    摘要： A UE may store received samples of a wireless signal at cx1 to reduce memory usage, but then may correlate those samples with cx2 timing hypotheses to improve performance. The received sequence is resampled at cx2 instead of cx1. The UE still performs the correlation of the cx2 timing hypotheses for the performance gain, but the reference waveform is resampled with cx2 time offset. A Fast Fourier Transform (FFT) may be taken of the received and reference waveforms. In the frequency domain, resampling may be performed by multiplying the FFT of the reference waveform by a phase ramp—a pointwise multiplication in the frequency domain with a constant magnitude sequence whose phase varies linearly.

    摘要： Techniques for centralized control of relay operation are described. In an aspect, a designated network entity (e.g., a base station or a network controller) may control the operation of relay stations within its coverage area. The network entity may select certain user equipments (UEs) to be relay UEs that can serve as relay stations for other UEs, e.g., based on pathloss between the UEs and a base station, the locations of the UEs, battery power levels of the UEs, fairness considerations, etc. The network entity may also select a specific relay UE to serve as a relay station for a client UE desiring to communicate with a base station, e.g., based on pilot measurements from relay UEs for the client UE. The network entity may also control transmission of discovery pilots by relay UEs and/or client UEs for relay detection.

    摘要： Methods, systems, apparatus and computer program products are provided to facilitate power control in wireless communication systems. A cell that is experiencing excessive interference conditions may generate an over-the-air overload indicator indicative of interference conditions at the cell. The over-the-air overload indicator is received by one or more user equipment in a neighboring cell. In response, the user equipment determines adjustments to its transmit power that reduce and/or eliminate the interference. This determination may be carried out by the user equipment, by the serving base station, or through cooperation between the user equipment and the serving base station. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.

    摘要： Techniques for performing power control of multiple channels sent using multiple radio technologies are described. The transmit power of a reference channel, sent using a first radio technology (e.g., CDMA), is adjusted to achieve a target level of performance (e.g., a target erasure rate) for the reference channel. The transmit power of a data channel, sent using a second radio technology (e.g., OFDMA), is adjusted based on the transmit power of the reference channel. In one power control scheme, a reference power spectral density (PSD) level is determined based on the transmit power of the reference channel. A transmit PSD delta for the data channel is adjusted based on interference estimates. A transmit PSD of the data channel is determined based on the reference PSD level and the transmit PSD delta. The transmit power of the data channel is then set to achieve the transmit PSD for the data channel.

    摘要： Aspects are disclosed for sequencing and correlating a positioning reference signal. A set of reference symbols associated with a reference signal are allocated, and a base sequence is generated. An extended sequence, which includes the set of reference symbols, is then provided according to the base sequence. The extended sequence is then transmitted in a sub-frame designated as an idle period. A sequence of reference symbols is received from a base station during an idle period of the base station. A replicated sequence of reference symbols is generated, and a correlation is ascertained between a subset of the received sequence of reference symbols and a corresponding subset of the replicated sequence of reference symbols. The received sequence of reference symbols is then identified according to the correlation.

    摘要： Techniques for selectively transmitting a power decision pilot are described. The power decision pilot may be indicative of the transmit power to use for data transmission in a future time interval. The power decision pilot may be transmitted when sufficiently beneficial for channel quality estimation or omitted otherwise. Whether or not to transmit the power decision pilot may be determined based on system type (e.g., heterogeneous or homogeneous system), the presence or absence of a dominant interferer, whether a reduce interference request is received, etc. For example, a base station may transmit a power decision pilot if it causes high interference to a non-served terminal, if a served terminal observes high interference from a neighbor base station, if the base station receives a reduce interference request from a non-served terminal, etc. The power decision pilot may be transmitted if a determination is made to transmit the pilot or omitted otherwise.
