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 facilitate transmitting control data over one or more scrambled logical channels.SOLUTION: Control data values are easily multiplexed over a single physical control channel at least in part by dividing the control channel into one or more logical channels. The physical control channel can have a corresponding Walsh space for transmitting a number of bits, or representation thereof, and the Walsh space can be divided among the logical control channels. Additionally, the logical control channels and/or physical channel are scrambled according to an identifier of a mobile device (such as a MAC ID) to differentiate the data on the channel. Furthermore, a sector identifier is used to scramble the data where the sector is ascertainable.

Abstract: PROBLEM TO BE SOLVED: To provide techniques to flexibly support different bandwidths in a wireless communication system.SOLUTION: The system supports a configurable operating bandwidth using a fixed design bandwidth and variable guard bands. Values for various parameters such as fast Fourier transform (FFT) size, cyclic prefix length, and sample rate may be selected based on the design bandwidth. The design bandwidth may be associated with K total subcarriers. Different operating bandwidths may be supported by selecting different numbers of usable subcarriers. A transmitter and a receiver may perform processing for a transmission using the same FFT size, cyclic prefix length, and sample rate regardless of the selected operating bandwidth. The system may use different operating bandwidths and/or different parameter values for different portions of a transmission.

Abstract: PROBLEM TO BE SOLVED: To provide a system and method of providing an indication of a gap in transmission, so that the access point and access terminal do not interpret the gap in the transmission as indication of not requiring the assigned resources or as an indication that the assigned resources were no longer available.SOLUTION: A method and apparatus are provided to manage the assignment transmission resource of forward and reserve link that is assigned to transmitting entity for a period of time. An indication of a gap is provided whenever the transmitting entity is not transmitting actual data packets (e.g. whole or part of intended data or content), yet the transmitting entity is to maintain the assignment of the allocated resource. For example, an erasure signature packet comprising a first data pattern is transmitted on the assigned resource when there is no actual data to transmit on the assigned resource.

Abstract: PROBLEM TO BE SOLVED: To provide a method of performing rank step-down for MIMO SCW (single code word) design employing HARQ.SOLUTION: Systems and methods are described that facilitate reducing rank (e.g., of a user device) as a number of transmissions from the user increases. Such rank step-down can improve interference resistance and facilitate maintaining code rate despite transmission propagation. Rank step-down information is encoded along with CQI information to generate a 5-bit CQI signal that can facilitate updating a user's rank upon each CQI transmission (approximately every 5 msec). The described systems and/or methods can be employed in a single code word (SCW) wireless communication environment with a hybrid automatic request (HARQ) protocol.
