TL;DR: In this article, a method for increasing the feedback capacity of an uplink of a time division duplex system was proposed, which can reduce the delay of power control, channel information feedback and dynamic dispatching on the uplink.
Abstract: The invention relates to a method for increasing feedback capacity of an uplink of a time division duplex system, which includes the following steps: step 1 within an uplink time slot of a wireless frame on a bidirectional spectrum in the time division duplex system and on the bidirectional spectrum, a terminal sends signals to a base station; step 2 within a time slot of a wireless frame on a downlink unidirectional spectrum which is corresponding to the uplink time slot in the time division duplex system and on the downlink unidirectional spectrum, the terminal receives feedback information sent by the base station. The invention can allow the feedback delay of the time division duplex system to be smaller than a period of a wireless frame, thus shortening the delay of power control, channel information feedback and dynamic dispatching on the uplink in the time division duplex system and greatly increasing the throughout capacity of the uplink in the time division duplex system as well as the support capacity for a high-speed mobile terminal. By adopting the invention, the time division duplex system keeps the inherent advantages and further has the advantages of small delay for closed loop control in an FDD system and support of high-speed movement.

15 Jul 2008TL;DR: In this article, the dummy pattern disposition area is arranged away from at least one of boundaries between a corresponding division area of the plurality of division areas and adjacent division areas, so that the dummy patterns are placed away from the boundaries of the corresponding division areas.
Abstract: A method of designing a semiconductor integrated circuit, includes dividing a layout area in which a wiring pattern is disposed, into a plurality of division areas, determining a dummy pattern disposition area provided in each of the plurality of division areas, adding a dummy pattern to the dummy pattern disposition area of each of the plurality of division areas, and combining division areas to which the dummy pattern is added. The dummy pattern disposition area is arranged away from at least one of boundaries between a corresponding division area of the plurality of division areas and adjacent division areas.

15 Sep 2000TL;DR: In this article, a signal transport system and a transport method for a client overhead received from a client network is provided. But the overhead is transferred in the wavelength division mode represented by one wavelength to the receiver.
Abstract: A signal transport system and a transport method are provided A whole lowspeed signal containing a client overhead received from a client network is transparently subjected to time division multiplexing and an additional overhead is inserted in the whole signal and further subjected to wavelength division multiplexing, so that the digital signal having the addition overhead is transported in the wavelength division mode represented by one wavelength to a receiving equipment
