    摘要: The present disclosure discloses a transmission power configuration method for a Demodulation Reference Signal (DMRS), and the method comprises: configuring the ratio between transmission power of a DMRS at each layer in a Resource Element (RE) and transmission power of data at a corresponding layer to be a constant value. Meanwhile, the present disclosure discloses a transmission power configuration apparatus for the DMRS. The present disclosure greatly improves the correct rate of data frame decoding, and improves decoding performance. The present disclosure enables the network side not need to notify a UE of the corresponding relationship between transmission power of DMRS at each layer and transmission power of data at the corresponding layer, which simplifies the overhead of the control signalling in the network side. As the corresponding relationship between transmission power of DMRS at each layer and transmission power of data at the corresponding layer is configured in the UE, the UE can implement channel estimation without waiting for the notification from the network side, which improves the channel estimation efficiency.

    摘要: Disclosed herein are methods and apparatus for network energy savings in a wireless communication system, such as the 3GPP LTE system. Particularly, one such method reduces power consumption in a base station by selectively muting or disabling downlink transmissions of certain control signal symbols in one or more subframes or frames. The disclosed methods and apparatus can apply independently or in combination in both FDD and TDD systems.

    摘要: Techniques, apparatuses, and systems for dynamically changing downlink and uplink allocations can include operating a base station under time division duplexing to communicate with one or more mobile devices using a frame structure, adjusting a downlink-uplink ratio to change an allocation between uplink and downlink data capacities in the frame structure, determining a mute interval based on the adjusted downlink-uplink ratio, generating mute information based on the mute interval to identify the one or more areas of the frame structure effected by the allocation change, and transmitting the mute information to the one or more mobile devices.

    摘要: A vertical turning-milling complex machining center comprises a horizontally-arranged bed body (6) and a vertically-arranged column (7). The bed body (6) is provided with an X-axis lateral supporting linear track (2) and an X-axis guide screw (5). The bed body (6) is also provided with a uniaxial rotating table (1) which can reciprocate and is driven directly by a first external rotor torque motor. The column (7) is vertically provided with a Z-axis lateral supporting linear track (10), a Z-axis guide screw (9) and a crossbeam (11) that reciprocates up and down. The crossbeam (11) is provided with a transverse Y-axis linear track (13), a Y-axis guide screw (12) and a single-pendulum milling head seat frame that can reciprocate along the Y-axis guide screw (12). The single-pendulum milling head is driven directly by a second external rotor torque motor. The vertical turning-milling complex machining center uses direct-drive technology applied to a B-axis and a C-axis, the motor torque is greatly increased and functional parts can stably operate, therefore the integral rigidity and stability of the machining center are improved.

    摘要: In the scheduling method of the present invention, scheduling grant messages for a user equipment are transmitted beginning in any time slot of a frame for a channel so long as the scheduling grant message does not exceed the frame. The scheduling grant message indicates user equipment is approved to transmit on an uplink dedicated channel. This downlink transmission and subsequent uplink dedicated channel transmission have a timing relationship such that no more than one user equipment will begin transmitting on a respective uplink dedicated channel at a time.
