Abstract
Method and Apparatus for scheduling transmissions of a plurality of user equipments in a radio communications system including the steps of: transmitting by at least two user equipments of said plurality, of channel information to an access node, said access node serving said at least two user equipments, wherein said channel information includes of a channel matrix; said access node upon reception of said channel information, determining a correlation between said at least two user equipments; said access node comparing said determined correlation to a threshold, and said access node scheduling radio resources for said at least two user equipments based on said comparison.
Claims20
A method, comprising:
- receiving at an access node channel information transmitted by at least two user equipments of a plurality of user equipments in a radio communications system, said access node serving said at least two user equipments, wherein said channel information comprises of a channel matrix;
- determining, by said access node upon reception of said channel information, a correlation between said at least two user equipments, wherein said correlation is determined using subspace analysis spanning the channel matrices of the at least two user equipments, and the subspace analysis is applied to rows and to columns of the channel matrices;
- comparing, by said access node, said determined correlation to a threshold;
- and
- scheduling, by said access node, radio resources for said at least two user equipments based on said comparison.
An apparatus, comprising:
- one or more processors;
- and
- one or more memories including computer program code,
- the one or more memories and the computer program code configured to, with the one or more processors, cause the apparatus to perform at least the following:
- receive channel information transmitted by at least two user equipments of a plurality of user equipments in a radio communications system, said at least two user equipments being served by said apparatus, wherein said channel information comprises a channel matrix;
- determine a correlation between said at least two user equipments, wherein said correlation is determined using subspace analysis spanning the channel matrices of the at least two user equipments, and the subspace analysis is applied to rows and to columns of the channel matrices;
- compare said determined correlation to a threshold;
- and
- schedule radio resources for said at least two user equipments based on said comparison.
A computer program product comprising a non-transitory computer-readable storage medium bearing computer program code embodied therein for use with a computer, the computer program code comprising:
- code for receiving channel information transmitted by at least two user equipments of a plurality of user equipments in a radio communications system, said at least two user equipments being served by an access node, wherein said channel information comprises a channel matrix;
- code for determining a correlation between said at least two user equipments, wherein said correlation is determined using subspace analysis spanning the channel matrices of the at least two user equipments, and the subspace analysis is applied to rows and to columns of the channel matrices;
- code for comparing said determined correlation to a threshold;
- and
- code for scheduling radio resources for said at least two user equipments based on said comparison.
