Abstract

Disclosed is multiplexing transmissions of Uplink Control Information (UCI) signals having variable payloads from User Equipments (UEs). The UCI transmission uses a first format type if its size is less than or equal to a predetermined values and it uses a second format type if its size is greater than a predetermined value. When the first format type is used the UE multiplexing is through a first method while when the second format type is used the UE multiplexing is through a second method which is different than the first method. The structure of the second format type is the same as the structure used for the transmission of data information by UEs. The UEs can also be grouped and UCI transmission can be triggered through the reception of control signaling addressing a group of UEs and indicating UCI transmission by a sub-group of UEs in the group of UEs.

Claims

1. A method for transmitting a type of Uplink Control Information (UCI) from a User Equipment (UE) to a Node B over a Physical Uplink Control CHannel (PUCCH), in a communication system, the method comprising the steps of:

transmitting the UCI type using a first PUCCH format if the number of UCI bits is less than or equal to a predetermined value; and

transmitting the UCI type using a second PUCCH format if the number of UCI bits is greater than the predetermined value.
