Claim:
1. A system, comprising: user interfaces that include a display, a speaker, and a microphone; and a communication device coupled with the user interfaces to transmit and receive data over a wireless network, the communication device including: a hybrid automatic repeat request-acknowledgement (HARQ-ACK) module to generate a HARQ-ACK bit stream to indicate whether downlink data was successfully received on a physical downlink shared channel (PDSCH); a transmit module coupled with the HARQ-ACK module to receive the HARQ-ACK bit stream and further coupled with the channel state indicator module to receive the CSI bit stream, the transmit module to: recognize a potential collision between transmission of periodic CSI and transmission of hybrid automatic repeat request-acknowledgement (HARQ-ACK) in a subframe; determine a number of uplink control information (UCI) bits, which includes CSI bits of the CSI bit stream and acknowledgement/negative acknowledgement (ACK/NACK) bits of the HARQ-ACK bit stream, to be transmitted in the subframe with utilization of a physical uplink control channel (PUCCH); if the number is not greater than a threshold, spatially bundle the ACK/NACK bits by having a most significant bit represent spatially-bundled HARQ-ACK for a primary cell and a least significant bit represent spatially-bundled HARQ-ACK for a secondary cell, and modulate the spatially-bundled ACK/NACK bits on a second reference signal (RS) symbol of the subframe and modulate encoded CSI bits on non-RS symbols; and if the number is greater than the threshold, jointly code the CSI bits and the ACK/NACK bits and modulate the jointly encoded CSI bits and ACK/NACK bits on non-RS symbols of the subframe.
