| 20100246696 | PILOT METHOD FOR 802.16M - A novel pilot method employs a cluster having a particular arrangement of pilot sub-carriers to optimize transmissions under 802.16m, or WiMAX-II. The optimally configured cluster features equal pilot density per OFDM symbol, two or more pilot sub-carriers per cluster, and interlaced pilot sub-carriers, which enables the base stations to successfully boost the pilot sub-carriers, for optimum performance. | 09-30-2010 |
| 20100272033 | HARQ BUFFER MANAGEMENT AND FEEDBACK DESIGN FOR A WIRELESS SYSTEM - A method is disclosed for performing HARQ buffer management. The HARQ buffer management method is a new approach to buffer overflow management that allows the mobile station, rather than the base station, to control the size of its buffer. The HARQ buffer management reports buffer size, buffer occupancy status, and buffer overflow to the base station, to facilitate efficient communication between the base station and the mobile station. | 10-28-2010 |
| 20100273435 | UPLINK FEEDBACK CHANNEL REPORTING MECHANISM IN WIRELESS SYSTEMS - An uplink feedback channel reporting method is disclosed for using the primary and secondary fast feedback channels to efficiently report the channel quality, MIMO feedback, and CQI types of data from a mobile station to a base station. The reporting method reports regular information periodically and non-regular information on demand. | 10-28-2010 |
| 20100287452 | Tail-biting convolutional codes for uplink fast feedback control channel - An apparatus and method for processing fast feedback payload data to generate symbols for transmission through a fast feedback channel in a wireless network are presented. The technique first encodes payload data using a tail biting convolutional code. The encoded bits are then de-multiplexed to five different data subblocks in a sequential fashion. Subblock interleaving is then used to interleave the data of the subblocks according to a predetermine scheme. A bit selector then selects interleaved subblock bit for output. The selected bits may then be modulated by a modulator using quadrature phase shift keying (QPSK). The resulting symbols may then be mapped to a predetermined fast feedback subcarriers within a feedback channel. | 11-11-2010 |
| 20110004804 | Systems and methods for channel coding of wireless communication - Embodiments of an apparatus and method for coding of wireless transmissions channel are generally described herein. Other embodiments may be described and claimed. | 01-06-2011 |
| 20110058522 | METHOD AND APPARATUS FOR TRANSMITTING AN ACK/NACK SIGNAL IN A WIRELESS COMMUNICATION SYSTEM - Machine-readable media, methods, apparatus and system for transmitting ACK/NACK signal in a wireless communication system are described. In some embodiments, a sequence corresponding to one of acknowledge (ACK) information and non-acknowledge (NACK) information may be determined. Then, the sequence may be mapped onto a transmission channel for later transmission from the mobile station to a base station. In some embodiments, the transmission channel may be allocated with at least a part of three feedback mini-tiles (FMTs), wherein each of the FMTs comprises two subcarriers contiguous in frequency domain by six orthogonal frequency division multiplexing (OFDM) symbols contiguous in time domain and the three FMTs being discontinuous in frequency domain. | 03-10-2011 |
| 20110075619 | Apparatus and method for transmitting fast feedback data in wireless systems - Embodiments of the present invention may help facilitate improved performance for high throughput, mobile wireless networks, e.g., IEEE 802.16m, mobile implementations for 3GPP Long Term Evolution (LTE) including LTE advanced mobile phone networks, and other types of high bandwidth networks. In some embodiments, provided are orthogonal sequences with desirable correlation properties for, e.g., 4-6 bits of information, among other things, typically achieving improved performance at varied vehicle speeds. In some embodiments, correlation distances for 6 bits may be less than 3.86, for 5 bits may be less than 3.12, and for 4 bits may be less than 1.95. Additionally, in some embodiments, dedicated coding for PFBCH information may be provided to achieve improved performance for most (if not all) information bits at a relatively wide range of vehicle speeds. Different code sequences for different tiles in one PFBCH channel may be applied for same messages to overcome error floors in high speed scenarios. | 03-31-2011 |
