Abstract: In aspects of the present disclosure, a user equipment receives inter-NodeB multi-point transmissions, and a multipoint aggregation component detects a gap in the sequence numbers, delays transmitting a not acknowledged signal (NAK) by starting a NAK delay timer, and transmits, by a transceiver, NAK for the gap in sequence numbers in response to the NAK delay timer expiring and detecting that the gap has not been filled during the delaying. If the Medium Access Control (MAC) entity as the respective NodeB identifies itself to the Radio Link Control (RLC), out-of-order delivery (skew) can eventually be distinguished from genuine data loss before the NAK delay timer expires based upon tracking the highest sequence numbers received. Adaptive NAK delay timer can be performed by monitoring skew duration.

Abstract: 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.

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

Abstract: A method and apparatus for wireless communication may provide for mobility in a Multi-Point HSDPA network capable of downlink aggregation. Some aspects of the disclosure provide modified mobility events utilized for altering the Active Set for a UE. Here, the addition of a cell to the Active Set can coincide with making that cell a secondary serving cell. Further, the deletion of a secondary serving cell from the Active Set can coincide with switching off the Multi-Point HSDPA mode. Still further, a modified mobility event for an HSDPA serving cell change can be utilized to swap a primary serving cell and a secondary serving cell.

Abstract: A base station (e.g., a Node B in a Multi-Point HSDPA network) calculates an amount of data to request from a network node (e.g., a radio network controller or RNC). As a part of the algorithm utilized, a length of a queue at the Node B for buffering the flow may be dynamically adjusted in an effort to optimize the trade-off between buffer underrun and skew. Further, a network node (e.g., the RNC) responds to Node B flow control requests. Here, the RNC may determine the amount of data to send to the Node B in response to the flow control message from the Node B, and may send the data to the Node B. In various aspects of the present disclosure involving a Multi-Point HSDPA system, the flow control algorithm at the RNC coordinates packet flow to the primary serving cell and the secondary serving cell for the UE.
