Abstract: PROBLEM TO BE SOLVED: To increase system capacity in a code-limited WCDMA(R) (e.g., TDD, FDD, ...) wireless communication environment.SOLUTION: A larger code space can be defined by introducing multiple code clusters within a sector, where each cluster has a unique scrambling code. Codes within a cluster have orthogonal Walsh sequences that can be assigned to user devices to facilitate communicating over a wireless network and can overlap with codes in another cluster. The unique scrambling code assigned to each cluster can ensure that duplicate Walsh sequences in another cluster in the same sector appear as pseudo-noise codes.

Abstract: PROBLEM TO BE SOLVED: To provide a frame structure and a transmission technique for a wireless communication system. SOLUTION: In a single frame structure 200, a superframe includes a plurality of outer frames, each of the outer frames includes a plurality of frames, and each of the frames includes a plurality of time slots. The time slots in each superframe are allocated to downlink and uplink and to different wireless techniques (for example, W-CDMA and OFDM) based on loading. Each physical channel is allocated to time slots in the frames of each outer frame in the superframe. An OFDM waveform is generated for an OFDM slot of each downlink, a W-CDMA waveform is generated for a W-CDMA slot of each downlink, and the waveforms are multiplexed on each slot. A modulation signal is generated for the multiplexed W-CDMA and OFDM waveform and transmitted on the downlink. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a wireless communication system with a configurable cyclic prefix length.
SOLUTION: To transmit data in a manner to mitigate the deleterious effects of delay spread, the expected coverage areas for multiple transmissions to be sent in multiple time slots are initially determined. Cyclic prefix lengths for these transmissions are selected based on the expected coverage areas. The cyclic prefix length for each transmission may be selected from among a set of allowed cyclic prefix lengths on the basis of the expected coverage area for that transmission, the pilot staggering used for the transmission, and so on. For example, a shorter cyclic prefix length may be selected for each local transmission, and a longer cyclic prefix length may be selected for each wide-area transmission. The selected cyclic prefix lengths may be signaled to the terminals.

Abstract: PROBLEM TO BE SOLVED: To provide a technique for using a plurality of modulation methods for retransmission of augmentative redundancy, etc. of a single packet. SOLUTION: Each data packet is processed and is transmitted with a block of T at the maximum, where T>1. In order to achieve proper performance, a plurality of modulation methods are used for the block of T. A transmitter encodes the data packet to generate a code bit. Next, the transmitter generate a code bit block using the code bit generated for the packet, and determines a modulation method to be used for the block (based on a selected mode/rate). Then, the transmitter maps the code bit for the block based on the modulation method to obtain a data symbol, and processes and transmits a data symbol block to a receiver. The transmitter generates and transmits other blocks by the same method until a data packet is decoded correctly or all T blocks are transmitted. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To estimate reverse link loading in a wireless communication system.SOLUTION: The reverse link interference is measured and reverse link receiver noise is measured. The reverse link interference is compared to the reverse link receiver noise by dividing the interference power by the receiver noise power. The reverse link receiver noise is measured in an OFDMA system by nulling transmission from access terminals within a cell and nearby during a null time and frequency interval. To measure the reverse link interference, local null time and frequency intervals are designated, the access terminals within the cell null their transmissions during the designated local null time and frequency intervals, and interference power is measured in the local null time and frequency intervals. Alternatively, the interference power is measured by subtracting pairs of pilot symbols that are contiguous to each other in time or frequency.

Abstract: PROBLEM TO BE SOLVED: To provide methods and apparatuses that apply a time-varying delay to symbols to be transmitted from one or more antennas.SOLUTION: A transmit data processor 202 demultiplexes transmit data into Nnumber of data streams, and encodes and interleaves the data streams. A MIMO processor 204 causes the Nnumber of data streams to undergo symbol mapping and modulation to generate modulation symbols, which are then converted into their time-domain representations in IFFT blocks, provided with a cyclic prefix, and each provided with a time-varying delay. In one embodiment, the delay varies among a plurality of symbols to be consecutively transmitted. In another embodiment, all of the symbols in a frame or burst period have the same delay with each frame or burst period having a different delay for each symbol than a preceding or following frame or burst period.

Abstract: PROBLEM TO BE SOLVED: To improve network interference management for wireless networks.SOLUTION: Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.
