Abstract: PROBLEM TO BE SOLVED: To determine use of receive diversity in a mobile station. SOLUTION: A control system 210 determines a demand level about usage of a communicating resource. A sender transmits a message, which shows the usage of receive diversity in the mobile station based on the determined demand level. After receiving one channel, the receiver 200 determines a transmitting power level of the channel for being at a lower or upper transmit power level limit. Based on the determined transmitting power level, the control system 210 controls the receive diversity by choosing the number of receiver chains 290. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To improve utilization of the forward link and to decrease the transmission delay through high rate packet data transmission in a data communication system capable of variable rate transmission. SOLUTION: Data transmission on the forward link is time-multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for performing code assignment in a spread spectrum wireless communication system, to which large area synchronized-code division multiple access (LAS-CDMA) protocol is incorporated, and to determine a set of LS codes based on window size without interference.
SOLUTION: In a tree structure, the window size without interference and the LS codes correspond with each other. A subset of LS codes is formed in a window without interference so that it may have mutual correlation of zero. The subset is assigned to a cell in its neighborhood in the system in order to decrease the interference among neighboring cells. A controller determines the subset which will be assigned to the cells in the system.

Abstract: PROBLEM TO BE SOLVED: To reduce interference caused by concurrent broadcast transmissions from multiple transmitters.SOLUTION: Synchronized broadcast transmits the same broadcast content using the same waveform from multiple transmitters. The transmitters each apply the same spreading code for broadcast transmissions. In a spread-spectrum communication system having a time division multiplexed forward link, a synchronized broadcast transmission is inserted into a broadcast slot. An Orthogonal Frequency Divisional Multiplex (OFDM) waveform is used for the synchronized broadcast transmission. An OFDM receiver is then used to process the received synchronized broadcast transmission. A broadcast Pseudo-random Noise (PN) code is used for use by multiple transmitters. An equalizer is then used to estimate the synchronized broadcast transmission.

Abstract: PROBLEM TO BE SOLVED: To provide techniques to improve an acquisition process in a spread spectrum environment.SOLUTION: Signals from various CDMA systems are spread with various sets of PN sequences, and the PN sequences of each set are uncorrelated to the PN sequences of the other sets. By using uncorrelated PN sequences, the likelihood of detecting a pilot signal from an undesired system is reduced or minimized, and the mean time to acquire the pilot signal from a desired system is improved. A mobile station acquires the pilot signal by processing a received signal with a first set of the PN sequences corresponding to a first hypothesis of acquired particular signal. When the acquisition of the pilot signal is a failure, a second set of the PN sequences corresponding to a second hypothesis is selected and the received signal is processed. The PN sequences in the second set are uncorrelated to the PN sequences in the first set.

Abstract: PROBLEM TO BE SOLVED: To optimize resource allocation to serve different types of data flows in wireless communication.
SOLUTION: Data metrics are calculated for data in a plurality of queues, each queue corresponding to a different data flow in a wireless communication system. The data metrics are used to determine a separate transmission metric for each of a plurality of possible transmission formats. The transmission metric for a given transmission format is dependent on the data metrics corresponding to allocated data for the given transmission format. A transmission format that has an optimum transmission metric is selected, and the data is transmitted on the forward link in accordance with the selected transmission format.

The control system 210 controls the reception diversity by selecting the number of receiver chains 290 based on the determined transmission power level. In another aspect, the receiver 200 receives one channel and determines one channel condition of the channel and the duration of the channel condition.
