Title: PUCCH RESOURCE ALLOCATION
Abstract:
In a first subframe (210-2-210-5), data is sent by a network node in a DL shared channel (240) and a timing indicator (570) is sent in a PDCCH (220) to UE, the timing indicator (570) indicating an offset relative to the first subframe (210-2-210-5) the UE should use in order to determine a second subframe (210-7) to use to send, in a PUCCH (230), acknowledgement information for the data received in the DL shared channel (240) of the first subframe (210-2-210-5). The acknowledgement information is received by the network node from the UE in the PUCCH (230) of the second subframe (210-7). The UE receives the data and timing indicator (570) and determines the second subframe (210-7) using at least the timing indicator (570). The UE transmits the acknowledgement information in the PUCCH (230) of the second subframe (210-7). Apparatus, computer programs and products, and methods are disclosed.
