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.
The embodiments of the present invention relates to a method in a UE for distributing available transmit power to avoid violation of UE power limitations on the PUCCH and the PUSCH. Available power for transmission on at least the PUCCH is determined and at least one power headroom report indicating the available power for transmission on at least the PUCCH is transmitted to a base station.
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.
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).
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.
