摘要： PROBLEM TO BE SOLVED: To provide a technique for transmitting variable transmission in a wireless communication system. SOLUTION: Physical channels to be sent in a super-frame are identified and allocated to time slots in the super-frame. The coding and modulation for each physical channel are selected based on its capacity. The data for each physical channel is selectively encoded based on an outer code rate, e.g., for a Reed-Solomon code, and further encoded based on an inner code rate, e.g., for a Turbo code. The encoded data for each physical channel is mapped to modulation symbols based on a selected modulation scheme. The modulation symbols for each physical channel are further processed (e.g., OFDM modulated) and multiplexed onto the time slots allocated to the physical channel. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for channel estimation in a wireless communication system operating on a given frequency band.SOLUTION: Resource allocation for a transmission to a wireless device is provided. A frequency band 400 is partitioned into at least two contiguous subbands. A determination is made whether it is desirable to transmit in a single subband or in more than one subband (404, 408, 412, 416). The transmission is assigned either to occur in the single subband or to operate in more than one subband. If the transmission is restricted to one subband, the hop pattern is also restricted to subcarriers within the particular subband.

摘要： PROBLEM TO BE SOLVED: To provide efficient pilot transmission system for multi-antenna communication systems.
SOLUTION: In one pilot transmission system, a first set of T scaled pilot symbols is generated with a first training vector and transmitted (e.g., continuously) from T transmit antennas, where T>1. If MIMO receiver(s) are to be supported by the system, then at least T-1 additional sets of T scaled pilot symbols are generated with at least T-1 additional training vectors and transmitted from the T transmit antennas. The training vectors are for different (e.g., orthogonal) spatial directions. Each MISO receiver can estimate its MISO channel based on the first set of scaled pilot symbols. Each MIMO receiver can estimate its MIMO channel based on the first and additional sets of scaled pilot symbols.

摘要： PROBLEM TO BE SOLVED: To provide a technique for adjusting a transmit power to alleviate both of an in-sector interference for a service base station and an inter-sector interference for a neighbor base station. SOLUTION: The amount of inter-sector interference caused by a terminal is approximately estimated based on a whole interference observed by each neighbor base station, channel gains relating to a service base station and a neighbor base station, and a current transmit power level. When a high interference is observed by the neighbor base station, the transited power is decreased and otherwise increased. When the terminal is situated closer to the neighbor base station that observes the high interference and/or the current transmit power level is higher, the transmit power is adjusted to a larger quantity and/or more frequently. By limiting a received SNR relating to the terminal within a tolerable SNR range, the in-sector interference is maintained within a tolerable level. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide techniques to manage interference for broadcast services and soft handoff in a wireless frequency hopping communication system (e.g., an OFDMA system). SOLUTION: In a first scheme, an FH function (r, T) is used for soft-handoff users, an FH function (k, T) is used for users not in soft handoff in each sector, and the FH function (k, T) is modified to be orthogonal to the FH function (f) (r, T), if and when it becomes necessary. In a second scheme, the FH function (r, T) used for soft-handoff users is defined to be orthogonal to or have low correlation with the FH function (k, T) used for users not in soft handoff in each sector Si, so that the modification of the FH function (k, T) is not needed. The FH function (k, T) for each sector is defined so as to be pseudo-random, with respect to the FH functions (k, T) for other sectors. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a system and method for enabling multiple transmitters to share a single code division multiplexed (CDM) or code division multiple access (CDMA) channel, using orthogonal waveforms. SOLUTION: A set of orthogonal channelizing codes Wi(t) is generated, and each transmitter is allocated orthogonal channelizing codes and pseudo-noise polynominals in a predetermined manner. The transmitters channelize each user signal using an orthogonal channelizing code Wi(t), and spread each user signal using a pseudo-noise (PN) spreading code. Each transmitter employs the same PN spreading codes and time offsets. Additionally, neither a single orthogonal channelizing code is assigned to more than one transmitter, during the period they are sharing a CDM channel. The spread signals are summed at each transmitter prior to transmission as a composite signal. The offsets and the frequencies of the signals are corrected in advance. COPYRIGHT: (C)2005,JPO&NCIPI
