Abstract: Resource blocks in a Long Term Evolution (LTE) network may be allocated by determining a maximum number of user equipments (UEs) in the LTE network that are permitted to transmit in a time period using a given resource block. This maximum number of UEs may be determined according to an upper limit on the overall transmission power in the LTE network for the given resource block. The given resource block may be allocated in the time period to up to the maximum number of UEs based on each UE's geographic location within the network. Related systems, methods, and devices are disclosed.

Abstract: 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.
