Abstract: 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.

Abstract: Methods and apparatuses for facilitating managing cells in a multi-carrier system from an access terminal and base station are provided. The base station and access terminal communicate via an anchor carrier and a supplementary carrier. A triggering algorithm generated by the base station is transmitted to the access terminal. The triggering algorithm includes instructions for the access terminal to report downlink measurements as a function of trigger events detected over the anchor carrier and/or the supplementary carrier. Downlink measurements taken by the access terminal are provided to the base station. Cell management instructions based in part on the downlink measurements are then provided to the access terminal by the base station.

Abstract: FAST CARRIER ALLOCATION IN MULTI-CARRIER SYSTEMSProviding for fast allocation of additional carriers (402) 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 (304) in a wireless network. Additionally, management of the additional carriers can be accomplished via high, speed lower layer signaling protocols (206B). 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.Figure 3

Abstract: A method for wireless communications is provided. The method includes applying independent power controls to two or more carriers from a set of high speed packet access signals. The method includes monitoring power across the two or more carriers to determine power levels for the set of high speed packet access signals. The method also includes automatically scaling at least one of the independent power controls in view of the determined power levels for the set of high speed packet access signals. The method also includes setting the minimum power offset of the data channel independently on each carrier.

Abstract: 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 os 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.

Abstract: Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.

Abstract: An apparatus and method for participating in wireless communications. The method comprises employing (902) a wireless communication interface to obtain a multi-carrier assignment from a wireless network component, employing (904) the communication interface to obtain a physical layer or layer two signaling protocol message, employing (906) a data processor to extract a command pertaining to a non-anchor carrier of the multi-carrier assignment from the message, and activating or deactivating the non-anchor carrier based on the command. Deactivating the non-anchor carrier further comprises at least one of ignoring signaling on the non-anchor carrier, terminating processing on the non-anchor carrier, or ignoring non-pilot or non-shared control channel signaling on the non-anchor carrier.
