Method for realizing eca supporting up to 32 ccs and enhancing dynamic pucch resource allocation for associated use

A control signaling method for use in an advanced wireless communication system, the wireless communication system including:

• an Evolved NodeB (eNB);
• and
• at least one advanced user equipment (UE),
• wherein the wireless communication system is capable of carrier aggregation (CA) with up to 32 downlink (DL) component carriers (CCs or cells) but only a single uplink (UL) CC, and control signaling between the eNB and a UE is operable in the following CA modes:
• a self-scheduling mode wherein the control signaling method comprises performing control signaling between the eNB and the UE such that all CCs are configured as self-scheduling CCs;
• a cross-carrier scheduling mode wherein the control signaling method comprises performing control signaling between the eNB and the UE such that one or more DL CC(s) is/are configured as scheduling CC(s) which provide scheduling information for DL data reception at the UE on the remaining CCs as scheduled CCs;
• and
• a hybrid CA mode wherein the control signaling method comprises performing control signaling between the eNB and the UE such that the UE is configured to operate in the cross-carrier scheduling mode on a group or groups of DL CCs and in the self-scheduling mode on the remaining DL CCs.
