摘要:
There is disclosed a system for transmitting data to users. The system includes nodes interconnected by at least one data network. The nodes are organized hierarchically to comprise a root node and at least two child nodes. The data transmission characteristics of communication with each of the child nodes are different. The root node is configured to: receive data transmission preferences of a particular user; receive data to be transmitted to the particular user; and transmit a selected subset of the data to at least one of the child nodes. The subset selected based on at least the received data transmission preferences and the data transmission characteristics, to permit the particular user to obtain data from the child nodes according to the data transmission preferences. The at least one of the child nodes being configured to: receive data from the root node; and transmit at least part of the received data to the user.

Methods, devices and systems are provided for incorporating a consideration of the quality of service (QoS) of different end-to-end paths in a network, or portions thereof, into the scheduling of uplink data and the selection of data by a user device for transmission to one or more target reception points in a network. The target reception points may be determined from a number of possible reception points by a scheduling entity or by a network access node, gateway or other entity in the network and provided to a user device along with one or more indications of QoS for an uplink scheduling grant.

A hierarchical link scheduling system and method is provided. A central controller gathers network information, including global parameters and long term demands, and determines an initial schedule for link activation based on these variables. A scheduler receives the initial schedule and modifies the initial schedule based on local parameters, inter-schedule negotiation, or other short term or localized requests. The scheduler activates the links according to the modified schedule. Accordingly, the scheduler can be responsible for modifying the initial schedule provided by central controller with localized or short term requests or demands, and providing the necessary parameters to enable link activation between nodes according to the modified schedule.

摘要:
Systems, apparatus and methods for validating whether an interfering communications signal has been encountered by a node in a wireless communications network due to signals transmitted by a node operating in another wireless communications network. The wireless communications networks may operate as directional wireless communications networks. Signals transmitted by a node may include an indicator which is associated with a particular node or wireless link. The indicator or information used to generate the indicator may be provided to a third party such as a network operator or regulator. If a received signal includes an interfering signal transmitted by another node, a report of the interfering signal is validated by sending the indicator included in the signal to the third party to check against indicators of transmitting nodes.

A method and apparatus are provided for handling uplink data traversing a backhaul in a Radio Access Network (RAN). Uplink data received at access nodes of the RAN is processed by processing functions separate from the access nodes. The processing functions provide processed data for use, by further nodes, in decoding of the information transmitted from client devices. Processing can include one or more of: regenerating uplink signals, requantizing signals, and selecting a portion of received data to forward. A scheduler which controls various access nodes and processing functions concurrently with issuance of uplink grants is also provided.

Embodiments of the present disclosure are directed towards a communications system and uplink transmission method which may dynamically adapt to changing conditions of the backhaul network. A traffic engineering element (TEE) is disclosed which receives a request from at least one wireless device for uplink data transmission. The TEE then determines the backhaul conditions of the backhaul network and coordinates uplink data transmissions from at least one wireless device to one or more receivers dependent on the determined backhaul conditions.

A method and apparatus for balancing multipoint Radio Access Network traffic to mitigate backhaul congestion is provided. Schedulers communicate with a Traffic Engineering (TE) controller either directly or via a Virtual Link Monitor. The schedulers receive indications of data rate upper limits for virtual links overlaid onto the backhaul network, and schedule mobile device communications such that the data rate upper limits are respected. The Virtual Link Monitors maintain indications of current loading of the virtual links and provide the schedulers with operational information based on same. Scheduling is performed in view of the operational information. The Virtual Link Monitors also provide the TE controller with indications of service requirements for the virtual links, so that the TE controller can reconfigure the virtual links based on same.

A method and apparatus for facilitating communication through a wireless communication system configured for transmission of general-purpose data, are provided. A transparent radio bearer is instantiated in a device and is configured to interface with an application of the device. A transparent logical channel is also instantiated in the device and is configured to interface with a medium access layer of the device. The medium access layer forms a part of a chain of protocol layers operatively configured to facilitate communications to another device associated with the wireless communication system. The transparent radio bearer maps onto the transparent logical channel in order to bypass at least one sub-layer of the chain of protocol layers while conveying data between the application and the medium access layer of the device.
