摘要： The present disclosure provides methods and apparatuses for improved Iub link congestion management based on a dynamic scaling of flow control request message transmission in multiflow wireless environments. For example, in an aspect, methods and apparatuses are provided for receiving, at a NodeB, a data request from one or more user equipment (UE), wherein each data request corresponds to a flow and the one or more UE is served by a plurality of NodeBs, generating a flow control request corresponding to each flow in response to each data request, and sending each flow control request to a radio network controller (RNC). Thereafter, a Node B may receive data in response to each flow control request, determine a congestion state based on a downlink delay from the RNC detected in the received data, and scale a subsequent one or more flow control requests based on the determined congestion state.

摘要： A method and apparatus for wireless communication may provide a multi-link RLC sublayer in an RNC capable of allocating RLC PDUs among a plurality of MAC entities for use in a Multi-Point HSDPA network. Some aspects of the disclosure address issues relating to out-of-order delivery of the RLC PDUs to a UE, such as unnecessary retransmissions. That is, the disclosed multi-link RLC may be capable of distinguishing between sequence number gaps that are caused by physical layer transmission failures and those caused merely by skew.

摘要： Techniques for scheduling users for transmission on the uplink in a wireless communication system are described. A cell may perform interference cancellation for uplink transmissions and may observe lower effective noise and interference due to interference cancellation. The lower effective noise and interference may allow the cell to operate with a higher effective target load, which may support a higher overall throughput for the cell. In one design, an effective target load for a cell using interference cancellation may be determined, e.g., based on a target rise-over-thermal (RoT) for the cell and an interference cancellation efficiency factor. An available load for the cell may be determined based on the effective target load, which may be higher than a target load for the cell without interference cancellation. Users in the cell may then be scheduled for transmission on the uplink based on the available load.

摘要： Techniques for scheduling users for transmission on the uplink in a wireless communication system are described. In one design, a total load for a cell may be determined based on a rise-over-thermal (RoT) measurement. An in-cell load for users served by the cell may be determined based on uplink transmissions received from these users. An outside load due to users in neighbor cells may be determined based on the total load and the in-cell load. A target total load for the cell may be determined based on a target RoT for the cell. An available load for the cell may be determined based on the target total load for the cell and the outside load. Users in the cell may be scheduled for transmission on the uplink based on the available load for the cell.

摘要： A Multi-Point HSDPA system may provide downlink aggregation from multiple cells for a single receive antenna UE without requiring an advanced Type 3i receiver, by providing switching-based scheduling from one of the cells based on channel conditions of the respective cells, as reported by the UE. For example, the UE may monitor the HS-SCCH from both cells so that it may decode the HS-DSCH in any particular TTI as data is scheduled. The UE may further transmit a CQI for each of the cells, so that scheduling decisions between the cells at each TTI may be dynamically made to provide the downlink packet from the better of the cells.
