摘要： According to an embodiment a user equipment UE transmits uplink control signals using one or more chunks of uplink frequency spectrum that contain a simultaneous uplink shared channel; and for the case where there is no simultaneous uplink shared channel available, the UE transmits uplink control signals using only a single chunk of uplink frequency spectrum. In various embodiments the control signals are ACK/NACK control signals transmitted on an uplink control channel, the uplink shared channel comprises a chunk-specific uplink control channel, and each chunk comprises a component carrier of a LTE-A system. Downlink assignment index bits may be included in a downlink grant to the UE which indicates how many chunks in total are allocated in a current downlink subframe. The UE can also use ACK/NACK control signal bundling over chunks in addition to either or both of chunk-specific ACK/NACK control signals or ACK/NAK control signal multiplexing.

摘要： This invention teaches a method for use in a wideband CDMA telecommunications system wherein the base station (BS) utilizes transmit antenna diversity. The method enables the user equipment (UE) to perform a channel estimate for channels received from two antennas of the base station (BS), and includes steps of: (a) computing an estimated phase difference between a common pilot channel and a dedicated pilot channel received from one antenna of the two antennas; and (b) determining the channel estimate by rotating a common pilot channel estimate according to the estimated phase difference, where the phase difference is computed as a complex coefficient between the common pilot channel and the dedicated pilot channel. In a second aspect this invention teaches a method for use in a transmit antenna diversity system for enabling the UE to verify an antenna phase shift previously signaled by the UE to the BS. This method includes a first step of: (a) exploiting prior knowledge of BS rotation angle by considering a vector x that includes all hypotheses for complex rotation coefficients of the BS with respect to all possible rotation angles, in accordance with a decision rule for an estimation of a complex rotation coefficient. A second step of the method evaluates a cost function of a hypothesis m by considering the prior knowledge.
