Claims20
A resource allocation method for reducing an uplink feedback overhead in a wireless communication system, the method comprising:
- scheduling downlink traffic and determining a transmission period;
- and
- allocating uplink feedback resources considering the downlink traffic transmission period.
A base station operation method for uplink feedback allocation in a wireless communication system, the method comprising:
- scheduling downlink traffic for a plurality of mobile stations;
- grouping mobile stations having the same downlink traffic transmission period;
- and
- allocating uplink feedback resources considering the downlink traffic transmission period together with the grouping information.
A downlink scheduling method of a base station for uplink feedback allocation in a wireless communication system, the method comprising:
- buffering downlink traffic and delaying resource allocation;
- identifying traffic transmission timing for the buffered downlink traffic;
- and
- requesting for feedback resource allocation at the downlink traffic transmission timing.
A base station comprising:
- a downlink scheduler for scheduling downlink traffic and determining a downlink transmission period;
- and
- an uplink scheduler for allocating uplink feedback resources considering the downlink traffic transmission period.
A base station for uplink feedback allocation in a wireless communication system, the base station comprising:
- a downlink scheduler for scheduling downlink traffic for a plurality of mobile stations and grouping a number of the plurality of mobile stations having the same downlink traffic transmission period;
- and
- a uplink scheduler for allocating uplink feedback resources considering the downlink traffic transmission period together with the grouping information.
A base station for uplink feedback allocation in a wireless communication system, the BS comprising:
- a downlink scheduler for buffering downlink traffic, delaying resource allocation, and identifying traffic transmission timing for the buffered downlink traffic;
- and
- a uplink scheduler for requesting for feedback resource allocation at the downlink traffic transmission timing.
A wireless communications network comprising a plurality of base stations, wherein each of the plurality of base stations comprising:
- a downlink scheduler for scheduling a downlink traffic and determining a downlink transmission period;
- and
- an uplink scheduler for allocating uplink feedback resources considering the downlink traffic transmission period.
