Latest Patents

One of Tarkiainen’s latest patents, “Method, Apparatus and Computer Program for User Equipment Access Channel Procedures,” describes ways for user equipment to retry access to a wireless network through a random access channel. The method uses preambles containing signature sequences and specifies that the retry’s transmit power is no greater than the power used for the initial attempt. The patent describes variations in how the signature sequences and transmit powers are selected.

Another patent, “Method and Apparatus for Timing Adjustment for Uplink Synchronous Transmission in Wide Code Division Multiple Access,” concerns uplink synchronization in UTRA FDD systems. It describes using time-alignment bits in place of transmit power commands to indicate whether a signal arrives at a base station earlier or later than desired. The user equipment can adjust its transmission timing based on accumulated alignment indications.
