1. A method, comprising:
- in a receiver, receiving from a transmitter a request to provide channel feedback relating to a communication channel between the transmitter and the receiver;
assessing a maximum latency after which the channel feedback is expected by the transmitter;
selecting, based on the assessed maximum latency, a spectral resolution with which to calculate the channel feedback; and
calculating the channel feedback with the selected spectral resolution, and sending the calculated channel feedback to the transmitter within the maximum latency.

Abstract
A method in a receiver includes receiving from a transmitter a request to provide channel feedback relating to a communication channel between the transmitter and the receiver. A maximum latency after which the channel feedback is expected by the transmitter is assessed. A spectral resolution with which to calculate the channel feedback is selected based on the assessed maximum latency. The channel feedback is calculated with the selected spectral resolution, and the calculated channel feedback is sent to the transmitter within the maximum latency.

7. A method, comprising:
-
in a transmitter that transmits to multiple receivers, assessing respective spectral resolutions with which the receivers are capable of providing channel feedback to the transmitter; based on the assessed spectral resolutions, forming a group that comprises two or more of the receivers; and transmitting from the transmitter jointly to the receivers in the group. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method, comprising:
-
in a transmitter that transmits to multiple receivers, defining a full set of spectral resolutions with which the receivers are permitted to provide channel feedback to the transmitter, and a partial subset of the full set; evaluating a criterion relating to a given receiver; and based on the evaluated criterion, instructing the given receiver whether to select the spectral resolution from the full set or from the partial subset. - View Dependent Claims (19, 20, 21, 22, 23, 24)
