Abstract
A method including: using first information and second information to determine a code book size, said first information including information for at least one first subframe of at least one cell for which feedback information is to be provided, said at least one first subframe is prior to subframe n and second information for at least one second subframe of at least one cell for which feedback information is to be provided, said at least one second subframe being after said subframe n; and using said code book size for providing feedback information.
Claims27
A method comprising:
- using, by a user equipment, first information and second information to determine a code book size for an ACK/NACK codebook, the first information comprising information about at least one first subframe of at least one cell for which feedback information is to be transmitted, the at least one first subframe being no later than subframe n and the second information comprising information about at least one second subframe of at least one cell for which feedback information is to be transmitted, the at least one second subframe being after the subframe n;
- wherein the first information and the second information together comprise information about a plurality of different cells, and wherein the plurality of different cells use different uplink downlink time division duplex configurations;
- and
- causing, by the user equipment, the feedback information, based on the code book size, to be transmitted;
- wherein the ACK/NACK codebook is generated according to a maximum number of actually scheduled type 1 downlink subframes plus a maximum number of type 2 downlink subframes, and wherein the type 1 downlink subframes comprise downlink subframes no later than the subframe n and a corresponding positive or negative acknowledgement transmitted on a physical uplink shared channel scheduled in the subframe n, and wherein the type 2 downlink subframes comprise downlink subframes later than the subframe n and the corresponding positive or negative acknowledgement transmitted on the physical uplink shared channel scheduled in the subframe n.
