Resource Allocation (epo) Patents (Class 375/E7.141)
  • Patent number: 11394518
    Abstract: System and method for flexible channel state information-reference signal transmission A method by a wireless device is provided for restricting channel state information (CSI) measurement. The method includes receiving, from a network node, information identifying a first subset of channel state information-reference signal (CSI-RS) resources to be used in performing CSI measurements. The first subset of CSI-RS resources are associated with a first portion of a frequency band that is less than all of the frequency band. CSI measurements are performed in the first subset of CSI-RS resources that are associated with the first portion of the frequency band.

  • Patent number: 8731056
    Abstract: It is an object of the present invention to provide an image encoding apparatus, an image encoding method, and an image encoding program, which can homogenize image quality of an image as a whole without lowering encoding efficiency, being operable at high speed, and reduce the size of circuit scale by performing macroblock shuffling without changing slice structure. Provided is an image encoding apparatus, including: a shuffling portion which collects and shuffles a plurality of macroblocks constituting image data from respective positions within an image; an encoding portion which performs space-frequency transform and entropy encoding on the plurality of macroblocks collected and shuffled by the shuffling portion, as a base unit; and a rate control portion which controls the encoding portion to adjust the rate of the plurality of macroblocks after the encoding.

  • Patent number: 8442569
    Abstract: In a case where a second reference signal for a second communication system is transmitted in addition to a first reference signal for a first communication system, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS, DVRB resources in which a resource unit defined in a frequency-time domain is divided in a time direction and distributedly allocated at predetermined frequency intervals are used and CSI-RS is allocated in a resource ID of a part of DVRB resources and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A.

  • Patent number: 8195180
    Abstract: A base station apparatus in a mobile communications system is provided. The base station apparatus includes a measuring unit which receives a reference signal from a user apparatus and measures received quality for each frequency resource block; a unit which provides a reference metric from the received quality; a modifying unit which modifies the reference metric with at least first and second parameters, and provide the modified metric; a scheduler which compares modified metrics of respective frequency resource blocks and provides a radio resource allocation plan; and a unit which reports, to the user apparatus, control information which indicates the allocation plan.

  • Patent number: 8134558
    Abstract: Systems and methods for editing of a computer-generated animation across a plurality of keyframe pairs are provided. Embodiments enable time editing across a plurality of non-roving keyframe pairs. Such non-roving keyframes have fixed references relative to an animation's reference timeline. An author may specify a point on an animation's reference timeline at which each non-roving keyframe is placed. In accordance with embodiments of the present invention, an animation across a plurality of non-roving keyframes is treated as an editable unit. Thus, an author may modify the timing for all or a select portion of such editable unit (which may span a plurality of the non-roving keyframes). For instance, an author may expand or reduce the time span for a plurality of non-roving keyframes, and the timing of the plurality of non-roving keyframes automatically adjusts to maintain their timing proportionality relative to each other in the resulting modified time span.

  • Patent number: 8085875
    Abstract: Dynamic resource allocation systems, apparatus, and methods are disclosed for selectively improving the ability of a receiver to determine a channel estimate in an Orthogonal Frequency Division Multiple Access (OFDMA) system. A wireless communication system can use a common pilot channel configuration to aid channel estimation in one or more receivers in communication with the system. A receiver in communication with the system may be unable to demodulate received data due to an inaccurate channel estimate. The receiver can communicate to a transmitter in the system a request for additional channel estimation resources. The wireless communication system can provide additional channel estimation resources by inserting dedicated pilot channels into one or more of the frequencies allocated to symbols for the receiver. If the receiver is still unable to demodulate received data, the wireless communication system can incrementally insert additional pilot channels in the symbol associated with the receiver.
