Abstract
A first amount of bandwidth is allocated to a first wireless device to send signal quality information to a base station. Based on a first indicator of wireless link conditions associated with the first wireless device, and a second indicator of wireless link conditions associated with a second wireless device, a second amount of bandwidth is allocated to the first wireless device to send signal quality information to the base station.
Claims20
A method of allocating signal quality feedback bandwidth, comprising:
- allocating a first amount of bandwidth for a first wireless device to send signal quality information to a base station;
- and,
- based on a first indicator of wireless link conditions associated with the first wireless device, and a second indicator of wireless link conditions associated with a second wireless device, allocating a second amount of bandwidth for the first wireless device to send signal quality information to the base station.
A method of allocating signal quality feedback bandwidth to a plurality of wireless devices, comprising:
- grouping, into at least a first group and a second group, the plurality of wireless devices into a plurality of signal quality feedback bandwidth groups based on an indicator of signal quality feedback bandwidth associated with each of the plurality of signal quality feedback bandwidth groups;
- determining to allocate a first wireless device signal quality feedback bandwidth, the first wireless device not being a member of the plurality of wireless devices;
- selecting the first group from the plurality of signal quality feedback bandwidth groups, the first group being associated with a maximum indicator of signal quality feedback bandwidth of each of the plurality of signal quality feedback bandwidth groups;
- moving a second wireless device from the first group to the second group based on an indicator of channel stability associated with the second wireless device;
- adding the first wireless device to the first group;
- and,
- allocating signal quality feedback bandwidth based on the second group and the first group.
A method of allocating signal quality feedback bandwidth to a plurality of wireless devices, comprising:
- receiving a grouping of the plurality of wireless devices into a plurality of signal quality feedback bandwidth groups based on an indicator of signal quality feedback bandwidth associated with each of the plurality of wireless devices, the plurality of signal quality feedback bandwidth groups comprising a first group and a second group;
- selecting the first group, the first group being associated with a minimum indicator of signal quality feedback bandwidth of each of the plurality of signal quality feedback bandwidth groups;
- moving a first wireless device from the first group to the second group based on an indicator of channel stability associated with the first wireless device;
- and,
- allocating signal quality feedback bandwidth based on the first group and the second group.
