Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for performing power control of multiple channels sent using multiple radio technologies.SOLUTION: The transmit power of a reference channel, sent using a first radio technology (e.g., CDMA), is adjusted to achieve a target level of performance (e.g., a target erasure rate) for the reference channel. The transmit power of a data channel, sent using a second radio technology (e.g., OFDMA), is adjusted based on the transmit power of the reference channel. In one power control scheme, a reference power spectral density (PSD) level is determined based on the transmit power of the reference channel (1312). A transmit PSD delta for the data channel is adjusted based on interference estimates (1314). A transmit PSD of the data channel is determined based on the reference PSD level and the transmit PSD delta (1316). The transmit power of the data channel is then set to achieve the transmit PSD of the data channel (1318).

Abstract: PROBLEM TO BE SOLVED: To support a plurality of PC modes such as an up-down PC mode and an erasure-based PC mode.SOLUTION: One PC mode may be selected for use. A signal may be sent to indicate the selected PC mode. If an up-down PC mode is selected, then a base station estimates received signal quality for a terminal and sends PC commands to direct the terminal to adjust its transmit power. If an erasure-based PC mode is selected, then the base station sends erasure indications that indicate whether codewords received from the terminal are erased or non-erased. For both PC modes, the terminal adjusts its transmit power based on power control feedback (e.g., PC commands and/or erasure indications) to achieve a target level of performance (e.g., a target erasure rate for the codewords). The erasure indications may also be used for handoff.

解决方案：可以选择一种PC模式进行使用。 可以发送信号以指示所选择的PC模式。 如果选择了上下PC模式，则基站估计终端的接收信号质量并发送PC命令以指示终端调整其发射功率。 如果选择基于擦除的PC模式，则基站发送指示从终端接收的码字是否被擦除或不被擦除的擦除指示。 对于两种PC模式，终端基于功率控制反馈（例如，PC命令和/或擦除指示）调整其发射功率，以实现目标性能水平（例如，码字的目标擦除率）。 擦除指示也可用于切换。 版权所有（C）2012，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To control transmit power of terminals to reduce interference.SOLUTION: A terminal may send a first transmission (e.g., for pilot or signaling) on a reverse link, receive feedback (e.g., a power control command or an erasure indicator) for the first transmission, and adjust a reference power level based on the feedback. The terminal may also receive interference information and possible other parameters such as a pilot quality indicator (PQI), an offset factor, and a boost factor from a sector. The terminal may determine transmit power for a second transmission to the sector based on the interference information, the reference power level, and/or the other parameters. The terminal may receive the feedback from one sector and may send the second transmission with CDMA or OFDMA to the same sector or a different sector.

Abstract: PROBLEM TO BE SOLVED: To provide a technique to support simultaneous transmission for more terminals in a multiple access system. SOLUTION: In a single-carrier frequency division multiple access (SC-FDMA) system that utilizes interleaved FDMA (IFDMA) or localized FDMA, a multitude of transmitters transmit their pilots which are orthogonal to one another using time division multiplexing (TDM), code division multiplexing (CDM), interleaved frequency division multiplexing (IFDM), or localized frequency division multiplexing (LFDMA). A receiver performs complementary demultiplexing (non-multiplexing) on the pilots and derives a channel estimate associated with each transmitter using an MMSE technique or a least-squares technique. The receiver separates data transmissions sent on the same time-frequency block through the use of spatial filter matrices. The receiver derives the spatial filter matrices based on the channel estimates and using also a zero-forcing, MMSE, or maximal ratio combining technique. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a method of providing gap indication during sticky assignment. SOLUTION: A method and apparatus are provided to manage the assignment transmission resource of forward and backward links that is assigned to transmitting entity for a certain period of time. When the transmitting entity transmits an actual data packet (e.g. whole or part of intended data or content), assignment of a resource is maintained, and indication is provided, and an erasure signature packet having a first data pattern is transmitted by using the assigned resource when there is no actual data to transmit by using the assigned resource. The data packet and the erasure signature packet are not transmitted, and thereby the assignment of the resource is canceled. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for using different modulation schemes for retransmission of a packet. SOLUTION: A plurality of modulation schemes are used for a single packet, so that each data packet is processed and transmitted in up to T(T>1) blocks. The plurality of modulation schemes are used for the T blocks. A transmitter encodes a data packet to generate code bits. The transmitter then forms a block of code bits using the code bits generated for the packet, determines the modulation scheme to use for the block (e.g., based on a mode/rate), maps the code bits for the block based on the modulation scheme to obtain data symbols, and processes the block of data symbols and transmits the block to a receiver. The transmitter generates and transmits another block in similar manner until the data packet is decoded correctly or all T blocks have been transmitted. The receiver performs complementary processing to receive and decode the packet. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide techniques of efficiently performing signal acquisition in a wireless communication system.SOLUTION: Each base station transmits a TDM pilot 1 generated with a PN1 sequence and a TDM pilot 2 generated with a PN2 sequence. Each base station is assigned a specific PN2 sequence that uniquely identifies that base station. A terminal uses the TDM pilot 1 to detect the presence of a signal and uses the TDM pilot 2 to identify base stations and obtain accurate timing. For signal detection, the terminal performs delayed correlation on received samples and determines whether a signal is present. If a signal is detected, the terminal performs direct correlation on the received samples with the PN1 sequences for K1 different time offsets and identifies K2 strongest TDM pilot 1 instances. For time synchronization, the terminal performs direct correlation on the received samples with the PN2 sequences to detect the TDM pilot 2.
