Abstract: A device and method in a wireless communication system, the device including an access determination unit configured to determine an access requirement of a user equipment (UE); and a control unit configured to switch a target small cell of the device from a closed state to an open state based on the access requirement of the UE, and reallocate to the target small cell a new physical cell identifier different from the physical cell identifier used in the closed state. A physical cell identifier can be dynamically allocated in accordance with the open/closed state of the small cell, reducing the burden of cell planning and maintenance cost, and having greater flexibility.

Abstract: A wireless communications system and a method for performing wireless communication in a wireless communications system. The wireless communications system includes: a first base station node; a second base station node; and a wireless communications apparatus, performing communication with the first base station node and the second base station node. The first base station node and the second base station node perform scheduling coordination, to reduce a probability that the wireless communications apparatus sends an uplink signal to the first base station node and the second base station node simultaneously. The system and method can reduce a probability that a wireless communications apparatus sends an uplink signal to a first base station node and a second base station node simultaneously, thereby effectively ensuring uplink/downlink transmission performance.

Abstract: The disclosure relates to an electronic apparatus in a wireless communications system, and a mobility measurement method. The electronic apparatus comprises a communications device and a mobility measurement device. The communication device is configured to separately perform dual-connection communication with two connection nodes by means of different carriers. The mobility measurement device is configured to perform mobility measurement, for determining a connection switching mode, on the connection nodes in the dual connections in a case in which connection service quality of at least one of the current dual connection nodes is lower than a preset level. The mobility measurement device is further configured to determine a reporting mode of a mobility measurement result according to the measurement condition of at least one of the current dual connection nodes.

Abstract: An electronic device including processing circuitry configured to establish a first wireless communication channel with a user equipment (UE). The device also determines whether a second communication channel of at least a predetermined quality exists between the UE and a non co-baseband basestation (BS) while the first communication channel between the UE and the electronics device is maintained. The first communication channel and the second communication channel use different carrier resources.
