摘要： Techniques for estimating thermal noise and rise-over-thermal (RoT) in a communication system are described. In an aspect, thermal noise in a sideband may be measured and used to estimate thermal noise in a signal band. In one design, received power in the sideband may be measured, e.g., by computing total power of FFT transform coefficients within the sideband. Thermal noise may be estimated based on (e.g., by filtering) the measured received power in the sideband. Received power in the signal band may also be measured. Total received power may be estimated based on (e.g., by filtering) the measured received power in the signal band. RoT may then be estimated based on the estimated thermal noise and the estimated total received power. The estimated RoT may be used to estimate an available load for a cell, which may be used to admit and/or schedule users in the cell.

摘要： Techniques for scheduling users for transmission on the uplink in a wireless communication system are described. In one design, a total load for a cell may be determined based on a rise-over-thermal (RoT) measurement. An in-cell load for users served by the cell may be determined based on uplink transmissions received from these users. An outside load due to users in neighbor cells may be determined based on the total load and the in-cell load. A target total load for the cell may be determined based on a target RoT for the cell. An available load for the cell may be determined based on the target total load for the cell and the outside load. Users in the cell may be scheduled for transmission on the uplink based on the available load for the cell.

摘要： A multimedia production method includes: reusing the content in the introduction before the main content or other part in the multimedia file for an outroduction after the main content and playing the audio and/or video content in the reverse direction. A producer can make the multimedia file by attaching such an outtrocution. A multimedia editing program can provide a user interface with menu options for such a production technique. The media production program could be associated with the multimedia sharing and distributing network. Such a production method could be applied to multiple multimedia files in the same media sharing and distributing network by the same producer. The same content can be reused in a cluster of media files.

摘要： A method and apparatus for wireless communication may provide an RLC reset procedure tailored for a multipoint HSDPA system utilizing a plurality of disparate Node Bs to provide an RLC flow from an RNC to a UE. Some aspects of the disclosure provide for a flush request to be provided to each of a plurality of Node Bs utilized as serving cells in the multipoint HSDPA system, so that stale packets are not retained in internal buffers at the Node Bs following the RLC reset procedure. In some examples, the RLC reset procedure is only completed after confirmation that the flush of the internal buffers has been completed. Confirmation may be explicitly provided by each Node B utilizing a backhaul interface, or may be implicitly determined utilizing timers or signaling between the respective Node Bs.

摘要： Techniques for scheduling users for transmission on the uplink in a wireless communication system are described. A cell may perform interference cancellation for uplink transmissions and may observe lower effective noise and interference due to interference cancellation. The lower effective noise and interference may allow the cell to operate with a higher effective target load, which may support a higher overall throughput for the cell. In one design, an effective target load for a cell using interference cancellation may be determined, e.g., based on a target rise-over-thermal (RoT) for the cell and an interference cancellation efficiency factor. An available load for the cell may be determined based on the effective target load, which may be higher than a target load for the cell without interference cancellation. Users in the cell may then be scheduled for transmission on the uplink based on the available load.
