Abstract: SYSTEMS, METHODOLOGIES, AND DEVICES ARE DESCRIBED THAT CAN FACILITATE BANDWIDTH EFFICIENT NON-COHERENT SIGNALING FOR UPLINK CONTROL CHANNEL TRANSMISSIONS. A COMMUNICATION DEVICE (116, 122, 800, 906, 1050, 102, 902, 1010) (E.G., A MOBILE DEVICE, BASE STATION) CAN BE CONFIGURED TO UTILIZE OR GENERATE A SET OF COMPLEX ORTHOGONAL CODEWORDS TO FACILITATE TRANSMISSION OF CONTROL CHANNEL INFORMATION USING NON-COHERENT SIGNALING IN A BANDWIDTH EFFICIENT MARINER. A COMPLEX ORTHOGONAL CODEWORD SET CAN COMPRISE A FIRST SUBSET OF CODEWORDS WHERE SUCH CODEWORDS HAVE A DESIRABLE CROSS-CORRELATION PROPERTY AND ANOTHER SUBSET(S) OF CODEWORDS THAT CAN INCLUDE EXPURGATED CODEWORDS, WHERE THE EXPURGATED CODEWORDS CAN INCLUDE DISCARDED CODEWORDS AND/OR CODEWORD PAIRS THAT PRODUCE A WORST-CASE CROSS-CORRELATION PROPERTY. THE CODEWORD SET AND SUBSETS ARE DETERMINED BASED AT LEAST IN PART ON A PREDEFINED CODEWORD CRITERION (1106). A PORTION OF THE DISCARDED CODEWORDS CAN BE USED FOR OTHER PURPOSES, SUCH AS ERASURE DECODING, INTERFERENCE-LEVEL ESTIMATION, AND/OR MULTI-MODE CONTROL CHANNEL OPERATION.

Abstract: Techniques for sending control information in a wireless communication system are described. In an aspect, a UE spreads control information across frequency with a DFT and across time with an orthogonal sequence to obtain output data for the control information. In one design, the UE receives codewords for N HARQ processes in N downlink subframes, determines an ACK value for each HARQ process, codes N ACK values for the N HARQ processes to obtain ACK information, generates output data for the ACK information, and sends the output data in one of M uplink subframes. In another aspect, first control information is processed based on a first coding and multiplexing scheme utilizing code division multiplexing in time and frequency domains. Second control information is processed based on a second coding and multiplexing scheme utilizing code division multiplexing in time domain and spreading in frequency domain.

Abstract: To support cell search, multiple (e.g., two) synchronization transmissions are sent in a frame with non-uniform spacing. Information is conveyed via the non-equal distances between consecutive synchronization transmissions. Multiple levels of non-uniform spacing may be used to convey different types of information. In one design, the multiple synchronization transmissions are sent in different subframes of a frame, and each synchronization transmission is sent in one of multiple symbol periods in a respective subframe. The synchronization transmissions may be sent in non-evenly spaced subframes to convey frame boundary. One synchronization transmission may be sent in one of multiple possible symbol periods depending on the information, e.g., a particular group of cell IDs, being conveyed. The distances between synchronization transmissions may also be used to convey cyclic prefix length. A secondary synchronization transmission carrying a cell ID may be sent at a predetermined offset from one of the multiple synchronization transmissions.
