Abstract: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In one aspect, a UE determines a number of acknowledgement/negative acknowledgement (ACK/NACK) bits for a data transmission on one more component carriers (CCs) based on information obtained from a grant. The grant may be a downlink grant or an uplink grant, and the information obtained may include a number of CCs scheduled for data transmission and/or identifiers of the scheduled CCs. The UE may determine the number of ACK/NACK bits for acknowledging the data transmission based on the number of scheduled CCs and the identifier of each scheduled CC.

Abstract: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.

Abstract: Systems and methods for facilitating inter-cell interference coordination using load indication are described. A UE may receive load indicator signals from a plurality of base stations in adjacent cells and determine, based at least in part on the load indicator signals, a transmit power metric. The transmit power metric may be provided to a serving base station, which may allocate uplink resources based on the transmit power metric. Additional information related to receiver sensitivity and/or path loss may be used to determine the transmit power metric.

Abstract: Systems and methodologies are described that facilitate system frame number (SFN) indication and identification during a random access procedure (e.g., associated with a handover). As described herein, a target cell can configure one or more Random Access Responses (RARs) designated for transmission to a terminal during the access phase of a handover to include the SFN of the target cell. Techniques are further described herein by which the target cell can include SFN information in a sub-header associated with a RAR, in the payload of a RAR, and/or in other appropriate manners. In addition, the target cell can configure one or more flags of the RAR to indicate the presence of SFN information. Upon receiving a RAR with embedded SFN information, a terminal can utilize the SFN for operations such as frequency hopping or uplink resource configuration as described herein.

Abstract: Channel dependent credit accumulation for determining a mobile handover is provided herein. In some aspects, a characteristic(s) of a source channel(s) serving a mobile device and of one or more target channels can be evaluated. Magnitudes of the evaluated characteristics can be utilized to generate handover credits associated with the target channel(s) (e.g., based on some function of a difference in the magnitudes). If a concurrent number of credits associated with a target channel equals or rises above one or more threshold levels, a mobile device can initiate a handover. As described, disparity in source and target channel quality, signal strength, etc., can be determined to increase probability of a handover based on channel degradation over one or more time intervals.

Abstract: Systems and methodologies are described that facilitate handing over mobile device communications in a wireless network from a source base station to a target base station without using a random access channel (RACH). In this regard, the mobile device can monitor multiple base stations determining timing information related thereto and access scheduling request channels for the base stations. When ready for handover, the mobile device can request data resources over the scheduling request channel using the appropriate timing information.

Abstract: A data traffic responsive battery-saving approach for a wireless user equipment (UE) device such as an data packet capable cellphone incorporates flexible discontinuous transmission and reception (DTX-DRX) when in Long Term Evolution (LTE) active mode as dictated by an evolved radio access network (RAN) such as an evolved base node (eNode B). A UE device requests are made on unsynchronized random access channel (RACH). Lengthening a duration of DRX and reducing requirements for synchronization uplink transmissions results in power savings of up to 75%, as well as creating opportunities for reducing interference and for allocating additional time slots for data. This power savings is compatible with other downlink scheduling proposals, with control channel-less Voice-over-IP (VoIP), and need not target those UE devices in bad radio conditions. Legacy UE devices that can interact with the eNode B by being capable of radio resource control (RRC) signaling continue to be compatible.

Abstract: Techniques for deriving channel estimates with different channel estimation filters are described. In one scheme, a filter selection metric is determined for a signal to be recovered, a channel estimation filter is selected based on the filter selection metric, and a channel estimate is derived with the selected channel estimation filter. In another scheme, a first channel estimate is derived with a first channel estimation filter having a first filter response, a first signal is recovered with the first channel estimate, and interference due to the first signal is estimated and removed. A second channel estimate is derived with a second channel estimation filter having a second filter response that is different from the first filter response.
