Abstract: PROBLEM TO BE SOLVED: To provide a method and system for providing hard handoffs between high-speed cells.SOLUTION: A mobile station transmits a plurality of channels including a pilot channel and at least one information channel. A base station determines the adequacy of the transmission energy of a reverse link signal in accordance with received energy of a reverse link pilot signal. Pilot channel transmission power is retained at a level prior to a frequency search excursion, while increasing the transmission energy of at least one other channel transmitted by the mobile station. In addition, when the mobile station is not capable of increasing the transmission energy of all of the information channels, the mobile station generates a ranking of the importance of the different information channels and selectively increases the transmission power of those channels.

Abstract: PROBLEM TO BE SOLVED: To quickly acquire synchronization of a signal in WCDMA communication system.
SOLUTION: A method is provided for utilizing variable duration sample accumulation, validity testing of decoder estimates, and parallel decoding of multiple synchronization signals within a PERCH channel. A receiver accumulates the samples necessary to reliably determine slot timing. Until slot timing estimates pass a validity test, samples are accumulated for frame timing estimates. Until frame timing estimates pass a validity test, samples are analyzed so as to determine the pilot offset of the channel.

Abstract: PROBLEM TO BE SOLVED: To provide a technique for reducing overhead system information between nodes and user equipment (UE).SOLUTION: Among the carriers, it is beneficial to have some special carriers designated by configurations in order to provide synchronization, system information, paging, data and control for multi-carrier enabled UE. 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 UE for access, synchronization, broadcast, and new control region within data regions of the legacy terminals. Coordination between nodes for selecting anchor carriers that mitigate interference and for transmit power control for non-anchor carriers provide further network performance advantages.

Abstract: PROBLEM TO BE SOLVED: To provide techniques for performing calibration and beamforming in a wireless communication system.SOLUTION: A node B may periodically perform calibration in each calibration interval with a set of UEs to obtain a calibration vector for the node B. The node B may apply the calibration vector to account for mismatches in the responses of the transmit and receive chains at the node B. The node B may perform beamforming to a UE by taking into account gain imbalance for multiple antennas at the UE. The node B may determine a precoding matrix for beamforming by taking into account gain imbalance due to (i) different automatic gain control (AGC) gains for receive chains at the UE, (ii) different power amplifier (PA) gains for transmit chains at the UE, and/or different antenna gains for multiple antennas at the UE.
