Abstract: Techniques for sending messages for system access are described. In one aspect, a user equipment (UE) sends a first message with power headroom and/or buffer size information for system access. 5 A Node B determines at least one parameter (e.g., a resource grant, power control information, etc.) based on the power headroom and/or buffer size information. The Node B sends a second message with the parameter(s). The UE sends a third message based on the parameter(s), e.g., with uplink resources indicated by the resource grant, with transmit power determined based on the power control information, etc. In another aspect, the UE sends a radio environment report in the third 10 message. The report may be used to select a cell and/or a frequency for the UE. In yet another aspect, the second message includes power control information, and the UE sends the third message based on the power control information.

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: Methods and apparatuses are described in which an unlicensed spectrum is used for Long Term Evolution (LTE) communications. A first method includes broadcasting beacon signals in an unlicensed spectrum at predetermined times from an evolved Node B (eNB). A second method includes receiving beacon signals broadcast in an unlicensed spectrum at predetermined times from an eNB. The beacon signals may include downlink signals identifying the eNB and at least one associated attribute of the eNB.

Abstract: SYSTEMS AND METHODOLOGIES ARE DESCRIBED HEREIN THAT FACILITATE CONTROL AND DATA MULTIPLEXING FOR UPLINK (UL) MULTIPLE-INPUT-MULTIPLE-OUTPUT (MIMO) COMMUNICATION WITHIN A WIRELESS COMMUNICATION SYSTEM (100). AS DESCRIBED HEREIN, A DEVICE CONDUCTING UPLINK MIMO COMMUNICATION IN A WIRELESS COMMUNICATION SYSTEM (100) CAN MULTIPLEX CONTROL SIGNALING AND DATA ACROSS ONE OR MORE OF A PLURALITY OF LAYERS (E.G., CORRESPONDING TO SPATIAL LAYERS, CODEWORDS, ETC.) ASSOCIATED WITH AN UPLINK TRANSMISSION. TECHNIQUES ARE DESCRIBED HEREIN FOR SELECTING (706) LAYERS OF A TRANSMISSION ON WHICH TO SCHEDULE CONTROL SIGNALING AND SELECTING OFFSETS TO APPLY TO THE CONTROL SIGNALING SCHEDULED ON SELECTED LAYERS. FURTHER, TECHNIQUES ARE DESCRIBED HEREIN FOR LEVERAGING A MULTI-LAYER TRANSMISSION TO INCREASE THE EFFICIENCY OF ACKNOWLEDGEMENT COMMUNICATION. IN ADDITION, TECHNIQUES ARE DESCRIBED FOR SELECTING A MODULATION AND CODING SCHEME (MCS) TO APPLY TO CONTROL SIGNALING THAT IS COMBINED WITH DATA IN AN UPLINK MULTI-LAYER TRANSMISSION.

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 TRANSMISSION 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.

Abstract: TECHNIQUES FOR TRANSMITTING DATA USING A COMBINATION OF EXPLICIT CYCLIC DELAY AND IMPLICIT CYCLIC DELAY ARE DESCRIBED. A TRANSMITTER MAY PERFORM (612) FIRST PROCESSING FOR CYCLIC DELAY DIVERSITY (OR EXPLICIT CYCLIC DELAY PROCESSING) BASED ON A FIRST SET OF CYCLIC DELAY VALUES KNOWN TO A RECEIVER. THE TRANSMITTER MAY PERFORM PRECODING BASED ON A PRECODING MATRIX EITHER BEFORE OR AFTER THE EXPLICIT CYCLIC DELAY PROCESSING. THE TRANSMITTER MAY PERFORM (616) SECOND PROCESSING FOR CYCLIC DELAY DIVERSITY (OR IMPLICIT CYCLIC DELAY PROCESSING) BASED ON A SECOND SET OF CYCLIC DELAY VALUES UNKNOWN TO THE RECEIVER. THE TRANSMITTER MAY PERFORM BOTH EXPLICIT AND IMPLICIT CYCLIC DELAY PROCESSING FOR DATA AND MAY PERFORM ONLY IMPLICIT CYCLIC DELAY PROCESSING FOR PILOT. ONE ENTITY MAY SELECT THE FIRST SET OF CYCLIC DELAY VALUES AND INFORM THE OTHER ENTITY. THE TRANSMITTER MAY AUTONOMOUSLY SELECT THE SECOND SET OF CYCLIC DELAY VALUES WITHOUT INFORMING THE RECEIVER.

