    Abstract: Methods and apparatuses are provided in which a user equipment (UE) receives a system information block (SIB) from a network. The UE identifies at least one downlink (DL) period based on a first uplink (UL)/DL configuration included in the SIB. The UE monitors a physical downlink control channel (PDCCH) during the at least one DL period using a discontinuous reception (DRX) operation. The UE obtains downlink control information (DCI) for indicating at least one second UL/DL configuration as a format for one or more time intervals from the monitored PDCCH. The UE determines the format for the one or more time intervals based on the obtained DCI. The monitoring of the PDCCH includes monitoring the PDCCH in an active time of a DRX cycle. The active time includes a time when the UE performs continuous reception.

    Abstract: Methods and apparatuses are provided for monitoring a physical downlink control channel (PDCCH) in a wireless communication system. A UE receives a system information block (SIB) from a base station. The UE obtains a first time division duplex (TDD) uplink (UL)/downlink (DL) configuration from the SIB. The UE identifies DL subframes in a radio frame. The UE monitors the PDCCH transmitted from the base station on a DL subframe included in an on duration period of a discontinuous reception (DRX) cycle. The UE obtains information about a second TDD UL/DL configuration from the monitored PDCCH. The UE applies the second TDD UL/DL configuration to the radio frame. The DL subframe corresponds to a predetermined subframe number in the radio frame. The on duration period represents a period corresponding to a predetermined number of subframes from a subframe where the DRX cycle starts, and the on duration period is repeated periodically.

    Abstract: A method and an apparatus for activating and deactivating secondary cells in a carrier aggregation environment are provided. In one embodiment, a Medium Access Control (MAC) Control Element (CE) command is received from a base station for activating/deactivating a secondary cell associated with a User Equipment (UE). The secondary cell configured for the UE is activated/deactivated based on the MAC CE command. Further, a first uplink grant is received from the base station upon activation/deactivation of the secondary cell. Accordingly, quality information (e.g., channel quality information, sounding reference signal information, and the like) associated with the cell(s) is transmitted to the base station in the received first uplink grant over a physical uplink shared channel. Furthermore, a hybrid automatic repeat request entity associated with the secondary cell is reset.

    Abstract: The present invention relates to a method of configuring a set of Radio Access Network (RAN) parameters including Discontinuous Reception (DRX) configurations for user equipment in a wireless networking system. The method includes determining traffic characteristics associated with user equipment based on the number and types of applications running in it. The method further incudes steps of modifying and updating the DRX configurations and the RAN parameters for different situations of wireless transmission and reception. The updated DRX configurations and the RAN parameters for communication with the user equipment results in an efficient power consumption management.

    Abstract translation: 本发明涉及一种配置无线接入网络（RAN）参数的方法，所述无线接入网络（RAN）参数包括无线网络系统中的用户设备的不连续接收（DRX）配置。 该方法包括基于在其中运行的应用的数量和类型确定与用户设备相关联的流量特性。 该方法还包括针对不同的无线发送和接收情况修改和更新DRX配置和RAN参数的步骤。 用于与用户设备通信的更新的DRX配置和RAN参数导致有效的功率消耗管理。
