In one exemplary embodiment a network node (such as a base station BS) determines that a plurality of user equipments UEs are available for use as mobile relays MRs, and selects a subset of the plurality of UEs and configures the subset of the plurality of UEs as MRs. In another exemplary embodiment, an indication is sent (for example from a UE) that a UE is willing to operate as a MR, a response is received that the UE is selected to be a MR1 and then periodically there is sent a beacon advertising that the UE is a MR. In this manner UEs are pre-configured in a cell as MRs, regardless of any specific UE need for relay services. Any UE later needing relay service listens for the beacon. The BS can limit which UEs it pre-configures as MRs to avoid closely spaced UEs being both active MRs. Locations need not be signaled. |
