US 8,897,317 B2 · Distributed capacity based channel assignment for communcation systems

Abstract

Apparatuses and methods for providing distributed capacity based channel assignment in a radio frequency base station servicing a local area. A method can include determining that an additional channel is needed, receiving reports from user equipment connected to the base station over the air interface indicating the gain in capacity due to the added channel, adding the new channel, receiving loss reports from one or more neighboring base stations indicating the loss in capacity and the interference caused to user equipments serviced by the neighboring base stations due to the use of the new channel. The method can also include comparing the gain in capacity to the loss of capacity by the worst user connected to the neighboring base stations due to the added channel and determining whether to continue to add the channel to increase capacity.

Dependent claims

A method, comprising:

determining in a network device servicing a local area that an additional channel is needed;
receiving a report from a user equipment connected to the network device over an air interface indicating a gain in capacity that would occur due to the additional channel;
adding a new channel;
receiving a loss report from one or more neighboring network devices indicating a loss in capacity of, or interference caused to at least one user equipment serviced by, the one or more neighboring network devices;
comparing the gain in capacity to the loss in capacity of, or interference caused to, the at least one user equipment;
and
determining whether, based on the comparison, to continue to add the new channel to increase capacity,
wherein the receiving the loss report comprises receiving a loss report indicating the loss in capacity of, or interference caused to the at least one user equipment serviced by the one or more neighboring network devices due to the use of the new channel.

5 more elements

An apparatus, comprising:

at least one processor;
and
at least one memory including computer program code,
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to
determine in a network device servicing a local area that an additional channel is needed,
process a report received from a user equipment connected to the network device over an air interface indicating a gain in capacity that would occur due to the additional channel,
add a new channel,
process a loss report received from one or more neighboring network devices indicating a loss in capacity of, or interference caused to at least one user equipment serviced by, the one or more neighboring network devices,
compare the gain in capacity to the loss in capacity of, or interference caused to, the at least one user equipment, and
determine whether, based on the comparison, to continue to add the new channel to increase capacity,
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to process the loss reports by processing loss reports indicating the loss in capacity of, or interference caused to the at least one user equipment serviced by, the one or more neighboring network devices due to the use of the new channel.
