Abstract: 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.

Abstract: 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.

Abstract: 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.

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.
