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： Techniques for managing operation of a user equipment (UE) in a multi-carrier system are described. The system may support two or more carriers on the downlink and one or more carriers on the uplink. One carrier on each link may be designated as an anchor carrier. In an aspect, a lower layer order (e.g., an HS-SCCH order) may be used to transition the UE between single-carrier and multi-carrier operation. In another aspect, the UE may have the same discontinuous reception (DRX) configuration for all downlink carriers and/or the same discontinuous transmission (DTX) configuration for all uplink carriers. In yet another aspect, HS-SCCH-less operation may be restricted to the anchor carrier.

摘要： Providing for fast allocation of additional carriers in multi-carrier wireless communication systems is described herein. By way of example, high layer protocols can be employed to allocate additional carriers to UEs in a wireless network. Additionally, management of the additional carriers can be accomplished via high speed lower layer signaling protocols. Management can involve activating/deactivating the additional carriers, instructing the UE to provide carrier feedback, monitor pilot or control channels of such carriers, or the like. Because lower layer signaling is relatively fast, activation or deactivation of the additional carrier can be quickly implemented in response to contemporaneous changes in channel conditions. Thus, changes to signal quality or network loading can be determined and utilized to customize carrier activation in near real-time, providing efficient resource allocation while conserving UE battery life.

摘要： Techniques for controlling transmission of packets on multiple links are described. In one design, a transmitter may generate packets of data for a receiver, assign the packets with sequence numbers from a single sequence number space, demultiplex the packets into multiple streams for multiple links, and send each stream of packets on the associated link to the receiver. The receiver may receive some packets in error, and the correctly received packets may be out of order. In one design, the receiver may maintain the largest sequence number of correctly received packets for each link. After detecting at least one missing packet, the receiver may send status information conveying the missing packet(s) and the largest sequence numbers for all links to the transmitter. The transmitter may use the largest sequence numbers for all links and its packet-to-link mapping to determine whether to quickly resend each missing packet or wait.

摘要： Techniques for performing admission control based on quality-of-service (QoS) performance in a wireless communication network are described. QoS performance (e.g., delay or throughput performance) of admitted data flows may be determined. Whether to admit or reject a new data flow may then be determined based on the QoS performance of the admitted data flows. The admitted and new data flows may have delay bounds. The QoS performance of the admitted data flows may be given by a measured sector delay, which may be determined based on actual delays of packets. A measured flow delay for each admitted data flow may be determined based on delays of packets for that flow. The measured sector delay may then be determined based on the measured flow delays for all admitted data flows. The new data flow may be admitted if the measured sector delay is less than a delay threshold.
