Abstract
In a wireless network comprising a plurality of subscriber stations and a base station capable of providing service to the subscriber stations, a subscriber station is provided that includes a rank selector and a scheduling data reporter. The rank selector is operable to select a rank for the subscriber station. The rank is operable to identify a number of antennas for transmitting data streams from the base station to the subscriber station. The scheduling data reporter is operable to report scheduling data, including the rank, to the base station.
Claims25
In a wireless network comprising a plurality of subscriber stations and a base station capable of providing service to the subscriber stations, a subscriber station comprising:
- a rank selector operable to select a rank for the subscriber station, the rank operable to identify a number of antennas for transmitting data streams from the base station to the subscriber station;
- and
- a scheduling data reporter operable to report scheduling data to the base station, the scheduling data comprising the rank.
A method for scheduling users in a base station based on user-determined ranks in a MIMO system, comprising:
- receiving scheduling data from each of a plurality of users, the scheduling data for each user comprising at least one CQI, a rank and a preferred pre-coding matrix;
- and
- scheduling the users based on the scheduling data.
A method for communicating between a transmitter and a receiver in a MIMO system, comprising:
- receiving a frame from the transmitter at the receiver, the frame comprising a plurality of codewords, each codeword corresponding to a different HARQ channel;
- and
- processing the frame using HARQ messaging.
