    摘要: Various examples of the present disclosure describe a random access method and device in a CR system. The method includes: generating, by a base station device, a spectrum handover command, wherein the spectrum handover command comprises random access backoff time parameter information; and sending, by the base station device, the spectrum handover command to a user equipment in a cell to instruct the UE to initiate, during a spectrum handover procedure, a random access procedure using the random access backoff time parameter information. According to the various examples of the present disclosure, the random access backoff time parameter information is carried in the spectrum handover command, so that a random access conflict is suppressed during the spectrum handover procedure of the CR system. A large number of UEs that intensively perform random access on a target working frequency are pre-dispersed in time. As such, the delay and the failure probability of the random access on the target working frequency during the spectrum handover procedure are reduced, and thus the failure probability of the spectrum handover and the service interruption time are reduced, so that the user experience of the CR system is improved.

    摘要: A method for achieving energy-saving in a mobile communication system base station, for application in an LTE system, comprising: determining the average value of a downlink sub-frame traffic load; determining, when the average value of the downlink sub-frame traffic load is below a threshold value therefore, an MBSFN downlink sub-frame which is not carrying multicast traffic; and closing the radio frequency channel corresponding to the multicast symbol in the MBSFN downlink sub-frame which is not carrying multicast traffic. By using the method, the number of downlink sub-frames required to meet the communication traffic needs of a current cell is judged according to changes in the traffic load observed by measuring the traffic load values in that cell; sub-frames which can be closed are set as MBSFN downlink sub-frames which do not send multicast traffic; radio frequency channels occupied by the multicast symbol are closed, thereby reducing energy consumption.

    摘要: The present invention discloses a method for configuring a Physical Downlink Control Channel (PDCCH), a base station and a UE, wherein the base station configures a component carrier or component carriers for monitoring the PDCCH for the UE and notifies the UE about information on the configured component carrier or component carriers so that the UE monitors the PDCCH only over the configured component carrier or component carriers. Stated otherwise, in this way, the UE will operate only over a necessary component carrier or component carriers without monitoring respective component carriers in an LTE-A system to thereby reduce the number of concurrently monitored component carriers, and in the case of nonconsecutive component carriers, also reduce the number of consequently enabled receivers and consequently the amount of consumed power of the UE for monitoring the PDCCH.
