    摘要: A base station includes a precoding processor that conducts the same precoding process on a control channel and a reference signal, a controller that sets a plurality of regions including a region in which the reference signal is placed and a region in which the control channel is potentially placed. Different precoding processes are used among different regions. A transmit processor uses resources in a region to transmit the control channel and the reference signal. A mobile station device includes a controller that sets a region on the basis of announced information from the base station device, a propagation channel estimator that averages propagation channel variation estimation values from a plurality of reference signals within the region, and a control channel detector that uses the averaged propagation channel estimation values to detect the control channel that includes control information addressed to the mobile station device.

    摘要: A base station configured for coordinating uplink resource allocation is described. The base station includes a processor and instructions stored in memory. The base station generates uplink resource allocation information for one or more wireless communication devices. The uplink resource allocation information is sent to one or more base stations. The base station allocates uplink resources based on the uplink resource allocation information. The base station sends an assignment to one or more wireless communication devices based on the uplink resource allocation information.

    摘要: A method for detecting a specific timing from a synchronization channel is described. A signal with a known sequence is received. Two or more correlation values between the received signal and the known sequence are calculated at two or more positions. The two or more correlation values are compared. A determination is made whether the position of the known sequence has been shifted based on the comparison. A specific timing of a synchronization channel is detected based on the determination.

    摘要: A method for transmitting control information may include providing formatting rules that define a format for transmission of the control information to a base station via a control signaling channel. The control information may include a channel quality indicator (CQI), an acknowledgement/non-acknowledgement (ACK/NACK), a pre-coding matrix indicator (PMI), and rank information. The method may also include providing combination rules as part of the formatting rules. The combination rules may define how the CQI, the ACK/NACK, the PMI, and the rank information are combined for transmission on the control signaling channel. The method may also include transmitting the control information to the base station via the control signaling channel in accordance with the defined formatting rules.
