The first PDCCH indicates a resource allocation of a first PDSCH transmitted on a first time-frequency resource. The wireless device decodes data carried in the first PDSCH according to the first PDCCH. The wireless device obtains a resource allocation of a second PDSCH based on a mapping rule. The mapping rule maps resources of the first PDSCH to resources of the second PDSCH. The wireless device generates encoded bits for the second PDSCH. The encoded bits are based on the decoded data carried in the first PDSCH and the resource allocation of the second PDSCH. The wireless device generates reference signals associated with the second PDSCH. The wireless device transmits the encoded bits to a user equipment (UE). The encoded bits are transmitted on the resources of the second PDSCH on the second time-frequency resource. ## Claims ### Claim 1 A method of wireless communication of a wireless device, comprising: receiving, from a base station, a first physical downlink control channel (PDCCH) that indicates a resource allocation of a first physical downlink shared channel (PDSCH) transmitted on a first time-frequency resource;
