment to be accessed or accessed;
and receiving duplex capability returned by the user equipment.
Please refer to the following embodiments for details of how to implement full duplex transmission.

In an embodiment, the duplex capability of the user equipment can be acquired by sending the capability request signaling to the user equipment to be accessed or accessed, and the duplex capability returned by the user equipment can be monitored after the capability request signaling is sent to the user equipment.
In an embodiment, after receiving the duplex capability of the user equipment reported by the user equipment based on the system agreed mode, the base station may locally store the duplex capability of the user equipment.
In an embodiment, the duplex capability of the UE may be one piece of information in the UE capability, and the base station may resolve the duplex capability of the UE in the UE capability.
In step 402, when the duplex capability is the full duplex capability and the trigger condition is satisfied, the full duplex transmission mode with the user equipment is started.
In an embodiment, the trigger condition may include one or more of the following: the service quality of the service data to be transmitted of the user equipment is higher than a preset quality threshold, the data buffer amount of the service data to be transmitted of the user equipment is larger than a preset buffer value, and uplink and downlink crosstalk and the like cannot be caused in a full-duplex transmission mode between the base station and the user equipment.
