    摘要： Signaling for allocating communication resources is communicated in a wireless communication network. The signaling is for allocating the communication resources in a first time duration and a second time duration for relaying data, in respective hops of a multi-hop relay between first and second end nodes, by user equipment (UE) including one or more relay UEs at each hop for example. Such relaying of data in the respective hops involves relaying the data in a first hop of the multi-hop relay and in a second hop of the multi-hop relay between the first end node and the second end node. The communication resources in the first time duration are allocated for relaying the data in the first hop of the multi-hop relay and the communication resources in the second time duration are allocated for relaying the data in the second hop of the multi-hop relay.

    摘要： Multiple communication paths are established for communications between a User Equipment (UE) and a wireless communication network, before switching between those paths is initiated. Signaling that includes an explicit indication that the UE is to switch between the multiple communication paths is transmitted to and received by at least the UE for which the multiple communication paths were established. Responsive to the explicit indication, communications are switched between the communication paths. At least one of the communication paths includes a relay path between the UE and the wireless communication network through another UE. Establishment of the multiple paths in advance of the switching may be useful in enabling fast switching with low latency and/or no traffic loss.

    摘要： Methods and apparatuses are described for cooperation of two or more devices to improve the transmissions over a Uu interface. A source receives or transmits an indicator indicating a first mode of two modes of cooperation between the source apparatus and at least a first cooperating device. The two modes of cooperation includes a joint communication mode and a relay mode of cooperation. If the first mode is the joint communication mode, at least a portion of the data, intended for the intended recipient, is transmitted to at least the first cooperating device to be further transmitted by the first cooperating device to the intended recipient. A same or different portion of the data is transmitted to the intended recipient or to a second cooperating device to be further transmitted by the second cooperating device to the intended recipient.
