Abstract
Methods and apparatus are provided for a base station to enable a user equipment (UE) configured for operation with carrier aggregation over a number of cells to determine cells and transmission time intervals (TTIs) where the base station transmits data information to the UE and for the UE to determine and arrange corresponding acknowledgement information in a codeword.
Claims11
A method, comprising:
- receiving a configuration for first resources for transmission of a physical uplink control channel (PUCCH) and for second resources for transmission of the PUCCH, wherein the first resources differ from the second resources;
- receiving a configuration for a threshold for a number of control information bits to be transmitted in the PUCCH, the configuration indicating one value of a plurality of values for the threshold, wherein the value is larger than 2;
- receiving a downlink control information (DCI) format indicating a resource from at least one of the first resources or the second resources for transmission of the PUCCH;
- transmitting control information in the PUCCH in the resource from the first resources when the number of the control information bits is smaller than or equal to the threshold;
- and
- transmitting the control information in the PUCCH in the resource from the second resources when the number of the control information bits is larger than the threshold,
- wherein:
- the resource from the first resources includes a first number of resource blocks (RBs) in a frequency domain and the resource from the second resources includes a second number of RBs in the frequency domain,
- the first number of RBs is smaller than the second number of RBs, and
- a same PUCCH format is used when the PUCCH transmission is in a resource from the first resources and when the PUCCH transmission is in a resource from the second resources.
