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.

摘要： 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.

摘要： 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.

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.

摘要： Data is scrambled at a transmitter according to one of a number of predetermined scrambling sequences which are associated with a particular one of a number of predetermined transmit antenna diversity schemes (i.e., a specific number of transmit antenna ports). Received data is decoded using one or more of the known transmit antenna diversity schemes and the scrambled data is descrambled according to a corresponding descrambling sequence (related to the scrambling sequence). Based on the descrambled data, the receiver determines which transmit antenna diversity scheme (i.e., the number of antenna ports) is used by the transmitter. In one specific embodiment, CRC parity data is scrambled in the transmitter and the receiver descrambles the recovered CRC parity data according to a descrambling sequence, computes CRC parity data from the received data, and compares the descrambled CRC parity data to the newly computed CRC parity data.
