摘要： Aspects of the present application provide methods and device for use in User Equipment (UE) cooperation. UE cooperation may include the cooperating UEs (CUEs) forwarding traffic to or from one or more target UEs (TUEs) with redundant signal transmissions or receptions. Methods involve a base station transmitting configuration information to at least one cooperative user equipment (CUE) and to a target user equipment (TUE). The configuration information includes an indication of resources for a sidelink (SL) transmission and a redundancy parameter for the SL transmission. The SL transmission is a transmission for the at least one CUE to forward a packet intended for the TUE. The base station also transmits the packet intended for the TUE, to a plurality of UEs comprising the at least one CUE and the TUE.

摘要： The present disclosure relates to uplink cooperative multi-User Equipment (UE) cooperative transmission such as Multiple-Input Multiple-Output (MIMO) transmission. Source data of a source UE that is to be transmitted via uplink cooperative transmission by multiple UEs, is transmitted to at least one cooperative UE over an SL. The source data is associated with an identifier for identifying the UE to the network equipment as a source of the source data. The multiple UEs transmit the source data and the identifier in an uplink direction to the network equipment. The network equipment receives the source data from the multiple UEs in a cooperative transmission such as cooperative MIMO transmission, and obtains the identifier for identifying the source UE as the source of the source data.

摘要： Signaling to enable relay-based user equipment (UE) cooperation (UC) by a group of UEs, and a configuration including an adaptation protocol for processing of UC bearer traffic, are communicated in a wireless communication network. The UC bearer traffic includes a UC bearer and UC bearer attributes, and the UC bearer includes either a split bearer or a duplicated bearer indicated in the UC bearer attributes. In some embodiments, wireless network connectivity that is available for a relay link is determined, and the adaptation protocol is determined based on the determined connectivity. Signaling to enable configuration of the relay link in accordance with the connectivity and the adaptation protocol is communicated. A UE may receive signaling to configure the UE for such a relay link, and communicates traffic between a remote UE and the wireless communication network over the relay link.

摘要： One embodiment of coordinated multiple relay link wireless communication with User Equipment (UE) cooperation involves coordinating, with a primary relay link between a UE and a wireless communication network, configuration of a secondary relay link between the UE and the wireless communication network; and communicating signaling to enable configuration of the secondary relay link in accordance with the coordinating. After the primary relay link and the secondary relay link have been configured, communications with the UE are coordinated over the primary relay link and the secondary relay link. Other embodiments may involve first and second relay links for a UE, and such relay links for a UE may be between the UE and a wireless communication network, or between the UE and another UE in the case of UE-to-UE relay links.

摘要： Aspects of the present application provide methods and devices for use in User Equipment (UE) cooperation. A packet transmitted between a base station and a UE or between UEs includes a packet destination identifier that identifies a destination of the packet. A receiving the packet from a base station or another UE can determine whether the UE is the destination of the packet. When the UE is the destination of the packet, the UE decodes the packet. When the UE is not the destination of the packet, the UE forwards the packet to another UE. The packet may include a packet source identifier that can be used by the destination to determine where the packet originated. In some instances, the cooperative UEs do not need to decode the entire packet to be able to determine the destination of the packet and therefore can forward the packet along with less processing.
