Abstract: A synchronization signal format for a cell search method is proposed to reduce cell search complexity and cell search time. A synchronization signal is embedded with a unique sequence that is consecutively repeated multiple times in time domain. Different unique sequences represent different control information to be broadcasted from a base station to user equipments via synchronization signal transmissions. A two-stage cell search method is then applied in accordance with the synchronization signal format. In a first acquisition stage, a coarse location of the synchronization signal is acquired. In a second fine searching stage, the unique sequence is detected within a searching range of the coarse location.

Abstract: A method of beam administration in a cellular or wireless network is proposed. Cellular/wireless networks operating at Ka or higher frequency band require the use of directional antenna (or through array-based beamforming) to compensate for sever pathloss. Maintaining antenna pointing and tracking accuracy is essential in many phases of the communication process. By using uplink pilot signals for beam alignment/tracking, combined with switched beamforming at the UE and adaptive beamforming at the BS, an effective beam administration is achieved with reduced overhead, complexity, and cost.

Abstract: A beamforming system synchronization architecture is proposed to allow a receiving device to synchronize to a transmitting device in time, frequency, and spatial domain in the most challenging situation with very high pathloss. A periodically configured time-frequency resource blocks in which the transmitting device uses the same beamforming weights for its control beam transmission to the receiving device. A pilot signal for each of the control beams is transmitted in each of the periodically configured time-frequency resource blocks. The same synchronization signal can be used for all stages of synchronization including initial coarse synchronization, device and beam identification, and channel estimation for data demodulation.

Abstract: A method of maximum output power configuration with UE preference in carrier aggregation is provided. A UE configures multiple component carriers (CCs) with carrier aggregation for communicating with a serving base station in a mobile communication network. The UE determines channel condition of multiple serving cells over the corresponding multiple CCs. The UE then determines maximum output power for each CC based at least in part on the corresponding channel condition of each CC. Finally, the UE transmits power headroom report (PHR) for each CC to the serving base station, wherein the PHR is calculated based on the determined maximum output power. As a result, the reported PH information is channel condition dependent, which can be used by eNB for facilitating better transmission scheduling.
