Abstract:
1. A method of managing network channel quality for a particular user in a wireless communications network, the method comprising: if one of a plurality of channel quality information channels (CQICH) is available during a first data frame, reporting a channel quality measurement from the particular user to a base station (BS) over the available CQICH, and assigning a modulation coding scheme (MCS) based, at least in part, upon the channel quality measurement; if a threshold network CQICH capacity is reached during a subsequent data frame and if one of the plurality of CQICH is not available, generating Medium Access Control (MAC) level messages between the BS and the particular user to trigger reporting of signal quality information to the BS by the particular user; receiving the reported signal quality information at the BS at least until a next CQICH cycle commences and determining whether one of the plurality of CQICH is available during the next CQICH cycle; if a CQICH is not available during the next CQICH cycle, continuing to receive the signal quality information via the MAC level messages or, otherwise, allocating an available CQICH for reporting the channel quality measurement from the particular user to the BS.
