摘要： Various processing options and systems are provided for setting/controlling feedback indicators referred to as “Happy Bits” in a wireless communication network using multiple uplink carriers. In one aspect, a Happy Bit is determined independently for each one of a plurality of uplink carriers based on channel conditions and buffer lengths for the respective carrier. For example, if a UE is transmitting the maximum data allowed by its serving grant for that carrier, the UE has available power to increase the data rate on that carrier, and the TEBS delay is greater than a certain threshold, then the Happy Bit for that carrier may be set to Unhappy to inform the Node B that the UE is capable of transmitting at a higher data rate on that carrier.

摘要： Techniques for estimating thermal noise and rise-over-thermal (RoT) in a communication system are described. In an aspect, thermal noise in a sideband may be measured and used to estimate thermal noise in a signal band. In one design, received power in the sideband may be measured, e.g., by computing total power of FFT transform coefficients within the sideband. Thermal noise may be estimated based on (e.g., by filtering) the measured received power in the sideband. Received power in the signal band may also be measured. Total received power may be estimated based on (e.g., by filtering) the measured received power in the signal band. RoT may then be estimated based on the estimated thermal noise and the estimated total received power. The estimated RoT may be used to estimate an available load for a cell, which may be used to admit and/or schedule users in the cell.

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： 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.
