Abstract: The present invention provides a method and an apparatus for transmitting an uplink signal, where the method includes: receiving information that is of a network resource and sent by a scheduling cell, where the scheduling cell is a neighboring cell of a serving cell to which the user equipment belongs; and sending the information of the network resource to the user equipment, so that the user equipment sends the uplink signal by using the network resource. In the method and apparatus for transmitting an uplink signal according to embodiments, the uplink signal is sent by allocating the user equipment with the network resource of the scheduling cell with a small power loss, thereby ensuring quality of the uplink signal as far as possible.

Abstract: Embodiments of this application disclose a multi-user pairing method and apparatus, and a base station. The method includes: obtaining an actual downlink channel parameter of user equipment UE at a moment t0; calculating a correlation coefficient between the actual downlink channel parameter at the moment t0 and an actual downlink channel parameter of the UE at a moment t0−Δt; determining a predicted downlink channel parameter of the UE at a moment t1 if the correlation coefficient is less than a preset threshold; and performing a multi-user pairing operation based on the predicted downlink channel parameter at the moment t1.

Abstract: Embodiments provide a resource allocation method, apparatus, and system. The apparatus includes a channel proxy unit and multiple user equipment (UE) proxy units. The multiple user equipment (UE) proxy units are configured to determine separately, for multiple UEs, a resource set to be applied for, and separately apply to the channel proxy unit for grant of the determined resource set to be applied for. The channel proxy unit is configured to coordinate grant applications of the multiple UE proxy units, and transmit granted-resource information to each UE proxy unit according to a coordination result, where the granted-resource information indicates granted resources, of a UE proxy unit receiving the granted-resource information, in a resource set that is to be applied for and that is determined by the UE proxy unit.

Abstract: The application relates to a method and a transmitter communication device configured to provide video data to a receiver communication device, wherein the video data comprises one or more groups of frames and each group of frames comprises a plurality of temporally successive frames. The method comprises processing a first frame of a current, i.e. currently processed group of frames using a first modulation and coding scheme of a plurality of modulation and coding schemes and processing a second frame of the current group of frames using a second modulation and coding scheme of the plurality of modulation and coding schemes, and further selecting the second modulation and coding scheme of the plurality of modulation and coding schemes on the basis of a temporal position of the second frame relative to the first frame of the current group of frames.

Abstract: Traffic profiling in real time within a video streaming session is described. Multiple data packet flows at a lower layer of the OSI model are observed. A data packet flow pattern is obtained for each observed flow, and each obtained pattern is compared to a pre-defined characteristic streaming pattern. From the observed flows, any data packet flow that has its data packet flow pattern close to the pre-defined characteristic streaming pattern is selected as a video streaming flow. A buffer state of the video streaming flow is identified amongst a filling state, a steady state, and a depletion state, by observing a slope of accumulated data over time. Eventually, multimedia-related information of the selected video streaming flow is provided based on its data packet flow pattern.