Abstract: A METHOD FOR A WIRELESS COMMUNICATION INCLUDES RECEIVING OR STORING A PEAK TO AVERAGE (PAR) BACK OFF VALUE; AND APPLYING THE PAR BACK OFF VALUE TO DETERMINE THE TRANSMISSION POWER AND RATE FOR SIMO AND MIMO TRANSMISSIONS. IN ONE ASPECT, THE PAR BACK OFF VALUE IS AT LEAST PARTIALLY BASED ON MODULATION TYPE. IN ANOTHER ASPECT, THE PAR BACK OFF VALUE IS MORE FOR HIGHER ORDER QAM THAN FOR QPSK. THE POWER ALLOCATION ALGORITHM FOR DIFFERENT UL MIMO SCHEMES IS DESCRIBED AS FOLLOWS. FOR MIMO WITHOUT ANTENNA PERMUTATION (E.G. PER ANTENNA RATE CONTROL), DIFFERENT PAR BACK OFFVALUES ARE CONSIDERED FOR DIFFERENT DATA STREAMS. FOR MIMO WITH ANTENNA PERMUTATION OR OTHER UNITARY TRANSFORMATION SUCH AS VIRTUAL ANTENNA MAPPING OR PRECODING, THE PAR BACK OFF ARE DETERMINED BASED ON COMBINED CHANNEL. THE TRANSMISSION DATA RATE DEPENDS ON POWER AND ALSO THE RECEIVER ALGORITHMS SUCH AS A MMSE RECEIVER OR MMSE-SIC RECEIVER.

Abstract: SYSTEMS AND METHODOLOGIES ARE DESCRIBED THAT PROVIDE TECHNIQUES FOR EFFICIENT CELL SEARCH IN A WIRELESS COMMUNICATION SYSTEM. IN ONE ASPECT, A FREQUENCY REUSE PATTERN CAN BE GENERATED BY APPLYING FREQUENCY SHIFTS TO REFERENCE SIGNALS TRANSMITTED FROM CELLS THAT PROVIDE COVERAGE FOR A NODEB BASED ON CELL IDS OR CELL GROUP IDS FOR THE CELLS. THE FREQUENCY SHIFTS APPLIED TO REFERENCE SIGNALS CAN THEN BE UTILIZED AS A BASIS FOR MULTIPLEXING REFERENCE SIGNALS FROM DIFFERENT CELLS USING FREQUENCY DIVISION MULTIPLEXING (FDM) OR A COMBINATION OF FDM AND OTHER MULTIPLEXING TECHNIQUES. OTHER ADJUSTMENTS TO REFERENCE SIGNALS TRANSMITTED FROM RESPECTIVE CELLS, SUCH AS TRANSMIT POWER ADJUSTMENTS, CAN FURTHER BE MADE TO IMPROVE DETECTION PERFORMANCE.

Abstract: Systems and methodologies are described that facilitate selecting frequency for transmitting control channel format indicator (CCFI) data such to identify a related cell. In one example, the CCFI data can be transmitted in an initial portion of frequency (such as an orthogonal frequency division 5 multiplexing (OFDM) symbol) in a time transmit interval (TTI). The CCFI data can be spread across the initial portion of frequency and be shifted to identify the transmitting cell. Additionally, the CCFI data can be scrambled to further identify the cell. The CCFI data can also be utilized to determine structure of subsequent control and/or data channels. - -o z U. z~ - 02 0%
