  • Publication number: 20130308605
    Abstract: In a radio access network, novel systems and methods reduce processing delay, and improve integration with IP networks, by separating user data from connection management and control data at a Node B or at a base station. The user data are routed to an IP (Internet Protocol) switch, whereas the connection management and control data are routed to a centralized radio network controller (RNC). Pursuant to a second embodiment of the invention, a centralized RNC provides improved radio resource management (RRM) functionality by handing all connection management and control data for a plurality of Node B's, thereby simplifying the switching of user data throughout the radio access network. Pursuant to a third embodiment of the invention, a smart IP switch is equipped to switch user data without core network (CN) involvement. Downlink user data are switched independently of uplink user data.

  • Publication number: 20130301417
    Abstract: A system and method which permit the RNC to control purging of data buffered in the Node B. The RNC monitors for a triggering event, which initiates the purging process. The RNC then informs the Node B of the need to purge data by transmitting a purge command, which prompts the Node B to delete at least a portion of buffered data. The purge command can include instructions for the Node B to purge all data for a particular UE, data in one or several user priority transmission queues or in one or more logical channels in the Node B, depending upon the particular data purge triggering event realized in the RNC.

  • Patent number: 8565241
    Abstract: A medium access control (MAC) architecture reduces transmission latency for data block retransmissions. A plurality of data blocks are received and temporarily stored in a first memory (e.g., queue, buffer). The plurality of data blocks are then transmitted. A determination is made as to whether each of the transmitted data blocks was received successfully or needs to be retransmitted because the data block was not received successfully. Each of the transmitted data blocks that needs to be retransmitted is marked and temporarily stored in a second memory having a higher priority than the first memory. The marked data blocks are retransmitted before data blocks stored in the first memory location.

  • Publication number: 20130176970
    Abstract: A wireless digital communication system includes a base station in communication with a plurality of user equipment mobile terminals (UEs). The system prioritizes the forwarding of blocks of downlink data to designated ones of the UEs. The system employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provides optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink (DL) channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.
