System and method for combined MAC level message with CQI channel control message for channel feedback report

摘要

In one or more embodiments, a system and method of managing network channel quality in a wireless communications network includes reporting a channel quality measurement from the particular user to a base station (BS) over an available CQICH, and determining a MCS based, at least in part, upon the channel quality measurement. If a threshold network CQICH capacity is reached during a subsequent data frame such that a CQICH is no longer available, MAC level messages are generated between the BS and the particular user to trigger reporting of signal quality information to the BS by the particular user. After the next CQICH cycle commences and if a CQICH is still unavailable, the signal quality information is continued to be provided via MAC level messages. Otherwise, a CQICH is reallocated for a particular user and channel quality measurement reporting is transitioned back to the CQICH.

主权项

1. A network node in a wireless packet-based communications system, the network node comprising:
a processor and memory operatively coupled to each other and to a network connection, wherein the processor is configured to: selectively transition between an available channel quality information channel (CQICH) and a Medium Access Control (MAC) level message to communicate channel signal quality reporting information related to a particular user over the network connection either using the available CQICH or using the MAC level message, but not both, wherein the selective transition is done in response to whether a CQICH is available during one or more data frames; either process the channel signal quality reporting information received via the MAC level message if a CQICH is unavailable, or process the channel signal quality reporting information received over the available CQICH; implement a certain modulation coding scheme (MCS) for the particular user based, at least in part, upon the channel signal quality reporting information; and after processing the channel signal quality reporting information received via the MAC level message responsive to a CQICH not being available during a preceding CQICH cycle, process the channel signal quality reporting information for the particular user using a different CQICH during a subsequent CQICH cycle.
