Abstract
A method includes communicating with a first cell using a first uplink and downlink configuration and a second cell using a second uplink and downlink configuration, said first cell having predetermined configuration; providing communication feedback for said first cell and the second cell on said second cell using a physical uplink shared channel; and determining a codebook size for said feedback in dependence on downlink assignment indicator information received in an uplink grant.
Claims23
A method comprising:
- communicating with a serving cell using a first uplink and downlink configuration and a second secondary cell using a second uplink and downlink configuration, said serving cell having predetermined configuration;
- providing communication feedback for said serving cell and the second cell on said second cell using a physical uplink shared channel, wherein said physical uplink shared channel is scheduled by an uplink grant, wherein a downlink assignment indicator received in an uplink grant is used for the communication feedback, and wherein said serving cell comprises a primary cell that has an uplink system information block set to a configuration 0;
- and
- determining a codebook size for said feedback based on the downlink assignment indicator information received in the uplink grant, wherein the codebook size is determined in dependence on a timing reference uplink or a downlink configuration indicating that the uplink system information block of the primary cell is set to a configuration 0, and wherein the codebook size is determined as if the physical uplink shared channel is not being adjusted by the uplink grant.
