Abstract: Disclosed are a method and apparatus for sending information and channel monitoring processing. The method comprises: when a terminal receives a wake-up signal and is woken up, monitoring, within a time window, a paging channel and/or a control channel in a discontinuous reception or an extended discontinuous reception manner; if the terminal receives a paging message and/or control channel scheduling information within the time window, then processing the paging message and/or processing the control channel scheduling information; and if the terminal does not receive a paging message and/or control channel scheduling information within the time window, then not monitoring the paging channel and/or control channel any more, and continuing to receive a wake-up signal. A base station sends the wake-up signal to the terminal, and sends, within a time window, information over a paging channel and/or a control channel in a discontinuous reception or an extended discontinuous reception manner. By means of the present application, it can be ensured that a terminal saves electricity, and that a service of the terminal can be reached.

Abstract: The embodiments of the present application relates to the technical field of wireless communications, in particular to a method and device for sending and receiving feedback, used for resolving the problems existing in the prior art that, at present, it cannot be determined whether the UE successfully receives a PDCCH command after the eNodeB sends same. In the embodiments of the present application, after receiving a PDCCH command from a network side device, a terminal sends, by means of a BSR MAC control unit or a MAC control unit in a MAC PDU, feedback information of the PDCCH command being successfully received to the network side device, thereby informing the network side device of successfully receiving the PDCCH command, such that the eNodeB, after sending the PDCCH command, is able to determine whether the UE successfully receives the PDCCH command, further improving the system performance.

Abstract: Embodiments of the present invention relate to the technical field of wireless communications, and specifically relate to a method, system and device for switching, for use in solving the problem in the prior art of the risk of communication interruption when a user equipment (UE) is switching due to greatly increased frequency and number of times of switching by the UE in an E-UTRAN network architecture. The method of the embodiments of the present invention comprises: a UE receives a DRB reconfiguration message from a macro base station; and the UE keeps a PDCP layer corresponding to all of the DRBs of a control side and of a user side at the macro base station, and switches other layers corresponding to some or all of the DRBs of the user side except the PDCP layer onto at least one base station. Because the embodiments of the present invention reduce the number of times of control side switching by the UE, in the case of increased frequency and number of times of switching by the UE in the E-UTRAN network architecture, the risk of communication interruption is reduced when the UE is switching.

Abstract translation: 本发明的实施例涉及无线通信的技术领域，具体涉及用于在用户设备（UE）中解决通信中断风险的现有技术中用于解决问题的用于切换的方法，系统和设备， 由于UE在E-UTRAN网络架构中的切换的频率和次数的大大增加而导致切换。 本发明实施例的方法包括：UE从宏基站接收DRB重配置消息; 并且UE在宏基站处保持对应于控制侧和用户侧的所有DRB的PDCP层，并且将与PDCP层以外的用户侧的一些或全部DRB对应的其他层切换到 至少一个基站。 由于本发明的实施例减少了UE的控制侧切换次数，所以在UE在E-UTRAN网络架构中的切换次数和次数增加的情况下，通信中断的风险降低 当UE正在切换时。
