    摘要: A method and apparatus for neighbor discovery in a wireless communication system are disclosed. A neighbor seeking wireless transmit/receive unit (WTRU) may send a first beacon based on configuration information provided by the network. The neighbor WTRUs receive the first beacon and may send either a report to the network or send a second beacon to the neighbor seeking WTRU. The network may then provide neighbor WTRU information to the neighbor seeking WTRU. The neighbor discovery may be performed within a pre-defined group of WTRUs that is formed based on proximity to the WTRU and/or an attribute of the WTRU. The neighbor discovery procedure may be performed to find neighbor WTRUs in case where a WTRU fails to find any network. A neighbor list may be generated by the neighbor seeking WTRU by measuring reference signals transmitted by neighbor WTRUs on an uplink to the network.

    摘要: A method and apparatus for estimating a signal-to-interference ratio (SIR) are disclosed. A received signal includes signal energy on multiple basis functions. Desired signal energy in the received signal is transformed onto a first basis function with constant polarity. The desired signal energy is estimated by coherently averaging signal energy on the first basis function. A noise power is estimated by averaging signal energy on each basis function other than the first basis function and accumulating the averaged signal energy from the basis function other than the first basis function and scaling the accumulated signal energy to account for a noise estimate from the first basis function. An SIR is estimated by dividing the desired signal energy by the noise power.

    摘要: A method and apparatus for performing closed loop transmit power control of a fractional dedicated physical channel (F-DPCH) are disclosed. Transmit power control (TPC) symbols on an F-DPCH and common pilot channel (CPICH) symbols are received. A short term signal power estimate is calculated using the TPC symbols, and a short term noise power estimate is calculated using the CPICH symbols. A short term signal-to-interference ratio (SIR) on the F-DPCH is calculated. A long term signal power estimate and a long term noise power estimate are calculated using the TPC symbols. A long term SIR is calculated and compared to a TPC quality target. An SIR target is adjusted based on comparison of the long term SIR to the TPC quality target. The short term SIR is compared to the SIR target and a TPC command is generated based on comparison of the short term SIR to the SIR target.
