Abstract: Embodiments disclosed herein address the need in the art for an extended acknowledgment/rate control channel. In one aspect, an acknowledgment command and a rate control command are combined to form a combined command. In another aspect, the combined command is generated in accordance with a constellation of points, each point corresponding to a pair consisting of a rate control command and an acknowledgment command. In yet another aspect, the points of the constellation are designed to provide the desired probability of error for the respective command pairs. In yet another aspect, a common rate control command is transmitted along with a combined or dedicated rate control command. Various other aspects are also presented. These aspects have the benefit of reduced overhead while providing acknowledgment and rate control to single remote stations and/or groups of remote stations.

Abstract: The invention includes a device and method for improving the responsiveness of the transmitter power control function so that the transmission power is more quickly and accurately controlled over a wider range of dynamic power adjustment during transmission. The present invention is directed to a dynamic transmission power control device and methodology having improved power control loop bandwidth and low power control loop variance. The invention is particularly useful for wireless communications, and more particularly to wireless digital devices having signals with large information frame size and low target frame error rate (FER). The dynamic transmission power control methodology includes a receiver including multiple power control loops for dynamically determining the amount of adjustment to make to the incoming transmission signal to achieve a desired level of signal quality at the lowest possible transmission power. For example, two power control adjustment loops, for example an outer loop and an outer-outer loop, may be provided for determining a target signal to noise ratio (SNR). The receiver may also include an inner loop. In one preferred embodiment, the transmitter may use turbo coding decoded using an iterative decoder for forward error correction. In one variation, the turbo coding is used on the forward supplemental channel (F-SCH).

Abstract: Downlink schemes are disclosed for a cooperative user equipment (UE) with joint baseband processing. UEs may establish a cooperative UE unit with one or more neighboring UEs, where one of the UEs operates as the primary UE. The participating UEs of the cooperative UE unit determine a downlink transmission scheme for the cooperative transmissions from a serving base station and receive cooperative transmissions of one or more transport blocks from the serving base station according to the downlink transmission scheme. The secondary UEs of the cooperative UE unit generate and transmit cooperative process data to the primary UE, where the cooperative process data is based on the receipt of the cooperative transmissions by the secondary UEs. The primary UE processes its received cooperative transmission along with the cooperative process data to decode the one or more transport blocks. Other aspects and features are also claimed and described.

Abstract: Techniques for supporting peer-to-peer (P2P) communication in a wide area network (WAN) are disclosed. In an aspect, interference coordination between P2P devices engaged in P2P communication and WAN devices engaged in WAN communication may be performed based on a network-controlled architecture. For the network-controlled architecture, P2P devices may detect other P2P devices and/or WAN devices and may send measurements (e.g., for pathloss, interference, etc.) for the detected devices to the WAN (e.g., serving base stations). The WAN may perform resource partitioning and/or association for the P2P devices based on the measurements. Association may include selection of P2P communication or WAN communication for a given P2P device. Resource partitioning may include allocation of resources to a group of P2P devices for P2P communication. The WAN may send the results of association and/or resource partitioning to the P2P devices, which may communicate in accordance with the association and/or resource partitioning results.

Abstract: Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to systems and methods for managing inter-cell interference coordination (ICIC) actions for time-domain partitioned cells. In certain aspects, time-domain partitioning is accounted for by an ebb in determining whether to send frequency-based inter-cell interference information (e.g., uplink overload indicator) to neighboring ebb(s) and/or responsive actions to take in response to receiving frequency-based inter-cell interference information (e.g., uplink overload indicator, high interference indicator, and/or relative narrowband transmission power).

Abstract: Techniques for supporting fallback operation in a multi-carrier communication system are described. In one aspect, a UE may determine at least one first downlink control information (DCI) format to monitor on a first carrier.

The UE may receive a reconfiguration message related to communication on a plurality of carriers by the UE with cross-carrier signaling, and may determine at least one second DCI format to monitor on the first carrier based on the reconfiguration message. The UE may monitor for the first DCI format(s) and the second DCI format(s) on the first carrier after receiving the reconfiguration message.
