FIELD: radio engineering, communication.
SUBSTANCE: base station determines the first set of PUCCH channel resources for use by the first set of UEs to send the acknowledgment information to the base station for the first group of DL subframes. The first set of resources of the PUCCH begins with the first index. The base station determines a second set of PUCCH channel resources for use by the second set of UEs for transmitting to the base station the acknowledgment information for the second group of DL subframes. The second set of resources of the PUCCH begins with the second index. The UEs in the first set only use the first set of PUCCH channel resources. The UEs in the second set usage of the first and second sets of resources of the PUCCH. For uplink reception, the acknowledgment information is received from the first UE devices using the first set of PUCCH channel resources and from the second UE devices using the first and second PUCCH channel resource sets.
EFFECT: increase of the bandwidth transmission.
