Abstract: A wireless communications method is provided and applied to a communications system using a frequency domain resource with a specified bandwidth. The frequency domain resource is divided into at least two frequency domain resource groups, each frequency domain resource group includes at least one resource block, the at least two frequency domain resource groups belong to a same cell. The method includes: determining, from the at least two frequency domain resource groups, a target frequency domain resource group to be allocated to a target terminal device, where the target frequency domain resource group includes at least one frequency domain resource group; sending first indication information to the target terminal device, where the first indication information is used to indicate the target frequency domain resource group; and performing wireless communication with the target terminal device by using the target frequency domain resource group. Therefore, different user requirements can be flexibly met.

Abstract: Embodiments disclose a radio network information management method and a network device. A radio network information management method is disclosed, where the method includes determining that a user equipment UE exists in a first mobility management unit, and determining radio network information of the first mobility management unit according to measurement statistic information of the UE in the first mobility management unit. It is therefore implemented that a granularity of acquiring and managing radio network information in a cell is per mobility management unit, and for a complex cell coverage environment, difference a neighboring cells between different areas of the cell and difference about interference between different areas of the cell are specified. The embodiments further disclose a network device.

Abstract: The present invention provides a method for switching a working mode on a relay network, a base station, a relay node, and a communications system. A donor eNB (DeNB) sends an RN reconfiguration message to a relay node RN in frequency division duplex FDD mode, so that the RN switches from the FDD mode to a half-duplex frequency division duplex H-FDD mode. The DeNB receives an acknowledgment message sent by the RN in FDD mode. When the DeNB verifies, according to the RN reconfiguration message and the acknowledgement message, that the RN has already started to switch from the FDD mode to the H-FDD mode, the DeNB switches from the FDD mode to the H-FDD mode.

Abstract translation: 本发明提供了一种在中继网络，基站，中继节点和通信系统上切换工作模式的方法。 供体eNB（DeNB）以频分双工FDD模式向中继节点RN发送RN重新配置消息，使得RN从FDD模式切换到半双工频分双工H-FDD模式。 DeNB在FDD模式下接收RN发送的确认消息。 当DeNB根据RN重新配置消息和确认消息验证RN已经开始从FDD模式切换到H-FDD模式时，DeNB从FDD模式切换到H-FDD模式。

Abstract: An optical module unlocking apparatus includes a housing, including a base and a mounting portion connected to one end of the base. The base has an accommodation area for installing a circuit board and an electrical component. The apparatus also includes an unlocking component, including an unlocking arm movably connected to the housing. The unlocking arm has an abutment portion for abutting against an elastomer of a cage, and the unlocking component is configured to push the unlocking arm outward relative to the housing in an insertion direction under an action of external force to separate the abutment portion from the elastomer. The apparatus further includes an elastic component on an outer side surface of the mounting portion and outside the accommodation area. A first end of the elastic component is connected to the mounting portion and a second end of the elastic component is connected to the mounting portion.
