Abstract
A method of wireless communication includes determining a capacity of a control channel based on whether multiplexing of acknowledgement/negative acknowledgement (ACK/NAK) bits for multiple component carriers with periodic channel state information (CSI) is allowed. A threshold for a number of ACK/NAK bits is determined based at least in part on a payload size of the periodic CSI and the determined capacity. The method also includes bundling ACK/NAK bits when a number of the ACK/NAK bits is greater than the determined threshold. The ACK/NAK bits and the periodic CSI are transmitted via the control channel.
Claims25
A method of wireless communication, comprising:
- determining a capacity of a control channel based at least in part on whether multiplexing of acknowledgement/negative acknowledgement (ACK/NAK) bits for a plurality of component carriers with periodic channel state information (CSI) is allowed, in which determining whether multiplexing ACK/NAK bits for the plurality of component carriers with the periodic CSI is allowed is based at least in part on a semi-static configuration;
- determining a threshold for a number of ACK/NAK bits based at least in part on a payload size of the periodic CSI and the determined capacity;
- bundling ACK/NAK bits when the number of ACK/NAK bits is greater than the determined threshold;
- and
- transmitting the ACK/NAK bits and the periodic CSI using the control channel.
