摘要： A mobile device estimates a data symbol from a received signal by using one or more interference cancellation algorithms. For one interference cancellation algorithm, the mobile device calculates (302) a Channel State Information (CSI) of an interfering sector and calculates (304) a CSI of a serving sector at a different time. The mobile device then determines (310) a correction factor to the CSI of the interfering sector by, for example, estimating a Doppler speed and a time difference between a first time interval like a preamble symbol and a second time interval like any symbol of interest in the data zone. Using the correction factor, the mobile device updates outdated interference information. The mobile device can cancel interference in the received signal distorted by co-channel interference by using the updated interference information. Also, the mobile device can be configured to combine results of multiple interference cancellation algorithms based on the applicability of the individual interference cancellation algorithms in particular scenarios.

摘要： A downlink subframe on a single downlink carrier supports physical layer acknowledgment signaling for multiple physical uplink shared channel (PUSCH) transmissions. The physical layer acknowledgement signaling may take the form of physical hybrid ARQ indicator channel (PHICH) signaling. A base unit reserves resource elements groups (REGs) for default PHICH signaling of default PUSCH transmissions. The base unit reserves control channel elements (CCEs) for physical downlink control channel (PDCCH) signaling. A CCE contains multiple interleaved REGs. The base unit takes any unreserved CCEs and maps those CCEs for physical layer acknowledgement signaling of additional PUSCH transmissions.

摘要： A relay design backward compatible with existing wireless communication networks. The invention provides details of apparatus and methods to enable operation of inband relays. Using a grant-based inhibit mechanism, a Relay and an eNB can efficiently cooperate to improve the performance by allowing one of either UE or the Relay to transmit on the uplink. Similarly, the UE overrides any pre-determined schedule (i.e., absence of Reference Signals) by searching for a scheduling grant and if the UE find the scheduling grant, the UE can assume that the Relay has overridden the pre-determined schedule temporarily.

摘要： A receiver with DFT based channel estimation having good noise suppression for both high and low signal-to-noise ratios providing advantages over conventional DFT estimators and Minimum-Mean-Square-Error (MMSE) estimators. The use of MMSE may be incorporated for estimation at the band edges providing further improvements. The received signal in the time domain, is transformed to the frequency-domain received signal via an N-point FFT (501). The frequency-domain received signal at the pilot locations is then used to obtain a "noisy" channel estimates at the pilot subcarriers by dividing the known pilot symbols in (503). Uniformly spaced pilots are assumed over a window of usable subcarriers. Padding is applied to the initial channel estimates at both sides of the band to account for unused subcarriers such as guard spacing. Weighting factors during power estimation may take into account various noise characteristics such as combinations of known and time-limited noise power characteristics.
