Abstract: SYSTEMS AND METHODOLOGIES ARE DESCRIBED THAT FACILITATE EFFICIENTLY INDICATING PARAMETER(S) ASSOCIATED WITH A BASE STATION UTILIZING SYNCHRONIZATION SIGNALS IN A WIRELESS COMMUNICATION ENVIRONMENT. FOR INSTANCE, RELATIVE LOCATIONS OF A PSC AND A SSC IN A RADIO FRAME (200, 300) CAN BE A FUNCTION OF A PARAMETER. FURTHER, A PSC SEQUENCE UTILIZED TO GENERATE PSCS CAN BE SELECTED BASED UPON A PARAMETER. MOREOVER, INCLUSION OR EXCLUSION OF PSCS FROM A RADIO FRAME (200, 300) CAN BE A FUNCTION OF A PARAMETER. ADDITIONALLY OR ALTERNATIVELY, PSEUDO RANDOM SEQUENCE MAPPINGS (E.G., TO CELL IDS, TONE LOCATIONS) CAN BE A FUNCTION OF A PARAMETER. EXAMPLE PARAMETERS CAN BE WHETHER THE BASE STATION (102, 402, 1102, 1210, 1304) IS PART OF A TDD OR A FDD SYSTEM, WHETHER THE RADIO FRAME (200, 300) EMPLOYS FS1 OR FS2, WHETHER THE BASE STATION (102, 402, 1102, 1210, 1304) IS ASSOCIATED WITH A MACRO OR A FEMTO CELL, OR WHETHER THE BASE STATION IS ASSOCIATED WITH A UNICAST OR A MULTICAST SYSTEM.

Abstract: MULTIPLE DOWNLINK (DL) AND UPLINK (UL) CARRIERS CAN ENHANCE WIRELESS COMMUNICATION BETWEEN NODES AND USER EQUIPMENT (UE) (102). AMONG THE CARRIERS, IT IS BENEFICIAL TO HAVE SOME SPECIAL, BY CONFIGURATION DESIGNATED CARRIERS TO PROVIDE SYNCHRONIZATION, SYSTEM INFORMATION, PAGING, DATA AND CONTROL FOR MULTI-CARRIER ENABLED UES (102). THEREBY, OVERHEAD SYSTEM INFORMATION CAN BE REDUCED. FOR INSTANCE, SYNCHRONIZATION AND PAGING FOR A CERTAIN CELL ARE NOT PROVIDED ON ALL CARRIERS. A CARRIER CAN PROVIDE BACKWARD COMPATIBILITY FOR SINGLE CARRIER UES (102) FOR ACCESS, SYNCHRONIZATION, BROADCAST, AND NEW CONTROL REGION WITHIN THE DATA REGION OF THE LEGACY TERMINALS. COORDINATION BETWEEN NODES FOR SELECTING ANCHOR CARRIERS (106A, 106B, 136, 138) THAT MITIGATE INTERFERENCE AND FOR TRANSMIT POWER CONTROL FOR NON-ANCHOR CARRIERS (110A-110C, 140, 142) PROVIDE FURTHER NETWORK PERFORMANCE ADVANTAGES.

Abstract: PROVIDING A CODING SCHEME FOR WIRELESS COMMUNICATION DOWNLINK REFERENCE SIGNALS IS DESCRIBED HEREIN. BY WAY OF EXAMPLE, A DEDICATED REFERENCE SIGNAL IS MAPPED TO RESOURCES OF A WIRELESS CHANNEL AS A FUNCTION OF AN IDENTIFIER (ID) OF A CELL IN WHICH THE REFERENCE SIGNAL IS TRANSMITTED. THE FUNCTION CAN BE SIMILAR TO MAPPING FUNCTIONS EMPLOYED FOR COMMON REFERENCE SIGNALS, OR CAN BE DISTINCT FROM SUCH FUNCTIONS. AS ONE EXAMPLE OF THE LATTER, A DEDICATED REFERENCE SIGNAL MAPPING FUNCTION CAN BE SHIFTED IN TIME OR FREQUENCY WITH RESPECT TO THE COMMON REFERENCE SIGNAL MAPPING FUNCTION. BY EMPLOYING A MAPPING FUNCTION BASED ON CELL ID (210, 536), NOISE CAUSED BY CONCURRENT TRANSMISSION OF REFERENCE SIGNALS CAN BE MITIGATED IN A MANNER READILY DETERMINED BY TERMINALS IN A WIRELESS NETWORK (1500).

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: Techniques for sending multiple-input multiple-output (MIMO) transmissions in wireless communication systems are described. In one design, a transmitter sends a first reference signal via a first link, e.g., a cell-specific reference signal via the downlink. The transmitter receives channel quality indicator (CQI) information determined by a receiver based on the first reference signal. The transmitter also receives a second reference signal from the receiver via a second link, e.g., a sounding reference signal via the uplink. The transmitter obtains at least one MIMO channel matrix for the first link based on the second reference signal. The transmitter determines at least one precoding matrix based on the at least one MIMO channel matrix, e.g., in accordance with ideal eigen-beamforming or pseudo eigen-beamforming. The transmitter then sends a data transmission to the receiver based on the at least one precoding matrix and the CQI information.

Abstract: Techniques for sending traffic data and control information in a wireless communication system are described. In one design, a transmitter (e.g., a Node B or a UE) may perform beamforming to send traffic data on M layers based on a precoding matrix, where M may be one or greater. The transmitter may also perform beamforming to send control information on up to M layers based on the same precoding matrix used for the traffic data. The transmitter may send the beamformed traffic data on a first physical channel and may send the beamformed control information on a second physical channel. The transmitter may multiplex the beamformed traffic data and the beamformed control information using time division multiplexing (TDM) or frequency division multiplexing (FDM).
