Abstract:
A base station determines a first set of PUCCH resources to use for a first set of UEs to send acknowledgment information to the base station for a first group of DL subframes. The first set of PUCCH resources starts at a first index. The base station determines a second set of PUCCH resources to use for a second set of UEs to send acknowledgment information to the base station for a second group of DL subframes. The second set of PUCCH resources starts at a second index. The UEs in the first set only use the first set of PUCCH resources. The UEs in the second set use the first and second sets of PUCCH resources. For an UL reception, acknowledgement information is received from the first UEs using the first set of PUCCH resources and from the second UEs using the first and second sets of PUCCH resources.
