Patent number: 8094638Abstract: An embodiment of the present invention uses estimates of delay spreads of transmissions from user equipments (UEs) to a NodeB to determine a set of transmission parameters for the UEs reference signals. In an exemplary embodiment, the transmission parameters for reference signals include cyclic shifts. Thus, embodiments include a set of allocated cyclic shift values that are tailored to the delay spreads. The set of allocated cyclic shift values are used by a corresponding set of UE being served by a NodeB to form references signals. Each UE uses the allocated cyclic shift to form its reference signal by applying the cyclic shift to a modified reference sequence. The modified reference sequence can be generated from a Constant-Amplitude-Zero-Auto Correlation (CAZAC) sequence. The set of allocated cyclic shift values can be updated periodically to account for changes of delay spreads, which can be caused by physical movements of the set of UEs.Type: GrantFiled: August 15, 2007Date of Patent: January 10, 2012Assignee: Texas Instruments IncorporatedInventors: Tarik Muharemovic, Aris Papasakellariou

Patent number: 8094765Abstract: Data is communicated through two separate circuits or circuit groups, each having clock and mode inputs, by sequentially reversing the role of the clock and mode inputs. The data communication circuits have data inputs, data outputs, a clock input for timing or synchronizing the data input and/or output communication, and a mode input for controlling the data input and/or output communication. A clock/mode signal connects to the clock input of one circuit and to the mode input of the other circuit. A mode/clock signal connects to the mode input of the one circuit and to the clock input of the other circuit. The role of the mode and clock signals on the mode/clock and clock/mode signals, or their reversal, selects one or the other of the data communication circuits.Type: GrantFiled: November 15, 2010Date of Patent: January 10, 2012Assignee: Texas Instruments IncorporatedInventor: Lee D.
