Abstract: Embodiments of the present invention disclose a method and an apparatus for determining an active time of UE, where the method includes: acquiring extension information of a DTX active time of a base station, where the extension information is used to indicate extension performed by the base station on the DTX active time of the base station; and adjusting a DTX active time of the UE according to the extension information, and using an overlapped time between the DTX active time of the UE and a DRX active time of the UE as an active time of the UE for listening on a PDCCH channel, where the DTX active time of the UE is the DTX active time of the base station learned by the UE. When a base station changes original DTX of the base station for the sake of QoS of UE or the like, in the present invention, the UE can learn a latest DTX condition according to a change of the DTX on a base station side in a manner of acquiring extension information of a DTX active time of the base station, and therefore can determine a correct active time of the UE with reference to DRX of the UE, thereby ultimately ensuring QoS of the UE.

Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (eg. 10 GHz˜100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The wireless system deployed in mmWave/cmWave system is expected to employ DL beam sweeping on broadcast control information to provide cell coverage to the UE which would result in excessive signaling overhead.

Abstract: This invention concerns concepts for signaling resource allocation information to a terminal that indicates to the terminal assigned resources for the terminal. The terminal can receives downlink control information (DCI), which comprises a field for indicating the resource allocation information of the terminal. This resource assignment field within the DCI has a predetermined number of bits. The terminal can determines its assigned resource allocation information from the content of the received DCI, even though the bit size of the resource allocation field in the received DCI is insufficient to represent all allowed resource allocations. According to an embodiment, the received bits that are signaled to the terminal in the DCI represent predetermined bits of the resource allocation information. All remaining one or more bits of the resource allocation information that are not included in the field of the received DCI are set to predetermined value.

Abstract: Methods, systems, and devices are described for hierarchical modulation and interference cancellation in wireless communications systems. Various deployment scenarios may be supported that may provide communications on both a base modulation layer as well as in an enhancement modulation layer that is modulated on the base modulation layer, thus providing concurrent data streams that may be provided to the same or different user equipments. Various interference mitigation techniques may be implemented in examples to compensate for interfering signals received from within a cell, compensate for interfering signals received from other cell(s), and/or compensate for interfering signals received from other radios that may operate in adjacent wireless communications network.
