摘要： Systems and methodologies are described that facilitate indicating channel resource usage information for receiving additional channel resources in a wireless network. An access point can initially receive a set of channel resources from a network controller for providing wireless network access to one or more devices. The access point can grant and/or deny requests for one or more of the channel resources from a plurality of devices and can feedback information to the network controller regarding the granting/denying. The network controller can determine a load on the access point based at least in part on the feedback information and adjust channel resource allocation based on the load. Thus, where an access point has granted close to capacity of allocated resources to one or more devices, the network controller can provide additional resources to the access point based on received feedback information related to the granted resources.

摘要： A system and method enable wireless user equipment (UE) to undergo a serving radio network subsystem (SRNS) relocation to a radio network controller (RNC) that does not support a fast dormancy feature while maintaining synchronization with the packet-switched domain of the core network. The UE is made aware of whether the target RNC supports the fast dormancy feature by way of an indication provided to the UE in a reconfiguration message provided by the source RNC, that is, the RNC to which the UE was connected prior to the SRNS relocation. In this way, the UE can behave accordingly whether or not the target RNC supports the fast dormancy feature.

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.
