Abstract: Providing 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.

Abstract: Systems, methods, devices, and computer program products are described for transmission of downlink channel quality information and acknowledgment information in a multi-carrier wireless communication system. Channel quality information may be estimated for a number of downlink carriers. An uplink control channel may be configured in a flexible manner based on the number of activated carriers and whether those carriers are configured with MIMO. The feedback cycle for the channel quality information may remain constant.

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 adjusting at least one of an open loop control, an inner loop control, or an outer loop control in view of the power levels for the set of packet access signals.

Abstract: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In particular, an enhanced pilot reference may be provided for enabling increased data rates on a secondary stream. Specifically, a primary stream, provided on a primary virtual antenna (610), includes an enhanced primary data channel E-DPDCH (624), a primary control channel DPCCH (622), and an enhanced primary control channel E-DPCCH (614). Further, a secondary stream, provided on a secondary virtual antenna (612), includes an enhanced secondary data channel S-E-DPDCH (620) and a secondary control channel S-DPCCH (618). Here, the secondary control channel S-DPCCH (618) may be transmitted at a boosted power level relative to a determined reference power level.

Abstract: A base station can employ a shared resource, such as a control channel, for communication with a mobile device. The mobile device can be granted the exclusive access to the shared resource for a limited time. The exclusive access can be such that there is not a limit in message size that can be transferred across the shared resource. To improve operation, the exclusive grant can be applied until it is determined that appropriate packets are transferred.

Abstract: Techniques for supporting operation with enhanced uplink in inactive state are described. A user equipment (UE) may send an access preamble for random access while in an inactive state and may receive a message containing resources allocated to the UE. The allocated resources may be selected by a Node B from a pool of resources pre-allocated to the Node B for the enhanced uplink. The UE may send information (e.g., scheduling information and/or its UE identity) to the Node B using the allocated resources. The UE may receive an acknowledgement addressed to the UE based on the UE identity. The UE may remain in the inactive state and continue to use the allocated resources until they are de-allocated. Alternatively, the UE may transition to an active state and either continue to use the allocated resources or receive an allocation of new resources for the active state.

Abstract: A method and apparatus provide hybrid automatic repeat request (HARQ) feedback corresponding to the status of multiple downlink carriers, with or without MIMO being configured. Here, for at least some configurations, with respect to the selection of HARQ feedback symbols, the downlink carriers are grouped into groups of one or two carriers such that HARQ feedback symbol code books that were previously implemented in conventional HSDPA or DC-HSDPA systems may be utilized. That is, after encoding a data stream, HARQ feedback symbols selected from a plurality of code books configured for groups of one or two of the downlink carriers are utilized to modulate an uplink channel. The modulation or channelization may be accomplished with dual channelization codes or a single channelization code with a reduced spreading factor to insert two symbols into a single time slot.
