    摘要: Systems and methodologies are described that facilitate responding to overload indicators in a wireless communication environment. A non-serving base station can send an over-the-air (OTA) overload indicator (OI) and a backhaul OI. A UE can receive the OTA OI from the non-serving base station, generate a report based upon the OTA OI, and send the report to a serving base station. The serving base station can receive the report from the UE, and generate a power control command for the UE based at least in part upon the report. Moreover, the serving base station can generate the power control command for the UE further based upon the backhaul OI received from the non-serving base station. For example, the UE can be configured to ignore the OTA OI. By way of another example, the serving base station can cause the non-serving base station to inhibit sending the backhaul OI.

    摘要: Devices and methods are provided for implementing an over-the-air (OTA) broadcast of an overload indication to reduce interference levels at neighboring node(s). In one embodiment, the method involves receiving the OTA broadcast of the overload indication from a neighboring node. The method further involves performing transmit power control based upon the received overload indication to reduce Interference over Thermal (IoT) noise at the neighboring node (e.g., by adjusting the transmit power spectral density). Such a method may be performed, for example, by an access terminal or a small base node.

    摘要: User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

    摘要: Providing for improved error control signaling in wireless communications is disclosed herein. By way of example, multiple transmissions can be conducted for a HARQ process prior to a scheduled feedback signal on the HARQ process, causing a receiving device to combine the multiple transmissions, rather than treat them as separate transmissions. In this manner, multiple transmissions can be employed to increase overall receive energy, without violating maximum transmit power constraints in a wireless communication. Further, these multiple transmissions can be configured based on prevailing signal strength at the receiving device, or based on processing capabilities of the receiving device, providing flexible protocols that can accommodate advanced as well as legacy UEs in wide range of wireless conditions.

    摘要: Techniques for transmitting UE-specific reference signals (UE-RSs) in a wireless network are described. In an aspect, a UE-RS may be transmitted in different manners depending on the number of layers used for data transmission. In one design, a cell may determine subcarriers for a UE-RS based on a frequency shift if data is transmitted on one layer and based on a predetermined set of subcarriers (with no frequency shift) if data is transmitted on multiple layers. In another aspect, a UE-RS may be transmitted on subcarriers determined based on a frequency shift for data transmission on multiple layers. In yet another aspect, a UE-RS may be transmitted from a plurality of cells to a UE for coordinated multi-point (CoMP). In yet another aspect, a UE-RS may be transmitted in a data section of a subframe including only the data section.

    摘要: Techniques for computing and reporting channel quality indication (CQI) are described. In an aspect, a plurality of CQI computation methods may be supported, and each CQI computation method may indicate how CQI should be computed. One CQI computation method may be selected for use. CQI may then be computed and reported in accordance with the selected CQI computation method. In an exemplary design, a user equipment (UE) may obtain a selected method for computing CQI, which may be chosen based on the UE capability and/or other factors. The selected method may specify (i) CQI computation for a specific codeword among a plurality of codewords or (ii) CQI computation by averaging signal quality across a plurality of layers used for transmission. The UE may compute CQI in accordance with the selected method, send the CQI to a base station, and receive data sent by the base station based on the CQI.
