    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 data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations.

    摘要： Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.

    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.
