摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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
