    摘要: Briefly, in accordance with one or more embodiments, data transmitted from a transmitter is received in a downlink channel, and channel quality data is fed back to the transmitter in a first uplink channel or in a second uplink channel. Channel quality data is feedback at a lower rate on the first uplink channel and channel quality data is feedback at a higher rate on the second uplink channel in the event there is a higher amount of data to be fed back. Link adaptation may be utilized to select a transmission rate on the second uplink channel, wherein the transmission rate is selected based at least in part on a channel condition or a user location.

    摘要: 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.

    摘要: 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.

    摘要: 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.
