Abrégé

Teachings herein improve the choice of carrier placement in a wireless communication network by de-coupling the carrier raster from the subcarrier grid. Recognizing that the placement of a carrier by its center frequency is an artificial construct, it is re-defined and the carrier placement is instead defined by the carrier position, which is on a carrier raster (e.g., 100 kHz), but in general does not have to be the center of the carrier. Second, a subcarrier grid is defined that is common for all RF carriers and spanning a range of frequencies, at least within an operating band, and provides orthogonality for subcarriers within all RF carriers regardless of carrier position. Third, a unique mapping from the carrier position on the RF carrier raster to a subcarrier reference position, e.g., the DC subcarrier, is defined, which in turn identifies the exact position of the RF carrier on the subcarrier grid.

Abrégé

The embodiments reduce output delay for pictures by determining after a current picture has been decoded and stored in a decoded picture buffer, DPB, (125, 225, 325, 425, 525, 625), a number of pictures in the DPB (125, 225, 325, 425, 525, 625) that are marked as needed for output. This number is compared, after a current picture has been decoded and stored in the DPB (125, 225, 325, 425, 525, 625), against a value derived form at least one syntax element present or to be present in a bitstream (10) representing pictures of a video sequence. If this number is greater than the value a picture, which is the first picture in output order, of the pictures in the DPB (125, 225, 325, 425, 525, 625) that are marked as needed for output is preferably output and marked as not needed for output.

Abrégé

A network resource module communicatively interfaces a resource manager with one or more network nodes in a communications network. Each network node provides one or more network resources that may be used to create a virtual infrastructure for a virtual network. The network resource module detects the network nodes, abstracts the resources associated with the network nodes at a desired granularity (e.g., node level or flow level) into Virtual Resource Objects (VROs), and then publishes the VROs in a registry. Thereafter, Virtual Network Operators (VROs) select desired VROs from the registry to build the virtual infrastructure for the virtual network.

Abrégé

In a wireless network, plural downlink signals from plural base stations (210-1, 210-2, 210-3) are transmitted to a terminal (240). The plural downlink signals all carry the same information to the terminal (240). The terminal (240) provides feedback on the downlink channels. The feedback provides information on the taps of the channels. The amount of information fed back is constrained. Based on the feed-back, transmission parameters of the downlink signals are adjusted. The process of transmitting, providing feedback, and adjusting the parameters continue so that the energy of the downlink signal is enhanced at the terminal location and suppressed elsewhere. Beam forming can be used to further suppress the energy signature at locations other than the terminal location.

Abrégé

In one embodiment, a method of transmitting system information on a downlink shared channel structured as successive subframes includes transmitting (400 - 416) system information in regularly occurring time windows, each time window spanning some number of successive subframes. The method further includes indicating (406 / 408) to receiving user equipment (120) which subframes within a given time window carry system information. The method and variations of it are applied, for example, to the transmission of dynamic system information on the downlink shared channel or other downlink channel in a 3GPP E-UTRA wireless communication network (100).

Abrégé

A wireless communication network is configured to provide distributed diversity transmissions, wherein different diversity-coded versions of the same information signal are transmitted from each of two or more network sectors. The diversity-coded versions of the information signal are based on space-time or space-frequency codes, and the information signal may comprise a dedicated channel signal targeted to an individual user or a broadcast signal targeted to one or more users. Thus, spaced-apart network transmitters, which may be located at the same cell site, or at different cell sites, are configured to transmit diversity-coded versions of a given information signal and, in this manner, the advantages of space-time and/or space frequency transmission coding may be applied across multiple sectors of a communication network. Such transmissions may be used to improve soft and softer handoff reception of dedicated channel signals, and to improve reception of Broadcast- Multicast Services (BCMCS) signals, or the like.
